Objective To investigate the clinical value of multi-slice spiral CT (MSCT)in diagnosis of internal abdominal hernia (IAH).Methods The MSCT findings in 1 5 patients with IAH confirmed by surgery were retrospectively analyzed.Results MSCT showed intestinal obstruction in 14 patients with strangulating intestinal obstruction in 8.The typical features of MSCT were as follows:translocated position of intestines (occupying effect),closed loop intestinal obstruction (gathered intestinal loops with different forms),assembled,expanded and translocated blood vessels of mesenteries,and thickened intestinal walls with ischemic edema and abnormal density.Surgical results showed paraduodenal hernia in 2,transomental hernia in 2,transmesenteric hernia in 5,ankylenteron strap hernias in 4,pericecal hernia in 1 and hernia through the Douglas fossa in 1,Intestinal obstruction in 14 and strangulating intestinal obstruction in 8 were also confirmed by surgery.The CT findings of IAH were correlated with the surgical results,and the accurate rate of grading of intestinal obstruction with CT was also consistent with the surgical results (Kappa=0.758,t=3.462,P=0.001).Conclusion IAH can be diagnosed accurately by MSCT in most patients,MSCT is helpful for guiding the surgical programs.

Objective The purpose of this study was to evaluate the disinfection effectiveness and properties of acrylic resin via microwave irradiation. Methods Forty acrylic resin base dentures fabricated in a standardized procedure were chosen and divided into Group A,B,C and D randomly. Group A,B and C were immersed in 200ml distilled water and submitted to microwave irradiation at 700W for 3,4,5 minutes individually. Group D was used as positive control. Bacteria specimens from each group were got for culture and numbers were calculated. Then the four groups were tested for the flexural strength and impact strength by universal test machine before and after microwave irradiation sterilization. Results The germicidal ratio of Group B was more than 90% ,while the ratio of group C was 100%. There was no significant difference in flexural strength and impact strength between group C and group D. Conclusions Microwave irradiation for 5 minutes at 700W produced sterilization of dentures contaminated with all bacteria whereas the denture strength is not affected. Microwave irradiation at 700W solution for 5 minutes was effective to sterilize acrylic resin base dentures.

Objective To explore the pressure of hospitalized patients and protrudent problem of mental stress.Methods Choosing 150 non-psychiatric patients in random for investigation using mental status scale in non-psychiatric patients.At last, data were analyzed to find out the stressors they were bear-ing in hospital.Results There existed mental pressures in hospitalized patients in some degree."to ex-pect to recover health early" was the highest score (7.21±3.17), and "to worry about their position de-creased after disease" got the lowest score, (2.56±2.15).The mental stress of hospitalized patients was cor-related with age, sex, education degree, income and marital status.Conclusions There existed mental pressures in hospitalized patients in some degree.Different mental stressor shows different psychological re-action, we should take different measures to improve the life and nursing quality of hospitalized patients.

Patients in intensive care unit were more critically ill, and often accompanied by dottiness and restless. In order to avoid the adverse events and self-injury, body constraints were often used on the patients. Therefore, this paper would discuss the ethics of body constraints and give the suggestions. According to the literature review and the analysis of the clinical nursing experience of relevant ethical principles, data was collected. The principle of informed consent, respect, and harmless was hard to decide on the issue of body constraints for patients in ICU. Nurses might pay attention to the application of ethical principles, and strengthen the humanistic care. On the issue of body constraints for ICU patients, nurses might pay special attention to the application of possible ethics principles in nursing process and reduce the application of the body constraints, and promote the physical and mental comfort of patients. It reflected the progress of the humanistic solicitude in the current clinical nursing and important value.

