ObjectiveTo investigate the migration and distribution characteristics of chemical constituents in blood and hippocampal tissues before and after vinegar processing of Citri Reticulatae Pericarpium Viride(CRPV), and to explore the potential material basis and mechanisms underlying their regulatory effects on emotional disorders by comparing the effects of raw and vinegar-processed products of CRPV. MethodsUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) was employed to characterize and identify the chemical constituents of raw and vinegar-processed products of CRPV extracts, as well as their migrating components in blood and hippocampal tissues after oral administration. Reference standards, databases, and relevant literature were utilized for compound annotation, with data processing performed using PeakView 1.2 software. Seventy male C57BL/6 mice were randomly divided into seven groups, including the blank group, model group, diazepam group(2.5 mg·kg-1), raw CRPV low/high dose groups(0.6, 1.2 g·kg-1), and vinegar-processed CRPV low/high dose groups(0.6, 1.2 g·kg-1), with 10 mice per group. Except for the blank group, all other groups underwent chronic restraint stress(2 h·d-1) for 20 d. Each drug-treated group received oral administration at the predetermined dose starting 10 d after modeling, with a total treatment duration of 10 d. Following model-based drug administration, mice underwent open-field, forced swimming, and elevated plus maze tests. After anesthesia with isoflurane, whole brains were collected from each group of mice, and hippocampi were dissected. Reactive oxygen species(ROS) level in hippocampal tissues was quantified by enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE) staining was used to observe hippocampal tissue morphology. Immunofluorescence was performed to detect neuronal nuclei(NeuN) and peroxisome proliferator-activated receptor alpha(PPARα) expressions in hippocampal tissue. Then, pharmacodynamic evaluations were conducted to assess the effects of raw and vinegar-processed CRPV on mood disorders, exploring the potential mechanisms. ResultsVinegar processing caused significant changes in the chemical composition of CRPV, with 18 components showing increased relative content and 35 components showing decreased relative content. The primary changes occurred in flavonoid compounds, including 20 flavonoids, 20 flavonoid glycosides, 3 triterpenes, 3 phenolic acids, 1 alkaloid, and 6 other compounds. Twenty-one components were detected in blood(15 methoxyflavones, 4 flavonoid glycosides, and 2 phenolic acids), with 17 shared between raw and vinegar-processed CRPV. Seven components reached hippocampal tissues(all common to both forms). In regulating emotional disorders, Vinegar-processed CRPV exhibited superior antidepressant-like effects compared to raw products. HE staining revealed that both treatments improved hippocampal neuronal morphology, particularly in the damaged CA1 and CA3 regions. Immunofluorescence and ELISA analyses demonstrated that both raw and vinegar-processed CRPV significantly modulated NeuN and PPARα expressions in hippocampal tissue while alleviating oxidative stress induced by excessive ROS(P<0.05). ConclusionThe chemical composition of CRPV undergoes changes after vinegar processing, but the migrating components in blood and hippocampus are primarily methoxyflavonoids. These components may serve as the potential material basis for activating the PPARα pathway, thereby negatively regulating ROS generation in the hippocampus, reducing oxidative stress, and promoting the development of NeuN-positive neurons. These findings provide experimental evidence for enhancing quality standards, pharmacodynamic material research, and active drug development of raw and vinegar-processed CRPV.

