Conclusion Endoscopic-assisted catheterization is effective in the treatment of bulbous urethral injury .

Objective To provide decision-making information for the spread of techniques that improve the quality of neonates. Methods A systematic study was made of the political, technical, economic and social viability of neonatal disease screening in China by means of economic and policy evaluation, sociological analysis, and statistical analysis. Results Neonatal disease screening was conducted in 29 provinces throughout the country. However, there was a great difference between the provinces in screening coverage. In order to strengthen control, 16 provinces issued methods or regulations concerning neonatal disease screening. Since the Ministry of Health did not issue relevant control methods that would standardize the responsibilities of the organizations undertaking the screening, problems affecting the safety and effectiveness of neonatal disease screening became increasingly prominent. Conclusion It is necessary and viable to conduct neonatal disease screening in China. But macro control of the work by the government needs to be reinforced. The Ministry of Health ought to issue as soon as possible methods for controlling neonatal disease screening and relevant technical criteria. At the same time publicity of the work needs to be strengthened in society so as to give it impetus throughout the country.

Recent studies show that resveratrol is characterized with its antioxidative and anti-inflammatory effects, and plays an important role in the prevention and treatment of colorectal cancer through modulating intracellular carbohydrate and ceramide metabolism, activating tumor suppressors such as activator of transcription 3 and peroxisome proliferators-activated receptor γ, down-regulating the expression of kirsten rat sarcoma viral oncogene and inhibiting the epithelial-to-mesenchymal transition process of cancer cells.In addition,resveratrol exhibits its broad application prospects in combination therapy.

Objective To explore the related risk factors of renal function after partial nephrectomy,and provide the reference for clin-ic. Methods The data of 31 patients with small renal cancer in our hospital from January 2010 to June 2014 were analyzed. Before and after the treatment,the relationship of renal glomerular filtration rate ( GFR) with the change and clinical pathological factors were analyzed,the single factor analysis used t test,multiple factors analysis adopted multi-factor unconditioned logistic regression analysis. Results Single fac-tor analysis results showed that renal function after partial nephrectomy was closely related to the age,diabetes mellitus,blocking time,the size of the tumor,renal volume reduction ratio,the difference was statistically significant (P<0. 05). Many factors of logistic regression showed that it was closely related to the age,blocking time,renal volume reduction ratio(P<0. 05). Conclusion The age,blocking time,renal vol-ume reduction ratio are risk factors for renal function after partial nephrectomy.

Objective To investigate the coronary arterial lesions (CAL) in Kawasaki disease (KD) in Jilin Province and Inner Mongolia Autonomous Region from 1999 through 2012 and evaluate the influence of glucocorticoids (GCs) on prognosis.Methods We performed a retrospective study among patients of KD in Jilin Province and Inner Mongolia Autonomous Region from 1999 to 2012,in order to observe CAL in KD,the incidence of sequelae and the influence of CGs on disease outcome.Comparison between groups was carried out by Chi-square test.Results Eight hundred and ten KD cases were reported from 32 hospitals and 787 patients accepted an Echo examination,as the main objective of this study.Fivehundred and forty were boys and 247 were girls,with the male to female ratio of 2.19:1,of which 498 cases (63.3％) had CAL.Most CAL occurred in patients at 58 day to 14 year old (2.7±2.4).The most common abnormality was CAL including dilatation (49.5％) and stenosis (13.4％).Compared incomplete to complete KD,the result showed that the occurrence of CAL was similar between these two groups,no significant differences could be found between different gender.Nineteen (2.4％) of them had cardiac sequelae and the male/female ratio was 3.67:1.The younger the age,the higher the incidence of cardiac sequelae.The most frequent cardiac sequelae was coronary artery dilatation.GCs therapy could increase the occurrence of CAL [80.2％(97/121) vs 62.6％ (419/666),x2=8.71,P＜0.05].Conclusion CAL is not different between patients with complete or incomplete KD and the occurrence of CAL is not associated with gender,but with age.The younger the age,the higher the incidence of CAL and the higher the incidence of cardiac sequelae.It is possible that patients treated with GCs are prone to CAL.

