Music therapy as a non-pharmacological intervention for persons living with dementia: client assessment and types of music therapy interventions

Geriatric giants account for the five most prevalent morbidities that cause immense decline in functional capacity and decreased quality of life. Immobility, instability leading to falls and fractures, incontinence, impaired cognition (dementia) and iatrogenesis affect majority of the ageing elderly leading to dependency, caregiving and associated burden among caregivers. Concept of non-pharmacological interventions in dementia care: interventions that involve non-pharmacological (non-medicinal) measures, have proven benefits to the people living with dementia (PLWD). music therapy, nature therapy that involves nature walks and living amidst natural spaces, have shown to have immense biophilia effects on the various organ systems in the human body. Immense health benefits have been documented among PLWD: dawn phenomenon is a clinical phenomenon where the PLWD experiences agitation, aggression and loud speech in the evenings associated with dementia. Out of all the seven studies published, there were significant improvements in mood, reduction in aggressive behavior, improving anxiety symptoms, reducing caregiver burnout and improving overall quality of life of the people living with dementia and their caregivers. With promising results among various interventional studies across the world, NPI is an important intervention with minimal to nil side effects with long term benefits on frequent administration.

O Valor Preditivo do Índice Prognóstico Inflamatório para Detecção de No-Reflow em Pacientes com Infarto do Miocárdio com Supradesnivelamento do Segmento ST / The Predictive Value of the Inflammatory Prognostic Index for Detecting No-Reflow in ST-Elevation Myocardial Infarction Patients

Resumo Fundamento: O no-reflow (NR) é caracterizado por uma redução aguda no fluxo coronário que não é acompanhada por espasmo coronário, trombose ou dissecção. O índice prognóstico inflamatório (IPI) é um novo marcador que foi relatado como tendo um papel prognóstico em pacientes com câncer e é calculado pela razão neutrófilos/linfócitos (NLR) multiplicada pela razão proteína C reativa/albumina. Objetivo: Nosso objetivo foi investigar a relação entre IPI e NR em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST) submetidos a intervenção coronária percutânea primária (ICPp). Métodos: Um total de 1.541 pacientes foram incluídos neste estudo (178 com NR e 1.363 com refluxo). A regressão penalizada LASSO (Least Absolute Shrinkage and Select Operator) foi usada para seleção de variáveis. Foi criado um nomograma baseado no IPI para detecção do risco de desenvolvimento de NR. A validação interna com reamostragem Bootstrap foi utilizada para reprodutibilidade do modelo. Um valor de p bilateral <0,05 foi aceito como nível de significância para análises estatísticas. Resultados: O IPI foi maior em pacientes com NR do que em pacientes com refluxo. O IPI esteve associado de forma não linear com a NR. O IPI apresentou maior capacidade discriminativa do que o índice de imunoinflamação sistêmica, NLR e relação PCR/albumina. A adição do IPI ao modelo de regressão logística multivariável de base melhorou a discriminação e o efeito do benefício clínico líquido do modelo para detecção de pacientes com NR, e o IPI foi a variável mais proeminente no modelo completo. Foi criado um nomograma baseado no IPI para prever o risco de NR. A validação interna do nomograma Bootstrap mostrou uma boa capacidade de calibração e discriminação. Conclusão: Este é o primeiro estudo que mostra a associação de IPI com NR em pacientes com IAMCSST submetidos a ICPp.

