ObjectiveTo investigate the effects of Huanglian Jiedutang （HLJDT） on cognitive function in mice with ischemic stroke （IS） and to elucidate whether its neuroprotective effects are mediated by inhibition of the nuclear factor-κB （NF-κB） signaling pathway and subsequent suppression of NF-κB-regulated neuronal apoptosis. MethodsAn IS model was established using middle cerebral artery occlusion （MCAO）. Sixty C57BL/6J mice were randomly assigned to five groups （n =12 per group）， i.e.， sham operation， model， HLJDT low-dose （3.9 g·kg^-1·d^-1）， HLJDT high-dose （7.8 g·kg^-1·d^-1）， and Ginkgo biloba extract （GBE， 31.2 mg·kg^-1·d^-1）. Post-operatively， neurological deficit scores （Longa score）， cerebral infarct volume assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and brain water content were evaluated. Learning and memory were assessed using new object recognition （NOR） and fear conditioning （FC） tests. Hippocampal pathology was examined via hematoxylin and eosin （HE） staining. Immunofluorescence detected expression of glial fibrillary acidic protein （GFAP， astrocyte marker）， cellular oncogene Fos （c-Fos， neuronal activation marker）， and glutamate decarboxylase 65 （GAD65）. Western blot measured nuclear factor-κB inhibitor protein α （IκBα）， phosphorylated IκBα （p-IκBα）， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， ionic calcium binding adapter molecule 1 （Iba-1）， tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and apoptosis-related proteins， such as cleaved cysteinyl aspartate-specific protease 3 （Caspase-3）， B-cell lymphoma 2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Real-time quantitative PCR （Real-time PCR） was used to assess mRNA levels of Iba-1， TNF-α， IL-1β， NF-κB p65， cleaved Caspase-3， Bax， and Bcl-2. ResultsCompared with the sham group， the model group exhibited significantly increased neurological deficit scores， brain water content， and cerebral infarct volume （P<0.01）. Hippocampal CA1 neurons were disorganized， showing nuclear pyknosis and karyolysis. NOR exploration time and FC freezing time were significantly reduced （P<0.01）. GFAP and c-Fos expression were increased， while GAD65 expression was decreased （P<0.01）. Cleaved Caspase-3 and Bax were upregulated， Bcl-2 was downregulated， and the Bax/Bcl-2 ratio was elevated （P<0.01）. Expression levels of p-IκBα， p-NF-κB p65， IL-1β， TNF-α， and Iba-1 were significantly increased （P<0.01）. Compared with the model group， HLJDT high-dose， low-dose， and GBE groups showed significant improvements in all parameters （P<0.01）. Among them， the HLJDT high-dose group showed the most pronounced neuronal structural recovery and superior performance in NOR and FC tests （P<0.01）. In this group， GFAP and c-Fos decreased， GAD65 increased （P<0.01）， apoptosis-related protein expression was reversed， and NF-κB signaling and related inflammatory factor expression were suppressed （P<0.01）. ConclusionHLJDT ameliorates cognitive dysfunction in mice after IS， potentially by inhibiting the NF-κB signaling pathway， thereby reducing neuroinflammation and hippocampal neuronal apoptosis.

To report diagnosis and treatment of a patient with rectal cancer and synchronous liver metastases, accompanied by severe coronary artery stenosis and cardiac insufficiency, and to provide a reference for clinical decision-making in such cases through introducing the treatment contradiction, the choice of systemic treatment plan and the timing of operation, and the final outcome. After definitive diagnosis, the patient received systemic therapy with cetuximab＋irinotecan＋oxaliplatin＋raltitrexed, and along with oral medication to improve cardiac function, followed by elective coronary revascularization. After revascularization, the cardiac function of patient was fully improved. And the tumor lesion was effectively controlled after antitumor therapy. Once the cardiac condition of patient stabilized, two-stage surgical resection of the primary rectal cancer and liver metastases was performed, ultimately achieving tumor-free status, and discharged.

