ObjectiveTo explore the mechanism of modified Xiehuangsan in treating tic disorders （TD） based on microglial polarization and the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor （NF）-κB pathway. MethodsSeventy-two Sprague-Dawley （SD） rats were randomly assigned into six groups： control， model， tiapride （0.025 g·kg^-1）， and low-， medium-， and high-dose （12， 24， 48 g·kg^-1， respectively） modified Xiehuangsan， with 12 rats in each group. Except the control group， the other groups received intraperitoneal injection of 3，3'-iminodipropionitrile （IDPN） for 7 consecutive days for the modeling of TD. After successful modeling， the control and model groups were given normal saline via gavage， and the other groups were administrated with corresponding drugs by gavage. After 28 days of continuous intervention， rat behaviors were observed， and the modified Xiehuangsan group showing the best anti-TD effect was selected for deciphering the treatment mechanism. Hematoxylin and eosin staining was conducted to observe morphological changes in the rat striatum. Immunohistochemistry was employed to detect the expression of CD16 and CD206 in the striatum. Real-time PCR was employed to measure the mRNA levels of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， IL-4， TLR4， MyD88， and NF-κB p65 in the striatum. Western blot was employed to determine the protein levels of ionized calcium-binding adapter molecule 1 （Iba1）， Fc receptor family for immunoglobulin （Ig）G type Ⅲ （CD16）， mannose receptor （CD206）， TLR4， MyD88， and NF-κB p65 in the striatum. ResultsCompared with the control group， the model group showed increased stereotyped behaviors， locomotor activity， total movement distance， and movement speed， shortened resting time （P<0.01）， and noticeable pathological changes in the striatum. Compared with the model group， the tiapride group and modified Xiehuangsan groups exhibited reduced stereotyped behavior， locomotor activity， total movement distance， and movement speed， prolonged resting time （P<0.05， P<0.01）， and alleviated pathological changes in the striatum. Among the modified Xiehuangsan groups， the high-dose group had the best intervention effect and the mildest pathological changes. Therefore， the high-dose group was selected for further research. Compared with the control group， the modeling of TD increased Iba1 and CD16 expression （P<0.05， P<0.01）， up-regulated the mRNA levels of IL-1β and TNF-α （P<0.05， P<0.01）， down-regulated the mRNA level of IL-4 （P<0.05）， up-regulated the mRNA and protein levels of TLR4 and MyD88 （P<0.05， P<0.01）， and up-regulated the protein level of NF-κB p65 （P<0.01）. Compared with the model group， modified Xiehuangsan reduced Iba1 and CD16 expression （P<0.05， P<0.01）， up-regulated the protein level of CD206 （P<0.05， P<0.01）， down-regulated the mRNA levels of IL-1β and TNF-α （P<0.05）， up-regulated the mRNA level of IL-4 （P<0.01）， and down-regulated the mRNA and protein levels of TLR4， MyD88， and NF-κB p65 （P<0.05， P<0.01）. ConclusionModified Xiehuangsan demonstrated a definite therapeutic effect on TD in rats. It may reduce neuroinflammation in TD rats by regulating the polarization of microglia in the striatum via the TLR4/MyD88/NF-κB signaling pathway.

