Aromatic traditional Chinese medicine(TCM) has played an important role against epidemics and viruses, and volatile components are the main components that exert the pharmacological effects of aromatic TCM. By screening the related monomer components in aromatic TCM against epidemic and viruses and analyzing and endowing TCM with medicinal properties based on its clinical application and pharmacological research according to the theoretical thinking of TCM, the key technical issues of compatibility of TCM monomer components were solved from a theoretical perspective, providing new ideas and methods for screening raw materials and formulas for the development of new TCM drugs. Based on the conditions of antiviral activity, clinical application foundation, definite therapeutic effect, and high safety, a gradient screening of aromatic TCM was carried out. Firstly, 30 aromatic TCM were screened from anti-epidemic literature and clinical trial formulas, and seven volatile monomers were further screened from them. Then, four monomer components with significant effects, namely patchouli alcohol, carvacrol, p-cymene, and eucalyptol were screened. By adopting the "four-step method for a systematic study of TCM properties", the four monomer components were endowed with medicinal properties, and compatibility and combination studies were conducted to explore the theoretical basis of monomer formulas and form monomer formulas guided by TCM theory. The screening results of volatile monomers in aromatic TCM against viral pneumonia included patchouli alcohol, carvacrol, p-cymene, and eucalyptol. The medicinal properties and compatibility theory of volatile monomer components in TCM were explored. Patchouli alcohol was the main herb, with a cool and pungent nature. It entered the lung meridian to dispel evil Qi and has the effects of aromatization, detoxification, and epidemic prevention. Carvacrol was a minister drug with a cool and pungent taste. It had the effects of aromatizing, moistening, and dissolving the exterior, as well as strengthening the spleen and stomach. p-Cymene was an adjunctive medicine with a mild and pungent nature. It entered the lungs and kidneys and had the effects of aromatic purification, cough relief, and asthma relief. Eucalyptol was also an adjunctive medicine with a pungent and warm taste. It had the functions of aromatic purification, cough relief, phlegm reduction, and pain relief. The combination of the four medicines had the effects of aromatizing, moistening, detoxifying, and epidemic prevention, as well as relieving cough and asthma and strengthening the spleen and stomach. They were used to treat viral pneumonia caused by upper respiratory tract viral infections, with symptoms such as chest tightness, cough, wheezing, fatigue, nasal congestion, runny nose, nausea, and vomiting. This study has laid a literature and theoretical foundation for further drug efficacy verification experiments, compatibility efficacy experiments, and subsequent product development and clinical applications, and it serves as an innovative practice that combines literature research, theoretical research, experimental research, and clinical practice to develop new products.

Objective: To investigate the association between screen time (ST) during leisure time and anxiety-depression symptoms among middle school students, so as to provide a basis for formulating relevant intervention measures. Methods: From November to December 2023, a stratified cluster random sampling method was used to select 2 542 students from junior and senior high school in Taiyuan City. A self designed questionnaire, the Generalized Anxiety Disorder Scale (GAD-7), and the Patient Health Questionnaire (PHQ-9) were used to investigate ST and anxiety/depression symptoms among middle school students. The Logistic regression model was used to explore the association of ST with symptoms of anxiety and depression, as well as with anxiety and depression comorbiditles (CAD). Results: The detection rates of anxiety symptoms, depression symptoms, and CAD were 13.69%, 15.77%, and 10.11%, respectively. The median ST was 2.00 h/d [interquartile range ( IQR =2.38) for weekly averages], with 0.33 h/d ( IQR =1.67) on work days and 5.00 h/d ( IQR=5.50) on rest days. Logistic regression analysis indicated that the total ST of mobile phones during rest days ( OR =1.07, 1.10, 1.11) and the averages ST of mobile phones over a week ( OR = 1.20 , 1.22, 1.29), as well as the total ST of all screen types during rest days ( OR =1.04, 1.04, 1.05) and the averages ST of all screen types over a week ( OR =1.08, 1.09, 1.21) were positively correlated with anxiety symptoms, depression symptoms, and CAD (all P <0.01). Conclusions Among middle school students in Taiyuan City, screen time is positively correlated with symptoms of anxiety or depression and the comorbidity of anxiety and depression, especially smartphone screen time and weekend screen use. Therefore, measures should be implemented to reduce unnecessary screen time among middle school students, especially the use of mobile phones, in order to mitigate the occurrence of anxiety and depression.

