[ Method] Dairy cattle with retained placenta were treated with oral administration of Yizhikang powder. And their hemorheological indexes were measured and compared with the corresponding indicators of pre-administration group, healthy group, and control group （sick but untreated）.[ Result] There was large decrease amplitude in the indexes （whole blood viscosity, plasma viscosity, whole blood viscosity reduction viscosity, ESR, ESR equation K value, fibrinogen content, platelet aggregation rate, RBC deformability IF value） of treated dairy cattle with retained placenta. By t test, the indexes, except hematocrit, decreased significantly after treatment （P〈0.05） and reached the status of post partum healthy cows. The hemorheological indexes didn＇t change significantly in the control group before and after treatment. [ Conclusion] Yizhikang powder could significantly improve blood flow state and reduced the occurrence of qi stagnation and blood stasis in perinatal period.展开更多

METHODS：Twenty-nine consecutive patients with acute massive bleeding of duodenal ulcer were admitted to our hospital from 2006 to 2011. Superselective angiography of the celiac and gastroduodenal arteries was performed to find out the bleeding sites before ETAE, then, embolotherapy was done with gelatin sponge particles or microstrips via a 5 French angio-graphic catheter or 3 French microcatheter. After ETAE, further superior mesenteric arteriography was under-taken in case collateral circulation supplied areas of the duodenal ulcer. Technical and clinical success rates were analyzed. Changes in the mucous membrane were observed using endoscopy following ETAE. RESULTS：Angiography showed active bleeding with extravasation of contrast medium in seven cases with a 24% positive rate of celiac artery bleeding, and in 19 cases with a 65.5% rate of gastroduodenal artery bleeding. There were no angiographic signs of bleeding in three patients who underwent endoscopy prior to ETAE. Twenty-six patients achieved immediate hemostasis and technical success rate reached 90%. No hemostasis was observed in 27 patients within 30 d after ETAE and clinical success rate was 93%. Recurrent hemorrhage occurred in two patients who drank a lot of wine who were treated by a second embolotherapy in the same way. Five patients underwent transient ischem with light abdominal pain under xiphoid, spontaneous restoration without special treatment. No mucous necrosis happened to 29 cases for ischem of gastroduodenal arteries embolized. CONCLUSION：ETAE is an effective and safe measure to control acute massive bleeding of duodenal ulcer.展开更多

All gastroduodenal ulcer and cardiovascular events occurred were recorded and the patients were followed up for 1.5 years after treatment. At the end of the trial, a systematic interview survey about other adverse events was conducted. RESULTS: Gastroduodenal ulcer was detected in 19 of 463 (3.72%) patients who received celecoxib and 17 of 473 (3.31%) patients who received placebo, respectively (odds ratio = 1.13, 95% CI = 0.58-2.19). Cardiovascular (CV) events occurred in 4 patients who received celecoxib and in 5 patients who received placebo, respectively. Compared with those who received placebo, patients who received celecoxib had no signif icant increase in occurrence of CV events (hazard ratio = 0.84, 95% CI = 0.23-3.15). Among the adverse events acquired by interview survey, only the frequency of bloating was signif icantly higher in patients treated with celecoxib than in those treated with placebo. CONCLUSION: Treatment of gastric cancer with celecoxib is not associated with increased risk of gastroduodenal ulcer and cardiovascular events.展开更多

METHODS:Data were collected from 93 patients submitted to upper digestive endoscopy due to dyspeptic symptoms. The patients were either negative(group A)or positive (group B)to H pylori by means of both histological detection and urease tests.Before endoscopy,peripheral blood was collected for the investigation of anti-H pylori IgG and IgA antibodies.To perform the urease test,biopsies were obtained from the gastric antrum.For the histological evaluation,biopsies were collected from the gastric antrum (greater and lesser curvatures)and the gastric body. Following this,duodenal fluid was collected from the first and second portions of the duodenum.For the serological assaying of anti-Hpylori IgG and IgA,and anti-Hpylori IgA in duodenal fluids,the ELISA method was utilized. RESULTS:The concentration of serum IgG showed sensitivity of 64.0%,specificity of 83.7%,positive predictive value of 82.0%,negative predictive value of 66.6% and accuracy of 73.1% for the diagnosis of H pylori infection.For the same purpose,serum IgA showed sensitivity of 72.0%, specificity of 65.9%,positive predictive value of 72.0%, negative predictive value of 67.4% and accuracy of 69.8%. If the serological tests were considered together,i.e.when both were positive or negative,the accuracy was 80.0%, sensitivity was 86.6%,specificity was 74.2%,positive predictive value was 74.2% and negative predictive value was 86.6%.When values obtained in the test for detecting IgA in the duodenal fluid were analyzed,no significant difference(P=0.43)was observed between the values obtained from patients with or without H pylori infection. CONCLUSION:The results of serum IgG and IgA tests for H pylori detection when used simultaneously,are more efficient in accuracy,sensitivity and negative predictive value, than those when used alone.The concentration of IgA antibodies in duodenal fluid is not useful in identifying patients with or without H pylori.展开更多

The wall of the first, second, and third portions of the duodenum was extensively lacerated, and the pancreas was longitudinally transected along the supe- rior mesenteric vein-portal vein trunk. The pancreatic head and the uncinate process were devitalized and the distal common bile duct and the proximal main pancreatic duct were completely detached from the Vater ampulla. The length of the stump of distal common bile located at the cut surface of remnant pancreas was approximately 0.6 cm. A simplified Kausch-Whipple＇s procedure was performed after debride- ment of the devitalized pancreatic head and resection of the damaged duodenum in which the stump of distal common bile duct and the pancreatic remnant were embedded into the jejunal loop. Postoperative wound abscess appeared that eventually recovered by conservative treatment. Dur- ing 16 months follow-up the patient has been stable and healthy. A simplified pancreaticoduodenectomy is a safe alternative for the Whipple procedure in managing complex pancreaticoduodenal injury in a hemodynamically stable patient.展开更多
