Programmed death-1 (PD-1) is an inhibitory immune checkpoint that binds to programmed death-ligand 1 (PD-L1) to regulate the immune response and maintain immune system homeostasis of the immune system. Through overexpression of PD-L1, tumor cells bind to PD-1 on the surface of immune cells, inhibiting the activity and function of immune cells, leading to immune escape of cancer cells and tumor progression. Gastrointestinal cancer is a common malignancy with a high mortality rate worldwide, and the effectiveness of current systematic treatment options is limited. In recent years, immune checkpoint inhibitors (ICIs) such as PD-1/PD-L1 inhibitors have attracted much attention in cancer therapy. Immunotherapy has been incorporated into the treatment of some gastrointestinal malignancies. Different from traditional treatment, it uses various means to stimulate and enhance the immune function of the body to achieve the therapeutic purpose of controlling and eliminating tumor cells. However, although PD-1/PD-L1 inhibitors have shown potential in the treatment of gastrointestinal tumors, the efficacy of single inhibitor therapy is limited, which may be due to the ability of tumors to escape immune attack through other pathways after inhibitor treatment, or the presence of other immunosuppressive factors. For example, PD-1 and PD-L1 inhibitors can be combined with other immune checkpoint drugs, molecularly targeted drugs, or chemotherapy drugs to simultaneously act on different immune pathways and improve the comprehensive effect of immunotherapy. However, to achieve an effective combination therapy, we need to delve into the specific mechanisms of action of the PD-1/PD-L1 axis in the development and progression of gastrointestinal tumors, which can help to develop the best treatment strategy and provide individualized treatment options for the appropriate patient population. Therefore, future studies should focus on the regulatory mechanisms of PD-1/PD-L1 axis and evaluate the therapeutic effects of different treatment combinations on gastrointestinal tumors. In this paper, we review the research progress of PD-1/PD-L1 axis in tumorigenicity and its mechanism, and review the single and combined treatment strategies of PD-1 and PD-L1 inhibitors in gastrointestinal tumors.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

ObjectiveThe aim of this study is to investigate the role of salidroside in regulating the miR-1343-3p/MAP3K6 （mitogen-activated protein kinase kinase kinase 6）/MMP24 （membrane-type matrix metalloproteinase 24） signaling pathway to inhibit gastric cancer cell proliferation and migration. MethodsHuman gastric cancer cells （MGC-803） were divided into several groups based on different salidroside concentrations： a control group （0 μmol/mL）， a low-dose group （6 μmol/mL）， a medium-dose group （12 μmol/mL）， and a high-dose group （24 μmol/mL）. The anti proliferative effects of salidroside on human gastric cancer cells were evaluated by CCK-8 assay. Clonogenic assay was used to examine the effects of salidroside drugs on the clonogenic ability of human gastric cancer cells. Transwell assay was performed to detect the effect of salidroside on the invasive ability of human gastric cancer cells. Cell scratch assay was performed to detect the effect of salidroside on the migration ability of human gastric cancer cells. The miRNA expression profile was analyzed by using RNA-seq in cancer cells for 24 h after salidroside treatment. The differentially expressed miRNAs were clustered and their target genes were predicted. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） were used to analyze and predict the functions of these target genes， and the interaction networks were established. Immunocytofluorescence was used to detect the expression of target proteins， and the transcription of candidate genes was detected by q-PCR. ResultsCCK-8 cytotoxicity experiments showed that salidroside inhibited the proliferation of MGC-803 cells （P < 0.01）. Cell cloning experiments showed that salidroside reduced the clonal formation capacity of MGC-803 cells （P < 0.000 1）. Cell invasion experiments showed that salidroside reduced the MGC-803 cell invasion capacity （P < 0.000 1）. Cell scratch experiments showed that salidroside reduced the cell migration capacity （P < 0.000 1）. RNA-seq findings showed that the expression of 44 miRNAs changed significantly after salidroside treatment in cancer cells （P < 0.05）. Bioinformatic analysis showed that there were 1 384 target mRNAs corresponding to the differentially expressed miRNAs， and the expression of the tumor suppressor miR-1343-3p was significantly upregulated after salidroside treatment （P < 0.01），and resulted in down-regulated transcription of MAP3K6 and MMP24 genes which are related to the proliferation and migration of cancer cells （P < 0.05）. Immunofluorescence experiments demonstrated that salidroside reduced protein expression levels in MAP3K6 and MMP24 genes （P < 0.000 1）. q-PCR experiments showed that salidroside reduced the mRNA expression level of MAP3K6 and MMP24 genes （P < 0.000 1）， while miRNA expression in miR-1343-3p gene was upregulated （P < 0.000 1）. ConclusionSalidroside regulates the miRNA-1343-3p/MAP3K6/MMP24 signaling molecules to inhibit proliferation and invasion of gastric cancer cells.

Objective: To analyze the clinical and molecular diagnostic status of Fanconi anemia (FA) in China. Methods: The General situation, clinical manifestations and chromosome breakage test and genetic test results of 107 pediatric FA cases registered in the Chinese Blood and Marrow Transplantation Registry Group (CBMTRG) and the Chinese Children Blood and Marrow Transplantation Registry Group (CCBMTRG) from August 2009 to January 2022 were analyzed retrospectively. Children with FANCA gene variants were divided into mild and severe groups based on the type of variant, and Wilcoxon-test was used to compare the phenotypic differences between groups. Results: Of the 176 registered FA patients, 69 (39.2%) cases were excluded due to lack of definitive genetic diagnosis results, and the remaining 107 children from 15 hospitals were included in the study, including 70 males and 37 females. The age at transplantation treatment were 6 (4, 9) years. The enrolled children were involved in 10 pathogenic genes, including 89 cases of FANCA gene, 7 cases of FANCG gene, 3 cases of FANCB gene, 2 cases of FANCE gene and 1 case each of FANCC, FANCD1, FANCD2, FANCF, FANCJ, and FANCN gene. Compound heterozygous or homozygous of loss-of-function variants account for 69.2% (72/104). Loss-of-function variants account for 79.2% (141/178) in FANCA gene variants, and 20.8% (37/178) were large exon deletions. Fifty-five children (51.4%) had chromosome breakage test records, with a positive rate of 81.8% (45/55). There were 172 congenital malformations in 80 children.Café-au-Lait spots (16.3%, 28/172), thumb deformities (16.3%,28/172), polydactyly (13.9%, 24/172), and short stature (12.2%, 21/172) were the most common congenital malformations in Chinese children with FA. No significant difference was found in the number of congenital malformations between children with severe (50 cases) and mild FANCA variants (26 cases) (Z=-1.33, P=0.185). Conclusions: FANCA gene is the main pathogenic gene in children with FA, where the detection of its exon deletion should be strengthened clinically. There were no phenotypic differences among children with different types of FANCA variants. Chromosome break test is helpful to determine the pathogenicity of variants, but its accuracy needs to be improved.
