Objective To investigate the feasibility of the upper- arm electronic sphygmomanometer for evaluating the blood pressure in patients with atrial fibrillation. Methods Consecutive hospitalized patients with atrial fibrillation for coronary angiography were selected, and the application of upper- arm electronic sphygmomanometer and mercury sphygmomanometer of blood pressure were applied and in the process of coronary angiography, the radial artery invasive blood pressure was recorded and the correlation was analyzed. Results Mercury sphygmomanometer and radial artery invasive blood pressure measurement had a good consistency on systolic blood pressure, diastolic blood pressure, pulse pressure, mean arterial pressure in atrial fibrillation patients, the differences were not statistically significant (P>0.05). Upper- arm electronic sphygmomanometer and radial artery invasive blood pressure measurement had some consistency (pulse rate range, pulse rate of 70-90 beats / min) on systolic blood pressure, diastolic blood pressure, pulse pressure, mean arterial pressure in atrial fibrillation patients, the differences were not statistically significant (P>0.05). Upper-arm electronic sphygmomanometer and mercury sphygmomanometer had some consistency (pulse rate range, pulse rate of 70-90 beats / min) on systolic blood pressure, diastolic blood pressure, pulse pressure, mean arterial pressure in atrial fibrillation patients, the differences were not statistically significant (P>0.05). The correlation between mercury sphygmomanometer and radial artery invasive blood pressure measurement were found on systolic blood pressure, diastolic blood pressure, pulse pressure, mean arterial pressure in atrial fibrillation patients (r=0.71-0.78, P<0.05),which were better than those of upper- arm electronic sphygmomanometer and radial artery invasive blood pressure measurement (r=0.53-0.70, P <0.05). Conclusions The upper- arm electronic sphygmomanometer can be used for the assessment of blood pressure in patients with atrial fibrillation.

Objective: To study the risk factors for prevalence of acute myocardial infarction (AMI) in young and middle-aged population. Methods: A prospective cohort study was conducted in 110100 subjects at the age of (18-98) years who received physical examination in Kailuan Group from 2012-06 to 2014-10. Based on the limitations of male≤53 years and female≤63 years, a total of 62367 subjects were enrolled in our study. The subjects were followed-up for 2 years by the end point event of AMI to analyze the risk factors ofAMI occurrence. Results: According to AMI occurrence at the follow-up period, the subjects were divided into 2 groups: AMI group, n=56 and Control group, n=62152. Compared with Control group, AMI group had increased BMI, SBP, DBP and elevated blood levels of LDL-C, TG; AMI group also showed the higher ratios of subjects with the history of diabetes and taking anti-hypertension medication. Cox proportional hazard regression analysis indicated that age (RR=1.37), male (RR=60.54), LDL-C (RR=1.12), and TG (RR=5.93) were the risk factors forAMI occurrence in young and middle-aged population, allP<0.05. Conclusion: Age, male gender, blood levels of LDL-C, and TG were the risk factors for AMI occurrence in young and middle-aged population.

Objective:To compare the efficacy and safety of domestic 16-row and imported 8-row mobile CT in clinics.Methods:A total of 1469 patients accepted domestic 16-row mobile CT head scans (1604 times) from March 2017 to August 2018 in Bayi Brain Hospital Affiliated to 7 th Medical Center of General Hospital of People's Liberation Army and Langfang Aidebao Hospital; and 15510 patients accepted imported 8-row mobile CT head scans (24994 times) from January 2016 to August 2018 in Bayi Brain Hospital Affiliated to 7 th Medical Center of General Hospital of People's Liberation Army. All patients underwent horizontal plain and enhanced head scans, cerebral CT angiography (CTA), and helical 3D imaging; and the imaging quality, operating power consumption, computed tomography dose index volume (CTDIvol) and stability within scanning volume ranges under different scanning modes of the two CT scans were compared. Results:(1) Imaging quality: the horizontal scanning of domestic 16-row mobile CT could clearly display low-density tissues such as the eyeball, optic nerve, brain stem, sulcus and cerebral gyrus; the imaging quality of both CT scans in patients with traumatic subdural hematoma and ischemic stroke completely met the clinical diagnosis and treatment standards. (2) Operating power consumption: the per-hour operating power consumption of domestic 16-row mobile CT ([0.286±0.018] kW·h) was obviously lower than that of imported 8-row mobile CT ([0.485±0.028] kW·h). (3) Radiological hazard: the CTDIvol of the horizontal scanning volume range in domestic 16-row mobile CT ([36.270±0.281] mGy) was significantly lower than that in the imported 8-row mobile CT ([82.520±0.441] mGy, P<0.05); the CTDIvol of enhanced axis scan volume range in the domestic 16-row mobile CT ([36.270±0.335] mGy) was significantly lower than that in the imported 8-row mobile CT ([70.728±0.424] mGy, P<0.05); the CTDIvol in the volume of CTA imaging of domestic 16-row mobile CT ([20.600±0.087] mGy) was significantly lower than that in the imported 8-row mobile CT ([29.300±0.335] mGy, P<0.05). The domestic 16-row mobile CT was designed with shock absorbers and guides; domestic 16-row mobile CT had small load, a low center of gravity, and good stability as compared with imported 8-row mobile CT. Conclusion:In terms of head scanning applications, the imaging quality of domestic 16-row mobile CT and imported 8-row mobile CT is in full compliance with clinical diagnostic standards, but the energy consumption and radiation risk of domestic 16-row mobile CT is significantly lower than imported 8-row mobile CT, enjoying good stability as compared with imported 8-row mobile CT.

