Advances in mesenchymal stem cells therapy for tendinopathies / 中华创伤杂志(英文版)

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.

Evaluation of the measles surveillance system performance in Jiading District， Shanghai from 2020 to 2022 / 上海预防医学

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.

Effects of traditional Chinese medicine on treatment outcomes in severe COVID-19 patients: a single-centre study / 中国天然药物

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.

Clinical practice and research advances in artificial liver support therapy / 临床肝胆病杂志

Artificial liver support system is one of the important therapies for liver failure， and in recent years， the role of non-bioartificial liver support system in the treatment of liver failure has been gradually recognized， with wide application in non-liver failure diseases. In clinical practice， various factors should be considered to reasonably select the timing and mode of non-bioartificial liver support therapy， and standardized， individualized， and precise treatment and optimal combination of different modes are the trend of the clinical application of artificial liver support therapy. There have been constant improvements in the key techniques of bioartificial liver support system such as seed cell source and bioreactor， and some of them have entered the stage of clinical trial. Although remarkable progress has been made in the clinical practice and research of artificial liver support therapy， there are still many challenges， and it is urgently needed to solve the problems of how to further improve its efficacy and safety through technological innovation and combination optimization and how to obtain higher-level evidence-based medical evidence through high-quality clinical trials.

Ultrasound-guided anhydrous ethanol and microwave ablation for functional parathyroid cyst: a case report / 南方医科大学学报

We report a case of functional parathyroid cyst treated by ultrasound-guided anhydrous ethanol sclerotherapy and microwave ablation. The 63-year-old female patient was diagnosed to have functional parathyroid cyst with hypercalcemia, high PTH and cystic space-occupying lesions in the neck by ultrasound, radionuclide scanning and PTH measurement of the cystic fluid. The patient refused to receive cyst resection, and anhydrous ethanol sclerotherapy with microwave ablation was performed under ultrasound guidance. The procedure was completed smoothly without any complications either during or after the operation. Follow-up examination of the patient at 18 months after the operation showed a significant reduction of the mass and normal blood calcium and iPTH levels, demonstrating a clinical cure of the patient. Ablative treatment of functional parathyroid cyst has not been documented so far. This approach provides a minimally invasive treatment modality for such cases where surgical resection is not an option, but its efficacy and safety need to be evaluated in more cases with longer follow-up time.

Association between vitamin D level and blood eosinophil count in healthy population and patients with chronic obstructive pulmonary disease / 南方医科大学学报

OBJECTIVE@#To investigate the prevalence of vitamin D deficiency and its association with blood eosinophil count in healthy population and patients with chronic obstructive pulmonary disease (COPD).@*METHODS@#We analyzed the data of a total 6163 healthy individuals undergoing routine physical examination in our hospital between October, 2017 and December, 2021, who were divided according to their serum 25(OH)D level into severe vitamin D deficiency group (< 10 ng/mL), deficiency group (< 20 ng/mL), insufficient group (< 30 ng/mL) and normal group (≥30 ng/mL). We also retrospectively collected the data of 67 COPD patients admitted in our department from April and June, 2021, with 67 healthy individuals undergoing physical examination in the same period as the control group. Routine blood test results, body mass index (BMI) and other parameters were obtained from all the subjects, and logistic regression models were used to investigate the association between 25(OH)D levels and eosinophil count.@*RESULTS@#The overall abnormal rate of 25(OH)D level (< 30 ng/mL) in the healthy individuals was 85.31%, and the rate was significantly higher in women (89.29%) than in men. Serum 25(OH)D levels in June, July, and August were significantly higher than those in December, January, and February. In the healthy individuals, blood eosinophil counts were the lowest in severe 25(OH)D deficiency group, followed by the deficiency group and insufficient group, and were the highest in the normal group (P < 0.05). Multivariable regression analysis showed that an older age, a higher BMI, and elevated vitamin D levels were all risk factors for elevated blood eosinophils in the healthy individuals. The patients with COPD had lower serum 25(OH)D levels than the healthy individuals (19.66±7.87 vs 26.39±9.28 ng/mL) and a significantly higher abnormal rate of serum 25(OH)D (91% vs 71%; P < 0.05). A reduced serum 25(OH)D level was a risk factor for COPD. Blood eosinophils, sex and BMI were not significantly correlated with serum 25(OH)D level in patients with COPD.@*CONCLUSION@#Vitamin D deficiency is common in both healthy individuals and COPD patients, and the correlations of vitamin D level with sex, BMI and blood eosinophils differ obviously between healthy individuals and COPD patients.

Effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant in Guangdong Province / 中华预防医学杂志

Objective: To evaluate the effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant. Methods: A total of 1 403 Omicron-infected patients admitted to 20 designated hospitals in Guangdong Province from January 1 to May 31, 2022, were selected as subjects in this study. A case-control study was conducted to collect the demographic data, underlying disease, vaccination status, last exposure date, gene sequencing of infected strains and clinical outcomes from the China Disease Prevention and Control Information System and Guangdong telemedicine platform. Pneumonia (common, severe and critical) and non-pneumonia (asymptomatic and mild) were selected as the case group and control group. The effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant was analyzed. Results: The median age [M (Q1, Q3)] of the subjects was 36 (27-47) years old, with males accounting for 52.25% (733 cases). The main outcome of the infection was non-pneumonia, accounting for 92.09% (1 292 cases), and the duration [M (Q1, Q3)] of the disease was 18 (14-22) days. There were 134 (9.55%), 39 (2.78%), 403 (28.72%), 437 (31.15%) and 390 (27.80%) cases with no or partial vaccination, within 90 days of primary vaccination, over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination, respectively. Multivariate logistic regression analysis showed that after adjusting for gender, age, underlying disease, and location of the report, compared with those with no or partial vaccination, the risk of developing pneumonia was lower in those with over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination [OR (95%CI) values were 0.52 (0.28-0.98), 0.39 (0.21-0.73) and 0.40 (0.21-0.77), respectively]. Cox proportional hazard regression model analysis showed that after adjusting for gender, age, underlying disease and location of the report, the duration of the disease was shorter in those who received booster vaccinated for more than 90 days compared with that in those who had no or partial vaccination [HR (95%CI): 1.26 (1.03-1.55)]. Conclusion: The inactivated SARS-CoV-2 vaccine affects the clinical outcomes of patients infected with the Omicron variant.

Association between cardiometabolic diseases and quality of life and the mediation effect of perceived stress / 中华心血管病杂志

Objective: To explore the association between cardiometabolic diseases (CMD) and quality of life, the association between CMD and perceived stress, and the mediation effect of perceived stress on the association between CMD and quality of life, and to provide evidence for the prevention and treatment of CMD and the improvement of quality of life in these patients. Methods: This is a cross-sectional study. Data were collected by the employees' physical examination of a company in Xi'an in 2021. Multiple linear regression models were used to analyze the association between the status of CMD (divided into three categories: no CMD, presence of one kind of CMD, and with≥2 kinds of CMD (≥2 kinds of CMD were defined as cardiometabolic multimorbidity (CMM)), quality of life, and perceived stress. Mediation analysis with a multi-categorical independent variable was conducted to determine the mediation effect of perceived stress on the association between CMD and quality of life. Results: Among all 4 272 participants, 1 457 (34.1%) participants had one kind of CMD and 677 (15.8%) participants had CMM. The average scores for quality of life and perceived stress were (57.5±15.7) and (16.9±7.9), respectively. Compared with participants without CMD, after adjusting for demographic and lifestyle factors, no statistically significant associations were observed between one kind of CMD and perceived stress or quality of life (both P>0.05). Perceived stress did not mediate the association between one kind of CMD and quality of life. However, participants with CMM had lower quality of life and higher perceived stress than participants without CMD. The relative total effect coefficient c (95%CI) and the relative direct effect coefficient c' (95%CI) between CMM and quality of life were -3.71 (-5.04--2.37) and -2.52 (-3.81--1.24) (both P<0.05), respectively. The relative indirect effect coefficient a2b (95%CI) of perceived stress on the association between CMM and quality of life was -1.18 (-1.62--0.77) (P<0.05). The mediation effect size was 31.8%. Conclusions: CMM is negatively associated with quality of life and positively associated with perceived stress. Perceived stress partially mediates the association between CMM and quality of life. Our results suggest that, in addition to preventing and treating CMM actively, efforts should be taken to relieve the perceived stress of people with CMM to improve their quality of life.

