Abstract
Objective: To investigate the vitamin A nutritional status of 6- to 17-year-old urban children and adolescents by analyzing serum retinol level, between 2010 and 2012 in China. Methods: Data were obtained from the China Nutrition and Health Survey in 2010-2012. Using multi-stage stratified sampling and the population proportional stratified random sampling method, 6 617 children aged 6-17 years from 32 metropolis and 41 middle-sized and small cities of China were selected. The questionnaire survey was used to collect demographic information. Blood samples were analyzed using high-performance liquid chromatography to determine serum retinol concentration, and the World Health Organization guidelines were used to evaluate the nutritional status of vitamin A. Vitamin A levels, vitamin A deficiency, and marginal vitamin A deficiency in children with different characteristics were compared. Results: A total of 3 785 cases with valid samples were obtained. The overall mean serum retinol concentration level was (1.49±0.71) μmol/L; the mean serum retinol concentration was (1.55±0.69) μmol/L for metropolis and (1.49±0.75) μmol/L for middle-sized and small cities (P>0.05). The mean serum retinol concentration was (1.52±0.78) μmol/L for boys and (1.47±0.68) μmol/L for girls (P>0.05). The mean serum retinol concentration level was (1.46±0.70) μmol/L for 6- to 11-year-old children and (1.54±0.65) μmol/L for 12- to 17-year-old children (P<0.05). The total vitamin A deficiency rate and marginal vitamin A deficiency rate was 7.69% (291/3 785) and 18.57% (703/3 785), respectively. The vitamin A deficiency rate was 8.00% (36/450) for metropolis and 7.64% (65/3 335) for middle-sized and small cities; 8.12% (155/1 908) for boys and 7.25% (136/1 877) for girls; and 8.04% (171/2 115) for 6- to 11-year-old children and 7.18% (120/1 670) for 12- to 17-year-old children. No significant differences were observed for region, sex, or age (P>0.05). The marginal vitamin A deficiency rate was 19.11% (86/450) for metropolis and 18.50% (617/3 335) for middle-sized and small cities; 18.19% (347/1 908) for boys and 18.97% (356/1 877) for girls, with no significant differences observed (P>0.05). The marginal vitamin A deficiency rate was 16.54% (350/2 115) for 6- to 11-year-old children and 21.13% (353/1 670) for 12- to 17-year-old children (P<0.05). Conclusion: The vitamin A nutritional status of 6- to 17-year-old Chinese urban children and adolescents between 2010 and 2012 has improved, and the gap between cities is narrowing. However, vitamin A deficiency overall remains high, especially in younger children, and requires specific attention.

Abstract
The spotted knifejaw, Oplegnathus punctatus, is an important aquaculture fish species in China. To better understand the chromosomal microstructure and the karyotypic origin of this species, cytogenetic analysis was performed using Giemsa staining to identify metaphase chromosomes, C-banding to detect C-positive heterochromatin, silver staining to identify the nucleolus organizer regions (Ag-NORs), and fluorescence in situ hybridization (FISH) for physical mapping of the major (18S rDNA) and minor (5S rDNA) ribosomal genes. The species showed a karyotype of 2n = 48 for females, composed of 2 submetacentric and 46 telocentric chromosomes, with a fundamental number (FN) = 50, while the karyotype of males was 2n = 47, composed of 1 exclusive large metacentric, 2 submetacentric, and 44 telocentric chromosomes, with FN = 50. These karyotype results suggest that O. punctatus might have an X1X1X2X2/X1X2Y multiple sex chromosome system. C-positive heterochromatin was distributed in the centromeres of all chromosomal pairs and in the terminal portions of some chromosomes. A single pair of Ag-positive NORs was found to be localized at the terminal regions of the short arms of the subtelocentric chromosome pair, which was supported by FISH of 18S rDNA. After FISH, 5S rDNA were located on the interstitial regions of the smallest telocentric chromosome pair. This study was the first to identify the karyotype of this species and will facilitate further research on karyotype evolution in the order Perciformes.

