Objective To investigate the clinical features of aged patients with acute hemorrhage arising from vascular malformation of colon and the efficacy of endoscopic placement of hemoclip in treatment of hemorrhage. Methods Fifty-six patients were diagnosed with acute bleeding arising from vascular malformation of colon by colonoscopy. Patients were assigned to aged group (n = 31,≧60 years of age) and control group (n = 25, <60 years of age). The clinical manifestations and the efficacy of emergent endoscopic treatment with hemoclip application were compared between two groups. Results The complications including hypertension, coronary heart disease and diabetes were higher in aged group [80. 6% (25/31)] than in control group [40. 0% (10/25) ] with significant difference (P<0. 01). The effusive bleeding accounted for 45. 2% (14/31) in aged group and 16. 0% (4/25) in control group (P<0. 05). Endoscopic treatment with hemoclip was performed in 18 and 6 patients in aged group and control group, respectively. Initial hemostasis was achieved in 17 and 6 patients in the aged group and control group, respectively (P<0. 05). Recurrent hemorrhage occurred in 2 patients in the aged group and none in the control group (P>0. 05). The mean number of hemoclips application was 5. 3 ± 2. 4 in aged group and 3. 1 ± 1. 3 in control group (P<0. 05). Conclusions The hemorrhage is more serious in aged patients with acute hemorrhage, because they often complicate with cardiovascular diseases and diabetes. The lesion of hemorrhage can be found and precisely localized using colonoscopy. Promptly endoscopic placement of hemoclip is quite effective in treatment of acute hemorrhage.

Objective To investigate the influence of follow-up treatment compliance on prognosis after gastroesophageal varices treated under endoscopy.Methods Up to 416 liver cirrhosis patients after gastroesophageal varices treated under endoscopy were follow-up and divided into compliance group and control group according to whether the patients had follow-up treatment compliance condition.The factors caused the difference of follow-up treatment compliance were analyzed.The differences in the follow-up indexes such as rebleeding,mortality,rehospitalization were compared between the two groups.The differences in indexes between two groups were stratifiedly analyzed according to liver function Child-Pugh classification.Chi-square four data table test was for two independent samples comparison.Results The differences of education level,income and the medical condition of residential area determined the difference of follow-up compliance.After gastroesophageal varices patients treated under endoscopy,the total rebleeding rate was 35.1 ％ (146/416) and and the mortality rate was 9.4％ (39/416).The rebleeding rate and mortality rate of the compliance group were significantly lower than those of control group (26.1％ (61/234) vs 46.7％(85/182),x2=19.137,P＜0.01; 6.4％(15/234) vs 13.2％(24/182),x2=5.533,P=0.019).Among the 273 Child-Pugh A level patients,the detection rate of liver cancer (3.7％,10/273),liver transplantation rate (3.7％,10/273),splenectomy plus portal azygous disconnection rate (6.6％,18/ 273) of compliance group were higher than those of control group (x2 =4.086,P =0.043; x2 =4.086,P=0.043; x2 =5.515,P=0.019).Among the 102 Child-Pugh B level patients,there were statistical differences between compliance group and control group in rebleeding rate (x2 =21.297,P＜0.01),motality (x2=3.525,P=0.042),ascites (x2=4.451,P=0.035),life quality (x2 =10.454,P=0.001) and liver function (x2 =8.197,P=0.004).However,there were no statistical differences in all indexes between the two groups of Child-Pugh C level patients (all P＞0.05).Conclusion To improve the follow-up treatment compliance remarkably,decreased the rebleeding rate and mortality,contributed to early detection of liver cancer and early liver transplatation,thus the prognosis was improved consequently.

OBJECTIVETo observe the clinical efficacy of deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training for post-stroke dysphagia.

METHODSSixty cases of post-stroke dys phagia were randomly divided into an observation group and a control group, 30 cases in each one. Patients in the observation group, based on the regular acupuncture treatment, were treated with deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17), once a day, 30 min per treatment; also swallowing training was combined, twice a day, 20 min per treatment. Patients in the control group were treated with swallowing training. All the patients were treated with regular treatment of stroke. Six days of treatment were taken as one session, and totally 3 sessions were given with an interval of one day between sessions. The video fluoroscopic swallowing study (VFSS) dysphagia evaluation scale and Watian water swallow test (WWST) were evaluated before and after treatment also the clinical efficacy and the recovery time of two groups were compared.

RESULTSAfter treatment, the VFSS score in the observation group was significantly superior to that in the control group (P < 0.01); the WWST in the observation group was significantly superior to that in the control group (P < 0.01). The cured rate was 70.0% (21/30) in the observation group, which was significantly superior to 43.3% (13/30) in the control group (P < 0.01); the total effective rate was 86.7% (26/30) in the observation group, which was significantly superior to 66.7% (20/30) in the control group (both P < 0.01). The clinical recovery time in the observation group was significantly shorter than that in the control group (P < 0.01).
