Objective To study the mechanism of lentinum's promotion on carvedilol's effects on dilated cardiomyopathy's heart function.Methods SD rat model of dilated cardiomyopathy was established with doxorubicin hydrochloride.The rat model was divided into blank control group,carvedilol group,lentinan group,carvedilol + lentinan group.Rats in the blank control group were given 2 mL of 0.9％ sodium chloride solution.Rats in the carvedilol group were given 10 mg·kg-1of carvedilol and 2 mL of 0.9％ sodium chloride solution.Rats in the lentinan group were given 1 mg·kg-1 of lentinan,and 2 mL of 0.9％ sodium chloride solution.Rats in the carvedilol + lentinan group were given10 mg· kg-1 of carvedilol,1 rmg·kg-1 of lentinan,and 2 mL of 0.9％ sodium chloride solution.The heart function,irrflammatory factors and T lymphocytes were compared.Results The left ventricular ejection fraction (LVEF) in carvedilol + lentinan group and carvedilol group were significantly higher than that in blank control group and lentinan group (P ＜ 0.05),while Tei index was significantly lower (P ＜ 0.05).The LVEF in carvedilol + lentinan group was significantly higher than that in carvedilol group (P ＜0.05),while Tei index was significantly lower (P ＜0.05).The hs-CRP,TNF-α,II-6 and IL-8 in carvedilol + lentinan group and lentinan group were significantly lower than that in blank control group and carvedilol group (P ＜0.05),while IL-10,CD3+,CD4+ and CD8+ were significantly higher (P ＜ 0.05).The hs-CRP,TNF-α,II-6 and IL-8 in C + L group were significantly lower than in lentinan group (P ＜ 0.05),while IL-10,CD3+,CD4+ and CD8+ were significantly higher (P ＜ 0.05).Conclusion Lentinan could significantly promote carvedilol's effects on dilated cardiomyopathy's heart function through lowering down inflammatory factors and increasing T lymphocytes.

Objective To explore the relationship between organizational justice and turnover intention among nurses of tertiary hospitals and to provide implications for human resource management.Methods Totally 511 nurses were recruited from four tertiary hospitals of Jinan City and investigated with Organizational Justice Questionnaire and Turnover Intention Scale.Results The average scores of turnover intention and organizational justice were (2.46±0.61) and (3.55±0.62),respectively.Distributive justice and informational justice were significant predictors of turnover intention.Conclusions The turnover intention of nurses in tertiary hospitals is high.It is beneficial for mitigating nurses' tumover intention to improve their organizational justice,apply post management and performance appraisal model.

Objective To systematically evaluate the effectiveness of diabetes self-management education through telemedicine on glycosylated hemoglobin (HbA1c). Methods Randomized clinical trials (RCTs) that assessed the effectiveness of remote diabetes self-management education in patients with diabetes were systematically reviewed using multiple electronic databases. The searching time was from database establishment to May 2015. These articles were analyzed after evaluation of their quality. Results Eight RCTs were included involving 2 047 patients.The results of Meta-analysis showed the effectiveness of remote DMSE on reduction of HbA1c of patients with type 2 diabetes was more significant than that of the control group [WMD=-0.50,95%CI (-0.88,-0.12),P < 0.05],while failing to support the effectiveness of remote DMSE on patients with type 1 diabetes [WMD=0.62, 95%CI(-0.19,1.43), P>0.05]. Conclusions Remote DMSE is effective to improve the glycemic control in patients with type 2 diabetes,while the effect on patients with type 1 diabetes is still not certain. Large-scale and multi-centered RCTs are needed to confirm its effectiveness.

Objective To know the correlation of anxiety and pains of out-patients who had accept-ed operation and the effect of nursing intervention. Methods Divided 173 out-patients with operation in-to the intervention group(83 cases) and the control group(90 cases) randomly. Routine nursing cares was used in the control group, preoperative health education was used in the intervention group in addition. Us-ing the Me-Gill and SF-MPQ to evaluate pains between the 2 groups. Using the S-AI and the T-AI to evaluate the emotional condition between the 2 groups. Results The indexes which can indicated the pains and emotional condition in the intervention group after the health education were significant better than those of in the control group and themselves before the nursing intervention. Conclusions Preoperative pains and emotional condition should be evaluated among out-patients, and then carry out certain counter nursing measures to release patients' pain and negative emotion.

