Objective To analyze the trend of influenza epidemic intensity in Urumqi City, Xinjiang, in early 2023, and to provide a reference basis for influenza surveillance, prevention and control. Methods Based on the daily number of influenza cases in Urumqi from January 1, 2023 to March 26, 2023, a generalized linear model was established to correlate the cumulative number of cases with the number of days of illness, and the corresponding doubling time was calculated. Results A total of 9 243 influenza cases were included in this study, including 7733 confirmed cases and 1510 suspected cases. The peak incidence of influenza occurred in March, and 6039 positive cases were detected, with a positivity rate of 78.09%. The age group of 3-6 years old had the highest proportion of influenza positive cases, accounting for 32.20%. The longest doubling time among confirmed cases was 13.49 (95% CI:11.95-15.47) in stage 2 (January 22 to February 13), and the shortest was in stage 3 (February 14 to March 26), which was 9.41 (95% CI:8.24-10.91). Conclusion The shorter the doubling time, the faster the speed of influenza transmission, and it is necessary to strengthen the prevention and control of influenza in winter and spring.

ObjectiveTo investigate the optimal ratio of goat horn replacing antelope horn in Fufang Lingjiao Jiangya pills and the blood pressure-lowering mechanism of this medicine. MethodsThe blood pressure-lowering efficacy of Fufang Lingjiao Jiangya pills with varying proportions of goat horn replacing antelope horn was evaluated on spontaneous hypertensive rats （SHR）. In this experiment， 50 SHR rats were randomly grouped as follows： model （n=8）， captopril （0.01 g·kg^-1） （n=6）， low-dose blank Fufang Lingjiao Jiangya pills （0.342 g·kg^-1） （n=6）， high-dose blank Fufang Lingjiao Jiangya pills （0.684 g·kg^-1） （n=6）， low-dose antelope horn-containing Fufang Lingjiao Jiangya pills （0.378 g·kg^-1） （n=6）， high-dose antelope horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1） （n=6）， low-dose goat horn-containing Fufang Lingjiao Jiangya pills （0.378 g·kg^-1） （n=6）， and high-dose goat horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1） （n=6）. Additionally， 8 WKY rats were used as the normal group. Drugs were administered by gavage for 4 weeks while an equal volume of distilled water was administered for the normal and model groups. Blood pressure was measured before administration， 3 h post administration， and biweekly thereafter. In the experiment for Fufang Lingjiao Jiangya pills with goat horn replacing antelope horn in different proportions， 48 SHR rats were randomly grouped as follows： model， blank Fufang Lingjiao Jiangya pills （0.684 g·kg^-1）， antelope horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1）， 2× goat horn-containing Fufang Lingjiao Jiangya pills （0.824 g·kg^-1）， 4× goat horn Fufang Lingjiao Jiangya pills （0.969 g·kg^-1）， and 6× goat horn Fufang Lingjiao Jiangya pills （1.112 g·kg^-1）. The normal group included 8 WKY rats， and the normal group and model group received an equal volume of distilled water. The treatment lasted for 2 weeks， and blood pressure was recorded at various time points （pre-administration， 3 h post administration， and on days 4， 7， 10， and 14 of administration）. Serum levels of angiotensin-converting enzyme （ACE）， angiotensin Ⅱ（Ang Ⅱ）， renin， and interleukin-6 （IL-6） were measured by enzyme-linked immunosorbent assay. Histopathological changes in the heart， kidney， and thoracic aorta were observed by hematoxylin-eosin staining. The protein levels of ACE2， angiotensin Ⅱ type 1 receptor （AT1R）， and angiotensinogen （AGT） in the kidney tissue were determined by Western blot， while the expression of nuclear factor （NF）-κB p65 and Toll-like receptor 4 （TLR4） in the thoracic aorta tissue was assessed by immunohistochemistry. ResultsCompared with the model group， all treatment groups showed lowered blood pressure （P<0.05， P<0.01）， and the 6× goat horn-containing Fufang Lingjiao Jiangya pills group showed consistent blood pressure-lowering effect with the antelope horn-containing Fufang Lingjiao Jiangya pills group. Compared with the normal group， the model group showed elevated serum levels of ACE， Ang Ⅱ， renin， and IL-6， while the elevations were declined in the Fufang Lingjiao Jiangya pills groups （P<0.05， P<0.01）. Pathological changes in the heart， kidney， and thoracic aorta were alleviated in all the treatment groups， with the 6× goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups exhibited the best effect. Western blot and immunohistochemistry results showed that all the treatment groups exhibited down-regulated protein levels of AT1R， AGT， NF-κB p65， and TLR4 and up-regulated protein levels of ACE2 （P<0.05， P<0.01） compared with model group， with the 6×goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups showcasing the best effect. ConclusionReplacing antelope horn with 6×goat horn in Fufang Lingjiao Jiangya pills can achieve consistent blood pressure-lowering effect with the original prescription. The prescription may exert the effect by inhibiting the renin-angiotensin-aldosterone system （RAAS） and TLR4/NF-κB signaling pathways.

