Objective:To explore the chain mediation effects of psychological resilience and fear of falling on family function and rehabilitation exercise adherence among stroke patients of different genders.Methods:Totally 298 stroke patients from Xinxiang Central Hospital between January and December 2023 were selected by convenience sampling. Participants were assessed using the Family Assessment Device (FAD), Connor-Davidson Resilience Scale (CD-RISC), Fear of Falling Questionnaire-Reversed (FFQ-R), and Exercise Adherence Questionnaire (EAQ). The SPSS PROCESS macro was utilized to test the chain mediation effects.Results:Male stroke patients had higher total FAD scores, communication, and family role dimension scores, total CD-RISC scores, resilience and self-reliance dimension scores, and EAQ scores, including adherence to physical exercise and exercise supervision, compared to female patients ( P<0.05). However, female patients scored higher in emotional response and emotional involvement dimensions of FAD, total FFQ-R, and all dimensions of FFQ-R, as well as adherence to seeking timely advice of EAQ ( P<0.05). Mediation analysis showed that in male stroke patients, family function had no significant direct effect on rehabilitation exercise adherence (95% CI: -0.055 - 0.096), with psychological resilience and fear of falling playing a fully mediating role; the total mediation effect was 0.113, accounting for 84.96% of the total effect. In female stroke patients, family function had a significant direct effect on rehabilitation exercise adherence, with an effect of 0.110, accounting for 42.80% of the total effect. In addition, psychological resilience and fear of falling partially mediated the relationship between family function and rehabilitation exercise adherence, with a total mediation effect of 0.147, accounting for 57.20% of the total effect. Conclusions:The levels of family function, psychological resilience, fear of falling, and rehabilitation exercise adherence, as well as the mechanisms linking these factors, differ by gender in stroke patients. In male stroke patients, psychological resilience and fear of falling fully mediate the relationship between family function and rehabilitation exercise adherence. In female stroke patients, family function influences rehabilitation exercise adherence through both direct effects and the partial mediating effects of psychological resilience and fear of falling.

ObjectiveTo observe the effect of Coptidis Rhizoma and Ophiopogonis Radix on renal tissue injury and epidermal growth factor receptor （EGFR）/phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway in rats with diabetic nephropathy （DN） and explore its possible mechanism of delaying DN. MethodThirty-six male Wistar rats were randomly divided into a normal group （6 rats） and a model group （30 rats）. The model group was fed with a high-fat and high-sugar diet combined with streptozotocin （STZ） to establish a rat model of type 2 diabetes. After the successful preparation of the model， the rats were randomly divided into the model group， low， medium， and high dose groups of Coptidis Rhizoma and Ophiopogonis Radix （100， 200， 400 mg·kg^-1）， and metformin group （200 mg·kg^-1）. After administration， the levels of fasting blood glucose （FBG）， 24 h urine protein （24 h-UTP）， creatinine （SCr）， urea nitrogen （BUN）， and uric acid （UA） were detected. Hematoxylin-eosin （HE） staining and Masson staining were used to observe the pathological changes of renal tissue in rats. Western blot and Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） were used to detect the related protein expression of EGFR， PI3K， and Akt and their mRNA expression levels in the renal tissue of rats in each group. ResultsCompared with the normal group， the levels of FBG， SCr， BUN， UA， 24 h-UTP， and kidney index in the model group were significantly increased （P<0.01）， most renal tubular epithelial cells were necrotic， and the content of collagen in glomeruli was significantly increased （P<0.01）. Compared with the model group， the above indexes of rats in each administration group were improved to varying degrees. The FBG， SCr， BUN， UA， 24 h-UTP， and kidney index of rats in each dose group and metformin group were significantly decreased （P<0.01， P<0.05）. The necrosis degree of renal tubular epithelial cells was reduced， and the fibrosis area was decreased （P<0.01）. There related protein and mRNA expressions of EGFR， PI3K， and Akt were significantly increased （P<0.05， P<0.01）. ConclusionCoptidis Rhizoma and Ophiopogonis Radix can alleviate renal tissue injury in rats with DN， and their mechanism may be related to the regulation of the EGFR/PI3K/Akt signaling pathway.

