OBJECTIVE To observe the effects of Modified shaoyao gancao decoction on intestinal transit function, intestinal flora and the contents of metabolites [γ aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT)] in slow transit constipation (STC) rats. METHODS SD rats were randomly divided into blank group (10 rats) and modeling group (30 rats), with half male and half female. The STC model was established by intragastric administration of Compound diphenoxylate tablets in the modeling group. The successfully modeled rats were randomly divided into model group, Modified shaoyao gancao decoction group [56 g/(kg·d), calculated by crude drug] and positive control group [lactulose 2.09 g/(kg·d)], with 10 rats in each group. Each administration group was given relevant medicine intragastrically, the blank group and model group received an equivalent volume of normal saline, once a day, for 14 consecutive days. During the experiment, the general situation of rats was observed in each group. After the last medication, the body weight was measured, and the Bristol score was used to evaluate the fecal characteristics. The fecal moisture content, intestinal propulsion rate, and the contents of GABA and 5-HT in intestinal content were detected; the diversity of intestinal flora in intestinal contents was investigated, and the correlation between the contents of GABA, 5-HT and relative abundance of microbiota was analyzed. RESULTS Compared with the model group, general conditions such as small body shape, sparse and rough fur, and slow movement were all improved in Modified shaoyao gancao decoction body weight, Bristol score, fecal moisture content,intestinal propulsion rate, 5-HT content, Chao1 index and Shannon index were increased significantly, while GABA content and Simpson index were decreased significantly (P<0.05). The intestinal flora of rats in the Modified shaoyao gancao decoction group could be classified as the same as the blank group, but was far from the model group; the relative abundances of Desulfobacterota, Firmicutes and Bacteroidota in this group showed a tendency of pull back, but the differences were not statistically significant compared to model group (P>0.05). Desulfobacterota was an intergroup differential factor (P<0.05). The content of GABA was negatively correlated with the relative abundance of Bacteroidota, Cyanobacteria, Patescibacteria and Actinobacteriota (P<0.05). The content of 5-HT was positively correlated with the relative abundance of Campilobacterota (P<0.05). CONCLUSIONS Modified shaoyao gancao decoction can improve the fecal properties and intestinal motility of STC rats. Its mechanism may be related to improving intestinal flora and then affecting the contents of GABA and 5-HT in intestinal contents. In addition, the contents of GABA and 5-HT may be significantly correlated with the relative abundance of specific bacterial phyla such as Bacteroidota and Campilobacterota.

[Objective] To explore the effectiveness of applying the PDCA (Plan-Do-Check-Act) cycle to enhance the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients across multiple hospital campuses. [Methods] Clinical blood transfusion data from May to July 2022 were selected. Specific improvement measures were formulated based on the survey results, and the PDCA cycle management model was implemented from August 2022. The post-intervention phase spanned from August 2022 to October 2023. The Rh phenotype compatibility rate, the detection rate of Rh system antibodies, and the proportion of Rh system antibodies among unexpected antibodies were compared between the pre-intervention phase (May to July 2022) and the post-intervention phase. [Results] After the continuous improvement with the PDCA cycle, the compatibility rate for the five Rh blood group antigen phenotypes between donors and recipients from August to October 2023 reached 81.90%, significantly higher than the 70.54% recorded during the pre-intervention phase (May to July 2022, P<0.01), and displayed a quarterly upward trend (β=0.028, P<0.05). The detection rate of Rh blood group system antibodies (β=-9.839×10-5, P<0.05) and its proportion among all detected antibodies (β=-0.022, P<0.05) showed a quarterly decreasing trend, both demonstrating a negative correlation with the enhanced compatibility rate (r values of -0.981 and -0.911, respectively; P<0.05). [Conclusion] The implementation of targeted measures through the PDCA cycle can effectively increase the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients, reduce the occurrence of unexpected Rh blood group antibodies, thereby lowering the risk of transfusion and enhancing the quality and safety of medical care.

