1.Analysis on clinical significance of Acinetobacter baumannii isolated from patients′sputum samples in cerebral surgery ICU
International Journal of Laboratory Medicine 2015;(5):624-625
Objective To understand the clinical distribution and drug resistance situation of112 strains of Acinetobacter Bau-mannii isolated from the patients′sputum samples in cerebral surgery ICU in order to provide the basis for the rational use of anti-bacterial drugs in clinical therapy.Methods 112 strains of Acinetobacter Baumannii were performed the retrospective analysis.The VITEK2-Compact automatic microbiological analyzer was adopted to conduct the bacterial identification and the drug susceptibility test and the K-B method was combined as the supplement control.The Whonet 5.6 software was used for conducting the statistical analysis.Results Among 112 strains of Acinetobacter baumannii,75 strains(67.0%)were multi-drug resistant,8 strains(7.1%) were pan-resistant.The antimicrobial susceptibility tests showed that the resistant rates of Acinetobacter baumannii to mezlocillin, piperacillin and nitrofurantoin reached up to 100%.Acinetobacter Baumannii had the lower resistant rate to polymyxin B (2.7%), the resistant rates to minomycin and ceperazone/sulbactam were 4.5% and 10.7% respectively.Conclusion The drug resistance phenomena of Acinetobacter Baumannii in the cerebral surgery department ICU is serious.Minomycin,polymyxin B and ceperazone/sulbactam have the better antibacterial activities to clinically isolated Acinetobacter Baumannii and may be the alternative drugs for therapy.Clinic should strengthen the monitoring and rationally use the antibacterial drugs.

International Journal of Laboratory Medicine 2015;(8):1084-1085,1087
Objective To investigate the correlation of Helicobacter pylori (HP) infection and serum carbohydrate antigen 724 (CA724) level .Methods 229 patients with HP infection hospitalized in gastroenterology department were enrolled in the observa‐tion group ,and patients were divided into different disease group according to the results of diagnosis .Other 100 healthy people , conducted physical examination ,were enrolled in the healthy control group .The HP infection was detected by 13C‐urea breath test and the serum CA724 level was detected by chemiluminescent immunoassay .Results The HP value and serum CA724 levels in each disease group were higher than those in the healthy control group ,with significant differences(P<0 .05) .The HP value was highest in the duodenal group ,and there was no statistical differences between each disease groups (P>0 .05) ,except the duodenal group .The serum CA724 level was highest in the gastric cancer group ,there was no statistical differences between each disease groups(P>0 .05) ,except the gastric cancer group .The serum CA724 level was positively correlated with HP value in patients with HP infection(r=0 .331 ,P<0 .01) .Conclusion HP infection may correlate with serum CA724 level .The serum CA724 level in the gastric cancer group increased more significantly ,in other disease groups increased steadily .Dynamic observation of serum CA724 level in patients with upper gastrointestinal tract disease associated with HP infection could be helpful for early diagnosis and pre‐vention of aggravation of lesions ,and could provide effective diagnosis basis for early detection of upper gastrointestinal tract le‐sions ,such as gastric cancer .

6.Research progress of histone methylation in arsenic induced T cellular immune injury
Chinese Journal of Endemiology 2017;36(2):147-151
In recent years,the influence of endemic arsenic poisoning on immune system has caught people's attention.Changes in histone modification patterns may be one of the mechanisms of arsenic regulated gene expression,arsenic plays an important role in differentiation,proliferation and function of immune cells.Arsenic has a certain effect on the differentiation and function of T cells,and it is rarely studied whether the process is regulated by histone methylation.In this paper,the study of histone methylation in arsenic induced T cellular immune damage is reviewed.
7.Analysis of the effect of naloxone in the pre-hospital care of AOPP
Chinese Journal of Postgraduates of Medicine 2015;38(z1):102-104
Objective To investigate the effect of Naloxone in the pre-hospital care of AOPP.Methods 54 patients with the pre-hospital care of AOPP were divideded into two groups.The treatment group was treated with Naloxone,Atropine and Pyridine aldoxime methyliodide,the control group treated with Atropine and Pyridine aldoxime methyliodide,and the results were analyzed using t-test and x2 test.The efficacy of the two groupswas compareded.Results In the treatment group,the mumber of drug delivery and the dosage of Atropine were less.The recovery time of the actirity of Cholinesterase and the patients coma were shorter.Complications and mortality was significantly lower,but the cure rate was significantly higher than that of the control group.Conclusion Naloxone is effective and safe in the treatment the pre-hospital care of AOPP.It is worthy of clinical promotion.
8."Probe into the preliminary application of micro-Seminar in ""Pediatric Nursing"" teaching"
Chinese Journal of Practical Nursing 2015;31(11):841-844
Objective To reform the traditional teaching methods,and to explore the feasibility and effect of micro-seminar applied in Pediatric Nursing teaching.Methods A total of 151 undergraduate students of nursing admitted in the year of 2011 were selected as the experimental group,using micro-Seminar teaching method,while 152 undergraduate students of nursing admitted in the year of 2010 as historical control (the traditional teaching group).The application effect of micro-Seminar in Pediatric Nursing teaching was investigated and evaluated.Results Students of micro-seminar group got higher score in the final examination than students of the traditional teaching group [(81.34 ± 8.34) vs.(78.40 ± 8.03)],and the difference was statistically significant (P<0.05).Micro-seminar was accepted by 92.7% of students of the experimental group as a new teaching method,and students unanimously affirmed it was beneficial to enhancing their individual abilities of learning,cooperation,communication,and expression.Conclusions Micro-seminar pedagogy could help cultivating students' comprehensive abilities and improving teaching effect and quality.As was high operability,micro-Seminar was worth applying and popularizing.

BACKGROUND: There are several ways for treating the trigeminal neuralgia, such as medication, block therapy and surgery, etc. But few reports throughout the world described stereotactic radiotherapy(SRT) for it, which is efficient, non-invasive and painless.OBJECTIVE: To investigate the improvement of SRT for trigeminal neuralgia.DESIGN: Case analysis based on patients.SETTING: X-knife Treatment Center, First Affiliated Hospital, Henan University of Science and Technology.PARTICIPANTS: Totally 30 patients with trigeminal neuralgia were selected from X-knife Treatment Center, the First Affiliated Hospital of Henan Science and Technology University between March 1999 and March 2002. All patients were diagnosed with CT or MRI, and no other diseases were found. Patients without obvious effect from a long-term medicine treatment or surgery were selected as the investigative subjects.METHODS: Thirty patients with trigeminal neuralgia wearing face cover were treated with non-coplanarity fractional stereotactic radiotherapy. The patients received 2 target regions and peripheral does of 60 - 75 Gy. 5 mm collimator and isodose curves referred to ranged from 85% - 90%.MAIN OUTCOME MEASURES: Results of therapeutic assessment and follow up.RESULTS: The follow up period ranged from 1 to 22 months. Among 30patients, 6 patients' symptoms were lightened or eased up over 12-24hours, 20 patients received a marked effect over 1 - 3 months, 4 patients'treatment effects were not obvious. The effect rate reached 87%. A patient occurred numbness in sick face, and a patient showed no obvious effect in the first treatment, but the efficacy became evident in the second treatment.CONCLUSION: It is efficient in the treatment of trigeminal neuralgia with stereotaetic radiotherapy and there is no special side effect.
