Zhishi Shaoyaosan is the 34^th prescription in the Catalogue of Ancient Classic Formulas （Second Batch） published by the National Administration of Traditional Chinese Medicine in 2023. It is widely used in clinical practice and has a definite curative effect. However， there is currently a lack of its ancient literature analysis and textual research， and there is no corresponding Chinese patent medicine preparation. By consulting and combing the relevant ancient books of traditional Chinese medicine， this paper analyzes and conducts textual research of the origin， composition， measurement， administration， and efficacy of Zhishi Shaoyaosan. The results show that Zhishi Shaoyaosan is derived from Essentials from the Golden Cabinet written by Zhang Zhongjing in the Eastern Han Dynasty. It is mainly recorded in the name of Zhishi Shaoyaosan in the literature of the past dynasties. The prescription is composed of Aurantii Fructus Immaturus and Paeoniae Radix Alba. The processing method is stir-frying Aurantii Fructus Immaturus to scorch and using raw Paeoniae Radix Alba. The dose of the prescription recorded in the ancient books is mainly an equal amount of Aurantii Fructus Immaturus and Paeoniae Radix Alba in one square-cun spoon， taken three times a day， which is converted into a modern dose of 1.5 g each time （0.75 g Aurantii Fructus Immaturus and 0.75 g Paeoniae Radix Alba each time）. The components of the prescription are ground into powder and taken with barley porridge， three times a day. The efficacy is to break stagnated Qi， harmonize blood， and relieve restlessness and pain. It is mainly used to treat postpartum abdominal pain， acute pelvic inflammatory disease， acute cholecystitis and intestinal diseases， stroke sequelae， and other diseases. This study combs and analyzes the ancient literature recording Zhishi Shaoyaosan and clarifies the key information of the prescription， which provides a basis for promoting the research and development of its patent medicine.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry（UPLC-Q-Orbitrap-MS）， to identify the in vivo and in vitro chemical components of total phenolic acids in Gei Herba（TPAGH）， and to clarify the pharmacological effects and potential mechanisms of the effective part in promoting acute wound healing and inhibiting scar formation. MethodsUPLC-Q-Orbitrap-MS was used to identify the chemical components of TPAGH and ingredients absorbed in vivo after topical administration. A total of 120 ICR mice were randomly divided into the model group， recombinant human epidermal growth factor（rhEGF） group（4 mg·kg^-1）， and low， medium， and high dose groups of TPAGH（3.5， 7， 14 mg·kg^-1）， with 24 mice in each group. A full-thickness skin excision model was constructed， and each administration group was coated with the drug at the wound site， and the model group was treated with an equal volume of normal saline， the treatment was continued for 30 days， during which 8 mice from each group were sacrificed on days 6， 12， and 30. The healing of the wounds in the mice was observed， and histopathological changes in the skin tissues were dynamically observed by hematoxylin-eosin（HE）， Masson， and Sirius red staining， and enzyme-linked immunosorbent assay（ELISA） was used to dynamically measure the contents of interleukin-6（IL-6）， tumor necrosis factor-α（TNF-α）， vascular endothelial growth factor A（VEGFA）， matrix metalloproteinase（MMP）-3 and MMP-9 in skin tissues. Network pharmacology was used to predict the targets related to the promotion of acute wound healing and the inhibition of scar formation by TPAGH， and molecular docking of key components and targets was performed. Gene Ontology（GO） biological process analysis and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analysis were carried out for the related targets， so as to construct a network diagram of herbal material-compound-target-pathway-pharmacological effect-disease for further exploring its potential mechanisms. ResultsA total of 146 compounds were identified in TPAGH， including 28 phenylpropanoids， 31 tannins， 23 triterpenes， 49 flavonoids， and 15 others， and 16 prototype components were found in the serum of mice. Pharmacodynamic results showed that， compared with the model group， the TPAGH groups showed a significant increase in relative wound healing rate and relative scar inhibition rate（P<0.05）， and the number of new capillaries， number of fibroblasts， number of new skin appendages， epidermal regeneration rate， collagen deposition ratio， and Ⅲ/Ⅰ collagen ratio in the tissue were significantly improved（P<0.05， 0.01）， the levels of IL-6， TNF-α， MMP-3 and MMP-9 in the skin tissues were reduced to different degrees， while the level of VEGFA was increased. Network pharmacology analysis screened 10 core targets， including tumor protein 53（TP53）， sarcoma receptor coactivator（SRC）， protein kinase B（Akt）1， signal transducer and activator of transcription 3（STAT3）， epidermal growth factor receptor（EGFR） and so on， participating in 75 signaling pathways such as advanced glycation end-products（AGE）-receptor for AGE（AGE/RAGE） signaling pathway， phosphatidylinositol 3-kinase（PI3K）/Akt signaling pathway， mitogen-activated protein kinase（MAPK） signaling pathway. Molecular docking confirmed that the key components genistein， geraniin， and casuariin had good binding ability to TP53， SRC， Akt1， STAT3 and EGFR. ConclusionThis study comprehensively reflects the chemical composition of TPAGH and the absorbed components after topical administration through UPLC-Q-Orbitrap-MS. TPAGH significantly regulates key indicators of skin healing and tissue reconstruction， thereby clarifying its role in promoting acute wound healing and inhibiting scar formation. By combining in vitro and in vivo component identification with network pharmacology， the study explores how key components may bind to targets such as TP53， Akt1 and EGFR， exerting therapeutic effects through related pathways such as immune inflammation and vascular regeneration.

