[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 significance of cyclooxygenase-2 (COX-2),vascular endothelial growth factor(VEGF) protein expression and angiogenesis in hepatocellular carcinoma(HCC).Methods Tissue sec- tions from 40 HCC patients were examined immunohistochemically for protein expression of COX-2 and VEGF.Mi- crovessel density(MVD) was counted by endothelial cells immunostained by anti-CD34 antibody.Results The ex- pression of COX-2 protein in well differentiated HCC was stronger than that in moderately differentiated HCC and poorly differentiated HCC(P

Objective:To investigate the effect of mycophenolate mofetil(MMF)on proliferation and apoptosis of cyst-lining epithelial cells in patients with autosomal dominant polycystic kidney disease(ADPKD),and to compare its effect with that of rapamycin(RAPA)in vitro.Methods: Primary cultured cyst-lining epithelial cells were treated with MMF and RAPA at different concentrations(0,0.005,0.05,0.5,5 ?g/ml)for 48 h or 72 h.The inhibitory effects of them on the cells were evaluated by MTT assay;the cell cycle distribution and apoptotic ratio were determined by flow cytometry.The morphological changes of cyst-lining epithelial cells were observed under transmission electron microscope.Results: Both MMF and RAPA significantly inhibited the proliferation of cyst-lining epithelial cells in a dose-and time-dependent manner.After 48 h treatment,the cells were blocked at S phase by MMF and at G0/G1 phase by RAPA.Both drugs induced cell apoptosis,with the maximal apoptotic rate being(5.53?0.27)% for MMF and(4.36?0.10)% for PAPA.Typical morphological changes of apoptotic cells were observed under electron microscope.Conclusion: MMF can effectively inhibit proliferation and induce apoptosis of cyst-lining epithelial cells,but its inhibitory effect is weaker than that of RAPA.

Objective To establish the animal model with stress ulcer(SU) and probe the relationship between the gastric mucosal injury and lasting stress time,the dynamic structural changes of pH of gastric juice.Methods Twenty-four SD young rats were randomly divided into 4 groups:control group,45 min(groupⅠ),90 min(groupⅡ),3 h(groupⅢ)groups under water immersion restraint stress(WRS).The change of gastric mucosal ulcer index(UI),pH of gastric juice were observed.Results Acute gastric mucosal damage was induced by WRS,with the WRS time prolonged,UI increased gradually and pH of gastric juice remarkably decreased in experimental rats.UI was positively rela-ted with stress time(r=0.957 P

Objective To explore the effects of rhubarb navel therapy on fecal continence in rectal cancer patients with colostomy.Methods 60 patients with colostomy were randomly divided into the experimental group and the control group with 30 patients in each group.Patients in the control group received routine therapy and health education whereas the experimental group received 30-day extra rhubarb navel therapy started on the 15th day after the operation.The two groups were compared in postoperative 3 months with the following factors:the functions of colostomy and the formation of bowel regularity.Results The scores of the scale about the functions of permanent abdominal colostomy were improved in both groups.However,the score in the experimental group was much higher than that in the control group.The number of patients forming bowel regularity in the experimental group was more than that in the control group (19 and 4 cases respectively).Conclusions Rhubarb navel therapy is beneficial to rectal cancer patients with colostomy to improve the functions of colostomy and form the bowel regularity.
