Abstract
PURPOSE To observe psychological conditions such as anxiety, depression and somatic symptoms of temporomandibular disorders(TMD) patients using psychological scales recommended by DC/TMD and evaluate their clinical significance as the psychological axis for TMD diagnosis. METHODS The experimental group included 100 TMD patients, and the control group comprised 100 normal prosthodontics outpatients without TMD symptoms. General information were collected including age, gender, education level, and personal income. The anxiety disorder scale (Generalized Anxiety Disorder-7, GAD-7), depression symptom scale (Patient Health Questionnaire-9, PHQ-9) and Patient Health Questionnaire-15 (PHQ-15) were used to evaluate patients' psychological conditions. SPSS 20.0 software package was used for data analysis. RESULTS Patients less than 30 years old and between 30-50 years had similar TMD occurrence rates, both significantly higher than those older than 50 years old(P<0.05). The proportion of highly educated patients in TMD group was significantly higher than that in the control group(P<0.05), while the income level was not a risk factor for TMD (P=0.642). The incidence and average scores of anxiety, not the depression or somatic symptoms, in experimental group were significantly higher than the control group(P<0.05). The level of anxiety and depression in painful TMD patients was significantly higher than patients with joint disease(P>0.05). CONCLUSIONS Gender(female), age (<50 years old) and high education level (undergraduate and above) are risk factors of TMD, but the income level is irrelevant. The incidence and scores of anxiety in TMD patients are higher than normal prosthodontics outpatients, while there is no significant difference in the incidence of depression and somatic symptoms between two groups.

Abstract
OBJECTIVE Conservative treatment modalities are recommended for managing masticatory myalgia in individuals with temporomandibular disorders. The aim of this study was to retrospectively review and compare the effectiveness of four conservative treatments: counseling and occlusal splint therapy, counseling and manipulation integrated with electrophysiotherapy, the combination of the two treatments, and counseling only. METHOD AND MATERIALS One hundred and sixty-eight patients who had myalgia with limited jaw movement were retrospectively observed in this study. Between January 2015 and December 2017, 63 patients received counseling and stabilization occlusal splint therapy (Group 1), 35 patients received counseling and manipulation integrated with electrophysiotherapy (Group 2), 33 patients received the combination of counseling, splint therapy, and manipulation integrated with electrophysiotherapy (Group 3), and 37 patients received counseling only (Group 4). All subjects were followed up for 12 weeks. The intensity of spontaneous pain, palpation pain, chewing pain in the masticatory muscles, and range of pain-free maximal mouth opening were recorded in the clinical assessments. Intragroup and intergroup differences were examined by using analysis of variance (ANOVA) and the Kruskal-Wallis test. RESULTS Spontaneous pain in the masticatory muscles was relieved significantly in all groups at the 6-week visit (P < .05), and no significant difference was found among the groups (P > .05). Palpation pain was relieved significantly at the 9-week visit in the counseling + occlusal splint therapy group, counseling + manipulation + electrophysiotherapy group, and counseling + occlusal splint + manipulation + electrophysiotherapy group (P < .05). In the treatment group with counseling alone, significant palpation pain relief occurred at 12 weeks. Chewing pain was relieved significantly at the 6-week visit in the counseling + occlusal splint therapy group, counseling + manipulation + electrophysiotherapy group, and counseling + occlusal splint + manipulation + electrophysiotherapy group (P < .05), yet no significant difference compared to the baseline was observed in the counseling-only group (P > .05). A significant increase in the maximal range of pain-free mouth opening was observed at the 9-week visit in the counseling + occlusal splint therapy group, and at the 3-week visit in the counseling + manipulation + electrophysiotherapy group and counseling + occlusal splint + manipulation + electrophysiotherapy group (P < .05). Nevertheless, no significant change in the range of mouth opening was found throughout the follow-up period in the counseling-only group (P > .05). CONCLUSION Each of the included treatment modalities relieved spontaneous pain and tenderness to palpation of the masticatory muscles during the follow-up intervals. Counseling alone did not help patients with chewing pain and limited mouth opening in the short term. Treatment protocols including counseling, occlusal splint therapy, and manipulation, integrated with electrophysiotherapy showed the best short-term outcomes for symptomatic improvement.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest solid tumors. Identification of diagnostic and therapeutic biomarkers for PDAC is urgently needed. Transducin (β)-like 1 X-linked receptor 1 (TBL1XR1) has been linked to the progression of various human cancers. Nevertheless, the function and role of TBL1XR1 in pancreatic cancers are unclear.
AIM To elucidate the function and potential mechanism of TBL1XR1 in the development of PDAC.
METHODS Ninety patients with histologically-confirmed PDAC were included in this study. PDAC tumor samples and cell lines were used to determine the expression of TBL1XR1. CCK-8 assays and colony formation assays were carried out to assess PDAC cell viability. Flow cytometry was performed to measure the changes in the cell cycle and cell apoptosis. Changes in related protein expression were measured by western blot analysis. Animal analysis was conducted to confirm the impact of TBL1XR1 in vivo.
RESULTS Patients with TBL1XR1-positive tumors had worse overall survival than those with TBL1XR1-negative tumors. Moreover, we found that TBL1XR1 strongly promoted PDAC cell proliferation and inhibited PDAC cell apoptosis. Moreover, knockdown of TBL1XR1 induced G0/G1 phase arrest. In vivo animal studies confirmed that TBL1XR1 accelerated tumor cell growth. The results of western blot analysis showed that TBL1XR1 might play a key role in regulating PDAC cell proliferation and apoptosis via the PI3K/AKT pathway.
CONCLUSION TBL1XR1 promoted PDAC cell progression and might be an effective diagnostic and therapeutic marker for pancreatic cancer.

