Objective To explore the correlations of serum heat shock protein 70(Hsp70),high-mobility group box 1(HMGB1),glial fibrillary acidic protein(GFAP),and cognitive impair-ment(CI)in patients with cerebral small vessel disease(CSVD).Methods A total of 117 patients with CSVD who were treated at Kailuan General Hospital from July 2023 to July 2024 were selected as study subjects(CSVD group).According to varied scores of the Mini-Mental State Examination(MMSE),they were divided into CI group(54 cases)and non-CI group(63 cases).Additionally,120 healthy individuals who underwent health check-ups during the same period were selected as con-trol group.Clinical data of all subjects were collected.Enzyme-linked immunosorbent assay(ELISA)was used to detect the expression levels of Hsp70,HMGB1,and GFAP in serum.The Spearman method was employed to analyze the correlations of serum Hsp70,HMGB1,and GFAP levels with the occurrence of CI in CSVD patients.Logistic multivariate regression analysis was conducted to screen for influencing factors of CI in CSVD patients.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of serum Hsp70,HMGB1,and GFAP levels for CI in CSVD patients.Results The serum levels of Hsp70,HMGB1,and GFAP in the CSVD group were higher than those in the control group(P＜0.05).There were no significant differences in gender,age,body mass index,smoking history,drinking history,nature of CSVD,education level,triglyc-erides(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),Trail Making Test-A(TMT-A),Trail Making Test-B(TMT-B),and low-density lipoprotein cholesterol(LDL-C)between the CI group and the non-CI group(P＞0.05).The levels of uric acid(UA),serum Hsp70,HMGB1,and GFAP in the CI group were higher than those in the non-CI group,while the Montreal Cognitive Assessment(MOCA)score was lower than that in the non-CI group(P＜0.05).The serum levels of Hsp70,HMGB1,and GFAP in CSVD patients were negatively correla-ted with MMSE scores(r=-0.458,-0.525,-0.431,P＜0.05)and MOCA scores(r=-0.462,-0.583,-0.484,P＜0.05).Logistic regression analysis showed that Hsp70,HMGB1,and GFAP were influencing factors for CI in CSVD patients(P＜0.05).The areas under the curve(AUC)for serum Hsp70,HMGB1,and GFAP levels and their combined prediction of cognitive function in CSVD patients were 0.734,0.769,0.766,and 0.902,respectively.The predictive ef-ficacy of the combined prediction was better than that of individual indicators(P＜0.05).Conclu-sion The serum levels of Hsp70,HMGB1,and GFAP are elevated in CSVD patients,which are closely related to the occurrence of CI.The combined detection of these three proteins has a high predictive value for CI in CSVD patients.

AKT,also known as Protein Kinase B(PKB),plays a critical role in cell proliferation and metabolism.There are three isoforms of AKT:AKT1,AKT2,and AKT3.The effects of these isoforms on the pluripotency and differentiation of mouse embryonic stem cells(mESCs)remain unclear.This study aims to explore the impact of three AKT isoform-specific knockouts on the self-renewal and differen-tiation of mouse embryonic stem cells.Using CRISPR/Cas9 gene-editing technology,AKT isoform-spe-cific knockout cell lines were established.The phenotypic and molecular changes were analyzed through Western blotting,flow cytometry,qRT-PCR,CCK-8 assays,Alkaline Phosphatase(AP)staining,and RNA-seq.The construction of AKT isoform-specific knockout cell lines was successful.The loss of AKT1 and AKT2 inhibited the proliferation of mESCs.The knockout of any single AKT isoform did not affect the expression of pluripotency genes at both mRNA or protein levels.However,during embryoid body forma-tion,the deletion of any of the three AKT isoforms affected the mRNA expression levels of genes in all three germ layers.Transcriptome analysis showed that compared to wild-type mESCs,995,547,and 429 differentially expressed genes(|log2FC|≧1,P＜0.05)were identified inAKT1,AKT2,and AKT3 isoform-specific knockout cells,respectively.There was some overlap in the differentially expressed genes regulated by these three isoforms.In conclusion,the independent knockout of AKT isoforms does not af-fect the maintenance of pluripotency in mouse embryonic stem cells,but they are crucial for differentia-tion.The three AKT isoforms can collectively regulate gene expression while retaining their own regulato-ry specificity.This study provides a foundation for understanding the unique and overlapping roles of AKT isoforms in stem cell biology,highlighting their importance in maintaining stem cell function and differen-tiation.

