1.Discussion on Chinese medicine in treating post-infectious irritable bowel syndrome
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(04):-
The pathogenesis of post- infectious irritable bowel syndrome(PI-IBS)involves abnormal intestinal immune barrier, which possibly includes the pathological aspects: Intestinal and systemic changes in T lymphocyte; the change of inflammatory cytokines; a increase in intestinal mast cells and enterochromaffin cells and so on. Treatment by western medicine based largely on symptomatic treatment. TCM thinks that the fundamental organ of the irritable bowel syndrome is the liver. Emotional factors inducing liver dysfunction lead to the symptoms of irritable bowel syndrome. The pathogenesis of IBS is, the disorder of movement of qi in liver and spleen. Stagnation of liver-QI with deficiency of the spleen or disharmony between liver and spleen is the key pathogenesis of post-infectious irritable bowel syndrome. On this basis, in various stages of the disease, there may be a different pathogenesis. As a special type of IBS, the balance of vital qi and evil factors determine the disease progression of PI-IBS, in the treatment course also should not forget dispelling pathogenic factors while strengthening body resistance, tonifying deficiency and removing dampness。
2.Anti-tumor mechanisms of plant alkaloids
Journal of International Oncology 2014;41(4):254-258
Plant alkaloids have anti-tumor activities.In recent years,the anti-tumor mechanisms of plant alkaloid are demonstrated to be related to the block of tumor cell cycle,the induction of tumor cell apoptosis,the inhibition of tumor angiogenesis and multi-drug resistance.In addition,most recently,plant alkaloids are found to inhibit telomerase activity and induce autophagy.Therefore,plant alkaloids may be developed into a sort of potential antitumor drugs.
3.The anti-tumor mechanism of (-)-epigallocatechin-3-gallate
Journal of International Oncology 2012;39(4):255-259
(-)-Epigallocatechin-3-gallate (EGCG),a natural medicine with anti-neoplastic activity,significantly prevent cancers via inhibiting tumor cell proliferation,suppressing angiogenesis and promoting apoptosis,etc.Furthermore,the new discoveries about anti-tumor mechanisms of EGCG in digestive system,reproductive system and respiratory system shorten the course of EGCG application in clinical.
4.New progress of myelodysplastic syndromes in the 55th ASH annual meeting
Journal of Leukemia & Lymphoma 2014;23(1):20-21,29
New progress of myelodysplastic syndomes (MDS) in the 55th ASH annual meeting on 5-azacytidine and decitabine was reviewed.Except in older females,the survival time for a diagnosis of MDS in the United States does not seem to have substantially improved since the introduction of 5-azacytidine into the market in 2004.However,clinical and mechanism data suggest that judicious,mechanism-based application and optimization of these agents will have increasingly meaningful impact.Moreover,these drugs are exemplars of an inspiring alternative to the traditional cytotoxic paradigm and should pave the way for additional relatively nontoxic but broadly effective agents.
5.Research on Relationship between Expression of ??T Cell Subsets and TCM Syndrome Differentiation Type in Aplastic Anemia Patients
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(10):-
Objective:To build up discriminatory formulas for TCM Syndrome Differentiation Type(TCMSDT) of Aplastic Anemia(AA),discuss ??T subset and their relation with discriminatory formulas.Method:Under the cytometry technique,immuno-indexes in peripheral blood of 34 AA patients and 34 healthy persons were detected.Then build up discriminatory formulas to quantify TCMSDT of AA,and to analyze relations between the subset and TCMSDT.Result:Firstly,absolute value of CD45RA~(+),CD3~(+)CD25~(+) and CD3~(+)HLA-DR~(+),CD3~(+)CD25~(+)(%)and CD4~(+)??T(%)are singled out to make up discriminatory formulas,the total correct ratio is 76.5%.Secondly,vs.control,CD4~(+)??T(%)is statistically in deficiency of kidney-yang group(P
6.New progress of allogeneic transplantation in myelodysplastic syndromes in the 55th ASH annual meeting
Journal of Leukemia & Lymphoma 2014;23(2):73-74,78
New progress of myelodysplastic syndomes (MDS) in the 55th ASH annual meeting on allogeneic transplantation were reviewed.Even though the IPSS was developed mainly to determine the prognostic risk in newly diagnosed MDS patients,its predictive value concerning posttransplantation outcome has bcen confirmed in several studies.According to a decision model published a decade ago,patients with intermediate-2 or high-risk MDS by IPSS criteria should be considered for hematopoietic cell transplantation (HCT) at the time of diagnosis if an HLA-matched donor is available at this time.Given the age of most MDS patients,therapeutic interventions are per se often limited to rather nonintensive treatment approaches.This article reviews the current evidence for allogeneic HCT as a therapeutic option in the context of disease-specific characteristics and current available alternative treatments.

