OBJECTIVE To investigate the factors influencing the effects of disinfection of HBV on dental hand piece. METHODS After polluted with HBV positive serum,the dental hand piece was disinfected with sterilizer at the condition of 134℃ for 5 minutes according different treatment procedures.The samples were then taken and detected HBsAg by the automatic enzyme immune analyzer using the third generation EIA agent.The efficacy of disinfection of HBV was presented by the reaction of HBsAg detection. RESULTS If the dental hand piece was sterilized directly not cleansed using clean water after pollution and dried in room temperature,there were 96.87% of the samples being HBsAg positive,and the polluted but dried hand piece,even cleansed there were 87.5% of positive result, even if prolonged the time of sterilization and the frequencies of vacuumization,the HBsAg positive rate of the sample was still up to 56.25%.But if the hand piece was irrigated and cleansed immediately after pollution and sterilized,all samples were HBsAg negative. CONCLUSIONS Whether or not cleansed immediately is the most important factor influencing the efficacy of hand piece sterilization after pollution.

Objective To observe the complications and mortality of hyponatremia in patients with acute exacerbation of chronic obstructive pulmonary disease.Methods The patients with acute exacerbation of chronic obstructive pulmonary disease were selected and divided into non -hyponatremia group(252 cases)and hyponatremia group(65 cases).The differences in the general status,serum ions,blood gas,APACHE Ⅱ score,complications dur-ing the hospitalization,using of ventilator and mortality between the two groups were compared,and drew the receiver operating characteristic(ROC)curve,to acquire higher serum sodium cut -off values.Results In the hyponatremia group,the body weight was (68.3 ±14.4)kg,BMI was (25.5 ±4.9)kg/m2 ,those in the non -hyponatremia group were (74.9 ±15.9)kg and (28.2 ±5.3)kg/m2 respectively,there were statistically significant differences(t =2.009,8.494,all P <0.05).The incidence rate of pneumonia in the hyponatremia group was 23.1%,which was higher than 13.1% in the non -hyponatremia group(χ2 =4.007,P =0.045).The hospital days of the hyponatremia group was (13.1 ±8.9)d,which was longer than (7.8 ±4.9)d of the non -hyponatremia group(t =15.638,P =0.000).The invasive ventilation days of the hyponatremia group was (1.1 ±0.4)d,which was longer than (0.9 ± 0.1)d of the non -hyponatremia group(t =2.885,P =0.004).The non invasive ventilation days of the hyponatremia group was (3.1 ±0.8)d,which was longer than (0.8 ±0.3)d of the non -hyponatremia group (t =2.984,P =0.003).The hospital mortality rate of the hyponatremia group was 12.3%,which was higher than 3.1% of the non -hyponatremia group(χ2 =7.189,P =0.007).The 90 -day mortality rate of the hyponatremia group was 29.2%, which was higher than 15.1% of the non -hyponatremia group(χ2 =7.017,P =0.008).When the serum sodium cut-off value was 128.8mmol/L by drawing ROC curve,the mortality rate in patients with lower than this value was 26.3%,while the mortality rate in patients with higher than the value was 3.7%.Conclusion Hyponatremia is related with the severity and prognosis of acute exacerbation of chronic obstructive pulmonary disease.It is most important to prevent and correct hyponatremia at early disease stage.
