Agonists of peroxisome proliferator-activated receptor gamma (PPARgamma) are of interest as a treatment of type II diabetes, and indenone derivatives are a new class of non-TZD PPARgamma agonists. Based on existing indenone derivatives, a series of novel ones have been designed and synthesized. Meanwhile the structures have been comfirmed with 1H NMR and MS. Among them, 17b and 19 showed higher agonistic activities than rosiglitazone.

MicroRNAs (miRNAs) negatively mediate the post transcriptional target genes by degrading mRNAs and inhibiting translation of protein.Deregulation of miRNAs are directly or indirectly correlated with tumorigenesis and development of cancer.Currently,the application of miRNAs as a non-invasive potential biomarker with high stability is under investigation.

The morbidity of young non-small cell lung cancer(NSCLC)increases in the recent years.Young group patients should be defined as age under 40 years old.The risk factors of etiology in the young NSCLC may be related with smoking,genetic predisposition,Internal and external environment factors havoc and etc.There is no specific symptoms of young NSCLC,therefor,it happens misdiagnosis and harder to be confirmed.The morbidity in young female group of NSCLC patients is higher than aged patients.The most frequent histopathologic type is adenocarcinoma and the ratio of advanced stages with low differentiation has been found to be more common.The chances of surgery seems lower than others.EGFR gene mutation percentage in the young NSCLC maybe lower than that in the old patients,while the positive mutation of MEL4-ALK gene maybe more prevalent in the young patients.The prognosis of young NSCLC seems to be poor with lower tumor progression time of the first line therapy.Better prognosis of young NSCLC patients maybe achieved by early diagnosis and efficient therapy according to the accurate genotypes.

Objective To observe the correlation between platelet parameters , platelet activation marker and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitus. Methods One hundred and ninety-five type 2 diabetic patients were enrolled in this study. The patients were divided into the normal control group, the CIMT increased group and the clot group according to the carotid intima-media thickness. Levels of platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), platelet hematocrit(PCT), urinary 11-dehydro-thromboxane B2 (11-DH-TXB2) and other clinical, biochemical characteristics were measured. Results (1) Levels of serum LDL-C, MPV, PDW, urinary 11-DH-TXB2 and clinical course in the clot group were higher than those in the CIMT increased group and the normal control group (P < 0.05). (2) Compared with the normal control group, the clinical course, serum LDL-C, MPV, PDW and urinary 11-DH-TXB2 were higher in the CIMT increased group (P < 0.05). (3) By using with spearman rank correlation test, carotid intima-media thickness was positively associated with age , course , BMI , GLU , GHbA1C , LDL-C , MPV , PDW and urinary 11-DH-TXB2, whereas carotid intima-media thickness was negative associated with HDL-C, PLT (both P < 0.05). (4) MPV, PDW and urinary11-DH-TXB2 were shown as the independent risk factors for CIMT. Conclusions Platelet activation marker and platelet parameters are associated with carotid intima-media thickness in patients with type 2 diabetes mellitus.

Aim To investigate the cytotoxic activity of HDAC inhibitor Trichostatin A (TSA)combined with anticancer drugs targeting DNA on T24 bladder cancer cell line.Methods MTT assay was used to detect the inhibitory rate of TSA alone or combined with ADM, MMC and DDP respectively on T24 bladder cancer cell in cancer cell proliferation by administering TSA alone or combined with ADM, MMC and DDP respectively.Jin′s equation was used to evaluate the efficacy of drug combination. Results The growth inhibitory rate of TSA combined with ADM, MMC and DDP respectively was in a concentration-dependent manner. The synergism of TSA combined with MMC was most significant. When administered in lower or moderate concentration, TSA combined with ADM or DDP in lower or moderate concentration demonstrated synergic effect too.Conclusion HDAC inhibitor TSA enhances the cytotoxic activity of anticancer drugs targeting DNA on bladder cancer cells and is promising to be used in chemotherapeutic regimens for advanced bladder cancer.

