ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription （BSTDP）. MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-LIT-Orbitrap-MS）. Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction （PPI） network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg （mpx： GFP）. At three days post-fertilization （3 dpf）， larvae of zebrafish were randomly assigned to blank group， model group， positive drug dexamethasone acetate group （75 μmol·L^-1）， and BSTDP groups with low， medium， and high doses （500， 1 000， and 2 000 mg·L^-1）. The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor kappa-B （NF-κB） signaling pathway and inflammatory factors including interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） were detected by Real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsA total of 120 chemical components were identified in BSTDP， among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis （RA） and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine， vomicine， sinapine， rehmannioside， cinnamyl alcohol glycoside， and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 （Akt1）， signal transducer and activator of transcription 3 （STAT3）， tumor necrosis factor （TNF）， TLR4， mitogen-activated protein kinase 14 （MAPK14）， and phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit α （PIK3CA）， thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L^-1. Compared to those in the blank group， zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region （P<0.01） and rising mRNA levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β （P<0.01）. Compared to that in the model group， the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses， as well as the dexamethasone acetate group （P<0.05， P<0.01）. There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β were significantly down-regulated （P<0.05， P<0.01）. ConclusionThis paper identifies the material basis of the efficacy of BSTDP， demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.

Purpose: This study aimed to evaluate the safety and efficacy of gemcitabine and cisplatin (GP) regimen in combination with immune checkpoint inhibitor sintilimab as neoadjuvant therapy for muscle-invasive bladder cancer (MIBC) patients and the feasibility of the following selective bladder sparing surgery. Materials and Methods: Patients with histopathologically confirmed urothelial carcinoma without distant metastases (T2-4a, N ≤ 1, M0, American Joint Committee of Cancer 8th) and with adequate organ function will be enrolled. The therapeutic regimen was sintilimab 200 mg once on day 8, gemcitabine 1,000 mg/m2 and cisplatin 35 mg/m2 once on days 1 and 8, every 21 days for four cycles. The primary endpoint was pathologic complete response (pCR, pT0N0) rate. The secondary end points were ypT < 2 rate, R0 resection rate, event-free survival, and safety. Results: From May 4, 2020, to May 20, 2023, 55 patients were enrolled. Forty-six patients were evaluated for efficacy. Among the 42 patients who underwent surgery, 16 patients (38.0%) achieved pCR. Thirty-three patients (78.6%) achieved pT < 2. With a median follow-up of 15.7 months, the 1-year event-free survival was 91.3%. Notwithstanding the poor pathological baseline characteristic of a high T3-T4a proportion (39.1%), a promising bladder preservation (including 22 patients transurethral resection of bladder tumor, 5 patients partial cystectomy, and 4 surveillances) rate was achieved (67.4%). The most common grade ≥ 3 treatment-related adverse events was neutropenia (n=15, 27.3%), which was related to chemotherapy. There were no grade 3 immune-related adverse events. Conclusion Neoadjuvant GP plus sintilimab is a promising regimen for MIBC patients, with relatively high pT < 2 rate and triggering the emerging roles for the multi-disciplinary team decision-making for bladder sparing surgery.

OBJECTIVE To formulate the Hazardous Drug List in China， and provide a scientific basis for standardizing the management of hazardous drugs， preventing and controlling occupational exposure risks in medical institutions at all levels in China. METHODS Under the joint organization of the Intravenous Medication Admixture Management Professional Committee of the Chinese Pharmaceutical Association and the National Medical Quality Control Center for Pharmaceutical Management， based on literature research and international hazardous drug lists and their development procedures， the scope of hazardous drug selection， selection principles， and evidence confirmation criteria were determined through expert panel seminars and expert questionnaire survey method （Delphi method）. Chemical drugs， biological agents， and Chinese patent medicines marketed in China that met the selecti on principles were screened to form the Chinese Expert Consensus on the Hazardous Drug List . RESULTS Five principles for selecting hazardous drugs were established （including protective labeling in package inserts， carcinogenicity， reproductive toxicity， genotoxicity， and organ toxicity at low doses）， along with the corresponding evidence confirmation criteria. The Hazardous Drug List containing 210 drugs was formulated， covering anti-tumor drugs， endocrine system drugs， nervous system drugs， immunomodulators， anti-infective drugs， cardiovascular system drugs， hematological system drugs， urinary system drugs， obstetrics and gynecology drugs， dermatological drugs and other categories. Compared with international hazardous drug lists， 25 newly included hazardous drugs were added， including 15 anti-tumor drugs， 6 Chinese patent medicines and 4 biological agents. In addition， 88 Chinese patent medicines that may have potential occupational exposure risks are listed in the appendix for reference by medical institutions in management. CONCLUSIONS The development of this consensus closely aligns with the actual clinical drug use in China， with a scientific and rigorous methodology， and can serve as a reference for medical institutions at all levels to standardize the management of hazardous drugs and prevent and control occupational exposure risks.

