Chinese Journal of Practical Nursing 2017;33(20):1540-1543
Objective To investigate the effect of cluster nursing in the prevention of aspiration pneumonia in patients with cerebral infarction. Methods A total of 72 patients with acute cerebral infarction from January 2014 to January 2014 were recruited and divided into 2 groups with 36 cases each by random digits table method. The patients in control group were given diet nursing, nursing of sputum ejection, education of disease related knowledge and another routine nursing methods. While cluster nursing such as the application of swallowing function training, feeding management, homemade angle measuring instrument for position management were conducted on the patients in intervention group. The difference of incidence of aspiration pneumonia, improvement of swallowing function, and patient satisfaction between two groups were compared. Results The incidence of aspiration pneumonia was 5.56%(2/36) in intervention group and 25.00%(9/36) in control group, and the difference was statistically significant (χ2=5.258, P=0.022).The swallowing function ratings after treatment in intervention group was also obviously better than that in control group, and the difference was statistically significant (χ2=7.943, P=0.036). The patient satisfaction was 94.44%(34/36) in intervention group and 63.89%(23/36) in control group, and the difference was statistically significant(χ2=17.526,P=0.000). Conclusions Cluster nursing can effectively reduce the risk of aspiration pneumonia in acute cerebral infarction patients, and help to improve the patients' swallowing function and relationship between nurses and patients, has certain clinical application value.
2.The effect of EC on the ET-induced fever in rabbits
Chinese Journal of Pathophysiology 1986;0(04):-
The effects of intravenous injection of purifed EC on the rectal tempera-ture in normal rabbits and febrile rabbits induced by ET and concentrations of Fe~(2+), Zn~(2+),Cu~(2+) in serum were observed. The results showed that EC could lower the rectal tempera-ture in normal rabbits and also the increased rectal temperature in febrile rabbits. Mean-while, EC could inhibit the formation of the second phase of ET-fever. But EC had noeffect on the changed concentrations of FC~(2+), Zn~(2+), Cu~(2+) in serum caused by ET. Thesefindings suggest that EC may particiate in the regulation of body temperarure under physio-logical and febrile conditions, but not of acute phase response produced by ET.

Journal of Huazhong University of Science and Technology (Medical Sciences) 2009;29(6):689-96
Mitofusin-2 (Mfn2) gene expression is positively correlated with insulin sensitivity in patients with type 2 diabetes. However, it is unclear if Mfn2 is involved in carbohydrate metabolism and lipid homeostasis. In order to investigate the specific functions of Mfn2 in glycometabolism and lipid homeostasis in BALB/c mice, a RNA interference technique-mediated hydrodynamic injection was developed, in which short hairpin RNAs (shRNAs) were used to inhibit the Mfn2 expression in vivo. Seventy-two mice were randomly divided into two groups: the Mfn2 reduction group (Mfn2/shRNA) and the negative control group (NC). Intraperitoneal glucose tolerance tests and intraperitoneal insulin tolerance tests were used to evaluate glycometabolism and insulin sensitivity. D-(3-(3)H) glucose or (3)H(2)O was injected into the tail vein or intraperitoneally to facilitate the calculation of the rate of hepatic glucose production and fatty acid synthesis in vivo. The results showed that, in Mfn2/shRNA mice, the liver Mfn2 protein was significantly decreased, and fasting blood glucose concentrations were increased by approximately 48%, when compared with the NC mice. In parallel with the changes in fasting glucose levels, hepatic glucose production was significantly elevated in Mfn2/shRNA mice. When insulin was administrated, these mice exhibited impaired insulin tolerance. It was also found that the reduction of Mfn2 markedly decreased the rate of fatty acid synthesis in the liver, and the Mfn2/shRNA mice exhibited hypertriglyceridema. Taken together, our results indicate that Mfn2 plays an important role in maintaining glucose and lipid homeostasis, and in the development of insulin resistance in vivo.

Objective To assess the effect of intraperitoneal interstitial implant of Sustained-release 5-Fluorouracil during operation for advanced rectal cancer. Methods One hundred and four cases with advanced rectal cancer were enrolled into the study and divided into 3 groups: treatment group 1(n = 37), underwent combined hypotonic peritoneal chemo-hyperthermia and Sustain-released 5-fluorouracil implantation treatment during operation; treatment group 2(n = 34), underwent combined intraoperative hypotonic peritoneal chemohyperthermia and early postoperatively intraperitoneal chemotherapy treatment; and control group(n = 33),underwent peritoneal lavage during radical resection alone. Results Digestive tract toxicity in group 1 was significantly lower than that in group 2(2. 70% vs. 20. 59%, x2 = 9. 104, P < 0. 05). There were significant difference on 1 year survival rate among the three groups. The 2-year survival rate of group 1 was significantly higher than that in the control group (78. 37% vs. 48. 48%, x2 = 1. 297 ,P < 0. 05). After two years follow-up the 2-year local recurrence rate of group 1 was significantly lower than that in the control group(21.62% vs 32. 35 %, x2 = 7. 001, P < 0. 05). However, no significant difference was found compared to group 2, which was 32. 35%. Conclusion lntraperitoneal interstitial implant of Sustain-released 5-Fluorouracil during operation is an effective intraperitoneal chemotherapy with mild side effects for advanced rectal cancer.

The overactive bladder syndrome (OAB) is a prevalent condition among adults. Currently, the present treatment is mainly conservative therapy. Antimuscarinic drugs are currently the first-line treatment for OAB. However, many patients experienced insufficient therapeutic benefit and/or unpleasant side effects. Recent advances in the understand-ing of the physiopathology of OAB have driven a huge amount of basic and clinical research into novel pharmacological com-pounds.β3-adrenoceptor agonists are an emerging drug class for the treatment of the OAB. This study reviewed the pharma-cological profile ofβ3-adrenoceptor agonists and discussed the efficacy, safety and tolerability.
