Objective The study aimed to investigate 15 autosomal loci polymorphism(such as D3S1358 and TPOX)in Nujiang Bai nationality,in order to construct genetic basic data of Bai population and provide a foundation for population study and forensic cases. Methods Venous blood was collected from 124 unrelated Bai individuals in Nujiang,Yunnan province. DNA was extracted by classical organic solvent extraction. PCR technique was applied to amplify the sequence of autosomal loci. The products were measured by electrical fluoroscopy. The gene frequencies of 15 STR loci were investigated and genetic polymorphisms were analyzed. ResultsGene polymorphisms of 15 STR loci were detected and the distributions of genotype conformed with Hardy-Weinberg balance law(P > 0.05). The cumulative match probability(CPM)was 4.869×10-17,the cumulative excluding probability(CPE)was 99.999 99%,and the combined power of discrimination(CDP)was 99.999 97%. ConclusionThe 15 STR loci used in this study were highly polymorphic informative content in Bai population and could be applied to population study and forensic practice.

Objective To compare the efficacy and safety of linezolid and vancomycin in the treatment of hospitalized patients with Enterococcus bloodstream infection,to provide medication choices for clinical practice.Methods The clinical data of 99 inpatients with Enterococcus bloodstream infection in Yantai Yuhuangding Hospital from June 2019 to June 2023 were retrospectively collected,and the patients were divided into linezolid group and vancomycin group according to the drug used.confounding factors were controlled by propensity score matching method.The clinical efficacy,inflammatory factor levels,and adverse reactions of the two groups were compared.Results After using propensity score matching,25 patients were assigned to both linezolid group and vancomycin group.There was no significant difference in the effective rate,30-day mortality,incidence of adverse reactions and inflammatory factor levels between the two groups(P>0.05).Conclusion In the treatment of patients with Enterococcus bloodstream infection,the efficacy and safety of linezolid and vancomycin are the same.Linezolid can be a prioritized medicine when vancomycin causes nephrotoxicity and concentration does not meet the standard or exceeds the standard.Due to limitation of sample size and information collection,more high-quality studies are required to verify above conclusions.

Objective:To establish and apply the electronic further modified early warning score system (e-fMEWS), and explore its role in the condition evaluation and early warning of inpatients in non-critical units, so as to provide clinical nurses with an early and dynamic method to identify the potential deterioration risk of patients' condition.Methods:A retrospective analysis of 262 805 inpatients in multiple non-critical units of the Second Affiliated Hospital of Zhejiang University School of Medicine from January to December 2018 and January to December 2020 was performed. The patients who were hospitalized from January to December 2018 were used as the control group, and the responsible nurse used the traditional single evaluation index to start the emergency response system; the patients from January to December 2020 were used as the research group, and the emergency response system was started using e-fMEWS. The inclusion criteria were as follows: (1) hospitalization time ≥24 h; (2) patient ≥14 years old. Exclusion criteria were as follows: (1) patients had cardiopulmonary resuscitation before admission; (2) patients discontinued treatment or were transferred to another hospital during treatment; (3) patients received palliative care; (4) patients were admitted to non-critical wards in grade I of emergency pre-examination and triage. The activation of the rapid response team (RRT), the activation of the cardiorespiratory arrest team, the incidence of cardiac and respiratory arrest, the number of cases of invasive mechanical ventilation, the number of cases admitted to the intensive care unit, the length of hospital stay and the prognosis were compared. Statistical software SPSS 22.0 was used for data analysis.Results:Under the e-fMEWS assessment, compared with the control group, the rate of initiation of the research group decreased by 0.03%. For patients who initiated RRT, the average length of hospital stay was shortened, and the number of in-hospital respiratory cardiac arrest decreased (12.2% vs. 13.2%) and the number of cases transferred to the intensive care unit was less (42.8% vs. 50.6%), the rate of improvement and recovary increased (58.4% vs. 56.1%).Conclusions:The application of e-fMEWS can help clinical nurses to quickly and accurately identify the potential risk of deterioration of the patient's condition. Through early identification of potentially critically ill patients in non-critical units, early intervention and timely treatment can avoid adverse events and improve the patient prognosis.

ObjectiveTo explore the possible mechanism of Chuanxiong (Rhizoma Chuanxiong) & Tianma (Rhizoma Gastrodiae) herbal pair in treating migraines based on AMP-activated protein kinase (AMPK)/transient receptor potential A1 channel (TRPA1) pathway. MethodsForty-eight healthy male SD rats were randomly divided into control group, model group, and Chuanxiong Tianma medication group, with 16 rats in each group. The control group and model group were given 10 ml/kg of normal saline by gavage, while the Chuanxiong Tianma medication group was given 0.675 g/kg of Chuanxiong Tianma herbal pair by gavage, once daily for 8 consecutive days in both groups. Migraime model was performed before the last administration, with subcutaneous injection of 10 ml/kg of normal saline in the control group, and subcutaneous injection of 10 ml/kg of nitroglycerin in the model group and Chuanxiong Tianma medication group. The Von Frey filament was used to measure the periorbital mechanical pain threshold of rats. The enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of calcitonin gene-related peptide (CGRP) in rat serum and cerebrospinal fluid. The nitric oxide (NO) assay kit was used to determine the NO level in serum and cerebrospinal fluid. RT-PCR was usedto detect the mRNA expression levels of immediate-early genes in the trigeminal ganglion of rats (c-Fos), CGRP, transient receptor potential V1 channel (TRPV1), AMPK alpha subunit (PRKAA), and TRPA1. Immunofluorescence was used to detect the number of c-Fos-positive cells in the trigeminal cervical complex (TCC) and the protein expression levels of phosphorylated AMPK (pAMPK) and TRPA1 in the trigeminal ganglion. ResultsCompared to those in the control group, the mechanical stimulation threshold and pAMPK protein expression in the model group decreased, while the levels of CGRP and NO in serum, c-Fos, CGRP, TRPV1 and TRPA1 mRNA levels in the trigeminal ganglion, TRPA1 protein expression, and the number of c-Fos-positive cells in the TCC significantly increased (P<0.05). Compared to those in the model group, the mechanical stimulation threshold and pAMPK protein expression in the Chuanxiong Tianma medication group significantly increased, while the levels of CGRP and NO in serum, c-Fos, CGRP, TRPV1 and TRPA1 mRNA levels in the trigeminal ganglion, TRPA1 protein expression, and the number of c-Fos-positive cells in the TCC significantly decreased (P<0.05). ConclusionChuanxiong Tianma herbal pair may improve migraine symptoms by regulating the AMPK/TRPA1 pathway in the trigeminal ganglion and increasing the mechanical pain threshold.

Roxadustat is the world's first small molecule hypoxia-inducible factor prolyl hydroxylase inhibitor. Its adverse effect of causing hypothyroidism with low thyroid-stimulating hormone (TSH) is relatively rare and manifests subtly in elderly patients with multiple coexisting diseases. This article reports a case of an elderly patient with renal anemia who developed reversible low-TSH hypothyroidism after taking roxadustat for 12 days, with a significant decrease in thyroid hormone levels. After discontinuing roxadustat for 15 days, the thyroid hormone levels gradually returned to normal. Due to the worsening of renal anemia, the patient took roxadustat again, and 9 days later, the thyroid function-related indicators decreased upon re-examination, leading to the initiation of levothyroxine replacement therapy. In conjunction with relevant literature, this article analyzes the adverse reactions that occur during the oral administration of roxadustat in elderly patients with chronic kidney disease, aiming to provide reference for drug treatment of such patients.
