BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) as common seed cells have been widely used in tissue-engineered cartilage repair.OBJECTIVE: To use human amniotic membrane as a cell scaffold to carry rabbit BMSCs in order to repair articular cartilage defects in the femoral intercondylar fossa of rabbits.METHODS: Rabbit BMSCs were inoculated onto the human acellular amniotic membrane (HAAM) and co-cultured for 2 weeks. Articular defect models were made in the femoral intercondylar fossa of rabbits. The defects of the right knees served as blank control. BMSCs/HAAM composite was transplanted into the defect of the left knee joint as composite group, and HAAM was implanted into the defect of the left knee joint as HAAM group. These rabbits were killed at 8 and 12 weeks after implantation and the newly cartilage samples were evaluated grossly and histologically and then graded.RESULTS AND CONCLUSION: Gross observation showed the defects were filled with cartilaginous tissues in the composite group, and there were no cartilage tissues in the HAAM group, while only fibrous tissues were seen in the blank control group. Histologically, the defect region was full of chondrocytes in the composite group,immunohistochemistry staining indicated that collagen II was rich in the tissue, and furthermore, the cartilage matrix was stained deeply by toluidine blue. In the the HAAM group, there were few chondrocytes, toluidine blue staining was weakly positive, and immunohistochemistry staining was negative, indicating there was no cartilage matrix. In the blank control group, the defects were filled of fibroblasts and toluidine blue staining was weakly positive. To conclude, the BMSCs/HAAM is a good scaffold for BMSCs chondrogenic differentiation to effectively repair articular cartilage defects.

Objective To investigate the effects of different abstinent duration on brain functional network of heroin addicts at resting state.Methods Sixteen heroin addicts during protracted abstinence for 11-13 months (PA12 group) and twenty heroin addicts during protracted abstinence for 5-7 months (PA6 group) were recruited in the resting-state functional MRI study.Graph theoretical methods were applied to construct topological organization of whole brain network and nodes betweenness of the networks in all subjects,and the between-group differences were analyzed.The correlation of the node betweenness with the abstinence duration was conducted.Results There was no significant difference (P>0.05) in the small world characteristic (γ≈1,λ》1) between two groups.Compared with the PA6 group,the PA12 group demonstrated significantly decreased nodal betweenness in regions of left parahippocampal gyrus,left precentral gyrus,and significantly enhanced nodal betweenness in regions of the left cuneus,left temporal and right middle occipital gyrus (all P<0.05).Moreover,the betweenness of the left precentral gyrus (r =-0.52,P =0.001) and parahippocampal gyrus (r=-0.49,P=0.002) were negatively related with the abstinence duration,the betweenness of the right middle occipital was positively correlated with the abstinence duration (r=0.49,P=0.003).Conclusion The brain network small world topology of heroin addicts tend to be stable after 5-7 months of abstinence.Long-term abstinence may minimize the addicfs memory of drugs and potential drug seeking behavior,and recover addicts' visual spatial attention function.

PurposeHeroin addiction is a chronic and recurrent functional brain disease, there are some functional changes in specific brain regions, but the network character remains unclear. The aim of this paper is to explore the network character of brain resting-state functional network in heroin addicts, to identify the potential neuromechanism of heroin addiction from the perspective of brain network.Materials and Methods Thirty heroin addicts (HA group) and twenty-nine healthy controls (control group) underwent resting-state functional MRI scanning using GE 3.0T MRI scanner. The brain functional networks were constructed based on graph theory, the small-world properties and node properties were calculated and compared between the two groups, the correlation between the total dosage of heroin and node degree was analyzed.Results Compared with control group, the small world characteristics of HA group was altered with statistically significant difference (P<0.05, corrected by false discovery rate); the node degrees in orbit frontal regions increased, while those in occipital brain regions decreased (P<0.05, corrected by false discovery rate). No correlation was found in HA group between node degree and the total dosage of heroin.Conclusion These results suggest that topology of functional brain networks were altered in heroin addicts which tends to random networks; increased motivational driving to the salience of drug and decreased visuospatial attention in heroin addicts may provide a strategy for identifying the neuromechanism of heroin addiction.

