Objective:To compare the therapeutic and adverse effects of concurrent raltitrexed plus oxaliplatin and radiotherapy with those of PF synchronous radiotherapy in the treatment of advanced esophageal cancer. Methods:A total of 84 pathologically con-firmed patients with advanced esophageal carcinoma were randomly distributed to the concurrent raltitrexed plus oxaliplatin and ra-diotherapy group (experimental group, n=40) and to the PF synchronous radiotherapy group (control group, n=44). All patients were treated with 3DCRT at a total dose of 60 Gy/30f. The chemotherapy in the experimental group consists of raltitrexed at 2.5 mg/m2, d1, plus oxaliplatin at 130 mg/m2, d2. The chemotherapy of the control group consists of DDP at 25 mg/m2, Dd1-3, plus 5-FU 500 mg/m2, d1-5. Two cycles of concurrent chemotherapy were administered during radiotherapy on d1 and d29. The comparison results were used to estimate the therapeutic and adverse effects of the two groups. Results:The rerponse rate, complete response, and one-year overall survival rate of the experimental group were higher than those of the control group [(87.50%vs. 79.54%, P=0.3293), (32.50%vs. 18.18%, P=0.13), and (82.50%vs. 79.50%, P=0.701)], but the difference was not statistically significant. The incidence rates of nau-sea and vomiting, appetite degression, leucopenia, radiation-induced esophagitis, and cardiotoxicity were significantly lower (P<0.05) in the experimental group than in the control group. Other adverse effects of the two groups were similar (P>0.05). Conclusion:Simi-lar to PF chemotherapy and radiotherapy, the concurrent raltitrexed plus oxaliplatin and radiotherapy achieved a similar short-term therapeutic effect but lower adverse effects on patients with esophageal cancer.

Objective To study the differences of coagulation indices on the first day of birth in newborns with different gestational ages.Method Premature infants born in our hospital between January 2014 and December 2015 were enrolled in this study as the observational group,and they were divided into early preterm group,moderate preterm group,and late preterm group according to their gestational ages.Healthy full-term infants born during the same period were selected as the control group by 3:1 The clinicaldata and coagulation indices of the infants and their mothers in each group were compared.Result There were 44,50,71,and 52 cases in the early preterm,moderate preterm,late preterm,and control group,respectively.The prothrombin time (PT),activated partial thromboplastin time (APTT),and thrombin time (TT) of the premature infants in the early preterm group,moderate preterm group,and late preterm group were all longer than those of the control group [PT:(16.1 ±4.3) s,(16.8 ±4.9) s,(15.8 ±4.8) s,vs.(13.0±1.3)s;APTT:(88.3±38.1) s,(93.5±37.7) s,(91.0±32.3) s,vs.(66.0±17.8) s;TT:(25.4 ±4.6) s,(25.1 ±5.5) s,(25.0 ±3.3) s,vs.(24.0 ±3.3) s;all P<0.05].The fibrinogen level of the premature newborns in three groups were all lower than that of the full-term infants in the control group [(1.11 ± 0.46) g/L,(1.12 ± 0.44) g/L,(1.12 ± 0.45) g/L vs.(1.28 ± 0.37) g/L,P < 0.05].The differences of all the indices among the three groups of premature infants were all not statistically significant (P > 0.05).The comparison of the coagulation indices of the mothers of the newborns from all four groups showed no significant differences (P > 0.05).Conclusion Compared with full-term infants,preterm infants showed significantly poorer coagulation function on the first day of birth.However,there were no significant differences in coagulation indices among preterm infants of different gestational ages.

