Objective:To explore the correlation among SMAD4 gene polymorphisms, early life traumatic experience and their interactions with clinical feature of obsessive-compulsive disorder (OCD). Methods:Totally 484 OCD patients who met the DSM-Ⅳ diagnostic criteria and 368 health controls who met the enrollment criteria were recruited from September 2013 to September 2018. The Yale-Brown obsessive-compulsive scale (Y-BOCS) was used to assess the severity of obsessive-compulsive symptoms, the Beck depression inventory Ⅱ (BDI-Ⅱ) was used to assess the severity of depressive symptoms, the Beck anxiety inventory (BAI) was used to assess the severity of anxiety symptoms, and early trauma inventory-short form (ETI-SF) was used to assess early traumatic experience. SMAD4: rs12452684, rs2276163, rs17663887 and rs3819122 were genotyped using the Taqman genotyping technique. Data were analyzed using SPSS 20.0 software, and comparisons among groups were performed using chi-square test, t-test, Mann-Whitney U non-parametric test and analysis of covariance. Correlation was analyzed using Spearman correlation analysis, and interactions were analyzed using general linear model. Results:All sites except rs17663887 met the Hardy-Weinberg equilibrium (rs12452684: χ2=0.29, P=0.59; rs2276163: χ2=2.58, P=0.11; rs3819122: χ2=0.22, P=0.64).Allele, genotype frequencies of SMAD4: rs12452684, rs2276163 and rs3819122 were not statistically significant between the OCD and the health control groups ( χ2=0.02, 1.20, 0.04, all P>0.05; χ2=1.85, 3.98, 1.45, all P>0.05). The results of covariance analysis (corrected for age and gender) showed that there were significantly differences in compulsion (CC: 12.47±4.23, CT: 12.53±4.15, TT: 13.97±3.11; AA: 12.63±4.08, AC: 12.49±4.19, CC: 13.87±2.93) and total Y-BOCS scores(CC: 25.31±6.42, CT: 25.68±5.90, TT: 27.75±6.01; AA: 25.54±6.52, AC: 25.56±5.98, CC: 27.63±5.75) among the three genotypes of the SMAD4: rs2276163 and rs3819122 between the two groups ( F=3.58, 3.87, 3.48, 3.73, all P<0.05). Emotional abuse in the ETI-SF was positively correlated with obsession and total Y-BOCS scores( r=0.14, 0.14, both P<0.05). The interactions of rs2276163, rs3819122 and emotional abuse were associated with obsession scores ( F=4.65, 3.63, 2.93, all P<0.01). Conclusions:The more emotional abuse experienced in early life, the more severe obsessive-compulsive symptoms, and the interaction between the SMAD4 gene and early traumatic experience is involved in the development of OCD.

Objective To investigate the status of self-advocacy and symptom burden in breast cancer patients undergoing chemotherapy and explore the correlations between them so as to provide a reference for relieving their symptom burden.Methods A total of 240 breast cancer patients undergoing chemotherapy who were treated in a general hospital in Hubei province from July 2021 to January 2022 were enrolled in the study by convenience sampling method.The general data questionnaire,female self-advocacy in cancer survivorship scale,and Chinese version of Anderson symptom assessment scale(MDASI)were applied in the investigation.Pearson correlation analysis was employed to explore the correlation between self-advocacy and symptom burden among breast cancer patients undergoing chemotherapy.Hierarchical regression was employed to analyze the effect of self-advocacy on symptom burden.Results A total of 240 patients completed the study.The total score of self-advocacy of the patients was(68.89±10.66),and the total score of symptom burden was(66.70±18.80).The two variables were significantly correlated in a negative way(r=-0.683,P<0.05).Hierarchical regression showed that self-advocacy ability independently explained 9.3%of the total variation in the symptom burden.Conclusions The incidences of various symptoms in breast cancer patients undergoing chemotherapy are high,and multiple symptoms coexist in the whole chemotherapy cycle.Symptom burden cannot be ignored,for it is negatively correlated with self-advocacy.Therefore,strengthening the concept and ability of self-advocacy can help reduce symptom burden of patients.