Abstract
Objective: Discuss the surgical options for the chronic pancreatitis on the basis of anatomical morphological changes. Methods: A retrospective review of chronic pancreatitis patients in Department of Pancreatic Surgery, West China Hospital, Sichuan University between January 2010 and December 2014 was performed. The data of medical records, image feature, surgical types and records of follow-up were collected. Total 295 patients including 275 male and 20 female aged from 14 to 74 years with median age of 51 years. The clinical symptoms included abdominal pain in 280 cases, jaundice in 3 cases, single hemorrhage in digestive tract, diarrhea or mellitus in 12 cases. The anatomical morphological changes included pancreatic fibrosis and atrophy of the main pancreatic duct lesions in 44 cases (14.9%), inflammatory mass in the pancreatic head in 69 cases (22.4%), sporadic stones with calcification in the pancreatic head in 165 cases(55.9%), hyperplasia mass of pancreatic head and body in 14 cases (4.8%), sporadic stones with calcification in whole branch ducts accompanied with different degree of hyperplasia in whole pancreas in 3 cases (1.0%). The surgical options included longitudinal pancreaticojejunostomy, duodenum-preserving pancreatic head resection, Frey/Frey+ distal pancreatectomy, total and subtotal pancreatectomy. All patients were followed-up for 3 to 6 months in the outpatient. A cross-sectional study was carried out by telephone, letters, questionnaire and outpatient from April to June 2016. Results: Among 295 patients, 267 cases were followed-up for an average time of 40 months(18 to 78 months), 28 cases were lost to followed-up(9.5%). Pain remission rate of pancreatic fibrosis and atrophy of the main pancreatic duct lesions patients was 97.0%, of inflammatory mass in the pancreatic head patients was 96.8%, of sporadic stones with calcification in the pancreatic head patients was 96.6%, of hyperplasia mass of pancreatic head and body patients was 12/13, of sporadic stones with calcification in whole branch ducts accompanied with different degree of hyperplasia in whole pancreas patients was 3/3. There were 19 cases(9.6%) with blood glucose rising. Conclusion: According to the pathological changes of chronic pancreatitis, the reasonable choice of surgical procedures can be done to maximize the removal of the cause of pain and the preservation of pancreatic tissue.

Abstract
Interferon regulatory factor 6 (IRF6) is a novel and unique member of the IRF family of transcription factors, and the regulation and function of IRF6 remain unknown. Recently, IRF6 was shown to be upregulated after TBI and could promote neuronal apoptosis under oxidative stress conditions. This study aimed to investigate the role of IRF6 in traumatic neuronal injury (TNI) in primary cultured mouse cortical neurons. We found that the expression of IRF6 was significantly increased within 48 after TNI, and peaked at 24 h. Knockdown of IRF6 using specific targeted small interfering RNA (siRNA) attenuated TNI-induced loss of neuronal viability and release of lactate dehydrogenase. The results of TUNEL staining showed that IRF6 knockdown markedly reduced neuronal apoptosis, which was accompanied by decreased activity of caspase-3. Furthermore, downregulation of IRF6 inhibited lipid peroxidation, promoted the activity of endogenous antioxidative enzymes, and differently regulated the expression of inflammatory cytokines after TNI. In addition, IRF6 knockdown significantly increased phosphorylation of Akt and endothelial nitric oxide synthase (eNOS), whereas blocking Akt-eNOS pathway via selective antagonists partly prevented the protective effects of IRF6 knockdown. These data show that downregulation of IRF6 affords protection against TNI through Akt-eNOS pathway-mediated antioxidative and anti-inflammatory activity.

