ObjectiveTo evaluate the measles surveillance system （MSS） in Jiading District， Shanghai from 2020 to 2022， and to provide evidence for the elimination of measles. MethodsDescriptive methods were used to analyze the MSS data and confirmed measles cases from 2020 to 2022 and to evaluate MSS performance indicators. ResultsA total of 120 suspected cases were reported through the MSS from 2020 to 2022， of which 12 were classified as measles， 9 as rubella， and 99 as non-measles /rubella. The incidence of reported non-measles /rubella was 1.44 per 100 000 population in 2020， 2.01 per 100 000 population in 2021， and 1.99 per 100 000 population in 2022. The rates of complete investigation within 48 hours， blood samples and etiology collection， timely delivery， and timely reporting were all 100%. Among the 12 confirmed measles cases from 2020 to 2022， seven routine immunization subjects completed the required doses of measles vaccines， while two out five adult cases had a history of measles vaccine-related immunization. The confirmed cases comprised six with fever accompanied by rash， five with rash alone， and one with fever alone. ConclusionThe MSS results in Jiading District， Shanghai are overall satisfactory. However， there is a need to improve sensitivity， especially in detecting and reporting cases with atypical symptoms. It is imperative to maintain high vaccination coverage for age-appropriate children， promote supplementary immunization activities， and elevate the overall immunity of the entire population.

As the search for effective treatments for COVID-19 continues, the high mortality rate among critically ill patients in Intensive Care Units (ICU) presents a profound challenge. This study explores the potential benefits of traditional Chinese medicine (TCM) as a supplementary treatment for severe COVID-19. A total of 110 critically ill COVID-19 patients at the Intensive Care Unit (ICU) of Vulcan Hill Hospital between Feb., 2020, and April, 2020 (Wuhan, China) participated in this observational study. All patients received standard supportive care protocols, with a subset of 81 also receiving TCM as an adjunct treatment. Clinical characteristics during the treatment period and the clinical outcome of each patient were closely monitored and analysed. Our findings indicated that the TCM group exhibited a significantly lower mortality rate compared with the non-TCM group (16 of 81 vs 24 of 29; 0.3 vs 2.3 person/month). In the adjusted Cox proportional hazards models, TCM treatment was associated with improved survival odds (P < 0.001). Furthermore, the analysis also revealed that TCM treatment could partially mitigate inflammatory responses, as evidenced by the reduced levels of proinflammatory cytokines, and contribute to the recovery of multiple organic functions, thereby potentially increasing the survival rate of critically ill COVID-19 patients.

Tendinopathies are chronic diseases of an unknown etiology and associated with inflammation. Mesenchymal stem cells (MSCs) have emerged as a viable therapeutic option to combat the pathological progression of tendinopathies, not only because of their potential for multidirectional differentiation and self-renewal, but also their excellent immunomodulatory properties. The immunomodulatory effects of MSCs are increasingly being recognized as playing a crucial role in the treatment of tendinopathies, with MSCs being pivotal in regulating the inflammatory microenvironment by modulating the immune response, ultimately contributing to improved tissue repair. This review will discuss the current knowledge regarding the application of MSCs in tendinopathy treatments through the modulation of the immune response.