Objective:To investigate the effectiveness of suicide prevention cognitive behavioral therapy for depression patients with suicide attempt.Methods:Eligible participants were recruited from the inpatient department of Beijing Huilongguan Hospital from September 2021 to August 2022. A total of 112 patients were randomly allocated into the intervention group (56 cases) and the control group (56 cases) by a random number table. Patients in the intervention group received 12 sessions of cognitive behavioral therapy for suicide prevention over 8 weeks,while participants in the control group received supportive psychotherapy. Patient Health Questionnaire Depression Scale (PHQ-9) and the Beck Scale for Suicide Ideation-Chinese Version (BSI-CV) were used to assess changes in depressive symptoms,suicidal ideation,and suicidal tendencies in both groups at baseline,4-week of treatment,the end of treatment,and at follow-up (weekends 4,8,12). General data and scale scores between the two groups were analyzed by t test,Mann-Whitney rank sum test,and χ 2 test; repeated measure ANOVA were used to assess the baseline and intervention effects. Results:The change of PHQ-9 at each time point of the 2 groups showed a downward trend,and the group x time interaction was significant ( F=2.75, P=0.047). Since the 8th week,the PHQ score in the intervention group was significantly lower than that in the control group ( t=7.03, P<0.05). Time and group effect were significant in the four time points of the total score of suicidal ideation in the last week in BSI-CV ( F=96.78,6.35,both P<0.05),but the interaction between group and time was not significant. At weeks 8 and 12,the scores of the intervention group were lower than those of the control group ( Z=-3.11,-3.30;both P<0.01). In BSI-CV,time effects in the total score of suicidal intention was significant at four time points ( F=11.83, P<0.05),but the interaction between group and time was not significant ( F=2.56, P=0.059). There was no significant difference in suicide tendency between the two groups at each time point ( F=0.001, P=0.975). The total scores of suicidality in 2 groups at 4,8 and 12 weeks were all lower than baseline ( P<0.05). Conclusions:Compared with the control group,the cognitive behavioral therapy for suicide prevention showed superior effects on suicidal ideation and depression,but the intervention effect on suicidal tendency was not significant. Further studies are needed to investigate the long-term effects of cognitive behavioral therapy for suicide prevention in patients with depression who have attempted suicide.

Alfalfa (Medicago sativa) is an important food and feed crop which rich in mineral sources. The WUSCHEL-related homeobox (WOX) gene family plays important roles in plant development and identification of putative gene families, their structure, and potential functions is a primary step for not only understanding the genetic mechanisms behind various biological process but also for genetic improvement. A variety of computational tools, including MAFFT, HMMER, hidden Markov models, Pfam, SMART, MEGA, ProtTest, BLASTn, and BRAD, among others, were used. We identified 34 MsWOX genes based on a systematic analysis of the alfalfa plant genome spread in eight chromosomes. This is an expansion of the gene family which we attribute to observed chromosomal duplications. Sequence alignment analysis revealed 61 conserved proteins containing a homeodomain. Phylogenetic study sung reveal five evolutionary clades with 15 motif distributions. Gene structure analysis reveals various exon, intron, and untranslated structures which are consistent in genes from similar clades. Functional analysis prediction of promoter regions reveals various transcription binding sites containing key growth, development, and stress-responsive transcription factor families such as MYB, ERF, AP2, and NAC which are spread across the genes. Most of the genes are predicted to be in the nucleus. Also, there are duplication events in some genes which explain the expansion of the family. The present research provides a clue on the potential roles of MsWOX family genes that will be useful for further understanding their functional roles in alfalfa plants.

Long noncoding RNAs (lncRNAs) are expressed in different species and different tissues, and perform different functions, but little is known about their involvement in the synthesis or secretion of follicle-stimulating hormone (FSH). In general, we have revealed lncRNA‍‒‍microRNA (miRNA)‍‒‍‍messenger RNA (mRNA) interactions that may play important roles in rat primary pituitary cells. In this study, a new lncRNA was identified for the first time. First, we analyzed the gene expression of lncRNA-m18as1 in different tissues and different stages by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and observed the localization of lncRNA-m18as1 with fluorescence in situ hybridization, which indicated that this lncRNA was distributed mainly in the cytoplasm. Next, we used RT-qPCR and enzyme-linked immunosorbent assay (ELISA) to analyze the regulation of FSH synthesis and secretion after overexpression or knockdown of lncRNA-m18as1 and found that lncRNA-m18as1 was positively correlated with FSH synthesis and secretion. In addition, mothers against decapentaplegic homolog 2 (Smad2) was highly expressed in our sequencing results. We also screened miR-18a-5p from our sequencing results as a miRNA that may bind to lncRNA-m18as1 and Smad2. We used RNA immunoprecipitation-qPCR (RIP-qPCR) and/or dual luciferase assays to confirm that lncRNA-m18as1 interacted with miR-18a-5p and miR-18a-5p interacted with Smad2. Fluorescence in situ hybridization (FISH) showed that lncRNA-m18as1 and miR-18a-5p were localized mainly in the cytoplasm. Finally, we determined the relationship among lncRNA-m18as1, miR-18a-5p, and the Smad2/3 pathway. Overall, we found that lncRNA-m18as1 acts as a molecular sponge of miR-18a-5p to regulate the synthesis and secretion of FSH through the Smad2/3 pathway.

