Objective: To investigate the compatible stability of ceftazidime and ormidazole chloride sodium injection with sequential intravenous dripping.Methods: The contents and the absorption curves of ceftazidime and ormidazole sodium chloride injection in the mixture were determined by UV.The appearance of the solution was observed and the pH value was determined.Results: With the quality ratio of ceftazidime to ormidazole at 1∶25, 1∶50 and 1∶100, the mixture color changed from light yellow to light pink in 40, 45 and 48 min, respectively, and gradually deepened with the extension of time.With the quality ratio of ormidazole to ceftazidime mixture at 1∶400, 1∶800 and 1∶1 600, the color was stable in 3 h.There were no evident changes in the appearance, pH, content and absorption curves.Conclusion: The solution containing ormidazole and ceftazidime might have changes in color.Clinical pharmacist suggests that ormidazole chloride sodium injection be given intravenously, and then sequentially followed by ceftazidime.

Objective To explore the efficacy of Cohen ureteric reimplantation for congenital malformation of vesicoureteral junction in children.Methods From February 2014 to August 2016,12 children with congenital monstrositas of vesicoureteral junction obstruction who were treated with pneumoeystoscopic Cohen ureteric reimplantation in Guizhou Provincial People's Hospital were selected.In these cases,8 males and 4 females,their ages ranged from 2 months past 1 year to 11 years,and the average age was 5.26 years.In the 12 patients,there were 6 cases with left vesicoureteral junction obstruction,and 1 case with right vesicoureteral junction obstruction,1 case with left ureter cyst and duplication of ureter ectopic opening,1 case with right duplex kidney and ureter cyst,1 case with right primary vesicoureteric reflux and left vesicoureteral junction obstruction,2 cases with bilateral primary vesicoureteric reflux and 1 case with ureter cyst.A foley catheter and ureteral stent was indwelled in each patient but no bladder fistula was made.All of the patients underwent pneumocystoscopic Cohen ureteric reimplantation.The stenting catheters were removed in 1-3 months after surgery.B ultrasonography was used to follow the degree of the dilatation of ureter and hydronephrosis.Urinalysis was conducted to detect the urinary tract infection.Intravenous urography examination was conducted to detect anastomotic stenosis.Voiding cystourethrography was performed to show ureteral reflux.Results All procedures were accomplished without conversion.The duration of operations ranged from 100 to 330 min (mean 207 min).All patients were followed up for 3 to 10 months,but no urinary tract infection and anastomotic obstruction occurred,and B ultrasonography showed that hydronephrosis or dilatation of ureter were improved in different degrees or disappeared.Two cases of ureteral reflux occurred in the early follow-up,and these cases recovered after being given symptomatic treatment.Conclusions The pneumocystoscopic Cohen ureteric reimplantation is a safe and effective option for congenital malformation of vesicoureteral junction in children.

Objective To analyze the prevalence of depression in early pregnancy, explore its possible influencing factors, and provide reference for mental health care during pregnancy. Methods A baseline survey of 9 193 early pregnant women recruited by the Chinese Pregnant Women Cohort Study (CPWCS) program was conducted. Edinburgh Postnatal Depression Scale was used to assess the depression symptoms in early pregnancy. The χ² test and multivariable logistic regression were used to analyze the influencing factors. Results The rate of depression in early pregnant women in CPWCS was 46.50%. Multivariate analysis showed that unplanned pregnancy (OR=1.23, 95%CI: 1.12~1.35, P<0.001), passive smoking (OR=1.28, 95%CI: 1.18~1.39, P<0.001), drinking (OR=1.35, 95%CI: 1.12~1.63, P=0.002) and consumption of carbonated or sugary beverages （OR=0.80, 95%CI: 0.73~0.88, P<0.001） were risk factors for depression during early pregnancy, while enough sleep (OR=0.71, 95%CI: 0.57~0.88, P=0.002), moderate-high level of physical activity (OR=0.87, 95%CI: 0.78~0.98, P=0.023), healthy intake of vegetables and fruits（OR=0.60, 95%CI: 0.51~0.70, P<0.001), animal foods（OR=0.82, 95%CI: 0.74~0.91, P<0.001） and milk and dairy products（OR=0.81, 95%CI: 0.72~0.90, P<0.001）were protective factors. Conclusion The rate of depression was high and it was affected by many factors. It is necessary to pay more attention to depression symptoms during early pregnancy and carry out targeted psychological health care during pregnancy.

Objective: To explore oral health care behavior and related factors among women in their 1^st trimester. Methods: Our analysis included 7 014 women in their 1^st trimester aged 16 years or above from the baseline survey of the Chinese Pregnant Women Cohort Study (CPWCS). Data on socio-demographic characteristics and oral health care behavior were collected using an electronic questionnaire. Multiple-factors Logistic regression was used to analyze factors associated with oral health care behavior. Results: The results revealed that 5 134 (73.20%), 2 482 (35.39%), and 1 046 (14.91%) pregnant women brushed their teeth twice a day or more, never had an oral examination, and used special oral care products for pregnant women, respectively. The frequency of brushing teeth and oral examination was positively associated with age and annual household income. Compared to unemployed pregnant women with rural registered residences and low education levels, highly educated and employed pregnant women with city registered residences had a higher frequency of brushing teeth and undergoing oral examination. Pregnant women with depressive symptoms had a lower frequency of brushing teeth (OR=0.73, 95% CI: 0.65-0.81), while those with medical insurance underwent more frequent oral examination (OR=1.19, 95% CI: 1.02-1.39). Compared to pregnant women who were unaware of the risk of gingivitis, those who believed gingivitis to be harmful to both themselves and their fetus had a higher frequency of brushing teeth and oral examination and were more likely to use special oral care products. Conclusion Most pregnant women did not pay attention to the need for oral examinations and special oral care products. Their oral health behavior was associated with socioeconomic status, depressive symptoms, and awareness of the importance of oral health. Therefore, oral health care before and during pregnancy was required to help them improve their self-care behavior.

Objective To understand the status of economic burden of maternal health care of pregnant women in China, and to discuss the equity and accessibility of maternal health care during pregnancy among different regions and populations. Methods A total of 9 193 women during early pregnancy were recruited from the Chinese Pregnant Women Cohort Study between July 25, 2017 and November 26, 2018. Information on general condition and economic burden of maternal health care was surveyed. SPSS 25.0 software was used for statistical analysis. Results The median direct medical cost of maternity check-ups for pregnant women was 400 CNY per visit, and the median cost of lost work was 360 CNY per visit. The analysis of the results showed that the median medical expense was highest in pre-pregnant women with BMI <18.5kg/m² (P=0.008). The median medical expense was higher in urban residents than rural residents (P<0.001). Families with fewer members had higher direct medical expenses (P<0.001, P_trend=0.003). The higher the socioeconomic status was, the higher the direct medical expense was (P<0.001, P_trend=0.003). The cost of lost work was lower in pregnant women with higher socioeconomic status (P=0.025, P_trend=0.017). In addition, the medical expense was highest in women living in the eastern part of China (P<0.001). The direct medical expenses (P=0.002) and lost-time expenses of pregnant women in the North were higher than those in the South (P=0.013). Conclusion The problem of equity and accessibility of maternal health care still existed. It is recommended that relevant departments further improve maternal health care services and build a diversified healthcare service system to ensure maternal and child health and promote eugenics.
