OBJECTIVE To compare the efficacy and safety of evolocumab and probucol in patients with ultra-high-risk atherosclerotic cardiovascular disease （ASCVD） following percutaneous coronary intervention （PCI）. METHODS A retrospective analysis was conducted on 156 ultra-high-risk ASCVD patients who underwent PCI in our institution between January 1， 2023 and December 31， 2024. According to the lipid-lowering regimen， the patients were categorized into evolocumab group （ n ＝86） and probucol group （ n ＝70）. Changes in lipid parameters [total cholesterol （TC）， low-density lipoprot ein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， triglycerides， lipoprotein （a）， and lipid goal achievement rate ] ， inflammatory markers [interleukin-6 （IL-6） and C-reactive protein （CRP） ] ， and cardiac function indices （left ventricular ejection fraction， left ventricular end-systolic diameter， left ventricular end-diastolic diameter， and N-terminal pro-B-type natriuretic peptide） were compared between two groups at baseline and after 6 months of treatment. The incidence of adverse clinical events during treatment， including acute myocardial infarction， in-stent restenosis， acute heart failure， cerebral hemorrhage， and stroke， was also evaluated. RESULTS No statistically significant differences were observed between the two groups at baseline （ P ＞0.05）. After 6 months of treatment， both groups demonstrated significant improvements in lipid profiles （except HDL-C） and inflammatory markers compared to those at baseline （ P ＜0.05）. The evolocumab group exhibited greater reductions in TC， LDL-C， IL-6， and CRP， along with a higher lipid target achievement rate， compared with the probucol group （ P ＜0.05）. There were no statistically significant differences in the cardiac function-related indicators before and after treatment between the two groups， nor in the incidence of adverse events during the treatment （ P ＞0.05）. CONCLUSIONS For ultra-high-risk ASCVD patients after PCI， both of the above treatment options are associated with improvements in blood lipid and inflammatory response， with good safety during short-term follow-up. Evolocumab shows superior efficacy in TC， LDL-C and inflammatory markers reduction and lipid target achievement， compared to probucol.

Objective: To improve the efficiency of patient treatment in routine, emergency, and mass casualty scenarios (both peacetime and wartime), eliminate reliance on blood type compatibility, and promote the productization of platelet-rich plasma (PRP), this study investigated the optimal mixing ratio for developing a universal PRP formulation. Methods: PRP was prepared from donors with blood types O, A, B, and AB. Samples were mixed in varying proportions, and the optimal ratio was determined based on the trend of anti-A and anti-B antibody titers in the mixed PRP. Concentrations of the growth factors PDGF-AA, PDGF-BB, EGF, TGF-β1, and VEGF were measured by enzyme-linked immunosorbent assay (ELISA) before and after mixing. Results: A mixing ratio of A∶B∶AB=6∶2.5∶24 resulted in no detectable agglutination with either A or B cells in the microcolumn gel system, indicating the absence of immunological reactivity and confirming universal compatibility. Importantly, the levels of all measured growth factors remained unchanged following mixing, suggesting preservation of biological activity. Conclusion: These findings suggest that universal PRP can be prepared by neutralizing blood type antibodies through antigen-antibody reactions.

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.

AIM: To explore the application effect of eyelid margin incision combined with floating bridge technique in the treatment of ptosis patients, and to analyze its effects on the margin reflex distance 1(MRD1)and the aesthetic effect of the eyes. METHODS:Prospective study. This study enrolled patients with blepharoptosis treated at the Department of Ophthalmology of the hospital between January 2023 and July 2025, who were assigned to either an observation group or a control group. The patients in the control group received levator aponeurosis shortening surgery through conventional double-eyelid incision, while the patients in the observation group underwent levator aponeurosis shortening surgery using the eyelid margin incision combined with floating bridge technique. Subsequently, the surgical-related indicators,the correction effect of ptosis, the aesthetic effect, the ocular function indicators, the postoperative complication occurrence rate, and recurrence rate were compared and analyzed between two groups.RESULTS:A total of 100 patients(100 eyes)with blepharoptosis were enrolled in this study, with 50 patients(50 eyes)in the observation group and 50 patients(50 eyes)in the control group. The observation group had a mean age of 27.33±5.32 y, including 20 males and 30 females. The control group had a mean age of 27.64±4.66 y, including 24 males and 26 females. Compared with the control group, the operative time of the observation group was longer, the postoperative swelling resolution time and natural recovery time were shorter,and the correction rate was higher(P<0.05). Three months after the surgery, the VSS score and POSAS score of the observation group were lower than those of the control group, while the scores for eyelid curvature, symmetry of eyelid height, and the PFH, MRD1, palpebral fissure size, and upper eyelid levator muscle strength were all higher than those of the control group(all P<0.05). However, there was no significant difference in postoperative complication occurrence rate and recurrence rate between two groups(all P>0.05).CONCLUSION:The combined use of eyelid margin incision and floating bridge technique for treating ptosis results in slightly longer operation time, but it can shorten the postoperative recovery period, effectively ameliorate the MRD1 and ocular function of patients, and enhance the correction effect and aesthetic quality of the eyes. In addition, it has a low incidence of complications and guaranteed safety.

