Objective To explore the influence of Shenqifuzheng injection on efficacy of chemotherapy and immune function in patients with gastric cancer after surgery.Methods 60 postoperative patients with gastric cancer were selected as the research subjects,and were randomly divided into the control group and observation group by the digital table,30 cases in each group.The control group was given FOLFOX regimen chemotherapy.The observation group received FOLFOX regimen combined with the treatment of Shenqifuzheng injection.The recurrence and metasta-sis,survival,immune function and adverse reactions of the patients were observed and the patients were observed before and after chemotherapy.Results The chemotherapy cycle of the observation group was (3.95 ±0.40),which was significantly higher than (3.40 ±0.30)of the control group,the difference was statistically significant (t =6.025,P <0.01).The progression free survival in the observation group was (9 ±2.4)months,which was significant-ly longer than (6.6 ±3.2)months in the control group,the difference was statistically significant (t =3.286,P <0.01).The reduction rate in the observation group was 6.67%,which was lower than 26.67% in the control group, the difference was statistically significant (χ2 =4.320,P <0.05).The incidence rate of nausea and vomiting in the observation group was 6.67%,which was lower than 26.67% in the control group,the difference was statistically sig-nificant (χ2 =4.320,P <0.05).KPS[(83.51 ±15.37)points]and QLQ -C30[(82.01 ±9.45)points]of the observation group were significantly higher than those in the control group [KPS (74.62 ±13.22)points and QLQ -C30 (74.62 ±13.22)points],the differences were statistically significant (t =2.298,2.491,all P <0.05).After chemotherapy,gastric cancer patients ratio of CD +3 ,CD +4 ,CD +4 /CD +8 in the observation group were higher than those of the control group and the ratio of CD +4 /CD +25 in the observation group was lower than control group,the differences were statistically significant (all P <0.05).Conclusion Shenqifuzheng injection combined with FOLFOX chemo-therapy for gastric cancer patients has low adverse reaction rate,and can effectively improve the immune function.

Objective To study the effect of evidence-based nursing on improving the nursing requirement of patients with ureter external drainage and inner stent drainage after urological operation. Methods 62 patients in department of urinary surgery from June 2009 to October 2011 were selected as research object,and they were randomly divided into the control group and the observation group with 31 cases in each group,the two groups adopted routine nursing mode and evidence-based nursing mode respectively.Then the nursing requirement and nursing effect before and three and five days after nursing were compared between two groups. Results All the patients existed needs of related knowledge guidance,unhealthy emotion adjustment and social support,and the needs of patients between ureter external drainage and inner stent drainage showed no significant differences,improvement level of each items of the observation group after nursing were all better than those of the control group. Conclusions The patients with ureter external drainage or inner stent drainage have needs of related knowledge guidance,unhealthy emotion adjustment and social support,and the evidence-based nursing mode can effectively improve the patients'demand situations of these items.

Objectives To explore the feasibility ofdiagnosis of Perimembranous Ventricular Septal Defect with Right Aortic Valve Prolapse by ultrasonic echocardiography. Methods 131 VSD patients aged 1 to 22 years, weight 8.0 to 54.0 kg, underwent transthoracic echocardiography (TTE) and left ventricular angiography to show the diameter of VSD and the degree of AVP. Results Among 131 patients, 87 cases were diagnosed as VSD,14 as VSD with slight AVP, 12 as, VSD with middle AVP, and 18 as VSD with severe AVP by ultrasonic echocardiography respectively. After the left ventricular angiography and aortic root angiography , it proved that positive rate of VSD was 44.8%, positive rate of VSD with slight AVP was 42.86%, positive rate of VSD with middle AVP was 58.3%,and positive rate of VSD with severe AVP was 83.3%. Conclusion The transthoracic echocardiography (TTE) contributes to diagnosis of severe degree of AVP,while TTE evaluates the slight degree of AVP incorrectly enough. Left ventricular angiography and aortic root angiography are needed to realize the di-agnosis of AVP.

