Metabolic syndrome (MetS) is a serious threat to public health worldwide with an increased risk of developing type 2 diabetes, cardiovascular diseases and all-cause morbidity and mortality. In this study, a urinary metabolomic approach was performed on high performance liquid chromatography quadrupole time-of-flight mass spectrometry to discriminate 36 male MetS patients and 36 sex and age matched healthy controls. Pattern recognition analyses (principal component analysis and orthogonal projections to latent structures discriminate analysis) commonly demonstrated the difference between MetS patients and no-MetS subjects. This study found 8 metabolites that showed significant changes in patients with MetS, including branch-chain and aromatic amino acids (leucine, tyrosine, phenylalanine and tryptophan), short-chain acylcanitine (tiglylcarnitine), tricarboxylic acid (TCA) cycle intermediate (cis-aconitic acid) and glucuronidated products (cortolone-3-glucuronide and tetrahydroaldosterone-3-glucuronide). The candidate biomarkers revealed in this study could be useful in providing clues for further research focusing on the in-depth investigation of the cause of and cure for MetS.

The evolution of the quality control concepts of medical products within the global context and the development of the quality control technology of Chinese medicine are briefly described. Aimed at the bottlenecks in the regulation and quality control of Chinese medicine, using Big Data technology to address the significant challenges in Chinese medicine industry is proposed. For quality standard refinements and internationalization of Chinese medicine, a technological innovation strategy encompassing its methodology, and the R&D direction of the subsequent core technology are also presented.

Objective To observe the effects of fosinopril(FOS),a new generation angiotensin-converting enzyme inhibitor(ACEI),on protein and mRNA expression of transforming growth factor-?_1(TGF-?_1) of rat glomerular mesangial cell(GMC) induced by lipopolysaccharide(LPS);to demonstrate the preventive mechanism against glomerular sclerosis by applying FOS.Methods The cultured GMC in classic way were divided into 3 groups:control group;LPS group;LPS+FOS group.TGF-?_1 concentration in GMC supernatant fluid was detected by ELISA;TGF-?_1 mRNA expression was determined by semiquantitative real-time RT-PCR.Results LPS group was obviously higher than control groups in TGF-?_1 secretion and mRNA expression,while LPS+FOS group decreased distinctively in TGF-?_1 secretion and mRNA expression compared with LPS group.Conclusions FOS has obviously inhibited on TGF-?_1 expression of rat GMC both at protein level and mRNA level,which reveals that it may be an important mechanism by FOS on restraining the development of glomerulosclerosis.

Objective To detect the gene expression of Pax6 in retinoblastoma (Rb).Design Experimental study.Participants Six cases of fresh Rb tumors and two established Rb cell lines.Six cases of retina tissues as normal control group.Methods Pax6 gene ex- pression was assessed in two established Rb cell lines,six primary tumors and six cases of retina tissues using the reverse transcriptase polymerase chain reaction (RT-PCR) and Western blot.Main Outcome Measures Expression of Pax6 gene in fresh retinoblastoma tis- sue and cell lines.Results The mRNA of Pax6 gene was positive in all two established Rb cell lines and the six primary Rb tumors using RT-PCR.The protein of Pax6 gene was also positive in Western blot.Pax6 mRNA and protein expression in the Rb tumors were increased compared with normal control group (P

OBJECTIVETo retrospectivly compare the clinical efficacy of dynamic hip screw (DHS) with proximal femoral nail anti-rotation (PFNA) for the treatment of unstable intertrochanteric fractures in the elderly.

METHODSTotally 92 elderly patients with unstable intertrochanteric fractures were treated with DHS [including 27 males and 23 females with a mean age of (72.5 +/- 5.3) years old] and PFNA [including 22 males and 20 females with a mean age of (72.8 +/- 5.8) years old] from August 2008 to August 2012. The data of operation time,blood loss (obvious and hidden blood loss), bedridden time, down load time, postoperative complications and Harris hip function score were recorded and compared.

RESULTSBoth of two groups were followed-up for 10 to 18 months with an average of 13.5 months. PFNA was implanted with a significantly smaller incision and shorter clinical healing time, less blood loss,while hidden blood loss were more. Postoperative complications, therapeutic effects and Harris score in PFNA group were better than that of DHS group.

CONCLUSIONFor treatment of senile patients with unstable intertrochanteric fractures, PFNA was superior to DHS in reducing complication rates, recovering hip joint, while DHS could reduce perioperative blood loss in treating type II a, II b and III fracture.
