ObjectiveTo study the changing law of appearance color and physicochemical properties of Angelicae Sinensis Radix Carbonisata(ASRC) during the processing by color space method combined with statistical analysis, so as to provide reference for determining the processing endpoint and evaluating the quality of the decoction pieces. MethodsTaking processing time(4, 8, 12, 16 min) and temperature(180, 200, 220, 240 ℃) as factors, ASRC decoction pieces with different processing degrees were prepared in a completely randomized design. Then, the brightness value(L*), red-green value(a*), yellow-blue value(b*), and total chromaticity value (E*ab) of the decoction pieces were determined by spectrophotometer, the color difference value(ΔE) was calculated, and the data of colorimetric values were analyzed by discriminant analysis. At the same time, the pH, charcoal adsorption, and contents of tannins, 5-hydroxymethylfurfural(5-HMF), tryptophan, chlorogenic acid, ferulic acid, senkyunolide I, senkyunolide H and ligustilide of ASRC with different processing degrees were determined by pH meter, ultraviolet and visible spectrophotometry and ultra-high performance liquid chromatography(UPLC). Principal component analysis(PCA) was used to analyze the data of physicochemical indexes, after determining the processing technology of ASRC, the canonical discriminant function was established to distinguish the decoction pieces with different processing degrees, and leave-one-out cross validation was conducted. Finally, Pearson correlation analysis was used to explore the correlation between various physicochemical indexes and chromaticity values. ResultsWith the prolongation of the processing time, L*, a*, b* and E*ab all showed a decreasing trend, and the established discriminant model based on color parameters was able to distinguish ASRC with different processing degrees. The pH showed an increasing trend with the prolongation of processing time, and the charcoal adsorption, and the contents of tannins, 5-HMF, and tryptophan all showed an increasing and then decreasing trend. Among them, the charcoal adsorption, contents of tannin and 5-HMF reached their maximum values successively after processing for 8-12 min. While the contents of chlorogenic acid, ferulic acid, senkyunolide I, senkyunolide H and ligustilide decreased with the increase of processing time, with a decrease of 60%-80% at 8 min of processing. Therefore, the optimal processing time should be determined to be 8-12 min. PCA could clearly distinguish ASRC with different processing degrees, while temperature had no significant effect on the processing degree. The 12 batches of process validation results(10 min, 180-240 ℃) showed that except for 3 batches identified as class Ⅱ light charcoal, all other batches were identified as class Ⅲ standard charcoal, and the chromaticity values of each batch of ASRC were within the reference range of class Ⅱ-Ⅲ sample chromaticity values. The correlation analysis showed that the chromaticity values were negatively correlated with pH and charcoal adsorption, and positively correlated with contents of tryptophan, chlorogenic acid, ferulic acid, senkyunolide I, senkyunolide H, and ligustilide. And both pH and charcoal adsorption were negatively correlated with the contents of the above components, but the charcoal adsorption was positively correlated with the content of 5-HMF. ConclusionThe chromaticity values and the contents of various physicochemical indicators of ASRC undergo significant changes with the prolongation of processing time, and there is a general correlation between chromaticity values and various physicochemical indicators. Based on the changes in color and physicochemical indicators, the optimal processing time for ASRC is determined to be 8-12 min. This study reveals the dynamic changes of the relevant indexes in the processing of ASRC, which can provide a reference for the discrimination of the processing degree and the quantitative study of the processing endpoint.

