The surgical management of empyema (excluding those caused by mycobacterium tuberculosis and non-tuberculous mycobacteria) is rapidly evolving towards minimally invasive, precise, and stepwise approaches. The traditional three-stage classification (exudative, fibrinopurulent, and organizing) has limitations in guiding dynamic clinical decision-making. For the first time, this consensus explicitly identifies two critical junctures in the pathological progression of empyema: "early transformation" (stage Ⅰ to Ⅱ) and "late transformation" (stage Ⅱ to Ⅲ), and thereby constructs a corresponding "identification-early warning-intervention" stepwise therapeutic framework. The consensus emphasizes that proactive debridement via video-assisted thoracoscopic surgery should be performed during the early transformation phase to halt disease progression. Conversely, during the late transformation phase, therapeutic goals should be rationally adjusted to prioritize adequate drainage, avoiding futile pleural decortication. Moreover, the consensus underscores the pivotal role of precise perioperative etiological diagnosis (e.g. metagenomic nest-generation sequencing) and standardized anti-infective therapy. Integrating practical experiences from multiple thoracic surgery centers in China and relevant evidence-based literature, this consensus formulates recommendations on the precise definitions of staging, surgical indications for each phase, key technical points, perioperative management, and training systems. It aims to promote the standardized and individualized surgical management of empyema, ultimately optimizing patient prognosis.

AIM:To assess the influence of preoperative lacrimal passage probing and dilation on the therapeutic effectiveness of nasolacrimal silicone intubation in cases of incomplete primary acquired nasolacrimal duct obstruction(PANDO).METHODS: A retrospective case-control clinical study was conducted. The study included patients with incomplete PANDO who underwent nasolacrimal silicone intubation at the hospital between October 2022 and October 2024. Participants were categorized into two groups based on their receipt of nasolacrimal duct probing and dilation prior to intubation. Group A consisted of patients who had undergone one or more sessions of nasolacrimal duct probing and dilation before nasolacrimal silicone intubation, while Group B included patients who did not receive nasolacrimal duct probing and dilation before intubation. All patients had their nasolacrimal silicone tubes removed 3 mo postoperatively and were monitored for 6 mo following tube removal to evaluate surgical success rates.RESULTS: A total of 136 patients(152 eyes)completed the six-month follow-up period. The overall surgical success rate for both groups was 72.4%(110/152 eyes).Group A included 22 males and 36 females, mean age 58.09±11.07 y, and achieved a success rate of 82.8%(53/64 eyes), while Group B included 27 males and 51 females, mean age 59.35±8.84 y and attained a success rate of 64.8%(57/88 eyes). The difference in surgical success rates between the two groups was statistically significant(P=0.014). Furthermore, Group A achieved a complete success rate of 67.2%(43/64 eyes), compared to 47.7%(42/88 eyes)in Group B, with this difference also reaching statistical significance(P=0.017). No serious postoperative complications were observed in either group.CONCLUSION: Nasolacrimal silicone intubation is a safe and effective intervention for incomplete PANDO, with preoperative nasolacrimal duct probing and dilation potentially enhancing therapeutic outcomes.