Objective To investigate the effects of Modified Siwutang aqueous extract (mSWT) on bone marrow cell mobilization and plantation in mice after acute myocardial infarction (AMI).Methods The AMI model was established by ligating the left anterior descending artery in Kunming mice.Bone marrow cells were marked by injection of DAPI into the cavitas medullaris of shin bones.Mice were administered with mSWT 60 mg/kg by intragastric administration once a day after surgery.After haematoxylin-eosin and immunofluorescent staining,the plantation of bone marrow cells in AMI area and microvessel density were detected by histopathological assay.The EPCs proportion of peripheral blood was measured by flow cytometry.Results Compared with model mice,infarct size obviously was decreased after mSWT 60 mg/kg treatment,with EPCs ratio increased significantly.Inflammatory cell infiltration of myocardium was much less.Myocardium cellular degeneration and necrosis,fibrosis were reduced,which survival cardiac muscle tissue was increased.DAPI positive cells of plantation and survive were found in AMI region of mSWT group.The number of positive cells were increased in mSWT group than that of model group.There were lot of microvessels of vWF positive expresseion in mSWT than model group.Conclusion:mSWT significantly improved histopathology of AMI mice.The mechanism may be involved in moved bone marrow cells,homed to AMI area and promote angiogenesis.

Aim To investigate the effects of total gin-senosides ( TG) on microvascular regeneration and car-diac function in rat after acute myocardial infarction ( AMI ) . Methods The acute myocardial infarction model was created with left coronary artery ligated in male Sprague Dawley rats. The model rats were ran-domly divided into sham, model, TG low and high dose groups. TG groups were injected into abdominal cavity with TG(20 mg·kg-1·d-1, 40 mg·kg-1· d-1 ) . Sham and model groups were injected with e-qual-volume normal saline. On the 35th day post-opera-tion, heart function was examined by color doppler ul-trasoundination. HE, Masson and immunohistochemis-trical staining were used to observe the histopathologi-cal changes of myocardium and micro vessel density. The level of vascular endothelial growth factor( VEGF) and basic fibroblast growth factor( bFGF) mRNA were detected by real-time PCR. Results Compared with the model group, high and low dose TG obviously de-creased the left ventricular end diastolic dimension, the left ventricular end-systolic dimension, the left ventric-ular end-diastolic volume and the left ventricular end-systolic volume(P<0. 05 and P<0. 01), and signifi-cantly increased the ejection fraction and the fractional shortening ( P <0. 01 ) . The histopathological changes of myocardium on myocardial infarction and fibrosis were dramatically reduced by TG. But ventricular wall was thicker. Two dose TG remarkably increased the expressions of VEGF and bFGF mRNA and micro ves-sel density of compositive CD31 + cells in ischemic myocardial tissue and around of infarct area(P<0. 01, P <0 . 0 5 ) . Conclusions TG could improve the car-diac function of acute myocardial infarction rat. The mechanism may be related to the upregulation of VEGF and bFGF gene expression, the promotion angiogene-sis, then the improvement of blood supply in myocardi-al infarction area.

OBJECTIVE: Insertion of a foreign body in the nasal cavity is a very common incident in children. It is easily diagnosed, but the type of foreign body varies and the extraction can sometimes be difficult with risk of complications. The present study reported nasal foreign bodies diagnosed in emergency in our ENT department, with an update on the state of knowledge. METHOD: A prospective study between Feb 2013 to Sept 2015 included patients admitted to the ENT emergency unit for nasal foreign body. Data comprised age, gender, circumstances of discovery, symptoms, type of foreign body, extraction method and complications. Many patients required anterior rhinoscope for the diagnosis and removal (179/249, 71. 9%), and 170 cases were directly removed and 9 cases were into alimentary canal; Most irregularly shaped objects were removed by a endoscope under general anesthesia (70/249, 28.1%), including button batteries (n= 65), nasal calculi (n = 2) and chopsticks (n = 3). RESULT The main types of foreign body were vegetal forms (61.8%). The incident was discovered following nasal symptoms in 24.9% (n = 62). Extraction was easy by using forceps, micro-hooks or suction in 71.9% of qn:Nasal sinuses foreign body on prevention, detailed history and make the necessary inspection, can improve the correct diagnostic rate.

