The study focuses on the concept of multifunctional traditional Chinese medicine (TCM) formulas and aims to evaluate the efficacy of the classical formula Xiaoyao San (逍遥散). Study employs the integrated evidence chain (Eff-iEC) method to organize, integrate, and evaluate its therapeutic efficacy in treating different diseases with the same therapy, and to investigate the feasibility of using Eff-iEC to evaluate the multifunctionality of TCM formulas. The evaluation covered Xiaoyao San's therapeutic effects on depression, premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Concurrently, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system was used for evaluation, and authoritative medical documents were incorporated to corroborate the recognition of Xiaoyao San within the medical community. Depression and menopausal syndrome received higher ratings than other conditions in the Eff-iEC, GRADE, and Medical Community Recognition assessments. The Eff-iEC evidence grade for Xiaoyao San was rated as "High" or above for chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Premenstrual syndrome received a "Moderate ⁺" rating. The GRADE evidence level was "Low-〇〇⨁⨁" for depression, premenstrual syndrome, and chronic hepatitis; "Moderate-〇⨁⨁⨁" for dyspepsia and menopausal syndrome; and "Very Low-〇〇〇⨁" for irritable bowel syndrome. Depression and menopausal syndrome had the highest inclusion frequency, appearing in all 4 categories. Premenstrual syndrome, chronic hepatitis, and dyspepsia are not recommended in Western medical guidelines, but they are included in TCM guidelines, the China National Basic Medical Insurance Drug List, and the China National Essential Drug List. Irritable bowel syndrome appears only in the China National Basic Medical Insurance Drug List and China National Essential Drug List. The evaluation results obtained using the Eff-iEC method align with Medical Community Recognition, providing an objective and comprehensive assessment of Xiaoyao San's efficacy. The findings suggest that Xiaoyao San has strong evidence for treating depression and menopausal syndrome. However, further experimental and clinical trials are needed to assess its efficacy in treating premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, and dyspepsia. These results support the clinical efficacy and rational use of Xiaoyao San, expand the application scope of the Eff-iEC method, and offer valuable insights and methodological references for the comparative evaluation of multifunctional TCM formulas.

Objective To construct programmed cell death protein-ligand 1(PD-LI)^hi tolerogenic dendritic cell (tol-DC) derived from bone marrow of DA rats and identify its immunological function. Methods DA rat bone marrow cells were extracted, combined with recombinant mouse granulocyte macrophage colony-stimulating factor and recombinant mouse interleukin (IL)-4, and cultured for 6 days in vitro to induce the differentiation of bone marrow cells into immature dendritic cells (imDC). Lipopolysaccharide was used to stimulate cell maturation and cultured for 2 days to collect mature dendritic cells (mDC). PD-L1 lentiviral vector virus stock solution or equivalent dose lentiviral stock solution was added, and PD-L1^hitol-DC and Lv-imDC were collected after culture for 2 days. The morphology of PD-L1^hitol-DC was observed by inverted phase contrast microscope and transmission electron microscope. Real-time fluorescence quantitative reverse transcription polymerase chain reaction, Western blotting and flow cytometry were used to detect the expression level of specific markers on cell surface. CD8⁺T cells derived from Lewis rat spleen were co-cultured with imDC, mDC, Lv-imDC and PD-L1^hitol-DC, respectively. The levels of inflammatory factors in the supernatant of each group were detected by enzyme-linked immunosorbent assay. The apoptosis of T cells and the differentiation of regulatory T cells (Treg) in each group were analyzed by flow cytometry. Results The morphology of PD-L1^hitol-DC modified by PD-L1 gene was consistent with tol-DC characteristics, and the expression levels of CD80, CD86 and major histocompatibility complex (MHC) on the surface were low. After mixed culture with CD8⁺ T cells, the levels of IL-10 and transforming growth factor (TGF) -β1 in the supernatant of PD-L1^hitol-DC group were higher, the levels of tumor necrosis factor (TNF) -α and IL-17A were lower, and the apoptosis of T cells and Treg differentiation were increased. Conclusions Overexpression of PD-L1 through lentiviral vectors may successfully induce the construction of bone-marrow derived PD-L1^hitol-DC in DA rats, promote the secretion of anti-inflammatory factors and T cell apoptosis, induce the differentiation of Treg, and inhibit the immune response of allogeneic CD8⁺T cells, which provides experimental basis for the next organ transplantation immune tolerance study.

PURPOSE: Hidden blood loss (HBL) during the perioperative period significantly impacts postoperative recovery and complications, yet it is frequently disregarded. This study aimed to investigate the effects of tip-apex distance (TAD) and calcar-referenced tip-apex distance (calTAD) on HBL in the treatment of intertrochanteric fractures utilizing proximal femoral nail antirotation (PFNA). The study also seeks to evaluate the possible decrease in HBL subsequent to PFNA treatment by optimizing nail positioning. METHOD: A historical cohort study was conducted from January 2020 to December 2022. Patients diagnosed with unilateral acute closed femoral intertrochanteric fracture and who underwent PFNA internal fixation surgery met the inclusion criteria, and were grouped according to the value of calTAD and TAD. The participants were divided into low TAD group (TAD<20 mm) and high TAD group (TAD≥20 mm); low calTAD group (calTAD<7.625 mm) and high calTAD group (calTAD≥7.625 mm), respectively. The primary outcome measures were intraoperative blood loss (including HBL, overt blood loss, and total blood loss). Continuous data were analyzed using an independent sample t-test or Mann-Whitney U test, and categorical data were analyzed using the Pearson Chi-square test. Univariate analysis was used to evaluate the association between various indicators and perioperative HBL. A stepwise multiple linear regression analysis model was used to determine the independent factors affecting perioperative HBL. A p value less than 0.05 was considered statistically significant. RESULTS: A total of 131 patients were initially included, of which 80 were assigned to the calTAD group (with 61 in the high calTAD group and 19 in the low calTAD group), and 80 were assigned to the TAD group (with 34 in the high TAD group and 46 in the low TAD group). The average HBL for the low TAD group was 772.85 mL, whereas for the high TAD group it was 919.68 mL (p>0.05). The average HBL for the low calTAD group was 611.42 mL, whereas for the high calTAD group it was 904.97 mL (p<0.05). Subsequent analysis revealed that the patient's height, preoperative hemoglobin levels, changes in hemoglobin and hematocrit levels from pre- to post-surgery, and calTAD are independent risk factors influencing HBL. CONCLUSION In summary, our investigation revealed a significant correlation between the positioning of nails in PFNA and HBL during the perioperative period. By optimizing the placement of the cephalic nail, specifically by ensuring a calTAD of less than 7.625 mm, a significant decrease in HBL can be attained. Additionally, we identified that height, preoperative hemoglobin, differences in preoperative and postoperative hemoglobin and hematocrit, and the positioning of the cephalic nail were independent risk factors for HBL.
