OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets， followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established ， and the zebrafish were treated with L. ruthenicum Murr. extract （LRME） at concentrations of 0.1， 0.2 and 0.4 mg/mL， respectively； 24 h later， behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 （IL-6）， IL-1β， IL-10， tumor necrosis factor-α （TNF-α）]， oxidative stress markers [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， catalase （CAT）]， and neurotransmitters [5- hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， glutamic acid （Glu）， dopamine （DA）， and norepinephrine （NE）] were measured. The protein expression levels of protein kinase B1 （AKT1）， phosphorylated AKT1 （p-AKT1）， epidermal growth factor receptor （EGFR）， B-cell lymphoma 2 （Bcl-2）， sarcoma proto-oncogene，non-receptor tyrosine kinase （SRC）， and heat shock protein 90α family class A member 1 （HSP90AA1） in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these， apigenin， naringenin and others were recognized as core active compounds， while AKT1， EGFR and others served as key targets； EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-， medium-， and high-dose groups were 54.60%， 69.03% and 77.97%， 开发。E-mail：hjp_yft@163.com respectively， while the inhibition ratios of locomotor distance were 0.57， 0.83 and 0.95， respectively. Compared with the model group， the number of resting counts， resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups （P＜0.05）. Neuronal damage in the brain was alleviated. Additionally， the levels of IL-6， IL-1β， TNF-α， MDA， Glu， DA and NE， as well as the protein expression levels of AKT1， p-AKT1， EGFR， SRC and HSP90AA1， were markedly reduced （P＜0.05）， while the levels of IL-10， SOD， GSH-Px， CAT， 5-HT and GABA， as well as Bcl-2 protein expression， were significantly elevated （P＜0.05）. CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects， and its specific mechanism may be related to the regulation of inflammatory responses， oxidative stress， neurotransmitter balance， and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

Objective: To investigate the epidemiological characteristics of pulmonary tuberculosis (PTB) among residents aged 60 years and older in Yangzhou City, Jiangsu Province from 2013 to 2022, so as to provide the evidence for the improvement of PTB prevention and control measures in this population. Methods: Data of PTB cases aged 60 years and older in Yangzhou City from 2013 to 2022 were collected from the Chinese Disease Prevention and Control Information System. The temporal, population, and regional distribution characteristics of PTB cases were analyzed using the descriptive epidemiological method. Results: A total of 8 726 PTB cases aged 60 years and older were registered in Yangzhou City from 2013 to 2022, including 4 167 cases positive for pathogenic tests, with a positive rate of 47.75%. The registered incidence rates and the positive rates of pathogenic tests of PTB among residents aged 60 years and older in Yangzhou City showed downward trends from 2013 to 2022 (both P<0.05). The average annual registered incidence rate of PTB was 83.95/105, and the average annual registered incidence rate of PTB positive for pathogenic tests was 40.09/105. The average annual registered incidence rate of PTB in males was higher than that in females (138.57/105 vs. 31.76/105, P<0.05). The registered incidence rate of PTB showed an increasing trend with age (P<0.05), with the highest rate observed in the age group of 75-<80 years (110.37/105). The top three regions with the highest average annual registered incidence rates of PTB were Jiangdu District (94.34/105), Baoying County (91.61/105) and Hanjiang District (84.93/105). Conclusions The registered incidence of PTB among residents aged 60 years and older in Yangzhou City showed a downward trend from 2013 to 2022. Particular attention should be payed to males, residents aged 75- <80 years, and the elderly in Jiangdu District and Baoying County.

Sexual dimorphism in the brain underlies behavioral differences between sexes. The bed nucleus of the stria terminalis (BNST) is a complex nucleus that differs between males and females, but the sexual dimorphism in cytoarchitecture and the connectome of its oval subdivision (ovBNST) remains largely unexplored. By combining snRNA-seq and transgenic labeling, we found a higher density of ovBNST proenkephalin (ovBNST^PENK) neurons in male than female mice. Anatomically, we virally mapped the efferents and afferents of ovBNST^PENK neurons, finding reciprocally dimorphic connections with the hypothalamus and striatum. Gene enrichment analysis suggests that ovBNST^PENK neurons are modulated by the upstream dopamine pathway. Functionally, by applying caspase-3-mediated depletion of ovBNST^PENK neurons, we found that loss of these neurons enhanced locomotor activity in male but not female mice, without altering the anxiety-like phenotypes in either sex. Our study may pave the way for a better understanding of the anatomical and functional profiles of ovBNST^PENK neurons from a sexually dimorphic perspective.

Information on patients with rifampicin-resistant pulmonary tuberculosis (RR-PTB) in Yangzhou City from 2012 to 2020 was obtained from the Information System of the Chinese Center for Disease Control and Prevention. The epidemic characteristics of RR-PTB patients were analyzed by using χ2 test. The average annual registered incidence rate of RR-PTB patients in Yangzhou City from 2012 to 2020 was 0.57/100 000, and the difference between the registered incidence rates in each year was statistically significant ( χ2=29.326, P<0.001). The proportion of re-treated patients (64.8%) was higher than that of newly treated patients (35.2%, χ2=50.593, P<0.001). The registered incidence rate in males (0.91/100 000) was higher than that in females (0.24/100 000, χ2=80.566, P<0.001). The age distribution showed that the highest incidence rate was in the age group≥60 years (0.96/100 000) and the lowest was in the age group 0-<45 years (0.31/100 000, χ2=55.853, P<0.001). From 2012 to 2020, Baoying County had the largest number of registered RR-PTB patients (44 cases), and its registered incidence rate (0.64/100 000) was only lower than that of Guangling District (0.98/100 000). The registered incidence rate of RR-PTB patients in Baoying County during 2016—2020 also increased significantly compared to 2012—2015 ( P=0.001). Logistic regression was used to analyze the factors related to the treatment outcome of RR-PTB patients. The results showed that patients aged≥60 years and those classified as the re-treatment were risk factors for successful treatment of RR-PTB patients ( P<0.05). In summary, males, people aged≥60 years, patients classified as the re-treatment, and residents of Baoying County should be the key populations for RR-PTB epidemic prevention and control in Yangzhou City.

