Objective:To adopt the brain lesion model of mouse induced by overload aluminum to study the relationship between monoamine oxidase B disorder and neurodegeneration induced by overload aluminum(Al).Method:Aluminum overload models were established by injection of 3?l AlCl3 into lateral ventricle of miceeach day for 5d.The AlCl3 solutions injected in different modelswere with different concentrations and they were 0.125%,0.25%,0.5%.On d10,d20,and d30 after the final administration of AlCl3 solution,the learning and memory function of mice,pathomorphology of hippocampi,and MAO-B activity were determined.Results:Aluminum overload elevated MAO-B activity,caused karyopyknosis and loss of neurons in CA1 area of hippocampi,in dose-and time-dependent manners.Conclusion:The results indicate that neurodegeneration induced by Al toxicity may be related to the monoamine oxidase B homeostasis interfered by Al overload.

Raman bands of oleanolic acid were measured with laser Raman spectroscopy, and compared with that obtained fron IR spectroscopy. It was found that the corresponding characteristic bands of oleanolic acid can be identified in both speetroscopy.

Objective To investigate clinical characters of functional dyspepsia (FD) and organic dyspepsia (OD) and evaluate the Chinese management guideline of dyspepsia. Methods Three hundreds patients with epigastric dyspepsia symptoms received a series of examinations including a detailed investigation of symptoms, liver functions, upper gastrointestinal endoscopy and B ultrasound, and then they were divided into OD and FD groups in accordance with Rome Ⅱ criteria. Results 153 (51.0%) and 147 cases (49.0%) were ascribed to FD and OD respectively. FD occurred more often at the age of less than 40 ( P =0.006). The scores of such symptoms as bloating( P

Objective To study the mechanism and the nomenclature of the lumbar disk herniation associated with posterior bony edge separation of the vertebral body, based on its CT findings in transverse and sagittal planes. Methods 18 patients with lumbar disk herniation were evaluated with the CT scan and sagittal reconstruction. Results There were 19 lumbar herniated disks associated with separated posterior bony edge of the vertebral body which protruded into the spinal canal. There was bony defect filled with disk material. In the sagittal plane, the bony separation and the posterior edge of the vertebral body formed the “V” type defect at 15 levels, and 4 were irregular or triangular. 15 cases of the disc herniation had bony separations and 4 had bone connection with the vertebral body. There were bony defect and sclerosis on the vertebral body edge. Conclusion The main mechanism was the separation compression of the herniated disk on the posterior vertebral body. The bony separation was the secondary change. So the authors suggest that such anatomical pathologic changes be named as intervertebral disk herniation associated with posterior bony separation of the lumbar vertebrae.

Objective In order to study the structure-activity relationship of oridonin,Some derivatives of oridonin were synthesized and their cytotoxicity activity was evaluated.Methods Oridonin (Ⅰ) was isolated and purified by silica gel column chromatography.The derivatives were synthesized from oridonin through oxidation and acylation.All compounds were confirmed by spectrum analyses and their cytotoxicity was evaluated by MTT method.Results Six compounds were obtained and identified as: 14-acetyl-oridonin(Ⅱ),1,14-diacetyl-oridonin(Ⅲ),14-p-tolylsulfonyl-oridonin(Ⅳ),1-oxo-oridonin(Ⅴ),14-acetyl-1-oxo-oridonin(Ⅵ),14-p-tolylsulfonyl-1-oxo-oridonin(Ⅶ).Among them compounds Ⅳ,Ⅵ,and Ⅶ were new compounds.Five compounds showed better cytotoxicity than oridonin.Conclusion The cytotoxicity of 1oxo oridonin derivatives is first evaluated and shows the stronger cytotoxicity than oridonin.

The factors impacting the pregnancy rate and the live birth rate mainly include ovary function disorder and low endometrial receptivity, which can cause the difficulty in embryo implantation, early miscarriage and pregnancy failure. In recent years, researchers of the traditional Chinese medicine (TCM) have made active efforts in assisting IVF-ET, so as to achieve a great advance in improving the ovary reaction, treating the ovarian hyperstimulation syndrome (OHSS), improving the follicle, embryo quality and endometrial receptivity and protecting the fetus, which had been summarized in this article.

Purpose To study the clinicopathological features, immunophenotype and differential diagnosis of spindle cell rhabdomyosarcoma in adults (SRMS).Methods The clinical,pathologic and immunohistochemical features were evaluated in 9 cases of SRMS in adults.Results Nine cases of SRMS in adults were retrieved from the pathological archive of this hospital. 7 cases were male and 2 were female. Patients age ranged from 20 to 80 years (median,45 years). The head and neck region,including the right mandible, pharyngeal portion, nasopharynx, and left maxillary,was the most commonly affected area, accounting for 44% of the cases, followed by forearm, waist, thigh, leg and testis(1 case each). Tumor size varied from 2 to 14 cm (median 5.9 cm).Histologically, all the tumors were mainly composed of cellular bands and fascicles of atypical spindlE-shaped tumor cells with a variable number of spindled or polygonal rhabdomyoblasts.In addition, focal areas reminiscent of interstitial sclerosing were presented in 2 cases, and pseudovascular structures were noted in 2 cases, loosely myxoid stroma were detected in 1 case and small solid areas with mild pleomorphic tumor cells were present, but lacking bizarre pleomorphic rhabdomyoblasts. Immunohistochemically, the tumor cells were positive for vimentin, desmin, CD99 and MyoD1; Myogenin and MSA were positive in most of the cases (6/9 and 7/9 each); The remaining antibodies(S-100, CD34,CK and HMB-45) were all negative. Follow-up information was available in all the cases, ranged from 6 months to 4 years, revealed paravenous metastases of the peritoneal cavity in one patient with testis tumor and liver metastases in one patient with leg tumour. 4 patients developed local recurrences and 2 patients died of the disease.Conclusions SRMS is a rare neoplasm in adults,and most commonly occurs in male with preferential involvement in the head and neck region. It appears a more aggressive clinical course in adults. Morphologically, SRMS in adults should be differentiated from other spindle cell tumors.

Objective To evaluate the clinical efficacy of partial hepatectomy in treating intrahepatolithiasis. Methods The data of 63 cases with partial hepatectomy were retrospectively evaluated. Results All operations were successful. Mean hospital stay was 30.5d. Complications were found in 9 cases (14.3%), including 2 cases of sub-phrenic abacess,2 cases of biliary fistula,4 cases of wound infectiun,1 case of pleural effusion. Residual stones were found in 7 cases (11.1%) ,4 were in left hepatic lobe,3 were in right. 62 cases (98.4%) were followed for 6 months to 8 years. Stones recurred in 2 cases. Conclusion Partial hepatectomy is effective for the treatment of intrahepatoli-thiasis with low residual stone rate.