Abstract
Previous studies have suggested that the tumor necrosis factor alpha (TNF-α) gene 308G/A polymorphism may be associated with polycystic ovary syndrome (PCOS) risk. However, this relationship is controversial. The present meta-analysis aimed to evaluate the correlation between the TNF-α308G/A polymorphism and susceptibility to PCOS. A systematic electronic search of PubMed and Embase databases was conducted using specific inclusion criteria. Summary odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated, and all statistical analyses were performed using STATA 12.0. The results of our meta-analysis showed no significant association between the TNF-α308G/A polymorphism and PCOS risk (AA vs GG: OR = 0.80, 95%CI = 0.31-2.08; AG vs GG: OR = 1.03, 95%CI = 0.59-1.81; dominant model: OR = 1.02, 95%CI = 0.60-1.71; recessive model: OR = 0.87, 95%CI = 0.35-2.16). Based on the statistical data, our meta-analysis indicates that the TNF-α308G/A sequence variation may be not related to PCOS susceptibility. Further large and well-designed studies are needed to confirm this conclusion.

Abstract
AIM: To investigate the effect of Euphorbia esula (E. esula) extract in inhibiting proliferation and inducing apoptosis in SGC-7901 cells.
METHODS: E. esula extract at different concentrations was used to inhibit proliferation and induce apoptosis of human gastric carcinoma SGC-7901 cells. Inhibition of proliferation was detected with thiazolyl blue assay, and apoptosis was detected with fluorescence microscopy, transmission electron microscopy, and flow cytometry. The mechanisms were studied by measurement of caspase-3 and caspase-8 activities and Bax and Bcl2 mRNA expression.
RESULTS: The thiazolyl blue assay showed that SGC-7901 cell viability and proliferation were inhibited significantly by E. esula extract in a time- and concentration-dependent manner. Fluorescence microscopy revealed that the cell nuclei showed the characteristic changes of apoptosis, such as uneven staining and chromatin marginalization. Some key features of apoptosis were also observed under transmission electron microscopy, which included cellular shrinkage and the foaming or bubbling phenomenon. When the cells were analyzed by flow cytometry, a sub-G1 peak could be seen clearly. Spectrophotometric assay of caspase-3 and caspase-8 activities in the treated cells showed an approximately two-fold increase. Reverse transcription polymerase chain reaction showed that Bax mRNA expression was upregulated, while Bcl2 mRNA expression was downregulated.
CONCLUSION: E. esula extract inhibited proliferation and induced apoptosis in SGC-7901 cells, in a caspase-dependent manner, involving upregulation of Bax and downregulation of Bcl2.

Abstract
OBJECTIVE To analyze the viability of extended distal pancreatectomy and the associated prognostic factors. METHODS The data of 57 patients with pancreatic adenocarcinoma who underwent standard distal pancreatectomy(DP) or extended distal pancreatectomy(EDP) from January 2011 to December 2014 were reviewed retrospectively. Thirty-five patients were performed with DP and 22 with EDP. Operation safety and survival benefit between DP and EDP were compared by t-test or χ(2) test.Cox regression analysis was used to explore the prognostic indicators. RESULTS Compared to DP group, operation time((255±91)min vs.(208±80)min)(t=2.066, P=0.044) and ratio of blood transfusion (50.0% vs.17.1%)(χ(2)=12.836, P=0.008) were greater in EDP group, respectively.There were no significant differences in amount of intraoperative blood loss and postoperative duration of hospitalization. Delayed gastric emptying was greater in EDP(22.7% vs.2.9%)(Z=-2.251, P=0.027), while other complications had no differences. Mortality and ratio of relaparotomy also showed no differences. Median survival following DP was 13.1 months compared to 8.2 months following EDP. There was no difference in survival between DP and EDP. According to the results of multivariate analysis, tumor size(RR=1.275, P=0.03)and perioperative blood transfusions(RR=2.673, P=0.04) were independent prognostic factors. CONCLUSIONS Though patients with pancreatic adenocarcinoma who undergo EDP have a worse pathologic staging, they will gain a comparable long-term survival to the patients undergo DP. Tumor size and perioperative blood transfusions are independent prognostic factors.

