Osteoporosis becomes a serious health threat for older postmenopausal women by predisposing them to an increased risk of fracture.
Osteoporosis and associated fractures are an important cause of morbidity and mortality. Special attention is being paid to
early detection, management, and treatment of postmenopausal osteoporosis in women. Biochemical markers can enable dynamic
and rapid measurement of total body skeletal metabolism and will be clinically useful in the management of postmenopausal
osteoporosis women (PMO) and also for assessing the effects of antiresorptive therapy. With this view, we planned to assess
osteoclastic activity by determining urinary hydroxyproline in osteoporotic women. The aim of this study is to measure urinary
hydroxyproline (expressed as mg of hydroxyproline/g of creatinine) and serum ascorbic acid in postmenopausal women with osteoporosis
and without osteoporosis. These biochemical parameters were determined 3 months post antiresorptive therapy (alendronate + calcium + vitamin
D) in postmenopausal osteoporosis patients. 60 postmenopausal women with osteoporosis in the age group 45–60 years and 60
healthy postmenopausal women (normal bone mineral density) in the same age group were included in the study. Urinary hydroxyproline
levels were significantly increased (P < 0.001) in PMO at baseline level as compared to control group. These levels were decreased significantly (P < 0.001) post therapy in PMO patients. Serum vitamin C levels were significantly decreased (P < 0.001) in PMO patients at baseline level as compared to controls. No significant change occurred of serum vitamin C level
post therapy. Raised excretion of hydroxyproline at the baseline level might be due to increased degradation of collagen type
I from the bone matrix in osteoporosis. Breakdown of collagen seems to be lowered as reflected by lowering of hydroxyproline
excretion post antiresorptive therapy. Alteration in the concentration of this marker can be very well utilized to monitor
the effectiveness of therapy. Thus simple, direct urinary assay to measure bone resorption is very useful in monitoring the
therapy in PMO and may become an integral part of the management of osteoporosis. 相似文献

To evaluate the magnitude of bone loss in postmenopausal women and to study the effect of a selective estrogen Receptor Modulator,
raloxifene, on bone loss by quantitative ultrasound of calcaneus and serum bone specific alkaline phosphatase (BAP). Postmenopausal
women with ostesopenia/osteoporosis were assigned randomly to receive placebo (n=30) or raloxifene (60mg/d, n=30) with calcium
(500mg/day) and vitamin D (250 IU/day). The bone mineral density (BMD) and BAP levels were measured at the beginning of therapy
and six months later. They were subjected to statistical analysis (t test, p value) using SPSS statistical package. 70% of
postmenopausal women suffered from osteopenia/osteoporosis. After raloxifene therapy, there was improvement in the BMD but
this was not statistically significant (p>0.05). There was a fall in the value of serum BAP by 26.6% (p<0.05). Raloxifene
has a favourable effect on bone turnover as evident from changes in BMD and a significant fall in serum BAP. 相似文献

The awareness of osteoporosis has grown world wide in recent years. This silently progressing metabolic bone disease is widely
prevalent in India, and osteoporotic fractures are a common cause of morbidity and mortality in adult Indian men and women.
Rapid bone loss occurs in postmenopausal women due to hormonal factors which lead to increased risk of fractures. Biochemical
markers of bone metabolism are used to assess skeletal turnover. A cross-sectional study of 150 pre- and post menopausal women
was carried out at S.D.M College of Medical Sciences and Hospital, Dharwad, during the period of May 2005 to September 2005.
The study group consisted of 75 Premenopausal women in the age group of 25–45 years and 75 Postmenopausal women in the age
group of 46–65 years. Bone formation markers (Total Calcium, lonised calcium, Phosphorus, Alkaline phosphatase), and bone
resorption markers (Urinary Hydroxyproline) were analysed in pre and post menopausal women. Bone formation markers, Total
and lonised calcium were significantly decreased (p<0.001) and Alkaline phosphatase was significantly increased (p<0.001)
in postmenopausal women compared to premenopausal women. Bone resorption markers, Urinary hydroxyproline excretion was significantly
increased (p<0.001) in postmenopausal women. The results from this study suggest that simple, easy, common biochemical markers
can still be used to assess the bone turnover in postmenopausal women and hence their risk of developing osteoporosis and
fractures. 相似文献

