OBJECTIVE To investigate the correlation of component content with colorimetric values during the roasting process of Ziziphus jujuba ， and to provide criteria for discriminating the roasting degree of Z. jujuba . METHODS Samples were prepared by dry stir-frying for different roasting times. The eight main components in raw Z. jujuba and the samples stir-fried for different roasting times-namely adenosine， magnoflorine， jujuboside A， spinosin， 6-feruloylspinosin， betulinic acid， oleic acid， and linoleic acid-were quantitativel y analyzed using ultra-performance liquid chromatography. The chromaticity values were determined using a UV spectrophotometer. The correlation and differences between the chromaticity values of Z. jujuba at different roasting times and their components content were analyzed by Pearson correlation analysis， linear regression analysis， principal component analysis （PCA） ， cluster heatmap analysis （CHA）， and partial least squares discriminant analysis （PLS-DA） to clarify the processing endpoint. RESULTS As the roasting time increased， the contents of linoleic acid and oleic acid decreased， while the contents of other components exhibited an increasing trend. Concurrently， the colorimetric value L* and E*ab were observed to decline， whereas the a* value demonstrated a gradual increase. Pearson correlation analysis revealed that L* and E*ab exhibited a significant negative correlation with the contents of adenosine， spinosin， 6-feruloylspinosin， jujuboside A， betulinic acid and magnoflorine （ P ＜0.05）. The results of linear regression analysis indicate that the content of six components, including adenosine， in the medicinal material can be preliminarily predicted by analyzing the colorimetric values of Z. jujuba powder. PCA and CHA successfully classified raw and stir-fried samples. The PLS-DA results indicated that L*， E*ab， a*， linoleic acid content， and oleic acid content were the main parameters that differentiated the color and quality of Z. jujuba at different roasting times. After frying for 9 to 10 minutes， the colorimetric values L* and E*ab decreased to their minimum values and stabilized， while a* remained consistently high with little variation；simultaneously， the concentrations of the six major components， excluding linoleic acid and oleic acid， reached their peak levels. CONCLUSIONS A significant correlation between the colorimetric values of Z. jujuba and the contents of six components， including adenosine， is confirmed. The optimal roasting time range is determined to be 9-10 minutes. Furthermore， the colorimetric value-component content correlation analysis method established in this study proved to be practical and applicable for discriminating the roasting degree of Z. jujuba .

Objective:To analyze the risk factors of anaphylaxis caused by sodium dimercaptopropane sulfonate (DMPS) in patients with hepatolenticular degeneration (HLD) and its predictive value.Methods:The electronic medical records of patients who were hospitalized for the first time in the First Affiliated Hospital of Anhui University of Chinese Medicine due to HLD from January 2019 to December 2021 and received DMPS treatment were collected. The basic information, relevant laboratory test results before the application of DMPS, daily dose of DMPS, and occurrence, treatment and outcome of allergic reactions in patients were recorded. The patients were divided into allergy group and control group based on whether DMPS-related anaphylaxis occurred. The clinical characteristics in patients in the 2 groups were compared. The risk factors of DMPS-induced anaphylaxis were analyzed using binary logistic regression, and the odds ratio ( OR) and its 95% confidence interval ( CI) were calculated. All independent risk factors were merged into joint predictor and the predictive value of individual risk factors and joint predictor for risk of anaphylaxis were analyzed using receiver operating characteristic (ROC) curve. Results:A total of 477 patients were enrolled in the study, including 124 patients in the allergy group and 353 patients in the control