Objectives: Pathological nipple discharge (PND) may indicate malignant breast lesions. As the role of shear wave elastography (SWE) in predicting these malignant lesions has not yet been evaluated, we aim to evaluate the diagnostic value of SWE for this condition. Design: Prospective diagnostic accuracy study comparing a combination of qualitative and quantitative measurements of SWE (index test) to a ductoscopy and microdochectomy for histological diagnosis (reference test). Setting: Fuzhou General Hospital of Nanjing military command. Participants: A total of 379 patients with PND were finally included from January, 2011 to March 2014, after we screened 1084 possible candidates. All participants were evaluated through SWE, with qualitative parameters generated by Virtual Touch tissue imaging (VTI) and quantitative parameters generated by Virtual Touch tissue quantification (VTQ). All the patients were consented to receive a ductoscopy and microdochectomy for histological diagnosis, and the results were set as a reference test. Outcome measures: Sensitivity and specificity of the combined VTI and VTQ of the SWE for detection of malignancy in patients with PND. Results: The 379 participants presented with 404 lesions. The results of pathological examination showed that 326 (80.7%) of the 404 lesions were benign and the other 78 (19.3%) were malignant. An area under the curve of elasticity score, VTQm and VTQc, were 0.872, 0.825 and 0.857, respectively, with the corresponding cut-off point as 2.50, 2.860 m/s and 3.015 m/s, respectively. After a combination of these measurements, the sensitivity, specificity, and positive and negative predictive value (PPV and NPV), were 89.7%, 72.1%, 43.5% and 96.7%, respectively. The sensitivity analysis showed 82% of the sensitivity and 96.8% of the specificity, in which patients with no pathological findings in ductoscopy were excluded. Conclusions: Ultrasonographic elastography is sensitive for patients with PND and could be used as a triage test before ductoscopy examination. Studies for further improvement of diagnostic sensitivity are warranted.

Background: Statins are widely prescribed to reduce cholesterol levels in the prevention of atherosclerotic cardiovascular disease. However, the debate about the effect of statins on cancer risk remains unsettled. The aim of this study was to investigate the association of utilization of statins with the risk of gastric cancer by carrying out a meta-analysis. Methods: A literature search was performed on PubMed and EMBASE up to March 2013 to identify the cohort or case-control studies or randomized controlled trials (RCTs) that examined the relationship between statins use and the risk of gastric cancer. The bibliographies of the retrieved articles were also reviewed to identify additional studies. A random-effects model was used to calculate the summary relative risks (RRs) with 95 % confidence intervals (CIs). Results: Three post-hoc analyses of 26 RCTs involving 290 gastric cancers and eight observational studies totaling 7,321 gastric cancers were included. Statins use was shown to be significantly associated with a 27 % reduction in the risk of gastric cancer (RR = 0.73, 95 % CI = 0.58-0.93), with considerable heterogeneity among studies (I 2 = 88.9 %). Excluding one study in which all subjects are diabetic patients obtained an attenuated, but homogeneous result (RR = 0.85, 95 % CI = 0.80-0.91, I 2 = 0.0 %). These findings were consistent in the subgroup analysis. Conclusion: A meta-analysis of existing evidence, primarily from observational studies, indicates that use of statins reduces the risk of gastric cancer. © 2013 Springer-Verlag Berlin Heidelberg.

The application of sirolimus (SRL) as immunosuppressive agent is hampered by its poor water solubility and narrow therapeutic range. The self-microemulsifying drug delivery system (SMEDDS) succeeded in improving the solubility of SRL in our previous work. In this study, the formulation of the SMEDDS was further optimized by investigating the influence of the excipients including the media, antioxidant and organic acid. It was demonstrated that addition of 0.20% of citric acid in SMEDDS most efficiently promoted the stability of SRL under high temperature (402C), high humidity (relative humidity 905%) or strong light irradiation (4500500lx). SMEDDS absorbed by microcrystalline cellulose (MCC) was mixed with hydroxypropyl methylcellulose (HPMC) to prepare tablets. The optimal formulation composed of 15% of HPMC 100 LV with hardness of 120N, which had a sustained release of 12h. Results of X-ray powder diffraction and differential scanning calorimetry demonstrated that SRL in the tablets was in amorphous or molecularly dispersed state. The SMEDDS-tablets presented as promising substrates for water insoluble drugs with enhanced stability and extended release.

