ABSTRACT

Objective:To explore the predictive value of thrombomodulin (TM) for venous thromboembolism (VTE) in patients with lung cancer.Methods:The clinical data of 356 patients with lung cancer from March 2020 to March 2021 in Honghu People′s Hospital were retrospectively analyzed. Among them, 71 cases were diagnosed as VTE (VTE group) and 285 cases without VTE (non-VTE group). The D-Dimer (DD), fibrinogen degradation product (FDP), prothrombin time (PT), activated partial prothrombin time (APTT), thrombin time (TT) and TM were detected. Multivariate Logistic regression analysis was used to analyze the independent risk factors of VTE in patients with lung cancer, and the receiver operating characteristic (ROC) curve was used to analyze the predictive value of TM for VTE in patients with lung cancer.Results:There were no statistical differences in FDP, PT, APTT and TT between 2 groups ( P>0.05); the TM and DD in VTE group were significantly higher than those in non-VTE group: (11.61 ± 3.22) U/L vs. (7.70 ± 2.59) U/L and (5.42 ± 2.15) mg/L vs. (2.57 ± 0.96) mg/L, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis results showed that TM and DD were independent risk factors for VTE in patients with lung cancer ( OR = 0.27 and 0.66, 95% CI 0.19 to 0.39 and 0.56 to 0.78, P<0.01). ROC curve analysis result showed that the areas under curve of TM and DD for prediction VTE in patients with lung cancer were 0.830 and 0.892 (95% CI 0.772 to 0.889 and 0.842 to 0.941), and there was no statistical difference ( Z = 1.617, P>0.05); the optimum cut off values of TM and DD were 9.39 U/L and 3.83 mg/L, the sensitivity was 77.46% and 76.06%, and the specificity was 73.33% and 91.58%. Conclusions:The TM can be used as prediction index for VTE in patients with lung cancer.

ABSTRACT

Objective:To clarify the pathogenicity and further explore the association between genotype and clinical phenotype of this variant, analyzing a novel variation of SPAST gene in hereditary spastic paraplegia (HSP) family from Changzhi city, Shanxi Province.Methods:A family with HSP was tracked and collected in Neurology Department of Heping Hospital Affiliated to Changzhi Medical College in October 2019. Peripheral venous blood of 2 ml was extracted from the proband and 8 other members of the family, genomic DNA was extracted from the blood samples, and the genes of spastic paraplegia were screened by next-generation sequencing (NGS). HGMD, 1000G, OMIM databases and PolyPhen2, SIFT and other software were used for bioinformatics analysis of suspected mutations. Multiplex ligation-dependent probe amplification (MLPA) was used to further screen for total deletions/duplications in patients who remained negative after targeting NGS, and Sanger sequencing was performed to verify the suspected pathogenic mutation sites in the family to determine co-isolation of the mutation sites in the family members. Finally, it is necessary to refer to the latest version of The American College of Medical Genetics and Genomics (ACMG) sequence variation interpretation guidelines to interpret the mutation sites to determine pathogenicity.Results:The HSP family consist 47 members of 4 generations and 10 patients, with onset ages ranging from 2 to 44 years. The proband′s daughter only showed positive bilateral Babbitt signs on physical examination, and the rest of the patients showed spasticity and weakness of lower limbs with varying severity on this basis. Preliminary screening by next-generation sequencing technology showed that the proband had frame-shift variation of SPAST gene c.1057_1058insCC (p.Leu354HisfsTer11) and missense variation of DCTN1 gene c.2213A>G (p.Gln738Arg). Then, Sanger sequencing was used for in-family verification, which showed SPAST gene c.1057_1058insCC (p.Leu354HisfsTer11) was detected in the affected members include father, brother, son and daughter, and not detected in the unaffected normal members, the proband′s wife, mother, sister and sister-in-law. However, the unaffected of mother detected missense variation of DCTN1 gene c.2213A>G (p.Gln738Arg), while the remaining members did not detect this variation. The results of MLPA showed that no large fragment variation was found.Conclusions:The genetic pattern of the HSP family was autosomal dominant, and the clinical characteristics were consistent with hereditary spastic paraplegia type 4 (SPG4). Co-segregation of SPAST gene c.1057_1058insCC (p.Leu354HisfsTer11) was found in the HSP family and was the pathogenicity cause of this SPG4 family, and it was a newly discovered mutation locus.

ABSTRACT

Patients with mild stroke and transient ischemic attack (TIA) have a high risk of early recurrence or deterioration. Antiplatelet therapy has been recognized to reduce the risk of ischemic vascular events. All guidelines recommend antiplatelet therapy for patients with ischemic stroke. Dual antiplatelet therapy (DAPT) refers to the application of two drugs with different mechanisms to block platelet aggregation and prevent thrombosis. There are many combinations of DAPT, and its safety and effectiveness are still uncertain. This article reviews the efficacy and safety of DAPT in patients with mild stroke and TIA.

