ObjectiveTo explore the changes in color, odor and chemical components during wine-processing of Chuanxiong Rhizoma(CR), identify differential markers, and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis(PLS-DA), principal component analysis(PCA), discriminant factor analysis(DFA) and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models, and differential components were screened out based on variable importance in the projection(VIP) value1. Then, high performance liquid chromatography(HPLC) was employed to detect the content changes of four components(ferulic acid, senkyunolide I, senkyunolide A and ligustilide) during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L*(brightness value), a*(red-green value) and b*(yellow-blue value). Based on chromaticity differences, the color reference ranges were established for moderately processed CR, including L* of 46.75-48.24, a* of 5.37-6.07 and b* of 20.32-21.70. In odor analysis, DFA revealed significant differences among processing stages, and 11 odor markers were identified, with four differential markers(4-hydroxy-3-butylphthalide, isopropyl butyrate, L-limonene and 1-methoxyhexane) based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection, with discrimination accuracy rates of 92.4% and 93.272% for color and odor, respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages, and four differential components were screened out, providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

Objective:To analyze the iodine nutrition status of children and adolescents and influencing factors in Zhejiang Province, providing scientific basis for optimizing iodine deficiency disorders (IDD) prevention and control strategies.Methods:In June 2022, a multistage stratified sampling method was used to divide 16 counties (cities, districts, abbreviated as counties) in Zhejiang Province into three categories based on their geographical locations (average distance from the coastline): coastal areas (including Dinghai District, Jiaojiang District, Sanmen County, Cixi City and Lucheng District), sub-coastal areas (including Wuxing District, Haining City, Linping District, Fuyang District and Fenghua District), and inland areas(including Suichang County, Changshan County, Shengzhou City, Jindong District, Dongyang City and Yongjia County). One county was selected from each category, and one township (street) was selected from each county. Two administrative villages (neighborhood committees) were selected from each township (street). Ten households including all children and adolescents aged 6-17 in each household were selected from each administrative village (neighborhood committee). Demographic information and personal dietary characteristics were collected via questionnaires, while household salt and a random urine sample were tested for iodine level. Trend analysis was conducted using a χ 2trend test, and a multivariate logistic stepwise regression model was used to analyze the influencing factors of urinary iodine levels. Results:A total of 755 children and adolescents aged 6-17 were selected, including 387 males (51.26%) and 368 females (48.74%), with an age of (11.24 ± 3.32) years. There were 269 children and adolescents in coastal areas (35.63%) and 409 children and adolescents in urban areas (54.17%). A total of 755 household salt samples were collected, with a median salt iodine concentration of 21.80 mg/kg. These included 263 non-iodized salt samples, 38 unqualified iodized salt samples, and 454 qualified iodized salt samples. The coverage rate of iodized salt was 65.17% (492/755), and the consumption rate of qualified iodized salt was 60.13% (454/755). The distribution of salt iodine quality among children and adolescents in different geographical locations showed statistically significant differences (χ 2 = 111.95, P < 0.001), with the proportion of non-iodized salt gradually decreasing from coastal areas to inland areas (χ 2trend = 90.17, P < 0.001). A total of 755 urine samples were collected, with a median urinary iodine concentration of 186.60 μg/L. The proportions of urinary iodine < 100, 100-199, 200-299, and ≥300 μg/L were 16.95% (128/755), 37.62% (284/755), 24.37% (184/755), and 21.06% (159/755), respectively. The χ 2trend test revealed a nonlinear positive correlation between salt iodine level and urinary iodine level (χ 2regression = 21.98, P < 0.001; χ 2partial = 6.96, P < 0.001). The frequency distribution of urinary iodine in children and adolescents from different geographical locations and between urban and rural areas showed statistically significant differences (χ 2 = 29.63, 16.56, P < 0.001). Among them, the proportion of children and adolescents with urinary iodine < 100 μg/L gradually decreasing from coastal areas to inland areas (χ 2trend = 6.15, P = 0.013). The results of multivariate logistic regression analysis revealed that sub-coastal regions, inland regions, and urban-rural regions ( OR = 1.57, 1.53, 1.64, 95% CI: 1.11-2.24, 1.03-2.27, 1.17-2.32, P < 0.05) were significantly associated with urinary iodine levels in children and adolescents aged 6-17. Conclusions:In 2022, the iodine nutrition of children and adolescents in Zhejiang Province is generally suitable, but there is a risk of iodine deficiency among coastal children and adolescents. Geographic location and urban/rural areas are influencing factors on iodine nutrition status of children and adolescents in Zhejiang Province.