To investigate the influence of partial deletions in the AZFc region of the Y chromosome on spermatogenesis. We selected 9 sequence tagged sites (sY1258, sY1291, sY254, sY255, sY1201, sY1206, sY1161, sY1197 and sY1191) in the AZFc region of the Y chromosome, with ZFX/ZFY and SRY (sY14) as the interior control. We amplified by multiplex PCR the DNA of 160 patients with azoospermia or severe oligozoospermia that showed no microdeletion of the Y chromosome (the case group) and another 76 males with normal fertility (the control group). For the individuals suspected of DAZ gene deletion, we detected the single nucleotide polymorphism sites (SNPs) in the four copies of the DAZ gene by single nucleotide variation (SNV) analysis to determine the types of DAZ copy deletion. In the case group, there were 10 cases of gr/gr (sY1291) deletion (6.3%), 14 b2/b3 (sY1191) deletion (8.8%), 1 sY1291,sY1197 deletion (0.6%), 1 b1/b2 deletion (0.6%) and 1 b1/b3 deletion (0.6%), while in the control group, there were 4 cases of gr/gr deletion (5.3%) and 4 b2/b3 deletion (5.3%). SNV analysis showed DAZ1/DAZ2 deletion in all those with gr/gr and those with b1/b3 deletion, DAZ3/DAZ4 deletion in those with b2/b3 deletion, and DAZ-SNV sY587 deletion in 1 case of sY1291, sY1197 deletion, but no DAZ deletion was found in 1 case of b1/b2 deletion. B2/b3 (sY1191) and gr/gr (sY1291) deletions are genomic polymorphisms and quite common in the normal Chinese population; while b1/b2, b1/b3, and sY1291, sY1197 deletions may be high risk factors of dyszoospermia.

Severe acute pancreatitis (SAP) is initiated by the premature activation of digestive enzymes within the pancreatic acinar cells, leading to self-digestion and inflammatory responses in pancreatic ductal cells, thus giving rise to systemic inflammatory response syndrome (SIRS). The most common and serious SIRS is pancreatitis-associated lung injury, and inflammatory mediators play an important role in its pathogenesis. Bone marrow-derived mesenchymal stem cells (MSCs) are differentiated into alveolar endothelial cells to replace the damaged alveolar endothelial cells and inhibit inflammatory response in the injured lung tissues. In this study, we aimed to investigate the therapeutic effect of bone marrow-derived MSCs in rats with pancreatitis-associated lung injury. Experimental SAP was induced by a retrograde injection of 5% sodium taurocholate into the biliopancreatic duct of 75 male Sprague-Dawley rats, which were divided into the SAP group (n=25), the MSC group (n=25) and the sham-operated group (n=25) to explore the pathology and function of lung tissues and the regulation of inflammatory mediators. Pulmonary edema was estimated by measuring water content in the lung tissues. Pulmonary myeloperoxidase (MPO) activity was detected using spectrophotometry. Serum amylase was detected using the Automatic Biochemistry Analyzer. Tumor necrosis factor-α (TNF-α) and substance P (SP) mRNA levels were determined by quantitative reverse transcriptase-polymerase chain reaction. Our results showed that serum amylase activity was significantly decreased in the MSC group compared to the SAP group. Pulmonary edema was significantly diminished (p<0.05) in the MSC group compared to the SAP group. Typical acute lung injury was observed in the SAP group, and the pathological changes were mild in the MSC group. The expression of TNF-α and SP mRNA in lung tissue was diminished in the MSC group compared to the SAP group. In conclusion, MSC transplantation attenuates pulmonary edema and inflammation, and reduces the mRNA expression of TNF-α and SP in pancreatitis-associated lung injury.

