ObjectiveBased on traditional quality evaluation of Gardeniae Fructus（GF） recorded in historical materia medica， this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics， microscopic features， and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length， diameter and individual fruit weight of wild and cultivated GF， and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF， and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently， the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China， the starch content was measured by anthrone colorimetric method， the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method， the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection（HPLC-ELSD）， and the contents of representative components in them were measured by ultra-performance liquid chromatography（UPLC）. Finally， correlation analysis was conducted between quality traits and phenotypic traits， combined with multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， key differential components between wild and cultivated GF were screened. ResultsIn terms of traits， the wild GF fruits were smaller， exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger， displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF， while the blue-yellow value（b^*） of wild GF was significantly higher than that of cultivated GF. In the microstructure， the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals， while the endocarp contained stone cell class round， polygonal or tangential prolongation， undeveloped seeds were visible within the fruit. In contrast， the mesocarp of cultivated GF contained few calcium oxalate cluster crystals， or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like， with the innermost layer arranged in a grid pattern. Seeds were basically mature， and only a few immature seeds existed in some batches. Regarding primary metabolite content， wild GF exhibited significantly higher total polysaccharide level than cultivated GF（P<0.01）. In category-specific component content， wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF（P<0.01）. Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside， deacetyl asperulosidic acid methyl ester， gardenoside and chlorogenic acid compared to cultivated GF（P<0.01）. Conversely， the contents of genipin 1-gentiobioside， geniposide and genipin were significantly lower in wild GF（P<0.01）. ConclusionThere are significant differences between wild and cultivated GF in terms of traits， microstructure， and contents of primary and secondary metabolites. At present， the quality evaluation system of cultivated GF remains incomplete， and this study provides a reference for guiding the production of high-quality GF medicinal materials.

Objective Through reviewing the herbs,medical books and classic prescriptions of the past dynasties,the herbal examination of Gypsum fibrosum and its analogs was carried out to clarify the relationship between them.The qualitative analysis was carried out by single-point Raman,infrared,near infrared and XRD techniques,the quantitative analysis of the main components was carried out by EDTA titration and Raman surface scanning technique,the elemental analysis was carried out by ICP-OES,and the differences between gypsum and argillite were observed by scanning electron microscope.Results Gypsum fibrosum is mixed with marble,feldspar,north cold-water stone,south cold-water stone and xuanjing stone and so on.Before the Ming Dynasty,there was no differentiation between soft and anhydrite,and after the Ming Dynasty,it was clear that gypsum was soft gypsum and feldspar was anhydrite;in modern times,marble is also made to be gypsum for medicinal use;Feldspar is anhydrite and is no longer made to be used for medicinal use,north cold-water stone is red gypsum,and south cold-water stone is calcite.Gypsum,south coldwater stone is calcite.The peaks of argillite appeared to be buried in the Raman spectrum compared with Gypsum fibrosum,and the original profiles of both infrared and near-infrared were basically the same,and the near-infrared model established by the preprocessing method of the first-order derivatives plus vector normalization(5-point smoothing)could effectively differentiate between Gypsum fibrosum and its analogues,but it could not differentiate between argillite and Gypsum fibrosum with high content.XRD showed that there are differences in the relative intensities of the peaks of argillite and Gypsum fibrosum,and some XRD shows that there are differences in the relative intensities of the peaks of basalt and Gypsum fibrosum,and some of the peaks of basalt are characterized by impurities such as quartz,and the contents of trace elements such as Fe,Mn,Cr,Pb,Hg and As are higher in basalt.The peak shapes of XRD,Raman spectra,infrared spectra and near-infrared spectra of Gypsum fibrosum and calcined gypsum are closer but can still be distinguished,and the Ca content of calcined gypsum is higher than that of gypsum.Commercially available south chrysocolla and stalactite source are carbonate minerals calcite calcite.Spectral detection can not be distinguished,the trace element content is basically the same,but the traits are different.North chrysocolla(red gypsum)is higher than the Fe content of commercially available white gypsum.Raman surface scanning not only can be a qualitative and quantitative determination of minerals such as gypsum and other minerals,and the results of the content of the titration is basically similar,but also to determine the state of Gypsum fibrosum and calcined gypsum calcined water loss status and the degree of calcined gypsum.The results of Raman surface scanning are similar to the titration results.Conclusion This study can provide a scientific basis for the traceability of Gypsum fibrosum,and can better guide the clinical use of medicine and the rational use of resources.

