Objective To assess the quality of literature on randomized or semirandomized clinical controlled trials of fire needling treatment for rheumatoid arthritis.Method Acomputer search assisted by a manual search was conducted of CBM (1979—2015), CNKI (1979—2015), VIP (1989—2015),Wanfang digital periodical group(1998—2015), PubMed (1966—2015), EMbase (1980—2015) and Cochrane Library (Issue4, 2015).Randomizedor semir and omized clinical controlled trials were included.Two reviewers extracted data independently and checked them each other.The methodological quality of research design, diagnostic and inclusion/exclusion criteria, intervening measures for fire needling/control group,efficacy evaluation criteriaand observation time points, and adverse reaction reporting were assessed according toCochrane Reviewers' Handbook 4.2.8.Ameta-analysis was made of homogeneity studies.The GRADE approach ratedsystem outcomes.ResultA total of sevenr and omized controlled trialswere included.Four included studies made a comparison between fire needling andmedication (analgesic+ antirheumatic) groups andthere was no statistically significant difference in the efficacy rate [RR=1.22, 95%CI(0.97, 1.52)].GRADE ratingwas very low.Internationally accepted diagnostic criteria and general evaluation methodswere still not used universally.Conclusion The current clinical reports show that fire needling treatment has some effect on rheumatoid arthritis, but it still needs related evidence support.

Great progress has been made in tissue engineering cornea construction (i.c.constructing human corneal equivalence by using tissue engineering technique) during the past 20 years.However,a kind of tissue engineering cornea which can be applied to corneal transplantation as human cornea equivalent is yet to be availablc.Scaffold is an indispensable part of tissue engineering cornea.Searching for some kinds of scaffolds with good biocompability,some extent of biodegradation and euough biomechanics property are the issue needing to be resolved immediately in the tissue engineering cornea filed.This article reviewed the development of tissue engineering cornea scaffolds,represented the merits and defects of different scaffolds in order to optimize the project of choosing scaffolds and furthermore lay the foundation for constructing a kind of tissue engineering cornea which may be applied to corneal transplantation as human cornea equivalent in the future.

Objective To study on postpartum obsessive compulsive disorder at home and abroad,and to provide new idea of diagnosis,evaluation and treatment on postpartum obsessive compulsive disorder.Method A search using Medline,Embase,EBSCO,Cochrane Library,Web of Science (ISI),Pubmed databases and Google Scholar was carried out using the key words:obsessive compulsive disorder (and derivatives),perinatal,pregnancy,postnatal,postpartum,mothers (and derivatives),anxiety disorders and subtypes. These articles and their references were reviewed.Results Twenty-seven papers were incorporated,but no Chinese paper.The life prevalence of postpartum OCD was 2.3％-11.0％.The most common obsessions were aggressive,contamination and miscellaneous,and compulsion for washing/cleaning and checking.Cognitive behavioural therapy and SSRIs have been suggested as a fist-line treatment of postpartum OCD.Conclusion OCD is more prevalent in the postpartum period.The evidence that OCD in the postpartum period presents a distinctive clinical picture with specific symptomatology and course is more compelling.Collaborative,international,prospective studies that take into account the methodological and definitional issues raised in this review are necessary to provide clarification.

ObjectiveTo investigate the effect of weight self-management in reproductive-aged obese women with polycystic ovary syndrome(PCOS).Methods A total of 56 reproductive-aged obese women with PCOS were divided into two groups with the control group administered medicine to reduce the lipid,blood glucose and metformin and the experiment group managed with weight self-management in addition of the medicine treatment as in the control group.All of them were treated for six months.The number of women with oligomenorrhea,body mass index(BMI),waist-hip ratio(WHR),serum total cholesterol(TC),triglyceride(TG),fasting blood glucose(FBG), fasting insulin(FINS),homeostasis model assessment(HOMA)were measured before and after intervention for comparisons.Result The number of women with oligomenorrhea together with the levels of TC,TG,FBG,FINS and HOMA were significantly reduced in the two groups(allP<0.05),and the number of women with oligomenorrhea and the levels of BMI,TC and HOMA were decreased more than those in the control group(allP<0.05).Conclusion The weight self-management on the basis of drug therapy for reproductive-aged obese women with PCOS can significantly reduce the levels of BMI,WHR,TC,TG,FBG,FINS and HOMA,enhance the effect of drug therapy, reduce the incidence of oligomenorrhea and improve the metabolic disorders.

