Objective:To explore the latent profile characteristics of fatigue in patients with non-small cell lung cancer (NSCLC) complicated by radiation-induced pulmonary fibrosis (RIPF), and to provide evidence for developing precision nursing strategies.Methods:A convenience sample of 120 patients with RIPF and NSCLC who received treatment at the First Affiliated Hospital of Zhengzhou University between January 2022 and December 2023 was recruited. Baseline demographic and clinical data and the Multidimensional Fatigue Inventory (MFI) were collected. Latent profile analysis (LPA) was performed to classify fatigue levels, and multinomial logistic regression was used to identify influencing factors. A total of 120 questionnaires were distributed, and 116 valid responses were obtained, with a valid response rate of 96.67% (116/120) .Results:LPA identified three latent classes of fatigue among the 116 patients: the physiological-cognitive compound fatigue group ( n=52), the emotional-sleep disturbance group ( n=38), and the mildly adaptive group ( n=26). Multinomial logistic regression revealed that age, Eastern Cooperative Oncology Group performance status (ECOG-PS), Karnofsky Performance Status (KPS), sleep quality, and anxiety were significant factors associated with the physiological-cognitive compound fatigue group ( P<0.05). Sleep quality, anxiety, depression, pain, and KPS were significant factors associated with the emotional-sleep disturbance group ( P<0.05) . Conclusions:Patients with RIPF and NSCLC can be classified into three subtypes of fatigue. Differentiated nursing strategies should be developed accordingly to achieve precise and individualized interventions.

The purpose of this study was to investigate the intervention effect and mechanism of Lycium barbarum leaves on letrozole-induced polycystic ovary syndrome (PCOS) mice. The PCOS model was prepared by letrozole combined with high-fat diet. After successful modeling, 40 mice were randomly divided into PCOS group, positive drug metformin group, low-dose Lycium barbarum leaves group, and high-dose Lycium barbarum leaves group. The corresponding drugs were given by gavage for 29 days. At the end of the experiment, the eyeballs were removed for blood collection and ovarian tissue was collected. The ovarian mass, fasting blood glucose (FBG), fasting insulin (FINS), testosterone (T), anti-Mullerian hormone (AMH), luteinizing hormone (LH), follicle stimulating hormone (FSH), and estradiol (E₂) levels were measured in each group. The morphology of ovarian tissue was observed by hematoxylin-eosin staining, and the oocytes, cystic follicles and corpus luteum were counted. Cecal contents of mice were collected for analysis of intestinal flora composition and differential flora. The animal experiment process was approved by the Animal Ethics Committee of Nanjing University of Traditional Chinese Medicine. The results showed that the estrous cycle of PCOS mice was disordered. Compared with the PCOS group, the Lycium barbarum leaves group can significantly reduce the ovarian damage of mice, reduce the number of cystic dilated follicles, and normalize the estrous cycle. After the intervention of Lycium barbarum leaves, the levels of FBG, FINS, T, AMH, LH, FSH and LH/FSH were significantly decreased (P < 0.05), while the level of E₂ was significantly increased (P < 0.001). In addition, Lycium barbarum leaves can regulate the disorder of intestinal flora diversity in PCOS mice, increase the abundance of Bacteroidetes, and reduce the abundance of Firmicutes, Ileibacterium, Romboutsia and Faecalibaculum. In summary, Lycium barbarum leaves can play a therapeutic role in PCOS mice by improving insulin resistance, regulating reproductive hormone disorders and gut microbiota imbalance. It provides scientific basis and useful reference for the rational utilization and development of Lycium barbarum leaves.

Objective:To summarize the imaging characteristics of primary intestinal lymphoma (PIL).Methods:As a cross-sectional study, a total of 103 consecutive patients diagnosed as PIL by pathology were retrospectively enrolled at Affiliated Shandong Provincial Hospital of Shandong First Medical University between January 2013 to December 2023. Ninety-four patients underwent CT plain and enhanced scans, and the remaining 9 patients only underwent MRI examination. Imaging features were evaluated, including the location and shape of the tumor, the shape of the intestinal wall and lumen, abdominal lymph nodes, the density or signal intensity of the tumor, and the degree and mode of enhancement after the enhancement scan.Results:The most frequent location of PIL was the ileum (43.7%, 45/103), followed by the ascending colon (20.4%, 21/103). Ninety-one patients had a single lesion (88.3%), while the other 12 patients had multiple lesions (11.7%). Diffuse large B-cell lymphoma was the most common histopathological type of the PIL (65.0%, 67/103), followed by mucosa-associated lymphoid tissue lymphoma (9.7%, 10/103). Generally, PIL classically presented intestinal wall thickening (81.6%, 84/103) and exophytic mass (28.2%, 29/103). Aneurysmal dilatation of the lumen appeared in 19 patients. Nineteen tumors (18.4%) grew out of the lumen, and perforation was shown in 3 patients. Bulky mesenteric or retroperitoneal adenopathy occurred in 28 patients (27.2%). Seventy-two tumors (69.9%) showed homogeneous enhancement, and 75 (72.8%) showed mild-to-moderate enhancement. In DWI images, all 9 tumors showed significant diffusion limitation.Conclusions:The most frequent location of PIL was the ileum. The main imaging characteristics were segmental intestinal wall thickening, which showed mild-to-moderate homogeneous enhancement and restricted diffusion.

