ABSTRACT

ObjectiveTo investigate rehabilitation competence among trainers and trainees whom participated in the training program entitled National Training Program of Shortage Rehabilitation Physicians (NTPSRP) using World Health Organization rehabilitation competency framework (RCF). MethodsBased on RCF, a questionnaire was developed and administrated through network using Questionnaire Star. All the trainers and trainees who participated in NTPSRP were investigated in September, 2023. ResultsA total of 911 subjects were collected from 27 provinces, including 426 trainers (teachers) and 485 trainees (students). The average age of the teachers was older, with more years of work experience and professional experience in rehabilitation medicine. The degree and professional title of the teachers was also higher. The overall internal consistency reliability of the questionnaire was good (Cronbach's α = 0.988), and all the internal consistency reliability in five fields was good (Cronbach's α > 0.9). The five dimensional structure of RCF in the results was consistent with the prior model established by RCF theory. The self-ratings of all physicians in the five fields were higher than the median level, and was higher in the teachers than in the students [(3.42±0.68) vs. (2.73±0.80), P < 0.001]. Gender and years of experience in rehabilitation medicine were independent factors for the total score of the questionnaire. The total self-rating of female students was 9.65 points lower than that of the male (95%CI 4.386 to 14.914); and one more year in rehabilitation medicine would increase 1.78 points in self-rating (95%CI 1.140 to 2.419). ConclusionThe structure and content of RCF can be used to evaluate the competence of rehabilitation physicians. The teachers and students of NTPSRP are eligible to RCF. RCF-based evaluation can be used to guide the development of continuing education courses for rehabilitation professionals.

ABSTRACT

Pulmonary endothelial barrier dysfunction is a hallmark of clinical pulmonary edema and contributes to the development of acute lung injury (ALI). Here we reported that ruscogenin (RUS), an effective steroidal sapogenin of Radix Ophiopogon japonicus, attenuated lipopolysaccharides (LPS)-induced pulmonary endothelial barrier disruption through mediating non-muscle myosin heavy chain IIA (NMMHC IIA)‒Toll-like receptor 4 (TLR4) interactions. By in vivo and in vitro experiments, we observed that RUS administration significantly ameliorated LPS-triggered pulmonary endothelial barrier dysfunction and ALI. Moreover, we identified that RUS directly targeted NMMHC IIA on its N-terminal and head domain by serial affinity chromatography, molecular docking, biolayer interferometry, and microscale thermophoresis analyses. Downregulation of endothelial NMMHC IIA expression in vivo and in vitro abolished the protective effect of RUS. It was also observed that NMMHC IIA was dissociated from TLR4 and then activating TLR4 downstream Src/vascular endothelial cadherin (VE-cadherin) signaling in pulmonary vascular endothelial cells after LPS treatment, which could be restored by RUS. Collectively, these findings provide pharmacological evidence showing that RUS attenuates LPS-induced pulmonary endothelial barrier dysfunction by inhibiting TLR4/Src/VE-cadherin pathway through targeting NMMHC IIA and mediating NMMHC IIA‒TLR4 interactions.

ABSTRACT

Osteoarthritis (OA),a common chronic degenerative joint disease,rises gradually with age,which seri-ously affects the quality of life of middle-aged and elderly patients. Currently,the therapeutic medications such as nonsteroidal anti-inflammatory drugs (NSAIDs)and analgesics might improve OA symptoms,but cannot prevent the development of OA. The active ingredients of traditional Chinese medicine (TCM)have unique advantages in the treatment of OA. This article reviews the research progress of active ingredients of TCM in the prevention and treatment of OA reported by domestic and foreign journals in the past five years from the aspects of inhibition of the secretion of inflammation-related factors,improvement of cartilage matrix synthesis and catabolic imbalance, inhibition of chondrocyte apoptosis,promotion of chondrocyte proliferation,and regulation of estrogen levels,with an attempt to provide a theoretical basis for the development of new drugs for OA.

