ObjectiveTo analyze the surgical techniques and perioperative patient management of bronchial sleeve resection and plasty, carinal resection and reconstruction, and angioplasty in the treatment of locally advanced central type of lung cancer and summarize the experiences. MethodsWe retrospectively analyzed the clinical data of 21 locally advanced central type of lung cancer patients with bronchial sleeve resection and plasty, carinal resection and reconstruction, and angioplast in our hospital from December 2011 through November 2014. There were 17 males and 3 females with a mean age of 63.2±6.2 years. All operations were successful. The time of operation was 3.29±0.75 h. The hospitalization time was 25.48±22.31 days. No death ocurred during perioperative period. Postoperative complications were found in 3 patients, including 2 patients with atelectasis and 1 patient with bronchopleural fistula. ConclusionBronchial sleeve resection and plasty, carinal resection and reconstruction, and angioplasty apply to treat locally advanced central type of lung cancer not only maximally remove the lung cancer tissue, but also maximally reserve the healthy lung tissue.
Objective To systematically evaluate the effectiveness and safety of omalizumab in treating allergic bronchial asthma. Methods The randomized controlled trials (RCTs) about omalizumab in treating allergic bronchial asthma were searched in databases such as MEDILINE, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data from inception to April 2013. The references of included studies and relevant conference proceedings were also retrieved manually. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then RevMan 5.1 software was used for meta-analysis. Results A total of 13 RCTs involving 4 195 patients were included. The results of meta-analysis showed that: a) Compared with the control group, the trial group revealed lower acute exacerbation of asthma during treatment (RR=0.71, 95%CI 0.65 to 0.77, Plt;0.000 01), and higher rate of patients achieved best/better results in Global Evaluation of Treatment Effectiveness (GETE) (RR=1.61, 95%CI 1.32 to 1.97, Plt;0.000 01). More patients could reduce the inhaled cortisteroid (ICS) by 50% during both treatment (RR=1.40, 95%CI 1.29 to 1.52) and 24-week follow-up period (RR=1.69, 95%CI 1.41 to 2.03). And it also increased the ratio of patients whose Asthma Quality Of Life Questionnaire (AQLQ) score got improved by 0.5 and 1.5 socres. b) There were no significant differences in the incidence of overall adverse events (RR=1.01, 95%CI 0.98 to 1.04) and severe adverse events (RR=0.94, 95CI 0.68 to 1.28). c) There might be the effects of omalzumab in improving lung function and reducing rescue medication use, but they were not obviously observed in the studies. Conclusion In the treatment of asthma, omalizumab can decrease the acute exacerbation of asthma and ICS use, and it is safer to improve the therapeutic effects and quality of life.
Objective To evaluate the therapeutic effect, safty and tolerance of Gankeshuangqing Capsule in the treatment of patients suffering from wind-heat syndrome (acute upper respiratory infection or acute bronchitis). Methods The clinical trials were designed multicentered, double blind, double dummy, randomized and parallel positive drug controlled. A total of 289 patients participated in the trials. Those who suffered from acute upper respiratory infection were given throat virus-detection to make a definite diagnosis of the origins of disease. Results Among the 40 patients who were diagnosed with virus infection, 81.82% in Gankeshuangqing group were healed, but only 50.00% in control group, and significant differences were observed between the two groups (Plt;0.05). At the end of the third day of treatment, the rates of cure and excellence in patients suffering from acute upper respiratory infection were 80.00% in Gankeshuangqing group, and 68.57% in control group, and both groups showed good therapeutic effect，but there was no significant difference between the two groups (Pgt;0.05). At the end of the seventh day of treatment, the rates of cure and excellence in patients suffering from acute bronchitis were 82.35% in Gankeshuangqing group, and 63.77% in control group, and both groups showed good therapeutic effect, and there were significant differences between the two groups (Plt;0.05)；only one patient in Gankeshuangqing group had constipation during the treatment, but there was no evidence showing that it is caused by Gankeshuangqing. Conclusion The results show that Gankeshuangqing Capsule has a definite effect on wind-heat syndrome (acute upper respiratory infection or acute bronchitis) with good safety.
ObjectiveTo explore the changes of the B lymphocyte-derived microparticles (BLMPs) in the bronchoalveolar lavage fluid in patients with chronic obstructive pulmonary disease (COPD),and analyze the correlation between BLMPs changes and the stages of the disease. Methods33 COPD patients in acute exacerbation and 12 COPD patients in stable phase in Southwest Hospital,Xinqiao Hospital,and First Affiliated Hospital of Chongqing Medical University between March 2012 and March 2013 were enrolled in the study. 31 subjects who underwent physical examination and bronchoscopy were recruited as control. The lavage fluid specimens were collected through fiberoptic bronchoscopy,then marked with the corresponding antibodies after centrifugation. The numbers of microparticles were analyzed by flow cytometry. ResultsThe number of the BLMPs was significant different among three groups (P<0.05). Compared with the control group and the stable COPD group,the number of BLMPs in the AECOPD group was significantly reduced (P<0.05). Compared with the control group,the number of the BLMPs in the stable COPD group was reduced but with no significant difference (P>0.05). The numbers of BLMPs had no correlation with the smoking history,gender,age and body surface area. ConclusionThe number of BLMPs is reduced in COPD,especially in the acute exacerbation stage,so the reductions of the BLMPs may be associated with the stages of the disease. Smoking,gender,age,body surface area have no effect on the number of BLMPs.
