Atherosclerosis(AS)is a chronic inflammatory disease of large and medium-sized arteries that leads to ischemic heart disease,stroke,and peripheral vascular disease.Despite the current treatments,mortality and disability still remain high.Sonodynamic therapy(SDT),a non-invasive and localized methodology,has been developed as a promising new treatment for inhibiting atherosclerotic progression and sta-bilizing plaques.Promising progress has been made through cell and animal assays,as well as clinical trials.For example,the effect of SDT on apoptosis and autophagy of cells in AS,especially macrophages,and the concept of non-lethal SDT has also been proposed.In this review,we summarize the ultrasonic parameters and known sonosensitizers utilized in SDT for AS;we elaborate on SDTs therapeutic effects and mechanisms in terms of macrophages,T lymphocytes,neovascularization,smooth muscle cells,lipid,extracellular matrix and efferocytosis within plaques;additionally,we discuss the safety of SDT.A comprehensive summary of the confirmed effects of SDT on AS is conducted to establish a framework for future researchers.

Objective:To quantitatively evaluate the changes of choroidal biomarkers in patients with central serous chorioretinopathy (CSC) and preliminarily explore its pathogenesis.Methods:Clinical cross-sectional study. From July 2021 to December 2022, 74 eyes of 65 patients with CSC (CSC group) confirmed by ophthalmic examination at the First Affiliated Hospital of Zhengzhou University were included in the study. Among them, 46 patients (51 eyes) were male, 19 patients (23 eyes) were female. The duration from the onset of symptoms to the time of treatment was less than or equal to 3 months. A control group consisted of 40 healthy volunteers (74 eyes) matched in age and gender. Among them, 26 patients (50 eyes) were male, and 14 patients (24 eyes) were female. Using VG200D from Microimaging (Henan) Technology Co., Ltd., macular scanning source light coherence tomography angiography was performed, with scanning range 6 mm × 6 mm. According to the division of the diabetes retinopathy treatment research group, the choroid within 6 mm of the macular fovea was divided into three concentric circles centered on the macular fovea, namely, the central area with a diameter of 1 mm, the macular area with a diameter of 1-3 mm, and the surrounding area of the fovea with a diameter of 3-6 mm. The device comes with software to record the three-dimensional choroidal vascular index (CVI), choroidal vascular volume (CVV), perfusion area of the choroidal capillary layer (CFA), choroidal thickness (CT), and three-dimensional CVI, CVV, and CT in the upper, temporal, lower, and subnasal quadrants within 6 mm of the fovea. Quantitative data between the two groups were compared using an independent sample t-test. Qualitative data comparison line χ2 inspection. The value of receiver operating curve (ROC) analysis in predicting the occurrence of CSC, including CVI, CVV, CFA, and CT. Results:Compared with the control group, the CVI ( t=3.133, 4.814), CVV ( t=7.504, 9.248), and CT ( t=10.557, 10.760) in the central and macular regions of the affected eyes in the CSC group significantly increased, while the CFA ( t=-8.206, -5.065) significantly decreased, with statistically significant differences ( P<0.05); CVI ( t=7.129), CVV ( t=10.020), and CT ( t=10.488) significantly increased within 6 mm of the central fovea, while CFA ( t=-2.548) significantly decreased, with statistically significant differences ( P<0.05). The CVI ( t=4.980, 4.201, 4.716, 8.491), CVV ( t=9.014, 7.156, 7.719, 10.730), and CT ( t=10.077, 8.700, 8.960, 11.704) in the upper, temporal, lower, and lower nasal quadrants within 6 mm of the central fovea were significantly increased, with statistically significant differences ( P<0.05). In the CSC group, the maximum CVI and CVV were (0.39±0.10)% and (1.09±0.42) mm 3, respectively, on the nasal side of the affected eye. Upper CT was (476.02±100.89) μm. The nasal side CVI, CVV, and CT have the largest changes. The ROC curve analysis results showed that the area under the curve of CT, CVV, and CVI within 6 mm of the central region, macular region, and fovea was over than 0.5. Subcentral CT was the most specific for the diagnosis of CSC. Conclusion:Choroidal biomarkers CVI, CVV, and CT in CSC patients increase, while CFA decreases. Central CT is the most specific for the diagnosis of CSC.