Objective To investigate the effect of high,middle and low dose dexmedetomidine combined with sufentanil on perioperative analgesia and sleep quality in patients with oral cancer.Methods A total of 158 patients undergoing oral cancer surgery in the hospital from January 2023 to June 2024 were selected and divided into group A[n=53,0.6 μg/(kg h)dexmedetomidine+2 μg/kg sufentanil]and group B[n=53,0.4 μg/(kg h)dexmedetomidine+2 μg/kg sufentanil],Group C[n=52,0.2μg/(kg·h)dexmedetomidine+2 μg/kg sufentanil]by random number table method.Stress response indexes[brain-derived neurotrophic factor(BDNF),cortisol(Cor),interleukin-6(IL-6)],bifrequency index and analgcsia nociccption index(BIS,ANI),pain level,T lym-phocyte subsets CD3+,CD4+,CD8+levels,Richards Campbell Sleep Scale(RCSQ)score and adverse reactions were compared between the two groups.Results Compared with 12 h before surgery,serum levels of BDNF,Cor and IL-6 in 3 groups were decreased 48 h after surgery,group A was lower than group B,group C,group B was lower than group C(P＜0.05).Compared with T0,BIS at T1～T3 were significantly different between the 3 groups(P＜0.05),BIS at T1～T3 were lower than those at T0(P＜0.05),and there was no significant difference in BIS at the same time between the 3 groups(P＞0.05),from T,to T3,ANI was higher than that at T0,and ANI in group A was higher than that in group B and group C(P＜0.05).Compared with the preoperative results,the pain scores of the 3 groups were decreased at 1 h,6 h,24 h and 48 h after operation,and the pain scores of group A were lower than those of group B and C,and the pain scores of group B were lower than those of group C(P＜0.05).After operation,CD3+and CD4+were decreased in all 3 groups,group A was lower than group B and group C,group B was lower than group C(P＜0.05),and CD8+was increased in all 3 groups,group A was higher than group B and group C,group B was higher than group C(P＜0.05).Compared with 1 day before the operation,the sleep quality scores of the three groups on the night after the operation and the second night after the operation were all decreased,group A was lower than group B and group C,and group B was lower than group C(P＜0.05).The incidence of hypotension and sinus bradycardia in group A was higher than that in group B and group C(P＜0.05).There was no significant difference in the incidence of hypotension and sinus bradycardia between group B and group C(P＞0.05).There was no significant difference in the incidence of nausea,vomiting and dizziness among the three groups(P＞0.05).Conclusion The analgesic effect of 0.6 μg/(kg·h)dose dexmedetomidine com-bined with sufentanil can effectively reduce the body's stress response and immune suppression,improve sleep quality,but with a greater incidence of intraoperative hypotension and bradycardia.

Cognitive dysfunction has emerged as a significant health challenge in aging societies, among which Alzheimer's disease(AD)and related dementia have become one of the leading causes of death among the elderly.These diseases are characterized by insidious onset and progressive deterioration, often reaching irreversible advanced stages at initial diagnosis, making early detection and prevention imperative.As the frontline of public health management, communities bear the responsibility for screening and managing major chronic diseases.However, community-based cognitive screening in China still remains in its nascent stages, lacking systematic management and prevention guidelines.This guideline, established under a multidisciplinary collaborative framework and adhering to evidence-based medicine principles, systematically reviews and analyzes the latest clinical evidence worldwide.Utilizing the GRADE(Grading of Recommendations Assessment, Development and Evaluation)system to evaluate evidence quality and following the RIGHT(Reporting Items for Practice Guidelines in Healthcare)statement for standardized guideline development, it ultimately presents 17 recommendations through three rounds of Delphi expert consultations.The core recommendations of this guideline is mainly to use digital cognitive scales to conduct large-scale community cognitive screening for the active individuals aged 60 or above.Stratification and staging should be performed based on screening results, and digital cognitive files with quantified risk factor grading should be established, followed by the formulation of personalized artificial intelligence(AI)prevention and control programs.This guide is the first in China and internationally to propose a quantitative grading system for low, medium, and high-risk factors associated with AD and vascular dementia(VD). It aims to provide standardized principles and practical pathways to advance China's ambitious goals: achieving ≥80% public awareness of dementia prevention knowledge, ≥80% cognitive screening rate among the elderly, ≥80% intervention guidance rate for at-risk populations, and ≥50% medical consultation rate for suspected cognitive impairment cases.

