ObjectiveTo establish fingerprint profiles and a quantitative determination method for Lycii Cortex, providing a scientific basis for the formulation of quality standards for Lycii Cortex and its roasted products. MethodsHigh performance liquid chromatography(HPLC) was developed for the quantitative method for determining kukoamine B in Lycii Cortex and its roasted products on an Alphasil XD-C18 CH column(4.6 mm×250 mm, 5 μm). HPLC fingerprint profiles were established for 10 batches of Lycii Cortex and its roasted products, and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to identify the common peaks based on reference standards, literature and MS information. Quality evaluation indicators included yield of decoction pieces, appearance properties, content of kukoamine B, and fingerprint profiles. The temperature and time of the roasting process were investigated to select the optimal preparation process, which was then verified. Additionally, chemical pattern recognition was combined to assess the differences in the chemical composition of Lycii Cortex before and after roasting, as well as among samples from different origins. ResultsQuantitative analysis indicated that the contents of kukoamine B in Lycii Cortex and its roasted products were 0.35%-5.51% and 0.24%-4.15%, respectively. The transfer rate of kukoamine B was 58.6%-78.9% after roasting. The fingerprint profile analysis demonstrated that the method established in this study effectively separated kukoamine B from other components in the samples and distinctly differentiated it from its impurity peak, cis-N-caffeoylputrescine. The HPLC fingerprint profiles of Lycii Cortex and its roasted products showed high similarity(all above 0.95), with 7 common peaks identified and five common components, including kukoamine B, cis-N-caffeoylputrescine, N-coumaroyl tyramine, feruloyltyramine, and glucosyringic acid, confirmed. Process optimization confirmed that baking at 110 ℃ for 20 min was a stable and feasible method for roasting Lycii Cortex. Principal component analysis and cluster analysis showed that there was little difference in the chemical composition between raw and roasted Lycii Cortex, but the quality of Lycii Cortex from different origins differed greatly. ConclusionThis study successfully established the fingerprint profiles and a quantitative method for the effective component kukoamine B in Lycii Cortex and roasted Lycii Cortex. The qualitative and quantitative analyses clarified that the impact of the roasting process on the chemical composition of Lycii Cortex was less significant than the variations due to its geographical origin. The findings of this study offer a reference for the development of quality evaluation methods and the establishment of quality standards for Lycii Cortex and its processed products.

Objective To understand the equity and influencing factors of maternal health service utilization in Changning District, Shanghai. Methods A convenience sampling method was used to conduct a questionnaire survey among mothers of children aged 1 to 1.5 years old who received health services from the child health care clinics and EPI clinics of 10 community health service centers in Changning District, Shanghai from March to April 2022. Count data was expressed by frequency and percentage. Chi-square analysis, binomial logistic regression analysis, and multivariate logistic regression analysis were used to analyze fairness-related factors. Rate difference, rate ratio and concentration index were used to represent fairness. Results A total of 696 subjects were investigated, with an average age of (33.35±4.76) years. There were statistically significant differences in service utilization among women with different household registrations only in early pregnancy registration (χ2=11.026, P=0.001) and postpartum visits (χ2=4.989, P=0.026). Women with a career showed differently in folic acid supplement (χ2=6.247, P=0.012), early pregnancy registration (χ2=12.989, P=0.002), physical examination in 42 days postpartum (χ2=4.446, P=0.035) and postpartum contraception (χ2=4.061, P=0.044), and the differences were statistically significant. Women with different monthly family income had a statistically significant difference in pre-pregnancy examination (χ2=8.977, P=0.030) and postpartum visit (χ2=16.114, P=0.001). There was a statistically significant difference between women with maternity insurance or not in the early pregnancy registration (χ2=10.576, P=0.001) and physical examination in 42 days postpartum (χ2=8.166, P=0.004). The results of the multivariate analysis showed that occupation (OR=2.616, 95% CI: 1.142-5.990) and maternity insurance (OR=4.490, 95% CI: 1.992~10.120) affected the utilization of service in early pregnancy registration. The monthly household income (OR=0.278, 95% CI: 0.124-0.625) affected the utilization of services in postpartum visit. At the same time, the monthly household income (10,000-19,999: OR=0.286, 95% CI: 0.090-0.907; ≥30,000: OR=0.180, 95% CI: 0.041-0.801) also affected the utilization of service in physical examination in 42 days postpartum. Conclusion The equity of maternal health care service utilization overall is good in central area in Shanghai, but there is still room for improvement. It is necessary to strengthen community mobilization, propagandize maternal health services, and expand the coverage of maternity insurance to improve the equity of maternal health service utilization and provide equal access to maternity health services.

