OBJECTIVE To choose the marks of screening HBV infective source during surgical operation.METHODS On the basis of the HBV infective threshold value,HBV infective source and HBV susceptibility among the surgeons,to choose the marks of screening HBV infective source during surgical operation.RESULTS Before the immunization of surgeons against HBV,the ratio of HBV infective source between HBsAg positive and HBeAg positive carriers was 19.2% and 83.9%,respectively.That of HBsAg negative and HBeAg negative carriers was 0 and 3.2%.The sensitivity of screening HBV infective source with HBsAg acting as mark was much higher than HBeAg.The specificity was lower than HBeAg.After the immunization of surgeons against HBV,the ratio of HBV infective source between HBsAg positive and HBeAg positive carriers was 0.6% and 3.2%,respectively.None of the negative one was HBV infective source during surgical operation.The sensitivity of screening HBV infective source with HBeAg acting as mark was the same as HBsAg.But the specificity was remarkably higher than HBsAg.CONCLUSIONS Before the immunization of surgeons against HBV,HBsAg acting as the screening mark of HBV infective source during surgical operation is more suitable.After that HBeAg is more suitable.

OBJECTIVE To investigate whether the HBV variant of HBeAg negative influences the practicality of hepatitis Be antigen(HBeAg) serving as a supervising and controlling index of HBV spread during operation.METHODS On the basis of that ascertain the relationship between HBV variant of HBeAg negative and source of HBV infection during operation,to investigate whether the HBV variant influenced the practicality of HBeAg serving as a supervising and controlling index of HBV spread during operation.RESULTS The HBV infectivity from low to high was HBeAg negative operated patients

OBJECTIVE To explore the prevention measures against HBV infection among surgeons.METHODS On the basis of the comparison of the current prevention measures HBV infection during operation in the Eastern and Western countries,new prevention measures that HBeAg serves as a supervising and controlling index of HBV were studied.RESULTS The concentration HBV of HBsAg negative,HBeAg negative and HBeAg positive patients were(100-104),(100-106) and(102-109) ID/ml,respectively.HBV infective threshold value of single layer gloves was 105ID/ml,and that of double layer gloves was 106ID/ml.The viral concentration of all the HBsAg negative patients did not reach the infective threshold value of single layer gloves.83.88% HBeAg positive patients reached the threshold value,from them 80.65% was protected by HBV vaccine and 3.23% remainders exceeded the protection.CONCLUSIONS HBeAg serving as a supervising and controlling index of HBV infection can be an effective indicator which can reduce the risk of infection.It is more suitable for the current condition of our country.

Objective To explore the application effect of the multidisciplinary collaborations in control of peritoneal dialysis patients with hypertension. Methods A total of 220 cases of peritoneal dialysis patients divided into experimental group and control group (each group had 110 cases) according to the random number table. In which, the control group received routine capacity control and health education with a total of 105 patients finished the study. The experimental group received of multidisciplinary collaborations on the basis of routine capacity control and health education with a total of 107 patients finished the study. Observe changes with knowledge of drugs, medication compliance, self-management behavior and blood pressure of patients before and after the intervention respectively. Results In experimental group,the scores of drug knowledge, medication compliance and self-management behaviors were (0.93 ± 0.49), 0.00 (0.00, 0.25), (2.69 ± 0.25) points before the intervention, 6 months after the intervention were (1.17 ± 0.54), 0.25 (0.00, 0.50), (2.86 ± 0.15) points, the difference between the groups was statistically significant (t=38.60, Z=4.34, t= 2.45, P < 0.01 or 0.05). In control group,the scores of drug knowledge, medication compliance and self-management behaviors were (0.87 ± 0.45), 0.00 (0.00, 0.25), (2.64 ± 0.27) points before the intervention, 6 months after the intervention were (0.89 ± 0.43), 0.00 (0.00, 0.38), (2.73 ± 0.27) points, there was no significant difference between drug knowledge and medication compliance (t=0.44, Z=1.83, P > 0.05), there were statistically significant differences in self-management behavior (t=6.23, P<0.01);there was no difference between the statistical significance between the 2 groups before intervention (t=1.02, Z=1.46, t=1.32, P > 0.05); there was significant difference between the 2 groups after intervention (t=4.11, Z=4.03, t=4.34, P<0.01). Patients in the experimental group with the systolic and diastolic blood pressure were (147.11 ± 14.31), (90.16 ± 13.02) mmHg (1 mmHg=0.133 kPa) respectively, before the intervention; 6 months after the intervention were (139.39 ± 17.05), (83.76 ± 12.52) mmHg respectively, the difference was statistically significant (t=3.59, 2.92, P<0.01). The control group before intervention were (149.56 ± 18.11), (93.56 ± 15.09) mmHg respectively, 6 months after the intervention were (145.14±20.50), (88.14±10.88) mmHg respectively, the difference was statistically significant (t=2.02, 2.72, P<0.05 or 0.01);there was no significant difference between the two groups before intervention (t=1.09, 1.82, P>0.05);6 months after the intervention there was significant difference between the 2 groups (t=2.22, 2.72, P < 0.05 or 0.01). Conclusions Multidisciplinary collaborations have a significant role in patients with peritoneal dialysis, especially in blood pressure control, medication compliance and self-management behavior.
