ObjectiveTo explore the therapeutic effect of Huangliansan on atopic dermatitis （AD） model mice induced by 2， 4-dinitrochlorobenzene （DNCB）. MethodA total of 42 male BALB/c mice were randomly divided into normal group， model group， hydrocortisone group， low， medium， and high-dose groups （0.3， 0.6， 1.2 g·kg^-1） of Huangliansan oil， and water extract group （0.6 g·kg^-1） of Huangliansan. In addition to the normal group， DNCB was applied on the back of mice in other groups to establish the AD model. On the 15^th day after DNCB stimulation， each group was given the corresponding drug or solvent， and the changes in skin lesions， dermatitis score， and frequency of scratching were observed and recorded. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes in the skin and spleen. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA levels of filaggrin （FLG）， lorophane （LOR）， and involucrin （IVL） in skin， as well as immunoglobulin E （lgE）， interleukin-4 （IL-4）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and interferon-γ （IFN-γ） in spleen. ResultCompared with the normal group， the model group showed symptoms of skin swelling and scab， and the score of dermatitis， the frequency of scratching， and the spleen index were increased （P<0.05）. The expression levels of FLG， LOR， and IVL in skin tissue were significantly decreased （P<0.01）， and the mRNA expressions of IgE， IL-4， IL-6， IL-1β， and TNF-α in the spleen were significantly increased， while the expression level of IFN-γ was significantly decreased （P<0.01）. Compared with the model group， the symptoms of skin erythema， scaly， and scab of mice in each drug group were alleviated to varying degrees， and the score of dermatitis， the frequency of scratching， and the spleen index were decreased （P<0.05， P<0.01）. In addition， the expression levels of FLG， LOR， and IVL in the skin of mice in the drug group were increased （P<0.05， P<0.01）， and the mRNA expression of IgE， IL-4， IL-6， IL-1β， and TNF-α in spleen were decreased. IFN-γ was increased （P<0.05， P<0.01）， and the lesions of the skin and spleen were improved to varying degrees. The medium-dose group of Huangliansan oil and hydrocortisone group had the most obvious manifestations （P<0.05， P<0.01）. The indexes in the medium-dose group of Huangliansan oil were better than those in the water extract group of Huangliansan. ConclusionHuangliansan may improve the expression level of skin barrier protein， inhibit the expression of helper T cell 2 （Th2）-related inflammatory factors， increase the expression of helper T cell 1 （Th1） inflammatory factors， restore the skin barrier function and Th1/Th2 balance in the spleen， regulate the inflammatory response in the spleen of AD mice， and thus relieve AD. Huangliansan oil is more effective than water extract.

Objective:To investigate the prevalence of adult skeletal fluorosis caused by drinking tea-type endemic fluorosis in Yushu Tibetan Autonomous Prefecture (hereinafter referred to as Yushu Prefecture), Qinghai Province, and provide scientific basis for prevention and control of the disease.Methods:In August 2021, one village was selected as a survey site in six counties (cities) in Yushu Prefecture, including Nangqian, Chindu, Yushu, Zadoi, Qumarlêb, and Zhiduo. Drinking water samples and 10 brick tea samples were collected from each village to determine the fluoride content in water and brick tea; at least 100 permanent residents aged ≥ 25, who had a habit of drinking brick tea and had lived in the local area for more than 5 years, were selected for X-ray imaging to examine the prevalence of adult skeletal fluorosis.Results:A total of 75 samples of residential drinking water were collected, with a fluoride content of (0.21 ± 0.05) mg/L, ranging from 0.11 to 0.34 mg/L; 60 samples of brick tea, with a fluoride