Chronic atrophic gastritis(CAG)is a chronic gastric disorder characterized by recurrent damage to the gastric mucosal epithelium,resulting in the reduction of intrinsic glands,with or without concurrent intestinal metaplasia.The"hyperactive stomach qi"theory,derived from Huang Di Nei Jing Su Wen Ji Zhu,proposes that the core pathogenesis of CAG lies in excessive stomach qi activity,grounded in the physiological principle of"strong yang qi in earth and weak yin qi in earth".This theory synthesizes the clinical manifestations and pathological progression of CAG,asserting that its development often involves intertwined pathological factors such as stagnation,dryness-heat,phlegm-dampness and stasis-toxicity.A triphasic therapeutic framework is proposed:the spleen qi deficiency phase,marked by impaired spleen transport function and dysregulated qi-fluid distribution,requiring spleen fortification and qi-fluid regulation;the hyperactive stomach qi phase,characterized by intensified stomach qi activity coupled with dryness-damp stagnation,necessitating stagnation resolution,dampness elimination and yin nourishment;the decline and disorder of middle qi phase,characterized by the deficiency of the middle qi,with phlegm,blood stasis and toxins forming the terminal stage.Treatment should focus on reinforcing the middle and restoring balance,detoxifying and dissipating accumulation.By exploring CAG pathogenesis and treatment through the lens of"hyperactive stomach qi",this study aimed to provide novel theoretical insights and therapeutic strategies for TCM in the prevention and treatment of CAG.

Objective:To establish a standardized code database of adverse drug reactions (ADRs) terms related to linezolid and analyze the common ADRs of linezolid.Methods:Linezolid drug labels, websites (including Side Effect Resource, and the official websites of US Food and Drug Administration, European Medicines Agency and National Medical Products Administration) and scientific literature database (including CNKI, Wanfang, VIP, PubMed, Embase and Web of Science databases) were systematically searched, and ADR terms about linezolid were collected. ADR terms were mapped to the international classification of diseases-10 (ICD-10) code to establish a linezolid adverse reaction database.Results:A total of 117 ADR terms about linezolid were collected and 91 ICD-10 codes were obtained after being mapped to ICD-10. A standardized database was constructed and successfully embedded into the ADR spontaneous reporting system as a specific drug submodule. The gastrointestinal system, skin and subcutaneous tissue system, various nervous systems, blood and lymphatic systems were the most common system organs involved in linezolid-related ADRs under the 91 ICD-10 codes. Among them, ADRs under the gastrointestinal system codes K14.302 (black hairy tongue) and K52.104 (drug-induced gastroenteritis and colitis), the skin and subcutaneous tissue system code L27.005 (drug-induced dermatitis), various nervous system codes G90.800 (other disorders of autonomic nervous system), G62.001 (drug-induced polyneuropathy) and G44.400 (drug-induced headache, not elsewhere classified), the blood and lymphatic system codes D69.502 (drug- induced thrombocytopenia) and D70.x02 (drug-induced granulocytopenia), the metabolic and nutritional codes E87.204 (lactic acidosis), as well as the endocrine system code E16.000 (drug-induced hypoglycaemia without coma) had been reported frequently in the scientific literature. In addition, there were 14 ADR terms related to linezolid under 13 ICD-10 codes not recorded in the drug instructions.Conclusions:It is feasible to use ICD-10 code to standardize ADR terms related to linezolid and establish a database. Common ADRs of linezolid include thrombocytopenia, lactic acidosis, neutropenia, black hairy tongue, gastroenteritis/colitis, hypoglycemia, rash, serotonin syndrome, peripheral neuropathy and headache, which should be paid attention to and researched furtherly.

