Fascin is an actin-bundling protein that is normally expressed in mesenchymal tissue and the nervous system. Many recent studies have shown that fascin was highly expressed in many human tumors and played a significant role in tumor proliferation, invasion, and metastasis. Fascin expression is also an independent factor correlated with poor patient prognosis and decreased survival rate. Fascin can be explored as a new molecular target for cancer treatment,thus can improve tumor patients' prognosis.

Objective To evaluate the international blood smear review criteria for improvement using Beckman-Coulter hematology analyzers and find out proper slide review criteria suitable for Chinese population. Methods 3 600 random-selected blood samples were tested in three hospitals using MAXM, GENS and LH750 5-diff automated analyzers and a manual differential with a smear review was performed on all samples in the study. True positive rate, true negative rate, false positive rate and false negative rate were calculated according to the international blood smear review criteria. We have set up smear review criteria for Chinese population by analyzing false positive and false negative cases according to Chinese clinical conditions. Another 240 blood samples were tested in three hospitals using the same analyzers to verify the new slide review rules. Results According to international blood smear criteria, the true positive rate was 4.9%, false positive rate was 24.2%, true negative rate was 70.4% and false negative rate was 0.5%. The international smear review criteria were modified into 23 criteria by analysis of above statistical data. In addition, we added four WBC differential ratio rules in positive smear criteria. After modification, the true positive rate was 9.9% (355/3 600) ,false positive rate was 17.1% (617/3 600), true negative rate was 71.2 % (2 563/3 600) and false negative rate was 1.8% (65/3 600). No blast cell was missed using both smear review criteria. A little higher false negative rate after modification was caused by supplemented differential ratio roles in positive smear criteria. Verification results were satisfactory;The tree positive rate was 13.7% (33/240) ;false positive rate was 15.8% (38/240) ;false negative rate was 2.5% (6/240) and true negative rate was 68.0% (163/240). Conclusions Although the smear review criteria suggested by the International Consensus Group is clinically important, the false positive rate increases when they are used in Chinese population. The modified slide review criteria used on Beckman-Coulter hematology analyzers in this study are more suitable for Chinese laboratories.

IL-17 is one of more than 30 kinds of interleukin, which plays an important role in many biological processes. Under normal circumstances, IL-17 can cause inflammation. However, under pathological conditions, IL-17 can also promote a variety of tumors. Hepatocellular carcinoma (HCC) is the most common type of liver cancer.It has rapid development, poor prognosis, easy metastasis, and obvious inflammatory reaction in tumor microenvironment. These biological characteristics suggest that the occurrence and development of HCC are related to the expression of IL-17. IL-17 can affect the growth, development and autophagy of hepatocellular carcinoma through a variety of ways. For example, promot the growth of hepatocellular carcinoma through the AKT/IL-6/JAK2/STAT3 signaling pathway and the miR-383/STAT3 axis, increase the expression of MMPs by activating the NF-κB signaling pathway to promote hepatocellular carcinoma metastasis, enhance the expression of PIAS1 through the NF-κB pathway to inhibit the anti-tumor effect of IFN-γ, and by inhibiting the degradation of Bcl2 in Bcl2-Beclin1 to inhibit autophagy of hepatocellular carcinoma cells. This article reviews the research status of IL-17 in the pathogenesis of hepatocellular carcinoma.

Objective To summarize the experience in nursing patients with gut leak after liver transplantation. Methods Two patients with recurrent gut leakafter liver transplantation underwent surgical repair. The nursing measures included strict observation of postoperative disease, observation of drainage fluid and abdominal signs, early nutritional support, good psychological nursing and health education. Results Gut leak occurred in the two cases again after liver transplantation.One case was treated with repair again and the other with end-stage ileotomy and ileostomy. The patients were discharged after medication and nursing care. Conclusions The close postoperative observation of the disease, observation of drainage fluid and abdominal signs can prompt the discovery of intestinal re-perforation.The early nutritional support plays an important role in the rehabilitation of patients with gut leak after liver transplantation.Mental care and health education can enhance patient's confidence in treatment.