Objective To evaluate the diagnostic value of the aldosterone-renin ratio (ARR) for primary aldosteronism (PA). Methods Serum aldosteronos ( ALD ) and plasma renin activities (PRA)among 44 subjects with primary aldosteronism, 9 subjects with phecchromocytoma, 8 subjects with nonfunctional adrenal tumors, 12 subjects with Cushing syndrome, 4 subjects with stenosis of renal artery and 13 subjects with primary hypertension were retrospectively reviewed. ARR was calculated. The receiver operating characteristics (ROC) curves for every index were used to evaluate diagnostic value. Results The area under the curve(AUC) in the ROC curve of ALD in a supine position was 0. 947, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ALD in upright position was 0. 889, the cut-off value of ALD diagnosis of PA. The AUC for the ROC curve of ARR in a supine position was 0. 978, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ARR in upright position was 0. 981, the cut-off value of specificity. If ARR was combined with ALD in upright position was used, the diagnostic value was better than either index. When ALD > 275 ng/L and the AUC for the ROC curve in upright position was 0. 989,specificity. Conclusions The diagnostic value of ARR in diagnosis of primary aldosteronism is higher than ALD and PRA. ARR in upright position is better than that in supine position, especially when combined with ALD > 275 ng/L in upright position.

To investigate the effects of Caulis Sargentodoxae Granule (CSG), a compound traditional Chinese herbal medicine for treating endometriosis, on expressions of vascular endothelial growth factor (VEGF) and its receptor-2 fetal liver kinase-1 (Flk-1) in rats with endometriosis.

Cell-penetrating peptides (CPPs) offer a non-selective and receptor-independent mode to promote cellular uptake. Although the non-specificity of CPP-mediated internalization allows this approach applicable to a wide range of tumor types potentially, their universality is a significant obstacle to their clinical utility for targeted delivery of cancer therapeutics and imaging agents. Accordingly, many reports have focused on selective switching of systemically delivered inert CPPs into their active form in lesions (tumor). In this review, our attention is mainly confined to such an enzyme-sensitive domain incorporated delivery system with activatable CPPs (ACPPs), which have displayed the exciting strength in balancing the CPPs' pros and cons, and potential in the treatment and diagnosis of some diseases.

To study the effect of endotoxin on liver apoptosis, L02 liver cells were cultured and passaged in vitro, and then stimulated by endotoxin at 10 mg/mL for 4, 8, 16 and 24 h respectively. Liver apoptosis was flow cytometrically and fluorescently detected. Immunohistochemistry was used to detect the delivery of smac and caspase9. The delivery of liver cell smac and the activity of caspase3 were measured by caspase3 assay kit. The hepatic failure models of rats were established by using D-galactosamine. The blood serum and liver tissues were collected for the detection of the liver function, the level of endotoxin and the activity of caspase3 by using chromogenic substrate limulus amebocyte lysate method (LAL) and caspase3 active assay kit. The expression of smac and caspase9 in liver cells was detected by Western blotting. With in vitro study, the L02 cells stimulated by LPS condensed into conglobation and formed apoptotic bodies. After those cells were stained by hoechst, the apoptotic cells displayed blue color under the fluorescent microscope. The apoptosis rate was increased over time and the apoptosis was mainly of advanced stage. Meanwhile, the rate of smac delivery and activity of caspase9 and caspase3 were increased on L02 cell membrane. In vivo, hepatic failure and obvious endotoxemia were induced by injection of more than 200 mg/kg D-GalN. Hepatic mitochondria smac was reduced with dosage of D-GalN and, on the contrary, the activity of caspase3 was increased. D-GalN at 200 mg/kg increased Caspase9 while D-GalN at 300 mg/kg decreased caspase9. Mitochondria signal channel plays an important role in the endotoxin-induced apoptosis of hepatic cells by promoting the release of smac from mitochondria to cytoplasm and activating caspase9 and caspase3 in its low-level channel.
