ObjectiveTo explore the effect of Qingre Huayu Jianpi prescription （QHJ） on colitis-associated colorectal cancer （CAC） in mice， and its related mechanism. MethodC57BL/6 mice were randomly divided into four groups including the normal， model， QHJ low-dose （QHJ-L， 10 g·kg-1）， and QHJ high-dose （QHJ-H， 40 g·kg-1） groups. Azoxymethane （AOM） and dextran sodium sulfate （DSS） were combined to chemically build a CAC mouse model for 14 weeks. Each drug group was given intragastrically from the 5th week to the 14th week， once per day. An equal volume of water was fed to the normal and model groups. The mouse survival rate， colon length， weight， and pathological alterations were assessed. The protein expressions of Wnt-3a protein signaling （Wnt3a）， β-catenin， Non-phosphor-β-catenin （Non-p-β-catenin）， and cholesterol-binding glycoproteins 133 （CD133） were detected by Western blot. The localization and expression of the cluster of differentiation （CD） 80 and CD11 antigen-like family member B （CD11b） were detected by immunohistochemistry （IHC）. The colon organoids derived from CAC mice were isolated and cultured to detect the expression of Wnt signaling pathway-related proteins. ResultThe survival rate of the CAC mice was improved by QHJ treatment and the number of colon tumors was inhibited significantly. Compared with those in the normal group， the expression levels of Wnt3a， β-catenin， Non-p-β-catenin， and CD133 in colon tissues in the model group were significantly increased （P<0.05， P<0.01）. Compared with those in the model group， the levels of Wnt3a and β-catenin in the QHJ-L group were significantly decreased （P<0.01）， and the protein levels of Wnt3a， β-catenin， Non-p-β-catenin， and CD133 in the QHJ-H group were significantly decreased （P<0.05， P<0.01）. Meanwhile， the expression level of CD11b in the model group was significantly increased compared with that in the normal group while the CD80 level was significantly decreased （P<0.05， P<0.01）. Compared with those in the model group， CD11b in QHJ-L and QHJ-H groups was significantly decreased， and CD80 was significantly increased（P<0.05， P<0.01）. The expressions of Non-p-β-catenin and CD133 in colonic organoids of CAC model mice were significantly increased， while QHJ treatment could inhibit the expressions of Non-p-β-catenin and CD133 in colonic organoids （P<0.01）. ConclusionQHJ could inhibit the inflammation-cancer development in CAC mice， the mechanism of which might be related to regulating the microenvironment and inhibiting the over-activation of Wnt signaling.

Objective To evaluate the clinical effect of Tissue-Link combined with Cusa and Pringle in hepatectomy for primary hepatocellular carcinoma. Methods From January 2013 to January 2017,the clinical data of ninety-six primary hepatocellular carcinoma patients who had received hepatectomy were collected. 45 cases of hepatectomy (control group) were performed by Pringle. The other 51 cases (observation group) were treated with Tissue-Link combined with Cusa. The indexes and survival rates were compared between the two groups during and after operation. Results Compared with the control group, the operation time of the observation group was prolonged ((189. 2±45. 8) min vs. (151. 6±34. 7) min,t = -5. 101),the intraoperative blood loss ((273. 5±141. 6) ml vs. (371. 3±127. 2) ml,t = 7. 396),total bilirubin at seventh days after the operation (( 15. 7 ± 8. 9 ) μmol/ L vs. ( 26. 5 ± 10. 8 ) μmol/ L, t = 5. 320 ) and postoperative albumin supplementation((61. 0±9. 7) g vs. (84. 6±9. 3) g,t = 7. 698) of the observation group decreased. The tumor recurrence rate ( 0 vs. 8. 9% ( 4/ 45)), intrahepatic metastasis rate ( 7. 8% ( 4/ 51) vs. 20% ( 9/ 45)), extrahepatic metastasis rate (3. 9% (2/ 51) vs. 17. 8% (8/ 45)) (χ2 =. 031,6. 315,6. 746) decreased and the differences were statistically significant (P< 0. 05) . The 2 year and 3 year tumor free survival rate (88. 2%, 76. 5%) of the observation group was higher than those of the control group (64. 4%,44. 4%,χ2 = 5. 468, 8. 902),and the total survival rate of 3 year after operation (80. 4%) in the observation group was significantly, higher than that of the control group (51. 1%,χ2 = 4. 896),the difference was statistically significant (P<0. 05) . Conclusion Tissue-Link combined with Cusa is superior to Tissue-Link combined with Pringle in hepatectomy for primary hepatocellular carolnoma. It has less intraoperative blood loss, less damage to liver function and a lower relapse rate of ineisional margin,and the disease-free survival rate and overall survival rate are improved significantly.

Objective To investigate the influence of difference ileocecal junction length on the efficacy of laparoscopic subtotal colectomy combined with antiperistaltic cecorectal anastomosis (LSCACRA) in treatment of slow transit constipation (STC). Methods Ninety- two STC patients undergoing LSCACRA were divided into 2 groups by random digits table method:10-15 cm group (10-15 cm ascending colon preserved above ileocecal junction, 46 cases) and 2-3 cm group (2-3 cm ascending colon preserved above ileocecal junction ,46 cases). All the patients were followed up for 24 months, and the Wexner incontinence score (WIS), ileocecal junction emptying time of barium enema, Wexner constipation score (WCS), abdominal pain intensity score (NRS), gastrointestinal quality of life index (GIQLI), abdominal pain frequency score and abdominal bloating frequency score were compared between 2 groups. Results All the patients successfully completed LSCACRA, with no conversion to open surgery and death occurred. There were no statistical differences in amount of bleeding, operative time, hospitalization time, exhaust time, incidences of postoperative intestinal obstruction and pulmonary infection, defecation time, WIS and abdominal bloating frequency score between 2 groups (P>0.05). The WCS, GIQLI, NRS and abdominal pain frequency scores 6, 12 and 24 months after operation in 2-3 cm group were significantly better than those in 10 - 15 cm group, WCS: (1.7 ± 1.3) scores vs. (4.2 ± 2.3) scores, (1.7 ± 1.1) scores vs. (4.1 ± 1.9) scores, (1.2 ± 0.5) scores vs. (3.9 ± 2.5) scores;GIQLI:(116.8 ± 6.2) scores vs. (98.5 ± 14.7) scores, (122.9 ± 7.5) scores vs. (104.7 ± 16.5) scores, (124.3 ± 5.9) scores vs. (108.3 ± 15.1) scores; NRS: (1.3 ± 0.5) scores vs. (2.5 ± 1.7) scores, (0.9 ± 0.3) scores vs. (2.3 ± 1.4) scores, (0.8 ± 0.3) scores vs. (2.2 ± 1.5) scores;abdominal pain frequency score:(0.9 ± 0.3) scores vs. (1.6 ± 1.2) scores, (0.7 ± 0.3) scores vs. (1.4 ± 1.1) scores, (0.7 ± 0.2) scores vs. (1.2 ± 1.0) scores, and there were statistical differences (P<0.05). The ileocecal junction emptying time of barium enema 24 months after operation in 2-3 cm group was significantly shorter than that in 10-15 cm group: (17.6 ± 8.4) h vs. (21.3 ± 10.8) h, and there was statistical difference (P<0.05). Conclusions STC patients with LSCACRA is safe and effective. The shorter length of ascending colon preserved above ileocecal junction can improve the efficacy of LSCACRA in the treatment of STC and the prognosis of patients. The 2-3 cm length of ascending colon preserved above the ileocecal junction should be recommended.
