BACKGROUND:In recent years,tranexamic acid has been extensively used to mitigate the substantial blood loss associated with total knee arthroplasty.However,the optimal method of topical application has not yet been established. OBJECTIVE:To evaluate the effectiveness and safety of intraoperative topical application of tranexamic acid combined with physical compression dressing in reducing perioperative blood loss in total knee arthroplasty. METHODS:A retrospective analysis was conducted on 90 patients who underwent total knee arthroplasty at the Honghui Hospital in Xi'an from January 2021 to December 2022.Based on the different topical use methods of tranexamic acid during surgery,patients were divided into three groups,with 30 cases in each group.In the compression dressing group,2 g of tranexamic acid was placed in the articular cavity,and after packing the wound with gauze and cotton pads,a bandage was used to compress the wound.In the periarticular injection group,2 g of tranexamic acid was injected into the surrounding tissue of the articular cavity.In the intra-articular injection group,2 g of tranexamic acid was injected into the articular cavity.The blood loss,operation time,coagulation indicators,inflammatory indicators,and postoperative complications of the three groups were statistically analyzed. RESULTS AND CONCLUSION:(1)In terms of total blood loss,hidden blood loss,and maximum hemoglobin drop,the periarticular injection group had the least amount,and there was no statistically significant difference between the compression dressing group and periarticular injection group(P>0.05).In terms of intraoperative blood loss,the compression dressing group had the least amount,and there were statistically significant differences compared with the periarticular injection group and intra-articular injection group(P<0.05).There was no statistically significant difference in operation time among the three groups(P>0.05).(2)There were no statistically significant differences in coagulation indicators(D-dimer and fibrinogen degradation products)and inflammation indicators(C-reactive protein and erythrocyte sedimentation rate)among the three groups preoperatively and on the first and third days after operation(P>0.05).(3)There was no statistically significant difference observed among the three groups in terms of slow blood flow in the affected limb,intramuscular venous thrombosis,soft tissue swelling,and incidence of wound complications(P>0.05).Additionally,no cases of deep vein thrombosis or pulmonary embolism were detected in any of the groups.(4)The topical application of tranexamic acid combined with compression dressing achieves the same effect as a periarticular injection in terms of simplicity of operation and reduced perioperative blood loss.This method also avoids the trauma caused by repeated punctures and does not increase the incidence of postoperative complications,making it a worthwhile option for clinical promotion.

AIM:To investigate the molecular mechanisms of KG-1 cell proliferation by profiling its responses to various protein kinase inhibitors.METHODS:CCK-8 assay,real time quantitative PCR(qRT-PCR)and Western-blot were used to detect the effect of various protein kinase inhibitors on KG-1 cell proliferation,the expression levels of mRNA and phosphorylation level of signaling pro-teins in the FGFR1 downstream pathways.RE-SULTS:NVP-BGJ398 and PD173074 effectively in-hibited the proliferation of KG-1 cells,indicative of a crucial role of FGFR downstream signaling.After treatment with FGFR inhibitors,the levels of p-FG-FR1OP2-FGFR1 and p-STAT5 decreased significantly(P<0.001),p-AKT decreased slightly(P<0.05),with-out affecting the p-ERK level(P>0.05).CONCLU-SION:FGFR1OP2-FGFR1 mainly acts on the down-stream STAT5 signaling pathway to promote cell proliferation.Comprehensive protein kinase inhibi-tion analysis is a reliable and direct approach to identify functional drivers of cancer cell prolifera-tion.

Type-3 innate lymphoid cell(ILC3)differentiate into lymphocyte progenitor cells and widely distributed in body,serving as a bridge between innate immunity and adaptive immunity.Previous studies believed that ILC3 was mainly involved in intesti-nal immune regulation,however,the latest studies have shown that,in addition to its role in intestinal diseases,ILC3 can also partici-pate in occurrence and development of a variety of chronic inflammatory diseases.This article reviews role of ILC3 in chronic inflamma-tory diseases.

Objective To analyze the plantar pressure distribution of knee osteoarthritis ( KOA) patients after medial opening wedge high tibial osteotomy ( MOWHTO), so as to provide biomechanical references for the surgical treatment and rehabilitation of patients. Methods A total of 31 patients with medial single compartmental KOA after unilateral MOWHTO treatment were selected as the experimental group, and 35 healthy subjects at same age were selected as the control group. The Pedomedic 40 􀅺 pressure measuring system was used to test dynamic plantar pressure. By comparing the maximum pressure ( pmax ), force-time integral ( FTI) and contact area (CA) of different plantar zones between the experimental group (operative side and unoperated side) and the control group during walking, the changes of plantar pressure in patients with medial single compartmental KOA after MOWHTO were evaluated. Results Compared with the unoperated side and the control group, the CA and FTI of the 1st metatarsal head (MH1) were higher (P<0. 05), the CA of the 4th metatarsal head (MH4)was smaller (P<0. 001), the pmax and FTI of the 5th metatarsal head (MH5) were smaller (P<0. 05), the CA of the lateral middle foot (MF-L) was smaller (P<0. 001), and the CA of the medial rear foot (RF-M) was larger (P<0. 05). Compared with the control group, the pmax of MH1 and MH2 was smaller (P<0. 05), the CA and FTI of MH5 were larger (P<0. 05), the pmax of MF-L was larger (P<0. 001), and the FTI of lateral rear foot (RF-L) was larger (P<0. 05). Conclusions Compared with healthy people, patients with medial single compartmental KOA have abnormal plantar pressure residual after MOWHTO. In clinical practice, targeted intensive rehabilitation therapy is necessary to restore the normal plantar distributions of patients.