Objective To compare the efficacy and safety of gemcitabine combined with conventional-dose cisplatin(70 mg/m2,day 2)versus split-dose cisplatin(35 mg/m2,days 1 and 8)in neo-adjuvant therapy for muscle-invasive bladder cancer(MIBC).Methods The clinical data of 33 MIBC patients receiving(gemcitabine+cisplatin,GC)-based neoadjuvant chemotherapy in the Department of Urology of Xinhua Hospital,during Jan.2021 and Aug.2024 were retrospectively analyzed,including 18(54.5％)patients treated with a conventional-dose regimen(GC group),and 15(45.5％)patients treated with a split-dose regimen(GCs group).The efficacy endpoints and incidence/severity of adverse reactions were compared between the two groups.Results Baseline characteristics were well-balanced between the two groups(P＞0.05).No significant differences were observed in the complete response rate(CR:33.3％vs.22.2％),objective response rate(ORR:66.7％vs.61.1％),or disease control rate(DCR:80.0％vs.88.9％)between the GCs and GC groups(P＞0.05).The GCs group exhibited a significantly lower incidence of chemotherapy-related renal injury(6.7％vs.38.9％,P＜0.05),while the occurrence of other adverse events was comparable between the two groups.Notably,the GCs group demonstrated significantly attenuated nephrotoxicity,as evidenced by markedly smaller changes in estimated glomerular filtration rate[eGFR:(4.5±4.7)％vs.(18.0±11.8)％]and serum creatinine[SCr:(5.7±5.6)％vs.(20.2±19.5)％]compared to the GC group(P＜0.05).Conclusion Compared with the conventional-dose regimen,the split-dose regimen maintains equivalent clinical efficacy of GC-based neoadjuvant chemotherapy while significantly reducing chemotherapy-related nephrotoxicity,thereby providing MIBC patients with a safer therapeutic option.

Objective:This study aims to investigate the differences in emotional status and cognitive function among patients with vestibular migraine (VM), Meniere′s disease (MD), and their comorbidity (VMMD), and to analyze key factors influencing cognitive function.Methods:This cross-sectional study included 96 outpatients (32 males, 64 females, aged 21-73 years) from the Department of Otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, between December 2022 and December 2023. The study population consisted of 31 VM patients (VM group), 36 MD patients (MD group), and 29 VMMD patients (VMMD group), along with 32 healthy controls (16 males, 16 females, aged 19-74 years). Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), while emotional status and somatization symptoms were evaluated through the Generalized Anxiety Disorder scale, Patient Health Questionnaire Depression scale, Symptom Checklist-90, and the Self-rating Somatization Symptom scale. Multiple linear regression analysis was conducted to explore the influence of different variables on cognitive function.Results:The total MoCA score in the VMMD group (26.0 [24.5, 28.0]) was significantly lower than that in the control group (28.0 [27.0, 29.0]) and the MD group (28.0 [26.0, 30.0]) ( P=0.006). VMMD patients exhibited significant impairments in specific cognitive domains, including visuospatial/executive function, delayed recall, and orientation ( P<0.05). Patients with VM, MD, and VMMD showed higher rates of anxiety, depression, and somatization symptoms compared to the control group ( P<0.05), with the VMMD group experiencing the most severe emotional distress. Multiple linear regression analysis identified education level and vestibular disease type as key factors affecting cognitive function, with a university-level education predicting higher MoCA scores ( P<0.001), while VMMD was associated with cognitive decline ( P<0.01). Conclusions:Patients with VM and MD, particularly those with comorbid VMMD, exhibit significant emotional distress. Cognitive impairments are present in VM and VMMD patients, affecting different cognitive domains. These factors should be comprehensively considered in clinical assessments to develop more effective treatment strategies.

