The traditional approach to accessing healthcare information restricts the further development of healthcare services,thus unable to meet the growing needs of individual healthcare.The flexible sensor technology has emerged along with the development of new materials,machinery and manufacturing technology.As a result,textiles,accessories,human skin and even internal body organs can be integrated with various sensors.The popularization of flexible sensors provides new methods for monitoring health,improving therapeutics,investigating disease status and building the human-machine in-terface.Through a systematic investigation of literature,this paper reviews the applications of flexible sensors in health-care,discusses the key technologies,and introduces the common materials and manufacturing technology.

This paper is aimed to assess the effects of red blood cell (RBC) transfusion on clinical outcomes in cardiac surgery. Trials were identified by computer searches of the Pubmed, MEDLINE, Cochrane Library (Issue 10, 2012), from January 1980 to October 2012. References in identified trials and review articles were checked and experts contacted to identify any additional trials. The homogeneous randomized controlled trials (RCTs) were analyzed with RevMan 5.1 software. Five trials involving a total of 1,203 patients were identified. The results of meta-analyses showed that restrictive transfusion strategies reduced the risk of receiving a RBC transfusion (MD = - 1.46, 95% CI -1.18(-) -1.1) and the volume of RBCs transfusion (RR = 0.69, 95% CI 0.53-0.89). No significant difference was noted between the two strategies in terms of mortality, adverse events and hospital or intensive care length of stay. Based on the results mentioned above, one can draw a conclusion that restrictive transfusion strategies reduced the risk of receiving RBC transfusion and the volume of RBCs transfused. Restrictive transfusion strategies did not appear to impact on the rate of adverse events and hospital or intensive care length of stay, compared to liberal transfusion strategies.

Objective To investigate the effect of venlafaxine on learning and memory ability in rats with vascular dementia(VD).Methods Totally 90 Wistar rats were divided into sham-operation group,model group and treatment group (n=30 for each).The VD rat model was established by modified pulsinellis 4-vessel occlusion (4 VO).Rats in the sham-operation group and model group were administered with gastric perfusion of distilled water.Rats in the treatment group were administrated with gastric perfusion of Venlafaxine at 15 mg/kg per day for 4 weeks from the 2nd day after the modeling.The one-way avoidance test was performed to study the learning-memory ability of each group.The contents of norepinephrine,5-hydroxytryptamine and BDNF in the hippocampus and cortex of rats were observed.Results Model group demonstrated a decrease in the percentage of one-way avoidance test (50.3±6.2 vs.92.3±5.6,P＜0.01) as compared with sham-operation group,and this value was increased in treatment group (62 2±4.6).Compared with the sham-operation group,the contents of NE and 5-HT in the hippocampus [(226±34) pg/g and (340±40) pg/g],and cortex [(601±66) pg/g and (657±43) pg/g] in rat brains of model group were decreased (P＜0.01),while increased in treatment group [(264±45) pg/g and (379±42)pg/g,(665±68) pg/g and (798±51)pg/g,P＜0.05].The OD value of BDNF in the hippocampus (0.495±0.041) and cortex (0.488±0.042) were increased (P＜0.05) in model group,and in treatment group,BDNF levels were more higher (0.579±0.044 and 0.578±0.06/4,P＜0.05).Conclusions The content of brain monoamine neurotransmitters are decreased in rats with VD,while venlafaxine can improve the learning memory ability in model rats through increasing the levels of 5-HT,NE and BDNF in hippocampus and cortex.

Objective To discuss CT examination in the diagnosis of gastrointestinal perforation (GP). Methods All CT data of 13 adult patients with GP were reviewed retrospectively. Results In all 13 cases,gastric perforation occurred in 5 cases,duodenal perforation in 7,and traumatic duodenal avulsion in 1.CT findings of GP included gas accumulation under the recess of xiphoid,gas accumulation in the area of lesser omentum,gas accumulation under the recess of peritoneal cavity,and seroperitoneum. Conclusion As a non-invasive examination means for abdomen,CT examination can discover whether there is dissociative gas or not and estimate the amount of gas in abdomen more rapidly and exactly.CT can also estimate the position of perforation elementarily.The recess under xiphoid is the first place where the dissociative gas assembles after gastrointestinal perforation.

