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.

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.

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.

Cutaneous wound healing is a complicated multiatep process with numerous mediators that act in a network of activation and inhibition processes. Nonhealing chronic wounds decrease the quality of Life. Recombinant growth factors, currently used in clinic, fail to provide a sustained repair function at the wound due to their inadequate biological availability and transient half-time. Recent attention has focused on gene therapy, which might become a significant treatment modality for those wound healing pathologies refractory to other wound management approaches. This review discusses the potentials and limitations of current genetherapy for the treatment of wounds, current ongoing clinical trials, and possible future directions in this exciting field.

Cancer cells frequently share biological characteristics and energy metabolic processes distinct from normal cells. The specific metabolic phenotype was originally known as the Warburg effect. Researchers later discovered that cancer cells prefer to synthesize fatty acid de novo . Moreover, key enzymes involved in fatty acid synthesis and β-oxidation are overexpressed in tumor tissues, with low or without expression in normal tissues. Abnormal fatty acid metabolism is related to the survival and invasiveness of cancer cells, indicating that abnormal fatty acid metabolism provides the crucial components and energy sources of cancer cells. In recent years, the specific phenotype of abnormal fatty acid metabolism and the exploration of the role of this metabolic alteration in cancer biology and therapeutic strategies targeting the fatty acid metabolic pathways have become attractive focuses in cancer research. The role of active fatty acid metabolism in tumorigenesis and development, as well as the research progress in the development of the specific inhibitors, is reviewed in this paper.

Ligustrazine is one of the active ingredients of chuanxiong. Modern medical research indicated that ligustrazine had the effect of improving microcirculation, anti-inflammatory, anti-fibrosis, which showed the potential function of ligustrazine in the prevention and treatment of postoperative abdominal adhesions. The basic theory of traditional Chinese medicine (TCM) also believed that ligustrazine had the unique double effect of regulating both qi and blood. Therefore, ligustrazin had broad research and application prospects in the prevention and treatment of postoperative abdominal adhesions. This article reviewed studies of ligustrazine in the prevention and treatment of postoperative abdominal adhesions in recent years from four aspects, which were theoretical basis, clinical application, mechanism research and pharmaceutical dosage forms. It identified the research status and advantages of ligustrazine in the prevention and treatment of postoperative abdominal adhesions. It also pointed out shortages in the clinical application, such as unstandardized medication, small sample size study and etc. There were insufficient deep and clear studies in the research of mechanism. In the aspect of pharmaceutical dosage forms, the thinking should be expanded with innovation. It will provide basis and direction for research and application in the future, in order to further elucidate mechanisms in the prevention and treatment of postoperative abdominal adhesions as well as provide theory basis, research thinking and methods for the real display of advantages in TCM.