Abstract Background: No-reflow (NR) is characterized by an acute reduction in coronary flow that is not accompanied by coronary spasm, thrombosis, or dissection. Inflammatory prognostic index (IPI) is a novel marker that was reported to have a prognostic role in cancer patients and is calculated by neutrophil/lymphocyte ratio (NLR) multiplied by C-reactive protein/albumin ratio. Objective: We aimed to investigate the relationship between IPI and NR in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). Methods: A total of 1541 patients were enrolled in this study (178 with NR and 1363 with reflow). Lasso panelized shrinkage was used for variable selection. A nomogram was created based on IPI for detecting the risk of NR development. Internal validation with Bootstrap resampling was used for model reproducibility. A two-sided p-value <0.05 was accepted as a significance level for statistical analyses. Results: IPI was higher in patients with NR than in patients with reflow. IPI was non-linearly associated with NR. IPI had a higher discriminative ability than the systemic immune-inflammation index, NLR, and CRP/albumin ratio. Adding IPI to the baseline multivariable logistic regression model improved the discrimination and net-clinical benefit effect of the model for detecting NR patients, and IPI was the most prominent variable in the full model. A nomogram was created based on IPI to predict the risk of NR. Bootstrap internal validation of nomogram showed a good calibration and discrimination ability. Conclusion: This is the first study that shows the association of IPI with NR in STEMI patients who undergo pPCI.

Clinical study of percutaneous cement discoplasty for treating elderly patients with vacuum phenomenon-associated lumbar instability / 西安交通大学学报(医学版)

【Objective】 To investigate the clinical efficacy and significance of percutaneous cement discoplasty (PCD) in treating elderly patients with spinal instability and vacuum phenomenon on imaging. 【Methods】 We retrospectively analyzed 27 patients with spinal instability and vacuum phenomenon on imaging who underwent PVABC between June 2019 and September 2022. We recorded the surgery duration, bone cement usage, intraoperative bleeding, and total hospitalization time. We evaluated the improvement in pain and lumbar function by comparing pre- and postoperative visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and lumbar Japanese Orthopedic Association (JOA) scores. We also compared the change in intervertebral height and the distribution rate of bone cement in the intervertebral space by pre- and postoperative imaging data. 【Results】 All the 27 patients who underwent PCD had effective follow-up. The mean hospitalization time was (4.2±1.85) days, and the mean surgery duration was (32.3±4.51), (53.6±12.17), (74.4±6.33), and (90.0±10.36) minutes for single-, double-, triple-, and quadruple-level procedures, respectively. The intraoperative bleeding volume ranged from 2 to 13 mL, which was significantly lower than that of traditional intervertebral fusion surgery. Postoperative VAS pain scores, ODI scores, and JOA scores were significantly improved compared to those before surgery. In terms of imaging, the intervertebral height of the patients improved after surgery, and the distribution of bone cement in the intervertebral space was relatively good in the operated segments. Mechanical stability of the spine was restored. 【Conclusion】 For patients who are not suitable for open surgery due to severe complications, PCD is a feasible treatment option.

Clinical research progress on corticotomy and modified techniques for accelerating orthodontic tooth movement / 口腔疾病防治

@#Adjunctive interventions for accelerating orthodontic tooth movement have been a hot topic of interest in orthodontics. Prolonged orthodontic treatment is often associated with multiple potential complications, such as decalcification, caries, root resorption, and gingival inflammation. Therefore, applying adjunctive interventions that accelerate orthodontic tooth movement and reduce the duration of orthodontic treatment can provide patients with numerous benefits that are of profound clinical significance. Currently, adjunctive interventions for accelerating orthodontic tooth movement can be divided into two main categories: surgical and nonsurgical. Surgical interventions, represented by corticotomy and modified corticotomy procedures, are the most common in clinical practice and can minimize the treatment duration, augment alveolar bone, and expand the range of orthodontic tooth movement. However, these procedures are inevitably traumatic and have many risks and limitations that prevent them from being widely used in clinical practice. In recent years, multiple modified corticotomy techniques, such as corticision, piezocision, micro-osteoperforation, and discision, have been proposed; these techniques can reduce soft and hard tissue damage and the incidence of postoperative complications and are relatively easy to perform in the clinic. Corticotomy and other improved surgical techniques can shorten the duration of orthodontic treatment to a certain extent and promote the recovery of periodontal health with no adverse effects on periodontal, dental, or pulp tissues. However, in clinical application, several potential side effects (such as periodontal tissue damage, root resorption, loss of pulp vitality, etc) and shortcomings need further research with long-term follow-up.

