ObjectiveTo explore the mechanism of Yishen Qubi Tongluo Formula （益肾祛痹通络方， YQTF） in the treatment of rheumatoid arthritis（RA）. MethodsNetwork pharmacology was employed to retrieve and screen the active components and potential targets of YQTF as well as RA-related targets using databases including TCMSP， BATMAN， ETCM and GEO. The intersection of targets related to active components and RA-related targets was identified， and a protein-protein interaction （PPI） network was constructed. Gene Ontology （GO） functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were performed， and a drug-active component-common target network of YQTF in the treatment of RA was established. The core components of YQTF were molecularly docked with key targets. Human rheumatoid arthritis synovial fibroblast cell line MH7A was divided into blank group， model group， methotrexate group and YQTF group. The blank group was cultured with 10% fetal bovine serum， while the other three groups were stimulated with 10 μg/L of recombinant human tumor necrosis factor-α （TNF-α） for 24 h to establish the RA cell model. On this basis， the methotrexate group was treated with methotrexate suspension at a concentration of 20 μmol/L， and the YQTF group was treated with 10% YQTF-medicated serum. After 48 h of intervention， the levels of TNF-α and interleukin-17A（IL-17A）contents in cell supernatants were detected by enzyme-linked immunosorbent assay （ELISA）， and mRNA expressions of phosphatidylinositol 3-kinase（PI3K）， protein kinase B（AKT） and mammalian target of rapamycin（mTOR） were detected by real-time quantitative polymerase chain reaction （RT-qPCR）. ResultsNetwork pharmacological analysis identified 209 active components and 583 potential target genes of YQTF， as well as 818 RA-related targets. A total of 29 common targets were obtained from the intersection of drug-related targets and RA-related targets. Quercetin，β-sitosterol， kaempferol， stigmasterol and luteolin were the core active components of YQTF for the treatment of RA， while matrix metalloproteinase-9 （MMP9）， prostaglandin-endoperoxide synthase 2 （PTGS2）， Toll-like receptor 4 （TLR4）， tumor protein p53 （TP53） and transcription factor AP-1 subunit JUN were the key targets. The GO and KEGG pathway enrichment analysis showed that the involved biological processes and pathways were mainly associated with antioxidant responses， PI3K-AKT signaling pathway and Toll-like receptor （TLR） signaling pathway. Molecular docking results showed that MMP9 and PTGS2 exhibited high binding affinities with quercetin， β-sitosterol， kaempferol， stigmasterol and luteolin； TLR4 exhibited high binding activities with β-sitosterol， stigmasterol and luteolin； and TP53 showed high binding affinity with luteolin. The results of cell experiments showed that compared with the control group， the contents of TNF-α and IL-17A as well as the mRNA expressions of AKT and mTOR in the model group significantly increased （P＜0.05 or P＜0.01）. Compared with the model group， all the above indicators significantly decreased in the YQTF group， while the contents of TNF-α and the mRNA expression of AKT significantly decreased in the methotrexate group （P＜0.05 or P＜0.01）. ConclusionThe mechanism of YQTF in the treatment of RA may be associated with reducing inflammatory cytokine secretion and inhibiting the activation of the PI3K-AKT-mTOR signaling pathway.

Objective: To analyze the structural changes in whole blood and apheresis platelet donations in Chinese Society of Blood Transfusion (CSBT) sentinel units from 2021 to 2025, and to provide evidence for donor recruitment and blood service management. Methods: Aggregated data reported by sentinel sites were collected and stratified according to six indicators: age, sex, donation history, donation volume, donation site, and organization mode. Pearson χ test, Cramer′V coefficient, Cochran-Armitage trend test and simple linear regression were adopted for analysis. Results: A total of 16 256 973 whole blood donations and 1 576 546 apheresis platelet donations were included. Among whole-blood donations, the proportion of donors aged 18-22 years decreased from 27.30% to 10.60%. The proportion of male donors increased from 58.81% to 63.13%; the proportion of people aged 30 and above increased from 58.40% to 75.30%; the proportion of fixed locations rose from 28.37% to 36.57%; the proportion of social groups increased from 21.69% to 39.69%. The 400-mL donations decreased from 62.12% to 53.46%, while individually initiated voluntary donations remained above 50%. Apheresis platelet donations were predominantly from males, individuals aged 30-39 years, and repeat donors; 2-treatment-unit apheresis platelet donations increased from 67.19% to 74.93%, and individually initiated donations accounted for 92.97%-96.02%. Statistically significant overall annual compositional differences were observed for all six indicators (all P<0.001), whereas linear trends for some sub-categories were not statistically significant. Conclusion: In the participating CSBT sentinel units, among whole blood donations, the proportions of donors aged 18-22 years, university-organized group donations, and donations at blood mobiles decreased, whereas the proportions of organizational group donations and donations at fixed venues increased. The apheresis platelet donation cohort is relatively mature and is evolving toward a high-efficiency donation model. Individual voluntary donation remains the primary organization mode for both donation types. Strategies such as youth donor recruitment, optimized layout of fixed donation sites, and retention of repeat donors should be strengthened to improve the resilience of blood supply.

