ABSTRACT
Objective To investigate the MRI findings of displaced bucket-handle tear in medial meniscus. Methods From April 2011 to August 2015 in our hospital, the clinic and MRI data of 12 patients with displaced bucket-handle tear in medial meniscus confirmed by arthroscopy were retrospectively analyzed. Results 12 cases were unilateral. Fragment shift sign, double posterior cruciate ligament sign, flipped meniscus sign and double meniscus forefoot sign, abnormal circumferential meniscus sign, bow tie broken sign and disproportional posterior horn sign could be seen in all cases. Conclusion Displaced bucket-handle tear in medial meniscus has some characteristic manifestations on MRI, MRI can be used as a preferred imaging methods for displaced bucket-handle tear in medial meniscus.
ABSTRACT
Objective To investigate the diagnostic value of MRI in chronic completely tear of the anterior cruciate lig-ament(ACL). Methods From January 2013 to September 2015 in our hospital,the clinic and MRI data of 20 cases with chronic completely tear of the ACL proved by arthroscopy. Results The diagnostic accuracy rate of MRI was 75%(15/20), and 25%(5/20) was misdiagnosed as partial tear.The MRI signs were: ACL ligament direction (n=20, 100%), abnormal ACL increased signal (14 cases, 70%), tibia forward (n=19, 95%), abnormal deeper lateral femoral notch or bone contusion or cartilage erosion(n=20, 100%), smaller bending angle index of posterior cruciate ligament(n=20, 100%), with the medial meniscus injury(n=18, 90%). MRI also clearly showed other lesions in the knee joint. Conclu-sion MRI has high diagnostic accuracy in chronic completely tear of the ACL, so which is worthy of application.
ABSTRACT
Objective To evaluate the effect of finasteride on perioperative bleeding following transurethral plasmakinetic resection of prostate (PKRP).Methods A total of 118 patients with benign prostatic hyperplasia (BPH) undergoing PKRP were randomly divided into three groups:40cases received 5mg of finasteride daily for 7 days before surgery as 1 week group,38 cases received 5mg of finasteride daily for 3 months before surgery as 3 months group,the other 40 cases without taking finasteride before surgery as control group.A comparative study of clinical data was made among the three groups.Results The operation was successfully completed in 118 cases.As compared to control group,intraoperative irrigating fluid volume[(31.5 ± 5.6) L vs.(26.4 ± 6.2) L and (24.3±5.2)L],intraoperative blood loss[(173.5± 16.9) ml vs.(163.5± 15.8) ml and (156.4±16.2) ml],loss of 1 gram prostate tissue for resection[(8.6±4.8)ml/g vs.(7.4±5.4) ml/g and (6.6±5.6) ml/g]and operation time(72.5±16.2) min vs.(58.4±17.8) min and (56.7±16.5) min in 1 week and 3 months groups with taking finasteride were decreased (all P＜0.05).And there were differences in the above indexes (all P＜ 0.05) between 1 week group and 3 months groups.Conclusions The use of finasteride before PKRP is safe and reliable to reduce perioperative bleeding in BPH patients.Moreover,taking 5mg of finasteride for three months is of better effectiveness than taking 5mg of finasteride for 1 week.
ABSTRACT
Objective To explore the expression of Tiaml in clear cell renal cell carcinoma and analyze its correlations to pathology of disease and prognosis.Methods The expressions of Tiam1 protein in 107 specimens of human clear cell renal cell carcinoma and 20 specimens of normal renal tissues were detected by immunohistochemical staining and its clinical significance was then analyzed.Results The expression of Tiam1 protein was higher in renal cancers than in the adjacent normal tissues ( P ＜ 0.01 ).Tiam1 protein expression rates were 47.6％ and 72.7％ in Ⅰ - Ⅱ and Ⅲ - Ⅳ tumors,while 49.3％ and 76.5％ in T1 - T2 and T3 - T4 tumors,respectively ( P ＜ 0.01 ).Expression of Tiam1 protein was higher in lymph node positive renal carcinoma tissues than in lymph node negative renal carcinoma tissues ( 71.7％ versus 47.5％,P ＜ 0.05 ).The expression of Tiam1 in carcinoma tissues showed a positive relationship with tumor vascular invasion (81.3％ versus 48.0％,P ＜ 0.01 ).In patients followed-up 5 - 8 years,Kaplan-meier analysis and the log-rank test showed that the 5-year survival was significantly different between the group of lower and higher Tiaml expression groups ( 84.4％ versus 46.8％,P ＜ 0.05 ).Conclusions The expression of Tiaml protein was higher in human primary renal carcinoma than in normal renal tissues.The positive rate of Tiam1 protein expression was related to classification,TNM stage,lymph node metastasis and vascular invasion.The detection of the expression of Tiaml protein may be helpful in the diagnosis and prognosis of renal carcinoma.
ABSTRACT
Objective To study the diagnosis and treament of adrenal cortex and medulla hyperplasia. Methods The clinical data of 3 cases of adrenal cortex and medulla hyperplasia were analysed.All the 3 patients had hypertention and elevation of VMA and 1 had hypokalemia.Abnormal CT manifestations have been observed in all. Results Left adrenectomy or subtotal adrenectomy is done for the patients.1 patient recurred 6 months later and was cured by total adrenectomy on the right side. Conclusions Adrenal cortex hyperplasia could be secondary to medullary hyperplasia.When medulla hyperplasia is properly managed,cortex hyperplasia may automatically subside.
