ABSTRACT
Sanggenon C is a kind of flavonoid compound mainly extracted from the traditional Chinese medicine Morus alba. The pharmacological effects and mechanisms of sanggenon C are systematically reviewed and summarized， and it is found that this component can improve pulmonary fibrosis by regulating transforming growth factor-β1 and nuclear factor-κB； it can exert anti- tumor effects by inhibiting the proliferation of tumor cells and inducing the apoptosis of tumor cells； it can exert cardioprotective， neuroprotective and hepatoprotective effects by regulating multiple signaling pathways， such as calcineurin/nuclear factor of activated T cells 2， peroxisome proliferators-activated receptor α， and Ras homolog gene family member A/Rho-associated coiled- coil containing protein kinase， enhancing autophagy， reducing inflammatory response and reducing the level of oxidative stress； it can treat osteoporosis by inhibiting osteoclast uptake and promoting osteoblast formation； it has certain inhibitory effect on many enzymes； it can exert anti-inflammatory effects by regulating nuclear factor-κB signaling pathway； it can exert antioxidant effects by scavenging free radicals. However， researches on the pharmacological effects of sanggenon C mostly focus on the cellular and animal field， and the specific mechanism of action is not yet clear. In the future， basic research and clinical trials are still needed to explore and verify.
ABSTRACT
BackgroundThere are differences in executive function between major depressive episode patients with or without psychotic symptoms， and childhood trauma may affect the executive function of patients with major depressive episode. Previous research studies predominantly focused on adult patients with major depressive episode， with a lack of studies specifically focusing on adolescent patients with major depressive episode. ObjectiveTo investigate the differences in executive function among adolescent patients with major depressive episode， with or without psychotic symptoms and childhood trauma. MethodsA total of 112 hospitalized adolescent patients with major depressive episode who met the criteria of the International Classification of Diseases， tenth edition （ICD-10） were included in the study. The participants were recruited from the Department of Child and Adolescent Psychiatry， Shenzhen Kangning Hospital during the period from August 2020 to November 2021. Additionally， 27 healthy controls were recruited through public advertisements. The Cambridge Neuropsychological Test Automated Battery （CANTAB） was used to assess executive function through the administration of the Motor Screening Task （MOT）， Spatial Working Memory（SWM） and Rapid Visual Information Processing （RVP） modules. Childhood Trauma Questionnaire-Short Form （CTQ-SF） was used to assess the trauma type. ResultsCompared with healthy controls， adolescent patients with major depressive episode had a longer mean delay （Z=-3.407， P=0.001） in the MOT task. In the SWM task， the patients had a higher total number of intergroup error responses （Z=-3.291， P=0.001）， a higher total number of intragroup error responses （Z=-3.461， P=0.001）， more total number of double error responses （Z=-3.218， P=0.001）， a higher total error responses （Z=-3.312， P=0.001）， higher strategy scores （Z=-2.437， P=0.015） and longer average delay time （Z=-2.055， P=0.040）. In the RVP task， the patients had fewer hits （Z=-3.196， P=0.001）， more misses （Z=-3.179， P=0.001）， fewer rejections （Z=-2.772， P=0.006）， lower hit probability （Z=-3.187， P=0.001） and lower A´ scores （Z=-3.070， P=0.002）.Compared with adolescent patients with major depressive episode without psychotic symptoms， those with psychotic symptoms had a lower total number of double error responses （Z=-2.566， P=0.010） in SWM task. Compared with adolescent patients with major depressive episode who did not experience emotional neglect， those who experienced emotional neglect had longer average delay time （Z=-3.183， P=0.001） in MOT task， fewer total hits （Z=-2.445， P=0.014）， more total missed reports （Z=-2.467， P=0.014）， lower hit probability （Z=-2.445， P=0.014） and lower A´scores （Z=-2.089， P=0.037） in RVP task. Adolescent patients with major depressive episode who had experienced emotional abuse had longer average delay time in MOT task than those who had not experienced emotional abuse （Z=-2.552， P=0.011）. ConclusionAdolescent patients with major depressive episode exhibit abnormalities in a majority of executive function domains. Specifically， those without psychotic symptoms and with childhood trauma demonstrate significantly impaired executive function. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGS013）， Basic and Applied Basic Research Fund of Guangdong Province （number， 2019A1515110047）， Shenzhen Science and Technology Planning Project （number， JCYJ20190809155019338）］