Establishment of an animal model of no-reflow ischemic stroke and the multidimensional evaluation system / 中国神经精神疾病杂志

Objective The purpose of this study was to explore a suitable method to model no-reflow phenomenon following ischemic stroke and to evaluate perfusion decrease from multiple perspectives.Methods Laser scatter contrast imaging and two-photon live imaging were used to compare transient middle cerebral artery occlusion in C57BL/6 and BALB/c mice and perfusion alterations in BALB/c mice with 1 or 1.5 h of ischemia.Several imaging techniques including laser scatter contrast imaging,low and higher magnification images of perfused brain slices and two-photon microscopy to monitor erythrocyte flow rate and flux were used to assess in vivo dynamics as well as whole brain sections and microvasculature for decreased cerebral perfusion after transient middle cerebral artery occlusion.Infarct size and behavioral deficits were assessed with microtubule-associated protein 2 staining and behavioral scoring.Results In C57BL/6 mice,most capillaries in the middle cerebral artery region remained flowing during ischemia,whereas most capillaries were blocked in BALB/c mice.In addition,cortical perfusion at 24 h of recanalization was significantly reduced to 76.1%of baseline following 1.5 h of ischemia in BALB/c mice(P=0.046 compared with the sham group),whereas for it was reduced to 79.9%following 1h of ischemia which was not significantly different from the sham group(P=0.299).Transient middle cerebral artery occlusion in BALB/c mice for 1.5 h resulted in a reduction in whole-brain perfusion to 75.1%(P＜0.001 compared with the sham group),and erythrocyte flow rate assessed by two-photon live-imaging of erythrocyte flow on the cortical surface of the middle cerebral artery basin was reduced to 50.3%of baseline levels at 24 h of recanalization(P=0.010 compared with the sham group),and erythrocyte flux decreased to 38.9%of baseline levels(P= 0.010 compared with the sham group);high-magnification imaging of sections assessed an approximately 76%reduction in the length of capillaries with perfusion(P=0.0001 compared with the sham group),and a reduction in the fraction of the total volume occupied by perfused capillaries by an approximately 76%reduction(P＜0.001 compared with the sham-operated group).Microtubule-associated protein 2 staining suggested that transient middle cerebral artery occlusion for 1.5 h in BALB/c mice resulted in infarcts that accounted for approximately 36%of the total cerebral area and behavioral scores elevated to 9,suggesting behavioral deficits.Conclusion Transient ischemia in BALB/c mice for 1.5 h resulted in a significant decrease in cerebral perfusion as well as capillary no-reflow and thus can model the no-reflow phenomenon following ischemic stroke.The combination of laser scatter contrast imaging,low magnification and higher magnification images of perfused brain slices,and two-photon microscopy live imaging allows for a multifaceted assessment of perfusion changes.

Fenómeno de Milking secundario a puente intramiocárdico en paciente con bloqueo trifascicular

Introducción: los puentes intramiocárdicos son una modificación anatómica de la circulación coronaria que consisten en secciones anormales en el espesor del miocardio que al formar segmentos tunelizados e incorporarse al epicardio, provocan un ordeñamiento vascular llamado fenómeno de Milking durante la compresión sistólica extrínseca, el cual es responsable de las manifestaciones clínicas y las alteraciones electrocardiográficas. Se describe un caso clínico con el objetivo de comunicar a la comunidad científica las características clínicas, eléctricas y coronariográficas de una paciente con síndrome coronario agudo con bloqueo trifascicular y fenómeno de Milking por puente intramiocárdico. Caso clínico: mujer de56 años, con antecedentes de hipertensión arterial, obesidad e historia de ingresos frecuentes por episodios de angina inestables; fue admitida por angina inestable aguda más bloqueo trifascicular y se confirmó puente intramiocárdico en el segmento medio distal de la arteria descendente anterior izquierda. La optimización de la terapia antiisquémica se basó en Carvedilol, previa implantación de marcapaso permanente. Discusión: los puentes intramiocárdicos causan reducción dinámica de la luz del vaso epicárdico coronario y cuando resulta mayor del 50% condiciona el fenómeno de Milking, el cual es más frecuente en los segmentos medio y distal de la arteria descendente anterior izquierda, su evolución es favorable y responden a la terapéutica con ß bloqueadores de forma adecuada. Conclusiones: la correlación diagnóstica facilitó la aplicación de una conducta invasiva con estimulación transvenosa permanente que permitió iniciar tratamiento betabloqueante lo cual no hubiera sido posible por el trastorno de la conducción intraventricular.

