Objective: To explore the relationship between parenting styles and depressive symptoms in adolescents with nightmare disorder, so as to provide a scientific basis for formulating effective family intervention measures and psychological counseling. Methods: From January 2023 to August 2024, 90 adolescents diagnosed with nightmare disorder and admitted to Hangzhou Seventh Peoples Hospital, along with 176 healthy controls from the urban areas of Hangzhou, were recruited as participants in the study. All participants were assessed using the Nightmare Experience Questionnaire (NEQ), Family Relationship Questionnaire (FRQ), and Plutchik-van Praag Selfreport Depression Scale (PVP). The ttest and Chisquare test were conducted to compare two groups. Pearson correlation and stepwise multiple linear regression were employed to explore the correlations between PVP and NEQ or FRQ. The Process model was used to testing the mediating effects among NEQ/FRQ/PVP. Results: The nightmare disorder group had higher scores in nightmare frequency, the four factors of NEQ (physical effect, negative emotion, meaning interpretation, horrible stimulation), and PVP than the healthy control group (24.86±18.89, 10.12±3.67, 19.01±3.51, 17.02±3.31, 15.14±3.26, 14.02±4.38; 2.34±1.04, 6.49±2.18, 17.63±4.76, 13.91±4.24, 12.40±4.49, 9.39±3.28)(t=15.79, 10.11, 2.43, 6.09, 5.14, 27.46, P<0.05). The nightmare disorder group reported significantly lower scores in FRQ general attachment and maternal encouragement than the healthy control group (7.22±2.81, 16.39±3.28) (t=-5.53, -4.95). In contrast, they exhibited significantly higher scores in maternal abuse, maternal dominance, paternal freedom release, and paternal dominance than the healthy control group (8.23±1.80, 13.11±3.73, 18.36±3.37, 12.04±3.29; 6.07±1.85, 8.48±3.80, 15.15±2.51, 9.47±3.03) (t=6.70, 8.96, 5.90, 7.04, P<0.01). The results of Pearson correlation analysis showed that, in the nightmare disorder group, the PVP score was positively correlated with negative emotion, nightmare frequency, maternal abuse, and maternal dominance score (r=0.14, 0.63, 0.26, 0.51, P<0.05). The results of multiple linear regression analysis showed that when using FRQ score to predict NEQ score, the adjusted R2 in the nightmare disorder group was 0.01-0.59. Mother abuse could prediced physical effect (β=0.33); maternal dominance significantly predicted negative emotion, horrible stimulation, and nightmare frequency (β=0.29, 0.30, 0.79); paternal freedom release could predict negative emotion (β=0.26), paternal dominance predicted both negative emotion and nightmare frequency (β=0.22, 0.45) (P<0.05). Mediation analysis further revealed that, in the nightmare disorder group, PVP scores served as a mediating variable between FRQ and NEQ. Conclusion Abusive, controlling, and neglectful family upbringing styles as well as depression maybe are key factors that may contribute to the development of nightmare disorder among adolescents.

Objective To investigate the role of RNA-binding motif protein X-linked(RBMX)in regulating the proliferation,migration,invasion and glycolysis in human bladder cancer cells.Methods A lentivirus vectors system and RNA interference technique were used to construct bladder cancer 1376 and UC-3 cell models with RBMX overexpression and knockdown,respectively,and successful cell modeling was verified using RT-qPCR and Western blotting.Proliferation and colony forming ability of the cells were evaluated using EdU assay and colony-forming assay,and cell migration and invasion abilities were determined using Transwell experiment.The expressions of glycolysis-related proteins M1 pyruvate kinase(PKM1)and M2 pyruvate kinase(PKM2)were detected using Western blotting.The effects of RBMX overexpression and knockdown on glycolysis in the bladder cancer cells were assessed using glucose and lactic acid detection kits.Results RT-qPCR and Western blotting confirmed successful construction of 1376 and UC-3 cell models with RBMX overexpression and knockdown.RBMX overexpression significantly inhibited the proliferation,clone formation,migration and invasion of bladder cancer cells,while RBMX knockdown produced the opposite effects.Western blotting results showed that RBMX overexpression increased the expression of PKM1 and decreased the expression of PKM2,while RBMX knockdown produced the opposite effects.Glucose consumption and lactate production levels were significantly lowered in the cells with RBMX overexpression(P<0.05)but increased significantly following RBMX knockdown(P<0.05).Conclusion RBMX overexpression inhibits bladder cancer progression and lowers glycolysis level in bladder cancer cells by downregulating PKM2 expression,suggesting the potential of RBMX as a molecular target for diagnosis and treatment of bladder cancer.

