1.Discussion of tumor treatment from the theory of ascending and descending activities of qi.
Chinese Journal of Integrated Traditional and Western Medicine 2015;35(1):104-106
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.

Objective To analysis the outcome of gastroscopy and B ultrasonography in patients of post hepatitis cirrhosis with portal hypertension, and to evaluate the degree of cirrhosis in clinic and affording suggestions in preventing complication. Methods One hundred and ninety two cirrhosis patients with portal hypertension were divided into three groups : mild, moderate and severe group based on the extent of esophageal varicosis. By estimating the diameter of portal vein, thickness of spleen and width of splenic vein in three groups to investigate their correlation with the extent of cardio-esophageal varicosis. Results The incidences of gastric varices in these three groups have prominent difference,The severer the degree of esophageal varices , the higher the incidence of gastric varices. According to the different degree of esophageal varices, the diameter of portal vein,thickness of spleen,diameter of splenic vein are differed. There is linear relation between thickness of spleen and diameter of splenic vein. Conclusion Diameter of portal and splenic vein, thickness of spleen,can provide valuable suggestion in predicting the presence of portal hypertension,but further confirmation is based on the result of gastroendoscopy.

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 investigate the influence of high-voltage electrical burn on the throm-bomodulin (TM), protein C (PC), protein S (PS) and D-Dimer (D-D) in SD rats. Methods One hundred and twenty healthy SD rats were divided into the fake high-voltage electrical burn groups (FHEB), high-voltage electrical burn groups (HEB) according to the random number table, with 60 rats in each group. Ten rats were taken from each group at 15 minutes before injury. Plasma were collected from heart blood. Fifty SD rats of HEB group with voltage regulator and experimental transformer. The remaining fifty SD rats of FHEB group were sham injured with the same devices without electric current. At 5 minutes and 1, 2, 4, 8 hour (s) post injury, 10 rats of every group were randomly chosen at each time point for observation of the concentrations of TM, PC, PS and D-D. Plasma were collected from heart blood. Data were processed with analysis of variance of factorial design and LSD test. Results Compared with the FHEB group, the concentration of TM from 5 minutes to 8 hours post injury in HEB group was higher significantly (P < 0.05). Exception of the concentrations of PC and PS at 15 minutes before injury, the concentrations of PC and PS were lower than those of FHEB group (P < 0.05). The concentration of D-D in HEB group peaked at 8 hours post injury in (173.05 ± 4.08) ng/mL. Conclusion High-voltage electrical burn at early stage can increase the concentrations of TM, D-D, as well as decrease the concentrations of PC and PS, which are not only causing the vascular endothelium damage but also possessing serious effect on the thromboplastin function of SD rats.