[摘 要] 目的：探讨肽基精氨酸脱亚胺酶1（PADI1）对肾透明细胞癌（ccRCC）细胞迁移、增殖、侵袭等生物学行为的影响及相关分子机制。方法：首先，利用转录组测序筛选肾癌组织与癌旁组织之间的差异表达基因，并通过GEPIA、TIMER2.0等数据库分析其差异表达水平。选取2024至2025年河北医科大学第四医院泌尿外科术中留存的59例ccRCC患者的组织标本，用RT-qPCR法、免疫组化SP法检测肾癌组织及癌旁组织中PADI1的表达水平，分析其与各临床参数之间的关系。通过划痕愈合、CCK-8、克隆形成及Transwell实验评估PADI1对ccRCC细胞迁移、增殖和侵袭能力的影响，用流式细胞术检测PADI1对细胞周期的影响，并采用WB法检测A498细胞转染si-PADI1后角质化包膜（CE）形成通路及EMT相关蛋白表达的变化。结果：在ccRCC组织中PADI1的相对表达量显著高于癌旁正常组织（P < 0.01），并与患者年龄、淋巴结转移、远处转移及临床分期相关（P < 0.05）。A498和ACHN细胞中转染si-PADI1，可以有效地下调PADI1 mRNA和蛋白表达水平（P < 0.05）；而转染过表达质粒则能够显著上调其表达（P < 0.05），敲低PADI1能够显著抑制其迁移（P < 0.05）、增殖（P < 0.05）与侵袭能力（P < 0.001），而过表达则增强其迁移（P < 0.05）、增殖（P < 0.05）与侵袭能力（P < 0.001），但对细胞周期影响不显著。在A498细胞中，WB实验结果显示PADI1表达能够改变EMT及CE通路相关蛋白表达水平。结论：PADI1在ccRCC中高表达且与ccRCC患者年龄及其淋巴结转移、远处转移、临床分期有关联，其表达水平升高能够影响CE形成通路及加速EMT进程，并增强ccRCC细胞的迁移、增殖、侵袭能力。

OBJECTIVE To establish an integrated central pharmacy management model combining the inpatient pharmacy and the pharmacy intravenous admixture service （PIVAS）， and to evaluate its effectiveness and economic value in terms of operational cost composition， dispensing output， and dispensing efficiency.METHODS Through spatial integration， flexible staff scheduling， the application of intelligent equipment， and a dual prescription review system， the inpatient pharmacy and PIVAS were integrated， and an integrated management model was implemented. Operational data from the Fourth Affiliated Hospital of Soochow University （hereinafter referred to as “our hospital”） in 2023 were selected for analysis， with national median data and data from another hospital in the same region that still implemented a separate management model for the inpatient pharmacy and PIVAS serving as controls. The activity-based costing method was used to calculate operating costs. Dispensing output， dispensing efficiency， and unit activity cost were compared among the three. Cost-benefit analysis was further conducted by calculating the net benefit （NB） and the incremental cost-effectiveness ratio （ICER） for economic evaluation.RESULTS Under the integrated central management model， the total operational cost of our hospital’s central pharmacy was 3.968 3 million yuan， representing an 11.80% reduction compared with the external hospital’s pharmacy （4.499 0 million yuan）， with consumable costs and labor costs decreasing by 38.73% and 10.99%， respectively. The total prescription dispensing volume （3.613 4 million orders） was 43.58% higher than that of the external hospital’s pharmacy （2.516 7 million orders）. The daily dispensing volume per capita reached 471.41 medication orders， 3.5 times that of the external hospital’s pharmacy （135.20 medication orders）. The unit activity cost was 1.10 yuan， showing a 38.55% decrease relative to the external hospital’s pharmacy （1.79 yuan）. The NB was 755 200 yuan， and the ICER was －2.36. In terms of PIVAS operations， the daily dispensing volume per capita for general infusions （including antibacterial drugs） in our hospital was 50.83 sets， higher than the national PIVAS median （49.11 sets） and the external hospital pharmacy （36.14 sets）； the daily dispensing volume per capita for hazardous drugs was 0.86 sets， higher than the national median （0.70 sets） and the external hospital pharmacy （0.16 sets）.CONCLUSIONS The integrated central pharmacy management model established by our hospital achieved reduced operational costs and enhanced staff efficiency despite growing service volumes. Integrating the functions of both the inpatient pharmacy and the PIVAS， this model outperformed national medians and peer hospitals in dispensing output， dispensing efficiency， unit activity cost control， and economic evaluation， and surpassed the national median specifically in PIVAS dispensing efficiency.

