Objective: To explore the key factors affecting the selection and effectiveness of bladder management modalities in patients with spinal cord injury，so as to provide reference for the optimization of individualized bladder management strategies. Methods: The clinical and follow-up data of 78 patients with spinal cord injury treated in our hospital during Jan.1,2013 and Dec.31,2022 were retrospectively analyzed.The distribution of bladder management modalities among different grades of injuries was analyzed. Bowker symmetry test was used to evaluate the difference between bladder management modalities at discharge and at the end of follow-up. Multiple linear regression was used to explore the influencing factors of bladder management effects. Plotting Kaplan-Meier survival curves were adopted to calculate the median time of changes in bladder management. Results: At discharge，there were 9 cases of self-catheterization，19 cases of intermittent catheterization，22 cases of reflexive voiding，26 cases of long-term catheterization，and 2 cases using urinary collector.At the end of follow-up，there were 15 cases of self-catheterization，8 cases of intermittent catheterization，34 cases of reflexive voiding，14 cases of long-term catheterization，and 7 cases using urinary collector.There was a significant difference between the modalities of bladder management at discharge and at the end of follow-up (χ =21.43，P=0.018).Multiple linear regression showed a significant decrease of 8.60 in the total neurogenic bladder symptom score (NBSS) for grade D injuries compared with grade A injuries (P=0.026). The median time to bladder management change was 7.93 months (95%CI:5.44-9.44), with approximately 50% of patients experiencing a change in bladder management within 8 months after discharge. Conclusion: The modalities of bladder management changed significantly after discharge.The grade of injury was a key factor affecting the effectiveness of bladder management.Higher grade was associated with worse effectiveness of bladder management.

Objective: Previous observational studies have confirmed the correlation between gut microbiota and bladder cancer，but the causal relationship is still unclear.This study aimed to explore the causal relationship between them with Mendelian randomization. Methods: Genetic variation summary data of 211 gut microbiota and bladder cancer genome-wide association studies (GWAS) were obtained from the MiBioGen Consortium and Finngen database.Single nucleotide polymorphisms (SNPs) closely related to these studies were screened as instrumental variables.The causal relationship between gut microbiota and bladder cancer were analyzed with inverse variance weighting (IVW)，MR-Egger，weighted median，maximum likelihood，robust adjustment feature score and MR-PRESSO，with IVW as the primary analysis method.Additionally，sensitivity analysis was used to test the heterogeneity (Cochran Q) and horizontal pleiotropy (MR-Egger intercept term and global test from MR-PRESSO estimator) to ensure the robustness of the results. Results: The IVW results indicated that Lachnospiraceae UCG004 (OR：1.42)，Desulfovibrionales (Order) (OR：1.48)，Eubacterium ruminantium group (OR：1.33)，Olsenella (OR：1.24)，Ruminococcaceae UCG002 (OR：1.39)，Ruminococcaceae UCG005 (OR：1.42) and Ruminococcaceae UCG013 (OR：1.64) significantly increased the risk of bladder cancer.Conversely，Bacteroidetes (Phylum) (OR：0.61)，Eubacterium brachy group (OR：0.80)，Ruminococcaceae UCG004 (OR：0.73)，Rikenellaceae (Family) (OR：0.67)，Lachnospiraceae ND3007 group (OR：0.47), Adlercreutzia (OR：0.73) and an unknow genus (OR：0.75) were associated with a reduced risk of bladder cancer.Sensitivity analyses did not reveal any heterogeneity or horizontal pleiotropy. Conclusion: This study reveals the causal role of 14 gut microbiota in the pathogenesis of bladder cancer，among which Lachnospiraceae UCG004，Desulfovibrionales (Order)，Eubacterium ruminantium group，Olsenella，Ruminococcaceae UCG002，Ruminococcaceae UCG005 and Ruminococcaceae UCG013 are risk factors for bladder cancer，while Bacteroidetes (Phylum)，Eubacterium brachy group，Ruminococcaceae UCG004，Rikenellaceae (Family)，Lachnospiraceae ND3007 group，Adlercreutzia and an unknown genus are the protective factors.

