Pooled sensitivity, specificity and the diagnostic odds ratios (DORs) with 95%CI were calculated for each study and were compared to other systems/biomarkers if mentioned within the same study. Summary receiver-operating curves were conducted and the area under the curve (AUC) was evaluated.RESULTS: In total, six studies of uTAP with a cut-off value of 35 nmol/L were included in this meta-analysis. Overall, the pooled sensitivity and specificity of uTAP for predicting severity of acute pancreatitis, at time of admission, was 71% and 75%, respectively (AUC = 0.83, DOR = 8.67, 95%CI: 3.70-20.33). When uTAP was compared with plasma C-reactive protein, the pooled sensitivity, specificity, AUC and DOR were 0.64 vs 0.67, 0.77 vs 0.75, 0.82 vs 0.79 and 6.27 vs 6.32, respectively. Similarly, the pooled sensitivity, specificity, AUC and DOR of uTAP vs Acute Physiology and Chronic Health Evaluation II within the first 48 h of admission were found to be 0.64 vs 0.69, 0.77 vs 0.61, 0.82 vs 0.73 and 6.27 vs 4.61, respectively.CONCLUSION: uTAP has the potential to act as a stratification marker on admission for differentiating disease severity of acute pancreatitis.展开更多

The patients in the two groups were given routine drugs for conservative treatment. On this basis, the patients in the observation group were given HUK. NSE and S-100 protein before treatment, 3, 7, 14, and 28 d after treatment in the two groups were compared. TCD was used to detect the cerebral hemodynamics. NIHSS and BI were used to evaluate the improved degree of neurological function and daily living activities before treatment, 1 and 3 months after treatment.Results: NSE and S-100 protein 3, 7, 14, and 28 d after treatment in the observation group were significantly lower than those in the control group (P<0.05). The blood flow rate of left vertebral artery, right vertebral artery, and basilar artery after treatment in the two groups was significantly elevated (P<0.05). The blood flow rate of left vertebral artery, right vertebral artery, and basilar artery after treatment in the observation group was significantly higher than that in the control group (P<0.05). NIHSS and BI scores 1 and 3 months after treatment in the observation group were significantly superior to those in the control group (P<0.05).Conclusions: HUK can effective reduced the brain tissue injury in patients with acute cerebral infarction, and promote the recovery of neurological function, with an accurate efficacy.展开更多
