ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective To investigate the value of ¹⁸F-FDG PET/CT metabolic parameters in the prognostic assessment of nasopharyngeal cancer patients. Methods The clinical data and PET/CT metabolic parameters of 185 nasopharyngeal cancer patients were retrospectively analyzed. The collected parameters were SUV_max, MTV, TLG, total metabolic tumor volume (TMTV) and whole-body total lesion glycolysis (WTLG). The ROC curve was used to determine the optimal cut-off values of PET/CT metabolic parameters. Univariate and multivariate Cox regression models were used to screen the independent prognostic factors. Kaplan–Meier curves were used to analyze the survival differences. Results The results of univariate Cox regression analysis showed that age, pathologic type, WTLG, TMTV, MTV, and TLG were closely associated with OS and PFS; and SUV_max was associated with PFS (P<0.05). Multivariate Cox regression analysis results showed that age, TMTV, and WTLG were the independent prognostic factors for OS and PFS (P<0.05). The combination of WTLG with T/N staging (AUC=0.781 and 0.781) and TMTV with T/N staging (AUC=0.800 and 0.790) yielded greater predictive accuracy than that of WTLG and TMTV alone (AUC=0.724 and 0.719) or T/N staging (AUC=0.593 and 0.575). Conclusion TMTV and WTLG are important prognostic predictors of nasopharyngeal carcinoma. TLG and MTV of primary lesions are prognostic factors for patients’ PFS and OS. SUV_max has limited prognostic value. Systemic metabolic indexes (TMTV and WTLG), when combined with T/N staging, can optimize prognostic stratification.

Objective: To analyze the status and correlation between screen time, screen behavior type, and anxiety, depression among children and adolescents in Jiangxi Province, so as to provide a basis for effective intervention measures. Methods: Using the method of stratified random sampling, 8 851 primary and secondary school students in 11 districts of Jiangxi Province were investigated by questionnaire during September to December in 2020. Anxiety and depression status were investigated using the State Trait Anxiety Inventory (STAI) and the Center for Epidemiological Studies Depression Scale for Children(CES-DC), respectively. Single factor analysis using χ 2-test, t-test,analysis of variance,and multivariate analysis using generalized linear models. Results: On school days and weekends, 4.7% and 20.4% of primary and secondary school students in Jiangxi Province had a total screen time of over 2 hours per day, respectively. The weighted scores of the total screen time (primary school students: 1.88± 0.68, junior middle school students: 1.96±0.71, high school students: 2.03±0.80) and time spent for playing video games (primary school students: 1.51±0.64, junior middle school students: 1.62±0.69, high school students: 1.68±0.75) daily showed an upward trend with the increase of educational stage ( F =31.48, 42.13), and with significantly higher in boys (1.97±0.74, 1.66± 0.72) than girls (1.93±0.72, 1.53±0.66)( t =2.48, 9.07)( P <0.05). The average scores of state anxiety and trait anxiety were (42.20±9.05) and (40.65±9.85), which showed an upward trend with the increase of educational stage ( F =168.12, 241.98 ), and were higher in girls than boys ( t =6.63, 8.48)( P <0.01). The average score of depression was (11.99±11.00), which was lower in elementary school students than middle school students and high school students ( F =136.42), with significantly higher in girls ( t =6.85)( P <0.01). On school days, with the increase of total screen time and time spent for playing video games daily, the risk of state anxiety, trait anxiety, and depression among primary and secondary school students significantly increased ( OR = 6.70- 818.98, P <0.01). On weekends, among primary and secondary school students, the total screen time of >1-2 hours daily reduced the risk of state anxiety ( OR =0.30). The risk of developing trait anxiety among students playing video games for more than 2 hours daily was 2.50 times higher than those without screen behavior ( OR =2.50). The risk of developing depression with a total screen time of more than 2 hours daily was 3.15 times higher those whithout screen behavior ( OR =3.15). The risk of developing depression among students playing video games >0-1, >1-2, >2 h daily was 2.14, 2.50, 4.90 times that of those without screen behaviors ( OR =2.14, 2.50, 4.90), and showed an upward trend with the increase of educational stage ( P <0.05). Conclusions Screen behaviors of primary and middle school students in Jiangxi Province are positively associated with the risk of anxiety and depression, but the total daily video time of >1-2 h on weekends was negatively associated with state anxiety. It is necessary to control the screen time as much as possible and reduce the risk of anxiety and depression.

