AIM:To compare the mutant prevention concentration(MPC)of linezolid and vancomycin against methicillin resistant staphylococcus aureus(MRSA)and study the correlation between minimal inhibitory concentration(MIC)and MPC.METHODS:MICs and MPCs of two drugs against 35 MRSA clinical stains were determined by agar plates dilution method.The correlations between MIC and MPC were determined by linear regression.The ability to restrict the resistance was evaluated according the pharmacokinetics of two drugs.RESULTS:The MPCs of two drugs against MRSA were 16 and 8 ?g/mL and the MPC/MIC was 8.MPCs and MICs correlated poorly(R2 were 0.32 and 0.008,respectively).According to pharmacokinetics of two drugs,the concentration of linezolid was inside the MSW(mutant selective window)for the entire dosage interval,while the concentration of vancomycin exceeded the MPC for the most dosage interval.CONCLUSION:The capacity of vancomycin for restricting the selection of MRSA resistant mutants is stronger than that of linezolid.There is low correlation between MPC and MIC.

Objective To investigate the relationship between duration of hypertension and cognitive function in adult hypertension patients.Methods A total of 224 subjects with normal blood pressure were enrolled in group A,and 1 296 patients with poorly controlled hypertension were further divided by the duration of hypertension into group B (≤5 years),group C (6-10 years),group D (11-20years) and group E (＞ 20 years).Face-to-face surveys were conducted in all the subjects by trained physicians using Mini-Mental-State-Examination (MMSE) and Clock-Drawing-Test (CDT).The incidences of cognitive impairment were compared among the five groups and the relationship between duration of hypertension and cognitive function were analyzed by SPSS 18.0 software.Results (1) Compared with the normotensive group,the hypertensive group performed worse in the scores of MMSE,CDTs,the memory type cognitive function and the non-memory type cognitive function (MMSE:Z =-2.585,P =0.010;C DTs:Z =-3.689,P ＜ 0.001 ; memory type cognitive function:Z =-2.718,P =0.007 ; non-memory type cognitive function:Z =-1.994,P =0.046).(2) The incidences of cognitive impairment in the five groups were 3.6％ (8/224),6.6％ (26/393),16.6％ (72/433),19.7％ (55/279) and 33.5％(64/191),respectively.(3) Compared with the group A,the cognitive function was significantly worse in the group E (MMSE:Z =61.314,P ＜ 0.001 ; CDTs:Z =44.642,P ＜ 0.001 ; memory type cognitive function:Z =35.703,P ＜ 0.001 ; non-memory type cognitive function:Z =54.440,P ＜ 0.001).Conclusions Hypertension is a risk factor for the cognitive dysfunction.The incidence of cognitive dysfunction and the severity are positively associated with the duration of hypertension.In those with hypertension over 20 years,the cognitive dysfunction occurs much more obviously.

Polycyclic aromatic hydrocarbons (PAHs), which consist of two or more fused aromatic rings, are ubiquitous pollutants in the environment, and are of concern because of their toxic and carcinogenic poten- tial. In nature, the aerobic bacterial bio-treatment of contamination with PAHs is of the major route. It is ob- vious that the degraders are more useful for the bioremediation of contaminated environments and may be potentially used in a wide of application. Therefore, many researchers have been focusing on the biodegra- dations of PAHs by various aerobic bacteria. In the last two decades, the mechanism of degradation in bacte- ria capable of aero-biotic utilizing PAHs has been well investigated in genetic studies such as diversities of genes of PAHs metabolism, the genes which participate directly in PAHs metabolism and the genetics me- chanism of bacterial population and so on. In brief, most of PAH-catabolic genes are classed into two groups according to their identity. One group is called "the nah-like genes", the other group, i.e. "the nah-unlike genes" is different from the nah-like genes. The different molecular genetics mechanisms of bacterial popu- lation adapted to PAH compound will be dealt with in three groups: (i) point mutations, (ii) gene transfer, and (iii) DNA rearrangements and absentation. In this review, some genetic knowledge about aerobic bacte- ria with the mechanism for the degradation of PAHs is summarized.

