Objective To discuss the difference of handwriting characteristics of schizophrenia,neurosis and healthy people according to the gender,the age and the level of educated.Methods The handwriting data were obtained under the standard condition of handwriting,then the 24 Chinese characters handwriting image information were transformed into digital data using the quantitative characteristics of Chinese characters handwriting recognition system (CCQAS4.0),finally the data of 99 patients with schizophrenia and 131 patients with neurosis were analyzed.Results Many significant differences had been found in schizophrenia,neurosis and norm group (P ＜0.05,P＜0.01),such as footer space((198.33±26.50) mm,(180.31±39.31)mm,(192.39±35.08) mm),average line spacing ((4.02 ± 1.68) mm,(5.34 ± 2.20) mm,(4.76 ± 2.00) mm) etc ; and there were also some important differences between the schizophrenia patient and the neurosis patient from different gender,age and education level in the 24 handwriting characteristics (P＜0.05,P＜0.01).Conclusions (1) Significant handwriting characteristic differences have surely been found among the schizophrenia/neurosis patient and normal people.(2) Gender,age and education level have impact on the characteristic in the schizophrenia patient and the neurosis patient.

Objective:To analyze the influencing factors for depression in primary school children aged 9-10 years in Jiangsu Province, and to construct a risk prediction model.Methods:A retrospective study.A total of 1 162 primary school children aged 9-10 years from 3 primary schools in 3 regions of Jiangsu Province were recruited.Their demographic data were collected, and they were surveyed by the Depression Anxiety Stress Scales-21 (DASS-21), the Strengths and Difficulties Questionnaire (SDQ), and the Family Environment Scale (FES). Children were divided into control group (1 059 cases) and depression group (103 cases) based on the depression scores obtained from the DASS-21 scale.Multivariate Logistic regression analysis was used to analyze the influencing factors for depression in primary school students aged 9-10 and construct a risk prediction model. Results:There were significant differences in the economic development region, physical activities, academic performance, student cadres, parents′ education level, frequency of parental quarrels, SDQ and FES dimension scores between control group and depression group (all P<0.05). Among them, economic development areas (Northern Jiangsu and Southern Jiangsu), student cadres, father′s education level (elementary school and below) and intimacy of the FES scale were protective factors for depression in elementary school children; while emotional symptoms, peer problems and the total difficulty score in the SDQ scale, and the conflict in the FES scale were the risk factors for depression in elementary school children.The prediction model was created based on the influencing factors: Logit ( P)=-1.390×economic development area (Northern Jiangsu) -1.508×economic development area (Southern Jiangsu) -1.248×student cadres -2.206×father′s education level (primary school and below) -1.145×father′s education level (junior high school)+ 3.316×emotional symptoms in the SDQ+ 0.979×peer problems in the SDQ+ 2.520×total difficulty score in the SDQ -1.697×cohesion in the FES + 0.760×conflict in the FES -0.678.The area under the curve of receiver operating characteristic was 0.931, with the sensitivity and specificity of 85.42% and 91.83%, respectively. Conclusions:The regional level of economic development, class or school cadres, father′s education level, peer problems, total difficulty score, cohesion and conflict in the family are influencing factors for depression among primary school children aged 9-10 years in Jiangsu Province.The created prediction model can effectively assess the depressive risk factors in this population, which is conductive to achieve the early recognition and intervention of depression in them.

Objective To investigate gender differences of plasma glial cell line-derived neurotro-phic factor (GDNF) levels in patients with major depressive disorder (MDD). Methods MDD subjects (male 20,female 36) and healthy controls (HCs) (male 35,female 45) were divided into four groups by gender. Plasma levels of GDNF were measured and compared in different gender groups. The clinical symp-tom severity of MDD patients was evaluated by 17-item Hamilton Depression Scale (HAMD-17) and Hamil-ton Anxiety Scale (HAMA-17). Results (1)The plasma GDNF level in male patients with major depres-sive disorder (( 1. 55 ± 0. 43 ) pg/ml ) was significantly lower than that in healthy controls (( 1. 86 ± 0. 50)pg/ml,F=4. 64,P=0. 036). There was no significant difference in GDNF level between female de-pression patients((1.62±0.46)pg/ml)) and female healthy control((1. 64±0. 48)pg/ml,F=0. 18,P=0. 672). In HCs,the GDNF level of male was significantly higher than that of female((1. 86±0. 50)pg/ml, (1. 64±0. 48)pg/ml,F=2. 04,P=0. 045). There was no significant difference in GDNF level between male and female patients(P>0. 05). (2) GDNF level in male patients with major depressive disorder was nega-tively correlated with HAMA score(r=-0. 388,P=0. 034). Conclusion The expression of GDNF is affect-ed by sex factors,which may be related to the different pathogenesis of MDD.

