Sixty patients with dysphagia following the acute stroke were enrolled and divided into training group and control group with 30 cases in each group.Both groups received the routine medication,but patients in training group had additional swallowing rehabilitation training.After 4 weeks,the recovery rate of swallowing function in training group was higher than that in control group [ 93 ％ (28/30) vs.63 ％(19/30),P ＜ 0.05 ] ; the incidence rate of aspiration pneumonia in training group was lower than that in control group[ 3.3％ ( 1/30 ) vs.26.7％ ( 8/30 ),P ＜ 0.05 ].The results showed that swallowing training applied to acute stroke patients with dysphasia may promote the recovery of swallowing function,reduce the complications and improve their quality of life.

Objective To discuss the best way of gastric lavage in patients with drug intoxication.Methods Patients with drug intoxication(128 cases)were divided into the observation group(68 cases)and the control group(60 cases).The observation group adopted modified method,left lateral decubitus without pillow,plastic mouth-gap to assist intubation,the tube Was prolonged 10 to 15 cm after successful intubation,then repeated gastric lavage with little lavage liquid was carried out under low pressure.The control group was treated with routine method.One-time success rate of intubation,the incidence of adverse reaction and complications were observed and compared between the two groups.Results One-time success rate of intubation was higher,and the incidence of adverse reaction and complications were lower in the observation group compared with those of the control group.Conclusions The modified gastric lavage method,that is,left lateral decubitus without pillow,plastic mouth-gap to assist intubafion,the tube was,prolonged 10 to 15 cm after successful intubation,then repeated gastric lavage with little lavage liquid,is better than the routine method in the following aspects,higher one-time success rate of intubation,rapid gastric lavage,patency of drainage,little stimulation and injury of gastric mucosa,light adverse reaction and complication and better lavage effect.

Objective To observe the clinical curative effect of edaravone on treatment of acute lagre area cerebellar irdarction(ALACI). Methods 31 ALACI patients attacked within 72h were randomly assigned to therapygroup( n = 16) and control group( n = 15). Therapy group took the basic treatment as well as edaravone infused at a dose of 30mg,twice a day for 14 days. Control group took similar treatment to therapy group expect for edaravone.At 0th ,7th, 14th ,21th day after treatment, the C.SS and ability of daily living(ADL) were used to evaluate the recovery of neurological functions. Results Significant difference of CSS and ADL grading were detected between therapygoup and control group at 7th, 14th day( P < 0.05 ), with lower grading in therapy group ; there were significant differ-ence of CSS and ADL grading between therapy goup and control group at 21th day( P < 0.01 ), with lower grading in therapy group. No evident side effect was detected in edaravone therapy group. Conclusion Edaravone is a safe a-gent. It can effectively improve the neurological deficits and daily living ability of ALACI patients.

BACKGROUND: Functional hydrogel Is a new biomaterial, which considered as wound dressing should be generally evaluated according to biological standard to prove the great biocompatibility prior to clinical application.OBJECTIVE: To evaluate the biocompatibility of a new kind of wound dressing, polyvinyl alcohol-gelatin esterified (PGE) hydrogel.DESIGN, TIME AND SETTING: A materials study was performed at Central Laboratory, College of Public Health, University of South China from April 2008 to June 2009.MATERIALS: Fibroblast strain of NCTC L-929 mice was provided by Medical College of Sun Yat-sen University; experimental animals were provided by Animal Faulty of Southern China University; polyvinyl alcohol and gelatin were provided by Chemical Agent Engineering Developing Center, Guangdong.METHODS: A 10-g polyvinyl alcohol was generally dissolved in 100 mL water and the mixture was added with 5 g gelatin at 70 °C. Additionally, hydrochloric acid was added and fully stirred for esterification reaction. The dispersion solution was inserted into the tooting and transformed into membrane-like products which were sectioned into 1-mm round and thin sections. Toxicity test, hemolytic test, and whole-body acute-term toxicity test, and sensitization test of PGE were performed according to national GB/T16886 standard.MAIN OUTCOME MEASURES: Biocompatibility of PGE hydrogel.RESULTS: Toxicity reaction of PGE hydrogel was grade 0-1, and hemolytic ratio was 5%. Following an injection of PGE hydrogel, mice did not have death, convulsion, paralysis, respiratory depression, diarrhea, and decreased body mass. Seventy-two hours later, erythema and edema were not observed on both sides of spine of mice.CONCLUSION: The PGE hydrogel has a good biocompatibility and can be used for wound dressing on clinic.

Objective To observe the efficacy and safety of BiPAP ventilator combined with nikethamide for the chronic obstructive pulmonary disease (COPD)complicated with type II respiratory failure.Methods 76 COPD patients complicated with type II respiratory failure were selected as the research subjects,they were randomly divided into two groups by single blind and randomized method,38 cases in each group.The control group was treated with nikethamide therapy,while the observation group used BiPAP combined with mechanical ventilation therapy.The clinical therapeutic effect and adverse reactions were analyzed and compared in the two groups.Results The total effective rate in the observation group was 92.11%,which was significantly higher than 68.42% in the control group (χ2 =10.54,P <0.05).After treatment,the HR and RR of the observation group were (94.28 ±7.62)/min, (13.27 ±4.41)/min,which were significantly decreased than before treatment (t =8.02,8.04,all P <0.05),and which were significantly lower than those in the control group (t =7.54,6.88,P <0.05).After treatment,the pH (7.39 ±0.06),PaO2 (96.31 ±5.44)mmHg,SaO2 (98.42 ±6.87)% in the observation group were significantly increased (t =7.56,7.76,7.45,all P <0.05),PaCO2 (57.36 ±4.98)mmHg was significantly decreased (t =7.54, P <0.05),which had significant differences with the control group (t =6.56,7.02,6.73,7.32,all P <0.05).There was no significant difference in the incidence of adverse reactions between the two groups (χ2 =2.14,P >0.05). Conclusion BiPAP ventilator combined with nikethamide meters has remarkable curative effect and high safety in treatment of COPD patients complicated with type II respiratory failure,which is worthy of clinical reference and popularization.
