ABSTRACT
High quality is the premise for the implementation of high quality and good price for decoction pieces， and grade is the most direct manifestation of high quality of decoction pieces. However， there is still a lack of scientific and reasonable methods for evaluating the grade of decoction pieces， and it is urgent to establish a widely recognized and unified standard for the grade of decoction pieces to ensure the quality of the decoction pieces and guarantee the safety and efficacy of clinical use. Based on this， this paper focused on analyzing the problems of the current grade evaluation methods， such as unclear distinction between quality standards and grade standards， unreasonable selection of grade evaluation indicators， and inaccurate application of mathematical statistical methods. Based on the analysis of the grade evaluation of decoction pieces， this paper proposed four criteria for establishing the grade evaluation method of decoction pieces， namely universality， comprehensiveness， reliability and convenience， in order to establish a more reasonable and unified grade standard for decoction pieces and promote the quality improvement of decoction pieces and the development of the industry.
ABSTRACT
ObjectiveTo investigate the patterns of changes in routine blood parameters， thyroid hormone levels， and their correlations with thyroid peroxidase antibodies （TPOAb） among women at different stages of pregnancy， so as to provide a theoretical basis for maternal and child health care and diagnosis and treatment. MethodsA total of 732 pregnant women at different stages of pregnancy who underwent health examinations at the First Maternity and Infant Hospital affiliated to Tongji University from May 2020 to August 2022 were selected as the observation group. The group comprised 245 women in the first trimester （≤12 weeks）， 247 women in the second trimester （between13 and 27 weeks） and 240 women in the third trimester （≥28 weeks）. Additionally， 240 non-pregnant， healthy women of child-bearing age who conducted their health checkups in the same hospital were selected as the control group. All the research subjects were required to provide peripheral venous blood samples to measure hemoglobin （Hb）， standard deviation of red blood cell distribution width （RDW-SD）， coefficient of variation of red blood cell distribution width （RDW-CV）， platelet （Plt） count， platelet distribution width （PDW）， as well as thyroid stimulating hormone （TSH）， total thyroxine （TT4）， total triiodothyronine （TT3）， free thyroxine （FT4）， free triiodothyronine （FT3）， and TPOAb. The results were statistically analyzed. ResultsWith advancing gestational age， Hb levels were significantly lower in the second and third trimesters than in the first trimester and the control group （F=68.25， P<0.001）， while RDW-SD and RDW-CV were significantly higher （F=41.34， P<0.001； F=3.64， P=0.012）. Plt levels throughout pregnancy were significantly lower than that in the control group （F=43.21， P<0.001）. TSH levels were significantly lower in the first and second trimesters than in the control group （Z=53.49， P<0.001）， but gradually increased with gestational age. TT3 and TT4 levels were significantly higher than those in the control group throughout pregnancy （F＝148.25， P<0.001； F＝210.83， P<0.001）， while FT3 and FT4 levels were significantly lower in the second and third trimesters than in the first trimester and the control group （F=42.95， P<0.001； F=101.73， P<0.001）. The abnormal rate of TPOAb was significantly higher than that in the control group throughout pregnancy （χ2＝25.61， P<0.001）. Among pregnant women， those with TPOAb positivity had significantly higher TSH levels and RDW-CV than those with TPOAb negativity （Z＝5.70， P<0.001； t＝2.39， P＝0.018）. ConclusionThe levels of Hb， Plt， and thyroid hormones in pregnant women are closely related to gestational age. With increasing gestational age， the abnormal rate of TPOAb decreases， but the TSH levels and RDW-CV of TPOAb positive pregnant women are higher， requiring clinical attention and screening to improve maternal and child health.
ABSTRACT
ObjectiveTo compare the differences in thyroid hormone levels between adolescents with and without suicidal ideation， and to explore the association between thyroid hormone/suicidal ideation and the antidepressant treatment. MethodsA total of 100 patients were divided into non-suicidal ideation group and suicidal ideation group according to the SIOSS. The levels of thyroid-stimulating hormone （TSH）， triiodothyronine （T3）， thyroxine （T4）， free triiodothyronine （FT3） and free thyroxine （FT4） were compared between the two groups as well as their changes after 6 weeks of antidepressant treatment. ResultsThe levels of FT3， FT4 and T4 in the non-suicidal ideation group were higher than those in the suicidal ideation group. After 6 weeks of antidepressant treatment， the levels of FT3， FT4 and T4 in the suicide ideation group were higher than those before the treatment. The FT3 level in the male non-suicidal ideation group was higher than that in the suicidal ideation group. The levels of FT4 and T4 in the female non-suicidal ideation group were higher than those in the suicidal ideation group （all P<0.05） ConclusionThere are differences in thyroid hormone levels between adolescents with and without suicidal ideation （both with first-episode depression）， and patients with suicidal ideation have significant changes after treatment with antidepressants.