Introduction: Intramyocardial bridges are an anatomical modification of the coronary circulation consisting of abnormal sections in the thickness of the myocardium that, when forming tunnel segments and incorporating into the epicardium, cause vascular milking, the so-called milking phenomenon, during extrinsic systolic compression, which is responsible for the clinical manifestations and electrocardiographic alterations. A clinical case is described with the aim of providing the scientific community with the clinical, electrical and coronary angiographic characteristics of a patient with acute coronary syndrome with trifascicular block and milking phenomenon due to intramyocardial bridging. Case Report: A 56-year-old woman with a history of hypertension, obesity, and frequent admissions for episodes of unstable angina was admitted for acute unstable angina plus trifascicular block and intramyocardial bridging was confirmed in the distal middle segment of the left anterior descending artery. Optimization of anti-ischemic therapy was based on carvedilol after implantation of a permanent pacemaker. Discussion: Intramyocardial bridges cause a dynamic reduction of the coronary epicardial vessel lumen and when it is greater than 50% it causes a milking phenomenon, which is more frequent in the middle and distal segments of the left anterior descending artery, its evolution is favorable and responds adequately to ß-blocker therapy. Conclusions: The diagnostic correlation facilitated the application of an invasive approach with permanent transvenous stimulation, allowing the initiation of beta-blocker treatment, which would not have been possible due to the intraventricular conduction disorder.

Introdução: As pontes intramiocárdicas são uma modificação anatómica da circulação coronária constituída por secções anómalas na espessura do miocárdio que, ao formarem segmentos em túnel e ao incorporarem-se no epicárdio, provocam a ordenha vascular, o chamado fenómeno de ordenha, durante a compressão sistólica extrínseca, responsável pelas manifestações clínicas e alterações electrocardiográficas. Descreve-se um caso clínico como objetivo de dar a conhecer à comunidade científica as características clínicas, eléctricas e coronariográficas de um doente com síndrome coronário agudo com bloqueio trifascicular e fenómeno de milking por bridging intramiocárdico. Relato de Caso: Mulher de 56 anos, com antecedentes de hipertensão arterial, obesidade e internamentos frequentes por episódios de angina instável, foi internada por angina aguda instável com bloqueio trifascicular e confirmação de ponte intramiocárdica no segmento médio distal da artéria descendente anterior. A otimização da terapêutica anti-isquémica foi baseada no carvedilol após implantação de pacemaker definitivo. Discussão: As pontes intramiocárdicas provocam uma redução dinâmica do lúmen do vaso epicárdico coronário e quando esta é superior a 50% provoca um fenómeno de ordenha, mais frequente nos segmentos médio e distal da artéria descendente anterior, a sua evolução é favorável e responde adequadamente à terapêutica com ß-bloqueantes. Conclusões: A correlação diagnóstica facilitou a aplicação de uma abordagem invasiva com estimulação transvenosa permanente, permitindo o início do tratamento com beta-bloqueadores, o que não teria sido possível devido ao distúrbio de condução intraventricular.

