Expression of bcl-2 oncogene in gastric precancerous lesions and its correlation with syndromes in traditional Chinese medicine

AIM: To observe the protein and mRNA expression of bcl-2 oncogene in gastric precancerous lesions (GPL) and to analyze its correlation with syndromes in traditional Chinese medicine (TCM). METHODS: Sixty-seven patients with GPL confirmed by gastroscopy and pathology were studied,including 39 cases of moderate gastric mucosal dysplasia,19 cases of severe gastric mucosa dysplasia, 9 cases of incomplete colon metaplasia. In syndrome differentiation of TCM,17 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by qi stagnation, 21 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by stomach heat, 29 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by blood stasis. Protein and mRNA expression of bcl-2 oncogene were detected by labeled streptavidin biotin (LSAB) immunohist-ochemistry and in situ hybridization respectively. RESULTS: Abnormal expression of protein and mRNA on bcl-2 oncogene was found in GPL,which increased gradually with the course of lesions. In moderate and severe gastric mucosal dysplasia and incomplete colon metaplasia,there was no difference in the expression of bcl-2 oncogene (P>0.05).In different accompanying syndromes, the expression of protein and mRNA on bcl-2 oncogene increased gradually in the following order: deficiency of both qi and yin of the spleen and stomach accompanying qi stagnation→stomach heat→blood stasis. In GPL, compared with accompanying blood stasis, there was an obvious difference in the expression of bcl-2 oncogene between the syndrome of qi and yin deficiency of the spleen and stomach and accompanying stomach heat, so did accompanying qi stagnation (the level of protein: X2=8.45, P<0.05;the level of mRNA: X2=7.35, P<0.05). CONCLUSION: Apoptosis-associated bcl-2 oncogene is abnormally expressed in GPL,which correlates with different accompanying syndromes in TCM.

Clinical Observation on Quality of Life in Coronary Artery Bypass Grafting Patients Treated According to Syndrome Differentiation of TCM

Objective: To evaluate the clinical effect and quality of life (QOL) in coronary artery bypass grafting (CABG) patients treated according to syndrome differentiation of TCM. Methods: Eighty-two CABG patients were allocated in the control group (n = 39) treated with conventional method of western medicine, and the TCM-treated group (n

Multi-central Clinical Research into Treating 80 Cases of Chronic Thrombocytopenia with Qi-supplementing and Yin-nourishing Therapy and Western Medicine

Objective: To probe the effects of qi-supplementing and yin-nourishing therapy (blood-increasing decoction and blood generating powder) on chronic thrombocytopenia. Methods: Two hundred patients with chronic thrombocytopenia were randomly divided into control (n=100) and test groups (n = 100) with Amino-polypeptide as a basic treatment for both. Test group patients consumed a blood-increasing decoction and blood-generating powder for 1-3 months. Improvements in platelet counts and TCM syndrome were observed. Results: One hundred and sixty-four (80 in the test group and 84 in the control group) of 189 total participants were treated for 3 months. The total effective rate in improving TCM syndrome was 95.00% in the test group and 79.76% in the control group (P<0.05). There was significant difference (P<0.05) in the accumulated score of TCM syndrome between the two groups treated at different time points. The total effective rate of platelet counts was 86.25% in the test group and 59.52% in the control group (P<0.05). There was a significant difference in platelet counts before and after treatment in the two groups (P<0.05). There was no significant differences in platelet count between the two groups treated for 1-2 months; however, a significant difference was found between the two groups after treatment for 3 months (P<0.05). Conclusions: After a 3-month treatment of chronic thrombocytopenia patients with qi-supplementing and yin-nourishing therapy, TCM syndrome was improved and platelet counts increased with no obvious side effects, and the quality of life of the participants was enhanced with noticeable long-term curative effects.

