Objective: To explore the relationship between cyberbullying and depression in college students, and to provide a scientific basis for the prevention of cyberbullying. Methods: A total of 3 914 college students from 6 universities in Shanxi Province were selected as research objects. The students’ cyberbullying behavior scale and depression self-rating scale were used to investigate the students. Results: The overall reported rate of cyberbullying among college students was 17.4%. Boys who suffered from online verbal bullying and online fraud scored higher than girls. Students whose parents divorced scored higher than those whose parents did not divorce in all dimensions of cyber-bullying. There was a statistically significant difference in the overall scores of students with different degrees of education and time spent online( P <0.05). Depression was reported in 15.6% of participants. The depression scores of female students were higher than that of male students.College students whose parents were divorced had higher depression scores than those whose parents were not divorced.There were statistically significant differences in depression scores among college students with different fathers’ education levels and different time spent online every day( t / F =2.05, 6.64, 3.91 , 19.52, P <0.05). Pearson correlation analysis showed that online speech bullying, online fraud and identity concealment bullying were positively correlated with depression scores( r s =0.40, 0.36, 0.46, P <0.01). Multiple linear regression analysis showed that three forms of cyberbullying were risk factors for the increase of depression in college students( β =0.89, 0.38, 0.38, P <0.01). Conclusion Cyber-bullying is one of the risk factors for increasing the severity of depression among college students.Strengthening the management of Internet use, promotion college students’ interpersonal conununication and active cooperating between society, school and family are great significance to reduce the occurrence of cyberbullying.

Objective: To explore the relationship between childhood maltreatment and suicide ideation of college students,so as to provide basis for physical and mental health of college students. Methods: Students from 6 universities in Shanxi Province(3 854 college students provided eligible questionniare for childhood abuse and 3 882 for suicidal ideation) were selected by multi-stage random cluster sampling from May to July 2018, the Chinese Version of the Childhood Trauma Questionnaire and the Self-rating Idea of Suicide Scale were used in the survey. Results: Of all subjects,42.4% had at least one kind of abuse experience in childhood and 3.9% had suicidal ideation in the past week. By chi square test,the detection rate of suicidal ideation of college students who suffered physical abuse,emotional abuse,sexual abuse,physical neglect,emotional neglect in childhood was higher than that of college students without maltreatment (χ2=13.78，12.97，17.10，56.56，66.58，P<0.01)；Spearman correlation analysis showed that there was a positive correlation between each type of maltreatment in childhood and college students’ suicidal ideation(r=0.06，0.06，0.07，0.12，0.13，P<0.01)；Multivariate Logistic regression model found that after controlling other influencing factors,physical neglect and emotional neglect in childhood were independent risk factors for suicide ideation of college students (OR=2.18,2.07,P<0.05). Conclusion Physical neglect and emotional neglect in childhood can increase the risk of college students’ suicidal ideation. Paying enough attention and care to them in early childhood may help to prevent their suicidal ideation in adulthood.

Objective: To explore the relationship between childhood abuse and cyberbullying among college students and to provide theoretical support for early intervention of cyberbullying among college students. Methods: A total of 3 850 sophomores and juniors from 6 universities in Shanxi Province, randomly selected by stratified cluster sampling method, were investigated by using the Questionnaire on Cyberbullying and the Chinese Version of the Child Abuse Questionnaire. Results: Male students reported higher rates of sexual abuse, emotional neglect and physical neglect than female students(χ2=5.22, 4.39, 7.53 P<0.05). The child abuse report rate of college students whose parents divorced was higher than that of those whose parents were not divorced(χ2=86.80, 134.06, 130.18, 175.64, 118.46，P<0.05). In addition to physical neglect, childhood abuse rate of only children was higher than that of non-only children, with statistically significant differences(χ2=9.44, 12.44, 21.18, 21.26, all P<0.05). The scores of all factors and total scores of cyberbullying implemented by male students were higher than those by female students(t=9.35, 5.59, 5.83, 7.57，P<0.05); the scores of all factors and total scores of cyberbullying implemented by only-child students were higher than those by non-only-child students(t=2.79, 3.74, 4.78, 4.40，P<0.05); the scores of all factors and total scores of cyberbullying implemented by students whose parents were divorced were higher than those by students whose parents were not divorced, with statistically significant differences(t=6.99,6.78, 8.04，11.33, P<0.05). Multiple linear regression model showed that there was a positive correlation between the childhood abuse of college students and the implementation of cyberbullying, and regression coefficient differences of all factors were statistically significant(β=0.10, 0.11, 0.05, 10.08,0.06, P<0.05). Conclusion Childhood abuse experiences increase the risk of college students practicing cyberbullying.