Ulcerative colitis （UC） is a chronic， non-specific inflammatory bowel disease. The pathogenesis of this disease is complex and is attributed to multiple factors. Intestinal mucosal barrier damage is the basic pathological change of UC， and intestinal flora disorder is one of the important characteristics of UC. Intestinal flora plays a key role in the pathological process of UC by regulating intestinal mucosal immunity and inflammatory response to repair the damaged intestinal mucosal barrier. At present， western medicine has the advantages of rapid action onset and significant short-term efficacy， but the curative effect of long-term use is not good， accompanied by many adverse reactions， causing great physical and mental pain to patients. Therefore， it is urgent to explore new treatment methods with definite long-term efficacy and mild adverse reactions. A large number of studies have shown that Chinese medicine can regulate intestinal flora through multiple targets in an all-around way， restore the homeostasis of the flora， and repair the damaged intestinal mucosal barrier， thereby inhibiting the progression of UC. Numerous studies have shown that the active components， monomers， and compounds of Chinese medicine can effectively antagonize UC by regulating the intestinal flora to improve the intestinal mucosal immunity， reduce the inflammatory response of the intestinal mucosa， and restore the normal physiological function of the intestinal mucosal barrier， providing a new strategy for UC prevention and treatment. Although there are some studies of the regulation of intestinal flora by Chinese medicine to prevent and treat UC， those studies have the shortcomings of systematic and comprehensive inadequacy. Therefore， based on the research status of UC， intestinal flora， and Chinese medicine treatment， this study reviewed the relationship between intestinal flora and UC and clarified the key role of intestinal flora in the occurrence and development of UC. At the same time， this paper comprehensively summarized the Chinese medicine that targeted the regulation of intestinal flora for the treatment of UC in the past five years to provide new strategies and ideas for UC treatment.

Ulcerative colitis （UC） is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease， due to a combination of factors， is complex and has not yet been elucidated. Among them， intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells， autophagy regulates intestinal mucosal immunity， inflammation， oxidative stress， and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier， exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations， glucocorticoids， and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect， and the short-term efficacy is definite， but the long-term application is easy to be accompanied by more adverse reactions. Moreover， some drugs are expensive， bringing great physical and mental pain and economic burden to patients. Therefore， it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years， a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function， thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa， inflammation， oxidative stress， and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC， providing a new measure for the prevention and treatment of UC. However， there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore， based on the current research on UC， autophagy process， and Chinese medicine treatment， this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.

