Post-stroke depression (PSD) is a common complication of stroke. Its patogenesis is complex, mainly including the mechanisms of neurobiotogy and social psychology. So far, there has been no uniform conclusion both at home and abroad. Now it is considered that PSD is the results of comprehensive effect of various neurobiology and social psychology, and its onset is in accordance with the bio-psycho-social medical model.

Serum KL-6 is a category of glycoprotein coded by the epithelium of sticky protein 1(MUC1) gene,which has already been regarded as an indicator of interstitial lung diseases,and later found highly expressed in part of malignant tumor patients.In recent years,studies has found that serum KL-6 is associated with the incidence of radioactive pneumonia,and monitoring serum KL-6 can predict the occurrence of radioactive pneumonia as well assess the severity and prognosis of disease.

Objective To investigate the pharmacokinetic profiles of baicalin and wogonoside in diabe-tic rats in vivo,which are two major constituents in Huanglian-Jiedu Decoction(HJD).Methods The diabetic rats were induced by ip administration of streptozotocin(STZ).After the establishment of the method and the set-up of diabetic rats,the pharmacokinetic profiles of baicalin and wogonoside were investigated.Diabetic and normal rats were ig HJD extract,and then the blood samples were collected at the given time points.Contents of baicalin and wogonoside in diabetic and normal rat plasma were assayed by HPLC-UV method.The pharmacokinetic parameters(except Cmax and tmax) were analyzed by noncompartmental method.The area under the serum concentration-time curve(AUC0-t) was calculated using trapezoidal rule to the last point.Moreover,the presystemic metabolism of baicalin was investigated and compared to explore the pharmacokinetic difference by fermentation of baicalin in feces suspensions of normal and diabetic rats,respectively.Results The pharmacokinetic parameters of baicalin in normal and diabe-tic rats were:(4.50?1.92) and(7.5?1.0) h for tmax 2;(2.83?0.25) and(9.54?2.87) ?g/mL for Cmax1,(2.56?0.63) and(6.58?1.15) ?g/mL for Cmax2;(37.58?7.57) and(92.75?24.62) ?g?h/mL for AUC(0～24),(6.6?2.4) and(12.64?3.35) h for t1/2,respectively.And the pharmacokinetic parameters of wogonoside in normal and diabetic rats were:(5.5?1.0) and(8.00?1.63) h for tmax 2;(1.36?0.17) and(6.16?1.40) ?g/mL for Cmax1;(1.58?0.17) and(4.11?0.76) ?g/mL for Cmax2;(27.02?3.72) and(58.16?16.43) ?g?h/mL for AUC(0～24);(9.72?2.24) and(7.89?1.63) h for t1/2,respectively.The results indicated that Cmax1,Cmax2,AUC(0～24) of baicalin and wogonoside were significantly enhanced and t1/2 of baicalin was remarkably extended when compared with the normal rats.And the results also revealed that baicalin contained in HJD hydrolyzed more rapidly when incubated in the feces suspension of diabetic rats than in that of normal rats.Conclusion The results indicate that the pharmacokinetic difference of baicalin between diabetic and normal rats may result from the presystemic metabolism of baicalin.

Objective To evaluate the anatomic relationships between the portals and radial nerve of three different operations of antrolateral approach elbow arthroscopy.Methods The dissections were pedormed in 10 formalin soaked adult cadaver elbows.The distances from the three different antrolateral portals to the radial nerve in extension and flexion 90° position were measured.The portal A was located at 3 cm distal and 1 cm anterior to the lateral epicondyle;the portal B was located at 2 cm distal and 2 cm anterior to the lateral epicondyle;the portal C,1 cm distal and 1 cm anterior to the lateral epicondyle.Results The nearest distances from the anterolateral portal A,B,and C to the radial nerve in extension position were (2.30 ± 0.95) mm,(3.00 ± 1.56) mm,and (3.60 ± 1.65) mm,with significant differences (F =11.097,P =0.001).Statistical difference in distances from the anterolateral portal to the radial nerve between portal A and C was found (P =0.006).No statistically significant difference was seen between A and B or B and C (PA-B =0.134,PB-c =0.072).The distances from the anterolateral portal A,B,and C to the radial nerve in flexion 90° position were (4.40 ± 2.01) mm,(6.10 ± 1.79) mm,and (7.90 ± 1.85) mm,with significant differences (F =54.775,P =0.000).There were statistically significant difference among the three approaches (PA-B =0.000,PA-c =0.000,PB-c =0.002).The distances increased when the position changed from extension to flexion 90° for portal A (t =-5.161,P =0.001),portal B (t=-8.188,P=0.000),and portal C (t =-10.167,P =0.000).Conclusion The anterolateral portal 1 cm distal and 1 cm anterior to the lateral epicondyle is the safest apporach.
