Objective To measure the urethral meatus circumference in middle-aged and elderly males to undergo surgery for benign prostatic hyperplasia (BPH), and to collect data for developing endoscopic equipment suitable for the male urethra in China. Methods Clinical data were collected from patients (aged ≥50 years) who underwent transurethral resection of prostate in the First Affiliated Hospital of Xi'an Jiaotong University during Jan. and Dec. 2024. All patients had the urethral meatus circumference measured with a metal urethral probe before surgery, followed by the use of a F26.5 endoscopic sheath for surgery. The passage of urethral meatus using different types of metal urethral probes were observed. Results For the 183 patients, the types of endoscopic sheath smoothly passing through the urethral meatus were distributed as follows:42 cases (22.95%) with F26 or above, 66 cases (36.07%) with F25-26, 27 cases (14.75%) with F23-24, 26 cases (14.21%) with F21-22, 22 cases (12.02%) with F20 or below, and the smallest was F17 (1 case). Of all patients, 59.02% (108/183) were able to insert the F26.5 endoscopic sheath smoothly into the urethral meatus (≥F25), 28.96% (53/183) required force or urethral dilation before inserting (F21-F24), and 12.02% (22/183) needed to open the urethral meatus before inserting the endoscopic sheath (≤F20). Conclusion When the most common F26.5 endoscopic sheath is used, 40.98% of the patients have the possibility of urethral injury, which is significantly too big for male transurethral surgery. For patients undergoing transurethral BPH surgery, a thinner sheath should be used to reduce the possibility of urethral injury and secondary iatrogenic urethral stricture.

Osteonecrosis of the mandible is also called avascular necrosis of the jaw, and it is a rare complication of bisphosphonates. It is characterized with pain, swelling, exposure of bone, local infection and pathologic fractures of the jaw. With the widespread usage of bisphosphonates in bone metastasis of malignant tumors and osteoporosis, this rare complication has received more attention in recent years. Here, we reported a case of bisphosphonates-related osteonecrosis of the jaw (BRONJ) caused by intravenous zoledronic acid for osteoporosis. A 62-year-old female patient with 7-year history of Sjögren's syndrome and 3-year history of osteoporosis developed BRONJ after 3-year treatment of zoledronic acid. Two months before she went to the Peking University International Hospital, she visited the dentist for periodontal purulent secretion and extracted one tooth from the right mandible. However, the condition was not improved and she felt persistent pain and swelling in the right mandible. Hence, she received repeated root curettage, but there was no improvement. Finally, she was diagnosed with osteonecrosis of the mandible based on the digital volume tomography scan, which showed right mandibular osteonecrosis bone destruction. She underwent surgical debridement of the necrotic bone and administered intravenous antibio-tics at the Peking University International Hospital. Histopathological analysis of the bone biopsy further confirmed the diagnosis of BRONJ. Her condition was improved successfully during a 3-year follow-up. Osteonecrosis of the mandible become more common with the increased use of bisphosphonates. Recent study has reported that osteonecrosis of the mandible is more likely to occur in patients with Sjögren's syndrome. In addition, age, long-term and irregular administration of glucocorticoids, irregular oral examination and treatment also might be the risk factors in the pathogenesis of osteonecrosis of the mandible. For the elder osteoporosis patients who would receive or had received bisphosphonate-related drugs, oral health status and the disease states associated with necrosis of the mandible such as Sjögren's syndrome should be comprehensively measured and fully evaluated during the whole process. Furthermore, to better understand and prevent or reduce the occurrence of this complication, we reviewed the patho-genesis, diagnosis, treatment, and prevention of BRONJ.

