Objective To evaluate the efficacy of transcatheter arterial chemoembolization(TACE) combined with radiofrequency ablation(RFA) in treating primary hepatocellular carcinoma(HCC).Methods From March 2004 to March 2006,137 patients with primary HCC underwent TACE alone(n=87) and TACE+RFA(n=50),respectively,after the interventional treatment,all patients periodically received CT reexaminations and alpha fetoprotein(AFP) measurement.The therapeutic efficacy,AFP level and survival rate between two groups were compared with each other.Results In TACE group the effective rate(CR+PR) was 34.5%,AFP decreasing amplitude was 54.2%,and 2 years survival rate was 43.7%.While in TACE+RFA group,the effective rate(CR+PR) was 70.0%,AFP decreasing amplitude was 78.0%,and 2 years survival rate was 62.0%,there were significant differences between two groups(P

Objective To investigate the clinical significance of changes of serum insulin-like growth factor-Ⅱ(IGF-Ⅱ),carbohydrate antigen 19-9(CA19-9)and alpha fetoprotein(AFP)levels after intervention and percutaneous ethanol injection therapy in patients with primary hepatic cancer.Methods Serum levels of IGF-Ⅱ,CA19-9 and AFP(with RIA)were repeatedly determined in 57 patients with primary hepatic cancer before intervention therapy,1 month after intervention and percutaneous ethanol injection therapy and 6 months after intervention and percutaneous ethanol injection therapy as well as in 42 controls.Results Before intervention therapy,serum leveh of IGF-Ⅱ,CA19-9 and AFP in the patients were significantly higher than those in the controls(P＜0.01).One month after intervention and percutaneous ethanol injection therapy,all the serum levels were near to normal.Six months later,the levels in the patients without recurrence remained normal.However,the levels in the 10 patients with recurrence returned to those before intervention therapy again.Conclusion Changes of serum IGF-Ⅱ,CA19-9 and AFP levels are closely related to the tumor burden and may reflect the presence of recurrence.

Objective To explore the relationship between responsibility and social adaptation of the left-behind middle school students and to provide evidence for mental health education of left-behind children.Methods 290 left-behind middle school students were selected by cluster-random-sampling.All of them were assessed by the middle school students' social adaptability scale (SAS-SSS),the inventory of parent and peer attachment (IPPA) and the scale of high school students' responsibility.Results The correlation between responsibility,attachment behavior and social adaptation of left-behind middle school students were significant(r=0.39,r=0.56,P＜0.01).There were significant differences between gender on the responsibility(male(202.64±26.78) vs female(212.67±23.24)).Regression analysis showed that mother attachment,overall responsibility,general responsibility and special fault responsibility could predict the social adaptation(P＜0.05).Responsibility and its factors played a mediating role between attachment and adaptation,taking 52.1％,20.1％,30.8％,9.1％,47.9％,40.7％ proportion of the total effect.Conclusion Responsibility is an important factor affecting the social adaptation of left-behind middle school students.

Objective To investigate whether Senxing granule is effective on deferring aging and its mechanism. Methods The assay methods for life span of fruit fly and rat antioxidation were used for the study. Level of lipoperoxide, activity of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in whole blood and liver tissue was measured. Low dose of Senxing granules in the culture medium was decided as 0.007 % and middle dose as 0.022 %. Results Low dose of Senxing granule significantly increased the mean life span of female fly by 3.7%( P

Objectives To analyze the expression of fibroblast growth factor-19(FGF-19) in hepatocellular carcinoma ( HCC) and adjacent tissues , and to investigate its clinical significance .Methods A total of 209 HCC patients who had undergone radical resection operations at Hospital 401 between January 2003 and December 2009 were chosen as samples . Immunohistochemistry method was employed to examine the expression level of FGF-19 in HCC and adjacent tissues .The relationship between FGF-19 protein expressions and clinicopathological features was analyzed by the chi -square test or Fisher exact probability .A survival curve was drawn using the Kaplan-Meier method and the Cox model was used to analyze factors that influenced survival .Results The rate of high expression of FGF-19 was 66.1% (138/209) in HCC, which was significantly higher than 46.9%(98/209) in adjacent tissues (P<0.05).The high expression of FGF-19 was related to the tumor capsule and tumor boundary (P<0.05).The overall survival in high expression of FGF-19 group was signifi-cantly lower than that in low expression group (P<0.05).Conclusion FGF-19 plays an important role in the carcinogen-esis and development of HCC , and a high expression of FGF-19 might be closely related to survival time of postoperative patients.FGF-19 might be a potential prognosis prediction factor for HCC .

