Methods346 cases of the treatment group (175 cases of erosive type and 171 cases of bullous type) were treated with soaking therapy by traditional Chinese medicine and 335 cases of the control group (170 cases of erosive type and 165 cases of bullous type) were treated with 3% Clotrimazolum ointment. Effects of two groups were compared.Results Effect of the treatment group was obviously more superior to that of the control group (P<0.0001). ConclusionsIt shows easy and effective that patients with athlete's foot were treated by soaking therapy with traditional Chinese medicine.

Objective To study the correlations between diopter,axis length,cornea curvature and thickness in myopia patients. Design Prospective case series.Participant 300 myopic patients who were ready for LASIK.Method 300 myopic patients who were ready for LASIK were selected randomly.They were divided into four groups according to the diopter of myopia:low myopia group (≤-3.00D)41 cases,medium myopia group(＞-3.00D,≤-6.00D)130 cases,high myopia group(＞-6.00D,≤-9.00D)95 cases,and super myopia group(＞-9.00D)34 cases.The axis length,cornea thickness,cornea eurvture and diopter of myopia were detected. Through analysis of variance(ANOVA),Pearson correlation analysis and linear regression analysis,the correlations between axis length, cornea thickness,curvature and diopter of myopia were made out in four groups.Main Outcome Measure Diopter of myopia,cornea curvature,axis length of eye and central cornea thickness.Result The axis length of low myopia group,medium myopia group,high myopia group and super myopia group was(24.32?1.73)mm,(25.33?1.49)mm,(26.04?1.92)mm,(27.47?2.57)mm respectively. There were obvious differences of axis lengths between four groups(P=0.000).The cornea curvature in high myopia group was obviously different from those in low myopia group and medium myopia group.There were no significant differences of cornea thickness among four groups(P=0.409).The axis lengths of eyes respectively had correlations with diopters(r=0.734,P=0.000),vertical and horizontal cornea curvatures(r=-0.312,P=0.000;r=-0.328,P=0.000).Conclusion The main effective factor on the diopter of myopia is the axis length for most patients.For the patients with high myopia,the cornea curvature is another effective factor.With the increase of axis length,the cornea curvature decreases,and the cornea turns flatter.(Ophthalmol CHN,2006,15:321-323)

Objective: To explore influence of bisoprolol on neuroendocrine factor levels in patients with chronic heart failure (CHF), and its therapeutic effects.Methods: A total of 116 CHF patients, who were treated in our department from Jan 2014 to Nov 2015, were selected.According to random number table, they were randomly and equally divided into routine treatment group and bisoprolol group.Left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDd), 6min walking distance (6MWD), serum levels of brain natriuretic peptide (BNP), endothelin (ET) and atrial natriuretic peptide (ANP) before and three months after treatment, and therapeutic effect were compared between two groups.Results: There were no significant difference in above indexes between two groups before treatment, P>0.05 all.Compared with routine treatment group after three-month treatment, there were significant rise in LVEF [(28.13±4.16)% vs.(36.02±5.14)%] and 6MWD [(245.74±44.62)m vs.(315.23±53.12)m], significant reductions in LVEDd [(62.73±10.14)mm vs.(52.82±9.47)mm], serum levels of BNP [(424.51±62.26) ng/ml vs.(324.35±50.46) ng/ml], ET [(80.14±13.25) ng/ml vs.(57.91±10.32) ng/ml] and ANP [(233.24±42.35)ng/ml vs.(164.83±31.26) ng/ml] in bisoprolol group, P<0.05 all.Compared with routine treatment group, there was significant rise in total effective rate (72.4% vs.86.2%) in bisoprolol group, P=0.04.Conclusion: Bisoprolol can significantly reduce BNP, ET and ANP levels, then delay ventricular remodeling and improve cardiac function in patients with chronic heart failure.The therapeutic effect is significant, which is worth extending.

Objective: To investigate the effect of Fu Zheng Hua Yu-319 Recipe on hepatic sinusoid capillarization in the rat of hepatic fibrogenesis. Methods: Hepatic fibrosis model rats were induced by intraperitoneal injection of dimethyl nitrosamine (DMN). thrice a week for 4 weeks, and they were divided into the treatment group which were treated with Fu Zheng Hua Yu-319 Recipe for 4 weeks, and the model control group. Serum and hepatic tissue were taken for examination of pathohistology, microstructure by electron microscopy, immunohistochemistry, and hydroxyproline content in the liver tissue and hepatic function. Results: In the normal group, peripheral cytoplasma of endothelial cells in the hepatic sinusoid is very thin with a lot of small fenestra, and no basement membrane under endothelium was found. In the model group, crookedness and stricture of the hepatic sinusoid were found , and the fenestra in cytoplasma of the endothelial cell reduced or disappeared with obvious basement membrane, and hemorrhage necrosis in the liver tissue could be found, with a great proliferation of connective tissue in the portal area, and fibrous septum extended towards into the lobuli, the content of hydroxyproline (HYP) in the liver tissue increased significantly. The VI factor-related antigen, a-actin of smooth muscle, LM and type IV collagen positive staining on the hepatic sinusoid wall increased significantly with a wider range as compared with the normal rat. In the treatment group, the extents of crookedness and stricture of hepatic sinusoid and reduction and disappearence of endothelial fenestra were lower, with thiner or discontinuous basement membrane, and a part of hepatic sinusoid construction approached to normal, and degeneration and necrosis of hepatic cells were mild and fibrous septum in the liver tissue decreased significantly, and HYP content decreased significantly (P