Objective: To explore the related factors for primary hepatic carcinoma (PHC) caused by chronic hepatitis B (CHB) and hepatitis C (CHC). Methods: According to the principle of cross-sectional study, a cluster random sample method was used, a total of 366 chronic hepatitis patients in hospitals were recruited from three provincial tertiary hospitals in Shanxi, Henan and Jilin between July 2016 and October 2016, respectively. Using a self-designed unified questionnaire, face-to-face interviews was conducted on subjects, including sex, age, alcohol consumption, coffee consumption, green tea consumption, fish consumption, smoking, HBV/HCV diagnosis and treatment, diabetes mellitus, family history of PHC (whether PHC in first-degree relatives), etc. Multivariate unconditional logistic regression were performed to identify the related factors for PHC with CHB and CHC. According to the clinical diagnosis the patients were divided into a chronic hepatitis group (not developing to PHC) and a PHC group. Results: Among 366 cases patients, 287 (78.4%) cases were male, 79 cases were female (21.6%), average age was (52.7±9.3) years. 202 cases were chronic hepatitis group, 164 cases were PHC group. Multivariate unconditional logistics regression analysis indicated that alcohol consumption (odds ratio (OR)=2.11, 95%CI: 1.18-3.75), family history of PHC (OR=5.12, 95%CI: 2.60-10.08) were positively correlated with the development of PHC in chronic b, green tea consumption (OR=0.45, 95%CI: 0.23-0.88), antiviral treatment (OR=0.19, 95%CI: 0.11-0.32) were negatively correlated. Alcohol consumption (OR=3.98, 95%CI: 1.14-13.85) was positively correlated with the development of PHC in chronic c, antiviral treatment (OR=0.14, 95%CI: 0.04-0.50) was negatively correlated. Conclusion Alcohol consumption, family history of PHC, green tea consumption and antiviral treatment were the related factors for the development of PHC in chronic hepatitis b. Alcohol consumption and antiviral treatment were the related factors for the development of PHC in chronic hepatitis c.

BACKGROUNDSerine threonine kinase 15 (STK15) is a kind of mitotic kinase. The overexpression of STK15 is significantly associated with carcinogenesis in many tumors, however, its expression and significance in human lung cancer are still unclear. The aim of this study is to investigate the expression of STK15 in squamous cell carcinoma and adenocarcinoma of the lung and to analyze the correlation between STK15 expression and clinicopathological factors.

METHODSThe pattern of STK15 protein expression was detected in 44 squamous cell carcinomas, 36 adenocarcinomas and 20 paracancerous lung tissue samples by immunohistochemistry method using anti-STK15 antibody. The relative quantity of STK15 protein expression was detected by Western blot, and STK15 mRNA expression was detected by RT-PCR in 40 fresh lung cancer samples and corresponding paracancerous lung tissues.

RESULTSPositive expression rate of STK15 protein was 68.75% (55/80) in lung cancer tissues and 0% in paracancerous controls (P < 0.001). STK15 expression was significantly related to differentiation grade of lung cancer (P=0.011), but not to histological classification, TNM stages or lymphatic metastasis (P > 0.05). The relative expression levels of STK15 protein (P < 0.001 ) and STK15 mRNA (P < 0.001) in lung cancer tissues were both significantly higher than those of corresponding paracancerous lung tissues.

CONCLUSIONSThe expression of STK15 protein and STK15 mRNA is significantly higher in lung cancer tissues than that in paracancerous lung tissues. The expression of STK15 correlates with differentiation of lung cancer.

Objective: To investigate the effect of transcatheter arterial chemoembolization(TACE) combined with three dimensional conformal radiotherapy(3-DCRT) and hyperthermia on inoperable primary hepatic carcinoma. Methods: This study retrospectively analyzed 96 patients with hepatic carcinoma in the Third Hospital of Chengde between 2014 and 2017 who received TACE or combined therapy (TACE combined with 3-DCRT and hyperthermia). Kaplan-Meier curve was used to compare the overall survival(OS) of the two groups. Results: There were 50 cases in the combined therapy group, 46 cases in the TACE group.The effective rate of the combined therapy group was 76.1%, and that of TACE group was 45.6%, the difference was statistically significant(P=0.028). The overall 6-, 12- and 18-month survival rates of the combined therapy group were 98.0%, 89.9% and 63.1%, respectively, which in the TACE group were 91.3%, 67.3% and 46.8%, respectively, the difference between the two groups was significant(χ²=7.836, P=0.005). The incidence of adverse effect of the combined therapy group was low, only 2 patients(4.0%) developed radiation-induced liver disease(RILD), and the liver function recovered to the normal level after 8 weeks. Conclusion TACE combined with 3-DCRT and hyperthermia is more effective than TACE alone for inoperable primary hepatic carcinoma, and with a low incidence of adverse effect.
