objective To study the relationships between TNF-β gene type in idiopathic dilated cardiomyopathy (IDC). Methods Eighty-six IDC patients were chosen as IDC group and 95 cases unrelated healthy people as control group in the First Hospital of Jilin University in 2008. The levels of TNF-β protein were detected with Enzyme-linked immunosorbent assay(ELISA ). TNF-β polymorphism were analyzed by polymerase chain reaction-restriction fragment length polymorphisms(PSR-RFLP). Results The levels of TNF-β protein in IDC patients[(1.876±1.013) μ/L] were significantly higher than controls[(1.018±0.645)μg/L], the difference being statistically significant (t=2.674,P<0.01). The frequency of TNFβ*2 genotypes in IDC patients[63.4%(109/172] was significantly higher than controls[47.9%(91/190)], the difference being statistically significant(OR=1.88, X2=6.78, P<0.05). Conclusions The TNFβ*2 allele might related to idiopathic dilated cardiomyopathy (IDC), can also be considered as one of susceptible genes of IDC

ObjectiveTo develop an experimental model of orthostatic hypotension (OH) after spinal cord injury (SCI) in rabbits and investigate the effect of tilting table exercise and Shengmaiyin on it. MethodsRabbit model of OH after SCI were induced by complete transection of spinal cord at the T5 spinal segment and raised to 60° head up tilt (HUT) on a tilting table. Tilting table exercise and Shengmaiyin were applied to different groups for 28 d from 4 days after operation. Systolic blood pressure (SBP) and pulse rate (PR) were observed with non-invasive sphygmobolometer of rabbit 3, 10, 17, 24, 31 d after the operation. Liquid chromatography with electrochemical detection(HPLC-ECD) was used to detect the concentrations of plasma norepinephrine (NE) and epinephrine(E) with horizontal position and HUT 60° on the 31st day. ResultsSBP with HUT 60° in rabbits of combined treatment group was significantly higher than that in rabbits of SCI group on the 24th day after operation,and the drop in SBP from horizontal position to HUT60° was significantly lower than that in rabbits of SCI group. SBP with HUT 60° in rabbits of exercise group and combined treatment group was significantly higher than that in rabbits of SCI group on the 31st day after operation. The drop in SBP from horizontal position to HUT 60° was significantly lower in rabbits of Shengmaiyin group, exercise group and combined treatment group than that in rabbits of SCI group on the 31st day after operation. The concentration of E and NE of SCI group, Shengmaiyin group, exercise group and combined treatment group was lower than that of sham group, but there was no significant difference among these groups. ConclusionThe treatment with tilting table exercise and Shengmaiyin can improve OH after SCI partially in rabbits without involving norepinephrine and epinephrine significantly. The period of treatment can be shorten when both therapies used together.

Objective To evaluate the effectiveness and safety of BiPAP non-invasive ventilation on COPD patients during acute exacerbation(AECOPD).Methods 20 COPD patients were ventilated using BiPAP non-inva- sive ventilation through a nose or mouth-nose mask.Their vital signs(RR,HR and BP)and arterial blood gases indi- cators(pH,PaCO_2,PaO_2 and SaO_2)before and after ventilation were monitored and the clinical effectiveness was ob- served.Results The vital signs and arterial blood gases indicators of 17 of the 20 AECOPD patients were improved. PaCO_2 was lowered,pH,PaO_2 and SaO_2 were elevated,and the difference before and after ventilation was statistically significant(P＜0.05).Conclusion BiPAP non-invasive ventilation can improve the vital signs and physiological in- dicators of AECOPD patients,relieve their respiratory muscle fatigue and prevent them from exacerbation of respira- tory failure,thereby lower the need for endotracheal inrubation.

Objective To analyze effect of balloon embolization therapy for traumatic carotid cavernous fistula (TCCF),so as to provide references for treatment of this disease.Methods A total of 21 patients with TCCF managed with balloon embolization from April 2006 to March 2012 were collected in the study.There were 17 males aged (32.3 ±5.4) years and 4 females aged (40.6 ±5.8)years.Perioperative clinical presentations and imageologic changes were observed as well as operative outcome was evaluated.Results After 3 months of follow-up,20 patients experienced successful detachable balloon embolization,but the other one patient had to have stent angioplasty due to the failure of the procedure.All patients had some improvements on clinical presentations after operation (P ＜ 0.05).Imageologic examination revealed that all patients had complete occlusion of TCCF following operation.In follow-up,one patient had a relapse,with total curative ratio of 95％.Conclusions Detachable balloon embolization is effective in treatment of TCCF.Presently,the technique is an optimal method for such kind of disease and is worthy of wide clinical use.

Radiotherapy is an important therapy for uterine cervical cancer and plays a great role in improving the outcome in uterine cervical cancer patients. The high frequency subject headings/subheadings in papers on radio-therapy for uterine cervical cancer in the past 10 years were analyzed by co-occurrence clustering analysis to dis-play the hot spots and a strategic coordinate figure was plotted to show the developing tendency of its hot spots in studies on radiotherapy for uterine cervical cancer in order to provide reference for its-related studies.