OBJECTIVE To observe the effects of Modified shaoyao gancao decoction on intestinal transit function， intestinal flora and the contents of metabolites [γ aminobutyric acid （GABA） and 5-hydroxytryptamine （5-HT）] in slow transit constipation （STC） rats. METHODS SD rats were randomly divided into blank group （10 rats） and modeling group （30 rats）， with half male and half female. The STC model was established by intragastric administration of Compound diphenoxylate tablets in the modeling group. The successfully modeled rats were randomly divided into model group， Modified shaoyao gancao decoction group [56 g/（kg·d）， calculated by crude drug] and positive control group [lactulose 2.09 g/（kg·d）]， with 10 rats in each group. Each administration group was given relevant medicine intragastrically， the blank group and model group received an equivalent volume of normal saline， once a day， for 14 consecutive days. During the experiment， the general situation of rats was observed in each group. After the last medication， the body weight was measured， and the Bristol score was used to evaluate the fecal characteristics. The fecal moisture content， intestinal propulsion rate， and the contents of GABA and 5-HT in intestinal content were detected； the diversity of intestinal flora in intestinal contents was investigated， and the correlation between the contents of GABA， 5-HT and relative abundance of microbiota was analyzed. RESULTS Compared with the model group， general conditions such as small body shape， sparse and rough fur， and slow movement were all improved in Modified shaoyao gancao decoction body weight， Bristol score， fecal moisture content，intestinal propulsion rate， 5-HT content， Chao1 index and Shannon index were increased significantly， while GABA content and Simpson index were decreased significantly （P＜0.05）. The intestinal flora of rats in the Modified shaoyao gancao decoction group could be classified as the same as the blank group， but was far from the model group； the relative abundances of Desulfobacterota， Firmicutes and Bacteroidota in this group showed a tendency of pull back， but the differences were not statistically significant compared to model group （P＞0.05）. Desulfobacterota was an intergroup differential factor （P＜0.05）. The content of GABA was negatively correlated with the relative abundance of Bacteroidota， Cyanobacteria， Patescibacteria and Actinobacteriota （P＜0.05）. The content of 5-HT was positively correlated with the relative abundance of Campilobacterota （P＜0.05）. CONCLUSIONS Modified shaoyao gancao decoction can improve the fecal properties and intestinal motility of STC rats. Its mechanism may be related to improving intestinal flora and then affecting the contents of GABA and 5-HT in intestinal contents. In addition， the contents of GABA and 5-HT may be significantly correlated with the relative abundance of specific bacterial phyla such as Bacteroidota and Campilobacterota.

OBJECTIVE To explore the mechanism of Shaoyao gancao decoction in improving intestinal motility in rats with slow transit constipation （STC） by regulating acid-sensitive ion channel 3 （ASIC3）/extracellular signal-regulated kinase （ERK） signaling pathway. METHODS SD rats were used to construct an STC model by gavage with compound diphenoxylate. The successfully modeled rats were randomly divided into model group， Shaoyao gancao decoction group （1.5 g/mL）， lactulose group （208.4 mg/mL， positive control）， and combined inhibition group （Shaoyao gancao decoction 1.5 g/mL+amiloride hydrochloride 20 μg/kg）， with 12 rats in each group. Additionally， 12 healthy rats were selected as the blank group. They were given relevant medicine once a day and continuously intervened for 14 days. After intervention， the intestinal propulsion function and visceral sensitivity of the model rats were detected. The expression of ASIC3 in the colon tissue of rats was observed by immunohistochemical staining. mRNA expressions of ASIC3， ERK1 and ERK2 as well as protein expressions of ASIC3， ERK1/2 and phosphorylated ERK1/2 （p-ERK1/2） in colon tissue of rats were detected； the ultrastructural changes of the enteric nervous system （ENS） -interstitial cell of Cajal （ICC）-smooth muscle cell （SMC） network in the rat colon were observed under electron microscopy. RESULTS Compared with the model group， the intestinal propulsion rate of the Shaoyao gancao decoction group was significantly increased， while the visceral pain threshold was significantly decreased. The proportion of the positive area of ASIC3 in the colonic tissue was significantly increased. The relative mRNA expression levels of ERK1， ERK2， and ASIC3， as well as the relative protein expression levels of p-ERK1/2 and ASIC3， and the p-ERK1/2 to ERK1/2 in the colonic tissue， were all significantly increased （P＜0.05 or P＜0.01）. Additionally， there was marked repair of the morphological structure of ICC and SMC， with closer gap junctions observed. Compared with the Shaoyao gancao decoction group， the combined inhibition group exhibited a diminished improvement in intestinal motility of rats， with statistically significant differences in the levels of some indicators （P＜0.05 or P＜0.01）； the repairing of the morphological structure of ICC and SMC was notably attenuated. CONCLUSIONS Shaoyao gancao decoction can effectively improve the intestinal transmission function and promote intestinal repair in STC rats， and its mechanism may be related to regulating the balance of the ENS-ICC-SMC network mediated by the ASIC3/ERK signaling pathway， thus promoting intestinal motility and reducing visceral sensitivity.

