Objective:To analyze the epidemiological characteristics of human respiratory syncytial virus (HRSV) in cases of febrile respiratory syndrome in China from 2010 to 2020.Methods:Based on the sub-project of the National Science and Technology Major Project for Infectious Disease Prevention and Control "Infectious Disease Monitoring Technology Platform", active monitoring of febrile respiratory syndrome cases was conducted in sentinel hospitals in 31 provinces across China (excluding Hong Kong, Macau, and Chinese Taiwan) from January 2010 to December 2020, resulting in the inclusion of 191 441 cases. Clinical specimens of monitored cases were screened for HRSV nucleic acid, and the differences in HRSV detection rates among different age groups, regions, and time periods were analyzed using the χ 2 test/Fisher exact probability method. Results:Among the 191 441 cases of febrile respiratory syndrome in China from 2010 to 2020, the age group M ( Q1, Q3) was 9 (2, 40) years old, with 83 773 cases (43.8%) in the <5 years old group. There were 113 660 males, with a male-to-female ratio of 1.5∶1.0. There were as many as 105 508 cases (55.2%) of scattered children and preschool children. About 70 565 cases (36.9%) lived in the northern region. There were 13 858 HRSV positive cases, with a total positive rate of 7.2%. The positive rate of HRSV detection in the northern population was 5.7% (4 004/70 565), which was lower than that in the southern population (8.2%, 9 854/120 876), and the difference was statistically significant (χ 2=407.4, P<0.001). HRSV was detected in all age groups, with the highest positive rate of 23.9% in the <6 months age group. The month with the highest positive rate was December, and autumn and winter were the main epidemic seasons. Both northern and southern HRSV subtypes were mainly infected with type A, with a low proportion of mixed infections of type A and type B. Conclusion:HRSV is a common pathogen causing respiratory infections in children from 2010 to 2020. It can be detected throughout the year and shows the main peak of prevalence in autumn and winter. The HRSV strain is mainly classified as a type A infection.

Objective:To develop a limb function exercise program for patients on extracorporeal membrane oxygenation (ECMO) and provide theoretical guidance for clinical nursing staff.Methods:A research team was formed to systematically review domestic and international literature on functional exercise for ECMO patients, extracting relevant evidence to form the initial version of the limb function exercise program. From June to July 2023, the Delphi method was used to conduct two rounds of expert consultations with 18 experts from three provinces and municipalities directly under the central government, including Shanghai, Jiangsu, and Shanxi. Based on the experts' feedback, the program items were revised to form the final version of the exercise program.Results:In the first round, 18 experts were consulted, with a valid response rate of 94.44% (17/18); in the second round, 17 experts participated, with a 100.00% (17/17) response rate. The expert authority coefficient was 0.859 in both rounds. The coefficient of variation for each level of indicator in the second round ranged from 0 to 0.160, and Kendall's coefficient of concordance was 0.092 to 0.130 ( P<0.01). The final ECMO patient limb function exercise program consisted of four primary indicators (preparation, assessment, exercise methods, and safety monitoring), 13 secondary indicators, and 44 tertiary indicators. Conclusions:The ECMO patient limb function exercise program developed in this study is scientifically sound and reliable, offering a reference and guidance for the implementation of limb function exercises for ECMO patients.