BACKGROUND:Evaluation of the newly formed bone at the distraction site by the imaging technologies is the cornerstone for terminating the limb lengthening successfuly.In the early stages of the distraction, the X-ray cannot detect any evidence of new bone formation within the distraction sites, whereas ultrasound can acquire wealth information about new bone and surrounding soft tissues. OBJECTIVE: To explore the application value of Doppler ultrasound in the evaluation of limb lengthening in order to promote its clinical application. METHODS: A computer-based search was performed on the CNKI database and PubMed database for articles related to ultrasound in the evaluation of limb lengthening published from January 1989to October 2014. The keywords of distraction osteogenesis, ultrasonography, external fixation, fracture healing in English and Chinese were used to search the articles by title and abstract. Finaly, a total of 24 articles were included to review. RESULTS AND CONCLUSION: Ultrasound is an effective method to evaluate the limb lengthening in early stage. It can not only detect the formation and maturation of the new calus, but also can evaluate the forming speed and the quality of the new cals. Moreover, ultrasound can be used to evaluate the situation of the soft tissue near the distraction site. Complications associated with the limb lengthening can be observed timely by the ultrasound. Ultrasound is of great significance in the evaluation of distraction osteogenesis.

Methods 30 cases of molars pulpitis and 20 cases of premolars pulpitis or periapical periodontitis were equally divided into two groups .The group A(30 cases) used the ProTaper rotary nickel-titanium files in root canal preparation and the group B (30 cases) adopted the common K files modified step-back technique for root canal preparation .The influence of the root preparation by 2 sets of apparatus on the effect of root canal filling ,and the several aspects of the root canal filling time ,the matching degree of main root canal file and master gutta-percha ,proper filling rate ,postoperative reaction of root canal filling were compared for conducting the e-valuation .Results In the mean root canal filling time of the group A ,average premolar time was 4 min 25 s and molar was 1 min 30 s ,however in the group B ,average premolar was 5 min 30 s and molar was 11 min 41 s ,the time in the group A was greatly short-ened with statistical difference(P<0 .05);the matching degree of main root canal file and master gutta-percha in the group A was 86 .37% for premolar and 88 .89% for molar ,however in the B group ,which was 62 .50% for premolar and 26 .67% for molar ,the matching degree in the group A was greatly improved with statistical difference between them (P<0 .05);the proper filling rate of upper premolar from the X-ray film was 72 .73% in the group A and 70 .83% in the group B ,while which of molar was 80 .0% in the group A and 77 .78% in the group B ,here was no statistical difference between them (P>0 .05);the postoperative pain reaction of root canal filling in both groups were very low and weak without statistical difference .Conclusion The ProTaper rotary nickel-titanium files root preparation can accelerate the root canal filling speed ,improve the matching degree of main root canal files and master gutta-percha and simplify the root-filling therapy procedure .

The clinician training system in Japan is different from that in China as their medical students are allowed to take medical doctor examination immediately following their graduation.But they must undergo at least two years of training in basic clinical knowledge and skills prior to taking any clinical practice.This training system is inspirational for us as follows:China should include standardized training of residents into the law of medical practitioners,and medical graduates must take two years of knowledge training in full medicine before they are qualified for clinical practice.On top of this training,they need to undergo at least three years of specialized doctor training,making them competent clinicians with comprehensive knowledge coverage and outstanding skills in specific areas following such staged training.

For medical insurance systems, medical expense examination is a key measure to keep medical expenses under control. In 1948, Japan established an examination authority of legal person status to operate the medical expense examination. Based on years of modifications and improvement in the organizational system and operation mechanism, the system is running smoothly by now. Authors of this paper made a detailed introduction to the specific operations of such a system, and to China's local features as well. On such basis, the study proposed to build in China a third-party medical expense examination institution as a legal entity, and practice the reexamination system and information disclosure system, in an effort to safeguard legitimate rights of insurance organizations and medical institutions.

Interleukin-24 (IL-24) is a novel cancer suppressor cytokine. It can suppress cancer cell growth, induce cancer cell apoptosis, inhibit angiogenesis, stimulate the PBMC secretion of cytokines, and enhance the antitumor activity of radiotherapy, chemotherapy and targeting gene-virotherapy. It is reasonable to suggest that IL-24 may be a powerful and effective protocol for combinatorial cancer treatment in the clinic.