Objective To investigate the levels of serum adrenomedullin precursor(pro-ADM),soluble leukocyte differentiation antigen 14 subtype(presepsin),and eosinophil chemotactic factor-1(Eotaxin-1)in patients with acute stroke(AS)complicated with pulmonary infection and their relationship with prognosis.Methods A total of 146 patients with AS admitted to the hospital from January 2022 to January 2024 were selected as the research subjects.According to whether the research subjects were complicated with pulmonary infection,they were divided into the infection group with 54 cases and the non-infection group with 92 cases.In addition,100 healthy individuals who underwent physical examinations in the hospital during the same period were selected as the control group.The prognosis of patients was evaluated using the modified Rankin scale score,which was divided into good prognosis and poor prognosis.The levels of serum pro-ADM,presepsin,Eotaxin-1 and C-reactive protein(CRP)were detected by enzyme-linked immunosorbent assay.Multivariate Logistic regression was used to analyze the influencing factors of AS complicated with pulmonary infection,and the receiver operating characteristic(ROC)curve was plotted to analyze the diagnostic value of serum CRP,pro-ADM,presepsin,and Eotaxin-1 levels for patients with AS complicated with pulmonary infection.Compare the levels of serum pro-ADM,presepsin and Eotaxin-1 in patients with different prognoses.The rela-tionship between the levels of serum pro-ADM,presepsin and Eotaxin-1 and the prognosis of patients was ana-lyzed by the Kaplan-Meier method.Results The levels of smoking history and serum CRP,pro-ADM,presep-sin,and Eotaxin-1 in the infection group were higher than those in the non-infection group and the control group,and the difference was statistically significant(P<0.05).The results of multivariate Logistic regres-sion analysis showed that the levels of serum CRP,pro-ADM,presepsin and Eotaxin-1 were the influencing factors of AS complicated with pulmonary infection(P<0.05).The results of the ROC curve analysis show that the area under the curve(AUC)of the combined diagnosis of AS complicated with pulmonary infection by serum pro-ADM,presepsin and Eotaxin-1 levels was higher than AUC of the individual diagnosis of CRP,pro-ADM,presepsin and Eotaxin-1(Z=3.921,2.445,2.825,3.076,P<0.05).The levels of serum pro-ADM,presepsin and Eotaxin-1 in patients with poor prognosis were higher than those in patients with good progno-sis,and the difference was statistically significant(P<0.05).The results of survival analysis by the Kaplan-Meier method showed that the survival rate of patients with high expression of serum pro-ADM,presepsin,and Eotaxin-1 was lower than that of patients with low expression(P<0.05).Conclusion The levels of ser-um pro-ADM,presepsin and Eotaxin-1 in patients with AS complicated with pulmonary infection are related to their prognosis.

SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries, however, the underlying mechanism, in particular immune responses in different organs, remains elusive. In this study, comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed. Compared to normal controls, SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs, with drastic transcriptomic changes in cerebral cortex and right ventricle. Intriguingly, cerebral cortex exhibited a hyperinflammatory state evidenced by significant upregulation of inflammation response-related genes. Meanwhile, expressions of coagulation, angiogenesis and fibrosis factors were also up-regulated in cerebral cortex. Based on our findings, neuropilin 1 (NRP1), a receptor of SARS-CoV-2, was significantly elevated in cerebral cortex post infection, accompanied by active immune response releasing inflammatory factors and signal transmission among tissues, which enhanced infection of the central nervous system (CNS) in a positive feedback way, leading to viral encephalitis. Overall, our study depicts a multi-tissue/organ transcriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2, and provides important insights into the mechanistic basis for COVID-19-associated clinical complications.

