RESUMEN
BACKGROUND: As one of the most common musculoskeletal ailments, chronic nonspecific low-back pain (CNLBP) causes persistent disability and substantial medical expenses. Epidemiological evidence shows that the incidence rate of CNLBP in young and middle-aged people who are demanded rapidly recovery and social contribution is rising. Recent guidelines indicate a reduced role for medicines in the management of CNLBP. OBJECTIVE: The present study investigates the short-term effects of cupping and scraping therapy using a medicated balm, compared to nonsteroidal anti-inflammatory drug (NSAID) with a capsaicin plaster, in the treatment of CNLBP. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: We designed a prospective multicenter randomized clinical trial enrolling patients from January 1, 2022 to December 31, 2022. A total of 156 patients with CNLBP were randomized into two parallel groups. Diclofenac sodium-sustained release tablets were administered orally to participants in the control group for one week while a capsaicin plaster was applied externally. Patients in the test group were treated with cupping and scraping using a medical device and medicated balm. MAIN OUTCOME MEASURES: Primary outcome was pain recorded using the visual analogue scale (VAS). Two secondary outcomes were recorded using the Japanese Orthopedic Association low-back pain scale (JOA) and the traditional Chinese medicine (TCM) syndrome integral scale (TCMS) as assessment tools. RESULTS: Between baseline and postintervention, all changes in outcome metric scales were statistically significant (P < 0.001). Compared to the control group, patients in the test group had a significantly greater treatment effect in all outcome variables, as indicated by lower VAS and TCMS scores and higher JOA scores, after the one-week intervention period (P < 0.001). Further, according to the findings of multivariate linear regression analysis, the participants' pain (VAS score) was related to their marital status, age, smoking habits and body mass index. No adverse reactions were reported for any participants in this trial. CONCLUSION: The effectiveness of TCM combined with the new physiotherapy tool is superior to that of NSAID combined with topical plasters, regarding to pain intensity, TCM symptoms and quality of life. The TCM plus physiotherapy also showed more stable and long-lasting therapeutic effects. TRIAL REGISTRATION: This study was registered at Chinese Clinical Trial Registry (ChiCTR2200055655).

Fructose overconsumption promotes tumor progression. Neuroblastoma is a common extracranial tumor with about 50% 5-year survival rate in high-risk children. The anti-tumor effect of Tribulus terrestris might bring new hope to neuroblastoma therapy. However, whether fructose disturbs the therapeutic effect of T. terrestris is currently unknown. In this study, the mouse neuroblastoma cell line, Neuro 2a (N2a) cells, was used to investigate the therapeutic effects of T. terrestris extract at various dosages (0.01, 1, 100 ng/ml) in regular EMEM medium or extra added fructose (20 mM) for 24 h. 100 ng/ml T. terrestris treatment significantly reduced the cell viability, whereas the cell viabilities were enhanced at the dosages of 0.01 or 1 ng/ml T. terrestris in the fructose milieu instead. The inhibition effect of T. terrestris on N2a migration was blunted in the fructose milieu. Moreover, T. terrestris effectively suppressed mitochondrial functions, including oxygen consumption rates, the activities of electron transport enzymes, the expressions of mitochondrial respiratory enzymes, and mitochondrial membrane potential. These suppressions were reversed in the fructose group. In addition, the T. terrestris-suppressed mitofusin and the T. terrestris-enhance mitochondrial fission 1 protein were maintained at basal levels in the fructose milieu. Together, these results demonstrated that T. terrestris extract effectively suppressed the survival and migration of neuroblastoma via inhibiting mitochondrial oxidative phosphorylation and disturbing mitochondrial dynamics. Whereas, the fructose milieu blunted the therapeutic effect of T. terrestris, particularly, when the dosage is reduced.

Vegetable waste is one of the major organic solid residues available for sustainable biogas production. The aim of this study was to investigate the possibility and optimal controlling strategy for acidogenic fermentation of wasted potato (WP). Three leaching bed reactors (LBRs) were operated at various pH values (6.0, 7.0 and 8.0) with an organic loading rate (OLR) of 6.7 g volatile solid/(L·d) and hydraulic retention time of 6 d. Butyric acid-type fermentation with butyric acid as predominant volatile fatty acid (VFA) was observed with a concentration and proportion (of total VFAs) of butyric acid, which were 7.8 g/L, 49.7 % and 9.6 g/L and 52.2 % at pH 6.0 and 7.0, respectively. Conversely, at pH 8.0, mixed acid-type fermentation was observed with acetic and butyric acid as the major VFAs. Control experiment without pH manipulation didn't perform well in VFAs production at first 6 days and then VFAs concentration increased as pH value was adjusted to 8. It was indicated that the inhibition was caused by high undissociated VFAs concentration due to low pH and the VFAs production could be improved through pH control strategy to regulate the undissociated VFAs concentration. According to the bacterial analysis, the microbial community was diverse and Firmicutes were the most important bacteria at different pH conditions. Therefore, the results suggested that a process of pH control might be feasible for stable and efficient acidogenic fermentation.

