Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

BACKGROUND:
Endoscopic sphincterotomy (EST) is widely used to treat common bile duct stones (CBDS); however, long-term studies have revealed the increasing incidence of recurrent CBDS after EST. Loss of sphincter of Oddi function after EST was the main cause of recurrent CBDS. Reparation of the sphincter of Oddi is therefore crucial. This study aims to investigate the effectiveness and safety of endoclip papilloplasty (ECPP) for repairing the sphincter of Oddi and elucidate its mechanism.
METHODS:
Eight healthy Bama minipigs were randomly divided into the EST group and the ECPP group at a 1:1 ratio, and bile samples were collected before endoscopy and 6 months later. All minipigs underwent transabdominal biliary ultrasonography for the diagnosis of cholelithiasis 6 months after endoscopy. The biliary microbiota composition and alpha and beta diversity were analyzed by 16S ribosomal RNA gene sequencing. Differential metabolites were analyzed by bile acid metabolomics to explore the predictive indicators of cholelithiasis.
RESULTS:
Three minipigs were diagnosed with cholelithiasis in the EST group, while none in the ECPP group showed cholelithiasis. The biliary Firmicutes/Bacteroidota (F/B) ratio was increased after EST and decreased after ECPP. The Chao1 and observed species index significantly decreased 6 months after EST ( P = 0.017 and 0.018, respectively); however, the biliary α-diversity was similar before and 6 months after ECPP. The β-diversity significantly differed in the EST group before and 6 months after EST, as well as in the ECPP group before and 6 months after ECPP (analysis of similarities [ANOSIM]: R = 0.917, P = 0.040; R = 0.740, P = 0.035; respectively). Glycolithocholic acid (GLCA) and taurolithocholic acid (TLCA) accumulated in bile 6 months after EST.
CONCLUSIONS
ECPP has less impact on the biliary microenvironment than EST and prevents duodenobiliary reflux by repairing the sphincter of Oddi. The bile levels of GLCA and TLCA may be used to predict the risk of cholelithiasis.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

Objective To analyze the mechanism that Hcp1 protein in type Ⅵ secretion system of Burkholderia pseudomallei(B.pseudomallei)mediates the formation of multinucleated giant cells(MNGCs)when host cells are infected by the bacterium.Methods The mutant strain(BPC006 Δhcp1)and complementation strain(BPC006 Δhcp1::hcp1)were constructed by homologous recombination and plasmid complement technology,respectively.After RAW264.7 cells were infected with B.pseudomallei,the localization of Hcp1 in host cells was analyzed by immunofluorescence staining.The localization was further verified by cytoplasmic-membrane isolation in 293T cells after transfecting pCDNA4.1-Hcp1.The biological significance and effect of Hcp1 were explored by the anti-Hcp1 polyclonal antibody blocking and the formation of MNGC was detected by Giemsa staining.Results Western blotting showed that BPC006 Δhcp1 could not express Hcp1,while BPC006 Δhcp1::hcp1 restored Hcp1 expression.The above results proved that the mutant and complement strains were successfully constructed.Both cellular immunofluorescence co-localization and cytoplasmic-membrane isolation experiments showed that Hcp1 localized to host cell membranes.Last but not least,compared with the control group,anti-Hcp1 polyclonal antibodies inhibited the formation of MNGC(P<0.01).Conclusion Hcp1 protein in type Ⅵ secretion system of B.pseudomallei is able to translocate to the RAW264.7 cell membranes and plays an important role in the formation of MNGCs.

Objective:To evaluate the effectiveness and safety of mesenchymal stem cells (MSCs) in the treatment of knee osteoarthritis (KOA).Methods:The databases PubMed, OVID, Web of Science, CNKI, Wanfang, were systematically searched from inception to May 2023 to collect randomized control trials(RCTs) of MSCs in the treatment of KOA. The literature was selected according to the inclusion and exclusion criteria, and relevant data was extracted. Meta-analysis was conducted using RevMan 5.4 software. Heterogeneity was assessed using the I2 statistic, with the fixed effects model applied when I2 was less than 50%, and the random effects model utilized otherwise. The combined effect size and 95% confidence interval ( CI) were calculated using the inverse-variance method. Sensitivity analysis and assessment of publication bias were performed using Stata 14.0 software. Results:A total of 29 RCTs involving 1 402 participants were included. The outcomes showed that at the 12 month follow-up, MSCs reduced pain [WOMAC pain: MD(95% CI)=-4.38(-7.22, -1.55), P<0.001; VAS: MD(95% CI)=-2.00(-2.67, -1.33), P<0.001 ]. And WOMAC stiffness[WOMAC stiffness:MD(95% CI)=-1.21(-2.32, -0.10), P<0.001]; moreover, MSCs reduced KOA severity and Restored joint function, [WOMAC: MD(95% CI)=-9.40(-15.87,-2.93), P<0.001; Lequesne: MD(95% CI)=-10.57(-15.89, -5.24), P<0.001 ].And the effect lasted for at least 4 years. MRI analysis showed no significant difference between the MSC group and the control group [MD(95% CI)=-6.68 (-18.45, 5.09), P=0.270]. Subgroup analysis showed that there was no significant difference in the effects of the tissue source and dosage of MSC on osteoarthritis pain and joint function. Using WOMRS for subgroup analysis, we found that adipose tissue was the best MSCs source for cartilage repair in osteoarthritis [MD (95% CI) =-30.94(-43.87, -18.01), P<0.001]. For the occurrence of adverse events, no study had reported the occurrence of serious adverse events. Most of the adverse events were self-limited pain and discomfort, such as transient joint swelling and back pain. Conclusion:Based on current evidence, MSCs may be a safety therapy that have a good effect for OA, and the time to maintain the curative effect is no less than 4 years. There is currently no reliable evidence to address the issue of which tissue source and injection cell dosage yield the best therapeutic effect. High-quality clinical trials are needed.

