Objective To investigate differences of teaching effects between CAI method and traditional teaching method. Methods The performance records of material media were compared after the students of nursing specialty attended lectures with CAI method or traditional teaching method. Results Comparing CAI method with traditional teaching method, there are respective advantages. CAI method and traditional teaching method can not substitute each other. Conclusions Effect of teaching with combination of CAI method and traditional teaching method has more advantage than simple CAI method.

Objective To study the clinical therapeutic effects of early rehabilitation training combined with acupuncture on dysphagia after acute cerebral infarction.Methods One hundred patients with dysphagia caused by acute cerebral infarction were randomly divided into 4 groups:a comprehensive treatment group(25 cases,received rehabilitation training,acupuncture and routine medication),a routine drug group(25 cases,routine medication),a rehabilitation group(25 cases,received comprehensive rehabilitation training and routine mediciation)and an acu-puncture group(25 cases,received acupuncture therapy and routine medication).Dysphagia was evaluated with videofluoroscopic swallowing study(VFSS),and the incidence of pneumonia was observed before treatment and at the 14th day after daily treatment. Results After treatment,the VFSS scores of the 4 groups were significantly higher than before treatment,and VFSS scores in the comprehensive treatment group were significantly higher than those in the other groups.The effectiveness rate in the comprehensive treatment group was significantly higher than that in the other three groups.and the incidence of pneumonia was significantly lower.Conclusions Early rehabilitation com-bined with acupuncture can improve swallowing and reduce the incidence of aspiration pneumonia in acute stroke pa-tients.

Objective To study the effects of angiotensin Ⅱ(AngⅡ) on cardiac cAMP accumulative levels induced by isoprenalin(Iso) and AngⅡ on positive inotropic response induced by Iso stimulation ?-adrenoceptor (?-AR) in 3.5- and 12.0- months-old rats. Methods Radioimmunoassay and functional experiment of isolated left atrias were applied to measure the levels of cAMP and cGMP and the positive inotropic response in the hearts. Results Iso increased cAMP accumulation in 3.5-month-old rats〔(1 027?169)pmol/mg vs (1 400?267)pmol/mg,P

Objective To evaluate the role of endogenous heme oxygenase-1/carbon monoxide ( HO-1/CO) signaling pathway in endoplasmic reticulum stress during endotoxin-induced acute lung injury ( ALI) in rats. Methods Forty healthy clean-grade male Sprague-Dawley rats, aged 8 weeks, weighing 190-210 g, were divided into 4 groups ( n=10 each) using a random number table method: control group (group C), ALI group, ALI plus ZnPP-IX group (group AZ), and ALI plus vehicle sodium bicarbonate group ( group AV) . ALI was induced by intravenously injecting lipopolysaccharide 5 mg/kg in anesthetized rats. At 30 min before establishing the model, ZnPP-IX 10μmol/kg (diluted to 1 ml in 50 mmol/L sodium bicarbonate) was intraperitoneally injected in group AZ, and 50 mmol/L sodium bicarbonate 1 ml was intra-peritoneally injected in group AV. After injecting lipopolysaccharide for 6 h, blood samples were collected from the common carotid artery for determination of plasma CO concentration, the rats were then sacrificed, and lungs were removed for microscopic examination of the pathological changes which were scored and for determination of CO level, wet to dry weight ratio ( W/D ratio) , cell apoptosis ( by TUNEL) , and expres-sion of heme oxygenase-1 ( HO-1) , glucose-regulated protein 78 ( GRP78) , phosphorylated protein kinase R-like endoplasmie reticulum kinase (p-PERK), phosphorylated eukaryotic translation initiation factor 2 alpha ( p-elF2 ) , CCAAT/enhancer-binding protein homologous protein ( CHOP ) and caspase-12 in lung tissues ( by Western blot) . Apoptosis index ( AI) was calculated. Results Compared with group C, the lung injury scores, W/D ratio, AI and CO levels in plasma and lung tissues were significantly increased, and the expression of HO-1, GRP78, p-PERK, p-elF2, CHOP and caspase-12 was up-regulated in the other three groups ( P＜0. 05) . Compared with group ALI, lung injury scores, W/D ratio and AI were sig-nificantly increased, CO levels in plasma and lung tissues were decreased, the expression of HO-1 was down-regulated, and the expression of GRP78, p-PERK, p-elF2, CHOP and caspase-12 was up-regula-ted in group AZ (P＜0. 05), and no significant change was found in the parameters mentioned above in group AV ( P＞0. 05) . Conclusion HO-1/CO signaling pathway produces endogenous protection possibly through inhibiting endoplasmic reticulum stress during endotoxin-induced ALI in rats.

