Abstract
OBJECTIVE The aim of this retrospective study was to evaluate whether radiofrequency ablation (RFA) combined percutaneous ethanol injection (PEI) in the management of hepatocellular carcinoma (HCC) improves treatment outcomes. PATIENTS AND METHODS We retrospectively included 66 HCC patients who received RFA or RFA plus PEI from February 2011 to January 2014 in Jingmen No. 1 People's Hospital. Moreover, 31 cases received RFA plus PEI as the experiment group and 35 subjects treated with RFA aloe as the control group. The overall survival and treatment related complications were compared between the two groups. RESULTS For RFA group, the 1-year, 2-year, and 3-year survival rate were 82.0%, 69.3%, and 30.7%, respectively, with the median survival time of 27.1 months. For RFA plus PEI group, the 1-year, 2-year, and 3-year survival rate were 97.1%, 73.9%, and 37.5%, respectively, with the median survival time of 33.6 months. The overall survival of the two groups was not statistical different with the hazard ratio of 1.48 (P > 0.05); three cases of treatment associated complications were found in RFA group with 1 abscess, 1 pleural effusion, and 1 portal vein thrombosis. Moreover, 2 cases of complication were recorded in RFA plus PEI group with 1 pleural effusion and 1 portal vein thrombosis. The complicated incidence rate was not statistical different between the two groups (P < 0.05). CONCLUSION The combination treatment of HCC was safe and had a slightly higher primary effectiveness rate than RFA alone.

Abstract
OBJECTIVE To study the oxidative damage of PM2.5 in human embryonic stem cells (EBf-H9 cells), and to provide a theoretical basis for revealing the adverse health effects of PM2.5 and the potential mechanisms, and also to provide a new alternative cell model for PM2.5 risk assessment. METHODS EBf-H9 cells were cultured with 0.00 (the constrast group) 3.91, 7.81, 15.63, 31.25, 62.50, 125.00 μg/cm(2) of PM2.5. CCK-8 kit was used to determine the survival rate of cells exposed to PM2.5 for 6 h. DCFH-DA probe was used to detect the total ROS content of cells exposed to PM2.5 for 1 h. The activities of total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px), and the content of lipid peroxides such as malondialdehyde (MDA) in cells exposed to PM2.5 for 6 h were detected by using the commercial kits. ANOVA model analyzed the statistical significance from the different concentration group. RESULTS The cytotoxicity results showed that the cell survival rate was decreased gradually with the increase of the concentrations of PM2.5, and the half inhibitory concentration (IC50) was 83.01 μg/cm(2). When the exposure concentration was 3.91, 7.81, 15.63, 31.25, 62.5 μg/cm(2), after exposure of PM2.5 1 h, the ROS florescence was 27.12±0.21, 54.03±0.50, 60.93±0.08, 61.36±1.00, 68.21±0.93, 78.27±1.26 (compared to control group 27.12±0.21, all P level<0.01). After exposure of PM2.5 6 h, the activities of T-SOD was (9.78±0.28), (8.59±0.22), (8.90±0.33), (7.46±0.71), (4.21±0.17) U/mg protein (F=98.881, compared to control group (11.77±0.63) U/mg protein, all P level<0.01). The activities of GSH-Px was (181.59±3.65), (153.33±1.69), (168.74±2.22), (81.56±0.56), (48.62±2.13) U/mg protein (compared to control group (273.90±6.50) mU/mg protein, all P level<0.01). And the content of MDA was (0.38±0.03), (0.43±0.09), (0.47±0.09), (0.65±0.10), (0.70±0.12) nmol/mg protein (compared to control group (0.27±0.02) nmol/mg protein, all P level<0.05). CONCLUSION PM2.5 exposure can decrease EBf-H9 cells viability, and improve the levels of lipid peroxidation. It may be due to induce EBf-H9 cells to increase the production of ROS and to make the cells appear oxidative stress, which lead to oxidative damage to cells. The present study reveals the mode of action of PM2.5 in terms of oxidative damage to EBf-H9 cells. It is also indicated that the cells may be a new alternative cell model for PM2.5 risk assessment.

