Objective: To explore the influence of group psychological counseling on the mental health of children with mother s authoritarian parenting. Methods: From November 2022 to February 2023, 76 students from grades 4 to 6 whose mother showed authoritarian parenting style, while fathers adopted no authoritative, authoritarian or democratic parenting style and who scored ≥65 on the total MHT were selected using the Parenting Style Questionnaire (PBI) and the Mental Health Diagnostic Test (MHT). All the participants and their mothers were randomly assigned to the intervention and control groups. Before and after the intervention, participants filled out questionnaires on parental bonding instrument and mental health test. Control group: regular delivery of mental health education information, 2 times per week, for 8 weeks, without any other intervention. Intervention group: group counseling activities were conducted once a week. Each intervention lasted 1.5-2 hours and lasts for 8 weeks. Before and after the intervention, participants filled in the family parenting style and mental health screening questionnaires. Results: After the intervention, compared with the control group, students in the intervention group showed a significant decrease in the total scale score of the MHT, learning anxiety, social anxiety, allergic tendency, physical symptoms, fear tendency, and impulsive tendency ( t=-0.43, -1.04 , -0.81, P >0.05). After intervention, the intervention group students showed a significant decrease in psychological diagnosis test scores, learning anxiety, anxiety towards others, allergic tendencies, physical symptoms, phobic tendencies, and impulsive tendencies compared to the control group students ( t=-20.00, -5.06, -2.09, -3.36, -6.15, -4.76, -5.15, P <0.05). Conclusion Rregular group psychological counseling can effectively improve the academic anxiety, social anxiety, allergic tendencies, physical symptoms, fearful and impulsive tendencies of students whose mothers with authoritarian parenting style, and greatly improve their mental health.

Objective To discover new-structure active molecules in order to provide candidate compounds for anti-radiation drug research.Methods Conformational fixation and functional group conversion strategies were used to modify the structure of Ex-RAD before substituted 2H-benzopyran-3-formylaniline compounds were designed and synthesized.The anti-radiation activities of the synthesized compounds were screened via irradiated cell survival models and the cytotoxicity of the active compounds was examined.Western blotting assay was used to investigate the effects of the optimal compound on the expressions of apoptosis related proteins in irradiated cells.The anti-radiation activity of the optimal compound was evaluated through irradiated mice models.Results Twenty-one target compounds were synthesized,eight of which were found to significantly improve the survival of irradiated cells.Four compounds were selected for re-screening and cytotoxicity evaluation.Compound D19 was determined as the optimal compound that could affect the expressions of apoptosis related proteins in irradiated AHH-1 cells by Western blotting assay.Compared with the radiation group,the 30-day survival rate of D19 treated mice irradiated with 8.6 Gy of whole-body radiation increased by 70%.D19 showed protective effect on the blood system of non-lethal dose irradiated mice.Conclusion The novel compound D19 has shown strong anti-radiation activity and deserves more research.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Guillain-Barré syndrome(GBS)is an immune-mediated acute inflammatory peripheral neuropathy.It primarily manifests as acute,symmetrical,flaccid paralysis of multiple nerve roots and peripheral neuropathy,with or without cranial nerve involvement.The two most common subtypes of GBS are acute inflammatory demyelinating polyneu-ropathy(AIDP)and acute motor axonal neuropathy(AMAN).Other less common types include acute motor sensory axo-nal neuropathy(AMSAN)and Miller-Fisher syndrome(MFS).In addition,other variants,such as pharyngeal-cervical-brachial variant,multiple cranial neuropathy,and paraplegia,have been increasingly reported.Therefore,GBS is gradu-ally being recognized as a spectrum of diseases.Previous studies have found and confirmed that ganglioside antibodies are associated with GBS,including anti-GM1,anti-GM2,anti-GM3,anti-GM4,anti-GD1a,anti-GD1b,anti-GT1a,anti-GT1b,and anti-GQ1b antibodies.However,GBS with a sensory level has been rarely reported.This report presents a case of anti-GM4 IgM-positive GBS with a sensory level following gastrointestinal surgery,which has not been previously reported.The findings of this study may help enhance awareness of this disease and reduce misdiagnosis.

