Objective To observe the clinical efficacy of PHENIX electrical stimulation in preventing complications after missed abortion.Method A thousand patients receiving uterine cavity operation on missed abortion were randomized into two groups, 500 cases in each group. Patients in the two groups were asked to orally take Estradiol valerate, successively for 3 d prior to the operation. Right after the operation, the treatment group started to receive electrical stimulation at Guanyuanshu (BL 26) and Guanyuan (CV 4) via PHENIX USB 4/8 neuromuscular stimulation therapeutic apparatus, together with conventional preventive anti-inflammatory treatment; the control group only received the conventional preventive anti-inflammatory treatment after the operation. The colporrhagia duration and the resumption of menstruation in the two groups were observed, and the menstruation, postoperative adhesion ratio and adhesion rate were compared between the two groups.Result There were significant differences in comparing the duration of colporrhagia and the time of the resumption of menstruation after the operation between the two groups (P<0.05); there were significant differences in comparing the postoperative menstruation, intrauterine adhesion ratio and adhesion rate between the two groups (P<0.05).Conclusion PHENIX electrical stimulation can shorten the time of colporrhagia after missed abortion, promote the resumption of menstruation, and effectively prevent intrauterine adhesions.

Objective To discuss the therapeutic effect of chemoradiotherapy on 74 patients with early stage nasal NK/T cell lymphoma and their prognostic factors. Methods 74 patients with early nasal NK/T cell lymphoma that were treated in Shanxi Cancer Hospital from January 2005 to November 2013 were analyzed retrospectively. Among them, 28 patients received radiotherapy alone, 10 patients received concurrent chemoradiotherapy and 36 patients received alone. In 36 patients with chemotherapy, 25 cases were treated with CHOP (cyclophosphamide+doxorubicin+vincristine+prednisone), 4 cases were treated with DICE (dexamethasone + etoposide + cisplatin + isofosfamide) and 7 cases were treated with L-asparaginase +dexamethasone+ifosfamide+methotrexate + etoposide. According to Ann Arbor classification, 60 patients were stage Ⅰ and 14 patients were stage Ⅱ. Kaplan-Meier test was used for survival analysis, log-rank method was used for single factor analysis, and Cox proportional hazard model was used for multi factor analysis. Results All patients completed the treatment. 24 patients were died. 3-year overall survival (OS) rate was 72.5 %. The OS rate in simple radiotherapy group was 92.7 %, simple chemotherapy group was 62.3%, and the concurrent chemoradiotherapy group was 79.1%. The OS rates in simple radiotherapy and simple chemotherapy groups had statistical difference (χ2 = 10.676, P< 0.05), The difference in the simple radiotherapy and concurrent chemoradiotherapy groups was not statistically significant (χ2= 2.019, P> 0.05). In radiotherapy alone group, the rates of complete remission (CR), partial remission (PR), stable rate and progress rate of disease were 89.3%(25/28), 7.1%(2/28), 3.6%(1/28), and 0;in chemotherapy alone group, they were 55.6 % (20/36), 25.0 % (9/36), 8.0 % (3/36), and 11.1 % (4/36); in concurrent chemoradiotherapy group, they were 80.0 % (8/ 10), 10.0 % (1/10), 0, and 10.0 % (1/10), respectively. There was significant difference between radiotherapy group and chemotherapy group (χ2 = 8.584, P< 0.05); there was no significant difference between radiotherapy group and concurrent chemoradiotherapy group (χ2=0.556, P>0.05). Single factor analysis showed that age, ECOG score, B symptoms, Ann Arbor stage, IPI and treatment options were related to the prognosis. Multivariate analysis showed that age, ECOG score and Ann Arbor stage were independent prognostic factors. Conclusions As the main treatment method of early stage nasal NK/T cell lymphoma, radiotherapy can obtain good short-term curative effect and long-term curative effect. Age, ECOG score, B symptoms, Ann Arbor stage, IPI and treatment options are related to survival prognosis. Age, ECOG score and Ann Arbor stage are the independent prognostic factors.

Objective To compare the effect of emergency percutaneous transluminal coronanry angioplasty and thrombolytic therapy (PTCA) in acute myocardial infarction (AMI). Methods 52 cases of AMI were treated by emergency PTCA while 58 cases of AMI were treated by thrombolytic therapy, we then compared the clinical effect between two groups both in hospital and the follow-up period. Results In the emergency PTCA group, 3 cases died while 49 cases were successful (success rate 94.2%) and the average staying in hospital was 14.6 d. In this group the left ventricular ejection fraction (LVFT) was 45.5%?4.3%. During the follow-up period of 2～18 months, 3 cases of angina pectoris occurred again and 3 case accepted the treatment of selective PTCA in the emergency PTCA group. In the group of thrombolysis, 8 cases died while 50 cases were successful (the ratio of success rate 86.2%) and the average staying in hospital was 26.4 d. In this group the LVFT was 37.6?6.2. During the follow-up period of 2～18 months, 17 cases of angina pectoris occurred again and 17 cases accepted the treatment of selective PTCA in the thrombolysis group. Conclusion The infarct related arteries (IRA) can be revascularized with emergency PTCA in AMI. The treatment of emergency PTCA can reduce the ratio of sudden death and the days in-hospital ( P