ABSTRACT
Objective:To explore the impact of different dimensions of cognitive emotion regulation strategies on adolescents with unipolar depression and bipolar depression.Methods:From June 2019 to July 2021, a total of 216 adolescents with depressive disorder were selected, including 134 patients in unipolar depression group, 82 patients in bipolar depression group, and 111 normal controls were selected at the same time.Hamilton depression scale (HAMD), Hamilton anxiety scale (HAMA) and cognitive emotion regulation questionnaire (CERQ) were used to evaluate the emotional symptoms and cognitive emotion regulation strategies of all enrolled subjects. SPSS 23.0 was used for statistical analysis of the data. Kruskal-Wallis rank sum test and multiple Logistic regression analysis were used for statistical analysis.Results:There were significant differences in the dimensions of cognitive emotion regulation strategies and emotional symptoms among the three groups (all P<0.01). The scores of self-blame (14.00(12.00, 17.00), 13.50(12.00, 16.00), 12.00(11.00, 12.00)), rumination (15.00(12.00, 19.00), 14.00(12.00, 17.00), 12.00(10.00, 13.00)) and catastrophizing (13.00(11.00, 17.00), 12.00(9.00, 16.00), 8.00(6.00, 12.00)) in bipolar depression group and unipolar depression group were significantly higher than those in normal control group (all P<0.01). The score of blaming others (11.00(8.75, 13.25), 9.00(8.00, 12.00)) in bipolar depression group was significantly higher than that in normal control group ( P<0.01). The score of positive reappraisal (12.00(12.00, 15.00), 11.00(8.75, 13.00)) in normal control group was significantly higher than that in unipolar depression group ( P<0.01). The putting into perspective score(10.00(8.00, 12.00), 12.00(10.00, 13.25), 12.00(10.00, 13.00)) of normal control group was significantly lower than those of unipolar depression and bipolar depression group (both P<0.01). The scores of HAMD (25.00(22.00, 26.25), 23.00(18.00, 28.00), 3.00(0, 6.00)) and HAMA (17.00(14.00, 21.00), 20.00(16.00, 27.00), 1.00(0, 3.00)) both in unipolar depression group and bipolar depression group were significantly higher than that in normal control group (both P<0.01). Multivariate Logistic regression analysis showed that self-blame, rumination, and catastrophizing were risk factors for unipolar depression ( OR=1.19, 95% CI=1.05-1.35; OR=1.17, 95% CI= 1.06-1.30; OR=1.14, 95% CI=1.02-1.27) and bipolar depression( OR=1.30, 95% CI=1.14-1.50; OR=1.21, 95% CI=1.07-1.36; OR=1.13, 95% CI=1.01-1.28) compared to normal controls, while positive reappraisal were protective factors for unipolar depression ( OR=0.83, 95% CI=0.73-0.95) and bipolar depression ( OR=0.84, 95% CI=0.73-0.98). However, after controlling for HAMD, HAMA and gender, the effects of each dimension of cognitive emotion regulation strategies on unipolar depression and bipolar depression were no longer significant(both P>0.05). Conclusion:The negative cognitive emotion regulation strategies are correlated with the risk of disease in adolescents with unipolar and bipolar depression, and this effect is affected by the patients' own depression, anxiety and other factors.

ABSTRACT
Combining the psychological "big data" of college students with the data of the psychological expert database, using data mining algorithm to extract characteristic attributes, deriving the warning results from a stable algorithm model, the psychological early warning platform constructed by this method can not only monitor students' psychological dynamics in real time, but also predict their psychological behavior trend, which makes up for the lag and low accuracy of traditional early warning methods. The psychological early warning platform provides data support and the psychological early warning system provides operational guarantee. The psychological early warning mechanism formed by the combination of the two can provide scientific basis for educators and finally achieve the goal of using big data technology to improve the mental health of college students.
