Tourette syndrome(-TS) is a genetic predisposition,chronic complex neuropsychiatric disease in children.Recent studies focus on the relationship between TS and the genetic variations of susceptibility genes,particularly single nucleotide polymorphism (SNP).Highly automated,high accuracy and low cost of SNP detection and analysis technologies have promoted the study of hereditary diseases.The recent research development of SNP in TS related genes was reviewed in the paper.

Anaerobic ammonia oxidation (Anammox) is one of the important discoveries in the field of environmental microbiology, and it plays an indispensible role in the nitrogen removal from wastewaters and the biogeochemical nitrogen cycle. Through review research progress in anaerobic ammonia oxidation, an Anammox special issue is published so as to find problems, explore applications and outlook developments. The special issue consists of reviews and original papers, mainly involving in the following aspects: i) enrichment of Anaerobic ammonia oxidation bacteria (AnAOB); ii) community analysis of AnAOB; iii) preservation of granular AnAOB sludge; iv) effect of organic matter on Anammox; v) application of Anammox process, etc.

Objective To analyse the relationship between the diagnosis of disseminated intravascular coagulation(DIC) and the level of Thrombomodumin(TM),thrombin-antithrombin(TAT) and D-dimer in plasma from 67 patients with disseminated intravascular coagulation(DIC).Methods The levels of TM,TAT and D-dimer were measured by a two antibody sandwich enzyme linked immunosorbent assay and a latex aggregation assay.Results The levels of TM,TAT and D-dimer in plasma of patients with DIC were higher than those in control group(P

Objective To research the resistibility of microbes contaminated in cosmetics to preservatives in common use in cosmetics.Methods The minimum inhibitory concentration(MIC) method was used according to Disinfection Technical Guideline.Results The resuls showed that some of the isolated microbes had higher resistance for one or more of the commonly used preservatives.The MIC of enterobacter gergoviae for methyl paraben was 10 mg/ml,the MIC of paecilomyces for propyl paraben was 10 mg/ml,it was 2.5 times greater than the limited dose.The MIC of Pantoea,P.luteola and trichoderma for imidazolidinyl urea were higher than other standard microbe strains.Conclusion The microbes contaminated in cosmetics can develop tolerance to the preservatives in common use in cosmetics,maybe that is one of the causes for cosmetics contamination.

Objective To explore potential synergetic effects of interleukin-2(IL-2) with IL-18 on induction of natural killer(NK) cell activity against myeloma cells in vitro.Methods CD69 expression on NK cells were defined by Flow Cytometry;IFN-? level in supernatants of NK cell culture was measured by ELISA;pure NK cell population was obtained from peripheral blood by using cell purification kit;standard Cr51 release method was used to test NK cell cytotoxicity against myeloma cells in vitro.Results The combined application of IL-18 with low dose of IL-2(10u/mL) significantly enhanced NK cell activation,IFN-? secretion and NK cell cytolytic activity against myeloma cells(U266 and RPMI-8226) as compared to IL-18 alone,respectively.Conclusion IL-2 synergized with IL-18 to induce NK cells activates anti-myeloma cell in vitro and combined use of IL-18 and low dose IL-2 could be an alterative immuno-therapy approach for cancers including myeloma.

Objective To understand the antiseptic effect of preservatives commonly used in the actual cosmetics. Methods The single culture method was used to evaluate the effects of different preservatives on the different microbial. Results In the actual cosmetics, parabens could inhibit fungi well but bacteria, the effect of imidazolinyl urea was contrary, inhibited bacteria well but fungi. 2-bromo- 2-nitropropane-1, 3-diol got good effect. Methylchloro did not show an effect in the allowable range. Conclusion The cosmetics components are considered as the important influencing factors for the effects of preservatives used in the cosmetics.

Objective:To analyze the indicators and resistance rate of antibacterial drugs for special use in our hospital before and after the implementation of network online approval process to provide reference for the management and rational use of antibacterial drugs for special use. Methods:A retrospective analysis was performed, and the consumption amount, sales amount, utilization ratio, AUD, submission rate of microbial specimen and resistance rates for the main pathogenic bacteria of antibacterial drugs and ones for special use were investigated during 2012 and 2015 in our hospital. Results:The approval process of antibacterial drugs for special use developed from handwork to network online. The consumption amount of antibacterial drugs increased slightly year by year from 2012 to 2015 in our hospital, the mean expense of antibacterial drugs for the inpatients increased from 1602. 85 yuan to 1888. 63 yuan,and AUD increased from 54. 50 DDDs/(100 persons × d) to 65. 47 DDDs/(100 persons × d). The sales amount proportion of antibacterial drugs for special use (13. 90%) was the lowest in 2013, and the highest (17. 34%) in 2015, and AUD increased from 4. 85 DDDs/(100 person × d)to 6. 37 DDDs/(100 person × d), and the submission rate of microbial specimen before the treatment increased from 85. 5% to 90. 0%. The main pathogenic bacteria were Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa and Acinetobacter baumannii,and their ratio had slight change. Except Staphylococcus aureus, the resistance rate of the other four pathogenic bacteria kept increasing, and the resistance rates of Acinetobacter baumannii to cefepime and carbapenems were over 50%. Conclusion:The approval process management of antibacterial drugs for special use must be strengthened in order to truly a-chieve reasonable use of antibacterial drugs for special use.

Objective To discuss the selection of operation methods of total hysterectomy in obese women. Methods We reviewed clinical data of 116 obese women with the body mass index (BMI) ≥ 28 kg/m~2 treated with total hysterectomy. According to the operative procedure, 56 women underwent the vaginal total hysterectomy (Vaginal Group) and 60 women, abdominal total hysterectomy (Abdominal Group). Intra- and post-operative records were compared between the two groups. Results As compared with the Abdominal Group, the Vaginal Group presented a significantly shorter operation time (t=-3.693,P=0.000) and hospital stay (t=-7.019, P=0.000), a significantly less intraoperative blood loss (t=-4.006,P=0.000), and a significantly lower postoperative pyrexia rate (?~2=4.388,P=0.036) and complication rate (?~2=5.243,P=0.022). Conclusions Vaginal hysterectomy is superior to abdominal hysterectomy in obese women, but should be used with caution in those with severe adhesions or multiple abdominal operation history.
