ObjectiveTo establish the specific chromatogram and quantitative analysis of multi-components by single-marker(QAMS) based on linear calibration using two reference substances(LCTRS), explore the consistency between Hedyotis Herba dispensing granules and standard decoction, and evaluate the quality of the dispensing granules. MethodsHigh performance liquid chromatography(HPLC) specific chromatogram was established based on 15 batches of Hedyotis Herba standard decoction and 10 batches of the dispensing granules, and LCTRS was used to locate chromatographic peaks. The actual retention times of 7 characteristic peaks in the specific chromatogram was measured on 24 different types of C18 columns, taking deacetyl asperulosidic acid and asperulosidic acid as the dual standard compounds, the retention times of the other 5 characteristic peaks were predicted and validated. Based on this, QAMS was developed to determine the contents of four components(deacetyl asperulosidic acid, deacetyl asperulosidic acid methyl ester, asperulosidic acid, and p-coumaric acid). Then, the relative correction factors of deacetyl asperulosidic acid, deacetyl asperulosidic acid methyl ester and p-coumaric acid were calculated using the reference peak of asperulosidic acid in the dual standard compounds, and each component was quantified accordingly. Finally, the consistency between the dispensing granules and standard decoction was assessed by taking extract rate of the standard decoction, consistency of the specific chromatograms, contents and transfer rates of the indicator components as indexes, and the quality of the dispensing granules was evaluated. ResultsThere were 7 common peaks in the characteristic chromatogram of samples of Hedyotis Herba standard decoction and the dispensing granules, and four of them were identified by reference standards, namely deacetyl asperulosidic acid(peak 1), deacetyl asperulosidic acid methyl ester(peak 3), asperulosidic acid(peak 6) and p-coumaric acid(peak 7). The similarity between the dispensing granules and the standard decoction was >0.9. The absolute deviation in the predicted retention time for each component by LCTRS was lower than that of the relative retention time method. The extract rate of the 15 batches of Hedyotis Herba standard decoction ranged from 7.89% to 14.60%, the contents of deacetyl asperulosidic acid, deacetyl asperulosidic acid methyl ester, asperulosidic acid and p-coumaric acid were 6.62-19.70, 3.83-17.99, 1.57-6.69, 1.62-4.52 mg·g-1, and the transfer rates of these components from decoction pieces to the standard decoction were 22.89%-39.60%, 34.03%-62.24%, 24.25%-43.70%, and 40.58%-73.71%, respectively. The extract rate, index component contents and transfer rates from decoction pieces to the three batches of Hedyotis Herba dispensing granules(P1-P3), produced by manufacturer A, were similar to those of the standard decoction prepared from the same batch of decoction pieces, and all fell within the specified range. The contents of the 4 indicator components in 7 batches of the dispensing granules(P4-P10) from manufacturers B-E were all within the range of the content converted from the standard decoction based on the quantity of the dispensing granules. ConclusionThe established specific chromatogram and QAMS based on LCTRS are reasonable and reliable. Based on the evaluation indicators of standard decoction yield, consistency of specific chromatograms, contents and transfer rates of the four index components, the 10 batches of Hedyotis Herba dispensing granules from various manufacturers have exhibited good consistency with the standard decoction, indicating that the current production process is relatively reasonable.

To improve the consistency of outcome documentation and address the potential for outcome reporting bias in clinical trials involving integrative Chinese and Western medicine (ICWM) for ulcerative colitis (UC), we aim to develop a customized core outcome set (COS) that incorporates input from various stakeholders. The study design of this COS has been informed by the Core Outcome Measures in Effectiveness Trials Initiative Handbook, with adherence to the guidelines from the Core Outcome Set-STAndards for Reporting statement and Core Outcome Set-STAndardised Protocol Items recommendations. Five groups of stakeholders will be invited to participate in the development of COS for clinical trials with ICWM for UC, including healthcare professionals, patients, COS developers, COS users, and methodologists. The process will involve five stages: (1) conducting a systematic review of outcomes reported in clinical trials and protocols to develop a list of potential outcome domains; (2) conducting semi-structured interviews to obtain important outcomes; (3) choosing the most important outcomes by conducting three-round Delphi surveys; (4) achieving a consensus in a face-to-face meeting to discuss the final COS; and (5) publication, dissemination and implementation of COS. Consequently, this specialized COS will be applicable to clinical trials involving both traditional Chinese medicine (TCM) and ICWM interventions.

