Aim To evaluate the ameliorative effects of different ratios of Renshen-Huangjing(RH) on SPS-induced PTSD-like behaviors in mice,and to investi-gate the action mechanism using bioinformatics analysis and experimental studies.Methods The aqueous ex-tract was extracted in four ratios of RH in a total weight of 60 g,i.e.1∶0(RH1),2∶1(RH2),1∶2(RH3),and 0∶1(RH4).The extraction rates of Rg1,Rb1,and polysaccharides from different ratios of RH were then detected using UPLC-UV method.The SPS model was established,and RH1,RH2,RH3 and RH4(400 mg·kg-1)were administered by intragas-tric gavage for 14 day,followed by behavioral tests to e-valuate the PTSD-like behaviors.The serum CORT,IL-1β and IL-10 were determined by ELISA.The possible targets of action were analyzed using bioinformatics.The expression levels of Calpain-1,PSD95,BDNF and GluN2B in the hippocampus were detected by Western blot.Results The SPS model induced PTSD-like be-haviors in mice.Serum levels of CORT and IL-1β in-creased and level of IL-10 decreased in SPS model.After treatment with different ratios of RHs,RH2 showed the best therapeutic effect,which was manifes-ted in the suppression of PTSD-like behaviors,the re-duction of CORT and IL-1β levels,and the promotion of IL-10 levels;160 overlapping targets might explain the therapeutic effects of RH on PTSD,and these tar-gets were enriched in inhibiting synaptic damage,exer-ting antioxidant properties and suppressing neuroin-flammation,respectively.RH2 prevented the SPS-in-duced decrease in the expression of Calpain-1,PSD95,BDNF and the elevation of GluN2B.Molecular docking showed strong binding of Rg1 and Rb1 to Calpain-1,PSD95,and BDNF,respectively.Conclusions The a-queous extract of RH in a 2∶1 ratio can more effec-tively prevent SPS-induced PTSD-like behaviors,and its effect may be related to targets such as Calpain-1,PSD95,BDNF and GluN2B.

Objective:To compare the safety and efficacy of novel en-bloc Holmium laser enucleation of the prostate（HoLEP）with complete membranous urethral mucosa sparing technique with traditional 2-lobe technique HoLEP in benign prostatic hyperplasia（BPH）treatment.Methods:The data of BPH patients treated with HoLEP from January 2023 to May 2024 in Xinhua Hospital，School of Medicine，Shanghai Jiaotong University were retrospectively reviewed. Seventy-two patients received novel en-bloc HoLEP with complete membranous urethral mucosa sparing technique（novel en-bloc group），while 79 patients received traditional 2-lobe technique HoLEP（traditional 2-lobe technique group）.There was no significant difference between novel en-bloc group and traditional 2-lobe technique group in the age［（71.0 ± 7.1）years vs.（69.8 ± 6.5）years］，body mass index［（24.5 ± 2.8）kg/m 2 vs.（23.9 ± 3.5）kg/m 2］，international prostate symptom score（IPSS）［26.0（22.0，28.0）vs. 25.0（22.0，28.0）］，quality of life（QOL）score［5.0（5.0，6.0）vs. 5.0（5.0，6.0）］，prostate sepcific antigen（PSA）［4.98（2.40，11.11）ng/ml vs. 4.38（1.62，7.54）ng/ml］and prostate volume［（74.06 ± 42.67）ml vs.（70.10 ± 33.94）ml］（all P > 0.05）. The incidence of acute urinary retention in novel en-bloc group was significantly higher than that in traditional 2-lobe technique group［31.94%（23/72）vs. 17.72%（14/79）， P = 0.042］.The procedure of novel en-bloc was shown as followed：expose the prostatic capsule near the verumontanum and expand the initial capsule plane on both sides. The prostatic urethral mucosa was cut off in a circular pattern medial to the external urethral sphincter，which could form a complete “circular mucosal pad”. Seperate the apical gland along the capsule plane at 12 o’clock and expand the capsule plane until the bladder neck was reached.The bladder neck was then used as a marker so as to separate the glands on both sides along the capsule plane