Coronavirus disease-19 (COVID-19) has reached pandemic status, and its pathogeny is the 2019 novel coronavirus (2019-nCoV).2019-nCoV mainly causes human respiratory infection and pulmonary inflammation; however, some COVID-19 patients are found to present viral conjunctivitis.Bilateral viral conjunctivitis is an initial symptom in some other cases.It is therefore, vital to understand whether the eye can be directly infected by the virus, as well as the consequences of the viral infection in the ocular tissue.2019-nCoV invades human cells primarily by binding to the angiotensin-converting enzyme 2 (ACE2) receptors.ACE2 expresses, not only in the lungs, kidneys, and cardiovascular system, but also in human conjunctiva, cornea, aqueous humor, and retina.Therefore, it is crucial to comprehensively expand the present understanding of the COVID-19 infection mechanism and pathogenesis by clarifying the distribution of ACE2 in the eye.ACE2 is not only the receptor of 2019-nCoV, but also a key enzyme in the renin-angiotensin system (RAS). RAS, which appears relatively independent in the eye, plays a modulating role and is associated with many common eye diseases.This article reviews the distribution and clinical significance of ACE2 in ocular tissues.

Objective: To investigate the epidemilogical characteristics of pulmonary tuberculosis in Huzhou City, Zhejiang Province from 2014 to 2023, so as to provide the basis for formulating prevention and control measures for the construction of "TB-free city". Methods: The data of pulmonary tuberculosis cases in Huzhou City from 2014 to 2023 was collected through the Infectious Disease Reporting Management System of Chinese Disease Prevention and Control Information System. The onset time, region, and population distribution characteristics of the cases were described. Results: A total of 11 598 cases of pulmonary tuberculosis were reported in Huzhou City from 2014 to 2023, with an average annual incidence of 37.42/105. The reported incidence decreased from 47.50/105 in 2014 to 28.36/105 in 2023 (P<0.05), with an annual decline rate of 5.57%. There were 6 304 etiological positive cases, accounting for 54.35%. The peak season for pulmonary tuberculosis cases was from March to September, with the highest seasonal ratio of 112.48% in May. The average annual reported incidence rates in Anji County and Changxing County were relatively high (46.14/105 and 41.15/105). The reported incidence rate of pulmonary tuberculosis in Huzhou City increased with age (P<0.05), peaking at 97.36/105 in the group aged 75 to <80 years. There were 7 991 male pulmonary tuberculosis cases and 3 607 female cases, with a male-to-female ratio of 2.22∶1. The average annual incidence rates of pulmonary tuberculosis was higher in males than in females (50.39/105 vs. 23.87/105). Farmers were the primary occupation affected, with 6 350 cases accounting for 54.75%. Conclusions The reported incidence rate of pulmonary tuberculosis in Huzhou City decreased from 2014 to 2023, with a high incidence in spring and summer. The incidence rates in Anji County and Changxing County were higher than Huzhou City's average. Male, elderly residents and farmers were the key populations for pulmonary tuberculosis prevention and control.