Abstract
AIM Clematis terniflora DC. has been widely used as a traditional Chinese medicine for the treatment of tonsillitis, rheumatoid arthritis, and prostatitis. Despite its widespread use in China, there are currently no studies systematically examined its therapeutic effects and mechanism of action. As such, the present study was conducted to evaluate the anti-inflammatory, antinociceptive, and immunomodulatory effects of C. terniflora DC. using rodent and cellular models. METHODS The anti-inflammatory properties of the 70% ethanol eluted fraction of the 70% ethanol extract of C. terniflora DC. (EECTD) were evaluated using the xylene-induced ear swelling test, the carrageenan-induced edema model, and the cotton pellet granuloma method. Its antinociceptive activities were determined using both the acetic acid-induced writhing test and the hot plate assay. In parallel, we conducted an in vitro assay in LPS-induced RAW264.7 cells to examine the anti-inflammatory effects of EECTD and its purified form, aurantiamide acetate (AA) on inhibition of nitric oxide (NO) and prostaglandin E2 (PGE2) release. RESULTS EECTD (300mg/kg) significantly reduced the number of writhing, extended the pain response latency, and suppressed xylene-induced ear swelling. Each EECTD treatment group also had significant inhibition of cotton granulation formation in addition to reduced carrageenan-induced paw edema. EECTD was also shown to alleviate signs of inflammation in histopathological paw sections. However, it had a less noticeable effect on mouse ear swelling in the delayed type hypersensitivity test. A purified compound was isolated from EECTD and its structure was identified as AA. In vitro experimental results showed that both EECTD and AA were able to significantly inhibit the release of pro-inflammatory cytokines NO and PGE2 on LPS-induced RAW264.7 cells. CONCLUSION These results suggest that EECTD has significant anti-inflammatory and antinociceptive activities, partially related to one of the active substances identified as AA. We hypothesize that these effects are related to its ability to inhibit the production of cytokines NO and PGE2. However, further work will be needed to determine its exact mechanism of action.

Abstract
Mycotic aneurysm of the superior mesenteric artery (SMA) is a rare complication of infective endocarditis. We report a case with infective endocarditis involving the aortic valve complicated by multiple septic embolisms. The patient was treated with antibiotics for 6 weeks. During preparation for surgical treatment, the patient developed acute abdominal pain and was diagnosed with a ruptured SMA aneurysm, which was successfully treated with an emergency operation of aneurysm ligation. The aortic valve was replaced 17 days later and the patient recovered uneventfully. In conclusion, we present a rare case with infective endocarditis (IE) complicated by SMA aneurysm. Antibiotic treatment did not prevent the rupture of SMA aneurysm. Abdominal pain in a patient with a recent history of IE should be excluded with ruptured aneurysm.

Abstract
Background The lung is one of the most common sites for extrahepatic metastasis from hepatocellular carcinoma (HCC). This study aimed to assess the efficacy of surgical resection for pulmonary metastases from HCC. Material/Methods The medical records of 9 patients who underwent pulmonary metastasectomy from HCC at 2 institutions were retrospectively studied, together with a review of studies reporting the outcomes of at least 5 patients in the Chinese and English languages. Results There were no perioperative deaths or major complications. The 1-, 3-, and 5-year overall survival rate after surgery was 100%, 44.4%, and 33.3%, respectively. A total of 19 studies involving 443 patients who underwent pulmonary metastasectomy for metastasis of HCC were included in the literature review. The median mortality rate was 0% (range, 0–7.1%). The median survival ranged from 10.7 to 77 (median=33.2) months, and the 5-year overall survival rate ranged from 11.5% to 75% (median=36%). Conclusions Surgical resection is a safe and effective treatment in selected patients with pulmonary metastases from HCC.

