OBJECTIVE To analyze the clinical characteristics and influential factors of drug-induced liver injury （DILI） in children caused by intravenous azithromycin. METHODS Clinical data of 157 DILI pediatric cases caused by intravenous azithromycin， reported by the Hengshui Adverse Drug Reaction Monitoring Center from January 2015 to January 2025， were collected as the observation group. Clinical data of pediatric patients who received intravenous azithromycin but did not develop DILI during the same period at Hengshui People’s Hospital were collected in a 1∶1 ratio to serve as the control group. The clinical classification， severity and prognosis of DILI in pediatric patients from the observation group were analyzed. Univariate and multivariate Logistic regression analyses were used to screen the independent risk factors for DILI in children caused by intravenous azithromycin. RESULTS Among 157 DILI cases， 92 cases （58.60%） had hepatocellular injury-type， 51 cases （32.48%） had cholestatic-type， and 14 cases （8.92%） had mixed-type. DILI severity was grade 1 in 117 cases （74.52%）， grade 2 in 33 cases （21.02%）， and grade 3 in 7 cases （4.46%）. Liver function had all recovered after stopping medication and symptomatic treatment. Combined with acetaminophen [OR＝3.769， 95%CI （1.615， 8.235）， P＝0.021]， daily dose of azithromycin＞10 mg/kg [OR＝ 2.237， 95%CI （1.075， 4.655）， P＝0.034] were independent risk factors for DILI in children caused by intravenous azithromycin. CONCLUSIONS Hepatocellular injury-type and cholestatic-type are relatively common in children with DILI caused by intravenous azithromycin， with mild severity being predominant and showing a favorable prognosis. Combination with acetaminophen and daily dose＞10 mg/kg are independent risk factors for azithromycin-induced DILI in children.

OBJECTIVE To evaluate the efficacy and safety of first-line treatments regimens for human epidermal growth factor receptor 2 （HER2）-positive advanced gastric cancer. METHODS Computer searches were conducted on databases such as Web of Science， Embase， CNKI， and VIP in both Chinese and English， and abstracts of papers from the annual meetings of the European Society of Oncology and the American Society of Clinical Oncology were screened. Collected randomized controlled trials （RCTs） on first-line treatment for HER2-positive advanced unresectable or metastatic gastric cancer or gastroesophageal junction adenocarcinoma patients， with a retrieval period from database establishment until April 1， 2025. A network meta-analysis was conducted by two researchers who independently screened literature， extracted data， and evaluated the risk of bias in the study. RESULTS A total of 5 RCTs involving 2 797 patients and encompassing 6 treatment regimens were ultimately included. In the assessment of overall survival， there was a trend towards survival benefit for trastuzumab combined with chemotherapy （Tra_chemo）， pertuzumab combined with trastuzumab and chemotherapy （Per_Tra_chemo）， high-dose trastuzumab combined with chemotherapy （TraHD_chemo）， lapatinib combined with chemotherapy （Lap_chemo）， and pembrolizumab combined with trastuzumab and chemotherapy （Pem_Tra_chemo） compared to chemotherapy alone （chemo）； however， the differences were not statistically significant （P＞0.05）； the top two treatment regimens in terms of the surface under the cumulative ranking curve （SUCRA） were Pem_Tra_chemo （77.8%） and TraHD_chemo （74.2%）. For progression-free survival， there was statistical significance between Per_Tra_chemo and chemo， Pem_Tra_chemo and chemo （P＜0.05）； the top two treatment regimens in terms of SUCRA were Per_Tra_chemo （83.0%） and Pem_Tra_chemo （82.8%）. Regarding objective response rate， there was statistical significance between Pem_Tra_chemo and chemo （P＜0.05）； the top two treatment regimens in terms of SUCRA were Pem_Tra_chemo（87.4%）and Per_Tra_chemo（72.2%）. In terms of safety， there was statistical significance in the incidence of any level of adverse events between Lap_chemo and chemo （P＜0.05）； the top two treatment regimens in terms of SUCRA were chemo（87.1%）and Pem_Tra_chemo（53.8%）. Lap_chemo exhibited a higher incidence of grade ≥3 adverse events compared to chemo， and Per_Tra_chemo showed a higher incidence compared to Tra_chemo （P＜0.05）； the top two treatment regimens in terms of SUCRA were Tra_chemo （79.0%） and chemo （77.6%）. CONCLUSIONS In the first-line treatment of HER2-positive advanced gastric cancer， Pem_Tra_chemo and Per_Tra_chemo regimens have relatively good efficacy， but the safety risks are relatively high， requiring close attention and whole- process management.

