OBJECTIVETo report a case of simple congenital bilateral ejaculatory duct absence (EDA) complicated with seminal vesicle cyst and review the relevant literature in order to improve the diagnosis and treatment of the disease.

METHODSWe retrospectively reviewed the clinical data of a case of bilateral congenital EDA complicated with seminal vesicle cyst, reviewed the relevant literature at home and abroad, and comprehensively analyzed the embryonic development, diagnosis, and treatment of congenital EDA.

RESULTSThe patient was a 23-year-old man, present at the clinic for infertility after married for a year. Vasography and other imaging examinations confirmed simple congenital bilateral EDA complicated with seminal vesicle cyst. Pathologic biopsy showed normal spermatogenic function of the testes.

CONCLUSIONCongenital EDA originates from embryonic developmental defect of the mesonephric duct, and it can be confirmed by vasography. Transurethral incision of the ejaculatory duct and intracytoplasmic sperm injection can be employed for the treatment of bilateral EDA.

Objective To analyze the changes of serum total bilirubin (TBil) and gamma glutamyltransferase (GGT) in patients with type 2 diabetes newly diagnosed without complications and explore their relationship with vascular complications of type 2 diabetes.Methods The levels of serum TBil and GGT were determined by automatic biochemical analyzer in 42 healthy person (control group),64patients with type 2 diabetes without complications (diabetes without complications group) and 81 patients with type 2 diabetes with vascular complications (diabetes with complications group).Results The levels of serum TBil and GGT were (7.89 ± 4.81) μ mol/L and (29.81 ± 14.97) U/L in diabetes with complications group.The level of serum TBil was (10.42 ± 3.55) μ mol/L in control group.The levels of serum TBil and GGT were (11.30 ± 4.16) μ mol/L and (47.00 ± 38.57) U/L in diabetes without complications group.The level of serum TBil in diabetes with complications group was lower than that in control group and diabetes without complications group (P ＜ 0.05).The level of serum GGT in diabetes with complications group was lower than that in diabetes without complications group (P ＜ 0.05).Pearson correlation analysis showed that 24-hour urinary protein excretion,urinary albumin creatinine ratio had negative correlation with serum TBil (P ＜0.05).Logistic regression analysis showed that GGT was the protective factor of diabetic vascular complications (OR =0.965).Conclusion The levels of serum TBil and GGT may be associated with the occurrence and development of vascular lesions in patients with type 2 diabetes.

Acetabulum fracture, the inner fracture of the joint, has be en divided into 10 kinds. Because acetabulum is an irregular body, no single ope ration approach can solve all kinds of acetabular fracture. Appropriate selectio n of the operative approach according to the type of fracture is very important. Kocher-Langenbeck approach, extended-iliofemoral approach and ilioinguinal ap proach are often used in clinic now. Because of its complicated procedures and m any complications resulting from the approach, the application of extended-ilio femoral approach is decreasing. Because of its predominant advantage and improve ment of the operation techniques, the use of ilioinguinal approach is obviously increasing in proportion. Since the united approach can reveal clearly so that i t facilitates reduction and internal fixation, it is recommended by the surgeons at home and abroad.

Objective To establish a rabbit model of facial skin lifting and to evaluate the skin lifting effects of absorbable soft tissue plastic belt, and to provide experimental basis for clinical application of this plastic belt.Methods 36 Japanese white rabbits were randomly divided into model control group (n=6) and plastic belt lifting group (n=30). The model control group received only facial skin resection surgery, while the plastic belt lifting group had facial skin resection and plastic belt implantation.The changes of rabbit general status, skin lifting effects, performance of plastic belt and pathological changes of subcutaneous tissue after implantation were determined during the 4 weeks after surgery. Results The rabbit skin wound was healed within 3-7 days after surgery without infection.Meanwhile, the plastic belts did not show shifting or rupture, and only whitening around the perforations was observed in the two groups.Compared with the model control group, the MA and MB distances in the plastic belt lifting group were significantly lower ( P<0.01 ) , while the biological tension of plastic belts in the facial skin lifting rabbit models was significantly increased with the extension of time after implantation (P<0.01), and the biological tension was 18.62 N at 4 weeks after transplantation. In addition, the tensile intensities of perforations and plate in the two groups were significantly reduced at 4 weeks postoperatively (P<0.01), the tensile intensity of perforations and plate in the two groups were maintained at 35.07 N and 53.31 N, respectively, and the perforations/plate tensile intensity ratio of the two groups remained unchanged during 4 weeks after transplantation ( P >0.05 ) .Moreover, the molecular weight ( Mw ) , peak molecular weight ( Mp ) , Z molecular weight (Mz) and viscosity were gradually decreased along with the time passing after implantation (P<0.01), and its dispersion Mz/Mw ratio was also gradually decreased from 2 weeks after implantation (P<0.01), and no obvious pathological changes were found after subcutaneous implantation of the plastic belts.Conclusions We have successfully established a facial skin lifting rabbit model, and the plastic belt can obviously lift the facial skin fascia system and keep intact more than 4 weeks in the body.Therefore, this plastic belt can be applied for anti-wrinkle facial soft tissue lifting against the skin damage caused by aging.

OBJECTIVETo identify the correlation of the volume of residual urine (VRU) with the severity of bladder outlet obstruction (BOO) and detrusor contractility in patients with benign prostatic hyperplasia (BPH).

METHODSA total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and urodynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20. 0, we analyzed the correlation between the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test.

RESULTSThe prostate volume was correlated positively with BOO severity (r = 0.432, P < 0.01) and detrusor contractility (r = 0.343 , P < 0.01) while Qmax negatively with BOO severity (r = 0.327, P < 0.01) but not significantly with detrusor contractility (r = 0.123, P > 0.05). VRU showed a significantly negative correlation with detrusor contractility when > 150 ml (r = -0.490, P < 0.01), even more significantly when > 300 ml (r = -0.717, P < 0.01), but exhibited no significant correlation with it when ≤ 150 ml (r = 0.041, P > 0.05).

CONCLUSIONVRU can somehow predict the detrusor function. For patients with VRU > 150 ml, especially for those with VRU > 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.

OBJECTIVETo investigate diagnosis and therapeutic effects of knee joint synovial chondromatosis with arthroscopic.

METHODSFrom March 1995 to July 2011, 28 patients with knee joint synovial chondromatosis were treated. Among them, 18 males and 10 females ranging age from 25 to 81 (mean 55.2) years,the course of disease ranged from 0.5 to 15 (mean 5.6) years. Clinical manifestation mainly included pain, swell and functional limitation of knee joint. Knee open surgery (17 cases) and laparoscopic surgery (10 cases) were respectively used. Clinical symptom,image data,pathological manifestation and effects under arthroscopy were observed, Lysholm scoring was used to evaluate effects.

RESULTSAll patients were followed up except one lost, the duration ranging from 6 to 24 months. Lysholm score in knee open surgery was increased from (41.89 +/- 6.81) preoperatively to (67.73 +/- 7.62) postoperatively;while in laparoscopic surgery it was increased from (40.78 +/- 7.54) preoperatively to (77.46 +/- 8.43) postoperatively.

CONCLUSIONArthroscopic surgery, which has no risk of rupture of incision, nonunion, earlier to exercise, is a good method to diagnosis and treat knee joint synovial chondromatosis.
