Objective To explore the utility of videofluoroscopy in observing swallowing dysfunction after severe traumatic brain injury (TBI). Methods Videoflouroscopic studies of swallowing (VFSSs) were performed on 40 patients with severe TBI as well as 40 healthy matched controls.Information about penetration and aspiration was collected,and oral delay time (ODT),oral transit time (OTT),pharyngeal delay time (PDT),pharyngeal transit time (PTT) and the maximum vertical and anterior movement of hyoid bone were measured. Results Seventeen of the healthy controls (42.5％) displayed mild penetration,though none had severe penetration or aspiration.Among the severe TBI patients,5 ( 12.5％ ) displayed mild penetration,12 (30.0％) showed severe penetration and 17 (42.5％) subjects had aspiration.The 3ml liquid swallowing parameters of the severe TBI group were ODT ( 0.86 ± 0.37) s,OTT (0.73 ± 0.28 ) s,PDT ( 0.50 ± 0.35 ) s and PTT(0.61 ± 0.11 ) s.The maximum vertical hyoid bone movement in this group averaged (0.98 ± 0.38) cm,and maximum anterior movement was (0.37 ±0.37) cm.The healthy controls and severe TBI patients showed significant differences in terms of all six measures.Conclusion Dysphagia was found to be frequent among severe TBI patients,commonly occurring in the oral and pharyngeal phases.Videoflouroscopy may be helpful for identifying the main features of dysphagia and formulating better rehabilitation strategies.

Objective: To explore the relationship between strain rate parameter and left ventricular diastolic function (LVDF) in patients with cardiac resynchronization therapy (CRT) by two-dimensional speckle tracking echocardiography (2D-STE).
Methods: A total of 70 heart failure (HF) patients with CRT were studied. The early left ventricular diastolic strain rate was obtained by 2D-STE technology, the differences of left ventricular diastolic functional parameters to various CRT echocardiographic responses were observed. The area of relevant parameters under ROC curve was calculated by early left ventricular diastolic strain rate for predicting CRT echocardiographic response.
Results: There were 41 patients presented as CRT echocardiographic responders at 12 months of follow-up period, 29 patients were non-responders. The most parameters of LVDF were signiifcantly improved than the base line in 41 responders. The maximum area of 2D-STE derived parameters under ROC curve was obtained by LSRE predicted CRT echocardiographic response
Conclusion: LSRE had greater value for predicting CRT echocardiographic response, it might be used as a sensitive index for evaluating LVDF in HF patients.

Objective To study whether the Chlamydia Trachomatis (CT) growth cycle affects the results of culture of CT infection, clinical symptom and the effectiveness of antibiotics .Methods The 302 cases from genecology out-patients were classified into two groups: the symptomatic ones (group A) and the asymptomatic another (group B), and The CT infection was examined by both PCR technique and culture medium, the positive cases were revisited twice later.Results ⑴There was no difference between two diagnostic methods in the group A. While in the group B, the positive rate of with PCR method was 8 91%(18/184), which was higher than that in culture medium 2 48%(5/197),P0 05. Total 96%(48/50) of cases from the double positive group revert to culture negative, only 36%(18/50) of cases were cured, while 60%(30/50) ones just get to the single positive group in PCR method.⑷After ceasing antibiotics for at least one month, those who have not been cured revisit again, 13 33%(4/30) of single positive cases with PCR method was reverted to double positive with PCR,culture medium methods.Conclusion CT infection in female genital system,positive determinable rate of PCR method is higher than that of culture medium method.

Objective To study the immunoregulatory activity of eucommia ulmoides oliv polysaccharides (EOP) on immunodepressive mice. Method The immunodepressive mice model was established with cyclophosphamide (CY) treated. EOP was given with different doses, and mouse weight, thymus index, spleen index, abdominal cavity macrophage engulfing rates, engulfing index were measured.
