The literature on the characteristics, commodity grade specifications and chemical composition of Angelicae Sinensis Radix was reviewed. It was found that the main factors affecting the changes of traits and chemical composition of Angelicae Sinensis Radix included origin, altitude, climate, soil, cultivation methods, processing and processing methods and storage methods. Among them, the volatile oil types and ferulic acid content of Angelicae Sinensis Radix produced in Minxian County of Gansu Province were better than those in some non-authentic producing areas, but some component differences remained to be verified; direct seeding and film mulching cultivation could improve the yield, volatile oil and polysaccharide content of Angelicae Sinensis Radix; continuous cropping may lead to rhizosphere soil problems of Angelicae Sinensis Radix, and rotation or intercropping could be considered; drying in the shade and smoking drying could retain the oil and aroma of Angelicae Sinensis Radix; wine stir-frying method could increase the content of Z-ligustilide, but stir-frying carbon may reduce the content of ferulic acid; high temperature and high humidity storage may affect the content of ligustilide. In the future, the quality evaluation system of Angelicae Sinensis Radix should be strengthened and improved, genuine research should be strengthened, and scientific field management methods and appropriate harvesting and processing methods should be established, so as to ensure the good clinical efficacy and stable and controllable quality of Angelicae Sinensis Radix.

Objective To explore the efficacy of the self-formulated Zhuzhang Formula in trea-ting the spleen deficiency with dysfunction of transportation syndrome of idiopathic short stature(ISS)and its effects on the growth rate,disease-related indicators,and bone metabolism indicators in affect-ed children.Methods A total of 80 children with ISS were enrolled as study subjects.They were randomly assigned to control group and observation group using random number table method,with 40 cases in each group.The control group received conventional western medicine treatment,while the observation group was administered self-formulated Zhuzhang Formula in addition to the treatment of the control group.Comparisons were made between the two groups in terms of clinical efficacy,TCM syndrome scores,growth parameters(monthly average height increment,annual growth rate),levels of disease-related indicators[serum insulin-like growth factor-1(IGF-1),bone morphogenetic pro-tein-2(BMP-2),insulin-like growth factor binding protein-3(IGFBP-3)],levels of bone metabo-lism indicators[bone alkaline phosphatase(BAP),type Ⅰ procollagen N-terminal propeptide(PⅠNP),type Ⅰ collagen cross-linked C-terminal telopeptide(β-CTX)],and the incidence of adverse reac-tions.Results The overall effective rate in the observation group was 97.50％,which was significantly higher than the 80.00％ in the control group(P＜0.05).After 3 and 6 months of intervention,the scores for symptoms such as short stature,sallow complexion,loss of appetite,weak voice and shortness of breath,limb weakness,and loose stools,as well as the total TCM syndrome scores,were lower in the observation group than those in the control group,with statistically significant differences(P＜0.05).After 6 months of intervention,the monthly average height increment and annual growth rate were higher in the observation group than those in the control group,and the differences were statistically significant(P＜0.05).After 3 and 6 months of intervention,the levels of IGF-1,BMP-2,IGFBP-3,BAP,and PⅠNP were higher in the observation group than those in the control group,while the level of β-CTX was lower,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion The self-formulated Zhuchang Formula demon-strates remarkable efficacy in treating the spleen deficiency with dysfunction of transportation syndrome of ISS.It can alleviate clinical symptoms by regulating the levels of IGF-1,BMP-2,IGFBP-3,and bone metabolism indicators,thereby promoting the growth and development of affected children,and exhibits high safety.

Purpose To explore the clinicopathological features of cholangitis lenta.Methods The clinical data of 12 patients with cholangitis Lenta were collected,HE staining,his-tochemical staining and immunohistochemistry were used to de-tect the clinicopathological changes in 12 cases of cholangitis lenta,and the relevant literature was reviewed.Results All the 12 patients with cholangitis Lenta had acute history and ab-normal liver function,9 cases(75.0％)had abnormal white blood cell count,11 cases(91.7％)had abdominal infection,8 cases(66.7％)had systemic inflammatory response syndrome(SIRS)and 8 cases(66.7％)were diagnosed as sepsis.The common pathological manifestations included spotty necrosis(100％),piecemeal necrosis(100％),confluent necrosis(75.0％),bridging necrosis(66.7％),hepatocyte and capil-lary cholestasis(75.0％),and mild edema in portal area(33.3％).12 cases showed proliferation of bile ductules around the portal area,inspissated bile in dilated bile ductules and no cholestasis in interlobular bile ducts.12 cases had the basis of primary liver disease.2 patients(16.7％)died after being transferred to another hospital for treatment,and 10 patients(83.3％)survived,which lasted for 7 to 55 months.Conclu-sion Cholangitis Lenta shows unique clinical manifestations and morphological features,it is often accompanied by underly-ing diseases.The pathological manifestation of cholangitis Lenta in liver biopsy suggests that patients may have sepsis and/or ab-dominal infection,and therefore its diagnosis should be com-bined with clinical features,laboratory examination and imaging manifestations.