Abstract
Objective: To investigate the effect of long-chain non-coding RNA Fez family zinc finger protein 1 antisense RNA1 (lncRNA FEZF1-AS1) on the biological function of hepatocellular carcinoma (HCC). Methods: SMMC771 and BEL-7402 cells were transfected with sh-FEZF1-AS1 and OE-FEZF1-AS1, respectively. The expression of lncRNA FEZF1-AS1 was detected by real-time quantitative PCR. Cell proliferation was detected by Cell Counting Kit-8 (CCK-8), and apoptosis was detected by flow cytometry. The effects of lncRNA FEZF1-AS1 on invasion and migration were detected by Transwell and wound healing assays. The expression levels of adhesion molecules were detected by Western blot. The effect of lncRNA FEZF1-AS1 on the in vivo growth was verified by nude mice xenograft experiments. Results: The silencing or ectopic expression of lncRNA FEZF1-AS1 inhibited or promoted the proliferation of hepatocellular carcinoma cells. CCK-8 assay showed that the proliferation abilities of SMMC7721 and BEL-7402 cells in sh-FEZF1-AS1 transfection group significantly decreased, achieving (35.43±4.06)% and (34.68±3.97)%, respectively, on the fifth day. There were significant differences between sh-FEZF1-AS1 group and sh-NC group [52.21±8.46)% and (53.76±7.64)%] (all P<0.05). In contrast, the proliferation ability of SMMC7721 and BEL-7402 cells transfected with OE-FEZF1-AS1 was significantly increased, achieving (83.49±6.92)% and (80.31±3.13)%, respectively, on the fifth day. There were significant differences between OE-FEZF1-AS1 and OE-NC group [53.03±8.84)% and (55.11±7.09)%] (all P<0.05). The subsequent flow cytometry results showed that cell apoptotic rates of SMMC7721 and BEL-7402 cells transfected with sh-FEZF1-AS1 were (13.02±1.38)% and (11.88±1.29)%, respectively, which were significantly higher than those in sh-NC groups [(5.57±1.46)% and (8.06±1.42)%, respectively, all P<0.05]. In contrast, the apoptotic rates of SMMC7721 and BEL-7402 cells transfected with OE-FEZF1-AS1 were (3.01±0.39)% and (3.22±0.43)%, which were significantly lower than those in OE-NC groups [(6.68±0.96)% and (6.63±0.45)%, all P<0.05]. In addition, knockdown or overexpression of lncRNA FEZF1-AS1 expression inhibited or enhanced the migration and invasion abilities as well as the levels of adhesion molecules in hepatocellular carcinoma cells. After 30 days of feeding under the same conditions, the tumor volumes of sh-FEZF1-AS1 and sh-NC SMMC7721 cells xenograft mice models were (0.26±0.03) cm(3) and (0.63±0.06) cm(3), respectively, showing significant difference (P<0.05). The tumor volumes of sh-FEZF1-AS1 and sh-NC BEL-7402 cells were (0.31±0.02) cm(3) and (0.72±0.08) cm(3), and the difference was statistically significant (P<0.05). Conclusion: lncRNA FEZF1-AS1 may strengthen the growth, migration and invasion of hepatocellular carcinoma cells.