ABSTRACT
Objective:To investigate the effect of prospective intervention on emergence agitation and postoperative recovery in patients with chronic sinusitis during preoperative visits.Methods:A total of 80 patients with chronic sinusitis who underwent general anesthesia in Dayi County People′s Hospital of Chengdu City from December 2019 to October 2020 were selected and randomly divided into group D and group G, with 40 patients in each group. Group D received preoperative visit with conventional methods and group G received preoperative visit with prospective intervention methods. The hemodynamic changes of patients in the two groups at 30 min before the operation (T 1) and 1 (T 2), 5 (T 3), 10 (T 4) and 30 min (T 5) after tracheal tube extraction were recorded. The anxiety and depression scores of patients before the intervention and 1 d after the operation were compared between the two groups. The incidence of emergence agitation after the operation and complications during anesthesia awakening period were observed in the two groups, sino-nasal outcome test-20 (SNOT-20) was used to assess the postoperative recovery. Results:The incidence of emergence agitation in group G was lower than that in group D: 7.5%(3/40) vs. 25.0%(10/40), the difference was statistically significant ( χ2 = 4.50, P<0.05). There was no significant difference in systolic blood pressure, diastolic blood pressure and heart rate between the two groups at T 1 and T 5 ( P>0.05), but the level of above indicators in group G at T 2, T 3 and T 4 were significantly higher than those in group D ( P<0.05). The scores of State-Trait Anxiety Inventory(S-AI) and Self-Rating Depression Scale (SDS) in group G at the first day after the operation were significantly lower than those in group D: (35.45 ± 5.32) scores vs. (39.35 ± 4.91) scores, (35.42 ± 7.82) scores vs. (38.76 ± 5.21) scores, the differences were statistically significant ( P<0.05). The incidence of complications during anesthesia awakening period in group G was slightly lower than that in group D ( P>0.05). After the operation, the scores of sinusitis symptoms and nasal symptoms in the two groups were significantly decreased compared with those before the operation, and the scores of group G were significantly lower than those in group D ( P<0.05). Conclusions:Prospective intervention before anesthesia in patients with chronic sinusitis surgery can reduce stress response, improve bad mood, reduce the incidence of emergence agitation, and promote the postoperative recovery.
ABSTRACT
Objective To investigate the inhibitory effect of cordycepin on immune function injury in lung cancer rats after radiation therapy through JAK2/STAT3 signaling pathway. Methods Fifty rats were used to establish tumor-bearing model and other 10 rats were taken as normal group. After successful modeling, the rats were randomly divided into model group, radiotherapy group, cordycepin group, agonist group and agonist+cordycepin group (10 rats in each group). We compared tumor weight, tumor volume, tumor inhibition rate, IL-6, TNF-α, spleen index and thymus index, the number of T lymphocyte subsets, JAK2, p-JAK2, STAT3 and p-STAT3 protein expression levels among all groups. Results Compared with normal group, IL-6, TNF-α, CD8+, p-JAK2 and p-STAT3 in model group were increased, while spleen index, thymus index, CD4+ and CD4+/CD8+ were decreased (P < 0.05). Compared with model group, tumor weight, tumor volume, spleen index, thymus index, CD4+ and CD4+/CD8+ were decreased in radiotherapy group, while IL-6, TNF-α, CD8+, p-JAK2 and p-STAT3 were increased (P < 0.05). Compared with radiotherapy group, tumor weight, tumor volume, IL-6, TNF-α, CD8+, p-JAK2 and p-STAT3 were decreased in cordycepin group, while tumor inhibition rate, spleen index thymus index, CD4+ and CD4+/CD8+ were increased; tumor weight, tumor volume, IL-6, TNF-α, CD8+, p-JAK2 and p-STAT3 protein expression were increased in agonist group, while tumor inhibition rate, spleen index, thymus index, CD4+ and CD4+/CD8+ were decreased (P < 0.05). Compared with agonist+cordycepin group, tumor weight, tumor volume, IL-6, TNF-α, CD8+, p-JAK2 and p-STAT3 were decreased in cordycepin group, while tumor inhibition rate, spleen index, thymus index, CD4+ and CD4+/CD8+ were increased; tumor weight, tumor volume, IL-6, TNF-α, CD8+, p-JAK2 and p-STAT3 were increased in agonist group, while tumor inhibition rate, spleen index, thymus index, CD4+ and CD4+/CD8+ were decreased (P < 0.05). Conclusion Cordycepin can effectively inhibit the immune function injury in lung cancer rats after radiation therapy, and may play a regulatory role by inhibiting the JAK2/STAT3 signal pathway.