Abstract
BACKGROUND Surgical reconstruction following pancreaticoduodenectomy (PD) is associated with significant morbidity and mortality. Because of great variability in definitions of specific complications, it remains unclear whether there is a difference in complication rates following the two commonest types of reconstruction, pancreaticogastrostomy (PG) and pancreaticojejunostomy (PJ). Published consensus definitions for postoperative pancreatic fistula (POPF) have led to a series of randomized clinical trials (RCTs) uniquely placed to address this question. METHODS A literature search was carried out to identify all RCTs comparing postoperative complications of PG versus PJ reconstruction following PD published between January 1995 and December 2013. Pooled odds ratios (ORs) with 95 percent confidence intervals (c.i.) were calculated using fixed-effect or random-effects models. RESULTS In total, seven RCTs with 1121 patients were included. Four of these trials applied definitions as published by the International Study Group on Pancreatic Fistula (ISGPF). Using ISGPF definitions, the incidence of POPF was lower in patients undergoing PG than in those having PJ (OR 0·50, 95 per cent c.i. 0·34 to 0·73; P < 0·001). Using definitions applied by each individual study, PG was associated with significantly lower rates of POPF (OR 0·51, 0·36 to 0·71; P < 0·001), intra-abdominal fluid collection (OR 0·50, 0·34 to 0·74; P < 0·001) and biliary fistula (OR 0·42, 0·18 to 0·93; P = 0·03) than PJ. CONCLUSION Meta-analysis of four RCTs based on ISGPF criteria, and seven RCTs using non-standard criteria, revealed that PG reduced the incidence of POPF after PD compared with PJ.

Abstract
Cassava brown leaf spot surveys were conducted in the main cassava plantation areas of China between 2007 and 2012 in order to understand the distribution of the disease. Cassava plants were damaged by the disease to different degrees in most of the survey sites. Samples were collected and seven strains were isolated from lesions. The mycelium-breaking plus black light induction method was applied for sporulation. Microconidia were formed by means of fragmentation on artificial medium plates. When the leaf was stabbed and inoculated with conidia solution, similar symptoms were formed 14 days later. Morphological characteristics of the specimens and conidia were similar to descriptions of Passalora henningsii infection. The internal transcribed spacer (ITS) regions of rDNA were obtained with primer pair ITS1/ITS4 and deposited in GenBank, which differed by three base pairs from that of the P. henningsii isolate (AF284389). The ITS sequences of related species were downloaded from the NCBI database, and phylogenetic analysis showed that the sequences originating from our strains clustered in the same clade as the AF284389 isolate. Biological characteristics were evaluated in two strains from different sites, which indicated that the optimum conditions for mycelia growth were a temperature of 26° to 28°C, carrot agar medium, pH 6, and continuous dark; cassava leaf juice added to malt extract and cassava leaf juice added to potato dextrose agar were the best media for conidia production. The optimal and lethal temperatures for macroconidia germination were 26° to 28°C, and 60°C for 10 min, respectively.

Abstract
BACKGROUND The aim of this study was to evaluate the safety and efficacy of distal pancreatectomy with en bloc celiac axis resection (DP-CAR) for pancreatic body-tail cancer. MATERIAL AND METHODS The medical records of 12 patients who underwent DP-CAR for pancreatic body-tail cancer were retrospectively studied, together with a literature review of studies including at least 3 cases of DP-CAR. RESULTS There were no deaths among our 12 cases. Postoperative morbidity developed in 9 cases and was successfully managed by non-surgical treatment. No patients developed ischemic complications. Median overall survival was 10 months. A total of 19 studies involving 203 patients who underwent DP-CAR were included in the literature review. The overall morbidity and mortality rates were 50.2% and 3.0%, respectively. The overall median survival after surgery ranged from 9.3 to 26 months. CONCLUSIONS DP-CAR is a safe and effective treatment for patients with locally advanced pancreatic body-tail cancer.

Abstract
The AIM2 (absent in melanoma 2) protein promotes host defenses against invading viruses and pathogenic bacteria through corresponding adapter molecules leading to the initiation of innate immune responses. We investigated the expression of AIM2 in peripheral blood mononuclear cells (PBMCs) from patients with acute hepatitis B (AHB) and chronic hepatitis B (CHB) during different clinical phases, and analyzed the correlation between AIM2 and clinical profiles in these groups. This study indicated that there is higher expression of AIM2, IL-1β, and IL-18 in AHB compared with expression in CHB. The expression of AIM2 mRNA was significantly negatively correlated with serum hepatitis B virus (HBV) load, HBeAg, and significantly positively correlated with IL-1β and IL-18 in AHB patients and CHB patients with immune clearance, which suggests that AIM2 expression is correlated with the immune clearance of HBV in the host. We summarized that there is a higher immune status in AHB, and a lower immune response in CHB. This suggests that the down-regulation of AIM2 may be associated with the chronic development of HB.

