RESUMEN

Coronavirus disease 2019 (COVID-19) has continued to spread globally since late 2019, representing a formidable challenge to the world's healthcare systems, wreaking havoc, and spreading rapidly through human contact. With fever, fatigue, and a persistent dry cough being the hallmark symptoms, this disease threatened to destabilize the delicate balance of our global community. Rapid and accurate diagnosis of COVID-19 is a prerequisite for understanding the number of confirmed cases in the world or a region, and an important factor in epidemic assessment and the development of control measures. It also plays a crucial role in ensuring that patients receive the appropriate medical treatment, leading to optimal patient care. Reverse transcription-polymerase chain reaction (RT-PCR) technology is currently the most mature method for detecting viral nucleic acids, but it has many drawbacks. Meanwhile, a variety of COVID-19 detection methods, including molecular biological diagnostic, immunodiagnostic, imaging, and artificial intelligence methods have been developed and applied in clinical practice to meet diverse scenarios and needs. These methods can help clinicians diagnose and treat COVID-19 patients. This review describes the variety of such methods used in China, providing an important reference in the field of the clinical diagnosis of COVID-19.

RESUMEN

Objective:To investigate the epidermal growth factor receptor (EGFR) gene mutation status in patients with non-small cell lung cancer (NSCLC) in Shiyan, Hubei and its relationship with the clinicopathological characteristics of patients.Methods:The data of 173 NSCLC patients who were admitted to Affiliated Dongfeng Hospital of Hubei University of Medicine from November 2017 to January 2020 were retrospectively analyzed. EGFR gene mutations in NSCLC tissues were detected by amplification refractory mutation system (ARMS)-TaqMan probe method, and clinicopathological data of patients were also collected to analyze the relationship between EGFR gene mutation status and clinicopathological characteristics of patients.Results:EGFR gene mutations were found in 76 of 173 patients, and the total mutation rate was 44.5%. The mutation rate of exon 18 was 6.6% (5/76), all of which were G719X mutation; the mutation rate of exon 19 was 46.1% (35/76), all of which were Del mutation; the mutation rate of exon 20 was 1.3% (1/76), which were EGFR gene 20ins mutation; the mutation rate of exon 21 was 44.7% (34/76), of which 33 cases were EGFR gene L858R mutation, and 1 case was EGFR gene L861Q mutation; 1 case was a double mutation of exon 19 Del combined with exon 20 T790M. The differences in EGFR mutation rates were statistically significant among patients with different gender, smoking history and pathological staging (all P < 0.05), and EGFR mutation rate in female patients was higher than that in male patients [59.7% (46/77) vs. 31.3% (30/96), χ2 = 14.08, P < 0.001], it was lower in patients with smoking history than that in patients without smoking history [27.1% (13/48) vs. 52.9% (63/119), χ2 = 9.22, P < 0.001], and it was higher in patients with adenocarcinoma than that in patients with non-adenocarcinoma [50.7% (75/148) vs. 4.0% (1/25), χ2 = 18.92, P < 0.001]. EGFR mutation status had no relevance with patients' age. Conclusions:The main types of EGFR mutations are exon 19 Del and exon 21 L858R in NSCLC patients in Shiyan, Hubei. EGFR mutations are more likely to occur in adenocarcinoma, female and no-smoking patients.