ObjectiveTo observe the effectiveness and safety of Qihuang Yishen Granules （芪黄益肾颗粒） combined with traditional Chinese medicine （TCM） chronic disease management on patients with diabetic kidney disease with deficiency qi and yin. MethodsTotally 140 patients diagnosed as diabetic kidney diseases with deficiency of both qi and yin were randomly divided into control group and trial group，with 70 cases in each group. Patients in the control group were treated with symptomatic treatment and routine chronic disease management. Patients in the trial group added Qihuang Yishen Granules and chronic disease management with TCM characteristics on the basis of symptomatic treatment. The course of treatment in both groups lasted for 6 months. The changes of laboratory indexes and chronic disease management level scores of the two groups of patients before treatment and after 3 and 6 months of treatment were compared， and their correlation were analyzed.The laboratory indexes of urinary protein and renal function related indicators such as 24-hour urinary protein quantification （24 hUTP）， serum creatinine （Scr）， blood urea nitrogen （BUN）， and estimated glomerular filtration rate （eGFR）， and control compliance rate， as well as blood glucose and lipid related indicators such as glycosylated hemoglobin （HbA1c）， low-density lipoprotein cholesterol （LDL-C）， triglyceride （TG） and control compliance rate were observed. The chronic disease management level scores included exercise，cognitive symptom management practice，communication with doctors， self-efficacy of symptom management，self-efficacy of disease commonness management. ResultsFinally，67 cases in the control group and 68 cases in the trial group completed the study. Compared with the group before treatment， the trial group had lower 24 hUTP and Scr， higher exercise score， total self-management score and all self-efficacy scale scores， higher TG at 3 months of treatment； at 6 months of treatment， the trial group had lower 24 hUTP， higher eGFR， and higher self-management scores and self-efficacy scale scores of all chronic diseases （P＜0.05）， and the control group had higher self-management total score （P＜0.05）. After 6 months of treatment， the trial group had lower 24 hUTP， Scr， LDL-C， and TG， higher eGFR， higher compliance rate of 24 hUTP， eGFR， LDL-C， and TG， and higher scores for all chronic disease management indexes compared with the control group （P＜0.05）. In terms of the correlation between laboratory indicators and chronic disease management level scores：there was a statistically significant difference in the correlation between 24hUTP and exercise，symptom management self-efficacy，and self-efficacy of disease commonness management （P＜0.05 or P＜0.01），all of which were negatively correlated. There was a statistically significant difference in the correlation between Scr and symptom management self-efficacy and self-efficacy of disease commonness management （P＜0.01），both of which were negatively correlated. There was a statistically significant difference in the correlation between eGFR and symptom management self-efficacy and self-efficacy of disease commonness management （P＜0.01），both of which were positively correlated. ConclusionQihuang Yishen Granules combined with chronic disease management of TCM can improve the level of proteinuria，renal function and lipid metabolism in patients with diabetic kidney disease with deficiency of both qi and yin，thus delaying the progress of diabetic kidney disease and also improve the level of chronic disease management of patients.

ObjectiveTo analyze the research hotspots and development trends of postpartum rehabilitation at home and abroad in the past ten years. MethodsCiteSpace 6.2.R2 was used to analyze the co-occurrence, cluster, and bursting of keywords of the relevant literature in the field of postpartum rehabilitation in CNKI and Web of Science (WOS) in the past ten years. ResultsTotally, 2 686 Chinese papaers were included in CNKI and 1 247 English papers were included in WOS. Both databases showed an increasing trend in the number of publications related to the field of postpartum rehabilitation, but the overall number of publications in CNKI grew faster and the total number of publications was more than that in WOS. For CNKI, there were 455 nodes, 1 102 links, with a density of 0.010 7; nine clusters were obtained; the bursting keywords showed that the diseases of concern shifted from breast distension and pain to pelvic floor diseases, and the hot spots of treatment methods shifted from Chinese medicine to electrical stimulation, biofeedback, and then pelvic floor training. For WOS, there were 463 nodes, 1 633 connected lines, with a density of 0.015 3; 14 clusters were obtained; the bursting keywords showed that the disease hotspots of concern shifted from anal prolapse and postpartum hemorrhage to organ prolapse, the hotspots of treatment methods shifted from analgesia to exercise, and the focus of research methods shifted from trial to qualitative research and meta-analysis. ConclusionDomestic postpartum rehabilitation started later than foreign countries. Although certain research results have been achieved, there is still a certain gap compared with the development of foreign postpartum rehabilitation.

Objective:To evaluate the application of three-dimensional (3D) imaging device to colonoscopy.Methods:A total of 60 patients who underwent painless colonoscopy in Beijing Friendship Hospital, Capital Medical University from November to December, 2019 were enrolled and divided into 2 groups according to random code. Each patient underwent colonoscopy twice, while 2D colonoscopy was used for cecal intubation. Thirty patients were assigned to the experimental group (primary withdrawal used 3D colonoscopy, and secondary withdrawal used 2D colonoscopy), and 30 others to the control group (primary withdrawal used 2D colonoscopy, and secondary withdrawal used 3D colonoscopy). The detection of polyps, the withdrawal time, operating experience, image quality and complication were evaluated in the two groups.Results:The polyp detection rate at the first colonoscopy in the experimental group was 77.3% (17/22), which was higher than 43.5% (10/23) in the control group ( χ2=5.351, P=0.021). Ten operators in the experimental group had dizziness, while the operators in the control group had no dizziness ( P=0.001). There were no significant differences between the two groups in the polyp diameter [0.50 (0.70) cm VS 0.30 (0.20) cm, U=57.000, P=0.170], withdrawal time (4.6±1.5 min VS 5.2±1.9 min, t=-1.189, P=0.239) or image quality (27 cases with 3 points in the identification of lesion nature, and 28 cases with 3 points in the identification of duct both in the two groups, P=1.000) at the first colonoscopy. No complication occurred in either group. Conclusion:Application of 3D imaging device is feasible for colonoscopic polyp detection, and it can be used in clinical practice.

