RESUMEN
Objective To study the change of immune factor in COPD rats after intravenous injection of regulatory T cells.Methods Twenty-one SPF rats was divided into three groups at random,rat COPD model was built by smoking.We used magnetic bead isolation technic to separate CD4+CD25+ regulatory T cells.Regulatory T cells were cultured and injected into rats though rats' caudal vein according to different dose,5 × 104/mL,5 × 105/mL,5 × 106/mL respectively.Flow cytometry was used to analyze cell factors.ELISA was used to analyze IL-6 and CRP.Restlts Adding JJ316 or IL-2 into medium benefited the proliferation of CD4+CD25+ regulatory T cells.On the 20 th day,regulatory T cells CD4+CD25+ proliferation stopped by adding JJ316 or IL-2 respectively.Regulatory T cells were cultured and injected into rats though rat caudal vein according to different dose.The levels of CRP and IL-6 were decreased when rats were injected by CD4+CD25+regulatory T cell after one week.Conclusions Injection of regulatory T cells is helpful to control inflammation progression of COPD,so the increase of regulatory T cells of patients with COPD may decrease inflammation progression of COPD.
RESUMEN
Objective To investigate the incidence of anemia among patients with esophageal carcinoma undergoing radiotherapy, and to explore its influence on prognosis.Methods The data of 386 patients with esophageal carcinoma undergoing radiotherapy were collected retrospectively.The survival rates of the 1st, 3rd, 5th year were compared between the anemia group and non-anemia group.Analysis was carried on the impact factors of amenia on the prognosis and other clinical factors.Results The incidence of anemia before radiotherapy was 46.3 ％ (179/386), and the level of hemoglobin was 116 g/L (49-169 g/L).The incidence of anemia after radiotherapy was 74.2 ％ (286/386), and the level of hemoglobin was 98 g/L (45-152 g/L).The incidences of anemia between before and after radiotherapy were statistically different (x2 =61.915, P ＜ 0.001).The incidence of anemia before radiotherapy was associated with stage, Karnofsky score, BMI and the weight loss before treatment (P ＜ 0.05).The median survival time of the anemia group was 42 months, while that of the non-anemia group was 52 months, and the difference was statistically significant (x2 =5.002, P =0.025).There were 87.7 ％ of anemia patients got no treatment.Conclusions The prevalences of anemia before and after radiotherapy are high, and anemia before radiotherapy can decrease the survival rate in esophageal carcinoma patients.Methods should be taken to improve the haemoglobin level in order to increase the survival rate.
RESUMEN
Objective To explore the clinical value of therapeutic alliances of oviduct recanalization and video-laparoscope in the treatment of infertilitas feminis caused by multiple salpingemphraxis. Methods Sixty-seven patients with salpingemphraxis in 127 oviducts complicated with adhesions in fimbriated extremities were enrolled into our study. All the patients underwent separation of adherences in fimbriated extremities and neostomy using a video-laparoscope 2 to 3 days after selective oviduct recanalization. The therapeutic effects were retrospectively reviewed focusing on recanalization rate of proximal three segments, complete recanalization rate, and pregnancy rate and relevant complications during the follow-up period were analyzed. And patients with infertilitas feminis in the follow-up period underwent repeated salpingography to determine whether oviduct was repeatedly obstructed. Results The therapeutic alliance of oviduct recanalization and video-laparoscope were performed successfully in this cohort. Owing to the treatment of oviduct recanalization, recanalization rate of proximal three segments was 97.6% oviducts (124/127). Due to the alliance of oviduct recanalization and video-laparoscope, complete rate of oviduct were 98.4% (122/124). One year after operation, the pregnancy rate, ectopic pregnancy rate, and non pregnancy rate were 58.2% (39/67), 4.5% (3/67), and 37.3% (25/67), respectively. The patients with non pregnancy were composed by repeated oviduct obstruction in 25.4% (17/67) and non obstruction in 11.9% (8/67). Conclusion Therapeutic alliances of oviduct recanalization and video-laparoscope could be an effective method for the treatment of infertilitas feminis caused by multiple salpingemphraxis, and be helpful for the enhancement of pregnancy rate.

Objective To study the effect of BiPAP NIV in treating severe asthma that resists incretion.Method 38 asthma patients that resist incretion were selected with 19 patients given BiPAP NIV and the other 19 patients given oxyen by nasal catheter.We study the changes of blood gas analysis and days of hospitalization.Result After 4 days' treating,two group patients' PO_2 increase obviously and their dyspnea alleviate.In BiPAP NIV group,PO_2 is higher than that of the control group(P