Abstract
Objective: To investigate the expression and clinical significance of KIAA1199 in primary hepatocellular carcinoma. Methods: A total of 136 cases of primary hepatocellular carcinoma tissues and paired adjacent tissues were collected. Immunohistochemistry and Western blot were used to detect the expression of KIAA1199 in primary hepatocellular carcinoma tissues and paired adjacent tissues. The relationship between KIAA1199 and clinicopathological parameter of primary hepatocellular carcinoma was analyzed. Results: The positive rate of KIAA1199 in primary hepatocellular carcinoma was 82.3% (112/136), which was higher than that in paired para-cancerous tissues (14.7%, 20/136). High expression of KIAA1199 was significantly correlated with age, cirrhosis history, tumor size, tumor number, degree of differentiation, TNM staging and microvenous invasion (MVI) (P<0.05), but without gender, drinking alcohol hobby, hepatitis history, family genetic history, tumor location (P>0.05). The Kaplan-Meier survival curves indicated that high KIAA1199 expression was associated with poor survival (P<0.01). In addition, Cox proportional hazards model showed that the expression of KIAA1199 was related to age, cirrhosis history, tumor size, tumor number, degree of differentiation, TNM staging and MVI (P<0.05). Conclusion: The expression of KIAA1199 is up-regulated in primary hepatocellular carcinoma, which is significantly correlated with the clinicopathological features and prognosis, high expression of KIAA1199 increased the risk of death in patients with primary hepatocellular carcinoma.

Abstract
OBJECTIVE There is little evidence that adjuvant therapy after radical surgical resection of hepatocellular carcinoma (HCC) improves recurrence-free survival (RFS) or overall survival (OS). We conducted a multicentre, randomised, controlled, phase IV trial evaluating the benefit of an aqueous extract of Trametes robinophila Murr (Huaier granule) to address this unmet need. DESIGN AND RESULTS A total of 1044 patients were randomised in 2:1 ratio to receive either Huaier or no further treatment (controls) for a maximum of 96 weeks. The primary endpoint was RFS. Secondary endpoints included OS and tumour extrahepatic recurrence rate (ERR). The Huaier (n=686) and control groups (n=316) had a mean RFS of 75.5 weeks and 68.5 weeks, respectively (HR 0.67; 95% CI 0.55 to 0.81). The difference in the RFS rate between Huaier and control groups was 62.39% and 49.05% (95% CI 6.74 to 19.94; p=0.0001); this led to an OS rate in the Huaier and control groups of 95.19% and 91.46%, respectively (95% CI 0.26 to 7.21; p=0.0207). The tumour ERR between Huaier and control groups was 8.60% and 13.61% (95% CI -12.59 to -2.50; p=0.0018), respectively. CONCLUSIONS This is the first nationwide multicentre study, involving 39 centres and 1044 patients, to prove the effectiveness of Huaier granule as adjuvant therapy for HCC after curative liver resection. It demonstrated a significant prolongation of RFS and reduced extrahepatic recurrence in Huaier group. TRIAL REGISTRATION NCT01770431; Post-results.

Abstract
To identify biologically relevant genes associated with the pathogenesis of colorectal cancer (CRC), genome wide expression profiles of 17 pairs of CRC tumor and adjacent tissues, previously published in a DNA microarray study, were analyzed. Cytoscape, String tools and DAVID tools were used to investigate the biological pathways encoded by the genes identified as being either upregulated or downregulated in CRC, to determine protein-protein interactions and to identify potential hub genes associated with CRC. As a result, a total of 3,264 genes were identified as being differentially expressed in CRC and adjacent tissues, including 1,594 downregulated and 1,670 upregulated genes. Furthermore, 306 genes were revealed to be clustered in a complex interaction network, and the top 20 hub genes in this network were determined by application of the Matthews Correlation Coefficient algorithm. In addition, the patterns of the expression levels of the 20 hub genes were investigated using reverse transcription-quantitative polymerase chain reaction. Gene Ontology analysis revealed that four of the 20 hub genes encoded small subunit processome components (UTP3 small subunit processome component; UTP14 small subunit processome component; UTP 18 small subunit processome component; and UTP20 small subunit processome component) and a further four encoded WD repeat domains (WD repeat-containing protein 3, WD repeat domain 12, WD repeat-containing protein 43 and WD repeat-containing protein 75). In conclusion, the present DNA microarray study identified genes involved in the pathogenesis of CRC. Furthermore, it was revealed that hub genes identified from among the total identified upregulated and downregulated genes in CRC encoding subunit processome components and WD repeat domains may represent novel target molecules for future treatments of CRC.

