Objective:To explore the application value of P1 response threshold of cortical auditory evoked potential（CAEP） in evaluating the rehabilitation effect of cochlear implant in young children. Methods:Thirty-three young children after cochlear implantation were divided into groups according to hearing age: Group A（hearing age 1-<2 years old） 10 people; Group B（hearing age 2-<3 years old） 13 people; Group C（hearing age 3-<4 years old） 10 people. The subjective assessment was carried out using the assessment tool for hearing-impaired children- "Criteria and Methods for assessing Auditory and language ability of hearing-impaired children" and objective electrophysiological examination was carried out using CAEP to evaluate the rehabilitation effect. SPSS 25.0 software was used for statistical analysis. Results:The results of subjective assessment of auditory ability and language ability in each group showed an increasing trend with the increase of auditory age. In this study, the P1 response threshold of CAEP in CI implanted children had a significant positive correlation with the 2 kHz hearing threshold after intervention, and the P1 response threshold of CAEP was negatively correlated with many items in subjective auditory ability and language ability assessment. Conclusion:The P1 response threshold of CAEP has a stable correlation with the results of speech audiometry, which can effectively and objectively evaluate the postoperative rehabilitation effect of young children with cochlear implantation.

OBJECTIVES: The risk factors and role of mother‒child gut microbiota in pediatric inflammatory bowel disease (PIBD) remain unclear. We aimed to explore the clinical risk factors associated with PIBD, analyze the characteristics of gut microbiota of children and their mothers, and examine the correlation of the microbial composition in mother‒child pairs. METHODS: We conducted a case-control study including children with PIBD and their mothers as the case group, as well as healthy children and their mothers as the control group. Questionnaires were used to collect information such as family illness history and maternal and early-life events. Fecal samples were collected from the children and mothers for microbiota 16S ribosomal RNA (rRNA) sequencing to analyze the composition and its potential association with PIBD. RESULTS: A total of 54 pairs of cases and 122 pairs of controls were recruited. A family history of autoimmune disease and antibiotic use during pregnancy were associated with an increased risk of PIBD, and a higher education level of the father was associated with a decreased risk of PIBD. Children with PIBD and mothers exhibited different gut microbiota compared to healthy children and mothers. Similarities were observed in the gut microbiota of mothers and children in the same groups. Some bacterial biomarkers of mothers discovered in this study had the power to predict PIBD in their offspring. CONCLUSIONS PIBD is influenced by maternal risk factors and has unique gut microbiota characteristics. The mother‒child gut microbiota is closely related, suggesting the transmission and influence of the gut microbiota between mothers and children. This study highlights the potential pathogenesis of PIBD and provides a basis for developing targeted interventions.

Background and objective Malnutrition is commonly associated with poor prognosis in patients with malignant tumors.The neutrophil-to-lymphocyte ratio(NLR)is an indicator of inflammation in the body and predicts the risk of malnutrition in a variety of diseases;however,its association with malnutrition in lung cancer patients is unclear.The aim of this study is to clarify the association between NLR and nutritional status in stage Ⅳ primary lung cancer and to further deter-mine the optimal NLR cut-off that best predicts the risk of malnutrition.Methods A retrospective analysis of 209 patients ad-mitted to the Department of Medical Oncology,Tianjin Medical University General Hospital with a primary diagnosis of stageⅣ lung cancer from May 2019 to February 2021 was performed,and the nutritional risk screening 2002(NRS 2002)was used to examine their nutritional status.Patient demographic information,pathology,Karnofsky performance status(KPS)score,body mass index(BMI),comorbidities and clinical biochemical indicators were also included.The correlation between NLR and NRS 2002 was investigated.Receiver operating characteristic(ROC)curve was used to determine the best NLR cut-off predi cting malnutrition risk.Multivariable Logistic regression was used to assess the association between NLR and malnutrition risk.Results The rate of patients with stage Ⅳ primary lung cancer at nutritional risk was 36.36％(76/209).A significant positive correlation was observed between NLR values and NRS 2002 risk score(r=0.765,P＜0.001).The ROC curve analysis indicated that an NLR of 3.94 was the optimal cut-off for predicting malnutrition risk(area under the curve=0.747,95％CI:0.678-0.815,P＜0.001),which showed a sensitivity of 55％,a specificity of 86％,a positive predictive value of 68％,and a negative predictive value of 77％.Patients in the NLR＞3.94 group had a significantly higher risk of malnutrition compared to those in the NLR≤3.94 group(69.49％vs 23.33％,P＜0.00 1).Furthermore,NLR was identified as a risk factor for malnutrition in stage Ⅳ primary lung cancer patients.Conclusion NLR is associated with the risk of malnutrition in stage Ⅳ primary lung cancer,and NLR can be used as one of the indicators for screening nutritional risk in patients with stage Ⅳ primary lung cancer

Objective:To investigate the interaction of platelet factor 4(PF4)with tumor necrosis factor-α(TNF-α)in the pathoge-nesis of chronic periodontitis(Ⅲ-C).Methods:22 patients with chronic periodontitis(Ⅲ-C)and 22 subjects with periodontal health were recruited.Before and after periodontal treatment,the concentration of PF4 and TNF-α in gingival crevicular fluid(GCF)and ser-um,the amount of PF4 released by platelets after lipopolysaccharide(LPS)stimulated peripheral blood platelets were measured by ELISA.Flow cytometry was used to calculate the number of platelets in GCF before and after treatment.Results:The concentrations of PF4 and TNF-α in the GCF and serum of the patients were higher than those in the periodontal healthy group(P＜0.05).After treat-ment,the concentrations of PF4 and TNF-α in the GCF were significantly lower than those before treatment(P＜0.05),and the con-centrations of PF4 and TNF-α in the serum were unchanged(P＞0.05).After LPS stimulation of the platelets in blood before and after treatment,the concentration of PF4 released by the platelets was much higher in the patients than that in the healthy controls(P＜0.01),and the concentration was significantly lower after periodontal treatment than before treatment(P＜0.01).The number of CD41/CD61 double positive platelets and CD45 negative cells in GCF before periodontal treatment were 85 times and 87 times higher than those in periodontal healthy subjects,respectively(P＜0.01).Conclusion:PF4 and TNF-α have synergistic effect in the patho-genesis of chronic periodontitis.

