Irritable bowel syndrome （IBS） is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years， traditional Chinese medicine （TCM） has made progress in multiple aspects of IBS research and treatment， including syndrome distribution， development of TCM formulas， clinical efficacy evaluation， external therapies， and psychosocial regulation. However， it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria， and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment， combining TCM external therapies such as acupuncture， moxibustion and acupoint application）， and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies， artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas， so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

AIM:To evaluate the clinical efficacy of 0.05% cyclosporine eye drops(Ⅱ)combined with sodium hyaluronate eye drops in treating patients with type 2 diabetes mellitus(T2DM)and moderate-to-severe dry eye.METHODS:A total of 120 T2DM patients(120 eyes)with moderate-to-severe dry eye, treated at the endocrinology and ophthalmology departments at the Affiliated Hospital of Xuzhou Medical University from January 2024 to September 2024, were enrolled in the study. The patients were randomly divided into two groups: combination group [0.05% cyclosporine eye drops(Ⅱ)+ sodium hyaluronate eye drops] and control group(sodium hyaluronate eye drops alone), with 60 cases(60 eyes)in each group. Assessments were conducted at baseline and at 1, 2, and 3 mo post-treatment, including the ocular surface disease index(OSDI), non-contact tear meniscus height(NITMH), first non-invasive tear breakup time(NIBUTf), meibomian gland loss score, lipid layer thickness grade, conjunctival hyperemia grade, and corneal fluorescein staining(FL)score. At 3 mo after treatment, changes in tear inflammatory factors were observed, and corneal subbasal nerve plexus(SBN)morphology/density were analyzed using in vivo confocal microscopy(IVCM).RESULTS:At 1, 2, and 3 mo post-treatment, both groups showed statistically significant increases in NITMH and NIBUTf compared to baseline(all P<0.05), with greater improvement observed in the combination group(both P<0.05). OSDI and FL scores significantly decreased from baseline(all P<0.05), with more pronounced reductions in the combination group(both P<0.05). Meibomian gland loss scores showed no significant improvement in either group(all P>0.05). At 3 mo after treatment, tear levels of interleukin 6(IL-6)and matrix metalloproteinase-9(MMP-9)significantly decreased in both groups(all P<0.001), with a greater reduction noted in the combination group(both P<0.001). The combination group displayed increased corneal nerve branch density and nerve fiber density, along with decreased nerve tortuosity and dendritic cell(DC)density compared to baseline(all P<0.001), while the control group did not show significant changes(all P>0.05).CONCLUSION: The combination of 0.05% cyclosporine eye drops(Ⅱ)and sodium hyaluronate eye drops significantly improves clinical outcomes in T2DM patients with moderate-to-severe dry eye. This treatment effectively alleviates ocular surface inflammation, restores corneal nerve morphology and density, and demonstrates a favorable safety profile.

Traditional four examinations of traditional Chinese medicine （TCM） are based on the symptoms and signs of patients， which are the advantages of TCM but also have shortcomings. Chronic kidney disease has the characteristics of insidiousness， long-term， deficiency and variability during its onset， which are difficult to be intervened in time based on only symptoms， therefore it is necessary to extend the application of the four examinations in the diagnosis and treatment process of chronic kidney disease. Based on the background of the continuous development of TCM syndrome differentiation techniques， this article proposed the extension and application strategies of the traditional four examinations in chronic kidney disease， including the incorporation of microscopic syndrome differentiation to identify the causes of kidney disease and prevent symptom deterioration； the utilization of accurate examination information enhanced by artificial intelligence for controlling development of existing disease； the integration of disease differentiation and syndrome differentiation to summarize clinical rules towards using constant to measure variation； and the establishment of a kidney disease database for the storage of four examinations information to prevent recurrence after recovery. The four above extension and application strategies can be used to achieve the long-term management and treatment effects of timely and early diagnosis， dynamic observation of the condition， accurate application of intervention， and strengthened prognosis assessment in the diagnosis and treatment of chronic kidney disease， and expand the advantages of TCM in the prevention and treatment of chronic kidney disease.

