ABSTRACT
Chronic low back pain (CLBP) is a highly prevalent condition worldwide and a major cause of disability. The majority of patients with CLBP are diagnosed with chronic non-specific low back pain (CNLBP) due to an unknown pathological cause. Manual therapy (MT) is an integral aspect of traditional Chinese medicine and is recognized as Tuina in China. It involves techniques like bone-setting and muscle relaxation manipulation. Despite its clinical efficacy in treating CNLBP, the underlying mechanisms of MT remain unclear. In animal experiments aimed at investigating these mechanisms, one of the main challenges is achieving normative MT on CNLBP model rats. Improving the stability of finger strength is a key issue in MT. To address this technical limitation, a standardized procedure for MT on CNLBP model rats is presented in this study. This procedure significantly enhances the stability of MT with the hands and alleviates common problems associated with immobilizing rats during MT. The findings of this study are of reference value for future experimental investigations of MT.

To study the residue and dietary risk of propiconazole in Panax notoginseng and the effects on physiological and bioche-mical properties of P. notoginseng, we conducted foliar spraying of propiconazole on P. notoginseng in pot experiments. The physiolo-gical and biochemical properties studied included leaf damage, osmoregulatory substance content, antioxidant enzyme system, non-enzymatic system, and saponin content in the main root. The results showed that at the same application concentration, the residual amount of propiconazole in each part of P. notoginseng increased with the increase in the times of application and decreased with the extension of harvest interval. After one-time application of propiconazole according to the recommended dose(132 g·hm~(-2)) for P. ginseng, the half-life was 11.37-13.67 days. After 1-2 times of application in P. notoginseng, propiconazole had a low risk of dietary intake and safety threat to the population. The propiconazole treatment at the recommended concentration and above significantly increased the malondialdehyde(MDA) content, relative conductivity, and osmoregulatory substances and caused the accumulation of reactive oxygen species in P. notoginseng leaves. The propiconazole treatment at half(66 g·hm~(-2)) of the recommended dose for P. ginseng significantly increased the activities of superoxide dismutase(SOD), peroxidase(POD), and catalase(CAT) in P. notoginseng leaves. The propiconazole treatment at 132 g·hm~(-2) above inhibited the activities of glutathione reductase(GR) and glutathione S-transferase(GST), thereby reducing glutathione(GSH) content. Proconazole treatment changed the proportion of 5 main saponins in the main root of P. notoginseng. The treatment with 66 g·hm~(-2) propiconazole promoted the accumulation of saponins, while that with 132 g·hm~(-2) and above propiconazole significantly inhibited the accumulation of saponins. In summary, using propiconazole at 132 g·hm~(-2) to prevent and treat P. notoginseng diseases will cause stress on P. notoginseng, while propiconazole treatment at 66 g·hm~(-2) will not cause stress on P. notoginseng but promote the accumulation of saponins. The effect of propiconazole on P. notoginseng diseases remains to be studied.

Panax notoginseng is a perennial Chinese medicinal plant, which has serious continuous cropping obstacles and is prone to a variety of diseases and insect pests during the growth process. At present, the prevention and control of pests and diseases is mainly carried out through chemical pesticides, and the consequent pesticide residues of P. notoginseng have attracted much attention. This study reviewed the types and detection methods of pesticide residues in P. notoginseng from 1981 to 2021, and compared the limits of pesticide residues in P. notoginseng in China and abroad to provide a reference for rational application of pesticides in P. notoginseng and quality control of medicinal materials, thereby promoting the sustainable development of the P. notoginseng industry in China. Currently, there are only 40 published papers on pesticide residues of P. notoginseng, which is indicative of a serious problem of insufficient research. At present, hundreds of pesticide residues in P. notoginseng can be detected simultaneously by using chromatography-tandem mass spectrometry. The pesticides detected have gradually changed from early prohibited ones, such as dichlorodiphenyl trichloroethane(DDT), benzene hexachloride(BHC), and parathion, to low toxic ones(e.g., dimethomorph, procymidone, propicona-zole, and difenoconazole). The dietary risk from pesticide residues in P. notoginseng is low, which would not cause harm to consu-mers. This study concluded that in the future, the development of the quality standard for pesticide residues of P. notoginseng should be actively carried out. To increase the pesticides used in actual production in the quality standard based on the existing ones and to guide farmers to use pesticides scientifically will be the focus of future work.

