ObjectiveTo investigate whether Shixiaosan can improve neurological function and inhibit ferroptosis in rats with cerebral ischemia-reperfusion injury （CIRI） by regulating the nuclear factor E₂-related factor 2 （Nrf2）/solute carrier family 7 member 11 （SLC7A11）/glutathione peroxidase 4 （GPX4） pathway. MethodsA rat model of CIRI was established using the intraluminal filament method. Briefly， cervical blood vessels were separated， branches of the external carotid artery were ligated， and the common carotid artery and internal carotid artery were clamped. A nylon filament was inserted through the opening of the external carotid artery to the origin of the middle cerebral artery to block blood flow and induce cerebral ischemia. After 60-120 min of ischemia， the filament was withdrawn to restore blood flow， and the external carotid artery incision was ligated. The rats were divided into a CIRI group， a Shixiaosan low-dose （-L） group （intragastric administration of 1.26 g·kg^-1 Shixiaosan）， a Shixiaosan high-dose （-H） group （intragastric administration of 2.52 g·kg^-1 Shixiaosan）， a donepezil hydrochloride tablet （DON） group （intragastric administration of 0.45 mg·kg^-1 DON）， and a Shixiaosan -H + Nrf2 inhibitor （ML385） group （intragastric administration of 2.52 g·kg^-1 Shixiaosan combined with intraperitoneal injection of 30 mg·kg^-1 ML385）. An additional 12 rats underwent cervical artery separation followed by incision suturing and served as the control group. Equal volumes of double-distilled water were administered to the CIRI and control groups. Neurological function impairment was assessed using the modified Garcia JH score. Magnetic resonance imaging was used to determine the cerebral infarct volume ratio. Hematoxylin-eosin （HE） staining and Prussian blue staining were performed to observe neuronal injury and iron accumulation in the ischemic penumbra， respectively. Transmission electron microscopy was used to examine the ultrastructure of neuronal mitochondria in the ischemic penumbra. Commercial kits were used to measure ferrous iron （Fe²⁺）， malondialdehyde （MDA）， reduced glutathione （GSH） content， and reactive oxygen species （ROS） activity in the ischemic penumbra. The BODIPY （581/591） C11 fluorescent probe was used to detect intracellular lipid peroxidation levels. Western blot was performed to detect protein expression levels of Nrf2， SLC7A11， GPX4， transferrin receptor 1 （TFRC）， ferritin heavy chain （FHC）， and ferritin light chain （FLC） in the ischemic penumbra. ResultsCompared with the control group， the CIRI group exhibited neuronal injury in the ischemic penumbra， characterized by reduced neuron numbers， nucleolar shrinkage， and interstitial edema. Marked iron accumulation was observed in the tissue. Neuronal mitochondria showed atrophy and rupture， with reduced mitochondrial cristae and increased membrane density. The cerebral infarct volume ratio， Fe²⁺ content， MDA content， ROS activity， and lipid peroxidation levels were increased， whereas the modified Garcia JH score， GSH content， and protein expression levels of Nrf2， SLC7A11， GPX4， FHC， and FLC were decreased， and TFRC protein expression was increased （P<0.05）. Compared with the CIRI group， the Shixiaosan -L group， Shixiaosan -H group， and DON group showed attenuated neuronal injury in the ischemic penumbra， reduced iron accumulation， alleviated mitochondrial damage， decreased cerebral infarct volume ratio， Fe²⁺ and MDA contents， ROS activity， and lipid peroxidation levels， as well as increased modified Garcia JH scores， GSH content， and protein expression levels of Nrf2， SLC7A11， GPX4， FHC， and FLC， while TFRC protein expression was decreased （P<0.05）. The magnitude of changes in all indicators was greater in the Shixiaosan -H group than in the Shixiaosan -L group （P<0.05）. Compared with the Shixiaosan -H group， all measured indicators in the Shixiaosan -H + ML385 group showed opposite trends （P<0.05）. ConclusionShixiaosan may inhibit ferroptosis and restore neurological function in rats with CIRI by activating the Nrf2/SLC7A11/GPX4 pathway.

