Objective:
To analyze the relationship between 24 h movement behaviors and cognitive function in children and adolescents, as well as the isotemporal substitution benefits, in order to provide a basis for developing cognitive development intervention strategies among children and adolescents.
Methods:
Relevant studies were searched in the Web of Science, PubMed, Embase, EBSCO, and China National Knowledge Infrastructure databases from their inception to November 30, 2024. Systematic evaluation was performed after document screening, data extraction and quality assessment.
Results:
A total of 24 highquality studies were included, comprising 35 295 children and adolescents aged 3-18 years. Adhering to the 24 h activity guidelines was associated with better cognitive performance (19 studies). Additionally, substituting 5-30 minutes per day of moderate to vigorous physical activity (MVPA) or sleep (SLP) for sedentary behavior (SB) or light physical activity (LPA) were associated with improvements in cognitive function (7 studies). There were inconsistencies in the effects of different types of SB (learning or entertainment) on cognitive function.
Conclusions
Adherence to the 24 h activity guidelines supports cognitive development in children and adolescents, with MVPA and SLP as key intervention targets. Increasing the proportion of MVPA, ensuring adequate SLP, and limiting recreational SB and screen time might be helpful to enhance the combined benefits of these three behaviors.

ObjectiveTo assess the availability of bronchodilators for treatment of chronic obstructive pulmonary disease (COPD) in community health service centers (CHCs) in Shanghai. MethodsOn the basis of previous research, the questionnaire was updated, and surveys were conducted from April to May 2023 in CHCs in Shanghai, with a focus on the availability of medications for COPD treatment. According to the National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance Drug List (2023 Edition), a total of 24 types of bronchodilators for COPD treatment were identified. The availability rates were used to assess the accessibility of specific drugs in CHCs, and the dispensing rates were used to evaluate the variety of these medications in CHCs. ResultsA total of 248 CHCs responded, with a response rate of 100.0%. Among them, a total of 232 CHCs (93.5%) were equipped with bronchodilators. In terms of availability rates, the availability rates for β2 adrenoreceptor agonists, muscarinic antagonists, combination drugs, and xanthines drugs were 86.3%, 52.0%, 52.4%, and 85.1%, respectively. Regional differences were observed, in that salbutamol/levalbuterol and budesonide-formoterol were less available in suburban CHCs, ipratropium bromide had lower availability in urban CHCs, and aminophylline was more available in suburban CHCs. Regarding the dispensing rates of the 24 types of bronchodilators for COPD treatment, the median of types equipped by CHCs was 5, with a total of 200 CHCs (80.6%) equipped with fewer than 7 types of bronchodilator drugs. ConclusionThe proportion of CHCs in Shanghai equipped with bronchodilators for COPD is relatively high. However, there exist problems such as limited variety of stocked medications, significant differences in the availability of different drugs, and regional imbalances in drug stocking. To improve the standardized diagnosis, treatment, and management of COPD patients, it is recommended to enhance the availability of COPD treatment medications in CHCs.

ObjectiveTo investigate the content of trihalomethanes (THMs) in treated water after different water treatment processes and their correlations with premanganate index, so as to provide data support for the renovation of water production process and optimization of water quality improvement. MethodsFrom 2022 to 2023, seven centralized water supply units using raw water from Qingcaosha reservoir were selected as the testing sites, among which three units with the conventional treatment process, two units with the advanced treatment process, and two units with the advanced treatment process combined CO2 treatment. Monthly water quality testing data were collected, focusing on testing the concentration variations of THMs, trichloromethane, dibromochloromethane, bromodichloromethane, bromoform, and permanganate index. ResultsThe comparison between conventional treatment process and advanced treatment process demonstrated that the conventional treatment process exhibited significantly higher concentrations of trihalomethanes, trichloromethane, bromodichloromethane, and permanganate index in water samples (all P<0.05). When comparing conventional treatment process with advanced treatment process combined with carbon dioxide treatment, the conventional treatment process showed significantly elevated levels of trihalomethanes, dibromochloromethane, bromodichloromethane, and permanganate index (all P<0.05). No statistically significant differences were observed in the comparison of various indicators between advanced treatment process and advanced treatment process combined with carbon dioxide treatment for any of the measured parameters (all P>0.05). Analysis of seasonal variations revealed that finished water during the high-temperature period (May to November) contained significantly higher concentrations of trihalomethanes, trichloromethane, bromodichloromethane, and tribromomethane compared to the low-temperature period (December to April of the following year) (all P<0.05). Significant positive correlations were identified between permanganate index and trihalomethanes (r=0.213, P=0.007), permanganate index and dibromochloromethane (r=0.186, P=0.019), permanganate index and bromodichloromethane (r=0.243, P=0.002), permanganate index and tribromomethane (r=0.193, P=0.014). ConclusionCompared to the conventional water treatment process, advanced treatment process and advanced treatment combined with CO2 injection process can significantly reduce the concentrations of THMs in the treated effluent water. Besides, the generation of THMs is affected by seasonal temperatures, with higher concentrations of THMs, trichloromethane, bromodichloromethane, and bromoform being observed in the high-temperature season. Additionally, the permanganate index shows a significant positive correlation with THMs concentrations, indicating that the content of organic matter in the source of raw water contributes to the generation of THMs in the treated water.