Objective To explore the early clinical characteristics and influencing factors in children with autism spectrum disorders(ASD).Methods From January 2005 to December 2014,193 children with ASD were collec-ted by continuous grouping method from Children's Rehabilitation Training Center in Xi'an.According to the 1∶1 matched case-control study requirements,and the other 193 children from kindergartens and primary schools in the urban areas of Xi'an were collected as healthy control group from March 1 to July 1,2016.The age of children in the case group was(40.78±14.86)months and the age of the healthy control group was(40.61±14.40)months.There were 167 boys and 26 girls in 2 groups and the ratio of boys to girls was 6.42∶1.00.The general status questionnaires,medical history questionnaire,diagnostic chart,Autism Behavior Checklist(ABC)and Family Environment Scale of Chinese version(FES-CV)were completed by parents between 2 groups.Childhood Autism Rating Scale(CARS)was completed by doctors in the case group.By using Excel software,the original questionnaires were completed in 2 entries by 2 persons to set up the database.All data were analyzed by SPSS 17.0 statistical software and conditional Logistic regression was used for multivariate analysis.Results Seventy point eight percent(137/193 cases)of children with ASD had been found abnormal under 2 years old or at 2 years old,and 54.9％(106/193 cases)had been diagnosed under 3 years old or at 3 years old.The average delay from the discovery to the diagnosis was 17 months.The initial abnormalities appea-rances were mainly manifested as no response to calling in 153 cases(79.3％),very little active contact with others in 141 cases(73.1％),silent or less use of oral language in 137 cases(71％),avoiding contact with the eyes of others or lack of facial expressions in 121 cases(62.7％).Their signs were easy to be misdiagnosed as mental retardation and language retardation.Children in the case group began to walk alone at the age of 8 months to 3 years old,and only 62.2％(120/193 cases)of them could walk alone at the age of 18 months or before.The age of conscious speech was at 8 months to 4 years and 4 months,and only 39.4％(76/193 cases)of the ASD children could speak at the age of 18 months or before.The total scores of the ABC scale of the case group were(56.520±22.140)scores and the sub-scales and total scores were significantly higher than those of the healthy control group,and the difference was statistically significant(t=16.845,27.390,16.527,26.320,23.371,32.206,all P<0.001).The positive consistent rate of ABC and clinical diagnosis was 56.5％.The total scores of CARS in the case group was(36.4±8.6)scores,and the positive consistent rate of CARS and clinical diagnosis was 78.8％.There was a statistical significance between the 2 groups in parental education,mother's occupation,family history(x2=29.670,44.593,15.439,6.095,all P<0.05),and there were statistical significance in the main caregivers,family harmony and family income(x2=19.006,7.129,109.027,all P<0.05).There was no statistical significance between the 2 dimensions of independence and achievement orientation between the 2 groups(t=-1.559,-0.139,P=0.120,0.890).The case group in the family cohesion,expressiveness,intellectual-cultural orientation,active-recreational orientation,moral-religious emphasis,organization and control of the 7 dimension scores were significantly lower than those in the healthy control group,and the differences were statistically significant(t=-7.683,-5.734,-8.762,-14.109,-2.026,-4.530,-2.464,all P<0.05).In the case group,the scores of the conflict dimension were higher than those of the healthy control group,and the difference was statistically significant(t=4.925,P<0.001).There was a statistical significance between the 2 groups in gestational age and birth hypoxia(x2=6.898,27.180,all P<0.05).According to multivariate analysis of Logistic regression,people other than parents serving as the primary support,anoxia of newborn,mother of non professional and technical personnel and lower scores of family active-recreational orientation might be the risk factors of ASD,family per capita income of 3 000 Yuan RMB or more monthly,mother education level of high school and above,and lower scores of family conflict might be the protective factors for ASD.Conclusions Clinical features of most ASD children can be easily identified under 2 years old,but if the diagnosis is delayed,the related intervention is late,so importance should be attached to early diagnosis.Mother's occupation and education level,family economic status,family environment,their supervisors,and anoxia of newborn may be the effective entry points in the prevention and treatment of ASD.

