Kushenhuangqi Injection is made from Chinese herb medicine flavescent sophora and astragalns roots.Seventy-one patients with malignant pleural effusion were randomly divided into two groups: 36 patients were treated with both intrathoracic Kushenhuangqi Injection and chemotherapeutic agent cisplatin (treatment group) and 35 patients were treated with cisplatin alone.The response rate of treatment group was significantly higher than that of control group (31/36 vs 20/35,u=3.020,P<0.01).The rate of adverse reaction (leucopenia,nausea,vomiting etc.) in treatment group was significantly lower that that of control group.The results indicate that Kushenhuangqi Injection can enhance the therapeutic effect of chemotherapeutic agent and reduce its adverse reaction in treatment 0f malignant pleural effusion caused by carcinoma of the lungs.

Objective To analyze the infection status and variation tendency of chlamydia trachomatis (CT) ,Neisseria gonorrhoe-ae(NG) and ureaplasma urealyticum(UU) in female genital tract in northeast Sichuan province during 2005 -2012 to provide the laboratory basis for their diagnosis and treatment Methods The real-time fluorescent quantitative PCR (RT-PCR) was applied to detect the CT DNA ,NG DNA and UU DNA in 1 386 samples from female genital tract and the detection results were performed the statistical analysis .Results The total positive rate of these 3 kinds of pathogens was 62 .8% (871/1 386) .Among the simple in-fection ,UU had the highest positive rate(48 .0% ,665/1 386);the positive rates of CT and NG were only 2 .2% .In the mixed infec-tion ,the positive rate of CT + UU was highest(6 .5% ,90/1 386) ,while which of UU + NG ,CT + NG and CT+ NG+ UU was 2 .5% (35/1 386) ,0 .4% (5/1 386) and 1 .1% (15/1 386) respectively .In different age groups ,the positive rate in the age <20 years old group was 49 .3% ,while which in the age >20 years old groups were all more than 60% .The positive rate of the CT ,NG and UU pathogens in females was in continuous high level during 2005 -2012 ,and which totally showed an increasing tendency . Conclusion CT and UU are the main pathogens in female genital tract infection in this region ,and the positive rate of genital tract infection in females aged more than 20 years is higher ,the infection rate of these 3 kinds of pathogens demonstrates the increasing trend year by year ,so more attention should be paid to the detection of CT and UU in this group for guiding the clinicians to con-duct the diagnosis and treatment .

Objective To explore the differences in antimicrobial resistance of bacteria isolated from different samples ,and to guide antibiotic chemotherapy in clinic .Methods The sputum ,blood ,pus and urine specimens were collected from 2009 to 2013 in our hospital for bacterial identification and drug sensitivity tests by using automatic system .The drug resistance rate of Staphylo‐coccus aureus ,Escherichia coli ,Klebsiella pneumoniae isolated from different samples were compared .Results All isolates of E .co‐li ,Klebsiella pneumoniae were sensitive to imipenem ,ertapenem ,piperacillin/tazobactam and amikacin .All isolates of S .aureus were sensitive to vancomycin ,linezolid ,nitrofurantoin ,quinupristin/dalfopristin .The ESBLs positive rate of E .coli(71 .5% )and the MR‐SA detection rate(79 .9% ) of Staphylococcus aureus from sputum samples were significantly higher than that from other samples (P<0 .05) .The ESBLs positive rate(44 .4% ) of Klebsiella pneumoniae isolates from urine was significantly higher than that from other samples(P<0 .05) .Conclusion The same bacteria isolated from different samples have different antimicrobial resistance rates ,so the selection of antibiotics should based on drug sensitivity tests results for the treatment of the same pathogen infection confirmed by bacterial cultures from different samples .

Objective:To investigate the safety and efficacy of balloon pulmonary angioplasty (BPA) for residual pulmonary hypertension (PH) of chronic thromboembolic pulmonary hypertension(CTEPH) after pulmonary endarterectomy (PEA).Methods:Patients diagnosed as PH after PEA in China-Japan Friendship Hospital from Oct 2016 to Jun 2022 were included. The indication for BPA was decided on the basis of a consensus of the multi-disciplinary team for all patients with CTEPH. Before treatment, the patient′s exercise tolerance and pulmonary artery flow parameters were evaluated. A comparative analysis of various parameters before BPA treatment and at the last BPA was conducted. 6-min walk distance (6MWD) was analyzed using the paired Wilcoxon test; N-terminal pro-brain natriuretic peptide (NT-proBNP), mixed venous oxygen saturation, mean pulmonary arterial pressure (mPAP), cardiac index (CI) and pulmonary vascular resistance (PVR) were compared using the paired-samples t-test. WHO functional class was compared using McNemar′s test. Results:Twenty patients with a total of 130 vessels underwent 46 sessions of BPA treatment. The postoperative 6-minute walk distance (6MWD) [447 (415, 485) m] showed a significant improvement compared to the preoperative baseline [389 (335, 470) m] ( Z=6.52, P<0.05), Postoperative mixed venous oxygen saturation (72.0%±1.9%) showed a significant improvement compared to the preoperative levels (64.0%±2.7%) ( t=2.14, P<0.05).Postoperatively, plasma NT-proBNP [(351.9±129.9) pg/ml], mPAP [(24.2±1.9) mmHg], and PVR [(3.0±1.4) WU] significantly decreased compared to preoperative levels [(982.5±426.2) pg/ml, (33±2.1) mmHg, (8.0±1.6) WU)] ( t=3.38, 1.22, 2.10, P<0.05 for all). Postoperatively, there was a significant improvement in WHO functional class (Ⅰ，Ⅱ，Ⅲ，Ⅳ: 14, 4, 2, 0 cases) compared to preoperative status (Ⅰ，Ⅱ，Ⅲ，Ⅳ: 0, 13, 5, 2 cases) ( χ2=20.17, P<0.05). Four cases of pulmonary artery dissection and one episode of hemoptysis occurred postoperatively, with no other complications reported. Conclusions:BPA can significantly improve exercise tolerance and hemodynamic parameters for residual PH after PEA. BPA is a relatively safe and effective treatment for residual PH after PEA.
