Objective To investigate the current status,evolving hotspots,and emerging trends in the field of human re-source allocation research in public hospitals,both domestically and internationally,to provide a reference for future research di-rections in China.Methods CiteSpace was used to conduct a visual analysis of the research literature on human resource alloca-tion in public hospitals based on China National Knowledge Infrastructure(CNKI)and the Web of Science(WOS).The analysis encompassed co-authorship,institutional collaboration,keyword co-occurrence and clustering,and burst detection.Results A total of 1 417 Chinese articles and 981 international articles were included.Domestic research in this field focused more on healthcare reform and management,resource allocation,hierarchical diagnosis,and treatment,and informatization and efficiency improvement.On the contrary,international research primarily centered on the employee satisfaction,healthcare system quality,work environment and medical staff.Future trends in domestic research included cost reduction,efficiency enhancement,and a greater emphasis on public welfare in public hospitals,while international research was beginning to explore the influence of polit-ical concepts in this field.Conclusion Compared to international research,domestic research needs to further improve its theo-retical and localized understanding,broaden its research scope,explore the interdisciplinary collaboration opportunities,and delve into research directions such as the application of artificial intelligence and automation technology in healthcare services,management of a diverse workforce,and innovative management techniques and applications.

Objective:To study the localization value of stereoelectroencephalography (SEEG) in refractory epilepsy associated with tuberous sclerosis complex (TSC), and to analyze the prognosis related factors.Methods:A case control study.Data of 66 patients with TSC-related refractory epilepsy who underwent SEEG placement at the Epilepsy Center of Tsinghua University Yu-Quan Hospital from January 2014 to March 2023 were retrospectively analyzed, including medical history, seizure semiology, scalp electroencephalogram (EEG), imaging, and SEEG findings.Patients were divided into a seizure-free group and a seizure group according to the seizures after surgery. t/ χ2 test was used to compare the relationship between age of onset, age of surgery, duration of epilepsy, genetic findings, seizure symptoms, scalp EEG characteristics, SEEG placement protocol and prognosis. Results:A total of 66 patients met the enrollment criteria, of whom 55 patients were seizure-free after surgery (seizure-free group), and 11 patients still had seizures (seizure group).Among the 66 patients, there were 46 males and 20 females; the age of onset was (21.72±30.01) months; the age of SEEG surgery was (6.79±5.12) years; the duration of epilepsy was (4.98±4.11) years.SEEG results showed that seizures started with a single tuber in 43 patients (64.4%), seizures started with 2 or more tubers in one hemisphere in 16 patients, and 7 patients had bilateral multi-tubers or the pathogenic tuber(s) could not be identified.The following factors were found to be associated with prognosis: early age of surgery ( t=-3.463, P<0.01), ictal scalp EEG with a definite lateralization ( χ2=7.876, P<0.05), and the concordance of interictal and ictal EEG ( χ2=6.821, P<0.05).The age of onset, duration of epilepsy, seizure type and symptom, genetic findings, and SEEG placement protocol were not significantly correlated with prognosis.The results of SEEG identified that onset with a single tuber revealed a better postoperative outcome. Conclusions:This study confirms the safety and efficacy of SEEG in TSC-related refractory epilepsy, and also finds that ictal EEG is uniquely valuable in guiding SEEG placement for TSC-related refractory epilepsy, which can help us better select patients with TSC-related refractory epilepsy who are suitable for SEEG placement.

Objective:Non-alcoholic fatty liver disease(NAFLD)has significant genetic susceptibility.Adipocytokines play a crucial role in NAFLD development by participating in insulin resistance and hepatic steatosis.However,the association between adipocytokine pathway genes and NAFLD remains unclear.This study aims to explore the association of gene polymorphisms in the adipocytokine pathway and their interactions with NAFLD in obese children. Methods:A case-control study was conducted,dividing obese children into NAFLD and control groups.Peripheral venous blood(2 mL)was collected from each participant for DNA extraction.A total of 14 single nucleotide polymorphisms(SNP)in the adipocytokine pathway were genotyped using multiplex PCR and high-throughput sequencing.Univariate and multivariate Logistic regression analyses were used to assess the association between SNP and NAFLD in obese children.Dominant models were used to analyze additive and multiplicative interactions via crossover analysis and Logistic regression.Generalized multifactor dimensionality reduction(GMDR)was used to detect gene-gene interactions among the 14 SNPs and their association with NAFLD in obese children. Results:A total of 1 022 children were included,with 511 in the NAFLD group and 511 in the control group.After adjusting for age,gender,and BMI,multivariate Logistic regression showed that PPARG rs1801282 was associated with NAFLD in the obese children in 3 genetic models:heterozygote model(CG vs CC,OR=0.58,95%CI 0.36 to 0.95,P=0.029),dominant model(GG+CG vs CC,OR=0.62,95%CI 0.38 to 1.00,P=0.049),and overdominant model(CC+GG vs CG,OR=1.72,95%CI 1.06 to 2.80,P=0.028).PRKAG2 rs12703159 was associated with NAFLD in 4 genetic models:heterozygous model(CT vs CC,OR=1.51,95%CI 1.10 to 2.07,P=0.011),dominant model(CT+TT vs CC,OR=1.50,95%CI 1.10 to 2.03,P=0.010),overdominant model(CC+TT vs CT,OR=0.67,95%CI 0.49 to 0.92,P=0.012),and additive model(CC vs CT vs TT,OR=1.40,95%CI 1.07 to 1.83,P=0.015).No significant multiplicative or additive interaction between PPARG rs1801282 and PRKAG2 rs12703159 was found in association with NAFLD.GMDR analysis,adjusted for age,gender,and BMI,revealed no statistically significant interactions among the 14 SNPs(all P>0.05). Conclusion:Mutations in PPARG rs1801282 and PRKAG2 rs12703159 are associated with NAFLD in obese children.However,no gene-gene interactions among the SNP are found to be associated with NAFLD in obese children.

