Objective:To explore the effect of tibial nerve vibration on triceps surae spasticity in stroke survivors and its electrophysiological mechanism.Methods:Thirty stroke survivors with upper limb spasticity were randomly divided into a treatment group and a control group, each of 30. Both groups were given routine rehabilitation training while the treatment group was additionally provided with local vibration of the tibial nerve with an amplitude of 0.3mm at 60Hz. Before and after the treatment, the modified Ashworth scale (MAS) and Clonus grading were used to assess muscle tone and spasticity. Electrophysiological functions were evaluated using the tibial nerve motor and sensory conduction test and F wave and H reflex sensing.Results:Before the treatment there were no significant differences between the two groups in their average MAS scores, Clonus grading, maximum H amplitude (Hmax), the ratio of maximum H to maximum M amplitude (H/M) or the intensity of stimulus required to elicit Hmax. After the treatment, however, all of those measurements had improved significantly in both groups with the average improvements in the treatment group significantly greater than those in the control group.Conclusions:Local vibration of the tibial nerve combined with traditional rehabilitation is more effective than traditional rehabilitation alone in relieving triceps surae spasticity and reducing muscle tone after a stroke. The vibration seems to inhibit excitation of the reflex pathway.

Phage therapy is one of the most important tools for the treatment of infections with multi-drug resistant bacteria. Such phages are usually isolated from hospital effluents, however, no systematic study on the distribution of phages in hospital effluents has been conducted so far. The aim of this study was to isolate the corresponding phages of common pathogenic bacteria isolated in the clinic as hosts, so as to assess the ecological distribution of phages in hospital wastewater and to provide a reference for the isolation and application of phages of drug-resistant bacteria in the clinic. A cross-sectional study design was used in this study. The 125 pathogenic bacteria (belonging to 16 different strains) isolated from the clinical microbiology laboratory of Qilu Hospital of Shandong University from May to June 2023 were selected as the target strains, and the phages corresponding to these strains were isolated and purified from the hospital wastewater by using the double-layer plate sandwich method. At the same time, the distribution of pathogenic bacteria in the same batch of wastewater was analyzed with the help of mNGS sequencing technology, so as to preliminarily investigate the abundance correspondence between pathogenic bacteria and phages in wastewater. The results showed that a total of 56 phage strains were isolated from 125 clinical pathogens as hosts, corresponding to six pathogens, including Acinetobacter baumannii, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia. All six pathogenic bacteria contained strains with different degrees of drug resistance, with a higher percentage of multi-drug resistant strains in A. baumannii, Escherichia coli and P. aeruginosa. The phage acquisition rates of these six pathogens were, in descending order, Escherichia coli (80%), Stenotrophomonas maltophilia (75%), Pseudomonas aeruginosa (70%), Klebsiella pneumoniae (66.67%), Acinetobacter baumannii (36.36%) and Staphylococcus aureus (12.5%). Preliminary mNGS sequencing results showed that the pathogenic bacteria with higher abundance in the batch of effluent were Enterococcus faecalis, Klebsiella pneumoniae, Escherichia coli, Enterococcus faecalis, Acinetobacter baumannii, Klebsiella aerogenes, Klebsiella michiganensis and Pseudomonas aeruginosa. In conclusion, phages of most common clinical Gram-negative pathogens were isolated from hospital wastewater with high isolation rates; however, phages of Gram-positive pathogens were isolated at lower rates, and only phages corresponding to Staphylococcus aureus were isolated in this study. The corresponding mNGS sequencing results showed that the distribution of Gram-negative pathogens in sewage may had a positive correlation with the ecological distribution of phages.