ObjectiveTo investigate the mechanism of action of Huangqi Guizhi Wuwutang （HGWT） against cerebral ischemia-reperfusion injury （CIRI） based on bioinformatics and experimental validation. MethodsBiological informatics methods were used to screen for active components of HGWT and their targets. The GEO database was utilized to obtain CIRI-related differentially expressed genes （DEGs）， and platforms such as GeneCards were used to identify disease targets. Venn diagram analysis was conducted to identify overlapping targets， followed by protein-protein interaction （PPI）， gene ontology （GO）， and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis， as well as immune infiltration and immune cell differential analysis. Core genes （Hub genes） were screened using LASSO regression and ROC curves， and molecular docking was used to validate the binding efficiency between the active components of the drug and the core targets. A rat CIRI model was established， with rats randomly divided into five groups （n=10）： Sham surgery group （Sham）， model group （MG）， and low-dose （LD，5.3 g·kg^-1）， medium-dose （MD，10.6 g·kg^-1）， and high-dose （HD，21.2 g·kg^-1） HGWT groups. From 3 days before modeling to 7 days after surgery， oral administration was performed daily： Sham and MG groups received physiological saline， while each drug group received the corresponding dose of HGWT. Hematoxylin-eosin （HE） staining， Nissl staining， and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL staining） were used to assess the repair effects of HGWT on neural damage. Western blot analysis was used to detect B-cell lymphoma-2 protein （Bcl-2）， Bcl-2-associated X protein （Bax）， signal transducer and activator of transcription 3 （STAT3）， phosphorylated STAT3 ［p-STAT3 （Tyr705）］， protein kinase B1 （Akt1）， and phosphorylated Akt1 ［p-Akt1 （Ser473）］， among other target proteins. ResultsAfter screening， 56 common target points of DEGs-disease-drug were obtained. GO and KEGG analyses indicated that HGWT primarily functions in pathways such as apoptosis， oxidative stress， and inflammatory responses. Immune infiltration analysis revealed a significant association between HGWT's anti-CIRI activity and immune cells such as Th17 cells and myeloid-derived suppressor cells （MDSCs） （P0.01）. LASSO-ROC analysis identified Akt1， Caspase-3， glycogen synthase kinase-3β （GSK-3β）， and STAT3 as core genes. Molecular docking confirmed that Hub genes exhibit significant binding affinity with the active components of HGWT （binding energy ≤ -5 kJ·mol^-1）（1 cal≈4.186 J）. Animal experiment results showed that compared with the sham group， the MG group exhibited significant neuronal necrosis， nuclear condensation， and vacuolar degeneration in rat brains， with a significant decrease in Nissl body density （P0.01） and increased neuronal apoptosis in rat brains as indicated by TUNEL staining （P0.01）. Compared with the MG， the LD， MD， and HD groups showed reduced neuronal necrosis， nuclear condensation， and vacuolar degeneration in rat brain neurons， increased Nissl body density， and reduced apoptosis （P0.01）， with significant differences among the drug groups （P0.01）. Western blot results showed that compared with the sham group， the MG group had reduced Bcl-2 and p-Akt1 （P0.01） and increased Bax and p-STAT3 （P0.01）. Compared with the MG group， the drug groups showed increased Bcl-2 and p-Akt1 （P0.01） and decreased Bax and p-STAT3 （P0.01）. There were no significant changes in total Akt1 and STAT3 protein levels among the groups. ConclusionBased on network pharmacology and experimental verification， HGWT may exert its neuroprotective effects by regulating the phosphorylation levels of Akt1 and STAT3， thereby alleviating cell apoptosis， inflammatory responses， and oxidative stress in rat brain tissue following CIRI. This provides theoretical support for the clinical treatment of CIRI.

