ABSTRACT
ObjectiveTo explore the clinical efficacy of Gouteng prescription in treating the patients with primary hypertension with anxiety disorder due to yang hyperactivity and heat toxin and the impact of the formula on the balance of inflammatory cytokines. MethodA total of 98 patients diagnosed with primary hypertension and anxiety disorder were randomized into control and observation groups. On the basis of conventional western medicine treatment for hypertension， the control group （47 patients） was treated with Shugan Jieyu capsules for 8 weeks， while the treatment group （51 patients） with Gouteng prescription for 8 weeks. The two groups were compared in terms of the blood pressure level， 24-hour blood pressure variability， Hamilton anxiety scale （HAMA） score， Pittsburgh sleep quality index （PSQI） score， quality of life （SF-36 scale） score， traditional Chinese medicine （TCM） syndrome score and efficacy， incidence of adverse reactions， and the levels of interleukin （IL）-1β， IL-6， IL-10， and IL-4 in the serum of peripheral blood. ResultThe final trial was completed with 95 patients， including 46 in the control group and 49 in the observation group. The treatment in both groups lowered the blood pressure and blood pressure variability （P<0.05， P<0.01）. The observation group outperformed the control group in recovering the systolic blood pressure （SBP）， 24-hour mean systolic blood pressure （24 h SBP）， 24-hour systolic blood pressure variability （24 h SBPV）， and 24-hour diastolic blood pressure variability （24 h DBPV） （P<0.05）. After treatment， the HAMA and PSQI scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower HAMA and PSQI scores than the control group （P<0.05）. Compared with those before treatment， the SF-36 scores in both groups increased （P<0.05， P<0.01）. After treatment， the observation group had higher scores of physiological function （PF）， bodily pain （BP）， social function （SF）， role-emotional （RE）， and mental health （MH） indicators than the control group （P<0.05）. After treatment， the TCM syndrome scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower score than the control group （P<0.05）. The total response rate regarding TCM syndrome in the observation group was 85.71% （42/49）， which was higher than that （63.04%， 29/46） in the control group （χ2=6.621， P<0.05）. The treatment in both groups lowered the levels of pro-inflammatory cytokines （IL-1β， IL-6） and elevated the levels of anti-inflammatory cytokines （IL-10， IL-4） （P<0.05， P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.05）. There were no adverse events during the research process. ConclusionGouteng prescription can recover the blood pressure level， reduce blood pressure variability， suppress anxiety state， improve sleep and quality of life， decrease TCM syndrome score， increase total response rate， lower serum IL-1β and IL-6 levels， and elevate serum IL-10 and IL-4 levels in the patients with primary hypertension complicated with anxiety disorder due to yang hyperactivity and heat toxin. It may exert the effects by regulating the balance of pro-inflammatory and anti-inflammatory cytokines.
ABSTRACT
Objective:To detect the potential biomarkers in the serum of adolescents with depressive disorder and provide the basis for clinical diagnosis of depression.Methods:A total of 45 adolescents with depression who met the inclusion criteria and 47 healthy controls (HC group) were screened.Patients with depression were treated with sertraline (100 mg/d) for 4 weeks.The patients before sertraline treatment were called DN-MDD group and then were called DT-MDD group after sertraline treatmant.Hamilton Depression Scale (HAMD) was used to evaluate the efficacy of the two groups before and after treatment.The serum was collected for UPLC-MS/MS to determine the changes in profiles of endogenous metabolites.And the software of SPSS 21.0, XCMS and Analyst 3.0 were used to analyze the data.The reliability and feasibility of clinical diagnosis were further analyzed by ROC via GraphPad 8.0.Results:After 4 weeks of sertraline treatment, the patients' HAMD score decreased (before: 19.71±1.72, after: 15.36±1.91) and the effective rate reached 51% ( P<0.01). Multivariate statistical analysis showed that HC group and DN-MDD group and DT-MDD group had significant differences in metabolic profile.Compared with healthy controls, 11 different metabolites were found in the plasma of DN-MDD group including glycerate, adenosine, creatine and so on.After treatment, concentrations of glucose, glutamate, aspartate, sucrose, creatine, pyruvate and adenosine were significant changes in serum of adolescent depression patients.Area under ROC curve of glucose and glutamic acid were >0.9, and the AUC of aspartic acid, sucrose, creatine, pyruvate and adenosine were >0.7, suggesting that these 7 metabolites had different degrees of diagnostic ability. Conclusion:There are different metabolic profiles between adolescents with or without depression, and the antidepressant sertraline is helpful to maintain the level of substance metabolism which can be used as one of the treatment methods for adolescent depression.Our research may support the new strategy for clinical diagnosis and treatment of adolescent depression.
