Promoting the construction of a “Healthy China” is essential to building a great modern socialist country. Health workers in every era have their historical missions and they are the “benevolent doctors” of their own era. Therefore， clarifying the basic connotation and times requirements of “benevolent doctors” has become the first question to be answered in cultivating “benevolent doctors”. The basic connotation of “benevolent doctor” should reflect not only the comprehensive development of moral， intellectual， physical， aesthetic， and labor education in fostering virtue and nurturing talents， but also embody the people-centered development philosophy， promote social equity and justice， and reflect the strategic needs of building a “Healthy China.” Specifically in the practice of medical education， emphasizing both medical science spirit and medical humanities spirit has become an important path to cultivate “benevolent doctors” in the new era.

Objective:To investigate the prevalence and associated risk of cardiovascular event of resistant hypertension in treated outpatients.Methods:This study was a nationwide multi-center prospective cohort study. The participants were treated outpatients enrolled in the China Nationwide Ambulatory and Home Blood Pressure Registry study of 42 hospitals in 19 provinces across the country from August 2009 to October 2017. Apparent resistant hypertension was defined as uncontrolled office blood pressure (≥140/90 mmHg, 1 mmHg=0.133 kPa) in spite of the use of three antihypertensive drugs or controlled office blood pressure (<140/90 mmHg) with four antihypertensive drugs or more. Subjects diagnosed with uncontrolled office blood pressure were further subdivided as pseudo-resistant hypertension and true resistant hypertension based on 24 h ambulatory blood pressure monitoring. The primary endpoint was fatal and non-fatal cardiovascular and cerebrovascular events, which was a composite endpoint consisting of cardiovascular and cerebrovascular death, ischemic and hemorrhagic stroke, myocardial infarction, coronary artery revascularization, unstable angina, heart failure, and coronary artery stenosis≥50% confirmed by coronary angiography. Secondary outcomes included fatal and non-fatal stroke or cardiac events. Patients with controlled office blood pressure after taking only 1 or 2 antihypertensive drugs were included as control. Kaplan-Meier survival curves, log-rank test, and Cox proportional risk model were used to evaluate the risk of apparent refractory hypertension in relation to cardiovascular and cerebrovascular prognosis.Results:A total of 2 782 treated hypertensive patients, aged (58.1±12.3) years were enrolled, including 1 403 (50.4%) men. The prevalence of apparent and true resistant hypertension was 15.1% (420/2 782) and 10.5% (293/2 782), respectively. Among patients with apparent resistant hypertension, during a median of 5 years follow-up, the cumulative incidence rate was 28.2, 11.2 and 19.1 per 1 000 person-years for fatal and non-fatal cardiovascular events ( n=58), stroke ( n=24) and cardiac events ( n=40), respectively. The Kaplan-Meier curve and log-rank test showed that those patients with true resistant hypertension, had the highest cumulative incidence rate of fatal and non-fatal cardiovascular events, stroke, and cardiac events. Multivariable Cox regression analyses showed that true resistant hypertension was associated with a significantly higher risk of fatal and non-fatal cardiovascular events ( HR=1.73, 95% CI 1.17-2.56, P=0.006) and stroke ( HR=2.81, 95% CI 1.53-5.17, P=0.001). Conclusion:Resistant hypertension, especially true resistant hypertension, is associated with a higher risk of fatal and non-fatal cardiac and cerebrovascular events.

