Objective: To explore the object relation in the college students with borderline personality disorder(BPD) by thematic appearance test (TAT). Methods: The result of the social cognitive and object relation scale (SCORS) of BPD students was compared with that of the non-BPD students. Results: The BPD students got significantly lower scores in complexity of representations of people, affect-tone of relationship paradigms, and understanding of social causality. But there was no significant difference in the capacity for emotional investment in relationships and moral standards. Conclusion: The object relation of BPD students is different from that of the non-BPD students. The non-BPD students develop better in complexity of representations of people, affect -tone of relationship paradigms, and understanding of social causality.

The overuse of injection exists more than 20 years since economic reform in China. It is a persistent problem and seems becoming a new challenge in the new health reform period. This study was designed to assess the effect of national essential medicines policy (NEMP) on injection use at primary health facilities in China by investigating their prescription information. Questionnaires were designed and disseminated to collect empirical data on injection use at 120 primary health facilities in 6 provinces from January to September in 2010 and 2011. The injection use was measured as the indicator as the percentage of prescriptions with one or more injections. The results showed that the percentage of prescriptions with one or more injections was decreased from 38.91% to 36.82% (χ (2)=11.158, P=0.001) in the all survey areas during the NEMP reform. The difference in level of the injection use in 2011 was significant among the eastern, central and western regions (χ (2)=223.584, P=0.000); level of the injection use in western region was the lowest (27.73%), while that in the central region was the highest (43.10%). The level of the injection use in 2011 among different provinces was also of great difference (26.00%-58.25%, range: 32.25%). The level of the injection use in 2011 was still much higher than the standard suggested by WHO for developing countries (13.4%-24.1%). It was concluded that NEMP has improved injection use in China, but the injection abuse situation remains serious, indicating that one of the priorities to the next stage of NEMP is to promote the rational use of drugs, especially the injection use.

Combination chemotherapy and nanoparticle drug delivery are two promising strategies in cancer treatment. The use of multiple therapeutic agents in combination provides synergistic effects among different drugs against cancer cells and suppresses drug resistance through distinct mechanisms of action.Nanocarriers can improve anti-tumor effects of drugs and reduce systemic toxicity through delivering drugs into the tumor tissue specially. Recently, many studies are aiming to encapsulate multiple agents into nanocarriers to optimize the anti-tumor effects. In the present review, the recent advances of nanoparticle platforms applied with co-delivering two or more drugs were summarized and the various combination strategies based on nanoparticles in oncology were discussed.

Objective To evaluate the in vitro antibacterial activity of fusidic acid against P.acnes.Methods Fifty strains of P.acnes were clinically isolated from Huashan Hospital,Fudan University from March to September 2013.The minimum inhibitory concentrations (MICs) of several antibacterial agents including fusidic acid against these P.aches isolates were determined by using the agar dilution method according to the recommendations of Clinical and Laboratory Standards Institute (CLSI).Data were analyzed using the WHONET 5.4 software.Results Among the 50 P.acnes isolates,90％ were sensitive to fusidic acid,90％ to moxifloxacin,54％ to clindamycin,46％ to erythromycin,but 100％ were resistant to metronidazole.The minimum concentration required to inhibit the growth of 50％ organisms (MIC50) and 90％ organisms (MIC90) were 0.5 and 1.0 mg/L respectively for fusidic acid,whereas clindamycin and erythromycin both showed higher MIC90 values (＞ 128 mg/L).At the concentration of 128 mg/L,clindamycin inhibited the growth of 70％ of the P.acnes isolates,and erythromycin inhibited the growth of 48％ of them,while the growth of all the isolates was inhibited by fusidic acid at 2 mg/L.Conclusion Fusidic acid exhibits excellent antibacterial activity against clinical isolates of P.acnes in vitro.

BACKGROUND:Extensive studies have shown that transcutaneous electrical nerve stimulation (TENS) plays a positive role in relieving the pain caused by a variety of diseases. However, its exact effect to manage pain in patients with knee osteoarthritis is stil controversial. TENS is classified into h-TENS and l-TENS, but currently its respective role in relieving the pain caused by knee osteoarthritis is not clear yet. OBJECTIVE: To compare the efficacy of h-TENS and l-TENS on pain relieving among patients with knee osteoarthritis. METHODS: A computer-based search was performed on PubMed, Embase and Cochrane database for randomized controled trials on TENS for the treatment of knee pain in patients with knee osteoarthritis which were reported before February 2014. Methodology quality of the trials was criticaly assessed and relative data were extracted. These studies were selected independently by two reviewers according to the inclusion and exclusion criteria. Meta-analysis was performed using Revman5.2 software. RESULTS AND CONCLUSION:A total of 10 randomized controled trials involving 519 cases were included. The results of meta-analysis showed that the h-TENS group had significant effects on pain relief in knee osteoarthritis patients in comparison to the control group [MD=-0.56, 95%CI(-0.98,-0.15),P=0.008]; the l-TENS group had no significant effect on pain relief in knee osteoarthritis patients in comparison to the control group [MD=-0.13, 95%CI(-1.63, 1.38),P=0.87]; the h-TENS group had significant effect on pain relief in knee osteoarthritis patients in comparison to the l-TENS group [MD=-0.85, 95%CI(-1.32, -0.37), P=0.000 5]. These findings indicate that h-TENS performs something positive to reduce pain in knee osteoarthritis patients that l-TENS cannot do. Owing to the limitations of this study, further work is needed to determine the role of TENS in pain management among patients with knee osteoarthritis.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

OBJECTIVETo study the therapeutic efficacy of manipulative reduction and percutaneous pin fixation for the treatment of severely displaced distal tibial fractures in children.

METHODSFrom May 2009 to December 2012,56 children with severely displaced distal tibial fractures were analyzed, who had been treated with manipulative reduction and percutaneous pin fixation. Preoperative fractures were confirmed as severely displaced fractures by X-ray apparatus. There were 33 boys and 23 girls,ranging in age from 3 to 14 years, with an average of 10.1 years. All the fractures were closed without vascular or nerve injuries. According to the bone fracture type, under C-arm fluoroscopy, functional reduction was achieved by manipulative reduction. The fractures were fixed with percutaneous pins. Postoperative X-ray confirmed the functional reduction. Follow-up indexes were recorded: intra-operative and postoperative complications,postoperative radiographic examination, lower extremity length and range of ankle motion. Ankle score system of Teeny was used to evaluate ankle function.

RESULTSAll the patients were followed up, and the duration ranged from 3 to 46 months, with an average duration of 19.4 months. According to the Teeny score standard, 35 patients got an excellent result, 7 good and 3 fair. Pin track reaction was found in 4 cases. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. All the patients could participate in the normal physical activities, having a normal range of motion and excellent strength of the ankle joint.

CONCLUSIONThe method of manipulative reduction and percutaneous pin fixation is a safe and convenient treatment for severely displaced distal tibial fractures in children. It has several advantages as follow: micro-trauma, tiny tissue damage, firm fixation, and the patients can exercise the function of ankle early, suggesting that it is an effective treatment method.
