Objective To explore the influence of individualized health education to asthma children on the quality of life of their parents.Methods One hundred and one parents of asthmatic children from 3 different communities were randomly assigned to the intervention group(n=52)and the control group(n=49).Follow-ups were performed by phone calls and the Children Asthma Health Education Brochures were distributed among them in the two groups,meanwhile the individualized health education was given to the intervention group.The paediatric asthma caregiver's quality of life questionnaire(PACQLQ)was used to assess the quality of life of two groups.Results One month after intervention,the scores of the intervention group on PACQLQ total score as well as its items of activity limitation and emotional function were significantly higher than the control group(P<0.001 for all).Conclusion The individualized health education to the asthmatic children can improve the quality of life of their parents.

This study aimed to evaluate the feasibility and effectiveness of closing the small bowel in an ex vivo porcine model with high-frequency welding device. A total of 100 porcine small bowels were divided into two groups, and then were closed with two different methods. The fifty small bowels in experimental group were closed by the high-frequency welding device, and the other fifty small bowels in comparison group were hand-sutured. All the small bowels were subjected to leak pressure testing later on. The speed of closure and bursting pressure were compared. The 50 porcine small bowels closed by the high-frequency welding device showed a success rate of 100%. Compared with the hand-sutured group, the bursting pressures of the former were significantly lower (P<0.01) and the closing process was significantly shorter (P<0.01). The pathological changes of the closed ends mainly presented as acute thermal and pressure induced injury. Experimental results show that the high-frequency welding device has higher feasibility in closing the small bowel.

Objectiye To observe the prevalence of prolonged seizures and the changes of biochemical markers of myocardial injury in patients with prolonged seizures after modified electroconvulsive therapy(MECT).Methods Patients treated with MECT or simulated ECT were divided into three groups.Group Ⅰ , 26 patients,experienced at least one prolonged seizure after MECT;group Ⅱ,41 selected patients, had not prolonged seizures at all during a course of MECT treatments and group Ⅲ, 31 patients, received simulated ECT.Biochemical markers of myocardial injury, including phosphocreatine kinase (CK), MR isoenzyme of phosphocreatine kinase (CK-MB), lactate dehydrogenase ( LDH ), α-hydroxybutyrate dehydrogenase ( α-HBDH ) and cardiac troponin (cTnT) ,were measured immediately, 3 hours later and on the following day after the first prolonged seizure for group Ⅰ ,the same time points as group Ⅰ after the first treatment of MECT for group Ⅱ , immediately after simulated ECT for group Ⅲ.These indexes were compared between the patients of three groups.Results The positive rate ofcTnT was 30.8%(8/26) and 17.1% (7/41)in group Ⅰ and Ⅱ respectively, but no difference was found(P＞0.05 ).CK measured immediately after MECT in patients of group Ⅰ was significantly higher than that of group Ⅲ(P ＜ 0.05 ).CK-MB (immediately), LDH ( immediately and 3 hours later) and α-HBDH ( immediately, 3 hours later and on the following day) in patients of group Ⅰ were significantly higher than those of group Ⅱ and Ⅲ measured after MECT or simulated ECT(P＜0.05 ).Conclusion More attention should be paid that absolute or relative hypoxemia may lead to minor myocardial injury.

Objective To explore the predictive effect of depression and impulsivity on suicidal ideation in violent criminals.methods 423 violent criminals were assessed by Self-rating Idea of Suicide Scale(SIOSS),Patient Health Questionnaire (PHQ-9) and Barratt Impulsiveness Scale(BIS-11).Result sPeople with suicidal ideation accounted for 17.04% of the total number of violent criminals.The scores of the group with suicidal ideation (respectively (4.95±4.82),(56.79±8.68),(12.95±2.29),(19.03±3.91),(28.81±4.95)) were higher than those without suicidal ideation group (respectively (4.95±4.82),(56.79±8.68),(12.95±2.29),(19.03±3.91),(28.81±4.95)) in depression and every dimension of impulsivity(attentional impulsivity,motor impulsivity and non-planning impulsivity) (t=9.49,t=4.61,t=4.04,t=3.88,t=3.08) (all P<0.01).Positive correlation was observed between suicidal ideation,depression and impulsivity(r=0.156-0.628,P<0.01),while sleeping factor was not associated with non-planning impulsivity.According to the multi-factoral regression module,depression and nonplanning impulsivity scores had positive prediction on suicidal ideation(R2=0.419,SIOSS=-2.471+ 0.192× depression+ 0.149× nonplanning impulsivity).Conclusion There is a close relationship in suicidal ideation,depression and impulsivity,meanwhile depression and nonplanning impulsivity can predict the suicidal ideation.