BACKGROUND: Studies have shown that bone marrow mesenchymal stem cells have the potential of differentiation into alveolar epithelial cells in vitro, but so far no study has indicated that adipose-derived mesenchymal stem cells (ADSCs) can be differentiated into alveolar epithelial cells through long-term Transwell co-culture. OBJECTIVE: To observe whether rat lung epithelial-T-antigen negative cell lines (RLE-6TN) can induce rat ADSCs to differentiate into type II alveolar epithelial cells by long-term Transwell co-culture. METHODS: Three SPF health female Sprague-Dawley rats were used as donors to separate, extract, culture and identity ADSCs. The experimental group was subjected to the Transwell co-culture of ADSCs and RLE-6TN, while the control group was subjected to the culture of ADSCs alone. The morphological changes of ADSCs were observed by the inverted phase contrast microscope at 21 days after co-culture. Immunofluorescence staining using surfactant protein C (SP-C) was performed on the co-cultured ADSCs. The fluorescence staining was observed using the inverted fluorescence microscope. Integral optical density (IOD) analysis was conducted by Image pro plus 6.0 software. RESULTS AND CONCLUSION: RLE-6TN cells were identified by fluorescence staining with stable expression of SP-C protein (red fluorescence) in the experimental group, and there was no red fluorescence in the control group. After 21-day co-culture, the cell shape in the experimental group was transformed from the long spindle shape into oval or polygon shape gradually, while the cell shape in the control group remained fibroblast-like. These results show that RLE-6TN can induce ADSCs to differentiate into type II alveolar epithelial cells after a long-term (21 days) co-culture.

Objective To determine the expression of Cyclin B1,p34cdc2 and the phosphorylation of survivin(p-survivin)in oral squamous cell carcinoma and oral submucosa fibrosis(OSF),and to discuss their possible role in carcinogenesis of OSF.Methods The expression of Cyclin B1,p34cdc2 and p-survivin were analyzed by Western blotting assay in 10 cases of normal oral mucosa epithelium,40 cases of OSF epithelium and 42 cases of oral squamous cell carcinoma(OSCC)originated from OSF,respectively.Immunoprecipitation was used to confirrn the relationship between the p34cdc2 and survivin.Results The expression of Cyclin B1,p34cdc2,p-p34cdc2 and p-survivin in OSF group were significantly higher than those in normal group(P<0.05).The expression of these molecules showed significant different(P<0.05)between the OSF and OSCC originated from OSF,but there was no significant difference among the early stage,the moderately advanced stage and the advanced stage of OSF.Immunoprecipitation assay confirmed the combination of p34cdc2 and survivin.Conclusions The important molecules in G2/M phase-Cyclin B1,p34cdc2 and p-survivin may play a key role during the mitosis and proliferation of OSF,which will be helpful in early diagnosis and therapy of carcinogenesis of OSF.

OBJECTIVETo evaluate the significance of determining ascitic bacterial 16S rRNA by quantitative PCR combined with microarray (PCR-microarray) in the diagnosis of spontaneous bacterial peritonitis (SBP).
METHODSAscitic bacterial 16SrRNA was determined by real time fluorescent quantitative PCR-microarray in 76 cases of suspected SBP and 6 cases of non-infectious ascites with chronic liver diseases. The results were compared with ascitic bacterial culture simultaneously.
RESULTSOf 76 ascitic samples, 17 were detected bacteria positive by PCR-microarray, including 8 Grams positive(G+) and 9 Grams negative(G-), which was higher than that by bacterial culture which had only 6 ascitic samples detected positive (all G-); the positive rates were 22.4% vs 7.9%, respectively (P < 0.01). The bacterial strains detected by both methods in 6 cases had a consistency with each other. No bacteria were detected in another 6 cases of non-infectious ascites with chronic liver diseases.
CONCLUSIONSDetermination of ascitic bacteria 16S rRNA by PCR-microarray has a higher specificity and sensitivity in the diagnosis of SBP as compared with the bacteria culture. Application of this novel method can not only accelerate SBP diagnosis but also stratify the different pathogens.

OBJECTIVESTo elucidate the treatment of Ureaplasma urealyticum (UU) and Chlamydia trachomatis (CT) infectious chronic prostatitis.
METHODSForty-eight cases of chronic prostatitis patients with UU and CT infections were treated with minocycline, Chinese medicine "Qianlieshulekeli" and alpha 1A adrenoceptorblocker (tamsulosin) for 6 weeks. The change of symptoms, expressed prostatic secretion (EPS) routine, and UU and CT detection results were observed before and after the treatment. The efficacy of treatment were evaluated by CPSI score.
RESULTSRemarkably effective-41 cases (85.4%), effective-5 cases (10.4%), noneffective-2 cases (4.2%). CPSI score reduced from (22 +/- 8) before treatment to (7 +/- 3) after treatment (P < 0.01). UU in 20 of 24 cases (83%) and CT in 25 of 28 cases (89%) turned negative after treatment.
CONCLUSIONSThe therapy combining Chinese medicine with western medicine for the treatment of UU and CT infectious chronic prostatitis is successful.
