AIM: To observe anti inflammatory, anti bacterial and immune regulation effects of shuyanling soft capsule. METHODS: The dimethylbenzene induced the degree of ear swelling in mice and turpentine induced proliferation in rats were used to observe the anti inflammation effects of shuyanling soft capsule. The anti bacterial effects were observed both in vitro and in vivo. The immune regulation effects were studied by the splenocyte proliferation response, the activity of antibody producing cells and the phagocytosis of leukocyte in mice. RESULTS: Shuyanling soft capsule inhibited dimethylbenzene induced the degree of ear swelling in mice and turpentine induced proliferation in rats, protected the mice from the infections of staphylcoccus aureus and salmonella typhi, and repressed sixteen kinds of bacterium in vitro. Furthermore, the capsule remarkably enhanced the phagocytosis of neutropil and increased the activity of spleen antibody producing cells and the transformation of the T and B cell in spleen in mice. CONCLUSION: Shuyanling soft capsule has anti inflammatory, anti bacterial and immune regulation effects.

Objective To estimate the influence of 1,25(OH)2D3 on the proliferative ability of and methylation levels of genomic DNA and proliferation-associated gene promoter in human HaCaT keratinocytes.Methods Some cultured HaCaT cells were treated with 1,25 (OH)2D3 of 10-6,10-7 and 10-8 mol/L for 24 hours,then,methyl thiazolyl tetrazolium (MTT) assay was carried out to evaluate the proliferative activity of cells,and a global DNA methylation quantification kit was used to determine the global DNA methylation level.Real-time PCR was conducted to quantify the mRNA expression of DNA methyl transferases (DNMTs) and methyl-DNA binding domain (MBD) proteins,and methylation-specific PCR (MS-PCR) to evaluate the methylation status of promoter region in the programmed cell death 5 (PDCD5) and tissue inhibitor of metalloproteinase 2 (TIMP2) genes,in HaCaT cells after 24-hour treatment with 1,25 (OH)2D3 of 10-6 mol/L.The HaCaT cells receiving no treatment served as the control.Results Compared with the untreated HaCaT cells,those treated with 1,25(OH)2D3 of 10-6 mol/L showed significantly down-regulated proliferative activity (0.152 ± 0.027 vs.0.290 ± 0.017,P < 0.01),global DNA methylation level (0.187 ± 0.071 vs.0.316 ± 0.049,P < 0.05),DNMT3a and DNMT3b mRNA expression levels (P < 0.01 or 0.05),but markedly upregulated mRNA expression levels of MECP2,MBD2,PDCD5 and TIMP2 (P < 0.01 or 0.05).Moreover,the DNA methylation levels within the promoter region of PDCD5 and TIMP2 genes were significantly lower in HaCaT cells treated with 1,25 (OH)2D3 of 10-6 mol/L than in the control cells (0.38 ± 0.135 vs.0.72 ± 0.121,0.46 ± 0.172 vs.0.68 ± 0.133,both P< 0.05).Conclusions 1,25(OH)2D3 may down-regulate the global genomic DNA methylation level of,and modulate the expression of DNA methylationmodifying genes in,HaCaT cells.Furthermore,1,25 (OH)2D3 can decrease the promoter methylation levels but induce the overexpression of PDCD5 and TIMP2 genes,and decelerate the proliferation of HaCaT cells.

OBJECTIVETo investigate the effects of external fixation combined with minimally invasive internal fixation for the treatment of distal radial fracture and dislocation of type IV based on Fernandez classification.
METHODSFrom January 2007 to October 2012,19 patients with the distal radius fracture and dislocation of type IV according to Fernandez classification were reviewed. There were 14 males and 5 females,ranging in age from 22 to 42 years old,with an average of 36.5 years old. All the patients were treated with minimally invasive reduction, and external fixation with finite internal fixation. The K-wire was used to fix radiolunate articular surface for correcting the instability of dorsal and volar intercalated segment. The radiolunate angle, scapholunate angle, and the length of the radial shorting were measured by the standard X-ray. Gartland and Werley evaluation system was used to evaluate recovery of function.
RESULTSNo complications such as injury of blood vessels and radial nerves and pin track infections occurred. After operation, the radiolunate angle, scapholunate angle and the length of the radial shorting time were (9.5 +/- 3.3) degrees, (51.3 +/- 11.2) degrees and (11.2 +/- 1.8) mm by the standard X-ray. On the 3rd month after operation, GW score was 3.02 +/- 3.05. There was no re-displacement and subluxation occurred during the follow-up period. Good functional recovery were improved wrist function significantly.
CONCLUSIONExternal fixation combined with minimally invasive internal fixation can treat distal radial fracture and dislocation of type IV based on Fernandez classification. Wrist joint stability depends on the structure of the bone and ligament around wrist joint. Emphasis on the diagnosis and treatment of carpal instability, and postoperative functional rehabilitation can improve wrist function.
