Val629fs) on exon 15 in FERMT1. The patient's parents exhibited heterogeneous identical mutations. This mutation was absent in the control group. The results of the multi-gene panel test were further verified by Sanger sequencing. Based on the clinical manifestations and genetic analysis, KS was diagnosed in the patient. The current study reported a Chinese case of KS with one novel mutation c.1885_1901del in FERMT1 and presented a brief summary of all pathogenic mutations in FERMT1 that have been reported in KS between 1984 and May 2020 via a PubMed literature search.Allergic rhinitis (AR) is a common upper airway disease attributed to a variety of risk factors, such as environmental exposures and genetic susceptibility. The commonly observed comorbidity of asthma and AR in the clinic suggests the presence of shared genetic risk factors and biological mechanisms between these diseases. Interleukin (IL)-33 has been indicated to be an important factor driving asthma susceptibility and pathogenesis using both genome-wide association studies and functional studies in model animals. Although previous studies have reported the putative association of this gene with AR, evidence for the association of genetic variations of IL-33 with the disease is still missing. To examine whether variations in the IL-33 gene confer a genetic risk of AR, a total of 769 patients with AR and 769 age- and sex-matched healthy controls were recruited among Han Chinese residents in the Hubei province, and 14 single-nucleotide polymorphisms (SNPs) spanning the IL-33 gene were examined for their association with the risk of AR. The results indicated that five SNPs, which were in a moderate linkage disequilibrium and were located in the 5'-flanking region of IL-33, exhibited significant associations with the risk of AR, and these associations were additionally supported by genotypic and haplotypic analyses. Notably, three of the five IL-33 SNPs have been previously reported to exhibit genome-wide associations with asthma, and their alleles were also revealed to confer an increased risk of AR in the present study. In summary, the results of the current study suggested that certain variations in the IL-33 gene represent a potential risk for AR, and indicated a shared genetic basis between AR and asthma.Hyponatremia is a risk factor associated with poor prognosis in patients with heart failure (HF) with reduced ejection fraction. However, whether hyponatremia has a similar role in patients with HF with preserved ejection fraction (HFpEF) has remained controversial. Therefore, the present study aimed to investigate the clinical characteristics and 24-month prognostic profile of a cohort of patients with HFpEF in China. From a registered observational cohort study on 1,027 subjects with HF, 496 patients with HFpEF were included. The association between baseline hyponatremia on admission and 24-month adverse outcomes (including all-cause mortality, re-hospitalization for HF and stroke) was analyzed using logistic regression with the Cox proportional hazards model. Of the 496 patients with HFpEF with a mean age of 72.8 years and proportion of males of 53.0%, 71 patients were diagnosed with hyponatremia. Furthermore, 29 patients (5.8%) were lost to follow-up. The hyponatremia group had lower blood pressure and se 95% CI=1.04-2.89, P=0.016]. Collectively, the present results suggested that hyponatremia on admission was significantly associated with all-cause mortality, re-hospitalization and stroke within 24 months in a cohort of hospitalized patients with HFpEF in China. Thus, hyponatremia should be carefully monitored and frequently adjusted in patients with HFpEF (NCT04062500).Tuberculosis (TB) is one of the most common infectious diseases globally. N6-methyladenosine in vitro The surfactant protein C (SFTPC), which is involved in innate immunity and surfactant function in the lung, may contribute toward the progression of TB. The aim of the present study was to preliminarily investigate the possible association of single nucleotide polymorphisms (SNPs) in the SFTPC gene with TB susceptibility and clinical phenotypes in a Western Chinese Han population. The improved multiplex ligation detection reaction method was used to genotype 6 SNPs in SFTPC, in 900 patients with TB and 1,534 healthy control subjects. It was found that the A allele for rs1124 and the C allele for rs8192313 were associated with increased susceptibility to TB, P=0.024 and P=0.045, respectively. However, these two P-values were not significant following Bonferroni correction. In all samples, the haplotype [CGA], representing three SFTPC variants, was revealed to increase the risk of TB (P=0.001 and P=0.005, following Bonferroni correction). Furthermore, patients with the AA genotype for rs1124 and with the CC genotype for rs8192313 were associated with higher levels of C-reactive protein (P=0.001 and P=0.005, respectively). The results of the present study indicated that the SFTPC SNPs may increase the susceptibility to TB and the immune response of the host to Mycobacterium tuberculosis and may potentially be novel biomarkers for the pathogenesis of TB.The present study examined whether Panax notoginseng saponins (PNS) alleviated advanced glycation end product (AGE)-induced apoptosis in human umbilical vein endothelial cells (HUVECs). HUVECs were incubated with 300 µg/ml AGEs alone or AGEs and PNS (0.05, 0.5 or 1 mg/ml) for 48 h. The results of the present study demonstrated that PNS effectively promoted cell viability, inhibited apoptosis and suppressed the activity of caspase-3 in AGE-induced HUVECs. The activities of monocyte chemoattractant protein-1 and malondialdehyde were reduced, and superoxide dismutase activity was increased following treatment with PNS. Furthermore, PNS significantly increased the expression of silent information regulator 1 (SIRT1) and transforming growth factor (TGF)-β1 proteins, and suppressed the expression of inducible nitric oxide synthase and cyclooxyggenase-2 proteins in AGE-induced HUVECs. Therefore, the present study demonstrated that PNS reduced AGE-induced apoptosis by upregulating SIRT1 and antioxidants in HUVECs. The present findings suggest that the PNS may as an important pharmacological agent for AGE-induced cardiovascular injury.