Objective:To detect the abnormal changes of myocardial blood perfusion in patients with hypertrophic cardiomyopathy (HCM) by myocardial contrast echocardiography(MCE) combined with exercise stress test.Methods:Twenty-seven patients with clinically diagnozed of asymmetric HCM in Fuwai Central China Cardiovascular Hospital from May 2020 to April 2021 were selected as the HCM group, and 29 healthy subjects during the same period were selected as the control group. All patients underwent routine echocardiography, resting and exercise stress MCE. The myocardial perfusion parameters of each segment of interventricular septum in the 2 groups were quantitatively analyzed: the peak plateau intensity (A value), ascending slope of the curve(β value) and value of A×β. According to the end-diastolic myocardial thickness, the interventricular septum of the HCM group was divided into hypertrophic and non-hypertrophic segments, and the myocardial contrast parameters of the interventricular septum of the study group were compared with those of the control group. The myocardial blood flow reserve value of the two groups were calculated, and the correlation of myocardial blood flow reserve value with left ventricular mass index (LVMI) and left ventricular remodeling index (LVRI) were analyzed.Results:No matter at rest or under stress, the A value, β value and A×β value of ventricular septal hypertrophic and non-hypertrophic segments in the hypertrophic cardiomyopathy group were lower than those in the control group, and the differences were statistically significant (all P<0.05). Under stress, the A value, β value and A×β value of interventricular septal hypertrophic segments were lower than those in non-hypertrophic segments in the HCM group, and the differences were statistically significant (all P<0.05). The myocardial blood flow reserve in the HCM group was negatively correlated with LVMI and LVRI( r=-0.899, -0.676; all P<0.001). Conclusions:In patients with HCM under resting and exercise stress, microcirculation disorders were found in both hypertrophic and non-hypertrophic segments of the ventricular wall, and the myocardial blood flow reserve was negatively correlated with LVMI and LVRI.

Objective:To explore the clinical value of adenosine stress myocardial contrast echocardiography in detecting myocardial blood perfusion abnormalities in patients with type 2 diabetes mellitus.Methods:Twenty-six patients with type 2 diabetes mellitus clinically diagnosed from May 2019 to January 2020 in the endocrinology department of Fuwai Central China Cardiovascular Hospital and 28 healthy examinees with gender and age matched during the same period were enrolled. Routine echocardiography, rest and adenosine stress myocardial contrast echocardiography were performed, the plateau signal intensity(A value), curve rising slope(K value) and A×K value of the myocardial perfusion time-intensity curve were obtained by offline analysis. And general data such as age, gender, disease course, body mass index and glycated hemoglobin were collected, and results of the two groups were compared statistically.Results:In the rest state, the A value of the myocardial perfusion parameter in the diabetic group was not significantly different from that of the control group, both in whole and in segments ( P>0.05), while the K value and A×K value of the myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group ( P<0.05). In the stress state, the A value, K value and A×K value of myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group, both in whole and in segments ( P<0.05). The detection rate of myocardial perfusion abnormality in the stress state was significantly higher than that in the rest state, and the difference was statistically significant ( P<0.05). The myocardial blood flow reserve in the diabetic group was negatively correlated with the course of disease and the level of glycated hemoglobin ( r=-0.580, P=0.020; r=-0.481, P=0.013). Conclusions:Adenosine stress myocardial contrast echocardiography can be used for detection of left ventricular myocardial perfusion abnormalities in patients with type 2 diabetes mellitus, which has great clinical application value.