Objective To investigate the changes in Th17 cells and CD4+CD25+regulatory T lym-phocytes ( Treg) as well as transcription factors and cytokines relating to them in children with Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (HLH) and to analyze their role and clinical significance. Methods Thirty-two children with newly diagnosed EBV-associated HLH in the Hematology/Oncology Department of Zhengzhou Children′s Hospital from January 2012 to December 2016 were enrolled in this study. Thirty healthy children taking physical examination in the same hospital in the corresponding period were recruited as controls. Percentages of Th17 and Treg cells in peripheral blood T lymphocytes were detected by flow cytometry. Expression of RORγt and Foxp3 at mRNA level in peripheral blood mononuclear cells was detected by real-time PCR. Levels of IL-6, IL-17, IL-10 and TGF-β1 in serum samples were measured by ELISA. Results Compared with the control group, the EBV-associated HLH group showed in-creased percentage of Th17 cells [(1. 09±0. 43)％ vs (0. 39±0. 19)％, P<0. 05] and enhanced expres-sion of RORγt at mRNA level [(1. 41±0. 37) vs (0. 67±0. 13), P<0. 05], but decreased percentage of Treg cells [(3. 66±1. 13)％ vs (6. 80±1. 15)％, P<0. 05] and inhibited expression of Foxp3 at mRNA level [(15. 97±5. 11) vs (30. 23±4. 95), P<0. 05]. All of the above mentioned changes were reversed af-ter treatment (P<0. 05). Serum levels of IL-6 and IL-17 of EBV-associated HLH group were higher than those of control group, while serum levels of IL-10 and TGF-β1 were lower (P<0. 05). Conclusion Im-balanced Th17/Treg cells might play an important role in the pathogenesis of EBV-associated HLH. Cyto-kines relating to the maintenance of Th17/Treg cell balance could be used as indicators of disease develop-ment.

Objective:To improve the understanding of autoimmune lymphoproliferative syndrome (ALPS).Methods:The clinical data of the proband and his family members in Children's Hospital Affiliated to Zhengzhou University in August 2018 were retrospectively analyzed, and the peripheral blood DNA of the proband, his parents and siblings was extracted. High-throughput next-generation sequencing was used to make gene analysis and validation. Phenotype and genotype of them were also analyzed. Relevant literature was reviewed.Results:The proband was a 1-year and 1-month old boy with hemolytic anemia, thrombocytopenia and splenomegaly as the main manifestations. The double negative T cells and the Vitamin B 12 of the proband were significantly increased and the autoantibodies were positive. The boy's father had a history of splenomegaly. His elder brother and sister had similar clinical manifestations. The results of next-generation sequencing showed that the FAS gene frameshift mutation (c.648delT) was detected in this boy and his father, elder brother and sister, which was a new mutation. After immunosuppressive treatment, the symptoms of the boy improved and the blood cells increased. Conclusions:The frameshift mutation of FAS gene may be the cause of the disease in this ALPS pedigree. Clinically, it is necessary to consider ALPS for children with unexplained hemocytopenia and hepatosplenomegaly. Double-negative T cells, autoantibodies, Vitamin B 12 should be tested, and high-throughput gene sequencing should be performed if necessary.

Objective:To explore the speech features of female patients with anhedonic depression and their recognition of pleasure deficient symptoms.Methods:A total of 102 female depression patients who were hospitalized at Nanjing Brain Hospital from September 2020 to October 2021 were selected, including 62 anhedonic depression patients (anhedonic group) and 40 non-anhedonic depression patients (non-anhedonic group). A total of 50 female healthy controls were recruited during the same period.All participants were evaluated by the 17-item Hamilton depression scale (HAMD-17), Snaith-Hamilton pleasure scale (SHAPS), and the temporal experience of pleasure scale (TEPS), as well as voice acquisition.SPSS 23.0 software was used for data processing.Statistical analysis was conducted using one-way ANOVA, non-parametric tests, Logistic regression, and receiver operating characteristic curve.Results:Compared with the non-anhedonic group, the anhedonic group showed significant changes in 15 voice features(all P<0.05), including Mel-frequency cepstral coefficients, formant frequencies, intensity, and energy features.Among these features, Mel-frequency cepstral coefficients exhibited the highest accuracy in identifying anhedonic depression, with sensitivity of 47.5%, specificity of 91.9%, area under curve (AUC) of 0.751, 95% CI=0.686-0.866.Formant frequencies could identify female anhedonic depression, with a sensitivity of 90.0%, a specificity of 40.3%, an AUC of 0.647, and 95% CI=0.605-0.824.Energy features could identify anhedonic deficient depression, with a sensitivity of 60.0%, a specificity of 74.2%, an AUC of 0.679, and 95% CI=0.587-0.804.Intensity features could identify female anhedonic depression, with a sensitivity of 70.0%, a specificity of 58.1%, an AUC of 0.640, and 95% CI=0.554-0.769. Conclusion:Mel-frequency cepstral coefficients, formant frequencies, intensity features, and energy features may have specific changes in female patients with anhedonic depression.The Mel-frequency cepstral coefficients has the highest recognition accuracy for anhedonic symptoms in female depression patients, and is expected to become an objective evaluation index for female anhedonic depression.

