ABSTRACT
Objective:To investigate the effect of conventional coronary CT angiography (CCTA) bolus injection of contrast agent on the diameter and angle of the left main coronary artery (LMA) bifurcation area, and to provide a basis for the application of CCTA to accurately measure the coronary artery.Methods:In Cangzhou Central Hospital of Hebei Province from January to December 2020, the clinical data of 54 patients with suspected coronary heart disease who underwent coronary artery calcification score (CACS) and CCTA with conventional bolus injection of contrast agent were retrospectively analyzed. Two physicians measured middle lumen diameter of LMA (d1), proximal lumen diameter of left anterior descending (LAD) (d2), proximal lumen diameter of left circumflex (LCX) (d3) and bifurcation angle between LAD and LCX (∠1). The consistency of 2 physicians was compared, and the results of CACS and CCTA were compared.Results:The consistency analysis result showed that only d3 measured by CCTA had a moderate consistency (intra-group correlation coefficient = 0.717), and the remaining indexes were in good agreement (intra-group correlation coefficient >0.75). There were no statistical differences in indexes measured results between CACS and CCTA ( P>0.05). According to the degree of left coronary artery stenosis, 54 patients were divided into 2 groups: LMA and branches normal or stenosis degree < 50% group (25 cases) and LMA and branches 1 or more branches stenosis degree≥50% group (29 cases). There were no statistical differences in indexes measured results between CACS and CCTA in patients with different disease severity ( P>0.05). Conclusions:In the CCTA examination, the conventional bolus injection of contrast agent does not affect the diameter and angle of the lumen of the LMA bifurcation area of the coronary artery.
ABSTRACT
Objective To investigate the effect of Wushen decoction on levels of serum cardiac troponin Ⅰ (cTnI),cardiac muscle enzyme and clinical parameters in patients with sepsis heart failure,and to analyze the correlations between cTnI and myocardial enzyme level and clinical parameters.Methods Forty-two patients diagnosed as sepsis admitted to Wuhan Hospital of Traditional Chinese Medicine from March 2014 to March 2016 were enrolled,and they were divided into a Wushen decoction treatment group and a control group by principle of single blind complete randomized method,21 cases in each group.The patients in control gToup were treated by conventional western medicine,while the patients in Wushen decoction treatment group,on the basis of conventional western medicine,they were treated additionally by Wushen decoction (composed of ginseng,radix sophorae flavescentis,radix glehniae,radix adenophorae,salvia,astragalus,notoginseng radix,rosewood,etc.),one dose a day,the therapeutic course in both groups being 7 days.The changes of biochemical indicators [cTnI,creatine kinase (CK),CK isoenzyme (CK-MB)],haemodynamics parameters [cardiac index (CI),central venous pressure (CVP),extravascular lung water index (ELWI),global ejection fraction (GEF),mean arterial pressure (MAP),heart rate (HR)],treatment condition and prognostic parameters [vasoactive drug dosage index,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,duration of mechanical ventilation,the length of stay in intensive care unit (ICU) and total hospitalization time] were compared before and after treatment for 7 days in the two groups.The correlations between the level of cTnI on admission before treatment and CK,CK-MB,APACHE Ⅱ,vasoactive drug dosage index,duration of mechanical ventilation,the length of stay in ICU and total hospitalization time were analyzed.Results The levels of cTnI,CK,CK-MB,CVP,ELWI,HR,vasoactive drug dosage index,APACHE Ⅱ score in two groups after treatment were obviously lower than those before treatment,the levels of CI,GEF,MAP were markedly higher than those before treatment,the duration of mechanical ventilation,the length of stay in ICU and total hospitalization time were significantly shorter than those before treatment,and the changes of above indexes were more remarkable in Wushen decoction group than those in control group [cTnI (mg/L):0.94-± 0.29 vs.1.30 ± 0.67,CK (U/L):96.00 ± 24.30 vs.101.38 ± 24.55,CK-MB (U/L):31.14 ± 6.78 vs.36.48 ± 8.17,CI (mL· s-1 · m-2):64.51 ± 5.83 vs.53.34 ± 4.67,CVP (cmH2O,1 cmH2O =0.098 kPa):10.56 ± 1.84 vs.11.94--2.16,ELWI (mL/kg):8.81±1.61 vs.11.66±2.30,GEF:(33.62±3.88)％ vs.(27.14±4.55)％,MAP (mmHg,1 mmHg =0.133 kPa):84.67 ± 5.58 vs.79.52 ± 5.74,HR (bpm):87.86 ± 9.02 vs.82.95 ± 5.26,vasoactive drug dosage index:2.44 ± 0.53 vs.2.89 ± 0.68,APACHE Ⅱ score:10.66 ± 1.66 vs.14.43 ± 1.82,duration of mechanical ventilation (days):1.67 ± 2.11 vs.2.10 ± 2.26,the length of stay in ICU (days):8.86 ± 2.59 vs.10.67 ± 2.96,total hospitalization time (days):13.24 ± 4.53vs.16.76 ± 5.04,all P ＜ 0.05].On admission before treatment,the correlations between the level of cTnI and CK,APACHE Ⅱ score,vasoactive drug dosage index,duration of mechanical ventilation and the length of stay in ICU were all positive (r =0.322,0.335,0.327,0.328,0.338,P =0.038,0.030,0.030,0.034,0.029).Conclusions The elevation of cTnI level may reflect the degree of myocardial damage in patients with sepsis cardiac failure,and it can be used as an indicator to predict the prognosis of the disease;the changes of many biochemical and clinical indexes suggest that the addition of Wushen decoction might elevate the clinical efficacy for treatment of patients with sepsis heart failure.
