An overview of acupuncture for the treatment of limb spasticity in cerebral palsy-A mini review

Cerebral palsy is a common chronic disabling disease in children with special needs,and rehabilitation for cerebral palsy is characterized by a long period,multiple methods and limited efficacy.Due to the limited motor function of cerebral palsy patients,the quality of life of patients is reduced,and their ability to participate in society is reduced,so the improvement of patients’motor function has become an important goal of cerebral palsy rehabilitation.The motor function of cerebral palsy has become an important goal of cerebral palsy rehabilitation.Limb spasticity is one of the main clinical signs of cerebral palsy patients,and the more severe the limb spasticity is,the greater the impact on the patient's motor function,so improving limb spasticity in patients with cerebral palsy is particularly important.Acupuncture,as a Chinese medicine treatment method,has been widely used in the clinical treatment of cerebral palsy in China,and has shown certain efficacy.To promote the clinical application of acupuncture technique in cerebral palsy limb spasticity,this paper analyses and summarizes the relevant literature on acupuncture treatment of cerebral palsy limb spasticity summarizes the current status of the clinical application of acupuncture in cerebral palsy limb spasticity,and provides clinical references for the reasonable application of acupuncture in cerebral palsy limb spasticity.

Research progress regarding the nutritional status and assessment methods of cerebral palsy patients

Cerebral palsy is a group of clinical disorders characterized by persistent central motor deficits and postural abnormalities due to non-progressive damage to the fetal or infant brain.Malnutrition is one of the most common clinical comorbidities in children with cerebral palsy and is the result of a combination of internal factors,such as the child’s structural and functional abnormalities,and external factors,such as the child’s feeding habits and family/social factors.The nutritional status of children with cerebral palsy is closely related to their development,quality of life,social participation,and life expectancy;thus,an objective and accurate understanding of the nutritional status of these children through rehabilitation assessment is essential for their growth and development.The current nutritional assessments include routine measurements of human nutritional parameters,scale-based assessments,and instrumental assessments.It is important to detect malnutrition in children with cerebral palsy at an early stage,reduce the prevalence of malnutrition,and improve the quality of survival.Therefore,this review aimed to analyze and summarize the nutritional status and assessment methods of children with cerebral palsy,to assess the nutritional status of children with cerebral palsy from multiple perspectives,indicators and directions,and to provide reference for the early detection of co-morbid malnutrition in children with cerebral palsy.

Microstructure and thermal properties of copper matrix composites reinforced with titanium-coated graphite fibers

Milled form of mesophase pitch-based graphite fibers were coated with a titanium layer using chemical vapor deposition technique and Ti-coated graphite fiber/Cu composites were fabricated by hot-pressing sintering. The composites were characterized with X-ray diffraction, scanning/transmission electron microscopies, and by mea- suring thermal properties, including thermal conductivity and coefficient of thermal expansion （CTE）. The results show that the milled fibers are preferentially oriented in a plane perpendicular to the pressing direction, leading to anisotropic thermal properties of the composites. The Ti coating reacted with graphite fiber and formed a continuous and uniform TiC layer. This carbide layer establishes a good metallurgical interracial bonding in the composites, which can improve the thermal properties effectively. When the fiber content ranges from 35 vol% to 50 vol%, the in-plane thermal conductivities of the composites increase from 383 to 407 W.（m.K）-~, and the in-plane CTEs decrease from 9.5 x 10-6 to 6.3 10-6 K-1.

Real world effectiveness of PCSK-9 inhibitors combined with statins versus statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease in China(RWE-PCSK study)

BACKGROUND The efficacy and safety of proprotein convertase subtilisin/kexin type 9(PCSK-9) inhibitors were confirmed by several clinical trials, but its effectiveness in routine clinical practice in China has not been evaluated. This study aims to describe the real world effectiveness of PCSK-9 inhibitors combined with statins compared with statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease(ASCVD).METHODS This is a multi-center observational study, enrolled patients from 32 hospitals who underwent percutaneous coronary intervention(PCI) from January to June in 2019. There are 453 patients treated with PCSK-9 inhibitors combined with statins in PCSK-9 inhibitor group and 2,610 patients treated with statins-based lipid lowering therapies in statins-based group. The lipid control rate and incidence of major adverse cardiovascular events(MACE) over six months were compared between two groups.A propensity score-matched(PSM) analysis was used to balance two groups on confounding factors. Survival analysis using Kaplan-Meier methods was applied for MACE.RESULTS In a total of 3,063 patients, 89.91% of patients had received moderate or high-intensity statins-based therapy before PCI, but only 9.47% of patients had low-density lipoprotein cholesterol(LDL-C) levels below 1.4 mmol/L at baseline. In the PSM selected patients, LDL-C level was reduced by 42.57% in PCSK-9 inhibitor group and 30.81%(P < 0.001) in statins-based group after six months. The proportion of LDL-C ≤ 1.0 mmol/L increased from 5.29% to 29.26% in PCSK-9 inhibitor group and 0.23% to 6.11% in statins-based group, and the proportion of LDL-C ≤ 1.4 mmol/L increased from 10.36% to 47.69% in PCSK-9 inhibitor group and 2.99% to 18.43% in statins-based group(P < 0.001 for both). There was no significant difference between PCSK-9 inhibitor and statins-based treatment in reducing the risk of MACE(hazard ratio = 2.52, 95% CI: 0.49-12.97, P = 0.250).CONCLUSIONS In the real world, PCSK-9 inhibitors combined with statins could significantly reduce LDL-C levels among patients with very high risk of ASCVD in China. The long-term clinical benefits for patients received PCSK-9 inhibitor to reduce the risk of MACE is still unclear and requires further study.