ABSTRACT
Objective@#Empirical findings confirmed that autistic and schizotypal traits are associated with attentional function as well as include various dimensions. So far, no study has reported which dimension of these traits relates to attentional networks. This study aimed to find out whether there are associations between attentional networks and autistic traits; and between attentional networks and schizotypal traits. @*Methods@#A total of 449 volunteers was included in this study, and autism-spectrum quotient (AQ), schizotypal personality questionnaire (SPQ), and attention network test (ANT) were used to measure autistic traits and schizotypal traits. The three independent attentional networks, including alerting network, orienting network, and executive control network, were also measured. @*Results@#Autistic traits were associated with the orienting network, whereas schizotypal traits were associated with the orienting network and executive control network. Furthermore, attentional networks could be predicted by specific dimensions of autistic and schizotypal traits. AQ-attention switching [0.104 (-1.175– -0.025), p=0.041] and AQ-attention to detail [-0.097 (-0.798– -0.001), p=0.049] were significant predictors of orienting network and gender were significant predictor of executive network (Beta=0.107; 95% CI=-0.476–10.139; p=0.031). Whereas, schizotypal dimension “interpersonal” was a significant predictor of all three attentional networks [Alerting: 0.147 (-0.010–0.861), p=0.045; Orienting: 0.147 (0.018–0.733), p=0.040; Executive: 0.198 (0.215–1.309), p=0.006]. @*Conclusion@#This study demonstrated that autistic and schizotypal traits were associated with attentional networks. The specific dimensions of autistic and schizotypal traits could predict attentional networks. Nevertheless, the attentional networks predicted with these two traits were different.

ABSTRACT
Objective:To investigate the relationship of mitochondrial DNA (mtDNA) copy number with clinicopathologic characteristics and its influence on the prognosis of hepatocellular carcinoma (HCC) patients.Methods:The retrospective case-control study was conducted. The clinicopathological data of 71 HCC patients undergoing surgical treatment in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University from March to June 2011 were collected. There were 61 males and 10 females, aged from 26 to 80 years, with a median age of 55 years. The mtDNA copy number of tumor tissues and adjacent normal tissues were measured for all patients. Observation indicators: (1) the mtDNA copy number of tumor tissues and adjacent normal tissues and relationship between the mtDNA copy number and clinicopathological characteristics of HCC patients; (2) follow-up; (3) related factors for the prognosis of HCC patients. Follow-up using outpatient examination or telephone interview was conducted to detect postoperative survival of patients up to September 2019. Measurement data with normal distribution were described as Mean± SD, and comparison between groups was analyzed using independent samples t test or the matched samples t test. Measurement data with skewed distribution were described as M(range). Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Univariate and multivariate analyses were conducted using the COX regressional model. Variables with P<0.10 in the univariate analysis were included for the multivariate analysis. Survival rates were calculated using the Kaplan-Meier method, and Log-rank test was used for survival analysis. Results:(1) The mtDNA copy number of tumor tissues and adjacent normal tissues and relationship between the mtDNA copy number and clinicopathological characteristics of HCC patients: of 71 HCC patients, the mtDNA copy number was 0.85±0.08 in tumor tissues, versus 1.16±0.08 in adjacent normal tissues, showing a significant difference between them ( t=2.96, P<0.05). Of 71 HCC patients, 48 cases were mtDNA-low and 23 cases were mtDNA-high. Cases with tumor capsule as integrity or not-integrity, cases with or without microvascular (MVI) in mtDNA-low and mtDNA-high patients were 20, 28, 21, 27 and 16, 7, 4, 19, respectively, showing significant differences ( χ2=4.84, 4.74, P<0.05). (2) Follow-up: 71 patients were followed up for 2.1 to 85.3 months, with a median follow-up time of 47.8 months. The 1-, 3-, 5-year overall survival rates of 71 HCC patients were 87.3%, 64.7, 37.4%, respectively. Moreover, the 1-, 3-, 5-year overall survival rates were 81.2%, 50.0%, 29.2% of the mtDNA-low patients, versus 95.7%, 86.5%, 54.7% of the mtDNA-high patients, showing a significant difference between the two groups ( χ2=5.86, P<0.05). (3) Related factors for the prognosis of HCC patients. Results of univariate analysis showed that the number of tumor, portal vein tumor thrombus, MVI, Barcelona Clinic Liver Cancer stage, mtDNA copy number were related factors for the prognosis of HCC patients ( hazard ratios=2.211, 2.911, 3.899, 3.587, 0.440, 95% confidence intervals as 1.024?4.777, 1.485?5.704, 2.115?7.186, 1.615?7.966, 0.223?0.871, P<0.05). Results of multivariate analysis showed that MVI and mtDNA copy number were independent influencing factors for the prognosis of HCC patients ( hazard ratios=2.754, 0.437, 95% confidence intervals as 1.374?5.521, 0.205?0.932, P<0.05). Conclusions:The mtDNA copy number of HCC patients is related with tumor capsule and MVI. The mtDNA copy number and MVI are independent influencing factors for the prognosis of HCC patients.
