		                        			ObjectiveTo reveal the mechanism of Zuogui Jiangtang Jieyu prescription against damage to hippocampal synaptic microenvironment via suppressing glutamate receptor 2 (GluR2)/Parkin signal-mediated mitophagy in rats with diabetes-related depression (DD). MethodsEighty male SD rats underwent adaptive feeding for 5 days before the study. Ten rats were randomly assigned to the normal group. The model of DD rats was established with the rest by 2-week high-fat diet + streptozotocin (STZ) tail intravenous injection + 28 days of chronic unpredictable mild stress (CUMS) combined with isolation. The rats were randomly divided into a normal group, a model group, a GluR2 blocker group (5 μg·kg-1), a GluR2 agonist group (10 μg·kg-1), a metformin + fluoxetine group (0.18 g·kg-1 metformin + 1.8 mg·kg-1 fluoxetine), and high- and low-dose Zuogui Jiangtang Jieyu prescription groups (20.52 and 10.26 g·kg-1, respectively). The rats in the GluR2 blocker group and the GluR2 agonist group were continuously injected with CNQX and Cl-HIBO in the dentate gyrus of the hippocampus once a week starting from stress modeling, respectively, while the metformin + fluoxetine group and the high- and low-dose Zuogui Jiangtang Jieyu prescription groups were continuously given intragastric administration for 28 d at the same time of stress modeling. Depression-like behavior was evaluated by open field and forced swimming experiments. The levels of serum insulin and adenosine triphosphate (ATP) in hippocampus were detected by biochemical analysis. The levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in hippocampus were detected by enzyme-linked immunosorbent assay (ELISA). The autophagosomes of hippocampal neurons were observed by transmission electron microscopy. The morphology and structure of dendrites and spines of hippocampal neurons were evaluated by Golgi staining. Western blot detected the expression levels of GluR2 and Parkin proteins in hippocampus. The expression levels of GluR2, Parkin, regulating synaptic membrane exocytosis protein 3 (RIMS3), and postsynaptic density protein 95 (PSD95) in the dentate gyrus of the hippocampus were detected by immunofluorescence. ResultsCompared with the normal group, the model group exhibited reduced total activity distance in the open field and increased immobility time in forced swimming (P<0.01), lowered levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.01), increased autophagosomes of hippocampal neurons, significantly damaged morphology and structure of dendrites and spines of hippocampal neurons, decreased expression levels of GluR2, RIMS3, and PSD95 in hippocampus, and an increased Parkin expression level (P<0.05, P<0.01). Compared with the model group, the GluR2 blocker group and the GluR2 agonist group showed aggravation and alleviation of the above abnormal changes, respectively (P<0.05, P<0.01). The above depression-like behavior was significantly improved in the high- and low-dose Zuogui Jiangtang Jieyu prescription groups to different degrees. Specifically, the two groups saw elevated levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.05, P<0.01), restrained increase in autophagosomes and damage to morphology and structure of dendrites and spines of hippocampal neurons, up-regulated protein expression levels of GluR2, RIMS3, and PSD95, and down-regulated Parkin expression level (P<0.05, P<0.01). ConclusionZuogui Jiangtong Jieyu prescription can ameliorate the mitophagy-mediated damage to hippocampal synaptic microenvironment in DD rats, the mechanism of which might be related to the regulation of GluR2/Parkin signaling pathway.

