Objective:To explore the short-term efficacy of fixation with a 3D printed individualized custom-made plate in the treatment of elderly patients with periprosthetic femoral fracture.Methods:Retrospectively analyzed were the 5 elderly patients with periprosthetic femoral fracture who had been treated by fixation with a 3D printed individualized custom-made plate from January 2022 to July 2022 at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital. There were 3 males and 2 females, aged 81, 86, 77, 91 and 87 years, respectively. One left and 4 right limbs were affected. Vancouver classification: type B1 ( n=3), type B2 ( n=1), and type C ( n=1). The time from operation to injury was 5, 6, 10, 5 and 7 days, respectively. Preoperatively, the femur affected, prosthesis and individualized plate with a greater trochanteric hook, loop cable channel and bone-like trabecular microporous structure were custom-made by 3D printing according to 1:1 models. Virtual operations were simulated to formulate surgical protocols. The operation time, length of surgical incision, intraoperative blood loss and transfusion, hospital stay, hip function and complications at the last follow-up were recorded. Results:The 5 patients were followed up for 12, 7, 10, 3 and 6 months, respectively. There were no events of superficial incision or deep prosthesis infection. Respectively, the operation time was 1.8, 1.7, 2.3, 2.0 and 3.3 h; the length of surgical incision 31, 30, 38, 27 and 30 cm; the intraoperative bleeding volume 400, 300, 300, 500 and 600 mL; the length of hospital stay 8, 9, 15, 14 and 11 d. Four patients received intraoperative blood transfusion of 300, 900, 150 and 1, 050 mL, respectively. One patient died of a heart attack 3 months after discharge; another patient developed dyskinesia at the contralateral limb 3 months after discharge due to cerebral infarction and died of recurrent cerebral infarction 7 months after discharge. At the last follow-up, the Harris hip scores of 3 patients were 86, 77 and 69 points, respectively. None of the patients had complications like breakage or loosening of implants.Conclusion:In the treatment of elderly patients with periprosthetic femoral fracture, fixation with a 3D printed individualized custom-made plate may lead to fine limb function and good short-term curative efficacy.

Objective To investigate the mechanism of action of Dingchuan granules in intervening respiratory syncytial virus pneumonia based on network pharmacology and animal experiments.Methods The potential active ingredients and targets of each traditional Chinese medicine in Dingchuan granules were obtained from TCMSP and TCMID databases,and the active ingredients of the drugs in Dingchuan granules were screened according to ADME pharmacokinetic parameters;the potential disease targets of respiratory syncytial virus pneumonia were obtained from Genecards,OMIM,and DisGeNet databases;the protein-interaction networks of intersecting targets were visualized by using String platform;the key core targets were visualized by using David database;and the intersection targets were visualized by using David database.Interaction networks were constructed using the String platform to visualize the intersecting targets;GO functional enrichment and KEGG pathway enrichment analyses of the key core targets were performed using the David database;and then the relevant networks for the intervention of Respiratory Syncytial Virus Pneumonia in the Dingchuan particles were constructed using the Cytoscape software(3.9.1).Respiratory syncytial virus(RSV)-induced respiratory syncytial virus pneumonia in young rats was selected for experimental validation.Results The results of the network pharmacology showed that the 177 potential active ingredients of Dingchuan granules acted on 144 targets,and there were 1075 targets related to respiratory syncytial virus pneumonia,and 55 drug-disease intersecting targets were obtained,of which 25 core targets were ALB,IL6,CASP3,EGFR,VEGFA,etc.The GO function of Dingchuan granules was also investigated,and the GO function of Dingchuan was investigated.The results of GO function enrichment analysis showed that the biological processes involved mainly include positive regulation of transcription,positive regulation of RNA polymerase II promoter transcription,positive regulation of gene expression,negative regulation of apoptosis,etc.The KEGG pathway enrichment mainly involves the PI3K-Akt signaling pathway,the cancer pathway,the tumor necrosis factor signaling pathway,the IL-17 signaling pathway and so on.The KEGG pathway enrichment mainly involves PI3K-Akt signaling pathway,tumor necrosis factor signaling pathway,IL-17 signaling pathway,etc.Animal experiments initially showed that the fixed wheezing granules can play a role in inflammation and immune response by regulating the PI3K-Akt signaling pathway,thus participating in the inflammatory and immune response.Compared with the normal group,the ratios of p-PI3K/PI3K and p-Akt/Akt in the lung tissues of young rats in the model group were significantly higher(P<0.05),the viral load was significantly higher(P<0.05),the pathological score of lung tissue damage was significantly higher(P<0.05),and the content of inflammatory factors IL-6 and TNF-α in alveolar lavage fluid(BALF)was significantly higher(P<0.05).Compared with the model group,the expression of p-PI3K/PI3K and p-Akt/Akt proteins in the lung tissues of young rats in each dose group and the positive control group was reduced(P<0.05),the viral load was significantly reduced(P<0.05),the pathological scores of lung tissue injury were significantly reduced(P<0.05),and the contents of inflammatory factors IL-6 and TNF-α in BALF were significantly reduced(P<0.05).Conclusion The study revealed the synergistic mechanism of multi-component,multi-target,and multi-pathway action of Dingchuan granules for the treatment of respiratory syncytial virus pneumonia.It was verified by animal experiments that RSV infection in young rats probably activated the PI3K-Akt signaling pathway,which caused the release of inflammatory factors IL-6 and TNF-α.Dingchuan granules could effectively down-regulate the PI3K-Akt signaling pathway,inhibit the release of inflammatory factors IL-6 and TNF-α,and thus achieve the anti-inflammatory effect.

Objective:To examine the effect of anemia on the prognosis of elderly patients with acute coronary syndrome.Methods:We searched PubMed, Scopus, OVID, the Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure, China Biology Medicine Disc, the WanFang and Weipu databases for studies on the association between anemia and the prognosis of acute coronary syndrome in elderly patients.The date range included the period from the establishment of the database to December 10, 2022.Two reviewers independently completed the literature screening and data extraction according to the inclusion and exclusion criteria for the literature.Stata 16.0 software was used to analyze the data.Results:Of 1 399 references retrieved from the initial search, 13 met the inclusion criteria, including a total of 9540 patients with a mean age of 70.3 years.2872 of these patients had concurrent anemia and 6 668 patients had no anemia.In elderly patients with acute coronary syndrome, those with anemia showed significantly increased risk of death, compared with those with no anemia( RR=2.28, 95% CI: 1.74-3.00). Anemia also increased the incidence of ischemia( RR=1.36, 95% CI: 1.13-1.64)and bleeding events( RR=2.18, 95% CI: 1.59-3.01)( P<0.05 for all). Conclusions:Anemia significantly increases the risk of death and is associated with poor prognosis in elderly patients with acute coronary syndrome.