Abstract
The aim of the present study was to evaluate the efficacy of a herpes simplex virus type 2 (HSV-2) DNA vaccine co‑immunized with a plasmid adjuvant containing CpG motifs. A novel eukaryotic expression plasmid vector containing kanamycin resistance gene (pcDNA3Kan) was acquired from pET‑28a(+) and pcDNA3 plasmids. A gene encoding full length HSV‑2 glycoprotein D (gD) was amplified from the pcDNA3‑gD plasmid, which was cloned into pcDNA3Kan resulting in the construction of the recombinant plasmid pcDNA3Kan‑gD (pgD). A DNA segment containing 8 CpG motifs was synthesized, and cloned into pcDNA3Kan, resulting in the recombinant plasmid pcDNA3Kan‑CpG (pCpG). Mice were co‑inoculated with pgD (used as a DNA vaccine) and pCpG (used as an adjuvant) by bilateral intramuscular injection. Mice inoculated with pgD+pCpG showed higher titers of antibodies than those inoculated with the DNA vaccine alone (P<0.05). In addition, mice inoculated with pgD+pCpG showed the highest percentage of CD4+ T cells in the blood of all the groups (P﹤0.05). Thus, the present study demonstrated that pCpG could stimulate the HSV‑2 DNA vaccine to induce a stronger cell‑mediated immune response than the DNA vaccine alone. The aim of the present study was to evaluate the efficacy of a HSV‑2 DNA vaccine (pgD) co‑immunized with a plasmid adjuvant containing CpG motifs (pCpG). Whether the pCpG would be able to stimulate the pgD to induce a stronger immune response compared with pgD alone.

Abstract
Programmed cell death-1 (PD-1) is a member of the CD28 superfamily that delivers negative signals on interaction with its 2 ligands, PD-L1 and PD-L2. We assessed the contribution of the PD-1 pathway to regulating the polarization of macrophages that promote inflammation induced by zymosan. We found that PD-1−/− mice developed robust peritonitis with more abundant infiltration of M1 macrophages, accompanied by higher levels of pro-inflammation factors, especially monocyte chemotactic protein-1 (MCP-1) compared with wild-type controls ex vivo and in vitro. Our results indicated that PD-1 deficiency promotes M1 rather than M2 polarization of macrophages by enhancing the expression of p-STAT1/p-NF-κB p65 and downregulating p-STAT6. We found that PD-1 engagement followed by zymosan stimulation might primarily attenuate the phosphorylation of tyrosine residue in PD-1 receptor/ligand and the recruitment of SHP-2 to PD-1 receptor/ligand, leading to the reduction of M1 type cytokine production.

Abstract
This study aims to study impact of Dicliptera chinensis polysaccharide (DCP) on hepatic fibrosis (HF) and activation of hepatic stellate cells (HSCs). Liver fibrosis model was induced by intraperitoneal injection of dimethyl nitrosamines (DMN) in rat. Rats in treatment group were administrated with different concentrations of DCP (0, 100, 300 mg/kg) by intraperitoneal injection. Hematoxylin and eosin (H&E) and Masson's trichrome staining were used to assess histo-pathological change. α-SMA, TGF-β1 and pSmad 2/3 were assayed by immuno-histochemistry. HSC-T6 cells were stimulated by recombined rat TGF-β1 (1 ng/mL) to simulate an activating model in vitro and then interfered with DCP (concentration of 0, 25, 50, 100, 200, 400 µg/ml). MTT assay was used to determine cell proliferation and western blotting was used to detect α-SMA and pSmad 2/3 expression. Results demonstrated that DCP alleviated DMN-induced liver fibrosis in rat and significantly down-regulated TGF-β1 expression, pSmad2/3 and α-SMA in liver tissue in a dose-dependent way. DCP inhibited proliferation and activation of TGF-β1-stimulated HSC-T6 in vitro and significantly down-regulated α-SMA and pSmad2/3 expression. In conclusion, this study revealed that DCP attenuates progression of liver fibrosis through suppressing TGF-β/Smad pathway. DCP is a potential botanical polysaccharide to management liver fibrosis.

Abstract
Chemotherapy paclitaxel yields significant reductions in tumor burden in the majority of advanced non-small cell lung cancer (NSCLC) patients. However, acquired resistance limits its clinical use. Here we demonstrated that the histone deacetylase (HDAC) was activated in paclitaxel-resistant NSCLC cells, and its activation promoted proliferation and tumorigenesis of paclitaxel-resistant NSCLC cells in vitro and in vivo. By contrast, knockdown of HDAC1, a primary isoform of HDAC, sensitized resistant cells to paclitaxel in vitro. Furthermore, we observed that overexpression of HDAC1 was associated with the downregulation of p21, a known HDAC target, in advanced NSCLC patients with paclitaxel treatment, and predicted chemotherapy resistance and bad outcome. In addition, we also identified a novel HDACs inhibitor, SNOH-3, which inhibited HDAC expression and activity, induced cell apoptosis, and suppressed cell migration, invasion and angiogenesis. Notably, co-treatment with SNOH-3 and paclitaxel overcome paclitaxel resistance through inhibiting HDAC activity, leading to the induction of apoptosis and suppression of angiogenesis in vitro and in preclinical model. In summary, our data demonstrate a role of HDAC in paclitaxel-resistant NSCLC and provide a promising therapeutic strategy to overcome paclitaxel-acquired resistance.

