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.

ObjectiveTo explore the effect of different properties and hemisphere of stroke on trunk control ability and the relationships between the trunk control and cognition, activities of daily living (ADL).Methods75 inpatient stroke patients were divided into the group A (right hemorrhages, n=15), group B (right infarcts, n=25), group C (left hemorrhages, n=14) and group D (left infarcts, n=21). All cases in four groups were assessed by Mini-Mental Status Examination (MMSE), Sheikh Trunk Control Evaluation and Modified Brathel Index (MBI) before and after rehabilitation therapy.ResultsThe scores of Sheikh and MBI of the group A and group C were significantly lower than that of the group B and group D before treatment ( P<0.05～0.001). After treatment, the scores of MMSE, Sheikh Trunk Control Evaluation and MBI of the patients in four groups all increased, but the scores of the patients in the group A and group C increased more than other groups. There was no significant difference in Sheikh scores between right and left hemisphere stroke. All groups had high relationship between Sheikh Trunk Control Evaluation and MBI before and after treatment. There was no relationship between Sheikh Trunk Control Evaluation and MMSE before treatment, but having part relationship after treatment.ConclusionThe trunk control of hemorrhage patients are damaged more severe than that of the infarct cases, but they resume also faster. There are no different between right and left hemisphere stroke in trunk control impairment. The ability of trunk control has high relationship with ADL before and after treatment, it has no relationship with cognize before treatment but has relationship after treatment.

Objective To observe the effect of polyethylene terephthalates (PET) coated with 58S bioactive glass on graft-bone healing.Methods The PET coated with 58S bioactive glass was used in experimental group,and uncoated PET was used as a control.The coating solution was made of 20％ bioactive glass powder and 80％ gelatin powder (by weight).In our vitro study,4×104/ml MT3T3-E1 cells were cultured in 24-well plates with the coated or uncoated PET,and the MTT and ALP were tested at 1,3,5 days to show the proliferation and the activity of the cells.The SEM and the X-ray photoelectron spectrometer were adopted to analyze the surface characteristics of the fiber.In our vivo study,24 skeletally mature New Zealand white rabbits were randomly divided into two groups,the 58S-PET group and the PET group.Both groups underwent a surgical procedure to establish a tibia-articular tendon-bone healing model.Mechanical examination and histological assay were taken to verify the coating effect in vivo.Results The 58S-PET group showed significantly differences in both the MTT and ALP tests at each time point (3,5 days) compared with the PET group.In the animal experiments,the maximum load increased by time in both groups.At 6 weeks,the load-to-failure was significantly higher in the 58S-PET group [(61.70±6.95) N]than that of the PET group [(45.21±9.78) N].At 12 weeks,the load-to-failure was also significantly higher in the 58S-PET group [(89.25±9.50) N]than that of the PET group [(71.38±6.26) N].In the histological assay,it was found that there was new bone formation in the indistinct interface between the graft and the host bone in both groups at 6,12 weeks,and a stronger binding was seen in the 58S-PET group than in the PET group.Conclusion The 58S-PET could enhance the proliferation and activity of the osteoblast and therefore promote the new bone formation and subsequently leads to a positive effect on tendon-bone healing.

The G protein-coupled estrogen receptor (GPER), also known as G protein-coupled receptor 30 (GPR30), was identified in the recent years as a functional membrane receptor different from the classical nuclear estrogen receptors. This receptor is widely expressed in the cortex, cerebellum, hippocampus, heart, lung, liver, skeletal muscle, and the urogenital system. It is responsible for the mediation of nongenomic effects associated with estrogen and its derivatives, participating in the physiological activities of the body. The present study reviews the molecular structure, subcellular localization, signaling pathways, distribution, and function of GPER in the male reproductive system.

0.05).Immunohistochemical staining for intratumoral aromatase in endometrial cancer was positive,21(42 %)in stromal cells.The expression of P450 aromatase in stromal cells correlated positively with advanced surgical stage and histologic grade,indepedent on muscular invasion and lymph node metastasis.Conclusion Aromatase P450 play an important function in establishment and devel- opment of the endometrioid endometrial cancer.The expression of P450 aromatase in intratumoral stromal cells correlated positively with the development and prognosis of endometrioid endometrial cancer.

ObjectiveTo explore the clinical outcomes of posterior lumbar interbody fusion using BTwin expandable spinal spacer with microendoscopic discectomy (MED) for lumbar disc herniation accompanying degenerative instability.MethodsFrom March 2006 to May 2010,87 patients with lumbar disc heniation (only one level) accompanying degenerative instability were managed with posterior lumbar interbody fusion using B-Twin with MED,includeing 49 males and 38 females with an average of 47.6 years(range,37-65).Objective level located in L3,4 in 2 cases,L4,5 in 43,and L5S1 in 41.The patients were treated with single BTwin(Single group,n=51) and double B-Twin(Double group,n=36).Clinical outcomes were evaluated with surgical time,blood loss,visual analogue scale (VAS) scores,Oswestry disability questionnaire (ODI),and the pre- and post-operative disk space heights.ResultsThe patients were followed up for an average of 35.8months (range,12-46).All the patients felt the low back pain and radiation pain disappeared or relieved apparently.The mean preoperative ODI and VAS scores decreased from 78％±3％ to 18％±3％,and (8.70±11.3)to (0.65±10.48) at the final follow-up respectively.Disc space increased from a pre-operative height of (8.76±1.3) mm to a post-operative of (11.8±0.6) mm.ODI,VAS and the disk space heights in all patient showed statistical significance,which revealed no statistical significance between the two groups.However,the operation time,blood loss were statistical difference between the two groups.All the patients achieved solid union or probable union at a mean time of 5.6 months (range,3.9-8.6).ConclusionPosterior lumbar interbody fusion using B-Twin with MED can obtain satisfactory outcomes in the treatment of lumbar disc herniation accompanying degenerative instability.Single B-Twin can get similar clinical outcomes,but shorter surgical time,less blood loss,and less medical costs.