Objective:To investigate the effects of ultrasound-guided serratus anterior plane block (SAPB) on hemodynamics in children with microtia undergoing auricular reconstruction.Methods:This research was a prospective randomized control study. Patients were prospectively recruited from March 2022 to July 2022 at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Children with microtia undergoing auricular reconstruction with costal cartilage were randomly included in either a SAPB-pre group(SAPB pre-rib harvest group) or a SAPB-post group(SAPB post-rib harvest group). Both groups of children were anesthetized with combined intravenous and inhalation anesthesia. Anesthesia maintenance was provided with i. v. propofol 4-6 mg·kg -1·h -1 and remifentanil 0.1-0.3 μg·kg -1·min -1, sevoflurane at 1% concentration, and a flow rate of 2.5 L/min. During the operation, bispectral index(BIS) was maintained between 40-60, and alterations in mean arterial pressure (MAP) and heart rate (HR) were <20%, compared to the basic values. During the operation, 1% sevoflurane was inhaled to maintain anesthesia. The fluctuation of BIS, MAP, and HR was adjusted by the intraoperative infusion of remifentanil and propofol. Ultrasound-guided SAPB in the SAPB-pre group was performed by an anesthesiologist after tracheal intubation of general anesthesia. In the SAPB-post group, ultrasound-guided SAPB was performed by the same anesthesiologist before the tracheal catheter was removed at the end of the operation, and the concentration of ropivacaine was 0.25% (3 mg/kg). MAP, HR, and BIS were recorded at each time point of admission, pre-rib harvest, during-rib harvest, post-rib harvest, anesthesia extubation, leaving the room. The consumptions of propofol and remifentanil during the operation were also recorded. Continuous data were presented as Mean±SD. Non-repeated measurement parametric variables were compared using the independent samples t-test. Repeated measurement parametric variables were assessed using repeated measures analysis of variance. The same data at varying time points were compared using Dunnett- t test of multiple comparison procedures. Categorical data were compared using the Chi-square test. Results:Sixty children were randomized to SAPB-pre group and SAPB-post group and 30 in each group. The data of gender (boy 22/ girl 8 vs. boy 23/ girl 7), age[(8.03±1.07)years vs. (8.33±1.16)years], body mass index [(17.46±2.79)kg/m 2 vs. (17.23±2.11)kg/m 2], operation time[(185.33±16.29)min vs. (190.00±16.50)min] and length of costocartilage[(23.13±1.46)cm vs. (23.63±1.27)cm] between the two groups showed no significant differences ( P>0.05). There was no significant difference in MAP, HR and BIS values at the time of pre-rib harvest, during-rib harvest, and post-rib harvest in the SAPB-pre group ( P>0.05). In the SAPB-post group, the fluctuations of MAP, HR and BIS values at the time of pre-rib harvest, during-rib harvest and post-rib harvest were obvious ( P<0.01). The consumptions of propofol and remifentanil during the operation in the SAPB-pre group were significantly less than that in the SAPB-post group[(555.67±150.90)mg vs. (788.50±191.02)mg, P<0.01; (745.33±183.56)μg vs. (1 080.00±247.26)μg, P<0.01]. Conclusion:Ultrasound-guided serratus anterior plane block can stabilize the hemodynamics during auricular reconstruction using costal cartilage and reduce the consumption of general anesthetic.
