Tuina (massage) therapy for diarrhea in COVID-19

Ke-Lin Zhou, Shuo Dong, Guo-Bing Fu, Shu-Sheng Cui, Sheng Guo
2020 Medicine  
In the beginning of December 2019, the novel coronavirus pneumonia was first detected in Wuhan, China. Its widespread infectivity and strong pathogenicity has posed a great threat to public health, seriously affecting social production and life. Accumulating evidence suggests that gastrointestinal symptoms, such as diarrhea, are common among patients with COVID-19. Tuina (massage) therapy is 1 of the widely employed complementary and alternative medicine interventions in the world. It can act

This systematic review and meta-analysis will summarize the current evidence of tuina (massage) used as an intervention for diarrhea symptoms in COVID-19. We will search the following electronic databases for randomized controlled trials to evaluate the effectiveness and safety of massage therapy in treating exercise-induced fatigue: China National Knowledge Infrastructure, Wanfang and Pubmed Database, Cochrane Central Register of Controlled Trials, Cumulative Index of Nursing and Allied Health Literature, Excerpta Medica database and MEDLINE. Each database will be searched from inception to June 2020. The entire process will include study selection, data extraction, risk of bias assessment and meta-analyses. This proposed study will evaluate the effectiveness and safety of massage therapy for diarrhea symptoms in COVID-19 patients. The outcomes will include the improvement of diarrhea symptoms and adverse effect. This proposed systematic review will evaluate the existing evidence on the effectiveness and safety of massage therapy for diarrhea symptoms in COVID-19 patients.Dissemination and ethics: The results of this review will be disseminated through peer-reviewed publication. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process.

The weighted mean difference was j0.26 mm (95% confidence interval, j0.31 to j0.21; p G 0.001) for axial length elongation based on data from seven studies and j0.18 mm (95% confidence interval, j0.33 to j0.03; p = 0.02) for vitreous chamber depth elongation based on data from two studies. Conclusions. Our results suggest that orthokeratology may slow myopia progression in children. Further large-scale studies are needed to substantiate the current result and to investigate the long-term effects of orthokeratology in myopia control. (Optom Vis Sci 2015;92:252Y257)

The extremely fascinating behaviors of the quantum walks of particles, which differ much from the classical counterparts, have attracted many physicists. Here we investigate another interesting part of the quantum walks, that is the quantum walks of waves. Firstly, we show the behaviors of the quantum walks of plane wave, which are largely different from the counterparts of either the classical or the quantum walks of particles. Two situations - with and without intermediate time measurements

SUMOylation of spastin promotes the internalization of GluA1 and regulates dendritic spine morphology by targeting microtubule dynamics

2020 Neurobiology of Disease  
Dendritic spines are specialized structures involved in neuronal processes on which excitatory synaptic contact occurs. The microtubule cytoskeleton is vital for maintaining spine morphology and mature synapses. Spastin is related to microtubule-severing proteases and is involved in synaptic bouton formation. However, it is not yet known if spastin can be modified by Small Ubiquitin-like Modifier (SUMO) or how this modification regulates dendritic spines. Spastin was shown to be SUMOylated at

SUMOylated spastin promoted the development of dendrites and dendritic spines. Moreover, SUMOylated spastin regulated endocytosis and affected the transport of the AMPA receptor, GluA1. Our findings suggest that SUMOylation of spastin promotes GluA1 internalization and regulates dendritic spine morphology through targeting of microtubule dynamics.

Sheng-Li Zhang, -Kun Wang, Jian-Sheng Guo, Jian-Hong Shi
2015 Chinese Physics Letters  
Quantum illumination, that is, quantum target detection, is to detect the potential target with two-mode quantum entangled state. For a given transmitted energy, the quantum illumination can achieve a target-detection probability of error much lower than the illumination scheme without entanglement. We investigate the usefulness of noiseless linear amplification (NLA) for quantum illumination. Our result shows that NLA can help to substantially reduce the number of quantum entangled states

We analyze the outcome of circumcisions performed with 8-figure non-absorbable suture (8FNS) and assess the feasibility of using the technique in male circumcision.Methods: We randomly divided 317 patients who would undergo circumcision between February 2009 and January 2012 into 2 groups. Each group was subdivided into children (age range: 7 to 15 years) and adult (range: 16 to 85 years). In the experiment group (n =166), we used 8FNS and in the control group (n = 151), commonly absorbable

Chi-square and Student's t-test were used in statistical analysis. Differences were considered significant (p < 0.05).Results: No patients were required to remove their sutures postoperatively.Among them, the sutures of the 8FNS for circumcision felloff spontaneously within 9 days (6.2 ± 1.57). There was no statisticallysignificant difference between the 2 groups in surgical duration (16.2 ± 1.73 vs. 15.8 ± 2.01) and follow-up time (6.4 ± 3.82 vs. 6.2 ± 2.39). The overall complication rate of the 2 groups was 6.63% and 10.53% (p = 0.15), respectively. In addition, the complication rate among the adults was significantly lower in the 8FNS group compared to children (2.53% vs. 10.34%, p = 0.04). Also, the average cost (in US dollars) of 8FNS for circumcision was $20.7 ± $3.83 less than $35.8 ± $5.02 of CAS, which is a very significant difference (p < 0.0001).Conclusions: 8FNS for circumcision is feasible, easy, safe and cost-effective, especially for adult males.

An in-depth study of the temporal and spatial distribution of pollution loads can assist in the development of water pollution remediation. The research scope of this paper was the highly developed Wuhu City located south of the Yangtze River. Chemical oxygen demand (COD), NH3-H, and total phosphorus (TP) were chosen as the pollutant research objects of this study. Then, by combining the natural and social conditions within the scope of the study, a balanced system of pollution load generation

The results indicate that, in terms of the time distribution, the changes in the influx of the different pollutants were consistent. In terms of the spatial distribution, the major contributions to the annual pollution load were domestic pollution, urban surface runoff pollution, and poultry breeding pollution. The major contributors to the annual pollution load into the river were domestic pollution, urban surface runoff pollution, and sewage plant tail water pollution. This analysis provides references for the comprehensive management of local water environments.

2019 Genes  
Animal growth and development are regulated by long non-coding RNAs (lncRNAs). However, the functions of lncRNAs in regulating cashmere fineness are poorly understood. To identify the key lncRNAs that are related to cashmere fineness in skin, we have collected skin samples of Liaoning cashmere goats (LCG) and Inner Mongolia cashmere goats (MCG) in the anagen phase, and have performed RNA sequencing (RNA-seq) approach on these samples. The high-throughput sequencing and bioinformatics analyses

Gene ontology (GO) analyses of lncRNAs and target genes in cis show a predominant enrichment of targets that are related to intermediate filament and intermediate filament cytoskeleton. According to the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, sphingolipid metabolism is a significant pathway for lncRNA targets. In addition, this is the first report to reveal the possible lncRNA–mRNA regulatory network for cashmere fineness in cashmere goats. We also found that lncRNA XLOC_008679 and its target gene, KRT35, may be related to cashmere fineness in the anagen phase. The characterization and expression analyses of lncRNAs will facilitate future studies on the potential value of fiber development in LCG.