Objective To explore the risk factors for postoperative pneumonia (POP) following esophagectomy for esophageal cancer, and to identify potential clinical indicators for predicting POP. Methods A retrospective analysis was conducted on the clinical data of patients with esophageal cancer who underwent esophagectomy at the Department of Thoracic Surgery, West China Hospital of Sichuan University from 2017 to 2021. Perioperative clinical indicators were collected to analyze the risk factors for the occurrence of POP. Patients were divided into a POP group and a non-POP group according to whether POP occurred. Results A total of 613 patients with esophageal cancer were included, comprising 472 males and 141 females, with a median age of 62.0 (53.0, 67.0) years. Among them, 51 patients were in the POP group, and 562 patients were in the non-POP group. Multivariate logistic regression analysis showed that the forced expiratory volume in 1 second percentage of predicted (FEV1%) [OR=0.958, 95%CI (0.943, 0.973), P<0.001], systemic immune-inflammation index (SII) [OR=1.001, 95%CI (1.000, 1.002), P=0.007], and prognostic nutritional index (PNI) [OR=0.869, 95% CI (0.813, 0.928), P<0.001] were independent risk factors for POP. Receiver operating characteristic (ROC) curve analysis combining FEV1%, SII, and PNI demonstrated that the area under the curve (AUC) for predicting POP was 0.826 [95%CI (0.793, 0.855), cut-off value: 0.08, sensitivity: 80.3%, specificity: 72.4%, Youden index: 0.528, P<0.001]. Cross-validation confirmed that the combined indicators had the highest predictive efficacy, which was significantly superior to that of any single indicator alone. Conclusion Preoperative levels of FEV1%, SII, and PNI are closely associated with the occurrence of POP following surgery for esophageal cancer. The combined application of FEV1%, SII, and PNI demonstrates good predictive efficacy for the occurrence of POP.

Liver cancer imposes a substantial global disease burden.Hepatocellular carcinoma(HCC),as the primary pathological type of primary liver cancer,accounts for approximately 90％of all cases.As a minimally invasive treatment,thermal ablation causes minimal impact on liver function and trauma,serving as the first-line treatment option for early-stage HCC patients unsuit-able for surgical resection.However,clinical data indicate that 5-year recurrence rate of HCC pa-tients after thermal ablation treatment is as high as 50％～70％,and incomplete ablation remains a core factor leading to recurrence.Therefore,exploring and optimizing complete ablation strategies has become a critical direction for improving the efficacy of thermal ablation in HCC and enhanc-ing long-term survival rates of patients.This paper systematically reviews the current applications of thermal ablation in HCC treatment and focuses on discussing key technologies and strategies for achieving complete ablation,with the aim of providing theoretical foundations and technical refer-ences for improving the complete ablation rate of thermal ablation in clinical practice and formu-lating personalized diagnosis and treatment plans.

