Objective To evaluate the efficacy and safety of acupuncture as adjuvant treatment in the management of diabetic foot (DF).Methods We searched MEDLINE,Embase,CENTRAL,SinoMed,VIP,CNKI and WANFANG database.We also searched the bibliographies of retrieved articles and correlated proceedings and collected the literatures of DF of clinically randomized or quasi-randomized control trials of acupuncture as adjuvant treatment.After the data was extracted independently by 2 reviewers,we performed meta-analysis by using RevMan 5.1 software.Results Seven studies included 626 patients who met the inclusion criteria,and all employed clinical effects as evaluation indicator.Meta-analysis showed that acupuncture as adjuvant treatment could obviously improve the total effectiveness rate(RR =1.29,95％ CI:1.20,1.38,P ＜ 0.00001)and the recovery rate(RR =1.92,95％ CI:1.60,2.30,P ＜ 0.00001 ).No adverse reactions occured.Conclusions The limited current evidence shows that acupuncture as adjuvant treatment is safe and effective in the treatment of DF.Due to the poor quality of original studies,a prudent choice is suggested.Further studies with high quality and large samples according to CONSORT are also warrant.

Objective To explore the effect of follow-up nursing intervention on preventing dental plaque during oral fixed orthodontic appliance.Methods One hundred and twenty orthodontic patients receiving oral fixed orthodontic treatment were randomly divided into control and experiment groups equally according to visit time.The control group received conventional nursing during the process and follow-up nursing intervention during the process.The two groups were compared in terms of dental plaques before orthodontic, 3 and 6 months after the orthodontic treatment.Results Before the treatment, there was no significant differences in the dental plaques between them(P>0.05), but the indices of dental plagues in the experimental group were significantly lower than those of the control group 3 and 6 months after the orthodontic appliance(P<0.001).Conclusion Follow-up nursing care during orthodontic appliance are more effective for keeping oral hygiene.

Objective To explore the relationship between gene MTDH expression and its role in promo-ting gastric carcinoma metastasis .Methods We collected clinical specimens and cultured gastric carcinoma cell lines.By Western blotting and Real -time PCR methods,protein and mRNA levels in tissues and MTDH relation-ship with EMT were detected .Results There was 86%of patients who expressed MTDH positively and 13%of normal gastric mucosa was positive expression .The results showed that the expressive level of MTDH gene in gas-tric carcinoma was higher than in the normal tissues .The expression of MTDH was correlated with TNM stage、mi-crovascular invasion、recurrence and metastasis .The expressive level of MTDH was correlated with two epithelial mesenchymal transition markers ( E-cadherin and N-cadherin ) .Conclusion MTDH may promote gastric car-cinoma metastasis through the induction of EMT process and may be a candidate biomarker for therapeutic target .

Objective To understand the current situation and trend on the relations between erectile dysfunction (ED) and cardiovascular disease (CVD) through analyzing the epidemiologic research data.Methods We conducted a literature search on the Scopus for potentially relevant epidemiologic studies on ED and CVD published from 1957 to October,28,2016.Age of the article,types,regions,citation,and co-authorship of the documents were recorded.Results A total number of 412 pieces of literature were published in the past six decades,with original articles the most common types of ED and CVD.ED and CVD associated epidemiologic topics had an annual increase in number,and remained stable in the past decade,with occident countries as the United States and Italy taking the lead in this area.Clinical and epidemiological studies were the hottest areas,with most authors sharing a co-authorship.Conclusion Our results suggested that inter-disciplinary cooperation with emphasize on clinical application were the effective starting points for ED and CVD associated epidemiologic studies.

Objective: To explore the influence of different cement spaces on the marginal adaptation of CAD/CAM zirconia inlay. Methods: 30 teeth extracted for orthodontic purpose were selected and divided into 3 groups (Group A 10 μm, Group B 30 μm, Group C 50 μm). The marginal spaces of inlays were recorded by the light-body Silicone impression material, and measured by microscope. The data were analyzed by SPSS 13.0. Results : All the inlays fitted very well and all the marginal spaces were less than 120 μm. The shoulder of Group A was statistically lower than Group B and Group C (P < 0.05). The axial surface of Group B was statistically lower than Group C (P < 0.05). Conclusions CEREC zirconia inlay is satisfactory when the cement space is between 10-50 μm.