Objective:To analyze the factors influencing recurrence after liver transplantation in patients with primary biliary cholangitis (PBC).Methods:Clinical data of 53 patients with PBC undergoing liver transplantation at the Department of General Surgery, Beijing Youan Hospital, Capital Medical University from August 2006 to January 2024 were retrospectively anaylyzed, including 11 males and 42 females, aged (55.1±7.9) years. Eight (15.1%) of the patients experienced recurrence within five years after liver transplantation. Univariate and multivariate logistic regression analyses were used to identify the factors influencing recurrence after transplantation. The receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of each variable for post-transplant recurrence.Results:Univariate logistic regression analysis showed that severe postoperative complications, positive anti-centromere antibodies, and postoperative CD4/CD45<0.4 were associated with recurrence after liver transplantation (all P<0.05). Further multivariate logistic regression analysis revealed that severe postoperative complications ( OR=23.183, 95% CI: 1.667-322.447, P=0.019), postoperative CD4/CD45<0.4 ( OR=9.272, 95% CI: 1.244-69.099, P=0.030), and positive anti-centromere antibodies ( OR=17.106, 95% CI: 1.381-211.878, P=0.027) were associated with a higher risk of recurrence after liver transplantation in patients with PBC. ROC curve analysis showed that the area under the curve for predicting recurrence after liver transplantation based on severe postoperative complications was 0.731 (95% CI: 0.539-0.922, P=0.039), with a sensitivity of 75.0% and a specificity of 71.1%. Conclusion:Severe postoperative complications, CD4/CD45 <0.4, and positive anti-centromere antibodies are risk factors for recurrence after liver transplantation in patients with PBC. Severe postoperative complications showed a good predictive efficacy for recurrence.

Objective:To investigate the clinical effects and advantages of laparoscopic total mesorectal excision in the treatment of colorectal cancer.Methods:A total of 82 patients with colorectal cancer who received treatment at the Second Affiliated Hospital of Guizhou Medical University from January 2020 to January 2023 were selected for a prospective study. They were randomly assigned to two groups using a random number table, with 41 cases in each group. The control group underwent conventional laparotomy, while the observation group received laparoscopic total mesorectal excision. Clinical efficacy, clinical indicators, and immune function indicators were compared between the two groups.Results:The operation time for patients in the observation group was (1.98 ± 0.31) hours, the length of hospital stay was (8.32 ± 2.38) days, the recovery time for bowel function was (2.15 ± 0.34) days, and the intraoperative blood loss was (112.35 ± 12.66) mL, all of which were shorter and lower than those in the control group [(2.46 ± 0.32) hours, (14.52 ± 2.42) days, (3.25 ± 0.15) days, and (167.78 ± 12.35) mL, t = 6.90, 11.70, 18.95, 20.07, all P < 0.001). The short-term response rate in the observation group was higher than that in the control group ( χ2 = 4.10, P < 0.05). The immune function indicators in the observation group, including the CD4 +/CD8 + ratio (1.78 ± 0.54), immunoglobulin A [(3.87 ± 0.73) g/L], and immunoglobulin G [(11.83 ± 2.88) g/L], were all better than those in the control group [(1.36 ± 0.53), (1.78 ± 0.63) g/L, (6.37 ± 2.45) g/L, t = 3.55, 13.88, 9.25, all P < 0.001]. The incidence of complications in the observation group was 2.44% (1/41), which was significantly lower than that in the control group [19.51% (8/41), χ2 = 4.49, P < 0.05]. Conclusions:Laparoscopic total mesorectal excision for patients with colorectal cancer has significant advantages, including faster recovery, less bleeding, and fewer complications, making it more superior to conventional laparotomy.

