1.Advance in glutathione S-transferase kappa 1
Journal of Central South University(Medical Sciences) 2017;42(4):468-475
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 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 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.

Objective To evaluate the efficacy and safety of sunitinib in patients with metastatic renal cell carcinoma. Methods Twenty-three male patients and 8 female patients were included in this study.All patients were metastatic renal cell carcinoma with prior radical nephrectomy or biopsy.Patients received treatment with sunitinib in repeated 6-week cycles,consisting of 4 weeks of 50 mg daily sunitinib administration followed by 2 weeks off treatment(schedule 4/2).CT scan was used to evaluate the efficacy every 2 cycles. Results Twenty-four of the patients could be evaluated the efficacy.None of them achieved complete responses,5 achieved partial responses,15 were in stable and 4 were with disease progression including 1 death.Four patients were forced to stop treatments because of poor general condition,lack of financial support or hepatic injury.Three cases could not be evaluated because of no long enough follow-up.The objective response rate was 21%(5/24)and disease control rate was 83%(20/24).The common adverse effects included hand-foot syndrome,diarrhea,anorexia,stomatitis,hemorrhagic tendency and hematotoxicity.But almost all of them were curable by using adjuvant drugs. Conclusions Sunitinib is efficient in the treatment of metastatic renal cell carcisoma.Most of the side effects are tolerable or curable.
