RESUMEN

Objective To investigate the cognition influencing factors of regular laboratory monitoring of HBeAg negative in chronic HBV infection,and analyze the related factors of HBeAg conversion. Methods From January 2015 to March 2017,a total of 302 chronic HBV infected patients in Jinin Infectious Disease Hospital were investigated with a questionnaire about disease related cognition. Single factor and multiple factors Logistic regression analysis was used to analyze the influencing factors of regular monitoring behavior and HBeAg conversion. At the same time,163 cases of HBeAg negative HBV infection were divided into the two groups: regular and irregular monitoring, and disease related laboratory tests and the outcomes were analyzed. Results Psychological pressure(OR = 4. 339, 95% CI:1. 322 - 14. 243),antiviral treatment( OR = 5. 149,95% CI:1. 628 - 16. 283),knowledge of hepatitis B (OR = 3. 306,95% CI:1. 108 - 9. 867) and the stability of disease(OR = 3. 229,95% CI:1. 094 - 9. 528) were the regular monitoring promoting factors(all P < 0. 05). Antiviral therapy(OR = 0. 298,95% CI:0. 108 - 0. 822),virus gene mutation(OR = 0. 202,95% CI:0. 048 - 0. 856),and duration of disease(OR = 0. 340,95% CI:0. 122 - 0. 949) were related factors of HBeAg conversion(all P < 0. 05). The serum levels of ALT,ALB,AFP and HBV - DNA in the HBeAg negative regular monitoring group were (68 ± 34) IU/ L, (40 ± 12) g/ L, (23. 0 ± 5. 9) μg/ L, (2. 0 ± 1. 3)copies/ mL,respectively,which in the non - regular monitoring group were (126 ± 56) IU/ L,(35 ± 10) g/ L, (78. 0 ± 12. 8)μg/ L,(3. 9 ± 1. 7) copies/ mL,respectively,the differences were statistically significant (t = 2. 323, 2. 097,2. 109,2. 234,all P < 0. 05). Conclusion HBeAg negative patients is a key group to monitor and control disease progression. Regular laboratory monitoring is better. Medical staff should enhance patients' cognition education and improve disease control rate.

RESUMEN

<p><b>OBJECTIVE</b>To study the inhibitory activities of 3-O-β-chacotriosyl benzyl ursolate and its derivatives as potential new anti-influenza virus agents against the entry of H5N1 influenza viruses into the target cells.</p><p><b>METHODS</b>Four target compounds were designed and synthesized, which were structurally related to the lead compound 3-O-β-chacotriosyl methyl ursolate (1). The inhibitory activities of these compounds were tested at a cellular level psuedovirus system targeting H5N1 influenza viruse entry.</p><p><b>RESULTS AND CONCLUSION</b>The compounds 1b, 1c and 1d showed potent inhibitory activities against the entry of A/Thailand/Kan353/2004 pseudovirus into the target cells, and among them compound 1d showed the strongest inhibitory activity with an IC50 value of 0.96 ± 0.10 µmol/L. The structure-activity relationship analysis of these compounds indicated that when 17-COOH of ursolic acid was esterified, introduction of Me groups rather than aryl groups more strongly enhanced the inhibitory activity. Changing 17-COOH of ursolic acid into amide could increase the antiviral activity and decrease the cytotoxicity of the compounds in MDCK cells.</p>

RESUMEN

Objective To improve the stability and practicability of field liquid transfusion control system.Methods SPCE062A 's high accurate AD was used to acquire the dropping speed,and a new method for weight sensor 's self proofread was applied.Results The infrared photoelectric sensor was removed,so the monitoring part could work with any appropriate sensor.Conclusion The system cost is decreased and its stability and availability are enhanced.[Chinese Medical Equipment Journal,2008,29(2):66-67]