Objective:To investigate the efficacy and safety of sindilizumab combined with apatinib in the treatment of elderly patients with advanced recurrent and metastatic esophageal squamous cell carcinoma.Methods:A total of 74 elderly patients with recurrent and metastatic esophageal squamous cell carcinoma who were admitted to Xuancheng City Central Hospital from March 2019 to August 2020 were selected, and they were divided into study group and control group by random number table method, with 37 cases in each group. The control group was treated with apatinib mesylate, and the study group was treated with sindilizumab combined with apatinib mesylate. All patients were treated for 2 cycles and followed up for 1 year. The efficacy, peripheral blood tumor marker levels, adverse reactions and survival were compared between the two groups.Results:The objective response rate and clinical control rate in the study group were higher than those in the control group [35.1% (13/37) vs. 13.5% (5/37), 67.6% (25/37) vs. 43.2% (16/37)], and the differences were statistically significant ( χ2 = 4.70, P = 0.030; χ2 = 4.43, P = 0.035). After treatment, the levels of carcinoembryonic antigen (CEA), squamous cell carcinoma-associated antigen (SCC-Ag) and cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) in the two groups were all lower than those before treatment (all P < 0.05); the levels of CEA, SCC-Ag and CYFRA21-1 in the study group were lower than those in the control group (all P < 0.05). There were no differences in the incidence rates of fatigue, proteinuria, bone marrow suppression, and hand-foot syndrome between the two groups (all P > 0.05). After 1 year of follow-up, 20 patients in the study group survived, and the 1-year overall survival (OS) rate was 54.1%; 10 patients in the control group survived, and the 1-year OS rate was 28.6%; the difference in OS between the two groups was statistically significant ( χ2 = 4.06, P = 0.044). Conclusions:Sintilimab combined with apatinib has a good efficacy in the treatment of elderly patients with advanced recurrent and metastatic esophageal squamous cell carcinoma. This regimen can reduce the levels of tumor markers, improve the short-term survival rate of patients, and has good safety.

Objective:To explore the diagnosis process and treatment experience of severe coronavirus disease 2019 (COVID-19) patients with heparin resistance (HR).Methods:The medical team of the First People's Hospital of Lianyungang admitted 2 severe COVID-19 patients with HR in intensive care unit (ICU) during their support to the designated hospital for the treatment of COVID-19 patients in Lianyungang City in November 2021. The clinical features, laboratory examinations, imaging features, treatment and prognosis of the two patients were analyzed.Results:Both severe COVID-19 patients received mechanical ventilation, 1 patient was treated with extracorporeal membrane oxygenation (ECMO) support. Both patients were complicated with lower extremity deep venous thrombosis and HR phenomenon under routine dose anticoagulant therapy. The maximum daily dose of unfractionated heparin exceeded 35 000 U (up to 43 200 U), the 2 patients failed to meet the standard of anticoagulation treatment, and the course of disease was prolonged. After that, argatroban was given 0.4 μg·kg -1·min -1 combined with anticoagulant therapy, the activated partial thromboplastin time (APTT) of patients undergoing ECMO could be maintained at 55-60 seconds and the activated coagulation time (ACT) of them could be maintained at 180-200 seconds. After ECMO support or later sequential mechanical ventilation, both patients recovered and were discharged, and deep venous thrombosis was also effectively controlled. Conclusion:HR phenomenon often occurs during the treatment of severe COVID-19 patients, the anticoagulation regimen should be adjusted in time, and the anticoagulation effect combined with argatroban is clear.

Ambulatory blood pressure monitoring (ABPM) has become indispensable in the current management of hypertension. ABPM is particularly useful in the accurate diagnosis of hypertension. Its diagnostic thresholds had been recently established based on hard clinical outcomes. Cross-classification of patients according to office and ambulatory blood pressure identifies white-coat, masked, and sustained hypertension. ABPM is also useful in cardiovascular (CV) risk assessment. It provides information on daytime and nighttime blood pressure and circadian rhythm, particularly nighttime blood pressure dipping. Nighttime blood pressure is predictive of CV risk independent of office and daytime blood pressure. Isolated nocturnal hypertension is a special form of masked hypertension, with normal daytime but elevated nocturnal blood pressure. It also helps in the evaluation of blood pressure fluctuation and variation, such as morning blood pressure surge and reading-to-reading blood pressure variability. ABPM may derive several other indexes, such as ambulatory blood pressure index and salt sensitivity index, which may be useful in CV evaluations.

