Objective To investigate the status of self-management behaviors and sense of coherence (SOC) in patients with type 2 diabetes as well as their correlation. Method A total of 348 patients with type 2 diabetes participated in the survey by way of the general demographic data form, diabetes self-care scale (2-DSCS) and sense of coherence scale (SOC-13). Results The total score on 2-DSCS was (65.61 ± 14.55), and 17.24%of them were scored fairly well. The total score on SOC-13 was (63.25 ± 11.46), with an average score of (4.87 ± 0.88) on every dimension of it. The total score on 2-DSCS together with its dimensions was positively correlated with the total score on SOC-13(P<0.05, P<0.01). Conclusions The SOC and self-management in patients with type 2 diabetes should be enhanced. In order to improve the level of self-management, nurses should take some individualized interventional measures based on the level of SOC in patients.

The effects of vascular endothelial growth factor (VEGF) on neural differentiation of human embryonic stem cells (hESCs) in vitro and the possible mechanism were observed. The hESCs lines, TJMU1 and TJMU2, were established and stored by our laboratory. hESCs differentiated into neuronal cells through embryonic body formation. In this induction process, hESCs were divided into three groups: group A, routine induction; group B, routine induction+10 ng/mL VEGF; group C, routine induction+10 ng/mL VEGF+10 ng/mL VEGFR2/Fc. OCT4, Nestin and GFAP in each group were detected by RT-PCR, and the cells expressing Nestin and GFAP were counted by immunofluorescence. The percentage of Nestin positive cells in group B was significantly higher than in groups A and C, while the percentage of GFAP positive cells in group B was significantly lower than in groups A and C (P<0.01). There was no significant difference between groups A and C (P>0.05). It was concluded that VEGF, via VEGFR2, stimulated the neural differentiation of hESCs in vitro.

Objective To explore the application of mini-clinical evaluation exercise (Mini-CEX) in training the diagnostic thinking ability for clinical interns.Methods 83 interns who came to the First People's Hospital of Lianyungang for clinical practice in June 2015 were divided into the experimental group (45 interns) and the control group (38 interns) according to their schools.The two groups received the same clinical teaching according to internship program of five-year clinical medicine,while the experimental group had to take a weekly Mini-CEX training in chnical sections.The diagnostic thinking ability of the two groups was measured by the Diagnostic Thinking Inventory in Chinese version at the beginning and the end of the internship respectively.SPSS 21.0 was applied to processing the data.Measurement data were expressed as mean plus or minus standard deviation,and t test was used in the comparison between groups.Results At the end of the internship,the total score of diagnostic thinking,the score of knowledge structure in memory and the score of flexibility in thinking of the experimental group were higher than scores at the beginning statistically,and the experimental group had a statistically higher score than the control groups in knowledge structure in memory [(69.36 ± 4.28) vs.(66.95 ± 4.78),P=0.018].Conclusion Mini-CEX training can enhance the clinical diagnostic thinking ability of interns by improving their knowledge structure in memory.

AIM: To investigate the heterogeneity of basal intracellular free calcium concentration( i) in peritoneal macrophages(PM) and whether it is relative to the reactivity of PM at the single cell level. METHODS: i implicated stimulated were measured by fluorescent microscopic imaging system after loading with fluorescent probe fura-2/AM. Superoxide(O _2)produced by single PM was determined by modified NBT test. RESULTS: The values of basal i determined in 392 PMs of 7 mice showed normal distribution [(54?24) nmol/L, n=392] with wide range(less than 20 nmol/L to more than 100 nmol/L), among which about 50% were in the range of 40-60 nmol/L. When stimulated with PMA or fMLP, i was increased, the peak values were positively correlated with the basal i in one mouse(PMA stimulated cells: r=0.52, P

The author used five Chinese medicinal herbs,Barbat skullcap,Wolly yam,Anemarrhena,Phellodendron bark,and Dandelion herb,to make up decoctions to treat urinary tract infection(UTI). Ex-trinsic bacteriostatic experiments for colibacillus and bacillus proteus,which commonly occure in urinarytract infection,were observed.The result shows that both Barbat skullcap and Wolly yam are most effectivein treating UTI.So single Chinese medicinal herb can also be used in clinical.

Fibroblast growth factor -21 (FGF-21) is a recently discovered metabolic regulation factor, regulating glucose and lipid metabolism and increasing insulin sensitivity. FGF-21 is expected to be a potential anti-diabetic drug. Expression of FGF-21 as inclusion bodies has advantages for high yield and purity, but the bioactivity of the protein is almost totally lost after denature and renature. That is why FGF-21 is currently expressed in soluble form. As a result, the yield is considerably low. In this study, we used SUMO vector to express SUMO-human FGF-21 (SUMO-hFGF-21) in form of inclusion body. We optimized the culture conditions to increase the yield of the bioactive human fibroblast growth factor-21. We applied the hollow fiber membrane filtration column to enrich the bacteria, wash, denature and renature inclusion bodies. After affinity and gel filtration chromatography, we examined the hypoglycemic activity of FGF-21 by the glucose uptake assay in HepG2 cells. We also detected the blood glucose concentration of type 2 diabetic db/db model mice after short or long-term treatment. The results show that the yield of ihFGF-21 was 4 times higher than that of shFGF-21. The yield was 20 mg/L for ihFGF-21 vs. 6 mg/L for shFGF-21. The purity of ihFGF-21 was above 95%, while shFGF-21 was 90%. Compared with the traditional method of extracting inclusion bodies, the production cycle was about three times shortened by application of hollow fiber membrane filtration column technology, but the bioactivity did not significantly differ. This method provides an efficient and cost-effective strategy to the pilot and industrial production of hFGF-21.

BACKGROUND:It is reported that bone marrow mesenchymal stem cell(BMSC)transplantation might be a promising treatment for liver fibrosis.But the mechanism is still unclear.OBJECTIVE:To observe the hepatic stellate cells apoptosis induced by BMSC transplantation,and to study the mechanism of BMSC in treating hepatic fibrosis in vivo.METHODS:CCl_4 subcutaneous injection was performed to induce rat liver fibrosis.After 8 weeks of CCU injection,20 rats which underwent successful model establishment were randomly divided into experimental group and control group,10 in each group.The experimental group received MSC transplantation via tail vein injection,and the control group were given DMEM instead.The rats were killed and the livers were harvested at three time point,the day of MSC transplantation,3 days after transplantation,and 7 days after transplantation.The hydroxyproline content was detected by HE and Masson staining,and the expression changes of α-smooth muscle actin(α-SMA)proteins were determined using immunohistochemistry.The apoptosis of hepatic stellate cells were determined by α-SMA and TUNEL(terminal dUTP nick-end labeling)dual-staining.RESULTS AND CONCLUSION:After 8 weeks of CCU injection,the hydroxyproline content increased and histology indicated progress of liver fibrosis.At 7 days after MSC transplantation,the hydroxyproline in the liver was decreased,and the liver fibrosis was alleviated in the experimental group but aggravated in the control group.Immunohistochemistry indicated that α-SMA positive cells were increased at 8 weeks after CCU injection.At day 7 after transplantation,α-SMA positive cells in the experimental group were significantly less than control group(P ＜ 0.05).At 3 days after transplantation,the hepatic stellate cells apoptosis in the experimental group was significantly aggravated compared with control group(P ＜ 0.05).This suggested that MSC transplant was an effective treatment for liver fibrosis.MSC inducing hepatic stellate cells apoptosis may be one of the mechanisms.
