Chemotherapy is one of the major approaches for the treatment of metastatic lung cancer, although it is limited by the low tumor delivery efficacy of anticancer drugs. Bacterial therapy is emerging for cancer treatment due to its high immune stimulation effect; however, excessively generated immunogenicity will cause serious inflammatory response syndrome. Here, we prepared cancer cell membrane-coated liposomal paclitaxel-loaded bacterial ghosts (LP@BG@CCM) by layer-by-layer encapsulation for the treatment of metastatic lung cancer. The preparation processes were simple, only involving film formation, electroporation, and pore extrusion. LP@BG@CCM owned much higher 4T1 cancer cell toxicity than LP@BG due to its faster fusion with cancer cells. In the 4T1 breast cancer metastatic lung cancer mouse models, the remarkably higher lung targeting of intravenously injected LP@BG@CCM was observed with the almost normalized lung appearance, the reduced lung weight, the clear lung tissue structure, and the enhanced cancer cell apoptosis compared to its precursors. Moreover, several major immune factors were improved after administration of LP@BG@CCM, including the CD4⁺/CD8a⁺ T cells in the spleen and the TNF-α, IFN-γ, and IL-4 in the lung. LP@BG@CCM exhibits the optimal synergistic chemo-immunotherapy, which is a promising medication for the treatment of metastatic lung cancer.

Objective To investigate the feasibility of liver transplantation in the treatment of inoperable hilar cholangiocarcinoma. Methods The clinical data for 3 patients with unresectable hilar cholangiocarcinoma who underwent liver transplantation in the Department of Hepatobiliary Surgery of Fuzhou General Hospital of People's Liberation Army from January 2006 to December 2012 were retrospectively analyzed. The patients were followed up by phone, outpatient service, and hospitalization. The starting point of the follow-up was the operation date. The patients death was the end point. The clinical and pathological features, postoperative survival, tumor recurrence, and prognostic factors were observed. The follow-up deadline was December 2017. Results All 3 patients underwent classical orthotopic liver transplantation using retrograde perfusion through inferior vena cava and no perioperative deaths occurred. All 3 patients were followed up for 10 to 132 months. During the follow-up period, of 1 patient who died of tumor recurrence, the pathological TNM stage was T4a N1 M0, and both had Union for International Cancer Control stage Ⅳa, and the tumor-free survival time was 3 months, and the survival time was12 months. Of 1 patient who died of other causes, the pathological TNM stage was T3N1 M0, and both had Union for International Cancer Control stage Ⅲ, and the tumor-free survival time was 12 months, and the survival time was12 months. One case as of the end of follow-up, the patient has survived for 132 months, the pathological TNM staging was T2a NOM0, and both had Union for International Cancer Control stage Ⅱ. Conclusions Lymph node positive and high pathological TNM stage were poor prognosis factor for hilar cholangiocarcinoma who underwent liver transplantation. Patients with early hilar cholangiocarcinoma who don't have lymph node metastasis are expected to benefit from liver transplantation.

Objective: To investigate the mechanism of apoptosis of CD8⁺T lymphocyte in peripheral blood of patients with hepatocellular carcinoma (HCC). Methods: The proportion and apoptosis of peripheral blood CD8⁺T lymphocytes in 30 healthy controls, 30 patients with cirrhosis and 60 HCC patients were detected by Flow cytometry, and the expression of Fas on the surface of CD8⁺T lymphocytes was reported. The differences between groups were compared using independent sample t-test, and data of variance were tested with Mann-Whitney U non-parametric test, P < 0.05 was considered statistically significant. Results: The proportion of CD8⁺T lymphocytes in peripheral blood of patients with HCC was 26.4% ± 9.2%, higher than that of 24.5% ± 7.1% in cirrhosis (t = 0.783, P = 0.489), and and healthy control 19.7% ± 4.7% (t = 2.920, P = 0.004). The proportion of apoptotic CD8⁺T lymphocytes in peripheral blood of HCC patients was 25.3% ± 6.5%, of the total CD8⁺T lymphocytes, which was significantly higher than that of healthy controls 12.1%±6.5% (t = 7.555, P < 0.001) and cirrhotic 13.6% ± 5.8% (t = 5.213, P < 0.001), the differences were statistically significant. The proportion of Fas⁺CD8⁺T lymphocytes in the HCC group was 62.2% ± 18.5%, higher than that in the healthy control group 42.6%±16.5% (t = 4.127, P < 0.001) and 46.1% ± 14.5% (t = 2.561, P < 0.01)of the cirrhosis group, the differences were statistically significant. Fas expression was positively correlated with the apoptosis of CD8⁺T lymphocytes (r ² = 0.113, P < 0.05). Conclusion The proportion of CD8⁺T lymphocytes in peripheral blood of patients with HCC is higher than that of healthy controls, but the proportion of CD8⁺T lymphocyte apoptosis based on Fas/FasL pathway increased, which may be an important mechanism for tumor cell immune escape.

