Objective To explore the effects of prenatal infection on the development of lungs by dynamic observation of morphology and numbers of inflammatory cells in lungs of rat pups exposed to antenatal inflammation.Methods Pregnant Wistar rats were randomly divided into experimental group and control group.Pregnant rats of both groups were intraperitoneal injected with either lipopolysaccharide (LPS) 2.5mg/kg or the same volume of normal saline on embryonic day 19 and 20, respectively, and were allowed to term deliver.Onday1, 3, 7, 14, 21and28 (D1, D3, D7, D14, D21 andD28), eight pups of each group were killed by 10％ chloral hydrate (1ml/kg) and lungs were collected.The numbers of myeloperoxidase (MPO) and CD68 as markers of both neutrophils and macrophages were counted.Morphometric assessments were performed by measuring the mean numbers of alveolar, the mean ratio of alveolar surface area to per tissue and the mean thickness of alveolar septum.Results With the increasing of postnatal days, the mean numbers of alveolar and the mean ratio of alveolar surface area to per tissue in both groups increased.The mean thickness of alveolar septum got thinner and the numbers of inflammatory cells decreased.On D1, D3, D7 and D14, the mean alveolar numbers of the experimental group (88, 89, 102 and 127 /mm2) were significantly less than those of the control group (105, 109, 123, 156/mm2), P =0.024, 0.009, 0.013, 0.004, respectively.On D1, D3 and D7, the mean ratios of alveolar surface area to per tissue were significantly larger (0.552,0.603 and0.533) than those of control group (0.478, 0.485 and 0.404), P=0.003, 0.001, 0.000, respectively.On D1 and D3, the alveolar septum thickness was significantly thinner (12.30 and 10.75 μm) thanthatin control group (17.13 and 16.13 μm), P=0.000, 0.000, respectively.On D1, D3, D7 and D14, the mean numbers of neutrophils of the experimental group (681, 582, 393 and 379/mm2) were significantly more than those of control group (164, 211, 145 and 179 /mm2), P =0.000, 0.000, 0.000,0.003, respectively.On D1, D3 and D7, the mean numbers of macrophages (613, 578 and 337 /mm2)were significantly more than those of control group (170, 182 and 127, /mm2) , P=0.000, 0.000, 0.000,respectively.Conclusion Prenatal infection results in larger and fewer alveolars and more inflammatory cells in lungs of rat pups.With the increasing of postnatal days, the alveolar morphology was similar to the controis.

Objective To compare the effects of total intravenous anesthesia or Intravenous-in-halation combined anesthesia on intraoperative somatosensory evoked potential (SSEP)and motor evoked potential (MEP)in spinal surgery.Methods Sixty patients scheduled for spinal surgery under general anesthesia were divided randomly and equally into 2 groups.The anesthesia was maintained with TCI propofol (plasma target concentration 3.0-3.5 μg/ml)and 1% sevoflurane+propofol in group T or group I respectively.BIS was monitored and maintained at 40-50.SSEP and MEP was re-corded before induction of anaesthesia (T0 ),5 minutes after tracheal intubation (T1 ),during skin in-cision (T2 )and at the time of decompressing spinal canal (T3 ).Results The latency of P38 and N45 prolonged,and the amplitudes of P38 and N45 was significantly depressed at T1-T3 compared to those at T0 (P <0.05).No statistically significant differences in cortical SSEP amplitudes or latency was observed in each time point.There was no case who could not detect the wave of MEP intraoperative-ly in this study.Conclusion The data from these cases indicates that 1% sevoflurane can be used in conjunction with SSEP and MEP monitoring for some adult patients undergoing spinal surgery.

