OBJECTIVEGuanxin II is a famous modern formula of traditional Chinese medicine. Guanxin II after myocardial infarction (MI) has been shown to have beneficial effects on cardiac anatomy and function. The purpose of this study was to examine the effects of Guanxin 1I on cardiac protein expression after MI.

METHODRats were randomized into 3 groups, sham, model and treating groups. Model and treating groups were fed with Guanxin II and sham group was fed with water for 10 days before MI. MI operation is to ligate left coronary artery. 24 hours after MI, myocardial protein expression of junctional zone was assessed with 2D gel electrophoresis and mass spectra analysis.

RESULTGuanxin II was found to be able to improve myocardial protein expression, especially 11 proteins. These proteins are mainly involved in suppressing changes of cell shape and structure and energy metabolism.

CONCLUSIONGuanxin II after MI affected myocardial protein expression. Further experiments of larger research extent should be done to receive more results.

Objective Through the detection of the levels of serum betatrophin,anthropometric and biochemical indices,to determine the alteration of betatrophin levels in patients with polycystic ovary syndrome (PCOS) and the relationship between betatrophin levels and metabolic indexes such as 25-hydroxy vitamin D3 [25 (OH) D3].Methods The study group was composed of 24 women with PCOS and 20 age-natched healthy women as controls.Following general physical examination of the subjects,anthropometrie measurements were performed (height,weight,waist circumference,hip circumference).Body mass index (BMI) and waist-hip ratio were calculated;25 (OH) D3,Ca2+,fasting blood glucose,fasting insulin,triglycerides,high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C) were also measured and homeostasis model assessment of insulin resistance (HOMA-IR) were evaluated in all subjects.Serum betatrophin levels were examined with an enzyme-linked immunosorbent assay (ELISA).Using independent sample T test to compare the differences between groups,the linear correlation analysis was performed to study the correlation of betatrophin with anthropometric and biochemical indices,the influencing factors of betatrophin were analyzed by multiple linear regression.Results Circulating betatrophin levels [(0.341±0.034) ng/ml vs.(0.810±0.162) ng/ml,t=4.271,P＜0.001] and HDL-C [(1.014±0.321) mmol/L vs.(1.419±0.287) mmol/L,t=2.218,P＜0.05] significantly decreased in women with PCOS compared with controls,and BMI [(27.691±4.392) kg/m2 vs.(23.310±4.781) kg/m2,t=-2.073,P＜0.05],fasting blood glucose [(5.950±0.411) mmol/L vs.(4.883±0.314) mmol/L,t=-2.142,P＜ 0.05],HOMA-IR [(4.946 ± 0.741) vs.(3.387± 0.397),t=-2.493,P＜0.05],triglycerides [(1.510± 0.848) mmol/L vs.(1.037±0.402) mmol/L,t=-2.223,P＜0.05],LDL-C [(3.431±0.479) mmol/L vs.(2.396±0.435) mmol/L,t=-2.433,P＜0.05] were obviously increased.Moreover,there was a postive correlation between betatrophin and HOMA-IR (r=0.425,P＜0.05) as well as 25(OH)D3 (r=0.577,P＜0.05) and Ca2+ (r=0.448,P＜0.05),while the betatrophin was negatively related to BMI (r=-0.451,P＜0.05),triglycerides (r=-0.454,P＜0.05),LDL-C (r=-0.551,P＜0.05).Circulating betatrophin levels were higher when 25 (OH) D3 levels were beyond 35 nmol/L in PCOS patients [(0.539±0.092) ng/ml vs.(0.199±0.031) ng/ml,t=3.072,P＜0.001],and the multiple linear regression analysis showed that the main factors affecting the levels of betatrophin were BMI (OR=-0.260),HOMA-IR (OR=0.218),25(OH)D3 (OR=0.238),and glycerol (OR=-0.162).Conclusion It is speculated that betatrophin may be a valuable predictive factor of PCOS because betatrophin is closely associated with insulin resistance,lipid metabolism disorders and the lack of 25-hydroxy vitamin D3 in PCOS patients.

OBJECTIVETo investigate the regulatory mechanism of parathyroid hormone-related protein (PTHrP) in proliferation and differentiation of chondrocytes of condyle in fetal mouse.

METHODSChondrocytes of condyle in fetal mouse were separated and cultured in vitro, the influence of PTHrP on proliferation and differentiation was observed.

RESULTSAfter two weeks' culture in 0.01 nmol/L, 0.1 nmol/L, 1 nmol/L, 10 nmol/L human PTHrP, there was significant difference in the number of cartilage nodule formed between experiment group and control group (P<0.05), and there was no significant difference in 0.01 nmol/L group (P>0.05). Alkaline phosphatase (ALP) activity was significantly intensified in experiment group and control group (P<0.05). Meanwhile, it was found that this function of promotion was lessened after anti-PTHR antibody used.

CONCLUSIONIt can be seen that PTHrP, via its receptor, can promote proliferation and differentiation of chondrocytes of condyle, which resemble its modulation mechanism in epiphyseal growth plate cartilage intramembrane in mandibule.

Objective:To investigate the relationship between thyroid stimulating hormone (TSH) level and thyroid peroxidase antibody (TPOAb) status in the first trimester on pregnancy outcomes.Methods:A total of 2 095 pregnant women with complete clinical data from department of pregnancy endocrinology or department of obstetrics in Dongying People′s Hospital from January 1, 2018 to November 31, 2019.According to the TSH level detected before 12 + 6 weeks of gestation, all pregnant women were divided into normal TSH (0.1 μIU/ml≤TSH< 2.5 μIU/ml), high TSH (2.5 μIU/ml≤TSH≤4.0 μIU/ml), sub-clinical hypothyroidism during gestation (4.0 μIU/ml0.05). Multivariate logistic regression analysis of gestational diabetes mellitus and preterm delivery showed that the risk of gestational diabetes mellitus was significantly increased in group F compared with the control group. Age, gestational status, and TPOAb positivity were risk factors for gestational diabetes. The risk of premature birth in group D, group E and group F was higher than that in the control group [odds ratio ( OR)>1]. Age and TPOAb positivity were risk factors for preterm delivery in pregnant women ( OR>1, P<0.05). Conclusions:TPOAb positive in early pregnancy combined with subclinical hypothyroidism in pregnancy will increase the risk of gestational diabetes, while TPOAb positive in early pregnancy combined with TSH on the high side or subclinical hypothyroidism in pregnancy will increase the risk of premature delivery, so the management of such pregnant women should be strengthened and active treatment should be given if necessary.