Objective:To investigate the effect of total anatomical reconstruction (TAR) during robot-assisted radical prostatectomy (RARP) .Methods:The clinical data of 99 patients with RARP performed by a single doctor in our hospital from January 2018 to January 2021 were analyzed retrospectively.There were 38 patients in the TAR+ vesicourethral anastomosis (VUA) group and 61 patients in the VUA group. There were no significant differences between the two groups in the age of patients [ 65.5 (60.8, 71.0) years vs. 66.0 (61.5, 69.0) years], body mass index[ (24.92±2.65) kg/m 2 vs. (25.51±2.80) kg/m 2], prostate volume [28.13 (25.21, 36.53) ml vs. 26.33 (19.75, 47.84) ml], PSA [15.67 (9.02, 31.49) ng/ml vs. 14.58 (9.23, 30.06) ng/ml], neoadjuvant therapy [50.0% (19/38) vs. 63.9% (39/61)], Gleason score (6/7/8/9-10 scores: 8/16/5/9 cases vs. 16/25/9/11 cases) and clinical T stage (T 1/T 2/T 3 stage: 4/29/5 cases vs. 3/53/5 cases)(all P>0.05). The TAR technique was performed as follows. ①The two layers of posterior reconstruction involved the residual Denonvilliers fascia, the striated sphincter and medial dorsal raphe (MDR), and the vesicoprostatic muscle (VPM), the fascia which was 1-2 cm from the cranial side of the bladder neck and MDR. ②The one layer of anterior reconstruction involved detrusor apron, tissues around the urethra and the visceral and parietal layers of the endoplevic fascia. The VUA technique was suturing the bladder neck and urethra consecutively. Perioperative indexes were compared between the two groups. Results:All 99 operations were successfully completed. There were no statistically significant differences between the TAR+ VUA and VUA groups in operation time [ (174.16±47.21) min vs. (188.70±45.39) min], blood loss [ 50 (50, 100) ml vs. 100 (50, 100) ml], incidence of postoperative complications [10.5% (4/38) vs. 14.8% (9/61)], phathological T stage [pT 2/pT 3~4 stage: 25/12 cases vs. 42/19 cases, P=0.895], and the time of indwelling catheter [ 21.0 (19.0, 21.0) d vs. 21.0 (21.0, 21.0) d] (all P>0.05). The difference in postoperative length of stay between the two groups was statistically significant[6.0 (5.0, 6.0) d vs. 7.0 (6.0, 7.5)d, P<0.001]. Follow-up was performed for 1 year after surgery. The recovery rate of urinary continence 3 months after surgery in TAR+ VUA and VUA groups were 86.8% (33/38) vs. 65.6% (40/61), which were statistically significant( P=0.019). There were no significant differences between TAR+ VUA and VUA groups in recovery rate of urinary continence 1 months after surgery [47.4% (18/38) vs. 45.9% (28/61)], 6 months after surgery [94.7% (36/38) vs. 85.2% (52/61)], and 12 months after surgery [94.7% (36/38) vs. 93.4% (57/61)] (all P>0.05). Conclusions:TAR technique has good surgical safety, and can promote recovery of early urinary continence after RARP.

Objective:To compare the changes of biliary microbiota after enteral extended biliary stents (EEBS) implantation with that of conventional plastic stents in animal experiment, and to preliminarily investigate its possible mechanism in preventing stents occlusion.Methods:A total of 12 healthy Bama minipigs were randomly assigned to the conventional plastic stent group ( n=6) and the EEBS group ( n=6) using simple random method. The bile samples of all pigs were collected before stents implantation and 4 weeks after stents placement. The biliary microbiota composition and diversity before and after different stents implantation were analyzed by 16S rRNA gene sequencing and compared. Results:No complications including acute cholangitis, perforation, bleeding, or death occurred in 12 pigs. Eight days after stents implantation, stents were out of bile duct in all pigs under endoscopy, while the bile samples were collected again for analysis. The main composition of biliary microbiota at the phylum level were Proteobacteria, Firmicutes and Bacteroidota. Alpha-diversities revealed the Shannon ( P=0.004) and Simpson index ( P=0.008) significantly decreased in the conventional stent group after stents placement, and Bata diversity analysis also showed a significant difference in microbial composition (Anosim: R=0.514 8, P=0.011). There was no significant difference in Observed species index ( P=0.095), Chao1 index ( P=0.136), Shannon index ( P=0.353), Simpson index ( P=0.227) or Bata diversity (Anosim: R=0.059 3, P=0.187) in the EEBS group before and after stents placement. LEfSe algorithm indicated Bacteroides_ fragilis and Proteobacteria- Gammaproteobacteria- Enterobacterales- Enterobacteriaceae- scherichia_ Shigella- Escherichia_ coli significantly increased in the conventional stent group, and Desulfobacterota- Desulfovibrionia- Desulfovibrionales- Desulfovibrionaceae- Bilophila significantly increased in the EEBS group after stents placement. Conclusion:The biliary microbiota change slightly after EEBS implantation in the short-term, and EEBS may prevent duodenobiliary reflux by prolonging the reflux path.