Objective To investigate the effects of linoleic acid(LA)on the diversity and structure of intestinal flora in mice.Methods Twelve SPF grade male C57BL/6J mice at 7 weeks were randomly divided into control group(CTRL group)and linoleic acid group(LA group).One day before the linoleic acid diet was supplemented,the normal food was removed from the LA group and the mice in the LA group were fasted for one night,so that the LA diet was more acceptable to the mice in the LA group,and LA was given on the day of the experiment recording,and the feed was updated at any time to ensure that the mice could eat freely until the end of modeling.After 12 weeks of modeling,mouse feces were collected,and mixed samples were collected for every two mice feces,and then 16sRNA high-throughput sequencing was performed to analyze intestinal flora structure,Alpha and Beta diversity.Results 16sRNA high-throughput sequencing showed that LA intervention damaged the richness and diversity of intestinal flora.The results of principal component analysis showed that the composition of flora in CTRL group was different from that in LA group.At gate level,the relative abundance of Actinobacteria in LA group increased(P＜0.01).At the genus level,the relative abundance of L.Duchennei in the LA group decreased(P＜0.05),but the relative abundance of Bifidobacterium,Faecalibaculum and Erysipelotrichaceae in the LA group increased(all P＜0.01).Conclusion LA intervention could reduce the richness and diversity of intestinal flora in mice,and adjust the structure of intestinal flora.There were significant differences between beneficial bacteria and pathogenic bacte-ria in intestinal flora after LA intervention,which provided certain basis for the treatment of bioactive compounds of linoleic acid and the therapeutic adjustment of intestinal microorganisms as targets.

Objective To analyze the effects of massage therapy on the inflammatory state and lung function of pediatric refractory Mycoplasma pneumonia (RMPP). Methods A total of 320 children with RMPP treated in Hebei Seventh People′s Hospital from September 2022 to August 2023 were selected in the study. According to different treatment methods, they were divided into two groups, with 160 cases in each group. The western medicine group was given conventional anti-inflammatory and other symptomatic treatment, while the massage group was given dialectical massage treatment based on the western medicine group. The clinical efficacy, duration of disappearance of clinical symptoms, pulmonary function indexes, serum inflammatory factors, immune function indexes and total incidence of adverse reactions were compared between the two groups. Results The total effective rate of massage group was higher than that of control group (P < 0.05). The disappearance time of fever, cough, sputum and lung moist rales in observation group was shorter than that in control group (P < 0.05). After treatment, the peak expiratory flow (PEF), maximum mid-expiratory flow (MMEF) and forced vital capacity (FVC) in the massage group were higher than those in the control group (P < 0.05). The levels of serum C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the massage group were lower than those in the control group after treatment (P < 0.05). After treatment, CD3⁺, CD4⁺, CD4⁺/CD8⁺ in the massage group were higher than those in the control group (P < 0.05), and CD8⁺ was lower than that in the control group (P < 0.05). There was nosignificant difference in the total incidence of adverse reactions between the massage group and the western medicine group (P>0.05). Conclusion Massage based on syndrome differentiation combined with western medicine can effectively relieve fever, cough and other symptoms of RMPP children, reduce inflammatory response, improve lung function and immune function, and has less adverse reactions.

The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.

