AIM:To investigate the change in expression of p53 ,Bcl-2 ,and Bax genes in human colon cancer cells transplanted into nude mice after hyperthermia,chemotherapy,radiotherapy,thermochemotherapy,thermoradiotherapy and thermochemoradiotherapy. METHODS:Human colon cancer cell line (HT29) was transplanted into the hind limbs of nude mice. Under laboratory simulated conditions of hyperthermia (43℃,60 min),the actual radiation doses and doses of mitomycin C (MMC) were calculated in reference to the clinical radiotherapy for human rectal cancer and chemotherapy prescription for colon cancer. The mice were divided into 6 groups according to the treatment approaches:hyperthermia,chemotherapy,radiotherapy,thermochemotherapy,thermoradiotherapy,and thermochemoradiotherapy. The mice were sacrificed at different time points and the tumor tissue was taken for further procedures. The morphologic changes in membrane,cytoplasm and nuclei of tumor cells of p53,Bcl-2,and Bax after treatment,were observed by immunohistochemistry staining. RESULTS:All of the six treatment modalities down-regulated the expression of p53,Bcl-2 and up-regulated the expression of Bax at different levels. The combined therapy of hyperthermia,with chemotherapy,and/or irradiation showed a greater effect on down-regulating the expression of p53 (0.208 ± 0.009 vs 0.155 ± 0.0115,P < 0.01) and Bcl-2 (0.086 ± 0.010 vs 0.026 ± 0.0170,P < 0.01) and up-regulating Bax expression (0.091 ± 0.0013 vs 0.207 ± 0.027,P < 0.01) compared with any single ***:Hyperthermia enhances the effect of radio-and chemotherapy on tumors by changing the expression of apoptosis genes,such as p53,Bcl-2 and Bax.

Induced radioactivity is one of the essential problems in the radiation protection field of proton accelerators. Research on the induced radioactivity of low-energy proton accelerators is highly limited. Given such context, this study investigates the cross section of 63Cu (p, n) 63Zn and 65Cu (p, n) 65Zn in Cu targets at 11 MeV proton accelerators through an activation experiment. The uncertainties of the results are analyzed in detail. Results show that the cross section of the reaction of 65Cu (p, n) 65Zn in the experiment is only 1.36% lower than that of the FLUKA simulation, whereas the reaction of 63Cu (p, n) 63Zn in the experiment is 25.4% higher than that of the FLUKA simulation. Given that the benchmark for the FLUKA code of low-energy proton accelerators is very limited, this study provides a reference in this field. © 2014, Science Press. All rights reserved.

Objective To explore the effects of dermabrasion combined with ReCell on large superficial facial scars caused by burn, trauma and acnes. Methods Nineteen patients with large superficial facial scars were treated by the same surgeon with dermabrasion combined with ReCell？. According to the etiology, patients were classified into post-burning group （n=5）, post-traumatic group （n=7） and post-acne group （n=7）. Fifteen patients completed the follow-ups, 5 patients in each group. Healing time, complication rate, the preoperative and 18-month-post-operative assessments using Patient Satisfaction Score （PSS）, Vancouver Scar Scale （VSS）, and Patient and Observer Scar Assessment Scale （POSAS） of each group were analyzed to compare the effect of the combined therapy on *** The healing time of post-burning group （19.6±4.0 days）, post-traumatic group （15.8±2.6 days）, and post-acne group （11.4±3.1 days） varied remarkably （F=7.701, P=0.007）. The complication rates were 60%, 20%, and 0 respectively. The post-operative POSAS improved significantly in all groups （P〈0.05）, where the most significant improvement was shown in the post-acne group （P〈0.05）. The post-operative PSS and VSS improved only in the post-traumatic group and post-acne group （all P〈0.05）, where the more significant improvement was also shown in the post-acne group （P〈0.05）. Conclusions The combined treatment of dermabrasion and ReCell has remarkable effect on acne scars, moderate effect on traumatic scars and is not suggested for burn scars. POSAS should be applied to assess the therapeutic effects of treatments for large irregular scars.

A series of PdNi/Al2O3 catalysts with different compositions was prepared by co-reduction method. The influence of Ni amount on the catalytic combustion of methane was studied. X-ray diffractometry and X-ray photo- electron spectroscopy were employed to characterize the dispersion and electronic state of the active phase. Tempe- rature-programmed oxidation was carried out to study the thermal stability affected by Ni doping. It has been demon- strated that Ni addition changed particle size and oxidation state of PdOx. The results indicate that the promotion of Ni to the Pd/Al2O3 resulted from both size effect and electronic effect. In addition, the thermal stability of the Ni-doped catalysts were enhanced.

The influence of the wettability of a catalyst on the performance of the liquid phase oxidation of p-cresol was investigated. It was found that the surface hydrophobicity of a catalyst, which can be changed by modification with various loadings of polyvinylidene fluoride（PVDF）, has a promotion effect on the catalytic performance. At the same time, the reaction parameters such as oxygen pressure, molar ratio of NaOH to p-cresol, reaction temperature and time on the catalytic performance in the liquid-phase oxidation of p-cresol were optimized. As a result, 10%（mass fraction） PVDF modified cobalt pyrophosphate gave the highest conversion of 94.2% of p-cresol with a selectivity of 94.4% for p-hydroxybenzaldehyde at 348 K and a molar ratio of4：l of NaOH/p-cresol and an oxygen pressure of 1.0 MPa for 3 h.