Objective To investigate the improvement effect of Necrostatin-1 (Nec-1) on mouse models with immune checkpoint inhibitor (ICI) -associated myocarditis (ICIAM) and potential mechanism. Methods Ten male BALB/c mice aged 6-8 weeks were selected to construct the ICIAM models. The echocardiography and serum myocardial injury markers were used to assess cardiac function of mice. The levels of inflammatory markers including tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were detected by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR), respectively. Hematoxylin-eosin (HE) staining was used to evaluate myocardial inflammation, and Masson staining was used to evaluate myocardial fibrosis. The expressions of myocardial necroptosis proteins including receptor-interacting protein kinase 1 (RIP1), RIP3, mixed lineage kinase domain-like protein (MLKL) and their phosphorylated forms were detected by Western blotting. The spleen lymphocytes were extracted and co-cultured with HL-1 cell line. Cell viability was measured by cell counting kit-8 (CCK-8). The release of reactive oxygen species (ROS) and changes of mitochondrial membrane potential were observed. RIP1, RIP3, MLKL and their phosphorylated forms were determined. The levels of markers of oxidative stress, including malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), were measured. Results Nec-1 significantly improved the cardiac function injury of mice induced by ICI, and inhibited the release of TNF-α and IL-1β in plasma of ICIAM mice (P＜0.001); inhibited expressions of phosphorylated RIP1, RIP3 and MLKL (P＜0.05); decreased MDA activity, and increased SOD and GSH-Px activity (P＜0.001). In HL-1 cells, Nec-1 intervention inhibited the RIP1-RIP3-MLKL pathway (P＜0.05), improved decrease of the cell viability induced by lymphocytes (P＜0.001), decreased ROS release, increased mitochondrial membrane potential, inhibited MDA activity, and increased SOD and GSH-Px activities (P＜0.001). Conclusions Necroptosis plays an important role in the occurrence and development of ICIAM，but Nec-1 could alleviate the progression of ICIAM by inhibiting necroptosis induced by oxidative stress in cardiomyocytes; RIP1 maybe a new target in treatment of ICIAM.

ObjectiveTo analyze the impact of maternal postpartum depression (PPD) at 2 months postpartum on caregiving for infants aged2 to 24 months, and to provide a scientific basis for future maternal and infant healthcare services. MethodsBased on the Shanghai Maternal-Child Pairs Cohort, 1 060 mother-child pairs were selected from those fully participating in follow-up visits at 2, 6, 12, and 24 months postpartum. Pregnancy and childbirth-related information was collected using standardized questionnaire surveys and hospital obstetric and maternity records. The Edinburgh postpartum depression scale was used to assess the maternal postpartum depressive symptoms at 2 months postpartum. At 2, 6, 12, and 24 months postpartum, questionnaire survey was used to evaluate the maternal responsiveness in caregiving and the provision of early learning opportunities for infants. Scores for responsive caregiving and early learning opportunities at 2, 6, 12, and 24 months were grouped based on the 25th percentile (P₂₅) of total scores. The mixed-effects model was used to analyze the longitudinal impact of maternal postpartum depression at 2 months on the caregiving of 2 to 24-month-old infants. ResultsThe longitudinal results from the mixed-effects model did not show an impact of maternal PPD on infant responsive caregiving within 12 months and early learning opportunities within24 months. However, cross-sectional analysis revealed that, compared to the non-PPD group, the risk of low responsive caregiving at 2 months in the PPD group was 93% higher (OR=1.931, 95%CI: 1.113‒3.364, P=0.019). The risks for low provision of early learning opportunities at2 months and 24 months increased by 59% (OR=1.589, 95%CI: 1.082‒2.324, P=0.017) and 60% (OR=1.598, 95%CI:1.120‒2.279, P=0.010), respectively. ConclusionMaternal postpartum depression increases the risk of low responsive caregiving at 2 months, but its long-term effects warrant further research.

Objective:To assess the epidemic characteristics of serum of viral hepatitis B infection ranging in age from 1 to 69 years old in Jilin province in 2024. The genotypes of hepatitis B virus-infected individuals were determined.Methods:In 2024，2 313 people ranging in age from 1 to 69 years old in Jilin province were selected by using multi-stage random sampling method for field epidemiological investigation of hepatitis B. The serum samples were collected and detected for the hepatitis B virus（HBV）surface antigen（HBsAg），HBV surface antibody（HBsAb），HBV core antibody（HBcAb），HBV E antigen（HBeAg）and HBV E antibody（HBeAb）by ELISA，and the data were analyzed by the national epidemiological dynamic data collection platform，SPSS 18.0 software. Genotyping is conducted based on the internationally recognized large S region gene fragment.Results:The vaccination rates for hepatitis B among people aged 1-4，5-14，15-29 and 30-69 were 97.00%，94.66%，74.59% and 2.88%，respectively. There were significant differences in hepatitis B vaccination rates across age groups surveyed in 2024（ χ2=1 041.41， P<0.05）. In 2024，the HBsAg carrying rate，HBsAb positive rate，HBV infection rate，HBeAb positive rate and HBeAg positive rate of people in Jilin province were 0. 86%，47.99%，2.25%，5.58% and 5.14%，respectively. The genotype of hepatitis B virus in the infected person is B2 and C2. Conclusions:In 2024，the indicators of HBV infection in Jilin province were good. The highest rate of hepatitis B infection was 11.54% in people with 30-69 years of age and the high vaccination rate of people should continue to be maintained，and the vaccination of hepatitis B vaccine for adults should be strengthened to reduce the risk of infection in these susceptible groups.