Objective The application of nano-carbon tracer technique in radical antegrade modular pancreatosplenectomy (RAMPS) to treat malignant tumors of pancreatic body and tail.To investigate whether radical anterograde modulization of pancreatic body and tail combined with nano-carbon tracer technique is more beneficial to the prognosis of patients.Methods From January 2014 to September 2018,a retrospective analysis was performed in 48 patients in Linyi Central Hospital,all patients underwent RAMPS,all of whom were pathologically proved to be pancreatic carcinoma of the body and tail.Based on whether the nano-carbon lymph node tracer was performed during the operation,the patients were divided into two groups:nano-carbon group (nano-carbon lymph node tracing) and conventional operation group (no nano-carbon lymph node tracer).The differences between the two groups were analyzed,including operative time,intraoperative blood loss,postoperative complications (pancreatic fistula),postoperative hospitalization time,postoperative pathological lymph node status (number of dissection,number of positive lymph nodes,the positive rate of lymph node black staining in nano-carbon group) and survival time after operation.The measurement data were expressed as mean ± standard deviation (Mean ± SD),t-test were used for comparison among groups;Chi-square test was used for comparison of counting data,and Kaplan-Meier test was used for comparison of survival rate.Results There was no significant difference in the time of operation [(4.45 ± 0.59) h vs (4.41 ±0.65) h],the amount of blood lost during operation [(447.39 ± 109.51) ml vs (434.8 ± 76.38) ml] and the time of hospitalization after operation [(16.52 ± 4.12) d vs (16.56 ±2.92) d] between the two groups (P＞0.05).There were 1 case of pancreatic fistula in the nano-carbon group and 2 cases of pancreatic fistula in the convertional operation group,but the difference was not statistically significant (P =0.55).The number of lymph nodes dissected and positive lymph nodes in nano-carbon group were significantly higher than those in conventional operation group [(18.26 ± 2.49) vs (12.16 ± 2.19);(5.52 ± 1.50) vs (3.32 ± 0.85).The difference was statistically significant (P ＜ 0.05).The positive rate of lymph nodes in black stained lymph nodes (38.10％,96/252) was significantly higher than that in non-stained lymph nodes (18.45％,31/168),and the difference was statistically significant (P ＜ 0.05).The average survival time in the nano-carbon group [(25.48 ± 11.74) months] was significantly longer than that in the conventional operation group [(15.80 ± 11.64) months],and the difference was statistically significant (P ＜ 0.05).Conclusions It is safe,effective and feasible to treat malignant tumors of pancreatic body and tail by RAMPS combined with nano-carbon tracer technique.The positive rate of lymph node dissection and the detection rate of total lymph nodes are increased,and the prognosis of patients is improved,to improve the survival time of patients after operation is improved.

ObjectiveTo investigate the three-year follow-up outcomes of hepatocellular carcinoma patients undergoing liver resection (LR) versus liver transplantation (LT). MethodsA retrospective analysis was performed for 171 patients with hepatocellular carcinoma who underwent surgical treatment in Beijing YouAn Hospital, Capital Medical University, from March 2009 to March 2014, and according to the treatment method, they were divided into LR group(n=83) and LT group(n=88). Related clinical data were compared between the two groups. The chi-square test was used for comparison of categorical data between two groups; the Kaplan-Meier survival curve and the log-rank test were used for comparison of disease-free survival and overall survival between two groups, and the Cox proportional hazards model was used for the univariate and multivariate analyses of disease-free survival and overall survival. ResultsCompared with the LR group, the LT group had a significantly higher proportion of patients with single tumor ［45.78% (38/83) vs 85.23% (75/88), χ2=29649,P＜0.001］, tumor size ＜3 cm ［15.66% (13/83) vs 6705% (59/88), χ2=46.383,P＜0001］, or high Child-Pugh class ［ 964% (8/83) vs 26.14% (23/88),χ2=7833,P=0.005］ and a significantly lower recurrence rate of tumor ［48.19%(40/83) vs 3295%(29/88) ,χ2=4121,P=0.042］. There was a significant difference in disease-free survival rate between the LR group and the LT group (46.02% vs 80.71%, P=0.006); the LT group had a higher overall survival rate than the LR group (86.99% vs 76.44%, P=0.219). Both univariate and multivariate analyses showed that treatment method was an independent risk factor for disease-free survival (risk ratio［RR］=3383,95% confidence interval［CI］: 1334-8579;RR=0239,95%CI:0093-0.612，both P＜005), but the prediction of overall survival by treatment method did not reach statistical significance(P=0232). ConclusionLT is recommended for patients with early-stage hepatocellular carcinoma and can achieve a satisfactory three-year disease-free survival rate.
