Objective: To investigate the relationships among psychological resilience, parental control, and behavioral problems in middle school students, aiming to provide evidencebased recommendations for the prevention and intervention of behavioral issues in middle school students, as well as for the development of related policies. Methods: A stratified cluster sampling method was used to select 2 745 participants from three cities in Guizhou Province with different levels of economic development from August to December 2021. The Child Behavior Checklist (CBCL), Parental Control Questionnaire, and Psychological Resilience Questionnaire were administered to junior high school students and their parents. A network analysis method was employed to construct a network analysis model of factors influencing behavioral problems. Results: The detection rate of behavioral problems among junior high school students in Guizhou Province was 22.62%. The scores for psychological resilience (goal focus, emotional control, positive cognition, family support, and interpersonal assistance) and proactive inquiry in behavior control were higher in the group without behavioral problems than in the group with behavioral problems. Scores for psychological control (inducing guilt, with drawing affection, and asserting authority) were higher in the group with behavioral problems than in the group without behavioral problems, with statistically significant differences (t=9.80, 17.76, 6.21, 12.20, 13.18, 6.28, 11.58, 11.10, 10.74, P<0.05). The network model showed that among the same variable factors, the strongest connection weight was between inducing guilt and withdrawing affection, with a weight of 0.79. Between different variables, there were negative correlation between behavioral problems and psychological resilience (goal focus, emotional control, positive cognition, family support, interpersonal assistance) and behavior control (proactive inquiry, behavioral restraint) with correlation coefficients (r=-0.25, -0.42, -0.16, -0.31, -0.33, -0.17, -0.03, P<0.05), respectively. There were positive correlation between psychological control factors (inducing guilt, withdrawing affection, and asserting authority) and behavioral problems (r=0.29, 0.27, 0.27), and a negative correlation between these psychological control factors and psychological resilience factors (goal focus, emotional control, positive cognition, family support, interpersonal assistance)(r=-0.53--0.13)(P<0.05). The strongest connection weight was between withdrawing affection and family support, with a connection weight of -0.53. Family support was an important bridge symptom connecting the entire behavioral problem network model, with a high centrality. Conclusions The detection rate of behavioral problems among junior high school students in Guizhou Province is relatively high. Assisting adolescents in establishing a supportive family environment facilitates the cultivation of their psychological resilience, thereby mitigating the occurrence of behavioral problems.

  Objective  To evaluate the effect of intraoperative multimodal analgesia on the early postoperative quality of recovery in end-stage head and neck cancer patients undergoing open gastrostomy surgery.  Methods  This was a prospective, parallel, randomized controlled study. The research subjects were end-stage head and neck cancer patients who underwent elective open gastrostomy at Beijing Tongren Hospital affiliated to Capital Medical University from November 2022 to May 2023. The patients were randomly divided into local anesthesia group and multimodal analgesia group at a 1∶1 ratio. For local anesthesia group, 0.25% ropivacaine 20-30 mL was administered for local infiltration anesthesia. For multimodal analgesia group, the anesthesia method was nerve block + intravenous analgesia: ultrasound-guided left transverse abdominis plane block (0.25% ropivacaine 0.3 mL/kg)+bilateral rectus abdominis sheath block (0.25% ropivacaine 0.3 mL/kg per side)+intravenous injection of oxycodone 0.1 mg/kg, flurbiprofen 1 mg/kg, and dexamethasone 0.2 mg/kg. The primary outcome measure was the quality of requirements-15 (QoR-15) score at postoperative 24 h, while the secondary outcome measures were the QoR-15 score at postoperative 48 h, the numerical rating scale (NRS) and Bruggemann comfort scale (BCS) scores at different time points after the surgery, the first time of rescue analgesia, the first time of off-bed activity and intestinal exhaust, as well as the incidences of adverse reactions within postoperative 48 h.  