RESUMO
OBJECTIVES@#To compare the clinical effect on Bell's facial palsy in the acute stage between the staging comprehensive treatment with acupuncture-moxibustion and western medication.@*METHODS@#Sixty patients with Bell's facial palsy in the acute stage were randomly divided into an observation group and a control group, with 30 cases in each one. The patients in the control group were administered orally with prednisone acetate tablets and methylcobalamin tablets until the 28th day of illness. In the observation group, the staging comprehensive treatment with acupuncture-moxibustion was adopted. On the affected side, Qianzheng (EX-HN 16), Yifeng (TE 17), Sibai (ST 2), Yangbai (GB 14), Jiache (ST 6), Dicang (ST 4) and Touwei (ST 8), etc. were stimulated. In the acute stage (Day 1 to 7 of illness), the routine acupuncture and the point-toward-point needle insertion were delivered, no any manipulation was exerted at acupoints, and the needles were retained for 30 min. In the subacute stage (Day 8 to 14 of illness), on the base of the treatment as the acute stage, the depth of needle insertion was adjusted at a part of acupoints and the even needling technique was operated by twisting needle. Besides, electroacupuncture (EA) was attached to Qianzheng (EX-HN 16) and Dicang (ST 4), with continuous wave of low intensity and high frequency, 100 Hz, for 20 min. In the recovery stage (Day 15 to 28 of illness), on the base of the treatment as the subacute stage, the heavy stimulation of acupuncture was given, in which, the sticking and lifting needle techniques were delivered after the needles were inserted from Sibai (ST 2) toward Dicang (ST 4), and from Dicang (ST 4) toward Jiache (ST 6), separately; warm needling was operated at Yifeng (TE 17), and EA changed to stimulate the acupoints with the intermittent wave of high intensity and low frequency, 2 Hz, for 30 min. Acupuncture-moxibustion was given once every other day until the end of the 28th day of illness. The level of House-Brackmann facial nerve function rating scale (H-B grade),the score of Sunnybrook facial nerve grading system (Sunnybrook), the score of facial disability index (FDI), the temperature difference in the infrared thermal imaging facial area and electromyogram (EMG) situation of the affected muscle group were observed before and after treatment in the two groups. Using musculoskeletal ultrasound,the facial nerve diameter was detected and the clinical effect was compared between the two groups.@*RESULTS@#After treatment, the level of H-B grade, Sunnybrook score, the scores of physical function and social life function in FDI were improved when compared with those before treatment in the patients of either group (P<0.01, P<0.05), and the results of these evaluations in the observation group were better than those of the control group (P<0.05). After treatment, the temperature difference of the frontal area, the eye area, the zygomatic area and the mouth corner was declined in comparison with that before treatment in the two groups (P<0.05), and the temperature difference in each area in the observation group was lower than that of the control group (P<0.05).The root mean square (RMS) of the frontal muscle group, the zygomatic muscle group and the orbicularis muscle group on the affected side increased in comparison with that before treatment in the two groups (P<0.01), and RMS of the observation group was higher than that of the control group (P<0.05) after treatment. Before treatment, the diameter of the facial nerve on the affected side was larger than that on the healthy side (P<0.01), and after treatment, the diameter on the affected side was reduced when compared with that before treatment in the two groups (P<0.01); the diameter of the facial nerve on the affected side in the observation group was smaller than that of the control group (P<0.05), while, the diameter on the affected side was larger when compared with the healthy side in the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), higher than that of the control group (83.3% [25/30], P<0.05).@*CONCLUSIONS@#The staging comprehensive treatment with acupuncture-moxibustion is clearly effective on Bell's facial palsy in the acute stage, which affirms the effectiveness of acupuncture-moxibustion for the acute stage of Bell's facial palsy in comparison with conventional western medication.

The strikingly rapidly mutating nature of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)genome has been a constant challenge during the coronavirus disease 2019(COVID-19)pandemic.In this study,various techniques,including reverse transcription-quantitative polymerase chain reaction,antigen-detection rapid diagnostic tests,and high-throughput sequencing were analyzed under different scenarios and spectra for the etiological diagnosis of COVID-19 at the population scale.This study aimed to summarize the latest research progress and provide up-to-date understanding of the methodology used for the evaluation of the immunoprotection conditions against future variants of SARS-CoV-2.Our novel work reviewed the current methods for the evaluation of the immunoprotection status of a specific population(endogenous antibodies)before and after vaccine inoculation(adminis-tered with biopharmaceutical antibody products).The present knowledge of the immunoprotection status regarding the COVID-19 complications was also discussed.Knowledge on the immunoprotection status of specific populations can help guide the design of pharmaceutical antibody products,inform practice guidelines,and develop national regulations with respect to the timing of and need for extra rounds of vaccine boosters.
