False-positive HIV-1 nucleic acid testing results in patients with severe thalassemia after receiving cell and gene therapy / 中华检验医学杂志

A 11-year old female patient with severe thalassemia, receipt a lentivirus-based cell and gene therapy (CGT) therapy in Shenzhen Children′s Hosptial on July 27th, 2021. At the two follow-up visits after discharge, patient were continuously tested positive for HIV screening through HIV Ag/Ab Combo assay (chemiluminescence Immunoassay), and the viral load results of HIV-1 nucleic acid testing (NAT) were both>5 000 copies/ml. The patient can be diagnosed with HIV infection according to the National Guideline for Detection of HIV/AIDS(2020 Revised Edition). The thorough investigation findings and supplementary experiment results indicated that the false-positive HIV-1 NAT results was caused by cross-reactivity between the target sites detected by conventional HIV-1 NAT reagents and the lentiviral vectors fragments integrated into the genome of patient′s hematopoietic stem/progenitor cells. In conclusion, it is important for laboratories to select appropriate HIV-1 NAT testing platforms which won′t cause cross-reactivity for the testing of samples from patients who have been treated with HIV-derived vectors. It is also recommended to design and develop NAT testing platforms with multiple target regions labeled by different fluorescents for HIV NAT supplementation experiment to reduce the risk of false-positive diagnoses of HIV infection.

Influencing factors of survival of patients with airway stenosis requiring clinical interventions after lung transplantation / 器官移植

Objective To analyze the influencing factors of survival of patients with airway stenosis requiring clinical interventions after lung transplantation. Methods Clinical data of 66 patients with airway stenosis requiring clinical interventions after lung transplantation were retrospectively analyzed. Univariate and multivariate Cox’s regression models were adopted to analyze the influencing factors of survival of all patients with airway stenosis and those with early airway stenosis. Kaplan-Meier method was used to calculate the overall survival and delineate the survival curve. Results For 66 patients with airway stenosis, the median airway stenosis-free time was 72 (52,102) d, 27% (18/66) for central airway stenosis and 73% (48/66) for distal airway stenosis. Postoperative mechanical ventilation time [hazard ratio (HR) 1.037, 95% confidence interval (CI) 1.005-1.070, P=0.024] and type of surgery (HR 0.400, 95%CI 0.177-0.903, P=0.027) were correlated with the survival of patients with airway stenosis after lung transplantation. The longer the postoperative mechanical ventilation time, the higher the risk of mortality of the recipients. The overall survival of airway stenosis recipients undergoing bilateral lung transplantation was better than that of their counterparts after single lung transplantation. Subgroup analysis showed that grade 3 primary graft dysfunction (PGD) (HR 4.577, 95%CI 1.439-14.555, P=0.010) and immunosuppressive drugs (HR 0.079, 95%CI 0.022-0.287, P<0.001) were associated with the survival of patients with early airway stenosis after lung transplantation. The overall survival of patients with early airway stenosis after lung transplantation without grade 3 PGD was better compared with that of those with grade 3 PGD. The overall survival of patients with early airway stenosis after lung transplantation treated with tacrolimus was superior to that of their counterparts treated with cyclosporine. Conclusions Long postoperative mechanical ventilation time, single lung transplantation, grade 3 PGD and use of cyclosporine may affect the survival of patients with airway stenosis after lung transplantation.

Preservation and functional maintenance of lung allograft / 器官移植

As the final resolution for end-stage lung disease, lung transplantation can not only significantly prolong the survival, but also remarkably improve the quality of life of recipients. In recent decades, with the advancement of surgical techniques, immunosuppressants and post-transplantation management, the quantity of lung transplantation has been surged around the globe. However, the shortage of donor lung has severely restricted the development of lung transplantation. It is necessary to develop innovative approaches to expand the donor pool. The number of donors and effective preservation and functional maintenance of potential donor lungs play a key role in expanding the donor pool. The quality of donor lung is a critical precondition to ensure the long-term survival of lung transplant recipients. Preservation and functional maintenance of donor lung are of significance for guaranteeing the quality of lung allograft. In this article, research progresses on the management and maintenance of donor lung before procurement, the procurement of donor lung and the preservation and functional maintenance of lung allograft were reviewed, aiming to provide reference for the development of lung transplantation in clinical practice.

Distribution of pathological types and epidemiological characteristics based on kidney biopsy in Northwest China

The spectrum of biopsy-confirmed kidney disease varies with regions and periods. We describe the distribution of pathological types and epidemiological characteristics of kidney diseases in Northwest China due to regional differences in geographical environment, social economy, and dietary habits. Methods: Kidney biopsy cases from 2005 to 2020 in Xijing Hospital were retrospectively analyzed. Pathological characteristics of patients in different periods were analyzed using the t test or chi-square test. Joinpoint regression was used to analyze trends in pathological types and disease spectrum. Results: A total of 10,528 eligible patients were included. Primary glomerular disease (PGD) accounted for the majority of the cases and exhibited an obvious downward trend, whereas secondary glomerular disease (SGD) showed an obvious upward trend. Among PGD, immunoglobulin A nephropathy (IgAN) remained the most common pathological type, and the detection rate of membranous nephropathy (MN) was significantly increased. Among SGD, Henoch-Schönlein purpura nephritis (HSPN) was the most common pathological type and may present a significant characteristic of Northwest China. Diabetic nephropathy (DN) exhibited the most obvious upward trend in the whole process, whereas the fastest growth since 2012 was in hypertensive nephropathy. Conclusion: The proportion of SGD increased whereas PGD declined. IgAN remained the most common PGD, and HSPN was the most common SGD. MN and DN showed the most obvious upward trend among PGD and SGD, respectively. Changes in the spectrum of kidney disease, especially the constituent ratio of SGD, pose a great challenge to public health.