content of (626.70 ± 157.27) mg/kg, ranging from 324.00 to 2 102.00 mg/kg. A total of 1 136 adults were examined, and 318 cases of skeletal fluorosis were diagnosed, with a detection rate of 27.99%. Among them, the detection rates of mild, moderate, and severe skeletal fluorosis were 20.95% (238/1 136), 6.07% (69/1 136), and 0.97% (11/1 136), respectively, with mild symptoms being the main. The detection rates of skeletal fluorosis in males and females were 29.09% (121/416) and 27.36% (197/720), respectively, with no statistically significant difference between the gender (χ 2 = 0.39, P = 0.533). Comparison of the skeletal fluorosis in different gender, the differences were statistically significant (χ 2 = 22.31, P < 0.001). The detection rates of skeletal fluorosis in the age groups of 25 - 35, 36 - 45, 46 - 55, 56 - 65, 66 - 75, and ≥76 years old were 6.86% (7/102), 22.37% (51/228), 24.02% (92/383), 37.44% (73/195), 43.48% (70/161), and 37.31% (25/67), respectively. The differences between the groups were statistically significant (χ 2 = 59.84, P < 0.001). Moreover, there was a statistically significant difference in the composition of skeletal fluorosis among different age groups ( H = 37.66, P < 0.001). The Spearman correlation analysis results showed that the severity of adult skeletal fluorosis was positively correlated with age ( r = 0.34, P < 0.001). Conclusions:There is a certain degree of prevalence of adult skeletal fluorosis in Yushu Prefecture. And as age increases, the condition of skeletal fluorosis becomes more severe.

Objective To analyze the differences in the expressions of the total and phosphorylated proteins in human colon cancer HCT116 cells after the knockout(KO)of retinoic acid-induced protein 16(RAI16)and explore the possible mechanism and related signaling pathways affecting its protein function in HCT116 cells.Methods HCT116 KO and WT cell proteins were collected and extracted,and the protein extraction efficiency was detected via a sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)experiment.After protein digestion,the peptides were labeled with TMT and analyzed via mass spectrometry.We used bioinformatics methods to analyze the identified differential proteins and differentially phosphory-lated proteins by using GO,KEGG,and STRING databases.Results The results of SDS-PAGE showed no evident protein degradation.In addition,some key bands were significantly different between the experi-mental and control groups.A total of 147 up-regulated and 230 down-regulated differential proteins were screened in accordance with the conditions of Foldchange≥1.5 or Foldchange≤1/1.5 and P<0.05.Meanwhile,106 up-regulated and 217 down-regulated phosphorylation sites were screened.GO enrichment analysis revealed that the differential proteins were mainly enriched in the composition of nucleoplasm,nucleus and cytoplasm,RNA binding,cadherin and chromatin,DNA repair,RNA splicing,and positive regulation of DNA as template transcription.The results of KEGG enrichment indicated that the differential proteins were mainly enriched in nucleocytoplasmic transport,spliceosomes,cell cycle,cell-cell tight junctions,viral carcinogenesis,microRNAs in cancer,etc.The protein interaction network mainly focused on DDX17,NCL,EEF2,CDK1,SSRP1,and SMARCC1.The statistical findings unveiled the up-regulated changes in the two omics of SKP1,ORC1,and BAD and the down-regulated changes in RBL1,RB1,CDK1,CDC6,MCM4,TFDP1,CHD4,and SNW1.Moreover,the phosphorylation differences were more significant than the protein differences.Conclusion RAI16 plays the possible crucial role in multiple biological functions and signaling pathways through key proteins,such as SKP1,ORC1,RB1,and CDK1,which affect the cell cycle and thereby the occurrence and development of cancer.