Objective To investigate the biliary complications and recovery of liver function after liver transplantation from citizen's deceased donors (DCD) versus standard criteria donors (SCD).Method The clinical data of 269 patients who underwent orthotopic liver transplantation from January 2009 to December 2016 at the Fuzhou General Hospital were collected.197 livers were from SCD and 72 from DCD.Propensity score matching (PSM) was used to compare the biliary complications and recovery of liver function after liver transplantation in the two groups.Results PSM matched 61 pairs of patients.There were 10 (16.4％) and 8 (13.1％) biliary complications in the DCD and the SCD groups,respectively,with no significant difference between them (P ＞ 0.05).The recovery of liver function was significantly delayed in the DCD group when compared with the SCD group.The levels of ALT,AST,GGT and AKP in the DCD group were significant different on the postoperative first,third,fifth,seventh and fourteenth day (P ＜ 0.05).At 30 days after surgery,there was no significant difference in liver function between the two groups.Conclusions Liver grafts from DCD had a significant impact on the recovery of liver function.When compared with the SCD group,the DCD group recovered significantly slower in liver function.There was no significant increase in the incidence of biliary complications.

Objective To investigate the expression of long-chain non-coding RNA gastric cancer high expression transcription factor 1 (GHET1) in hepatocellular carcinoma (HCC) and the correlation with prognosis,cell proliferation,migration and invasion.Methods 20 HCC patients who underwent surgery from Fuzhou General Hospital of Chinese People's Liberation Army from March to May 2016 were included.The HCC tissue and adjacent normal tissue of 182 patients from June 2012 to December 2013 were retrospectively collected.According to the median value of GHET1 expression,it was divided into GHET1 high expression group and low expression group,91 cases each.Huh7 and HepG2 cells were divided into:blank control group (Con) with serum-free medium,siRNA-GHET1 group transfected with siRNA-GHET1,and negative control group (siRNA-NC) transfected with negative control sequence.The expression of GHET1 was detected by real-time fluorescence quantitative polymerase chain reaction,and the effect of GHET1 on HCC cells was analyzed by CCK-8,Transwell assay and Western blot.Results Compared with adjacent normal tissue,the relative expression of GHET1 mRNA in HCC tissues was significantly increased.Compared with LO2 cells,the mRNA expression of GHET1 in Huh7 and HepG2 cells was higher (P＜0.05).The GHET1 high expression group had tumor＞5 cm,vascular invasion,AFP＞400 μg/L,Edmonson grade Ⅰ,and the tumor-free ratio was lower in the expression group (P＜0.05).Survival analysis showed that HCC patients with high GHET1 expression had a poorer prognosis than patients with low expression.Multivariate Cox regression analysis showed that high expressed GHET1,vascular invasion (HR=2.067,95％ CI:1.350 to 3.162),and without tumor capsule are independent predictors of recurrence in HCC patients.After transfection with Huh7 and HepG2 cells,the proliferation of siRNA-GHET1 group was significantly decreased comparing with Con and siRNA-NC groups.Compared with siRNA-NC group,the migration and invasion ability of siRNA-GHET1 group decreased,and E-cadherin expression increased.The expression of fibronectin and vimentin decreased,and the difference was statistically significant (P＜0.05).Conclusions The expression of GHET1 in HCC tissue is higher comparing with normal tissue,which increases the proliferation,migration and invasion of hepatoma cells.It is an independent predictor of prognosis in HCC patients and a potential target for clinical treatment.

Objective To compare the safety and efficacy of laparoscopic and open left hepatectomy for hepatocellular carcinoma (HCC).Methods Clinical data of 31 patients with HCC who underwent left hepatectomy in the First People's Hospital of Foshan from June 2011 to December 2017 were retrospectively analyzed.Among 31 patients,24 cases were male and 7 female,aged from 11 to 78 years with a median age of 58 years.Patients were divided into laparoscopic left hepatectomy group (laparoscopic group,n=17) and open left hepatectomy group (open group,n=14).The informed consents of all patients were obtained and the local ethical committee approval was received.In laparoscopic group,two-step Endo-GIA laparoscopic left hepatectomy was performed,and conventional hepatectomy was performed in open group.The postoperative length of hospital stay was compared by t test.The intraoperative blood loss was compared by rank-sum test.The incidence of postoperative complications was compared by Chisquare test.Results All patients underwent operation successfully without perioperative death.The median intraoperative blood loss in laparoscopic group was 100(50-500) ml,significantly less than 325(50-900) ml in open group (Z=-2.180,P＜0.05).The postoperative length of hospital stay in laparoscopic group was (8.4±2.3) d,significantly shorter than (10.9±2.5) d in the open group (t=-2.869,P＜0.05).5 cases developed postoperative pleural effusion in laparoscopic group,and 5 in open group,where no significant difference was observed (x2=0.140,P＞0.05).Conclusions Laparoscopic left hepatectomy is safe for HCC and has similar efficacy as open surgery,the intraoperative blood loss is less comparatively and postoperative recovery time is shorter,which can serve as a standard surgical approach in clinical practice.