RESUMEN

Background The metabolites and metabolic pathways of hand-arm vibration syndrome have not yet been elucidated. Objective To investigate the effect of local vibration on endogenous metabolites in rat serum by metabolomic analysis, to preliminarily explore the potential metabolic pathway of endogenous metabolites, so as to provide evidence for further research on the mechanism of hand-arm vibration syndrome. Methods Thirty-two SPF male SD rats, (211.3±11.1) g, 7−8 weeks of age, were selected and randomly divided into three groups: control group (14 rats, without vibration), 7 d vibration group (9 rats, continuously vibration for 7 d), and 14 d vibration group (9 rats, continuous vibration for 14 d). The vibration rats were vibrated every day for 4 h, the frequency weighted acceleration was 4.9 m·s−2, the vibration frequency was 125 Hz, and the vibration direction was one-way vertical vibration. The control group had the same conditions except not contacting vibration. After the vibration exposure, the blood samples taken from the abnormal aorta of rats were collected, and the changes of rat serum metabolome were analyzed by ultra-performance liquid chromatography-tandem time-of-flight mass spectrometry. Principal components analysis (PCA) was used to explore changes in rat serum metabolic profile, and orthogonal partial least squares-discriminant analysis (OPLS-DA) was used to screen out differential metabolites. Combined with online databases, a metabolic pathway enrichment analysis of differential metabolites was performed. Results The PCA analysis showed that compared with the control group, the rat serum metabolic profiles in the 7 d group and the 14 d group were clearly differentiated, and the rat serum metabolic profiles in the 7 d group and the 14 d group partially overlapped. The OPLS-DA analysis showed significant differences between groups. The main parameters were: model interpretation rate R2Y=0.914, model predictive ability Q2=0.58. The OPLS-DA analysis screened out 26 and 119 differential metabolites from the 7 d group and the 14 d group respectively, and there were 24 common differential metabolites between the 7 d group and the 14 d group. The metabolomic pathway analysis showed that local vibration-induced changes in rat serum metabolism were mainly related to arachidonic acid metabolism in the 14 d group, among which the metabolites with significant effects were arachidonic acid, prostaglandin E2, and prostaglandin D2. Conclusion Local vibration could affect the normal metabolism in rats, and the metabolic pathway with significant influence is arachidonic acid metabolism after a 14 d exposure and the involved metabolites are arachidonic acid, prostaglandin E2, and prostaglandin D2.

RESUMEN

Background Long-term exposure to hand-transmitted vibration can lead to hand-arm vibration syndrome, one manifestation of which is impaired peripheral blood circulation in the arms. Altered expressions of prostacyclin I2 (PGI2) and thromboxane A2 (TXA2) in blood may be one of the important mechanisms of vibration-induced hand-arm vibration syndrome. Objective To reveal the effects of rat tail vibration on the expressions of PGI2 and TXA2 in plasma, and to establish the correlation between the change of rat plasma PGI2 to TXA2 ratio and rat tail vibration. Methods Fifty SPF-grade male SD rats were randomly divided into five groups: control group, 1 d exposure group, 3 d exposure group, 7 d exposure group, and 14 d exposure group, with 10 rats in each group. The rats were placed in rat immobilizes on a immobilization table, and the rats' tails were connected to a shaker and fixed with medical tape. There was no overlap between the immobilizes and between the rats' tails by no contact between the immobilization table and the shaker. The exposure dose was 125 Hz, 5.9 m·s−2, 4 h·d−1, and the vibration direction was linear vertical vibration. Abdominal aortic blood was taken at the end of vibration exposure, and the expressions of PGI2, TXA2, and their hydrolysates 6-keto-prostaglandin F1α (6-keto-PGF1α) and thromboxane B2 (TXB2) were measured by enzyme-linked immunosorbent assay, and the 6-keto-PGF1α/TXB2 values were calculated. Spearman rank correlation was used to analyze whether the expression of vascular factors correlated with the accumulated time of vibration. Results The expression levels of plasma 6-keto-PGF1α were (896.12±124.37), (1068.13±119.41), (1215.26±122.64), and (1317.94±106.54) ng·L−1 in the 1 d, 3 d, 7 d, and 14 d groups of rats, respectively, which were higher than that in the control group, (830.60±109.47) ng·L−1 (P<0.001). The PGI2 expression levels were (86.49±2.40), (107.90±2.65), (114.02±2.16), and (126.95±1.94) ng·L−1 in the 1 d, 3 d, 7 d, and 14 d groups of rats, respectively, all higher than (60.09±2.11) ng·L−1 in the control group (P<0.001). The expression levels of TXB2 were (132.14±4.10), (145.52±4.09), (179.91±4.98), and (204.10±3.22) ng·L−1 in the 1 d, 3 d, 7 d, and 14 d groups of rats, respectively, which were higher than that in the control group, (106.08±3.26) ng·L−1 (P<0.001). The expression levels of plasma TXA2 were (211.99±3.24), (236.33±3.88), and (245.45±4.23) ng·L−1 in rats in the 3 d, 7 d, and 14 d groups, respectively, which were all elevated compared with (174.79±4.19) ng·L−1 in the control group (P<0.001). Compared with the control group, the 6-keto-PGF1α/TXB2 values were decreased in the 7 d and 14 d groups (P<0.05). The 6-keto-PGF1α, PGI2, TXB2, and TXA2 expressions were positively correlated with vibration accumulation time (r=0.84, 0.84, 0.80, 0.84, P<0.001) and the 6-keto-PGF1α/TXB2 values were negatively correlated with vibration accumulation time (r=-0.24, P=0.003). Conclusion Local exposure of rat tail to vibration could increase the expressions of PGI2 and TXA2 in blood, and the elevated expressions show a dose-effect relationship with the duration of vibration exposure, but the PGI2/TXA2 tends to decrease with the accumulation of vibration exposure.

