3.Analysis and Treatment in Multiple Sclerosis with Pain Symptom
Chinese Journal of Rehabilitation Theory and Practice 2010;16(8):733-735
Objective To explore the diagnosis and treatment in multiple sclerosis with pain symptom.MethodsThe clinical data of 362 patients suffered from multiple sclerosis with pain symptom from January 1999 to December 2009 were analyzed retrospectively.ResultsPain symptom could result from different causes. Acute radicular pain and Lhermitte's sign were common in the acute pain syndromes as dysaesthetic extremity pain and painful spasticity in chronic pain syndromes. Individual therapy of selected cases showed a benefit of decreased pain symptom.ConclusionPain is a common clinical symptom of multiple sclerosis. Individualized therapeutic decisions could relieve symptom and improve outcome.
4.Analysis on Compatible Mechanism of Shanyao, Fuling and Baishu in TCM Cosmetology
World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(1):207-209
This study was aimed to explore the compatible mechanism of Shanyao, Fuling and Baishu in traditional Chinese medicine (TCM) cosmetology. Based on compatible principles, combination characteristics and modern relat-ed researches, the authors made an in-depth analysis on the modern scientific meaning and clinical application of Shanyao, Fuling and Baishu. The results showed that the compatibility of Shanyao, Fuling and Baishu was mainly used as a compatible group in TCM cosmetology. It was concluded that the compatible mechanism of Shanyao, Fuling and Baishu was flexible, which can be widely used in the clinical practice.
5.Analysis on Processing Methods of Dioscorea opposita Thunb. from the Aspect of Formula
World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(8):1866-1868
This study was aimed to analyze the influence of Dioscorea opposita Thunb. by processing methods from the aspect of formula. The search was made on formulae containing Dioscorea opposita Thunb. from the classic book For-mula Dictionary of Traditional Chinese Medicine. Processing methods were analyzed and shown with charts by EXCEL. The results showed that the most frequently used processing methods for Dioscorea opposita Thunb. were stir-heating, dry and crude in the clinical practice. Among them, the stir-heating Dioscorea opposita Thunb. was good at reinforcing the spleen and the kidneys. The crude produce was good at tonifying the lungs. And the dry product was good at rein-forcing the kidneys. It was concluded that the processing methods had obvious influence on the clinical function of Dioscorea opposita Thunb., which can be used as reference of more value for the clinics and health cultivation.
6.Research progress in the anti-cancer effect of metformin
Tianjin Medical Journal 2017;45(7):767-771
The incidence of malignancy tumors has increased significantly recent years in patients with type 2 diabetes mellitus (T2DM).As the first-line oral medicine of T2DM,in addition to the safe and effective hypoglycemic effect,metformin can reduce the incidence and mortality of cancer,and improve the prognosis in T2DM patients.While the exactly anti-tumor mechanisms of mefformin is not yet clear,which might be the inhibition of proliferation and promotion of apoptosis of tumor cells mainly by acting on an adenosine monophosphate activated protein kinase (AMPK) and microRNAs (miRNAs).And metformin can inhibit migration and invasion of tumor cells,as well as strengthen the effects of chemotherapy drugs.This article reviews the recent research progress of clinical and epidemiological studies and anticancer mechanisms of metformin.
7.The cognitive-behavioral group therapy design on the college students of learing burnout
Chinese Journal of Medical Education Research 2003;0(04):-
Nowadays a large number of domestic researches have shown the degree of learning burnout,the causes,manifestations and the distribution,but there are only one or two cases focusing on empirical research of Group Counseling.In Eriksson's view,the university period is a critical stage to obtain a sense of intimacy and avoid isolation,and the group counseling have great significance in helping students improve the character and get a sense of intimacy.Therefore,based on the literature and interviews,the author use in this study the cognitive-behavioral group therapy to help the students form a new cognitive concepts,behavior and attitude,and improve their self-efficacy.

Objective To investigate the relationship between high sensitive C-reactive protein(hs-CRP) and cardiac function in patients with dilated cardiomyopathy(DCM). Methods We compared the differences of NYHA classes,left ventricular ejection fraction(LVEF) and left ventricular end diastolic diameter (LVEDD) between normal hs-CRP group and elevated hs-CRP group,and analyzed hs-CRP levels of different NYHA classes,then investigated the correlation between hs-CRP and LVEF and between hs-CRP and LVEDD. Results The NYHA stage,LVEF,LVEDD were 2.06?0.90,(38.58?5.98)% and 58.94?6.14mm respectively in normal hs-CRP group,while those were 2.89?0.88,(33.46?6.55)% and 66.87?9.34mm in elevated hs-CRP group,and there were significant differences between the two groups.The hs-CRP was 2.66?1.80mg/L in NYHAⅠgroup,while that was 5.02?3.27mg/L in Ⅱgroup,5.25?3.18mg/L in Ⅲ group,and 8.84?2.60mg/L in Ⅳ group.Levels of hs-CRP in Ⅱgroup and Ⅲ group were both significantly higher than those inⅠgroup(P
