Objective To study the clinical manifestations and surgical treatment in renal transplant recipients with benign prostatic hyperplasia (BPH). Methods From January 2013 to May 2015, 5 patients of kidney transplant recipients who suffered from BPH for transurethral resection of prostate (TURP) treatments were enrolled (kidney transplant recipients group) and 15 patients with the same surgical treatments during the same peoriod were enrolled too (common control group). The routine examination, urodynamic, sex hormone levels and and the clinical efficacy were observed. Results The levels of hemoglobin, total protein, urea nitrogen, creatinine, prostate volume , residual urine and maximum flow rate (Qmax) before operation between two groups had no significant differences (P>0.05). The level of testosterone in kidney transplant recipients group was significantly lower than that in common control group: (3.5 ± 1.2) mmol/L vs. (5.5 ± 2.2) mmol/L, P < 0.05. The level of estradiol in kidney transplant recipients group was significantly higher than that in common control group:(49.6 ± 13.8) mmol/L vs. (40.5 ± 16.4) mmol/L, P < 0.05. In kidney transplant recipients group, the levels of hemoglobin, total protein, urea nitrogen, creatinine before and after operation had no significant differences (P>0.05). After operation, the levels of hemoglobin, total protein, urea nitrogen, creatinine in two groups had no significant differences (P>0.05). In kidney transplant recipients group, the quality of life (QOL) score before operation was 5 scores in 4 cases and 6 scores in 1 case, and those after operation were zero in 3 cases and 1 score in 2 cases. Conclusions Under the sufficient preoperative preparation and assessment, the renal transplant recipients with BPH patients can improve the symptoms of urinary obstruction and obtain satisfactory clinical efficacy as common BPH patients.

Objective To evaluate the value of real time three-dimensional ultrasound in differentiating benign and malignant breast tumors. Methods One hundred and fifty-three patients with breast tumors were examined with real time three-dimensional ultrasound. The results were compared with post-operative pathological results. Results A sign of malignancy on the coronal plane was observed by three-dimensional ultrasonography,named “sun-like symptom”,because the sign looked like a shining sun:striated hyperechoic or iso-echoic images scattered radially around cancers,together with the distortion of normal tissue.The accuracy of the sign in differentiating benign and malignant breast tumors was 86.93 %( 133/153 ), the sensitivity was 78.38 %( 58/74 ), and the specificity was 94.94 %( 75/79 ). Conclusions Real time three-dimensional ultrasound is a valuable and new technique in differentiating benign and malignant breast tumors.

Objective To assess the application of Xpert MTB/RIF assay in rapid diagnosis of tuberculous lymphadenitis.Methods Lymph node samples were collected from 1 02 clinically diagnosed patients with lymph node tuberculosis and 65 patients with other lymph node diseases from Zhejiang Provincial Hospital of Traditional Chinese and Western Medicine during January 201 4 and February 201 5. Xpert MTB/RIF,pathological examination and mycobacterium tuberculosis culture were conducted in all specimens of two groups.Taking clinical comprehensive diagnosis as the gold standard,the diagnostic sensitivity,specificity,positive predictive value,negative predictive value and diagnosis efficacy of three detection methods were assessed.The sensitivity of Xpert MTB/RIF in determining rifampicin resistance was analyzed using drug susceptibility testing as gold standard.Results The mean detection time of Xpert MTB/RIF was (2.2 ±0.2)h.Among 1 02 patients,Xpert MTB/RIF achieved higher sensitivity (96.1 %, 98 /1 02 ) than pathological examination (76.5%,78 /1 02 ) and mycobacterium tuberculosis culture (33.3%,34 /1 02)(χ2 =1 6.558 and 87.91 9,both P <0.01 ).Among 65 patients with other lymph node diseases,the specificity of all three detection methods was 1 00%.The receiver-operating-characteristic curve analysis demonstrated that diagnostic performance of Xpert MTB/RIF was better than that of other two methods.In 8 patients resistant to rifampicin confirmed by drug susceptibility testing,Xpert MTB/RIF detected 6 resistant-resistant patients.Conclusion Xpert MTB/RIF shows higher sensitivity and specificity in diagnosis of lymph node tuberculosis with the advantages of easy and rapid performance.

Objective To depermine if a double mainpenance dose of clopidogrel can improve phe clinical oupcome in papienps who have clopidogrel htpo-responsiveness ( CH) afper percupaneous coronart inpervenpion (PCI) and analtze correlapive risk facpors of CH. Methods We had enrolled 134 consecupive papienps undergoing PCI for spable coronart arpert disease in our cenper bepween Januart 2014 po June 2015. CH was depermined bt plapelep aggregapion measured bt phrombelaspographt ( TEG). Blood samples were paken 24 h and 3 monphs afper PCI procedure. All subjecps were divided inpo 2 groups (i. e phe CH group and phe clopidogral sensipive group) according po pheir responsiveness bt TEG. The CH group (n = 45) received a double mainpenance dose of clopidogrel as 150 mg/ d and phe clopidogrel sensipive group (n = 89) received a spandard mainpenance dose as 75 mg/ d. Changes in clopidogrel responsiveness and correlapive risk facpors were observed afper 3 monphs of clopidogrel preapmenp. Major adverse cardiac evenps (MACEs) and bleeding incidenps were recorded during follow-up lease 6 monphs. Results The clopidoprel htpo-responsive rape decreased from 33. 6% (45 / 134 papienps) po 11. 9% (16 / 134 papienps) afper 3 monphs of preapmenp. No spapispical difference found bepween phe 2 groups in morpalipt rape and non-fapal mtocardial infarcpion ( P >0. 05). Rapes of overall MACE (33. 3% vs. 22. 5% ), rehospipalizapion (26. 7% vs. 16. 9% ) and pargep vessel revascularizapion (11. 1% vs. 6. 7% ) were significanp higher in phe CH group ( all P < 0. 05) . Mulpivariape regression analtsis showed: smoking ( OR 4. 498, 95% CI 1. 378 - 4. 018, P = 0. 036), diabepes (OR 4. 385, 95% CI 1. 370 - 7. 552,P = 0. 026) and clopidogrel dosage ( OR 0. 597, 95% CI 1. 005 - 2. 676, P = 0. 019 ) were phe risk facpors for CH. Conclusions For papienp wiph htpo-responsiveness po clopidogrel afper PCI, a higher mainpenance dose of clopidogrel as 150 mg/ d for 3 monphs can provide equivalenp clinical benefip in serious adverse evenp (including morpalipt and non-fapal mtocardial infarcpion) compared po spandard mainpenance dose for clopidogrel responsive papienps.
