Living systematic review (LSR) is a systematic review methodology that incorporates regular updates to integrate new evidence, aiming to rapidly reflect the latest research findings. Although LSRs are increasingly adopted in clinical fields, their reporting quality remains inconsistent and lack of standardized guidelines. To standardize LSR reporting, the PRISMA 2020 statement has released an extension checklist (PRISMA-LSR). This paper describes the background of PRISMA-LSR release and main revisions, and interprets it with examples, with the goal of guiding future LSR research and enhancing reporting quality.

Objective To evaluate the efficacy and safety of modified pelvic floor reconstruction in non-nerve-sparing robot-assisted radical prostatectomy (NNS RARP) for improving postoperative urinary control. Methods A retrospective analysis was conducted on the clinical data of 79 prostate cancer patients who underwent NNS RARP at Tangdu Hospital during Jan.2020 and Dec.2023, including 29 in the reconstruction group, and 50 in the non-reconstruction group. The baseline characteristics including age, body mass index, prostate-specific antigen (PSA) level, clinical stage, prostate volume, and biopsy Gleason score, and perioperative indexes including operation time, intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins were compared between the two groups. Additionally, urinary continence function was assessed before operation and 1,3,6, and 12 months after operation using the international consultation on incontinence questionnaire-short form (ICIQ-SF) and the incontinence quality of life questionnaire score (I-QoL). Results No statistically significant differences were observed in the baseline characteristics between the two groups (P>0.05). The operation time was significantly longer in the reconstruction group than in the non-reconstruction group [ (110.24±15.08) min vs. (101.80±9.89) min, P=0.010]. There were no significant differences in intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins between the two groups (P>0.05). The reconstruction group demonstrated significantly lower ICIQ-SF scores at 1 month [ (10.17±2.16) vs. (11.56±1.66), P=0.002],3 months [ (7.62±1.29) vs. (9.52±1.80), P<0.001], and 6 months postoperatively [ (4.93±1.22) vs. (6.18± 1.67), P=0.001]compared to the non-reconstruction group (adjusted P<0.0125). Conversely, the I-QoL scores were significantly higher in the reconstruction group at 1 month [ (73.32±10.30) vs. (63.88±9.55), P<0.001]and 3 months postoperatively [ (78.91±4.82) vs. (75.66±5.17), P=0.007] (adjusted P<0.0125). However, no significant differences were found in ICIQ-SF or I-QoL scores between the two groups preoperatively and 12 months postoperatively (adjusted P>0.0125). Conclusion The application of modified pelvic floor reconstruction technique in NNS RARP is safe and feasible. Although it slightly prolongs the operation time, it does not increase surgical risks; instead, it effectively promotes early recovery of postoperative urinary continence, thereby significantly enhancing patients'quality of life.

The biotransformation processes in the human body play a crucial role in maintaining the inter-nal environment's stability by converting exogenous compounds and endogenous metabolites into substances with increased polarity or water solubility.This alteration in toxicity or pharmacological effects facilitates their excretion from the body.Sulfation,an important type of phase Ⅱ biotransformation reaction,is primarily me-diated by members of the cytosolic sulfotransferases(also known as sulfotransferases,SULTs)superfamily.Recent studies have uncovered the significant roles of SULTs in drug metabolism,tumorigenesis,inflammato-ry responses,hormone regulation,and energy metabolism.This article provides a comprehensive review of the regulatory roles and molecular mechanisms of the SULTs superfamily members in carbohydrate and lipid me-tabolism,aiming to offer new insights into the mechanism research and drug development for disorders related to carbohydrate and lipid metabolism dysregulation.

Objective:To investigate the clinical effect of progressive transfer of penile flap combined with local scrotal flap in correction of severe concealed penis in children.Methods:The clinical data of children with severe concealed penis admitted to the Children’s Hospital Affiliated to Zhengzhou University from July 2021 to July 2023 were retrospectively analyzed. The concealed penis was corrected by progressive transfer of penile flap combined with local scrotal flap. During the operation, a small amount of excess inner prepuce was removed and the outer prepuce was cut in the middle of the dorsal side of the penis. Then the penile flap was transferred from dorsal to ventral, gradually covering the wound without tension. The local scrotal flap was lifted upwards and sutured to the frenulum for covering the ventral foreskin defect of the penis. The amount of blood loss during the operation was recorded. The pain tolerance, the duration of prepuce edema, the length of penis extension and the healing of skin flap were observed. The appearance of the penis was followed up to observe whether the penis was retracted, and the satisfaction of the children and their guardians was recorded.Results:A total of 32 male children were enrolled, ranging in age from 3 to 10 years, with an average age of 7.2 years. The penis of all the children had a conical appearance, and the penile shaft was buried under the subcutaneous anterior pubis, which was difficult to palpate in its natural state. The average intraoperative blood loss was about 5 ml. All patients had pain after the operation. Two patients needed a pump to relieve pain, and the rest could tolerate it after rectum administration of indomethacin suppositories. The edema of the prepuce was mild after the operation, and the edema basically disappeared when the patient was discharged 7-9 days later. The penis could be lengthened by 1.5-3.0 cm under static conditions, averaging about 2.0 cm. After surgery, only 1 patient had a small area (about 5 mm × 4 mm) of infection in the scrotal flap and poor incision healing, and scar healing after dressing change and intensive nursing. The other flaps healed well. After 6 to 12 months of follow-up, the penis length of 2 cases was slightly retracted from the time of discharge, and the remaining 30 cases had no significant change. The patients and their guardians were satisfied with the operation results.Conclusion:The progressive transfer of penile flap combined with local scrotal flap correction of severe concealed penis in children can fully lengthen the penile body, and the degree of postoperative retraction is low, the appearance of the penis is good, and the patient satisfaction is high.

Epigenetic pathways play a critical role in the initiation, progression, and metastasis of cancer. Over the past few decades, significant progress has been made in the development of targeted epigenetic modulators (e.g., inhibitors). However, epigenetic inhibitors have faced multiple challenges, including limited clinical efficacy, toxicities, lack of subtype selectivity, and drug resistance. As a result, the design of new epigenetic modulators (e.g., degraders) such as PROTACs, molecular glue, and hydrophobic tagging (HyT) degraders has garnered significant attention from both academia and pharmaceutical industry, and numerous epigenetic degraders have been discovered in the past decade. In this review, we aim to provide an in-depth illustration of new degrading strategies (2017-2023) targeting epigenetic proteins for cancer therapy, focusing on the rational design, pharmacodynamics, pharmacokinetics, clinical status, and crystal structure information of these degraders. Importantly, we also provide deep insights into the potential challenges and corresponding remedies of this approach to drug design and development. Overall, we hope this review will offer a better mechanistic understanding and serve as a useful guide for the development of emerging epigenetic-targeting degraders.
