Objective:To investigate the feasibility of the bortezomib, lenalidomide, and dexamethasone (VRD) regimen combined with autologous hematopoietic stem cell transplantation (auto-HSCT) in patients with multiple myeloma (MM) and renal impairment, analyze treatment efficacy and renal responses stratified based on renal dysfunction severity, and explore the prognostic significance of early renal response and its affecting factors.Methods:This retrospective study, conducted at the First Affiliated Hospital of Soochow University, categorized 316 patients with newly diagnosed MM (NDMM) from August 2018 to October 2022 based on renal function for analysis of clinical characteristics, treatment response, and prognosis. Continuous variables were compared using t-tests or Mann-Whitney U tests, categorical variables utilizing Chi-square tests, survival outcomes employing Kaplan-Meier and Log-rank tests, and renal response predictors with logistic regression.Results:Patients were stratified based on baseline estimated glomerular filtration rate (eGFR) : normal [≥90 ml·min -1· (1.73 m 2) -1, n=160], mild [≥60 ml·min -1· (1.73 m 2) -1 to <90 ml·min -1· (1.73 m 2) -1, n=55], moderate [≥30 ml·min -1· (1.73 m 2) -1 to <60 ml·min -1· (1.73 m 2) -1, n=39], and severe impairment [<30 ml·min -1· (1.73 m 2) -1, n=62]. Moderate and severe renal impairment correlated with advanced International Staging System/Revised International Staging System classification, lower hemoglobin levels, frailty, and higher light-chain/IgD subtype prevalence ( P<0.05). Despite younger age ( P=0.001) and higher transplant rates ( P=0.041) in severe cases, overall response rates ( ORR: 93.7% ; ≥VGPR: 82.9% ) were comparable across groups ( P>0.05). Among 24 dialysis-dependent patients at diagnosis, 11 (45.8% ) achieved dialysis independence after induction [median: 3.0 (0.5–4.0) months], including 10 undergoing auto-HSCT. In 89 evaluable patients [baseline eGFR <50 ml·min -1· (1.73 m 2) -1], renal ORR (RORR) was 70.8% [rapid complete response: 31.5% ; rapid partial response: 11.2% ; rapid minimal response (RMR) : 28.1% ]. Renal response predicted better survival (overall survival: HR=0.36, 95% CI: 0.13–0.99, P=0.049). Moderate-to-severe renal impairment was associated with increased transplant-related adverse events and delayed engraftment ( P<0.05) ; however, auto-HSCT significantly improved outcomes after 33.5-month median follow-up (range: 2–65 months). Multivariate analysis identified 1q21+ ( OR=3.58, 95% CI: 1.17–11.02, P=0.026) and light-chain subtype ( OR=2.86, 95% CI: 1.08–7.69, P=0.036) as independent predictors of poor renal response. Conclusion:VRD regimen plus auto-HSCT demonstrates robust efficacy in NDMM, including patients with renal impairment, with a 70.8% RORR and manageable toxicity. Achieving ≥RMR correlates with superior prognosis, whereas 1q21+ and light-chain subtype independently predict inferior renal response.

Objective To study the relationship of serum 25-hydroxyvitamin D3[25-(OH)D3],myostatin(MSTN),limb skeletal muscle index(ASMI)with osteopenia(OP)in patients with rheumatoid arthritis(RA)complicated with sarcopenia(SA).Methods A total of 244 RA patients selected as case group,and 123 healthy people who underwent physical examination in our hospital during the same period were selected as control group.The general data,serum levels of 25-(OH)D3,MSTN,ASMI and peripheral blood immune cells were compared among the two groups.The diagnostic value of serum 25-(OH)D3,MSTN and ASMI in RA patients with SA complicated with OP and the correlation between serum 25-(OH)D3,MSTN,ASMI and peripheral blood immune cells were analyzed.Results The levels of serum 25-(OH)D3,peripheral blood regulatory T lymphocyte(Treg)cells and ASMI in the case group were lower than those in the control group,while the levels of serum MSTN,peripheral blood helper T lymphocyte 17(Th17)cells and Th17/Treg were higher than those in the control group(P＜0.05).Among the 244 RA patients,171 had no SA,73 had SA,and the incidence of SA was 29.92％.The levels of serum 25-(OH)D3,peripheral blood Treg cells and ASMI in the SA group were lower than those in the non-SA group,and the levels of serum MSTN,peripheral blood Th17 cells and Th17/Treg were higher than those in the non-SA group(P＜0.05).The levels of serum 25-(OH)D3,peripheral blood Treg cells and ASMI in the OP group were lower than those in the non-OP group,while the levels of serum MSTN,peripheral blood Th17 cells and Th17/Treg were higher than those in the non-OP group(P＜0.05).The area under the curve(AUC)of combined detection of serum 25-(OH)D3,MSTN and ASMI for the diagnosis of OP in RA patients with SA was higher than that of the three alone(P＜0.05).Serum 25-(OH)D3 and ASMI in RA patients with SA complicated with or without OP were negatively correlated with peripheral blood Th17 cell level and Th17/Treg(P＜0.05),and positively correlated with peripheral blood Treg cell level(P＜0.05).The level of serum MSTN was positively correlated with the level of Th17 cells and Th17/Treg in peripheral blood(P＜0.05),and negatively correlated with the level of Treg cells in peripheral blood(P＜0.05).Conclusion The incidence of OP in RA patients with SA is high.At the same time,the occurrence of SA and OP can lead to the decrease of serum 25-(OH)D3,peripheral blood Th17 cell,Th17/Treg and ASMI,and the increase of serum MSTN and peripheral blood Treg cell.The combination detection of 25-(OH)D3,MSTN and ASMI can effectively improve the diagnosis of OP in RA patients with SA,and the levels of the three are significantly correlated with peripheral blood Th17 cells,Treg cells and Th17/Treg.