ABSTRACT
Methyltransferase like 13 (METTL13), a kind of methyltransferase, is implicated in protein binding and synthesis. The upregulation of METTL13 has been reported in a variety of tumors. However, little was known about its potential function in head and neck squamous cell carcinoma (HNSCC) so far. In this study, we found that METTL13 was significantly upregulated in HNSCC at both mRNA and protein level. Increased METTL13 was negatively associated with clinical prognosis. And METTL13 markedly affected HNSCC cellular phenotypes in vivo and vitro. Further mechanism study revealed that METTL13 could regulate EMT signaling pathway by mediating enhancing translation efficiency of Snail, the key transcription factor in EMT, hence regulating the progression of EMT. Furthermore, Snail was verified to mediate METTL13-induced HNSCC cell malignant phenotypes. Altogether, our study had revealed the oncogenic role of METTL13 in HNSCC, and provided a potential therapeutic strategy.

Objective:To develop a novel method for detection of genomic RNA of 2019-nCoV with reverse-transcription thermophilic helicase-dependent amplification (tHDA) and lateral flow dipsticks.Methods:This study included 143 PCR-negative nucleic acid specimens and 20 PCR- positive nucleic acid specimens collected from patients from January to April 2020 at Institute of Clinical Laboratory, Jinling Hospital. 5 pairs of primers were designed for conserved sequence of both gene N and E of 2019-nCoV, and the amplicons were analyzed by gel electrophoresis to screen out the most efficient primers. High level (5×10 5 copies/ml) and low level (5×10 2 copies/ml) templates were amplified, and lateral flow dipsticks (LFD) were used to detect amplification products. The amplification time and visualization time were optimized to visualize the results, and the optimal tHDA-LFD reaction system was established. Simulated specimens with low, medium, and high concentrations were detected for 15 times, and precision was assessed. The limit of detection was evaluated using tenfold serial dilutions of 2019-nCoV in contrived samples. To evaluate the cross-reactivity, six samples of respiratory viruses, including influenza A virus, influenza B virus, human adenovirus, human respiratory syncytial virus, human parainfluenza virus and coronavirus 229E were tested using this assay. The tHDA-LFD assay was performed to detect 2019-nCoV in 163 clinical specimens stored in our laboratory. The clinical diagnostic efficacy was determined. Results:The established RT-tHDA one-step method combined with LFD was adopted, which could be conducted within 60 min and was reproducible with good precision, showing 100% positive concordance rate. The assay showed no cross reaction with other six human respiratory pathogens. The limit of detection of the RT-tHDA assay was 5×10 2 copies/ml for both N and E genes detected by LFD. The diagnostic efficacy evaluation showed that the sensitivity of the method was 95.00%(19/20), and the specificity was 100.00%(143/143). The positive predicted value of the method was 100.00% (19/19)and the negative predicted value was 99.31%(143/144). Compared with real-time RT-qPCR assay, it showed Kappa value of 0.971 ( P<0.0001). Conclusion:The proposed tHDA-LFD assay is a rapid and visualized method to detect 2019-nCoV.
ABSTRACT
Objective:To investigate of AIDET communication model in caring for type 2 diabetes mellitus of hospitalized patients.Methods:A total of 113 patients with type 2 diabetes mellitus treated in our department from January 2018 to November 2019 were enrolled, and divided into the control group(receiving a conventional communication mode)and the observation group(receiving an AIDET communication mode)according to a time order in the selecting of the research patients.The changes of self-care behavior and glucose metabolism index were evaluated and analyzed between the two groups.Results:On admission, the fasting blood glucose, 2-h postprandial blood glucose and glycosylated hemoglobin were(9.1±1.7)mmol/L, (13.8±2.9)mmol/L and(8.4±3.5)% in the observation group, and(9.4±2.1)mmol/L, (14.1±3.2)mmol/L and(8.1±2.9)% in the control group, respectively, with no statistically significances( P>0.05). At discharge, the observation group versus the control group showed a statistically significantly improved levels in FPG of(5.9±1.5)mmol/L vs.(7.8±1.9)mmol/L, in 2h-PBG of(10.1±3.7)mmol/L vs.(12.8±3.9)mmol/L and in glycosylated hemoglobin of(6.3±1.2)% vs.(7.5±0.9)%, respectively( P<0.05). The scores of management of poor blood glucose, foot care, blood glucose monitoring, medication compliance, regular exercise and diet control were higher in the observation group than in the control group at discharge( P<0.05). Conclusions:The application of AIDET communication mode can effectively enhance the self-care behavior of patients and help improve the glucose metabolism in hospitalized patients with type 2 diabetes mellitus.It has very positive effects on controlling the development of type 2 diabetes mellitus and improving the quality of life.