RESUMO
Objective:To compare the predictive ability of SpO 2/FiO 2(S/F) and ROX index on the failure of high-flow nasal cannula(HFNC)therapy in children with acute respiratory failure after congenital heart disease surgery, and to identify the best cut-off point. Methods:Through a case-control study, the clinical data of 371 children with acute respiratory failure after congenital heart surgery treated with HFNC admitted to Guangzhou Women and Children′s Medical Center from January 2018 to December 2021 were retrospectively analyzed.The primary outcome was the need for re-intubation within 48 h after extubation of invasive ventilation.The ability of S/F and ROX index to predict HFNC failure was compared, and the optimal cut-off point was determined based on the area under the curve (AUC) of receiver operating characteristic curve.Results:A total of 371 children were included, of whom 27 (7.3%) eventually required mechanical ventilation within 48 h. The S/F prediction accuracy was highest after 6 h of HFNC treatment(AUC=0.712, 95% CI 0.599-0.825, P=0.001), and the best cut-off point for S/F was 178 mmHg(1 mmHg=0.133 kPa)(sensitivity 74.9%, specificity 69.6%). Whereas the prediction accuracy of the ROX index was highest after 12 hours of HFNC treatment, the AUC was 0.737(95% CI 0.623-0.851, P=0.002), and the best cut-off point of the ROX index was 5.865(sensitivity 72.4% specificity 66.7%). The difference in AUC between S/F after 6 h of HFNC treatment and ROX after 12 h was not statistically significant ( P=0.444), with higher sensitivity and specificity, and earlier prediction time(6 hours) in the former. Conclusion:Children with acute respiratory failure after congenital heart surgery have a strong predictive ability of S/F after 6 h of HFNC treatment, and the risk of HFNC treatment failure is higher in children with S/F <178 mmHg.
RESUMO
Objective:To explore the chain mediating effect of self-efficacy and positive coping styles between nurses′ adversity quotient on work engagement, so as to provide a theoretical reference for nursing managers to promote work engagement.Methods:A convenience sampling method was used to select 512 nurses from four tertiary hospitals in Shaanxi Province, and a cross-sectional study was conducted on them using the general information questionnaire, Adversity Response Profile, General Self-Efficacy Scale, Simplified Coping Style Questionnaire and Utrecht Work Engagement Scale-9.Results:The total scores of nurses' adversity response profile, self-efficacy, positive coping style and work engagement were 132.00(120.00, 139.00), 27.00(23.00, 29.00), 24.00(20.00, 25.00), 27.00(25.00, 35.00) points. Nurses' work engagement was significantly positively correlated with adversity quotient, self-efficacy and positive coping styles( r values were 0.523-0.614, all P<0.01). The independent mediation of self-efficacy or positive coping styles and the chain mediation of both accounted for 23.6%,40.9% and 15.9% of the total effect respectively. Conclusions:Nurses′ adversity quotient not only directly affected work engagemnet, but also indirectly affected work engagement through self-efficacy and positive coping style. The research suggested that managers should pay attention to the improvement of nurses′ self-efficacy and positive coping style, so as to promote nurses′ work engagement.
RESUMO
Objective:To investigate the mediating effect of rumination in primiparae on the expectation gap of social support and postpartum depression, so as to provide a reference basis for early detection and intervention in the regulation of meternal postpartum depression.Methods:In this cross-sectional study, questionnaires were administered from November 2021 to March 2022 using the general information questionnaire, the Ruminant Thinking Response Scale, the Postpartum Social Support Scale, and the Edinburgh Postpartum Depression Scale to 266 primiparae at three tertiary level A hospitals, the First Affiliated Hospital of Xi′an Jiaotong University, the Second Affiliated Hospital of Xi′an Jiaotong University, and the Northwest Women′s and Children′s Hospital, for postpartum review, and the relationship between ruminant thinking, social support expectation gap, and postpartum depression was analyzed using correlation analysis, structural equation modeling, and application of Bootsrap method.Results:The social support expectation gap, ruminative thinking, and postpartum depression average scores were (16.74 ± 12.77), (39.43 ± 4.14), (6.77 ± 2.77) points, respectively.There were positive correlations between social support expectation gap and ruminative thinking, postpartum depression, and ruminative thinking and postpartum depression ( r=0.62, 0.75, 0.70, all P<0.01). Primiparae ruminative thinking partially mediated the relationship between social support expectation gap and postpartum depression, with the mediating effect accounting for 22% of the total effect. Conclusions:Social support expectation gap can directly affect the occurrence of postpartum depression, but also indirectly through ruminative thinking, and postpartum depression can be prevented and intervened from the perspective of reducing ruminative thinking in clinical practice.
