OBJECTIVE:To explore the correlation between ornidazole (ONZ) salivary concentration and plasma concentra-tions in healthy subjects,and to provide reference for clinical therapeutic drug monitoring. METHODS:24 healthy volunteers were selected. After oral administration of ONZ capsules 1.00 g,their venous blood and saliva were collected at 0.25,0.5,1.5,5.5, 10.5,24.5 and 43.5 h after medication. HPLC method was used to determine the plasma and salivary concentrations of ONZ. The correlation between the two was analyzed. RESULTS:The peak values of plasma and salivary ONZ concentrations appeared imme-diately at 1.5 h after administration and the peak values were(0.96±0.15)μg/ml and(0.93±0.15)μg/ml;salivary concentration of ONZ was lower than plasma concentration at each time points,but there was no statistical significance (P>0.05);the regres-sion equation of salivary ONZ concentration and plasma concentration was csaliva=1.176 5cplasma-0.199 4(r=0.990 1). The ratio of salivary concentration and plasma concentration of ONZ (S/P) was (0.91 ± 0.06),showing positive correlation (r=0.632-0.970, P<0.05). CONCLUSIONS:The salivary ONZ concentration is significantly correlated with plasma concentration in healthy peo-ple,so saliva can be used for therapeutic drug monitoring.

Such parameters of TiO2 nanoparticle by Sol-gel method are analyzed through X-ray and SEM as the gelation time,crystal structure,particle size and morphology.

It has been shown, however, that in terms of immune function, a transitional stage of dendritic cell maturation exists between immature myeloid dendritic cells (imDCs) and mature dendritic cells (DCs), which were named semimature dendritic cells (smDCs). Therefore, the theory that DCs can be classified as imDCs and mDCs has been challenged because of finding smDCs. SmDCs and imDCs are regarded as tolerogenic dendritc cells while what concrete mechanism taken by smDCs and imDCs in transplantation immunity has yet to know. The authors analyzed the important roles and the advanced molecular mechanism of smDCs and imDCs in transplantation immunity in order to update and widen understand underlying tolerogenic dendritic cells.

Objective To study the influence of UPPP on resonance characteristics of four resonance cavity in patients with OSAHS .Methods Using multi-channel voice analysis system to test the cavity resonance character-istics and energy distribution of 36 OSAHS patients (including pre - and post -operative) and 36 normal males when they speak /a:/.The frequency spectrum was 4 000Hz(FR1 ,FR2 ,FR3 ,FR4 ) .Results FR2 energy values of the head cavity and mouth cavity of OSAHS patients heighten significantly after UPPP (P<0 .05);FR1 energy val-ues of head ,mouth and thoracic cavity were higher than that of in normal males'after UPPP(P<0 .05) .FR2 ,FR3 , FR4 energy values of head cavity ,FR2 ,FR3 energy values of mouth cavity ,FR2 energy values of thoracic cavity were lower than those of in normal males'after UPPP(P<0 .05) .Conclusion UPPP surgery removes the obstruction of the upper airway of OSAHS patients and changes the morphology of the pharynx ,thas changes the resonance charac-teristics of the head cavity and oral .

OBJECTIVE: To compare the postoperative nutritional status and the incidence of postoperative infection between post-laryngectomy patients with early eternal nutrition and those with normal liquid diet. METHOD: The observational group were given eternal nutrition while the control group were given normal liquid diet. Nutrition indicators (total protein, albumin, globulin, prealbumin, hemoglobin, body weight) and immune parameters (lymphocyte count) were measured at preoperative day 3 and postoperative day 3, 7 and 10. The incidence of complications and postoperative hospitalization days were compared and analyzed. RESULT: Compared with the control group, the total protein, albumin and globulin of observational group had no statistic significance at postoperative day 3, the total protein, albumin,globulin of observational group were higher (P<0. 05) at postoperative day 7 and 10: The body weight had no satisic significance at postoperative day 3 and 7, while observation group higher at postoperative day 10, while the hemoglobin of observational group had no statistic significance: The prealbumin and lymphocyte count had no statistic significance. The postoperative hospitalization days of the observational group was lower (P<0. 05) than the control group. CONCLUSION The early eternal nutrition for post-laryngectomy patients are conducive to improve of nutritional status and reduce the rate of post-operative complications.

Objective To understand the expiration date of alcohol-based hand disinfectant after it is opened for use,and provide reference for rational clinical application of alcohol-based hand disinfectant.Methods 20 bottles of the same brand alcohol-based hand disinfectant which opened at the same time by the clinical departments were selected as the study object,hand hygiene compliance in theses departments ranked fourth from the end in the hospital,specimens were taken on the first day after opening,and repeated every 10 days until the disinfectant was used up.Hand specimens were also taken after disinfected by disinfectant.Qualified condition of disinfectant and hand specimens was detected.Results A total of 98 disinfectant specimens were collected,by naked eye observation,20 bottles of alcohol-based hand disinfectant were free of discoloration,precipitation,and suspended matter during the whole study period.The qualified detection rates of alcohol-based hand disinfectant within 60 days after opening were all 100%.44 hand specimens were taken and detected after disinfection,3 of which were unqualified(all were disinfected by alcohol-based hand disinfectant 50 days after opening),then detected again after disinfected by the same batch of disinfectant,all were qualified,which suggested that unqualified detection result of hand specimens was not due to disinfectant.Conclusion Alcohol-based hand disinfectant still has a good bactericidal effect on the sixth day after opening.

Objective To study the changes of neutrophil surface molecule CD64 and inflammatory factor levels in patients with burn infection. Methods 46 cases of patients with burn infection who were treated in the department of burn in our hospital between March 2010 and October 2015 were selected as the observation group. Meanwhile, 46 cases of healthy people who underwent physical examination in our hospital during the same period were included in the control group. The levels of neutrophil surface molecule CD64, C-reactive protein (CRP), white blood cell count (WBC) and inflammatory factor [interleukin IL-6 (IL-6), interleukin (IL-8), tumor necro-sis factor (TNF-α) in the two groups of subjects were determined by flow cytometry and were compared. Results In the observation group, the levels of CD64, CRP, WBC and inflammatory factors were significantly higher than those in the control group (P < 0.05). Conclusion The levels of CD64, CRP, WBC and inflammatory factors in patients with burn infection are significantly higher than those in healthy people , which indicates that neutrophil surface molecule CD64, inflammatory factors and burn infection are closely correlated.
