ObjectiveTo observe the prognosis effect of soluble programmed death ligand-1（sPD-L1） in treating patients with advanced lung adenocarcinoma treated with epidermal growth factor receptor-tyrosine kinase inhibitors（EGFR-TKIs） and the influence of Yiqi Yangyin Jiedu prescription. MethodA prospective cohort-controlled study was conducted to enroll patients treated with EGFR-TKIs in the first line of treatment，who were admitted to the Oncology Department of Longhua Hospital and Shanghai Chest Hospital from May 1^st， 2021 to June 30^th， 2023， and they were evaluated as non-progressive and identified with deficiency of Qi and Yin after one month of treatment. The patients were divided into an exposed group （EGFR-TKIs combined with Yiqi Yangyin Jiedu prescription） and a non-exposed group （EGFR-TKIs alone）according to whether or not they were treated with Yiqi Yangyin Jiedu prescription and were treated until disease progression， or death and intolerable adverse reactions occurred. The enzyme-linked immunosorbent assay （ELISA） was applied to detect the level of sPD-L1 in patients at the time of enrollment and disease progression，and Cox risk proportionality model was used to analyze the independent prognostic factors affecting disease progression of patients treated with EGFR-TKIs. ResultA total of 90 patients （39 in the exposed group and 51 in the non-exposed group） undergoing disease progression after EGFR-TKI treatment were enrolled. At the time of enrolment and after disease progression，the levels of serum sPD-L1 in the 90 patients were 12.06 （27.54） ng·L^-1 and 41.99 （62.93） ng·L^-1，respectively. Compared with that at the time of enrollment， the serum sPD-L1 level in the 90 patients was significantly increased after disease progression （P<0.01）. The serum sPD-L1 level in patients in the exposed group was 12.27 （24.78） ng·L^-1 and 29.57 （61.12）ng·L^-1 respectively at the time of enrolment and after disease progression. In the non-exposed group， patients had serum sPD-L1 levels of 11.81 （28.46） ng·L^-1 and 49.54 （74.12） ng·L^-1 respectively at the time of enrolment and after disease progression. Compared with that at the time of enrollment， the serum sPD-L1 level in the two groups of patients was significantly increased after disease progression （P<0.01）. In addition， compared with that in the non-exposed group， the sPD-L1 level in the exposed group was greatly reduced after disease progression（P<0.01）. Cox multifactorial analysis showed that sPD-L1 level and age at the time of enrolment were associated with patients' progression-free survival（PFS），and that low levels of sPD-L1 （<12.06 ng·L^-1） prolonged the PFS and reduced the risk of disease progression in patients treated with EGFR-TKIs compared with high levels of sPD-L1. ConclusionElevated sPD-L1 level is a poor prognostic factor for the long-term efficacy of EGFR-TKIs，and treatment with Yiqi Yangiin Jiedu prescription can down-regulate sPD-L1 level of patients treated with EGFR-TKIs.

Under the background of the Healthy China strategy， the integration of traditional Chinese medicine （TCM） into the public health emergency response system has become an important measure to enhance the capacity for coping with public health emergencies. In recent years， the role of TCM in responding to such emergencies has become increasingly prominent. Taking major emerging epidemics as an example， TCM has developed a rich theoretical system and practical experience in epidemic prevention and treatment over thousands of years， and has played a significant role in successive outbreaks with its unique advantages. Based on the concept of ''preventing disease before its onset'' and the theoretical framework of treatment based on syndrome differentiation， TCM has achieved remarkable results through early intervention and full participation in the integrated model of TCM and Western medicine， from severe acute respiratory syndrome （SARS） to corona virus disease-2019 （COVID-19）， in improving clinical symptoms and outcomes， reducing adverse reactions， and promoting recovery. From the perspective of the Healthy China strategy， this paper systematically reviews the historical development of TCM in epidemic prevention and treatment， with particular attention to recent epidemics such as SARS， influenza A （H1N1）， and COVID-19. It further examines the similarities and differences between TCM and Western medicine in responding to major emerging epidemics， as well as relevant policies related to TCM in epidemic prevention and control. In addition， it summarizes the existing problems in TCM's role in the prevention and treatment of major emerging epidemics， and explores measures to improve its rapid response capacity under the Healthy China strategy. This study not only provides a ''Chinese solution'' for the prevention and control of newly emerging infectious diseases worldwide， but also offers theoretical and practical references for strengthening the public health emergency response system， carrying strategic significance for promoting the modernization and internationalization of TCM.

