Objective To understand the antibody levels of diphtheria and tetanus among healthy population in Shanghai Pudong New Area, and to provide a scientific basis for improving the vaccine immunization strategy. Methods Random sampling was used to select healthy people of all ages in 16 communities in Shanghai Pudong New Area from 2018 to 2024, and serum samples were collected and tested for serum anti-diphtheria and tetanus toxin IgG antibodies by enzyme-linked immunosorbent assay (ELISA) method to analyze the antibody positivity rate (≥0.1 IU/ml) and the geometric mean concentration (GMC) of antibodies. Results A total of 3 312 serum samples were included, with a male-to-female ratio of 0.76:1, and 53.77% were local residents. The seropositivity rates and geometric mean concentrations (GMC) of both diphtheria and tetanus antibodies generally declined with increasing age, but exhibited a transient rebound in the 7y-. A total of 1 175 individuals (35.48%) were seropositive for diphtheria, with a GMC of 0.054 IU/mL. For tetanus, 988 individuals (29.83%) were seropositive, with a GMC of 0.033 IU/mL. Significant differences in seropositivity rates (χ2diphtheria=950.005,χ2tetanus=1 324.393) and GMC (Hdiphtheria=1027.160,Htetanus=1 142.007) were observed among different age groups (P<0.001). Significant differences in seropositivity rates (χ2diphtheria=950.005,χ2tetanus=1324.393) and GMC (Hdiphtheria=1027.160,Htetanus=1142.007) were also found across different years (P<0.001). Conclusion The prevalence of diphtheria and tetanus antibodies in the healthy population of Pudong New Area is relatively low, particularly among adults over 20 years of age with inadequate immunization. This underscores the need to reinforce the National Immunization Program (NIP) vaccine specifications for children under 6 years of age and implement an immunization strategy for adolescents or adults against diphtheria and tetanus.

ObjectiveTo explore the establishment of performance assessment indicators for the classification and grading of public health staff in district-level Centers for Disease Control and Prevention (CDCs), and to provide a basis for such evaluations. MethodsThrough literature review and group interviews, performance evaluation indicators were developed based on competency evaluation. Experts were invited to evaluate the weight of performance evaluation indicators for public health staff from different categories, with the average value used to represent the weight of each indicator. ResultsTwenty-nine experts from universities in Shanghai, municipal CDCs, and district CDCs participated, yielding an expert authority coefficient of 0.86. The performance evaluation indicators for department managers were categorized into three levels, with 4 indicators at the primary level, 16 indicators at the secondary level, and 42 indicators at the tertiary level, while those for general staff included 4 primary indicators, 15 secondary indicators, and 36 tertiary indicators. Significant differences were observed in the weight coefficients of the primary indicators (internal operations, professional work, and learning and growth) between department managers and general staff. The top three secondary indicators for department managers were department management, monitoring and prevention, and level of expertise. For mid-level and senior staff, the top three secondary indicators were monitoring and prevention, level of expertise, and research work. The top three secondary indicators for junior staff were monitoring and prevention, professional expertise, and professional attitude. No significant statistical differences were found among tertiary indicators. ConclusionThe developed performance evaluation indicators are reliable. Staff at different levels and classifications should be evaluated using different performance evaluation standards to accurately reflect individual performance and contributions.

