[Effects of Guizhi Fuling Decoction on YKL-40 and hs-CRP of patients with non-ST segment elevation acute coronary syndrome].

OBJECTIVE: To investigate the changes of serum levels of chitinase-3-like-1 protein (YKL-40) and high-sensitivity C-reactive protein (hs-CRP) in patients with non-ST segment elevation acute coronary syndrome (ACS), to explore its correlation with its severity, and to observe the effects of Guizhi Fuling Decoction (GFD) on levels of blood lipids, YKL-40, and hs-CRP. METHODS: Recruited were 72 patients with unstable angina (UA) or non-ST segment elevation myocardial infarction (NSTEMI) at Department of Integrative Medicine, First Affiliated Hospital of Xinxiang Medical College from August 2010 to June 2011. They were randomly assigned to the treatment group (36 cases) and the control group (36 cases). All patients were treated by routine treatment, but patients in the treatment group took GFD additionally. The course of treatment was four weeks. According to the severity degree, all patients were graded to four ranks: low-risk group of UA, medium-risk group of UA, high-risk group of UA, and NSTEMI. The levels of YKL-40 and hs-CRP, and the correlation of severity degree were analyzed. Before and after treatment levels of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) were measured. Before treatment, at two weeks, and after treatment the serum levels of YKL-40 and hs-CRP were detected. The relationship of YKL-40, hs-CRP and the severity of the disease were analyzed. RESULTS: Levels of YKL-40 and hs-CRP were positively correlated with the severity of the disease respectively (r = 0.729, P < 0.05; r = 0.655, P < 0.05). The positive correlation also existed between YKL-40 and hs-CRP (r = 0.848, P < 0.05). There was no statistical difference in the levels of blood lipids, YKL-40, or hs-CRP between the two groups before treatment (P > 0.05). Compared with before treatment, the levels of YKL-40 and hs-CRP significantly decreased in both groups after two weeks of treatment (P < 0.05). The levels of TG, TC, LDL-C, YKL-40, and hs-CRP significantly decreased, while the HDL-C level increased in both groups after treatment (P < 0.05). The level of HDL-C in the treatment group was higher, while levels of YKL-40 and hs-CRP were lower after treatment, when compared with the control group (all P < 0.05). CONCLUSION: On the basis of anti-inflammation and adjusting blood lipids by Western medicine, GFD could further reduce the serum levels of YKL-40 and hs-CRP of ACS patients, elevate the HDL-C level, and play anti-atherosclerosis effects.

Relationship between various Chinese medicine types and T-cell subsets in patients with ulcerative colitis.

OBJECTIVE: To investigate the relationship between various Chinese medicine (CM) types and T-cell subsets (CD4(+) and CD8(+)) in the colonic mucous membranes of patients with ulcerative colitis (UC). METHODS: Fifty UC patients were enrolled, after differentiation into four types by CM syndromes, i.e., the internal heat-damp accumulation type (IHDA), the qi-stagnancy with blood stasis type (QSBS), the Pi-Shen yang-deficiency type (PSYD) and the yin-blood deficiency type (YBD). From every patient, 3-5 pieces of intestinal mucous membrane tissues were taken through colonoscopy to determine the levels of the T-cell subsets (CD4(+) and CD8(+)) using immunohistochemical method. The results were compared with those in the normal control. RESULTS: The level of CD8(+)increased and the ratio of CD4(+)/CD8(+)decreased mainly in colonic mucous membranous tissues in UC patients. The level of CD4(+)decreased significantly in IHDA types (P<0.01), but decreased only slightly in the PSYD, QSBS and YBD types. CD8(+)increased significantly in the IHDA types (P<0.01), but only slightly in the other three types. CONCLUSION: The IHDA types of UC are closely related with T-cell subsets. The difference of T-cell subsets in various IHDA types of UC patients has provided a theoretical basis for syndrome differentiation in the CM typing of UC.
