Objective Under the requirements of dose distribution in target and normal tissue ,five radiotherapy fields are de‐voted to making Intensity‐modulated radiation therapy (IMRT) plan ,thus the IMRT radiotherapy of Nasopharyngeal Carcinoma (NPC) could be underway with the radiotherapy field as few as possible .Methods Through the comparison of the NPC patients′IMRT plans in our hospital ,the angle of fields have been make out with 0° ,75° ,125° ,225°and 285° .At the same time ,this field scheme is compared with projects of front five fields ,behind five fields and share five fields .The result was statistically analyzed . Results In these four field schemes ,the maximum and minimum dose in the target area showed no statistically difference (P>0 . 05) ,while in the average dose ,D95 and normal tissue dose have statistical difference (P<0 .05) .Conclusion Comprehensive com‐parison of the dose distribution in the target and normal tissue in these four field schemes showed that the field scheme with the an‐gles of 0° ,75° ,125° ,225°and 285°could obtain better results ,so this field scheme should be more suitable for local area NPC patient′s IM RT .

ATP sensitive potassium channels (K ATP ) have been thought to be a mediator of cardioprotection. Recent pharmacologic and molecular biology studies show the protective effects of K ATP openers are not dependent of action potential shortening and cardiodepressant effects, but mediated by preservation of mitochondrial function, which suggests a role for intracellular mitochondrial K ATP (mito K ATP ). The mechanism by opening mito K ATP produces cardioprotection is less clearer, however, it is thought that a beneficial effect may occur as the result of K + entry and intramitochondrial depolarization. This effect would reduce mitochondrial calcium overload and cause matrix swelling, which are shown to enhance ATP synthesis and stimulate mitochondrial respiration.

To explore the effect of lycorine in inducing apoptosis of pulmonary carcinoma cell A549 and its mechanism. In the study, pulmonary carcinoma cell A549 were taken as the experimental subject and processed with different concentrations of lycorine (0, 0.5, 1.0, 2.0, 4.0 and 8.0 μmol x L(-1)). The MTT method was used to observe the cell proliferation. The apoptosis rate of A549 cells was determined by Annexin FITC/PI double staining. The microplate reader was used to detect the activities of Bcl-2, Bax and p53. The changes in mitochondrial membrane potential were measured by the flow cytometry. The expressions of apoptosis-related factors Bcl-2, Bax, p53 and Survivin were determined by Real-time PCR. The results showed that lycorine significantly inhibited the proliferation of A549 cells (P < 0.05), induced the apoptosis on A549 cells (P < 0.05), increased the activities of Bax and p53, reduced Bcl-2 activity and mitochondrial membrane potential, and notably changed the gene expressions of Bcl-2, Bax, p53 and Survivin (P < 0.05). In conclusion, lycorine can induce the apoptosis of A549 cells and be applied to treat pulmonary carcinoma. Its mechanism may be related to the activation of relevant factors in Bcl-2 signaling pathway.

Objective:To explore the result of application of the clinical nursing pathway on percutaneous coronary interventional patient.Methods:One hundred patients were divided into two groups randomly,each group has 50 cases.We used the clinical nursing pathway based on holistic nursing case in experimental group,and the control group used the holistic nursing care.Results:After use the method of the clinical nursing pathway in the hospital,the medical cost and the rates of the nursing errors were less than that in the comparing group while the patients were more satisfied.Conclusion:As a scientific mode,the clinical nursing pathway could improve the working efficiency,guarantee the nursing quality.

Chronic atrophic gastritis (CAG), a chronic disease of the digestive system resulting from multi-pathogenic factors, is precancerous state of gastric cancer. Authors reviewed the current situation of Chinese medical diagnosis and treatment of CAG, and looked forward to its prospect by combining with their own clinical experience and scientific researches.

The "Cancer Toxin" pathogenesis theory is an innovate theoretical system for cancer pathogenesis of Chinese Medicine, which was built on the basis of "Cancer Toxin" concept initially raised by Professor ZHOU Zhong-ying. The mechanism of the transformation from inflammation to carcinoma has become one of hot-points in the field of cancer research at home and abroad in recent years. We focused on discussing the relevance of the "Cancer Toxin" pathogenesis theory with the transformation mechanism from inflammation to cancer, provided evidence for using "Cancer Toxin" pathogenesis theory in intervening transformation from inflammation to cancer, hoping to guide for Chinese medical prevention and treatment of tumor.