ABSTRACT
Objective:To evaluate the association between the efficacy and safety of metformin and the influence of variants in SLC47A1 rs2289669 G>A polymorphism in the treatment of systemic lupus erythematosus (SLE).Methods:A multicenter, randomized, double-blind, placebo-controlled trial was conducted. Patients were consented at enrollment for blood donation for genotyping, and their peripheral blood were used to detect the distribution frequency of SLC47A1 mutations. The major or mild/moderate flares defined by modified safety lupus erythematosus national assessment (SELENA)-systemic lupus erythematosus disease activity index (SLEDAI) Flare Index (SFI) and adverse events were recorded at 12 months of follow-up. The correlation between efficacy/safety and genotype was analyzed. Student's t test and χ2 test was used to assess the continuous variables and categorical variables. Results:Between May 24, 2016, and Dec 13, 2017, a total of 31 patients in the metformin group and 35 in the placebo group were detected. There were no statistical significant differences in the clinical manifestations, SELENA-SLEDAI scores, and therapy of the participants at baseline. There was no significant difference in the frequency of AA genotype, GA genotype, and GG genotype of SLC47A1 rs2289669 distribution between the metformin group and the placebo group. In the metformin group, patients who flared had a lower frequency of A alleles than those non-flared [25%(4/16) vs 61%(28/46), χ2=6.116, P=0.019 8]; the flare rate was significantly lower in patients with AA genotype than in GG genotype [0%(0/8) vs 57%(4/7), χ2=6.234, P=0.012 5]. The infection rate was lower in the metformin group than that in the placebo group [38%(12/31) vs 69%(24/35), χ2=5.913, P=0.015 0], but there was no significant difference among different genotypes in the metformin group. Compared to GG geno-type, AA genotype showed a trend of decrease in infection rate[38%(3/8) vs 72%(5/7), χ2=1.727, P=0.188 8]. Conclusion:Metformin has a favorable safety profile and may reduce the frequency of flares in SLE patients with low-grade lupus disease activity. The metformin therapeutic efficacy in SLE is relevant to the SLC47A1 gene polymorphism. Patients of the AA genotype may benefit most from metformin than those of the GG and GA genotypes.
ABSTRACT
To prevent and control the epidemic of coronavirus disease 2019 (COVID-19), the community health service center should take the initiative to cooperate with sub-district office and police station to form a joint working team. Taking the advantages of professional expertise and using service contract system, the general practitioners can publicize the epidemic prevention knowledge and self-protection methods among community residents; and also take door-to-door inspection to make the decision of home isolation, centralized isolation, fever clinic visit or transfer to the designated hospital for observation and treatment. During the COVID-19 epidemic, we should give full play to the enthusiasm initiative of the community, general practitioners and residents to implement prevention and control measures and to ensure the health and safety of the people.

