Sterols are one of the active classes of compounds in Inonotus obliquus for their effective therapy of many diseases. In field environment, this fungus accumulates large amount of sterols. In cultured mycelia, however, this class of compounds is less accumulated. For analyzing the factors responsible for differing sterol composition, the field-grown and cultured mycelia were extracted with 80% ethanol at room temperature and total sterols were prepared using silicon gel column chromatography followed by identification using either GC-MS or spectroscopic methods. For culturing Inonotus obliquus, the seed culture was grown either in basic medium consisting of glucose (2%), yeast extract (0.5%), KH2PO4 (0.01%), MgSO4·7H2O (0.05%) and distilled water at pH 6.5, or the basic medium supplemented with serial concentrations of AgNO3. The results indicated that field-grown mycelia contained lanosterol and inotodiol (comprised 45.47% and 25.36% of the total sterols, respectively) and other 10 sterols (comprising the remaining 30.17%) including ergosterol biosynthetic intermediates such as 24-methylene dihydrolanosterol, 4,4-dimethylfecosterol, 4-methyl fecosterol, fecosterol and episterol. Column chromatography also led to the isolation of lanosterol, Inotodiol, trametenolic acid, foscoparianol B and a new triterpenoid foscoparianol D in field-grown mycelia. In comparison, the cultured mycelia only contained three sterols with ergosterol as the predominant one (82.20%). Lanosterol only accounted for 3.68%. Supplementing Ag+ into the culture at 0.28 μmol·L-1 greatly enhanced content of lanosterol (accounting for 56.81%) and decreased the content of ergosterol (18.5%) together with the presence of intermediates for ergosterol biosynthesis. These results suggested that the sterol composition in mycelia of the fungus can be diversified by supplementing substances inhibiting enzymatic process towards the synthesis of ergosterol. Harsh growth conditions in field environment (I.e. temperature variation, UV irradiation etc.) can delay the synthesis of ergosterol and hereby diversify the sterol composition in the mycelia of Inonotus obliquus.

OBJECTIVE:To construct the structure equation model for the burden of chronic disease inpatients in primary hos-pital before and after the implementation of zero price policy,and analyze the changes of burden factor loading. METHODS:6 pri-mary hospitals were randomly selected in Danyang,Jiangsu province. The data of hospitalization expenses for chronic diseases(hy-pertension,diabetes,bronchitis)were collected before and after the implementation of zero price policy. Using drug cost,nursing fees,inspection fees and treatment fees as independent variables,hospitalization burden as latent variable,SPSS and AMOS 24.0 software were adopted to establish the model. RESULTS:The burden factor loading of inpatients changed greatly before and after the implementation of zero price policy. χ2=24.586,χ2/df=1.446, RMSEA=0.019,GFI=0.995,AGFI=0.989,CFI=0.988,NFI=0.963 manifested good model fitting. Factor loading of drug cost increased greatly,indicating the burden of inpatients was reduced after the implementation of zero price policy. Factor loading of inspection fees and treatment fees increased significantly,the charac-terization effects of them to the burden of inpatients were enhanced. Factor loading of nursing fees was the lowest,and it had the weakest effects on the burden of inpatients,of which the government should enhance the regulation. CONCLUSIONS:Established model has good reliability and validity. It can reflect the change of burden factor loading of inpatients before and after the implemen-tation of zero price policy.

Background Laser in situ keratomileusis (LASIK) is frequently performed to reduce or eliminate myopic refractive error.Some patients complain of a loss of visual function after surgery even when they have 20/20 visual acuity.One of the reasons is the change of asphericity of the cornea.Objective This study attempts to investigate the short-term changes of the anterior and posterior corneal asphericity after LASIK.Methods One hundred and seven myopic eyes of 54 subjects with the equivalent spherical diopter of -1.30 to -7.50 D who have received LASIK were enrolled in this prospective study.The Q-values of the posterior corneal surface for different corneal diameters (6mm,7mm,8mm and 9mm) were measured with Pentacam preoperatively and 1 month postoperatively.The correlations between Q-value,Q change (△Q),and the mean preoperative spherical equivalent refraction (SE),central corneal thickness (CCT),central ablation depth (AD) and residual bed thickness were investigated.Written informed consents were obtained from all the subjects prior to the clinical trial.Results The Q-values of the anterior and posterior corneal surfaces gradually decreased to negative values with the increase of corneal diameter in myopic eyes.Weak correlations were found between the asphericity of the anterior and posterior corneal surfaces from diameters of 6mm,7mm,8mm and 9mm (r=0.227,0.288,0.303,0.389;P=0.019,0.003,0.002 and 0.000,respectively).No statistically significant correlation was found between Q-value and the diopter of refractive error (P>0.05).Both the anterior and posterior corneal Q-values varied toward the positive direction except that in the 9mm area of the posterior corneal surface at postoperative 1 month(t=-1.495,P=0.138).The increase of the anterior corneal asphericity (△Q) was more obvious than that of the posterior corneal surface and showed a positive correlation with ablation depth and a negative correlation with residual bed thickness.However,no statistically significant correlation was seen between △Q and these two parameters in the posterior corneal surface (P>0.05).Conclusion The shape of the anterior and posterior corneal surface shows more prolateness as the increase of corneal diameter in myopic eyes.Both the anterior and the posterior corneal surfaces have an oblate shift within the ablation zone 1 month after LASIK.
