Nineteen patients with low rectal cancer underwent laparoscopy-assisted anterior resection with prolapsing technique for sphincter preservation.The clinical data were retrospectively reviewed.Fecal continence was preserved successfully in all patients.There was no perioperative mortality,only two cases with anastomotic leak and one case with local recurrences.Laparoscopy-assisted anterior resection with a prolapsing technique for low rectal cancer is safe procedure and can be an alternative sphincter-preserving operation.

Objective: To study the apoptosis and the expression of proliferating cell nuclear antigen (PCNA) in colorec-tal neoplasms and their relationship with neoplasm biological behavior. Methods: Apoptotic index (AI) and proliferative index (PI) were determined in paraffin-embedded tissues from 62 cases of colorectal carcinomas, 15 cases of colon adenomas and 10 cases of normal colon mucosa with immunohistochemistry S-P method and TUNEL technique. Results: The difference of PI and AI was significant in normal colon mucosa, colon adenomas and colorectal carcinomas (P

To apply preventive T-shaped enterostomy in protective defunctioning stoma.Technique of enterostomy closure was only made in abdominal wall rather than abdominal cavity.A total of 78 patients undergoing protective ostomy from January 2005 to April 2012 were divided into two groups of routine enterostomy (group A,n =52) and protective T-shaped enterostomy (group B,n =26).The length of operation and average hospital stay in group A with stoma closure were(98 ± 16) min and (15.3 ± 5.2)days while those of group B (52 ± 9) min and (9.5 ± 2.3) days.The inter-group differences were statistically significant respectively (P ＜ 0.05).Therefore protective T-shaped enterostomy,showing advantages in operative skills,operative trauma and postoperative recovery time,is an effective technique and its application should be further promoted.

ObjectiveTo investigate the amount of bacteria and the expression of amylase and lipases in the drainage fluid in patients with intestinal fistulas with time courses.MethodsThe samples were collected from 16 patients with high intestinal fistulas from July 1998 to January 2008.The amounts of bacteria from the drainage fluid were measured 0,2 and 4 hours after taking out from the patients.At the respective time points,the intestinal juices were also collected to measure the amylase and lipase expressions.After reinfusion of succus entericus,thelevels of albumin,prealbumin,transferring,and fibronectin were measured at 0,7,and 14 days,ResultsThere was no significant increase of bacteria in the drainage fluid within 4 hours ( F(0,2) =18 812.50,P ＞ 0.05 ; F(0,4) =387 625.00,P ＞ 0.05).and there was no change in the expressions of amylase ( F(0,2) =190.60,P ＞ 0.05 ;F(0,4) =631.75,P＞0.05) and lipase within 4 hours (F(0,2) =204.10,P＞0.05; F(0,4) =1080.05,P＞0.05).After succus entericus reinfusion,the fibronectin (F(0,14) =74.24,P ＜ 0.01 ; F(7,14) =59.78,P ＜0.01),transferring (F(0,14) =0.46,P ＜ 0.01 ; F(7,14) =0.39,P ＜ 0.05 ),and prealbumin ( F(0,14) =54.37,P ＜ 0.05) were increased significantly.ConclusionsBacteria and enzymes do not increase in the drainage fluid within 4 hours in patients with intestinal fistulas.Therefore,it is safe and effective to reinfuse succus entericus.

Objective To analyze the relationship among the general self-efficacy,self-esteem and professional identification of nursing baccalaureate students and to provide some suggestions for educational practice. Methods A total of 403 nursing baccalaureate students in traditional Chinese medicine colleges were recruited. They were investigated with general self-efficacy scale (GSES), Rosenberg self-esteem scale(SES)and questionnaire for baccalaureate nursing students (QBNS). The relationship among general self-efficacy,self-esteem and professional identification was analyzed by multiple stepwise regression analysis. Results The mean score of general self-efficacy was 23.81± 5.27. There were significant differences in the score of general self-efficacy among different grades and enrollment methods (P<0.01). The nursing students,general self-efficacy was positively correlated with self-esteem,professional identification,professional emotion and professional skills(r=0.11-0.50, P<0.05). Conclusions Nursing educator should pay attention to the cultivation of self-esteem and professional identity in the training of nursing student in order to improve the self-efficacy of nursing students.

AIM: To observe the effects of sera containing Kang xian ling (a traditional Chinese medicine) on c-Met and its downstream MAPK signal molecules in HK-2 cells treated with transforming growth factor-β_1(TGF-β_1), so as to further explore the effective mechanism of anti-renal fibrosis of the traditional Chinese medicine. METHODS: Rat sera containing herbs were collected after rats were intragastrically administered with the herbs. HK-2 cells activated by TGF-β_1 were incubated with different heat-inactivated sera. The proliferation and expression of MAPK and the phosphorylation of MAPK in HK-2 cells were detected by Alarm blue and immunoblotting. RESULTS: No significant difference of cell proliferation between any two groups was observed. C-Met and the phosphorylation of its downstream molecules were also observed after incubated with different sera. CONCLUSION: The receptor c-Met of hepatocyte growth factor, and the phosphorylation of its downstream MAPK molecules can be regulated by the sera containing Kang xian ling.