Objective:To explore the mediating effect of empathy between personality traits and death attitude in nursing students.Methods:From April to May 2022, a total of 237 undergraduate nursing students were surveyed by general information questionnaire, big five inventory, Jefferson scale of empathy for nursing students, and death attitude profile-revised. Common method bias test, correlation analysis and descriptive analysis were conducted by SPSS 26.0 software.PROCESS macro program was used to test the mediating effect.Results:Agreeableness(32.78±4.92), empathy(110.03±16.83)were positively correlated with positive death attitude(57.95±12.35)( r=0.274, 0.571, both P<0.01), neuroticism(23.00±4.78)was positively correlated with negative death attitude(31.81±10.04)( r=0.199, P<0.01), empathy was negatively correlated with negative death attitude ( r=-0.226, P<0.01). Empathy partially mediated the relationship between neuroticism and negative death attitude, the mediating effect accounted for 16.08%(0.032/0.199) of the total effect, and empathy played a completely mediating role between the agreeableness and positive death attitude. Conclusion:The death attitude of undergraduate nursing students is mainly natural acceptance. Personality traits can directly affect death attitude and also indirectly affect death attitude through empathy.

Objective:To evaluate the efficacy and tolerability of crisaborole 2% ointment in the treatment of childhood atopic dermatitis (AD) at the early stage, and to compare the efficacy of every-other-day (Qod) regimen versus twice-a-week (Biw) regimen against recurrence in the remission stage of AD.Methods:A multicenter, randomized, open-label clinical trial was conducted. Totally, 150 children with mild to moderate AD aged 2 - < 18 years were enrolled from 6 hospitals (including Beijing Children′s Hospital, Capital Medical University, etc), and randomly divided into the Qod group (76 cases) and the Biw group (74 cases). In the acute stage of AD, both groups were treated with topical crisaborole 2% ointment on skin lesions twice a day for 2 - 4 weeks, as well as with emollients throughout the whole body. The improvement of early clinical symptoms was evaluated, and the occurrence of adverse reactions was recorded in the follow up. Once the investigator′s static global assessment (ISGA) scores decreased to 1 point or less, the patient would be enrolled into the remission stage. In the remission stage of AD, patients in the Qod group and Biw group were treated with crisaborole ointment every other day and twice a week respectively; the recurrence rate of AD in the remission stage was evaluated, as well as the severity of skin lesions, itching, life quality, and the occurrence of adverse reactions at weeks 4, 8, and 12. Statistical analysis was carried out with SPSS 23.0 software by using t test for comparisons of normally distributed continuous data between two groups, Mann-Whitney U test for non-normally distributed data, chi-square test for enumeration data, and Kaplan-Meier method for analysis of survival rates. Results:A total of 142 patients were enrolled in the modified intention-to-treat population, including 71 in the Qod group and 71 in the Biw group. In the acute stage of AD, the improvement of itching and skin lesions self-reported by the children or their family members occurred on days 1.9 (1.0, 3.0) and 2.0 (1.0, 4.1) after the application of crisaborole ointment, respectively. At the end of treatment in the acute stage, 89 children (62.7%) achieved ISGA 0/1 and successfully transferred into the remission stage. The follow-up in the remission stage was completed in 83 patients (44 in the Qod group and 39 in the Biw group). In addition, recurrence occurred in 19 (43.2%) and 12 (30.8%) patients in the Qod group and Biw group respectively, and there was no significant difference in the recurrence rate between the two groups ( χ2 = 1.36, P = 0.243) ; the average time to recurrence was 64.25 (95% CI: 53.33 - 75.17) days and 75.78 (95% CI: 65.46 - 86.10) days in the Qod group and Biw group respectively. Among the patients who were in the remission stage and had not yet experienced relapse at weeks 4, 8, and 12, there were no significant differences in the eczema area and severity index (EASI) scores, ISGA scores, pruritus numerical rating scale (NRS) scores, or quality-of-life scores between the two groups (all P > 0.05) at any time points, except for the ISGA scores at week 12 (Biw group: 0 [0, 1] point vs. Qod group: 1 [0, 1] point; Z = -2.31, P = 0.021). A total of 146 patients were enrolled in the safety set. During the study period, 70 adverse events occurred in 65 patients, with an incidence rate of 44.5%, and all were mild or moderate adverse events; 55 (37.7%) patients experienced discomfort at the medication site, which mainly referred to pain (45 cases, 30.8%) and mostly occurred in the tender and skinfold areas. Conclusions:Crisaborole 2% ointment could effectively relieve clinical symptoms in children with mild to moderate AD in the early stage, and intermittent treatment could continuously relieve clinical symptoms in the remission stage. The common adverse reaction was discomfort at the application site in the early stage of AD. There was no significant difference in the impact on AD recurrence in the remission stage between the Qod regimen and Biw regimen.