Objective:To investigate the role of complement C3a receptor in the diabetic nephropathy pathogenesis of db/db mice, and to provide a new target for prevention and treatment of diabetic nephropathy.Methods:Twelve 8-week-old male mice with type 2 diabetes mellitus (db/db mice) and 6 wild-type (db/m) mice were reared in the special pathogen free environment. The mice were grouped into db/m group, db/db group and C3a receptor antagonist group, with 6 mice in each group. db/db model mice were intraperitoneally injected with C3a receptor antagonist (SB290157, 10 mg/kg) once every two days for 8 weeks in C3a receptor antagonist group. Blood and urine samples were collected, and body weight of mice, fasting blood glucose, serum creatinine, blood urea nitrogen, urinary microalbumin/urinary creatinine and urinary N-acetyl-β- D-glucosaminidase (NAG) were detected. Renal tissues were collected, and HE, PAS and Masson stainings were used to observe the pathological changes. Immunohistochemistry, immunofluorescence and Western blotting were used to detect the protein expression levels of C3 and C3a receptor. Western blotting was used to analyze the protein expression levels of kidney injury molecule-1 (Kim-1), α-smooth muscle actin (α-SMA), zonula occluden-1 (ZO-1), vimentin and E-cadherin in renal tissues. Immunofluorescence was used to analyze the protein expression levels and distribution of α-SMA, ZO-1 and Kim-1, and immunohistochemistry was used to analyze the protein expression levels of interleukin-1 (IL-1) and tumor necrosis factor-α (TNF-α). TUNEL assay was used to detect apoptotic cells in renal tissues. Results:Compared with db/m group, body weight, fasting blood glucose, urinary microalbumin/urinary creatinine and urinary NAG in db/db group were significantly higher, while these indicators in C3a receptor antagonist group were slightly lower than those in db/db group (all P<0.01). There were no significant differences in serum creatinine and blood urea nitrogen among the three groups (all P>0.01). Compared with db/m group, db/db group had glomerular hypertrophy, necrosis and exfoliation of renal tubular epithelial cells, and dilation of renal tubules, and C3 and C3a receptor protein expression levels were higher (both P<0.01). Compared with db/db group, C3a receptor antagonist group had less glomerular lesions, mild necrosis of renal tubular epithelial cells and less tubular dilation. Compared with db/m group, the protein expression levels of Kim-1, IL-1 and TNF-α in kidney tissues of db/db group were significantly higher, while Kim-1, IL-1 and TNF-α in C3a receptor antagonist group were significantly lower than those in db/db group (all P<0.01). Compared with db/m group, the protein expression levels of α-SMA and vimentin of renal tubular epithelial cells in db/db group were significantly higher, while the protein expression levels of ZO-1 and E-cadherin were significantly lower (all P<0.01). Compared with db/db group, the protein expression levels of α-SMA and vimentin of renal tubular epithelial cells in C3a receptor antagonist group were significantly lower, and the protein expression levels of ZO-1 and E-cadherin were significantly higher (all P<0.01). Compared with db/m group, the number of apoptotic cells of kidney tissues in db/db group was increased, while the number of apoptotic cells in C3a receptor antagonist group was reduced compared with db/db group. Conclusions:The expression levels of C3 and C3a receptor of kidney tissues in db/db mice are significantly increased. Antagonistic C3a receptor can reduce the body weight, blood glucose, urinary microalbumin/urinary creatinine and urinary NAG, alleviate renal pathological injury, inhibit renal tissue inflammation, apoptosis and renal tubule epithelial-mesenchymal transition in db/db mice.

Eyelid tumor is a serious eye disease that leads to vision loss or even blindness.The similarity between benign and malignant characteristics makes it difficult for ophthalmologists lacking clinical experience to distinguish between them.To address the problem,a method(ResNet101_CBAM)based on two-stage target localization using fully convolutional one-stage object detection(FCOS)and residual network incorporating a dual attention mechanism is proposed to realize the automatic diagnosis of benign and malignant eyelid tumors.FCOS is used to automatically localize the overall contour of the orbit,removing the background and surrounding noise,and then finely localize the tumor lesion inside the orbit.The obtained lesion region is input into ResNet101_CBAM for the automatic diagnosis of benign and malignant eyelid tumors.The experimental results show that the average precision of the target localization algorithm for tumor lesion is 0.821,and that compared with ResNet101,ResNet101_CBAM improves the sensitivity and accuracy in eyelid tumor classification by 4.7%and 3.0%,respectively,indicating that the proposed model has superior performances in the automatic diagnosis of benign and malignant eyelid tumors.

Objective:To study the effects of recombinant human erythropoietin (rhEPO) on cerebral blood flow (CBF) in preterm infants using arterial spin labeling (ASL) magnetic resonance imaging (MRI).Methods:From September 2021 to June 2022, preterm infants (gestational age ≤32 weeks, birth weight ≤1 500 g) admitted to NICU of our hospital within 24 h after birth were randomly assigned into rhEPO group and control group for this prospective study. The rhEPO group was given rhEPO (500 IU/kg iv, once every other day for 2 weeks) within 72 h after birth plus symptomatic supportive treatment. The control group received same amount of normal saline injection. Both groups received brain MRI, diffusion-weighted imaging and ASL at adjusted gestational age of 35~37 weeks and CBF values of interested areas were measured.Results:A total of 85 infants were enrolled, including 40 in the rhEPO group and 45 in the control group. No significant differences existed in the incidences of periventricular-intraventricular hemorrhage, periventricular leukomalacia, focal white matter injury and extensive white matter injury between the two groups ( P>0.05). The CBF values [ml/(100 g·min)] of frontal cortex [left 15.1±3.9 vs. 17.9±3.1, right 15.9 (12.5, 17.8) vs. 18.1(16.1,20.2)], temporal cortex [left 15.8±4.3 vs. 18.6±3.8, right 16.3(13.2,19.4) vs. 18.1(15.7,19.7)], occipital cortex (left 15.8±6.1 vs. 18.8±3.3, right 16.8±5.5 vs. 19.3±4.8), basal ganglia (left 24.7±7.2 vs. 28.7±6.2, right 26.0±7.9 vs. 29.3±6.4) and thalamus (left 32.7±11.8 vs. 37.9±8.6, right 32.1±11.6 vs. 37.6±10.2) in the rhEPO group were significantly lower than the control group ( P<0.05). No significant differences existed of CBF value at the parietal cortex between the two groups ( P>0.05). Conclusions:Early application of rhEPO can reduce CBF in premature infants, which may be related to the neuro-protective effects of EPO.