Distributed optimization for discrete-time multiagent systems with nonconvex control input constraints and switching topologies

This paper addresses the distributed optimization problem of discrete-time multiagent systems with nonconvex control input constraints and switching topologies.We introduce a novel distributed optimization algorithm with a switching mechanism to guarantee that all agents eventually converge to an optimal solution point,while their control inputs are constrained in their own nonconvex region.It is worth noting that the mechanism is performed to tackle the coexistence of the nonconvex constraint operator and the optimization gradient term.Based on the dynamic transformation technique,the original nonlinear dynamic system is transformed into an equivalent one with a nonlinear error term.By utilizing the nonnegative matrix theory,it is shown that the optimization problem can be solved when the union of switching communication graphs is jointly strongly connected.Finally,a numerical simulation example is used to demonstrate the acquired theoretical results.

Influence of glucagon-like peptide 1 on the expression of ACAT1,CD36 gene and cholesterol metabolism in macrophages

Objective:To investigate whether glucagon like peptide-1(GLP-1)can reduce the cholesterol in foam cells derived from macrophages by affecting the expression of CD36 and acyl-CoA1(ACAT1)The content.Methods:Macrophages were obtained from mice,and after corresponding treatment,they were divided into 4 groups:blank control group,experimental group,GLP-1 agitation group,GLP-1 inhibition group,and the expression of CD36,ACAT1 mRNA and protein in cells of each group was detected.Expression and levels of total cholesterol(TC),free cholesterol(FC)and cholesterol ester(CE).Results:Compared with the blank control group,the content of TC,FC,CE and the expression of CD36,ACAT1 mRNA and protein in the experimental group were significantly increased(P<0.05);compared with the experimental group,the content and content of TC,FC,CE in the GLP-1 excited group The expressions of CD36 and ACAT1 mRNA and protein were significantly decreased(P<0.05);compared with the GLP-1 agitation group,the contents of TC,FC and CE and the expression of CD36,ACAT1 mRNA and protein were significantly increased in the GLP-1 inhibition group(P<0.05).Conclusion:The expression levels of CD36 and ACAT1 can be suppressed by GLP-1,and under the indirect influence of GPL-1,the level of intracellular cholesterol will also be reduced,so that the process of macrophages to foam cells is suppressed Thereby slowing down the development of atherosclerosis.

Evaluation of a new frequency-volume chart for children with primary monosymptomatic nocturnal enuresis:a prospective,comparative study

Introduction To improve compliance with voiding diaries in children with primary monosymptomatic nocturnal enuresis(PMNE),a new modified 3-day weekend frequency-volume chart(FVC)was designed,and the compliance and validity of this modified FVC was evaluated by comparing with the International Children's Continence Society(ICCS)recommended voiding diary.Methods A total of 1200 patients with PMNE were enrolled in the study from 13 centers in China and were randomly assigned to record this modified FVC or the ICCS-recommended voiding diary.The primary outcome measure was the compliance,assessed by comparing the completing index and the quality score of diaries between two groups.The secondary outcome measure was the validity,evaluated by comparing the constituent of subtypes,micturition parameters and response rate to desmopressin.Results Among the 1200 participants enrolled in the study,447 patients completed the ICCS-recommended voiding diary and 469 completed the modified diary.The diurnal completing index and the quality score of the modified FVC group were better than those of the ICCS group.In addition,there was no significant difference between these two groups in the subtype classification,or in the response rate to desmopressin.Conclusions The modified FVC could be applied to obtain the voiding characteristics of children with PMNE as the ICCS-recommended voiding diary does and offers a reasonable and better choice for children with PMNE from the unselected population in the future.
