ObjectiveTo investigate the association between maternal infection with the SARS-CoV-2 Omicron variant during pregnancy and common infant illnesses and neurodevelopment. MethodsA cohort study was designed, selecting 113 pregnant women from Shanghai’s Pudong New Area who tested positive for SARS-CoV-2 by nasal swab reverse transcription-polymerase chain reaction (RT-PCR) and were transported to medical institutions for isolation treatment between March and May 2022. These women constituted the pregnancy infection group. Concurrently, 226 pregnant women from the same region and time period who did not infect with SARS-CoV-2 were selected as the control group. Both groups were followed up until delivery and their offspring’s one year old. The differences in the risk of common infant illnesses and the level of infant’s neurodevelopment at age one were compared between the two groups. ResultsNo significant difference was found in the incidence of common illnesses before one year of age between the pregnancy infection group and the control group. Additionally, no significant differences were found in any domain scores of the ASQ-3 between the two groups. ConclusionMaternal infection with SARS-CoV-2 Omicron variant during pregnancy was not statistically significant correlated with common infant illnesses in infancy and neurodevelopment at age one.

ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates （P<0.05）. Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r₀=5, α=0.3, β₁=0.08, β₂=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (r_t≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

OBJECTIVE To provide a reference for optimizing and promoting the quality standards of Shechuan naolitong granules. METHODS Fifteen batches of Shechuan naolitong granules were used as samples to establish HPLC fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition）. Similarity evaluation and common peak identification were performed， and orthogonal partial least squares discriminant analysis （OPLS-DA） was used to assess quality differences among different batches and to screen quality differential components. Using salvianolic acid B（SAB） as the internal reference， quantitative analysis of multi-components by single-marker （QAMS） was developed to simultaneously determine geniposidic acid （GA）， chlorogenic acid （CA）， vaccarin （VA）， ferulic acid （FA） and senkyunolide I （SI）. The results were compared with those obtained by the external standard method. RESULTS A total of 13 common peaks were identified in the HPLC fingerprints of 15 batches of samples， and the similarities of the spectra were all above 0.96. Seven chromatographic peaks were identified as GA （peak 3）， CA （peak 6）， VA （peak 8）， FA （peak 9）， SI （peak 11）， SAB（peak 12） and TA（peak 13）. OPLS-DA indicated that the differential quality markers among 15 batches were peaks 5， 11 （SI）， and 12 （SAB）.Using SAB as the internal reference， the relative correction factors for GA， CA， VA， FA and SI were calculated as 1.058 4， 0.594 3， 0.643 3， 0.342 7 and 0.262 8， respectively. The mean content of GA， CA， VA， FA， SI and SAB across the 15 batches of samples were 0.155 0， 0.085 4， 0.140 3， 0.071 8， 0.072 7， 1.276 3 mg/g， respectively， showing no significant difference compared with the ESM （P＞0.05）. CONCLUSIONS The established HPLC fingerprint and QAMS are simple， efficient and economical， providing a reference for the quality control and further development of Shechuan naolitong granules.

Objective: To determine the heterogeneity for caries prevention service preferences among children in Anhui Province, so as to provide reference for the promotion and popularization of caries prevention services for school age children. Methods: Based on a discrete selection experiment, a face to face questionnaire survey was administered using a multi stage sampling method among 785 parents with children 3-12 years of age who were hospitalized in the stomatology clinics of 7 prefectures and cities in Anhui Province from October 2021 to October 2022. A mixed Logit model was used to evaluate caries prevention service preferences for children. Results: Four discrete choice experiment attributes included in the study were statistically significant for choice preference ( P <0.05). Compared with the control group, parents with a high school education or above preferred caries prevention services with 70%-<80% preventive effectiveness, 2-<5 and <2 km from the service point, and a high service cost ( β =0.38, 1.66, 1.64, 0.00); female parents preferred preventive services with 70%-<80% preventive effectiveness and a high service cost ( β =0.35, 0.01 ); parents of children <7 years of age preferred services with 70%-<80% preventive effectiveness ( β =0.75); parents of children with oral health preferred preventive services during winter and summer vacations ( β =-0.28); parents of children with caries preferred preventive services with a high cost per denticle ( β =0.00)( P <0.05). Conclusions Parents with different education levels, gender, child age, and oral health status have heterogeneity in dental caries prevention service preferences. The provision of targeted and precise services can improve the participation and coverage of caries prevention services for school age children.

Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.

Methods: The deaths of the four diseases in Xiaoshan District from 2015 to 2021 were collected from Zhejiang Provincial Chronic Diseases Surveillance Information Management System. The crude mortality, standardized mortality and probability of premature death were calculated. The trends in mortality and probability of premature death were analyzed using average annual percent change (AAPC), and the attainment of probability of premature death due to the four diseases was evaluated using the targets of probability of premature death control in 2025 and 2030. Results: Totally 36 130 deaths due to the four diseases were reported in Xiaoshan District from 2015 to 2021. The crude mortality and standardized mortality were 445.20/105 and 237.81/105, which appeared a tendency towards a decline (AAPC=-1.427% and -4.051%, both P<0.05), and the probability of premature death decreased from 9.99% to 7.82%, (AAPC=-4.123%, P<0.05). The standardized mortality of malignant tumors, cardio-cerebrovascular diseases and chronic respiratory diseases appeared a tendency towards a decline (AAPC=-3.017%, -4.999%, and -6.024%, all P<0.05), while there was no significant trend in the standardized mortality of diabetes (AAPC=-0.847%, P>0.05). The probability of premature death due to malignant tumors appeared a tendency towards a decline (AAPC=-4.167%, P<0.05), while there was no significant trends seen in the probability of premature death due to diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases (AAPC=0.638%, -5.250% and -2.022%, all P>0.05). The average probability of premature death due to the four diseases decreased by 4.00% each year, and decreased by 6.64% in 2025 and 5.42% in 2030 as predicted, which were both lower than the target values of 7.99% and 6.99%. Conclusions The mortality and probability of premature death due to the four diseases appeared a tendency towards a decline in Xiaoshan District from 2015 to 2021, with the probability of premature death of malignant tumors decreased significantly. It is predicted that the probability of premature death of the four diseases can reach the target in 2025 and 2030.

Human-animal interaction has a long-standing tradition dating back to ancient times. With the rapid advancements in intelligent chips, wearable devices, and machine algorithms, the intelligent interaction between animals and electronic technology, facilitated by electronic devices and systems for communication, perception, and control, has become a reality. These electronic devices aim to implement an animal-centric working mode to enhance human understanding of animals and promote the development of animal intelligence and creativity. This article takes medium-sized and large animals as research objects, with the goal of developing their ability enhancement, and introduces the concept of “intelligent animal augmentation system (IAAS)”. This concept is used to describe the characteristics of such devices and provides a comprehensive overview of existing animal and computer interface solutions. In general, IAAS can be divided into implantable and non-implantable types, each composed of interface platforms, perception and interpretation, control and instruction components. Through various levels of enhancement systems and architectural patterns, intelligent interaction between humans and animals can be realized. Although existing IAAS still lack a complete independent interaction system architecture, they hold great promise and development space in the future. Not only can they be applied as substitutes for cutting-edge devices and transportation equipment, but they are also expected to achieve cross-species information interaction through intelligent interconnection. Additionally, IAAS can promote bidirectional interaction between humans and animals, playing a significant role in advancing animal ethics and ecological protection. Furthermore, the development of interaction models based on animal subjects can provide insightful research experiences for the design of human-computer interaction systems, thereby contributing to the more efficient realization of the ambitious goal of human-machine integration.