Objective:To explore the risk factors of bortezomib-related peripheral neuropathy (BIPN) and the clinical and electrophysiological characteristics of patients in treatment of multiple myeloma (MM).Methods:The clinical data of 71 newly diagnosed MM patients treated with BD (bortezomib + dexamethasone) regimen in Yancheng First People's Hospital from March 2016 to December 2019 were retrospectively analyzed. The bone marrow morphology, immunology, cytogenetics, molecular biology (MICM), routine electrophysiological examination before and after treatment were performed. All patients were divided into the peripheral neuropathy (PN) group and the non-PN group according to the presence or not of BIPN, and the clinicopathological differences of both groups were also compared; a binary logistic regression model was used to analyze the factors affecting the occurrence of PN. The electrophysiological characteristics were summarized and fluorescence in situ hybridization (FISH) was used to detect karyotype of BIPN patients.Results:Among 71 MM patients, there were 40 cases (56.3%) of PN and 31 cases (43.7%) of non-PN. The proportion of patients at international staging system (ISS) staging Ⅲ, and the levels of IgA, IgG, IgM, serum creatinine, β 2-microglobulin (β 2-MG) in the PN group were higher than those in the non-PN group, and hemoglobin (Hb) level in the PN group was lower than that in the non-PN group, and the differences were statistically significant (both P < 0.05). Binary logistic regression analysis showed that increased IgA ( OR = 1.151, 95% CI 1.012-1.309, P = 0.033), increased IgG ( OR = 1.055, 95% CI 1.000~1.112, P = 0.049), increased IgM ( OR = 1.010, 95% CI 1.001-1.018, P = 0.022), increased serum creatinine ( OR = 1.037, 95% CI 1.011~1.065, P = 0.005), increased β 2-MG ( OR = 1.564, 95% CI 1.039-2.354, P = 0.032) were risk factors for BIPN. Among 40 patients with BIPN, 33 cases (82.5%) of sensory nerve conduction velocity (SCV) were abnormal, 23 cases (57.5%) of motor nerve conduction velocity (MCV) were abnormal; 31 cases (77.5%) showed demyelination damage, 9 cases (22.5%) had axonal damage. Among 40 patients with BIPN, 24 cases underwent FISH detection, including 19 cases (79.2%) with chromosomal mutations, of which 12 cases (50.0%) were mixed subtype abnormal. Conclusions:MM patients with high levels of β 2-MG, IgA, IgG, IgM and serum creatinine are more prone to PN when treated with bortezomib. The electrophysiology of patients with BIPN is mainly characterized by demyelination of sensory nerves.

OBJECTIVE: To explore the clinical feature and genetic etiology of a patient with normosmic idiopathic hypogonadotropic hypogonadism (nIHH) due to variant of CHD7 gene. METHODS: A patient who had presented at Anhui Provincial Children's Hospital in October 2022 was selected as the study subject. Clinical data of the patient was collected. The patient and his parents were subjected to trio-whole exome sequencing. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The patient had featured delayed development of secondary sexual characteristics but normal olfactory function. Genetic testing revealed that he has harbored a c.3052C>T (p.Pro1018Ser) missense variant of the CHD7 gene, for which both of his parents were of the wild type. The variant has not been recorded in the PubMed and HGMD databases. Analysis of amino acid sequences suggested that the variant site is highly conserved, and the variant may affect the stability of protein structure. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.3032C>T variant was classified as a likely pathogenic (PS2+PM2_Supporting+PP2+PP3+PP4). CONCLUSION The delayed development of secondary sexual characteristics of the patient may be attributed to the c.3052C>T (p.Pro1018Ser) variant of the CHD7 gene. Above finding has expanded the variation spectrum of the CHD7 gene.

