Based on serum metabolomics and gut microbiota technology, this study explores the effects and mechanisms of the water extract of Ziziphi Spinosae Semen(SZRW) and the petroleum ether extract of Ziziphi Spinosae Semen(SZRO) in improving depressive-like behaviors induced by sleep deprivation. A modified multi-platform water environment method was employed to establish a rat model of sleep deprivation. Depressive-like behaviors in rats were assessed through the sucrose preference test and forced swim test. The expression of barrier proteins, such as Occludin, in the colon was determined by immunofluorescence. UPLC-Q-Orbitrap MS was utilized to analyze the serum metabolic profiles of sleep-deprived rats, screen for differential metabolites, and analyze metabolic pathways. The diversity of the gut microbiota was detected using 16S rRNA gene sequencing. Spearman correlation coefficient analysis was conducted to assess the correlation between differential metabolites and gut microbiota. The results indicated that SZRO significantly increased the sucrose preference index and decreased the immobility time in the forced swim test in rats. A total of 34 differential metabolites were identified through serum metabolomics. SZRW and SZRO shared five metabolic pathways, including phenylalanine metabolism. SZRW uniquely featured taurine and hypotaurine metabolism, while SZRO uniquely featured linoleic acid metabolism and tyrosine metabolism. Correlation analysis revealed that SZRW could upregulate the abundance of Bilophila, promoting the production of indole-3-propionic acid and subsequently upregulating the expression levels of intestinal tight junction proteins such as ZO-1, Occludin, and Claudin-1. SZRO could indirectly influence metabolic pathways such as arginine metabolism and linoleic acid metabolism by upregulating the abundance of gut microbiota such as Coprococcus and Eubacterium species. Both SZRW and SZRO can regulate endogenous metabolism, including amino acids, energy, and lipids, alter the gut microbiota microecology, and improve depressive-like behaviors. SZRO demonstrated superior effects in regulating metabolic pathways and gut microbiota structure compared to SZRW. The findings of this study provide a scientific basis for elucidating the pharmacodynamic material basis of Ziziphi Spinosae Semen.

Objective:To investigate the efficacy and safety of percutaneous trans-hepatic choledochoscopic lithotripsy (PTCSL) in the treatment of recurrent hepatobiliary calculi under enhanced recovery after surgery (ERAS) mode.Methods:Clinical data of 88 patients with recurrent hepatobiliary calculi, who were treated with PTCSL at Zhengzhou Central Hospital Affiliated to Zhengzhou University and the First Affiliated Hospital of Xi'an Jiaotong University between June 2022 and June 2024 were retrospectively analyzed, including 34 males and 54 females, aged (52.0±13.8) years. The scheme includes preoperative education, prophylactic antibiotic application, ensuring the quality of surgery, early postoperative feeding and activity, etc. The operation can be divided into two fashions: percutaneous transhepatic cholangial drainage and PTCSL, which can be completed in one stage (one-stage expansion method) or in two stages (staged expansion method). Clinical data such as gender, age, operative time, intraoperative blood loss, residual stone, and surgical complications were recorded.Results:All 88 patients underwent PTCSL under ERAS mode successfully, including 52 cases using one-stage expansion method and 36 cases using staged expansion method. The operative time was (53±20) min, the intraoperative blood loss was (9.7±3.8) ml, the postoperative hospital stay was (3.6±1.7) d, and the hospitalization cost was (17 500±4 700) yuan. Sixty-nine patients (78.4%, 69/88) had one-time stone removal in the first PTCSL. A total of 19 cases of residual stones were managed again by percutaneous sinus soft choledochoscopy, of which 12 cases were managed by one-time choledochoscopy, five cases by two-time choledochoscopy, and two cases by three-time choledochoscopy. The rate of residual stone was significantly higher in one-stage expansion method compared to staged expansion method [28.8% (15/52) vs. 11.1% (4/36), P=0.040]. No death, conversion to open surgery, or severe complications such as intra-abdominal hemorrhage or bile leakage occurred in the patients. No residual stones or recurrence were found during the follow-ups of (7.5±2.1) months after discharge. Conclusion:PTCSL under ERAS mode is safe and effective in the treatment of recurrent hepatobiliary calculi.