Objective:
To analyze the epidemiological characteristics and influencing factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhejiang Province from 2019 to 2023, so as to provide the reference for strengthening SFTS prevention and control.
Methods:
Data on laboratory-confirmed SFTS cases in Zhejiang Province from 2019 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data, geographic environment and socioeconomic factors during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts, Geospatial Data Cloud, and Zhejiang Statistical Yearbook, respectively. Descriptive epidemiological methods were used to analyze the epidemiological characteristics of SFTS from 2019 to 2023, and a Bayesian spatio-temporal model was constructed to analyze the influencing factors of SFTS incidence.
Results:
A total of 578 SFTS cases were reported in Zhejiang Province from 2019 to 2023, with an annual average incidence of 0.23/105. The peak period was from May to July, accounting for 52.60%. There were 309 males and 269 females, with a male-to-female ratio of 1.15∶1. The cases were mainly aged 50-<80 years, farmers, and in rural areas, accounting for 82.53%, 77.34%, and 75.43%, respectively. Taizhou City and Shaoxing City reported more SFTS cases, while Shaoxing City and Zhoushan City had higher annual average incidences of SFTS. The Bayesian spatio-temporal interaction model showed good goodness of fit. The results showed that mean temperature (RR=1.626, 95%CI: 1.111-2.378) and mean wind speed (RR=1.814, 95%CI: 1.321-2.492) were positively correlated with SFTS risk, while altitude (RR=0.432, 95%CI: 0.230-0.829) and population density (RR=0.443, 95%CI: 0.207-0.964) were negatively correlated with SFTS risk.
Conclusions
SFTS in Zhejiang Province peaks from May to July. Middle-aged and elderly people and farmers are high-risk populations. Taizhou City, Shaoxing City, and Zhoushan City are high-incidence areas. Mean temperature, mean wind speed, altitude, and population density can all affect the risk of SFTS incidence.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

ObjectiveTo investigate the value of different noninvasive diagnostic models in the diagnosis of esophageal and gastric varices since there is a high risk of esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension, and to provide a basis for the early diagnosis of esophageal and gastric varices. MethodsA total of 108 patients with significant portal hypertension due to compensated hepatitis B cirrhosis who attended Guangdong Provincial Hospital of Traditional Chinese Medicine from November 2017 to November 2023 were enrolled, and according to the presence or absence of esophageal and gastric varices under gastroscopy, they were divided into esophageal and gastric varices group (GOV group) and non-esophageal and gastric varices group (NGOV group). Related data were collected, including age, sex, imaging findings, and laboratory markers. The chi-square test was used for comparison of categorical data between groups; the least significant difference t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of five scoring models, i.e., fibrosis-4 (FIB-4), LOK index, LPRI, aspartate aminotransferase-to-platelet ratio index (APRI), and aspartate aminotransferase/alanine aminotransferase ratio (AAR). The binary logistic regression method was used to establish a combined model, and the area under the ROC curve (AUC) was compared between the combined model and each scoring model used alone. The Delong test was used to compare the AUC value between any two noninvasive diagnostic models. ResultsThere were 55 patients in the GOV group and 53 patients in the NGOV group. Compared with the NGOV group, the GOV group had a significantly higher age (52.64±1.44 years vs 47.96±1.68 years, t=0.453, P<0.05) and significantly lower levels of alanine aminotransferase [42.00 (24.00 — 17.00) U/L vs 82.00 (46.00 — 271.00) U/L, Z=-3.065, P<0.05], aspartate aminotransferase [44.00 (32.00 — 96.00) U/L vs 62.00 (42.50 — 154.50) U/L,Z=-2.351, P<0.05], and platelet count [100.00 (69.00 — 120.00)×109/L vs 119.00 (108.50 — 140.50)×109/L, Z=-3.667, P<0.05]. The ROC curve analysis showed that FIB-4, LOK index, LPRI, and AAR used alone had an accuracy of 0.667, 0.681, 0.730, and 0.639, respectively, in the diagnosis of esophageal and gastric varices (all P<0.05), and the positive diagnostic rates of GOV were 69.97%, 65.28%, 67.33%, and 58.86%, respectively, with no significant differences in AUC values (all P>0.05), while APRI used alone had no diagnostic value (P>0.05). A combined model (LAF) was established based on the binary logistic regression analysis and had an AUC of 0.805 and a positive diagnostic rate of GOV of 75.80%, with a significantly higher AUC than FIB-4, LOK index, LPRI, and AAR used alone (Z=-2.773,-2.479,-2.206, and-2.672, all P<0.05). ConclusionFIB-4, LOK index, LPRI, and AAR have a similar diagnostic value for esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension, and APRI alone has no diagnostic value. The combined model LAF had the best diagnostic efficacy, which provides a certain reference for clinical promotion and application.