RESUMEN

Background Hand-arm vibration disease is harmful to human body, but there are no effective diagnosis and treatment so far, and current occupational exposure limits underestimate the health damage caused by high-frequency vibration exposure. Objective To evaluate and compare the damage to workers' peripheral circulation and peripheral nerve caused by different frequencies of vibration operation. Methods Drilling workers (n=187) from a mining company in Shandong Province and golf club head grinding workers (n=228) from a sports equipment factory in Guangdong Province were selected as study subjects. Hand symptoms were investigated. SV106 vibration meter was used to measure the target operation-associated vibration frequency spectrum. The 8 h energy-equivalent frequency weighted acceleration, cumulative vibration exposure level (CVEL), and the working age related to causing white finger in 10% of an exposed group were calculated. Result The study subjects were all male. More grinding workers reported hand symptoms than the drilling workers, e.g. peripheral circulation injury (52.6% vs 19.3%), peripheral nerve injury (71.5% vs 23.0%), hand stiffness (64.0% vs 7.0%), and deformed fingers (69.7% vs 4.3%) (all P<0.001). The main vibration frequencies of grinding operation (500-800 Hz) were much higher than those of drilling operation (125~160 Hz). CVEL and working age of vibration exposure showed a linear rising relationship with the cumulative prevalence rate of peripheral circulation and peripheral never injury, the fitting lines all showed good fitting effects (R2=0.812-0.988), and the slope of the fitting line of the grinding workers was larger than that of the drilling workers. The working age of vibration exposure associated with 10% cumulative prevalence of white finger was shorter in the grinding workers than in the drilling workers (6.81 years vs 10.27 years). According to the ISO prediction formula, the working age of vibration exposure was associated with 10% white finger prevalence shorter in the drilling workers than in the grinding workers (3.12 years vs 8.23 years). Conclusion Both the vibration exposure level and the prevalence of hand symptoms are high in two groups of workers with different vibration frequencies, and vibration exposure at a higher frequency tends to have severer damage to workers' hands.

RESUMEN

This study aims to explore the diagnostic value of specific immunoglobulin E (sIgE) and specific immunoglobulin G (sIgG) of Aspergillus fumigatus in the diagnosis of allergic broncho-pulmonary aspergillosis (ABPA) and severe asthma with fungal sensitization (SAFS). A total of 17 ABPA patients and 14 SAFS patients were enrolled. The levels of sIgG [2 294.00 (1 527.00, 14 170.00) U/ml vs. 972.60 (650.90, 1 792.00) U/ml] and sIgE [8.77 (1.64, 16.85) kU/L vs. 1.04 (0.70, 2.05) kU/L] in ABPA patients were significantly higher than those in SAFS patients (P<0.05). Aspergillus fumigatus sIgG was strongly correlated with Aspergillus fumigatus sIgE (rs=0.797, P<0.001) in ABPA patients. When combined with Aspergillus fumigatus sIgG (>1 000.00 U/mL) and Aspergillus fumigatus sIgE (>1.00 kU/L), the sensitivity was 82.3% and specificity 78.6% for the differential diagnosis of ABPA and SAFS. It demonstrates the diagnostic value of Aspergillus fumigatus sIgG and sIgE.

