OBJECTIVE: To investigate the predictive value of the prognostic nutritional index (PNI) and systemic inflammatory response index (SIRI) for short-term efficacy and prognosis in newly treated patients with peripheral T-cell lymphoma (PTCL). METHODS: The general data, laboratory indicators, disease stage and other clinical data of 91 newly treated PTCL patients admitted to the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2023 were retrospectively analyzed. The optimal cutoff values for PNI and SIRI were determined using receiver operating characteristic (ROC) curves, and the patients were stratified into groups based on these cutoffs to compare clinical features and short-term efficacy between the different groups. Kaplan-Meier method was used to plot survival curves, and univariate and multivariate analyses were performed to identify the factors affecting overall survival (OS). RESULTS: The optimal cutoff values for PNI and SIRI were 45.30 and 1.74×10⁹/L, respectively. Patients in different PNI groups showed statistically significant differences in age, Ann Arbor stage, lactate dehydrogenase (LDH) level, international prognostic index (IPI), prognostic index for PTCL-not otherwise specified (PIT), pathological subtypes, and complete response (CR) rate (P < 0.05). PTCL patients in different SIRI groups exhibited significant differences in Ann Arbor stage, LDH level, IPI score, PIT score, and CR rate (P < 0.05). Logistic regression analysis showed that age ≥60 years old (OR =2.750), Ann Arbor stage Ⅲ-Ⅳ (OR =5.200), IPI score ≥2 (OR =7.650), low PNI (OR =3.296), and high SIRI (OR =3.130) were independent risk factors affecting treatment efficacy in PTCL patients (P < 0.05). Cox proportional hazards regression model analysis showed that low PNI and elevated β₂-microglobulin (β₂-MG) levels were independent risk factors affecting OS (P < 0.05). CONCLUSION PNI and SIRI have certain application value in evaluating short-term efficacy and prognosis in patients with PTCL. Compared with SIRI, PNI demonstrates greater predictive value for patient prognosis.

OBJECTIVES: To explore the underlying pharmacological mechanisms and its potential effects of Chinese medicine herbal formula Sini Powder (SNP) on hepatocellular carcinoma (HCC). METHODS: The active components of SNP and their in vivo distribution were identified using ultraperformance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Construction of component-target-disease networks, protein-protein interaction network, Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and molecular docking were employed to analyze the active components and anti-HCC mechanisms of SNP. Cell viability assay and wound healing assay were utilized to confirm the effect of SNP-containing serum (2.5%, 5.0%, 10%, 20%, and 40%), isoprenaline or propranolol (both 10, 100, and 1,000 µ mol/L) on proliferation and migration of HepG 2 or Huh7 cells. Meanwhile, the effect of isoprenaline or propranolol on the β 2 adrenergic receptor (ADRB2) mRNA expression on HepG2 cells were measured by real-time quantitative reverse transcription (RT-qPCR). Mice with subcutaneous tumors were either subjected to chronic restraint stress (CRS) followed by SNP administration (364 mg/mL) or directly treated with SNP (364 mg/mL). These two parallel experiments were performed to validate the effects of SNP on stress responses. Stress-related proteins and hormones were quantified using RT-qPCR, enzyme-linked immunosorbent assay, and immunohistochemistry. Metagenomic sequencing was performed to confirm the influence of SNP on the gut microbiota in the tumor-bearing CRS mice. RESULTS: The distribution of the 12 active components of SNP was confirmed in various tissues and feces. Network pharmacology analysis confirmed the anti-HCC effects of the 5 active components. The potential anti-HCC mechanisms of SNP may involve the epidermal growth factor receptor (EGFR), proto-oncogene tyrosine-protein kinase Src (SRC) and signal transducer and activator of transcription 3 (STAT3) pathways. SNP-containing serum inhibited the proliferation of HepG2 and Huh7 cells at concentrations of 2.5% and 5.0%, respectively, after 24 h of treatment. Furthermore, SNP suppressed tumor progression in tumor-bearing mice exposed to CRS. SNP treatment also downregulated the expressions of stress-related proteins and pro-inflammatory cytokines, primarily by modulating the gut microbiota. Specifically, the abundance of Alistipes and Prevotella, which belong to the phylum Bacteroidetes, increased in the SNP-treated group, whereas Lachnospira, in the phylum Firmicutes, decreased. CONCLUSION SNP can combat HCC by alleviating stress responses through the regulation of gut microbiota.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Objective To establish a high performance liquid chromatography(HPLC)method for determining the free concentration of voriconazole in human plasma and to use it for clinical therapeutic drug monitoring(TDM).Methods Hollow fiber centrifugation ultrafiltration(HFCF-UF)pretreatment was used to obtain free voriconazole in plasma,and the content was determined by HPLC.Chromatographic column:Diamond C18 column(250.0 mm × 4.6 nm,5 μm),column temperature:30 ℃;mobile phase:water-acetonitrile=60∶40(v∶v)at a flow rate of 1.0 mL·min-1;wavelength:254 nm;injection volume:20 μL.The specificity,linear relationship,lower limit of quantification,precision,recovery rate,and stability of this method were investigated,and clinical plasma samples were determined.Results The linearity was good within the range of 0.10-10.00 μg·mL-1,and the standard curve equation was y=28 607x-35.93(r=0.999 1),and the lower limit of quantification was 0.10 μg·mL-1;the absolute recovery rate and relative recovery rate were 95.73％-97.76％and 96.64％-102.93％,respectively.The relative standard deriation of intra-day and inter-day precision were both less than 10％;the stability was good when plasma samples were repeatedly freeze-thawed three times or stored at-40 ℃ for 7 days,and at room temperature for 6 hours after sample processing.The free concentration of voriconazole in 37 plasma samples was 0.38-7.18 μg·mL-1,and plasma protein binding rates were(50.84±14.76)％,and there was a certain correlation between free concentration and total concentration.Conclusion The HFCF-UF combined with HPLC method for determining the free concentration of voriconazole in plasma is a simple,accurate,and applicable method for clinical TDM.

