ABSTRACT
AIM To study the effects of No.1 Weiyan Decoction (Codonopsis Radix,Paeoniae Radix alba,Taraxaci Herba,etc.) on hypoxia and hypoxic tolerance in gastric mucosal epithelial cells in rats with precancerous lesion of gastric cancer (PLGC).METHODS Forty rats were randomly divided into normal,model,Vitacoenzyme Tablets and No.1 Weiyan Decoction groups.Except for the normal group,the rats in the other groups were given with N-methyl-N'-nitro-N-nitrosoguanidine and Little Chengqi Decoction to establish a PLGC rat model.Ten weeks after the administration,the gastric mucosal epithelial microvascular ultrastructure was observed,the expressions of Hif1a mRNA,HIF-1 α protein and VEGF protein in gastric mucosal epithelium were detected.RESULTS Compared with the normal group,the number of microvasculatures in gastric mucosal epithelium was decreased;lumen was severely stenosed or expansive;inner wall was not smooth and had adhesion;vascular endothelial cells were swollen;the expression of Hif1α mRNA showed an increasing trend;the expressions of HIF-1α protein and VEGF protein were anomalous in the model group.Compared with the model group,the gastric mucosal vascular lesion of PLGC rats was improved,and the expressions of Hif1a mRNA,HIF-1α protein and VEGF protein were significantly decreased in the No.1 Weiyan Decoction group.CONCLUSION No.1 Weiyan Decoction can improve hypoxia and hypoxia tolerance,and induce angiogenesis in gastric mucosal epithelium in PLGC rats.
ABSTRACT
Objective To investigate the protective effects ofDasangju Mixture on the liver injury induced by delayed-type hypersensitivity in mice; To discuss its mechanism of anti-inflammatory-immunity.Methods After enterocoelia intravenous injection of cyclophosphamide was used, 2,4,6-picryl chloride was used twice for exterior coating for skin of abdomen to cause sensation of skin. Then percutaneous transhepatic puncture was used to attack for modeling. Male Kunming mice were randomly divided into blank group, model group, high-, medium- and low-dose treatment groups. The high-, medium- and low-dose treatment groups were given Dasangju Mixture for gavage, once a day for 7 days. ELISA was applied to determine the serum levels of aspartate aminotransferase (AST), alamine aminotransferase (ALT) and tumor necrosis factor (TNF)-α. Pathological features of liver tissue were observed by HE staining.Results Compared with the blank group, the levels of AST, ALT and TNF-α in the model group increased significantly (P<0.05); Compared with the model group, the levels of AST, ALT and TNF-α in the high-, medium- and low-dose treatment groups decreased significantly (P<0.05,P<0.01,P<0.001); Compared with the model group, high-, medium- and low-dose treatment groups can better alleviate topical inflammation infiltration and edema of liver tissue.ConclusionDasangju Mixture has certain protective effects on the liver injury induced by delayed-type hypersensitivity in mice.
ABSTRACT
Objective To study the relationship between operative procedures and complication of colorectal carcinoma with acute colonic obstruction in the elderly patients. Methods 65 elderly patients undergoing emergency operation for acute colonic obstruction were analyzed retrospectively. One stage tumor resection and anastomosis was performed in 25 cases with right-side colonic lesion and in 26 cases with left-side colonic lesion, Hartmann operation in 8 cases, Dixon operation in 4 cases and proximal colostomy in 2 cases. Results In 65 cases, 13 cases of postopera-tive complications,the rate was 20.0% (13/65) ,which infected with toxic shock two cases,four cases of pulmonary infection,anastomotic leakage two cases, wound infection, split 2 cases, death three cases, the mortality rate was 4.6%. The rates of postoperative complications in right-side colonic lesion, left-side colonic lesion, Hartmann opera-tion and Dixon operation were 69.2% ,0,30.7% and 0 respectively(P < 0.05 ～ 0.01). Conclusion Acute obstruc-tion of colon cancer,the right-side colonic lesion were safe,feasible and few complications in colorectal carcinoma with acute colonic obstruction.