Abstract
Objective To investigate enteral nutrition’s effect on serum inflammatory factors and the cardiac function of malnourished elderly patients with heart failure. Patients and methods A total of 105 elderly patients with heart failure were randomly divided into 3 groups: Treatment Group A, Treatment Group B, and the Control Group (Group C), each group having 35 patients and being administered conventional heart failure treatment. Group A was treated with 500 mL·d−1 of enteral nutrition for 1 month. Group B was given the same dose of enteral nutrition for 3 months. The Control Group was given free diet. Nutritional risk screening 2002 was used to assess the nutritional status before and after the treatment for each group. New York Heart Association status was recorded as were left ventricular ejection fraction, plasma B-type natriuretic peptide, inteleukin-6, C-reactive protein, and tumor necrosis factor-α. Results After the treatment, the body mass index, skinfold thickness of upper arm triceps, muscle circumference of the upper arm, upper arm muscle circumference, total protein, albumin, hemoglobin, and left ventricular ejection fraction in the treatment groups all increased, with relatively obvious relief of symptoms of heart failure. The levels of B-type natriuretic peptide, interleukin-6, tumor necrosis factor-α, and C-reactive protein all rose to different extents (P<0.05) and Treatment Group B showed more obvious improvement (P<0.01). Differences shown by the Control Group in each nutrition indicator, serum levels of inflammatory factors, and cardiac function had no statistical significance (P>0.05). Conclusion The use of enteral nutrition in conventional treatment of elderly patients with heart failure could improve not only patients’ nutritional status and cardiac function, but also their immune function, thus reducing the levels of inflammatory factors. The longer the treatment period is, the more obvious the improvement in patients’ cardiac function and inflammatory factors will be observed.

Abstract
MicroRNAs (miRNAs) are short, non-coding RNA molecules that act as regulators of gene expression. Circulating blood miRNAs have potential as cancer biomarkers. The main objective of the present study was to assess the effect of miRNA-23b (miR-23b) expression in plasma on the diagnosis and prognosis of colorectal cancer (CRC). Reverse transcription-quantitative polymerase chain reaction (PCR) was used to measure miR-23b expression levels, and methylation-specific PCR was used to test the promoter methylation status. Subsequently, the expression level of miR-23b in plasma samples was compared between CRC patients and healthy control individuals. The miR-23b expression levels were significantly lower in CRC cells and primary CRC tissues than in nonmalignant colorectal tissues (P<0.001). It was also shown that miR-23b expression is downregulated by promoter methylation and can be restored by demethylation agent treatment. miR-23b was significantly decreased in plasma samples from CRC patients compared with the healthy control individuals (P<0.001). The value of the area under the receiver operating characteristic curve was 0.842 (sensitivity, 84.38%; specificity, 77.08%; 95% confidence interval, 0.763-0.922). Low plasma miR-23b expression was significantly associated with clinical stage, tumor depth, distant metastasis and tumor recurrence. CRC patients with low miR-23b expression in plasma exhibited a shorter recurrence-free survival time and poorer overall survival rate. The present results suggested that the downregulation of miR-23b in the plasma has the potential to be a diagnostic and prognostic biomarker in CRC.

Abstract
Ischemia/reperfusion (I/R) injury can occur during small-for-size liver transplantation, resulting in delayed graft function and decreased long-term graft survival. The aim of the present study was to evaluate the effects of genetic overexpression of endothelial nitric oxide synthase (eNOS) in protecting hepatocytes against I/R injury in a rat model of small-for-size liver transplantation. L02 liver cells were transfected with the eNOS gene using an adenovirus (Ad-eNOS). eNOS expression was detected using quantitative polymerase chain reaction and western blot analysis. To evaluate the effect of eNOS overexpression, L02 cells were placed in a hypoxic environment for 12 h and immediately transferred to an oxygen-enriched atmosphere. For in vivo testing, rats pretreated with Ad-eNOS or control underwent small-for-size liver transplantation. At 6 h after reperfusion, the bile quantity, serum transaminase and nitric oxide (NO) levels, and histological outcomes were evaluated. Cell apoptosis was assessed by flow cytometry or TUNEL assay. In vitro, Ad-eNOS prevented apoptosis in L02 cells with an increase in the level of NO in culture supernatant. In vivo, Ad-eNOS pre-treatment significantly increased bile production, improved abnormal transaminase levels, diminished apoptosis among liver cells, and decreased hepatocellular damage at 6 h after I/R injury. The eNOS-mediated renal protective effects might be associated with the downregulation of tumor necrosis factor-α and a reduction in macrophage activation in the early stage of reperfusion in small-for-size liver allografts. eNOS-derived NO production significantly attenuates hepatic I/R injury. Thus, eNOS overexpression constitutes a promising therapeutic approach to prevent liver I/R injury following small-for-size liver transplantation.

Abstract
The aim of this study was to identify key genes related to invasive ductal carcinoma (IDC) of the breast by analyzing gene expression data with bioinformatic tools. Microarray data set GSE31138 was downloaded from Gene Expression Omnibus, including 3 breast cancer tissue samples and 3 normal controls. Differentially expressed genes (DEGs) between breast cancer and normal control were screened out (FDR < 0.05 and |logFC| > 2). Coexpression between genes was examined with String, and a network was then constructed. Relevant pathways and diseases were retrieved with KOBAS. A total of 56 DEGs were obtained in the IDC of the breast compared with normal controls. A gene coexpression network including 27 pairs of genes was constructed and all the genes in the network were upregulated. Further study indicated that most of the genes in the coexpression network were enriched in ECM-receptor interaction (COL4A2, FN1, and HMMR) and nucleotide excision repair (CETN2 and PCNA) pathways, and that the most significantly related disease was autoimmune lymphoproliferative syndromes. A number of DEGs were acquired through comparative analysis of gene expression data. These findings are beneficial in promoting the understanding of the molecular mechanisms in breast cancer. More importantly, some key genes were revealed via gene coexpression network analysis, which could be potential biomarkers for IDC of the breast.

