RESUMO
INTRODUCTION: Lumbopelvic pain (LPP) is common in pregnant women and has a significant negative effect on physical and psychological health. In this study, for the first time, we conduct a meta-analysis to estimate the overall prevalence of LPP among pregnant women and clarify the reasons for the differences in the estimated results. MATERIAL AND METHODS: A systematic search of four databases (PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials) was conducted from inception until October 2022. Two reviewers conducted a methodological quality assessment. Random-effects model analysis was used to estimate the pooled prevalence and the 95% confidence interval. Chi-square tests and I2 -values were used to assess the heterogeneity. Subgroup analysis (according to the participants' continent, age, body mass index [BMI], gestational age and study risk of bias), sensitivity analysis and random-effects meta-regression were used to explore the the sources of heterogeneity. RESULTS: Of the 1661 unique citations, 38 studies (21 533 pregnant participants) were included in this systematic review and meta-analysis. The overall pooled prevalence of LPP during pregnancy was 63% (95% CI: 0.57 to 0.69), with significant heterogeneity (I2 = 99.1%, P < 0.001). The prevalence differed by participants' continents, 71% (North America), 74% (South America), 63% (Asia), 64% (Europe), 59% (Africa) and 45% (Oceania). The prevalence differed by BMI, 64% (BMI <25), 64% (25 ≤ BMI ≤ 28), and 71% (BMI >28). The prevalence differed by age, 72% (age <25 years), 58% (25 ≤ age ≤ 30 years), and 69% (age >30 years). The prevalence were the same differed by study risk of bias, 63% (both low and moderate risk of bias studies). The prevalence were similar by gestational age, 62% (second trimester) and 63% (third trimester). CONCLUSIONS: Lumbopelvic pain during pregnancy is common; about three-fifths of pregnant women experience LPP. More prevention and intervention research for lumbopelvic should be conducted in pregnant women with different clinical characteristics.

The NLRP3 inflammasome's core and most specific protein, NLRP3, has a variety of functions in inflammation-driven diseases. Costunolide (COS) is the major active ingredient of the traditional Chinese medicinal herb Saussurea lappa and has anti-inflammatory activity, but the principal mechanism and molecular target of COS remain unclear. Here, we show that COS covalently binds to cysteine 598 in NACHT domain of NLRP3, altering the ATPase activity and assembly of NLRP3 inflammasome. We declare COS's great anti-inflammasome efficacy in macrophages and disease models of gouty arthritis and ulcerative colitis via inhibiting NLRP3 inflammasome activation. We also reveal that the α-methylene-γ-butyrolactone motif in sesquiterpene lactone is the certain active group in inhibiting NLRP3 activation. Taken together, NLRP3 is identified as a direct target of COS for its anti-inflammasome activity. COS, especially the α-methylene-γ-butyrolactone motif in COS structure, might be used to design and produce novel NLRP3 inhibitors as a lead compound.
RESUMO
Objective:To detect the changes in mental arithmetic competence and the related influencing factors in patients with early Parkinson's disease(PD)by using mental arithmetic task behavioral experiment.Methods:Thirty-one patients with early PD and 40 healthy controls were enrolled in this study.The cognitive functions were tested by mini-mental state examination(MMSE)and Montreal cognitive assessment(MoCA). The differences of mental arithmetic competence between the two groups were measured by behavioral experiment.Results:There was no significant difference in correct rate, reaction time and post-corrected reaction time while performing baseline tasks and easy mental arithmetic tasks between the two groups( P>0.05). The reaction time had no significant difference between the two groups after adjusting some confounding factors( P>0.05). However, the correct rate while performing difficult mental arithmetic tasks was significantly lower( t=-2.232, P=0.029)and the reaction time was significantly longer( t=2.149, P=0.035)in PD group than in the controls, and the significant difference in reaction time persisted even after adjusting some confounding factors( t=3.139, P=0.003). In PD group, the correct rate of difficult mental arithmetic tasks was positively associated with MoCA scores( r=0.561, P=0.004), and negatively associated with age( r=-0.532, P=0.008). The reaction time and post-corrected reaction time while performing difficult metal arithmetic task were negatively associated with MoCA scores( r=-0.525, P=0.01; r=-0.554, P=0.005)and positively associated with age( r=0.485, P=0.037; r=0.514, P=0.012)in PD group. Conclusions:The difficult mental arithmetic competence is impaired in early PD patients, which is statistically significantly correlated with cognitive function and age.

Objective To detect the impairment of response inhibition and working memory in patients with alcohol dependence.Methods A total of forty-eight alcohol dependent patients and fifty age,gender,IQ,education matched controls were recruited.Neuropsychological tests were applied to measure the differences of response inhibition and working memory between the two groups.Results In the response inhibition task,the patient group had more commission errors ((7.02± 3.48) vs (3.45± 1.52)) and longer reaction time ((605.45 ± 142.56)ms vs (435.72±51.18)ms) compared to the control group (t=6.534,P=0.000; t=7.781,P=0.000).In the spacial working memory task,the patient group also had more commission errors ((4.58± 3.45) vs (0.43± 0.88)) and longer reaction time((10566.16±2455.61) ms vs (9185.44±2677.52) ms) than control (t=8.085,P =0.000; t=2.657,P=0.009).Conclusion There are significant deficiencies in response inhibition and working memory in patients with alcohol dependence.