Objective:To summarize the clinical characteristics and prognosis of acute hyperextension spinal cord injury (SCI) in children, and to provide some recommendations for the treatment and prevention of this disease.Methods:Reviewed the data of children of SCI after sustained or repeated hyperextension of the spine at Wuhan Union Hospital and Wuhan Children's Hospital from September 2010 to September 2020. According to the American Spinal Injury Association impairment scale (AIS grade), the patients were divided into complete SCI group and incomplete SCI group. The age, symptoms and evolution after injury, neurological level of injury, imaging data, laboratory examination data, prognosis and complications of the two groups were analyzed. Retrospectively summarize the characteristics of this type of injury.Results:Forty-four cases of acute hyperextension SCI in children were included. Their age ranged from 3 to 10 years old, 95% of them were under 8 years old and 95% of them were female. There was no significant difference in age at injury and time of dance training between children with complete SCI and incomplete SCI. Back and leg pain, lower limb weakness or paresthesia, and rapidly progress to complete or incomplete SCI in a short period were typical symptoms. All blood test results anddiagnostic analysis of cerebrospinal fluid were unremarkable or negative. There was no fracture or dislocation in the whole spine. Magnetic resonance imaging showed a longitudinally extended intramedullary high-intensity signal in the thoracolumbar spinal cord. Complete SCI accounted for 60% of all cases, and the prognosis was poor with spinal cord atrophy and various complications.Conclusion:Children younger than 10 years old after sustained or repeated hyperextension of the spine may suffer acute hyperextension SCI. Children with complete SCI have poor prognosis and serious complications. Therefore, prevention of this type of injury is the best strategy.

Meta-analysis used for genetic association studies became popular among researchers,with the amount of published papers increased rapidly.In this paper,we will focus on the introduction on the selection of genetic models.Traditionally,methods used for Meta-analysis on genetic association studies was to calculate the statistics based on available genetic models which not only increasing the probability of false-positives but also making the interpretation of results more difficult.Hence,a critical step in the Meta-analysis of genetic association studies was to choose the appropriate inheritance model.The aim of this paper was to introduce the theory of Bayesian analysis regarding the genetic model-free approach,in performing the Meta-analysis for studies related to genetic associations.

Objective: To evaluate the relationship between-590C/T polymorphisms of interleukin-4 gene and periodontitis by meta-analysis. Methods: Databases including PubMed, EMbase, Web of Science, CBM, CNKI, Wanfang and VIP, were searched from their establishment to December 31, 2016. Only case-control studies on the association between -590C/ T polymorphisms of interleukin-4 gene and periodontitis were selected, and the references of those selected studies were searched by hand. Assessment and data extraction were conducted by 2 reviewers independently, and the meta-analysis was performed with the R 3.3.1 software. Results : The meta-analysis showed that there was no association between the IL-4-590C/T polymorphism and periodontitis susceptibility (T vs C: OR=1.19, 95%CI=0.81~1.76, P =0.37). Subgroup analysis showed that the IL-4 -590 TT was associated with periodontitis in Caucasians (TT vs CT: OR=1.75, 95%CI=1.10 ~ 2.78, P = 0.02), but no significant association in Asians (P =0.63). Meanwhile, IL-4 gene polymorphisms were not significantly associated with the susceptibility of chronic periodontitis (CP) or aggressive periodontitis (AgP) ( e. g. T vs C, CP: P=0.45; AgP: P =0.45). Conclusion Based on current evidence, the polymorphisms of IL-4-590C/T are associated with the increased risk of periodontitis in Caucasians.

The purpose of this study was to investigate the NOAEL of the nickel ion and provide with basic data for the biological evaluation of those medical devices containing nickel. Five groups SD rats were repeatedly exposed during 14 d respectively to nickel at first stage doses of 4.9, 3.7, 2.5 mg/(kg.d), and the second stage doses of 1.2, 0.25 mg/(kg.d) by the intravenous route. The results showed that the NOAEL of nickel ion is 0.25 mg/(kg.d) for SD rats, and the result was verified by subchronic systemic toxicity test of nickel alloy. The threshold of toxicological concern (TTC) of nickel is 150 μg/d (based on application of 100-fold uncertainty factor and a body weight of 60 kg)deduced by these data.

BACKGROUNDThe objective of this study was to analyze the trend in the publication of systematic reviews on hip fractures through a bibliometric approach.

METHODSLiterature including systematic reviews or meta-analyses on hip fractures was searched from the ISI Web of Science citation database. The search results were analyzed in terms of geographical authorship and frequency of citation by country, institution, author, and periodical distribution.

RESULTSA total of 654 published systematic reviews from 1995 to 2013 in 48 countries or regions were retrieved. The United States (171) was the predominant country in terms of the number of total publications, followed by the United Kingdom (149), Canada (120), Australia (76), and China (54). The number of systematic reviews significantly increased during the last 6 years, especially in China. The production ranking changed in 2012, at which time the United States and China were the leaders in the yearly production of systematic reviews on hip fractures. The amount of literature (27 publications) from China contributed almost one-quarter of the total literature (109 publications) in 2012. However, the average number of citations of each article from China was still low (6.70), while the highest number of citations of each article was from Sweden (193.36). The references were published in 239 different journals, with 15 journals contributing to 41.3% of the systematic reviews on hip fractures. The two journals that contributed the most were Osteoporosis International (10.6%) and the Cochrane Database of Systematic Reviews (7.6%). The predominant institution in terms of the number of publications was McMaster University (36) in Canada.

CONCLUSIONSThe best evidence in the field of hip fractures has attracted increasing attention. Systematic reviews on hip fractures from China have been increasingly more frequent during the past 6 years, particularly in 2012.
