Objective To explore the value of dynamic monitoring of the neutrophils/lymphocyte ratio ( NLR ) in peripheral blood for the prognosis of patients with bloodstream infection ( BSI ). Methods A retrospective study was conducted. 205 patients who were≥18 years old, their length of hospital stay>24 hours, and they were treated in the China-Japanese Friendship Hospital from January 2013 to October 2014 were enrolled. According to the 28-day survival, the patients were divided into survival group ( n=160 ) and death group ( n=45 ). The white blood cell ( WBC ), neutrophils count ( NEU ), neutrophils ratio ( Neut%), lymphocyte count ( LYM ), lymphocyte ratio ( Lym%), and NLR in peripheral blood were recorded at 1, 3, 7 days after admission. Receiver-operating characteristic curve ( ROC ) was plotted for evaluating the value of these factors on the 28-day prognosis, and logistic regression analysis was used to evaluate the risk factors for predicting the outcome. Results ①On the 1st day, WBC, NEU, Neut%, NLR, and procalcitonin ( PCT ) in the death group were significantly higher than those in the survival group [ WBC (×109/L ):15.28±8.23 vs. 11.58±6.55, NEU (×109/L ):13.34±7.53 vs. 10.03±5.31, Neut%:0.886±0.076 vs. 0.845±0.102, NLR:21.20 ( 13.10, 28.80 ) vs. 12.08 ( 6.81, 20.47 ), PCT (μg/L ):3.13 ( 0.85, 10.12 ) vs. 1.34 ( 0.36, 5.81 ), P<0.05 or P<0.01 ], while hemoglobin ( Hb ), platelet count ( PLT ), albumin ( ALB ) content were significantly lower than those of the survival group [ Hb ( g/L ):86.09±19.83 vs. 107.89±22.82, PLT (×109/L ):157.51±117.81 vs. 195.44±97.28, ALB ( g/L ):24.11±6.94 vs. 31.99±6.89, P<0.05 or P<0.01 ]. On the 3rd day and 7th day, WBC, NEU and NLR in the death group were significantly higher than those of the survival group [ WBC (×109/L ):16.61±10.25 vs. 8.91±4.93, 16.05±9.46 vs. 8.79±4.45; NEU (×109/L ): 14.15±9.98 vs. 6.97±4.64, 14.36±9.03 vs. 6.59±4.07; NLR: 24.13 ( 8.49, 38.26 ) vs. 5.52 ( 3.58, 8.87 ), 17.74 ( 10.74, 32.85 ) vs. 4.35 ( 2.78, 7.27 ), all P<0.01 ], and the LYM and Lym%were significantly lower than those in the survival group [ LYM (×109/L ):0.61 ( 0.38, 1.04 ) vs. 1.05 ( 0.78, 1.43 ), 0.69 ( 0.35, 0.92 ) vs. 1.37 ( 0.93, 1.76 );Lym%:0.039 ( 0.024, 0.101 ) vs. 0.135 ( 0.094, 0.186 ), 0.056 ( 0.033, 0.082 ) vs. 0.170 ( 0.108, 0.237 ), all P<0.01 ].②It was shown by ROC curve that the maximum area under the ROC curve ( AUC ) of WBC, NEU, Neut%, LYM, Lym%, and NLR about prognosis of BSI were observed on 7 days ( 0.777, 0.819, 0.905, 0.755, 0.880, 0.887 ). Based on Neut%>0.855 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 78.8%, specificity 89.1%, respectively. When Lym%<0.088 on the 7th day as a predictor of cut-off value of death on 28 days, the sensitivity was 89.5%, and specificity was 83.9%. When NLR>10.34 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 81.8%, and specificity was 91.0%.③Survival analysis showed that the 28-day survival rate in the patients with 7-day NLR<10.34 was significantly higher than that in those with 7-day NLR>10.34 ( 95.0%vs. 34.1%,χ2=82.650, P=0.000 ).④It was shown by multi-factor logistic regression analysis that the levels of 1-day Hb and 7-day NLR were the independent prognostic predictors of 28-day mortality [ Hb: odds ratio ( OR ) = 0.946, 95% confidence interval ( 95%CI ) = 0.913-0.981, P = 0.003; 7-day NLR:OR=34.941, 95%CI=8.728-139.884, P=0.000 ]. Conclusions The trend of changes in NEU, LYM and NLR as shown by repeated routine blood examinations contributes to prediction of the outcome of patients with BSI. The levels of 1-day Hb and 7-day NLR are the independent prognostic predictors for 28-day mortality.

