CONCLUSlON:There is high prevalence of pterygium in Dongguan area. The prevalence of pterygium is related with age and working environment, but has no relation with gender.

Objective To explore the liver toxicities of the VDLD scheme in children with malignant tumor.Methods In a prospective trial,the levels of serum total protein,albumin, globulin,rate of albumin/globuin alanine aminotransferase,aspartate transaminase,gamma glutamyltranspeptidase,total bile acid and alkaline phosphatase were tested in children with malignant tumour before and after VDLD scheme,and compared with each other.Results The concentration of the serum total bile acid was significantly increased after VDLD scheme than before(P

Objective To analyze the CT findings of endobronchial spread in lung adenocarcinoma. Methods The CT findings of 15 lung adenocarcinomas or bronchioloalveolar carcinomas with endobronchial spread were reviewed,the distribution and the progression of the spread were evaluated.Results All of the primary tumors were consolidation form.The spread lesions distributed in one side of the lung or both sides along the bronchus.The pleural surface was spared.The CT findings of the spread included centrilobular nodules(n=5),tree-in-bud(n=7),acinar nodules(n=2),ground-glass opacities(n=10)and air- space consolidations(n=13)in the first CT examination.5 cases of the spread lesions only presented centrilobular nodules(single form)and 10 cases presented several appearances(complex form).All of the cases were diagnosed as tuberculosis or pneumonia,and antituberculotic or antibiotic therapy was taken with no effect.The follow-up CT scans showed progression in all cases,and the spread lesions with single form became multiple consolidations.The spread lesions with complex form deteriorated faster than the single one. Conclusion Although the CT findings of the endobronchial spread of the lung adenocarcinoma is specific, the clinical history and laboratory examination also are important for the differential diagnosis with tuberculosis and other infectious diseases.

OBJECTIVETo evaluate the effect of long-term Shexiang Baoxin Pill (SXBXP) administration on cardiovascular events in patients with stable angina pectoris (SAP).

METHODSA prospective randomized non-blind parallel controlled study was conducted in the early stage (the first 6 months) of the trial, then a cohort study was succeeded in the later stage. Two hundred patients with SAP, who visited the hospital between May 2005 and June 2006, were selected and randomly assigned to the trial group and the control group, 100 patients in each group. Both were treated with conventional therapy, including treatment for anti-platelet, blood lipid regulating, anti-ischemia, etc, and to patients in the trial group, SXBXP was administered additionally for 2 pills, three times a day by oral intake. The therapeutic course lasted for at least 6 months. All patients were followed up until January 2008, the clinical events and conditions of treatment were recorded. The composite terminal of various cardiovascular events was regarded as the primary endpoint.

RESULTSThe median follow-up time of the study was 2.25 years (ranging from 0.5 to 2.75 years). In the trial group, the occurrence (cases) was 23 for all-clinical event, 20 for primary-clinical event and 9 for angina pectoris event, which were lesser than those in the control group, 33, 29 and 19 cases respectively, showing a significant difference between groups (P < 0.05). The dosage of nitrates used in the trial was decreased more than that before treatment. Besides, all the incidences (cases), in terms of all-cause death (2 vs 5), cardiovascular death (1 vs 2), congestive heart failure (3 vs 4), stroke (2 vs 4), and other clinical (5 vs 6) events, as well as in the need for percutaneous coronary intervention or coronary artery bypass graft (2 vs 4), showed somewhat lowering in the trial group as compared with the corresponding items in the control group, but statistical analysis showed an insignificant difference between them (P > 0.05).

CONCLUSIONLong-term SXBXP administration could reduce the occurrence of angina pectoris events and some other clinical events, and cut down the dosage of nitrates used in patients with SAP.
