Patients with Takayasu arteritis combined with aortic valve disease often have a poor prognosis following surgical valve replacement, frequently encountering complications such as perivalvular leakage, valve detachment, and anastomotic aneurysm. This article presents a high-risk case wherein severe aortic valve insufficiency associated with Takayasu arteritis was successfully managed through transcatheter aortic valve implantation via the transapical approach. The patient had satisfactory valve function with no complications observed during the six-month postoperative follow-up. This case provides a minimally invasive and feasible alternative for the clinical management of such high-risk patients.

The international dissemination of Chinese acupuncture represents a successful model of medical and cultural exchange between the East and the West, as well as an exemplary case of Chinese culture going global. In 1971, following the announcement by Xinhua News Agency that "acupuncture anesthesia technology had achieved success", American medical educator Professor Edmunds Grey Dimond became the first foreign doctor to visit China for an investigation of acupuncture anesthesia. His efforts significantly contributed to the promotion of Chinese acupuncture within western medical communities. From the perspective of acupuncture humanities, this article reviews and analyzes Dimond's academic background, his journey to study acupuncture anesthesia in China, and his unique insights into acupuncture, exploring how his open-minded and objective approach facilitated the acceptance and dissemination of acupuncture anesthesia and acupuncture techniques in the West.

In June 1958, the first specialized acupuncture hospital, the Affiliated Acupuncture Experimental Hospital of Jiangsu Provincial School of TCM, was established in Nanjing. This hospital was founded under the initiative of Mr. CHENG Dan'an, the founder of the Chengjiang School of Acupuncture. Centered on clinical acupuncture, the hospital also carried out research and teaching, forming an integrated development model of medical care, education, and research. Its development experience, including a clear hospital-running philosophy, orientation toward solving clinical needs, and deep integration of medical care, education, and research, provides important historical references for the construction of modern specialized acupuncture hospitals.

Objective:To evaluate the histocompatibility and biomechanical properties of domestically produced abdominal wall segment polylactic acid absorbable microhook urethral sling in an animal model.Methods:Twenty four rabbits were divided into two groups: polylactic acid microhook sling group ( n=12) and TVT ABBREVO sling group ( n=12). Segments of the slings (abdominal wall portion and urethral portion) were implanted into the rabbit′s abdominal wall and the vesicovaginal space, respectively. Specimens were harvested via euthanasia at postoperative 0 day ( n=3 per group), 4 weeks ( n=3 per group) and 12 weeks ( n=6 per group) for simulated clinical fixation test, histomorphological observation (to evaluate histocompatibility), and biomechanical property analysis (tensile testing). Results:In the simulated clinical fixation test, the domestically produced abdominal wall segment polylactic acid absorbable microhook urethral sling maintained tight integration with the tissue without detachment across the range of abdominal pressure fluctuations associated with normal human activity (1-34 kPa); in contrast, TVT ABBREVO sling shifted and detached under pressure as low as 15 kPa. At 4 weeks post-implantation in the abdominal wall, none displacement occurred in polylactic acid microhook sling group (0/6 sites), whereas displacement occurred in 5 out of 6 in TVT ABBREVO sling group; at 12 weeks, displacement occurred in 4 out of 24 sites (17%) for polylactic acid microhook sling group, compared to 12 out of 24 sites (50%) for TVT ABBREVO sling group. These differences were statistically significant at both time points (both P<0.01). Tensile testing revealed that the sling of polylactic acid microhook sling group exhibited significantly lower thickness, tensile strength, and elongation percentage after implantation for 12 weeks compared to TVT ABBREVO sling group (all P<0.05). Histocompatibility: both sling types integrated well with host tissues after implantation subcutaneously in the abdominal wall and in the vesicovaginal space. Both induced a mild local inflammatory response. No pathological changes were observed in the surrounding tissues for either sling type, and there were no statistically significant differences in histopathological scores between the two groups (all P>0.05). Conclusions:The domestically produced abdominal wall segment polylactic acid absorbable microhook urethral sling demonstrates favorable histocompatibility. The polylactic acid microhooks significantly enhance the sling′s fixation to the tissue, effectively preventing early postoperative displacement caused by abrupt changes in abdominal pressure, and thus offer superior clinical applicability.

Objective To explore the anesthesia management experience in the interventional treatment of pediatric congenital heart diseases (CHD) percutaneously guided by transthoracic echocardiography (TTE) on a mobile operating platform. Methods From March to July 2023, a total of 13 patients from remote areas underwent interventional treatment for CHD on the mobile operating platform of Fuwai Yunnan Cardiovascular Hospital. Patients who received non-tracheal intubation general anesthesia were retrospectively included. Results Eight children who had difficulty cooperating with the surgery (due to young age, emotional tension, crying) received monitored anesthesia care with local anesthesia supplemented by sedative and analgesic drugs while maintaining spontaneous breathing under the monitoring and management of an anesthesiologist (i.e., non-tracheal intubation general anesthesia). Among them, there were 5 males and 3 females, with an age of (6.95±3.29) years and a body weight of (19.50±6.04) kg. Through transthoracic echocardiography, they were diagnosed with atrial septal defect (6 patients), residual shunt after patent ductus arteriosus ligation (1 patient), and severe pulmonary valve stenosis (1 patient). The surgery proceeded smoothly, with satisfactory anesthesia and surgical effects, complete analgesia, and satisfactory postoperative recovery. There was 1 patient of body movement and 1 patient of respiratory depression during the operation, and both patients completed the surgery successfully after treatment. All children had no serious surgery- and anesthesia-related complications. The anesthesia time was 40.5 (34.5, 47.5) min, the surgery time was 39.0 (33.0, 45.5) min, and the recovery time was 43.0 (28.0, 52.5) min Conclusion Interventional surgery for CHD guided by TTE at a mobile platform is a minimally invasive approach without radiation damage. Non-tracheal intubation general anesthesia with spontaneous breathing can be safely and effectively implemented in children who cannot cooperate.

[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 preliminarily assess the biocompatibility and durability of the TruDelta TM transcatheter mitral valve replacement (TMVR) system. Method:Six adult sheep were divided into 3 groups based on the duration of follow-up: 30 days ( n=1), 90 days ( n=3) and 180 days ( n=2). The TruDelta TM TMVR system was implanted through a transapical approach under transesophageal echocardiographic guidance. The operability of the TMVR system was evaluated using an instrument performance evaluation scale (consisting of 39 items), with scores ranging from 1 (worst) to 10 (best) assigned by the operator. Echocardiography was conducted preoperatively, immediately after surgery, and at 30, 90, and 180 days post-implantation. At the last follow-up time point, the intervention mitral valve membrane and major organs were dissected for observation. The artificial valves were taken for hematoxylin eosin (HE) staining and observed under a scanning electron microscope. Result:All six procedures were successfully completed using 29S size TruDelta TM TMVR device. At the final follow-up, echocardiogram demonstrated good valve function without obvious paravalvular leakage, with a transvalvular gradient of (7.8±3.2) mmHg (1 mmHg=0.133 kPa) and a mitral valve orifice area of (1.8±0.2) cm 2. Autopsy findings revealed no structural valve failure and almost complete endothelialization (>75%) with 90 to 180 days. Both HE staining and scanning electron microscopy confirmed optimal endothelialization of the valve stent. Conclusion:The preclinical animal study indicates that the TruDelta TM device exhibits favorable biocompatibility and durability.
