Objective To observe the value of diffusion-weighted imaging(DWI)parameters for evaluating grade of gliomas.Methods Totally 116 patients with glioma were retrospectively enrolled and divided into low-grade group(Ⅰ—Ⅱ,n=66)and high-grade group(Ⅲ—Ⅳ,n=50)according to 2000 WHO tumor grading criteria.Clinical and DWI data,including Ki-67 labeling index(LI),apparent diffusion coefficient(ADC),exponential ADC(EADC)and relative ADC(rADC)were compared between groups.The correlations of ADC,EADC and rADC with Ki-67 LI were explored,and the efficacy of above indexes for evaluating grade of glioma was analyzed.Results Significant differences of Ki-67 LI,ADC,EADC and rADC were found between groups(all P＜0.05).ADC and rADC of glioma were negatively correlated(r=-0.565,-0.625,both P＜0.05),while EADC was positively correlated with Ki-67 LI(r=0.587,P＜0.05).ADC,EADC,rADC and Ki-67 LI were all impact factors of grade of glioma(all P＜0.05),with the area under the curve of 0.768,0.802,0.788 and 0.793,respectively,and AUC of the combination of the four was 0.874,significantly higher than each index alone(all P＜0.05).Conclusion ADC,EADC and rADC were helpful for evaluating grade of glioma.Combining with Ki-67 LI could further improve diagnostic efficacy.

Objective This research aims to investigate the impact of Orff music therapy on long-term schizophrenic patients in hospitals.Methods The study was a randomized,single-blind controlled trial conducted from April,2023 to September,2023.From April to September 2023,sixty-eight individuals diagnosed with persistent schizophrenia were enrolled and evenly distributed into a pair of cohorts:a treatment group of thirty-four people receiving the intervention,and an equal number forming the control group for comparative purposes.Individuals enrolled in the experimental arm of the study were administered Orff-music therapy alongside routine rehabilitation treatment across a span of two months.For a period of 8 weeks,the control group was given only standard rehabilitation treatment,whereas the research group underwent Orff-music therapy in addition to the standard rehabilitation treatment.Results Before treatment,there were no significant differences in the positive and negative symptoms scale(PANSS),the inpatient psychosis rehabilitation observe scale(IPROS)and the personal and social performance scale(psp)between two groups.After intervention,the PANSS showed that the changes were better in the study group than in the control group in 3 indicators:negative symptoms(-3.20±4.13 vs.-0.17±2.43,P<0.001),general symptoms(-2.79±3.83 vs.-0.17±2.99,P=0.003)and the total scores(-5.88±6.36 vs.0.00±4.08,P<0.001),but not in positive symptoms(P>0.05).The IPROS showed that the performances of patients in the study group were better than the control group in terms of participation in work therapy(-0.82±2.08 vs.0.23±2.10,P=0.041),socialization(-0.59±1.94 vs.0.53±1.69,P=0.014)and ability to live(-0.94±2.50 vs.0.15±1.48,P=0.033),the changes in scores before and after the intervention were significantly different when compared to the control group.The PSP showed that the changes in scores before and after the treatment of the study group was better than the control group in terms of social activity[0(-1,0)vs.0(0,0),P=0.011],and self-care[0(-1,0)vs.0(-0.25,0),P=0.012]were better than the control group.Conclusion For long-term hospitalized patients with chronic schizophrenia.Orff-music therapy can be a powerful tool for alleviating mental issues,fostering social functioning,and enhancing rehabilitation results.

Objective To study the effect of ursolic acid (UA) intervention on hepatocyte apoptosis induced by TGF-β1 and its potential mechanism.Methods Primary hepatocytes were extracted from healthy SD rats by in situ perfusion,cultured for 12-24h,then randomly divided into the following groups:blank control group,UA control group (UA 25μmol/L),TGF-β1 group (TGF-β1 2.5ng/ml),UA intervention group (UA 25μmol/L and TGF-β1 2.5ng/ml),DPI intervention group (DPI 0.5μmol/L and TGF-β1 2.5ng/ml).Each group was treated with drugs for corresponding time and their proliferation and apoptosis were detected by flow cytometry,the expression of CD95 (Fas) mRNA was analyzed by RT-qPCR,the expression of protein CD95 and membrane translocation of NADPH oxidase (NOX) subunit p47Phox were analyzed by Western blotting,and the reactive oxygen species (ROS) generation in primary hepatocytes was analyzed with reactive oxygen detection kit.Results UA intervention at 30min before TGF-β1 stimulating hepatocytes markedly reduced hepatocyte apoptosis (63.97 ± 3.19 vs 80.53 ± 1.56,P＜0.01) and promoted hepatocyte proliferation (18.67 ± 1.60 vs 10.83 ± 2.03,P＜0.01).UA intervention notably down-regulated the expressions of CD95 mRNA and protein (1.28 ± 0.15 vs 2.40 ± 0.25,P＜0.01;1.05 ± 0.15 vs 1.37 ± 0.18,P＜0.05),restrained membrane translocation of p47phox (1.13 ± 0.12 vs 1.76 ± 0.22,P＜0.01),and decreased ROS level in primary hepatocytes induced by TGF-β1 (2.12 ± 0.45 vs 3.23 ± 0.53,P＜0.01).Conclusion The mechanism of UA inhibiting hepatocyte apoptosis induced by TGF-β1 is likely to be that UA intervention reduced hepatocyte apoptosis by inhibiting NOX activation and decrease generation of ROS so as to down-regulate expression of CD95 in hepatocytes.

OBJECTIVE: To analyze the clinical features of severe acute pancreatitis (SAP) in aged patients, and to explore the measures of its diagnosis and treatment. METHODS: The clinical data of 100 aged patients (55-85 years old) with SAP admitted from January 2003 to December 2005 were reviewed and compared with those of 221 non-aged SAP patients (11-54 years old) admitted at the same period. RESULTS: Totally 112 times of onset occurred in 100 aged patients, and the main causes for senile SAP were biliary diseases and hyperlipemia. Both acute physiology and chronic health evaluation II (APACHE II) and Ranson scores of the aged patients with SAP were higher than those of the control group (P<0.05); while there was no significant difference in Balthazar score between the two groups(P>0.05). The incidences of low serum calcium, low albumin and high aspartate aminotransferase (P<0.05), liver, kidney or brain impairment as well as the mortality were higher in the senile SAP group than those in the control group (P<0.05). CONCLUSIONS: Biliary disease and hyperlipemia are the main causes of senile SAP, which lacks characteristic clinical symptoms and is often associated with multiple complications such as infection and lung, gastrointestinal tract, liver, kidney, and brain impairment. Individualized differential treatment with integrated traditional Chinese and Western medicine based on stage classification is an effective approach.
