Cerebral palsy (CP) is a group of syndrome caused by a non-progressive brain injury that occurs from before birth to 28 days after birth. The principal symptoms of CP are abnormal centrocinesia and irregular posture, or accompanied by intelligence disorders, seizures, dystropy, sensory impairments and other dysfunctions. To evaluate the function of children with cerebral palsy can assess disfuction level,judge clinical classification, estimate prognosis, and more importantly guide to establish treatment plan and evaluate therapeutic efficacy. At present, there are no unified standards to evaluate CP at home and abroad, So this article will overview evaluation methods of CP commonly used in recent years.

Objective To observe the influence of the insulation blanket applied in general anesthesia on the incidence of postoperative delirium.Methods 60 patients with elective laparoscopic cholecystectomy under generalanesthesia with ASA of grade Ⅰ-Ⅱ were selected.According to the random number table,the patients were divided into group A(without insulation blanket)and group B (with insulation blanket),each group in 30cases.The dosage and drug batch number of anesthetic drugs were same.Evaluated each patient using the confusion assessment method-chinese revised (CAM-CR).Recorded the number of cases of delirium for each group when 24 hours,48 hours, 72 hours after operation.Results The incidence of postoperative delirium in group A was 6.7%,which in group B was 0.0%.The incidence of postoperative delirium of group B was lower than group A (P <0.05 ).Conclusion Using insulation blanket to protect body temperature in perioperative operation can reduce the incidence of postopera-tive delirium in perioperative operation.

Objective To explore the protective effect of bone marrow mesenchymal stem cells (MSC) on diabetic myocardium and anoxic pre-conditioning (AP).Methods Eight-week-- old male Sprague-Dawley rats were given with a single intraperitoneal injection of streptozotocin (STZ) (60 mg/kg)to induce diabetes mellitus (DM).Donor rats were 8-week-old male Sprague - Dawley rats.Before transplantation,MSC were incubated in CM-DiI at a concentration of 2 μg/mL for 20 min.AP-MSC were exposed to 3 hours of anoxia.At 4 months after STZ injection,diabetic rats were randomly given with an intramyocardial injection of one of the followings:150 μL of Dulbecco's modified Eagle's medium ( DMEM),5 ×106 MSC/150 μL,or 5 × 106 AP - MSC/150 μL (n =10 for each group).Three months after STZ injection and 2 weeks after transplantation,we evaluated the cardiac function by echocardiography,and also evaluated the cardiac conditions by alkaline phosphatase staining,western blot analysis for apoptosis related proteins and signal pathways.Results MSC,especially AP- MSC increased fractional shortening (FS) of diabetic heart (P ＜0.01 vs DMEM respectively).AP-MSC greatly increased the capillary density of diabetic myocardium (P ＜0.01 vs DMEM and MSC group respectively).AP-MSC are anti-apoptotic in the rat DCM model,possibly mediated through cardiac upregulation of Bcl-2/Bax ratio ( P ＜ 0.05 ) and inhibiting the expression and activation of caspase - 3 ( P ＜ 0.01 ).Conclusions Intramyocardial transplantation of APMSC has a protective effect on diabetic cardiomyopathy.

Objective:To evaluate the efficacy and safety of acupuncture-moxibustion in the treatment of cerebral palsy-related speech impairment.Methods:A systematic literature search of 7 electronic databases was conducted between January 7,2000 and January 12,2021 to find randomized controlled trials(RCTs)examining the benefits of acupuncture-moxibustion combined with rehabilitation training to cerebral palsy-induced speech impairment.The included trials'quality was assessed using the Cochrane Reviewers'Handbook as a guide,and statistical analysis was carried out using the RevMan 5.3 software.Results:A total of 17 RCTs with 1238 subjects were finally recruited and analyzed.When acupuncture-moxibustion was combined with rehabilitation training,the results showed a considerable improvement in speech impairment compared with the rehabilitation training alone.The most commonly used points for the treatment of speech disorders are Baihui(GV20),Speech Area,Zhisanzhen[Shenting(GV24)and bilateral Benshen(GB13)],Niesanzhen[2 Cun above the ear tip as the first point,with 1.0 Cun anterior and posterior to the current point as the second and third points],and Sishenzhen[1.5 Cun anterior,posterior,and bilateral to Baihui(GV20)].Conclusion:Acupuncture-moxibustion has a stronger effect on children's development of receptive and expressive language,as well as the developmental quotient.Acupuncture-moxibustion in combination with rehabilitation training is not only more successful than the control treatment,but also safer and more dependable.Baihui(GV20),Speech Area,Zhisanzhen,Niesanzhen,and Sishenzhen are the most widely used points for speech impediment.

