Background:Concurrent chemoradiotherapy (CCRT) significantly increases the survival rate of esophageal squamous cell carcinoma (ESCC) patients with malignant fistulae.Recent clinical evidence has shown the benefits of enteral nutrition for malnourished cancer patients.In this study,we aimed to validate that,with the support of enteral nutrition,ESCC patients who develop malignant fistulae might be able to complete CCRT and achieve long-term survival.Methods:We reviewed the medical records of 652 patients with ESCC who received definitive CCRT at Sun Yat-sen University Cancer Center between January 2010 and December 2012.Treatment outcome and toxicity were retrospectively evaluated in 40 ESCC patients with malignant fistulae.All the 40 patients were treated with CCRT and evaluated by clinical nutritionists using nutrition risk screening (NRS) before,during,and after treatment.Twenty-two patients received a nasogastric tube,and 18 underwent percutaneous endoscopic gastrostomy feeding.The median energy intake was 2166 kcal/day.Treatment response was evaluated at 3 months after the completion of CCRT.Results:With a median follow-up of 18 months (range,3-39 months),patients' 1-year overall survival (OS) rate was 62.5％,and the estimated OS time was 25.5 months.Univariate analysis showed that the NRS score (P =0.003),increase in NRS score (P =0.024),fistula closure (P =0.011),and response to treatment (P ＜ 0.001) were significantly associated with OS.Multivariate analysis showed that tumor response (P =0.044) and increase in NRS score (P =0.044) were independent predictors of OS.Grade 3 vomiting was observed in 8 patients (20.0％),grade 3 neutropenia was observed in 11 patients (27.5％),and grade 3 cough was observed in 13 patients (32.5％);2 patients (5.0％) died of massive bleeding during treatment.Conclusions:CCRT combined with enteral nutrition support is effective for ESCC patients with malignant fistulae.Patients have an increased potential to be cured,especially those who experience complete response and have an increase in NRS score.Careful observation and nutrition support are required for patients with advanced T-category ESCC who undergo CCRT.

AlM: To evaluate the effect of rigid gas permeable contact lens ( RGP ) in correcting high myopia and astigmatism.METHODS: Forty-one patients ( 65 eyes ) with myopia (-9. 03 ± 6. 19DS, maximum -23. 00DS) and astigmatism (-1. 41 ± 1. 32DC, maximum -5. 50DC) were fitted with RGP after strict routine ophthalmological examination, objective refraction and subjective refraction. All these patients were followed after 1wk, 1, 3mo and half one year.RESULTS:Sixty-five eyes were fitted with RGP (-9. 92± 5. 96DS). RGP base curve ( BC) was majorly located within the range 7. 20 ~8. 25mm. 46. 2% eyes with RGP achieved 1. 0 ( BCVA ) and 80. 1% achieved above 0. 6 ( BCVA) . However, with spectacles, the percent was 28%(1. 0) and 60% (>0. 6), respectively. BCVA of RGP was 0. 81 ± 0. 22, but BCVA with spectacles was 0. 66 ± 0. 28, there was statistical significance (P<0. 01). There were 40 eyes (62%) fitted with RGP whose vision were enhanced more than 1 line, 24 eyes ( 37%) whose vision were not changed and 1 eye (2%) whose vision were dropped 1 line.CONCLUSlON:RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.

Objective:To describe the expression profiling of microRNAs of patients with non-small cell lung cancer. Methods:We reduced the scope of downregulated microRNAs in patients with non-small lung cancer by high throughput microarray based on quantitative real-time PCR (qRT-PCR). In this process, the downregulated microRNAs of non-small cell lung cancer tissues can be de-tected and compared with adjacent healthy lung tissues with relatively small samples. Different microRNA expression levels in non-small cell lung cancer and adjacent healthy lung tissues were verified in a large sample by RT-PCR. Results:A total of 20 types of microRNAs were significantly downregulated in non-small cell lung cancer tissues compared with adjacent healthy lung tissues. These microRNAs were listed as follows: hsa-miR-1; hsa-miR-22; hsa-miR-27a; hsa-miR-27b; hsa-miR-125a-5p; hsa-miR-125b;hsa-miR-142-5p;hsa-miR-143;hsa-miR-148a;hsa-miR-148b;hsa-miR-370;hsa-miR-373;hsa-miR-381;hsa-miR-489;hsa-miR-519a;hsa-miR-376c;hsa-miR-206;hsa-miR-380-5p;hsa-miR-223-5p;and hsa-miR-520c-3p. Among these microRNAs, 13 types were down-regulated in non-small cell lung cancer tissues as verified by RTPCR. These 13 types of microRNAs were listed as follows:hsa-miR-125a-5p; hsa-miR-143; hsa-miR-519a; hsa-miR-223-5p; hsa-miR-1; hsa-miR-520c-3p; hsa-miR-489; hsa-miR-27a;hsa-miR-373; hsa-miR-125b; hsa-miR-27b; hsa-miR-142-5p; and hsa-miR-206. Conclusion: In non-small lung cancer tissue, several kinds of microRNAs were significantly downregulated. Changes in microRNA expressions were significantly associated with tumori-genesis, progression, or other cancer cell functions in non-small cell lung cancer.

The applicator therapy is a unique method to treat infant diarrhea in traditional Chinese medicines and widely applied in clinical practice. Currently, many researchers have proved the rationality of the therapy based on the traditional Chinese medicine mechanism and on the data from clinical practice, but its action mechanism is uncertain at present. In this study, with the assistance of pediatric practitioners, the automated ribosomal intergenic-spacer analysis (ARISA) was adopted to study the effect of the adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants, in which Dingguier umbilical paste served as the adjuvant therapy in oral traditional Chinese medicines and fecal samples of infants with different diarrhea symptoms were collected and used as the study materials. The results showed that the adjuvant therapy had a significant effect on the shift of intestinal flora, which was associated with the decrease in the similarity difference to the normal control group and the increase in the number of operational taxonomic units (OTUs) shared with the normal control group. Additionally, adjuvant therapy with Dingguier umbilical paste also showed long action duration and increased OTUs number. These results indicated that Dingguier umbilical paste has the effect in restoring the micro-ecosystem of unbalanced intestinal bacteria. Intestinal flora may be one of major targets for the applicator therapy for the infant diarrhea, but not for the single oral traditional Chinese medicine for infant diarrhea.
