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.

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.

Objective To assess the clinical effects of supracapsular implantation with optic capture of the posterior chamber intraocular lens in pediatric cataract.Design Retrospective case series.Participants 15 cases(17 eyes)with pediatric cataract.Methods Phacoemulsification,posterior continuous curvilinear capsulorhexis,about 4 mm in diameter,supracapsular implantation with optic capture of the posterior chamber intraocular lens in pediatric cataract were performed.Main Outcome Measures Preoperative and postoperative visual acuity,intraocular pressure,position of IOL,intraoperative and postoperative complications.Results Implantation of optic capture of the posterior chamber intraocular lens was successfully performed in 17 eyes.Positions of IOL were changed in 5 eyes after operation 6 months,from post-capsule to supra-capsule.Among these 5 eyes,opaque optic axis were found in 4 eyes.No optic axis opaque was found in 13 eyes with optic capture.The major complications of optic capture were lenticular precipitates:grade 1 in 3 eyes(18%);grade 2 in 7 eyes(41%).Anterior synechia of iris occurred in 1 eye(6%);posterior synechia of iris in 4 eyes(24%).Pupil deformity occurred in 5 eyes(29%).Conclusions Posterior continuous curvilinear capsulorhexis and supracapsular implantation with optic capture of the posterior chamber intraocular lens are safe and effective in the treatment of pediatric cataract,especially in the prevention of secondary opacification from the visual axis.

Objective To discuss the relationship between C-reactive protein and prognosis of acute coronary syndrome. Methods C-reactive protein of 60 acute coronary syndrome patients was evaluated. The individuals were divided into two groups:One group with higher CRP level and another group with normal CRP level. The following-up duration was 6 months. After correct therapy, the morbidity of re-angina, arrhythmia, heart failure, re-infarction and cardiac death was compared. Results The morbidity of re-angina, arrhythmia, heart failure, re-infarction, cardiac death was 46.3%(19/41), 43.9%(18/41),9.76%(4/41),22.0%(9/41),7.32%(3/41)respectively in higher CRP level group; The morbidity of re-angina, arrhythmia, heart failure, re-infarction was 15.8%(3/19),10.5%(2/19), 5.3%(1/19),5.3%(1/19)respectively in normal CRP group and there was no cardiac death accident. There was significant different between the two groups. Conclusions CRP plays an important role in the onset of acute coronary syndrome, and its level is related with the higher morbidity of re-angina, arrhythmia, heart failure, re-infarction and cardiac death.

Functional near-infrared spectroscopy is a non-invasive optical brain function detection technology,which can do multi-point measurement of changes on cerebral cortical area corresponding to the oxygenation of the blood hemoglobin and deoxygenated hemoglobin concentration,and then reflect the state of brain cortex function.Its greatest advantage is to allow the subjects head moving in a certain range,especially suitable for children.At present this technology could be applied to clinical pediatric,such as epilepsy,autism,attention deficit/hyperactivity disorder,neonatal disease,neurosurgery and cardiovascular surgery,etc.Functional near-infrared spectroscopy technology will have more applications in the field of research on brain function.
