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 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.

Objective To investigate the effect and underlying mechanism of SULT2B1 in the de-velopment of atherosclerosis(AS).Methods Twelve 8-week-old apolipoprotein E-knockout(apoE-/-)male mice were subjected and fed with a high-fat diet for 12 weeks,and then randomly divided into adeno-associated virus(AAV)-GFP and AAV-shSULT2B1 groups,with 6 animals in each group.In 4 weeks after AAV injection via tail vein,the mice were sacrificed for assessing aortic and aortic root plaque formation by oil red O staining and detecting serum levels of inflam-matory factors and blood lipids.RAW264.7 cells were transfected with adenovirus(Ad)-GFP and Ad-SULT2B1,respectively(n=3).RNA sequencing was performed to detect downstream RNA changes.Then LncRNA gga3-204 was selected for downstream study.After RAW264.7 cells were divided into si-NC group,si-SULT2B1 group,si-Lncgga3-204 group and si-SULT2B1+si-Lncg-ga3-204 group(n=3),and the IL-1β and IL-6 levels were detected in these transfected cells.Results There was no statistically difference in body weight in the mice from the AAV-GFP and AAV-shSULT2B1 groups after high-fat feeding(P＞0.05).Significantly lower serum levels of TC,TG and LDL-C,reduced aortic plaque area[(8.38±1.33)％vs(11.83±1.04)％,P=0.000],and decreased TG content within the aortic root plaque[(12.29±1.54)％vs(17.67±1.53)％,P=0.000]were observed in the AAV-shSULT2B1 group than those in the AAV-GFP group.Ser-um IL-1β and IL-6 levels in the mice of the AAV-shSULT2B1 group than those in the AAV-GFP group(P＜0.01).The AAV-shSULT2B1 group also had obviously lower serum levels of I L-1 βand IL-6 than the AAV-GFP group(P＜0.01).In the RAW264.7 cells from the si-SULT2B1 group,the mRNA levels of IL-1β and IL-6 were notably lower than those in the si-NC group(P＜0.01).LncRNA gga3-204 expression was significantly higher in the Ad-shSULT2B1 group than the Ad-GFP group(P＜0.01).While,the si-SULT2B1 group had statistically higher Lncgga3-204 level than the si-NC group(2.32±0.60 vs 1.19±0.21,P=0.036).The si-Lncgga3-204 group had significantly higher IL-1β and IL-6 mRNA levels than the si-NC group(P＜0.01).The si-SULT2B1+si-Lncgga3-204 group had significantly higher IL-1β and IL-6 mRNA levels than the si-SULT2B1 group(P＜0.05).Conclusion SULT2B1 affects the macrophage inflammatory response via Lncgga3-204,and then affects the progression of AS.
