Autoimmune liver diseases （AILD） are a group of chronic liver diseases caused by abnormal activation of the immune system， mainly including autoimmune hepatitis， primary biliary cholangitis， primary sclerosing cholangitis， IgG4-related sclerosing cholangitis， and overlap syndrome. Clinical studies have shown that patients with AILD are often comorbid with thyroid diseases， especially autoimmune thyroid diseases （AITD）， such as Graves’ disease and Hashimoto’s thyroiditis. This article systematically reviews the epidemiological association， potential shared pathogenesis， and overlapping features between AILD and thyroid diseases. A deeper understanding of the immunological links between AILD and AITD may provide a theoretical basis for precision medicine and future research.

ObjectiveTo understand the epidemiological distribution and gene evolutionary variation of influenza A (H3N2) viruses in Fengxian District, Shanghai, in the surveillance year of 2023, and to provide a reference basis for influenza prevention and control. MethodsThe prevalence of influenza virus in Fengxian District in the 2023 influenza surveillance year (April 2023‒March 2024) was analyzed. The hemagglutinin (HA) gene, neuraminidase (NA) gene, and amino acid sequences of 75 strains of H3N2 influenza viruses were compared with the vaccine reference strain for similarity matching and phylogenetic evolutionary analysis, in addition to an analysis of gene characterization and variation. ResultsIn Fengxian District, there was a mixed epidemic of H3N2 and H1N1 in the spring of 2023, with H3N2 being the predominant subtype in the second half of the year, and Victoria B becoming the predominant subtype in the spring of 2024. A total of 75 influenza strains of H3N2 with HA and NA genes were distributed in the 3C.2a1b.2a.2a.2a.3a.1 and B.4 branches, with overall similarity to the reference strain of the 2024 vaccine higher than that of the reference strain of the 2022 and 2023 vaccine. Compared with the 2023 vaccine reference strain, three antigenic sites and one receptor binding site were changed in HA, with three glycosylation sites reduced and two glycosylation sites added; where as in NA seven antigenic sites and the 222nd resistance site changed with two glycosylation sites reduced. ConclusionThe risk of antigenic variation and drug resistance of H3N2 in this region is high, and it is necessary to strengthen the publicity and education on the 2024 influenza vaccine and long-term monitoring of influenza virus prevalence and variation levels.

ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）/cAMP-response element binding protein （CREB） signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet， intraperitoneal injection of isoproterenol （ISO）， and chronic unpredictable mild stress （CUMS）. A total of 108 SD male rats were randomly divided into normal group， model group， high （23.4 g·kg^-1）， medium （11.7 g·kg^-1）， and low （5.85 g·kg^-1） dose groups of modified Chaihu Shugansan， CaMKⅡ inhibitor （KN93） group， and KN93 + high， medium， and low dose groups of modified Chaihu Shugansan， with 12 rats in each group. From the first day of modeling to the end of modeling， drugs were administered once a day. In the seventh and eighth weeks， the KN93 group and the KN93 + high， medium， and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week， behavioral tests including sucrose preference， open field， and elevated plus maze were conducted. Electrocardiogram （ECG） lead Ⅱ changes were observed in each group of rats， and hematoxylin-eosin （HE） staining was performed to observe changes in heart tissue. Serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， low-density lipoprotein （LDL）， and lactate dehydrogenase （LDH） were measured by using an enzyme-labeled instrument. Creatine kinase （CK） and creatine kinase-MB （CK-MB） were detected by ultraviolet spectrophotometry， while serum monocyte chemoattractant protein-1 （MCP-1） was measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue， and Western blot was performed to assess protein expression of CaMKⅡ， phosphorylated （p）-CaMKⅡ， CREB， and p-CREB. ResultsCompared to the normal group， the model group showed significant reductions in sucrose preference rate， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）. The ECG showed ST-segment elevation， and HE staining showed serious degeneration of myocardial fibers， disordered arrangement， and infiltration of a large number of inflammatory cells. In addition， serum TC and LDL levels increased （P<0.01）， and HDL level decreased （P<0.01）. CK， CK-MB， LDH， and MCP-1 levels significantly increased （P<0.05， P<0.01）. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue （P<0.05， P<0.01）， but those increased in the heart tissue （P<0.01）. Compared to the model group， the high， medium， and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）， as well as decreased serum CK， CK-MB， LDH， and MCP-1 levels （P<0.05， P<0.01）. KN93 also reduced ST-segment elevation， alleviated the degeneration degree of myocardial fibrosis， and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced （P<0.05， P<0.01）. The KN93 + high， medium， and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression， possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway， with the high-dose modified Chaihu Shugansan showing the best effects.