OBJECTIVE:
To explore the effect of bear bile powder (BBP) on acute lung injury (ALI) and the underlying mechanism.
METHODS:
The chemical constituents of BBP were analyzed by ultra-high-pressure liquid chromatography-mass spectrometry (UPLC-MS). After 7 days of adaptive feeding, 50 mice were randomly divided into 5 groups by a random number table (n=10): normal control (NC), lipopolysaccharide (LPS), dexamethasone (Dex), low-, and high-dose BBP groups. The dosing cycle was 9 days. On the 12th and 14th days, 20 µL of Staphylococcus aureus solution (bacterial concentration of 1 × 10-7 CFU/mL) was given by nasal drip after 1 h of intragastric administration, and the mice in the NC group was given the same dose of phosphated buffered saline (PBS) solution. On the 16th day, after 1 h intragastric administration, 100 µL of LPS solution (1 mg/mL) was given by tracheal intubation, and the same dose of PBS solution was given to the NC group. Lung tissue was obtained to measure the myeloperoxidase (MPO) activity, the lung wet/dry weight ratio and expressions of CD14 and other related proteins. The lower lobe of the right lung was obtained for pathological examination. The concentrations of inflammatory cytokines including interleukin (IL)-6, tumour necrosis factor α (TNF-α ) and IL-1β in the bronchoalveolar lavage fluid (BALF) were detected by enzyme linked immunosorbent assay, and the number of neutrophils was counted. The colonic contents of the mice were analyzed by 16 sRNA technique and the contents of short-chain fatty acids (SCFAs) were measured by gas chromatograph-mass spectrometer (GC-MS).
RESULTS:
UPLC-MS revealed that the chemical components of BBP samples were mainly tauroursodeoxycholic acid and taurochenodeoxycholic acid sodium salt. BBP reduced the activity of MPO, concentrations of inflammatory cytokines, and inhibited the expression of CD14 protein, thus suppressing the activation of NF-κB pathway (P<0.05). The lung histopathological results indicated that BBP significantly reduced the degree of neutrophil infiltration, cell shedding, necrosis, and alveolar cavity depression. Moreover, BBP effectively regulated the composition of the intestinal microflora and increased the production of SCFAs, which contributed to its treatment effect (P<0.05).
CONCLUSIONS
BBP alleviates lung injury in ALI mouse through inhibiting activation of NF-κB pathway and decreasing expression of CD14 protein. BBP may promote recovery of ALI by improving the structure of intestinal flora and enhancing metabolic function of intestinal flora.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To investigate the efficacy and safety of exchange transfusion in neonates with severe pertussis. Methods A retrospective analysis was performed for the medical data of five neonates with severe pertussis who underwent exchange transfusion in the Department of Neonatology,Hunan Children's Hospital,from August 2019 to March 2024. The clinical characteristics of the patients were summarized,and the efficacy and adverse reactions of exchange transfusion were analyzed. Results All five neonates had the symptoms of hypoxemia,recurrent apnea,and heart failure and required invasive mechanical ventilation. Two cases of pulmonary hypertension were observed,one of which was complicated by decompensated shock. Before exchange transfusion,the five children had a median leukocyte count of 82.60×109/L,a median absolute lymphocyte count of 28.20×109/L,and a median absolute neutrophil count of 43.10×109/L,and reexamination at 4 hours after exchange transfusion showed that these values decreased to 28.40×109/L,7.60×109/L,and 15.40×109/L,respectively. The four children who underwent exchange transfusion in the early stage of cardiopulmonary failure showed varying degrees of improvement in oxygenation and a reduction in the partial pressure of carbon dioxide,and they were discharged after improvement;the one child who underwent exchange transfusion in the late stage of cardiopulmonary failure ultimately died. No child experienced severe adverse reactions related to exchange transfusion. Conclusions For neonates with severe pertussis,initiating exchange transfusion in the early stages of cardiopulmonary failure can effectively reduce leukocyte levels,potentially improve survival rates,and is relatively safe.