The occurrence and development of colitis associated cancer(CAC)is closely related to the intestinal microenvironment.Traditional Chinese medicine(TCM)posits that"spleen deficiency"is the basic pathogenesis of colon cancer occurrence and development,and plays a key role in the process of"inflammation-cancer transformation".However,at present,the pathogenesis of spleen in the course of its pathogenesis is mostly focused on the body's own system,and few are discussed in combination with the theoretical basis of TCM's holistic view of"correspondence between man and nature".The spleen,as a taiyin organ with a damp-earth nature,relies on yang energy for movement,inherently averses dampness,and governs ascending qi.Late summer is mainly wet,which can easily obstruct the spleen qi,curb the upward trend and stop the spread opportunity when the wettability sticks and has a downward trend.This suggests that the influence of external environmental factors on the body should be comprehensively considered in the study of the classical process of"intestinal flora disturbance-inflammatory microenvironment formation-tumor formation"experienced in the pathogenesis of CAC.Based on the complementarity,mutual penetration and mutual promotion of the theories of traditional Chinese and western medicine,this paper discusses the role of external environmental factors in the occurrence of CAC focused on the mechanism of macrophage polarization imbalance during the formation of tumor inflammatory microenvironment,and provides a basis for the theoretical integration and development of TCM"time-dependent treatment"prevention and treatment strategies.

Isocitrate dehydrogenase(IDH)wild-type glioma is a type of highly invasive brain tumor with poor prognosis and a high recur-rence rate.The recurrence process is driven by multiple complex and interwoven factors.Although the current standard treatment regi-mens can temporarily alleviate patients'symptoms,they still face significant challenges in effectively preventing tumor recurrence.The re-currence mechanism of this tumor is intricate and covers multiple aspects such as genomic instability,maintenance of stem cell characterist-ics and mesenchymal transformation,as well as dynamic changes in the tumor microenvironment.This article aims to comprehensively sum-marize the recurrence mechanism of glioblastoma and deeply explore potential countermeasures targeting these mechanisms,hoping to open up new perspectives and approaches for the treatment of recurrent tumors.

OBJECTIVE To explore the risk factors for peritoneal dialysis-associated peritonitis(PDAP)in the type 2 diabetes mellitus patients complicated with renal anemia and construct the risk prediction model so as to provide references for clinical diagnosis and treatment of PDAP.METHODS A total of 142 type 2 diabetes mellitus patients who were complicated with renal anemia and underwent peritoneal dialysis in nephrology department of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine from Jan.2017 to Dec.2023 were recrui-ted as the research subjects and were divided into the peritonitis group with 68 cases and the non-peritonitis group with 74 cases according to the status of complication with PDAP.The related data were collected,the univariate a-nalysis and binary logistic regression analysis were performed,the risk prediction model was established,and the obtained model was visualized for further analysis.RESULTS The univariate analysis showed that the age and lev-els of glycosylated hemoglobin,triglyceride and fibrinogen were higher in the peritonitis group than in the non-per-itonitis group;the levels of serum potassium,serum iron and total iron binding capacity of the peritonitis group were lower than those of the non-peritonitis group,and there were significant differences(all P＜0.05).The bina-ry logistic regression analysis indicated that glycosylated hemoglobin no less than 7.00％(OR=4.047,95％CI:1.663 to 9.847,P=0.002),no less than 60 years of age(OR=2.181,95％CI:1.039 to 4.578,P=0.039),triglyc-eride greater than 1.47 mmol/L(OR=2.393,95％CI:1.140 to 5.026,P=0.021)and serum iron less than 7.90μmol/L(OR=2.582,95％CI:1.188 to 5.608,P=0.017)were the risk factors for the PDAP in the type 2 diabe-tes mellitus patients complicated with renal anemia.CONCLUSIONS The glycosylated hemoglobin no less than 7.00％,no less than 60 years of age,triglyceride greater than 1.47 mmol/L and serum iron less than 7.90 μmol/L are the risk factors for PDAP in the type 2 diabetes mellitus patients complicated with renal anemia.The risk pre-diction model can be established based on the above factors,and the intervention measures should be actively taken so as to reduce the risk of PDAP and improve the quality of life.

