Objective To observe the effect of the modified Yulin Decoction on improving the living quality of patients with yang-deficiency of the spleen and kidney of premature ovarian failure. Methods One hundred and twenty-seven patients were divided into experimental group (80) and control group (47) by non-randomized noninferiority comparative study. The experimental group was treated with modified Yulin Decoction daily orally once a day. The control group was treated with oral estradiol valerate and progesterone cycle. Two groups received continuous medication for 21 d, and treatment interval was 5 d. Three cycles of treatment were set as one course, and treated for 2 courses. The SF-36 scale was used to calculate the total scores and scores of eight dimensions before and after treatment. Results Before treatment, there was no significant difference (P>0.05) in the scores of SF-36 dimensions (except somatic pain) and total score between the two groups. Compared with before treatment, the score and total score of SF-36 in the experimental group increased (P<0.05, P<0.01). The mental health score of the control group was higher than that of before treatment (P<0.05, P<0.01). After treatment, there was statistical significance in the two dimensions of vitality and mental health in the two groups (P<0.05). There were significant differences (P<0.01) in the total score and scores of SF-36 physiological function, physical pain, general health, vigor, social function, emotional function and mental health between the two groups. Conclusion Modified Yulin Decoction can improve the living quality of patients with yang-deficiency of the spleen and kidney of premature ovarian failure.

Objective To investigate the prevalence and associated factors of fecal incontinence (FI) and urinary incontinence (UI) in postpartum Chinese women.Methods Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within six months after delivery.Multi-variant Logistic analysis was applied for relation between delivery mode and FI or UI.Results (1) Two thousand and twelve postpartum women were admitted into this study,among which 14 (0.7％) had FI within 6 months after delivery.Logistic regression analysis showed that FI was significantly associated with forceps delivery (OR =20.09,95 ％ CI:3.64-110.90,P =0.000),and mediolateral episiotomy (OR=6.11,95％ CI:1.29-28.80,P=0.024).(2) Among the 2012 women,the prevalence of UI,stress urinary incontinence (SUI),urgent urinary incontinence (UUI)and mixed urinary incontinence (MUD was 10.04％ (n=202),8.15％ (n=164),0.94％ (n=19)and 0.94 ％ (n =19),respectively.Logistic regression analysis found that SUI prevalence was related to maternal age (OR =1.07,95％ CI:1.04-1.11,P =0.000),maternal weight before delivery (OR=1.04,95％ CI:1.02-1.06,P=0.001),neonatal head circumference (OR=1.20,95％ CI:1.05-1.39,P =0.010),mediolateral episiotomy (OR =4.96,95 ％ CI:3.05-8.07,P =0.0005 ),spontaneous vaginal delivery (OR=5.22,95％ CI:2.53-10.76,P=0.000) and forceps delivery (OR=9.20,95％ CI:4.07-20.79,P=0.000).UUI was related to maternal weight before delivery (OR=1.51,95％ CI:1.12-2.05,P=0.008).MUI was related to maternal weight before delivery (OR=1.06,95％ CI:1.00-1.11,P=0.049),duration of second stage of labor (OR=1.01,95％ CI:1.00-1.03,P =0.010),mediolateral episiotomy (OR =7.76,95％ CI:1.42-42.52,P=0.017) and forceps delivery (OR=15.21,95％ CI:1.61-143.44,P=0.018).(3) The prevalence of SUI was higher at 4 days and 42 days after delivery (7.95％ and 9.10％).Conclusions (1) F1 and UI prevalence is lower in this study than in other reports.(2) Vaginal delivery is a risk factor for women's FI and UI,especially forceps delivery and mediolateral episiotomy.(3) Maternal age,pre-delivery weight,newborn head circumference,spontaneous vaginal delivery,forceps delivery and mediolateral episiotomy might increase the risk of UI.