Results  A total of 46 patients with end-stage head and neck cancer who underwent open gastrostomy and met the inclusion and exclusion criteria were ultimately enrolled, with 23 patients in multimodal analgesia group and 23 patients in local anesthesia group. There was no statistically significant difference in preoperative QoR-15 scores between the two groups (P > 0.05). Multimodal analgesia group had higher QoR-15 scores at 24 h postoperatively[(81.77±8.91) vs. (71.46±7.61), P < 0.05] and 48 h postoperatively[(86.26±7.92) vs. (80.13±6.98), P < 0.05], and the difference in QoR-15 scores at 24 h postoperatively was clinically significant. Compared with local anesthesia group, at 6 h and 24 h after surgery, the multimodal analgesia group showed a decrease in NRS scores at rest and during exercise, while the comfort BCS score increased (all P < 0.05). Multimodal analgesia group also had a delayed time for the first rescue analgesia, a reduced incidence of rescue analgesia within 48 h after surgery, an earlier time for first postoperative off-bed activity and intestinal exhaust (all P < 0.05). The incidence of adverse reactions in multimodal analgesia group and local anesthesia group was 8.70% and 13.04%, respectively, but the difference was not statistically significant (P > 0.05).  Conclusion  Intraoperative multimodal analgesia can effectively alleviate postoperative pain, increase the comfortable degree, shorten the first time of postoperative off-bed activity and intestinal exhaust, and accordingly improve the quality of early postoperative recovery in patients undergoing open gastrostomy.

Objective: To explore the current status related to behavioral problems among children and adolescents aged 12-16 years old in Guizhou Province, China, and to provide a reference for timely prevention and intervention measures. Methods: To capture different economic development levels, a multistage stratified cluster sampling method was used. A total of 3 217 children and adolescents aged 12-16 years old from six middle schools and six primary schools in Guiyang, Duyun, Kaili City from Guizhou Province participated in this study. The Achenbach Child Behavior Checklist (CBCL) and a self designed questionnaire were administered between August and December 2021. Results: The overall detection rate of behavioral problems among the students was 16.60% , and the rate was 14.41% and 18.62% among male and female students, respectively. The results of the Logistic regression analysis showed that good peer relationships ( OR=0.25, 0.16, P <0.05) were associated with a lower risk of behavioral problems in children and adolescents. However, the following factors were associated with an elevated risk of behavioral problems: nonparents as the main caregivers( OR = 1.44 ); children s daily screen time was 1-2 h ( OR =1.47) or more than 2 h( OR =2.75); children who had no sports hobbies( OR = 1.36); father parenting for doting or neglect( OR =1.85, 2.01); maternal parenting for doting( OR = 2.12 ); father had bad life habits( OR =1.69); father and mother were occasionally sick( OR =1.30, 1.38)( P <0.05). Conclusion Behavioral problems among children and adolescents in Guizhou Province is related to children s unhealthy living habits and various factors in the family environment. It is suggested that families, schools and relevant functional departments give full play to their own advantages and take comprehensive measures to prevent the occurrence of behavioral problems among children and adolescents.

Objective:To investigate the association of metabolic syndrome(MS) with cardiovascular disease(CVD) mortality and all-cause mortality in peritoneal dialysis patients.Methods:A retrospective analysis was performed on patients who underwent peritoneal dialysis from January 1, 2013 to July 31, 2021 in the Shaoxing People′s Hospital. Patients were divided into MS group and non-MS group. The differences in baseline biochemical variables, comorbidities, and clinical outcomes between the two groups were compared. Kaplan-Meier method was used to obtain survival curves, the Cox regression model was used to evaluate the influence of MS for survival rates, and the inverse probability of treatment weighting(IPTW) was used to eliminate influence of the confounders in the groups.Results:A total of 494 peritoneal dialysis patients were enrolled in this study, which were divided into MS group( n=266) and non-MS group( n=228). The total median follow-up time was(31±22) months. At baseline, the standard mean difference( SMD) in smoking history, drinking history, CVD history, prevalence of chronic glomerulonephritis, left ventricular ejection fraction, B-type natriuretic peptides, hemoglobin, blood calcium, hypersensitive C-reactive-protein, intact parathyroid hormone, ultrafiltration and 4 h dialysate/plasma creatinine in the two groups were greater than 0.1. Their SMD decreased to under 0.1 after IPTW, showing a good balance between the two groups. The analysis of the survival curve of Kaplan Meier showed that the cumulative survival rate and cumulative CVD survival rate in MS group were significantly lower than those in non-MS group before and after IPTW( P<0.05). After IPTW was used to eliminate the effect of confounders, multivariate Cox regression analysis still displayed that MS was an independent risk factor for all-cause mortality( HR=1.824, 95% CI 1.121-2.968, P=0.015) and CVD mortality( HR=2.470, 95% CI 1.324-4.609, P=0.004)in peritoneal dialysis patients. Conclusion:The prevalence of metabolic syndrome is high in peritoneal dialysis patients. MS is an independent risk factor for all-cause mortality and CVD mortality in peritoneal dialysis patients.