Objective:
Neuronal apoptosis is considered to be a critical process in spinal cord injury (SCI). Despite growing evidence of the antiapoptotic, anti-inflammatory, and modulation of ischemic injury tolerance effects of extracellular ubiquitin (eUb), existing studies have paid less attention to the impact of eUb in neurological injury disorders, particularly in SCI. This study aimed to investigate whether eUb can play a protective role in neurons, both in vitro and in vivo, and explores the underlying mechanisms.
Methods:
By utilizing an oxygen glucose deprivation cellular model and a SCI rat model, we firstly investigated the therapeutic effects of eUb on SCI and further explored its effects on neuronal autophagy and mitochondria-dependent apoptosis-related indicators, as well as the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mechanical target of rapamycin (mTOR) signaling pathway.
Results:
In the SCI models both in vivo and in vitro, early intervention with eUb enhanced neuronal autophagy and inhibited mitochondrial apoptotic pathways, significantly mitigating SCI. Further studies had shown that this protective effect of eUb was mediated through its receptor, CXC chemokine receptor type 4 (CXCR4). Additionally, eUb-enhanced autophagy and antiapoptotic effects were possibly associated with inhibiting the PI3K/Akt/mTOR pathway.
Conclusion
In summary, the study demonstrates that early eUb intervention can enhance autophagy and inhibit mitochondrial apoptotic pathways via CXCR4, protecting neurons and promoting SCI repair.

OBJECTIVE To optimize the forming process of Yindan huoxue tongyu granules, and evaluate the quality of the granules. METHODS Taking forming rate, angle of repose, moisture, moisture absorption rate and dissolution rate as indexes, single factor experiment combined with Plackett-Burman design was adopted to screen key process parameters; analytic hierarchy process combined with entropy weight method and Box-Behnken response surface method were used to optimize the molding process of Yindan huoxue tongyu granules, and the forming process was verified. The relative homogeneity index, bulk density, vibration density, Hausner ratio, angle of repose, moisture and hygroscopicity were used as secondary physical indexes to establish the physical fingerprints of 10 batches of Yindan huoxue tongyu granules to evaluate particle quality consistency. RESULTS The optimal molding process of Yindan huoxue tongyu granules was as follows: mannitol as the fixed excipient, the drug-assisted ratio was 1∶1(m/m) and the drying time was 1 h; 90% ethanol was used as wetting agent and the amount of it was 32%, the drying temperature was 70 ℃. The results of validation tests showed that the average comprehensive score was 97.45, which was close to the predicted value of 97.18. The similarities between the physical fingerprints of 10 batches of Yindan huoxue tongyu granules prepared by the optimal molding process and the reference physical fingerprint were all higher than 0.99. CONCLUSIONS The molding process is stable and feasible, and the quality of Yindan huoxue tongyu granules produced is stable and controllable.

The historical development of endogenous wind (内风) is traced with time as the thread, based on the progression of factors such as syndromes, causes of disease, and pathogenesis. It is believed that the concept of wind syndrome originated in The Inner Canon of Yellow Emperor (《黄帝内经》), encompassing both exogenous wind (外风) and endogenous wind syndrome. Over time, exogenous wind syndrome gradually evolved into mild syndromes and severe syndromes, while endogenous wind syndrome emerged from severe syndromes of exogenous wind. Endogenous wind syndrome has both syndrome and pathogenic attributes, and its theoretical system has gradually become more refined. Based on the theories of ancient and modern medical practitioners, and combining the holistic perspectives with Xiang (象) thinking, it is proposed that endogenous wind has both physiological and pathological distinctions. The physiological endogenous wind refers to the liver's moderate dispersing and regulating function, which helps to distribute qi (气), blood, and body fluids, while pathological endogenous wind arises from abnormal liver dispersal. Therefore, in clinical practice, different treatment methods, such as tonifying, unblocking, and warming, can be applied according to the differentiation of deficiency and excess in the pathogenesis.

Objective:
To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes.
Methods:
The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model.
Results:
A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915).
Conclusion
The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

