[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 study the protective effect of total flavones of hawthorn leaf (TFHL) on renal ischemia/reperfusion (I/R) in rats.Methods A model of renal I/R was made by clamping double renal pedical for 60 min and reperfusion for 24 h.TFHL (30 or 60 mg/kg) was injected before clamping renal ischemia. The level of serum urea nitrogen(BUN), serum creatinine(Scr), tumor necrosis factor-?(TNF-?),interleukin-1(IL-1) in serum were detected after reperfusion for 1 and 24 h,respectively,and the level of malonaldehyde (MDA) and erythrocuprein (SOD) in renal tissues were measured after reperfusion for 24 h.Results TFHL significantly decreased the level of BUN and Scr, decreased the concentration of TNF-? and IL-1 in serum. Pretreatment with TFHL also enhanced the activity of SOD reduced the concentration of MDA in renal after I/R.Conclusions TFHL has significantly protective effect on renal I/R and markedly improve the renal function. The mec-hanisms are associated with decreasing the lipid peroxidation reaction and reducing the level of TNF-? and IL-1.

Background Excimer laser corneal refractive surgery is one of the major methods to correct refractive error.Centration of the ablation zone is an important factor that affects visual quality after surgery.The pupil center and its shift is a major factor to determine the ablation center.Therefore further study on pupil centroid shift with illumination level alteration is needed.Objective This study aimed to study the characteristics of the pupillary centroid shift along with the change of pupil size under the different illumination conditions and the possible clinical application of the curve of pupillary centroid shift in exeimer laser corneal refractive surgery.MethodsThe variation of pupil size induced by illumination and the changes of pupil center were measured on 114 moderate myopia eyes of 57 subjects with Astra MaxTM Corneal Topographer.Illumination of placido target and image snap model of the topographer was customized to provide 5 illumination levels as follows:0.8,4.4,18.9,82.3,355.0 Lx.Vectorial analysis was used to graph the change of pupil center related to the Coaxially Sighted Corneal Reflex (CSCR).Raw data is converted to relative value to analyze the pupiilary centroid shift.The mean relative change of the pupil size(△P)and the mean of relative pupillary centroid shift(△C)in the form of percentage were used to attenuate the variation among subjects.The original value of illumination(darkest)is defined as 0％ and maximum value(lightest)was as 100％.Results With the increase of illumination,the shift of the pupil center towards nasal side when pupil constrict was found.The mean change of pupil size under the 5 illumination levels were 0,(1.28 +0.40)mm,(2.34 ±0.53)mm,(3.34+0.54)mm,(4.03 ±0.56)mm respectively,and the △P values was 0％,32％,58％,83％,100％ respectively.The mean of pupil centroid shift under the 5 illumination levels were 0,(78±33)μm,(116±60)μm,(143 ±66)μm,(170±71)μm respectively,and the △C was 0％,46％,68％,84％,100％respectively.There was a linear relation between the relative pupil centroid shift and the relative change of pupil size (r=0.980,P=0.025).The amount of pupil centroid shift has a positive correlation with amplitude of the change of pupil size(r=0.480,P＜0.01).Conclusion Pupil center shifts with the change of pupil size.The linear relation between relative pupil centroid shift and the relative change of pupil size can be applied in eximer laser corneal refractive surgery to improve the visual quality with customized ablation center location.

Objective:To improve the safety,rationality and efficacy of medication for ovarian cancer patients complicated with cirrhosis by the participation of clinical pharmacists in the therapy. Methods:Clinical pharmacists participated in the therapy for an ovarian cancer patient with cirrhosis,and provided a rational and individualized therapeutic regimen through the drug experience of clinical pharmacists as well as the relevant medical guides and literatures. Results:The therapeutic efficacy was increased by the participation of clinical pharmacists in the therapy,the potential risk of the chemotherapy was avoided and the security of medication was assured. Conclusion:The participation of clinical pharmacists in therapeutic practice can improve the normalization of pharmacotherapy for ovarian cancer patients with cirrhosis,which also can provide ideas and methods for treating the similar patients.

Objective To investigate the existence of the erythropoiesis inhibitors(?).Methods Twelve patients suffered from uremia with anemia were studied[5 males,and 7 females,(50?12)years].Methylcellulose culture technique was used to culture mice bone marrow cells.The sera from the uremia patients were added to CFU- E and BFU-E culture medium with final concentrations of 1,25%,2.5% and 5%,Mice bone marrow cells were ob- tained from the female Balb/c mice.In vitro CFU-E and BFU-E culture in the presence of sera from uremia patients was compared with that in the presence of normal human subjects with the use of normal mice bone marrows.Re- suits The effects of the sera from uremia patients on CFU-E and BFU-E colon growth were in a dose-dependent manner.The effect was correlated with the concentrations of the sera(P

Objective To explore the relationship of hydrogen sulfide (H2S) and the extracellular matrix of the diabetic nephropathic rats' glomerulars.Methods Twenty-one male rats(Sprague-Dawley) were randomly divided into Control group(n =7),DN group (n =7) and DN + H2 S group (n =7).Diabetes was induced in the rats except Control group rats by STZ (60mg/kg).The rats of the DN + H2S group were injected with NaHS every day,and rats of other groups were injected with NS.Eight weeks later,three groups were compared in proteinuria of 24 hours,KW/BW,the proportion of the BrdU positive cell and the distribution of α-SMA in glomerulars.Results Compared with Control group,DN group rats were significantly increased in proteinuria of 24 hours and KW/BW (P ＜ 0.01).Kidney biopsy in DN groups rats were typical DN pathological manifestation.In treatment with NaHS,the DN rats in the DN + H2S group were decreased in proteinuria of 24 hours,KW/BW,the proportion of the BrdU positive cell and the distribution of α-SMA in glomerulars (P ＜ 0.01),and was similar with the control group in the pathology of renal.Conclusion The H2 S control the multiplication of myofibroblast,and were decreased in the distribution of α-SMA in glomerulars.The H2S treatment may put off the progress of the extracellular matrix in the DN rats' glomerulars.

Microvesicles (MVs) are the heterogeneous mixtures of vesicles. MVs released by leukemia cells constitute an important part of the leukemia microenvironment. MVs might act as important reservoirs of microRNAs (miRNAs). It is worth evaluating whether MVs possess some unique miRNA contents that are valuable in understanding the pathogenesis. In this study, we investigated the miRNA expression patterns of Nalm-6-derived MVs, Jurkat-derived MVs and normal cell-derived MVs using miRNA microarrays. The potential target genes regulated by differentially expressed miRNAs were also predicted and analyzed. Results demonstrated that 182 miRNAs and 166 miRNAs were differentially expressed in Nalm-6-MVs and Jurkat-MVs, respectively. Many oncogenes, tumor suppressors and signal pathway genes were targeted by these aberrantly expressed miRNAs, which might contribute to the development of B-ALL or T-ALL. Our findings expanded the potential diagnostic markers of ALL and provided useful information for ALL pathogenesis.
