Objective To explore the effects of collaboration intervention on self-efficacy and self-perceived burden in stroke patients. Methods 92 stroke patients hospitalized in the neurology department from January to June, 2014 were divided into control group (n=46) and intervention group (n=46). The control group received routine nursing and the intervention group received collaboration intervention in addi-tion. They were assessed with Self-Efficacy for Managing Chronic Diseases and Self-perceived Burden Scale before and after intervention. Results There was no difference in the scores of self-efficacy and self-perceived burden between groups before intervention (t<0.585, P>0.05). The score of self-efficacy was more in the intervention group than in the control group (t=3.483, P<0.001) after intervention, and was less of self-perceived burden (t=-5.698, P<0.001). Conclusion The collaboration intervention can improve self-efficacy and relieve self-per-ceived burden in stroke patients.

In this study,we presented data that K562,YAC-1 and LAC-1 cells or tumor-membrane-associated protein could stimulate BCG-treated macrophages from BALB/c mice to produce cy-totoxic factor (M?-CF). CF-inducing activity of K562 membrane or tumor cells remainde afterheat-treated at 100℃ for 20 min, but decreased by trypsin digestion or NaIO_4 oxidixa-tion. Thisactivity was also hibited by ConA or D-Man, but not by Gal. and Giu. The results suggested thatgiycoprotein containing D-Man on tumor cell surface was responsible for traggering M?s toproduce CF.

OBJECTIVE:To develop a capillary electrophoresis method for determing the enantiomer of ceftriaxone Na.METHODS:A chiral resolving agent,?-cyclodextrin,was employed as chiral additive for ceftriaxone Na enantiomeric separation by capillary electrophoresis.In different electrophoresis polarity mode,the effect of pH of background electrolyte and the concentration of ?-cyclodextrin were investigated.RESULTS:The optimal conditions for enantiomeric separation were as follows:separation voltage:28kV,buffer solution:NaH2 PO4 50mmol/L,?-CD 0.04mmol/L,Tirs 3.0mmol/L,pH7.15.CONC_LUSION:The method is simple,sensitive,rapid and accurate,and can be used for the quality control of ceftriaxone Na enantiomers.There was significant difference in contents of enantiomers of ceftriaxone Na between products of two factories.We suggest that a quality control method for ceftriaxone Na enantiomer should be established,which will provide scientific basis for quality control of drug and clinical choice of effective antibioties.

BACKGROUND: The small change of the membrane potential (Em) of vascular smooth muscle cells (VSMC) could result in significant alteration in tension, and the membrane depolarization was closely associated with the development of hypertension.OBJECTIVE: To study the resting Em of VSMC from the middle cerebral artery (MCA) of stroke-prone spontaneously hypertensive rats (SHRSP) and the reactivity of Em to KCl and norepinephrine (NE).DESIGN: An animal experiment of comparative analysis.SETTING: Institute of Materia Medica, Shandong Academy of Medical Sciences.MATERIALS: Eighteen male SHRSP and 26 male Wistar rats were used.METHODS: ① Rats in both groups were anesthetized with intraperitoneal injection of ethyl carbamate (1 g/kg), the brains were removed quickly, and the Em of VSMC was recorded by intracellular microelectrodes. ② The effects of different concentrations of KC1 (10, 20, 50 mmol/L) and NE (10-7,10-6, 10-5 mol/L) on the Em of VSMC were observed.MAIN OUTCOME MEASURES: ① Em of VSMC in both groups; ②Effects of different concentrations of KC1 and NE on the Em of VSMC.RESULTS: ① The Em was obviously lower in SHRSP than in the Wistar rats [(-48.2±3.1), (-64.4±4.3) mV]. ② Both KC1 (10, 20, 50 mmol/L)and NE (10-7, 10-6, 10-5 mol/L) could cause the depolarization of Em of MCA in a concentration-dependent manner. The reactivity to MCA of SHRSP was obviously increased as compared with the Wistar rats.CONCLUSION: The resting Em of VSMC from the MCA of SHRSP was lower, and the reactivity of VSMC to KCl and NE was significantly stronger than that of Wistar rats.

To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.