Osteoporosis is a systemic disease with a strong genetic component. Vitamin D receptor (VDR) has been suggested as a candidate gene for osteoporosis. Therefore the present study was aimed to investigate the pattern of allelic variants of VDR gene polymorphism (FokI and BsmI), its influence on vitamin D levels and bone mineral density (BMD) in North Indian postmenopausal women with osteoporosis for possible genetic association. 254 postmenopausal osteoporotic women and 254 postmenopausal non osteoporotic women were included in the study. VDR FokI and BsmI gene polymorphism gene were assessed by the PCR-RFLP method. Serum 25-hydroxyvitamin D was measured by the ELISA. BMD at the L1–L4 lumbar spine, hip, forearm and femoral neck was assessed by dual energy X-ray absorptiometry. The average BMD at spine and hip in postmenopausal women with bb and spine, hip, femoral neck and forearm with ff genotype had significantly low BMD. The frequency of ff genotype and f allele was significantly higher in postmenopausal osteoporotic women when compared with postmenopausal non osteoporotic women. However, no significant association was found between the genotypes and vitamin D levels. Our study reveals that VDR gene FokI and BsmI polymorphism is significantly associated with low bone mineral density. Therefore the ff genotype and f allele of VDR FokI gene may be used as an important risk factor for osteoporosis. 相似文献

The purpose of this study was to find out the effect of lead exposure on systolic and diastolic blood pressure, heme biosynthesis
related and hematological parameters of automobile workers. For this study 30 automobile workers were selected and compared
with 30 age matched healthy control subjects. Significantly increased blood lead (364%, P < 0.001) and urinary lead (176%, P < 0.001) levels were observed in automobile workers (study group) as compared to controls. Systolic blood pressure (5.32%,
P < 0.05) and diastolic blood pressure (5.87%, P < 0.05) were significantly increased in the automobile workers as compared to controls. The significantly decreased non-activated
erythrocyte δ-aminolevulinic acid dehydratase (δ-ALAD) (−18.51%, P < 0.01) and activated δ-ALAD (−13.29%, P < 0.05) levels were observed in automobile workers as compared to normal healthy control subjects. But the ratio of activated/non-activated
δ-ALAD was significantly increased (43.83%, P < 0.001) in automobile workers as compared to controls. Excretions of δ-aminolevulinic acid (83.78%, P < 0.001) and porphobilinogen (37%, P < 0.001) in urine were significantly increased in the study group as compared to the controls. In automobile workers heamoglobin
(−11.51%, P < 0.001), hematocrit (−4.06%, P < 0.05), mean corpuscle volume (−3.34%, P < 0.05), mean corpuscle hemoglobin (−5.66%, P < 0.01), mean corpuscle hemoglobin concentration (−7.67%, P < 0.001), red blood cell count (−14.6%, P < 0.001) were significantly decreased and total white blood cell count (11.44%, P < 0.05) increased as compared to the controls. The results of this study clearly indicate that the absorption of lead is
more in automobile workers and it affects on blood pressure, heme biosynthesis and hematological parameters observed in this
study group. 相似文献

With the emergence of Delta strains in many regions of China, population health issues have aroused great concern in many industries. Therefore, it is necessary to intervene in population health management through a variety of means. This paper establishes an economic intervention model of cognitive computing to evaluate the health of population health management innovation, track the health risks of the population and actively manage the relationship between population health. This paper establishes a health assessment model based on cognitive computing and uses a population health survey to evaluate the physical condition, illness, and life index of 64 citizens in this city before and after the economic intervention. The results of the study show that when economic dynamics test indicators are added to the prediction model of the post-test scores of economic intervention and health status, the explanatory power R2 of the cognitive computing model increased by 4.8% and 3.5%, respectively. The score (β=0.36, p <0.001), IPDT ( Inventory of Piaget's Developmental Tas) intervention score (β=0.15, p = 0.025) and migration score (β=0.18, p = 0.012) can significantly predict the post-economic intervention test score (R2=51.2%, p <0.001). The pre-test score on the health status test (β=0.48, p <0.001) and the IPDT intervention score (β=0.25, p = 0.014) can significantly predict the health status post-test score (R2=32.54%, p <0.001). 相似文献

