Objective To explore the change of thyroid hormones and leptin at hyperuricemia (HUA)/gout.Methods A total of 96 primary gouts,65 HUAs,and 59 healthy examiners was selected.Height,weight,blood pressure,renal function,serum uric acid(SUA),glucose,lipid profiles,insulin,thyroid hormones were measured after an overnight fast.Results (1) The prevalence of subhypothyriodism at gout and HUA was 7.29％ and 15.38％,respectively.They were higher than that at healthy subjects.(2) Body mass index (BMI),systolic blood pressure (SBP),triglyceride (TG),cholesterol (CHO),thyroid stimulating hormone (TSH),fasting insulin (FINS),homeostasis model assessment of insulin resistance (HOMA-IR),and serum leptin level were increased remarkably at gout/hyperuricemia relative to control group,whereas,free thyroid hormone (FT4) was decreased.(4) In the gout and hyperuricemia groups,TSH was used as the dependent variable for the linear multivariate regression analysis,the results showed that sex,age,BMI,SUA,FT4,HOMA-IR,and Leptin were included in the regression equation of TSH (βwere-0.27,0.832,0.946,0.198,-0.942,0.895,and 0.650,respectively).Conclusions The prevalence of subhypothyroidism in primary gout/hyperuricemia was increased.Female,age,BMI,SUA,FT4,HOMA-IR,and leptin were the independent risk factors.Insulin resistant and leptin played the media roles in the gout/HUA and hypothyroidism.

Objective To observe the effects of liver-discharging and stomach-harmonizing therapy on quality of life in senile patients with reflux esophagitis and to evaluate the therapeutic effect of traditional Chinese medicine (TCM) on chronic diseases. Methods Sixty patients with senile reflux esophagitis selected from in-patients and out-patients of Henan Province Hospital of TCM from March 2012 to October 2013 were randomly divided into experimental group and control group(each,30 patients). The experimental group was treated with Xiaoyao powder (its ingredients could be added or subtracted according to the patient's individual situation)combined with omeprazole and domperidone,while in the control group,only western drugs,omeprazole and domperidone were applied. The therapies in both groups lasting for 8 weeks constituted one therapeutic course. The MOS 36-item short form healthy survey(SF-36)was used to evaluate the degree of improvement of patients,quality of life,and clinical effects and adverse drug reaction were observed. Results The total scores of SF-36,physical and mental health scores of both groups were increased significantly,and the degree of elevation in scores in the experimental group was markedly higher than that in the control group(total scores of SF-36:124.2±11.5 vs. 117.1±10.9,physical health scores:67.9±5.3 vs. 62.9±6.2,mental health scores:56.1±6.7 vs. 55.0±6.6,all P<0.05). The total effective rate of experimental group was much superior to that of control group(96.7%vs. 80.0%,P<0.05). No obvious adverse reactions happened in the two groups. Conclusion Liver-discharging and stomach-harmonizing therapy can improve the quality of life in aged patients with reflux esophagitis.

Objective: To evaluate the adaptation of different materials for gingival layer in Class Ⅱrestorations using Micro-CT.Methods:Eighteen extracted human premolars were selected, and ClassⅡcavities were prepared.The teeth were randomly divided into six groups and restored using layering tech-nique.Six materials were used for gingival layer, including four injectable materials:Beautifil Flow Plus F00 (F00), Beautifil Flow F10 (F10), Filtek Z350 Flowable (Z350F), FujiⅡLC CAPSULE (Fuji), and two packable materials: BeautifilⅡ (BF), Filtek Z350 (Z350).The restored teeth were scanned with micro-CT and the images were 3D reconstructed to evaluate the volumes and the distribution of the voids on the restoration-tooth interface of the gingival layer.The volume of the voids were statistically analyzed using nonparametric Jonckheere-Terpstra tests.Results: The volumes ( mm3 ) of the voids on the restoration-tooth interface were: Z350F (0.000 15), F10 (0.000 39), F00 (0.012), Fuji (0.070), Z350 (0.16) and BF (0.20).There were significant differences between Z350F/F10 and Fuji/Z350/BF (P<0.05).Most of the voids were found on the point-line angles of the cavities.Con-clusion:The voids on the restoration-tooth interface were mainly on the point-line angles of the cavities. Injectable materials with high flowablility could reduce the restoration-tooth interface voids significantly when used for the gingival layer in ClassⅡrestorations.

