This article aims to improve the understanding of Lance-Adams syndrome （LAS） in clinical practice. By analyzing the clinical data of a patient diagnosed with LAS in 2021 and conducting a literature review， this article elaborates on the clinical symptoms， pathogenesis， diagnostic methods， and treatment regimens of LAS. LAS is a rare central nervous system disorder characterized by action myoclonus after cerebral hypoxia. The etiology of LAS is mainly associated with cerebral hypoxia， and cardiopulmonary resuscitation and asphyxia are the most common predisposing factors for LAS. Characteristic manifestations on electroencephalography have an important value in diagnosis. Clinicians should enhance their ability to identify LAS through typical clinical symptoms and electroencephalography in the early stage. This article also points out that there are still many challenges in the treatment of LAS， which requires further research and exploration. This article has an important reference value in improving the understanding， diagnosis， and treatment of LAS.

Objective To develop and verify a specific serum bactericidal assay(SBA) in vitro for dysentery serum antibody,in order to evaluate the immune efficacy of dysentery bivalent conjugate vaccine.Methods A standardized SBA was developed by identification of strains, preparation of working bacteria stocks, determination of the percentage recovery rates of working bacteria stocks and complement screening according to the reference method published by WHO reference laboratory in US University of Alabama at Birmingham(UAB), and verified for the specificity, linearity, precision as well as robustness. The titers of 20 pairs of serum samples were determined using the developed SBA method.Results The strains were confirmed to be Shigella flexneri 2a(S.flexneri 2a) and Shigella sonnei(S.sonnei), and their working bacteria stocks were constructed respectively. The percentage recovery rates of working bacteria stocks of the two types were 92% and 94% after cryopreservation for more than 2 h, and 91% and 96% after cryopreservation for 6 months, respectively. The both working dilutions were determined to be 20 000, and the numbers of surviving bacteria were 115 and 109 CFU/spot respectively at this working dilution. Two batches(07634EL and 011834EL) of complements could be used as working complements. The CV of reproducibility of the method was less than 30%, and the inter-assay CV was less than 50%, indicating that the reproducibility and intermediate precision of the method were good. The bactericidal titers of the two serotypes were completely inhibited when the concentrations of homologous dysentery polysaccharide were 50 and 40 μg/mL, respectively, while the inhibition was still lower than 20% even when the concentration of heterologous dysentery polysaccharide increased to 200 μg/mL, which indicated that the method had a good specificity. The logarithmic value of bactericidal titer and the logarithmic value of initial dilution multiple of both two serotypes were significantly negatively correlated, with R~2 of 0.997 4 and 0.996 2, respectively.The antibacterial titers of S.flexneri 2a and S.sonnei antibodies increased significantly compared with those before immunization.Conclusion A standardized SBA in vitro for dysentery specific antibody was successfully developed, which can be used to assess the immune efficacy of dysentery bivalent vaccine.

Objective To explore the regulatory role of Abelson interactor 2(ABI2)in progression and prognosis of gastric cancer.Methods TIMER2.0,GEPIA,Kaplan-Meier Plotter and DAVID databases were used to analyze ABI2 expression in pan-cancer and its association with the prognosis of gastric cancer.Gastric cancer and adjacent tissues from 120 patients undergoing radical gastrectomy in our hospital between January,2016 and October,2018 were examined for ABI2 expression and its correlation with disease progression and prognosis.MGC-803 cell models of ABI2 knockdown and overexpression were established for observing the changes in cell proliferation,migration,and invasion,and the impact of ABI2 expression modulation on xenograft growth was evaluated in nude mice.Results Database analysis and examination of the clinical samples showed that ABI2 was highly expressed in gastric cancer tissues.Survival analysis suggested that gastric cancer patients with a high expression of ABI2 had a reduced postoperative 5-year survival rate(P<0.0001),and further Cox univariate and multivariate survival analyses indicated that a high ABI2 expression was an independent risk factor affecting the patients survival outcomes(P=0.022,HR=1.887,95%CI:1.096-3.249).Enrichment analysis suggested the involvement of ABI2 in Wnt signaling.In MGC-803 cells,ABI2 overexpression promoted cell proliferation and xenograft growth in nude mice,increased the expressions of vimentin and N-cadherin,and lowered E-cadherin expression,while ABI2 knockdown produced the opposite effects.Mechanistic analysis revealed that ABI2 overexpression promoted the expressions of Wnt2 and β-catenin in both MGC-803 cells and the xenografts,and their expressions were significantly lowered by ABI2 knockdown.Conclusion ABI2 is highly expressed in gastric cancer,which affects long-term prognosis of the patients,possible due to its regulatory effect on Wnt signaling to promote proliferation,migration and invasion of gastric cancer cells.

