Objective To evaluate the effects of nutritional education by "knowledge,attitude and behavior" on health improvement in patients with type 2 diabetes.Methods One hundred and sixteen patients with type 2 diabetes were selected with nutritional education intervention by "knowledge,attitude and behavior",and another 100 diabetic patients as control group with regular education for six months,to follow up their changes in awareness of diabetes-related nutritional knowledge and biochemical examinations. Results Ninety-eight patients in intervention group completed follow-up.Awareness of diabetes-related nutritional knowledge,intake of nutrients and indices of metabolism in intervention group were significantly different from those in control group,including serum level of glycosylated hemoglobin A1c(HbA1c)[(6.1 ?0.9)% vs.(7.7?2.3)%,t=6.421,P

Objective To explore the relationship of perceived professional benefit, job satisfaction, and retention willingness of nurses. Methods Convenience sampling method was adopted to investigate 493 nurses from 3 tertiary grade A hospitals in Taian. Results The mean scores of nurses′perceived professional benefit, job satisfaction, and retention willingness were 134.19 ± 19.79,121.52 ± 18.41, and 21.18 ± 4.23, respectively. Perceived professional benefit and job satisfaction were positively correlated with retention willingness (P<0.01). Job satisfaction played a partial mediation role in the relationship between perceived professional benefit and retention willingness. Conclusion Job satisfaction and perceived professional benefit have a positive influence on nurses′retention willingness .

Objective To analyze the clinical characteristics of Mycoplasma pneumoniae pneumonia in children under 2 years old. Methods The clinical features and treatment outcomes were analyzed in 57 children under 2 years old and compared with 153 children more than 2 years old. Results Compared with children more than 2 years old, in children under 2 years old, the number of cases with fever was fewer, the fever peak was lower and the lasting time was shorter. However, in children under 2 years old, the severe pulmonary signs were more common, the incidence of wheeze was higher, meanwhile, the count of white blood cells (WBCs) was signiifcantly increased, more small pieces of lfuff shadow was showed on chest X-ray, and the pulmo-nary complications were fewer, less corticosteroid was needed for treatment. After one-week therapy, the chest X-ray shadows were disappeared in most of children. Complications out of lungs, such as rash, liver function damage and cardiac damage can be found in both groups and no signiifcant difference (P>0.05). Conclusions Mycoplasma pneumoniae pneumonia in children under 2 years old had the characteristics of mild symptoms, severe pulmonary signs, few pulmonary complications, light systemic inlfammations and mild radiological changes.

Teaching feedback has been affected by many factors including education theory, culture diversity and so on.Article analyized the teaching feedback in United States clinical education in a group of the visiting student’s experience in Harbor-UCLA Medical Center.In clinical education, the aim of teaching can only be could be successfully reached by consideration the specific teaching contact and students’idiosyncrasy and flexible teaching feedback utilization.

Objective:To explore changes of plasma levels of catestatin (CST)and brain natriuretic peptide (BNP)in patients with chronic heart failure (CHF)and their correlation.Methods:A total of 60 CHF patients treated in our department of cardiology from Jun 2014 to Dec 2014 were enrolled as CHF group,another 60 healthy subjects un- dergoing physical examination were regarded as normal control group.Enzyme linked immunosorbent assay was used to measure plasma levels of CST and BNP in two groups,then the results were compared.Linear correlation analysis was used to analyze the correlation between plasma levels of CST and BNP.Results:Compared with normal control group,there were significant rise in plasma levels of CST [(0.40±0.15)ng/L vs.(0.88±0.34)ng/L]and BNP [(30.84±12.56)ng/L vs.(678.21±120.35)ng/L]in CHF group,P<0.01 both.Linear correlation analysis indi- cated that plasma CST level was significant positively correlated with BNP level (r=0.38,P<0.05).Conclusion:Catestatin level is significant positively correlated with the most sensitive cardiac function index—brain natriuretic peptide level,suggesting that it could be used as a new biochemical marker diagnosing or excluding heart failure.

Recombinant antibodies have become the major growth trends in biotech industry following their success on therapeutic application and good revenue. But the low level of mammalian expression and laggard fermentation process constrained the development of antibody industry in China. The global advances of antibody industry were reviewed, compared the respective advantage between dihydrofolate reductase and glutamine synthetase expression system, continuous perfusion and fed-batch processes were compared. Finally, based on the knowledge and experience of antibody expression and fermentation, the suitable strategy of antibody industrialization, e.g. the fermentation model and scale, should depend on the comprehensive consideration of entrepreneur for the productivity, manufacturing capacity and market revenue. It may be a wise choice to use glutamine synthetase expression system and continuous perfusion process for the need of Chinese antibody industrialization.

Objective One of the major obstacle to the successful treatment of cancer in clinic is the drug-resistance phenotype.In this study,the effect of realgar(REA) on the induction of apoptosis and the reversal of drug resistance were investigated. Methods Human breast cancer line MCF-7 and its adriamycin(ADM) resistant counterpart MCF-7/ADM cells were used in this study.15mg/L REA and 25mg/L REA were selected as non-cytotoxic dose and low-cytotoxic to MCF-7/ADM cells respectively by MTT assay.Then,they were adopted to affect the growth of MCF-7/ADM cells. MTT assay was used to analyze the effect of REA on drug sensitivity to ADM.The cells apoptosis was detected by transmission electron microscope and flow cytornetry.The expressions of anti-apoptosis protein Bcl-2 were detected by flow cytometry.Finally,the intracellular accumulation of ADM in MCF-7/ADM cells was detected by fluorescent-spectrophotometry. Results REA reversed the drug-resistance of ADM in MCF-7/ADM cells with dose-dependent relationship.When 15mg/L REA or 25mg/L REA was added into the culture,the 50% inhibitory concentration(IC_(50)) of ADM in MCF-7/ADM cells was reduced from 30.4mg/L to 13.2mg/L and 10.8mg/L(P

Objective To evaluate the significance of the panel of 6 microsatellites in detection of bladder cancer. Methods In the tumor tissue and urine sediment of 32 cases of bladder cancer 10 microsatellites were chosen and PCR-SSLP silver staining assay was conducted according to the methods described in the literature and our previous study.15 cases of non-bladder cancer served as controls. Results Microsatellite alternate (MA) was found in 30 out of 32 cases of bladder cancers,the sensitivity being 93.8%.The MA of urine sediment of 15 cases of non-bladder cancer was negative,the specifity being 100.0%.Among the 10 microsatellites, 6 ones were chosen;the MA positivity of the panel of the 6 ones was 90.6% (29/32).This result was not significantly different from that of the panel of 10 microsatellites. Conclusions MA assay is a sensitive,effective method for detection of bladder cancer.Compared with the panel of 10 microsatellites,the panel of 6 microsatellites may be a better tool for detection of bladder cancer.