Objective·To investigate the expression of miR-146a in peripheral blood CD4+T lymphocytes of patients with rheumatoid arthritis(RA)and its correlation with inflammatory cytokines such as tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6).Methods·A total of 30 active RA patients who received medical treatment and 30 healthy controls who underwent physical examinations at the People's Hospital of Longhua,Shenzhen from August 2019 to July 2021 were selected.Peripheral blood mononuclear cells(PBMCs)and CD4+T lymphocytes were isolated from venous blood extracted from RA patients and healthy controls,respectively.Quantitative real-time PCR(qPCR)was used to detect the expression of miR-146a in peripheral blood CD4+T lymphocytes,and enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of TNF-α and IL-6.After transfection of the peripheral blood CD4+T lymphocytes of RA patients with miR-146a mimic,the expression of miR-146a,TNF-α and IL-6 was detected again.The correlations between miR-146a expression and TNF-α and IL-6 expression in RA patients,both before and after transfection,were analyzed by using Pearson correlation coefficient.Results·Before transfection with miR-146a mimic,the expression levels of miR-146a,TNF-α and IL-6 in peripheral blood CD4+T lymphocytes of RA patients were significantly higher than those of healthy controls(all P＜0.001).After transfection,the expression of miR-146a in peripheral blood CD4+T lymphocytes of RA patients was significantly higher,and the expression of TNF-α and IL-6 was significantly lower(all P＜0.001).The results of Pearson correlation analysis showed that the expression of miR-146a in peripheral blood CD4+T lymphocytes of RA patients,both before and after transfection,was positively correlated with the expression of TNF-α and IL-6,respectively(r=0.959,P＜0.001;r=0.916,P＜0.001;r=0.971,P＜0.001;r=0.861,P＜0.001).Conclusion·miR-146a can regulate the levels of TNF-α and IL-6 in peripheral blood CD4+T lymphocytes of RA patients,indicating that miR-146a may play a role in the pathogenesis of RA.

Objective To explore the CT imaging features and independent risk factors for cystic pulmonary nodules and establish a malignant probability prediction model. Methods The patients with cystic pulmonary nodules admitted to the Department of Thoracic Surgery of the First People's Hospital of Neijiang from January 2017 to February 2022 were retrospectively enrolled. They were divided into a malignant group and a benign group according to the pathological results. The clinical data and preoperative chest CT imaging features of the two groups were collected, and the independent risk factors for malignant cystic pulmonary nodules were screened out by logistic regression analysis, so as to establish a prediction model for benign and malignant cystic pulmonary nodules. Results A total of 107 patients were enrolled. There were 76 patients in the malignant group, including 36 males and 40 females, with an average age of 59.65±11.74 years. There were 31 patients in the benign group, including 16 males and 15 females, with an average age of 58.96±13.91 years. Multivariate logistic analysis showed that the special CT imaging features such as cystic wall nodules [OR=3.538, 95%CI (1.231, 10.164), P=0.019], short burrs [OR=4.106, 95%CI (1.454, 11.598), P=0.008], cystic wall morphology [OR=6.978, 95%CI (2.374, 20.505), P<0.001], and the number of cysts [OR=4.179, 95%CI (1.438, 12.146), P=0.009] were independent risk factors for cystic lung cancer. A prediction model was established: P=ex/(1+ex), X=–2.453+1.264×cystic wall nodules+1.412×short burrs+1.943×cystic wall morphology+1.430×the number of cysts. The area under the receiver operating charateristic curve was 0.830, the sensitivity was 82.9%, and the specificity was 74.2%. Conclusion Cystic wall nodules, short burrs, cystic wall morphology, and the number of cysts are the independent risk factors for cystic lung cancer, and the established prediction model can be used as a screening method for cystic pulmonary nodules.

