Objective:To investigate the prevalences of overweight and obesity and its relationship with the risk factors of cardiovascular diseases among physical examination population in Nanjing Drum Tower Hospital.Methods:A retrospective analysis was performed on 384 061 adults aged 20 years and older. Age- and sex-standardized prevalences of overweight and obesity were calculated using Chinese census data in 2010. Multivariate logistic regression analysis was used to assess the associations of overweight and obesity with the risk factors of cardiovascular diseases.Results:The age-standardized prevalences of overweight and obesity were 42.8% and 13.2% in men and 23.9% and 6.6% in women. A gradually increasing trend was observed in the prevalences of overweight and obesity from 2008 to 2016, especially in subjects aged 20-39 years. Overweight and obesity were significantly associated with increased risks of dyslipidemia, diabetes mellitus, hypertension, and hyperuricemia. These associations were found to be the strongest among subjects aged 20-39 years, which became weaker along with the increasing of age. The OR(95% CI) of dyslipidemia, diabetes mellitus, hypertension, and hyperuricemia were 4.23(4.01-4.47), 3.70(2.97-4.60), 6.19(5.76-6.64), and 3.66(3.45-3.88) in obese men aged 20-39 years, while 5.29(4.63-6.04), 6.38(3.86-10.55), 9.36(7.86-11.13), and 6.65(5.70-7.74) in obese women aged 20-39 years, respectively. Conclusion:The increasing trend in the prevalence of overweight and obesity is a risk factor for cardiovascular diseases in Nanjing adults, especially in individuals aged 20-39 years.

Obj ective To observe and analyze the curative effect of large dose shock therapy of calcitriol on the treatment of the patients with end-stage renal disease (ESRD)complicated with secondary hyperparathyroidism (SHPT).Methods 60 patients with ESRD complicated with mod-erate or severe SHPT were selected as the research obj ects and randomly divided into the observation group and the control group,30 cases in each group.The patients in the observation group were treated with large dose shock therapy of calcitriol,while the patients in the control group were treated with routine dose therapy of calcitriol.The serum levels of calcium,phosphorus,parathy-roid hormone (PTH),hemoglobin (Hb)and hematocrit (HCT)of the patients in the two groups before and after the treatment were detected.The improvements of the skin itching of the patients were evaluated.Results The serum PTH level and the serum phosphorus levels of the patients in the two groups after the treatment were significantly lower than those before the treatment (P <0 .05 ),and the serum PTH level and the serum phosphorus levels of the patients in the observation group after the treatment were significantly lower than those in the control group (P<0 .05 ).The serum calcium level of the patients in the two groups after the treatment were significantly higher than that before the treatment (P<0 .0 5 ),and the serum calcium level of the patients in the observation group after the treatment were significantly higher than that in the control group (P<0 .05 ).The clinical efficacy in improving skin itching of the patients in the two groups were 90%and 40%,the clinical efficiency of the observation group was significantly higher than that of the control group (P<0 .05 ).Meanwhile,the proportion of the patients with the curative ef-fect of“significant”in the observation group was significantly higher than that in control group (P<0 .05 ).Hb and HCT levels of the patients in the two groups after the treatment were signif-icantly higher than those before the treatment (P<0 .05 ),and Hb and HCT levels of the patients in the observation group after the treatment were significantly higher than those in the control group (P<0 .05 ).Conclusion Application of large doses shock therapy of calcitriol in the treat-ment of ESRD complicated with SHPT can rectify the imbalance calcium and phosphorus metabolism of the patients rapidly,reduced the serum PTH level of the patients significantly,and relieve significantly the symptoms of skin itching or anemia of the patients.

Sometimes crystals cannot diffract X-rays beyond 3.0 Å resolution due to the intrinsic flexibility associated with the protein. Low resolution diffraction data not only pose a challenge to structure determination, but also hamper interpretation of mechanistic details. Crystals of a 25.6 kDa non-Pfam, hypothetical protein, PF2046, diffracted X-rays to 3.38 Å resolution. A combination of Se-Met derived heavy atom positions with multiple cycles of B-factor sharpening, multi-crystal averaging, restrained refinement followed by manual inspection of electron density and model building resulted in a final model with a R value of 23.5 (R(free)= 24.7). The asymmetric unit was large and consisted of six molecules arranged as a homodimer of trimers. Analysis of the structure revealed the presence of a RNA binding domain suggesting a role for PF2046 in the processing of nucleic acids.

