[Effect of Scalp Electroacupuncture Combined Constraint-induced Movement Therapy on Move- ment Function of Ischemic Stroke Patients' Upper Limbs].

Objective To observe the effects of scalp electroacupuncture (SEA) combined con- straint-induced movement therapy ( CIMT) on movement function of ischemic stroke patients' upper limbs. Methods Totally 80 stroke patients were assigned to four groups according to random digit table, i.e., the routine rehabilitation group, the SEA group, the CIMT group, and the comprehensive intervention group. Patients in the routine rehabilitation group strengthened the training of upper limbs on the affected side by Bobath dominated technology and Brunnstrom assisted technology. Patients in the SEA group received Jiao's SEA combined EA therapy. Those in the CIMT group restricted the upper limbs of the healthy side and strengthened training of the affected side. Those in the comprehensive intervention group used SEA combined CIMT treatment. Fugl-Meyer assessment scale (FMA) , grading of hand function and range of wrist movement were observed before intervention, at week 4 and 12 after intervention, respectively. Results Compared with before treatment in the same group, FMA scores of upper limbs significantly increased, grading of hand function, and range of wrist movement were obviously improved in the 4 groups after 4-week treatment (P <0. 05, P <0. 01). There was no statistical difference in FMA scores of upper limbs or grading of hand function among the four groups. But dorsal expansion of wrist and radial deviation were more obviously improved in the comprehensive intervention group than in the routine rehabilitation group (P <0. 05). Compared with the routine rehabilitation group, FMA scores of up- per limbs increased, grading of hand function and range of wrist movement were obviously improved in the comprehensive intervention group (P <0. 05). Conclusions Routine rehabilitation, SEA, and CIMT showed better rehabilitation effect on movement function of ischemic stroke patients' upper limbs. But ESA combined CIMT showed most obvious effect with earliest effect shown.

The agreement of different techniques for muscle measurement in diagnosing sarcopenia: a systematic review and meta-analysis.

Background: The measurement or estimation of muscle mass plays an important role in the diagnosis of sarcopenia. Beside dual-energy X-ray absorptiometry (DXA), several modalities, including bioelectrical impedance analysis (BIA), ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), have helped to provide imaging or electrical biomarkers for muscle mass. This study was aimed at summarizing the diagnostic performance of different techniques on muscle assessment for sarcopenia. Methods: Studies on the assessment of muscle mass by different techniques (compared with DXA), published from inception to 12 October, 2023 were retrieved from 4 electronic databases: the Cochrane Library, Embase, PubMed, and Web of Science. The quality assessment of included studies was conducted using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). The sensitivity, specificity, Cohen's kappa coefficient (κ), and Pearson correlation coefficient (r) with 95% confidence intervals (CIs) were pooled and presented via forest plots. The area under the curve (AUC) with 95% CI was pooled and presented via summary receiver operating characteristic (sROC) curve. Results: A total of 28 studies involving 4,926 participants were included. Compared with DXA, the pooled sensitivity and specificity, AUC, and Cohen's κ were 0.79 (95% CI: 0.71-0.86, P<0.001), 0.95 (95% CI: 0.82-0.99, P<0.001), and 0.88 (95% CI: 0.85-0.90), and 0.61 (95% CI: 0.51-0.72) for BIA. The pooled r value between DXA and BIA or US or MRI was 0.94 (95% CI: 0.92-0.96, P<0.001), 0.69 (95% CI: 0.54-0.80, P<0.001), and 0.96 (95% CI: 0.95-0.97, P=0.21), respectively. No qualified original study in relation to CT was included. Conclusions: BIA, US, and MRI would provide acceptable diagnostic accuracy for sarcopenia by evaluating muscle mass in terms of sensitivity, specificity, accuracy, and their higher correlations with DXA. Further investigation is required to elucidate the value of CT in diagnosing sarcopenia.

Effects of substrates and suppliers of ingredients on microbial community and metabolites of traditional non-salt Suancai.

