ABSTRACT
Objective:To investigate the effects of levosimendan combined with Shengmai injection on pump failure in patients with acute myocardial infarction and its effects on tissue perfusion and oxygen metabolism. Methods:A total of 110 patients with acute myocardial infarction and pump failure who received treatment in Jiaozhou People's Hospital (South Branch) from July 2019 to December 2020 were included in this study. They were randomly assigned to receive either routine treatments including electrocardiography monitoring, oxygen saturation monitoring, oxygen therapy, dual antiplatelet therapy, statins, vasoactive drugs, and nitrates (control group, n = 55) or levosimendan combined with Shengmai injection based on routine treatments (observation group, n = 55) for 10 successive days. Curative efficacy, cardiac function, tissue perfusion, and oxygen metabolism capacity were compared between the control and observation groups. The 1-month mortality rate was compared between the two groups. Results:Total effective rate was significantly higher in the observation group than in the control group [58.18% (32/55) vs. 38.18% (21/55), χ2 = 4.41, P < 0.05]. After treatment, left ventricular end-diastolic diameter, left ventricular ejection fraction, and stroke volume were superior in the observation group to in the control group ( t = 2.12, –5.85, –7.33, all P < 0.05). Oxygen partial pressure, oxygenation index, central venous oxygen saturation, lactate, lactate clearance rate, and urine volume in the observation group were (103.53 ± 9.85) mmHg, (247.69 ± 18.95) mmHg, (77.56 ± 3.59)%, (3.02 ± 0.45) mmol/L, (42.89 ± 5.22)%, (40.88 ± 1.64) mL/hour, respectively, and they were (95.47 ± 11.98) mmHg, (194.69 ± 16.52) mmHg, (70.88 ± 2.13)%, (3.58 ± 0.51) mmol/L, (36.89 ± 5.14)%, and (36.55 ± 2.23) mL/hour, respectively in the observation group. There were significant differences in these indices between the control and observation groups ( t = –3.85, –15.64, –11.87, 3.11, –6.07, –11.27, all P < 0.001). At 1 month of follow-up, mortality rate was significantly lower in the observation group than in the control group [3.64% (2/55) vs. 16.36% (9/55), χ2 = 4.95, P < 0.05]. Conclusion:Levosimendan combined with Shengmai injection is a highly effective treatment for pump failure in acute myocardial infarction. It can improve cardiac function and tissue perfusion, increase oxygen metabolism capacity, and decrease mortality.
ABSTRACT
Objective:To observe the expression characteristics of eukaryotic translation initiation factor 2α(eIF2α), and analyze its proliferation regulation effect on fibroblasts of rheumatoid arthritis synovium.Methods:The synovial tissues were collected in patients with rheumatoid arthritis(RA)(40 cases) and osteoarthritis(OA)(40 cases). EIF2α and proliferating cell nuclear antigen(PCNA) were detected by immunohistochemistry method. Fibroblast cell line of rheumatoid arthritis synovium(MH7A) were cultured to establish si-eIF2α group(siRNA-eIF2α plasmid transfection), vector transfection group and blank control group in vitro. PCNA was detected by Western blot method, cell proliferation activity was detected by CCK-8 method. χ2 test was performed on count data, two-sample t-test was performed on quantitative data, one-way analysis of variance (ANOVA) was performed to compare the means of more than two groups, regression equation was calculated by correlation regression analysis. Results:The positive rate of eIF2α was significantly higher in RA synovial fibroblasts than that of OA [52.5%(21/4) vs 20.00%(8/20), χ2=9.14, P=0.003]. Positive correlation was found between eIF2α and PCNA in RA ( Y=0.366 X+2.220, P=0.001) . Compared with blank control group and vector transfection group, cell proliferation activity decreased significantly in si-eIF2α group of MH7A cell line at 72 h [(0.65±0.08) vs (0.96±0.12) vs (1.09±0.06), F=4.52, P=0.022] and 96 h [(1.13±0.14) vs (1.42±0.97) vs (1.56±0.12), F=9.87, P=0.001) , PCNA expression decreased significantly [(0.84±0.15) vs (1.32±0.18) vs (1.28±0.14), F=5.22, P=0.012) . Conclusion:High expression of eIF2α can promote the proliferation of fibroblasts of RA synovium.
