AIM:To evaluate the efficacy and safety of the regimen based on platinum compound plus docetaxel in the treatment of advanced esophageal carcinoma as first-line drug,and to further explore prognostic factors of advanced esophageal carcinoma by survival analysis.METHODS:From August 2006 to October 2008,36 patients with advanced esophageal carcinoma were enrolled in the study,and non-randomly assigned to docetaxel 75 mg/m2 in the first day every 3 weeks,combined with cisplatin 25 mg/m2 in the first day to third day or in the first day to forth day(DT,n=27),or with carboplatin AUC=5 on day 1(CT,n=9).RESULTS:The curative and toxic side effects were evaluated to the 36 patients.There were 1 complete respone,17 partial respone,11 no changes and 7 progressive disease in 36 patients with total response rate of 50.00%.The response rates of DT,CT regimen were 59.26% and 22.22%(P=0.121).The major side effects were nausea-vomiting,all side effects were reversible by symptomatic treatment.After a median follow-up of 8.70 months,the overall median survival was 10.50 months(95% CI 7.36 to 13.64 months).The COX univariate regression analysis suggested there was no correlation with sex,age and the hemoglobin of before chemotherapy with existence.But there was statistical significance between the behavior state of chemotherapy and the existence(P=0.036).CONCLUSION:The regimen based on platinum compound plus docetaxel is tolerable and more effective as a first-line treatment for advanced esophageal carcinoma.Patients with good performance status before chemotherapy indicates good prognosis and it is an independent factor affecting survival for advanced esophageal carcinoma.

Objective To investigate the effects of extracorporeal membrane oxygenation (ECMO) on survival of adult from acute respiratory distress syndrome (ARDS). Method We searched Pubmed, Embase, Cochrane Library, Web of Science databases to find relevant literatues on ECMO in treatment of ARDS, which are reported from January 1966 to June 2010. Meta analyses was performed. Results Three papers about randomized controlled trial (RCT) of evaluating ECMO in patients with severe ARDS were enrolled for analyses. Meta-analysis of the three randomized controlled trials revealed ECMO did not decrease the mortality of ARDS patients. However, the cumulative meta-analysis of randomized trials showed ECMO had a protective effect on patients with ARDS. The most recent observational studies suggested that ECMO significantly decreased the mortality of ARDS caused by H1 N1 viral pneumonia. Conclusions There is no evidence to prove the benefit of ECMO in patients with ARDS. However, ECMO should be considered to use in early stage of ARDS as a last rescue resort for potentially reversible severe acute respiratory failure. Further investigation of large sample of high quality RCTs is needed.

Objective To investigate the effects of elasticity resistance (Ers) in respiratory system on oxygenation in patients with acute lung injury (ALI) after recruitment maneuvers (RM). Method Meta-analysis of data about the effects of recruitment maneuvers on oxygenation in ALI patients with different elasticity resistances in respiratory system carried out with pooling of study-oriented data stored in Pubmed, Embase, Web of Science databases from January 1999 to June 2010. Results A total of 281 articles were taken, and 20 of them included a sample size of 395 ALI patients. In patients treated with RM in different degrees of respiratory system elasticity resistance ( ≥33.3 cmH2O/L and ＜33.3 cmH2O/L), the effect of RM was better in patients with the high respiratory system elasticity resistance than that with the low one [(51.97 + 8.89) mmHg vs. (35.13 ± 10.33 ) mmHg], P ＜ 0. 01 ), but the high respiratory system elasticity resistance was potentially to lower blood pressure [(4. 33 ± 1.32 ) mmHg vs. (0.22 ± 1.03 ) mmHg],P ＜ 0.01 ). Conclusions This study suggests RM could improve oxygenation of ALI patients with high respiratory system elasticity resistance, and caution must be made to avoid hypotension during RM.

OBJECTIVE: To analyze the utilization of traditional Chinese medicine (TCM) injections in our hospital in order to provide reference for clinical rational use of TCM injection. METHODS: The utilization of TCM injection in our hospital from 2006 to 2008 was statistically analyzed in terms of consumption sum, DDDs and its order. RESULTS: The consumption sum and DDDs of TCM injection in our hospital increased year by year, especially stasis-removing agents and antitumor drug. Over the 3 years the proportion of consumption sum of TCM injections in the total consumption sum were 57.3%, 59.4% and 55.9%, respectively. There was poor synchrony between consumption sum order and DDDs order. CONCLUSION: TCM injections are used rationally in our hospital. In addition, safety reevaluation of TCM injection should be improved.

The growth and development of plant is affected by environmental factors that include light,temperature and water. Many cis-elements that are response to these elicitors interact with transcription factors, and regulate the expression of target genes. It concludes by pointing out recent studies of cis-elements and transcription factors in the plant environmental response promoters, such as light, temperature and water inducible promoter. The molecular mechanisms of gene expression regulated by environmental factors was discussed. This is important to study the mechanisms that plant adapt the environment.

AIM: To study the effect of berberine on the proliferation of human pulmonary carcinoma cells (PG cells). METHODS: The proliferation of PG cells was determined by using MTT assay. Cell cycle and apoptosis of PG cells were determined by using flow cytometry. Confocal scanning imaging system was used to assay the ROS-releasing level of PG cells. RESULTS: Berberine was shown to inhibit proliferation of PG cells directly and in a concentration-dependent manner (P

Objective To study the relationship between Noble grade and distribution of myocardial bridge and atherosclerosis. Methods The clinical data of 192 patients with myocardial bridge diagnosed by coronary artery angiography were retrospectively analysed.The clinical symptoms,electrocardiographic and echocardiographic findings were analysed to explore the relationship between Noble grade and distribution of myocardial bridge and atherosclerosis,and the outcomes of medical treatment were also investigated. Results The positive rate of myocardial bridge detected by coronary artery angiography was 10.2%,which was usually observed in the middle part of left anterior descending coronary artery.All the patients with grade 3 of Noble grade experienced chest pain or palpitation,43.8% had ischemic ST-T changes on electrocardiogram,and 37.5% had abnormal segmental ventricular wall on echocardiography.However,patients with Noble grade 1 and 2 did not have ischemic ST-T changes on electrocardiogram or abnormal segmental ventricular wall on echocardiography.The prevalence of atherosclerosis in proximal coronary artery of myocardial bridge was significantly higher than those of mural coronary artery and distal coronary artery(P
