Enhanced expression of adhesion molecules on human endothelial cells of synovial tissue has been demonstrated in patients with dialysis related amyloidosis(DRA).The study was conducted to elucidate the mechanism by which the expression of adhesion molecules on human endothelial cells was up regulated. Human endothelial cells derived from umbilical veins(HUVEC) were coincubated in vitro with native human serum albumin(HSA) or HSA modified with advanced glycation end products(AGE HSA).The expression of adhesion molecule intercellular adhesion molecule 1(ICAM 1),vascular cell adhesion molecule 1(VCAM 1) and E selectin was determined respectively by immunofluorescence staining and flow cytometer analysis.The results showed that ICAM 1 and VCAM 1, but not E selectin,were constitutively expressed on HUVEC. AGE HSA enhanced the expression of ICAM 1, VCAM 1 and E selectin on HUVEC in a time and dose dependent manner. HSA had no effect on the expression of adhesion molecules. The results led to the conclusion that AGE HSA up regulated the expression of adhesion molecules on human endothelial cells and therefore promoted the infiltration of monocytes/macrophages around ? 2 microglobulin amyloid.

OsRacD belonging to rice Rho family of the small GTP binding proteins,is a pivotal gene involved in rice photoperiod fertility conversion of photoperiod sensitive genic male sterile rice,which influences rice fertility via controlling the pollen tube growth.T20N site-directed mutation was introduced into its highly conserved G1 motif by PCR-mediated method to mimic its GDP-binding state based on the sequences alignment and conserved domains analysis.The prokaryotic expression vector of OsRacD and T20N-OsRacD were constructed,and the His6 tag fused proteins were expressed and purified from E.coli.After identified by Western blot,the GTP hydrolysis activities were detected.The results showed that the GTPase activities of T20N-OsRacD were significantly reduced comparing with that of OsRacD,suggested that OsRacD and T20N-OsRacD have different biochemical characteristics.

AimTo find out the comprehensive strength and trends in scientific research area,and to provide foundation for decision-making on pushing the paediatric research forward,we reviewed the achievements of the scientific papers publication and the professional background of the authors between 2001 and 2010. Methods We extracted data and described the distribution characteristics of the paper publication amount,degree in the 10 years,as well as age,construction of professional and technical title,the education qualification of the authors. Moreover,we statistically analyzed the variability of the publication conditions within statistical source journals among the authors with different technical title.ResultsThe amount of paper publication increased anually in the 10 years,but with few published in statistical source journals,and the core authors group have not formed yet.Meanwhile,the general internal medicine maintained the dominant propotion.Authors aged 30 -50 years old,with middle technical title and with bachelor degree published the majority of the papers.The propotion of the papers published in statistical source journals and in the Zhonghua series medical journals were significantly higher in authors with master degree and above.ConclusionsIn order to construct a stable core authors group and increase the amount of the paper publication,we should continue to encourage those author groups with high output rate and make greater support on the potential authors.Furthermore,we must take more effort on impoving publication quality in the future.

Objective To establish the quality standards of Longdan Xiegan Capsule and Longdan Xiegan Soft Capsule. Methods Gentianae Radix et Rhizoma, Bupleuri Radix, Scutellariae Radix, Gardeniae Fructus, Alismatis Rhizoma, Angelicae Sinensis Radix, Rehmanniae Radix and Glycyrrhizae Radix et Rhizoma were identified by TLC. Gentiopicrin in Gentianae Radix et Rhizoma, geniposide in Gardeniae Fructus, baicalin in Scutellariae Radix were determined by HPLC. Results The TLC spots developed were clear. Gentiopicrin showed good linear relationship in the range of 0.066 1-0.595 1 mg (r=1.000 0), the average recovery of Capsule was 99.34%(RSD=1.50%), and the average recovery of Soft Capsule was 96.62%(RSD=1.50%). Geniposide showed good linear relationship in the range of 0.076 1-1.369 8 mg (r=0.999 9), the average recovery of Capsule was 101.3% (RSD=1.70%), and the average recovery of Soft Capsule was 100.59%(RSD=0.79%). Baicalin showed good linear relationship in the range of 0.214 4-1.608 mg (r=1.000 0), the average recovery of Capsule was 101.12% (RSD=1.30%), and the average recovery of Soft Capsule was 98.07% (RSD=2.40%). Conclusion The method is simple and reproducible. It can be used to control the quality of Longdan Xiegan Capsule and Longdan Xiegan Soft Capsule.

The infection of HBV may cause acute and chronic hepatitis B,and potentially lead to hepatocirrhosis and liver cancer.As a defense mechanism of organism to resist external infection,RNA interference(RNAi) has become a powerful tool for us to study its effects on antiviral infection and gene therapy in recent years.In this article we summarize the mechanisms of RNA interference and the progress on anti-HBV infection studies by RNAi.

Objective To investigate the outcome of free posterolateral leg perforator flap in the reconstruction of soft tissue defects of oral and maxillofacial area.Methods From February,2014 to August,2016,16 patients were performed defect reconstruction following oral cancer ablation with free posterolateral leg perforator flap including 3 cases of sequamous cell carcinoma of the tongue,6 cases of carcinoma of the buccal mucosa,7 cases of sequamouse cell carcinoma of the floor of mouth.The flap ranged from 5.0 cm×3.0 cm to 13.0 cm ×9.0 cm in size,and were adjected to the soft tissue defects of oral and maxillofacial area.The outcome of reconstruction was evaluated by considering the facial appearance,the swallowing and the speach function,the ranges of mouth opening and patient prognosis.Results All 15 transplanted flaps survived well and only 1 survived after disposing in time,because of vascular crisis.The donor sites were closed directly without donor-site morbidity.All patients were satisfactory with their facial appearance,the ranges of mouth opening and swallowing and speech function.Conclusion The free posterolateral leg perforator was an ideal free tissue for repairing functionally oral and maxillofacial defects,sinceit including some beneficial characteristic such as constant blood vessel,flexible and divese design,abundant and position-latent donor site tissues,small operation loss,flexible preparation and loss of major vascular nerves.