Objective To explore the role of neogambogic acid in the characteristics of colorectal cancer stem cells (CRC-CSCs) through the Wnt/β-catenin signaling pathway. Methods The colorectal cells SW480 and HCT166 were divided into control group and neogambogic acid groups (1.5, 3, 6, and 12 μmol/L). The viability of CRC-CSCs was determined by MTT method, and spheroid and clone formation assays were used to assess the capacity of spheroid formation and self-renewal ability of the cells. The effects of neogambogic acid on the apoptosis and cell cycle of CRC-CSCs were evaluated by flow cytometry assays. Real-time quantitative PCR was used to detect the mRNA expression levels of relative markers (CD133, CD44, ALDH1, Oct4, and Nanog) of CRC-CSCs, and the protein expression levels of the self-renewal marker (PCNA), apoptosis markers (cleaved caspase-3 and cleaved caspase-9), and Wnt/β-catenin signaling pathway markers (p-GSK3β, GSK3β, β-catenin, and Wnt) were analyzed using Western blot. Results Compared with the control group, after neogambogic acid treatment, the viability of SW480 and HCT116 cells decreased (P<0.05), the spheroid forming ability and the clone numbers of CRC-CSCs decreased (P<0.001, P<0.01) but the cell apoptosis rate increased (P<0.01), and cell cycle was arrested in G0/G1 phase. Moreover, neogambogic acid downregulated the mRNA and protein expression of relative markers of CRC-CSCs (CD133, CD44, ALDH1, Oct4, and Nanog), PCNA, p-GSK3β, β-catenin, and Wnt (P<0.05) and upregulated the expression of cleaved caspase-3, cleaved caspase-9, and GSK3β (P<0.01). Conclusion Neogambogic can inhibit the stem cell properties of colorectal cells via inhibition of Wnt/β-catenin signaling pathway. As a result, neogambogic acid may be an attractive agent against colorectal cancer.

Objective:
To investigate the impact of preschool children s aquatic motor skill (AMS) acquisition on their fundamental motor skill (FMS) development and the correlation between AMS and FMS development, so ao to provide a scientific basis for early childhood education and physical education teaching.
Methods:
From April to June 2024, 60 children, recruited by random sampling from a kindergarten in Taiyuan, were stratified randomly divided into an experimental group ( n =30) and a control group ( n =30). The experimental group were further divided into five classes of six each. They received AMS practice interventions twice weekly, 40 minutes per session, over eight weeks (16 sessions total) at a designated swimming center. The control group maintained their usual routine. Children s FMS and AMS were assessed pre and post intervention using the Test of Gross Motor Development-3rd (TGMD3) and Actual Aquatic Skills Test (AAST), respectively. Before and after test comparisons within and between groups employed t-tests, Wilcoxon signedrank tests, ANCOVA (including ranktransformed ANCOVA), and Cohen s d effect sizes were calculated for standardized mean differences. Spearman rank correlation was used to analyze relationships between FMS and AMS.
Results:
After the aquatic learning, the experimental group scored significantly higher than the control group on locomotor skills ( F=20.47, P <0.01, η 2=0.26), FMS ( F=4.59, P =0.04, η 2=0.08), and AMS ( F=109.71, P<0.01, η 2=0.79). The experimental groups improvement in locomotor skills 5.0(3.8, 7.3) versus the control group (2.8±2.5) yielded a medium effect size (Cohen s d =0.71); AMS gains in the experimental group [26.0(20.8, 28.0)] versus controls [1.0(0, 2.3)] showed a very large effect size (Cohen s d =4.73) (both P <0.01). Among preschool children, AMS acquisition was positively correlated with locomotor skills ( r =0.39) and overall FMS ( r =0.43)(both P <0.05). Skill specific assessments revealed lower proficiency in headfirst entry (immersion), treading water, and sagittalplane rotation.
Conclusion
Preschool children s acquisition of AMS has a positive effect on their FMS, with mutual facilitation between the two, especially in locomotor abilities.

