Objective:To develop the Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses and test its reliability and validity.Methods:Based on the theory of knowledge, attitude, and practice, the preliminary Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses was developed through literature search and analysis, Delphi expert consultation, and pre-survey. From February to April 2022, convenience sampling was used to select 375 surgical nurses from five Class Ⅲ Grade A hospitals and three Class Ⅲ Grade B hospitals in Zhejiang Province for questionnaire item analysis, exploratory factor analysis, and reliability testing.Results:The final Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses consisted of 33 items in three dimensions of knowledge, attitude, and practice. Exploratory factor analysis extracted three common factors with a cumulative variance contribution rate of 67.016%. The total Cronbach's α coefficient of the questionnaire was 0.931, and the Cronbach's α coefficients for each dimension were 0.972, 0.906, and 0.932, respectively. The overall test-retest reliability coefficient of the questionnaire was 0.999, and the test-retest reliability coefficients for each dimension were 0.997, 0.994, and 0.998. The questionnaire-level content validity index was 0.889, and the item-level content validity index was 0.833 to 1.000.Conclusions:The Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses has good reliability and validity, and can be used to evaluate the knowledge, attitude, and practice of postoperative subdelirium syndrome among surgical nurses.

ObjectiveTo explore the amelioration of cognitive dysfunction in diabetes mellitus （DM） by Jianpi Qinghua prescription （JPQH） based on type 2 diabetes （T2DM） model rats. MethodFifty healthy male Wistar rats of SPF grade were randomly divided into control group （n=10） and experimental group （n=40）. The rats in the control group were fed conventionally， while those in the experimental group were fed on a high-sugar， high-fat diet for six weeks and administered with streptozotocin （STZ） for the induction of the DM model. The model rats were randomly divided into model group， sitagliptin group （1.2 g·L^-1）， pioglitazone group （0.8 g·L^-1）， and JPQH group （1.3 g·mL^-1）， with 10 rats in each group. After six weeks of drug intervention， the changes in body weight， blood glucose， and other related indexes of each group were recorded. Enzyme-linked immunosorbent assay （ELISA） was performed to detect the levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） in the peripheral blood and brain. The Morris water maze test was used to evaluate the cognitive function in rats. Hematoxylin-eosin （HE） staining was used to observe the pathological morphology of the hippocampal CA region. The amyloid β-protein 40 （Aβ₄₀） level was detected by immunohistochemistry. The protein expression of t-tau and p-tau in hippocampal neurons of rats was detected by Western blot. ResultCompared with blank group， the body weight of model group was significantly decreased （P<0.05）， blood glucose level was significantly increased （P<0.01）， inflammatory cytokines TNF-α and IL-1β were increased （P<0.05）， learning and spatial ability were significantly decreased （P<0.01）， the arrangement of hippocampal cells was loose and disordered， and the intercellular space was significantly increased. The number of cells decreased significantly， and the expression of Aβ₄₀ increased significantly. and increased t-tau and p-tau protein content in the hippocampus （P<0.01）. Compared with model group， the JPQH group showed reduced blood glucose （P<0.01）， decreased TNF-α and IL-1β levels in the peripheral blood and cerebrospinal fluid （P<0.05）， a downward trend of IL-6 without a statistical difference， improved learning and spatial memory ability （P<0.01）， densely arranged cells in the hippocampal CA1 area， increased cell number， reduced Aβ₄₀ expression， and decreased p-tau protein expression （P<0.05）. ConclusionJPQH can prevent cognitive dysfunction in DM by reducing inflammatory factor levels， decreasing neurotoxicity caused by Aβ₄₀ deposition， and inhibiting hyperphosphorylation of tau protein in DM rats.

Abstract: Cell death is a fundamental biological phenomenon that is essential for the survival and development of organisms. Cell death can be either a spontaneous programmed process by the host or an accidentally triggered process. According to the different signaling pathway activated by various stimulates, programmed cell death exhibits the lytic or non-lytic morphology. For example, apoptosis, a typical non-lytic form of cell death, exhibits cell shrinkage and induces the formation of apoptotic bodies. Pyroptosis mediated by cysteine-containing aspartate-specific protease-1/11 (caspase-1/11) and necroptosis can induce inflammatory reactions and promote cell lysis to release inflammatory cytokines via triggering the pore-forming mechanism of the cell membrane, representing a typical modes of lytic cell death. In addition, the release of reactive oxygen species caused by the damaged mitochondria may further trigger ferroptosis during the pathogen infection. Programmed cell death can play an immune defensive role by eliminating infected cells and intracellular pathogens and stimulating the innate immune response through the resulting cell corpses. Here, we discuss the molecular mechanisms of five programmed cell death pathways: apoptosis, pyroptosis, ferroptosis, necroptosis and PANoptosis. We describe their roles in the innate immune defense against bacterial infections and give a brief statement of the interactions between the different programmed cell death, hoping to provide new insights for in-depth study of the pathogenic mechanisms of infectious diseases.

