ABSTRACT
<p><b>OBJECTIVE</b>To explore the efficacy of Ruiyun procedure for hemorrhoids (RPH) combined with Xiaozhiling injection in the treatment of hemorrhoids complicated with human immunodeficiency virus (HIV) infection and its influence on cellular immune function.</p><p><b>METHODS</b>Clinical data of 76 hemorrhoid patients, including 36 positive HIV and 40 negative HIV, undergoing RPH combined with Xiaozhiling injections in our center from January 2010 to December 2012 were retrospectively analyzed. Clinical efficacy and cellular immune function preoperative day 1, postoperative day 7, 30 were compared between positive and negative groups.</p><p><b>RESULTS</b>Recurrence rates of positive group and negative group postoperative 6 months were 22.2% (8/36) and 22.5% (9/40), postoperative 1 year were 30.6% (11/36) and 30.0% (12/40) without significant differences (all P>0.05). Morbidity of postoperative complication was also not significantly different between two groups (P>0.05). According to HIV classification, peripheral lymph cell ratio, CD4 count, CD4/CD8, white blood cell count and neutrophil ratio were not significantly different between preoperative day 1 and postoperative day 7 in both groups (all P>0.05). Decreasing velocity and amplitude of CD4 in both groups from high to low was HIV III, HIV II, HIV I, HIV-, while after 30 days the increase of CD4 from high to low was HIV-, HIV I, HIV II, HIV III, which were significantly different as compared to postoperative day 7 (all P<0.05).</p><p><b>CONCLUSIONS</b>RPH combined with Xiaozhiling injection in the treatment of hemorrhoids complicated with HIV infection is effective and safe. Postoperative inhibited cellular immune function can recover quickly.</p>

<p><b>OBJECTIVE</b>To observe the current changes of voltage-dependent potassium channel (Kv1.3 potassium channel) and calcium-activated potassium channel (IKCa1 potassium channel) in peripheral blood T-lymphocyte derived from hypertensive patients of Xinjiang Kazakh.</p><p><b>METHODS</b>Twenty randomly selected untreated Kazakh hypertensive patients and 20 Kazakh healthy subjects from Xinjiang were included in this study. T-lymphocytes were isolated from peripheral blood with magnetic cell sorting, the whole-cell currents of Kv1.3 and IKCa1 potassium channels were recorded with patch-clamp technique.</p><p><b>RESULTS</b>(1) The current density of Kv1.3 potassium channel was significantly higher in the hypertensive group [(280 ± 74) pA/pF (n = 39)] than that in the control group [(179 ± 51) pA/pF (n = 38), P < 0.01], while the membrane capacitance was similar between the two groups. (2) The current density of IKCa1 potassium channel was also significantly higher in the hypertensive group [(198 ± 44) pA/pF (n = 28)] than that in the control group [(124 ± 43) pA/pF (n = 26), P < 0.01], while the membrane capacitance was also similar between the two groups.</p><p><b>CONCLUSIONS</b>The T-lymphocytes Kv1.3 potassium channel and IKCa1 potassium channel current densities are higher in hypertensive patients in Xinjiang Kazakh suggesting a potential role of Kv1.3 and IKCa1 potassium channels activation in the pathophysiology of hypertension.</p>