ABSTRACT
Objective:To investigate the effects of prolonged exposure time on the behavior and hypothalamus-pituitary-thyriod(HPT) axis in post-traumatic stress rats.Methods:Fifty female rats and fifty male rats were respectively divided into 5 groups according to the random number table( n=10 in each group): blank group, D1F group(exposed in trauma environment for 2 min, sampled immediately after exposure), D1Y group(exposed in trauma environment for 90 min, sampled immediately after exposure), D4F group(exposed in trauma environment for 2 min, sampled after trauma environment fear memory test on the fourth day), D4Y group(exposed in trauma environment for 90 min, sampling after fear memory test of trauma environment on the fourth day). The anxiety and fear behaviors of rats were measured by capture rejection test, and the serum levels of thyrotropin-releasing hormone(TRH), thyrotropin(TSH), free triiodothyronine(FT 3), and free tetraiodothyronine(FT 4) were measured by enzyme-linked immunosorbent assay(Elisa). Results:(1)The rejection degree of male D4Y group and male D4F group were lower than that of blank group((1.70±1.77)points, (0.80±1.23)points, (3.60±1.43)points, P<0.05). There was no difference between female D4F group and blank group( P>0.05), and the rejection degree of female D4F group was lower than that of blank group((0.90±1.29)points, (3.30±1.57)points, P<0.05). (2)The levels of FT 3 and FT 4 in male D4F group were higher than those in blank group( P<0.05). Compared with male D4F group, the levels of FT 3 in male D1F group, D1Y group and D4F group were lower( P< 0.05). Compared with male D4F group, the levels of FT 4 in male D1F and D1Y group were lower((12.19±0.97)pmol/L, (11.19±0.21)pmol/L, (11.24±0.73)pmol/L, P<0.05). Compared with female blank group, female D1F group and female D4Y group, TRH level of female D1Y group decreased( P<0.05). Conclusion:Prolonging the exposure time in the trauma environment can reduce the stress activity of HPT axis in male rats, and the anxiety and fear behavior tend to be more obvious, while for female rats, although the anxiety and fear behavior tend to be normal, the HPT axis should not be activated after trauma.
ABSTRACT
Objective:To assess the association between the different prehospital transfer pathways to the hospital and reperfusion delay in patients with ST segment elevation myocardial infarction (STEMI).Methods:We retrospective collected 320 STEMI patients aged 18 years or older who underwent primary percutaneous coronary intervention (PPCI) from June 1, 2016 to July 31, 2018. They were divided into three groups according to different prehospital transfer pathways: patients directly transferred from the field by ambulance to PCI-capable center hospital (field transfer group, n=29); patients transferred by ambulance from PCI-incapable hospitals to PCI-capable center hospital (inerhospital transfer group, n=111); patients transferred by friends or relatives to PCI-capable center hospital (self-transfer group, n=180). The basic characteristic attributes, reperfusion time and fatal complications such as acute left heart failure cases (ALHF) cases, ventricular fibrillation (VF) cases, and in hospital death were collected and compared. In addition, logistic regression analysis was used to analyze uni- and multivariate of door-to-balloon (D2B) time less than 90 min. Results:The S2FMC interval were 118 min (50, 377) min , FMC-to-balloon interval were 87 min (66, 120.5) min and the onset-to-balloon time were 221 min (135, 482.5) min. The above three interval in the interhospital transfer group were longer than those in the field transfer and self-transfer groups ( P<0.05). S2FMC accounted for 51.14% of onset-to-balloon time in the field transfer group, 63.29% in the interhospital transfer group and 55.26% in the self transfer group. The door-to-catheter room interval were 33 min (9, 53.5) min. The interval in the interhospital transfer group were shorter than those in the field transfer and self-transfer groups ( P<0.05). The interval in the self-transfer group were longer than those in the interhospital transfer and field transfer groups ( P<0.05). Multiple regression analysis showed that the interhospital transfer group ( OR=15.251, 95% CI: 5.328-43.657, P<0.01), field transfer group ( OR=8.219, 95% CI: 1.861-36.307, P=0.005), FMC2ECG time ( OR=0.975, 95% CI: 0.962-0.989, P<0.01), and smoking ( OR=2.099, 95% CI: 1.015-4.341, P=0.045) were independent predictor of goal time less than 90 min ( P<0.05 for all variables). Adverse events in STEMI patients mainly occurred within 6 h of the initial symptoms. The incidence of VF was 3.75% (95% CI: 3.73%-3.77%), ALHF was 10.94% (95% CI: 7.52%-14.36%) and in-hospital mortality was 2.5% (95% CI: 0.79%-4.21%). There was no significant difference in the incidence of adverse events among the three groups ( P>0.05). Conclusions:The symptoms of STEMI patients are at risk in the early stage. Ambulances can shorten the reperfusion time, but the ambulance system is less used by patients. It is necessary to further optimize the treatment process of non-PCI hospitals and strengthen the popularity of emergency knowledge related to chest pain among residents, so as to shorten the reperfusion time.