Objective:To explore the clinical significance of trisomy 7 signaled by non-invasive prenatal testing (NIPT).Methods:Pregnant women with high risk for trisomy 7 by NIPT from January 2017 to December 2023 were selected as the study subjects, and the results of prenatal diagnosis and follow-up were analyzed. Literature related to pregnant women with a high risk for trisomy 7 by NIPT from January 2016 to July 2024 was retrieved from China Biomedical Literature Database, Wanfang Database, China National Knowledge Infrastructure and PubMed database. Relevant information such as the incidence of trisomy 7 by NIPT, positive predictive value (PPV), and pregnancy outcomes were collected. This study has been approved by the Medical Ethics Committee of Lianyungang Maternal and Child Health Care Hospital (Ethics No. JS2022010).Results:A total of 51 women with a high risk for trisomy 7 by NIPT were identified. Thirty-two of them had chosen chromosomal microarray analysis (CMA) of amniotic fluid cells, and 1 case of mosaic trisomy 7 was detected, which had yielded a PPV of 3.13%. Four women had opted termination of pregnancy, 1 had miscarriage, 4 had pre-term and/or low weight birth, whilst the remaining 42(82.4%) had full-term delivery. In total 19 literature were retrieved, which had involved 278 cases of trisomy 7 signaled by NIPT, among which 5 fetuses with mosaic trisomy 7 (3.14%) were confirmed. Among the 211 women with follow-up outcomes, 2 (0.95%) had intrauterine growth restriction, 3 (1.42%) had abnormal fetal structure detected by ultrasound, 2 (0.95%) had miscarriage, 9 (4.27%) underwent pregnancy termination, 28 (13.27%) had preterm and/or low weight birth, whilst 167 (79.14%) had normal delivery. In 18 cases, chromosomal analysis of placental tissue was carried out, and 17 were confirmed to have mosaicism trisomy 7.Conclusion:The PPV for trisomy 7 signaled by NIPT is extremely low. Although most of such women had a full term delivery, adverse pregnancy outcomes may still occur in a minority of cases. Clinicians should provide adequate genetic counseling for such women and recommend appropriate prenatal diagnosis strategies and optimal perinatal management plans.

Objective:To explore the spectrum of genetic variants and phenotypes of Phenylalanine hydroxylase deficiency (PAHD) in Lianyungang area and the correlation between genotype and phenotypes among the patients.Methods:Eighty children with Hyperphenylalaninemia (HPA) diagnosed at the Lianyungang Branch of Jiangsu Provincial Newborn Screening Center between January 2015 and December 2022 were enrolled. Peripheral blood samples were collected for genetic analysis using next generation sequencing (NGS), Sanger sequencing, and multiplex ligation-dependent probe amplification (MLPA) to identify the variants of PAH gene. Clinical and phenotypic data were concurrently analyzed to investigate the correlation between the types of PAH gene variant and phenotypes. This study was approved by the Medical Ethics Committee of Lianyungang Maternal and Child Health Care Hospital (Ethics No.: XM2022041). Results:① PAH variants were identified in 93.75% (75/80) of the children, classified as PAHD cases, while 6.25% (5/80) harbored PTS variants. ② Of the 150 PAH alleles from 75 PAHD children, a total of 152 variants (55 distinct types) were detected, with a detection rate of 100%. 80.26% (122/152) were located in exons, with the main types of variants were missense variants (67.11%, 102/152). 53.29% (81/152) of coding sequence variants occurred in the PAH gene catalytic center region of PAH protein, while 19.74% (30/152) of variants involved non-coding sequences. ③The phenotypes of the 75 PAHD children were evenly distributed. The rescreening Phe concentrations and Phe/Tyr ratios of classic-phenylketonuria (CPKU) and mild-phenylketonuria (MPKU) patients were markedly higher than initial screening values ( P<0.001, P<0.001; P=0.004, P=0.016). The genotypes of the PAHD patients mostly occurred as compound heterozygotes, and different mutation positions and variant types significantly affect the phenotype ( P=0.042, P=0.045). ④APV/GPV genotype-phenotype analysis of 61 patients showed high consistency between predicted and actual phenotypes ( κ=0.755, P<0.001). Conclusion:PAH variants were detected in the most of HPA children in Lianyungang area. The location and type of PAH variants were related to the severity of the phenotype, and the non-coding sequence variants and non-missense variants may aggravate the phenotype, and the APV/GPV model predicted the phenotype was highly consistent with the actual phenotype.
