Objective To investigate the effect of parent-child alienation on depression in surface ship officers and soldiers based on the theory of"diathesis-stress",and the mediating role of resilience between parent-child alienation and depression in them.Methods A cross-sectional study was conducted on 599 officers and soldiers from a surface ship unit.The participants were surveyed with inventory of alienation toward parents,connor-davidson resilience scale and patient health questionnaire-9 to obtain and analyze their demographic-military characteristics of their depression scores.The participants with depression scores ≥5 were recruited as the subjects,and Spearman correlation analysis was used to explore the correlation among parent-child alienation,resilience and depression.On the basis of hierarchical regression analysis,AMOS software was used to establish a structural equation modelling of intermediary effects.Results The depression score was 1(0,4)in the participants,and the depression scores of those with service length ≥11 years were comparatively higher than those with shorter length.Our results indicated that parent-child alienation was positive correlated with depression(r=0.451,P＜0.001),while resilience was negatively correlated with depression and parent-child alienation(r=-0.412,-0.407,P＜0.001).Regression analysis revealed that parent-child alienation had a direct positive predictive value for depression(β=0.574,P＜0.001),and resilience showed a negative predictive value for depression(β=-0.211,P＜0.01).Model analysis displayed that resilience had a significant mediating role in the effect of parent-child alienation on depression among these surface ship officers and soldiers,with an effect value of 0.088,and accounting for 15.86％of the total effect.Conclusion Parent-child alienation has a significant influence on depression among surface ship officers and soldiers,with resilience playing a partial mediating role.

Objective:To summarize the clinical and genetic characteristics of early-onset spinocerebellar ataxia type 5 (SCA5) caused by SPTBN2 gene mutation. Methods:The clinical and genetic data of a child with early-onset SCA5 diagnosed in the Department of Children′s Rehabilitation, Women and Children′s Hospital Affiliated to Qingdao University in February 2022 were retrospectively analyzed. The literatures related to early-onset SCA5 in major databases at home and abroad were retrieved and summarized.Results:The patient, a 4 years and 1 month old girl, was admitted to hospital because of "unable to stand independently at 2 years and 3 months", primarily presented with developmental delay, ataxia, hypotonia, and tendon hyperreflexia during infancy. Progressive cerebellar atrophy was observed on brain magnetic resonance imaging. A de novo heterozygous mutation of the SPTBN2 c.793G>C(p.Asp265His) was identified in the patient. Following hospitalization, the child received comprehensive rehabilitation therapy encompassing physical, occupational, language, educational interventions as well as bicycle ergometer training and transcranial magnetic stimulation. The patient was followed-up for more than 1 year to 4 years and 1 month old, whose motor function, cognitive abilities, and language skills were improved to some extent. A total of 13 English articles and 1 Chinese article were retrieved from the databases. A total of 20 early-onset SCA5 patients have been reported, with onset ages all within 12 months. Infants exhibited decreased muscle tone and delayed motor milestones, with the main clinical manifestations of ataxia, generalized developmental delay, and cerebellar atrophy. The previously reported cases involved 11 mutation sites in the SPTBN2 gene, and the main types of mutations were de novo missense mutations. The mutation site in this case has not been reported in the previous literature. Conclusions:Early-onset SCA5 is a rare autosomal dominant disorder caused by heterozygous mutations in the SPTBN2 gene. The main clinical manifestations include ataxia from infancy, developmental retardation and cerebellar atrophy. Early rehabilitation intervention can improve the degree of the dysfunction.