Objective: To explore the intervention effect of sports combined with group psychological counseling on the psychological craving, addiction sererity, as well as comorbid depression with anxiety severity of college students with smartphone addiction. Methods: Totally 148 smart-phone addicts were randomly divided into 3 groups(sports group 49 students, group psychological counseling group 50 students, sports group counseling group 49 students). Smartphone addiction was evaluated by using the University Student Smartphone Addiction Scale(SAS-C); the degree of mental hunger was assessed by the Visual Analog Scale(VAS); the Hamilton Depression Scale(HAMD) and the Hamilton Anxiety Scale(HAMA) were used to evaluate the degree of anxiety and depression. All scales were evaluated before intervention, after intervention and 3 months after the intervention. Results: The SAS-C,VAS,HAMD,HAMA scores of the three groups decreased with time(F=36.05，38.54，37.27，39.27，P<0.01), and the scores were the lowest in the sports group counseling group, SAS-C,VAS,HAMD,HAMA followed by the group counseling group and the highest in the sports group(F=34.33，32.36，32.34，34.96，P<0.01). Howevey, all the 3 groups still had depression and anxiety symptoms after 3 months of intervention. Conclusion Sports, group psychological counseling, sports combined with group counseling can all differentially help decreasing the psychological cravings and addiction levels of smartphone addicts and severity of depression and anxiety with the latter shows the highest effectiveness, followed by the group counseling and sports intervention alone.

【Objective】 To analyze the HIV-, HCV- and HBV- NAT yield rate in different areas of Henan province, so as to provide the basis for disease prevention and control as well as the establishment of a unified quality control standard for nucleic acid testing(NAT) in the Henan province. 【Methods】 The number and prevalence of NAT yielding samples with isolated infectious virus, namely HIV, HCV and HBV, in 18 blood stations in Henan province from 2017~2019, as well as the trends were analyzed. The NAT quality of each laboratory and each testing system was analyzed according to the ratio of reactive individual donation(ID) results to reactive minipools(MP). 【Results】 The HBV, HCV and HIV ID-NAT yield numbers in 3 501 251 blood donations were HBV 2 606(74/100 000), HCV 21 (0.63/100 000), and HIV 34(1.00/100 000). The HBV ID-NAT yield rate showed an upward trend in the whole province from 2017 to 2019, while the prevalence of HIV and HCV ID-NAT yield didn′t differ significantly during three years. 5 kinds of NAT detection systems were applied in 18 blood centers. among which Ⅰ, Ⅱ, Ⅳ and Ⅴ were triplex detection systems. 2661 ID-reactive samples were implicated in 5 595 MP-reactive samples, with a resolution rate of 47.56%. The resolution rate of triplex NAT system Ⅰ, Ⅱ, Ⅳ and Ⅳ was 39.63%~47.95%, 40.43%~54.36%, 51.61% and 70.00%~45.45%, respectively. An upward trend in triplex NAT resolution rate was observed in 8 laboratories, i. e.B, D, E, F, I, K, L and Q, and an descending trend in A and C. The NAT system Ⅲ, a ID-NAT system, was used only by laboratory C, presenting a NAT-yield rate of 0.19% (282/145 474) and resolution rate of 46.45% (131/282). 【Conclusion】 The majority of NAT-yield of one infectious virus in Henan province is HBV, presenting annual increasing trend. The quality management of NAT laboratories should be strengthened as the divergence was seen in the performance of different NAT laboratories.

【Objective】 To analyze the cause of single-ELISA reactive of four blood screening items in 18 blood stations in Henan, so as to provide the basis for improving the quality of blood screening. 【Methods】 The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP of 18 blood station laboratories in Henan throughout 2019 was calculated, and the causes were analyzed according to different ELISA reagent combinations and gray area settings in each laboratory. 【Results】 The overall single-ELISA reactive rates of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP were 1.740(2 154/1 237 789), 0.564‰(698/1 237 789), 1.421‰(1 759/1 237 789) and 1.561‰(1 932/1 237 789), respectively, showing significant differences by detection items (P <0.05). Person correlation analysis showed that the single-ELISA reactive rate was independent of the gray area settings.but dependent on laboratories and reagent combinations. The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP in D laboratory was the highest and higher than that in other labs using the same reagent.The laboratories with high HBsAg single-ELISA reactive rate were mostly those using a combination of imported reagents and domestic reagents, including the top 6 laboratories. The laboratories with high anti-HCV single-ELISA reactive rate were mostly those using certain domestic reagents. No obvious rules was noticed by single-ELISA reactive for anti-HIV. Laboratories with high anti-TP single-ELISA reactive rate were mostly those using combination 4. 【Conclusion】 The HBsAg single-ELISA reactive rate was the highest in the four blood screening items of blood station laboratories in Henan. The single-ELISA reactive rate is related to the laboratory itself and the reagent manufacturer, suggesting that laboratory quality control should be strengthened and proper reagent combination should be selected to reduce the waste of blood.