RESUMEN

Objective To assess the performance of pediatric clinical illness score (PCIS), pediatric risk of mortality scoreⅢ(PRISMⅢ), pediatric logistic organ dysfunction score 2 (PELOD-2), and pediatric multiple organ dysfunction score (P-MODS) in predicting mortality in critically ill pediatric patients. Methods The data of critically ill pediatric patients admitted to Pediatric Intensive Care Unit (PICU) of First Affiliated Hospital of Sun Yat-Sen University from August 2012 to May 2017 were retrospectively analyzed. The gender, age, basic diseases, the length of PICU stay were collected. The children were divided into survival group and non-survival group according to the clinical outcome during hospitalization. The variables of PCIS, PRISMⅢ, PELOD-2, and P-MODS were collected and scored. Receiver operating characteristic (ROC) curve was plotted, the efficiency of PCIS, PRISMⅢ, PELOD-2, and P-MODS for predicting death were evaluated by the area under ROC curve (AUC). Hosmer-Lemeshow goodness of fit test was used to evaluate the fitting degree of each scoring system to predict the mortality and the actual mortality. Results Of 461 critically ill children, 35 children were excluded because of serious data loss, hospital stay not exceeding 24 hours, and death within 8 hours after admission. Finally, a total of 426 pediatric patients were enrolled in this study. 355 pediatric patients were survived, while 71 were not survived during hospitalization, with the mortality of 16.7%. There was no significant difference in gender, age, underlying diseases or length of PICU stay between the two groups. PCIS score in non-survival group was significantly lower than that of survival group [80 (76, 88) vs. 86 (80, 92)], and PRISMⅢ, PELOD-2 and P-MODS scores were significantly increased [PRISMⅢ: 16 (13, 22) vs. 12 (10, 15), PELOD-2: 6 (5, 9) vs. 4 (2, 5), P-MODS: 6 (4, 9) vs. 3 (2, 6), all P < 0.01]. ROC curve analysis showed that the AUCs of PCIS, PRISMⅢ, PELOD-2, and P-MODS for predicting death of critical ill children were 0.649, 0.731, 0.773, and 0.747, respectively. Hosmer-Lemeshow test showed that PCIS predicted the mortality and the actual mortality in the best fitting effect (χ2= 7.573, P = 0.476), followed by PELOD-2 and P-MODS (χ12 = 9.551, P1= 0.145; χ22 = 10.343, P2= 0.111), while PRISMⅢ had poor fitting effect (χ2= 43.549, P < 0.001). Conclusions PRISMⅢ, PELOD-2 and P-MODS can discriminate between survivors and moribund patients well, and assessing the condition of critically ill pediatric patients with relatively accuracy. PCIS was the best fitting effect in predicting mortality and actual mortality, followed by PELOD-2 and P-MODS, while PRISMⅢ had poor fitting effect.

RESUMEN

Objective Type A lamins are encoded by LMNA and a major component of the nuclear lamina, which have been suggested to play important roles in chromatin organization, transcription, DNA replication, and cell apoptosis. The aim of this study was to analyze the bioinformation of zebrafish lamins. Methods A phylogeny analysis was figured out with protein sequences of different species by Clustal X and MEGA 4?0 software. Then we compared the lamin protein sequences of different species with that of zebrafish by BLAST tool from NCBI. A figure of synteny analysis results was done with lamin sequence information of humans, murine and zebrafish cited from UCSC, Vega and Ensemble. Results The a?nalysis results showed that lmna, lmnb1, and lmnb2 genes of zebrafish are highly conservative and they may be homology of human LMNA, LMNB1 and LMNB2 genes. Conclusions Zebrafish lamins and human lamins have homologous sequence similarity, indicating that these two genes are orthologous genes.

