Post-orgasmic illness syndrome (POIS) is a rare condition characterized by the rapid onset of extreme fatigue, flu-like symptoms, difficulty concentrating, depression, nasal congestion, rhinorrhea, itchy eyes, and other physical and psychological discomforts following ejaculation. This report presents the outcomes of two patients with POIS who underwent a two-year course of autologous seminal plasma subcutaneous cluster immunotherapy. Treatment efficacy was assessed using methods such as the symptom Visual Analogue Scale (VAS), the Union Physio-Psycho-Social Assessment Questionnaire (UPPSAQ)-70, and the Short Form 36 Health Survey (SF-36). The results suggest that autologous seminal plasma subcutaneous cluster immunother-apy may be a safe and effective therapeutic approach for POIS.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective To investigate anxious and depressive emotions in patients underwent cervical cancer surgery and to analyze its influencing factors.Methods A total of 304 patients who underwent primary cervical cancer surgery in Obstetrics and Gynecology Hospital,Fudan University from Oct 2018 to Jun 2021,were recruited to evaluate the clinical effect based on cervical cancer-patient reported outcome 137 scale(CC-PRO137 scale).This study focused on dimensions of depressive and anxious emotions within this scale and explored their influencing factors.Results The average scores of their depressive and anxious emotions within half a year after surgery were 4.141±0.798 and 4.020±0.616,respectively;and the average scores of depressive and anxious emotions more than one year after surgery were 4.250±0.802 and 4.097±0.613,respectively.By using statistical methods including analysis of variance and t test,it was found that there were statistically significant differences in the scores of depression and anxiety among cervical cancer patients under different postoperative adjuvant treatments and at different postoperative time points(P<0.05).However,there were no statistically significant differences in the scores of depression and anxiety among patients with different ages,surgical methods,and clinical stages of cervical cancer(P>0.05).Conclusion Patients underwent cervical cancer surgery may suffer varying degree of depressive and anxious emotions,and the main influencing factors are different adjuvant treatments and the length of time for postsurgical recovery.Medical practitioners should strengthen comfort and care for patients with cervical cancer,especially those who receive chemotherapy and radiotherapy treatments and are in the primary stage after the surgery.Formulating positive intervention measures can effectively reduce the psychological pain of patients and safeguard their physical and mental health.

Objective To propose a object detection method based on an improved YOLOv8 model to solve the problems of the inspection robot in low accuracy for recognizing pointer-type or obscured meters.Methods Firstly,a YOLOv8 model was chosen as the foundation object detection model,based on which the coordinate attention(CA)mechanism was introduced to enhance the model's understanding of the spatial structure of the input data over long distances;secondly,the original complete IoU(CIoU)loss function was replaced by an efficient IoU(EIoU)loss function to accelerate the convergence of the model's detection frame;finally,the soft non-maximum suppression(Soft-NMS)function took the place of the traditional NMS method to suppress the redundant bounding box smoothly and further improve the detection accuracy.The improved YOLOv8 model(YOLOv8nxt model)was compared with the YOLOv8n model to verify its efficacy for object detection.Results The YOLOv8nxt model with a size of 6.2 M had the position loss decreased by 1.3％,mAP_0.5∶0.95 increased by 1.7％,detection accuracy raised by 0.87％and detection time prolonged by only 0.2 ms when comparted with the YOLOv8n model.Conclusion The improved YOLOv8 model-based object detection method enhances the accuracy and speed of the inspection robot's recognition of meters during movement,and can effectively solve the problems of the inspection robot in the object detection stage.[Chinese Medical Equipment Journal,2024,45(3):1-8]

Objective To compare the effect of posterior cruciate ligament retaining(CR)and posterior cruciate substituting(PS)prosthesis in knee arthroplasty.Methods 64 patients with knee osteoarthritis were admitted to our department from June 2021 to June 2022 and whom met the selection criteria were randomly selected and divided into observation group and control group(n = 32).CR prosthesis was used in the observation group,and PS prosthesis was used in the control group.Operation time,postoperative drainage volume,difference of hemoglobin(HGB)before and after operation,postoperative hospital stay,postoperative range of motion at 7 d,14 d,45 d,3 months and 1 year were recorded.ROM,visual analog pain Scale(VAS),Hospital for special surgery(HSS)score,and maximum forward and backward displacement of knee joint and the regular radiographs were also recorded,too.Results The two groups were similar in terms of operation time,postoperative hospital stay,postoperative VAS score and maximum anterior and posterior displacement of knee joint,with P values greater than 0.05,which had no statistical significance.The postoperative drainage volume in the observation group was significantly less than that in the control group,with statistical significance(P＜0.05).The HGB difference of observation group was significantly lower than that of control group,with statistical significance(P＜0.05).There was no statistically significant differ-ence in ROM and HSS scores between the two groups before surgery;the ROM and HSS scores of the control group at 7,14 and 45 days after surgery was better than that of the observation group,with statistical significance(P＜0.05);the ROM and HSS scores of the two groups at 3 months after surgery was not statistically significant.The ROM and HSS scores in the observation group was better than that in the control group at 6 months and 1 year after operation,and the difference was statistically significant(P＜0.05).Conclusions CR prosthesis is superior to PS prosthesis in terms of intraoperative blood loss and post-operative drainage volume,which can reduce surgical risk.Both kinds of prosthesis can achieve good knee stability after surgery,while PS prosthesis has better early clinical effect,while CR prosthesis has better long-term clinical effect.