Objective To investigate the effects of constant magnetic field (CMF) on proliferation, apopto-sis and nitric oxide (NO) secretion of rat bone marrow-derived endothelial progenitor cells (EPCs) intervened by C-reactive protein (CRP). Methods EPCs were isolated from rat bone marrow by density gradient centrifugation and cultured on fibronectin-coated dishes. The cells were divided into five groups, i. e., control group, CRP (12 μg/ml) group, CRP plus CMF (0.1, 0. 5, 1.0 mT) groups. Samples were collected 24 hours after incubation. Cell proliferation was measured by MTT chromatometry. Apoptosis rate was detected by flow-cytometry. NO content of culture medium was measured by nitrate reductase method. Results As compared with control group, cell prolifer-ation in CRP group reduced significantly (0. 265±0. 008 vs 0. 316±0. 011, P < 0.05), NO secretion also de-creased significantly [(22.7±4.5) μmol/L vs (37.6±3.8) μmol/L, P < 0.05], cell apoptosis rate elevated sig-nificantly [(10.8±0. 8) % vs (4.2±0.5)% ,P < 0.05]. Cell proliferation in CRP plus 0. 5 mT or 1.0 mT CMF group (0. 295±0. 009,0. 302±0. 010) were much more than those in CRP group (P<0.05), NO secretion contents [(28.3±4.9) μmol/L, (29.2±5.6) μmol/L]were also much more than those in CRP group (P < 0.05) , apopto-sis rate [(7.4±0.5)% ,(6.9±0.6)%]was significantly lower than that in CRP group (P <0.05). Conclusion CMF at intensity of 0.5 mT and 1.0 mT can antagonize the effects of CR, promote proliferation of EPCs and secretion of NO and inhibit apoptosis rate of EPCs.

Objective To understand the relationship between the dietary patterns and metabolic syndrome among elderly people in Zhejiang province,in order to provide scientific basis and reference for nutrition interventions.Methods Data were obtained from the 2010-2012 Chinese National Nutrition and Health Survey,and factor analysis was used to obtain food patterns among elderly people in Zhejiang province.The Logistic regression was used to explore the association of the food patterns with metabolic syndrome and its components.Results The intakes of bean products,nuts,fruits,eggs,and milk in elderly people were generally low,and the intakes of livestock and poultry meat,cooking oil and salt were relatively high.5 dietary patterns were derived by factor analysis:high-quality protein diet,mediterranean diet,condiments diet,traditional dietary pattern and western dietary pattern.The medical test results in 780 elderly people showed that the standardized prevalence of metabolic syndrome in the elderly was 28.8％,standardized central obesity rate was 41.2％,standardized hypertension rate was 50.3％ and standardized hyperglycemia rate was 39.5％.Logistic regression analysis showed that different dietary patterns had different effects on the metabolic syndrome and its components.Conclusions The prevalence rate of metabolic syndrome and the abnormal rates of its components are high in the elderly in Zhejiang.The intakes of fruits and milk are generally low,and intakes of livestock and poultry meat,cooking oil and salt are relatively high.The relationship between dietary patterns and MS or its components is complicated,so it is necessary to guide the elderly people to adopt reasonable diet by referring to the Diet Pagoda in order to reduce the risk of MS or its components.

This article was aimed to study the effect of polyphenols fromRubus suavissirnusS. Lee (RSLP) on spontaneous hypertensive rats (SHR) and to explore its mechanism of anti-hypertensive. The water extraction of RSLP was prepared. And the polyphenols was extracted with macroporous resin. The non-invasive blood pressure analysis system was used to detect the blood pressure. SHR model was selected to study the anti-hypertensive effect. The 16 normal Wistar rats were randomly divided into the control group and the normal RSLP high-dose group (RSLP-NH). The 40 SHR were randomly divided into the model group, Captopril group, RSLP-L group, RSLP-M group and RSLP-H group. SBP, DBP, HR, body weight and organ index were observed after the drug administration for 8 weeks and drug withdrawal for 2 weeks. The contents of SOD, MDA, GSH-Px, NO, NOS and ANP in serum were measured. The results showed that the blood pressure of SHR was significantly higher than that of the control group, which can be used for anti-hypertensive studies. Each RSLP group can obviously reduce the SBP and DBP of SHR (P < 0.05), but it had no effect on HR (P > 0.05). RSLP can elevate GSH-Px, SOD levels and reduce the activity of MDA (P < 0.05). RSLP can reduce NO, NOS and ANP contents in serum (P < 0.05). It was concluded that RSLP can significantly reduce the SBP and DBP of SHR, but it had no significant effect on HR. It can increase the activity of GSH-Px, SOD, NO, NOS levels, and reduce the contents of MDA, ANP in serum. It had certain inhibitory effect on the left ventricular hypertrophy.