Objective:To observe the anastomotic status of the vortex veins in patients with central serous chorioretinopathy (CSC).Methods:A cross-sectional study of clinical practice. From July 2021 to July 2022, 50 cases (50 eyes) of monocular CSC patients diagnosed through ophthalmic examination at the First Affiliated Hospital of Zhengzhou University were included in the study. Among them, there were 37 males (74.0%, 37/50) and 13 females (26.0%, 13/50), with the mean age of (44.30±9.59) years old. The course of disease from the onset of symptoms to the time of treatment was less than 3 months. The affected eye and contralateral eye of CSC patients were divided into the affected eye group and contralateral eye group, respectively. Fifty healthy volunteers of the same age and gender were selected as the normal control group with 50 eyes. The macular area scanning source optical coherence tomography (OCT) vascular imaging examination was performed with Visual Microimaging (Henan) Technology Co., Ltd. VG200D. Horizontal watershed vortex veins anastomosis rate and asymmetric vortex-venous dilation rate were observed by en face OCT. The device comes with software to calculate the central foveal choroidal thickness (SFCT), mean choroidal thickness (MCT), and choroidal vascular index (CVI). One-way analysis of variance and χ2 test were used to compare the three groups. When variances were unequal between groups, nonparametric tests were performed. Results:The SFCT values of the affected eye group, contralateral eye group, and normal control group were (567.12±129.02), (513.26±133.17), (327.64±97.40) μm, respectively; MCT were (407.38±97.54), (388.24±94.13), (275.46±60.55) μm, respectively; CVI were 0.34±0.05, 0.32±0.04, and 0.27±0.04, respectively; anastomosis rates of vortex veins were 98% (49/50), 78% (39/50), and 40% (20/50), respectively; asymmetric dilation rates of vortex veins were 96% (48/50), 88% (44/50), and 48% (24/50), respectively. The differences of SFCT ( F=53.974), MCT ( Z=51.415), CVI ( F=28.082), vortex vein anastomosis rate ( χ2=43.056), asymmetric dilation rate of vortex veins ( χ2=37.728) among three groups were statistically significant ( P<0.001). Compared with the contralateral eye group, the SFCT, MCT, CVI, vortex vein anastomosis rate, and vortex vein asymmetric dilation rate in the affected eye group were significantly higher than those in the contralateral eye group. Among them, the differences of SFCT ( t=2.054), CVI ( t=2.211), and vortex vein anastomosis rate ( χ2=9.470) were statistically significant ( P<0.05); the differences of MCT ( Z=7.490), asymmetric dilation rate of vortex veins ( χ2=2.714) were not statistically significant ( P=1.000, 0.140). Conclusions:SFCT, MCT, and CVI in the affected and contralateral eyes of monocular CSC patients significantly increase. The anastomotic rate and asymmetric dilation rate of the vortex vein in the opposite eye were lower than those in the affected eye.

In recent years, the development of bispecific antibodies (bsAbs) has been rapid, with many new structures and target combinations being created. The boom in bsAbs has led to the successive issuance of industry guidance for their development in the US and China. However, there is a high degree of similarity in target selection, which could affect the development of diversity in bsAbs. This review presents a classification of various bsAbs for cancer therapy based on structure and target selection and examines the advantages of bsAbs over monoclonal antibodies (mAbs). Through database research, we have identified the preferences of available bsAbs combinations, suggesting rational target selection options and warning of potential wastage of medical resources. We have also compared the US and Chinese guidelines for bsAbs in order to provide a reference for their development.