BACKGROUND:Currently,artificial corneas used for full-thickness transplantation lack biological activity and mechanical adaptability.Composite artificial corneas face interface issues between the corneal button and surrounding components.OBJECTIVE:To prepare an integrated artificial cornea with peptide enhancement,matched mechanical strength to natural cornea,and excellent transparency via in situ ultraviolet light curing of decellularized porcine cornea.METHODS:Non-ionic decellularization reagent Triton X-100 combined with ultrasonic freeze-thawing and super nucleases was utilized to prepare decellularized porcine cornea.Hydroxyethyl methacrylate monomer and photoinitiator were introduced into the decellularized porcine cornea simultaneously.Ultraviolet light with a filter was used to cover the peripheral region except for the central area,where polymerization was initiated using 275 nm ultraviolet light.After removal of unreacted monomers and initiators,the central optical zone was obtained.Similarly,the posterior lamellar layer was polymerized to form the hydrophobic barrier zone.Finally,REG active polypeptide was introduced to obtain in situ integrated full-layer artificial cornea.The physical properties,mechanical properties,transparency,degradation properties and in vivo and in vitro biocompatibility of artificial cornea were characterized.RESULTS AND CONCLUSION:(1)An optical region with the co-existence of polymer and collagen fibers was constructed in situ using hydroxyethyl methacrylate in the central region of decellularized porcine cornea.Under scanning electron microscopy,the upper surface of the artificial cornea was rough and irregular,with obvious concave and convex structure,and the lower surface was relatively smooth.The artificial cornea had mechanical properties close to those of natural cornea.The transparency of the optical zone reached 80%of that of the natural cornea.After soaking in PBS aseptic solution containing collagenase,it could preserve the solidified optical region and hydrophobic barrier zone,and maintain the basic structure of cornea.The artificial cornea had good cytocompatibility,could provide a suitable adhesion and growth environment for cells,was conducive to the migration and adhesion of corneal epithelial cells,promoted the growth of vascular endothelial cells and the formation of new blood vessels,and promoted the epithelialization process.The artificial cornea had good biocompatibility and safety after 12 weeks of subcutaneous implantation in SD rats,and could reduce the acute inflammatory reaction at the initial stage of implantation.(2)The results show that the integrated full-layer artificial cornea prepared by the experiment has the potential as a full-layer artificial cornea scaffold.

Objective:To investigate the effect of innovative perioperative pain management on prostate cancer patients with he-maturia undergoing prostatic artery embolization(PAE).Methods:A total of 60 patients undergoing PAE in the Interventional Ther-apy Department of General Hospital of Eastern Theater Command from May 2024 to January 2025 were selected by convenience sam-pling method and randomly divided into the intervention group and the control group,with 30 patients in each group.The control group received traditional pain management of nursing.An innovative perioperative pain management was performed in intervention group in-cluding preoperative"body-mind-pain"holistic assessment and preparation,intraoperative humanistic care and real-time support,post-operative multimodal analgesia and rehabilitation,dynamic monitoring and closed-loop feedback.The pain degree after 6 hours,1 day,3 days and 1 week of the operation,and the quality of life after 1 week of operation,as well as nursing satisfaction at discharge were compared between the two groups.Results:The VAS scores of the intervention group were significantly lower than those of the con-trol group after 6 hours,1 day,3 days and 1 week of operation(P＜0.05).One week after the operation,the quality of life in the ob-servation group was higher than that of the control group significantly(P＜0.05).The nursing satisfaction of the observation group was significantly higher than that of the control group at discharge(P＜0.05).Conclusion:The application of innovative perioperative pain management can alleviate pain of patients with PAE,which improves the quality of life and nursing satisfaction of patients,and is conducive to the rehabilitation of patients.

Cerebral proliferative angiopathy(CPA)was initially regarded as a variant of arteriovenous malformation.However,its distinct histological,angiographic,and pathophysiological features have led to its reclassification as an independent entity.CPA is an exceptionally rare form of cerebral vascular malformation,its pathogenesis is primarily linked to diffuse vascular proliferation secondary to chronic hypoperfusion.Clinically,CPA presents with a heterogeneous spectrum of manifestations,most commonly severe headaches and epileptic seizures.Neuroimaging(MR)typically reveals a complex interplay of aberrant vessels within the brain parenchyma,which may complicate the clinical management and lead to a higher rate of poor prognosis.This article reviewed current knowledge on the pathogenesis,epidemiology,clinical features,diagnostic approaches,and treatment options for CPA,with the aim of enhancing understanding of its underlying mechanisms and guiding future therapeutic strategy optimizations.