Objective To observe and analyze the medium and long term follow-up data of arrhythmias after transcatheter closure of children with ventricular septal defect (VSD). Methods Retrospectively analyzed the clinical data of 1071 children with VSD, who successfully underwent transcatheter device closure, at l, 3, 6, 12 months and ev-ery year post procedure from March 2002 to December 2010. Results Of all 1071 children, 272 cases (25.4%) were ob-served of having arrhythmias within 1 month after intervention, mainly including atrioventricular block (AVB), branch block, junctional tachycardia, atrial and ventricular tachycardia, frequent contractions, etc. Among them, 22 cases (2.1%) had above II degree AVB, complete left bundle branch block (CLBBB) and other causes of serious arrhythmias. After treatment, all cases got better and no permanent pacemaker was necessary. After 1 to 107 months (2.8±1.7 years) fol-low-up, 161 cases (18.2%) were observed of having persistent abnormal ECG mainly caused by AVB and branch block, including 10 cases (1.1%) with serious arrhythmias. In 4 cases with late-onset AVB, 3 cases had already appeared AVB in early postoperative, 1 case had recurrence CLBBB, left ventricle enlarge, and died of heart failure during follow up. Four cases were implanted permanent pacemaker. Conclusion During follow-up, serious arrhythmias after VSD closure, such as AVB or CLBBB, have high risk of recurring. Conduction block arrhythmias may reappear or worsen, while arrhythmias like tachycardia and premature heart rhythm mostly return to normal.

Background:Protein inhibitor of activated STAT 1( PIAS1 )is an important regulator for inflammatory signaling network,which is low expressed in gastric cancer and associated with development of cancer,but its mechanism has not been elucidated. Aims:To investigate the effect of PIAS1 on epithelial-mesenchymal transition( EMT)of gastric cancer under inflammatory microenvironment. Methods:Recombinant adenovirus Ad5/F35-PIAS1 and Ad5/F35-null were constructed and transfected into gastric cancer cell line SGC-7901,mRNA and protein expressions of PIAS1 were detected by RT-PCR and Western blotting,respectively. SGC-7901 cells were divided into IL-6 treatment group,Ad5/F35-PIAS1﹢IL-6 treatment group and Ad5/F35-null﹢IL-6 treatment group. Cell proliferation was measured by MTT method,migration and invasion capacities were assessed by wound healing test and Transwell chamber invasion assay. Protein expressions of E-cadherin,Snail,Twist,Vimentin and P-p38MAPK were assessed by Western blotting. Results:The transfection of Ad5/F35-PIAS1 significantly increased the expressions of PIAS1 mRNA and protein in SGC-7901 cells. Compared with IL-6 treatment group and Ad5/F35-null﹢IL-6 treatment group,capacities of cell proliferation,migration and invasion were significantly decreased(P ﹤0. 01);protein expressions of Snail,Twist,Vimentin and P-p38MAPK were significantly decreased while expression of E-cadherin protein was significantly increased in Ad5/F35-PIAS1 ﹢IL-6 treatment group ( P﹤0. 01). No significant differences in above-mentioned indices were found between IL-6 treatment group and Ad5/F35-null﹢IL-6 treatment group(P﹥0. 05). Conclusions:PIAS1 could inhibit EMT of gastric cancer cells under inflammatory microenvironment,and may play an important role in inhibition of tumor invasion and metastasis.

BACKGROUND:There is no effective drug for idiopathic pulmonary fibrosis (IPF), because of a lack of the animal model imitating the complete pathogenesis of human IPF. Therefore, it is critical to establish an ideal animal IPF model used for investigating the underlying pathogenesis and developing a kind of effective drug. OBJECTIVE:To establish an animal model that can mimic more characters of human IPF. METHODS:Seventy male C57BL/6 mice were randomly divided into two groups, fol owed by subjected to the intraperitoneal injection of bleomycin (35 mg/kg) on days 1, 4, 8, 11, 15, 18, 22, and 25, twice (group A) or once (group B) a week. Mice were sacrificed at 2, 4, 6, 8, and 10 weeks after the eighth injection, and the lung tissues were moved used for hematoxylin-eosin, Masson and immunohistochemical stainings. RESULTS AND CONCLUSION:There were various degrees of alveolitis and pulmonary fibrosis in the two groups at different time points after the last injection. The scores of alveolitis and pulmonary fibrosis in the group A began to gradual y increase from the 2nd week and reached the highest level at the 6th-8th weeks until the 10th week. In contrast, the scores of alveolitis and pulmonary fibrosis in the group B peaked at the 2nd week, then fluctuately decreased, and were significantly lower than those in the group A at the 6th week (P<0.05). Immunohistochemistry showed that type I col agen deposition was mainly distributed in the subpleural region, peri-vascular region and alveolar septa, which was consistent with Masson staining findings. The expression levels of transforming growth factorβ1 (TGF-β1) andα-smooth muscle actin (α-SMA) in the regions developing alveolitis and pulmonary fibrosis were significantly increased. In the group A, the expression levels of type I col agen, TGF-β1,α-SMA, and the hydroxyproline content in the lung tissues reached the peak level at 6-8 weeks. However, in the group B, al above indicators reached the highest level at the 2nd week, but gradual y decreased thereafter. At the 4th week, the expression Levels of TGF-β1 andα-SMA in the group B were significantly lower than those in the group A (P<0.05). At the 6th week, the hydroxyproline and type I col agen levels in the group B were significantly lower than those in the group A (P<0.05). In conclusion, the mouse model of pulmonary fibrosis induced by intraperitoneal injection of 35 mg/kg bleomycin twice weekly can be used to mimic the repetitive wound healing process, pathological morphology and cytokine changes of human IPF, which is prone to administration, with better stability and repeatability. This model is of great significance for the study on IPF. Subject headings:Disease Models, Animal;Pulmonary Fibrosis;Bleomycin