Objective To investigate the feasibility of the adaptive cardio sequence prospective ECG-gated dual-source CT coronary angiography (CTCA).Methods Thirty one patients underwent prospective ECG-gated dual-source CTCA. The patients were divided into two groups: group A, heart rate ≤ 75 times / minutes, 70% of R-R interval was chose; group B, heart rate> 75 times / minutes, 40% of R-R interval was chose. Two experienced radiologists assessed the image quality of 15 segments of coronary arteries in a double blinded fashion in a four score scale. Student t test was used to compare the image quality between two groups. CT dose index(CTDIvol) and effective dose(ED) were also calculated for both groups. Results 437 segments of coronary arteries in 31 patients were included this analysis, 408 segments (93.4%) had assessable image quality, while 29 segments (6.6%) had non assessable image quality. Of 226 segments in group A, 12 segments (5.3%) had non assessable image quality; however, 17 segments (8.1%) of 211 segments in group B had non assessable image quality. The average score of image quality was 3.57±0.64 in 31 patients. There was no statistical difference for mean image quality of group A (3.65±0.39) and group B (3.41±0.43)( t=1.62,P=0.12 ) . There was a statistical difference for mean image quality for segment 10 on a per segment basis ( t = 3.8 ,P＜0.05). CTDIvol and ED were (18.88±5.04) mGy and (4.31±1.05) mSv, respectively.Conclusion Adaptive cardio sequence prospective ECG-gated dual source CT can acquire assessable image quality of coronary artery with lower radiation dose to the patients, which has the potential to be a routine CTCA technique.

PURPOSE: Recent evidence suggests that B cells can both promote and inhibit the development and progression of allergic disease. However, the characteristics of B cell subsets in patients with allergic rhinitis (AR) have not been well documented. This study aimed to analyze the characteristics of B cell subsets in the peripheral blood of AR patients. METHODS: Forty-seven AR patients and 54 healthy controls were enrolled in this study, and the B cell subsets in peripheral blood of all subjects were analyzed by flow cytometry. Moreover, the serum total immunoglobulin E (IgE) and IgE concentrations secreted into the cultured peripheral blood mononuclear cells (PBMCs) were measured by using enzyme-linked immunosorbent assay. RESULTS: We found the peripheral blood of AR patients contained higher percentages of memory B cells, plasma cells, and CD19+CD24hiCD27+ regulatory B cells (Bregs) than those of age-matched healthy controls (P < 0.05), while the percentages of naïve B cells and CD19+CD24hiCD38hi Bregs were significantly lower in AR patients than in healthy individuals (P < 0.05). In addition, the serum total IgE and IgE concentrations secreted into the cultured PBMCs were elevated in AR patients than in the healthy controls (P < 0.05). CONCLUSIONS: Our findings indicate that AR patients were characterized by increase in terminally differentiated memory B cells or plasma cells and decreases in CD19+CD24hiCD38hi Breg cells in the peripheral blood.

AIM: To compare the efficacy of different dosing regimens of conbercept in the treatment of pathological myopic choroidal neovascularization(CNV).METHODS: Prospective clinical study. Totally 42 patients(42 eyes)who were diagnosed with pathological myopic CNV in our hospital from January 2019 to January 2022 were selected in the study. According to two different initial dosing regimens, the patients were divided into 1+pro re nata(PRN)group, with 20 patients(20 eyes), and 3+PRN group with 22 patients(22 eyes). The patients in the 1+PRN group were given one intravitreal injection and then given PRN, the patients in the 3+PRN group were given intravitreal injection once a month for 3 mo and then given PRN. Followed-up for 12 mo after initial treatment, the best corrected visual acuity(BCVA), central macular thickness(CMT), CNV area and injection times were compared between the two groups.RESULTS: The BCVA was improved, CMT was decreased, and CNV area was reduced at 1, 3, 6, and 12 mo after the initial treatment(P<0.01). However, there was no statistically significant difference in BCVA, CMT and CNV area between two groups(P>0.05). The average injection in the 1+PRN group was significantly less than that of the 3+PRN group [2(1, 3)times vs 3(3, 4)times, P<0.05], but the average reinjection in the 1+PRN group was more than that of the 3+PRN group [1(0, 2)times vs 0(0, 1)times, P<0.05].CONCLUSION: Two regimens were both safe and effective in the treatment of pathological myopic CNV by Conbercept, which can improve BCVA, decrease CMT, and reduce CNV area, with less total times of injection in the 1+PRN regimen, and less times of reinjection in the 3+PRN regimen.