RESUMEN

AIM:To investigate whether the opening of ATP-sensitive K+(KATP) channels protects H9c2 car-diac cells against high glucose ( HG)-induced injury and inflammation by inhibiting the Toll-like receptor 4 ( TLR4 )/nu-clear factor-κB ( NF-κB) pathway.METHODS:The protein levels of TLR4 and NF-κB p65 were determined by Western blot.The levels of interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) were detected by ELISA.The cell viabil-ity was measured by CCK-8 assay.Mitochondrial membrane potential (MMP) was examined by rhodamine 123 (Rh 123) staining followed by photofluorography.The intracellular levels of reactive oxygen species ( ROS) were detected by 2′, 7′- dichlorfluorescein-diacetate (DCFH-DA) staining followed by photofluorography.The number of apoptotic cells was ob-served by Hoechst 33258 nuclear staining followed by photofluorography.RESULTS: After the H9c2 cardiac cells were treated with HG (35 mmol/L glucose) for 24 h, the protein levels of TLR4 and phosphorylated NF-κB p65 ( p-NF-κB p65) were significantly increased.Pretreatment of the cells with 100 μmol/L diazoxide ( DZ, a KATP channel opener) for 30 min before exposure to HG considerably blocked the up-regulation of the TLR4 and p-NF-κB protein levels induced by HG.Moreover, co-treatment of the cells with 30 μmol/L TAK-242 (an inhibitor of TLR4) obviously inhibited the HG-in-duced up-regulation of the p-NF-κB p65 protein level.On the other hand, pretreatment of the cells with 100 μmol/L DZ had a clear myocardial protection effect, which attenuated the HG-induced cytotoxicity, inflammatory response, mitochon-drial damage, oxidative stress and apoptosis, evidenced by an increase in the cell viability, and decreases in the levels of IL-1βand TNF-α, MMP loss, ROS generation and the number of apoptotic cells.Similarly, co-treatment of H9c2 cardiac cells with 30μmol/L TAK-242 or 100μmol/L PDTC ( an inhibitor of NF-κB) and HG for 24 h also obviously reduced the above injuries and inflammation induced by HG.CONCLUSION: The opening of KATP channels protects H9c2 cardiac cells against HG-induced injury and inflammation by inhibiting the TLR4/NF-κB pathway.

RESUMEN

[ ABSTRACT] AIM:To investigate the role of ATP-sensitive potassium ( KATP ) channels in the inhibitory effect of hydrogen sulfide ( H2 S) on high glucose ( HG)-induced inflammation mediated by necroptosis in H 9c2 cardiac cells. METHODS:The expression levels of receptor-interacting protein 3 ( RIP3; an indicator of necroptosis ) and cyclooxyge-nase-2 (COX-2) were determined by Western blot.The levels of interleukin-1β(IL-1β) and tumor necrosis factor-α( TNF-α) were detected by ELISA .RESULTS:After H9c2 cardiac cells were treated with 35 mmol/L glucose ( HG) for 24 h, the expression of RIP3 was significantly increased .Pre-treatment of the cells with 100 μmol/L diazoxide ( DZ; a KATP channel opener) or 400 μmol/L NaHS (a donor of H2S) for 30 min considerably blocked the up-regulation of RIP3 induced by HG.Moreover, pre-treatment of the cells with 100 μmol/L 5-hydroxydecanoic acid (5-HD; a KATP channel blocker) attenuated the inhibitory effect of NaHS on HG-induced up-regulation of RIP3.On the other hand, co-treatment of the cells with 100μmol/L necrostatin-1 ( a specific inhibitor of necroptosis ) or pre-treatment of the cells with 100 μmol/L DZ or 400 μmol/L NaHS attenuated HG-induced inflammatory responses , evidenced by decreases in the expression of COX-2 and secretion levels of IL-1βand TNF-α.However , pre-treatment of the cells with 100 μmol/L 5-HD significantly attenuated the above anti-inflammatory effects of NaHS.CONCLUSION:KATP channels play an important role in the inhib-itory effect of H2 S on HG-induced inflammation mediated by necroptosis in H 9c2 cardiac cells.

RESUMEN

Objective To investigate the types and distributions of allergens, and the responsiveness to these allergens SIgE and tIgE as related to allergic disorders in patients with allergies in Guangdong. Methods Serum samples were obtained from patients with allergic disorders (n = 7 144) who visited our hospital between 2009 and 2014. The sera were subjected to analysis of 15 common allergens. Results The positive rates of sIgE and tIgE were 62.4%and 54.6%, respectively. Dermatophagoides pteronyssinus(Der p) had the highest prevalence of aeroallergen-specific IgE and milk the highest prevalence of food allergen-specific IgE. Other aeroallergens and food allergens produced mild responses except Der p and Der f. The sensitization peak of Der p and Der f appeared at the age of 10 to 12 years. The sensitization peak of milk appeared at the age of less than 3 years and that of eggs did at the aged of 4 to 6 years. The averaged tIgE positive rate went up with the increase in the number of allergen sensitization. Conclusion Der p, Der f, milk and eggs are major sensitizers responsible for common allergic disorders in Guangdong. Knowledge concerning allergen characteristics at various age groups may be helpful for early diagnosis and intervention for allergies.