Objective To explore the relationship of glucagon in many phases with insulin and blood glucose in patients with insulin resistance syndrome,and to provide theory and practice support for the treatment of insulin resistance syndrome.Methods Totally 93 patients with insulin resistance syndrome (observation group),107 patients with type 2 diabetes (diabetes group) and 80 patients without diabetes (non-diabetes group) in our hospital from July 2008 to October 2011 were selected.The general information were collected.Patients with stable blood glucose stopped taking anti-diabetic drug for 10 hours.The fasting blood glucose,fasting insulin,and fasting glucagon were tested.Then patients took 75 g glucose,blood glucose,insulin and glucagon were respectively tested after 30 and 120 minutes.Data were processed by SPSS 17.0 software,and P＜0.05 was considered as being statistically significant.Results The levels of fasting glucose,early phase glucose and late phase glucose were lower in observation group than in diabetes group,but higher than in non-diabetic group,and the differences were statistically significant (all P＜0.05).The levels of fasting insulin,the early phase insulin,and late phase insulin were higher in observation group than in diabetes group and non-diabetic group,and the differences were statistically significant (both P＜0.05).The insulin levels in observation group and diabetes group were lowest after fasting and were highest at 120 minutes after the oral glucose load,but the insulin levels were highest at 30 minutes and decreased at 120 minutes after the oral glucose load in non diabetic group.The differences in fasting glucagon,early phase glucagon and late phase glucagon among three groups were statistically significant (all P＜0.05).The glucagon levels in observation group and diabetes group were lowest after fasting and highest at 120 minutes after the oral glucose load,but the glucagon levels in non-diabetic group were highest after fasting and were lowest at 120 minutes after the oral glucose load.There were positive correlations between glucagon and glucose in 3 phases in observation group (r=0.65,0.63,0.67,respectively,all P＜0.05).Conclusions Glucagon and glucose in different phases are positively correlated in patients with insulin resistance syndrome,and blood glucose can be controlled by improving glucagon secretion.

Objective To investigate the effect of deoxyribonucleic acid (DNA) methylation on the expression of hepatocyte nuclear factor-4α (HNF4c) and its role in the expression of HNF4α regulated by transforming growth factor-β1 (TGF-β1).Methods The expression of HNF4αP1 mRNA in six human hepatoma cell lines (HepG2,Huh-7,Hep3B,SMMC-7721,BEL-7405 and FOCUS),20 hepatic carcinoma specimens and corresponding adjacent tissues was detected by real-time reverse transcription polymerse chain reaction (real-time RT-PCR).The methylation status of the promoter region of HNF4αP1 in six human hepatoma cell lines was examined by bisulfite sequencing PCR (BSP).FOCUS cells were treated with 5-aza-2'-deoxycytidine (5-AZA-CdR) and then the methylation status of the promoter region of HNF4αP1 was examined by BSP.The expression of HNF4αP1 mRNA was detected by real-time RT-PCR.The six human hepatoma cell lines were treated with TGFβ1 and the expression of HNF4αP1 mRNA was detected by real-time RT-PCR.FOCUS cells were cotreated with 5-AZA-CdR,TGF-β1 and 5-AZA-CdR.The expression of HNF4αP1 mRNA was detected by real-time RT-PCR,and t test was performed for statistical analysis.Results Among 20 human hepatic carcinoma specimens and corresponding adjacent tissues,the expression of HNF4αP1 mRNA of 13 human hepatic carcinoma specimens was lower than that of corresponding adjacent tissues (t=2.350,P＜0.05).The relative quantity of the expression of HNF4αP1 mRNA was higher in Hep3B,HepG2 and Huh-7 cells,whereas that in SMMC-7721,BEL-7405 and FOCUS cells was lower.The methylation of the promoter region of HNF4αP1 in HepG2,Huh-7 and Hep3B was lower,but that in SMMC-7721,BEL-7405 and FOCUS was higher.Along with the increasing of the concentration of 5-AZA-CdR (0,0.1,1.0 and 2.5 μmol/L),the degree of the methylation of the promoter region of HNF4αP1 in FOCUS cells gradually decreased (61％,46％,32％ and 27％),and however the relative quantity of the expression of HNF4αP1 mRNA gradually increased ((9.661 ± 0.336)×10-7,(2.001±0.432)×10-6,(3.689±0.714)×10-6and (4.732±2.451)×10-6).After stimulated with TGF-β1,the relative quantity of the expression of HNF4αP1 mRNA was downregulated in HepG2,Huh-7 and Hep3B cells in which the methylation of the promoter region was low (t=12.994,8.441,and 9.032,all P＜0.01).There was no significant difference in the relative quantity of the expression of HNF4αP1 mRNA in SMMC-7721,BEL-7405 and FOCUS cells in which the methylation of the promoter region was high (all P ＞ 0.05).The relative quantity of the expression of HNF4αP1 mRNA in 5-AZA-CdR treated FOCUS cells ((4.972±0.035) × 10-6) was higher than that of control group ((1.411 ± 0.104) × 10-6) and the difference was statistically significant (t=13.212,P＜0.01).The relative quantity of the expression of HNF4αP1 mRNA in FOCUS cells co-treated with 5-AZA-CdR and TGF-β1 was lower than that in cells treated with 5-AZA-CdR alone and the difference was statistically significant ((1.181 ± 0.132) × 10-6 vs (4.972 ± 0.035) × 10-6,t=13.873,P＜0.01).Conclusions The expression of HNF4αP1 is down-regulated in hepatic carcinoma tissues.DNA methylation may regulate the expression of HNF4αP1 in hepatoma cells.The methylation of HNF4αP1 promoter region inhibits the regulating function of TGF-β1 in the expression of HNF4αP1.