Objective: To investigate the clinical characteristics, treatments, and prognostic factors among patients with gestational trophoblastic neoplasia (GTN) exhibiting brain metastases who underwent craniotomy. Methods: Thirty-five patients with GTN who had brain metastases and subsequently underwent craniotomies between January 1990 and December 2018 at Peking Union Medical College Hospital were identified using the GTN database. Their clinical manifestations, treatments, outcomes, and prognostic factors were retrospectively analyzed. Results: All 35 patients underwent decompressive craniotomy, hematoma removal, and metastatic tumor resection combined with multiagent chemotherapy. Eighty percent (28/35) achieved complete remission, 11.4% (4/35) achieved partial remission, and 8.6% (3/35) had progressive disease. Not counting 2 patients who were lost to follow-up, 81.8% of the patients (27/33) were alive after a median follow-up of 72 months. The 5-year overall survival rate was 80.4%. Univariate analysis revealed that a history of chemotherapy failure (p=0.020) and a >1-week interval between craniotomy and chemotherapy commencement (p=0.027) were adverse risk factors for survival. Multivariate analysis showed that previous chemotherapy failure remained an independent risk factor for poor survival (odds ratio=11.50; 95% confidence interval=1.55–85.15; p=0.017). Conclusion Decompressive craniotomy is a life-saving option if metastatic hemorrhage and intracranial hypertension produce a risk of cerebral hernia in patients with GTN who have brain metastases. Higher survival rates and improved prognoses can be achieved through perioperative multidisciplinary cooperation and timely standard postoperative chemotherapy.

De novo variants (DNVs) are one of the most significant contributors to severe earlyonset genetic disorders such as autism spectrum disorder, intellectual disability, and other developmental and neuropsychiatric (DNP) disorders. Presently, a plethora of DNVs have been identified using next-generation sequencing, and many efforts have been made to understand their impact at the gene level. However, there has been little exploration of the effects at the isoform level. The brain contains a high level of alternative splicing and regulation, and exhibits a more divergent splicing program than other tissues. Therefore, it is crucial to explore variants at the transcriptional regulation level to better interpret the mechanisms underlying DNP disorders. To facilitate a better usage and improve the isoform-level interpretation of variants, we developed NeuroPsychiatric Mutation Knowledge Base (PsyMuKB). It contains a comprehensive, carefully curated list of DNVs with transcriptional and translational annotations to enable identification of isoformspecific mutations. PsyMuKB allows a flexible search of genes or variants and provides both table-based descriptions and associated visualizations, such as expression, transcript genomic structures, protein interactions, and the mutation sites mapped on the protein structures. It also provides an easy-to-use web interface, allowing users to rapidly visualize the locations and characteristics of mutations and the expression patterns of the impacted genes and isoforms. PsyMuKB thus constitutes a valuable resource for identifying tissue-specific DNVs for further functional studies of related disorders. PsyMuKB is freely accessible at http://psymukb.net.

Objective To explore the effect of information-motivation-behavioral (IMB) skills model on self-management behavior and self perceived burden of elderly patients with permanent bladder fistula. Methods A total of 92 elderly patients with permanent urinary bladder fistula were randomly divided into experiment group and control group in our hospital from November 2015 to November 2016, 46 cases in each group. In the control group, taking classes, face-to-face education were done for a total of 6 months once a month, 60 minutes each time. In the experiment group, the IMB model was used for the nursing intervention for a total of 6 months once a month, 60 minutes each time. The two groups of patients were assessed by self management behavior scale and self perceived burden scale. Results After the intervention, the score on self-management ability of the experiment group was (76.32 ± 4.73), higher than (67.22 ± 3.14) of the control group (P<0.05). The score on the self perceived burden of the experiment group was significantly lower than that of the control group (10.32 ± 4.48 vs. 19.98± 6.63, P<0.05). Conclusion The implementation of IMB model can improve the self-management behavior of elderly male patients with bladder fistula, and reduce the burden of self perception.
