OBJECTIVETo explore the possible mechanism of curcumin in inducing the apoptosis of breast cancer cell MDA-MB-231.

METHODCurcumin of different concentrations at 0, 10 25, 50, 100, 150, 200 micromol x L(-1) were used to intervene breast cancer cells MDA-MB-231 for 24 hours. MTT was used to observe its effect on the proliferation of breast cancer cells. The flow cytometry was used to detect its effect on the cell apoptosis. The real-time quantitative PCR and Western blot was used to assess the expression levels of GRP78 and CHOP in breast cancer cells.

RESULTCurcumin could inhibit the proliferative ability of breast cancer cells by inducing them in a concentration-dependent manner. Curcumin could significantly increase the expression levels of GRP78 and CHOP in breast cancer cells.

CONCLUSIONCurcumin could induce the apoptosis of breast cancer cells MDA-MB-231 by activating endoplasmic reticulum stress.

BACKGROUND:Open reduction is general y not advocated for the treatment of children clavicle fracture, because the thick and tough periosteum remains intact and attached by the ligament attachment. In clinic, twin-ring external fixation and simple suspension are commonly used, but there is no reliable basis on which method can get better effect.
OBJECTIVE:To compare the stability of twin-ring external fixation and simple suspension for the treatment of children clavicle fracture.
METHODS:The patients with children clavicle fracture and treated by twin-ring external fixation and simple suspension were selected from June 2008 to December 2012, including 17 patients treated with simple suspension and 22 patients treated with twin-ring external fixation. The X-ray film examination was performed regularly to observe the fracture healing and shoulder function.
RESULTS AND CONCLUSION:The 17 patients treated with simple suspension had good healing;three cases had gap between fracture ends at 1 week after treatment, and re-suspension to increase the height and final y two fracture ends contacted in one case;for the other two cases, there was stil gap between fracture ends, and changed for twin-ring external fixation, the fracture ends contacted. Al the 22 patients in the twin-ring external fixation group obtained healing;five cases had performance of upper extremity neurovascular compression on the fracture side after fixation;after releasing, three cases had recovery, and two cases were treated with simple suspension, the fracture ends began to contact;six cases had armpit redness;four cases had early sleep difficulties;two cases had gap between fracture ends at 1 week after treatment, and after re-adjust, the fracture ends contacted in two cases. The results showed both two methods could not cause appearance deformity, and both could get healing. The simple suspension fixation is easy to operate with reliable effect, and it is comfortable which make it easy to accept by the children, it has the advantages of early for functional exercise, less tissue damage, does not affect the blood supply;the twin-ring external fixation is easy to compress the axil ary arteries and nerves on both sides, thus resulting in upper extremity swel ing, numbness and skin redness, and it can cause discomfort night sleeping and poor comfort which is not easy for children to accept. But, no matter what method we take, the review after 1 week, as wel as the line between proximal and distal part and the contact between fracture ends is stil important.

[Objective]To determine the efficacy of early versus late reconstruction for anterior cruciate ligament rupture.[Method]The author searched MEDLINE(1950-2007.4),OVID(1950-2007.6),PUBMED(1950-2007.7),the CBM(1978-2007.6),WanFang(1981-2007.6),and hand-searched several related journals for randomized controlled trials(RCTs)and quasi-randomized controlled trials(quasi-RCTs)involving the efficacy of early versus late reconstruction for anterior cruciate ligament rupture,the quality of the included trials was assessed.RevMan 4.2.8 software was used for statistical analysis.[Result]Ten studies were included(1RCT,9 CCT).The results of meta-analysis indicated that the huge heterogeneity consist in as follows:intraarticular meniscus tears of the knee,extension deficit of the knee,comparison of lysholm of the knee after the operation.No statistically significant differences between the two operative procedures were observed as follows:including the result of incidence of intraarticular chondral damage of the knee,comparison of Lachman test of the knee found after the operation as well as the result of incidence of comparison of Pivot test of the knee found after the operation.Statistically significant differences were more observed in the late reconstruction in the clinical outcome of both intraarticular arthofibrosis and flexion deficit of the knee found after the operation than that of early reconstruction.[Conclusion]Although result obtained on the basis of CCT with a lager bias and one RCT,the author still conclude that statistically significant differences are more observed in the late reconstruction in the clinical outcome of both intraarticular arthofibrosis and flexion deficit of the knee found after the operation than that of early reconstruction.More high quality,large-scale randomized controlled trials are required for the accurate conclusion in treating it.

In order to explore the possibility of Xihuangwan (XHW)'s application in assistant therapy in patients with breast cancer, short- and long-term clinical efficacy were assessed in this study. Eighty and four patients with advanced breast cancer were selected in this study. They were divided into control group and treatment group randomly and evenly. All patients received surgical treatment followed by chemotherapy regimen composed of PTX + EPI + CTX (TEC regimen). Treatment group received additional assistant treatment of XHW. Short-term clinical efficacy was assessed by KPS, lesion stabilizing rate and side effects in 3-month follow-up study. Long-term clinical efficacy was assessed by overall survival (OS) and free-progression survival (FPS). KPS increased significantly after treatment in all patients (P < 0.05), more significantly in treatment group than in control group after treatment (P < 0.05); lesion stabilizing rate in treatment group increased significantly in treatment group than in control group (92.86% vs. 85.71%, P < 0.05); there was no significant difference between control group and treatment group in occurrence of side effects. Compared with control group, OS and FPS increased significantly in treatment group. Data in this study showed that XHW was suitable in treatment of advanced breast cancer due to its satisfactory short-term and long-term therapeutic effects.

Objective] To explore a new method of synthesis of resveratrol oligmer induced by photosensitizers, further analyze its free radical scavenging activity and analgesic activity. [Method] Resveratrol was dispersed in pH 7.4 phosphate buffer solution, mixed with pheophorbide, then illuminated by laser at 630nm. The oligmers in the filtrate were analyzed by HPLC-MS and isolated by preparative liquid chromatography. Free radical scavenging activity was determined by DPPH and ABTS method, and the analgesic effect was measured by hot plate test and acetic acid writhing test in mice. [Result] A new peak occurred and reached stable in reactive solution after 20 min illumination. It was identified as the dimer of resveratrol with conversion of 35%. Its concentrations on inhibition of 50% DPPH and ABTS radical were respectively 230 μg·mL-1 and 273 μg·mL-1. It reached maximum pain threshold at 180 min, and the inhibition rate of writhing number was 62.6% with better effects than resveratrol. [Conclusion] Reseratrol can be polymerized to the dimer after pheophorbide excited by red light, the resveratrol and its dimer both have the ability of eliminating free radicals and analgesic effects, but the dimer has the stronger activity.
