As a treatment of noninvasive,safe,effective,and easy to operate,external counterpulsation has been widely used in the treatment of ischemic heart disease.The treatment mechanism of external counterpulsation may improve collateral circulation and hemodynamics.Therefore,it can provide a new measure for the treatment of cerebrovascular disease.However,the efficacy and safety of external counterpulsation in the treatment of ischemic stroke still need to be confirmed by a large sample clinical trial.

Objective To discuss the clinical value of subglottic secretion drainage on pulmonary infection in severe craniocerebral injuried patients. Methods Eighty severe craniocerebral injuried patients in ICU with the requirement of tracheotomy were randomized into two groups. Forty patients received aspiration of subglottic secretions as the treatment group and the other 40 patients received usual care as control. Samples were taken from pharynx mop, subglottic secretion and lower respiratory tract secretion for bacterial culture at 48 hours, 7th day and 14th day past tracheotomy. Results The incidence of pulmonary infection was 22.5% in treatment group and 45.0% in control. The same rate of predominant flora in subglottic secretion and lower respiratory tract secretion was 63.0% in patients with pulmonary infection. Conclusions Transposition of the pathologic bacteria in the subglottic secretion is one of the important causes of pulmonary infection, subglottic secretion drainage can lower the incidence of pulmonary infection in severe craniocerebral injuried patients.

Objective To investigate the treatment effects and toxicities of extended-field intensity modulated radiation therapy (EF-IMRT) and intra-cavitary brachytherapy combined with chemotherapy for stage Ⅰ b1-Ⅳa cervical cancer with positive para-aortic lymph nodes.Methods A total of 46 stage Ⅰ b1-Ⅳa cervical cancer patients with positive para-aortic lymph nodes treated at Fudan University Shanghai Cancer Center between 2009 and 2011 were reviewed.Neoadjuvant,concomitant and adjuvant chemotherapy with paclitaxel and carboplatin were administrated for one cycle before radiation therapy,two cycles during radiation therapy or three cycles after radiation therapy.All patients received EF-IMRT and intra-cavitary brachytherapy.The positive lymph nodes received an additional boost dose.Results All patients received EF-IMRT to 50.4 Gy (1.8 Gy per fraction).Twenty-six patients was treated with boost dose of 6.0-8.0 Gy in 2.0 Gy per fraction to positive para-aortic lymph nodes.Thirty-seven patients received a positive paraaortic lymph nodes boost or(and) parametrial boost.All patient also received a high-dose-rate intra-cavitary brachytherapy at the point A dose of 20.0-30.0 Gy in 5.0 Gy per fraction.Total chemotherapy cycles were 189,and the average patient received 4.1 courses.Two cases (4％,2/46) experienced grade Ⅲ gastrointestinal toxicities,no patients suffered grade Ⅳ gastrointestinal toxicities.Fifteen cases (33％,15/46) experienced grade Ⅲ hematological toxicities,and 3 (7％,3/46) experienced grade Ⅳ hematological toxicities.Late grade Ⅲ-Ⅳ toxicity was seen in 3 cases (7％,3/46).The 3 year progressionfree survival rate was 46.2％,and the 3 years overall survival rate was 61.2％.Conclusion EF-IMRT and intra-cavitary brachytherapy combined with chemotherapy is safe and effective for stage Ⅰ b1-Ⅳa cervical cancer with positive para-aortic lymph nodes.

Background and purpose:More than 70 percent of ovarian cancer patients were diagnosed in the advanced stage. Currently the 5-year disease free survival (DFS) of stageⅢC-Ⅳovarian cancer patients wsa about 10 percent after first line chemotherapy. This study aimed to improve the 5-year DFS by three-step chemotherapy according to the mechanisms of ovarian cancer biological characteristics, cytodynamics and pharmacology. Methods:In arm A, the patients received three-step chemotherapy after primary debulking surgery, step one with paclitaxel plus carboplatin (TC regimen), every 3 weeks for 6 to 8 cycles;step two with etoposide plus cyclophosphamide, every 4 weeks for 6 cycles;step three wit carboplatin plus cyclophosphamide every eight weeks for six cycles. In control arm B, we retrospectively analysed 51 cases withⅢC-Ⅳstage ovarian cancer, who had completely response after standard chemotherapy with six to eight cycles of TC after primary surgery during 2007. We compared the 5-year DFS between the two arms. Results:The 5-year DFS of 15 cases in arm A was 80%(12/15), which was signiifcantly higher than that of arm B (5.9%, 3/51, P<0.01). Conclusion: The three-step chemotherapy after optimal debulking surgery in stageⅢC-Ⅳ can improve the 5-year DFS. This regimen is high efficacy, mild side-effect witn low cost, which deserves further exploration.

Plasma level of N-terminal pro brain natriuretic peptide (NT-proBNP) was measured for 362 elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), including 97 of AECOPD complicated with left-heart failure and 265 of isolated AECOPD.Results indicated that there was significant difference in plasma level of NT-proBNP between the two groups ( P = 0.000).With a cut-off value of 1643.5 ng/L NT-proBNP, its sensitivity, specificity and accuracy for identifying AECOPD complicated with left-heart failure in the elderly were 84.4%, 85.3% and 85.1%, respectively.It is suggested that assay for plasma NT-proBNP may be helpful to identify left-heart failure in elderly patients with AECOPD.
