Objective To investigate whether angiotensin Ⅱ (AngⅡ) can regulate the expression of MIF in macrophages via the NF-κB pathway. Methods Western Blot, real time RT-PCR and ELISA were used in the present study. Results Western blot result showed that the expression of NF-κBp65 gradually increased with the increase of the concentration of AngⅡ. Results of real time RT-PCR and ELISA revealed that MIF mRNA expression and the content of MIF were significantly higher in AngⅡ group than those in the control group. PDTC could reverse the effect of AngⅡ on MIF mRNA expression and MIF secretion in macrophages. Conclusion AngⅡ can promote MIF mRNA expression and MIF secretion in macrophages via the NF-κB signaling pathway.

Objective To analyze the distribution of human papillomavirus (HPV) genotype in the diseases associated with HPV infection and explore the role of HPV genotype in these diseases. Methods Retrospective analysis was carried out to compare HPV genotypes of 353 outpatients suffering the diseases associated with HPV infection including cervical caner,cervical intraepithelial neoplasia (CIN),genital duc condyloma,and subclinical cervical human papillomavirus infection (SPI) in our department from January to October 2008. HybriMax were used to detect HPV genotype. The distribution data of HPV genotype were statistically analyzed. Results Totally 176 HPV positive females were found with a positive rate of 49.86%. HPV positive rate in cervical cancer was 100%,and all of them were high risk HPV. The positive rate was increased with the severity of CIN,and the higher histological-grade was,the higher HPV positive rate was (P

Objective To explore the effects of rhubarb navel therapy on fecal continence in rectal cancer patients with colostomy.Methods 60 patients with colostomy were randomly divided into the experimental group and the control group with 30 patients in each group.Patients in the control group received routine therapy and health education whereas the experimental group received 30-day extra rhubarb navel therapy started on the 15th day after the operation.The two groups were compared in postoperative 3 months with the following factors:the functions of colostomy and the formation of bowel regularity.Results The scores of the scale about the functions of permanent abdominal colostomy were improved in both groups.However,the score in the experimental group was much higher than that in the control group.The number of patients forming bowel regularity in the experimental group was more than that in the control group (19 and 4 cases respectively).Conclusions Rhubarb navel therapy is beneficial to rectal cancer patients with colostomy to improve the functions of colostomy and form the bowel regularity.

Objective To observe the efficacy of prophylactic use of gramsetron(Gra) combined with dexamethasone(DEX) on preventing postoperative nausea and vomiting(PONV) after umbilical one-trocar laparoscopic appendectomy(UOTLA)in children.Methods Sixty children requring UOTLA under general anesthesia were allocated randomly into 3 groups,and each of group included 20 children.Group saline(C),group Gra 40 ?g/kg,group Gra 40 mg/kg and group DEX 0.2 mg/kg(Gra+DEX) were respectively injected intravenously after appendectomy performed outside the abdominal cavity during the operation.Results The incidence of PONV decreased significantly in group Gra and group Gra+DEX than that in group C(Pa

Objective To investigate the pathological diagnosis of high-grade intraepithelial neoplasia in gastric biopsy.MethodsOne hundred and forty-three cases diagnosed by gastric biopsy as high-grade intraepithelial neoplasia were analyzed by light microscopy,and were compared with the pathological findings of surgical specimens in 60 cases and a second biopsy in 13 cases.Results Among the sixty cases treated surgically following the gastric biopsies,no carcinoma was found in 6,while the other 54 were diagnosed as gastric adenocarcinoma,27 in advanced stage and 27 in early stage,respectively.Fifteen cases were well-differentiated,24 moderately-differentiated,12 poorly-differentiated and 3 were of mucinous type.Four of the 13 cases with a second biopsy were diagnosed as well-differentiated adenocarcinoma,8 low-grade intraepithelial neoplasia and 1 chronic inflammation.The colorectal adenomas-like changes were morphologically found in 6 surgically-treated cases without carcinoma,5 of whom mucous muscles were not found by biopsy.Fibroblastic reactions were found in 9 cases,all of which were diagnosed as adenocarcinoma in surgical specimens.Conclusion Ninety percent of the cases who are diagnosed as high-grade intraepithelial neoplasia by biopsy may have already been complicated with adenocarcinoma.The location and depth of the specimen in gastric biopsy have a considerable influence on pathological diagnosis.The fibroblastic reaction may be considered as an important marker for gastric adenocarcinoma in pathological diagnosis of gastric biopsy.

Objective To explore the feasibility of using contralateral breast as the donor for immediately breast reconstruction or chest wall defect repair after mastectomy in breast cancer patients. Methods From Jul. 2013 to Mar. 2016, contralateral breast fat flap was used as the donor for 8 breast cancer patients with immediate autologous non-microsurgical breast reconstruction or chest wall defect repair after mastectomy. All participants in this study received preoperative oncological screening with ultrasound, mammography, and magnetic resonance imaging which revealed the absence of pathological abnormalities in the donor breast. Results Among the 8 pa-tients, 4 patients underwent immediate breast reconstruction and 4 received chest wall defect repair. Only 1 pa-tient undergoing breast reconstruction had minor complications with little or no effect on the final outcome. No patient undergoing chest wall defect repair had postoperative complications. The functional and aesthetic out-comes were very satisfactory. Regular follow-ups were from 3 to 34 months with no recurrence found up to the present. Conclusions This article presents the first case for immediately breast reconstruction or chest wall de-fect repair using contralateral breast as the donor. The surgical method has some complications but with good aesthetic outcomes, which can be an option for breast cancer patients with hypertrophic and ptotic breast.

