ABSTRACT

Objective:To analyze the effect of patellar tilt angle on postoperative outcomes after total knee arthroplasty (TKA) without patella resurfacing.Methods:A total of 143 patients with end-stage knee osteoarthritis who underwent TKA without patellar replacement in the First Affiliated Hospital of Nanjing Medical University from October 2020 to October 2021 were retrospectively analyzed. There were 32 males and 111 females, aged 68.44±6.79 years (range, 52-86 years). Patients were divided into three groups according to the postoperative patellar tilt angle: tilt angle<5° was the mild tilt group (97 cases), 5°≤tilt angle<10° was the moderate tilt group (31 cases), and tilt angle≥10° was the severe tilt group (15 cases). All patients were followed up in the outpatient clinic at 3, 6 and 12 months after surgery, and knee visual analogue score (VAS), Hospital for Special Surgery (HSS) score and patella Feller score were observed and recorded to compare the postoperative knee pain and function of patients in different patella tilt groups.Results:All patients were followed up for 1.16±0.23 years (range, 1.0-2.0 years). There was no significant difference in baseline data between the groups. There were significant differences in the intra-group comparison of the VAS score before and after surgery among the three groups ( F=51.12, P<0.001; F=36.90, P<0.001; F=15.76, P<0.001). The VAS scores at 3, 6 and 12 months after operation were significantly lower than those before operation ( P<0.05). The knee VAS of the severe group was higher than that of the mild and moderate groups at 3, 6 and 12 months after surgery, and the difference was statistically significant ( P<0.05). There were statistically significant differences in knee HSS scores before and after surgery among the three groups ( F=81.12, P<0.001; F=36.05, P<0.001; F=32.93, P<0.001). The knee HSS scores at 3, 6 and 12 months after surgery were higher than those before surgery, and the difference was statistically significant ( P<0.05). The knee HSS scores of the severe tilt group at 3, 6 and 12 months after surgery were lower than those of the mild and moderate groups, and the difference was statistically significant ( P<0.05). There were statistically significant differences in the intra-group comparison of the patella Feller score before and after surgery among the three groups ( F=88.81, P<0.001; F=49.59, P<0.001; F=37.40, P<0.001). The patellar Feller score at 3, 6 and 12 months after surgery was higher than that before surgery, and the difference was statistically significant ( P<0.05). The patellar Feller score of the severe group at 3, 6 and 12 months after surgery was lower than that of the mild and moderate groups, and the difference was statistically significant ( P<0.05). Conclusion:Patellar tilt angle after TKA without patellar resurfacing will increase knee pain and limit joint function.

ABSTRACT

OBJECTIVES@#To establish an electrophysiological model of alcoholic cardiomyopathy by inducing pluripotent stem cells (iPSCs) to differentiate into cardiomyocytes (iPSC-CM) in vitro.@*METHODS@#The human iPSC were expanded in vitro and differentiated into iPSC-CM. The iPSC-CM were divided into a blank control group, an alcoholic experiment group (according to the concentration of alcoholic, the alcoholic experiment was also divided into many subgroups), and a KN93 treatment group. Then the efficiency of iPSC differentiated to iPSC-CM was detected by immunofluorescence, the function of iPSC-CM was detected by cell counting kit-8 (CCK8) assay and lactate dehydrogenase (LDH) activity assay kit. The electrophysiological activity of iPSC-CM was monitored by real time cellular analysis (RTCA), the injury of iPSC-CM caused by alcohol was further verified by the mitochondrial membrane potential fluorescence probe JC-1 staining combined with RTCA analysis.@*RESULTS@#Compared with the blank control group, the different doses (25, 50, 100, 150, 200, 250, 300 mmol/L) of alcohol could significantly inhibit the proliferation of iPSC-CM in a dose-dependent manner (all <0.05). Compared with the blank control group, the activity of iPSC-CM was significantly reduced by 100 mmol/L alcohol, resulting in the increase of LDH release, the decrease of mitochondrial membrane potential, the amplitude and beating rate (all <0.05). Compared with the 100 mg/mL alcoholic experiment group, the KN93 treatment group significantly alleviated the damage of alcohol to iPSC-CM by blocking the necrotic apoptotic pathway, resulting in the decrease of LDH release, the increase of mitochondrial membrane potential, the amplitude and beating rate (all <0.05).@*CONCLUSIONS@#The electrophysiological model of alcoholic cardiomyopathy based on the differentiation of cardiomyocytes are successfully established, which can be used to study the electrophysiological activity and the molecular mechanism for relevant diseases, and it may provide a more reasonable and effective research tool for drug screening and clinical study.