Objective: To evaluate the risk of donation-related adverse reactions, donation behavior, and contributions to the blood supply among donors aged 56-65 years following extension of the upper age limit for voluntary blood donation, and to provide real-world evidence for optimizing blood donation age policies in China. Methods: A multicenter retrospective cohort was established using blood donation databases from Hainan, Shenzhen, and Jiangxi. A total of 1 180 767 donors contributing 2 020 407 whole-blood and apheresis donations were included. Donations were classified by donor age at each donation into the 18-55-year and 56-65-year groups. Generalized estimating equation (GEE) models were used to compare the risks of overall, local, and systemic donation-related adverse reactions between the two age groups. Restricted cubic spline analysis was used to assess the continuous association between donor age and the risk of overall adverse reactions. Poisson GEE models were used to compare annual donation frequency, and donation participation and contributions to the blood supply among donors aged 56-65 years were evaluated. The study was approved by the Ethics Committee of the Institute of Blood Transfusion, Chinese Academy of Medical Sciences (No.2025012) and registered with the Chinese Clinical Trial Registry (ChiCTR2500114960). Results: A total of 1 960 711 donations were included in the 18-55-year group and 59 696 in the 56-65-year group. The overall donation-related adverse reaction rates were 3.890‰and 0.704‰, respectively. Multivariable GEE analysis showed that, compared with donors aged 18-55 years, those aged 56-65 years had lower risks of overall adverse reactions (adjusted OR=0.294, 95%CI: 0.217-0.398, P<0.001) and systemic adverse reactions (adjusted OR=0.163, 95%CI: 0.101-0.263, P<0.001), whereas no statistically significant difference was observed in the risk of local adverse reactions (adjusted OR=1.337, 95%CI: 0.487-3.670, P=0.573). Donor age was nonlinearly associated with the risk of overall adverse reactions (P overall<0.001, P nonlinear<0.001), with the risk generally decreasing with increasing age between 18 and 65 years. The mean annual donation frequency was higher among donors aged 56-65 years than among those aged 18-55 years (1.63 vs 1.24 donations per year; adjusted IRR=1.34, 95%CI: 1.30-1.39, P<0.001). During the study period, donors aged 56-65 years contributed 2.95% of all donations; their whole-blood donations and whole-blood collection volume accounted for 2.36% and 2.37% of the corresponding totals, respectively. Conclusion: Under current health screening and standardized donor management, donors aged 56-65 years did not show an increased risk of short-term donation-related adverse reactions and demonstrated a higher annual donation frequency, together with a measurable contribution to the blood supply. These findings support appropriately extending the upper age limit for voluntary blood donation under strict health screening to broaden the donor pool and supplement the blood supply.

OBJECTIVE To construct a multimodal similarity model for Chinese drug names and design optimized display names，compare the potential confusion risk of display names of the same drug catalogue in different scenarios，so as to provide a quantitative basis for the management of drug display names.METHODS A total of 1 221 drug entries were extracted from the drug dictionary of a tertiary grade A hospital，forming 744 810 drug pairs. “Five rules” were summarized based on the confusion characteristics of candidate confusable drug pairs under the currently used in-hospital display names （Scenario 1） and standard display names （Scenario 2），to generate optimized display names （Scenario 3）. A multimodal similarity model integrating Pinyin，glyph，character sequence and rendered visual features was constructed. The same threshold （total similarity S total ≥0.70） was adopted to screen candidate confusable drug pairs. Confusion risk grading and transition，confusion characteristic labeling，confusion network clustering and residual cluster analysis were carried out. The naming mechanism of optimized display names was investigated through display morphology indicators and rule ablation，and the robustness of the comparison results among the three scenarios was evaluated through similarity threshold and fusion weight sensitivity analysis.RESULTS The numbers of candidate confusable drug pairs in the three scenarios were 156，269 and 83 respectively，among which the number of pairs at high risk and above was 109， 215 and 64 respectively. Compared with Scenario 1，Scenario 3 reduced the number of candidate confusable drug pairs by 46.8%，and the number of those at high risk or above decreased by 41.3%. Display morphology analysis showed that Scenario 3 had the lowest average ink density （0.057 3） and the largest average number of structural slots （2.99）. Rule ablation analysis showed that after disabling the rule of manufacturer characteristic abbreviation prompts，the number of candidate confusable drug pairs increased the most （+74 pairs），while disabling structured naming alone resulted in a net decrease of 9 pairs. The residual clusters mainly involved drugs with the same active ingredient but different specifications or subtypes，as well as series products from the same manufacturer with similar main name stems. Under the threshold setting of 0.60 to 0.80 with a step size of 0.025 and 11 different weight configurations （including the baseline value），the number of candidate confusable drug pairs always maintained the ranking of Scenario 3＜Scenario 1＜Scenario 2.CONCLUSIONS The multimodal similarity model can be used for quantitative screening of potential confusion of Chinese drug display names，and the ranking of the number of candidate confusable drug pairs among scenarios remains stable within the set parameter range. The optimized display names based on the “five rules” can reduce the number of candidate confusable drug pairs， and the number of those at high risk or above in the hospital’s drug catalogue，but their impact on actual identification behavior and clinical medication safety still needs further verification.

