The incidence of aduIt obesity,diabetes,hyperIipidemia and hypertention has been rising dramaticaIIy in recent years. Obesity and overweight have become a significant pubIic heaIth probIem worIdwide. Though obesity is caused by compIex interactions between genetic,behavioraI,and environ-mentaI factors,its etioIogy is stiII uncIear. There is growing evidence that exposure to bisphenoI A(BPA) during prenataI and neonataI or adoIescence periods Ieads to much body mass gain. In addition,in epi-demioIogicaI studies,the association between BPA exposure and obesity and type 2 diabetes has been found. The potentiaI mechanism may be attributed to promoted differentiation and function in adipocytes via aIteration of a number of genes. BPA may act aIso through other mechanisms. It can directIy bind to nucIear receptors acting as agonists or antagonists and indirectIy disrupt hormone IeveIs by inhibiting enzymatic activity or by activating expression of the P450 enzymes. This review is focused on the effects of estrogenic endocrine disrupting chemicaIs such as BPA on the deveIopment of obesity.

Objective To investigate the influence of hedysaryum polysaccharide (HPS)in the kidney function and expressions of Glut-1 mRNA and protein in kidney tissue of db/db mice with diabetic nephropathy (DN)and to elucidate its possible action mechanism.Methods 10 db/m mice were taken as normal control group(n=10);50 fueling animal model db/db mice with DN were randomly divided into model group,enalapril group and the low, middle and high doses of HPS groups(n=10).The mice in noral control group and model group were given physioloical saline by gavege;and the mice in the other groups were respectively given 10 mg·kg-1 ·d-1 enalapril, 100,200 and 400 mg·kg-1 ·d-1 HPS by gavage;lasted 8 weeks.Picric acid method was used to determine the serum creatinine(SCr)level of the mice,enzyme coupling rate method was used to determine the blood urea nitrogen (BUN)level,ELISA method was used to determine the urinary microalbumin(UMALB)level,RT-PCR method was performed to detect the expression of Glut-1 mRNA, and Western blotting and immunohistochemical methods were used to detect the expression of Glut-1 protein.Results Compared with model group,the levels of SCr, BUN, UMALB, the mRNA and protein of Glut-1 expressions were decreased, especially in 400 mg·kg-1 ·d-1 HPS and enalapril groups(P<0.01).The HE and Masson staining results showed that less inflammatory cells infiltration in glomerular of the mice were found, capillary lumens were unobstructed, and the collagen deposition was not obvious in 400 mg·kg-1 ·d-1 group.Conclusion HPS could improve the kidney function of the db/db mice and inhibit the Glut-1 mRNA and protein expressions obviously, which indicates that HPS could delay the development of DN by inhibiting the Glut-1 expression in the glomerular mesangial cell membrane.

OBJECTIVETo screen DENV-2 binding proteins from Aedes albopictus and Culex. quinquefasciatus.

METHODSThe total proteins of Aedes albopictus and Culex. quinquefasciatus in different developmental stages were prepared and analyzed with SDS-12% polyacrylamide gel. After electrophoresis the proteins were transferred using Mini Trans-Blot Electrophoretic Transfer Cell (Bio-Rad ) to a nitrocellulose membrane. Virus overlay protein-binding assay (VOPBA) was carried out using anti-dengue virus 1-4 monoclonal antibody.

RESULTSIn Aedes albopictus, VOPBA detected DEN-2 binding molecules of 25 000, 35 000, and 50 000 in larvae samples, molecules of 35 000 and 50 000 in pupae samples, a 50 000 molecule in male mosquito samples, and molecules of 35 000 and 50 000 in female mosquito samples. DENV-2 binding protein of 35 000 was found in the larvae, pupae, and female mosquitoes, but not in male mosquitoes. In Culex. Quinquefasciatus, VOPBA detected a molecule of 100 000 in larvae samples, molecules of 40 000, 100 000, and around 50 000 (48 000 and 60 000) in pupae samples, and molecules of 40 000 and 100 000 in male mosquitoes and female mosquito samples.

CONCLUSIONSeveral proteins capable of binding DENV are found in Aedes albopictus and Culex. quinquefasciatus in different development stages. The 35 000 molecule expressed in Aedes albopictus as a putative receptor protein may be related to virus tropism in mosquito tissues.

