ObjectiveTo study the relationship between the range of operations and the incidence of climacteric syndrom,the time of episode, degree and estrogen level in endometriosis after operations. MethodsThesexual hormone level was measured and climacteric syndrome was followed up after operation in 55 endometriosis. ResultsThe incidence of climacteric syndrom in oophorectomy was more frequent and earlier than partial oophorectomy. Meanwhile, the syndrome was much severe and the level of E2 was lower in the former group than those in the later one. ConclusionSo we should retain the ovary tissue and blood supply as much as possible. 6 months postoperation is suggested to be suitable to begin hormone replacement therapy. The dosage should be adviced to remain the blood hormone level just like one ovary does.

Objective To evaluate the efficacy and toxicity of weekly docetaxel and cisplatin in previously untreated patients with advanced non-small-cell lung carcinoma. Methods Between January 2002 and December 2003 ,34 patients with pathologically comfirmed advanced non-small-cell lung carcinoma who had not received treatment were enrolled. The mean age was under 66 years. The patients received intravenous infusions of docetaxel(25 mg/m2,dayl ,8,15) with dexamethasone premedication and cisplatin(25 mg/m2,dayl ,8,15) ,followed by a week of rest. The remedies which were less than 6 regimens lasted to disease progression or severe toxicity. Therapeutic effect was evaluated by CT scan every two courses . The patients were followed up for 24 months. Descriptive statistics and SPSSIO. 0 software were used to analyse the results. Results 34 patients finished 90 courses. The mean was 2. 6 courses. All patients were followed up. Two patients achieved complete responses, ten patients achieved partial responses, ten patients achieved stable disease. An objective response rate of 35. 29% (95% confidence interval 19. 25%-51. 33% )was obtained. Patients life quality was significantly improved. The median time to progression was 4. 1 months, and median overall survival was 11 months. The 1-year survival rate was 47. 06% , the 2-year survival rate was 11.76% . Toxicities were mild. Grade 3 to 4 neutropenia (11.76%), anemia (5.88%), hyponatremia (5.88%), alopecie (17.64%) and nausea/vomiting (5. 88% ) were observed. Conclusion Weekly Cisplatin plus docetaxel is an effective and well-tolerated regimen in chemo-naive patients with advanced NSCLC. Well-designed clinical trials should be conducted.

Objective:To evaluate the clinical efficacy of maintenance chemotherapy for patients who had local advanced non-small cell lung cancer (NSCLC) and was responsive to primary radiotherapy and chemotherapy. Methods:One hundred and twenty patients with stage ⅢA or ⅢB NSCLC received 4 cycles of chemotherapy combined with radiotherapy. The 63 patients who achieved certain remission were randomly divided into maintenance chemotherapy group(n=33) and control group(n=30). The patients in maintenance chemotherapy group (treatment group) received vinorelbine (20 mg/m2, d 1 and d 8, per 28 d a cycle) and those in control group were not given maintenance chemotherapy. The clinical efficacy, survival rate and adverse reaction of the two groups were evaluated. Results:There are a longer median time to progression(TTP) in treatment group compared with control group (8.5 month vs 5.0 month, P<0.05). The 1-and 2-year survival rates were 66.7% and 36.4% in the treatment group and 60.7% and 32.1% in the control group, respectively. The difference between the survival rates of two groups was not significant (P>0.05). Conclusion:Maintenance vinorelbine-based chemotherapy prolonged the median time to progression but had no effect on survival time in patients with local advanced NSCLC who responded to induction chemotherapy.

