RESULTS①As compared with the values in the control group,the latency of waveⅤfor both ears,waveⅠ-Ⅴand waveⅢ-Ⅴintervals for the right were significantly prolonged(P

Objective To analyse both micro level and macro level factors influencing maternal mortality in order to set the priority to lowering maternal mortality. Method The results of an analysis of maternal mortality were reported, based on a conceptual model that combines micro level and macro level variables taken from demographic, sociological and epidemiological research. Multi level analysis techniques were used to analyse the 1997 linked county level maternal death data and related county level social demographic and health resources data in 114 counties of 5 remote and poverty stricken provinces. Results The maternal mortality rate in research areas was as high as 159.3/100 000. The main factors influencing maternal mortality were institutional delivery rate, population density, percentage of minority population, and percentage of village without village doctor. Conclusion To advocate institutional delivery rate, to pay greater attention to minority and low population density area, and to standardised village doctors' responsibility are recommended strategies to lowering maternal mortality in remote and poverty stricken areas of China.

Objective To analyze the descending trend of maternal mortality ratio (MMR) and its related influencing factors in order to improve the descending speed of MMR. Methods The influencial factor analysis and u test were made on data collected from 232 rural counties of eight provinces in China. Results MMR had shown remarkable reduction from 1995 to 2000, a drop by 51.33%. However, there was still a gap if compared with the ratio of the whole country. Major causes influencing the descending speed of MMR include the high speed of economic development, more expenditure of health, quality of maternal service, such as the ratio of hospital delivery, cleaning delivery, prenatal and postnatal health care. Conclusion In order to accelerate the descending speed of MMR, attempts to increase the improvement speed of maternal health care, quality of maternal service and more expenditure of health should be made.

Objective To understand the trends of institutional delivery in recent 30 years in China and find out the main social and demographic factors. Methods Two-staged PPS method was employed for sampling; Uniform questionnaire was drafted and direct interview was adopted to collect the information. Results The institutional delivery rate was increasing rapidly with time, especially from 1990's, which had climbed to 82% in the last three years, but it was still unsatisfactory in the central and western areas. Meanwhile, most women who delivered outside the hospital were assisted only by birth attendants/village doctors or family members/friends in labor. Factor analysis showed that the women s education and occupation and their husbands, the gap of education between the couples, and the antenatal care could significantly affect their choice for where to deliver. Conclusions Great improvement had been achieved in the last several decades, and both individual characteristics, community and health facility could have influences on the women s decision on where to give birth.

Objective To investigate the status of breastfeeding rate at discharging hospital and analyze influence of obstetrical service quality on breastfeeding rate, in order to improve the quality of obstetrical service and increase the breastfeeding rate. Methods A total number of 1 123 mothers who have 6~12 months babies were investigated through questionnaire including obstetrical service accepted, situation of breastfeeding rate at discharging hospital, mother's breastfeeding knowledge and behaviors with across-sectional method from August to October in 2000. Seven cities were chosen as the research site including Beijing, Changchun, Huhehaote, Xi'an, Luoyang, Kunming and Xiamen. The data were analyzed with SPSS/PC 10.0 statistical software. Results The exclusive breastfeeding rate was 52%, the full breastfeeding rate was 73% at discharging hospital. The influencing factors of breastfeeding rate at discharging hospital include mother's age, medical expenditure type, caesarean section, breastfeeding on demand, neonatal status, having milk bottle, feeding milk-powder and sweeten water in obstetrical wards, mother's breastfeeding knowledge and behavior, et al. Conclusions Breastfeeding rate at discharging hospital was low and it was related with quality of obstetrical service. So it is important to improve the quality of obstetrical service and health education on breastfeeding, in order to enhance the breastfeeding rate.

Objective To explore the inhibitory effects of lobaplatin and cisplatin and their regulation of apoptosis-related genes in ovarian cancer cells in nude mice.Methods SKOV3 cells were implanted into nude mice.In monotherapy treatment study,the nude mice bearing human SKOV3 cells were randomly divided into control,lobaplatin,and cisplatin groups,with 7 mice in each group.The mice in each group were received corresponding treatment.The volume of tumor and the weight of nude mice were measured three times per week,respectively.Tumor inhibitory rate was calculated.The protein expressions of bax and bcl-2 were detected by flow cytometry.Results The growth inhibitory rate was 47.2％ in lobaplatin group and 42.8％ in cisplatin group,without significant difference between two groups (P ＞ 0.05).The expression of bcl-2 was decreased but the bax was increased in lobaplatin and ciaplatin groups compared to the control group.Conclusions Lobaplatin can significantly inhibit the growth of ovarian cancer cells,induce apoptosis by down-regulation of bcl-2 and up-regulation of bax.

Objective To investigate the etiological characteristics of non-bacterial pneumonia in children in Xi'an. Methods Virus IgM antibody was detected by solid phase ELISA technique, and mycoplasma pneumonia(MP) IgM antibody was detected by Au-mark immunodotting technique. Results In a total of 302 cases, mycoplasma pneumonia and / or virus were detected in 204, with the positive infection rate as 67.55%(204/302); 328 cases were found with positive strains of pathogens including 120 mycoplasma(MP) strains (36.6%) among which were 77 coxsackie virus(CV) strains (23.5%), 56 respiratory syncytial virus(RSV) strains (17.1%), 39 influenza virus strains(11.9%), 25 adenovirus strains(7.6%) and 11 EBV strains(3.4%). The single infection rate was 51.99%(157/302) while the mixed infection rate was 15.56%(47/302). The onset of non-bacterial pneumonia in Xi'an could be seen in all seasons of the year. There was significant seasonal difference among the incidences caused by different pathogens(P0.05). The highest incidence age was between 7 months to 3 years. Conclusion MP, CV, RSV are the leading pathogens that cause non-bacterial pneumonia in children in Xi'an. ELISA and Au-mark immunodotting techniques are simple and quick to detect viruses and mycoplasma.
