BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

BACKGROUND: Blood glucose and serum albumin have been associated with cardiovascular disease prognosis, but the impact of admission-blood-glucose-to-albumin ratio (AAR) on adverse outcomes in critical ill coronary artery disease (CAD) patients was not investigated. METHODS: Patients diagnosed with CAD were non-consecutively selected from the MIMIC-IV database and categorized into quartiles based on their AAR. The primary outcome was 1-year mortality, and secondary endpoints were in-hospital mortality, acute kidney injury (AKI), and renal replacement therapy (RRT). A restricted cubic splines model and Cox proportional hazard models assessed the association between AAR and adverse outcomes in CAD patients. Kaplan-Meier survival analysis determined differences in endpoints across subgroups. RESULTS: A total of 8360 patients were included. There were 726 patients (8.7%) died in the hospital and 1944 patients (23%) died at 1 year. The incidence of AKI and RRT was 63% and 4.3%, respectively. High AAR was markedly associated with in-hospital mortality (HR = 1.587, P = 0.003), 1-year mortality (HR = 1.502, P < 0.001), AKI incidence (HR = 1.579, P < 0.001), and RRT (HR = 1.640, P < 0.016) in CAD patients in the completely adjusted Cox proportional hazard model. Kaplan-Meier survival analysis noted substantial differences in all endpoints based on AAR quartiles. Stratified analysis and interaction test demonstrated stable correlations between AAR and outcomes. CONCLUSIONS The results highlight that AAR may be a potential indicator for assessing in-hospital mortality, 1-year mortality, and adverse renal prognosis in critical CAD patients.

BACKGROUND:At present,the use of a locking bone plate combined with steel wire or steel cable for the treatment of periprosthetic femoral fracture often adopts monocortical fixation,which is not stable and the proximal end of the bone cannot be achieved anatomically fitted by plate.The customized anatomical plate system can effectively solve this problem. OBJECTIVE:To explore the biomechanical strength of a customized anatomical plate system in fixation of Vancouver BI periprosthetic femoral fracture. METHODS:CT thin layer scanning data of normal femurs of 1 006 cases were selected and input into the MIMICS 21.0 software to establish the three-dimensional reconstruction model of the femur,which was set as the three-dimensional reconstruction group.56 complete human femoral specimens were selected as the femoral specimen group.The measured results of the two groups for femoral anatomical appearance were compared.If there was no significant difference between the two groups,the approximate appearance of a customized anatomical plate system was designed based on the measurement results in MIMICS 21.0 software and NX11.0 software.The customized anatomical plate system was designed and prepared according to the above measurement results.Eight pairs of frozen human femurs were selected to make Vancouver BI periprosthetic femoral fracture,which of the left were thin layer scanned by dual-source CT to obtain data.The data were transferred to determine the customized anatomical plate system model by the above design software.Eight sets of customized anatomical plate systems were ultimately produced,relying on the instrument company.The eight pairs of models were numbered 1-8.The left side was fixed with the customized anatomical plate system(customized anatomical plate system group);the right side was fixed with a metal locking plate system-large locking plate(claw plate group).L1-L4 and R1-R4 were subjected to vertical short-cycle loading test and vertical loading test.L5-L8 and R5-R8 were subjected to horizontal short-cycle loading test and four-point bending test.The vertical loading test and four-point bending test were used to collect bending load,bending displacement,and bending strain.Two short cycle loading tests were used to collect strain displacement to compare the maximum load,maximum displacement,bending stiffness,and short-period displacement resistance of the two kinds of bone plates. RESULTS AND CONCLUSION:(1)There were no significant differences in all indexes between the three-dimensional reconstruction group and the femoral specimen group(P>0.05).Individual customized anatomical plate system was designed based on the measurement results combined with digital software.(2)In the vertical loading test,the maximum load was higher(P=0.015),the maximum bending displacement was smaller(P=0.014),and the bending stiffness was higher(P=0.005)in the customized anatomical plate system group compared with the claw plate group.(3)In the four-point bending test,the maximum load was higher(P=0.023),the bending stiffness was higher(P=0.005),and the maximum bending displacement was not significant(P=0.216>0.05)in the customized anatomical plate system group compared with the claw plate group.(4)In the vertical short-cycle loading test,the average level of bending displacement in the customized anatomical plate system group(0.23±0.10 mm)was significantly lower than that in the claw plate group(0.44±0.02 mm)(P<0.05).(5)There was no significant difference in the average level of bending displacement between the two groups in the horizontal short cycle loading test(P>0.05).(6)It is concluded that the customized anatomical plate system has personalized anatomical characteristics,and the fixation of Vancouver BI periprosthetic femoral fracture is more stable,which has certain significance for clinical treatment.

