Chen Shigong is a renowned traditional Chinese medical surgeon in the Ming Dynasty， and his medical ethical thought is an important part of ancient Chinese medical ethical thought. The “five precepts of physicians” and the “ten essentials for physicians” in his book Orthodox Manual of External Diseases are regarded as the third monument in the history of the development of traditional Chinese medical ethics. Chen Shigong’s medical ethical thought was mainly influenced by the Song and Ming philosophies， forming the worldview of “unity of heaven and humanity” and a philosophy of life of “unity of knowledge and action.” He also advocated the values of benevolence among physicians and indifference to fame and fortune， the doctor-patient view of treating patients equally and preserving privacy， the medical view of respecting peers and spreading medical skills， and the diagnosis and treatment view of fulfilling duties and treating patients based on syndrome differentiation. Chen Shigong’s medical ethical thought advocated that medical ethics and skills should be given equal importance， which has a strong vitality and important reference value in strengthening medical ethical education， improving doctor-patient relationships， and cultivating the spirit of “benevolence” among physicians.

ObjectiveTo examine the public cognition， preferences， and values regarding organ allocation， thereby enhancing the public trust in China’s organ allocation system and providing a theoretical basis for human organ allocation in China. MethodsBy drawing on foreign questionnaires and finalizing the questionnaire after two rounds of expert discussion and evaluation， a nationwide online survey was conducted to investigate the Chinese public’s cognition， attitudes， and preferences towards organ allocation. ResultsNearly half of the respondents reported that they had only heard of （45.44%） or had never heard of （46.90%） the Organ Procurement Organizations （OPOs）. Most respondents expressed limited understanding of China’s organ allocation policy （68.42%） or specific procedures （67.89%）. Only 9.65% of respondents expressed strong support for the current organ allocation policy， while 75.76% indicated that national allocation policies would influence their willingness or decision to donate organs. The public showed stronger endorsement of the principles of “prioritizing the sickest，” “first-come， first-served，” and “prioritizing those with better prognosis” for organ allocation. There were statistically significant differences in the public cognition， attitudes， and preferences for organ allocation by gender， age， education level， and occupation （all P<0.05）. ConclusionThe Chinese public’s cognition regarding organ allocation is generally low， and their willingness to donate organs is not high. The public attitude towards organ allocation policy remains unclear and is still in a “wait-and-see” state； the public prefers an ethical distribution model that balances fairness and efficiency. Increasing the public understanding of organ allocation procedures and incorporating public opinion into national organ allocation guidelines could play a significant role in enhancing public willingness to donate organs.

Objective To investigate the characteristics of traditional Chinese medicine(TCM)syndrome elements and the distribution patterns of TCM syndromes in senile osteoporosis(SOP),providing a reference for TCM treatment of SOP.Methods A cross-sectional study was conducted on 200 SOP patients aged over 70 years treated at Wuxi Huishan Chinese Medicine Hospital from January 2022 to June 2023.General information and TCM diagnostic data were collected.The syndrome element differentiation scoring method was employed for analysis.Results(1)Among the 200 SOP patients,the most prevalent disease-location syndrome element was kidney(61.50％),followed by liver(48.50％),bones and tendons(45.50％),spleen(37.00％),meridians(25.50％),heart(12.50％),and lung(10.50％).Statistical analysis showed significantly higher syndrome element scores for kidney,liver,bones and tendons,spleen,and meridians compared to heart and lung(P＜0.01).(2)Regarding disease-nature syndrome elements,deficiency-type elements predominated,with yang deficiency(52.50％)being most common,followed by blood deficiency(46.00％),essence depletion(45.50％),qi deficiency(45.50％),yin deficiency(37.00％),unconsolidation(25.50％),and qi sinking(15.50％).Yang deficiency,blood deficiency,essence depletion,qi deficiency,and yin deficiency scores were significantly higher than those of insecurity and qi sinking,the difference being statistically significant(P＜0.01).Among excess-type elements,cold(47.00％)was most prevalent,followed by blood stasis(45.00％),qi stagnation(43.50％),dampness(34.50％),phlegm(27.50％),and heat(25.00％).Cold and blood stasis scores were significantly higher than phlegm,while cold,blood stasis,qi stagnation,dampness,and phlegm scores were significantly higher than heat,the difference being statistically significant(P＜0.05).(3)Eighteen TCM syndrome patterns were identified.Spleen-kidney yang deficiency(40.00％)was most frequent,followed by liver blood deficiency(37.50％),kidney essence insufficiency(35.00％),qi stagnation and blood stasis(31.00％),cold congelation and obstruction(25.50％),phlegm-damp obstruction(27.50％),and qi-yin deficiency with qi insecurity(11.00％).Based on syndrome element scores,the primary syndromes were defiined as spleen-kidney yang deficiency(35.60％),liver blood deficiency(25.13％),kidney essence insufficiency(18.32％),and qi stagnation and blood stasis(13.09％),etc.Conclusion The characteristic TCM syndrome elements of SOP patients involve qi-blood-yin-yang deficiency of kidney,spleen,and liver,combined with cold congelation,blood stasis,and qi stagnation.The main TCM syndromes are spleen-kidney yang deficiency,liver blood deficiency,kidney essence insufficiency,and qi stagnation with blood stasis.