OBJECTIVE To investigate the current status of bloodborne occupational exposures among healthcare workers in a three-A specialized hospital of Shanghai so as to provide bases for formulating prevention measures for occupational exposures.METHODS A questionnaires titled'Survey of bloodborne occupational exposures among healthcare workers'were clinically distributed to Eye &ENT Hospital of Fudan University through'Wenjuanxing platform'from Feb.2024 to Apr.2024.The content of the questionnaire included four parts:the baseline data questionnaire,incidence of occupational exposures,awareness of knowledge about occupational exposures,and preventive behaviors regarding occupational exposures.RESULTS A total of 995 valid questionnaires were collect-ed in the survey,the result of the survey showed that the incidence of bloodborne occupational exposures was 10.65％.The clinicians and doctors engaging in advanced studies were at high risk of the occupational exposures especially when they were busy with work.The result of the survey indicated that the rate of missing report was 71.33％,the implementation rate of monitoring was only 48.11％after the exposures,of which the major cau-ses included the health care workers'insufficient attention to the exposure events,flaws in prevention and control of occupational exposures and some personnels'poor awareness of reporting process and requirements for monito-ring.Although the awareness rate of emergency processing exceeded 90％,the awareness rate of the knowledge a-bout prophylactic use of antibiotics and prevention of needlestick injuries,and the preparations before diagnosis and treatment,standardized operations and use of protective articles still needed to be improved.CONCLUSIONS The survey reveals that the health care workers pay less attention to the risk of infections,and the prevention of occupational exposure needs to be improved.It is of great importance to raise the awareness of prevention and en-hance the systematic training for occupational exposure.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To analyze the association of sedentary time and physical activity with the risk of developing chronic obstructive pulmonary disease (COPD) in non-smoking women aged 40 years and above in Songjiang District, Shanghai.Methods:Based on a natural population-based cohort in Songjiang, a total of 18 707 non-smoking women who were aged 40 years and above and without COPD at baseline survey were enrolled in the study. Cox proportional risk regression model was used to analyze the associations of the duration of sedentary behavior, physical activity with the risk for COPD at baseline survey, and the hazard ratio ( HR) of risk for COPD and its 95% CI were calculated. Stratified analyses were performed based on age, BMI, history of respiratory diseases and so on. Sensitivity analyses were conducted by excluding the cases diagnosed with COPD within one year after the baseline survey. Results:As of March 31, 2024, a total of 691 new COPD cases had been recorded after a median follow-up time of 6.96 years with an incidence density of 53.22 per 10 000 person-years. After adjusting for relevant confounders, in the tertile subgroups of sedentary time, the risk for COPD reduced by 17% in the short sedentary time group compared with the long sedentary time group ( HR=0.83,95% CI:0.70-0.99). Compared with the low physical activity level and long sedentary time group, the risk for COPD reduced by 24% in the high physical activity level and short sedentary time group ( HR=0.76, 95% CI: 0.61-0.95) and by 23% in the low physical activity level and short sedentary time group ( HR=0.77, 95% CI: 0.60-0.97). Compared with the non-physical exercise and long sedentary time group, the risk for COPD reduced by 28% in the non-physical exercise and short sedentary time group ( HR=0.72, 95% CI: 0.60-0.87). These associations remained when the cases diagnosed with COPD within one year of the baseline survey were excluded. Conclusions:Increasing physical activity and reducing sedentary time have beneficial effects to prevent COPD in non-smoking women, and reducing sedentary time alone may also reduce the risk for COPD if increasing physical exercise or other physical activity is not possible.

Objective:To compare the infection status of severe fever with thrombocytopenia syndrome (SFTS) between the non-endemic area (Yixian county, Huangshan city) and the endemic area (Qianshan city, Anqing city) in Anhui province, and to explore the possibility of Yixian county being a natural focus of SFTS, thereby providing a scientific basis for the formulation of prevention and control strategies.Methods:In Xidi town, Yixian county, and Shuihou town, Qianshan city, one administrative village with the highest number of reported cases in the past three years was selected as the study village in each area, along with one control village with no reported cases. The study investigated the total antibody positivity rates of SFTS virus (SFTSV) in natural populations and host animals, as well as the density and virus-carrying rate of the vector ticks. Differences in total antibody positivity rates between the two regions were compared.Results:The total SFTSV antibody positivity rates in the natural population and host animals in the surveyed villages (control villages) of Qianshan city and Yi county were 8.7% and 8.0% (3.3%, 4.1%) and 0.0%, 9.1% (50.0%, 66.7%), respectively. There was no statistically significant difference in the infection rates of the natural population and host animals between the surveyed villages (control villages) in different endemic regions (all P>0.05). In the surveyed villages of Qianshan city and Yi county, the free-living tick densities were 1.4 ticks/hour per flag and 1.7 ticks/hour per flag, respectively; the parasitic tick densities were 0.4 ticks/host and 2.5 ticks/host, respectively; the tick infestation rates were 33.3% and 35.3%, respectively; and the tick density indices were 1.3 ticks/host and 7.2 ticks/host, respectively. Conclusions:The natural populations and host animals in some areas of Yixian county exhibit high SFTSV infection rates, and the tick density is also high, suggesting that the region may have become a natural focus of SFTS. Therefore, it is necessary to further strengthen capabilities in surveillance, diagnosis, and clinical treatment to address the potential risk of SFTS outbreaks.