Adipose progenitor cells(APCs) represent a prominent stromal cellular component of adipose tissue and are now identified as highly heterogenous populations. However, the role of APCs in regulating systemic metabolism remains unknown. Using single cell RNA-sequencing, we investigated the role of the APC subpopulations in regulating development of type 2 diabetes. CD9 + CD55 low APCs are the novel subset identified in this study, which is significantly increased in type 2 diabetic patients. Transplantation of these cells from type 2 diabetic patients into adipose tissue caused glycemic disturbance in mice. Depletion of pathogenic APCs improved obesity-related glycemic disturbance. Collectively, our data provide deeper insights into human APC functionality and highlights APCs as a potential therapeutic target to combat type 2 diabetes. This study has been published in Nature Communications, 2024, 15(1): 4827.

Objective To observe the effect of dapagliflozin on cardiac function in patients with heart failure after emergency percutaneous transluminal coronary intervention in acute ST segment elevation myocardial infarction. Methods A total of 100 patients with acute myocardial infarction underwent emergency PCI were randomly divided into study group (52 cases) and control group (48 cases). The study group was given dapagliflozin on the basis of standardized treatment of myocardial infarction, and the control group was given conventional treatment of myocardial infarction. Cardiac ultrasound related indexes[left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic volume (LVEDV)], plasma N-terminal brain natriuretic peptide (NT-proBNP) level, 6-minute walking test (6MWT) results. The incidence of adverse reactions and major cardiovascular adverse events (MACE) were compared between the two groups during follow-up. Results After 6 months of treatment, LVESD, LVEDD and LVEDV in the two groups were significantly lower than before treatment, and LVEF was significantly higher than before treatment (P < 0.05); the LVESD, LVEDD and LVEDV of the study group were significantly lower than those of the control group, and LVEF was significantly higher than that of the control group (P < 0.05). The NT-proBNP in the two groups was significantly lower than before treatment, and was significantly lower in the study group than that in the control group (P < 0.05). The 6MWT distance of the study group was significantly longer than that of the control group (P < 0.05). There was no significant difference in the incidence of adverse reactions and MACE between the two groups (P>0.05). Conclusion Dapagliflozin can improve cardiac function in patients with heart failure after emergency PCI of acute ST segment elevation myocardial infarction.

Objective:To record stereoelectroencephalography (SEEG) data and to induce cortical electrical stimulation in children with tuberous sclerosis complex (TSC), thus exploring the epileptogenicity of different types of cortical tubers.Methods:The SEEG recording and cortical electrical stimulation data of 50 children with TSC who underwent preoperative evaluation for drug-resistant epilepsy at Epilepsy Center, Tsinghua University Yuquan Hospital from November 2016 to September 2022 were retrospectively analyzed, involving 27 boys and 23 girls with the age of (5.5±3.4) years.According to the results of 3.0T magnetic resonance imaging (3T-MRI) and computed tomography(CT), cortical tubers were classified.The incidences of electroclinical seizures, electrical seizures and seizures induced by cortical electrical stimulation in different types of tubers recorded by SEEG were analyzed, and the differences in the proportion of the above seizures among different types of tubers were compared using the Fisher′ s exact test. Results:A total of 303 cortical tubers were explored using SEEG in 50 patients.The tubers were divided into 6 types, including Type A, B, C, D and E, and focal cortical dysplasia like (FCD-like) type, among which Type E was for the first time proposed in the world.Among these explored tubers, 7 tubers had electrical seizures, and 57 tubers had electroclinical seizures.A total of 64 tubers (21.1%) were epileptogenic.The incidence of epileptogenic tubers in Type A-E and FCD-like type were 3.6%, 1.4%, 19.0%, 77.8%, 77.5%, and 90.0%, respectively. Fisher′ s exact test and Bonferroni correction were performed for pairwise comparisons( P<0.003). There was no significant difference in the incidence of epileptogenic tubes among Type A, B and C. There was significant difference in the incidence of epileptogenic tubes between Type A-C with Type D, Type E and FCD-like type, respectively.There was no significant difference in the incidence of epileptogenic tubes between Type D, Type E and FCD-like like.Electrical stimulation-induced seizures occurred in 36 cortical tubers (11.9%). The positive rate of electrical stimulation seizures in Type A-E and FCD-like type were 0.7%, 1.4%, 4.8%, 44.4%, 45.0%, and 70.0%, respectively.There was significant difference in the positive rate of electrical stimulation seizures between Type A-B and Type D, Type E and FCD-like type, respectively, so as that between Type C versus Type E and FCD-like type.No significant difference in the positive rate of electrical stimulation seizures was found between other pairwise comparisons. Conclusions:This study proposed a new classification of cortical tubers in TSC patients, and Type E is proposed for the first time in the world.SEEG records confirmed great differences in epileptogenicity indifferent types of cortical tubers.Type D, Type E and FCD-like type have higher epileptogenicity, which is of great value for the preoperative evaluation of TSC epilepsy surgery and the placement strategy of SEEG electrodes.

