In 2022, Hainan provincial government launched the project for the prevention and control of viral hepatitis with the goals of a hepatitis B screening rate of 90%, a diagnostic rate of 90%, and a treatment rate of 80% among people aged 18 years and above by the year 2025, and the main intervention measures include population-based prevention, case screening, antiviral therapy, and health management. As of December 31, 2024, a total of 6.875 million individuals in the general population had been screened for hepatitis B, with a screening rate of 95.6%. A total of 184 710 individuals with positive HBsAg were identified, among whom 156 772 were diagnosed through serological reexamination, resulting in a diagnostic rate of 84.9%. A total of 50 742 patients with chronic hepatitis B were identified, among whom 42 921 had hepatitis B-specific health records established for health management, with a file establishment rate of 84.6%. A total of 31 553 individuals received antiviral therapy, with a treatment rate of 62.2%. A total of 2.503 million individuals at a high risk of hepatitis C were screened, among whom 4 870 tested positive for HCV antibody and 3 858 underwent HCV RNA testing, resulting in a diagnostic rate of 79.2%, and 1 824 individuals with positive HCV RNA were identified, among whom 1 194 received antiviral therapy, with a treatment rate of 65.5%. In addition, 159 301 individuals with negative HBsAg and anti-HBs and an age of 20 — 40 years were inoculated with hepatitis B vaccine free of charge. Through the implementation of the project for the prevention and control of viral hepatitis, a large number of hepatitis patients have been identified, treated, and managed in the province within a short period of time, which significantly accelerates the efforts to eliminate the crisis of viral hepatitis.

BACKGROUND:Currently,spinal endoscopic technology has become the mainstream technology in minimally invasive spinal surgery.The specifications of the instruments for different operating systems are different,and the choice of specific surgical protocols needs to be combined with the actual situation of the patient and the choice of the clinical surgeon. OBJECTIVE:To compare the early efficacy of percutaneous endoscopic interlaminar discectomy for L5-S1 disc herniation under the iLESSYS Delta System and Endo-Surgi Plus System. METHODS:Totally 80 patients with L5-S1 disc herniation were treated with percutaneous endoscopic interlaminar discectomy.Patients were divided into two groups based on the endoscopic system used.Among them,37 cases received the iLESSYS Delta System(Delta group)and 43 cases received the Endo-Surgi Plus System(Plus group).Patient demographic characteristics,perioperative indicators,and complications were analyzed between the two groups.Clinical outcomes were quantified using back and leg visual analog scale scores,Oswestry Disability Index,and Japanese Orthopaedic Association scores at 1 day,1,3,and 6 months after surgery.Patient satisfaction was assessed according to modified MacNab criteria at final follow-up. RESULTS AND CONCLUSION:(1)The operative time and number of arthroplasties in the Plus group were less than those in the Delta group,and the differences were statistically significant(P<0.05).(2)Compared with the preoperative period,the visual analog scale scores,Oswestry Disability Index,and Japanese Orthopaedic Association scores of patients in both groups improved at all follow-up time points,and the difference was statistically significant(P<0.001).(3)There was no statistically significant difference in the comparison of pain visual analog scale scores,Oswestry Disability Index,and Japanese Orthopaedic Association scores of patients in the two groups(P>0.05).(4)At 6-month follow-up after surgery,the MacNab standard excellent and good rates in the Delta group and Plus group were 81%and 79%,respectively,with no significant difference(P=0.823).(5)The incidence of complications was 3%in the Delta group and 2%in the Plus group,but there was no significant difference between the two groups(P=0.914).(6)It is concluded that both iLESSYS Delta and Endo-Surgi Plus surgical systems achieved satisfactory early clinical results in the treatment of lumbar disc herniation,with Endo-Surgi Plus surgical moulding being more efficient and safer.

Grounded in the theory of "all marrows dominated by brain", this study explored the therapeutic mechanism of Zuogui Pills in modulating the oxytocin(OXT)/oxytocin receptor(OXTR) feed-forward loop in the treatment of postmenopausal osteoporosis(PMOP). A PMOP rat model was established using ovariectomy, and 70 Sprague-Dawley female rats were randomly divided into the following groups: sham operation group, model group, estradiol group(17β-estradiol, 0.05 mg·kg~(-1)·d~(-1)), Zuogui Pills low, medium, and high dose groups(0.2, 0.4, 0.8 g·kg~(-1)·d~(-1), respectively), and an antagonist group(atosiban 0.9 mg·kg~(-1)·d~(-1) + 17β-estradiol 0.05 mg·kg~(-1)·d~(-1) + Zuogui Pills 0.4 g·kg~(-1)·d~(-1)). After 12 weeks of model establishment, treatment was administered by gavage once daily for another 12 weeks, followed by sample collection. Enzyme-linked immunosorbent assay(ELISA) was used to measure serum levels of estrogen(E_2), OXT, tartrate-resistant acid phosphatase(TRACP-5b), and bone alkaline phosphatase(BALP). Histopathological changes in the left distal femur were observed through hematoxylin and eosin(HE) staining. Micro-computed tomography(micro-CT) was used to analyze the microstructure of the right distal femur. Western blot was employed to detect the expression levels of OXTR, small GTP-binding protein Ras, Raf1 proto-oncogene(Raf1), mitogen-activated protein kinase kinase 1/2(MEK1/2), and extracellular signal-regulated kinase 1/2(ERK1/2), and their phosphorylated forms in tibial tissues. Compared with the model group, the Zuogui Pills medium and high dose groups showed significantly increased levels of E_2, OXT, and BALP, with a notable decrease in TRACP-5b levels. Morphologically, the trabeculae in the left distal femur were more tightly arranged. The fibrous structure in the right distal femur was significantly improved in the Zuogui Pills high dose group. Additionally, the expression of OXTR, Ras, p-Raf1, p-MEK1/2, and p-ERK1/2 proteins in tibial tissues was significantly increased. The therapeutic effect of the Zuogui Pills high dose group was partially inhibited when an OXTR antagonist was administered. These findings suggest that Zuogui Pills can regulate the OXT/OXTR feed-forward loop, activate the phosphorylation of the downstream Ras/Raf1/MEK/ERK signaling pathway, and ultimately improve bone mineral density, thereby exerting therapeutic effects in PMOP.

