OBJECTIVE To study the clinical effect of Salpingocatheterism combined with Chinese medicine liquid irrigation under endoscope for chronic secretory otitis media(CSOM).METHODS From September 2012 to March 2014,80 patients with CSOM(120 ears) in the clinic were randomly divided into two groups.The experimental group:40 cases(61ears) were treated with Salpingocatheterism combined with Chinese medicine liquid irrigation and the liquid named Qingqiao tang(empirical recipe)was injected for 4 to 7days with 2ml each time.The control group:40 cases(59ears)were treated by myingotomy with grommet insertion.The ventilation tube was generally pulled out after 6 to 8 weeks or dropped out by itself .All patients were followed up for 6 months and the effects were to be evaluated.RESULTS In the experimental group,among 61ears,50 ears were cured,6 showed effectual results,2 were positive to the treatment and 3 showed ineffective results.The cure rate was 81. 97% and the total effective rate was 95.08% .In the control group,among 59 ears,38 ears were recovered,6 showed effectual results,5 were positive to the treatment,10 showed ineffective results.The cure rate was 64.61% and the total effective rate was 83.05% .The therapeutic effect of experimental group was better than that of the control group.The complication rate of the experimental group was 9.84%,while the control group was 28.81%.The complication rate of the experimental group was significantly lower than that of the control group.The recurrence rate of the experimental group was 6 .5 6% while the control group was 20.34%,the recurrence rate in the control group was significantly higher than that of the experimental group.The differences both had statistical significance(P<0.05).CONCLUSION The treatment of CSOM with salingocatheterism com-bined with Qingqiao tang irrigation under endoscope is effective and causes little inj ury.With a low recurring rate and less ad-verse reaction,this treating method is worth of being applied widely.

OBJECTIVETo evaluate the efficacy of hepatitis B viruse (HBV) vaccination and its influencing factors among children in rural area of Jiangsu province.

METHODSTwenty-five hundred and twenty-two children born after 1998 in rural area were selected as the study population using multistage cluster sampling method. HBsAg and anti-HBs were detected by enzyme linked immunoassay (ELISA) and radio-immunoassay (RIA), respectively. Anti-HBs negative children were boosted using different hepatitis B vaccines and the efficacy was compared. Factors causing HBV infection in HBsAg positive children were also investigated.

RESULTSHBsAg positive rates in 1-7 year olds were 0.28%-1.28%, and the anti-HBs positive rates decreased from 76.7% to 45.5%. The HBsAg positive rate in children not timely vaccinated was significantly higher than those with HBV vaccine injection within 24 hours after birth (1.4% vs. 0.5%, P = 0.031). More than 90% of the anti-HBs negative children had protective level of anti-HBs after boosted with HBV vaccine.

CONCLUSIONHBsAg positive rate in children born after 1998 in rural area of Jiangsu province decreased significantly, with an average of 0.8%. The reason for HBsAg carriage in children might be attributed to mother-to-infant transmission or not timely HBV vaccination.

OBJECTIVETo investigate the role of monocarboxylate transporter 1 (MCT1) in enhancing the sensitivity of breast cancer cells to 3-bromopyruvate (3-BrPA).

METHODSThe inhibitory effect of 3-BrPA on the proliferation of breast cancer cells was assessed with MTT assay, and brominated propidium bromide single staining flow cytometry was used for detecting the cell apoptosis. An ELISA kit was used to detect the intracellular levels of hexokinase II, lactate dehydrogenase, lactate, and adenosine triphosphate, and Western blotting was performed to detect the expression of MCT1. MDA-MB-231 cells were transiently transfected with MCT1 cDNA for over-expressing MCT1, and the effect of 3-BrPA on the cell proliferation and adenosine triphosphate level was deteced.

RESULTS3-BrPA did not produce significant effects on the proliferation and apoptosis of MDA-MB-231 cells, and the cells treated with 200 µmol/L 3-BrPA for 24 h showed an inhibition rate and an apoptosis rate of only 8.72% and 7.8%, respectively. The same treatment, however, produced an inhibition rate and an apoptosis rate of 84.6% and 82.3% in MCF-7 cells, respectively. In MDA-MB-231 cells with MCT1 overexpression, 200 µmol/L 3-BrPA resulted in an inhibition rate of 72.44%, significantly higher than that in the control cells (P<0.05); treatment of the cells with 25, 50, 100, and 200 µmol/L 3-BrPA for 6 h resulted in intracellular adenosine triphosphate levels of 96.98%, 88.44%, 43.3% and 27.56% relative to the control level respectively.

CONCLUSIONMCT1 can enhance the sensitivity of breast cancer cells to 3-BrPA possibly by transporting 3-BrPA into cells to inhibit cell glycolysis.

OBJECTIVESTo detect the loss of heterozygosity (LOH) of circulating DNA in the plasma of patients with hepatocellular carcinoma (HCC), and to assess its potential as a clinical predictive marker.

METHODSThree high-polymorphic microsatellite markers D8S277, D8S298 and D8S1771 located at chromosome 8p were selected to detect LOH in plasma DNA of 62 HCC patients. The associations between LOH and its clinicopathological features, including HBsAg, liver cirrhosis, serum AFP level, tumor size, tumor cell differentiation, and intrahepatic metastasis were also examined.

RESULTSIn plasma DNA of the 62 HCC patients, LOH was found at one or several loci in 36 (58.1%), and heterozygosity at D8S277, D8S298, and D8S1771 loci was 74.2% (46/62), 75.8% (47/62), and 69.4% (43/62), respectively. LOH frequency at D8S277, D8S298 and D8S1771 was 32.6% (15/46), 44.7% (21/47), and 46.5% (20/43), respectively. LOH in plasma DNA was more frequently detected in the patients with intrahepatic cancer metastasis than those without metastasis (62.5 percent vs. 26.1 percent, P < 0.05); however, no statistically significant correlations were observed between LOH at these loci and other clinicopathological features analyzed in this study.

CONCLUSIONSLOH at D8S298 in plasma DNA may be a potential predictive marker of intrahepatic metastatic recurrence after surgical resection of the HCC.