Objective:To develop a nomogram model for screening of type 2 diabetes mellitus in a community population.Methods:From October to December, 2020, 6 028 community residents who participated in the " national health physical examination" in Karamay community with complete physical examination data and met the inclusion and exclusion criteria were selected. The physical examination data included medical history, physical examination, laboratory, and ultrasound reports. Random segmentation sampling was used to divide the population into modeling and validation cohorts, and LASSO regression analysis was used to screen for independent factors associated with diabetes diagnosis. The independent influencing factors were furthor incorporated into the multi-factor logistic regression, and the RMS software package was used to construct the column chart. The area under receiver operating characteristic(ROC) curve was used to measure the differentiation of the model. The calibration curve can directly reflect the calibration degree of the model.Results:In the modeling group, multivariate logistic regression analysis showed that age, gender(female), history of hypertension, history of hyperlipidemia, HbA 1C, urinary microalbumin, homeostasis model assessment for insulin resistance, and triglycerides and glucose index were independently associated with diabetes. OR were 1.053(95% CI 1.038-1.069), 0.681(95% CI 0.512-0.906), 1.802(95% CI 1.227-2.626), 1.789(95% CI 1.303-2.448), 10.973(95% CI 8.318-14.745), 1.002(95% CI 1.001-1.004), 2.914(95% CI 2.248-3.799), and 2.673(95% CI 2.03-3.536), respectively. The areas under ROC curves of the training set and the validation set were 0.945 and 0.955, respectively. The optimal critical value in the ROC curve was 0.178(sensitivity 0.930, specificity 0.839) in the training set and 0.201(sensitivity 0.945, specificity 0.848) in the validation set. Conclusion:The screening model of type 2 diabetes developed in this study has good accuracy, which can be used as a screening tool for high-risk population of type 2 diabetes.

Objective:To evaluate clinical efficacy and safety of topical compound oleum lithospermi in the treatment of mild to moderate diaper dermatitis.Methods:A multicenter, randomized, positive-drug parallel-controlled clinical trial was conducted in 19 hospitals from July 2019 to August 2020. Children aged 0 - 12 months with mild to moderate diaper dermatitis were enrolled and randomly divided into 2 groups using a random number table: test group topically treated with compound oleum lithospermi, and control group topically treated with zinc oxide cream. The treatment was carried out 6 - 8 times a day for 7 days. Visits were scheduled on days 0 and 7, and total response rate and clinical healing time were evaluated. Changes in the dermatitis family impact (DFI) score were compared between the test group and control group, and adverse events were recorded. Statistical analysis was carried out by using independent-sample t test for normally distributed continuous data, Wilcoxon rank sum test for non-normally distributed continuous data, and chi-square test or Fisher′s exact test for unordered categorical data; survival curves were drawn, and log-rank test was used for comparisons between two groups. Results:A total of 343 children with diaper dermatitis were enrolled in this study. Among them, 31 children violated the protocol, so 312 were included in the per protocol set, including 157 in the test group and 155 in the control group, and all completed the visits on days 0 and 7. The total response rate was significantly higher in the test group (87.26%, 137/157) than in the control group (78.71%, 122/155; χ2 = 4.04, P = 0.044) . The clinical healing time was significantly shorter in the test group (5.33 days) than in the control group (6.13 days; χ2 = 4.67, P = 0.025) . After 7-day treatment, the DFI score significantly decreased in both the 2 groups compared with that before the treatment, but there was no significant difference in the DFI score between the 2 groups (test group: 4.02 ± 6.96, control group: 3.58 ± 5.90, Z = -0.39, P = 0.686) . The incidence of adverse events was 2.92% (5/171) and 5.45% (9/165) in the test group and control group respectively, and there was no significant difference between the 2 groups ( χ2 = 0.03, P = 0.865) . Conclusion:Compound oleum lithospermi can markedly reduce the clinical severity of diaper dermatitis, improve the total response rate, shorten the clinical treatment period, and improve the quality of life of children′s families with a favorable safety profile.