Objective:To evaluate the extent and progression of coronary artery calcification in maintenance hemodialysis (MHD) patients, and to explore the risk factors of rapid progression of coronary artery calcification in MHD patients.Methods:The patients who underwent MHD in the Huashan Hospital affiliated to Fudan University from January 1, 2013 to December 31, 2017 were enrolled. This study included cross-sectional study and prospective cohort study. Multi-slice spiral computed tomography was used to measure coronary artery calcification, and coronary artery calcium score (CACS) was calculated. In the cross-sectional study, 62 MHD patients were enrolled. According to baseline CACS, the patients were divided into low calcification group (CACS < 100) and high calcification group (CACS ≥ 100). The nutritional and bone mineral metabolism indexes were compared between the two groups. Multiple linear regression analysis was used to analyze the correlation between CACS and muscle mass and laboratory indicators. Since 6 patients were lost to follow-up, 56 MHD patients who were followed-up regularly were enrolled in the prospective cohort study. According to the progression of CACS, the patients were divided into slow progression group (ΔCACS/year < 100) and rapid progression group (ΔCACS/year ≥ 100). Logistic regression equation was used to analyze the risk factors of coronary calcification progression. Hosmer-Lemeshow goodness of fit test and receiver operating characteristic curve were used to evaluate the performance of multivariate logistic regression model.Results:In the cross-sectional study, the age of 62 patients was (62.34±10.82) years old, and the median dialysis age was 78 (39,139) months. Among the 33 male patients, compared with the low calcification group ( n=7), the high calcification group ( n=26) had older age ( t=-2.281, P=0.030) and higher blood triglyceride ( Z=-1.985, P=0.047), and there was no statistically significant difference in muscle mass between the two groups; among the 29 female patients, the muscle mass/height 2 ( t=-2.600, P=0.015) and serum calcium ( t=-2.641, P=0.014) in the high calcification group ( n=15) were both higher than those in the low calcification group ( n=14), and the hemoglobin level was lower ( t=2.531, P=0.018), and the difference in muscle mass between the two groups was not statistically significant. High sensitivity C-reactive protein ( β=0.425, P=0.022) was independently correlated with CACS in male patients, and muscle mass/extracellular water ( β=-0.580, P=0.001) was independently correlated with CACS in female patients. In the prospective cohort study, the age of 56 patients was (59.82±11.14) years old, and the median dialysis age was 82 (40, 146) months. There was no significant difference in all-cause mortality between slow progression group ( n=22) and rapid progression group ( n=34), but the proportion of cardiovascular events in rapid progression group was significantly higher than that in slow progression group ( P=0.017). Compared with the slow progression group, the rapid progression group had higher proportion of males ( χ2=4.791, P=0.029), older age ( Z=-2.131, P=0.038), lower baseline muscle mass/extracellular water ( Z=2.482, P=0.016) and high-density lipoprotein cholesterol ( t=2.133, P=0.042), and faster rate of muscle mass loss (Δmuscle mass·height -2·year -1) ( Z=-2.282, P=0.023). Multivariate logistic regression analysis results showed that muscle mass loss ( OR=0.089, 95% CI 0.010-0.792, P=0.030) and baseline CACS ( OR=1.003, 95% CI 1.000-1.005, P=0.021) were influencing factors for progression of coronary artery calcification in MHD patients. Conclusion:Increasing baseline CACS and rapid reduction in muscle mass are risk factors for the progression of coronary artery calcification in MHD patients.

