Effects of squalene, algae (Enteromorpha prolifera), laver (Prophyra hai-tanensis) and cauliflower on serum total cholesterol (T-C), high density li-poprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) were separatly observed in Wistar male albino rats fed on a diet containing 0.5% cholesterol,5% lard and 0.5% bile salt. Squalene was supplemented at 5% of the diet, and algae, laver, cauliflower at 10% of the diet.After the rats had been fed on the diet described above for 30 days, serum T-C, HDL-C, LDL-C and VLDL-C levels were determined. The results showed that the rats fed on a diet containing 5% squalene or 10% algae were significantly lower in serum T-C, HDL-C and VLDL-C but higher in serum HDL-C than those of the controls, and the rats fed on a diet containing 10% laver or 10% cauliflower were significantly lower in serum T-C than that of the controls.

Objective To study the rule of lower-cervical lymphatic metastasis in thoracic esophageal carcinoma,and make evaluation about the reasonable extent of lymphadenectomy. Methods One hundred and eight cases of thoracic esophageal carcinoma through chromatic ultrasound and CT before operation were divided into different groups selectively,while three fields lymphadenectomy (3-FL) was adopted in 31 cases,and two fields lymphadenctomy (2-FL) was adopted in 77 cases. Results The rate of lower-cervical lymphatic metastasis was 87.1%(27/31) through chromatic ultrasound and CT,and that was 25.0%(27/108) before the two up-mentioned examinations (P<0.05). In all cases, the rate of lower-cervical lymphatic metastasis in the upper pectoral esophageal carcinoma was 47.6% (10/21),that in the middle pectoral esophageal carcinoma was 21.3%(13161),and that in the middle and lower pectoral esophageal carcinoma was 19.5%(17187) ,P<0.05. Through 3-FL, the rate of lower--cervical lymphatic metastasis in the upper pectoral esophageal eareinoma was 57.1%(12/21), that in the middle pectoral esophageal carcinoma was 23.0%(14/61), and that in the middle and lower pectoral esophageal carcinoma was 21.8%(19/87), P<0.05. Conclusions The regionality metastasis is the main fashion in thoracic esophageal carcinoma with lower-cervical lymphatic metastasis. It is feasible to judge lower-cervical lymphatic metastasis through chromatic ultrasound and CT before operation.The 3-FL of the upper pectoral esophageal carcinoma is recommended. The 3-FL is selectable in the middle and lower pectoral esophageal carcinoma according to the result of chromatic ultrasound and CT.

Objective To investigate the point prevalence rate of social anxiety disorder (SAD) in Chengdu primary school, and analyze the influencing factors. Methods Data came from a large representative sample of Chengdu 1441 primary school students, who were selected by stratified cluster sampling methods. They then finished self-compiled questionnaire, strengths and difficulties questionnaire, Eysenck Personality Inventory (EPI) (age 7 ～ 15 ), Egma Minnen ay Bardndosnauppforstran (EMBU) respectively. And then they had the face to face interviews with the trained psychiatrists, according to development and well - being assessment ( DAWBA,Chinese Version). Results Among 1441 Chengdu primary students, 37 of them were diagnosed SAD,with a point prevalence of 2.6% totally. The point prevalence was different in each grades, for 2.7% in grade 3,4. 1% in grade 4,4.1% in grade 5,3.5% in grade 6( z= -2.3, P=0. 023 ). Compared with the normal counterparts ,the SAD students had statistically significance different in pro-socialization ( z = -2. 1, P = 0.035 ), affection(z=- 5.2, P = 0. 001 ) , moral conduct ( z = - 2.8, P = 0. 004 ), peer( z = - 3.1, P = 0.002 ), excessive interference of maternal education ( z = - 3.1, P = 0.002 ), introversion-extroversion ( z = - 2. 0, P = 0. 046 ), neuroticism ( z =- 3.5, P= 0. 000), concealing tendency ( z= - 2.3, P= 0.018 ). Logistic regression analysis showed that: grade,family location, habitual lifestyle over the past years more emotional problem and excessive interference of maternal education were related with SAD occurrence. Conclusion The point prevalence rate of social anxiety disorder among Chengdu primary students is 2.6% ,and it was influenced by a number of factors .

Objective To investigate the efficacy and white matter integrity of low frequency repetitive transcranial magnetic stimulation (rTMS) and the modified electroconvulsive therapy (MECT) in patients with schizophrenia. Methods From May 2015 to October 2016,120 cases with schizophrenia were randomly enrolled into the MECT group and of the rTMS group. Patients in the MECT group were treated with the modified electric convulsive therapy for 8 times ,while patients in the rTMS group were treated with the repetitive transcranial magnetic stimulation for 12 times. PANSS were used to evalue the clinical effects. Repeatable battery for the assess-ment of neuropsychological status was used to assess the cognitive function. Treatment emergent side-effect scale was used to assess the adverse effects. Brain fractional anisotropy was used to assess white matter integrity. Results After treatment,the PANSS scores were significantly lowered,however,the RBANS scores were signifi-cantly higher in the MECT group and rTMS group than those before treatment ,with significant differences (P <0.05). No significant differences for the PANSS scores and the RBANS scores were observed between the two groups before and after treatment. There was no significant difference for the TESS scores between the two groups before treatment(P > 0.05). After treatment,the TESS scores in the MECT group were significantly higher than those in the rTMS group(P < 0.05). After treatment,the FA values of left anterior cingulate gyrus,left posterior cingulate gyrus ,left prefrontal cortex and genu of corpus callosum for both MECT group and rTMS group were significantly increased (P < 0.05 ,respectively). Compared with the MECT group ,the FA value significantly increased in the rTMS group after treatment (P < 0.05). Conclusions Both MECT and rTMS have significant clinical efficacies and can improve the cognitive function of schizophrenics. rTMS is more safe than MECT ,with a stronger effect on preventing the integrity of white matter than MECT.

