Then it analyzes the features of and the factors affecting a hospitals overall competitiveness and sets forth the evaluation procedure, viz. establishing an evaluation index system, determining and normalizing the standard value for evaluating each index, giving each index a corresponding weight according to its importance and conducting comprehensive evaluation. Next the paper discusses ways of predicting a hospitals overall competitiveness. The steps include: making clear that the purpose of the prediction is to enhance the competitiveness of the hospital in the future, screening the data, selecting the method of prediction, setting up a mathematical prediction model, conducting prediction with the model and evaluating and modifying the evaluation results.

Nitrocellulose membrane based urinary protein preservation method is simple, fast and economic, but its advantage over the traditionally used acetone precipitation method is still unclear. In this work, we prepared urinary proteins by the two methods by LC-MS/MS. Then we used protein spectra counts to assess the reproducibility of the two methods. Proteins identified by the two methods were almost the same in number, spectral count distribution and distribution of coefficients of variation value. In conclusion, nitrocellulose membrane method is generally the same as acetone precipitation method. It can be used for large scale preservation of clinical urine samples.

Objective:To research the application of flurbiprofen compound small dose fentanyl with self-control vein analgesia after laparoscopic cholecystectomy and the influence on blood coagulation function.Methods:102 cases with laparoscopic cholecystectomy who were treated in our hospital from November 2015 to November 2016 were selected and divided into the control group and the research group,with 51 cases in each group.The patients in the control group were treated with postoperative intravenous analgesia with low-dose fentanyl,while the patients in the research group were treated with postoperative intravenous analgesia with flurbiprofen ester compound low-dose fentanyl.Then the fibrinogen (Fg),activated partial prothrombin time (APTT),prothrombin time (PT),platelet count (PLT),substance P,5-hydrocarbon serotonin (5-HT),interleukin 6,8 (IL-6,IL-8) and complications between two groups were observed and compared.Results:Before treatment,there was no statistically significant difference about the Fg,APTT,PT,PLT,substance P,5-HT,IL-6 and IL-8 between two groups (P＞0.05);After treatment,the Fg,APTT,PT,PLT,substance P,5-HT,IL-6 and IL-8 increased in the two groups,while the research group was lower than that of the control group,and the differences were statistically significant (P＜0.05).The postoperative complication rate of research group was lower than that of the control group (P＜0.05).Conclusion:Flurbiprofen ester compound small dose fentanyl with self-control vein analgesia can relieve coagulation function,and inhibit the levels of inflammatory factors.

[ ABSTRACT] AIM:To explore the regulatory effect of intermedin ( IMD) on pulmonary collagen synthesis and ac-cumulation in rats with pulmonary hypertension induced by high pulmonary blood flow.METHODS: Healthy male SD rats (n=20) were randomly divided into control group (n=7), shunt group (n=7) and shunt with IMD group (n=6).The shunting of abdominal aorta and inferior vena cava was produced in rats of shunt group and shunt with IMD group.After 8 weeks, IMD was administered into the rats of shunt with IMD group subcutaneously by mini-osmotic pump for 2 weeks.Mean pulmonary artery pressure (mPAP), relative medial thickness (RMT) of pulmonary arteries, contents of hydroxyproline, collagen type I and III, bone morphogenetic protein-2 (BMP-2), and the mRNA expression of procollagen I and III in lung tissues were measured and compared.RESULTS:Compared with control group, mPAP and RMT of medium and small pul-monary arteries in the rats of shunt group were significantly increased.Meanwhile, the lung hydroxyproline, collagens I and III and BMP-2 contents, and the mRNA expression of lung procollagen I and III were all significantly increased compared with control group.However, IMD significantly decreased mPAP, alleviated the changes of pulmonary vascular micro-struc-ture, decreased the collagen accumulation and pulmonary tissue homogenate BMP-2 contents, and inhibited the mRNA ex-pression of procollagen I and III in the lung tissue of shunting rats.CONCLUSION:IMD plays a protective role in the de-velopment of pulmonary hypertension and pulmonary vascular structural remodeling induced by high blood flow by inhibiting pulmonary collagen synthesis and accumulation, possibly in association with the BMP-2 pathway.

Objective To study the antitumor activity of steroid saponins,such as Rhizoma Paridis saponins,Rhizoma Paridis saponin Ⅰ,and diosgenin,extracted from Paris polyphylla var.yunnanensis against lung adenocarcinoma cells.Methods Taking mouse lung adenocarcinoma LA795 cell line and its T739-bearing mice as models,the antitumor activity of steroid saponins of P.polyphylla var.yunnanensis against lung adenocarcinoma cells was carried out in vitro and in vivo.The inhibitory activity of Rhizoma Paridis saponins,Rhizoma Paridis saponin Ⅰ,and diosgenin on the LA795 cell line was studied by means of MTT assay and their antitumor effects in vivo were carried on inbred strains of mice(T739) affected by LA795 metastatic lung cancer.Results The MTT assay of in vitro cytotoxicity of Rhizoma Paridis saponins,Rhizoma Paridis saponin Ⅰ,and diosgenin showed strong cytotoxicity against the growth of LA795 cells.IC50 Values were 24.33 ?g/mL,1.85,and 149.75 ?mol/L,respectively.The tumor weight in all treated groups was significantly lower than that in the control group and the inhibition of tumor growth were 41.82%,29.44%,and 33.94% in their high-dose groups.The metastasis of tumor cells was inhibited by different degrees in treated groups.Conclusion Steroid saponins of P.polyphylla var.yunnanensis have tumoricidal activity on lung adenocarcinoma cell line,both in vitro and in vivo.

