ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Objective To investigate the effects of low, mid, and high flux smoothness modes on plan quality, treatment efficiency, equipment loss, and clinical economic benefits in fixed-field intensity-modulated radiotherapy for cervical cancer, and establish a decision-making model for parameter optimization and economic benefits. Methods Fifteen patients with cervical cancer undergoing radiotherapy were selected. Using the Monaco system and adjusting only the flux smoothness parameter, low, mid, and high plans were designed for each patient. Dosimetric differences were compared for the target volume (D2, D98, Dmean, homogeneity index, conformity index) and organs at risk (small intestine, rectum, colon, bladder, femoral head). The number of segments, monitor units, and their correlations with treatment efficiency and equipment loss were analyzed, as well as the potential impact on clinical costs. Results There were statistically significant differences in the three groups' planned target areas D2, D98, Dmean, CI, HI, and the dose parameters of organs at risk (P<0.001), but the absolute differences were all lower than the clinical tolerance limits in the ICRU 83 report (±3% – ±5%), with an effect size d<0.5 (except for the small intestine with d = 0.51). There was no clinical significance. Compared with the mid mode, the high mode had a 13.3% reduction in the number of subfields (effect size d = 0.85), a 11.6% reduction in machine jumps (d = 1.0), and a 13.0% reduction in treatment time. Based on the mid mode, the relative loss rate of the accelerating tube in the high mode was 11.6%, the theoretical risk change rate of equipment failure was 12.7%, and the accelerating tube lifespan was extended by approximately 1.2 years. Comprehensive economic benefits: Calculated based on 1,200 treatments per year, the annual cost savings are approximately 920,000 yuan. Conclusion Adoption of the high flux smoothness mode in fixed-field intensity-modulated radiotherapy for cervical cancer using the Monaco system can significantly enhance treatment efficiency and reduce operating costs while ensuring dosimetric quality. It is recommended for routine clinical use.

ObjectiveTo systematically characterize the in vitro chemical constituents of Entada phaseoloides and its absorbed prototype compounds and metabolites in a neuropathic pain (NP) model, thereby elucidating the potential pharmacological material basis underlying its analgesic activity. MethodsUltra-high-performance liquid chromatography coupled with quadrupole-Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) was used to analyze the constituents of the 80% methanol extract of E. phaseoloides. Thirty-six mice were divided into a blank group, low-, medium-, and high-dose E. phaseoloides extract groups (25, 50, and 100 mg·kg-1, respectively), an aspirin group (400 mg·kg-1), and a morphine group (10 mg·kg-1), with six mice in each group. The tail-flick threshold was measured. Twenty-four mice were randomly divided into a blank group and low-, medium-, and high-dose E. phaseoloides extract groups (25, 50, and 100 mg·kg-1, respectively), with six mice in each group, and motor coordination was evaluated. A spinal nerve ligation (SNL) model was established in mice. Twenty-four mice were randomly divided into a sham-operated (Sham) group, an SNL group, an SNL + E. phaseoloides extract group (750 mg·kg-1), and an SNL + pregabalin group (20 mg·kg-1), with 6 mice in each group. Mechanical allodynia and thermal hyperalgesia were evaluated. Behavioral assessments were combined to determine the optimal onset time of the analgesic effect, and plasma samples were collected at this time point. Absorbed components and metabolites were systematically identified based on accurate mass, MS/MS fragmentation patterns, retention time, and comparisons with literature data and reference standards. Meanwhile, network pharmacology, target similarity analysis, and molecular docking validation were integrated to evaluate the potential effects of absorbed components on disease intervention. ResultsCompared with the blank group, the high-dose E. phaseoloides extract group and morphine group showed significantly increased pain response thresholds (P<0.01), without affecting motor coordination in normal mice. Compared with the Sham group, the SNL group exhibited significantly decreased thresholds for mechanical allodynia and thermal hyperalgesia (P<0.01). Compared with the SNL group, the SNL + E. phaseoloides extract group and SNL + pregabalin group showed significantly increased thresholds for mechanical allodynia and thermal hyperalgesia (P<0.01). The analgesic effect of E. phaseoloides was most significant at 2 h after administration. A total of 70 constituents were identified in vitro, and 22 prototype compounds and 29 metabolites were detected in plasma. The targets of the absorbed components were mainly enriched in biological processes associated with pain signal perception and transmission and showed a high degree of overlap with disease genes related to neuropathic pain. In addition, multiple components exhibited strong binding energies with core pain-related targets. Based on integrated analysis of in vitro content, plasma exposure levels, and target associations, ketanthamide A-β-D-pyranoside and ketengzide were identified as the most representative pharmacologically active substances responsible for the analgesic effect. ConclusionThis study systematically elucidates the material basis of E. phaseoloides intervention in neuropathic pain from three aspects, including chemical constituent characteristics, in vivo behavioral characteristics, and potential targets, providing important theoretical foundations and experimental support for further studies on its pharmacological mechanism and analgesic drug development.

