Objective To explore antiviral efficacy, safety and blocking of mother-to-infant transmission by administrating telbivudine in pregnant patients with chronic hepatitis B (CHB) throughout pregnancy. Methods Sixty-four cases of female patients were enrolled. The study participants were divided into the telbivudine treatment group (n = 31) and the control group (n = 33). Data were recorded from beginning of administration to ending pregnancy, as well as notation of any adverse reactions. The neonates and infants were evaluated in HBV infection, parameters of growth and development. Results The recovery rates of ALT, respectively, were 90.32% vs. 57.58% (P = 0.003), 93.55% vs. 62.50% (P = 0.003) at 24 weeks and ante partum and the HBVDNA-negative conversion rates, respectively, were 48.39% vs. 3.03% (P = 0.000), 83.87%vs. 6.06% (P = 0.000), 90.32% vs. 6.25% (P = 0.000) respectively, at 12, 24 weeks of pregnancy and at ante partum between the treatment and control groups. The HBsAg-positive and HBVDNA-positive rates of the infants, respectively, were 12.90% vs. 37.50% (P = 0.025) and 0 vs. 21.88% (P = 0.018) at birth, and respectively, were all 0 vs. 18.75% (P = 0.035) and 0 vs. 18.75% (P = 0.035) at 1, 6, 12 months old between the treatment and control groups. The treatment group showed lower incidence of intrauterine HBV infection (0 vs. 18.75%, P = 0.035). The gestational ages, fetal weights and Apgar scores were not significant different in the children born in the mothers from the two groups. Conclusions Telbivudine administration showed a good antiviral curative effect and effectively blocked mother-to-infant transmission in women with CHB. The treatment was safe and caused no obvious adverse reaction.

Objective To explore the value of DTI quantitative parameters in evaluating neurological function changes of acute traumatic spinal cord injury (TSCI)in rat models.Methods The modified Allen's dropping weight technique was used to establish TSCI rat models.Then the rats were divided into mild injury group,moderate injury group and severe injury group (each n=10).DTI examination and Basso-Beattie-Bresnahan (BBB) score were performed pre-TSCI and 0 h,6 h,24 h,3 day,7 day and 14 day post-TSCI,respectively.The BBB scores and DTI parameters,including FA,mean apparent diffusivity (MD),radial diffusivity (RD) and axial diffusivity (AD) were measured and compared among groups.The correlation between BBB scores and the parameters was evaluated.Results The differences of FA,MD and RD value were statistically significant among varying injury degree groups and different time points after TSCI (all P＜0.05).AD value had statistical difference among different time points (F=12.720,P＜0.001),whereas no difference was found among varying injury degree groups (F=0.469,P=0.630).FA and MD values decreased while RD increased 0 h post-TSCI.Then RD and MD increased continuously,whereas FA decreased continuously until 24 h post TSCI (all P＜0.05),and the parameters kept stable after 24 h post-TSCI (all P＞ 0.05).The BBB scores were lowest on 0 h post-TSCI,then maintained increasing (all P＜0.05).In addition,the BBB scores and MD values had good correlation (r=0.958,P＜ 0.01).Conclusion DTI can quantitatively evaluate function changes of TSCI in rat models.Moreover,treatment within 24 h post-TSCI might be recommended for TSCI therapy.

The community-friendly program " Online mobile payment of medical insurance" , launched by Guangzhou Municipal Medical Insurance Bureau, poses new challenges to hospital medical insurance management and information intelligence. To this end, the Second Affiliated Hospital of Guangzhou Medical University staged from January 2017 to March 2019 kept upgrading its IT system and built an intelligent monitoring system for medical insurance. These efforts prepared adequately for the medical insurance mobile payment, and explored a mode of medical insurance management, evolving from extensive management to standard and fine management.

Antipyretic-analgesics are currently one of the most prescribed drugs in children.The clinical application of antipyretic-analgesics for children in our country still have irrational phenomenon, which affects the therapeutic effect and even poses hidden dangers to the safety of children.In this paper, suggestions were put forward from the indications, dosage form/route, dosage suitability, pathophysiological characteristics of children with individual differences and drug interactions in the symptomatic treatment of febrile children, so as to provide reference for the general pharmacists when conducting prescription review.
