Despite publishing and securing research grants being obligatory in research universities, the literature on the
factors influencing academic productivity is relatively scarce. Thus, in this study, we aimed to determine the
personal and behavioural-related factors that influence the culture of publishing and securing research grants
among academicians with lower research-related performance. This cross-sectional study was conducted among 49
academic staff members of Universiti Kebangsaan Malaysia (UKM). A self-administered questionnaire consisting
of personal, attitude and behavioural (barriers, perceived stress scale, work extrinsic and intrinsic motivation
scale, psychological well-being scale, and basic needs satisfaction scale) questions were distributed during a
workshop and online. Simple linear regression (SLR) analyses were performed for each variable, followed by
multiple linear regression (MLR) to identify the associated factors of research output. After adjusting for covariates,
having a doctoral degree (β=0.396, 95% CI=0.221-2.146, p<0.05) and integrated regulation (β=0.574, 95%
CI=0.036-3.612, p<0.05) were found to be associated with research grant acquisition (R2=0.273). Moreover,
increasing age (β=0.426, 95% CI=0.088-0.397, p<0.05), living alone (β=0.331, 95% CI=0.944-6.626, p<0.05),
having a doctoral degree (β=0.248, 95% CI=0.174-6.747, p<0.05), environmental mastery (β=0.318, 95%
CI=0.013-0.347, p<0.05), self-acceptance (β=0.284, 95% CI=0.010-0.242, p<0.05), satisfaction incompetence
(β=0.273, 95% CI=0.001-0.200, p<0.05) and relatedness (β=0.280, 95% CI=0.001-0.116, p<0.05) were found to
be the factors that influence the publications produced among participants (R2
=0.423). The findings of this study
could be used by management to formulate effective strategies to increase the productivity of academics in their
research-related performance.

Chinese Journal of Biologicals 2026;39(03):264-269+276
ObjectiveTo construct a recombinant virus expressing tick-borne encephalitis virus(TBEV) prM-E protein using vesicular stomatitis virus(VSV) as a vector, and to identify it, so as to provide a basis for the research of TBEV vaccines based on VSV vector.MethodsThe prM-E gene of the TBEV Senzhang strain was inserted between the G and L genes of the VSV vector. The recombinant virus was rescued by co-transfecting BHK-21 cells infected by poxvirus containing T7 RNA polymerase with helper plasmids expressing VSV N, P, L, and G proteins. The supernatant was collected, and the recombinant virus rVSV-TBEVprM-E stably expressing prM-E was obtained after multiple passages. Western blot, immunofluorescence assay(IFA) and RT-PCR were used to identify the expression of prM-E protein and gene of rVSV-TBEVprM-E in cells. The viral titers of rVSV-TBEVprM-E at different time points were determined by plaque assay and the growth curve was plotted.ResultsTBEV prM-E gene was successfully inserted into the genome of recombinant virus rVSV-TBEVprM-E, and the expression of prM-E protein in BHK-21 cells was detectable. After serial passages, rVSV-TBEVprM-E achieved a viral titer of 6. 75 × 10~5 PFU/mL.ConclusionA recombinant virus rVSV-TBEVprM-E expressing prM-E protein was successfully constructed, which lays a solid experimental foundation for the related research of TBEV.

Chinese Journal of Biologicals 2026;39(03):277-281+288
ObjectiveTo analyze the glycan receptor binding characteristics of capsid proteins of GⅡ.5 norovirus(NoV) in order to lay a foundation for the development of antiviral drugs and vaccines for NoV.MethodsThe P proteins of GⅡ.5 N490 and GⅡ.5 12X were expressed in prokaryotic system respectively, purified using glutathione affinity chromatography, and then the binding characteristics of P proteins with saliva and glycan were detected by ELISA. The structure of two GⅡ.5 strains was modeled and the binding amino acids between the P protein and glycan were analyzed based on the epidemic GⅡ.17 KW308.ResultsThe relative molecular mass of the both P proteins of GⅡ.5 N490 and GⅡ.5 12X was 61 000,which were expressed in soluble from in the supernatant, and the purified concentration was 0. 2 mg/mL. The P proteins of two GⅡ.5 strains could bind to most of A, B, O secretory and non-secretory saliva. The P protein of GⅡ.5 N490 exhibited binding to H disaccharide, while the P protein of GⅡ.5 12X showed specific binding to H disaccharide and B trisaccharide. In addition, the model of two GⅡ.5 strains displayed a conformation similar to that of GⅡ.17 KW308. Among the six amino acid sites interacting with glycan, Arg349, Asp378, Gly443 of GⅡ.5 N490 and GⅡ.5 12X were the same as those of G Ⅱ.17 KW308, while Asn375, Glu380 and Phe444 were different from those of G Ⅱ.17 KW308.ConclusionThe two strains of G Ⅱ. 5 exhibit similar binding characteristics in saliva binding patterns with P proteins and both have a wide susceptible population, while the glycan binding patterns are slightly different.