The incidence and mortality of lung cancer rank first among all malignant tumors in China. With the popularization of high resolution computed tomography (CT) in clinic, chest CT has become an important means of clinical screening for early lung cancer and reducing the mortality of lung cancer. Imaging findings of early lung adenocarcinoma often show partial solid nodules with ground glass components. With the development of imaging, the relationship between the imaging features of some solid nodules and their prognosis has attracted more and more attention. At the same time, with the development of 3D-reconstruction technology, clinicians can improve the accuracy of diagnosis and treatment of such nodules.This article focuses on the traditional imaging analysis of partial solid nodules and the imaging analysis based on 3D reconstruction, and systematically expounds the advantages and disadvantages of both.

BACKGROUND: At present, the research progress of targeted therapy for epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) gene mutations in lung adenocarcinoma is very rapid, which brings new hope for the treatment of advanced lung adenocarcinoma patients. However, the specific imaging and pathological features of EGFR and ALK gene mutations in adenocarcinoma are still controversial. This study will further explore the correlation between EGFR, ALK gene mutations and imaging and pathological features in invasive lung adenocarcinoma. METHODS: A total of 525 patients with lung adenocarcinoma who underwent surgery in our center from January 2018 to December 2019 were included. According to the results of postoperative gene detection, the patients were divided into EGFR gene mutation group, ALK gene mutation group and wild group, and the EGFR gene mutation group was divided into exon 19 and exon 21 subtypes. The pathological features of the mutation group and wild group, such as histological subtype, lymph node metastasis, visceral pleural invasion (VPI) and imaging features such as tumor diameter, consolidation tumor ratio (CTR), lobulation sign, spiculation sign, pleural retraction sign, air bronchus sign and vacuole sign were analyzed by univariate analysis and multivariate Logistic regression analysis to explore whether the gene mutation group had specific manifestations. RESULTS: EGFR gene mutation group was common in women (OR=2.041, P=0.001), with more pleural traction sign (OR=1.506, P=0.042), and had little correlation with lymph node metastasis and VPI (P>0.05). Among them, exon 21 subtype was more common in older (OR=1.022, P=0.036), women (OR=2.010, P=0.007), and was associated with larger tumor diameter (OR=1.360, P=0.039) and pleural traction sign (OR=1.754, P=0.029). Exon 19 subtype was common in women (OR=2.230, P=0.009), with a high proportion of solid components (OR=1.589, P=0.047) and more lobulation sign (OR=2.762, P=0.026). ALK gene mutations were likely to occur in younger patients (OR=2.950, P=0.045), with somking history (OR=1.070, P=0.002), and there were more micropapillary components (OR=4.184, P=0.019) and VPI (OR=2.986, P=0.034) in pathology. CONCLUSIONS The EGFR and ALK genes mutated adenocarcinomas have specific imaging and clinicopathological features, and the mutations in exon 19 or exon 21 subtype have different imaging features, which is of great significance in guiding the clinical diagnosis and treatment of pulmonary nodules.