ObjectiveTo observe the clinical effectiveness and potential mechanism of combined tongue three-needle acupuncture and acupoint application on Lianquan (CV 23) for patients with dysphagia after ischemic stroke. MethodsA prospective study was conducted on 160 patients with post-stroke dysphagia, who were randomly divided into a treatment group and a control group, with 80 cases in each group. The control group received conventional rehabilitation training, while the treatment group received tongue three-needle acupuncture combined with acupoint application on Lianquan (CV 23) on the basis of conventional rehabilitation training, for 4 weeks in both groups. We compared the clinical effectivenss of both groups after treatment, and assessed the swallowing function including videofluoroscopic swallowing study (VFSS), standardized swallowing assessment (SSA) and functional oral intake scale (FIOS), swallowing contrast test including hyoid maximum displacement (HmaxD), pharyngeal transit time (PTT), and upper esophageal sphincter (UES) opening, surface electromyography (sEMG) test including maximum amplitude and swallowing duration as well as swallowing quality of life questionnaire (SWAL-QOL) score of the patients in both groups before treatment, after 2 weeks and 4 weeks of treatment, respectively. ResultsThe total effective rate in treatment group was 82.50% (66/80), significantly higher than 66.25% (53/80) in control group (P<0.05). The VFSS, and FOIS scores, UES opening rate and HmaxD, sEMG maximal amplitude values, and SWAL-QOL scores were increased in both groups after 2 weeks and 4 weeks of treatment compared with the values before treatment (P<0.05), while SSA scores, PTT, and swallowing duration were decreased compared within group before treatment (P<0.05). VFSS and FOIS scores, UES opening rate and HmaxD, sEMG maximal amplitude values, and SWAL-QOL scores after 2 and 4 weeks of treatment in the treatment group were higher (P<0.05), while SSA scores, PTT, and swallowing duration were lower (P<0.05) than those in the control group at the same time. ConclusionCombined tongue three-needle acupuncture and acupoint application on Lianquan (CV 23) for patients with dysphagia after ischemic stroke can significantly improve swallowing activities, and its mechanism of action may be related to the improvement of the contraction ability and coordination of swallowing-related muscle groups.

Objective To explore the clinical value of artificial intelligence (AI) quantitative parameters in distinguishing pathological grades of stageⅠ invasive adenocarcinoma (IAC). Methods Clinical data of patients with clinical stageⅠ IAC admitted to Yantaishan Hospital Affiliated to Binzhou Medical University from October 2018 to May 2023 were retrospectively analyzed. Based on the 2021 WHO pathological grading criteria for lung adenocarcinoma, IAC was divided into gradeⅠ, grade Ⅱ, and grade Ⅲ. The differences in parameters among the groups were compared, and logistic regression analysis was used to evaluate the predictive efficacy of AI quantitative parameters for grade Ⅲ IAC patients. Parameters were screened using least absolute shrinkage and selection operator (LASSO) regression analysis. Three machine learning models were constructed based on these parameters to predict grade Ⅲ IAC and were internally validated to assess their efficacy. Nomograms were used for visualization. Results A total of 261 IAC patients were included, including 101 males and 160 females, with an average age of 27-88 (61.96±9.17) years. Six patients had dual primary lesions, and different lesions from the same patient were analyzed as independent samples. There were 48 patients of gradeⅠ IAC, 89 patients of grade Ⅱ IAC, and 130 patients of grade Ⅲ IAC. There were statitical differences in the AI quantitive parameters such as consolidation/tumor ratio (CTR), ect among the three goups. (P<0.05). Univariate analysis showed that the differences in all variables except age were statistically significant (P<0.05) between the group gradeⅠ+grade Ⅱand the group grade Ⅲ . Multivariate analysis suggested that CTR and CT standard deviation were independent risk factors for identifying grade Ⅲ IAC, and the two were negatively correlated. Grade Ⅲ IAC exhibited advanced TNM staging, more pathological high-risk factors, higher lymph node metastasis rate, and higher proportion of advanced structure. CTR was positively correlated with the proportion of advanced structures in all patients. This correlation was also observed in grade Ⅲ but not in gradeⅠand grade ⅡIAC. CTR and CT median value were selected by using LASSO regression. Logistic regression, random forest, and XGBoost models were constructed and validated, among which, the XGBoost model demonstrated the best predictive performance. Conclusion Cautious consideration should be given to grade Ⅲ IAC when CTR is higher than 39.48% and CT standard deviation is less than 122.75 HU. The XGBoost model based on combined CTR and CT median value has good predictive efficacy for grade Ⅲ IAC, aiding clinicians in making personalized clinical decisions.