Objective:To systematically evaluate the incidence and risk factors of acute kidney injury (AKI) induced by vancomycin in pediatric patients.Methods:Databases of PubMed, Embase, The Cochrane Library, Web of Science, CNKI, Wanfang, VIP, Chinese Biomedical Database (CBM) were searched and articles about the risk factors of AKI induced by vancomycin in pediatric patients from inception to June 2024 were collected. Quality assessment was performed using the Newcastle-Ottawa Scale (NOS) for the included studies. Meta-analysis of the data for relevant exposure factors extracted from the included literature was conducted using Rev Man 5.4. The strength of association between the exposure factors and AKI was expressed using the odds ratio ( OR) and its 95% confidence interval ( CI). Results:A total of 13 studies were entered, involving 11 073 patients. Of them, 1 388 patients were in AKI group and 9 685 patients in non-AKI group. The incidence of AKI was 12.53%, ranging from 4.62% to 27.07%. The quality evaluation results showed that the 13 documents were all of high-quality (NOS score ≥7 points). Meta-analysis showed that admission to intensive care unit (ICU) ( OR=2.39, 95% CI: 1.59-3.59, P<0.001), vancomycin using time ≥7 d ( OR=2.19, 95% CI: 1.44-3.34 P=0.003), vancomycin steady-state trough concentration ≥15 mg/L ( OR=2.98, 95% CI: 2.22-4.01, P<0.001), combined with nephrotoxic drugs ≥2 kinds ( OR=2.92, 95% CI=1.84-4.64, P<0.001), combined with piperacillin sodium and tazobactam sodium ( OR=2.71, 95% CI: 1.72- 4.27, P<0.001), combined with carbapenem ( OR=2.36, 95% CI: 1.36-4.10, P=0.002), combined with aminoglycosides ( OR=1.78, 95% CI: 1.35-2.35, P<0.001), combined with loop diuretics ( OR=3.16, 95% CI: 2.36- 4.23, P<0.001), combined with amphotericin B ( OR=2.26, 95% CI: 1.35-3.79, P=0.002), combined with contrast medium ( OR=2.34, 95% CI: 1.04-5.25, P=0.040), and combined with aciclovir ( OR=1.74, 95% CI: 1.04-2.84, P=0.030) were all risk factors of AKI induced by vancomycin in pediatric patients. Conclusions:The incidence of vancomycin-related AKI in pediatric patients was 12.53%. Admission to ICU, vancomycin trough concentration ≥15 mg/L, medication time ≥7 d, and concomitant use of ≥2 nephrotoxic drugs and etc.were risk factors of vancomycin-related AKI.

In recent years,the incidence of childhood cancer has shown a steady upward trend.Due to the unique nature of this disease,the issue of affiliate stigma among primary caregivers of children with cancer has gradually drawn attention.Affiliate stigma not only directly affects caregivers' mental health and quality of life,but also leads to reduced social support and lower self-efficacy,thereby impacting their engagement in the caregiving process and affecting the treatment adherence and prognosis of children with cancer indirectly.This article provides a review covering 5 main areas:the conceptual definition of affiliate stigma,measurement tools,influencing factors,intervention strategies,and insights and recommendations,to provide a theoretical basis and guidance for subsequent research and the development of interventions.

