BACKGROUND: The optimal apolipoprotein or lipid measures for identifying statin-treated patients with coronary artery disease (CAD) at residual cardiovascular risk remain controversial. This study aimed to compare the predictive powers of apolipoprotein B (apoB), non-high-density lipoprotein cholesterol (non-HDL-C), low-density lipoprotein cholesterol (LDL-C), apoB/apolipoprotein A-1 (apoA-1) and non-HDL-C/HDL-C for myocardial infarction (MI) in CAD patients treated with statins in the setting of secondary prevention. METHODS: The study included 9191 statin-treated CAD patients with a five-year median follow-up. All measures were analyzed as continuous variables and concordance/discordance groups by medians. The hazard ratio (HR) with 95% CI was estimated by Cox proportional hazards regression. Patients were classified by the clinical presentation of CAD for further analysis. RESULTS: The high-apoB-low-LDL-C and the high-non-HDL-C-low-LDL-C categories yielded HR of 1.40 (95% CI: 1.04-1.88) and 1.51 (95% CI: 1.07-2.13) for MI, respectively, whereas discordant high LDL-C with low apoB or non-HDL-C was not associated with the risk of MI. No association of MI with discordant apoB versus non-HDL-C, apoB/apoA-1 versus apoB, non-HDL-C/HDL-C versus non-HDL-C, or apoB/apoA-1 versus non-HDL-C/HDL-C was observed. Similar patterns were found in patients with acute coronary syndrome. In contrast, no association was observed between any concordance/discordance category and the risk of MI in patients with chronic coronary syndrome. CONCLUSIONS ApoB and non-HDL-C better predict MI in statin-treated CAD patients than LDL-C, especially in patients with acute coronary syndrome. ApoB/apoA-1 and non-HDL-C/HDL-C show no superiority to apoB and non-HDL-C for predicting MI.

Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.

Through consulting the ancient herbal and medical books， combined with the field investigation， the name， origin， collection and processing of Dendrobium medicinal materials were researched， which provided a basis for the development of famous classical formulas containing this kind of herbs. Due to the wide distribution of D. officinale， the Dendrobium species represented by D. officinale and D. huoshanense， which are short， fleshy and rich in mucus， should be the most mainstream of Dendrobium medicinal materials in previous dynasties. Compared with Shihu， Muhu with loose texture， long and hollow is born on trees. According to the characteristic description， it should be D. nobile， D. fimbriatum and so on， of which D. nobile was the mainstream. The Chinese meaning of Jinchai was confused in the past dynasties， so it was not suitable to be treated as a plant name. The production areas of Dendrobium medicinal materials in the past dynasties have changed with the discovery of varieties， artificial cultivation and other factors. Lu'an， Anhui province， was the earliest recorded in the Han and Wei dynasties. Since the Tang and Song dynasties， it had been extended to Guangdong and Guangxi， and it was considered that "Dendrobii Caulis in Guangnan was the best". In the Ming dynasty， Sichuan and Zhejiang products were highly praised， and in the Qing dynasty， Huoshan products were highly praised. Dendrobium medicinal materials had been used as medicine by stems in all dynasties. The medicinal materials were divided into fresh products and dry products. The fresh products can be used immediately after removing the sediment from the roots. The dry products need further processing， most of them used wine as auxiliary materials for steaming， simmer to paste or decoction into medicine. D. officinale and D. huoshanense have special processing specifications since the middle of Qing dynasty， that is， "Fengdou". According to the research results， in Ganluyin， the effect of Dendrobium medicinal materials is mainly heat clearing， and D. nobile with bitter taste can be selected. The main effect of Dendrobium medicinal materials in Dihuang Yinzi is tonic， D. officinale or D. huoshanense can be selected.

Objective To investigate the morphological characteristics of Dermatophagoides farinae at different developmental stages. Methods The cultured D. farinae was isolated, and the external morphological features of mites at various developmental stages were observed using scanning electron microscopy (SEM), including egg, larva, nymph and adult stages. Results The D. farinae egg appeared a long oval shape, and the larval mites had three pairs of legs. The nymph had four pairs of legs and underdeveloped genital pores containing genital setae and anal setae, and adult mites appeared long and oval in shape, with decorative patterns on epidermis, and had four pairs of legs. In male adult mites, remarkable thickening of the leg I and thicker and longer leg III than the leg IV were seen, and ventral genital regions were found between the basal segments of legs III and IV; the anus was surrounded by a circular peri-anal ring, with a pair of anal suckers and anal setae within the ring. In the female adult mites, slender legs III and IV with an equal length were seen, and a “λ-shape” genital hole was observed on the ventral surface, with a crescent-like genital plate in the anterior part, and the anus appeared a longitudinal slit. Conclusions An SEM observation of the external morphology of D. farinae provides understandings of the morphological characteristics of D. farinae, which is of great significance for the classification and identification.

Pulmonary hypertension(PH)is a chronic,progressive,high-mortality disease characterized by a continuous increase in pulmonary vascular pressure. All types of PH have the same characteristics,i.e.,the excessive proliferation,anti-apoptosis and inflammation of pulmonary artery endothelial cells and smooth muscle cells,which leads to progressive thickening of pulmonary small vessels,resulting in pulmonary vascular remodeling and increased pulmonary vascular resistance,ultimately leading to right ventricular hypertrophy,heart failure,and death. The drugs used to treat PH mainly include L-type calcium channel blockers,phosphodiesterase 5 inhibitors,guanosine cyclase activators,endothelin receptor antagonists,and synthetic prostacyclin and its analogues. These drugs reduce pulmonary artery pressure by relaxing pulmonary blood vessels but do not cure the patient,and their prognosis remains poor. Therefore,the development of drugs that can effectively improve or even reverse pulmonary vascular remodeling is the key to treating PH. In recent years,studies on pulmonary vascular remodeling mainly included(1)the synthesis of new small-molecule compounds;(2)the transformation of mature drugs,such as the use of drug combinations and dosage form transformation,etc.;(3)the pharmacodynamic evaluation of traditional Chinese medicines and derived compounds based on the theory of "lung distension";(4)research into monomers of traditional Chinese medicine; and(5)research into new targets.

