Objective To explore the application value of stage rehabilitation intervention under the Health action process approach(HAPA)model(SRI-HAPAM)combined with tranexamic acid(TXA)in elderly patients with femoral neck fracture(FNF)undergoing total hip arthroplasty(THA).Methods Elderly FNF patients with unilateral THA in the First Affiliated Hospital of Wenzhou Medical University from December 2022 to June 2023 were enrolled.According to the random number table method,the patients were divided into routine nursing(RN)group and TXA+SRI-HAPAM group.The RN group received conventional treatment after surgery,and the TXA+SRI-HAPAM group received TXA combined with SRI-HAPAM after surgery.The bleeding indexes[hidden blood loss(HBL),explicit blood loss(EBL)and blood transfusion volume(BTV)],and the levels of hemoglobin(Hb),C-reactive protein(CRP)and D-dimer(DD)were compared between the two groups at 24 h after surgery.The hip function[joint deformity(JD),joint function(JF),joint pain(JP),joint motion(JM)and total hip function(THF)],anxiety and depression[self-rating anxiety scale and self-rating depression scale],satisfaction with care,and complications were compared between the two groups at 3 months after surgery.Results A total of 100 elderly patients with unilateral THA due to FNF were included in the study,including 54 in the TXA+SRI-HAPAM group and 46 in the RN group.Before operation,there was no significant difference in Hb,CRP,DD,JD,JF,JP,JM,THF and SAS between the two groups(P>0.05).At 24 hours after operation,Hb decreased in the two groups,while CRP and DD increased(P<0.05),and the decrease in Hb and the increase in CRP and DD,as well as HBL,EBL and BTV in the TXA+SRI-HAPAM group,were lower than those in the RN group(P<0.05).At 3 months after operation,JD,JF,JP,JM and THF in both groups increased compared with those before operation,while SAS and SDS decreased compared with those before operation(P<0.05),and the functional scores of JD,JF,JP,JM and THF in the TXA+SRI-HAPAM group were significantly higher than those in the RN group,and the scores of SAS and SDS were lower than those in the RN group(P<0.05).3 months after surgery,the nursing satisfaction of the TXA+SRI-HAPAM group was significantly higher than that of the RN group,and the total complication rate was lower than that of the RN group(P<0.05).Conclusion Compared the Routine nursing,TXA combined with SRI-HAPAM more effectively promotes postoperative recovery in patients with THA.

Objective:To explore the feasibility and effect of remote medical education model using online film reading training to improve the ability of ophthalmologists in the Xinjiang Uygur Autonomous Region (hereinafter referred to as "Xinjiang Region" ) in diagnosing fundus diseases.Methods:The three-level film reading training system of Xinjiang Production and Construction Corps system division hospital-Corps Hospital-Peking Union Medical College Hospital was established. From June 2022 to January 2023, 4 159 posterior color fundus images were continuously collected from Department of Ophthalmology of Xinjiang Corps Hospital and 4 divisional hospitals in the Corps medical system. Among them, hypertensive retinopathy, diabetic retinopathy, exudative age-related macular degeneration (AMD), atrophic AMD and retinal vein occlusion were 3 073, 651, 43, 186 and 206 cases, respectively. The images were divided into 3 rounds (first, second and last) according to the proportion of diseases. The doctors who participated in the training (hereinafter referred to as the "training") were 15 ophthalmologists from the Corps Hospital of Xinjiang Region and the division hospital of the Corps system. There were 7 male and 8 female. Age was (38.1±4.0) years. The titles of senior, deputy senior, intermediate and junior are 1, 6, 5 and 3 respectively; Bachelor's degree and master's degree are 13 and 2 respectively. The working time of fundus disease specialty was (9.6±3.3) years. The film reading system training was conducted before the first round of labeling, and after each round of film reading, the doctors of Peking Union Medical College Hospital gave feedback and explanation on the film reading results. The diagnostic consistency, sensitivity and specificity were compared by paired sample t test. Spearman or Pearson correlation analysis was conducted between the improvement of diagnostic level and professional title, education, age and working hours of ocular fundus disease. Results:All the participating doctors completed the first, second and last reading. After each round of film reading, the film reading summary was carried out for 2 hours. The average diagnostic agreement rates of participating physicians were 53.0%, 67.0% and 75.0%, respectively. The sensitivity and specificity were 0.38, 0.69, 054 and 0.66, 0.85, 0.96, respectively. There was significant difference between the first and last examination ( P<0.001). The sensitivity of the second reading was significantly higher than that of the first reading, and the sensitivity of the last reading was significantly lower than that of the second reading, with statistical significance ( P<0.05). The specificity of the second reading was significantly higher than that of the first reading, and the last reading was significantly higher than that of the second reading, with statistical significance ( P<0.05). There was no significant correlation ( P>0.05) between the improvement of diagnostic level of participating physicians and educational background ( Rho=0.07), professional title ( Rho=0.13), age ( r=0.20), and working time of ophthalmofundus disease specialty ( r=0.26). Conclusions:Relying on the three-level online telemedicine training, it can improve the ability of ophthalmologists in Xinjiang region to diagnose fundus diseases. The preliminary telemedicine education model has demonstrated potential for feasibility and effectiveness in remote areas with inadequate medical resources.

Objective:To investigate the expression of circ_0063865 in esophageal squamous cell carcinoma(ESCC)tissues and cells and its effect on the biological properties of the cells.Methods:The loop structure and stability of circ_0063865 were identified by Sanger sequencing, back-to-back primer validation and the ribonuclease R(Rnase R)tolerance assay.The expression of circ_0063865 was detected by RNA fluorescence in situ hybridization in an ESCC tissue microarray and its clinical relevance was analyzed.The expression levels of circ_0063865 in a normal esophageal epithelial cell line and ESCC cell lines were measured by real-time quantitative polymerase chain reaction(RT-qPCR). Cell counting Kit-8, the colony formation assay, the scratch assay, the transwell invasion assay and flow cytometry were used to detect the effects of circ_0063865 on cell proliferation, migration, invasion abilities and apoptosis, respectively.Results:The loop formation of circ_0063865 was verified by Sanger sequencing, back-to-back primer and Rnase R tolerance assays.The results of RNA fluorescence in situ hybridization showed that the mean fluorescence intensity of circ_0063865 expressed in ESCC tissues was significantly higher than in its paired paracancerous normal tissues( t=2.267, P<0.05). The expression of circ_0063865 was significantly associated with lymph node metastasis( χ2=4.356, P<0.05). The average overall survival time of patients with high circ_0063865 expression ESCC was lower than that of patients with low circ_0063865 expression ESCC.RT-qPCR results demonstrated that, compared with HEEC, circ_0063865 expression was elevated in ESCC cell lines( F=18.413, P<0.05). In addition, after circ_0063865 knockdown, the proliferation, migration and invasion abilities of KYSE-30 and KYSE-150 cells were significantly decreased, and the level of apoptosis was significantly increased(both P<0.05). Conclusions:The expression of circ_0063865 in ESCC is high, and changes in its expression are significantly correlated with lymph node metastasis.Additionally, circ_0063865 can promote the proliferation, migration and invasion of ESCC cells.
