Objective To explore the clinical character,diagnosis and treatment principals of pyeloureteritis glandularis and cystitis glandularis.Methods The clinical manifestation,character of imageology and endoscopy images of the case for one year follow-up were analyzed and the relevant literatures were reviewed.Results During one year follow-up,there was no clinical symptoms and any progress on imageology.The patient is still in close following-up.Conclusions According to literatures,cystitis glandularis is not common in clinical,and it should be paid more attention by clinicians.There were a few reports about the ureteritis glandularis.Pelvis,ureter and bladder have the same epithelial tissue,pyelitis glandularis is very rare,up to now there is no efficient treatment ways.

Objective To study the effects of ghrelin on action potential (AP) and transient outside K+ current (Ito) in ventricular myocytes of diabetic cardiomyopathy (DCM) rats.Methods A rat model of DCM was established by single intraperitoneal injection of streptozotocin (STZ, 60mg/kg), and whole cell patch-clamp technique was used to record the effects of 10-7mmol/L ghrelin on AP and Ito current density in the DCM rat ventricular myocytes.Results Compared to DCM group, Ghrelin of 10-7mmol/L could significantly prolong APD50 [(12.49±2.32)％;n=7, P=0.037] and APD90 [(26.29±5.13)％;n=7, P=0.006] and decrease Ito current peak value [(23.14±3.07)％;n=9, P=0.021] in DCM rat ventricular myocytes.Conclusion Exogenous ghrelin is involved in the electrophysiological reconstruction of the heart of diabetic rats by decreasing Ito current and prolonging APD in STZ-induced DCM rat ventricular myocytes.

Objective To explore the clinical characteristics,pathology,prognosis and proper treatment of tubular carcinoma of the breast. Methods The clinical data of 11 patients with tubular carcinoma of the breast treated in Peking Union Medical College Hospital were retrospectively analyzed.Results The incidence of tubular carcinoma of the breast account for 0.4% of the total breast cancer cases.Eight out of 11 cases had palpable painless lumps in the breast.Six cases received modified radical mastectomy,among which one patient received modified radical mastectomy of both sides.Four patients underwent breast conservation therapy.Sentinel lymph nodes biopsy was conducted in 2 patients.By immunohistochemistry ER was positive in 6 cases,PR was positive in 7 cases,2 cases were axiilary lymph node positive.Three patients received chemotherapy.Two patients received endocrine therapy(tamoxifen or aromatase inhibitor).Other patients received combined therapy including radiation,endocrine therapy and chemotherapy.All the patients have been followed up from 1 month to 7 years and within the period there is no recurrence,metastasis and death. Conclusion Tubulax carcinoma of the breast is a kind of low malignant tumor.Proper surgery and adjuvant therapy is important to improve survival and the quality of life.

Objective To discuss the expansion model of the eyeball and investigate the morphologic characteristics of high-my- opic eyeball through the dimensional measurement in high-myopia and emmetropia by MRI. Design Case controll study. Participants Thirty-two emmetropes (60 eyes) and 33 high myopes (60 eyes) were enrolled, without eye diseases and history of ocular surgery or in- jury. Methods 60 high-myopic eyes and 60 emmetropic eyes were measured with MRI (I.5T,PHILIPS) to get the data of three inner ocular dimensions, intraocular volume and the volume of different parts. Main Outcome Measures Three dimensions and volumes of eyeballs. Results The average value of axial (28.16?2.80 mm), horizontal (22.87+1.23 mm) and vertical length (23.40?0.99 ram) of high-myopic eyes were much bigger than those of emmetropic eyes(P=0.000), especially the axial length( with difference of 5.38 mm); The axial length was correlated with refractive error (0.36 mm/D,r~2=0.88, P=0.000). The average value of the whole ocular volume (7. 46?0.89 ml) and vitreous volume(6.90?0.8 ml) of the high myopic eyes were bigger than those of emmetropic eyes(P=0.000), while ante- rior segment volume and lens volume were about the same as that of emmetropic eyes (P=0.220, P=0.630). Conclusions The three di- mensions of high-myopic eyes were significantly longer than that of emmetropic eyes. In high myopes, the increased vitreous volume lead to the increase of the whole ocular volume. There may be two models in the ocular expansion of high myopia: global expansion and axial elongation expansion. More serious refractive error cause more obvious expansion in axial elongation.