RESUMO
Objective To explore the effect of Linc00460 on the aerobic glycolysis of breast cancer (BC) cells through sponge adsorption of miR-320a. Methods The qRT-PCR method was used to detect Linc00460 and miR-320a expression levels in normal breast epithelial cell line MCF-10A and five BC cell lines. The effect of interfering Linc00460 on miR-320a expression was detected by qRT-PCR. The double luciferase reporter gene experiment was used to analyze the targeting relationship between miR-320a and Linc00460. In addition, the si-Linc00460 and miR-320a inhibitor were co-transfected into MDA-MB-231 cells, and the expression level of miR-320a in the cells was detected by qRT-PCR; cell proliferation ability was measured by the MTT method; glucose uptake rate was detected by 2-NBDG method; the content of lactic acid in the cell supernatant was detected by colorimetric method; the key enzymes of glycolysis was detected by the enzyme activity kit; and the expression levels of the key proteins in the glycolysis pathway were detected by Western blot. Results Linc00460 was highly expressed in five BC cell lines, while miR-320a was lowly expressed as compared with MCF-10A cells. The expression of miR-320a in MDA-MB-231 cells significantly increased after interfering with Linc00460. The double luciferase reporter gene experiment confirmed that miR-320a and Linc00460 could target binding. Interfering with the expression of Linc00460 could inhibit MDA-MB-231 cells proliferation (all P=0.000), reduce the rate of cellular glucose uptake and the content of lactic acid in the cell supernatant (all P=0.000), inhibit the activities of PFK, PK, and LDH enzymes (all P=0.000), and downregulate the protein expression levels of PFKM, GLUT1, and LDHA (all P=0.000). Meanwhile, inhibition of miR-320a could reverse the inhibitory effect of si-Linc00460 on the proliferation and glycolysis of MDA-MB-231 cells (all P=0.000 or 0.001). Conclusion Linc00460 might adsorb miR-320a, consequently leading to upregulation of PFKM expression, thereby promoting aerobic glycolysis in BC cells.

Objective:To evaluate the role of brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB) signaling pathway in 17β estradiol-induced reduction of long-term cognitive impairment induced by multiple propofol anesthesia in developing rats.Methods:Eighty 7-day-old clean-grade healthy newborn Sprague-Dawley rats of both sexes, weighing 11-17 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (group C), propofol group (group P), 17β estradiol plus propofol group (EP group) and 17β estradiol plus propofol plus BDNF/TrkB signaling pathway blocker K252a group (K group). Propofol 80 mg/kg was intraperitoneally injected every day for 5 days in P, EP and K groups.The equal volume of fat emulsion was given instead in group C. In EP and K groups, 17β estradiol 600 μg/kg was subcutaneously injected at 30 min before propofol injection.BDNF/TrkB signaling pathway blocker K252a 100 μg/kg was intraperitoneally injected in group K. Morris water maze test was performed on days 30-34 after birth to assess the cognitive function.The rats were sacrificed after the end of Morris water maze test, and the hippocampal tissues were removed for determination of the apoptosis rate of hippocampal neurons (by flow cytometry), expression of BDNF, p-Trkb and cleaved caspase-3 (by Western blot and immunofluorescence), and expression of Bcl-2 and Bax mRNA (by real-time polymerase chain reaction) and for microscopic examination of the pathological changes in hippocampal CA1 region (with a light microscope). Bax mRNA/Bcl-2 mRNA ratio was calculated. Results:Compared with group C, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, the expression of BDNF and p-TrkB was down-regulated, the expression of cleaved caspase-3 was up-regulated, the apoptosis rate of hippocampal neurons and Bax mRNA/Bcl-2 mRNA ratio were increased ( P<0.05), and the pathological changes in hippocampal CA1 region were accentuated in group P. Compared with group P, the escape latency was significantly shortened, the number of crossing the original platform was increased, the expression of BDNF and p-TrkB was up-regulated, the expression of cleaved caspase-3 was down-regulated, the apoptosis rate of hippocampal neurons and Bax mRNA/Bcl-2 mRNA ratio were decreased( P<0.05), and the pathological changes in hippocampal CA1 region were attenuated in group EP.Compared with group EP, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, the expression of BDNF and p-TrkB was down-regulated, the expression of cleaved caspase-3 was up-regulated, the apoptosis rate of hippocampal neurons and Bax mRNA/Bcl-2 mRNA ratio were increased( P<0.05), and the pathological changes in hippocampal CA1 region were accentuated in group K. Conclusions:BDNF/TrkB signaling pathway is involved in 17β estradiol-induced reduction of long-term cognitive impairment induced by multiple propofol anesthesia in developing rats.