Hyperlipidemia is a common metabolic disorder driven by dysregulated lipid metabolism, whose pathological progression involves multifaceted interactions across various signaling pathways, including disrupted cholesterol homeostasis, insulin resistance, chronic inflammation, and oxidative stress. Although existing clinical medications such as statins can effectively reduce low-density lipoprotein cholesterol through single-target inhibition, significant limitations remain in comprehensively improving reverse cholesterol transport, metabolic inflammation, and coordinated regulation of glucose and lipid metabolism. Curcumin, the primary polyphenolic active compound derived from the traditional medicinal herb turmeric, exhibits multi-dimensional pharmacological effects including modulation of lipid metabolism, improvement of insulin sensitivity, suppression of inflammatory responses, and enhancement of antioxidant defense. This review systematically integrates the multi-target regulatory network of curcumin, elucidating its key mechanisms: Balancing the low density lipoprotein receptor/proprotein convertase subtilisin/kexin type 9 (LDLR/PCSK9) signaling pathway to promote reverse cholesterol transport, activating peroxisome proliferator-activated receptor α/γ (PPARα/γ) signaling pathways to coordinate glucolipid metabolic homeostasis, remodeling the gut microbiota-bile acid axis, inhibiting nuclear factor kappa-B (NF-κB)-mediated inflammatory responses, and activating the nuclear factor erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE) antioxidant signaling pathway. Furthermore, supported by clinical research data, the review validates curcumin's therapeutic potential in reducing total cholesterol (TC) and triglyceride (TG) levels, increasing high-density lipoprotein cholesterol (HDL-C), as well as improving vascular endothelial function and insulin sensitivity. The study highlights the multi-target regulatory properties of curcumin and discusses future clinical applications based on nano-delivery systems and personalized treatment strategies, providing a theoretical basis and novel insights for the prevention and treatment of hyperlipidemia and related metabolic disorders.

To investigate the clinical application value of indocyanine green(ICG) fluorescence-guided thoracoscopic lung lesion resection under the diagnosis related group(DRG) payment system, and to provide reference for the management of new medical technologies in healthcare institutions. Discharged patients who underwent thoracoscopic segmentectomy and/or wedge resection at Peking Union Medical College Hospital from January 1, 2016 to May 31, 2024 were enrolled. Patients who received ICG fluorescence guidance were assigned to new technology group, while those who did not receive ICG fluorescence guidance were assigned to control group. Operative time, length of stay, cost consumption index, time consumption index, duration of ventilator use, total hospitalization cost, and 10 representative cost items were compared between the two groups. Propensity score matching(PSM) was further used to analyze the changes in these indicators after controlling for confounding factors including age, sex, DRG code, and surgical type. A total of 7999 patients who met the inclusion and exclusion criteria were enrolled, including 1392 patients(17.4%) in the new technology group and 6607 patients(82.6%) in the control group. Compared with the control group, the new technology group showed significantly shorter operative time and length of stay, and significant reductions in time consumption index, consultation and diagnostic fees, nursing fees, therapeutic medical material fees, bed fees, oxygen therapy fees, antibiotic fees, and albumin product fees, while the cost consumption index, total hospitalization cost, surgical fees, and surgical medical material fees were significantly increased(all ICG fluorescence-guided thoracoscopic lung lesion resection can significantly improve medical efficiency, optimize cost structure, and reduce perioperative supportive resource consumption. However, its clinical benefits vary significantly among patients with different surgical types or different DRG groups, so clinicians are advised to strengthen preoperative precise evaluation.

Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

BACKGROUND:Osteoporotic vertebral fractures are the most common complication in patients with osteoporosis.As a new imaging technique,spine magnetic resonance imaging(MRI)is much more sensitive than X-ray film in the diagnosis of osteoporotic vertebral fractures.However,total spine MRI is costly and takes a long time to scan.Therefore,there is no consensus on whether all patients with osteoporotic vertebral fractures need to undergo total spine MRI scan and which patients need to undergo total spine MRI. OBJECTIVE:To analyze the distribution characteristics of vertebral fractures and explore their clinical significance by observing the whole spine MRI data of osteoporotic vertebral fractures patients. METHODS:Data of cases and MRI images of all patients diagnosed with fresh osteoporotic vertebral fractures who visited the Department of Orthopedics,Affiliated Hospital of Southwest Medical University from August 2018 to September 2022 were retrospectively analyzed.903 patients were included in the study based on inclusion and exclusion criteria.General information(age,gender,and body mass index),medical history characteristics(duration of illness,history of trauma surgery,percussion pain area,and pain score)were collected.The characteristics of vertebral fractures were analyzed through whole spine magnetic resonance imaging.Firstly,based on the number of vertebral fractures in patients,they were divided into the single vertebral fracture group(484 cases)and the multi-vertebral fracture group(419 cases),and the differences were analyzed between the two groups.Then,based on whether the farthest interval between the fractured vertebrae was greater than or equal to 5,the multi vertebral fracture group was further divided into two subgroups.Among them,Group A(the farthest interval between the fractured vertebrae was less than 5)contained 306 cases;Group B(with the farthest interval between fractured vertebral bodies greater than 5)included 113 cases.The differences were analyzed between two subgroups. RESULTS AND CONCLUSION:(1)Among 903 patients,419 patients(46.4%)had more than two fractured vertebrae.There were 654 patients(72.4%)with thoracolumbar fractures,and 54 patients(6%)with fractures in the thoracic plus lumbar region and the entire thoracic to lumbar region.In group B,96.5%of patients had multiregional percussion pain.(2)Compared with the patients in the single vertebral fracture group and the multi-vertebral fracture group,there were significant differences in bone mineral density,whether the medical history was greater than or equal to 1 month,the history of low energy injury,and the distribution and number of axial percussion pain areas in the spine during physical examination between the two groups(P<0.05).Age,gender,body mass index,whether there was underlying disease,pain visual analog scale score,whether there was a history of elderly thoracolumbar fracture,and whether there was a history of thoracolumbar surgery,and the number of fractured vertebrae had no statistical significance(P>0.05).(3)There were statistically significant differences between the Groups A and B in bone mineral density,the distribution and quantity of percussion pain area,and the history of low energy injury(P<0.05).There were no significant differences in age,gender,history of old fractures,visual analog scale score,body mass index,whether the medical history was longer than or equal to 1 month,history of underlying diseases,and history of thoracolumbar surgery between the two groups(P>0.05).(4)Patients with multiple low-energy trauma history,history of more than 1 month,multiple percussion pain,and the lower bone mineral density should be alert to the occurrence of multiple vertebral fracture and jump fracture.We recommend the whole spinal MRI for these patients.

ObjectiveTo explore the mechanism of Jiebiao Qingli decoction (JQD) in treating pneumonia caused by influenza A virus (IAV) infection. MethodsA total of 132 Balb/c mice were randomly assigned into normal control (NC), model control (IAV), oseltamivir (OSV, 37.5 mg·kg-1), and high-, medium-, low-dose JQD (H-, M-, and L-JQD: 6.05, 3.02, and 1.51 g·kg-1, respectively) groups. The NC group was treated with normal saline nasal drops, and the other groups were intranasally inoculated with A/Brisbane/02/2018 (H1N1) [pdm09-like virus (H1N1)] for the modeling of IAV infection. Two hours post-modeling, the NC and IAV groups were administrated with normal saline by gavage, while other groups received corresponding drugs for 7 d. The body mass, survival status, and deaths of mice were recorded daily during the administration of the drugs. On days 3 and 7, the lung index was measured for mice in each group. Pathological changes in the lung tissue were observed via hematoxylin-eosin staining. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was conducted to measure the viral load (IAV-M) and the mRNA levels of Toll-like receptor 7 (TLR7), p38 mitogen-activated protein kinase (p38 MAPK), and nuclear factor-kappa B (NF-κB) in the lung tissue. Western blot was employed to measure the protein levels of p38 MAPK and NF-κB. Enzyme-linked immunosorbent assay was used to quantify serum levels of interleukin-2 (IL-2), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). ResultsCompared with the NC group, the IAV group showed reduced survival quality and survival days (P<0.01), lung congestion, inflammatory cell infiltration, elevated lung index (P<0.01), increased viral load (P<0.01), upregulated TLR7, p38 MAPK, and NF-κB levels (P<0.05, P<0.01), decreased IL-2 level (P<0.01), and elevated IL-6 and TNF-α levels (P<0.01). Compared with the IAV group, H-JQD prolonged survival days (P<0.05). All JQD groups alleviated pathological changes in the lung tissue and reduced the lung index (P<0.01). M-JQD and H-JQD decreased the viral load (P<0.01). H-JQD downregulated the mRNA levels of TLR7, p38 MAPK, and NF-κB (P<0.05, P<0.01) and the protein levels of p38 MAPK and NF-κB (P<0.01), increased the serum IL-2 level (P<0.01), and lowered the IL-6 and TNF-α levels (P<0.05, P<0.01). M-JQD downregulated the mRNA level of NF-κB (P<0.01) and the protein level of p38 MAPK (P<0.05), elevated the IL-2 level (P<0.01), and lowered the TNF-α level (P<0.01). ConclusionM- and H-JQD can prevent and control IAV infection-induced pneumonia dose-dependently by inhibiting the TLR7/MAPK/NF-κB signaling pathway, increasing IL-2, and reducing excessive secretion of IL-6 and TNF-α.
