A comprehensive HPLC-DAD-MS method was developed to study the chemical components of semi-bionic extract of Coptis-Evodia herb couple. The extract was isolated on a Hypersil BDS C18 column (4.6 mm x 200 mm, 5 microm) using acetonitrile-ammonium formic buffer as mobile phase by gradient elution. Detection was performed on DAD and MS equipped with an electrospray ionization (ESI) source by full scan and product full scan on positive mode. The chromatogram of Coptis-Evodia showed seventeen main peaks, eight of which were from Evodia while the others were from Coptis. By comparison of the retention time, the on-line UV spectra and MS spectra, four peaks were identified as jatrorrhizine, hydroxevodiamine, palmatine and berberine, and three peaks were deduced as epiberberine, columbamine and coptisine. In addition, berberine and palmatine were quantitatively determined. No new component was created in the semi-bionic extract of the herb couple, yet the solubilities of berberine and palmatine decreased.

OBJECTIVE To explore the protective effects and mechanisms of Ginsenoside Rg1 (Rg1) on H2O2-induced hippocampal neurons aging in vitro. METHODS The primary culture hippo-campal neurons(7 d)were randomly placed into six groups:normal control group,H2O2(200 μM)treat-ment group,and H2O2+Rg1(1,5 and 10μM)groups.The neurons were with Rg1(1,5 and 10 μmol·L-1) for 6h. H2O2(200 μmol·L-1) was added to the medium and incubate for 18 h. The Dihydroethidium (DHE) staining was performed for ROS production assessment. The LDH release and Hoechst 33258 were performed to examine the neuronal damage and apoptosis. The immunoblot was used to deter-mine the expression of β-Gal,NOX2,p22phox,p47phox,NLRP-1,ASC and Caspase-1 in hippocampal neurons.The ELISA was performed to detect the levels of IL-1β and IL-18 released in the supernatant in hippocampal neurons.RESULTS Rg1(5 and 10 μmol·L-1)significantly reduced the ROS production, attenuated H2O2-induced neuronal damage and apoptosis (P<0.05, P<0.01). The immunoblot results showed that Rg1(5 and 10 μmol·L-1)treatment significantly decreased the expression of β-Gal,NOX2, p22phox,p47phox,NLRP-1,ASC and Caspase-1 in hippocampal neurons(P<0.05,P<0.01).Additionally, Rg1(5 and 10 μmol·L-1)treatment significantly decreased IL-1β and IL-18 release in the supernatant. CONCLUSION The protective effect of Rg1 in H2O2-induced hippocampal neurons aging may be due to inhibit NOX2-NLRP1 activation.

OBJECTIVES: To assess the growth of preterm infants up to a corrected age of 24 months, and to understand the growth trend and pattern of preterm infants. METHODS: A preterm infant follow-up database was established based on the Internet Plus follow-up system. A total of 3 188 preterm infants who were born from April 2018 to April 2021 were enrolled. Their length, weight, and head circumference were recorded at birth and at the corrected ages of 1, 3, 6, 12, 18, and 24 months. The preterm infants were grouped by perinatal factors. The growth curves of these infants were plotted and compared with the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) standard and World Health Organization (WHO) standard. RESULTS: The weight, length, and head circumference curves of each group of preterm infants grouped by various perinatal factors all rose rapidly within the corrected age of 6 months, but the growth rate slowed down after the corrected age of 6 months. Based on the actual age for the groups of preterm infants with different gestational ages (<28 weeks, 28-31 CONCLUSIONS The physical growth rate of preterm infants is faster within the corrected age of 6 months, and the growth rate slows down after the corrected age of 6 months. Preterm infants with a smaller gestational age need longer time to catch up in weight and head circumference. More attention should be paid to the physical growth of extremely preterm infants, extremely low birth weight infants, and small-for-gestational-age infants.

Medicinal plants have provided numerous medicinal active ingredients for thousands of years and these ingredients have been used in Chinese medicine (CM) and traditional pharmacologies worldwide. Recently, the exploitation and utilisation of medicinal plant resources has increased significantly. The results of the studies have led to the identification of many active components, such as steroidal alkaloids, saponins, terpenoids, and glycosides, in various medicinal plants with different evolutionary levels. Moreover, research on the chemical classification, molecular phylogeny, and pharmacological activity of medicinal plants is increasing in popularity. Pharmacophylogeny is an interdisciplinary topic that studies the correlation between plant phylogeny, chemical composition, and curative effects (pharmacological activity and the traditional curative effect) of medicinal plants. In addition, it provides the basic tools to enable research and development of CM resources. This literature review, based on the genetic relationship between phytogroup and species, highlights the formation process, research content, applications, and future directions of pharmacophylogeny.

By referring to the relevant ancient herbal literature， medical records and prescription books， the textual research of Violae Herba has been conducted to verify the name， origin， producing area， quality evaluation and processing method changes. The results showed that the name of Zihua Diding originated from its flower color and plant morphological characteristics. The primitive plant of Violae Herba is Viola genus of Violaceae， V. yedoensis， as stipulated in the 2020 edition of Chinese Pharmacopoeia， has been the mainstream in past dynasties of China. Violae Herba is mainly wild， and it is widely distributed throughout the country. Since modern times， the quality of Violae Herba is better with integrity， green color and yellow root. There are few records on the harvesting and processing methods of Violae Herba in ancient times， most of which are directly used after drying. It is suggested that the collection and processing methods of Violae Herba in the famous classical formulas can be implemented in accordance with the provisions of the 2020 edition of Chinese Pharmacopoeia.

Paeonia lactiflora is an important medicinal resource in China. It is of great significance for the protection and cultivation of P. lactiflora resources to find the suitable habitats. The study was based on the information of 98 distribution sites and the data of 20 current environmental factors of wild P. lactiflora in China. According to the correlation and importance of environmental factors, we selected the main environmental factors affecting the potential suitable habitats. Then, BCC-CSM2-MR model was employed to predict the distribution range and center change of potential suitable habitat of wild P. lactiflora in the climate scenarios of SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 during 2021-2100. The ensemble model combined with GBM, GLM, MaxEnt, and RF showed improved prediction accuracy, with TSS=0.85 and AUC=0.95. Among the 20 environmental factors, annual mean temperature, monthly mean diurnal range of temperature, temperature seasonality, mean temperature of the warmest quarter, precipitation of the wettest month, precipitation seasonality, precipitation of the driest quarter, and elevation were the main factors that affected the suitable habitat distribution of P. lactiflora. At present, the potential suitable habitats of wild P. lactiflora is mainly distributed in Inner Mongolia, Heilongjiang, Jilin, Liaoning, Hebei, Beijing, Shaanxi, Shanxi, Shandong, Gansu, Xinjiang, Tibet, and Ningxia, and concentrated in the northeastern Inner Mongolia, central Heilongjiang, and northern Jilin. Under future climate conditions, the highly sui-table area of wild P. lactiflora will shrink, and the potential suitable habitat will mainly be lost to different degrees. However, in the SSP5-8.5 scenario, the low suitable area of wild P. lactiflora will partially increase in the highlands and mountains in western China including Xinjiang, Tibet, and Qinghai during 2061-2100. The distribution center of wild P. lactiflora migrated first to the northeast and then to the southwest. The total suitable habitats were stable and kept in the high-latitude zones. The prediction of the potential geo-graphical distribution of P. lactiflora is of great significance to the habitat protection and standardized cultivation of this plant in the future.
