Objective To investigate the therapeutic effect of acupuncture combined with Vitalstim electric stimulation therapy for treatment of patients with dysphagia after ischemic stroke.Methods Ninety-two patients with dysphagia after ischemic stroke in accord with the criteria of enrollment in this study were admitted to the Department of Acupuncture of the First Affiliated Hospital of Tianjin Traditional Chinese Medicine University from May 2014 to November 2016, and they were divided into a control group and an observation group by random number table, 46 cases in each group. Both groups were treated with stroke conventional drug therapy and feeding swallowing rehabilitation training, in addition, Vitalstim swallowing therapeutic electrical stimulation therapy was used in the control group, and acupuncture combined with Vitalstim stimulation were applied in observation group. The changes of swallowing ability score, video fluoroscopic swallowing study (VFSS) score and adverse reactions were observed before and after treatment in the two groups, and the curative effect of combined method was evaluated.Results Compared with those before treatment, the swallowing ability and VFSS score of two groups after treatment were obviously higher, and the degrees of changesin observation group were more significant than those in control group (swallowing score: 8.12±1.13 vs. 7.45±1.04, VFSS score: 7.97±1.05 vs. 5.67±0.88, allP < 0.05); the total efficiency in the observation group was markedly higher than that in the control group [95.7% (44/46) vs. 78.3%(36/46)], the adverse reactions (wrong aspiration, pulmonary infection) in the observation group were significantly lower than those in the control group [10.9% (5/46) vs. 28.3% (13/46)], and there were statistically significant differences between the two groups (bothP < 0.05).Conclusions Acupuncture combined with Vitalstim electric stimulation therapy can improve the swallowing ability in patients with dysphagia after ischemic stroke, and the therapy has less adverse reactions; compared with the simple Vitalstim electric stimulation therapy, in the aspect of improving swallowing ability, the therapeutic effect of combined therapy is more significant.

Background Retinal ischemia/reperfusion injury is a common pathological process in ophthalmology.It can cause permanent visual impairment.The prevention and treatment of retinal ischemia/reperfusion injury is one of the focus topics at home and abroad up to now.Objective Present study was to evaluate the protective effects of geranylgeranylacetone(GGA)on retinal ischemia/reperfusion injury.Methods The retinal ischemia/reperfusion models were established in 40 SD rats by the infusion of normal saline solution into the anterior ehamber to elevate the intraoeular pressure for 1 hour and then remove the process.GGA of 2 ml (800 ms/kg)was intragastrieally administered in 20 model rats as GGA group,and the equal volume of normal saline solution was used at the same way in other 20 models as model group.Four normal matched SD rats were served as normal control group.The histological changes of retina in 6,24,48,72 hours after modeling was examined by hematoxylin-eosin staining under the light microscope.and the expression of heat shock protein 70(HSP70)and caspase-3 in retina at the time points mentioned above was detected by immunohistochemistry.Results The edema of cornea and retina of rats appeared in 1 hour and peaked in 24 hours after modeling.In 72 hours after modeling,the edema was alleviated but the disorder of retina structure was found in model group.However,although the pathological change process was similar to that of model group,the damage of retina tissue was milder in the rats of GGA group under the light microscope.HSP70 and caspase-3 were absent in the retina of normal rats.But。The expression of HSP70 in retinal ganglion cells(RGCs)was found in 6 hours after modeling,reached peak in 24 hours and declined after that in model group.The numbers of positive cells for HSP70 in retina was significantly increased in various time points in GGA group,showing statistically significant differences between model group and GGA group(P<0.05).In model group,a few of caspase-3 positive cells were found 6 hours after reperfusion and increased gradually until reaching the peak 24 hours and then decreased gradually 48 hours later.Few caspase-3 positive cells were found 72 hour8 after reperfusion.The numbers of positive cells for caspase-3 decreased in GGA group compared with model group during the experimental duration with the considerable difference between these two groups(P<0.05).Conclusion GGA could protect RGCs against isehemia/reperfusion injury by upregulating the expression of HSP70 and downregulating the expression of caspase-3 in retina.

