This paper summarized Professor BU He's clinical experience in the integrative internal and external treatment of pediatric functional constipation. He believes that dysfunction of the spleen in transportation leads to impaired function of the sanjiao （三焦） and intestinal obstruction， which constitutes the core pathogenesis of pediatric functional constipation. The treatment emphasizes regulating the spleen and harmonizing the pivot， as well as unblocking the bowel and eliminating stagnation. An integrated approach combining internal and external therapies is advocated. Internally， Chinese herbal medicine， primarily Modified Sijunzi Decoction and Shaoyao Gancao Decoction （四君子汤合芍药甘草汤加减） is used to regulate the internal organs. Externally， pediatric tuina and moxibustion on qi interlocking are employed. Together， these methods fortify the spleen and facilitate transportation， restoring the smooth function of the sanjiao pivot， and ensuring intestinal patency， thereby relieving constipation.

OBJECTIVE To systematically evaluate the methodological quality of the postoperative chemotherapy guidelines/ consensuses for ovarian epithelial tumor. METHODS A search was conducted across databases including PubMed， Embase， Web of Science， CBM， VIP， Chinese Medical Journal Data， Wanfang Data， and CNKI， as well as the official websites of GIN， NICE， Medlive， AHRQ， CSCO， ASCO， and NCCN. The search period was from the establishment of the databases/websites to March 10， 2025. The quality of the included guidelines/consensus was evaluated by using the AGREE-Ⅱ tool. RESULTS A total of 16 guidelines/consensuses were included. The domain scores of AGREE-Ⅱ evaluation were as follows： scope and purpose of 85.07%， participants of 47.92%， rigor of development of 57.49%， clarity of presentation of 88.02%， applicability of 8.20%， and independence of 53.39%. Among them， 14 were recommended at grade B and 2 were recommended at grade C. The subgroup analysis by different countries/regions and different types of studies showed that the scores for participants， rigor of development， and independence of the guidelines/consensuses in China were significantly lower than foreign countries （P＜0.05）； the scores for participants and rigor of development of the guidelines were significantly higher than consensuses （P＜0.05）. The guideline/ consensus recommendation results indicated that grade B guidelines/consensus recommend platinum-based combination chemotherapy as the preferred adjuvant chemotherapy regimen for stage Ⅰ high-grade serous carcinoma patients；platinum-based combination chemotherapy±bevacizumab was recommended as the preferred adjuvant chemotherapy regimen for stage Ⅱ-Ⅳ high- grade serous carcinoma patients and for platinum-sensitive recurrent high-grade serous carcinoma patients； non-platinum single- agent chemotherapy±bevacizumab was recommended as the preferred chemotherapy regimen for platinum-resistant recurrent high- grade serous carcinoma patients. CONCLUSIONS The overall quality of postoperative chemotherapy guidelines/consensuses for ovarian epithelial tumor is not high. The methodological quality of guidelines/consensuses in China is still lagging behind that of foreign countries. The recommendations differ from those in foreign countries. It is recommended to improve the aspects of participants， rigor of development， and independence， to recommend treatment plans based on the different stages of ovarian cancer， and develop guidelines/consensuses that align with China’s national conditions.