Objective To compare the clinical efficacy of transperineal prostate laser ablation(TPLA)and transurethral resection of the prostate(TURP)in the treatment of benign prostatic hyperplasia(BPH).Methods A total of 60 BPH patients diagnosed during Oct.2021 and Oct.2022 at Tangdu Hospital were selected as the research subjects and randomly divided into the TPLA group(n=30)and TURP group(n=30).The intraoperative bleeding volume,operation time,catheter indwelling time,length of hospital stay,postoperative sexual dysfunction,and surgical related complications were compared between the two groups.The international prostate symptom score(IPSS),international index of erectile function-5(IIEF-5),maximum urinary flow rate(Qmax),quality of life score(QoL),postvoid residual(PVR)and prostate volume(PV)were compared between the two groups before surgery and 1,3,and 12 months after surgery.Results The TPLA group had significantly less intraoperative bleeding volume,shorter operation time and length of hospital stay compared to the TURP group,but longer catheter indwelling time(P＜0.05).Both groups showed significant improvement in IPSS and Qmax 1,3,and 12 months postoperatively compared to preoperative(P＜0.05),the IPSS of the TPLA group was significantly higher than that of the TURP group 1 and 3 months after surgery(P＜0.05);the Qmax of TPLA group 1,3,and 12 months after surgery was lower than that of the TURP group(P＜0.05).The IIEF-5 score was significantly better in the TPLA group than in the TURP group after surgery(P＜0.05).The postoperative QoL,PV,and PVR levels in both groups improved after surgery(P＜0.05),the QoL of the TPLA group was lower than that of the TURP group 1 and 12 months after surgery(P＜0.05),the PV and PVR of the TPLA group were higher than those of the TURP group 1,3,and 12 months after surgery(P＜0.05).The incidence of surgery-related complications(3.33％vs.26.67％)and postoperative sexual dysfunction(3.33％vs.36.67％)in the TPLA group were lower than those in the TURP group(P＜0.05).Conclusion TPLA shows significant efficacy in treating BPH with minimal impact on the sexual function.It provides a new approach for BPH patients and can serve as an effective complementary method in clinical practice.

OBJECTIVE: To depict the cell landscape and molecular biological characteristics of human intrauterine adhesion (IUA) so as to better understand its immune microenvironment and provide new inspirations for clinical treatment. METHODS: Four patients with IUA who underwent hysteroscopic treatment at Dongguan Maternal and Child Health Care Hospital from February 2022 to April 2022 were selected as the study subjects. Hysteroscopy was used to collect the tissues of IUA, which were graded based on the patient's medical history, menstrual history and status of IUA. Library construction, sequencing, single cell data comparison and gene expression matrix construction were carried out in strict accordance with the single cell RNA sequencing process. Thereafter, the UMAP dimension reduction analysis of cell population and genetic analysis were carried out based on the cell types. RESULTS: A total of 27 511 cell transcripts were obtained from four moderately graded IUA tissue samples and assigned to six cell lineages including T cells, mononuclear phagocytes, epithelial cells, fibroblasts, endothelial cells and erythrocytes. Compared with normal uterine tissue cells, the four samples showed different cell distribution, and the proportions of mononuclear phagocytes and T cells in sample IUA0202204 were significantly increased, suggesting a strong cellular immune response. CONCLUSION The cell diversity and heterogeneity of moderate IUA tissues have been described. Each cell subgroup has unique molecular characteristics, which may provide new clues for further study of the pathogenesis of IUA and heterogeneity among the patients.

