Hepatic resection is considered curative treatment for patients with hepatocellular carcinoma (HCC),but the range of indication is narrow. Liver transplantation(LT) is another option, but recurrence and metastasis reduce long-term and medium-term survival. Appropriate patient selection is crucial in ensuring acceptable outcomes. Novel anticancer agents (chemotherapy and molecular target therapy) and appropriate use of immunosuppressant hold promise for improving the outcomes.

Objective To evaluate the clinical application value of local injections of carbon nanoparticle in gastrectomy of stomach neoplasms.Methods Forty cases of stomach neoplasms with local injections of carbon nanoparticle in gastrectomy of stomach neoplasms were as experimental group,and 40 cases of stomach neoplasms with conventional gastrectomy of stomach neoplasms were as control group.The number of removed tiny lymph node and transferred tiny lymph node was compared.Results There was significant difference in the average number of removed tiny lymph node N1,N2,N3 between experimental group and control group (5.120 ± 0.455 vs.2.900 ± 0.245,3.890 ± 0.367 vs.1.750 ± 0.256,1.790 ± 0.224 vs.0.590 ± 0.054)(P ＜ 0.01).There was significant difference in the average number of transferred tiny lymph node N1,N2,N3 between experimental group and control group (1.090 ±0.087 vs.0.430 ± 0.044,0.550 ± 0.052 vs.0.340 ± 0.027,0.410 ± 0.044 vs.0.130 ± 0.013)(P ＜ 0.05).There was no significant difference in postoperative complications,mortality and length of hospital stay(P＞ 0.05).Conclusion Carbon nanoparticle in gastrectomy of stomach neoplasms is a simple,safe,easy method,and it has certain supplementary role in conventional gastrectomy of stomach neoplasms.

Objective To investigate the causes and prevention of postoperative pain of laparoscopic transabdominal preperitoneal (TAPP) and Lichtensteinrepair in the treatment of adult recurrent inguinal hernia.Methods Sixty adult recurrent inguinal hernia patients were enrolled in this study.They were divided into TAPP group and Lichtenstein group by random digits table,with 30 cases in each group.At 6 h Mter operation,the pain degree was evaluated by visual analogue scale (VAS) and compared between two groups.The level of VAS in TAPP group was (3.76 ± 1.47) scores,in Lichtenstein group was (6.36 ± 1.54) scores,and there was significant difference (t =-5.978,P =0.000).In TAPP group,pain was mainly moderate (17 cases,56.67％) and mild (11 cases,36.67％).In Lichtenstein group,pain was mainly moderate (14 cases,46.66％) and severe (13 cases,43.33％).Postoperative follow-up ranged from 6 to 48 months.No chronic pain appeared in TAPP group.There were 4 cases with chronic pain in Lichtenstein group,and the incidence rate of chronic pain was 13.3％.Conclusions The operation of TAPP in the treatment of recurrent inguinal hernia in adult patients has the advantage of shorter operation time,less postoperative pain,faster postoperative recovery,and can effectively reduce the incidence of postoperative pain.

Objective To compare the clinical efficacy of laparoscopic repair of laparoscopic transabdominal preperitoneal(TAPP)and Lichtenstein tension-free repair herniorrhaphy in the treatment of recurrent inguinal hernia in adults,and to explore the clinical advantages of TAPP in the treatment of recurrent inguinal hernia.Methods A retrospective analysis was conducted in 54 adult patients with recurrent inguinal hernia from December 2010 to January 2015.The patients were randomly divided into TAPP group and Lichtenstein group.The operation time,intraoperative bleeding volume,postoperative hospitalization time,cost of hospitalization,postoperative complications,early postoperative pain and the recurrence of hernia were compared between the two groups.Results All patients were successfully completed surgery.The operation time of TAPP group (47.2 ±9.4)min was significantly shorter than (73.1 ±10.4)min of Lichtenstein group (t=-2.503,P=0.034).The median amount of bleeding during operation of TAPP group was 40(15 -110)ml,which was significantly less than 73(11 -130)ml in Lichtenstein group (t=-6.018,P=0.000). Postoperative hospital stay of TAPP group[(6.5 ±1.4)d]was shorter than (8.2 ±1.6)d of the Lichtenstein group (t=-2.613,P=0.028).Early postoperative pain score of TAPP group[(1.8 ±1.2)points]was better than (2.9 ± 1.4)points in Lichtenstein group (t=-7.006,P=0.000),the difference was statistically significant.However,the hospitalization cost of TAPP group[(8 842.8 ±415.2)yuan]was higher than (6 676.9 ±327.6)yuan of the Lichtenstein group,the difference was statistically significant(t=6.782,P<0.05).In TAPP group,2 cases had complications after operation,which were less than 5 cases of Lichtenstein group.Postoperative follow up ranged from 6 to 48 months,1 case of recurrence in Lichtenstein group,the recurrence rate was 3.8%.There was no recurrence in the TAPP group.Conclusion TAPP has the advantages of short operation time,less bleeding,rapid postoperative recovery,less postoperative pain and so on.It can be used as a recommended procedure for the treatment of recurrent inguinal hernia in adults.

Objective To evaluate the clinical application value of active carbon nanoparticles to guide breast cancer tiny lymphadenectomy.Methods 50 patients with breast cancer were enrolled in the study and were divided into two groups by random number table.Active carbon particle was injected locally to guide the regional lymph nodes dissection in 25 cases as study group,and the traditional method was performed in 25 cases as observation group.Numbers of dissected lymph nodes were compared between two groups.Results The average number of eliminated small lymph nodes in the study group was dramatically more than that in the observation group[(23.60 ±4.61)vs. (14.60 ±5.16),t =3.47,P <0.05].There was significant difference between the study group and the observation group in the small ambulant lymph nodes[(5.80 ±1.49)vs.(2.89 ±1.66),t =2.91,P <0.05)].Conclusion Active carbon injected locally can eliminate not only more small lymph nodes,but also more small ambulant lymph nodes.
