Objective:To develop the Nurse Parenting Stress Scale and evaluate its reliability and validity.Methods:Based on Abidin's Parenting Stress Theory, scale items were generated through literature review and semi-structured interviews. The initial version was constructed via Delphi expert consultation. Using a convenience sampling method, nurses from six hospitals in Shandong Province were surveyed between August and October 2024. The first survey collected 314 questionnaires (308 valid, effective recovery rate 98.1%) for item analysis and exploratory factor analysis (EFA). The second survey collected 458 questionnaires (447 valid, effective recovery rate 97.6%) for confirmatory factor analysis (CFA) .Results:The Nurse Parenting Stress Scale consists of 4 dimensions and 31 items. The Cronbach's α coefficient of the total scale was 0.951, split-half reliability was 0.782, and test-retest reliability was 0.926. EFA extracted four common factors explaining 70.241% of the cumulative variance. CFA demonstrated a good model fit. The item-level content validity index ( I- CVI) ranged from 0.889 to 1.000, the scale-level universal agreement content validity index ( S- CVI/ UA) was 0.903, and the scale-level average content validity index ( S- CVI/ Ave) was 0.989. Conclusions:The Nurse Parenting Stress Scale shows strong reliability and validity and can serve as an effective tool for assessing parenting stress among nurses.

Fibroblast activation protein inhibitors(FAPI)can specifically bind to fibroblast activation protein,which is highly expressed in tumor stroma,and 68Ga-FAPI do not get involved into the procedure of glucose metabolism in tumor cells.68Ga-FAPI PET/CT and PET/MR can be used for displaying malignant tumors at various sites and play a unique role for diagnosis and differential diagnosis.The research progresses of 68 Ga-FAPI-based PET/CT and PET/MR for diagnosing malignant tumors were reviewed in this article.

Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine disorders in women of reproductive age, and its pathogenesis is not yet fully understood. Many studies have confirmed that programmed cell death (PCD) can affect the occurrence and development of PCOS, and regulating PCD may be the key to prevent and treat PCOS. Recent researches have revealed many non-coding RNA (ncRNA) related to epigenetics, including microRNA, long ncRNA, and circular RNA. Although these ncRNA do not directly serve as carriers of genetic information, they can activate various cellular response mechanisms by regulating the expression of related proteins and genes, such as apoptosis, autophagy, ferroptosis, necroptosis, and pyroptosis, thereby affecting granulosa cell development, disrupting endocrine homeostasis, participating in the pathological process of PCOS, and influencing its prognosis. This paper discusses the pathogenesis of PCOS through the regulation of PCD by ncRNA, aiming to provide new insights for the treatment of PCOS.

Objective To observe the clinical efficacy of Jiangshabanxia nano-paste on nausea and vomiting in end-stage patients and its effect on the quality-of-life (QOL) in cancer patients. Methods 120 end-stage patients with nausea and vomiting symptoms above grade III were randomly divided into observation group and control group. They were treated with Jiangshabanxia nano-paste and placebo paste respectively. The paste patch was changed every 24 hours and used continuously for 7 days. The nausea and vomiting symptom score, the quality-of-life measurement score and KPS score of cancer patients in the two groups were observed to evaluate the curative effect. Results After 7 days of treatment, the symptom scores of nausea and vomiting in the observation group decreased significantly, the KPS score of the observation group increased, and the effective rate was higher than that in the control group. The score of QOL measurement showed that after treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group decreased, and the score of overall health area increased. After treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group was lower than that in the control group, and the scores of overall health area in the observation group were higher than those in the control group. Conclusion Jiangshabanxia nano-paste has a good clinical efficacy nausea and vomiting in end-stage patients, it also can improve the quality of life end-stage cancer patients.

Objective:To investigate predictive value of model based on pre-surgical 18F-FDG PET/CT metabolic parameters for mediastinal lymph node metastasis (LNM) in lung adenocarcinoma. Methods:A total of 288 patients with lung adenocarcinoma (135 males, 153 females, age (61.6±8.5) years) who diagnosed and treated in the Fourth Hospital of Hebei Medical University from January 2016 to February 2021 were enrolled retrospectively. All patients underwent 18F-FDG PET/CT examination within 1 month before operation, and underwent complete resection of primary lung tumor and standard lymph node dissection. PET/CT parameters were extracted (PET metabolic parameters: minimum SUV(SUV min), SUV max, SUV mean, SUV standard deviation (SUV std), metabolic tumor volume (MTV) and total lesion glycolysis (TLG); CT parameters: minimum CT value (HU min), maximum CT value (HU max), mean CT value (HU mean), CT value standard deviation (HU std)). Multivariate logistic regression analysis was used for screening parameters and establishing model to predict LNM. ROC curves analyses were used to evaluate the predictive performance of models. Results:Among 288 patients, 90 had LNM, and 361 metastatic lymph nodes (N1: 186, N2: 175) were reported by pathology. SUV min (odds ratio ( OR)=1.859, 95% CI: 1.074-3.220, P=0.027), SUV max ( OR=2.255, 95% CI: 1.306-3.893, P=0.004), SUV mean ( OR=0.277, 95% CI: 0.115-0.665, P=0.004) were predictors of LNM. The AUC of PET/CT model was 0.849 (95% CI: 0.804-0.893), and the sensitivity, specificity, accuracy, and positive and negative predictive values were 87.8%(79/90), 72.2%(143/198), 77.1%(222/288), 59.0%(79/134) and 92.9%(143/154), respectively. Conclusion:The model based on 18F-FDG PET/CT metabolic parameters can improve the accuracy of pre-surgical N-staging in patients with lung adenocarcinoma.

