Abstract
The surgical outcomes of robot-assisted radical prostatectomy have shown remarkable improvement over the last two decades since its advent, due to advances in surgical concepts, techniques, and equipment. Today, ongoing research aims to compare the benefits and drawbacks of various surgical approaches, such as anterior, posterior, lateral, transvesical, and transperineal approaches, in terms of tumor control, functional recovery, and complication reduction in order to achieve the goal of pentafecta (no postoperative complications and negative surgical margins in addition to trifecta) to the maximum extent. It is imperative to explore and integrate novel technologies such as 5G remote surgery and artificial intelligence into the clinical practice of robot-assisted radical prostatectomy while ensuring patient safety, which has immense potential for substantial benefits to patients with prostate cancer.

Abstract
Chronic alcohol consumption is a major risk factor for alcoholic steatohepatitis (ASH). Previous studies have shown that direct injury of hepatocytes is the key factor in its occurrence and development. However, our study shows that the role of Kupffer cells in ASH cannot be ignored. We isolated Kupffer cells from the livers of ASH mice and found that alcohol consumption induced Kupffer cell pyroptosis and increased the release of interleukin-1β (IL-1β). Furthermore, we screened the related m6A enzyme methyltransferase-like 3 (METTL3) from liver Kupffer cells, and found that silencing METTL3 alleviated inflammatory cytokine eruption by Kupffer cell pyroptosis in ASH mice. In vitro, we silenced METTL3 with lentivirus in BMDMs and RAW264.7 cells and confirmed that METTL3 could reduce pyroptosis by influencing the splicing of pri-miR-34A. Together, our results revealed a critical role of KC pyroptosis in ASH and highlighted the mechanism by which METLL3 relieves cell pyroptosis, which could be a promising therapeutic strategy for ASH.

Abstract
Background This study aims to find out the possible optimal therapy and assess the prognosis properly for patient with spontaneous rupture of hepatocellular carcinoma (HCC). Methods Propensity score matching (PSM) analysis was used to study the data from 325 patients with ruptured HCC (RHCC) and 2,291 patients with non-RHCC. Results The incidence and hospital mortality of RHCC were 5.1% and 0.8% respectively, with a median overall survival (OS) time of 17 months. There was no difference between ruptured and non-RHCC patients undergoing conservation treatment in terms of OS. Trans-arterial embolization (TAE) was carried out in 69 (21.2%) cases with RHCC, with a median OS of 7 months, which was no difference from that of non-RHCC (pre- and post-PSM). One hundred and sixty-nine (52.0%) RHCC cases underwent one-stage hepatectomy, with a median OS and disease-free survival (DFS) of 30 and 6 months respectively, which were shorter than that of non-RHCC (post-PSM). TAE plus two-stage hepatectomy was performed in 30 RHCC cases, with a median OS and DFS of 28 and 10 months respectively; these outcomes were better than that from RHCC patients undergoing TAE alone or one-stage hepatectomy (post-PSM), which were no difference from that of non-RHCC patients undergoing hepatectomy. The risk of death for RHCC patient undergoing one-stage hepatectomy is 1.545 times higher than that of one undergoing TAE + two-stage hepatectomy. Conclusions TAE plus two-stage hepatectomy might be the optimal treatment for RHCC patient. Under the premise of the same pathological properties, there is no difference in prognosis between ruptured and non-RHCC patients if the therapy is appropriate.

Abstract
Background Acute-on-chronic liver failure (ACLF) patients have high mortality in a short period of time. This study aimed to compare the prognosis of transplanted ACLF patients to that of nontransplanted ACLF patients and decompensated cirrhosis recipients. Methods Clinical data of 29 transplanted ACLF patients, 312 nontransplanted ACLF patients, and 60 transplanted decompensated cirrhosis patients were retrospectively collected. Propensity score matching (PSM) analysis was used to match patients between different groups. Results After PSM, the 90-day and 1-year survival of transplanted ACLF patients was significantly longer than that of nontransplant controls. Although the 90-day survival and 1-year survival of ACLF recipients was similar to that of decompensated cirrhosis controls, ACLF recipients were found to have longer mechanical ventilation, longer intensive care unit (ICU) stay, longer hospital stay, higher incidence of tracheotomy, higher expense, and higher morbidity of complication than matched decompensated cirrhosis controls. The 90-day and 1-year survival of transplanted ACLF grade 2–3 patients was also significantly longer than that of nontransplanted controls. Conclusions Liver transplantation can strongly improve the prognosis of ACLF patients. Despite having more burdens (including longer mechanical ventilation, longer ICU stay, higher incidence of tracheotomy, longer hospital stay, higher hospitalization expense, and higher complication morbidity), ACLF recipients can obtain similar short-term and long-term survival to decompensated cirrhosis recipients. For severe ACLF patients, liver transplantation can also significantly improve their short-term and long-term survival.

