OBJECTIVE: To evaluate the feasibility and tolerability of metoprolol standard dosing pathway (MSDP) in Chinese patients with acute coronary syndrome (ACS). METHODS: In this multicenter, prospective, open label, single-arm and interventional study that was conducted from February 2018 to April 2019 in fifteen Chinese hospitals. A total of 998 hospitalized patients aged ≥ 18 years and diagnosed with ACS were included. The MSDP was applied to all eligible ACS patients based on the standard treatment recommended by international guidelines. The primary endpoint was the percentage of patients achieving the target dose at discharge (V2). The secondary endpoints included the heart rate and blood pressure at V2 and four weeks after discharge (V4), and percentage of patients experiencing bradycardia (heart rate < 50 beats/min), hypotension (blood pressure < 90/60 mmHg) and transient cardiac dysfunction at V2 and V4. RESULTS: Of the 998 patients, 29.46% of patients achieved the target dose (≥ 95 mg/d) at V2. The total population was divided into two groups: target group (patients achieving the target dose at V2) and non-target group (patients not achieving the target dose at V2). There was significant difference in the reduction of heart rate from baseline to discharge in the two groups (-4.97 ± 11.90 beats/min vs. -2.70 ± 9.47 beats/min, P = 0.034). There was no significant difference in the proportion of bradycardia that occurred in the two groups at V2 (0 vs. 0, P = 1.000) and V4 (0.81% vs. 0.33%, P = 0.715). There was no significant difference in the proportion of hypotension between the two groups at V2 (0.004% vs. 0.004%, P = 1.000) and V4 (0 vs. 0.005%, P = 0.560). No transient cardiac dysfunction occurred in two groups during the study. A total of five adverse events (1.70%) and one serious adverse event (0.34%) were related to the pathway in target group. CONCLUSIONS In Chinese ACS patients, the feasibility and tolerability of the MSDP have been proved to be acceptable.

Coronavirus disease 2019(COVID-19),which is caused by SARS-CoV-2,varies with regard to symptoms and mortality rates among populations.Humoral immunity plays critical roles in SARS-CoV-2 infection and recovery from COVID-19.However,differences in immune responses and clinical features among COVID-19 patients remain largely unknown.Here,we report a database for COVID-19-specific IgG/IgM immune responses and clinical parameters(named COVID-ONE-hi).COVID-ONE-hi is based on the data that contain the IgG/IgM responses to 24 full-length/truncated proteins corresponding to 20 of 28 known SARS-CoV-2 proteins and 199 spike protein peptides against 2360 serum samples collected from 783 COVID-19 patients.In addition,96 clinical parameters for the 2360 serum samples and basic information for the 783 patients are integrated into the database.Furthermore,COVID-ONE-hi provides a dashboard for defining samples and a one-click analysis pipeline for a single group or paired groups.A set of samples of interest is easily defined by adjusting the scale bars of a variety of parameters.After the"START"button is clicked,one can readily obtain a comprehensive analysis report for further interpretation.COVID-ONE-hi is freely available at www.COVID-ONE.cn.

As an important substitute for agarwood, mountain-agarwood, belonging to the family Oleaceae, comes from the root, stem and thick branch of Syringa pinnatifolia, which has a wide range of application in Inner Mongolia, China. It has good clinical efficacy in the use of cardiovascular diseases. However, the formation speed of mountain-agarwood is extremely slow, and its cultivated seedlings have low resin content. Therefore, how to speed up the formation of mountain-agarwood and increase the resin content is a hot research topic in this field. In this work, 16 S rDNA amplicon sequencing method was used to systematically analyze the bacterial communities of different samples of mountain-agarwood. Our data revealed that the samples of mountain-agarwood had more obvious species diversity than the ones of non-mountain-agarwood, especially the wild mountain-agarwood samples. By analysis of bacterial community composition and species abundance, Sphingomonas, Modestobacter and unidentified Cyanobacteria genus were three dominant bacterial genera in all samples. In addition, there are two identified genera of dominant bacteria, namely Actinoplanes and Microbacterium in both wild and cultivated mountain-agarwood, by bacterial community composition and species richness analysis. Meanwhile, Roseomonas was the dominant bacterial genus in both wild and cultivated non-mountain-agarwood samples. Our work could provides basic data for exploring the mechanism of the mountain-agarwood formation, and help to exploit resource of endophytic bacteria reasonably.