Abstract
OBJECTIVE To observe the changes of blood viscosity and erythrocyte rheology in mice after acute hypoxic hypoxia (AHH). METHODS Thirty-two Kui-ming mice were randomly divided into control group, AHH group (duplicating AHH model, and divided into 5 min, 8 min, 11 min subgroups), the blood sample was taken out from heart after neck dislocation at corresponding times, for detecting the blood viscosity and erythrocyte rheology indices. RESULTS Compared with control group, the whole blood viscosity at different shears, whole blood reduced viscosity, whole blood relative viscosity were lower and the erythrocytes aggregation index was higher in AHH 5 min group; the electrophoresis time was longer and the electrophoresis length, migration of erythrocyte were lower in AHH 8 min and AHH 11 min groups. The whole blood reduced viscosity, whole blood relative viscosity, erythrocytes aggregation index in AHH 8 min group were higher, and the erythrocyte deformability index was lower significantly than that of AHH 5 min group, respectively. CONCLUSION These data suggested that the AHH could induce the blood viscosity and electrophoresis ability.

Abstract
This study explored the effect of the excitatory amino acid receptor antagonists on the impairment of learning-memory and the hyperphosphorylation of Tau protein induced by electroconvulsive shock (ECT) in depressed rats, in order to provide experimental evidence for the study on neuropsychological mechanisms improving learning and memory impairment and the clinical intervention treatment. The analysis of variance of factorial design set up two intervention factors which were the electroconvulsive shock (two level: no disposition; a course of ECT) and the excitatory amino acid receptor antagonists (three level: iv saline; iv NMDA receptor antagonist MK-801; iv AMPA receptor antagonist DNQX). Forty-eight adult Wistar-Kyoto (WKY) rats (an animal model for depressive behavior) were randomly divided into six experimental groups (n = 8 in each group): saline (iv 2 mL saline through the tail veins of WKY rats ); MK-801 (iv 2 mL 5 mg/kg MK-801 through the tail veins of WKY rats) ; DNQX (iv 2 mL 5 mg/kg DNQX through the tail veins of WKY rats ); saline + ECT (iv 2 mL saline through the tail veins of WKY rats and giving a course of ECT); MK-801 + ECT (iv 2 mL 5 mg/kg MK-801 through the tail veins of WKY rats and giving a course of ECT); DNQX + ECT (iv 2 mL 5 mg/kg DNQX through the tail veins of WKY rats and giving a course of ECT). The Morris water maze test started within 1 day after the finish of the course of ECT to evaluate learning and memory. The hippocampus was removed from rats within 1 day after the finish of Morris water maze test. The content of glutamate in the hippocampus of rats was detected by high performance liquid chromatography. The contents of Tau protein which included Tau5 (total Tau protein), p-PHF1(Ser396/404), p-AT8(Ser199/202) and p-12E8(Ser262) in the hippocampus of rats were detected by immunohistochemistry staining (SP) and Western blot. The results showed that ECT and the glutamate ionic receptor blockers (NMDA receptor antagonist MK-801 and AMPA receptor antagonist DNQX) induced the impairment of learning and memory in depressed rats with extended evasive latency time and shortened space exploration time. And the two factors presented a subtractive effect. ECT significantly up-regulated the content of glutamate in the hippocampus of depressed rats which were not affected by the glutamate ionic receptor blockers. ECT and the glutamate ionic receptor blockers did not affect the total Tau protein in the hippocampus of rats. ECT up-regulated the hyperphosphorylation of Tau protein in the hippocampus of depressed rats, while the glutamate ionic receptor blockers down-regulated it, and combination of the two factors presented a subtractive effect. Our results indicate that ECT up-regulates the content of glutamate in the hippocampus of depressed rats, which up-regulates the hyperphosphorylation of Tau protein resulting in the impairment of learning and memory in depressed rats.