Anaerobic granular sludge was used as an inoculum for co-digestion of potato waste (PW) and cabbage waste (CW) in batch and semi-continuous modes at 37±1°C for enhanced methane generation. Batch test results indicated that an equal proportion (1:1) by volatile solid was the optimal mixing ratio for co-digestion of PW and CW. Semi-continuous co-digestion process results showed that the stepwise increasing of the organic loading rates from 1.0 to 5.0kgVS/m3·d improved the methane yield from 224 to 360mL/g-VS. And the highest value was respectively 18.4% and 24.1% higher as compared to the mon-digestion of PW and CW. Further investigation with high-throughput sequencing analysis revealed that the enhanced methane generation was attributed to the partial shift from archaeal Methanosaeta to Methanosarcina and Methanobacterium, and from bacterial Firmicutes to Bacteroidetes and Proteobacteria. The volatile fatty acids concentration accounted for the modification of microbial communities.

The Alzheimer's disease (AD) has a wide spectrum of symptoms, ranging from cognition dysfunction to behavior disturbances and functional impairment. The evoked cerebral potentials by specific paradigms are useful for disclosing neuropsychological activities. The evolution of AD is accompanied by progressive cognitive impairment which may result in a difficulty to recognize or comprehend gestures. In the present study, a visual tool-using gesture paradigm was employed to assess the cognitive functions of 16 probable AD patients, 17 subjects mild cognitive impairment (MCI), and 17 age-matched control subjects. Each subject was conducted by visual stimuli by a series of pictures, each displaying randomly a gesture with correctly or incorrectly using a tool. The P300 amplitude was further used as a parameter to build classifiers based on support vector machine.

Sinomenine (SIN) is the active principle of the Chinese medical plant Sinomenium acutum which is widely used for the treatment of rheumatoid arthritis (RA) in China. Recently, several groups indicated that myeloid differentiation primary response protein 88 (MyD88) might be associated with disease progression of RA. Here, we observed the effect of SIN on MyD88 expression and showed its therapeutic role in RA. First, immunohistochemical staining in clinical specimens showed that MyD88 was mainly located in characteristic pathological structures of RA synovial tissues. Second, we found that MyD88 was overexpressed in the synovial tissues of the rats with adjuvant-induced arthritis (AIA). Treatment with SIN markedly decreased the expression of MyD88 in AIA rats. Finally, we provided evidences that SIN suppressed inflammation response and inflammation-induced joint destructive progression and arthritis symptoms in AIA rats. Therefore, SIN is an effective therapeutic agent for RA. Targeting MyD88 signaling may provide new methods for the treatment of RA.

The effects of AgNPs and Ag+ (0-5 mg/L) on wastewater enhanced biological phosphorus removal (EBPR) were investigated. The phosphorus removal efficiency was maintained at 99% no matter what the concentrations of AgNPs were, but it was decreased to 48.8% at Ag+ of 1 mg/L, and no net phosphorus was removed at Ag+ greater than 2 mg/L in the batch tests. The uptake of wastewater carbon source and the anaerobic and aerobic transformations of phosphorus, polyhydoxyalkanoates and glycogen were inhibited by Ag+ other than AgNPs. Ag+ showed stronger toxicity on polyphosphate accumulating organisms (PAOs) than glycogen accumulating organisms (GAOs). Further investigation revealed that the decrease in anaerobic phosphorus release by Ag+ was caused by the inhibition on the activities of adenylate kinase and expolyphosphatase, whereas the decrease in aerobic phosphorus uptake was due to the suppression in energy generation for phosphorus uptake. However, the presence of either AgNPs or Ag+ did not lead to cell leakage and membrane damage.

A practical, inexpensive, and green chemical process is greatly needed for degrading pesticides in food and environmental water. In this work, the impact of O(2) plasma treatment on reduction of dichlorvos (DDVP) and omethoate in maize was determined by gas chromatography (GC). The main plasma-induced degradation mechanisms were investigated through identification of intermediates or products during O(2) plasma treatment for DDVP and omethoate on solid surfaces by gas chromatography/mass spectrometry (GC/MS). The results clearly demonstrate that O(2) plasma treatment is significantly effective in the degradation of original DDVP and omethoate, and the degradation efficiency mainly depends upon related operating parameters and chemical structures of pesticides. Moreover, GC/MS analyses show that DDVP and omethoate molecules are degraded into less-toxic compounds, and the plasma degradation mechanisms for pesticides can be dominated by a free-radical reaction. It is concluded that O(2) plasma has the potential to reduce pesticide residues in agricultural products.