ABSTRACT
Objective: To investigate the effects of domestic bivalirudin on plasma intercellular adhesion molecular-1 (ICAM-1) during percutaneous coronary intervention (PCI).Methods: Sixty PCI candidates were randomly divided into heparin group (n =30) and bivalirudin group (n =30).They were respectively treated with intravenous heparin and domestic bivalirudin as the anticoagulants during PCI.ICAM-1 in blood was measured before PCI and in 2h, 1d and 7d after PCI, respectively.Results: In heparin group, ICAM-1 level decreased significantly in 2 h after the intravenous injection when compared with that before the injection and that in bivalirudin group at the same time point (P＜0.05).No significant differences in ICAM-1 level were found on the 1st and 7th day after PCI in the two groups when compared with that before the administration (P＞0.05).Mild bleeding occurred in three patients receiving heparin and one patient receiving bivalirudin,but there was no significant difference after PCI.Conclusion: Compared with bivalivudin, heparin has a short inhibitory effect on the expression of ICAM-1 during PCI.It is beneficial to the patients with kidney disease or stroke during PCI.
ABSTRACT
OBJECTIVE:To investigate the effects of loading-dose rosuvastain before early percutaneous coronary intervention (PCI) on reperfusion arrhythmias in patients with acute non-ST-segment elevation myocardial infarction (NSTEMI).METHODS:A total of 136 patients with NSTEMI were randomly divided into loading-dose group (68 cases) and control group (68 cases).Both groups who were not given anti-platelet drugs were given loading-dose of Aspirin enteric-coated tablets 300 mg+Clopidogrel sulfate tablets 600 mg immediately after admission.The patients who were given aspirin regularly were given loading-dose of Clopidogrel sulfate tablets 600 mg only once after admission.The patients who were given clopidogrel regularly were given loading-dose of Aspirin enteric-coated tablets 300 mg only once.Those received PCI 12-24 h after medication.After PCI,they took Aspirin enteric-coated tablets 100 mg for life+Clopidogrel bisulfate tablets 75 mg at least 12 months.Loading-dose group was given loading-dose of Rosuvastatin calcium tablets 20 mg orally,12 h before surgery.All patients began to take Rosuvastatin calcium tablets 10 mg,once a day,since the night after the operation.Coronary angiography and the occurrence of reperfusion arrhythmia were observed in 2 groups.The levels of CK-MB and cTnT,major adverse cardiovascular events (MACE) were observed before and after surgery.RESULTS:There was no statistical significance in the number of diseased vessels,culprit vessels,the degree of culprit vessels stenosis or the incidence of MACE between 2 groups (P＞ 0.05).The incidence of reperfusion arrhythmia in loading-dose group was significantly lower than control group,with statistical significance (P＜0.01).There was no statistical significance in the degree of culprit vessels stenosis between 2 groups (P＞0.05).Before surgery,there was no statistical significance in the levels of CK-MB or cTnT between 2 groups (P＞0.05).After surgery,the levels of CK-MB and cTnT in 2 groups were significantly higher than before surgery,but the loading-dose group was significantly lower than the control group,with statistical significance (P＜0.01).CONCLUSIONS:Preoperative loading-dose of rosuvastatin before PCI can reduce the incidence of reperfusion arrhythmias in NSTEMI patients.
