RESUMO
Objective: To assess the health status and health service utilization of children born to syphilis infected mothers during pregnancy, in order to prevent mother-to-child transmission of syphilis to the newborns. Methods: Women with maternal syphilis were studied by trained researchers via phone calls, in Shanghai during 2014-2015. Data related to demographics, status of infection and health care, utilization by both mothers and their children were collected through specifically designed questionnaires. Non-parametric tests including chi-square were used to assess the health status and health service utilization of children born to mothers with different demographic and socioeconomic characteristics. Results: A total of 495 children born to mothers with maternal syphilis were recruited from 1 000 syphilis infected parturient women. A total of 61 out of the 495 children were diagnosed as having congenital syphilis (57 children were diagnosed at birth and another 4 were diagnosed during the follow-up period). Children born to women who received syphilis treatment during pregnancy were at lower risk on congenital syphilis (χ(2)=7.214, P=0.027). 37.8% of the children were reported to have had different illnesses in the past three months, mainly involving upper respiratory infections (32.3%) or diarrhea (3.6%). Children diagnosed with congenital syphilis showed a higher prevalence of different kinds of diseases, compared to those without congenital syphilis (47.5% vs. 36.6%). 81.6% of the children had received regular child health care services. Subjects with the following factors as: being immigrant, with lower education, unemployed, unmarried and multipara, were related to the less use of regular child healthcare services. Only 39.7% of the parents would inform the care-takers about the risk of congenital syphilis infection of their own children at the child health care centers. Mothers with residency of Shanghai, having higher education level and employed, were less willing to inform doctors about the risk of congenital syphilis infection of their children. Conclusions: Loss to follow-up among children born to syphilis infected pregnant women remained a serious problem. Few parents would be willing to inform the healthcare takers that their children are at risk of syphilis, when receiving child health care services at the centers. It was necessary to integrate the congenital syphilis follow-up programs into the routine child care services so as to timely diagnose and treat the patients with congenital syphilis.

Objective: To identify problems and demands for antenatal care (ANC) among pregnant women in different trimesters of pregnancy in Shanghai for optimizing ANC service during the epidemic of COVID-19. Method: s Organized by maternal and child health care institute in the 16 districts of Shanghai, a cross sectional study was conducted among pregnant women who came to pregnancy registration in the community health centers or attended ANC in midwifery hospitals from February 7 to February 12, 2020. Consented participating women completed a semi-structured online questionnaire voluntarily. Data was analyzed using frequency,chi-square test and scoring. Result: s A total of 2 002 valid questionnaires were collected from 183 community health centers and 67 midwifery hospitals. About 94.6%(1 894/2 002) of the pregnant women worried about being infected during the COVID-19 epidemic, and 14.7% (294/2 002) demanded for psychological consultation. Time-lapse appointments for ANC were requested by 87.7% (1 756/2 002) of the participants for avoiding presenting themselves in people-density places. Compared with other pregnancy trimesters, pregnant women in the second trimester were more willing to reduce the frequency of ANC (35.2% versus 39.5% versus 48.1%, P<0.01). Compared with multiparas, primiparas were more willing to have online consultation and guidance (49.2% versus 63.8%, P<0.01). Regarding the needs for health knowledge on COVID-19, personal protection against 2019 novel coronavirus (2019-nCoV) was the most concerned for pregnant women, and 71.0% (1 421/2 002) of them preferred to obtain knowledge through health applications, official Weibo and WeChat. Conclusions: Pregnant women in Shanghai critically concern about the risk of 2019-nCoV infections, and highly demand knowledge and measures on prevention and protection from COVID-19. They ask for having time-lapse appointments for ANC and online access to health information and services. Maternal and child care institutes should understand the demands of pregnant women, optimize the means of ANC service, and provide tailored and accessible health education and service for the safety of mother and child.

The pharmacokinetics and pharmacodynamics of changrolin (CRL) were studied in 7 dogs with arrhythmia induced by coronary artery ligature. The ECG and the percentage of reduction ratio of ventricular premature were used to evaluate the effect of CRL, and an HPLC method was used to determine the serum drug concentration. A pharmacokinetic program was used to fit concentration-time (C-T) data and a combined pharmacokinetic-pharmacodynamic model was used to analyze effect-time (E-T) data in individual dogs. After infusion with CRL 83.33 micrograms.kg-1.min-1 for 60 min, it was found that K10, T1/2, Vd, Cl and Ce were 0.0087 min-1, 78.03 min, 40.55 ml.kg-1, 0.42 ml.kg-1.min-1, and 2.01 micrograms.ml-1, respectively.
