Clinical characteristics and distribution of peripheral T lymphocyte subsets in patients with schistosomal hepatic diseases in Suzhou City / 中国血吸虫病防治杂志

Objective To investigate the clinical characteristics and the distribution of peripheral blood T lymphocyte sub-sets in patients with schistosomal hepatic cirrhosis in Suzhou City. Methods A total of 32 inpatients with liver diseases due to advanced schistosomiasis at the Department of Infectious Diseases, The First Affiliated Hospital of Soochow University from January 2016 to January 2018 were recruited and assigned into the infection and non-infection groups according to presence of co-infections, and 20 old healthy volunteers served as controls. Venous blood samples were collected on the day of admission, and the proportions of CD4+ T cells, CD8+ T cells, regulatory T (Treg) cells and Th17 cells were detected in peripheral blood using flow cytometry. Results Most patients with liver disorders due to advanced schistosomiasis were admitted to hospital in Suzhou City because of portal hypertension-associated complications, with a high prevalence of co-infections (59.38%, 19/32). The proportions of peripheral CD4+ and CD8+ T cells and Th17 cells were all significantly lower in patients with liver disorders due to advanced schistosomiasis than in controls (t = −5.111, −4.470 and −2.749, all P < 0.05), and a higher proportion of Treg cells was detected in patients than in controls (t = 5.628, P < 0.05). In addition, there were significant differences among the infection group, non-infection group and controls in terms of the percentage of CD4+ T cells, CD8+ T cells, Th17 cells and Treg cells (F = 15.837, 16.594, 9.290 and 27.866, all P < 0.05). Conclusion Portal hypertension-associated complications are predominantly seen in patients with liver diseases due to advanced schistosomiasis at admission in Suzhou City, and co-infections are common. Imbalance of peripheral T cell subsets is detected in patients with liver diseases due to advanced schistosomiasis in Suzhou City.

HIV DNA and immune alteration during successful HAART.

BACKGROUND: Highly Active Antiretroviral therapy (HAART) can effectively reduce the viral load to undetectable levels in most HIV-infected patients. However, some patients may still experience impaired immunologic response associated with increased risk of disease progression and death. OBJECTIVE: The objective of this study was to assess the impact of the HIV DNA load on the immune alteration during successful HAART. METHODS: 40 chronic HIV-infected adults initiating HAART were followed for 24 months. The CD4 count, HIV viral load, HIV DNA load, and levels of γ-cytokines IL-2, IL-7 and IL-21 were monitored at baseline (month 0), month 6, 12, 18 and 24 following HAART initiation. RESULTS: The plasma viral load decreased significantly and remained below the detection limits after six months treatment. Likely the HIV DNA load decreased significantly in both cells during 12 months, was undetectable in CD14 monocytes after 18 months, but remained higher in CD3+ T cells during all the follow up. In addition, the HIV DNA load correlated positively between T cells and monocytes in 10 patients who maintained higher HIV DNA load in both cells during 12 months. The CD4 count, IL-2, and IL-21 levels increased significantly during 12 months, whereas IL-7 decreased significantly during 18 months, regardless of the HIV DNA load in T cells. Patients with CD4 count below 200/µl maintained higher HIV DNA load and showed lower increase in CD4 count compared to patients with CD4 count above 200/µl. In patients showing undetectable HIV DNA load in both cells, neither IL-2 nor IL-21 correlated with the CD4 count even after 24 months despite their partial restoration. CONCLUSION: These results suggest that the HIV DNA load could continuously hamper the CD4 restoration and γ-cytokines functional activities during HAART. This action seemed to be more severe in patients with pre-HAART CD4 count below 200/µl. The CD14 monocytes may contribute to this action as source of T cell infection both before and during HAART.

Effect of Transcutaneous Electric Nerve Stimulation and Physical Therapy on Shoulder Pain after Stroke / 中国康复理论与实践

@#ObjectiveTo observe the effect of transcutaneous electric nerve stimulation (TENS) and physical therapy on shoulder pain after stroke. Methods60 patients of shoulder pain after stroke were randomly divided into treatment group (30 cases) and control group(30 cases). The patients in the treatment group were treated with TENS and physical therapy. The cases in the control group were treated with TENS only. All patients were evaluated with visual analogous score of pain (VAS) and Fugl-Meyer measure (FM) before and after treatment. ResultsThe scores of VAS and FM improved more significantly in treatment group than in control group(P<0.01).ConclusionTranscutaneous electric nerve stimulation combined with physical therapy showed more effective on shoulder pain after stroke.
