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.

A bacterial strain which could grow well on the substrate of PAEs as the sole source of carbon and energy was isolated from contaminated sludge in the river of WeiFang in ShangDong province and it was designated as JDC-3. Based on the morphology,biophysical and biochemical properties as well as molecular characteristics,this isolate was preliminarily identified as Delftia sp.. A fragment of phthalate dioxygenase gene was successfully amplified from the genus of Delftia for the first time using a set of degenerate primers. Meanwhile,the degradation capability of JDC-3 was determined by HPLC using DMP as test substrate. The results showed that the optimal pH and temperature were at 7.0～8.0 and 30?C～35?C respectively. The degradation kinetics of JDC-3 was studied in different initial DMP concentration under optimal conditions. The results indicated that the degradation dynamic equation was ln C =-0.06837 t + A when DMP concentration was lower than 300 mg/L,with half life of 12.48 h. The degradation rate decreased and half life of JDC-3 prolonged as the initial concentration kept on increasing.

Objective To observe the effects of comprehensive measures of changing grain,selenium supplementation,off-site education and resettlement on prevention of children's Kashin-Beck disease in Aba state.Methods Fifty eight villages in Aba Kashin-Beck disease areas were chosen as intervention points in Aba state Sichuan province from 2007 to 2011.Based on the implementation of prevention and control measures,the villages were divided into off-site education + changing grain + selenium supplementation group and resettlement + off-site education + changing grain + selenium supplementation group,Geletuo town of Seda county,Ganzi state was selected as a control point,and right-hand anteroposterior X-ray examination(including the wrist) was carried out on children aged 6-13 from 2007 to 2011 annually.Clinical and X-ray diagnosis of Kashin-Beck disease was made in accordance with the Diagnostic Criteria of Kaschin-Beck Disease(GB 16003-1995).The effects of prevention and control measures were evaluated by comparing the child X-ray detection rate before and after the implementation of the measures.Results The average X-ray positive detectable rate of children in the intervention points was 2.07％(66/3181),2.72％ (69/2540),1.16％ (35/3017),0.56％ (19/3397) and 0.56％ (24/4273),respectively from 2007 to 2011,with a downward trend (x2trend =66.74,P ＜ 0.01).There was a downward trend in the average X-ray positive detectable rate of children in off-site education + changing grain + selenium supplementation group [1.60％(29/1809),2.63％ (39/1484),1.29％ (25/1941),0.64％ (15/2332),0.42％ (10/2379)] and resettlement + off-site education + changing grain + selenium supplementation group [2.70％ (37/1372),2.84％ (30/1056),0.93％(10/1076),0.38％ (4/1065),0.74％(14/1894)] (x2trend=30.97,35.19,all P ＜ 0.01).The average X-ray positive detectable rate of children in the intervention group was 0 from 2007 to 2010,and was 1.61％ (1/62) in 2011.The difference of X-ray positive detectable rate was not statistically significant in the control group in the 5 years from 2007 to 2011.The difference of children's X-ray positive detectable rate was not statistically significant between control group and intervention group.Conclusions The effect of taking changing grain,selenium supplementation,off-site education and resettlement comprehensive measures to prevent children's Kashin-Beck disease is not significant in those places where the state of Kaschin-Beck disease is not active.
