AIM： To investigate the tumorigenicity of lung cancer by learning the accumulation of p53 and the exposure of cytokeratin 18 neo-epitope(CK-18neo) related to the clinicopathological parameters in non-small cell lung cancer(NSCLC). METHODS: To detect the monoclonal antibodies of p53 and M30 CytoDEATH(specific antibody for CK-18neo) in 62 cases of NSCLC (included 29 cases of squamous cell carcinoma and 33 cases of adenocarcinoma) and 10 cases of control group by adopting immunohistochemistry assay (LSAB). Moreover, the immunoreactivity of p53 was quantitatively evaluated with positive unit (PU). RESULTS: (1) p53 immunoreactivity was positive in 15 of 29 squamous cell carcinoma (51.72%), 15 of 33 adenocarcinoma (45.45%), 30 of 62 NSCLC (48.39%). In 10 control cases was negative. There were significant differences between these groups (P＜0.01). (2)In 62 cases of NSCLC, AI% of M30 is 1.10%, and in 29 cases of squamous cell carcinoma is 0.95%, and in 33 cases of adenocarcinoma is 1.24%. In 10 control cases, the AI% is 1.06%. There is not significant difference among these groups . (3) According to the results of Pearson's correlation analysis, we found positive linear correlation between the immunoreactivity of p53（-/+）, p53（5 degrees）and p53（PU）(P＜0.01). CONCLUSION: Our results suggested that the pathogenesis of NSCLC might be related to the mutation of gene p53 and cell excessive proliferation and insufficient apoptosis.

Objective To sum up effective measures to prevent complications of peripherally inserted central catheter (PICC) by applying evidence-based nursing in patients after PICC insertion.Methods From January 2011 to January 2013,1490 patients inserted with PICC in Hunan Provincial Tumor Hospital were selected by convenience sampling,whom were divided into control group (n =758) and observation group (n =732) with random number table.The control group received routine care,while the observation group received evidence-based nursing.Nursing program for the observation group was formed based on literature regarding the causes of and solutions for phlebitis,malposition of PICC,infection of insertion sites,and hemorrhage of insertion sites.Results The incidences of postoperative phlebitis,malposition of PICC,infection of insertion sites,and hemorrhage at insertion sites in the observation group were significantly lower than those in the control group (3.14％ vs.8.97％,P=0.023;4.23％ vs.11.74％,P=0.021;3.96％ vs.8.44％,P=0.001;4.92％vs.12.66％,P =0.011).Conclusions The application of evidence-based nursing in patients with PICC insertion could effectively reduce the complication,and improve the quality of clinical nursing care.

Objective To investigate the correlated factors of pulmonary metastasis of hepatocellular carcinoma (HCC),so as to provide theoretical evidences for the prevention and treatment.Methods The clinical data of 862 patients with HCC who were admitted to the First Affiliated Hospital of Fujian Medical University from January 2008 to March 2012 were retrospectively analyzed.There were 107 patients with pulmonary metastasis.Factors including serum alpha fetoprotein (AFP) level,serum gamma-glutamyl transpeptidase (GGT) level,hepatitis B virus (HBV) infection,presence and treatment of intrahepatic tumor were analyzed to screen out relevant factors of pulmonary infection of HCC.Univariate and multivariate COX regression model analysis were performed for data analysis.Results The results of univariate analysis showed that high level of AFP (≥400 μg/L),ultra-high level of GGT (≥ 150 U/L),presence of HBV infection,the number of intrahepatic tumors ≥2,no radical resection (or radiofrequency ablation) for intrahepatic tumors,combining with tumor thrombi in the vessels,lymph node metastasis were risk factors of pulmonary metastasis of HCC (RR =1.986,3.653,0.365,3.675,0.252,0.379,0.352,P ＜ 0.05).The results of multivariate analysis showed that high level of AFP (≥400 μg/L),HBV infection,the number of intrahepatic tumors ≥2,no radical resection (or radiofrequency ablation) for intrahepatic tumors,combining with tumor thrombi in the vessels were risk factors of pulmonary metastasis of HCC (RR =2.391,3.462,3.425,3.396,2.418,0.638,P ＜ 0.05).Conclusions AFP ≥400 μg/L,HBV infection,the number of intrahepatic tumors ≥ 2,no radical resection (or radiofrequency ablation),tumor thrombi in the vessels and lymph node metastasis are risk factors of pulmonary metastasis of HCC.Anti-hepatitis virus treatment and early treatment are helpful for the prevention and treatment.

Objective To investigate the clinical efficacy of laparoscopic hepatectomy.Methods The clinical data of 258 patients who received laparoscopic hepatectomy at the First Affiliated Hospital of Fujian Medical University from March 2010 to January 2013 were retrospectively analyzed.There were 196 patients with primary hepatic cancer,45 with hepatic hemangioma,13 with hepatic focal nodular hyperplasia,2 with hepatic metastatic cancer,1 with carcinoma of gallbladder and 1 with hepatic hamartoma.All patients were followed up via phone call or out-patient examination till March 2013.Results A total of 142 patients received single hepatic segmentectomy,98 received multiple hepatic segmentectomy,18 received multiple lesions resection.Fifty-one patients received hepatic tumorectomy + cholecystectomy.All the operations were successfully done under laparoscope without conversion to the open surgery.The mean tumor diameter and the operation time were (5 ± 3) cm (range,1.0-11.5 cm) and (113 ± 56) minutes (range,50-310 minutes),respectively.Intraoperative hepatic portal occlusion was performed on 122 patients,and the time for hepatic portal occlusion was (15 ± 7)minutes.The volume of intraoperative blood loss was (211 ± 195)mL (range,10-650 mL),and blood transfusion was not needed.The capsule of the tumor was complete.The distance between the resection margin and the malignant tumor was above 1.5 cm,and there was no residual tumor in the resection margin.The hepatic function was back to the normal level in 1 week after the operation,and no patient had hepatic failure.The duration of postoperative hospital stay was (7.2 ± 1.3)days (range,5-10 days).One patient was complicated with bile leakage,6 with slight peritoneal effusion,and other patients had no postoperative complications.The rate of follow-up was 91.47％ (236/258),and the time of follow-up was (16 ± 10) months.A total of 199 patients with malignant hepatic tumors were followed up.During the follow-up,180 patients had tumor-free survival; 18 patients had postoperative tumor recurrence; 1 patient had omental metastasis and received surgical resection.Thirty-seven patients with benign hepatic tumor survived without complication during the follow-up.Conclusion Laparoscopic hepatectomy is effective for the treatment of hepatic tumors.Multiple hepatic inflow occlusion under laparoscope in a short time may improve the safety of surgery,without prolonging the recovery time of patients.
