"Chinese model" of organ donation and transplantation in China has won acclaims from all over the world. Current contradictions between unbalanced and inadequate development of organ donation and transplantation and surging public demands for transplant services remain serious. And an acute shortage of donated organs is still the greatest difficulty. Improving organ donation rate per million population (PMP) and organ utilization rate has been a great challenge for organ donation teams in China. This review summarized the relevant experiences of Second Affiliated Hospital of Guangxi Medical University in fostering organ donation culture atmosphere and connotation to accelerate the high-quality development of organ donation. It was intended to provide references for disciplined construction of other organ donation management teams and promote the development of organ donation and transplantation in China.

Objective To investigate the relationship between coronary artery plaque AI quantitative parameter and FFR-CT in coronary computed tomography angiography.Methods A total of 84 patients suspected of having CAD[52 males and 32 females,aged 27 to 81 years with a mean age of(58.1±11.9)years]were enrolled in this study.All patients underwent coronary computed tomography angiography.The CCTA data was processed using shukun(SK)software for labeling and analysis of the coronary arteries,as well as obtaining quantitative parameters of coronary artery plaque AI and corresponding FFR-CT values.The quantitative parameters included plaque length,total volume,minimum lumen area(MLA),minimal lumen degree(MLD),lipid composition volume and proportion,fibrous-lipid composition volume and proportion,fibrous composition volume and proportion,calcified composition volume and proportion.Coronary artery hemodynamic abnormality or myocardial ischemia was defined as an FFR-CT value≤0.8.Correlational analysis was performed to evaluate the association between AI plaque quantitative param-eters and FFR-CT values.Univariate and multivariate binary logistic regression analyses were conducted to identify independent risk factors for predicting FFR-CT≤0.8.The predictive performance of the model based on AI plaque quantitative parameters was assessed using receiver operating characteristic(ROC)curve analysis and calculation of the area under the curve(AUC).Sensitivities,specificities,diagnostic test accuracy rates were also calculated.Results The predominant symptoms observed in the cohort of 84 patients were chest pain(n=39,46.4%)and distress(n=27,32.1%).Spearman analysis results revealed a weak positive correlation between FFR-CT and MLA(r=0.49,P<0.0001),while weak negative correlations were found for plaque length,total volume,lipid composition volume,fibrous-lipid composition volume,fibrous composition volume,and calcified composition volume(r=-0.44,-0.56,-0.40,-0.36,-0.42,-0.40;all P<0.05).Additionally,MLD exhibited a moderate negative correlation with FFR-CT(r=-0.60,P<0.0001).In the univariate binary logistic regression analysis,several variables including plaque length,total volume,MLA,MLD,lipid composition volume,fibrous-lipid composition volume,fibrous composition volume,and calcified composition volume were found to be independently associated with FFR-CT≤0.8(All P<0.05).The adjusted multivariate binary logistic regression analysis model revealed that MLD was the sole independent predictor(OR=1.082,95%CI:1.034～1.133,P=0.001).The logistics re-gression model expression was logit(P)=0.079X1-4.052,where X1 represents the value of MLD and achieved a predictive accuracy of 85.2%.The ROC AUC of plaque length,total volume,MLA,MLD,lipid composition vol-ume,fibrous-lipid composition volume,fibrous composition volume and calcified composition volume were 0.796,0.886,0.711,0.754 and 0.698 respectively,and the coresponding sensitivities and specificities were 47.83%,73.91%,73.90%,52.17%,60.87%and 92.11%,73.68%,60.53%,84.21%,89.47%.The five in-dexes combined diagnostic model possessed the largest AUC of 0.906,and 73.91%,71.05%of sensitivity and specificity.Conclusion The AI quantitative parameters of coronary artery plaque exhibited varying degrees of correlation with FFR-CT,while MLD emerged as the sole independent predictor of FFR-CT≤0.8,demonstrating high diagnostic efficiency.