OBJECTIVE: To analyze the characteristics of gene mutation and overexpression in newly diagnosed multiple myeloma (NDMM) patients. METHODS: Bone marrow cells from 208 NDMM patients were collected and analyzed. The gene mutation of 28 genes and overexpression of 6 genes was detected by DNA sequencing. Chromosome structure abnormalities were detected by fluorescence in situ hybridization (FISH). RESULTS: Gene mutations were detected in 61 (29.33%) NDMM patients. Some mutations occurred in 5 or more cases, such as NRAS, PRDM1, FAM46C, MYC, CCND1, LTB, DIS3, KRAS, and CRBN. Overexpression of six genes (CCND1, CCND3, BCL-2, CCND2, FGFR3, and MYC) were detected in 83 (39.9%) patients, and cell cycle regulation gene was the most common. Single nucleotide polymorphisms (SNP) changes were detected in 169 (81.25%) patients, the TP53 P72R gene SNP (70.17%) was the most common. Abnormality in chromosome structure was correlated to gene overexpression. Compared to the patients with normal chromosome structure, patients with 14q32 deletion showed higher proportion of CCND1 overexpression. Similarly, patients with 13q14 deletion showed higher proportion of FGFR3 overexpression, whereas patients with 1q21 amplification showed higher proportion of CCND2, BCL-2 and FGFR3 overexpression. CONCLUSION There are multiple gene mutations and overexpression in NDMM. However, there is no dominated single mutation or overexpression of genes. The most common gene mutations are those in the RAS/MAPK pathway and the genes of cyclin family CCND are overexpression.

OBJECTIVE: To compare the clinical effect on intestinal dysfunction of spinal cord injury (SCI) between the comprehensive therapy of moxibustion (moxibustion for opening the governor vessel and regulating the spirit) and rehabilitation training and the simple treatment with rehabilitation training. METHODS: A total of 60 patients with intestinal dysfunction of SCI were randomized into a comprehensive therapy group and a rehabilitation group, 30 cases in each one (3 cases were dropped out in each group). On the base of the routine western medicine treatment and rehabilitation training, the bowel training and rectal function training were provided, once a day in the rehabilitation group. In the comprehensive therapy group, on the base of the treatment as the rehabilitation group, the moxibustion was exerted at Yaoyangguan (GV 3), Mingmen (GV 4), Zhiyang (GV 9), Dazhui (GV 14) and Baihui (GV 20), etc, once a day, 30 min each time. In both groups, the treatment for 4 weeks was as one course and 3 courses of treatment were required. Separately, before treatment, after 4, 8 and 12 weeks of treatment, the scores of neurogenic bowel dysfunction (NBD) and World Health Organization quality of life scale (WHOQOL-BREF) were observed and the clinical effect was evaluated after 12 weeks of treatment. RESULTS: After treatment, the total effective rate was 88.9% (24/27) in the comprehensive therapy group, which was higher than 74.1% (20/27) in the rehabilitation group (<0.05). After 4, 8 and 12 weeks of treatment, NBD scores were all reduced obviously as compared with those before treatment in the two groups (all <0.01). After 8 and 12 weeks of treatment, NBD scores in the comprehensive therapy group were lower than the rehabilitation group (both <0.05). After 4, 8 and 12 weeks of treatment, the scores of all of the domains (psychology, physiology, social relations and environment) in WHOQOL-BREF were higher than those before treatment in the two groups (all <0.01). After 4 weeks of treatment, the scores in the psychology and physiology domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05). After 8 and 12 weeks of treatment, the scores of all of the domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05). CONCLUSION The comprehensive treatment of moxibustion and rehabilitation training achieves the better effect on intestinal dysfunction of SCI than the simple rehabilitation training and greatly improves the quality of life in SCI patients.