		                        			 AIM: To analyze the clinical outcomes of cyclosporine combined with lacrimal plug in the treatment of dry eye in patients with primary Sjögren's syndrome.METHODS: The clinical data of 60 patients(120 eyes)who were admitted to the ophthalmology department and rheumatology and immunology department of Baoding No.1 Central Hospital and were diagonosed with siogren's syndrome dry eye after multidisciplinary consultation from June 2022 to September 2023 were retrospectively analyzed. All the patients received regular treatment of primary Sjögren's syndrome, and they were divided into three groups according to treatment methods: A, B and C, with 20 cases(40 eyes)in each group. The group A received 0.3% sodium hyaluronate eyedrops, the group B received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops, and the group C received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops combined with binocular lacrimal plugs. The ocular surface disease index(OSDI)score, conjunctival hyperemia score, tear film breakup time(BUT), tear meniscus height(TMH), corneal fluorescein staining(FL)score and tear secretion of the three groups of patients were compared before and at 4, 8 and 12 wk after treatment. The contents of inflammatory factors such as interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)in tears were detected before and at 12 wk after treatment.RESULTS: At 4, 8 and 12 wk after treatment, the scores of OSDI, conjunctival hyperemia score and FL in the three groups of patients were lower than those before treatment, and the BUT, TMH and tear secretion were higher than those before treatment(all P<0.001). The OSDI score of the group C was lower than that of the group A and B, and the group B was lower than the group A(all P<0.001). The BUT, TMH and tear secretion of the group C were higher than those of the group A and B, with the group B higher than the group A(all P<0.001). At 12 wk after treatment, the levels of IL-6, TNF-α and IL-1β in the tears of the three groups of patients were lower than those before treatment, with the group C lower than the group A and B, and the group B lower than the group A(all P<0.001). There was no statistical significant difference in the incidence of adverse reactions among the three groups of patients(P>0.05).CONCLUSION: The combined use of cyclosporine and lacrimal plug is safe and effective in improving the clinical symptoms of patients with moderate and severe dry eye, promoting the function of tear film and cornea, increasing tears secretion, and reducing the level of tear inflammatory factors.

		                        			Exercise-induced metabolic remodeling is a fundamental adaptive process whereby the body reorganizes systemic and cellular metabolism to meet the dynamic energy demands posed by physical activity. Emerging evidence reveals that such remodeling not only enhances energy homeostasis but also profoundly influences immune function through complex molecular interactions involving glucose, lipid, and protein metabolism. This review presents an in-depth synthesis of recent advances, elucidating how exercise modulates immune regulation via metabolic reprogramming, highlighting key molecular mechanisms, immune-metabolic signaling axes, and the authors’ academic perspective on the integrated “exercise-metabolism-immunity” network. In the domain of glucose metabolism, regular exercise improves insulin sensitivity and reduces hyperglycemia, thereby attenuating glucose toxicity-induced immune dysfunction. It suppresses the formation of advanced glycation end-products (AGEs) and interrupts the AGEs-RAGE-inflammation positive feedback loop in innate and adaptive immune cells. Importantly, exercise-induced lactate, traditionally viewed as a metabolic byproduct, is now recognized as an active immunomodulatory molecule. At high concentrations, lactate can suppress immune function through pH-mediated effects and GPR81 receptor activation. At physiological levels, it supports regulatory T cell survival, promotes macrophage M2 polarization, and modulates gene expression via histone lactylation. Additionally, key metabolic regulators such as AMPK and mTOR coordinate immune cell energy balance and phenotype; exercise activates the AMPK-mTOR axis to favor anti-inflammatory immune cell profiles. Simultaneously, hypoxia-inducible factor-1α (HIF-1α) is transiently activated during exercise, driving glycolytic reprogramming in T cells and macrophages, and shaping the immune landscape. In lipid metabolism, exercise alleviates adipose tissue inflammation by reducing fat mass and reshaping the immune microenvironment. It promotes the polarization of adipose tissue macrophages from a pro-inflammatory M1 phenotype to an anti-inflammatory M2 phenotype. Moreover, exercise alters the secretion profile of adipokines—raising adiponectin levels while reducing leptin and resistin—thereby influencing systemic immune balance. At the circulatory level, exercise improves lipid profiles by lowering pro-inflammatory free fatty acids (particularly saturated fatty acids) and triglycerides, while enhancing high-density lipoprotein (HDL) function, which has immunoregulatory properties such as endotoxin neutralization and macrophage cholesterol efflux. Regarding protein metabolism, exercise triggers the expression of heat shock proteins (HSPs) that act as intracellular chaperones and extracellular immune signals. Exercise also promotes the secretion of myokines (e.g., IL-6, IL-15, irisin, FGF21) from skeletal muscle, which modulate immune responses, facilitate T cell and macrophage function, and support immunological memory. Furthermore, exercise reshapes amino acid metabolism, particularly of glutamine, arginine, and branched-chain amino acids (BCAAs), thereby influencing immune cell proliferation, biosynthesis, and signaling. Leucine-mTORC1 signaling plays a key role in T cell fate, while arginine metabolism governs macrophage polarization and T cell activation. In summary, this review underscores the complex, bidirectional relationship between exercise and immune function, orchestrated through metabolic remodeling. Future research should focus on causative links among specific metabolites, signaling pathways, and immune phenotypes, as well as explore the epigenetic consequences of exercise-induced metabolic shifts. This integrated perspective advances understanding of exercise as a non-pharmacological intervention for immune regulation and offers theoretical foundations for individualized exercise prescriptions in health and disease contexts.

