中华医学杂志(英文版) 1993年第3期106卷 215-215页

作者： Bao Xiu-lan yu ren-jie Li Zhuo-suan Department of Pediatrics Peking Union Medical College Hospital Beijing 100730 Neonatal Behavioral Neurological Study Coordinating Group

From January 1989 to June 1990, 13 institutions in our country studied jointly the application of a 20-item neonatal behavioral neurological assessment (NBNA) in asphyxiated babies. Of 145 cases, 125 were followed up to 1-2 years of age. The results showed that in predicting prognosis, the sensitivity and specificity of NBNA score at 7 days after birth were 88.9% and 82.6% and 12-14 days, 84.6% and 97.4% respectively. Its value in predicting prognosis is superior to Sarnat degree, cranial CT and B ultrasound. This method is practical, economical and reliable. It is worth popularizing.

AIM: To study the palliative treatment of malignant obstruction of digestive tract with placement of intraluminal stent combined with intra-arterial infusion of chemotherapeutic drugs. METHODS: A total of 281 cases of digestive tract malignant obstruction were given per oral (esophagus, stomach, duodenum and jejunum), per anal (colon and rectum) and percutaneous transhepatic (biliary) installation of metallic stent. Among them, 203 cases received drug infusion by cannulation of tumor supplying artery with Seldinger's technique. RESULTS: Altogether 350 stents were installed in 281 cases, obstructive symptoms were relieved or ameliorated after installation. Occurrence of restenotic obstruction was 8-43 weeks among those with intra-arterial drug infusion, which was later than 4-26 weeks in the group with only stent installation. The average survival time of the former group was 43 (3-105) weeks, which was significantly longer than 13 (3-24) weeks of the latter group. CONCLUSION: Intraluminal placement of stent combined with intra-arterial infusion chemotherapy is one of the effective palliative therapies for malignant obstruction of the digestive tract with symptomatic as well as etiological treatment.

Background Seventeen million births occur in China each year. Neonatal mortality is the leading cause of under 5-year-old child deaths, and intrapartum-related injury accounts for much of mental retardation in young children. The Chinese Ministry of Health sought to improve infant and child survival through a nationwide initiative to have at least one person trained in neonatal resuscitation at every birth. The aim of the current study was to evaluate the impact of China Neonatal Resuscitation Program （NRP） on policy and infrastructure changes and its effectiveness in decreasing the incidence of mortality among newborn infants. Methods The Chinese NRP incorporated policy change, professional education, and creation of a sustainable health system infrastructure for resuscitation. Multidisciplinary teams from all 31 provinces and municipal states disseminated NRP in a train-the-trainer cascade. The intervention targeted 20 provinces with high neonatal mortality and programs to reduce maternal mortality. Program evaluation data came from 322 representative hospitals in those provinces. Results Changes in policy permitted midwives to initiate resuscitation and required resuscitation training for licensure. From 2004 through 2009 more than 110 659 professionals received NRP training in the 20 target provinces, with 94% of delivery facilities and 99% of counties reached. Intrapartum-related deaths in the delivery room decreased from 7.5 to 3.4 per 10 000 from 2003 to 2008, and the incidence of Apgar 〈7 at 1 minute decreased from 6.3% to 2.9%. Conclusions The Chinese NRP achieved policy changes promoting resuscitation, trained large numbers of professionals, and contributed to reduction in delivery room mortality. Improved adherence to the resuscitation algorithm, extension of training to the township level, and coverage of births now occurring outside health facilities can further increase the number of lives saved.