To investigate the therapeutic effect of peroxiredoxin-6(PRDX6)on ultraviolet-induced corneal injury in rats and explore the mechanism.The rat model of corneal injury was established by exposing to ultravio-let.Male wister rats were randomly divided into control groups,dexamethasone (DXM)groups and PRDX6 groups,the rats were administered four times a day and for 12 days.The corneal opacity was observed with a slit-lamp microscope.Histopathologic changes were observed with light microscopy.The content of corneal malonalde-hyde(MDA)was determined by thiobarbituric acid test and the total antioxidative capacity(TAOC)was detected by chemical colorimetric test.P38 MAPK signal pathway was detected with the method of Western blot and the gene expression of cytokines were measured by RT-PCR method.Compared with the control group,PRDX6 treat-ment significantly reduced corneal opacity,improved corneal pathology injury,decreased the MDA content and in-creased the TAOC.In the PRDX6 group the level of phosphorylated p38 protein was significantly lower than that in the control group.The gene expression of cytokine were different between control and PRDX6 groups(P <0.05).PRDX6 showed therapeutic effect in the rat model of ultraviolet-induced corneal injury.This maybe be concerned with that it could alleviated the oxidative damage,suppressed p38 MAPK phosphorylation and regulate the gene expression of cytokine.

Objective:To explore the lactate metabolism in brain tissue of the mice with early acute hypoxia-ischemia injury,and to provide data support for 9.4T 1 H-NMR spectroscopy in detecting the lactate level clinically.Methods:Eighty Kunming mice were randomly divided into sixteen groups (0 s,20 s,40 s,60 s,2 min,4 min, 6 min,8 min, 10 min, 12 min, 14 min, 16 min, 18 min,and 20 min)according to the duration of hypoxia-ischemia (n=5).The changes of lactate levels were detected by 9.4T 1 H-NMR spectroscopy. Results:After the initiation of hypoxia-ischemia injury,the lactate level began to increase rapidly to the highest value of (6.89 ± 0.34)μmol·g-1 at 20 s,then started to decline quickly from 40 s to 2 min,and eventually decreased to a stable level of (4.85±0.36)μmol·g-1 until 6 min.Compared with control group,the levels of lactate in brain tissue of the mice in hypoxic-ischemic groups were increased (P <0.01).Conclusion:40 s of acute hypoxia-ischemia may be the lactate cerebral neuron threshold during the anaerobic glycolysis. 9.4T1 H-MRS can provide the exact time window for detecting the lactate metabolism.

Background and purpose: MORC2 (microrchidia family CW-type zinc finger 2, MORC2) is a newly identified chromatin remodeling protein that plays key roles in DNA-based biological processes including gene transcription and DNA damage repair. However, its functional role in breast cancer development and progression re-mains unknown. ALDH1A3 (aldehyde dehydrogenase 1 family member A3), a member of the aldehyde dehydrogenases (ALDH) superfamily, is a putative breast cancer stem cell marker, but its regulatory mechanism in breast cancer is poor-ly characterized. This study aimed to investigate the effects of knockdown of endogenous MORC2 on the expression levels of ALDH1A3 and the breast cancer stem-like phenotype in MCF-7 cells. Methods: Human breast cancer MCF-7 cells were infected with negative control short hairpin RNAs (shNC) and specific shRNAs targeting human MORC2 (shMORC2), followed by selection with puromycin to generate stable MORC2 gene knockdown cell lines. Western blot and real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) were used to examine the protein and mRNA levels of ALDH1A3 in MCF-7 cells stably expressing shNC and shMORC2. Microsphere formation and fluo-rescence-activated cell sorting (FACS) assays were used to analyze the effects of knockdown of MORC2 on the breast cancer stem-like phenotype. Results: Western blot and RTFQ-PCR analyses revealed that the protein and mRNA levels of ALDH1A3 were significantly down-regulated in shMORC2 expressing cells as compared with shNC -transfected control cells. Moreover, mammosphere formation assay showed that knockdown of endogenous MORC2 in MCF-7 cells significantly reduced the ability of cells to form microspheres. Consistently, FACS assays demonstrated that shMORC2-transfected cells had a lower proportion of ALDH-positive stem cells as compared with shNC expressing cells. In contrast, knockdown of MORC2 did not significantly affect the CD44+CD24- stem cell population. Conclusion:MORC2 promotes a breast cancer stem-like phenotype through, at least in part, regulating ALDH1A3 expression.
