Objective To compare the efficacy of low temperature controlled plasma technology by nasal endoscopy and cystectomy via labiogingival groove approach in treatment of nasal vestibular cyst. Methods 38 patients with nasal vestibular cyst from Jan 2013 to Nov 2016 were selected and randomly divided into control group (n = 20) and observation group (n = 18). The control group received cystectomy via labiogingival groove approach and the observation group received low temperature controlled plasma technology by nasal endoscopy. The time of surgery, bleeding volume in surgery, hospitalization, postoperative complications and relapse were collected and compared between the two groups. Results We found that the observation group have less surgery time than that in control group [(65.45 ± 27.51) vs (34.72 ± 17.61) min, P = 0.000], less bleeding volume in surgery [(22.35 ± 18.41) vs (3.17 ± 1.69) ml, P = 0.000), less postoperative complications [(6.35 ± 0.75) vs (3.61 ± 1.19) d, P = 0.000] and less postoperative complications (16 vs 1, P = 0.000), but relapse of the two groups have no statistical difference (1 vs 0, P = 0.783). Conclusions Low temperature controlled plasma technology by nasal endoscopy in treatment of nasal vestibular cyst have many advantages than cystectomy via labiogingival groove approach such as shorter time of surgery, less bleeding volume in surgery, shorter hospitalization and less postoperative complications. Therefore it's worth of applying clinically.

ObjectiveTo investigate the radiosensitizing effect of 3-(5'-hydroxy-2'-furyl)-1-benzyl indazole ( YC-1 ) on hypoxic human adenocarcinoma cell line A549.MethodsMTT assay was used to test the inhibitory effect of YC-1 on proliferation of A549 cells.Clonogenic assay was performed to determine the radiosensitizing effect of YC-1 on hopxic A549 cells.Single-hit multi-target model was used to plot survival curve and calculate sensitization enhancement ratio (SER).The cell cycle and apoptosis were measured by flow cytometry.ResultsThe proliferation of A549 cells was inhibited by YC-1 in a time-dose-dependent manner.In normoxic and hypoxic cells,the IC20 was 16.7 μmol/L and 39.2 μmol/L at 24 h,respectively.In the group of hypoxia plus YC-1,SERD0 and SERDq were 1.11 and 1.26,respectively.In hypoxia,YC-1combined with 2 Gy irradiation could induce cell apoptosis and prolong G2 + M phase arrest ( ( 30.17 ±1.21 )％ ∶ ( 15.44 ±0.96) ％,P =0.000; (21.56 ±0.47 )％ ∶ (6.16 ±0.16)％,P =0.000).Concinsions YC-1 could enhance the radiosensitivity of hypoxic A549 cells.

A rare strain of actinomycetes, with broad-spectrum antimicrobial activity, was isolated from the soil samples from the farmland in the area of Yaohu lake in Nanchang. The information about the taxonomic identification, such as the morphology, physiological properties, cell components and 16S rRNA gene se-quences, suggested that the rare strain of actinomycetes was identified as Micromonospora carbonacea.

Based on the strain of Micromonospora carbonacea JXNU-1 with board-spectrum antimicrobial activity, the technology for the isolation and purification of antibiotic from the fermentation broth of the Micromonospora carbonacea, and its physical-chemical properties were studied. The results showed that, the antibiotic was stable under the condition of high temperature and alkali, but not in acid solution. After the pretreatment of centrifugation and filtration to remove the cells and lipids, the antibiotic was absorbed to negative exchange resin, and the impurity was excluded when 2 mol/L NaCl was used as primary eluent. The antibiotic could be eluted with 20% alcohol as eluent, and the eluting speed of the antibiotic was greatly accelerated as 2 mol/L NaCl was added into 20% alcohol as final eluent. Aqueous solution of the antibiotic was yielded from the alcohol-salt eluant by decompression concentration to wipe off alcohol and by dialysis to exclude salt. One active component was detected in antibiotic solution by paper chromatography, and theHPLC purity was over 99%. As the antibiotic shows positive color-forming reaction to Molish reagents, Benedict’s reagents and Diohenvlamine reagents, combined with the characteristics of absorption spectra, it is deduced that the antibiotic belongs to nucleoside antibiotics.