Efficacy and Safety of Flumatinib in Treatment of Patients with Chronic Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To analyze the efficacy and safety of flumatinib in the treatment of patients with chronic myeloid leukemia (CML).@*METHODS@#The clinical data of 56 CML patients treated with flumatinib from January 2020 to December 2021 in the First Affiliated Hospital of Nanchang University were retrospectively analyzed. Patients were divided into three groups: 35 new diagnosed CML patients treated with flumatinib (group A), 10 patients with imatinib/dasatinib intolerance (group B) and 11 patients with imatinib/dasatinib resistance (group C) switched to flumatinib treatment, respectively. The molecular response and adverse effects of flumatinib treatment were evaluated.@*RESULTS@#In group A, the early molecular response (EMR) at 3 months was 40.0%, and the major molecular response (MMR) at 6 and 12 months was 43.7% and 46.2%, respectively. In group B, the EMR was 50.0% at 3 months, and the MMR was 70.0% and 66.2% at 6 and 12 months, respectively. Among evaluable patients, 6 cases in group B achieved molecular response of 4.5 (MR4.5) at 12 months after switching to flumatinib treatment. In group C, 3 cases who switched from imatinib resistance to flumatinib achieved MR4.5 at 12 months, but 2 cases who switched from dasatinib resistance to flumatinib failed. Subgroup analysis showed significant differences in EUTOS long-term survival (ELTS) scores for patients in the medium-risk/high-risk group compared with those in the low-risk group for 3-month EMR (18.8% vs 57.9%), 6-month MMR (15.4% vs 63.2%) and 12-month MR4.5 (15.4% vs 69.2%) (P =0.036, P =0.012,P =0.015). The most common adverse effect in group A was thrombocytopenia, accounting for 54.5%, and 22.8% (8/35) patients discontinued the drug due to haematological adverse effects. Compared with patients who did not discontinue the drug or whose recovery time from discontinuation due to haematological toxicity was <1 month, patients whose recovery time from discontinuation was ≥1 month had a significantly worse 3-month EMR, 6-month MMR and 12-month MR4.5 (P =0.028, P =0.021, P =0.002).@*CONCLUSIONS@#Flumatinib has better molecular response and tolerance in patients with primary, imatinib/dasatinib-intolerant or resistant CML. Medium-risk/high-risk in ELTS score and time to recovery from discontinuation due to haematological toxicity ≥1 month are important factors influencing achievement of better molecular response in flumatinib treatment.

Phenotype and genotype characteristics of children with cardiomyopathy associated with MYH7 gene mutation: a retrospective analysis / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical phenotype and genotype characteristics of children withcardiomyopathy (CM) associated with MYH7 gene mutation.@*METHODS@#A retrospective analysis was conducted on the medical data of five children with CM caused by MYH7 gene mutation who were diagnosed and treated in the Department of Cardiology, Hebei Children's Hospital.@*RESULTS@#Among the five children with CM, there were three girls and two boys, all of whom carried MYH7 gene mutation. Seven mutation sites were identified, among which five were not reported before. Among the five children, there were three children with hypertrophic cardiomyopathy, one child with dilated cardiomyopathy, and one child with noncompaction cardiomyopathy. The age ranged from 6 to 156 months at the initial diagnosis. At the initial diagnosis, two children had the manifestations of heart failure such as cough, shortness of breath, poor feeding, and cyanosis of lips, as well as delayed development; one child had palpitation, blackness, and syncope; one child had fever, runny nose, and abnormal liver function; all five children had a reduction in activity endurance. All five children received pharmacotherapy for improving cardiac function and survived after follow-up for 7-24 months.@*CONCLUSIONS@#The age of onset varies in children with CM caused by MYH7 gene mutation, and most children lack specific clinical manifestations at the initial diagnosis and may have the phenotype of hypertrophic cardiomyopathy, dilated cardiomyopathy or noncompaction cardiomyopathy. The children receiving early genetic diagnosis and pharmacological intervention result in a favorable short-term prognosis.

