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.

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

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 explore the new mode of industry-university-institute unification for pharmacy professionals. METHODS:The research-teaching interactive platform was established through the principles of“complementary advantages, shared interests and mutual benefits”. RESULTS:It changed the traditional teaching mode,and it ensured the professional plan-ning,curriculum development and training objectives of students based on“4 analysis,2 setting and 1 implementation”. CONCLU-SIONS:The opportunities for cooperation between students and employers were broadened and students’awareness of innovation and entrepreneurship was enhanced. It cultivates project-based pharmaceutical,technical and skilled personnel,solves the problem of industry-university-institute unification and has certain significance for the development of China’s pharmaceutical education.

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 construct the immune genes expression profile database of multiple sclerosis (MS) and to screen the high immune related candidate genes by using microarray analysis Methods Polymerase chain reaction (PCR) products on behalf of 484 immune related genes from mixed tissue library were assembled on the modified Oako glass slide The general RNA from MS patients and normal persons lymphocytes was transcripted to cDNA by RT PCR and labelled with cy 3 and cy 5 The two probes were mixed and hybridized with the above mentioned gene chips Scan array 4000 was used for scanning the hybridizing signals and GenePix Pro3 0 for date analysis Results Of the total 484 double genes monitored,22 genes of group one showed changes in expression level of the ratio outside 0 5 and 2.0;27 genes differ in group 2;72 genes change in group 3 With the same consistent gene ID of the double genes, the group one was 6,the group tow was 9 and the group three was 30 Conclusions These results show that the different expression of immune related genes might occur between MS patients and normal persons It might also afford a view of the changes that these genes should be probably related to the occurrence, development or progress of MS The cell immune related genes might be the important and most immune related genes involved in MS pathogenesis The results suggest the deeper insights into the mechanism,relapsing and treatment of MS

Objective: To assess the autonomic nervous impairment in chronic renal failure and its related factors. Methods: Forty adults were randomly selected including in patients in the nephrology ward and healthy subjects for routine medical examination. The subjects were classified into 4 groups: normal subjects(NS),normal renal function,nitremia, uremic patients. The time domain measurements of heart rate variability(HRV) and ambulatory blood pressure were analyzed simultaneously . Results: (1) There were significant differences as compared with normal subjects in the time domain measurements of HRV in uremic group. It decreased significantly when the patient was defined as end stage chronic renal failure. There were no significant differences between NS,normal renal function group and nitremic group. (2) Time domain measurements of HRV was significantly lower( P

Objective: To assess the autonomic nervous impairm ent in chronic renal failure and its related factors. Methods: F orty adults were randomly selected including in-patients in the nephrology ward and healthy subjects for routine medical examination. The subjects were classifi ed into 4 groups: normal subjects(NS)，normal renal function，nitremia， uremic patients. The time domain measurements of heart rate variability(HRV) and ambula tory blood pressure were analyzed simultaneously . Results: (1) There were significant differences as compared with normal subjects in the time domain measurements of HRV in uremic group. It decreased significantly when the patient was defined as end stage chronic renal failure. There were no significan t differences between NS，normal renal function group and nitremic group. (2) Ti me domain measurements of HRV was significantly lower(P<0.05) in uremia with renal hypertension than in uremia with normal blood pressure. Conclusio n: (1) Patients with chronic renal failure(HRV) have their cardiac auton omic nervous system impaired conspicuously in the course of uremia. (2) There is a positive correlation between cardiac autonomic nervous system impairment in p atients with CRF and renal function levels. Uremia itself is an independent fact or for the impairment of cardiac autonomic nervous system. (3) Renal hypertensio n with uremia may intensify the impairment of cardiac autonomic nervous system of the patients.
