Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

Objective:
To explore the correlation and lag effects of environmental factors on pediatric respiratory disease visits at hospital, so as to provide scientific basis for disease prediction and optimizing clinical diagnosis and treatment.
Methods:
Data from 503 889 pediatric respiratory disease outpatient and emergency visits a central hospital in Minhang District of Shanghai between 2017 and 2019, along with concurrent meteorological data were collected. A distributed lag non-linear models (DLNM) was constructed to explore the specific relationship between pediatric respiratory disease consultations and various environmental factors and to quantify the cumulative lag effects of environmental factors on respiratory disease consultations.
Results:
Among the environmental factors, temperature, fine particulate matter (PM 2.5 ), inhalable particulate matter (PM 10 ), nitrogen dioxide (NO 2), and sulfur dioxide (SO 2) were associated with pediatric respiratory disease visits. After adjusting for temperature, PM 2.5 and PM 10 concentrations did not show significant immediate or lag effects. The relative risk (RR) of pediatric respiratory disease visits increased with rising NO 2 concentrations. When NO 2 concentration ≥55 μg/m 3, significant immediate and lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.05, 1.13, 1.17, and 1.21( P <0.05). The RR values showed an inverted “U” shaped relationship with SO 2 concentrations. When SO 2 concentration ≥5 μg/m 3, significant lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.03 , 1.03, and 1.04 ( P <0.05).
Conclusion
High concentrations of NO 2 and SO 2 increase the risk of pediatric respiratory disease visits, with observable lag effects.

ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ2=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ2=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

Objective: To investigate the effects of different storage temperatures and durations on the activities of coagulation factor Ⅷ (Factor Ⅷ, FⅧ) and coagulation factor Ⅸ (Factor Ⅸ, FⅨ) after whole blood collection, so as to provide data support for the optimal storage conditions. Methods: A total of 16 mL of whole blood was collected from each of the 20 healthy volunteers at our blood center and aliquoted into 8 sodium citrate anticoagulant tubes. Two tubes were immediately centrifuged for the measurement of FⅧ and FⅨ activity levels. The remaining 6 tubes of whole blood were respectively stored under room temperature and low-temperature conditions. At 2, 4, and 6 h, the whole blood samples were centrifuged and analyzed for FⅧ and FⅨ activity levels. The mean values of the two immediately tested tubes were used as the control group, while other tubes were designated as the experimental groups for comparison. Statistical analysis was performed using SPSS 26.0. Results: The activity of FⅧ in whole blood remained stable after 4 hours of storage at both room temperature and low temperature (116.53±25.95 vs 125.22±27.33, 109.77±23.23 vs 125.22±27.33) (P>0.05 for both). However, by 6 hours, FⅧ activity showed a statistically significant decline compared to the control group (108.65±22.92 vs 125.22±27.33, 100.46±20.19 vs 125.22±27.33) (P<0.05 for both), though the room temperature group results were closer to the control values. The activity of FⅨ in whole blood remained stable after 6 hours of storage under both conditions (97.14±19.48 vs 96.76±19.67, 97.10±17.45 vs 96.76±19.6) (P>0.05 for all comparisons). Conclusion: For whole blood samples after collection, storage at either room temperature or low temperature for up to 4 hours does not compromise the accuracy of test results. When stored for 6 hours, FⅨ activity remains stable, whereas FⅧ activity decreases significantly. Notably, FⅧ activity demonstrates better stability at room temperature than under low-temperature conditions within the 6-hour storage.

Chronic heart failure (CHF) is the terminal stage of various heart diseases, with high morbidity, mortality, and hospitalization rate. According to the theory of collateral diseases, the core pathogenesis of CHF is blood stasis of collaterals, water retention and stagnation, and pathogen accumulation in collaterals. Accordingly, the treatment should focus on reinforcing healthy Qi to warm Yang, activating blood to dredge collaterals, and excreting water to alleviate edema. On this basis, Qili Qiangxin capsules (QLQX) are created. This prescription can effectively treat chronic heart failure. Modern studies have shown that QLQX contains a variety of pharmacological components such as flavonoids, alkaloids, terpenoids, phenylpropanoids, phenolic acids, and cardiac glycosides. QLQX can improve the cardiac function, inhibit myocardial fibrosis, improve hemodynamics, mitigate inflammation, reduce cardiomyocyte apoptosis, and regulate the nervous system, with mild adverse reactions. This study analyzed the etiology and pathogenesis of CHF based on the theory of collateral diseases, explored the relationship between the prescription and syndrome, and delved into the material basis and mechanism of QLQX in the treatment of CHF, aiming to provide reference for the clinical application and scientific research of QLQX.