Objective:To investigate the effects of genomic location of a foreign gene in Shanghai-191 strain measles virus (MV) vector on gene expression and virus replication.Methods:The nucleotide sequence encoding S1 protein of SARS-CoV-2 was inserted at different positions in MV antigenome (the upstream of the N gene, between P and M genes, between H and L genes), and co-transfected into 293T cells with helper plasmids coding T7 RNA polymerase and N, P, and L proteins, respectively. The transfected cells were lysed and the supernatants were used to infected Vero cells to harvest recombinant viruses. S1 proteins expressed by the recombinant viruses were identified by RT-PCR, indirect immunofluorescence assay, Western blot and ELISA. Growth kinetics of the recombinant viruses were analyzed.Results:Recombinant viruses were failed to be rescued when the S1 protein-coding sequence was cloned into the upstream of N gene. Two recombinant viruses, MV-M-S1 and MV-L-S1, were successfully rescued when cloning the S1 protein-coding sequence into the intergenic region between P and M genes, or H and L genes, and could express S1 protein. MV-M-S1 expressed more S1 protein than MV-L-S1, but the titer of MV-M-S1 was lower.Conclusions:Inserting a foreign gene at different positions in the MV genome might have different effects on gene expression and virus replication. This study provided reference for the subsequent construction of MV vector.

Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.

OBJECTIVE To monitor the occurrence of tenofovir disoproxil fumarate （TDF）-induced kidney injury and investigate the risk factors， and provide reference for rational use of TDF in clinic. METHODS The information of inpatients with hepatitis B was collected by China Hospital Pharmacovigilance System （CHPS） from the Second People’s Hospital of Lanzhou during Jan. 1st， 2019 to Dec. 31st 2021. The search criteria were set according to kidney injury criteria， and suspected TDF- induced kidney injury cases were actively monitored； then the clinical pharmacist confirmed the positive patients with TDF-induced kidney injury one by one and calculated the incidence of TDF-induced renal injury； the risk factors for TDF-induced kidney injury in real world were explored by collecting and analyzing the correlation of basic data of patients， main indexes of liver and kidney function， complications and combined use of drugs with TDF-induced renal indexes. RESULTS Totally 1 226 inpatients with hepatitis B using TDF were included. Through active monitoring of CHPS， 160 suspected patients with TDF-induced kidney injury were found， and 64 positive patients were finally confirmed manually. The incidence of TDF-induced kidney injury was 5.22%. Compared with pre-medication， the levels of serum creatinine and cystatin C， the proportion of patients with urinary protein 2+ and above were increased significantly after medication （P＜0.001）， glomerular filtration rate and blood phosphorus level were reduced significantly （P＜0.001） and other indicators had no statistical difference. Treatment time for more than 36 months， disease progresses to decompensated cirrhosis， and concomitant use of more than 10 kinds of drugs were significantly correlated with TDF- related kidney injury （P＜0.05 or P＜0.012 5）. CONCLUSIONS The active monitoring scheme of TDF-induced kidney injury established by CHPS has the characteristics of time-saving， labor-saving and high efficiency； based on real-world evidence， it is imperative to strengthen monitoring kidney function of patients when using TDF， especially when the patient has been on medication for a long time， in decompensated cirrhosis and combination of multiple drugs， and thus， we can identify earlier and avoid adverse effects in high-risk patientseffectively.