Atherosclerosis (AS) is the main pathological basis of cardiovascular diseases and seriously threatens human quality of life. Its prevention and treatment urgently need breakthroughs. The inflammatory response, which runs through the physiological and pathological evolution process of AS, is one of the important mechanisms for AS occurrence. Currently, the treatment methods for AS in Western medicine are relatively mature. However, they have adverse reactions such as abnormal liver and kidney function, drug tolerance, target vessel restenosis, and stent thrombosis, which remain the key bottleneck restricting clinical efficacy. Traditional Chinese medicine (TCM), characterized by multiple components, multiple targets, and multi-pathway synergy, shows unique clinical application potential and efficacy advantages in the intervention of AS. This article reviewed the research progress of TCM in intervening in AS by regulating inflammatory-related signaling pathways, such as nuclear factor-κB (NF-κB), Toll-like receptors (TLRs), mitogen-activated protein kinase (MAPK), and Janus kinase/signal transducer and activator of transcription (JAK/STAT), in the past five years. It summarized the combined mechanism of action of TCM monomers, TCM pairs, and compound preparations in inhibiting the inflammatory cascade reaction through multiple targets, regulating lipid metabolism disorders, and improving vascular endothelial dysfunction and the imbalance of the microenvironment. It deepened the research on the molecular mechanism of TCM in anti-AS, so as to provide a scientific basis for the clinical transformation application and related theoretical research of TCM in anti-AS.

OBJECTIVE To evaluate the efficacy and safety of rituximab (RTX) in the treatment of primary Sjögren syndrome (pSS). METHODS Randomized controlled trials (RCTs) on the effects of RTX (trial group) versus placebo (control group) in the treatment of pSS were searched from the Cochran Library, PubMed, Embase, Medline, Web of Science, VIP, CNKI, Wanfang, and other databases during the inception to February 2024. After literature screening and quality evaluation, meta-analysis was performed by using RevMan 5.3 software. RESULTS Seven RCTs were finally included, involving a total of 518 patients. Results of meta-analysis showed that European League Against Rheumatism Sjögren syndrome disease activity index (ESSDAI) score [MD=-1.17, 95%CI(-1.52, -0.82), P<0.000 01] and oral dryness visual analogue scale (VAS) score [MD=-3.97, 95%CI (-5.08, -2.86), P<0.000 01] in the trial group were significantly lower than the control group; unstimulated salivary flow rate [SMD=0.64, 95%CI(0.41, 0.87), P<0.000 01] and Schirmer score [MD=0.19, 95%CI(0.18, 0.20), P<0.000 01] were significantly higher than the control group. There was no statistical significance in response rate [RD=0.10, 95%CI(-0.04, 0.23), P=0.16], fatigue VAS score [MD=-12.50, 95%CI(-35.14, 10.15), P=0.28], European League Against Rheumatism Sjögren syndrome patient reported index (ESSPRI) score [MD=0.33, 95%CI(-0.53, 1.18), P=0.46], Short-form 36 health survey physical component summary (SF36-PCS) score [MD=0.90, 95%CI(-2.97, 4.78), P=0.65], SF-36 mental component summary (SF36-MCS) score [MD=0.11, 95%CI(-0.41, 0.63), P=0.68], total salivary gland ultrasound score [SMD=-1.91, 95%CI(-4.01, 0.19), P=0.07] or the incidence of adverse drug reactions [OR=1.15,95%CI(0.62,2.13),P=0.66] between 2 groups. CONCLUSIONS RTX has advantages in the improvement of ESSDAI score, unstimulated salivary flow rate, Schirmer score and oral dryness VAS score in pSS patients, and has a good safety profile. However, it did not exhibit significant improvement in fatigue VAS score, ESSPRI score, SF36-PCS score, SF36-MCS score or response rates.