Objective To study the characteristics of the transcranial electric stimulation(TES)-elicited motor evoked potentials(MEP)recorded from different points of the diaphragm,and to determine the optimal record- ing site in the diaphragm.Methods One EEG electrode was placed subcutaneously in the midline of the skull as stimulation electrode and another EEG electrode was inserted into hard palate submucously as cathode in 30 male rats.And single square wave electrical pulse was used for stimulation.The stimulation intensity was 15 mA,the du- ration of the pulse was 0.2 ms,and the stimulating interval was 200 ms.The concentric needle electrode were insert- ed into the following eight sites:the medial,intermediate,lateral crura of the diaphragm,the junction of the posterior axilla line and the inferior border of the eleventh rib,the junction of the anterior axilla line and the inferior border of the ninth rib,the junction of the intermediate line of the clavicle and the inferior border of the eighth rib,the junction of the para-sternal line and the inferior border of the seventh rib,the pars sternalis.The MEP was recorded from each point,respectively.The optimal sites of the diaphragm MEP were found and recorded.Results The MEPs were re- corded from each of the 8 sites of the diaphragm in all the rats after TES.There was no statistically significant differ- ence among the latencies of every site.But the amplitude varied from 6.08?0.46 mV in maximum along the inferior border of the ninth rib at the anterior line of the axilla to the minimum of O.91?0.03 mV at the pars sternalis. Conclusion It is safer to insert the needle along the inferior border of the ninth rib at the anterior line of the axilla, because there was certain distant from the folding part of the pleura and the amplitude of the recorded wave at this point is maximal.

Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape, and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. In this review, we summarize the research findings over the past five years, and discuss the characteristics of the technique, the most recent progress and the perspective in the field of molecular imprinting of proteins.

Objective To analyze the imaging findings of coronary angiography using 64-slice row CT and investigate the difference of coronary artery's morphological characteristics between Uygur and Han populations.Methods A retrospective study was made to coronary CT angiographic images of 88 Uygur cases matched with 88 Han cases.The data were analyzed with X~2 test and paired Wilcoxon test.Results The coronary CT angiographic findings were different between Uygur population and Han population in the following aspects: there were 62, 18, and 8 cases with the left coronary artery originating from intra-sinus, para-sinus and extra-sinus location respectively in Uygur population, while there were 73, 14, and 8 cases in Han population respectively (t=8319, P<0.05).And there were 78,7, and 3 cases with the right coronary artery originating from intra-sinus, para-sinus and extra-sinus location respectively in Uygur population, while there were 82, 1 and 1 case respectively in Han population (t=6936, P<0.05).The incidence of the sharp marginal branch were 52 (52.09%) and 67 (76.13%) in the two populations respectively (X~2=5.8381, P<0.05).The cases with various malformations of coronary arteries were 16 and 6 cases in the two populations respectively(X~2 =5.1948,P<0.05).The cases with LCA variations were 28 and 49 cases in the two populations respectively(t =2692,P<0.05) and the number with RCA variations were 33 and 27 cases in the two populations respectively(2 =968,P<0.05).Conclusions There are lots of differences of the coronary artery morphology between the Uygur and Han populations.Firstly, these differences may be related to different patterns in coronary angiography.Secondly, these differences may be related to differences between Uygur and Han populations in the incidence and severity of coronary heart disease.

OBJECTIVETo evaluate the safety and efficacy and summarize the initial experience of transcatheter mitral valve repair (TMVR) for treating Chinese patients with severe mitral regurgitation.

METHODSIn May 2012, TMVR using MitraClip system was applied in 3 patients with severe mitral regurgitation. One patient suffered from with mitral valve prolapse and two with functional mitral regurgitation. The efficacy and complications of the procedure were analyzed.

RESULTSTMVR procedure was successful in all 3 cases. NYHA classification improved by 1 grade in 2 patients and 2 grades in one patient. The mean operation time was (105 ± 38) minutes and X-ray exposure time was (10 ± 4) minutes. Mean aortic pressure was increased from (62 ± 18) mm Hg (1 mm Hg = 0.133 kPa) to (75 ± 14) mm Hg, and mean left atrial pressure was significantly reduced from (15 ± 10) mm Hg to (9 ± 5) mm Hg immediately after the deployment of MitraClip. Three days after the procedure, left ventricular diastolic dimension decreased from (63 ± 11) mm to (59 ± 10) mm, left atrial dimension declined from (59 ± 11) mm to (51 ± 8) mm, and NT-ProBNP was reduced from (4292 ± 1137) mmol/L to (1187 ± 489) mmol/L. No complications occurred in all three cases.

CONCLUSIONSOur initial experience showed that TMVR using MitraClip system is safe and effective for patients with severe mitral regurgitation. However, the long term benefit of the procedure should be validated through follow up.