Objective To systematically evaluate the efficacy of high-flow nasal cannulae oxygen (HFNC) in patients with respiratory failure.Methods Computerized PubMed, Embase, Web of Science, the Cochrane Library, CNKI, CBM, VIP, Wanfang Database up to March 31st, 2017, all published available randomized controlled trials (RCTs) or cohort studies about HFNC therapy for patients with respiratory failure were searched. The control group was treated with face mask oxygen therapy (FM) or non-invasive positive pressure ventilation (NIPPV), while the experimental group was treated with HFNC. The main outcomemeasurements included endotracheal intubation rate, patient comfort, and the secondary outcome was in-hospital mortality. The quality of the literature was completed by two professionally trained evidence-based medical students, and meta-analysis was performed on quality-compliant literature. Funnel plot was used to analyze the publication bias.Results A total of 17 articles were enrolled including 15 RCTs and 2 cohort studies. There were 3909 patients enrolled, 1907 patients in HFNC group, and 2002 in control group (1068 patients with FM, and 934 with NIPPV). Meta-analysis showed that HFNC had a significant advantage over FM in reducing the tracheal intubation rate of patients with respiratory failure [odds ratio (OR) = 0.51, 95% confidence interval (95%CI) = 0.29-0.89,P = 0.02], but there was no significant difference as compared with that of NIPPV (OR = 0.80, 95%CI = 0.54-1.17,P = 0.25). It was shown by pooled analysis of two subgroups that compared with FM/NIPPV, HFNC had a significant advantage in reducing tracheal intubation rate in patients with respiratory failure (pooledOR = 0.66, 95%CI = 0.47-0.94, P = 0.02). Compared with FM, patients with respiratory failure were more likely to receive HFNC for comfort [standardized mean difference (SMD) = -0.41, 95%CI = -0.56 to -0.26,P < 0.00001]. There was no significant difference in hospital mortality between HFNC and FM (OR = 0.82, 95%CI = 0.55-1.24,P = 0.35) or NIPPV (OR = 0.66, 95%CI = 0.37-1.17, P = 0.16). The results of pooled analysis of two subgroups were still unchanged (pooledOR = 0.75, 95%CI = 0.54-1.05, P = 0.09). It was shown by the funnel analysis that there was a bias in the study of tracheal intubation rate in the literature, while the bias of patient comfort and hospital mortality was low.Conclusions Compared with FM, HFNC could reduce the rate of tracheal intubation in patients with respiratory failure, but no difference was found as compared with NIPPV. Compared with FM, HFNC made patients more comfortable, and it was easier to be accepted and tolerated. However, there was no difference in hospital mortality among FM, NIPPV, and HFNC.

Objective Survey of Guangxi Traditional Chinese Medicine hospital hand hygiene facilities at all levels was made with improvement measures proposed.Methods Hand Hygiene Norms for Medical Workers questionnaires designed by the Ministry of Health was used in a field survey on hand hygiene facilities of 89 TCM hospitals in Guangxi.Results Facilities of the non-hand-touch taps,hand sanitizer and hand disinfectants were found satisfactory at key departments at all TCM hospitals in the region,yet poor performance with the hand drying facilities.Hospitals with such departments with non-hand-touch taps,hand sanitizer and hand disinfectants accounted for 93.3％,100.0％ and 100.0％.Only 41.6％ of the hospitals were found to use dry hand towels as drying facilities.Significant difference was found at various levels of hospitals' hand hygiene facilities.Conclusion The hand hygiene facilities at such hospitals in Guangxi are receiving growing attention,yet further investment is still required for further improvement and compliance of the medical staff in hand hygiene.