Abstract
AIM: To determine the influence of Adriamycin (ADM) on the changes in Nanog, Oct4, Sox2, as well as, in ARID1 and Wnt5b expression in liver cancer stem cells.
METHODS: The MHCC97-L and HCCLM3 liver cancer cell lines were selected as the cell models in this study, and were routinely cultured. The 50% lethal dose (LD50) in the cell lines was detected by the MTT assay. Expression changes in liver cancer stem cell related genes (Nanog, Oct-4, Sox2, ARID1, and Wnt5b) were detected by western blot following treatment with ADM (LD50).
RESULTS: The LD50 of ADM in MHCC97-L cells was lower than that in HCCLM3 cells (0.4123 ± 0.0236 μmol/L vs 0.5259 ± 0.0125 μmol/L, P < 0.05). Wnt5b and Nanog were expressed in both MHCC97-L and HCCLM3 cells, while only Sox2 was expressed in HCCLM3 cells. However, neither ARID1A nor Oct4 was detected in these two cell lines. Genes, related to the stem cells, showed different expression in liver cancer cells with different metastatic potential following treatment with ADM (LD50). Wnt5b protein increased gradually within 4 h of ADM (LD50) treatment, while Nanog decreased (P < 0.05). After 12 h, Wnt5b decreased gradually, while Nanog increased steadily (P < 0.05). In addition, only Sox2 was expressed in HCCLM3 cells with high metastatic potential following ADM (LD50) treatment. The expression of Sox2 increased gradually with ADM (LD50) in HCCLM3 cells (P < 0.05).
CONCLUSION: ADM increased the death rate of MHCC97-L and HCCLM3 cells, while the growth suppressive effect of ADM was higher in MHCC97-L cells than in HCCLM3 cells.

Abstract
AIM: To compare the clinical effects of regular versus irregular liver resection for malignant tumors of the liver.
METHODS: Clinical data for 120 patients who underwent liver resection for malignant tumors of the liver at our hospital from January 2010 to December 2012 were analyzed retrospectively.
RESULTS: The amount of bleeding, the incidence of complications and mortality, and the length of hospital stay showed no significant differences (all P > 0.05) between patients undergoing irregular liver resection and those undergoing regular liver resection. The operative time was significantly longer in the regular liver resection group than in the irregular liver resection group (221.8 min ± 101.7 min vs 211.3 min ± 102.6 min, P < 0.05).
CONCLUSION: The aesthetic effect of regular liver resection is better than that of irregular liver resection. For patients with small tumors, irregular liver resection is more simple and effective and can achieve radical results. For those patients with cirrhosis, regular liver resection has higher safety. Liver resection strategy should be selected based on the patient's condition to improve effectiveness and safety.

Abstract
OBJECTIVE In order to investigate whether the presence of distant metastases is associated with serum lipid abnormalities. METHODS The fasting serum lipid profile and various clinicopathological data of 324 breast cancer patients with and without synchronous distant metastases were collected and analyzed. The serum lipid profile, including total cholesterol (TC), triglycerides (TG), low-density (LDL-C) and high-density lipoprotein cholesterol (HDL-C) was determined. The nutritional status, the serum albumin was measured and body mass index (BMI) was calculated. Univariate analysis and multiple logistic regression analysis were carried out to investigate the association of serum lipid profile with distant metastases. RESULTS Univariate analysis showed that the distant metastasis rate was significantly higher in the breast cancer patients with an higher level of serum TC, TG, LDL-C, and LDL-C/HDL-C ratio (P < 0.05). Multiple logistic regression analysis showed that higher serum levels of TC, LDL-C and LDL-C/HDL-C ratio were independent risk factors for distant metastasis in breast cancer (OR = 2.324, 2.648 and 4.862, respectively). CONCLUSIONS Hyperlipidemia is significantly associated with the distant metastasis in breast cancer patients. Monitoring of serum lipid profile may be helpful to predict the occurrence of distant metastasis in breast cancer patients.