Objective: To analyze factors associated with unplanned revascularization (UR) risk in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). Methods: A total of 10,640 cases with CAD who underwent PCI were analyzed. Multivariate COX regressions and competing risk regressions were applied. Results: The patients who underwent UR following PCI in 30 days, 1, and 2 years accounted for 0.3%, 6.5%, and 8.7%, respectively. After multivariate adjustment, the number of target lesions [hazard ratio ( ) = 2.320; 95% confidence interval ( ): 1.643-3.277; < 0.001], time of procedure ( = 1.006; 95% : 1.001-1.010; = 0.014), body mass index ( = 1.104; 95% : 1.006-1.210; = 0.036), incomplete revascularization (ICR) ( = 2.476; 95% : 1.030-5.952; = 0.043), and age ( 1.037; 95% : 1.000-1.075; = 0.048) were determined as independent risk factors of 30-day UR. Factors, including low-molecular-weight heparin or fondaparinux ( = 0.618; 95% : 0.531-0.719; < 0.001), second-generation durable polymer drug-eluting stent ( 0.713; 95% : 0.624-0.814; < 0.001), left anterior descending artery involvement ( = 0.654; 95% : 0.530-0.807; < 0.001), and age ( = 0.992; 95% : 0.985-0.998; = 0.014), were independently associated with decreased two-year UR risk. While, Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score ( = 1.024; 95% : 1.014-1.033; < 0.001) and ICR ( = 1.549; 95% : 1.290-1.860; < 0.001) were negatively associated with two-year UR risk. Conclusion Specific factors were positively or negatively associated with short- and medium-long-term UR following PCI.

BackgroundThe Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients (PARIS) bleeding score is a novel score for predicting the out-of-hospital bleeding risk after percutaneous coronary intervention (PCI). However, whether this score has the same value in non-European and American populations is unclear. This study aimed to assess the PARIS bleeding score's predictive value of bleeding in patients after PCI in the Chinese population.

MethodsWe performed a prospective, observational study of 10,724 patients who underwent PCI from January to December 2013, in Fuwai Hospital, China. We defined the primary end point as major bleeding (MB) according to Bleeding Academic Research Consortium definition criteria including Type 2, 3, or 5. The predictive value of the PARIS bleeding score was assessed with the area under the receiver operating characteristic (AUROC) curve.

ResultsOf 9782 patients, 245 (2.50%) MB events occurred during the 2 years of follow-up. The PARIS bleeding score was significantly higher in the MB group than that of non-MB group (4.00 [3.00, 5.00] vs. 3.00 [2.00, 5.00], Z = 3.71, P < 0.001). According to risk stratification of the PARIS bleeding score, the bleeding risk in the intermediate- and high-risk groups was 1.50 times (hazard ratio [HR]: 1.50; 95% confidence interval [CI]: 1.160-1.950; P = 0.002) and 2.27 times higher (HR: 2.27; 95% CI: 1.320-3.900; P = 0.003) than that in the low-risk group. The PARIS bleeding score showed a moderate predictive value for MB in the overall population (AUROC: 0.568, 95% CI: 0.532-0.605; P < 0.001) and acute coronary syndrome (ACS) subgroup (AUROC: 0.578, 95% CI: 0.530-0.626; P = 0.001) and tended to be predictive in the non-ACS subgroup (AUROC: 0.556, 95% CI: 0.501-0.611; P = 0.054).

ConclusionThe PARIS bleeding score shows good clinical value for risk stratification and has a significant, but relatively limited, prognostic value for out-of-hospital bleeding in the Chinese population after PCI.

Objective To study the antiviral effect of Jin Qiao Tablets on influenza A H1N1 virus in vivo. Methods The mouse pneumonia model was established by nasal inhalation of 15 LD50 of influenza virus. After prophylactic or therapeutic medication for 5 d,mouse lung tissue was taken out and weighed. Viral load in lung tissue was measured by polymerse chain reaction(PCR),and the level of γ-interferon(γ-IFN)in rat serum and lung was detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA)for evaluating the effect of Jin Qiao Tablets on lung index, viral load and γ-IFN in rats. After prophylactic or therapeutic medication for 7 d,morbidity and mortality within 14 d of mice with pneumonia induced by nasal inhalation of 3 LD50 were observed to evaluate the action of Jin Qiao Tablets for protecting against death and prolonging life span. Results Jin Qiao Tablets markedly decreased the increased lung index,promoted the death-protection rate and life-prolongation rate, decreased viral load, raised the level of γ-IFN in mice (P < 0.05 or P < 0.01). Experimental results in vivo showed that Jin Qiao Tablets had better anti-influenza virus activity than Yinqiao Jiedu Tablets and Lianhua Qingwen Capsules, and the effect of Jin Qiao Tablets was equivalent to that of Tamiflu. The prophylactic effect of Jin Qiao Tablets was stronger than the therapeutic effect, but there was no significant difference between them. Conclusion Jin Qiao Tablets have obvious effect against influenza A H1N1 virus in vivo.