Nutcracker syndrome: a review

Left renal vein (LRV) entrapment is an anatomic condition characterized by extrinsic compression of the renal vein and consequent impaired inferior vena cava (IVC) outflow. Nutcracker syndrome (NCS) can be caused by compression of the LRV between the aorta and the superior mesenteric artery or by compression of LRV between vertebral bodies and the aorta. The most common presentations in NS include pelvic or left flank pain, hematuria, gonadal varices, thus the hallmark manifestations of NCS may be related to renal venous congestion and increased pressure within the venous structures. Computed tomography, magnetic resonance imaging and doppler ultrasonography are reasonable imaging studies in patients with suspected NCS, but invasive evaluation with catheter venography and pressure measurement is often required to the definitive diagnosis. For now, it is not possible to standardize a treatment modality, although the trend towards endovascular management is clear; therapeutic strategies with open surgery should not be lost for those cases that correspond to this.

No reflow phenomenon in CAD patients after percutaneous coronary intervention: A prospective hospital based observational study

The present study assessed incidence, risk factors, in-hospital and short-term outcomes associated with no-reflow in patients undergoing percutaneous coronary intervention (PCI) in STEMI, NSTEMI, unstable angina and stable angina. Out of 449 patients, 42 (9.3%) developed no-reflow. Hypertension, dyslipidemia, obesity and smoking were significant risk factors. There was significant association of no-reflow with left main disease, multiple stents, target lesion length_x0001_ 20 mm and higher thrombus grade. Interestingly, 93 patients (23.4%) of normal flow had myocardial perfusion grade (MPG) of 0/1 with mortality in 9 (10%) patients. No-reflow is associated with poor in-hospital and short-term outcomes with higher incidence of death, cardiogenic shock, heart failure and MACE. Knowledge of risk factors of no-reflow portends a more meticulous approach to improve final outcomes. MPG could be better predictor of outcomes in these patients.

Intervenciones quirúrgicas mínimamente invasivas complementarias a la ortodoncia quirúrgicamente asistida: Resumen estructurado de evidencia / Minimally Invasive Surgical Interventions Complementary to surgically assisted orthodontics: Structured summary of evidence

Introducción: Existen procedimientos quirúrgicos que pueden generar una disminución en la duración de los tratamientos de ortodoncia (TO) mediante una aceleración del movimiento dental. La técnica más estudiada corresponde a la corticotomía clásica, la cual muchas veces es desechada por los pacientes debido a su invasividad. Es por esto que nacen las intervenciones quirúrgicas mínimamente invasivas (IQMI), tales como las micro osteoperforaciones (MOP) y la piezocisión, que buscan el mismo resultado, pero sin realizar colgajos de espesor total, otorgándole al paciente nuevas alternativas terapéuticas para acortar el tratamiento de ortodoncia. La evidencia al respecto aún es controversial, debido a que la certeza de la evidencia es baja o muy baja con relación a estos procedimientos. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metaanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos 39 revisiones sistemáticas que en conjunto incluyeron 43 estudios primarios, de los cuales, 31 corresponden a ensayos aleatorizados. Concluimos que las intervenciones quirúrgicas mínimamente invasivas podrían aumentar la tasa de movimiento dental a las 12 semanas, la distancia total acumulada, la tasa de movimiento dental y reducir la duración total de tratamiento, pero la certeza de la evidencia es incierta. Además, podrían resultar en poca o ninguna diferencia sobre el índice gingival, la profundidad de sondaje y el índice de placa.

