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 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 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 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 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 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.

Respiratory diseases are common， frequently-occurring clinical diseases. As the prevalence rate is increasing year by year， they have become a problem that seriously affects public health. The diseases are mainly located in the lung by traditional Chinese medicine （TCM） syndrome differentiation. Lung governs Qi and controls breathing and is also an organ for the storage of phlegm. Clinically， phlegm and Qi are often used for the treatment. Banxia Houputang （BHT）， originated from Synopsis of the Golden Chamber （《金匮要略》）， was used to treat plum-stone Ai （globus hystericus） at first. It is composed of Rhizoma Pinelliae， Cortex Magnoliae Offcinalis， Poria， Rhizoma Zingiberis Recens， and Folium Perillae， and treats diseases with the core pathogensis of mutual obstruction of phlegm and Qi. BHT has the effects of moving Qi， dissipating mass， descending adverse Qi， and resolving phlegm， which basically correspond to the pathological characteristics of the lungs. Clinical studies have confirmed that modified BHT can be used either alone or in combination with western medicine to treat chronic pharyngitis， asthma， chronic obstructive pulmonary disease， pneumonia， obstructive sleep apnea， upper airway cough syndrome and other respiratory diseases， with significant effects. It effectively improves the symptoms and signs of the diseases and reduces the recurrence rate. Basic research has shown that BHT plays anti-inflammatory， anti-oxidative stress， anti-apoptotic， autophagy-regulating， and iron overload-regulating roles by regulating the targets in multiple pathways. This paper， by combing the relevant literature in recent years， conducted a systematic review on BHT from the three aspects of syndrome analysis， clinical treatment research and mechanism research， with a view to providing theoretical basis and reference for the mechanism research of BHT in treating respiratory diseases and for expanding its clinical application.

SARS-CoV-2 Omicron variant (B.1.1.529) was first discovered in South Africa in November 2021 and has since become a mainstream strain worldwide. Omicron variant was defined as the fifth "variant of concern (VOC)" by World Health Organization on November 26, 2021. This paper illustrates the mutation trends of Omicron variants in terms of SARS-CoV-2 genome and protein structure as well as nucleic acid site mutations and amino acid site mutations, describes the features of Omicron mutation sites in terms of lineage comparison among the VOCs and Omicron sublineages, and further highlights the influences of Omicron site mutations from the aspects of immune escape, virulence and transmission ability. Moreover, this paper also reviews the development of direct antiviral agents, antibodies and vaccines, aiming to provide reference for further investigation.

Objective:To investigate the effect of T helper 1 (Th1) to T helper 2 (Th2) ratio (Th1/Th2) on the prognosis of patients with multiple myeloma (MM).Methods:The clinical data of 168 MM patients who were newly diagnosed in the Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2016 to January 2021 were retrospectively analyzed. Disease staging was defined according to the Chinese guidelines for diagnosis and treatment of MM (2020 edition). Risk stratification was based on the Mayo stratification of myeloma and risk-adapted therapy (mSMART) 3.0. The levels of Th1 and Th2 in peripheral blood of patients were detected by flow cytometry. Th1/Th2 was compared among patients with different disease staging and risk stratification. Using mSMART 3.0 risk stratification as the gold standard, the receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value of Th1/Th2 for determining high-risk MM. According to the optimal cut-off value, patients were divided into high Th1/Th2 group (≥ optimal cut-off value) and low Th1/Th2 group (< optimal cut-off value). The progression-free survival (PFS) of the two groups was analyzed by Kaplan-Meier method. Multivariate Cox proportional hazards model was used to analyze the influencing factors of PFS.Results:There were 40, 62 and 66 patients with international staging system (ISS) stages Ⅰ, Ⅱ and Ⅲ, respectively, with Th1/Th2 [ M ( IQR)] of 19.20 (18.98), 15.93 (14.40) and 14.47 (12.01), respectively ( H = 6.68, P = 0.036). There were 31,102 and 35 patients with revised international staging system (R-ISS) stages Ⅰ, Ⅱ and Ⅲ, respectively, with Th1/Th2 of 19.67 (21.92), 14.87 (11.36) and 13.50 (12.80), respectively ( H = 7.26, P = 0.027). There were 99 and 69 patients with mSMART 3.0 high-risk and standard-risk, respectively, and the Th1/Th2 of high-risk patients was lower than that of the standard-risk patients [14.70 (11.93) vs. 17.72 (16.80), U = 2 612.00, P = 0.009]. ROC curve analysis showed that the area under the curve for Th1/Th2 to determine high-risk MM was 0.618 (95% CI 0.531-0.705, P = 0.010), and the optimal cut-off value was 16.55 and there were 81 and 87 cases in the high Th1/Th2 group and low Th1/Th2 group. With a median follow-up of 28 months (1-70 months), the median PFS time for all patients was 36 months (95% CI 29-43 months); PFS in high Th1/Th2 group was better than that in low Th1/Th2 group [median PFS time: 39 months (95% CI 26-51 months) vs. 28 months (95% CI 21-34 months), P = 0.040]. Multivariate Cox regression analysis showed that renal impairment (with vs. without: HR = 2.340, 95% CI 1.350-4.053, P = 0.002) and low Th1/Th2 (high vs. low: HR = 0.551, 95% CI 0.344-0.882, P = 0.013) were independent risk factors for PFS in MM patients. Conclusions:The imbalance between Th1 and Th2 is associated with the prognosis of MM patients, and patients with low Th1/Th2 are at high risk of progression. Th1/Th2 can be used as a prognostic indicator for MM.