Aim: Non-salt Suancai is an acidic fermented vegetable consumed by the Chinese Yi ethnic group. Traditionally, it is produced by fermentation without salt in a cold environment. The present study aimed to investigate the metabolite and microbial characteristics, and the effects of substrates/suppliers ingredients on non-salt Suancai. Methods: A simulated fermentation system of non-salt Suancai was constructed by using different substrates/suppliers' ingredients. The coherence and differential detection of the metabolite and microbial characteristics were done through non-target metabolomic and metagenomic analysis. Results: Lactic acid was the predominant organic acid across all samples. The enumeration of the Lactic acid bacteria showed no discernible differences between study groups, but that of yeast was highest in the mustard leaf stem (Brassica juncea var. latipa). The three major biological metabolic pathways were metabolism, environmental information, and genetic information processing based on the KEGG database. The metabolite diversity varied with the substrate/supplier of ingredients based on the PLS-DA plot. Lactiplantibacillus, Leuconostoc, and Lactococcus were prevalent in all samples but differentially. The microbial diversity and richness varied significantly, with 36~291 species being identified. Among the various substrates collected from the same supplier, 29, 59, and 29 differential species were identified based on LEfSe [linear discriminant analysis (LDA) > 2, P < 0.05]. Leuconostoc citreum, Leuconostoc mesenteroides, Leuconostoc pseudomesenteroides, Lactiplantibacillus plantarum, and Leuconostoc lactis were likely to be used as the species to discriminate samples collected from different suppliers. Conclusions: This research contributed to the exploration of microbial and metabolite characteristics behind the ingredient restriction of non-salt Suancai using traditional technology.

Global burden and trends in pre- and post-menopausal gynecological cancer from 1990 to 2019, with Projections to 2040: a cross-sectional study.

BACKGROUND: The global burden and trends in gynecological cancer (GC) by menopausal status worldwide remain unclear. METHODS: Data on the number of incident cases and deaths, as well as age-standardized rates (ASR) and risk factors for GC in pre- and post-menopausal women were obtained from the Global Burden of Disease (GBD) Study 2019. The estimated annual percent change was calculated to quantify the temporal trend of GC burden by menopausal status between 1990 and 2019. The Bayesian age-period-cohort model was used to predict the trends in age-standardized incidence and mortality rates for pre- and post-menopausal GC during 2020-2040. RESULTS: In 2019, an estimated 400,146 premenopausal and 879,476 postmenopausal GC cases were newly diagnosed worldwide, with approximately 111,420 and 442,821 GC-related deaths occurring in each menopausal group, respectively. The majority of both pre- and post-menopausal GC cases in low- to middle-SDI regions was due to cervical cancer. In high- and high-middle-SDI regions, premenopausal GC was primarily attributed to cervical cancer, while postmenopausal GC was mainly attributed to uterine cancer. Additionally, the contribution of uterine cancer to GC was higher among postmenopausal women than premenopausal women, across all SDI levels and geographical regions. ASIRs either remained stable or increased from 1990 to 2019 worldwide for both pre- and post-menopausal GC (an average change of 0.03% [95% CI -0.02 to 0.08] and 0.09% [0.05 to 0.13] per year, respectively). However, the age-standardized mortality rates (ASMRs) declined by an annual average of 0.86% (95% CI -0.92 to -0.8) and 0.63% (95% CI -0.66 to -0.6) globally during the same period. The risk-attributable proportion of postmenopausal GC deaths was higher than that of premenopausal GC and increased with increasing SDI. The projections indicate an increasing trend in the burden of premenopausal GC from 2020 to 2040, while the burden of postmenopausal GC is expected to decline. CONCLUSIONS: GC continues to be a significant public health concern worldwide, with notable regional and demographic disparities in the burden based on menopausal status. Policymakers and health-care providers must be proactively aware of these evolving trends and tailor age-appropriate and region-specific screening strategies, as well as allocate resources accordingly.

Transcriptomic Analysis of Human Skeletal Muscle in Response to Aerobic Exercise and Protein Intake.

This study aimed to provide a more comprehensive molecular insight into the effects of aerobic exercise (AE), protein intake (PI), and AE combined with PI on human skeletal muscle by comparing their transcriptomic profiles. Fourteen published datasets obtained from the Gene Expression Omnibus (GEO) database were used. The hub genes were identified in response to acute AE (ACTB, IL6), training AE (UBB, COL1A1), PI (EZH2), acute AE combined with PI (DDIT3), and training AE combined with PI (MYC). Both FOS and MYC were upregulated in response to acute AE, and they were, respectively, downregulated by higher PI and a combination of AE and PI. COL1A1 was upregulated by training AE but was downregulated by higher PI. Results from the gene set enrichment analysis (p < 0.05 and FDR < 25%) showed that AE and PI delivered their impacts on human skeletal muscle in analogous pathways, including aerobic respiration, mitochondrial complexes, extracellular matrix (ECM) remodeling, metabolic process, and immune/inflammatory responses, whereas, PI may attenuate the response of immune/inflammation and ECM remodeling which would be promoted by AE, irrespective of its types. Compared to PI alone, acute AE combined with PI would further promote protein turnover and synthesis, but suppress skeletal muscle contraction and movement.