Objective To evaluate the interactive effects of fine particulate matter and temperature on non-accidental mortality of residents in Pudong, Shanghai. Methods Daily mortality, air pollutants and meteorological data from Jan 1^st.2016 to Dec 31^st.2017 were collected.Generalized additive Poisson regression models was used to estimate the effects of PM_2.5 pollution on daily mortality, bivariate response surface models and temperature stratified models were applied to examine the interaction of temperature with PM_2.5 on mortality. Results A total of 43 345 non-accidental deaths were included, daily mean PM_2.5 concentration was 39.1 μg/m³, daily mean temperature was 17.7 ℃.A 10 μg/m³ increase in the daily PM_2.5 at lag 1 day was associated with a 0.56%(95%CI:0.11%-1.01%), 0.49%(95%CI:-0.19%-1.18%) and 0.22%(95%CI:-1.14%-1.60%) increase in non-accidental, cardiovascular and respiratory mortality, respectively.Higher risks were identified for males and the older (≥65 years).The effect estimates per 10 μg/m³ increase in PM_2.5 in medium temperature level were 0.59%(95%CI:0.04%-1.14%)for non-accidental, 0.51%(95%CI:-0.32%-1.35%)for cardiovascular and 0.51%(95%CI:-0.32%-1.35%) for respiratory mortalities.The PM_2.5 effects were approximately 2-4 times higher in higher temperature level for non-accidental and cardiovascular mortalities compared with other temperature levels; for respiratory mortality, the PM_2.5 effects was approximately 2-fold higher in lower temperature levels than the medium, although the interactions between temperature and PM_2.5 were statistically insignificant. Conclusions Temperature may modify the effects of PM_2.5 on mortality in Pudong, Shanghai and the interactive pattern may be different across disease-specific mortalities.

BACKGROUND: Albuvirtide is a once-weekly injectable human immunodeficiency virus (HIV)-1 fusion inhibitor. We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs. METHODS: We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China. Adults on the World Health Organization (WHO)-recommended first-line treatment for >6 months with a plasma viral load >1000 copies/mL were enrolled and randomly assigned (1:1) to receive albuvirtide (once weekly) plus ritonavir-boosted lopinavir (ABT group) or the WHO-recommended second-line treatment (NRTI group). The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks. Non-inferiority was prespecified with a margin of 12%. RESULTS: At the time of analysis, week 24 data were available for 83 and 92 patients, and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups, respectively. At 48 weeks, 80.4% of patients in the ABT group and 66.0% of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL, meeting the criteria for non-inferiority. For the per-protocol population, the superiority of albuvirtide over NRTI was demonstrated. The frequency of grade 3 to 4 adverse events was similar in the two groups; the most common adverse events were diarrhea, upper respiratory tract infections, and grade 3 to 4 increases in triglyceride concentration. Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group. CONCLUSIONS: The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug. This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.

Schistosomiasis was once heavily endemic in Jiangsu Province. Following the control efforts for several decades, schistosomiasis was almost eradicated in all endemic counties in Jiangsu Province in 1980, and transmission control was achieved in the province in 2011. According to the principle of “implementing the control measures with adaptation to local circumstances and guiding the control programs with classified interventions”, an integrated strategy with emphasis on the management of both infectious sources and snails has been recently employed for schitsosomiasis control in Jiangsu Province. In addition, a sensitive and highly effective surveillance system has been built and the application of novel techniques and information construction has been intensified to effectively interrupt the transmission of schistosomiasis in the Province. Transmission interruption of schistosomiasis was achieved in all endemic counties in Jiangsu Province. The paper summarizes the endemic situation of schistosomiasis, progress of schistosomiasis control, and major schistosomiasis control measures implemented during the stage of transmission interruption in Jiangsu Province.

Fluoxetine, an anti-depressant drug, has recently been shown to provide neuroprotection in central nervous system injury, but its roles in subarachnoid hemorrhage (SAH) remain unclear. In this study, we aimed to evaluate whether fluoxetine attenuates early brain injury (EBI) after SAH. We demonstrated that intraperitoneal injection of fluoxetine (10 mg/kg per day) significantly attenuated brain edema and blood-brain barrier (BBB) disruption, microglial activation, and neuronal apoptosis in EBI after experimental SAH, as evidenced by the reduction of brain water content and Evans blue dye extravasation, prevention of disruption of the tight junction proteins zonula occludens-1, claudin-5, and occludin, a decrease of cells staining positive for Iba-1, ED-1, and TUNEL and a decline in IL-1β, IL-6, TNF-α, MDA, 3-nitrotyrosine, and 8-OHDG levels. Moreover, fluoxetine significantly improved the neurological deficits of EBI and long-term sensorimotor behavioral deficits following SAH in a rat model. These results indicated that fluoxetine has a neuroprotective effect after experimental SAH.