Objective:To investigate the effect of different incubation time of aminolevulinic acid (ALA) on photodynamic inhibition of Propionibacterium acnes biofilms. Methods:Propionibacterium acnes biofilms were formed in 24-well plates with pre-placed cell slides and 96-well plates. The formation of the biofilm structure was observed by confocal laser scanning microscopy (CLSM) , and the growth activity of the biofilm was assessed by the tetrazolium salt XTT assay. The in vitro successfully constructed biofilm models were divided into 6 groups: negative control group receiving neither ALA treatment nor LED radiation, ALA group incubated with ALA alone for 30 minutes, LED group receiving LED radiation alone, ALA-PDT1 group, ALA-PDT2 group and ALA-PDT3 group incubated with ALA for 15, 30 and 60 minutes respectively followed by LED radiation. After the treatment, CLSM was performed to observe the biofilm structure, as well as to determine the dead/living bacteria ratio, and XTT assay to assess the growth activity of the biofilm. Differences among groups were analyzed using one-way analysis of variance and least significant difference- t test. Results:CLSM showed that the Propionibacterium acnes biofilm model was successfully constructed in vitro. The dead/living bacteria ratios were 0.90 ± 0.16, 1.75 ± 0.19, and 2.57 ± 0.32 in the ALA-PDT1 group, ALA-PDT2 group and ALA-PDT3 group respectively, which were significantly higher than the dead/living bacteria ratio in the negative control group (0.31 ± 0.01; t= 55.56, 138.62, 74.64, respectively, all P<0.001) ; the biofilm viability value was significantly lower in the ALA-PDT1 group, ALA-PDT2 group and ALA-PDT3 group (0.35 ± 0.02, 0.26 ± 0.02, 0.18 ± 0.01, respectively) than in the negative control group (0.43 ± 0.00; t= 35.66, 2.64, 110.96, respectively, all P < 0.001) . CLSM showed that the structure of the Propionibacterium acnes biofilm was destroyed under the action of ALA-PDT, and the destruction was aggravated with the prolongation of incubation time of ALA. Conclusion:The prolongation of incubation time of ALA can enhance the inhibitory effect of ALA-PDT on Propionibacterium acnes biofilms.

Objective:To investigate the distribution and influencing factors of the ocular biological parameters related to refractive development in school-age children.Methods:A cross-sectional study was performed.A total of 1 091 children aged 6-12 years old from July, 2017 to August, 2018, resident in downtown of Zhenjiang were enrolled in this study.The corneal radius of curvature (CR) and axial length/corneal radius of curvature ratio (AL/CR) were calculated after AL and corneal curvature (K) were measured by IOL Master.After pupillary dilatation with 0.5% tropicamide, cycloplegic retinoscopy was performed to identify refractive status.According to the spherical equivalent refraction (SER), all right eyes were classified into myopia, hyperopia and emmetropia.The comparison of the above parameters between different genders, as well as among different age groups and different refractive status groups were determined while the relative factors of the biological parameters and refractive status were analyzed by multivariate regression analysis.The study protocol was approved by the Ethics Committee of Affiliated People's Hospital of Jiangsu University (No.K-20190153-W).Results:There were statistical differences in AL, SER and AL/CR value among different age groups ( F=32.34, P<0.01; F=33.69, P<0.01; F=2.19, P=0.04), which showed that refractive status shifted to myopia as well as AL and AL/CR value were increased with age.Compared with the girls, the boys had significantly longer AL, greater CR, greater AL/CR value, and smaller K ( t=7.58, P<0.01; t=-7.48, P<0.01; t=-8.08, P<0.01; t=-2.14, P=0.03). There were statistical differences in AL and AL/CR value among different refractive status groups ( F=192.68, P<0.01; F=143.15, P<0.01). The myopia group had longer AL and greater AL/CR value than the other two groups.Children whose parents were not myopic and children who had outdoor activities more than 14 hours per week and did homework less than 20 hours per week and children who slept more than 9 hours per day had shorter AL, smaller AL/CR value, and were more inclined to hyperopia or emmetropia.The results of multivariate regression analysis suggested that children aged from 6-12 years old with older age, female, increased height, parental myopia, and more time in homework or less time in outdoor activities per week may be more likely to have myopia, and longer AL or bigger AL/CR value was correlated with older age, male, greater body mass index (BMI), increased height, myopia conditions of parents, more time of doing homework, and less time in outdoor activities. Conclusions:The SER shifts to myopia with age in 6 to 12-year-old school-age children in the downtown of Zhenjiang.And there are significant differences in AL, CR and AL/CR value between boys and girls.Female, older age, increased height, more time in homework, less time in outdoor activities, and parental myopia are associated with more negative SER.
