Most patients with pancreatic cancer are already in the locally advanced or metastatic stage at initial diagnosis. While systemic chemotherapy provides clinical benefits for those with mid-to-late-stage pancreatic cancer, its efficacy is often limited by patient tolerance. In response to the dual clinical demands of robust antitumor activity and high targeting specificity, antibody-drug conjugate (ADC) has emerged as a promising solution. By conjugating highly selective monoclonal antibodies with potent cytotoxic small-molecule drugs, ADC achieves precise tumor-targeting while minimizing damage to healthy tissues, which thereby improves treatment tolerance. However, due to the complex pathological features of pancreatic cancer, no ADC has yet been approved for clinical use for this disease. A comprehensive evaluation of factors including ADC-specific targets, payload selection, antibody-drug linkage strategies, drug delivery mechanisms, tissue distribution variability, and tumor heterogeneity will be crucial to advancing the clinical translation of ADC for pancreatic cancer treatment.

BACKGROUND:
The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China.
METHODS:
This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences.
RESULTS:
Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n = 278] vs . 43.7% [ n = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses.
CONCLUSION
This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To compare the efficacy of gasless robotic surgery via transaxillary approach and combined axillary-retroauricular approach for unilateral N1b PTC, and to explore the safety and effectiveness of gasless robotic surgery via transaxillary approach for unilateral N1b PTC. Methods:Unilateral N1b PTC patients who underwent surgery in the Department of Otolaryngology, Sun Yat Sen Memorial Hospital, Sun Yat sen University between July 2016 and December 2024 were included and analyzed. According to the inclusion and exclusion criteria and the differences of surgical approaches, the patients were divided into the transaxillary approach(TA) group and the combined axillary-retroauricular approach(TARA) group. The demographic data, operation time, intraoperative blood loss, postoperative drainage volume, postoperative complications, shoulder function evaluation, postoperative visual analogue scale(VAS) of neck aesthetics and recurrence of the two groups were statistically analyzed. Results:A total of 88 patients undergoing gasless robotic surgery were included in this study, including 23 cases in the TA group and 65 cases in the TARA group. The proportion of males in the TA group was significantly higher than that in the TARA group(56.5% vs 21.5%, χ²=9.776, P=0.002). The total operation time in the TA group was significantly lower than that in the TARA Group(180.00[155.00, 220.00]min vs 220.00[177.50, 272.50]min, z=-2.775, P=0.006), and the postoperative blood loss in the TA group was significantly lower than that in the TARA Group(30.00[20.00, 50.00]ml vs 50.00[30.00, 60.00]ml, Z=-2.127, P=0.033). The proportion of area Ⅱ-Ⅴ in the TA group and the TARA group was 87.0% and 70.8%, respectively, and there was no significant difference between the two groups(P>0.05). There was no significant difference in lateral cervical lymph node dissection and central lymph node dissection between the two groups(P>0.05). During the follow-up period, no recurrence was found in the two groups, and there was no significant difference in the incidence of complications between the two groups(P>0.05). According to the stratification of dynamic recurrence risk assessment, it can be seen that the proportion of curative effect satisfaction in the TA group was as high as 95.7%, and that in the TARA group was as high as 81.5%, with no significant difference between the two groups. There was no significant difference in VAS score of neck, Constant Shoulder Score and NDⅡ scale between the two groups(P>0.05). Conclusion:Gasless robotic surgery via transaxillary approach for unilateral N1b PTC is safe and feasible, and the amount postoperative lymph node acquisition is equivalent to that of combined axillary-retroauricular approach, which can provide a new choice for the treatment of unilateral N1b PTC patients.

Objective:To evaluate the safety, feasibility, and technical advantages of the domestic Jingfeng single-port robotic surgical system in transoral and transaxillary approach surgeries for multisite diseases. Methods:A retrospective analysis was conducted on the clinical data of 6 patients who underwent Jingfeng SP1000 single-port robotic-assisted surgery at our hospital from June 2025 to July 2025. They were divided into the transoral robotic surgery group(4cases) and the transaxillary approach thyroid cancer radical resection group(2cases) based on surgical approaches. The transoral robotic surgery group included extended resection of right tonsillar cancer with cervical lymph node dissection, epiglottic cyst resection, extended resection of right pyriform sinus cancer with cervical lymph node dissection, and surgery for epiglottic cyst and obstructive sleep apnea(OSA). For each case, parameters including operative time, intraoperative blood loss, perioperative complications, robotic operation performance, and postoperative recovery were recorded. Results:All 6 surgeries were successfully completed without conversion to open surgery or system failure. In the transoral robotic surgery group, the mean robotic operation time was(60.00±34.88) minutes, and the mean intraoperative blood loss was 20.00(5.75,20.00)mL. In the transaxillary robotic surgery group, the robotic operation time was respectively 60.00 and 40.00 minutes, and the intraoperative blood loss was 10.00 and 5.00 mL, respectively. One case of minor perioperative complication(in the flap dissection area) occurred, with no severe complications reported. All patients recovered smoothly after surgery, with a median follow-up of 1.9 months showing no residual lesions, recurrence, or functional impairment. Conclusion:This case series confirms the safety and feasibility of the domestic Jingfeng single-port robot in transoral and axillary approach surgeries in oropharyngeal-head and neck surgery. Its single-port design reduces trauma and the risk of robotic arm collision, adapts to minimally invasive needs, and its domestic production attribute lowers costs to facilitate popularization, providing a new option for such patients.

