Objective To study the surgical techniques with keyhole operation for treatment of the huge intracranial meningioma located in the frontal skull.Methods 39 cases of huge intracranial meningioma were removed by microsurgery with supra-eyebrow approach keyhole operation.Results 39 cases of meningioma were totally removed.There was no associated morbidity,mortality or exacebation in all cases.Conclusion It suggests that keyhole microsurgery may provide maximum efficiency to remove the huge intracranial tumor located in the frontal skull and minimum invasiveness.However,it is very important to choose indication properly,to prepare sufficienctly before operation,and to operate with proficient skill of microsurgery.

To evaluate the effects of Shenmai Huoxue Decoction (SMHXD) on early diabetic peripheral neuropathy (DPN) in rats.

Objective To evaluate the effects of traditional Chinese medicine likeDansen and western medicine in treating traumatic brain edema (TBE). Methods A total of 130 Wistar rats were divided randomly into six groups: Group A (normal contrast group), Group B (operation group), Group C (western medicine treatment group, WM group), Group D (western medicine and salvia injection), Group E (western medicine and Honghua injection) and Group F (western medicine and Sanqi injection). The model of brain edema was established by liquid nitrogen treatment to assay whole blood viscosity, water content and Even blues (EB) in brain tissues and to observe the content and pathologic changes of endothlin (ET) in plasma. Results Whole blood viscosity of Groups D, E and F was lower than that of Group B (P0.05). Water content and EB in brain tissues and ET of plasma in Groups C, D, E and F were lower significantly than those in Group B (P

To investigate the effects of traditional Chinese compound recipe Yiqi Zengmin (YQZM) formula on expression of glucose transporter 4 (GLUT4) in skeletal muscle of rats with type 2 diabetes induced by high-fat diet combined with low-dose-streptozotocin injection.

Objective To investigate the relationship between the nerve function and the sorbitol concentrations of erythrocyte and sciatic nerve, and to evaluate the effects and mechanism of a formulae of Chinese medicine, Shen Mai Huo Xue Yin (a decoction, it ingredients including ginseng, tuber of dwarf lilyturf and safflower) on diabetic peripheral neuropathy (DPN). Methods The rats were divided into 3 groups: normal rats, diabetic rats and diabetic rats treated with Shen Mai Huo Xue Yin. The diabetes of rats was induced by streptozotocin intraperitoneally. Motor nerve conduction velocity (MNCV) of sciatic, sensory nerve conduction velocity (SNCV) of caudal nerve and the H reflex were detected with evoked electromyogram; The sorbitol concentrations of erythrocyte and sciatic nerve was measured by spectrophotography. Results The sorbitol concentration of erythrocyte was positively correlated with that in the sciatic nerve, and the sorbitol concentration of erythocyte and sciatic nerve were negatively correlated with SNCV and positively with H reflex. The SNCV reduced significantly and the sorbitol concentration of both erythrocyte and sciatic nerve increased significantly in diabetic group as compared with those in normal group. The SNCV and sorbitol concentrations of sorbitol both erythrocyte and sciatic nerve in diabetic group were significantly improved after treated with Shen Mai Huo Xue Yin. Conclusion The sorbitol concentration in erythrocyte reflects the level of that in sciatic nerve and the lesion degrees of DPN. Shen Mai Huo Xue Yin alleviates the lesion of DPN in the early stage.

The intra-tumor MTX concentration was measured in 12 patients with cerebral gliomas and 31 patients of malignant gliomas were treated with intracarotid infusion of papaverine and bis-chloroaitrosourea (BCNU). After intracarotid infusion of papaverine to open up the blood-brain-barrier (BBB), the MTX concentration within tumor tissues was 1854? 512ng/gram, which higher than that without papaverine infusion, which was 1020? 512ng/gram. The diagnosis was glioblastoma in 21 patients and anaplastic astrocytoma in 10. They received the infusion for a mean of 2.1 times with 250mg BCNU each. The mean survival time was 101.6? 32.7 weeks, with 104 weeks of median survival time. Fourteen were still living, including 11 glioblastoma and 3 anaplastic astrocytoma. Of those, four have lived over three years. We considered combination of papaverine and BCNU infusion for chemotherapy of malignant cerebral glioma is simple, safe and effective, so long as tumors were susceptible to the chemotherapeutic drugs.

Objective To detect the expression of BAT2L protein in developmental brain of rats.Methods Expression,distribution and location of BAT2L protein in developmental brain rats on embryonic day 18,postnatal days 1,7 and 15 and in adult at different time points were detected by Western blotting analysis,immunohistochemistry and immunofluorescence,respectively.Results Western blotting showed that the BAT2L protein expression level was higher in brain of rats on embryonic day 18,postnatal days 1 and 7 than on postnatal day 15 and in brain of adult rats.Immunohistochemistry and immunofluorescence showed that the BAT2L protein was distributed and located in cell membrane and cytoplasm of neurons but not in nuclei and extra-cellular space.Positive neurons were widely distributed in cerebral and cerebellar cortex,hippocampus and cerebral ganglion.The morphology of neurons was significantly different in newborn and adult rats.Positive prominences and branches of certain neurons were found in brain tissues of newborn rats but hardly in those of adult rats.Conclusion BAT2L protein is specifically expressed in cell body,membrane and prominence of neurons in brain of rats.

Objective To observe the removal of tumor necrosis factor-? (TNF-? ), interleukin-6 (IL-6) and endothelin-1 (ET-1) in continuous renal replacement therapy (CRRT) on hemorrhagic fever with renal syndrome (HFRS) patients, and investigate the effect of inflammatory mediators on HFRS. Methods A total of 40 patients with moderate or more severe HFRS were divided into two groups randomly. Continuous venous-venous hemofiltration (CVVH) was applied to the 20 cases in CVVH group, and hemodialysis (HD) was applied to the 20 cases in HD group. The levels of TNF-? and IL-6 were measured by enzyme-linked immunosorbent assay (ELISA), and ET-1 level was measured by radioimmunoassays (RIA). Results ① In comparing CVVH and HD groups, the days of oliguria (3.0?2.1, 6.0?3.4), incidence of complications (25%, 40%), and mortality (15%, 25%) had significant differences (P0.05). ④ In CVVH group, IL-6 and ET-1 could be detected constantly in filtrate, but TNF-? was not detectable. TNF-?, IL-6 and ET-1 were not detectable in dialysate. Conclusion Continuous blood purification can remove plasma inflammatory mediators. Therefore, it is helpful in recovering renal function, improving the prognosis of HFRS, and decreasing complications and mortality. CVVH is one of the best methods to treat HFRS.

Objective To study the dynamic changes and clinical significance of D-D, t-PA and PAI in patients with acute renal failure during the process of different methods of blood purification. Methods Thirty-seven ARF patients were divided into three groups: HD group, HDF group and HF group. Plasma D-D level, t-PA and PAI activity were determined 1 hour, 4 hours before and after treatment. Normal control group consisted of fourteen healthy people. Results ① Plasma D-D level and PAI activity in ARF patients were obviously higher than those in control group, while t-PA activity was lower(P0.05). ③ After 4 hours of the treatment, compared with HD group, HDF and HF groups had significant difference in plasma D-D level, t-PA and PAI activity(P
