ObjectiveTo address the shortage of high-caliber multidisciplinary professionals in China's rehabilitation engineering field and the prominent issue of "separation between medicine and engineering" in existing curricula, this study introduces the World Health Organization rehabilitation competency framework (RCF) to construct a systematic curriculum system for rehabilitation engineering. MethodsGuided by the four core competency domains of RCF (practice, professionalism, learning and development, management and leadership) and their associated supporting knowledge, the rehabilitation engineering curriculum was restructured into a modular framework, piloted and validated within the Biomedical Engineering (Intelligent Robotics) program at University of Health and Rehabilitation Sciences. ResultsA four-tiered curriculum system comprising General Education-Disciplinary Platform-Professional Core-Diverse Electives with a total of 160 credits was established, achieving precise mapping between competency objectives and course content. The students in the pilot cohort demonstrated outstanding academic performance (50% ranked in the top ten of their major), they also gained a deeper understanding and mastery of interdisciplinary knowledge integrating medicine and engineering. ConclusionThe RCF-based curriculum system effectively promotes the organic integration of medical and engineering knowledge, providing an internationally aligned competency-oriented paradigm for rehabilitation engineering talent cultivation, which holds significant value for broader application.

As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

ObjectiveTo evaluate the therapeutic effect and mechanism of tendon-management and patella-movement therapeutic manipulation in the treatment of patellofemoral arthritis based on imaging evaluation. MethodsTotally 126 patients with patellofemoral arthritis were recruited and divided into a treatment group and a control group according to a randomised numerical table. The control group received routine sodium hyaluronate injection once a week for a total of 5 times； the treatment group received tendon-management and patella-movement therapeutic manipulation three times a week for four weeks. We compared the Western Ontario and McMaster University osteoarthritis index score （WOMAC）， visual analogue scale （VAS）， imaging indicators including patellar external displacement distance， patellofemoral fit angle， lateral patellofemoral angle， and patellofemoral index， and overall effectiveness evaluation between the two groups before and one week after treatment. ResultsThe total effective rate of the treatment group （45/54， 83.33%） was significantly higher than that of the control group （36/54， 66.67%，P＜0.05）. One week after the end of treatment， the VAS scores and WOMAC scores of both groups were lower than those before treatment in the same group （P＜0.01）， and the patellofemoral index and patellofemoral fit angle of the treatment group decreased compared with that of the control group （P＜0.05）. Compared with the pre-treatment， the distance of patellar external displacement， patellofemoral index， and patellofemoral fit angle decreased in the treatment group 1 week after the end of treatment， and the patellofemoral fit angle decreased in the control group （P＜0.05）. ConclusionThe therapeutic manipulation of tendon-management and patella-movement can correct the degree of patellar external displacement， alleviate joint pain symptoms， improve joint function， and achieve the goal of treating patellofemoral arthritis.

Objective: To investigate the efficacy and safety of intelligent temperature-pressure-controlled flexible ureteroscopy combined with negative-pressure suction sheath lithotripsy in the treatment of upper urinary tract stones ≤2.5 cm. Methods: The clinical data of 225 patients with ≤2.5 cm upper urinary tract stones treated with this surgical method in our department during Aug. 2023 and Jul. 2024 were retrospectively analyzed. The patients were divided into the dual-control group (n=36) and conventional group (n=189) according to whether or not the intelligent temperature and pressure control device was used during operation. In the dual-control group，the intraoperative temperature and pressure in the renal pelvis were monitored and controlled in real time by the temperature and pressure sensors distributed at the end of the ureteral soft lens. The perioperative parameters，stone-removal rate，complication rate and renal function were compared between the two groups. Results: All operations were successfully completed in both groups. The postoperative procalcitonin (PCT) level [(22.75±5.85) ng/L vs. (29.08±6.60) ng/L，P=0.001]，difference in the white blood cell (WBC) level [(0.24±2.12)×10 cells/L vs. (1.19±2.17)×10 cells/L，P=0.016]，incidence of fever (2.8% vs. 16.9%，P=0.028) and overall complication rate (5.6% vs. 19.6%，P=0.042) were significantly lower in the dual-control group than in the conventional group，while the stone-clearance rate was slightly higher (88.9% vs. 82.5%，P=0.346)，with no significant difference. Conclusion: For upper urinary tract stones ≤2.5 cm，intelligent temperature-pressure-controlled ureteroscopy combined with negative-pressure suction sheath lithotripsy has a satisfactory stone-removal rate and a low rate of complications，which is worthy of clinical promotion.

