Objective To explore the effect of 3M Tegaderm transparent film on prevention of puncture complications in patients underwent aortocranial angiography via the femoral artery.Methods A retrospective analysis was carried out on 200 patients underwent aortocranial angiography via the femoral artery from February 2012 to February 2014.Eighty patients without using the transparent dressing paste were as the control group,and other 120 patients using 3M Tegaderm transparent film for fixation of arterial sheath were as the observation group.The occurrences of complications,such as arterial sheath breakage,angiographic tube breakage,femoral artery spasm,bruises at the puncture site and subcutaneous hematoma were analyzed,and the feasibility and effectiveness of 3M Tegaderm transparent film for fixation of arterial sheath were assessed.Results The incidence rate of arterial sheath breakage,angiographic tube breakage,femoral artery spasm,bruises at the puncture site and subcutaneous hematoma were significantly reduced in observation group compared with those in control group [5.8％ (7/120) vs.26.2％ (21/80)] (P ＜ 0.05).Conclusion Application of 3M Tegaderm transparent film with a low price and good security for fixation of femoral artery sheath can effectively reduce the occurrence of complications related to femoral artery puncture,which is worthy of wide spreading.

Objective The chief aim of the present work is to investigate features of sternum of Chinese adults and to establish the sex determination method to evaluate its effect based on 3D recombinant morphology indicators. Methods Based on chest spiral CT scans, 2D images of multi-level recombination and 3D model of volume rendering, the experiment concludes an sex determination equation from 8 measurement indicators of the sternum and 3 ratio indicators. The 8 measurement indicators include full-length, handle length, body length, maximum width of the handle, maximum width of the body, maximum thickness of the handle, maximum thickness of the body, and thickness of the upper body. Results According to the 11 indicators of sex differences in statistics (P<0.05), especially indicators of the full-length, body length, maximum width of the handle and maximum thickness of the body, the body's sex is easier to be determined. All indicators equations, length indicators discriminant equations and stepwise discriminant equations have higher reliable rate (88.6%) which was consistent with the recent foreign research reports. Conclusion The method of sex determination based on multislice spiral CT 3D recombinant techniques is practicable and has an relatively high accuracy. It is expected to be applied to researches in age estimation by sternum and other virtual bones.

Objective:To analyze the diagnostic value of thickness ratio between noncompacted and compacted myocardium (NC/C ratio) measured by echocardiography at end-systole and end-diastole comparatively in left ventricular noncompaction (LVNC).Methods:Thirty-five patients with suspected LVNC were collected and underwent conventional (2DE) and left ventricular opacification (LVO) in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from June 2019 to June 2020. The distribution and detection rate of two-layered segments, non-compaction (NC) segments and their NC/C ratios were comparatively analyzed at end-diastole and end-systole using 2DE, LVO and combined techniques respectively. With the diagnostic criteria of end-diastolic NC/C ratio>2.3 or end-systolic NC/C ratio>2.0, echocardiographic results were also recorded and compared with cMRI results.Results:Compared with 2DE, the number of detected segments was increased ( P<0.001), but the numbers of two-layered segments and NC segments were not significantly improved in end-systole using 2DE combined with LVO ( P>0.006). The diagnostic accuracy was not statistically significant ( P>0.05). However, when observing in end-diastole, the detected numbers of 3 kinds of segments were significantly increased using 2DE+ LVO in comparison with 2DE (all P<0.001), and the diagnostic accuracy was also significantly improved ( P<0.05). There were no significant differences in the detected rates of two-layered and NC semgents between 2DE+ LVO and cMRI ( P>0.006). 2DE+ LVO in end-diastole resulted in the highest diagnostic sensitivity (88.9%) and accuracy (85.7%), and also the largest area under ROC curve (0.95). Conclusions:The combination of 2DE and LVO can detect more NC segments, and diagnostic accuracy of end-diastolic NC/C ratio is higher than that in end-systolic in patients with LVNC.

Objective To determine the relationship between serum soluble Klotho (sKL) level and adverse outcome in maintenance hemodialysis (MHD) patients.Methods One hundred and twenty nine cases of MHD patients were collected prospectively.Serum sKL was detected by ELISA.Abdomen lateral plain was used as a criterion to determine the abdominal aortic calcification.The abdominal aortic calcification score (AAC) was calculated.Cox regression analysis was used to determine the risk factor of cardiovascular death (CVD) in MHD patients.Kaplan-Meier showed the relationship between sKL and CVD in MHD patients.Results There were 27 cases (20.9％) of allcause death and 19 cases (14.7％) of cardiovascular death.The median sKL was 612.6(379.2-816.6) nig/L,and log[iPTH] was an independent factor of sKL concentration.Low sKL had high AAC and CVD death rate.Kaplan-Meier method showed that the all-cause death rate was similar between two groups,and CVD death rate increased significantly in low sKL patients (P=0.036).Cox regression indicated that lower sKL level was associated with high CVD death rate [OR=0.352,95％CI(0.127-0.977),P=0.045].After adjustment for the general condition,biochemical indicators,the relationship still existed [OR=0.331,95％ CI (0.117-0.933),P=0.037].In no or mild vascular calcification patients (AAC ≤4),compared with high sKL patients,low sKL patients had no significant difference rate in all-cause mortality.The CVD mortality was significantly higher in high sKL (P=0.035) compared with low sKL.In severe calcification group (AAC ＞ 4),all-cause death and CVD death rates were similar between different sKL groups (P=0.991 and 0.522,respectively).Conclusions Lower sKL has the high CVD death rate and sKL level decreasing is an independent risk factor for CVD death in MHD patients.The lower sKL concentration in MHD patients with no or mild calcification may predict CVD mortality.This study suggests that sKL levels may be helpful in predicting the outcome of patients with MHD.

BACKGROUND/AIMS: The relationship between C-peptide levels and gastrointestinal (GI) symptoms in type 2 diabetic patients is not clear. The purpose of this study is to examine the association between fasting C-peptide and GI symptoms of gastroparesis in type 2 diabetic patients. METHODS: We recruited 333 type 2 diabetic patients into the present study. All patients filled out questionnaires of gastroparesis cardinal symptom index (GCSI) to evaluate GI symptoms. Hospital anxiety and depression scale were adopted to define anxiety and depression. Patients with GCSI scores ≥ 1.9 were regarded as having symptoms of gastroparesis. RESULTS: In our study, 71 (21.3%) type 2 diabetic patients had GCSI scores ≥ 1.9. In comparison to patients with scores < 1.9, those with scores ≥ 1.9 had significantly lower fasting c-peptide levels (1.49 ng/mL vs 1.94 ng/mL, P < 0.001), higher prevalence of depression (40.9% vs 18.3%, P < 0.001) and anxiety (28.2% vs 13.0%, P = 0.002). Multivariate logistic regression revealed that fasting C-peptide was still significantly associated with symptoms of gastroparesis (odds ratio, 0.67; 95% confidence intervals, 0.48–0.94; P = 0.021), even after adjustments for age, sex, body mass index, HbA1c, current smoking and drinking status, anxiety, and depression. Furthermore, linear regressions showed that fasting C-peptide was independently and negatively related to GCSI scores (standardized regression coefficient, −0.29; P < 0.001) in patients with at least one GI symptom. CONCLUSION: GI symptoms of diabetic gastroparesis affect approximately 20% of type 2 diabetes patients and are associated with lower fasting C-peptide levels independent of depression and anxiety status.
