Abstract To observe the influence of thalidomide on tumor necrosis factor-a (TNF-α) of spontaneous type-2 diabetes rat (kk-Ay rat) model, and to explore the clinical value of TNF-a mediated inflammation approach to improve the injury on epithelial cell of kidney tubules. There are 30 kk-Ay rates being chosen to establish the Diabetic Nephropathy model and divided into thalidomide group and the model control group, 15 pieces for each group respectively. The levels of TNF-α, IL-1β, interleukin -6 (IL-6) and interleukin -18 (IL-18) of kk-Ay in the thalidomide group and the model control group were both at a higher level before treatment, but the difference was not statistically significant (P >0.05); The levels of TNF-α, IL-1β, interleukin -6 (IL-6) and interleukin -18 (IL-18) in kk-Ay rats 8/10/12 weeks after the treatment in the thalidomide group were significantly decreased, with statistically significant differences compared with the model control group (P < 0.05). The histopathological changes of kidney tubules epithelial cell injury on rats were observed through dissection. Thalidomide will effectively lower TNF-α and IL-1β expression levels in kk-Ay rat models, reduce inflammatory response, and thus improve damage on kidney tubules epithelial cell, which is worthy of further exploration and application.

Abstract To standardize the tea export market and guarantee the interest of consumers, the adulteration problem in Taiping Houkui tea should be eliminated. In this study, a screening scheme comprising chemometrics and statistical analysis was proposed to estimate the geographical origin of Taiping Houkui tea. A total of 11 metal ions in Taiping Houkui tea were detected by performing a chemometric experiment. The key variables that can be used to identify the geographical origin of Taiping Houkui tea were screened using the least absolute shrinkage and selection operator method (LASSO). The statistical significance of selected key variables was also tested by analysis of variance (ANOVA), which confirmed the effectiveness of the LASSO. The proposed strategy was verified by the experimental testing and has great potential for determining the geographical origin of green tea.

Resumo Fundamento A dupla antiagregação plaquetária (DAP) é o tratamento fundamental do infarto agudo do miocárdio (IAM). Objetivo O presente estudo visou investigar a eficácia e a segurança da tripla antiagregação plaquetária (TAP) em pacientes femininas idosas com diabetes e infarto agudo do miocárdio com supradesnível do segmento ST (IAMCSST), que foram submetidas à intervenção coronária percutânea ICP. Métodos Trata-se se de um estudo randomizado e mono-cego. O grupo controle A (97 pacientes idosos do sexo masculino com diabetes e STEMI, cujos escores CRUSADE foram < 30) recebeu aspirina, ticagrelor e tirofibana. Um total de 162 pacientes femininas idosas com diabetes e IAMCSST foram divididas aleatoriamente em dois grupos de acordo com o escore CRUSADE. O grupo B (69 pacientes com escore CRUSADE > 31) recebeu aspirina e ticagrelor. O grupo C (93 pacientes com escore CRUSADE < 30) recebeu aspirina, ticagrelor e tirofibana. Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados Após a PCI, o fluxo sanguíneo grau 3 Thrombolysis in Myocardial Infarction (TIMI) e a perfusão miocárdica TIMI grau 3 foram significativamente menos prevalentes no grupo B, em comparação com o grupo A (p < 0,05). Quando comparada aos grupos A e C, a incidência de complicações adversas maiores foi significativamente maior no grupo B (p < 0,05). Conclusão A TAP pode efetivamente reduzir a incidência de complicações maiores em pacientes idosas com diabetes e IAMCSST. No entanto, atenção cuidadosa deve ser dada à hemorragia em pacientes que recebem TAP. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

Abstract Background Dual antiplatelet therapy (DAPT) is the cornerstone treatment of acute myocardial infarction (AMI). Objective The present study aimed to investigate the efficacy and safety of triple antiplatelet therapy (TAPT) in elderly female patients with diabetes and ST segment elevation myocardial infarction (STEMI), who had undergone percutaneous coronary intervention (PCI). Methods We designed a randomized, single-blind study. Control group A (97 elderly male patients with diabetes and STEMI, whose CRUSADE scores were < 30) received aspirin, ticagrelor, and tirofiban. A total of 162 elderly female patients with diabetes and STEMI were randomly divided into two groups according to CRUSADE score. Group B (69 patients with CRUSADE score > 31) received aspirin and ticagrelor. Group C (93 patients with CRUSADE score < 30) received aspirin, ticagrelor and tirofiban. P values < 0.05 were considered statistically significant. Results Compared to the findings in group A, post-PCI Thrombolysis in Myocardial Infarction (TIMI) grade 3 blood flow and TIMI myocardial perfusion grade 3 were significantly less prevalent in group B (p < 0.05). When compared to groups A and C, the incidence of major adverse complications was significantly higher in group B (p < 0.05). Conclusion TAPT could effectively reduce the incidence of major complications in elderly female patients with diabetes and STEMI. However, close attention should be paid to hemorrhage in patients receiving TAPT. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

