Objective To explore the effect of thymosin and MVP chemotherapy on the life quality of non-small cell lung cancer(NSCLC) patients. Methods 50 cases of NSCLC patients who received MVP(MMC, VDS, DDP) chemotherapy,were randomly divided into experimental group (using thymosin α1) and control group;before chemotherapy and at the end of chemotherapy (the first 2 weeks), the quality of life was evaluated and analyzed comparatively by the FACT-L questionnaire of patients with lung cancer-Chinese version (V4.0). Results The re-sults of the experimental group score increased by (3.13±2.29),and control group score increased by(-1.07± 2.19) with significant differences (P<0.01). Conclusions Thymosin α1 can improve the short-term quality of life of the non-small cell lung cancer patients who received MVP chemotherapy.

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 (P0. 05). APACHE II scores after treatment were significantly lower than that before treatment in the two groups (P<0. 05). and no significant difference was found in the LVEF or the length of ICU slay after treatment between the iwo groups (P>0. 05). The therapy group had a significantly lower 28-day mortality than the control group (0. 05). The therapy group had a significantly lower mortality than the control group (P<0. 05). Conclusion Therapeutic effect of Shuxuening on the severe sepsis patients with myocardial injury is superior to the routine treatment. Shuxuening can decrease the levels of NT-proBNP. hFABP. cTnl, and MDA and APACHE || score, and can increase the activities of SOD and GSH-Px.

Objective To discuss the feasibility and accuracy of left atrial appendage (LAA)ejection fraction by real-time 3 dimensional imaging (3D-EF),and tissue velocity of the LAA wall by tissue Doppler imaging (TDI)via transesophageal echocardiography (TEE)in assessing LAA functions.Methods A total number of 76 patients with atrial fibrillation (AF)were included in the study consecutively and underwent TEE for LAA investigations.3D-EF,fractional area change by 2 dimensional imaging (2D-FAC),peak emptying velocity (PEV),LAA tissue velocity by TDI at the mid-portion of lateral wall (TDI-L),mid-portion of septal wall (TDI-S)and the apical tip (TDI-A)were calculated.Results Statistic analysis showed the following results:1 )2D-FAC,3D-EF,PEV,TDI-L,TDI-S and TDI-A were all significantly higher in patients with sinus rhythm than those with AF during the TEE examinations (all P <0.05),and significantly higher in patients without spontaneous echo contrast (SEC)than those who had SEC (all P <0.05);2)The results of 3D-EF showed a good correlation with 2D-FAC (r=0.727,P =0.000),and their correlations with PEV were similar (2D-FAC and PEV:r =0.685;3D-EF and PEV:r =0.632,both P =0.000);3)TDI-A [(14.95±4.63)cm/s]were significantly higher than TDI-L [(12.62±3.96)cm/s]and TDI-S [(12.68±3.59)cm/s](both P =0.000).The correlations of TDI-A with PEV,2D-FAC and 3D-EF were all marked higher than those of TDI-L and TDI-S (with PEV:r=0.840 vs r=0.564,r=0.524;with 2D-FAC:r=0.701 vs r=0.486,r=0.504;with 3D-EF:r=0.753 vs r=0.493,r=0.522,all P <0.05). Conclusions 3D TEE is feasible and reliable in assessing LAA emptying function.The best location for LAA tissue velocity evaluation is the apical tip.

Objective To explore acute toxicity of succimer on mice.Methods Twenty Kunming mice(10 males and 10 females) weighting approximately (21.2?2.3)g were acclimatized for 3 days prior to dosing,then were divided into control group and experiment group with 10 mice in each group according to body weight.Fasted for 12 hours,the mice in experiment group received intragastric administration of 160mg DMSA in deionized water in 24 hours,and the control group received the same volume of deionized water,and then they were observed for 7 days.Blood was collected into heparinized-tubes by removal of eyeball.All mice were sacrificed and brain,heart,liver and kidney were removed and washed with normal saline.The activity or amount of BUN,Scr,AST,ALT,SOD, GSH-PX and MDA were analyzed.Results (1)Given 160rag DMSA in 24 hours,gastrointestinal symptoms were main side effects.During the observation,experiment group lost weight due to the decrease of food-intake ,and some mice had slight hydroabdomen.(2)High dose of DMSA caused a significant inhibition of GSH-PX(P0.05).The hepatic cell was damaged accord- ing to the significant raise of MDA in liver(P0.05),which was related to acute toxicity on liver.Conclusion Succimer could inhibit the antioxidarrt systems and could do damage to liver and kidney.

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 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.