Nervous system diseases, also known as neuropathies, encompass a wide range of conditions, primarily including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease, and other neurodegenerative disorders, as well as depression, subarachnoid hemorrhage, cerebral ischemia-reperfusion injury, vascular dementia, and other neurological diseases. These diseases pose serious threats to the health and lives of patients, bringing heavy burdens to society and families. The pathogenesis of nervous system diseases is highly complex, involving mechanisms such as neuroinflammation, oxidative stress, apoptosis, endoplasmic reticulum stress, mitochondrial dysfunction, brain-derived neurotrophic factor deficiency, reduced cholinergic activity, axonal injury, and demyelination. In recent years, the incidence and mortality of nervous system diseases have been rising annually. Currently, western medicine primarily focuses on symptomatic treatment, often accompanied by many adverse reactions, including lethargy, excessive sedation, dizziness, headaches, tachycardia, liver function damage, metabolic disorders, and incomplete recovery after surgery. As a traditional Chinese medicine, Salviae Miltiorrhizae Radix et Rhizoma has effects such as promoting blood circulation, removing blood stasis, cooling the blood, clearing the heart, nourishing the blood, and calming the nerves. It can play a role in the treatment and protection against nervous system diseases through multiple targets, pathways, and mechanisms. Studies have found that the water-soluble phenolic acids and fat-soluble diterpenoid quinones in Salviae Miltiorrhizae Radix et Rhizoma are the main active ingredients for the treatment of nervous system diseases. This paper summarized the effects of the active components and compounds of Salviae Miltiorrhizae Radix et Rhizoma on nervous system diseases over the past ten years, aiming to provide a theoretical basis and research ideas for the development and application of active components and compounds of Salviae Miltiorrhizae Radix et Rhizoma in nervous system diseases.

This article systematically analyzes the historical evolution of the name, origin, quality evaluation, harvesting, processing and other aspects of Picrorhizae Rhizoma by referring to the medical books, prescription books, and other documents of the past dynasties, combined with relevant modern research materials, in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history, Huhuanglian has been used as its official name, and there are also aliases such as Gehu Luze, Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times, Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions, and also produced in China, mainly in Xizang. In ancient times, it was harvested and dried in early August of the lunar calendar, while in modern times, it is mostly harvested from July to September, with the best quality being those with thick and crispy rhizomes without impurities, and bitter taste. Throughout history, Picrorhizae Rhizoma was collected, washed, sliced, and dried before being used as a raw material for medicine, it has a bitter and cold taste, mainly used to treat bone steaming, hot flashes, infantile chancre fever, and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results, it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia, or the rhizomes of P. kurrooa, can be used in famous classical formulas containing this medicinal herb, which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements, the dried raw products are used as medicine.

Purpose:
Zinc finger protein 639 (ZNF639) is often found within the overlapping amplicon of PIK3CA, and previous studies suggest its involvement in the pathogenesis of esophageal and oral squamous cell carcinomas. However, its expression and significance in breast cancer remain uncharacterized.
Methods:
Immunohistochemical analysis of ZNF639 was performed using tissue microarrays.Functional studies, including colony formation, Transwell cell migration, and in vivo metastasis, were conducted on breast tumor cells with ZNF639 knockdown via small interfering RNA transfection.
Results:
Reduced ZNF639 immunoreactivity was observed in 82% of the breast cancer samples, independent of hormone receptor and human epidermal growth factor receptor 2 status. In multivariate Cox regression analyses, ZNF639 expression was associated with favorable survival outcomes, including recurrence-free survival (hazard ratio, 0.35; 95% confidence interval [CI], 0.14–0.89) and overall survival (hazard ratio, 0.41; 95% CI, 0.16– 1.05). ZNF639 knockdown increased clonogenicity, cell motility, and lung metastasis in NOD/ SCID mice. Following the ZNF639 knockdown, the expression of Snail1, vimentin, and C-C chemokine ligand 20 (CCL20) was upregulated, and the changes in cell phenotype mediated by ZNF639 were reversed by the subsequent knockdown of CCL20.
Conclusion
Low ZNF639 expression is a novel prognostic factor for recurrence-free survival in patients with breast cancer.

Objective: To investigate the effects of different storage temperatures and durations on the activities of coagulation factor Ⅷ (Factor Ⅷ, FⅧ) and coagulation factor Ⅸ (Factor Ⅸ, FⅨ) after whole blood collection, so as to provide data support for the optimal storage conditions. Methods: A total of 16 mL of whole blood was collected from each of the 20 healthy volunteers at our blood center and aliquoted into 8 sodium citrate anticoagulant tubes. Two tubes were immediately centrifuged for the measurement of FⅧ and FⅨ activity levels. The remaining 6 tubes of whole blood were respectively stored under room temperature and low-temperature conditions. At 2, 4, and 6 h, the whole blood samples were centrifuged and analyzed for FⅧ and FⅨ activity levels. The mean values of the two immediately tested tubes were used as the control group, while other tubes were designated as the experimental groups for comparison. Statistical analysis was performed using SPSS 26.0. Results: The activity of FⅧ in whole blood remained stable after 4 hours of storage at both room temperature and low temperature (116.53±25.95 vs 125.22±27.33, 109.77±23.23 vs 125.22±27.33) (P>0.05 for both). However, by 6 hours, FⅧ activity showed a statistically significant decline compared to the control group (108.65±22.92 vs 125.22±27.33, 100.46±20.19 vs 125.22±27.33) (P<0.05 for both), though the room temperature group results were closer to the control values. The activity of FⅨ in whole blood remained stable after 6 hours of storage under both conditions (97.14±19.48 vs 96.76±19.67, 97.10±17.45 vs 96.76±19.6) (P>0.05 for all comparisons). Conclusion: For whole blood samples after collection, storage at either room temperature or low temperature for up to 4 hours does not compromise the accuracy of test results. When stored for 6 hours, FⅨ activity remains stable, whereas FⅧ activity decreases significantly. Notably, FⅧ activity demonstrates better stability at room temperature than under low-temperature conditions within the 6-hour storage.