Objective To study perioperative period conditions of total and partial colpocleisis with severe pelvic organ prolapse(POP)in elderly patients. Methods From Jan. 2014 to Oct. 2017286 severe POP elderly patients underwent total or partial colpocleisis. The mean age was(76.0±5.1)years(60-90 years). Of which,220 patients(76.9％, 220/286)presented more than one kind of medical disease. The operative time, intraoperative blood loss, hospital stay after surgery, postoperative complications, preoperative urinary dysuria symptoms of total and partial colpocleisis in treatment of 286 patients were analyzed. Results In 286 patients, 172 patients(60.1％)underwent total colpocleisis and 114 patients(39.9％) underwent partial colpocleisis. Totally 48 patients(16.8％)in 286 patients underwent anti-urinary incontinence procedure. The mean operating time of 286 patients was(67 ± 22)minutes, the mean blood loss was(52 ±57)ml, the mean hospital stay after surgery was(5.9 ± 1.9)days(2-16 days). The rate of postoperative complications was 8.7％(25/286). Those complications including 1 case of bladder injury during operation, 3 cases of postoperative pelvic hematoma, 1 case of intestinal obstruction, 5 cases of atrial fibrillation, 10 cases of postoperative morbidity, 3 cases of pulmonary embolism, 1 case of lower limb thrombosis, 1 case of urinary retention underwent electrical stimulation treatment because of ineffective application of urinary retention catheter. The mean operating time was(67±22)minutes in total colpocleisis and(68±20) minutes in partial colpocleisis(P>0.05), the mean blood loss was(58±62)ml in total colpocleisis and(41± 45)ml in partial colpocleisis(P>0.05), the mean hospital stay after surgery was(5.9 ± 1.9)days in total colpocleisis and(6.0 ± 1.8)days in partial colpocleisis(P>0.05), the rate of post operative complications was 8.1％(14/172) in total colpocleisis and 9.6％(11/114)in partial colpocleisis(P>0.05), respectively;those four of comparisons showed no significant difference. There were 129 patients(45.1％, 129/286)with voiding difficulty before surgery;the mean postvoid residual volumes of the above two operation types of people after operation were(35 ± 43)and(34 ± 41)ml, which showed no significant difference(P>0.05). Conclusions Colpocleisis is a safe and effective management in selected elderly patients with severe POP, who no longer desire to maintain vaginal coital function. There is no significant difference in the perioperative period conditions between total and partial colpocleisis. The choice of surgical procedure is based on factors such as the presence or absence of malignancy in the uterus, age and willingness of the patient, and general condition.

RESUMO
Objective To investigate the status and influencing factors of pleasant events among community-dwelling dementia patients. Methods Totally 266 community-dwelling dementia patients were recruited from Bei-jing,Guangzhou and Tianjin,and were investigated with the Chinese-version Pleasant Events Schedule-AD(PES-AD). Results The overall score of PES-AD was (14.0±6.7). The factor scores from high to low were sensory stimulation activities(0.9±0.5),family activities(0.8±0.5),emotional stimulation activities(0.8±0.4) and autonomy activities(0.6± 0.5). Multiple linear regression showed that the severity of disease,without chronic disease,educational level of de-mentia patients and their caregivers were significant influencing factors of pleasant events,which explained 41.1% of the total variance. Conclusion Sensory stimulation activities of community-dwelling dementia patients were relatively satisfactory,followed by family activities and emotional stimulation activities,but autonomy activities were relatively unsatisfactory. It is suggested to choose appropriate pleasant activities according to the severity of disease for de-mentia patients to improve their quality of life.
