Objective:To explore the effect of narrative nursing on the psychological resilience, self-esteem, and medication compliance of adolescent depression patients.Methods:This study is a quasi-experimental study. From August 2021 to January 2022, 86 adolescent depression patients admitted to the Department of Mental Health at the First Hospital of Shanxi Medical University were selected as the subject by convenience sampling. According to the order of admission time, the patients were divided into a control group and an intervention group, with 43 patients in each group. The control group received routine nursing, while the intervention group received narrative nursing on the basis of routine nursing. We compared the scores of the Self-Rating Depression Scale (SDS), Hamilton Depression Scale (HAMD), Self-Esteem Scale (SES), Connor-Davidson Resilience Scale (CD-RISC), and Morisky Medication Adherence Scale (MMAS-8) before and after intervention between two groups of patients.Results:Before intervention, there was no statistically significant difference in SDS, HAMD, SES, CD-RISC, and MMAS-8 scores between the two groups ( P>0.05). After intervention, the total scores of SDS and HAMD in the intervention group were lower than those before intervention and in the control group, and the toughness, optimism, self-improvement scores and the CD-RISC total score, SES scores and MMAS-8 scores were higher than those before intervention and in the control group, with statistically significant differences ( P<0.05) . Conclusions:Narrative nursing can improve the depressive mood of adolescent depression patients, enhance their psychological resilience, self-esteem, and medication compliance, and can be promoted and applied in clinical practice.

Objective:To investigate the predictive value of diffusion tensor imaging (DTI) parameters in upper extremity motor function recovery after surgery in patients with acute cervical spinal cord injury (CSCI).Methods:Twenty-three patients with acute CSCI who received postoperative systemic rehabilitation therapy in Department of Neurosurgery, 900 th Hospital of Joint Logistics Team of People's Liberation Army from May 2019 to July 2021 were selected as an experimental group, and 22 healthy subjects (healthy control group) matched with age and gender were selected from Physical Examination Center of the same hospital at the same period. Routine MRI sequence and DTI scan of the cervical spinal cord, scale of American Association for Spinal Cord Injury (ASIA) and modified Barthe index (mBI) were performed in patients of the experimental group 1 d and 3 months after surgery. Routine MRI sequence and DTI scan of the cervical spinal cord were performed in healthy subjects after enrollment. The DTI parameters in different regions between the two groups were compared, and the differences in DTI parameters, ASIA scores and mBI in patients of the experimental group before and after surgery were compared. Correlations of preoperative DTI parameters with preoperative upper extremity motor ASIA scores and upper extremity motor recovery rate 3 months after surgery were analyzed by Pearson correlation analysis. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of preoperative fractional anisotropy (FA) in upper extremity motor function recovery in CSCI patients 3 months after surgery. Results:As compared with the healthy control group, the experimental group had significantly lower preoperative FA in the injury area and distal injury area, and statistically higher preoperative apparent diffusion coefficient (ADC, P<0.05). In patients of the experimental group, preoperative FA in the injury area was significantly lower and ADC in the injury area was significantly higher as compared with those in the distal injury area ( P<0.05); patients of the experimental group had significantly higher FA in these two regions, upper extremity motor ASIA scores and mBI, and significantly lower ADC 3 months after surgery as compared with those 1 d before surgery ( P<0.05). The preoperative FA in the injury area and distal injury area in CSCI patients were positively correlated with preoperative upper extremity motor ASIA scores and upper extremity motor recovery rate 3 months after surgery ( P<0.05). ROC curve results showed that the area under the curve (AUC) of preoperative FA in injury area in predicting upper extremity motor function recovery 3 months after surgery was 0.912 ( 95%CI: 0.783-1.000, P<0.001); that of preoperative FA in the distal injury area was 0.842 ( 95%CI: 0.682-1.000, P<0.001). Conclusion:DTI parameters FA and ADC are sensitive indicators for detecting CSCI; preoperative FA in the injury area and distal injury area can be used to predict the upper extremity motor function recovery, but the efficacy of the former is superior to that of the later.

