RESUMO

ObjectiveTo prepare a rat model of heart failure after myocardial infarction by ligation of the anterior descending branch of the left coronary artery, and to observe the effect of Shenfu Yixin granules on the mitochondrial dynamics of rats with heart failure. MethodFifty SD male rats were randomly taken ten as the sham operation group and the rest as modeling group. The rat model of heart failure after myocardial infarction was prepared by ligation of anterior descending branch of left coronary artery. According to the left ventricular ejection fraction(LVEF) on the 28th day after operation, the model rats were randomly divided into the model group, Shenfu Yixin granule low-dose and high-dose groups(3.011, 15.055 g·kg-1) and sacubitril valsartan sodium group(20.83 mg·kg-1). Each administration group was gavaged daily with the corresponding dose of drug solution, while the sham operation group and model group were given the same amount of normal saline once a day for 28 days, with 6 rats in each group. Ultrasound was used to detect the cardiac function parameters, rat heart mass and body mass were weighed to calculate the cardiac mass index, enzyme linked immunosorbent assay(ELISA) was used to detect serum brain natriuretic peptide(BNP) and soluble growth stimulation expressed gene 2 protein(sST2) levels. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of the myocardium. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to detect the mRNA and protein expression of mitochondrial fusion protein 1/2(Mfn1/2), optic atrophy protein 1(Opa1), dynamin-related protein 1(Drp1) and fission protein 1(Fis1). ResultCompared with the sham operation group, the mRNA and protein expression of LVEF, Mfn1, Mfn2, Opal in the model group decreased(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels increased(P<0.05). Compared with the model group, the expression of LVEF, Mfn1, Mfn2, Opal mRNA and protein increased in Shenfu Yixin granule high-dose and sacubitril valsartan sodium groups(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels decreased(P<0.05). Pathological observation showed that compared with the sham operation group, the model group had disordered arrangement of myocardial cells, inflammatory cell infiltration and myocardial fibrosis. Compared with the model group, the degree of inflammatory cell infiltration, myocardial or interstitial fibrosis was improved and alleviated in all administered groups. ConclusionShenfu Yixin granules can resist heart failure, reduce cardiac mass index, decrease BNP and sST2 contents, and improve cardiac function. Its mechanism may be related to the adjustment of mitochondrial dynamics.

RESUMO

Objective:To explore the predictive value of multimodal ultrasound features combined with serum matrix metalloproteinase-9 (MMP-9) detection for tumor recurrence of breast cancer after breast-conserving surgery.Methods:A total of 194 patients with breast cancer who underwent breast-conserving surgery in Affiliated Hospital of Jining Medical College from Jan. 2017 to May. 2018 were selected. Routine ultrasound, automated breast volume imaging and contrast-enhanced ultrasound were performed before surgery. Logistic regression equation was used to analyze the risk factors affecting local tumor recurrence after breast-conserving surgery, and ROC curve was drawn to analyze the predictive value of multimodal ultrasound features combined with serum MMP-9 for local tumor recurrence after breast-conserving surgery.Results:After 5 years of follow-up, 29 out of 194 breast cancer patients who underwent breast-conserving surgery had local recurrence and metastasis. There were no significant differences in tumor diameter, spiculation sign, convergence sign, Alder blood flow grade, enhancement sequence, pattern and enhancement intensity between the two groups ( P>0.05 t=1.48, P=1.451; χ2=0.55, P=0.460; χ2=0.50, P=0.478; χ2=0.60, P=0.439; χ2=0.50, P=0.780; χ2=0.04, P=0.981; χ2=0.13, P=0.716). Logistic regression analysis showed that irregular tumor shape, small calcification,Peripheral radial enhancement, perfusion defect and abnormal elevation of serum MMP-9 were independent risk factors for local recurrence of breast cancer after breast-conserving surgery ( P=0.034, 95%CI=1.177~62.266; P=0.048, 95%CI=1.022~58.397; P=0.045, 95%CI=1.100~56.756; P=0.043, 95%CI=1.079~ 60.937; P=0.044, 95%CI=1.000~1.026). ROC curve showed that the AUC of multimodal ultrasound features combined with serum MMP-9 in predicting local tumor recurrence after breast-conserving surgery was 0.970, and the sensitivity and specificity were 98.63% and 91.67%, respectively.

