Objective In a large-scale clinical medical examination, A2 type best multiple-choice test questions to the same knowledge were used respectively in simple and complex form, to compare the difficulty and discrimination indices of the two forms of test questions and provide evidence to the improve-ment of clinical medical examination. Method In a large-scale clinical medical examination more than 4000 candidates participated, and 20 questions to different knowledge points were randomly selected and used in the examination respectively in simple and complex A2 type best multiple-choice test questions. The difficulty and discrimination indices of the two forms of test questions were compared. Results The average difficulty coefficient of the 20 simple test questions (65.5 words per question in average) is 0.6829, and the average discriminative powers are 0.2675 and 0.2579 respectively using identification index method and point biserial correlation method. The average difficulty coefficient of the 20 complex test ques-tions (135.5 words per question in average) is 0.7095, and the average discriminative powers are 0.3065 and 0.2967 respectively using identification index method and point biserial correlation method. Conclusion To the same knowledge points, the average difficulty of complex A2 type best multiple-choice test questions is slightly lower than the simple ones, while the average discriminative power is increased in the complex questions. The complex A2 type test questions are of higher quality and more in line with the requirements of the medical entrance examination, medical education and examination reform.

Objective To investigate the role of endoscopic ultrasonography (EUS) in diagnosis and treatment of colorectal submucosal lesions. Methods EUS were applied in 74 patients with suspected colorectal submucosal lesions. According to the origin of submucosal lesion, the patients had received biopsy, endoscopic ultrasonography-fine needle aspiration (EUS-FNA) and endoscopic treatment or surgery. The correlation between EUS and clinical pathology is analyzed retrospectively. Results In the diagnosis based on EUS, there were 28 cases of neuroendocrine tumors (occurred in the rectum), 15 lipomas (4 cases occurred in ileocecal, 1 in transverse colon, 8 in ascending colon, 2 in sigmoid colon), 2 rectal gastrointestinal stromal tumor (1 in muscularis propria and the other in muscularis mucosa), 14 external pressure changes (9 ovarian tumor, 2 lymph nodes, 3 pelvic tumor), 5 cyst (4 in transverse colon, 1 in ascending colon), 1 gas cyst, 3 sigmoid colon endometriosis, 4 rectum malignant tumor invasion, 2 intestinal lymphoma. All the patients had received biopsy, EUS-FNA, endoscopic treatment or surgery. Compared with pathology, a total coincidence rate of 91.9% (68/74) was achieved by EUS, and 2 cases were pathologically diagnosed as leiomyoma, which is considered as rectal carcinoma by EUS at first, 1 case of intestinal lymphoma instead of lipoma, 2 inflammatory mass instead of malignant tumor around the rectum, and 1 rectal carcinoma instead of endometriosis. Conclusion The digestive tract structure could be showed clearly with EUS, and the size of the colon and rectal submucosal lesions, the layer of origin and the structural relationship of adjacent tissues could also be detected. Then, the appropriate treatment against the colon and rectal submucosal lesions would be adopted after the accurate judgment of lesions with EUS.

Objective To study the changes of anorectal motility and rectal sensation in the elderly patients with ulcerative colitis (UC). Methods The anorectal motility and rectal sensation were investigated by Medtronic PC-Polygraf HR made by Sweden in 35 non-elderly patients versus 19 elderly patients with UC, and 20 non-elderly healthy subjects (HS) and 28 elderly HS were as control group. Results (1) The static pressure, pressure of anal sphincter and the maximal squeeze pressure of anal sphincter in non-elderly patients and elderly patients with UC showed no significant differences compared with those in non-elderly HS and elderly HS group (elderly patients with uc vs. ederly HA:t= 1.311,1.298,1.401;nonederly patients with uc vs. nonederly HS: t=1.294,1.299,1.322all P>0.05). When abdominal pressure was increased, the net increased pressure of anal sphincter was (2.8±1.1) kPa in the elderly patients with UC, (2.9±1.3) kPa in the non-elderly patients with UC. The pressures were lower in two UC groups than in HS groups [elderly HS group:(3.8±1.2) kPa; non-elderly HS group:(3.9±1.2) kPa,elderly patients with uc vs. ederly HS:t=2.238,nonelderly patients with us vs. nonederly HS:t=2.243 all P<0.05]. (2)The rectal lowest volume of sensory threshold, the maximal volume of tolerance and the maximal compliance were (85±30) ml, (180±69) ml, (26. 5±8.8) ml/kpa in elderly patients with UC and (65±15) ml, (170±58) ml, (22.6± 10. 3) ml/kPa in non-elderly patients with UC. They were lower than in each HS group [elderly HS group (95±31) ml, (205±78) ml, (32.9±12.9) ml/kPa; non-elderly HS group:(78±38) ml, (190±50) ml, (30.8± 15.2) ml/kpa, all P<0. 01]. (3)The rectal lowest volume of sensory threshold, the maximal volume of tolerance and the maximal compliance in elderly patients with UC were higher than in non-elderly patients with UC (elderly patients with uc vs. elderly HS:t=3. 121,3. 135,3.146,nonederly patients with uc vs. non elderly HS: t= 3.162, 3.141, 3.188 elderly patients with uc vs. nonelderly patients with uc: t = 2. 246,2. 239,2. 240 all P< 0. 05). The rectal lowest volume of sensory threshold, the maximal volume of tolerance in elderly HS group were higher than in non-elderly HS group (ederly HS vs. t = 2. 328,2. 301 all P<0. 05). Conclusions There are some anorectal motility disturbances in UC. Higher sensitivity, lower tolerance, lower compliance of rectum and weakened anal automatic control function in UC may be associated with diarrhea and frequent defecation. The rectal sensation threshold to volume stimulus is higher in elderly HS than in non-elderly HS group. The sensibility to volume ectasis of rectum is weakened and the survivability of rectum is increased in elderly patients with UC.

