Expression and significance of Teff subsets, Treg and their cytokines in patients with vitiligo / 中国医师杂志

Objective:To investigate the expression and clinical significance of effector T cell (Teff), regulatory T cell (Treg) and their cytokines in patients with vitiligo.Methods:84 patients with vitiligo (38 cases in stable stage, 46 cases in advanced stage) who were admitted to the Dermatology Department of the Dezhou People's Hospital between June 2018 and June 2019 and 30 healthy people (control group) were enrolled in the study. The levels of Teff subsets and Treg cells in peripheral blood were detected by flow cytometry. The levels of Teff subsets and Treg cells-associated cytokines were detected by enzyme-linked immunosorbent assay (ELISA). The relationship between Teff subsets and Treg cells levels in peripheral blood, relationship between Teff subgroups, Treg cells-associated cytokines and course of vitiligo, skin lesion area were analyzed.Results:The levels of T helper cell (Th)17 and Th22 in peripheral blood of vitiligo group were significantly higher than those of control group, while levels of Treg cells were significantly lower than control group ( P<0.05). Compared with the stable vitiligo group, the levels of Th17 and Th22 in peripheral blood were higher and levels of Treg cells were lower in the advanced vitiligo group ( P<0.05). Treg cell level was negatively correlated with Th17 cell level ( r=-0.303, P=0.001), and negatively correlated with Th22 cell level ( r=-0.200, P=0.033). The levels of serum interleukin (IL)-17 and IL-22 in vitiligo group were significantly higher than those in control group, while the level of transforming growth factor-β (TGF-β) was significantly lower than that in control group ( P<0.05). Compared with the stable vitiligo group, levels of serum IL-17 and IL-22 were higher and level of TGF-β was lower in the advanced vitiligo group ( P<0.05). Correlation analysis showed that levels of IL-17 and IL-22 were positively correlated with skin lesion area ( r=0.361, 0.288, P<0.05), and level of TGF-β was negatively correlated with skin lesion area ( r=-0.312, P<0.05). Conclusions:Teff/Treg cells are unbalanced in patients with vitiligo, showing obvious shift to Teff subsets. The progression of vitiligo may be related to Teff subsets and Treg cells-associated cytokines.

Beneficial effects of position on patent foramen ovale-induced right-to-left shunt by contrast transcranial Doppler ultrasonography / 中华超声影像学杂志

Objective To investigate the influence on right-to-left shunt (RLS) of patent foramen ovale with contrast transcranial Dopple (cTCD) in different positions.Methods 276 consecutive patients included ischemic cerebrovascular disease (ICVD),migraine,episodic vertigo and syncope.They underwent cTCD at rest and after Valsalva maneuver in 4 positions:upright sitting,supine,left lateral decubitus and right lateral decubitus,in random order.RLS was graded 0 (no microbubbles detected),1 (1-10microbubbles),2 (＞ 10 microbubbles but no curtain),and 3 (curtain,shower of microbubbles).Meanwhile,each patients was examined by contrast transthoracic echocardiography(cTTE),contrast transesophageal echocardiography (cTEE) or right heart catheterization.Results RLS detection rate was 48.2％ (133/276)through cTCD.They were also confirmed patent foramen ovale by 82 cases in cTTE,28 cases in cTEE,and 23 patients in right heart catheterization.At rest,RLS detection rate and microbubbles of 4 positions had no significant difference (P ＞0.05).After the Valsalva maneuver,RLS detection rate and microbubbles of each position were significantly higher than at rest (P ＜0.001),and the RLS detection rate and microbubbles in upright sitting were higher than that at rest(P ＜0.05).Conclusions RLS is best detected in the upright sitting position with Valsalva maneuver with cTCD.Upright sitting detection helps to improve the detection rate and microbubbles of RLS.

Study on Impacts of Immune Regulation with Spleen-strengthening and Kidney-tonifying Method among Advanced Malignant Tumor Patients / 世界科学技术-中医药现代化

This study was aimed to evaluate impacts on immune regulation with spleen-strengthening and kidney-tonifying method among advanced malignant tumor patients. The enrolled advanced malignant tumor patients were randomly divided into the control group and the treatment group. The control group was treated with conventional treatment plan. The treatment group was treated with spleen-strengthening and kidney-tonifying Chinese herbs on the basis of conventional treatment plan for three months. Clinical effect, integral of clinical symptom (ICS), T-lym-phocyte subsets, and drug safety index were observed and detected before and after treatment. The results showed that the effective rate and response rate in the control group were 31.1% and 71.1%, respectively. And the effective rate and response rate in the treatment group were 54.2% and 85.4%, respectively. The treatment group was better than the control group (P< 0.05). Compared to the control group, the treatment group had obvious regulation on T-lymphocyte subsets. The improvement on ICS in the treatment group was better than the control group (P < 0.05). There was no obvious adverse reaction with the application of Chinese herbs. It was concluded that the spleen-strengthening and kidney-tonifying method can improve clinical effect, life of quality, and reduce adverse reaction a-mong advanced malignant tumor patients. Its mechanism may be through the regulation of immune function.