RESUMO

Objective:To investigate the relationship between psychologicalresilience and irrational parenthood cognition and fertility life quality in female patients with in vitro fertilization-embryo transfer, and to analyze the mediating effect of psychological resilience on irrational parenthood cognition and fertility life quality, so as to provide guidance for infertility patients to improve their psychological resilience and fertility life quality.Methods:A cross-sectional study method was used to conveniently sample 460 female patients with in vitro fertilization-embryo transfer who were admitted to the Women′s Hospital, School of Medicine Zhejiang University from October 2022 to April 2023.General data questionnaire, Connor-Davidson Resilience Scale, Irrational Parenthood Cognitions Questionnaire and the Fertility Quality of Life were used for investigation.Results:A total of 449 valid questionnaires were retrieved. Patients aged (33.31 ± 4.99) years old. The total scores of irrational parenthood cognition, psychological resilience and the fertility quality of life were (38.73 ± 9.31), (63.19 ± 15.40) and (68.18 ± 11.89) points respectively for female patients with IVF-ET. The total score of irrational parenthood cognition was negatively correlated with the total score of fertility quality of life ( r = - 0.513, P<0.01), and the total score of psychological resilience was positively correlated with the total score of fertility quality of life ( r = 0.424, P<0.01). Pychological resilience played a partial mediating role between irrational parenthood cognition and fertility life quality, with the mediating effect accounting for 28.01% of the total effect. Conclusions:The irrational parenthood cognition of female patients with IVF-ET is at a medium level, and the psychological resilience and the fertility quality of life are at a low level. The irrational parenthood cognition has a direct negative predictive effect on the fertility life quality of patients, while the psychological resilience is a positive predictor of fertility life quality. Irrational parenthood cognition can directly or indirectly affect patients′ fertility life quality through psychological resilience. Clinical medical staff should take effective measures to reduce patients′ irrational parenthood cognition level and improve their psychological resilience, so as to improve patients′ fertility life quality.

RESUMO

OBJECTIVE:Chronic ankle instability is mainly characterized by symptoms such as muscle weakness,intermittent pain,and repeated sprains,which seriously affect exercise and daily life.Loss of proprioception,prolongation of fibular reaction time,and weakening of valgus force may be the main symptoms of chronic ankle instability,so exercise intervention can effectively improve the symptoms related to ankle instability.Meta-analysis was used to quantitatively evaluate the effect of balance training on the rehabilitation intervention of chronic ankle instability,providing a reliable theoretical basis and practical basis for chronic ankle instability patients to scientifically formulate exercise prescriptions. METHODS:The randomized controlled trial of balance training on symptom rehabilitation and dynamic equilibrium of patients with chronic ankle instability was retrieved on CNKI,VIP,Web of Science,and PubMed.The literature was published from the inception to November 23,2022.Two reviewers were included to evaluate the quality of the included literature based on the physical therapy evidence scale.The primary outcome measure is the Self Functional Rating Scale,and the secondary outcome measure is the Star Shift Balance Test,both of which are continuous variables.Forest mapping,meta-regression,subgroup analysis,sensitivity analysis,and publication bias evaluation were performed on the included literature using RevMan 5.3 and Stata-SE 15 software. RESULTS:(1)A total of 18 articles of randomized controlled trials were screened and 641 patients with chronic ankle instability were included in the study.Overall,the methodological quality of the literature was relatively high.(2)Meta-analysis results showed that balance training improved the functional rehabilitation effect of chronic ankle instability patients(SMD=0.82,95%CI:0.41-1.23,P<0.000 1).Meta-regression exhibited that intervention time might be the main reason for heterogeneity(P=0.008).(3)The subgroup analysis results revealed that 6 weeks of intervention(SMD=0.98,95%CI:0.31-1.65,P=0.03),more than 3 interventions per week(SMD=0.87,95%CI:0.30-1.44,P=0.003),and each intervention time less than 20 minutes(SMD=0.89,95%CI:0.61-1.66,P<0.000 1)were the best rehabilitation plans to improve the functional rehabilitation effect of chronic ankle instability patients.(4)Meta-analysis results also showed that balance training improved the stretching degree of the anterior side(SMD=0.56,95%CI:0.31-0.80,P<0.05),posterior inner side(SMD=0.88,95%CI:0.45-1.32,P<0.05),and posterior outer side(SMD=0.84,95%CI:0.22-1.46,P<0.05)of the star shift balance test. CONCLUSION:Current clinical evidence shows that balance training can improve ankle instability symptoms and elevate dynamic equilibrium ability in chronic ankle instability patients.It is recommended to intervene more than 3 times a week,with each intervention lasting less than 20 minutes,to achieve better rehabilitation effects.

