Objective To evaluate the nasointestinal decompression intubation in acute small intestinal obstruction. Methods Ten patients with acute small bowel obstruction received nasointestinal decompression intubation under x-ray guidance. The nasointestinal decompression tube passing over a guidewire was inserted into small intestine near Tres ligament or further down distally with assistance of patients adopting in multi-physical positions. Results The intubation of nasointestinal decompression tubes into small intestine was technically successful in all patients with average procedural time of 16 min.(10 ～ 35 min). After placement of the tube, all patients obtained various degrees of symptoms relief including abdominal pain, distention, vomiting, etc. Four patients with simple adhesive obstruction recovered completely and the tube was removed 2 weeks later. Three patients were refered to surgical operation, and 3 others gave up for further treatment. There were no complications such as bleeding or perforation related to intubation. Conclusion Nasointestinal decompression intubation under guidance of X-ray is rather simple, less time consuming, especially with high efficiency for preoperative gastrointestinal decompression and treating simple adhesive bowel obstruction; ought to be recommended.

Objective: To explore the relationship between eHealth literacy and illness behavior of vocational college students in Jinan city,and to provide reference for improving health education in vocational colleges. Methods: In December 2019, 1 157 college students from 4 vocational colleges in Jinan city were selected to conduct eHealth literacy and illness behavior survey. Results: The score of eHealth literacy was(29.92±8.36),and the score of illness behavior was(52.82±18.04). Illness behavior score of male students was lower than female students,urban students was higher than the rural students,only children lower than the non-only children,those who did not serve as student leaders were lower than those who were served,those with paternal education lower than high school were lower than those with paternal education higher than high school,and those differences were statistically significant (t=-10.82,2.29,-3.85,-3.99,-4.89,P<0.05). The score of eHealth literacy of male students was lower than that of female students,that of urban students was higher than that of rural students,that of only children was lower than that of non-only children,that of student cadres was higher than those who do not,and the differences were statistically significant (t=-3.16,2.87,-3.32,-2.91,P<0.05). The total score and dimensions of eHealth literacy were significantly positively correlated with total score and dimensions of illness behavior (r=0.09-0.27,P<0.01),and eHealth literacy significantly positively predicted illness behavior (β=0.15,P<0.01). Conclusion eHealth literacy is an important factor affecting the illness beahvior of college students in vocational colleges, more attention should be paid to the cultivation of eHealth literacy of vocational college students to improve their illness behavior.

Objective To investigate the expressions of P53,topoisomeraseⅡ(TopoⅡ)and multidrug resistance associated protein(MRP)in tissues of colorectal cancer of patients combined with chronic schistosomiasis.Method The retrospective case-control study was adopted.The clinicopathological data of 338 colorectal cancer patients who were admitted to the Zhejiang Cancer Hospital between January 2008 and December 2010 were collected.Cancer tissue specimens from surgical resection were collected.Among 338 patients,80 were combined with chronic schistosomiasis and 258 were combined with non-chronic schistosomiasis.The expressions of P53,TopoⅡand MRP were dectected using immunohistochemistry(IHC).Ranked data were presented as percentage and analyzed using the non-parametric test.Results The negative,weak positive,positive and strong positive expressions of P53 were respectively 5.00％(4/80),87.50％(70/80),3.75％(3/80),3.75％(3/80)in tissues of colorectal cancer of patients combined with chronic schistosomiasis and 28.68％(74/258),19.38％(50/258),16.67％(43/258),35.27％(91/258)in tissues of colorectal cancer of patients combined with non-chronic schistosomiasis,with a statistically significant difference(Z=-2.962,P＜0.05).The negative,weak positive,positive and strong positive expressions of TopoⅡwere respectively 8.75％(7/80),51.25％(41/80),22.50％(18/80),17.50％(14/80)in tissues of colorectal cancer of patients combined with chronic schistosomiasis and 12.01％(31/258),55.43％(143/258),22.48％(58/258),10.08％(26/258)in tissues of colorectal cancer of patients combined with non-chronic schistosomiasis,with no statistically significant difference(Z=-1.551,P＞0.05).The negative,weak positive,positive and strong positive expressions of MRP were respectively 7.50％(6/80),40.00％(32/80),28.75％(23/80),23.75％(19/80)in issues of colorectal cancer of patients combined with chronic schistosomiasis and 24.42％(63/258),38.37％(99/258),24.03％(62/258),13.18％(34/258)in tissues of colorectal cancer of patients combined with non-chronic schistosomiasis,with a statistically significant difference(Z=-3.408,P＜0.05).Conclusion There are abnormal expressions of P53 and MRP in tissues of colorectal cancer of patients combined with chronic schistosomiasis,which may be involved in the hypothetical mechanism of chronic schistosomiasis inducing carcinogenesis of colorectal cancer.

OBJECTIVETo investigate the expression difference of DNA mismatch repair gene hMLH1 and hMSH2 between schistosomiasis-associated colorectal cancer and sporadic colorectal cancer.

METHODClinical and pathological data of colorectal cancer patients receiving operations in Zhejiang Cancer Hospital between January 2008 and December 2010 were retrospectively analyzed. Patients were divided into schistosomiasis group(n=80) and sporadic group (n=258) according to the preoperative history and pathologic results. Pathological specimens were collected and tissue chips were made to analyze the expression of hMLH1 and hMSH2 by immunohistochemistr.

RESULTSCompared with sporadic group, older age [(62.2 ± 9.6) year vs. (57.2 ± 11.7) year, P=0.000)], lower platelet level [(197.0 ± 59.6) × 10(9)/L vs. (217.0 ± 84.3) × 10(9)/L, P=0.02] and lower WBC level [(5.9 ± 1.9) × 10(9)/L vs. (6.6 ± 2.8) × 10(9)/L, P=0.02] were found in schistosomiasis group. Ratio of low differentiation-undifferentiation tumor was significantly higher in schistosomiasis group [44.2% (34/77) vs. 4.9% (12/247), P<0.05]. Lower positive rate of hMLH1 expression [77.5% (62/80) vs. 98.1% (253/258), P=0.000] and hMSH2 expression [75.0% (60/80) vs. 95.3% (246/258), P=0.000] was found in schistosomiasis group compared with sporadic group. Concurrent schistosomiasis was one of the risk factors of hMLH1/hMSH2 deficiency (RR: 0.913, 95% CI: 0.836-0.997, P=0.043), but not an independent factor (RR: 0.951, 95% CI: 0.867-1.043, P=0.286).

CONCLUSIONSchistosomiasis is associated with lower positive expression of hMLH1 and hMSH2, which indicates that hMLH1/hMSH2 deficiency may be a potential mechanism of schistosomiasis inducing carcinogenesis of colorectal cancer.