RESUMO
Objective To investigate the mechanism of Guiqiyiyuan Ointment (GO) for preventing and treating 12C6+ beam radiation induced lung and kidney bystander effect to provide a new strategy for prevention and treatment of clinical radiation injury. Methods Sixty healthy male Wistar rats were randomly and equally divided into 3 groups: NC group, SR group (simple radiation 2ml/kg), GO group(GO 2ml/kg intragastric administration for 7 days). The right side of the lung was modeled by 12C6+beam radiation. After modeling, the rats were killed at 48h. The left lung, left and right kidney tissues were taken from the rats. The DNA methylation rate was detected by ELISA assay, pathological changes were observed by HE staining, and the expressions of Dnmt1, Dnmt3a and Dnmt3b were detected by immunohistochemistry. Results Compared with the NC group, the level of DNA methylation was decreased significantly (P<0.01), the left lung showed inflammation, no abnormal finding was seen in the left and right kidneys, and the expressions of Dnmt1, Dnmt3a and Dnmt3b were significantly increased in the SR group (P<0.01). Compared with the SR group, the level of DNA methylation was increased significantly (P<0.01), the left lung inflammation became better, and the expressions of Dnmt1, Dnmt3a and Dnmt3b were significantly decreased in the GO group (P<0.01). Dnmt1, Dnmt3a and Dnmt3b proteins were expressed in the cytoplasms of bronchial and renal tubular epithelial cells in all the groups. The NC group presented as light brown-brown staining, showing a weak positive expression, the SR group as brown-brown staining, showing astrong positive expression, and the GO group as light brown-brown staining, showing a moderate positive expression. Conclusion The GO can reduce the bystander effect caused by 12C6+ beam radiation, and its mechanism is related to improving the level of DNA methylation.

AIM To determine the contents of polymethoxylated flavones in Citri Reticulatae Pericarpium from eleven cultivar origins.METHODS HPLC was applied to screening extraction solvents (methanol,anhydrous ethanol,95％ ethanol,ethyl acetate and petroleum ether).Ultraviolet-visible spectrophotometry was adopted in the content determination of polymethoxylated flavones in eighteen batches of samples,nobiletin was taken as a reference substance,and the detection wavelength was set at 330 nm.RESULTS Ethyl acetate exhibited the best extraction effect,so it was selected as extraction solvent.Nobiletin showed a good linear relationship within the range of 3.024-13.104 μg/mL (R2 =0.999 8),whose average recovery was 101.37％ with the RSD of 1.34％.The contents of polymethoxylated flavones had obvious differences among samples from different cultivar origins,which were relatively high from Citrus reticulata ‘ Chachi’,Citrus reticulata ‘ Dahongpao’,Citrus reticulata ‘ Tangerina’,Citrus reticulata ‘ Ponkan’,Citrus reticulata ‘ Kinokuni’and Citrus reticulata ‘ Shiyueju’(more than 0.4％).CONCLUSION This simple and accurate method can effectively eliminate the interference of another flavonoids,which is suitable for the content determination of polymethoxylated flavones in Citri Reticulatae Pericarpium.
RESUMO
Objective@#To evaluate the effect of breast massage at different time in the early period on maternal lactation after cesarean section.@*Methods@#80 women delivered by cesarean section were randomly selected from maternity ward of a hospital in Shandong province during Jan. 2013 to Jan. 2015; which were divided into four groups, with 20 patients in each. Three groups received 3 times of breast massage every 24 hoursbeginning from 2, 12 and 24 h after cesarean section, respectively. The control group didn't receive any breast massage. The starting time and status of lactation were observed and recorded after cesarean section. 5 ml venous blood sample was drawn from each patient respectively at 2 h before cesarean, 6, 12, 24, 48 and 72 h after cesarean to test the level of serum prolactin. The lactation status of each group was compared.@*Results@#The P50 (P25-P75) of starting time of lactation of the three massage groups and control group were 3 (2-6) h, 4 (2-8) h, 4 (3-12) h and 4 (2-12) h, respectively, whose differences showed no statistical significance (H=3.32, P=0.345).The number of delivered women with adequate lactation 24 hours after cesarean was 10 in the group who received massage beginning from 2 h after cesarean; while the number was only 2 in the control group. The number of delivered women with adequate lactation 48 hours after cesarean was 18 in the group who received massage beginning from 2 h after cesarean; while the number was 8 in the control group. The differences showed statistical significances (P values were 0.021 and 0.008, respectively). The serum prolactin level in the group of delivered women who received massage from 2 h after cesarean was separately (195.9±78.5), (176.0±96.5), (216.4±110.0), (190.0±56.8) and (184.8±69.6) μg/L at 2, 12, 24, 48 and 72 h after cesarean, which were significantly higher than those in the control group (which were (128.8±40.6), (127.3±66.8), (162.2±58.8), (145.1±64.7) and (141.7±49.3) μg/L, respectively) (P=0.007).@*Conclusion@#Breast massage beginning from 2 hours after cesarean section can effectively improve the lactation status of delivered women.