Objective:To analyze the correlation between cognitive impairment and cortical atrophy in elderly patients with asymptomatic carotid artery stenosis (ACAS).Methods:In this cross-sectional study, 40 consecutive elderly patients with ACAS treated in the Department of Neurology, Northern Jiangsu People′s Hospital from July 1, 2020 to June 30, 2021 (ACAS group), and 40 elderly healthy controls who accepted physical examination during the same period (control group) were included. Cognitive assessment was performed using the Mental State Examination Scale (MMSE) and the Montreal Cognitive Assessment Scale (MoCA), and brain magnetic resonance imaging scanning was performed in the ACAS group. The artificial intelligence technique was applied for brain lobe segmentation and cortical volume calculation. The χ2-test, independent sample t-test and Wilcoxon non-parametric test were used to analyze the difference of clinical data and cognitive scores between the two groups. In the ACAS group, the cortical volumes of the side with carotid stenosis was compared with that of the normal side, and Spearman′s correlation analysis was used to assess the correlation between cognitive scores and cortical atrophy. Results:Compared with the control group, the ACAS group got significantly lower scores of MMSE and MoCA, as well as lower scores of visuospatial executive function, attention and calculation, language function, abstraction ability and delayed recall [(25.60±2.49) vs (27.18±1.01), (22.05±3.59) vs (25.60±1.43), (2.73±1.04) vs (4.08±0.62), (4.53±0.93) vs (5.03±0.66), 2.00 (0.00) vs 3.00 (0.00), 1.00 (1.00) vs 2.00 (0.00), and (2.95±0.96) vs (3.35±0.62)] (all P<0.05). There was not significant differences in naming and orientation ability between the two groups (both P>0.05). The volume of cortical, temporal lobe, frontal lobe, parietal lobe and insular lobe on the side with carotid stenosis in the ACAS group were significantly smaller than those on the normal side [186.23 (177.97, 202.53) vs 194.67 (185.65, 204.82) cm 3, 54.74 (50.66, 56.95) vs 55.61 (51.24, 58.49) cm 3, 72.98 (70.76, 78.34) vs 75.27 (72.34, 80.66) cm 3, 53.66 (51.11, 57.86) vs 56.59 (52.80, 60.09) cm 3, 6.57 (6.35, 7.07) vs 6.72 (6.46, 7.34) cm 3] (all P<0.05). The MoCA score in the ACAS group was positively related to the cortical volume ratio of the two sides ( r=0.427, P<0.01). The attention ( r=0.353) and abstraction ( r=0.226) ability scores were positively correlated with the temporal lobe volume ratios of the two sides (both P<0.05). The visuospatial executive ( r=0.187) and language ( r=0.373) ability scores were positively correlated with frontal lobe volume ratios of the two sides (both P<0.05), and visuospatial executive ( r=0.386), naming ( r=0.344), language ( r=0.517), abstraction ( r=0.335) and delayed recall ( r=0.333) ability scores were positively correlated with parietal lobe volume ratios of the two sides (all P<0.05). Conclusion:In elderly patients with ACAS, the cognitive impairment and cortical atrophy on the sides with carotid stenosis are significant and a positive correlation is detected between them.

Objective:To evaluate the applicability of bone age (BA) assessment methods and to investigate the difference between BA and chronological age (CA) based on the data of children in rural areas of Beijing.Methods:A total of 412 healthy children (226 boys, 186 girls) with the age 8.6 (6.8, 10.3) years old were included in this study. The data of the prospective study were from a subgroup of the project "National Nutrition and Health Systematic Survey for 0-18 Years Old Children in China", which included children with age of 3-12 years old in Beijing rural areas. The non-dominant hand-wrist radiographs of all participants were obtained in April 2021. The Dr.Wise BA detection and analysis system was used to assess the BA according to the Tanner Whitehouse 3 (TW3) radius-ulna-short bone score (TW3-RUS), TW3 carpal bone score (TW3-Carpal), China-05 TW3-Chinese RUS (TW3-C RUS), China-05 TW3-Chinese carpal (TW3-C Carpal), and Greulich-Pyle (G-P) standards. The cases were stratified by the sex and different CA in the statistical analysis. The estimated BA obtained using different methods were compared with the CA using Wilcoxon signed ranks test.Results:The sex-stratified results showed that no significant difference was found between the estimated BA using G-P standards and CA in boys ( Z=-0.694, P=0.488), while all the other estimated BA results were statistically significantly higher than CA ( P<0.05). Stratified by both sex and CA, the estimated BA using G-P standards in 4-6 years old boy groups, as well as the estimated BA using TW3-Carpal and TW3-C Carpal standards in 11-12 years old girl groups were lower than CA, while in the other groups, the estimated BA were higher than CA. Conclusions:There were varying degrees of deviations in the BA estimations using TW3, China 05, and G-P methods for children in rural areas of Beijing. It is imperative to establish a new standard for the BA evaluation of the contemporary Chinese children.

