ObjectiveTo establish a quality evaluation method for Zhuye Shigao granules（Zhuye Shigaotang） based on fingerprint and determination of index components， and to investigate the therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome. MethodsThe fingerprint of Zhuye Shigao granules was established by high performance liquid chromatography（HPLC）， and the methods for determination of total calcium， orientin， isoorientin， ginsenosides Rg₁， Re and Rb₁ and other 2 index components were established. Fifty ICR mice were randomly divided into the blank group， model group， Zhuye Shigao granules low， medium and high dose groups（9.3， 18.6， 37.2 g·kg^-1·d^-1）， with 10 mice in each group. In addition to the blank group， the model mice with cold-dampness pestilence attacking lung syndrome was prepared by nasal drip of lipopolysaccharide combined with cold-dampness environment. Each administration group was given the corresponding liquid by gavage according to the dose， while the blank group and model group were given the same volume of normal saline by gavage. Then， the body temperature and organ index of mice in each group were measured， hematoxylin-eosin（HE） staining was used to investigate the lung tissue injury of mice in each group， and enzyme-linked immunosorbent assay（ELISA） was used to detect the changes of tumor necrosis factor-α（TNF-α）， interleukin（IL）-lβ， IL-6， IL-10 levels in serum and lung tissue， as well as immunoglobulin（Ig）A and IgM levels in serum. ResultsThe fingerprint similarity of 10 batches of Zhuye Shigao granules was>0.950， and 20 common peaks were calibrated. Seven of them were identified， including peak 11（isoorientin）， peak 12（orientin）， peak 14（apioside liquiritin）， peak 15（liquiritin）， peak 17（apioside isoliquiritin）， peak 19（isoliquiritin） and peak 20（liquiritigenin）. The results of quantitative analysis showed that the content range of each index component in 10 batches of Zhuye Shigao granules was as follows：Total calcium of 9.978-11.294 mg·g^-1， isoorientin of 0.033-0.041 mg·g^-1， orientin of 0.046-0.055 mg·g^-1， ginsenoside Rg₁+ginsenoside Re of 0.748-0.762 mg·g^-1， ginsenoside Rb₁ of 0.151-0.197 mg·g^-1， liquiritin of 1.106-1.366 mg·g^-1， glycyrrhizic acid of 0.904-1.182 mg·g^-1_. Compared with the blank group， the body temperature of mice in the model group was significantly increased， the organ indexes of liver， lung and spleen were significantly decreased， the organ index of thymus was significantly increased， HE staining of lung tissue showed infiltration of inflammatory cells， a small amount of serous exudation was observed in the alveoli， and lung tissue was damaged. After the intervention of Zhuye Shigao granules， the pathological changes were improved compared with the model group. The expression levels of IL-1β， IL-6 and TNF-α were significantly increased， the expression level of IL-10 was significantly decreased in serum and lung tissue. The levels of IgA and IgM in serum were significantly decreased（P<0.01）. Compared with the model group， the body temperature， the organ indexes and immune factor levels in serum and lung tissue of mice in the Zhuye Shigao granules medium and high dose groups were significantly reduced（P<0.05， P<0.01）. ConclusionIn this study， the quality evaluation of Zhuye Shigao granules was carried out based on fingerprint combined with determination of index components， and the fingerprint of four herbs（Lophatheri Herba， Ophiopogonis Radix， Pinelliae Rhizoma and Glycyrrhizae Radix et Rhizoma） in this formula and the determination of 8 index components were established. The therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome may be related to inhibiting inflammatory response and mediating immune regulation.