This paper explored the protective effect and potential mechanism of Shouhui Tongbian Capsules(SHTB) on cerebral ischemia-reperfusion rat models. Rats were randomly divided into sham surgery group, model group, low-dose SHTB group(0.2 g·kg~(-1)·d~(-1)), high-dose SHTB group(SHTB g·kg~(-1)·d~(-1)), and an edaravone positive drug group(5.4 mg·kg~(-1)·d~(-1)), with 12 rats in each group. Rats were given continuous intragastric administration seven days before surgery, and the suture method was used to establish the cerebral ischemia-reperfusion injury(CIRI) rat model. Zea-Longa rating scale for neurological functions was used to assess the degree of neurological function impairment in rats; hematoxylin-eosin(HE) staining was used to observe the pathological damage of rats' brain tissue; TTC staining was used to measure the area of cerebral infarction in rats; enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of interleukin-6(IL-6), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α) in each group. Western blot was used to detect the level of tight junction protein associated with the blood-brain barrier and intestinal barrier, as well as the protein expression of the TLR4/MyD88/NF-κB pathway in brain tissue. Changes in rats' brain tissue and metabolites in serum were detected by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS), so as to explore the potential mechanism of SHTB treatment for CIRI in rats. Compared with the model group, SHTB could significantly alleviate the pathological damage to the brain of CIRI rats, reduce the volume of cerebral infarction, and lower the level of inflammation in the serum; Western blot results showed that SHTB could regulate the expression of tight junction proteins related to the blood-brain barrier and intestinal barrier in CIRI rats and downregulate the expression of TLR4, NF-κB, and MyD88 proteins in brain tissue. The UPLC-MS/MS results indicated that SHTB could significantly regulate the content of potential differential metabolites such as fatty acids, and serum and brain tissue are involved in pathways such as unsaturated fatty acid biosynthesis. SHTB could repair intestinal barrier function, reduce inflammation levels in the body, and improve the damaged blood-brain barrier, exerting a protective effect on brain nerves. Its mechanism may be achieved by balancing fatty acid metabolism and regulating the expression of TLR4/MyD88/NF-κB signaling pathway proteins.

Objective: To evaluate the effect of depth of remission of induction chemotherapy on the overall prognosis of limited stage small cell lung cancer (L-SCLC). Methods: The study was a retrospective, L-SCLC patients who contained complete imaging data and underwent consecutive standardized treatments at the Department of Thoracic Radiation and Medical Oncology, Zhongnan Hospital of Wuhan University between January 2013 and June 2021 were included. To delineate the volume of tumor before and after induction chemotherapy and to calculate the depth of remission caused by the induced chemotherapy. The time receiver operating characteristic (timeROC) method was used to determine the optimal predictors for prognosis, multi-factor analysis using Cox risk proportional model. Results: A total of 104 patients were included in this study. The median PFS and OS of this cohort were 13.7 months and 20.9 months, respectively. It was observed by timeROC analysis that residual tumor volume after induction chemotherapy had the optimal predictive value of PFS at 1 year (AUC=0.86, 95% CI: 0.78~0.94) and OS at 2 years (AUC=0.76, 95% CI: 0.65~0.87). Multivariate analysis showed residual tumor volume after induction chemotherapy was the independent prognostic factor to PFS (HR=1.006, 95% CI: 1.003~1.009, P<0.01) and OS (HR=1.009, 95% CI: 1.005~1.012, P<0.001). For those whose residual tumor volume remitted to less than 10 cm(3) after induction chemotherapy, the favorable long-term outcomes could be achieved, regardless of their initial tumor load. Conclusion: The depth of remission of induction chemotherapy could be a promising prognostic predictor to the L-SCLC and provide the individualized treatment guidance.