Abstract
Acute-on-chronic liver failure(ACLF) is the most severe form of acute decompensation that develops in patients with chronic liver disease or liver cirrhosis,and is always accompanied by one or more extrahepatic organ failure, and has an extremely poor short-term prognosis. The causes triggering ACLF are complex and diverse,and the clinical stage and the type and the definition of organ failure differ greatly from one another. Therefore, a universally accepted diagnostic criteria for ACLF is not to be defined, and the epidemiological data and patient outcomes on ACLF are not easy to predict and compare among different regions. Accumulating evidence has shown that liver transplantation(LT) plays a significant role in the surgical treatment of patients with ACLF,but its clinical value is still controversial. The specific management and treatment strategy after the admission of patients with ACLF has not yet formed a unified and standardized process or opinions, which includes the monitoring in the ICU,the support and maintenance of organ functions, the selection of the surgical indication and the timing for LT and so on. Moreover, there still exists many controversies concerning, for example, whether patients with ACLF should receive greater priority for organ allocation compared to other potential candidates on the waiting list. Besides, more prospective controlled studies are urgently needed to investigate the role of the artificial liver support system in the bridging therapy to LT. The aim of this article is to review the indication selection of patients with ACLF suitable for LT,the survival outcomes and prognostic factors after LT, the selection of timing, the organ allocation policy and the bridging therapy to LT, which intends to provide new direction for designing the future clinical studies on LT in patients with ACLF.

Abstract
The time-resolved magneto-optical (MO) Voigt effect can be utilized to study the Néel order dynamics in antiferromagnetic (AFM) materials, but it has been limited for collinear AFM spin configuration. Here, we have demonstrated that in Mn3Sn with an inverse triangular spin structure, the quench of AFM order by ultrafast laser pulses can result in a large Voigt effect modulation. The modulated Voigt angle is significantly larger than the polarization rotation due to the crystal-structure related linear dichroism effect and the modulated MO Kerr angle arising from the ferroic ordering of cluster magnetic octupole. The AFM order quench time shows negligible change with increasing temperature approaching the Néel temperature (TN), in markedly contrast with the pronounced slowing-down demagnetization typically observed in conventional magnetic materials. This atypical behavior can be explained by the influence of weakened Dzyaloshinskii–Moriya interaction rather than the smaller exchange splitting on the diminished AFM order near TN. The temperature-insensitive ultrafast spin manipulation can pave the way for high-speed spintronic devices either working at a wide range of temperature or demanding spin switching near TN. Mn3Sn is an anti-ferromagnetic material which displays a large magneto-optical Kerr effect, despite lacking a ferromagnetic moment. Here, the authors show that likewise, Mn3Sn, also presents a particularly large magneto-optical Voigt signal, with a negligible change in the quench time over a wide temperature range.

Abstract
Objectives: Serum biomarkers are valuable for clinical decision-making for patients with hepatocellular carcinoma (HCC), among which the most promising are AFP, AFP-L3, DCP, DKK-1, and GP73; however, the efficacy of using combined biomarkers remains controversial. This meta-analysis provides insights regarding this topic.Methods: After systematically surveying the literature available in PubMed, Embase, and Cochrane Library, we identified 28 qualified articles published since January 2015. A random-effects model was used to assess pooled sensitivity, specificity, positive and negative likelihood ratios (PLRs and NLPs), and diagnostic odds ratio (DOR).Results: Values under the summary receiver operating characteristic (SROC) curve varied in different panels of the five biomarkers. Importantly, the sum of sensitivity and specificity of AFP+GP73 was 1.76 (P= 0.0001), which was the best among all the panels. The sum of the triple biomarker panel of AFP, AFP-L3, and DCP was larger (1.64, P= 0.0001) than those of any double biomarker panels of AFP, AFP-L3, and DCP.Conclusions: To the best of our knowledge, this is the first meta-analysis to focus solely on combination assays of multiple biomarkers in HCC. The combined assay of AFP and GP73 conferred the best outcome among all panels. The triple combined panel of AFP, AFP-L3, and DCP showed higher diagnostic potential than individual random double combinations of the three biomarkers. Multiple-biomarker combined assays will be clinically important for decision-making processes for HCC.

Abstract
Immune checkpoint inhibitors are increasingly used in the treatment of various solid tumors, including hepatocellular carcinoma (HCC). For liver transplant recipients, the safety of using immune checkpoint inhibitors before or after transplantation remains to be further explored. Former reports were mainly about posttransplant use of immune checkpoint inhibitors resulting in allograft rejection. Here we present one HCC patient who received toripalimab (an immune checkpoint inhibitor currently in phase 3 clinical trial for HCC) therapy before undergoing liver transplantation. He finally suffered fatal acute hepatic necrosis which is likely to be related to the acute immune rejection caused by the pretransplant use of toripalimab.

Abstract
Objective: To systematically compare the effect of Roux-en-Y with Billroth Ⅰ or Billroth Ⅱ in gastric cancer patients after distal gastrectomy by meta-analysis. Methods: Systematic search was conducted on the relevant electronic databases of Pubmed, Embase, Wanfang Database, CNKI and VIP from the established time to August 18, 2019. The randomized controlled trials about comparison of Roux-en-Y with Billroth Ⅰ or Billroth Ⅱ were strictly screened and analyzed by the software of Revman 5.3. Procedure and postoperative outcomes were analyzed, respectively. Results: A total of 783 relevant literatures were systematically retrieved, and 6 randomized controlled trials, including 954 patients, finally met the inclusion criteria after strict screening. The results of meta-analysis showed that operative time of Billroth Ⅰ was significantly shorter than that of Roux-en-Y (MD=-37.60, 95%CI:-50.79--24.40, P<0.001), intraoperative bleeding (MD=-21.64, 95%CI:-32.20--11.07, P<0.001) and the number of delayed gastric emptying (RR=0.52, 95%CI: 0.31-0.86, P=0.01) of Billroth Ⅰ were both significantly less than those of Roux-en-Y, while bile reflux (RR=8.17, 95%CI: 2.21-31.53, P=0.002) and residual gastritis (RR=1.75, 95%CI:1.43-2.14, P<0.000 01) of Billroth Ⅰ were both significantly higher than those of Roux-en-Y, other outcomes showed no significant difference. Compared with Roux-en-Y, operative time of Billroth Ⅱ was significantly shorter (MD=-19.73, 95%CI:-32.82--6.64, P=0.003), while bile reflux (RR=17.63, 95%CI: 4.50-69.02, P<0.001), residual gastritis (RR=1.94, 95%CI:1.15-3.26, P=0.01) and reflux esophagitis (RR=3.13, 95%CI: 1.31-7.45, P=0.01) of Billroth Ⅱ were all significantly higher, and there was no significant difference in other outcomes. Conclusion: Compared with Billroth Ⅰ and Billroth Ⅱ, the operation time of Roux-en-Y in gastric cancer patients undergoing distal gastrectomy is longer, but the incidences of bile reflux and residual gastritis are both lower, and the postoperative quality of life seems better.