Objective:To explore the value of magnetic resonance examination in distinguishing invasive and non-invasive pancreatic solid pseudopapillary neoplasms (SPN).Methods:The clinical and MRI data of 167 patients with SPN who underwent surgery and were pathologically diagnosed at Zhongshan Hospital ,Fudan University from Oct 2013 to Oct 2023 were retrospectively analyzed.Results:There was no statistically significant difference between invasive and non-invasive SPN in terms of age, gender, clinical symptoms, laboratory tests, location, growth pattern, tumor size, relationship with the pancreas, bleeding, and pancreatic duct dilation ( P>0.05). However, there were statistically significant differences between the two groups in terms of tumor morphology, margins, capsule, cystic solid ratio, pancreatic atrophy, enhancement pattern, and enhancement features ( P<0.05). The area under the ROC curve for the combined indicators (tumor morphology, margins, capsule, cystic solid ratio, and pancreatic atrophy) was 0.679 (95% CI: 0.594-0.764), with a sensitivity of 73.7% and specificity of 70.9%. Conclusion:Magnetic resonance examination is helpful in distinguishing invasive and non-invasive pancreatic solid pseudopapillary neoplasms.

Acupuncture and moxibustion have their unique advantages in treating tumors,but the theoretical framework of acupuncture and moxibustion intervention in tumors needs to be improved,and the academic system still needs to be sorted out.In this paper,we try to describe the commonalities between Chinese medical theories and modern medical technologies in order to consolidate the theoretical foundation of acupuncture intervention in tumor.Specifically:① Acupuncture regulates immune function and energy metabolism,which is a specific form of tonifying the spleen and stomach to support positive qi.② Tumors belong to the broad definition of"sores and ulcers"in traditional Chinese medicine,which is a special kind of chronic inflammation,and acupuncture intervenes in tumors by intervening in inflammatory reactions from ulcers.③ Tumor is a"dynamic pseudo-organ"with yin and yang attributes and"life attributes".Acupuncture and moxibustion can regulate various cells and factors in the tumor environment in a multi-targeted way,so as to make it tend to the state of yin and yang equilibrium.④ Acupuncture and moxibustion have unique advantages in the reduction of toxicity,enhancement of efficacy,tonicity,rejuvenation,treatment of complications,etc.,which complement the allopathic therapies of modern medicine,and can help to realize survival with tumors.

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 investigate the clinical effect of perforator flap of distal cutaneous perforator of medial plantar artery in recon struction of destructive defect in the base plane of proximal phalange of great toe.Methods:Twenty-six patients were treated in the Department of Foot and Ankle Surgery of Xuzhou Renci Hospital from September 2017 to December 2021. The patients were 24 males and 2 females, aged 26 to 60 years old. There were 12 defects in left foot and 14 in right foot. All the defects were the residual wounds at the first metatarsophalangeal joint with the defect at 2.0 cm × 3.0 cm - 4.0 cm × 5.0 cm in size. The flaps pedicled with distal cutaneous perforator of the medial plantar artery were used to repair the defects, with a size at 3.2 cm× 4.2 cm in average. Skin grafts were employed to repair the donor sites. Postoperative patient management including lifting the affected limbs and keeping warm, anti-infection, detumescence, anti-coagulation and pain relief.Results:All patients were entered in postoperative follow-up at outpatient clinic for 1-3 years. Twenty-two flaps survived after surgery, except 4 that had dark purple edge indicating venous congestion. Blood supply of the flap was regained after the tension of the flap was relieved by interval suture removal. Appearance of flaps was good, without obvious swelling nor pigmentation, good in elasticity, in hard texture and with good wear resistance. Patients showed no limp of the affected limbs, and without restriction in wearing shoes or walking. The function of feet was evaluated according to the American Orthopedic Foot and Ankle Societ (AOFAS) I50, with 24 patients in excellent and 2 in good.Conclusion:The anatomy of the flap pedicled with distal cutaneous perforator of the medial plantar artery is relatively constant. It provides a blood supply and does not affect the trunk of major artery. The flap has a thick skin cuticle hence it is wear-resistant. This flap provides a choice to the repair of a defect at proximal segment of great toe.

Objective To compare the clinical efficacy between air-free trans-axillary laparoscopic thyroidectomy and open thyroidectomy. Methods A retrospective analysis was performed on the data of both 96 patients who underwent air-free trans-axillary laparoscopic thyroidectomy (laparoscopic group) and 232 patients who underwent open thyroidectomy (open group) from August 2015 to July 2020. Comparative analysis were performed on operative data, the postoperative data of recovery and complications between two groups. Results The operative time in laparoscopic group was longer significantly than that in open group [(168±23) min vs. (95±18) min, P=0.022]. There was no significantly difference in the rate of recognition of recurrent laryngeal nerve between two groups (100.0% vs. 99.1%, P=0.138). The rate of recognition of both superior (98.0% vs. 97.0%, P=0.003) and inferior parathyroid glands (95.8% vs. 99.1%, P=0.028) in laparoscopic group was higher significantly than those in open group. The amount of drain of the first day after operation in laparoscopic group was more significantly than that in open group[(42±22) mL vs. (25±10) mL, P=0.006]. The postoperative length of hospital stay in laparoscopic group was longer significantly [(2.8±0.6) d vs. (1.8±1.2) d, P=0.016]. The cost of hospital stay was (13 186±1 015) yuan vs. (12 632±1 456) yuan （P=0.365） and the rate of postoperative complication was 10.4% vs. 9.1%（P=0.126）, which all showed no significant difference between two groups. Conclusions Air-free trans-axillary laparoscopic thyroidectomy could be feasible and safe, and have better appearance. However, both operative time and hospital stay were longer.