OBJECTIVE To establish a content determination method for multiple components in Sophora flavescens from different origins and to evaluate its quality by combining with chemometrics. METHODS Thirteen batches （No. K1-K13） of S. flavescens from different origins were selected as test samples. A high-performance liquid chromatography-tandem triple quadrupole mass spectrometry （HPLC-MS/MS） method was established to determine the contents of 12 components， including matrine， oxymatrine， betaine， cytisine， N-methylcytisine， sophoridine， genistein， sophoricoside， sophorone， formononetin， sophorolone Ⅰ and norkurarinone in S. flavescens. Chromatographic separation was performed on a Shim-pack GIST-HP C18 column with a mobile phase consisting of methanol （A） and water containing 0.1% formic acid （B）， using gradient elution at a flow rate of 0.25 mL/min， column temperature of 35 ℃， and an injection volume of 3 μL. Mass spectrometry was conducted using an electrospray ionization source with positive and negative ion scanning. Data were collected in segments using the multiple reaction monitoring mode. Technique for order preference by similarity to ideal solution （TOPSIS） and grey relational analysis （GRA）methods were employed to compare and comprehensively evaluate the 13 batches of S. flavescens from different origins. RESULTS The methodological validation for the content determination met the relevant regulatory requirements. The contents of the 12 components were 490.66-1 231.00， 11 088.10- 18 021.50， 7.91-25.38， 903.97-1 713.64， 336.08-1 485.54，1 065.33-2 075.50， 27.52-71.80， 109.36-517.83， 6 034.55-10 632.73， 21.26-145.35， 814.84-1 911.32， 1 040.87-3 446.37 μg/g）， respectively. TOPSIS results showed that the top 7 samples in Euclidean distance ranking were K6， K12， K11， K3， K5， K10， K13. The GRA results showed that the top 7 samples in the relative correlation ranking were K12， K11， K10， K6， K13， K5， K3. CONCLUSIONS The established HPLC-MS/MS method is rapid， accurate， highly sensitive， stable and reliable. Combined with chemometrics methods， it can be used for the quality control and evaluation of S. flavescens. The comprehensive quality of samples K3， K5， K6（ from Hebei）， K10（ from Sichuan）， K11-K13（ from Shanxi）， etc. is relatively superior.

Objective To investigate the role of pulmonary neuroendocrine cells(PNEC)and γ-aminobutyric acid(GABA)in patients with pulmonary neuroendocrine tumors(PNET).Methods The pathological specimens of 29 cases of PNET treated in the eighth Medical Center of Chinese PLA General Hospital from October 2018 to January 2022 were collected.The morphological characteristics were observed by HE staining,and the expression levels of synaptophysin(Syn),chromogranin A(CgA),CD56,Ki-67,CD86 and CD163 were observed by immunohistochemical staining.Calcitonin gene-related peptide(CGRP)and glutamic acid decarboxylase(GAD)65/67 in different types of PNETs were detected by double antibody immunofluorescence co-staining,and the correlation between GAD65/67 positive PNEC and macrophage polarization was analyzed.Results The results of HE staining showed that all four types of PNET tissues had neuroendocrine(NE)characteristics:rosette structure and organ nesting or palisade pattern,but they were different,and the proportion of mitotic cells from low to high was typical carcinoid(TC),atypical carcinoid(AC),large cell neuroendocrine carcinoma(LCNEC)and small cell lung cancer(SCLC).The results of immunohistochemical staining showed that the positive expression rate of Syn and CgA and the positive degree of Syn,CgA and CD56 in carcinoid(TC and AC)were significantly higher than those in LCNEC and SCLC(P＜0.05).The Ki-67 indices of the four types of PNET are:TC＜5%,AC 5%-20%,LCNEC and SCLC＞75%respectively.The number of PNEC in carcinoid was significantly higher than that in LCNEC,SCLC and paratumoral tissues(P＜0.05),but there was no significant difference in the number of PNEC between LCNEC and SCLC and para-tumor tissues(P＞0.05).The results of immunofluorescence staining showed that the number of GAD65/67 positive cells co-expressing GAD65/67 in 95%PNEC was significantly higher than that in LCNEC,SCLC and para-tumor tissues(P＜0.05),but there was no significant difference between LCNEC and SCLC GAD65/67 positive cells and para-tumor tissues(P＞0.05).The results of immunohistochemical staining also showed that the number of CD86 positive M1 macrophages was significantly higher than that of CD163 positive M2 macrophages in para-tumor tissues(P＜0.05),while M2 macrophages were significantly more than M1 macrophages in AC,LCNEC and SCLC(P＜0.01).Correlation analysis showed that the number of GAD65/67 positive PNEC cells in PNET was negatively correlated with the number of CD163 positive M2 macrophages in tumor stroma(r=-0.6336,P=0.0174).Conclusions PNEC is the main source of GABA in lung tissue and plays an immunomodulatory role in the lung,which may be involved in the progression of PNET.