Objective:To explore the β-amyloid (Aβ) deposition pattern of subjects with the preclinical Alzheimer′s disease (AD), community-derived amnestic mild cognitive impairment (aMCI) and normal cognition (NC) from communities of Shanghai.Methods:According to the inclusion and exclusion criteria, 273 subjects (104 males, 169 females; age (64.2±7.6) years) were recruited from Shanghai community and memory clinics from December 2018 to July 2020. All subjects underwent MRI, 18F-AV45 PET imaging and neuropsychological scale tests and were grouped into AD, aMCI and NC groups based on clinical diagnosis. Differences in demographic information, the neuropsychological scale tests′ scores and positive rate of Aβ deposition among each group were analyzed by one-way analysis of variance or χ2 test. Aβ deposition patterns of AD and MCI groups were analyzed at voxel level, and the differences of Aβ deposition among different groups were compared. Results:Among 273 patients, the positive rates of Aβ deposition in AD, aMCI and NC groups were 84.4%(38/45), 36.4%(20/55) and 23.1%(40/173), respectively ( χ2=58.37, P<0.001). Among AD, aMCI, NC and NC (Aβ-) groups ( n=132), the education years of AD group was the lowest ((9.7±4.6) years; F=8.86, P<0.001). In addition, there were significant differences in the scores of several neuropsychological scale tests among AD, aMCI, NC groups and NC (Aβ-) group ( F values: 27.68-235.50, all P<0.001). Compared with subjects in NC(Aβ-) group, the Aβ depositions in the aMCI and AD groups were widely distributed in the whole cerebral cortex; and AD group had higher Aβ deposition in bilateral frontal, parietal, temporal, occipital lobe, cingulate gyrus and precuneus than aMCI group. Conclusions:The positive rate of Aβ deposition in the preclinical AD population from the Shanghai community is obtained. There are significant different Aβ deposition patterns in subjects at different stages of AD.

ObjectiveTo study the effects of Toddalia asiatica alcohol extract on autophagy and apoptosis of non-small cell lung cancer A549 cells, and to explore its possible mechanism. MethodA549 cells were cultured in vitro. Cell counting kit-8 (CCK-8) was used to detect the proliferation of A549 cells, and cell survival rate was calculated to screen the drug concentration. The apoptosis in each dose group and that after the use of 3-methyladenine (3-MA), an autophagy inhibitor, were detected by flow cytometry combined with Annexin V-FITC/PI double staining. Western blot was used to detect the expression levels of apoptosis-related proteins such as B cell lymphocytoma-2(Bcl-2), Bcl-2-associated X protein(Bax), microtubule-associated protein 1 light chain 3 (LC3), cleaved cysteinyl aspartate-specific protease-3 (cleaved Caspase-3), activated poly (Adenosine diphosphate) ribonucleotide polymerase (cleaved PARP1), PARP1, activated death activator (t-Bid), Bid, and ubiquitin-binding protein p62 in each group and those after the use of 3-MA. ResultCompared with the conditions in the control group, the cell survival rate in 0.25 g·L-1 group (P<0.05), and 0.5, 1, 2, 4 g·L-1 groups (P<0.01) was decreased after 24 h intervention. Additionally, the cell survival rate was reduced in a concentration-dependent manner at 48 h and it was less than 10% at 4 g·L-1 (P<0.01). Compared with the conditions in the control group, the total apoptosis rate in 0.5 g·L-1 group was increased (P<0.05), and the apoptosis rate in 1 and 2 g·L-1 groups was also increased (P<0.01). Compared with the 2 g·L-1 group and 3-MA group, the 3-MA combined with T. asiatica alcohol extract had significantly decreased apoptosis rate (P<0.01). Compared with the conditions in the control group, elevated expression of pro-apoptotic proteins cleaved PARP1, Bax and t-Bid in 1 and 2 g·L-1 groups (P<0.05, P<0.01), and reduced expression of Bid in the 2 g·L-1 group (P<0.01) were found. Compared with the conditions in the control group, the expression of anti-apoptotic protein Bcl-2 (P<0.05, P<0.01) and the level of p62 (P<0.01) were down-regulated in 0.5, 1, 2 g·L-1 groups, while the level of LC3 Ⅱ protein was up-regulated (P<0.01), with certain concentration dependence. ConclusionT. asiatica alcohol extract could significantly inhibit the proliferation of A549 cells, which might be related to promoting autophagy and inducing apoptosis.