AIM:To investigate the effects of high-altitude hypoxic exposure on retinal injury and the associated changes in oxidative stress-related indicators in rats. METHODS: Twenty-four healthy male Sprague-Dawley(SD)rats were randomly divided into a plain group and a high-altitude group, with 12 rats(24 eyes)in each group. Rats in the plain group were housed under normoxic conditions in an SPF-grade animal facility, whereas rats in the high-altitude group were placed in a special environmental chamber simulating an altitude of 6 000 m for 7 d. Optical coherence tomography(OCT)was used to assess retinal layer architecture and quantify retinal thickness. Hematoxylin-eosin(HE)staining was performed to observe retinal histopathological changes. Immunofluorescence(IF)was used to detect the expression of hypoxia-inducible factor-1α(HIF-1α)in retinal tissue. Transmission electron microscopy(TEM)was applied to examine the ultrastructure of retinal ganglion cells(RGCs). Enzyme-linked immunosorbent assay(ELISA)was used to measure the levels of malondialdehyde(MDA), total superoxide dismutase(T-SOD), and reduced glutathione(GSH)in retinal tissue. In addition, intracellular reactive oxygen species(ROS)levels in retinal tissue were assessed using the 2',7'-dichlorodihydrofluorescein diacetate(DCFH-DA)fluorescent probe. RESULTS: OCT examination revealed disorganized retinal architecture in the high-altitude group, with increased inner and middle ring thickness and decreased outer ring thickness compared with the plain group(all P<0.05). HE staining showed varying degrees of retinal layer damage, blurred layer boundaries, loosely arranged RGCs, and partial cellular necrosis in the high-altitude group. IF analysis demonstrated significantly increased HIF-1α expression in the inner nuclear layer of the high-altitude group(P<0.01). TEM revealed mitochondrial swelling, disrupted cristae, and reduced matrix electron density in RGCs of the high-altitude group. ELISA and fluorescence probe assays showed significantly elevated MDA levels and ROS fluorescence intensity, accompanied by decreased T-SOD and GSH levels in the retinal tissue of the high-altitude group(all P<0.05). CONCLUSION: Exposure to a high-altitude hypoxic environment induces marked morphological and ultrastructural damage in the rat retina and significantly enhances oxidative stress, suggesting that oxidative stress may play a critical role in retinal injury induced by high-altitude hypoxia.

ObjectiveSpinal cord injury (SCI) directly impairs the regulatory function of the autonomic nervous system, induces intestinal dysfunction, and significantly reduces patients’ quality of life. Preclinical studies have shown that electroacupuncture (EA) therapy can regulate the brain-gut axis and is used to treat central nervous system diseases such as major depressive disorder, Alzheimer’s disease and Parkinson’s disease. Recent research has established that fecal microbiota transplantation (FMT) from EA-treated SCI rats restored intestinal motility and colonic morphology. However, it remains unclear whether the regulation of gut microbiota by EA therapy directly contributes to neural repair after SCI. This study aims to explore whether gut microbiota mediates the neuroprotective effect of EA in the treatment of SCI and its possible mechanism. MethodsThe study employed RNA transcriptome analysis of spinal cord tissue to characterize gene expression profiles and to identify key signaling pathways following EA treatment for SCI. Hematoxylin-Eosin (HE) staining and Nissl staining were used to observe the morphological changes in spinal cord tissue. Western blot (WB) and enzyme-linked immunosorbent assay (ELISA) were applied to detect the effects of EA on the expression of proteins related to nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3) -dependent pyroptosis. Using 16S rDNA sequencing, the study observed alterations in gut microbiota diversity and community composition in SCI