Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.

PURPOSE: Angiopoietin-1 (Ang1) is a critical factor for vascular stabilization and endothelial survival via inhibition of endothelial permeability and leukocyte- endothelium interactions. Hence, we hypothesized that treatment with umbilical cord mesenchymal stem cells (UCMSCs) carrying the Ang1 gene (UCMSCs-Ang1) might be a potential approach for acute lung injury (ALI) induced by lipopolysaccharide (LPS). MATERIALS AND METHODS: UCMSCs with or without transfection with the human Ang1 gene were delivered intravenously into rats one hour after intra-abdominal instillation of LPS to induce ALI. After the rats were sacrificed at 6 hours, 24 hours, 48 hours, 8 days, and 15 days post-injection of LPS, the serum, the lung tissues, and bronchoalveolar lavage fluid (BALF) were harvested for analysis, respectively. RESULTS: Administration of fluorescence microscope confirmed the increased presence of UCMSCs in the injured lungs. The evaluation of UCMSCs and UCMSCs-Ang1 actions revealed that Ang1 overexpression further decreased the levels of the pro-inflammatory cytokines TNF-α, TGF-β1, and IL-6 and increased the expression of the anti-inflammatory cytokine IL-10 in the injured lungs. This synergy caused a substantial decrease in lung airspace inflammation and vascular leakage, characterized by significant reductions in wet/dry ratio, differential neutrophil counts, myeloperoxidase activity, and BALF. The rats treated by UCMSCs-Ang1 showed improved survival and lower ALI scores. CONCLUSION: UCMSCs-Ang1 could improve both systemic inflammation and alveolar permeability in ALI. UC-derived MSCs-based Ang1 gene therapy may be developed as a potential novel strategy for the treatment of ALI.

OBJECTIVETo investigate the effects of citrus reticulata blanco extract on the proliferation and collagen metabolism of fibroblasts from human hypertrophic scar.

METHODSHuman hypertrophic scar fibroblasts from two burn patients obtained from plastic surgery were cultured in vitro and divided into experimental group (n = 12, with basic culture medium and 2.5, 5.0, 10.0,25.0 mg/L citrus reticulata blanco extract, respectively, 3 bottles for each concentration of citrus reticulata blanco extract ), control group 1 (n = 3, with basic culture medium) , and control group 2 ( n = 3, with basic culture medium and 5% ethyl alcohol). The cell proliferation in each group was observed with MTT method, then the inhibition rate was calculated. Apoptosis and its index ( AI) in each group were determined after TUNEL staining . The changes in the content of ICTP and PINP in each group were observed by radioimmunity.

RESULTSThe inhibition rate in the experimental group with the citrus reticulata blanco extract in concentration of 2. 5, 5.0, 10.0, 25. 0 microg/ ml were (7. 100+/-0.038)% , (8. 100+/- 0. 048)% , (10. 900+/-0. 055)%, (15.900+/-0. 097) %, respectively, which were significantly higher than those in other two groups ( P <0.05 ). The Al (69. 7% , 71.7%, 86.4% , 95.2% ), ICTP [(17.2+/-0.6), (18.3+/-0.6), (19.8+/-0.5), (23.2+/-0.6) microg/L] and PINP [ (101.7+/-1.4) , (107. 8+/-1. 1) , (111.6+/-1.2) , (124. 6+/-1.3) microg/L] in experimental group with the citrus reticulata blanco extract in concentration of 2.5, 5.0, 10.0 , 25.0 mg/L were also obviously higher than other two control groups( P <0.05) ,but these indices in control 1 group were similar to those in control 2 group( P >0. 05).

CONCLUSIONThe citrus reticulata blanco extract might be beneficial for the management of hypertrophic scar through inhibition of the proliferation of fibroblasts in hypertrophic scar, by promoting apoptosis and collagen degradation.

OBJECTIVETo investigate the distribution of epidermal stem cells (ESCs) in different degrees of burn wounds in scalded rats.