Objective:To investigate the change and clinical significance of serum alkaline phosphatase (ALP) level in patients with acute spontaneous intracerebral hemorrhage(AICH).Methods:81 patients with AICH admitted to the Neurosurgery Department of Tianjin Third Central Hospital from January 2019 to October 2020 were retrospectively analyzed. 81 patients with non cerebral hemorrhage who came from the health examination center or complained of dizziness and had no hepatobiliary and skeletal diseases were selected as the control group. The clinical data of all the patients were recorded, including gender, age, Glasgow Coma Scale (GCS) score, hemorrhage location, liver function indexes, the history of hypertension, diabetes, heart disease, smoking, drinking, and so on. The differences in clinical data between the two groups were compared. Pearson correlation was used to analyze the correlation between liver function indexes and GCS score. The independent risk factors for AICH were screened by binary logistic regression, and the receiver operating characteristic (ROC) curve was used to evaluate the value of serum ALP in predicting intracerebral hemorrhage.Results:Serum ALP level in AICH group was significantly higher than that in the control group [85.0(70.0, 103.0) U/L vs 65.0(54.5, 71.5)U/L, Z=6.740, P<0.001]. Pearson correlation analysis showed that serum ALP had a negative correlation with GCS score ( r=0.255, P=0.022). Binary logistic regression analysis showed that hypertension ( OR=20.440, 95% CI 8.572-48.737) and ALP ( OR=1.077, 95% CI 1.049-1.105) were risk factors for intracerebral hemorrhage. Serum ALP level was an independent risk factor ( OR=1.069, 95% CI 1.038-1.101) for AICH after adjusting for confounding variables including age, AST, history of hypertension. ROC curve showed that the area under the curve (AUC) of serum ALP in predicting intracerebral hemorrhage was 0.807 (95% CI 0.740-0.873, P<0.001), with sensitivity of 67.9% and specificity of 81.5%. Conclusions:Serum ALP level may be related to the occurrence and severity of AICH. Therefore, serum ALP level can be used as a reference index to evaluate the occurrence, severity of patients with AICH.

Objective:To detect the abnormal changes of myocardial blood perfusion in patients with hypertrophic cardiomyopathy(HCM) by myocardial contrast echocardiography (MCE) combined with adenosine stress test.Methods:Fifteen adult patients with HCM who were treated in Fuwai Central China Cardiovascular Hospital from May 2021 to March 2022 were prospectively selected as the HCM group, and eighteen healthy volunteers matched by gender, age and body surface area during the same period were chosen as the control group. All subjects underwent routine echocardiography, rest and adenosine stress MCE. The MCE images were analyzed by QLab software to obtain the myocardial perfusion parameters: peak signal intensity (A value), rising slope of the curve (β value) and A×β value, and the differences of above parameters between the two groups were compared.According to whether the end-diastolic wall thickness ≥12 mm, the myocardial segments in the HCM group were divided into hypertrophic segments and non-hypertrophic segments. The differences in myocardial perfusion parameters were compared among control group segments, hypertrophic segments and non-hypertrophic segments of the HCM group. The correlations of stress myocardial blood flow with maximal left ventricular wall thickness (MLVWT), left ventricular mass index (LVMI) and left atrial volume index (LAVI) in the HCM group were analyzed.Results:Compared with the control group, the A value, β value and A×β value of whole myocardium, hypertrophic segments and non-hypertrophic segments in the HCM group were significantly decreased in the rest and adenosine stress state, and the differences were statistically significant (all P<0.05). In the stress state, the A value, β value and A×β value of the hypertrophic segments were significantly lower than those in the non-hypertrophic segments in the HCM group, and the detection rate of abnormal perfusion segments in the HCM group was significantly higher than that in the rest state(all P<0.05). Compared with the control group, the myocardial blood flow reserve of whole myocardium, hypertrophic segments and non-hypertrophic segments in the HCM group were significantly decreased, and the differences were statistically significant(all P<0.05). The stress myocardial blood flow in the HCM group was negatively correlated with MLVWT, LVMI and LAVI ( r=-0.815, -0.805, -0.742; all P<0.05). Conclusions:Myocardial blood perfusion abnormalities can occur in both hypertrophic and non-hypertrophic myocardial segments in patients with HCM, and adenosine stress MCE can significantly improve the sensitivity of detecting myocardial perfusion abnormalities. The stress myocardial blood flow in patients with HCM is negatively correlated with MLVWT, LVMI and LAVI.