Histone acetylation and methylation can affect chromatin conformation and regulate a variety of biological activities.Abnormal histone acetylation and methylation modifications are related to the occurrence and development of a variety of oral diseases.Histone acetylation and methylation increase or decrease in an orderly manner to regulate the development of teeth.Fluoride ions can destroy the balance between histone acetylation and methylation,which may be related to the occurrence of dental fluorosis.In addition,histone acetylation and methylation are involved in the regula-tion of oral inflammatory diseases.In the inflammatory microenvironment,the expression of histone acetyltransferase GCN5 decreases,and the expression of Dickkopf 1(DKK1)decreases,activating the Wnt/β-catenin pathway and ulti-mately inhibiting the osteogenic differentiation of periodontal ligament stem cells.Enhancer of zeste homolog 2(EZH2)and H3K27me3 levels were decreased in inflamed dental pulp tissues and cells.EZH2 inhibition inhibited the expres-sion of interleukin(IL)-1b,IL-6 and IL-8 in human dental pulp cells under inflammatory stimulation.Histone acetyla-tion/methylation modifications can interact with multiple signaling pathways to promote the occurrence and development of oral tumors and are related to the high invasiveness of salivary gland tumors.Small molecule drugs targeting histone acetylation and methylation-related enzymes can regulate the level of histone methylation/acetylation and have shown po-tential in the treatment of oral and maxillofacial diseases.For example,the histone deacetylase inhibitor vorinostat can inhibit the secretion of inflammation-related cytokines;it also promotes the maturation of odontoblasts and the formation of dentin-related matrix,demonstrating its potential in pulp preservation.Understanding the role of histone acetylation/methylation modifications in the occurrence and development of oral diseases will help promote research on epigenetic modifications in oral diseases and provide new perspectives for disease diagnosis and treatment.

Objective:To explore the problems of medical and preventive integration at primary healthcare institutions in China, for references for promoting the development of medical and preventive integration in China.Methods:This study searched for literatures covering the integration of medical and preventive at primary healthcare institutions on CNKI, Wanfang, and VIP databases(from the establishment of the database until March 1, 2023), and extracted text mentioning problems of the medical and preventive integration in primary healthcare institutions. The macro model of the health system was used for problem classification analysis, while the social network analysis method was used to measure the network density, point centrality, and intermediary centrality of the problem, and determine the key issues.Results:A total of 25 papers were included, and 28 problems of medical and preventive integration at primary medical and health institutions were extracted, including 6 problems at the external environment level, 15 problems at the structural level, 6 problems at the process level, and 1 problem at the result level. The results of social network analysis showed that the network density of these problems was 0.71. The point centrality and intermediary centrality of key problems were both high, including the lack of incentive mechanisms for medical and prevention integration (point centrality=69, intermediary centrality=21.44), fragmentation of health information systems(68, 15.70), insufficient awareness of medical and prevention integration among grassroots personnel(65, 17.47), shortage of talent at primary medical and health institutions(64, 11.69), weak service capabilities of primary medical institutions(50, 19.23), and insufficient information sharing(48, 15.80).Conclusions:A variety of problems were found in the integration of medical and preventive at primary medical and health institutions in China, which were closely interrelated. It was urgent to solve six key problems, including the lack of incentive mechanisms, talent shortage, and information system fragmentation, etc. It was suggested that primary medical and health institutions should further improve the incentive mechanism for medical and preventive integration, strengthen the construction of grassroots health talent teams, promote health information exchange and sharing, and enhance the awareness of medical and preventive integration.

Fibrosis is a repair response initiated by tissues and organs after injury, and is a self-protection mechanism of the body. It has been found that endothelium-to-interstitial transdifferentiation (EndMT) is involved in the physiological and pathological processes of various organ fibrosis, which has become a focus of the research on fibrotic diseases. In recent years, the study has found that EndMT plays an important role in many pathological processes in cardiovascular system, lungs, kidneys, liver, pancreas fibrosis, and so on. This article summarizes EndMT regulatory mechanism and its role in each organ fibrosis, as well as the related treatment progress of EndMT targets, so as to provide new targets for prevention and control of organ fibrosis.
