OBJECTIVE:To compare the contents of triterpenoids,polysaccharides and heavy metals in Ganoderma lucidum sporule powder and Ganoderma lucidum.METHODS:The triterpenoid compounds in Ganoderma lucidum sporule powder and Ganoderma lucidum samples were analyzed by HPLC;five heavy metals in the samples were determined by ICP-MS and the polysaccharides were quantified by anthrone-sulfuric acid method.RESULTS:There were significant differences beween Ganoderma lucidum sporule powder and Ganoderma lucidum in the HPLC characteristic chromatogram of triterpenoid compunds.The total content of polysaccharide in Ganoderma lucidum sporule powder was higher than in Ganoderma lucidum sample.However,the five heavy metals in the two materials showed no marked differences.CONCLUSION:This study provides theoretical basis for the pharmacological difference between Ganoderma lucidum sporule powder and Ganoderma lucidum.

Peripheral blood gene expression profiling represents the pattern of expression of all genes in peripheral blood cells.By comparing the different gene expression of peripheral blood between cancer patients and healthy control or patients with alternative types of tumors,we can draw genes of different expression and further analyze the characteristic gene expression profiling to assist diagnosis and treatment.There have been remarkable advance in study of peripheral blood gene expression profiling in head and neck tumors,chest tumors,abdominal tumors,urinary tract and male reproductive system tumors,gynecological tumors and so on,which lay a foundation for further clinical applications.

OBJECTIVE: To investigate the growth inhibition and apoptosis of BGC-823 gastric cancer cells induced by Oridonin and its mechanism. METHODS: The Oridonin-treated BGC-823 cells were detected using MTT, transmission electron microscopy (TEM), TUNEL and flow cytometry (FCM) etc. RESULTS: Oridonin(16, 32, and 64 ?g?mL-1) significantly inhibited the proliferation of BGC-823 cells in dose and time dependent manner, with the inhibition rates at 68.5%, 90.8%, and 94.7%, respectively within 24, 48, and 72 h after treatment with 64 ?g?mL-1 Oridnin. When treated with 32 ?g?mL-1 Oridonin for 2 h,mitochondria and endoplasmic reticulum were proliferated and swelled under TEM; At 8 h,vacuolization of mitochondria and endoplasmic reticulum were noted, the internal structure disappeared, and the nuclear chromatin margination vacuolization were in typical apoptosis change; At 24 h, BGC-823 cells were arrested at G2/M phase, and the apoptosis rate was 37.8% under FCM. CONCLUSION: Oridonin inhibiting proliferation and apoptosis of BGC-823 cells maybe related to G2/M phase arresting, and Oridonin induce apoptosis of BGC-823 cells may through mitochondria or endoplasmic reticulum apoptosis pathway.

Objective To investigate the antioxidant activity of Enteromorpha prolifera by ABTS radical scavenging assay in vitro and provide scientific basis for exploitation of Enteromorpha prolifera.Methods The antioxidant activities of extracts by different solvents from Enteromorpha prolifera and water extracts from different Enteromorpha prolifera samples were investigated by ABTS radical scavenging assay.Moreover,the antioxidant ability of the water extract from Enteromorpha prolifera was evaluated by using caffeic acid and ascorbic acid as positive control standards.Results The water extract from Enteromorpha prolifera provided the highest radical scavenging activity,and the antioxidant capability of 1mL of water extract from Enteromorpha prolifera was equivalent to 1mL of 2.55 10~(-3) mg?mL~(-1) caffeic acid or 1mL of 2.89?10~(-3)mg?mL~(-1) ascorbic acid.However,the extraction methods,dry sample or not and different kinds of Enteromorpha prolifera samples had certain influence on the antioxidant activity of water extract from Enteromorpha prolifera. Conclusion There are abundant antioxidant compounds present in the aqueous extract of Enteromorpha prolifera,and it can be exploited as latent oxidation inhibitor.

Subarachnoid hemorrhage (SAH) is a common cerebrovascular disease,its disability and mortality rates are higher.It has been confkmed that early brain injury (EBI) and cerebral vasospasm (CVS) are the major pathophysiological mechanisms of causing neurological dysfunction and death after SAH.There are a variety of factors of causing CVS and EBI,including nitric oxide,endothelin,oxyhemoglobin,and proinflarnmatory cytokines.A large number of animal experiments and clinical research have confrmed that statins have neuroprotective effects.This article reviews the neuroprotective effects and its mechanisms of statins in SAH

ObjectiveTo analyze the different effects of spiral progress method and traditional method used in computer teaching in TCM colleges and universities.MethodsStudents were divided into the groups of spiral and traditional. At the end of the course, students would have a course examination.Results Students in spiral group got better scores than students in traditional group (P<0.05).Conclusion Using spiral progress method in computer teaching in TCM colleges and universities can help students develop the right thinking model and scientific learning method. It can also improve students’ ability to use computer knowledge in TCM study and research.

Objective To evaluate the clinical effect of transcatheter ethanol embolization of bilateral uterine artery as a treatment for fibromyoma. Methods Twenty one women with uterine fibromyoma underwent femoral artery puncture and transcatheter uterine artery embolization. Free flow bilateral artery embolization with ethanol were performed on 16 cases, three women undergoing unilateral embolization, and gelatin sponge were used in 2 cases. Results All cases were observed with a follow up of 3 to 64 months (mean 25 months) after the treatment. Nineteen women infused with ethanol were reported noticeable symptomatic improvement, including fifteen women with complete resolution of symptoms. Two women embolized with sponge exhibited clinical response at 2 and 5 months after the procedure, respectively. The marked diminution of tumor size (40%-90%) was sonographically demonstrated. No severe complications were discovered in all 21 cases. Conclusion Uterine artery embolization represented a promising new method of treating fibroids. It had safe and good clinical results. Further investigation would be required to assess its long term effect.

Objective To study and evaluate the inhibitory role of ?-carboxyglutamic acid(Gla)in the Gla domain of prothrombin in the formation of calcium oxalate crystals. Methods The addition of morpholine and formaldehyde to the solution of prothrombin caused the conversion of 8 Gla to ?-methyleneglutamic acid (8?-MGlu)or 2 Gla to ?-methyleneglutamic acid(2?-MGlu) ,the inhibitory activity of which to calcium oxalate crystallization was detected with seeded crystallization technique. Results The conversion of Gla to ?-MGlu leads to the decreased inhibitory activity of prothrombin to calcium oxalate crystallization,the inhibitory index being decreased from normal 14.2 to 12.8 of 2?-MGlu or 5.0 of 8 ?-MGlu prothrombin respectively. Conclusions Gla in prothrombin may play an important role to inhibit the formation of calcium oxalate calculi.

Objectiv To investigate the expression and clinical significance of CA125 and CA15-3 in human breast cancer. Methods Radioimmunoassay method was used to determine the serum levels of CA125 and CA15-3 in 80 patients with breast carcinoma, 60 patients with benign breast diseases and 80 normal adults. Results The levels of serum CA125 and CA15-3 in patients with stage Ⅲ-Ⅳ breast carcinomas were significantly higher than those in patients with benign breast diseases,normal adults and stage Ⅰ～Ⅱ breast cancer patients (P0.05). Conclusion CA125 and CA15-3 are helpful to diagnose breast cancer, and can serve as a biological marker for monitoring tumor progression and evaluating prognosis in breast cancer.
