Abstract
Objectives: To investigate the associations of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) gene polymorphism and plasma soluble TRAIL level (sTRAIL) with Crohn's disease (CD) and to retrospectively analyze the effects of TRAIL gene variants and plasma sTRAIL levels on clinical response to infliximab (IFX). Methods: From January 2012 to January 2021, 312 CD patients [205 males, 107 females, average age (33.9±9.8) years] and 514 age-and gender-matched healthy controls [304 males, 210 females, average age (34.9±9.4) years] were recruited from the Department of Gastroenterology, the Second Affiliated Hospital of Wenzhou Medical University. Among them, 72 patients with active CD who were ineffective or intolerant to traditional drug therapy regularly received IFX (5 mg/kg) treatment. According to the changes in the Harvey-Bradshaw index (HBI) and the Simplified Endoscopic Score for Crohn's Disease (SES-CD) in the 14th week, these patients were classified into response group (a decrease in HBI≥3 or a decrease in SES-CD≥50%) and non-response group. TRAIL (rs1131568) gene polymorphism was analyzed by matrix-assisted laser desorption/ionization time of flight mass spectrometry technique. The plasma sTRAIL level was examined by enzyme-linked immunosorbent assay (ELISA). Based on the Montreal CD classification criteria, all CD patients were divided into different subgroups. Finally, a comprehensive analysis was performed to investigate the relationship between TRAIL (rs1131568) gene polymorphism, the plasma sTRAIL level and the risk of CD, the clinicopathological characteristics of CD patients, and the clinical response to IFX. Results: The recessive model analysis showed that the homozygous variant genotype (CC) was more prevalent in patients with moderately to severely active CD than in those with mildly active CD (45.34% vs 29.23%, P=0.005). Both variant allele (C) and homozygous variant genotype (CC) in patients with stricturing and penetrating CD were more frequent than those in patients with non-stricturing and non-penetrating CD (65.48% vs 57.53%, P=0.046; 49.21% vs 31.18%, P=0.001). The dominant model analysis showed that variant allele (C) and variant genotype (TC+CC) was higher in CD patients with perianal lesions than in those without perianal lesions (66.83% vs 58.17%, P=0.037; 92.31% vs 78.37%, P=0.002). The average plasma sTRAIL level was higher in CD patients than in healthy controls [(243.04±42.74) ng/L vs (194.16±31.14) ng/L, P<0.001]. Compared with the patients with mildly active CD, the plasma sTRAIL level was increased in those with moderately to severely active CD [263.47(242.09, 281.91) ng/L vs 231.13(211.11, 247.11) ng/L, P<0.001]. The same conclusion was also drawn for the patients with stricturing and penetrating CD in contrast to those with non-stricturing and non-penetrating CD [266.18 (246.68, 289.91) ng/L vs 227.19 (204.57, 249.59) ng/L, P<0.001]. The plasma sTRAIL level was also higher in patients with perianal disease than in those without perianal disease [(261.40±41.51) ng/L vs (233.86±40.41) ng/L, P<0.001]. Multiple linear regression analysis further showed that disease activity (β=22.640, P<0.001) and homozygous variant genotype (CC) (β=16.814, P<0.001) may be positively related to the plasma sTRAIL level in CD patients independently. At the 14th week of IFX treatment, the plasma sTRAIL level in the response group was lower than that in the non-response group [205.98(190.72, 214.56) ng/L vs (238.33±29.38) ng/L, P<0.001]. Compared with week 0, the plasma sTRAIL level was decreased in the response group in the 14th week [(205.98 (190.72, 214.56) ng/L vs (239.89±42.43) ng/L, P<0.001]. Non-conditional logistic regression analysis showed that variant allele (C) and variant genotype (TC+CC) were less frequent in the response group than in the non-response group (53.33% vs 70.83%, P=0.037; 70.00% vs 91.67%, P=0.036). Conclusions: The increased plasma sTRAIL level may be a risk factor for CD. TRAIL (rs1131568) gene variation and the increase of plasma sTRAIL level may be associated with the increased disease activity of CD and may be the risk factors for stenosis, penetration, and perianal lesions in CD patients. In addition, TRAIL (rs1131568) gene variation or the increase of plasma sTRAIL level may be related to no response to IFX treatment in CD patients.

Abstract
OBJECTIVE This paper aims to explore the diagnostic value of enhanced magnetic resonance imaging (MRI) combined with a carcinoembryonic antigen (CEA) and carbohydrate antigen in terms of the liver metastasis of colorectal cancer. METHODS A total of 167 colorectal cancer patients with liver metastasis and 167 colorectal cancer patients without liver metastasis were selected as the subjects. An automatic electrochemiluminescence analyser was then used to detect the tumour markers CEA, CA19-9, CA125 and CA72-4. The consistency between the MRI examination and clinical pathological examination was also analysed, and the sensitivity, specificity and positive and negative predictive values of various combined detection methods were compared. RESULTS The abnormal rates of CEA, CA19-9, CA125 and CA72-4 in the two groups were statistically significant (P < 0.05), while the results of the enhanced MRI and clinicopathological examination for liver metastasis in patients with colon cancer were largely consistent (Kappa coefficient = 0.788, P < 0.000). However, the two methods were inconsistent. The false positive rate of the enhanced MRI examination was 15.3%, while the false negative rate was 6.0%. The specificity (94.61%), positive predictive value (92.68%) and positive likelihood ratio (12.67%) were the highest for the MRI combined with serial CEA, while the sensitivity (98.80%) and negative predictive value (97.22%) were the highest with the MRI combined with parallel CEA, and this combination returned the lowest negative likelihood ratio (0.03). CONCLUSION The combination of MRI and CEA excludes non-metastatic patients and identifies colorectal liver metastasis cancer patients. Overall, it has a higher diagnostic value.