Numerous lines of evidence implicate a role of myeloperoxidase (MPO) in the pathogenesis of cardiovascular disease (CVD).
It is a well accepted fact that patients with chronic kidney disease (CKD) are at an increased risk for CVD. MPO is a pro-oxidant
enzyme which could be involved in the increased susceptibility of these patients to CVD. Hence, the levels of plasma MPO was
determined in healthy controls as well as in patients with CKD [stratified with the level of their kidney failure as CKD stages
II–V (end stage renal disease)]. Plasma MPO was assayed by a spectrophotometric method. Serum urea and creatinine were estimated
on a clinical chemistry analyzer using standard laboratory procedures. The mean plasma MPO levels were significantly lower
with advancing stages of renal failure (P < 0.001). There was a positive correlation between MPO and GFR (r = +0.89, P < 0.001) and a negative correlation with urea (r = −0.85, P < 0.001) and creatinine (r = −0.82, P < 0.001). While an inverse association was observed between plasma MPO and urea in CKD patients, such an association was
not observed in control subjects (P = 0.43). In conclusion, the decline in plasma MPO levels may be due to the inhibitory effect of uraemic toxins on the enzyme. 相似文献

Markers of bone formation in serum include total and bone specific alkaline phosphatase, osteocalcin and Type 1 collagen carboxy
terminal extension peptide. Bone resorption can be assessed by measuring plasma tartarate resistant acid phosphtase and urinary
excretion of collagen degradation products: hydroxyproline, hydroxylysine glycosides and more recently the pyridinium crosslinks
and associated peptides. We compared the excretion of hydroxyproline in women of reproductive age group to those of menopausal
age group and found a significant difference in the two age groups. Urinary hydroxyproline was found to be significantly raised
in post menopausal women. Thus hydroxyproline maybe used as the earliest indicator in the prognostic assessment of postmenopausal
women of their risk of developing osteoporosis and fracture. 相似文献

Lead poisoning remains a major problem in India due to the lack of awareness of its ill effects among the clinical community.
Blood lead, δ-aminolevulinic acid dehydratase (δ-ALAD) and zinc protoporphyrin (ZPP) concentrations are widely used as biomarkers
for lead toxicity The present study was designed to determine the impact of chronic lead exposure on selected biological markers.
A total of 250 subjects, of both sexes, ranging in age from 20 to 70 years, were recruited. On the basis of BLLs, the subjects
were categorized into four groups: Group A (BLL: 0–10 μg/dl), Group B (BLL: 10–20 μg/dl). Group C (BLL: 20–30 μg/dl) and Group
D (BLL: 30–40 μg/dl) having BLLs of 3.60 ± 2.71 μg/dl, 15.21 ± 2.65 μg/dl, 26.82 ± 2.53 μg/dl and 36.38 ± 2.83 μg/dl, respectively.
Significant changes in biological markers due to elevated BLLs were noted. The relation of BLL and biological markers to demographic
characteristics such as sex, habits, diet and substances abuse (smoking effect) were also studied in the present investigation.
Males, urban population, non-vegetarians, and smokers had higher blood lead levels. δ-ALAD activity was found to be significantly
lower with increased BLL (P < 0.001), while the ZPP level was significantly higher with increased BLL (P < 0.001). Further, BLL showed a negative correlation with δ-ALAD (r = −0.425, P < 0.001, N = 250) and a positive correlations with ZPP (r = 0.669, P < 0.001, N = 250). Chronic lead exposure affects the prooxidant-antioxidant equilibrium leading to cellular oxidative stress. 相似文献

