Objective A method was developed for the determination of cyanide in water by ion chromatography with direct amperometric detection.Methods The eluent used was 0.1 mol/L NaOH and 10%(V/V) acetone.The samples were analyzed by using ion chromatography as well as external standard curve.The effects of 7 common ions,2 electrochemical active substances on the determination of cyanide were studied.Results The linear range of the method was 0.05-100 ?g/L and the correlation coefficient was 0.999 1.The RSD was

The experimental right cerebral contusion model was established in rats.To observe the relationship between the expression of Nitric oxide synthase 1(NOS1)and time elapsed after cerebral contusion,the expression of Nitric oxide synthase 1(NOS1)and mRNA was studied by immunohistochemistry and in situ hybridization at different intervals after cerebral injury.The results indicated that a positive relationship existed between the expression of NOS1 and NOS1 mRNA and the intervals elapsed after brain injury.This method also can be used to distinguish antemortem and postmortem injury rat′s cerebral contusion.So that,the expression of NOS1 and NOS1 mRNA is of great value for timing of brain injury.

Objective To observe characters of sputum of patients with tracheotomy by heat and moisture exchanger(HEM)undergoing hyperbaric oxygen therapy(HBOT)in multi-person chamber.Methods In randomly block design,239 patients were selected and received HBOT using HEM combined with L-shape tube(group HEM,n=128)and by L-shape tube(group L,n=111)respectively.The characters and volume of sputum,times of sucking sputum and cases of sealing/extubation of tubes were assessed over first and tenth sessions of HBOT.Results The times of sucking and volume of sputum over first session of HBOT in the group HEM were more than those in group L.The sputum was changing from ropiness over first session to tenuity over tenth sesion(P＜0.01).Cases with sealing/extubation of tubes in group HEM were more than those of group L(P＜0.01).Conclusions It is helpful to humidify and discharge deposited sputum of patients over routine hyperbaric oxygen by HEM.And the case8 of sealing/extubation of tubes are also reduced.

Objective To study the effects of classification-partition-distribution emergency nursing management for severe trauma patients. Method A total of 60 patients from June 2014 to May 2015 were set as control group receiving common nursing and other 62 patients from June 2015 to June 2016 as observation group treated with emergency hierarchical partition and triage nursing. Result The treatment success rate in the observation group were both significantly higher than that of the control group (P<0.05). Conclusion Classification-partition-distribution emergency nursing management for severe trauma patients can increase treatment success rate .

OBJECTIVE:To establish the method for the detection of the known glucagon-like peptide 1 receptor (GLP1R) gene mutation site rs3765467(NT_007592.16,position:39065819),and to evaluate its accuracy and practicability. METHODS:Peripheral venous blood samples of 72 healthy subjects were collected in medical examination center of our hospital during Oct. 2015-Feb. 2016. The whole blood DNA was extracted by column extraction method. After amplified by touch down PCR,high reso-lution melting(HRM)method was adopted to analyze amplified product. Sequencing verification by double stranded chain termina-tion method(Sanger sequencing method)was performed for 38 test samples. The results of 2 methods were compared. RESULTS:The results of mutation scanning showed that there were 39065817 and 39065819 polymorphism sites in amplified segments. Four types of mutations were detected by HRM method [GCG/GCG,GCA/GCG or ACG/GCG,GCA/GCA or ACG/ACG,A(G) CA(G)],but 6 types of mutations was detected by Sanger sequencing method [GCG/GCG,ACG/GCG,ACG/ACG,A(G)CA (G),GCA/GCG,GCA/GCA]. CONCLUSIONS:HRM method can identify GCG/GCG and A(G)CA(G)genotype,but can not identify GCA/GCG and ACG/GCG heterozygous mutation,GCA/GCA and ACG/ACG homozygous mutation. The method is not suitable for the detection of single nucleotide polymorphism for multiple neighboring sites. In the detection of single nucleotide mu-tation,economical and simple method should be selected after comprehensive analysis of sequence.

OBJECTIVE:To evaluate the therapeutic effect of clarithromycin on prostatitis induced by NG,CT and U?U.METHODS:56cases of venereal disease-related prostatitis were treated with oral clarithromycin in combination with prostatic massage and hip bath.7days after withdrawing drug,examination of prostatic secretion(EPS)and detection of pathogens were carried out.RESULTS:Total effective rate was82.1%;negative turn rate was92.9%;87.5%EPS routine came back to normal;no obvious ARDs were found.CONCLUSION:Clarithromycin is high in therapeutic effect,slight in ad?verse reactions and convenient in administration.It is suitable for treatment of venereal disease-related prostatitis.

Objective To observe the clinical efficacy of Qingjinchangfei drink for treating AECOPD.Methods We Used random number table to separate 84 patients in to two groups:treatment group and control group.The treatment group used western medicine conventional treatment and Chinese medicine decoction Qingjinchangfei drink.The control group used western medicine conventional treatment.Both two groups were 14 days treatment.We recorded the improvement of symptoms and signs everyday.We compared the lung function,inflammatory cytokines,such as IL-8、IL-2 before and after treatment in the two groups.Results The total efficient in treatment group was obviously better than that in control group.The indicators such as clinical symptoms,signs,pulmonary function indicators were obviously better than that in control group.Compared with before treatment,IL-8,ET,MDA and TNF-? in sputum and blood were obviously lower but IL-2 was obviously higher.Conclusion Qingjinchangfei drink plus western medicine conventional treatment for treating AECOPD was obviously better than western medicine conventional treatment.