Abstract
Objective: A multicenter Chinese mainland survey was conducted to investigate the sensitization distribution characteristics of cat, dog and horse dander in patients with allergic diseases, so as to provide clinicians with epidemiological data of common animal allergens and useful information for the prevention and treatment of allergies in cats, dogs and horses. Methods: The epidemiological investigation and design was adopted. This study is based on the national epidemiological survey of allergic diseases led by the first affiliated Hospital of Guangzhou Medical University. From January to December in 2021, a total of 2 122 patients diagnosed with allergic diseases were included in the outpatient department of respiratory department/pediatrics/allergy department of 14 units such as the First Affiliated Hospital of Guangzhou Medical University, and 222 healthy subjects were included as controls from the physical examination center of the above units in the same period. All the subjects filled out the allergic disease questionnaire under the guidance of doctors, and the allergen-specific immunoglobulin E (sIgE) of cats, dogs and horses of all subjects were detected by magnetic particle chemiluminescence system. The epidemiological characteristics of three animal allergens in different diseases, ages and regions were analyzed. Chi square test was used to analyze the frequency difference between groups, t test or Mann Whitney U test was used to test the distribution difference between two groups, and one-way ANOVA or Kruskal Wallis H test was used to compare the distribution difference between multiple groups. Bar chart, Venn-plot and radar chart were drawn to show the sensitization distribution characteristics. A small number of missing values caused by subjects' omission have been excluded during the analysis. Results: The 2 122 patients with allergic diseases were 57.35% male (1 217/2 122) and 40.95% female (869/2 122), and 1.70% (36/2 122) patients had loss of gender information. The age of patients with allergic diseases was 9.0 (6.0, 28.0) years, while that of healthy controls was 29.0 (13.0, 39.0) years old, and there were 1.7% (36/2 122) and 0.9% (2/222) subjects with missing age information, respectively. The proportion of caesarean section in allergic patients was significantly higher than that in healthy controls (31.4% vs. 17.6%,χ2=16.582,P<0.001) [2.5% (54/2 122) of the patient group and 5.4% (12/222) of the control group had missing birth mode information], and the proportion of patients with allergic diseases who reported that both parents had allergic diseases was significantly higher than that of the control group (35.7% vs. 9.5%, χ2=65.171,P<0.001). Patients with allergic diseases are mainly school-age (6-12 years old) and adolescents (12-18 years old). 16.4% of patients with allergic diseases were sensitized to cat dander, 10% and 6% to dog and horse dander. The sensitization rate of cat dander in patients with rhinitis, asthma, conjunctivitis, food allergy and atopic dermatitis was the highest (16.4%-21.6%), followed by dog dander (10.2%-15.2%). The prevalence of allergic rhinitis was the highest among different animal sensitized populations. The proportion of cat, dog and horse allergens sensitized at the same time is between 10%-15%, and the proportion of any two or more animal dander sensitized at the same time is about 45%. Animal allergens are associated with respiratory allergic diseases, especially allergic rhinitis with allergic conjunctivitis. There were significant differences in the distribution of positive rates of three animal allergens in different regions, and the highest positive rate of cat dander was found in all provinces of the country. Conclusion: The sensitization rate of animal dander allergens increased significantly, and the highest was in children and adolescents. Cat dander is the most common animal allergen, followed by dog. Different animals show obvious cross or common sensitization due to their high homology.