ABSTRACT
Objective To compare two types of digestive reconstruction and postoperative complications after total gastrectomy in patients with gastric carcinoma. Methods Roux-en-Y esophagojejunostomy and P-type Roux-en-Y esophagojejunostomy were performed in 50 patients with gastric carcinoma after total gastrectomy. The operating time and postoperative complications were observed. Results The gastrointestinal symptoms for Roux-en-Y esophagojeju-nostomy and P-type Roux-en-Y esophagojejunostomy serve as : diarrhea ( 11.8% and 12.1% ), dumping syndrome (3.9% and 3.3% ) and reflux esophagitis(5.9% and 6.0% ) ,the incidence of the difference was not significant ( than,P>0.05 ). The postoperative complications in P-type Roux-en-Y esophagojejunostomy( 13.1% ) slightly higher that Roux-en-Y esophagojejunostomy( 11.1% ) ,but the difference was not significant( P>0.05 ). Roux-en-Y esoph-agojejunostomy average operative time(3.1±0.3)h was significantly reduced than P-type Roux-en-Y esophagojeju-nostomy(3.7±0.2)h(t=3.35,P<0.05). Conclusion Roux-en-Y esephagojejunostomy and P-type Roux-en-Y esophagojejunostomy is a suitable type after total gastrectomy for patients with gastric carcinoma, but the former opera-tive time was shorter.
ABSTRACT
Objective To observe the effect of treating chronic severe hepatitis modified Yinchen Zhufu Decoction.Methods 46 chronic severe hepatitis patients (belonging to Ymhuang syndrome in TCM) were randomly recruited in to a treatment group (26 cases) and a control group (20 cases). Indexes as symptoms, signs, liver functions, prothrombin activity (PTA), prothrombin (ALB) and complications were used for evaluating therapeutic effects. Results After four weeks' treatment, of all 26 cases in the treatment group, 23 cases were effective (occupying 88.5%) and 3 cases were inefficacy (occupying 11.5%); while of all 20 cases in the control group, 11 cases were effective (occupying 55%) and 9 cases were inefficacy (occupying 45%). There was significant difference between the two group in therapeutic effects( P＜0.05 ). TBIL in both groups were decreased after the treatment(P＜ 0.05 ), and the decrease amplitude in the treatment group was much bigger than the control group (P＜0.05). PTA in the treatment group was increased after the treatment (P＜0.05), but this increase amplitude showed no significant difference comparing with the control group (P＞0.05). ALB showed significant difference between the two groups after treatment, with P＜0.05, but complications demonstrated no significant difference between the two groups after treatment, with P＞0.05. Conclusion Modified Yinchen Zhufu Decoction has good therapeutic effects in treating chronic severe hepatitis of yinhuang syndrome.
ABSTRACT
Objective To investigate the clinical and immunohistochemical features,diagnosis and treatment of gastrointestinal stromal tumor(GIST). Methods Clinic and pathological datas of 38 cases with GIST were retrospectively analyzed. Results The most common clinal maifestions were abdominal pain,distention or discomfort in 24 cases(50%), abdominal mass in 10,melena and liematemesis in 8 cases. The tumor was located in the stomach in 20 cases, the small infestine in 14,the colorectum in 4.All the cases underwent operation. Conclusion Endoscopy and imaging examination are main methods to detect GIST. Surgical resection is the main mothod of pathologic diagnosis and treatment.
ABSTRACT

ABSTRACT
Objective:To study the efficacy and safety of mirtazapine and paroxetine in patients with first-episode climacteric depression. Methods:A 8-week double-blind study was conducted with 90 female patients suffered with climacteric first-episode depression. Subjects were randomly assigned to either mirtazapine (n=45) or paroxetine (n=45). All subjects were evaluated with Hamilton Rating Scale for Depression-17 (HAMD-17), Hamilton Rating Scale for Anxiety,and Treatment Emergent Symptom scale (TESS) at baseline, the end of week 1, 4 and 8 after treatment. The study had lasted for 8 weeks.Results:The response rate between two groups (mirtazapine 88.9% vs paroxetine 82.2%) was similar. There were significant differences on the scores of HAMD between the two groups at the end of 1st and 8th week, and HAMA at the 1st week after treatment(21.3?3.5/25.2?2.9,18.2?3.2/21.5?2.4,t=-2.367、-3.514,P=0.042、0.032;7.2?3.5/9.8?2.3,t=-3.258,P=0.035). Mirtazapine had increased food appetite(15.6%), body weight(13.3%), hydropsia(8.9%), dry mouth(6.7%), sleep disorder and nausea(4.4%). Meanwhile paroxetine had dry mouth(22.2%), sleep disorder(20.0%), nausea(17.8%), tremor(15.6%), restlessness/agitation(13.3%) and sexual disturbance(11.1%).Conclusion:Mirtazapine has rapid response, strongly antidepressive effect in female climacteric first-episode patients and less side-effects.
