AimTo study the effect of extracts of ginkgo biloba leaves(GbE) on apoptosis in neuronal cells. Methods Primary cerebral cultures from rat fetus were used to observe the activity of neuronal cells and to determine the release of LDH and DNA gel electrophoresis. Results Gb E enhanced the activity of neuronal cells, decresed the release of LDH,and relieved the structural changes of nucleus and DNA fragmentation. Conclusion GbE can inhibit apoptosis in neuronal cells.

[Objective]To observe the clinical outcome of rotator cuff-reserved calcium deposit removal on extensive shoulder calcific tendinitis.To discuss if it is necessary to sacrifce the cuff integrity for a completely removal of calcium deposit.[Method]From Oct.2004 to Apr.2006,15 cases(15 shoulders)of extansive shoulder rotator cuff calcific tendinitis were treated with calcium removal under arthroseopy.Among them there were 6 males and 9 females with an average age of 44.7.The average pre-operative evaluation grade with Constant-Murley were 56(49~62).During the operation,the rotator cuff integrity were reserved in 8 cases and most of the deposits were removed with some calcium left in the reserved cuff layer.In the other 7 cases,complete deposit clearance were performed and the rotator cuff was repaired subsequently,average follow-up were 16.7 months(3~25).The Constant-Murley score and X-ray were taken after operation to evaluate shoulder function and the changes of remnant calcium were observed.[Result]13 cases reported significant pain dissolved and 2 reported pain relieved.The average postoperative Constant-Murley score of cuff-reserved group was 91(81~95),while the cuff-repaired group was 90.3(80~94).On postoperative radiograph,only 3 cases demonstrated remnant deposit,and disappeared within 3 months after operation.[Conclusion]Both of the two kinds of operations showed good clinical outcome.The rotator cuff-reserved calcium deposit removal has simplified operation techniques,less costs and fewer complications.It is unnecessary to sacrifice cuffintegrity for complete calcium removal.The remnant deposit could be absorbed when it is opened after operation.

[Objective]To evaluate the efficacy of nerve transfer for reconstructing the sensory function of the sole.[Method](1)Select saphenous nerve as donor nerve for the patients with the sensory loss beneath ankle level:dissect and cut off the saphenous nerve at the medialposterior aspect at upper-middle 1/3 of the leg and divide the gastrocnemius to expose the tibial nerve at the medialposterior aspect of the tibia, cut off partly nerve fibre of the tibial nerve and then end-to-end anastomose to the proximal end of the saphenous nerve. (2) Select sural nerve as donor nerve for the patients with sensory loss of sole only:dissect and cut off the sural nerve at the posterior aspect of the lateral malleolus, expose the tibial nerve at the posterior aspect of the medial malleolus and then cut off partly nerve fibre of the tibial nerve. The sural nerve was comdicted from the subcutaneous tunel at the anterior aspect of the Achilles's tendon to the posterior aspect of the medial malleolus and end-to-end anastomose to the partial nerve fibre of the tibial nerve. [Result]All the 9 cases were followed up from 1.5 to 2 years(mean 2 l months). The SCV(sensory conduction velocity) of the tibial nerve was ranged from 36.1 to 41.2 m/s, mean 38.3 m/s and the amplitude of wave (peak-to-peak amplitude) was a range from 7 to 15.3?V, mean 11.2 ?V by orthodromic electrophysiologic techniques. All 9 cases regained the sense of pain and touch of the sole.Three cases restored their sense of two point discrimination. All the patients expressed their satisfaction with their ability of walk and no muscles atrophy of the foot. The sensory loss in donor region was oberserved only lateral part of the foot beneath the lateral malleolus (sural nerve as donor nerve) and a small part of the anterior aspect of the ankle(saphenous nerve as donor nerve).[Conclusion]Nerve transfer can reconstruct the sensory function of the sole effectively.

OBJECTIVE:To study the effects of modern decoction method vs. traditional decoction method on decoction rate and decoction quality. METHODS: The advantages and disadvantages were compared between the two decoction methods through analysis on the whole decoction process and the storage of the decoction before oral administration taking major components or active components as parameters. RESULTS: As compare with traditional decoction method, the modern decoction method had more advantages for in which the operation is standard, the contents of active components were high, and the quality control can be performed from many ways. CONCLUSION: The modern decoction method deserves to be popularized.

At present, a number of scientific research achievements has been formed. Scientific achievement is the crystallization of great efforts from scientific workers, and it's also the valuable treasure of human civilization. Standardization is an important way to promote the international communication of Chinese medicine, and it's significant in boosting China's scientific and technological progress, improving market competitiveness and promoting international trade. Transformation of scientific research to the guideline is not only beneficial to improving the technology content of the standard, but also to the conversion from scientific research achievements into productivity. Therefore, only by absorbing the advanced scientific and technological achievements, reproducing the theory of traditional Chinese medicine (TCM) and medical technology in standard form, can make TCM keep pace with the times. This study preliminarily explores for the method to transform scientific research achievements into guideline, in order to provide reference for the future technical specifications, thus to further the development of TCM.

Objective: To study the clinical manifestations of the head and neck angiosarcoma and the re-lationship of the staging with clinical treatment and prognosis. Methods: The clinical data of 21 patients with head and neck angiosarcoma treated in our hospital between January 1993 and January 2008 were retro-spectively analyzed. By studying the medical records of all patients and reviewing the related literatures, we discussed the clinical manifestations of these patients and the relationship of staging with clinical treatment and prognosis of head and neck angiosarcoma based on soft tissue sarcoma staging of AJCC2002' 6th. SPSS 17.0 software was used for statistical analysis. We calculated the survival rate using Kaplan-Meier method and compared the survival curves using log rank test. Results: Among these 21 cases, 10 were treat-ed with non-combined treatment, and the other 11 cases were treated with combined treatment. There were 6 stage Ⅰ cases, 3 stage Ⅱ cases, 1 stage Ⅲ case, and 11 stage Ⅳ cases. The 1-, 3-, 5- and 10-year total sur-vival rates were 72.2%, 41.3%, 27.5% and 13.8%, respectively. The average time of recurrence or metastasis was 4 months. Twelve cases had local recurrence (accounting for 57.1%), and 11 cases had distant metasta-sis (accounting for 52.4%). The metastatic sites included lymph node in 5 cases, lung in 4 cases, liver in 1 case, and bone in 1 case. Different treatment modalities (χ~2=8.31, P=0.004) and tumor staging (χ~2=9.74, P=0.002) were prognostic factors. Conclusion: There are no unified treatment strategies for angiosarcoma of the head and the neck. The overall prognosis is still not ideal. Biological treatment has been applied to clinical practice. Preoperative combined treatment has positive results. Tumor staging is an important factor affecting the prognosis. Surgery-based combined treatment can improve patient survival.

Objective To investigate the influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.