ObjectiveTo investigate the effect of Yunkang oral liquid on postpartum kidney deficiency in mice. MethodPostpartum mice were randomized into model and low-dose （6 mL·kg^-1）， medium-dose （9 mL·kg^-1）， and high-dose （12 mL·kg^-1） Yunkang oral liquid groups. The mouse model of postpartum kidney deficiency was established by sleep deprivation combined with forced swimming. Another 9 female ICR mice were selected as the normal control group. The mice were administrated with Yunkang oral liquid during the period of modeling. The levels of estradiol （E₂）， progesterone （P）， follicle-stimulating hormone （FSH）， and luteinizing hormone （LH） in the serum were measured by the enzyme-linked immunosorbent assay. The morphological changes of ovaries and uterus were observed by hematoxylin-eosin （HE） staining， and the expression of transforming growth factor （TGF）-β and Smad2/3 was determined by immunohistochemistry and Western blotting. ResultThe mice in the model group showed prolonged estrous cycle， reduced voluntary activity， dorsal temperature， grip strength， and bone strength， and whitening tongue coating. Compared with the model group， Yunkang oral liquid shortened the estrous cycle， increased the voluntary activity， dorsal temperature， grip strength， and bone strength， and alleviated the whitening of tongue coating. Moreover， it elevated the E₂ and P levels and lowered the FSH and LH levels in the serum， decreased ovarian follicular atresia rate， promoted uterine repair， and down-regulated the expression of TGF-β and Smad2/3 in the ovarian and uterine tissues. ConclusionYunkang oral liquid can ameliorate postpartum kidney deficiency in mice by regulating the TGF-β/Smads signaling pathway.

This article reported a patient who initially presented with insomnia complaints and was subsequently diagnosed with severe obstructive sleep apnea （OSA） on polysomnography （PSG）. The patient tried continuous positive airway pressure （CPAP）but gave up because wear the ventilator made it more difficult to fall asleep. Then the patient only received group cognitive behavioral therapy for insomnia （CBT-I）， which not only alleviated insomnia severity but also promoted severe OSA into mild status. Such case suggested that， firstly， due to the high comorbidity of insomnia and OSA， evaluation of OSA should be considered a part worth enough attention of the clinical diagnosis and treatment of insomnia patients. Secondly， by relieving insomnia， CBT-I can alleviate both nocturnal apnea and daytime somnolence in patients with comorbid insomnia and sleep apnoea （COMISA）， so the application of CBT-I should be emphasized in the treatment of such patients. ［Funded by the Central Government-guided Local Science and Technology Development Fund Project （number， 2022ZY0028）］