BACKGROUND:Agomelatine is a clinically proven treatment for neuropsychiatric symptoms,such as anxiety and depression.Furthermore,our previous study has demonstrated that agomelatine ameliorates cognitive behaviors,hippocampal synaptic plasticity,and brain pathology in a mouse model of Alzheimer's disease.However,it remains unclear whether agomelatine can improve anxiety and depression-like behaviors in Alzheimer's disease model mice. OBJECTIVE:To investigate the improving effects of agomelatine on anxiety-and depression-like behaviors in APP/PS1 transgenic mice and its underlying molecular mechanisms. METHODS:(1)Eighteen APP/PS1 transgenic mice were randomly divided into model control group(n=9)and model intervention group(n=9).Another wild-type mice were randomized into control group(n=9)and intervention group(n=9).Model intervention group and intervention group were intraperitoneally injected with 10 mg/kg agomelatine per day for 31 continuous days.Behavioral experiments,including the elevated cross maze and forced swimming tests,and mRNA sequencing of the hippocampus were then performed.(2)Mouse hippocampal neuronal cell lines(HT22)and brain microvascular endothelial cell lines(bEnd.3)were cultured and divided into four groups:blank group without any drug,drug group with 20 μmol/L agomelatine,model group with 10 μmol/L β-amyloid 1-42,and experimental group with 10 μmol/L β-amyloid 1-42+20 μmol/L agomelatine.After 24 hours of incubation,protein expression of S416p-tau and S9p-GSK3β in HT22 cells was detected by immunoblotting,and protein expression of low-density lipoprotein receptor-related protein 1 and glycosylation end-product receptor in bEnd.3 cells was detected by immunoblotting. RESULTS AND CONCLUSION:In the elevated plus maze test,the time spent in the open arms(P<0.01)and the entries into open arms(P<0.05)in the mice of model control group were evidently lower than those in the control group,whereas those were obviously increased in the model intervention group compared with the model control group(P<0.05).Forced swimming test results showed that the immobile time exhibited a marked increase in the model control group compared with the control group(P<0.05),but it was significantly decreased in the model intervention group compared with the model control group(P<0.05).Hippocampal tissue mRNA sequencing showed that agomelatine enhanced the expression of low-density lipoprotein receptor-related protein 1 in the hippocampus of APP/PS1 mice.Western blot analysis revealed that the level of S416p-tau in HT22 cells was higher in the model group than the blank group(P<0.05),while it was markedly decreased in the experimental group compared with the model group(P<0.05);the level of S9p-GSK3β in HT22 cells was higher in the drug group than the blank group(P<0.05)as well as higher in the experimental group than the model group(P<0.05).Moreover,the expression of low-density lipoprotein receptor-related protein 1 in bEnd.3 cells was higher in the experimental group than the model group(P<0.05).To conclude,agomelatine can alleviate anxiety-and depression-like behaviors in Alzheimer's disease mice by promoting the clearance of β-amyloid and phosphorylated tau.

BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

ObjectiveThis study aimed to investigate the intervention effect of Renqing Mangjue on the malignant transformation of gastric mucosal epithelial cells induced by N-methyl-N′-nitro-N-nitrosoguanidine (MNNG) and to explore its molecular mechanism in preventing precancerous lesions of gastric cancer based on the cyclic guanosine monophosphate (cGMP)/protein kinase G (PKG)/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway. MethodsHuman gastric mucosal epithelial cells (GES-1) were initially induced by MNNG to establish a precancerous cell model (MC cells). The effective concentration of MNNG for inducing malignant transformation in GES-1 cells was screened using the cell proliferation activity decection (CCK-8) assay, and the effective concentration of Renqing Mangjue for inhibiting the proliferation of transformed GES-1 cells was also determined. GES-1 cells were divided into a blank control group, a model group, and treatment groups with Renqing Mangjue at concentrations of 1, 3, 10, and 30 mg·L-1. Furthermore, the effects of Renqing Mangjue on the migratory ability and epithelial-mesenchymal transition (EMT) characteristics of GES-1 malignant transformed cells were evaluated using Transwell migration assays, wound healing assays, and real-time quantitative reverse transcription polymerase chain reaction (Real-time PCR). Additionally, candidate chemical components and target sites of Renqing Mangjue were obtained from the TCMIP v2.0 database, and disease targets at various stages of gastric cancer precursors were sourced from the Gene Expression Omnibus (GEO) database. Pathway enrichment analysis was performed using the Metascape database to predict the potential mechanisms of action of Renqing Mangjue. Finally, the protective mechanism of Renqing Mangjue against gastric cancer precursors was validated through Western blot analysis. ResultsAt a concentration of 20 μmol·L-1, MNNG exhibited an inhibition rate of approximately 50% on GES-1 cells (P<0.01), and at this concentration, the GES-1 cells displayed biological characteristics indicative of malignant transformation. In contrast, Renqing Mangjue had no significant effect on the proliferation of normal GES-1 cells, but significantly inhibited the proliferation of MC cells (P<0.01) and markedly reduced their migratory capacity (P<0.01). Moreover, it also increased the mRNA expression level of E-cadherin during the EMT process (P<0.05), while inhibiting the expression of both N-cadherin and the transcription factor Snail mRNA (P<0.05, P<0.01). Network predictions suggested that Renqing Mangjue may prevent gastric cancer precursors through modulating the cGMP/PKG and MAPK/ERK signaling pathways. Furthermore, Western blot results indicated that Renqing Mangjue upregulated the expression of PKG and NPRB (B-type natriuretic peptide receptor) proteins in the cGMP/PKG pathway (P<0.01), while downregulating the expression of the downstream proteins MEK and ERK (P<0.05, P<0.01). ConclusionIn summary, Renqing Mangjue can prevent gastric cancer precursors by inhibiting the proliferation and migration of malignant transformed GES-1 cells, thereby delaying the EMT process. The underlying mechanisms may be related to the activation of the cGMP/PKG pathway and the inhibition of the MEK/ERK signaling pathway.

