Objective To explore the value of Toll-like receptor 2(TLR2) on the diagnosis of neonatal septicemia especially for the early diagnosis.Methods Twenty-two newborns with septicemia were divided into 2 groups according to the time of onset:early-onset group(n=12) and late-onset group(n=10).Another 14 non-infectious newborns were collected as control group.The TLR2 mRNA in peripheral blood was detected by real-time polymerase chain reaction,and mononuclear cells were isolated by the density gradient centrifuga-tion;the C reaction protein(CRP) was detected,and the co-relationship of the indexes was analyzed by Pearson correlation analysis.Results 1.The level of CRP in early-onset group were(157.89?32.96) ng?L-1,and(89.78?16.24) ng?L-1 in late-onset group,and there was significant difference between both groups(P=0.001);(6.91?1.20) ng?L-1 in control group,which was significantly lower than that in early-onset group and late-onset group(P=0.000,0.001).2.The expression of TLR2 mRNA in early-onset group and late-onset group was(57.38?10.72)?1012 copies?L-1and(32.74?4.65) ?1012 copies?L-1,which was significantly higher than that in control group[(4.12?0.68) ?1012 copies?L-1].3.CRP is positively correlated with TLR2 mRNA(C=0.972,P=0.000).Conclusions TLR2 expression is proven to be related to both the level of CRP and the stage of onset and may play a key role in the pathogenesis of neonatal septicemia.Detection for TLR2 may assist the earlier diagnose of atypical neonatal septicemia.

Objective To examine the relationship of body mass index (BMI) with levels of vitamin D,parathyroid hormone (PTH),and bone turnover markers among women in Shanghai area.Methods Altogether 810 Chinese women aged 45 year and older were enrolled to study the associations by multiple linear regression analyses.Bone mineral density was measured by a dual energy X-ray absorptiometry (Lunar,Prodigy,GE),Serum 25-hydroxyvitamin D [25 (OH) D],PTH,C-telopeptide of type Ⅰ collagen (CTX),osteocalcin (BGP),and bonespecific alkaline phosphatase (BSALP) were measured.Results (1) 25 (OH) D,BGP,BSALP,and CTX levels were significantly lower in obesity group than in control group ; PTH level was significantly higher in obesity group than in control group.(2) In multiple linear regression analyses,BMI was significantly associated with lower 25 (OH) D (β =-0.017,P =0.006),BGP (β =-0.077,P =0.019),and higher PTH (β =0.025,P =0.000).Conclusions (1) There were siginificant associations between higher BMI and lower 25 (OH) D among women in Shanghai.(2) Serum osteocalcin was associated not only with bone metabolism but also with energy metabolism.

Objective To investigate the expression of angiotensinⅡ (Ang Ⅱ ) and its type 1 receptor (AT1) in circulation, placenta and kidney of the rots preeclampsia. Methods Preedampsia rat model was developed by inhibitor of nitric oxide synthase (L-NAME). The systolic blood pressure (SBP), 24 h urine protein, hepatic and renal function were compared among the precelampsia group, the normal pregnant group and nonpregnant control group. The kidney tissue was observed by light microscopy. ELISA and radioimmunoassay were used to detect Ang Ⅱ in rat plasma and kidney homogenate respectively. Placental AT1 was measured by Westem blot. The level of kidney AT1 was evaluated by immunohistochemistry and Western blot. Results In preeclampsia rats, SBP and 24 h urine protein were significantly higher compared with control groups. Compared to normal pregnant group, plasma Ang Ⅱ of preeclampsia rats was much higher [(0.706±0.086) ng/L vs (0.540±0.085) ng/L, P＜0.05]; placental AT1 was increased by 46%(P＜ 0.05); kidney Ang Ⅱ was decreased signigicantly [(65.543±40.634) ng/g vs (165.543±33.078) ng/g, P＜0.05]. The expression of ATI in kidney of preeclampsia rats was reduced evidently,which was only 33% of normal pregnancy group and 59% of nonpregnant control greup,respeetively (P＜0.05). Conclusions In preeclampsia rat model, the circulating Ang Ⅱ is increased, the placental RAS isactivated, while the kidney BAS is suppressed. The underlying mechanism of proteinuria and kidney damage associated with this phenomenon in preeclampsia needs further research.