ObjectiveThis study aims to reveal the mechanism of liver and kidney injuries caused by Dictamni Cortex and its interrelationship by metabonomics analysis of liver and kidney via ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF-MS）. MethodsThe content of the marker compounds of Dictamni Cortex was measured by high-performance liquid chromatography （HPLC） to carry out quality control. Sprague Dawley （SD） rats were randomly divided into a blank group （normal saline）， an administration group （0.9， 2.7， 8.1 g·kg^-1）， and a high-dose withdrawal control group， with eight rats in each group. Continuous administration was performed once daily for 28 days. The liver and kidney injuries caused by each administration group were assessed by organ indices， pathological observations， and serum and plasma biochemical indices measured by enzyme-linked immunosorbent assay （ELISA）. The potential biomarkers of liver and kidney injuries caused by Dictamni Cortex were screened， and pathway enrichment analysis and correlation analysis were performed based on UPLC-Q-TOF-MS. ResultsCompared with the blank group， both the medium- and low-dose groups showed insignificant damage to the liver and kidney of rats. The high-dose group exhibited the most serious damage， and the level of liver and kidney function indices ［alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， creatinine （Cr）， and blood urea nitrogen （BUN）］ and serum inflammatory indices （［interleukin 1β （IL-1β）， IL-6， and tumor necrosis factor-α （TNF-α）］ in the serum were significantly changed （P<0.01）. The liver and kidney metabolism pathways and differential metabolites were quite different. Among them， phenylalanine metabolism， niacin and nicotinamide metabolism， and glycerophospholipid metabolism were common pathways. Correlation analysis of differential metabolites showed that there were significant correlations among disorders of 4′-Phosphopantothenoylcysteine， PC （16∶0/15∶0）， phenylethylamine， arachidonic acid， and linoleic acid in liver and kidney tissue. ConclusionThe decoction of Dictamni Cortex can cause liver and kidney injuries， and its mechanism may be related to oxidative stress and lipid metabolism disorders. The correlation of differential metabolites indicates the interaction between liver and kidney injuries.

ObjectiveTo explore the mechanism of the immunotoxicity induced by dictamnine （DIC） in rats and the recovery effect after drug withdrawal by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry， thereby providing a theoretical basis for elucidating the toxic mechanism of DIC. MethodsSD rats were randomized into blank （normal saline）， DIC （10 mg·kg^-1）， and DIC withdrawal （recovery period） groups （n=8）. The rats were continuously treated for 7 days， once a day， and the body weight and organ weight were recorded. The levels of interleukin-1 （IL-1）， IL-6， and tumor necrosis factor-α （TNF-α） in the serum and immunoglobulin A （IgA）， immunoglobulin G （IgG）， and immunoglobulin M （IgM） in the spleen were determined by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was used to observe the pathological changes in the spleen. ultra performance liquid chromatography quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS） was employed to screen the potential biomarkers of immune inflammation caused by DIC， and pathway enrichment analysis and correlation analysis were performed. The mRNA levels of IL-1β， TNF-α， lysophosphatidylcholine acyltransferase 2 （LPCAT2）， and farnesoid X receptor （FXR） in the serum were determined by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， the DIC group showed elevated levels of IL-1β， IL-6， and TNF-α in the serum （P<0.01）， and the DIC withdrawal group showcased lowered levels of IL-1β， IL-6， and TNF-α in the serum （P<0.01）. The levels of IgA， IgG， and IgM in the spleen of rats in the DIC group were decreased （P<0.01）， while those in the DIC withdrawal group were recovered （P<0.05， P<0.01）. Untargeted metabolomics of the serum and spleen screened out 14 common differential metabolites and 14 common metabolic pathways. The Spearman correlation analysis between differential metabolites and inflammatory factors identified PC （32∶0）， LysoPC （20∶4/0∶0）， LysoPC （P-18∶0/0∶0）， taurochenodeoxycholic acid， taurocholic acid， LysoPC ［20∶5（5Z，8Z，11Z，14Z，17Z）/0∶0］， chenodeoxycholic acid， arachidonic acid， LysoPC （18∶0/0∶0）， LysoPC （15∶0/0∶0）， LysoPC （16∶0/0∶0）， and LysoPC （17∶0/0∶0） as the biomarkers of immunotoxicity induced by DIC in SD rats. In the process of immunotoxicity caused by DIC， lipid metabolism disorders such as glycerophospholipid metabolism， primary bile acid metabolism， and arachidonic acid metabolism were enriched， which was consistent with the DIC-induced inflammatory factors and pathological characteristics of the spleen. Compared with the blank group， the DIC group exhibited up-regulated mRNA levels of IL-1β， TNF-α， LPCAT2， and FXR （P<0.01）， and the up-regulation was decreased in the withdrawal group （P<0.01）. ConclusionDIC can lead to immune and inflammatory disorders. DIC withdrawal can regulate the expression of biomarkers related to serum and spleen metabolites， regulate the inflammatory metabolic pathway， reduce the inflammation level， and alleviate the metabolic disorders， thus attenuating the potential toxicity induced by DIC.