Radial-cephalic arteriovenous fistula (RCAVF) is considered the first choice for hemodialysis vascular access because of its high patency rate and less complications.But up to 50％ of the fistula can not mature.This is mainly due to persistent low blood flow or difficulty in cannulation can not lead to adequate hemodialysis.Inflow or outflow stenosis,anastomotic stenosis,exceedingly deep location of the vein,flow diversion into accessory veins are the common causes of impaired maturation.In addition,thrombosis is a common of stenosis.Preoperative assessment by physical examination and ultrasound examination of blood vessels,select the appropriate blood vessels for the fistula is of great significance.Choose the appropriate treatment for the cause of maturation disorders.Postoperative aspirin is widely used to prevent thrombosis and reduce the occurrence of stenosis;Surgery has the advantage of bypassing the damaged area but creating a new stoma;in recent years,endovascular technique because of its characteristics of minimally invasive in most of the time is the first choice.In this paper,the definition,etiology,diagnosis and treatment of fistula maturation disorder are reviewed.

Objective: To investigate the effect of diabetes on the intensity of sarcoplasmic reticulum Ca2+-ATPase (SERCA2a)-SUMOylation and SERCA2a activity of myocardium in experimental rats.
Methods: The 8 weeks old SD rats were divided into 2 groups, Diabetic group, with diet-induced type 2 diabetic rats and Control group, with normal rats. The systolic and diastolic cardiac functions were evaluated by echocardiography and left ventricular pressure measurement. The intensity of SERCA2a-SUMOylation was examined by co-immunoprecipitation and SUMOylation kit.
Results: Compared with Control group, Diabetic group had decreased systolic and diastolic cardiac functions, especially for diastolic function;decreased SERCA2a protein expression and intensity of SUMOylation;decreased SUMOylation E2 (Ubc9 ) protein expression. The protein levels of SUMO1, SAE1 and SAE2 were similar between 2 groups.
Conclusion: The intensity of SERCA2a-SUMOylation and Ubc9 decreased in diabetic myocardium which implies that SERCA2a-SUMOylation and Ubc9 were closely related to the damage of diabetic myocardium in experimental rats.

Objective: To analyze the epidemiological characteristics of latent syphilis in Yancheng City from 2016 to 2020, so as to provide insights into syphilis control. Methods: All reported cases with latent syphilis in Yancheng City from 2016 to 2020 was collected from the Communicable Disease Report System of China Disease Prevention and Control Information System, and the prevalence of latent syphilis was estimated and standardized by the seventh population census data in Yancheng City. The trends in the incidence of latent syphilis were evaluated using annual percent change (APC), and the temporal, regional and human distributions of latent syphilis patients were descriptively analyzed. In addition, the spatial clusters of latent syphilis incidence were identified using spatial autocorrelation analysis. Results: A total of 7 790 cases with latent syphilis were reported in Yancheng City from 2016 to 2020, and the standardized incidence of latent syphilis increased from 15.35/105 in 2016 to 28.70/105 in 2020 (APC=17.54%, t=5.357, P=0.013). Latent syphilis cases were reported in each month, and no obvious seasonable characteristics were seen. During the period from 2017 to 2020, the highest incidence of latent syphilis was seen in residents at ages of 70 to 79 years, with incidence rates of 41.71/105, 43.04/105, 75.79/105 and 72.94/105, respectively, and most cases were farmers (4 711 cases, 60.47%). The three highest incidence of latent syphilis was reported in Funing County (191.40/105), Tinghu District (137.13/105) and Yandu District (126.23/105). There was a positive spatial correlation of latent syphilis incidence in Yancheng City from 2016 to 2020 (Moran's I=0.23, Z=4.457, P=0.001), and two high-high clusters were identified in 14 townships (streets) of Funing County, Binhai County, Tinghu District, Sheyang County and Yandu District and 3 low-low clusters in 7 townships (streets) in Jianhu County, Tinghu District, Dongtai City and Sheyang County. Conclusions The incidence of latent syphilis appeared a tendency towards a rise, and there were remarkable spatial clusters identified in latent syphilis incidence in Yancheng City from 2016 to 2020. The elderly people and farmers are at high risk of latent syphilis.
