Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

Objective:To explore the effect of staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair.Methods:From January 2021 to December 2022, convenience sampling was used to select 73 patients who underwent arthroscopic rotator cuff repair in the Department of Hand Surgery at Affiliated Hospital of Nantong University as participants. According to the random number table method, patients were divided into a control group ( n=36) and an observation group ( n=37). Control group received routine rehabilitation nursing, while observation group received staged rehabilitation nursing. The University of California, Los Angeles (UCLA) Shoulder Rating Scale score, American Shoulder and Elbow Surgeons (ASES) Rating Scale score, Constant-Murley Shoulder Scale score, and complications during rehabilitation were compared between two groups of patients before and six months after intervention. Results:Six months after surgery, both groups showed an increase in UCLA scores and ASES scores compared to before the intervention ( P<0.05), and the scores of observation group were higher than those of control group, with statistical differences ( P<0.05). Six months after surgery, the Constant-Murley Shoulder Scale scores for daily life and shoulder range of motion in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05). During the rehabilitation period, the incidence of complications in observation group was lower than that in control group with a statistical difference ( P<0.05) . Conclusions:Staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair shows significant effects and can effectively promote patient recovery.

Objective:To investigate the clinical characteristics and prognosis of Epstein-Barr virus-related diseases in adults.Methods:The clinical data of 59 patients with Epstein-Barr virus-related diseases in Huashan Hospital, Fudan University, Shanghai from January 2017 to August 2019 were analyzed retrospectively. The clinical manifestations of patients with infectious mononucleosis (IM), chronic active Epstein-Barr virus infection (CAEBV) and lymphoma in patients were compared. Patients were divided into acute course group (IM) and chronic course group (CAEBV+ lymphoma), and the results of labratory indications (blood rontine, liver function, imflammatory indications, Epstein-Barr virus DNA, Epstein-Barr virus antibody and T lymphocyte) were compared between two groups. Statistical analysis was performed by Mann-Whitney U test, chi-square test or Fisher exact probability test. Results:Among the 59 patients, 23 cases (39.0%) were diagnosed with IM, 23 cases (39.0%) were lymphoma and 13 cases (22.0%) were CAEBV. The clinical manifestations of patients with Epstein-Barr virus-related diseases were fever (57/59, 96.6%), lymphadenopathy (37/59, 62.7%) and splenomegaly (36/59, 61.0%). There were 17 patients in the chronic course group experienced hemophagocytic lymphohistiocytosis (HLH). The white blood cell counts, hemoglobin levels and platelet counts of patients in the chronic course group (4.07(1.94, 8.35)×10 9/L, 89.5(74.5, 108.0) g/L and 100(37, 161)×10 9/L, respectively) were all lower than those in the acute course group (9.91(6.75, 17.38)×10 9/L, 132.5(118.2, 152.0) g/L and 197(129, 233)×10 9/L, respectively), with statistically significant differences ( U=3.69, 5.22 and 3.61, respectively, all P<0.01). The levels of procalcitonin, C-reactive protein and serum ferritin in the chronic course group (0.45(0.15, 1.13) μg/L, 47.75(17.57, 84.67) mg/L and 2 000(682, 2 002) μg/L, respectively) were all higher than those in the acute course group (0.12(0.07, 0.28) μg/L, 6.39(3.13, 11.38) mg/L and 482(159, 1 271) μg/L, respectively), with statistically significant differences ( U=-2.95, -3.77 and -4.16, respectively, all P<0.01). The counts of CD4 + T lymphocytes, CD8 + T lymphocytes, CD19 + B lymphocytes and natural killer cells in the chronic course group (259.15(101.98, 509.26), 214.69(119.31, 529.47), 46.14(4.44, 135.87) and 81.09(41.53, 118.46)/μL, respectively) were all lower than those in the acute course group (738.88(592.20, 893.94), 1 609.17(920.88, 3 952.34), 144.52(83.65, 215.14) and 309.82(123.78, 590.68)/μL, respectively), with statistically significant differences ( U=3.66, 3.80, 2.90 and 3.40, respectively, all P<0.01), while the CD4 + /CD8 + T lymphocytes ratio in the chronic course group was higher (0.90(0.60, 1.70) vs 0.45(0.10, 1.28))( U=-2.29, P=0.02). Twenty-three patients with IM were all cured, while 10 patients with lymphoma died and 13 received chemotherapy. Seven patients with CAEBV died and six improved. Conclusions:The clinical characteristics of Epstein-Barr virus-related diseases in adults are fever, lymphadenectasis, splenomegaly.Chronic Epstein-Barr virus infection may be associated with HLH. The prognosis of adults with acute Epstein-Barr virus infection is good, while that of long-term chronic Epstein-Barr virus infection is poor.

