Aim To explore the effect and mechanism of resveratrol (Res) on proliferation and differentiation of murine 3T3-L1 preadipocytes.Methods 3T3-L1 preadipocytes were cultured and treated with resveratrol in different dosages.Cell proliferation was analyzed by WST-1 method. Oil red O staining method and spectrophotography were applied to analyze the degree of differentiation. Real-time PCR was applied to detect the mRNA expression of adiponectin and leptin. Western blot was applied to detect the expression of silent information regulator 1 (Sirt1),peroxisome proliferator activated receptor γ (PPARγ) and CCTTA enhancer binding proteinα (C/EBPα).Results Res inhibited proliferation of murine 3T3-L1 preadipocytes in a time-dose dependent manner.The expression levels of adiponectin and leptin mRNA were decreased, and Res also inhibited 3T3-L1 preadipocytes to differentiate into mature adipocytes. Res increased the expression levels of Sirt1 and decreased the expression levels of PPARγ and C/EBPα.Conclusions Resveratrol can inhibit the proliferation and differentiation of 3T3-L1 preadipocytes.The underlying mechanisms may include enhancing expression of Sirt1 and inhibiting expression of PPARγ,C/EBPα which are related to cell differentiation.

OBJECTIVETo study measurement methods of acromioclavicular and coracoclavicular ligament injuries,its therapeutic effects and complications during internal fixation operation for the treatment of fresh acromioclavicular joint dislocations of Tossy type III.

METHODSFrom July 2003 to May 2012,127 patients with acromioclavicular joint dislocations of Tossy type III were treated with wire fixation from coracoid process to clavicle or hook-plate fixation. The patients were divided into group A (63 cases) and group B (64 cases) according to whether acromioclavicular ligament and coracoclavicular ligament were repaired or not. In group A (ligaments repaired), there were 39 males and 24 females with an average age of (33.25 +/- 8.46) years old (ranged from 17 to 59 years). And in group B (no ligaments repaired), there were 41 males and 23 females with an average age of (34.10 +/- 7.19) years (ranged from 19 to 57 years). The operation times, intraoperative blood loss, postoperative infections, internal fixation failure, recurrence and other complications, together with therapeutic effects were compared between two groups.

RESULTSThe outcome was analyzed according to Karlsson standard. In group A, 54 patients got an excellent result and 9 good according to Karlsson standard;the average operative time was (55.90 +/- 26.56) min; the average intraoperative bleeding amount was (99.80 +/- 50.30) ml; 1 patient had wire broken without re-dislocation at 16 weeks after operation, 3 patients got wound fat liquefaction and recovered after treatment, 1 patient had pain after shoulder joint motion and pain disappeared after implants were taken out. In group B, 52 patients got an excellent result and 12 good according to Karlsson standard; the average operative time was (49.50 +/- 23.14) min; the average intraoperative bleeding amount was (87.30 +/- 46.41) ml; 2 patients got wound fat liquefaction, and 2 patients had pain after shoulder joint motion. All the patients were followed up, and the duration ranged from 9 to 16 months. All internal steel-wire or hook plate were taken out during 4 to 9 months without acromioclavicular joint re dislocation. There were no significant difference in the average operative time, the average intraoperative blood less, complication recurrence rates of fixation failure, wound fat liquefaction, postoperative infection, acromioclavicular joint re-dislocation, and therapeutic effects between two groups.

CONCLUSIONBoth wire and clavicular hook plate fixation, performed for fresh acromioclavicular joint dislocation with Tossy type III, are simple, effective, less invasive method with less blood loss. In addition, the treatment without ligaments repaired could not increase incidence of complications.

AIMIn order to explore the mechanism of central motilin-induced feeding behavior, the effects of erythromycin, a motilin receptor agonist, on glucose responsive neurons in hypothalamus were observed.

METHODSExtracellular recordings were made from single neurons in region of lateral hypothalamic area (LHA) and ventromedial hypothalamic nucleus (VMH) in anesthetized rats. On the basis of their responsiveness to intracarotid injection of 0.58 mol/L glucose solution 0.2 ml, glucose-sensitive neurons (GSNs) in LHA and glucoreceptor neurons (GRNs) in VMH were recognized. Effects of intracerebroventricularly (i. c. v.) administration of 4 microg erythromycin on neural activities of glucose responsive neurons and non-glucose responsive neurons were examined. The mixture of EM and GM-109 1 microl were used to GSNs and GRNs which were sensitive to i. c. v. administration of EM.

RESULTSIn LHA, EM increased activity of GSNs significantly (P < 0.05 vs non-glucose-sensitive neurons group). Whereas in VMH, EM significantly decreased the activities of GRNs (P < 0.01 vs non-glucoreceptor neurons group). The mixture of EM and GM-109 had no effect on GSNs and GRNs.

CONCLUSIONEM, a motilin receptor agonist, can stimulate GSNs in LHA and suppress GRNs in VMH and this may contribute to central motilin's effect on feeding behavior.

Until the recent emergence/re-emergence of human-pathogenic viruses in ticks, tick-borne viruses have been neglected as causative agents of human disease (particularly in China). To gain insight into the diversity of tick-borne viruses in Xinjiang Uygur Autonomous Region (northwestern China), we conducted illumina deep sequencing-based screening for virus-derived small RNAs in field-collected Ixodes persulcatus ticks. We found 32, 631 unique virus-matched reads. In particular, 77 reads mapped to the tick-borne group within the genus of Flavivirus, and covered 3.8%-2.4% viral genomes. In addition, 32 unique reads were specific to the Siberian subtype of tick-borne encephalitis viruses (TBEV-Sib) which have never been reported in Chinese TBE loci. We confirmed the potential existence of TBEV-Sib by amplification (using reverse transcription-polymerase chain reaction) of genomic fragments from the envelope gene or 3' genomic terminus from the pools of examined ticks. Both sequences demonstrated high homology to TBEV-Sib strains attached geographically to southern Siberia with nucleotide identity of 97.2%-95.5% and aminoacid identity of 99.4%-98.3%, respectively. In conclusion, we report, for the first time, detection of TBEV-Sib in the natural TBE loci of China. These novel data may provide genetic information for further isolation and epidemiologic investigation of TBEV-Sib.

Objective To examine loss of heterozygosity (LOH) and microsatellite instability (MSI) of locus D8S532 on chromosome 8 and their influence on the expression of sFRP1 in the hepatocellular carcinoma (HCCs), which may provide an experimental evidence for clarifying the mechanism of sFRP1 gene and tumor development. Methods DNA was extracted from formalin-fixed paraffin-embedded tissues. Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and ordinary silver stain were used to study LOH and MSI of locus D8S532. Envision immunohistochemistry, Leica-Qwin computerized imaging system and Image-Pro PluS (IPP) version 4.5 professional imaging analysis software were used to assess the expression of sFRP1. Results The detection rates of LOH and MSI of locus D8S532 in the 36 specimens of HCC were 11.11% and 8.33% respectively. The down-regulation of sFRP1 was observed in 31 of 36 HCCs (86.11%) compared with non-carcinoma liver tissues, and the positive rate of sFRP1 protein of the HCCs was 52.78%( 19/36 ). The frequency of LOH was lower in the cases with positive expression of sFRP1 protein than those negative (0 vs 23.53%, P <0.05). Conclusion It was a common phenomenon that expression of sFRP1 protein is negative or low in Chinese with HCCs. The genetic instability of sFRP1 gene was one of causes, which lead to HCCs. LOH may play a major role in negative expression of sFRP1.
