High performance liquid chromatography-time-off-flight mass spectrometer (HPLC-TOFMS) technology coupled with partial least squares discriminant analysis (PLS-DA) processed by SIMCA-P software was applied to investigate serum endogenous metabolites alternations of valsartan in spontaneous hypertension rats (SHR). And MetPA platform was used to connect identified potential biomarkers in corresponding metabolic pathways to find possible therapeutic mechanism of valsartan. Valsartan significantly declined the blood pressure of SHRs (P < 0.05) at fourth week. The metabolic profiling significantly changed and four metabolites involved in G protein-coupled pathway were identified. Metabolomics is able to detect holistic and microcosmic alternations in organism, so as to elucidate therapeutic mechanism of drugs.

Objective To investigate the anatomic feature and exposing methods of recurrent laryngeal nerve(RLN) in thyroid surgery. Methods The data of 327 cases of thyroid tumor were analyzed retrospectively. The anatomic feature, injury and prevention of RLN were discussed. Of all the cases, 293 RLNs (242 cases) were anatomically exposed. Results The temporary injury rates of RLN was 1.65% (4/242) in the exposed group and 8.23% (7/85) in the unexposed group with a persistent injury rate of 2.35%(2/85). The differences of temporary injury rates and persistent injury rates between the two groups were statistically significant (P<0.05). 67.23% (197/293) of the RLNs had two branches before entering larynx, 61.09%(179/293) of RLNs were posterior to the inferior thyroid artery and 31.39% (92/293) anterior to the inferior thyroid artery, 4.09% (12/293) passed through the bifurcation of inferior thyroid artery, and 4. 13% (10/293) were not related to the inferior thyroid artery. The incidence of non-recurrent laryngeal nerve (inferior laryngeal nerve) was 0.68% (2/293). Conclusions The anatomic relation of RLN is relatively complicated along its journey. The injury of RLN could be reduced with designed exposal during the thyroid surgery.

Objective To study the relationship between peripheral blood hemoglobin (HB) and blood pres- sure.Methods We performed a cross-sectional analysis in 1153 subjects aged 29-83 years.Waist circumfer- ence,HB,blood pressure,high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL- C),triglycerides (TG),total cholesterol (TC) were determined.Results ①With the increasing of blood pres- sure,HB had a clearly increasing trend (HB,normotensive:137.5?14.7 vs prehypertension:143.4?14.4 vs hy- pertension:144.3?13.8 g/L,P

OBJECTIVETo summarize the complications and the early clinical effect of less invasive stabilization system and the femoral condylar support plates in the treatment of AO type C distal femoral fractures.

METHODSFrom September 2007 to February 2012, 46 patients with AO type C distal femoral fractures were retrospectively studied. Of all patients 25 were treated with less invasive stabilization system including 14 males and 11 females with a mean age of (56.3±4.2) years old; according to AO classification, there were 14 cases of C1, 8 cases of C2 and 3 cases of C3 with a mean hospital stay of (15.6±1.7) days. While 21 cases were treated with femoral condylar support plates fixation including 12 males and 9 females with a mean age of (53.8±5.1) years old;there were 13 cases of C1, 6 cases of C2 and 2 cases of C3 with a mean hospital stay of (17.8±2.2) days. Comparative analysis was performed from the operation related index,postoperative complications and Evanich score of the knee joint function between the two groups at follow-up.

RESULTSAll 46 patients were followed up from 13 to 38 months with a mean time of 19.6 months after surgery. Complications included 1 case with infection,3 cases with internal fixation failure, 1 case with nonunion and 1 case with activity limitation of the affected knee. The differences in the incision length, blood loss, fracture healing time were significant between two groups (P<0.05), while there was no significant difference in the duration of operations, hospital stays and the incidence of postoperative complications between two groups (P>0.05). The statistical significance was also found in the Evanich score at last follow-up between two groups (P<0.05).

CONCLUSIONPatients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time and better functional recovery. Less invasive stabilization system had became one of the ideal internal fixations in the treatment of AO type C distal femoral fractures.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.

BACKGROUND:Adenovirus, expressing within a limited period, can limit the expression time and amount of target genes that is not conducive to ongoing experiments. Here, we select adenovirus as vectors for genetic recombination with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (Trail) gene fragment.
OBJECTIVE:To explore the construction of recombinant lentiviral vector carrying Trail in rats
METHODS:The Trail gene was obtained:according to GenBank in rat Trail gene sequence (NM_145681.1), we designed the gene specific primers of Trail-Age I-F and Trail-AgeI-R, and used AgeI as enzyme cutting site. PCR was applied to amplify Trail gene from rat cDNA Library and construct recombinant plasmids after cutting Trail gene to be cloned into expression vector GV218 by AgeI. Recombinant plasmids were transfected into 293T cells by Lipofeetamine2000 encapsulated recombinant plasmid and auxiliary packaging carrier. The Trail protein of lentiviral plasmids was expressed. Fol owing virus col ection, we identified virus titer and extracted protein from cells to detect Trail expression by western blot assay.
RESULTS AND CONCLUSION:Screened positive Escherichia coli DH5a competent cells were sequenced with 861 bp, which was consistent with Trail nucleotide sequence in GenBank. After transfection 2 days, virus liquid was col ected and confirmed as recombinant plasmid including Trail gene by PCR and Trail proteins expressed in 293T cells by western blot assay. Hole dilution method and real-time fluorescent quantitative PCR determination showed that the virus titer was 2×109 TU/mL. In this study, recombinant lentiviral vector carrying Trail is successful y constructed by homologous recombination in Escherichia coli.