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objectives:To explore whether short-course radiotherapy (SCRT)-based total neoadjuvant therapy (TNT) combined with PD-1 inhibitors could further promote tumor regression and improve the prognosis.Methods:This is a prospective, multicenter, two-arm randomized controlled, seamless phase Ⅱ/Ⅲ trial for proficient mismatch repair or microsatellite stable (pMMR/MSS) locally advanced rectal cancer (LARC). Eligible patients were randomly assigned to the iTNT (TNT+PD-1) group or the TNT group. Patients in the TNT group received SCRT (5 Gy×5) followed by 4 cycles of CAPOX or 6 cycles of mFOLFOX chemotherapy, with the iTNT group receiving SCRT followed by the same regime in combination with 4 cycles of Sintilimab. Total mesorectal excision (TME) surgery or watch and wait (W&W) was performed after neoadjuvant therapy and then 2 cycles of same regimen as before were recommended. The primary endpoints are the complete response (CR) rate for phase Ⅱ trial and 3-year disease-free survival (DFS) for phase Ⅲ trial. A total of 588 patients will be enrolled for the phase Ⅱ/Ⅲ trial. Short-term efficacy and safety data from the initial 100 treated patients were analyzed as planned.Results:From 2022-8-31 to 2023-5-24 the initial 100 patients were enrolled from 10 hospitals in China, 76.0%(76/100) patients were male, and the median age was 61 years (21-74 years). More patients had tumors located in the lower rectum (78.0%, 78/100), staged T3-4 (97.0%, 97/100) and N1-2 (93.0%, 93/100), and about half of the tumors invaded the mesorectal fascia (52.0%, 52/100) and with extramural vascular invasion (51.0%, 51/100). Analyses were performed according to the per-protocal (PP) set. All patients in the iTNT group ( n=52) and the TNT group ( n=48) completed SCRT; The 4-cycle chemotherapy±Sintilimab completion rates were 86.5% and 100.0% in the iTNT and TNT groups, respectively. In the iTNT group, 82.7% (43/52), 11.5% (6/52), and 5.8% (3/52) of the patients received 4, 3, and 2 cycles of PD-1 inhibitor. After TNT, 68 patients underwent radical surgery and 15 patients achieved cCR and adopted W&W. The pathological complete response (pCR) rates were 48.5% (16/33) and 17.1% (6/35) in the iTNT and TNT groups, with CR rates of 50.0% (25/50) and 26.1% (12/46), respectively. The incidence of treatment-related grade 3-4 adverse events was 26.9% (14/52, iTNT group) and 18.8% (9/48, TNT group), with thrombocytopenia and leukopenia being the most common. Among patients receiving immunotherapy, grade 3 immunotherapy-related adverse events occurred in 2 (3.8%, 2/52) patients: one case was pancreatitis, another case was hepatitis combined with myositis and myocarditis. Conclusion:The preliminary results show that SCRT-based TNT combined with PD-1 inhibitors could further improve the CR rate for LARC without unexpected serious adverse events.

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 investigate the effect of FOXQ1 expression on chemoresistance in colorectal cancer and analyze its regulatory role in SIRT1 expression and p53 deacetylation under DNA damage response(DDR)condi-tions.Methods:qRT-PCR was used to detect FOXQ1 mRNA expression levels in SW620 cells and SW620 cells stimulated with cisplatin(CDDP).Lentiviral vectors were constructed for FOXQ1 overexpression and RNA interference.The cells were divided into three groups:FOXQ1 overexpression group(oe-FOXQ1),FOXQ1 RNA interference group(sh-FOXQ1),and a control group transfected with an empty vector(NC).The half-maximal inhibitory concentration(IC50)of CDDP in each group was determined using the CCK-8 assay.Apoptosis level and cell viability were assessed using the Annexin V-APC/7-ADD apoptosis detection kit and Calcein/PI staining.Western blot analysis was performed to evaluate the effect of FOXQ1 on SIRT1 expression and acetylated p53 levels.The SIRT1 pathway inhibitor(S)-Selisi-stat was introduced to observe changes in p53 acetylation levels.Results:Compared to normal colon tissues,FOXQ1 expression was significantly upregulated in SW620 cells(P＜0.05),and low-dose CDDP stimulation further en-hanced its expression(P＜0.05).After 24 hours of CDDP treatment,the IC50 values for the oe-FOXQ1,sh-FOXQ1,and NC groups were 58.3 μmol/L,36.4 μmol/L,and 43.7 μmol/L,respectively,with statistically significant differences among the groups(P＜0.05).Compared to the NC group,the oe-FOXQ1 group showed a decrease in late apoptotic cell count(P＜0.05),while the sh-FOXQ1 group exhibited an increase(P＜0.05).Cytotoxic fluorescence staining re-vealed that the proportion of cell death was lower in the oe-FOXQ1 group and higher in the sh-FOXQ1 group com-pared to the NC group(P＜0.05).Protein expression analysis showed that FOXQ1 and SIRT1 levels were higher in the oe-FOXQ1 group and lower in the sh-FOXQ1 group compared to the NC group(P＜0.05).FOXQ1 overexpression pro-moted p53 deacetylation,while the addition of the SIRT1 pathway inhibitor(S)-Selisistat restored p53 acetylation levels(P＜0.05).Conclusion:FOXQ1 promotes p53 deacetylation by upregulating SIRT1 expression,thereby inhibiting DDR-induced apoptosis.