Objective:To investigate the effects of chronic stress during pregnancy on depressive behavior and DNA methylation of insulin-like growth factor-2 ( IGF-2 )/long non-coding RNA ( lncRNA ) H19 in hippocampus of female offspring rats.Methods:A total of 32 SPF female SD rats were divided into model group and control group according to the random number table. The rats in the model group were treated with chronic unpredictable mild stress (CUMS) to establish the depression model, and the rats in the control group were fed normally.On the 7th day of stress stimulation, all female rats mated with male rats. One day before stress stimulation and 1, 7, 14, 21, 28 days after stress stimulation, blood samples were collected from the inner canthus vein of the rats to determine the plasma corticosterone concentration. Eight female pups were randomly selected from each group on postnatal day 28(PND28) and postnatal day 42 (PND42). Plasma corticosterone concentration was measured after angular vein blood collection. At PND42, the depression-like behavior of female pups in the two groups was measured by sucrose preference test, tail suspension test and forced swimming test. The expression of IGF-2/H19 and related transferases in hippocampus of offspring rats was detected by RT-PCR and Western blot. Methyl target technology was used to capture and sequence 19 CpG sites of IGF-2 differentially methylated region(DMR) fragment 2, 8 CpG sites in H19 imprinting control region (ICR) fragment 1 and 15 CpG sites in H19-ICR fragment 2, and calculate the methylation level of each CpG site. SPSS 26.0 was used for statistical analysis of relevant data by repeated measurement ANOVA, t test and non-parametric test. Results:(1) The data of plasma corticosterone content of the two groups of female rats at different times were analyzed by repeated measurement variance.The results showed that the the interaction effect between time and group was not significant ( F=2.997, P=0.066), and the main effect of time was significant ( F=4.44, P=0.010). The main effect of group was significant ( F=41.40, P=0.001). According to the independent effect analysis of factors between groups, on the 14th, 21st, and 28th days of stress, the plasma corticosterone concentration of the model group was higher than that of the control group (all P<0.001). (2) In the sucrose preference test, the total liquid consumption (11.10(10.38, 11.58) mL, 13.55(12.00, 15.77) mL, Z=-3.055, P=0.002), 1% sucrose water consumption ((5.50±1.30) mL, (8.56±2.04) mL, t=-3.582, P=0.003) and 1% sucrose preference percentage ( (51.35±8.69) %, (62.11±8.05) %, t=-2.576, P=0.022) of female pups in the model group were significantly lower than those in the control group. (3) The duration of immobility in tail suspension test ((126.95±39.89) s, (54.30±25.00) s, t=4.375, P=0.001) and forced swimming test ((7.97±6.66) s, (1.85±2.12) s, t=2.478, P=0.037) of female offspring in the model group were longer than those in the control group. (4) The expression of IGF-2 mRNA ((0.46±0.24), (1.00±0.00), t=3.821, P=0.019) and H19 mRNA ((0.60±0.25), (1.00±0.00), t=3.574, P=0.007) in hippocampus of female pups in the model group were lower than those of control group. The relative expression of IGF-2 protein in female offspring of model group was lower than that in control group ((0.77±0.04), (1.00±0.00), t=9.876, P=0.01). The relative expression of CCTC-binding factor (CTCF) mRNA ((1.29±0.12), (1.00±0.00), t=-4.850, P=0.003) and protein ((1.90±0.28), (1.00±0.00), t=-5.513, P=0.005) were higher than those in the control group. (5) The methylation levels of three CpG sites in the IGF-2 DMR region of female offspring in the model group were lower than those in the control group ( t=-3.21, -3.00, -3.34, all P<0.05), located at chr1215831028, chr1215831055 and chr1215831205, respectively. The methylation level of IGF-2 DMR fragment was lower than that of the control group ( t=-3.453, P=0.048). The relative expression levels of DNMT3A mRNA ( t=5.102, P=0.002), DNMT3A ( t=10.213, P<0.001) and DNMT3B ( t=4.169, P=0.014) in female offspring of the model group were lower than those in the control group. Conclusion:Chronic stress during pregnancy causes depression and despair in female offspring mice, and the mechanism may be related to the decrease of methylation level of imprinted gene IGF-2 DMR caused by the decrease of methyltransferase expression.
