This study established the HPLC fingerprints, characteristic chromatograms, and a multi-component content determination method for Bidens bipinnata and B. biternata. The chemical pattern recognition analysis was then employed to clarify the characteristic indexes of quality differences between the two original plants of Bidentis Herba, providing a reference for establishing the quality standards of Bidentis Herba. HPLC was launched on an Agilent Poroshell 120 EC-C_(18) chromatographic column(4.6 mm×250 mm, 4 μm) by gradient elution with a mobile phase of 0.1% aqueous phosphoric acid-acetonitrile at a flow rate of 0.7 mL·min~(-1), detection wavelength of 270 nm, column temperature of 25 ℃, and an injection volume of 5 μL. The similarity between the fingerprints of 18 batches of Bidentis Herba samples and the common pattern(R) ranged from 0.572 to 0.933. A total of 23 chromatographic peaks were calibrated. Through comparison with the reference substances, six components(neochlorogenic acid, chlorogenic acid, isochlorogenic acid A, isochlorogenic acid B, rutin, and hyperoside) were identified and subjected to quantitative analysis. The characteristic fingerprints of B. bipinnata and B. biternata were calibrated with 20 and 17 characteristic peaks, respectively. Among them, peaks 8, 9, 22, and 23 were the characteristic peaks of B. bipinnata, and peak 7 was the characteristic peak of B. biternata, which can be used to distinguish the two original plants of Bidentis Herba. The relative standard deviation of the content of the above-mentioned six components ranged from 36% to 123%. The cluster analysis, principal component analysis, and orthogonal partial least squares-discriminant analysis(OPLS-DA) classified the 18 batches of Bidentis Herba samples into two categories. Additionally, through the analysis of variable importance in projection(VIP) under OPLS-DA, three characteristic indexes, rutin, isochlorogenic acid A, and isochlorogenic acid B, were identified. The analytical method established in this study can comprehensively evaluate the consistency of Bidentis Herba samples derived from different original plants, specifically identify the differential components between them, and effectively distinguish the two original plants of Bidentis Herba, providing a basis for the differentiation between different original plants and the quality control of Bidentis Herba.

OBJECTIVE: To investigate the short-term clinical effect of closed reduction single arm external fixator combined with percutaneous needle fixation in the treatment of C1 distal radius fracture in elderly patients. METHODS: Between December 2022 and December 2023, a total of 60 elderly patients diagnosed with type C1 distal radius fractures were treated, comprising 9 males and 51 females. The age ranged from 65 to 84 years old, with an average of (72.69±8.14) years old. Among them, there were 18 cases on the left side and 42 cases on the right side. There were 55 cases of falling injury and 5 cases of traffic accident injury. According to the different surgical methods, the patients were divided into observation group and control group, with 30 cases in each group. The control group underwent manual reduction and unilateral external fixator fixation, consisting of 4 males and 26 females. The mean age was (72.54±8.67) years old. The body mass index (BMI) was (20.61±2.17) kg·m^-2. There were 10 cases on the left side and 20 cases on the right side. Among them, there were 27 cases of falling injury and 3 cases of traffic accident injury. The observation group was treated with manual reduction and unilateral external fixator combined with percutaneous Kirschner wire fixation, including 5 males and 25 females. The mean age was (72.76±7.23) years old. BMI (20.82±2.03) kg·m^-2. The left side was involved in 8 cases and the right side in 22 cases. There were 28 cases of falling injury and 2 cases of traffic accident injury. The changes in radial height, ulnar declination, palmar inclination angle parameters and patient-rated wrist evaluation (PRWE) were assessed on X-ray films before surgery, 2 days after surgery, and 12 weeks after surgery between the two groups. RESULTS: All surgical procedures were successfully completed in both groups without any significant complications. All patients were followed up for a duration from 12 to 20 weeks with an average of(14.50±2.78) weeks. The two groups exhibited significant differences in radial height, palmar inclination angle, and ulnar deviation angle at 2 days and 12 weeks post-operation (P<0.05). However, there was no statistically significant difference observed in radial height, palmar inclination, and ulnar deviation between the two groups at 2 days after the operation (P>0.05). There were significant differences in radial height, palmar inclination angle, and ulnar deviation between the two groups at 12 weeks after operation (P<0.05). At 2 days and 12 weeks after the operation, there were significant differences in PRWE scores of the two groups compared with preoperative scores(P<0.05). At 2 days after the operation, there was no significant difference in PRWE score between the two groups (P>0.05). The PRWE score showed a significant difference between the two groups at 12 weeks post-operation(P<0.05). CONCLUSION The combination of closed reduction and unilateral external fixator, along with percutaneous pin fixation provides move stable fixation for type C1 distal radius fractures. Gradual removal of external fixator further facilitatse the recovery of wrist joint function.