Abstract
The behavior of paint removal with a pulsed laser has been investigated using an Nd:YAG fiber laser. Experimental and theoretical analyses are conducted to reveal the underlying mechanism of the paint removal. The results show that the depth, radius, and volume of the pit formed by a single pulse become larger with increases in the energy density. The ideal parameters for the complete removal of paint have been achieved. During the paint removal, burning occurred over the surface, and the variation in element content has been attributed to the absorption of laser energy. Under the action of the pulsed laser, there was breakage and rearrangement of chemical bonds such as C-C, C-N, and C-O in the molecular chain of the polyacrylate paint coating. Through these analyses, the paint removal mechanism was shown to be based on chemical bond breakage, combustion, and mechanical action provided by the thermal expansion and plasma shock.

Abstract
BACKGROUND Intraoperative blood loss during hepatectomy worsens prognosis, and various tools have been used to improve perioperative safety and feasibility. We aimed to retrospectively evaluate the feasibility and safety of the BiClamp® device for open liver resection. METHODS We included 84 patients undergoing liver resection from a single centre, with all patients operated by the same surgical group. All hepatectomies were performed using BiClamp® (Erbe Elektromedizin GmbH, Tubingen, Germany), an electrosurgical device that simultaneously transects liver parenchyma and seals vessels <7 mm in diameter. We collected data on intraoperative blood loss, resection time, and perioperative complications, comparing cirrhotic and non-cirrhotic patients. RESULTS The 84 patients enrolled in this study included 56 cirrhotic and 28 non-cirrhotic patients. All patients underwent hepatectomy (30 major and 54 minor hepatectomies) using the BiClamp®, exclusively, and 54 patients required inflow occlusion (Pringle manoeuvre). Overall intraoperative blood loss (mean ± standard deviation) was 523.5 ± 558.6 ml, liver parenchymal transection time was 36.3 ± 16.5 min (range, 13-80 min), and the mean parenchymal transection speed was 3.0 ± 1.9 cm2/min. Twelve patients received perioperative blood transfusion. The cost of BiClamp® for each patient was 800 RMB (approximately 109€). There were no deaths, and the morbidity rate was 25%. The mean (standard deviation) hospital stay was 9.3 (2.3) days. Comparisons between cirrhotic and non-cirrhotic patients revealed no difference in blood loss (491.0 ± 535.7 ml vs 588.8 ± 617.5 ml, P = 0.598), liver parenchymal transection time (34.1 ± 14.8 min vs 40.9 ± 19.2 min, P = 0.208), mean parenchymal transection speed (3.3 ± 2.1 cm2/min vs 2.5 ± 1.3 cm2/min, P = 0.217), and operative morbidity (28.6% vs 14.3%, P = 0.147). CONCLUSIONS The reusable BiClamp® vessel-sealing device allows for safe and feasible major and minor hepatectomy, even in patients with cirrhotic liver. TRIAL REGISTRATION This trial was retrospectively registered and the detail information was as followed. Registration number: ChiCTR-ORC-17011873 (Chinese Clinical Trial Registry).

Abstract
AIM The treatment of large (>5 cm) hepatocellular carcinoma (HCC) remains controversial. The aim of this study was to report short and long term outcomes and analyze the factors associated with long term survival for patients who underwent hepatic resection for large HCC. METHODS All patients who underwent hepatic resection for large HCC at the department of Hepato-Pancreato-Biliary Surgery of the First Affiliated Hospital of Anhui Medical University between August 2005 and December 2011 were identified and included for analysis. Demographic and operative data, pathological findings and post-operative outcomes were entered into a computer database. Prognostic factors were analyzed by univariate and multivariate analysis. RESULTS Ninety-nine patients were included for analysis. Two patients died within 30 days of surgery secondary to hepatic failure. The 1-, 3-, 5-year disease-free survival and overall survival rates following hepatic resection were 67%, 49%, 37% and 77%, 56%, 43%, respectively. Poor histological grade was the only independent predictor of a reduced 5-year disease-free survival. Spontaneous tumor rupture and tumor recurrence were independent predictors of a reduced 5-year overall survival. CONCLUSIONS For selected patients with large HCC, hepatic resection can be performed safely and effectively with moderate expectation of long term survival. True cure however remains rare.

