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.

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.

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.

Objective To evaluate the therapeutic effect of total mesorectal excision in radical operation of rectal carcinoma.Methods From 1997 to 2007,126 consecutive patients with middle and inferior rectal carcinoma underwent surgical operation according to the principle of total mesorectal excision.Results Two patients(1.6%) died of postoperative pulmonary infection,and postoperative anastomotic leakage occurred in 2 cases(1.6%).The postoperative follow-up of 1-5 years showed that local recurrence rate 2 years after surgical operation was 4%(5/126),the 3-,5-year survival rate was 93.6%(116/124) and 84.7%(105/124),respectively.Conclusions Total mesorectal excision can decrease the frequency of postoperative local recurrence of rectal cancer without increasing complications as long as its correct indications are selected.

Objective To evaluate and compare the efficacy and toxicity of gemcitabin(GEM) plus cisplantin and GEM on the chemotherapy of elderly patients advanced non-small-cell lung cancer (NSCLC).Methods 85 elderly patients with stage 3 to 4 NSCLC were randomized into gemcitabine plus cisplatin (group GP) and GEM (group GEM).In group GP,patients received GEM on day 1 and day 8 at dose 1.0 g/m2,add cisplatin on day 2 to day 4 at dose 75 mg/m2. In group GEM, patients would received single GEM at dose 1.25 g/m2.The the therapy circle was 3 weeks and undertaken least 2 circles before the treatment efficacy and survival would be evaluated according RECIST. Results In GP group the response rate was 48.84 ％(21/43),In GEM group the response rate was 35.71％(15/42),the difference of response rate between two groups was not statistically significant(x2=1.708,P=0.424).The median survival were 11 months to Gp group and 9 months to GEM group. The 1 year survival rates of GP group were 39.53 ％ and of GEM group were 26.19 ％. The survival time between two groups was not statistically significant(t=1.377,P=0.172).The same toxicity in both groups was defected, Nausea and vomiting occurred were more serious in GP group than that in GEM group (x2=9.796, P=0.002). Conclusion GP and GEM are both effective for treatment of elderly advanced NSCLC.There are no significantly differences on efficacy and toxicity in 2 groups. Side effects on alimentary system are obviously less in GEM group than that in GP group.

Objective To explore the relationship between type D personality,anxiety and depression of coronary heart disease(CHD) and the effects on quality of life (QOL).Methods 296 CHD patients were randomly chosen to answer the questionnaires of general situation,type D personality scale (DS14),Self-rating Anxiety Scale(SAS),Self-rating Depression Scale (SDS) and Short-Form Health Survey (SF-36).Results Of all subjects 37.2％ were identified as type D personality,detection rates of anxiety and depression was were higher than the patients with non-type D personality (33.6％ vs 14.0％,49.1％ vs 23.1％,separately) (P＜ 0.01).The scores of role-physical (RP),bodily pain (BP),general health (GH),vitality (VT),social functioning (SF),role-emotional(RE),mental health (MH) in patients with type D personality ((32.73 ± 42.52),(57.68 ± 26.93),(42.14 ±18.23),(47.15 ±22.60),(59.43 ±26.67),(45.91 ±46.22),(49.25 ±22.21),separately) were lower than the patients with non-type D personality ((56.00 ± 46.61),(64.62 ± 22.27),(48.27 ± 19.19),(61.56 ±20.17),(69.70 ± 24.35),(70.79 ± 44.53),(70.52 ± 18.91),separately) (P＜0.05 or 0.01).Multiple stepwise regression analysis showed that depression,type D personality,anxiety,coronary artery stenosis degree and degree of education were entered QOL regression equation(β =-16.31,-6.53,-7.69,-15.75,2.64,P ＜ 0.05).Conclusion The type D personality of CHD exist high prevalence of anxiety and depression disorders,and the type D personality influence the QOL of patients with CHD.

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.