This article systematically analyzes the historical evolution of the name, medicinal parts, origin, harvesting, processing and other aspects of Houttuyniae Herba(HH) by referring to the medical books, prescription books and other documents of the past dynasties, combined with the research materials related to modern and contemporary times, in order to provide a basis for the development of famous classical formulas containing this herb. In ancient literature, HH was often referred to as "Ji" and "Jicai", the name of "Ji" was first recorded in Mingyi Bielu during the Han and Wei dynasties, and the name of Yuxingcao was first seen in Lyuchanyan Bencao during the southern Song dynasty and has continued to this day. The origin of HH used throughout history is consistent, all of which are the whole herb or aboveground parts of Houttuynia cordata in Saururaceae family. HH recorded throughout history has a wide range of production areas, mostly self-produced self-marketing. In ancient times, fresh HH was often used as medicine by pounding its juice without involving any processing steps. Both fresh and dried products can be used as medicine, the fresh products uses the whole plant, while the dried products uses the aboveground parts, which are cleaned, selected and processed before use. Fresh products are harvested regardless of season, while dried products are harvested in both summer and autumn, with summer as the best. In ancient times, there were no specific requirements for the quality of HH, while in modern times, "intact stems and leaves with a strong fishy smell" are preferred. In addition, the medicinal properties of HH have undergone significant changes from ancient to modern times. In the early period, it was believed that its medicinal property was slightly warm, until the 1977 edition of Chinese Pharmacopoeia officially changed it to slightly cold. Both ancient and modern literature states that HH can be used for the treatment of carbuncle and malignant sores, Lyuchanyan Bencao for the first time introduced HH fresh juice can relieve summer heat, since Diannan Bencao recorded that it can be used for lung carbuncle, and gradually developed into the first choice for the treatment of lung carbuncle. Based on the research results, it is suggested that fresh herb or dried aboveground parts of H. cordata are used as medicine when developing famous classical formulas.

This article systematically analyzes the historical evolution of the name, origin, quality evaluation, harvesting, processing and other aspects of Picrorhizae Rhizoma by referring to the medical books, prescription books, and other documents of the past dynasties, combined with relevant modern research materials, in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history, Huhuanglian has been used as its official name, and there are also aliases such as Gehu Luze, Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times, Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions, and also produced in China, mainly in Xizang. In ancient times, it was harvested and dried in early August of the lunar calendar, while in modern times, it is mostly harvested from July to September, with the best quality being those with thick and crispy rhizomes without impurities, and bitter taste. Throughout history, Picrorhizae Rhizoma was collected, washed, sliced, and dried before being used as a raw material for medicine, it has a bitter and cold taste, mainly used to treat bone steaming, hot flashes, infantile chancre fever, and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results, it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia, or the rhizomes of P. kurrooa, can be used in famous classical formulas containing this medicinal herb, which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements, the dried raw products are used as medicine.

