Objective:To analyze the influence factors of urinary tract infection after transurethral bipolar plasma enucleation of the prostate (TUPEP) in patients with benign prostatic hyperplasia(BPH), and the early predictive value of serum inflammatory indicators for postoperative urinary tract infection.Methods:A total of 300 patients with BPH who received TUPEP treatment in the Department of Urology, Kailuan General Hospital from January 2021 to August 2023 were selected, according to whether they had urinary tract infections after the operation, they were divided into infection group ( n=117) and non-infection group ( n=183). The clinical data of the two groups were collected, and the serum inflammatory indexes of the two groups were recorded within 24 hours after the operation, including white blood cell count (WBC), neutrophil granulocyte (NE%), high-sensitivity C-reactive protein (hs-CRP), serum amyloid A (SAA), procalcitonin (PCT), heparin-binding protein (HBP), interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), and serum ferritin (SF). The differences of clinical data and serum inflammatory indexes between the two groups were analyzed. The measurement data of normal distribution were expressed as mean ± standard deviation ( ± s), and independent sample t-test was used for inter-group comparisons. The measurement data of non- normal distribution were represented by median (interquartile range) [ M ( Q1, Q3)], and the Mann-Whitney U test was used for inter-group comparison. The count data were expressed as cases and percentage, and inter-group comparisons were conducted using the Chi-test. Multivariate Logistic regression analysis was used to explored the influencing factors of urinary tract infections in BPH patients after TUPEP surgery. The receiver operating characteristic (ROC) curve was plotted using GraphPad Prism 8.0.1 medical plotting softwar to evaluate the predictive value of serum inflammatory markers and combined detection of multiple markers for early postoperative urinary tract infections. Results:The duration of disease, history of diabetes, international prostate symptom score (IPSS), prostate volume, preoperative serum prostate-specific antigen (PSA) level, preoperative urine residual volume, operation time, intraoperative blood loss, postoperative catheter indwelling time, and hospitalization time in the infection group were higher than those in the non-infection group ( P<0.05). The preoperative 25-hydroxyvitamin D (25OHD) level and maximum urinary flow rate were lower in the infection group than those in the non- infection group ( P<0.05). Multivariate Logistic regression analysis showed that the course of the disease, history of diabetes, IPSS score, prostate volume, preoperative PSA level, preoperative urine residual volume, operation time, intraoperative blood loss, postoperative catheter indwelling time was positively correlated with urinary tract infection after TUPEP ( B=0.660, 0.242, 0.164, 0.125, 0.230, 0.066, 0.382, 0.022, 0.436, P<0.01), and preoperative 25OHD level and preoperative maximum urinary flow rate were negatively correlated with urinary tract infection after TUPEP ( B=-0.216, -0.372, P<0.01). The levels of hs-CRP, SAA, PCT, HBP, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α, IFN-γ, SF in the infection group were higher than those in the non-infection group ( P<0.001). The ROC curve analysis showed that the area under the curve (AUC) of hs-CRP, SAA, PCT, HBP, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α, IFN-γ, SF in early predicting urinary tract infection after TUPEP in BPH patients were 0.697, 0.775, 0.902, 0.873, 0.884, 0.904, 0.917, 0.823, 0.906, 0.852, 0.807, 0.787. The AUC of the combined detection of multiple serum inflammatory markers was 0.972, the sensitivity and specificity were 93.18% and 96.63%, and the sensitivity and specificity of the combined detection of multiple serum inflammatory markers were higher than those of separate detection. Conclusion:The course of BPH, whether to combine history of diabetes, preoperative IPSS score, prostate volume, preoperative PSA level, preoperative 25OHD level, preoperative maximum urinary flow rate, operation time, intraoperative blood loss, and postoperative catheter indwelling time are influencing factors of urinary tract infection after TUPEP, hs-CRP, SAA, PCT, HBP, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α, IFN-γ, SF had certain value in the early prediction of urinary tract infection after TUPEP in patients with BPH, the combination of multiple indicators can improve the predictive value of early urinary tract infection.