OBJECTIVES: The integrated endoplasmic reticulum stress inhibitor (ISRIB) is a selective inhibitor of the protein kinase R-like endoplasmic reticulum kinase (PERK) signaling pathway within endoplasmic reticulum stress (ERS) and can improve spatial and working memory in aged mice. Although ERS and oxidative stress are tightly interconnected, it remains unclear whether ISRIB alleviates cognitive impairment by restoring the balance between ERS and oxidative stress. This study aims to investigate the effects and mechanisms of ISRIB on lipopolysaccharide (LPS)-induced cognitive impairment in mice. METHODS: Eight-week-old male ICR mice were randomly divided into 3 groups: Normal saline (NS) group, LPS group, and ISRIB+LPS group. NS and LPS groups received daily intraperitoneal injections of normal saline for 7 days; on day 7, LPS group mice received intraperitoneal LPS (0.83 mg/kg) to establish a cognitive impairment model. ISRIB+LPS group received ISRIB (0.25 mg/kg) intraperitoneally for 7 days, with LPS injected 30 minutes after ISRIB on day 7. Cognitive ability was evaluated by the novel place recognition test (NPRT). Real-time fluorogenic quantitative PCR (RT-qPCR) was used to detect changes in nitric oxide synthase (NOS), superoxide dismutase-1 (SOD-1), and catalase (CAT) gene expression in the hippocampus and prefrontal cortex. Oxidative stress markers malondialdehyde (MDA), glutathione (GSH), and oxidized glutathione (GSSG), were measured in hippocampal and prefrontal cortex tissues. RESULTS: Compared with the NS group, mice in LPS group showed a significant reduction in novel place recognition ratio, upregulation of hippocampal NOS-1 and NOS-2 mRNA, downregulation of SOD-1 and CAT mRNA, increased MDA and GSSG, decreased GSH, and reduced GSH/GSSG ratio (all P<0.05). Compared with the LPS group, mice in ISRIB+LPS group exhibited significantly improved novel place recognition, downregulated NOS-1 and NOS-2 mRNA, upregulated SOD-1 and CAT mRNA, decreased MDA and GSSG, increased GSH, and an elevated GSH/GSSG ratio in the hippocampus (all P<0.05). No significant changes were observed in the prefrontal cortex. CONCLUSIONS ISRIB improves LPS-induced cognitive impairment in mice by restoring the oxidative/antioxidant balance in the hippocampus.

Objective To observe the effects of acupuncture at Huantiao(GB30)points and Weizhong(BL40)points combined with high-energy extracorporeal shock wave therapy(ESWT)on hip joint function and the expression of inflammation-related factors in patients with early-stage osteonecrosis of the femoral head(ONFH).Methods A total of 90 patients diagnosed with early-stage ONFH and admitted to the wards and outpatient clinics of Xi'an Trade Union Hospital from February 2021 to December 2023 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 45 patients in each group.The control group received ESWT,while the observation group received acupuncture at Huantiao points and Weizhong points in addition to ESWT.The treatment lasted for 8 weeks.After treatment,the clinical efficacy of the two groups was evaluated.Changes in traditional Chinese medicine(TCM)syndrome scores,Visual Analogue Scale(VAS)scores for pain,Harris hip scores,and internal-external rotation range of motion(I-ER ROM)of the hip joint were observed before and after treatment.Changes in levels of D-dimer(D-D),high-shear whole blood viscosity(HRV),low-shear whole blood viscosity(LRV),plasma viscosity(PV),tumor necrosis factor-α(TNF-α),and interleukin-1β(IL-1β)were compared between the two groups before and after treatment.Results(1)The total effective rate in the observation group was 95.56%(43/45),compared to 75.56%(34/45)in the control group.The observation group showed significantly better efficacy than the control group,with a statistically significant difference(P＜0.05).(2)After treatment,both groups showed significant improvements(P＜0.05)in scores for hip dull pain,joint stiffness,walking fatigue,and soreness of the waist and knees,and the observation group was significantly superior to the control group in improving these scores,with a statistically significant difference(P＜0.05).(3)After treatment,both groups showed significant improvements(P＜0.05)in Harris hip scores,I-ER ROM,and VAS scores,and the observation group was significantly superior to the control group in improving these scores,with a statistically significant difference(P＜0.05).(4)After treatment,both groups showed significant improvements(P＜0.05)in serum TNF-α and IL-1β levels,and the observation group was significantly superior to the control group in improving these levels,with a statistically significant difference(P＜0.05).(5)After treatment,both groups showed significant improvements(P＜0.05)in serum D-D,HRV,LRV,and PV levels,and the observation group was significantly superior to the control group in improving these levels,with a statistically significant difference(P＜0.05).Conclusion Acupuncture at Huantiao points and Weizhong points combined with high-energy ESWT can significantly improve hip joint function,enhance hemorheological status,alleviate hip pain,increase I-ER ROM,reduce inflammatory responses,and lower serum TNF-α and IL-1β levels in patients with early-stage ONFH.The treatment shows significant efficacy.

