Objective To detect TRAF1 gene single nucleotide polymorphism in Han population ,and analyze its association with increased risk of rheumatoid arthritis (RA) in Han people. Methods The study group was comprised with 100 healthy Han subjects and 100 Han RA patients. Six SNPs was detected by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOFMS), and the result was analyzed by Haploview software. Fisher's exact test and χ2 test were used for statistical analysis.Results The rs4836834 A/A, A/T, T/T allele frequencies of RA group were 22.22%, 49.49%, 28.28% respectively. The rs4836834 A/A, A/T, T/T allele frequencies of healthy control group were 28.57%, 30.61%,40.82% respectively. There was significant difference (P<0.05) of rs4836834 between Hah patients with RA and healthy controls. For other five sites, including rs10818488, which had been reported to be associated with increased risk of Caucasians RA patients, there was no significant difference (P>0.05) between RA group and the control group. The linkage disequilibrium and haplotype frequency analysis results showed that there was strong linkage disequilibrium between rs7021049 and rs7021880, rs7021049 and rs4836834, rs7021880 and rs4836834, but there was no significant difference between RA group and the control group in the haplo-type frequencies of the three classes of linkage disequilibrium. Conclusion TRAF1 gene may be a susceptible gene associated with Han RA people, but its single nucleotide polymorphisms and performance may be different between Caucasians and Han people.

Hand, foot, and mouth disease (HFMD) is a viral infectious disease regarded to be a public-health problem worldwide. Since the 1990s, HFMD began to spread in the Asia-Pacific region (especially in South-East Asia). HFMD outbreaks have occurred in mainland China frequently since 2008, and the morbidity and mortality of HFMD has continued to increase in recent years. In mainland China, enterovirus A serotype enterovirus A71 (EV-A71) and coxsackievirus A16 (CVA16) have been the major pathogens of HFMD during these years. However, the etiological spectrum of HFMD changes with time. This review focuses mainly on the etiological spectrum of HFMD and changes in epidemic patterns in mainland China.

Joint prosthesis is one of the most successful procedures in orthopaedic surgery and has considerably improved the quality of life for patients affected by terminal joint disease. However,a number of joint prosthesis ultimately failed because of aseptic loosening. There have been major advances in the understanding of aseptic loosening. The RANKL-RANK-OPG-NF-?B system has been shown to play a fundamental role in aseptic loosening. We review how the RANKL-RANK-OPG-NF-?B system regulates aseptic loosening and aseptic loosening drug intervention.

Objective To investigate the clinical effect of laparoscope microwave ablation therapy for liver cancer.Methods Twenty-four special sites (at least 1 lesion close to diaphragmatic muscle,gallbladder,stomach,colon and big lacuna exterior and interior of liver) of primary liver cancer patients (32 nodes) were selected,and the patients were treated with laparoscope microwave ablation therapy.The rate of complete remission after treatment,the level of alpha-fetoprotein (AFP) before and after treatment,postoperative complication and follow-up condition were observed.Results All the patients successfully completed the operation.The rate of complete remission after treatment was 87.50％ (28/32).Six patients had fever,8 patients had pain,and 2 patients had pleural effusion,and no patient had serious complication such as postoperative bleeding,biliary fistula or gastrointestinal perforation,etc.Five patients showed recurrence at 2,3,3,7 and 9 months after treatment,1 patient was treated with radio frequency ablation,1 patient was treated with microwave ablation again,2 patients were treated with γ knife,1 patient was treated with conservative method and then died of liver failure.The patients without recurrence were disease-free survival.Conclusions Laparoscope microwave ablation therapy has the advantages of laparoscope and microwave ablation.It is safe and feasible,with few trauma and outstanding curative effect,especially for the liver cancer in special site.

Three aspects of advances in study on the carcinogenicity of alga toxins are reviewed in this paper. Water pollution by alga toxins has become a worldwide environmental problem, and special attention has been paid to the potential carcinogenicity of microcystins, the main alga toxin. Results from the study on structure_activity relationship, short_term screening assay in vitro and long_term rodent carcinogenesis bioassay all showed that alga toxins possessed tumor_promoting activities. It suggested that inhibition of protein phosphatase activities, induction of expression changes of cell proliferation_related genes, dysregulations of signal transduction and cell proliferation might be the mechanisms of the carcinogenesis effect of alga toxins.
