Objective To compare and analyze the early- to mid-term outcomes of transcatheter aortic valve replacement (TAVR) combined with percutaneous coronary intervention (PCI) versus surgical aortic valve replacement (SAVR) combined with coronary artery bypass grafting (CABG) for the treatment of significant aortic stenosis (AS) and coronary artery disease (CAD). Methods The data of patients with significant AS and CAD who underwent surgical treatment at Central China Fuwai Hospital of Zhengzhou University from January 2018 to July 2023 were collected. These patients were divided into a TAVR+PCI group and a SAVR+CABG group according to the operation method. Propensity score matching (PSM) was used to select patients with close clinical baseline characteristics, and the early- to mid-term outcomes of the two groups were compared. Results A total of 272 patients were enrolled, including 208 males and 64 females, with a mean age of (64.16±8.24) years. There were 47 patients in the TAVR+PCI group and 225 patients in the SAVR+CABG group. After 1 : 1 PSM, 32 pairs were selected. There was no statistical difference in baseline data between the two groups (P>0.05). Compared with the SAVR+CABG group, the TAVR+PCI group had significantly shorter operative time, mechanical ventilation time, ICU stay, postoperative hospital stay, and less intraoperative bleeding, and significantly lower postoperative transfusion and complete revascularization rates (P<0.05). The differences in the rates of postoperative in-hospital death, myocardial infarction, stroke, or other complications between the two groups were not statistically significant (P>0.05), and the differences in the rates of moderate-to-severe perivalvular leakage, death, or readmission in the mid-term follow-up were not statistically significant (P>0.05). Conclusion In patients with significant AS and CAD, the early- and mid-term rates of death and complications are similar between those treated with TAVR+PCI and SAVR+CABG, and TAVR+PCI is a safe alternative to SAVR+CABG.

Objective To understand the internal quality control(IQC)situation of routine biochemical projects in Guizhou Province from 2020 to 2022,and to use the analysis batch length sigma rule to select the appropriate IQC strategy for routine biochemical projects.Methods A sum of 41,41 and 52 laboratories were selected from the laboratories participating in the first external quality assessment(EQA)program of the routine biochemical project in the Guizhou Provincial Center for Clinical Laboratory from 2020 to 2022,which uniformly used two concentration levels of internal quality control products produced by Randox Company in the UK.The coefficient of variation(CV)was calculated based on their IQC information,and then these CV values were used to compare with imprecise performance specifications such as WS/T403-2012 standards.The IQC situation of routine biochemical projects of Guizhou Province in recent years was analyzed.Randomly 15 laboratories were selected each year to report the results of the triglyceride project,and their σ values were calculated.Based on the Westgard sigma rule flowcharts of the analysis batch length,appropriate quality control strategies were selected and the quality goal index(QGI)was calculated to evaluate analytical performance of laboratory detection system.Results In the current monthly CV,the proportion of laboratories that met the WS/T403-2012 standards for Ca and TP projects was relatively low,while the pass rates for 7 projects(P,CK,LDH and other projects)were all above 80%,showing an increasing trend year by year.The proportion of laboratories with the 7 projects(P,CK,LDH and other projects)meeting the performance specifications for biomedical variation(appropriate)all reached 90%,while the proportion of laboratories with 5 projects(Na,Ca,Cl and other projects)was relatively low.The proportion of 10 projects such as P,CK,and LDH in cumulative CV of laboratories that met the performance specifications for biomedical variation(appropriate)was over 90%.For the triglyceride project,from 2020 to 2022,there were 2,5 and 13 laboratories that reached 6 σ horizontal.Compared to values of 2020 and 2021 years,the trend of σ values changes of 2022 was increasing(t=3.855,3.511,P≤0.001),indicating that the analytical performance of these laboratories was getting better and better.Conclusion The IQC levels of routine biochemical projects in Guizhou Province were increasing year by year.The Westgard sigma rule of the analysis batch length is designed with personalized quality control rules for various laboratories in Guizhou Province,thus improving laboratory testing capabilities and better severing clinics.