ABSTRACT

@#The aim of the present study was to investigate the effects of levo-corydalmine(l-CDL)on chronic constrictive injury(CCI)-induced neuropathic pain and central sensitization in spinal cord. The mechanical withdrawal threshold in rats was assessed by Von-Frey fibers and the thermal withdrawal latency was assessed by thermal stimulus apparatus. The level of phosphorylated N-methyl-D-aspartic acid receptor 1(NR1)in L4-L6 spinal cord was analyzed by immunoblotting and the expression of calcitonin gene related peptide(CGRP)and c-fos in spinal cord dorsal horn were analyzed by immunofluorescence. Results showed that l-CDL(7. 5, 15, 30 mg/kg, ig)inhibited CCI-induced mechanical allodynia and thermal hyperalgesia in a dose-dependent manner. l-CDL significantly inhibited the up-regulation of p-NR1, c-fos and CGRP in CCI rats without tolerance. In conclusion, l-CDL has a good relieving effect on central sensitization in spinal cord, thus generating outstanding analgesic activity on CCI-induced neuropathic pain.

ABSTRACT

@#Two simple and efficient methods have been developed for screening and identification of natural peroxynitrite scavengers in Radix Scrophulariae (RS). Method I was based on HPLC-DAD-(luminol-peroxynitrite)-CL techniques combined with Q-TOF MS/MS analysis, while method II was based on the pre-column reaction with peroxynitrite followed by HPLC separation with Q-TOF MS/MS analysis. Five active constituents, P1(decaffeoylacteoside), P9(eoside), I6(6″-O-feruloylharpagide), P11(cis-acteoside)and P13(angoroside), were found to possess potential peroxynitrite-scavenging activity by method I, while P9 and P13 were also screened by method II. Method I requires more complex apparatus, but has advantages on simple detection and high sensitivity. Method II requires simpler apparatus than method I, but with more tedious detection and lower sensitivity. However, the methods established above would provide new ways for rapid detection of natural peroxynitrite-scavenging compounds in RX complex matrices.

ABSTRACT

OBJECTIVE:To explore the content variation rule and influencing factors of 5-hydroxymethylfurfural(5-HMF)in the extraction process of the herbs Schisandra chinensis and improve the quality of monitoring the extract of Schisandra chinensis. METHODS:High performance liquid chromatography was adopted to determine the contents of 5-HMF in the extracts during the extraction process (decoction,vacuum concentration,alcohol precipitation,vacuum drying,alkali adjustment),and the content variation rule was found out. For vacuum drying during which the content of 5-HMF reduced obviously,the effects of the tempera-ture and time of drying on the content of 5-HMF were studied,and the effects of vacuum drying and freeze drying on the 5-HMF contents were compared. RESULTS:The content variation trend in the extraction process of Schisandra chinensis was as follows as a large amount of 5-HMF was produced in the herbs decoction process;the content of 5-HMF increased during concentration,re-duced during the alcohol precipitation and the vacuum drying of the extracts by three times concentrate,and maintained substantial-ly unchanged during alkali adjustment. In the process of vacuum drying,the content of 5-HMF decreased with temperature rise and time extension. Freeze drying had no effect as good as that of vacuum drying in the reduction in the content of 5-HMF. CON-CLUSIONS:It is suggested that the vacuum drying of the extracts by three times concentrate at higher temperature,which may pro-duce the extract of Schisandra chinensis with lower content of 5-HMF and thus improve the quality of Schisandra chinensis extract.

ABSTRACT

The study aims to develop a unified method to determine seven phenolic acids (neochlorogenic acid, chlorogenic acid, 4-caffeoylquinic acid, caffeic acid, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C) contained in honeysuckle flower that is the monarch drug of all the eight Yinqiao Jiedu serial preparations using quantitative analysis of multi-components by single-marker (QAMS). Firstly, chlorogenic acid was used as a reference to get the average relative correction factors (RCFs) of the other phenolic acids in ratios to the reference; columns and instruments from different companies were used to validate the durability of the achieved RCFs in different levels of standard solutions; and honeysuckle flower extract was used as the reference substance to fix the positions of chromatographic peaks. Secondly, the contents of seven phenolic acids in eight different Yinqiao Jiedu serial preparations samples were calculated based on the RCFs durability. Finally, the quantitative results were compared between QAMS and the external standard (ES) method. The results have showed that the durability of the achieved RCFs is good (RSD during 0.80% - 2.56%), and there are no differences between the quantitative results of QAMS and ES (the relative average deviation < 0.93%). So it can be successfully used to the quantitative control of honeysuckle flower principally prescribed in Yinqiao Jiedu serial preparations.
