The survey collected patient general information and anesthesia data, including overall medical experience and pain management. Thirty minutes after colonoscopy surgery, samples of venous blood were collected and the biochemical indicators of gastrointestinal function were analyzed. RESULTS: There were 98 female and 62 male respondents. Indolent colonoscopy was found to be more suitable for mid to older-aged patients. The necessary conditions for the diagnosis of digestive diseases were required in 65 of the 73 inpatients. Adverse reactions to the intraoperative process included two cases of body movement and two cases of respiratory depression. Gastrin and vasoactive intestinal peptide levels were slightly increased. However, somatostatin and endothelin levels were slightly decreased. CONCLUSION: This study revealed that dezocine combined with propofol can be successfully used for the anesthetization of indolent colonoscopy patients without pain and should be widely used.展开更多

This genderdifference may be related to the effects of sex hormones onthe liver. The aim of the present work was to investigatethe effects of estrogen on CCL4-induced fibrosis of the liverin rats.METHODS: Liver fibrosis was induced in male, female andovariectomized rats by CCL4 administration. All the groupswere treated with estradiol(1 mg/kg) twice weekly. Andtamoxifen wasgiven to male fibrosis model. At the end of 8weeks, all therats were killed to study serum indicators andthe livers.RESULTS: Estradiol treatment reduced aspartateaminotransferase(AST), alanine aminotransferase (ALT),hyaluronic acid(HA) and type IV collagen(CIV) in sera,suppressed hepatic collagen content, decreased the areas ofhepatic stellate cells (HSC) positive for α-smooth muscle actin(α-SMA), and lowered the synthesis of hepatic type I collagensignificantly in both sexes and ovariectomy fibrotic rats inducedby CCL4 administration. Whereas, tamoxifen had the oppositeeffect. The fibrotic response of the female liver to CCL4treatment was significantly weaker than that of male liver.CONCLUSION: Estradiol reduces CCL4-induced hepaticfibrosis in rats. The antifibrogenic role of estrogen in theliver may be one reason for the sex associated differencesin the progression from hepatic fibrosis to cirrhosis.展开更多

METHODS: The CT scans of 12 patients with abdominal nonhematogenous disseminated TL suggestive of neoplasm were retrospectively analyzed in this review. The final diagnoses were confirmed by lymph node pathology for seven patients and by laparoscopic surgery for five patients. All of the patients were treated at our institution between April 1995 and August 2009. RESULTS: The sites of involvement were the periportal (n = 6), peripancreatic (n = 3), periaortic (n = 3), and mesenteric (n = 2) regions. On the plain CT scan, the lymphadenopathy showed a heterogeneous isodensity or hypodensity in 11 patients and a low density in one patient. Peripheral enhancement was observed on the dynamic contrast-enhanced CT scans for all patients. In two cases, scans were more revealing during the portal venous and delayed phases. CONCLUSION: Abdominal lymphadenopathy with predominant peripheral rim-like enhancement on the dynamic contrast-enhanced CT scan may suggest a diagnosis of TL.展开更多

Selective PCI supported by ECMO is a viable alternative for patients who are at very high risk for coronary artery bypass gratting (CABG). A previous study found that ECMO-assistcd PCI for patients with acute myocardial infarction complicated by profound cardiogenic shock might have improved 30-day and l-year survival rates, and we believe that ECMO is a viable mode of hemodynamic support in high-risk cases.展开更多