AIM:To investigate the effect of Tongsai granules(TSG)on epithelial barrier dysfunction in acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and the underlying mechanism.METHODS:Twenty-four Sprague-Dawley rats were randomly divided into control group,model group,TSG group,and moxifloxacin(MXF)+salbutamol(STL)group.Rat COPD model was established over 8 weeks.On day 3 of week 9,the rats with COPD were intratracheally administered Klebsiella pneumoniae to establish the AECOPD model.On days 1 to 2 and 4 to 7 in week 9,saline was administered via oral gavage to the rats in control and model groups,and the rats in TSG and MXF+ STL groups were treated daily with TSG and MXF+STL by gavage,respectively.Peak expiratory flow(PEF),histopatho-logical changes,and the expression levels of interleukin-1β(IL-1β),IL-6,tumor necrosis factor-α(TNF-α),matrix me-talloproteinase 2(MMP2),MMP9,zonula occludens-1(ZO-1),E-cadherin(E-Cad)and occludin(OCC)were deter-mined.Moreover,human bronchial epithelial BEAS-2B cells were exposed to cigarette smoke extract(CSE)and treated with different TSG fractions,and the protein levels of ZO-1,E-Cad,OCC,epidermal growth factor receptor(EGFR),phosphorylated EGFR(p-EGFR),extracellular signal-regulated kinase(ERK)and phosphorylated ERK(p-ERK)were determined.RESULTS:Treatment with TSG significantly reduced bronchial wall thickness,mean linear intercept,and the levels of IL-1β,IL-6,TNF-α,MMP2 and MMP9(P＜0.05 or P＜0.01),significantly increased mean alveolar number and PEF(P＜0.01),and up-regulated the ZO-1,E-Cad and OCC protein levels(P＜0.01)in the lungs of AECOPD rats.Treatment with TSG2,the second TSG fraction,increased the protein levels of ZO-1,E-Cad and OCC in a dose-dependent manner in CSE-exposed BEAS-2B cells(P＜0.05 or P＜0.01).Network pharmacology analysis of 328 targets of the com-pounds in TSG2 and 3 864 genes related to AECOPD suggested that TSG2 relieved AECOPD likely through the regulation of ERBB2,ERK,EGFR,IL and WNT signaling pathways.Treatment with TSG2 also inhibited CSE-induced increases in p-EGFR and p-ERK levels in BEAS-2B cells(P＜0.05 or P＜0.01).CONCLUSION:Treatment with TSG could maintain airway epithelial barrier function in AECOPD rats,likely through the inhibition of EGFR/ERK signaling pathway.

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 diagnosis and treatment of congenital leukemia and the main factors affecting its prognosis.Methods:Clinical data of children with congenital leukemia admitted to Zhengzhou Children′s Hospital from July 2007 to December 2017 were retrospectively collected.Their clinical characteristics, chemotherapy and factors affecting their long-term survival were analyzed.Results:A total of 23 cases of congenital leukemia were collected, who mostly complained of " increased white blood cells, skin nodules and skin hemorrhage" . Among them, 10 cases abandoned the treatment, who all died according to the follow-up results.Among the 13 treated cases, 7 cases were male, and 6 were female.One of the 13 cases was a twin.Eight cases were acute myeloid leukemia, and 5 cases were acute lymphoblastic leukemia.One case did not perform the fusion gene test. MLL gene was positive in 2 cases and negative in 10 cases.No other fusion genes were detected.Karyotype analysis showed that 1 case was 21-trisomy and 12 cases had a normal karyotype.All 13 patients received symptomatic and/or reduced chemotherapy.The median follow-up time was 4 years and 11 months.Six cases recovered and 7 cases died during the follow-up.One case was diagnosed with acute lymphoblastic leukemia on the 6 th day after the birth in another hospital.He was not treated timely and came to Zhengzhou Children′s Hospital with general contract blocks at the age of 32 days.After checking, he was diagnosed with center leukemia and testicular leukemia.He developed a severe infection in the lung and brain after strong chemotherapy, and died even after the remote consultation with Lurie Children′s Hospital of Chicago.The other 6 cases died of severe infection and multiple organ injuries after chemotherapy, and no one died of leukemia relapse. Conclusion:Reduction chemotherapy may be an important treatment to children with congenital leukemia.