ObjectiveTo investigate the status and dietary intake risk of pesticide residues in fruits and vegetables sold in Wenzhou, Zhejiang Province from 2020 to 2023, so as to provide a scientific basis for the regulation and management of pesticide in the future. MethodsIn accordance with the requirements and methods specified in the “National Food Contamination and Hazardous Factor Risk Monitoring Work Manual” and the current corresponding national food inspection standards for various foods, a total of 807 samples of vegetables and fruits from various counties and districts of Wenzhou City were collected for testing and analysis. Eventually, 23 types of pesticides with a detection rate greater than 5% and those exceeding the standard were selected for dietary intake risk assessment. ResultsFrom 2020 to 2023, the overall detection rate of pesticide residues in fruits and vegetables monitored in Wenzhou was 71.62%, with an overall exceedance rate of 5.27%. From the results of the monitoring of pesticide residues in fruits and vegetables, fresh legume vegetables had the highest detection rate of 90.00%. Among the six major categories of pesticides monitored, fungicides in vegetables and fruits had the highest detection rates of 68.18% and 85.03%, respectively. The highest exceedance rate in vegetables was organophosphorus pesticides, accounting for 2.85%, while in fruits, neonicotinoid pesticides had the highest exceedance rate of 3.21%. From the perspective of sampling time, the peak detection rate of pesticide residues in fruits and vegetables in Wenzhou occurred in June and October. The index of food safety (IFS) of the 23 pesticides with a detection rate higher than 5% ranged from 0.000 7 to 0.694 2 based on the 95% monitoring value of pesticide residues, which were all less than 1. Calculated at maximum content, the IFS values of dithiocarbamate (calculated by CS₂), chlorothalonil and propiconazole were all greater than 1, indicating that the maximum detection values of the three pesticides exceeded the acceptable safety risk. The risk level of acute dietary intake of the 23 pesticides ranged from 1.26% to 52.65%. ConclusionThe overall situation of pesticide residues in fruits and vegetables sold in Wenzhou from 2020 to 2023 is favourable, but the exceedance rate of pesticide in some fruits and vegetables is high. Special attention should be paid to the pesticide residues of fungicides, neonicotinoid insecticides and organophosphorus pesticides in fresh legume vegetables, bulb vegetables and some fruits sold in Wenzhou, such as acetamiprid in bayberry and cowpea, dimethomorph in strawberry, chlorpyrifos in leek, etc., and monitoring of pesticide residues in food need to be strengthened.

Objective To investigate the role and biological mechanism of exosomal miRNA-141-3p in inducing the proliferation and invasion of prostate cancer(PCa)cells.Methods The expression level of miR-NA-141-3p in tumor tissues and adjacent tissues from 33 PCa patients,as well as in exosomes of human PCa cells VCap and normal prostate cells RWPE-2,was analyzed using quantitative real-time PCR(qPCR).The di-rect target of miRNA-141-3p was predicted through bioinformatic analysis and verified using a dual-luciferase reporter gene assay.miRNA-141-3p inhibitor plasmid(miRNA-141-3p inhibitor group)and negative control plasmid(negative control group)were transfected into human PCa cells VCap via lipofection.Cell prolifera-tion,migration,and invasion abilities in the miRNA-141-3p inhibitor group and negative control group were detected using MTT assay,wound healing assay,and Transwell assay,respectively.The mRNA expression levels of PHLPP2,E-Cadherin,and Vimentin were measured by qPCR,and the protein expression levels by Western blot,in VCap and RWPE-2 cells as well as in the miRNA-141-3p inhibitor group and negative control group.Results The expression level of exosomal miRNA-141-3p in tumor tissues was significantly higher than in adjacent tissues(P<0.05).Dual-luciferase reporter assay confirmed that PHLPP2 is the direct target gene of miRNA-141-3p.The expression levels of exosomal PHLPP2,E-Cadherin mRNA and protein in VCap cells were lower than in RWPE-2 cells,while the expression levels of Vimentin mRNA and protein were high-er than in RWPE-2 cells,with statistically significant intergroup differences(P=0.012).In the miR-141-3p inhibitor group,exosomal miR-141-3p,Vimentin mRNA expression level,cell proliferation rate(MTS assay),migrating cell count(scratch assay),and transmembrane cell count(Transwell invasion assay)were signifi-cantly decreased compared to the negative control group,while PHLPP2 mRNA and E-Cadherin mRNA ex-pression levels were significantly increased,with statistically significant intergroup differences(P<0.05).Conclusion miR-141-3p promotes proliferation and migration of human PCa cells by targeting PHLPP2.