Objective To explore the clinical efficacy and safety of calcium dobesilate capsules combined with conbercept in the treatment of diabetic retinopathy with macular edema.Methods Patients with diabetic retinopathy complicated with macular edema were divided into control group and treatment group by cohort method.The control group was given intravitreal injection of conbercept ophthalmic injection 50 μL every time once a month.On the basis of the treatment in the control group,the treatment group was orally treated with calcium dobesilate capsules 0.5 g three times a day.Both groups were treated for 3 months.The efficacy after treatment,and ocular recovery indexes[best corrected visual acuity(BCVA),central macular thickness(CMT)],aqueous humor pro-angiogenic factors[vascular endothelial growth factor(VEGF),stromal cell-derived factor 1(SDF-1)]and aqueous humor hypoxic response factors[erythropoietin(EPO),hypoxia-inducible factor-1 α(HIF-1α)]were compared between two groups,and the safety of the two groups was evaluated.Results The treatment group and the control group were included in 48 cases and 56 cases,respectively.After 3 months of treatment,the total effective rates of the treatment group and the control group were 92.86％(52 cases/56 cases)and 79.17％(38 cases/48 cases),and the difference was statistically significant(P＜0.05).After 3 months of treatment,the BCVA of the treatment group and the control group were(0.58±0.14)and(0.45±0.12)logMAR,respectively;the CMT were(281.22±37.68)and(329.52±46.74)μm,respectively;the expression of VEGF in aqueous humor were(141.56±22.49)and(164.22±32.51)ng·L-1,respectively;the expression of EPO in aqueous humor were(8.03±2.72)and(9.69±3.11)mU·mL-1,respectively;the expression levels of HIF-1α in aqueous humor were(168.18±69.52)and(221.47±72.46)mg·L-1,respectively;the expression levels of SDF-1 in aqueous humor were(465.32±76.28)and(526.82±94.43)mg·L-1,respectively.The above indexes in the treatment group were significantly different from those in the control group(all P＜0.05).The adverse drug reactions in the treatment group and the control group mainly included transient elevated intraocular pressure,vitreous hemorrhage,and gastrointestinal reactions.The incidence of adverse drug reactions in the treatment group and the control group were 14.29％(8 cases/56 cases)and 12.50％(6 cases/48 cases),respectively.There was no statistically significant difference(P＞0.05).Conclusion Calcium dobesilate capsules combined with conbercept ophthalmic injection has an exact efficacy in the treatment of diabetic retinopathy with macular edema.It has obvious advantages in improving visual acuity and fundus microcirculation,and has good safety.

Objective:To evaluate the objective response rate (ORR) of induction chemoimmunotherapy with camrelizumab plus TPF (docetaxel, cisplatin, and capecitabine) for locally advanced hypopharyngeal squamous cell carcinoma (LA HSCC) and potential predictive factors for ORR.Methods:A single-center, prospective, phase 2 and single-arm trial was conducted for evaluating antitumor activity of camrelizumab+TPF(docetaxel+cisplatin+capecitabine) for LA HSCC between May 21, 2021 and April 15, 2023, patients admitted to the Eye & ENT Hospital affiliated with Fudan University. The primary endpoint was ORR, and enrolled patients with LA HSCC at T3-4N0-3M0 received induction chemoimmunotherapy for three cycles: camrelizumab 200 mg day 1, docetaxel 75 mg/m 2 day 1, cisplatin 25 mg/m 2 days 1-3, and capecitabine 800 mg/m 2 days 1-14. Patients were assigned to radioimmunotherapy when they had complete response or partial response (PR)>70% (Group A), or assigned to surgery plus adjuvant radiotherapy/chemoradiotherapy when they had PR≤70% (Group B), and the responses were defined by using tumor volume evaluation system. Tumor diameter was also used to assess the treatment responses by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Use SPSS 23.0 software was used to analyze the data. Results:A total of 51 patients were enrolled who underwent the induced chemoimmunotherapy for three cycles, and all were males, aged 35-69 years old. After three cycles of induction immunochemotherapy, 42 (82.4%) patients existed in Group A (complete response or PR>70%) and 9 patients (17.6%) in Group B (PR≤70%), the ORR was 82.4%. The primary endpoint achieved expected main research objectives. Compared to the patients of Group A, the patients of Group B showed the higher T stage and the larger volume of primary tumor before induced immunochemotherapy, and also had the less regression of tumor volume after induced immunochemotherapy (all P<0.05). The optimal cutoff value of pre-treatment tumor volume for predicting ORR was 39 cm 3. The T stage ( OR=12.71, 95% CI: 1.4-112.5, P=0.022) and the volume ( OR=7.1, 95% CI: 1.4-36.8, P=0.018) of primary tumor were the two main factors affecting ORR rate of induction chemoimmunotherapy. Conclusion:The induction chemoimmunotherapy with camrelizumab plus TPF shows an encouraging antitumor efficacy in LA HSCC.