rats. Prior to establishing SCI models, rats were pretreated with an antibiotic cocktail to induce gut dysbiosis, and the effects on intestinal function and spinal cord neural repair were evaluated. FMT was performed to investigate the regulatory effects of post-EA FMT on motor function, general status, liver and spleen indices, and NLRP3-mediated pyroptosis in SCI rats. ResultsEA improved motor function and reduced regulated neuronal cell death in SCI rats. Transcriptomic analysis demonstrated the activation of immune- and inflammation-related pathways post-SCI, including NOD-like receptors, nuclear factor-kappa B(NF-κB), and Toll-like receptor (TLR) pathways. EA primarily influenced intestinal inflammation and autoimmune functions. 16S rDNA sequencing illustrated that EA did not alter the diversity of gut microbiota. However, EA altered the gut microbiota composition in SCI rats, increasing Lactobacillus and Akkermansia genera while rebalancing the Firmicutes/Bacteroidetes ratio. Furthermore, depletion of gut microbiota by antibiotics disrupted the intestinal barrier, reduced the expression of intestinal barrier proteins Zonula Occludens-1 (ZO-1) and Occludin, elevated serum lipopolysaccharide-binding protein (LBP) levels, exacerbated spinal cord tissue damage, and hindered motor function recovery in SCI rats. FMT from donors treated with EA reduced LBP levels in the intestine, blood, and spinal cord of rats, inhibited the TLR4 myeloid differentiation primary response protein 88 (MyD88)-NF‑κB pathway and NLRP3-dependent pyroptosis, and improved motor function. On the other hand, FMT treatment resulted in decreased body weight and food intake, whereas FMT using EA-treated donors effectively alleviated these alterations. ConclusionEA effectively alleviated neuroinflammatory responses in rats with SCI, primarily through regulating the gut microbiota and suppressing the NLRP3-dependent pyroptosis signaling pathway.

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.

Objective: To explore the relationship of physical activity (PA) and sedentary behavior (SB) with cardiorespiratory fitness (CRF) among middle schoold students in Tibet, so as to provide empirical references for improving the cardiorespiratory fitness and health levels of adolescents in Tibet. Methods: From August to December 2020, 1 225 junior and senior high school students were selected from 2 middle schools in Lhasa, Tibet Autonomous Region, using the stratified cluster random sampling method. Triaxial accelerometers were used to evaluate PA and SB behaviors, and the 20 meter shuttle run was employed to assess CRF among the middle school students. Isochronous substitution modeling was used to analyze the associations of SB, low intensity physical activity (LPA), and moderate vigorous physical activity (MVPA) with CRF, and the saturation threshold effect in the dose response relationship between MVPA and CRF was analyzed through restricted cubic spline and two stage linear regression. Results: After adjusting for covariates such as gender, body mass index and sleep quality score, isotemporal substitution analysis showed that among junior high school students aged 13-15, replacing 30 minutes of SB ( B =1.73) or LPA ( B =2.38) with MVPA were positively associated with CRF (both P <0.05). Among senior high school students aged 16-18, replacing SB ( B =0.99) or LPA ( B =1.38) with MVPA were also positively associated with CRF (both P <0.05). Restricted cubic spline and two piecewise linear regression analyses indicated that only middle school girls aged 13-18 exhibited a saturation threshold effect between MVPA and CRF (logarithmic likelihood ratio test=0.03), with the optimal CRF improvement observed at 60 minutes of MVPA per day ( B=0.13, P ＜ 0.01). Conclusions Reducing SB and LPA while increasing MVPA can improve CRF in Tibetan middle school students. To maximize CRF improvement, middle school girls should engage in at least 60 minutes of MVPA daily.