Characterizing the impact of species/strain-specific Lactiplantibacillus plantarum with community assembly and metabolic regulation in pickled Suancai.

To investigate the colonization and impact of the specific Lactiplantibacillus plantarum strains, four isolated strains were applied in pickled Suancai which is a traditional pickled mustard (Brassica juncea). Results showed that strain-8 with the highest lactic acid bacteria (LAB) counts and acetic acid (p < 0.05). There were 11.42 % ∼ 32.35 % differential volatile compounds detected, although nitriles, esters, and acids were predominant. L. plantarum disturbed the microbial community, in which the microbial composition of strain-11 was most similar to the naturally fermented sample. Amino acids, carbohydrate metabolism, and metabolism of cofactors and vitamins were the main functional classes because of the similar dominant microbes (Lactiplantibacillus and Levilactobacillus). The functional units were separated based on NMDS analysis, in which bacterial chemotaxis, amino acid-related units, biotin metabolism, fatty acid biosynthesis, and citrate cycle were significantly different calculated by metagenomeSeq and Benjamin-Hochberg methods (p < 0.05). The contents of most flavor compounds were consistent with their corresponding enzymes. In particular, glucosinolates metabolites were different and significantly related to the myrosinase and metabolic preference of LAB. Therefore, this study revealed the impact mechanism of the specific L. plantarum strains and provided a perspective for developing microbial resources to improve the flavor diversity of fermented vegetables.

Unraveling the contribution of pre-salting duration to microbial succession and changes of volatile and non-volatile organic compounds in Suancai (a Chinese traditional fermented vegetable) during fermentation.

Pre-salting is an important pre-treatment during production of Suancai as it provides flavor precursor and microbial community for subsequent fermentation. To investigate the effect of pre-salting duration on fermentation of Suancai, the physicochemical properties, microbial composition, non-volatile and volatile organic compounds profiles of Suancai pre-salted for 1 month (1 M) and 7 months (7 M) were analyzed during fermentation for 30 days. Results showed that 7 M led to higher salt content, faster depletion of reducing sugars, and more titratable acidity. Additionally, more lactic acid and acetic acid, and less umami amino acid (Glu) and GABA were observed in 7 M. Longer pre-salting duration (7 M) promoted formation of mild-flavor volatile compounds, and significantly reduced isothiocyanates with pungent off-flavor. Moreover, 7 M promoted abundance of genera Chromohalobacter, Vibrio and Pichia, while reducing abundance of Lactobacillus, Debaryomyces and Kazachstania throughout fermentation. These results implicated that longer pre-salting duration facilitated more acidic, milder flavor and less pungent off-odor in Suancai. This study provided a perspective for pre-salting as a control point for improving quality of fermented vegetable.

Association between Take-Out Food Consumption and Obesity among Chinese University Students: A Cross-Sectional Study.

BACKGROUND: The frequency of take-out food consumption has increased rapidly among Chinese college students, which has contributed to high obesity prevalence. However, the relationships between take-out food consumption, body mass index (BMI), and other individual factors influencing eating behavior among college students are still unclear. This study explored the association of take-out food consumption with gender, BMI, physical activity, preference for high-fat and high-sugar (HFHS) food, major category, and degree level among Chinese college students. METHODS: Cross-sectional data were collected from 1220 college students in Beijing, China, regarding information about take-out food consumption, physical activity, and preference for HFHS food using a self-reported questionnaire. The logistic linear regression model was used to analyze the association between take-out food consumption and personal and lifestyle characteristics. RESULTS: Out of 1220 college students, 11.6% of college students were overweight or obese. Among the personal and lifestyle characteristics, high frequency of take-out food consumption was significantly associated with a non-medical major, high preference for HFHS food, degree level, and higher BMI, but not physical activity. CONCLUSION: Among Chinese college students, consumption of take-out food may be affected by major category, preference for HFHS food, degree level, and BMI. This could provide guidance on restrictions of high take-out food consumption, which contributes to high obesity prevalence and high risk for metabolic diseases.