ABSTRACT
OBJECTIVE:To evaluate the effects of loading-dose rosuvastatin on vascular endothelial function in patients with non-ST segment elevation acute coronary syndromes (NSTE-ACS) after early interventional therapy. METHODS:Totally of 128 NSTE-ACS patients underwent early interventional therapy were randomly divided into conventional dose group (63 cases) and loading dose group(65 cases). Before operation,all patients were given Clopidogrel sulfate tablets 300 mg and Aspirin enteric-coat-ed tablets 100 mg;on this basis,conventional dose group was given Rosuvastatin calcium tablets 10 mg orally;loading dose group was given Rosuvastatin calcium tablets 20 mg orally. After PCI,both groups were given Rosuvastatin calcium tablets 10 mg orally, qd,and Aspirin enteric-coated tablets(100 mg/d)and Clopidogrel sulfate tablets(75 mg/d),for consecutive 3 months. The blood samples were collected before surgery,8 h and 24 h after surgery. The serum levels of CK-MB,cTn T,hs-CRP,ET and NO were detected. The occurrence of major adverse cardiovascular events was recorded within 3 months after surgery. RESULTS:Compared with before surgery,the serum levels of CK-MB,cTn T,hs-CRP and ET were increased significantly 8 h and 24 h after surgery, while the level of NO was decreased,with statistical significance (P0.05). CONCLUSIONS:For NSTE-ACS patients underwent ear-ly interventional therapy,loading dose of rosuvastatin can protect the patients and inhibit the injury of vascular endothelial cell in-duced by the surgery.

Prussian blue staining and fluorescence imaging studies showed that the RGD@BBN-lipo(QDs)-SPIO nanoparticles could target any αvβ3 or gastrin releasing peptide receptor overexpression breast cancer. Conclusions RGD@BBN-lipo(QDs)-SPIO is a novel long-circulating dual-receptor targeting and dual-modal molecular probe and has excellent physicochemical properties and stability, high T2 relaxivities and strong targeting effect on cancer cells and has laid a solid foundation for early diagnosis of breast cancer.
ABSTRACT
Objective To investigate the diagnostic value of the texture analysis derived from conventional MR imaging in differentiating glioblastomas from solitary brain metastases. Methods Thirty-four patients with pathological diagnoses of glioblastomas and 34 patients with pathological diagnoses of solitary brain metastases were enrolled in our study. All patients underwent conventional MR imaging including axial T1WI, T2WI, fluid attenuated inversion recovery (FLAIR) and contrast-enhanced T1WI before surgery. Texture features were calculated from manually drawn ROIs by using MaZda software. The feature selection methods included mutual information (MI), Fishers coefficient, classification error probability combined with average correlation coefficients (POE+ACC) and the combination of the above three methods. These methods were used to identify the most significant texture features in discriminating glioblastomas from metastases. Then the statistical methods including raw data analysis (RDA), principal component analysis (PCA), linear discriminant analysis (LDA) and nonlinear discriminant analysis (NDA) were used to distinguish glioblastomas from metastases. The results were shown by misclassification rate. Meanwhile, two senior radiologists (who had 5 and 9 years of experience in neuroimaging diagnosis, respectively) analysed the data of the 68 patients. Chi-square test was used to compare the differences in the results between the radiologists' analysis and the texture analysis. Results In the four kinds of sequences, the texture features for differentiating glioblastomas from solitary brain metastases were mainly from T2WI which had the lowest misclassification rate, 8.82% (6/68). The misclassification rates of the feature selection methods were similar in MI, Fisher's coefficient and POE + ACC (10.29%-27.94% for MI;11.76%-44.12% for Fisher's coefficientand 8.82%-38.24% for POE+ACC). However, the misclassification rate of the combination of the three methods (8.82%-33.83% for FPM) was lower than that of any other kind of method. In the statistical methods, NDA (8.82%-11.76% ) had lower misclassification rate than RDA (26.47%-39.71% ), PCA (27.94%-39.71%) and LDA (13.24%-44.12%). Misclassification rate of the radiologists' analysis 14.71%(10/68) was higher than that of the texture analysis, but there was no statistically difference between them (χ2= 10.993, P=0.287). Conclusion Texture analysis of conventional MR imaging can provide reliably objective basis for differentiating glioblastoma from solitary brain metastasis.

