Glutathione S-transferase kappa 1 (GSTK1) is a key regulator for adiponectin secretion and multimerization.In Caenorhabditis elegans,GSTK1 is involved in energy production and lipid metabolism.Meanwhile,the GSTK1 level is negatively correlated with obesity.It may alleviate the endoplasmic reticulum stress-mediated downregulation of adiponectin.Moreover,a polymorphism in human GSTK1 promoter is related with insulin secretion and fat deposition.Therefore,GSTK1 might be a novel target for the treatment of insulin resistance and the relevant metabolic diseases.

To prepare large naive phage antibody library, the host bacteria with high transformation efficiency is used in the Cre-LoxP recombination system. The variable regions of immunoglobulin light and heavy genes were amplified from lymphocytes collected from adult peripheral blood and newborn cord blood. The genes were spliced to form the single-chain variable fragments (scFv) by overlap PCR, cloned into pDAN5a vector and then transformed into XL2-blue MRF' with the Hte gene. Compared with XL1-blue strain, the size of the primary library was increased by 3.9 times. The primary library infected Cre recombinase-expressing bacteria, and the genes between phagemids created many new VH/VL combinations. The library was calculated to have a diversity of 1.7 x 10(11) and validated by the selection of antibodies against six different protein antigens. This library provides the basis for further selection of antibody-based drugs. It is the first time to report that XL2-blue MRF' can be used to improve the diversity of the library in the recombination system.

Objective To investigate the effect of flow management of cerebral perfusion during aortic arch surgery on the neurological complication.Methods From March 2007 to November 2011,189 patients underwent aortic arch surgery with hypothermic circulatory arrest plus antegrade cerebral perfusion in our department.The clinical data were analyzed retrospectively.According to the different methods of cerebral perfusion flow nanagement,patients were divided into two groups.Single pump with double limb (to the lower body and brain) perfusion was used in group A (96 patients),based on natural distribution of petfusion flow without control.Modified flow management was used in group B (93 patients).A magnetic flow sensor probes was installed on the brain perfusion limb to monitor and control the cerebral perfusion flow precisely (10 ml · kg-1 · min-1).Postoperative neurological complications were compared between two groups.Results There was no significant difference between the two groups in CPB time,aortic clamping time and circulatory arreating time.However,the morbidity of postoperative neurological complications in group B was much lower than that in group A (1.1％ vs 5.2％,P ＜0.05).Conclusion When performing antegrade cerebral perfusion during aortic arch surgery,precisely control of cerebral perfusion flow can reduce the morbidity of postoperative neurological complications effectively.

With the development of therapeutic antibodies over the past decade, they have become the treatment options for immunity and inflammation diseases. Major limitations of mouse antibodies as therapeutic agents - immunogenicity, lack of effectors' functions and short serum half-life -- were subsequently identified and largely overcome by the advent of humanized and fully human antibody technologies. The therapeutic antibodies for immunity and inflammatory diseases are primarily utilized in the treatment of allograft rejection, autoimmune disease, autoinflammatory syndromes, allergies and other chronic inflammation. The action mechanisms of therapeutic antibody include blocking ligands or receptors, regulating receptor activity, clearing the target cells or activating receptor. Strategies for generating the antibody drugs with high efficacy and low side effects can be realized by modulation of Fc-mediated activities and optimization of antigen-binding domains.

Obejctive To compare the differences between conventional radiation therapy (3DCRT) and intensity modulated radiation therapy( IMRT) for locally advanced laryngeal carcinoma patients by ECLIPSE treat -ment planning system.Methods Six locally advanced laryngeal carcinoma patients ′treatment plans were de-signed as IMRT and 3DCRT according to ECLIPSE treatment planning system ,respectively.The following values were measured,such as V95%、D5%、D95%、Dmin and D mean of the target volume,and the D50,D33,D5, Dmax and Dmean of normal tissues.Results The dose coverage rate of GTV and GTVnd in the IMRT plan was compared to ECLIPSE treatment planning system with no statistical differences.However, there were obvious difference in CTV and some normal tissues.Conclusion Both IMRT and 3DCRT have good coverage to primary tumor and metastatic lymph nodes.IMRT can spare the parotid from high dose irradiation.

OBJECTIVE:To provide reference for the standardization of package insert of common drugs for elderly patients. METHODS:Outpatient prescriptions in our hospital from 2013 to 2014 were collected,and common drugs of elderly patients(≥60 years old)were ordered by consumption sum,and package inserts of top 100 drugs were statistically analyzed for absent items. RESULTS:The 100 common drugs for elderly patients included 28 Chinese traditional drugs and 72 chemical drugs. The Chinese traditional drug had more absent items,mostly were pharmacokinetics and drug overdose(92.9%),medication of elderly patients (85.7%),drug interactions(78.6%)and pharmacological actions(50.0%);the proportion of contraindications(16/28),adverse re-actions(15/28) and precaution(9/28) with uncertainty was relatively high. Items of chemicals package insert were better than Chi-nese traditional drug,absent items were pharmacokinetics and drug overdose(5.6%),medication of elderly patients and pharmaco-logical actions (2.8%) and drug interactions (1.4%);the proportion of medication of elderly patients (16/72),drug interaction and drug overdose(12/72)with uncertainty was relatively high. CONCLUSIONS:The common problem existing in the drug manu-al is characterized by absence of usage for elderly,drug descriptions is not clear,etc. Package inserts should be further improved to strengthen its standardization.

OBJECTIVE:To evaluate the current status and future trend of antibacterials utilization in our hospital.MET-HODS:A retrospective analysis was conducted on the use of antibacterials in our hospital in 2003～2005,covering sales value and application density(AD).RESULTS:Antibacterials as used in our hospital had been high in AD for the three years.In ran-ked order,the top three subcategories were quinolones,macrolides and lincosamides,represented respectively by levofloxacin,azithromycin and clindamycin.CONCLUSIONS:Antibacterials as used in our hospital are high in AD.Administration of antibacterials use during the perioperative period should be specially strengthened to avoid irrational combination medication.

Objective To explore the value of brainstem auditory evoked potentials (BAEP) in the evaluation of spastic cerebral palsy (CP). Methods Forty five cases of CP children were recruited and divided, according to the diagnosis standards, into three groups: diplegia, hemiplegia and tetraplegia groups. Twenty three healthy children served as control. BAEP was recorded from all the subjects and comparisons were done among the various groups. Results The abnormality rate of BAEP in the hemiplegia and tetraplegia groups was significantly higher than that in the diplegia group ( P

Objective: To identify Persicae Semen and its sibling species, and to secure the quality and clinical safety of this medicinal material. Methods: The internal transcribed spacer 2 (ITS2) of nuclear ribosomal DNA of Persicae Semen and its sibling species were amplified and bidirectionally sequenced by DNA barcoding. Sequence assembly and consensus sequence generation were performed by the CodonCode Aligner 4.1. The genetic distances were computed by MEGA 5.0 in accordance with the Kimura 2-parameter (K2P) model, and the phylogenetic tree constructed by the neighbor-joining (NJ) method. Results: The length of ITS2 sequences of the two origin plants of Persicae Semen was between 212 bp to 213 bp. Their intraspecific genetic distance was much lower than the interspecific genetic distance with their sibling species. The ITS2 sequence possessed the character of good stability and low intra-specific sequence variation. In the NJ tree, both Prunus persica and P. davidiana were clustered into one large branch, and clearly separated with their sibling species. Conclusion: ITS2 can be used to effectively distinguish Persicae Semen from its sibling species, which can provide a reference for the iden-tification of other Chinese medicine and its sibling species.