Thyroid diseases are common clinical endocrine disorders, and their pathogenesis is generally considered to be closely related to genetic predisposition factors, immune system disorders, hormone levels, etc. Xiaoyaosan is widely used in the treatment of various thyroid diseases with excellent effects. This study summarized the relevant literature on the treatment of thyroid diseases with modified Xiaoyaosan prescriptions and their active ingredients from aspects such as theoretical analysis, clinical research, and mechanism research. Theoretical analysis revealed that Xiaoyaosan could not only disperse stagnated liver qi but also replenish deficient spleen Qi, which was consistent with the etiology and pathogenesis of thyroid diseases. Clinical studies found that Xiaoyaosan and its modified prescriptions could be widely used in the treatment of multiple thyroid diseases, such as hyperthyroidism, Hashimoto's thyroiditis, and thyroid nodules. Both the use of modified Xiaoyaosan alone and in combination with medications such as methimazole, propylthiouracil, and euthyrox could effectively improve patients' clinical symptoms. In the mechanism research, this study discovered that the whole formula of Xiaoyaosan and its modified prescriptions could inhibit inflammatory reactions, regulate immune balance, and delay liver damage during the treatment of thyroid diseases. The research on Xiaoyaosan for treating thyroid diseases mainly focused on thyroid cancer, autoimmune thyroiditis, hyperthyroidism, and hypothyroidism. The mechanisms of action mainly involved promoting cell apoptosis, inhibiting cell proliferation and migration, arresting the cell cycle, and regulating thyroid hormone levels. In conclusion, this study systematically combs and summarizes the research status of Xiaoyaosan in treating thyroid diseases through literature retrieval, aiming to provide new perspectives and new ideas for the prevention and treatment of thyroid diseases with traditional Chinese medicine.

Objective: To evaluate the efficacy and safety of the single-use hemoperfusion device (UA230) in treating refractory gout (RG) via plasma perfusion. Methods: Thirty-four RG patients aged 18-65 years were recruited and randomly divided into a control group (febuxostat therapy, n=17) and an experimental group (plasma perfusion combined with febuxostat therapy, n=17). Differences in serum uric acid (SUA) levels and urate-lowering rates between the two groups were analyzed using t-tests. Between-group differences in incidence of adverse reactions were analyzed using chi-square tests. Results: At 7 and 14 days post-treatment, SUA levels in the experimental group were significantly lower than those in the control group, with a higher urate-lowering rate (all P<0.05). However, no statistically significant differences in SUA levels or urate-lowering rate were observed at 28 days post-treatment (all P>0.05). The incidence of adverse reactions showed no significant difference between the two groups (χ
=0.15, P>0.05). Conclusion: The single-use hemoperfusion device (UA230), combined with plasma perfusion technology, is a safe and effective treatment for RG. It may serve as a novel therapeutic approach for RG patients in clinical practice.

To explore the inhibitory effect of ginkgolide B (GB) on MH7A human fibroblast-like synoviocytes (FLS) and its potential mechanism. Firstly, 20 μg/L tumor necrosis factor-α (TNF-α) was pretreated with MH7A to establish a cell model of arthritis. After incubation of MH7A cells with various concentrations of GB, CCK-8 assay, Transwell assay, and flow cytometry (FCM) were separately used to detect cell viability, cell invasion, and cell apoptosis rate and cell cycle; Real-time quantitative PCR and Western blot assay were performed to detect the apoptosis- and cycle-related gene transcriptions and protein expressions, respectively. The results showed that compared with the control group, GB dose- and time-dependently suppressed cell viability to a greater extent; GB significantly reduced cell invasive ability and increased cell apoptosis rate and proportion of G0/G1 phase in MH7A cells, along with increased transcription levels of Bcl-2-associated X protein (Bax) and p21 mRNA and decreased transcription levels of Bcl-2, myeloid cell leukemia 1(Mcl-1), protein kinase B (PKB; AKT), IP3K, Cyclin D1 and cyclin-dependent kinase 4 (CDK4) mRNA; GB remarkably increased expression levels of Bax, p21, and cleaved-Caspase 3 protein and decreased expression levels of Bcl-2, Mcl-1, p-AKT, p-PI3K, Cyclin D1, and CDK4 protein, with decreased ratios of p-PI3K/PI3K, p-AKT/AKT, and Bcl-2/Bax. In conclusion, GB blocks the G1-to-S cell cycle transition, suppresses cell viability and cell invasion and induces cell apoptosis of MH7A human RA-FLS via suppressing the PI3K/AKT signaling pathway.
