Quantitative analysis on diffusion tensor imaging is prerequisite. The arithmetic of statistical analysis was reviewed in this article via analyzing the arithmetic of quantitative parameters and fiber track on diffusion tensor imaging.

Objective The lyophilized pilose antler water extract(PAE) was isolated,and their cell proliferation on PC12 cells was observed.Methods S-200 Size-exclusive gel and DEAE negative ion-exchange liquid chromatograph were employed to fractionate the PAE.SDS-PAGE was employed to analyze the proteins composition of PAE.The protein concentration was determined by Folin-Phenol assay.The proliferation rates of PC12 cells were measured by MTT assay.Results The proliferation rate of PAE on PC12 cells at 13.3 mg/mL was 47%(P

Objective To determine the effects of continuous θ burst stimulation of contralateral premotor areas on post-stroke spasticity gait in patients with severe hemiplegia.Methods A pro-spective trial was conducted on 186 stroke patients with severe hemiplegia admitted to our depart-ment from January 2019 to January 2024.They were randomly into control group(93 cases,con-ventional rehabilitation training)and observation group(93 cases,continuous θ burst transcranial stimulation).In 4 weeks after treatment,gait parameters,Fugl-Meyer assessment of lower ex-tremity(FMA-LE)score,Berg balance scale(BSS)score,clinic spasticity index(CSI)score,lower limb sensation,spasticity improvement,and total effective rate were compared between the two groups.Results After treatment,both the 2 groups had significantly higher hip flexion,knee flex-ion,stride length,step frequency,step speed,FMA-LE score,BSS score,CSI score,and H wave latency,and lower two-point discrimination perception and H/M ratio when compared with the levels before treatment(P＜0.01).What's more,all above indicators were obviously better in the observation group than the control group(P＜0.01).The observation group had 1(1.1％),11(11.8％),48(51.6％),31(33.3％)and 2 cases(2.2％),respectively,of spasticity improvement grades 1,1+,2,3,and 4,and the control group had 0,7(7.5％),29(31.2％),44(47.3％),and 13 cases(14.0％),respectively,with statistical differences between the two group(P＜0.01).The total effective rate was notably higher in the observation group than the control group(96.8％vs 77.4％,x2=15.500,P＜0.01).Conclusion For severe hemiplegia patients,continuous θ burst stimulation can improve muscle spasm,restore gait,and better improve lower limb sensory and motor function.

Objective To analyze the applied condition of ovary function suppression ( OFS) before and after joint analysis of TEXT and SOFT trials and SOFT trial, and to identify the relevant factors of OFS usage. Methods The analysis was performed in premenopausal women with hormone receptor ( HR ) positive breast cancer receiving surgical treatment from Apr 2013 to Oct 2015 in Ruijin Hospital, Shanghai Jiaotong University School of Medicine. Adjuvant treatment strategy was made in the multidisciplinary team ( MDT) meetings. We analyzed the applied condition of OFS before and after joint analysis, SOFT trial and its relevant factors. Results Among 454 patients, 114 (25.1%) patients received OFS. Before the results of joint analysis came out, all the patients ( 38/38) received OFS together with tamoxifen ( TAM);after the results came out, clinicians began to put OFS with exemestane into practice, among 76 patients, 41(53.9%) patients received OFS with exemestane while 35 (46.1%) patients received OFS together with TAM. Before the results of SOFT trial came out, 71 out of 310 (22.9%) patients received OFS while 43 out of 144 (29.9%) patients received OFS after that. No significant difference was found between the proportion of patients receiving OFS before and after the results of SOFT trial came out ( P=0.112) . Age, histological grade, pN status, Ki?67 status, molecular subtype and acceptance of chemotherapy were correlated with OFS treatment (P<0.05). Age, tumor grade and pN were independent significant predictors of OFS usage. Conclusions After the results of joint analysis came out, clinicians began to apply OFS with exemestane to premenopausal women with HR positive breast cancer. There is no significant difference between the proportion of patients receiving OFS before and after SOFT trial. Age, tumor grade and pN status are independent significant predictors of OFS treatment. Patients younger than 40, with histological grade Ⅱ or Ⅲ tumor and with pN1 or pN2 status are prone to receive OFS.