Objective:To construct a biospecimen bank of patient derived organoids (PDOs) from pancreatic cancer tissues and to explore the feasibility of PDOs drug sensitivity assay technology to guide chemotherapy drug selection for pancreatic cancer.Methods:Pancreatic cancer tissue specimens obtained after surgical resection and puncture biopsy from Mar 2020 to Dec 2022 at Drum Tower Hospital, Nanjing University School of Medicine were collected. Pancreatic cancer PDOs were cultured in vitro and histologically identified; PDOs were treated with gemcitabine, Nab-paclitaxel, fluorouracil, Oxaliplatin, and Irinotecan and cell viability was measured to analyze the correlation between PDOs drug sensitivity and the actual clinical treatment response.Results:The PDOs can reproduce the pathological features of corresponding tumor tissues; the sensitivity of different PDOs to the same chemotherapeutic drug is significantly different; The sensitivity of PDOs was highly consistent with the actual treatment effect of the corresponding patients 75.76% (25/33); organoid organ-based susceptibility testing had predictive value for the treatment response of patients (AUC=0.733, 95% CI: 0.546-0.919, P<0.05). Conclusion:A biobank of pancreatic cancer PDOs was successfully constructed, and the drug susceptibility test results were significantly correlated with the actual medication response of patients, suggesting that the drug susceptibility test technology based on PDOs has the potential to guide individualized chemotherapy for pancreatic cancer.

Objective:To investigate the role of miR-146a in the pathogenesis of systemic juvenile idiopathic arthritis (sJIA) and its clinical significance.Methods:This article is a prospective clinical cohort study.Twenty-six patients with sJIA (14 cases of initial active group and 12 cases of stable group), 15 patients with multijoint juvenile idiopathic arthritis (JIA) and 15 patients with oligojoint JIA diagnosed in the Department of Rheumatology and Immunology of Anhui Provincial Children′s Hospital from June 2018 to December 2020 were enrolled.Twenty healthy controls from the out-patient clinic were also recruited.The expression level of miR-146a in peripheral blood mononuclear cells (PBMCs) of research objects was detected by real-time fluorescence quantitative polymerase reaction (qPCR), and the serum levels of interleukin (IL) - 6, tumor necrosis factor (TNF) - α and IL-1β in sJIA patients and healthy controls were detected by enzyme-linked immunosorbent assay.The expression levels of miR-146a in PBMCs and cytokines among different groups were compared by analysis of variance. Pearson correlation analysis was used to analyze the correlation of the relative expression level of miR-146a in PBMCs with clinical inflammatory indexes and serum cytokines in sJIA patients. Results:(1) The expression level of miR-146a in PBMCs of early sJIA patients was significantly higher than that in the multijoint JIA group and oligojoint JIA group (8.77±3.15 vs.4.40±1.59, 2.55±1.15, t=6.27, 14.23; all P<0.05). The expression level of miR-146a in PBMCs of sJIA active patients was significantly higher than that in sJIA stable patients (8.77±3.15 vs.3.63±1.37, t=10.27, P<0.05). There was no significant difference in the expression level of miR-146a between the sJIA stable group and healthy control group ( P>0.05). (2) The expression levels of IL-1β, IL-6 and TNF-α were significantly higher in sJIA active patients group than those in sJIA stable group[(58.56±17.47) ng/L vs.(26.32±10.54) ng/L, (73.72±11.16) ng/L vs.(23.20±9.12) ng/L, (70.93±19.97) ng/L vs.(24.25±9.49) ng/L, all P<0.05]. There was no significant difference in the expression levels of IL-1β, IL-6 and TNF-α between the sJIA stable group and healthy control group(all P>0.05). (3)The expression of miR-146a in PBMCs of sJIA patients was positively correlated with serum ferritin levels, platelets, erythrocyte sedimentation rates, C-reactive proteins, IL-1β, IL-6 and TNF-α( r=0.542, 0.433, 0.329, 0.306, 0.333, 0.342, 0.319, all P<0.05). Conclusions:miR-146a may be involved in the inflammatory process of sJIA disease.miR-146a can well distinguish sJIA from multijoint JIA and oligojoint JIA.TNF-α, IL-1β and IL-6 are involved in sJIA inflammatory responses.