Objective To evaluate early outcomes of transthoracic pulmonary valve implantation for the treatment of moderate and severe pulmonary regurgitation by using homemade self-expanding valve (SalusTM). Methods Patients with severe pulmonary regurgitation who underwent transthoracic pulmonary valve implantation in Guangdong Provincial People’s Hospital from September 2, 2021 to November 25, 2022 were prospectively enrolled. The early postoperative complications and improvement of valve and heart function were summarized and analyzed. Results A total of 25 patients were enrolled, including 16 males and 9 females, with an average age of 24.5±1.5 years and an average weight of 57.0±3.0 kg. The mean systolic diameters of the bifurcation near the main pulmonary artery, the stenosis of the middle segment of the aorta and near the valve of the right ventricular outflow tract of the patients were 31.8±7.4 mm, 30.6±5.9 mm and 38.4±8.0 mm, respectively. All patients were successfully implanted with valves, and there were no serious complications such as death, coronary compression, stent fracture, valve displacement and infective endocarditis in the early postoperative period. The indexed left atrial longitudinal diameter, indexed right atrial longitudinal diameter, and indexed right ventricular outflow tract anteroposterior diameter decreased significantly after the operation. The degree of tricuspid and pulmonary valve regurgitation and the indexed regurgitation area decreased significantly. The above differences were statistically significant (P<0.05). Conclusion The early outcomes of transthoracic pulmonary valve implantation with homemade self-expanding pulmonary valve (SalusTM) in the treatment of severe pulmonary regurgitation is relatively good, and the long-term outcomes need to be verified by the long-term follow-up studies with large samples.

Objective: The aim of this study was to determine the poly (ADP-ribose) polymerase inhibitors (PARPis) response and outcome of ovarian cancer (OC) patients with BRCA1/2 germline mutation and a history of breast cancer (BC). Methods: Thirty-nine OC patients with BRCA1/2 germline mutation and a history of BC were included. The clinicopathological characteristics, PARPis response and prognosis were analyzed. Results: The median interval from BC to OC diagnosis was 115.3 months (range=6.4–310.1).A total of 38 patients (38/39, 97.4%) received platinum-based chemotherapy after surgical removal. The majority of these patients were reported to be platinum sensitive (92.1%, 35/38).21 patients (53.8%) received PARPis treatment with 16 patients (76.2%) for maintenance treatment and 5 patients (5/21, 23.8%) for salvage treatment. The median duration for PARPis maintenance and salvage treatment was 14.9 months (range=2.0–56.9) and 8.2 months (range=5.2–20.7), respectively. In the entire cohort, 5-year progression-free survival (PFS) and overall survival (OS) rate was 33.1% and 78.9%, respectively. Patients with BRCA1 mutation had a non-significantly worse 5-year PFS (28.6% vs. 45.8%, p=0.346) and 5-year OS (76.9% vs.83.3%, p=0.426) than those with BRCA2 mutation. In patients with stage III–IV (n=31), first line PARPis maintenance treatment associated with a non-significantly better PFS (median PFS: NR vs. 22.4 months; 5-year PFS: 64.3% vs. 21.9%, p=0.096). Conclusion The current study shows that these patients may have a good response to platinum-based chemotherapy and a favorable survival. And these patients can benefit from PARPis treatment and will likely be suitable candidates for PARPis.

Rosuvastatin(RVS)is an excellent drug with anti-inflammatory and lipid-lowering properties in the aca-demic and medical fields.However,this drug faces a series of challenges when used to treat atherosclerosis caused by hyperhomocysteinemia(HHcy),including high oral dosage,poor targeting,and long-term toxic side effects.In this study,we applied nanotechnology to construct a biomimetic nano-delivery system,macrophage membrane(M?m)-coated RVS-loaded Prussian blue(PB)nanoparticles(MPR NPs),for improving the bioavailability and targeting capacity of RVS,specifically to the plaque lesions associated with HHcy-induced atherosclerosis.In vitro assays demonstrated that MPR NPs effectively inhibited the Toll-like receptor 4(TLR4)/hypoxia-inducible factor-1α(HIF-1α)/nucleotide-binding and oligomerization domain(NOD)-like receptor thermal protein domain associated protein 3(NLRP3)signaling pathways,reducing pyroptosis and inflammatory response in macrophages.Additionally,MPR NPs reversed the abnormal distribution of adenosine triphosphate(ATP)-binding cassette transporter A1(ABCA1)/ATP binding cassette transporter G1(ABCA1)/ATP binding cassette transporter G1(ABCG1)caused by HIF-1α,promoting cholesterol efflux and reducing lipid deposition.In vivo studies using apolipoprotein E knockout(ApoE-/-)mice confirmed the strong efficacy of MPR NPs in treating atherosclerosis with favorable bio-security,and the mechanism behind this efficacy is believed to involve the regulation of serum metabolism and the remodeling of gut microbes.These findings suggest that the synthesis of MPR NPs provides a promising nanosystem for the targeted therapy of HHcy-induced atherosclerosis.
