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.

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.

We studied the effects of the oxygen on partial nitrification in a membrane bioreactor (MBR), to find out critical dissolved oxygen (DO) concentrations for the optimal partial nitrification by monitoring the oxygen uptake rate (OUR) and oxygen supply rate (OSR). The nitrite accumulation occurred at a DO concentration of 1 mg/L, while the ratio of nitrite to ammonia in effluent was close to 1 at a DO concentration of 0.5 mg/L which was suitable to serve as the feed of an ANNAMOX system. When the mixed liquid suspended solids(MLSS) was 20 g/L in MBR, OUR and OSR were 19.86 mg O2/(L·s) and 0.369 mg O2/(L·s) respectively, indicating that the oxygen supply was the bottleneck of partial nitrification. "Low DO and high aeration rate" were suggested as a control strategy to further improve the efficiency of partial nitrification.

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 investigate the value of genetic testing in clopidogrel individualized antiplatelet therapy for acute coronary syndrome(ACS)patients after percutaneous coronary intervention(PCI). METHODS:Clinical pharmacists participated in therapy for 3 ACS patients after PCI,and analyzed risk factors of stent thrombosis as the degree of lesion complexity,length and number of stents,complication,smoking history,etc. Clinical pharmacists suggested conducting clopidogrel genetic testing (CYP2C19,PON1,ACBC1),and suggested replacing antiplatelet agents,maintaining original plan and strengthening monitoring according to the results of genetic testing. RESULTS:The physicians adopted the suggestions of clinical pharmacists. After optimiz-ing antiplatelet therapy according to the results of genetic testing and clinical factors,3 patients were stable and discharged from hospital with drugs. CONCLUSIONS:Genetic testing can provide evidence for the formulation of individualized antiplatelet thera-py in ACS patients after PCI,and can be regarded as one of the breakthrough points for clinical pharmacists to carry out pharmaceu-tical care. In conducting genetic testing,clinical pharmacists should evaluate the risk of thrombosis in ACS patients and select the appropriate population for testing. At the same time,the clinical factors as medication compliance,stent thrombosis risk,therapeu-tic efficacy,ADR,and evidence-based pharmaceutical evidence should be comprehensively evaluated on the basis of genetic test-ing,and antiplatelet therapy plan should be optimized so as to guarantee the safety and effectiveness of drug use.

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.

BACKGROUND:It can be confirmed by the clinical trial that chronic plantar fasciitis can be treated by extracorporeal shock wave.There are some different explains for the mechanism of action.OBJECTIVE:To introduce the mechanism of action and clinical application of extracorporeal shock wave in the treatment of chronic plantar fasciitis.RETRIEVAL STRATEGY:A computer-based search was conducted in PUBMED,HighWire and Springer databases for articles published before August 2007 with the key words of "chronic plantar fasciitis,extracorporeal shock wave application" in English by the first and second authors.Inclusive criteria:articles were selected firstly based on the mechanism of action and clinical application of extracorporeal shock wave for chronic plantar fasciitis.Exclusive criteria:articles out-of-date and repeated were removed.LITERATURE EVALUATION:Sixty-five relevant articles were collected,and twenty-five met the inclusive criteria.Of them,4 articles were review,and others were about the mechanism of action and clinical application of extracorporeal shock wave for chronic plantar fasciitis.DATA SYNTHESIS:①Someone believed that high energy shock wave selectively damaged unmyelinated sensory nerve fibers.Low energy shock wave could inhibit the conduction of sensory nerve ending by releasing calcitonin-gene-related peptide and producing neurogenic inflammation.It also could play a long-term analgesic effect by making the changes in regional flow of the brain,regulating pain memory and reducing local stimulatory response.②There are many reports on short-term and long-term outcomes,different energy levels,local anesthetic drug,the depth of plantar fasciitis and therapeutic place.CONCLUSION:It is effective to treat chronic plantar fasciitis by extracorporeal shock wave.Different approaches can bring us different therapeutic outcomes.

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.