ABSTRACT
Primary bile acids were reported to augment secretion of chemokine (C‒X‒C motif) ligand 16 (CXCL16) from liver sinusoidal endothelial cells (LSECs) and trigger natural killer T (NKT) cell-based immunotherapy for liver cancer. However, abundant expression of receptors for primary bile acids across the gastrointestinal tract overwhelms the possibility of using agonists against these receptors for liver cancer control. Taking advantage of the intrinsic property of LSECs in capturing circulating nanoparticles in the circulation, we proposed a strategy using nanoemulsion-loaded obeticholic acid (OCA), a clinically approved selective farnesoid X receptor (FXR) agonist, for precisely manipulating LSECs for triggering NKT cell-mediated liver cancer immunotherapy. The OCA-nanoemulsion (OCA-NE) was prepared

Objective@#To investigate the effects of preoperative percutaneous transhepatic biliary drainage on surgical treatment of type Ⅲ and Ⅳ hilar cholangiocarcinoma.@*Methods@#Clinical data of 72 patients with hilar cholangiocarcinoma of the Bismuth-Corlette type Ⅲ and Ⅳ treated at Department of General Surgery,First Affiliated Hospital of Bengbu Medical College from January 2010 to December 2017 were analyzed retrospectively.Patients were divided into two groups based on whether PTBD was performed:a drained group and an undrained group.In the drained group,there were 31 patients,20 males and 11 females,aged (59.9±9.7)years (range: 39-73 years).Among them,14 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 17 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).In the undrained group,there were 41 patients, 26 males and 15 females, aged (60.8±7.8)years(range: 45-75 years).Among them, 17 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 24 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).Percutaneous transhepatic biliary drainage(PTBD)was used in the drained group.Under the guidance of ultrasound,one or more hepatobiliary ducts could be sufficiently drained,which had good effect and was not restricted by the obstruction location of hilar cholangiocarcinoma.The analysis of the measurement data was performed using t test,and the analysis of the count data was performed using χ2 test,and the survival curve was plotted using Kaplan-meier method.@*Results@#In total, 72 jaundiced patients with hilar cholangiocarcinoma underwent surgical treatment: 31 had PTBD prior to operation while 41 did not had PTBD.There were significant differences in ALT((93.2±21.4)U/L vs.(207.4±65.1)U/L),AST((87.6±18.1)U/L vs.(188.9±56.6)U/L)and total bilirubin((68.8±12.6)μmol/L vs.(227.5±87.7)μmol/L)between the patients after treatment and those before treatment(t=10.958, P=0.000; t=10.845, P=0.000; t=10.386, P=0.000).Compared with those in the undrained group, the operation time was shorter, the amount of intraoperative bleeding and the incidence of complications were lower in the drained group(t=-2.840, P=0.006; t=-3.698, P=0.000; χ2=4.108, P=0.043).There were no perioperative death cases in drained group and 2 perioperative death cases in undrained group.There was no significant difference in R0 resection rate between the two groups(χ2=0.778,P=0.378).The 1-,3-,5-year survival rate of patients in the drained group and the undrained group was 72.7%,34.2%, 13.7% and 72.8%, 31.5%, 11.8%, respectively.The difference was not statistically significant(all P>0.05).@*Conclusions@#The preoperative percutaneous transhepatic biliary drainage in patients with hilar cholangiocarcinoma of Bismuth-Corlette type Ⅲ and Ⅳ could effectively shorten operative time, reduce amount of intraoperative bleeding and incidence of postoperative complications,but have no significant effect on the R0 resection rate and survival rate.
ABSTRACT
Internet gaming disorder (IGD) refers to individuals who are extremely dependent on online games and can’t control the game time reasonably.Generally, individuals with IGD also display withdrawal symptoms when they do not play games.Combined with previous studies, this paper discussed the cognitive dysfunction and neural mechanisms of IGD individuals, including executive function, reward system and emotional regulation dysfunction.First of all, executive function is a high-level cognitive processing ability that involves cognitive and behavioral processes.Cognitive control is often associated with the individual's goal-directed behavior and the ability to flexibly apply the high-level cognitive function. Repeated and excessive game behaviors of IGD individuals may be associated with their abnormal cognitive control and decision-making functions. And the attention process as another important component of executive function. The persistent addictive behavior in individuals with IGD were associated with a bias toward attention to game-related cues.Also, IGD individuals show differences in executive function abnormalities such as decision-making and dominance response inhibition, suggesting that there is a separation between "cold" and "hot" executive function abnormalities, and this feature may also be associated with other cognitive dysfunctions. Secondly, reward incentives play an important role in individual motivational learning and goal-oriented behavior. The increased sensitivity of IGD individuals to reward stimuli in various types of reward and punishment stimuli suggests that their reward system is abnormal.Finally, emotional regulation is an important cognitive function that is closely related to executive function. The anxiety and depression manifested by IGD individuals are often associated with their inability to apply emotional regulation strategies flexibly. It is difficult for individuals with IGD applied emotional regulation strategies flexibly, and inappropriate emotional regulation strategies and emotional responses suggest abnormal mood regulation. To sum up, cognitive dysfunction was not only the basis of IGD addiction symptoms, but also one of the important factors of its symptom maintenance. In addition, the further research prospects included expanded sampling population, deepening neural mechanism research and physical intervention are proposed for the lack of previous research in the last part of the article.