ObjectiveTo construct and validate a clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure （CHF），aiming to assist clinical diagnosis and provide tools and methods for individualized treatment of CHF. MethodsThe clinical data of patients with chronic heart failure treated at Dongzhimen Hospital of Beijing University of Chinese Medicine from January 2022 to January 2024 were retrospectively collected. The patients were randomly divided into a training group and a validation group with a ratio of 7∶3. First， the least absolute shrinkage and selection operator （LASSO） regression analysis was used to preliminarily screen the predictive factors affecting the diagnosis of Qi deficiency and blood stasis syndrome in CHF. Subsequently， the Logistic regression method was applied to conduct a more in-depth and detailed analysis of these factors. Variables with P<0.05 in the results of the multi-factor Logistic regression were carefully selected and included. Based on the regression coefficients obtained from this analysis， a model was constructed， and a nomogram was accurately drawn. Using R software，the receiver operating characteristic （ROC） curve，calibration curve，and decision curve analysis （DCA） were precisely drawn. These analyses were used to comprehensively evaluate the model from three crucial aspects： discrimination，calibration，and clinical applicability. Additionally， the accuracy，specificity，sensitivity，positive predictive value，and negative predictive value of the model were meticulously calculated to conduct a more all-round and comprehensive assessment. ResultsIn total， 168 cases were successfully obtained in the training group， and 71 cases were included in the validation group. After a thorough comparison， it was found that there were no statistically significant differences in the baseline data between the two groups. After being rigorously screened by the LASSO-multivariate logistic regression method， dark red tongue，smoking history，cardiac troponin I，and N-terminal pro-B-type natriuretic peptide （NT-ProBNP） were identified as the influencing factors for diagnosing patients with the Qi deficiency and blood stasis syndrome in CHF. The constructed model demonstrated an area under the curve （AUC） of 0.812 in the training group and 0.719 in the validation group. The calibration curve showed that the predicted curve of the model was close to the actual observed curve. DCA indicated that the model could provide substantial clinical benefits for patients at the decision thresholds ranging from 0.2 to 0.9. ConclusionThe clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure constructed in this study shows good performance. It has certain application value in clinical practice， which may contribute to the improvement of the diagnosis and treatment of CHF patients with this syndrome.