Objective:To investigate the postoperative prosthesis position and early clinical efficacy of 3D printing patient-specific instrumentation (PSI)-assisted unicompartmental knee arthroplasty (UKA).Methods:The clinical data of 15 patients (17 knees, PSI group) with medial compartment knee osteoarthritis who underwent PSI-assisted UKA in the Second Affiliated Hospital, the Air Force Medical University from May to August 2023 were retrospectively analyzed, matched with fifteen patients (17 knees, non-PSI group) with medial compartment knee osteoarthritis undergoing conventional UKA. The differences in the prosthesis placement positions in the postoperative X-ray films between the two groups were compared, including the coronal varus-valgus angles of the tibial and femoral prostheses, the sagittal posterior inclination angle of the tibial prosthesis, the flexion-extension angle of the femoral prosthesis, and the height of the reconstructed joint line. The indicators related to the lower limb alignment (including the femoral valgus angle, the lateral femoral angle, the hip-knee-ankle angle, and the femur-tibia angle) and the range of motion of the knee joint before and after the operation were compared. The Oxford knee score (OKS), American Knee Society (AKS) knee score and function score, and the visual analogue scale (VAS) were used to evaluate the clinical effects of the two groups.Results:In the PSI group, the coronal varus-valgus angle of the tibial prosthesis was 1.6°±0.3° after the operation, and the sagittal posterior inclination angle was 5.7°±0.8°. The coronal varus-valgus angle of the femoral prosthesis was -0.5°±1.5°, and the sagittal flexion-extension angle was 4.0°±1.9°. In the non-PSI group, the corresponding angles were 2.3°±0.6°, 4.5°±1.0°, 1.4°±1.5°, and 7.3°±2.2° respectively with significant differences between the two groups ( P<0.05). The OKS of the PSI group before and after the operation were 26.5±1.8 and 38.6±4.1 points respectively. The AKS knee score were 56.9±8.6 and 89.2±7.2 points. The AKS function score were 70.1±4.2 and 77.5±9.4 points. The VAS were 4.5±3.7 and 2.3±0.3 points, and the range of motion of the knee joint were 115.2°±4.8° and 125.9°±4.6° with significant differences ( P<0.05). The OKS of the non-PSI group before and after the operation were 25.3±6.2 and 38.2±3.5 points respectively. The AKS knee score were 50.6±9.3 and 84.5±6.6 points. The AKS function score were 73.4±3.9 and 77.2±4.8 points. The VAS were 5.8±2.4 and 2.5±1.6 points, and the range of motion of the knee joint were 113.6°±6.7° and 122.3°±5.0° with significant differences ( P<0.05). There were inter-group differences in the AKS knee score and the range of motion of the knee joint after the operation between the two groups with significant differences ( P<0.05). Conclusion:PSI guides-assisted UKA can effectively correct the lower limb alignment of patients and improve knee joint function with good short-term efficacy. Compared with conventional UKA, PSI guides-assisted UKA is less time-consuming with higher precision in prosthesis installation position and fewer post-operative complications.

Objective: The effect on fat infiltration (FI) of paraspinal muscles in degenerative lumbar spinal diseases has been demonstrated except for spinopelvic parameters. The present study is to identify the effect of spinopelvic parameters on FI of paraspinal muscle (PSM) and psoas major muscle (PMM) in patients with degenerative lumbar spondylolisthesis. Methods: A single-center, retrospective cross-sectional study of 160 patients with degenerative lumbar spondylolisthesis (DLS) and lumbar stenosis (LSS) who had lateral full-spine x-ray and lumbar spine magnetic resonance imaging was conducted. PSM and PMM FIs were defined as the ratio of fat to its muscle cross-sectional area. The FIs were compared among patients with different pelvic tilt (PT) and pelvic incidence (PI), respectively. Results: The PSM FI correlated significantly with pelvic parameters in DLS patients, but not in LSS patients. The PSM FI in pelvic retroversion (PT > 25°) was 0.54 ± 0.13, which was significantly higher in DLS patients than in normal pelvis (0.41 ± 0.14) and pelvic anteversion (PT < 5°) (0.34 ± 0.12). The PSM FI of DLS patients with large PI ( > 60°) was 0.50 ± 0.13, which was higher than those with small ( < 45°) and normal PI (0.37 ± 0.11 and 0.36 ± 0.13). However, the PSM FI of LSS patients didn’t change significantly with PT or PI. Moreover, the PMM FI was about 0.10–0.15, which was significantly lower than the PSM FI, and changed with PT and PI in a similar way of PSM FI with much less in magnitude. Conclusion FI of the PSMs increased with greater pelvic retroversion or larger pelvic incidence in DLS patients, but not in LSS patients.