ObjectiveTo explore the value of deep learning reconstruction （DLR） in liver magnetic resonance imaging （MRI） by comparing the single-shot half-fourier rapid spin-echo sequence with DLR （HASTE_DLR） and diffusion-weighted imaging sequence with DLR （DWI_DLR） against the conventional BLADE and conventional DWI sequences. Methods70 patients underwent MRI examinations. Two observers independently evaluated the image quality of each sequence （including liver edge， blood vessels， lesion clarity， etc.）. Additionally， quantitative evaluation was conducted by measuring the signal to noise ratio （SNR） of liver parenchyma and lesions， contrast to noise ratio （CNR） of lesions， as well as apparent diffusion coefficient （ADC） values from conventional DWI and DWI_DLR. Intraclass correlation coefficient （ICC） was used to evaluate the consistency between the two observers. ResultsThe inter-observer consistency was high （ICC： 0.84-0.97）. The scanning time was reduced by 92.63% for HASTE_DLR and 50% for DWI_DLR sequences， respectively. The lesion clarity score of the HASTE_DLR group was significantly better than that of the BLADE group （P<0.001）， with artifacts reduced in both DLR sequences （P< 0.05）. The HASTE_DLR group demonstrated higher SNR and CNR， while the DWI_DLR group showed higher SNR and ADC values （all P<0.05）. ConclusionThe DLR technology can enhance the efficiency of liver MRI scans， improve image quality， and reduce artifacts， demonstrating promising application prospects.

Objective:To investigate the method and clinical efficacy of simultaneous correction of sunken upper eyelid during double eyelid plasty.Methods:A retrospective analysis was conducted on patients with single eyelids and sunken upper eyelid treated at the Department of Plastic Surgery, the First People’s Hospital of Zhengzhou, from October 2022 to February 2024. All patients underwent incisional double eyelid plasty with individualized correction based on depression severity. For mild depression, a combination of pretarsal orbicularis oculi muscle flap folding and orbital septum fat flap transposition was performed for correction. For moderate depression, additional autologous stromal vascular fraction (SVF)-gel grafting would be performed if residual depression persisted after the aforementioned approach. For severe depression, if the orbital fat was sufficient, the orbicularis oculi muscle flap folding, orbital fat flap repositioning and autologous SVF-gel transplantation were used. If there was insufficient orbital fat, the correction involved the use of a orbicularis oculi muscle flap and SVF-gel transplantation. Postoperative follow-up was conducted regularly, and related complications were statistically analyzed. Six months after the surgery, two blinded plastic surgeons evaluated outcomes via visual analog scale (VAS), including five aspects: symmetry of palpebral folds(including width and curvature of the double eyelid fold), fold contour, depression improvement, scar quality, overall eyelid aesthetics. Each aspect was rated on a scale from 1 to 10, with higher scores indicating better outcomes. Patient satisfaction was scored separately (1-5 per item), with higher scores indicating greater satisfaction.Results:A total of 64 patients were enrolled, including 4 males and 60 females; the age ranged from 19 to 66 years[ (32.0±9.7) years]. The degree of sunken upper eyelid was mild in 33 cases, moderate in 19 cases and severe in 12 cases. All patients underwent double eyelid plasty and orbicularis oculi flap folding. Based on this, 45 cases (33 mild and 12 moderate cases) underwent orbital septum fat flap transposition, 11 severe cases underwent SVF-gel grafting, and 8 cases (7 moderate and 1 severe cases) required combined approaches to correct depression. During the procedure, 19 cases (38 sides) received (1.8±0.8) ml of SVF-gel injection. Among these cases, one case with severe sunken upper eyelid who did not receive orbital fat transfer was injected with high density fat (left side: 0.6 ml, right side: 0.8 ml) due to insufficient SVF-gel volume. Two cases with severe sunken upper eyelid who only had autologous SVF-gel transplantation did not fully correct the depression within 3 months post-surgery received a second SVF-gel injection[(1.0±0.1) ml]. Follow-up was conducted for 6 to 12 months after surgery. All patients experienced varying degrees of eyelid edema, which typically lasted 2 to 3 months. Ecchymosis (34 sides), conjunctival congestion (3 sides), and temporary ptosis (5 sides) all resolved within 2 weeks. Pigmentation (14 sides) and scar hyperplasia (3 sides) disappeared or stabilized within 6 months. No patients developed complications such as incision infection, hematoma, fat liquefaction, local skin unevenness, or induration. The surgeons’ VAS scores of the above five indicators were all > 8 points, and the satisfaction scores of patients for the five indicators were all > 4 points. In both scoring, the improvement of sunken upper eyelid scored the highest, which were (9.2 ± 0.9) points and (4.8 ± 0.6) points respectively.Conclusion:For patients with single eyelids and varying degrees of sunken upper eyelid, performing double eyelid plasty and orbicularis oculi muscle flap folding, individualized correction is achieved through autologous fat redistribution techniques, based on the severity of the sunken upper eyelid and the amount of orbital fat. This single procedure can restore upper eyelid volume and rejuvenate the appearance, resulting in a natural and aesthetically pleasing double eyelid with minimal complications and high patient satisfaction.