Objective To discuss the expression and significance of neutrophil to lymphocyte ratio(NLR) and platelet to lymphocyte ratio(PLR) in peripheral blood in patients with chronic obstructive pulmonary disease(COPD).Methods One hundred and fifty cases COPD patients who were treated in Respiratory Departments of Hai'an People′s Hospital Affiliated to Nantong University from January to December 2015 were selected and divided into stable period group with 60 cases and acute exacerbation period group with 90 cases,and 50 healthy subjects were selected as control group.Clinical data were collected and white blood cell count(WBC),neutrophil count(NC),lymphocyte count(LC),platelet(PLT),NLR,PLR,forced expiratory volume in one second(FEV1%) predicted and C reactive protein(CRP) were tested.Results NLR,PLR and CRP values were significantly higher in patients in acute exacerbation period group than in stable period group and control group(NLR:(10.30±9.93) vs.(6.76±5.90) vs.(5.85±3.67);PLR:(335.88±164.94) vs.(286.80±118.98) vs.(194.11±88.14);CRP: (42.18±24.89) mg/L vs.(23.27±13.59) mg/L vs.(22.49±13.47) mg/L,F=6.637,6.808,11.007,P<0.05),but FEV1% predicted was no difference in stable period group and acute exacerbation period group((58.85±16.83)% vs.(57.47±17.76)%;t=0.228,P>0.05).There was a significant positive correlation between NLR,PLR and CRP in acute exacerbation period group(r=0.374,0.379,P<0.01),there was a positive correlation between NLR and PLR(r=0.482,P<0.01),there was a negative correlation between NLR,PLR and FEV1(r=-0.297,-0.299,P<0.05).There was a significant positive correlation between NLR,PLR and CRP in table period group(r=0.593,0.433,P<0.01),NLR and PLR were also positively correlated(r=0.618,P<0.01),NLR,PLR and FEV1 accounted for the expected value of the negative correlation(r=-0.324,-0.342,P<0.05).Conclusion Both NLR and PLR are inflammatory markers,furthermore they show a significant negative correlation to airflow limitation in patients with COPD.

Through comparative study on Naotaifang containing serum and plasma proteomics (peptide), this article revealed differential proteins (peptides) in the Naotaifang. The characteristics of differential proteins were identified with mass spectrometry. It provides scientific evidences for the pharmacodynamic material basis and Chinese herbal medicine plasma pharmacological method development in the exploration of Naotaifang. A total of 20 healthy adult SD rats were randomly divided into the control group, Naotaifang treatment group according to their weights. Ten rats in each group. Intragastric administration of medication was given for seven consecutive days. Before surgery, rats were fed with water but without food. One hour after the last drug administration, 10% chloral hydrate was injected for intraperitoneal anesthesia. Blood was taken through the common carotid artery. Serum and plasma samples were made after blood was taken from each rat. Serum and plasma samples of five rats were randomly selected from each group. And the two-dimensional electrophoresis (2-DE) technique was used in the comparative study of serum pro-teomics (peptide). The 300 DPI scanning and PDQuest 7.3.0 were used in the analysis. The ESI-MS/MS was used to identify important differences in proteins and screen characteristic serum and plasma protein. The results showed that 20 differential proteins of 5 plasma samples were identified. There were 15 types of proteins expressing up-regulation and 5 types expressing down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum, 19 differential proteins of 5 plasma samples were identified, among which 15 types of proteins express up-regulation and 4 down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum and Naotaifang containing plasma showed that 24 differential proteins of 5 plasma samples were identified, among which 9 types of proteins express up-regulation and 15 down-regulation. The highly expressed proteins were selected to MALDI-TOF-MS between Naotaifang containing serum and Naotaifang containing plasma. There were six successful-ly identified proteins, which were inter-alpha trypsin inhibitor, heavy chain 3, group-specific component, comple-ment factor B, Receptor Complexed with A Heterodimeric Fc, isoform CRA-d, Transferrin. It was concluded that protein with obvious changes in the Naotaifang containing serum and plasma may be related with fibrinolysis and an-ticoagulant. These proteins are involved in angiogenesis, inflammation and other pathological regulations of physiolog-ical processes. They are of great significance in the study of effective target and its signal transduction pathway of Naotaifang.
