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 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 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 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 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 test the the association between PRODH gene variant rs385440 and the susceptibility to schizophrenia and the severity of schizophrenia in Guangxi Zhuang and Han population,further exploring the genetic mechanisms of schizophrenia in Guangxi Zhuang and Han population.MethodsThe schizophrenia patients were diagnosed according to ICD-10 criteria in this study.The subjects in the association analysis were 282 unrelated schizophrenia patients(94 Zhuang and 188 Han) and 282 healthy controls (94 Zhuang and 188 Han).A quantitative real-time PCR TaqMan MGB experimental method was carried out to analysis rs385440.The clinical psychotic symptoms of 246 schizophrenia patients (83 Zhuang and 163 Han) were assessed by PANSS.Statistical analyses were carried out with SPSS13.0 for windows.ResultsThere was no statistically significant difference in different allele and genotype frequencies of rs385440 between schizophrenia cases and controls in Zhuang samples,Han samples and combined samples respectively (P＞ 0.05 ).In Zhuang schizophrenia patients the score of N4 (passive/apathetic social withdrawal) item in A allele carriers (3.28 ± 1.34) was higher than that of G allele carriers ( 2.40 ± 1.36 ) significantly (P ＜ 0.05 ),and the score of G12 ( lack of judgment and insight) item in A allele carriers(4.92 ± 1.55 ) was higher than that of G allele carriers ( 4.12 ± 1.85 ) significantly (P ＜ 0.05 ).Conclusion There is no association between PRODH gene variant rs385440 and the susceptibility to schizophrenia in Guangxi Zhuang and Han population.Rs385440 associated the severity of passive/apathetic social withdrawal symptom and poor attention symptom of schizophrenia in Zhuang.

SD rats were injected with streptozotocin and fed with high fat diet,used as type 2 diabetic model. Transcription factor Fox01 [in nucleus (15.00±1. 15 vs 6.45±0. 62) %, P<0.05], Caspase-3 [(23.73 ±1.48 vs 6.30±2.20)% ,P<0.01] expressions in pancreatic istet β cells and the positive rate of islet β cells apoptosis[(22.29±1.84 vs 6.25±2.42) %, P<0.01] in diabetic rats were higher than those of control rats. The islet cells which highly expresed Fox01 (in nucleus)and caspase-3 were just the apoptotic islet cells. Therefore,Fox01 may be involved in regulating apoptosis of islet β cells in type 2 diabetes.

Objective To evaluate the applied value of functional immunity measured by the ImmunKnow assay in the diagnosis of post-transplant infection in Chinese 1iver recipients.Methods Thirty-eight normal adults and 68 adult liver transplant recipients were under investigation.Whole blood samples from either normal volunteers(each sample for one person)or the liver recipients(one or more samples for one person)were collected freshly and cultured within 6h.The CD4+T cells were selected and their ATP value was assayed the next day.The liver recipients were grouped in stable status(n=52)or infection(n=64)according tO their clinieal manifestation.Results The average ATP value in the recipients with infection after liver transplantation was 165.7±100 μg/L,significantly lower(P＜0.05)than that in stable recipients(309±126 μg/L)or normal volunteers (292±83 μg/L).The low ATP levels in post-transplant recipients had fair good correlation to infection clinically(RR=0.5021,P＜0.01).Infectious risk was high when ATP value was less than 165μg/L(OR=11,95%CI 3.9-32.2,P＜0.01).Specificity and sensitivity of low ATP value in post-transplant infection were 86.53%and 73.81% respectively,Conclusion ImmuKnow assay provides a new tool in monitoring immune status in post-transplant recipients,and call helpfully predict and diagnose clinical infection.

A method of on-line solid phase extraction ( SPE )-two dimensional liquid chromatography electrospary-tandem mass spectrometric method was established for the determination of Teicoplanin concentrations in human cerebrospinal fluid. Cerebrospinal fluid samples were treated by the on-line SPE treatment, and analyzed by LC-MS/MS. The chromatographic separation was performed on a Shiseido CAPCALL-PAK C18 column with gradient elution by using 25 mmol/L ammonium acetate ( pH 6. 0 )-acetonitrile as mobile phases, and the flow rate of 1 mL/min. Detection was carried out under the selected reaction monitoring ( SRM) in positive ionization mode with scopolamine hydrobromide as internal standard. Matrix-matched calibration curves with good correlation coefficients (R2=0. 9993, n=6) were obtained in the concentration range of 25-5000 μg/L. The average recoveries varied from 100. 8% to 109. 9%. The intra-and inter-day precisions were less than 6%. The method is proved to be rapid, sensitive, accurate, and suitable to determine Teicoplanin concentrations in human cerebrospinal fluid.