Objective:To understand the potential categories of e-health literacy of elderly diabetic patients in community, and analyze the relationship between each category and physical activity level, in order to provide theoretical basis for formulating intervention measures to improve e-health literacy of elderly diabetic patients.Methods:This study was across-sectional survey. Elderly diabetic patients from 3 community health service centers in Fenyang City, Shanxi Province were selected by convenient sampling method from January to June 2023. General data questionnaire, e-Health Literacy Scale and International Physical Activity Questionnaire were used to investigate the elderly diabetic patients. Mplus8.0 was used for potential profile analysis, and SPSS 26.0 software was used to compare the differences in physical activity levels among different categories of e-health literacy.Results:Totally 248 elderly diabetes patients in the community aged 60-88 (63.8 ± 6.4) years, 135 males (54.4%) and 113 females (45.6%). The e-health literacy scores of 248 elderly diabetic patients in community were (17.70 ± 5.30), which could be divided into three potential categories: general low literacy group (56.0%, 139/248), high evaluation ability-medium literacy group (18.2%, 45/248) and high access ability-high literacy group (25.8%, 64/248). Three potential categories of physical activity levels were (1 464.74 ± 190.37), (2 094.40 ± 139.70), (2 368.44 ± 157.27) metabolic equivalent-min per week, and the difference was statistically significant ( F=118.83, P<0.001). Conclusions:The e-health literacy of elderly diabetic patients in community can be divided into three potential categories, and the physical activity level of patients with different e-health literacy categories is different. It is suggested that targeted intervention should be conducted based on the homogenous group of elderly diabetic patients with e-health literacy to improve their physical activity level.

ObjectiveTo investigate the mechanism of Xuefu Zhuyu capsules against atherosclerosis via regulating polarization of macrophages based on Notch1/jagged canonical Notch ligand 1（Jagged1）/Hes family BHLH transcription factor 1（Hes1） signaling pathway. MethodThe mouse models with atherosclerosis were prepared by feeding the mice with an ApoE^-/- high-fat diet for four weeks， and they were randomly divided into the model group， Xuefu Zhuyu capsule group， and atorvastatin group. C57BL/6 mice were fed as a normal group. The Xuefu Zhuyu capsule group was intragastrically given Xuefu Zhuyu capsules （0.728 g·kg^-1·d^-1）， and the atorvastatin group was intragastrically given atorvastatin tablet （6.07 mg·kg^-1·d^-1）. The normal group and the model group were given equal volume of the deionized water by intragastric administration， and the intervention lasted for 12 weeks. Aortic plaque morphology was observed by hematoxylin-eosin （HE） staining， and aortic plaque area and lipid deposition were observed by oil red O staining. The positive expression levels of CD86 and CD206 in aortic tissue were detected by immunohistochemistry， and serum levels of tumor necrosis factor （TNF）-α， interleukin（IL）-1β， transforming growth factor （TGF）-β₁， and IL-10 were detected by enzyme-linked immunosorbent assay （ELISA）. The relative mRNA expressions of inducible nitric oxide synthase （iNOS）， arginase-1 （Arg-1）， Notch1， Jagged1， and Hes1 in aortic tissue were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The relative protein expression of iNOS， Arg-1， Notch1， Jagged1， and Hes1 in aortic tissue was detected by Western blot. ResultCompared with the normal group， the model group had significant aortic plaque and lipid deposition， and the expression levels of pro-inflammatory cytokines TNF-α and IL-1β were increased （P<0.01）. The expression level of anti-inflammatory cytokine TGF-β₁ showed a downward trend， but the difference was not statistically significant. The mRNA and protein expressions of iNOS were increased （P<0.01）. The protein expression of Arg-1 was decreased （P<0.01）， and the mRNA expression of related pathway molecule Jagged1， as well as the protein expressions of Notch1， Jagged1， and Hes1 were increased in the model group （P<0.05， P<0.01）. Compared with those in the model group， the plaque area and lipid deposition had a decreasing trend in the Xuefu Zhuyu capsule group， and the expressions of TNF-α and IL-1β showed a downward trend. The expression of TGF-β₁ was increased （P<0.05）， and the expression of macrophage marker CD86 was decreased. The mRNA and protein expressions of iNOS were decreased （P<0.01）. The mRNA and protein expressions of Arg-1 were increased （P<0.05， P<0.01）. Furthermore， the mRNA and protein expressions of Notch1， Jagged1， and Hes1 were decreased （P<0.01）. ConclusionXuefu Zhuyu capsules can reduce aortic plaque area and lipid deposition in mice with atherosclerosis， alleviate inflammation， inhibit M1 macrophages， and promote the expression of M2 macrophages， and the mechanism may be related to the regulation of Notch1/Jagged1/Hes1 signaling pathway.