AIM: To explore the clinical application effect of visual training equipment combined with conventional corrective treatment on children with ametropic amblyopia(AMA).METHODS: Prospective randomized control study. A total of 188 children(376 eyes)with AMA treated in our hospital from June 2021 to December 2022 were selected, and they were divided into two groups using a random number table. The conventional correction group(94 cases, 188 eyes)received conventional correction treatment, while the visual training group(94 cases, 188 eyes)received visual training equipment combined with conventional correction treatment, both lasted for 12 mo. The best corrected visual acuity, diopter, eye accommodation function, adverse reactions, amblyopia recurrence rates, and clinical efficacy were compared between the two groups at 6 and 12 mo after treatment.RESULTS:The two groups each had 8 cases(16 eyes)detached, the rate of loss to follow-up was 8.5%, and 86 cases(172 eyes)were included in each group. There were statistically significant differences in the best corrected visual acuity, diopter, amplitude of accommodation, accommodation facility and accommodative lag between the two groups of children before and after treatment(all P<0.05). The total effective rate of the visual training group(98.8%)was higher than that of the conventional correction group(91.9%; P<0.05). There was no statistically significant difference in the total effective rate of clinical efficacy between the two groups in different age groups and different degrees of amblyopia(all P>0.05). There was no statistically significant difference in the incidence of redness and swelling between the two groups(P>0.05). The recurrence rate of amblyopia in the visual training group(1.2%)was lower than that in the conventional correction group(8.1%; P<0.05).CONCLUSION: The combination of visual training equipment and conventional correction therapy has a significant clinical effect on children with AMA, which can effectively correct visual acuity, adjusting diopter and improve eye accommodation function, and recurrence rate of amblyopia is low and safety is high.

With the wide application of phacoemulsification and intraocular lens implantation, many cataract patients have effectively recovered vision. Postoperative intraocular lens opacification is an important indicator for evaluating biocompatibility, as it affects the visual quality of patients. The manifestation and risk factors of opacification vary among different materials used for intraocular lenses. However, better visual quality after surgery is not determined by a single factor. The material of the intraocular lens and the patient's response to the intraocular lens are all factors that affect the postoperative visual quality. With the continuous advancement of technology, an increasing number of new materials are being applied in the field of intraocular lenses. Fully understanding the characteristics of intraocular lens materials, selecting suitable intraocular lens for patients and reducing complications caused by materials will be beneficial to patients. The characteristics of different intraocular lens materials and the risk factors of opacification after intraocular lens implantation were discussed in this paper.

【Objective】 To discuss the effect of adding tranexamic acid(TXA) during surgery on blood loss and security during short segment lumbar spinal stenosis surgery. 【Methods】 One hundred and eight patients with lumbar spinal stenosis who were to undergo lumbar posterior fusion surgery were randomly divided into control group, TXA group and adding TXA group, with 36 patients in each group. In the control group, TXA was not used during surgery.The TXA group received intravenous infusion of 100 mL normal saline mixture containing 1 g of TXA 15 minutes before surgery after anesthesia. In adding TXA group, after the same operation in TXA group, 10 mg/kg(body weight) of TXA was infused 3 hours later. Total perioperative blood loss, dominant blood loss, hidden blood loss, intraoperative blood loss, postoperative drainage volume, and transfusion rate were recorded in the two groups. Hemoglobin (Hb), hematocrit(HCT), prothrombin time international standardized ratio (PT-INR), prothrombin time(PT), activated partial thromboplastin time(APTT), blood platelet count (BPC), D-dimer (D-D), fibringen(FIB), C-reactive protein (CRP), alanine aminotransferase (ALT), blood urea nitrogen (BUN) were measured 3 days before and after the surgery in the three groups. Postoperative adverse events were followed up. 【Results】 The total blood loss(mL) [(968.7±209.6) vs (1 369.8±276.3), (968.7±209.6) vs (1 273.9±250.2)], dominant blood loss(mL) [(590.5±164.3) vs (876.4±235.9), (590.5±164.3) vs (789.3±221.7)], intraoperative blood loss(mL) [(318.7±120.7) vs (457.8±146.6), (318.7±120.7) vs (423.9±162.3)] and postoperative drainage volume(mL) [1 day after surgery: (164.6±25.0) vs (262.3±51.7), (164.6±25.0) vs (219.8±37.1); 3 days after surgery: (107.2±18.6) vs (156.3±37.6), (107.2±18.6) vs (145.3±22.3)] of the adding TXA group were lower than those of the control group and TXA group (P<0.05), and the transfusion rate was lower than that of the control group (P<0.05).The postoperative drainage volume and transfusion rate of TXA group were lower than that of the control group (P<0.05).There was no statistical difference in the amount of hidden blood loss between the three groups (P>0.05). Compared with the preoperative results, Hb, Hct and BPC in the three groups decreased (P<0.05), and D-D, FIB and CRP increased (P<0.05), but the change degree of Hb, Hct, BPC, D-D and CRP in the TXA group and the adding TXA group was less than that in the control group (P<0.05), and the change degree of Hb, Hct, BPC, D-D and CRP in the adding TXA group was less than that in the TXA group (P<0.05).There was no statistically significant difference in PT-INR, PT, APTT, ALT and BUN between and within the three groups before and after surgery (P>0.05), and all of them were within the normal range. No serious adverse events such as deep vein thrombosis, pulmonary embolism, epilepsy, liver and kidney damage were found in all patients after postoperative follow-up. 【Conclusion】 Intraoperative addition of TXA can effectively reduce the amount of blood lost during short segment lumbar spinal stenosis surgery without increasing the risk of complications such as coagulation disorders, thrombosis, liver and kidney function damage.