Objective:To explore the safety and efficacy of ultrasound-assisted facial filler injection, based on the anatomy of facial vessels to prevent intravascular embolization.Methods:From Jan. 2019 to Sep. 2020, 142 patients were treated with facial soft-tissue filler injection (mean age, 39.7 years; 131 female and 11 male). According to the patients＇ own will, autologous fat or hyaluronic acid was applied respectively. When injecting, the assistant could press over the periorbital artery to temporarily occlude the artery, confirmed with Doppler ultrasound, thus reduced the risk of intravascular embolization, and carefully injected with minimal pressure and tiny amount.Results:A total of 142 patients were enrolled in the study, and 54 patients were treated with autologous fat grafting, while 88 patients were injected with hyaluronic acid. The injection sites included forehead, temple, glabella, nasal root, tear trough, nasolabial fold, cheek, chin, and lips. Facial rejuvenation improvement was satisfied with a smooth contour and proper augmentation. No vascular embolization occurred. 9 patients received a second or third round fat grafting to achieve better outcome. Follow-up duration ranged from 1 month to 6 months.Conclusions:With ultrasound assistant, digital pressure over the orbital artery could temporarily occlude the artery and may reduce the risk of intravascular embolization. The simple technique may add a significant benefit with no additional cost or risk to the patients.

Objective:To evaluate the clinical efficacy of Sini-Jia-Huanglian Decoction on chronic heart failure (CHF) with qi deficiency and blood stasis syndrome. Methods:A total of 100 patients with CHF and qi deficiency and blood stasis syndrome in Handan Mingren hospital from January 2018 to June 2019 who met the inclusion criteria were divided into two groups according to the random number table method, 50 cases in each group. The control group was treated with conventional western medicine therapy, and the treatment group was treated with Sini-Jia-Huanglian Decoction on the basis of the control group. Both groups were treated for 30 days. TCM syndrome score was performed before and after treatment. The level of N-terminal-pro-B-type natriuretic peptide (NT-proBNP) was detected by radioimmunoassay. The levels of peptide and galectin 3 (Gal-3) were detected by ELISA. The exercise tolerance was measured by 6-minute walking test, the clinical efficacy was tevaluated. Results:The total effective rate of the treatment group was 92.0% (46/50), and the control group was 76.0% (38/50), there was significant difference between the two groups ( χ2=4.762, P=0.029). After treatment, the scores of shortness of breath, palpitation, dyspnea, dizziness, chest pain and total scores in the treatment group were significantly lower than those in the control group ( t values were 4.257, 8.493, 8.211, 4.481, 5.500, 6.977, respectively, all Ps<0.01). After treatment, the levels of NT-proBNP (2 349.61 ± 683.50 ng/L vs. 3 026.27 ± 714.35 ng/L, t=4.840), and peptide (12.16 ± 3.43 ng/L vs. 17.52 ± 3.98 ng/L, t=7.214) and Gal-3 (3.01 ± 0.82 μg/L vs. 3.94 ± 0.93 μg/L, t=5.304) in the treatment group were significantly lower than those in the control group ( P<0.01), and the walking distance of 6 minutes (450.66 ± 79.25 m vs. 384.49 ± 70.16 m, t=4.421) was significantly longer than that of the control group ( P<0.01). Conclusions:The Sini-Jia-Huanglian Decoction can improve the heart function and clinical symptoms of CHF patients with qi deficiency and blood stasis syndrome, and improve the clinical efficacy.