Objective:To determine incidence of seasonal influenza virus infection in the community and to analyze the factors influencing seasonal influenza virus infection.Methods:This study recruited residents aged 6-59 years to build a cohort in 15 villages/streets in Macheng city in November 2019. Meanwhile, a cross-sectional baseline survey was conducted immediately to collect sera, information on demographics and child protection knowledge, behaviors, as well as attitudes using a questionnaire from the participants enrolled in the cohort (i.e., before the influenza epidemic season). In July 2020, a cross-sectional follow-up survey was conducted to collect sera once again (i.e., after the influenza season). Paired sera from the two cross-sectional surveys were tested for influenza virus-specific antibodies by hemagglutination inhibition (HI) test or micro-neutralization (MN) test using a circulating representative strain of each subtype/lineage of influenza virus as the test antigen. The infections with influenza virus subtype/lineage was confirmed if there was a four-fold or more increase in titers of antibodies against circulating representative strain of the subtype/lineage of influenza virus. Factors influencing infection with influenza A (H3N2) and B/Victoria viruses were analyzed using univariable and multivariable logistic regression.Results:In November 2019, 800 study participants were enrolled in the cohort, including 340 children aged 6-17 years and 460 adults aged 18-59 years; 605 study participants (including 224 children and 381 adults) were followed up in July 2020 and their paired sera were obtained before and after the influenza season. 25.3% (153/605) of the participants were confirmed to be infected with at least one subtype/lineage of seasonal influenza virus by HI and MN tests. The overall incidence of influenza viruses of all subtypes/lineages in children was 44.2% (95% CI: 37.6%-50.8%) which was significantly higher than the incidence of 14.1% in adults (95% CI: 10.7%-17.7%). Children had the highest incidence of influenza A (H3N2) virus infection, followed by B/Victoria. MN or HI antibody titers in A (H3N2)[ OR=0.88 (95% CI: 0.84-0.93)] and B/Victoria[ OR=0.97 (95% CI: 0.95-0.99)] before the influenza season were significantly associated with whether children were infected with that subtype/lineage of influenza virus. Conclusions:The residents aged 6-59 years in Macheng city had a substantial incidence of seasonal influenza virus infection during the influenza season from winter 2019 to spring 2020. Notably, almost half of children aged 6-17 years have been infected with seasonal influenza virus. Higher titers of HI/MN antibodies against seasonal influenza virus before the influenza season would be likely to reduce the risk of infection with influenza A (H3N2) and B/Victoria.

Objective:To construct a prediction model for the emergency volume of the psychiatric hospital, and analyze the changes of psychiatric emergency visits, so as to provide references for optimizing the allocation of emergency service resources.Methods:This study extracted data of the visit time of emergency patients, etc from the information system of a certain psychiatric hospital from 2018 to 2023. The monthly emergency visits (emergency volume) from 2018 to 2022 were used to construct the autoregressive integrated moving average model (ARIMA), and the monthly emergency volume from 2023 was used to validate the predictive performance of the model.Results:After model construction and screening, seasonal ARIMA (0, 1, 0) (1, 1, 1) 12 was determined as the optimal model. The predicted values of the model were in good agreement with the actual values, with an average relative error fluctuation of 1.6% to 26.8% and an average absolute error fluctuation of 9 to 159 person-time. Conclusions:The seasonal ARIMA model could accurately predict the emergency volume of a certain psychiatric hospital and provide references for human resource allocation and emergency response. However, this prediction model was suitable for short-term forecasting. If long-term forecasting was needed, continuous data fitting was necessary to ensure the effectiveness of the prediction.