Objective: To evaluate the effect of exercise prescription intervention among patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for guiding appropriate physical activity and glycemic control in this population. Methods: In July 2023, T2DM patients managed by two community health service centers in Qingjiangpu District, Huai'an City, Jiangsu Province, were selected as the study participants and randomly assigned divided into a control group and an intervention group. The control group received routine chronic disease management under the basic public health services, while the intervention group, in addition to receiving the same routine chronic disease management, was provided with exercise prescription to guide their physical activity at baseline (T0), after 3 months of intervention (T1), and after 6 months of intervention (T2). Data on weight-related indicators, glycated hemoglobin (HbA1c), and blood lipid were collected through physical examinations and laboratory tests at T0 and after 12 months of intervention (T3). The differences in indicators between the two groups before and after the intervention were analyzed using generalized estimating equations. Results: The intervention group consisted of 197 patients, including 99 males, accounting for 50.25%. The median disease duration was 7.10 (interquartile range, 7.80) years, and 113 patients had suboptimal HbA1c levels, accounting for 57.36%. The control group included 196 patients, including 99 females, accounting for 50.51%. The median disease duration was 6.10 (interquartile range, 7.00) years, and 100 patients had suboptimal HbA1c levels, accounting for 51.02%. Before the intervention, no statistically significant differences were observed between the two groups in gender, educational level, disease duration, pharmacological treatment, smoking, alcohol consumption, and HbA1c levels (all P>0.05). In the intervention group, the proportion of participants engaging in aerobic exercise and strength training increased from 78.17% and 8.12% at T0 to 85.79% and 16.24% at T3, respectively (both P<0.05). The results of the generalized estimating equations revealed significant interactions between group and time for waist-to-hip ratio, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) following the intervention (all P<0.05). A statistically significant difference in waist-to-hip ratio was found between the two groups (P<0.05), with a greater reduction observed in the intervention group compared to the control group. Significant differences in TC and LDL-C levels were noted across different intervention time points (both P<0.05). Specifically, the intervention group demonstrated reductions of 0.35 mmol/L in TC and 0.42 mmol/L in LDL-C from baseline to follow-up (both P<0.05). Conclusion The 12-month exercise prescription intervention can effectively enhance exercise participation and reduce waist-to-hip ratio, TC, and LDL-C levels among patients with T2DM.

[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

Objective:To investigate the effect and potential mechanism of circular RNA-centrosome and spindle pole-associated protein 1 (circ-CSPP1) on the malignant biological behavior of hepatoma cells.Methods:Real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the expressions of circ-CSPP1 and microRNA-582-5p (miR-582-5p) in hepatoma cells, and Western blotting was used to detect the expression of karyopherins α2 (KPNA2). HepG2 cells were divided into the circ-CSPP1 overexpression group, the circ-CSPP1 overexpression control group, the si-CSPP1 group, the si-NC group, the si-CSPP1+ miR-582-5p inhibition group, and the si-CSPP1+ miR-582-5p inhibition control group. circ-CSPP1 overexpression plasmid, CSPP1 interfering small RNA, CSPP1 interfering small RNA, miR-582-5p inhibition sequence and negative control were transfected respectively in these groups. Cell proliferation in each group was detected by 5-acetylene-2'-deoxyuridine (Edu), invasion ability was detected by Transwell assay, and the binding of circ-CSPP1 and KPNA2 to miR-582-5p was verified by dual-luciferase assay. In the si-CSPP1 group, HepG2 cells transfected with si-CSPP1 lentivirus were subcutaneously injected into the back of nude mice ( n=12), and in the si-NC group, HepG2 cells transfected with negative control lentivirus ( n=12) were injected. The tumor mass, volume, circ-CSPP1 and KPNA2 were detected. Results:In the circ-CSPP1 overexpression group, the relative expression of circ-CSPP1 was (1.68±0.17), the expression of KPNA2 was (1.52±0.16), and the number of invasive cells in the 100-fold field of view was (128.4±13.5), which were all higher than those in the circ-CSPP1 overexpression control group [(1.25±0.16), (1.24±0.15), (128.4±13.5)], while the expression of miR-552-5p was lower than that in the circ-CSPP1 overexpression control group [(0.96±0.11) vs (1.31±0.15)]; The relative expression of circ-CSPP1 in the si-CSPP1 group was (1.02±0.13), KPNA2 was (0.74±0.09), and the number of invasive cells was (53.5±6.7), which were lower than those in the si-NC group [(1.28±0.14), (1.22±0.13), (74.6±8.3)], while the expression of miR-582-5p was higher than that in the si-NC group [(1.71±0.18) vs (1.32±0.14)]; The expression of circ-CSPP1 and KPNA2 and the number of invasion cells in the si-CSPP1+ miR-582-5p inhibition group was higher than that in the si-CSPP1+ miR-582-5p inhibition control group, and the differences were statistically significant (all P<0.05). The results of cell proliferation were consistent with those of invasion. The dual-luciferase gene report showed that, compared with the miR-NC group, the relative luciferase activity in HepG2 cells co-transfected with circ-CSPP1-WT or KPNA2-WT wild-type reporter vectors in the miR-882-5p mimic group decreased [(0.46±0.05) vs (1.03±0.11), (0.42±0.03) vs (1.01±0.09)]. The differences were all statistically significant (both P<0.05). However, there was no statistically significant difference in the relative luciferase activity in HepG2 cells co-transfected with the circ-CSPP1-MUT or KPNA2-MUT mutant reporter vectors (both P>0.05). The tumor weight, volume and circ-CSPP1 and KPNA2 expressions in tumor tissue of nude mice in the si-CSPP1 group were all lower than those in the si-NC group, and the expression of miR-582-5p was higher than that in the si-NC group. The differences were statistically significant (all P<0.05). Conclusion:Inhibition of circ-CSPP1 suppressed the malignant biological behavior of hepatoma cells and tumor growth by upregulating miR-582-5p and downregulating KPNA2.