Abstract
Background Although various pancreaticojejunal duct-to-mucosa anastomosis methods have been developed to reduce the postoperative risks of pancreaticoduodenectomy, pancreatic fistula remains the most serious complication with a high incident rate. The aim of this study is to compare the safety and effectiveness of one-layer and two-layer duct-to-mucosa pancreaticojejunostomy in patients undergoing pancreaticoduodenectomy. Methods/design In this study, adult patients who sign consent forms will be recruited and scheduled for elective pancreaticoduodenectomy. One hundred and fourteen patients will be included and randomized before pancreaticojejunal reconstruction and after resection of the lesion from the pancreatic or periampullary region. The primary efficacy endpoint is the incident rate of postoperative pancreatic fistula. Statistical analysis will be based on the intention-to-treat population. Patients will be followed up for 3 months by monitoring for complications and other adverse events. Discussion This prospective, single-center, randomized, single-blinded, two-group parallel trial is designed to compare one-layer with two-layer duct-to-mucosa anastomosis for pancreaticojejunal anastomosis during elective pancreaticoduodenectomy.

Abstract
AIM: To determine the significance of increased serum direct bilirubin level for lymph node metastasis (LNM) in Chinese rectal cancer patients, after those with known hepatobiliary and pancreatic diseases were excluded.
METHODS: A cohort of 469 patients, who were treated at the China-Japan Friendship Hospital, Ministry of Health (Beijing, China), in the period from January 2003 to June 2011, and with a pathological diagnosis of rectal adenocarcinoma, were recruited. They included 231 patients with LNM (49.3%) and 238 patients without LNM. Follow-up for these patients was taken through to December 31, 2012.
RESULTS: The baseline serum direct bilirubin concentration was (median/inter-quartile range) 2.30/1.60-3.42 μmol/L. Univariate analysis showed that compared with patients without LNM, the patients with LNM had an increased level of direct bilirubin (2.50/1.70-3.42 vs 2.10/1.40-3.42, P = 0.025). Multivariate analysis showed that direct bilirubin was independently associated with LNM (OR = 1.602; 95%CI: 1.098-2.338, P = 0.015). Moreover, we found that: (1) serum direct bilirubin differs between male and female patients; a higher concentration was associated with poor tumor classification; (2) as the baseline serum direct bilirubin concentration increased, the percentage of patients with LNM increased; and (3) serum direct bilirubin was associated with the prognosis of rectal cancer patients and higher values indicated poor prognosis.
CONCLUSION: Higher serum direct bilirubin concentration was associated with the increased risk of LNM and poor prognosis in our rectal cancers.

Abstract
As the central protein of the double strand breaks (DSB)-induced DNA repair pathway, NBS1 participates in detecting the DSBs and plays an essential role in maintaining genomic stability. Single nucleotide polymorphisms (SNPs) in NBS1 gene were commonly tested that associated with the susceptibility to multiple cancers, but the results remained controversial. Thus, we conducted two independent hospital-based case-control studies comprising 1,072 colorectal cancer patients and 1,263 controls to evaluate the association between four NBS1 SNPs and colorectal cancer risk. The result showed that rs2735383C/G polymorphism in the 3'-untranslated region (UTR) of NBS1 was significantly associated with risk of colorectal cancer using logistic regression (P<10(-4)). Furthermore, we observed that rs2735383CC genotype was associated with substantially increased risk of colorectal cancer (odds ratio=1.55, 95% confidence interval=1.27-1.94), compared with the rs2735383GC+GG genotypes. Further functional experiments demonstrated that the rs2735383C allele in the NBS1 disrupted the binding affinity of has-miR-509-5p to the NBS1 3'-UTR in colorectal cancer cells, affecting the NBS1 transcriptional activity and expression level. In conclusion, current evidence suggests that the rs2735383C/G polymorphism might contribute to the risk for colorectal cancer.

Abstract
BACKGROUND A number of clinicopathologic factors have been found to be associated with pathological lymph node metastasis (pLNM) in rectal cancer; however, most of them can only be identified by expensive high resolution imaging or obtained after surgical treatment. Just like the Child-Turcotte-Pugh (CTP) and the model for end-stage liver disease (MELD) scores which have been widely used in clinical practice, our study was designed to assess the pre-operative factors which could be obtained easily to predict intra-operative pLNM in rectal cancer. METHODS A cohort of 469 patients who were treated at our hospital in the period from January 2003 to June 2011, and with a pathologically hospital discharge diagnosis of rectal cancer, were included. Clinical, laboratory and pathologic parameters were analyzed. A multivariate unconditional logistic regression model, areas under the curve (AUC), the Kaplan-Meier method (log-rank test) and the Cox regression model were used. RESULTS Of the 469 patients, 231 were diagnosed with pLNM (49.3%). Four variables were associated with pLNM by multivariate logistic analysis, age<60 yr (OR=1.819; 95% CI, 1.231-2.687; P=0.003), presence of abdominal pain or discomfort (OR=1.637; 95% CI, 1.052-2.547; P=0.029), absence of allergic history (OR=1.879; 95% CI, 1.041-3.392; P=0.036), and direct bilirubin ≥ 2.60 μmol/L (OR=1.540; 95% CI, 1.054-2.250; P=0.026). The combination of all 4 variables had the highest sensitivity (98.7%) for diagnostic performance. In addition, age<60 yr and direct bilirubin ≥ 2.60 μmol/L were found to be associated with prognosis. CONCLUSION Age, abdominal pain or discomfort, allergic history and direct bilirubin were associated with pLNM, which may be helpful for preoperative selection.