Objective:To investigate the clinical characteristics and gene mutations of subcutaneous panniculitis-like T-cell lymphoma (SPTCL) secondary to familial hemophagocytic syndrome (FHL).Methods:The clinical features, disease evolution, gene mutation and genetic characteristics of 1 SPTCL patient secondary to FHL in Henan Children's Hospital in June 2012 were analyzed retrospectively, and the related literatures were reviewed.Results:The UNC13D of FHL patient was homozygous mutation accompanied by STXBP2 heterozygous mutation, while that of his parents and elder brother was heterozygous mutation. After regular chemotherapy with HLH-2004 regimen, the disease relapsed 4 years later, and secondary SPTCL developed after 1 year of remission with the second chemotherapy. After giving SMILE regimen chemotherapy, allogeneic hematopoietic stem cell transplantation was performed, and now the patient had disease-free survival.Conclusions:The detection of related genes in children with hemophagocytic syndrome should be improved in time to confirm the diagnosis of primary disease. FHL can follow SPTCL, and chemotherapy combined with allogeneic hematopoietic stem cell transplantation can be the only method to cure this disease.

Objective:To investigate the effects of gestational diabetes mellitus (GDM) on neonatal metabolites.Methods:This retrospective cohort study recruited 580 singleton newborns who were born to women with GDM from January 2018 to December 2018 in Foshan Maternal and Child Health Care Hospital as the GDM group. Another 580 counterparts born to non-GDM singleton mothers with matching age were selected as the non-GDM group with an allocation ratio of 1 to 1. Neonatal genetic metabolic disease screening was performed within 3-7 days after birth. Two independent sample t-test, and multiple linear regression model were used for statistical analysis. Results:There were significant differences in seven amino acids and 10 fatty acids levels between the GDM and non-GDM group. The serum levels of six amino acids and eight fatty acids were increased in the GDM group, while the levels of piperamide [(140.79±32.60) vs (150.26±35.46) μmol/L, t=－4.733, P<0.001], palmitoyl carnitine [(2.59±0.81) vs (2.73±0.82) μmol/L, t=－2.940, P=0.003], and carbamate [(0.066±0.022) vs (0.069±0.022) μmol/L, t=－1.937, P=0.042] were decreased compared with the non-GDM group. After adjusting for maternal gravidity, parity, neonatal birth weight, and gender, multivariate linear regression analysis showed that GDM was positively correlated with three amino acids levels, which were cysteine ( ?=0.012), homocysteine ( ?=0.263) and leucine ( ?=4.225); and was negatively correlated with glycine ( ?=－6.271) and piperamide level ( ?=－9.885). With regard to the fatty acids, GDM was positively correlated with the neonatal propionyl carnitine ( ?=0.214), butyryl carnitine ( ?=0.014), 3-hydroxybutyryl carnitine ( ?=0.006), isovaleryl carnitine ( ?=0.009), 3-hydroxyisovaleryl carnitine ( ?=0.024), hexadecanoyl carnitine ( ?=0.001), decadienoyl carnitine ( ?=0.045), octadecadienyl carnitine level ( ?=0.128), but was negatively correlated with palmitoyl carnitine ( ?=－0.119), and carbamate ( ?=－0.002) (all P<0.05). Conclusions:Correlations between maternal GDM and the levels of amino acids and fatty acids in neonates was noted in this study, suggesting that maternal GDM may affect the metabolism of amino acids and fatty acids in offspring at early stage of life.

