The theory of ascending and descending activities of qi is one basic theory that guides diagnosis and treatment of disease clinically. It has been esteemed by ancient physicians throughout their academic thinking and clinical diagnosis. As a kind of unbalanced disease in the whole body, the basic internal mechanism of tumor formation may be caused by unbalanced ascending and descending activities of qi. Better clinical efficacy is liable to get by applying the theory of ascending and descending activities of qi in cancer treatment. Therefore, we hope to provide a reference for clinicians from the following aspects: historical status and academic value of the theory of ascending and descending activities of qi, case examples and classical prescriptions.

As a characteristic tumor therapy in China, Chinese medicine (CM) plays an important position in comprehensive treatment of tumor. It's a critical issue of objective realization, analysis and evaluation of CM safety for scientific decision-making in tumor safe medication and it also is a pivotal issue which affects the international communication. The safety evaluation of CM includes three phases: pre-clinical safety evaluation, clinical trials (micro-dose studies and traditional clinical trials) and post-marketing CM safety assessment. The key point of evaluation should be distinguished among different stages and various types of CM (such as classic formulas, Chinese herbal extracts, etc). Emphasis should be given to chronic toxicity when evaluating oral Chinese herbal , microdose studies and quality control must be underlined while injection is evaluated and more attention should be pay to the dose-effect relationship and time-effect relationship when turned to toxic Chinese medicine , and so as for the toxicity grading study. Moreover, we should constantly improve CM safety assessment method in various stages of tumor treatment, such as introducing the concept of syndrome classification theory, bringing in metabonomics and real-world research method which are similar to the CM therapeutic concept. Most importantly, we must keep its own feature of CM theory when we learn the concept of safety evaluation from abroad. Actively exploring the anti-tumor medicine safety evaluation methods and strategies is of great significance for clinical and experimental research, and it can provide supportability platform to CM's international communication.

Objective To reveal the effects of circadian gene Per2 on growth of human lung cancer cell A549 cell and its mechanism. Methods pcDNA3.1(+)-Per2 was transfected into A549 cells and controlled with the vector pcDNA3.1(+). The expression of Per2 was confirmed with RT-PCR and western blot. The Inhibitory effect of Per2 on cell growth and proliferation was demonstrated with MTT assay and colony-forming assay. Apoptosis was detected with flow cytometry. Results The circadian gene Per2 exhibited a growth-inhibitory and apoptosis-inductory effect on A549 cells. Conclusion The results indicate that Per2 may inhibit A549 cell proliferation,which mechanism might involve cellular apoptosis.

Objective To review the experience of OPCAB and plication of left ventricular aneurysm. Methods Without cardiopulmonary bypass, heparin was given at 1.0～1.5 mg/kg.The 2-0 Surgipro 843 sutures were placed across the base of aneurysm using a strip of teflon felt on either side. The suture line was oriented to reconstruct a relatively normal left ventricular contour. Concurrent CABG was performed. Results 46 cases were reviewed. Left internal mammary artery (LIMA) grafts to the LAD were performed in 39 cases, off-pump with cardiopulmonary bypass in 3, IABP were used in 2. One patient died of left ventricular dysfunction. The other patients had no new myocardial infarctions and were discharged 10 to 14 postoperative days. Conclusion OPCAB and plication of left ventricular aneurysm could obviously decrease the risk of cardiac rupture and avoid the complications of cardiopulmonary bypass.

Objective To explore the value of characteristic manifestation of diffusion-weighted images at 3.0T MR system in cer-ebral disease.Methods 120 patients with cerebral disease diagnosed by MR diffusion-weighted images (fat suppression effect,T2 blackout effect,T2 shine-through effect,T2 washout effect)underwent routine MR scan,including echo planar imaging-diffusion weighted imaging (EPI-DWI)and apparent diffusion coefficient (ADC)map,whose characteristic manifestations of DWI were retro-spectively analyzed.Results 1 5 cases of lipoma and 8 cases without fat lesions were diagnosed with fat suppression effect.13 cases of acute cerebral hematoma,1 1 cases of hemorrhagic cerebral infarction and 1 6 cases of micro bleeding of missed diagnosis or small cavernous hemangioma were diagnosed with T2 blackout effect.1 5 cases of epidermoid cyst,5 cases of choroid plexus cyst were di-agnosed with T2 shine-through effect.1 5 cases of posterior reversible encephalopathy syndrome and 22 cases of brain tumor were di-agnosed with T2 washout effect.Conclusion Comprehensive use of the characteristic manifestation of EPI-DWI and ADC map can help the diagnosis of cerebral disease.

Objective To compare the timeliness, success and mortality rates between the modified carotid artery puncture method ( MCAPM) and standard suture method ( SSM) in the establishment of rat model of a middle cerebral ar?tery occlusion ( MCAO) . Methods Thirty?two male rats were randomly and equally assigned into MCAPM group and SSM group. The MCAO models were established by inserting a thread into the common carotid artery ( CCA) . 24 h after modeling, the rats of the two groups were evaluated with Bederson neurological scores, and the modeling success rate and mortality rate were analyzed. Results The suture insertion times, success rates and mortality rates of the MCAPM vs. SSM groups were (82?3 ±17?4) s versus (164?6 ± 22?0) s (P<0?01), 87?5% versus 68?75% (P>0?05), and 6?25% versus 18?75% (P>0?05). Conclusions MCAPM can be used to establish the rat model of MCAO due to its simplicity, mild wound and feasibility.

Objective To study the CT perfusion features of various lymph nodes in the neck.Methods Dynamic perfusion CT scanning was performed in 83 neck lymph nodes proved by pathology,including tuberculosis lymph nodes, lymphoma and metastatic lymph nodes. The shapes, blood flow modes,and perfusion parameters of these lymph nodes were compared among 3 groups. Statistical analysis of L/T and CT perfusion parameters was performed by one-way ANOVA and LSD test. Results The values of MTT of tuberculosis lymph nodes, lymphoma and metastatic lymph nodes were (28. 13 ±5.08), (31.08 ±5.82),and ( 11.24 ±5.31 ) s,respectively. The MTT of metastatic lymph nodes was statistically lower than that of tuberculosis lymph nodes and lymphoma (P ＜ 0. 05). Their frequencies of marginal blood flow were 5/9,4/19, and 39/55 (70. 9% ), respectively. The frequency of marginal blood flow in the tuberculosis lymph nodes and metastatic lymph nodes was statistically higher than that of lymphoma ( P ＜ 0. 05 ). Their frequencies of central blood flow were 2/9, 11/19, and 9/55 (16.4%), respectively. The frequency of central blood flow in the lymphoma was statistically higher than that of tuberculosis lymph nodes and metastatic lymph nodes ( P ＜ 0. 05 ). Their values of L/T were 1.82 ± 0. 32, 1. 80 ± 0. 39, and 1.84 ± 0. 36,(40. 98 ±6. 62) s,respectively. There were no significant differences in L/T, BF, BV and TTP among tuberculosis lymph nodes, lymphoma and metastatic lymph nodes( P ＞ 0. 05 ). Conclusion CT perfusion,especially combination functional imaging with perfusion images may be helpful in judging the nature of neck lymph nodes.