Sjögren's syndrome (SS) is an autoimmune disease characterized primarily by oral and periocular dryness. Astragalus-Salvia (AS) and Ophiopogon-Dendrobium (OD) represent two frequently utilized herb pairs in SS treatment. While the combination of AS-OD herb pairs demonstrates clinical efficacy in alleviating SS symptoms, its underlying mechanism remains unclear. This investigation sought to assess the therapeutic effects and elucidate the potential mechanisms of AS-OD in non-obese diabetic (NOD)/Ltj mice with SS. The study utilized NOD/Ltj mice as SS models, administering AS-OD treatment for 10 weeks at doses of 113.1, 226.2, and 339.3 mg·d^-1·20 g^-1. Results demonstrated that AS-OD improved SS symptoms, evidenced by enhanced salivary flow rate, decreased anti-SSA/Ro and anti-SSB/La antibody levels, increased swimming duration, and reduced lactate (LA) and blood urea nitrogen (BUN) levels in NOD/Ltj mice. AS-OD reduced lymphocyte infiltration, enhanced Aquaporin-5 (AQP5) expression in the submandibular gland, decreased inflammatory cytokine levels in the submandibular gland, and reduced the T helper type 17/regulatory T lymphocyte (Th17/Treg) cell ratio in the spleen. Transcriptomic and proteomic analyses indicated AS-OD's involvement in regulating phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT) and Janus kinase 3/signal transducer and activator of transcription 3 (JAK1/STAT3) pathways, with inhibitory effects validated in both NOD/Ltj mice submandibular gland and A-253 cells. Furthermore, AS-OD enhanced cell viability and reduced A-253 cell apoptosis through the PI3K/AKT pathway. In A-253 cells, AS-OD reduced inflammatory cytokine levels, CXC chemokine ligand 9/10 (CXCL9/10), and T-cell chemotaxis by inhibiting the JAK1/STAT3 pathway. AS-OD mitigates SS by suppressing inflammation and immune responses through the PI3K/AKT and JAK1/STAT3 pathways.

Knee osteoarthritis (KOA) is a common chronic degenerative disease that not only causes pain and reduces the quality of life for patients but also imposes a significant societal burden. Clinical pathways can be developed by referencing recommendations from clinical practice guidelines to localize guidelines within the context of integrated traditional Chinese and western medical systems. However, existing clinical pathways suffer from shortcomings such as deficiencies in integrated traditional Chinese and western medical diagnosis and treatment, inadequate shared decision-making between healthcare providers and patients, and suboptimal visualization of clinical pathways. This study aimed to address and optimize the clinical pathway of KOA by comprehensively organizing and localizing the recommended guidelines. The concept of integrated traditional Chinese and western medicine was reflected through the construction of a path of joint decision-making between doctors and patients, emphasizing the coexistence of diagnosis and screening, the combination of clinical and imaging staging, joint decision-making between doctors and patients, and treatment stages. This pathway emphasizes patient-centered approach, with pain relief and functional rehabilitation running parallel, achieving the implementation of evidence-based concepts in practical medical practice. It provides a concrete basis for joint decision-making between doctors and patients in the integrated treatment of KOA with traditional Chinese and western medicine, which helps to improve diagnosis and treatment efficiency and patient quality of life.