Objective To investigate the sleep structure of Parkinson's disease (PD) patients with rapid eye movement sleep behavior disorder (RBD) and its correlations with cognitive function, depressive state and motor function. Methods A total of 120 PD patients were enrolled in this study, and divided into PD+RBD group (n=45) and PD group (n=75) based on the presence or absence of RBD. Sleep structure was recorded for both groups. The scores of the Montreal Cognitive Assessment (MoCA), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Unified Parkinson's Disease Rating Scale Part Ⅲ (UPDRS-Ⅲ) and Scales for Outcomes in Parkinson's Disease-Autonomic (SCOPA-AUT) were compared between the two groups. The correlations of MoCA, HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores with sleep structure in the PD+RBD group were analyzed. Results The PD+RBD group showed significantly higher percentage of non-rapideye movement (NREM) at stage 1, arousal index, periodic limb movements during sleep (PLMS) and apnea-hypopnea index (AHI) compared to the PD group, while the percentages of NREM at stage 3, rapid eye movement (REM) sleep, sleep efficiency and lowest oxygen saturation were significantly lower (P < 0.05). The PD+RBD group also had significantly higher HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores, and significantly lower MoCA scores compared to the PD group (P < 0.05). In the PD+RBD group, the percentages of NREM at stage 1, arousal index, PLMS and AHI were positively correlated with HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores, and negatively correlated with MoCA scores (P < 0.05). Conversely, the percentages of NREM at stage 3, REM sleep, sleep efficiency and lowest oxygen saturation were negatively correlated with HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores, and positively correlated with MoCA scores (P < 0.05). Conclusion PD patients with RBD exhibit disrupted sleep structure, which is closely associated with cognitive function, depressive state, motor function, and autonomic nervous system function.

Background Research on the relationship between ambient temperature and preterm birth has received increasing attention, but the conclusions of the previous literature are inconsistent. Objective To explore the impact of environmental temperature exposure in Ningbo on premature delivery of pregnant women. Methods The birth information, preterm birth data, and age of pregnant women from January 2016 to September 2020 were collected by the electronic medical record system of Ningbo Women’s and Children’s Hospital. Meteorological data for the same period were obtained through Ningbo Meteorological Bureau, including daily average temperature, daily average relative humidity, and daily average air pressure. Daily concentrations of SO₂, NO₂, and PM₁₀ were derived through the air quality real-time release system on the website of Ningbo Environmental Protection Bureau. A distributed lag nonlinear model was used to analyze the impact of environmental temperature on preterm birth by stratifying pregnant women’s age and birth delivery mode. Results The incidence rate of preterm birth in Ningbo from 2016 to 2020 was 5.91%. The exposure-response curve between environmental temperature and preterm birth presented a “U” shape. Taking 22.5 ℃ as a reference, the cumulative effect of 31 ℃ (the 95th percentile) and 32 ℃ (the 99th percentile) over a 21-day lag on preterm delivery was statistically significant, and the related RR (95%CI) values were 1.67 (1.05-2.65) and 1.85 (1.09-3.14) respectively. The results of stratified analysis showed that among pregnant women ≥30 years old, the 21-day cumulative effects of 31 ℃ and 32 ℃ on preterm delivery were statistically significant, and the related RR (95%CI) values were 2.09 (1.08-4.05) and 2.36 (1.11-5.03) respectively; among pregnant women with natural delivery, the 21-day cumulative effect of 32 ℃ on preterm delivery was statistically significant, and the RR (95%CI) was 1.95 (1.02-3.74). Conclusion Exposure of pregnant women to high temperature during pregnancy could increase the risk of preterm birth, and there is a delayed cumulative effect.

ObjectiveTo explore the effective components， targets， and mechanism of Houttuynia cordata against lung cancer by means of systems pharmacology and further to provide a reference for the further development and clinical application of this medicinal. MethodChemical components of H. cordata were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the active components were screened based on oral bioavailability （OB） and drug-likeness （DL）. Then the potential targets were predicted， followed by enrichment analysis. Finally， sodium houttuyfonate （SH） was selected for verifying the anti-tumor mechanism. Cell counting kit-8 （CCK-8） assay was used to evaluate the effect of SH on the in vitro proliferation of two lung cancer cell lines： A549 and LLC， and the regulation of tumor-related proteins by SH was verified by Western blot. ResultA total of 7 active compounds and 352 targets of the active components were screened out. According to the enrichment analysis of targets， H. cordata had potential therapeutic effects on cancer. SH had inhibitory effect on both A549 and LLC. Western blot results showed that G₁/S-specific Cyclin D₁， E₁ and cyclin-dependent kinase （CDK）2， CDK4 all tended to be down-regulated， and Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） also changed significantly. ConclusionH. cordata has the potential anti-tumor effects by arresting the tumor cells in the G₁ phase through the JAK2/STAT3 pathway.