ABSTRACT
Objective To observe the therapeutic effect of Radix Astragali,Radix Rehmanniae combined with glucocorticoid(GC) in treating patients with systemic lupus erythematosus(SLE) and its influence on some experimental indexes.Methods 72 cases of SLE were randomly recruited into the integrated traditional Chinese and western medicine treated group (treated group) and the western medicine treated group (control group).The control group was treated with prednisone and cyclophosphamide,while the treated group was treated with Radix Astragali and Radix Rehmanniae on the basis of the control group.Both groups had been treated for 6 months as a therapy course.The use of prednisone dosage were recorded and its influence on indexes of clinical and laboratory value were observed.Results 27 SLE patients in the treated group and 34 in the control group were completely observed.The dosages of prednisone in both groups were decreased gradually after the state of disease had been relieved.The predrisone dosage in the treated group was lower than that in the control group in the therapy course(15.41 ±7.65)mg vs (17.25±8.83)mg,but without significant difference (t=0.85,P＞0.05).The total decreased prednisone dosage in the treated group (50.12±12.53 mg) was slightly higher than that in control group(48.96± 13.71) mg (t=0.34,P＞0.05).The ratio of cases who had to add prednisone for aggravating disease in treated group(15.92％) was less than that in the control group (38.24％),the difference was significant (x2=3.24,P＜0.05).The incidence rate of cushing syndrome,infection,diseases of digestive,cardiovascular anomalies in the treated group was slightly less than the control group (x2=0.42,0.98,0.01,0.03respectivly,P＞0.05),but the number of insomnia and hot flush were significantly larger in the control group than the treatment group (x2=4.24,5.93,P＜0.05).No difference about the SLEDAI,ESR,CRP,Blood Complement3,Blood imune globinG was found between the two groups (t=2.16,1.04,1.18,0.26,1.61 respectively,P＞0.05),and 24 hours urinary protein count decreased significantly in the treated group (1.06 ± 0.12) g/L,compared with control group (1.42 ± 0.54) g/L,(t =3.78,P ＜ 0.05 ).Conclusion Radix Astragal,Radix Rehmanniae combined with conventional treatment of western medicine could withdraw corticosteroid smoothly,relieve symptoms and alleviate some side-effects of western medicine.
ABSTRACT
Objective To evaluate the effect of the patient's preoperative visit to the operating room on the patient's apprehension before operation.Methods One hundred and Sixty patients aged 16-64 yr with fear visual analog scale (FVAS) score≥4 scheduled for elective surgery were randomly divided into 2 groups(n=80 each):control group and study group.In control group the anesthesiologists visited their patients the day before operation ns usual;while in study group the anesthesiologists brought their patients to the operating room,showed them the environment and anesthesia equipment and assured of the safety of the operation and anesthesia.The degree of fear was scored according to FVAS (O=no fear,1-3 mild,4-6 moderate,7-10 severe) and was evaluated on the 1st morning after admission(T1),the night before operation(T2)and before induction of anesthesia(T3).MAP and HR at T1-3 and blood glucose level at T1,3 were mensured and recorded.Results The patient's preoperative apprehension was significantly allayed by patient's preoperative visit to the operating room.The MAP,HR,incidence of moderate and severe fear at T2,3 and blood glucose level at T3 were significantly lower in study group than in control group.Conclusion Patient's preoperative visit to the operating room can allay precperative apprehension.
ABSTRACT
Objective To explore the relationship between P-selection,nitric oxide(NO),high-sensitive-C-reactive protein(hs-CRP)and type 2 diabetes mellitus(T2DM)with macroangiopathy.Methods In sernm of 125 T2DM subjects(60 subjects with macroangiopathy and 65 subjects without macroangiopathy)and 55 normal controls,the activity of P-selection,NO and hs-CRP was detected by ELISA,Nitrate Reductase Assay and scattering immunoturbidimetric method,respectivley.Results The activity of serum P-selection and hs-CRP was significantly higher in diabetic macroangiopathie group than in non macroangiopathic group and control normal.Serum NO was significantly lower in diabetic rnacroanglopathic group than in non macroangiopathic group and control normal.Serum P-selection was positively correlated with hs-CRP-systolic blood pressure(SBP),LDL-C,and was negatively correla- ted with NO:P-selection,hs-CRP,LDL-C and SBP were independently risk factors for T2DM with macroangiopathy. Conclusion Determination of P-selection and NO is very important for prevention and diagnosis of diabetic mac- roangiopathy in early stage.