Objective To explore the feasibility of coelocentesis in prenatal diagnosis.Methods Coelocentesis were applied on 58 women scheduled for at 6～12 weeks of gestation,and fetal heart rate before the procedure and 1,5,30 minutes afterwards and hemorrhage of amnionic cyst was observed.Y gene of sex-determining region was detected by polymerase chain reaction,and compared with chorionic villi sample.Results The total achievement ratio of coelocentesis was 96.6% of all cases in five minutes.The coelomic fluid was successfully aspirated at first attempt in 93.2% at 7～10 week's gestation,25.0% at 6～7weeks and 50.0% at 10 ~ 12 weeks.There was no significant difference in FHR between before coelocentesis and afterwards (P＞0.05).The detection accurate rate of SRY was 91.1%,all female fetus were matched with those observation by chorionic villi sampling,and only 5 male fetus were not matched,the accurate rate was 80.8%.Conclusion Coclocentesis has the advantage of simple procedure,safe and high feasibility.The optimal time of coclocentesis is in the 7th to 10th week of gestation.

To compare two enrichment and preservation methods of urinary proteins, stored in polyvinylidene difluoride (PVDF) membrane (Urimem) or direct freezing, we examined the differences between the two methods in time, space, costs of supplies and electricity, degree of protein degradation and convenience of the sample handling. The urimem method is superior in the storage space, the cost of electricity and the clinical convenience compared to the direct freezing method. However, the direct freezing method is superior in the time and the cost of supplies to the urimem method. The enrichment and preservation of urinary proteins using urimem have more cost-effective benefits compared to those of the direct freezing method.

AIM:To investigate the effect of quercetin on the biological functions of rat bone marrow-derived endothelial progenitor cells (EPCs) and its potential mechanisms.METHODS:The bone marrow-derived mononuclear cells of Sprague-Dawley rats were isolated by density gradient centrifugation.The differentiated EPCs were cultured specially and stained with DiI-Ac-LDL and FITC-UEA-1.CD133+ and FLK-1+ were detected on the cell surfaces.After 14 d, the EPCs were incubated with a PI3K inhibitor BYL719 (3 μmol/L) and an ERK inhibitor FR180204 (15 μmol/L).After incubation of the inhibitors for 2 h, the cells were treated with quercetin at different concentrations (0, 10, 20, 40, 80 and 100 μmol/L).MTT assay and Transwell assay were used to detect cell viability and the number of migratory cells.The protein levels of AKT, eNOS, ERK and their phosphorylated status were determined by Western blot.RESULTS:Quercetin enhanced the viability and migration of the EPCs at a dose-dependent manner.However, the PI3K inhibitor BYL719 suppressed the QUE-induced cell viability and migration.Moreover, ERK inhibitor FR180204 exerted the similar inhibitory effect on the cell viability but had no effect on cell migration.Quercetin activated the phosphorylation of AKT, eNOS and ERK.On the other hand, BYL719 was observed to inhibit the phosphorylation of AKT and ERK.FR180204, however, was showed to inhibit the phosphorylation of ERK only.On the contrast, the stimulatory effects that quercetin exerted on the expression of eNOS and its phosphorylation were suppressed by BYL719 and FR180204.CONCLUSION:Quercetin stimulates the viability and migration of EPCs via PI3K/AKT/eNOS and ERK/eNOS signaling pathway, which would be beneficial for cardiovascular health.

Objective To observe the changes and clinical significance of procalcitonin(PCT) level in children with bacterial pneumonia.Methods The levels of PCT,hs-CRP and WBC were detected in 31 pneumonia children pre and post antibiotic treatment,and the changes were observed.Results The PCT levels of the 31 patients were all increased before treatment.After cured,PCT level of 28 cases returned to normal.But in the 28 normal cases,WBC level increased in 10 cases(35.7％),and hs-CRP level elevated in 4 cases(14.3％).In the other 3 cases,the PCT levels decreased from 5.69ng/mL,1.25ng/mL and 0.83ng/mL at admission to 0.51ng/mL,0.55ng/mL and 0.52ng/mL,respectively.And in these 3 cases,there was one case with the levels of WBC and hs-CRP respectively ascended,in which WBC level descended from 13.1 × 109/L to 12.1 × 109/L and hs-CRP level reduced from 20.92mg/L to 7.38mg/L.Conclusion The sensitivity of the index PCT is the highest at the accurate time phase of bacterial pneumonia,which can guide the reasonable use of antibiotics.
