An HPLC method was established to simultaneously determine the five sesquiterpene lactones, carabrone, carabrol, 2-desoxy-4-epi-pulchellin, telekinand 11(13)-dehydroivaxillin in Carpesium abrotanoides. Samples were analyzed on a kromasil C18 column (4.6 mm x 250 mm, 5 µm); mobile phase: A was acetonitrile, B was water, with gradient elution; flow speed: 1.0 mL · min(-1); detection was carried out using a photodiode array detector at 211 nm; temperatureof column: 30 °C. The five sesquiterpene lactones were well separated with good linear correlations in the range of 0.270-2.700 (r = 0.999 7 ), 1.336-13.360 (r = 0.999 6), 0.258-2.580 (r = 0.999 7), 0.238-2.380 (r = 0.999 9), 0.490-4.900 µg (r = 0.999 9) for carabrone, carabrol, 2-desoxy-4-epi-pulchellin, telekin and 11 (13) -dehydroivaxillin. The average recoveries of these five sesquiterpene lactoneswere 96.78%-98.41% (RSD 1.3%-2.9%). The method was simple, repeatable and stable, which could be used for quality control of C. abrotanoide.

Objective To assess the clinical value of 18F -FDG PET/CT in the diagnosis of primary, suspected recurrent and metastatic cervical cancer.Methods The results of 67 women who were suspected suffering from cervical cancer had undergone Color dopplar ultrasound,HPV,TCT,some of them do CT,MRI and SCC -Ag examination from April 2013 to April 2015 were retrospectively analyzed.Their 18F -FDG PET/CT images with the other test results were compared.The presence or absence of tumor was confirmed by histopathology.Results In the 67 patients,22 cases were finally diagnosed as primary cervical tumors,and 22 cases of recurrent and metastatic cervical tumors.In all the patients with cervical cancer,18F -FDG PET/CT found a total of 41 cases,which had contributed to the diagnosis in 94.0%,But 3 cases had not been found.For the detection of primary cervical tumors, 18F -FDG PET/CT was diagnostically wrong in 4.2%,For the detection of recurrent and metastatic cervical tumors, 18F -FDG PET/CT was diagnostically wrong in 7.0%,and 2 cervical adenocarcinoma patients were not diagnosed by 18F -FDG PET/CT.Conclusion The study showed a significantly higher sensitivity of 18F -FDG PET/CT for the detection of primary,recurrent and metastatic cervical cancer than the other auxiliary examination.18F -FDG PET/CT for the diagnosis of cervical cancer can be worth popularization.

Objective To observe the effect of Salviae Miltiorrhizae and Ligustrazine Hydrochloride Injection in inauxiliary treatment of ischemic stroke and its clinical efficacy. Methods 142 cases of patients with ischemic stroke, were randomly divided into experimental group and control group. Control group(n=71) were treated with conventional therapy. Test group(n=71) were treated with Salviae Miltiorrhizae and Ligustrazine Hydrochloride Injection on the basis of conventional therapy. Hemorheological changes, nerve function improvement and treatment efifcacy in two groups before and after treatment were observed and analyzed. Results After treatment, the plasma viscosity and hematocrit in control group were 1.91±0.35, (49.58±1.04)%; while experimental group were 1.17±0.28, (38.97±1.31)%, the differences between two groups were signiifcant(P<0.05). Before treatment, the neurological function score in control group was 22.49±1.21, while experimental group was 23.18±1.74, there was no signiifcant difference between two groups. After treatment, the neurological function score in control group was 10.58±0.94, while experimental group was 4.62±2.05, the difference was signiifcant(P<0.05). The total effective rate was 80.3%in control group ,while 88.7% in experimental group, the difference was signiifcant(P<0.05). Conclusion The clinical efifcacy of Salviae Miltiorrhizae and Ligustrazine Hydrochloride Injection in auxiliary treatment of ischemic stroke was accurate, and it can alleviate the symptom of patients.

Objective To explore the effects of oxidative stress in the pathogenesis of lung injury and observe the influence of N-acetylcysteine (NAC). Methods The lung histopathology was observed by light microscope. The level of 8-iso-prostaglandin F2?lpha (8-iso-PGF2?) in blood plasm were measured by ELISA. The difference of 8-iso-PGF2? in blood plasm in air group, different dose NAC groups between hyperoxia-model and the air group was compared. Results In hyperoxia-model group, the inequality of size of lung alveoli, hemorrhage and inflammatory cell infiltration in lung alveoli were observed on the 3rd and 7th day. The alveolar septum was thick in the hyperoxic-damaged lungs on the 14th and the 21st day. In hyperoxia+high-dose NAC group, very small amounts of red blood cells leaked out into alveoli on the 3rd and 7th day and alveolar septum had no thickening obviously on the 14th day and the 21st day. The level of 8-iso-PGF2? in blood plasm in hyperoxia-model group [(28.33?5.57) pg/ml, (51.21?15.01) pg/ml, (84.54?14.85) pg/ml and (43.14?11.37) pg/ml at every time points] was higher than that of the air group and hyperoxia+high-dose NAC group(P

OBJECTIVE:To evaluate the radiosensitization effect of docetaxel versus sodium glyci-didazole.METHODS:A total of 105 patients with intermediate or advanced stage nasopharyngeal carcinoma were randomly assigned to receive docetaxel 40 mg once a week plus radiotherapy or sodium glycididazole 1 000 mg three times a week(Monday,Wednesday and Friday) plus radiotherapy for a total of 7 weeks,or radiotherapy only(control group).RESULTS:There were significant differences between docetaxel group or sodium glycididazole group and control group in sensitization efficiency and radiation dose on tumor regression(P0.05).CON-CLUSION:Lower dose docetaxel is better than sodium glycididazole in radiosensitization efficiency for advanced nasopharyngeal carcinoma,especially in controlling the metastasis,yet it has minimal side effect.

Objective To explore effects of fosinopril and losartan on renal Klotho expression and oxidative stress in spontaneously hypertensive rats (SHR) and the mechanisms underlying the protection against renal damage. Methods Fifteen male SHRs (22 weeks old) were randomly divided into 3 groups (n=5 in each group): a SHR group, a fosinopril group ［10 mg/(kg?d)］, and a losartan group ［50 mg/(kg?d)］. Age-matched Wistar-Kyoto (WKY) rats were chosen for a control group. Eight weeks later, tail arterial pressure, 24 hours urinary protein (Upro)，urinary N-acetyl-β-D-glucosaminidase (NAGase) were measured. Renal pathological changes were examined under light microscopy by HE staining. The renal mRNA and protein expression of Klotho were determined by RT-PCR, immunohistochemical staining or Western blot. The levels of total antioxidant capacity (TAOC), malondialdehyde (MDA), Cu/Zn superoxide dismutase (Cu/Zn-SOD), Mn superoxide dismutase (Mn-SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) were determined.Results The typical pathological characteristics of hypertensive renal damage were observed in the kidney of the SHR group．Compared with the SHR group, the systolic pressure, Upro, and urinary NAGase, the content of MDA and renal pathological damage was reduced while the renal Klotho expression and activities of TAOC, Cu/Zn-SOD, CAT, and GSH-Px were increased (P<0.05 or P<0.01) in the fosinopril or losartan group. There was no significant difference in renal Mn-SOD level among the 4 groups (P>0.05). Conclusion Fosinopril and losartan can exert protection against hypertensive renal damage through upregulating Klotho expression as well as reducing oxidative stress.