Objective To investigate the role of preoperative peripheral blood neutrophil to lymphocyte ratio (NLR),platelet to lymphocyte ratio (PLR),prognostic nutritional index (PNI) in the prognosis of patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after radical operation.Methods This is a retrospective study,involving 426 surgically resected hepatitis B related hepatocellular carcinoma cases in a single center from 2003 to 2012.Results Kaplan-Meier analysis showed patients in NLR ≤ 1.62 group achieve higher rate of recurrence-free and overall survival than that in the NLR ＞ 1.62 group,the difference was statistically significant (P ＜ 0.005);Also PNI ＞ 49.42 group showed higher rate of overall survival significantly than PNI≤49.42 group (P ＜ 0.005).The results of Cox regression multivariate analysis further suggested that both NLR ＞ 1.62 (HR 1.74,P =0.007) and PNI ≤49.42 (HR 0.70,P =0.021) were independent risk factors for overall survival,NLR ＞ 1.62 (HR 1.45,P =0.03) was also an independent risk factor for recurrence-free survival.Conclusion The preoperative NLR and PNI may be independent risk factors for prognosis of patients with HBV-related HCC after radical operation.

Background and purpose:Thermal ablation (radiofrequency ablation, RFA/microwave ablation, MWA) is the most commonly used minimally invasive technique for the treatment of liver cancer. Real-time shear wave elastography (SWE) is a new type of ultrasonic imaging technology, which was used in our study to monitor thermal ablation of liver cancer. This study aimed to investigate the stiffness change of liver cancer and that of surrounding liver parenchyma before and after thermal ablation, and to evaluate the application of SWE for monitoring thermal ablation for liver cancer.Methods:From Oct. 2014 to Apr. 2015, a total number of 36 patients, with 39 lesions, were treated with RFA or MWA and got complete response. SWE examination was performed before and after ablation. The SWE-mean, SWE-min, SWE-max, SWE-SD of lesions and the surrounding liver parenchyma were measured. Statistical analysis was made to compare the stiffness changes of liver cancer with those of the surrounding liver parenchyma before and after thermal ablation, and to determine whether there were differences between two different ablation modes.Results:Before and after ablation, the SWE-mean of lesions was (30.09±11.67) kPavs (52.11±17.56) kPa,SWE-min was (10.46±8.22) kPavs (20.57±11.42) kPa, SWE-max was (51.50±20.84) kPavs (88.54±27.75) kPa, SWE-SD was (10.63±4.30) kPavs (16.89±7.72) kPa; There were statistically signiifcant differences (P<0.05). Before and after ablation, the SWE-mean of surrounding liver parenchyma was (8.84±2.82) kPavs (8.91±2.78) kPa, SWE-min was (4.77±1.95) kPavs (4.69±1.90) kPa, SWE-max was (13.82±3.79) kPavs (14.34±3.97) kPa, SWE-SD was (3.24±1.32) kPavs (3.37±1.29) kPa; There were no statistically signiifcant differences (P>0.05). After ablation, the SWE-mean of RFA and MWA was (45.55±10.91) kPavs (60.59±20.99) kPa, SWE-min was (18.95±8.86) kPavs (25.93±10.93) kPa, SWE-max was (76.58±15.51) kPavs (104.01±32.59) kPa, SWE-SD was (13.82±3.52) kPavs (20.85±9.77) kPa; There were statistically signiifcant differences (P<0.05).Conclusion:SWE can quantitively analyze the stiffness of lesions. The ablation zone became stiffer after RFA or MWA, and the ablation zone of MWA was stiffer than that of RFA. Two kinds of ablation methods did not signiifcantly affect the stiffness of liver parenchyma around the lesion. SWE could potentially be used to monitor thermal ablation of liver cancer.

OBJECTIVETo conduct a systematic review of the safety and efficacy of enhanced recovery after surgery(ERAS) program in perioperative management of pancreaticoduodenectomy.

METHODSA computerized search was performed in databases including PubMed, Embase, Medline, Web of Science, Cochrane Library, CNKI, Wanfang and VIP for randomized controlled trials (RCTs) or clinical controlled trials (CCTs) describing an ERAS program in patients undergoing pancreaticoduodenectomy published between January 1966 and May 2014. After assessment of methodological quality and data extraction, meta-analysis was performed using RevMan 5.2.0 software.

RESULTSSix RCTs and 8 CCTs including 2565 patients were selected for this study, including the study group(n=1366) and the control group (n=1199). Compared with the control group, the study group had a shorter length of hospital stay(WMD=-3.67, 95% CI:-5.66--1.68, P<0.05), lower postoperative complication rate(OR=0.73, 95% CI:0.56-0.95, P<0.05) and lower mortality(OR=0.63, 95% CI:0.44-0.91, P<0.05). However, no significant differences existed in mortality, readmission rate and re-operation rate between the two groups.

CONCLUSIONSEnhanced recovery after surgery programme in perioperative management of pancreaticoduodenectomy is safe and effective. But due to the medium quality of the literature. This still need more rigorously designed RCTs to prove the safety and efficiency of ERAS programme for the patients undergoing pancreaticoduodenectomy.
