Objective To assess the predictive value of neutrophil gelatinase associated protein lipocalin (uNGAL) in urine for detection of acute kidney injury(AKI) in patients with severe traumatic brain injury. Methods Patients with severe traumatic brain injury from the ICU were collected from Jan. 2011 to May. 2013 in our hospital. 43 cases that met the RIFLE criteria for diagnosis of AKI in the ICU within 7 days were selected as AKI group. Another 43 cases that were matched for age ,gender ,illness severity , surgery method with AKI cases ,selected as non‐AKI group. The levels of uNGAL and Scr were measured when the patients admit‐ted in the ICU with 15 min ,at 24 h ,48 h ,72 h. the sensitivity and specificity of uNGAL and Scr for diagnosis for AKI were evalua‐ted by ROC curve. Results The incidence of severe traumatic brain injury AKI was 42. 16% (43/102). The uNGAL levels in the AKI group were higher when the patient stayed in the ICU longer and no obvious in the non AKI group. When admitted to the ICU 24 h ,the level of uNGAL(720. 32 ± 684. 25)ng/mL in AKI group was significantly higher than that (421. 92 ± 351. 20)ng/mL in non AKI group. The difference was statistically significant (P< 0. 05). The levels of Scr between two groups were not statistically significant. The area under ROC curve of uNGAL and Scr were 0. 879 (95% CI :0. 807 - 0. 949) and 0. 612 (95% CI :0. 493 -0. 731). When the cutoff value of uNGAL was 180 ng/mL ,the sensitivity and specificity were 0. 890 and 0. 823 respectively. The sensitivity was superior to Scr. Conclusion uNGALis superior to Scr for early diagnosis of AKI in patients with severe traumatic brain injury and it could be used as a biomarker for early diagnosis of AKI.

Objective:
To establish a nomograph model for prediction of cervical central lymph node metastasis (CLNM) among patients with thyroid papillary carcinoma (PTC), so as to provide the evidence for designing personalized treatment plans for PTC.
Methods :
The data of patients that underwent thyroidectomy and were pathologically diagnosed with PTC post-surgery in the Affiliated Traditional Chinese Medicine Hospital of Xinjiang Medical University from 2018 to 2021 were collected. Patients' data captured from 2018 to 2020 and from 2021 were used as the training set and the validation set, respectively. Predictive factors were screened using a multivariable logistic regression model, and the nomograph model for prediction of CLNM risk was established. The predictive value of the model was evaluated using the receiver operating characteristic (ROC) curve and the adjusted curve.
Results:
Totally 1 820 PTC cases were included in the training set, including 458 cases with CLNM (25.16%), and 797 cases in the validation set, including 207 cases with CLNM (25.98%). The prediction model is p=ey/(1+ey), y=0.761 + 0.525 × sex + (-0.039) ×age + 0.351 × extrathyroid invasion + 0.368 × neck lymph node enlargement + 1.021×maximum tumor diameter + (-0.009) × TT4 + (-0.001) × anti-TPOAb. The area under the ROC curve was 0.732 for the training set and 0.731 for the validation set, and Hosmer-Lemeshow test showed a good fitting effect (P=0.936, 0.722).
Conclusion

BACKGROUND: Iliac bones are common habitant parts in metastatic tumor of bone, and the affiliate cortex is easy to be penetrated into soft tissue blots. The irregular iliac shape and its complex surrounding tissues create the difficulties in puncture operations and cement perfusion.OBJECTIVE: To investigate the clinical outcomes of CT-guided versus DSA-guided puncture combined with bone cement perfusion for metastatic tumor to the ilium.METHODS: Sixty-four patients with metastatic tumor to the ilium udergoing bone cement perfusion were enrolled, and then divided into control and experimental groups (n=32 per group), followed by treated with DSA-guided percutaneous injection of bone cement, and CT-guided puncture, respectively. Subsequently, the diffuse distribution of bone cement was observed using CT. The success rate, leakage rate, Visual Analogue Scale scores and Oswestry Disability Index were compared between two groups.RESULTS AND CONCLUSION: (1) All patients received the surgery successfully, and bone cement leakage happened in two cases of control group and one case of experimental group. (1) The Visual Analog Scale and Oswestry Disability Index scores in the two groups were significantly better than those before treatment (P < 0.05), and the scores showed no significant differences between two groups (P > 0.05). (3) No difference was found in the pain relief and functional recovery between two groups. (4) To conclude, CT-guided treatment can achieve satisfactory outcomes for metastatic tumor to the ilium by bone cement infusion in appropriate time.

Objective: To explore the effect and safety of pre-operative loading ticagrelor on myocardium reperfusion in patients with acute ST-elevation myocardial infarction (STEMI) during primary percutaneous coronary intervention (PCI). Methods: A total of 105 acute STEMI patients received PCI within 12-hour of onset were studied and they were divided into 2 groups: Ticagrelor group, the patients received pre-operative oral chewing ticagrelor 180 mg,n=58 and Clopidogrel group, the patients received pre-operative oral chewing clopidogrel 600 mg,n=47. The baseline feathers, operative TIMI and corrected TIMI frame count (CTFC), TIMI myocardial perfusion grade (TMPG), no-relfow/slow lfow conditions were compared between 2 groups. Results: The baseline feathers and pre-operative TIMI were similar between 2 groups, bothP>0.05. Compared with Clopidogrel group, Ticagrelor group showed increased ratios of TIMI 3 lfow (94.8% vs 80.9%) and TMPG (89.7% vs 72.3%), bothP<0.05, improved CTFC (20.0 ± 4.9) vs (31.8 ± 3.9),P<0.001; decreased rates of no-relfow/slow lfow,P=0.016 and less MACE occurrence,P<0.05; while the post-operative bleeding events were similar between 2 groups,P>0.05. Conclusion: Prior PCI loading ticagrelor may reduce no-relfow/slow lfow incidence, improve myocardium reperfusion safely and therefore, decrease MACE occurrence in acute STEMI patients.

Objective: To investigate thoracic endovascular aortic repair (TEVAR) and “Chimney” technique for treating the involved left common carotid artery (LCCA) or left subclavian artery (LSA) in Standford B patients with aortic lesion and in-sufficient proximal anchoring area. Meanwhile, to explore the relationship between endoleaking condition and the location of lesion with the prognosis. Methods: A total of 32 relevant patients treated by TEVAR + “Chimney” technique in our hospital from 2011-09 to 2015-07 were retrospectively analyzed. Immediate post-operative image development of LCCA or LSA was observed; cerebral complications, severe upper limb ischemic symptoms and endoleaking conditions were recorded. The patients were followed-up for (3-46) months. Results: Thoracic aortic stent-graft placement was successfully carried out in all 32 patients. Immediate post-operative image development of LCCAor LSAwas favorable, no cerebral complications and no severe upper limb ischemic symptoms were observed. There were 7 patients suffered from endoleak at aortic arch including 6 with the lesion located at the greater curvature side and 1 at the small curvature side. During follow-up period, aortic stent-graft remained in a stable condition and the blood flow in “Chimney” stent was unobstructed. Endoleking condition was gradually reduced and disappeared in 5 patients, it was persisted in 2 patients. Conclusion: “Chimney” technique may prolong anchoring area and keep LCCA or LSA unobstructed, therefore expand the indication of TEVAR in a mini-invasive, safe and effective way. When aortic lesion located at the greater curvature side, the endoleaking probability could be increased.