Objective To investigate the expression of histone deacetylase(HDAC)isoforms in the frontal lobe,hippo-campus and liver of offspring rats delivered by rats with maternal immune activation and their correlation with the efficiency of prepulse inhibition(PPI％).Methods Ten pregnant Sprague-Dawley rats were randomly divided into the model group(n=5)and control group(n=5).The rats in the model group were injected with 10 mg·kg-1 polyinosinic-polycytidylic acid(Poly I:C)via the caudal vein on the 9th day of pregnancy,while rats in the control group were given the same volume of sterile physiological saline.After 3 h,blood was collected from the caudal vein,and the levels of interleukin(IL)-1 β,IL-6 and tumor necrosis factor-α(TNF-α)in the plasma of pregnant rats were detected by enzyme-linked immunosorbent assay to evaluate the immune activation status.The pregnant rats in the two groups were fed until natural delivery,the offspring rats were weaned on the 21st day after birth,and the male offspring rats were fed continuously.A prepulse inhibition test was performed at puberty(the 40th day after birth)to evaluate the spatial recognition memory and sensory gating function of the offspring rats.The expression levels of the HDAC gene family in the hippocampus,frontal lobe and liver of offspring rats were detected by real-time fluorescence quantitative polymerase chain reaction.Results The plasma IL-6,IL-1 β and TNF-α levels in the model group were significantly higher than those in the control group(P＜0.05).When the prepulse stimulation was 75 dB,the PPI％of the offspring rats at puberty in the model group was significantly lower than that in the control group(P＜0.05).When the prepulse stimulation was 80 and 85 dB,there was no significant difference in PPI％between the model group and the control group(P＞0.05).In the frontal lobe,the expression levels of HDAC3,HDAC4,HDAC8,HDAC9,HDAC10 and Sirt mRNA in the offspring rats in the model group were significantly lower than those in the control group(P＜0.05),while the expression level of HDAC5 mRNA was significantly higher than that in the control group(P＜0.05);there were no significant differences in the expression levels of HDAC1,HDAC2,HDAC6,HDAC7 and HDAC11 mRNA between the model group and the control group(P＞0.05).In the hippocampus,the offspring rats in the model group had significantly lower expression levels of HDAC1,HDAC8 and HDAC10 mRNA and significantly higher expression levels of HDAC2 and HDAC5 mRNA than those in the control group(P＜0.05);there were no significant differences in the expression levels of HDAC3,HDAC4,HDAC6,HDAC7,HDAC9,HDAC11 and Sirt mRNA between the model group and control group(P＞0.05).In the liver tissue,the expression levels of HDAC6 and HDAC10 mRNA of the offspring rats in the model group were significantly lower than those in the control group(P＜0.05);there were no significant differences in the expression levels of HDAC1,HDAC2,HDAC3,HDAC4,HDAC5,HDAC7,HDAC8,HDAC9,HDAC11 and Sirt mRNA between the model group and the control group(P＞0.05).The expression level of HDAC2 mRNA in the hippocampus of offspring rats in the two groups was negatively correlated with PPI％at 75 dB(r=-0.965,P＜0.05),the expression levels of HDAC10 and Sirt mRNA in frontal lobe tissues were positively correlated with PPI％at 75dB(r=0.946,0.925;P＜0.05).Conclusion Pregnancy Poly I:C infection has significant effects on the expression of HDAC family proteins in offspring rats,and which is related to the impairment of early sensory gating,this may provide new ideas for the research in pathogenesis and drug treatment of schizophrenia.

OBJECTIVE To investigate the effects of GSTP1， XRCC1， ABCB1， MTHFR gene polymorphisms on efficacy and toxic effect of chemotherapy regimen containing oxaliplatin in patients with stage Ⅲ and Ⅳ colorectal cancer patients. METHODS Clinical data of 76 patients with stage Ⅲ and Ⅳ colorectal cancer who received chemotherapy regimen containing oxaliplatin （XELOX，FOLFOX） were collected from the Second Affiliated Hospital of Soochow University from September 2018 to March 2020. The correlation of genotypes with progression-free survival （PFS） and toxic effect was analyzed by using univariate and multivariate COX regression model. RESULTS Carriers of the ABCB1 3435T＞C locus C allele （TC/CC） had a significantly higher risk of progression compared to TT genotype patients [HR＝2.39， 95%CI （1.05，5.50）， P＝0.038]. The risk of progression in patients at stage Ⅳ was significantly higher than those at stage Ⅲ [HR＝8.11， 95%CI（3.39，19.40）， P＜0.001]. Chemotherapy regimen， Karnofsky performance status score and tumor site had no significant effect on disease progression （P＞0.05）. Mutations in gene loci were not correlated with adverse reactions （P＞0.05）. CONCLUSIONS Patients carrying ABCB1 TC/CC and receiving chemotherapy regimen containing oxaliplatin have a higher risk of disease progression， which may be associated with longer PFS in patients （TT genotype） with stage Ⅳ colorectal cancer receiving the chemotherapy， while GSTP1， XRCC1， and MTHFR gene polymorphisms have no significant impact.

