This paper reports the study and design of a visualization system of the ultrasonic rhinitis therapeutic apparatus with the function of endoscopic sinus. On Linux operating platform, we captured the video data of a video capture card that connected the endoscopic sinus using Video4Linux (V4L2) that was provided by the operating system. The video images were displayed by Qt. The visualization system solved the problem that the current ultrasonic rhinitis therapeutic apparatus had to rely on the large and expensive endoscopy equipment. And this simplified the doctors' operation, met the need of monitoring nasal cavity in the process of operating, greatly reduced the costs of treatment and would contribute to the promotion of the instrument. As a result, it has been tested that the nasal endoscopic image achieved by the system is clear and smooth, and fully meet the clinical needs of ultrasonic treatment of rhinitis.

By using spectroscopic techniques including 1H NMR, 13C NMR, 1H-1H COSY, HSQC, HMBC and TOF-MS, the compounds were identified as 3beta-hydroxy-24-nor-urs-4 (23), 12-dien-28-oic acid (1), ursolic acid (2), oleanolic acid (3), 3-O-alpha-L-rhamnosyl(1 --> 3)-beta-D-glucopyranosyl (1 --> 3)-alpha-L-rhamnosyl (1 --> 2)-alpha-L-arabinopyranosyl hederagenin 28-O-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranosyl ester (4), 3-O-[beta-D-xylopyranosyl (1 --> 4)-beta-D-glucopyranosyl (1 --> 4)] [alpha-L-rhamnosyl(1 --> 3)]-beta-D-glucopyranosyl (1 --> 3)-alpha-L-rhamnosyl(1 --> 2)-alpha-L-arabinopyranosyl hederagenin (5), separately. Among them, 1 is a new compound, and 2 is isolated from this plant for the first time.

Objective To investigate the expression of p53,VEGF,E-cad,CK20 and its clinical meanings in bladder transitional cell carcinoma. Methods The specimen microarrays and immunohistochemistry were applied to detect selected cancer-related protein expression in 45 cases of bladder TCC and 8 cases of normal control. Results Abnormal expression of p53,E-cad and CK20 were detected 100.0%,55.6%,55.6% respectively in bladder TCC group,which were expressed normally in control group with significant differences.However,there was no VEGF expression differences between those 2 groups (87.5% v.86.7%).Abnormal expression intensity of p53 and expression rate of E-cad were closely related to the pathological features.CK20 expression was co-related positively with disease staging rather than grading.VEGF played less role in co-relating with pathological features. Conclusions p53,E-cad and CK20 play an important roles in the development of bladder TCC,and VEGF plays less.Microarrays is suggested to detect a large scale of specimen for multiple proteins,it is effective.

Objective To investigate the clinical value of fast track surgery (FTS) in donor in liver transplantation.Methods The clinical data of 214 donors for liver transplantation at the Renji Hospital of Shanghai Jiaotong University from January 2006 to November 2011 were retrospectively analyzed.All donors were divided into FTS group and conventional group.From January 2006 to May 2009,73 donors who received conventional perioperative management were in the conventional group,and 141 donors who received FTS from May 2009 to November 2011 were in the FTS group.The recovery of the donors in the 2 groups was compared.All data were analyzed using the chi-square test or t test.Results The operation time,time to out-of-bed activity,time to postoperative exsufflation,time to bowel movement,and duration of postoperative hospital stay were (178 ±37) minutes,(1.6 ± 1.0) days,(2.9 ± 1.6) days,(3.1 ± 1.5) days and (5.9 ± 1.9) days in the FTS group,which were significantly shorter than (167 ± 33) minutes,(3.6 ± 1.4) days,(4.6 ± 2.3) days,(4.5 ± 1.4) days and (7.6 ± 1.5) days in the conventional group (t =2.115,77.138,6.504,6.913,6.970,P ＜ 0.05).The hospital costs of the FTS group and the conventional group were (1.8 ±0.6) × 104 yuan and (2.2 ±0.4) x 104 yuan,respectively,with a significant difference between the 2 groups (t =73.038,P ＜ 0.05).The volumes of operative blood loss of the FTS group and the conventional group were (130 ± 47)ml and (138 ± 46)ml,with no significant difference between the 2 groups (t =1.251,P ＞ 0.05).The rate of satisfaction of the donors in the FTS group and conventional group were 98.6％ (139/141) and 89.2％ (74/83),respectively,with a significant difference between the 2 groups (x2 =9.94,P ＜ 0.05).Conclusion FTS is safe,economical and can reduce stress,decrease hospital costs and promote early recovery of donors in liver transplantation.

ObjectiveTo evaluate the effect of radiofrequency therapy in the arthroscopic treatment of subacromial impingement syndrome.MethodsFifty patients with subacromial impingement syndrome treated arthroscopically were enrolled in the study.Preoperatively,the average visual analogue scale (VAS)score of all 50 patients was 5.3±1.8; the average UCLA score was 15.8±4.2; the average Constant score was 65.6±16.2; the average Simple Shoulder Test(SST) score was 6.5±3.3; the forward elevation was averagely 127.4°±40.1°; the external rotation was averagely 34.4°±23.1°; the internal rotation was averagely at L1 level.Patients were randomly assigned to radiofrequency group which received subacromial decompression and Topaz radiofrequency treatment,or control group which only underwent subacromial decompression.The VAS score,UCLA score,Constant score,and SST score were used to evaluate the clinical outcomes 3 weeks,6 weeks,3 months,6 months and 1 year after operation.The assessment of shoulder range of motion included forward elevation、external rotation and internal rotation.The clinical outcome data were compared between the radiofrequency group and the control group,as well as before and after operation within each group.ResultsAt the final follow-up,the average VAS score of all 50 patients was 0.4±1.1; the average UCLA score was 32.9±3.0; the average Constant score was 96.4±5.1; the average SST score was 11.3±1.2; the forward elevation was averagely 161.5°±13.7°; the external rotation was averagely 52.2°±10.9°; the internal rotation was averagely at T7 level.There were statistical differences between preoperative and postoperative indexes mentioned above.However,there were no statistical differences in indexes between the radiofrequency group and the control group at any time point.ConclusionThe Topaz radiofrequency therapy has no significant impact on clinical outcome of arthroscopic treatment of subacromial impingement syndrome.
