ABSTRACT
Background:In recent years, the incidence of ulcerative colitis (UC) has increased year by year in China, and the number of elderly patients with UC is growing significantly.However, the difference in clinical characteristics between elderly and non-elderly UC patients was not fully clarified.Aims:To investigate the difference in clinical characteristics between elderly and non-elderly UC patients.Methods:A total of 163 UC patients admitted from Jan.2012 to Jun.2015 at the Affiliated Jiangyin Hospital of Southeast University Medical College were retrospectively recruited and divided into elderly group (no less than 60-year-old, n=32) and non-elderly group (less than 60-year-old, n=131) according to the age of onset.The clinical data were collected, and the general conditions, clinical manifestations and extent of the disease were compared between the two groups.Results:There were no significant differences in gender, family history of inflammatory bowel disease, history of smoking and appendectomy between elderly and non-elderly groups (P>0.05).Hematochezia and mucous bloody stool were less prevalent in elderly group than in non-elderly group (P0.05).More extraintestinal manifestations were seen in non-elderly group, but the difference was not statistically significant (P>0.05).Lesions in elderly group mainly located in left hemicolon, while pancolitis was predominant in non-elderly group (P<0.05).Conclusions:In elderly patients with UC, hematochezia and mucous bloody stool are not frequently seen, and the disease is not extensive and mainly located in left hemicolon.
ABSTRACT
Objective:To investigate the effects of icaritin(ICT)on the proliferation and osteogenic differentiation of rat bone mar-row stromal cells(rBMSCs).Methods:rBMSCs were cultured from the bone marrow of SD rats and identified by multilineage differ-entiation assays.3,6 and 9 days after the treatment of rBMSCs of passage 4 by ICT at 1 0 -9 ,1 0 -8 ,1 0 -7 ,1 0 -6 and 1 0 -5 mol/L re-spectively,the proliferation and differentiation of the cells were examined by cck-8 and alkaline phosphatase (ALP)activity assay kit respectively.The calcium nodule formation was observed by alizarin red(AR)staining 21 days after 1 0 -9 mol/L ICT treatment. Results:Primary rBMSCs showed the typical spindle-like shape with attachment growth.rBMSCs could be induced to osteogenic and adipogenic differentiation.The proliferation of rBMSCs was inhibited but ALP activity was enhanced by ICT.1 0 -9 mol/L ICT in-cresed calcium nodule formation.Conclusion:ICT can dose-dependently inhibit the proliferation,but promote the osteogenic differ-entiation of rBMSCs.
ABSTRACT
Inflammatory bowel disease(IBD),including ulcerative colitis(UC)and Crohn’s disease(CD),is characterized by chronic non-specific inflammation of intestinal tract,which is incurable and easily relapsing. Recently,the role of gut microbiota in IBD has become a hot spot of study. This article reviewed the advances in study on intestinal microbiota in intestinal homeostasis and IBD.
ABSTRACT
Objective To study the effect of the Aiyishu injection combined with chemotherapy for middle and advanced cancer patients in the near future curative effect and survival quality.Methods 127 middle and advanced cancer patients were randomly divided into two groups,71 cases in therapeutic group and 56 cases in control group.The therapeutic group and control group both choose the same sickness plants and combined chemotherapy plan of pathology,therapeutic group added the Aiyishu injection 40 ml to drip. The treatment course lasted 14 days,with 3～4 courses,Simple chemotherapy was used in the control group. Results In the therapeutic group,there were 3 cases of complete response(CR),23 cases,of partial response (PR),the rate of response is 36.62 %(26/71).In the control group,there was 1 case of complete response(CR), 10 cases of partial response(PR),the rate of response is 19.64 %(11/56).There was significant difference be- tween the two groups(P0.05),whereas it declined significantly in the control group after chemotherapy(P
