Objective To access the ability of MRI for detecting the radial meniscal tears.Methods Arthroscopy of the knee was performed by a single orthopedic surgeon on 1085 patients. On the basis of the results of arthroscopy, 107(9.9%) knees had radial tears of menisci. Through interval sampling of the patients with meniscal tears but not radial tears, 100 patients were selected as a controlled group. All MR images were analyzed by two radiologists independently. Four radiological signs were used to detect radial tears: cleft and marching cleft sign, detached sign, ghost sign, and small meniscal sign. All the features of MRI were compared with the results of the arthroscopy. Results (1) The most frequent location of radial tears was the midbody of lateral meniscus (71/107, 66. 4%)followed by the boundary of anterior horn and midbody of the lateral meniscus (25/107, 23.4%). (2) One hundred and two of 107 patients were identified as radial tears on MRI. However, 11 of 100 patients with non-radial tears were misdiagnosed as radial tears by MRI. The sensitivity, specificity, positive predictive value, and negative predictive value of MRI were 95.3% (102/107),89.0% (89/100),90.3% (102/113), and 94.7% (89/94),respectively. (3) The cleft sign (59/102, 57.8%) and detached sign (43/102, 42.2%) were the most frequent and important MRI signs. Conclusion The accuracy of MRI to identify the radial meniseal tears'is very high and MRI is the best imaging modality for patients suspected of radial meniscal tears.

Objective The purpose of this article was to investigate the internal tunnel position during anterior cruciate ligament (ACL) reconstruction with single-bundle ACL. Methods MRI were performed in 10 knees form 10 volunteers at full extension and at 30°, 60°, 90°, and 120° flexion position. All the images obtained were exported into Mimics 10.01. Three-dimensional models were established with Mimics in a computer. All the mark points were confirmed on femur and tibia. The distance between the femoral mark point and tibial mark point was measured. The isometric point was determined as the change in the distance was shorter than 3mm during knee flexion-extension. Results Ten three-dimensional models were established successfully and the isometric points of A0-X, A15-X, A30-X, A45-X, B0-Y, B15-Y, B30-Y, B45-Y, C0-Z, C15-Z, C30-Z, C45-Z, and C60-Z were identified. Conclusion There was no absolute anatomical isometric point, whereas the physiological isometric point did exist. Therefore, determination of tibial point should be considered synthetically. B45-Y was recommended for tunnel position.

ObjectiveTo explore the effect of metabolic syndrome (MS) on the occurrence and development of benign prostate hyperplasia (BPH).Methods 101 elderly BPH patients were divided into two groups:BPH (n = 45) and BPH with MS (n= 56)group.The effects of metabolic indexes,including body mass index (BMI),waist,high density lipoprotein cholesterol (HDL-C),fasting blood glucose (FBS) and insuline resistance index (H()MA-IR),on prostate volume(PV),prostate-specific antigen (PSA),international prostate symptom score (IPSS) and lower urinary tract symptoms (LUTS) were surveyed in BPH patients.Results BPH with MS group showed significantly higher values of PV (t = 3.22,P= 0.003)and longer course of LUTS (t= 2.02,P =0.046) than BPH group.The BPH patients with overweight and obesity had significantly higher levels of PV(49.44±26.83 ml and 51.7±22.2 ml,P=0.021 and 0.043) than BPH patients with normal weight (38.10 ± 10.64 ml).Additionally,BPH patients with abdominal obesity had significantly higher levels of PV than BPH patients without abdominal obesity(50.26±26.51 ml vs.38.99± 11.25ml,P=0.005).BPH patients with low HDL-C had significantly higher PV than BPH patients with normal HDL-C[(54.23±28.92)ml vs.(40.40± 14.87) ml,P=0.009].The values of PV,PSA in the BPH patients with elevated FBS were significantly higher than in BPH patients with normal FBS (t=3.17 and 2.4I,P= 0.035 and 0.013).BPH patients with insuline resistance (IR) had higher values of PV and longer courses of LUTS than BPH patients without IR (t= 3.43 and 3.58,P-0.001).The PV was positively correlated with BMI(r= 0.459.P= O.OOO),FINS (r= 0.42,P=O.OOI),HOMA-IR (r= 0.49,P= 0.003) and gatively correlated with HDL-C (r= 0.38,P-0.000)- Multiple linear stepwise regression analysis showed that PV was closely correlated with HOMA-IR.ConclusionsMS has evident effects on the occurrence and development of BPH.