Exploration of Syndrome Differentiation Patterns in Coronary Heart Disease Patients during Peri-Operative Stage of Coronary Artery Bypass Graft

Objective: To explore the patterns of Syndrome Differentiation (SD) of coronary heart disease (CHD) patients in peri-operative stage of coronary artery bypass graft (CABG).Methods: One week after operation, thirty-seven CHD patients, who received CABG of internal mammary artery or great saphena vein under conventional general anesthesia with low or middle temperature extracorporeal circulation were differentiated as various syndromes, with the pre- or post-operational EKG, color Doppler echocardiography were done during and after operation. The hemodynamic parameters were monitored.Results: In the CHD patients, 64.9% were differentiated as Qi-Yin deficiency, 67.6% were complicated with phlegm syndrome and 62.2% with blood stasis, suggesting that Qi-deficiency, phlegm and stasis are the basic pathogenetic factors in patients with CABG. Moreover, the peri-operative syndrome was correlated with the condition of coronary artery lesion, heart and lung functions before operation, and the extracorporeal circulation time during the operation.Conclusion: TCM SD conducting in peri-operative stage might be useful in exploring the patterns of syndrome alteration which provided a basis for preventing peri-operative complications and elevating success rate of operation.

Effects of Garlicin on Unstable Angina Pectoris and Its Relationship with Blood Lipid and Granule Membrane Protein-140

Objective: To observe the clinical effects of Garlicin on unstable angina pectoris (UAP) and explore how the Garlicin's effects vary among syndromes as defined by traditional Chinese medicine (TCM).Methods: Fifty-five patients with UAP were randomly divided into the Garlicin group (34 patients) and the control group (21 patients). Each patient was classified according to TCM Syndrome Differentiation as having Cold Syndrome type, Heat Syndrome type, severe blood stasis (SBS) type, and mild blood stasis (MBS) type of UAP. Garlicin 60 mg or nitroglycerin 5 mg was given to the two groups respectively by intravenous drip for 10days as one therapeutic course. The curative effect was evaluated by symptomatic changes and electrocardiogram. The effective rates as well as indexes such as blood lipid, lipoprotein, apolipoprotein, and granule membrane protein-140 (GMP-140) were compared between groups and types. Results: Garlicin and nitroglycerin group did not differ significantly in effective rate, while that of Garlicin group was higher for the Cold Syndrome type than that of Heat Syndrome type (P < 0. 01 ). The high density lipoprotein/low density lipoprotein ratio and apolipoprotein A- I level rose markedly in the former type (P < 0. 05), while an opposite trend was seen in the Heat Syndrome type. Garlicin was more effective in the SBS type than that in the MBS type, and it markedly decreased GMP-140 in the MBS type. Conclusions: Garlicin is effective in UAP, especially the Cold Syndrome and SBS types. Its mechanism may involve improving blood lipid levels and inhibiting platelet activation.

Clinical Observation on Syndrome Differentiation Staging Therapy of Central Serous Chorioretinopathy

Objective: To observe the effect of traditional Chinese medicine in Syndrome Differentiation Staging therapy （SDST） in treating central serous chorioretinopathy （CSC）. Methods: One hundred patients of CSC were divided into two groups, the TCM group and the control group, and were treated with SDST and western medicine respectively. Results: The total effective rate of the two groups was 98 % and 82 % respectively and their mean cure time 35 ± 7.0 days and 39 ± 8.8 days respectively. Comparison between the two groups showed significant difference （P＜0.05）, effect in the TCM group was superior to that in the control group.Conclusion: SDST treatment was helpful in curing CSC. Its basic action is to relieve Qi stagnation and blood stasis, which were taken as the basic physiopathologic change of CSC. And the staging therapy could enhance the therapeutic effect in different stages of the disease.

Studies on Plasma Norepinephrine and EpinephrineContents and Vegetative Nervous SystemFunction in Various Liver Syndrome

Objective: To study the characteristics of plasma norepinephrine (NE) and epinephrine (E) contents alternation and vegetative nervous function disturbance in patients with various Liver Syndrome of TCM.Methods: Subjects were selected on the principle of combination of disease diagnosis and Syndrome Differentiation. Plasma NE and E contents were determined by high performance liquid chromatography (HPLC) and electrochemical detector. The vegetative nervous function were assessed by comprehensive analysis of sympathetic and parasympathetic hyperfunction symptoms, physiologic indexes and physical loading tests.Results: Patients of Liver Excess Syndrome had an elevated plasma NE and E contents and those with the vegetative nervous system disturbance mainly hypersympathetic. On the contrary, patients of Liver Deficiency Syndrome had lowered plasma NE and E contents and those with the vegetative nervous system disturbance mainly hyper-parasympathetic.Conclusion: Plasma NE and E contents and vegetative nervous function disturbance can be taken as the auxiliary laboratory diagnostic indexes for Syndrome Differentiation of Liver Excess and Liver Deficiency.
