ObjectiveTo investigate the effect and mechanism of cordycepin in inhibiting fat infiltration after rotator cuff injuries in rats by regulating the Wnt/β-catenin signaling pathway, providing a theoretical basis for clinical treatment of rotator cuff injuries. MethodsFifty SPF-grade female SD rats were used in this study, with 10 randomly selected as the blank group. A rotator cuff injury repair model was established by supraspinatus tendon and suprascapular nerve compression. The successfully modeled rats were randomized into model and low-dose (20 mg·kg-1), medium-dose (40 mg·kg-1), and high-dose (80 mg·kg-1) cordycepin groups. After 6 weeks of treatment, the gait analysis was performed to assess the limb function in rats. Oil red O staining and Masson staining were employed to observe pathological changes in the muscle tissue. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in the serum. Immunohistochemistry (IHC) was employed to detect the expression of peroxisome proliferator-activated receptor γ (PPARγ) and CCAAT/enhancer-binding protein α (C/EBPα), which are markers of adipogenesis. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of Wnt3a, Wnt10b, and β-catenin. ResultsCompared with the blank group, the model group showed decreases in stride length and paw print area (P<0.01), an increase in ratio of wet muscle mass reduction and a decrease in muscle fiber cross-sectional area (P<0.05), and decreased ratios of fat infiltration area and collagen fiber area (P<0.01). Additionally, the model group showed elevated levels of IL-1β, IL-6, and TNF-α (P<0.05), up-regulated protein levels of PPARγ and C/EBPα (P<0.01), and down-regulated mRNA and protein levels of Wnt3a, Wnt10b, and β-catenin (P<0.05, P<0.01). Compared with the model group, the low-, medium-, and high-dose cordycepin groups showed increases in stride length and paw print area (P<0.01), a decrease in ratio of wet muscle mass reduction and an increase in muscle fiber cross-sectional area (P<0.05), and increases in ratios of fat infiltration area and collagen fiber area (P<0.05, P<0.01). In addition, cordycepin lowered the serum levels of IL-1β, IL-6, and TNF-α (P<0.05, P<0.01), down-regulated the protein levels of PPARγ and C/EBPα (P<0.01), and up-regulated the mRNA and protein levels of Wnt3a, Wnt10b, and β-catenin (P<0.05, P<0.01). ConclusionCordycepin can improve the limb function, alleviate rotator cuff muscle atrophy, fat infiltration, and fibrosis, and inhibit inflammation in rats by regulating the Wnt/β-catenin signaling pathway.

