OBJECTIVES: To study the epidemiological characteristics of respiratory syncytial virus (RSV) infection in hospitalized children with community-acquired pneumonia (CAP) in Hebei Province. METHODS: Hospitalized children with CAP who tested positive for RSV and were admitted to Hebei Children's Hospital from various cities and counties across Hebei Province between January 2019 and December 2023 were included in the study. Clinical data were collected and analyzed to assess epidemiological characteristics. RESULTS: The clinical data of 43 978 children with CAP were collected, with an overall RSV detection rate of 25.98%. The detection rate was higher during the implementation of non-pharmaceutical interventions (NPIs) (30.60%) than in the non-NPIs period. Winter and spring were the primary epidemic seasons for RSV each year except in 2022. The detection rate in males (26.62%) was higher than in females (25.06%) (P<0.001). The highest detection rate (59.18%) was found in infants aged 29 days to <1 year. Single RSV infection was more common, with rhinovirus being the most frequent co-infection. CONCLUSIONS The overall RSV detection rate in Hebei Province is influenced by NPIs, being higher during their implementation. RSV predominantly circulates in winter and spring. The detection rate of RSV is higher in males and infants. RSV infection is primarily single, most often co-occurring with rhinovirus.

Objective To explore the influence of continuous thermal exposure on human cognitive performance.It provides solutions for the reduction of cognitive performance caused by high temperature emergency,and reduces the misoperation problems or even safety accidents of astronauts in high temperature emergency.Methods 14 right-handed male subjects were recruited and continuously exposed to four thermal environments of 32℃,35℃,38℃,and 41℃for 150 minutes,during which 5 different cognitive tasks(Posner Cueing Task,Deary-liewald Task,N-back Task,Wisconsin Card Task,Visual Search Task)were continuously performed to obtain relative cognitive performance.At the same time,a portable 2-lead holter was used to continuously capture ECG R signals during the cognitive test.Thereafter,the heart rate variability(HRV)analysis was conducted based on the ECG data,to explore the correlations between nonlinear indices(SD1,Shannon entropy,α2,D2)and the cognitive performance.Results Tresults showed that all nonlinear indexes changed with the exposure time and exposure temperature with certain patterns.In addition,through the correlation analysis between relative cognitive performance and nonlinear indicators,the most relevant indicator is α2(correlation coefficient 0.7).The correlation analysis results showed that the nonlinear index α2 had a U-shaped relationship with relative cognitive performance(correlation coefficient was 0.7).Based on that,a quantitative relationship between α2 and relative cognitive performance was obtained.It is found that when α2 was equal to 0.98,the worst relative cognitive performance was observed.Conclusion This study showed that the HRV nonlinear index α2 could serve as a reliable indicator of the cognitive performance of human during hot exposure,which provided a potential solution for the productivity and health evaluation of astronauts.

Objective To evaluate the in vitro effect of combinations of 5 β-lactam antibiotics with different β-lac-tamase inhibitors on the activity of multidrug-resistant Mycobacterium tuberculosis(MDR-TB),and identify the most effective combination of β-lactam antibiotics and β-lactamase inhibitors against MDR-TB.Methods MDR-TB strains collected in Henan Province Antimicrobial Resistance Surveillance Project in 2021 were selected.The mini-mum inhibitory concentrations(MIC)of 5 β-lactam antibiotics or combinations with different β-lactamase inhibitors on clinically isolated MDR-TB strains were measured by MIC detection method,and the blaC mutation of the strains was analyzed by polymerase chain reaction(PCR)and DNA sequencing.Results A total of 105 strains of MDR-TB were included in the analysis.MIC detection results showed that doripenem had the highest antibacterial activity against MDR-TB,with a MIC50 of 16 μg/mL.MIC values of most β-lactam antibiotics decreased significantly after combined with β-lactamase inhibitors.A total of 13.33％(n=14)strains had mutations in blaC gene,mainly 3 nu-cleotide substitution mutations,namely AGT333AGG,AAC638ACC and ATC786ATT.BlaC proteins Ser111 Arg and Asn213Thr enhanced the synergistic effect of clavulanic acid/sulbactam and meropenem on MDR-TB compared with synonymous single-nucleotide mutation.Conclusion The combination of doripenem and sulbactam has the strongest antibacterial activity against MDR-TB.Substitution mutations of BlaC protein Ser111 Arg and Asn213Thr enhances the sensitivity of MDR-TB to meropenem through the synergy with clavulanic acid/sulbactam.

Based our previous work, twelve purine derivatives were designed and synthesized as dual modulators of GPR119 and DPP-4by conjugating the GPR119 activating and DPP-4 inhibiting fragments with the position 6 and 9 of purine core via an approach of merged pharmacophores. Compound 11, bearing 2-fluoro-4-methylsulphonyl anilide and cyanopyrrolidine moieties, exhibited the most potent GPR119 agonistic activities (EC₅₀ = 0.33 μmol·L^-1, IA = 71.1%) and DPP-4 inhibitory (58.4% inhibition at 10 μmol·L^-1, 21.2% inhibition at 1 μmol·L^-1) activities in the in vitro antidiabetic study. Subsequently, we performed studies on structure activity relationships and molecular docking to guide the further drug design.