Objective To evaluate the clinical efficacy of Long's spinal manipulation therapy combined with four postures of rotational tendon-releasing maneuver in treating lumbar disc herniation(LDH).Methods Sixty-eight patients diagnosed with LDH were enrolled from the Department of Acupuncture and Rehabilitation at Guangdong Second Traditional Chinese Medicine Hospital between July 2024 and December 2024.Patients were randomly divided into an observation group and a control group using a random number table,with 34 cases in each group.The control group received Long's spinal manipulation therapy,while the observation group received additional training in four postures of rotational tendon-releasing maneuver.Both groups were treated for 2 weeks,with a 1-month follow-up.Clinical efficacy was evaluated after treatment by comparing Visual Analogue Scale(VAS)scores,Oswestry Disability Index(ODI)scores,and Japanese Orthopaedic Association(JOA)scores before and after intervention.Spinal parameters including maximum lumbar curvature angle,pelvic tilt angle,and maximum vertebral rotation angle were assessed using the DIERS formetric 3D evaluation system.Results(1)The total effective rate was 94.12%(32/34)in the observation group and 91.18%(31/34)in the control group,and both groups achieved ideal therapeutic efficacy,but the difference was not statistically significant(P＞0.05).(2)After treatment,the VAS scores of patients in the two groups significantly improved(P＜0.05),and the observation group was significantly superior to the control group in improving VAS scores,with statistically significant differences(P＜0.05).At the 1-month follow-up after treatment,the VAS score of the observation group significantly improved(P＜0.05),and the observation group was significantly superior to the control group,and the difference was statistically significant(P＜0.05).(3)After treatment,the JOA and ODI scores of the patients in the two groups significantly improved(P＜0.05),and the observation group was significantly superior to the control group in improving the JOA and ODI scores,and the difference was statistically significant(P＜0.05).At 1-month follow-up after treatment,JOA and ODI scores of the observation group significantly improved(P＜0.05),and the observation group was significantly superior to the control group,with statistically significant differences(P＜0.05).(4)After treatment,the maximum angle of lumbar flexion,pelvic torsion angle,and maximum rotation angle of the vertebral body of the two groups of patients were significantly improved(P＜0.05),and the observation group was significantly better than the control group,and the difference was statistically significant(P＜0.05).At the 1-month follow-up after treatment,the maximum angle of lumbar flexion,pelvic torsion angle,and maximum vertebral rotation angle of the observation group were significantly improved(P＜0.05),and the observation group was significantly superior to the control group,and the difference was statistically significant(P＜0.05).Conclusion The combination of Long's spinal manipulation therapy and four postures of rotational tendon-releasing maneuve significantly improves spinal alignment,reduces pain and disability,and enhances quality of life in patients with LDH,demonstrating notable clinical efficacy.

Objective To investigate the relationship between the expression of platelet autophagy related factors and peritoneal metastasis of gastric cancer.Methods The data of 360 patients with gastric cancer who underwent surgery in Hunan Provincial People's Hospital from January 2021 to May 2023 were reviewed.Patients were divided into non-peritoneal metastasis group(n=322)and peritoneal metastasis group(n=38)according to whether peritoneal metastasis occurred or not.The following information was collected:patient's personal information(i.e.age,sex,body mass index)and tumor characteristics(i.e.location,size,pathological type,histopathological differentiation,lymphatic infiltration).Platelets were collected from all subjects,and the levels of autophagy-associated protein 7(ATG7),benzalkonium chloride 1(BECN1),microtubule-associated protein 1 light chain 3(LC3)and sequestosome 1(p62)were measured by enzyme-linked immunosorbent assay(ELISA).Results Among the 360 patients included,peritoneal metastasis was detected in 38 cases.Compared with the non-peritoneal metastasis group,the peritoneal metastasis group exhibited decreased BMI(P<0.05),while the tumor size,non-ulcerative tumor,number of lymph node metastasis,infiltration depth,number of cases of lymphatic invasion,platelet count,platelet LC3-Ⅱ level,platelet ATG7 level and CEA level were increased(P<0.05).Multivariate logistic regression analysis showed that BMI(OR=1.094),lymphatic invasion(OR=2.658),and LC3-Ⅱ(OR=3.793)and ATG7(OR=2.010)were independent influencing factors for peritoneal metastasis in patients with gastric cancer(P<0.05).LC3-Ⅱ>2.59ng/ml had the highest ability to predict peritoneal metastasis in patients with gastric cancer(AUC=0.932),followed by ATG7(AUC=0.916).Conclusions Elevated levels of platelet LC3-Ⅱ and ATG7 are independently related to peritoneal metastasis in patients with gastric cancer,and can be used to predict the occurrence of peritoneal metastasis,which is helpful to guide individualized treatment.
