Objective To investigate the prevalence of nutritional risk and nutrition support treatment in elderly hospitalized patients,and provide a basis for nutrient management in elderly hospitalized patients.Methods The Nutritional Risk Screening 2002 (NRS 2002) were administered to 163 patients (74 cases in digestive system and 89 cases in endocrine system) in elderly hospitalized patients from November 2013 to March 2014.Results The prevalence of nutritional risk was higher than in the digestive system (60.8％) in the endocrine system (32.6％) (P＜0.05).Conclusions There is a high prevalence of nutritional risk in elderly wards,and the wards with lower prevalence of nutritional risk are more likely to lack of nutrition support treatment.Therefore,it is necessary to pay attention to nutritional risk and nutritional support treatment in departments with low prevalence of nutritional risk.

OBJECTIVEThis study aims to evaluate the influence of different bone types on the stress distribution in tooth implant-supported fixed partial prostheses by using finite element (FE) analysis.

METHODSFour FE models of mandibular arch containing one implant splinted to the mandibular second premolar were built according to bone types I, II, III, and IV. Dynamic loads of 250 N were applied to the buccal and lingual cusps of the prostheses in different directions to simulate the masticatory cycle. The maximum Von Mises stresses were calculated using the FE analysis software.

RESULTSThe maximum Von Mises stresses of the cortical bones were 89.229, 91.860, 125.840, and 158.420 MPa, increasing from type I to type IV, respectively. The maximum Von Mises stresses of the trabecular bone were 58.584, 43.645, 21.688, and 18.249 MPa, decreasing from type I to type IV, respectively. During the process of dynamic loading, the maximum Von Mises stresses of the cortical and trabecular bones followed the order buccal to tongue loading>tongue to buccal loading>vertical loading.

CONCLUSIONThe results showed that bone type significantly influenced the stress distribution in bones, and that for tooth implant-supported fixed partial prostheses, bone types I and II were a better choice than bone types III and IV. More caution should be exercised when restoring missing teeth using tooth implant-supported fixed partial prostheses in softer bone regions.

ObjectiveTo investigate mutations in exons 19, 20 and 21 of epidermal growth factor receptor (EGFR) gene in elderly patients with non-small cell lung cancer (NSCLC). MethodsEGFR gene mutations in exons 19, 20 and 21 were detected by nested PCR amplification and DNA sequencing in 46 elderly patients with non-small cell lung cancer. The relationship between mutations and clinical characteristics of these patients was analyzed. ResultsEGFR gene mutations were found in 56.5% (26/46) patients and 41.3% (19/46)were non-silent mutations. Mutation of exon 19 was detected in 6 cases (13.0%), mutation of exon 20 in 13 cases(28.2%) and that of exon 21 in 14 cases (30.4%). Seven patients among them had double mutations and the rest only had a single mutation. The incidence of EGFR gene mutations was higher in non-smokers than in smokers(P＜ 0.01). Higher EGFR mutation rate in exon 19, 20 and 21 were found in patients with clinical benefit who were treated with tyrosine kinase inhibitor(TKl)(P＜0.05). There was no difference in EGFR mutation rate between 60～69 age group and 70～85 age group. ConclusionsThe data suggest that the characteristics of EGFR gene mutations in elderly patients with NSCLC is the same as in the general NSCLC patients. The forecast informations of TKI treatment can be obtained by gene detection in elderly NSCLC patients.

Objective To explore the relationship between body composition and arterial function index,especially augmentation index(AI),and make clear the impacts of gender and age on the relationship.Methotis A total of 3859 health adults were enrolled in this study.Boay composition was measured by bioelectrical impedance,and AI and pulse wave velocity(PWV) were viewed as indictors for arterial function.Correlation analysis and liner regression analysis were used for data comparison.Results Both body mass index(BMI) and body fat rate positively changed with PWV(r=0.114,both P<0.01).However,BMI showed no relation to AI(r=0.022,P>0.05).Body fat rate was positively and independently associated with AI(r=0.263, P<0.01),which was gender-dependent(female:r=0.219,P<0.01;male:r=0.033,P>0.05).When age was concerned,above relationship was more stronger in participants ≤50 years(β=0.479 vs β=0.321,P<0.01).Conclusion Body fat mass may be a predicting factor of changes in AI.Gender and age could affect the relationship between body fat and rtery function.