ABSTRACT
OBJECTIVE@#To evaluate signal intensity-time (SI-Time) curve and quantitative dynamic contrast-enhanced 3.0T magnetic resonance imaging in diagnosis and differentiating neoplasm of uterus. @*METHODS@#A total of 42 cases of uterine neoplasm (20 were malignant and 22 were benign) were evaluated in our study. All cases received dynamic contrast-enhanced scanning on 3.0T MRI. The raw data was processed by Siemens Tissue 4D software and the SI-Time curve was obtained and analyzed. Pharmacokinetic modeling of Tofts with a modeled vascular input function was used for calculating volume parameters: volume transfer constant (Ktrans), reverse volume transfer constant (Kep), the extravascular extracellular space volume per unit volume of tissue (Ve). The correlation of these parameters at each groups were investigated. The SI-Time curve and the data of perfusion parameters between the 2 groups were compared by T test. @*RESULTS@#Among 20 malignant tumors, 12 were cervical carcinoma and 8 were endometrial cancer. Among the benign tumors, 13 were leiomyomas, 3 were endometrial polyp, 3 were endometrial hyperplasia, and 3 were adenomyosis. 59.1% cases of benign tumors belong to Type I curve and 65% cases of malignant tumors belong to Type II curve. There was significant difference in SI-Time curve between benign and malignant tumors (P=0.011). If Type I curve was used as diagnostic criteria for benign tumors, and Type II and III curve were for malignant tumors, the diagnostic sensitivity, specificity, positive predictive value, negative predictive value were 90.0%, 59.1%, 66.7%, and 86.7%, respectively. Ve was 0.477 ± 0.143 in malignant and 0.614 ± 0.146 in control group with significant difference (P=0.004). Ve was 0.477 ± 0.143 in malignant and 0.589 0.176 in benign group with significant difference (P=0.004). Ktrans was (0.178 ± 0.067) min⁻¹ in malignant and (0.263 ± 0.111) min⁻¹ in control group with significant difference (P=0.003). Ktrans was (0.182 ± 0.096) min⁻¹ in benign and (0.263 ± 0.111) min⁻¹ in control group with significant difference (P=0.011). @*CONCLUSION@#The type of SI-Time curve and perfusion parameters were important for differentiating benign and malignant uterine tumors in dynamic enhanced MRI.

ABSTRACT
Objective Toinvestigatetheimpactofthedifferentrupturepoints(sac,neck,andtop) of intraoperative aneurysm rupture (IAR)on the prognosis of patients in anterior circulation aneurysm clipping.Methods Theclinicaldataof135consecutivepatients(148aneurysms)acceptedmicrosurgical aneurysm clipping from May 2009 to March 2012 were analyzed retrospectively. The prognostic evaluation of the patients after procedure was assessed by using the Glasgow outcome scale (GOS). The different aneurysm rupture points of IAR were used as influencing factors,and the relationship between the different rupture pointsandtheprognosisofpatientswasanalyzed.Results Duringclippingof148aneurysmsin 135 patients,31 aneurysms in 30 patients had intraoperative rupture (20. 9% of the aneurysms, 22.2% of the patients). Nine rupture points occurred on the top of aneurysms,17 occurred on the sac,and 5 occurred on neck. The Glasgow outcome scale (GOS)scores 5,4,3,2 and 1 were in 17,8,2,1 and 2 patients,respectively. A total of 25 patients had good prognosis and 5 cases had poor prognosis. There were no significant differences in the impact of different rupture points of IAR on the prognosis in patients of IAR (OR,100. 00,95% confidence interval 6. 764-18. 344,P=0. 006). Of the 25 patients with aneurysm sac or top rupture,1 case had poor prognosis. Of the 5 patients with aneurysm neck rupture, 4caseshadpoorprognosis.Conclusion Inanteriorcirculationaneurysmclipping,thedifferent aneurysm rupture points may have significant impact on the prognosis of patients,the aneurysm neck rupture is a main factor for resulting in the poor prognosis of patients.
ABSTRACT
Objective To build a supervision mechanism for independent clinical labs (ICL),surveyed the current situation of such novel institutions in China.Methods By way of the nationwide network of clinical labs,ICL in China were surveyed by written questionnaires and spot inspection.Results In the surveyed 38 ICLs,the maximum registered capital was 44 900 thousands,the minimum was 2 000 thousands.The maximum number of employee was 1 105,the minimum was 19.6 labs passed ISO15189 ratification,4 labs passed CAP ratification.17 labs participated in local external quality control,29 labs par-ticipated in national external quality control.Conclusion Although ICL in our country have developed well in the past dec-ade,such vulnerabilities as unbalanced staff ratio,full-range quality control bugs,cutthroat competition,asymmetrical infor-mation disclosure and bio-safety have loomed in the meantime.It is time to formulate a stricter industry access system and appropriate regulatory modes.