Background With the progression of industrialization, an increasing number of emerging contaminants are entering aquatic environments, posing significant threats to the safety of drinking water. Therefore, establishing a system for identifying unknown hazardous factors and implementing safety warning mechanisms for drinking water is of paramount importance. Among these efforts, non-target screening plays a critical role, but its effectiveness is largely constrained by the scope of coverage of sample pre-treatment methods. Objective To integrate modern chromatography/mass spectrometry techniques with advanced data mining methods to develop a non-discriminatory sample pre-treatment method for comprehensive enrichment of unknown contaminants in drinking water, laying a technical foundation for the discovery and identification of unknown organic hazardous factors in drinking water. Methods A non-discriminatory pre-treatment method based on supramolecular and solid-phase extraction was developed. The final target compounds including 333 pesticides, 194 pharmaceuticals and personal care products (PPCPs), and 59 per- and polyfluoroalkyl substances (PFASs) were used for optimizing the pre-treatment method, confirming its coverage. The impacts of different eluents on the absolute recovery rates of target compounds were compared to select the conditions with the highest recovery for sample pre-treatment. The effects of different supramolecular solvents and salt concentrations on target compound recovery were also evaluated to determine the most suitable solvent and salt concentration. Results The solid-phase extraction elution solvents, supramolecular extraction solvents, and salt concentrations were optimized based on the target compound recovery rates. The optimal recovery conditions were achieved using 2 mL methanol, 2 mL methanol (containing 1% formic acid), 2 mL ethyl acetate, 2 mL dichloromethane, hexanediol supramolecular solvent, and 426 mg salt. The detection method developed based on these conditions showed a good linear relationship for all target compounds in the range of 0.1-100.0 ng·mL−1, with R² > 0.99. The method’s limit of detection ranged from 0.01 ng−1 to 0.95 ng−1, and 95% of target compounds were recovered in the range of 20%-120%, with relative standard deviation (RSD) less than 30%, indicating good precision. Conclusion The combined pre-treatment method of solid-phase extraction and supramolecular solvent extraction can effectively enrich contaminants in drinking water across low, medium, and high polarities, enabling broad-spectrum enrichment of diverse trace contaminants in drinking water. It provides technical support for broad-spectrum, high-throughput screening and identification of organic pollutants in drinking water, and also serves as a reference for establishing urban drinking water public safety warning systems.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

Plant-derived extracellular vesicles (PDEVs), describe a group of nanoparticles released by plants. These particles are characterized by a lipid bilayer structure containing various proteins, lipids, nucleic acids, and unique metabolites. Although the study on PDEVs is relatively new, having only been around for ten years, they have shown promising development prospects in both basic research and clinical transformation areas. Evidence suggests that PDEVs have excellent application prospects in regulating inflammation and treating tumors. Their distinctive, vesicle-mimicking architecture and stellar biocompatibility render them prime candidates for ferrying various anti-cancer agents, including RNA, proteins, and conventional chemotherapy drugs. Increasingly, studies have shown that PDEVs can be engineered as an innovative platform for combination cancer immunotherapy. Consequently, this paper provides an extensive summary of current developments in engineering methods and strategies for PDEVs in cancer treatment and combined cancer immune therapeutics. The essential characteristics of PDEVs, including the biogenesis process and components, as well as their anti-tumor activity and mechanism, are summarized. Finally, the in vivo safety of PDEVs as delivery vectors and the challenges of scale-up production and clinical transformation are discussed.

Background:
and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking.
Methods:
This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance.
Results:
Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal.
Conclusions
The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Background:
s/Aims: Distal pancreatectomy with splenectomy (DPS) is a common surgical procedure for pancreatic body cancer.However, spleen-preserving distal pancreatectomy (SPDP) utilizing the Warshaw technique (WT) in malignancies is generally not favored due to concerns about inadequate resection. This study aims to assess the feasibility and oncologic outcomes of employing SPDP with WT in pancreatic body cancer.
Methods:
We conducted a retrospective analysis comparing 21 SPDP patients with 63 DPS patients matched by propensity score from January 2018 to November 2022. Clinical outcomes and follow-up data were analyzed using R.
Results:
Both groups exhibited similar demographic, intraoperative, and pathological characteristics, with the exception of a reduced number of total lymph nodes (p = 0.006) in the SPDP group. There were no significant differences in the rates of postoperative complications, recurrence, or metastasis. Local recurrence predominantly occurred in the central region as opposed to the spleen region.There were no cases of isolated recurrences in the splenic region. Median overall survival and recurrence-free survival times were 51.5 months for SPDP vs 30.5 months for DPS and 18.7 months vs 16.8 months, respectively (p > 0.05). The incidence of partial splenic infarction and left-side portal hypertension in the SPDP group was 28.6% (6/21) and 9.5% (2/21), respectively, without necessitating splenic abscess puncture, splenectomy, or causing bleeding from perigastric varices.
Conclusions
SPDP did not negatively impact local recurrence or survival rates in selected pancreatic body cancer patients. Further studies are necessary for validation.