Cognitive impairment refers to the abnormality of the hippocampus， cortex and other parts of the brain， which is manifested by the decline of cognitive abilities such as learning， memory and attention. With the increase in people's work pressure and bad living habits， the incidence of cognitive impairment is getting higher and higher， which seriously affects people's normal life. However， there are adverse reactions such as gastrointestinal reactions and extrapyramidal reactions in Western drug treatment for cognitive impairment. Therefore， the development of a drug with relatively minimal adverse reactions is of great significance. Traditional Chinese medicine （TCM） has the characteristics of "multi-component， multi-pathway and multi-target"， and the incidence of adverse reactions is relatively low. Studies have shown that the pathogenesis of cognitive impairment is closely related to oxidative stress， inflammation， apoptosis， autophagy and other processes of neurons in the cerebral cortex and hippocampus. Phosphatidylinositol 3-kinase （PI3K）-protein kinase B （Akt） signal pathway plays an important role in the transmission of intracellular and intracellular signals， and in the regulation of cellular inflammation， apoptosis， autophagy， etc. TCM monomers， TCM extracts， and TCM compounds exert anti-inflammatory， antioxidant， anti-apoptotic and autophagy regulation effects by regulating the PI3K/Akt signaling pathway to improve cognitive impairment. This review first summarized the composition and regulatory process of the PI3K/Akt signaling pathway， and then discussed the research progress on the improvement of cognitive impairment through the improvement of oxidative stress， inflammation， apoptosis and autophagy of neurons. Finally， the recent research status of the regulation of this signaling pathway by TCM extracts， TCM monomers and TCM compounds to improve cognitive impairment was summarized. This study provides a theoretical basis for the future study of new TCM related to cognitive impairment.

BACKGROUND:Medical hydrogels are new functional polymer materials with three-dimensional structural networks and excellent biocompatibility,which have been widely studied in the field of tissue engineering and drug carriers,but the research on the combination of medical hydrogels and Chinese medicine for the treatment of diseases based on tissue engineering is still in the early exploration stage.Therefore,through the analysis of the mechanism of the role of medical hydrogels,the integration of medical hydrogels and Chinese medicine in the research of the joint application of the article,can better provide ideas for scientific researchers,and the joint application of Chinese medicine and medical hydrogels is of great significance. OBJECTIVE:To explore the strategy and significance of Chinese medicine combined with medical hydrogel for disease treatment based on tissue engineering research. METHODS:PubMed and CNKI were used to retrieve articles about the application of Chinese medicine combined with medical hydrogel in tissue engineering from January 2010 to November 2022,with the Chinese and English search terms"hydrogel,traditional Chinese medicine,drug carrier,tissue engineering".After the initial screening of all articles according to the inclusion and exclusion criteria,the 61 articles with high relevance were retained for review. RESULTS AND CONCLUSION:(1)Although the application of Chinese medicine combined with medical hydrogel is involved in intra-articular,intra-tissue organ,soft tissue wounds,tissue engineering,etc.,except for the clinical application of Chinese medicine combined with hydrogel dressing for soft tissue injury,other aspects are still in the experimental stage.(2)The development of Chinese medicine combined with medical hydrogel has great potential and development prospects,but there is a certain difficulty in the manufacture of the gel with high-performance requirements,and it is difficult to master the physical and chemical properties precisely.(3)At present,the comprehensive view of injectable hydrogel with the characteristics of easy to use,its joint use of Chinese medicine can be extended to a wider range,can be used for joint,organ,tissue engineering-related disease treatment.Smart hydrogel has high sensitivity and reversible transformation can also meet the use of the special environment.During the combined use of Chinese medicine,it also needs to understand the mechanism of action of Chinese medicine components.(4)The strategy of combining Chinese medicine with medical hydrogels for disease treatment should start with matching the therapeutic effects of Chinese medicine on organs,tissues and cells combined with appropriate types of medical hydrogels to make up for the shortcomings of traditional Chinese medicine delivery methods and frequent drug delivery.In tissue engineering,hydrogels can be loaded with stem cells after Chinese medicine intervention,or with both Chinese medicine and stem cells for disease treatment.(5)In future research of combined Chinese medicine and medical hydrogel application,we also need to consider:we should ensure that the biological properties of medical hydrogel can be quantified,and grasp the characteristics of hydrogel with different manufacturing processes of different materials to produce the required medical hydrogel that meets the application conditions.In Chinese medicine,we need to comprehensively understand and analyze the therapeutic effects and application mechanisms of known Chinese medicine monomer and Chinese medicine compound extracts,so as to achieve a more perfect combination between Chinese medicine and medical hydrogel under a more clear mechanism.With the continuous improvement of medical science and technology innovation,the medical hydrogel can be innovatively combined with other traditional treatment methods of Chinese medicine,such as acupuncture,massage,cupping and so on,to be used from multiple angles.
