[Summary] The genomic DNA was extracted from peripheral blood leukocyte of the patient with thyroid hormone resistance syndrome and 14 members of his family.The exons 1-10 of thyroid hormone receptor β (TRβ) gene were amplified by PCR.The products of PCR were sequenced directly to detect the gene mutation.The results showed that 3 members of this family were confirmed to have the C→T transition mutation at nucleotide 1 303 site within exon 10 of TRβ gene,and the missense mutation results in the substitution of histidine to tyrosine (H435Y).The heterozygous mutation may lead to the occurrence of thyroid hormone resistance syndrome.

Objective To investigate the expression and the effects of X-chromosome linked inhibi- tor of apoptosis (XIAP) associated factor 1 (XAF1) on apoptosis and cell proliferation in SMMC7721 hepatocellur carcinoma (HCC) cell line.Methods The expression of XAF1 mRNA and protein in hu- man SMMC7721 cell line were detected by semi-quantitative,RT-PCR and Western blot.Plasmid con- structs expressing sense and antisense XAF1 were generated and transfected into SMMC7721 cell line to establish stable transfectants.Cell proliferation and apoptosis were detected by MTT,flow cytometry and TUNEL.Results XAF1 mRNA and protein were detectable in SMMC7721 cell line but lower than that in normal liver cell.Stable expression of XAF1 significantly inhibited cell proliferation and increased spontaneous apoptosis in SMMC7721 cell (P＜0.05).Over-expression of XAF1 in stable transfactants increased the sensitivity of SMMC7721 cell to chemotherapeutic drugs such as 5-fluorouracial and hydroxycamptothecin.Conclusions Over-expression of XAF1 induces apoptosis and inhibits SMMC7721 cell growth.XAF1 may be a promising candidate for HCC gene therapy.

To establish single- and double-transfected transgenic cells stably expressing hMATE1, hMATE1 cDNA was cloned by RT-PCR from human cryopreserved kidney tissue, and subcloned into pcDNA3.1(+) plasmid by virtue of both HindIII and Kpn I restriction enzyme sites. Subsequently, the recombined pcDNA3.1(+)- hMATE1 plasmid was transfected into MDCK, MDCK-hOCT1 or MDCK-hOCT2 cells using Lipofectamine 2000 Reagent. After a 14-day-cultivation with hygromycin B at the concentration of 400 µg · mL(-1), all clones were screened with DAPI and MPP+ as substrates to identify the best candidate. The mRNA content of hMATE1, the cellular accumulation of metformin with or without cimetidine as inhibitor, or transportation of cimetidine was further valuated. The results showed that all of the three cell models over expressed hMATE1 mRNA. The cellular accumulation of metformin in MDCK-hMATE1 was 17.6 folds of the control cell, which was significantly inhibited by 100 µmol · L(-1) cimetidine. The transcellular transport parameter net efflux ratios of cimetidine across MDCK-hOCT1/hMATE1 and MDCK-hOCT2/hMATE1 monolayer were 17.5 and 3.65, respectively. In conclusion, cell models with good hMATE1 function have been established successfully, which can be applied to study the drug transport or drug-drug interaction involving hMATE1 alone or together with hOCT1/2 in vitro.

OBJECTIVETo explore the ultrastructural changes of hepatocyte fibrogenesis in cholelithiasis in biliary tract.

METHODSl0 liver biopsies were taken from the patients suffered from gallstone and choledocholithiasis during surgical treatment and the ultrastructural changes were observed under electromicroscope.

RESULTSThere were plentiful collagenous microfibrils (CMFs) grown within some hepatocytes. These CMFs distributed locally or diffusely in cytoplasm even extended into nucleus. In 7 cases numerous megamitochondrias appeared in several hepatocytes, the inclusions mimicking fibrils could be frequently seen and grew beyond the envelope. Furthermore, typical CMFs could be seen in the large microbodies, and several vesicular or cystic structures similar as fibroblast were presented in marginal areas of the hepatocytes.

CONCLUSIONSWe deduce that the fibrosed hepatocytes may be remained and take part in the hyperplasia of hepatic fibrous tissue.

The aim of this study is to improve liposome encapsulation efficiency of water soluble drug ATP-2Na with hydrophobic ion pairing method, and evaluate its effect on tissues energy state in myocardial ischemia mice. Ion pair complex of ATP-2Na with HTAB was prepared first; then the liposomes were prepared by ethanol injection method. The size and zeta potential of ATP-2Na liposome were investigated. Its effect on tissues energy state in myocardium ischemia mice was evaluated by detecting ATP-2Na concentration in tissues and blood after injection in comparison to ATP-2Na solution. The diameters and zeta potential of ATP-2Na liposomes were (144.0 +/- 2.7) nm and (+16.2 +/- 1.6) mV, respectively. The encapsulation efficiency was (85.02 +/- 2.31) %. The in vitro drug release pattern from liposomes matches with Weibull equation. Compared with ATP-2Na solution, ATP-2Na liposome increased the ATP concentration of blood in myocardial ischemic mice very significantly; compared with blank, ATP-2Na liposome increased ATP content of myocardium and liver in myocaridal ischemic mice significantly, but ATP-2Na solution didn't show this effect. ATP-2Na liposome might have an advantage in improving tissue energy state on myocaridal ischemic animals.