Objective To determine the association of subclinical hypothyroidism (SCH) with body composition (measured by body impedance analysis) and insulin resistance (IR) in overweight/obese patients with polycystic ovary syndrome (PCOS).Methods A retrospective analysis was conducted of the clinical records of 109 overweight or obese [body mass index (BMI) ≥ 24 kg/m2] PCOS patients who visited the Department of Endocrinology and Fertility Center of Nanjing Drum Tower Hospital between April 2013 and April 2016 for menstrual disorder or infertility and were referred to receive weight management.24 of the patients had SCH,and 85 had euthyroid (EU).We determined the body composition of the patients with Biospace Inbody 720 body composition analyzer,measured the patients' serum lipid profiles,conducted in each patient the 75 g oral glucose tolerance test and the insulin release test,and calculated the homeostasis model assessment of insulin resistance (HO-MA-IR) indices.Results Patients with SCH and autoimmune thyroiditis (AIT) accounted for 22.02％ and 24.36％ of the total.The obesity level [(145.19±13.75)％ vs.(153.31±18.15)％,t=-2.032,P=0.045],VFA [(132.48±20.85) cm2vs.(147.35±24.26) cm2,t=-2.730,P=0.007],body fat (BF) [(31.91±5.88) kgvs.(35.43±6.89) kg,t=-2.274,P=0.025],body fat percentage (BFP) [(40.92±3.701)％ vs.(43.07±4.26)％,t=-2.241,P=0.027],body mass index (BMI) [(30.49±2.88) kg/m2 vs.(32.19±3.81) kg/m2,t=-2.026,P=0.045] and waist circumference (WC) [(98.34±7.13) cm vs.(102.86±8.74) cm,t=-2.324,P=0.022] of SCH group were significantly lower than those of euthyroid,with significant statistical difference.The levels of serum thyroid hormone (TSH) in patients with EU were positively correlated with the degree of obesity,the BF,the BFP,the BMI and the hip circumference (P=0.019,0.042,0.005,0.019,0.039),but not with the VFA (t=1.797,P=0.076).There were no statistically significant differences (P＞ 0.05) between patients with SCH and those with EU in their HOMA-IR indices,insulin levels,blood glucose,blood lipid,and ratio of IR (defined as HOMA-IR ≥2.69).Conclusions Obesity related body composition parameters were lower in PCOS patients with SCH than in those with EU.However,there was no significant difference between the two groups in blood lipid level and the ratio of IR.TSH levels in the EU group were correlated with the BMI and the BFP,but not with the VFA.A larger sample is needed to identify how and why thyroid hormones may affect the body composition and glycolipid metabolism of females with PCOS.

ObjectiveTo investigate the mechanism of Biejiajian Wan in the intervention of primary liver cancer based on long non-coding RNA SNHG5 （lncRNA SNHG5）/micro RNA-26a-5p （miRNA-26a-5p）/glycogen synthase kinase-3β （GSK-3β） signal axis. MethodDouble luciferase reporting assay was used to verify the targeted interaction between lncRNA SNHG5 and miRNA-26a-5p， miRNA-26a-5p， and GSK-3β in HepG2 cells. Nude-mouse transplanted tumor model of human HepG2 were established and randomly divided into model group， Biejiajian Wan low-dose group （0.5 g·kg^-1）， medium-dose group （1.0 g·kg^-1）， and high-dose group （2.0 g·kg^-1）， and sorafenib group （100 mg·kg^-1）， with 10 mice in each group. The mice were given intragastric administration of normal saline or drug for 28 days， and the tumor volume was measured at different time. Hematoxylin-eosin （HE） staining was used to observe the histological changes of tumors. The nucleic acid levels of lncRNA SNHG5， miRNA-26a-5p， GSK-3β， and β-catenin mPNA in tumor tissue were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. The protein expression levels of GSK-3β and β-catenin in tumor tissue were detected by western blot. ResultCompared with the SNHG5-WT （wild type） + miRNA NC （negative control） group， the relative luciferase activities of the SNHG5-WT + miRNA-26a-5p mimic group were decreased （P<0.05）. Compared with the GSK-3β-WT + miRNA NC group， the relative luciferase activity of the GSK-3β-WT + miRNA-26a-5p mimic group was decreased （P<0.05）. Compared with the model group， the tumor volume of Biejiajian Wan low-dose， medium-dose， and high-dose groups was significantly decreased （P<0.05， P<0.01）. Compared with the model group， the cells in the tumor tissue of nude mice in each dose group of Biejiajian Wan were sparsely arranged with necrocytosis， which showed concentration-dependent changes. Compared with the model group， the expression levels of lncRNA SNHG5， GSK-3β， and β-catenin were decreased （P<0.05， P<0.01）， while the expression of miRNA-26a-5p was increased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. Compared with the model group， the protein expression levels of GSK-3β and β-catenin were decreased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. ConclusionBiejiajian Wan may affect the necrosis of liver cancer cells through lncRNA SNHG5/miRNA-26a-5p/GSK-3β signal axis and thus play an anti-tumor role. This research will provide more theoretical basis for the clinical application of Biejiajian Wan.
