Background and purpose:Currently, subjective questionaire is the most frequently used methods to evaluate swallowing dysfunctions after radiotherapy in nasopharyngeal carcinoma patients, while lacking of effective objective examinations. This study aimed to explore effective methods to evaluate swallowing dysfunctions after radiotherapy in nasopharyngeal carcinoma patients, and gain knowledge of the incidence and severity of swallowing dysfunctions. Methods: From Oct. 2013 to Dec. 2013, 128 consecutive outpatients with previously treated nasopharyngeal carcinoma received esophageal barium lfuoroscopy examination at there regularly follow-ups to evaluate swallowing function. Among these patients, 89 were primary treated with intensity modulated radiation therapy (IMRT) and 39 with conventional radiotherapy (CRT). In this study, each patient received esophageal barium lfuoroscopy examination for 3 times with thin, thick and pasty barium and were dynamically observed using X-ray fluoroscopy from front and lateral direction. Swallowing dysfunctions were defined as follows:①The bolus could not be swallowed and blocked in the mouth;②The dilute barium diverted to the glottis or trachea;③Residual barium delayed in the pyriform sinus and vallecula;④The movement of the hyoid bone or epiglottis were restricted;⑤Bolus prolong through the pharynx;⑥Barium slowed down when went though the esophageal entrance. Results:Of the 128 patients, incidence of dysphagia was 60.2%for the entire cohort, 52.8%for IMRT group and 76.9%for CRT group. Incidence of dysphagia for IMRT group was signiifcantly lower than CRT group (P=0.018). Dysphagia incidence within 1 year, 1 to 2 years and more than 2 years after RT were 63.1%, 33.3%and 69.0%, respectively (P=0.019). Conclusion:There was a high incidence of swallowing dysfunction for the nasopharyngeal carcinoma patients treated with radiotherapy and dysphagia incidence decreased when treated with IMRT. Esophageal barium lfuoroscopy examination is objective method to evaluate the incidence and severity of the swallowing dysfunction.

Objective To reduce the incidence of the hypocapnia,the cutoff value of the end-tidal carbon dioxide partial pressure[Pet(CO2)] for predicting the hypocapnia so as to understand the suitable adjustment target and target range of the Pet(CO2) in preterm infants under mechanical ventilation.Methods From Jan.2012 to Oct.2013,96 cases of the preterm infants with respiratory distress syndrome(RDS) who needed mechanical support were selected from the Huaian Maternity and Child Health Care Hospital.Pet(CO2) value of each time point(1 h,24 h,48 h and 72 h after mechanical ventilation) were recorded,while radial artery blood was collected for blood gas analysis.The level of pa (CO2) ＜ 35 mmHg(1 mmHg =0.133 kPa) diagnosed hypocapnia;while the level of Pa (CO2) ＞ 60 mmHg was for diagnosing hypercapnia.The diagnostic cutoff and the suitable adjustment target and adjustment target range of the Pet(CO2) were confirmed by receiver operating characteristic (ROC) curve.Results The data from 381 arterial blood gas analysis results were gained,of which 151 times belonged to hypocapnia,and the rate was 39.6％,the other 230 cases were normal,and no case was of hypercapnia.The area under the ROC curve was 0.895,and the area of the standard error was 0.016.There was a statistical significance in Pet(CO2) value for the diagnosis of hypocapnia(P =0.000).The lower the value of Pet (CO2),the greater the likelihood of hypocapnia,and 95 ％ confidence interval area was 0.864-0.926.The Pet (CO2) optimal diagnostic cutoff value determined in accordance with Youden index was 30.5 mmHg.When Pet (CO2) among 41.5 mmHg,sensitivity was 100％.Conclusions Diagnostic cutoff value for forecasting hypocapnia is 30.5 mmHg.The suitable adjustment target of mechanical ventilation parameter adjustment is 41.5 mmHg for the Pet(CO2).The target range of mechanical ventilation parameter adjustment is 30.6-41.5 mmHg for the Pet(CO2).

The Streptococcus suis serotype 2 (S. suis 2) isolates 05ZYH33 and 98HAH33 have caused severe human infections in China. Using a strand-specific RNA-seq analysis, we compared the in vitro transcriptomes of these two Chinese isolates with that of a reference strain (P1/7). In the 89K genomic island that is specific to these Chinese isolates, a toxin–antitoxin system showed relatively high levels of transcription among the S. suis. The known virulence factors with high transcriptional activity in these two highly-pathogenic strains are mainly involved in adhesion, biofilm formation, hemolysis and the synthesis and transport of the outer membrane protein. Furthermore, our analysis of novel transcripts identified over 50 protein-coding genes with one of them encoding a toxin protein. We also predicted over 30 small RNAs (sRNAs) in each strain, and most of them are involved in riboswitches. We found that six sRNA candidates that are related to bacterial virulence, including cspA and rli38, are specific to Chinese isolates. These results provide insight into the factors responsible for the difference in virulence among the different S. suis 2 isolates.
