1.Evaluating the effect of embelin combined with paclitaxel on inhibiting A549 lung cancer cell proliferation and tumor growing in tumor-bearing nude mice growing
Chinese Journal of Biochemical Pharmaceutics 2014;(2):7-9
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.

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.

Neurodevelopmental disorders are diseases affecting language,sports,intelligence and social adaptability,and through appropriate early intervention,part of the affected children can recover to the same or similar level as normal children,so it is of vital importance to provide accurate early identification and comprehensive intervention for the affected children.Now the gene technology is applied widely,especially the next-generation sequencing is characterized by high throughput,low cost and fast sequencing,which has made great progress in assisting the diagnosis of children with unexplained neurodevelopmental disorders.Therefore,genetic diagnosis can be used to understand the prognosis of children and to provide genetic counseling for their parents,which is conductive to reducing their incidence and early intervention.

Objective To observe the clinical effects on prevention of alveolar bone absorption by site preservation after tooth extraction due to periodontitis.Methods The experimental group consisted of 40 patients with 45 extracted teeth due to periodontitis.The fresh sockets were immediately grafted and filled with Bio-oss collagen and Bio-Gide after minimally invasive tooth extraction,while 40 teeth of control group were only treated with cotton balls bitten tightly over the socket for half an hour.Two groups were observed for changes in alveolar bone density by X-ray and cone beam CT (CBCT)after 6 months.Results There were the wound healing and no infection in extraction site of all patients with or without site preservation operation.The gingiva of extraction site was pink and tough in all groups.The alveolar bone loss in regular extraction patients significantly increased in horizontal and vertical aspects by X-ray and CBCT,while site preservation improved the alveolar bone defects (P<0.05).After site preservation for 6 months,CBCT analysis showed that the density of new alveolar bone markedly enhanced compared with regular extraction group.Conclusion The technique of site preservation after tooth extraction due to periodontitis is a method which can prevent and reduce disuse atrophy absorption of the alveolar ridge so that the height and width of the alveolar bone can meet aesthetic requirements.