Objective:To report the sampling study design and radiography protocol of a large-sample investigation on skeletal maturation of 3 to 18-year-old children in China.Methods:Multi-stage stratified random sampling was employed in this study. Two provinces, municipalities, or autonomous regions were randomly selected from each of the seven regions of China, including Northeast China, Northwest China, North China, Central China, East China, Southwest China, and South China. Then one rural and one urban investigation site were randomly selected from each province, municipality, or autonomous region. In total 28 sites were included. Among those sites, four residential districts were randomly selected from each urban site, and four townships from each rural site. For each residential district or township, 1-4 kindergartens, primary schools, and middle schools were chosen. Random cluster sampling was used to extract 3-<6-year-old children in kindergartens, and 6-18-year-old children in primary schools and middle schools. The investigation on skeletal maturation was sampled proportionate to the sampling of the whole study. The estimated simple size was 780 for each site, and 21 840 for all 28 sites in total. There were six groups of 3-<6-year-old children classified at 0.5-year intervals, and 12 groups of 6-18-year-old children classified at 1-year intervals. Posteroanterior position radiography of the left hand and wrist was achieved for all subjects.Results:The study was performed from August 26, 2019 to October 16, 2021. In total, 20 444 children received posteroanterior position radiography of the left hand and wrist, including 10 196 males and 10 248 females, 9 711 urban and 10 733 rural, respectively. The 3-<6-year-old group included 1 611 (male 819, female 792) subjects, and the 6 to 18-year-old group included 18 833 (male 9 377, female 9 456) subjects.Conclusion:This nationwide investigation on skeletal maturation of 3 to 18-year-old children in seven regions of China was successfully preformed. The results of this study can provide an important reference for establishing the current evaluation criteria of bone age in Chinese children and adolescents.

Objective:To prepare liquid-gas phase modified nanoparticles (TMZ/PFP/PLGA NPs) of perfluoropentane (PFP) and temozolomide (TMZ) encapsulated by polylactic-glycolic acid copolymer (PLGA), combined with low intensity focused ultrasound (LIFU) irradiation, and to investigate its ultrasound imaging ability and intervention effect on human glioma cells in vitro.Methods:TMZ/PFP/PLGA NPs were prepared by compound emulsion method. The basic physical and chemical properties and drug loading ability of TMZ/PFP/PLGA NPs were detected. CCK-8 assay was used to detect the cytotoxicity of nanoparticles in vitro and the effect of synergistic intervention with LIFU on the survival rate of glioma cells. The expression levels of apoptosis related proteins Bcl-2, Bax and caspase-3 were detected by Western blot.Results:Under transmission electron microscope, TMZ/PFP/PLGA NPs showed a circular core-shell structure with regular morphology, particle size was (137.9±63.31)nm, encapsulation efficiency of TMZ was (83.01±5.57)%, drug loading was (3.19±0.22)%. The survival rate of U251 cells was still above 70% after 24 hours of co-incubation with nanoparticles. Under the synergistic effect of LIFU irradiation, the apoptosis of U251 cells was accelerated and the survival rate of U251 cells was significantly decreased. The results of Western blot showed that the synergic intervention could significantly down-regulate the expression of apoptosis related protein Bcl-2, and significantly up-regulate the expression of Bax protein and caspase-3 protein (all P<0.05). Conclusions:TMZ/PFP/PLGA NPs have good basic physical and chemical properties. TMZ/PFP/PLGA NPs have low cytotoxicity in vitro while efficiently loading chemotherapeutic drug timozolomide. Synergistic intervention under LIFU irradiation can significantly accelerate the apoptosis of U251 glioma cells, which has a good application prospect.