We investigated and analyzed the first case of human infection with avian influenza A(H9N2) virus in Yunnan Province,China,so as to provide a better basis for preventing and controlling human infections with viruses of animal origin in the future.We carried out the field epidemiological survey among the patient,close contacts and the live poultry markets,detected and analyzed the samples from patient and the outdoor environment.Results showed that the 9-month-old boy was a case of human infection with avian influenza A(H9N2) virus with the history of live poultry markets exposure and the results of nucleic acid detection and virus isolation.There was a lot of contamination of the avian influenza virus in the live poultry markets.The second generation cases have not occurred.The monitoring of pneumonia of unknown etiology and influenza like cases in medical institutions is the important means to find timely cases of human infected with avian influenza.Regular disinfection and closing-down of live poultry markets are key measures to reduce the exposure opportunity.

Objective To learn the cognitive status for newborns medical pain in medical workers of neonatal intensive care unit of children′s hospitals and provide clinical basis for optimizing neonatal pain management. Methods Totally 320 medical staff in neonatal intensive care units of six children′s hospital in Wuhan, Shenzhen, Shanghai, Nanjing, Zhejiang, Chongqing were investigated using medical pain management survey questionnaires by means of convenience sampling method. Results The knowledge on neonatal pain were at quite high level, accuracy rate was (80.5 ± 18.1)%;but on pain feel, pain relief rate and anodyne-use, the accuracy rate was relatively low; chest drainage, lumbar puncture and PICC placement were generally considered to cause severe pain with scores of 8.03±2.20, 7.17±2.17, 7.09 ± 2.00, respectively. Medical staff with different degrees, having children or not, different titles and with different years of working at NICU had impact on neonatal pain assessment on heel prick and venipuncture among full-term newborns. The difference was statistically significant (χ2=6.208-23.314, P<0.05). Conclusions Neonatal pain management is gradually emphasized by clinical medical staff, but there exist a certain bias on the perception and assessment of pain. So, it needs to strengthen pain-related knowledge training on health care for newborns to prevent and reduce neonatal pain, improving neonatal pain management.

Objective To investigate the outcomes of patients undergoing off-pump coronary artery bypass grafting (OPCABG) under morphine-fentanyl combined anesthesia. MethodsSeventy-two patients aged 41-64 yr undergoing OPCABG were randomly divided into 2 groups (n = 36 each): Ⅰ group morphine + fentanyl (group MF) and Ⅱ group fentanyl (group F). Anesthesia was induced with midazolam, etomidate, and vecuronium.Fentanyl 10-20 μg/kg was given iv when needed. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintsined with inhalation of 0.5%-2.0% isoflurane and intermittent iv boluses of vecuronium in both groups. Morphine 0.15 mg·kg-1·h-1 + fentanyl 8 μg·kg-1·h-1 were infused during operation in group MF, while in group F fentanyl 10 μg·kg-1·h-1 was infused. Morphine 0.75 mg/h was infused in group MF or fentanyl 10 μg/h in group F for postoperative analgesia after extubation. Recovery from anesthesia was assessed using a nine point (QoR) questionnaire. Pain was measured with VAS score and sedation with Ramsay sedation score ( 1 = fully awake, 6 = asleep, no response to verbal stimulus). The postoperative complications were recorded. ResultsQoR scores were significantly higher in group MF and in group F. The incidence of postoperative febrile reaction was significantly reduced in group MF. There was no significant difference in Ramsay sedation score and other postoperative complications between the 2 groups. ConclusionMorphine-fentanyl combined anesthesia is more beneficial for the prognosis in patients undergoing OPCABG compared with fentanyl combined anesthesia.

Objective:In order to provide policy-makers with basis and reference for improving the operational efficiency of county general public hospitals, this paper studies the changes in overall efficiency, technical efficiency and scale efficiency of 40 county general public hospitals in Fujian province from 2009 to 2014 , as well as how the to-tal factor productivity changes over the time. Methods: After collecting the relevant data of hospital operations from 2009 to 2014, this paper uses CCR, BBC, Malmquist model and other data envelopment analysis (DEA) methods to analyze the data. Results:The vast majority of those 40 county general public hospitals are in decreasing state. The total factor productivity of 40 hospitals from 2009 to 2014 is 1. 019. There are 21 hospitals (52. 5%) that slightly im-proved their productivity, of which 3 hospitals increased their productivity mainly due to technological progress, 3 hospitals due to efficiency increase, and the rest 15 hospitals due to the effect of both technological progress and effi-ciency increase. Conclusions:The operational efficiency of county general public hospitals in Fujian province is gen-erally insufficient, and there are significant differences between operating efficiency of different regions. The efficien-cy of hospitals in mountainous areas had increased, but the efficiency of hospitals in coastal areas had decreased. Therefore, in order to increase investment in county general public hospitals, the government should take differential policy and pay attention to the reasonable control of hospital size, as well as to strengthen the connotation building and attach importance to improving medical service technologies.