ObjectiveThis study aims to investigate the inhibitory effect of Wutoutang on pannus formation in adjuvant-induced arthritis （AIA） rats with wind-cold-dampness Bi syndrome and its potential mechanism. MethodA total of 40 male SD specific pathogen-free （SPF） rats were selected and divided into blank group， wind-cold-dampness Bi syndrome group ［Complete Freund's Adjuvant （CFA）， 200 μg］， Wutoutang group （15 g·kg^-1·d^-1）， and indometacin group （10 mg·kg^-1） according to random number table method. Except for the blank group， the other groups were given wind-cold-dampness stimulation before the CFA injection. After the rats were administered for 30 days， the basic conditions， onset time， arthritis index score， and foot swelling volume of AIA rats with wind-cold-dampness Bi syndrome were observed. Finally， peripheral arterial blood， ankle joint， and synovial tissue were taken. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum hypoxia-inducible factor-1α （HIF-1α）， vascular endothelial growth factor A （VEGFA） protein content， and rheumatism， including anti-O （ASO）， C-reactive protein （CRP）， and rheumatoid factor （RF）. Hematoxylin-eosin （HE） staining revealed the changes in joint histomorphology. Immunohistochemistry was used to detect the expression of HIF-1α and VEGFA， two important proteins in the ankle pathway. Quantitative real-time polymerase chain reaction （Real-time PCR） was used to reveal mRNA levels of HIF-1α， VEGFA， angiopoietin-1 （Ang-1）， and angiopoietin-2 （Ang-2） in rat synovial tissue. ResultThe foot swelling volume and arthritis score of AIA rats with wind-cold-dampness Bi syndrome were substantially higher （P<0.01） compared with the blank group. Serum CRP， RF， and ASO levels were considerably elevated （P<0.01）. HE staining showed obvious hyperplasia of ankle synovium and synovial inflammation， angiogenesis and pannus formation， and aggravated bone destruction， indicating successful modeling. After the intervention of Wutoutang， the onset time was delayed （P<0.01）. Foot swelling volume and arthritis score were decreased （P<0.01）. Serum CRP， RF， and ASO levels were significantly decreased （P<0.01）. The inflammatory hyperplasia of synovial tissue， angiogenesis and pannus formation， and bone destruction were alleviated. The mRNA levels of HIF-1α， VEGFA， Ang-1， and Ang-2 in the synovial membrane were significantly decreased （P<0.05， P<0.01）. The expressions of HIF-1α and VEGFA in serum and ankle joints were decreased （P<0.01）. In the indomethacin group， the onset time of the disease was delayed （P<0.01）. Foot swelling volume and arthritis score were decreased （P<0.01）. Serum CRP， RF， and ASO levels were significantly decreased （P<0.01）. HIF-1α/VEGFA/Ang signaling pathway was activated， and pathological tissue injury was improved. ConclusionWutoutang can delay the onset time of AIA rats with wind-cold-dampness Bi syndrome， reduce foot swelling volume， arthritis score， rheumatic activity， and improve joint histopathology. It can inhibit pannus formation， and its mechanism may be related to down-regulating the expression of the HIF-1α/VEGFA/Ang pathway.

