Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

This study aims to establish an antibody detection method for porcine deltacoronavirus (PDCoV). The recombinant proteins PDCoV-N1 and PDCoV-N2 were expressed via the prokaryotic plasmid pColdII harboring the N gene sequence of the PDCoV strain CH/XJYN/2016. The reactivity and specificity of PDCoV-N1 and PDCoV-N2 with anti-PEDV sera were analyzed after the recombinant proteins were analyzed by SDS-PAGE and purified by the Ni-NTA Superflow Cartridge. Meanwhile, Western blotting and indirect immunofluorescence assay were carried out separately to validate the recombinant proteins PDCoV-N1 and PDCoV-N2. Finally, we established an indirect ELISA method based on the recombinant protein PDCoV-N2 after optimizing the conditions and tested the sensitivity, specificity, and reproducibility of the method. Then, the established method was employed to examine 102 clinical serum samples. The recombinant protein PDCoV-N2 showed low cross-reactivity with anti-PEDV sera. The optimal conditions of the indirect ELISA method based on PDCoV-N2 were as follows: the antigen coating concentration of 1.25 μg/mL and coating at 37 ℃ for 1 h; blocking by BSA overnight at 4 ℃; serum sample dilution at 1:50 and incubation at 37 ℃ for 1 h; secondary antibody dilution at 1:80 000 and incubation at 37 ℃ for 1 h; color development with TMB chromogenic solution at 37 ℃ for 10 min. The S/P value ≥ 0.45, ≤0.38, and between 0.45 and 0.38 indicated that the test sample was positive, negative, and suspicious, respectively. The testing results of the antisera against porcine epidemic diarrhea virus (PEDV), porcine circovirus 2 (PCV2), transmissible gastroenteritis virus (TGEV), foot-and-mouth disease virus (FMDV), and African swine fever virus (ASFV) showed that the S/P values were all less than 0.38. The testing results of the 800-fold diluted anti-PDCoV sera were still positive. The results of the inter- and intra-batch tests showed that the coefficients of variation of this method were less than 10%. Clinical serum sample test results showed the coincidence rate between this method and neutralization test was 94.12%. In this study, an ELISA method for the detection of anti-PDCoV antibodies was successfully established based on the truncated N protein of PDCoV. This method is sensitive, specific, stable, and reproducible, serving as a new method for the clinical diagnosis of PDCoV.

Reasonable disciplinary planning is an important prerequisite for the high-quality development of multi-campus hospitals. In order to promote the rational layout and homogeneous management of multi-campus hospitals, a large public hospital explored multi-campus discipline planning from 2021 to 2022 based on preliminary research, following the principles of management integration, layout differentiation, resource optimization, maximum efficiency, and high-quality development, as well as according to the functional positioning of each hospital(headquarters, south, west, north, and infectious disease hospital), the needs of surrounding residents, and resource allocation. This practice had improved the development of advantageous specialties of sub-campus, promoted the innovation of technologies, and improved the overall medical service capacity of the hospital. The number of outpatients/emergency patients in the hospital had increased from 5.013 million in 2020 to 6.7 million in 2023, and the average length of stay had been shortened from 7.76 days to 6.17 days. It had initially achieved a disciplinary development strategy of " grouping, differentiation, and integration", which could provide reference and guidance for other public hospitals to promote the discipline development and construction for multi-campus hospitals.

Objective To investigate the prevalence and influencing factors of job burnout among medical staff in secondary and lower-level public hospitals in a suburban area of Shanghai City. Methods A total of 1 959 in-service medical staff from 15 grade Ⅱ and lower-level public hospitals were selected as the research subjects using cluster sampling method. The Maslach Burnout Inventory-Human Service Survey was used to investigate their job burnout situation. Results The median and the 25th and 75th percentiles of job burnout scores for the research subjects were 2.7 (2.1, 3.1) points, and the detection rate of job burnout was 56.6% (1 109/1 959). The detection rate of mild, moderate, and severe job burnout was 26.7%, 18.5%, and 11.4%, respectively. The results of multiple linear regression analysis showed that medical staff aged 20-<31、31-<41、41-<51 had a higher risk of job burnout than those the age of ≥51 (P<0.01), unmarried medical staff had a higher risk of job burnout than married medical staff (P<0.05), intermediate professional title medical staff had a higher risk of job burnout than senior professional title medical staff (P<0.05), medical staff in grade Ⅱ hospitals had a higher risk of job burnout than those in gradeⅠ hospitals (P<0.01), and medical and nursing staff had a higher risk of job burnout than pharmaceutical and technical staff (P<0.01), after excluding confounding factors such as gender, professional title, educational level, and management position. Conclusion Job burnout is prominent among medical staff in grade Ⅱ and lower-level public hospitals in suburban Shanghai City. Age, marital status, professional title, hospital level, and job type are the independent influencing factors of their job burnout.

OBJECTIVE To explore the application value of indocyanine green combined with near-infrared autofluorescence imaging technique in identifying pathological parathyroid glands during surgery for primary hyperparathyroidism (PHPT). METHODS Data from 40 patients with PHPT treated in Beijing Tongren Hospital,Capital Medical University were collected,including 10 patients in the indocyanine green treated group and 30 patients in the non-treated group. All patients underwent surgical treatment to remove the affected parathyroid glands. Near-infrared autofluorescence imaging was used for image acquisition,and ImageJ software was used for fluorescence intensity analysis. RESULTS The fluorescence intensity of the pathological parathyroid glands in the indocyanine green-treated group was significantly higher than that in the non-treated group(142.7±23.7 vs. 94.5±31.4,t=-4.434,P=0.000);the fluorescence ratio of pathological parathyroid glands/thyroid glands was significantly higher than that in the non-treated group(1.6±0.3 vs. 1.2±0.4,t=-3.162,P=0.004). There was no correlation between the fluorescence intensity of parathyroid glands in the non-treated group and preoperative blood calcium(r=0.029,P=0.088) and preoperative PTH level(r=-0.142,P=0.455),and there was also no correlation between the fluorescence intensity of parathyroid glands in the treated group and preoperative blood calcium(r=0.206,P=0.568) and preoperative PTH level(r=0.160,P=0.658). The detection rate of near-infrared light in the non-treated group was 53.3％(16/30),while that in the treated group was 100％(10/10). The average detection time for the non-treated group was (71.0±16.9)minutes,while that for the treated group was (52.7±11.1)minutes,with a significant difference between the two groups(t=3.187,P=0.003). CONCLUSION The combination of indocyanine green and near-infrared autofluorescence imaging technique is helpful for identifying the diseased parathyroid glands during the surgical treatment of PHPT.

The recognition of the innate immune system is the first line of defense for host protec-tion against invading microbes.Toll-like receptors(TLRs)are well-characterized pattern recogni-tion receptors that are critical for recognizing pathogen-associated molecular pattern(PAMP)and regulating the activation of antigen-presenting cells and key cytokines.Recognition of protozoon parasite genomic DNA by TLR9 activates transcription factors such as NF-κB,IRF3/7,and MAPK,which then induce the production of pro-inflammatory cytokines and type Ⅰ interferons.During parasite infection,MyD88 serves as a critical adapter protein for TLR9 to recognize PAMPs.Here,we review the TLR9-MyD88 pathways and their importance in the inflammatory re-sponse in some common protozoan parasite infections.We also discuss the impact of the subcellular localization of TLR9 in parasitic infectious diseases.By emphasizing current developments in these fields,the review aims to lay the foundation for future research on both the complexity of host-par-asite interactions and the prevention of protozoan parasitic diseases.