Trauma registration is an important tool to record the process and timeline in the treatment of trauma patients. The operation of trauma database is of great significance for reducing the mortality of patients, promoting the construction of trauma treatment system, and providing reference for policy-making. Trauma registration system has been established in the United States, United Kingdom, Germany and other developed countries for many years. However, the domestic system is still at an initial stage, and there are problems like data deficiencies, data incoherence, no item of complications, no treatment data after discharge and limits of human and financial resources. Therefore, there is room for improvements in terms of personnel fixation, financial support and continuous data monitoring should be further improved. In this study, the authors summarize the traum registration system from aspects of basic situation both at home and abroad, data analysis, clinical value, operation mechanism and challenges so as to provide important data for clinical researches.

Objective To investigate the clinical features and prognosis of HIV-negative plasmablastic lymphoma (PBL) patients. Methods We collected HIV-negative PBL cases reported in our hospital and other literatures from online databases from January 1, 1997 to March 30, 2020. The data of clinical features, molecular pathology, treatment and prognosis were summarized and analyzed. Results We included 60 PBL patients, average age was 53.06±14.36 years, and most of them had relatively high Ann Arbor stage and Ki-67 expression. The average OS was 13.48±13.21 m. Kaplan-Meier curve revealed Ann Arbor stage, IPI index (3-5), B symptoms and CR in initial treatment were significantly related with patients' survival. Cox regression analysis indicated that the Ann Arbor stage and IPI index were the independent prognostic factors for patients' survival. Conclusion HIV-negative PBL mostly occurs in the middle-age and elderly patients, with advanced diagnosis stage and rapid tumor proliferation. Combination chemotherapy is the main treatment, while the therapeutic response and OS might be heterogeneous, the prognosis of most patients would be poor. The stage and IPI index are significantly related to the prognosis.

Objective:To compare the consistency in diagnosing and staging acute kidney injury (AKI) in children with chronic kidney disease (CKD) according to three criterias.Methods:Children with CKD hospitalized in the First Affiliated Hospital of Sun Yat sen University from January 2013 to December 2019 were analyzed retrospectively. These patients underwent serum creatinine examination more than twice during hospitalization. The AKI diagnosis and staging were performed for each patient according to the 2007 pRIFLE, 2012 KDIGO and 2018 pROCK criteria respectively. All the children were followed up for 1 year after discharge through outpatient visit, re-hospitalization or online consultation. The clinical characteristics and prognosis of CKD children with or without AKI that were diagnosed by 3 criteria were compared. Analysis of variance and chi-squared tests were used for the comparison among groups. Concordance between the different diagnostic criteria was evaluated using Cohen′s kappa coefficient.Result:A total of 2 551 children with CKD were included in this study, with an age of (8±4) years. There were 1 628 boys and 923 girls. Nephrotic syndrome was the most prevalent primary disease (55.4%), followed by lupus nephritis (11.2%) and purpura nephritis (8.2%). Among all stages of CKD, CKD category G1 was the most common type (2 146 cases, 84.1%), followed by CKD category G2 (221 cases, 8.7%). AKI occurence rates according to pRIFLE, KDIGO and pROCK criteria were 33.9% (866/2 551), 26.2%(669/2 551) and 19.5% (498/2 551) respectively (χ2=136.3, P<0.01). The diagnostic consistency within three criteria for AKI was high in children with CKD ( κ=0.702), but AKI staging consistency was low ( κ=0.329). Both the diagnosis and staging consistency of three AKI criteria were poor in children with CKD category G5 (all κ<0.400). The length of hospital stay (LOS), hospitalization costs, the occurence of intensive care unit (ICU) admission and in-hospital mortality were significantly higher in children with AKI diagnosed by different criteria ( P<0.05). After 1-year follow-up, the repeated admission rate and CKD staging progress significantly increased in children with AKI ( P<0.05). In children with baseline serum creatinine≥200 μmol/L, compared with children who did not experience AKI during hospitalization, the LOS and the hospitalization costs in children who were diagnosed AKI according to pRIFLE or pROCK criteria was significantly higher ( P<0.05). However, there was no significant difference in the LOS and hospitalization costs between children with or without AKI who were diagnosed according to KDIGO criteria (all P>0.05). Conclusions:AKI diagnosed by all of the three criteria (pRIFLE, KDIGO and pROCK criteria) was associated with the poor prognosis in children with CKD. However, in those whose baseline serum creatinine≥ 200 μmol/L, AKI diagnosed by pRIFLE and pROCK criteria could better reflect the poor outcomes than by KDIGO criteria.