BACKGROUND:The incidence rate of peripheral T cel lymphoma is high in Asia, and peripheral T cel lymphoma is aggressive with generaly poor prognosis. However, there is no standard treatment strategy. OBJECTIVE:To retrospectively analyze the therapeutic effect of autologous hematopoietic stem cel transplantation on peripheral T cel lymphoma as wel as relevant toxic and side effects. METHODS:A retrospective review was conducted in 35 patients with peripheral T cel lymphoma who underwent autologous hematopoietic stem cel transplantation from March 2003 to April 2014, including 22 cases of extranodal NK/T-cel lymphoma (nasal type), 1 case of angioimmunoblastic T-cel lymphoma, 8 cases of peripheral T cel lymphoma (non-specific), 3 cases of ALK-positive anaplastic large cel lymphoma, and 1 case of ALK-negative anaplastic large cel lymphoma. Al of 35 patients were classified pathologicaly according to WHO pathological type in 2001 and 2008, and received the high-dose chemotherapy with vincristine, cytarabine, etoposide, mitoxantrone, semustine, cyclophosphamide, and total body irradiation. RESULTS AND CONCLUSION: After a median folow-up of 54 (9-120) months, the probabilities of overal survival and disease-free survival after transplantation were 80% (n=28) and 71% (n=25), respectively. Eight cases (23%) relapsed after transplantation, seven of which died. It was safe with mild and moderate transplantation related side-effects on opportunistic infections, oral cavity mucosa and bladder responses and so on, and there were no severe, life-threatening late complications. Autologous hematopoietic stem cel transplantation may be an effective and safe treatment for peripheral T cel lymphoma, and there is a better benefit in peripheral T cel lymphoma patients with first complete remission.

Objective To approach curative effect of using DLI +IL-2 as immunobiotherapy after Mixed-HSCT in acute myelogenous leukemia.MethodAfter times of chemotherapy,8 cases of patients with acute myelogenous leukemia received Mixed-HSCT,then were treated with DLI +IL-2 for 2-7 times.Observed clinical effect for 1 to 5 years.Result DFS in 8 cases of patients with acute myelogenous leukemia received Mixed-HSCT and treated with DLI +IL-2 for 2-7 times were 62.5%.There were no GVHD.Conclusion Immuno-biotherapy with DLI +IL-2 after Mixed-HSCT in patients of acute myelogenous leukemia may be a method to increase DFS efficiently.

Objective To explore the survival mechanism of hippocampal ne urons after damage of hypoxia-ischemia and reperfusion of brain.Methods Seven days old SD rats(n=56) were randomly divided into hypoxia-ischemia br a in iniury(HIBD) group and sham group.The HIBD and reperfusion model was establis hed.The flowing of blood was de tected by multicolor Doppler.The p-CREB(phosphorylated c-AMP response element bi nding protein)and c-Jun were immunohistochemically evaluated in hippocampus.Thi onin staining was used to observe the apoptosis.Results The expression of p-CREB reache d the peak at 3,24 h postreperfusion in the right hippocampus of HIBD group,and then decreased to the normal level on the 7th day.In contral group the same reg ions showed basic immn-noreactivity.While c-Jun reached the peak at 6 h postreperfusion,then with a slightly decrease at 24 h;and at 48 h the other peak appeared,then with a gradual decline .On the 7th day the mumber of positive cells were still significanthy more than control group(P0.05).The sham animal showed very few apoptosis cells in the regio ns of hippocampus.Conclusions The persistent activation of CREB in the hippocampus regulates,the expression of c-Jun through the signal transductions and is involved in the course of neuron s′ survival and repair during the period of post hypoxia-ischemia reperfusion.I t is very important for the protection of the pyramidal hippocampal neurons on t he damaged side,especially for the sensitive region CA1.

Most main oilfields in China have already entered a "double high" development stage (high water cut, high recovery degree). To further enhance oil recovery in reservoirs after polymer flooding (RAPFs), an efficient activator formulation for promoting metabolism of endogenous microorganism was studied by aerogenic experiments, physical simulation experiments, electron microscopy scanning and pyrophosphate sequencing. Results show that the activator could activate the endogenous microorganisms in the injected water and make the pressurized gas reach 2 MPa after 60 d static culture of the activator in a high pressure vessel. The oil recovery efficiency of natural core physical simulation flooding can be improved by more than 3.0% (OOIP) in RAPFs when injected 0.35 PV activator with 1.8% mass concentration, and a lot of growth and reproduction of activated endogenous microorganism in the core was observed by electron microscopy scanning. Field trial with 1 injector and 4 producers was carried out in the east of south II block of Sa Nan in December 2011. By monitoring four effective production wells, changes of carbon isotope δ13C (PDB) content of methane and carbon dioxide were -45 per thousand to -54 per thousand and 7 per thousand to 12 per thousand. Compared with east II of Sa Nan block, the oil amount increased by 35.9%, water cut stabled at 94%. The incremental oil was 5 957 t during the three and a half years, which provides an alternative approach for further improving oil recovery in similar reservoirs.
