Yi and Gui,its physiological characteristics and pathological manifestations are closely related to the lumbar spine.The intervertebral disc,chamber of arthrosis,requires nourishment from qi and blood circulation,as well as support from liver and kidney functions to maintain its health.Chinese medicine master Shi Qi has based on the pathological manifestations of discogenic low back pain patients at different stages and followed the guidelines of the Visceral manifestation theory.Combining more than 60 years of experience in traditional Chinese medicine diagnosis and treatment,he has used external observations to infer internal conditions and examined causes to find solutions.By entering the body from the outside and focusing on the"Homology of Yi and Gui"as a benchmark,he emphasizes the distinctive characteristic of traditional Chinese medicine in medical treatment.He states that"visceral pattern is fundamental"and"qi-blood is first,"emphasizing the importance of treating liver and kidney together.This article aims to draw on the wisdom of Taishan to provide a bridge for colleagues.

Objective To establish a rat model of venous thrombosis in a plateau hypobaric hypoxic environment and to investigate the effect of this environment on venous thrombosis.Methods A total of 144 healthy male SD rats were assigned randomly to four groups(n=36 rats per group):a plains sham operation(A)group,plains operation(B)group,plateau altitude 6000 m+sham operation(C)group,and plateau altitude 6000 m+surgery(D)group.Rats in A and B groups were maintained in a plains normoxic environment,while rats in C and D groups C and D were subjected to a plateau environment.Rats in the surgical groups underwent quantitative constriction to incompletely obstruct the inferior vena cava blood flow.Each group was further divided into subgroups based on time:1,3,5,7,14,and 21 d(n=6 rats per group).Regular vascular ultrasound monitoring was conducted,and blood samples were taken for whole blood viscosity testing and the assessment of inflammatory indicators,including endothelin-1(ET-1),interleukin-6(IL-6)and tissue factor(TF).Coagulation function was evaluated through the activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB)and D-dimer.After the observation period,the experimental animals were sacrificed and the limbs were removed.Thrombus samples were stained with hematoxylin/eosin(HE),and the thrombus wet mass was measured.Results The thrombosis incidence was significantly higher in the plateau D group than in B group,accompanied by a marked increase in blood viscosity and hematocrit(P＜0.01).Additionally,levels of ET-1,IL-6,and TF were significantly elevated(P＜0.05),indicating a coagulation disorder.Conclusions A plateau hypoxic environment model can be successfully simulated by quantitative coarctation of the inferior vena cava,combined with a specialized environmental chamber.The findings of this study suggest that a plateau hypoxic environment promotes venous thrombosis.

Objective To realize real-time monitoring and evaluation of muscle strength,this study designed and validated a wearable muscle strength monitoring system based on muscle perimeter changes.Methods Six healthy college students who are not sports majors wore the monitoring gear based on the change of muscle perimeter to perform the isokinetic muscle strength test,the real-time data of the change of muscle perimeter during the isokinetic exercise was obtained.After analyzing and processing the curve of muscle perimeter change overtime,namely,the peak muscle perimeter change(PP),the peak velocity of muscle perimeter change(PVP)and the accumulation of muscle perimeter change(AP)over time in a single exercise,Pearson correlation analysis was conducted with the peak torque(PT),the peak torque to body weight ratio(PT/BW),the torque at 0.18 s(T0.18)and the endurance ratio(ER)obtained by the isokinetic muscle strength test.The reliability of wearable system for real-time muscle strength monitoring was verified.The muscle perimeter changes were sampled with the arm and leg wearable protectors,and the muscle perimeter monitoring positions corresponded to the largest muscle perimeter changes when the strength of biceps in the upper arm was applied,as well as the largest muscle perimeter changes when the strength of quadriceps above the knee was applied.The isokinetic muscle strength test was performed on elbow and knee joints using the Biodex System 4 pro device.Results Dynamic muscle perimeter changes could be used to monitor the muscle strength level of the human body.There was a significant correlation between arm muscle perimeter and elbow muscle strength index(P≤0.01),and the maximum correlation coefficient was 0.91.Leg muscle perimeter was significantly correlated with knee muscle strength(P≤0.01),and the maximum correlation coefficient was 0.99.Conclusions The wearable muscle strength monitoring system has a high reliability and can be used for real-time monitoring of the elbow and knee muscle strength during isokinetic exercise.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.