Objective:To determine the effects of early enteral nutrition (EEN) on the short-term prognosis of patients receiving veno-arterial extracorporeal membrane oxygenation (VA-ECMO).Methods:61 patients admitted to the Coronary Care Unit (CCU) of Henan Provincial Peoples' Hospital from February 2022 to March 2023 to receive VA-ECMO treatment were selected as the study objects according a retrospective survey. The patients were divided into an achievement group ( n=34) and a non-achievement group ( n=27) based on whether the feeding amount reached 70% or over of the target calories (25kcal/kg.d) on the 7th day of ECMO treatment. The general characteristics, disease information, complications, and prognosis between the two groups after ICU admission were recorded and compared. A multivariable Cox proportional hazards model was used to evaluate the impact of various factors on clinical outcomes. Kaplan-Meier analysis was used to draw survival curves for the two groups, and the predictive value of the ratio of actual EN intake to target energy was calculated by plotting the ROC curve. Results:A total of 61 patients were included, with an overall in-hospital mortality rate of 50.82% (31/61), with 32.35% (11/34) in the achievement group, and 70.37% (19/27) in the non-achievement group. Cox regression analysis revealed that the occurrence of hypoxic-ischemic encephalopathy (HR=0.341, 95% CI:0.119-0.975), ECOM weaning failure ( HR=0.269, 95% CI:0.111-0.651), and achieving EN targets on the 7th day of VA-ECMO treatment ( HR=10.891, 95% CI:1.178-100.718) were independent factors for patient mortality during hospitalization. The ROC curve for the percentage of EN achievement on the 7th day of VA-ECMO treatment and in-hospital mortality showed an area under the curve of 0.755, with a cutoff value of 0.73. Conclusion:The presence of ischemic hypoxic encephalopathy, ECOM weaning failure, and whether achieving EN targets or not is closely related to the prognosis of VA-ECMO patients. Patients who achieving EN targets of over 73% had the lowest in-hospital mortality rate. Therefore, more attention should be paid to the energy intake of VA-ECMO patients to reduce their risk of mortality.

Objective:To summarize the strategy and method for the treatment of critically ill patients with self-made extracorporeal membrane oxygenation (ECMO) system.Methods:A observative study was conducted. Fifty-six patients with ECMO assisted support in Fuwai Central China Cardiovascular Disease Hospital from December 2020 to December 2021 were enrolled. According to the clinical situation of the patients and the wishes of the family, conventional ECMO package (conventional group) or self-made ECMO package (self-made group) was chosen. In the conventional group, the disposable ECMO package was used to install the machine, pre charge and exhaust the air. In the self-made group, the disposable consumables commonly used in extracorporeal circulation during cardiac surgery (including centrifugal pump heads, membrane oxygenation, tubes, connectors, etc.) were used to create a self-made ECMO system. Based on the patient's situation, personalized tube model selection and length control were carried out. The preparation time, auxiliary time, auxiliary method, total pre charge volume, free hemoglobin (FHb) levels after 2 hours of ECMO operation and operating costs, as well as changes in hemodynamics, arterial blood gas analysis, and blood indicators within 48 hours after ECMO placement in the two groups were recorded. The occurrence of adverse events related to the ECMO system during ECMO adjuvant therapy in two groups was simultaneously observed.Results:Fifty-six patients were enrolled finally, with 28 cases in the conventional group and 28 cases in the self-made group, and all successfully completed the operation of ECMO. There was no statistically significant difference in ECMO system preparation time, auxiliary time, auxiliary method, and FHb levels after 2 hours of ECMO operation between the conventional group and the self-made group [preparation time (minutes): 13±4 vs. 15±5, auxiliary time (hours): 287±34 vs. 276±42, veno-arterial ECMO (cases): 22 vs. 24, veno-venous ECMO (cases): 6 vs. 4, FHb after 2 hours of ECMO operation (mg/L): 226±67 vs. 253±78, all P > 0.05]. However, the total pre charge volume and operating costs in the self-made group were significantly lower than those in the conventional group [total pre charge volume (mL): 420±25 vs. 650±10, operating costs (ten thousand yuan): 3.8±0.4 vs. 6.7±0.3, both P < 0.01]. The hemodynamics, arterial blood gas analysis, and blood indicators of patients in the two groups were relatively stable within 48 hours after ECMO operation, and most of the indicators between the two groups showed no statistically significant differences. The hemoglobin (Hb) levels at 12, 24, and 48 hours after the machine transfer in the self-made group were significantly higher than those in the conventional group (g/L: 128.5±23.7 vs. 117.5±24.3 at 12 hours, 121.3±31.3 vs. 109.6±33.2 at 24 hours, 118.5±20.1 vs. 105.2±25.7 at 48 hours, all P < 0.05). Both groups of patients did not experience any adverse event related to the ECMO system, such as membrane pulmonary infiltration, joint detachment, and massive hemolysis, during the ECMO assisted treatment process. Conclusion:When implementing ECMO for critically ill patients in clinical practice, a self-made ECMO system with disposable consumables commonly used in extracorporeal circulation during cardiac surgery can be used for cardiopulmonary function assistance support, thereby saving patients medical costs and alleviating their dependence on disposable ECMO package in clinical practice.

