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 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.

ObjectiveTo evaluate the therapeutic effect of Salvia miltiorrhiza and ligustrazine as an adjuvant therapy in the patients with electric arcburns.MethodsFifty patients with electric arc burns were divided into 2 groups according to the random number table, with 25 in each group. The patients in the treatment group received intravenous infusion of 10 ml Salvia miltiorrhiza and ligustrazineinjection for 7 days in addition to the conventional therapies, and those in the control group only treated with conventional therapies.ResultsThe rates of wound healing in the treatment group were significantly improved at 7 days(25.7% ± 3.1%vs.21.3%± 3.0%;t=5.122,P=0.000) and 14 days(60.3% ± 8.6%vs.53.8% ± 10.8%;t=2.434,P=0.022) than the control group. While at 21 days, there was no significant difference between the two groups (99.4% ± 1.7%vs.98.7% ± 2.7%;t=1.163,P=0.265). The time to wound healing in the treatment group was significantly shorter than that in the control group (18.9 ± 2.5 dvs.20.3 ± 2.2 d;t=-1.216,P=0.020).ConclusionsSalvia miltiorrhiza and ligustrazine injections as an adjuvant therapy has a beneficial therapeuticeffect in patients with electric arc burns.

[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.

0.05). Conclusion:The rapid tooth movement is achieved impressively through dentoalveolar distraction osteogenesis, and tooth inclinations become largely associated with tooth movement.

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.

Objective To investigate the effect of propofol on the response of spinal cord to pain stimulation induced by intraplantar injection of formalin Methods Thirty SD rats of both sexes weighing 200 250g were randomly divided into six groups Pain stimulation was produced by subcutaneous injection of formalin (2 5%100?l) into the plantar region of unilateral front paw Group F received intraplantar injection of formalin only (n=6);group FP received intraperitoneal propofol 100?g?kg -1 10min after formalin injection (n=6); group PF received formalin injection 10min after intraperitoneal propofol 100?g?kg -1 (n=6); group P received intraperitoneal propofol 100?g?kg -1 only; group FS received intraperitoneal normal saline 10ml?kg -1 10min after formalin injection; and group S received intraperitoneal normal saline 10ml?kg -1 only 1 h after last injection (intraperitoneal or intraplantar) the animals were anesthetized and cervical spinal cord (where sensory nerves from front paw enter) was removed and sliced and examined for fos expression in the spinal cord using fos immunohistochemistry technique Results After formalin injection large numbers of fos like immunoreactive neurons (FLINs) were found in the ipsilateral dorsal horn Most of FLINs were confined to the medial part of outer area of laminal I and II Intraperitoneal propofol injected either before or after formalin stimulation significantly suppressed fos expression in all laminal (P

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.
