Aim To establish an animal model of uterine leiomyoma for pathogenesis research and drug screen analysis.Methods Guinea pigs were treated with estradiol benzoate 100 ?g?d~(-1),twice a week,by intramuscular injection for 12 weeks.After the animal were killed,the uteri were dissected out and ultrathin sections were obtained.Compare to that of human being,pathohistologic characteristics were observed under the microscope.Results The uteri treated with estrogen were proliferated and deformated.Uterine nodules were observed in many of the tested animals.According to the results of pathohistology,these cells demonstrate the features of smooth muscle-like cells.Conclusion The uterine leiomyoma induced by estrodiol in guinea pig is similar to that of human being.It has been suggested that the animal model is valuable for pathogenesis research and drug screen analysis,although it still needs more evidence to be demonstrated.

Clinical studies have shown that trastuzumab combined with chemotherapy can significantly improve survival in treatment of HER2-positive metastatic breast cancer as well as in the neoadjuvant and adjuvant therapy for HER2-positive early breast cancer. In patients with HER2-positive and hormone receptor-positive metastatic breast cancer, adding trastuzumab to endocrine therapy improves treatment efficacy. Resistance to trastuzumab may be reversed by incorporating other targeted therapeutic drugs. Patients can still benefit from continuing trastuzumab after their disease progresses.

[Objective]To sum up Mr. Zhu Xiankang’s clinical experience in treating children multiple tourette syndrome with nourishing kidney to soothe liver and relieving dizziness to remove sputum. [Method] By expounding the reason and mechanism, treating rules and formula of children multiple tourette syndrome, as wel as analyzing typical clinical cases, it expounds Pro. Zhu Xiankang ’s experience in treating the said disease with his method. [Re-sult] In his view, the disease owes to excessive five sensations, wind sputum accumulated inside, with mechanism of deficient kidney and hyperactivity of liver, wind sputum blocking col aterals, should take nourishing kidney to soothe liver and relieving dizziness to remove sputum as basic method;he applied revised Dingchou Decoction to treat 1 case of multiple tourette syndrome; after 3m, the un-automomous spasm disappeared gradual y, the patient had good appetite and sleep, al symptoms were relieved, and he was cured. [Conclusion] Mr. Zhu Xiankang ’s clinical experience in treating children multiple tourette syndrome has enlightenment to pediatrics clinic.

OBJECTIVE:To study the effects of celastrol on the proliferation and apoptosis of human hepatoma HepG2 cells, and investigate its mechanism. METHODS:CCK-8 method was used to determine the cell activity 24,48,72 h after treated by 2, 5,10 μmol/L celastrol,and the proliferation inhibition rate and half inhibitory concentration(IC50)were calculated;flow cytome-try was conducted to detect the cell apoptosis rate and cycle change 24 h after treated by 2,5,10μmol/L celastrol,and the DMSO was used as negative control;rhodamine 123 staining method was used to determine the mitochondrial membrane potential 48 h af-ter treated by 2,5,10 μmol/L celastrol,and the DMSO was used as negative control;Western blot was adopted to detect the pro-apoptotic related genes Bax and B lymphoma 2(Bcl-2)protein expressions 0,12,24,36 h after treated by 5 μmol/L celastrol. RESULTS:2,5,10 μmol/L celastrol can inhibit cell proliferation,IC50 was 5.834 μmol/L. 2,5,10 μmol/L celastrol can induce apoptosis;5,10 μmol/L celastrol can block cell in G0/G1,S phases,compared with negative control group,with significant differ-ences(P<0.05 or P<0.01),and the above effects all showing certain concentration-dependent manner. 5 μmol/L celastrol can in-crease Bax protein expression and decrease Bcl-2 protein expression after cultured for 12,24,36 h,showing certain time-depen-dent manner;compared with 0 h,there was significant difference(P<0.05 or P<0.01). CONCLUSIONS:Celastrol can obvious-ly inhibit the proliferation of human hepatoma HepG2 cells and induce their apoptosis,and the mechanism may be related with strengthening mitochondrial permeability and promoting the release of apoptosis-inducing factor.

OBJECTIVE:To discuss the influence of Shanghai Guiding Principles of Clinical Use of Antibiotics Implementing Rules(Trial)(named Implementing Rules for short) on prophylactic use of drugs in patients underwent general surgery operation.METHODS:In retrospective study,inpatients of general surgery department in our hospital from Sep.2006 to Feb.2008 were divided into 3 groups(Group 1:6 months before Implementing Rules issued;Group 2:0～6 months after Implementing Rules issued;Group 3:7～12 months after Implementing Rules issued).The utilization of antibiotics was analyzed as well as its rationality.RESULTS:A total of 1 308 cases were enrolled.The utilization frequency of antibiotics was 3 463.Less than half of cases met the indication of antibiotics while the rate of drug sensitivity test was 1.2%.The treatment courses of 3 groups were(3.4?4.3) d,(3.3?2.9) d and(3.1?3.0) d.The proportions of rational drug use were 36.5%,35.1% and 40.7%.But the selection of antibiotics,drug combination and ADR report were not significantly improved.CONCLUSION:The issue of Implementing Rules has promoted the rational use of antibiotics in general surgery department.Further training and monitoring are needed.

Objective To report a pedigree of generalized atrophic benign epidermolysis bullosa (GABEB),a special type of junctional epidermolysis bullosa(JEB). This is the first case report in China. Methods The clinical, histologic, electron microscopic, and immunofluorescence changes of the disease were evaluated. Results Besides the symptom of inherited epidermolysis bullosa, the patient had special clinical manifestations such as atrophic alopecia and dental dysplasia. The disease was inherited in an autosomal recessive mode in this pedigree. Electron－ microscopy found the fissure in lamina lucida, accompaning with dysplasia and sparse hemidesmosome. Immunofluorescence study did not show BPAg2 in the basement membrane zone, indicating that mutation in the gene encoding BPAg2 leading to the disease in this family. Conclusions The case is diagnosed as GABEB, a special type of JEB. Although GABEB has its characteristic, clinical manifestations, electron microscopy and immunofluorescence study are important for confirmative diagnosis and classification, and will guide the study of mutation detection.

OBJECTIVE To study the classification and distribution of the ?-lactamases produced by Escherichia coli in diabetic patients.METHODS To detect the ?-lactamases produced by E.coli in diabetic patients with a multi-disk synergy test.RESULTS Forty-nine strains of 60 strains in our study produced the ?-lactamases with total positive rate of 81.67%,From them 5 strains were producing penicillinases,17 strains producing BSBLs(28.33%),and 27 strains were producing ESBLs(45.00%),no carbapenem-hydrolyzing ?-lactamases were detected.In 27 strains producing ESBLs,the sensitivities to the ceftazidime,aztreonam and cefotaxime were similar.CONCLUSIONS The types of ?-lactamases produced by E.coli in diabetic patients are mainly BSBLs and ESBLs,without carbapenem-hydrolyzing ?-lactamases;the sensitivities to the ceftazidime,aztreonam and cefotaxime are similar.