The 2025 American Society of Clinical Oncology (ASCO) Annual Meeting was held in Chicago. At the meeting, researches on the treatment of epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) once again took the spotlight. Combination therapy strategies have demonstrated the potential to overcome resistance to EGFR tyrosine kinase inhibitor (EGFR-TKI) and prolong survival. Meanwhile, progress has also been made in individualized treatment strategies for young patients and those with fibrotic interstitial lung disease. However, the complexity of resistance mechanisms, special treatment considerations for different populations, and the impact of socioeconomic factors on treatment accessibility remain challenges in the field of EGFR-mutant NSCLC treatment. In the future, it is necessary to further explore more effective treatment regimens and expand the accessibility of precision medicine to maximize patient benefits.

Infective endocarditis (IE) is a life-threatening infectious disease. Although histopathological examination remains the gold standard for definitive diagnosis, it is performed in only a minority of patients; thus, the diagnosis of IE continues to rely predominantly on clinical manifestations. However, IE presents with highly variable systemic symptoms that often lack cardiac-specific features, posing significant diagnostic challenges. To address this complexity, multiple diagnostic criteria have been developed, integrating clinical presentation, imaging findings, and microbiological evidence. Over the past three decades, substantial shifts in the microbiological and epidemiological profiles of IE, coupled with advances in imaging modalities and laboratory diagnostics, have profoundly influenced diagnostic approaches, driving continuous refinement of diagnostic criteria. This review provides a comprehensive overview of the major diagnostic criteria for IE, traces their historical evolution, evaluates recent updates and diagnostic performance, and offers theoretical insights and practical implications to guide future research.

Objective To investigate the impact of intraoperative red blood cell (RBC) transfusion volume on the postoperative oxygenation index in lung transplant recipients. Methods This retrospective study analyzed the clinical data of patients who underwent lung transplantation at Wuxi People's Hospital Affiliated to Nanjing Medical University from 2021 to 2023. Patients were divided into a non-severe primary graft dysfunction (PGD) group and a severe PGD group based on whether their postoperative oxygenation index was>200 mm Hg at 0, 24, and 48 h. General patient data and intraoperative RBC transfusion volumes were compared between the two groups. A binary logistic regression model was constructed to explore the effect size (OR and its 95%CI) of RBC transfusion volume on postoperative oxygenation status at different time points (0, 24, and 48 h). The area under the receiver operating characteristic curve was calculated to evaluate the model's diagnostic performance. Results A total of 351 patients were included (260 males, 91 females), with ages ranging from 20 to 77 years. The OR for the effect of intraoperative RBC transfusion on poor oxygenation was 1.486 (95%CI 0.982 to 2.248, P=0.061) at 0 h postoperatively, 3.111 (95%CI 1.793 to 5.399, P<0.001) at 24 h, and 1.583 (95%CI 1.026 to 2.442, P=0.038) at 48 h. This indicated that as time progressed, the postoperative oxygenation status of lung transplant recipients was affected by the intraoperative transfusion volume. Furthermore, an RBC transfusion volume>975 mLhad a significant impact on patient oxygenation at 24 and 48 h postoperatively. Conclusion The volume of intraoperative RBC transfusion has a significant impact on the oxygenation status at 24 and 48 h postoperatively. Intraoperative RBC transfusion volume is associated with the occurrence of severe PGD after lung transplantation. Controlling the volume of RBC transfusion during lung transplantation may help reduce the incidence of severe PGD.
7.Interpretive radiology reports for lung cancer generated by GPT-4 large language model to enhance doctor–patient communication efficiency
Chinese Journal of Clinical Thoracic and Cardiovascular Surgery 2026;33(02):231-240
Objective To explore the application of the GPT-4 large language model in simplifying lung cancer radiology reports to enhance patient comprehension and doctor–patient communication efficiency. Methods A total of 362 radiology reports of non-small cell lung cancer (NSCLC) patients were collected from two hospitals between September and December 2024. Interpretive radiology reports (IRRs) were generated using GPT-4. Original reports (ORRs) and IRRs were compared through radiologist consistency evaluation and volunteer-based assessments of reading time, comprehension scores, and simulated communication duration. Results The average word count of ORRs was (459.83±55.76) words, compared with (625.42±41.59) words for IRRs (P<0.001). No significant differences were observed in expert consistency scores between ORRs and IRRs across dimensions of image interpretation accuracy, report detail completeness, explanatory depth and insight, and clinical practicality. Compared with reading ORRs, volunteers (simulated patient) read IRRs with shorter time [(346.88±29.15) s versus (409.01 ±102.40) s], with higher comprehension scores [(7.83±1.04) points versus (5.53±0.94) points] and shorter doctor-patient communication times [(317.31±57.81) s versus (714.20±56.67) s]. All differences were statistically significant (all P<0.001). Conclusion GPT-4 generated IRRs significantly improve patient comprehension and shorten communication time while maintaining medical accuracy. These findings suggest a new approach to optimizing radiology report management and enhancing healthcare service quality.