Abstract
Objective: To analyze the influence of vitamin D3 supplementation on the clinical efficacy of mesalazine in patients with ulcerative colitis (UC). Methods: From January 2015 to December 2020, patients with mild-to-moderate active UC were retrospectively and continuously enrolled, who accepted mesalazine treatment for at least 12 months at the Second Affiliated Hospital of Wenzhou Medical University. According to simultaneous supplement of vitamin D3 (125 IU/d), the patients were divided into study group and control group. Demographic and disease characteristics, serum 25-hydroxyvitamin D[25(OH)D] levels and other information were collected through retrieving hospital database. Student's t-test, Mann-Whitney U test and Chi-square test were applied for comparison of disease characteristics. The changes of modified Mayo scores[ΔMayo] and 25(OH)D[Δ25(OH)D] were compared before and after treatment by paired t-test, Wilcoxon signed rank test and Chi-square test. Multiple linear regression model was used to analyze the independent factors affecting ΔMayo and Δ25(OH)D, and variables with P-values less than 0.20 in the univariate analysis were allowed for further multivariate analysis. Results: A total of 74 UC patients (44 males, 30 females), with median age (range) 39.5 (20-76) years old, were analyzed and respectively assigned into study group (n=36) and control group (n=38). In study group, the average level of serum 25(OH)D was significantly increased at month 12 compared with that at baseline [(22.87±7.30) μg/L vs. (18.15±7.48) μg/L,P<0.001]. However, no significant elevation of serum 25(OH)D was found in control group [(19.17±8.49) μg/L vs. (19.82±9.47) μg/L,P=0.466]. Furthermore, there was a significant decrease of modified Mayo score [-3(-4.75, -1.25) vs.-2(-3.25, 0), P=0.034] and a higher clinical remission rate (55.6% vs. 28.9%, P=0.020) at month 12 in study group than those in control group. In addition, according to the baseline level of serum 25(OH)D before mesalazine treatment, 74 UC patients were divided into vitamin D deficiency group (n=38, serum 25(OH)D<20 μg/L) and non-deficiency group (n=36, serum 25(OH)D≥20 μg/L). At month 12 in vitamin D deficiency group, patients with vitamin D3 supplementation had a greater decline in modified Mayo score [-4(-5.75, -2) vs.-2(-4, 0), P=0.048] and a higher clinical remission rate (60.0% vs. 22.2%, P=0.019) compared with those without. Conclusions: In patients with mild-to-moderate active UC receiving mesalazine treatment, vitamin D3 supplementation may improve the clinical efficacy, especially in patients with vitamin D deficiency.

Abstract
Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

Abstract
OBJECTIVE To evaluate the impact of the flood disaster on schistosomiasis transmission along the Yangtze River basin in 2020, so as to provide insights into schistosomiasis prevention and control in flood-affected areas. METHODS The data pertaining to the endemic situation of schistosomiasis were collected from 5 provinces of Hunan, Hubei, Jiangxi, Anhui and Jiangsu from 2013 to 2019, including Schistosoma japonicum infections in humans and livestock and snail distribution, and the warning water levels and actual water status were collected in water regions locating in these 5 provinces. The cumulative numbers of S. japonicum egg-positive individuals and bovines during the period from 2013 to 2019, the area of snail habitats in 2019 and the water level on July 12, 2020 were estimated at a county level and employed as parameters for classification of schistosomiasis transmission risk. Then, the cumulative value of each risk index was calculated to assess the risk of schistosomiasis transmission risk. RESULTS After the flood disaster along the Yangtze River basin in 2020, there were 10, 5 and 9 counties (districts) at high risk of schistosomiasis transmission in 5 provinces of Hunan, Hubei, Jiangxi, Anhui and Jiangsu based on number of egg-positive individuals, number of egg-positive bovines and snail distribution, respectively. Based on comprehensive risk indices, there were 10 (8 in Dongting Lake regions of Hunan Province and 2 in Poyang Lake regions of Jiangxi Province) and 15 counties (districts) (4 in Hubei Province, 7 in Hunan Province and 4 in Jiangxi Province) identified at grades 5 and 4 risk of schistosomiasis transmission. CONCLUSIONS Dongting Lake regions and Poyang Lake regions are the most severely flood-affected schistosomiasis-endemic foci of China in 2020, and the flood disaster may facilitate the transmission of schistosomiasis in affected areas. Therefore, schistosomiasis control requires to be intensified after the flood disaster to prevent the rebound of the disease.

Abstract
OBJECTIVE To assess whether the same biological conclusion, diagnostic or curative effects regarding microbial composition of irritable bowel syndrome (IBS) patients could be reached through different bioinformatics pipelines, we used two common bioinformatics pipelines (Uparse V2.0 and Mothur V1.39.5)to analyze the same fecal microbial 16S rRNA high-throughput sequencing data. METHODS The two pipelines were used to analyze the diversity and richness of fecal microbial 16S rRNA high-throughput sequencing data of 27 samples, including 9 healthy controls (HC group), 9 diarrhea IBS patients before (IBS group) and after Rifaximin treatment (IBS-treatment, IBSt group). Analyses such as microbial diversity, principal co-ordinates analysis (PCoA), nonmetric multidimensional scaling (NMDS) and linear discriminant analysis effect size (LEfSe) were used to find out the microbial differences among HC group vs. IBS group and IBS group vs. IBSt group. RESULTS (1) Microbial composition comparison of the 27 samples in the two pipelines showed significant variations at both family and genera levels while no significant variations at phylum level; (2) There was no significant difference in the comparison of HC vs. IBS or IBS vs. IBSt (Uparse: HC vs. IBS, F=0.98, P=0.445; IBS vs. IBSt, F=0.47,P=0.926; Mothur: HC vs.IBS, F=0.82, P=0.646; IBS vs. IBSt, F=0.37, P=0.961). The Shannon index was significantly decreased in IBSt; (3) Both workshops distinguished the significantly enriched genera between HC and IBS groups. For example, Nitrosomonas and Paraprevotella increased while Pseudoalteromonadaceae and Anaerotruncus decreased in HC group through Uparse pipeline, nevertheless Roseburia 62 increased while Butyricicoccus and Moraxellaceae decreased in HC group through Mothur pipeline.Only Uparse pipeline could pick out significant genera between IBS and IBSt, such as Pseudobutyricibrio, Clostridiaceae 1 and Clostridiumsensustricto 1. CONCLUSION There were taxonomic and phylogenetic diversity differences between the two pipelines, Mothur can get more taxonomic details because the count number of each taxonomic level is higher. Both pipelines could distinguish the significantly enriched genera between HC and IBS groups, but Uparse was more capable to identity the difference between IBS and IBSt groups. To increase the reproducibility and reliability and to retain the consistency among similar studies, it is very important to consider the impact on different pipelines.