ObjectiveTo clarify the neuroprotective effect of black Panacis Quinquefolii Radix（PQR） and explore its active ingredients， with the aim of establishing an activity-oriented quality evaluation method. MethodsTransgenic Tg（HuC∶EGFP） zebrafish was used to establish a neuronal injury model by aluminum chloride immersion. Different doses（10， 20 mg·L^-1） of PQR and black PQR ethanol extracts were administered. The neuroprotective effects of PQR and black PQR were compared by analyzing the fluorescent area and intensity of zebrafish neurons. Based on ultra-performance liquid chromatography（UPLC）， a fingerprint profile of black PQR was established， followed by principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）. Differential components were screened using the criteria of variable importance in the projection（VIP） value>1 and P<0.05. The neuroprotective activity of 14 batches of black PQR was assessed， and Spearman correlation analysis was used to identify saponins related to neuroprotective activity， which were then validated. Based on the above results， active marker components were determined， and an UPLC method was established for their quantitation with clear content limits. ResultsPharmacological efficacy results showed that both PQR and black PQR at different doses could significantly improved neuronal damage in zebrafish. At a dose of 20 mg·L^-1， black PQR demonstrated superior efficacy（P<0.05）. The fingerprint similarities of 14 batches of black PQR were>0.94， with 26 common peaks identified. Through comparison with the reference standards， 8 components were confirmed， including peak 1（ginsenoside Rg₁）， peak 2（ginsenoside Re）， peak 5（ginsenoside Rb₁）， peak 9（ginsenoside Rd）， peak 16［ginsenoside 20（S）-Rg₃］， peak 17［ginsenoside 20（R）-Rg₃］， peak 18（ginsenoside Rk₁）， and peak 19（ginsenoside Rg₅）. The results of PCA and OPLS-DA indicated that there were differences in saponins among black PQR samples from different origins， and 12 differential components were screened. All 14 batches of black PQR exhibited good protective effects on zebrafish neurons， with Shaanxi-produced black PQR showing superior protective effects compared to the other three production regions. Spearman correlation analysis revealed that a total of 11 components， including ginsenosides 20（S）-Rg₃， 20（R）-Rg₃， Rk₁ and Rg₅， showed a significant positive correlation with the neuroprotective effect in zebrafish（P<0.05）. The activity validation results indicated that ginsenosides 20（S）-Rg₃， 20（R）-Rg₃， Rk₁ and Rg₅ were the primary components responsible for the neuroprotective effects of black PQR. Quantitative analysis showed that the content of ginsenoside 20（S）-Rg₃ in 14 batches of black PQR ranged from 0.17% to 0.52%， and the repair rate of neuronal damage ranged from 42.77% to 97.83%. ConclusionBased on the fingerprint and neuronal protective activity， the spectrum-effect related quality control model of black PQR was established， with ginsenoside 20（S）-Rg₃ as the quality control index， and the neuronal damage repair rate≥60% as the evaluation standard， the minimum limit of ginsenoside 20（S）-Rg₃ in black PQR should be≥0.20%.

ObjectiveTo assess the quality consistency of black Panacis Quinquefolii Radix（bPQR） decoction pieces prepared by atmospheric and pressurized steaming processes based on chromaticity-chemical composition-vasoactive inhibition. The ultimate goal was to screen the pressurized steaming process yielding quality equivalent to atmospheric steaming， and optimize the processing technology of bPQR. MethodsThe bPQR decoction pieces were prepared using both atmospheric and pressurized steaming processes， and the chromaticity values［lightness value（L^*）， red/green chromaticity value（a^*）， yellow/blue chromaticity value（b^*）， total chromaticity value（E^*ab）］ were measured. High performance liquid chromatography（HPLC） was employed to establish fingerprint profiles for the decoction pieces， and cluster analysis was conducted on chromaticity values and the common peak areas in fingerprint profiles to elucidate the quality relationships between the decoction pieces processed by different methods. The optimal atmospheric steaming of bPQR decoction pieces was determined through zebrafish angiogenesis inhibition experiments. The contents of ginsenosides Rg₁， Re， Rb₁， 20（S）-Rg₃， Rk₁ and Rg₅ in the decoction pieces were quantified， and Spearman correlation analysis was employed to investigate the relationship between saponin content， chromaticity， and angiogenesis inhibition activity during the steaming process. By integrating the consistency of chromaticity， saponin components and angiogenesis inhibition activity， pressurized steaming conditions with quality equivalent to the atmospheric pressure method were selected. ResultsCompared with the atmospheric steaming method， pressurized steaming resulted in faster color darkening and higher conversion rates of ginsenosides in bPQR decoction pieces. Moreover， the neovascularization inhibitory activity of bPQR decoction pieces continued to increase with the deepening of processing. Based on the effectiveness and safety， the optimal process for preparing bPQR decoction pieces with neovascularization inhibitory activity was determined to be atmospheric steaming for 21 h. All six ginsenosides tested exhibited strong to extremely strong correlations with both the chromaticity values of the decoction pieces and their neovascularization inhibitory activities. Among them， ginsenosides Rg₁， Re and Rb₁ exhibited positive correlations with chromaticity values and negative correlations with zebrafish angiogenesis inhibition activity. Conversely， ginsenosides 20（S）-Rg₃， Rk₁ and Rg₅ showed negative correlations with chromaticity values and positive correlations with zebrafish angiogenesis inhibition activity. By integrating chromaticity values， cluster analysis results， as well as the results of activity， it was determined that the quality of bPQR decoction pieces steamed under pressurized conditions of 110 ℃（0.045 MPa） for 5 h and 115 ℃（0.07 MPa） for 3 h was highly consistent with that obtained by atmospheric steaming for 21 h. ConclusionThe preparation of bPQR decoction pieces by pressurized steaming has the advantages of short preparation time， low energy consumption， and rapid saponin conversion rate， making it a viable alternative to atmospheric steaming for preparing bPQR decoction pieces. Meanwhile， the evaluation method based on chromaticity-chemical composition-activity can provide a more scientific and effective explanation of change rules in the quality during traditional Chinese medicine processing， and offer a new model for optimizing processing technology and enhancing quality control.

ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C₁₈ column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg₁， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb₁， Rc ， Rb₂ and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg₁， Re， Rb₁ and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb₂ and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg₁， Rb₁， Rc， Rb₂ and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.

ObjectiveTo analyze and determine the differential components of freeze-dried and sun-dried Panacis Quinquefolii Radix（PQR）， and to compare the differences in their pro-angiogenic activities. MethodFingerprints of freeze-dried and sun-dried PQR were established based on ultra performance liquid chromatography（UPLC）， and chemometrics methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were combined to determine the differential saponin composition of the two decoction pieces， and six representative saponins were selected and their contents in freeze-dried and sun-dried PQR were determined by UPLC. Transgenic zebrafish line Tg（fli1a∶EGFP） embryos fertilized for 24 h were selected， and different doses of 70% methanol extracts of freeze-dried and sun-dried PQR（10， 30 mg·L^-1） were used to intervene in normal zebrafish and in a zebrafish model of intersegmental vascular（ISV） injury induced by vascular endothelial growth factor（VEGF） receptor tyrosine kinase inhibitor Ⅱ（PTK787）， then the development of subintestinal vein（SIV） and ISV of zebrafish was observed， SIV diameter， mean number of crossings and mean number of germinations were determined， and the ISV vascular index was calculated， in order to compare the pro-angiogenic activities of the two decoction pieces. ResultThe similarity of the fingerprints of freeze-dried and sun-dried PQR decoction pieces was>0.950， and 17 common peaks were identified， of which 6 common peaks were designated as peak 6（ginsenoside Rg₁）， peak 7（ginsenoside Re）， peak 8（ginsenoside Rb₁）， peak 11（ginsenoside Rc）， peak 13（ginsenoside Rb₂）， and peak 16（ginsenoside Rd）， respectively. A total of 11 differential saponin components were screened by PCA and OPLS-DA， indicating that there were some differences in the contents of the components in the two decoction pieces. The results of determination showed that the contents of ginsenosides Rg₁， Re， Rb₁ and Rb₂ in freeze-dried PQR were higher than those in sun-dried PQR， while the contents of ginsenosides Rc and Rd were lower than those in sun-dried PQR（P<0.05， P<0.01）. In the study of the pro-angiogenic effect on normal zebrafish embryos， compared with the blank group， and the SIV vessel diameter， mean germination rate and mean crossover rate were significantly higher in the high-dose groups of freeze-dried and sun-dried PQR（P<0.01）， and the vessel diameter， mean numbers of crossings and germinations in the freeze-dried PQR group were higher than those of the sun-dried PQR group（P<0.05）. In the study of the pro-angiogenic effect on zebrafish embryos with ISV injury， the development of ISV in the model group was significantly inhibited when compared with the blank group， compared with the model group， different dose groups of freeze-dried and sun-dried PQR could promote the growth and sprouting of ISV， and the number of normal blood vessels in the freeze-dried PQR group was significantly higher than that in the sun-dried PQR group at the same dosage（P<0.05）. ConclusionFreeze-drying can effectively avoid the loss and secondary transformation of ginsenosides in PQR， and its angiogenic activity is better than that of sun-dried PQR， which can provide a reference for the production and development of high-quality PQR decoction pieces.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.