ObjectiveTo observe the effect of Yifei Jianpi prescription on the of signal transducer and activator of transcription protein 1 (STAT1)/interferon regulatory factor 3 (IRF3) signaling pathway in a pneumonia model induced by lipopolysaccharide (LPS) and to explore the mechanism of Yifei Jianpi prescription in improving lung immune and inflammatory responses. MethodsSixty male SPF SD rats were used in this study. Ten rats were randomly assigned to the normal control group, and the remaining 50 were instilled with LPS in the trachea to establish a pneumonia model. After successful modeling, the rats were randomly divided into the model group, dexamethasone group (0.5 mg·kg-1), and Yifei Jianpi prescription high-dose (12 mg·kg-1), medium-dose (6 mg·kg-1), and low-dose (3 mg·kg-1) groups, with 10 rats in each group. Treatment was administered once daily, and the normal control and model groups received the same volume of normal saline. After 14 days, flow cytometry was used to detect the classification of whole blood lymphocytes. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of immunoglobulin G (IgG), immunoglobulin A (IgA), immunoglobulin M (IgM), and the content of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-6 (IL-6), and interleukin-10 (IL-10) in alveolar lavage fluid (BALF). Hematoxylin-eosin (HE) staining was used to observe lung tissue pathology and score the damage. Thymus weight, spleen weight, and wet-to-dry weight ratio (W/D) were recorded. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of STAT1, IRF3, IL-6, and interferon-alpha (IFN-α) in lung tissues, while Western blot was performed to assess the protein expression of STAT1, IRF3, IL-6, and IFN-α. ResultsCompared with the normal control group, the model group showed significantly increased proportion of B lymphocytes in peripheral blood, decreased proportions of NK cells and CD4+/CD8+ (P<0.05, P<0.01), decreased serum levels of IgG and IgA, significantly increased IgM levels (P<0.01), significantly elevated content of TNF-α, IL-6, and IL-8 in BALF, and significantly decreased IL-10 levels (P<0.01). Lung tissue damage was evident, with significant increases in thymus and spleen weights and a higher W/D ratio (P<0.01). The mRNA and protein expression of STAT1, IRF3, IFN-α, and IL-6 in lung tissues was significantly upregulated (P<0.05,P<0.01). Compared with the model group, the Yifei Jianpi prescription groups showed significantly reduced proportions of B lymphocytes in peripheral blood, increased proportions of NK cells and CD4+/CD8+ ratios (P<0.05, P<0.01), significantly increased serum levels of IgG and IgA, significantly decreased IgM levels (P<0.05, P<0.01), significantly reduced levels of TNF-α, IL-6, and IL-8 in BALF, and significantly increased IL-10 levels (P<0.01). Lung tissue damage was alleviated, thymus and spleen weights were significantly reduced, and the W/D ratio was markedly decreased (P<0.01). The mRNA and protein expression of STAT1, IRF3, IFN-α, and IL-6 in lung tissues was significantly downregulated (P<0.05, P<0.01). ConclusionYifei Jianpi prescription can alleviate lung tissue damage and improve immune and inflammatory responses in LPS-induced pneumonia rats. The mechanism may be related to the inhibition of STAT1/IRF3 signaling pathway activation.

ObjectiveTo introduce the three main techniques for tuberculosis screening currently used in China, to systematically evaluate their accuracy in diagnosing latent tuberculosis infection (LTBI), so as to provide scientific basis and recommendations for the formulation of China’s tuberculosis screening strategy. MethodsLiterature on the diagnosis of tuberculosis by tuberculin skin test (TST), interferon-γ release assay (IGRA), and recombinant Mycobacterium tuberculosis fusion protein (EC) skin test from January 1, 2010 to August 22, 2024 was comprehensively retrieved from PubMed, China National Knowledge Infrastructure (CNKI), and Wanfang Database through computerized search. Besides, all the literature was screened in accordance to the inclusion criteria for diagnostic tests, and characteristic information of the literature selected was extracted simultaneously. Meta-analysis was performed using Stata 17.0 software, with a random-effects model used for weighted quantitative synthesis of included literature, calculating pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and their 95% confidence intervals (CI). ResultsA total of 543 relevant articles were retrieved, with 105 ultimately included. Among them, 33 articles reported diagnostic data for TST, with a pooled sensitivity of 0.68 (95%CI: 0.62‒0.73), specificity of 0.67 (95%CI: 0.60‒0.73), positive likelihood ratio of 2.0 (95%CI: 1.7‒2.5), and negative likelihood ratio of 0.48 (95%CI: 0.40‒0.58). Ninety-four articles reported the diagnostic value of IGRAs test, with a pooled sensitivity of 0.88 (95%CI: 0.87‒0.89), specificity of 0.82 (95%CI: 0.79‒0.84), positive likelihood ratio of 4.8 (95%CI: 4.2‒5.6), and negative likelihood ratio of 0.15 (95%CI: 0.13‒0.17). Data on EC skin test was limited, but preliminary analysis showed that it had high sensitivity and specificity. ConclusionIGRA has a significant advantage in diagnosing LTBI, and EC skin test also shows good diagnostic performance, although relevant data is limited. TST remains suitable for large-scale screening due to its cost-effectiveness.