Objective:To review the application of pediatric magnetic resonance enterography (MRE) at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from 2012 to 2023, and to provide referenceable data for MRE use in complex pediatric clinical scenarios.Methods:This study was a cross-sectional study. The clinical and imaging data from children aged≤18 years who underwent MRE at Tongji Hospital between December 2012 and December 2023 were retrospectively analyzed. Out of 186 children who intended to receive the MRE examination, 12 failed, remainder 174 participants (mean age 14±4 years, range 1 month to 18 years) were included. Participants were categorized into an inflammatory bowel disease (IBD) group (118 cases) and a non-IBD group (56 cases), and further divided by age into infants (0-6 years, 8 cases), children (7-12 years, 37 cases), and adolescents (13-18 years, 129 cases). The overall image quality and the intestinal filling quality were scored using a 5-point scale. Statistical analyses included χ2 tests for age distribution, history of intestinal reconstruction surgery, and MRE success rates between IBD and non-IBD groups. Mann-Whitney U test was employed to compare subjective image quality scores between the abovementioned two groups. The Kruskal-Wallis test was used to detect the differences among the three age groups. Results:The success rate of MRE significantly increased with age: 66.7% (8/12) in infants, 88.1% (37/42) in children, and 97.7% (129/132) in adolescents ( χ2=15.39, P<0.001). A statistically significant difference in age distribution was observed between the IBD and non-IBD groups ( χ2=17.94, P<0.001). The proportion of infants in the non-IBD group was 14.3% (8/56), which was higher than that of the IBD group. The majority of the IBD group were adolescents, accounting for 78.8% (93/118). There was a statistically significant difference in the intestinal reconstruction surgery history ( χ2=2.83, P=0.005). The non-IBD group had a higher incidence of intestinal reconstructive surgery (21.4%, 12/56), compared to the IBD group (6.8%, 8/118). MRE intestinal filling quality or overall image quality scores between the IBD and non-IBD groups or among different age sub-groups were not statistically significant ( P>0.05). Conclusion:Juvenilization of non-IBD children and intestinal reconstructive surgery history could make the inspection more complex. High-quality imaging can still be achieved by adhering to technical specifications.

Objective:To explore the effect of the developmental stages and quality on pregnancy outcome and birth outcome, and provide evidence for single blastocyst selection in frozen-thawed cycles.Methods:A retrospective cohort study analysis was performed on the data of patients with a total of 893 cycles who underwent single blastocyst transfer in frozen-thawed cycles in the Center for Reproductive Medicine, Qingyuan People's Hospital from January 2013 to June 2021. The cycles were divided into day 5 (D5) and day 6 (D6) groups according to the time of blastocyst formation. Then the two groups were divided into four subgroups according to the quality of blastocyst, namely, D5 good-quality embryo subgroup, D5 non-good-quality embryo subgroup, D6 good-quality embryo subgroup and D6 non-good-quality embryo subgroup. The general data, clinical outcomes and neonatal outcomes of each group were compared.Results:1) The clinical pregnancy rate [60.14% (332/552)], the implantation rate [60.14% (332/552)] and the live birth rate [47.64% (263/552)] in D5 group were significantly higher than those in D6 group [45.75% (156/341), 45.75% (156/341), 36.36% (124/341), all P<0.001], but there were no significant differences in body mass index, duration of infertility, intimal thickness of transplantation day and miscarriage rate between the two groups (all P>0.05). In addition, there were also no significant differences in birth weight, low birth weight rate, fetal macrosomia rate and male/female ratio (all P>0.05). 2) There were significant differences in clinical pregnancy rate [61.00% (294/482), 54.29% (38/70), 51.00% (127/249), 31.52% (29/92)] and live birth rate [48.96% (236/482), 38.57% (27/70), 41.37% (103/249), 22.83% (21/92)] among D5 good-quality embryo subgroup, D5 non-good-quality embryo subgroup, D6 good-quality embryo subgroup and D6 non-good-quality embryo subgroup (all P<0.001). D5 good-quality embryo subgroup had the highest clinical pregnancy rate and live birth rate, while D6 non-good-quality embryo subgroup had the lowest clinical pregnancy rate and live birth rate. There were also no significant differences in birth weight, fetal macrosomia rate and male/female ratio among the four subgroups (all P>0.05), while there was a significant difference in low birth weight rate [5.08% (12/236), 0 (0/27), 4.85% (5/103), 23.81% (5/21)] among the four subgroups ( P=0.014). 3) There were no significant differences in clinical pregnancy rate and live birth rate between D5 non-good-quality embryo subgroup and D6 good-quality embryo subgroup (all P>0.05). The clinical pregnancy rate and the live birth rate of 4BC in D5 were lower than those of 4AA, 4AB and 4BA in D6, while the miscarriage rate of 4BC in D5 was higher than that of 4AA, 4AB and 4BA in D6, but there were no significant differences (all P>0.05).The clinical pregnancy rate and the live birth rate of 4BC in D5 were higher than those of 4BB in D6, but there were no significant differences (all P>0.05). Conclusion:In the frozen-thawed cycle of single blastocyst transplantation, D5 good-quality blastocysts are preferred. When faced with D5 non-good-quality embryos and D6 good-quality embryos, the optimal choice was D6 4AA>D6 4BA>D6 4AB>D5 4BC>D6 4BB.

