RESUMO
OBJECTIVE: The purpose of present study was to comprehensívely explore the efficacy and safety of prothrombín complex concentrate (PCC) to treat massíve bleedíng in patíents undergoing cardiac surgery. METHODS: PubMed®, Embase, and Cochrane Líbrary databases were searched for studíes ínvestigating PCC administratíon duríng cardiac surgery published before September 10, 2022. Mean dífference (MD) wíth 95% confidence interval (CI) was applíed to analyze continuous data, and dichotomous data were analyzed as risk ratio (RR) with 95% CI. RESULTS: Twelve studies were included in the meta-analysis. Compared with other non-PCC treatment regimens, PCC was not assocíated with elevated mortality (RR=1.18, 95% CI=0.86-1.60, P=0.30, I2=0%), shorter hospital stay (MD=-2.17 days; 95% CI=-5.62-1.28, P=0.22, I2=91%), reduced total thoracic drainage (MD=-67.94 ml, 95% CI=-239.52-103.65, P=0.44, I2=91%), thromboembolíc events (RR=1.10, 95% CI=0.74-1.65, P=0.63, I2=39%), increase ín atríal fibríllatíon events (RR=0.73, 95% CI=0.52-1.05, P=0.24, I2=29%), and myocardial infarction (RR=1.10, 95% CI=0.80-1.51, P=0.57, I2=81%). However, PCC use was associated with reduced intensive care unit length of stay (MD=-0.81 days, 95% CI=-1.48- -0.13, P=0.02, I2=0%), bleeding (MD=-248.67 ml, 95% CI=-465.36- -31.97, P=0.02, I2=84%), and intra-aortic balloon pump/extracorporeal membrane oxygenation (RR=0.65, 95% CI=0.42-0.996, P=0.05, I2=0%) when compared with non-PCC treatment regimens. CONCLUSION: The use of PCC in cardiac surgery did not correlate with mortality, length of hospítal stay, thoracic drainage, atríal fibríllatíon, myocardíal ínfarction, and thromboembolíc events. However, PCC sígnificantly improved postoperatíve intensíve care unít length of stay, bleedíng, and intra-aortic balloon pump/ extracorporeal membrane oxygenation outcomes ín patients undergoing cardíac surgery.

ABSTRACT Objective: The purpose of present study was to comprehensively explore the efficacy and safety of prothrombin complex concentrate (PCC) to treat massive bleeding in patients undergoing cardiac surgery. Methods: PubMed®, Embase, and Cochrane Library databases were searched for studies investigating PCC administration during cardiac surgery published before September 10, 2022. Mean difference (MD) with 95% confidence interval (CI) was applied to analyze continuous data, and dichotomous data were analyzed as risk ratio (RR) with 95% CI. Results: Twelve studies were included in the meta-analysis. Compared with other non-PCC treatment regimens, PCC was not associated with elevated mortality (RR=1.18, 95% CI=0.86-1.60, P=0.30, I2=0%), shorter hospital stay (MD=-2.17 days; 95% CI=-5.62-1.28, P=0.22, I2=91%), reduced total thoracic drainage (MD=-67.94 ml, 95% CI=-239.52-103.65, P=0.44, I2=91%), thromboembolic events (RR=1.10, 95% CI=0.74-1.65, P=0.63, I2=39%), increase in atrial fibrillation events (RR=0.73, 95% CI=0.52-1.05, P=0.24, I2=29%), and myocardial infarction (RR=1.10, 95% CI=0.80-1.51, P=0.57, I2=81%). However, PCC use was associated with reduced intensive care unit length of stay (MD=-0.81 days, 95% CI=-1.48- -0.13, P=0.02, I2=0%), bleeding (MD=-248.67 ml, 95% CI=-465.36- -31.97, P=0.02, I2=84%), and intra-aortic balloon pump/extracorporeal membrane oxygenation (RR=0.65, 95% CI=0.42-0.996, P=0.05, I2=0%) when compared with non-PCC treatment regimens. Conclusion: The use of PCC in cardiac surgery did not correlate with mortality, length of hospital stay, thoracic drainage, atrial fibrillation, myocardial infarction, and thromboembolic events. However, PCC significantly improved postoperative intensive care unit length of stay, bleeding, and intra-aortic balloon pump/ extracorporeal membrane oxygenation outcomes in patients undergoing cardiac surgery.
RESUMO
Abstract This study aimed to investigate the molecular mechanism of Picrasma quassioides Benn against inflammation by means of network pharmacology. The paper will provide a reference for multi-target and multi-channel treatment of inflammation with traditional Chinese medicine. Through screening and analysis, 11 active ingredients and 109 anti-inflammation prediction targets were obtained and constructed a compound-target network. The targets such as VEGFA, TLR4 and STAT3 may play a crucial role. Network enrichment analysis showed that the 109 potential targets constitute a number of pathways or inflammatory reactions closely related to inflammation, including NF-κB signaling pathway and MAPK signaling pathway. The docking results indicated that the binding energy of Picrasidine Y and the inflammatory factors VEGFA is the highest. This study predicted the role of multiple active compounds in the alkaloids of Picrasma in the inflammatory response, and provided a theoretical basis for the anti-inflammatory mechanism of Picrasma