Objective:To comprehensively investigate the prognostic significance of nodal skip metastasis and lobe-specific me-tastasis for patients with IIIa-N2 non-small-cell lung cancer (NSCLC). Methods:A total of 218 completely resected pN2-NSCLC cases with systematic lymph node dissections from 2008 to 2009 at Tianjin Medical University Cancer Hospital were enrolled. Mediastinal lymph node metastasis was subdivided into continuous metastasis and skip metastasis according to whether N1 lymph nodes were in-volved. Mediastinal lymph node metastasis was also classified into extensive metastasis and lobe-specific metastasis on the basis of whether the lymph nodes involved were within or beyond lobe-specific regions. Overall survival (OS) and disease-free survival (DFS) were compared. Results:For the whole cohort, 5-year OS was 21.6%and 5-year DFS was 16.8%. The 5-year OS for patients with skip metastasis or continuous metastasis were 37.6%and 22.0%, respectively (P=0.008). The 5-year DFS of patients with skip metastasis or continuous metastasis were 29.1%and 15.0%, respectively (P=0.022). The 5-year OS of patients with lobe-specific metastasis and ex-tensive metastasis were 38.3%and 20.4%, respectively (P=0.005). The 5-year DFS of patients with lobe-specific metastasis and exten-sive metastasis were 28.4%and 15.1%, respectively (P=0.009). According to the two patterns, patients were subdivided into three sub-groups:Group A (presence of both skip metastasis and lobe-specific metastasis), Group B (presence of skip metastasis only or lobe-spe-cific metastasis only), and Group C (presence of non-skip metastasis and non-lobe-specific metastasis). The 5-year OS of the three sub-groups were 47.1%(Group A), 28.1%(Group B), and 16.6%(Group C) (P=0.001), and the 5-year DFS of these subgroups were 35.2%(Group A), 20.8%(Group B), and 11.2%(Group C), respectively (P=0.002). Multivariate analysis demonstrated that the combined pat-tern was an independent prognostic factor for both OS and DFS. Conclusion:This combined pattern of lymph node metastasis was a strong prognostic factor for IIIa-N2 NSCLC. This pattern should be considered when predicting prognoses and during the selection of patients that will receive postoperative treatments.

Objective To explore the expression and clinical significance of chemokine receptor 6 (CCR6)/chemokine ligand 20(CCL20) axis in hepatocellular carcinoma (HCC).Methods From March 2003 to December 2005,48 patients with HCC were selected,and one specimen of HCC tissue and one of corresponding adjacent tissue were taken from every patient.Another eight patients with benign liver lesions were selected,and one specimen of surgical sectioned normal liver tissue of each was taken.The relative expression quantity of CCR6 and CCL20 at mRNA level was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR).And the expression of CCR6 and CCL20 at protein level was determined by immunohistochemisty methods.One-way analysis of variance (ANOVA) was performed for comparison among groups of measurement data.Chi-square test was used for rate comparison.The correlation coefficient was calculated by Spearman's method.Survival curves were plotted by Kaplan-Meier method and the survival rate was compared by Log-rank test.Results The relative expression quantity of CCR6/CCL20 at mRNA level in HCC tissues (0.99±0.21 and 0.46± 0.11) were significantly higher than those of para carcinoma tissues (0.33 ± 0.09 and 0.31 ± 0.07) and normal liver tissues (0.22±0.06 and 0.28±0.05),and the differences were statistically significant (F=127.43 and 21.10,both P＜0.05).The positive percentage of CCR6 protein expression in HCC tissues (54.17％,26/48) was significantly higher than that in para carcinoma tissues (16.67％,8/48) and normal liver tissues (0/8),and the difference was statistically significant (x2 =19.55,P＜0.05).There was no statistically significant difference in the positive percentage of CCL20 protein expression among HCC tissues (50.00％,24/48),paracarcinoma tissues (33.33％,16/48),normal liver tissues (2/8) (all P＜0.05).There was correlation between the positive percentage of CCR6 protein expression and that of CCL20 protein expression in HCC tissues (r=0.42,P＜0.05).The positive percentage of CCR6 protein expression was correlated with the pTNM stage of HCC,vascular tumor thrombosis,intrahepatic metastasis and lung metastasis (x2 =5.48,4.02,5.07 and 5.19,all P＜0.05).The positive percentage of CCL20 expression was significantly correlated to tumor maximum diameter and pTNM stage (x2 =4.09 and 4.00,both P＜0.05).Both the disease-free survival (DFS) rate and overall survival (OS) rate of CCR6-positive group were significantly lower than those of negative group (x2 =4.57 and 6.57,both P＜ 0.05).There were no significant differences in DFS rate and OS rate between CCL20-positive group and negative group (both P＞0.05).Conclusion CCR6/CCL20 axis may be related with the malignant behavior and the prognosis of HCC.

Objective: To investigate the detection rates and inlfuencing factors of atrial septal defect (ASD) and ventricular septal defect (VSD) among neonates in two cities of East China and to provide scientiifc basis for the prevention, diagnosis, treatment and monitor of ASD and VSD. Methods: 2100 newborns with gestational age of at least 28 weeks were recruited consecutively from each city between 2013-09 and 2014-11. Data related to ASD and VSD were collected by questionnaires and echocardiographic screening was conducted within 7 days after birth. Results: A total of 4152 neonateswere examined with gestational age of (39.03 ± 1.29) weeks, among whom 2189 were male infants (52.72%), and age of mother was (26.32 ± 4.10) years old. Detection rates of ASD and VSD were 60.5‰ and 12.8‰ respectively, showing no significant difference between genders (P>0.05). Multivariate logistic regression analysis showed that maternal pre-pregnancy BMI and home decoration were the inlfuencing factors of ASD and maternal drug use in early pregnancy was the inlfuencing factor of VSD among newborns. Conclusions: Detection rates of ASD and VSD among neonates were relatively high in two cities of East China. Early screening is importtant to reduce the incidence of ASD and VSD and improve the prognosis.