ObjectiveTo clarify the pharmacodynamic characteristics and neuroinflammatory mechanisms of Ruyi Zhenbaowan (RYZBW) in treating nociceptive hypersensitivity and central sensitisation of spinal cord in the mouse model of central post-stroke pain (CPSP). MethodSPF-grade male ICR mice of 8 weeks old were assigned into the sham operation (Sham), model (CPSP), low-, medium-, and high-dose (0.303, 0.607 1.214 g·kg-1) RYZBW (RYZBW-L, RYZBW-M, and RYZBW-H, respectively), and pregabalin (PGB, 0.046 g·kg-1, positive control) groups. The rat model of CPSP was established by injection of type Ⅳ collagenase into the ventral posterior lateral nucleus of the thalamus on day 1. Rats were administrated with corresponding drugs or normal saline (Sham and CPSP groups) by gavage from day 14 to day 17. The mechanical pain sensitivity test was performed on days 0, 3, 4, 7, 10, 14, 17. On day 18, the L5 segment of spinal cord was collected for the detection of inflammatory cytokines by immunoinflammatory microarray, CXC chemokine ligand 16 (CXCL16) by enzyme-linked immunosorbent assay, and calcitonin gene-related peptide (cGRP) by immunohistochemistry. In addition, fluorescence dual-labeling was employed to determine the expression levels of CXCL16, the dendritic cell marker CD11c, the macrophage marker CD68, the microglia marker TMEM119, the endothelial cell markers CD31 and CXCR6, and the T cell marker CD3. ResultCompared with the Sham group, the mechanical pain threshold of the CPSP group was significantly lower than that of the Sham group from day 3 to day 17, with stable hyperalgesia symptoms. On the 7th day, the mechanical pain threshold of the PGB group was significantly higher than that of the CPSP group, with significant analgesic effect (P<0.01). On days 10-17, the mechanical pain threshold of the RYZBW-H group was significantly higher than that of the CPSP group, showing a stable analgesic effect (P<0.05). On the 17th day, the analgesic effect of RYZBW was dose-effect correlated (R2=0.303 7). From day 4 to day 17, the mechanical pain threshold of RYZBW-H group was positively correlated with time (R2=0.111 5). The above results suggested that the analgesia of RYZBW was time-dependent. On the 17 th day, the expression of central sensitization marker cGRP in the spinal dorsal horn of CPSP mice was significantly increased compared with the Sham group (P<0.05), and RYZBW down-regulated it in a dose-dependent manner (R2=0.500 8), suggesting that RYZBW significantly inhibited the central sensitization of the spinal cord caused by CPSP. The results of spinal cord inflammation chip on the 17th day showed that compared with CPSP group, RYZBW-H group inhibited CXCL16 expression (P<0.01).The results of ELISA based on independent repeated samples showed that RYZBW inhibited the expression of CXCL16 protein in spinal cord in a dose-dependent manner (R2=0.250 4). The results of immunofluorescence double labeling showed that compared with Sham group, the expression of CXCL16 in CD11c positive dendritic cells in CPSP group increased, and the number of CD68 positive cells increased (P<0.05). Compared with CPSP group, RYZBW down-regulated it: the expression of CXCL16 in CD31 positive endothelial cells, CD68 positive macrophages and TMEM119 positive microglia increased, and the number and cell body area of TMEM119 positive microglia increased significantly (P<0.05). The number of CD3 positive T cells (P<0.05) and the expression of CXCR6 in CD3 positive T cells were increased. RYZBW inhibited the activation of endothelial cells and macrophages in a dose-dependent manner, and reduced the infiltration of microglia and T cells (R2=0.691 4, R2=0.551 5, R2=0.653 2, R2=0.180 6, R2=0.287 5, R2=0.298 6,R2=0.511 6). ConclusionRYZBW can effectively alleviate nociceptive hypersensitivity and central sensitisation of the spinal cord in CPSP mice by regulating CXCL16-CXCR-6, inhibiting the infiltration and activation of microglia and macrophages, and the activation of dendritic cells, endothelial cells, and T cells.