Advanced schistosomiasis is the most serious clinical type of schistosomiasis. Its diagnosis and treatment are relat?ed to many special departments,such as gastroenterology,general surgery,neurology,endocrinology,radiology,traditional Chinese medicine,blood purification,endoscopy,intervention,and ICU. It is necessary to apply a multidisciplinary treatment (MDT)mode. However,the mode has no universal standard and guide in practice. It is very important for the implementation of MDT mode of advanced schistosomiasis to form a treatment expert team,formulate the formal working procedures,and standard?ize the treatment schedules. The standardized implementation of MDT mode will be important to provide a more effective clinical decision on advanced schistosomiasis.

Objective:To investigate the effects of hydrogen rich-saline (HRS) on intestinal mucosal barrier in rat with intestinal ischemia/reperfusion injury (IIRI).Methods:Twenty-four healthy male Sprague-Dawley rats, aged 8 weeks, were randomly divided into 3 groups (8 in each group) by random number table method: sham group, model group and HRS group.Rats in HRS group were intraperitoneally injected with HRS (10 mL/kg) at 30 min of ischemia, and the same amount of normal saline was intraperitoneally injected in model group.After 45 min of ischemia and 6 h of reperfusion, rats were sacrificed.Serum and ileum were collected for further detection.Tumor necrosis factor alpha (TNF-α), interleukin (IL)- 1β and IL-17A expression levels in serum were detected by conducting enzyme-linked immunosorbent assay (ELISA). The localization expressions of tight junction protein Occludin was detected by immunohistochemical staining (IHC), while the localization expression of tight junction protein zonula occluden-1 (ZO-1) were detected by immunofluorescence staining (IF). The protein expression of Occludin, ZO-1, and Lysozyme were detected by performing Western blot.The mRNA expression of Lysozyme and α-defensin were detected by real-time PCR (qPCR).Results:ELISA results proved that the levels of serum TNF-α and IL-1β in HRS group rats were significantly lower than those in model group [(62.02±29.97) ng/L vs.(113.40±44.58) ng/L, (21.68±0.35) ng/L vs.(28.29±3.49) ng/L], while the level of IL-17A increased [(28.18±5.28) ng/L vs. (15.10±3.60) ng/L] (all P<0.05). IHC staining: compared with model group, the expression of Occludin in HRS group was uniform and continuous, and the staining was darker.IF results: compared with model group, the fluorescence signal intensity of ZO-1 in HRS group rats significantly increased, and the distribution was clear and continuous.Wes-tern blot results: compared with model group, the expression levels of Occludin and ZO-1 proteins in HRS group rats remarkably increased (0.79±0.06 vs. 0.54±0.04, 0.91±0.11 vs. 0.51±0.13), while Lysozyme protein decreased (1.50±0.40 vs. 2.99±0.80) (all P<0.05). qPCR results revealed that the expression level of Lysozyme mRNA in HRS group rats was lower than that in model group (1.64±0.33 vs. 2.20±0.40), while α-defensin mRNA obviously increased (0.82±0.19 vs. 0.47±0.13) (all P<0.01). Conclusions:HRS protects intestinal mucosal barrier by inhibiting the expression of tight junctions and the secretion of antimicrobial peptides in rat suffering from IIRI.