BACKGROUND: Gestational diabetes mellitus (GDM) is usually diagnosed between 24th and 28th gestational week using the 75-g oral glucose tolerance test (OGTT). It is difficult to predict GDM before 24th gestational week because fast plasma glucose (FPG) decreases as the gestational age increases. It is controversial that if FPG ≥5.1 mmol/L before 24th gestational week should be intervened or not. The aim of this study was to evaluate the value of FPG to screen GDM before 24th gestational week in women with different pre-pregnancy body mass index (BMI). METHODS: This was a multi-region retrospective cohort study in China. Women who had a singleton live birth between June 20, 2013 and November 30, 2014, resided in Beijing, Guangzhou and Chengdu, and received prenatal care in 21 selected hospitals, were included in this study. Pre-pregnancy BMI, FPG before the 24th gestational week, and one-step GDM screening with 75 g-OGTT at the 24th to 28th gestational weeks were extracted from medical charts and analyzed. The pregnant women were classified into four groups based on pre-pregnancy BMI: Group A (underweight, BMI < 18.5 kg/m), Group B (normal, BMI 18.5-23.9 kg/m), Group C (overweight, BMI 24.0-27.9 kg/m) and Group D (obesity, BMI ≥28.0 kg/m). The trend of FPG before 24th week of gestation was described, and the sensitivity and specificity of using FPG before the 24th gestational week to diagnose GDM among different pre-pregnancy BMI groups were reported. Differences in the means between groups were evaluated using independent sample t-test and analysis of variance. Pearson Chi-square test was used for categorical variables. RESULTS: The prevalence of GDM was 20.0% (6806/34,087) in the study population. FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week. FPG was higher in women with higher pre-pregnancy BMI. FPG before the 24th gestational week and pre-pregnancy BMI could be used to predict GDM. The incidence of GDM in women with FPG ≥5.10 mmol/L in the 19th to 24th gestational weeks and pre-pregnancy overweight or obesity was significantly higher than that in women with FPG ≥5.10 mmol/L and pre-pregnancy BMI <24.0 kg/m (78.5% [62/79] vs. 52.9% [64/121], χ = 13.425, P < 0.001). CONCLUSIONS FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week. Pre-pregnancy overweight or obesity was associated with an increased FPG value before the 24th gestational week. FPG ≥5.10 mmol/L between 19 and 24 gestational weeks should be treated as GDM in women with pre-pregnancy overweight and obesity.

Objective: To assess the feasibility of HEAD-US scale in the clinical application of hemophilic arthropathy (HA) and propose an optimized ultrasound scoring system. Methods: From July 2015 to August 2017, 1 035 joints ultrasonographic examinations were performed in 91 patients. Melchiorre, HEAD-US (Hemophilic Early Arthropathy Detection with UltraSound) and HEAD-US-C (HEAD-US in China) scale scores were used respectively to analyze the results. The correlations between three ultrasound scales and Hemophilia Joint Health Scores (HJHS) were evaluated. The sensitivity differences of the above Ultrasonic scoring systems in evaluation of HA were compared. Results: All the 91 patients were male, with median age of 16 (4-55) years old, including 86 cases of hemophilia A and 5 cases hemophilia B. The median (P₂₅, P₇₅) of Melchiorre, HEAD-US and HEAD-US-C scores of 1 035 joints were 2(0,6), 1(0,5) and 2(0,6), respectively, and the correlation coefficients compared with HJHS was 0.747, 0.762 and 0.765 respectively, with statistical significance (P<0.001). The positive rates of Melchiorre, HEAD-US-C and HEAD-US scale score were 63.0% (95%CI 59.7%-65.9%), 59.5% (95%CI 56.5%-62.4%) and 56.6% (95%CI 53.6%-59.6%) respectively, and the difference was statistically significant (P<0.001). Even for 336 cases of asymptomatic joints, the positive rates of Melchiorre, HEAD-US-C and HEAD-US scale score were 25.0% (95%CI 20.6%-29.6%), 17.0% (95%CI 12.6%-21.1%) and 11.9% (95%CI 8.4%-15.7%) respectively, and the difference was statistically significant (P<0.001). There were significant changes (P<0.05) in the ultrasonographic score of HA before and after onset of hemorrhage in 107 joints of 40 patients. The difference in variation amplitude of HEAD-US-C scores and HEAD-US scores before and after joint bleeding was statistically significant (P<0.001). Conclusion: Compared with Melchiorre, there were similar good correlations between HEAD-US, HEAD-US-C and HJHS. HEAD-US ultrasound scoring system is quick, convenient and simple to use. The optimized HEAD-US-C scale score is more sensitive than HEAD-US, especially for patients with HA who have subclinical state, which make up for insufficiency of sensitivity in HEAD-US scoring system.