Objective:To investigate the gait characteristics of patients with early Parkinson′s disease (PD) under cognitive dual task, and to provide sensitive kinematic indicators for the early diagnosis, timely treatment and reasonable rehabilitation of PD.Methods:A total of 62 outpatients and inpatients with early non-tremor Parkinson′s disease in Shijingshan Branch of Beijing Chaoyang Hospital Affiliated to Capital Medical University from September 2021 to August 2023 were selected as experimental group (PD group), and 62 healthy controls with comparable age composition ratio were selected as control group. The baseline data, Montreal Cognitive Assessment Scale scores, and the gait assessment scores of the motor part of the Unified Parkinson′s Disease Rating Scale were compared between the 2 groups. The wearable gait analysis device was used to collect the gait parameters of the 2 groups of subjects under single task and dual task, and the foot kinematic characteristics of the patients with early PD were quantified. Independent sample t test and Mann-Whitney U test were used to analyze the gait parameters of the 2 groups. The statistically significant variables were included in Logistic regression analysis to explore the association between gait parameters and PD. Finally, the diagnostic value of the variables was estimated by receiver operating characteristic (ROC) curve analysis. Results:Gait spatio-temporal parameters (per gait cycle): (1) The gait speed of the PD group was slower than that of the control group [(1.01±0.12) m/s vs (1.22±0.18) m/s, t=-7.526] during single task walking. The bipedal support time in the PD group was significantly longer than that in the control group [(0.29±0.05) s vs (0.22±0.06) s, t=6.659]. The differences were both statistically significant (both P<0.001). (2) During dual-task walking, PD patients showed slower gait speed [(0.88±0.11) m/s vs (1.19±0.16) m/s, t=-12.158, P<0.001]. The bipedal support time in the PD group was longer than that in the control group [(0.36±0.05) s vs (0.22±0.05) s, t=12.828, P<0.001]. PD patients had shorter stride length [(109.20±6.21) cm vs (112.77±5.87) cm, t=-3.203, P=0.010]. Stride frequency in the PD group was higher than that in the control group [(114.45±7.10) steps/min vs (110.87±7.16) steps/min, t=2.724, P=0.020]. The single leg support time was longer than that of the control group [(0.49±0.12) s vs (0.45±0.06) s, t=2.643, P=0.020] , and the differences were statistically significant. Gait kinematics parameters: (1) During single task walking, the maximum angle of foot movement in the sagittal plane in the PD group was smaller than that in the control group (17.19°±2.37° vs 19.71°±2.92°, t=-4.691, P<0.001). The minimum angle of movement in the sagittal plane was smaller than that in the control group (-67.08°±4.63° vs -70.10°±3.94°, t=0.395, P=0.001). The minimum horizontal angle of the foot during exercise in the PD group was lower than that in the control group (9.08°±4.02° vs 11.80°±3.60°, t=-3.461, P<0.001). The minimum angle of the foot coronal plane in the PD group was smaller than that in the control group (-10.55°±2.87° vs -12.04°±2.31°, t=2.831, P=0.030; the negative sign only represents the movement direction). The touch angle of the foot in the PD group was significantly lower than that in the control group (11.14°±2.78° vs 12.78°±3.57°, t=-2.779, P=0.030). (2) During dual-task walking, the maximum sagittal angle (15.44°±2.54° vs 18.99°±2.71°, t=-6.673, P<0.05), the minimum angle of sagittal plane (-65.68°±4.73° vs -70.02°±4.04°, t=-4.747, P<0.001; the negative sign only represents the direction of movement), the minimum coronal movement angle (-11.15°± 2.99° vs -13.18°±2.50°, t=3.642, P=0.020), the touch angle (11.01°±3.10° vs 12.83°±4.01°, t=-2.438, P=0.010), the minimum horizontal angle (8.83°±4.04° vs 11.83°±3.63°, t=-3.776, P<0.001), and the change of the angle from the ground (-65.00°±3.54° vs -67.06°±3.61°, t=3.133, P<0.001) in the PD group were all smaller than that in the control group. The differences were all statistically significant. Logistic regression analysis showed that step frequency was positively correlated with PD ( OR=1.124,95% CI 1.040-1.201, P=0.001), minimum angle of coronal plane was positively correlated with PD ( OR=1.501, 95% CI 1.040-2.151, P=0.030). Stride length was negatively correlated with PD ( OR=0.902, 95% CI 0.830-0.978, P=0.010). ROC curve was used to evaluate the diagnostic value of step frequency, stride length and minimum angle of coronal plane. For step frequency, when the maximum Youden index was 0.880, the best cut-off value to distinguish the PD group from the control group was 115.000, the sensitivity was 0.577, the specificity was 0.710, and the area under the curve was 0.656. For the minimum coronal angle, when the maximum Youden index was 0.251, the best cut-off value was -12.575, the sensitivity was 0.728, the specificity was 0.531, and the area under the curve was 0.670. For stride length, when the maximum Youden index was 0, the best cut-off value was 100.91, the sensitivity was 0.950, the specificity was 0.050, and the area under the curve was 0.300. Conclusions:Some gait parameters such as step frequency and minimum angle of coronal plane can be used as kinematic markers to reflect the gait characteristics of early PD, which may be helpful in tracking and evaluating the gait disorder characteristics of early PD patients and predicting the risk of PD. Some gait parameters of PD patients are significantly different from those of healthy people during cognitive-motor dual-task walking.

