Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Objective:To analyze the evaluation of the application effect and deficiency of nurses acting as standardized parents in the graduation examination of standardized residency training of pediatrics and further improve and promote the level of standardized parents.Methods:A questionnaire survey was used to collect the scores of nurse standardized parents by students and examiners who took part in the graduation examination of standardized residency training of pediatrics in 2021. And the self-evaluation scores of standardized parents were collected. Counting data were represented by the number of cases and composition ratio. A Chi-square test was used to compare the rates.Results:A total of 125 questionnaires from students and 37 questionnaires from nurse standardized parents were collected, and the overall satisfaction (very satisfied + satisfied) of standardized parents reached 121 (96.80%). In the three dimensions of simulation ability, compliance with question-and-answer rules, and simulated attitude, students believed that the consistency between standardized parents and actual parents in simulated altitude was lower than that in the simulation ability and compliance with question-and-answer rules ( P=0.007, P=0.001). The overall satisfaction of standardized parents (very satisfied + satisfied) reached 87.38% (388/444). There were 26 (70.27%) nurse standardized parents who had the lowest satisfaction with their own performance ability, followed by 28 (75.68%) cases of imitation ability and 30 (81.08%) cases of adaptability. Conclusions:It is feasible to adopt nurse standardized parents in the assessment of standardized residency training of pediatrics, and both students and examiners have higher satisfaction. The next step is to improve the training of nurses standardized parents in the attitude of simulation and, at the same time, enhance the training of imitation ability and adaptability, so as to further expand the construction of standardized parents.

Objective:To explore the relationship between the location of puncture points and the occurrence of complications in X-ray assisted percutaneous fluoroscopic gastrostomy (PFG).Methods:The retrospective and descriptive study was conducted. The clinical data of a total of 67 patients, including the gender, age, etiology, nutritional status. All data of 67 patients who received with X-ray assisted PFG surgery during the period from January 2021 to January 2023 in Xuanwu Hospital of Capital Medical University were retrospectively analyzed. There were 42 males and 25 females, aged (57.3±12.6) years, ranging from 22 to 90 years old. The technical success rate, distribution of puncture points, and incidence of complications were described. The relationship between different gastric types and puncture sites and complications was analyzed. Measurement data with normal distribution were represented as mean±standard deviation ( ± s). Count data were represented as numbes and Pearson chi-square test was used between groups. Results:A total of 67 patients with dysphagia were included in our study, all of whom underwent X-ray assisted PFG in our institution. The technical success rate was 100%. In the empty state, the puncture point of 30 patients was located at the midpoint of the gastric cavity, 28 cases were leaned towards to the greater curvature, and 9 cases were leaned towards to the lesser curvature. No operation-related severe complications occurred, such as acute gastrointestinal bleeding and perforation. A total of 7 patients experienced varied degree of pain complication during follow-up period, including 5 cases of waterfall type stomach, which showed significant differences with other gastric types ( χ2=3.889, P=0.049). Pain complication of 6 patients was related to the location of the puncture point, with 5 cases leaning towards to the greater curvature and 1 case leaning towards to the lesser curvature. Conclusions:PFG surgery is safe and reliable, the gastric wall puncture point is not completely consistent between the empty and dilated gastric state. The occurrence of postoperative pain may be related to the patient′s gastric type pearson and changes in the position of the puncture point at the empty gastric state.

