Objective To evaluate the effect of embelin combined with paclitaxel on the inhibition of A 549 lung cancer cell proliferation and tumor growing in tumor bearing nude mice. Methods The anti-proliferation efficiency of embelin combined with paclitaxel were evaluated by MTT assay, and A 549 cell apoptosis were evaluated by lfow cytometry. A 549 cells were xenografted in mice to establish the animal model, which were used to evaluate the effect of anti-tumor. Results compared to saline group、embelin group and paclitaxel group, the (paclitaxel+embelin) group could inhibit the growth of A 549 cells effectively(P<0.05). The embelin combined with paclitaxel induced the apoptosis of A 549 cells more effective than paclitaxel alone. The (paclitaxel+embelin) group significantly inhibited the growth of tumor tissue. Conclusion the paclitaxel can inhibit the growth of A 549 cells, the embelin can induce the apoptosis of A 549 cells, and the combination of paclitaxel and embelin may be a potentially effective treatment for lung cancer.

Objective To investigate Ureaplasma urealyticum in cervical specimens of gynecologic check-up population and female sex workers(FSW)and its biovars and serotypes.Methods The gynecologic check-up patients and female sex workers were screened using Uu liquid selective medium.The positive cases were then divided into biovars and serotypes by the means of PCR.Results Ninety-eight FSW and164gyne-cologic check-up patients were investigated.In the FSW group,89cases(90.8%)were positive in culture,in-cluding biovar164cases(71.9%),biovar1+27cases(7.9%),biovar218cases(20.2%).In71biovar1positive cases,biovar1+2and co-infection of serotypes of biovar1were defined as mixed infection.Infection with single serotype of biovar1was defined as simple infection.So in71biovar1positive cases of FSW group,there were17mixed infections(23.9%)and54simple infections(76.1%).Simple infections were then subdivided into serotypes,including serotype117cases(31.5%),serotype322cases(40.7%),and serotype615cases(27.8%).In gynecologic check-up group,104cases(63.4%)were culture positive,in-cluding biovar197cases(93.3%),biovar27cases(6.7%).In97biovar1positive cases,there were11mixed infections(11.3%)and86simple infections(88.7%).In86simple infections,there were serotype122cases(25.6%),serotype337cases(43.0%),and serotype627cases(31.4%).Conclusions The posi-tive rate of Uu in FSW is higher than that of gynecologic check-up population(P

The increasing identification of genetic causes for epilepsy over the recent years improves the understanding of the underlying epileptog enic process,and allows for the possibility of directed therapeutic approaches.An ideal antiepileptic therapy consists of a drug which is able to influence the functional changes caused by a specific pathogenic variant.In this review,we describe the current precise medicine approaches in genetic epilepsies.Currently established or investigated precise medicine treatments include the ketogenic diet in patients with glucose transporter typel (GLUT1) deficiency,sodium channel blockers in patients with KCNQ2 mutations,and mechanistic target of rapamycin (mTOR)-inhibitors in patients with SCN2A and SCN8A mutations.These predominantly represent already available treatments that were repurposed for use in epilepsy.The development of new therapeutic agents aiming at targets identified in genetic epilepsies will advance epilepsy treatment considerably.

Standardization of residency training aims to improve the overall quality of residents and bring up high-quality medical students.Research capabilities and innovative spirit of young physicians play important roles in the sustainable development of hospitals.This article describes the experience in strengthening research training in the United States residency program,provides recommendations to resolve the problems of our residency standardized training and new ideas for the domestic medical institutions to strengthen the young physicians' sense of innovation and scientific research ability.

Objective To study the safety,feasibility and efficacy of thoracoscopic hepatectomy for liver carcinoma. Methods Thoracoscopic hepatectomy was performed in 3 cases with single liver neoplasm from 2007 to 2011,including hepatocellular carcinoma ( HCC ) in one case and metastatic liver cancer in 2 cases.By preoperative imaging the tumor was located accurately to simulate the port position in operation.Patients were placed in a left lateral decubitus position,and 3 ports were inserted into the chest wall surrounding the tumor. Through the use of intra-operative thoracoscopic uhrasonography (IOTU),the diaphragm just above the tumor was opened.IOTU was performed on the liver surface and the resection line was marked.Throughout the course of parenchymal transection,IOTU was performed repeatedly to guide the resection line,and ensure the complete removal of the tumor.After meticulous hemostasis of the resection surface,the diaphragm was closed. A thoracic drain was left. Results Thoracoscopic hepatectomy succeeded in all 3 cases,the median total operating time was 150 min (110 -210 min),and the medianblood loss was 297 ml (130 -600 ml). Patients recovered quickly and had no major post-operative complications.During 9 to 42 months' follow-up,one patients died of other cause,no relapse of the diseases was found. Conclusions Thoracoscopic hepatectomy is a safe and feasible operation in selected patients and has advantages in post-operative morbidity and in hospital time.

Objective: To study the expression and localization of apoptosis-related protein TFAR19 in TF-1 cells undergoing apoptosis. Methods: Using monoclonal antibody against TFAR19, the expression level and cell localization of TFAR19 were examined by fluorescence microscope, confocal laser scan microscope(CLSM) and flow cytometry. Simultaneously, we also analyzed the relationship of TFAR19 protein with phosphatidylserine (PS) externalization and cell nuclear DNA fragmentation. Results: The level of TFAR19 proteins expressed in TF-1 cells treated with GM-CSF withdrawal was significantly increased compared with normal TF-1 cells, then translocated rapidly from cytoplasm to the nucleus of cells. Appearance of TFAR19 in the nucleus of apoptotic cells preceded the detection of PS externalization and DNA fragmentation. Conclusion: Nuclear translocation of TFAR19 protein is one of the earliest events of cell apoptotic process. These data provided a new clue to further approach to the biological function of TFAR19 and study of cell apoptosis.

AIM: To clarify the role of new apoptosis-related gene, TF-1 cell apoptosis-related gene 19(TFAR19), in the pathogenesis of systemic lupus erythematosis (SLE) and the relationship between TFAR19 and SLE. METHODS: DNA Ladder detection, Western blotting, immunological fluorescence method, ELISA and so on were used to test if ultraviolet B(UVB) could induce HaCaT cell apoptosis and TFAR19 expression. RESULTS: HaCaT cell apoptosis could be detected after 24 hours of 30 mj/cm 2 UVB irradiation. Also, we found that in active SLE patients, the TFAR19 antibody was increased, but not significant compared to the normal control. CONCLUSION: TFAR 19 is involved in the process of UVB induced ketatinocyte line HaCaT apoptosis and SLE pathogenesis.