Objective To understand the challenges faced by elderly patients with multiple chronic conditions in community settings during the process of disease management,and to provide a basis for developing intervention strategies for managing comorbidities in the elderly.Methods A phenomenological research approach was adopted,using purposive sampling.From July to October 2024,16 elderly patients with multiple chronic conditions from 5 community service centers in Shenzhen were selected as study participants.Semi-structured in-depth interviews were conducted,and the interview data were analyzed using Colaizzi's seven-step method.Results Totally 4 themes and 8 sub-themes were extracted,including the disorder of multi-source health information structure and environment(insufficient systematic integration of health guidance,uneven quality of knowledge under multiple information channels),the exhaustion of self-management efficacy among chronic disease patients(the coexistence of multiple diseases aggravates the burden of physical and mental symptoms;negative emotions weaken the efficacy of active management),the absence of an integrated management mechanism for multiple diseases(repeated medical visits lead to poor treatment experience;multiple medications pose potential health risks),and the lack of in-depth and dynamic social support practices(formal operation of community support systems,family support facing the dilemma of filial piety and control).Conclusion Elderly patients with multiple chronic conditions in community settings face numerous challenges in disease management.Current chronic disease management in China primarily focuses on single diseases.It is recommended that healthcare professionals shift their perspective,improve the identification,assessment,nursing,and treatment of comorbidities in the elderly,and provide integrated chronic disease management approaches.This would enable a"one-stop"solution to the management challenges of multimorbidity in elderly patients,thereby enhancing their quality of life.

Objective:To investigate the prevalence of and risk factors associated with Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) and high-risk human papillomavirus (HPV) coinfections among patients with newly diagnosed syphilis at a hospital in Nanjing. Methods:A cross-sectional study was conducted on patients with newly diagnosed syphilis at the STD Clinic, Hospital of Dermatology, Chinese Academy of Medical Sciences in Nanjing, China from May 2023 to April 2024. Urethral, cervical or rectal swabs were collected according to the gender and types of sexual behavior of the patients. Screening tests for CT, NG and HPV infections were then performed by nucleic acid amplification testing. High-risk HPV testing was performed only in female patients. Univariate analysis was carried out to investigate risk factors associated with CT infection. The chi-square test, chi-square test with continuity correction, or Fisher's exact test was chosen based on the sample size and expected values.Results:A total of 111 newly diagnosed syphilis patients with test specimens were collected, including 71 males (64%) and 40 females (36%), and their ages ranged from 16 to 87 years; there were 82 patients with early syphilis and 29 with late latent syphilis; the number of sexual partners in the past 3 months ranged from 0 to 3. Among the 60 male patients with early syphilis, 1 (1.7%) was co-infected with NG, and 12 (20%) with CT; among the 16 men who have sex with men, 7 (43.8%) were co-infected with CT, while 5 (11.4%) of the 44 heterosexual patients were co-infected with CT, showing a significant difference in CT infection rates between the two groups ( χ2 = 5.80, P = 0.016). Among the 22 female patients with early syphilis, 1 (4.5%) was co-infected with NG, and 8 (36.4%) with CT; among the 12 female patients aged < 25 years, 8 (66.7%) were infected with CT, while none of the 7 patients aged 25-44 years or the 3 patients aged ≥ 45 years were infected with CT, showing a significant difference in CT infection rates among the 3 age groups ( P = 0.005) ; among the 16 female patients with 1 sexual partner in the past 3 months, 3 were infected with CT, while 5 were infected with CT in the 6 female patients with 2-3 sexual partners in the past 3 months, with a significant difference in CT infection rates between the two groups ( P = 0.011). Out of the 40 female patients with syphilis, 16 (40%) were co-infected with high-risk HPV; the HPV infection rates did not differ among different age groups (age groups of < 25 years, 25-44 years, ≥ 45 years: 8/14, 2/9, 6/17, respectively; P = 0.265) . Conclusion:The CT infection rate was relatively high in patients with newly diagnosed early syphilis, and a relatively high infection rate of high-risk HPV was observed in female patients with syphilis aged < 25 years.