BACKGROUND: Pneumonia-like primary pulmonary lymphoma (PPL) was commonly misdiagnosed as infectious pneumonia, leading to delayed treatment. The purpose of this study was to establish a computed tomography (CT)-based radiomics model to differentiate pneumonia-like PPL from infectious pneumonia. METHODS: In this retrospective study, 79 patients with pneumonia-like PPL and 176 patients with infectious pneumonia from 12 medical centers were enrolled. Patients from center 1 to center 7 were assigned to the training or validation cohort, and the remaining patients from other centers were used as the external test cohort. Radiomics features were extracted from CT images. A three-step procedure was applied for radiomics feature selection and radiomics signature building, including the inter- and intra-class correlation coefficients (ICCs), a one-way analysis of variance (ANOVA), and least absolute shrinkage and selection operator (LASSO). Univariate and multivariate analyses were used to identify the significant clinicoradiological variables and construct a clinical factor model. Two radiologists reviewed the CT images for the external test set. Performance of the radiomics model, clinical factor model, and each radiologist were assessed by receiver operating characteristic, and area under the curve (AUC) was compared. RESULTS: A total of 144 patients (44 with pneumonia-like PPL and 100 infectious pneumonia) were in the training cohort, 38 patients (12 with pneumonia-like PPL and 26 infectious pneumonia) were in the validation cohort, and 73 patients (23 with pneumonia-like PPL and 50 infectious pneumonia) were in the external test cohort. Twenty-three radiomics features were selected to build the radiomics model, which yielded AUCs of 0.95 (95% confidence interval [CI]: 0.94-0.99), 0.93 (95% CI: 0.85-0.98), and 0.94 (95% CI: 0.87-0.99) in the training, validation, and external test cohort, respectively. The AUCs for the two readers and clinical factor model were 0.74 (95% CI: 0.63-0.83), 0.72 (95% CI: 0.62-0.82), and 0.73 (95% CI: 0.62-0.84) in the external test cohort, respectively. The radiomics model outperformed both the readers' interpretation and clinical factor model ( P <0.05). CONCLUSIONS The CT-based radiomics model may provide an effective and non-invasive tool to differentiate pneumonia-like PPL from infectious pneumonia, which might provide assistance for clinicians in tailoring precise therapy.

ObjectiveTo explore the application of Brain and Spinal Injury Center (BASIC) score in evaluation of traumatic cervical spinal cord injury. MethodsFrom January, 2015 to December, 2021, 175 patients with traumatic cervical spinal cord injury in Beijing Bo'ai Hospital were analyzed. Gender, age, cause of injury, injury mechanism and American Spinal Injury Association Impairment Scale (AIS) grade were collected. The sagittal and axial T₂ weighted imaging (T₂WI) of the patients were evaluated with BASIC score, single/multi-segment injury, and with/without intramedullary hemorrhage. According to the injury mechanism, the patients were divided into two groups: with fracture/fracture dislocation (n = 92) and without fracture and dislocation (n = 83). The baseline demographic indicators and T₂WI evaluation indicators were compared between the two groups, and the relationship between AIS grade and BASIC score, intramedullary hemorrhage, single/multi-segment injury were investigated. ResultsThere were significant differences in gender, age and AIS grade, BASIC score, and the rates of inntramedullary hemorrhage and single segment injury of T₂WI between two groups (t = -10.276, χ² > 8.703, P < 0.01); however, no difference was found in the cause of injury (P > 0.05). The AIS grade was significantly correlated with the BASIC score (r = 0.790, P < 0.001). There was significant difference in AIS grade between intramedullary hemorrhage or not, and single/multi-segment injury (χ² > 5.516, P < 0.05). ConclusionThe BASIC score of T₂WI is a predictor of the severity of spinal cord injury after traumatic cervical spinal cord injury, and is different with the injury mechanisms.

The AP2/ERF gene family is one of the largest transcription factor families in the plant kingdom, and plays an important role in response to biological and abiotic stresses, plant hormone responses, and plant growth and development. In this study, the AP2/ERF family of Panax notoginseng was identified by bioinformatics methods, and the physicochemical properties, structure, phylogenetic relationship, expression pattern and function of PnDREB4 gene of the family were analyzed. The results showed that 140 AP2/ERF family members were identified in P. notoginseng, which were divided into DREB, ERF, AP2, RAV and Sololit subgroups. The physicochemical properties and motifs of proteins were similar among the subgroups. There were 34 differentially expressed genes in the AP2/ERF family of Fusarium oxysporum infected P. notoginseng plants, and 19 genes were up-regulated. The expression level of PnDREB84 was up-regulated with the extension of Fusarium oxysporum infection time in the range of 0-96 h. The content of ABA and SA in P. notoginseng plants overexpressing PnDREB84 gene increased after 4 ℃ stress. The results showed that PnDREB84 gene plays a dual regulatory role in the process of biological stress and abiotic stress. PnDREB84 gene can be used as a potential molecular marker for the breeding of new varieties of P. notoginseng. The identification of AP2/ERF transcription factor and function analysis of PnDREB84 gene of P. notoginseng provided data support for the analysis of stress resistance mechanism of P. notoginseng and the breeding of new varieties.