Objective To compare the laboratory and clinical results between unstimulated in vitro maturation (IVM) and IVM converted from in vitro fertilization (IVF) in polycystic ovarian syndrome (PCOS) and non-PCOS patients.Methods We divided 591 IVM cycles in the First Affiliated Hospital of Wenzhou Medical Univesity from Jan.2008 to Dec.2013 into 4 groups:group A1B1,PCOS patients underwent unstimulated IVM protocol,240 cycles; group A1B2,PCOS patients underwent IVM converted from conventional stimulated IVF protocol,153 cycles; group A2B1,non-PCOS patients underwent unstimutlated IVM protocol,103 cycles; group A2B2,non-PCOS patient underwent IVM converted from conventional stimulated IVF protocol,95 cycles.Multiple linear regression method and binary logistic regression method were used to assess the influence of PCOS and protocols for IVM on laboratory and clinical outcomes.Results The mean number of oocytes retrieved was positively related with PCOS [partial regression coefficient (B)=3.37,P＜0.01].The maturation rate of oocytes was positively related with hCG-prime prior to oocyte aspiration (B=0.05,P=0.010).High-quality embryo rate was positively related with PCOS and IVM converted from IVF (B=0.08,P=0.010; B=0.09,P=0.001),as well as implantation rate related with them (B=0.07,P=0.010; B=0.10,P＜0.01).PCOS and IVM converted from IVF improved hCG positive (hCG＞10 U/L) rate (OR=1.636,95％CI:1.113-2.204,P＜0.05; OR=1.861,95％CI:1.307-2.649,P＜0.05) and the clinical pregnancy rate (OR=1.507,95％CI:1.041-2.240,P＜0.05; OR=1.881,95％CI:1.312-2.696,P＜0.05).IVM converted from IVF protocol decreased the spontaneous abortion rate (OR=0.490,95％CI:0.245-0.978,P＜0.05).Multiple gestation rate and ectopic pregnancy rate were not affected by PCOS condition and protocol used (P＞0.05).Conclusions PCOS and IVM converted from IVF protocol improved the high-quality embryo rate,implantation rate,hCG positive rate and clinical pregnancy rate.IVM converted from IVF protocol reduced the spontaneous abortion rate.PCOS patients may be more suitable for the IVM treatment.No matter PCOS or non-PCOS patients,IVM converted from IVF protocol had better pregnancy outcome than that of unstimulated cycle.

Objective To compare the outcomes of in-vitro maturation (IVM) and in-vitro fertilization (IVF) after early follicular phase gonadotropin-releasing hormone agonist (GnRH-a)down-regulation in infertile patients with polycystic ovary syndrome (PCOS).Methods From July 2010 to December 2012,72 infertile patients with PCOS undergoing assisted reproductive technology treatment in the Affiliated First Hospital of Wenzhou Medical University were enrolled in this study.The patients were divided into 2 groups,which were patients with early follieular phase down-regulation IVM (36 cases) at IVM group and early follicular phase down-regulation long protocol IVF (36 cases) at IVF group.The laboratory parameters and clinical outcomes were compared between two groups.Results (1) Lab parameters:a total of 442 oocytes were retrieved in group IVM,and 560 were in group IVF.The rate of mature oocytes of 83.8％ (469/560) and high-quality embryos of 70.9％ (212/299) at group IVF were significantly higher than that of group IVM [54.1％ (239/442) and 50.7％ (73/144),retrospectively,P ＜0.01].In group IVM,the average duration of gonadotropin (Gn) was (2.8 ± 1.5) days and the average dosage of Gn was (285 ± 169) U,which were significantly lower than (11.0 ± 1.0) days and (1499 ±165) U in group IVF (P ＜0.01).The mean number of oocytes retrieved 12.8 ± 2.5,fertilization rate of 64.8％ (155/239),and implantation rate of 31％ (23/74) in group IVM and 15.6 ±3.1,65.5％ (307/469),31％ (23/74) in group IVF,which did not reach statistical difference (P ＞0.05).(2) Clinical outcomes:the clinical pregnancy rate (17/31,55％) of IVF group was not significantly higher than that 44％ (14/32) at IVM group (P ＞ 0.05).The abortion rate was 1/17 at Group IVF and 1/14 in group IVM,which did not show statistical difference.Women at IVM group has no ovarian hyper-stimulation syndrome (OHSS) cycle,group IVF has 31％ (11/36) cycles presented moderate and severe OHSS.Conclusions Infertile patients with PCOS undergoing IVM and IVF treatment after early follicular phase GnRH-a down-regulation can get satisfactory laboratory and clinical outcome.In addition to short treatment cycle,IVM can also avoid the occurrence of OHSS completely,but it has a rising trend in the abortion rate.IVF has a high incidence of OHSS,meanwhile,it increases the dosage of gonadotropins.

To investigate the effects of cycloartocarpin A (ACR-2) and artocarpin (ACR-3), monomeric compounds isolated from Fructus Artocarpi Heterophylli, on apoptosis of SMMC-7721 and SGC-7901 cell lines.