Objective To study the pharmacokinetic characteristics of lamotrigine tablets in Chinese healthy subjects under fasting and fed conditions,and to evaluate the bioequivalence and safety profiles between the domestic test preparation and the original reference preparation.Methods Twenty-four Chinese healthy male and female subjects were enrolled under fasting and fed conditions,18 male and 6 female subjects under fasting conditions,17 male and 7 female subjects under fed conditions.A random,open,single-dose,two preparations,two sequences and double-crossover design was used.Plasma samples were collected over a 72-hour period after give the test or reference preparations 50 mg under fasting and fed conditions.The concentration of lamotrigine in plasma was detected by liquid chromatography-tandem mass spectrometry,and the main pharmacokinetic parameters were calculated to evaluate the bioequivalence by WinNonLin 8.1 program.Results The main pharmacokinetic parameters of single-dose the tested and reference preparations were as follows:The fasting condition Cmax were(910.93±248.02)and(855.87±214.36)ng·mL-1;tmax were 0.50(0.25,4.00)and 1.00(0.25,3.50)h;t1/2 were(36.1±9.2)and(36.0±8.2)h;AUC0_72h were(27 402.40±4 752.00)and(26 933.90±4 085.80)h·ng·mL-1.The fed condition Cmax were(701.62±120.67)and(718.95±94.81)ng·mL-1;tmax were 4.00(1.00,5.00)and 4.00(0.50,5.00)h;t1/2 were(44.2±12.4)and(44.0±12.0)h;AUC0-72h were(30 253.20±7 018.00)and(30 324.60±6 147.70)h·ng·mL-1.The 90％confidence intervals of the geometric mean ratios of Cmax and AUC0-72 hfor the test preparation and reference preparation were all between 80.00％and 125.00％under fasting and fed conditions.Conclusion Two kinds of lamotrigine tablets are bioequivalent,and have similar safety in Chinese healthy male and female subjects under fasting and fed conditions.

Objective To study the distribution and significance of CD1a and CD83 positive dendritic cells(DCs)in lung tissue of chronic obstructive pulmonary disease(COPD)mice.Methods Twenty C57BL/6 mice were randomly divided into the air control group and the smoked COPD group(n=10 for each group).COPD mouse model was established using cigarette smoking method.Mice were executed within 24 h after the last cigarette smoking,and right lower lung was collected.Body mass changes and lung histopathological changes of mice were observed in two groups.Mean linear intercept(MLI)was measured,and expression levels of CD1a+and CD83+DCs in lung tissue were detected by immunohistochemistry.Results The body mass of mice at 7,14,21 and 28 d after modeling was lower in the smoked COPD group than that in the air control group(P＜0.05).HE staining showed that the normal alveolar structure of lung tissue of mice in the smoked group was disrupted,with multiple alveoli fused with each other to form a larger alveolar lumen,a large number of inflammatory cells infiltrated in alveolar intervals,and walls of the alveoli were thickened.COPD modeling was successful.Compared with the air control group,MLI values(μm)increased in the smoked COPD group(28.30±3.47 vs.50.40±3.60),and the number of CD1a+DCs(per field of view)in lung tissue increased(9.58±2.18 vs.17.08±3.67),while the number of CD83+DCs(per field of view)decreased(19.78±4.95 vs.8.02±3.30)(all P＜0.05).Conclusion The number of CD1a+DCs in lung tissue is increased and the number of CD83+DCs in lung tissue is decreased in the smoked COPD group of mice,and cigarette smoking may have impaired DC maturation.

Objective To observe the effect of electroacupuncture(EA)on the expression of NKCC1,KCC2 and activation of microglia in spinal dorsal horn of paclitaxel(PTX)-induced neuropathic pain rats and its possible mechanism.Methods Male SD rats were randomly divided into the vehicle group(vehicle),the PTX group,the PTX+EA group and the PTX+sham EA group,with 12 rats in each group.The rat model of PTX-induced neuropathic pain was established by intraperitoneal injection of PTX.After modeling,EA was applied to"Zusanli"and"Yanglingquan"for 7 days in the PTX+EA group.Paw withdrawal threshold and paw withdrawal latency were tested at 2 days before and 1,3,5,7,14 and 21 days after PTX injection.Immunofluorescence and Western blot assay were used to detect expression levels of sodium-potassium-chloride cotransporter 1(NKCC1),potassium-chloride cotransporters 2(KCC2)and microglia markers-ionized calcium binding adapter molecule 1(Iba1)in spinal dorsal horn.Results Compared with the vehicle group,mechanical and thermal hyperalgesia of both hind feet were found in the PTX group,and the expression of NKCC1 and the number of activated microglia in dorsal horn tissue of spinal cord were increased.Compared with the PTX group,mechanical and thermal hyperalgesia were significantly improved in the PTX+EA group at day 14 and 21,and the expression levels of NKCC1 and Iba1 in dorsal horn tissue of spinal cord were decreased.There was no significant difference in KCC2 expression between the four groups.Conclusion Electroacupuncture can effectively relieve paclitaxol-induced neuropathic pain,which may be related to the inhibition of NKCC1 expression and microglia activation in spinal dorsal horn of rats.