Different Anti-inflammatory Drugs on High-Sensitivity C-Reactive Protein in Patients After Percutaneous Coronary Intervention: A Pilot Randomized Clinical Trial.

ABSTRACT: Colchicine reduces atherothrombotic cardiovascular events in coronary artery disease because of its anti-inflammatory effect. However, the effects of the other anti-inflammatory drugs in coronary artery disease remain unclear. This study included 132 patients aged 18-80 years who completed the planned percutaneous coronary interventions and were treated with aggressive secondary prevention strategies for 4 weeks. The subjects were randomly assigned to 1 of the following treatment groups for 4 weeks: (1) control: no additional intervention; (2) colchicine: 0.5 mg once a day; (3) tranilast: 0.1 g thrice a day; or (4) oridonin: 0.5 g thrice a day. The primary outcome was the percentage change in high-sensitivity C-reactive protein (hsCRP) levels at the end of 4 weeks. In total, 109 patients completed the study. The mean age was 58.33 years, 81 (74.31%) were male, and 28 (25.69%) were female. The percentage changes in hsCRP after 4 weeks of treatment were -11.62%, -48.28%, -21.60%, and -7.81%, in the control, colchicine, tranilast, and the oridonin groups, respectively. Compared with the control group, only the colchicine group showed significantly greater reduction in hsCRP levels ( P = 0.022). In targeted proteomic analysis, proteins associated with neutrophil activation (azurocidin, myeloperoxidase, and myeloblastin), platelet aggregation (glycoprotein VI), and endothelial damage (galectin-3) were reduced with colchicine therapy. These results show that of 3 anti-inflammatory drugs only colchicine could reduce hsCRP in patients after percutaneous coronary interventions.

Current status and nurses' perceptions of the electronic tabular nursing records in Henan, China.

AIMS: To survey the types of Electronic Nursing Records used and to explore nurses' perceptions in the hospitals in Henan Province, China. BACKGROUND: There are few studies about status of electronic nursing documents from nurses' view. METHOD: A cross-sectional study of 3,586 nurses using a web-based questionnaire was conducted. RESULTS: Approximately 98% of the nurses were college graduates or had higher degrees, with 46% of the nurses managed more than nine beds per nurse each day. About 27% spent more than two hours daily writing records with a further 38% spending between 1 and 2 hr. However, only 52% realized professional nursing records should be archived and fewer than 80% knew the importance and significance of preserving fundamental nursing records. CONCLUSION: Although nurses' educational level in Henan is high, the younger age of them (i.e., less experience) and heavy workload may lead to inferior quality of ENR. Nurses' awareness of the importance and legal significance of documents needs improvement. IMPLICATION FOR NURSING MANAGEMENT: Our results may provide detailed evidence of the time consuming as well as nurses' knowledge of, abilities in, and opinions about record-keeping in developed countries and bring potential clinical implications for the nursing managers worldwide.

No evidence of coronary plaque stabilization by allopurinol in patients with acute coronary syndrome.

BACKGROUND: Allopurinol, a xanthine inhibitor that lowers uric acid concentration, has been proven to reduce inflammation and oxidative stress in patients with cardiovascular disease. However, it is unknown whether these beneficial effects translate into favorable plaque modification in acute coronary syndromes (ACS). This study aimed to investigate whether allopurinol could improve coronary plaque stabilization using coronary computed tomography angiography (CCTA). METHODS: This was a prospective, single-center, randomized, double-blind clinical trial began in March 2019. A total of 162 ACS patients aged 18-80 years with a blood level of high-sensitivity C-reactive protein (hsCRP) â€‹> â€‹2 â€‹mg/L were included. The subjects were randomly assigned in a 1:1 ratio to receive either allopurinol sustained-release capsules (at a dose of 0.25 â€‹g once daily) or placebo for 12 months. The plaque analysis was performed at CCTA. The primary efficacy endpoint was the change in low-attenuation plaque volume (LAPV) from baseline to the 12-month follow-up. RESULTS: Among 162 patients, 54 in allopurinol group and 51 in placebo group completed the study. The median follow-up duration was 14 months in both groups. Compared with placebo, allopurinol therapy did not significantly alter LAPV (-13.4 â€‹± â€‹3.7 â€‹% vs. -17.8 â€‹± â€‹3.6 â€‹%, p â€‹= â€‹0.390), intermediate attenuation plaque volume (-16.1 â€‹± â€‹3.0 â€‹% vs. -16.2 â€‹± â€‹2.9 â€‹%, p â€‹= â€‹0.992), dense calcified plaque volume (12.2 â€‹± â€‹13.7 â€‹% vs. 9.7 â€‹± â€‹13.0 â€‹%, p â€‹= â€‹0.894), total atheroma volume (-15.2 â€‹± â€‹3.2 â€‹% vs. -16.4 â€‹± â€‹3.1 â€‹%, p â€‹= â€‹0.785), remodeling index (2.0 â€‹± â€‹3.9 â€‹% vs. 5.4 â€‹± â€‹3.8 â€‹%, p â€‹= â€‹0.536) or hsCRP levels (-73.6 [-91.6-17.9] % vs. -81.2 [-95.4-47.7] %, p â€‹= â€‹0.286). CONCLUSIONS: Our findings suggest that allopurinol does not improve atherosclerotic plaque stability or inflammation in ACS.

