OBJECTIVES: To compare the anti-inflammatory, antibacterial and analgesic effects of Yinqiao Powder (YQS) formulated granules and decoction. METHODS: We first evaluated the anti-inflammatory effects of the two dosage forms of YQS in a LPS-induced RAW 264.7 cell model using RT-qPCR and Western blotting. We further constructed zebrafish models of inflammation by copper sulfate exposure, caudal fin transection, or LPS and Poly (I:C) microinjection, and evaluated anti-inflammatory effects of YQS granules and decoction by examining neutrophil aggregation and HE staining findings. In a mouse model of acute lung injury (ALI) induced by intratracheal LPS instillation, the effects of YQS gavage at 10, 15, and 20 g/kg on lung pathologies were evaluated by calculating lung wet-dry weight ratio and using HE staining, ELISA and Western blotting. The microbroth dilution method was used to evaluate the antibacterial effect of YQS. Mouse pain models established by hot plate and intraperitoneal injection of glacial acetic acid were used to evaluate the analgesic effects of YQS at 10, 15, and 20 g/kg. RESULTS: Both YQS granules and decoction significantly reduced TNF-α, IL-6, and IL-1β expressions and p-STAT3 (Tyr 705) phosphorylation level in LPS-induced RAW 264.7 cells, and obviously inhibited neutrophil aggregation in the zebrafish models. In ALI mice, YQS granules and decoction effectively ameliorated lung injury, lowered lung wet-dry weight ratio, and reduced p-STAT3 (Tyr 705) expression and TNF-α and IL-6 levels. YQS produced obvious antibacterial effect at the doses of 15.63 and 31.25 mg/mL, and significantly reduced body torsion and increased pain threshold in the mouse pain models. CONCLUSIONS The two dosage forms of TQS have similar anti-inflammatory, antibacterial and analgesic effects with only differences in their inhibitory effect on TNF-α, IL-6 and IL-1β mRNA expressions in LPS-induced RAW 264.7 cells.

Objective:To explore the short-term oncological efficacy of the total prostatic urethra preservation（TPUP）technique in laparoscopic radical prostatectomy and its impact on postoperative urinary continence rate.Methods:The clinical data of 17 prostate cancer patients admitted to Shaoxing People’s Hospital from July 2023 to July 2024 were retrospectively analyzed. The age was（70.5 ± 6.5）years，the body mass index was（23.6 ± 2.5）kg/m 2，and the prostate-specific antigen（PSA）level was（7.845 ± 3.929）ng/ml. The preoperative biopsy pathological Gleason score were 6 in 8 cases，and 7 in 9 cases. All patients underwent laparoscopic radical prostatectomy，and the TPUP technique was used during the operation. The integrity of the preserved urethra was improved by preserving the prostatic surgical capsule closely attached to the corpus spongiosum of the urethra. During the operation，the urethra was completely preserved in 2 cases，nearly completely preserved in 14 cases，and partially preserved in 1 case. The recovery of urinary continence on the day of catheter removal and at 1 and 3 months after the operation was recorded. Recovery of urinary continence was defined as pad within 24 hours. PSA was re - examined at 6 weeks and 3 months after the operation. Results:All 17 operations in this study were successfully completed. The operation time was（143.6 ± 31.6）minutes，and the intraoperative blood loss was 50.0（20.0，50.0）ml. None of the cases was converted to open surgery，and no Clavien - Dindo grade ≥ 2 complications such as blood transfusion or intestinal injury occurred during the peri-operative period. The PSA levels at 6 weeks and 3 months after the operation were 0.054（0.008，0.215）ng/ml and 0.008（0.005，0.037）ng/ml，respectively. The indwelling catheter time after the operation was（13.4 ± 2.1）days. The number of cases with recovered urinary continence on the day of catheter removal and at 1 and 3 months after the operation was 10，15，and 17，respectively.Conclusions:The TPUP technique in laparoscopic radical prostatectomy leads to good recovery of postoperative urinary continence，and there is a slowly PSA decrease in the short term.

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.

