Objective To investigate the effect of UCP2 on cell proliferation, apoptosis, metastasis in cervical squamous carcinoma. Methods Plasmid?mediated downregulation of UCP2 was obtained in cervical cancer cell lines. MTT, flow cytometry and transwell chamber assay were conducted to detect the ability of proliferation, apoptosis and metastasis. Characteristics of UCP2 protein was analyzed by bioinformatics methods. Results (1)UCP2 was verified to be downregulated by qRT?PCR and Western blotting assay.(2)MTT, apoptosis assay and transwell chamber assay showed that the proliferation of SiHa cell was significantly inhibited, and the apoptosis rate was significantly increased, and metastasis was markedly deduced (P < 0.05). (3) Bioinformatic analysis showed that UCP2 was located in mitochondria with several phosphorylation sites, and UCP2 interacted with other proteins to produce biological effects. Conclusion UCP2 may play an important role in the occurrence and development of cervical cancer, and it is expected to be a new target for the early diagnosis and treatment of cervical cancer.

AIM: To study the effects and mechanisms of norepinephrine (NE) on the activity of nuclear factor-kappa B (NF-?B) in cardiomyocytes. METHODS: Using the cultured neonatal rat cardiac myocytes, the levels of reactive oxygen species and the nuclear DNA binding activity of NF-?B were measured in cardiomyocytes before and after stimulated with NE alone, NE+prazosin+propranolol, and NE+vitamin E, respectively. RESULTS: NE increased significantly the levels of reactive oxygen species and NF-?B activity in cardiac myocytes. These effects of NE were attenuated by vitamin E pretreatment, as well as prazosin and propranoloe. CONCLUSION: The effects of NE on cardiomyocytes might be exerted partly through NF-?B activation, and associated with NE-induced overproducion of reactive oxygen species via the adrenergic receptor pathway.

Objective To explore the application value of mammary gland remodeling to one-stage repair local defects after partial excision.Methods The clinical data of 62 breast patients undergoing mammary gland remodeling to one-stage repair local defect after partial excision between January 2011 and December 2014 were reviewed.Results All patients recovery,the average operative time was 60 min,the average hospital stay was 7 days,the average cost was 5 216 yuan,1 case with postoperative concurrent incision infection,6 cases with postoperative hematoma.The cosmetic results were excellent or good rate was 87.1% (54/62),and fair rate was 12.9% (8/62).The breasts showed natural and symmetrical appearance during a follow-up of 12-36 months.Conclusions The application of mammary gland remodeling to one-stage repair local defect after partial excision is a safe and economical method.

Objective The research is to study the temperature rising situation in the thermochemotherapy process of the domestic dog through the hepatic artery, and the bearing ability of heart, liver, and kidney during the process, as well as the biochemical and histological change of the liver after the procedure. Methods A thermostated container of water bath and an infusion pump, both designed domestically, were adopted. Ten domestic dogs were divided into 2 groups of A and B with 5 dogs respectively. Through hepatic artery infusion for group A, glucose solution (GS) was administered at 43?C for 30 minutes, with the flowing rate of 30ml/min, in group B 5% GS at 45?C for 30 minutes, with the flowing rate of 40ml/min added with chemotherapy drug MMC(0.2mg/kg) was administered to 3 dogs and 5% GS with the same flowing rate added with CDDP(1mg/kg) into other 2 dogs. Results The temperature of anus and liver was 0.3~0.5?C and 0.5~1.0?C higher than before the procedure respectively, there was no significant rate changes of heart and respiration during and before the procedure. Four dogs were radiographied after 15 minutes' infusion, showing different degrees of hepatic artery dilation accompanied with relevant increase of infusion. Six dogs were radiographied after 30 minutes' infusion, 5 of them showed arterial contraction astescal on accompanied with relevant decrease of infusion. There appeared slight or moderate increase of aminopherase after the procedure, but in actually returned to normal within a week. Pathologically, there appeared no acute effect on heart, lung and kidney other than slight and reversible damage to hepatic tissue. Conclusions Healthy dogs can endure the chemotherapy treatment of infusion through hepatic arterial fistula at 43?C 45?C for 30 minutes.

Objective To summarize the current value of neoadjuvant chemotherapy(NAC) for potentially resectable gastric cancer.Methods The recent 5-year literatures searched through the PubMed with the key words:stomach neoplasm,gastric cancer/carcinoma,neoadjuvant therapy/chemotherapy and preoperative therapy/chemotherapy as well as the relevant reports presented in the ASCO Annual Meeting in 2007 and 2008 were analyzed.The present status of NAC for advanced gastric cancer was summarized,the necessity and feasibility were evaluated,and the patients features for selecting,the predictors for response,the mainly existing problems and development trend of NAC were analyzed.Results At present,there were 7 randomized control trails(RCT) published,and among them 3 were phase Ⅲ.It was safe,effective and feasible to most of trails in NAC for gastric cancer.However,it was still little to obtain survival benefit for NAC RCT,and short of randomized trial comparing strict preoperative chemotherapy to surgery alone or perioperative chemotherapy to surgery plus adjuvant chemotherapy.It remained lots of problems such as how to select the appropriate patients,the effective induced regimes and the predicted factors,the evaluated indices for response.Conclusion NAC is a safe,feasible and efficient method to potentially resectable gastric cancer,but strict phase Ⅲ randomized trials are needed.In the future,substantial improvements of treatment outcome will likely depend on the novel drugs and molecular biological targeted therapies.