To analyze the treatment strategy for a 78-year-old female patient with mismatch repair deficient (dMMR) gastric cancer who achieved long-term survival. After third-line chemotherapy failed, gene testing showed ARID1A p.Gln748fs, c.2733-1G>T variation, with PD-L1 TPS 30%, CPS 60%. The nivolumab was employed, and two weeks later, the best response was partial response (PR). During the fourth-line immunotherapy maintenance treatment, progression of left adrenal metastasis was observed. The expression of human epidermal growth factor receptor-2 (HER-2) was positive, and the antibody drug conjugate disitamab vedotin (RC48) was chosen for treatment. After 10 months of treatment with nivolumab combined with RC48, the best efficacy was assessed as stable disease (SD), with a progression free survival (PFS) of up to 12 months. Radiotherapy was employed, and immunotherapy was maintained, allowing the patient to achieve a PFS of 18 months again. During immunotherapy, a clinical pharmacist developed a personalized pharmaceutical care plan for this patient. At the last follow-up, this patient achieved 78 months of long-term survival.

ObjectiveTo explore the influence of "Internet plus" postpartum health care service on postpartum depression, and to provide an evidence for reducing the incidence of postpartum depression and improving the quality of life for postnatal women. MethodsMothers who gave birth between August 1, 2021 and June 30, 2023 lived in the six streets of Xuhui District were selected as the research subjects. The puerperants were randomly divided into the intervention group and the control group according to the order of enrollment using a numerical numbering system, with 210 cases in each of the intervention group and control group. The intervention group adopted the "Internet plus" postpartum health care services, while the control group adopted the conventional postpartum health care services. The risk factors related to postpartum mental health and the incidence of postpartum depression were compared between the two groups. ResultsThere was no statistically significant difference in the scores of postpartum mental health-related risk factors between the two groups at the first 2 weeks and 1st month after delivery (t=0.736 and t=1.260, P>0.05). However, there was a statistically significant difference in the scores of postpartum mental health-related risk factors at the 3rd months after delivery and 6th months after delivery (t=2.089, P<0.05; t=2.655, P<0.05). There was no statistically significant difference in depression scores at the first 2 weeks after the birth (t=0.560, P>0.05). In the 1st month, the 3rd month and the 6th month after delivery, the intervention group adopted the "Internet plus" postpartum health care service, thus the differences in depression scores were statistically significant (t=2.616, t=2.793 and t=3.107, P<0.05). Conclusion"Internet plus" postpartum health care service is conducive to reducing postpartum depression, promoting maternal mental health, and significantly improving the well-being of postnatal women.

Inflammation is involved in the development of various acute and chronic diseases in the body. Sustained inflammatory responses are key driving factors for diseases such as cancer, neurodegenerative diseases, cardiovascular diseases, metabolic syndrome, inflammatory bowel disease, and arthritis. Therefore, finding anti-inflammatory drugs is crucial for the prevention and treatment of various diseases. In recent years, there has been increasing attention to finding natural drugs with minimal toxic side effects. Lonicerae Japonicae Flos and Lonicerae Flos, as traditional Chinese medicines potent in clearing heat and removing toxins, have strong biological activity and multiple pharmacological effects. They are widely distributed in the plant world and have significant medicinal value. With the continuous advancement of the research on Lonicerae Japonicae Flos and Lonicerae Flos, they have been widely used in the medical field and possess great development potential. Currently, research mainly focuses on the anti-inflammatory mechanisms of Lonicerae Japonicae Flos and Lonicerae Flos, while systematic summaries of their anti-inflammatory active ingredients are rare. Therefore, this paper focuses on the differential analysis of the anti-inflammatory active components of Lonicerae Japonicae Flos and Lonicerae Flos. In addition, it reviewed the possible mechanisms by which extracts and active ingredients of Lonicerae Japonicae Flos and Lonicerae Flos may exert anti-inflammatory effects through various pathways, such as influencing the release of cellular inflammatory factors, regulating inflammatory signaling pathways such as nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), signal transducer and activator of transcription 3 (STAT3), MAPK/extracellular signal-regulated kinase (ERK)/c-Jun N-terminal kinase (JNK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/NF-κB, and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathways, increasing antioxidant stress capacity, enhancing immune defense capabilities, and improving intestinal microbiota, aiming to provide a theoretical basis for the rational clinical application of Lonicerae Japonicae Flos and Lonicerae Flos.

