Postoperative radiotherapy for completely resected stage Ⅲ A-N2 non-small cell lung cancer / 国际肿瘤学杂志

Current studies show that postoperative adjuvant radiotherapy (PORT)may improve local control and overall survival for Ⅲ A-N2 NSCLC.With modern radiotherapy technology and techniques,the adverse effect of PORT is moderate and tolerated.Besides,modern PORT doesn′t decrease the survival.Inves-tigation concerning postoperative target volume for PORT is rare,so that definite agreement has not been reached.Available informations suggest that clinical target volume should include bronchial stump,involved lymph nodes,ipsilateral hilar nodes,subcarinal nodes and ipsilateral lower paratracheal nodes.

The research progress of amniotic fluid-derived mesenchymal stem cells in cancer therapy / 实用肿瘤学杂志

Amniotic fluid-derived mesenchymal stem cells(AF-MSCs)are multipotential,nonhemato-poietic progenitor cells that have an inherent ability to self -renew and to differentiate into many cell types ,inclu-ding osteoblasts,chondrocytes and adipocytes.Despite their high proliferation rate,no in vivo tumorigenicity has been reported and their karyotype was normal even after extensive expansion in culture .Several studies have dem-onstrated the inherent tumortropic properties of MSCs and their successful use as cellular vehicles of therapeutic agents for the treatment of several types of cancer .This article reviews recent articles on studying the role of amni-otic fluid-derived mesenchymal stem cells in cancer therapy .

Pregnane X Receptor(PXR) and Constitutive Androstane Receptor(CAR) in the Multidrug Resistance / 实用肿瘤学杂志

Chemotherapy is one of the three most common treatment modalities for cancer .However , chemotherapy as current firstline therapy induces significant side effects and limited efficacy ,leading to multidrug resistance and fast recurrence challenging the patient survival rate .Drug metabolizing enzymes ( DMEs) and efflux transporters promote the metabolism,clearance,and detoxification of chemotherapeutic agents .Nuclear receptors, especially pregnane X receptor (PXR,NR112)and constitutive androstane activated receptor (CAR,NR113),reg-ulate the expressions of target genes that could encode phase I DMEs ,phase II DMEs,and efflux transporters in the development of multidrug resistance ( MDR) during chemotherapy .Recent studies have revealed that PXR and CAR play pivotal roles in MDR of various human carcinomas .And their expressve levels or activation statuses could predict the risk of drug resistance in the patients subjected to chemotherapy .Accordingly ,PXR/CAR antag-onists,combining with existing chemotherapeutics that activate PXR /CAR,are promising options that could over-come MDR in cancer.

Effects of long term use of beclomethasone dipropionate nasal spray on bone density with perennial allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the effects of long term use of beclomethasone dipropionate (BDP) nasal spray on bone density with perennial allergic rhinitis (AR) in adults.@*METHOD@#A 5-year randomized study was conducted on the effects of BDP nasal spray on serum calcium, phosphorus, alkaline phosphatase, and bone density determined before and after the treatment in 36 adult patients with perennial AR. 20-45 years of age, were randomly divided into 3 groups. That is group A (nasal spray 1 - or =5 year). The data were analyzed by paired t test.@*RESULT@#The perennial AR were followed up for more than > or =1 year, > or =3 year and > or =5 year to observe the influences of nasal spray BDP. There were no significant difference between the data examined before and after the treatment (P > 0.05). Bone development is not influenced by nasal spray BDP < or =400 microg/d within 5 years.@*CONCLUSION@#Long term use of BDP nasal spray in adult patients does not lead to osteoporosis if the lowest effective steroid dose is given.

Observation of short-term curative effect of Suxiao Jiuxin Pill on coronary heart disease and angina pectoris / 中成药

AIM: To observe the short-term curative effect of Suxiao Jiuxin Pill on coronary heart disease (CHD) and angina pectoris. METHODS: 187 patients were divided into two groups at random:the treatment group with 105 cases and the control group with 82 cases. The treatment group was given Suxiao Jiuxin Pill 6 pills tid and the control group was given Compound Danshen Dripping Pill 6 pills tid orally. The treating period was 2 weeks. Before and after treatment angina pectoris was observed and electrocardiogram was determined. RESULTS: Suxiao Jiuxin Pill could significantly alleviate syndrome of CHD in patients, lessen electrocardiogram and decrease dosage of nitroglycerin. The total effective rate on angina pectoris and the effective rate in improving electrocardiogram was higher in treatment group than that in control group (P
