Objective To investigate the neuroprotective effect and possible mechanism of Compound Porcine Cerebroside and Ganglio-side Injection (CPCGI) on cerebral ischemia-reperfusion injury in rats. Methods Healthy adult male Sprague-Dawley rats were divided into sham group (n=10), model group (n=10), CPCGI low dosage group (n=10) and high dosage group (n=10), and control group (Ginkgo biloba extract, n=10). All the rats was subjected to middle cerebral artery occlusion (MCAO) for two hours and reperfusion except sham group, and received treatment for fourteen days once reperfusion started. They were tested with modified Neurological Severity Score one, three, seven and fourteen days after MCAO, and adhesive-removal test and beam-walking test fourteen days after MCAO. The expression of Beclin1, PINK1 and Parkin were detected with Western blotting. Results Compared with the model group, the Neurological Severity Score reduced (P<0.05) and the time crossing the beam reduced (P<0.01) in all the medical groups fourteen days after MCAO, and the time removing the adhesive paper reduced in the CPCGI groups (P<0.01). The expression of Beclin1 and Parkin decreased and the PINK1 level increased in the model group (P<0.01), and it was reversed in all the CPCGI groups (P<0.05). Conclusion CPCGI could relieve the cerebral ischemia-re-perfusion injury in rats through the regulation in mitophagy.

Objective:To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) for hemorrhagic transformation (HT) in patients with acute ischemic stroke (AIS).Methods:Consecutive patients with AIS without performing intravenous thrombolysis and mechanical thrombectomy admitted to the Cerebrovascular Disease Treatment Center, the Affiliated Brain Hospital of Nanjing Medical University from December 2015 to December 2020 were enrolled. The clinical, imaging and laboratory examination data were collected. HT was defined as the first imaging examination of AIS patients without finding bleeding signs, but the imaging reexamination after hospitalization found intracranial hemorrhage. Multivariate logistic regression analysis was used to determine the independent correlation between NLR and HT. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR for HT. Results:A total of 805 patients with AIS were included. The median age was 67 years (interquartile range, 63-71 years), the median National Institutes of Health Stroke Scale (NIHSS) score was 4 (interquartile range, 2-9), the median NLR was 3.84 (interquartile range, 2.66-5.30). Seventy-ywo patients (8.9%) had HT. There were significant differences in age, baseline systolic blood pressure, baseline NIHSS score, time from onset to admission, time from onset to blood collection, time from onset to imaging reexamination, NLR, atrial fibrillation, history of previous stroke and transient ischemic attack and stroke etiology between the HT group and the non-HT group (all P<0.05). Multivariate logistic regression analysis showed that NLR was an independent risk factor for HT in patients with AIS after adjusting for confounding factors (odds ratio 1.355, 95% confidence interval 1.099-1.672; P=0.005). The ROC curve analysis showed that the area under the curve of NLR predicting HT was 0.852, and the optimal cut-off value was 4.75. Its sensitivity and specificity of predicting HT were 88.3% and 71.8% respectively. Conclusion:High NLR is an independent risk factor for HT in patients with AIS during hospitalization, and had better predictive value for HT risk.

According to the literature review, no cyst of the hip ligamentum teres has been reported. In this study, a 50?year?old female patient was admitted to the hospital because of sprained left hip pain with movement restriction for 15 months. The unilateral hip joint MRI showed cyst of the hip ligamentum teres, which was diagnosed as left hip joint cyst in the outpatient de?partment. Thus, the patient was admitted to the hospital. Physical examination showed that the left hip joint movement was slightly restricted with positive FADDIR test and FABER test. Arthroscopic surgical examination revealed a 1.5 cm×1.0 cm cyst at the lo?cation of the round ligament which was then cleared with a planer knife and radiofrequency. The treatment results were satisfacto?ry. The present study reviewed the literature about anatomical and biomechanical physicochemical properties of the ligamentum teres. The function of the ligamentum teres is important for the hip joint. In diagnosis of hip disease, unilateral hip MRI plays an important role in accurate diagnosis of such diseases. The hip arthroscopy provide a minimal invasive technique in treating cyst of the hip ligamentum teres. With the application of the hip arthroscopy, it will undoubtedly improve the diagnosis and treatment of hip diseases.

BACKGROUND:Bone mineral density is the clinical gold standard for determining bone strength,but bone mineral density is less sensitive to changes in bone mass,with large changes in bone mineral density only occurring when bone mass is significantly reduced,so bone mineral density has limited ability to predict changes in bone strength and fracture risk. OBJECTIVE:A model of the normal and osteoporotic hip joint was developed to analyze the stresses and deformation in the hip of normal and osteoporotic patients under single-leg standing conditions. METHODS:A healthy adult female volunteer at the age of 36 years was selected as the study subject.The CT data of the hip joint of this volunteer were obtained and saved in DICOM format.The hip joint model was reconstructed in three dimensions,and the material properties were assigned by the gray value assignment method to obtain the normal and osteoporotic hip joint models according to the empirical formula.The same boundary conditions and loads were set to simulate the stresses and deformation in the normal and osteoporotic hip joints in the single-leg standing position. RESULTS AND CONCLUSION:(1)In the finite element model of the normal and osteoporotic hip,the stress distribution was more concentrated in the medial region of the femoral neck.(2)In the hip bone,the stress distribution was mainly concentrated in the upper part of the acetabulum.(3)The stress peaks in the medial femoral neck and upper acetabulum were larger in the normal hip model than in the osteoporotic hip model,probably due to the reduced bone strength of the osteoporotic bone.(4)The peak Von Mises of both normal and osteoporotic hip models were concentrated on the medial femoral neck,and the peak Von Mises of the hip bone was smaller,indicating that the overall effect of osteoporosis on hip bone stresses was relatively small.(5)In terms of deformation in the single-leg standing position,the maximum deformation in the normal hip model was located at the acetabulum and femoral head,and the maximum deformation was located at the upper part of the greater trochanter of the femur.(6)It is suggested that the finite element analysis method to model the values of parameters related to bone tissue in osteoporosis may improve clinical prediction of bone strength changes and fracture risk.It is explained from the biomechanical view that the intertrochanteric femur and femoral neck are good sites for osteoporotic hip fractures.
