OBJECTIVE To explore the possible mechanism of Qingchang Huashi Formula in the treatment of ulcerative colitis(UC).METHODS Fifty C57BL/6 male mice were randomly divided into a control(Ctrl)group,a model group,a low-dose Qingchang Huashi Formula group,a high-dose Qingchang Huashi Formula group,and a 5-aminosalicylic acid(5-ASA)group based on body weight.The UC model was established in mice by drinking 3%dextran sulfate sodium(DSS)for 6 d.On d7 and d8,DSS was withdrawn and ultrapure water was given daily.Ultrapure water or different drugs were administered orally throughout the experiment:Ctrl and model groups received 0.2 mL of ultrapure water,while the low-dose and high-dose Qingchang Huashi Formula groups re-ceived 6 and 12 g·kg-1,respectively,and the concentration of 5-ASA was 100 mg·kg-1.Body weight and fecal characteristics of the mice were recorded daily,and the experiment ended on d9.Serum was collected from mice for serum metabolomics and inflam-matory factor expression analysis.The colons of the mice were isolated and their lengths were measured,and the distal colon was ob-tained for pathological analysis.The livers and colons of the mice were isolated for subsequent total bile acid analysis.RESULTS Compared with the Ctrl group,the model group mice showed a significant decrease in body weight and colon length(P<0.000 1),a remarkable increase in disease activity index(P<0.000 1).The concentration of inflammatory factors IL-1β and TNF-α was signifi-cantly increased(P<0.000 1).High-dose and low-dose Qingchang Huashi Formula,as well as 5-ASA could significantly alleviate the loss of body weight,increased DAI,colon shortening,and disappearance of colon tissue morphology in mice.Through ELISA tes-ting,it was found the concentration of IL-1β and TNF-α was remarkably decreased after Qingchang Huashi Formula and 5-ASA treat-ment(P<0.01,P<0.000 1).Through LC-MS analysis of serum metabolites and KEGG enrichment analysis,we found that interven-tion with Qingchang Huashi Formula could significantly affect the primary bile acid synthesis,secondary bile acid synthesis and bile se-cretion.Using total bile acid reagent kit,we found that the total bile acid in the liver of colitis mice did not show significant changes when compared with the Ctrl group of mice,and the concentration of total bile acid in the serum was significantly reduced,the concen-tration of TBA in the colon was significantly increased(P<0.05).After intervention with the Qingchang Huashi Formula,the concen-tration of total bile acid in the serum of mice was significantly increased,while the concentration of total bile acid in the colon was re-duced(P<0.05).Compared with mice in Ctrl group,the levels of deoxycholic acid(DCA)and taurine deoxycholic acid(TDCA)in serum of colitis mice were significantly reduced(P<0.05).After intervention with Qingchang Huashi Formula,the levels of DCA,TD-CA and Ursodeoxycholic acid(UDCA)in serum of mice were restored(P<0.01).CONCLUSION Qingchang Huashi Formula can effectively relieve DSS-induced colitis in mice,reducing immune inflammatory response,reregulating the disorder of serum metabolism and enterohepatic circulation.

Objective To promote the objectification and intelligence of clinical TCM tongue diagnosis in ulcerative colitis(UC).Methods Daosheng DS01-B tongue and face diagnosis information collection system was used to prospectively collect tongue image pictures of patients with ulcerative colitis damp-heat in the large intestine syndrome(DCSR)and spleen deficiency dampness retention syndrome(PXSY),with totaling 1096 images.After UC tongue image segmentation,preprocessing,and data augmentation,a data set of UC tongue images was formed.Based on ResNet50,a UC tongue image classification model was constructed using feature fusion methods and attention modules.Results The UC tongue image classification model constructed had better classification performance,with an average F1 value of 85.09%,an AUC value of 0.83 for PXSY,and an AUC value of 0.81 for DCSR,both of which were higher than the VGG11 and ResNet50 models.Conclusion The constructed UC tongue image classification model can effectively identify DCSR and PXSY,providing a new approach to improve the accuracy and objectivity of UC differentiation and assisting in the intelligence of TCM tongue diagnosis.

OBJECTIVE To investigate the therapeutic effect of Qingchang Huazhuo Formula(QCHZF)on mice with ulcerative colitis(UC)and the influences of fecal metabolites based on non-targeted metabolomics to investigate the mechanism of action of QCHZF in the treatment of UC.METHODS UC mice were induced by dextran sulfate sodium salt(DSS)and were administered with QCHZF.During the experiment,the body weight,stool characteristics and blood in stool were recorded daily,and the disease activity index(DAI)was calculated.At the end of the experiment,the length of colon was measured,colonic tissue damage in mice were ob-served by hematoxylin-eosin and alcian blue staining,mRNA expression levels of inflammatory factors,IL-6,IL-18 and IL-1β,and intestinal barrier factors,ZO-1 and Muc2,were detected in colon tissues via qPCR method,and protein expression level of intestinal barrier,Muc2,was detected with immunofluorescence.Fecal metabolite changes in mice were detected employing un-targeted metabo-lomics and analyzed by MetaboAnalyst 5.0 for metabolic pathway enrichment.RESULTS QCHZF significantly alleviated colitis symptoms,increased body weight,decreased DAI score,reversed colonic shortening,inhibited inflammatory factors expression,im-proved colonic tissue structure disorders,increased the number of goblet cells,and restored the intestinal barrier in UC mice,regulated 58 metabolites,mainly involving pathways of methionine and cysteine metabolism,purine metabolism,steroid hormone biosynthesis,vitamin B6 metabolism,tryptophan metabolism and primary bile acid pathways.CONCLUSION QCHZF can improve colitis symp-toms,repaire the intestinal barrier and modulate fecal metabolites and related metabolic pathways in UC mice.