OBJECTIVE: Psoriasis, a common chronic inflammatory skin condition with genetic underpinnings, is traditionally managed with cupping therapy. Although used historically, the precise mechanical effects and therapeutic mechanisms of cupping in psoriasis remain largely unexamined. This study aimed to evaluate cupping therapy's efficacy for psoriasis and investigate its role in modulating inflammatory responses and cellular metabolism. METHODS: Psoriasis was induced in mice using topical imiquimod (IMQ). The effects of cupping on psoriatic lesions were assessed using the Psoriasis Area and Severity Index score, histology, immunohistochemistry, and immunofluorescence staining. polymerase chain reaction sequencing (RNA-seq) and Western blotting were conducted to examine changes in mRNA expression and the AMP-activated protein kinase (AMPK) signaling pathway. RESULTS: Cupping therapy significantly reduced inflammation, epidermal thickness, and inflammatory cell infiltration in mice with IMQ-induced psoriasis. Immunohistochemistry and immunofluorescence showed lower expression of inflammatory markers and a shift in T-cell populations. RNA-seq and Western blotting indicated that cupping upregulated Piezo1 and activated the AMPK pathway, improving energy metabolism in psoriatic skin. CONCLUSION Cupping therapy reduces epidermal hyperproliferation and inflammation in psoriasis, rebalancing the local immune microenvironment. Mechanistically, cupping promotes calcium influx via Piezo1, activates AMPK signaling, and supports metabolic homeostasis, suggesting therapeutic potential for psoriasis.

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

Objective To assess the clinical effect of the Yiqi Huoxue Huazhuo therapy(the therapy for replenishing qi,activating blood and resolving turbidity)for the treatment of hepatic fibrosis in Wilson's disease(WD,also known as hepatolenticular degeneration).Methods Using retrospective research method,52 patients with liver fibrosis in WD of qi deficiency and blood stasis type were divided into 24 cases in the control group and 28 cases in the treatment group according to the treatment method.The control group was treated with conventional decopper therapy with western medicines,and the treatment group was treated with Chinese herbal decoction based on Yiqi Huoxue Huazhuo therapy together with conventional decopper therapy.Both groups were treated for a total of 4 weeks.Before and after the treatment,the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome scores,Unified Wilson's Disease Rating Scale(UWDRS)hepatic symptom scores,serum levels of liver fibrosis indicators of pre-collagen typeⅢ(PCⅢ),hyaluronic acid(HA),collagenⅣ(CⅣ),and laminin(LN),C-X-C motif chemokine ligand 10(CXCL10)level,and the point shear-wave elastography(pSWE)values of hepatic ultrasound based on acoustic radiation force impulse imaging(ARFI).After treatment,the clinical efficacy of the two groups was evaluated.Results(1)After 4 weeks of treatment,the total effective rate of the treatment group was 85.71%(24/28),while that of the control group was 54.17%(13/24),and the intergroup comparison(tested by chi-square test)showed that the therapeutic efficacy of the treatment group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the TCM syndrome scores in both groups were decreased compared with those before treatment(P＜0.01),and the decrease of TCM syndrome scores in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the UWDRS liver symptom scores in the two groups were decreased compared with those before treatment(P＜0.01),but the difference was not statistically significant when comparing between the two groups after treatment(P＞0.05).(4)After treatment,serum levels of liver fibrosis indicators of HA,LN,CⅣ and PCⅢ in the treatment group were all decreased compared with those before treatment(P＜0.01),while in the control group only serum LN and PCⅢlevels were decreased(P＜0.05).The intergroup comparison showed that the decrease of serum HA,LN,and PCⅢlevels in the treatment group was superior to that in the control group(P＜0.05 or P＜0.01),while the decrease of serum CⅣlevel tended to be superior to that in the control group,but the difference was not statistically significant(P＞0.05).(5)After treatment,the serum chemokine CXCL10 level in the treatment group was significantly decreased compared with that before treatment(P＜0.01),while the level tended to decrease in the control group,but the difference was not statistically significant(P＞0.05).The intergroup comparison showed that the reduction of serum CXCL10 level in the treatment group was significantly superior to that in the control group(P＜0.05).(6)After treatment,the pSWE values of hepatic ultrasound in the two groups were lower than those before treatment(P＜0.01),and the reduction of pSWE values in treatment group was significantly superior to that of the control group(P＜0.01).Conclusion Yiqi Huoxue Huazhuo therapy can effectively reduce the TCM syndrome scores of WD patients,improve the UWDRS hepatic symptom scores,down-regulate the liver fibrosis indicator level and serum CXCL10 expression level,reduce the pSWE values of hepatic ultrasound,and enhance the clinical efficacy.

