Objective To determine the mercury in seven kinds of algal plant drugs.Method The mercury in the samples was determined by the atomic fluorescence spectrometry after been digested by microwave.Results The detection limit of mercury was 0.045?g?L~(1).The relative standard deviation was 1.65% and the average recovery was 97.77%.Conclusion The method had the advantages of simple operation,higher precision,higher sensitivity and repeatability and was suitable for the determination of mercury in the algal plant drugs.

Objective To investigate the epidemiological characteristics of imported malaria in Hailing District ,Taizhou City,so as to provide the evidence for formulating the effective prevention and control strategy. Methods The network reports, questionnaires and epidemic reports of imported malaria cases in Hailing District from 2010 to 2015 were collected and analyzed retrospectively. Results From 2010 to 2015,totally 46 cases of imported malaria were reported,including 40 cases of falci?parum malaria(86.96%),4 cases of ovale malaria(8.70%),1 case of quartan malaria(2.17%)and 1 case of multi?infection of falciparum malaria and tertian malaria(2.17%). No seasonal trend of time of the disease onset was observed. All the patients were return abroad with clear residence histories in malaria epidemic areas. The average time from disease onset to definite diag?nosis was 2 d and 8 patients were definitely diagnosed within 24 h. All the 46 patients were cured. Conclusion All the malaria cases reported were imported cases in Hailing District in the last five years. Effective prevention and control measures are the key to the malaria elimination.

Objective To understand the current status of Oncomelania hupensis snails and the change rules,so as to pro?vide the evidence for formulating the snail control strategy. Methods The data of snails were collected and the factors influenc?ing the changes of snail status were investigated,and all the data were analyzed in Hailing District from 2007 to 2014. Results There were 18 environments with snails in 17 villages of 3 townships in Hailing District from 2007 to 2014. The snail area was 7.832 4 hm2. Among these environments and snail areas, 6 environments and 2.134 5 hm2, snail area were detected by the village snail investigation groups, and 12 environments and 5.697 9 hm2 snail area were detected by the township snail investigation groups. In addition, in 5 non?endemic villages, 3.126 3 hm2 snail area was found. In 2008, 2012 and 2013, a total of 2.274 0 hm2 snail area was found again. Conclusions In recent years,the snail situation rises again after schistosomiasis transmission has been interrupted. Therefore,this situation should be paid attention to.

High-consuming group is a special group which has good economic base, differmental culture and relgional belif customs. These patients alwanys need high quality medical service. How to integrate with these characteristics and make the nursing model of making patients' belife, moral ideas respcted, and rights proteded is a difficult problem. The author put forward we should rule nurse staff' s ethics and actions, provide a medical envionment from which can meet high-consuming patients physical and mental needs.

In recent years the incidence of acute kidney injury (AKI) has increased, with a high mortality rate and poor prognosis.The key of improving the prognosis of AKI is early diagnosis and intervention.Due to the lack of biomarkers of early diagnosis in AKI, the effective early treatment is generally delayed.Traditional diagnosis biomarkers such as serum creatinine and blood urea are delayed and affected by various factors.Recently, some new potential early diagnostic biomarkers have been found.MicroRNA(hereinafter referred to as the miRNA) is a kind of endogenous non-coding small RNA, and studies have shown that it is related to the development of AKI.

12 months in 36 patients),during the follow-up 2 patients died.Conclusions The DST is minimally invasive for the treatment of low rectal carcinoma with high rate of anus conservation,and can improve the life quality of the patients.

Tissue engineering has been a newly developed discipline which represents the new direction of biological medicine engineering.With evergrowing researches on the reparation of bone defect by tissue engineering,great success has been achieved in this field.The three important elements of bone tissue engineering are seed cells,cytokines and cellular biological scaffolds.Bioceramic is an important part of bioactive frame applied widely in tissue engineering.This paper presents a review of the application of bioceramic in the reparation of bone defect,which aims at promoting a systematic knowledge of the application of bioceramic in tissue engineering.

Objective To investigate the incidence of drug resistance among new and retreatment TB patients from special hospital.Methods Totally 500 smear positive TB patients from June 2013 to December 2014 in Beijing Chest Hospital were enrolled.Phenotypic susceptibilities to cultured isolates were analyzed in 15 anti tuberculosis drugs by MGIT 960,include Isoniazid (INH),Rifampicin (RFP),Streptomycin (STR),Ethambuto (EMB),Kanamycin (Km),Amikacin (Am),Capreomycin (Cm),Ofloxacin (Ofx),Levofloxacin (Lfx),Moxifloxacin (Mfx),Paza-aminosalicylate (PAS),Protionamide (Pto),Linezolid (Lzd),Ethionamide (Eto),Pyrazinamide (PZA).Results A total of 500 TB cases were enrolled.71 samples among these were NTM infection and 12 samples were contaminted.The rest of 417 of cases infected with Mycobacteriuma,and the rate of drug resistance was 47.2％ (192/417) and the MDR rate was 28.2％ (120/417).The retreatment was significantly higher than that of the new in any drug resistance rate and MDR rate (P =0.000).100 of the retreatment isolates and 50 of the new isolates with Mycobacteriuma were selected to do the drug susceptibility test in 11 subsequent anti tuberculosis drugs (include:PZA,Am,Km,Cm,Ofx,Lfx,Mfx,PAS,Pto,Lzd,Eto).Five cases were contaminated,and in the rest of the cases,48 was the new and 97was the retreatment.The rate of the drug resistance to PZA,Am,Km,Cm,Ofx,Lfx,Mfx for the retreatment were significantly higher than the new (P ＜ 0.05).The rate of drug resistance to PAS,Pto,Lzd and Eto for the new and reteartment were no markedly differential in statistics.Conclusion This study further confirmed the rate of drug resistance in retreatment cases is higher,and the management of tuberculosis patients should be further strengthened.

objectives To provide the reference for the Research & Development departments of hospitals by analyzing the quantity of publications and their cited status for the top 20 hospitals in SCl and MEDLINE.and top 100 hospitals in domestic publications in 2006.Methotis The number of publications and their cited times for the first 20 hospitals in SCI and MEDLINE.and the top 100 hospitals in domestic publications in 2006 were analyzed with bibliometric analysis.Results In 2006.the average increased ratio of publications in SCI for top 20 hospitals was 47.58%.but the number of articles in MEDUNE WaS decreased.For top 100 hospitals.the increased number of domestic publications was 71.25,the number of cited publications WaS increased 160.14.Conclusions The SCI publications from top 20 hospitals increased sharply,but publicatiOils indexed by MEDLINE decreased respectively.

Objective To study the effect of chitosan on the growth of the in vitro cultured retinal nerve cells. Methods The retinal nerve cells of SD baby rats were cultured in vitro. The effects of chitosan at 0.065%,1.25%,2.5%,5%,10%,15% on the growth of the retinal nerve cells were measured by MTT method. The blank control group was created. Results 1.25%,2.5%,5%,and 10% chitosan could obviously promote the growth of retinal nerve cells,and 10% chitosan was the optimal concentration for the growth of nerve cells. Conclusion Chitosan can effectively promote the growth of retinal nerve cells,and it is necessary to undertake the further study of Chitosan.
