Objective To discuss the CT diagnosis and differential diagnosis of lumbar posterior marginal intraosseous cartilaginous nodes(LPMN)and the possible pathogenesis.Methods CT manifestations of LPMN in 29 cases hospitalized in the last three years were analysed retrospectively.Results The mainly CT features of LPMN included:(1)Osseous defect with sclerotic margin in the posterior-superior or posterior-inferior margins of centrum;(2)Behind the defect area,bone fragments protrude into the spinal canal,totally dislocated or partially joined with centrum;(3)The dural sac and nerve root compressed accompanied by lumbar disc herniation and spinal canal stenosis.Conclusion LPMN can be definitively diagnosed by CT scan,which provides reliable basis for the treatment project.

Objective To observe the clinical efficacy of treatment of diabetic nephropathy with Shuxuening injection combined with benazepril.Methods 60 cases from January 2014 to January 2015,were randomly divided into observation group and control group of 30 patients.the control group were given benazepril treatment,observation group were based on Shuxuening injection treatment,patients were followed up and record changes related indicators.Results The urinary β2-MG and hs-CRP were after treatment(0.38±0.08,6.29±1.40)mg/L,than the control group(0.48±0.10,7.74±1.36)mg/L,and the difference was significant sex(P<0.05); after treatment observation group 24H urine protein quantitative detection of(0.69±0.50)g/24h,than the control group(1.04±0.63)g/24h,and the difference was statistically significant(P<0.05); After the observation group patients,low-density lipoprotein,serum creatinine value were(359.2±50.3mg/L,2.40±0.63mmol/L,95.6±22.3mol/L),were better than the control group(379.8±48.3mg/L,3.44±0.76mmol/L,108.5±34.2mol/L),and the difference was statistically significant(P<0.05); observation group total effective rate was 90.0％,higher than 73.0 percent,and the difference was statistically significant(P<0.05).Conclusion Shuxuening injection combined with benazepril clinical treatment of diabetic nephropathy exact,no significant side effects,is worthy of further research and application.

Objective To investigate the effect of UCP2 on cell proliferation, apoptosis, metastasis in cervical squamous carcinoma. Methods Plasmid?mediated downregulation of UCP2 was obtained in cervical cancer cell lines. MTT, flow cytometry and transwell chamber assay were conducted to detect the ability of proliferation, apoptosis and metastasis. Characteristics of UCP2 protein was analyzed by bioinformatics methods. Results (1)UCP2 was verified to be downregulated by qRT?PCR and Western blotting assay.(2)MTT, apoptosis assay and transwell chamber assay showed that the proliferation of SiHa cell was significantly inhibited, and the apoptosis rate was significantly increased, and metastasis was markedly deduced (P < 0.05). (3) Bioinformatic analysis showed that UCP2 was located in mitochondria with several phosphorylation sites, and UCP2 interacted with other proteins to produce biological effects. Conclusion UCP2 may play an important role in the occurrence and development of cervical cancer, and it is expected to be a new target for the early diagnosis and treatment of cervical cancer.

Aim To investigate the effect of selective cyclooxygenase-2 inhibitor, NS-398, on cell apoptosis in leukemia cell line K562 cells and its underlying mechanism. Methods Apoptotic cell percentage was examined by flow cytometry(FCM). The protein expression of Bcl-2 and Caspase-3 was detected by Western blot, and the activity of Caspase-3 was checked by FCM. Results NS-398 induced the cell apoptosis in K562 cells in a dose-dependent manner. After NS-398 treatment, the expression of Bcl-2 protein was downregulated, whereas the expression of Caspase-3 protein was upregulated. Moreover,the activity of Caspase-3 was increased in a dose-dependent way after NS-398 treatment. Conclusion Selective cyclooxygenase-2 inhibitor,NS-398,significantly induced apoptosis in K562 cells. The underlying mechanism might be related to the downregulation of Bcl-2 and the activation of Caspase-3.

To assess the expression of peripheral blood CD62P in patients with non-small cell lung cancer and its clinical significance, peripheral blood CD62P content in 75 patients with lung cancer was detected by immune-flow-cytometry. Among them 45 patients with lung cancer were subjected to comparison of the CD62P contents between pre-operation and post-operation, and comparison with those of 30 normal donors. The results showed that peripheral blood CD62P content in patients with lung cancer was significantly higher than that in normal con-trols(P

Aim To investigate the effect of Trichostatin A(T SA)on histone deacetylase (HDAC1) and P21 WAF1/CIP1,cyclin dependent ki nase inhibitor,in NB4 cells for exploring the underlying mechanism of TSA in an ti-leukemia.Methods The total proteins and P21 WAF1/CIP1 mRN A were extracted from acute promyelocytic leukemia NB4 cells treated with or wit hout TSA of different concentrations at different time points,Western blot anal ysis was performed to determine the level of HDAC1 and P21 WAF1/CIP1 protei n,respectively,and RT-PCR was performed to detect the level of P21 WAF1/CI P1 mRNA.Results (1)The level of HDAC1 was obviously inhibited by TSA,and had decreased at 4 hours at IC 50 and lasted for 48 h. The inhibi tion of HDAC1 was significant at the TSA concentration of 37.5 nmol?L -1 , but there was no difference between 75~300 nmol?L -1.(2)The levels of P21 WAF1/CIP1 mRNA and protein were up-regulated by TSA in dose-and ti me-dependent manner,and mRNA increased in 8 h,but the P21 WAF1/CIP1 prot ein was detected at 12 hours and lasted for 48 hours.Conclusion TSA could inhibit the level of HDAC1 and enhance the expression of P21 WAF1/CIP1 protein and mRNA,and the results suggest that inhibiting HDAC1 and increasin g P21 WAF1/CIP1 may be one of the possible mechanisms of anti-leukemia by TSA.