METHODSThirty-two Sprague-Dawley (SD) rats were employed in the study. First degree (I), shallow (shallow II) and deep partial thickness (deep II) and full thickness burn wounds (III) were created on the rat skin. Burn wound samples were harvested at 24 postburn hours (PBHs) from all the wounds and were processed to tissue slices. The tissue slices were stained by immunohistochemistry technique. The expression and distribution of ESCs in different degrees of burn wounds were observed with integrins alpha 2 beta 1 and keratin 10 (K10) as first antibodies.

RESULTSK10 positive cells were found to distribute in the strata spinosum, granulosum and lucidum in the first degree burn wound (I) with large amounts of integrins alpha 2 beta 1 positive cells in the residual basal layer and skin appendages (hair follicles) in shallow partial thickness burn wound (shallow II degree), and there were less integrins alpha 2 beta 1 positive cells in the remaining skin appendages in deep dermis in deep partial thickness burn wound (deep II degree). Finally, integrins alpha 2 beta 1 positive cells were sparsely found in the III degree burn wound.

CONCLUSIONThe distribution of ESCs in burn wounds was closely related to the depth of burn wound. The residual ESCs might be the origin of burn wound regeneration and reepithelization.

OBJECTIVETo investigate the mechanism and the accelerating effect of rhEGF and rhbFGF on wound healing.

METHODSTwelve New Zealand rabbits with 72 incised wounds on ventral side of 24 ears were randomly divided into two therapeutic groups (rhEGF of 10 ug/cm(2) and rhbFGF of 100 AU/cm(2)) and a control group (1% silver sulfadiazine cream, SD-Ag). The general conditions of the wound healing was observed grossly. Biopsies were harvested at different time points for the pathomorphological examination, the electron microscopic examination, and for assessment of integrin beta1 mRNA expression by in situ hybridization.

RESULTSThe expressions of integrin beta 1 mRNA in two therapeutic groups were significantly higher than that of control group. The quality of the wound healing was improved in therapeutic group with its healing time shortened when compared with that in control group (P < 0.05). There was an obvious difference in the number of fibroblasts and capillary gemmules between the therapeutic and control groups (P < 0.05).

CONCLUSIONThe wound healing and quality could be improved by both rhEGF and rhbFGF, but rhbFGF seemed better to be employed during the early and middle stages of the wound repair for the growth of granulation tissue, while rhEGF should be applied at the late stage of wound repair to accelerate the re-epithelialization of the wound. Combined application of rhEGF with rhbFGF according to time effect could be more beneficial to the wound repair.

OBJECTIVETo study the effects of benzo(a)pyrene (BaP) on the cell cycle distribution and activities of mitogen-activated protein kinase (MAPK) signal molecules (ERK1/2, JNK1/2 and p38) in human embryo lung cells (HELF), and to investigate the relationship between alterations of MAPK protein phosphorylation and the cell cycle distributions.

METHODSThe phosphorylation of MAPK were induced by exposing HELF cells to BaP at 0.1, 0.5, 2.5 and 12.5 micromol/L. The phosphorylation and protein expression levels of ERK1/2, JNK1/2 and p38 were determined through western-blotting assay. And the flow cytometry assay was used to measure the cell cycle effects in HELF cells after treatment with 2.5 micromol/L BaP for 24 h.

RESULTSThe phosphorylation levels of ERK1/2, JNK1/2 and p38 were significantly increased through BaP exposure. In addition, the phosphorylation of these three MAPKs has similar alteration pattern. We found that exposure of cells to 2.5 microM of BaP for 24 h resulted in a decrease of G(0) and G(1) population by 11.9% (F = 41.38, P < 0.01) and an increase of S population by 17.2% (F = 68.13, P < 0.01). Three chemical inhibitors of MAPK (AG126, SP600125 and SB203580) could significantly inhibit the cell cycle alteration because of BaP treatment.

CONCLUSIONERK1/2, JNK1/2 and p38 could positively regulate the BaP independently induced cell cycle alterations.