Abstract
Background Previous epidemiologic studies have reported that a history of allergy is associated with reduced risk of colorectal cancer and other malignancies. However, no information is available for the association between allergy and the risk of lymph node metastasis. Our study was designed to determine this association in rectal cancer. Methods Patients who were treated at our hospital in the period from January 2003 to June 2011, and with a pathologically hospital discharge diagnosis of rectal adencarcinoma, were included. The clinical, laboratory, and pathologic parameters were analyzed. A multivariate logistic regression model was used to determine the association. Moreover, for type of allergic drug, sub-group analysis was performed. Results 469 patients were included, including 231 with pathological lymph node metastasis (pLNM) (49.3%) and 238 without pLNM. Univariate analysis showed, compared with patients without pLNM, patients with pLNM had a younger age (60.6±12.8 yr vs. 63.6±12.2 yr, P = 0.012), a lower percentage of drug allergy (8.7% vs. 16.0%, P = 0.016), an increased CEA (median/interquartile-range 5.40/2.40–13.95 vs. 3.50/2.08–8.67, P = 0.009), and a lower serum sodium (141±3.1 mmol/L vs. 142±2.9 mmol/L, P = 0.028). Multivariate analysis showed that drug allergy was associated with a reduced risk of pLNM (OR = 0.553; 95% CI, 0.308–0.994; P = 0.048). In addition, our results showed that: (1) for tumor classification, patients with drug allergy had a higher percentage of group patients with pT1/pT2; and (2) for type of allergic drug, this inverse association was found for penicillins, not for other allergic drugs. Conclusion Drug allergy is associated with a reduced risk of pLNM in rectal cancer.

Abstract
OBJECTIVE To explore the efficacies of live combined Bacillus subtilis (B. subtilis) and Enterococcus faecium (E. faecium) capsules plus lactulose in the treatment of functional constipation. METHODS A total of 216 patients fulfilling the diagnostic criteria of functional constipation (slow transit pattern) were randomly enrolled from 9 participating hospitals and allocated into treatment group and control group. The patients of treatment group received lactulose plus live combined B. subtilis and E. faecium capsules for 14 days and only took the latter during the following 14 days. The patients of control group received lactulose plus placebo for 2 weeks and then only took placebo continually for the following 2 weeks. RESULTS A total of 216 patients were analyzed (treatment group n = 104, control group n = 112). The effective rates of 7-day treatment were 88.46% (n = 92) and 84.82% (n = 95) for treatment and control groups respectively. And those of 28-day treatment were 87.50% (n = 91) and 81.25% (n = 91)respectively. And the inter-group differences were not statistically significant (all P > 0.05). Fecal form, frequency, difficulty, urgency, distension, abdominal pain and expelling rates of barium enema were not statistically significant (all P > 0.05). Comparing the effective rates of 28-day with that of 14-day, differences were not statistically significant in A group (S = 0.5, P = 0.4795), but in B group the effective rates of 28-day were lower than that of 14-day statistically(S = 11, P = 0.0009). CONCLUSION The regiment of live combined B. subtilis and E. faecium capsules plus lactulose offers better efficacies in the treatment of functional constipation.

Abstract
BACKGROUND Diabetes mellitus (DM) is regarded as a new risk factor for hepatocellular carcinoma (HCC), but few studies have focused on the potential role of DM in the progression of cirrhosis to HCC as well as in patients with simple HBV infection. METHODS A cohort of 1028 patients, treated at our hospital and with a hospital discharge diagnosis of HCC and/or cirrhosis, was screened. Among them, 558 were diagnosed with chronic HBV infection and 370 were analyzed statistically according to the diagnostic, inclusion and exclusion criteria. The demographic, clinical, metabolic, virological, biochemical, radiological and pathological features were analyzed and the multivariate logistic regression model was used to determine the potential role of DM. RESULTS In 248 cirrhotic patients, 76 were diabetic and their mean duration of DM was 4.6 years. In 122 HCC patients with cirrhosis, 25 were diabetic and their mean duration of DM was 4.4 years. Univariate analysis showed that compared with cirrhotic patients, the HCC patients had a higher percentage in males (P=0.001), a lower percentage in DM patients (P=0.039), a higher percentage in cigarette smokers (P=0.005), a higher percentage in patients with AFP>400 ng/mL (P<0.001), higher values of white blood cells (P<0.001), hemoglobin (P<0.001) and platelet (P<0.001), increased levels of ALT (P<0.001) and GGT (P<0.001), higher total bilirubin (P=0.018) and albumin levels (P<0.001), and a lower international normalized ratio (P<0.001). Multivariate logistic regression analysis showed that DM was an independent associated factor for HCC [odds ratio (OR)=0.376; 95% CI, 0.175-0.807; P=0.012]. Even after the HCC patients were restricted to those with decompensated cirrhosis and compared with decompensated cirrhotic patients, the similar result was observed (OR=0.192; 95% CI, 0.054-0.679; P=0.010). CONCLUSIONS DM is an independent factor in the progression of cirrhosis to HCC, but the role may be contrary to our current viewpoint. To clarify the causal relationship of DM and HCC, prospective and experimental studies are required.