Objective:To investigate the efficacy of hemodiafiltration combined with hemoperfusion in the treatment of secondary hyperparathyroidism (SHPT) in patients undergoing maintenance hemodialysis (MHD).Methods:A total of 40 patients with SHPT undergoing MHD who received treatment at the Blood Purification Center of The First Affiliated Hospital of Anhui University of Science and Technology from February 2021 to March 2023 were included in this prospective cohort study. They were randomly divided into a control group and an observation group ( n = 20/group).The control group received a single high flux hemodialysis, while the observation group used a combination of hemodialysis filtration and hemoperfusion for 3 months. In both groups, the changes in hemoglobin, blood urea nitrogen, serum creatinine, serum calcium, serum phosphorus,and parathyroid hormone levels were compared before and after dialysis. Results:After dialysis, the hemoglobin level in the observation group was (119.45 ± 5.27) g/L, which was significantly higher than (106.30 ± 6.52) g/L in the control group ( t = -7.02, P < 0.001). The serum phosphorus level in the observation group was (1.18 ± 0.17) mmol/L, which was significantly lower than (1.52 ± 0.22) mmol/L in the control group ( t = 5.49, P < 0.001). The parathyroid hormone level in the observation group was (122.14 ± 40.57) ng/L, which was significantly lower than (168.78 ± 78.27) ng/L in the control group ( t = 2.39, P = 0.023). Conclusion:Hemodiafiltration combined with hemoperfusion can reduce clinical symptoms, increase hemoglobin level, and reduce phosphorus and parathyroid hormone levels in patients with SHPT undergoing MHD, which deserves clinical promotion.

It is recommended that medical and nursing staff identify the risk factors of PPOI in a timely and accurate manner, and actively take measures to prevent the occurrence of PPOI and reduce the incidence of PPOI in patients.

Objective:To investigate the therapeutic effect of human umbilical cord mesenchymal stem cells (MSCs) on psoriasis-like mouse models induced by imiquimod and the underlying mechanisms.Methods:Eighteen C57BL/6 mice were randomly and equally divided into vaseline group, model group and treatment group according to a random number table. The mice in the model group and treatment group received topical treatment with 5% imiquimod cream at a dose of 62.5 mg once a day for 6 consecutive days on the shaved back, and those in the vaseline group received the treatment with the same amount of vaseline ointment; the mice in the treatment group were injected with 1.5×10 6 human umbilical cord MSCs via the caudal vein on days 1 and 4. The severity of skin lesions on the back of the mice was assessed everyday according to the psoriasis area and severity index (PASI) . Twenty-four hours after the last treatment, that is, on day 7, blood samples were taken, and the mice were sacrificed. The dorsal skin tissues were resected and subjected to hematoxylin and eosin (HE) staining. A single cell suspension of the resected spleen was prepared, and flow cytometry was performed to detect the Th1 and Th17 cell subsets in the spleen cells. Enzyme-linked immunosorbent assay was conducted to detect serum levels of cytokines interleukin (IL) -17A and tumor necrosis factor (TNF) -α. One-way analysis of variance was used for comparisons among groups, Tukey test for multiple comparisons, and repeated measures analysis of variance for the analysis of changes in the PASI score over time. Results:On day 7, there was obvious scaly erythema on the back of the mice in the model group, and the skin thickness and number of infiltrating inflammatory cells were significantly higher in the model group (78.73 ± 23.11 μm, 36.16 ± 2.95 cells/mm 2) than in the vaseline group (13.28 ± 4.57 μm, 13.33 ± 1.15 cells/mm 2, q=19.25, 7.21, respectively, both P < 0.001) . The treatment group showed significantly decreased PASI score, epidermal thickness and number of infiltrating inflammatory cells compared with the model group (all P < 0.001) . The percentage of Th17 cell subsets in the spleen cells and serum level of TNF-α were significantly lower in the treatment group than in the model group (both P < 0.05) . There were no significant differences in the spleen weight, spleen index, spleen cell count, Th1 cell percentage or serum IL-17A level between the treatment group and the model group (all P>0.05) . Conclusion:Human umbilical cord MSCs can effectively alleviate skin inflammation induced by imiquimod in the psoriasis-like mouse models, likely by inhibiting Th17 cell formation and TNF-α expression.