Objective To investigate the role of C-Jun N-terminal kinase (JNK) in epithelial mesenchymal transition (EMT) induced by transforming growth factor β1 (TGF-β1) in rat peritoneal mesothelial cells(RPMCs). Methods RPMCs were harvested from the peritoneum of male Sprague-Dawley rats, then cultured in DMEM/F12 medium with 15% (V/V) FBS. After stimulation with TGF-β1, the expression of a-smooth muscle actin (α-SMA), E-cadherin and collagen I were detected in RPMCs. In some groups, the ceils were pretreated with SP600125, a specific inhibitor of JNK, for 4 hours before incubation with TGF-β1. The protein expression of phosphorylated JNK was detected by Western blotting. The mRNA and protein expression ofα-SMA, E-cadherin and collagen I were examined with RT-PCR and Western blotting, respectively.The intracellular distribution and expression of α-SMA was determined by indirect immunofluorescence. Results TGF-β1 could significantly increase the expression of α-SMA and collagen I, and decrease the expression of E-cadherin in RPMCs. TGF-α1 could stimulate the expression of phosphorylated JNK at 5 minutes with the peak at 10 minutes (P<0.01). The addition of SP600125 effectively inhibited TGF-β1-induced high expression of α-SMA and collagen I (P<0.05), and prevented TGF-β1-induced down-regulation of E-cadherin expression in RPMCs (P<0.05). The indirect immunofluorescence showed that the expression of intracellular α-SMA in RPMCs stimulated by TGF-β1 for 48 h increased significantly, which could be inhibited by SP600125. Conclusions JNK regulates epithelial mesenchymal transition induced by TGF-β1 in rat peritoneal mesothelial cells. JNK inhibitor may be used as a novel therapeutic agent for peritoneal fibrosis.

To look for new genes from human brain, get a fragment was obtained using adaptor primer and 3' anchor polymerase chain reaction (PCR) with the human adult whole brain cDNA as template. The fragment was cloned into T easy vector and automatically sequenced with 310 Genetic Analyzer. Later the whole length cDNA of this novel gene was got with the method of 3'rapid amplification of cDNA end (RACE). The whole length of cDNA of this novel gene is 2 024 bp. Chromsome location is at 14q11.2 including 16 extrons and 15 introns. After scanning the sequence against GenBank it is proved that the sequence is a new one. ORF analysis showed that there is a complete coding region in it,it can interprate a protein containing 357 amino acid residules. ProDom analysis result showed that there is an acyl carrier protein (ACP) like domain in it. The gene was banked into GenBank. Then, a pare of primers were designed and were used to amplify the coding region and cloned into pGEX-4T1 expressing vector to express it in E. coli . The Dot blotting and Northern blot showed that this novel gene is highly expressed in the normal adult human brain.

Aim To screen peptides binding specifically to anti-human PTA1mAbs from a random twelve-peptide phage-disp-layed library. Methods Series of PTA1mAbs(LeoA1、 1B11、 C9、 2D1、 2E9、 2G8、 2H2 and E8)were purified using protein-A affinity column. PTA1mAbs which could bind PTA1-Fc fusion protein binding to its ligand were confirmed by flow cytometry, and then used as target to screen phage library. After three rounds of affinity screening, the peptide sequences of positive phage clones were determined and analyzed. Results LeoA1 could block PTA1-Fc fusion protein binding to its ligand. 13 phages which could bind specifically to LeoA1 were isolated from phage library and further confirmed by ELISA. Conserved motifs were found among the sequences of the peptides. Conclusion It was shown that the conserved motifs were candidafe regions binding to PTA1 ligand,which is important to identify functional epitopes for seeking ligand of PTA1 and further investigation of biological function of PTA1.

AIM: To observe the effects of miR-542-5p on the proliferation of rat small intestine crypt epithe-lial IEC-6 cells induced by sphingosine-1-phosphate (S1P).METHODS: Two IEC-6 cell lines (SphK1-IEC-C1 and SphK1-IEC-C2) were established, which expressed sphingosine kinase-1 (SphK1) stably.Radioactive tracer was used to detect SphK1 activity and S1P secretion.The cell proliferation was observed by cell counting and described by drawing growth curve, and the cell cycle analysis was carried out by flow cytometry.The level of miR-542-5p was evaluated by RT-qPCR.RESULTS: Compared with control vector cells without SphK1 cDNA, both SphK1-IEC-C1 and SphK1-IEC-C2 cell lines showed that Sphk1 was elevated, both intracellular and extracellular S1P increased dramatically, the rate of cell growth was faster, the percentage of the cells in S phase increased, and miR-542-5p expression decreased.S1P (0.5~10 μmol/L) led to the decrease in miR-542-5p expression.On the contrary, SphK1 silencing resulted in the increase in miR-542-5p expression in the IEC-6 cells.The miR-542-5p was elevated in SphK1-IEC-C1 cells and SphK1-IEC-C2 cells, which caused the decrease in the percentage of the cells in S phase.The cell growth rate in the above-mentioned 2 cell lines decreased compared with negative control group.CONCLUSION: In IEC-6 cells, S1P promotes proliferation by inhibiting miR-542-5p expression, which induces the cell cycle transferring from G1 phase to S phase.