The role of infection in the development of autoimmune diseases / 中华检验医学杂志

Autoimmune diseases refer to clinical diseases caused by the body′s autoimmune tolerance state being broken or autoimmune cells being abnormally regulated, and the immune system produces autoantibodies, causing self-tissue damage or abnormal function. Most of the causes are unknown and easy to repeat, causing a huge burden on the quality of life of patients. Infectious pathogens have a potential role in initiating autoimmune processes and exacerbating disease progression, and conversely, some pathogens can suppress autoimmune responses. This paper summarizes the relationship between different types of infection and autoimmune diseases. Possible mechanisms of action include molecular mimicry of pathogen antigens, activation of bystander T or B cells, modification of autoantigens, and epitope diffusion.

Comprehensive and deep profiling of the plasma proteome with protein corona on zeolite NaY / 药物分析学报

Proteomic characterization of plasma is critical for the development of novel pharmacodynamic bio-markers.However,the vast dynamic range renders the profiling of proteomes extremely challenging.Here,we synthesized zeolite NaY and developed a simple and rapid method to achieve comprehensive and deep profiling of the plasma proteome using the plasma protein corona formed on zeolite NaY.Specifically,zeolite NaY and plasma were co-incubated to form plasma protein corona on zeolite NaY(NaY-PPC),followed by conventional protein identification using liquid chromatography-tandem mass spectrometry.NaY was able to significantly enhance the detection of low-abundance plasma proteins,minimizing the"masking"effect caused by high-abundance proteins.The relative abundance of middle-and low-abundance proteins increased substantially from 2.54％to 54.41％,and the top 20 high-abundance proteins decreased from 83.63％to 25.77％.Notably,our method can quantify approxi-mately 4000 plasma proteins with sensitivity up to pg/mL,compared to only about 600 proteins iden-tified from untreated plasma samples.A pilot study based on plasma samples from 30 lung adenocarcinoma patients and 15 healthy subjects demonstrated that our method could successfully distinguish between healthy and disease states.In summary,this work provides an advantageous tool for the exploration of plasma proteomics and its translational applications.

Experts consensus on the procedure of dental operative microscope in endodontics and operative dentistry / 国际口腔科学杂志·英文版

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Expert consensus on digital guided therapy for endodontic diseases / 国际口腔科学杂志·英文版

Digital guided therapy (DGT) has been advocated as a contemporary computer-aided technique for treating endodontic diseases in recent decades. The concept of DGT for endodontic diseases is categorized into static guided endodontics (SGE), necessitating a meticulously designed template, and dynamic guided endodontics (DGE), which utilizes an optical triangulation tracking system. Based on cone-beam computed tomography (CBCT) images superimposed with or without oral scan (OS) data, a virtual template is crafted through software and subsequently translated into a 3-dimensional (3D) printing for SGE, while the system guides the drilling path with a real-time navigation in DGE. DGT was reported to resolve a series of challenging endodontic cases, including teeth with pulp obliteration, teeth with anatomical abnormalities, teeth requiring retreatment, posterior teeth needing endodontic microsurgery, and tooth autotransplantation. Case reports and basic researches all demonstrate that DGT stand as a precise, time-saving, and minimally invasive approach in contrast to conventional freehand method. This expert consensus mainly introduces the case selection, general workflow, evaluation, and impact factor of DGT, which could provide an alternative working strategy in endodontic treatment.

Protective effect of hydroxysafflor yellow A on lung injury associated with severe acute pancreatitis in mice / 中华急诊医学杂志

Objective:To investigate the protective effect and mechanism of hydroxysafflor yellow A (HSYA) on severe acute pancreatitis (SAP) related lung injury.Methods:Fifty mice were randomly (random number) divided into five groups: the sham-operated group, SAP group and different doses (20, 40 and 80 mg/kg) of HSYA pretreatment group. Mice were pretreated with HSYA 24 h before SAP induction, pancreatic and lung tissues were isolated for histopathological examination at 72 h after modeling, and bronchoalveolar lavage fluid (BALF) was collected for biochemical analysis. Results:Compared with the sham-operated group, serum amylase activity, lung injury pathological score and BALF protein concentration in the SAP group were significantly increased [(2120.44 ± 354.50) U/L vs. (226.72 ± 20.84) U/L; (6.91 ± 0.28) vs. (0.53±0.18); (2563.25±348.22) μg/mL vs. (345.62±56.35) μg/mL, all P<0.05]. Inflammatory factors tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels and myeloperoxidase (MPO) activity were increased [(120.5±14.25) pg/mL vs. (31.5±4.82) pg/mL; (214.72±10.62) pg/mL vs. (39.26±5.66) pg/mL; (4.52±0.34) U/mg vs. (1.03±0.17) U/mg]. Compared with the SAP group, HSYA pretreatment significantly attenuated SAP-related pancreatic and lung tissue damage and the activities of the inflammatory factors TNF-α, IL-6 and MPO in BALF. In addition, HSYA promoted the expression of the antioxidant protein heme oxygenase-1 and blocked the activation of the NF-κB signaling pathway. Conclusions:HSYA exerts anti-inflammatory and antioxidant activities to inhibit SAP-related lung injury, which indicated that HSYA may be a potential therapeutic drug for SAP-induced lung injury.