and merge with the initial plane. The entire lobe of the prostate was finally removed along the surgical capsule of the prostate. The procedure of traditional two lobe method was shown as followed：expose the prostatic capsule near the verumontanum and then divide the prostate into two lobes by longitudinal incision at 6 and 12 o’clock. The mucosa was horizontally cut at 12 o’clock，medial to the external urethral sphincter in order to preserve the apical urethral mucosal flap. The twp lobes were then removedd respectively along the capsule layer. The surgery-related indicators，perioperative complications and other data were compared between the two groups，as well as IPSS，QOL score，lower urinary tract symptoms，and the incidence of stress urinary incontinence in the two groups 1 month after surgery. Results:Compared with the patients underwent 2-lobe technique HoLEP，the patients underwent novel en-bloc HoLEP had lower hemoglobin loss［0.50（-5.50，7.50）g/L vs. 7.00（1.00，13.25）g/L， P = 0.003］，lower operation time［（72.06 ± 34.37）min vs.（85.42 ± 40.35）min， P = 0.030］，higher surgical efficacy［（0.72 ± 0.31）g/min vs.（0.55 ± 0.29）g/min， P = 0.002］and lower incidence of stress urinary incontinence one month after operation［2.78%（2/72）vs. 10.13%（8/79）， P = 0.070］. There was no significant difference in the incidence of postoperative gross hematuria［0 vs. 2.53%（2/79）］，postoperative sepsis［1.39%（1/72）vs. 1.27%（1/79）］，postoperative dysuria［4.17%（3/72）vs. 5.06%（4/79）］，postoperative IPSS improvement［12.0（11.0，13.0）vs. 12.0（10.0，14.0）］and postoperative QOL improvement［3.0（2.0，3.0）vs. 3.0（2.0，3.0）］between the two groups（ P > 0.05）. The patients were further divided into 2 sub-groups according to whether prostate volume ≥ 60 ml or not. In the patients of prostate volume < 60 ml，surgical efficacy was significantly higher in novel en-bloc HoLEP group than that in traditional 2-lobe technique group［（0.55 ± 0.25）g/min vs.（0.41 ± 0.19）g/min， P = 0.028］. In the patients of prostate volume ≥ 60 ml，the surgical efficacy of novel en-bloc HoLEP was also higher［（0.88 ± 0.28）g/min vs.（0.66 ± 0.31）g/min， P = 0.006］. Conclusions:Novel en-bloc HoLEP with complete membranous urethral mucosa sparing technique was demonstrated to has lower blood loss，shorter operation time，higher surgical efficacy and lower incidence of stress urinary incontinence，which is suitable of all sizes of prostate.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To explore the clinical application of transurethral steam thermal ablation of the prostate as an ultra-minimally invasive treatment of benign prostatic hyperplasia(BPH).Methods:We treated 18 BPH patients by transurethral steam thermal ablation of the prostate in our hospital,and followed them up for 6-12 months after operation.We obtained the IPSS,maxi-mum urinary flow rate(Qmax),IIEF-5 scores,Male Sexual Health Questionnaire-Ejaculatory Dysfunction-Short Form(MSHQ-EjD-SF)scores and quality of life(QOL)scores from the patients and compared them before and after surgery.Results:Operations were successfully completed in all the cases,with no intraoperative complications,and all the patients were discharged on the second day after surgery.At the 6-month follow-up after surgery,the Qmax increased from(10.08±2.06)ml/s before surgery to(7.51±3.21)ml/s,the IPSS decreased from 23.72±1.87to8.06±1.39,and the QOL score decreased from 5.11±0.58 before sur-gery to 1.28±0.46.The differences in these indicators were statistically significant(P＜0.05).And these is no significant differ-ence in the MSHQ-EjD-SF and IIEF-5 score(P＞0.05).Conclusion:Transurethral steam thermal ablation of the prostate is a safe,effective and almost non-invasive surgical strategy for the treatment of BPH,with a good prospect of clinical application.