Objective This is the first study to explore clinical application value of serum Dickkopf-1 (DKK-1) detection in diagnosis of heptocellular carcinoma (HCC) by magnetic solid phase chemiluminescent immunoassay.Methods The level of serum DKK-1 and AFP in 205 cases of HCC,40 cases of liver cirrhosis,and 200 cases of healthy control were quantitatively detected by Magnetic solid phase chemiluminescent immunoassay.The area under ROC curve,sensitivity and specificity of DKK-1 and AFP for diagnosing HCC were calculated.Results The serum level of DKK-1 in HCC group was significantly higher than those of the liver cirrhosis group and healthy control group (P<0.01).DKK-1 maintained diagnostic sensitivity for patients with HCC who were alpha-fetoprotein (AFP) negative (66.3%).ROC curves showed optimum diagnostic cut-off value was 2.4 ng/mL,area under curve (AUC) was 0.822 (95% CI:0.783-0.856),sensitivity 65.9%,and specificity 87.5%).Moreover,measurement of DKK1 and AFP together improved diagnostic accuracy for HCC versus all controls compared with either test alone [AUC 0.915,95%CI:0.886-0.940),sensitivity 81.5 %(P<0.05)].Conclusion Serum DKK-1 detection has an important clinical value for diagnosis of HCC,especially for HCC with AFP negative.The combined detection of serum DKK-1 and AFP can greatly increase sensitivity and accuracy for diagnosing HCC.

Sanjie Zhentong capsules were scanned by using a near infrared spectra probe with different drug mass fraction and the spectral information of capsule shells and contents in it were obtained. Then partial least squares (PLS) models were developed for the prediction of mass fraction of Fritillariae Thunbergii Bulbus and Resine draconis in Sanjie Zhentong capsules.

Objective To establish and verify the prediction model for ischemic cardiovascular disease(ICVD)among the elderly population who were under the current health care programs. Methods Statistical analysis on data from physical examination, hospitalization of the past years, from questionnaire and telephone interview was carried out in May, 2003. Data was from was randomly selected to generate both module group and verification group. Baseline data was induced to make the verification group into regression model of module group and to generate the predictive value. Distinguished ability with area under ROC curve and the predictive veracity were verified through comparing the predictive incidence rate and actual incidence rate of every deciles group by Hosmer- Lemeshow test. Predictive veracity of the prediction model at population level was verified through comparing the predictive 6-year incidence rates of ICVD with actual 6-year accumulative incidence rates of ICVD with error rate calculated. Results The samples included 2271 males over the age of 65 with 1817 people for modeling population and 454 for verified population.All of the samples were stratified into two layers to establish hierarchical Cox proportional hazard regression model, including one advanced age group(greater than or equal to 75 years old), and another elderly group(less than 75 years old). Data from the statically analysis showed that the risk factors in aged group were age, systolic blood pressure, serum creatinine level, fasting blood glucose level, while protective factor was high density lipoprotein; in advanced age group, the risk factors were body weight index, systolic blood pressure, serum total cholesterol level, serum creatinine level, fasting blood glucose level, while protective factor was HDL-C. The area under the ROC curve (AUC)and 95%CI were 0.723 and 0.687-0.759 respectively. Discriminating power was good. All individual predictive ICVD cumulative incidence and actual incidence were analyzed using Hosmer-Lemshow test, x 2=1.43, P=0.786, showing that the predictive veracity was good.Conclusion The stratified Cox Hazards Regression model was used to establish prediction model of the aged male population under a certain health care program. The common prediction factor of the two age groups were: systolic blood pressure, serum creatinine level, asting blood glucose level and HDL-C. Thc area under the ROWC curve of the verification group was 0.723, showing that the distinguished ability was good and the predict ability at the individual level and at the group level were also satisfactory. It was feasible to using Cox Proportional Hazards Regression Model for predicting the population groups.
