[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

With the widespread use of antibiotics, drug-resistant bacterial infections have become a significant threat to human health. Finding new antibacterial strategies that can effectively control drug-resistant bacterial infections has become an urgent task. Unlike small molecule drugs that target bacterial proteins, antisense oligonucleotide (ASO) can target genes related to bacterial resistance, pathogenesis, growth, reproduction and biofilm formation. By regulating the expression of these genes, ASO can inhibit or kill bacteria, providing a novel approach for the development of antibacterial drugs. To overcome the challenge of delivering antisense oligonucleotide into bacterial cells, various drug delivery systems have been applied in this field, including cell-penetrating peptides, lipid nanoparticles and inorganic nanoparticles, which have injected new momentum into the development of antisense oligonucleotide in the antibacterial realm. This review summarizes the current development of small nucleic acid drugs, the antibacterial mechanisms, targets, sequences and delivery vectors of antisense oligonucleotide, providing a reference for the research and development of antisense oligonucleotide in the treatment of bacterial infections.

Background::Differentiated thyroid cancer (DTC) is commonly diagnosed in women of child-bearing age, but whether pregnancy influences the prognosis of DTC remains controversial. This study aimed to summarize existing evidence regarding the association of pregnancy with recurrence risk in patients previously treated for DTC.Methods::We searched PubMed, Embase, Web of Science, Cochrane, and Scopus based on the prespecified protocol registered at PROSPERO (CRD42022367896). After study selection, two researchers independently extracted data from the included studies. For quantitative data synthesis, we used random-effects meta-analysis models to pool the proportion of recurrence (for pregnant women only) and odds ratio (OR; comparing the risk of recurrence between the pregnancy group and the nonpregnancy group), respectively. Then we conducted subgroup analyses to explore whether risk of recurrence differed by response to therapy status or duration of follow-up time. We also assessed quality of the included studies.Results::A total of ten studies were included. The sample size ranged from 8 to 235, with participants’ age at pregnancy or delivery ranging from 28 to 35 years. The follow-up time varied from 0.1 to 36.0 years. The pooled proportion of recurrence in all pregnant patients was 0.13 (95% confidence intervals [CI]: 0.06-0.25; I2: 0.58). Among six included studies reporting response to therapy status before pregnancy, we observed a trend for increasingly higher risk of recurrence from excellent, indeterminate, and biochemically incomplete to structurally incomplete response to therapy ( Ptrend <0.05). The pooled risk of recurrence in the pregnancy group showed no evidence of a significant difference from that in the nonpregnancy group (OR: 0.75; 95% CI: 0.45-1.23; I2: 0). The difference in follow-up time (below/above five years) was not associated with either the proportion of recurrence in all pregnant patients ( P >0.05) or the OR of recurrence in studies with a comparison group ( P >0.05). Two included studies that focused on patients with distant metastasis also did not show a significant difference in disease recurrence between pregnancy and nonpregnancy groups (OR: 0.51 [95% CI: 0.14-1.87; I2: 59%]). Conclusion::In general, pregnancy appears to have a minimal association with the disease recurrence of DTC with initial treatment. Clinicians should pay more attention to progression of DTC among pregnant women with biochemical and/or structural persistence.Registration::PROSPERO, https://www.crd.york.ac.uk/PROSPERO/; No. CRD42022367896.

Objective To investigate the effect of long non-coding RNA(lncRNA)antisense transcript of SATB2 protein(SATB2-AS1)on the biological function of lung adenocarcinoma cells and its mechanism.Methods Tumor tissues and adjacent tissues from 25 patients with lung adenocarcinoma were collected to detect the expression of SATB2-AS1.Then,the overexpression vector of lncRNA SATB2-AS1(pcDNA-SATB2-AS1)and shRNA or shRNA of IGF2BP2(sh-SATB2-AS1;sh-IGF2BP2)and/or shRNA of SLC7A11(sh-SLC7A11)were transfected into lung adenocarcinoma cell A549.RIP assay was used to estimate the binding of IGF2BP2 protein to SATB2-AS1 or SLC7A11 mRNA,respectively;CCK-8 and Transwell assay were used to detect the proliferation and invasion ability of lung adenocarcinoma cells;RT-qPCR and Western blot assay were used to detect gene expression and protein expression,respectively.Results Compared with adjacent tissues and human bronchial epithelial cell BEAS-2B,the expression of SATB2-AS1 was significantly down-regulated in tumor tissues of patients with lung adenocarcinoma and lung adenocarcinoma cells(P<0.01).Overexpression of SATB2-AS1 significantly inhibited the proliferation and invasion of A549 cells,while silencing SATB2-AS1 significantly promoted the cell proliferation and invasion(P<0.05).Moreover,overexpression of SATB2-AS1 significantly reduced Fe2+concentration,reactive oxygen species(ROS)level,and malondialdehyde(MDA)content in A549 cells(P<0.01),and increased glutathione(GSH)content,the expression of SLC7A11 and GPX4 which were the key proteins of ferroptosis(P<0.01).Meanwhile,SATB2-AS1 significantly promoted IGF2BP2 protein binding to SLC7A11 mRNA by binding to IGF2BP2 protein,and reduced the stability of SLC7A11 mRNA(P<0.01).Silencing SLC7A11 significantly reversed the effects of silencing SATB2-AS1 on A549 cells.Conclusion LncRNA SATB2-AS1 destabilizes SLC7A11 mRNA by recruiting IGF2BP2 protein,induces the ferroptosis of lung adenocarcinoma cells,inhibits the cell proliferation and invasion,and thus inhibits the progression of lung adenocarcinoma.