Objective:To evaluate the safety and efficacy of secondary transport on extracorporeal membrane oxygenation (ECMO) for critically ill children.Methods:This was a retrospective cohort study. Data from 222 pediatric patients who underwent ECMO transport from May 2019 to May 2024 at 5 ECMO centers and Chinese Database of Pediatric Extracorporeal Life Support Organization were collected. The cases were divided into primary and secondary transport groups by nature of transport. The clinical data, including demographics, ECMO indications, transport distance, pre-transport lab results, prognosis and complications were analyzed. Two independent samples t-test, Wilcoxon test, and χ2 test or Fisher′s exact probability method were used to compare the differences between 2 groups and evaluate the safety and efficacy of secondary transport. Results:Among the 222 children transported with ECMO, there were 135 males and 87 females, with an age of 3.0 (0.2, 7.0) years. There were 202 cases in the primary transport group and 20 cases in the secondary transport group. All secondary transport patients had failed attempts at weaning ECMO before transfer. The patients in the secondary transport group were older, had higher rates of surgical cannulation, circulatory support, and pre-ECMO lactate levels compared to the primary transport group (7.0 (2.8, 10.0) vs. 3.0 (0.2, 6.0) years old, 55.0% (11/20) vs. 3.6% (7/202), 80.0% (16/20) vs. 41.6% (84/202), (10±4) vs. (7±6) mmol/L, Z=3.41, χ 2=66.31, 10.99, t=2.24, all P<0.05). In the secondary transport group, the vasoactive-inotropic scores of patients on circulatory support and the oxygenation index for patients requiring respiratory support were higher than those in the primary transport group (83±33 vs. 82±68, 51.0±1.8 vs. 37.4±10.2, t=2.36, 2.63, respectively; both P<0.05). There were no statistically significant differences between the 2 groups in sex, transport distance, pre-ECMO creatinine, arterial blood gas BE values, and ECMO duration (all P>0.05). No life-threatening complications occurred during the transport in either group. Two patients in the secondary transport group underwent heart transplantation, and 1 patient underwent radiofrequency ablation. The overall survival rate between the 2 groups showed no statistically significant difference (45.0% (9/20) vs. 55.4% (112/202), χ2=1.15, P>0.05). Conclusions:Secondary ECMO transport for critically ill children don't increase mortality or life-threatening complications during transport. ECMO patients who cannot receive effective treatment locally can benefit from secondary transport to an advanced ECMO center provides further treatment opportunities.