Objective To analysis the relation between diet,physical activities and chronic disease.Methods Collecting and analyzing the data of 3 673 Tianjin residences selected randomly as sample in 2002 China National Health and Nutrition Examination Survey.Dietary pattern and prevalence of chronic diseases were obtained,as well as the relative risk of diet,physical activities on chronic diseases including obesity,hypertension,diabetes and hyperlipidemia.Results The prevalent rates in Tianjin adults were 26.8% for obesity,3.07% for hypertension,32.2% for hyperlipidemia and 3.7% for diabetes.Main dietary problems among them were higher intake of oil and salt,lower intake of vegetable and fruit.The percentages of energy from fat ≥30% and watching TV≥3 hours/d were risk factors for overweight/obesity,hypertension,diabetes and hyperlipidemia with OR values as 2.04(95%CI:1.53～3.04),2.00(95%CI:1.13～3.57),2.22(95%CI:1.66～2.98),1.64(95%CI:1.18～2.31);1.89(95%CI:1.32～2.70),1.79(95%CI:1.48～2.16),1.47(95%CI:1.33～1.78)and 1.45(95%CI:1.28～1.65).Physical exercises ≥30 minutes /d was a protective factor for those four chronic diseases with OR values as 0.42(95%CI:0.28～0.68),0.60(95%CI:0.40～0.89),0.50(95%CI:0.35～0.80),0.61(95%CI:0.44～0.93)respectively.Intake vegetable and fruit ≥500 grams /d could reduce the risk for obesity and hyperlipidemia,OR values were 0.60(95%CI:0.40～0.89)and 0.47(95%CI:0.30～0.72).Conclusion There was a strong relation between diet,physical activities and chronic diseases in Tianjin sampled people.It should strengthen health promotion with balanced diet and good physical activity for the chronic diseases prevention.

Objective To analyze the relationship between life style and chronic diseases.Method 2 886 people were selected randomly from three districts of Tianjin and surveyed with a questionnaire on their healthy condition and physical examination.2 622 people were taken a diet survey by 3-days foods intakes weighing and 24-hours diet recall,then the relative risk factors between life style and coronary heart disease,cerebrovascular disease,diabetes,hypertension,overweight and obesity were analyzed.Result The standardized prevalence rates of coronary heart disease,cerebrevascular disease,diabetes,hypertension, overweight and obesity of residents were 9.24%,4.33%,6.74%,34.05%,and 42.62%,respectively.The more the intake of energy, the more the risk for people to suffer from overweight and obesity,OR value being 1.00-1.70.With intake of more than 20 g dietary fiber per day,the risk for suffering from overweight and obesity could be reduced,OR value being 0.68.Logistic analysis showed that heavy salty taste could increase the risk for suffering from hypertension by 42%.Watching TV more than 3 hours per day increased the risk for suffering from cerebrovascular disease and diabetes,OR value being 1.802 and 1.703 respectively.Sleep less than 7 hours per day was a dangerous factor for hypertension,coronary heart disease and cerebrovasular disease,OR value being 1.517, 1.833 and 2.041 respectively.Conclusion The life style such as dietary pattern,sedentary occupation and sleep hours have strong connection with chronic diseases,such as hypertension,diabetes etc.Reasonable diet,suitable exercises,reducing sedentary position and increasing sleep hours will be good for health,and also for the prevention and control of chronic diseases.

Objective To compare the clinical efficacy between reformed laparoscopic-assisted vaginal hysterectomy with sutureless of cardinal and uterosacral ligament(LAVH)and trans abdominal hysterectomy(TAH)for large uterus.Methods A retrospective study was performed using 106 reformed LAVH patients(observation group)and 100 TAH patients(control group)whose uterus were big(≥ 12weeks of gestation),the information was observed in perioperative period.Results Anal exsufflation time,hospitalization time after operation and postoperative pain time in observation group[(25.4 ± 3.3)h,(6.5 ±1.5)d,(16.9 ± 2.4)h]were significantly shorter than those in control group[(42.4 ± 5.3)h,(8.5 ± 1.5)d,(30.6 ± 5.3)h](P ＜ 0.05),the rate of complication in observation group[5.7％(6/106)]waa lower than that in control group[10.0％(10/100)](P＜ 0.05).Conclusion As to large uterus,reformed LAVH has several advantages over TAH,the technique is easy to learn,operation time is short,and the rate of complication is low.