Objective:To observe the efficacy and safety of combined lienal polypeptide injection therapy in the treatment of Mycoplasma pneumoniae pneumonia（MPP）in children aged 3 to 14 years old in multiple clinical centers.Methods:A randomized，controlled，multi-center clinical study design was adopted.A total of 240 hospitalized children aged 3 to 14 years old with MPP from 7 hospitals from September 1，2023 to January 31，2024 were included.According to the severity of pneumonia，they were divided into the mild MPP group with 80 cases and the severe MPP/refractory MPP（SMPP/RMPP）group with 160 cases，and then randomly divided into the control group and the experimental group at a ratio of 1 ∶1，using the random number table method.After screening，subjects entered a treatment period of 5 to 7 days.The control group was treated with azithromycin，while the experimental group was treated with azithromycin plus lienal polypeptide injection .The recovery of lung CT，length of hospital stay，duration of fever，cough score，whether mild cases developed into severe or refractory cases，duration of hormone use，use of intravenous immunoglobulin（IVIG），bronchoscopy treatment，and immune function were observed between the two groups to evaluate the efficacy of lienal polypeptide injection.Adverse events after medication，vital signs，blood routine，urine routine，liver function，myocardial enzymes，renal function，and electrocardiogram were observed to evaluate the safety. Results:A total of 231 subjects have completed the trial in the 7 hospitals，including 118 cases in the experimental group and 113 cases in the control group.Main observation index：the rate of lung CT aggravation in the experimental group was lower than that in the control group（2.6% vs 15.3%， P<0.01），and the difference was statistically significant.Secondary indexes：there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.However，the rate of cases of plastic bronchitis（PB）found under bronchoscopy in the experimental group was lower than that in the control group（0 vs 18.8%， P=0.03），and the difference was statistically significant.Among the mild MPP（72 cases），there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and the improvement rate of lung CT between the two groups（all P>0.05）.However，compared with the control group，the rate of cases developing into SMPP/RMPP in the experimental group was less（24.3% vs 48.6%， P=0.03），and the difference in IgG before and after treatment was small［0.53（-0.04，1.18）g/L vs 1.33（0.48，2.25）g/L， P=0.01］.Among the SMPP/RMPP cases（159 cases），the rate of cases of PB found under bronchoscopy in the experimental group was less than that in the control group（0 vs 20%， P=0.04），and the rate of cases with aggravated lung CT in the experimental group was less than that in the control group（1.3% vs 19.5%， P<0.01），and the improvement rate of lung CT in the experimental group was higher than that in the control group（88.8% vs 75.3%， P=0.03），with statistically significant differences.There were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.Two cases in the experimental group developed rashes，which improved after the drug was discontinued.There were no serious adverse reactions such as abnormal vital signs like dyspnea and cyanosis due to the use of lienal polypeptide injection.There were no obvious changes in blood routine，liver function，myocardial enzymes，renal function，electrocardiogram，and urine routine values before and after medication compared with the baseline. Conclusion:The combined use of lienal polypeptide injection in the treatment of MPP in children can reduce the probability of the transformation from mild cases to SMPP/RMPP，reduce the rate of aggravation of the image findings，promote the absorption of lung inflammation，reduce the rate of PB found under bronchoscopy，and has good safety.

Objective To explore the effect of Sangxing Zhike Formula in rats with cough vari-ant asthma(CVA)and its possible mechanism based on the cyclic adenosine monophosphate(cAMP)/cystic fibrosis transmembrane conductance regulator(CFTR)pathway.Methods SD rats were randomly divided into control group,model group,dexamethasone group(0.5 mg/kg)and low-,medium-,high-dose Sangxing Zhike Formula groups(9.6,19.2 and 38.4 g/kg)using a ran-dom number table method,with 9 rats in each group.Except for the control group,CVA rat models were established in the other groups.Rats in each group were administered the drug by gavage once a day for 14 consecutive days.The general conditions of rats in each group were observed.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of interleukin-1β(IL-1β)and interleukin-18(IL-18)in rat serum.Hematoxylin-eosin(HE)staining and periodic acid-Schiff(PAS)staining were used to observe the pathological changes in rat lung and bronchial tissues,and the acid-base balance of airway surface liquid(ASL)was measured.Western blot and real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)were used to detect the expression levels of pro-tein kinase A(PKA),CFTR protein and their mRNA in lung tissues of rats.Results Compared with the control group,rats in the model group showed listlessness,dull fur,slow weight gain,a significantly expanded area of alveolar septal consolidation,and a large number of inflammatory cell infiltrations around the bronchi.Compared with the model group,rats in each intervention group had better general conditions and reduced inflammatory infiltrations in lung tissues and bronchial lu-mens.Compared with the control group,the serum levels of IL-1 β and IL-18 in the model group were increased,and the pH values of ASL in the model group,low-dose Sangxing Zhike Formula group,medium-dose Sangxing Zhike Formula group,and high-dose Sangxing Zhike Formula group were all decreased,with statistically significant differences(P＜0.05).Compared with the model group,the serum levels of IL-1β and IL-18 in each intervention group were decreased,and the pH values of ASL in the dexamethasone group,medium-dose Sangxing Zhike Formula group,and high-dose Sangxing Zhike Formula group were increased,with statistically significant differences(P＜0.05).Compared with the control group,the expressions of PKA protein and PKA mRNA in the model group,low-dose Sangxing Zhike Formula group,and medium-dose Sangxing Zhike Formula group were all decreased,and the expressions of CFTR protein and CFTR mRNA in the model group and each intervention group were all decreased,with statistically significant differences(P＜0.05).Compared with the model group,the expressions of PKA protein and PKA mRNA in the dexametha-sone group and high-dose Sangxing Zhike Formula group were increased,and the expressions of CFTR protein and CFTR mRNA in the high-dose Sangxing Zhike Formula group were increased,with statistically significant differences(P＜0.05).Conclusion Sangxing Zhike Formula can im-prove the general conditions of CVA rats,regulate the acid-base balance of ASL,reduce airway in-flammatory cell infiltration andairway remodeling,and decrease the levels of inflammatory factors IL-1β and IL-18.Its mechanism may be related to the cAMP/CFTR pathway.