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To compare the clinical value of digital breast tomosynthesis (DBT) localization and stereotactic positioning biopsy of breast lesions.Methods:This study was a cross-sectional study. Totally of 250 patients who underwent breast biopsy at Shenzhen People′s Hospital, Luohu District People′s Hospital and Peking University Shenzhen Hospital between August 2021 to October 2023 was analyzed retrospectively, including 136 cases of DBT-guided biopsy (DBT-guided group) and 114 cases of stereotactic-guided biopsy (stereotactic-guided group). The stereotactic-guided biopsy methods included core needle biopsy (CNB) and wire positioning. The DBT-guided biopsy methods included CNB, wire positioning and vacuum-assisted breast biopsy (VABB). The χ2 test or Mann-Whitney U test was used to compare the puncture success rate, operation time, localization time, puncture time, number of first valid localization phases obtained, number of exposures, and complications of different biopsy methods between 2 groups. Results:In the wire positioning biopy, the puncture success rate was 100% (33/33) in DBT-guided group and 96% (48/50) in the stereotactic-guided group, with no statistically significant difference between the two groups ( P=0.515). Compared to the stereotactic-guided group, the operation time and localization time were shorter, and the number of first valid localization phases obtained, number of exposures were fewer in the DBT-guided group( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.871). In CNB, both the DBT-guided group and the stereotactic-guided group had higher puncture success rates, with no statistically significant difference ( P=0.080). Compared to the stereotactic-guided group, the operation time, localization time and puncture time were shorter, and the number of first valid localization phases obtained, number of exposures were lower in the DBT-guided group, and the difference between the two groups were statistically significant ( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.627). Twenty-one cases received DBT-guided VABB, with an operation time of (19.90±3.38) min, a localization time of 6.00 (6.00, 7.00) min, a puncture time of (13.42±3.28) min, the number of first effective localization phases obtained was 1.00 (1.00, 1.00) time, the number of exposures was 4.00 (3.50, 5.00) times, and one case experienced severe pain after puncture. Conclusion:Compared with stereotactic-guided biopsy, DBT-guided biopsy can reduce operation time and exposure times, and can target more types of breast lesions, with higher clinical application value.

Objective:To explore the prevalence, clinical features, genetic characteristics and prognosis of Citrin deficiency in Henan province of China.Methods:A total of 986 565 neonates screened by tandem mass spectrometry at the Third Affiliated Hospital of Zhengzhou University from January 2013 to December 2021 were retrospectively analyzed. Analysis of SLC25A13 gene variants and parental verification were carried out for neonates suspected for Citrin deficiency by next-generation sequencing. The clinical, biochemical and genetic characteristics of Citrin deficiency patients were integrated to guide the diet treatment and follow up the growth and development. Paired- t test was used to compare the amino acid levels in the peripheral blood samples before and after the treatment. Results:Nine cases of Citrin deficiency were diagnosed among the 986 565 neonates. Specific elevation of citrulline was observed in all of the 9 cases. Six variants were detected by genetic sequencing, among which c. 852_855delTATG, c. 615+ 5G>A, c. 550C>T and IVS16ins3kb were known pathogenic variants, whilst c. 1111_1112delAT and c. 837T>A were unreported previously. The detection rate for c. 852_855delTATG was the highest (61.6%, 11/18), followed by IVS16ins3kb (16.7%, 3/18). The clinical symptoms of all patients were relieved after the treatment, and the blood amino acid profile and biochemical parameters were significantly improved by gradually falling within the normal range. By June 2022, all patients had shown a good prognosis.Conclusion:The prevalence of Citrin deficiency among neonates from Henan Province by tandem mass spectrometry is 1/109 618, and the carrier rate for the pathogenic variants of the SLC25A13 gene was 1/166. The c. 852_855delTATG may be a hot spot variant among the patients. Discovery of the novel variants has enriched the mutational spectrum of the SLC25A13 gene. Above results have provided a basis for the early diagnosis, treatment, prognosis and genetic counseling for the affected families.
