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 understand change and pathogenesis of microalbuminuria(MAU) in cases of adiposity.Method MAU were measured by immunoturbidmetric methods 300 cases of adiposity and 100 cases of nomal children in morning,meanwhile blood press,blood su-gar,blood fat,blood insulin were measured.Results MAU was higher in cases of middle and severe adiposity than normal controls.The diffe-rence was significant(Pa

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.

Microglia is the most important immune cell in the central nervous system.It plays a key role in mediating the immune response in the central nervous system.Sterile inflammation is the key factor in the pathophysiological process following ischemic stroke.Microglia is activated and induces a series of inflammatory signals through binding of injuring related ligands to their corresponding receptors.This article introduces the activation of microglia and inflammatory response after ischemic stroke from Toll-like receptors,inflammasome,cytokine receptors,Notch signaling and other signaling pathways.

OBJECTIVE:To explore the effects of alendronate sodium on bone mineral density (BMD) and bone marker in prostate cancer elderly patients after medical castration therapy. METHODS:In perspective study,84 elderly patients undergoing medical castration therapy were selected and divided into treatment group(45 cases)and control group(39 cases)according to ran-dom number table. Control group received medical castration therapy+Calcium carbonate D3 tablets,1 tablet,po,qn;treatment group was additionally given Alendronate sodium tablets 70 mg,po,once a week,1 week after routine treatment,on the basis of control group. Treatment course of 2 groups lasted for 12 months. The levels of 25-OH-D,testosterone,BMD and bone marker were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:3 cases of treatment group and 1 case of control group dropped out of the study. Before treatment,there was no statistical significance in above indexes between 2 groups (P>0.05). After treatment,25-OH-D levels of 2 groups were increased slightly,but there was no statistical significance(P>0.05);tes-tosterone level of 2 groups were decreased significantly compared to before treatment,with statistical significance (P<0.05). 12 months after treatment,BMD of lumbar vertebra,collum femoris and hip were increased significantly in treatment group,while those were decreased significantly in control group;there was statistical significance in above indexes between 2 groups(P<0.05). The levels of N-terminal midfragment of osteocalcin,procollagen Ⅰ N-terminal propeptide and β-crosslaps were decreased signifi-cantly in treatment group,while those were increased significantly in control group;there was statistical significance in above in-dexes between 2 groups (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Alendronate sodium can prevent bone loss and reduce the rate of bone turnover in elderly patients with prostate cancer receiving medical castration therapy.