Objective To understand the situation of oxidative stress among diabetic nephropathy (DN) patients and observe the antioxidative effect of losartan at increasing dose in DN patients. Methods Thirty type 2 DN patients who neither smoked and nor took antioxidants were selected. The study began with an initial 4-6 weeks screening-treatment. Eligible patients then received losartan 50 mg/d daily for 8 weeks followed by losartan 100 mg/day daily for an additional 8 weeks. Blood glucose and blood pressure were closely monitored over the whole study period. All patients were followed up every other weeks, their 24-hour urine samples,fresh urine and venous blood sample were collected to measure urinary protein and creatinine excretion, urinary 8-OHdG, SOD, TAOC and MDA excretion , serum SOD, TAOC , MDA and other blood biochemistry parameters. Urinary 8-OHdG was determined by capillary electrophoresis and liquid phase chromatography. Results The total 24 hours urinary 8-OHdG excretion and the serum MDA concentration were higher than the normal values. The serum and urine SOD concentrations were lower than the normal values. There was an improvement in urinary 8-OHdG,serum and urine SOD, serum and urine MDA levels with losartan therapy. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d was more noticeable. Obvious decrease in 24-hour proteinuria on exposure to losartan was found, without severe adverse effect. Conclusions Oxidative stress damage is active in DN patients. Losartan has antioxidative effect on DN patients. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d is more marked, without increasing side effect. Losartan's antioxidative effect may be involved in its beneficial mechanisms on DN.

Objective To examine the association between vitamin D and alendronate response,and to investigate the proper vitamin D levels for the efficacy of alendronate treatment of osteoporosis.Methods In this retrospective study,559 post-menopausal women with osteoporosis were devided into two groups:non-responders and responders,based on the European Study of Forsteo (EUROFORS).Demographic and clinical data including mean 25-hydroxy vitamin D (25-OHD) levels between dual-energy X-ray absorptiometry (DEXA) scans were obtained.Mean 25-OHD levels were compared between responders and non-responders and multiple logistic regression analysis was performed to identify factors associated with non-response.Results There were 437 (75.5％) responsers to alendronate therapy and 142 (24.5％) non-responders.Responders with a mean serum 25-OHD level of (59.96 ±12.56) nmol/L,obtained a more favorable result than non-responders,whose serum 25-OHD level was (47.50 ±9.92) nmol/L (P＜0.01).25-OHD level was significantly associated with response.Conclusion Patients with a mean 25-OHD ≥50 nmol/L had a substantially greater likelihood of maintaining bisphosphonate response.

[Objective]To investigate associations between the functional polymorphisms of signal transducer and activator of transcription 4 (STAT4) gene and preeclampsia.[Methods]PCR-restriction fragment length polymorphism was used to genotype rs10181656 and rs16833431 local polymorphism in 228 preeclampsia cases and 179 normal controls.[Results](1)The frequencies of rs10181656C/G were 35.96%,46.37%in genotype C/C,47.81%,44.69%in genotype C/G and 16.23%,8.94%in genotype G/G between preeclampsia patients and normal controls. They reached statistical difference (P = 0.031). There was different distribution in two alleles(C and G)between preeclampsia patients and normal controls(P=0.009).(2)There was no different distribution in 3 genotypes(C/C,C/T,T/T)and 2 alleles(C and T)of rs16833431 C/T between preeclampsia patients and normal controls(P =0.508,0.461).[Conclusions]Functional polymorphisms of the rs10181656 locus could associate with the preeclampsia. The polymor-phisms of the rs16833431 locus could not associate with the preeclampsia.

Objective To investigate the effect of night shift time at midnight on sleep quality of nurses . Methods Pittsburgh sleep quality index (PSQI) and a self-designed questionnaire were used for the investigation among 459 nurses in a first class hospital in Fujian Province, analyzing the sleep quality of the nurses at night shift time at the time points of 0:00am,0:30am,1:00am and 1:30am during the midnight. Results The total score of nurses at night shift was (7.47 ±3.05). There were significant differences between the total scores at different time points (P<0.001). The comparisons between the time points of 0:00am and 0:30am,0:30am and 1:00am, 0:00am and 1:00am showed significant differences (P<0.017),and 0:00am<0:30am<1:00am. Conclusions As for night shift during midnight, the sleep quality for the night shift time 0:00am>0:30am>1:00am. The time points for night shift can vary with seasons and regions. The nurses should be aware of occupational prevention and develop a living habit. During night shift, the nurses should make an individualized plan.