The correlation between antioxidant capacity and oxidative damage during aging has been reported in several tissues in different
species. Glutathione-S-transferases (GST) can metabolise endogenous and exogenous toxins and carcinogens by catalysing the
conjugation of diverse electrophiles with reduced glutathione (GSH). We observe a significant (P < 0.001) increase in plasma GST activity as a function of human age (r = 0.5675). A significant (P < 0.001) positive correlation (r = 0.8979) is observed between GST activity and total plasma antioxidant potential measured
as ferric reducing ability of the plasma (FRAP). GST activity and red cell intracellular GSH also show a significant positive
correlation (r = 0.7014). We hypothesize that the increased activity of plasma GST is a manifestation of increased generation
of ROS and a concomitant decrease in the level of plasma antioxidant capacity during aging. 相似文献

Introduction:
The aim of the study was to identify biomarkers of alteration in bone mineral density (BMD) in patients on haemodialysis (HD) and peritoneal dialysis (PD).Materials and methods:
In a cross-sectional, longitudinal study dual-energy X-ray absorptiometry scans were performed in 146 HD-patients and 28 PD-patients. Follow-up after 14 months (mean) was conducted in 73 patients. As potential biomarkers we investigated parathyroid hormone (PTH), 25-hydroxy vitamin-D, ionised calcium, albumin, phosphate, and total alkaline phosphatases (t-ALP).Results:
Both groups of dialysis patients had lower BMD in the femoral neck (BMDneck) (P < 0.001) and forearm (BMDforearm) (P < 0.001) compared to healthy controls, but comparable BMD in the lumbar spine (BMDspine). BMD did not differ between dialysis types, but patients ever-treated with glucocorticoids had significantly lower BMD, while patients with polycystic kidney disease had higher BMD. BMD correlated with body weight, actual age, age at initiation of dialysis, duration of dialysis and levels of PTH and t-ALP. However, t-ALP only remained associated with low BMDspine after adjusting for other factors (P = 0.001). In the follow-up study all patients had decreased BMD in all three locations, but only for the lumbar spine there was a significant association between BMD and the bone markers t-ALP (P = 0.009) and PTH (P = 0.013).Conclusions:
Both HD and PD patients have low BMD, and increased concentrations of t-ALP is associated BMDspine after adjustment, while PTH and t-ALP is associated with decrease in BMDspine over time. This substantiates the use of these biomarkers in both types of dialysis patients. 相似文献12.

The pathogenesis of idiopathic nephrotic syndrome is not completely understood. We postulate that cytokine gene polymorphisms
may influence susceptibility or clinical course in Idiopathic Nephrotic Syndrome. Polymorphisms of IL-4, IL-6, and TNF-α cytokines
were investigated in 150 children with Idiopathic Nephrotic Syndrome and 569 healthy controls by using polymerase chain reaction
and restriction fragment length polymorphism. On comparing patient with controls strong association were found for IL-6, TNF-α
and IL-4 at allelic level (IL-6-G174C (G vs. C): P = <0.001; OR = 6.33, TNF-α-G308A (G vs. A): P = <0.001; OR = 1.99, IL-4-C590T (C vs. T): P = 0.048; OR = 1.38). Further when SR group was compared with SS group significant association was found at genotypic level
in all the studied genetic polymorphisms. Studied cytokine gene polymorphisms may influence susceptibility to idiopathic nephrotic
syndrome and might affect steroid response in INS patients. 相似文献

Insulin resistance and the resultant hyperinsulinemia exacerbate the reproductive abnormalities of Polycystic Ovarian Syndrome
by increasing ovarian androgen productions and decreasing serum sex hormone binding globulin. The present study was conducted
to estimate serum insulin and testosterone level in 44 PCOS cases and 32 control patients. Simultaneously the role of metformin
(an insulin sensitizing agent) in modulating insulin resistance and serum androgen level was also analyzed. A significant
rise in serum insulin and testosterone (P < 0.001) was observed in cases in comparison to control. Fasting Plasma Glucose to insulin ratio, a marker of insulin resistance
revealed a significant fall in PCOS group. Follow up of cases with metformin for 3 months revealed a significant fall in serum
insulin (P < 0.05) with improvement in insulin resistance along with a nonsignificant fall in testosterone level. Serum insulin registered
a significant positive correlation (P < 0.05) with serum testosterone revealing its etiological association. Thus administration of drugs ameliorating insulin
levels is expected to provide new therapeutic modality for PCOS. 相似文献