Objective:To observe the clinical and multimodal imaging features of eyes with acute macular neuroretinopathy (AMN) associated with the coronavirus disease 2019 (COVID-19).Methods:A retrospective study. From December 20, 2022 to January 17, 2023, a total of 29 patients (58 eyes) with COVID-19-associated AMN admitted to Department of Ophthalmology of Eye and ENT Hospital, Shanghai Medical College were included in the study. All the affected eyes underwent the best corrected visual acuity, color fundus photography, infrared fundus photography (IR), short-wavelength autofluorescence (SW-AF), near-infrared autofluorescence (NIL-AF), optical coherence tomography (OCT), and OCT angiography (OCTA). All patients were administered microcirculation-improving oral medication with 12 cases receiving adjunctive low-dose corticosteroid therapy. Follow-ups were conducted 1 to 3 months after the initial diagnosis, with a total of 19 cases (38 eyes) completing the one-month follow-up.Results:Out of the 29 cases, there were 9 males (18 eyes) and 20 females (40 eyes), all of whom experienced bilateral eye involvement. The age of the patients ranged from 12 to 47 years, with an average age of (29.9±9.5) years. The time from the onset of fever to the appearance of ocular symptoms was (2.52±2.01) days. Among the 58 affected eyes, there were 5 cases with retinal cotton wool spots, 2 cases with optic disc edema, and 1 case with parafoveal branch retinal vein occlusion. All affected eyes exhibited deep reddish-brown macular dark spots. IR revealed wedge-shaped, wedge-like, or "petaloid-like" dark areas involving the fovea and parafovea. SW-AF examination showed no obvious abnormality in 39 eyes. Weak autofluorescence dark area were consistent with IR in 19 eyes. NIR-AF examination showed spot-like or flaky self-fluorescent dark areas. OCT examination showed strong reflex lesions spreading vertically upward from the retinal pigment epithelium (RPE) layer in the macular area in the acute stage, showing typical "bean seedling" sign. OCTA revealed reduced blood flow density in the deep capillary plexus (DCP) of 50 eyes. Enface OCT displayed lesion areas that corresponded to the dark areas seen in IR. One month after the initial diagnosis, the condition improved in 18 eyes (47.4%, 18/38). Among the 5 eyes with cotton wool spots, regression of these spots was accompanied by loss of nerve fiber layer in 4 eyes. In cases with optic disc edema, the edema subsided. The "bean sprout" sign disappeared in all affected eyes, and the lesions became localized. The ellipsoid zone and/or interdigitation zone in the lesion areas were discontinuous.Conclusions:COVID-19-related AMN is characterized by distinctive features. IR fundus reveals wedge-shaped, wedge-like, or petaloid dark areas involving the fovea and parafovea. OCT displays strongly reflective lesions with vertical spread above the RPE. OCTA shows reduced blood flow density in the DCP of the retina.

In recent years, the rapid increase in cancer treatment costs in China had brought a huge economic burden to society, and it was urgent to standardize the rational application of anti-tumor drugs. In the context of the reform of group payment related to disease diagnosis, a tertiary first-class hospital focused on the needs of patients and guided by value-based healthcare, established a professional and normalized refined anti-tumor drug management system, setted up a multidisciplinary diagnosis and treatment team, and promoted " Internet plus pharmaceutical services" in December 2018.From 2019 to 2021, the proportion of hospital drugs were 30.8%, 30.1%, and 27.3%, respectively. The amount of money spent on anti-tumor drugs were 83.25 million yuan, 76.41 million yuan, and 62.48 million yuan, respectively, showing a decreasing trend year by year. The practice of refined management of anti-tumor drugs fully reflected the core concept of value based healthcare, achieving closed-loop management of the entire process of drugs, improving the level of rational drug use, reducing the economic burden on patients, and providing reference for improving the level of rational use of anti-tumor drugs in public hospitals.
