Objective:To compare the prevalence and progression of subclinical atherosclerosis (SA) in populations with different cardiovascular disease (CVD) risks in China, and clarify the relationship between CVD risk stratification and SA.Methods:All participants were from Beijing Community-Based Cohort of Atherosclerosis. A total of 1 462 participants underwent carotid ultrasound and coronary computed tomography scan during 2008-2009 and 2013-2014. After excluding 191 participants with history of CVD and incomplete baseline data, 1 271 participants were included in final analysis. The 10-year CVD risk for participants were calculated based on the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) equation, and risk stratification was performed. The prevalence and progression of SA was determined by carotid intima-media thickness (cIMT), carotid plaque score and coronary artery calcification (CAC) score.Results:In the participants included in this study, 536 (42.2%), 418 (32.9%) and 317 (24.9%) were classified to have low, intermediate and high 10-year risk, respectively. With the rising level of 10-year risk, the proportion of patients with SA and SA progression increased. In low, intermediate and high CVD risk groups, the proportions of participants with CAC were 16.4%, 36.4% and 52.0% (trend P<0.001); and 15.4%, 36.4% and 53.6% had progression of CAC during follow-up, respectively (trend P<0.001); compared with low-risk group, RRs for CAC progression of intermediate and high-risk groups were 2.316 (95% CI: 1.714-3.129) and 3.322 (95% CI: 2.472-4.463), respectively (trend P<0.001). The trend of relationship between CVD risk stratification and cIMT and carotid plaque progression were consistent with CAC. Conclusions:This current study shows CVD risk stratification is closely related to the prevalence and progression of atherosclerosis in Chinese population. However, many people with low CVD risk have atherosclerotic change in their carotid and coronary artery.

Guillain-Barre syndrome rarely develops after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and only a few reports exist in China. Guillain-Barre syndrome is an acute and life-threatening condition that requires early diagnosis and treatment. A patient with acute myeloid leukemia underwent allogeneic HSCT for >5 months and gradually developed limb muscle weakness and limited eye movement after coexisting with delayed acute intestinal graft-versus-host disease. After the examination of cerebrospinal fluid and electromyography, the diagnosis of Guillain–Barre syndrome was confirmed. After a high-dose intravenous immunoglobulin (IVIg) treatment, muscle strength gradually recovered, and the prognosis was good.

BACKGROUND:
Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps.
METHODS:
A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis.
RESULTS:
During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed.
CONCLUSIONS
ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

OBJECTIVE:
To observe the effect of electroacupuncture (EA) at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) on mental state, visceral sensitivity and protein expression of nerve growth factor (NGF), tyrosine kinase receptor A (TrkA) and transient receptor potential vanilloid 1 (TRPV1) of colonic tissue in diarrhea-predominant irritable bowel syndrome (IBS-D) rats, and to explore its possible mechanism on treating IBS-D.
METHODS:
A total of 36 male SD rats of SPF grade were randomized into a blank group, a model group, an EA group and a western medication group, 9 rats in each group. In the model group, the EA group and the western medication group, IBS-D model was established by enema of dinitrobenzene sulfonic acid (DNBS) combined with chronic restraint stress method. In the EA group, EA was applied at "Tianshu" (ST 25) and "Shangjuxu" (ST 37), with disperse-dense wave, in frequency of 2 Hz/100 Hz, 20 min each time, once a day for 7 days. In the western medication group, pinaverium bromide suspension was given by gavage (15 mg•kg-1•d-1) for 7 days. Before and after model establishment, and after intervention, the body mass, 24 h food intake and fecal water content were observed, the visceral sensitivity was detected by abdominal withdrawal reflex (AWR); after intervention, the mental state was evaluated by elevated plus maze (EPM) test, the protein expression of NGF, TrkA and TRPV1 was detected by immunohistochemistry and Western blot in the 4 groups.
RESULTS:
After model establishment, compared with the blank group, the body mass and 24 h food intake were decreased (P<0.05), first systolic latency of AWR was shortened and number of contraction wave of AWR was increased (P<0.05), and fecal water content was increased (P<0.05) in the model group, the EA group and the western medication group. After intervention, compared with the blank group, open arm residence time ratio (OT%) of EPM was decreased (P<0.05) and protein expression of NGF, TrkA, TRPV1 in colonic tissue was increased in the model group (P<0.05); compared with the model group, the body mass and 24 h food intake were increased (P<0.05), first systolic latency of AWR was lengthened and number of contraction wave of AWR was decreased (P<0.05), the fecal water content was decreased (P<0.05), OT% of EPM was increased (P<0.05), and protein expression of NGF, TrkA, TRPV1 in colonic tissue was decreased (P<0.05) in the EA group and the western medication group.
CONCLUSION
Electroacupuncture at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) can relieve the anxiety and depression-like behaviors in IBS-D rats, down-regulate the protein expression of NGF, TrkA, TRPV1 in colonic tissue, so as to reduce the visceral sensitivity and relieve symptoms.

Objective:To explore the differences of risk stratification of very high-risk or extreme high-risk atherosclerotic cardiovascular diseases (ASCVD) and the attainment rates of low-density lipoprotein cholesterol (LDL-C) management targets evaluated by three different criteria, and the causal attributions of these differences.Methods:Patients with ASCVD were consecutively enrolled from January 1 to December 31 in 2019, and were evaluated for very high-risk or extreme high-risk and LDL-C goal attainment rates with 2018 American guideline on the management of blood cholesterol (2018AG), 2019 China Cholesterol Education Program (CCEP) Expert Advice for the management of dyslipidemias (2019EA) and 2020 Chinese expert consensus on lipid management of very high-risk ASCVD patients(2020EC), respectively. The causal attributions of the differences in attainment rates were analyzed as well.Results:A total of 1 864 ASCVD patients were included in this study. According to 2018AG, 2019EA and 2020EC, the proportions of the patients with very high-risk or extreme high-risk were 59.4%, 90.7%, and 65.6%, respectively. The absolute LDL-C target attainment rates were 37.2%, 15.7%, and 13.7%, respectively, the differences between each two rates were statistically significant (all P<0.001). As to the differences in attainment rates between 2020EC and 2018AG, 61.5% were due to the different LDL-C goal attainment values and 38.5% were caused by the different risk stratifications, while for the differences between 2020EC and 2019EA attainment rates, different LDL-C goal attainment values were responsible for 13.2%, and different risk stratifications were responsible for 86.8% of the differences. Conclusions:There are significant differences in the proportions and LDL-C attainment rates among the three different criteria for very high-risk or extreme high-risk ASCVD. 2020EC showed a moderate proportion of patients with extreme high-risk, and had the lowest LDL-C attainment rate. The differences between 2020EC and 2018AG are mainly due to the LDL-C target values, and the differences between 2020EC and 2019EA are mainly caused by the risk stratifications.