Objective:To evaluate the effect of small-dose furosemide on tissue edema after shoulder arthroscopy.Methods:A total of 368 patients of either sex, aged 18-65 yr, of American Society of Anesthesiology physical status Ⅰ orⅡ, were divided into 2 groups ( n=184 each) by a random number table method: control group (group C) and small-dose furosemide group (group F). A posterior approach to interscalene brachial plexus block was selected, tracheal intubation was performed under general anesthesia, and all the patients were placed in the lateral position.At 20-30 min before the end of surgery, patients in group F received intravenous injection of furosemide 2 mg (diluted to 2 ml in normal saline) and patients in group C received intravenous injection of normal saline 2 ml.The tissue thickness from the surface of the second rib of the middle clavicular line to the skin (CR2) was measured by ultrasound immediately after nerve block (T 0), immediately after tracheal intubation (T 1), immediately after the end of operation (T 2), and at 30 min and 1, 4 and 8 h after operation (T 3-6). Arterial blood gas analysis was performed at T 1-3, Hct and blood glucose concentration were measured simultaneously, and relative blood volume was calculated.Tube malposition at T 2 and hypoxemia within 30 min after operation were recorded. Results:Compared with the baseline at T 0, CR2 on the affected side was significantly increased at T 2-5 in group F, and CR2 on the affected side was significantly increased at T 2-6 in group C ( P<0.05). CR2 at T 2-5 was significantly higher on the affected side than on the healthy side ( P<0.05). Compared with group C, intraoperative urine volume was significantly increased, CR2 was decreased at T 2-5, the incidence of tube malposition and hypoxemia was decreased ( P<0.05), and no significant changes were found in pH value, PaO 2, PaCO 2, Na + , K + , Ca 2+ , Cl -, blood glucose concentration or relative blood volume at each time point in group F ( P>0.05). Conclusion:Small-dose furosemide can reduce tissue edema after shoulder arthroscopy and decrease the occurrence of postoperative tube malposition and hypoxemia, without causing disturbances in the internal environment.

Objective: To make a preliminary assessment on the immunogenicity of a quadrivalence recombinant human papillomavirus (HPV) vaccine (6, 11, 16 and 18 types) (Hansenulapolymorpha) in healthy women aged 18-45 years in phaseⅠclinical study. Methods: It was a single-center, double-blind, randomized, placebo-controlled phaseⅠ clinical study. Women aged 18-45 years were randomized (2∶1) to receive HPV vaccine (n=60) or placebo control (n=30) at months 0, 2 and 6. Antibodies against HPV6/11/16/18 were detected by pseudovirus-based neutralisation assay in serum samples collected at 0 d, 180 d and 210 d. Seroconversion rates and geometric mean titres (GMT) of antibodies against the four types of antigens were calculated. Results: Seroconversion rates of the vaccination group at 180 d (before the third dose) and 210 d (one month after the third dose) were generally similar and between 85%-100% for all types of antibodies. The GMT of antibodies at one month after the last dose improved significantly compared with those before immunization. Conclusions These results showed that the HPV vaccine had good immunogenicity in the population of healthy women aged 18-45 years. Higher antibody titers were elicited by the vaccine compare with the tites before the first dose and in the placebo control group.

Objective To investigate the relationship between TGFβ1-509 C/T, TCRCα-575 A/G SNPs and primary AAV using a transmission disequilibrium theory based pedigree analysis Methods Genotypes of 264 individuals from 88 AAV families include patients, their parents, brothers and sisters were determined by PCR-RFLP and direct sequencing. Transmission disequilibrium test(TDT) and HRR were employed for the data analysis to observe the transmission disequilibrium of TGF31-509 C/T and TCRCα -575 A/G polymorphisms. Results No transmission disequilibrium from heterozygous parents onto the patients was found in the trios analyzed by TDT for either TGFβ1-509 C/T (observed C/T = 36/28, expected C/T =33. 5/30. 5, x2 =0.51, P＞0.05) or TCRCo-575 A/G ( observed A/G = 29/39, expected A/G = 33.5/34. 5, x2 = 1. 59, P ＞ 0. 05 ). The genotype-based HRR and haplotype-based HRR showed there was no increased risk of AAV in the observed trios for either -509 C/T polymorphism of TGFβ1 (transmitted genotype CC/CT/TT =12/20/6, allele C/T = 44/32; nontransmitted genotype CC/CT/TT = 10/19/9,allele C/T =39/37, genotype-based HRR x2 =0.81, P ＞0. 05, haplotype-based HRR x2 =0. 66, P＞0. 05,HRR = 1.30) or -575 A/G polymorphism of TCRCα ( transmitted genotype AA/AG/GG = 9/18/12, allel A/G = 36/42; nontransmitted genotype AA/AG/GG = 15/15/9, allel A/G = 35/33, genotype-based HRR x2=2. 20, P ＞0. 05. Haplotype-based HRR x2 =0. 41, P ＞0. 05, HRR =0. 81 ). The deviation of HRR coefficient was not excessive(1.00). Conclusion TGFβ1-509 C/T and TCRCo-575 A/G polymorphism may not be associated with the genetic susceptibility of primary AAV in Guangxi Han population.