Objective:To investigate the effect of continuous blood purification (CBP) on inflammatory factors and immune function in patients with sepsis,in order to provide reference for clinical treatment of sepsis.Methods:A total of 76 patients with severe sepsis,who were treated in ICU of Daqing Oilfield General Hospital from June 2014 to December 2016,were selected.The patients were divided into conventional group (n=36) and CBP group (n=40) according to the received treatment method.The patients in the conventional group were treated with targeted therapy and life support,while the patients in the CBP group were treated with CBP on the basis of targeted therapy.The levels of interleukin-6 (IL-6),interleukin-10 (IL-10),tumor necrosis factor-α (TNF-α) and C reactive protein (CRP) of the patients in the two groups were detected and compared before treatment and after 3d of treatment.The CD3+,CD4+,CD8+T cell and the CD4+/CD8+ ratio before treatment and after 3 d of treatment were calculated and compared between the two groups.Results:There was no significant difference in the level of serum inflammatory factors between the two groups before treatment (P＞0.05).The levels of serum inflammatory factors in the two groups were significantly decreased after 3 d of treatment,and the levels of IL-6,TNF-α and CRP in the CBP group were significantly lower than those in the conventional group (P＜0.05).There was no significant difference in immune function indexes between the conventional group and the CBP group before treatment (P＞0.05).After 3d of treatment,CD3+,CD4+ and CD4+/CD8+ ratio were significantly increased in the two groups,and the CD4+ and CD4+/CD8+ ratio of the CBP group were sig-nificantly higher than those of the conventional group (P＜0.05).Conclusion:The application of CBP in the treatment of patients with sep-sis can obviously improve the expression of inflammatory factors of patients,and can improve the immune function and promote the re-covery of immune function.

Objective To study the clinical value of tamsulosin in prevention of urinary retention after radical hysterectomy.Methods Sixty-six patients after radical hysterectomy were enrolled in this study, and divided into two groups in random.Thirty-three cases in the treatment group were treated with tamsulosin 0.2 mg once every night,3 days before the catheter was drawn.While 33 cases in the control group only with placebo.Catheter keeping days, residual urine volume at first extraction,the rate of urinary retention and urinary tract infection,hospitalization time and drug adverse reaction were compared in two groups.Results Catheter keeping days and hospitalization time were shorter in the treatment group than those in the control group(P< 0.05).The residual urine volume at first extraction was(38.2 ± 5.6) ml in the treatment group and (168.5 ± 11.8) ml in the control group,there was significant difference between two groups (P< 0.05).The rate of urinary retention was 18.2%(6/33) in the treatment group and 36.4%(12/33) in the control group,there was significant difference between two groups (P <0.05).There was no adverse reaction resulted from tamsulosin in the treatment group.Conclusion Tamsulosin is an effective drug which could prevent and treat the urinary retention after radical hysterectomy.

Objective To investigate the clinical efficacy and side reaction of brucea javanica oil ( BJO) combined with 125I and chemotherapy on stageⅢ?Ⅳpatients with non?small cell lung cancer ( NSCLC) . Methods One hundred and twenty cases on stageⅢ?Ⅳpatients with NSCLC were randomly divided into two groups,60 cases received BJO combined with 125I and chemotherapy treatment(observation group),the other 60 cases received 125I combined with chemotherapy treatment(control group). Results The objective response rate(ORR) and disease control rate (DCR) were 71. 7%,86. 7% of observation group and 66. 7%,85. 0% of control group,there were no significant difference(χ2=0. 352,0. 069;P>0. 05) . The improvement rate of KPS score in observation group was significantly superior to that in control group, the difference was significant (76. 7% vs. 55. 0%;χ2=6. 261,P<0. 05) . The incidence of myelosuppression and gastrointestinal adverse e?vents in observation group was significantly lower that in control group ( 68. 3% vs. 83. 3%,41. 7% vs. 61. 7%;χ2=3. 883,4. 805;P<0. 05) . Conclusion BJO combined with 125I and chemotherapy for treating on stageⅢ?Ⅳ patients with NSCLC can reduce the toxicity and side effects caused by chemotherapy,and significantly im?prove the clinical symptoms and quality of life of patients.

Objective To investigate the correlation between three gene locus polymorphisms of X-ray repair cross-complementary protein 1 (XRCC1) exon (Arg194Trp, Arg280His and Arg399Gln) and the risk of colorectal cancer (CRC). Methods A case-control study was performed in 250 CRC patients (case group, 128 colon cancer patients and 122 rectal cancer patients) and 213 healthy individuals (control group). The three gene locus polymorphism of XRCC1 was tested by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. The genotype distribution and allele frequency of each locus was analyzed with SPSS 10.0 software. Results There was no significant difference in allele frequency of XRCC1 at 194 and 399 loci (P > 0.05). However, the 280 Arg/His allele frequency of XRCC1 was higher in case group than that in control group (OR=1.66,95%CI:1.01~2.73,P=0.047). The 280Arg/His allele frequency was higher in rectal cancer group than that in control group (OR =1.82,95%CI:1.02~3.27). The frequency of 280His allele (Arg280His and His280His) was higher in case group than that in control group (OR=1.85,95%CI:1.06~3.22). However, it was a relative low risk factor of colon cancer and there was no significant difference between colon cancer group and control group (OR=1.85, 95%CI:1.06~3.22). Conclusions There was no correlation between XRCC1 Arg194Trp and Arg399Gln polymorpohisms and the risk of CRC. However, 280Arg/His genotype may increase the risk of CRC, and 280His allele is a risk factor of rectal cancer.