Objective: The study aims to investigate the impact of moderate intensity gymnastics on the development of executive function in children aged 5-6, thereby providing a theoretical foundation for exercise interventions targeting executive function. Methods: A total of 63 preschool children, randomly seleted from 3 senior classes in a private kindergarten in Shangqiu, were randomly allocated to the intervention group ( n =31) and control group ( n =32). Children in the intervention group participated in 60 minute gymnastics at a moderate intensity, three times per week, for a total duration of 12 weeks. Concurrently, myzone technology was utilized to monitor exercise intensity throughout the entire intervention period. Children in the control group maintained their regular activities. Inhibitory control (Flanker task), working memory (Empty house task), and cognitive flexibility (Dots task) were assessed before and after the experiment. Results: There was no statistically significant difference in the performance of inhibitory control, working memory, and cognitive flexibility tasks between the two groups of children before intervention ( P >0.05) .The results of covariance analysis revealed significant differences in reaction time [(782.88±24.29，805.13±23.74；719.90±119.99， 833.55± 177.87；1 042.39±72.75，1 091.29±49.42) ms] and accuracy[(73.86±7.26)%，(67.02±8.22)%;(86.36±7.63)%，( 80.50± 9.39 )%;(76.45±9.48)%，(69.59±7.66)%] across inhibitory control, working memory, and cognitive flexibility between the intervention group and the control group ( F =6.84, 4.50，4.87, 6.11, 3.74 , 5.06 , P <0.05). The intervention effect exhibited modest effects( d =0.17-0.74). Conclusions Moderate intensity gymnastics can make modest or moderate effect on improving children s executive function. Brain imaging technology can be incorporated into future research designs to investigate the underlying mechanisms of gymnastics impact on the brain structure and executive function in young children.

Concurrent chemoradiotherapy (CCRT) refers to the simultaneous treatment of chemotherapy and radiotherapy, and the effect of radiotherapy is enhanced with low-dose chemotherapy, which can reduce tumor recurrence and metastasis and improve clinical prognosis of patients. At present, the main factors for the increase of radiosensitivity of concurrent chemotherapy is that concurrent chemotherapy prevents the repair of tumor cells, and chemotherapy and radiotherapy act on different cell cycles and have synergistic effects. However, even for patients with locally advanced cervical cancer (LACC) who have undergone CCRT, the 5-year survival rate is only 60%, which is still not ideal. In order to improve the efficacy, researchers have conducted a series of exploratory studies, which consist of the combination of targeted drugs and immunodrugs, and neoadjuvant regimens before CCRT, etc. Although targeted or immunologic drugs are effective treatment of LACC, in view of the lack of large-scale evidence-based medical evidence, multi-center prospective and randomized phase III clinical trials and high-level articles are needed to improve the level of evidence-based medicine. This consensus summarizes several key evidence-based medical studies published recently, especially the clinical research progress in targeted and immunological therapies, providing reference for domestic peers.