ABSTRACT
Objective To explore whether MiR-129-5p participates in radiosensitivity of medullary thyroid cell MZ-CRC-1 by inhibiting the gene expression of high mobility group protein B1 ( HMGB1) . Methods The radioresistant cell line MZ-CRC-1/R was established from MZ-CRC-1. Cell survival fraction was analyzed by colony formation assay. The expressions of miR-129-5p in MZ-CRC-1 and MZ-CRC-1/R cells were detected by qRT-PCR. Cell viability was determined by MTT assay. Cell apoptosis was measured by flow cytometry. Dual-luciferase reporter assay was performed to confirm the relationship between miR-129-5p and HMGB1. Besides, the protein expressions of HMGB1 and p-AKt were evaluated by western blot. Results Compared with that of MZ-CRC-1 cells, the survival fraction of MZ-CRC-1/R cells was significantly increased (t=3. 038, 4. 330, 4. 885, 4. 568, P<0. 05), the cell viability of MZ-CRC-1/R cells was also increased ( t=3. 637, 7. 734, 11. 896, 14. 522, P<0. 05) , and the expression of miR-129-5p(0.26±0.03) was significantly decreased in MZ-CRC-1/R cells(1.00±0.06) (t=19. 107, P<0. 05) . Compared with miR-NC-inhibitor group, cell viability was promoted and cell apoptosis was blocked in the miR-129-5p-inhibitor group ( t=5. 156, 6. 005, 9. 649, 8. 659, P<0. 05) . Moreover, miR-129-5p mimic suppressed cell viability and enhanced cell apoptosis after irradiation ( t=3. 118, 5. 034, 6. 005, 7. 488, 6. 362, P<0. 05) . Overexpression of miR-129-5p inhibited the protein expressions of HMGB1 and p-AKt (t=9. 325, 10. 614, P<0. 05). In addition, HMGB1 depletion rescued cell apoptosis that was reduced by miR-129-5p inhibitor in MZ-CRC-1 cells ( t=6. 700, P<0. 05) , while HMGB1 overexpression attenuated the effect of miR-129-5p upregulation on MZ-CRC-1/R cells ( t=7. 073,P<0. 05) . Conclusions miR-129-5p increased the radiosensitivity of medullary thyroid-like cell MZ-CRC-1 by inhibiting HMGB1.
ABSTRACT
Objective To explore the relationships of subjective well-being with personality trait and self-efficacy in policemen.Methods Totally 329 policemen from 3 prisons were assessed with General Well-Being Schedule (GWBS),Eysenck Personality Questionnaire (EPQ) and General Self-Efficacy Scale (GSES).The relationship between subjective well-being and personality traits,self-efficacy of policemen was analyzed using correlation analysis,variance analysis,regression analysis and structural equation modeling.Results The personality of extroverted stability had the highest score in GSE (2.74 ± 0.56) and GWB (88.89±11.90),while the introverted instability had the lowest(GSE:(2.19±0.46);GWB:(67.38±13.79)).Psychoticism(2.45± 1.72) was negatively correlated with GWB (78.24± 15.32) (r=-0.19,P＜0.01),neuroticism(5.07±3.31) was negatively correlated with GSE (2.50±0.57) and GWB (r=-0.38,-0.60,all P＜0.0l),while introversion-extroversion(8.13±2.86) was positively correlated with GSE and WGB (r=0.26,0.29,all P＜0.01).Structural equation model showed that neuroticism negatively influenced GWB (γ =-0.610,P＜0.01),and introversion-extroversion positively influenced GWB (γ=0.169,P＜0.05).Self-efficacy had partial mediating effect on relationship between neuroticism and GWB as well as the relationship between introversion-extroversion and GWB.Conclusions There is a high correlation between neuroticism and GWB.Self-efficacy plays a mediating role on relationship between personality trait and GWB.It can promote GWB of policemen by enhancing their self-efficacy.