Objective To investigate the changes of serum thyroxine level in obstructive sleep apnea-hy-popnea syndrome(OSAHS) patients and to assess the role of serum thyroxine in the development of OSAHS. Meth-ods Polysomnography was used to examine the patients with OSAHS and fasting plasma serum thyroxine level were higher in obese OSAHS patients than in obese controls[ (43.56±3.48)cm vs (38.33±3.08)cm,t =4. 258,P < 0.05 ], in non-obese OSAHS patients than in non-obese control group [ (40.50±1.05 )cm vs (36.17±3.13 )cm, t = 3. 146 ,P < 0.05 ] . The levels of FT3 was (6.35±3.15 ) pmol/L in obese OSAHS patients and ( 4.08±2.37 ) pmol/L in control subjects ( t = 2.203 ,P < 0.05 ). That was ( 3.42±0.57 ) pmol/L in non-obese OSAHS patients related with AHI and microarousal index (r = 0. 500, P < 0.05;r = 0.561, P < 0.05 ), and FT4 was also positively with neck circumference( t = 0.489, P < 0.05 ), TSH level was negatively correlated with neck circumference ( t = - 0.500, P < 0.05 ) and was positively correlated with the percentage of body fat ( r = 0.498, P < 0.05 ). Conclu-sions The FT3 levels are significantly higher in the OSAHS patients than that in control subjects, though all FT3 lev-els are normal, suggesting that there are possibility to have abnormal metabolism. At the same time, FT3 level is posi-tively correlated with neck circumference ,suggesting that the OSAHS patients' higher neck circumference is correla-ted with thyroxine.

Objective To investigate the event-based prospective memory(EBPM)and time-based prospective memory(TBPM)in schizophrenia patients with concomitant metabolism syndrome,and to provide theory basis for early intervention and treatment.Methods According to inclusion standard,50 schizophrenia patients with concomitant metabolism syndrome and 50 schizophrenia patients without metabolism syndrome matched in age,gender and education were assessed with a neuropsychological battery of tests including EB-PM and TBPM tasks.Results In the EBPM task,there was significant difference between schizophrenia pa-tients with and without metabolism syndrome (3.46±0.91 vs 3.86±0.81, t=-2.326, P=0.022).A statistically significant difference in TBPM was observed between schizophrenia patients with and without metabolism syn-drome (3.02±1.12 vs 3.78±0.89, t=-3.770, P=0.000).Conclusion The schizophrenia patients with me-tabolism syndrome have severer prospective memory impairment than those without metabolism syndrome.

Due to the irregular of diet and overfeeding greasy and surfeit flavor closely associated with hyperuricemia disease, the lipid emulsion containing high cholesterol was used to model. To obtain a more stable and sustained animal model for the efficacy evaluation of traditional Chinese herbs, we observed the influence on the serum uric acid of rat induced by the lipid emulsion compared with high purine diet. 36 SD male rats were randomized to the normal control group, high purine diet group and lipid emulsion group respectively. The general behavior, body weight and daily food intake of rats were observed. The orbital blood was taken to separate into the serum and 24 hours urine was collected. The serum indexes such as UA, BUN, Cr, ALT, AST, TC, TG, LDL-c were determined every 2 weeks, and XOD, ADA enzyme activity were determined at the 4th week. The urine indexes such as UA, Cr and Cua/Ccr were determined at the 4th week. After stopping modeling, the serum UA were determined two weeks and four weeks later respectively. At the 2nd week, the body weight and daily food intake of rats in the lipid emulsion group reduced significantly, and the level of serum UA, BUN, Cr, TC, LDL-c, ATL, AST raised significantly meanwhile TG reduced. At the 4th week, the serum UA in high purine diet group did not raise, and the serum XOD raised obviously while ADA did not; the serum UA in lipid emulsion group was higher significantly, and the serum XOD and ADA raised while Cua/Ccr reduced obviously. At the 6th weeks, the serum UA in both the high purine diet group and lipid emulsion group raised obviously. After stopping modeling, the serum UA in lipid emulsion group still maintained a high level at the 2nd week and back to the normal level at the 4th week. Compared with high purine diet, the hyperuricemia model induced by lipid emulsion forms earlierand more stable. It maybe has great value to study the pharmacodynamics of traditional Chinese medicine treatment to hyperuricemia disease. Its mechanism may be related to increasing XOD and ADA enzyme activity which can promote uric acid synthesis, meanwhile inhibiting of uric acid excretion.