Objectives To summarize the clinical characteristics of imported falciparum malaria patients and the treatment so as to provide the evidences for improving the diagnosis and treatment of the disease. Methods A total of 138 imported falci?parum malaria patients who received the treatment in Shandong Institute of Parasitic Diseases from January 2007 to February 2013 were adopted as the observation subjects and their clinical data were collected and analyzed. Results All the 138 pa?tients were back from African countries. The main manifestations were fever headache asthenia and hepatosplenomegaly and most of them were with decreased RBC PLT levels and increased LDH levels and 36.96%of them were misdiagnosed as respiratory diseases nephritis hepatitis and so on. Through antimalarial treatment of artemether or artesunate or dihydroartemis?inin and primaquine or dihydroartemisinin and piperaquine and symptomatic treatment the short?term and long?term cure rates were 98.55%and 94.93%respectively with 1 case unrecovered and 1 died. Conclusions Artemisinins are still the most effective antimalarial drugs for falciparum malaria. However some patients recrudesce as the Plasmodium in their body is resis?tant or insensitive to these drugs. We should pay more attention to the antimalarial and symptomatic treatments in the early stage of severe malaria so as to improve the cure rate.

Objective To evaluate the effectiveness of the treatment of high risk benign prostatic hyperplasia (BPH) with transrectal high-intensity focused ultrasound (TR-HIFU) by urodynamic test. Methods One hundred and thirty patients with BPH, most of who suffering with diabetes mellitus,cardio-cerebrovascular disease, respiratory disease. All patients were given the operation with Sonablate-500 high-intensity focused ultrasound (HIFU). International prostate symptom score (IPSS), quality of life (QOL), maximum urinary flow rate (Qmax), post void residual urine volume (PVR), pressure-flow tests (A-G) were employed for the evaluation of curatives effect on preoperation, 30th and 90th day after the treatment. Results The duration of the TR-HIFU prostate ablation treatment was 15-85 rain. One hundred and seven patients after treatment were followed up for 3 months. Compared the effect before treatment with that after treatment, IPSS improved from (27.0 ±11.5) scores to (8.5±1.4) scores, Qmax increased from (5.7±2.3) ml/s to (14.1±4.2) ml/s, PVR decreased from (118.5±78.0) ml to (30.0±15.0) mI,A-G parameters reduced from 62.4±19.3 to 25.6±13.0 and urine volume (VV) increased from (85.8 + 42.0) ml to (194.0±52.0) ml. The parameters all altered obviously (P < 0.05). Conclusions TR-HIFU appears highly attractive as a new optional, safe and efficacious and minimally invasive treatment for the high risk BPH. Main post-operative urodynamie parameters are more obviously improved than those of the preoperation.

Objective To evaluate the feasibility of assessing osteoarthritis (OA) in hip dysplasia using 3D delayed gadolinium-enhanced MRI of cartilage (dGEMRIC).Methods Thirty-five hips in 20 patients with radiographic evidence of hip dysplasia underwent 3D-dGEMRIC scanning.Clinical symptoms were assessed with the Western Ontario and McMaster Universities Osteoarthritis ( WOMAC ) questionnaire.Radiographic measurement of lateral center-edge angle and T(o)nnis grading were performed on the X-rays.Hips of T(o)nnis grade 1were included in the group of hips with early OA,while the hips with no evidence of OA and without pain symptom were included in the group of hips with normal morphology.The 3D-dGEMRC scans were completed on a 1.5 T MR scanner.The data of 3D-dGEMRIC was reconstructed radically.The dGEMRIC indices were measured on six sites of periphery zones of hip cartilage on reconstructed images.The dGEMRIC indices among different groups were analyzed by non-parametric tests.The differences of dGEMRIC indices among six sites in the group of early OA or the group of normal morphology were analyzed by Wilcoxon test.Results The mean dGEMRIC indices of six sites were lower in group of T(o)nnis grade 1than in group of T(o)nnis grade 0 ( Z =- 2.149,P =0.032 ),and lower in group of T(o)nnis grade 2 than in group of T(o)nnis grade 1( Z =- 1.990,P =0.047 ).The dGEMRIC indices of the anterior site,anterosuperior site,superior-anterior site,and superior site were significantly different between the group of hips with early OA and the group of hips with normal morphology (Z =-2.333--2.041,all of the P values were lower than 0.05).In the group of hips with normal morphology,the dGEMRIC indices of superior-anterior site of hip were lower than superior site(P =0.028).In the group of hips with early OA,the dGEMRIC indices of superior-anterior site were lower than the other sites except for anterior-superior site ( Z =- 3.041- - 2.277,all of the P values were lower than 0.05 ).Conclusions 3 D-dGEMRIC might be a sensitive technique for detection of glycosaminoglycans alteration in early OA and staging of OA in hip dysplasia.Radial reconstruction could provide an accurate assessment of OA,and the results demonstrated that early cartilage alteration could be detected in the anterior to superior sites of hips,and the earliest cartilage alteration may occur in the superior-anterior site of hips.