Chronic atrophic gastritis is a common and frequent disease in clinical practice. The symptoms of this disease can be attributed to the categories of " gastric pain" and " plumpness" in traditional Chinese medicine,and its pathogenesis is closely related to the dysfunction of xuanfu,qi-fluids,and stomach collaterals. In this study,we systematically rationalize the historical origin of the xuanfu,qi-fluids,and stomach collaterals and the relationship between them. According to the structure,physiological function and pathological characteristics of " xuanfu-qi-fluids-stomach collaterals",combined with the evolution of the chronic atrophic gastritis disease process,xuanfu depression and closure is believed to be the direct cause of chronic atrophic gastritis occurrence. The disharmony between qi and fluids is the core of the progression of chronic atrophic gastritis. Collateral deficiency and toxin damage are the root causes of the progression of chronic atrophic gastritis. Based on the mechanism of "xuanfu depression and closure-the disharmony between qi and fluids-collateral deficiency and toxin damage",it is proposed to open the xuanfu,restore the pivotal mechanism,activate blood circulation and diuresis,propagate qi and fluids,and supplement deficiency to unblock collaterals. From the perspective of "xuanfu-qi-fluids-stomach collaterals ",a more systematic and comprehensive understanding of the dynamic development process of chronic atrophic gastritis can be achieved,which will provide new ideas for the treatment of this disease in traditional Chinese medicine.

OBJECTIVE:
To identify phytochemical constituents present in the extract of flowers of Xanthoceras sorbifolia and evaluate their anti-oxidant and anti-hyperglycemic capacities.
METHODS:
The AlCl3 colorimetric method and Prussian Blue assay were used to determine the contents of total flavonoids and total phenolic acids in extraction layers, and the bioactive layers was screened through anti - oxidative activity in vitro. The Waters ACQUITY UPLC system and a Waters ACQUITY UPLC BEH C18 column (2.0 mm × 150 mm, 5 μm) were used to identify the ingredients. And anti-oxidative ingredients were screened by off-line UPLC-QTOF-MS/MS-free radical scavenging. The ameliorative role of it was further evaluated in a high-fat, streptozotocin-induced type 2 diabetic rat model and the study was carried out on NADPH oxidase (PDB ID: 2CDU) by molecular docking.
RESULTS:
Combined with the results of activity screening in vitro, the anti - oxidative part was identified as the ethyl acetate layer. A total of 24 chemical constituents were identified by liquid chromatography-mass spectrometry in the ethyl acetate layer and 13 main anti-oxidative active constituents were preliminarily screened out through off-line UPLC-QTOF-MS/MS-free radical scavenging. In vivo experiments showed that flowers of X. sorbifolia could significantly reduce the blood glucose level of diabetic mice and alleviate liver cell damage. Based on the results of docking analysis related to the identified phytocompounds and oxidase which involved in type 2 diabetes, quercetin 3-O-rutinoside, kaempferol-3-O-rhamnoside, isorhamnetin-3-O-glucoside, and isoquercitrin showed a better inhibitory profile.
CONCLUSION
The ethyl acetate layer was rich in flavonoids and phenolic acids and had significant anti-oxidant activity, which could prevent hyperglycemia. This observed activity profile suggested X. sorbifolia flowers as a promising new source of tea to develop alternative natural anti-diabetic products with a high safety margin.