Objective:To investigate the efficacy and safety of linaclotide(LIN) combined with polyethylene glycol(PEG) for bowel preparation in patients with functional constipation (FC).Methods:From August 1, 2022 to April 30, 2023, a total of 300 patients with FC (FC group) and 300 subjects with non-functional constipation (NFC, NFC group) undergoing colonoscopy at the Affiliated Hospital of Qingdao University were selected. According to simple random sampling method, both FC group and NFC group were divided into 3 L PEG subgroup, 3 L PEG+ LIN subgroup, and 2 L PEG+ LIN subgroup, respectively, with 100 cases in each group and a total of 6 subgroups. All subjects were enrolled based on a random number table and received the corresponding bowel preparation protocols. The Ottawa bowel preparation score (OBPS) and the rate of adequate bowel preparation were calculated. Ordered logistic regression analysis was used to analyze the independent influencing factors of OBPS. The incidence of adverse events (such as bloating) and the repetition rate of regimen intention were analyzed. One-way ANOVA, least significant difference analysis, and chi-square test were used for statistical analysis.Results:The OBPS of the 3 L PEG subgroup, 3 L PEG+ LIN subgroup, and 2 L PEG+ LIN subgroup in the FC group were 6.06±1.67, 3.86±2.20, and 4.06±2.03, respectively, while the OBPS of the 3 corresponding subgroups in the NFC group were 5.08±1.92, 3.42±2.04, and 3.63±1.93, respectively. The OBPS scores of the 2 L PEG+ LIN and 3 L PEG+ LIN subgroups in FC and NFC group were lower than those of the 3 L PEG subgroup within the respective group, and the differences were statistically significant ( t=7.16, 7.55, 4.59, and 6.06; all P<0.001). The rates of adequate bowel preparation of the 3 L PEG subgroup, 3 L PEG+ LIN subgroup, and 2 L PEG+ LIN subgroup in the FC group were 83.0% (78/94), 95.6% (87/91), and 96.8% (92/95), respectively, while the rates of adequate bowel preparation of the 3 subgroups in the NFC group were 88.0% (88/100), 96.9%(94/97), and 97.0%(96/99), respectively. The rates of adequate bowel preparation of 2 L PEG+ LIN and 3 L PEG+ LIN subgroups in FC and NFC group were higher than those of the 3 L PEG subgroup in the respective group, and the differences were statistically significant( χ2=10.04, 7.64, 5.74, and 5.55, P=0.001, 0.008, 0.029, 0.029). The FC group was divided into 2 L PEG+ LIN compared to 3 L PEG+ LIN subgroup, as well as 3 L PEG+ LIN compared to 3 L PEG subgroup for ordinal logistic regression analysis, and the result showed that the bowel preparation regimen was an independent influencing factor for OBPS ( OR=0.940 and 3.072, 95% confidence interval 0.368 to 1.483 and 1.564 to 3.252; both P<0.001). The incidence of abdominal distension of the 3 L PEG subgroup in FC group and NFC group was higher than that of the 2 L PEG+ LIN subgroup in the respective group (11.7%(11/94) vs. 3.2%(3/95), 12.0%(12/100) vs. 4.0%(4/99)), and the differences were statistically significant( χ2=5.03 and 4.26, P=0.028 and 0.045). The repetition rates of regimen intention of the 2 L PEG+ LIN and 3 L PEG+ LIN subgroups in FC and NFC groups were higher than that of the 3 L PEG subgroup in respective group (93.7%(89/95), 93.4%(85/91) vs. 80.9%(76/94); 92.9%(92/99), 92.8%(90/97) vs. 82.0%(82/100)), and the differences were statistically significant ( χ2=5.25, 8.70, 4.31, and 5.40; P=0.009, 0.015, 0.020, and 0.023). Conclusions:The 2 L PEG+ LIN regimen can effectively decrease OBPS, improve qualified rate of bowel preparation and repetition rate of regimen intention, and reduce adverse events and the amount of fluid intake, in order to improve the tolerance and compliance of patients. Therefore, the 2 L PEG+ LIN regimen is recommended as a bowel preparation for colonoscopy in patients with FC.