Acrylamide (AA) is an organic chemical widely existing in the public diet, especially in foods with high-temperature fried and baked starchy and may have various adverse health effects on organisms. The purpose of this study was to investigate whether quercetin plays a protective role in AA-induced element variation in rats. Rats were randomly divided into the control group, AA-treated group [5 mg/kg body weight (bw)], two dosages of quercetin-treated groups (10 and 50 mg/kg·bw, respectively), and two dosages of quercetin plus AA-treated groups. After a 16-week treatment, the serum samples of rats were collected. Serum elements were analyzed by using inductively coupled plasma mass spectrometry (ICP-MS) combined with multivariate statistical analysis, and antioxidant indices, lipid peroxidation indicator, as well as inflammatory biomarkers, were also detected. The accuracy and precision of the method were verified, and all the validated data are within the satisfactory range. The results showed that the levels of vanadium (V), copper (Cu), zinc (Zn), selenium (Se), cobalt (Co), and magnesium (Mg) in serum were significantly lower (p < 0.01), while serum calcium (Ca) level was significantly higher (p < 0.01) in AA-treated group compared with the control group. When high-dose quercetin was administered to rats combined with AA, a significant recovered effect for the above elements levels was observed compared with the AA-treated group. This study suggests that quercetin (50 mg/kg·bw) exerts a regulatory and protective role in AA-induced variation of serum elements via reducing oxidative stress and inhibiting inflammation.

Chinese herbal formulas including the lung-cleaning and toxicity-excluding (LCTE) soup have played an important role in treating the ongoing COVID-19 pandemic (caused by SARS-CoV-2) in China. Applying LCTE outside of China may prove challenging due to the unfamiliar rationale behind its application in terms of Traditional Chinese Medicine. To overcome this barrier, a biochemical understanding of the clinical effects of LCTE is needed. Here, we explore the chemical compounds present in the reported LCTE ingredients and the proteins targeted by these compounds via a network pharmacology analysis. Our results indicate that LCTE contains compounds with the potential to directly inhibit SARS-CoV-2 and inflammation, and that the compound targets proteins highly related to COVID-19's main symptoms. We predict the general effect of LCTE is to affect the pathways involved in viral and other microbial infections, inflammation/cytokine response, and lung diseases. Our work provides a biochemical basis for using LCTE to treat COVID-19 and its main symptoms.

OBJECTIVE: To evaluate the effect of shuxuetong (SXT) in preventing restenosis after intracoronary stenting. METHODS: Sixty-eight patients, accepted intracoronary stenting, were divided into two groups, the SXT group and the control group, both of them were treated with conventional treatment, and to the SXT group, SXT was given additionally. The condition of treated coronary artery restenosis in the two groups was compared by way of quantitative coronary angiography and a 6-month follow-up study was adopted. RESULTS: Follow-up study was completed in 43 patients (23 cases in the SXT group, and 20 in the control group). The angina recurrence rate in the SXT group (3 cases, 13%) was significantly lower than that in the control group (7 cases, 35%, P < 0.05). Quantitative coronary angiography showed the restenosis degree of operated artery in the SXT group was significantly milder than that in the control group, with the last lumen losing and index in the SXT group (0.46 +/- 0.25 mm, 24.26 +/- 8.64%) less than those in the control group (0.75 +/- 0.33 mm, 31.25 +/- 11.03%). The net gain lumen and the net gain index in the SXT group (1.23 +/- 0.30 mm, 58.96 +/- 24.68%) were greater than those in the control group (0.98 +/- 0.33 mm, 42.68 +/- 29.51%), all P < 0.05. But the restenosis rate in the two groups was insignificantly different (P > 0.05). CONCLUSION: SXT might has some definite effect in preventing restenosis after intracoronary stenting.
