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 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 compare the treatment effects of secreory otitis media with artificial eustachian tube insertion and tympanotomy tube insertion.To provide useful information for the treatment of secretory otitis media.METHODS Seventy-one patients(86 ears) with secretory otitis media were randomly divided into tow groups:experimental group(36 cases,44 ears) and control group(35 cases 42 ears).The experimental group was treated by artificial eustachian tube insertion under nasal endoscope.Drugs were injected through the tube into the tympanic cavity everyday after flushing it. The control group were treated by traditional method—the tympanic ventilation tube.All patients were followed up for 6 months.RESULTS The experimental group: 21 ears(47.73%) were cured,19 ears(43.18%) were straightened up,and no effects observed in 4 ears (9.09%).The control group:12 ears(28.57%) cured,17 ears(40.48%) wered straightened up and no effects obsered in 13 ears(30.95%).The efficiency rate of the experimental group(90.91%) was much higher than the control group(69.05%,P

Abstract: Objective　To screening new compounds that can inhibit the growth and biofilm formation of Staphylococcus aureus. Methods　Compounds that can inhibit the growth of Staphylococcus aureus were screened from the FDA approved drug library by 96 well plates. The absorbance value of 600 nm wavelength (OD600) was measured by Microplate Reader to detect the growth of Staphylococcus aureus planktonic cells in the culture supernatant. The minimum inhibitory concentration (MIC) of ozanimod against Staphylococcus aureus clinical isolates were detected by micro broth dilution method. The inhibitory effect of sub-inhibitory concentrations of ozanimod on the biofilm formation of Staphylococcus aureus was detected by crystal violet staining. Results　This study found that ozanimod could significantly inhibit the growth of Staphylococcus aureus SA113 (screening reference strain), and the MIC was 25.00 μmol/L. The MIC of ozanimod against 119 clinical isolates of Staphylococcus aureus [65 isolates of methicillin sensitive (MSSA) and 54 isolates of methicillin resistant (MRSA)] was 12.50 or 25.00 μmol/L. The MIC50 and MIC90 of ozanimod against the 119 Staphylococcus aureus isolates all were 25.00 μmol/L. This study found that 6.25, 12.50, 25.00 μmol/L of ozanimod could significantly inhibit the biofilm formation of 2 MSSA and 2 MRSA. The sub-MIC concentration of ozanimod (12.50 μmol/L) could significantly inhibit the biofilm formation of 14 MSSA and 11 MRSA, but had no inhibitory effect on the growth of planktonic cells of these Staphylococcus aureus isolates. Conclusion　Ozanimod can inhibit the growth of Staphylococcus aureus, including MRSA, and has good antibacterial activity. The sub-MIC concentration of ozanimod could significantly inhibit the biofilm formation of Staphylococcus aureus.

Objective To investigate the diagnosis of a case with 7p15.3p22.1 microdeletion by applying array-based comparative genomic hybridization (array-CGH) and to analyze the relationship between the clinical manifestations and 7p15.3p22.1 microdeletion. Method Array-CGH technique was used to detect genomic copy number variations (CNVs) in an infant with normal karyotype after conventional chromosomal karyotyping. Results Array-CGH detected 7p15.3p22.1 deletion (chr7: 6777262-23981753), which was confirmed as pathogenic CNV after comparative analysis with database. Conclusion Array-CGH could serve as a useful complement for G-banding to be used in the clinical cytogenetic diagnosis.

As a clean, efficient, and renewable energy, hydrogen is regarded as a promising alternative. Because of using biomass as substrate, microbial fermentative hydrogen production can meet the need of sustainable development. The factors affecting the process of microbial fermentative hydrogen production, are analyzed in this paper on the basis of microorganisms, substrates, products and operative parameters. The parameters related to hydrogen production from organic wastes, are also mentioned.