Abstract
Recent studies have shown that radiofrequency (RF) ablation therapy is a safe, feasible, and effective procedure for hepatic hemangiomas, even huge hepatic hemangiomas. RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.

Abstract
Objective: To explore the status of glucocorticoid application in patients with systemic lupus erythematosus (SLE) in China. Methods: Epidemiological survey was used. The SLE patients who met the 1997 classification criteria of American College of Rheumatology were enrolled. The usage of glucocorticoid and related adverse reactions were recorded and analyzed. Results: A total of 400 SLE patients were enrolled, including 35 men and 365 women. The average age was (37.4±14.0) years old, and the average duration of disease was (6.7±5.8) years. There were 310 patients using glucocorticoid as maintenance. Sixty-one percent (n=244) patients started using medium dose (prednisone 30-<60 mg/d) as the initial treatment of glucocorticoid, which lasted for(37±11)days.The time of drug duration in patients with low dose prednisone (7.5-<30 mg/d)and high dose (60-100 mg/d) was(92±20)and(17±3)days respectively (P<0.05 between 3 groups). However, patients receiving different initial dosage were of no discrepancy in the maintenance therapy. During maintenance, even though 51.0% (n=158) patients were on prednisone 2.5-5 mg/d, the duration of drug use in >5-10 mg/d groupwas longer[(29.9±3.3) months]. Patients with involvement of internal organs had a higher tendency to use 60-100 mg/d prednisone or pulse-dose therapy in the initial treatment, nevertheless these two groups had no difference of maintenance dosage. Among all 400 patients, 62 patients withdrew glucocorticoid, including 17 patients with disease remission (4.3%), 44 by self-withdrawal and one with adverse reaction. Conclusion: In China, the medium dosage of glucocorticoid is the most common initial treatment in patients with SLE.Prednisone 2.5-5 mg/d was the most common choicefor maintenance therapy. Currently, the proportion of glucocorticoid withdrawal remains low in SLE patients achieving remission.

Abstract
Objective: To investigate the influence of depression levels on regulatory T cells (Tregs) in patients with non-M3 acute myeloid leukemia (AML). Methods: A total of 63 patients with primarily diagnostic non-M3 AML and 25 healthy controls were enrolled, and the levels of depression by using HADM score and the percentages of Tregs by flow cytometry were evaluated in pre-treatment and post-treatment, respectively. Results: After every course of chemotherapy, the percentages of Tregs of PBMNC in AML showed the higher level of (6.48±1.81)% than those of (4.99±1.29)% in control (P= 0.001). There was no difference among different levels of depression groups after the first cycle. However, the percentages of Tregs increased with the worse of depression after the second and third cycles. Partial correlation analysis after adjusting age indicated that the percentages of Tregs showed no correlation with the levels of depression after the first cycle (correlation coefficient, 0.120, P=0.345), and showed the positive correlation with depression levels after the second and third cycles (correlation coefficient, 0.619 and 0.614, all P values <0.05). Conclusion: The depression levels showed an association with the percentages of Tregs in patients with non-M3 AML, which could be observed only after the second cycles of chemotherapy.

Abstract
Metformin, an oral biguanide drug used to treat type 2 diabetes, has displayed anticancer activities in several types of cancer cells. The combination of gemcitabine and cisplatin is the standard chemotherapy regimen for cholangiocarcinoma, but its benefit is limited. The present study aimed to investigate whether metformin could enhance the activities of gemcitabine and cisplatin against cholangiocarcinoma, and the underlying mechanisms. Metformin inhibited the proliferation of human cholangiocarcinoma RBE and HCCC-9810 cells and induced cell cycle arrest at the G0/G1 phase by increasing the activation of AMP-activated protein kinase (AMPK) pathways. Metformin upregulated the expression of p21Waf1 and p27kip1, and downregulated the expression of cyclin D1, a key protein required for cell cycle progression. The combination of gemcitabine and cisplatin inhibited the proliferation and induced the apoptosis of human cholangiocarcinoma cells by inducing the phosphorylation of AMPK, downregulating cyclin D1, and activating caspase-3. Administration of metformin enhanced the efficacy of gemcitabine and cisplatin to suppress the growth of cholangiocarcinoma tumors established in experimental models by inhibiting cell proliferation and inducing cell apoptosis through their effects on AMPK, cyclin D1 and caspase-3. Given that metformin has been used to treat type 2 diabetes patients for over half a century due to its superior safety profile, the results presented here indicate that metformin may be a potent agent for enhancing the efficacy of gemcitabine and cisplatin in the treatment of cholangiocarcinoma.