Objective:To analyze the expression of FAT1 gene in pancreatic adenocarcinoma and its relationship with clinicopathological features, prognosis, and immunotherapy for pancreatic adenocarcinoma.Methods:(1) Bioinformatics analysis: based on FAT1 mRNA expression and clinical data of 179 cases of pancreatic adenocarcinoma in the TCGA database, and FAT1 mRNA expression data of 328 cases of normal pancreatic tissues in the GTEx database. We analyzed the differences in FAT1 mRNA expression in pancreatic adenocarcinoma and normal pancreatic tissues and the relationship between FAT1 mRNA expression and the degree of differentiation, clinical stage, prognosis, immune cell infiltration, and immune checkpoint-associated genes in pancreatic adenocarcinoma. FAT1-related differentially expressed genes were analyzed by applying Limma 3.40.2 software package, and GO and KEGG enrichment analysis was performed on the differentially expressed genes. Immunohistochemical (IHC) of FAT1 in pancreatic adenocarcinoma and normal pancreatic tissues was analyzed by HPA database. (2) Validation of own tissue samples: tissue samples and clinical and prognostic data of 192 patients with pancreatic ductal adenocarcinoma admitted to Zhejiang Cancer Hospital from March 8, 2010 to September 30, 2020 were collected. IHC was performed on the tissue samples to verify the protein expression of FAT1 in pancreatic adenocarcinoma and its relationship with immune-related proteins, the degree of differentiation of pancreatic adenocarcinoma, clinical staging, and prognosis.Results:(1) Bioinformatics analysis: the FAT1 mRNA expression of 179 pancreatic adenocarcinoma tissues from the TCGA database was 5.55±1.04, which was higher than that of 328 normal pancreatic tissues with FAT1 mRNA from the GTEx database (2.95±0.53, P＜0.001). FAT1-specific IHC images showed that FAT1 expression was generally high in pancreatic adenocarcinoma tissues, and FAT1 expression shifted from the cell membrane to the cytoplasm. The FAT1 mRNA expression in the highly differentiated group (31 cases), the moderately differentiated group (96 cases), and the lowly differentiated group (52 cases) were 4.99±1.46, 5.51±0.80, and 5.68±1.08, the expression of pancreatic adenocarcinoma tissues were all higher than that of normal pancreatic tissues (all P＜0.001), and the FAT1 mRNA expression of the moderately differentiated group and the poorly differentiated group were all higher than that of the highly differentiated group (all P＜0.001). The median progression-free survival time (PFS) and median overall survival time (OS) of the 90 patients in the FAT1 mRNA low-expression group were 16.5 and 24 months, respectively, which were longer than those of the 89 patients in the FAT1 mRNA high-expression group (median PFS and OS were 13 and 18 months, respectively; P-values were 0.011 and 0.005, respectively). Multifactorial Cox regression analysis showed that FAT1 mRNA expression level was an independent influencing factor for OS in pancreatic adenocarcinoma patients ( HR=1.47, 95% CI: 1.09-1.99). Correlation analysis showed that FAT1 mRNA expression in pancreatic adenocarcinoma was positively correlated with B-cell infiltration, CD8+ T-cell infiltration, neutrophil infiltration, macrophage infiltration, and myeloid dendritic cell infiltration ( ρ=0.27, P＜0.001; ρ=0.28, P＜0.001; ρ=0.32, P＜0.001; ρ=0.21, P=0.004; ρ=0.32, P＜0.001), and also positively correlated with mRNA expression of CD274, HAVCR2, and PDCD1LG2 ( r=0.327, P＜0.001; r=0.231, P=0.002; r=0.258, P＜0.001). GO and KEGG enrichment analyses showed that FAT1 mRNA expression levels were associated with activation of the Wnt signaling pathway ( P=0.029), the PI3K/Akt pathway ( P<0.001), and other tumor microenvironment-related pathways. (2) Validation of own tissue samples: among 192 pancreatic adenocarcinoma tissues, FAT1 was highly expressed in 58 cases (30.21%), and the proportion of FAT1-expressing positive tumor cells was positively correlated with the combined positive score of PD-L1 and the number of CD3+ T-cells infiltration ( r=0.154, P=0.032; r=0.287, P＜0.001), and the protein expression of FAT1 had no correlation with the differentiation degree of pancreatic adenocarcinoma ( ρ=0.082, P=0.254). The median OS of 58 patients in the FAT1 high-expression group and 134 patients in the FAT1 low-expression group were 18.89 and 25.84 months, respectively, and the difference was not statistically significant (χ2=1.93, P=0.165). Conclusion:FAT1 gene is highly expressed in pancreatic adenocarcinoma tissues, may play an oncogenic role in pancreatic adenocarcinoma, may be an adverse influence on overall survival and progression-free survival of patients; FAT1 gene may be involved in multiple immune-related pathways and promote tumor immune escape.