Abstract
AIM: To prepare galactose-carboxyl chitosan-myristic acid (GCCMA) nanoparticles and to obverse their targeting of hepatoma carcinoma cells (HCCs).
METHODS: GCCMA nanoparticles were prepared by self-assembled technology, and their stability and biocompatibility were assessed. After fluorescent labeling, GCCMA nanoparticles of different concentrations were transfected into HCCs and HT22 hippocampal neurons. Non-transfected HCCs and HT22 hippocampal neurons were used as controls. Based on the concentrations of GCCMA nanoparticles, HCCs transfected with GCCMA nanoparticles were divided into low-, medium- and high-concentration groups. The cellular uptake of nanoparticles was determined at 1, 2 and 4 h after transfection.
RESULTS: The cellular uptake of nanoparticles in the HCC group was much higher than that in the HT22 hippocampal neuron group. The uptake of nanoparticles in the HCC group was dose-dependent. The highest uptake of nanoparticles in the HCC group was observed at 4 hours after transfection.
CONCLUSION: GCCMA nanoparticles show hepatic targeting and are therefore a potential drug-carrier or administration route for chemotherapy drugs or targeted gene therapy for hepatic tumors.

Abstract
OBJECTIVE To investigate the association between the connexin 37 C1019T polymorphism and Helicobacter pylori infection in patients with gastric cancer. METHODS 388 patients with gastric cancer (GC), 204 with chronic superficial gastritis (CSG) were studied. H. pylori was detected by gastric mucosal biopsies biopsy dyeing method. Connexin 37 gene polymorphism 1019 site genotypes were determined by gene sequencing technology. Genotypes and alleles frequencies were compared. RESULTS (1) Connexin37 gene 1019 site distribution frequency (CC type, TC type, TT type) in the CSG group was 18.1%, 45.1% and 36.8%; in the stomach cancer group it was 35.1%, 45.9% and 19.%, conforming to the Hardy-Weinberg euilibrium. (2) In comparison with CSG group, the frequency of Connexin37 C allele was higher in the gastric cancer group (58.0% vs 40.7%, OR=2.01, 95%CI=1.58-2.57, P<0.01). The prevalence of gastric cancer risk was significantly increased in the carriers of C allele (CC+TC) than in TT homozygote (OR=2.47, 5%CI=1.68-3.610. (3) Gastric cancer patients complicated with Hp infection 211 cases, gastric cancer group of the male patients with HP positive patients with 187 cases, 40 cases of female patients with negative patients, 24 cases were HP positive, negative in 137 cases, control group male patients, 28 cases were Hp positive, negative in 95 patients, female patients with Hp positive 6 cases, 75 cases were negative. On hierarchical analysis, the male group OR value was 15.9 (95%CI to 9.22-27.3), and the female OR was 2.19 (95%CI 0.88-5.59), indicating a greater contribution in males (P<0.01). After elimination of gender effects, positive HP and gastric cancer were closely related (OR 8.82, 95% CI: 5.45-14.3). (4) The distribution frequency of C allele in patients with Hp infection was much higher than that in Hp negative cases in the GC group (64.5% vs 47.0%, OR=2.05, 95%CI=1.54-2.74, P<0.01). Compared with TT homozygotes, (CC+TC) genotype prevalence of gastric cancer risk increased significantly (OR=2.96, 5%CI=1.76-2.99). CONCLUSION The T allele in the connexin37 gene might not only be associated with gastric cancer but also with H. pylori infection.

Abstract
BACKGROUND/AIMS Although changes in serum lipid profile have been reported in CRC, the specific association between serum lipid profile and lymph node stages remains uncertain. METHODOLOGY Fasting serum lipid profile, including TC, TG, HDL-C and LDL-C was retrospectively evaluated in 968 patients undergoing curative resection for primary CRC. To determine the nutritional status, the serum albumin levels were measured and BMI was calculated. Statistical analyses were performed to investigate the association of serum lipid profile with lymph node stages. RESULTS Serum lipid levels correlated well with rate of lymph node metastasis and high LDL-C and low HDL-C levels tended to present more advanced lymph node stages. The observed elevation of the LDL-C/HDL-C ratio for patients with N2 stage was statistically significant when compared with patients with N1 stage. When separated by gender, multivariate logistic regression analysis showed that both LDL-C levels and LDL-C/HDL-C ratio had independent association with advanced N2 stage in males, but not in females. In addition, LDL-C/HDL-C ratio might be a more effective biomarker for identifying N2 stage than LDL-C levels alone (OR value: 2.85 vs. 1.63). CONCLUSIONS Elevated serum LDL-C levels and an increased LDC-C/HDL-C ratio might favour development of lymph node metastasis and LDCC/HDL-C ratio might be a more effective biomarker for identifying advanced N2 stage than LDL-C levels alone, especially for male patients with CRC.