Objective:To explore the application value of the "Dual-Wing" traction technique in the medial & head lateral laparoscopic left hemicolectomy with radical resection.Methods:The "Dual-Wing " traction technique is based on the theory of mesenteric anatomy. The assistant lifts the proper mesentery of the digestive tract to be resected or the adjacent mesenteric tissue connected to it,thereby elevating the target organ and its mesentery as a whole away from the mesenteric bed. By utilizing the tension transmission between the proper mesenteries of adjacent organs to create counter-tension,the surgeon's operative actions are always maintained along the line of maximum counter-tension.After incising the mesenteric fusion line,this technique assists the surgeon in entering the fusion plane. A descriptive case series study method was adopted to retrospectively analyze the clinical and pathological data of 37 colorectal cancer patients who underwent laparoscopic left hemicolectomy with the "Dual-Wing" traction technique via a medial and cephalad approach, performed by the Department of Gastrointestinal Surgery at Dongjie Campus of the First Hospital of Quanzhou, Fujian Medical University, from May 2023 to November 2023.Results:All patients successfully underwent laparoscopic left hemicolectomy via the medial & head lateral approach using the "Dual-Wing" traction technique.The surgery adhered to the principles of total mesocolic excision and safely mobilized the left colon and its mesentery from the correct anatomical plane. In the entire group of patients,there were 14 males and 23 females; the mean operative time was 94.1±18.3 minutes; the mean intraoperative blood loss was 9.8±5.4 ml; the mean number of lymph nodes dissected was 18.1±3.9; the mean number of positive lymph nodes was 1.4±1.6; the pathological specimen resection margin grading was Grade A in 29 cases, Grade B in 8 cases, and no Grade C cases; the tumor TNM staging was Stage I in 3 cases, Stage IIA in 7 cases, Stage IIB in 6 cases, Stage IIIA in 2 cases, Stage IIIB in 15 cases, and Stage IIIC in 4 cases; the mean time to first flatus postoperatively was 35.7±7.5 hours; the mean length of hospital stay was 9.1±1.7 days. There were no intraoperative injuries to the pancreas or spleen. Postoperative complications occurred in 3 cases. No anastomotic leakage was observed in the entire group, and there were no deaths following the surgery.Conclusion:The application of the "Dual-Wing" traction technique to establish a stable surgical scenario can significantly reduce the demands on the assistant. It is conducive to maintaining mesenteric tension and fully exposing the surgical field. It also allows for the rapid identification and maintenance of the correct anatomical plane. For colorectal cancer patients, the surgery is safe and feasible, with satisfactory short-term therapeutic effects.