Objective:To analyze the relationship between the growth and development of pump twin and the changes of blood flow parameters and the natural pregnancy outcome of pump twin after pontaneous cessation of blood flow in the umbilical artery of the acardiac twin with reverse arterial perfusion sequence（TRAPs）detected by prenatal ultrasound.Methods:From January 2001 to August 2023，a total of 23 cases of TRAPs diagnosed in Hubei Maternal and Child Health Hospital were retrospectively collected and detected by ultrasound follow-up. According to the pregnancy outcome of the pump twin，23 patients were divided into the poor pregnancy outcome group（6 cases）and the good pregnancy outcome group（17 cases）. The changes of ultrasound growth indexes and blood flow parameters of the pump twin and acardia twin were compared between the two groups. The hemodynamic parameters with statistically significant differences between the two groups were selected，and the diagnostic efficacy for TRAPs pregnancy outcomes was analyzed using ROC analysis.Results:There were no statistically significant differences in the structural development of acardiac fetus between the two groups，including skin edema，hemicardia，skull structure，trunk structure，upper and lower limbs，cardiothoracic ratio，amniotic fluid，sex and amniotic nature of twins（all P > 0.05）. The lower limbs of acardia twin was significantly higher in the poor pregnancy outcome group（6/6）than in the good pregnancy outcome group（7/17），and the difference was statistically significant（ P < 0.05）. The relevant parameters of ultrasound blood flow were shown in both groups，there were no significant differences in middle cerebral artery pulsation index（PI）and umbilical artery PI between the two groups before natural occlusion of fetal blood flow with TRAPs（all P > 0.05）. In the good pregnancy outcome group，the ratio of umbilical cord diameter between pump twin and acardia twin was higher than that in the poor pregnancy outcome group，the difference was statistically significant（ P < 0.05）. The scatter plot of the ratio of umbilical diameter between the two groups was drawn，and the cut-off value was 2.125 through ROC curve analysis，the area under the curve（AUC）was 0.961，the sensitivity was 94.10%，the specificity was 100%，and the Yoden index was 0.94. Conclusions:The ratio of umbilical cord diameter between pump twin and acardia twin in TRAPs is significant for predicting the pregnancy outcome of pump twin.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Objective To observe the effects of four different modeling method on the hypothalamus-pituitary-adrenal(HPA)axis,blood rheology,platelet aggregation rate,and myocardial ischemia in rats,and to provide new ideas for the establishment of a rat model of"double heart"disease in line with clinical diagnosis and treatment characteristics.Methods Sixty-nine male Sprague-Dawley rats were divided randomly into a Control group(unstimulated),chronic unpredictable mild stimulation(CUMS)group,isoproterenol(ISO)group(intraperitoneal injection of ISO),high-fat diet(HFD)group(fed high-fat chow),and composite model(CUMS+ISO+HFD)group(n=12 rats in the Control and HFD groups;n=15 rats in the other three groups,respectively).Modeling procedures were carried out for a total of 8 weeks,with ISO injection started from week 6 of the experiment for a total of 3 weeks.At the end of modeling,rats in each group were subjected to absent-field and sugar-water preference behavioral tests.Electrocardiography(ECG)was performed to observe changes in ECG lead Ⅱ in each group.Serum levels of adrenocorticotropic hormone(ACTH),cortisol(Cor),corticosterone(CORT),endothelin-1(ET-1),and soluble intercellular adhesion molecule-1(sICAM-1)were detected by enzyme-linked immunosorbent assay.Myocardial histopathological changes were detected by hematoxylin/eosin(HE)staining.Serum total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C)were measured using an enzyme labeling instrument.Whole-blood high-cut viscosity(200 V/S),whole-blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen were assessed using an automatic blood rheology analyzer.The maximum platelet aggregation rate(MAR)and average platelet aggregation rate(AAR)induced by arachidonic acid and adenosine diphosphate were detected using a whole-blood platelet aggregometer.Results Compared with the Control group,all four model groups had significantly lower absenteeism distance and number of entries into the central region in the absent-field test,and a lower sugar-water preference ratio(P＜0.01).ECG revealed ST-segment elevation in the ISO and CUMS+ISO+HFD groups,tachycardia in the CUMS group,and mild ST-segment elevation in the HFD.Serum ACTH,Cor,CORT,ET-1,and sICAM-1 were all significantly elevated in the four model groups(P＜0.01).HE staining showed that myocardial tissue was severely damaged in rats in the ISO and CUMS+ISO+HFD groups,with pathological changes such as localized fibrosis and inflammatory infiltration of the myocardium,while mild cardiomyocyte disarrangement and fracture was seen in the CUMS and HFD groups.Rats in the HFD group had increased serum TC and LDL(P＜0.01)and decreased HDL contents(P＜0.01).Compared with the Control group,whole-blood high-cut viscosity(200 V/S),whole-blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen were all increased in the CUMS,HFD,and CUMS+ISO+HFD groups(P＜0.01,P＜0.05),while whole blood high-cut viscosity(200 V/S),whole blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen levels were decreased in rats in the ISO group(P＜0.01,P＜0.05).MAR and AAR were significantly higher in rats in the CUMS,HFD,and CUMS+ISO+HFD groups(P＜0.01),while the platelet aggregation rate was decreased in the ISO group compared with the Control group(P＜0.01,P＜0.05).Conclusions These result showed that the rat CUMS+ISO+HFD model better reflected the complexity of clinical double heart disease than the other three models.