Objective To preliminarily understand the infection of Chikungunya virus (CHIKV) in Cangyuan County, a southern border area of Yunnan Province, and provide a reference basis for the prevention and control of Chikungunya fever. Methods In April 2020, a total of 400 serum samples from individuals seeking medical care at the People's Hospital of Cangyuan County in Yunnan Province were collected. Among these, 121 samples were from healthy individuals undergoing physical examinations, and 279 samples were from patients with fever. The serum samples collected underwent CHIKV neutralizing antibody testing using a serum micro-neutralization assay. Real-time fluorescence quantitative RT-PCR was used to detect CHIKV nucleic acid in the samples, followed by analysis of the test results. Results The results of neutralizing antibodies showed that 18 of the 400 human serum samples were positive for neutralizing antibodies against CHIKV, with an overall positivity rate for serum samples of 4.5% (18/400). Among the 279 serum samples collected from patients with fever, 18 were positive for neutralizing antibodies against CHIKV, with a positive rate of 6.45% (18/279), and the neutralizing antibody titers ranged from 1∶10 to 1∶320. The results of 121 healthy human serum samples were negative for neutralizing antibodies against CHIKV. The results of real-time fluorescence quantitative RT-PCR showed that 3 of the 400 human serum samples were positive for CHIKV nucleic acid, and the positive rate was 0.75% (3/400). Among the 279 serum samples collected from patients with fever, 3 samples were positive for CHIKV nucleic acid, with a positive rate of 1.08% (3/279), and Ct values ranged from 36.58 to 37.74. While all healthy human serum samples were negative for CHIKV nucleic acid. Conclusions The findings indicate that infection of CHIKV exists in the population of Cangyuan County, a southern border area of Yunnan Province, and an outbreak of the disease is occurring. Therefore, it is necessary to strengthen the monitoring, prevention, and control of CHIKV in this area.

Objective This study aims to comprehensively investigate the molecular characteristics of the predominant circulating Dengue virus type 1 (DENV-1) during the 2019 Dengue fever outbreak in Xishuangbanna, providing an essential insight to support the prevention and control of dengue fever in the local area. Methods A Dengue virus type 1 (DENV-1) strain, designated as JHS45, isolated from the blood of a febrile patient in Xishuangbanna in 2019, underwent a process of inoculation and cultivation in C6/36 cells. Second-generation sequencing was employed to capture the viral genetic sequence. Bioinformatics software, including CLC, was used for assembling the sequencing data. Sequentially, sequence alignment, construction of a phylogenetic tree, and analysis of amino acid sites were conducted using software such as Lasergene and MEGA6.1. Results Cytopathic effects of JHS45 appeared in C6/36 cells after 6 days. After sequencing and assembly, a 10 687-nucleotide (nt) long sequence of the JHS45 virus was obtained (GenBank accession number: OR593353). Genetic evolutionary analysis revealed that the JHS45 virus formed an evolutionary branch with DENV-1 genotype I viruses prevalent in Xishuangbanna, Guangzhou, Henan, and Zhejiang in China during 2019, as well as the DENV-1 genotype I virus prevalent in Thailand in 2013, with nucleotide homology of 97.6% to 99.9% and amino acid homology of 99.1% to 100%. Further analysis revealed that the JHS45 strain shared a smaller evolutionary branch with the DENV-1 genotype I viruses prevalent in Xishuangbanna (MW386863) and Guangzhou (MW261839) in 2019, showing the highest homology with nucleotide and amino acid homology of 99.9% and 100%, respectively. Amino acid differential site analysis between the JHS45 strain and the DENV-1 prevalent in Xishuangbanna since 2015 revealed 40 amino acid differential sites in the coding region of the JHS45 virus, primarily concentrated in the NS3 and NS5 regions of non-structural proteins. Conclusion The comprehensive analysis of the JHS45 strain's whole genome sequence indicates it is a DENV-1 genotype I virus. The genetic evolutionary relationship between this Xishuangbanna dengue fever outbreak is closely related to the prevalent virus strains in Xishuangbanna, Guangzhou, Henan, and Zhejiang. These findings provide a robust scientific foundation for monitoring dengue fever outbreaks, conducting virus evolution studies, and shaping effective prevention and control strategies, not only within Yunnan Province but also on a broader scale throughout China.