Abstract
The complementary DNA (cDNA) of the giant panda (Ailuropoda melanoleuca) ferritin light polypeptide (FTL) gene was successfully cloned using reverse transcription-polymerase chain reaction technology. We constructed a recombinant expression vector containing FTL cDNA and overexpressed it in Escherichia coli using pET28a plasmids. The expressed protein was then purified by nickel chelate affinity chromatography. The cloned cDNA fragment was 580 bp long and contained an open reading frame of 525 bp. The deduced protein sequence was composed of 175 amino acids and had an estimated molecular weight of 19.90 kDa, with an isoelectric point of 5.53. Topology prediction revealed one N-glycosylation site, two casein kinase II phosphorylation sites, one N-myristoylation site, two protein kinase C phosphorylation sites, and one cell attachment sequence. Alignment indicated that the nucleotide and deduced amino acid sequences are highly conserved across several mammals, including Homo sapiens, Cavia porcellus, Equus caballus, and Felis catus, among others. The FTL gene was readily expressed in E. coli, which gave rise to the accumulation of a polypeptide of the expected size (25.50 kDa, including an N-terminal polyhistidine tag).

Abstract
MicroRNAs (miRNAs) are short, non-coding RNAs with post-transcriptional regulatory function, playing crucial roles in cancer development and progression of hepatocellular carcinoma (HCC). Previous studies have indicated that miR-1180 was implicated in diverse biological processes. However, the underlying mechanism of miR-1180 in HCC has not been intensively investigated. In this study, we aimed to investigate the role of miR-1180 and its target genes in HCC. We found that miR-1180 expression was significantly increased in HCC cells and clinical tissues compared with their corresponding controls. Overexpression of miR-1180 promoted cell proliferation in HCC cell line HepG2. TNFAIP3 interacting protein 2 (TNIP2), a potential target gene of miR-1180, and were validated by a luciferase assay. Further studies revealed that miR-1180 regulated cell proliferation of HCC by directly suppressing TNIP2 expression and the knockdown of TNIP2 expression reversed the effect of miR-1180-in on HCC cell proliferation. In summary, our data indicated that miR-1180 might act as a tumor promoter by targeting TNIP2 during development of HCC.

Abstract
ADPN I148M polymorphism has been consistently reported to play a role in liver-associated diseases, such as alcoholic liver disease, chronic hepatitis C, and liver fat and fibrosis in nonalcoholic fatty liver disease. This significant association was also indicated in a series of hepatocellular carcinoma (HCC) studies, where the significance may be affected due to the small sample sizes. The aim of this study was to reexamine the ADPN-HCC association by use of meta-analysis. Biweekly computer-based literature searches plus manual screening were undertaken in an effort to identify all studies that met the predefined inclusion criteria. The Mantel-Haenszel method was selected to estimate risk effects (odds ratio [OR] and 95% confidence interval [CI]). To examine reliability of the pooled risk effects, we additionally performed sensitivity analysis and publication bias tests. Ten studies (1335 HCC patients and 2927 HCC-free controls) were identified for the meta-analysis. We found significantly increased risk of HCC attributable to presence of ADPN I148M polymorphism, with the highest risk associated with the M/M genotype under the recessive model of inheritance (OR = 2.23, 95% CI = 1.87-2.67, between-study heterogeneity: P = 0.468). The significant increase persisted in Caucasian and African when data were stratified by ethnicity. Subgroup analysis according to source of controls revealed similar risk effects. Our meta-analysis indicates that I148M polymorphism in the ADPN gene may independently contribute to the progression of HCC irrespective of the etiologies.

Abstract
OBJECTIVE To find out if there are any relationship between three single nucleotide polymorphisms (SNPs) of phosphatase and tensin homolog (PTEN) gene (rs1234213, rs1234220, and rs2299939) and the susceptibility of liver cancer. METHODS Genotypes of the three SNPs in the PTEN gene were achieved utilizing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Comparison of genotypes and alleles distribution differences between the case and the control subjects was accomplished with χ(2) test. The analysis of linkage disequilibrium (LD) and haplotypes of the three SNPs was performed using SHEsis software. We adopted odds ratios (ORs) with 95% confidence intervals (95% CIs) to show the relative risk of liver cancer. RESULTS TC genotype and C allele of rs1234220 polymorphism showed much more frequently in cases than in controls, reflecting that the TC genotype and the C allele may be linked to the increased risk of liver cancer (OR=2.225, 95% CI=1.178-4.204; OR=1.941, 95% CI=1.124-3.351). Rs2299939 polymorphism showed an opposite result that the GT genotype probably reduce the risk of liver cancer (OR=0.483, 95% CI=0.259-0.900). Statistical significance was not found in the distribution differences of the genotypes of rs1234213 between two groups. LD and haplotype analysis results of the three SNPs showed that the T-C-G haplotype frequency was much higher in cases than in healthy objects, which proved that the T-C-G haplotype might be a susceptibility haplotype for liver cancer (OR=3.750, 95% CI=1.396-10.077). CONCLUSIONS PTEN gene polymorphisms might relate to liver cancer risk.

