Objective To assess the predictive value of plasma level of calcitonin gene related peptide for cardiovascular events and operational stent restenosis after coronary stent implantation in 6 months.Methods Plasma level of CGRP was measured in 53 cases of coronary stent implantation before and after the operation.The cardiovascular events and the stent restenosis were observed and recorded in 6 months after the procedure.Results The plasma level of CGRP was significantly lower in patients with cardiovascular events and stent restenosis(166.36?10.18,182.5?11.36,P

Objective To explore the situation of return-to-work (RTW) and its related factors in female injured works. Methods The da-ta of the basic information, counseling record and follow-up record after discharge were collected from social rehabilitation department in our center. The main influencing factors were analyzed by single factor analysis and two classification Logistic regression. Results 232 ob-jects were collected, among which, 149(64.2%) subjects had returned to work, and the median of absence time was 206.5 days. Single factor analysis indicated that their age, marriage, absence time and educational level were not correlated with the outcome of women injured work-ers' employment (P>0.05). However, place of social insurance, household register and injury severity correlated with the outcome (P<0.05). Conclusion Most of the female injured workers can return to work. The severity of injury, along with some system factors influence the RTW of them.

Objective To observe the morphology and ultrastructure of Blastocystis hominis. Methods Morphological observation was made with 4-5 days cultured B.hominis by light microscopy, and similar material fixed with 4% glutaraldehyde was used for transmission electron microscopy. Results Several forms of B.hominis were observed including vacuolar, \{granular\}, amebic, multifission and cystic forms. The multiplication patterns of B.hominis included both binary fission and sporogony. Under transmission electron microscope, the nuclei, mitochondria, rough endoplasmic reticula and lysomes were observed in addition to lipid droplets in its cytoplasm, and glycogen in the central vacuole. Conclusion The central vacuole of vacuolar form may be related to the storage of the excreta. The amebic form of B.hominis might be pathogenic.

Objective To determine whether it is necessary to execute pre-labor pubic shaving.Methods Women(336 cases)who received pubic shaving through vaginal delivery from 2003 to 2006 were set as the control group.Women(103 cases)who were waiting for delivery currently in our hospital were set as the test group.The test group only received perineal cleaning without pubic shaving.If episiotomy was needed during the operation,the perineal hair Was cut by scissors.The perineum infectious rate and postpartal infection Was compared in the two groups.We interviewed the patients attitude for pubic shaving and counted the numing time used for pubic shaving.Results The perineal infection in the test group was 5.8%,which was no statistically different from that of the control group(2.4%),U=0.33,P＞0.05.Totally 95% women in the test group support this method demonstrated humanization.In the telephone folow-up visit for patients in the control group they comphined itch and discomfort during the regeneration of pubes.The average numing time for pubic shaving Was(4.6±0.6)minutes.Conclusions No pubic shaving for pre-labor skin preparation was feasible.If operation was disturbed by pubes we could use scissors to cut it short.This method could reduce the skin infection and propagation of blood-derived infectious disease.It increased the comfort of parturient,saved time and proved to be a nursing method of humanization.