Introduction: There are surgical procedures that can generate a decrease in the orthodontic (OT) treatments duration through a Acceleration of tooth movement. The most studied technique corresponds to classical corticotomy, which is often discarded by patients due to its invasiveness. This is why minimally invasive surgical interventions (MISI) are born, such as micro osteoperforations (MOP) and piezocision, which seek the same result, but without making total thickness flaps, giving the patient new therapeutic alternatives to shorten orthodontic treatment. The evidence on this is still controversial, because the certainty of the evidence is low or very low in relation to these procedures. Methods: A search was performed using Epistemonikos, the biggest database for systematic reviews in health, which is maintained by screening of multiple sources of information, including MEDLINE, EMBASE, Cochrane, among others. Data from systematic reviews were extracted, and analysis of the primary studies was performed, including a meta-analysis and a summary of findings table using GRADE approach. Results and conclusions: We identified 39 systematic reviews that together included 43 primary studies, of which 31 correspond to randomized clinical trials. We conclude that minimally invasive surgical interventions could increase the rate of tooth movement at 12 weeks, distance total accumulated, the rate of tooth movement and reduce the total duration of treatment, but the certainty of the evidence is uncertain. In addition, they could result in little or no difference in gingival index, probing depth and plaque index.

Slow-flow phenomenon after drug-coated balloon angioplasty for lower-extremity arteries is associated with lack of prescribing of calcium channel blockers

This study aimed to investigate the relationship between prescription drugs and the slow-flow phenomenon after drug-coated balloon angioplasty. Of 30 patients, five (17%) presented with the slow-flow phenomenon. Patients with the slow-flow phenomenon were significantly less commonly prescribed calcium channel blockers than those without the slow-flow phenomenon (P ¼ 0.03). There was no intergroup difference in the prescription of angiotensin II receptor blockers and b-blockers. The clinical outcomes, including restenosis, thrombosis, target lesion revascularization, and death, did not differ between groups during the 10-month observation period.

Research progress of no-reflow phenomenon after revascularization in acute ischemic stroke / 临床神经病学杂志

Intravenous thrombolysis and revascularization in the time window are effective in promoting blood flow recanalization,reducing core infarction area and improving clinical prognosis in acute ischemic stroke(AIS).However,successful vascular recanalization does not mean the complete recovery of cerebral microcirculation perfusion,and the microstructure damage during ischemia may lead to microcirculation"no-reflow phenomenon(NRP)".In recent years,studies have found that about 40%of patients with AIS can have NRP after vascular recanalization,which is one of the important reasons for futile recanalization after vascular therapy in AIS.Therefore,early identification and treatment of NRP after recanalization treatment of AIS is of great significance to improve the prognosis.This article reviews the related definition,pathophysiological mechanism,imaging features and treatment strategies of NRP after vascular recanalization in AIS,in order to provide a reference for clinical diagnosis and treatment after vascular recanalization in AIS.

Correlation analysis of self-esteem and imposter phenomenon among clinical nurses / 中国实用护理杂志

Objective:To investigate the correlation relationship between self-esteem and imposter phenomenon among nurses,and to provide reference for optimizing nurse team.Methods:A total of 836 nurses were selected from February to March 2023 in the Yongzhou Central Hospital of Hunan Province and the People′s Hospital of Longhua, Shenzhen. A cross-sectional survey was conducted on nurses using the General Data Questionnaire, Impostor Phenomenon Scale and Self-Esteem Scale.Results:The imposter phenomenon score of nurses was (48.97 ± 12.58) points and the self-esteem score was (28.93 ± 3.86) points. The total score of self-esteem was negatively correlated with the total score of imposter phenomenon ( r= -0.433, P<0.01). Multivariate linear regression analysis showed that with the increase of self-esteem score, the score of imposter phenomenon decreased ( B=-1.402, P<0.01). Self-esteem was an important factor affecting the imposter phenomenon among clinical nurses, accounting for 18.9% of the total variation. Conclusions:The self-esteem and imposter phenomenon of clinical nurses are both at a moderate level, the improvement of self-esteem is beneficial to decreased their imposter phenomenon.