Retrograde adeno-associated viruses (AAVs) are capable of infecting the axons of projection neurons and serve as a powerful tool for the anatomical and functional characterization of neural networks. However, few retrograde AAV capsids have been shown to offer access to cortical projection neurons across different species and enable the manipulation of neural function in non-human primates (NHPs). Here, we report the development of a novel retrograde AAV capsid, AAV-DJ8R, which efficiently labeled cortical projection neurons after local administration into the striatum of mice and macaques. In addition, intrastriatally injected AAV-DJ8R mediated opsin expression in the mouse motor cortex and induced robust behavioral alterations. Moreover, AAV-DJ8R markedly increased motor cortical neuron firing upon optogenetic light stimulation after viral delivery into the macaque putamen. These data demonstrate the usefulness of AAV-DJ8R as an efficient retrograde tracer for cortical projection neurons in rodents and NHPs and indicate its suitability for use in conducting functional interrogations.

ObjectiveTo elucidate the principles and methods of the Bayesian probabilistic linkage model, and to demonstrate the effect of applying the model in linking birth and death data. MethodsThrough the Shanghai birth and death registration system, data of 199 025 infants born in 2017 and 1 512 infants who died in 2017 and 2018 were collected. After cleaning the data, the data were divided into monthly blocks and fully linked. The Jaro-Winkler algorithm and Euclidean distance were employed to measure the similarity of fields for matching. A Bayesian probabilistic linkage model was constructed and the linking effect was evaluated using a confusion matrix. ResultsUsing the Bayesian probabilistic linkage model, the birth and death data of infants were effectively linked, revealing that 36.71% of infants who died in Shanghai were born outside the city, and the probability of infant death was 2.6‰. The confusion matrix of the test set showed a recall rate of 0.86, precision of 0.76, and an F-score of 0.81. ConclusionThe practical application of Bayesian probabilistic linkage demonstrates a good model performance, enabling the establishment of birth-death cohorts that more accurately reflect the true levels of infant mortality. Utilizing this technique to integrate data from different departments can effectively improve research efficiency in the field of public health.

BACKGROUND:Seed cells are seeded on three-dimensional scaffold materials,and three-dimensional culture in bioreactors is a common in vitro tissue engineering culture method,but the changes in cell proliferation and metabolic patterns in bioengineered blood vessel construction are still unclear. OBJECTIVE:To explore the metabolic changes of cells such as oxygen consumption and their causes during the whole process of biological vascular tissue construction by in vitro bioreactor. METHODS:The self-built vascular bioreactor system was used as the platform;bovine vascular smooth muscle cells were used as the seed cells,and a conventional CO2 incubator provided the external gas environment for the cultivation process.Seed cells were seeded on a tubular porous polyglycolic acid scaffold material for three-dimensional culture,and the whole process included a one-week resting period and a seven-week pulsating tensile stress stimulation loading period.A non-invasive monitoring system was built,and the optical dissolved oxygen patch method was used to monitor the changes of dissolved oxygen in the culture solution in the reactor,and the glucose consumption and lactic acid production were measured by regular sampling.CCK-8 assay was used to determine the proliferation of smooth muscle cells on polyglycolic acid three-dimensional scaffold materials.Nicotinamide adenine dinucleotide oxidation state and reduction state ratio(NAD+/NADH)was utilized to understand cell proliferation and metabolism in the early stage of culture.RT-qPCR and western blot assay were applied to detect the expression of proliferation-related genes(Ki67)and glycolysis-related genes(GLUT-1,LDHA). RESULTS AND CONCLUSION:(1)The dissolved oxygen level in the culture solution was(4.314±0.380)mg/L from the cell injection to the end of the resting period(the first week),and gradually stabilized at(1.960±0.866)mg/L after the tensile stress stimulation(the last seven weeks);the two had significant changes(P<0.05).(2)The ratio of glucose consumption to lactic acid production in the cell culture medium YL/G increased rapidly after the cells were injected,and the highest value was above 1 on the fifth day,and then slow down to 0.5(The mean value of YL/G in the resting period was 0.89 and the mean value in the pressurized period was 0.57,P<0.05).(3)CCK-8 assay results showed that A450 value gradually increased after the cells were injected,and reached the highest value on the fifth day,reaching 3.17,and then slowly decreased.At the same time,it was found that Ki67 mRNA was up-regulated on the third day of culture,and then declined.The expression level of Ki67 protein was higher from the third day to the fifth day.(4)The detection of NAD+/NADH showed that the increase was obvious from the fifth to the seventh day after the injection of cells,and the expression of glycolysis-related genes(GLUT-1 and LDHA)was up-regulated and changed synchronously,and the relative expression was higher in the first five days.(5)The results showed that the tissue-engineered blood vessels were constructed using the vascular bioreactor and the smooth muscle cells in the early stage mainly proliferated and exhibited a metabolic feature of low oxygen consumption.The metabolic characteristics of high oxygen consumption were observed during the pulsatile tensile stress stimulation stage.