		                        			ObjectiveTo explore the effects of astragalin (AST) on autophagy and apoptosis of astrocytes in the L4-5 dorsal horn of the spinal cord in mice with inflammatory pain induced by complete Freund's adjuvant (CFA). MethodsTwenty-four male C57BL/6 mice, aged six months, were randomly assigned to four groups: control group, saline group, CFA model group, and CFA+AST group, six mice in each group. The inflammatory pain model was established by injection of 10 µL CFA into the right lateral malleolus fossa. The saline group were injected with an equal amount of normal saline at the same site. The inflammatory pain mice in CFA+AST group were further treated with AST (60 mg/kg) intraperitoneally once a day for 21 consecutive days. Multiplex immunofluorescence staining was used to detect the coexpression of autophagy-related factors including ATG 12 and Beclin-1, apoptosis-related factors including Cleaved-Caspase3 and Caspase9, and the astrocyte marker such as GFAP in the L4-5 spinal dorsal horn of the mice in each group. Western blot was used to examine the protein expression levels of autophagy-related proteins(ATG12, Beclin-1) and apoptosis-related proteins(Caspase 3, Caspase 9) in the L4-5 spinal dorsal horn of mice. ResultsImmunofluorescent staining showed that in the L4-5 dorsal horn of the spinal cord, the fluorescence intensity of ATG12 (P<0.000 1) and Beclin-1 (P<0.000 1) was significantly increased, while that of Cleaved-Caspase 3 (P<0.001) and Caspase 9 (P<0.000 1) was decreased in the CFA+AST group when compared to the CFA model group. Furthermore, AST could inhibit the activation of astrocytes. Western blot further confirmed that AST significantly upregulated the expression of ATG12 (P<0.000 1) and Beclin-1 (P<0.000 1) in the L4-5 spinal cord of CFA mice, and downregulated the expression of Caspase 3 (P<0.01) and Caspase 9 (P<0.001). ConclusionsAST promotes autophagy of astrocytes and inhibits their apoptosis in the L4-5 spinal dorsal horn of CFA mice.

		                        			Objective To evaluate the safety and efficacy of simultaneous resection for initially resectable rectal cancer with synchronous liver metastases. Methods A retrospective analysis was conducted on 305 patients with initially resectable rectal cancer with synchronous liver metastases. These patients were diagnosed at Zhongshan Hospital, Fudan University from January 2016 to June 2020. Among them, 191 underwent simultaneous rectum and liver resection and 114 underwent staged resection. Propensity score matching (PSM) was performed at a 1∶1 ratio. Clinical data were compared and Kaplan-Meier survival curves were plotted. Results After PSM, 85 patients were included in each group. General data showed no significant differences. Except for liver metastasis resection method, no statistical differences were found in primary tumor surgery approach, intraoperative blood loss, intraoperative complications, time to first flatus and defecation, 30-day mortality, and postoperative hospital stay between the simultaneous resection group and the staged resection group. The overall complication rate was higher in the simultaneous resection group (48.2% vs 29.4%, P=0.04). Specifically, the grade Ⅱ complications were significantly higher (29.4% vs 14.1%, P=0.016), but there’s no differences in severe complications (grade Ⅲ-Ⅴ). No statistically differences were observed in median progression-free survival (HR=0.70, 95%CI 0.50-0.97, P=0.103) and 5-year overall survival (HR=0.95, 95%CI 0.63-1.44, P=0.259). Conclusions Simultaneous resection demonstrates comparable safety and efficacy to staged resection for initially resectable rectal cancer with synchronous liver metastases.

