Application value of Provider-Initiated HIV Testing and Counseling in dermatology / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the clinical application value of Provider-Initiated HIV Testing and Counseling (PITC) by analyzing the positive rate of HIV tests for people in need of PITC and that of routine HIV tests.</p><p><b>METHODS</b>We retrospectively analyzed the demographic and epidemiologic data about the patients seeking PITC services or undergoing routine HIV tests in Nanjing Drum Tower Hospital between January and December 2013.</p><p><b>RESULTS</b>The positive rate of initial HIV screening was 1.98% in the PITC group and 0.24% in the routine test group, while that of confirmed HIV was 0. 40% in the former and 0.07% in the latter, both with statistically significant differences between the two groups (P < 0.01). The positive rate of HIV was markedly higher in males than in females, particularly in the PITC group.</p><p><b>CONCLUSION</b>PITC has a high clinical value in HIV detection for targeted subjects and therefore deserves general application in dermatology.</p>

The distribution of angiotensin converting enzyme gene I/D polymorphism and its relationship with essential hypertension / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To observe the distribution character of angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism in Chinese population and its relationship with essential hypertension.</p><p><b>METHODS</b>Polymerase chain reaction (PCR) technique was used to detect the angiotensin converting enzyme gene I/D polymorphism in 2966 subjects of Kailuan Coal Mine, and further restriction analysis was performed.</p><p><b>RESULTS</b>The frequencies of ACE II, ID, DD genotypes in total study population were 41.5%, 38.4%, 20.1%, respectively. The DD genotypes in hypertensive group and that in control group were 18.9% and 21.0%, respectively. There was no significant difference between hypertensive group and control group (P>0.05). The same result was seen after stratification by age and gender in each group, respectively(P>0.05). The DD genotype and D allele showed a tendency to decrease with the increase of age (P<0.001).</p><p><b>CONCLUSION</b>The above results suggested that essential hypertension was not associated with ACE I/D polymorphism. The distributions of ACE genotype and allele varied with age, and the subjects with the character of DD genotype were at higher risk of early death.</p>
