ObjectiveTo explore the effectiveness of feedforward control mode on improving occupational burnout among operating room nurses through theoretical research and clinical practice， with a view to promoting their physical and mental health and enhancing the quality of surgical nursing. MethodsA total of 440 operating room nurses from different regions， scales， and nursing experiences in Shaanxi Province from November 2023 to December 2023 were randomly divided into an experimental group and a control group， with 220 nurses in each group. While the control group received routine intervention measures， the experimental group introduced a feedforward control mode based on the control group， with “emotional exhaustion，” “depersonalization，”and“personal achievement” as observation indicators. ResultsThe incidence of occupational burnout in the experimental group was 11.4%， while that in the control group was 20.0%. The experimental group showed a significantly lower incidence than the control group （P=0.013）. ConclusionThe feedforward control mode can significantly alleviate nurses’ sense of job burnout， promote the improvement of surgical nursing quality， as well as continuously improve the scientific rigor， advancement， and humanistic nature of nursing services， which is conducive to building a harmonious and efficient nursing team. The spirit of teamwork， reflected in mutual support， mutual trust， and joint efforts for surgical success and patient health， has become an important component of nurses’ professional ethics.

BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

OBJECTIVE: To assess the impact of long-term biologic therapy on metabolic biochemical parameters in moderate to severe plaque psoriasis patients. METHODS: The study included patients over 18 years old who had been treated by biological agents for at least 24 weeks for moderate to severe plaque psoriasis from Novermber 2015 to January 2024. According to the biological agents the patients used, they were divided into three groups: interleukin-17 (IL-17) inhibitor group, IL-23 and IL-12/23 inhibitor group and tumor necrosis factor-α (TNF-α) inhibitor group. The metabolic biochemical parameters of each group were evaluated and compared before and after the administration of the biologic therapies. RESULTS: A total of 174 patients with moderate to severe plaque psoriasis were included in the long-term treatment with biologics, including 127 males (73.00%), 47 females (27.00%), with a median age of 38.00 (31.50, 49.00) years and a median duration of psoriasis of 12.00 (10.00, 20.00) years. The median duration of biologic treatment was 61.00 (49.00, 96.25) weeks, ranging from 26 to 301 weeks. There were 101 patients in the IL-17 inhibitor group, 38 patients in the IL-23 and IL-12/23 inhibitor group, and 35 patients in the TNF-α inhibitor group. After long-term treatment with IL-17 inhibitors, no statistically significant changes were observed in body weight, body mass index (BMI), alanine aminotransferase (ALT), aspartate aminotransferase (AST), fasting glucose (GLU), total cholesterol (TC), triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C) compared with baseline measurements (P>0.05). However, low-density lipoprotein cholesterol (LDL-C) levels were significantly reduced [(2.90±0.75) mmol/L vs. (3.05±0.79) mmol/L, t=－2.100, P=0.038], while uric acid (UA) levels showed a significant increase [(401.13±99.13) μmol/L vs. (364.94±91.11) μmol/L, t=5.215, P < 0.001]. The group with normal UA levels before treatment showed a significant increase after long-term application of biological agents compared with before treatment [(370.69± 89.59) μmol/L vs. (324.66±64.50) μmol/L, t=5.856, P < 0.001]. Following long-term application of IL-23 and IL-12/23 inhibitors, no statistically significant differences were observed in body weight, BMI, ALT, AST, GLU, TC, TG, HDL-C and UA levels when compared with baseline measurements (P> 0.05). However, LDL-C levels exhibited a significant reduction from baseline [(2.85±0.74) mmol/L vs. (3.12±0.68) mmol/L, t=－2.082, P=0.045]. After long-term treatment with TNF-α inhibitor, there were no significant differences in body weight, BMI, ALT, AST, GLU, TC, TG, HDL-C, LDL-C and UA compared with baseline measurements (P>0.05). CONCLUSION Long-term application of IL-17 inhibitors in moderate to severe plaque psoriasis patients may result in elevated uric acid levels, particularly in patients with normal uric acid levels before treatment. The long-term use of IL-17 inhibitors, IL-23 inhibitors or IL-12/23 inhibitors might reduce LDL-C levels.

Objective:To analyze the epidemiological characteristics and economic burden of palmoplantar pustulosis (PPP) in China.Methods:A population-based retrospective study was conducted using the data from China′s Urban Basic Medical Insurance data from January 1, 2012, to December 31, 2016. International Classification of Diseases code and diagnoses in Chinese for PPP were used to identify cases and estimate the prevalence, incidence, and cost. Subgroup analyses were performed according to age and sex, and sensitivity analyses were conducted to evaluate the robustness of the results. Age-adjusted prevalence rates were calculated based on the 2010 national census data.Results:The crude prevalence and incidence rate of PPP in 2016 were 2.730/100 000 (95% CI: 2.218/100 000-3.242/100 000) and 1.556/100 000 (95% CI: 1.154/100 000-1.958/100 000), and the prevalence rate of females (2.910/100 000) was higher than that of males (2.490/100 000, χ2=97.48, P=0.001). The incidence rate of females (1.745/100 000) was also higher than that of males (1.418/100 000, χ2=85.02, P=0.001). The age peak of incidence and prevalence of patients with PPP was in the 30-39-year age group and a small peak existed in the 0-3-year age group among people under 20 years old. From 2012 to 2016, the average number of visits was (2.44±0.04) per patient, and the total per-capita cost per year was (982.40±39.19) yuan. Conclusion:In 2016, the prevalence and incidence rate of PPP in China were higher in females than in males, and the highest age peak was in the 30-39-year age group.