Objective To understand the elementary information and pharmacotherapy for benign prostatic hyperplasia (BPH) in outpatients in geriatrics department of three hospitals. Methods The outpatients diagnosed as BPH were investigated by daily BPH diagnosis report form, BPH medical-care requirement questionnaire, international prostate symptom score (IPSS) questionnaire and BPH quality of life scale (BPHQLS) in odd months. Results There were 657 outpatients in the three hospitals, including 456 males and 201 females. 289 patients were diagnosed as BPH, accounting for 44% of all outpatients and 63.4% of male patients. The average age of BPH patients was (77.2±5.7)years, the mean volume of prostate was (41.44 ± 21.00)ml, the median value of prostate specific antigen (PSA) was 2.24 μg/L, the mean maximum flow rate was (12. 65± 5.74)ml/s, and the average of IPSS and BPHQLS were 14.8±8. 11, 2. 56±1.36, respectively. The percentage of pharmacotherapy was 66.21% (96/145), and the rates of a-receptor blocker monotherapy and 5α-reduetase inhibitor monotherapy were 6.90% and 8. 97%, respectively. The percentage of drug combination was 26.90%. Conclusions BPH outpatients in geriatrics department of the three hospitals are at high risk, and most of them receive drug therapy. The drug choice is reasonable.

Objective To determine whether rizatriptan has an effect on cortical spreading depression (CSD) and c-Fos expression within periaqueductal grey (PAG) induced by CSD in rats. Methods The experimental SD rats were randomly divided into group A injected with KCl, group B KCl plus rizatriptan and group C NaCL The number and amplitude of CSD were recorded after KCl or NaCl injection. C-Fos positive neurons of different layer were identified by the immunohistochemical technique 2 hours after the first injection of KCl or NaCl. Results There was no CSD in group C. The number of CSD in group A ( 10.70±3.23 ) was significantly more than that in group B (6.10±2.56, t = - 3.528, P < 0.01 ). The amplitude of CSD in group A ( 17.33 (95% CI 11.45--23.11 ) mV) was significantly greater than that in group B (11.82 (95%CI 9.24--14.70) mV, Z= -4.360, P< 0.01). There were more cFos-like immnoreactive neurons in every layer in group A than in group C (P < 0.01 ) and in group B (P < 0.05 ). Conclusion Rizatriptan has an inhibitory effect on CSD, which might induce the headache through exciting the neurons in PAG.

Objective: To observe the activation of microglia and the changing rule of inflammatory cytokine as IL-6, IL-10 and nuclear factor-κB (NF-κB) in experimental rabbits after spinal cord ischemia reperfusion (SCIR) injury in order to provide theoretical basis for post-conditioning time. Methods: Rabbit SCIR injury model was established by thoracic aorta balloon occlusion. 54 New Zealand male adult white rabbits were divided into 9 groups: Sham group (the animals received balloon implantation without occlusion), SCIR-0h group (reperfusion was conducted at 0 hour of spinal cord ischemia), SCIR-1h, -2h, -3h, -8h, -24h,-48h and -72h groups. n=6 in each group. The number of normal and apoptosis neurons, the levels of Iba-1, IL-6, IL-10 and NF-κB in spinal tissue were examined and compared among different groups respectively. Results: The number of normal neuron was decreasing with the extended reperfusion time, TUNEL-positive neuron began to increasing in SCIR-8h group and the peak was reached in SCIR-24h group. The expression of Iba-1 began to elevating in SCIR-2h group and the peak was obtained in SCIR-8h group; NF-κB began to rising in SCIR-3h group and the peak was observed in SCIR-8h group; both IL-6 and IL-10 arrived the peak in SCIR-24h group. The expressions of NF-κB, IL-6 and IL-10 were positively related to Iba-1 level. Conclusion: Microglia activation had dynamic changes in experimental SCIR rabbits and the expression levels of NF-κB, IL-6 and IL-10 were positively to microglia activation; post-conditioning time at front and back to microglia activation may reduce neuron injury.