Objective:To scientifically measure and morphologically evaluate the anatomical shape of the skin in the first web space based on cadavers, and to guide the design of flap in this area.Methods:Sixteen human cadavers fixed with 10% formaldehyde without injury or deformity on the hand were selected in the Department of Hand Surgery, the Third Hospital of Suqian. According to the characteristics of the first web area, marker points were selected for measurement and morphological observation. Morphological characteristics of the first web with thumb radial abduction(r) or palmar abduction(p) were measured and compared. The t-test was used for statistical analysis. P<0.05 was considered statistically significant. According to the results of measurement, standardised shapes and parameters of the skin were obtained for flap repair of defect of the first web. Results:When the thumb was in palmar abduction, the maximum distance [a(p)] of the first web of female(F) and male(M) was 5.78/8.42 cm(F/M), and the skin [S(p)] was 17.09/23.63 cm 2(F/M), both were significantly greater than the distance [a(r)] at 4.86/6.28 cm and the area of skin area [S(r)] at 14.39/20.15 cm 2 when thumb was in the radial abduction position( P<0.05). There was no significant difference in the length of [b(r)] and [b(p)] alone the long axis of flap between palmar and radial abductions(7.54/9.38 cm and 7.34/9.74 cm, respectively) of the thumb( P>0.05). It was found that the area of first web was not shaped as a symmetrical spindle, but an irregular quadrilateral inclined to the index finger. Conclusion:Design and measurement of a flap for the first web space should take the maximum palmar abduction of a thumb as a reference. The asymmetric quadrilateral flap design is more in line with the anatomical and characteristics in the region.

OBJECTIVE：To evaluate the benefit and risk of tirofiban in the treatment of acute coronary syndrome （ACS），and to provide evidence-based reference for clinical drug selection and decision. METHODS ：Retrieved from domestic and foreign database as PubMed ，the Cochrane Library ，CNKI and Wanfang database ，during the establishment of database to Apr. 2020，two researcher independently screened the literature based on inclusion and exclusion criteria and extracted the data. After the quality evaluation of the included literatures ，based on rapid health technology assessment ，the extracted results were classifiedly evaluated and comprehensively analyzed. RESULTS ：A total of 13 researches of systematic review/Meta-analysis and 1 research of pharmacoeconomics were included. Compared with placebo ，tirofiban could significantly reduce all-cause mortality [OR ＝0.68， 95％CI（0.54，0.86），P＝0.000 1] and the incidence of major adverse cardiac events （MACE）in patients with ACS [RR ＝0.24， 95％CI（0.14，0.40），P＜0.01]，and increased the incidence of TIMI 3 [OR＝5.73，95％CI（2.99.10.97），P＜0.01]. Tirofiban and eptifibatide had similar therapeutic efficacy in the treatment of ACS ，but tirofiban significantly increased the risk of TIMI small bleeding in patients with ACS [RR ＝0.61，95％CI（0.38，0.98），P＝0.04]. For ACS patients with non-ST elevation （NSTE-ACS）， compared with placbo ，tirofiban significantly reduced the incidence of MACE [RR ＝0.76，95％ CI（0.61，0.96），P＝0.018]，but significantly increased the risk of bleeding [OR ＝1.49，95％CI（1.12，1.98），P＝0.006]，while there was no significant difference in its effects on the all-cause mortality of NSTE-ACS patients （P＞0.05）. For STEMI patients ，compared with placebo ，tirofiban significantly reduced the all-cause mortality [RR＝0.61，95％CI（0.35，1.05），P＝0.007] and the incidence of MACE [RR ＝0.63，95％ CI（0.44，0.90），P＝0.007]. When combined with liposuction ，tirofiban also significantly reduced the incidence of MACE [RR ＝ 2.05，95％CI（1.71，2.46），P＜0.01]，and significantly increased the incidence of TIMI 3 [OR＝3.18，95％ CI（2.4，4.22），P＜ 0.01]，but there was no significant difference in its effects on bleeding risk （P＞0.05）. The included pharmacoeconomic study showed that patients treated with bivalutine could get 10.07 QALYs，patients treated with heparin combined with tirofiban could get 9.98 QALYs，and the incremental cost-effectiveness ratio bivalutine compared to the latter one was 28 575.77 yuan/QALYs，which was lower than 3 times of the per capita GDP of some cities. CONCLUSIONS ：Tirofiban has good efficacy in the treatment of ACS，but it can increase the risk of bleeding than eptifibatide and placebo. Domestic bivalirudin treating for ACS has a cost-effectiveness advantage over tirofiban combined with heparin.