Getah virus(GETV)is an arbovirus capable of infecting humans and vertebrates such as horses and pigs via blood-sucking mosquitoes,which is extremely harmful to the livestock indus-try.Current monitoring methods are time-consuming,costly,and dependent on specialized instru-ments.These characteristics hinder rapid detection in clinical samples.Therefore,the development of a simple,rapid,specific,and sensitive method for detecting GETV antigen is crucial for the pre-vention and control of GETV.In this study,a GETV E1 monoclonal antibody strain SD17/09-E1-mAb was prepared by a prokaryotic expression system for GETV E1 protein expression,and a col-loidal gold double-antibody sandwich assay encapsulating two strains of GETV E1 monoclonal an-tibody wasestablished.The results showed that the prepared colloidal gold test strips had good sen-sitivity and did not cross-react with other common porcine virus-positive tissue samples;the test strips had a high compliance rate with the IFA assay for GETV,and could be stored at 37 ℃ for one month and at room temperature for at least three months.In this study,a colloidal gold anti-surveillance test strip for rapid detection of GETV was successfully prepared,which provides a powerful tool for GETV detection.

Objective:To systematically evaluate and integrate the exercise experience of overweight or obese pregnant women during pregnancy, in order to provide basis for the formulation of standardized exercise programs for this population.Methods:We searched databases including PubMed, Cochrane Library, Web of Science, CINAHL, Embase, Ovid, PsycINFO, Chinese Biomedical Literature Database, VIP, Wanfang and China National Knowledge Infrastructure, from their inception to August 16, 2023, to collect qualitative studies on the exercise experience of overweight or obese pregnant women during pregnancy.

Objective To explore the characteristics and mechanism of phase separation between TAR DNA binding protein-43(TDP-43)and ubiquitin.Methods The TARDBP gene and its truncated genes were inserted into vectors to construct recombinant plasmids for expression and protein purification.The phase separation system of ubiquitin and TDP-43 was constructed in vitro.The characteristics of the droplets formed via liquid-liquid phase separation were observed by fluorescence microscopy.The plasmids of ubiquitin and TDP-43 were co-transfected into HEK293T cells to observe aggregates containing TDP-43 and ubiquitin and find out whether TDP-43 could be ubiquitinated.Results The GFP-8Ub,TDP-43 full-length(FL)and truncated proteins were purified.TDP-43 FL and C-terminal domain(CTD)proteins were able to form droplets via phase separation with ubiquitin.The droplets changed into solid-like aggregates after prolonged incubation.Insolvable aggregates containing TDP-43 and ubiquitin were formed.TDP-43 was ubiquitinated under stress conditions in HEK293T cells after being co-transfected with ubiquitin and TDP-43 recombinant plasmids.Conclusion TDP-43 undergoes co-phase separation with ubiquitin,mainly driven by the multivalent interaction between TDP-43′s CTD structural domain and ubiquitin.The droplets finally form aggregates with solid-like properties.Under stress conditions,especially when the protein homeostasis is disrupted,TDP-43 and ubiquitin form aggregates while TDP-43 is ubiquitinated.This study reveals the basic mechanism of TDP-43 co-phase separation with ubiquitin and liquid-solid transformation.