OBJECTIVE: To investigate the optimal dose range of immunosuppressants in patients with autosomal dominant polycystic kidney disease (ADPKD) after renal transplantation. METHODS: A cohort of 68 patients with ADPKD who received their first renal transplantation between March, 2000 and January, 2018 in our institute were retrospectively analyzed, with 68 non-ADPKD renal transplant recipients matched for gender, age and date of transplant as the control group. We analyzed the differences in patient and renal survival rates, postoperative complications and concentrations of immunosuppressive agents between the two groups at different time points within 1 year after kidney transplantation. The concentrations of the immunosuppressants were also compared between the ADPKD patients with urinary tract infections (UTI) and those without UTI after the transplantation. RESULTS: The recipients with ADPKD and the control recipients showed no significantly difference in the overall 1-, 5-, and 10- year patient survival rates (96.6% 96.0%, 94.1% 93.9%, and 90.6% 93.9%, respectively; > 0.05), 1-, 5-, and 10-year graft survival rates (95.2% 96.0%, 90.8% 87.2%, and 79.0% 82.3%, respectively; > 0.05), or the incidences of other post- transplant complications including acute rejection, gastrointestinal symptoms, cardiovascular events, pneumonia, and neoplasms ( > 0.05). The plasma concentrations of both tacrolimus and mycophenolate mofetil (MPA) in ADPKD group were significantly lower than those in the control group at 9 months after operation ( < 0.05). The incidence of UTI was significantly higher in ADPKD patients than in the control group ( < 0.05). In patients with ADPKD, those with UTI after transplantation had a significantly higher MPA plasma concentration ( < 0.05). CONCLUSIONS In patients with ADPKD after renal transplant, a higher dose of MPA is associated with a increased risk of UTI, and their plasma concentrations of immunosuppressants for long-term maintenance of immunosuppression regimen can be lower than those in other kidney transplantation recipients.

Purpose: Progressive familial intrahepatic cholestasis (PFIC) is a rare genetic autosomal recessive disease caused by mutations in ATP8B1, ABCB11 or ABCB4. Mutational analysis of these genes is a reliable approach to identify the disorder. Methods: We collected and analyzed relevant data related to clinical diagnosis, biological investigation, and molecular determination in nine children carrying these gene mutations, who were from unrelated families in South China. Results: Of the nine patients (five males, four females) with PFIC, one case of PFIC1, four cases of PFIC2, and four cases of PFIC3 were diagnosed. Except in patient no. 8, jaundice and severe pruritus were the major clinical signs in all forms. γ-glutamyl transpeptidase was low in patients with PFIC1/PFIC2, and remained mildly elevated in patients with PFIC3. We identified 15 different mutations, including nine novel mutations (p.R470HfsX8, p.Q794X and p.I1170T of ABCB11 gene mutations, p.G319R, p.A1047P, p.G1074R, p.T830NfsX11, p.A1047PfsX8 and p.N1048TfsX of ABCB4 gene mutations) and six known mutations (p.G446R and p.F529del of ATP8B1 gene mutations, p.A588V, p.G1004D and p.R1057X of ABCB11 gene mutations, p.P479L of ABCB4 gene mutations). The results showed that compared with other regions, these three types of PFIC genes had different mutational spectrum in China. Conclusion The study expands the genotypic spectrum of PFIC. We identified nine novel mutations of PFIC and our findings could help in the diagnosis and treatment of this disease.

Objective To provide theoretic rationales and clinical experience for post-transplant lymphoproliferative disorder (PTLD ) by comparing the characteristics of PTLD in kidney and hematopoietic stem cell transplant recipients and reviewing the relevant literature reports .Methods Twenty-seven adult PTLD patients from 2000 to 2017 were retrospectively reviewed .There were 11 kidney transplant recipients (KT group) and 16 hematopoietic stem cell transplant recipients (HSCT group) .Clinical characteristics and outcomes were analyzed between two groups .Cox's proportional hazard model was utilized for evaluating the prognostic factors .Results The incidence of PTLD for KT and HSCT groups were 0 .5 ％ and 1 .1 ％ respectively .PTLD patients of KT group had a later onset than that of HSCT group (105 .1 vs 3 .1 months , P<0 .01) .Also Epstein-Barr virus was less frequently detected in KT group (36 .4 ％ vs 81 .3 ％ , P< 0 .05) .The 5-year overall survival was (46 .8％ ± 10 .5％ ) .According to Cox analysis ,application of antithymocyte globulin (ATG) and high ECOG scores were risk factors for a poor prognosis of PTLD .Conclusions Most cases of KT-PTLD have a late onset . In contrast , HSCT-PTLD has an earlier onset and a higher incidence of EBV infectious .And application of ATG and high ECOG scores are poor prognosis factors of PTLD .