ObjectiveTo investigate the effects and mechanism of the combination of arsenic trioxide (ATO) and its dimethylarsinic acid (DMAV) metabolite on apoptosis of human acute promyelocytic leukemia NB4 cells by affecting the balance of metabolic reaction. MethodsThe rats were injected with the same amount of sterile normal saline, ATO(1.6 mg·kg-1), and DMAV(4, 8, 16, and 32 mg·kg-1) combined with ATO(1.6 mg·kg-1), respectively, to obtain the corresponding drug-containing serum. The effect of drug-containing serum on the proliferation of NB4 cells was detected by the cell counting kit-8 (CCK-8 )method. Apoptosis was detected by flow cytometry with Annexin-V-FITC/PI double staining. Intracellular reactive oxygen species (ROS) accumulation was detected by flow cytometry using fluorescent probe DCFH-DA. The changes of mitochondrial membrane potential (Δψm) were detected by the fluorescence probe JC-1. Western blot detected the expression of apoptosis-related proteins, namely B-cell lymphoma-2(Bcl-2)-associated X protein(Bax)/Bcl-2, Cytochrome C, cleaved Caspase-9, and cleaved Caspase-3, as well as c-Jun N-terminal kinase(JNK) phosphorylation levels. Results①The Combination of the two drugs had a higher proliferation inhibition rate and more apoptosis than ATO alone. ②The combination of two drugs can significantly increase the production of ROS compared with any single treatment group. ③The Δψm was significantly reduced in the two-drug combination group compared with any single treatment group. ④Compared with either group, the combination group significantly released Cytochrome C, significantly down-regulated the expression of Bcl-2, and up-regulated the expression of Bax, cleaved Caspase-3, and cleaved Caspase-9. ⑤The phosphorylation level of JNK was significantly up-regulated in the two-drug combination group compared with any single treatment group. ConclusionThe combination of DMAV and ATO may synergistically induce mitochondrial apoptosis through ROS-mediated oxidative stress, triggering Δψm dissipation and Cytochrome C release. By activating Caspase-9/Caspase-3 and the phosphorylation level of JNK, the Bcl-2 family protein (Bax/Bcl-2) was regulated to promote the apoptosis of NB4 cells.

On-site supervision is a risk-based regulatory system that requires the scientific development of supervision plans for quality risks and hidden dangers in pharmaceutical enterprises, the rational allocation of supervision resources based on their risk levels, and the implementation of classified supervision measures. In this study, the quality risk monitoring business support system is set up for pharmaceutical enterprises by establishing the quality risk expert database and quality risk monitoring index system for pharmaceutical enterprises based on the difficulty analysis of on-site drug supervision. Based on this support system, the quality risk classification method, the differentiated spot check strategy and business auxiliary visualization system are established. This support system is used to learn the risk level of pharmaceutical enterprises, so as to innovate supervision methods and optimize monitoring strategies. Taking Jiangxi Province as an example, it is verified that the support system can guide the risk assessment of sample enterprises, can improve the targeting of on-site drug supervision in the process of technical review, scheme editing, on-site implementation and comprehensive evaluation, and can effectively improve the quality and efficiency of supervision.

Objective To discuss the perioperative care and wound protection of xenotransplantation from genetically edited pigs to monkeys, with the goal of improving the success rate of such experimental procedures. Methods From October 2022 to October 2023, perioperative care and wound protection were performed on 7 recipient rhesus monkeys undergoing xenotransplantation of genetically edited pig tissues and organs. Customized wound protective garments were designed based on monkeys' size and surgical area to protect the wounds, alongside meticulous perioperative care. This included preoperative preparation and medication, intraoperative monitoring of physiological indicators and anesthesia management, and postoperative care comprising wound protection, observation and monitoring, and nutritional support. Results All seven monkeys successfully underwent xenotransplantation. With the aid of protective garments and detailed care, all surgical wounds healed by first intention, and postoperative recovery was satisfactory. Conclusion Proper care and wound protection during xenotransplantation from genetically edited pigs to monkeys not only promote wound healing, but also alleviate pain and harm to animals. This has significant implications for advancing experimental research in pig-monkey xenotransplantation and enhancing animal welfare.

As a kind of immunosuppressive cells, myeloid-derived suppressor cells (MDSCs) are an important component of the immune microenvironment. MDSCs play a significant role in promoting tumor immune escape. In addition, non-immunological functions such as promoting angiogenesis can also promote tumor development with the deepening of research. MDSCs can promote tumor angiogenesis directly through vascular endothelial growth factor signaling pathway, or promote tumor growth and angiogenesis by secreting cytokines such as matrix metalloprotein-9, basic fibroblast growth factor, angiogenic peptide Bv8, platelet derived growth factor, exosomes, or interacting with other cells. Exploring the expansion, activation, recruitment and angiogenesis mechanism of MDSCs will provide new ideas for regulating the individualized diagnosis and treatment based on targeted MDSCs.

Objective:To evaluate the therapeutic effect of glycyrrhetinic acid on cough variant asthma (CVA) mice based on molecular docking technique; To explore the possibility of its treatment for cough variant asthma.Methods:The software of Autodock Vina was used for molecular docking. The mice were divided into control group, model group, prednisone acetate group, glycyrrhetinic acid high-, medium-, and low-dosage groups according to the random number table method, with 8 mice in each group. Except for the blank control group, all other groups were induced by egg protein to establish cough variant asthma models. Glycyrrhetinic acid high-, medium-, and low-dosage groups were orally administered glycyrrhetinic acid suspension at 20, 10, and 5 mg/kg, while the prednisone acetate group was orally administered prednisone acetate at 5 mg/kg. The blank control group and model group were orally administered equal volumes of physiological saline, once per day for 14 consecutive days. The animal asthma behavior was observed after drug administration. The secretion of bronchial mucus in lung tissue were observed by AB-PAS staining and the index of spleen were recorded. The protein expressions of Gata3, IL-4 and IL-13 in the spleen tissue were determined by Western blot.Results:Molecular docking results showed that glycyrrhetinic acid had good binding ability to Th2-related factors Gata3, IL-4 and IL-13. Results of animal experiment showed that compared with the model group, the mucus secretion decreased in glycyrrhetinic acid groups, the index of the spleen of mice obviously decreased, protein expression levels of IL-4 and IL-13 in the spleen tissue of mice in glycyrrhetinic acid high-, medium-, and low-dosage groups decreased ( P<0.05), and Gata3 in glycyrrhetinic acid medium- and low-dosage groups decreased ( P<0.05). Conclusion:Glycyrrhetinic acid can correct the shift of Th2 in the immune system of cough variant asthma mice and has a certain therapeutic effect.
