Objective:To investigate the effects of cervical plexus block anesthesia combined with general anesthesia on subtotal thyroidectomy in patients with hyperthyroidism and stress response.Methods:A total of 68 patients with hyperthyroidism who underwent subtotal thyroidectomy in Zhangjiagang City Hospital of Traditional Chinese Medicine, Jiangsu Province, from January 2018 to January 2021 were selected as observation subjects, and were divided into control group and observation group according to the random number table method, both of which were 34 cases. Patients in control group were given general anesthesia, and the observation group was given cervical plexus block anesthesia combined with general anesthesia. The heart rate and mean arterial pressure before anesthesia (T0), immediately before intubation (T1), immediately after intubation (T2), and at the end of surgery (T3), the time of awakening and extubation after surgery, the visual analog score (VAS) of pain at 1, 4, 12, and 24 hours after surgery, stress response of before and 24 hours after surgery, and complications after surgery were compared between the two groups.Results:There was no significant difference in heart rate and mean arterial pressure between the two groups at T0 ( P > 0.05); the heart rate and mean arterial pressure at T1 were lower than those at T0 in the same group ( P < 0.05); the heart rate and mean arterial pressure at T2 and T3 in the control group were higher than those at T0 in the same group ( P < 0.05); the heart rate and mean arterial pressure at T2 and T3 in the observation group did not change significantly compared with those at T0 in the same group ( P > 0.05), but were lower than those in the control group at the same time ( P < 0.05). The awakening time and extubation time of patients in the observation group were shorter than those in the control group ( P < 0.001). The VAS scores of patients in the observation group were lower than those in the control group at 4, 12 and 24 hours after surgery ( P < 0.001). The serum norepinephrine (NE) and cortisol (COR) levels of patients in the two groups at 24 hours after surgery were higher than those before surgery, and the levels in the observation group were lower than those in the control group at the same time ( P < 0.05). The total incidence of postoperative complications in the observation group (8.82%, 3/34) was lower than that in the control group (29.41%, 10/34, χ 2 = 4.66, P = 0.031). Conclusion:Cervical plexus block anesthesia combined with general anesthesia has a good effect on subtotal thyroidectomy in patients with hyperthyroidism, which can speed up the patients' awakening, reduce complication, and has little impact on stress response.

Objective: This cross-sectional study aimed to address the relationship between the volume of epicardial adipose tissue (EAT) with cardiovascular risk factors and coronary artery calcification(CAC) in the community residents. Methods: Individuals were recruited from the Jidong Community (Tangshan City, Northern China) which mainly comprised employees of the Jidong Co. Ltd. and their family members. From July 2013 to August 2014, 2 647 participants aged ≥40 years were included in this study. The volume of EAT and coronary artery calcification score (CAC score) were determined by a 64-slice CT. Carotid intima-media thickness (CIMT) was measured by a trained sonographer using a high-resolution B-mode topographic ultrasound system. Venous blood samples were analyzed by automated analyzers in the central laboratory. A validated questionnaire specifically designed for this study was used to collect demographic data from all participants by trained doctors. Characteristics of study cohort were compared according to quartiles of EAT volume (n=660, 663, 662, 662, repectively). Results: (1) The mean age of participants was (55.31±7.76) years and 49.94% (n=1 322) were men. The median EAT volume (interquartile) was 129.42 (95.66, 176.51)cm³. (2) Age, BMI, waist circumference and hip circumference, systolic blood pressure, LDL-C, triglycerides, and fasting blood glucose were significantly higher, while HDL-C level was significantly lower in participants with higher EAT volume than participants with lower EAT volume (all P<0.05). Carotid intima-media thicken (CIMT) and higher CAC score were also significantly higher in participants with higher volume of EAT. Furthermore, percentage of diabetes mellitus, hypertension, hyperlipidemia increased in proportion with increasing EAT volume (P<0.05). (3) In the linear regression, significant positive relations were found for age (β=0.019 3, 95%CI 0.017-0.021, P<0.001), waist circumference (β=0.012 7, 95%CI 0.009-0.016, P<0.001), BMI (β=0.022 4, 95%CI 0.013-0.032, P<0.001), LDL-C (β=0.048 4, 95%CI 0.021-0.076, P<0.001), and HDL-C (β=-0.098 1, 95%CI-0.164--0.032, P<0.001) was inversely related to the EAT volume. (4) Logistic regression analysis indicated that EAT volume was an independent risk factor for CAC score>0 (OR=1.233, 95%CI 1.205-1.262, P<0.001) . Conclusions Our findings indicate that EAT volume is strongly correlated to cardiovascular risk factors and coronary calcification and is an independent risk factor of increased coronary calcification in community residents.

COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.