Two-dimensional speckle tracking echocardiography for evaluating the effect of enhanced external counterpulsation on left ventricular function in elderly patients with coronary slow flow phenomenon / 中华老年医学杂志

Objective:This study aimed to evaluate the effect of enhanced external counterpulsation(EECP)on left ventricular function in elderly patients with coronary slow flow phenomenon(CSFP)using two-dimensional speckle tracking echocardiography(2D-STE).Methods:This prospective case-control study included 30 patients aged ≥60 years with no stenotic lesions in the coronary arteries but with slow blood flow phenomenon in more than one major coronary artery who were treated at the Department of Geriatrics, Qilu Hospital, Shandong University, between December 2017 and December 2018, and were divided into a medication group with 16 participants and a medication plus EECP group with 14 participants, using the numerical lottery method.Patients in the group treated with EECP received 6-week 36-h EECP therapy in addition to lifestyle modification and drug treatment.Fourteen patients with normal coronary blood flow served as the control group.Conventional echocardiography and 2D-STE were used to evaluate changes in left ventricular function in the CSF patients before and after drug treatment and EECP.Results:Compared with the control group before treatment, patients in the drug treatment group and the drug treatment plus EECP group showed a decrease in mitral annular early diastolic velocity( P<0.01), an increase in the ratio of peak mitral early diastolic blood flow velocity to the mean peak mitral annular early diastolic velocity( P<0.05), and a decrease in left ventricular longitudinal strain during systole( P<0.01), the longitudinal systolic myocardial strain rate( P<0.01)and the early diastolic longitudinal peak strain rate( P<0.01).There was no statistically significant difference in values from conventional echocardiographic parameters before and after treatment in CSF patients of the medication group(all P>0.05).In the group receiving EECP, there were statistically significant differences in pre-and post-treatment values in ventricular septal early diastolic velocity[(6.22 ± 0.64)cm/s vs.(6.69 ± 0.44)cm/s], lateral wall early diastolic velocity[(8.01±0.68)cm/s vs.(8.41±0.29)cm/s], mitral valve to mitral annulus early diastolic peak velocity ratio[(10.51±1.38) vs.(9.74±0.37)], longitudinal left ventricular systolic strain[(-16.21±0.46)% vs.(-16.80±0.48)%], left ventricular systolic longitudinal strain rate[(-1.29±0.03)s -1vs.(-1.35±0.04)s -1], and early diastolic longitudinal strain rate[(1.35±0.03)s -1vs.(1.40±0.03)s -1](t-values were -3.70、-2.74、2.23、10.25、12.30、-19.15, all P<0.05). Conclusions:2D-STE can evaluate subclinical myocardial dysfunction early and quantitatively in elderly patients with CSF, and objectively reflect changes in left ventricular function before and after clinical intervention with EECP.

Analysis on the Phenomenon and Regularity of Acupoint Sensitization for Major Depressive Disorder / 浙江中医药大学学报

[Objective]To explore the phenomenon and regularity of acupoint sensitization for major depressive disorder(MDD)based on bibliometric methodology and data mining technology,and to provide scientific ideas for the clinical diagnosis and treatment of MDD.[Methods]Eight electronic databases and one ancient book were comprehensively searched and available literature was retrieved.Bibliometric methodology and data mining technology were applied to summarize the phenomenon and regularity of acupoint sensitization for MDD,and to explore the related theoretical mechanisms.[Results]A total of 29 literature related to acupoint sensitization of MDD was included.Acupoint sensitization of MDD involved in multiple forms,including heat sensitization,chemical sensitization,pain sensitization,and so on,and the testing means were diverse.The most common sensitized acupoint was Baihui(GV20).Among these acupoints,sensitization often simultaneously occurred in Baihui(GV20)and Neiguan(PC7),Baihui(GV20)and Taichong(LR3).The acupoints and sensitization could be divided into 4 effective clusters.The meridian involved with high sensitization frequency was governor vessel.Sensitization mainly occurred in the head-face-neck area.[Conclusion]The sensitization phenomenon of MDD has many types,However,there are few related studies at present.The phenomenon of acupoint sensitization involving acupoint,meridians,and location are relatively broad.There might be a close relationship between high-frequency sensitized acupoints and common acupoints for clinical treatment,which may be related to the effect of different acupoints and the etiology and pathogenesis of MDD.
