Objective To evaluate the applied value of functional immunity measured by the ImmunKnow assay in the diagnosis of post-transplant infection in Chinese 1iver recipients.Methods Thirty-eight normal adults and 68 adult liver transplant recipients were under investigation.Whole blood samples from either normal volunteers(each sample for one person)or the liver recipients(one or more samples for one person)were collected freshly and cultured within 6h.The CD4+T cells were selected and their ATP value was assayed the next day.The liver recipients were grouped in stable status(n=52)or infection(n=64)according tO their clinieal manifestation.Results The average ATP value in the recipients with infection after liver transplantation was 165.7±100 μg/L,significantly lower(P＜0.05)than that in stable recipients(309±126 μg/L)or normal volunteers (292±83 μg/L).The low ATP levels in post-transplant recipients had fair good correlation to infection clinically(RR=0.5021,P＜0.01).Infectious risk was high when ATP value was less than 165μg/L(OR=11,95%CI 3.9-32.2,P＜0.01).Specificity and sensitivity of low ATP value in post-transplant infection were 86.53%and 73.81% respectively,Conclusion ImmuKnow assay provides a new tool in monitoring immune status in post-transplant recipients,and call helpfully predict and diagnose clinical infection.

Objective To assess the diagnostic accuracy of solitary pulmonary nodules while selecting different backgrounds in 99 Tcm‐MIBI SPECT/CT examination .Methods Totally 38 suspected solitary pulmonary nodules (SPN) were analyzed retrospectively .The lesions were divided into malignant group and benign group according to the pathological findings . We selected two different backgrounds , contralateral lung field ( DL ) and the contralateral soft tissue (NST) .The maximum counts and the mean counts of lesion to non‐lesion ratio (L/N) were calculated to evaluate diagnostic efficacy using ROC curve . The relationship between lesion size , pathological grading and L/N ratio was analyzed by Spearman correlation analysis . Results With DL and NST as the backgrounds ,the maximum counts and the mean counts of L/N between benign and malignant groups both differed significantly (all P<0 .05) .ROC curve analysis showed as follows :With DL and NST as the backgrounds ,the area under the curve (AUC) of L/DL‐MAX ,L/DL‐MEAN ,L/NST‐MAX ,and L/NST‐MEAN was 0 .73 ,0 .78 ,0 .80 and 0 .86 ,respectively .By pairwise comparison ,there was no significant difference (all P>0 .05) .The size and pathological grading of SPN did not affect 99 Tcm‐MIBI accumulation in the SPN (all P>0 .05) .Conclusion DL and NST both can be used as the background in diagnosis of pulmonary nodules on 99 Tcm‐MIBI SPECT/CT examination .The mean counts of the contralateral tissue used as the background can provide a stable result and a high diagnostic accuracy to assess the SPN .

Objective To observe the energy consumption of children with cerebral palsy before and after assisted walking. Methods From January, 2014 to October, 2015, 21 children in primary school of Grades 1~5 (control group) and 22 children with cerebral palsy in our hospital (observation group) were enrolled. They were required to walk in the 50 meters trail for six minutes. The resting heart rate, the walking distance and the heart rate after walking were measured, and the walking speed and the physical consumption index (PCI) were cal-culated. The observation group was tested with and without forearm crutches. Results Compared with the control group, the walking dis-tance and speed significantly decreased (t>10.653, P<0.001), and the PCI significantly increased (t>4.207, P<0.001) in the observation group. For the observation group without forearm crutches, the heart rate after walking, and the difference of the heart rate significantly de-creased (t=8.389, P<0.001), and the walking distance, walking speed and PCI decreased (t>2.382, P<0.05) when they walked with forearm crutches. Conclusion Assisted walking can decrease the energy consumption of children with cerebral palsy.