Objective: To investigate the efficacy, nursing characteristics, and management of different desensitization strategies before allogeneic hematopoietic stem cell transplantation (allo-HSCT) among patients with high level of human leukocyte antigen (HLA) antibodies. Methods: A retrospective analysis was conducted on 82 patients with high levels of HLA antibodies who underwent allo-HSCT at the First Affiliated Hospital of Soochow University and Suzhou Hopes Hematonosis Hospital between January 2020 to November 2023. Patients were divided into two groups based on the desensitization strategy they received: the anti-CD20 monoclonal antibody combined with therapeutic plasma exchange (TPE) group (n=50) and the anti-CD20 monoclonal antibody combined with Protein A immunoabsorption group (n=32). The differences of efficacy between the desensitization strategies were analyzed. The safety of both desensitization strategies were assessed by close monitoring of adverse events throughout the treatment. The nursing characteristics and interventions specific to these strategies were comprehensively summarized. Results: There were no significant differences in age, gender, and diagnosis between the two groups of patients receiving different desensitization strategies (P>0.05). Following desensitization in the immunoadsorption group, the mean fluorescence intensity (MFI) levels of anti-HLA Class I antibody decreased significantly compared to initial screening (P=0.048), while the decrease in MFI values of anti-HLA Class II antibody was not statistically significant (P=0.173). In the TPE group, the MFI levels for both anti-HLA Class I and II antibodies after desensitization decreased significantly compared to initial screening (P=0.025 and 0.028, respectively). Monitoring of adverse events during desensitization treatment, found that patients in the immunoadsorption group experienced mild decreases in blood pressure during the process, with two patients developing severe hypotension. No allergic reactions occurred, and no damage of liver or kidney function was observed after the immunoadsorption. In the immunoadsorption group, a total of 19 patients underwent sera immunoglobulin assays before and after immunoadsorption. Compared to the initial screening, the immunoglobulin G (IgG) levels significantly decreased after immunoadsorption (P<0.001). In TPE group, 12 patients experienced mild hypotension during the plasma exchange process, but no severe hypotension was observed. One patient developed an allergic reaction. After the TPE treatment, no damage of liver or kidney function was observed, nor any decrease of IgG levels. In terms of safety of intravenous access, neither group experienced severe complications such as catheter-related bloodstream infections or deep vein thrombosis. In the TPE group, catheter occlusion occurred during the process of plasma exchange in 2 patients, while no such incident was observed in the immunoadsorption group. Patients of both groups exhibited anxiety and depression before treatment. After psychological care, the scores for anxiety and depression significantly decreased (P<0.001). Conclusion: Both desensitization strategies significantly decreased the HLA antibodies in highly sensitized patients with high level of HLA antibodies undergoing allo-HSCT. For patients receiving immunoabsorption, nursing care should focus on preventing and managing hypotension and implementing infection-prevention measures due to IgG depletion. In contrast, for those undergoing TPE, vigilant monitoring and prompt management of potential allergic reactions are essential components of nursing practice.