group. Among the 124 patients in the allergy group, 80 were male and 44 were female, aged 1-51 years, with 55 patients <18 years of age. Among the 353 patients in the control group, 237 were male and 116 were female, aged 2-66 years, with 106 patients <18 years of age. A total of 191 times of allergic reactions occurred in patients in the allergy group, the main manifestations were pruritus (67 times, 35.1%) and drug-induced dermatitis (58 times, 30.4%). The allergic reactions occurred during the 1st to the 5th course of treatment, with 74 (59.7%) and 31 cases (25.0%) occurring in the 1st and 2nd course of treatment, respectively. DMPS was discontinued in all patients. Of them, 5 patients did not receive any intervention because of mild symptoms and the rest were treated with glucocorticoids and/or antihistamines, and the symptoms of anaphylaxis subsided. The differences in age, DMPS medication history before admission, drug allergy history, and peripheral blood lymphocyte count, ceruloplasmin, alanine aminotransferase (ALT), aspartate aminotrans-ferase, alkaline phosphatase (ALP), γ-glutamyltransferase, lactate dehydrogenase, and blood urea nitrogen levels before DMPS application between the 2 groups were statistically significant (all P<0.05). Binary logistic regression analysis showed that the history of drug allergy ( OR=3.698, 95% CI: 2.233-6.124, P<0.001), the level of ALT before medication ( OR=1.004, 95% CI: 1.000-1.007, P=0.044) and the level of ALP before medication ( OR=1.003, 95% CI: 1.002-1.005, P<0.001) were independent risk factors for allergic reactions caused by DMPS in HLD patients. ROC curve analysis showed that the area under the curve (AUC) of ALT level before medication was 0.613 (95% CI: 0.553-0.673), the cutoff value was 50 U/L, the sensitivity was 0.419, and the specificity was 0.788; the AUC of ALP level before medication was 0.600 (95% CI: 0.537- 0.663), the cutoff value was 202 U/L, the sensitivity was 0.411, and the specificity was 0.816. Allergy history, ALP and ALT levels before medication were converted into joint predictor by logistic regression model. ROC curve analysis showed that the AUC of joint predictor was 0.703 (95% CI: 0.648-0.757), the cutoff value was 0.465, the sensitivity was 0.685, and the specificity was 0.657. Conclusions:The history of drug allergy, the level of ALT and ALP before medication are independent risk factors of anaphylaxis induced by DMPS in HLD patients. The joint predictor has good predictive value for anaphylaxis induced by DMPS in HLD patients.

Objective　A recent study has shown the association between a sulfonylurea receptor gene-1 (SUR1) variant and hyperinsulinemia in normal individuals from a high diabetes risk ethnic group,supporting the hypothesis that the primary insulin hypersecretion may be an antecedent of type 2 diabetes.Methods　To test this hypothesis in Chinese population,we studied the allele and genotype distribution of the polymorphism at -3 position of intron 24 in SUR1 by PCR-RFLP technique in 206 unrelated normal glucose tolerant subjects with strong family history of type 2 diabetes (group A) and 110 normal individuals without family history of diabetes (group B).Results　The frequency of “-3c” allele and “-3cc” genotype of intron 24 in group A was significantly higher than that in group B (64% vs 54%，P=0.004 and 38% vs 24%，P=0.002 respectively).Moreover,in group A, those carrying “cc” genetype had a higher BMI (27.27±6.37 vs 24.99±3.43kg/m2，P＜0.05；27.27±6.37 vs 25.28±2.78kg/m2，P＜0.05),fasting insulin (15.52±10.72 vs 9.27±5.03U/ml,P＜0.01；15.52±10.72 vs 10.79±7.80U/ml,P＜0.05) and 2h insulin levels (76.41±54.02 vs 55.43±49.60U/ml,P＜0.01；76.41±54.02 vs 55.71±40.39, P＜0.05) as well as lower insulin sensitivity ［HOMA(Ri］: 4.00±3.09 vs 2.79±1.32, P＜0.01； 4.00±3.09 vs 2.82±2.94, P＜0.01) as compared with that in carriers of other genotypes (“ct” and “tt”).Conclusion　This study suggested the possibility that the defect in SUR1 gene might contribute to the insulin hypersecretion which might be the cause of subsequent increased body weight and decreased insulin sensitivity.