Objective To explore clinical effect of distal tibial tubercle-high tibial osteotomy(DTT-HTO)in treating knee osteoarthritis(KO A)with medial meniscus posterior root tear(MMPRT).Methods A retrospective analysis was performed on 21 patients with varus KOA with MMPRT from May 2020 to December 2021,including 3 males and 18 females,aged from 49 to 75 years old with an average of(63.81±6.56)years old,the courses of disease ranged from 0.5 to 18.0 years with an average of(5.9±4.2)years,and 4 patients with grade Ⅱ,14 patients with grade Ⅲ,and 3 patients with grade Ⅳ according to Kellgren-Lawrence;14 patients with type 1 and 7 patients with type 2 according to MMPRT damage classification.The distance of medi-al meniscusextrusion(MME)and weight-bearing line ratio(WBLR)of lower extremity were compared before and 12 months after operation.Visual analogue scale(V AS),Western Ontarioand and McMaster Universities(WOMAC)osteoarthritis index,and Lysholm knee score were used to evaluate knee pain and functional improvement before operation,1,6 and 12 months after operation,respectively.Results Twenty-one patients were followed up for 12 to 18 months with an average of(13.52±1.72)months.MME distance was improved from(4.99±1.05)mm before operation to(1.87±0.76)mm at 12 months after operation(P＜0.05).WBLR was increased from(15.49±7.04)％before operation to(62.71±2.27)％at 12 months after operation(P＜0.05).VAS was decreased from(7.00±1.14)before operation to(2.04±0.80),(0.90±0.62)and(0.61±0.50)at 1,6 and 12 months after operation.WOMAC were decreased from preoperative(147.90±9.88)to postoperative(103.43±8.52),(74.00±9.54)and(47.62±9.53)at 1,6 and 12 months,and the difference were statistically significant(P＜0.05).Lysholm scores were increased from(46.04±7.34)before oepration to(63.19±8.93),(81.10±6.41)and(89.29±3.04)at 1,6 and 12 months after operation(P＜0.05).Conclusion For the treatment of varus KOA with MMPRT,DTT-HTO could reduce medial meniscus pro-trusion distance,improve the ratio of lower limb force line,and effectively reduce knee pain and improve knee joint function.

Objective:To observe the inhibitory effect of dobutamine on proliferation of FLT3-ITD mutated acute myeloid leukemia(AML)cells and explore the feasibility of dobutamine as a monotherapy or in combination with quizartinib for the treatment of this type of AML.Methods:FLT3-ITD mutant cell lines MOLM13 and MV4-11 were cultured in vitro and divided into control group,dobutamine treatment group,quizartinib treatment group,and dobutamine combined with quizartinib treatment group.Cell viability,ROS levels,and apoptosis rate were detected by CCK-8,Flow cytometry,respectively,as well as the expression of YAP1 protein by Western blot.Results:Both dobutamine and quizartinib inhibited the proliferation of FLT3-ITD mutant AML cell lines.Compared with the control group,the dobutamine group exhibited a significant increase in ROS levels(P＜0.01),an increase in apoptosis rates(P＜0.05),and a decrease in YAP1 protein expression(P＜0.05).Compared with the dobutamine group,the combination of quizartinib and dobutamine significantly reduced cell viability(P＜0.05),increased ROS levels(P＜0.01),and decreased YAP1 expression(P＜0.05).Conclusion:Dobutamine as a monotherapy can inhibit the proliferation of FLT3-ITD mutated AML cells,inducing apoptosis.Additionally,the combination of quizartinib enhances the targeted inhibitory effect on FLT3-ITD mutated AML.The mechanism may involve the inhibition of YAP1 protein expression in AML cells of this type,leading to an increase in ROS levels and exerting its anti-tumor effects.

Objective:To summarize the clinical phenotype and genetic characteristics of a case of autosomal dominant mental retardation-42 (MRD42) caused by GNB1 gene mutation. Methods:The clinical and genetic data of a case of MRD42 caused by a GNB1 gene missense mutation diagnosed in the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University in March 2023 were retrospectively analyzed. The child was followed-up, the child′s data were summarized, and related literature was reviewed. Results:The patient is a 6-month-old female infant, who was admitted to hospital because of "developmental delay for 3 months, intermittent convulsions for 1 month". The clinical manifestations included generalized tonic-clonic seizures, focal seizures, intellectual disability, delayed language and motor development. Long-term video electroencephalogram showed slightly slower background activity, bilateral occipital spike and wave discharges, multispike and wave complexes during sleep. Three focal onset seizures were captured. Cranial magnetic resonance imaging suggested that the subarachnoid space of the bilateral frontotemporal areas was slightly wide. Chromosome karyotype and copy number variation analysis showed no abnormality. The results of whole exon sequencing showed a de novo heterozygous missense mutation in the GNB1 gene [NM_002074:c.155(exon5)G>A;p.Arg52Gln], which had not been reported. The seizure was effectively controlled by function rehabilitation training and anti-epileptic drug therapy. Conclusions:MRD42 is a rare autosomal dominant disorder caused by mutation in the GNB1 gene. The clinical manifestations include infantile-onset seizures, mental retardation, speech and motor development delay, etc. The de novo heterozygous missense mutation in the GNB1 gene c.155G>A(p.Arg52Gln) is the genetic cause of the proband.