To investigate the effect of Fufang yinhua jiedu (FFYH) granules against coronavirus and its potential mechanism, we used Huh7, Huh7.5, H460, and C3A cell lines as in vitro models to evaluate the cytotoxicity and antiviral activity of FFYH by observation of cell pathogenic effect (CPE); and then the inhibitory effect of FFYH on the transcription expression of coronavirus RNA and inflammatory factor mRNA were evaluated by quantitive reverse transcription PCR (qRT-PCR); finally, the inhibitory effect of FFYH on the expression of coronavirus protein and its underlying mechanism against coronavirus were investigated by Western blot and immunofluorescence. Our results indicated that 50% toxic concentration (TC₅₀) FFYH on Huh7, Huh7.5, H460, and C3A cells were 2 035.21, 5 245.69, 2 935.28 and 520 µg·mL^-1, respectively; 50% inhibitory concentration (IC₅₀) of FFYH on HCoV-229E in Huh7 and Huh7.5 cells were 438.16 and 238.54 µg·mL^-1 with safety index (SI) of 4.64 and 21.99, respectively; IC₅₀ of FFYH on HCoV-OC43 in H460 cells was 165.13 µg·mL^-1 with SI of 17.78. Moreover, FFYH not only could inhibit the replication of coronaviruses (HCoV-OC43 and HCoV-229E) through inhibiting the transcription of viral RNA and the expression of viral protein, but also effectively suppress the expression of inflammatory factors interleukin-6 (IL-6), tumor necrosis factor α (TNF-α) and interleukin-8 (IL-8) at mRNA level caused by coronaviruses, which might be associated with the inhibitory effect of FFYH on mitogen-activated protein kinase (MAPK) pathway and the nuclear translocation of nuclear transcription factor-κB (NF-κB). In summary, our results demonstrated that FFYH exhibited a good in vitro anti-coronavirus effect, which provides a theoretical basis for its clinical use in the treatment of anti-coronavirus pneumonia.

ObjectiveTo analyze the clinical characteristics of brucellosis patients from two tertiary hospitals in epidemic and non-epidemic areas. MethodsThe clinical data of 67 brucellosis patients hospitalized in The Affiliated Kashi Hospital of Sun Yat-sen University （Kashi， 53） and The Third Affiliated Hospital of Sun Yat-sen University （Guangzhou， 14） from January 2019 to December 2019 were retrospectively reviewed， including demographic data， medical history， symptoms， signs， laboratory tests and treatment， and the differences between the two groups were compared. ResultsThere were 23 patients in Kashi and 11 patients in Guangzhou with definite epidemiological history， respectively （P = 0.019）. Fever， fatigue and arthralgia were the most common symptoms of brucellosis. In addition to anorexia， the onset symptoms of patients in the two hospitals were roughly the same. The incidence of fever， muscle pain and fever peak was similar， but the symptoms of hyperhidrosis， fatigue， arthralgia and rash in Kashi were more common in Guangzhou. There were cases of hepatosplenomegaly in both hospitals， but there was no obvious superficial lymphedema. Complications occurred in 39（73.6%） and 11（78.6%） patients in Kashi and Guangzhou， respectively， with no statistical difference （P =0.971）， and hepatitis and bone damage were the most common. The incidence of spondylitis （P =0.042） and neurodegenerative brucellosis （P =0.041） in Guangzhou was higher than that in Kashi， and there was no significant difference in other complications. Of the patients in Kashi， 7.5 % were treated with single antibiotics， and 59.7 % were with dual therapy， which were higher than those in Guangzhou （0， 50.0 %）. The proportion of the triple scheme in Guangzhou was higher than that of Kashi （50.0 % vs. 11.3 %）. ConclusionsThe clinical characteristics of brucellosis in different regions are generally similar， but there are some differences in epidemiological history， symptoms， complications and treatment options. The characteristics of local cases should be concerned in clinical practice to reduce misdiagnosis of brucellosis.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

OBJECTIVE: To study the epidemiological features of children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Shijiazhuang, China. METHODS: Based on the information officially announced on the official website of the Health Commission of Hebei Province, epidemiological data were collected from 133 children, aged 0-18 years, who were diagnosed with SARS-CoV-2 infection in Shijiazhuang from January 2 to January 30, 2021. A statistical analysis was performed for general status, regional distribution, presence or absence of clusters, and results of SARS-CoV-2 nucleic acid tests. RESULTS: Among the 133 children with SARS-CoV-2 infection, there were 65 boys and 68 girls, with a male/female ratio of 0.96:1. The youngest age of onset was 3 months and 7 days, and the mean age of onset was (9±5) years. Of all the 133 children, 90(67.7%) were the first confirmed case of SARS-CoV-2 infection among their family members. Of all the children, 108(81.2%) came from the Gaocheng District in Shijiazhuang, among whom 38(28.6%) were from Xiaoguozhuang Village where the first patient with a confirmed diagnosis lived. SARS-CoV-2 nucleic acid test at week 2 after the outbreak showed positive results in 88 children (66.2%), and only 5 children had clinical symptoms before positive SARS-CoV-2 results were obtained. Of all the 133 children, 19(14.3%) were found positive in the first SARS-CoV-2 nucleic acid test after the outbreak, and 70(52.6%) had positive results for ≥4 times. There were 98 school students with infection, among whom 74(75.5%) were the first confirmed case in their family, and among 35 non-school students, 16(45.7%) were the first confirmed case in their family ( CONCLUSIONS Among the children confirmed with SARS-CoV-2 infection in Shijiazhuang, there is a high proportion of children who are the first confirmed case in their family, and the children are mainly distributed in the rural areas of Gaocheng. Most of these children are students, so the prevention and control of cluster infection in schools should be taken seriously. There are often no symptoms before SARS-CoV-2 nucleic acid test, with a low positive rate of the first nucleic acid test, which increases the difficulty of early discovery of the epidemic.

Objective: To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases. Methods: A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases. Results: The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease. Conclusion The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.