Abstract
PURPOSE Our study was carried out to explore the relationship of PIK3CA rs17849071 and rs17849079 polymorphisms with the susceptibility to hepatocellular carcinoma (HCC) in Chinese Han population. METHODS 150 HCC patients and 152 healthy individuals were recruited in the case and control groups respectively. The genotypes of PIK3CA rs17849071 and rs17849079 polymorphisms were detected with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The linkage disequilibrium and haplotypes were analyzed with Haploview software. Differences in frequencies of genotypes, alleles, and haplotypes between the case and control groups were checked with χ(2) test. The controls were matched with the cases in age and gender. The relative risk of HCC was represented by odds ratio (OR) and 95% confidence interval (95% CI). RESULTS Significant difference in frequencies of GG genotype and G allele in PIK3CA rs17849071 polymorphism existed between the two groups (P=0.040; P=0.028), indicating that rs17849071 was closely related to the increased risk of HCC (OR=2.919, 95% CI=1.007-8.460; OR=1.642, 95% CI=1.051-2.564). Furthermore, TT genotype also significantly increased the susceptibility to HCC (OR=3.438, 95% CI=1.050-11.250) and so was T allele (OR=1.521, 95% CI=1.052-2.199). The haplotype analysisshowed that G-T haplotypes were higher in cases than that of controls (P=0.030), which suggested that G-T might be a susceptible haplotype to HCC. CONCLUSIONS The PIK3CA rs17849071 and rs17849079 polymorphisms may increase the risk of HCC either independently or synergistically.

Abstract
Hepatocellular carcinoma (HCC) is a heterogeneous disease with substantial genetic constitution. Previous work has evaluated the effect of prostaglandin-endoperoxide synthase 2 (PTGS2) variants (-765G/C, -1195A/G, and +8473T/C) on the development of HCC, but the conclusions are inconsistent. We conducted a meta-analysis in this work. Data from 7 case-control studies were combined to assess the association between PTGS2 variants and HCC. The risk of HCC (OR and 95% CI) was estimated using either the fixed- or the random-effects model according to the Q test. No significant association was identified for -765G/C and +8473T/C. However, we identified a significantly decreased risk in relation to the GG genotype of -1195A/G (OR = 0.70, 95% CI = 0.50-0.98 for GG versus AA). We also observed a similar decrease (OR = 0.47, 95% CI = 0.23-0.95 for GG versus AA) in Caucasian samples. Variant -1195A/G in the promoter PTGS2 may protect against the malignant progression of HCC. This significant association suggests that -1195A/G could be used as a biomarker of HCC.

Abstract
OBJECTIVES To explore the molecular mechanism of hepatitis B virus-related and hepatitis C virus-related hepatocellular carcinoma, samples from hepatitis B virus and hepatitis C virus infected patients and the normal were compared, respectively. METHODS In both experiments, genes with high value were selected based on a genome-wide relative significance and genome-wide global significance model. Co-expression network of the selected genes was constructed, and transcription factors in the network were identified. Molecular complex detection algorithm was used to obtain sub-networks. RESULTS Based on the new model, the top 300 genes were selected. Co-expression network was constructed and transcription factors were identified. We obtained two common genes FCN2 and CXCL14, and two common transcription factors RFX5 and EZH2. In hepatitis B virus experiment, cluster 1 and 3 had the higher value. In cluster 1, ten of the 17 genes and one transcription factor were all reported associated with hepatocellular carcinoma. In cluster 3, transcription factor ESR1 was reported related with hepatocellular carcinoma. In hepatitis C virus experiment, the value of cluster 3 and 4 was higher. In cluster 3, nine genes were reported to play a key role in hepatocellular carcinoma. In cluster 4, there were 5 genes in the 34 genes. To compare the relevance of a node in holding together communicating nodes, centralities based analysis was performed and we obtained some genes with high stress value. CONCLUSION The analysis above helped us to understand the pathogenesis of hepatitis B virus and hepatitis C virus associated hepatocellular carcinoma.

Abstract
Chinese redbud (Cercis chinensis Bunge), a member of the Fabaceae, is an important ornamental plant native to China with reported desirable medicinal effects, including stimulating blood circulation, detumescence, and detoxification (1). In October 2011, wilt symptoms of gradual leaf yellowing, wilting, scorching (marginal browning), and twig dieback were observed on plants in Yangling, Shaanxi, China. The incidence of diseased plants was about 20% in two main areas (about 20 ha in Zijingshan Park in Zhengzhou, Henan Province; and about 3,000 ha in Taiping National Forest Park in Xi'an, Shaanxi Province). Wilted leaves of diseased plant senesced and died, but defoliation was not observed. Brown discoloration was observed in vascular tissues of petioles, twigs, and stems of diseased plants, sometimes in a ring pattern. The symptoms were often restricted to the lower part of the tree or a few branches. To identify the causal agent, six twigs (each approximately 50 mm in diameter and 10 cm long) sampled from an infected tree in Yangling were rinsed in running water, surface-sterilized with 75% ethanol for 2 min, rinsed in sterilized water three times, dried, cut into 1 cm long segments, and the segments put onto potato dextrose agar (PDA) medium. A fungal isolate was recovered from diseased vascular tissues of each sample when cultured on PDA in the dark at 25°C. After 5 days, colonies changed from white to black as a result of production of microsclerotia. Microscopic observation revealed that conidiophores were hyaline and verticillate, with three to four phialides at each node. Conidia were ellipsoidal, hyaline, single-celled, and 2.5 to 7.5 × 1.25 to 4.5 μm. On the basis of these morphological characteristics, the fungus was identified as Verticillium dahliae (3). To prove Koch's postulates, the roots of 10 healthy, 1-year-old C. chinensis plants were each irrigated in a greenhouse with 50 ml of a conidial suspension (1.0 × 107 spores/ml) of an isolate recovered from an infected plant (2); five control plants were inoculated similarly with sterilized water. Fifteen days after inoculation, the same wilt symptoms observed on the original plants had developed on 9 of the 10 inoculated plants, whereas the control plants remained healthy. The pathogen was recovered 15 days after inoculation by isolating from petiole and stem tissues of symptomatic plants, but was not isolated from the control plants. The internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2) of the nuclear ribosomal DNA was PCR-amplified with primers ITS1 and ITS4 (4), and sequenced. BLAST analysis of the ITS sequence (GenBank Accession No. AB735536) showed 100% homology with that of an isolate of V. dahliae (FJ572050). To our knowledge, this is the first report of Verticillium wilt on C. chinensis in China. References: (1) Y. Li et al. J. Integr. Plant Biol. 47:1021, 2005. (2) H. A. Melouk and C. E. Horner.