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 develop a deep learning model for automated age estimation based on 3D CT reconstructed images of Han population in western China,and evaluate its feasibility and reliability.Methods The retrospective pelvic CT imaging data of 1 200 samples(600 males and 600 females)aged 20.0 to 80.0 years in western China were collected and reconstructed into 3D virtual bone models.The images of the ischial tuberosity feature region were extracted to create sex-specific and left/right site-specific sample libraries.Using the ResNet34 model,500 samples of different sexes were randomly selected as training and verification set,the remaining samples were used as testing set.Initialization and transfer learning were used to train images that distinguish sex and left/right site.Mean absolute error(MAE)and root mean square error(RMSE)were used as primary indicators to evaluate the model.Results Prediction results varied between sexes,with bilateral models outperformed left/right unilateral ones,and transfer learning models showed superior performance over initial models.In the prediction results of bilateral transfer learning models,the male MAE was 7.74 years and RMSE was 9.73 years,the female MAE was 6.27 years and RMSE was 7.82 years,and the mixed sexes MAE was 6.64 years and RMSE was 8.43 years.Conclusion The skeletal age estimation model,utilizing is-chial tuberosity images of Han population in western China and employing the ResNet34 combined with transfer learning,can effectively estimate adult ischium age.

Objective To describe the current state of research and future research hotspots through a metrological analysis of the literature in the field of forensic anthropological remains identification re-search.Methods The data retrieved and extracted from the Web of Science Core Collection (WoSCC),the core database of the Web of Science information service platform (hereinafter referred to as "WoS"),was used to analyze the trends and topic changes in research on forensic identification of human re-mains from 1991 to 2022.Network visualisation of publication trends,countries (regions),institutions,authors and topics related to the identification of remains in forensic anthropology was analysed using python 3.9.2 and Gephi 0.10.Results A total of 873 papers written in English in the field of forensic anthropological remains identification research were obtained.The journal with the largest number of publications was Forensic Science International (164 articles).The country (region) with the largest number of published papers was China (90 articles).Katholieke Univ Leuven (Netherlands,21 articles) was the institution with the largest number of publications.Topic analysis revealed that the focus of forensic anthropological remains identification research was sex estimation and age estimation,and the most commonly studied remains were teeth.Conclusion The volume of publications in the field of forensic anthropological remains identification research has a distinct phasing.However,the scope of both international and domestic collaborations remains limited.Traditionally,human remains identifica-tion has primarily relied on key areas such as the pelvis,skull,and teeth.Looking ahead,future re-search will likely focus on the more accurate and efficient identification of multiple skeletal remains through the use of machine learning and deep learning techniques.

Shiwei-Ruxiang-capsule (SWRXC) is a classic formulation widely used in the treatment of rheumatoid arthritis (RA). The study used liquid chromatography-tandem mass spectrometry (LC-MS/MS) serum untargeted metabolomics and high-throughput 16S rRNA gene sequencing association analysis to elucidate the mechanism of action of SWRXC for the treatment of Freund's complete adjuvant-induced RA. The results showed that SWRXC significantly improved symptoms and reduced serum cytokine levels in RA rats. Based on LC-MS/MS technology, metabolomics identified tryptophan metabolism, nucleotide metabolism and purine metabolism as the most relevant pathways for treatment. In addition, 16S rRNA sequencing results showed that SWRXC could ameliorate RA-induced intestinal microbial oncogenesis in rats. In conclusion, SWRXC can improve the morphology and structure of RA joint tissues, reduce serum factor levels, and may play a role in improving RA by modulating related metabolic pathways such as tryptophan metabolism, nucleotide metabolism and purine metabolism, and altering the composition of intestinal flora. Animal protocols were approved by the Animal Ethics Committee of Qinghai Normal University (No. 2021041203).

Objective: To investigate the clinical and molecular biological characteristics of patients with accelerated chronic lymphocytic leukemia (aCLL) . Methods: From January 2020 to October 2022, the data of 13 patients diagnosed with aCLL at The First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed to explore the clinical and molecular biological characteristics of aCLL. Results: The median age of the patients was 54 (35-72) years. Prior to aCLL, five patients received no treatment for CLL/small lymphocytic lymphoma (SLL), while the other patients received treatment, predominantly with BTK inhibitors. The patients were diagnosed with aCLL through pathological confirmation upon disease progression. Six patients exhibited bulky disease (lesions with a maximum diameter ≥5 cm). Positron emission tomography (PET) -computed tomography (CT) images revealed metabolic heterogeneity, both between and within lesions, and the median maximum standardized uptake value (SUVmax) of the lesion with the most elevated metabolic activity was 6.96 (2.51-11.90). Patients with unmutated IGHV CLL accounted for 76.9% (10/13), and the most frequent genetic and molecular aberrations included +12 [3/7 (42.9% ) ], ATM mutation [6/12 (50% ) ], and NOTCH1 mutation [6/12 (50% ) ]. Twelve patients received subsequent treatment. The overall response rate was 91.7%, and the complete response rate was 58.3%. Five patients experienced disease progression, among which two patients developed Richter transformation. Patients with aCLL with KRAS mutation had worse progression-free survival (7.0 month vs 26.3 months, P=0.015) . Conclusion: Patients with aCLL exhibited a clinically aggressive course, often accompanied by unfavorable prognostic factors, including unmutated IGHV, +12, ATM mutation, and NOTCH1 mutation. Patients with CLL/SLL with clinical suspicion of disease progression, especially those with bulky disease and PET-CT SUVmax ≥5, should undergo biopsy at the site of highest metabolic uptake to establish a definitive pathological diagnosis.
