Next generation sequencing technologies,providing high speed and throughput that contribute greatly to DNA sequencing,have many applications in clinical virology,including identification of novel or unsuspected viruses,evaluation of human viromes,investigation of viral genetic diversity and evolution,monitoring of antiviral drug resistance,and analysis of virus-host interaction.Meanwhile,due to the complexity in bioinformatics data processing and lack of quality management standards,further efforts and explorations need to be put in the application and quality management of NGS in clinical laboratory.

ObjectiveTo analyze the results of implementing the tutorial system for medical interns, and to put forward some suggestions. MethodsThe medical interns and the doetors selected as tutors were asked to do questionnaires to study the tutorial system's feasibility and effectiveness. Simultaneously, we adopted the Objective Structured Clinical Examination ( OSCE ) to assess its process and resuits. Results74.3％ of the students and 75.5％ of the doctors think that they need the tutorial system,73.2％of the students think that this system can train better clinical skills,67.9％ of the doetors think that they can review the knowledge learned through teaching. Implemented after one year, students' OSCE scores are improved. ConclusionTutorial system for medical interns has achieved preliminary success, and the preparatory work and related-system building need to be further improved.

Cocaine-and amphetamine-regulated transcript (CART), an endogenous neuropeptide, is widely distributed in human organs and tissues, such as brain, gastrointestinal tract and pancreas. It has a variety of important physiological functions, including eating and obesity, stress, mental anxiety, drug addition, and endocrine regulation. Previous studies have suggested that CART is widely distributed in the central nervous system, and it involves in the regulation of a variety of physiological processes and has some central protective effects. It is a potential neuroprotective agent. This article reviews the recent progress in research on the neuroprotective effect of CART on stroke and neurodegenerative disease and its mechanisms, as well as its therapeutic effect in central nervous system diseases.

Objective To evaluate the long-term outcome ofautologous epidermal grafting in vitiligo and its correlated factors. Methods A 1-5 year follow-up of 310 patients with vitiligo, who had been treated by autologous epidermal grafting, was carried out by questionnaires, phone interview, and clinical revisit. The relevance was estimated between the efficacy of the treatment and several factors, including the time length from the grafting to the follow up, patients' age and gender, location of lesions treated, Koebner phe-nomenon on the donor sites, and the combination therapy with narrow band-ultraviolet B (NB-UVB). Results Of the 310 patients, 161 were males and 149 females with an average age of 26.69±11.76 years; 98 had localized vitiligo, 123 segmental vitiligo, 62 scattered vitiligo, 27 generalized vitiligo. Totally, 24 recipient areas with 1266 sheets were evaluated. Among these sheets, 815 (64.38%) achieved complete repigmenta- tion, 167 obvious repigmentation, 117 some repigmentation, 167 no repigmentation, with a curative rate of 64.38% and total effective rate of 86.81%. Hyperpigmentation occurred in the recipient area of 76 (24.52%) patients, and donor area of 34 patients (10.97%), and hypopigmentation developed in the recipient area of 66 patients (21.29%). Relapse developed in the recipient areas of 30 patients, and new lesions in 12 patients (3.871%). Koebner phenomenon was noticed in the donor sites of 25 (8.064%) patients. The efficacy of autologous epidermal grafting was stable within two years after the therapy, but reduced with the time. Increased efficacy was observed in those sites with little mobililty and large fixity. For example, the best effi- cacy was observed in the legs and arms, followed by feet and hands, chest and back, face and neck, finally by waist and abdomen (P<0.01). NB-UVB exposure could improve the repigmentation. Koebner phe- nomenon in donor sites was associated with a reduced efficacy of epidermal grafting (P<0.05). Gender and age seemed unrelated to the efficacy. Conclusions Autologous epidermal grafting has a good long-term efficacy for the treatment of vitiligo, and transplanted location may be the most important factor affecting the efficacy.

Objective To study the current situation of diagnosis and treatment of rudimentary uterine horn pregnancy through 4-cases report. Methods We made a clinical study of 4 cases of rudimentary uterine horn pregnancy admitted to our hospital between 1995 and 2005. Results Three patients had been undergone artificial abortion before they were admitted to our hospital. All the patients were asymptomatic. Ultrasonography was made in 3 cases. Two cases were diagnosed as rudimentary uterine horn pregnancy. Three patients were cured with surgery. Conclusions Rudimentary uterine horn pregnancy is rare and with atypical clinical manifestation in the first trimester. Although diagnosis before surgery is difficult, ultrasonography and MRI make a great role. Surgery is the most important therapeutic method.

An animal model of hemorrhagic shock is widely applied .It is an important platform to clarify the pathogenic mechanism, develop hemostasis materials , test first aid equipments and filter resuscitation medications .This paper summa-rizes the commonly used animal models of hemorrhagic shock at home and abroad , focusing on animal selection , model cre-ation, influencing factors , and fields of application in order to provide useful reference for model selection and application by medical practitioners and researchers .

[Objective]The paper was designed to introduce the Professor YE Jin's personal clinical experience which can provide an effective means for other pediatrician.[Method]By introducing the Professor YE Jin's personal clinical experience,we summarize the effective therapies about the infantile recurrent abdominal pain(RAP). [Result]According to the Professor YE Jin, the pathomechanism of RAP includes mainly cold stagnation, the indigestion, parasite and Qi stagnancy. RAP caused bycoldcan be treated from warming the middle-energizer and fending off the cold,RAP resulting from retention of food can be cured by removing the retention and invigorating the stomach, RAP incurred by ascaris can be cured by relieving ascariasis,expelling parasite and purgation simultaneously,and RAP resulting from Qi stagnation can be cured by soothing liver, regulating qi activity, rather than relieving pain merely. Based on the above-mentioned theory,she tends to use Liquorice and prefers Paeonia a lot in curing the disease, that is always effective in clinic as a result.The recurrence rate is also lower.One case was provided for verification.[Conclusion]Professor YE Jin thinks that warming the middle-energizer and fending off the cold, removing the retention and invigorating the stomach, the RAP can be improved the curative effect,and that can provide another idea for other clinicians.

Inhibition of tumor neovascularization (angiogenesis) has become one of the novel therapeutic strategies for tumor, and natural inhibitor of angiogenesis has been highlighted in this field. Thrombospondin-1 (TSP-1), as an important extracellular matrix component which can influence endothelial cell adhesion, migration, and proliferation, is reported to be a potent inhibitor of angiogenesis in vivo. It will be valuable to use its active peptides or small fragments from TSP-1 in antiangiogenesis therapy.

OBJECTIVE:To investigate the methods of calculating pediatric dose of medication.METHODS:The validity of several methods of calculating pediatric dose of medication was evaluated by statistical methods and demonstration analysis,and the expression of the pediatric dosage of administration in drug instruction was discussed.RESULTS&CONCLUSION:There exist improper medical manipulation in the rational use of medicines in pediatrics,uniform criterion and calculation are lack for measuring age groups in pediatrics,aseries of integrated and uniform criteria to determine the safe dosage for child are needed.