Abstract Background: Snakebites remain a major life-threatening event worldwide. It is still difficult to make a positive identification of snake species by clinicians in both Western medicine and Chinese medicine. The main reason for this is a shortage of diagnostic biomarkers and lack of knowledge about pathways of venom-induced toxicity. In traditional Chinese medicine, snakebites are considered to be treated with wind, fire, and wind-fire toxin, but additional studies are required. Methods: Cases of snakebite seen at the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine were grouped as follows: fire toxin - including four cases of bites by Agkistrodon acutus and three bites by Trimeresurus stejnegeri - and wind-fire toxin - four cases of bites by vipers and three bites by cobras. Serum protein quantification was performed using LC-MS/MS. Differential abundance proteins (DAPs) were identified from comparison of snakebites of each snake species and healthy controls. The protein interaction network was constructed using STITCH database. Results: Principal component analysis and hierarchical clustering of 474 unique proteins exhibited protein expression profiles of wind-fire toxins that are distinct from that of fire toxins. Ninety-three DAPs were identified in each snakebite subgroup as compared with healthy control, of which 38 proteins were found to have significantly different expression levels and 55 proteins displayed no expression in one subgroup, by subgroup comparison. GO analysis revealed that the DAPs participated in bicarbonate/oxygen transport and hydrogen peroxide catabolic process, and affected carbon-oxygen lyase activity and heme binding. Thirty DAPs directly or indirectly acted on hydrogen peroxide in the interaction network of proteins and drug compounds. The network was clustered into four groups: lipid metabolism and transport; IGF-mediated growth; oxygen transport; and innate immunity. Conclusions: Our results show that the pathways of snake venom-induced toxicity may form a protein network of antioxidant defense by regulating oxidative stress through interaction with hydrogen peroxide.

Two new coordination polymers [Zn (bdc)(bpybzimH2)](DMF)0.5 (1, H2bdc=1,4-dicarboxybenzene, bpybzimH2=6,6′-bis-(1H-benzoimidazol-2-yl)-2,2′-bipyridine, DMF=N,N-dimethylformamide) and [Co (bpybzimH2)(sbc)]H2O (2, H2sbc=4-mercaptobenzoic acid) have been successfully prepared under solvothermal conditions using the multi-N chelating organic ligand bpybzimH2 as the foundational building block. In addition, the Cell Counting Kit-8 assay was conducted to evaluate the anti-proliferation activity of compounds 1 and 2 against human spinal tumor cells OPM-2. The cell viability curves showed that the two compounds have anti-proliferation activity on spinal tumor cells, and the activity of compound 1 is higher than compound 2. The annexin V-FITC/PI assay and western blot were used to detect the apoptotic percentage of OPM-2 cells incubated with compounds 1 and 2. The YAP protein expression and its role in cell apoptosis were further studied with qRT-PCR, immunoblotting, and flow cytometer.

Conclusão A presente metanálise sugere que o polimorfismo C47T de SOD2 demonstra associação significativa com maior risco de PAIR na população chinesa. Há necessidade de novos estudos de grande porte bem concebidos, para confirmação dessa associação.

Abstract Introduction Currently, there is limited information about the relationship between manganese superoxide dismutase (sod2) c47t polymorphism and susceptibility to noise-induced hearing loss (NIHL). Objective The aim of this meta-analysis was to clarify the association between SOD2 C47T polymorphism and NIHL. Methods A search in PubMed and Web of Science was performed to collect data. All full-text, English-written studies containing sufficient and complete case-and-control data about the relationship between SOD2 C47T polymorphism and NIHL were included. Three eligible studies, comprising 1094 subjects, were identified. pooled odds ratios (ORs) and 95% confidence intervals (CI) were calculated to evaluate the strength of the association between SOD2 C47T polymorphism and NIHL. Results No significant association between C47T polymorphism and risk of NIHL was found with the following combinations: T vs. C (OR = 0.83; 95% CI = 0.63–1.09); TT vs. CC (OR = 0.49; 95% CI = 0.22–1.09); CT vs. CC (OR = 0.54; 95% CI = 0.25–1.17); TT vs. CC + CT (OR = 0.82; 95% CI = 0.50–1.32); CC vs. TT + TC (OR = 0.49; 95% CI = 0.23–1.04). However, in subgroup analysis, a significant association was found for TT vs. CC + CT (OR = 0.77; 95% CI = 0.42–1.41) in the Chinese population. Conclusion The present meta-analysis suggests that SOD2 C47T polymorphism is significantly associated with increased risk of NIHL in the Chinese population. Further large and well-designed studies are needed to confirm this association.
