Objective To study renal involvement in hepatic glycogen storage disease(GSD) in childhood. Methods One hundred and eight patients aged less than 21 years old with type Ⅰa GSD (54 cases), type Ⅲ (29 cases) and uncertain type hepatic GSD (25 cases). Urine analysis, urine albumin, urine protein of 24 h, urine ?_2-MG, BUN, creatinine, Ccr were evaluated. Results Of 108 patients with hepatic GSD, 16 patients (20.8%) had proteinuria proven by urine albumin or urine protein of 24 h, their ages first found proteinuria were 8～15 years. Two 15-year-old patients had proteinuria over 1.0g/24h. Among 72 patients, urine ?_2-MG of 51 cases (70.8%) increased (175～10 623mg/L), and the mean urine ?_2-MG of type Ⅰ a GSD was much higher than that of type Ⅲ GSD, 4138.2 and 1790.1mg/L respectively. Of 91 patients, 10 had renal insufficiency, 1/10 (15-year-old girl) had heavy proteinuria (3.5g/24h), elevated BUN (9.3mmol/L) and Scr(1061 ?mol/L). Five elder patients (11～21 years old) had hematuria with renal colic caused by renal calculus. Conclusions Persistent protenuria, increased urine ?_2-MG, decreased Ccr, and renal stones are common complications of hepatic GSD in childhood. Renal function should be thoroughly evaluated during follow-up.

Objective To establish antigen capture ELISA methed to detect Kaposi's sarcoma-as-sociated herpesvirus(KSHV)antigen,and to evaluate its feasibility for clinical application.Methods The BALB/c mice and New Zealand white rabbits were injected with purified recombinant KSHV gpK8.1 proteins to prepare the monoclonal antibody(McAb)and polyclonal antibody(PcAb)anti-gpK8.1,respectively.A new antigen capture ELISA method was established for KSHV antigen detection.The detection reproducibili-ty as well as the sensitivity and specificity of this new assay were determined by the optimization test,which antibody pairs were analyzed to choose the best coating antibody and detecting antibody.The 3 KSHV posi-tive patients sera and 257 patients sera from sexually transmitted disease,cancers or gynecological diseases were detected with this assay to evaluate its value for clinical application.Results When the McAb as coat-ing antibody at concentration of 5 μg/ml and PcAb as detecting antibody at concentration of 1.6μg/ml were selected,the highest P/N value could be obtained.The sensitive analysis of this test could detect recombi-nant KSHV gpK8.1 antigen of 31.28 ng/ml.Meanwhile,it is highly specific to detect KSHV antigen with-out cross reaction to Epstein-Barr vims(EBV),herpes simplex virus(HSV)-1 or HSV-2.All of three KSHV-positive sera and 4 sera from 257 clinical samples were positive with this new assay.which indicated that it could be used for capturing KSHV antigen.Conclusion A sensitive and specific McAb-based anti-gen capture ELISA method to detect KSHV antigen were established successfully.It is of great potential val-ue to develop reagent for KSHV clinical serologic dingnosis.