BACKGROUND:There is a great difference of grade size of macrobead in various joint diseases; therefore, it can be used to determine state of joint diseases initially.OBJECTTVE : To explore the physical properties of synovial fluid nano-particles and their correlations with the occurrence of knee osteoarthritis (KOA).DESIGN: Controlled experimental study based on synovial fluid samples.PARTICIPANTS: A total of 99 synovial fluid samples were collected from normal subjects and KOA patients with various KOA severities. Among them, 41 were normal synovial fluids, 58 were KOA.METHODS: Synovial fluid samples from individuals with and without KOA were obtained. Using the technology of quasi-elastic laser scattering, nano-particle size and its distribution were estimated, and the dynamic/static light scattering spectrometric analyzer allowed the measurement of particles Zeta potentials. A correlation analysis between the particle size, Zeta potentials and the onset of KOA was attempted.MAIN OUTCOME MEASURES:① Grade size and distribution of microsome in synovial fluid;② Zeta potentials and distribution of microsome in synovial fluid; ③ grade size and clinical correlation of microsome in synovial fluid.RESULTS: ① The mean nano-particle diameter in the synovial fluid of KOA patients were significantly greater than those of normal joints [(297±84), (63±23) nm, P ＜ 0.001]. The distribution curve of KOA synovial fluid nano-particle size was normal knee and (-15.84 ±3.34) mV of KOA patients, and there was a significant difference (P ＜ 0.001). This suggestedthat the Zeta potentials in the synovial fluid of KOA patients were significantly greater than those of normal joints. ③ The average particle size and Zeta potential of synovial fluid strongly correlated with the integrity of the joint of KOA (rp =0.797 2,0.631 9, P＜ 0.01).CONCLUSION: The nano-particle size and Zeta potential of synovial fluid are significantly correlated with the development of KOA, and this can reflect the severity of KOA.

Objective To apply color Doppler flow imaging (CDFI) and transcranial Doppler (TCD) to the follow-up observation of the changes of cervical vessel,intracranial hemodynamics and cerebrovascular reserve capacity (CVR) of the patients after carotid artery stent implantation.Methods Totally 96 patients with carotid artery stent implantation underwent CDFI and TCD examinations,and the changes of hemodynamics were compared before and 1 month,6 months,1 a and 2 a after implantation.Results The values of peak systolic velocity (PSV) and resistance index (RI) at the areas of carotid stenosis were lower significantly than those before implantation,while the values of PSV,pulsatility index (PI) and CVR of the middle cerebral artery were obviously higher than those before implantation (P＜0.05).There were no significant differences between the cervical and intracranial hemodynamics indexes 1 month,6 months,1 a and 2 a after treatment.Two-year follow-up found 4 cases of restenoses after implantation,and the rate for restenosis was 4.2％.Conclusion Carotid artery stent implantation improves significantly cervical and intracranial blood supply as well as CVR of the carotid stenosis patient,and CDFI combined with TCD can be used for the accurate evaluation of the efficacy and postoperative follow-up of carotid artery stent implantation.

[ ABSTRACT] AIM:To develop the cell model of polymer/liquid crystal and to study the effect of their elasticity on the adhesion of rat bone marrow mesenchymal stem cells (rBM-MSCs).METHODS: Using the method of solvent e-vaporation induced phase separation, the cell model of polymer/liquid crystal was constructed.The surface morphology and phase separation structure were determined by polarized optical microscopy ( POM) , scanning electron microscopy ( SEM) and small angle X-ray scattering ( SAXS ) .rBM-MSCs were separated and expanded by adherent culture.The surface markers of rBM-MSCs were detected by flow cytometry.The cells were induced to osteogenic differentiation and adipogenic differentiation for 2 weeks.After 3 passages, the cells were divided into 4 groups, including total PU control group, 10%membrane group, 30%membrane group and 50%membrane group.The cells were then incubated with rhodamine phalloi-din for cytoskeleton staining and were observed under the confocal laser scanning microscope after cultured for 24 h.RE-SULTS:The cell model of polymer/liquid crystal was constructed successfully using the method of solvent evaporation in-duced phase separation.Flow cytometry results showed that the rBM-MSCs positively expressed CD29, CD44 and CD90, and negatively expressed CD34 and CD45.After stained with alizarin red S and oil red O, the calcium nodule and lipid droplets in rBM-MSCs were observed obviously.The cytoskeleton staining result indicated that the area in total PU control group, 10%membrane group and 30%membrane group were greater, and the actin microfilaments were also clearer than
that in 50%membrane group.CONCLUSION:The cell model with suitable content of liquid crystal made a contribution to the rBM-MSCs’ adhesion, but too much liquid crystal inhibits cell adhesion.

ObjectiveTo evaluate the treatment efifcacy of the treatment promotion of standardized management for chil-dren with asthma.MethodsMedical records of 150 children with asthma were reviewed and divided into management group or control group according to whether standardized management was accepted. Comprehensive asthma education for asthma pa-tients and their parents including asthma associated basic knowledge education, health education as well as follow-ups at deifned intervals was conducted in 78 cases. In the meantime, standardized asthma therapies were performed. Control group involved 72 cases who did not receive asthma education managements and only accepted regular clinical therapies. After 1-year observational follow-up, , clinical efifcacy of children with asthma, changes of knowledge-attitude-practice of parents, and compliance of med-ication were compared between the two groups.ResultsAfter promotion of standardized managements treatment, asthma con-trol rates in the management group were signiifcantly higher than that of the control group(χ2=54.68,P<0.01); In addition, the rate of asthma attacks, emergency visits as well as hospitalizations were obviously reduced in the management group than control group (both withP<0.01). Knowledge associated with asthma, therapy and management executions as well as knowledge-atti-tude-practice of parents also demonstrated apparent elevations in the management group (P<0.01); At the same time, management group has illustrated superior medication compliance over the control group (χ2=66.27,P<0.01).ConclusionPromotion of standardized treatment management among children with asthma can help to achieve effective control by raising levels of knowl-edge-attitude-practice of the parents as well as the patient’s compliance to the treatment.