Objective:To evaluate the effectiveness,safety and economics of absorbable drug-eluting coronary stent systems using rapid health technology assessment tools,and to provide evidence-based basis for rational use for clinicians use and expert evaluation.Methods:A computer search was performed on PubMed,CNKI,Wanfang,VIP and other databases from 1 January 2014 to 1 January 2023 for relevant literature on patients with coronary artery disease who were treated with coronary artery stent interventional surgery.The 210 collected literatures were screened and extracted according to the inclusion and exclusion criteria,and the literature quality evaluation was carried out.The extracted data related to the intravascular thrombosis rate,myocardial infarction rate,cardiac mortality rate,all-cause mortality rate,target lesion revascularization rate and intravascular adverse event incidence of absorbable drug-eluting coronary stents and drug-eluting coronary stents were meta-analyzed by Revman5.4 software.Results:7 studies were ultimately included in the comparative study of absorbable drug-eluting coronary stents and drug-eluting coronary stents.The thrombosis rate,all-cause mortality rate and intravascular adverse event rate of absorbable drug-eluting coronary stents were lower than those of drug-eluting coronary stents,and the difference was statistically significant(Z=2.16,1.89,2.22,P＜0.05).There were no statistically significant difference in the myocardial infarction rate,cardiac mortality rate and target lesion revascularization rate between absorbable drug-eluting coronary stents and drug-eluting coronary stents(P＞0.05).Conclusion:There was no significant difference in safety and efficacy between absorbable drug-eluting coronary stents and drug-eluting coronary stents.In terms of economy,the cost of absorbable drug-eluting coronary stents is significantly higher than that of drug-eluting coronary stents,and patients can choose stents according to their own economic conditions and other actual conditions.

Objective Discuss the application methods and effects of closed femoro-femoral partial bypass(C-FPB)in thoracoabdominal aortic replacement(TAAAR)surgery.Methods A retrospective analysis of the clinical data of 70 cases of TAAAR assisted by C-FPB from April 2021 to May 2023,some of which combined with abdominal organ perfusion.The main evaluation indicators were in-hospital mortality,postoperative stroke,postop-erative spinal cord injury,and the incidence of hemodialysis.Based on an open-type conventional Cardiopulmonary bypass(CPB)circuit,the venous tubing was split with a 10×10×10 mm"Y"connector directly connected to the inlet of the centrifugal pump,and the tubing after the roller pump was connected to the outlet of the centrifugal pump,while the front of the membrane oxygenator with another 10×10×10 mm"Y"connector to establish a closed femoro-femoral bypass.During bypass,the lower body is perfused by the centrifugal pump,while the upper body is perfused by the roller pump.Results No system failures happen in all cases.The average bypass time was(101.0±22.2)minutes,the average time for intercostal artery reconstruction was(18.6±5.4)minutes,with an average of(4.7±1.8)pairs.The average length of stay in the ICU was(5.1±1.5)days,and the average length of hospital stay was(34.4±12.5)days.2 cases(2.9%)experienced postoperative stroke,1 case(1.4%)resulted in in-hospital mortality,2 cases(2.9%)experienced postoperative paraplegia,7 cases(10.0%)underwent postop-erative hemodialysis,and 3 cases(4.3%)experienced prolonged mechanical ventilation.Conclusion The Closed-type femoro-femoral partial bypass takes the whole surgical process into account,reduces the management difficulty for perfusionist,and provides a unique advantage for distal perfusion during thoracoabdominal aortic replacement surgery.