RESUMO
Objective To investigate the clinical efficacy of capecitabine metronomic chemotherapy in the maintenance of elderly patients with metastatic breast cancer. Methods Fifty-six patients with metastatic breast cancer treated in Jiangsu Shengze Hospital from April 2014 to April 2017 were randomly divided into two groups according to random number table method: metronomic chemotherapy group (n = 28) and conventional chemotherapy group (n = 28). The patients in the metronomic chemotherapy group were treated with capecitabine 500 mg, 2 times/d and continuous oral administration. The conventional chemotherapy group received capecitabine 1 250 mg, 2 times/d for 14 days, rested for 7 days, 21 days was a course of treatment.After two courses,the clinical efficacy,toxicity and quality of life were evaluated. Results There were no significant differences in RR and DCR between the metronomic chemotherapy group and conventional chemotherapy group (RR: 39.3 % vs. 42.8 %, DCR: 89.3 % vs. 85.7 %, both P > 0.05). The median progression-free survival (PFS) time in the metronomic chemotherapy group was 5.8 months (95 % CI 3.23-7.44, P= 0.764) and median overall survival (OS) time was 7.9 months (95 % CI 4.15-7.95, P=0.519). The median PFS time in the conventional chemotherapy group was 7.2 months (95 % CI 3.32-6.33, P=0.835), median OS time was 10.3 months (95 % CI 4.08-7.37, P=0.463). There was no significant difference between the two groups (both P> 0.05). The incidences of hand-foot syndrome, myelosuppression and digestive tract reaction in conventional chemotherapy group were higher than those in metronomic chemotherapy group, there were significant differences between the two groups (all P < 0.05). No Ⅲ-Ⅳ level adverse reactions were found in the metronomic chemotherapy group. The overall rate of improvement of the quality of life in the metronomic chemotherapy group was significantly higher than that in the conventional chemotherapy group (92.9 % vs. 78.8 %, χ 2= 7.629, P < 0.05). Conclusion The clinical efficacy of capecitabine metronomic chemotherapy in the maintenance of elderly patients with metastatic breast cancer is similar to conventional dose maintenance therapy,but it can not only reduce the side effects, but also improve the quality of life of patients.
RESUMO
Objective To investigate the clinical characteristics and angiographic findings of cardiogenic shock(CS)following acute myocardial infarction(AMI) in elderly patients.Methods Between January 2015 and April 2016,we carried out a retrospective observational analysis of consecutive elderly patients in Tianjin Chest Hospital,who suffered CS-complicating AMI.Emergency angiography and percutaneous coronary intervention(PCI) were performed after admission.All selected patients were divided into CS and non-CS groups according to whether CS occurred.Electrocardiograph (ECG),cardiac enzyme testing,and ultrasound cardiography were performed after admission to monitor the occurrence of CS.Results The incidence of CS-complicating AMI was 8.33％ (34/408) in elderly patients.Among all CS patients enrolled,the aged patients accounted for 91.89 ％ (3 4/3 7).In-hospital mortality rate was 2 9.41 ％ (10/3 4).There were significant differences between two groups in WBC,H s-CRP,blood glucose,CR and ALT (t =2.403,4.596,6.778,6.109,each P＜0.05).The NT-Pro BNP level,the time of FMC,the frequency of left main and multivessel disease were higher in the CS group than in the non-CS group (each P ＜ 0.05).Conclusions Elderly patients are bearing high risk of CS following AMI.Prolonged FMC time and the presence of left main and/or multivessel lesion are independent risk factors for the development of CS.The optimal revascularisation strategy can improve the clinical outcome of patients with CS.
RESUMO
With the example analysis method, this paper discussed the feasibility of flipped class to permeate the medical ethics education into medical English teaching. Practice has proved that consciously combining lan-guage teaching with the medical ethics education on various modern networks teaching platform enabled students to foster a correct view of medical ethics and to be qualified medical workers.