A Salmonella bacteriophage,PJN025,was isolated from wastewater and characterized for its biological properties,including whole-genome sequencing and assessment of therapeutic poten-tial in animal infection models.Transmission electron microscopy classified it within the Caudovi-ricetes family.PJN025 selectively lysed S.typhimurium and S.enteritidis with an incubation period of approximately 10 min,a burst time of 80 min,and an average burst size of approximately 132 PFU/cell,demonstrating effective bactericidal activity.The phage showed robust stability at temperatures ranging from 30 to 70 ℃ and pH levels from 3 to 12.Whole-genome sequencing re-vealed a complete genome length of 46 478 bp with a G+C content of 45.9％,consisting of 82 open reading frames and one tRNA.No known virulence or resistance genes were found.In Galleria mellonella infection model,a survival rate of 70％was achieved with a preventative dose of 1 × 108 PFU/mL PJN025,compared to a 5％survival rate in the positive control group after 48 h of bacterial challenge.In SPF mice infected with S.typhimurium via intraperitoneal injection,all mices in the positive control group died within five days.However,in the co-infection group treated with 1×108 PFU/mL PJN025,a promising survival rate of 60％was observed.This study showed that the bacteriophage PJN025 had strong specificity,high lytic efficiency,good acid and alkali tol-erance,strong heat resistance,and good safety and prevention effects,providing materials and ex-perimental basis for the development of subsequent phage products.

Objective To observe the value of 68Ga-DOTA-NOC PET/CT for diagnosing pheochromocytoma(PCC)and paraganglioma(PGL).Methods Thirty-eight patients with suspected or confirmed PCC/PGL who underwent 68 Ga-DOTA-NOC PET/CT were retrospectively enrolled,among them 20 cases underwent 131I-metaiodobenzylguanidine(MIBG)SPECT/CT during the same period.The value of 68Ga-DOTA-NOC PET/CT for diagnosing PCC/PGL at individual and lesion levels were analyzed and compared to the results of 131I-MIBG SPECT/CT.Results Among 38 cases,there were 20 cases of PCC,14 cases of PGL,1 case of adrenocortical carcinoma and 3 cases of benign adrenal hyperplasia.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of 68 Ga-DOTA-NOC PET/CT for diagnosing PCC/PGL in all 38 cases was 87.88％(29/33),60.00％(3/5),93.55％(29/31),42.86％(3/7)and 84.21％(32/38),respectively.Totally 188 lesions were detected in 34 cases,with detection rate of 89.95％(188/209).For 20 patients who underwent both 2 kinds examinations,the detection rate of bone,lymph node,liver,lung metastases and the overall lesions of 68Ga-DOTA-NOC PET/CT were all higher than those of 131I-MIBG SPECT/CT(all P＜0.05).No significant difference of diagnostic accuracy of PCC/PGL was found between 68 Ga-DOTA-NOC PET/CT and 131I-MIBG SPECT/CT(P＞0.05).Conclusion The value of 68 Ga-DOTA-NOC PET/CT for diagnosing PCC/PGL was comparable to that of 131I-MIBG SPECT/CT,but the former showed higher detection rate of metastases,hence being helpful to staging and risk stratification of PCC/PGL.