Objective:To summary the clinical phenotype and genotype characteristics of 2 cases of autosomal dominant mental retardation (MRD) caused by TRIO gene variation. Methods:Retrospective study of the clinical data of 2 cases of autosomal dominant MRD caused by TRIO gene mutations diagnosed at the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University in April 2019 and January 2023 was conducted. The clinical features were summarized and gene analysis and follow-up were carried out. Results:The 2 patients were 6 years and 5 months old and 5 months old males, respectively. Clinical manifestations included seizures, cognitive and motor disorders, low intelligent development; case 1 had microcephaly, attention deficit disorder, ataxia, and aggressive behavior, and case 2 had macrocephaly. Brain magnetic resonance imaging revealed cerebellar atrophy in case 1, and non-specific dilation of the subarachnoid space and hypoplasia of the corpus callosum in case 2. Analysis of chromosome karyotype and chromosome copy number variation in 2 children showed no abnormalities. Whole exome sequencing revealed novel missense mutations in the TRIO gene in both patients [NM_007118:c.4289C>A(p.Thr1430Lys), c.4111C>A(p.His1371Asn), respectively]. The application of rehabilitation function training and a variety of anti-seizure medications can not fully and effectively control the seizure. Conclusion:TRIO gene c.4289C>A(p.Thr1430Lys), c.4111C>A(p.His1371Asn) de novo missense variants were the genetic etiology of the 2 probands,causing rare autosomal dominant MRD type 44 and 63.

Objective:To summarize the clinical diagnosis and treatment process of breast implant associated-anaplastic large cell lymphoma (BIA-ALCL) in symptomatic patients with textured breast implants in Peking Union Medical College Hospital in order to provide reference for the management of such patients in China.Methods:From January 2019 to September 2021, 23 symptomatic patients with textured breast implants were admitted to the Peking Union Medical College Hospital, aged 29-52 years, with an average of 36.2 years. All patients agreed to remove the prosthesis by surgery, and accepted cytology, flow cytometry, and immunohistochemical examination of the fluid around the implants and capsule tissue before or during the operation to complete the BIA-ALCL screening process.Results:All 23 patients presented with unilateral periprosthetic fluid accumulation, with fluid volume ranging from 20 to 130 ml, of which 7 cases were combined with periprosthetic contracture. No tumor cells were found in the pathological findings of effusion and the capsule tissue, and the BIA-ALCL pathologic screening results (CD 30 and ALK) were all negative. No bleeding, infection, wound dehiscence and other complications occurred after the operation.Conclusions:A personalized clinical process should be developed for symptomatic patients with textured breast implants. Attention should be paid to imaging and pathological examinations.