Recent clinical studies have found that there are still a large number of patients who do not respond to immune checkpoint inhibitors (ICIs). Improving immunotherapy response in ccRCC patients is an urgent clinical need. Targeting different components of the tumor immune microenvironment becomes a breakthrough point for overcoming the immunotherapy resistance and optimizing therapeutic strategies in advanced ccRCC. Several novel immunotherapeutic strategies are currently under clinical investigation, including targeting other co-inhibitory and co-stimulatory molecules, modified cytokine therapies, small-molecule immunomodulators, targeting immune metabolism, and cancer vaccines, each of which target different immunomodulatory pathways in the tumor immune microenvironment for the treatment of ccRCC. In this paper, we provide an overview of the current challenges faced by immunotherapy for advanced ccRCC and review novel immunotherapy strategies based on the tumor immune microenvironment.

Objective:To evaluate facial asymmetry among Chinese young population via three-dimensional photogrammetry.Methods:Young subjects were recruited in Beijing from May to December in 2017. Three-dimensional facial images were obtained by VECTRA H1 camera. The images were exported to Geomagic Wrap 2017. Soft tissue landmarks were identified, and a coordinate system was built on every image. The face was divided into upper, middle, and lower part by the horizontal plane passing the exocanthion and the horizontal plane passing the cheilion. On the coronal plane, the distances between the midsagittal plane and the homogeneous landmarks located on the right and left hemifaces as well as bilateral palpebral fissure height were computed. In terms of facial depth, facial depth parameters located on the right and the left hemifaces were computed. There was a total of 13 parameters. Parameters on one hemiface were compared with those on the other hemiface using paired t-test. Mean absolute difference (MAD) and asymmetric rate (AR) were computed. Finally, we compared the result on men to the result on women via t-test. P<0.05 was considered statistically significant. Results:There was a total of 122 young subjects, 60 men (25.1±3.8 years old) and 62 women (27.3±4.3 years old). (1) On coronal plane, among males, the difference between bilateral tragion and midsagittal plane and the difference between bilateral cheilion and midsagittal plane were statistically significant( P<0.05); among females, the difference between bilateral exocanthion and midsagittal plane, the difference between bilateral palpebrale superius and midsagittal plane, and the difference between bilateral tragion and midsagittal plane were statistically significant ( P<0.05). Among bilateral landmarks (except for palpebral fissure height), the MAD of the distance between bilateral exocanthion and midsagittal plane was the smallest, (1.00±0.88) mm (AR=2.1%) and (1.08±0.79) mm (AR=2.4%) among men and women, respectively ( t=0.541, P=0.589). The MAD of the distance between lateral tragion and midsagittal plane was the largest, (3.45±2.54) mm (AR=4.6%) and (2.89±2.86) mm (AR=4.1%) among men and women, respectively ( t=-1.149, P=0.253). (2) In terms of facial depth, among both males and females, the difference between all bilateral facial depth parameters was statistically significant ( P<0.05). The MAD of the distance between the pogonion and bilateral tragion was the largest, (2.62±1.69) mm (AR=1.8%) and (2.45±1.69) mm (AR=1.8%) among men and women, respectively ( t=-0.491, P=0.625); the MAD of the distance between the glabella and bilateral tragion was the smallest, (1.77±1.25) mm (AR=1.4%) and (1.91±1.54) mm (AR=1.6%) among men and women, respectively ( t=0.587, P=0.558). Conclusions:Facial asymmetry is universal among Chinese young population. The MAD does not exceed 3.5 mm. Upper one-third face has higher symmetry while lower one-third face has lower symmetry.