Objective To evaluate the therapeutic effect of evodiamine(Evo)on atopic dermatitis(AD)in rat models by regulating the cyclic adenosine monophosphate(cAMP)/protein kinase A(PKA)/cAMP response ele-ment binding protein(CREB)signaling pathway.Methods A rat model of AD was established by administration of multiple doses of 2,4-dinitrochlorobenzene(DNCB).The animals were randomly divided into AD group,Evo-low-dose(Evo-L,5 mg/kg)group,Evo-high-dose(Evo-H,10 mg/kg)group,Evo-H+H-89(5 mg/kg)group and dexamethasone(0.1 mg/kg)group.Normal rats were used as the control group and then the degree of skin damage of rats in each group was scored.Abdominal blood was taken to detect the levels of interleukin-4(IL-4),cAMP,and tumor necrosis factor-α(TNF-α)in serum;Skin lesion tissue was collected to detect pathological change,counting of mast cells,PKA/CREB related protein expression and expression of IL-4 and TNF-α mRNA in the tissue.Results Compared with control group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions of AD group were reduced,the severity score of skin lesions,level of IL-4 and TNF-α,epidermal thickness,number of mast cells and mRNA expression of IL-4 and TNF-α in skin lesion tissues were all significantly increased(P＜0.05).Compared with AD group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions in Evo-L group,Evo-H group,and dexamethasone group were increased,the severity score of skin lesions,level of IL-4 and TNF-α,epidermal thickness,number of mast cells,and mRNA expression of IL-4 and TNF-α in skin lesion tissues all reduced(P＜0.05).Compared with the Evo-H group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions in Evo-H+H-89 group was reduced and the severity score of skin lesion,level of IL-4 and TNF-α,epidermal thickness,num-ber of mast cells,and mRNA expression of IL-4 and TNF-α in skin lesion tissues significantly increased(P＜0.05).Conclusions Evo inhibits inflammatory response and pathological damage through regulation of cAMP/PKA/CREB signaling pathway in AD rat models.

Objective:To investigate the prospective association of sleep duration with the development of chronic obstructive pulmonary disease (COPD) in adults in Suzhou.Methods:The study used the data of 53 269 participants aged 30-79 years recruited in the baseline survey from 2004 to 2008 and the follow-up until December 31, 2017 of China Kadoorie Biobank (CKB) conducted in Wuzhong District, Suzhou. After excluding participants with airflow limitation, self-reported chronic bronchitis/emphysema/coronary heart disease history at the baseline survey and abnormal or incomplete data, a total of 45 336 participants were included in the final analysis. The association between daily sleep duration and the risk for developing COPD was analyzed by using a Cox proportional hazard regression model, and the hazard ratio ( HR) values and their 95% CI were calculated. The analysis was stratified by age, gender and lifestyle factors, and cross-analysis was conducted according to smoking status and daily sleep duration. Results:The median follow-up time was 11.12 years, with a total of 515 COPD diagnoses in the follow-up. After adjusting for potential confounders, multifactorial Cox proportional hazard regression analysis showed that daily sleep duration ≥10 hours was associated with higher risk for developing COPD ( HR=1.42, 95% CI: 1.03-1.97). The cross analysis showed that excessive daily sleep duration increased the risk for COPD in smokers ( HR=2.49, 95% CI: 1.35-4.59, interaction P<0.001). Conclusion:Longer daily sleep duration (≥10 hours) might increase the risk for COPD in adults in Suzhou, especially in smokers.

Objective:To investigate the association between sleep status and the risk for coronary heart disease in adults in Suzhou.Methods:Using the baseline and follow up information of 53 269 local residents aged 30-79 years in China Kadoorie Biobank conducted in Wuzhong District, Suzhou, 51 929 subjects were included in this study after excluding those reporting coronary heart disease, stroke and cancer at the baseline survey. A Cox proportional hazards regression model was used to analyze the association of healthy sleep score (0-3 points) and sleep factors (snoring, insomnia, long sleep duration and nap) with the risk for coronary heart disease.Results:The median follow-up time was 11.12 years, and 1 304 individuals were diagnosed with coronary heart disease during the follow-up. After adjusting for potential confounders, occasional snoring ( HR=1.20, 95% CI: 1.04-1.38), usual snoring ( HR=1.17, 95% CI: 1.02-1.33), insomnia disorder ( HR=1.41, 95% CI: 1.12-1.78), daytime dysfunction ( HR=1.56, 95% CI: 1.20-2.03) and perennial nap ( HR=1.37, 95% CI: 1.19-1.59) were associated with increased risk of coronary heart disease. Compared with those with sleep score of 0 - 1 (low sleep quality), the people with sleep score of 3 had reduced risk of coronary heart disease by 26% ( HR=0.74, 95% CI: 0.63-0.87). Stratified analysis showed that the association of healthy sleep score 3 with risk of coronary heart disease was stronger in low physically active individuals (interaction P<0.05). Conclusions:Snoring, insomnia disorders, daytime dysfunction, and perennial napping were all associated with increased risk for coronary heart disease, and keep healthy sleep mode might reduce the risk for coronary heart disease in adults.
