Objective:To investigate the effects of sleep quality on cognitive function in elderly patients undergoing hemodialysis.Methods:In this cross-sectional study, the cognitive function in hemodialysis patients was evaluated by Montreal Cognitive Assessment(MoCA)and the sleep quality was accessed by Pittsburgh sleep quality index(PSQI). The related indexes of cognitive function were compared and the relationship between cognitive function and sleep quality was analyzed by using multiple binary Logistic regression method.Results:A total of 121 elderly hemodialysis patients aged 67.4±7.2 years with cognitive impairment of 76 cases(62.8%)were included in the study.Numbers(%)of cases with very good, good, general and poor sleep quality were 33(27.3%), 39(32.2%), 14(11.6%)and 35(28.9%), respectively.The proportion of patients with pretty good sleep quality was lower in cognitive impairment group than in normal cognitive group(13/76 or 17.1% vs.20/45 or 44.4%, P<0.001). The proportion of patients with poor sleep quality was higher in cognitive impairment group than in normal cognitive group(29/76 or 38.2% vs.6/45 or 13.3%, P<0.05). Multiple binary Logistic regression analysis showed that age( OR: 1.128, 95% CI: 1.083-1.175, P<0.001), a education level( OR: 0.353, 95% CI: 0.151-0.556, P<0.05), hypertension( OR: 2.508, 95% CI: 1.189-5.291, P<0.05), diabetes( OR: 1.913, 95% CI: 1.045-3.502, P<0.05), stroke( OR: 4.044, 95% CI: 1.439-11.365, P<0.05), dialysis age( OR: 1.016, 95% CI: 1.010-1.023, P<0.001), KT/V( OR: 0.025, 95% CI: 0.005-0.122, P<0.001)and parathormon(iPTH)( OR: 1.002, 95% CI: 1.000-1.003, P<0.05)were associated with cognitive impairment.After adjusting for above factors, sleep quality was also correlated with cognitive impairment( OR: 1.180, 95% CI: 1.108-1.258, P<0.001), showing that the risk of cognitive impairment increased by 1.18 times with every one point increase in PSQI scores. Conclusions:Cognitive impairment is associated with age, education level, hypertension, diabetes, stroke, dialysis age, KT/V and iPTH in elderly hemodialysis patient, and sleep quality is also an independent risk factor for cognitive impairment.

Oblective To observe the effect of bile reflux on the intragastric pH. Methods We used ambulatory intragastric pH monitoring along with simultaneous Bilitec 2000 to measure the pH and absorbance of the mixed gastric juice diluted with bile with increasing bilirubin concentration in vitro and the yellow and clear gastric juice aspirated under endoscopy. In vivo,we studied 20 functional dispepsia patients for 24 h with simultaneous intragastric pH and bilirubin monitoring. Results In vitro dilutions,the absorbance value reached to 0. 900 while the concentration was only 20% ,but when the pH of the solution was more than 4,it′s concentration was already up to 60％. The mean absorbance of the yellow gastric juice(0. 348± 0. 131) was significantly higher than that of the clear juice (0. 008 ± 0. 003)(P＜0.05). The pH of 80％ yellow gastric juice was less than 4, the percentage was not significantly different from the clear samples (81％) (P＞0. 05). The pH showed no correlation with the absorbance in the yellow and clear groungs. Eight of the 12 patients with the spontaneous nocturnal episcodes of alkalinization had simultaneous increase of absorbance,4 of the 8 subjects with no aikalinization had increase of absorbance. Gonclusion In some concentration,bile reflux affect little on the intragastric pH.

Objective In this study,we elucidated the role of high mobility group box chromosomal protein 1 (HMGB1) in collagen-induced arthritis (CIA) rat and the antagonist role of ethyl pyruvate by using a rat model of CIA as the research object by comparing the expression of HMGB1 in normal control group,CIA model group and ethyl pyruvate group.Methods Thirty-six rats were randomly divided into 3 groups (n=12):normal control group,CIA group and ethyl pyruvate group.Then the 6 rats were dissected at the 6th,9th week respectively.Thc expression of HMGB1 was analyzed by immunohistochemistry and Pathology-image analysis software in the cytoplasma.The expression of HMGB1 mRNA with real time-polymerse chain reaction (PCR) was evaluate,and the HMGB1 expression of each group were compared with t-test.Results The immunohistochemical results of HMGB1 showed that the expression intensity in the normal control group,CIA model group and ethyl pyruvate group was 2.1±0.6,7.3±1.2,6.0±1.2 respectively at the 6th week; and 2.2±0.7,12.4±4.5,5.5±1.0 at the 9th week respectively.The HMGB1 mRNA real time-PCR results had shown that the relative quantification of the normal control group and CIA model group were 1,2.865,2.602respectively at the 6th week and 1.005,4.694,1.729 at the 9th week.At those two points, the HMGB1 expressions of HMGB1 antagonist group were significantly higher than those of the normal controls (P＜0.05).In addition,there was statistical significant difference(P＜0.05) in the HMGB1 expression when compared with the placebo group.Furthermore, when the degree of HMGB1 expression among the three groups was compared,the HMGB1 antagonist group was decreased significantly (P＜0.05).Conclusion The results has demonstrated that HMGB1 could induce inflammation in the synovial tissue of CIA rats,and has provided the rationale that HMBG 1 could be the target of treating rheumatoid arthritis (RA).The results of this study have shown that ethyl pyruvate could antagonize the effect of HMGB1.This finding may provide a new therapeutic target for the treatment of RA.