Object To investigate the effects of resveratrol (Res) on the proliferation and apoptosis of nasopharyngeal carcinoma cell line CNE-2Z. Methods IC 50 values were detected by MTT assay. The apoptosis was analyzed by flow cytometry (FCM), Hoechst 33258/PI fluorescence staining, and DNA agarose gel electrophoresis. Results After CNE-2Z cells were treated with different concentrations of Res for 24, 48, and 72 h, their IC 50 values were (109.2?7.5), (83.6?6.0), and (54.3?2.8) ?mol/L respectively (P

Objective:To study whether caspase-6 was activated during resveratrol(Res)- induced apoptosis of nasopharyngeal carcinoma cells CNE-2Z. Methods:The cleavage of pro-caspase-6 was analyzed by Western-blot. TTie changes of caspase-6 mKNA was detected by semi-quantitative RT-PCR. The changes of caspase-6 activity was determined by colorimetric assay. Results: After CNE-2Z cells were treated with 0 (control), 25, 50, 100, 200 pmol/L Res for 24 h, respectively, the expression of pro-caspase-6 was decreased with concentration increasing. Caspase-6 active fragment P20(20 kD) appeared at 100 fjtmol/L and was increased at 200 (junol/L.The expression of caspase-6 mR-NA was increased in a concentration-dependent manner ( P

Objective To explore clinical effect and life quality study of Shenyi capsule combined with docetaxel and cisplatin in treatment of advanced breast cancer.Methods 135 cases of advanced breast cancer of Huangshi Central Hospital were collected and diagnosed from July 2013 to December 2014 in accordance with the random number table,were divided into treatment group(n=69) and control group(n=66).Both groups were given regular basis treatment, control group was treated by docetaxel(75 mg/m2,twice a day)and cisplatin(25 mg/m2,once a day), and treatment group combined with Shenyi capsule(20 mg,twice a day)on the basis of control group treatment.4 weeks were 1 course, and all the cases were taken 12 weeks of continuous treatment.Observed and compared the clinical efficiency and life quality of two groups.Results The remission rate of 63.77% in treatment group was higher than control group of 40.91%, difference was statistically significant(χ2 =7.070,P=0.008).After treatment, the SF-36 scale in treatment group significantly increased from ( 54.69 ±8.78 ) to ( 63.87 ±12.08 ) , and higher than that of control group ( 57.95 ±11.95 ) , differences were statistically significant(P<0.05).The adverse reactions in treatment group was lower than control group, difference was statistically significant(Z=2.858,P =0.000).Conclusion The clinical effect in treatment of advanced breast canceris obvious by Shenyi capsule combined docetaxel and cisplatin.It can significantly improve clinical effect and life quality.

Functional dyspepsia is a common functional gastrointestinal disease , however , the cause of functional dyspepsia has not been fully elucidated .Ghrelin is braingut petide , secreted by major endocrine cells of the stomach ( x/A like cells ) .Its recep-tor is widely distributed in the body .It has many kinds of biological effects , such as regulating growth hormone secretion , feeding and energy balance , affecting neuroendocrine and gastrointestinal function and so on .A growing number of studies have shown that Ghrelin in FD has a positive role in increasing the improvement of food intake and generating hunger , promoting gastric emptying .Ghrelin is a new hot spot in the research of FD .
