Objective To study the expression of BRG1 gene in colon cancer and its relationship with histological grade and clinicopathological stages characteristics.Methods The expression of BRG1 -positive cancer cells were detected by immunohistochemistry in 100 cases of colon cancer,and the relationship with histological grade and clinicopathological stages characteristics was analyzed.Results Of the 100 colon cancer specimens analyzed,the positive expression rate was 82.0%.The expression of BRG1 in colon cancer tissue with histological grade and TNM staging was significantly different (χ2 =23.509,P =0.024;χ2 =25.659,P =0.002).The higher the histological grade,the stronger the BRG1 expression in colon cancer tissue.BRG1 expression in advanced colon cancer tissue was significantly enhanced in the early stage.Conclusion The appearance of BRG1 -positive cancer cells is associated with histological grade and clinicopathological stages characteristics.BRG1 might play an important role in the development of colon cancer.

Objective To analyze the clinical efficacy of endovenous laser treatment combined with transilluminated powered phlebectomy for great saphenous varicosity and summarize the experiencein order to achieve better results.Methods From January 2014 to June 2015,45 patients (52 limbs,including 17 males and 28 females,aged 36 to 68 years) diagnosed as great saphenous varicosity received endovenous laser treatment combined with transilluminated powered phlebectomy.Thirty-eight cases was unilateral great saphenous vafcose veins,7 cases was bilateral large saphenous varicose veins.The clinical efficacy was analyzed.Results All cases were performed successfully.The mean operation time was (68.4 ± 15.1) minutes,the average bleeding volume was (23.5 ± 10.7) ml,the number of mean operative incision quantity was (5.8 ± 1.9) and the average hospitalization time was (5.9 ± 1.6) days.All patients had no serious complications.During a mean follow-up time of 22 months (12 to 30 months),only one patient recurred.Conclusions Endovenous laser treatment combined with transilluminated powered phlebectomy for great saphenous varicosity is effective and safe.It also has the advantages of shorter operation time,less bleeding,shorter hospitalization time,small trauma and better cosmetic results.

Objective To compare the efficacy of endovenous laser treatment combined with transilluminated powered phlebectomy and traditional surgical treatment for great saphenous varicosity. Methods From January 2014 to January 2015,77 patients diagnosed as great saphenous varicosity were enrolled. They were randomly divided into two groups, 37 patients received endovenous laser treatment combined with transilluminated powered phlebectomy and the other 40 patients underwent traditional surgical treatment. The related indicators were compared.Results The mean operation time,average bleeding volume,operative incisionquantity and average hospitalization time of EVLT+ TIPP group were (66.1±14.7) min,(24.4±10.5) ml,5.7±1.7,(5.6±1.4) d respectively,of control group were (84.3±18.5) min,(59.0±15.6) ml,8.0±1.8,(10.1±3.1) d respectively,there were significant differences between the two groups(t =-4.749,-11.460,-5.714;P<0.001) .There were no significant complications in the two groups.In the EVLT+ TIPP group,6 patientsoccurred patsubcutaneous induration, 5 patients occurred subcutaneous hematoma and 7 patients had skinparesthesias.In the traditional operation group,2 cases occurred patsubcutaneous induration,3 cases occurredsubcutaneous hematoma and 2 cases had skin paresthesias.The EVLT+ TIPP group was slightly higher than thetraditional operation group in the complications, but there were no significant differences between them ( P>0.05).During a mean follow?up time of (18±7) months(12 months to 24 months),1 patient recurrence in theEVLT+ TIPP group,2 cases recurrence in the traditional operation group.The recurrence rates of the two groupswere similar,the difference was not significant between them(P=1.000) .Conclusion Endovenous lasertreatment combined with transilluminated powered phlebectomy for great saphenous varicosity is effective andsafe.It also has the advanta and better cosmetic results.

Objective:This study focuses on Na +-taurocholate cotransporting polypeptide (NTCP) deficiency to analyze and investigate the value of the serum bile acid profile for facilitating the diagnosis and differential diagnosis. Methods:Clinical data of 66 patients with cholestatic liver diseases (CLDs) diagnosed and treated in the Department of Pediatrics of the First Affiliated Hospital of Jinan University from early April 2015 to the end of December 2021 were collected, including 32 cases of NTCP deficiency (16 adults and 16 children), 16 cases of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD), 8 cases of Alagille syndrome, and 10 cases of biliary atresia. At the same time, adult and pediatric healthy control groups (15 cases each) were established. The serum bile acid components of the study subjects were qualitatively and quantitatively analyzed by ultra-high performance liquid chromatography-tandem mass spectrometry. The data were plotted and compared using statistical SPSS 19.0 and GraphPad Prism 5.0 software. The clinical and bile acid profiles of children with NTCP deficiency and corresponding healthy controls, as well as differences between NTCP deficiency and other CLDs, were compared using statistical methods such as t-tests, Wilcoxon rank sum tests, and Kruskal-Wallis H tests.Results:Compared with the healthy control, the levels of total conjugated bile acids, total primary bile acids, total secondary bile acids, glycocholic acid, taurocholic acid, and glycochenodeoxycholic acid were increased in NTCP deficiency patients ( P < 0.05). Compared with adults with NTCP deficiency, the levels of total conjugated bile acids and total primary bile acids were significantly increased in children with NTCP deficiency ( P < 0.05). The serum levels of taurochenodeoxycholic acid, glycolithocholate, taurohyocholate, and tauro-α-muricholic acid were significantly increased in children with NTCP deficiency, but the bile acid levels such as glycodeoxycholic acid, glycolithocholate, and lithocholic acid were decreased ( P < 0.05). The serum levels of secondary bile acids such as lithocholic acid, deoxycholic acid, and hyodeoxycholic acid were significantly higher in children with NTCP deficiency than those in other CLD groups such as NICCD, Alagille syndrome, and biliary atresia ( P < 0.05). Total primary bile acids/total secondary bile acids, total conjugated bile acids/total unconjugated bile acids, taurocholic acid, serum taurodeoxycholic acid, and glycodeoxycholic acid effectively distinguished children with NTCP deficiency from other non-NTCP deficiency CLDs. Conclusion:This study confirms that serum bile acid profile analysis has an important reference value for facilitating the diagnosis and differential diagnosis of NTCP deficiency. Furthermore, it deepens the scientific understanding of the changing characteristics of serum bile acid profiles in patients with CLDs such as NTCP deficiency, provides a metabolomic basis for in-depth understanding of its pathogenesis, and provides clues and ideas for subsequent in-depth research.

Objective To study the changes of blood coagulation function in early stage of acute renal failure patients, and illustrate its significance. Methods From October 2011 through January 2013, 80 patients with acute renal failure in the Nephrology Department and Pediatrics Department of Yuebei People’s Hospital were enrolled in this study,50 health people in the same period as control group,then compare the differences in creatinine, blood urea nitrogen, blood platelet(PLT), activated partial thromboplastin time(APTT), prothrombin time(PT), thrombin time(TT), plas-ma fibrinogen (FIB) between the two groups. Results The FIB levels and PLT count in observation group were higher than those of controls group (P<0.05), but APTT,PT,TT showed no statistically significant difference (P>0.05). Con-clusion Hypercoagulabale state could occur in patients with acute renal failure in early stage, abnormal clotting may be participates in occurrence of acute renal failure.