RESUMO

OBJECTIVE:Clinically,chronic ankle instability has symptoms such as muscle weakness,loss of control and repeated sprains.These symptoms can be effectively improved by means of exercise intervention.Here,we conducted a comprehensive quantitative evaluation of the effects of exercise intervention on chronic ankle instability at home and abroad through Meta-analysis,and examined the moderating effects of different exercise interventions on chronic ankle instability in terms of effect size and exercise dose. METHODS:CNKI,WanFang,Web of Science,EBSCO-SPORTD and PubMed were searched and screened for relevant literature regarding randomized controlled trials of an exercise intervention program against chronic ankle instability.Included literature was analyzed by using Review Manager 5.3 and Stata-SE 15. RESULTS:A total of 52 documents were included with 1 880 patients with chronic ankle instability.Meta-analysis showed that exercise intervention could improve the functional score of patients with chronic ankle instability to a large amount.Neuromuscular control training,a 12-week intervention cycle,and two weekly interventions of>60 minutes are the best protocol for improving instability symptoms in patients with chronic ankle instability.Exercise intervention could improve the dynamic balance of patients with chronic ankle instability to reach the medium equivalent stress.The best exercise program to improve the dynamic balance ability is a combination of neuromuscular control training and hip strength training,with an exercise dose of 30-60 minutes,two or three times per week,for 8 weeks in total. CONCLUSION:Different exercise forms have a good effect on improving the unstable symptoms and dynamic balance ability of patients with chronic ankle instability,among which neuromuscular control training has a more comprehensive effect on improving chronic ankle instability.It is recommended that a multifunctional combination of training forms be used as a means of rehabilitation rather than a single form of exercise.

RESUMO

Type 1 diabetes mellitus is a T-cell-mediated autoimmune disease that commonly affects adolescents, characterized by progressive destruction of pancreatic β-cells, absolute insulin deficiency, and hyperglycemia. The pathogenesis of type 1 diabetes mellitus is complex and is believed to be mainly associated with immunity, environment, and genetics. There is increasing evidence that gut microbiota is closely related to the occurrence of type 1 diabetes mellitus. This article focuses on the immune mechanisms and roles of gut microbiota and its derivatives in the development of type 1 diabetes mellitus from the perspectives of innate and adaptive immunity. Additionally, it introduces therapeutic approaches targeting gut microbiota for the treatment of type 1 diabetes mellitus.

RESUMO

Autoimmune paranodopathy (APN) has emerged as an independent rare disease,which is medicated by autoimmune antibodies against the essential complex of paranodal region of Ranvier. The antibodies include anti-neurofascin 155 antibody, anti-contactin-1 antibody and anti-contactin-associated protein 1 antibody. Although there are many similarities between APN and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), patients with APN have relatively unique clinical features, pathogenesis, histopathological results and responses to intravenous immune globulin, distinguishing from typical CIDP. The predominant subclass of IgG among pathogenic antibodies is IgG4, meanwhile, other subclasses have been rarely reported. Early detecting the APN related antibodies and their subclasses not only helps to clarify the diagnosis, but also provides valuable clinical information for the selection of precise treatment and prognosis.

RESUMO

【Objective】 To understand the current situation of social emotional competence of infants and toddlers, and analyze its relationship with home rearing environment, in order to provide the basis for improving the level of infant social emotional development. 【Method】 A study was conducted on 390 individuals from a child health institution in Hubei and Henan provinces.The "Infant and Toddler Social-Emotional Assessment Scale" and "1 - 3 Years Child Home Rearing Environment Scale" were used to investigate the social emotions ability and home rearing environment of infants and toddlers. 【Results】 A total of 390 valid questionnaires were collected in this survey, of which 199 were boys (51.0%) and 191 girls (49.0%). The average age of infants was (27.13±6.86)months.The age distribution is mainly among infants and young children aged 24 to 36 months, with a total of 305 people (78.2%). The caregiver′s registered residence (Z=-3.570), father′s education level (H=17.106), mother′s education level (H=7.980), per capita monthly income of the family (H=13.986), and the home rearing environment (Z=-8.881) had statistical significance on the social emotional competence of infants(P<0.05 or <0.01).There was a significant positive correlation between family rearing environment and infants′ social emotion (r=0.582, P<0.01).Multiple regression analysis showed that the social adaptation/self-care(β=0.30, 95%CI: 0.18 - 0.52, P<0.01)and language cognition dimensions(β=0.22, 95%CI: 0.07 - 0.59, P<0.05) in the home rearing environment had a statistically significant impact on the social emotional ability of infants and toddlers. 【Conclusion】 The home rearing environment is closely related to the social emotional development of infants and young children.Improve the parenting knowledge and skills of the main caregivers of infants and young children, build a good family rearing environment for infants and young children, which is beneficial to promote the development of children′s social emotions.