Objective:To investigate the familial inheritances, clinical features, treatments and outcomes of familial Waldenstrom macroglobulinemia (WM) patients.Methods:The clinical manifestations, laboratory examinations, diagnosis and treatments, and follow-up data of 6 familial WM patients who were admitted to Yancheng No.1 People's Hospital from June 2002 to July 2019 were retrospectively analyzed, and the literature was reviewed.Results:Among 6 WM patients, 4 patients had dizziness and fatigue at the onset, 1 patient had recurrent low-grade fever and abnormal sweating as the first manifestations, 1 patient was hospitalized due to pulmonary infection, and WM was found later. Two brothers of the patients were diagnosed with WM, another 2 brothers of the patients had IgM-type monoclonal gammopathy of undetermined significance (MGUS) during the physical examination. All the 6 patients were middle-aged/elderly men, with a median age of 63 years old (51-70 years old). The median follow-up time were 71.5 months (4-217 months), and by the end of the follow-up (June 2020), 2 cases died of pulmonary infection, and 1 of them developed acute myeloid leukemia; the other 4 cases were in regular chemotherapy. Two IgM-MGUS patients were followed up without symptoms.Conclusions:WM patients have familial aggregation, and their clinical manifestations are highly heterogeneous. Patients with family history may have poor prognosis. It is necessary to strengthen the awareness of WM and family history screening.

OBJECTIVE: To investigate the clinical characteristics and genetic basis for a child with Keppen-Lubinsky syndrome (KPLBS). METHODS: Trio-whole exome sequencing (Trio-WES) was carried out for the proband and her parents. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The child has featured peculiar facies including large eyes, alar hypoplasia, microretrognathia, premature aging appearance in addition with growth delay and mental retardation. Trio-WES has identified that she has carried a de novo variant of the KCNJ6 gene, namely c.460G>C (p.Gly154Arg). The variant has not been recorded in the database. Prediction of protein structure indicated that the variant may affect the potassium ion selective filtration structure channel in the transmembrane region of KCNJ6 protein, which may result in up regulation of the function of the channel. CONCLUSION The de novo c.460G>C (p.Gly154Arg) variant of the KCNJ6 gene probably underlay the KPLBS in this child. Above finding has enriched the genotypic and phenotype spectrum of this syndrome.

Objective:To investigate the expression of Toll-like receptor 8 (TLR8) in diffuse large B-cell lymphoma (DLBCL) and its correlation with clinicopathological characteristics and prognosis of patients.Methods:The data in the Oncomine database was used to analyze the difference of TLR8 mRNA expression between DLBCL tumor tissues and normal lymphocytes, and the result was verified in two independent subsets GSE 25638 and GSE 32018 of the NCBI-GEO database. The OSDLBCL online survival analysis tool was used to analyze the correlation of TLR8 mRNA relative expression level with overall survival (OS) and progression-free survival (PFS) of DLBCL patients. Gene ontology bioprocess (GO_BP) enrichment analysis was performed by using GSEA software. The correlation of TLR8 mRNA expression with tumor immune cell infiltration degree and immune checkpoint-related molecule expression was analyzed by TIMER online tool website. A total of 53 DLBCL patients who underwent lymph node biopsy in Yancheng No. 1 People's Hospital from June 2020 to June 2021 were selected. Immunohistochemistry was used to detect the expression of TLR8 protein, and its relationship with the clinicopathological characteristics of patients was analyzed.Results:The analysis result of data from Oncomine and GEO databases showed that the relative expression levels of TLR8 mRNA in tumor tissues of patients with DLBCL or activated B cell-like DLCBL were higher than those in normal lymphocytes (all P < 0.001). The results of OSDLBCL online survival analysis indicated that the OS ( P = 0.020) and PFS ( P = 0.004) in DLBCL patients with high TLR8 mRNA expression were worse than those in patients with low TLR8 mRNA expression. The level of TLR8 was related to the abnormal function of immune response, cytokine metabolism and DNA damage monitoring; the result of TIMER online analysis showed that the expression level of TLR8 mRNA was positively related to the degree of neutrophil infiltration ( r = 0.78, P < 0.001) and the expression of immunosuppressive molecules [HAVCR2 ( r = 0.85, P < 0.001), LAG3 ( r = 0.63, P < 0.001), CD274 ( r = 0.77, P < 0.001), TIGIT ( r = 0.32, P = 0.037), and C10ORF54 ( r = 0.34, P = 0.029)]. Among 53 DLBCL patients, 29 patients (54.7%) had low expression of TLR8 protein and 24 patients (45.3%) had high expression of TLR8 protein. There were statistical differences in the expressions of TLR8 protein in DLBCL patients with different serum lactate dehydrogenase and β 2-microglobulin levels (both P < 0.05). Conclusions:TLR8 is highly expressed in DLBCL patients, and TLR8 may be a prognostic marker of DLBCL.