Protective effect of Shenfu Injection on regulation of autophagy in rats with chronic heart failure based on PI3K/Akt/mTOR pathway / 中国中药杂志

This study aimed to investigate the mechanism and target sites of Shenfu Injection in the intervention of chronic heart fai-lure based on the PI3K/Akt/mTOR autophagy signaling pathway. The chronic heart failure model was induced in rats by subcutaneous injection of isoproterenol. The model rats were randomly divided into model group, Shenfu Injection group, and 3-methyladenine autophagy inhibitor(3-MA) group. A normal group was also set up. After 15 days of administration, cardiac function indexes of the rats were detected by echocardiography. The serum N-terminal pro-B-type natriuretic peptide(NT-proBNP) levels were measured using the ELISA. HE and Masson staining was performed to observe the morphological changes in myocardial tissues, and electron microscopy was used to observe the autophagosomes in myocardial tissues. Western blot was conducted to measure the changes in autophagy-related proteins(LC3 Ⅱ/Ⅰ and p62), PI3K, Akt, mTOR, and phosphorylation levels. The results showed that compared with normal group, model group in rats led to reduced cardiac function, significant activation of cardiac autophagy, increased fibrotic lesions in myocardial tissues, structural disorder of the myocardium, increased autophagosomes, and cytoplasmic vacuolization. Compared with model group, Shenfu Injection group in rats led to cardiac function significantly improved, myocardial fibrosis decreased, and the number of autophagosomes and cytoplasmic vacuolization decreased. The phosphorylation levels of PI3K, Akt, and mTOR were significantly increased(P<0.01). In the 3-MA group, autophagy was inhibited through the activation of the PI3K/Akt/mTOR signaling pathway, resulting in improved cardiac function, reduced myocardial fibrosis, and no significant cytoplasmic vacuolization. The findings suggest that Shenfu Injection can activate the PI3K/Akt/mTOR signaling pathway and inhibit autophagy, thereby improving cardiac function.

Pathogenesis of chronic heart failure in rats based on ferroptosis-mediated oxidative stress and intervention effect of Shenfu Injection / 中国中药杂志

This study aims to investigate the pathogenesis of chronic heart failure based on ferroptosis-mediated oxidative stress and predict the targets of Shenfu Injection in treating chronic heart failure. A rat model of chronic heart failure was established by the isoproterenol induction method. According to the random number table method, the modeled rats were assigned into three groups: a model group, a Shenfu Injection group, and a ferrostatin-1(ferroptosis inhibitor) group. In addition, a normal group was designed. After 15 days of intervention, the cardiac mass index and left ventricular mass index were determined. Echocardiography was employed to eva-luate the cardiac function. Hematoxylin-eosin staining and Masson staining were employed to reveal the pathological changes and fibrosis of the heart, and Prussian blue staining to detect the aggregation of iron ions in the myocardial tissue. Transmission electron microscopy was employed to observe the mitochondrion ultrastructure in the myocardial tissue. Colorimetry was adopted to measure the levels of iron metabolism, lipid peroxidation, and antioxidant indicators. Flow cytometry was employed to measure the content of lipid-reactive oxygen species(ROS) and the fluorescence intensity of ROS. Western blot and RT-qPCR were employed to determine the protein and mRNA levels, respectively, of ferroptosis-related factors in the myocardial tissue. The results showed that the rats in the model group had reduced cardiac function, elevated levels of total iron and Fe~(2+), lowered level of glutathione(GSH), increased malondialdehyde(MDA), decreased superoxide dismutase(SOD) and glutathione peroxidase(GSH-Px), and rising levels of ROS and lipid-ROS. In addition, the model group showed fibrous tissue hyperplasia with inflammatory cell infiltration and myocardial fibrosis, iron ion aggregation, and characteristic mitochondrial changes specific for iron death. Moreover, the model group showcased upregulated protein and mRNA levels of p53 and COX2 and downregulated protein and mRNA levels of GPX4, FTH1, SLC7A11, and Nrf2 in the myocardial tissue. The intervention with Shenfu Injection significantly improved the cardiac function, recovered the iron metabolism, lipid peroxidation, and antioxidant indicators, decreased iron deposition, improved mitochondrial structure and function, and alleviated inflammatory cell infiltration and fibrosis. Furthermore, Shenfu Injection downregulated the mRNA and protein levels of p53 and COX2 and upregulated the mRNA and protein levels of GPX4, FTH1, SLC7A11, and Nrf2 in the myocardial tissue. Shenfu Injection can improve the cardiac function by regulating iron metabolism, inhibiting ferroptosis, and reducing oxidative stress injury.