Objective To investigate the risk factors and MRA manifests in the patients with cortical wa-tershed infarcts(CWSI)or internal watershed infarcts(IWSI).Methods We collected the patients with acute wa-tershed infarcts in our hospital from January 2013 to April 2016.According to the Bogousslavsky classification stan-dard,the patients were divided into two groups:CWSI and IWSI. The two groups were compared in terms of risk factors and MRA manifests. Results We included 36 CWSI and 11 IWSI patients in the study.There were signifi-cant differences in smoke,diabetes mellitus,fasting blood glucose levels and carotid atherosclerotic plaque be-tween the two groups,and so it was with the stenosis of ICA,MCA,ACA,PCA,VA and BA:The stenosis of ICA in the CWSI group was more serious than in the IWSI group,but the stenosis of MCA,ACA,PCA,VA and BA in the IWSI group was more serious than in the CWSI group. Conclusions The pathogenesis of CWSI may be related to the formation of carotid atherosclerotic plaques,carotid stenosis and arterial artery embolism,or plaque shedding and micro emboli removal.The pathogenesis of IWSI may be related to the decrease of the perfusion pres-sure at the end of the intracranial artery.The ratio of IWSI to diabetes mellitus is higher than that of CWSI,suggest-ing that the damage of diabetes to intracranial arteriole is earlier than that of intracranial and extracranial arteries.

The clinical data of patients with severe acute pancreatitis complicated with intraabdominal hypertension or abdominal compartment syndrome admitted to our Department of Critical Care Medicine from January 1, 2018 to October 1, 2021 were collected and analyzed.Patients were divided into a conventional treatment group and conventional treatment plus IV infusion of cisatracurium besilate group (muscle relaxation group). A prediction model of treatment propensity score was developed for paired screening, with 31 cases in each group.The conventional treatment group adopted conventional basic treatment methods such as gastrointestinal decompression, spasmolysis and analgesia, fluid therapy, inhibition of gastric acid, suppression of parenzyme, nutritional support, mechanical ventilation, and enemata.In muscle relaxation group, cisatracurium besilate was intravenously infused on the basis of routine treatment with the initial dose of 0.15 mg/kg given to facilitate endotracheal intubation, followed by continuous intravenous infusion at 1-3 &mu;g·kg -1·min -1, and the dose was adjusted according to the patient′s basic vital signs and clinical effects.The primary outcome was survival rate.Secondary outcome measures were changes in intraabdominal pressure, oxygenation index, the number of defecation, volume of defecation, and urination volume before treatment and on 7, 14 and 20 days of treatment.and the recovery time of bowel sounds, length of mechanical ventilation, time of intensive care unit treatment, and total hospitalization costs.Compared with conventional treatment group, the survival rate was significantly increased, the intraabdominal pressure was decreased on 7, 14 and 20 days of therapy, the oxygenation index was increased, the number of defecation and volume of defecation were increased on 7 and 14 days of therapy, urinary volume was increased before treatment and on day 7 of therapy, the recovery time of intestinal sound was significantly shortened ( P<0.05), and no significant change was found in urinary volume on days 14 and 20 of therapy, length of ventilation, time of intensive care unit treatment, and total hospitalization costs in muscle relaxation group ( P>0.05). In conclusion, cisatracurium besilate can improve oxygenation, promote the recovery of intestinal function and improve the survival rate when used to assist the treatment in the patients with severe acute pancreatitis complicated with intraabdominal hypertension.