Objective To investigate the habits of eye rubbing and sleeping posture of patients with keratoconus(KC)and analyze the correlation of the onset and severity of KC with eye rubbing and sleeping posture.Methods In this retrospective case-control study,KC patients who received diagnosis and treatment in the Eye Hospital of Shandong First Medical University from January 2018 to June 2022 were collected as the KC group,and myopia patients with matching ages and sexes who visited our hospital from February to June 2022 were recruited as the control group.All patients were inves-tigated by questionnaire and the details of eye rubbing,sleeping posture and related habits were recorded.According to the severity of the disease(corneal curvature),KC patients were divided into different stages,and the eye rubbing and sleep-ing posture of KC patients in different stages were compared.Results In this study,406 KC patients and 394 myopia pa-tients were included.It was found that 67.98％of KC patients and 24.87％of myopia patients rubbed their eyes,with a sig-nificant difference(P＜0.001);45.32％of KC patients and 24.87％of myopia patients were accustomed to sleeping on their side or stomach,with a significant difference(P＜0.001).The multivariate binary logistic regression analysis indica-ted that the following variables showed significant differences:patients with eyes at the later stages(steeper eyes)were more likely to rub eyes[odds ratio(OR)=3.547,95％CI:2.02-6.24,P＜0.001],sleep on side or stomach(OR=10.725,95％CI:5.77-19.94,P＜0.001),and turn head to the steeper eye when sleeping(OR=12.171,95％CI:7.23-20.49,P＜0.001).The statistical analysis demonstrated that the proportion of KC patients at the IV stage who were habitu-ated to rub their steeper eyes and turn their heads to the steeper eyes when sleeping was significantly higher than that of pa-tients at stages Ⅰ to Ⅲ(all P＜0.001).Conclusion Eye rubbing and sleeping on the side or stomach are risk factors for the onset of KC and are related to the severity of the disease.

Objective:To explore the efficacy and influencing factors of irinotecan-loaded CalliSpheres drug-eluting bead-transcatheter arterial chemoembolization (DEBIRI-TACE) combined with regorafenib in the third-line or above treatment of unresectable colorectal cancer liver metastases.Methods:From June 2018 to June 2020, 53 patients with unresectable colorectal cancer liver metastases admitted to Linyi Cancer Hospital of Shandong Province who had failed at least second-line systemic chemotherapy were retrospectively analyzed. The patients were divided into observation group (24 cases) and control group (29 cases) according to different treatment regimes. The control group only received regorafenib monotherapy, and the observation group received regorafenib combined with DEBIRI-TACE. According to the modified Response Evaluation Criteria in Solid Tumors, the objective response rate (ORR) and disease control rate (DCR) were evaluated, and the progression-free survival (PFS) and overall survival (OS) were estimated by Kaplan-Meier method. The Cox proportional hazards model was used to analyze the OS influencing factors in the observation group. The treatment related adverse reactions were observed.Results:After 2 months of treatment, the ORR of the observation group was 75.0% (18/24) , and the DCR was 91.7% (22/24) , both were higher than those of the control group [6.9% (2/29) and 51.7% (15/29) respectively], with statistically significant differences ( χ2=25.92, P<0.001; χ2=9.94, P=0.002) . There were no statistically significant differences in the incidences of regorafenib-related adverse reactions such as hand-foot skin reaction [62.5% (15/24) vs. 65.5% (19/29) , χ2=0.05, P=0.819], fatigue [41.7% (10/24) vs. 44.8% (13/29) , χ2=0.05, P=0.817], hypertension [29.2% (7/24) vs. 34.5% (10/29) , χ2=0.17, P=0.679], diarrhea [25.0% (6/24) vs. 27.6% (8/29) , χ2=0.04, P=0.832], hoarseness [16.7% (4/24) vs. 17.2% (5/29) , χ2=0.01, P=0.956] and proteinuria [8.3% (2/24) vs. 10.3% (3/29) , χ2=0.06, P=0.803] between the two groups. The main adverse reactions related to DEBIRI-TACE in the observation group were fever, pain, nausea and vomiting, etc., which were relieved after symptomatic treatment. No serious complications such as ectopic embolism of CalliSpheres drug eluting bead occurred. By the end of the follow-up, among the 24 patients in the observation group, the median OS of patients with simultaneous liver metastases was 12 months, and that of patients with metachronous liver metastases was 22 months, with a statistically significant difference ( χ2=4.29, P=0.026) . The median OS of patients with 3-5 liver metastases was 21 months, and that of patients with more than 5 liver metastases was 14 months, with a statistically significant difference ( χ2=3.35, P=0.040) . The median OS of Child-Pugh grade A patients was 22 months, and that of Child-Pugh grade B patients was 13 months, with a statistically significant difference ( χ2=4.22, P=0.027) . The median OS was 16 months in patients with extrahepatic metastases and 23 months in patients without extrahepatic metastases, with a statistically significant difference ( χ2=7.68, P=0.013) . Cox proportional hazards model analysis showed that simultaneous liver metastases ( HR=1.59, 95% CI: 1.02-2.47, P=0.031) and extrahepatic metastases ( HR=1.61, 95% CI: 1.29-2.01, P=0.020) were independent risk factors influencing OS of patients in the observation group. The median PFS of the observation group was 9 months, and that of the control group was 5 months, with a statistically significant difference ( χ2=7.78, P=0.005) . The median OS of the observation group was 17 months, and that of the control group was 11 months, with a statistically significant difference ( χ2=16.81, P<0.001) . Conclusion:DEBIRI-TACE combined with regorafenib is effective in the third-line or above treatment of unresectable colorectal cancer liver metastases, with tolerable adverse reactions. It is a safe and feasible treatment method. The prognosis of patients with simultaneous liver metastases or extrahepatic metastases is worse.