Abstract
The ribosomal protein L24 (RPL24) belongs to the L24E family of ribosomal proteins and is located in the cytoplasm. The purpose of this study was to investigate the structure and anti-cancer function of RPL24 of the giant panda (Ailuropoda melanoleuca). The complementary DNA of RPL24 was cloned successfully using reverse transcription-polymerase chain reaction technology. We constructed a recombinant expression vector containing RPL24 complementary DNA and overexpressed it in Escherichia coli using pET28a plasmids. The expression product obtained was purified using Ni-chelating affinity chromatography. The results indicated that the length of the fragment cloned is 509 bp, and it contains an open-reading frame of 474 bp encoding 157 amino acids. Primary structure analysis revealed that the molecular weight of the putative RPL24 protein is 17.78 kDa with a theoretical isoelectric point of 11.86. The RPL24 gene is readily expressed in E. coli, and the RPL24 fused with the N-terminal histidine-tagged protein to give rise to the accumulation of an expected 23.51-kDa polypeptide. The inhibitory rate in mice treated with 0.1 mg/mL RPL24, the highest of 3 doses administered, can reach 67.662%, which may be comparable to the response to mannatide. The histology of organs with tumors showed that the tissues in the RPL24 group displayed a looser arrangement compared with that in the control group. Furthermore, no obvious damage was apparent in other organs, such as heart, lung, and kidney. The data showed that the recombinant RPL24 had time and dose dependency on the cell growth inhibition rate. Human laryngeal carcinoma Hep-2 cells treated with 0.3125-10 µg/mL RPL24 for 24 h displayed significant cell growth inhibition (P < 0.05; N = 6) in assays using 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide compared with that in control (untreated) cells. By contrast, human hepatoma Hep G-2 cells displayed no significant change (P > 0.05; N = 6) from control (untreated) cells. RPL24 has time and dose dependency on Hep-2 cell growth inhibition. The data indicate that the effect at low concentrations is better than that at high concentrations, and the concentration of 0.625 µg/mL provides the best rate of growth inhibition. Further research is ongoing to determine the bioactive principles of recombinant RPL24 protein that are responsible for its anticancer activity.

Abstract
OBJECTIVE To investigate the effect of M(5) muscarinic receptor subtype on the locomotor sensitization induced by heroin priming, and it's effect on the FosB expression in the nucleus accumbens (NAc) and the hippocampus in the heroin sensitized rats. METHODS Locomotor activity was measured every 10 min for 1 h after subcutaneous injection of heroin. FosB expression was assayed by immunohistochemistry, and the antisense oligonucleotides (AS-ONs) targeting M(5) muscarinic receptor was transferred with the lipofectin. RESULTS Microinjection of AS-ONs targeting M(5) muscarinic receptor in the ventral tegmental area (VTA) blocked the expression of behavioral sensitization induced by heroin priming in rats. Meanwhile, the expression of FosB-positive neurons in either the NAc or the dentate gyrus (DG) of the hippocampus increased in heroin-induced locomotor sensitized rats. The enhancement of FosB-positive neurons in the NAc or DG could be inhibited by microinjection of M(5) muscarinic receptor AS-ONs into the VTA before the heroin-induced locomotor sensitization was performed. In contrast, microinjection of M(5) muscarinic receptor sense oligonucleotide (S-ONs) into the VTA did not block the expression of behavioral sensitization or the expression of FosB in the NAc or DG in the heroin sensitized rats. CONCLUSION Blocking M(5) muscarinic receptor in the VTA inhibits the expression of heroin-induced locomotor sensitization, which is associated with the regulation of FosB expression in the NAc and hippocampus neurons. M(5) muscarinic receptor may be a useful pharmacological target for the treatment of heroin addiction.