Objective: To predict and screen potential biomarkers of systemic lupus eythematosus(SLE) based on machine learning algorithms and structural biology, and to reveal their mechanisms of action and to provide new targets for disease diagnosis and treatment. Methods: Four machine learning algorithms, random forest(RF), eXtreme gradient boosting(XGBoost), support vector machine(SVM), least absolute shrinkage and selection operator(LASSO), were used to analyze the gene expression data of SLE patients in GEO(datasets: GSE121239 and GSE11907) to analyze the gene expression data of SLE patients and screen key markers. Peripheral blood single nucleated cells(PBMCs) from SLE patients were collected and RT-qPCR was used to detect differential gene expression levels. Subsequently, GSEA enrichment analysis was used to identify biomarker-related pathways. CIBERSORT immune infiltration analysis and protein interactions network were applied to calculate the sample immune cell infiltration abundance. Single-cell data were analyzed for gene expression specificity in immune cells. Interaction relationships in combination with AlphaFold3(AF3) were predicted. Results: Multiple algorithms were screened together to identify the unique marker gene HERC5 , and expression analysis of multiple datasets showed that HERC5 was highly expressed in SLE compared to the normal group (P < 0. 05) , and RT⁃qPCR verified the same trend (P = 0. 006 2) . Functional enrichment analysis identified the major pathway promoted by HERC5 in SLE as the interferon receptor signalling pathway (P < 0. 05) . Immune infiltration analysis showed that HERC5 was closely associated with immune cells (Neutrophils : r = 0. 39 , P < 0. 05 ; Memory B cells : r = 0. 33 , P < 0. 05 ; Activated dendritic cell : r = 0. 52 , P < 0. 05) . Most HERC5 ⁃related interacting proteins were associated with SLE ,and potential transcription factors of HERC5 and its related genes were also significantly associated with immune responses. Conclusion The HERC5 gene is an important biomarker for SLE , which upregulates the interferon pathway to promote SLE progression and provides a new target for SLE diagnosis and treatment.

Ribosome is an intracellular ribonucleoprotein particle that serves as the site of protein biosynthesis. Ribosomal dysfunction caused by mutations in genes encoding ribosomal proteins (RPs) and ribosome biogenesis factors (RBFs) can lead to a spectrum of diseases, collectively known as ribosomopathy. Phase separation is a thermodynamic process that produces multiple phases from a homogeneous mixture. The formation of membraneless organelles and intracellular structures, including ribosomes and nucleoli, cannot occur without the involvement of phase separation. Here, ribosome structure, biogenesis, and their relationship with ribosomopathy are systematically reviewed. The tissue specificity of ribosomopathy and the role of phase separation in ribosomopathy are particularly discussed, which may offer some clues for understanding the mechanisms of ribosomopathy. Then, some new ideas for the prevention, diagnosis, and treatment of ribosomopathy are provided.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.
