Objective:To discuss the role of Fas/FasL-mediated colonic epithelial apoptosis in the pathogenesis of ulcerative colitis(UC).Methods:Expression of Fas,FasL and M30(a new epithelium apoptosis marker) antigen on colonic mucosa of 35 patients with UC and 15 control populations were detected by IHC.Each marker was analyzed by image analysis system.Co-expression of Fas and M30 was observed through serial sections and double staining IHC.Results:The expression of Fas,FasL as well as M30 in UC increased considerably compared with controls (P

OBJECTIVE: To study the effect of samples having different pH values in the bacterial endotoxins test (BET). METHODS: The BET was conducted as an assay of the concentration of endotoxins by using kinetic-turbidimetric technique. Samples having different pH values but containing same concentration reference standard endotoxin (RSE) were tested by TAL/LAL reagents. The average result on the standard curve was calculated and the mean recovery observed. RESULTS: The reagents had three highly sensitivities in pH 5.20, pH 7.83/pH 6.23 and pH 10.55. After adjustment to pH 6 to 8, the mean recovery was 76.5%～115.9% or 85.8%～99.8%. When the sample pH value was less than 3 or more than 12, the test was unsuitable for the inhibition test, and the mean recovery was less than 56.8%. CONCLUSION: It is necessary to adjust the pH of the solution to be tested in the BET, adjust the sample to pH (6.5～7.5) when using TAL reagents, and adjust to pH (6.2±0.1) or pH(6.7～7.8) when using LAL reagents.

Objective To explore influence of antibiotics and Jiuyi Dan combined with incision-thread-drawing procedure on perianal abscess patients' level of activin A (ACTA) and C-reactive protein (CRP).Methods120 cases of perianal abscess patients in our hospital during March 2015 to December 2016 Coloproctology were selected, they were divided into the experiment group and the control group by random number method.All of patients were taken incision-thread-drawing procedure.Then the experimental group were given nine one antibiotics and Jiuyi Dan, the control group were given antibiotics.The cure rate, 6months after the recurrence rate, average healing time of the wound, and wound edema rate of two groups were observed.Levels of ACTA and CRP expression levels of two groups of patients before and after operation were analyzed.ResultsPatients in the experimental group cure rate was 96.7% higher than that of the control group (P<0.05), the recurrence rate of patients in the experimental group than in the control group, the difference was not statistically significant;the patients in the experimental group the average healing time was (20.67±3.22) d shorter than the average healing time of patients in the control group (29.48±3.15) d, patients in the experimental group wound edema rate of 5% was significantly lower than in the control group 20% (P<0.05);3D ACTA, the expression level of CRP was significantly higher than the preoperative 7 d levels after operation in the two groups (P<0.05);after 7d, the expression level of the two groups of patients with ACTA and CRP were significantly lower than the preoperative level of expression of 7d (P<0.05), experimental group levels of ACTA were significantly lower than the control group, the difference was statistically significant (P<0.05);postoperative 14d patients, ACTA levels of two groups were significantly lower than the levels before operation (P<0.05).ConclusionPerianal abscess can be treated effectively and patients levels of Acta and CRP were obviously dereased by Jiuyi Dan combined with incision-thread-drawing procedure combined, postoperative inflammatory reaction could be importantly alleviated, it was worth clinical promotion.

Objective To investigate the clinical characteristics of juvenile rectal carcinoma in order to improve the diagnostic level and therapeutic efficacy at the early stage. Methods Clinical data, including clinical manifestations, misdiagnosis, clinical pathology, treatment, and prognosis, from 89 cases of juvenile rectal carcinoma were analyzed retrospectively and compared with those from 440 cases of senile rectal carcinoma. Results ① The main manifestations of juvenile rectal carcinoma included anal and rectal pains, abdominalgia, abdominal distention, and sacrococcygeal pain. ② In juvenile group, carcinomas with distance less than 9 cm and less than 7 cm away from the anal verge amounted to 92.13% and 69.66%, respectively (average distance: 5.43 cm). ③ The average period of misdiagnosis in juvenile group was 5.7 months with a misdiagnosis rate of 97.75%, significantly higher than that in senile group ( P

Objective To investigate the regulating effect of Jianpixiaoshi Decoction(JPXSD)on gastrointestinal motility in rats of functional dys-pepsia(FD)with spleen deficiency syndrome. Methods Forty healthy male SD rats were randomly divided into four groups:normal control group, model group,model traditional Chinese medicine(TCM)group and model western medicine group. Except for the normal control group,FD model of spleen-deficiency type was established by swimming to exhaustion on alternate days and alternating feeding of cabbage and lard for 25 days. Corre-sponding drugs were then administrated to those four groups:distilled water,JPXSD and Mosapride distilled water solution once a day by gavage for 7 days. Symptoms and body weights of these rats were observed and recorded during the experiment. After the last of drug administration,all groups were fasted for 24 hours. Nutritious semisolid paste marked with ink was given orally to the rats,GER and IPR of 1 hour were detected under anesthe-sia by sodium thiopental and blood were collected at the same time. The concentration of serum SP and SS were measured by ELISA according to the instructions. Results JPXSD improved the symptoms of model rats. Model TCM group showed significantly increased body weight,higher GER, lower IPR,higher serum SP level and lower SS level when compared to model group(P<0.05). Conclusion JPXSD could improve the symptoms of rat with spleen-deficiency,raise its body weight,accelerate the decreased gastric emptying and bring back the hyperactive small intestinal move-ment to normal. The regulating role of JPXSD may be realized through the increase of serum SP level and decrease of SS level.

One hundred and sixteen cases of vertebral artery type of cervical spondylopathy were treated by electroacupuncture on Fengchi (GB 20) and Jiaji (Ex-B 2, C2-5), cupping plus manipulation of pulling the rotated neck. The result showed 89 cases were cured, 21 cases were improved and 6 cases failed with the total effective rate of 94.8%.

Delayed cerebral vasospasm is the leading cause of death in patients with subarachnoid hemorrhage. A good in vivo animal model of cerebral vasospasm after subarachnoid hemorrhage helps to understand the occurrence, development of this cerebral vasospasm, and the complicated and various pathophysiological mechanisms. It will provide important information for clinical interventions
