Objective To explore the effect of Shuxuening on early myocardial injury markers and oxidative stress in severe sepsis patients with myocardial injury. Methods A total of 102 severe sepsis patients with myocardial injury, who received therapy in our hospital from Mar. 2013 to Jun. 2016, were randomly divided into two groups; control group (51 cases) and therapy group (51 cases). The patients in the control group received routine treatments and the therapy group were given Shuxuening based on routine treatment. We detected the levels of plasma N-terminal pio-brain natriuretic peptide (NT-proBNP), heart-type fatty acid binding protein (hFABP), cardiac troponin I (cTnl), malondialdehyde (MDA), superoxicle dismutase (SOD) and gluiaihione peroxidase (GSH-Px) of patients before treatment (at admission), after treatment for 6 h and 72 h (after admission), and analyzed the change of left ventricular ejection fraction (LVEF), acute physiology, chronic health evaluation (APACHE) || score, length of ICU slay and 28-day mortality of the patients. Results At admission, there was no difference in the levels of plasma NT-proBNP, hFABP, cTnl. MDA. SOD. GSH-Px, APACHE || score or LVEF between the two groups (P>0.05). After treatment for 6 h, the levels of plasma NT-proBNP, hFABP, cTnl and MDA in the therapy group were significantly lower and the activities of plasma SOD and GSH-Px were significantly higher than those in the control group (P

OBJECTIVETo study the epidemiology of human metapneumovirus (hMPV) infection in children and its relations with meteorological conditions in Suzhou.
METHODSamples obtained from 6655 children hospitalized with acute respiratory tract infections (ARIs) during the period from 2006 to 2009, were tested for virus pathogens. Nasopharyngeal aspirates were obtained from the children according to a standard protocol and were tested for respiratory syncytial virus (RSV), influenza viruses (IFV) A and B, parainfluenza virus (PIV) types 1, 2, and 3 and adenovirus (ADV) with direct immunofluorescence assay. Samples were tested for hMPV with reverse transcription polymerase chain reaction (RT-PCR). Meteorological conditions including mean temperature, relative humidity, rainfall amount, sum of sunshine and mean wind velocity were collected monthly. The relationship between activity of the virus and meteorological conditions was analyzed by linear regression and stepwise regression analysis.
RESULTViral pathogens were identified in 32.2% of 6655 specimens. The positive rate of hMPV was 8.9%, RSV was 15.7%, IFV, PIV and ADV detection rates were less than that of hMPV. The annual positive rate of hMPV from 2006 to 2009 was 8.2%, 8.1%, 12.7%, 7.4% respectively (χ(2) = 33.23, P < 0.05). The hMPV positive rate of the four seasons was 11.6%, 7.6%, 4.7% and 11.7%, respectively, detection rate in winter and spring was significantly higher than those in summer and autumn (χ(2) = 74.67, P < 0.001). The positive rate of hMPV and the monthly mean temperature was moderately correlated (r = -0.43), and the monthly average rainfall (r = -0.29), monthly mean relative humidity (r = -0.27), monthly average sunshine duration (r = -0.11), the monthly average wind speed (r = -0.13) had low correlations.
CONCLUSIONhMPV was the second most common viral pathogen of acute respiratory tract infection in children in Suzhou, which prevailed predominantly in the winter and spring. Climatic factors, especially temperature and rainfall may affect the prevalence of hMPV.

OBJECTIVETo explore the lung cancer incidence rates from 1972 to 2001 and utilize varieties of models in forecasting trend up to 2010 in the city of Qidong, Jiangsu in order to provide baseline data for its control and prevention.
METHODSUsing data from the cancer registry office in Qidong, we tried to reveal the trends of lung cancer incidence by analyzing the time-series on trends extrapolation, exponent smoothness, Box-Jenkins model etc. We also compared the prognostication precision, endow differ power, and established assembled forecast model.
RESULTSData showed that there had been a rising trend of lung cancer from 1972 to 2001 and would still probably be on the increase in the future. The rate of male and female attained to 70 per 100 000 and 20 per 100 000, predicting that there would be a respective 33 percent and 10 percent increase in 2010.
CONCLUSIONSAccording to analysis of forecast models, it was right to prognosticate lung cancer incidence from time-series and improve forecast precision through developing combination models. The result of combination seemed close to ARIMA models which suggested that it could serve as a chief way to forecast the incidence of lung cancer.

OBJECTIVETo evaluate the surgical therapeutic strategy and prognostic factors for non-small cell lung cancer (NSCLC) with mediastinal lymph node metastasis (N2).
METHODSThe survival rate of 117 patients with N2 NSCLC treated surgically from January 1999 to May 2003 were analyzed. There were 88 male cases and 29 female cases, aged from 29 to 79 years. The procedure of operation (lobectomy, pneumonectomy and palliative resection), histological classification (squamous cell carcinoma, adenocarcinoma, mixed carcinoma, and large cell carcinoma and others), T primary tumor status, and adjuvant therapy were analyzed to determine their impact on the 5-year survival rate.
RESULTSThe median survival time was 22 months, and the over-all 3- and 5-year survival rate was 28.1% and 19.0%. Survival was higher in patients with lobectomy than with palliative resection, with T1 and T2 than with T4. The 5-year survival rate had no deference in age, sex and different histological classification. The 5-year survival rates of lobectomy and pneumonectomy (22.2% and 25.0% respectively) was higher than palliative resection (9.1%).
CONCLUSIONSSurgical procedures (especially lobectomy) is the best choice for N2 NSCLC patients with T1 or T2. But it can not prolong T4 patients' life significantly.