Objective:To investigate the effect of fat mass index (FMI) on early recovery after total knee arthroplasty (TKA).Methods:Patients who underwent primary unilateral TKA in Xi'an Honghui Hospital from July 2020 to July 2021 were retrospectively analyzed. The preoperative body composition was measured by dual energy X-ray absorptiometry and the FMI was calculated. Patients were divided into normal group (male: 3.0-6.0 kg/m 2; female: 5.0-9.0 kg/m 2), overweight group (male: 6.1-9.0 kg/m 2; female: 9.1-13.0 kg/m 2), and obese group (male: >9 kg/m 2; female: >13 kg/m 2) according to level of FMI, and the operation time, blood loss, and incidence of postoperative complications were collected. Multifactorial analysis of the effect of FMI on early recovery after TKA was performed using a generalized linear model. Draw the receiver operating characteristics (ROC) curve of BMI and FMI on the predicted effect of postoperative Western Ontario and McMaster Universities (WOMAC) osteoarthritis index scores and Knee Society Score (KSS) to compare the effect of FMI with BMI on early recovery after TKA. Results:A total of 100 patients were included in the study, 24 males and 76 females, aged 65.0±8.2 years (range, 42-81 years). There were 15 cases in normal group, 55 cases in overweight group and 30 cases in obese group. All patients successfully completed the operation and were followed up for 3.15±0.72 months (range, 2.8-3.2 months). The WOMAC scores of the obese group at 2 weeks, 1 and 2 months postoperative were 34.57±3.68, 22.03±2.79, and 15.77±2.96, which were greater than those of the normal group (28.73 ±2.58, 19.07±2.71, 12.27±3.10), as well as the overweight group (30.05±4.09, 19.33±2.42, 14.84±2.42), with statistically significant differences ( P<0.05). The KSS scores of the obese group at postoperative 1 and 2 months were 68.83±5.52 and 81.17±4.49, which were lower than those of the normal group (77.33±5.63, 87.33±4.17), as well as the overweight group (72.64±5.43, 83.73 ±5.02), with statistically significant differences ( P<0.05). The WOMAC score, KSS score, and postoperative complications at 2 months postoperatively were selected as outcome indicators to plot the ROC curve, and the ROC curve for the WOMAC score at 2 months postoperatively showed an area under the curve corresponding to FMI of 0.744 (95% CI: 0.54, 0.82), which was greater than that of BMI [0.624 (95% CI: 0.51, 0.74)], and the difference was statistically significant ( Z=2.19, P=0.021). The ROC curve for the KSS score at 2 months postoperatively showed an area under the curve corresponding to FMI of 0.718 (95% CI: 0.62, 0.82), which was greater than that of BMI [0.612 (95% CI: 0.52, 0.74)], with a statistically significant difference ( Z=2.58, P=0.016). The ROC curve for postoperative complications showed an area under the curve of 0.639 (95% CI: 0.41, 0.88) for FMI and 0.605 (95% CI: 0.37, 0.84) for BMI, with no statistically significant difference ( Z=0.48, P=0.632). Conclusion:The greater the FMI the poorer the early functional recovery after initial TKA, and FMI is more valuable than BMI in predicting the early functional recovery.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

OBJECTIVE: To carried out prenatal diagnosis and genetic analysis for a case with Nail-patella syndrome. METHODS: Based on the clinical phenotype and prenatal imaging, genetic testing and prenatal diagnosis were carried out through whole exome sequencing (WES) and Sanger sequencing. RESULTS: Analysis of amniotic fluid showed that the fetus has carried a heterozygous c.139+1G>T splicing site variant [Chr9(GRCh37): g.129376868G>T] of the LMX1B gene, which was verified by Sanger sequencing. The same heterozygous variant was found in the pregnant woman, her daughter and her mother but not in her husband. Searching of HGMD database showed that the c.139+1G>T was previously unreported. CONCLUSION Nail-patella syndrome is an autosomal dominant genetic disorder with various clinical manifestations. WES is helpful for its genetic and prenatal diagnosis.