Severe acute pancreatitis (SAP) is an acute inflammatory disease of the pancreas that involves various distant tissues and organs. This study aimed to investigate post-tissue injury repair by mesenchymal stem cells (MSCs) in a rat model of SAP. A total of 54 pathogen-free adult male SD rats were randomly assigned to the groups SAP, SAP + MSCs and sham-operated (SO). SAP was induced by 4% sodium taurocholate, and MSCs were injected via the dorsal penile vein 1 h later. The amylase activity, and tumor necrosis factor (TNF)-α and diamine oxidase (DAO) levels were measured with an enzyme-linked immunosorbent assay (ELISA), while the expression of aquaporin (AQP)-1 was evaluated by immunohistochemical staining. The pathological score of intestinal tissues was also compared among groups. Marked improvement in intestinal necrosis, villi shedding and infiltration of inflammatory cells was observed in the SAP + MSCs group compared to the SAP and SO groups. Amylase, TNF-α, and DAO levels were significantly increased in the SAP + MSCs group. The intestinal expression of AQP-1 was increased at 12 and 24 h post-MSC transplantation compared to the SO group. Rats of the SAP + MSCs group displayed higher pathological scores compared to the SAP group at all time points. Overall, these data showed that MSCs can inhibit systemic inflammation and reduce TNF-α release in a rat model of SAP-induced intestinal injury, suggesting that MSCs exert protective effects on the intestinal barrier during SAP.

To investigate the role and potential mechanisms of bone marrow mesenchymal stem cells (MSCs) in severe acute peritonitis (SAP). Pancreatic acinar cells from Sprague Dawley rats were randomly divided into three groups: non-sodium deoxycholate (SDOC) group (non-SODC group), SDOC group, and a MSCs intervention group (i.e., a co-culture system of MSCs and pancreatic acinar cells + SDOC). The cell survival rate, the concentration of malonaldehyde (MDA), the density of superoxide dismutase (SOD), serum amylase (AMS) secretion rate and lactate dehydrogenase (LDH) leakage rate were detected at various time points. In a separate study, Sprague Dawley rats were randomly divided into either an SAP group or an SAP + MSCs group. Serum AMS, MDA and SOD, interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF)-α levels, intestinal mucosa injury scores and proliferating cells of small intestinal mucosa were measured at various time points after injecting either MSCs or saline into rats. In both studies, the protective effect of MSCs was evaluated. In vitro, The cell survival rate of pancreatic acinar cells and the density of SOD were significantly reduced, and the concentration of MDA, AMS secretion rate and LDH leakage rate were significantly increased in the SDOC group compared with the MSCs intervention group and the Non-SDOC group at each time point. In vivo, Serum AMS, IL-6, TNF-α and MAD level in the SAP + MSCs group were lower than the SAP group; however serum IL-10 level was higher than the SAP group. Serum SOD level was higher than the SAP group at each time point, whereas a significant between-group difference in SOD level was only noted after 24 h. Intestinal mucosa injury scores was significantly reduced and the proliferating cells of small intestinal mucosa became obvious after injecting MSCs. MSCs can effectively relieve injury to pancreatic acinar cells and small intestinal epithelium, promote the proliferation of enteric epithelium and repair of the mucosa, attenuate systemic inflammation in rats with SAP.

MicroRNA (miR)-199b-5p has been reported to be upregulated in human osteosarcoma tissues and participate in the Notch signaling in osteosarcoma cells. This study was aimed to investigate the associations of miR-199b-5p expression with tumor progression of primary osteosarcoma, and to deepen the understanding of its involvement in carcinogenesis. Quantitative real-time reverse transcriptase-polymerase chain reaction was performed to detect expression levels of miR-199b-5p in 98 osteosarcoma and corresponding adjacent normal tissues. Then, the correlations of its expression with clinicopathological characteristics and patient prognosis were statistically analyzed. Moreover, in vitro assays were performed to assess the effects of miR-199b-5p on the proliferation, migration and invasion of two human osteosarcoma cell lines MG63 and U2OS. Compared to normal controls, miR-199b-5p expression was significantly upregulated in osteosarcoma tissues (P < 0.001). In addition, the expression levels of miR-199b-5p in osteosarcoma patients with high tumor grade (P = 0.008), positive metastasis (P = 0.001) and positive recurrence (P = 0.001) were markedly higher than those with low tumor grade, negative metastasis and negative recurrence. Moreover, osteosarcoma patients with high miR-199b-5p expression showed shorter overall survival (P <.001) and shorter disease-free survival (P < 0.001) than those with low expression. Furthermore, the inhibition of miR-199b-5p significantly suppressed cell proliferation, and reduced the migratory and invasive abilities of osteosarcoma cells. This study offer the convincing evidence for the first time that the increased expression of miR-199b-5p may play crucial roles in aggressive progression and poor prognosis of human osteosarcoma. miR-199b-5p may function as an oncogene by positively regulating the malignant potentials of this neoplasm.
