[Summary] Gastric cancer is seriously dangerous to human health with constantly high incidence .Human gastric mucosa can express gastrokines that can inhibit cancer cell growth .Gastrokines is expressed abundantly in normal tissues while downregulated or absent in gastric cancer and precancerous lesion .It plays an important role in the suppression of gastric cancer proliferation combining with the other factors such as helicobacter pylori infection or trefoil factors .In this paper we made a review about the suppression of gastrokines on gastric cancer cell proliferation .

Objective To evaluate the risk factors for prognosis in liver cirrhotic patients with acute esophageal variceal bleeding (EVB). Methods Retrospective analysis was carried out in patients with liver cirrhosis,who were admitted to the hospital for EVB between January 2000 and December 2006 . All patients were follow-up to August 31st, 2009. The death of the patients was identified as the end of the study. The vital signs and results of laboratory tests were recorded when patients were admitted to the hospital. Child-Pugh score/grade, model for end stage liver disease (MELD) score and Rockall score were calculated. Results Ninty-five cases (66 males and 29 females) were enrolled in the study. Among them, 60 cases died and 35 cases survived for (42. 61±33.21) months (ranged from 2 days to 114 months). Univariate Cox regression analysis showed that age, male, Child-Pugh score/grade, MELD score, Rockall score, white blood cell counts and active hepatitis B were risk factors for death in liver cirrhotic patients with EVB (P＜0.05), while high level of hemoglobin and high hematocrit, endoscopic variceal sclerosis therapy or surgical treatment were protective factors (P＜0.05). Multivariate Cox regression analysis revealed that Child-Pugh grade (RR= 4. 997,95%CI:2. 787～8. 960, P＜0.01),Rockall score (RR= 1. 284,95%CI:1. 062～1. 553,P=0. 010), high counts of white blood cells (RR= 1. 072,95%CI: 1. 001 ～ 1. 148, P= 0. 046) were risk factors for prognosis of liver cirrhotic patients with EVB. Conclusion It is demonstrated that Child-Pugh grade,Rockall score and high counts of white blood cells are risk factors for prognosis of liver cirrhotic patients with EVB.

Objective To investigate the clinical efficacy of fluoroscopy-guided intestinal adhesion lysis, as a new non-surgical method, in treating incomplete adhesive small intestinal obstruction in order to improve the therapeutic results of adhesive intestinal obstruction. Methods A total of 93 patients with incomplete adhesive small intestinal obstruction were enrolled in this study. The patients were divided into study group (n=49) and control group (n=44). Fluoroscopy-guided intestinal adhesion lysis together with restoration of inter-intestinal loop enterocele was carried out for the patients of the study group , while traditional conservative surgical therapy was employed for the patients of the control group. The study group was comparable with the control group in patients’ age, gender, medical history, disease course, X-ray findings, etc. Results Of the 49 cases in the study group, complete cure was obtained in 40 with a cure rate of 81.6%. The mean hospitalization day was 0.3 day, and the average operation time was 3.25 hours. Among the 44 patients in the control group, complete cure was obtained in 37 with a cure rate of 84.1%. The mean hospitalization day was 7.6 days, and the average therapeutic time was 183.26 hours. Conclusion For the treatment of incomplete adhesive small intestinal obstruction , the therapeutic efficacy of fluoroscopy-guided intestinal adhesion lysis together with restoration of inter-intestinal loop enterocele is better than that of traditional conservative surgical therapy.

Conclusion The morbidity of erosive reflux esophagitis rate is increasing parallel with the increase of age and severity of the lesion, and prevalence is more in males than females. The morbidity rate in males was higher than that in females. The incidence of e-rosive reflux esophagitis is not affected by H. pylori infection.

Objective: To investigate the effect of macrophage-capping protein (CapG) on migration and proliferation of human gastric cancer cell line.Methods: Real-time PCR method was used to detect the expression of CapG gene in four gastric cancer cell lines, and AGS cells with low expression and transfection were selected as the research objects.Specific primers were designed for CapG and recombinant plasmids synthesized.A lentivirus packaging system which could express CapG was constructed, and a cell line stably expressing CapG was established by infecting human gastric cancer cell line AGS cells.The effect of overexpression of CapG gene on the growth and proliferation of AGS cells was analyzed by CCK8 assay.Cells cratch and Transwell assay were used to analyze the effect of overexpression of CapG gene on AGS cell migration.Results: After the overexpression of CapG, the growth rate of AGS cells was slightly lower than that of the control group, but there was no significant difference between the two groups (t=2.424, P=0.073).Scratch test showed that the average narrowing distance of the scratches in the CapG experimental group was significantly reduced compared with the control group, the average narrowing distance of the CapG experimental group and the control group was 336.99 μm and 45.54 μm, the difference was statistically significant (t=14.97, P=0.004).The average number of cell penetra-ting membrane in the CapG experimental group and the eGFP control group was 176 and 70, the number of the cells in the CapG experimental group was significantly higher than that of the control group (t=40.00, P<0.001).Conclusion: The overexpression of CapG gene has no significant effect on the growth and proliferation of AGS cells of gastric cancer cell line.Overexpression of CapG gene can promote the migration of AGS cells of gastric cancer cell lines.