N6-methyladenosine(m6A)modification involves the methylation of the sixth nitrogen atom on the base A of RNA molecules.It is the most common and abundant RNA epigenetic modification in eukaryotic organism.It could not only directly affect the transcriptional level of intracellular genome,but also regulate the expression level of oncogenes,tumor suppressor genes and some ncRNA genes.Additionally,some autophagy-related genes and ferroptosis metabolism pathway-related genes were also reported to be regulated by m6A.The abnormal regulation and dysfunction of target genes by m6A usually promote or inhibit the growth of tumor cells.Therefore,the regulation of cellular autophagy and ferroptosis by m6A to affect the growth of tumor was summarized in the study.It will be useful to demonstrate the mechanism of tumorigenesis and provide scientific basis for the development of a novel target on the treatment of tumor.

Objective:To investigate the prognostic value of minimal residual disease(MRD)detected by multi-parameter flow cytometry(MFC)in pediatric patients with acute myeloid leukemia(AML)after induction chemotherapy.Methods:A retrospective study was conducted on 97 pediatric patients initially diagnosed with AML at Wuhan Children's Hospital from August 2015 to December 2022.The study analyzed the results of MRD detection using MFC after the first and second cycles of induction chemotherapy,and its association with prognosis were analyzed.Results:Following the first cycle of induction treatment,57 of the 97 patients tested positive for MRD(MRD1+,58.8%).Subsequently,19 patients remained MRD positive(MRD2+,19.6%)after the second cycle of induction treatment.Kaplan-Meier survival analysis showed that the estimated 3-year overall survival(OS)rate of the 37(64.9%)MRD1+patients who underwent transplantation was significantly higher than that of the 20(35.1%)MRD1+patients who did not undergo transplantation(84.6%vs 40.0%,P=0.0001).Among the 35 MRD1+MRD2-patients,the 3-year OS rate of the 25 children who underwent transplantation was higher than that of the 10 children who did not undergo transplantation(87.2%vs 70.0%,P=0.3229).The 3-year OS rate of the 19 MRD1+MRD2+patients was lower than that of the 35 MRD1+MRD2-patients(57.4%vs 81.8%,P=0.059).In the 19 MRD2+patients,the 3-year OS rate of the 12 children who underwent transplantation was significantly higher than that of the 7 children who did not undergo transplantation(80.8%vs 14.3%,P=0.0007).There was no significant difference in 3-year OS between the 12 MRD1+MRD2+patients and 25 MRD1+MRD2-patients,both treated with transplantation(80.8%vs 87.2%,P=0.8868).In those not treated with transplantation,the 7 MRD1+MRD2+patients had a significantly lower 3-year OS compared with the 10 MRD1+MRD2-patients(14.3%vs 70.7%,P=0.0114).Further multivariate analysis indicated that MRD2 positivity and transplantation were both independent prognostic factors(P=0.031,0.000),while MRD1 positivity was not significantly associated with the overall prognosis of 97 patients(P=0.902).Conclusion:MRD positivity following the second cycle of induction chemotherapy is an independent risk factor for unfavorable outcomes in children with AML.MRD2 positivity indicates a poorer prognosis and can help to identify the candidates requiring transplantation.MRD2 positivity is not a contraindication for transplantation in pediatric patients,and early transplantation significantly improves the prognosis of high-risk patients.