Objective To explore the correlation between cardiac remodeling and the occurrence of contrast-associated acute kidney injury(CA-AKI)assessed by echocardiography.Methods A retrospective analysis was conducted on the clinical data of 100 patients with coronary artery disease(CAD)who underwent coronary angiography(CAG)and percutaneous coronary intervention(PCI)from March 2021 to March 2024.The patients were divided into CA-AKI group and non-CA-AKI group according to whether CA-AKI occurred.Baseline data and echocardiographic parameters,inclu-ding left ventricular end-diastolic internal diameter index(LVIDDI),left ventricular end-systolic in-ternal diameter index(LVIDSI),and left ventricular mass index(LVMI),were collected and com-pared between the two groups.Logistic regression analysis was used to screen for independent influen-cing factors of CA-AKI occurrence.Results The level of N-terminal pro-B-type natriuretic peptide(NT-proBNP)in the CA-AKI group was higher than that in the non-CA-AKI group,and the difference was statistically significant(P＜0.001).Compared with the non-CA-AKI group,the CA-AKI group had higher levels of C-reactive protein and glycosylated hemoglobin(HbA1c),as well as a higher proportion of patients with diabetes and anemia,and the differences were statistically significant(P＜0.05).Echocardiographic data showed that LVMI,LVIDDI,and LVIDSI in the CA-AKI group were all higher than those in the non-CA-AKI group,and the differences were statistically sig-nificant(t=2.057,3.429,2.975;P＜0.05).The left ventricular ejection fraction(LVEF)level in the CA-AKI group was lower than that in the non-CA-AKI group,and the difference was statisti-cally significant(t=3.005,P=0.003).Univariate Logistic regression analysis showed that diabe-tes,anemia,inflammation,NT-proBNP,HbA1c,LVMI,LVIDDI,LVIDSI,LVEF,ventricular hy-pertrophy,and ventricular dilation were significantly associated with the occurrence of CA-AKI(P＜0.05).Multivariate Logistic regression analysis results showed that LVMI(OR=3.81;95％CI,1.04 to 8.50;P=0.045),LVIDDI(OR=4.21;95％CI,2.02 to 6.08;P＜0.001),LVIDSI(OR=1.61;95％CI,1.27 to 2.03;P=0.024),ventricular hypertrophy(OR=3.42;95％CI,1.83 to 4.44;P=0.001),and ventricular dilation(OR=2.93;95％CI,1.43 to 3.74;P=0.033)were independent influencing factors for the occurrence of CA-AKI.Conclusion Cardiac remodeling is significantly correlated with the risk of CA-AKI in CAD patients.Clinicians should take protective measures timely for patients with abnormal cardiac structure to prevent the occurrence of CA-AKI.

AIM:To identify transcriptional differences between the ocular surface ectoderm(OSE)and surface ectoderm(SE)using RNA-seq, and elucidate the OSE transcriptome landscape and the regulatory networks involved in its development.METHODS:OSE and SE cells were differentiated from human embryonic stem(hES)cells. Differentially expressed genes(DEGs)between OSE and SE were analyzed using RNA-seq. Based on the DEGs, we performed gene ontology(GO)analysis, Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis, and protein-protein interaction(PPI)network analysis. Transcription factors(TFs)and hub genes were screened. Subsequently, TF-gene and TF-miRNA regulatory networks were constructed using the NetworkAnalyst platform.RESULTS:A total of 4 182 DEGs were detected between OSE and SE cells, with 2 771 up-regulated and 1 411 down-regulated genes in OSE cells. GO-BP analysis revealed that up-regulated genes in OSE were enriched in the regulation of ion transmembrane transport, axon development, and modulation of chemical synaptic transmission. Down-regulated genes were primarily involved in nuclear division, chromosome segregation, and regulation of cell cycle phase transition. KEGG analysis indicated that up-regulated genes in OSE cells were enriched in signaling pathways such as cocaine addiction, axon guidance, and amphetamine addiction, while down-regulated genes were enriched in proteoglycans in cancer, ECM-receptor interaction, protein digestion and absorption, and cytokine-cytokine receptor interaction. Additionally, compared with SE, 204 TFs(including FOS, EGR1, POU5F1, SOX2, and PAX6)were up-regulated, and 80 TFs(including HAND2, HOXB6, HOXB5, HOXA5, and HOXB8)were down-regulated in OSE cells. Furthermore, we identified 6 up-regulated and 9 down-regulated hub genes in OSE cells, and constructed TF-gene and TF-miRNA regulatory networks based on these hub genes.CONCLUSIONS:The transcriptome characteristics of OSE and SE cells were elucidated through RNA-seq analysis. These findings may provide a novel insight for studies on the development and in vitro directed induction of OSE and corneal epithelial cells.