ObjectiveTo study the effects of applying different microbial fertilizers on the growth and rhizosphere soil environment of Codonopsis pilosula and provide a theoretical basis for ecological cultivation of this medicinal plant. MethodsSeven groups were designed, including CK (no application of microbial fertilizer), T1 (Trichoderma longibrachiatum fertilizer), T2 (Bacillus subtilis fertilizer), T3 (Trichoderma viride fertilizer), T4 (compound microbial fertilizer), T5 (C. pilosula stems and leaves fermented with compound microbial fertilizer), and T6 (Scutellaria baicalensis stems and leaves fermented with T. viride fertilizer). The physiological indicators, yield, and quality of C. pilosula and the physicochemical properties, enzyme activities, and microbial diversity in the rhizosphere soil of different fertilizer treatments were measured. ResultsGroup T1 showed slight decreases in soluble protein content (SPC) and superoxide dismutase (SOD). Groups T2-T6 showed increases in physiological indicators such as proline (Pro), soluble solids content (SSC), SPC, catalase (CAT), and peroxidase (POD) and a decrease in malondialdehyde (MDA) in C. pilosula leaves. All the fertilizer treatments increased the yield of C. pilosula and the total polysaccharide content in the roots. T1, T2, T3, T4, and T5 increased the total flavonoid content in the roots. Meanwhile, T4 increased the total saponin content in the roots. All the fertilizer treatments reduced the pH and increased the electric conductivity (EC), soil organic matter (SOM), and alkaline nitrogen (AN) in the soil. T2 and T5 increased the available phosphorus (AP), and T3, T4, T5, and T6 increased the available potassium (AK) in the soil. All the fertilizer treatments increased the activities of urease, sucrase, and CAT in the soil. Except that T1 decreased the bacterial diversity in the soil, other fertilizer treatments significantly increased bacterial and fungal diversity in the soil. Different fertilizer treatments significantly affected the composition of bacterial and fungal communities in the soil. At the phylum level, the dominant bacterial phyla included Proteobacteria, Acidobacteriota, and Bacteroideta, and the dominant fungal phyla were Ascomycota, Mortierellomycota, and unclassified_fungi in the rhizosphere soil of C. pilosula after bacterial fertilizer treatment. At the genus level, unclassified Gemmatimonadaceae, Sphingomonas, and unclassified Vicinamibacteraceae were the dominant bacterial genera, while unidentified, unclassified Fungi, and unclassified Sordariomycetes were the dominant fungal genera in the rhizosphere soil. The results of redundancy analysis indicated that the main physicochemical factors affecting changes of microbial communities in the rhizosphere soil of C. pilosula were pH, EC, AK, AN, AP, and soil organic matter (SOM) in the soil. The correlation heatmap showed that Bryobacter had significantly positive correlations with EC, AK, and AN. There was a significantly negative correlation between Fusarium and SOM. In summary, applying an appropriate amount of microbial fertilizer can promote the growth and improve the rhizosphere soil environment of C. pilosula. ConclusionThe compound microbial fertilizer and the C. pilosula stems and leaves fermented with compound microbial fertilizer can improve the soil nutrients, growth, development, yield, and quality of C. pilosula, and thus they can be applied to the artificial cultivation of C. pilosula.

In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma, this article systematically analyzes the historical evolution of the name, origin, harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica, prescription books, medical books and modern literature. The research results showed that Baiji(白及) was the main name, some scholars took Baiji(白芨) as its main name, and there were many other names such as Baiji(白给), Baigen(白根), Baiji(白苙). The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata, and drying, large, white, solid, root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials, there were certain differences between their traits, and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed, with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn, and harvested in autumn was better. The processing and processing technology is relatively simple, and it was used fresh or powdered in past dynasties, while it is mainly sliced for raw use in modern times. Based on the results, it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas, and it should be uniformly written as Baiji(白及). And if the original formula indicates the requirement of processing, it should be operated according to the requirement, if the requirement of processing is not indicated, it can be used in raw form as medicine.

The aqueous two-phase system (ATPS) is an all-aqueous system fabricated from two immiscible aqueous phases. It is spontaneously assembled through physical liquid-liquid phase separation (LLPS) and can create suitable templates like the multicompartment of the intracellular environment. Delicate structures containing multiple compartments make it possible to endow materials with advanced functions. Due to the properties of ATPSs, ATPS-based drug delivery systems exhibit excellent biocompatibility, extraordinary loading efficiency, and intelligently controlled content release, which are particularly advantageous for delivering drugs in vivo. Therefore, we will systematically review and evaluate ATPSs as an ideal drug delivery system. Based on the basic mechanisms and influencing factors in forming ATPSs, the transformation of ATPSs into valuable biomaterials is described. Afterward, we concentrate on the most recent cutting-edge research on ATPS-based delivery systems. Finally, the potential for further collaborations between ATPS-based drug-carrying biomaterials and disease diagnosis and treatment is also explored.