		                        			ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions, so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values(L*) of the surface, cross-section and powder of the samples, texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography(HPLC) was used to determine the contents of seven nucleoside components(uracil, hypoxanthine, uridine, inosine, guanosine, β-thymidine and adenosine) in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis(PCA) was used to comprehensively rank the data of various indicators, and partial least squares-discriminant analysis(PLS-DA) was used to screen differential components with variable importance in the projection(VIP) value>1. Furthermore, the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature, the color of the intermittently dried samples gradually deepened, while their hardness gradually decreased. Concurrently, the contents of extract, total starch, uridine and adenosine exhibited an upward trend, whereas the contents of uracil, hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group, the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose, the hardness and the total content of nucleoside components in the samples showed a downward trend, while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L* was negatively correlated with the contents of uracil, hypoxanthine and inosine, and positively correlated with the contents of uridine, guanosine and adenosine. Hardness was negatively correlated with adenosine content, and positively correlated with the contents of inosine, uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components, the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract, the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition, while uridine, uracil, guanosine, adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination, which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

		                        			In this work, starting from 4-hydroxycoumarin, three series of 22 coumarin derivatives, among which 8 have not been reported in the literature, were synthesized and their in vitro anti-inflammatory activities and mechanisms of action were preliminarily investigated using mouse macrophage model. The results showed that most of the derivatives could significantly inhibit the production of pro-inflammatory factor NO, with compounds 2e, 2f, 2g, 2h, 2i, 2j, 4e, and 4f showing better anti-inflammatory activity than the positive control drug dexamethasone. Further experiments showed that compounds 2h and 4f significantly inhibited the production of pro-inflammatory factors IL-6, TNF-α and IL-1β in RAW264.7 macrophages, and could, therefore, be used as lead compounds for further studies.

Methods We reviewed the clinical data of 11 patients with anti-LGI1 encephalitis hospitalized in Fu Yang People's Hospital from October 2019 to December 2024. Results All the 11 patients(100%)had cognitive function involvement,9(81.8%)had epileptic seizures,5(45.5%)had mental and behavioral abnormalities,4(36.4%)had sleep disorders,3(27.3%)had autonomic nervous dysfunction,2(18.2%)had faciobrachial dystonic seizures(FBDS),2(18.2%)had facial numbness,and 1(9.1%)had phantosmia and pruritus in both eyes and the neck. LGI1 antibody was positive in the serum of all the cases(100%)and present in the cerebrospinal fluid of 8 cases(72.3%). Seven cases(63.6%)had hyponatremia,and 5 cases(45.5%)also had hypophosphatemia,hypocalcemia,and hypomagnesemia in addition to blood sodium lower than 134 mmol/L. Intracranial abnormalities were detected in 7 cases(63.6%)on magnetic resonance imaging. Electroencephalogram abnormalities were recorded in 6 cases(54.5%). After immunosuppressive treatment,2 cases(18.2%)had recurrent symptoms,and 2 cases(18.2%)had residual mild memory impairment. In terms of prognosis,the modified Rankin Scale scores were generally favorable. Conclusion Anti-LGI1 encephalitis manifests as convulsions,FBDS,memory decline,mental and behavioral abnormalities,autonomic nervous dysfunction,sleep disorders,hyponatremia,and multiple electrolyte disorders such as hypomagnesemia,hypocalcemia,and hypophosphatemia when blood sodium is below 134 mmol/L. The prognosis with immunosuppressive treatment is favorable,but recurrent symptoms may occur.

		                        			Objective: To report the clinical data of two patients with prostatic hyperplasia and bladder uric acid stones,so as to provide reference for clinical practice. Methods: Clinical data of two patients successfully undergoing blue laser lithotripsy in Department of Urology,Zhenba County People's Hospital were retrospectively analyzed,including clinical manifestations,surgical methods,treatment outcomes and complications. Results: Both patients sought medical care due to progressive dysuria or hematuria.B ultrasound and magnetic resonance imaging confirmed bladder calculi and prostatic hyperplasia.One patient also had large blood clots in the bladder cavity.Both patients received transurethral blue laser prostate vaporization + transurethral bladder stone holmium laser lithotripsy.The stone surface was dark yellow,with no obvious pores,fine particles or spike protrusion.Blue laser produced an “ablative” phenomenon similar to vaporization,and then stones became smaller and fragmented.The lithotripsy lasted for 11 min and 8 min,respectively.There were multiple bladder mucosal injuries due to constant drift of stones during operation.Stone composition analysis suggested uric acid stones.After 3 months of follow-up,both patients had smooth postoperative urination,good urine control,and no stone recurrence. Conclusion: Blue laser can be applied to crush uric acid stones,and the bladder mucosa should be protected during lithotripsy.