Abstract
BACKGROUND Postoperative pancreatic leakage after pancreaticoduodenectomy is often serious. Although some studies have suggested that stenting the anastomosis can reduce the incidence of this complication, the value of stenting in the setting of pancreaticoduodenectomy remains unclear. METHODS Studies comparing outcomes of stent versus no stent, and internal versus external stent placement for pancreaticoduodenectomy were eligible for inclusion. Pooled odds ratios (ORs) with 95 per cent confidence intervals were calculated using fixed- or random-effects models. RESULTS From a search of the literature published between January 1973 and September 2011, five randomized clinical trials (RCTs) and 11 non-randomized observational clinical studies (OCS) involving 1726 patients were selected for inclusion in this review. Meta-analysis of RCTs revealed that placing a stent in the pancreatic duct did not reduce the incidence of postoperative pancreatic fistula. External stents had no advantage over internal stents in terms of clinical outcome. Subgroup analyses revealed that use of an external stent significantly reduced the incidence of pancreatic fistula (RCTs: OR 0·42, 0·24 to 0·76, P = 0·004; OCS: OR 0·43, 0·27 to 0·68, P < 0·001), delayed gastric emptying (RCTs: OR 0·41, 0·19 to 0·87, P = 0·02) and postoperative morbidity (RCTs: OR 0·55, 0·34 to 0·89, P = 0·02) compared with no stent. CONCLUSION Pancreatic duct stenting did not reduce the incidence of pancreatic fistula and other complications in pancreaticoduodenectomy compared with no stenting. Although no difference was found between external and internal stents in terms of efficacy, external stents seemed to reduce the incidence of pancreatic fistula compared with control.

Abstract
The phenomenon of vibrational resonance in a delayed multistable system that is excited by biharmonic signals is investigated in the present paper. Different from the former theory, the appearance and the disappearance of the vibrational resonance are controlled by adjusting the time delay parameter instead of modulating the amplitude of the high-frequency signal. The motion of the orbit within or between the different potential wells can also be controlled. Furthermore, based on both the methods of numerical simulation and analytical analysis, the behavior of delay-induced multiple vibrational resonance and its mechanism are investigated and discussed. The multiple vibrational resonance, which is quantified by the response amplitude at the low-frequency, is found to be periodic in the delay parameter with two periods, i.e., the periods of the two driven signals. The method used in this paper gives a new way for controlling vibrational resonance in a multistable system.

Abstract
In this study, we aimed to investigate the significance of hepatic stellate cells (HSCs) activation in small-for-size fatty liver graft injury and to explore the underlying molecular mechanism in a rat liver transplantation model. A rat orthotopic liver transplantation model using fatty grafts (40% of fatty changes) and cirrhotic recipients was applied. Intragraft gene expression profiles, ultrastructure features and HSCs activation were compared among the rats received different types of grafts (whole vs. small-for-size, normal vs. fatty). The distinct molecular signature of small-for-size fatty graft injury was identified by cDNA microarray screening and confirmed by RT-PCR detection. In vitro functional studies were further conducted to investigate the direct effect of specific molecular signature on HSCs activation. HSCs activation was predominantly present in small-for-size fatty grafts during the first 2 weeks after transplantation, and was strongly correlated with progressive hepatic sinusoidal damage and significant upregulation of intragraft Wnt4 signaling pathway. In vitro suppression of Wnt4 expression could inhibit HSC activation directly. In conclusion, upregulation of Wnt4 signaling led to direct HSC activation and subsequently induced small-for-size fatty liver grafts injury. Discovery of this distinct mechanism may lay the foundation for prophylactic treatment for marginal graft injury in living donor liver transplantation.
