ABSTRACT
ObjectiveTo identify potential distribution areas for wild Panax ginseng cultivated under forest in Liaoning province， China， and analyze the ecological factors of spatial stratified heterogeneity affecting its ecological suitability and quality suitability. MethodWild Panax ginseng samples cultivated under forest were collected from 33 cultivation bases in Liaoning province. The Maxent maximum entropy model and ArcGIS were used to delineate the ecological suitability zones. Correlation analysis was performed on seven indicators and 110 ecological factors. Variables with significant correlation （P<0.05） were used to build partial least squares regression analysis models. A comprehensive quality zoning was conducted using the analytic hierarchy process （AHP）. The geographic detector was employed to analyze the interactions among dominant ecological factors of spatial stratified heterogeneity affecting habitat suitability， quality suitability， and the ecological driving factors. ResultVegetation type was the most influential ecological factor for delineating the ecological suitability zones for wild Panax ginseng in Liaoning province. The main ecological suitability areas for wild Panax ginseng cultivated under forest were located in the northeast， east， and southeast regions along the line from Xifeng County to Gaizhou City. The comprehensive quality suitability of wild Panax ginseng cultivated under forest was highest in Kuandian County and Huanren County and gradually decreased to the northwest and southwest. Within the delineated regions， the suitability conditions and comprehensive quality of wild Panax ginseng cultivated under forest were primarily influenced by the interactions between radiation and precipitation factors. The content of the measured samples was significantly higher than the standards in the 2020 edition of the Chinese Pharmacopoeia， indicating the high overall quality of wild Panax ginseng in Liaoning Province. ConclusionAccording to the zoning and prediction results， areas in Fengcheng City， Xiuyan County， Zhuanghe City， Liaoyang County， Tieling County， Xifeng County， Gaizhou City， Haicheng City， and Dashiqiao City showed large potential distribution areas with high quality， making them highly promising for wild Panax ginseng cultivation. However， further experimental verification is required. The zoning results can provide insights for research on habitat suitability and comprehensive quality accumulation of wild Panax ginseng cultivated under forest， as well as guidance for the search for potential cultivation areas and industrial development of wild Panax ginseng in Liaoning Province.
ABSTRACT
A case of limb girdle muscular dystrophy type 2S (LGMD2S) caused by maternal uniparental disomy on chromosome 4 at the First Affiliated Hospital of Henan University of Chinese Medicine in March 2020 was reported.The female child, aged 9 months and 4 days, presented with developmental delay after bacterial meningitis in early infancy, decreased muscle strength in infancy and increased muscle and liver enzymes.Family genetic analysis showed that the child′s monodiploid in chromosome 4 was maternal origin, and the homozygous c. 1066T > G (p.Y356D) of TRAPPC11 gene may had pathogenic variation, which came from the child′s mother.The final diagnosis of LGMD2S was made according to the clinical manifestations and gene test results.LGMD2S is a rare autosomal recessive disease caused by the pathogenic variation of TRAPPC11 gene.Its clinical characteristics include proximal limb weakness, motor and intellectual retardation, seizures, motor disorders, elevated serum creatine kinase and muscular dystrophy like pathological changes in children.
ABSTRACT
Chinese rehabilitation guidelines for cerebral palsy (2022) mainly refers to the international evidence-based medicine and relevant guidelines for rehabilitation of cerebral palsy in recent five years.On the basis of the Chinese rehabilitation guidelines for cerebral palsy (2015), combined with the medical literature and research achievements published at home and abroad before June 2022, the evidence-based practice guidelines are revised by combining the common opinions of pediatric rehabilitation experts in China.The content includes introduction, overview, the assessment and intervention guideline for infants at high risk of cerebral palsy, evaluation of children with cerebral palsy under ICF-CY framework, rehabilitation treatment, Traditional Chinese Medicine rehabilitation therapy, rehabilitation nursing, rehabilitation approaches and management.This article interprets the guide in combination with the hot spots of cerebral palsy prevention and treatment at home and abroad, in order to help pediatric rehabilitation workers deepen their understanding of the guidelines and better guide the clinical rehabilitation practice.
ABSTRACT
Objective To observe the effects of Salvia injection on the brain pathology,expression of synaptophysin and the synaptic ultrastructure at different time points in neonatal rats after hypoxic-ischemic brain damage (HIBD).Methods One hundred and fifteen healthy newborn SD rats of 7-day-old were randomly divided into normal group,sham group,Salvia high dose group,Salvia low dose group,and the HIBD model group.The HIBD model was prepared by ligation of the left carotid artery combined with hypoxic environment.The rats(in normal group,sham and HIBD model groups) were injected with sterile saline[9.0 mL/(kg · d)],while the rats in high and low dose groups were injected with Salvia injection [9.0 mL/(kg · d) and 4.5 mL/(kg · d) respectively].The intraperitoneal injec tion lasted for 7 and 14 days.The rats' brains were collected at one day,7 days and 14 days after the modeling respec tively.The specimens of brain tissue were observed through hematoxylin-eosin (HE),the expression of synaptophysin (SYP) was determined by using immunohistochemistry method,and the synaptic ultrastructure in the frontal cortex was observed through transmission electron microscope.Results Finally,106 newborn rats were included in statistics analysial.(1)General observation:after HIBD modeling,the neonatal rats were mostly in the left-lateral position,with difficulties in turning over,balance abnormalities,limb shaking and other abnormal behaviors,and the delay of eyes open with the left upper eyelid ptosis.(2) Pathology:the disordered and deep stained nerve cells,the degenerated and necrotic neurons were observed in the brain tissues of the HIBD model group.(3) Expression of synaptophysin:mean density of SYP in the HIBD model group was significantly lower than the normal group on day 1,day 7,and day 14 (P ＜0.05);the SYP expression in the Salvia intervention groups increased compared with the HIBD model group(P ＜ 0.05).(4) Synaptic ultrastructure:the incomplete structure of the frontal cortex neurons,the swelling organelle and the synaptic structure damage were observed in the HIBD rats.Compared with the HIBD model group,the neuronic and synaptic ultrastructure were improved by the intervention treatment of high and low dose Salvia injection.Conclusions The mechanism of Salvia injection in treatment of neonatal rats with HIBD may be associated with the improvement in neuronal ultrastructure and synaptic reorganization.

ABSTRACT
@#Objective To observe the clinical effect of manipulation to Du channel and Jiaji acupoints on dyskinetic cerabral palsy.Methods 76 children with dyskinetic cerebral palsy were divided into control group (n=31) and treatment group (n=34). The control group received conventional therapy and the treatment group received the manipulation to Du channel and Jiaji acupoints in addition. Gross Motor Function Measure (GMFM), and the changes of reflection in lateral bending and muscle tension fluctuation were evaluated. Results There was no significant difference in the percentages of total GMFM, lateral bending reflex, and muscle tension fluctuation between 2 groups before treatment (P>0.05). After treatment, all these indexes were better in the treatment group than in the control group (P<0.05). Conclusion manipulation to Du Channel and Jiaji acupoints can promote the the lateral bending reflex disppear, reduce the fluctuation of musle tone, and improve the gross motor function.
ABSTRACT
@#Spasticity can influence the outcome of the patients with cerebral injury. Most traditional physical therapies often focused on the spastic muscle. The recent development has showed that stimulating the antagonistic muscle can relieve the spasticity, which based on the reciprocal inhibition theory. This paper reviewed these approaches on its theory and application.