Abstract
AIM: To study the effects of portal vein arterialization (PVA) on the liver regeneration in hepatocirrhosis after partial hepatectomy in dogs in order to provide a basis for its clinical use.
METHODS: The liver cirrhosis model of dogs was established. The dogs were divided into three groups randomly: group A (PVA group), partial hepatectomy plus PVA; group B (control group), partial hepatectomy; and group C, sham-operated group. All dogs were killed four weeks after operation. During the experiment, liver regeneration rate, expression of proliferating cell nuclear antigen (PCNA) in liver tissue and arterial ketone body ratio(AKBR) were observed.
RESULTS: Liver regeneration rate was significantly higher in group A than in group B (86.6% ± 2.9% vs 73.7% ± 6.9%, P < 0.01); the AKBR of groups A and B was significantly lower than group C (both P < 0.01), but 4 wks after operation , the AKBR of group A(1.32 ± 0.14) became close to group C (1.33±0.11), without significant difference (P > 0.05); the expression of PCNA in liver tissues of group A was significantly faster than group B.
CONCLUSION: PVA has significantly positive effect on liver regeneration after partial hepatectomy in dogs with hepatocirrhosis.

Abstract
BACKGROUND AND AIM The tumor-suppressing role of Ras-association domain family 1A (RASSF1A) has been described in several systems. In this study, we tested its tumor-suppressing ability and the potential molecular mechanisms in hepatocellular carcinoma (HCC) from Qidong County. METHODS Reverse transcription polymerase chain reaction and Northern blotting were employed to detect the expression of RASSF1A in HCC. After establishing stable RASSF1A (wild type or mutant) expressing 'qi dong gan ai yan jiu suo' ([Qidong Institute of Liver Cancer] QGY)-7703 cell lines, we tested the effects of RASSF1A expression on cell growth by cell proliferation rate, cell colony formation, and cell cycle progression. We also tested the effects of RASSF1A expression on tumorigenesis in nude mice and on cellular sensitivity to mitomycin treatment. RESULTS The RASSF1A transcript was not found in 75% (three of four) of HCC cell lines and 67% (32/48) of HCC primary biopsies. The stepwise regression analyses indicated that the loss of RASSF1A expression was more frequent in patients who were hepatitis B virus surface antigen positive (HBsAg+) compared to those who were HBsAg(-), both in tumor and corresponding non-cancerous tissues. The wild-type (wt)-RASSF1A expression in the QGY-7703 cell line resulted in fewer and smaller clones, decreased xenograft tumor volume and weight, and G(1)/S arrest in vitro and in vivo. The wt-RASSF1A expression also decreased the cyclin D1 protein expression, which appeared to be at the level of post-transcriptional control. In addition, the wt-RASSF1A expression increased cell growth inhibition and the percentage of cells with sub-G(1) DNA content when the cells were treated with mitomycin. CONCLUSION RASSF1A is a tumor suppressor in HCC. The loss of RASSF1A expression may be related to HBsAg+ in hepatocarcinogenesis. Its inactivation may play an important role in the development of HCC.

Abstract
PURPOSE To study the color distribution of the anterior teeth in elder people. METHODS 612 anterior teeth from 137 people aging from 60 to 81 years and 200 anterior teeth from 100 young people aging from 20 to 40 years were collected. A digital colorimeter was used to measure the value of L*,a*,b* of the teeth, and the chromatism (deltaE) was calculated according to the formula deltaE=(deltaL*(2)+deltaa*(2)+deltab*(2))1/2. All data were analyzed with SAS 6.12 software package for Student's t test. RESULTS Totally, there were 612 vital anterior teeth from elder people, including 201 central incisors,199 lateral incisors and 212 canines, were collected. No difference was found between the teeth on the right side and the left side in terms of L*,a*,b*value(P>0.05). The mean value of L*,a*,b* of the central incisors was 71.2+/-6.22,0.97+/-1.12,15.9+/-5.04, respectively and that of the lateral incisors and the canines were 69.6+/-5.52,0.6+/-1.18,13.9+/-4.15 and 68.4+/-5.99,0.15+/-1.02,19.6+/-4.87, respectively.The mean value of L*,a*,b* of the central incisors and the canines from the youngster was 75.82,-0.11,12.68 and 72.07,1.22,17.92, respectively.There were significant differences between the central incisors and the lateral incisors as well as the canines (P<0.05) in terms of L* value. Meanwhile difference was also found among the incisors and the canines in terms of a* and b* value(P<0.05). The deltaE between the central incisors and the lateral incisors was 2.945NBS, and the value between the canines and the central incisors as well as the lateral incisors was 4.629NBS and 5.832NBS, respectively, indicating that the color difference could be perceived visually. Compared to the youngster, the teeth of the elder people demonstrated a lower L* and a* value, but a higher b* value (P<0.05). CONCLUSIONS Among elder people, the central incisors look much brighter than the lateral incisors and canines, while the canines have more redness and yellowness than the incisors, and the color of the lateral incisors exhibits lighter than the central incisors and the canines. Compared to the teeth from younger people, the teeth from elder people look much darker and yellower but less red. Supported by Shanghai Leading Academic Discipline Project (Grant No.T0202).