Metabolic-associated fatty liver disease (MAFLD) and osteoporosis (OP) are two very common metabolic diseases. A growing body of experimental evidence supports a pathophysiological link between MAFLD and OP. MAFLD is often associated with the development of OP. Rutaecarpine (RUT) is one of the main active components of Chinese medicine Euodiae Fructus. Our previous studies have demonstrated that RUT has lipid-lowering, anti-inflammatory and anti-atherosclerotic effects, and can improve the OP of rats. However, whether RUT can improve both fatty liver and OP symptoms of MAFLD mice at the same time remains to be investigated. In this study, we used C57BL/6 mice fed a high-fat diet (HFD) for 4 months to construct a MAFLD model, and gave the mice a low dose (5 mg·kg^-1) and a high dose (15 mg·kg^-1) of RUT by gavage for 4 weeks. The effects of RUT on liver steatosis and bone metabolism were then evaluated at the end of the experiment [this experiment was approved by the Experimental Animal Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (approval number: IMB-20190124D₃03)]. The results showed that RUT treatment significantly reduced hepatic steatosis and lipid accumulation, and significantly reduced bone loss and promoted bone formation. In summary, this study shows that RUT has an effect of improving fatty liver and OP in MAFLD mice.

BACKGROUND: Lung cancer is currently the most prevalent malignancy and the leading cause of cancer deaths worldwide. Although the early stage non-small cell lung cancer (NSCLC) presents a relatively good prognosis, a considerable number of lung cancer cases are still detected and diagnosed at locally advanced or late stages. Surgical treatment combined with perioperative multimodality treatment is the mainstay of treatment for locally advanced NSCLC and has been shown to improve patient survival. Following the standard methods of neoadjuvant therapy, perioperative management, postoperative adjuvant therapy, and other therapeutic strategies are important for improving patients' prognosis and quality of life. However, controversies remain over the perioperative management of NSCLC and presently consensus and standardized guidelines are lacking for addressing critical clinical issues in multimodality treatment. METHODS: The working group consisted of 125 multidisciplinary experts from thoracic surgery, medical oncology, radiotherapy, epidemiology, and psychology. This guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The clinical questions were collected and selected based on preliminary open-ended questionnaires and subsequent discussions during the Guideline Working Group meetings. PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) were searched for available evidence. The GRADE system was used to evaluate the quality of evidence and grade the strengths of recommendations. Finally, the recommendations were developed through a structured consensus-building process. RESULTS: The Guideline Development Group initially collected a total of 62 important clinical questions. After a series of consensus-building conferences, 24 clinical questions were identified and corresponding recommendations were ultimately developed, focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assement, and follow-up protocols for NSCLC. CONCLUSIONS This guideline puts forward reasonable recommendations focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assessment, and follow-up protocol of NSCLC. It standardizes perioperative multimodality treatment and provides guidance for clinical practice among thoracic surgeons, medical oncologists, and radiotherapists, aiming to reduce postoperative recurrence, improve patient survival, accelerate recovery, and minimize postoperative complications such as atelectasis.

The renin-angiotensin-aldosterone system (RAAS) is crucial for regulating blood pressure and maintaining fluid balance, while clock genes are essential for sustaining biological rhythms and regulating metabolism. There exists a complex interplay between RAAS and clock genes that may significantly contribute to the development of various cardiovascular and metabolic diseases. Although current literature has identified correlations between these two systems, the specific mechanisms of their interaction remain unclear. Moreover, the interaction patterns under different physiological and pathological conditions need further investigation. This review summarizes the synergistic roles of the RAAS and clock genes in cardiovascular diseases, explores their molecular mechanisms and pathophysiological connections, discusses the application of chronotherapy, and highlights potential future research directions, aiming to provide novel insights for the prevention and treatment of related diseases.

Drug administration via hollow microneedles (HMN) have the advantages of painlessness, avoidance of first-pass effect, capability of sustained infusion, and no need for professional personnel operation. In addition, HMN can also be applied in the fields of body fluid extraction and biosensors, showing broad application prospects. However, traditional manufacturing technologies cannot meet the demand for low-cost mass production of HMN, limiting its widespread application. This paper reviews the main manufacturing technologies used for HMN in recent years, which include photolithography and etching, laser etching, sputtering and electroplating, micro-molding, three-dimensional (3D) printing and drawing lithography. It further analyzes the characteristics and limitations of existing manufacturing technologies and points out that the combination of various manufacturing technologies can improve production efficiency to a certain extent. In addition, this paper looks forward to the future trends of HMN manufacturing technology and proposes possible directions for its development. In conclusion, it is expected that this review can provide new ideas and references for follow-up research.