ABSTRACT

Objective:To investigate the predictive value of plasma myeloperoxidase (MPO) level for malignant arrhythmia (MA) in elderly patients with valvular heart disease.Methods:The clinical data of 92 elderly patients with valvular heart disease (valvular heart disease group) who underwent valve replacement surgery in Honghu People ′s Hospital in Hubei Province from May 2019 to May 2020 were retrospectively analyzed. The plasma MPO and serum N-terminal brain natriuretic peptide (NT-proBNP), lipoprotein a were detected and compared with those of 60 healthy examination people (healthy control group) during the same period. The independent risk factors of MA in elderly patients with valvular heart disease were analyzed by multivariate Logistic regression analysis method. Predictive value of MPO, NT-proBNP and lipoprotein a for MA in elderly patients with valvular heart disease were analyzed by receiver operating characteristic (ROC) curve. Results:The MPO, NT-proBNP and lipoprotein a in valvular heart disease group were significantly higher than those in healthy control group: (128.36 ± 39.25) mg/L vs. (89.16 ± 26.09) mg/L, (698.97 ± 154.65) ng/L vs. (47.95 ± 9.05) ng/L and (315.82 ± 79.96) mg/L vs. (153.37 ± 42.38) mg/L, and there were statistical differences ( P<0.01). The 92 elderly patients with valvular heart disease were followed up for 1 year. MA occurred in 36 cases (MA subgroup), and MA did not occur in 56 cases (non-MA subgroup). The MPO, NT-proBNP and lipoprotein a in MA subgroup were significantly higher than those in non-MA subgroup: (163.37 ± 29.11) mg/L vs. (105.86 ± 26.32) mg/L, (797.79 ± 113.54) ng/L vs. (635.45 ± 144.45) ng/L and (369.86 ± 45.27) mg/L vs. (281.08 ± 78.32) mg/L, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that the MPO, NT-proBNP and lipoprotein a were independent risk factors for MA in elderly patients with valvular heart disease ( OR = 0.937, 0.994 and 0.982; 95% CI 0.904 to 0.972, 0.988 to 0.999 and 0.968 to 0.996; P<0.01 or <0.05). ROC curve analysis result showed that the area under the curve of MPO for predicting MA in elderly patients with valvular heart disease was significantly greater than that of NT-proBNP and lipoprotein a (0.934 vs. 0.813 and 0.830, Z = 2.441 and 2.299, P<0.05). Conclusions:Plasma MPO is abnormally elevated in elderly patients with valvular heart disease, which has a good predictive value for the occurrence of postoperative MA in elderly patients with valvular heart disease.

ABSTRACT

Dihydroflavanol-4-reductase (Dfr) is a key enzyme that regulates the synthesis of anthocyanin and proanthocyanidin in the flavonoid biosynthesis pathway. To investigate the difference of dfr gene in Scutellaria baicalensis Georgi with different colors in the same ecological environment, three complete full-length sequences of dfr gene were cloned from the cDNA of S. baicalensis with white, purple-red and purple colors using homologous cloning and RACE techniques. The three genes were named Sbdfr1, Sbdfr2 and Sbdfr3, respectively, and their corresponding structures were analyzed. The results showed that all three Dfr proteins have highly conserved NADPH binding sites and substrate-specific binding sites. Phylogenetic analysis showed that they are closely related to that of the known S. viscidula (ACV49882.1). Analysis of key structural domains and 3D models revealed differences in the catalytically active regions on the surface of all three Dfr proteins, and their unique structural characteristics may provide favorable conditions for studying the substrate specificity of different Dfr proteins. qRT-PCR analysis shows that dfr was expressed at different level in all tissues except the roots of S. baicalensis in full-bloom. During floral development, the expression level of dfr in white and purple-flowered Scutellaria showed an overall upward trend. In purple-red-flowered Scutellaria, the expression first slowly increased, followed by a decrease, and then rapidly increased to the maximum. This research provides a theoretical basis for further exploring the mechanism and function of Dfr substrate selectivity, and are of great scientific value for elucidating the molecular mechanism of floral color variation in S. baicalensis.

ABSTRACT

Serum Cardiac troponin Ⅰ (cTn Ⅰ) and lactic acid were measured in 128 neonatal patients with hypoxic-ischemic encephalopathy and 38 healthy neonates (control group). Serum cTn Ⅰ and lactic acid levels were higher in neonates with hypoxic-ischemic encephalopathy than those in healthy neonates (P < 0. 05 ); and the differences of these values were also statistically significant between the serious patients and the mild patients (P<0.05). Serum cTn Ⅰ and lactic acid are two sensitive markers for degree of myocardial injury and hypoxia in neonatal patients with hypoxic-ischemic encephalopathy.