Osteoporosis and chronic psychological stress are two serious chronic degenerative diseases that cause disability and impact population health. Patients with osteoporosis often present with heavier psychological burden, lower quality of life, and frequent symptoms of depression and anxiety. There are potential common pathogenic factors, cellular mechanisms and signaling pathways between them. Considering that the number of patient with these diseases is huge and growing rapidly, it is particularly important to explore the pathogenic link between these two diseases as well as cross-effect therapeutics for osteoporosis and mental health disorders.

Organ shortage is one of the important factors restricting the development of human organ transplantation. The identification and referral of potential donors determine the total scale of organ donation. Whether potential donors can be identified and referred is the most important reason for the difference of organ donation rates in different regions. This paper interprets the chapter of the identification and referral of potential donors in the Guide to the Quality and Safety of Organs for Transplantation (6th edition) issued by European Union in order to provide reference for the staff of organ procurement organization and related medical personnel in China and improve the organ donation rate in China.

Objective By analyzing the perioperative management in our hospital to explore the clinical effect and safety of single kidney transplantation from deceased juveniles' donors.Methods We retrospectively analyze 86 cases of kidney transplantations from deceased juveniles' donors in our hospital from 2007 December to 2015 August.Results The success rate of the operations was 100％.The postoperative complications occurred as fellows:7 cases of acute rejection (8.14％);10 cases of drug intoxication (11.62％);21 cases of DGF (24.44％),4 cases of leakage of urine (4.65％),7 cases of lung infection (8.14％).Two cases (2.32％) died after the operation because of serious lung infection,and by corresponding treatment 47 cases recovered after 2-4 weeks.The creatinine level in 37 cases without any complications was 131.88 ± 44.20 μmol/L during discharge.Conclusion With strict selection,the organ from a deceased juvenile donor is safe and practicable.

Cytology in China developed from nothing and underwent a long journey from gynecologic cytology to that of all organs, laying a solid foundation for new developments in the 21st century. Thyroid fine-needle aspiration (FNA) was primarily developed in an endocrinology department and then in the clinical laboratory department or pathology department in the 1970–80s. Wrights staining is popular in endocrine and clinical laboratory departments, while hematoxylin and eosin staining is common in pathology. Liquid based cytology is not common in thyroid FNA cytology, while BRAF(V600E) mutation analysis has been the most popular molecular test. The history and practice of thyroid FNA practice in China were reviewed based on retrospective study of the practice in Qilu Hospital of Shandong University.