Objective To report 9 HIV-negative patients with talaromycosis marueffei (TSM)complicated by Sweet syndrome,and to analyze the relationship of the anti-interferon-γ (anti-IFN-γ)autoantibody with TSM complicated by Sweet syndrome.Methods HIV-negative patients with TSM complicated by Sweet syndrome were collected from the First Affiliated Hospital of Guangxi Medical University between 2013 and 2018.Their clinical and laboratory data were analyzed retrospectively.Meanwhile,19 HIV-positive patients with TSM and 107 health checkup examinees served as controls.Anti-IFN-γ autoantibody was detected in peripheral blood samples of the patients and controls.Results A total of 9 HIV-negative patients with TSM (5 males and 4 females) were included in this study,and the age of onset ranged from 38 to 60 years.The 9 patients all presented with disseminated infections,manifesting as long-term irregular fever,multiple lymph node enlargement,cough,emaciation and anemia.All of the 9 patients met the diagnostic criteria for classical Sweet syndrome,and microbiological examination of Sweet syndrome lesions was negative.Besides Talaromyces marneffei,6 patients also were infected with nontuberculous mycobacteria,4 with varicella-zoster virus,and 2 with Salmonella.All the 9 HIV-negative patients with TSM were positive for anti-IFN-γ autoantibody,while the 107 healthy controls and 19 HIV-positive patients with TSM were negative for anti-IFN-γ autoantibody.Conclusion Anti-IFN-γ autoantibody may be associated with HIV-negative TSM complicated by Sweet syndrome.

Objective: To investigate the feasibility of multiplex real-time RT-PCR with fluorescent probes in early screening of Ph-like acute lymphoblastic leukemia (ALL) and analyze the clinical feature and prognos. Method: A total of 118 adult B-ALL patients diagnosed between October 2010 and March 2016 were enrolled in this study. Multiplex RT-PCR was used to detect the Ph-like ALL related fusion gene and CRLF2 expression in 58 BCR-ABL and MLL rearrangement negative patients. The clinical features, treatment response and prognosis were analyzed in Ph-like fusion gene positive and/or CRLF2 over-expression patients. Result: Among 58 patients, 9 patients (9/58, 15.5%) showed Ph-like ALL related fusion genes positive and 10 patients (10/58, 17.2%) showed CRLF2 over-expression. There were statistical differences in age, WBC count, immunophenotypes, cytogenetics and risk stratification among Ph-like fusion gene positive or CRLF2 over-expression patients, Ph⁺ patients, MLL⁺ patients and B-other patients. The 2-year overall survival rates were 65%, 47%, 64% and 74% respectively among these four groups (P=0.043) . The 2-year relapse free survival rates were 51%, 39%, 62% and 70% respectively among these four groups (P=0.010) . Conclusion Routine screening of Ph-like ALL by multiplex RTPCR is feasible.

Objective: To investigate the spectrum of gene mutations in adult patients with B-acute lymphoblastic leukemia (B-ALL), and to analyze the influences of different gene mutations on prognosis. Methods: DNA samples from 113 adult B-ALL patients who administered from June 2009 to September 2015 were collected. Target-specific next generation sequencing (NGS) approach was used to analyze the mutations of 112 genes (focused on the specific mutational hotspots) and all putative mutations were compared against multiple databases to calculate the frequency spectrum. The impact of gene mutation on the patients’ overall survival (OS) and recurrence free survival (RFS) was analyzed by the putative mutations through Kaplan-Meier, and Cox regression methods. Results: Of the 113 patients, 103 (92.0%) harbored at least one mutation and 29 (25.6%) harbored more than 3 genes mutation. The five most frequently mutated genes in B-ALL are SF1, FAT1, MPL, PTPN11 and NRAS. Gene mutations are different between Ph⁺ B-ALL and Ph^- B-ALL patients. Ph^- B-ALL patients with JAK-STAT signal pathway related gene mutation, such as JAK1/JAK2 mutation showed a poor prognosis compared to the patients without mutation (OS: P=0.011, 0.001; RFS: P=0.014,<0.001). Patients with PTPN11 mutation showed better survival than those without mutation, but the difference was not statistically significant (P value > 0.05). Besides, in Ph⁺ B-ALL patients whose epigenetic modifications related signaling pathway genes were affected, they had a worse prognosis (OS: P=0.038; RFS: P=0.047). Conclusion Gene mutations are common in adult ALL patients, a variety of signaling pathways are involved. The frequency and spectrum are varied in different types of B-ALL. JAK family gene mutation usually indicates poor prognosis. The co-occurrence of somatic mutations in adult B-ALL patients indicate the genetic complex and instability of adult B-ALL patients.
