Objective To investigate the opportunity of non-bladder perfusion after transurethral enucleation and resection of prostate (TUERP).Methods Sixty patients suffered from TUERP were divided into two groups according to random number with 30 patients in each group.The observation group was halted bladder perfusion on the next day of operation,and the control group was halted after 3 d.The ambulation time,the rates of urinary tract infection and contraction of bladder and quality of life were recorded and analyzed.Results Contraction of bladder in 1 case and no urinary tract infection happened in the observation group and 9 cases and 10 cases in the control group respectively; the differences between the two groups were significant ( x2 =7.680,12.000,respectively ; P < 0.05 ).Score of QOL one month later in the observation group was (0.75 ± 0.15 ) and ( 1.50 ± 0.31 ) in the control group,and the difference was significant ( t =- 11.995,P <0.01 ).Conclusions The halted bladder perfusion in the next day after operation can decrease ambulation time,decrease the rates of urinary tract infection and contraction of bladder and improve quality of life.

OBJECTIVETo study the clinical and pathological features of drug-induced liver injury (DILI).
METHODSLiver specimens were obtained through needle biopsies from 100 patients with DILI. The histological preparations of the specimens were stained with haematoxylin eosin, several histochemistry methods, and immunohistochemistry stains. The pathological changes of the livers were analyzed together with the patients's clinical data. The patients were divided into two groups, an acute DILI group (n=39) and a chronic DILI group (n=61), based on their clinical courses and histological changes in their livers. In the chronic DILI group, the clinical courses were longer than 6 months and/or fibrosis or cirrhosis occurred in their liver tissues.
RESULTSAmong our cases the leading cause of DILI was Chinese herb medicine, accounting for 21% of the 100 cases; steroids induced cases were 11% of the total. 78% of the patients presented elevated serum transaminases and/or jaundice. The degree of transaminases elevation and the frequency of jaundice happening in the acute group were significantly higher than those in the chronic group (P less than 0.05). The histopathological liver changes in these DILI cases included: (1) necrosis commonly occurred in acinar zone 3, (2) abundant neutrophil and/or eosinophil infiltrations, (3) hepatocytic and/or canalicular cholestasis with little or no inflammation, (4) microvesicular steatosis mixed with macrovesicular steatosis, and (5) presentation of epitheloid cell granuloma. There were no significant differences in liver histopathology between the acute and the chronic DILI groups, except that the fibrosis and the ductular proliferation were different.
CONCLUSIONDILI has become a notable liver disease in mainland China, and the use of Chinese herbal medicine must be improved, standardized and regulated more closely.

Objective: To establish a method for isolation and purification of fetal membrane derived adherent cells (FMDACs) , and investigate their biological characteristics. Method: FMDACs were isolated with trypsin inducing and cultured in vitro. FMDACs were induced to differentiate into osteoblasts and adipocytes. FACS and immunocytochemistry technique were used to examine the cell surface antigen. The genetic stability was verified by karyotype analysis. Results: FMDACs were successfully isolated and expanded in vitro. They had strong proliferative ability. FMDACs were positive for CD44 and CD29, but negative for CD34, CD14 and CD45. FMDACs were differentiated into osteoblasts and adipocytes after inducement. The karyotype was stable in the sixth-passaged FMDACs and the tumorigenicity was not found. Conclusion; FMDACs have the possibility of multipotent stem cells, which have strong capacities of self-renewal and multidirectional differentiation. The genetic background of FMDACs is stable. FMDACs may be used as a kind of novel seed cells for tissue engineering.

In this study,nine hybridoma cells secreting monoclonal antibodies against deltamethrin were prepared,and the monoclonal antibody 4D4E11 with best sensitivity was selected to develop indirect enzyme-linked immunosorbent assay (ic-ELISA) and gold nanoparticle-based lateral flow immunoassay (LFIA) for detection of deltamethrin. The optimal working buffer for ic-ELISA was 0.01 mol/L phosphate buffer (pH 7.4) containing 0.2 mol/L NaCl and 20% methanol,while 0.01 mol/L phosphate buffer (pH 7.4) containing 1 mol/L NaCl,5‰Tween-20 and 10%methanol for LFIA. Under the optimal conditions,the half inhibition concentration (IC50) and limit of detection (IC10) of ic-ELISA were 10.60 ng/mL and 1.43 ng/mL respectively,and the limit of detection of the developed LFIA was 0.5μg/mL. The developed ic-ELISA and LFIA showed no cross-reactivities (CRs) with eight kinds of analogues of deltamethrin,which indicated the excellent specificity of proposed immunoassays. The average recoveries of the ic-ELISA in spiked tomato,cabbage and lettuce samples were 79.8%-92.6%with relative standard deviations of 0.8%-5.5%. The detection results of LFIA were consistent with the spiked concentrations in the range of 1-5 mg/kg. Meanwhile,the results of ic-ELISA and LFIA showed close correlation with high performance liquid chromatography (HPLC) in the test of blind lettuce samples. The experimental results demonstrated that the two immunoassays proposed here were suitable for rapid detection of deltamethrin with high sensitivity and high accuracy.

This study aimed to determine and quantitate the mammographic and sonographic characteristics in 13 cases of solid neuroendocrine breast carcinoma (NEBC) and to analyze the association of radiological findings with the clinical and histopathologic findings. The clinical data and imaging findings of 13 female patients with histologically confirmed solid NEBC were reviewed. Imaging data were evaluated by two radiologists for a consensual diagnosis. All patients presented with one palpable mass; only 1 experienced occasional breast pain, and 5 complained of fluid discharge. In 7 patients, the masses were firm and mobile. Regional lymph node metastasis was noted in only 1 patient. For the 10 patients who underwent mammography, 6 had a mass, 1 had clustered small nodules with clustered punctuate microcalcifications, 2 had asymmetric focal density, and 1 had solitary punctuate calcification. Most of the masses had irregular shape with indistinct or microlobulated margins. For the 9 patients who underwent ultrasonography (US), 9 masses were depicted, all of which were hypoechoic, mostly with irregular shape and without acoustic phenomena. Different types of acoustic phenomena were also identified. One patient had developed distant metastases during follow-up. NEBC has a variety of presentations, but it is mostly observed on mammograms as a dense, irregular mass with indistinct or microlobulated margins. Sonographically, it typically presents as an irregular, heterogeneously hypoechoic mass with normal sound transmission. Histories of nipple discharge and calcification observed using imaging are not rare.