Objective: To evaluate the effectiveness of recombinant Mycobacterium tuberculosis fusion protein skin test (EC-ST) in screening for latent tuberculosis infection (LTBI) among HIV/AIDS patients, so as to provide insights into the applicability of EC-ST in LTBI screening among HIV/AIDS patients. Methods: From April to June 2023, HIV/AIDS patients under management and treatment in Yangzhou City, Jiangsu Province, were selected as study subjects. Basic information was collected through questionnaire surveys. LTBI was screened by EC-ST and interferon-gamma release assay (IGRA). Taking IGRA results as the diagnostic standard, the positive rate, sensitivity, specificity and consistency rate of EC-ST, and the impact of CD4+T lymphocyte (CD4) counts on the screening effect of EC-ST were analyzed. Results: A total of 523 HIV/AIDS patients were screened, including 458 males (87.57%) and 65 females (12.43%). The median age was 48.00 (interquartile range, 21.00) years. The positive rate of EC-ST was 7.27% and the positive rate of IGRA was 7.46%, with no statistically significant difference (P>0.05). The consistency rate of the two methods was 94.84%, and the Kappa value of 0.621 (95%CI: 0.489-0.752, P<0.05). The sensitivity of EC-ST was 64.10% and the specificity was 97.31%. Comparing the groups with CD4 counts <500 and ≥500 cells/μL, the consistency rates of the two methods were 95.32% and 94.44%, and the Kappa values were 0.568 and 0.650, respectively (both P<0.05). There were no statistically significant differences in the positive rates, sensitivity, and specificity of EC-ST (all P>0.05). Comparing the groups with CD4 counts <200 and ≥200 cells/μL, the consistency rates of the two methods were 96.55% and 94.62%, and the Kappa values were 0.648 and 0.619, respectively (both P<0.05). There were no statistically significant differences in the positive rates, sensitivity, and specificity of EC-ST (all P>0.05). Conclusion The effectiveness of EC-ST in screening for LTBI among HIV/AIDS patients is consistent with that of IGRA and is not affected by CD4 counts.

Background Tributyl phosphate (TBP) is widely used as an organophosphate flame retardant. However, there are limited studies on the toxicity of TBP to aquatic organisms at low levels of exposure. Objective To investigate the effects of TBP on early development of zebrafish (Danio rerio). Methods Zebrafish embryos were randomly divided into four groups at 2 h post-fertilisation (2 hpf), namely, the 0.01% dimethyl sulfoxide (DMSO) control group and TBP exposure groups (0.02, 0.2 and 2 μg·L⁻¹). The exposure time was from 2 hpf to 120 hpf and the hatching rate, malformation rate, heart rate and body length of zebrafish embryos at 72 hpf, the frequency of tail curling at 24-29 hpf, the locomotor ability at 96 hpf and the survival rate at 120 hpf were evaluated, respectively. The whole-body triiodothyronine (T₃) and tetraiodothyronine (T₄) levels of juvenile fish were measured by enzyme immunoassay at the end of the infection, and the expression levels of hypothalamic-pituitary-thyroid axis (HPT) and neurodevelopmental-related genes were detected by quantitative real-time PCR (q-PCR). Results The heart rates of zebrafish embryos were significantly decreased in all TBP-treated groups (P<0.001), the survival rates of the 0.02 and 2 μg·L⁻¹ TBP groups were significantly decreased (P<0.05), and the malformation rate of the 2 μg·L⁻¹ treated group was significantly increased (P<0.05), which was mainly manifested by pericardial oedema. The frequency of tail curling of zebrafish embryos in all groups reached the highest at 25 hpf, which was significantly lower (P<0.001) in all exposure groups than in the control group (P<0.001). In the locomotor behaviour experiments, the swimming speed of zebrafish larvae in the dark cycle was significantly decreased in the 0.02 and 0.2 μg·L⁻¹ TBP groups (P<0.05), and similar results were found for the light cycle in the 0.2 and 2 μg·L⁻¹ TBP groups (P<0.05). Compared with the control group, the T₃ level of zebrafish juveniles in the 0.2 μg·L⁻¹ TBP group increased significantly (P<0.05). The q-PCR results showed that the expression levels of HTP axis-related genes [thyroid hormone receptors (trα, \begin{document}$tr\beta $\end{document}), thyroglobulin (tg), and sodium/iodide co-transporter (nis)] were significantly down-regulated in the exposure groups, the expression level of transthyretin (ttr) was significantly up-regulated in the 0.02 μg·L⁻¹ TBP group, and the iodothyronine deiodinase 2 (dio2) expression level was significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05); the neurodevelopment-related gene acetylcholinesterase (ache) was significantly down-regulated in the exposure groups, and the expression levels of myelin basic protein (mbp) and Elav like neuron-specific RNA binding protein 3 (elavl3) were significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05). Conclusion TBP exposure can lead to early developmental abnormalities in zebrafish, manifested as developmental toxicity, thyroid endocrine disruption and neurotoxicity during hatching and early juvenile stages.