ObjectiveTo analyze the clinical characteristics and the use of traditional Chinese medicine （TCM） therapy in cancer patients with COVID-19， and to provide reference for making TCM prevention and treatment strategies and determining diagnosis and treatment priorities for patients with malignant tumors in the COVID-19 epidemic. MethodsThe medical records of 225 malignant tumor cases with COVID-19 who were admitted to 7 national research centers from January 1st to 20th， 2023 were retrospectively collected， and the main symptoms and duration after infection， nucleic acid negative conversion time， use of TCM therapy， and changes in adverse reactions after resuming anti-tumor treatment were analyzed. ResultsA total of 222 malignant tumor patients with COVID-19 were included in the analysis， involving 205 mild cases and 17 moderate cases. The top four most frequently reported clinical symptoms were fever （165 cases）， expectoration or dry cough （99 cases）， decreased appetite （95 cases） and fatigue （85 cases）， of which 40 expectoration or dry cough cases ， 37 fatigue cases and 29 decreased appetite cases lasted for more than 14 days. One hundred and five patients with nucleic acid detection report had a median negative conversion time of 14 days. The nucleic acid negative conversion time was significantly longer in patients with lung cancer compared to those with digestive system malignant tumors， and in those with myelosuppression than those without （P＜0.01）. During the infection period， 47.30% （105/222） of the patients used Chinese patent medicine， and 21.17% （47/222） were treated with herbal decoctions. The use of TCM in patients during the prevention and rehabilitation period， was 1.80%（4/222） and 7.21%（16/222）， respectively. Fifty-five patients resumed anti-tumor treatment after nucleic acid negative conversion， and received TCM simultaneously. Observed adverse reactions， including gastrointestinal reactions， bone marrow suppression， and neurotoxicity， were all grade 1 to 2， and no new adverse events occurred during follow-up. ConclusionCertain malignant tumor patients with COVID-19 had prolonged symptoms and nucleic acid negative conversion time Rational use of TCM can help to promote the rehabilitation of the patients and ensure the smooth process of anti-tumor treatment after infection.

【Objective】 To investigate the current situation of social anxiety in children with attention deficit hyperactivity disorder (ADHD), and to analyze the factors influencing social anxiety in ADHD children, in order to provide reference for improving the clinical management of ADHD children. 【Methods】 A total of 206 school-age children with ADHD were selected from the Children′s Psychology Clinic of Mianyang Central Hospital from January 2020 to January 2023. The relevant clinical data of the children were collected through the general data questionnaire. Children′s Social Anxiety Scale (SASC) was used to assess social anxiety, and the Social Response Scale (SRS) was used to assess social ability. The Chinese version of Swanson,Nolan and Pelham Rating Scale Ⅳ (SNAP-Ⅳ) was used to assess core symptoms. Multivariate Logistic regression analysis was used to determine influencing factors of social anxiety in children with ADHD. 【Results】 There were 128(62.14%) cases detected with social anxiety among 206 children with ADHD. The score of SASC was 14.02±4.06. The proportions of girls (χ²=6.057), comorbid autism spectrum disorder(ASD) (χ²=4.929), and main caregivers with junior high school education or below (χ²=13.345), the total score of SRS(t=5.842) and SNAP-Ⅳ(t=7.848) and the scores of all dimensions were significantly higher than those in the non-anxious group (P<0.05). Multivariate Logistic regression analysis showed that higher SRS total score(OR=5.217, 95%CI: 2.309 - 11.791), higher SNAP-Ⅳ total score(OR=4.150, 95%CI: 1.974 - 8.722), girls(OR=2.268, 95%CI: 1.423 - 3.616), primary caregivers with junior high school education or below (OR=1.527, 95%CI: 1.162 - 2.005), and comorbid ASD (OR=1.551, 95%CI: 1.209 - 1.990) were risk factors for social anxiety in ADHD children (P<0.05). 【Conclusions】 Children with ADHD have a higher prevalence rate of social anxiety. Cognitive behavioral therapy and psychological intervention should be strengthened for high-risk children to improve social ability and reduce the risk of social anxiety.

Multisystem inflammatory syndrome in children is a disease related with severe acute respiratory syndrome corona-virus 2 infection,which can involve multiple system damage.Most cases included features of shock,cardiac dysfunction,gastrointestinal symptoms,significantly elevated markers of inflammation and cardiac damage,and positive test results for SARS-CoV-2 by serology.Although its clinical features overlap with Kawasaki disease,it is more likely to occur in older children and adolescents,and most of them need to be treated with intensive care and a variety of immunomodulators.At present,the pathogenesis and long-term prognosis of the disease need to be further studied.

