Objectives To assess the clinical value of ultrasonography (US) and bioelectrical impedance analysis (BIA) in analyzing abdominal fat contents of obese children and adolescents through comparison with MRI. A correlation with other obese related metabolic parameters was conducted. Methods Ninety 7-17-y-old obese children and adolescents (60 boys and 30 girls with mean age of 9.6 ± 2.9 y and mean BMI of 24.5 ± 4.5 kg/m2) were recruited. Metabolic parameters were measured, and insulin resistance was estimated according to homeostasis model assess-ment (HOMA-IR). On the same day abdomen subcutaneous fat thickness (SFTUS) was measured by US. Body fat mass (FMBIA) and abdominal visceral fat area (VFABIA) were analyzed by bioelectrical impedance analysis (BIA). After obtaining informed consent, abdominal MRI was performed in 20 subjects. Each section of umbilicus level was analyzed by image threshold value segmentation using SigmaScan Pro 5 and abdominal subcutaneous fat area (SFAMRI) and visceral fat area (VFAMRI) were calculated. Results (1) A strong positive association was found between SFTUS and SFAMRI (P< 0.05), VFABIA and VFAMRI (P < 0.01) respectively. (2) FMBIA and SFAMRI, VFAMRI, SFTUS also showed significant correlations (P < 0.05). (3) VFAMRI showed extremely significant positive correlations with TG, Insulin,C-peptide and HOMA-IR (P < 0.01 ) ; SFAMRI was also correlated positively with them (P < 0.05). (4) SFTUS was correlated positively with UA (uric acid), Insulin, 2HIns (insulin measured at 2 hours after meal), C-peptide,2HC-peptide (C-peptide measured at 2 hours after meal) and HOMA-IR (P < 0.01). (5) VFABIA was correlated significant positively with UA, insulin, TG, 2HIns and HOMA-IR. FMBIA showed positive correlation with UA, Insulin,2HIns, C-peptide, 2HC-peptide and HOMA-IR. Conclusions abdominal subcutaneous and visceral fat of obese children and adolescents evaluated by US and BIA are correlated well with those assessed by MRI, and also correlated well with TG, insulin, C-peptide and other metabolic biochemical parameters. Our data support the value of using cost effective, simple and convenient methods such as BIA and US to evaluate the obese and related metabolic risk of children and adolescents in clinical practice.

BACKGROUND:To construct tissue engineering cartilage would open up a novel way for the repair of cartilage damage in avoidance of the disadvantages of traditional therapeutic method.OBJECTIVE: To probe the techniques for the isolation of mesenchymal stem cells (MSCs) from bone marrow, as well as the in vitro differentiation into chondrocytic phenotype in a specific culture fluid.DESIGN:A complete randomized experimentSETTING:The Department of Traumatic Orthopedics and Hand Surgery of the First Affiliated Hospital of Guangxi Medical University, and Teaching and Research Faculty of Histology and Embryology of Guangxi Medical University.METHODS: The experiment was carried out at Guangxi Medical University between August 2002 and April 2003. Twenty SD neonatal weaning rats were selected. Bone marrow was aspirated from the bones of rat limbs and was isolated by gradient centrifugation in Percoll, and MSCs could be obtained in combination with adherent screening method, which were then cultured in DMEM-LG with 15% fatal bovine serum (FBS) in the incubator of 37℃ with 5% CO2 for 10-14 days. The passage cells were induced in DMEM-HG with 15% FBS (containing TGF-β1 10 μg/L, 10-7 mol/L dexamethasone, 50 mg/L VitC).MAIN OUTCOME MEASURES :The morphology, growth, as well as proliferation and specific expression of chondrogenic matrix of in vitro cultured MSCs due to specific induction.RESULTS: Totally 20 SD rats were observed and analyzed with no loss SCs grew in visible symmetric colonies, displaying a long-spindle shape,and the morphological characteristics of marrow-derived MSCs had no obvious changes during passage-culture, but its proliferation time was found from a shuttle fibroblastic appearance to polygonal shape, displaying posiHC staining of type Ⅱ collagen of cartilage specific matrix.bronectin adherent screening technique is a convenient, effective and practical method to separate and collect MSCs from rat bone marrows in chondrogenic phenotype when induced by a specific medium and can secrete cartilage specific matrix, and they can be the optimal seed cells for cartilage tissue engineering.