Objective To study the value of radiofrequency ablation of gallbladder beds in radical surgery for stage T1b gallbladder cancer.Methods A retrospective study was conducted on 21 patients with stage T1 b gallbladder cancer treated in the Department of Hepatobiliary Pancreas and Spleen Surgery,West Campus,Beijing Chaoyang Hospital,Capital Medical University,from April 1,2011 to March 31,2019.Patients who were diagnosed with frozen section during operation were included into the surgery group.Patients who were diagnosed postoperatively and underwent radical surgery for the gallbladder carcinoma were included in the secondary surgery group.The differences in surgical time,bleeding volume,survival rate,and survival time between the two groups after regular follow-up were compared,and the 5-year cumulative survival rates and overall survival time of the two groups were calculated.Results All patients underwent radical gallbladder cancer surgery.There were 14 males and 7 females,aged from 26 to 70 (49.0 ± 13.5)years.There were no perioperative deaths.There were 15 patients in the operation group,and 6 patients in the secondary surgery group.The bleeding volume of the surgery group was significantly less than the secondary surgery group [(101.3 ± 35.5) ml vs.(177.0 ± 44.6) ml,P ＜ 0.05].There were no significant differences in surgical time,survival rate,and survival time between the two groups (all P ＞ 0.05).The 5-year cumulative survival rate for the two groups of patients was 56.5％,and the overall survival time was (79.0 ± 9.3) months.Conclusions Radiofrequency ablation of the gallbladder bed was safe and effective in radical surgery of T1 b gallbladder cancer.For T1 b stage gallbladder cancer,which is difficult to diagnose during surgery,secondary radical surgery achieved the same results as primary radical surgery.

Objective:To analyze the effects of the primary location of colorectal cancer on the surgical outcome of liver metastases.Methods:A cross-sectional study was conducted on 178 patients with liver metastases from colorectal cancer admitted to Binzhou Central Hospital from January 2012 to January 2022. According to whether the patients had recurrence after surgery, they were divided into a recurrence group ( n = 88) and a control group ( n = 90). The general and clinical data were compared between the two groups. Logistic multivariate analysis of the factors with statistical significance was further performed to identify the risk factors of postoperative recurrence of liver metastases from colorectal cancer after surgery. The correlation between the primary location of colorectal cancer and each risk factor was analyzed. The recurrence of colorectal cancer was compared anong patients with different primary locations of colorectal cancer at 12 months after surgery. Results:Primary location at the right colon [55.68% (49/88), lymph node metastasis [92.05% (81/88)], D-dimer ≥ 180 μ g/L, albumin < 29 g/L, ineffective/no neoadjuvant chemotherapy [43.18% (33/38)], and high-risk clinical risk score [53.41% (47/88)] were risk factors for postoperative recurrence of liver metastases from colorectal cancer after surgery ( P = 0.024, 0.019, 0.001, 0.028, < 0.001, 0.001). The primary location of colorectal cancer was positively correlated with lymph node metastasis, D-dimer, and clinical risk score ( P = 0.043, 0.046, 0.030), and negatively correlated with albumin and the efficacy of neoadjuvant chemotherapy ( P = 0.004, 0.033). In 178 patients, the recurrence rate of liver metastases from colorectal cancer at 3 months [53.57% (15/70)], 6 months [55.17% (32/70)], and 12 months [55.68% (49/70)] was significantly higher in the right colon compared with the left colon [32.14% (9/40), 24.14% (14/40), 26.14% (23/40) and the rectum [14.29% (4/68), 20.69% (12/68), 18.18% (16/68)] ( χ2= 4.73, 7.85, 6.27, all P < 0.05). Conclusion:Right colon, lymph node metastasis, D-dimer, albumin, neoadjuvant chemotherapy efficacy, and clinical risk score are the risk factors for postoperative recurrence of liver metastases from colorectal cancer. Patients with the primary location at the right colon have a higher postoperative recurrence rate.