Objective:To investigate the iodine nutrition status of pregnant women in Zhejiang Province, explore the impact of salt industry system reform on iodine nutrition level of pregnant women, and provide scientific basis for prevention and treatment of iodine deficiency disorders.Methods:From 2016 to 2021, a multi-stage stratified sampling method was used to select 100 pregnant women from 90 counties (cities, districts) in Zhejiang Province each year as survey subjects. Salt samples were collected from pregnant women's families, and one random urine sample was taken for salt iodine and urinary iodine level testing, respectively.Results:A total of 56 581 samples of household edible salt were collected from pregnant women, with a median salt iodine level of 23.20 mg/kg. Among them, 7 961 were non iodized salt, 45 803 were qualified iodized salt, and 2 817 were unqualified iodized salt. The iodized salt coverage rate was 85.93% (48 620/56 581), and the qualified iodized salt consumption rate was 80.95% (45 803/56 581). The proportion of non iodized salt increased from 10.05% (897/8 928) in 2016 to 15.09% (1 461/9 679) in 2021 (χ 2trend = 95.16, P < 0.001). A total of 56 581 urine samples were collected from pregnant women, with a median urinary iodine level of 130.50 μg/L. Among them, the proportions of urinary iodine levels < 150, 150 - 249, 250 - 499, and ≥500 μg/L were 58.32% (32 996/56 581), 27.24% (15 410/56 581), 12.24% (6 926/56 581), and 2.21% (1 249/56 581), respectively. The median urinary iodine level of pregnant women in inland areas was significantly higher than that in coastal areas ( Z = 19.15, P < 0.001). Furthermore, urinary iodine levels exhibited a non-linear decline as age increased (χ 2regression = 12.65, P < 0.001; χ 2partial = 22.65, P < 0.001) and as pregnancy progressed (χ 2regression = 37.28, P < 0.001; χ 2partial = 18.89, P < 0.001). Conclusions:The overall iodine nutrition status of pregnant women in Zhejiang Province is in a state of iodine deficiency (< 150 μg/L), and there is a greater risk in coastal areas compared to inland areas. However, in the context of the reform of the salt industry system, it is still necessary to strengthen the quality supervision of iodized salt, provide scientific iodine supplementation education, promote specialized iodized salt for pregnant women, and strengthen interventions for prevention and control of iodine deficiency disorders.

Objective:To investigate the differential responses of the endoplasmic reticulum stress-to-apoptosis cascade induced by proton ultra-high dose rate (FLASH) irradiation between lung epithelial and lung cancer cells.Methods:Human lung epithelial cells (KT) and lung adenocarcinoma cells (A549) were irradiated with protons, and divided into Ctrl, CONV and FLASH groups. Survival curves were generated using colony formation assay. Protein and mRNA expressions of the endoplasmic reticulum (ER) stress and apoptosis regulators were assessed via Western blot and RT-qPCR. The concentration of IL-6 secreted into the culture supernatant was determined by enzyme-linked immunosorbent assay(ELISA).Results:In KT cells, compared to the CONV group, FLASH irradiation resulted in a significantly higher survival fraction ( P<0.05), increased GRP78 protein expression ( t= 7.52, P < 0.05) and UPR-related genes PERK, ATF4, and CHOP. In A549, the cell survival rate did not differ significantly between the CONV and FLASH groups ( P > 0.05). UPR pathway was not activated in either group. However, both CONV and FLASH irradiation significantly promoted secretion of IL-6 ( t=4.31, 4.47, P<0.05), while no difference was identified between two groups. In KT, both irradiation promoted secretion of IL-6 ( t=7.43, 3.07, P<0.05) while IL-6 concentration in FLASH group was significantly lower than that in CONV group ( t=7.63, P<0.05). Additionally, a pro-apoptotic propensity in KT cells following FLASH irradiation and in A549 cells following both FLASH and CONV irradiation was identified. Conclusions:In KT cells, FLASH irradiation cleared misfolded proteins through activating UPR pathway, promoted apoptosis of damaged cells, suppressed IL-6 secretion to attenuate inflammatory injury, and ultimately enhanced cell survival. Furthermore, proton FLASH irradiation bypasses ER stress activation in A549 cells, instead directly priming an apoptotic disposition with concomitant IL-6 hypersecretion. This paracrine damage amplification cascade potentiates radiation-induced tumoricidal efficacy through sustained cytotoxic microenvironment remodeling.
