[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.

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toward solving clinical needs, and deep integration of medical care, education, and research, provides important historical references for the construction of modern specialized acupuncture hospitals.

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.

Professor Qiu Maoliang,in his clinical practice and experience summary of acupuncture-moxibustion in the treatment of febrile diseases,proposes four acupuncture-moxibustion antipyretic methods,namely,releasing the exterior and reducing fever,clear-ing the interior and purging the heat,nourishing the yin and purging the heat,and assisting the yang and reducing fever,which respec-tively correspond to the exterior heat syndrome,interior heat syndrome,yin deficiency fever syndrome,and yang deficiency fever syn-drome.The academic connotation of Professor Qiu Maoliang's acupuncture-moxibustion for fever can be summarized as examining the syndrome and seeking the cause,and classifying fever;coordinating the four methods of acupuncture-moxibustion and operation tech-niques,which reflect Professor Qiu Maoliang's academic characteristics,such as the convergence of Chinese and Western medicine,mutual learning of acupuncture-moxibustion and medicine,and the connection of effect mechanism and theory.Professor Qiu Ma-oliang's academic thought of acupuncture-moxibustion antipyretic method not only helps to provide basis for further application of acu-puncture-moxibustion in contemporary clinical practice,but also enriches the modern biological connotation of acupuncture-moxibus-tion medicine.

OBJECTIVE: To develop a noninvasive method for prediction of 1p/19q codeletion in diffuse lower-grade glioma (DLGG) based on multimodal magnetic resonance imaging (MRI) radiomics. METHODS: We collected MRI data from 104 patients with pathologically confirmed DLGG between October, 2015 and September, 2022. A total of 535 radiomics features were extracted from T₂WI, T₁WI, FLAIR, CE-T₁WI and DWI, including 70 morphological features, 90 first order features, and 375 texture features. We constructed logistic regression (LR), logistic regression least absolute shrinkage and selection operator (LRlasso), support vector machine (SVM) and Linear Discriminant Analysis (LDA) radiomics models and compared their predictive performance after 10-fold cross validation. The MRI images were reviewed by two radiologists independently for predicting the 1p/19q status. Receiver operating characteristic curves were used to evaluate classification performance of the radiomics models and the radiologists. RESULTS: The 4 radiomics models (LR, LRlasso, SVM and LDA) achieved similar area under the curve (AUC) in the validation dataset (0.833, 0.819, 0.824 and 0.819, respectively; P>0.1), and their predictive performance was all superior to that of resident physicians of radiology (AUC=0.645, P=0.011, 0.022, 0.016, 0.030, respectively) and similar to that of attending physicians of radiology (AUC=0.838, P>0.05). CONCLUSION Multiparametric MRI radiomics models show good performance for noninvasive prediction of 1p/19q codeletion status in patients with in diffuse lower-grade glioma.

ACC oxidase (ACO) is one of the key enzymes that catalyze the synthesis of ethylene. Ethylene is involved in salt stress response in plants, and salt stress seriously affects the yield of peanut. In this study, AhACO genes were cloned and their functions were investigated with the aim to explore the biological function of AhACOs in salt stress response, and to provide genetic resources for the breeding of salt-tolerant varieties of peanut. AhACO1 and AhACO2 were amplified from the cDNA of salt-tolerant peanut mutant M29, respectively, and cloned into the plant expression vector pCAMBIA super1300. The recombinant plasmid was transformed into Huayu22 by pollen tube injection mediated by Agrobacterium tumefaciens. After harvest, the small slice cotyledon was separated from the kernel, and the positive seeds were screened by PCR. The expression of AhACO genes was analyzed by qRT-PCR, and the ethylene release was detected by capillary column gas chromatography. Transgenic seeds were sowed and then irrigated with NaCl solution, and the phenotypic changes of 21-day-seedings were recorded. The results showed that the growth of transgenic plants were better than that of the control group Huayu 22 upon salt stress, and the relative content of chlorophyll SPAD value and net photosynthetic rate (Pn) of transgenic peanuts were higher than those of the control group. In addition, the ethylene production of AhACO1 and AhACO2 transgenic plants were 2.79 and 1.87 times higher than that of control peanut, respectively. These results showed that AhACO1 and AhACO2 could significantly improve the salt stress tolerance of transgenic peanut.