Background and Objectives: Psoriasis is a chronic inflammatory skin disease, which the mechanisms behind its initiation and development are related to many factors. DMSCs (dermal mesenchymal stem cells) represent an important member of the skin microenvironment and play an important role in the surrounding environment and in neighbouring cells, but they are also affected by the microenvironment. We studied the glucose metabolism of DMSCs in psoriasis patients and a control group to reveal the relationship among glucose metabolism, cell proliferation activity，and VEC (vascular endothelial cell) differentiation in vitro, we demonstrated the biological activity and molecular mechanisms of DMSCs in psoriasis. Methods: and Results: We found that the OCR of DMSCs in psoriatic lesions was higher than that in the control group, and mRNA of GLUT1 and HK2 were up-regulated compared with the control group. The proliferative activity of DMSCs in psoriasis was reduced at an early stage, and mRNA involved in proliferation, JUNB and FOS were expressed at lower levels than those in the control group. The number of blood vessels in psoriatic lesions was significantly higher than that in the control group (p＜0.05), which the mRNA of VEC differentiation, CXCL12, CXCR7, HEYL and RGS5 tended to be increased in psoriatic lesions compared to the control group, in addition to Notch3. Conclusions We speculated that DMSCs affected local psoriatic blood vessels through glucose metabolism, and the differentiation of VECs, which resulted in the pathophysiological process of psoriasis.

Astragali radix(AR,the dried root of Astragalus)is a popular herbal remedy in both China and the United States.The commercially available AR is commonly classified into premium graded(PG)and ungraded(UG)ones only according to the appearance.To uncover novel sensitive and specific markers for AR grading,we took the integrated mass spectrometry-based untargeted and targeted metabolomics ap-proaches to characterize chemical features of PG and UG samples in a discovery set(n=16 batches).A series of five differential compounds were screened out by univariate statistical analysis,including arginine,calycosin,ononin,formononetin,and astragaloside Ⅳ,most of which were observed to be accumulated in PG samples except for astragaloside Ⅳ.Then,we performed machine learning on the quantification data of five compounds and constructed a logistic regression prediction model.Finally,the external validation in an independent validation set of AR(n=20 batches)verified that the five com-pounds,as well as the model,had strong capability to distinguish the two grades of AR,with the pre-diction accuracy＞90％.Our findings present a panel of meaningful candidate markers that would significantly catalyze the innovation in AR grading.

Objective:To explore the application effect of segmented teaching combined with Kirkpatrick model evaluation in the teaching of specialized nurses of peripherally implanted central venous catheter (PICC).Methods:A total of 60 trainees in the PICC specialized nurse training class in PICC Clinic of Cancer Hospital Affiliated to Nantong University from June 2020 to September 2020 were selected in the study, and they were randomly divided into a control group and a study group, with 30 nurses in each group. The control group conducted traditional training for PICC specialized nurses, and the research group used segmented teaching. After training, the Kirkpatrick model was used to evaluate the response level, learning level, behavior level and result level of the training effect of the two groups of PICC specialized nurses. SPSS 22.0 was used for t test and chi-square test. Results:Through the segmented teaching training, the evaluation results of the Kirkpatrick model showed that the effect of the PICC specialized nurse training was significantly better in the study group than that in the control group in terms of response level, learning level, behavior level and result level. The study group's satisfaction with the training program and teaching content scored higher than that of the control group, with statistically significance ( P<0.001). The research group nurses' mastery of theoretical knowledge and practical skills and humanistic care scores were higher than those of the control group, with significant differences ( P<0.001). After the training, the self-behavior assessment scores of the two groups increased, and the improvement of the research group was more obvious. When the nurses of the research group returned to the hospital clinical work after training, their professional identity, PICC teaching and guidance ability, treatment, nursing service quality, the recognition of patient and family members and the effectiveness of the department were improved to varying degrees, the corresponding measures could be carried out in the hospital, and the development of PICC technology was promoted. Conclusion:The combination of segmented teaching and Kirkpatrick model evaluation can effectively meet the training needs of PICC specialized nurses and make a full range of effect evaluations to improve the quality of PICC specialized nursing services.