OBJECTIVE: To investigate the effects of three compounds extracted from Tripterygium wilfordii Hook (TW) on angiogenesis in the chick chorioallantoic membrane (CAM). METHODS: Fifty fresh Hongkong Mahua chicken eggs were divided into five groups: PBS-treated group, TW1-, TW2- and TW3-treated groups and Rg3-treated group. After disinfection, the eggs were incubated for six days in a constant temperature box with the temperature being controlled within 37.8 degrees C, then exposed CAM, laid the filter papers with specimen on the CAM, and the eggs were incubated for another two days. CAM was fixed with the mixture of methyl alcohol and acetone at room temperature for about 15 min, and then cutting the CAM, taking photos and observing the angiogenesis in the CAM. RESULTS: There were many CAM vessels in the PBS-treated group and the blood vessel net could be seen clearly. The number of CAM vessels in the TW1-, TW2- and TW3-treated groups (10 microg/egg) was much less than that in the PBS-treated group. Furthermore, the frame of the vessels was not clear, and the color was obscure. Inhibition rates of angiogenesis in the TW1-, TW2- and TW3-treated groups were 80%, 60% and 100% respectively, while the inhibition rate of angiogenesis in the Rg3-treated group (10 microg/egg) was only 10%. CONCLUSION: TW1, TW2 and TW3 can obviously restrain the angiogenesis in CAM and still need further study.

Objective We tried to explore the relationship between work engagement and organizational citizenship behavior among nurses in tertiary hospitals in order to provide evidence for implementing targeted interventions to promote nurses' organizational citizenship behavior and job performance from a perspective of positive psychology.Methods Totally 511 nurses from four tertiary hospitals of Jinan city were enrolled using multistage sampling.Data were collected with Utrecht Work Engagement Scale (UWES-9) and Chinese Organizational Citizenship Behavior Scale.Data analysis included descriptive analysis,Pearson correlation analysis and stepwise multiple regression analysis.Results The average scores of work engagement and organizational citizenship behavior were (3.82 ± 1.08) and (5.89 ± 0.66),respectively.Work engagement accounted for 25.4％ of the variance in identification with the company,14.6％ of the variance in altruism and 18.7％ of the variance in conscientiousness.Conclusions Work engagement is a significant predictor of organizational citizenship behavior.Nurse managers are suggested to take actions in aspects of professional practice environment,resources allocation and staff training so as to enhance nurses' work engagement and subsequent their organizational citizenship behavior.

Objective To investigate the correlation between the drug resistance of Helicobacter pylori (H .pylori )and clinical eradication efficacy of bismuth-based quadruple therapies,and to guide clinical rational drug use in the region.Methods A total of 260 patients with H .pylori infections were collected.H .pylori from biopsied gastric mucosa tissues were isolated and cultured.Drug resistant rates of isolated H .pylori to metronidazole,clarithromycin,amoxicillin,levofloxacin and furanzolidone were tested.Patients were randomly divided into clarithromycin,levofloxacin,furanzolidone and metronidazole groups by completely randomized design.All patients received bismuth potassium 220 mg,esomeprazole 20 mg and amoxicillin 1 000 mg twice daily,and according to group received clarithromycin 500 mg, levofloxacin 200 mg,furanzolidone 100 mg and metronidazole 400 mg,twice daily,espectively.The treatment course was 10 days.At least four weeks after treatment,13 Curea breath test or 14 Curea breath test was taken.According to the intention to treat (ITT)and per-protocal (PP),the eradication rate of each group was caculated.Chi square test was performed to compare the differences between groups. Results The drug resistant rate of H .pylori to metronidazole,clarithromycin,amoxicillin,levofloxacin and furanzolidone was 94.2% (146/155 ), 21 .3% (33/155 ), 2.6% (4/155 ), 5 .8% (9/155 ) and 1 .9%(3/155),respectively.According to ITT analysis,the eradication rate of clarithromycin group, levofloxacin group,furanzolidone group and metronidazole group was 81 .5 %(53/65 ),90.8%(59/65 ), 93.8% (61/65 )and 75 .4%(49/65),respectively.And according to PP analysis which was 84.1 %(53/63),92.2%(59/64),95 .3%(61/64)and 79.0%(49/62 ),respectively.The differences between furanzolidone group and metronidazole group,clarithromycin group were staistcally significant (χ2ITT =8.509 and 4.561 ;χ2PP = 7.592 and 4.323,all P < 0.05 ).There was no statistical significance in the H .pylori eradication rate between resistant strains and sensitive strains of each group.Conclusion Bismuth-based quadruple therapy can overcome antibiotic resistance,the eradication rate of protocal with furanzolidone is higher and with good safety,which can be the first-line treatment for H .pylori eradication.
