Objective To study the absorption and transportation of flavonoids in Herb Epimedii by using Caco-2 monolayer model. Methods Caco-2 cell monolayer model was used to study the bi-direction transport of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ. The concentration of the five flavonoids in cell culture medium was measured by UPLC and the apparent permeability coefficients (Papp) were calculated. Results The absorptive permeability coefficients (PAB) of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ were 5.91?10-7, 3.22?10-7, 2.76?10-7, 4.23?10-7, and 1.46?10-6 cm/s, respectively. Except baohuoside Ⅰ, the other four flavonodes had lower permeabilities, and the secretive permeabilities (PBA) of all the flavonoids were larger than their absorptive permeabilities. Among them, the PBA of baohuoside Ⅰ was 9.8 times as much as the PAB. Conclusion The results suggest that the intestinal absorption of the five flavonoids is lower, which might have efflux mechanism by transporters, and the absorption of monloglycoside (e.g. baohuoside Ⅰ) is better than that of diglycoside (e.g. icariin) and triglycoside (e.g. epimedin A, epimedin B, and epimedin C).

Objective To compare sensitivity and specificity of the acute physiology,age,and chronic health evaluation system Ⅱ (APACHE Ⅱ),the acute physiology,age,and chronic health evaluation system Ⅲ (APACHE Ⅲ) system in predicting prognosis after cardiac operation.Methods A prospective study of 1 180 consecutive patients entering in a single cardiac postoperative intensive care unit of Anzhen hospital was assigned between November 2013 to January 2014.APACHE Ⅱ and APACHE Ⅲscore was calculated daily at least three days or until death,then compared the calibration and discrimination of the two different system using Hosmer-Lemeshow goodness-of-fit and receiver operating characteristic(ROC) curve.Results In discrimination analysis,ROC value of the first day after operation was(APACHE Ⅱ 0.699 、APACHE Ⅲ 0.734),ROC of the maximum(APACHE Ⅱ 0.836,APACHE Ⅲ 0.862),ROC of the maximum during the first 3 days(APACHE Ⅱ 0.814、APACHE Ⅲ 0.855),ROC of the change between the third day and the first day(APACHE Ⅱ 0.524 、APACHE Ⅲ 0.549).In calibration analysis,we compared the x2 value and overall corrected percentage of the first day value,the maximum value,the maximum value during the first 3 days,the change value between the third day and the first day of the three different system.x2 value of APACHE Ⅱ was(15.688,10.132,8.061,42.253),x2 value ofAPACHE Ⅲ was(13.608,11.196,19.310,47.576).Conclusion APACHE Ⅲ was better than APACHE Ⅱ in prediction of death risk after cardiac surgery.

To investigate the absorption kinetics characteristics of icariin for various intestinal segments.Methods: To establish the situ intestinal perfusion model and to study the absorption of icariin for various intestinal segments.Results: Icariin was metabolized quickly in the four intestinal segments.The permeability coefficient(P*eff) were(4.27?0.28),(5.25?0.17),(1.99?0.09),(0.80?0.03) at duodenum,jejunum,ileum,colon,respectively.Icariside can be detected in the four intestine segments in rats by HPLC.Conclusion: Icariin is metabolized into icariside,and then icariside can be absorbed.

Objective To determine the prevalence and characteristics of the del(GJB6-D13S1830) in Connexin30(Cx30) gene in children with prelingual deafness.Methods Forty-six prelingual deaf children and 30 children with normal comprehension were obtained,and the del(GJB6-D13S1830)in the Cx30 gene were screened by polymerase chain reaction(PCR) in 2 groups.Results Three cases of 46 deaf children were found to have heterozygous del(GJB6-D13S1830) in Cx30 gene.The rest deaf children and the normal controls did not harbor this deletion.Conclusion The heterozygous del(GJB6-D13S1830) in Cx30 gene is one of causes of prelingual deafness.

0.05). Conclusion When TOFR recovers to 0.55,antagonism of residual neuromuscular blockade is still necessary.Different doses of neostigmine may antagonize vecuronium-induced residual neuromuscular blockade,and lower dose of neostigmine(10-20 ?g/kg) is recommended.

Objective To discuss the quantitative diagnosis of stagnation of Qi and blood stasis syndrome in chronic prostatitis. To make diagnosis chart and ensure diagnosis threshold level which provide statistics evidence for syndrome differentiation of TCM. Methods By the statistical ways, 168 cases of chronic prostatitis belong to stagnation of Qi blood and stasis syndrome and 198 cases of non-stagnation of Qi and blood stasis syndrome were investigated. To make a diagnosis chart and ensure diagnosis threshold level by applying the method of the maximum likelihood discriminatory analysis. Results The quantitative diagnosis chart was made and diagnosis threshold level was 26. According to the retrospective and prospective test, its sensitivity, especially degree, coincidence rate, error rate and positive likelihood ratio were 94.64%, 88.89%, 91.53%, 8.47%, 8.52 and 94.28%, 90.32%, 92.42%, 7.58%, 9.74. Conclusion The indexes of the quantitative diagnosis have good objectivity. According to the retrospective and prospective test, the diagnosis chart was proved to be practical.

Objective To evaluate the efficacy of gentamicin solution in transurethral ureteroscopic lithotripsy to prevent postop- erative infection.Methods Prospective clinical randomized control study was conducted.From July 2003 to June 2006,116 ca- ses of ureteral stones at high risk of postoperative infection were randomized into control group or gentamicin group.Patients in gentamicin group received gentamicin solution for washing in the operation.All the patients undergoing operation were followed up for 2 weeks after operation.Diagnosis of postoperative infection was based on clinical manifestations.Results A total of 109 patients received operation in all the 116 cases,including 58 cases in gentamicin group and 51 cases in control group.Thirteen cases of postoperative infection were identified in all the patients receiving operation (11.93%),3 cases in gentamicin group and 10 in control group.The incidence of postoperative infection was significantly different between the two groups (X~2= 5.3342,P=0.0209).Eight cases had positive bacterial culture.Of the microbiological isolates,2 were gram-positive bacteria, 5 gram-negative bacteria and 1 Candida albicans.Conclusions The most common pathogen causing postoperative infection after transurethral ureteroscopic lithotripsy is gram-negative bacteria.The use of gentamicin solution for washing in the operation can reduce the incidence of postoperative infection.