Jinlingzi San is a formula frequently used in treating pain syndrome, first recorded in the Collection of Writings on the Mechanism of Disease, Suitability of Qi, and the Safeguarding of Life as Discussed in the 'Basic Questions' written by LIU Wansu in the Jin Dynasty. Jinlingzi San is composed of 2 Chinese medicinals Toosendan Fructus and Corydalis Rhizoma with a concise composition and exact clinical efficacy, having been included in the Catalogue of Ancient Classical Formulas (Second Batch: Han Chinese Medicine). The formula name, historic evolution, medicine origins, composition, dosage, decocting methods, and ancient and modern clinical application were sorted out and analyzed with the bibliometric method. A total of 209 pieces of information were collected from ancient books and literature. After screening, 49 pieces of effective data involving 45 ancient books were included. Results showed that the name of Jinlingzi San was first recorded in Secret Formulas of the Yang Family written by Yang Tan in the Southern Song Dynasty and developed into 3 other versions of the decoction. The Jinlingzi San included in the Collection of Writings on the Mechanism of Disease, Suitability of Qi, and the Safeguarding of Life as Discussed in the 'Basic Questions' written by LIU Wansu invariably plays a dominant role. As for the 3 other versions, although they have the same name of Jinlingzi San, their composition and indications are different from those of the original formula, which were therefore viewed as prescriptions based on Jinlingzi San and also included in the research. The medicine origins and processing of Jinlingzi San are suggested: Toosendan Fructus is the dry mature fruit of Melia toosendan of Meliaceae, and the crude is used after cleansing without putamen. Corydalis Rhizoma is the dry tuber of Corydalis yanhusuo of Papaveraceae, which is used after impurity removal, cleaning, and drying. Depending on the conversion from the measurement system in the Jin Dynasty to modern measurement, it is suggested that Toosendan Fructus and Corydalis Rhizoma (41.3 g each) are ground into fine powder, and one dose includes 12.39 g of the powder, which should be taken with an appropriate amount of wine. If wine is not suitable for the patient, the decoction can also be taken with warm water. Jinlingzi San has the effects of soothing the liver, discharging heat, and activating blood to stop pain. As recorded in ancient books, Jinlingzi San is specialized in treating heart pain caused by reversal heat, chest and abdominal pain, hypochondriac pain, jaundice, hernia, and other diseases. Modern studies have shown that modified Jinlingzi San can be used in treating diseases involving the digestive system, the integumentary system, the gynecological system, the reproductive system, and other systems and has wide clinical application in treating epigastric pain, herpes zoster, dysmenorrhea, and other diseases. This study has made clear the key information of Jinlingzi San by textual research of ancient books and literature in the hope of providing a theoretical reference for the clinical application, set prescriptions, and new drug development.

Talents are the main force for the development of traditional Chinese medicine(TCM), and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present, we are still exploring and developing in the fields of the formulation, implementation and evaluation indicators of TCM talent evaluation system. However, there are shortcomings and difficulties. For instance, insufficient stratification in the evaluation, excessive emphasis on the quantity of achievements, neglecting the quality of the achievements and the actual contribution, imperfect assessment indicators, and the weak characteristics of TCM. Therefore, national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard, in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value, ability and contribution. For the evaluation of TCM clinical talents, China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM(CCCL-TCM), which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry, and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.