ABSTRACT

Objective@#To compare the consistency and accuracy of using 2 criteria for decision making of aspirin use for the primary prevention of ischemic cardiovascular disease (ISCVD) and explore the current status and related factors of aspirin use for the primary prevention of ISCVD in Chinese outpatients.@*Methods@#This cross-sectional study enrolled 3 018 outpatients with hypertension, diabetes, or hypercholesterolemia, who visited the General Practice (GP) clinics of Anzhen hospital in Beijing from September to December 2015 were enrolled in. The information of risk factors for ISCVD and use of aspirin was collected. Both quantitative and qualitative criteria were used to make the decision of aspirin use for primary prevention of ISCVD in this patient cohort. Quantitative criteria were derived from the 2011 Chinese guideline of cardiovascular disease prevention: aspirin use for primary cardiovascular disease prevention in population with risk of ISCVD in the next 10 years≥10%. Qualitative criteria were derived from the Chinese expert consensus on the aspirin use issued in 2013: aspirin should be given for the purpose of primary ISCVD in population with≥3 risk factors:(1) men aged ≥50 years or postmenopausal women; (2) hypertensive subjects with blood pressure ≤150/90 mmHg(1 mmHg=0.133 kPa);(3) diabetes; (4) hypocholesteremia; (5) obesity with body mass index (BMI)≥28 kg/m2; (6) Smokers;(7) with familiar premature ISCVD history (male<55 years, female<65 years). Demographic data of participants were obtained by questionnaire, on-site measurements or screening previous medical records.@*Results@#67.1% participants (n=2 024) should be recommended to take aspirin as primary prevention medication using 10-year risk of ISCVD≥10% as the criteria, and 77.9% participants (n=2 350) should be recommended to take aspirin as primary prevention medication using number of risk factors≥3 as the criteria. With 10-year risk of ISCVD≥10% as the gold standard and risk factors≥3 as the evaluation criteria, the sensitivity was 97%, specificity was 61%, the consistency rate was 85%, Kappa value was 0.628 (U=35.824, P<0.001) , indicating that the consistency of the 2 criteria was good. The percentage of real-world aspirin use for primary prevention of ISCVD in this cohort was significantly higher for participants evaluated with the 10-year risk of ISCVD≥10% than that evaluated with 3 risk factors (53.1% vs. 49.2%, χ2=6.523, P=0.011). 12.7% participants with 10-year risk of ISCVD<10% and 6.6% participants with<3 risk factors took aspirin for the primary prevention of ISCVD in this cohort. Age, smoking, hypertension, diabetes and hypercholesterolemia were significantly related to the aspirin use in this cohort, relative ORs were 1.047 (95%CI 1.035-1.060) , 1.969 (95%CI 1.403-2.762) , 2.065 (95%CI 1.623-3.629) , 3.493 (95%CI 2.726-4.475, and 1.344 (95%CI 1.109-1.628) , respectively. Obesity and familial history of premature ISCVD were not related to the aspirin use, relative ORs were 1.137 (95%CI 0.828-1.562) and 0.986 (95%CI 0.767-1.266) .@*Conclusions@#The consistency of the 2 criteria for decision making of aspirin use for the primary prevention of ISCVD is good and about 50% participants who should be recommended to the use of aspirin for the primary prevention of ISCVD took the aspirin in the real-world scenario. The use of aspirin as primary prevention strategy for ISCVD in the real-world scenario is related to age, smoking, hypertension, diabetes and hypercholesterolemia.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the impact of pre-primary percutaneous coronary intervention (PCI) β blocker use on the development of no-reflow in ST-segment elevation myocardial infarction (STEMI) patients post PCI.</p><p><b>METHODS</b>We retrospectively evaluated 1 615 outpatients with STEMI who underwent primary primary PCI with in 12 hours from symptom onset admitted to Beijing Anzhen Hospital and Chinese people's liberation army general hospital from January 2007 to June 2011. The study population was divided into the following 2 groups: β blocker group (pretreatment with β blockers ≥ one month before admission, n = 257) and non-β blockers group (pretreatment with β blockers < one month before admission or had no β blocker, n = 1 358). No-reflow was defined as TIMI grade < 3 in last imaging of coronary artery after stenting. Multivariable logistic regression analyses were used to identify independent predictors for the no-reflow after primary PCI.</p><p><b>RESULTS</b>Incidence of the no-reflow was significantly lower in the β blocker group than in non-β blockers group (13.6% (35/257) vs. 21.2% (289/1 358), P = 0.017). Multivariable logistic regression analysis revealed that pre-PCI β blocker use was a protective predictor of the no-reflow (OR = 0.594, 95%CI:0.394-0.893, P = 0.012), while age ≥ 55 years old (OR = 2.734, 95%CI:1.959-3.817, P < 0.001), high neutrophil count (OR = 1.257, 95%CI: 1.169-1.351, P < 0.001), admission plasma glucose (OR = 1.060, 95%CI:1.018-1.103, P = 0.004), Killip classes IV (OR = 3.383, 95%CI:1.924-5.948, P < 0.001) and reperfusion time ≥ 4 h(OR = 1.503, 95%CI:1.124-2.009, P = 0.006) were risk factors for the development of no-reflow post PCI.</p><p><b>CONCLUSION</b>Previous long term β blockers use before STEMI is associated with lower incidence of no-reflow in patients with STEMI treated with primary PCI.</p>