ABSTRACT
Objective To explore the mediating effects of neuropeptide S receptor 1 and negative coping in chronic stress induced emotional responses. Methods A survey of 366 local residents who were chosen from County of Nandan in Guangxi Province by stratified random sampling method. Questionnaires of the life events scale (LES),the simplified symptom checklist and the Simplified Coping Style Questionnaire (SCSQ) were used. The level of NPSR1 was measured by Elisa. Data was analyzed by SPSS 21 and AMOS 21 statistical software for statistical analysis. Results The level of chronic psychological stress was (25. 24± 29. 26) and score of negative coping was(14. 84±4. 35). Somatic factor,anxiety factor,depressive factor and hostile factor were (1. 58±0. 58),(1. 43±0. 56),(1. 44±0. 55),(1. 23±0. 37). The total score of life e-vents was positively correlated with negative coping,somatic factor score,anxiety factor score,depression fac-tor score(r=0. 23-0. 46,P<0. 05),while negatively correlated with the expression level of detection of NPSR1 in plasma(r=-0. 26,P<0. 05). NPSR1 level was negatively correlated with body factor score,anxiety factor score,depression factor score and hostility factor score(r=-0. 18--0. 61,P<0. 05). Negative coping was positively correlated with body factor score,anxiety factor score,depression factor score and hostility fac-tor score(r=0. 12- 0. 27,P<0. 05). Both neuropeptide S receptor 1 and negative response had significant me- diating effects on emotional responses induced by chronic psychological stress (P<0. 05),and the effect val-ues were -0. 08 and 0. 05,respectively. According to the Bootstrapping method,the results of the mediation model showed that Bias-Corrected of 95% CI of the total standardization effect,the indirect standardization effect,the direct standardization effect were not including 0. Conclusion NPSR1 and negative coping plays a dual mediating effect on stress induced emotional responses.
ABSTRACT
Objective:To explore the relations among childhood trauma,autistic traits and dysexecutive functions in college students.Methods:Totally 2757 college students were assessed with the Childhood Trauma Questionnaire (CTQ).Sixty-three college students were randomly selected as the abused group according to the subscale cutoff point of CTQ Scale defined by Bernstein,and 93 students were randomly selected from students without history of childhood trauma as the control group.They were assessed with the Self-Rating Depression Scale (SDS),Autism Spectrum Quotient (AQ) and Dysexecutive Questionnaire (DEX) to measure depression,autistic traits and abnormality of executive functions,respectively.The individuals from the top and below 27％ of CTQ and AQ scores were defined as higher or lower-level different types of abused group and higher or lower-level autistic traits group,respectively.Results:The differences of DEX scores between higher or lower-level four types of CTQ (emotional abuse,physical abuse,sexual abuse,emotional neglect and physical neglect) and between higher or lower-level autistic traits group were significant (Ps ＜0.05).DEX scores in all higher-level groups were higher than all lower-level groups.Regression analysis showed that DEX score could be positively predicted by scores of emotional abuse,AQ and SDS (β =0.17-0.32,P ＜0.05).SDS score was a mediator between scores of emotional abuse and DEX,and between scores of autistic traits and DEX (95％ confidence interval were 0.05-0.32 and 0.07-0.55,respectively).Conclusion:Childhood trauma and autistic traits may positively predict dysexecutive function,and depression may play a mediating role between emotional abuse and dysexecutive function,and between autistic traits and dysexecutive function.