Dysregulation of the gut microbiota/gut hormone axis contributes to the pathogenesis of irritable bowel syndrome (IBS). Melatonin plays a beneficial role in gut motility and immunity. However, altered expression of local mucosal melatonin in IBS and its relationship with the gut microbiota remain unclear. Therefore, we aimed to detect the colonic melatonin levels and microbiota profiles in patients with diarrhea-predominant IBS (IBS-D) and explore their relationship in germ-free (GF) rats and BON-1 cel s. Thirty-two IBS-D patients and twenty-eight healthy controls (HCs) were recruited. Fecal specimens from IBS-D patients and HCs were separately transplanted into GF rats by gavage. The levels of colon mucosal melatonin were assessed by immunohistochemical methods, and fecal microbiota communities were ana-lyzed using 16S rDNA sequencing. The effect of butyrate on melatonin synthesis in BON-1 cel s was eval-uated by ELISA. Melatonin levels were significantly increased and negatively correlated with visceral hypersensitivity in IBS-D patients. GF rats inoculated with fecal microbiota from IBS-D patients had high colonic melatonin levels. Butyrate-producing Clostridium cluster XIVa species, such as Roseburia species and Lachnospira species, were positively related to colonic mucosal melatonin expression. Butyrate signif-icantly increased melatonin secretion in BON-1 cel s. Increased melatonin expression may be an adaptive protective mechanism in the development of IBS-D. Moreover, some Clostridium cluster XIVa species could increase melatonin expression via butyrate production. Modulation of the gut hormone/gut micro-biota axis offers a promising target of interest for IBS in the future.

Objective:To translate the Incontinence-Associated Dermatitis Intervention Tool (IADIT) into Chinese and to test the reliability and validity.Methods:The IADIT was translated into Chinese after getting the approval of original author, professor Junkin. We selected 15 experts with a high academic in incontinence nursing and rich clinical experience for two rounds of consultation to determine the Chinese version and its validity. At the time, the reliability of the Chinese version of IADIT was tested at a ClassⅢ Grade A hospital.Results:The item-content validity index ( I- CVI) of the Chinese version of IADIT ranged from 0.80 to 1.00, and the scale-content validity index ( S- CVI) of the tool was 0.98. The reliability of assessors was r=0.928 ( P<0.01) , and the test-retest reliability was 0.996 ( P<0.01) . Conclusions:The Chinese version of the IADIT has a good reliability and validity which could guide nurses to carry out assessment and intervention for incontinence patients.

Objective: To understand the intention of pediatricians turnover in Shenzhen and its influencing factors. Methods: From September to December 2016, a multi-stage stratified cluster sampling method was used to select 948 pediatricians from Shenzhen to conduct a questionnaire survey. The questionnaire cover the following: 1. Basic information: general demographic characteristics(gender, age, marriage, education, etc.); 2. Work status survey: turnover intention, experiences with violence against medical workers, professional job satisfaction, and work stress, etc. Univariate analysis and multivariate analysis were used to identify factors for pediatrician′s turnover intention. Results: Among the 948 pediatricians in Shenzhen, 62.5% had turnover intention; age, title, education, seniority, monthly income, medical institution nature, medical institution level, length of sleep, job satisfaction, work stress, experience with violence and family support all affect the pediatrician′s turnover intention(P<0.05); multivariate logistic regression analysis showed that age, education, monthly income, job satisfaction, work stress and experience with violence were the influencing factors of pediatrician′s turnover intention(P<0.05). Conclusions The pediatrician′s turnover intention in Shenzhen is not low. Relevant measures should be taken by the government, hospital administrators, children patients and their family to ensure the supply of children′s medical services.