Objective:To construct a prediction model for peripherally inserted central catheter-related upper extremity deep vein thrombosis (PICC-UEDVT) in patients with traumatic brain injury (TBI) and validate its effectiveness.Methods:A case-control study was conducted on the clinical data of 222 TBI patients admitted to Xiangya Hospital of Central South University from January 2019 to December 2021, including 171 males and 51 females, aged 18-86 years [54.5(46.0, 65.0)years]. Glasgow coma scale (GCS) motor score was 4.0(3.0, 5.0)points on the day of catheterization. A total of 82 patients (36.9%) had PICC-UEDVT. The patients were randomly divided with a ratio of 7∶3 into training set ( n=156, including 58 with PICC-UEDVT) and validation set ( n=66, including 24 with PICC-UEDVT) using R programming language. The baseline data of general information, intravenous medication, catheterization, and laboratory indices were compared between the training set and the validation set. Lasso regression analysis was employed to identify those variables, with the diagnosis of PICC-UEDVT as the outcome variable. Variables with non-zero regression coefficients were included in a multifactorial Logistic regression model and independent variables were selected based on the Akaike Information Criterion (AIC) of R programming language. The regression equation was constructed, based on which, the predictive nomogram model was constructed for PICC-UEDVT in TBI patients. Receiver operating characteristic (ROC) curves for the training set and validation set were plotted and the discriminability of the model was assessed. The calibration of the model was evaluated using the Hosmer-Lemeshow (H-L) goodness-of-fit test and calibration curves and the clinical practicality of the model was assessed with decision curve analysis (DCA). Results:The baseline analysis of both the training set and the validation set demonstrated a well-balanced sample distribution. Through Lasso regression analysis, 5 prediction variables were identified: GCS motor score on the day of catheterization, Caprini score on the day of catheterization, use of glucocorticoids, tip position of the catheter, and D-dimer (D-D) level before catheterization. The multivariate Logistic regression analysis revealed that the Caprini score on the day of catheterization ( OR=1.20, 95% CI 1.08, 1.33), use of glucocorticoids ( OR=3.13, 95% CI 0.99, 10.46), and D-D level before catheterization ( OR=1.16, 95% CI 1.07, 1.33) were independent risk factors for PICC-UEDVT in TBI patients. The regression equation was developed as: Logit [ P/(1- P)]=-2.56+0.18×"Caprini score on the day of catheterization"+1.14×"use of glucocorticoids"+0.15×"D-D level before catheterization". In the prediction model which was constructed based on the equation, the AUC values for the training set and validation set were 0.73 (95% CI 0.65, 0.81) and 0.77 (95% CI 0.65, 0.87) respectively. The H-L goodness-of-fit test indicated χ2=3.28, P=0.950 for the training set and χ2=13.05, P=0.160 for the validation set. Calibration curves for both sets demonstrated alignment between the actual and predicted probabilities of PICC-UEDVT in TBI patients. DCA results showed that the net benefit rate of patients was optimal when the threshold probability ranged from 15% to 72% for the training set and from 10% to 81% for the validation set. Conclusion:The prediction model based on the Caprini score on the day of catheterization, use of glucocorticoids, and D-D level before catheterization demonstrates good predictive accuracy, calibration and clinical practicality in predicting PICC-UEDVT in TBI patients.

Objective:To learn about the detection quality and external quality control assessment of fluoride and arsenic in laboratories at all levels in Qinghai Province.Methods:The Z-score method was used to analyze and evaluate the evaluation results of 1 provincial, 8 municipal and 43 county level laboratories of disease prevention and control institutions participating in the external quality control assessment of water fluoride and brick tea fluoride in Qinghai Province in 2021, as well as 1 provincial, 1 municipal and 2 county level laboratories of disease prevention and control institutions participating in the external quality control assessment of water arsenic and urine arsenic. The feedback rate and qualification rate of external quality control of each assessment laboratory were calculated.Results:In 2021, the feedback rate of external quality control of water fluoride, brick tea fluoride, water arsenic and urine arsenic in provincial and municipal level laboratories of Qinghai Province were 100.00%; except that the qualified rate of water fluoride was 7/9, the qualified rate of external quality control of other projects was 100.00%. The feedback rate of external quality control of water fluoride, brick tea fluoride, water arsenic and urine arsenic in county level laboratories was 100.00%; except that the qualified rate of water fluoride was 86.05% (37/43), the qualified rate of external quality control of other projects was 100.00%. In the specific assessment results of the laboratory, the assessment results of water fluoride sample FS20210101 from 1 provincial, 1 municipal and 2 county level laboratories, and FS20210102 from 1 county level laboratory were suspicious; the assessment results of water fluoride sample FS20210101 from 3 county level laboratories were not satisfactory; the assessment results of fluoride and arsenic sample in other laboratories were satisfactory.Conclusions:The qualified rate of external quality control of fluoride and arsenic in laboratories at all levels in Qinghai Province is relatively high, but some county level laboratories are still dissatisfied with the assessment results of water fluoride. Therefore, it is necessary to strengthen the detection level of water fluoride in laboratories.

