Assessing the causal relationship between genetically determined inflammatory biomarkers and low back pain risk: a bidirectional two-sample Mendelian randomization study.

Background: Observational studies have suggested an association between inflammatory markers and low back pain (LBP), but the causal relationship between these factors remains uncertain.

Methods: We conducted a bidirectional two-sample Mendelian randomization analysis (MR) study to investigate whether there is a causal relationship between inflammatory markers and low back pain. We obtained genetic data for CRP, along with its upstream inflammatory markers IL-6, IL-8, and IL-10, as well as low back pain from publicly available genome-wide association studies (GWAS).

Effect of constant compressive stress induced by imitating Tuina stimulation with various durations on the cell cycle, cellular secretion, apoptosis, and expression of myogenic differentiation and myogenic factor 5 of rat skeletal muscle cells in vitro.

Objective: To investigate the effect of constant compressive stress induced by imitating Tuina stimulation with various durations on the cell cycle, cellular secretion, apoptosis, and expression of myogenic regulatory factors (MRFs), myogenic factor 5(Myf5) and myogenic differentiation (MyoD) of rat skeletal muscle cells (RSkMCs) in vitro.

Methods: Third passage RSkMCs were subjected to constant compressive stresses with various durations at 2000 strain for 15, 30, 60, 90, and 120 min via a four-point bending system. The control group (CG) was cultured in the absence of mechanical loading.

['s manipulations in the treatment of tendon syndrome].

The manipulation characteristic and experience in the treatment of tendon syndrome, by , the veteran TCM physician, were introduced in the article. The tendon syndrome is treated on the base of syndrome differentiation for the acupoint selection in the guidance of the theory on the tendon region of meridian in () and in accordance with the etiology and clinical characteristics of tendon syndrome. Focusing on the palpation and the responses under the fingers, as well as the application of warming method, the acupuncture (rubbing and twisting) and (relaxing, separating, warming and regulating) manipulations are adopted in combination on the positive points and the intermuscular spaces.

[Anterior-posterior acupoint combination for low back pain].

The meridian diseases, abnormal psoas and abdominal muscles and abdominal pressure are key causes of low back pain. We treat low back pain mainly with lumbar back area, neglecting abdomen. The anterior-posterior acupoint combination, regulating to treat is effective.

Sludge Biochar Amendment and Alfalfa Revegetation Improve Soil Physicochemical Properties and Increase Diversity of Soil Microbes in Soils from a Rare Earth Element Mining Wasteland.

Long-term unregulated mining of ion-adsorption clays (IAC) in China has resulted in severe ecological destruction and created large areas of wasteland in dire need of rehabilitation. Soil amendment and revegetation are two important means of rehabilitation of IAC mining wasteland. In this study, we used sludge biochar prepared by pyrolysis of municipal sewage sludge as a soil ameliorant, selected alfalfa as a revegetation plant, and conducted pot trials in a climate-controlled chamber.

Treatment of Ammonia Nitrogen Wastewater in Low Concentration by Two-Stage Ozonization.

Ammonia nitrogen wastewater (about 100 mg/L) was treated by two-stage ozone oxidation method. The effects of ozone flow rate and initial pH on ammonia removal were studied, and the mechanism of ammonia nitrogen removal by ozone oxidation was discussed. After the primary stage of ozone oxidation, the ammonia removal efficiency reached 59.

[Professor LUO Cai-gui's experience of using acupoint "Baliao" for treatment of low back pain].

Professor LUO Cai-gui's experience of acupuncture at acupoint "Baliao" with twisting manipulation for treatment of low back pain is introduced. This method has significant efficacy on improving low back pain and numbness of lower extremities, which is characterized with short-time manipulation, quick de-qi and long effective time. The acupuncture methods, manipulations, precautions, etc.

[Effect of hallux-trampling combined with Yaotongling suppository on microcirculation in treating lumbar intervertebral disc prolapse].

Objective: To observe the effect of hallux-trampling (HT) combined with Yaotongling suppository (YS) on the microcirculation at waist region and lower limbs in treating patients with lumbar intervertebral disc prolapse (LIDP), and to preliminarily explore its mechanism.

Methods: Adopting randomized, double-blinded medicine and single-blinded manipulation controlled method, 108 patients with LIDP of cold-accumulation and blood-stasis syndrome were assigned equally to 3 groups in random. Group A was treated with HT plus YS, Group B treated with HT plus placebo suppository, and Group C treated with YS plus mock HT.
