Using bioactive compounds 7-hydroxy flavone, salicylaldehyde, cinnamic acid and 4-amino-5- mercapto-1,2,4-triazoles as starting materials, three new types of flavone derivatives containing 1,2,4-triazole structure were synthesized via different step reactions. These new compounds were characterized by 1IHNMR, ESI-MS, IR and elemental analysis. Their scavenging effects on the superoxide radical (O2·-), hydroxyl radical (·OH), DPPH · radical and their total reduction activities were tested. The results showed that all of the compounds possessed some antioxidative activity at the concentration of 0.5 mg · mL(-1), but the scavenging ability of the target compounds was lower than that of the standard compound Vc.

Objective To explore the ultrasonographic, clinical and histopathological characteristics features of primary uterus lymphoma. Methods The clinical, sonographic and histopathological characteristics of nine patients who were pathologically comfirmed as primary uterus lymphoma were analyzed. Results Among the nine cases of primary uterus lymphoma, three lesions were found in the uterine bodys and 6 were found in the cervixes. Two patients with uterine body lymphoma had painless pelvic masses and six patients with cervix lymphoma had contact bleeding, including irregular vaginal bleeding in four patients. In sonograms, six lesions showed remarkable hypoechogenicity with homogeneous internal echogenicity;the margins of most lesions were circumcribed;all lesions had posterior enhancement. In color Doppler lfow imaging, abundant vascularities were detected in eight lesions. In the cases of uterine body lymphoma, all of the uterine bodys showed diffuse symmetrical enlargement without disruption of the endometria, while in ifve cases of cervix lymphoma, the tumors showed the shape of lobule. The pathological examination showed that all tumors were diffuse B-cell type non-Hodgkin lymphoma. Conclusions Primary uterus lymphoma has some clinical and ultrasonic features, including contact bleeding or irrgular vaginal bleeding, diffuse symmetrical enlargement of uterine body, complete endometria, remarkable hypoechogenicity, homogeneous echogenicity and posterior enhancement. Final diagnosis depends on the histopathology.

Objective Study the ideal drug to treat age depen de nt epileptic ncephalopathy (ADEE) in earlier period. Methods fi fty-four patients with ADEE were studyed.21 cases used with single topiramate(T PM) as initial treatment and 27 cases used with TPM and antiepileptic drug(AEDs ) .Results Seizure was fully controlled in 11 patients with TPM m onotherapy and in 4 patients with TPM as adjunction.The differences was signif icant(P

Objective To investigate the influence of preemptive analgesia with Hydr- omorphone Hy-drochloride on postoperative cognitive function and inflammation cytokines in the elderly patients. Methods Ninety ASA I orⅡ elder patients were randomly divided in control group (C)and Hydromorphone Hydrochloride group(H) with 45 cases each. Hydromorphone Hydrochloride 2 mg was injected iv before induction of anesthesia in group H. Observed plasma concentrations of the CRP、 TNF-α and IL-6 at different time. Cognitive function was assessed by minimental state examination. Results Plasma the CRP、 TNF-a and IL-6 concentrations were lower and MMSE scales were higher in group H than in group C. Conclusion Preemptive analgesia with Hy-dromorphone Hydrochloride 2 mg can reduce the incidence of postoperative cognitive dysfunction in the elderly patients.

0.05). In the fever experiment,the two kinds of HJD in different doses showed antipyretic effect to various degrees,but the dispensing granule decoction of HJD had the better effect,and the effect in the middle-and high-dose groups was superior to that of the low-dose groups (P

Background and purpose:miR-22 has been reported to be down-regulated in gastric cancer, lung cancer, colorectal cancer, and breast cancer. However, its expression in glioma was still poorly known. This study aimed to explicit whether miR-22 suppresses cell proliferation by targeting MTDH, thus to reveal molecular mechanism that miR-22 functions as a tumor suppressor in glioma. Methods:Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted for detecting the expression of miR-22 in gliomas and normal brain tissues. MTDH 3’UTR-luciferase vector was constructed and dual-luciferase reporter gene assay was employed to examine the effect of miR-22 on luciferase activity. U251 cells were transfected with miR-22 mimics, and MTDH siRNA as for postive control, then Western blot was performed to detect the expressions of MTDH protein. The proliferation ability of U251 cells was evaluated by MTT assay. Results:miR-22 was down-regulated in glioma tissues. Glioma patients with relatively high expression of miR-22 showed lower mortality compared with low expression of miR-22 by using Kaplan-Meier survival curves. We demonstrated miR-22 could bind to the 3’ untranslated region (UTR) of MTDH and inhibited the luciferase activity. Western blot showed that the expression of MTDH protein was inhibited by restored miR-22 or siR MTDH in U251 cells. Overexpression of miR-22 or siR MTDH inhibited the proliferation of U251 cells. Conclusion:miR-22 suppresses cell proliferation by targeting MTDH in glioma.

OBJECTIVETo observe the clinical effect of Ziyin Huoxue Granule (ZHG) combined glucocorticoids and antibiotics in treatment of radiation pneumonitis.

METHODSTotally 70 radiation pneumonitis patients were assigned to the treatment group and the control group according to random digit table, 35 in each group. All patients received glucocorticoids and antibiotics. Patients in the treatment group additionally took ZHG, one dose per day for 4 successive weeks. Watters clinical-radiologic-physiologic (CRP) score, Karnofsky Performance Status Scale (KPS) , and acute radiation injury classification [set by Radiation Therapy Oncology Group (RTOG)] were observed in the two groups before and after treatment. The application time for antibiotics and glucocorticoids was compared between the two groups.

RESULTSAll patients completed this trial, and nobody dropped out or died. There was no statistical difference in Watters-CRP scores, KPS, or RTOG between the two groups before treatment (P > 0.05). Compared with before treatment in the same group, RTOG classification was obviously improved in the two groups (P < 0.05). Compared with the control group, Watters-CRP scores decreased, KPS increased, the application time for antibiotics and glucocorticoids was reduced (P < 0.05). The efficacy of RTOG classification was better in the treatment group than in the control group, but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONZHG combined glucocorticoids and antibiotics was superior in treating radiation pneumonitis to using glucocorticoids or antibiotics alone in elevating Watters-CRP scores, shortening the application time for glucocorticoids and antibiotics, and improving patients' physical conditions.