Objective To evaluate the impact of an integrated management mode of prenatal diagnosis-postnatal treatment for congenital heart disease (CHD) on perioperative and long-term outcomes of the arterial switch operation (ASO), and to analyze the efficacy of ASO in a single center. Methods This retrospective study analyzed the clinical data of 183 children who underwent ASO at Guangdong Provincial People’s Hospital from 2018 to 2024. The cohort included 106 (57.9%) patients of transposition of the great arteries with intact ventricular septum (TGA/IVS), 61 (33.3%) patients of transposition of the great arteries with ventricular septal defect (TGA/VSD), and 16 (8.7%) patients of Taussig-bing anomaly (TBA). Perioperative indicators were compared between 91 patients in the prenatal-postnatal integrated management group (an integrated group) and 92 patients in the traditional management group (a non-integrated group). Long-term survival and reoperation rates were analyzed using Kaplan-Meier curves. Results The overall perioperative mortality rate was 4.9% (9/183), showing a downward trend year by year. The primary cause of perioperative mortality was low cardiac output syndrome (LCOS), which occurred in 12 patients (6.6% incidence) with a mortality rate of 75.0%. The integrated group had a higher proportion of males (89.0% vs. 72.8%, P<0.05) and lower body weight [3.1 (2.7, 3.3) kg vs. 3.3 (3.0, 3.7) kg, P<0.05] compared to the non-integrated group. The age at surgery was significantly earlier in the integrated group [7 (3, 10) d vs. 14 (9, 48) d, P<0.05], and all children in the integrated group underwent ASO within the optimal surgical window (100.0% vs. 82.6%, P<0.05). Intraoperatively, cardiopulmonary bypass time [173 (150, 207) min vs. 186 (159, 237) min, P<0.05] and aortic cross-clamp time [100 (90, 117) min vs. 116 (97, 142) min, P<0.05] were significantly shorter in the integrated group. Although the integrated group had longer postoperative mechanical ventilation time [145 (98, 214) h vs. 116 (77, 147) h, P<0.05] and higher 48-hour maximum vasoactive inotropic score [15 (10, 21) points vs. 12 (8, 16) points, P<0.05], there was no statistically significant difference in the incidence of severe complications (LCOS, necrotizing enterocolitis, extracorporeal membrane oxygenation) or mortality rate (3.3% vs. 6.5%, P=0.51) between the two groups, despite earlier surgical intervention and a higher proportion of critically ill cases in the integrated group. The length of hospital stay in the emergency surgery group was significantly shorter than that in the elective surgery group [20 (15, 28) d vs. 25 (21, 30) d, P<0.05], suggesting that early surgery may be of potential benefit. A total of 163 patients were successfully followed up for a median of 4.7 years, with a 5-year survival rate of 95.1% and a freedom from reintervention survival rate of 95.1%. There were no late deaths, and the most common postoperative complication was pulmonary artery stenosis. Conclusion The integrated management model allowed critically ill children with lower body weights to safely undergo surgery, significantly optimizing the timing of surgery and shortening intraoperative times. The long-term risk of reoperation after ASO is primarily concentrated on pulmonary artery stenosis, necessitating long-term follow-up and monitoring.