Objective:To evaluate the performance of Autoderm, an artificial intelligence application, in the diagnosis of skin diseases in Chinese patients.Methods:Totally, 920 patients with confirmed skin diseases were prospectively recruited in the Department of Dermatology, the First Affiliated Hospital of Zhengzhou University. Every patient provided 1 clinical image, which was uploaded onto the Autoderm application for the diagnosis of skin diseases. The diagnostic sensitivity, specificity and accuracy of the Autoderm application were estimated, and the kappa values for the diagnostic agreement between the Autoderm application and dermatologists were calculated.Results:Among the 920 patients, 871 (94.7%) could be diagnosed with an Autoderm′s in-distribution skin disease, whereas 49 (5.3%) had out-of-distribution skin diseases. According to the top 1 and 3 diagnoses given by the Autoderm application for the 920 patients separately, its mean diagnostic sensitivities were 41.8% and 65.8%, mean specificities 96.8% and 91.5%, and mean accuracies 92.9% and 89.9%, respectively, and there was moderate overall agreement between the Autoderm application and dermatologists (κ = 0.420, 0.464, respectively). However, for an out-of-distribution skin disease, the Autoderm application could output 5 definitely false diagnoses.Conclusion:Autoderm may be used as as clinical decision support tool for the diagnosis of common skin diseases in most Chinese patients, with moderate diagnostic sensitivity, high specificity, and high accuracy, but misdiagnosis may occur.

Objective:To analyze the long-term outcomes of different secondary surgeries in women with recurrent stress urinary incontinence (SUI) after Burch colposuspension.Methods:Between February 2004 to February 2010, five women with recurrent SUI after Burch colposuspension in Peking Union Medical College Hospital were retrospectively followed up, and the long-term outcomes of secondary surgeries were analyzed. Subjective cures of Burch colposuspension and secondary surgeries were assessed by patients′ self-reported incontinence symptoms and patient global impression of improvement questionnaire; objective cure, improvement or failure were determined by 1-hour pad test.Results:Three women underwent tension-free vaginal tape-retropubic (TVT) as the secondary surgery, one underwent tension-free vaginal tape-obturator (TVT-O), and one underwent single-incision tension-free vaginal tape-Secur (TVT-Secur). The follow-up period of five women was (14.6±2.4) years (range: 10.8 to 16.9 years). Three women undergoing TVT secondary surgery were subjectively cured; while the other two women undergoing TVT-O or TVT-Secur were not subjectively cured, but the woman undergoing TVT-O was objectively improved.Conclusions:It is feasible for women with recurrent SUI after Burch colposuspension to receive the secondary surgery. Our limited data suggests that TVT could be considered.

China is a country with high incidence of esophageal cancer. In recent years, with the deepening research, the value of neoadjuvant therapy in locally advanced resectable esophageal cancer has been widely approved by clinicians, compared with surgery alone or adjuvant therapy. However, the survival results of different neoadjuvant therapy options may be quite different, and many problems remain unresolved. In this article, a systemic literature review was carried out to summarize the radiotherapy target, radiotherapy dose, chemotherapy regimen of neoadjuvant chemoradiotherapy and time to surgery, as well as review the research status and progress on targeted therapy and immunotherapy as neoadjuvant therapy for esophageal cancer.

Objective:To explore the nursing effect of health education guided by trans-theoretical model combined with therapeutic communication in patients with vitiligo.Methods:A total of 120 patients with vitiligo who were admitted to Department of Dermatology in the First Affiliated Hospital of Zhengzhou University from February 2017 to June 2020 were selected and they were divided into the study group and the control group according to simple random number table method, with 60 cases in each group. Patients in both groups received conventional treatment. The control group was given therapeutic communication, while the study group was given trans-theoretical model-guided health education combined with therapeutic communication. Symptom Check List-90 (SCL-90) , Herth Hope Index (HHI) and The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) were used to investigate patients of the two groups before and after the intervention.Results:After intervention, the depression factors and anxiety factors of the SCL-90 scale in the study group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . After the intervention, the total score of the HHI scale and the score of each dimension of SF-36 scale of the study group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Health education guided by trans-theoretical model combined with therapeutic communication can effectively improve the mental state of patients with vitiligo and improve their treatment compliance, hope level and quality of life.