OBJECTIVE: To explore the therapeutic mechanism of Liushen Wan (LSW) against colitis-associated colorectal cancer (CAC) by network pharmacology. METHODS: TCMSP, BATMAN-TCM, CNKI, PubMed, Genecards, OMIM, and TTD databases were used to obtain the related targets of LSW and CAC. The common targets of LSW and CAC were obtained using Venny online website. The PPI network was constructed using Cytoscape 3.8.2 to screen the core targets of LSW in the treatment of CAC. GO and KEGG enrichment analysis were conducted using DAVID database. The therapeutic effect of LSW on CAC was evaluated in a C57BL/6J mouse model of AOM/DSS-induced CAC by observing the changes in body weight, disease activity index, colon length, and size and number of the tumor. HE staining and RT-qPCR were used to analyze the effect of LSW on inflammatory mediators. Immunohistochemistry and TUNEL staining were used to evaluate the effect of LSW on the proliferation and apoptosis of AOM/DSS-treated colon tumor cells. Immunohistochemistry and Western blotting were used to detect the effects of LSW on the expression of TLR4 proteins in CAC mice. RESULTS: Network pharmacology analysis identified 69 common targets of LSW and CAC, and 33 hub targets were screened in the PPI network. KEGG pathway enrichment analysis suggested that the effect of LSW on CAC was mediated by the Toll-like receptor signaling pathway. In the mouse model of AOM/DSS-induced CAC, LSW significantly inhibited colitis-associated tumorigenesis, reduced tumor number and tumor load (P < 0.05), obviously improved histopathological changes in the colon, downregulated the mRNA levels of proinflammatory cytokines, and inhibited the proliferation (P < 0.01) and promoted apoptosis of colon tumor cells (P < 0.001). LSW also significantly decreased TLR4 protein expression in the colon tissue (P < 0.05). CONCLUSION LSW can inhibit CAC in mice possibly by regulating the expression of TLR4 to reduce intestinal inflammation, inhibit colon tumor cell proliferation and promote their apoptosis.

Type 2 diabetes mellitus （T2DM） is a chronic metabolic disease characterized by insulin resistance， hyperinsulinemia， and disturbance of glucose and lipid metabolism， with elevated blood glucose as the main clinical manifestation. Due to its complex etiology and pathogenesis， there is no effective treatment， which critically threatens human health and places a heavy burden on society and families. Saponins are a class of glycosides with complex structures that have the advantage of a wide range of sources， elevated safety， and low adverse effects. As an essential active ingredient in Chinese medicine， Chinese medicine saponins have a variety of biological activities such as hypoglycemia， hypoglycaemia， anti-inflammation， antioxidation， anti-tumor， and immune modulation. In recent years， numerous studies have shown that Chinese medicine saponins are effective in preventing and treating T2DM. Although there have been numerous studies on the hypoglycemic effects and mechanisms of Chinese medicine saponins， there has been no systematic review of the mechanisms of Chinese medicine saponins in the treatment of T2DM. Therefore， to provide a theoretical basis for an in-depth study of the hypoglycemic effects of Chinese medicine saponins and a scientific basis for the development and clinical application of drugs， this paper systematically summarized the hypoglycemic mechanisms of Chinese medicine saponins， such as improving islet β-cell function， improving insulin resistance， inhibiting glycosidase activity， reducing the inflammatory response， anti-oxidative stress， and regulating intestinal flora， and analyzed the current research problems and development trends.

ObjectiveTo investigate the effect of Loulianwan on the gut microbiota of db/db mice with type 2 diabetes mellitus （T2DM）. MethodMale db/m+ mice aged 4-5 weeks were assigned to the normal group， and male db/db model mice of the same age were randomly divided into model group， metformin group （0.25 g·kg^-1·d^-1）， and Loulianwan group （13 g·kg^-1·d^-1）， with six mice in each group. Drug intervention lasted five weeks. The body weight， water intake， and fasting blood glucose （FBG） of the mice were recorded every week. After five weeks， the FBG， liver triglyceride （TG）， liver total cholesterol （TC）， glycated serum protein （GSP）， and fasting serum insulin （FINS） were detected， and the insulin resistance index （HOMA-IR） was calculated. The feces in the mouse intestines were collected， and the 16S rRNA sequencing technology was used to detect the structural changes in the fecal gut microbiota of mice in each group. ResultCompared with the normal group， the model group showed increased body weight， water intake， FBG， liver TG， liver TC， GSP， FINS， and HOMA-IR （P<0.01）. Compared with the model group， the Loulianwan group showed reduced water intake， FBG， liver TG， liver TC， GSP， FINS， and HOMA-IR （P<0.01）. The gut microbiota in the Loulian Lills group changed from phylum to genus level. The relative abundance of beneficial bacteria increased and the relative abundance of harmful bacteria decreased. Among them， the abundance of Akkermansia muciniphila， Blautia， Ruminococcus， and Parabacteroides increased （P<0.01）. ConclusionLoulianwan can significantly improve glucose and lipid metabolism in db/db mice with T2DM， and its mechanism may be related to the increase in the abundance of Akkermansia muciniphila， Blautia， Ruminococcus， and Parabacteroides in the intestine.