Objective　To analyze the current situation and influencing factors of health-care seeking delay of tuberculosis patients registered in Changsha from 2019 to 2023, and to understand the current status of health-care seeking delay after the transformation of the tuberculosis prevention and treatment service model in Changsha, so as to provide reference bases for improving the patient discovery strategy and optimizing tuberculosis control and prevention measures. Methods　The case data of 23 371 tuberculosis patients registered in Changsha City from 2019 to 2023 were collected, and the time of health-care seeking delay and the rate of health-care seeking delay were calculated. Comparison of differences between groups with different characteristics using rank sum test and chi-square test, and the Cochran-Armitage method was used to analyze the trend of health-care seeking delay rate, and multifactorial analysis was carried out with the help of logistic regression model. Results　The median health-care seeking time of tuberculosis patients in Changsha City from 2019-2023 was 16 (5, 44) days, and the overall health-care seeking delay rate was 53.5%, with an overall increasing trend (Z=-7.256, P<0.001). Between-group comparisons revealed differences in health-care seeking delay time and health-care seeking delay rate between groups of patients with different gender, age group, occupation, current address, types of household registration, medical history, complication, diagnostic triage, pathogenic results and geographic accessibility (P<0.05). The results of multifactorial analysis showed that compared to the<25 years age group, the 25-<65 years age group (OR=1.579, 95%CI: 1.490-1.669) and the ≥65 years age group (OR=2.016，95%CI: 1.918-2.113) had a higher risk of health-care seeking delay, presence of complication (OR=1.213，95%CI:1.141-1.285), positive pathology (OR=1.503, 95%CI: 1.449-1.556), and average geographic accessibility of healthcare services (OR=1.073, 95%CI:1.017-1.129) were risk factors for health-care seeking delay, and the risk was relatively lower in the migrating population (OR=0.920, 95%CI: 0.815-0.989). Conclusion　The rate of delayed health-care seeking for tuberculosis patients in Changsha City in 2019-2023 is at a moderate level in the surrounding areas, and the overall trend is increasing. It suggests that proactive screening strategies for key populations should be optimized to improve the accessibility of healthcare services and reduce the rate of health-care seeking delay.

OBJECTIVE: To observe the effects of acupoint catgut embedding (ACE) on gut microbiota and fecal short-chain fatty acids (SCFAs) levels in patients with Parkinson's disease (PD) with constipation. METHODS: A total of 80 PD patients with constipation were randomly divided into an observation group and a control group, 40 cases in each group. Additionally, 40 healthy individuals were recruited as a healthy control group. The control group received conventional Western medical treatment for PD combined with polyethylene glycol (PEG), once daily for eight weeks. The observation group received additional ACE treatment at bilateral Tianshu (ST25), Zusanli (ST36), and Shangjuxu (ST37), once every two weeks for eight weeks. The healthy control group received no intervention. The spontaneous bowel movements (SBMs) per week and patient assessment of constipation quality of life (PAC-QOL) scores were assessed at baseline and after treatment in the two groups. Fecal samples were collected at the end of treatment for the observation and the control groups and at baseline for the healthy control group. Gut microbiota composition and diversity were analyzed using 16S rRNA method, and SCFA levels were measured using high-performance liquid chromatography (HPLC). RESULTS: Compared before treatment, the observation group showed a significant increase in SBMs (P<0.01), and PAC-QOL scores including physical discomfort, psychosocial discomfort, worry and concern, and total score were significantly reduced (P<0.01) after treatment; the control group also showed a reduction in PAC-QOL total score after treatment (P<0.01). After treatment, the observation group had significantly more SBMs (P<0.01), and lower PAC-QOL physical discomfort, psychosocial discomfort, worry and concern scores, and total score (P<0.01), and higher PAC-QOL satisfaction score (P<0.01) than the control group. Compared with the healthy control group, the control group showed decreased Chao1 and Ace indices (P<0.01). Compared with the healthy control group, the relative abundance of Prevotella and Roseburia was increased (P<0.05), while that of Enterobacter and Ruminococcus torques (six species in total) was decreased (P<0.05) in the control group. Compared with the control group, the observation group had increased relative abundance of Dialister, Parabacteroides, and Ruminococcus torques (P<0.05), and decreased relative abundance of Prevotella and Eubacterium ruminantium (P<0.05). Compared with the healthy control group, the control group had increased fecal SCFA levels (P<0.05); compared with the control group, the observation group had reduced fecal SCFA levels (P<0.05). Compared with the healthy control group, acetic acid, propionic acid, and butyric acid levels were elevated in the control group (P<0.05); compared with the control group, acetic acid, propionic acid, and butyric acid levels were decreased in the observation group (P<0.05). CONCLUSION ACE could increase spontaneous bowel movements and improve the quality of life in PD patients with constipation, which may be related to the regulation of gut microbiota composition and SCFA levels.