Expression of MuRF1 and MAFbx in donor and recipient muscles after musculocutaneous nerve transection and partial pectoralis major muscle transfer for reconstruction of elbow flexion in rats / Expresión de MuRF1 y MAFbx en músculos donantes y receptores después de transección del nervio musculocutáneo y transferencia parcial del músculo pectoral mayor para la reconstrucción de flexión de codo en ratas

The expression of MuRF1 and MAFbx in a denervated muscle has previously been studied. However, the expression of MuRF1 and MAFbx in the recipient and donor muscles after muscle transfer for reconstruction of joint function has not been sufficiently investigated. Forty-two adult Sprague-Dawley rats were divided into 7 groups: normal, 1 w post-, 2 w post-, and 4 w post-musculocutaneous nerve transection; and 1 w post-, 2 w post-, and 4 w post-reconstruction of elbow flexion. Muscle wet weights were assessed, and MuRF1 and MAFbx mRNA expressions were detected by polymerase chain reaction. The length of the oblique part of the pectoralis major of an SD rat is sufficient for suture to the insertion of the biceps brachii tendon. The muscle wet weight and the wet weight retention rate of the biceps brachii continued to decline after musculocutaneous nerve transection and a gradual increase was noted after the oblique part of the pectoralis major was transferred for reconstruction of elbow flexion. The oblique part of the pectoralis major showed a decrease of only 2­6%. The upregulated expression of MuRF1 and MAFbx in the biceps brachii reached a peak 2 w after denervation and 1 w after elbow flexion reconstruction, with an increase of 15% and 4%, respectively. This was followed by downregulation; however, the expression had not normalized at postoperative 4 w. The increased expression of MuRF1 (17%) and MAFbx (1%) in the oblique part of the pectoralis major at postoperative 1 w had decreased to below normal levels at postoperative 4 w. The transfer of the oblique part of the pectoralis major for elbow flexion reconstruction after musculocutaneous nerve transection can downregulate the expression of MuRF1 and MAFbx in the recipient muscle and causes only transient damage to the donor muscle in rats.

La expresión de MuRF1 y MAFbx en un músculo denervado ha sido estudiada previamente. Sin embargo, la expresión de MuRF1 y MAFbx en los músculos receptores y donantes después de la transferencia del músculo para la reconstrucción de la función articular no se ha investigado lo suficiente. Cuarenta y dos ratas adultas Sprague-Dawley fueron divididas en 7 grupos: normales, 1 semana post-, 2 semanas post- y 4 semanas post-transección del nervio musculocutáneo; y 1 semana post-, 2 semanas post-, y 4 semanas post-reconstrucción de la flexión del codo. Se evaluó el peso de los músculos húmedos, y las expresiones de MuRF1 y MAFbx mRNA fueron detectadas a través de reacción en cadena de la polimerasa. La longitud de la parte oblicua del músculo pectoral mayor de una rata Sprague-Dawley es suficiente para realizar la sutura en la inserción del tendón de músculo bíceps braquial. El peso húmedo del músculo bíceps braquial y su tasa de retención siguieron disminuyendo después de la sección del nervio musculocutáneo y un aumento gradual se observó después de la transferencia de la parte oblicua del músculo pectoral mayor para la reconstrucción de la flexión del codo. La parte oblicua del músculo pectoral mayor mostró una disminución de sólo 2-6%. La expresión regulada por incremento de MuRF1 y MAFbx en el bíceps braquial alcanzó un peak 2 semanas después de la denervación y 1 semana después de la reconstrucción de la flexión del codo, con un incremento del 15% y el 4%, respectivamente. Esto fue seguido por un regulación en baja. Sin embargo, la expresión no se normalizó en el postoperatorio de las 4 semanas. El aumento de la expresión de MuRF1 (17%) y MAFbx (1%) en la parte oblicua del músculo pectoral fue mayor en el postoperatorio de 1 semana, mientras que se encontró por debajo de los niveles normales en el postoperatorio de 4 semanas. La transferencia de la parte oblicua del músculo pectoral mayor para la reconstrucción de la flexión del codo después de la sección del nervio musculocutáneo puede regular a la baja la expresión de MuRF1 y MAFbx en el músculo receptor y provocar solo un daño transitorio en el músculo donado en ratas.