ObjectiveTo analyze the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Zhangjiakou City, Hebei Province from 2013 to 2022, so as to provide a basis for HFMD prevention, control, and evaluation of intervention effectiveness. MethodsHFMD data of Zhangjiakou City from 2013 to 2022 were collected. Descriptive statistics and the Joinpoint regression model were used to analyze the trend of the epidemic. ResultsThe incidence of HFMD in Zhangjiakou was predicted to decrease with APC=-14.86% in 2013‒2022. The top five regions with the highest incidence showed varying trends: Qiaodong District (APC=-26.21%), Qiaoxi District (APC=-18.29%), Xuanhua District (APC=-14.28%), Chicheng District (APC=-18.68%), and Zhuolu County (APC=51.43% in 2013‒2016, APC=-14.27% in 2016‒2022), indicating a downward trend. Three age groups showed an upward trend in incidence: the 0-year-old group (APC=-42.82% in 2013‒2016, APC=16.54% in 2016‒2022), the 7-year-old group (AAPC=9.60%), and the 9-year-old group (AAPC=12.76%). HFMD cases occurred throughout the year, peaking from June to August, with July being the most significant month. The male-to-female ratio was1.40∶1, with no statistical difference (χ²=5.932, P>0.05). A high incidence was in children under 5 years old, with those aged 1‒4 years being the main affected group. In terms of occupation, scattered children (6 245 cases, 57.65%) and preschool children (3 653 cases, 33.72%) were the most affected. A total of 504 laboratory-confirmed cases were reported, with a detection rate of 4.65% (504/10 832). The composition of confirmed cases included CoxA 16 (193 cases, 38.29%), EV71 (75 cases, 14.88%), and other enteroviruses (236 cases, 46.83%). ConclusionFrom 2013 to 2022, HFMD in Zhangjiakou City showed a downward trend with clear seasonal, regional, and occupational distributions. It is suggested that epidemic monitoring should be strengthened, etiological detection should be enhanced, and education efforts in key areas should be improved. High-incidence counties should analyze data and conduct risk assessments effectively.

Objective: To explore the association of the interaction between vitamin D deficiency and dyslipidemia with the comorbidity risk of overweight and obesity in children and adolescents, so as to provide the theoretical basis for prevention and control of overweight and obesity in children and adolescents. Methods: The data for the study was obtained from the population aged 6-17 in Hebei Province during the 2022-2023 monitoring of nutrition and health status of Chinese residents. A stratified cluster random sampling method was used to conduct questionnaire surveys, physical measurements, and laboratory tests on 2 118 children and adolescents. Logistic regression was used to analyze the association of vitamin D deficiency and dyslipidemia with overweight and obesity, and multiplication and addition models were used to analyze the interaction of vitamin D deficiency and dyslipidemia with overweight and obesit. Results: The prevalence of vitamin D deficiency in the surveyed children and adolescents was 67.80%, the incidence of dyslipidemia was 24.46%, and the prevalence of overweight and obesity was 41.97%. After adjusting for confounding factors, the results of multivariate Logistic regression analysis showed that there was no multiplicative interaction of vitamin D deficiency and dyslipidemia with overweight and obesit ( OR=0.90, 95%CI=0.57-1.43, P >0.05). However, the risk of overweight and obesity among children and adolescents with vitamin D deficiency and dyslipidemia was 3.99 times higher than that of those with sufficient vitamin D and normal blood lipids ( OR=3.99, 95%CI=2.93-5.45, P <0.01). There was a positive additive interaction between vitamin D deficiency and dyslipidemia, with relative excess risk of interaction, attributable proportion of interaction and synergy index of 14.40, 81.50% and 7.35, respectively. Conclusions For children and adolescents, there is a synergistic effect between vitamin D deficiency and dyslipidemia, and the coexistence of both increases the risk of overweight and obesity. Comprehensive prevention and control measures should be taken to timely supplement vitamin D and maintain normal blood lipid levels, to reduce the occurrence of overweight and obesity in children and adolescents.
