ABSTRACT

Traditional medicine endows medical staff with the role of "moral person";however,with the development of market economy,the role of medical staff has gradually changed to "economic person" in medical activities.Under the role of "economic person",there is an increasing number of medical disputes and injuries of medical staff,with more and more serious consequences.This article analyzes the behavior characteristics of the rights and obligations of "moral person" and "economic person" and the causes of medical disputes under the role of "economic person".Since the lack of honesty has become the product of the new role of medical staff,patients have a doubtful attitude towards medical staff,and the defects in system guidance and management system make it more difficult to settle medical disputes.This article provides a new perspective for building a harmonious doctor-patient relationship and puts forward the hypothesis of "honest economic person",so as to achieve the dialectical unity of the dual identities of "moral person" and "economic person".Under the role of "honest economic person",adherence to honesty and trustworthiness,pursuit of maximum medical benefits,emphasis on the social benefits of medical treatment,and material and spiritual incentives for medical staff can help to alleviate the conflict of interests between doctors and patients and reduce medical disputes.

ABSTRACT

Objective To establish a mini-column centrifugation-HPLC method to determine the entrapment efficiency of levodopa-loaded PEGylated-solid lipid nanoparticles.Methods A dextran gel(Sephadex G-50) mini-column centrifugation was employed to separate the free drug from solid lipid nanoparticles.The content of levodopa was qualified by HPLC.Results Under the applied chromatographic condition,the excipients had no influence on the determination of levodopa.A calibrated linear of levodopa concentration was within 10.54-527.00 μg·mL-1.The recoveries of high,medium and low concentrations of levodopa were 99.13%,99.51% and 99.04%(RSD were 1.25%,1.91% and 1.71%), respectively.The free levodopa was well separated from solid lipid nanoparticles by using mini-column centrifugation.The addition of blank solid lipid nanoparticles recovery was 98.84% with RSD of 0.80%(n=3).The average adsorption rates of the three concentrations of free levodopa were 100.00%,98.75% and 98.56%(RSD were 0.00%,0.19% and 0.18%,n=3),respectively.The adsorption rate of the physical mixtures of three different concentrations of drugs and empty PEGylated solid lipid nanoparticles were 99.68%,98.46% and 99.21%(RSD were 1.52%,0.23% and 0.21%),respectively.Conclusion The method was simple,accurate and reproducible,which can be used for determination of the entrapment efficiency of levodopa-loaded PEGylated-solid lipid nanoparticles.

ABSTRACT

Objective:To investigate the azole susceptibility of Candida albicans (C. albicans) from vulvovaginal candidosis patients and to analyze the relationship between ERG11 gene mutations in these isolates and azole resistance. Methods:Three hundred and two clinical isolates of Candida species were collected. Azole susceptibility was tested in vitro in microdilution studies. The ERG11 genes of 17 isolates of C. albicans (2 susceptibles, 5 dose-dependent resistants and 10 resistants) were amplified and sequenced. Results:Of the 302 isolates collected, 70.2%were C. albicans, of which 8.5%, 3.8%and 4.2%were resistant to fluconazole, itraconazole and voriconazole, respectively. In total, 27 missense mutations were detected in ERG11 genes from resistant/susceptible dose-dependent isolates. Among them, Y132H, A114S, and Y257H substitutions were most prevalent and were known to cause fluconazole resistance. G464S and F72S also has been proved to cause fluconazole resistance. Two novel substitutions (T285A, S457P) in hotspot regions were identified. Conclusions:Twenty seven mutations in the ERG11 gene were identified in azole-resistant C. albicans isolates, which indicated a possible relation with the increase in resistance to azole drugs and the recurrence of vulvovaginal candidosis. The relationship of two novel substitutions (T285A, S457P) with fluconazole resistance needs to be further verified by site-directed mutagenesis.

ABSTRACT

Intraventricular hydrodynamics is considered an important component of cardiac function assessment. Vector flow mapping (VFM) is a novel flow visualization method to describe cardiac pathophysiological condition. This study examined use of new VFM and flow field for assessment of left ventricular (LV) systolic hemodynamics in patients with simple hyperthyroidism (HT). Thirty-seven simple HT patients were enrolled as HT group, and 38 gender- and age-matched healthy volunteers as control group. VFM model was used to analyze LV flow field at LV apical long-axis view. The following flow parameters were measured, including peak systolic velocity (Vs), peak systolic flow (Fs), total systolic negative flow (SQ) in LV basal, middle and apical level, velocity gradient from the apex to the aortic valve (ΔV), and velocity according to half distance (V1/2). The velocity vector in the LV cavity, stream line and vortex distribution in the two groups were observed. The results showed that there were no significant differences in the conventional parameters such as left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD) and left atrium diameter (LAD) between HT group and control group (P>0.05). Compared with the control group, a brighter flow and more vortexes were detected in HT group. Non-uniform distribution occurred in the LV flow field, and the stream lines were discontinuous in HT group. The values of Vs and Fs in three levels, SQ in middle and basal levels, ΔV and V1/2 were higher in HT group than in control group (P<0.01). ΔV was positively correlated with serum free thyroxin (FT4) (r=0.48, P<0.01). Stepwise multiple regression analysis showed that LVEDD, FT4, and body surface area (BSA) were the influence factors of ΔV. The unstable left ventricular systolic hydrodynamics increased in a compensatory manner in simple HT patients. The present study indicated that VFM may be used for early detection of abnormal ventricle contraction in clinical settings.