Objective To study the risk factors and prognostic characteristics of pediatric silent lupus nephritis(SLN)with class Ⅲ to V.Methods A retrospective study was conducted to collect clinical data from 30 children diagnosed with SLN at the Department of Pediatrics,Second Xiangya Hospital,Central South University,from May 2007 to April 2023.Based on renal pathological classification,the patients were divided into a class Ⅱ group(12 cases)and a class Ⅲ to Ⅴ group(18 cases).The risk factors for the occurrence of class Ⅲ to Ⅴ SLN were analyzed,and the prognostic characteristics were summarized.Results Among the 30 SLN patients,the median follow-up time was 61.50 months.There were no statistically significant differences in the proportions of patients who discontinued glucocorticoids or achieved low disease activity status,nor in the annual decline rate of estimated glomerular filtration rate(eGFR)between the class Ⅱ and class Ⅲ to V groups(P>0.05).However,three patients in the class Ⅱ group progressed to stage 1 chronic kidney disease(CKD),while eight patients in the class Ⅲ to Ⅴ group reached stage 1 CKD,and four patients reached stage 2 CKD.Among the 26 female SLN patients,serum complement C3 levels in the class Ⅲ to Ⅴ group were lower than those in the class Ⅱ group(P<0.05).Serum C3 levels in SLN patients,as well as in female SLN patients,were negatively correlated with the fluorescence intensity of IgA,IgG,and C3 immune complexes in the kidneys(P<0.05).Additionally,serum C3 levels in female SLN patients were negatively correlated with the renal pathological activity index(P<0.05).Binary logistic regression analysis indicated that being female and having low serum complement C3 levels were risk factors for the occurrence of class Ⅲ to Ⅴ SLN in children(P<0.05).Conclusions Class Ⅲ to Ⅴ SLN is not uncommon among SLN children,and there remains a risk of long-term renal function progression.Being female and having low serum complement C3 levels are identified as risk factors for class Ⅲ to Ⅴ SLN in children.

Objective To analyze the cerebral blood flow changes in patients with newly diagnosed untreated early-onset depression(EOD),using three-dimensional pseudo-continuous arterial spin labeling(3D-pCASL),and to explore its relationship with clinical phenotypes.Methods The Hamilton Depression Scale(HAMD),Childhood Trauma Questionnaire(CTQ)scores,3D T1WI,and 3D-pCASL brain images of 65 untreated EOD patients and 55 healthy volunteers(HC group)were collected.SPM 12 and DPABI_V7.0 software were used to preprocess and analyze the whole brain images in two groups.Xjview software was used to analyze the value of cerebral blood flow(CBF)at the whole brain level of the two groups,and SPSS 25.0 software was used to evaluate the correlation of CBF values with HAMD scores and CTQ scores.Results Compared with the HC group,the CBF of the EOD group was reduced significantly[P＜0.05,cluster size＞50,false discovery rate(FDR)correction]in the right opercular inferior frontal gyrus(t=5.89),right temporo-parieto-occipital(TPO)region(t=6.49),and blood perfusion increased significantly(P＜0.05,cluster size＞50,FDR correction)in the left superior frontal gyrus(t=5.31)and left insular lobe(t=4.70).Conclusion The proportion of EOD patients with childhood trauma experience is relatively large.EOD patients have both reduced areas and increased areas in cerebral perfusion.The CBF value of the right TPO area is negatively correlated with HAMD scores;The CBF value of the left superior frontal gyrus is positively correlated with the total score of CTQ and the index of physical neglect score in CTQ,which is different from the result of studies that do not distinguish between early-onset and late-onset depression.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

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.

OBJECTIVE: To investigate the inflammatory effects of Cinobufotalin on monocytes in resting state and macrophages in activated state and its molecular mechanism. METHODS: THP-1 cells were stimulated with Phorbol 12-myristate 13-acetate to induce differentiation into macrophages. Lipopolysaccharides was added to activate macrophages in order to establish macrophage activation model. Cinobufotalin was added to the inflammatory cell model for 24 h as a treatment. CCK-8 was used to detect cell proliferation, Annexin V /PI double staining flow cytometry was used to detect cell apoptosis, flow cytometry was used to detect macrophage activation, and cytometric bead array was used to detect cytokines. Transcriptome sequencing was used to explore the gene expression profile regulated by Cinobufotalin. Changes in the significantly regulated molecules were verified by real-time quantitative polymerase chain reaction and Western blot. RESULTS: 1∶25 concentration of Cinobufotalin significantly inhibited the proliferation of resting monocytes(P<0.01), and induced apoptosis(P<0.01), especially the activated macrophages(P<0.001, P<0.001). Cinobufotalin significantly inhibited the activation of macrophages, and significantly down-regulated the inflammatory cytokines(IL-6, TNF-α, IL-1β, IL-8) released by activated macrophages(P＜0.001). Its mechanism was achieved by inhibiting TLR4/MYD88/P-IκBa signaling pathway. CONCLUSION Cinobufotalin can inhibit the inflammatory factors produced by the over-activation of macrophages through TLR4/MYD88/P-IκBa pathway, which is expected to be applied to the treatment and research of diseases related to the over-release of inflammatory factors.
