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 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 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 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 build information repository of the carrying rate of neonatal deafness gene in Shijiazhuang. METHOD: Blood samples were collected from the heel in 3-days neonates. Mutations of the deafness related genes were detected by the method of fluorescent PCR. Neonates received the detection of 6 mutation sites from 3 genes, including GJB2 (235delC, 299-300delAT), SLC26A4 (IVS7-2A> G, 2168A> G), mitochondrial DNA12S rRNA(1494C>T,1555A>G). RESULT: There were 384 neonates who carried mutations among 421 subjects and the carrying rate was 4.08%, 158 (1.68%) newborns carried heterozygous mutations and 1 (0.01%) case carried homogeneous mutation of GJB2 (235 delC), 55 (0.58%) neonates carried heterozygous mutations of GJB2 (299-300delAT); 133 (1.41%) neonates carried heterozygous mutations and 1 (0.01%) homogeneous of SLC26A4(IVS7-2A>G),19 (0.20%) newborns carried heterozygous mutations of SLC26A4 (2168A>G). The numbers of neonates who carried homogeneous and heterogeneous mutation of mitochondrial 12S rRNA gene were 14 and 3 with carring rates of 0.15% and 0.03%. Two newborns were found to carry more than one mutation. One carried 235delC, IVS7-2A>G and 1555A>G and another carried 235delC and IVS7-2A>G. CONCLUSION The main mutational patterns were 235delC from GJB2 gene and IVS7-2A>G from SLC26A4 gene in Shijiazhuang newborns. The carrying rate information repository of neonatal deafness gene has been built preliminarily.

ObjectiveTo investigate the clinical significance and histological origin of glomerular epithelial proliferative lesion in patients with focal segmental glomerulosclerosis (FSGS). MethodsSeventy-four patients with idiopathic FSGS hospitalized in Peking University First Hospital from Jan. 2000 to Dec.2005 were enrolled in this study. Patients were classified into two groups according to with or without glomerular epithelial proliferative lesion. Estimation of active and chronic pathological scores was carried out using a semi-quantitative grade system by two pathologists. Clinical and pathological characteristics were compared between two groups. Immunohistochemical studies were performed to analyze the histological origin of glomerular epithelial proliferative lesion. ResultsThirty-one patients with glomerular epithelial proliferative lesion showed shorter interval from presentation to biopsy (P<0.05), higher percentage of nephrotic syndrome (NS) (P<0.05), higher frequency of segmental glomerulosclerosis(P<0.05), higher pathological active scores (P<0.05) and lower pathological chronic scores (P<0.05)as compared to 43 patients without glomerular epithelial proliferative lesion. Twenty-nine patients were followed up and renal survival rate in patients with glomerular epithelial proliferative lesion (39.7%) was significantly lower than that in patients without glomerular epithelial proliferative lesion (83.3%) (P=0.049). The frequency of glomerular epithelial proliferative lesion and the serum creatinine (Scr) level at biopsy were independent predictors of ESRD (OR value was 1.204, 1.008 respectively ). Glomerular epithelial proliferative lesion did not express mature podocyte markers including WT-1 and pedocalyxin, but stained positive for PCNA, PAX-2 and CK-8. ConclusionsGlomerular epithelial proliferative lesion represents the pathological change of acute stage and active lesion of FSGS, and also may be the pathological marker of severe clinical presentation and worse renal survival. Glomerular epithelial proliferative lesion may be derived from proliferation of parietal epithelial proliferation or de-differentiated podocytes.

Objective To investigate the influence of early rehabilitation and defibrase on the hemodynamic cerebral vascular dynamic index (CVDI) of hemiplegic patients with acute cerebral infarction. Methods Ninety hemiplegic patients with acute infarction were randomly divided into a rehabilitation and a control group. Both groups received defibrase routine treatment. The rehabilitation group received systematic rehabilitation training in addition. The Fugl-Meyer assessment ( FMA) , the Scandinavian Scoring Scale ( SSS) and Barthel's index ( MBI) were employed to evaluate the functioning of the two groups. The CVDIs of all patients were quantified before and after treatment. Results The FMA, MBI and SSS scores as well as the CVDIs of both groups had improved after 4 weeks of treatment, but all were more improved in the rehabilitation group than in the control group. Conclusions Early rehabilitation was effective for relieving neurological impairment and improving ability in the activities of daily living for patients with acute cerebral infarction.