ABSTRACT
Objective:To investigate the protective effect of Epigallocatechin-3-gallate (EGCG) on triptolide (TP)-induced immunological liver injuries, and explore the relevant mechanisms of action. Methods: A total of 40 female C57BL/6 mice were randomly divided into four groups:control group,EGCG group,TP group and TP+EGCG group. The ALT levels in serum was examined by Reitman Frankel method. The activity of hepatic MDA,SOD and GSH was examined by spectrophotometry. HE staining was used to observed the changes of the hepatic histopathology. The hepatic IL-17,IL-6 levels was examined by ELISA and the expression of hepatic TLR4 protein was examined by Western blot. Results:The results showed that serum alanine aminotransaminase ( ALT) levels of TP group were obviously elevated (P0. 05). Meanwhile,EGCG could ameliorate hepatic pathological damage. Furthermore,in TP group,the activity of malondialdehyde ( MDA) ,the expression of Toll-like receptor 4 (TLR4) protein and the contentration of hepatic interleukin (IL)-17,IL-6 were higher than normal control group ( P<0. 005 ) . On the contrary, the activity of superoxide dismutase ( SOD ) and restored glutathione ( GSH ) were significantly lower than normal control group ( SOD, P<0. 05;GSH, P<0. 005 ) . In EGCG treatment group, the expression of TLR4 protein and the concentration of MDA,hepatic IL-17 and IL-6 were lower than TP group ( TLR4,P<0. 05;MDA,P<0. 005;IL-17,P<0. 005;IL-6,P<0. 005). On the contrary,SOD and GSH were significantly higher than TP group (SOD,P<0. 05;GSH,P<0. 005). Conclusion:This study suggests that EGCG possesses hepatoprotective effect against TP-induced immunological liver injury through its anti-inflammatory and anti-oxidant actions.
ABSTRACT
Objective To observe the therapeutic efficacy of acupuncture at the thirteen ghost points in treating postpartum depression and its effect on the quality of life. Methods Sixty patients with postpartum depression were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupuncture at the thirteen ghost points, while the control group was by oral administration of Fluoxetine. The Hamilton Rating Scale for Depression (HAMD) and the Short-Form (36) Health Survey (SF-36) were compared before and after intervention. Results The HMAD score was significantly changed in both groups after intervention (P＜0.05). There was a significant difference in comparing the HAMD score between the two groups after intervention (P＜0.05). There were significant differences in comparing the post-treatment bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), mental health (MH), and health transition (HT) between the two groups (P＜0.05). Conclusion Acupuncture at the thirteen ghost points can effectively improve the postpartum depression and the quality of life.
ABSTRACT
Objective To explore the CT,clinical,and pathological features of eosinophilic lymphogranuloma(ELG)in head and neck region. Methods CT,clinical,and pathological data of 9 cases of ELG in head and neck region,confirmed by biopsy were retrospectively an-alyzed.Results Parotid gland was lonely involved in 3 cases,and cervical lymph nodes were lonely involved in 2 cases,and they were both involved in 4 cases.All of the patients suffered from painless nodule or mass in head and neck region with peripheral blood eosinophilia.On CT examination,nodular lesions of parotid gland were clear or slightly blurred defined with moderately or obviously homogeneous enhancement,and diffuse mass lesions in parotid gland were ill defined with involvement of surrounding tissue,and heterogenous progressive enhancement.The involved cervical lymph nodes were enlarged with clear boundaries,and moderately or obviously homogeneous enhancement.The pathological findings of ELG included the marked infiltration of eosinophilia,lymphocytic proliferation,lymphatic follicles,variable degrees of fibrosis and vascular proliferation.Conclusion ELG in head and neck region has some CT features,and diagnosis could be suggested combining with the clinical manifestations and peripheral blood eosinophilia. The final diagnosis depends on histopathological examination.
ABSTRACT
OBJECTIVE@#To evaluate MSCT diagnostic value in children with foreign body and stenosis in trachea and bronchus.@*MATERIALS AND METHOD@#MSCT scan was done in 18 children suspected foreign body and stenosis in trachea and bronchus. Postprocessed (included Minp and MPR) were done after the axial images were obtained. All of 18 cases underwent conventional BFS.@*RESULT@#Fifteen cases were shown with foreign body through MSCT scan. In addition, total amount of foreign body reached 21 pieces; The CT value in one case was 278 HU, in the others were from--10.6 HU to 31 HU; Stenosis in trachea and bronchus was found in 2 cases; Stenosis in laryngeal cavity after foreign body removing in one case. Foreign body and stenosis in trachea and bronchus were shown better in MPR and Minp images. MSCT images were not only conformed to BFS completely, but also showing foreign body in segmental bronchus more accurately.@*CONCLUSION@#MSCT scanning could show direct and indirect signs of the foreign body and stenosis in trachea and bronchus accurately, and determine the nature of foreign body. It can act as a primary examination.