The serum acid phosphatase (ACP) activity and Hemoglobin (Hb) levels were measured in malaria patients and nonmalarial fever
patients. The results were compared with normal healthy control subjects. ACP was significantly increased (P < 0.001) in all the malaria patients. ACP was significantly higher in Plasmodium falcifarum malaria and mixed malaria when compared to Plasmodium vivax malaria. Hb levels were significantly decreased in all the malaria patients which indicates that malaria parasite uses host
erythrocyte Hb as a major nutrient source. There is negative correlation(r = −0.478) between ACP and Hb in malaria patients, which is highly significant. These results suggest that the measurement
of ACP could be used as a marker for malaria. 相似文献

Indian ethnicity by itself is a strong risk factor for development of CAD in Indian postmenopausal women due to lower HDL
levels as compared to Whites and women of oriental origin. We evaluated and compared the short-term effects of menopause,
estrogen replacement therapy and combined estrogen and progestin replacement therapy on various atherogenic indices. 40 postmenopausal
women, both surgical and natural (20 each) were selected. 10 surgical postmenopausal women were given 0.625 mg conjugated
estrogens daily for 6 months and 10 natural postmenopausal women were given 0.625 mg conjugated estrogen with 2.5 mg medroxyprogesterone
acetate daily. 20 women were included in the control group and given placebo. Fasting venous blood samples were analyzed for
extended lipid profile and calculated atherogenic indices before starting the therapy and after 1,3 and 6 months. LDL and
Apolipoprotein B increased (p<0.05) and those of Apolipoprotein A1 and HDL decreased in the control groups. In both the study
groups levels of serum cholesterol and LDL decreased (p<0.05) and those of HDL and Apolipoprotein A1 increased (p<0.01). LDL/HDL,
Apo B/ApoA1, Total Cholesterol/HDL decreased significantly (p<0.05) in both the study groups compared to the control groups.
The effect of estrogen alone was more significant as compared to combination therapy. Log Triglycerides (TG)/HDL ratio showed
a decrease in women on estrogen alone but the difference was not significant. Our study confirms that short term HRT has a
favorable effect on atherogenic indices in Indian postmenopausal women. 相似文献

Plasma fibronectin (FN) levels in obese/overweight and non-obese pregnant women were evaluated as a possible risk factor for
preeclampsia. A total of one hundred and sixty three pregnant women attending antenatal clinic at University of Calabar Teaching
Hospital participated in the study and sixty non-pregnant women served as control. About 77 (47.24%) of the pregnant women
were followed up for any subsequent development of preeclampsia during the pregnancy. Fibronectin levels in plasma were measured
by ELISA assay and serum total protein, urea and creatinine were determined spectrophotometrically. The mean plasma FN concentration
of non-obese pregnant women in first trimester was lower than those of the non-pregnant women by 24%, but however, increased
to the non-pregnant level in second and third trimesters. Obese/overweight pregnant women had significantly (P < 0.05) higher values than non-obese pregnant women in second and third trimesters. FN in obese/overweight pregnant women
correlated positively with mean arterial blood pressure (MAP: r = 0.414, P = 0.04). About 28.57% of the pregnant women with FN above cut off point of 330 μg/ml at 18–24 weeks of gestation developed
preeclampsia. This value increased to 40.0% when only the obese/overweight women were considered. On analysis of both fibronectin
>330 μg/ml and MAP > 90, the predictive value increased to 66.7%. We therefore conclude that elevated FN may be regarded as
a risk factor of preeclampsia especially among the obese women. 相似文献