ABSTRACT

Objective To investigate the clinical effects and significance of different-dose atorvastatin on soluble CD105(sCD105),high sensitive-C reactive protein(hs-CRP)and the parameters of heart rate turbulence in patients with acute coronary syndrome(ACS). Methods One hundred and six ACS patients were divided into three groups by random digits table: control group(30 patients, routine treatment),treatment group Ⅰ(38 patients, routine treatment + atorvastatin 20 mg), and treatment group Ⅱ(38patients, routine treatment + atorvastatin 40 mg). All patients were treated for 4 weeks. The levels of serum sCD105,hs-CRP,and the parameters of heart rate turbulence before and after treatment. Results Before treatment, the levels of turbulence onset(TO), turbulence slope(TS),sCD105 and hs-CRP in three groups had no significant difference(P > 0.05). After treatment, TO,sCD105 and hs-CRP decreased significantly,and TS increased significantly(P< 0.05 or < 0.01). The change amplitude of treatment group Ⅱ was the most obvious, and the levels of above mentioned index showed significantly difference compared with that of treatment group Ⅰ[TO:(0.22 ±0.18)% vs.(0.66 ± 0.23)%;TS:(6.22 ±0.83)ms/RR interval(RRI)vs.(3.90 ±0.73)ms/RRI;sCD105:(1.65 ±0.43)mg/L vs.(2.92 ±0.50)mg/L;hs-CRP:(1.68 ±0.55)mg/L vs.(2.08±0.61)mg/L](P <0.01). Correlation analysis showed the levels of sCD105 and hs-CRP had significantly positive correlation with TO(P < 0.01)and had negative correlation with TS(P < 0.01).Conclusions The atorvastatin treatment in patients with ACS may stabilize coronary vascular endothelial cells and atherosclerotic plaque, and improve autonomic nerve function. Larger doses of atorvastatin may get more benefit.