Objective:To compare the outcomes between the patients of peroneal tendon dislocation treated by either total endoscopic surgery with preferential incision of the tendon sheath or traditional open surgery.Methods:This is a retrospective cohort study. The clinical data of 45 patients with peroneal tendon dislocation were operated at the Department of Sports Medicine and Joint Surgery, Nanjing First Hospital from July 2016 to June 2020. There were 26 males and 19 females,aged (31.2±9.3) years (range: 17 to 45 years). Among them,23 patients underwent open peroneal tendon groove deepening followed by tendon sheath repair(traditional open group), and the other 22 patients underwent similar operations but all-endoscopically with preferential incision of peroneal tendon sheath(total endoscopic group). The perioperative data of patients were collected, and pain visual analogue score (VAS) was used to evaluate the pain changes before and after surgery and during the follow-up period, and the American Orthopaedic Foot and Ankle Society ankle hindfoot scale (AOFAS-AH), range of motion (ROM), the MOS item short form health survey (SF)-36, and the homemade questionnaire of patient satisfaction were used to evaluate the patients′ outcomes after the operation, and CT scan was carried out to observe the deepening of the fibular groove and MRI to observe the status of the peroneal tendon and sheath during the follow-up. Independent sample t test, Wilcoxon rank sum test were used for comparison of quantitative data between groups. Chi-square test,Mann-whitney U or Fisher exact test was used for comparison of classified data, respectively;repeated measure ANOVA and paired sample t test were used for comparison of quantitative data before and after surgery in groups. Results:There was no statistically significant difference between the two groups of patients in terms of gender, age, disease duration, side of injury, and injury typing (all P>0.05). There was no significant difference between the two groups in terms of operation time ((47.9±5.4)minutes vs. (47.2±6.3)minutes; t=0.402, P=0.690), but the incision length ((2.17±0.35)cm vs.(5.97±0.42)cm; t=32.892, P<0.01) and hospitalization time ((4.0±1.7)days vs. (7.6±3.6)days; t=4.249, P<0.01) were significantly shorter in the total endoscopic group than those in the traditional open group. All patients were followed up for more than 12 months, and the follow-up time was (19.2±3.9) months (range: 12 to 24 months). The total endoscopic group showed a significant increase in VAS, AOFAS-AH, SF-36 score and patient satisfaction rate at 3 months postoperatively and the last follow-up (all P<0.05). Three months after surgery, the ROM in the total endoscope group was higher than that in the traditional group ((62.14±1.46) ° vs. (53.13±1.52) °; t=20.315, P<0.01), and there was no significant difference between the two groups at the last follow-up ((63.18±1.10) ° vs. (63.48±2.43) °; t=0.531, P=0.599). The imaging examination results showed that the situation of fibular groove deepening in the total endoscopic group was better than that in the traditional open group. Conclusion:Total endoscopic surgery with preferential incision of the tendon sheath has the advantages of minimally invasivenessas compared with traditional open surgery with faster recovery and better outcome.

Objective:To investigate the clinical efficacy of simultaneous arthroscopic repair of anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) for treating chronic lateral ankle instability (CLAI) in conjunction with subtalar instability (STI).Methods:This is a retrospective case series study. The clinical data of 15 patients with ankle arthroscopic in the Department of Hand and Foot Surgery, the Second Affiliated Hospital of Soochow University from January 2019 to December 2022 were analyzed retrospectively. There were 11 male cases and 4 female cases, aged (28.6±1.5) years (range: 19 to 39 years). All the patients were evaluated by manual inversion stress X-ray and MRI before operation. Arthroscopically observing and then repairing the ATFL and CFL separately after further diagnostic confirmation. One year after operation, MRI was performed, and pain visual analogue score(VAS), American Orthopedic Foot and Ankle Society ankle hindfoot scale (AOFAS-AH) and Karlsson ankle functional scale(KAFS) were evaluated. Data were compared using paired sample t test. Results:The follow-up period was (23.6±2.3) months (range: 12 to 30 months). At last follow-up,the VAS decreased from 6.1±1.4 preoperatively to 1.4±1.2( t=9.482, P<0.01).The AOFAS-AH improved from 50.5±11.7 preoperatively to 94.2±6.1( t=-13.132, P<0.01), and the KAFS improved from preoperatively 44.3±10.8 to 90.8±6.4 ( t=-12.510, P<0.01). There was no complication such as recurred instability or joint stiffness. Conclusions:Arthroscopically repairing the ATFL and CFL separately can effectively restore the stability of the ankle and subtalar joint with small trauma. Patients can recover quickly after surgery. It provides a new idea for the clinical treatment of CLAI combined with STI.