Objective To detect the variations of the serum α-MSH and TNF-α in multiple-trauma patients and discuss their role in severity of casualties.Methods Fifty casualties were divided into two groups for study.There were 30 casualties with moderate severe trauma(ISS 16 ～ 25 point)and 20 patients with extreme severe trauma(ISS ＞ 25 point),and another 15 healthy subjects were enrolled as controls.The blood samples were obtained within 24 hours,and 3 days,5 days,7 days after admission.The serum levels of α-MSH and TNF-α in casualties with multiple injuries were determined by using enzyme-linked immunosorbent double antibody sandwich method(ELISA).The data were expressed in((x)± s),and analyzed with chi-square test and repetitive measures of ANOVA by using SPSS 13.0 package.P value less than 0.05 indicated statistical significance Results The serum α-MSH levels of casualties within 24 hours,and 3 days,5 days,7 days after injury in the two groups were much lower than those in the control group (P ＜ 0.01),while the serum TNF-α levels of casualties were much higher than those in the control group (P ＜0.01).The serum α-MSH levels of casualties with extreme severe traumawere lower,and the TNF-αlevels of casualties with extreme severe trauma were higher than those in patients with moderate severe trauma(P ＜0.01,respectively).There were negative correlations between two biomarkers 24 hours,5d and 7d after injury.Conclusions In casualties,the serum levels of α-MSH decreased and the serum levelsof TNF-α increased,and the degrees of changes were closely depended on the severity of trauma,the more severe the more significant changes.There was a negative correlation between two biomarkers.

Objective To investigate the clinical significance of contrast-enhanced transrectal ultrasound(CE-TRUS) in the perineal prostate biopsy. Methods A total of 116 patients was undergone prostate biopsy through the perineum under the direction of tansrectal ultrasound. Prostate biopsy standard was based on 2007 CUA revised guidelines for diagnosis and treatment of urological diseases.Color Doppler ultrasonography was used to check the prostate and to learn the prostate focal lesion,size, number and echo color Doppler flow characteristics. Of the 116 cases, 43 patients was undergone contrast-enhanced transrectal ultrasound. Results The biopsy results confirmed the diagnosis of prostate cancer was 64 cases, Benign prostatic hyperplasia was 52 cases. Of 43 cases who undergone contrast-enhanced transrectal ultrasound, Prostate cancer and Benign prostatic hyperplasia were 25 and 18 cases, respectively. CE-TRUS group and TRUS group showed no statistical difference between two groups. Analyzed the cases with PSA≤30 ng/ml, CE-TRUS group had a higher positive rate of biopsy (P=0.046). Conclusion TRUS guided transperineal biopsy of prostate might be an method for the diagnosis of prostate cancer with a higher accuracy rate. CE-TRUS can improve the biopsy positive rate of prostate cancer.

OBJECTIVETo explore the clinical outcomes of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF).

METHODSFrom January 2007 to February 2010, the data of 40 patients with osteoporotic vertebral compression fracture underwent treatment were retrospectively analyzed. Of them,20 patients were treated with PVP (PVP group), there were 8 males and 12 females with an average age of (66.37 +/- 2.34) years old (54 to 81); 20 patients were treated with PKP (PKP group), there were 11 males and 9 females with an average of (65.12 +/- 3.21) years old (56 to 79). Postoperative at 1 week, 12 weeks, 1 year, pain and daily life function were respectively assessed by visual analogue scale (VAS) and Barthel index (BI); and anterior height of responsibility vertebra, Cobb angle were measured by X-rays.

RESULTSIn PVP group, 1 case complicated with bone cement leakage without clinical symptoms and no operation to treat. No postoperative infection and deep vein thrombosis were found between two groups. All patients were followed up more than 1 year, pain and daily life function has obviously improved than preoperative (P < 0.01); and there was no significant difference on 1 week, 12 weeks, 1 year after operation (P > 0.05); there was no significant difference between two groups (P > 0.05). In PVP group, there was no significant difference in anterior height of responsibility vertebra, Cobb angle before and after operation;and in PKP group, postoperative data has obviously improved than preoperative (P < 0.01), but there was no significant difference postoperative at 1 week, 12 weeks, 1 year (P > 0.05); there was no significant difference between two groups at 1 week, 12 weeks, 1 year after operation.

CONCLUSIONBoth the methods can obviously relieve pain and completely or partly recover daily life function in treating OVCF. But PKP has advantages of recovery of anterior height of responsibility vertebra and correction of Cobb angle, especially for serious compression.

The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.