BACKGROUNDThe radiochemotherapy regimen concomitantly employing temozolomide (TMZ) chemotherapy and radiotherapy (RT) 4 weeks after surgery, followed by 6 cycles of TMZ is a common treatment for glioblastoma (GBM). However, its median overall survival (OS) is only 14.6 months. This study was to explore the effectiveness and safety of early TMZ chemotherapy between surgery and chemoradiotherapy plus the standard concomitant radiochemotherapy regimen.

METHODSA randomized, parallel group, open-label study of 99 newly diagnosed GBM patients was conducted at 10 independent Chinese neurosurgical departments from June 2008 to June 2012. Patients were treated with concomitant radiochemotherapy regimen plus early postsurgical temozolomide (early TMZ group) or standard concomitant radiochemotherapy regimen (control group). Overall response was assessed based on objective tumor assessments, administration of corticosteroid and neurological status test. Hematological, biochemical, laboratory, adverse event (AE), and neurological condition were measured for 24 months of follow-up. The primary efficacy endpoint of this study was overall survival (OS). The secondary endpoint was progression free survival (PFS).

RESULTSThe median OS time in the early TMZ group was 17.6 months, compared with 13.2 months in the control group (log-rank test P = 0.021). In addition, the OS rate in the early TMZ group was higher at 6, 12, and 18 months than in the control group, respectively (P < 0.05). The median PFS time was 8.7 months in the early TMZ group and 10.4 months in the control group (log-rank test P = 0.695). AEs occurred in 29 (55.8%) and 31(73.8%) patients respectively in early and control groups, including nausea (15.4% vs. 33.3%), vomiting (7.7% vs. 28.6%), fever (7.7% vs. 11.9%), and headache (3.8% vs. 23.8%). Only 30.8% and 33.3% were drug-related, respectively.

CONCLUSIONSAddition of TMZ chemotherapy in the early break of the standard concomitant radiochemotherapy regimen was well tolerated and significantly improved the OS of the GBM patients, compared with standard concomitant radiochemotherapy regimen. However, a larger randomized trial is warranted to verify these results.

OBJECTIVE: To evaluate the clinical efficacy of warm moxibustion therapy in the recovery of quadriceps muscle strength in patients undergoing total knee arthroplasty (TKA) with analgesia of the femoral nerve block (FNB). METHODS: A total of 174 patients with KOA were randomized into a warm moxibustion group and a rehabilitation group, 87 cases in each group. In the warm moxibustion group, warm moxibustion combined with conventional quadriceps strength training were used. In the rehabilitation group, conventional quadriceps strength training was given. The warm moxibustion was applied at Liangqiu (ST 34) and Zusanli (ST 36), the treatment was given twice a day, 7 days for one course, with a total of 2 courses.The quadriceps muscle strength of the two groups was recorded and compared at 24 h before FNB, 24, 48, 72 and 96 h after surgery, and the resting and exercise VAS pain scores were also recorded at the same time point. And the first time for standing up and the first straight raising time in the two groups were compared, and the occurrence of adverse reactions in the two groups were observed. RESULTS: At 24, 48, 72 and 96 h after FNB, the quadriceps muscle strength in the warm moxibustion group was better than that in the rehabilitation group (<0.05, <0.01). At 72 h and 96 h after FNB, the resting and exercise VAS scores of the warm moxibustion group were lower than those of the rehabilitation group (both <0.001). The average first straight leg raising time in the warm moxibustion group was postoperative (31.03±10.78) h, and the time in the rehabilitation group was postoperative (47.23±15.78) h. The difference was statistically significant (<0.001). The average time of the first time for standing up in the warm moxibustion group was postoperative (25.76±7.00) h, and postoperative (33.12±11.18) h in the rehabilitation group. The difference was also statistically significant (<0.001). No adverse reactions occurred in both groups. CONCLUSION Warm moxibustion combined with conventional quadriceps strength training can improve the symptoms of quadriceps weakness in patients with femoral nerve block after total knee arthroplasty, and accelerate the recovery of joint function, which is superior to conventional quadriceps strength training.