Objective To explore the relationship between microelement intake and metabolic syndrome (MS) in elderly males and females in Zhejiang province. Methods Non-parametric Kruskal-Wallis tests were used to compare the intake of microelements by sex among different groups according to the diagnostic criteria of MS in 780 people(404 male,376 female).Logistic regression was used to explore the association between microelements and MS and its components.Results The percentages of inadequate intake of Mn,Zn and Se were relatively high among elderly people of Zhejiang province(males:30.45%,72.52%,75.74%;females:47.34%,33.78%,80.59%,respectively).Microelement intake in males were higher than females(P<0.05).The intake of Fe and Se were higher in the abdominal obesity group than the non-abdominal obesity group among elderly males,the intakes of Fe,Zn,Se in hypertension group were lower, and Se intake was higher in hyperglycemia and hypertriglyceridemia groups. Furthermore, enough intake of Fe(odds ratio OR,0.41;95% confidence interval CI:0.19,0.87)and Se(OR,0.30;95% CI:0.14, 0.63)decreased the risk of hypertension,and high Cu(OR,2.35;95% CI:1.18,4.71)intake increased the risk of hyperglycemia.Among females,Zn intake in the MS group was lower than in the non-MS group;the intakes of Cu, Zn and Se in the hypertension group were lower; the intakes of Fe, Mn and Zn in the hyperglycemia group were lower as well;and Se intake was lower in the low HDL-C group.Again,the high intake of Zn (OR, 3.21; 95% CI: 1.36, 7.59) and Se (OR, 2.79; 95% CI: 1.24, 6.27) increased the risk of abdominal obesity, but moderate intake of Cu (OR, 0.37; 95% CI: 0.19, 0.72) had a protective effect on hypertension. Conclusions The percentages of inadequate microelement intake were relatively high in elderly people of Zhejiang province. There is a relationship between dietary microelements and MS or its components. It is necessary to guide elderly people to adopt reasonable diet by referring to the Chinese dietary reference intake and Dietay Guidelines in order to improve the situation of microelements intake and promote health.

Objective:To observe the effect of electroacupuncture (EA) on the expressions of acetylcholine (ACh) and mucin 5AC (MUC5AC) in the lungs of rats with chronic obstructive pulmonary disease (COPD),and explore the mechanism of EA in treating COPD.Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a control group,a COPD group,and an EA group,with 10 rats in each group.The control group was a group of normal rats.The COPD rat model was induced by cigarette smoke combined with lipopolysaccharide (LPS).The COPD rats were treated with EA at bilateral Feishu (BL 13) and Zusanli (ST 36) in the EA group,30 min each time,once a day,successively for 14 d.The lung function was tested.The contents of ACh and MUC5AC in lungs and bronchoalveolar lavage fluid (BALF) were detected by enzyme-linked immunosorbent assay (ELISA).Pearson method was used to analyze the correlation between pulmonary function and the content of MUC5AC in lungs.The mRNA and protein expressions of MUC5AC in lung tissues were detected by real-time polymerase chain reaction (RT-PCR) and Western blot (WB),respectively.The immune response of MUC5AC was observed by immunohistochemistry.Results:Eight rats were left in each group,and the other two died.Compared with the control group,the total airway resistance (Raw) increased significantly and dynamic compliance (Cdyn) decreased significantly in the COPD group (P＜0.01);compared with the COPD group,the Raw level declined significantly and Cdyn increased significantly in the EA group (P＜0.01).The contents of ACh and MUC5AC in the lungs and BALF were remarkably higher in the COPD group compared with those in the control group (P＜0.01,P＜0.001);compared with the COPD group,the contents of ACh and MUC5AC were significantly lower in the EA group (P＜0.05,P＜0.001).There was a negative correlation between MUC5AC content and lung function (P＜0.001).The mRNA and protein expressions of MUC5AC in the lungs were significantly higher in the COPD group than in the control group (P＜0.001);compared with the COPD group,the expressions were significantly lower in the EA group (P＜0.01).Compared with the control group,the immune response of MUC5AC in the airway epithelium significantly increased in the COPD group (P＜0.001);the immune response of MUC5AC was significantly lower in the EA group compared with that in the COPD group (P＜0.001).Conclusion:EA treatment can improve the lung function of COPD rats,which may be related to its effect in the down-regulation of ACh and MUC5AC contents in the lungs as well as the inhibition of mucus hypersecretion.
