The effects of sodium salicylate on the expression of heat shock protein 27 (HSP27) during oxidative stress in tissue-cultured human lens epithelial cells were investigated. Cultured human lens epithelial cells (HLB-3) were divided into 3 groups: control group (group A), oxidation injury group (group B) and sodium salicylate group (group C). Apoptosis of human lens epithelial cells cultured in vitro was induced in the presence of 150 micromol/L H2O2. Cells viability and the expression of HSP27 were analyzed. Viability of the cells was measured by methyl thiazole tetrazolium (MTF) chromatometry. The expression of HSP27 in HLB-3 cells was detected by using immunohistochemistry and image analysis system. Sodium salicylate could induce the expression of HSP27, and the cells viability in group C was significantly higher than in group B (0.2667+/-0.01414 vs 0.2150+/-0.01080, P=0.012<0.05). The average gray value of HSP27 in group B was less than that in group C (P=0.000<0.05). The increased expression of HSP27 by sodium salicylate might play an important role in the protection of hydrogen peroxide-induced injury of human lens epithelial cells, suggesting that sodium salicylate could suppress, at least in part, the apoptosis of human lens epithelial cells.

OBJECTIVETo investigate the clinical efficacy of cannulated screw fixation with percutaneous Poking reduction for the treatment of Sanders II, III calcaneal fracture.

METHODSFrom January 2012 to January 2014, 19 patients with Sanders II, III calcaneal fracture were treated with cannulated screw fixation with percutaneous Poking reduction. There were 14 males and 5 females, ranging in age from 19 to 58 years old, with an average age of (38.3 +/- 4.1) years old. The changes of Bohler angle and Gissane angle were measured and compared preoperatively and postoperatively to observe the recovery of the articular surface. The Maryland Foot Score was used to evaluate operation outcomes.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 28 months with a mean of (22.3 +/- 5.3) months. The Bohler angle and Gissane angle were improved significantly after operation compared with those before operation (P < 0.05). The Maryland score was 83.2 +/- 8.4.

CONCLUSIONTreatment of calcaneal fractures with screw fixation with percutaneous Poking reduction has several advantages such as satisfactory outcome,less damage, fewer complications, quicker recovery, and shorter hospital stay,and it is one of the effective treatments for Sanders II and III calcaneal fractures.

The somatostatin analogue pasireotide is a new type of protein which is the first therapeutic agent targeted to the pituitary.Pasireotide can prevent adrenocorticotropic hormone release and inhibit the growth of tumor cells after coupling with somatostatin receptor of the target cell membranes.Pasireotide has a high binding affinity for most of somatostatin receptor (SSTR) subtypes and in particular for SSTR5.Pasireotide can paly an important role in the new round of new targets for individualized diagnosis and treatment of tumors through the studies of translational medicine.

BACKGROUND:Rheumatoid arthritis is a common chronic systemic autoimmune disease which is characterized by synovial lesions and bone erosion. The clinical treatment is stil a difficulty.
OBJECTIVE:To explore the effect of exogenous hydrogen sulfide on the articular lesions in rheumatoid arthritis rats.
METHODS:Sprague-Dawley rats were divided into four groups:control group, model group, high concentrations of hydrogen sulfide intervention group, low concentrations of hydrogen sulfide intervention group. At 2 and 4 weeks after intervention, the arthritis index, levels of serum inflammatory cytokines (tumor necrotic factor-αand interleukin-1β), pathological change of synovial tissue, average absorbance of knee joint specimens using col agen-II immunohistochemical staining were measured.
RESULTS AND CONCLUSION:The arthritis index, levels of serum inflammatory cytokines and inflammatory infiltration of synovial staining in the model group and two intervention groups were higher than that in control group, the high concentrations of hydrogen sulfide intervention group was significantly higher than the model group (P<0.05) while the low concentrations of hydrogen sulfide intervention group was lower than the model group (P<0.05). The average absorbance of knee cartilage specimens using col agen-II immunohistochemical staining was lower in the model group and two hydrogen sulfide intervention groups compared with the control group, the high concentrations of hydrogen sulfide intervention group was significantly lower than the model group (P<0.05) while low concentrations of hydrogen sulfide intervention group was higher than the model group (P<0.05). Hydrogen sulfide has a regulatory effect on rheumatoid arthritis, high concentrations of hydrogen sulfide aggravate arthritis and cartilage degradation, low concentrations of hydrogen sulfide reduce arthritis and protect cartilage.