Abstract
BACKGROUND AND PURPOSE Functional neuroimaging studies in irritable bowel syndrome have revealed abnormalities in the corticolimbic regions, specifically, hyperactivity of the amygdala during visceral and somatic stimulation. This study investigated changes in the neural circuitry of the amygdala in patients with irritable bowel syndrome based on resting-state functional connectivity. MATERIALS AND METHODS Functional MR imaging data were acquired from 31 patients with irritable bowel syndrome and 32 healthy controls (matched for age, sex, and educational level) during rest, and the resting-state functional connectivity of bilateral amygdalae was compared. Multiple regression was performed to investigate the relationship between clinical indices of patients with irritable bowel syndrome and resting-state functional connectivity. RESULTS Compared with healthy controls, patients with irritable bowel syndrome had higher positive resting-state functional connectivity between the amygdala and insula, midbrain, parahippocampal gyrus, pre- and postcentral gyri, and supplementary motor area. The inclusion of anxiety and depression as covariates did not alter amygdala resting-state functional connectivity differences between the study groups. Multiple covariate regression results showed that the pain intensity in patients with irritable bowel syndrome positively correlated with resting-state functional connectivity between the amygdala and supplementary motor area, pre- and postcentral gyri, and insula, while the Irritable Bowel Syndrome-Symptom Severity Score positively correlated with resting-state functional connectivity between the amygdala and insula and midbrain. CONCLUSIONS Patients with irritable bowel syndrome showed disturbed amygdala resting-state functional connectivity with the corticolimbic regions, which could partly account for the enhanced emotional arousal and visceral information processing associated with irritable bowel syndrome.

Abstract
BACKGROUND Few studies have explored the risk factors of sarcopenia in certain cohorts. The objective of this study was to examine the incidence of sarcopenia and associated factors over a 1-year period in an elderly Chinese suburban population. METHODS This study was conducted on 356 Chinese suburb-dwelling participants aged ≥60 years, for whom detailed information regarding sociodemographics, behavioral characteristics, and medical conditions had been documented. Sarcopenia was defined according to the Asian Working Group for Sarcopenia (AWGS) criteria. Sarcopenia incidence was documented after one year of follow-up, and correlated with several possible factors. RESULTS At baseline, 64 (9.7%) of the initial 657 participants had sarcopenia. The prevalence of sarcopenia was 10.4% after one year. Between baseline and 1-year follow-up, 13 of the participants without sarcopenia at baseline had developed sarcopenia. After multivariate adjustments, it was found that the incidence of sarcopenia increased with age and high body mass index (BMI) is associated with less incidence of sarcopenia. Incidence was also higher among women. CONCLUSIONS We found sarcopenia incidence increased with age, and women were more likely to have sarcopenia. A higher BMI is also associated with a lower incidence of sarcopenia. Maintaining a healthy weight could be beneficial in the prevention of sarcopenia.

Abstract
Combination of silica component with other materials is one of the current strategies to design bone regenerative materials. In this study, novel reduced graphene oxide (RGO)-aminosilica hybrid nanosheets with enhanced osteo-compatibility were synthesized from a mixture of 3-aminopropyltriethoxysilane (APTES), graphene oxides (GO) and water. The presence of APTES in the mixture not only caused the conversion of GO to RGO, but also led to the hydrolysis and condensation of itself. It was for the first time reported the reducing role of APTES in the conversion of GO to RGO. It was found that the silicon (IV) ions were released from the hybrid nanosheets in a sustained way. The in vitro osteo-compatibility was evaluated by incubating the hybrid nanosheets with osteoblast MC3T3-E1 cells. A water soluble tetrazolium salt assay quantitatively indicated that the hybrid nanosheets had no significant toxicity and exhibited good biocompatibility. An alkaline phosphatase assay quantitatively indicated that the hybrid nanosheets enhanced the osteoblast differentiation compared to the GO nanosheets. An immunochemical assay further qualitatively indicated that the hybrid nanosheets stimulated the production of osteopontin as typical marker for osteoblast differentiation. Thus, the resultant hybrids nanosheets had a potential application in the bone regeneration.