Objective To investigate the mycobactericidal efficacy of linezolid on multidrugresistant tuberculosis (MDR-TB) and nontuberculous mycobacteria (NTM) in vitro.Methods Seven hundred and sixty-two Mycobacterium tuberculosis and 20 NTM isolates from Hangzhou were identified by using hsp65 gene sequencing from March to June,2013.Seventy MDR-TB isolates,which were screened by using proportion method,and twenty NTM isolates were tested the MIC to linezolid,and the differences of MICs to linezolid between MDR-TB and NTM werw analyzed in vitro.Results All 70 MDR-TB isolates were inhibited at concentrations of ≤ 1 mg/L by linezolid,MIC50 was 0.5 mg/L and MIC90 1 mg/L.Of all 8 isolates inhibited at concentration of 1 mg/L,there were 6 isolates resistant to isoniazid,rifampin,streptomycin and ethambutol,suggesting this resistance pattern may reduce sensitivity to linezolid.Among the NTM isolates,18 Mycobacterium intracellulare isolates,whose MICs to linezolid at 8-16 mg/L,were non-resistant isolates,while 2 Mycobacterium abscessus isolates displaying MICs ＞ 32 mg/L,were resistant to linezolid.Conclusions Linezolid showed great activity to MDR-TB and there were no linezolid-resistant MDR-TB isolates identified in this study.However,MICs of MDR-TB against linezolid increased with their resistant numbers to first-line agents.This study also showed that different NTM species have varied sensitivity to linezolid.

Objective To establish a system for detecting integration frequency of antibiotic resist-ante integron.Methods We cloned integron and aadA2 gene cassette into different sites of plasmid pACYC 184,and the plasmid was transformed into E.coli BL21(DE3)containing plasmid overexpressing integrase.The positive clone was cultured overnight and then was spread on LB agar plate with or without streptomycin respectively,and with appropriate amount of bacteria.Clones after cultured overnight were counted to detect the integration frequency.Meanwhile we used positive clones in LB agar plate containing streptomycin as templates to carry out PCR.The purified PCR products were sequenced to identify the integration sites.Re-suits The integration frequency of integron capturing aadA2 gene cassette in BL21(DE3) host was 1.1 x 10-3 mainly at attI site.Conclusion This system can be used to detect integration frequency.

Carthamus tinctorius L. is a traditional Chinese medicine with the effect of promoting blood circulation and removing blood stasis. HSYA (hydroxysafflor yellow A) is the main effective component of Carthamus tinctorius L. In order to study the inhibitory effects of HSYA against PMN (polymorphonuclear) activation induced by LPS (lipopolysaccharide), rabbit PMN adhesion potency which was activated by LPS through colorimetry method was observed. Cellular free calcium concentration was determined by fluorescence spectrophotometry. RT-PCR was applied to study the effect of HSYA on PMN TNF-alpha and IL-6 mRNA expression; The inhibition of HSYA on NF-kappaB activation was monitored with immunofluorescence. The results showed that after treated with HSYA, the increase of adhesion potency (HSYA dose 1.01 x 10(-4) mol x L(-1)), free calcium concentration (HSYA dose 3.1 x 10(-5) mol x L(-1)), TNF-alpha and IL-6 mRNA expression elevation (HSYA dose 5.2 x 10(-1) mol x L(-1)) induced by LPS were inhibited. HSYA can inhibit NF-kappaB p65 subgroup nuclear translocation (HSYA dose 5.2 x 10(-5) mol x L(-1)). It is suggested that HSYA is effective in PMN activation induced by LPS.

BACKGROUND:Transplantation of mesenchymal stem cells (MSCs) to multiple sclerosis (MS) is a new developed treatment to be given more and more attention.However,whether the MSCs function by cell replacement after going cross the blood-brain barricr or immune suppression needs further confirmation.OBJECTIVE:To establish a steady and effective method of Y chromosome in situ hybridization (ISH) and to detect the distribution of MSCs in a mouse model with MS.DESIGN,TIME AND SETTING:The observational study was performed at the Laboratory of Molecular Immunology,Institute of Healthy Science from September 2007 to February 2009.MATERIALS:A total of 30 C57BL/6 mice,aged 6-8 weeks and weighing 15-20 g,were selected.Female mice were used to establish experimental autoimmune encephalomyelitis (EAE).METHODS:Y chromosme specific DNA probe labled with digoxine (DIG) was designed and ISH was performed to confirm that the designed probe was Y chromosome specific and biologically sensitive.We transplanted the MSCs from male mice into the female EAE mice,and tracked the MSCs by Y chromosome ISH.MAIN OUTCOME MEASRUES:Distribution of MSCs in mice with EAE was observed under the optical and fluorescence microscope.RESULTS:The probe was confirmed to be Y chromosome specific and biologically sensitive.What's more,a steady and effective method of ISH was established.Some MSCs were detected in the periphery organs-spleen and lymph node of mice with EAE;seldom in spinal cord which indicated that MSCs might play its roles by immune suppression.CONCLUSION:Some MSCs were detected in the periphery organs-spleen and lymph node of mice with EAE,but seldom in spinal cord in the central nervous system.