Objective To analyze of the therapeutic effect of Weifuchun capsules combined with quadruple therapy on elderly patients with chronic atrophic gastritis(CAG)infected with Helicobacter pylori(Hp).Methods Elderly Hp-infected CAG patients admitted to Affiliated Hospital of Shaoxing University from April 2019 to April 2023 were divided into a control group(treated with classic quadruple therapy)and an experimental group(treated with Weifuchun capsules combined with classic quadruple therapy)according to different regimens.The clinical treatment effects of two groups of patients were compared,the clinical symptom scores,changes in serum gastrointestinal hormones,inflammatory factors levels before and after treatment,and the adverse reactions and Hp recurrence were compared.Results A totol of 300 patients were included in the study,with 150 cases in each group.After treatment,the clinical symptom score,pepsinogen(PG)Ⅱ,high-sensitivity C-reactive protein(hs-CRP),serum tumor necrosis factor-α(TNF-α),interleukin(IL)-6,and IL-8 levels in the experimental group were lower than those in the control group(P＜0.05),and the levels of PG Ⅰ,gastrin-17(GAS-17)in the serum,and total effective rate were higher than those in the control group(P＜0.05).The difference in the incidence of adverse reactions between the two groups was not statistically significant(P＞0.05),and no Hp recurrence was seen in either group.Conclusion The combination of Weifuchun capsules and classic quadruple therapy has shown good efficacy in treating elderly Hp-infected CAG patients,which can effectively improve the clinical symptoms,regulate gastrointestinal hormone secretion,and has good safety.

Objective:To explore the expression level and clinical significance of serum Hsa_circ_0089761 in patients with cervical cancer.Methods:A total of 107 cervical cancer patients, 80 cervical intraepithelial neoplasia (CIN) patients, and 60 normal control group were selected and analyzed from January 2021 to March 2023 at the Ninth Affiliated People's Hospital of Shanghai Jiao Tong University School of Medicine. We compared the levels of serum Hsa_circ_0089761, squamous cell carcinoma antigen (SCCA), and carcinoembryonic antigen (CEA) among different groups, and analyzed the relationship between the expression level of serum Hsa_circ_0089761 and the clinical and pathological characteristics of cervical cancer. The receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic value of serum Hsa_circ_0089761, SCCA, and CEA levels for cervical cancer. Pearson correlation analysis was used to evaluate the correlation between serum Hsa_circ_0089761 expression levels and SCCA and CEA in cervical cancer patients.Results:The expression levels of serum Hsa_circ_0089761[(2.96±0.95) vs (1.83±0.74), (0.92±0.41)], SCCA[(9.63±1.84)ng/ml vs (2.28±0.65)ng/ml, (1.30±0.27)ng/ml], and CEA[(6.47±2.20)ng/ml vs (1.61±0.57)ng/ml, (1.15±0.12)ng/ml] in the cervical cancer group were significantly higher than those in the CIN group and the control group (all P<0.001), and the serum Hsa_circ_0089761 expression levels in the CIN group were significantly higher than those in the control group ( P<0.001). Cervical cancer patients in stages Ⅲ-Ⅳ, with low differentiation, lymph node metastasis, infiltration depth ≥1/2 of the muscle layer, positive SCCA, and positive CEA had significantly higher levels of serum Hsa_circ_0089761 expression (all P<0.05). The ROC curve analysis showed that the specificity of diagnosing cervical cancer was highest (85.00%) for Hsa_circ_0089761 ≥2.25, and the area under the ROC curve (AUC) for diagnosing cervical cancer in combination with SCCA was highest (0.932, 95% CI: 0.874-0.993), with the highest accuracy (89.30%). The sensitivity of the combination of Hsa_circ_0089761+ SCCA+ CEA in diagnosing cervical cancer was highest (96.26%). The correlation analysis results showed that the serum Hsa_circ_0089761 expression levels in cervical cancer patients were positively correlated with SCCA ( r=0.775, P<0.001) and CEA ( r=0.613, P<0.001). Conclusions:The expression level of serum Hsa_circ_0089761 in cervical cancer patients is significantly increased, which is related to clinical and pathological characteristics. The combination of Hsa_circ_0089761 and SCCA detection has high value in the diagnosis of cervical cancer.

Age-related hearing loss(ARHL)is a common chronic disease that poses a serious threat to the physical and mental health of the elderly in an aging society.It is a sensorineural hearing loss characterized by the loss of auditory hair cells,stria vascularis lesions,apoptosis of spiral ganglia,and degeneration of the audi-tory central nervous system,reducing the quality of life of the patients.This article reviews the research progress in the relationship of ARHL with Alzheimer's disease,depression,and frailty,as well as the daily intervention in ARHL.This review aims to improve people's awareness and attention to the health hazards of ARHL and to delay the occurrence and development of ARHL by implementing daily intervention measures to form a healthy lifestyle.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.