Abstract
AIM: To assess endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincteropapillotomy (EST) for common bile duct (CBD) stone removal using a meta-analysis.
METHODS: Randomized controlled trials published from 1990 to 2012 comparing EPBD with EST for CBD stone removal were evaluated. This meta-analysis was performed to estimate short-term and long-term complications of these two treatments. The fixed random effect model or random effect model was established to analysis the data. Results were obtained by analyzing the relative risk, odds ratio, and 95%CI for a given comparison using RevMan 5.1. Statistical significance was defined as P < 0.05. Risk of bias was evaluated using a funnel plot.
RESULTS: Of the 1975 patients analyzed, 980 of them were treated with EPBD and 995 were treated with EST. Of the patient population, patients in the EPBD group were younger (OR = -1.16, 95%CI: -1.49 to 0.84, P < 0.01). There were no significant differences in gender proportion, average size of stones, number of gallstones, previous cholecystectomy, the incidence of duodenal diverticulum, CBD diameter or the total follow-up time between EST and EPBD groups. Compared with EST, the total stone clearance in the EPBD group decreased (OR = 0.64, 95%CI: 0.42 to 0.96, P = 0.03), the use of stone extraction baskets significantly increased (OR = 1.91, 95%CI: 1.41 to 2.59, P < 0.01), and the incidence of pancreatitis significantly increased (OR = 2.79, 95%CI: 1.74 to 4.45, P < 0.0001). The incidence of bleeding (OR = 0.12, 95%CI: 0.04 to 0.34, P < 0.01) and cholecystitis (OR = 0.41, 95%CI: 0.20 to 0.84, P = 0.02) significantly decreased. The stone recurrence rate also was significantly reduced in EPBD (OR = 0.48, 95%CI: 0.26 to 0.90, P = 0.02). There were no significant differences between the two groups with the incidence of stone removal at first attempt, hours of operation, total short-term complications and infection, perforation, or acute cholangitis.
CONCLUSION: Although the incidence of pancreatitis was higher, the overall stone clearance rate and risk of bleeding was lower with EPBD compared to EST.

Abstract
OBJECTIVES Recent epidemiological studies suggest that metformin treatment may reduce the risks of cancer and overall cancer mortality among patients with diabetes mellitus (DM). However, data on hepatocellular carcinoma (HCC) are very limited and inconsistent. This meta-analysis was designed to pool data currently available to determine the association between metformin use and HCC among diabetic patients. METHODS The Medline and Embase databases were searched to identify the relevant studies between January 1966 and December 2011. The overall analysis was derived using a random-effects meta-analysis model (DerSimonian and Laird method). Subgroup analysis was performed to explore the source of heterogeneity and validate the results from overall analysis. The Newcastle-Ottawa Quality assessment scales were adopted for quality assessment; Begg's funnel plot and Egger's regression asymmetry test were used to detect the publication bias. RESULTS A total of seven studies were identified, including three cohort studies and four case-control studies. Based on the available data, the overall prevalence of HCC was 3.40% (562/16,549) in DM patients. The overall analysis showed a significantly reduced risk of HCC in metformin users versus nonusers in diabetic patients (relative risk (RR) 0.24, 95% confidence interval (CI) 0.13-0.46, p < 0.001). Fifteen subgroup analyses were performed, and most of them (12/15 = 80%) provided supporting evidence for the results of overall analysis. Begg's (Z = -0.15, p = 0.8819) and Egger's test (t = -0.79, p = 0.468) showed no significant risk of having a publication bias. CONCLUSION Metformin treatment was associated with reduced risk of HCC in diabetic patients. To clarify this relationship, more high-quality studies are required.

Abstract
AIM: To explore the correlation between serum-ascites albumin gradient (SAAG) and the degree of esophageal varices in patients with liver cirrhosis.
METHODS: Cirrhotic patients with ascites were collected and divided into three groups according to the degree of esophageal varices: mild group, moderate group and severe group. One-way ANOVA, correlation analysis and receiver operating characteristic (ROC) curve were used for statistical analysis.
RESULTS: A total of 43 cirrhotic patients were included in our study. One-way ANOVA indicated a significant difference in SAAG among the three groups (F = 26.317, P < 0.001). Spearman correlation analysis suggested a positive correlation between SAAG and esophageal varices (r = 0.759, P < 0. 001). ROC curve analysis indicated that the area under the ROC curve was 0.926, and the best cut-off value for diagnosis of moderate and severe esophageal varices was 20.5 g/L, with a sensitivity of 87.1% and a specificity of 83.3%.
CONCLUSION: SAAG is correlated well with the degree of esophageal varices in cirrhotic patients, and this parameter has appreciable value in diagnosis of moderate and severe esophageal varices.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) have gastrointestinal side effects such as dyspepsia, peptic ulcer, hemorrhage, and perforation. Misoprostol and PPIs have been used to prevent NSAID-induced gastroduodenal injury. Rebamipide increases gastric mucus and stimulates the production of endogenous prostaglandins. The prophylactic effect of rebamipide on NSAID-induced gastrointestinal complications is unknown. The aim of this study was to compare NSAID-induced gastrointestinal complications in rebamipide- and misoprostol-treated groups. Patients were randomized to two groups and took a conventional NSAID plus rebamipide or misoprostol for 12 weeks. Gastric mucosal damage was evaluated by endoscopy at screening and the end of the study. The prevalences of active gastric ulcer were 7/176 (3.9%) in the rebamipide group and 3/156 (1.9%) in the misoprostol group. The prevalences of peptic ulcer were 8/176 (4.5%) in the rebamipide group and 7/156 (4.4%) in the misoprostol group. The cumulative incidences of peptic ulcer in the high-risk subgroup were 6/151 (4.0%) for rebamipide and 6/154 (3.9%) for misoprostol. In conclusion, rebamipide prevented NSAID-induced peptic ulcer as effectively as misoprostol in patients on long-term NSAID therapy. Rebamipide may be a useful therapeutic option for the prevention of NSAID-induced gastrointestinal ulcer because of its therapeutic effect and safety.

