OBJECTIVETo investigate the difference in the vulnerability of carotid atherosclerotic plaques in patients with unilateral and bilateral intraplaque hemorrhage (IPH).

METHODSA retrospective analysis was conducted among 44 patients with unilateral IPH (30 cases) or bilateral IPH (14 cases) in the carotid plaques detected by magnetic resonance imaging (MRI) in our hospital between December, 2009 and December, 2012. The age, maximum wall thickness and incidence of fibrous cap rupture were compared between the two groups.

RESULTSCompared with those with unilateral IPH, the patients with bilateral IPHs had a significantly younger age (66.6∓9.4 years vs 73.7∓9.0 years, P=0.027), a significantly greater maximum plaque thickness (6.3∓1.9 mm vs 5.0∓1.3 mm, P=0.035) and a higher incidence of ulcers (50% vs 13.3%, P=0.025). Logistic regression analysis revealed a significant association between bilateral IPHs and the occurrence of ulcer with an odd ratio (OR) of 6.5 (95% confidence interval [CI]: 1.5-28.7, P=0.014). After adjustment for gender in Model 1, bilateral IPHs were still significantly associated with presence of ulcer (OR=5.7, 95%CI: 1.1-29.2, P=0.036). But after adjustment for age (P=0.131) or maximum plaque thickness (P=0.139) in model 2, no significant correlation was found between bilateral IPHs and the presence of ulcer.

CONCLUSIONCompared with patients with unilateral IPH, those with bilateral IPHs are at a younger age and have a greater plaque burden and a higher incidence of fibrous cap rupture, suggesting a greater vulnerability of the carotid plaques in patients with bilateral IPHs.

OBJECTIVETo evaluate the implication of Fletcher and Miettinen biologic potential grading criteria in native localized gastrointestinal stromal tumors (GISTs).

METHODSTwo hundred and twenty localized GISTs with complete clinicopathologic and follow-up data were evaluated for their biologic potential by Fletcher and Miettinen grading criteria. The implication of the two grading criteria were compared by survival analysis.

RESULTSEvaluated by Fletcher grading criteria, the overall and disease-free survival rate of high risk GISTs was lower than that of very-low, low and intermediate GISTs; while the overall and disease-free survival rate of very-low, low and intermediate risk GISTs had no statistical diffence. In the high risk GISTs, the overall and disease-free survival rate of small intestinal and rectal GISTs was lower than that of gastric GISTs; while in the intermediate risk GISTs, the disease-free survival rate of small intestinal GISTs was lower than that of gastric GISTs. Evaluated by Miettinen grading criteria, the overall and disease-free survival rate of high risk GISTs was lower than that of very-low, low and intermediate GISTs; while the overall and disease-free survival rate of very-low, low and intermediate risk GISTs had no statistical difference. In the risk subgroup of GISTs, the overall and disease-free survival rate of gastric, small intestinal and rectal GISTs had no statistical difference.

CONCLUSIONSFletcher grading criteria is simple and easy to use; while Miettinen grading criteria for evaluating biological potential by anatomic site is more critical and has important reference implication for the selection of high risk patients for targeted adjuvant treatment.

OBJECTIVETo study the therapeutic effect of Weicao Capsule (WCC) on gout.

METHODSTwo hundred gout patients were assigned to two groups. The treated group was treated with WCC and the control group was treated with Tongfengding Capsule. Both groups were given the respective treatments orally 3 times a day, 2 capsules each time with 2 weeks as one course and all patients received 2 successive courses of treatment. Changes of blood beta(2)-microglobulin (beta(2)-M), hemoglobin (Hb), 24 h urinary protein (24 h UP), pH value of urine and blood uric acid (BUA) as well as kidney function were observed.

RESULTSAfter treatment, level of beta(2)-M got lowered significantly, Hb and 24 h UP, blood urea nitrogen, serum creatinine and the clearance rate of creatinine, as well as blood lipids all improved obviously in the treated group (all P<0.01), while these parameters remained unchanged in the control group (P>0.05). The pH value of urine was improved in both groups showing an insignificant difference between them (P>0.05). BUA was decreased in both groups with a decrease to a larger extent in the treated group (P<0.01). The total effective rate was 87% in the treated group, which was superior to that in the control group (62%, P<0.05).

CONCLUSIONWCC has a favorable therapeutic effect on gout and its mechanism of action for improving renal function and reducing urinary protein could be related with the lowering of blood beta(2)-M, BUA and lipids.