Abstract
AIM: To investigate the role of the duodenum in the regulation of plasma ghrelin levels and body mass index (BMI), and the correlation between them after subtotal gastrectomy.
METHODS: Forty-two patients with T0-1N0-1M0 gastric cancer were divided into two groups after gastrectomy according to digestive reconstruction pattern, Billroth I group (n = 23) and Billroth II group (n = 19). Ghrelin levels were determined with radioimmunoassay (RIA) before and on d 1, 7, 30 and 360 after gastrectomy, and BMI was also measured.
RESULTS: The two groups had identical postoperative trends in ghrelin alterations during the early stage, both decreasing sharply to a nadir on d 1 (36.7% vs 35.7%), then markedly increasing on d 7 (51.0% vs 51.1%). On d 30, ghrelin levels in the Billroth I group were slightly higher than those in the Billroth II group. However, those of the Billroth I group recovered to 93.6% on d 360, which approached, although lower than, the preoperative levels, and no statistically significant difference was observed. Those of the Billroth II group recovered to only 81.6% and manifested significant discrepancy with preoperative levels (P = 0.033). Compared with preoperative levels, ghrelin levels of the two groups decreased by 6.9% and 18.4% and BMI fell by 3.3% and 6.4%, respectively. The linear regression correlations were revealed in both groups between decrease of ghrelin level and BMI (R12 = 0.297, P = 0.007; R22 = 0.559, P < 0.001).
CONCLUSION: Anatomically and physiologically, the duodenum compensatively promotes ghrelin recovery and accordingly enhances BMI after gastrectomy. Regarding patients with insufficient ghrelin secretion, ghrelin is positively associated with BMI.

Abstract
BACKGROUND & OBJECTIVE Using small interfering RNA (siRNA) to inhibit mammal gene expression becomes an effective technique in studying gene function. This study was to investigate the effect of insulin-like growth factor 1 receptor (IGF1R) siRNA on the growth of human liver cancer SMMC7721 cell xenograft in nude mice. METHODS siRNA targeting IGF1R was designed, and plasmid SMMC7721-IGF1R-siRNA was constructed and transfected into SMMC7721 cells (SMMC7721-IGF1R-siRNA cells); the cells transfected with SMMC7721-IGF1R-mutation (SMMC7721-IGF1R-mutation cells) were used as negative control, and untransfected cells as empty control. Stable cell clones were screened by G418, and transplanted into nude mice to establish cancer xenograft. Tumor growth was monitored. Tumor morphology was observed with HE staining. The expression of IGF1R protein in tumor tissues was detected by Western blot. Microvessel density (MVD) in tumor tissues was detected by SP immunohistochemistry. Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay. RESULTS The tumor volume was significantly smaller in SMMC7721-IGF1R-siRNA group than in SMMC7721-IGF1R-mutation group and SMMC7721 group (P < 0.05). Necrosis and cell apoptosis were found in SMMC7721-IGF1R-siRNA group. The expression of IGF1R protein was significantly lower in SMMC7721-IGF1R-siRNA group than in SMMC7721-IGF1R-mutation group and SMMC7721 group (P < 0.05). MVD was significantly lower in SMMC7721-IGF1R-siRNA group than in SMMC7721-IGF1R-mutation group and SMMC7721 group (11.3+/-4.4 vs. 36.7+/-7.6 and 28.4+/-6.5, P < 0.05). The apoptosis rate of tumor cells was significantly higher in SMMC7721-IGF1R-siRNA group than in SMMC7721-IGF1R-mutation group and SMMC7721 group [(50.2+/-6.4)% vs. (5.4+/-1.0)% or (6.0+/-2.1)%, P < 0.05]. CONCLUSION IGF1R siRNA can inhibit the growth of SMMC7721 cell xenograft in nude mice.

Abstract
The crystal structure of plakalbumin, a proteolytically nicked form of ovalbumin, has been determined to a resolution of 2.8 A by the isomorphous replacement method and preliminary refinement. The structure closely resembles that of the cleaved form of alpha-1-proteinase inhibitor, with some important exceptions. The disposition of the new carboxyl chain terminus liberated by proteolysis is different with respect to the central beta-sheet A in the structures of these two molecules. In alpha-1-proteinase inhibitor, the new chain terminus inserts in beta-sheet A to add a middle strand to the sheet. In plakalbumin, this strand remains free near the site at which the cleavage occurs. A structural basis for this difference in behavior is proposed from the structures and sequences of these two molecules and other members of the serpin family. The structures and positions of the putative signal peptide of ovalbumin, the several post-translational modifications, and the relationship of the intron-exon patterns of plakalbumin and alpha-1-proteinase inhibitor to their protein structures are also described.