[Objective] To explore the strategy of blood management in patients with massive transfusion in the frigid plateau region. [Methods] The treatment process of a patient with liver rupture in the frigid plateau region was analyzed, and the blood management strategy of the frigid plateau region was discussed in combination with the difficulties of blood transfusion and literature review. [Results] The preoperative complete blood count (CBC) test results of the patient were as follows: RBC 3.14×10¹²/L, Hb 10⁶ g/L, HCT 30.40%, PLT 115.00×10⁹/L; coagulation function: PT 18.9 s, FiB 1.31 g/L, DD > 6 μg/mL, FDP 25.86 μg/mL; ultrasound examination and imaging manifestations suggested liver contusion and laceration / intraparenchymal hematoma, splenic contusion and laceration, and massive blood accumulation in the abdominal cavity; it was estimated that the patient's blood loss was ≥ 2 000 mL, and massive blood transfusion was required during the operation; red blood cell components were timely transfused during the operation, and the blood component transfusion was guided according to the patient's CBC and coagulation function test results, providing strong support and guarantee for the successful treatment of the patient. The patient recovered well after the operation, and the CBC test results were as follows: RBC 4.32×10¹²/L, Hb 144 g/L, HCT 39.50%, PLT 329.00×10⁹/L; coagulation function: APTT 29.3 s, PT 12.1 s, FiB 2.728 g/L, DD>6 μg/mL, FDP 25.86 μg/mL. The patient was discharged after 20 days, and regular follow-up reexamination showed no abnormal results. [Conclusion] Individualized blood management strategy should comprehensively consider the patient’s clinical symptoms, the degree of hemoglobin decline, dynamic coagulation test results and existing treatment conditions. Efficient and reasonable patient blood management strategies can effectively improve the clinical outcomes of massive transfusion patients in the frigid plateau region.

This article reviews the benifits and challenges of nano-microspheres (NPs) in the treatment of osteoarthritis (OA). OA is a degenerative disease associated with aging, trauma, and excessive loading, with treatment strategies including basic therapy, drug therapy, reparative therapy, and reconstructive surgery. As emerging nanomaterials, NPs offer unique advantages in promoting cartilage repair due to their high surface area, excellent drug-loading capacity, and good biocompatibility. These advantages include facilitating chondrocyte generation through magnetic-mechanical control of mesenchymal stem cell microspheres and enhancing antioxidant levels using biomimetic liposomal NPs combined with glucosamine. Additionally, NPs can effectively modulate inflammatory responses, such as by inhibiting the formation of M1 macrophages and promoting their polarization to the M2 type to alleviate inflammation. Some NPs also enhance joint lubrication and relieve pain, such as hyaluronic acid-based NPs modified with choline phosphate groups. However, the application of NPs faces challenges such as high production costs, poor biocompatibility for certain types, and unknown long-term safety. Despite these challenges, with advancements in nanotechnology and a deeper understanding of the pathological mechanisms of OA, NPs are expected to provide new therapeutic approaches and more comprehensive and effective treatment options for OA patients in the future.