Abstract
Induction of autophagy usually acts as a survival mechanism of cancer cells in response to chemotherapy. However, the function and molecular mechanism of autophagy in human hepatoma cells under drug treatment is still not clear. To address this issue, we established an experimental model in which HepG2 cells were treated with etoposide, a widely used anticancer agent. We demonstrate the etoposide-induced accumulation of GFP-LC3 dots by fluorescent microscopy, the up-regulation of LC3-II protein expression by Western blotting and the increased number of autophagic vacuoles by electron microscopy, confirming the activation of autophagy by etoposide in HepG2 cells. Inhibition of autophagy by either 3-methyladenine (3MA) or beclin-1 small interfering RNA enhanced etoposide-induced cell death. Furthermore, activation of p53 and AMPK was detected in etoposide-treated cells and inhibition of AMPK triggered apoptosis through suppression of autophagy. On the other hand, inactivation of p53 promoted cell survival through augmentation of autophagy. Collectively, these findings indicate that etoposide-induced autophagy promotes hepatoma cell adaptation and survival, and that autophagy inhibition improves the chemotherapeutic effect of etoposide. Moreover, AMPK activation is clearly associated with etoposide-induced autophagy. We conclude that manipulation of AMPK may be a promising approach of adjuvant chemotherapy for hepatocellular carcinoma.

Abstract
AIM: To determine the role of diabetes mellitus (DM) and other associated factors in Chinese hepatocellular carcinoma (HCC) patients with cirrhosis, compared with those HCC patients without cirrhosis, in the single setting of hepatitis B virus (HBV) infection, after other known concomitant diseases were excluded.
METHODS: A total of 482 patients, treated at the China-Japan Friendship Hospital, Ministry of Health (Beijing, China), in the period January 2003 to June 2009, and with a hospital discharge diagnosis of HCC, were included. Demographic, clinical, laboratory, metabolic and instrumental features were analyzed.
RESULTS: Of the total, 310 patients were diagnosed with HBV infection and, following the inclusion and exclusion criteria, 224 were analyzed, including 122 patients (54.5%) with cirrhosis (the case group) and 102 patients without cirrhosis (the control group). Twenty-seven patients (12.1%) were diabetic, including 19 in the case group and 8 in the control group (19/122 = 15.6% vs 8/102 = 7.8%, P = 0.077). Thirty-one possible relevant parameters were compared by univariate analysis, and 9 variables were selected for multivariable analysis, including DM (P = 0.077), past history of HBV infection (P = 0.005), total bilirubin (P < 0.001), albumin level (P < 0.001), international normalized ratio (INR) (P < 0.001), alanine aminotransferase (P = 0.050), platelet (P < 0.001), total cholesterol (P = 0.047), and LDL cholesterol (P = 0.002) levels. Diabetes showed a statistical difference by multivariable analysis [odds ratio (OR) 4.88, 95% confidence interval (CI): 1.08-21.99, P = 0.039], although no significant difference was found in univariate analysis. In addition, three cirrhosis-related parameters remained statistically different, including INR (OR 117.14, 95% CI: 4.19-3272.28, P = 0.005), albumin (OR 0.89, 95% CI: 0.80-0.99, P = 0.027), and platelet count (OR 0.992, 95% CI: 0.987-0.999, P = 0.002).
CONCLUSION: Besides the three cirrhosis-related parameters, DM was found to be the sole independent factor associated with HCC in patients with HBV-related cirrhosis, compared with those without cirrhosis.

Abstract
AIM: To investigate the role of oxidative stress reaction in the pathogenesis of chronic hepatic injury induced by alcohol and carbon tetrachloride (CCl4) in rats.
METHODS: Fifty male Wistar rats were divided equally into five groups: A, B, C, D and E. The experiment was continued for 8 weeks in each group. Groups A and B were perfused intragastrically with normal saline and alcohol, respectively. Group C was treated as group B and additionally injected intraperitoneally with prostaglandin E1 (PGE1). Group D was perfused intragastrically with alcohol for 4 weeks and injected intraperitoneally with CCl4 for another 4 weeks. Group E was treated as group D and additionally injected intraperitoneally with PGE1. At weeks 4 and 8, serum ALT, AST, ALP, TBA, TG, CHO, GSH-Px, and MDA were determined. At week 8, all rats were executed to take hepatic tissue specimens for observation of histopathological alterations.
RESULTS: No significant differences were found in the original body weight (BW) among the five groups before the treatment. Compared with group A, at week 8, the BW and increased BW significantly decreased (249.00 g ± 18.83 g and 258.50 g ± 20.28 g vs 319.00 g ± 29.61 g; 65.00 g ± 15.28 g and 76.50 g ± 15.82 g vs 134.00 g ± 21.58 g, respectively; all P < 0.01), and the liver mass (expressed as the percentage of total BW) significantly increased (3.267% ± 0.3165% and 4.735% ± 0.7567% vs 2.736% ± 0.1988%, respectively; both P < 0.01) in groups B and D. After pre-treatment with PGE1 (groups C and E), the decrease in body weight and the increase in liver mass were improved (all P < 0.01). Alcohol and CCl4 (groups B and D) elevated serum ALT, AST, ALP, TBA, TG, CHO and MDA levels (all P < 0.01 or 0.05), and reduced serum GSH-Px levels (both P < 0.01). After intervention with PGE1, these parameters were improved. In addition, PGE1 pre-treatment could mitigate hepatocyte fatty degeneration, cellular necrosis, inflammatory infiltration and liver fibrosis induced by alcohol and CCl4.
CONCLUSION: Oxidative stress may play an important role during chronic liver injury induced by alcohol and CCl4. Inhibition of oxidative stress may be an important measure for alleviating liver injury.