ABSTRACT
Objective To evaluate the efficacy of a type of endotracheal tube of extended with terminal swelling and resistance bending pressure for airway management during mechanical ventilation in children in prone position.Methods Sixty pediatric patients with cerebral palsy of both sexes,aged 3-7 yr,weighing 11-23 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective selective functional posterior rhizotomy,were randomly allocated into 2 groups (n =30 each) using a random number table:endotracheal tube of extended with terminal swelling and resistance bending pressure group (group E) and reinforced tracheal tube group (group C).After induction of anesthesia,the type of endotracheal tube of extended with terminal swelling and resistance bending pressure was inserted in group E,and the reinforced endotracheal tube was inserted in group C.The tidal volume,minute ventilation,dynamic lung compliance,arterial oxygen saturation and end-tidal pressure of carbon dioxide in pressurecontrolled ventilation mode were recorded in the two groups.Tube shedding caused by using of the extended tube was recorded during operation.Blood samples were collected from the femoral artery for blood gas analysis.Results Compared with group C,the tidal volume and minute ventilation were significantly increased (P＜0.05),and no significant change was found in dynamic lung compliance,arterial oxygen saturation and end-tidal pressure of carbon dioxide in group E (P＞0.05).Compared with the value before anesthesia,no significant change was found in pH value,arterial oxygen partial pressure and partial pressure of arterial carbon dioxide at the end of operation in the two groups (P＞0.05).In group C,the extended tube wasused in 3 patients,and among the 3 cases,one patient developed tube shedding which was treated immediately.Conclusion The type of endotracheal tube of extended with terminal swelling and resistance bending pressure provides better efficacy than the reinforced endotracheal tube when used for airway management during mechanical ventilation in children in prone position.
ABSTRACT
Objective A retrospective study was carried out for the analysis of correlation of traditional Chinese medical syndrome patterns of asthma patients at period of onset with five-element motions and six climatic factors. Methods All of the subjects were the inpatients of the First Affiliated Hospital of Guangzhou University of Chinese Medicine admitted from January 20, 2011 to January 19, 2014, matching the year of Xinmao, Renchen, Guisi correspondingly in ancient Chinese calendar. The patients were confirmed as asthma at period of onset and were differentiated into various traditional Chinese medical syndrome patterns. The time of onset was classified into various Yunqi periods according to the theory of five-element motions and six climatic factors, and then the correlation of syndrome patterns with the Yunqi periods was analyzed. Results A total of 308 inpatient case files were collected. In the year of Xinmao (2011) , 31 cases were differentiated as cold pattern asthma, 48 as heat pattern asthma, 6 as turbidity pattern asthma, 5 as wind pattern asthma. In the year of Renchen (2012) , 37 cases were differentiated as cold pattern asthma, 58 as heat pattern asthma, 13 as turbidity pattern asthma, 7 as wind pattern asthma. In the year of Guisi (2013) , 32 cases were differentiated as cold pattern asthma, 47 as heat pattern asthma, 14 as turbidity pattern asthma, 10 as wind pattern asthma. The results of statistical analysis showed that the differences of the distribution of syndrome patterns were insignificant among the year of Xinmao, Renchen, Guisi (P>0.05) . During the 3 years, heat pattern asthma had the highest incidence, cold pattern asthma came next, and turbidity pattern asthma and wind pattern asthma came last. Distribution of syndrome patterns of asthma in the year of Xinmao was consistent with the law of five-element motions and six climatic factors of the year of Xinmao. On the aspects of the theory of six Jianqi ( climatic periods) , the distribution of patterns of asthma in the climatic periods of Chuzhiqi, Erzhiqi, Sizhiqi was consistent with the law of climatic periods, while that in the climatic periods of Sanzhiqi, Wuzhiqi, Liuzhiqi was not consistent with the law of climatic periods. In the year of Renchen, syndrome pattern distribution was not consistent with the law of five-element motions and six climatic factors of the year of Renchen. In the climatic periods of Chuzhiqi, Erzhiqi, Sanzhiqi, the distribution of patterns of asthma was not consistent with the law of climatic periods, while that in the climatic periods of Sizhiqi, Wuzhiqi, Liuzhiqi was consistent with the law of climatic periods. In Guisi year, the distribution of syndrome pattern was not consistent with the law of five-element motions and six climatic factors of Guisi year either. On the aspects of the theory of six Jianqi, except for Erzhiqi, the distribution of patterns of asthma in the other five climatic periods was consistent with the law of climatic periods. Conclusion The theory of five-element motions and six climatic factors has some significance in predicting the pathogenic characteristics of asthma and in guiding the prevention and diag nosis of asthma, but convinced conclusion needs more proof from large-sample clinical trial.
