Chinese Journal of cardiovascular Rehabilitation Medicine 2017;26(2):214-216
Objective: To study effect of comprehensive nursing on patients with arrhythmia after acute myocardial infarction (AMI).Methods: According to random number table, a total of 100 patients with arrhythmias after AMI were selected in our hospital, and randomly and equally divided into routine nursing group and comprehensive nursing group (received comprehensive nursing based on routine nursing).NYHA cardiac function class, incidence rate of arrhythmia, standard reaching rate of health knowledge, mean bed time, mean length of hospital stay, mean hospitalization fee and satisfaction were compared and analyzed between two groups after treatment.Results: Compared with routine nursing group after treatment, there was significant rise in percentage of NYHA class I (24% vs.54%), and significant reductions in percentages of NYHA class III (38% vs.12%) and IV (10% vs.4%),P<0.05 or<0.01;significant reductions in incidence rate of arrhythmia (64% vs.12%), mean bed time[(5.01±0.63) d vs.(2.88±0.65) d], mean length of hospital stay[(16.15±2.00) d vs.(10.00±1.22) d]and mean hospitalization fee[(6984.95±652.30)RMB vs.(5274.95±632.30)RMB], and significant rise in standard reaching rate of health knowledge (72% vs.96%) and treatment satisfaction (80% vs.96%) in comprehensive nursing group, P<0.05 or<0.01.Conclusion: Comprehensive nursing can effectively improve therapeutic effect and shorten length of hospital stay in patients with arrhythmia after acute myocardial infarction, and it is worth extending.

3.Nicotinic acetylcholine receptor and clinical diseases
Basic & Clinical Medicine 2006;0(05):-
Nicotinic acetylcholine receptors(nAChRs) construct a family of ligand-gated ion channels. nAChRs distribute extensively in central nerve system, neuromuscular junctions and surface of other cells. The differences on subunits and tissue location determinate the diversity of receptor functions. Early research has found that nerve signal transmission is its main function and recent research found it also the key receptor of cholinergic anti-inflammatory pathway. To illuminate the physiological mechanism of these functions has great clinical significance for the treatment of correlated diseases such as myasthenia gravis, epilepsy and multiple organ failure.

Objective To investigate the effects of oral glucose-electrolyte solution (GES) on resuscitation of hemorrhagic shock induced by 40% blood volume loss in rats. Methods SD rats were randomly divided into three groups; oral GES without hemorrhagic shock (GES group, n = 16) , hemorrhage shock without fluid resuscitation (HS group, n = 20) and hemorrhagic shock resuscitated with oral GES (HS + GES group, n = 20). About 40% of total blood volume was bled from carotid artery of rats to produce a model of hemorrhagic shock. GES with a volume of three times of blood loss was given three times intragastrically at 0.5, 1 and 6 hours after hemorrhage. Mean arterial pressure (MAP) was measured constantly. Blood flow in liver, kidney, stomach and small intestines, and parameters like hemato-crit, plasma osmotic pressure, alanine aminotransferase (ALT) , creatinine (Cr) and diamine oxidase (DAO) were determined 24 hours after hemorrhage. Survival rates of the rats in three groups were calculated 24 hours after hemorrhage. Results MAPs of HS + GES group were 9. 7% and 10. 9% higher than those of HS group 4 and 24 hours after hemorrhage (P < 0. 05). The blood flow of liver, stomach and small intestines in HS + GES group were 18.6% , 88.4% and 22.0% respectively, higher than those in HS group(P <0.05 or P <0.01) 24 hours after hemorrhage. The hematocrit level of HS + GES group was significantly lower than that of HS group, while the levels of ALT, Cr and DAO in HS + GES group were significantly lower than those in HS group (P <0.01). The survival rate of rats in HS + GES group was 80% , which was significantly higher than 30% in HS group (P <0.01). Conclusions Oral rehydration can significantly improve MAP and tissue perfusion, maintain blood volume and plasma osmotic pressure, alleviate organ damage and hence promote the survival rates of rats with hemorrhagic shock.

Objective To investigate the effects of carbachol on intestinal inflammation and mucosal blood flow after gut ischemia-repedusion(I/R) in rat. Method A jejunal sac was formed in Wistar rats. The superior mesenteric artery (SMA) was occluded for 45 mi-nutes followed by 240 minutes of reperfusion. Animals were random divided into three groups: sham operation, L/R + saline injection (I/R + NS) and I/R + carbachol injection (0.1mg/kg, I/R + Ca). Immediately after occluded of SAM blood flow, either 0.1mg/kg of carba-chol or same account of 0.9% saline was injected into the jejunal sac. The pathological injury was observed with HE staining. The activity of DAO and content of TNF-α in intestinal mucosa tissue were determined. Mucosal blood flow was measured by laser Doppler. All measure-ments were done at 0 min, 30 min, 60 min, 120 min, and 240 min after reperfusion. Result In I/R group the activity of DAO in intestinal mucosa and mucosal blood flow deceased, meanwhile the content of TNF-α gut tissue was dramatically increased than those in sham operation (P<0.01). Severe pathological changes were observed in intestinal mucosa. After injection of carbachol, the activity of DAO and mucosal blood flow increased (P<0.01), but the content of TNF-α in intestinal mucosa were dramatically decreased (P<0.01), compared with those in I/R group. Conclusion Administration of carbachol protects intestinal ischemia-reperfusion injury by attenuating intestinal mucosa inflammation and increasing gut mueosal blood flow.

Objective To study the relationship between polymorphisms of NQO1 and hepatocellular carcinoma (HCC) in Zhengzhou and Guilin area.Methods The Zhengzhou group was a hospital-based case-control study which included 146 cases of HCC and 151 cases of controls with nontumor seen in the People's Hospital of Zhengzhou.The Guilin group was a hospital-based case-control study which included 136 cases of HCC and 123 cases of controls with non-tumor seen in the Guilin Medical University Hospital.NQO1 polymorphisms were determined by polymerase chain restriction with TaqMan MGB probe.All data were analyzed by conditional logistic multiple factor regression analysis with SPSS 18.0 statistical package.Results The frequency with mutation allele (T) in the case group was significantly different between the Zhengzhou and Guilin groups (x2=23.307,P< 0.05).The odds risk of NQO1 mutation homozygote and mutation heterozygote to wild homozygote were significantly increased (OR=2.476,CI:1.518~4.038).Conclusions NQO1 mutation genotype is the predisposing gene with relatively different susceptibility to the development of HCC in the Zhengzhou and Guilin regions.There are synergistic effects between the NQO1 predisposing genotype,drinking and smoking.