Research advances in the association between NF-κB signaling pathway and hepatitis C virus infection / 医学研究生学报

The nuclear factor-κB (NF-κB) pathway plays an important role in cell proliferation, survival, early viral response, cytokine secretion, and pro-inflammatory. Hepatitis C virus (HCV) can hijack and interact with the NF-κB signaling pathway and affect disease outcomes. This paper describes the interaction between NF-κB protein family, signaling pathway, HCV viral protein and host NF-κB signaling pathway, and its effect on HCV infection. In the future, further study is expected to be done in this aspect to provide new strategies for the screening of HCV high-susceptibility population as well as prevention.

Effects of CeA lesions on the initiation and expression of sodium appetite in sodium-deficient rats / 中国应用生理学杂志

OBJECTIVE@#To investigate the effects of central nucleus of amygdala (CeA) lesion on the initiation and expression of sodium appetite in sodium-deficient rats.@*METHODS@#Three groups of SD rats (n=6 in each group) were treated with bilateral CeA lesion, sham lesion or no lesion. After the recovery, the rats were fed with low-sodium diets for 14 days to establish a sodium-deficient rat model. The double-bottle selection in single cage test was used to observe the intake of 0.3 mol/L NaCl and DW in 5 timepoint with 24 hours in sodium-deficient rats. Immunofluorescence staining of aldosterone-sensitive neurons in the nucleus tractus solitarii (NTS)was used to investigate the effect of CeA lesion or not on the activity of aldosterone-sensitive neurons in rats with or without sodium deficiency.@*RESULTS@#After fed with low-sodium diet for14 days, the volume and preference rate of 0.3 mol/L NaCl intake of the rats within 24 h were significantly increased compared with those before low-sodium diet (P＜0.01). The intake volume and the preference rate of 0.3 mol/L NaCl in CeA lesion rats were significantly decreased than those in CeA sham lesion rats and normal rats in the sodium-deficient condition (P＜0.01). The CeA lesion had no effects on the activity of aldosterone-sensitive neurons in NTS in rats with low-sodium diet.@*CONCLUSION@#Low-sodium diet induces an increase in the expression of sodium appetite in rats. CeA lesions inhibit the behavioral expression of sodium appetite in sodium-deficient rats but have no effects on the initiation of sodium appetite in rats with sodium-deficient rats.

Progress in the effects of injury and regeneration of gustatory nerves on the taste functions in animals / 生理学报

The sensor of the taste is the taste bud. The signals originated from the taste buds are transmitted to the central nervous system through the gustatory taste nerves. The chorda tympani nerve (innervating the taste buds of the anterior tongue) and glossopharyngeal nerve (innervating the taste buds of the posterior tongue) are the two primary gustatory nerves. The injuries of gustatory nerves cause their innervating taste buds atrophy, degenerate and disappear. The related taste function is also impaired. The impaired taste function can be restored after the gustatory nerves regeneration. The rat model of cross-regeneration of gustatory nerves is an important platform for research in the plasticity of the central nervous system. The animal behavioral responses and the electrophysiological properties of the gustatory nerves have changed a lot after the cross-regeneration of the gustatory nerves. The effects of the injury, regeneration and cross-regeneration of the gustatory nerves on the taste function in the animals will be discussed in this review. The prospective studies on the animal model of cross-regeneration of gustatory nerves are also discussed in this review. The study on the injury, regeneration and cross-regeneration of the gustatory nerves not only benefits the understanding of mechanism for neural plasticity in gustatory nervous system, but also will provide theoretical basis and new ideas for seeking methods and techniques to cure dysgeusia.

A novel high nitrogen nickel-free coronary stents system: evaluation in a porcine model / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To study the safety of the novel high nitrogen nickel-free austenitic stainless steel bare metal stents (BMS) in a recognized porcine coronary model and to select a better grid structure of it.</p><p><b>METHODS</b>Three types of stents were randomly implanted in different coronary arteries of the same pig: 316 L stainless steel BMS (316 L-BMS) (n=12), novel high nitrogen nickel-free stents Grid A (NF-A-BMS) (n=12) and novel high nitrogen nickel-free stents Grid B (NF-B-BMS) (n=12). In total, eighteen animals underwent successful random placement of 36 oversized stents in the coronary arteries. Coronary angiography was performed after 36 d of stents implantation. Nine animals were respectively sacrificed after 14 d and 36 d for histomorphologic analysis.</p><p><b>RESULTS</b>Quantitative coronary angiography (QCA) showed similar luminal loss (LL) in the three groups: (0.21 ± 0.17) mm for 316 L-BMS, (0.16 ± 0.12) mm for NF-A-BMS, (0.24 ± 0.15) mm for NF-B-BMS (P>0.05). Histomorphomeric analysis after 15 d and 36 d revealed that there was also no significant difference among the three groups in neointimal area (NA) with similar injury scores respectively. High magnification histomorphologic examination showed similar inflammation scores in the three groups, but NF-A-BMS group had poorer endothelialization scores compared with NF-B-BMS group, 2.00 ± 0.63 vs. 2.83 ± 0.41 (P=0.015) at 15 d, which also could be proved by the scanning electron microscope. However, the difference could not been observed at 36 d.</p><p><b>CONCLUSION</b>The novel NF-BMS showed similar safety as 316 L-BMS during the short-term study. NF-B-BMS had better endothelialization than NF-A-BMS and this may owe to the specific strut units.</p>