ABSTRACT
Objective To evaluate the effect of cerebral palsy factor on the sensitivity of postopera?tive pain in the pediatric patients. Methods Twenty?five pediatric patients with cerebral palsy of both se?xes, of American Society of Anesthesiologists physical statusⅠorⅡ, aged 3-7 yr, weighing 11-25 kg, scheduled for elective lower abdominal or lower extremity surgery, served as cerebral palsy group ( group P). Another 25 pediatric patients without cerebral palsy of both sexes, of American Society of Anesthesiol?ogists physical status Ⅰ orⅡ, aged 3-7 yr, weighing 11-25 kg, served as control group ( group C) . At 2 h after surgery, pain was evaluated by using CRIES ( crying, requires O2 saturation, increased vital sign, expression and sleeplessness) . Peripheral venous blood samples were collected before surgery, and at 2 and 24 h after surgery, and the concentrations of plasmaβ?endorphin were measured by radio?immunity method, and the concentration of plasma catecholamine ( adrenaline) was determined by high performance liquid chromatography. Results Compared with the value before surgery, the plasma concentrations of β?endorphin were significantly decreased, and the concentrations of plasma catecholamine were increased after surgery in the two groups (P < 0?01). Compared with group C, the CRIES score was significantly in?creased after surgery, the concentration of plasmaβ?endorphin was decreased before and after surgery, and the concentration of plasma catecholamine was increased after surgery in group P ( P< 0?05 or 0?01) . Con?clusion The sensitivity of postoperative pain is increased in the pediatric patients with cerebral palsy.
ABSTRACT
Objective To evaluate the accuracy of nostril width method in intubation model choose in children with cerebral pal‐sy FSPR surgery .Methods Three hundred and fifty six cases of cerebral palsy FSPR surgery were selected ,the endotracheal intu‐bation were selected by nose width method and modified weight method ,and then we made a comparison between the two methods . Kappa consistency test and rank correlation analysis were both used to analyze the consistency .Results With Kappa=0 .81 ,rank correlation coefficient 0 .905 ,we could know that there was high degree of consistency between the two methods (P<0 .01) ,of which 298 cases (83 .7% ) children selected the same model intubation strengthen model in different method ,58 cases (16 .3% ) pe‐diatric intubation choice of two methods differ by one model .Conclusion Nostril width method was simple and reliable to select in‐tubation in pediatric surgery to strengthen FSPR model .
ABSTRACT
Objective To investigate the effect of dexmedetomidine on emergence agitation (EA) following sevoflurane anesthesia in children with cerebral palsy.Methods Fifty ASA physical status Ⅰ or Ⅱ children with cerebral palsy of both sexes,aged 2-12 yr,scheduled for elective muscle strength muscle tension adjustment method,were randomly allocated into 2 groups (n =25 each):control group (group C) and dexmedetomidine group (group D).Anesthesia was induced with iv injection of sufentanil 0.3 μg/kg,cisatracurium 0.15 mg/kg,and propofol 1.5 mg/kg.The patients were tracheal intubated and mechanically ventilated.Dexmedetomidine 0.5 μg/kg was intravenously infused over 15 min after induction of anesthesia in group D and the equal volume of normal saline was given in group C.The operation was begun at the end of administration.Anesthesia was maintained with inhalation of 2％-4％ sevoflurane and the concentration was adjusted to achieve a target BIS value of 45-60.The heart rate,systolic blood pressure and diastolic blood pressure were recorded before infusion of dexmedetomidine (T1) and at skin incision (T2).The extubation time,emergence time and consumption of sevoflurane were also recorded.The end-tidal sevoflurane concentration was recorded at T1,T2,and the end of operation (T3).The adverse cardiovascular events and occurrence of EA were also recorded.The degree of EA was assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale.The peripheral venous blood samples were collected at T1,T2,T3 and extubation (T4) for determination of the blood glucose level and serum cortisol concentration.Compared with group C,the emergence time and extubation time were significantly shortened,and the consumption of sevoflurane,end-tidal sevoflurane concentrations at T2 and T3,PAED scores,incidence of agitation,and the blood glucose level and serum cortisol concentration at T4 were significantly decreased in group D (P ＜0.05 or 0.01).There was no significant difference in the incidence of bradycardia or heart rate,systolic blood pressure and diastolic blood pressure at each time point between the two groups (P ＞ 0.05).Conclusion Dexmedetomidine can decrease the development and degree of EA following sevoflurane anesthesia in children with cerebral palsy.