ABSTRACT
Aim To investigate the preventive effect of Guizhi decoction on cardiac sympathetic sprouting induced by 4-Methylcatechol (4-MC) . Methods The rat models of cardiac sympathetic sprouting were in-duced by 10 mg · L-1 4-MC ( 10μg · kg-1 body weight, i. p. ) . Guizhi decoctions ( with different pro-portion between Ramulus Cinnamomi and Radix Paeon-iae Alba, 1 : 1, 1 : 2 and 2 : 1) and metoprolol were administered to the rats. Heart rate and electrocardio-gram ( ECG ) were observed, the content of norepi-nephrine (NE), growth associated protein (GAP-43), tyrosine hydroxylase ( TH ) and acetylcholine transfer-ase enzyme ( CHAT) in myocardial homogenate of left ventricular and right atrial were determined by ELISA method, and immunofluorescence assay was used to observe cardiac nerve sprouting and sympathetic distri-bution. Results 4-MC caused cardiac sympathetic sprouting and parasympathetic was not influenced. Heart rate of the model group was improved significant-ly and higher than that of the other groups . Compared with the model group, the content of NE, GAP-43 and TH in left ventricle and right atrium of the metoprolol group and Guizhi decoction group were decreased( P<0.05 ) , and the immunofluorescence result showed that the distribution of TH positive nerve was reduced sig-nificantly(P<0.05). It was demonstrated that Guizhi decoction of the proportion between Ramulus Cinnamo-mi and Radix Paeoniae Alba 1 : 1 and 1 : 2 had the best efficacy, which was similar to the efficacy of meto-prolol. Conclusion Guizhi decoction ( with the pro-portion between Ramulus Cinnamomi and Radix Paeon-iae Alba 1 : 1 and 1 : 2 ) effectively inhibits the cardi-ac sympathetic sprouting induced by 4-MC.
ABSTRACT
ObjectiveTo study the relationship of the parental rearing behaviors between the psychological status and post-traumatic stress disorder in the injured deliberately.Methods 161 injured people were treated in five hospitals of the Urumqi and evaluated the self-reporting questionnaire-20 (SRQ20),7-items screening scale for PTSD( PTSD7 ),impact of event scale (IES) and symptom checklist 90 (SCL-90) in the third and the fourth week injured,including 113 injured people aged at 14 ～50 years old completed the Egna Minnen av Barndoms Uppfostran (EMBU).Two months after the injury,113 injured people were interviewed,including 106 injured people diagnosed by Structured Clinical Interview for DSM-Ⅳ-TR Axis Ⅰ Disorders/Patients (SCID-I/P) and 7 injured people were lost.ResultsFather's preferences correlated with the total score of IES ( r =- 0.234,P ＜ 0.05 ) and avoid factor( r=-0.309,P＜ 0.01 ) positively,Mother's emotional warmth and understand correlated with the flashback factor of IES ( r =0.194,P ＜ 0.05 ) negatively.The injured people were divided into three groups by diagnosis:the illness-free group,the PTSD group,and other group.Parental preferences correlated with Mental symptoms negatively.Father's punish severely,interference too much,refuse or deny and Mother's interference too much,over protection and punish severely correlated mental symptoms positively.The six subscales of father's rearing behaviors and the five subscales of mother's rearing behaviors had no significant difference.ConclusionsParental preferences in childhood can internalizes inside support to protect the psychological trauma in future.Father's punish severely,interference too much,refuse or deny and mother's interference too much,over protection and punish severely can damage mental health and aggravate symptoms after traumatic event.But the influence of parental rearing behaviors is limited to decide whether the injured people suffering from PTSD or other mental disorders.
ABSTRACT
Objective: To explore the stress effects of traffic accident on changing the NO level and SOD activity, as well as the relationship between personality and prognostic change. Methods: Serum level of NO and activity of SOD were measured in 152 patients with traffic accidents and in 60 control subjects. All subjects were assessed with the Eysenck Personality Questionnaire (EPQ). Results: NO and SOD were significantly higher in patients as compared to controls ( P