Objective: To explore the evaluation of joint injury by HEAD-US-C (Hemophilic Early Arthropathy Detection with UltraSound in China, HEAD-US-C) in patients with moderate or severe hemophilia A treated with prophylaxis vs on-demand. Methods: The patients from June 2015 to July 2017 with moderate or severe hemophilia A were examined by ultrasound imaging of the elbows, knees and ankles; Meanwhile the HEAD-US-C ultrasound assessment scale and hemophilia joint health score scale 2.1 (HJHS2.1) were used to score the joint status. The correlation between the HEAD-US-C and HJHS score was performed in prophylaxis group and on-demand group patients, respectively. Results: A total of 925 cases of joint ultrasonography were conducted in 70 patients with moderate or severe hemophilia A. Among patients with moderate hemophilia, the median (IQR) of HEAD-US-C score and HJHS score in on-demand group were significantly higher than those in the prophylaxis group[1 (0, 6) vs 0.5 (0, 3) , z=0.177, P=0.046],[2 (0, 4) vs 2 (0, 3) z=0.375, P=0.007], even though there was no significant difference of the median (IQR) number of annualized target joints bleeding episodes between on-demand and prophylaxis groups[1 (0, 7) vs 1 (0, 5) , z=1.271, P=0.137]. Unlike in moderate cases, on-demand treatment group had more annualized target joints bleeding episodes than prophylaxis group among patients with severe hemophilia[3 (0, 8) vs 2 (0, 8) , z=0.780 P=0.037]. The prophylaxis group compared favorably with on-demand therapy group in terms of HEAD-US-C score[1 (0, 6) vs 4 (0, 7) , z=2.189, P=0.008], and HJHS score[2 (0, 5) , 4 (1, 6) , z=3646, P<0.001]for the severe hemophilia patients. The positive correlation between HEAD-US-C score and HJHS score was identified (P<0.05) , whether on-demand treatment or prophylaxis groups. The correlation coefficient between HEAD-US-C score and HJHS score in on-demand treatment and prophylaxis groups were 0.739 (95% CI 0.708-0.708) , 0.865 (95% CI 0.848-0.848) respectively, and 95% CI didn't overlap (P<0.05) , indicating that the correlation coefficient in prophylaxis group had stronger correlation than that in on-demand group. Conclusions: Clinical effects of prophylaxis were significantly better than those of on-demand treatment in patients with moderate or se-vere haemophilia A. HEAD-US-C scoring system could effectively evaluate joints damage in hemophilia A patients treated with on-demand or prophylaxis, companied by significantly positive correlation with HJHS clinical evaluation system, and provided objective index for clinical effect assessment.

OBJECTIVETo investigate the expression of N-cadherin in bone marrow leukemic cells derived from acute leukemia patients and its clinical significances.

METHODSA total of 113 patients with acute leukemia were enrolled in this study. Flow cytometry was employed to detect the expression of N-Cadherin in bone marrow leukemic cells from acute leukemia patients and the relationships between the N-cadherin expression and the clinical characteristics of patients with acute leukemia were analyzed.

RESULTSThe expression of N-Cadherin in bone marrow leukemic cells deriveted from patients with acute leukemia was variable with 0%-99.7%. For adult AML patients, the positive rate of CD34 in N-cadheringroup was significantly higher than that in N-cadheringroup(67.39% vs 33.33%)(P=0.013), while the differences of total CR rate and rate of CR after 1 cycle of induction treatment were not significant between these 2 groups(P>0.05). As to ALL patients, N-cadheringroup had significant lower WBC count (21.31±7.07 vs 51.10±23.69)(P=0.008) and lower percentage of peripheral blood blast (43.22±5.75% vs 66.45±5.65%)(P=0.015). The CR rate after 1 cycle of induction treatment and rate of overall CR were lower and the relapse rate was higher in N-cadherinALL group than those in N-cadherinALL group, but the differences were not significant (P>0.05). For childhood ALL, the positive rate of CD33 in N-cadheringroup was significantly higher than that in N-cadheringroup(47.62% vs 0%)(P=0.012). The relapse rate was higher in N-cadheringroup than that in N-cadheringroup (30.00% vs 0%)(P=0.115). The median survival time, 3-year overall OS rate and 3-year relapse-free survival rate in N-cadheringroups of adult AML, non-M3 AML, ALL and chidhood ALL paients were superior to N-cadheringroups, but the differences were not significant.

CONCLUSIONThe expression of N-cadherin in bone marrow leukemic cells relates to some clinical features of patients with acute leukemia and to some extent has inferior effect on survival of patients with acute leukemia.