OBJECTIVE: To investigate the current status of early pain and agitation management in critically ill patients in Guizhou Province. METHODS: A retrospective study was performed using data collected from a quality control activity conducted between April and June 2021 in non-provincial public hospitals with general intensive care unit (ICU) in Guizhou Province. Hospital-level data included hospital name and grade, ICU staffing, and number of ICU beds. Patient-level data included characteristics of patients treated in the general ICU on the day of the survey (e.g., age, sex, primary diagnosis), as well as pain and agitation assessments and the types of analgesic and sedative medications administered within 24 hours of ICU admission. RESULTS: A total of 947 critically ill ICU patients from 145 hospitals were included, among which 104 were secondary-level hospitals and 41 were tertiary-level hospitals. Within 24 hours of ICU admission, 312 (32.9%) critically ill patients received pain assessments, and 277 (29.3%) received agitation assessments. Among the pain assessment tools, the critical care pain observation tool (CPOT) was used in 44.2% (138/312) of critically ill ICU patients, with a significantly higher usage rate in tertiary hospitals compared to secondary hospitals [52.3% (69/132) vs. 38.3% (69/180), P < 0.05]. The Richmond agitation-sedation scale (RASS) was used in 93.8% (260/277) of critically ill ICU patients for agitation assessment, with no significant difference between hospital levels. Among the 947 critically ill patients, 592 (62.5%) received intravenous analgesics within 24 hours, with remifentanil being the most commonly used [42.9% (254/592)]; 510 (53.9%) received intravenous sedatives, with midazolam being the most frequently used [60.8% (310/510)]. Mechanical ventilation data were available for 932 critically ill patients, of whom 579 (62.1%) received mechanical ventilation and 353 (37.9%) did not. Compared with non-ventilated patients, ventilated patients had significantly higher rates of analgesic and sedative use [analgesics: 77.9% (451/579) vs. 38.8% (137/353); sedatives: 71.8% (416/579) vs. 25.8% (91/353); both P < 0.05]. In terms of analgesic selection, ventilated patients were more likely to receive strong opioids than non-ventilated patients [85.8% (95/137) vs. 69.3% (387/451), P < 0.05]. For sedatives, ventilated patients preferred midazolam [66.6% (277/416)], whereas non-ventilated patients more often received dexmedetomidine [45.1 (41/91)]. Blood pressure within 24 hours of ICU admission were available for 822 critically ill patients, of whom 245 (29.8%) had hypotension and 577 (70.2%) did not. Compared with non-hypotensive patients, hypotensive patients had significantly higher rates of analgesic and sedative use [analgesics: 74.7% (183/245) vs. 59.8% (345/577); sedatives: 65.7% (161/245) vs. 51.3% (296/577); both P < 0.05], but there was no significant difference in the choice of analgesic or sedative agents between the two groups. CONCLUSIONS The proportion of critically ill ICU patients in Guizhou Province who received standardized pain and agitation assessments was relatively low. The most commonly used assessment tools were CPOT and RASS, while remifentanil and midazolam were the most frequently used analgesic and sedative agents, respectively. Secondary-level hospitals had a lower rate of using standardized pain assessment tools compared to tertiary-level hospitals. Mechanical ventilation and hypotension were associated with the use of analgesic and sedative medications.

To develop vaccines for the prevention and control of porcine circovirus 2d genotype(PCV2d)and pseudorabies virus(PRV),the PCV2d ORF2 gene was amplified by PCR,and cloned into the BamH Ⅰ site of PRV transfer plasmid pG vector harboring the enhanced green fluorescent protein(EGFP)gene.The resulting recombinant transfer plasmid pG-PCV2d-EGFP was transfect-ed into ST cells infected with the three gene deleted PRV variant strain gE-/g-/TK-PRV NY to generate a recombinant virus rPRV-PCV2d-EGFP+,and then the EGFP gene was knocked out to harvest the rPRV-PCV2d using gene-editing technology termed CRISPR/Cas9 system.The recom-binant virus rPRV-PCV2d had similar genetic stability to the parental PRV as indicated by PCR and one-step growth curve test,and the expression of PCV2d capsid(Cap)protein was validated by Western blot.In animal experiment,higher PCV2-specific ELISA antibodies and detectable PCV2-specific neutralizing antibodies could be elicited in mice immunized with the recombinant vi-rus rPRV-PCV2d compared to commercial PCV2 inactivated vaccine.rPRV-PCV2d significantly re-duced the PCV2d loads in tissues such as the heart,liver and spleen of mice following virulent PCV2d challenge.Moreover,rPRV-PCV2d elicits PRV-specific immune responses in mice and can prevent PRV virulent infection in mice,indicating the recombinant virus rPRV-PCV2d has strong immunogenicity.