To investigate the value of injecting a small amount of absolute ethanol into the benign solid nodules of the thyroid before radiofrequency ablation(RFA)to improve the efficiency of radiofrequency ablation. A total of 98 eligible patients(98 nodules)with pathologically confirmed benign solid nodules who were treated in our center from December 2016 to February 2018 were included and randomized into ethanol ablation(EA)combined with radiofrequency ablation(RFA)group(EA+RFA group)and RFA group,with 49 patients in each group.Routine ultrasound,contrast-enhanced ultrasound(CEUS),and thyroid function test were performed before treatment and 1,3,6,and 12 months after treatment.The general information,treatment time,ablation energy,ablation power,postoperative nodule volume reduction ratio(VRR),symptom score(SS)and cosmetic score(CS),thyroid function level,and incidence of complications were compared between these two groups. The mean treatment time [(441.30±243.31)s (790.70±349.82)s;= 4.403, =0.000],mean ablation energy [(3.92±2.01)kJ (5.15±2.12)kJ;=2.709, =0.009],and mean ablation power [(6.07±1.44)W (7.30±1.29)W;=3.612, =0.006] were significantly lower in the EA+RFA group than in the RFA group.At 3,6 and 12 months after surgery,the VRR in the EA+RFA group was(57.73±11.07)%(=-3.16, <0.001),(64.40±10.56)%(=-5.45, <0.001),and(77.29±8.48)%(=-10.46, <0.001),respectively;the VRR in the RFA group was(55.44±13.01)%(=-1.76, <0.001),(65.28±11.33)%(=-5.09, <0.001),and(75.17±9.84)%(=-8.93, <0.001),which were significantly smaller than those before surgery.There was no significant difference in VRR between the EA+RFA group and the RFA group at 1(=3.41, =0.33),3(=2.05, =0.21),6(=2.77, =0.49),and 12 months(=5.05, =0.10)after treatment.During the follow-up,no recurrence of nodules was observed on CEUS.In the EA+RFA group,the SS [(1.77±0.86).(5.54±2.15);=9.63, <0.001] and the CS[(1.39±0.77).(3.32±0.61);=10.09, =0.004]at 12 months after surgery were significantly lower than those before surgery.In the RFA group,SS [(1.63±1.04).(5.90±1.79);=12.72, <0.001] and CS [(1.64±0.83).(3.15±0.72);=8.13, =0.012] at 12 months after surgery were also significantly lower than those before surgery.The CSS in the EA+RFA group was significantly lower than that in the RFA group [(0.93±0.55).(2.44±0.53);=-11.70, =0.007].Both groups had no significant change in thyroid function during the follow-up period,and no serious complications were observed. Anhydrous alcohol injection can effectively improve the efficiency of radiofrequency ablation in treating benign solid thyroid nodules and is effective in reducing nodule volume,alleviating compressive symptoms,and decreasing cosmetic discomfort.