OBJECTIVE To explore the effect of fluconazole on proteomics of Trichosporon asahii so as to reveal the responding process of T.asahii to fluconazole stress and the resistance mechanisms to azoles on the protein level.METHODS T.asahii AS 2.2174 was chosen as the research subject,the minimum inhibitory concentration(MIC)of fluconazole was determined by broth microdilution assay.The protein abundance of T.asahii was detec-ted by means of tandem mass tag(TMT)technique combined with liquid chromatography-tandem mass spectrom-etry(LC-MS/MS)before and after the treatment with fluconazole(1× MIC).The differentially expressed pro-teins(DEPs)were identified based on the screening standards of fold change ≥1.20 or ≤0.83 and P＜0.05.Gene ontlogy(GO)and Kyoto encyclopedia of genes and genomes(KEGG)enrichment analysis were performed for the DEPs so as to understand the biological property of the DEPs and the major biological pathways that the DEPs in-volved in.Finally,the targeted validation was carried out for the targeted differentially expressed proteins by using multiple reaction monitoring(MRM).RESULTS The MIC of fluconazole to T.asahii AS 2.2174 was 8 μg/ml.Totally 196 DEPs were identified,including 93 upregulated DEPs and 103 downregulated DEPs.The function en-richment analysis showed that the DEPs mainly participated in synthesis and metabolism of sterols,drug metabo-lism,stress response,energy metabolism and intertranslation.The targeted DEPs showed the consistent expres-sion trends in MRM target validation and TMT-LC-MS/MS.CONCLUSIONS The protein abundance of T.asahii has remarkable change under the fluconazole stress.The bioinformatics analysis reveals the complicated molecular mechanisms of T.asahii in response to the fluconazole stress,which may offer valuable ideas for understanding the drug resistance to azoles and developing new drug targets.

Objective : To explore the expression profile of core 1 β1,3-galactosyltransferase 1(C1GALT1) in glioblastoma(GBM) and to elucidate its impact on the initiation and progression of GBM. Methods : The expression levels and prognostic significance of C1GALT1 in GBM were analyzed using the GEPIA and CGGA databases. Two representative glioblastoma cells(U251 and LN18) were selected to construct C1GALT1-knockdown cell lines and performed in vitro experiments. The Cell Counting Kit-8(CCK-8) and Transwell assays were employed to evaluate the impact of C1GALT1 on proliferation, migration and invasion of GBM cells. Transcriptome data were analyzed to identify potential signaling pathways. Senescence β-Galactosidase Staining Kit was used to detect β-galactosidase activity. Results : nalysis of GEPIA and CGGA databases revealed that C1GALT1 was significantly upregulated in GBM tissues compared to adjacent non-cancerous tissues (P < 0. 05) , and its high expression was associated with poor prognosis of patients (P < 0. 000 1) . The CCK-8 experiment demonstrated a significant reduction in prolifera- tion rate following C1GALT1 knockdown (P < 0. 05) . Transwell assay showed that cell migration and invasion de- creased after C1GALT1 was knocked down ( P < 0. 001) . Transcriptome sequencing and senescence β-galactosi- dase staining showed that C1GALT1 was involved in the cellular senescence signaling pathway , and the activity of β-galactosidase associated with cellular senescence significantly increased after C1GALT1 was knocked down(P < 0. 05) . Conclusion C1GALT1 is overexpressed in GBM tissues and may promote the proliferation , migration and invasion of GBM cells by inhibiting cellular senescence .

Objective To analyze the incidence and mortality of gastric cancer in countries and territories with different human development index(HDI)levels in 2022,and to understand the burden of gastric cancer globally and in China.Methods Data on gastric cancer incidence and mortality were collected from GLOBOCAN 2022 and HDI data for all countries were obtained from the Human development report 2022.Spearman correlation was applied to examine the associations between the age-standardized incidence rate(ASIR),age-standardized mortality rate(ASMR),mortality-to-incidence ratio(M/I),and HDI for gastric cancer.The Wilcoxon rank-sum test was used to assess the differences in ASIR and ASMR between males and females.Results In 2022,gastric cancer ranked the 5th in both incidence and mortality among all cancer types globally.In China,gastric cancer ranked the 5th in incidence and the 3rd in mortality among all cancer types.The ASIR and ASMR of gastric cancer showed a descending trend from high,very high,medium to low HDI countries and territories.The ASIR of gastric cancer was positively correlated with HDI(rs=0.256,P=0.001),while ASMR showed no significant correlation with HDI(rs=-0.008,P=0.918).The M/I was negatively correlated with HDI(rs=-0.831,P＜0.001).The ASIR and ASMR of gastric cancer in males were significantly higher than those in females globally,in China,and across all HDI groups(all P＜0.05).Globally,both ASIR and ASMR of gastric cancer remained relatively stable before the age of 45,but showed a consistently rising trend after the age of 45.In China,the ASIR and ASMR of gastric cancer exceeded global average level across all age groups.Conclusion The burden of gastric cancer incidence and mortality is higher in very high and high HDI countries and territories compared to medium and low HDI countries and territories.In China,the burden of gastric cancer incidence and mortality is above the global average,highlighting the need for targeted prevention and control measures.