Epithelial ovarian cancer is the most lethal gynecologic malignancy, drug?resistance will eventually appear after re?peated intermittent chemotherapy. However, second?line chemotherapy only works on a few patients, new drugs with better efficacy and less side effects are needed. There are a number of promising results of molecular targeted therapy in recent clinical trials for patients with recurrent epithelial ovarian cancer, such as Bevacizumab, Olaparib, Pazopanib, etc. They have been demonstrated to improve progression?free survival of patients with platinum?resistant ovarian cancer, which might become a new strategy for such patients. In this review, we summarized the current status and progress of targeted therapy for recurrent epithelial ovarian cancer.

OBJECTIVE:To explore the optimal steaming time of Carapax trionycis during cleansing period,and to optimize and improve production technology of Carapax trionycis recorded by current Chinese Pharmacopoeia. METHODS:The mechanical processing replaced the artificial processing method in Chinese Pharmacopoeia. The content of protein and the appearance of Cara-pax trionycis were investigated after steaming for 30,60,90,120,180,240 min during cleansing period. The extract,decoction, ash content,appearance and property of Carapax trionycis decoction piece processed with vinegar were also investigated after cleansed Carapax trionycis decoction piece was processed by sand scalding and vinegar quenching method. RESULTS:The differ-ent steaming time obtained different quality of cleansed Carapax trionycis decoction piece and Carapax trionycis decoction piece pro-cessed with vinegar. Compared with decoction piece steamed for other duration,when the steaming time was 90 min,the content of protein in cleansed Carapax trionycis decoction piece was higher(31.16%),and its appearance was up to the requirement. Cara-pax trionycis decoction piece processed with vinegar had higher contents of extract and decoction(9.13%,11.39%)and lower con-tent of ash(66.29%),and its appearance was up to the requirement. CONCLUSIONS:Different steaming time have certain effect on the quality of cleansed Carapax trionycis and Carapax trionycis processed with vinegar,the optimal steaming time of Carapax tri-onycis is about 90 min during cleansing. The mechanical processing method maybe replace the artificial processing on Carapax tri-onycis for improving its production efficiency.

Objective Gynecologic minimally invasive surgery has become popular in the treatment of tumor therapy in re-cent years, but improper application can result in tumor metastasis.In this paper, we presented 6 uterine neoplasm cases of tumor me-tastasis after minimally invasive surgery and analyzed the causes and the preventive measures. Methods Retrospective analysis was made on the clinical data and pathology characteristics of the 6 uterine neoplasm cases of tumor metastasis after primary minimally inva-sive surgery in our department from January 1, 2013 to 2015 June 30, and related literature were reviewed. Results The ages of 6 patients were 39-52 years old.The primary operation methods included 2 cases of hysteroscopic myomectomy, 3 cases of laparoscopic myomectomy and 1 case of radiofrequency ablation.The pathological diagnosis after primary operations were 4 cases of uterine sarcoma ( low grade endometrial stromal sarcoma in 2 cases and leiomyosarcoma in 2 cases) who were found metastatic tumor at 3-16 months after primary surgery and finally died of the disease and 2 cases of uterine fibroids who were found metastatic tumor in abdominal cavity and puncture hole at 60 months and 108 months respectively after primary operation followed by a good prognosis after the second surgi-cal resection. Conclusion Owing to uterine neoplasm by hysteroscopy, laparoscopy often needs certain pressure and morcellation which may result in easy plantation of crushing tumor tis-sue or metastasis with circulation and puncture under pressure.Ra-diofrequency ablation lack of histopathologic diagnosis has heating effect which is inclined to speed up the spread and transfer of tumor cells once it is diagnosed as malignant.Therefore, clinicians should know the defects and risk of being lack of histopathologic diagno-sis, diagnostic curettage pathology and fast pathology to avoid tumor metastasis induced by minimally invasive surgery.

OBJECTIVE To explore the outcomes of CO2 laser assisted stapedotomy with artificial stapes prostheses in the treatment of advanced otosclerosis. METHODS Between January 2010 and January 2014, 15 patients (16 ears) diagnosed as advanced otosclerosis accepted CO2 laser assisted stapedotomy with artificial stapes implantation in our department. The averaged preoperative air conduction threshold of the speech frequency was 70.21 dB HL, the averaged bone conduction threshold was 38.49 dB HL, the averaged air-bone gap (ABG) was 31.72 dB HL. All cases were followed up for more than 6 months after operation. RESULTS All cases accepted auditory follow up after 6 months postoperatively. The speech frequency average air conduction threshold was 43.7 dB HL, the average bone conduction threshold was 28.95 dB HL, the average ABG was 14.75 dB HL. The ABG≤20 dB was achieved in 9 ears (56.3%) and ABG closure (≤10 dB) was achieved in 6 ears (37.5%). No cases appeared intractable vertigo, sensorineural hearing loss, secondary facial paralysis and other serious complications. CONCLUSION CO2 laser assisted technique reduced the probability of serious complications of stapedotomy, most patients with hearing level improved significantly. It's a safe, practical, relatively economical choice for advanced otosclerosis.