Objective:To explore the clinical characteristics and outcomes of pediatric kidney transplantations at a single center and discuss the related clinical issues.Methods:From January 1990 to October 2019, clinical data were analyzed retrospectively for 244 pediatric renal transplants. The youngest recipient was aged 1.8 years and the median age of pediatric recipients was 12.2 years. The major disease was primary or hereditary glomerulonephritis ( n=160, 69.0%), congenital anomalies of kidney and urinary tract (CAKUT), cystic renopathy and other hereditary nephropathies ( n=55, 23.7%). The donor sources included traditional deceased donor ( n=42, 17.2%), living-related donor ( n=19, 7.8%) and organ donation ( n=183, 75.0%). The median age of donors was 2 years (0-51) and the median weight 12.0(2.7-72.0) kg. From January 2013 to October 2019, 170 cases), the major induction immunosuppression regimen was anti-thymocyte globulin (ATG) ( n=110, 64.7%) or basiliximab ( n=58, 34.1%). The maintenance regimen was tacrolimus + mycophenolic acid (MPA) + glucocorticosteroids. Finally the outcomes and the complications were analyzed. Results:The survival rates of 244 kidney allograft recipients were 98.1%, 94.5% and 93.4% and the graft survival rates 92.6%, 84.2% and 82.0% at 1/3/5 years respectively. Ten recipients died of accident ( n=2, 20.0%), pneumonia after transplantation ( n=2, 20.0%) and intracranial hemorrhage ( n=2, 20.0%). Thirty-three recipients lost their allografts mainly due to intravascular thrombosis in graft ( n=5, 14.3%), acute rejection ( n=5, 14.3%) and death ( n=9, 25.7%). Besides, among 109 deceased donor allograft recipients, the postoperative outcomes were delayed graft function recovery (DGF) ( n=27, 24.8%), arterial thrombosis ( n=6, 5.5%), venous thrombosis ( n=1, 0.9%), graft perirenal hematoma ( n=6, 5.5%), raft artery stenosis ( n=10, 9.2%) and graft ureteral fistula ( n=1, 0.9%). The incidence of acute rejection was 17.5% and 23.2% at 1/3 year respectively. The recurrent rate of primary disease was 6.9%, including primary FSGS ( n=3, 42.9%) and IgA nephropathy ( n=2, 28.6%). At 1/3 year post-operation, the incidence of pulmonary infection was 16.9% and 22.4% and the incidence of urinary tract infection 26.9% and 31.7%. Excluding recipients with graft failure, the estimated glomerular filtration rate (eGFR) at 1/2/3 year postoperatively was (80.3±25.2), (81.4±27.8) and (71.8±27.6) ml/(min·1.73 m 2)respectively. Conclusions:The outcomes of pediatric renal transplantations are excellent at our center. Future efforts shall be devoted to optimizing the strategies of donor kidney selection and strengthening preoperative evaluations, perioperative and postoperative managements for improving the long-term outcomes of pediatric renal transplantations.

Objective To explore the impact of glucocorticoid on coagulation through administrating on rats with smoke inhalation.Methods Totally 150 male S-D rats were randomly (random number) divided into 5 groups:control group (ambient air inhalation),smoke group (smoke inhalation for 30 min),smoke+high dosage methyl prednisolone group(MP 40 mg/kg,intraperitoneal injection,s+HMP group),smoke+medium dosage MP (4 mg/kg) group (s+MMP group),smoke+low dosage MP (0.4 mg/kg) group (s+LMP group) (all n=30).Survival rates were calculated 24 h after smoke inhalation.Lung tissues were collected for histopathology and wet to dry (W/D) ratio.Arterial blood was collected for blood gas test.Coagulation factors in lung and plasma were tested.Results Survival rates of three MP groups were markedly improved compared with the smoke group (all P＜0.05),and was significantly higher in the medium dosage group(85.17％) than those in the low and high dosage groups (65.73％ and 60.07％,all P＜0.05).The W/D ratio and blood gas test were markedly improved in the high and medium groups (all P＜0.05).Tissue factor (TF) and thrombin-antithrombin complex (TAT-c) in bronchoalveolar lavage fluid (BALF) increased dramatically after SI (P＜0.01,P=0.005) with a remarkable drop of factor Ⅱ (F Ⅱ) (P=0.007),all of which were attenuated by MP with dosage dependence.The mRNA expression of TF increased dramatically after SI and recovered significantly with MP administration,while the expression of thrombomodulin (TM) recovered in the opposite direction with MP,all of which were in a dosage dependent manner.TF,fibrinogen (FIB),TAT-c increased significantly in plasma after smoke inhalation (P＜0.01,P=0.027,P=0.005).F Ⅷ ％ increased with MP administration and TF was raised by high dosage MP compared with the smoke group.FIB and TAT-c were decreased in all MP groups,which were significant higher in the high and middle dosage groups.The change of TM and endothelial cell protein C receptor (EPCR) in circulation were similar with FIB or TAT-c with or without MP.Protein C (PC％) and antithrombin (AT Ⅲ ％) dropped dramatically after SI,high and middle dosages of MP could restore the activity significantly,while low dosage would restore AT Ⅲ ％ but not PC％.Conclusions Glucocorticoid can significantly improve local and systemical coagulation disorder caused by smoke inhalation,and high-and medium-dosage hormones are effective.The regulation of hormones on the coagulation system is an important mechanism in the treatment of smoke inhalation induced lung injury.