ABSTRACT Background: The diagnostic value and suitability of prostate cancer antigen 3 (PCA3) for the detection of prostate cancer (PCa) have been inconsistent in previous studies. Thus, the aim of the present meta-analysis was performed to systematically evaluate the diagnostic value of PCA3 for PCa. Materials and Methods: A meta-analysis was performed to search relevant studies using online databases EMBASE, PubMed and Web of Science published until February 1st, 2019. Ultimately, 65 studies met the inclusion criteria for this meta-analysis with 8.139 cases and 14.116 controls. The sensitivity, specificity, positive likelihood ratios (LR+), negative likelihood ratios (LR−), and other measures of PCA3 were pooled and determined to evaluate the diagnostic rate of PCa by the random-effect model. Results: With PCA3, the pooled overall diagnostic sensitivity, specificity, LR+, LR−, and 95% confidence intervals (CIs) for predicting significant PCa were 0.68 (0.64-0.72), 0.72 (0.68-0.75), 2.41 (2.16-2.69), 0.44 (0.40-0.49), respectively. Besides, the summary diagnostic odds ratio (DOR) and 95% CIs for PCA3 was 5.44 (4.53-6.53). In addition, the area under summary receiver operating characteristic (sROC) curves and 95% CIs was 0.76 (0.72-0.79). The major design deficiencies of included studies were differential verification bias, and a lack of clear inclusion and exclusion criteria. Conclusions: The results of this meta-analysis suggested that PCA3 was a non-invasive method with the acceptable sensitivity and specificity in the diagnosis of PCa, to distinguish between patients and healthy individuals. To validate the potential applicability of PCA3 in the diagnosis of PCa, more rigorous studies were needed to confirm these conclusions.

This study examined the expression and potential mechanism of microRNA (miRNA)-424-5p in nasopharyngeal carcinoma (NPC). NPC tissues were collected from 40 patients who were enrolled in the study, and skin samples were collected from 26 healthy subjects during plastic surgery as controls. We performed various in vitro assays using miR-424-5p to examine its function in primary NPC-1 cells. Bioinformatics was employed to analyze potential target genes and signaling pathways of miR-424-5p. We found that miR-424-5p expression in NPC tissues is downregulated and negatively correlated with lymph node metastasis and clinical staging. Expression of miR-424-5p in NPC cells was also downregulated, and transfection with miR-424-5p mimics inhibited proliferation, migration, and invasion of NPC-1 cells. Bioinformatics identified the AKT3 gene as a potential target of miR-424-5p and dual luciferase assays confirmed this finding. Upregulation of AKT3 expression rescued the inhibitory effect of miR-424-5p on the proliferation, migration, and invasion. Our results suggest that miR-424-5p inhibited the proliferation, migration, and invasion of NPC cells by decreasing AKT3 expression.

The influence of nitrogen (N) limitation on the cell growth, chlorophyll content, intracellular lipid production and expression levels of two pathway genes in Chlorella sorokiniana was investigated in mixotrophic culture in this study. The maximum biomass concentration of C. sorokiniana cultured in modified BG11 medium containing 3, 6, 9, 12 and 15 mM N were 1.60, 2.21, 2.74, 3.18 and 3.21 g/L of dry cell weight, respectively with maximum specific growth rate of 0.180, 0.198, 0.201, 0.203, 0.206 day−1 during culture with an initial N feed of 3, 6, 9, 12 and 15 mM in the first eight days, respectively. The maximum lipid content was 51 % with 3 mM N. However, the maximum lipid productivity of 0.00884 g L−1 day−1 was achieved with 6 mM N. Expression levels of accD (heteromeric acetyl-CoA carboxylase beta subunit) and accI (homomeric acetyl-CoA carboxylase) genes in C. sorokiniana were studied by real-time PCR. Increased expression levels of accD reflected the increased lipid content in stationary phase. In contrast, expression of the acc1 gene always remained low, showing that the gene might not be critical for lipid accumulation.
RESUMO
The discovery of new drugs requires the development of improved animal models for drug testing. The Chinese tree shrew is considered to be a realistic candidate model. To assess the potential of the Chinese tree shrew for pharmacological testing, we performed drug target prediction and analysis on genomic and transcriptomic scales. Using our pipeline, 3,482 proteins were predicted to be drug targets. Of these predicted targets, 446 and 1,049 proteins with the highest rank and total scores, respectively, included homologs of targets for cancer chemotherapy, depression, age-related decline and cardiovascular disease. Based on comparative analyses, more than half of drug target proteins identified from the tree shrew genome were shown to be higher similarity to human targets than in the mouse. Target validation also demonstrated that the constitutive expression of the proteinase-activated receptors of tree shrew platelets is similar to that of human platelets but differs from that of mouse platelets. We developed an effective pipeline and search strategy for drug target prediction and the evaluation of model-based target identification for drug testing. This work provides useful information for future studies of the Chinese tree shrew as a source of novel targets for drug discovery research.
