Traditional Chinese Medicine syndrome analysis on oxaliplatin-induced peripheral neuropathy and clinical efficacy of Bushen Yiqi formula: a prospective randomized controlled study.

OBJECTIVES: To analyze the distribution characteristics of Traditional Chinese Medicine (TCM) syndromes in patients with oxaliplatin-induced peripheral neuropathy (OIPN) and observe the clinical efficacy of Bushen Yiqi formula (, BSYQF) in treating patients with OIPN. METHODS: A total of 89 patients with OIPN were enrolled in this study. The TCM syndrome characteristics were investigated by frequency analysis methodology after collecting and analyzing the TCM syndrome elements of the patients with the OIPN TCM syndrome element scale. Further, 62 cases of cold-dampness obstruction syndrome and kidney-Qi deficiency and cold syndrome were selected and randomly divided into the control group (n = 31) and the treatment group (n = 31). The patients in the treatment group were treated with modified BSYQF, while those in the control group were treated with mecobalamin tablets for 3 weeks. The Levi sensory neurotoxicity score and the neuro-electrophysiological changes were observed before and after the treatment in both groups. RESULTS: The distribution of TCM syndrome types in 89 patients with OIPN were in order of kidney-Qi deficiency and cold syndrome (44 cases), cold-dampness obstruction syndrome (18 cases), Yin deficiency of liver and kidney syndrome (11 cases), blood stasis obstruction syndrome (7 cases), and dampness-heat obstruction syndrome (5 cases). Improvement in Levi sensory neurotoxicity score: After 3-week treatment, the total effective rate in the treatment group was higher than that in the control group (P < 0.05). The subgroup analysis showed that the total effective rate in the treatment group of patients with kidney-Qi deficiency and cold syndrome was higher than that in the control group before and after treatment (P < 0.05). Improvement in nerve conduction velocity: The sensory nerve conduction velocity of bilateral ulnar nerves improved in the control group after treatment compared with that before treatment (P < 0.05). The sensory and motor nerve conduction velocities of the bilateral ulnar and bilateral peroneal nerves improved in the treatment group compared with those before treatment and after treatment in the control group (P < 0.05). CONCLUSIONS: The modified BSYQF had a definite therapeutic effect on the OIPN in patients with kidney-Qi deficiency and cold syndrome and those with cold-dampness obstruction syndrome. It could effectively reduce the grade of peripheral nerve toxicity and improve nerve conduction velocity, and its curative effect was better than that of mecobalamin tablets.

Research Progress on Animal Model for Cancer-related Fatigue / 肿瘤防治研究

Cancer-related fatigue (CRF) is a common symptom which associated with cancer itself or cancer treatments. CRF will not only interrupt the patient's treatment, but also affect the patient's quality of life seriously. To date, the pathogenesis of CRF is still unclear, and recognized effective treatment is lacking. It is the precondition of establishing standardized animal models for CRF to find effective treatments. This paper summarizes the animal model of CRF in order to find suitable methods, and distinguish the effects of different interventions.

Objective To evaluate on novitiate of medical students in center of disease control and prevention(CDC).Methods Junior medical students of Grade 2007 were selected randomly by Cluster sampling method and classified into teaching reform group(novitiate in CDC,n=79) and control group.Traditional lecture and discussion were used in the laboratory of the school to 98 students of the control group,while 79 students of the teaching reform group became CDC trainees.Questionnaire and qualitative interviews were used to evaluate the trainees' preventive medicine cognition,their interest and employment intention.Questionnaire data was proofread and entered in EPIdata (version 3.1),and was analyzed by using Statistical Package for Social Sciences(SPSS version 17.0),and ratio or rate between groups were compared by x2 test,and scores of two groups were compared by using Wilcoxon test.Results In teaching reform group,rate of H1N1 correctly classified as category B was 76.0％,score of knowledge of Programme on Immunization,knowledge of H 1N 1 reporting procedures,knowledge of DOTs strategy,knowledge of chronic non-communicable disease management,and self-interest in preventive medicine was 4.0,4.0,3.0,5.0 and 4.0(points) respectively,and the proportion of regarding CDC as an employment options was 73.3％,respectively higher than 40.4％,2.9,2.9,2.0,4.0,3.8 points and 28.7％ in control group(all P＜0.05).Conclusion Novitiate in CDC is helpful to increasing students' interest in learning preventive medicine,learning knowledge of preventive medicine,and changing employment concept.

Discussion of some problems in studying relationship between sphygmo-diagram and syndrome types or diseases / 中西医结合学报

In contemporary studies of pulse and of the relationship between sphygmo-diagram and syndrome types or diseases, pulse instrument is usually applied to trace the sphygmo-diagram. A comparatively systemic theory about pulse diagnosis has been formed, and it promotes the pulse researching process. But the mechanism of pulse is complicated and the expressive information of pulse is diversity. So it is difficult to record the complicated information of pulse by applying the instrument. In addition, the simplicity in methods of tracing and analyzing sphygmo-diagram and the lack of criterion for syndrome differentiation make it difficult to study the relationship between the sphygmo-diagram and the syndrome types. It's important to lay stress on clinical applying, to promote communication among researchers, to unify the standards of pulse instrument and syndrome differentiation, and to reinforce the research on the relationship between sphygmo-diagram and the syndrome types. The government's support is also needed to promote multi-science cooperation at the same time.