ObjectiveTo investigate the trends and significant determinants of delayed HIV diagnosis (DHD) among newly reported HIV/AIDS cases in Xuhui District, Shanghai between 2018 and 2022. MethodsIn the newly reported HIV/AIDS cases, patients died within one year without accident, HIV/AIDS cases with CD4 cell count <200 cells·μL-1, and AIDS cases with a CD4 cell count between 200 to 499 cells·μL-1 were defined as delayed diagnosis. Univariate and multivariate logistic analysis were employed to explore the influencing factors of DHD. ResultsAmong the 862 newly reported HIV/AIDS cases, The DHD rate was 39.79% without statistically significant difference by year(χ2=4.508, P=0.342). Patients with CD4 cell count <200 cells·μL-1 contributed the largest proportion of DHD. During 2018‒2022, the DHD rate declined among HIV/AIDS patients who were younger than 35 years old or 45‒65 years old, never married, original diagnosis from tertiary specialized hospitals. Patients who were 65 years or older, married or divorced, with heterosexual transmitted HIV/AIDS, and original diagnosis from other types of testing and tertiary metropolitan hospital, had sustainably higher DHD rates. The number of HIV screening and diagnosed from voluntary counseling and testing (VCT) decreased during the COVID-19 epidemic, while the DHD rate increased sharply. Multivariate logistic regression analysis suggested the DHD rates were higher among older age, other types of testing(OR=3.805, 95%CI: 2.260‒6.406)and pre-operative testing(OR=2.411, 95%CI: 1.424‒4.081). Patients who received CD4 test in 15 days had a higher DHD rate compared to the cases received CD4 test exceeding 90 days (OR=0.336, 95%CI: 0.216‒0.522). ConclusionThere is no significant decrease of delayed HIV diagnosis rate in Xuhui District in recent years, and the number of HIV tests has decreased in 2022. Monitoring of newly reported HIV/AIDS should be conducted continuously. Expansion of HIV antibody screening should be conducted in non-infectious departments and inpatient departments in healthcare institutions, particularly metropolitan hospitals. Assistance should be provided to clinicians and elderly patients for improving their ability to recognize and perceive the risk of HIV/AIDS, in order to enhance early diagnosis and subsequent treatment.

ObjectiveTo investigate the high-risk detection rate and aggregation of cardiovascular diseases(CVD) in 8 districts of Shanghai and influencing factors, and to provide scientific references for prevention and control of CVD. MethodsBased on the Cardiovascular Disease Screening and Management Program in Shanghai from 2016 to 2021, 104 685 participants aged 35 to 75 in 8 districts of Shanghai were selected for analysis. χ2 test and multivariate logistic regression were used for statistical analysis of the influencing factors of CVD and aggregation of CVD. ResultsThe proportion of high-risk CVD individuals in the population was 19.17%, including the high-risk individuals with hypertension (8.65%), dyslipidemia (6.33%), CVD history (5.58%), and WHO assessed risk ≥20% types (2.69%), respectively. Old age, overweight and obesity, central obesity, smoking, drinking, farmers, unmarried, and low family income were the risk factors of CVD, while high education level was the protective factor. In the participants, 16 323 people (81.34%) were classified as CVD high-risk groups; The number of aggregation of 1, 2 and ≥3 high risk types of CVD were 16 323(81.34%), 3 236(16.13%), 509(2.54%), respectively. Old age, low education level, low annual family income, farmers, unmarried, smoking, drinking, overweight, obesity and central obesity were associated with the risk of aggregation of high risk types of CVD, and the correlation strength increased with the increase of aggregation types. ConclusionThe prevention and control of CVD in Shanghai should focus on the hypertension, elderly, overweight, obesity, central obesity, smoking, drinking, low educated, low family income, farmers and unmarried people, and targeted intervention measures should be taken to reduce the risk of CVD among residents.