Abstract
In liver cirrhosis with bacterial infection, hepatoadrenal syndrome has been described recently as a progressive impairment in the adrenocortical reserve, with deficient production or action of glucocorticoids resulting in adrenal insufficiency. The aim of this study was to explore the characteristics of cortisol in hepatitis B virus (HBV) cirrhosis patients in the absence of bacterial infection. Fasting peripheral venous blood samples were collected from 107 patients with HBV cirrhosis in the absence of bacterial infection and 18 patients with chronic hepatitis B (CHB) infection at 7 a.m. in the morning. The carbohydrate, cortisol-binding globulin, routine chemistry, liver function, and hepatitis B indicators were tested, and free cortisol was calculated. Cortisol (COR) levels were 18.72 ± 6.60 μg/dL in the CHB group and 14.20 ± 7.55 μg/dL in the HBV cirrhosis group (P = 0.002). COR levels were 15.11 ± 5.56, 14.88 ± 6.96, and 12.68 ± 8.36 μg/dL in Child-Pugh class A, B, and C cirrhotic patients, respectively (P = 0.006). Adrenocorticotropic hormone levels were 35.42 ± 24.49, 26.57 ± 15.72, and 19.65 ± 10.72 pg/mL in Child-Pugh class A, B, and C cirrhotic patients, respectively (P = 0.000). Patients with HBV cirrhosis had significantly lower serum COR levels compared with those of CHB patients, even if they are in the absence of bacterial infection. COR levels negatively correlated with Child-Pugh scores. The hypothalamic-pituitary-adrenal axis might be damaged in patients with HBV cirrhosis.

Abstract
This study introduces the application of a new femoral distractor in the treatment of femoral fracture restoration with internal fixation of intramedullary nail. Sixty-three patients with femoral fracture from the Affiliated Hospital of Binzhou Medical University underwent femoral facture restoration with the new femoral distractor in combination with internal fixation of an intramedullary nail from June 2011 to March 2014. There were 18 cases of proximal femur fractures, 44 cases of middle femoral shaft fractures and 1 case of distal femur fracture. Follow-up was on the 4th, 6th, 8th, 12th, 16th and 24th week after operation. All 63 patients successfully underwent the surgery and the steel needles used did not cause injury to the adjacent vessels or nerves. Five cases had to have steel needles reinserted, as they had failed in the distraction reduction due to being unsteadily fixed because of an improper position. Patients were followed up for 10~24 months (mean 16 months), and the total healing rate was 100%. Operative time was 93.5 minutes averagely. Average time of patients exposure to X-ray was 26.8 seconds. Bleeding volume was averagely 219.1 ml. There were no complications either during the operations or after them. All cases healed within 12 weeks (average 7.6 weeks). This study proves that, the new femoral distractor can help the closed reduction of fractures in treating femoral fractures with intramedullary nails to avoid the inconvenience of applying traction tables and the occurrence of potential complications.

Abstract
A total of 48 carcasses of crossbred Hanzhong White pigs were divided into 3 groups (I, 90-99 kg; II, 100-109 kg; III, 110-119 kg) to investigate the influence of carcass weight on meat quality. The intramuscular fat content of the 3 groups increased from 1.90 to 4.90%; for meat color, Warner-Bratzler shear force, drip loss, and oxidation-type muscle fiber percentage, and muscle fiber diameter of the longissimus lumborum, the indices in group II and group III were better than those in group I (P < 0.05). The saturated fatty acid and polyunsaturated fatty acid percentages of the longissimus lumborum muscle (2.80 and 37.30%, respectively) in group II were significantly lower than those in the other 2 groups, while the monounsaturated fatty acid percentage was the highest (59.10%). In conclusion, our results suggest that a carcass weight of 100-109 kg is sufficient to produce acceptable meat quality of Hanzhong White pigs.

Abstract
OBJECTIVE To measure vertical axis length of humerus head in patients with proximal humeral fractures and to evaluate the use of structure screws in proximal humerus internal locking osteosynthesis system (PHILOS). METHODS From January 2007 to February 2014,117 patients with proximal humerus fracture were treated by PHILOS plate. Preoperatively, all the patients tookanteroposterior X-ray of shoulder, and the vertical axis length of humerus head were measured, and the use of structure screws in PHILOS plate was observed. RESULTS There were 40 male and 77 female patients; The vertical axis length of humerus head in male patients was (47.64±3.44) mm, and the rate of structure screw use was 52.5%; The vertical axis length of humerus head in female patients was (42.46±3.21) mm, and the rate of structure screw use was 32.5%. The vertical axis length of humerus head and the rate of structure screw use had significant difference in the male and female groups (P<0.05). CONCLUSION The rate of structure screw use was low in the treatment of proximal humerus fracture by PHILOS plate, especially for women. We should improve the design of plate according to the anatomical characteristics of Chinese.