Comprehensive Evaluation of Health Status of Traditional Chinese Medicine Constitution based on Improved Radar Chart / 中医杂志

ObjectiveTo present the health status of traditional Chinese medicine （TCM） constitutions more intuitively and comprehensively based on improved radar chart. MethodsParticipants who completed a 26-week comprehensive intervention based on TCM constitution from February 2013 to January 2014 in Zhuhai branch of Guangdong Provincial Hospital of Chinese Medicine were included in the study. They were divided into groups according to gender and age， i.e. young， middle-aged， and elderly male and female groups. TCM constitution scale and health survey short form （SF-36） were used to evaluate the 9 basic TCM constitution types and quality of life at three time points， including pre-intervention （T1）， at 13-week intervention （T2）， and at 26-week intervention （T3）. The improved radar charts were drawn to visually present the comprehensive evaluation results on the health status of 9 TCM constitutions， and graphic features （area S value， perimeter L value） were extracted to construct a comprehensive health index for TCM constitutions （H value）. Spearman correlation analysis was used to analyze the correlation between H value and SF-36 total score. ResultsAmong the included 509 participants， there were 45 elderly male， 76 elderly female， 60 middle-aged male， 140 middle-aged female， 53 young male and 135 young female. The radar charts for comprehensive evaluation of TCM constitution health status showed that the total areas for all groups increased at T3 compared to T1， with the most significant increase in the young population. In the middle-aged population， the fan-shaped areas of certain constitutions decreased at T2 than T1. At T3， the radar chart shapes for females were more balanced than males in the same age group. By calculating the features of function graphs， it was found that the S， L， and H values for the elderly population were relatively higher than those for the middle-aged and young population with the same gender， and the young population increased by highest ratio. The values measured at T3 compared to T1 showed average increase of 26% for S value （11% for the middle-aged and 14% for the elderly）， 22% for L value （10% for the middle-aged and the elderly each）， and 22% for H value （10% for the middle-aged and 9% for the elderly）. The female had lower S and L values， as well as higher H value than the male of the same age group measured at T3. The correlation coefficient between the H value of all participants and the total SF-36 score was 0.662 （P＜0.01）. ConclusionThe comprehensive evaluation model for the health status of TCM constitution based on the improved radar chart constructed in this study can present the health status of TCM constitutions and intervention effectiveness more comprehensively and intuitively. It is suggested to regulate the constitution in pursuit of the dynamic balance of the constitution health status， as well as consider the parts from the whole， and put focus on the balance of nine TCM constitutions.

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 observe the effect of video-based mirror therapy on lower limb motor function, walking ability, and balance of stroke patients at recovery stage. MethodsFrom January to October, 2022, 43 stroke patients in Beijing Bo'ai Hospital were randomly divided into control group (n = 22) and mirror therapy group (n = 21). Both groups received routine rehabilitation, and the mirror therapy group received video-based mirror therapy additionally, for four weeks. They were assessed with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Functional Ambulation Category (FAC) and Berg Balance Scale (BBS) before and after treatment. ResultsAfter treatment, the scores of FMA-LE, FAC and BBS improved significantly in both groups (|t| > 6.205, P < 0.001), and the scores of FMA-LE and BBS were better in the mirror therapy group than in the control group (|t| > 2.164, P < 0.05). ConclusionCombining with video-based mirror therapy could facilitate to improve the lower limb motor function and balance ability of stroke patients at recovery stage.

Domestic and international researches related to postpartum rehabilitation in the last decade: a visualized analysis / 中国康复理论与实践

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.

Application of three-dimensional imaging device to colonoscopy / 中华消化内镜杂志

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.

Effect of muscle mass reduction on the progression of coronary artery calcification in maintenance hemodialysis patients / 中华肾脏病杂志

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.
