Cohort studies are important observational epidemiological studies. In this perspective, we briefly introduced several ongoing prospective cohort studies of cardiometabolic diseases in China and in the U. S. , which have shaped our current understanding of cardiometabolic diseases. We hope that this perspective could shed lights on the research of chronic diseases such as diabetes and cardiovascular diseases.

OBJECTIVE:To discuss the effect of Ethinylestradiol and cyproterone acetate tablet combined with metformin on ovulation induction of patients with polycystic ovarian syndrome(PCOS). METHODS:184 PCOS patients were randomly divided into control group(92 cases)and observation group(92 cases). Control group orally received 1 Ethinylestradiol and cyproterone ac-etate tablet in 5 d of menstruation,once a day,it stopped after 21 d,the next cycle of treatment was started on the 5th of with-drawal bleeding. Observation group additionally received 3 Metformin tablet,once a day,without drug withdrawal during menstrua-tion,and lasted for 3 menstrual cycles. After 3 menstrual cycles,all patients received ovulation induction treatment [(50-100 mg clomiphene was orally given from the 5th day of the 4th menstrual cycle,for 5 days,or 75-150 U postmenopausal gonadotropin by intramuscular injection,when the dominant follicle diameter was(19.0±2.0)mm,10 000 U human chorionic gonadotropin(HCG) was intramuscularly injected,the ovulation was continuously monitored and whether there was ovarian hyperstimulation syndrome (OHSS)was observed]. Body mass index(BMI),follicle estrogen(FSH),luteinizing hormone(LH),prolactin(PRL),estradiol (E2)and testosterone(T)before and after treatment,fasting plasma glucose(FPG),fasting insulin(FINS),insulin resistance in-dex(HOMA-IR),pregnancy rate,ovulation rate and the incidences of OHSS and adverse reactions in 2 groups were observed.RE-SULTS:Before treatment,there were no significant differences in the BMI,FSH,LH,PRL,E2,T,FPG,FINS and HOMA-IR between 2 groups(P>0.05). After treatment,BMI,LH,PRL,E2,T,FPG,FINS and HOMA-IR in observation group and LH, E2 and FINS in control group were significantly lower than before,and BMI,PRL,E2,T,FPG,FINS and HOMA-IR in observa-tion group were lower than control group,the differences were statistically significant(P<0.05). The pregnancy rate and ovulation rate in observation group was significantly higher than control group,the incidence of adverse reactions was significantly lower than control group,the differences were statistically significant (P<0.05). And there was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Ethinylestradiol and cyproterone acetate combined with metfor-min can effectively improve insulin resistance of POCS patients,recovery sex hormone secretion,promote ovulation and improve pregnancy rate,with good safety.

BACKGROUND:Pediatric knee dysfunction is a congenital malformation. Fusion and fixation can effectively eliminate pain, but no joint has active function. Total knee arthroplasty is a safe and effective method to relieve pain and to rebuild its function. With the continuous development of total knee arthroplasty, the type of knee prostheses is more. OBJECTIVE: To study the efficacy of different reconstruction methods for children with stunted knee arthroplasty. METHODS:120 knee stunted children were equaly divided into treatment group and control group depended on the reconstruction, and then al children were given the artificial knee replacement surgery and were completed by the same group of physicians. In the control group, stable fixed platform prosthesis was selected. In the treatment group, the non-limiting prosthetic-posterior cruciate ligament resection of low contact pressure rotating platform prosthesis was given. Operative time, blood loss, postoperative hospital stay, and complications were observed in both groups. Al patients were folowed up for 3 months. Knee function was assessed by Hospital for Special Surgery and American knee society knee score. Multivariate regression analysis was used to analyze the possible factors affecting Hospital for Special Surgery score during folow up. RESULTS AND CONCLUSION: No significant difference in operative time, blood loss and postoperative hospital stay was compared in both groups (P> 0.05). The postoperative overal incidences of inflammatory response, wound healing, periprosthetic infection, and joint stiff were significantly lower in the treatment group than in the control group (P < 0.05). At 3-month folowed-up, Hospital for Special Surgery and American knee society knee score clinical score and functional score were significantly higher in the treatment group than in the control group (P < 0.05). Hospital for Special Surgery score > 80 served as a standard. Multivariate regression analysis results showed that age, type of prosthesis, and varus deformity were the major independent risk factors for affecting joint replacement (P< 0.05). Results indicate that knee arthroplasty for knee dysfunction obtained good prognostic effect. Simultaneously, the non-limiting application of prosthetic reconstruction can effectively reduce postoperative complications and improve knee function.

Objective To investigate the effect of different doses of microbe?derived antioxidant on sleep and antioxidant ability in mice. Methods Sixty male Kunming mice with similar body weight were randomly divided into 4 groups. The control group received normal saline, and the experimental groups received microbe?derived antioxidant in a dose of 0?5 g/kg bw, 1?0 g/kg bw or 1?5 g/kg bw once per day, respectively. The experiment period was 30 days. At the end of experiment, the mice of each group were intraperitoneally injected sodium pentobarbital to induce sleep. The mice fall sleep was judged by righting reflex. After the test of sleep, blood was taken for detection of serum antioxidant ability. Results Compared with the low dose and high dose groups, the middle dose group showed a significantly prolonged sodium pentobarbital?induced sleeping time (P<0?05). Compared with the control group, low and high dose groups, the middle dose group had highly significantly increased GSH?Px activity ( P <0?01 ) and significantly increased content of SOD. Under these conditions, the middle dose group reduced both the contents of MDA and 8?ISO?PGF2α ( P<0?05 ) compared with the control group. Conclusions Our results suggest that microbe?derived antioxidant exerts effect on sleep and antioxidant ability in rats. Supplement of 1?0 g/kg bw/d shows the most significant effects.