Objective To investigate the autonomic modulation and influence during myocardial ischemia based on analysis on heart rate dynamics with heart rate variability(HRV). Methods From 13 free download ECG records in long-term ST-T(LTST)database, 193 ischemia episodes were extracted for analysis, and 5 min intervals before and after each selected isehemia episode were selected as control ones. Using symbolic dynamic analysis method, the indexes during different stages were calculated. The repeated measurement analysis of variance was introduced for statistic test. And the distribution of autonomic reflex mode to isehemia duration was analyzed by linear fitting. Results Symbolic analysis detected an increase in the percentage of non-varlable patterns (0 V%) and a decrease in the percentage of very variable patterns(2 UV%), indicating a more sympathetic predominance compared with the baseline. But the trend of the shift in autonomic balance towards sympathetic predominance reduced with the extension of ischemic duration, suggesting a possible protection for heart. Conclusion Symbolic dynamic analysis is capable of identifying changes in autonomic modulation and seems appropriate for elucidating the neural pathophysiological mechanisms occurring in myocardial ischemic episodes.

Objective To investigate the effects of ischemic postconditioning on mitochondrial permeability transition and mitochondrial transmembrane potential(△Ψm)following hepatic ischemia-reperfusion(I/R)in rats.Methods Forty male SD rats weighing 220-260 g were randomly divided into 5 groups with 8 animals in each group:sham operation group(group S);atractyloside+sham operation group(group A+S);I/R group;ischemic postconditioning group(group IPO)and atractyloside+ischemic postconditioning group(group A+IPO).The animals were anesthetized with intramuscular injection of atropine 0.05 mg/kg.Hepatic I/R was produced by occlusion of hepatic blood flow for 60 min followed by 6 h reperfusion.In group A+S,atractyloside 5 mg/kg was injected intravenously before abdomen Was closed.In group IPO,the animals were subjected to 3 cycles of 1 min reperfusion interspersed with 1 min hepatic isehemia at the end of 60 min hepatic ischemia.In group A+IPO,atractyloside 5 mg/kg was injected intravenously before reperfusion. Venous blood samples were collected for determination of serum ALT and AST activities immediately before ischemia and at 6 h of reperfusion. The animals were then sacrificed.Their livers were removed for microscopic examination, detection of apoptosis and determination of cytochrome c (Cyt c) expression, △Ψm and mitochonerial permeability transition pore (MPTP)activity. Apoptosis index (AI) was calculated. Results There was no significant difference in serum ALT and AST activities, AI, Cyt c expression, △Ψm and MPTP activity between S and A + S groups (P＞0.05). Compared with group S, serum ALT and AST activities and AI were significantly increased, Cyt c expression was up-regulated, △Ψm was decreased and MPTP activity was increased in groups I/R, IPO and A+IPO(P＜0.05).Compared with group I/R, serum ALT and AST activities and AI were significantly decreased,Cyt c expression was down-regulated, △Ψm was increased and MPTP activity was decreased in group IPO(P＜0.05), while no significant change was found in group A+IPO(P＞0.05).Compared with group IPO,serum ALT and AST activities and AI were significantly increased, Cyt c expression was up-regulated, △Ψm was decreased and MPTP activity was increased in group A + IPO(P＜ 0.05).Microscopic examination showed that hepatic injury was reduced in group IPO compared with group I/R, while aggravated in group A+ IPO compared with group IPO. Conclusion Ischemic postconditioning can protect liver from I/R injury by attenuating the I/R-induced increase in MPTP opening and decrease in △Ψm in rats.
