Objective The purpose of this study was to evaluate computed tomography urography (CTU) and compared with conventional intravenous urography (IVU) in diagnosis of urological disease. Methods One hundred and sixty-five patients with 111 males and 54 females underwent CTU urography including 78 cases underwent IVU were reviewed in this study. There were 12 cases underwent retrograde pyelography. There were 75 cases of nephrolithiasis and ureterolithiasis, 30 cases of ureteropelvic junction obstruction (UPJO), 30 cases of bladder cancer, 15 cases of pyelogenic cyst and parapelvic cyst, 9 cases of megaloureter and 6 cases of cancer in pelvis and ureter. Results The accuracy of diagnosis was 94.5% (156/165) in CTU group and 46.7% (42/90) in IVU group.The accuracy of diagnosis was 100.0% (75/75)of nephrolithiasis and ureterolith in CTU group and 78. 6%(33/42)in IVU group, 90.0% (27/30) of UPJO in CTU group, 100.0% (30/30) of bladder cancer in CTU group and 75.0%(9/12)in IVU group, 80.0%(12/15)of pyelogenic cyst and parapelvic cyst in CTU group, 100.0% (9/9)of megaloureter in CTU group, 100.0% (6/6)of cancer in pelvis and ureter in CT group. The displayed rate of the distal end of stenosis and obstruction was 79.4%(81/102)in CTU group and 25.0%(15/60)in IVU group. The examination time was (18.9±8.4)min in CTU group and (67.1±26.7)min in IVU group. Conclusion The CTU can provide more information than conventional IVU and can replace the IVU as routine examination in most cases.

Objective To determine the change in expression of detrusor myosin heavy chain isoforms,SM1 and SM2,following bladder outlet obstruction (BOO) in rabbits. Methods Fourteen New Zealand white male rabbits were divided into 2 groups:control group (n=7) and obstruction group (n=7).The bladder necks were partially ligated to form BOO animal model in obstruction group.Then 5 weeks after operation the bladders were resected in both groups, and the weight and volume of the bladders were measured. After the detrusor tissue protein was extracted,SM1,SM2 and their mRNA were tested by western blotting and RT-PCR methods. Results The bladder weights of obstruction and control groups were (13.8?4.4) g and (3.7?0.5) g, respectively (P

Liquichip is a new type of biochip emerging in the 1990s, which is integrated flow cytometry, laser technology, digital signal processing and traditional chemical technology with the greatest features of high-throughput and high-flexibility. Luminex has promoted new products from Luminex 100/200 to Flexmap 3D. This is an introduction to the development, principle, and application of Luminex liquichip.

Radiotherapy is the main treatment method of early lung cancer not undergoing surgery for medical reasons and advanced non-resectable lung cancer. The local regional control of lung cancer requires high-dose irradiation, but this treatment is restricted by normal tissue tolerance. The measurement and control of errors are crucial for safe implementation of lung cancer precision radiotherapy. Lung tumor radiotherapy error sources, the methods to control these errors, and the error development trend are discussed in this review.

Induced pluripotent stem cells (iPSCs) are a type of pluripotent stem cells that can be generated from adult somatic cells.They have similar characteristics and function to embryonic stem cells (ESCs).Over the past decade,iPSCs were widely concerned in regenerative medicine and stem cell field.Especially the patient specific iPSCs have several advantages over ESCs,such as convenient source,do not exist immune rejection and ethical issues,even keep certain individual genotype.At present,tremendous progress have been made about the application of iPSCs in a variety of retinal diseases.Here,this article reviews pluripotent stem cell sources of RPE,photoreceptors and retinal ganglion cells and current transplantation strategies,the safety problems and prospects.

Construction of teacher's professional morality is a major issue that matters the development of both teachers themselves and medical colleges,especially under the current circumstances of constructing a harmonious society.This article summarizes the phenomenon of absence in teacher's professional morality in market-oriented economy,elaborates theoretically the necessity of strengthening teacher's professional morality construction in medical colleges,and proposes briefly strategies to strengthen the construction of teacher's professional morality.

Objective To report our experience of nephron sparing surgery (NSS) with mini-incision approach.Methods Sixty-one mini-incision NSS were analyzed retrospectively from 2005 to 2011 in our department.Demographic and clinical data,complications,histologic and oncologic data were analyzed.There were 35 males and 26 females with average age of 41 years.B ultrasound and CT scan were performed in all cases and MR was performed in 23 cases.CT angiography was performed in 10 cases.Renal cell cancer was diagnosed in 38 cases,angiomyolipoma in 14 cases,complicated renal cyst or duplicated kidney in 6 cases and no definite diagnosis in 3 cases.All the lesions were single with 21 in the right side and 40 in the left side.The average diameter of the lesions was 3.2 (2.3-8.8) cm.The mini-flank supra-12th rib incision was performed in all cases.The renal artery was clamped with bulldog clamp,all transected blood vessels on the renal incisal surface were sutured with 3-0 Vicryl sutures,and collecting system was closed with continuous' 3-0 Vicryl suture.Results The average length of incision was 8.1 (6.5-11.0) cm.The average operative time was 93 (70-140) min.The average warm ischemia time was 19 (12-32) min.The average blood loss was 72 (20-300) ml and the average hospital stay was 6 (5-15) d.The delayed hemorrhage was occurred in 1 patient who was treated with conservative treatment.Clear cell carcinoma was found in 28 cases,chromophobe carcinoma was found in 6 cases,papillary carcinoma was found in 5 cases,angiomyolipoma was found in 16 cases,complicated cyst was found in 3 cases and renal duplication was found in 3 cases.Fortyfive patients were followed up from 28 to 82 months with no delayed complication and no recurrence or metastasis in 35 malignant cases.Conclusions The approach of mini-incision NSS can duplicate the procedure of traditional open NSS.This approach can also couple the benefits of both laparoscopic and open NSS techniques with a smaller incision which can be used to remove the specimen.

To explore the clinical features,diagnosis and treatment of Langerhans cell neoplasms.The data of 6 patients with Langerhans cell neoplasms was analyzed retrospectively.There were Langerhans cell histiocytosis (LCH,n =5) and Langerhans cell sarcoma ( LCS,n =1 ).Among 5 LCH patients,the involved organs included waist,back,scalp,inguinal lymph nodes,parotid gland and left femur.And the symptoms were fever,splenohepatomegalia and destruction of bone.Three patients received surgery,1 had radiotherapy and 1 was discharged without treatment.The follow-up period was 34 - 138 months.Two patients had no relapse,the contra-lateral parotid gland became involved later in another and several organs were involved in other patients.One patient was lost to follow-up.Left occiput of another LCS was involved and both surgery and radiotherapy were administered.Over a follow-up period of 41 months,there was no relapse.Either surgery or radiotherapy is indicated for this rare disease when a single organ is involved.And chemotherapy is administered for the involvement of multiple organs.The patients should be treated individually.
