Blood stasis is the main pathological factor in the occurrence of cardiovascular diseases. Notoginseng Radix et Rhizoma is the representative medicine for activating blood and dissipating stasis. The effective components of panax notoginseng saponins, the active part of Notoginseng Radix et Rhizoma, are ginsenoside Rg1, ginsenoside Rb1, ginsenoside Rd, and notoginsennoside R1, having good intervention effects on cardiovascular diseases, which have become the research hotspots in recent years. This article reviewed the research progress in Notoginseng Radix et Rhizoma and its major saponins in the field of cardiovascular diseases, and provided ideas for clinical prevention and treatment and research and development of medicine.

Objective: To report an investigation of a family cluster of coronavirus disease 2019 ( COVID-19 ) in Ningbo, so as to provide reference for the prevention and control measures. Methods: According to the COVID-19 Prevention and Control Program ( fourth version ) , an epidemiological investigation was conducted to collect the demographic information, clinical features and exposure history, to find the close contacts, and to figure out the source and route of infection. Results: Twelve confirmed cases and one asymptomatic case were reported. The attack rate was 16.05%. Among them, five were males and eight were females; the age ranged from 11 to 85 years old, with a median of 39 years old; most had mild symptoms. The incubation period was 2-13 days, with a median of 6.5 days. The first case ( Case 1 ) developed the symptoms on January 22, and had close contact with Zhang, an asymptomatic case, on January 20. Zhang was related to a cluster in the Buddhist assembly on January 19. Case 1, who caused the spread of the epidemic among family members, participated in several family visits and dinners from January 22 to 27 with other 24 families, resulting in six secondary cases and six third-generation cases. There were 54 close contacts except the family members, no infection was found. Conclusion This family cluster may result from the close contact with an asymptomatic case, and then spread within families through having dinners and living together.

Objective:To explore the clinical characteristics of elderly patients with type 2 diabetes mellitus (T2DM) complicated with coronary atherosclerotic heart disease (CHD) and analyze the risk factors of CHD in patients with T2DM.Methods:Using the method of retrospective cohort study, 406 elderly male patients with T2DM (≥75 years old) admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University from January 2017 to January 2020 were selected and divided into T2DM without CHD group (165 cases) and T2DM with CHD group (241 cases). The clinical characteristics in elderly patients with T2DM complicated with CHD and risk factors for CHD were analyzed.Results:The age ((86.78±5.35 )years old), course of T2DM((12.32±0.46) years), fasting blood glucose(FPG)((7.64±2.81) mmol/L), hemoglobin a1c (HbA1c)((7.59±1.21)%), the proportion of hypertension(84.65%(204/241)), D-dimer((0.50±0.13) mg/L), the incidence of thromboembolic events(46.06%(111/241)), blood serum creatinine ((94.81±12.70) μmol/L), urea nitrogen((8.31±4.46) mmol/L), uric acid((376.44±116.01) μmol/L) in T2DM with CHD group were higher than those in T2DM without CHD((78.51±4.81)years old, (10.66±0.67)years, (6.84±2.19) mmol/L, (7.02±2.15)%, 63.03%(104/165), (0.21±0.04 ) mg/L, 13.33%(22/165), (83.01±14.40) μmol/L, (6.79±2.89) mmol/L, (333.56±95.15) μmol/L ), and the differences were statistically significant( t=15.908, t=2.042, t=3.055, t=3.088, χ 2=23.828, t=5.059, χ 2=42.098, t=2.401, t=4.188, t=4.075; all P<0.05). The total bilirubin(TBil)(8.80(6.60, 11.60) μmol/L), glomerular filtration rate(GFR)((76.49±29.80) mL/(min·1.75 m 2)) in T2DM with CHD group were lower than those in T2DM without CHD group (11.25(8.23, 15.28) μmol/L, (91.81±28.31) mL/(min·1.75 m 2)), the differences were statistically significant( Z=2.304, t=5.126; all P<0.001). The total cholesterol((3.84±0.85) mmol/L), low-density lipoprotein cholesterol(LDL-C)((2.12±0.68 ) mmol/L) in T2DM with CHD group were lower than those in T2DM without CHD group((4.10±1.00) mmol/L, (2.45±0.85) mmol/L), the differences were statistically significant( t=2.828, 4.156; all P<0.05). The rate of starting lipid-lowering and stable plaque treatment in T2DM with CHD group (82.57%(199/261))was higher than that in T2DM without CHD group(42.42%(70/165)), and the difference was statistically significant (χ 2=70.614, P<0.001). Influenced by lipid-lowering therapy, the total cholesterol and LDL-C in T2DM patients with CHD were significantly decreased.Logistic regression analysis showed that age elevated( OR 1.346, 95% CI 1.263-1.434, P<0.001), elevated hemoglobin a1c concentration( OR 1.427, 95% CI 1.140-1.785, P=0.002), complicated with hypertension( OR 3.534, 95% CI 1.684-7.418, P=0.001), elevated D-dimer concentration( OR 3.969, 95% CI 1.227-12.841, P=0.021)and elevated uric acid concentration( OR 1.005, 95% CI 1.001-1.008, P=0.006)were independent risk factors for CHD in elderly male patients with T2DM. Conclusion:Elderly patients with T2DM complicated with CHD are more likely to be in hypercoagulable state, more likely to have thromboembolic events, and more obvious renal function damage.Poor fasting blood glucose control and decreased total bilirubin concentration are the influencing factors of CHD in elderly male patients with T2DM.Age elevated, elevated hemoglobin a1c concentration, complicated with hypertension, elevated D-dimer concentration and elevated uric acid concentration are independent risk factors for CHD in elderly male patients with T2DM.

Objective: To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment. Results: With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05). Conclusion Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.