Objective The aim of this study was to screen and verify the proteins interacting with Vimentin,investigate the regulatory relationship between FABP5 and candidate proteins,and further explore the mechanism of FABP5 in hepatocellular carcinoma.Methods Immunoprecipitation combined with tandem mass spectrometry(IP-MS)was used to screen the proteins that bind to FABP5.The binding relationship between FABP5 and candi-date interacting proteins was verified from the exogenous and endogenous levels by Co-immune precipitation assay(Co-IP).RT-qPCR,Western blot and immunofluorescence were used to observe the effect of knockdown FABP5 on the transcription and translation of Vimentin in HCC cells.The effect of overexpressing FABP5 on the cytoskeleton of HCC cell was observed by phalloidin staining.Results 336 potential target proteins that bind to FABP5 were identi-fied through IP-MS.Based on literature,five candidate proteins related to tumors were selected,namely PRDX1,PRSS3,PKM,HSP90AA1,and Vimentin.The binding relationship between FABP5 and Vimentin protein was con-firmed through both exogenous and endogenous Co-IP.Knockdown FABP5 has no significant effect on the expression of Vimentin mRNA,but it can inhibit the expression of Vimentin protein,and overexpression of FABP5 can affect the cytoskeleton of HCC cell.Conclusions FABP5 promotes the migration and invasion of HCC cells by the regula-tion of Vimentin and the influence of cytoskeletal remodeling,and thus it is expected to be a potential target for anti-HCC and provide new ideas for the treatment of HCC.

BACKGROUNDFUS2 gene locating at 3p21.3 is considered a promising candidate tumor suppressor gene. The aim of this study is to examine the difference in FUS2-767A/T polymorphism site between lung cancer patients and normal controls in Chinese population.

METHODSThe genotype FUS2-767A/T was detected in 146 lung cancer patients and 113 normal controls by PCR-SSCP method. The relationship between lung cancer risk and difference in genotypes of FUS2 gene was analysed.

RESULTSFUS2-767A/T was significantly related to histological type (P=0.044), age of the patients with lung cancer (P=0.011) and vessel cancer embolus (P=0.031) in lung cancer group. There was no significant difference in distribution of FUS2 genotypes between lung cancer patients and normal controls (P=0.945).

CONCLUSIONSThe results suggest that the FUS2-767A/T polymorphism may be a susceptibility factor for lung cancer among Chinese population.

Objective To evaluate the feasibility of secondary transplantation for patients with acute leukemia after failure of the first haploidentical hematopoietic stem cell transplantation. Methods Two acute leukemia patients underwent the first haploidentical hematopoietic stem cell transplantation from two donors with thalassemia, and the number of collected CD34⁺ cells was 2.57×10⁶/kg and 1.99×10⁶/kg per donor, respectively. The first haploidentical hematopoietic stem cell transplantation failed. Secondary transplantation was performed from two non-thalassemia donors, and the number of collected CD34⁺ cells was 4.28×10⁶/kg and 5.75×10⁶/kg per donor, respectively. A reduced-intensity conditioning regimen consisting of fludarabine (Flu), busulfan (Bu) and antithymocyte globulin (ATG) was adopted for the secondary transplantation. Results For two recipients, the time of secondary transplantation of neutrophil and platelet was +12 d and +10 d, +10 d and +10 d, respectively. Up to the final follow-up (+1 062 d and +265 d after secondary transplantation), the primary diseases of both two recipients have been completely relieved without evident post-transplantation complications. Conclusions Secondary transplantation with reduced-intensity conditioning regimen may successfully treat acute leukemia after failure of the first haploidentical hematopoietic stem cell transplantation.

OBJECTIVETo explore common biological pathways for attention deficit hyperactivity disorder (ADHD) and low birth weight (LBW).

METHODSThei-Gsea4GwasV2 software was used to analyze the result of genome-wide association analysis (GWAS) for LBW (pathways were derived from Reactome), and nominally significant (P< 0.05, FDR< 0.25) pathways were tested for replication in ADHD.Significant pathways were analyzed with DAPPLE and Reatome FI software to identify genes involved in such pathways, with each cluster enriched with the gene ontology (GO). The Centiscape2.0 software was used to calculate the degree of genetic networks and the betweenness value to explore the core node (gene). Weighed gene co-expression network analysis (WGCNA) was then used to explore the co-expression of genes in these pathways.With gene expression data derived from BrainSpan, GO enrichment was carried out for each gene module.

RESULTSEleven significant biological pathways was identified in association with LBW, among which two (Selenoamino acid metabolism and Diseases associated with glycosaminoglycan metabolism) were replicated during subsequent ADHD analysis. Network analysis of 130 genes in these pathways revealed that some of the sub-networksare related with morphology of cerebellum, development of hippocampus, and plasticity of synaptic structure. Upon co-expression network analysis, 120 genes passed the quality control and were found to express in 3 gene modules. These modules are mainly related to the regulation of synaptic structure and activity regulation.

CONCLUSIONADHD and LBW share some biological regulation processes. Anomalies of such proces sesmay predispose to ADHD.