Cystatin C is an emerging parameter for the assessment of renal allograft function. The objective of the study was to compare
the efficacy of serum cystatin C (SCys) with the established parameter serum creatinine (SCr) in the assessment of renal function
in renal transplant recipients (RTR). The glomerular filtration rate (GFR) of 30 renal transplant patients and 29 control
subjects was determined using 99mTc Diethylene-triamine-penta-acetate (DTPA) method. SCr was measured using an automated Jaffe’s assay and SCys was measured
using latex particle enhanced turbidimetric immuno assay (PETIA). The modification of diet in renal disease (MDRD) formula
was used to calculate GFR from SCr, while the Le Bricon formula was used to derive GFR based on SCys. Statistical analysis
was performed using MedCalc software. SCr and SCys levels were significantly higher, while DTPA clearance was significantly
lower in RTR (P < 0.0001) when compared with controls. The correlation coefficient (r value) between calculated GFR based on MDRD method and DTPA clearance was 0.343 (P = 0.06) while the calculated GFR based on Le Bricon formula was 0.694 (P < 0.001). The results have shown that SCys is a better parameter than SCr in assessing renal function in RTR. The inclusion
of SCys as an additional parameter would certainly help in detection of even a marginal decline in renal function and also
in adjusting the dosage of immunosuppressive drugs. 相似文献

We recruited 59 individuals of known HIV serostatus after informed consent however, 44 were serodiscordant heterosexual partners
[serodiscordant seronegative (SSN group) and serodiscordant seropositive (SSP group)] while 15 were seronegative healthy individuals
(SNH). In the case–control study we choose to determine Malondialdehyde (MDA) concentration as a marker of lipid peroxidation
index (oxidative stress) spectrophotometrically and quantify HIV mRNA by Real Time-nucleic acid sequence based amplification
assay (RT-NASBA). Here our result show for the first time a high concentration of lipid peroxidation product (MDA, 116.6%)
with a significant (P < 0.05) increase in HIV serodiscordant seropositive subjects over their seronegative partners. However, Spearman rank correlation
statistics of SSP group showed a positive correlation value (P < 0.01, r = 0.89) between MDA and mRNA and a negative correlation between MDA and T-cell ratio (P < 0.01, r = 0.96).The study may strongly indicate a possible lipid peroxidation product threshold for predicting HIV infection and
progression in serodiscordant heterosexual partners. 相似文献

The present study was carried out to investigate the protective role of Triphala (a combination in equal proportions by weight
of fruit powder of Terminalia belerica, Terminalia chebula and Emblica officinalis) against 1,2-dimethylhydrazinedihydrochloride (DMH) induced Endoplasmic reticulum stress (ER stress) in mouse liver. An oral
dose of 3 mg/kg body wt in drinking water for 5 weeks significantly (P < 0.001) increased the levels of serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase
(SGPT), serum Alkaline phosphatase (ALP) and total bilirubin thus suggesting damage to mouse liver and biliary dysfunction.
The DMH administration invariably led to increase in the liver microsomal proteins of molecular weight of about 29 (ERp29)
and 53 kDa (ERp53) and decrease in the protein of molecular weight of 36 kDa (ERp36) thereby suggesting the interference of
DMH and its metabolites with normal protein biosynthesis and folding, in the reticular membranes of the liver cells thus developing
ER stress. Histological studies show necrosis, large sized hepatocytes with increased N:C ratio, aberrant mitotic figures
and prominent nucleoli in the liver of DMH treated mice. In animals fed 5% Triphala in diet (w/w) during DMH administration,
there was significant decrease in the above changes in the liver suggesting the suppression of DMH induced ER stress in liver.
Triphala significantly (P < 0.05) decreased lipid peroxidation and also the activity of lactate dehydrogenase (LDH) in mouse liver. It simultaneously
increased the level of reduced glutathione (GSH) and the activity of glutathione-S-transferase (GST) thereby suggesting that
it prevents peroxidative damage and also diverts the active metabolites (electrophiles) of DMH from their interactions with
critical cellular bio-molecules which could be responsible for its protective action against DMH. 相似文献