Objective To explore the correlation of nerve function and prognosis with serum uric acid(UA),homocysteine(Hcy)and low-density lipoprotein cholesterol(LDL-C)in patients with acute cerebral infarction(ACI)after alteplase intravenous thrombolysis.Methods A total of 220 ACI patients undergoing thrombolysis in Changsha First Hospital ICU between January 2020 and December 2022 were enrolled,and according to mRS score at 3 months after thrombolysis,they were divided into poor prognosis group(mRS score＞2,91 cases)and good prognosis group(mRS score ≤2,129 cases).The serum levels of UA,Hcy and LDL-C were compared between the two groups.The correlation between the three indexes and score of National Institutes of Health Stroke Scale(NIHSS),and their predictive value for poor prognosis were analyzed.Results At 1 and 3 d after thrombolysis,the serum levels of UA,Hcy and LDL-C and NIHSS score were sig-nificantly decreased in both groups,and the serum levels of UA and Hcy and NIHSS score at 3 d after thrombolysis were significantly lower than those at 1 d(P＜0.05).The poor prognosis group had obviously higher serum levels of UA,Hcy and LDL-C and NIHSS score at 1 and 3 d after thrombolysis than the good prognosis group(P＜0.05,P＜0.01).Pearson correlation analysis showed that the serum levels of UA,Hcy and LDL-C were positively correlated with NIHSS score at 1 and 3 d after thrombolysis(P＜0.01).ROC curve analysis indicated that the AUC values of UA,Hcy and LDL-C at 1 d after thrombolysis for predicting poor prognosis were 0.707(95％CI:0.639-0.776),0.800(95％CI:0.739-0.860)and 0.624(95％CI:0.550-0.698),respectively,while the values of them at 3 d after thrombolysis were 0.655(95％CI:0.583-0.726),0.730(95％CI:0.664-0.795)and 0.573(95％CI:0.497-0.649),respectively.Conclusion In ACI patients after thrombolysis,the serum levels of UA,Hcy and LDL-C are increased in those with poor prognosis,and are associated with the severity of nerve injury.The levels at 1 d after throm-bolysis have good predictive value for poor prognosis.

Objective:To investigate the mechanism of Yunshi Ganmao Heji against respiratory syncytial virus (RSV) infection based on network pharmacology and in vivo experiments. Methods:Network pharmacological prediction: Several databases including TCMSP and GeneCards were used to predict the active ingredients and targets of Yunshi Ganmao Heji in the intervention of RSV infection. Cytoscape 3.2.1 software was used to construct the traditional Chinese medicine component-disease target network diagram. The interactions between proteins were analyzed by STRING database. GO functional enrichment analysis and KEGG pathway enrichment analysis were performed using Metascape database. Molecular docking technology was used to verify the results of network pharmacology. Experimental verification of Yunshi Ganmao Heji for the intervention of RSV infection: A mouse model of RSV infection was established through intranasal infection. After the administration of Yunshi Ganmao Heji, blood routine test results, lung indexes and pathological changes in lung tissue were analyzed. Peripheral blood T cell subsets were detected by flow cytometry. The levels of TNF-α, IL-6 and IL-1β in serum were detected by ELISA. RT-PCR was used to detect the relative expression of TLR4, NF-κB and RSV-N gene at mRNA level in lung tissues.Results:A total of 41 active ingredients of Yunshi Ganmao Heji and 111 drug targets for RSV infection were obtained. Besides, 167 signaling pathways mainly including PI3K/AKT, MAPK and Toll-like receptor signaling pathways were obtained. Molecular docking results showed that the binding energies of luteotin, kaempferol and quercetin, three active ingredients of Yunshi Ganmao Heji, with RSV-G, RSV-F, PI3K, AKT1 and Bcl-2 were less than 0 kcal/mol. In vivo experiment results showed that compared with RSV group, the counts of white blood cells and lymphocytes increased and the lung index decreased in high-dose Yunshi Ganmao Heji group, with statistically significant difference ( P<0.05). HE staining showed pulmonary hyperplasia, thickened alveolar wall and inflammatory cell infiltration in interstitium in RSV group. Alveoli in ribavirin group as well as low-dose, medium-dose and high-dose Yunshi Ganmao Heji groups tended to be of uniform size, and the alveolar walls was roughly uniform in thickness. Compared with RSV group, the low-dose, medium-dose and high-dose Yunshi Ganmao Heji groups showed significantly increased numbers of CD3 +, CD4 + and CD8 + T lymphocytes, decreased CD4 + /CD8 + T cell ratio, lower levels of TNF-α, IL-6, IL-1β in serum, and reduced viral load and inhibited expression of TLR4 and NF-κB at mRNA level in lung tissues ( P<0.05). Conclusions:Yunshi Ganmao Heji can regulate RSV infection by targeting multiple targets and pathways with several active ingredients. Its main functions are to alleviate pathological injury in lung tissues and reduce inflammatory response, and the possible mechanism underlying the antiviral functions may be related to its inhibitory effect on the activation of TLR4/NF-κB pathway.