Objective:To test the difficulty, discrimination, and reliability of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire.Methods:Two researchers independently translated the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire and cross-checked it to form a Chinese version of the questionnaire. The Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire consists of 24 items, with correct answers scoring one point and incorrect answers scoring zero points, with a total score of 24 points. Convenience sampling was used to select ICU nurses from 14 GradeⅢ Class A hospitals in five provinces/autonomous regions and two municipalities in China for the survey between April and July 2023. The difficulty index, discrimination index, and Cronbach's α coefficient of the questionnaire were analyzed.Results:A total of 1 121 questionnaires were distributed, with 1 020 valid responses, yielding a valid response rate of 90.99%. The mean score of the 1 020 ICU nurses on the Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire was (16.10±5.58) , with a minimum score of 4.00 and a maximum score of 24.00. The Cronbach's α coefficient of the Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire was 0.91. The questionnaire's overall difficulty and discrimination indexes were 0.67 and 0.59, respectively.Conclusions:The Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire has appropriate difficulty, moderate discrimination, and strong reliability, making it a valuable tool for assessing ICU nurses' knowledge of pressure injury-related topics.

Objective:To compare the clinical efficacy of laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy versus transperineal proctosigmoidectomy (Altemeier procedure) in the treatment of patients with complete rectal prolapse (CRP).Methods:This study employed a retrospective observational cohort design. Clinical data were collected from a total of 55 CRP patients who underwent surgical treatment between January 2018 and July 2023, including 25 patients from Luoyang Central Hospital, affiliated with Zhengzhou University, and 30 patients from the 989th Hospital of the Joint Logistics Support Force & Military Anorectal Surgery Research Institute. All patients undergoing surgery met the following criteria: aged ≥ 18 years, rectal prolapse protruding outside the anus, prolapse length > 5 cm with inability to self-reduce, conforming to the diagnostic criteria for CRP, and being first-time treated patients. Twenty-seven patients who underwent the Altemeier procedure between January 2018 and March 2021 were assigned to the Altemeier group; 28 patients who underwent laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy between April 2021 and July 2023 were assigned to the integral repair group. The therapeutic efficacy differences between the two groups were analyzed and compared, including the CRP length (DCRP), Wexner Constipation Score, Wexner Fecal Incontinence Score, and Gastrointestinal Quality of Life Index (GIQLI) before surgery and at 6, 12, and 24 months after surgery, as well as postoperative complications and recurrence at 24 months after surgery.Results:There were no statistically significant differences between the two groups in terms of gender distribution, age, preoperative body mass index (BMI), defecation frequency, DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI (all P>0.05). All patients completed the surgery. The length of hospital stay and intraoperative blood loss in the integral repair group were significantly less than those in the Altemeier group (both P<0.01). At 6, 12, and 24 months after surgery, the DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in both groups significantly improved compared with the preoperative values (all P<0.001). At 6, 12, and 24 months after surgery, the CRP treatment effect, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in the integral repair group were significantly better than those in the Altemeier group (χ2=15.821, P<0.001; χ2=18.238, P<0.001; χ2 = 12.558, P=0.001; and χ2 =22.413, P<0.001, respectively). In the integral repair group, 4 patients (14.3%) developed grade I-III postoperative complications, including 2 cases of urinary retention, 1 case of anastomotic bleeding, and 1 case of anastomotic stenosis. In the Altemeier group, 11 patients (40.7%) developed grade I-III postoperative complications, including 4 cases of urinary retention, 3 cases of anastomotic bleeding, 1 case of anastomotic stenosis, 2 cases of intestinal fistula, and 1 case of fecal incontinence. The difference between the two groups was statistically significant (χ2=4.850, P=0.028). There was no recurrence of CRP in the integral repair group at 24 months after surgery, while 7 cases of CRP recurrence were observed in the Altemeier group at 24 months after surgery. The difference between the two groups was statistically significant (χ2=6.148, P=0.013). Conclusion:The autologous fascia repair technique based on membrane anatomy and the pelvic floor integral theory is superior to the transperineal Altemeier procedure in the treatment of CRP. Furthermore, it is an effective surgical method for CRP.