ObjectiveTo investigate the clinical efficacy of Gandouling tablet （GDL） on abnormal lipid metabolism in Wilson's disease （WD） and the correlation between the prediction model of hepatic steatosis and the related indexes of lipid metabolism in WD. MethodA total of 86 patients with abnormal lipid metabolism in WD were selected. The 24-hour urine copper， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， serum triglyceride （TG）， total cholesterol （TC）， apolipoprotein B （ApoB）， low density lipoprotein cholesterol （LDL-C）， bile acid （BA）， γ-glutamyl transferase （GGT）， prediction model of hepatic steatosis ［hepatic steatosis index （HSI） and Zhejiang University index （ZJU index）］， ultrasonic attenuation coefficient imaging （ATT）， and traditional Chinese medicine （TCM） syndrome score were statistically analyzed before treatment. Pearson correlation test was used to analyze the correlation between TG， TC， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome score， ATT， and HIS and ZJU. The patients were divided into an observation group and a control group by random number table method， with 43 cases in each group. The observation group was treated with GDL combined with sodium dimercaptopropane sulfonate （DMPS）， while the control group was only treated with DMPS as a control. After six courses of treatment， 24-hour urine copper， TC， TG， LDL-C， ApoB， HSI， ZJU， ATT， TCM syndrome score， and clinical efficiency before and after treatment were observed and compared between the two groups. The correlation between HSI and ZJU and serum TC， TG， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome scores， and ATT was analyzed. ResultPearson correlation analysis showed that serum TC （r = 0.811）， TG （r = 0.826）， LDL-C （r = 0.802）， ApoB （r = 0.820）， ALT （r = 0.497）， ALT/AST （r = 0.826）， TCM syndrome score （r = 0.716）， and ATT （r = 0.736） were positively correlated with HSI （P<0.01）， while AST， BA， and GGT had no significant correlation with HSI. TC （r = 0.718）， TG （r = 0.765）， LDL-C （r = 0.667）， ApoB （r = 0.699）， ALT/AST （r = 0.403）， TCM syndrome score （r = 0.666）， and ATT （r = 0.684） were positively correlated with ZJU （P<0.01）. ALT， AST， BA， and GGT had no significant correlation with ZJU. The total effective rate of the observation group was 86.05 （37/43）， and that of the control group was 72.09% （31/43）. The total effective rate of the observation group was higher than that of the control group （Z = -2.301， P<0.05）. After treatment， the 24-hour urine copper of the two groups increased significantly. The levels of TC， TG， LDL-C， and ApoB were significantly decreased， and the HSI， ZJU， and ATT were significantly decreased （P<0.01）. Compared with those in the control group after treatment， the above indexes improved better in the observation group （P<0.05， P<0.01）. ConclusionGDL can effectively improve the level of copper and lipid metabolism in patients with WD， with high clinical safety and good clinical application value. The prediction model of hepatic steatosis can effectively reflect the degree of abnormal lipid metabolism in WD.