Objective To explore the role of glycogen synthase kinase (GSK)-3β/β-catenin signaling pathway on human immunodeficiency virus 1 (HIV-1) negative factor (Nef) protein promoting of human herpesvirus-8 (HHV-8) viral interleukin-6 (vIL-6)-induced angiogenesis.Methods GSK-3β mutant plasmid GSK-3β-S9A,dominant negative (DN) form GSK-3β-DN and the control vector pcDNA3.1+ were transfected into endothelial cells which stably expressed HHV-8 vIL-6 or HIV-1 Nef,or co-expressed vIL-6 and Nef protein.Microtubule formation assay was performed to explore microtubule formation ability.A chick embryo chorioallantoic membrane (CAM) model was used to detect angiogenesis.The expression of GSK-3β/β-catenin signaling pathway-related kinases in transfected cells and CAM tissue were further detected by Western blot.The measurement data were compared by t test.Results The activity of GSK-3β was decreased and the ability of HIV-1 Nef protein was enhanced by transfection with GSK-3β-DN in promoting vIL-6 induced microtubule formation (3.42 vs 2.51,t =3.67,P＜0.01) and angiogenesis (6.25 vs 3.97,t=4.06,P＜0.01).In contrast,the activity of GSK-3β was significantly increased and these functions of HIV-1 Nef protein mentioned above were inhibited by transfection with GSK-3β-S9A (0.62 vs2.51,t=8.48,P＜0.01; 0.39 vs 3.97,t=8.59,P＜0.01).The results of Western blot showed that with the elevated level of,β-catenin (in cells:3.53 vs 2.07,t=6.60,P＜0.05; in tissues:2.76 vs 1.74,t=17.40,P＜0.01) and vascular endothelial growth factor (VEGF,in cells:2.68 vs 1.87,t=4.28,P＜0.01; in tissues:2.20 vs 1.39,t=7.08,P＜0.01) were increased in the GSK-3β-DN transfected cells or tissues,while the opposite results were achieved in the GSK-3β-S9A-transfected cells (GSK-3β phosphorylation:0.50 vs 1.47,t=7.33,P＜0.01; β-catenin:1.05 vs 2.62,t=29.50,P＜0.01; VEGF:0.74 vs 2.16,t=20.95,P＜0.01) or tissues (GSK-3β phosphorylation:0.35 vs 1.97,t=10.72,P＜0.01; β-catenin:0.79 vs 1.77,t=5.72,P＜0.01; VEGF:0.43 vs 1.65,t=11.89,P＜ 0.01).Conclusion GSK-3β/β-catenin signaling pathway is involved in vIL-6-induced angiogenesis promoted by HIV-1 Nef protein,which would be valuable for the therapy of Kaposi's sarcoma,an acquired immunodeficiency syndrome,as a potential molecular target.

Objective:To investigate the changes in gut microbiota diversity with age in elderly people using high-throughput sequencing.Methods:Ninety healthy volunteers were recruited. People who were <60 years old (middle-aged group) were set up as a baseline control group (Age A group), while those aged ≥60 years old were further divided into four groups (60-<70: Age B group, 70-<80: Age C group, 80-<90: Age D group, ≥90: Age E group). Fecal samples were collected to extract DNA. The second-generation sequencing technology was used to amplify and sequence the V3-V4 hypervariable region of 16S rDNA. Bioinformatics analysis was performed to compare the differences in gut microbiota and functional genes among groups.Results:At the phylum level, gut microbiota were composed mainly of Firmicute, Bacteroidetes, Proteobacteria and Actinobacteria in different groups. The proportion of Firmicute was the highest, accounting for over 60%, followed by that of Bacteroidetes. At the genus level, the abundance of Faecalibacterium genus decreased with age. The α diversity analysis showed that the gut microbiota in the elderly of different ages had higher abundance and uniformity, and there was no significant difference among groups. However, the β diversity analysis showed that in community structure there was difference between Age A and Age B groups, and similarity between Age B and Age C groups. Conclusions:The community structure of gut microbiota changed significantly between young and middle-aged people and the elderly over 60 years old. It tended to be relatively stable in people of 60-80 years old, but changed again when they were over 80 years old. Chronic inflammatory diseases, metabolic diseases and tumors in the elderly might be associated with the decrease in Faecalibacterium.

Aromatic compounds are a class of organic compounds with benzene ring(s). Aromatic compounds are hardly decomposed due to its stable structure and can be accumulated in the food cycle, posing a great threat to the ecological environment and human health. Bacteria have a strong catabolic ability to degrade various refractory organic contaminants (e.g., polycyclic aromatic hydrocarbons, PAHs). The adsorption and transportation are prerequisites for the catabolism of aromatic compounds by bacteria. While remarkable progress has been made in understanding the metabolism of aromatic compounds in bacterial degraders, the systems responsible for the uptake and transport of aromatic compounds are poorly understood. Here we summarize the effect of cell-surface hydrophobicity, biofilm formation, and bacterial chemotaxis on the bacterial adsorption of aromatic compounds. Besides, the effects of outer membrane transport systems (such as FadL family, TonB-dependent receptors, and OmpW family), and inner membrane transport systems (such as major facilitator superfamily (MFS) transporter and ATP-binding cassette (ABC) transporter) involved in the membrane transport of these compounds are summarized. Moreover, the mechanism of transmembrane transport is also discussed. This review may serve as a reference for the prevention and remediation of aromatic pollutants.