Objective:To assess the predictive value for the risk of cardiogenic stroke (CS) in patients with paroxysmal atrial fibrillation (PAF) using quantification of left atrial appendage early blood stasis (LAA-BS) signs derived from left atrium-pulmonary vein CT examination.Methods:A retrospective analysis of 187 patients with PAF, who were confirmed to have LAA-BS by left atrium-pulmonary vein CT examinations, was conducted at Second Affiliated Hospital of Nantong University from January 2019 to December 2021. The ratio of LAA-BS CT values to ascending aorta (AA) CT values (HU BS/HU AA) and the ratio of LAA-BS volume to LAA volume (V BS/V LAA) were measured at the peak time of AA enhancement, which were used as characteristic quantitative indicators of LAA-BS. Using the median values of HU BS/HU AA and V BS/V LAA as cut-off points for grouping, the differences between the high-ratio and low-ratio groups were compared in terms of general information, clinical characteristics, and imaging characteristics. All enrolled patients were followed up with the primary outcome event of CS occurrence. The differences in the proportion of CS occurrence between the high-ratio and low-ratio groups were compared. The risk stratification analysis of the occurrence of CS in PAF patients was performed using Kaplan-Meier curves. Additionally, the predictive value of HU BS/HU AA, V BS/V LAA and other imaging indices for the risk of CS occurrence was assessed using Cox proportional risk regression models. Results:The incidence of hypertension and the proportion of patients with atrial fibrillation-stroke risk score (CHA 2DS 2-VASc)≥3 in the high V BS/V LAA group were higher than that in the low V BS/V LAA group, and the difference was statistically significant ( P=0.041, P=0.011). The left atrial volume (LAV) in patients in the low HU BS/HU AA group was greater than in the high HU BS/HU AA group, and the difference was statistically significant ( P=0.040). Kaplan-Meier analysis showed a higher incidence of CS in the low HU BS/HU AA group than in the high HU BS/HU AA group ( P=0.012). Similarly, the high V BS/V LAA group had a higher incidence of CS compared with the low V BS/V LAA group ( P=0.019). Subgroup analysis revealed a significantly higher incidence of CS in the subgroup with low HU BS/HU AA and high V BS/V LAA compared to other subgroups (all P<0.05). The Cox proportional hazards regression model, adjusting for confounding factors, identified low HU BS/HU AA and high V BS/V LAA as independent risk factors for CS occurrence in PAF patients ( P=0.005 and P=0.029). Conclusion:The HU BS/HU AA and V BS/V LAA quantified using left atrium-pulmonary vein CT imaging are predictive factors for CS occurrence in patients with PAF. These ratios synergistically contribute to the risk assessment of CS.

Objective To explore the mediating role of intolerance of uncertainty(IU)and moderating role of the negative emotion differentiation in the influence of perceived stress on anxiety among college students from a cognitive perspective.Methods A total of 271 participants were surveyed using the perceived stress scale,intolerance of uncertainty scale,depression anxiety and stress scale(Chinese version),and the test on negative emotional differentiation.SPSS 22.0 was used to perform descriptive statistics and correlation analyses and to test the moderated mediation model.Results Perceived stress affected anxiety and IU played a mediating role-perceived stress could affect anxiety through influencing IU.At the same time,the influence of IU on anxiety could be adjusted through the negative emotion differentiation.The higher the degree of negative emotion differentiation,the lower the degree of anxiety increase(β=0.17,t=5.70,P＜0.01).Conclusion It may be effective to develop training programs to reduce anxiety by regulating perceived stress,increasing acceptance of uncertainty,and improving the negative emotion differentiation,which can help individuals reduce anxiety by perceiving and adjusting anxiety-related emotional or cognitive factors in a timely manner.
