Objective To observe the inhibitory effect of IL-4 on the IL-1?-induced rat mesangial cell proliferation, the release of PGE 2, and on the COX-2 mRNA and protein expression, so as to explore the related mechanism of anti-glomerulosclerosis. Methods Rat mesangial cell (MC) was cultured in vitro and the IL-1? -induced proliferation of MC was detected by MTT method. ELISA method was employed to measure the contents of PGE 2 in blank control group, IL-1? group, IL-4+IL-1? group, NS-398 group, NS-398+IL-1? group, indomethacin group, indomethacin+IL-1? group. The expression of mRNA and protein of COX-1 and COX-2 gene were detected by RT-PCR and Western blot, respectively. Results IL-1? could induce the proliferation of MC when the concentration was 0.1-100ng/ml in 12h, 24h and 48h. When its concentration was 2ng/ml, it had the strongest effect in 24h. All the IL-4, NS-398, indomethacin could inhibit IL-1? to induce MC producing PGE 2. The inhibitory rates are in proper order as: IL-4 (84.9%), NS-398(56.5%), and indomethacin(41.2%). Both IL-4 and NS-398 could obviously inhibit the expression of COX-2 mRNA and protein proved by RT-PCR and Western blot. Indomethacin could strongly inhibit the expression of COX-1 mRNA and protein, while only shew a weak inhibition on the expression of COX-2 mRNA and protein. Conclusion IL-4 could markedly inhibit the IL-1? -induced MC proliferation, down-regulate COX-2 gene, decrease the production of PGE 2, and thus take effect on anti-glomerulosclerosis.

Objective To explore the DSA mainfestations of MoyaMoya disease.Methods 19 patients, underwent CT before DSA, showed intracranial hemorrhage. All patients were then examined by angiography via femoral artery approach. Results All cases were diagnosed as MoyaMoya disease through DSA. The findings of DSA showed characteristic manifestations as the following: 1. Stenosis or occlusion of the invoved arteries. 2. Smoke like capillary vascular network spreading from supraseller cistern to cerebral base. 3. Development of collateral circulation. Conclusions DSA is the main method for the diagnosis of MoyaMoya disease, CT can only localize the site of cerebral hemorrhage.

Objective: To evaluate the impact of fine particulate matter ( PM2.5 ) on respiratory diseases and symptoms of community residents in Chun’an County, so as to provide the basis for air pollution treatment strategies. Methods: Using the cluster random sampling method, the permanent residents in Qiandaohu Town of Chun’an County were investigated from 2017 to 2018. The demographic information, respiratory diseases and symptoms were collected by using Surveillance Plan for the Impact of Air Pollution ( Haze ) on health ( 2016 Edition ). The air pollutants and meteorological data were collected through Qiandaohu station of Hangzhou Ecology and Environment Monitoring Center and Hangzhou Meteorological Information Center. The effects of PM2.5 on respiratory diseases and symptoms of residents were analyzed with generalized estimating equation. Results: Totally 1 181 people aged 6 months to 95 years were recruited, including 557 ( 47.16% ) males and 624 ( 52.84% ) females. Acute nasopharyngitis (common cold) and tracheitis/tonsillitis occurred most frequently, with 203 cases, accounting for 3.44%. The median of daily average concentration of PM2.5 was 24 μg/m3, with the standard exceeding rate of 2.80%. The results showed that PM2.5 increased the risk of acute nasopharyngitis ( common cold ), tracheitis/tonsillitis, cough, expectoration, runny nose, sore throat and nasal congestion ( lag 3 days, OR: 1.015-1.022, 95%CI: 1.001-1.037 ); the effect of PM2.5+PM10 ( OR: 1.020-1.040, 95%CI: 1.006-1.070 ) and PM2.5+O3 ( OR: 1.017-1.024, 95%CI: 1.005-1.035 ) was greater than that of PM2.5 alone on respiratory diseases and symptoms. Conclusion Atmospheric PM2.5 exposure in Chun’an County increases the risk of respiratory diseases and symptoms among community residents.

AIMTo observe the differences of hemodynamics and nitric oxide synthase(NOS) activity of ventricular cardiac muscle in two septic shock models and explore the possible mechanism.

METHODSTwo rat models of septic shock[lipopolysaccharide(LPS)-induced and cecal ligation and puncture (CLP)-induced septic shock] were used. The hemodynamic parameters and nitric oxide synthase activity of ventricular cardiac muscle were measured.

RESULTSThe hemodynamic parameters in CLP-induced model were increased in the early stage and decreased in the late stage while in LPS-induced model the parameters showed the same change of the CLP late stage. Both LPS model and CLP model (late stage) showed significant increase in NOS activity, but there was no difference between the two models. After treatment of the NOS inhibitor N-nitro-L-arginine methyl ester (L-NAME), the parameters of CLP-late stage and LPS model increased significantly. The NOS activity reached the highest level in the CLP-middle stage. The production of nitrite/nitrate decreased significantly in LPS model and CLP model(late stage) after treatment of L-NAME, but the nitrite/nitrate produced by constitutive NOS in LPS model was higher than CLP model(late stage).

CONCLUSIONThe increase of the NOS activity may be the main reason to lead to the depression of the hemodynamic parameters. Inducible NOS may play the leading role in the LPS model while cNOS and iNOS have the same effect in the CLP model.