ObjectiveBioinformatics methods were used to systematically identify the Salvia miltiorrhiza terpenoid synthase （SmTPS） gene family members and predict their functions from the perspective of the genome. MethodThe genome and transcriptome data of S. miltiorrhiza， Arabidopsis thaliana， and tomato were obtained from the national genomics data center （NGDC）， national center for biotechnology information （NCBI）， the Arabidopsis information resource （TAIR）， and tomato functional genomics database （TFGD）， and the whole genome identification and bioinformatics analysis of the SmTPS gene family member were carried out with the help of Perl language programming， Tbtools， and other bioinformatics tools. ResultA total of 52 TPS gene family members were identified， and they were distributed on eight chromosomes of S. miltiorrhiza. Their coding amino acid number was 207-822 aa. The isoelectric points were 4.76-9.16. The molecular mass was 24.11-94.81 kDa， and all members are hydrophilic proteins. Gene structure analysis showed that there were significant differences in the number of introns among different subfamilies. The number of introns in 72.6% of TPS-a， b， and g subfamilies was 6， and that in 88.9% of TPS-c and e/f subfamilies was more than 10. Protein motifs were conserved among TPS subfamilies. The analysis of promoter cis-acting elements showed that all promoters of the SmTPSs contained a large number of light-responsive elements， and most of them had hormone-responsive elements. Gene expression analysis showed that SmTPS gene family members exhibited tissue-specific expression， and 24 of them responded to exogenous methyl jasmonate. ConclusionBased on the published S. miltiorrhiza genome， 52 SmTPS gene family members were identified， and their functions were predicted based on the phylogenetic analysis and expression patterns. This paper provides reference information for the further biosynthesis pathway and regulatory mechanism analysis of terpenoids in S. miltiorrhiza.

Objective To investigate the design of cuffed pediatric tracheal tubes and compare the effects of different tracheal intubation depth placement strategies on the position of the tracheal tube tip and cuff of 5 tracheal tube brands.Methods A total of 180 children who were admitted to Tianjin Children's Hospital from October 2020 to December 2021,with endotracheal intubation under general anesthesia,aged 1-6 years,were enrolled.The length of the subglottic airway was measured by electronic bronchoscopy.Dimensional data from 5 cuffed pediatric tracheal tube brands were recorded,including the length of the tracheal tube cuff,the distance from the tip of the tracheal tube to the upper edge of the cuff,and the tip of the tracheal tube to the lower edge of the tube glottis marker line the distance.Calculation of the required cuffed endotracheal tube internal diameter(ID)for 180 pediatric patients was performed based on the Motoyama formula,the positions of tracheal tube tip and upper cuff border were calculated for each of the 180 tracheas using depth mark to based tracheal tube placement,placement of the tracheal tube tip at 2 cm above the carina,and mid-tracheal tube placement.Results There were differences in the dimensional data of the 5 cuffed pediatric tracheal tube brands.Depth mark-based tracheal tube placement resulted in the incidence rate of tube tip to carina placement less than 1 cm was 3.9%-67.8%,and the highest incidence of bronchial intubation is Ruijing,up to 17.8%.The tracheal tube tip was placed 2 cm above the carina,and no improper placement of the tracheal tube cuff and tube tip was found in all brands.Mid-tracheal tube placement led to 100%subglottic and supraglottic tracheal tube cuff positions,except Weili.Conclusions There are differences in design between different brands of cuffed pediatric tracheal tube,and some of the design deficiencies may lead to the risk of airway complications.The method used to guide the insertion depth and the brand of cuffed tracheal tubes can affect the tracheal tube position.Placement of the tracheal tube tip at 2 cm above the carina allowed safe tracheal tube placement in children aged 1-6 years.

Objective To analyze the serum levels of apurinic/apyrimidinic endonuclease 1 autoantibodies (APE1-AAbs) and growth differentiation factor 15 (GDF-15) and their predictive value for postoperative recurrence and metastasis in patients with colorectal cancer. Methods Fifty-two patients with colorectal cancer were selected as observation group, and were divided into postoperative recurrence and metastasis group (n=15) and non-recurrence and metastasis group (n=37) according to prognosis. Fifty-two healthy individuals undergoing routine physical examination during the same period were selected as the control group. The levels of APE1-AAbs and GDF-15 were measured. Pearson correlation analysis was used to analyze the correlations of APE1-AAbs, GDF-15 with post-surgical recurrence and metastasis of colorectal cancer. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of APE1-AAbs and GDF-15 for post-surgical recurrence and metastasis of colorectal cancer. Results The levels of APE1-AAbs and GDF-15 in the observation group were significantly higher than those in the control group (P < 0.05). The levels of APE1-AAbs and GDF-15 in the postoperative recurrence and metastasis group were significantly higher than those in the non-recurrence and metastasis group (P < 0.05). There was a positive correlation between the levels of APE1-AAbs, GDF-15 and post-surgical recurrence and metastasis of colorectal cancer (P < 0.05). The combined use of APE1-AAbs and GDF-15 had higher predictive value for post-surgical recurrence and metastasis of colorectal cancer than either single prediction (P < 0.05). Conclusion APE1-AAbs and GDF-15 are highly expressed in the serum of colorectal cancer patients. APE1-AAbs and GDF-15 may serve as markers for post-surgical recurrence and metastasis of colorectal cancer.
