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.

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 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.

The Her-2 proto-oncogene encodes a 185kDa transmenbrane glycoprotein p185 which has intrinsic tyrosine kinase activity. It is overexpressed in several malignant human tumors like breast cancer. A chimeric antibody by assembling a single-chain Fv antibody and a human IgG1 Fc fragment was constructed. This chimeric antibody reacts with tumor surface antigen p185c-erbB-2 specifically. In order to put the antibody into clinical application, two steps purification method was used to attain the antibody’s purity more than 95%. Both the lyophilized pharmaceutical formulations of the antibody were found. The formulations can keep the stability and activity of the antibody for at least one year. These results were the foundation of the chimeric antibody for cancer therapy.

Objective To test the reliability and validity of the Chinese version STRATIFY (St Thomas Risk Assessment Tool in Falling Elderly Inpatients) for geriatric inpatients.Methods The scale was translated and 404 geriatric inpatients were evaluated by the Chinese version STRATIFY and evaluate its reliability and validity.Results Chinese version STRATIFY was found with good feasibility.The Pearson correlation coefficient of reliability between testers was 0.951,the retest reliability was 0.885,internal consistency reliability (Cronbach's αt) was 0.523.The values of item-total correlation was over 0.3.The distinguish validity in difference of STRATIFY scores between groups with/without fall history was statistically significant.Predictive validity was moderate,the best cut-off point was determined at 2 points,and sensitivity and specificity were respectively 64.3％ and 78.2％.Conclusions Chinese version STRATIFY applied in Chinese geriatric inpatients showed good reliability between testers,retest reliability,distinguish validity and predictive validity,and it could be used to assess the fall risk of Chinese geriatric inpatients.In addition,as the internal consistency was lower,we can revise the entry of STRATIFY to provide a more accurate predicting tool.