Abstract
AIM: To study expression and correlation between CTHRC1 and VEGF-C in human rectal carcinoma.
METHODS: Ninety-eight patients diagnosed with rectal carcinoma at China-Japan Friendship Hospital from October 2004 to August 2008, were included in our study. No treatment was given before surgery and the specimens were collected after surgery. The expression of CTHRC1 and VEGF-C was examined by immunohistochemistry and the correlation with clinical characteristics was analyzed by SPSS10.0.
RESULTS: VEGF-C was mainly located in the tumor cells, and its expression was statistically correlated with tumor differentiation, clinical stages and lymph metastasis (P < 0.05). The expression of CTRHC1 was correlated with the clinical stages and tumor differentiation (P < 0.05), both of the expressions had no correlation with the age or gender of patients. Moreover, a positive correlation was observed between VEGF-C and CTHRC1 by correlative analysis (r = 0.629, P < 0.001).
CONCLUSION: CTHRC1 and VEGF-C may play important roles in invasion and metastasis in human rectal carcinoma. The two biomarkers can be applied to assess the malignancy of rectal cancer.

Abstract
AIM: To develop a conditionally replicative gene-viral vector system called CNHK500-p53, which contains dual promoters within the E1 region, and combines the advantages of oncolytic virus and gene therapies for hepatocellular carcinoma (HCC).
METHODS: CNHK500-p53 was constructed by using human telomerase reverse transcriptase (hTERT) promoter to drive adenovirus E1a gene and hypoxia response element (HRE) promoter to drive adenovirus E1b gene. p53 gene expressing cassette was inserted into the genome of replicative virus. Viral replication experiments, cytopathic effect (CPE) and methyl thiazolyl tetrazolium (MTT) assay were performed to test the selective replication and oncolytic efficacy of CNHK500-p53.
RESULTS: Immunohistochemistry verified that infection with CNHK500-p53 was associated with selective replication of adenovirus and production of p53 protein in telomerase-positive and hypoxia-inducible factor-dependent HCC cells. p53 protein secreted from HepG2, infected with CNHK500-p53 was significantly higher than that infected with nonreplicative adenovirus Ad-p53 in vitro (388 ± 34.6 μg/L vs 76.3 ± 13.17 μg/L). Viral replication experiments showed that replication of CNHK500-p53 and CNHK500 or WtAd5, was much stronger than that of Ad-p53 in tested HCC cell lines. CPE and MTT assay indicated that CNHK500-p53 selectively replicated in and killed HCC cells while leaving normal cells unaffected.
CONCLUSION: A more efficient gene-viral system is developed by combining selective oncolysis with exogenous expression of p53 against HCC cells.

Abstract
AIM: To investigate whether microvessel density (MVD) is related with prognosis in gastric cancer patients, and the expression of cyclooxygenase-2 (COX-2) and vessel endothelial growth factor (VEGF) so as to determine the possible role of COX-2 and VEGF in gastric cancer angiogenesis.
METHODS: Forty-seven formalin-fixed paraffin-embedded tissue samples of gastric cancer were evaluated for COX-2, VEGF by immunohistochemical staining. To assess tumor angiogenesis, MVD was determined by immunohistochemical staining of endothelial protein factor VIII-related antigen. The relationship among COX-2 and VEGF expression, MVD, and clinicopathologic parameters was analyzed.
RESULTS: Among the 67 samples, high MVD was significantly associated with lymph node metastasis and poor survival. Multivariate survival analysis showed that MVD value and lymph node metastasis were independent prognostic factors. The expression rate of COX-2 and VEGF was significantly higher than that of the adjacent tissues. COX-2 and VEGF expression in gastric cancer was significantly correlated with tumor differentiation and depth of invasion, but not with survival. The mean MVD value of COX-2 or VEGF positive tumors was higher than that of COX-2 or VEGF negative tumors. A significant correlation was found between the expressions of COX-2 and VEGF.
CONCLUSION: MVD may be one of the important prognostic factors for gastric cancer patients. COX-2 and VEGF may play an important role in tumor progression by stimulating angiogenesis. VEGF might play a main role in the COX-2 angiogenic pathway. The inhibition of angiogenesis or COX-2, VEGF activity may have an important therapeutic benefit in the control of gastric cancer.

Abstract
We used simulated microgravity to treat aged pea seeds, in order to observe its effect on seed vigour and related physiological properties. The result shows that microgravity obviously promotes the germination rate, vitality index, germination index, and keeps the activity of protective enzyme, with conductivity and the content of MDA decreased. These effects gradually disappeared for a certain period after the microgravity administration.

Abstract
AIM To determine the enoxacin by means of terbium sensitized chemiluminescence in pharmaceutical preparations as well as urine samples. METHODS Through six-way injection valve Ce4+, H2SO3, Tb3+ and enoxacin (ENX) standard solutions were injected into the flow system in a certain order, the chemiluminescence signal was detected by weak luminescence analyzer. RESULTS The chemiluminescence intensity was linearly related to the concentration of ENX in the range of 2.0 x 10(-9)-6.0 x 10(-8) mol.L-1 with a detection limit of 4.0 x 10(-10) mol.L-1. Relative standard deviation was less than 1.6% (n = 11). CONCLUSION It provides a sensitive rapid, simple and accuracy measurement of enoxacin for the pharmacokinetic studies.