RESUMO
Objective To investigate the relationship between the cerebral microbleeds (CMBs) and changes of cognitive function,and the possible mechanism of cognitive impairment caused by CMBs.Methods Sixty-eight micro-hemorrhage patients on susceptibility weighted imagine (SWI) sequences composed positive group,and sixty-eight patients selected without micro-hemorrhage in the SWI sequence and meeting the selection criteria as control group.At the same time,both two groups were assessed by MoCA and CDT scale inspection.Results CDT scores of CMBs group (2.00±0.88) were significantly lower than those of control group (3.76±0.53),and there was significantly different in the two groups (t=-3.27,P=0.00).At the same time,MoCA total scores and executive functions,naming,calculation,language,abstraction,recall scores of CMBs group were significantly lower than those of control group,and all of the groups were significantly different (t=-5.48,P=0.00; t=-4.36,P=0.00; t=-2.35,P=0.01 ; t=-2.49,P=0.02; t=-4.09,P=0.00; t=-4.63,P=0.00).CDT scores,MoCA total scores,executive functions,language,abstraction,memory scores between CMBs groups and control group were significantly different at all levels (P＜0.05).Executive functions,languages and calculated inter-group of mild CMBs,moderate CMBs,severe CMBs were significantly different (P＜0.05).The number of CMBs was negative correlation with total scores,executive function,language,and abstract (r=-0.675,P=0.000; r=-0.689,P=0.000; r=-0.536,P=0.000; r=-0.636,P=0.000).Conclusion The existence of CMBs and the number of CMBs are closely related to cognitive dysfunction.The more of CMBs,the more of obvious cognitive impairment.
RESUMO
Objective To investigate the clinical effect of botulinum toxin type A (BTX-A) injections guided by electromyography in combination with electrical stimulation in the treatment of upper limb spasticity poststroke.Methods Forty-five patients with upper limb spasticity following stroke were recruited.They received multiple intra-muscular BTX-A injections guided by electromyography and electrical stimulation.Rehabilitation training was administered after the BTX-A injections.The results were assessed using the modified Ashworth scale (MAS),the Fugl-Meyer upper limb assessment (FMA),active range of movement (AROM) and the modified Barthel index (MBI).All the assessments were performed at the baseline,and then 1 week,2 weeks,1 month,and 3 months after the injections.Results Compared with the baseline scores the MAS,FMA,AROM and MBI results had all obviously improved by 2 weeks after the BTX-A injections.Compared with 2 weeks after the injections,the FMA and AROM scores at 1 month were significantly higher and there were further significant improvements at 3 months.No patient demonstrated obvious side effects from the therapy.Conclusion BTX-A injection guided by electromyography and electrical stimulation is safe and has definite beneficial effects on upper limb spasticity after stroke.
RESUMO
ObjectiveTo detect the fiber structure and volume differences in frontal lobe between patients with amnestic mild cognitive impairment (aMCI) and normal control.MethodsT1 -weighted magnetic resonance imaging and diffusion tensor imaging were obtained in 28 aMCI patients and 25 normal controls.Volumes,fiber fractional anisotropy (FA),fiber apparent diffusion coefficient (ADC),fiber number,and average fiber length of frontal lobe in the two groups were measured.ResultsVolumes of left frontal lobe ( ( 337.35 ± 20.45 ) cm3 ) in aMCI group were smaller than control ( (358.54 ± 27.26) cm3 ) ( t =- 3.223,P =0.002 ).Numbers of short range fiber in left frontal lobe ( 16985 ± 892) were significantly increased relative to control ( 16387 ±752) ; while numbers of long range fiber (3214 ± 185 ) were reduced compared with control (3425 ± 277 ),and ADC values increased ( t =2.621,P =0.012; t =-3.714,P =0.001 ; t =17.595,P=0.000).In aM CI group,numbers of long range fiber in right frontal lobe were reduced (2895 ± 343 vs.3451 -± 230,t =- 7.011,P =0.000),and ADC values were increased ( t =4.443,P =0.000).In aMCI group,numbers of long range fiber in left frontal lobe were positively correlated with scores of mini-mental state examination ( MMSE ) ( r =0.457,P =0.015 ),while ADC values of long range fiber in left frontal lobe were negatively correlated with scores of MMSE ( r=-0.415,P=0.028).ConclusionThe structure and fiber connectivity are affected in aMCI patients and the lesion of connectivity in left frontal lobe are related to the severity of symptom.
RESUMO
[Objective]To establish a novel noninvasive fluorescent animal model for endometriosis in vitro and in vivo.[Methods]Adenovirus encoding enhancing green fluorescent protein(Ad-eGFP)was used to transfect endometrial glandular cells and stromal cells(cells transfection and injection,Method No.1),and fragments(tissues transfection and injection,Method No.2).Transfection efficiencies were compared between the two methods in vitro.Then GFP transfected glandular cells and stromal cells suspension were injected into nude mice subcutaneously(Method No.1),taking Method No.2 as a comparison.In vivo observation last for 25 days,and positive rates and duration times of fluorescent lesions were calculated.Histological examination was used to confirmed lesion formation.[Results]On the fifth day after injection,lesion positive rate of Method No.1 was 88.9%,which was statistically significantly higher than that of Method No.2(22.2%),P=0.015＜0.05.The fluorescent positive duration of Method No.1 and No.2 were 12 ± 8 days and 7±4 days.The structures of lesions were all identified as human original endometrium by histological examination,including HE staining and immunofluoresceney.[Conclusion]Noninvasive animal model of endometriosis can be built up by subcutaneously injection of Ad-EGFP transfected endometrial glandular cells and stromal cells suspension with higher positive rate and longer observation time