Background Congenital cataract is the major cause of blindness in children with plentiful clinical manifestations and closely linked with genetics. Objective Present study was to investigate the classification of congenital cataract in Yunnan province.Methods The manifestation characteristics of 184 eyes of 116 patients with congenital cataract in Yunnan province were analyzed.The relationship of performance of various types of congenital cataract between phenotype and hereditary feature were explored. Results All of the 116 congenital cataract eyes from 116 patients were divided into ten types based on the clinical appearance,including the complete cataract,nuclear cataract,posterior polar cataract,anterior polar cataract,coralliform cataract,coronary cataract,pulverulent cataracts,lamellar cataract and blue cataract.Bilateral nuclear cataract and unilateral entire cataract is most prevalent in these patients.Blue cataract and coralliform cataract belong to the less types.Forty-four in 116 cases were found to have the hereditary history and determined as autosomal dominant inheritance.Sporadic cases were determined in 72 cases.Conclusions The analysis of phenotype of the hereditary congenital cataract offers some clues to the classification of congenital cataract.

Objective To explore the promotion model with the sustainable development of appropriate technologies in rural health. Methods After a large-scale government-led, administrative intervention mode (Ⅰ mode) , the mode (Ⅱ mode) dominated by the third sector and participated in by the whole society was used in some counties, and Ⅲ model, an enterprise-led and market economy controlled mode was adopted in Tongliang County. Results The primary care doctor and patient satisfaction in the third sector participation mode, and the personal experiences of doctors in enterprise-led mode were evaluated as excellence. The differences of experience of both doctors and patients between the third sector-led and government-led were statistically significant (P<0.01) ; he third sector-led mode was better than government-led mode. Conclusion It needs to establish a long-term pattern with the government supervision and policy support, the third sector and business management, full community participation, and regulation of market economy rules for the sustainable promotion model of appropriate technologies in rural health.

Objective To understand the personality and self-rated health status and the relationship between them in medical students. Methods By multi-stage cluster random sampling, 878 medical students were selected to investigate the personality by Eysenck Personality Questionnaire-Revised (Short Scale For Chinese) and the health status by self-rated health measurement scale (SRHMS1.0). Results The score of L dimension among male and female medical students was significantly higher than that of nation- wide young population. The scores of E, N and P dimensions had no significant difference between them. The score of P dimension of male students was significantly higher than that of female students. The score of students' SRHMS was 339.28?41.19, which was higher than that of general population in China. The score of physical health subscale among male and female students was 144.90?11.41 and 142.73?11.36, respectively (t=2.829, P=0.005). The scores of SRHMS and its three subscales were significantly different in medical students with different personality traits except the score of physical health subscale in students with different grades of P dimension. The scores of E and L dimensions had significantly positive correlation with SRHMS, and the scores of N and P dimensions had significantly negative correlation with SRHMS. Conclusion The personality traits of medical students were remarkably influenced on their self-rated health. To encourage medical students to reform the wholesome personality will be helpful to their health.

Objective To explore the influence of personality and negative life events on the development of pulmonary tuberculosis among diabetic patients.Methods A hospital-based case-control study was conducted from March 2005 to February 2006.158 newly-diagnosed pulmonary tuberculosis patients with diabetes (DMPTB) were reemited as cases and 281 diabetic patients (DM) as control group.Information on personality and negative life events was collected using Eysenck Personality Questionnaire (EPQ) and Life Events Scale (LES),respectively.Odds ratios(OR) and 95% confidence intervals (95% CI) were estimated using logistic regression models and the potential confounding bias was controlled through adjusted by education,income,glycemic control,previous maximal BMI,weight loss ratio,physical xercises,smoking,negative life events or personality.Results The proportions of introversion,medium,extroversion personality in DM-PTB and DM group were 38.6% ,11.4% ,50.0% vs.53.0% ,11.1% ,35.9% (X~2=9.280,P=0.010).Those with introversion personality had 1.91 (1.26～2.90) times higher risk of DM-PTB than those with extroversion personality,while this association became insignificant after adjustment(P=0.111) ; 35.4% and 19.6% in the two groups had experienced life events during the last one year,and such persons had 2.26(1.15～3.50) (unadjusted) or 1.82(1.07～3.10)(adjusted) higher risk of DM-PTB than those without life events,especially among male and younger (＜60y) diabetics.Conclusion Negative life events are the independent risk factor of pulmonary tuberculosis among male and younger diabetics.Thus,mental measures should be taken in corresponding risk populations to improve their capability of dealing with life events.