AIM: To explore the effect of collagen and C-erbB-2 protein on the adhesion and the proliferation in hepatocellular carcinoma cells.METHODS: Hepatocellular carcinoma cell line(HepG-2) identified to positive for C-erbB-2 gene was used to study the adhesion and the growth feature by the action of rat tail collagen and C-erbB-2 antibody.RESULTS: The action of rat tail collagen to potentiated the adhesion in HepG-2 cells was significantly but no proliferation effect was observed. C-erbB-2 antibody inhibited the adhesion and proliferation of HepG-2 cells and also abolished the potentiated effect of rat tail collagen on the adhesion in HepG-2 cells.CONCLUSIONS: The signaling transduction mediated by C-erbB-2 protein was correlated to the adhesion and the proliferation of HepG-2. The blockage of C-erbB-2 gene signal transduction may be a strategic target to the treatment of liver cancer in the future.

AIM: To explore the effects and mechanism of cobra venom serum on the proliferation in HL60 cells. METHODS: Established the HL60 cells as a target to study the growth feature by the action of cobra venom serum. The agarose gel electrophoresis and flow cytometry analysis were used to demonstrate apoptosis. RESULTS: Compared with the control group, the cells were inhibited significantly by the action of cobra venom serum. A characteristic DNA "ladder" was detected by using agarose gel electrophoresis. By flow cytometry analysis, it was proved that most apoptosis of HL60 cells occurred when cultured with cobra venom serum. CONCLUSION: Cobra venom serum inhibited the HL60 cells in vitro, which was related to apoptosis. This may introduce a new way to the treatment of leukemia.

ObjectiveTo observe the effect of digital auditory activation and touching intervention on infants with cerebral dysfunction.Methods388 infants with perinatal high-risk factors and abnormal result of Denver Development Screening Test (DDST) were randomly divided into group A (n=135), group B (n=128) and group C (n=125), and treated with digital auditory activation combined with touching (group A), simple touching (group B) and simple drug (group C) with 10 days as a course. All infants were tested with DDST after one therapeutic course, and tested again with DDST after the infants of group B and group C treated continuously for six therapeutic courses; and all infants were assessed with the Gesell development quotient (DQ) after six months.ResultsAfter one therapeutic course, normal rate of DDST was 71.11% in group A, 26.69% in group B and 20.00% in group C. After six therapeutic courses, that was 90.37 % in group A, 62.50 in group B and 40.00% in group C. After six months, the children with the Gesell DQ over 86 scores was 125 (92.60%) in group A, 90 (70.31%) in group B and 62 (49.60%) in group C. There were significant differences among three groups ( P<0.01).ConclusionThe digital auditory activation combined with touching has short therapeutic course and high efficacy, so it is a good therapeutic method for infants with cerebral dysfunction.

OBJECTIVETo evaluate the clinical efficacy of Shenfu Injection (SFI), as a adjuvant therapy, in treating patients of ischemic cardiomyopathy with heart insufficiency (ICP-HI).

METHODSOne hundred patients of ICP-HF were equally randomized into two groups, the SFI group and the control group. All received the conventional treatment, but to patients in the SFI group SFI was given additionally via intravenous injection, 60 mL once a day, 10 days each month, the treatment course was 6 months. Changes of cardial functional grading, 6-min walking distance, echocardiographic indices, plasma N terminal pro-brain natriuretic peptide (pro-BNP) level were observed before and after treatment, and the occurrence of major adverse cardiovascular events (MACE) and mortality in patients were observed as well.

RESULTSAs compared with the conventional treatment alone, additional application of SFI showed a more significant efficacy in improving NYHA functional grade and 6-min walking distance, reducing the diameters of left ventricular at end diastole and systole, increasing left ventricular ejection fraction, and decreasing plasma N terminal pro-BNP level (P <0.05). The occurrence of MACE and the mortality in the SFI group were significantly lower than those in the control group respectively (P <0.05).

CONCLUSIONSBased on the conventional treatment, the adjuvant therapy of SFI could improve the cardiac function, improve the quality of life, ameliorate ventricular reconstruction, and decrease the occurrence of cardiovascular events in patients of ICP-HI.