Objective:To observe the changes of serum C-terminal peptide of type Ⅰ collagen (CTX-1) and N-terminal lengthening peptide of type Ⅰ collagen (P1NP) in adult patients with skeletal fluorosis in the tea-drinking-borne endemic fluorosis area in Qinghai Province, and to find sensitive indicators for diagnosis of skeletal fluorosis.Methods:From April to August 2019, a case-control study was carried out in tea-drinking-borne endemic fluorosis area in Zhiduo County, Yushu Tibetan Autonomous Prefecture, and Gangcha County, Haibei Tibetan Autonomous Prefecture of Qinghai Province. According to the Diagnostic Standard for Endemic Skeletal Fluorosis (WS/T 192-2008), the clinical diagnosis and X-ray examination of skeletal fluorosis were carried out for permanent residents ≥25 years old and living for more than 10 years in the area, combined with face-to-face inquiry and investigation of past disease history, lifestyle and clinical manifestations. The patients with skeletal fluorosis and healthy people were selected as skeletal fluorosis group and control group, respectively. Randomized urine samples and fasting venous blood from the two groups were collected. The content of fluoride in urine was determined by ion selective electrode method, and the contents of CTX-1 and P1NP in serum were determined by enzyme-linked immunosorbent assay (ELISA).Results:A total of 127 people in the disease area were investigated, including 63 cases in skeletal fluorosis group and 64 cases in control group. There was no statistically significant difference in age and sex ratio between the two groups ( t = 0.42, χ 2 = 0.07, P > 0.05). The X-ray examination results showed that the patients with skeletal fluorosis were mainly mild, accounting for 71.43% (45/63); X-ray changes were mainly ossification of interosseous membrane and tendon. The urinary fluoride in control group and skeletal fluorosis group was 1.62 (1.12, 1.95) and 3.22 (2.38, 4.89) mg/L, respectively, with statistically significant difference between the two groups ( Z = 7.07, P < 0.001). The difference of serum CTX-1 and P1NP contents between the two groups was statistically significant ( Z = 2.00, 4.89, P < 0.05). Conclusions:The levels of serum CTX-1 and P1NP in patients with skeletal fluorosis are higher than those in healthy people. Serum CTX-1 and P1NP may be used as sensitive indicators for diagnosis of skeletal fluorosis.

Objective:To explore the optimal evidence for the nursing management of limb spasm in patients with spinal cord injury.Methods:Based on the "6S" evidence model, the databases including CNKI, Wanfang, PubMed and Cochrane Library, the guideline websites such as the National Guideline Clearinghouse, Guidelines International Network and Registered Nurses′ Association of Ontario, and the websites of professional associations such as the Royal College of Physicians, American Spinal Injury Association and Canadian Spine Association were systematically searched. Search period of each database was set from the year of inception until July 2022. Two investigators independently screened the literatures related to the management of limb spasm in patients with spinal cord injury, and conducted quality evaluation and evidence recommendation level evaluation.Results:Totally 17 literatures consisting of 6 guidelines, 3 expert consensuses, 5 systematic reviews, 2 evidence summaries, and 1 clinical decision were included. Moreover, 30 pieces of evidence were summarized from 3 aspects, including evaluation and identification, drug therapy (chemical denervation, and oral medication), rehabilitation training (hydrotherapy, electrical stimulation, magnetic stimulation, vibration therapy, heat and cold therapy, body position, and exercise therapy).Conclusion:Nursing staff can set up a multidisciplinary team according to the clinical environment and take into consideration of the characteristics of spinal cord injury patients to provide personalized interventions involving evaluation and identification, drug therapy, rehabilitation training, etc., so as to alleviate the degree of limb spasm.