Objective To analyze the distribution characteristics and drug resistance of nontuberculous mycobacteria(NTM),and to provide guidance for the selection of targeted agents in clinical treatment. Methods The clinical data of inpatients in our hospital from April 2019 to February 2021 were collected,the culture and strain identification of non tuberculosis mycobacteria were carried out,the drug sensitivity test of anti tuberculosis drugs was carried out,and the drug resistance of non tuberculosis mycobacteria to first-line anti tuberculosis drugs was analyzed. Results A total of 1 326 strains of mycobacterium were isolated,including 1 154(87.03%)strains of mycobacterium tuberculosis and 172(12.97%)strains of non-mycobacterium tuberculosis.Nine species of nontuberculous mycobacteria were detected,including slow-growing mycobacteria such as Mycobacterium kansasii and Mycobacterium avium-intracellulare complex,belonging to Groups I-III,and fast-growing mycobacteria such as Mycobacterium chelonae and Mycobacterium smegmatis,belonging to Group IV. Among them , Mycobacterium avium-intracellulare complex and Mycobacterium chelonae were dominant,accounting for 26.16%and 36.63%,respectively.Drug susceptibility tests showed that the resistance rate of Mycobacterium avium-intracellulare complex to streptomycin was 100.00%,the drug resistance rate of Mycobacterium chelonae to isoniazid,rifampicin and streptomycin was 100.00%,and the drug resistance rate of Mycobacterium smegmatis and Mycobacterium abscessus to most antibacterial drugs was 100.00%.The resistance rate of major NTM bacteria to clarithromycin was relatively low.There was no statistically significant difference in the susceptibility rates of slow and fast-growing mycobacteria to isoniazid and clarithromycin(P>0.05) ; The susceptibility rates of slow-growing mycobacteria to amikacin,clarithromycin and rifambutin were 62.86%,92.86%and 72.86%,all above 50.00%.The susceptibility rate of the fast-growing mycobacteria to clarithromycin was also more than 50.00%,being 87.25%.The susceptibility rate of slow-growing mycobacteria to other antibiotics was higher than that of fast-growing mycobacteria(P<0.05).The drug resistance of Mycobacterium tuberculosis to first-line anti tuberculosis drugs was significantly lower than that of non Mycobacterium tuberculosis(P<0.05). Conclusion Non-tuberculous mycobacteria have high drug resistance,especially fast-growing mycobacteria,so drug susceptibility tests are of great value in clinical treatment.

Objective: To investigate the association between the internal exposure levels of phthalic acid esters (PAEs) and executive function (EF) of preschool children. Methods: Between October 2008 and October 2010, pregnant women who accepted pregnancy health care services in four municipal medical and health institutions in Ma'anshan city, Anhui Province, were recruited as study objects. A total of 5 084 pregnant women and 4 669 singleton live births were enrolled in this cohort. The follow-up study was conducted from April 2014 to April 2015. A total of 3 725 data-completed preschool children aged 3 to 6 years older entered in this study. The method of analysis seven metabolites of phthalates in urine was high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) and divided objects into low (P₀-P₂₄), medium (P₂₅-P₇₄) and high (P₇₅-P₁₀₀) groups according to their exposure concentrations. To investigate the executive function of preschool children, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the etiology association between the phthalate metabolites levels and preschool children's executive function. Results: In this study, 53.6% (1 997/3 725) of preschoolers were boys, children's age was (51.5±5.6) months. The detection rates of seven phthalate esters were: mono-n-methyl phthalate (MMP) was 99.89% (3 721/3 725); mono-ethyl phthalate (MEP) was 99.97% (3 724/3 725); mono-benzyl phthalate (MBzP) was 69.10% (2 574/3 725); mono-butyl phthalate (MBP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono- (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) were 100.00% and mono-ethylhexyl phthalate (MEHP) was 99.95% (3 723/3 725). The median concentrations of the seven phthalate metabolites were: 17.71, 15.36, 0.07, 155.24, 10.73, 14.67, 3.59 µg/L, respectively. The median concentrations corrected by urinary creatinine were 29.65, 26.65, 0.12, 257.73, 17.94, 24.80, 6.27 µg/g Cr, respectively. The P₂₅ and P₇5 concentration of the total PAEs metabolites corrected by urinary creatinine were 1.20 µmol/g Cr and 3.04 µmol/g Cr. After adjusted the relevant demographic information: children sex, children age in month, maternal age, parental education levels, household exposure to secondhand smoke and whether the child is the only child as confounds, multivariate logistic regression model showed that the risk of inhibitory self-control index (ISCI) dysplasia in MEHHP high concentration group and MEOHP high concentration group were 1.71 and 1.54 times (OR=1.71, 95% CI: 1.11-2.62; OR=1.54, 95% CI: 1.01-2.34) than in low concentration group. The risk of ISCI dysplasia in total PAEs metabolites high concentration group was 1.55 times (OR=1.55, 95% CI: 1.00-2.38) than in low concentration group. Conclusion Phthalates exposure may damage the executive function of preschool children.