Objective:To investigate the influencing factors for splenomegaly secondary to acute pancreatitis (AP) and construction of a nomogram prediction model.Methods:The retrospective case-control study was conducted. The clinicopathological data of 180 patients with AP who were admitted to Xuanwu Hospital of Capital Medical University from December 2017 to December 2021 were collected. There were 124 males and 56 females, aged (49±15) years. Among them, 60 AP patients who developed secondary splenomegaly were taken as the case group, including 48 males and 12 females, aged (47±13)years, and the rest of 120 cases of AP without secondary splenomegaly were taken as the control group, including 76 males and 44 females, aged (50±16)years. Observation indicators: (1) occurrence and clinical characteristics of splenomegaly secondary to AP; (2) influencing factors for splenomegaly secondary to AP; (3) construction and evaluation of a nomogram prediction model for splenomegaly secondary to AP. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was analyzed using the rank sum test. Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. The univariate analysis was performed using statistical methods appropriate to the data type. The optimal cut-off value was determined by the receiver operating characteristic curves. Multivariate analysis was conducted using the Logistic regression model with forward method. Based on the results of the multivariate analysis, a nomogram prediction model was constructed. The receiver operating characteristic curve was drawn, and the discrimination was evaluated using the area under curve. The consistency of the nomogram prediction model was evaluated using calibration curve, and its clinical benefit was evaluated using decision curve. Results:(1) Occurrence and clinical characteristics of splenomegaly secondary to AP. The first detection time of 60 patients with splenomegaly secondary to AP was 60(30,120)days after the onset of AP. Cases with persistent respiratory dysfunction, multiple organ failure, severity of illness as mild or moderately severe/severe, pancreatic and/or peripancreatic infection, surgery were 19, 17, 4, 56, 37, 32 for 60 patients with splenomegaly secondary to AP, versus 16, 19, 43, 77, 39, 29 for 120 patients without splenomegaly secondary to AP, respectively, showing significant differences in the above indicators between the two groups ( χ2=8.58, 3.91, 17.64, 13.95, 15.19, P<0.05). (2) Influencing factors for splenomegaly secondary to AP. Resuts of multivariate analysis showed that white blood cell count <5.775×10?/L within 24 hours of AP onset, revised computed tomography (CT) severity index >7 in 3-7 days after onset and the presence of local complications were independent risk factors influencing the splenomegaly secondary to AP ( odds ratio=3.85, 2.86, 6.40, 95% confidence interval as 1.68-8.85, 1.18-6.95, 1.56-26.35, P<0.05). (4) Construction and evaluation of a nomogram prediction model for splenomegaly secondary to AP. The nomogram prediction model was constructed based on white blood cell count within 24 hours of AP onset, revised CT severity index in 3-7 days after onset and local complications. The area under the receiver operating characteristic curve of the nomogram prediction model was 0.76 (95% confidence interval as 0.69-0.83, P<0.05), with a sensitivity of 0.87 and a specificity of 0.55. The calibration curve demonstrated consistency between the predicted rate from the nomogram prediction model and the actually observed rate. The decision curve analysis indicated that the nomogram prediction model had favorable clinical practicability. Conclusions:Patients with AP who develop secondary splenomegaly tend to have a higher severity of illness than those develop no secondary splenomegaly. White blood cell count <5.775×10?/L within 24 hours of AP onset, revised CT severity index >7 in 3-7 days after onset and presence of local complications are independent risk factors influencing splenomegaly secondary to AP, and its nomogram prediction model can predict incidence rate of splenomegaly secondary to AP.

Hepatic encephalopathy is a clinical syndrome of central nervous system dysfunction caused by liver insufficiency.It severely affects the quality of life of patients and may lead to death.Accurate prediction of the risk of developing hepatic encephalopathy is crucial for early intervention and treatment.In order to identify the risk of hepatic encephalopathy in patients in advance,many studies have been devoted to efforts to develop tools and methods to identify the risk of hepatic encephalopathy as early as possible,so as to develop preventive and early management strategies.Most conventional hepatic encephalopathy risk prediction models currently assess the prob-ability of a patient developing hepatic encephalopathy by analysing factors such as clinical data and biochemical indicators,however,their accuracy,sensitivity and positive predictive value are not high.The application of artificial intelligence to clinical predictive modelling is a very hot and promising area,which can use large amounts of data and complex algorithms to improve the accuracy and efficiency of diagnosis and prognosis.To date,there have been few studies using AI techniques to predict hepatic encephalopathy.Therefore,this paper reviews the research progress of hepatic encephalopathy risk prediction models,and also discusses the prospect of AI application in hepatic encephalopathy risk prediction models.It also points out the challenges and future research directions of AI in HE risk prediction model research in order to promote the development and clinical application of hepatic encephalopathy risk prediction models.