Objective To study the different oral compound polyethylene glycol electrolyte powder on the effect of bowel preparation before colonoscopy.Methods A total of 602 inpatients or outpatients were selected from department of gastroenterology,and they were randomly divided into tranditional group(n =288)and improvement group(n =314).All patients took a dose of two box of compound polyethylene glycol electrolyte powder 4 hours before colonoscopy.Endoscopic doctor investigated the antibiotic tolerance,adverse reactions,heart rate,blood pressure,blood electrolytes and blood glucose during treatment in form of questionnaire with single blind Bosdon bowel preparation scale (BBPS)score.Results The BBPS scores of the tranditional group and improvement group were (7.03 ± 1.24)points,(7.82 ±1.12)points,the score of the improvement group was significantly higher than the traditional group(t =2.259,P <0.05).The taste scores were (1.89 ±0.07)points,(1.25 ±0.09)points (t =2.624,P <0.05),the fully taking rates were 90.28%,95.86%(χ2 =7.375,P <0.05 ),and the second taking rates were 88.54%,93.95%(χ2 =5.566,P <0.05).In contract,the score of adverse reactions of the improvement group was significantly lower than that of the traditional group [(2.58 ±0.07)points vs(2.22 ±0.09)points,t =2.068,P <0.05].There was no significant difference of colonoscopy time between the two groups[(10.78 ±4.34)min vs (9.89 ± 1.77)min,t =1.766,P >0.05 ],althought the improvement group was shorter than the tranditional group. Conclusion The modified way of oral compound polyethylene glycol electrolyte powder not only can improve the qulity of intestinal cleaning,but also acts as a more effective method in preparation of colonoscopy due to its high tolerance, good comfort,less pain and high acceptance of patients.Therefore,it is worthy of clinical promotion and application.

Background:Colorectal polyps,especially adenomatous polyps are the precusor of colorectal cancer. Screening and polypectomy by using colonoscopy is an important approach for prevention of colorectal cancer. Aims:To conduct a retrospective analysis among 1 613 cases of patients with colorectal polyps in Jiading District,Shanghai,China for guiding the management of colonoscopy surveillance of colorectal polyps. Methods:A total of 2 652 colorectal polyps detected by colonoscopy from Jan. 2013 to Aug. 2014 in the Endoscopy Center of Shanghai Ruijin Hospital Northern Branch were recruited in the study. Clinicopathological features of the polyps,coincidence rate of biopsy pathology and polypectomy pathology,and the re-detected polyps in colonoscopic follow-up were analyzed. Results:In 2 652 colorectal polyps,1 996 (75. 3% )were located in distal colon;adenomatous polyps accounted for 77. 5%(2 056 / 2 652)of the polyps detected by colonoscopy,of which 804(39. 1% )were found to have intraepithelial neoplasia. Both biopsy pathology and polypectomy pathology were obtained in 447 polyps,with an overall coincidence rate of 60. 4% ;as for adenomas,the coincidence rate was 68. 1% . Two hundred and eighteen pathologically proved polyps were found in a 1. 5-year colonoscopic follow-up, among which 74. 3% were adenomatous polyps;the re-detection rate of polyps located in proximal colon or less than 1. 0 cm in diameter was significantly higher than polyps located in distal colon and more than 1. 0 cm in diameter, respectively(12. 3% vs. 6. 9% and 9. 0% vs. 4. 5% ,P all < 0. 01). Conclusions:Adenomatous polyps account for high proportion of colorectal polyps detected by colonoscopy. Pathological examination of resection specimens and periodical follow-up are important for patients with colorectal polyps after endoscopic polypectomy.