Objective:To explore the expression relationship and significance of long chain non-coding RNA nuclear-enriched abundant transcript 1(LncRNA NEAT1)and miR-27a-3p in serum and cerebro-spinal fluid of patients with Alzheimer disease(AD).Methods:Sixty-six AD patients received by the department of neurology of our hospital from October 2019 to September 2021 were gathered,according to the clinical dementia rating scale score,they were grouped into mild group(≤ 1 point,n=41)and moderate-to-severe group(＞1 point,n=25).Another 66 cases of serum and cerebrospinal fluid sam-ples from outpatient physical examination personnel were regarded as the control group.The general infor-mation on all subjects was recorded and cognition was assessed;real-time quantitative PCR was performed to measure the expression levels of miR-27a-3p and NEAT1 in serum and cerebrospinal fluid;enzyme-linked immunosorbent assay was performed to measure the protein levels of β-amyloid precursor protein cleaving enzyme 1(BACE1),β-amyloid(Aβ)40 and Aβ42 in cerebrospinal fluid;Spearman's method was performed to analyze the correlation of serum miR-27a-3p and NEAT1 levels with mini-mental state examination(MMSE)and montreal cognitive assessment(MoCA)scores;Pearson method was per-formed to analyze the correlation between serum miR-27a-3p and NEAT1 levels and Aβ deposition standard uptake value ratio(SUVR)and cerebrospinal fluid miR-27a-3p,NEAT1,BACE1,Aβ42 and Aβ40 levels.Results:The MMSE score[21(17,25),9(7,11)vs.27(21,34)],MoCA score[17(12,21),10(7,13)vs.27(21,31)],serum miR-27a-3p level(0.55±0.13,0.46±0.06 vs.0.97± 0.22),cerebrospinal fluid miR-27a-3p(0.48±0.10,0.35±0.10 vs.1.03±0.31),Aβ42 levels[(303.55±36.77)ng/L,(231.45±34.14)ng/L vs.(499.99±53.63)ng/L]and Aβ42/Aβ40 ra-tio(0.030±0.008,0.022±0.007 vs.0.048±0.010)of AD patients in mild group and moderate-to-severe group were all lower than those in the control group,and the moderate-to-severe group were lower than the mild group(all P＜0.05);the serum NEAT1 level(2.31±0.64,3.13±0.76 vs.1.05± 0.20),SUVR(1.50±0.29,1.76±0.52 vs.0.74±0.15),and cerebrospinal fluid NEAT1(3.51± 1.24,4.30±1.65 vs.1.01±0.23)and B ACE 1 levels[(55.78±5.98)μg/L,(72.32±16.08)μg/L vs.(21.39±3.73)μg/L]were higher than those in the control group,and the moderate-to-se-vere group were higher than the mild group(all P＜0.05).Serum NEAT1 level in AD patients was posi-tively correlated with SUVR,cerebrospinal fluid NEAT1 and BACE1(r=0.350,0.606,0.341,P＜0.05),and negatively correlated with MMSE score and MoCA score(r=-0.473,-0.482,all P＜0.05);serum miR-27a-3p level was positively correlated with cerebrospinal fluid miR-27a-3p level,MMSE score and MoCA score(r=0.695,0.424,0.412,all P＜0.05),and negatively correlated with SUVR and cerebrospinal fluid BACE1 level(r=-0.521,-0.447,all P＜0.05).Conclusion:The expression trends of NEAT1 and miR-27a-3p in the serum and cerebrospinal fluid of AD patients are con-sistent,the level of NEAT1 is increased,and the level of miR-27a-3p is decreased.The levels of the two are negatively correlated,which is related to the degree of Aβ deposition in the brain of AD patients and is involved in the progression of AD.

Objective:To explore the efficacy and safety of domestic bortezomib in combination with lenalidomide and dexamethasone in the treatment of newly diagnosed multiple myeloma (NDMM) .Methods:This multicenter, prospective, single-arm clinical study included 126 patients with NDMM admitted to seven hospitals between December 2019 and January 2022. All patients received domestic bortezomib in combination with lenalidomide and dexamethasone (BLD regimen), and the efficacy, prognostic factors, and safety were analyzed.Results:Among the 126 patients with NDMM, 118 completed four cycles of treatment, with an overall response rate (ORR) of 93.22% (110/118) and a ≥very good partial response (VGPR) rate of 68.64% (81/118). Ultimately, 114 patients completed at least eight cycles of treatment, with an ORR of 92.98% (106/114) and a ≥VGPR rate of 77.19% (88/114). Eighteen patients underwent autologous hematopoietic stem cell transplantation after completing 6-8 cycles of the BLD regimen, with an ORR of 100% (18/18) and a ≥VGPR rate of 88.9% (16/18). The proportion of patients achieving ≥VGPR increased with the treatment duration, and factors such as staging and age did not significantly affect efficacy. Single-factor analysis showed that R2-ISS stage Ⅲ/Ⅳ, blood calcium >2.27 mmol/L, and failure to achieve VGPR after six cycles were adverse prognostic factors for progression-free survival (PFS) ( P<0.05), whereas failure to achieve VGPR after six cycles was an adverse prognostic factor for overall survival (OS) ( P<0.001). Multifactor analysis demonstrated that failure to achieve VGPR after six cycles is an independent adverse prognostic factor for PFS ( P=0.002). The incidence of hematologic adverse reactions was 16.7% (19/114), and nonhematologic adverse reactions were mainly mild to moderate, with no significant cardiac or renal adverse reactions observed. Conclusion:The BLD regimen is effective in treating NDMM, in which patients with high-risk genetic features are still achieving a high ≥VGPR rate, and the overall safety is good.
