[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.

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.

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.

AIM:To explore a novel method to isolate human nucleus pulposus mesenchymal stem cells (hNP-MSCs) in vitro and to identify their biological characteristics.METHODS:The explant culture method was employed to isolate hNP-MSCs from nucleus pulposus tissue obtained by percutaneous endoscopic lumbar discectomy (PELD).The isolated cells were passaged for purification and cultured in vitro followed by morphological observation.The cell proliferation ability was detected by CCK-8 assay.Growth curves of the cells were drawn and surface antigens were detected by flow cytometry.The cells at the 3rd~6th passages were induced for adipogenic, osteogenic and chondrogenic differentiation, and examined by oil red O staining, alizarin red staining and Alcian blue staining.RESULTS:The cells with self-renewal were obtained from nucleus pulposus tissue obtained by PELD.The results of flow cytometry analysis revealed that the cells were positive for CD29, CD44, CD90, CD73 and CD105, but negative for CD34 and CD45.The proliferative capacity was consistent with the growth characteristics of MSCs and multilineage differentiation potential was identified.CONCLUSION:A novel method to efficiently isolate and culture hNP-MSCs,PELD combined with explant culture method,was established, which would promote the study of regenerative medicine based on hNP-MSCs.

[ 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.

Objective To analyse the clinical and therapeutic features as well as laboratory findings in bullous pemphigoid with non-bullous lesions as initial manifestation. Methods Clinical data on 34 cases of bullous pemphigoid with non-bullous lesions as initial manifestation were retrospectively analyzed. Results The male to female ratio was 1.83 :1, with a mean age of onset at 59.79±15.63 years. Before typical bullae appeared, patients presented with erythema, papules, papulovesicles' plaques" wheals, nodules,or erythema muitiforme-like lesions, with the most common lesions being erythematous papules and plaques (occumng in 35.29% of these patients). Conclusions Among these patients, nearly 1/3 displayed various skin lesions at the onset; simultaneous erythematous papules and plaques are the most common initial manifestation.

[Summary] According to urinary albumin excretion rates ( UAER) , 256 patients with type 2 diabete mellitus (T2DM) were divided into normal albuminuria (NA), microalbuminuria (MA), and clinical nephropathy (CN) groups while 108 healthy subjects as control group. The analysis of variance of single factor was applied to examine lipoprotein(a), triglyceride, total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), cystatin C, and homocysteine. The correlations of lipoprotein ( a ) with urinary albumin excretion rate ( UAER ) and glomerular filtration rate ( eGFR ) were analyzed by Pearson correlation analysis. The sensitivities of lipoprotein ( a ) were evaluated in diagnosis of diabetic nephropathy ( DN) by receiver operating characteristic curve. The results showed that lipoprotein ( a) levels in NA, MA, and CN groups were gradually increased, with a significant increase in CN group(P<0. 05). Pearson correlation analysis revealed that lipoprotein (a) was positively correlated with systolic pressure, TC, cystatin C, and UAER(all P<0. 05) and negatively correlated with fasting blood glucose and eGFR (P<0. 05). The area under the ROC curve of lipoprotein(a) was 0. 639, with the sensitivity 66. 4% and specificity 55. 9% in the optimal cutoff value of 8. 41 mg/dl. These results suggest that lipoprotein(a) may serve as an index for monitoring DN based on its better correlation with UAER and eGFR.

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.