Abstract
Iterative reconstruction methods such as the expectation maximization maximum likelihood (EMML) method can be accelerated by using a rescaled block-iterative (RBI) algorithm. It was demonstrated that the space-alternating generalized expectation-maximization (SAGE) algorithm is superior to the EMML due to the following facts: (1) The hidden data spaces can be appropriately chosen and then be used in SAGE algorithm to speed up the convergence rate. (2) SAGE algorithm updates the parameters sequentially which makes its M-step to be treated more easily. In this paper, we present a novel algorithm that combines the RBI algorithm with SAGE algorithm. The convergence property of RBI-SAGE is discussed, and the image quality is assessed with mean absolute error and chi-square error. The experimental results show that the proposed method is more effective than the SAGE algorithm even if the projection data includes statistic noise.

Abstract
This work presents a new iterative method for reconstructing positron emission tomography (PET) images. Unlike conventional maximum likelihood-expectation maximization (MLEM), this method intends to introduce the fuzzy set principle to MLEM algorithm. In this work, the noncognitive uncertainty of the observed projection data are described by their probability density function; whereas the cognitive uncertainty of a random variable can be described by the membership function for its fuzziness. The mean of the observed projection data are regard as fuzzy random variables because of the complexity of system. The fuzzy random variable can be represented by a triangular membership function. We establish a joint probability density function that includes the effects of both fuzziness and randomness. The maximum likelihood approach is used to estimate the image vector. The order subset (OS), rescaled block-iterative (RBI), and row-action (RA) techniques are applied to our PET reconstructed method to speed up the convergence rate and to decrease the iteration numbers.

Abstract
Infectious cDNA clones of the Shanghai isolate of Ribgrass mosaic virus (RMV) were produced by joining four overlapping cDNA fragments and also in a single step by long template PCR. After inoculation of Nicotiana glutinosa with either RNA transcripts or the cDNA under the control of the CaMV 35S promoter, plants developed typical symptoms, and viral coat protein could be detected in them by Western blot analysis. However, compared to plants inoculated with purified viral RNA, lesions were fewer and appeared more slowly. An epitope of the Mycobacterium tuberculosis 31-kDa protein was inserted at the C-terminus of the viral coat protein by PCR using two overlapping fragments. The modified clone was also infectious and the foreign epitope could be detected serologically in the electron microscope and by Western blot analysis. The results demonstrate the potential of RMV as a viral gene vector.

Abstract
OBJECTIVE To study the relationship between the livestock trade and schistosomiasis transmission and to provide an evidence for making a strategy of schistosomiasis control in mountainous areas. METHODS A retrospective survey and analysis was conducted to investigate the prevalence of schistosomiasis in both humans and livestock (cattle, horses, mules, donkeys and pigs), and the number and migration of livestock in Weishan County, Yunnan Province in 1980-1991. RESULTS A positive correlation was found between the infection rate of residents and the numbers of livestock migration (R = 0.9151, P < 0.01). During 1980 to 1991 the infection rate was increased gradually along with the development of livestock husbandry, especially, from the economic reforms since 1984. In 1984 there was positive correlation in the infection rate both human and livestock (R = 0.8458, P < 0.05). The results show that the infection rates of livestock on sale including cattle, horses, mules, donkeys and pigs are 9.54%, 29.39%, 16.38%, 14.47%, 25.73% and 11.11%, respectively. CONCLUSION The infection rate of human and livestock arises by parallel. The high frequency of livestock trade resulted in serious spreading of the infection source of schistosomiasis. The migration of the infected livestock might be an important factor in transmitting schistosomiasis.

Abstract
The morphology of t-PA mutant engineered cell line FSGGI48 is similar to that of CHO-dhfr- cell in polygon. When aminopterin (MTX) concentration is 5 x 10(-6) mol/L, a part of cells become slim, but they are still in polygon. Therefore, the morphology of FSGGI48 cell line is normal. The expression level is 4000 IU/10(6) cells/24 h in serum-free medium. The cell line is bequeathed for three months in vitro and revived after freezing three months, the greater part of cells are stable. The expression level is 3000-4000 IU/10(6) cells/24 h. The assay of tumorigenesis shows that the cells, cellular DNA and purified products don't form tumors in nude mice. The cell line hasn't been contaminated by mycoplasma. The results of chromosomal analysis show that the chromosomal number of CHO-dhfr- cell is 20 and the abnormal rate is 6%. FSGGI48 cell line is same as CHO-dhfr- cell in chromosomal number and the abnormal rate is 15%-18%, it is normal in scope. Therefore, the engineered cell line FSGGI48 is excellent.

Abstract
Bevantolol (Bev, 5, 10 mg.kg-1) was injected i.v. to rabbits. A measure the lag time of heart rate (HR) response behind the changes in plasma Bev concentration (K(eo)), and the sensitivity of the site of action of Bev (EC50) were determined. The K(eo) were 0.03 +/- 0.02 and 0.029 +/- 0.009 min-1 and the EC50 were 0.2 +/- 0.1 and 0.27 +/- 0.14 microgram.ml-1 respectively for the 2 dosages. The peak changes in HR lagged behind the changes in plasma Bev concentration. There were no significant changes in both pharmacokinetic and pharmacodynamic parameters between the dosages.