Objective:To investigate the efficacy and safety of ab externo or ab interno transluminal trabeculotomy in the treatment of secondary glaucoma following pars plana vitrectomy (PPV).Methods:An observational case series method was performed.Seventeen eyes of 17 patients with glaucoma following PPV were enrolled in Henan Eye Hospital and Beijing Tongren Hospital from May 2016 to Feburary 2022.Primary conditions of patients receiving PPV included retinal detachment in 13 eyes, vitreous hemorrhage in 3 eyes, and entophthalmia in 1 eye.All the subjects underwent ab externo (11 eyes) or ab interno (6 eyes) transluminal trabeculotomy.The scope of all cases accepted trabeculotomy was ≥300°(11 cases of 360°, 4 cases of 330° and 2 cases of 300°).Before and at 1 week, 1 month, 6 months and 12 months after surgery, the intraocular pressure (IOP) was evaluated by Goldmann Tonometer and the best corrected visual acuity (BCVA) was measured using a standard visual acuity chart and converted to logrithm of minimal angle of resolution (LogMAR).The number of anti-glaucoma drug applications and surgery-related complications were recorded.The primary outcomes evaluated were IOP and surgical success rate.Secondary outcomes were medication quantity, BCVA (LogMAR) changes, and complications.Surgical success was defined as IOP reduction to <21 mmHg (1 mmHg=0.133 kPa) with or without the use of IOP-lowering medication.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[41]).Written informed consent was obtained from each subject.Results:Preoperative, 1-week, 1-month, 6-month, and 12-month postoperative mean IOP was (34.41±5.11), (21.88±11.72), (20.77±7.67), (19.50±7.01), and (16.32±4.68)mmHg, respectively, with an statistically significant overall difference ( F=20.779, P<0.001).IOP at difference time points after surgery were lower than that before surgery, showing statistically significant differences (all at P<0.01).Compared with before surgery, IOP was reduced more than 40% at 12 months after surgery in 14 eyes.Surgical success rates at 6 and 12 months after surgery were both 76.5%.The number of IOP-lowing drugs decreased significantly after operation ( Z=-4.580, P<0.001).The difference in BCVA between before and 6 months after surgery was not statistically significant ( Z=-1.311, P=0.190).No serious complications were seen in any of the operated eyes postoperatively. Conclusions:Ab externo or ab interno transluminal trabeculotomy is safe and effective in the treatment of secondary glaucoma after PPV.

This study aims to construct C57/B6-L and A549 cell lines that stably overexpress circu-lar RNA LAMP3(circLAMP3),laying the foundation for further research on the biological func-tions of circLAMP3.Total RNA was extracted and reverse transcripted into cDNA from C57/B6-L and A549 cells to amplify the full-length sequence of circLAMP3.Then,the fragments of cir-cLAMP3 were ligated into pLC5-ciR vector to obtain pLC5-Mouse-circLAMP3 and pLC5-Human-circLAMP3 recombinant plasmids.The lentiviruses expressing circLAMP3 were packaged on tran-sient transfected HEK293T cells.C57/B6-L and A549 cells were infected with lentiviruses to gen-erate cell lines overexpressing circLAMP3 through puromycin screening.To verify the overexpres-sion efficiency of circLAMP3 of cell lines,we performed the fluorescence microscopy,PCR amplifi-cation,quantitative PCR(qPCR),and Sanger sequencing experiments.The results indicated that the overexpression plasmids of pLC5-Mouse-circLAMP3 and pLC5-Human-circLAMP3 were suc-cessfully constructed.Strong green fluorescence was observed under a fluorescence microscopy.C57/B6-L and A549 cell lines showed a significant increase in the expression of circLAMP3 by PCR and qPCR methods.Sanger sequencing results showed that the junction site of circLAMP3 was correct.This study successfully constructed C57/B6-L and A549 cell lines overexpressing circLAMP3,providing biomaterials for further exploration of the biological function of circLAMP3 in influenza virus replication.
