Long-term prognosis of stroke rehabilitation is associated with a number of factors, such as age, sex, race, lesion sites and sides, lesion nature and various complications. Under-standing these related factors not only contribute to clinical judgement of prognosis, but also provide the basis for the targeted rehabilitation therapy.

Objective To evaluate HRCT typing of solitary pulmonary nodule with resected.Methods 30 cases with solitary plumonary nodules (totally 41) were undergone CT and HRCT scan befor operation.HRCT appearances were retrospectively analyzed and categorized into two types: typeⅠ ground-glass opacity (pure ground-glass opacity, mixed lower opacity, central high opacity with ground opacity ), typeⅡ pure solid opacity.Results TypeⅠ:14 nodules included bronchioloalveolar cell carcinoma (9 nodules) , adenocarcinoma (3 nodules),inflammatory granuloma (1 nodule) and adenoma (1 nodule).TypeⅡ : 27 nodules included adenocarcinoma(13 nodules),bronchioloalveolar cell carcinoma(4 nodules), squamous cell carcinoma(3 nodules),small cell lung cancer(1 nodule),adenoma(2 nodules),tuberculosis(2 nodules), inflammatory granuloma(1 nodule) and hamartoma(1 nodule). Among nodules with resected, ground-glass opacity was found more frequently in bronchioloalveolar cell carcinoma than in non- bronchioloalveolar cell carcinoma (P=0.002).No significant difference in ground-glass opacity existed between tumor lesions and non-tumor lesions (P=0.282) or adenocarcinoma and non-adenocarcinoma (P=0.146).Conclusion In the findings of HRCT in solitary pulmonary nodules,the nodules of ground-glass opacity find more frequently in bronchioloalveolar cell carcinoma than that in other lesions.

Objective Toexplore the application value of diffusion tensor imaging (DTI) in evaluating evaluation offunctional changes of the in patients with primary trigeminal neuralgia caused (PTN) by neurovascular compression. Methods 40 unilateral PTN patients and 40 healthy volunteers were enrolled in ourstudy.They allAll patients underwent the general sequences and DTI ,and then to measured the ADC and FA values of the trigeminal nerves. Results (1) Compared with contralateral side (0.408 ± 0.054)and bilateral sides in control group(0.423 ± 0.057), FA value of the ipsilateral side in PTN group(0.330 ± 0.056) was significant lower (P< 0.05)compared with the contralateral side (0.408 ± 0.054) and bilateral sides in control group (0.423 ± 0.057).The ADC value of ipsilateralside (2.052 ± 0.473)× 10-3 mm2/s was significantly higher (P < 0.05) thancompared withthe contralateral side (1.541 ± 0.266) ×10-3 mm2/s and bilateral sides in control group(1.431 ± 0.308) ×10-3 mm2/s. (2) An There's a nnegative correlation was found (r = -0.613,P < 0.001) between the loss of FA and the increase of ADC (r = -0.613,P < 0.001). Conclusion DTI could be used to evaluate the changes of neuratrophy and demyelination ,so it canmight be used of in diagnosis and treatment of PTNin further way.

Objective To research the significance of the levels of neuron-specific enolase(NSE), S100B and myelin basic protein(MBP) in predicting the severity and prognosis in patients with subarachnoid hemorrhage (SAH). Methods The serum levels ofNSE, SI00B and MBPwere measured within 72 hours after the injury in 36 patients with SAH(SAH group), then the severity of illness and prognosis was evaluated by world federation of neurosurgical societies(WFNS) grade and Glasgow outcome scale(GOS) respectively. Twenty healthy persons were selected as controls(control group). Results After the injury, the serum levels of NSE,SI00B and MBP in SAH group increased significantly compared with those in control group. Moreover, there were significant difference in the serum levels of NSE, S100B and MBP among different groups in different severity of illness and prognosis. Assessed the severity and prognosis by serum levels of NSE 25 μg/L, S100B 1.2 μg/L and MBP 10.0 μg/L after 72 hours of SAH, the specificity of assessing the severity by NSE, SI00B and MBP was 71.43%,61.90%, 66.67%, and the sensitivity was 73.33%,86.62% and 73.33%. At assessment of prognosis,the specificity of NSE, S100B, MBP was 69.57%, 60.87%,65.22%, and the sensitivity was 61.54%,76.92% and 69.23%. Conclusion There are higher specificity and sensitivity in evaluating the severity of illnoss and prognosis in patients with SAH by serum levels of NSE, S100B and MBP.

Objective:To establish and validate a malignant risk prediction model of solitary pulmonary nodules (SPNs) with pulmonary fibrosis in long-term smokers based on 18F-flurodeoxyglucose (FDG) PET/CT. Methods:PET/CT images of 222 SPNs combined with pulmonary fibrosis which were shown in integrated CT scan in 169 patients (all males; age 68(63, 75) years) were analyzed retrospectively. All patients were examined in PET/CT Center of the Affiliated Hospital of Qingdao University from January 2011 to December 2019 and all had definite smoking history. The benign and malignant nodules were judged according to the pathological diagnosis or follow-up imaging data of lung lesions (follow-up≥2 years). The clinical characteristics (age, smoking index), morphological characteristics (longest diameter of lesion, density, location, distribution, relative position of fibrosis, spiculation, lobulation, calcification, vacuole, vascular convergence, pleural indentation, emphysema and severity of bilateral pulmonary fibrosis) and metabolic characteristics (maximum standardized uptake value (SUV max)) of the benign and malignant lesions were analyzed by χ2 test and Mann-Whitney U test. Then multivariate logistic regression analysis was applied to select independent risk factors of malignant nodules, and a risk prediction model was established and verified by the area under the receiver operating characteristic (ROC) curve and k-fold cross validation ( k=10) respectively. Results:Among 169 patients, 222 SPNs were detected (157 malignant nodules, 65 benign nodules). Univariate analysis showed that smoking index, speculation, lobulation, vascular convergence sign, calcification, emphysema, nodule size, relative position of nodule and fibrosis, SUV max and severity of bilateral pulmonary fibrosis were significantly different between the benign and malignant nodules ( z values: 2.514-9.858, χ2 values: 4.353-18.442, all P<0.05). Result of multivariate logistic regression analysis showed that calcification, vascular convergence and SUV max were the independent risk factors of malignant nodules combined with pulmonary fibrosis (odds ratio ( OR): 0.048-2.534, all P<0.05). The risk prediction model was as follow: P=1/(1+ e - x), x=-1.839-3.033×calcification+ 0.930×vascular convergence+ 0.754×SUV max(with calcification/vascular convergence=1, without calcification/vascular convergence=0). The area under ROC curve was 0.932(95% CI: 0.895-0.969), and the sensitivity and specificity of the model were 87.9% and 86.2%, respectively. Results of k-fold cross validation showed that the prediction accuracy of 10 test sets was 0.847±0.075, and was 0.862±0.010 in training sets. Conclusions:Calcification, vascular convergence and SUV max are independent risk factors of malignant SPNs combined with pulmonary fibrosis in long-term asymptomatic smokers. The model based on the above variables presents high diagnostic efficiency in diagnosing malignant SPNs.
