BACKGROUND:With the improvement of hemodialysis technology, the long-term survival rate of maintenance hemodialysis patients has been increased continual y. Nowadays, how to improve the quality of life in maintenance hemodialysis patients has been aroused widespread concern, and gradual y become the reliable indicator for comprehensive evaluation of the effect of hemodialysis. OBJECTIVE: To evaluate the effect of individualized intervention and col ective intervention on quality of life in maintenance hemodialysis patients. METHODS:Eighty maintenance hemodialysis patients, who had accepted more than 3 months of dialysis, were randomly divided into two groups (40 cases in the experimental group and 40 patients in the control group). Al the patients in the control group received 6 weeks of individualized intervention according to the pre-established schedule based on the hemodialysis routine care. Patients in the experimental group also have a period of six weeks of col ective intervention according to the pre-established weekly schedule based on the hemodialysis routine care. The quality of life of the patients was evaluated with MOS 36-item short form health survey and kidney disease quality of life short form before and after intervention. RESULTS AND CONCLUSION:After the intervention, both of the experimental group and the control group achieved significantly greater improvement than before in MOS 36-item short form health survey and kidney disease quality of life short form (P<0.01). The physical impact, overal health, emotional state, emotional impact, social function and energy of MOS 36-item short form health survey in the patients of the experimental group were higher than those of the control group after intervention (P<0.01);and the social quality, sleep, social support and patient satisfaction of kidney disease quality of life short form in the experimental group were higher than those in the control group (P<0.01). The results show that both individualized intervention and the col ective intervention based on the individualized intervention are effective in improving quality of life in maintenance hemodialysis patients and the col ective intervention can better improve the quality of life from physical, psychological and social aspects.

Objective To explore the effect of transtheoretical model-based(TTM) health education on the self-management of the patients with chronic obstructive pulmonary disease.Methods 100 patients of COPD were divided into the experimental group and the control group randomly,50 cases in each group.The patients in the control group received routine health education,while the patients in the experimental group received TTM education.All the patients were investigated with the self-management scale at baseline and 4,12 and 24 weeks after discharge.Results After the intervention,the scores of self-management in the experimental group were significantly higher than those in the control group,the difference was statistically significant.Conclusions TTM health education can improve the self-management skills in patients with COPD.

OBJECTIVETo study the protective effect of puerarin on MPP(+) -induced SH-SY5Y cells by chaperone-mediated autophagy (CMA).

METHODThe Parkinson's disease cell model was established by injuring SH-SY5Y cells with 1 mmol x L(-1) MPP+. The CCK-8 staining was adopted to detect the effect the puerarin of different concentrations on the survival rate of MPP(+)-induced SH-SYSY cells. The autophagosome formation was observed under transmission electron microscope. The AO staining showed the changes in the lysosome activity. RT-PCR was used to detect the changes in Lamp2a and Hsc70 mRNA expressions. The western blotting was adopted to test the expressions of Lamp2a, Hsc70 and alpha-synuclein protein in cells.

RESULTWithin the concentration range of 12. 5-50.0 micromol x L(-1), the pretreatment with puerain for 30 minutes could protect the injury of MPP+ in SH-SY5Y cells, and showed a certain dose-effect relationship. The AO staining and electron microscope showed the effect of puerain within the concentration range of 12.5-50.0 micromol x L(-1) on 1 mmol x L(-1) MPP(+)-induced SH-SY5Y cells; autophagosomes emerged in cells, and increased along with the rise in the puerarin dose. The results of the flow cytometry revealed that 50.0 micromol x L(-1) of puerarin could protect against the increase of the ROS level in 1 mmol x L(-1) MPP(+) -induced SH-SY5Y cells and prevent the oxidative injury. The results of RT-PCR and western blotting indicated that puerain within the concentration range of 12.5-50.0 micromol x L(-1) alleviated the MPP(+)-induced SH-SY5Y cell injury, and inhibited the accumulation of alpha-synuclein proteins in MPP(+) -induced SH-SY5Y cells by up-regulating Hsc70, Lamp2a mRNA and protein level.

CONCLUSIONPuerarin could protect against the MPP(+) -induced cell injury, whose protective mechanism may be related to the chaperone-mediated autophagy pathway of interventional molecules.

AIM: To investigate the possibility of 3T3 fibroblast growth on blood fibrin clot in culture medium with recombinant human basic fibroblast growth factor (rhbFGF). METHOD: Growth of the cells on blood fibrin clot was studied by phase-contrast, scanning and transmission electron microscopy and by Giemsa stain and MTT assay. RESULTS: The optimal concentration of rhbFGF for proliferation and survival of the cells was 100 ng/mL. The cells also grew on blood fibrin clot scaffold in the low-serum medium containing 100 ng/mL rhbFGF, and a greater number of the cells survived after 48 hours incubation compared to that after 24 hours. The elongated filopodia appeared to bridge the gaps among the fibroblasts after 24 hours incubation. Further incubation to 72 hours, a greater number of platycytes were found to be joined together by lamellopodia. CONCLUSION: 3T3 fibroblasts could grow and survive on blood fibrin clot in the low-serum medium containing rhbFGF, and a combination of blood fibrin clot and rhbFGF may have over proportional effects on wound healing.

ObjectiveTo investigate the effect of heart-regulating and mind-calming acupuncture on the expression of gap junction protein connexin43 (Cx43) in myocardial cells in a rabbit model of ventricular arrhythmia.MethodA rabbit model of ventricular arrhythmia was made by injecting barium chloride into the marginal ear vein. Forty New Zealand rabbits were randomized into control, model, acupuncture and medication groups. The acupuncture group received heart-regulating and mind-calming acupuncture[at Lingtai(GV10), Shendao(GV11), bilateral Neiguan(PC6)and Baihui(GV20)]and the medication group, oral gavage of propafenone. Rabbit left ventricle was taken after the completion of the experiment. Cx43 expressions were compared and analyzed usingan immunohistochemical staining technique and a computer image processing system.ResultCx43 expression decreased significantly in the model group compared with the control group (P<0.01) and increased in the acupuncture and medication groups compared with the model group (P<0.05). There was no significant difference in Cx43 expression between the acupuncture and medication groups (P>0.05).Conclusion Adjusting Cx43 expression in myocardial cells may be one of the target points for this acupuncture treatment of arrhythmia.

The relationship between 3 polymorphisms sites [interleulin-4 (IL-4), IL-4 receptor (IL-4R) alpha chain and activation-induced cytidine deaminase (AICDA)] and adult allergic asthma in China was studied. By using case-control method, DNA and clinical data were obtained from allergic asthmatic patients and compared with those in the control subjects. The subjects were genotyped for the IL-4 C-589T promoter polymorphism, the IL-4R alpha chain Q576R and the AICDA C8408T by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The results showed that the IL-4 C-589T was not associated with adult allergic asthma in China. However, the IL-4R alpha chain 576R/R and AICDA 8408T/T frequency was significantly increased in allergic asthma group as compared with that in the control group [odd ratio (OR) = 3.797 and 9.127, respectively; P < 0.01)] and was correlated with the increased plasma total IgE. These data suggested that the IL-4R alpha chain 576R/R and AICDA 8408T/T genotypes confer genetic susceptibility to adult allergic asthma in China.
