Relationship Between Symptom Distress,Functional Status and Quality of Life in Patients with Low Back Myofascial Pain Syndrome

Objective:To explore the relationship between symptomatic functional status and quality of life of patients with low back myofascial pain syndrome(MPS).Methods:From July 2021 to June 2022,106 patients with low back myofascial pain syndrome in the Affiliated Hospital of Hebei University were selected as the research subjects.A total of 106 MPS patients were investigated with general information questionnaire,Memory Symptom Assessment Scale(MSAS),Oswestry Disability Index(ODI)and Short Form Questionnaire(SF-36).The relationship between quality of life and symptom distress and dysfunction was observed and analyzed based on symptom distress and dysfunction scores,SF-36 scores,and so on.Results:The total score of MSAS was 1.79±0.91.The overall symptom distress of the patients was moderate.The ODI score was 18.46±5.95.The functional disability of the patients was classified as moderately impaired.The MSAS-PHYS,MSAS-PSYCH,MSAS-GDI three scale scores were 2.14±0.75,1.69±0.88,1.55±0.46,respectively,and the variability of the three scales is relatively large;the dimension scores were significantly lower than those of the conventional scoring models,and P<0.05,indicating a statistical difference;the scores of each dimension of the patient’s quality of life were compared with the scores of symptom distress and functional status.The higher the symptom distress score,the lower the quality of life,with P<0.05,indicating a statistical difference;the higher the score of each dimension of functional status,the better the quality of life,showing a positive correlation,and P<0.05,indicating a statistical difference.Conclusion:MPS patients face a number of physical and psychological symptoms,and their functional status is limited.Nursing staff should implement health education and intervention measures according to the actual situation of the patients,so as to improve the quality of their lives.

Effects of main active components of rosemary on growth performance,meat quality and lipid metabolism in finishing pigs

Rosemary extracts have been widely used as feed additives in recent years.This study aimed to investigate the effects of rosmarinic acid(RA)and ursolic acid(UA),the main active components of rosemary,on growth performance,meat quality and lipid metabolism in finishing pigs.A total of 72 finishing pigs(Landrace;initial age of 150 d)were randomly divided into 3 treatments with 8 replicates of 3 pigs each,and fed a basal diet or diet containing 500 mg/kg of RA or UA.The results showed that dietary supplementation of RA or UA had no significant effect on the growth performance and carcass traits of finishing pigs(P>0.05).However,both RA and UA significantly increased the triglyceride(TG)level in soleus muscle(P<0.001).Supplementation of RA increased the expression of genes related to lipogenesis and transport including fatty acid synthase(FAS)(P<0.001),sterol regulatory element binding protein-1c(SREBP1c)(P<0.001)and peroxisome proliferator-activated receptorγ(PPARγ)(P<0.05),while UA increased the expression of fatty acid transport protein 1(FATP1),a gene related to lipid uptake(P<0.05).However,RA reduced the expression of adipogenesis-related gene acetyl-coenzyme A carboxylase a(ACCa)(P<0.01).Characterization of cecal microbiota indicated that RA increased the microbial richness(chao 1,P<0.001)and diversity(observed species,P<0.01).Further analysis of the genera revealed that RA increased the relative abundance of Bacteroides and g-UCG-005(P<0.05),and UA enriched Prevotella(P<0.001).Correlation analysis showed that g-UCG-005 was positively correlated with the expression of FAS,carnitine palmitoyl transferase 1B(CPT1B),SREBP1c and PPARγ(P<0.01).In conclusion,dietary supplementation of RA or UA may increase fat deposition in muscle of finishing pigs by regulating lipid metabolism and gut microbiota.