ABSTRACT

Objective To observe the therapeutic effects of the co-administration of γ-aminobutyric acid (CABA), sodium dimercaptopropane sulfonate (Na-DMPS) and vitamin B6 in large doses on liver and heart of rats with acute tetramine intoxication, and compare their separate effects of either GABA or Na-DMPS alone with those of the triad combination. Method Thirty rats were randomized into control group (n = 6), tetramine intoxication without treatment group (n = 6), tetramine intoxication treated with GABA group (n = 6), tetramine intoxication treated with Na-DMPS group (n = 6) and tetramine intoxication treated with triad combination (GABA + Na-DMPS + vitamin B6, GNDV n = 6) group. Samples of blood, liver tissue and heart tissue of rats with acute tetramine intoxication were collected immediately two hours after medication with different drugs. Serum alanine aminotrasferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) were measured, and the pathological changes of liver tissue and heart tissue were observed under microscope. Results The symptoms of poisoning were apparently relieved and the latency for convulsion/muscular twitch were obviously delayed in poisoned rats treated with GABA, Na-DMPS and GNDV separately. Furthermore, combination group showed the latent period delayed longer than either GABA or Na-DMPS groups The GABA, Na-DMPS and GNDV significantly lowered the serum levels of ALT, AST, CK and CK-MB in rats with tetramine intoxication, and those serum levels of enzymes were lower in GNDV group than those in either GABA group or Na-DMPS group. However, there were no difference in those serum enzymes between GABA group and Na-DMPS group. Moreover, the intoxicated rats treated with combination treatment had the slightest pathological changes in liver and heart (GNDV < GABA or Na-DMPS). Conclusions The co-administration of γ-aminobutyric acid, sodium demercaptopropane sulfonate and vitamin B6 in large doses for the treatment of tetramine intoxication is a method of choice.

ABSTRACT

Objective To discuss the imaging diagnostic features of adrenal injury. Methods The imaging features of the 29 patients of adrenal bruise and hernatoma (20 male and 9 females, average age 37) were retrospectively analyzed. The clinical appearances were all flank and hack pain, local sensitive to percus-sion and associated injury appearance. Among the 29 cases, 25 cases(86%) had adrenal injuries on right side, 2 cases(7%) on left side, and 2 cases(7%) on both sides, and no apparent abnormality was found in the relevant endocrine examination after injury. CT (n=29), MRI (n=5) and ultrasonography (n=6) were checked. CT follow-up were taken in 23 eases. MRI (n=1) and ultrasonography (n=l) were followed as well. Results The first-time exam coincidences of CT, MRI and sonography were 28/29 (97%), 5/5 (100%) and 3/6 (50%) respectively. One case of simple right-side adrenal hematoma 3 weeks after injury wasn't clearly diagnosed by CT, which was later diagnosed by MRI. The CT features of adrenal bruise were local or diffuse intumescence and focus high-density hemorrhage shadow. The CT appearances of acute stage adrenal hematoma were round-like high-density shadow without enhancement and the diameters were 1-3 cm. MRI appearances of 5 cases of subacute and chronic phase hematoma were typical high signal of T1WI, T2WI and DWI and toroid low signal around T2WI. Hematorna was not be enhanced when CT or MRI en-hancement scanning, and formed characteristic "nut-like" image feature with toroid high-density or high sig-nal enhanced shadow forming around. Uhrasonography appearances of 3 cases of hematoma were abnormal shadow of the adrenal gland. Conclusions CT is the prior imaging method for adrenal bruise and hemato-ma. MRI has the characteristic appearance for the few cases which are difficult to be identified by CT and ul-trasonography. Characteristic "nut-like" image feature is helpful for the diagnosis and differential diagnosis.