Objective:To investigate the effect of conventional treatment plus long-term transcranial direct current stimulation (tDCS) on consciousness recovery in patients with minimally conscious state (MCS) after traumatic brain injury (TBI).Methods:A retrospective cohort study was conducted to analyze the clinical data of 60 patients with MCS after TBI admitted to Zhejiang Armed Police Corps Hospital from January 2019 to December 2020, including 38 males and 22 females, aged 19-60 years [(45.7±11.4)years]. Course of disease was 3-6 months [(4.6±0.9)months]. Of all, 30 patients received internal medicine, hyperbaric oxygen, rehabilitation and other conventional treatment (conventional treatment group), and 30 patients received tDCS stimulation on the basis of conventional treatment (tDCS treatment group). The tDCS stimulation contained 4 cycles for 28 days with each cycle lasting for 7 days (stimulation for 5 days, rest for 2 days). Coma recovery scale-revised (CRS-R) total score, brainstem auditory evoked potential (BAEP) score and clinical effictive rate (significantly effective+effective) were compared between the two groups before treatment, during 4 cycles of treatment and at 6 months and 12 months after treatment. Complications induced by tDCS were also evaluated.Results:There was no significant difference in CRS-R total score and BAEP score between the two groups before treatment (all P>0.05). CRS-R total score and BAEP score in tDCS treatment group were significantly higher than those in conventional treatment group during 4 cycles of treatment and at 6 months and 12 months after treatment (all P<0.05). CRS-R total score and BAEP score in both groups gradually increased during 4 cycles of treatment and at 6 months and 12 months after treatment (all P<0.05). The clinical effective rate in tDCS treatment group was 73% (22/30) when compared to 57% (17/30) in conventional treatment group ( P<0.05). In tDCS treatment group, 10 patients had local reversible slight redness at the cathodal position, while no other serious adverse effects, such as local burns, ulceration, exudation or epilepsy. Conclusion:Compared with conventional treatment, conventional treatment plus long-term tDCS can be more effective in improving the state of consciousness without serious adverse effects for MCS patients after TBI.

Objective:To design an oral methotrexate auxiliary device and explore the effect of methotrexate in patients with rheumatoid arthritis.Methods:Totally 30 patients with rheumatoid arthritis were selected and observed continuously for 12 months, from January to June in 2021, in the Affiliated Changzhou No. 2 People ′s Hospital of Naijing Medical University. The subjects took the medicine routinely in the first 6 months after entering the group, and the methotrexate oral drug assistant device was given in the latter 6 months to remind them to take the medicine correctly. Medication administration of patients before and after using the auxiliary device was compared, and the evaluation indexes such as disease activity, medication compliance and anxiety were observed. Results:Without the auxiliary device, there were 14 cases (46.67%) of medication error, 13 cases (43.33%) of medication time error, 9 cases (30.00%) of missed administration, while after the use of the auxiliary device, there were 4 cases (13.33%) of medication error, 2 cases (6.67%) of medication time error and 2 cases (6.67%) of missed administration, and the differences were statistically significant ( χ2=8.10, 9.09, 5.14, all P<0.05). Moreover, before using the auxiliary device, the scores of disease activity and medication compliance were 3.92 ± 0.95, 84.97 ± 6.49, respectively, while with the help of the auxiliary device, those scores changed to 3.29 ± 0.83, 92.40 ± 4.17 respectively. All the differences were statistically significant ( t=10.06, -10.37, both P<0.01). 16 cases (53.33%) were anxious after using the assistive device, which was also better than 26 cases (86.67%) before using the device. The difference was statistically significant ( χ2=8.10, P<0.01) . Conclusions:Oral administration aid for methotrexate can help rheumatoid arthritis patients to take methotrexate correctly and safely, reducing disease activity and anxiety, improving drug compliance. It is worthy to clinical promotion.