Depression is a high-incidence mental disorder with complex causes and multifaceted pathogenic mechanisms. Its pathogenesis has not yet been fully elucidated, which has hindered the development of novel and highly effective antidepressant drugs. This condition severely affects human physical and mental health while imposing a significant socio-economic burden. At present, several hypotheses exist regarding the pathogenesis of depression, including monoamine neurotransmitter imbalances, neurotrophic factor deficiencies, neural plasticity impairments, glutamate dysregulation, neuroinflammatory disorders, gut microbiota imbalances, and mitochondrial autophagy dysfunction. Currently, most clinical antidepressants are monoamine neurotransmitter reuptake inhibitors. Although they exhibit certain therapeutic effects, they are associated with significant drawbacks, such as severe adverse reactions and poor patient compliance. In contrast, traditional Chinese medicine (TCM), characterized by its multi-targeted effects, mild efficacy, and minimal side effects, has demonstrated significant advantages in the treatment of depression. Chinese medicine Polygalae Radix possesses the functions of calming the mind, enhancing cognitive functions, harmonizing the heart and kidneys, and dispelling phlegm to open orifices. It is often included in compound prescriptions for the clinical treatment of depression. Based on current hypotheses regarding the pathogenesis of depression, this paper systematically reviews research progress on the antidepressant mechanisms of Polygalae Radix from multiple perspectives, including its active components, its use in herbal pairings, and its inclusion in TCM compound prescriptions. This review aims to provide a scientific basis for the clinical application of Polygalae Radix in antidepressant therapy and to serve as a reference for the modernization of its antidepressant research.

Guided by the turbidity toxin theory, it is believed that the key pathogenesis of constipation-predominant irritable bowel syndrome is the obstruction of turbidity toxin and the disruption of intestinal function. Treatment is based on the principles of dispelling turbidity toxin and promoting intestinal function. The clinical patterns can be divided into three types, turbidity toxin heat accumulation pattern, turbidity toxin combined with liver depression and qi stagnation pattern, and turbidity toxin combined with qi and yin deficiency pattern. The treatment can respectively use self-prescribed Tongfu Jiangzhuo Formula (通腑降浊方) to clear heat and unblock the bowels, direct the turbid downward and resolve toxins; use self-prescribed Shugan Jiangzhuo Formula (疏肝降浊方) to soothe the liver and move qi, direct the turbid downward and resolve toxins; use self-prescribed Mazhi Jiangzhuo Formula (麻枳降浊方) to boost qi and nourish yin, moisten the intestines to remove turbidity and resolve toxins.