Objective To investigate the protective effects of erythropoietin (EPO) on myocardium injury after sepsis in rats in order to clarify the mechanisms.Methods The rat models of sepsis were produced by cecal ligation and perforation method (CLP).Ninty-six healthy SD rats were randomly (random number) divided into 3 groups:the sham operation group (Sham group,n =32),the sepsis group (CLP group,n =32),and the EPO treatment group (EPO group,n =32) treated with EPO 1000 IU/kg intraperitoneal injection after the CLP.The observation intervals were set at 3 h,6 h,12 h and 24 h after the surgery.The cardiac hemodynamics of the CLP group were measured.Plasma levels of inflammatory factors and myocardial enzyme indicators were determined by enzyme-linked immunosorbent assay (ELISA) ; Membrane potential levels of chondriosome of myocardial cells,cell apoptosis rates and expressions of nuclear factor-κB p65 of myocardium tissue were detected by flow cytometer; Then the pathological change of myocardium with HE staining was observed under light microscopy.Results (1) Compared with the CLP group,left ventricle systolic pressure (LVSP),left ventricle diastolic end pressure (LVEDP),the maximum rate of left ventricle rise and fall (+ dp/dtmax and-dp/dtmax) in the EPO group improved (P ＜0.05,P＜0.01); (2) Compared with the Sham operation group,plasma levels of tumor necrosis factoralpha (TNF-α),interleukin-6 (IL-6),C-reactive protein (CRP),cardiac troponin-I (cTNI),creatine kinase (CK),lactate dehydrogenase (LDH) and glutamine-oxaloacetic transaminase (GOT) in the CLP group increased at each interval (P ＜ 0.05),and those biomarkers in the EPO group were lower than those in the CLP group (P ＜ 0.05) ; On the contrary,plasma level of anti-inflammatory factor IL-10 in EPO group was higher than that in the CLP group (P ＜ 0.01) ; (3) Compared with the Sham operation group,the cell apoptosis rates in the CLP group increased significantly (P ＜ 0.01),and it decreased obviously in the EPO group (P ＜ 0.01); (4) Compared with the Sham group,membrane potential levels of chondriosome of myocardial cell in the CLP group decreased (P ＜0.01),while it increased in the EPO group in comparison with the CLP group (P ＜ 0.01) ; (5) Pathological changes of myocardium after the CLP could be lessened by the EPO treatment.Conclusions EPO may increase membrane potential levels of chondriosome and decrease the apoptosis rates of myocardial cell in rats after sepsis,and it may reduced the production of inflammatory factors to protect the myocardial cell by down-regulating NF-κB p65.Both increased membrane potential level of chonriosome and decreased inflammatory factor may implicate in myocardium protection thereby improving cardiac function after sepsis.

Objective To investigate the incidence of insomnia in patients with nasopharyngeal carcinoma during radiotherapy and analyze the influencing factors.Method A sleep quality questionnaire for patients with nasopharyngeal carcinoma during radiotherapy was designed and used for the investigation of the incidence of insomnia as well as the influencing factors related to insomnia.Results The incidence of insomnia was 42.2%.Univariate analysis revealed that radioactive xerostomia,nausea,hospital environmental noise,radioactive oral mucositis,worry about job,worry about prognosis,burp,vomiting,worry about family influence were related to insomnia in nasopharyngeal carcinoma patients during radiotherapy;multivariate analysis showed that radioactive oral mucositis,environmental noise and job stress were the independent factors leading to insomnia(All P<0.05).Conclusions There is a high incidence of insomnia in patients with nasopharyngeal carcinoma during radiotherapy.Radioactive oral mucositis,environmental noise and job stress might be the independent factors relative with insomnia during radiotherapy.

Objective To explore the correlation and significance of V312F locus polymorphism of PCSK9 gene in patients with coronary heart disease.Methods We selected 3560 patients with coronary heart disease who came to our hospital from January 2014 to January 2016 as the case group.They were divided into 5 subgroups:angina group,myocardial infarction group,silent myocardial ischemia group,ischemic cardiomyopathy group,and sudden death group,according to their anatomic and pathophysiological features.Data of 1 000 people for physical examination served as the control group.PCR assay combined with direct sequencing method was applied to test V312F locus polymorphism of PCSK9 gene.Logistic regression analysis was used to analyze relationship between V312F locus polymorphism of PCSK9 gene and types of coronary heart disease.The concentration of serum PCSK9 and lipids of the two groups were also measured.Results The serum levels of PCSK9,TC,TG and LDLC and ratio of positive family history in the case group were significantly higher than those in the control group,while the level of HDLC was lower than that of the controls (all P＜0.05).Indexes of sudden death subgroup in the case group showed the most significant changes,while asymptomatic myocardial ischemia subgroup showed the weakest changes.The frequency of genotype TT,GT and allele T in the case group was 3.4％,16.6％ and 11.7％,respectively,which was significantly higher than that in the control group (1.1％,10.2％ and 6.2％) (all P＜0.01).The highest frequency of genotype TT,GT and allele T was found in sudden death subgroup,and the lowest frequency of these indexes was found in asymptomatic myocardial ischemia subgroup (P＜0.05).Results of Logistic regression analysis showed that genotype TT in V312F locus of PCSK9 gene was related to the severity of coronary heart disease (OR =8.463,95％ CI from 3.505 to 17.854,P＜0.001).Conclusion The mutation of V312F (T/G)locus of PCSK9 gene might be related to the severity of coronary heart disease.
