The Current Status of Informatization Construction and Application in Provincial Disease Prevention and Control Institutions / 医学信息学杂志

The paper issues questionnaires to investigate the current status of informatization construction and application in 32 provincial disease prevention and control institutions of China,summarizes the current status of informatization organization and management,standard planning,capital input and allocation,analyzes the problems existing in the process of disease control informatization construction,focuses on the discussion of imbalanced regional development,insufficient capital input,lack of informatization personnel,and lack of informatization security awareness,and proposes corresponding suggestions and countermeasures.

Diagnostic Value of Cerebrospinal Fluid T-SPOT.TB for Tuberculousis Meningitis in China / 生物医学与环境科学（英文）

The aim of this study was to evaluate the diagnostic value of the cerebrospinal fluid (CSF) T-SPOT.TB test for the diagnosis of TB meningitis (TBM). A retrospective analysis of 96 patients with manifested meningitis was conducted; T-SPOT.TB test was performed for diagnosing TBM to determine the diagnostic sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). A receiver operating characteristic (ROC) curve was also drawn to assess the diagnostic accuracy. The sensitivity, specificity, PPV, and NPV of CSF T-SPOT.TB test were 97.8%, 78.0%, 80.3%, and 97.5%, respectively, for 52 patients (54.2%) of the 96 enrolled patients. The area under the curve (AUC) was 0.910, and the sensitivities of CSF T-SPOT.TB for patients with stages I, II, and III of TBM were 96.7%, 97.2%, and 98.9%, respectively. CSF T-SPOT.TB test is a rapid and accurate diagnostic method with higher sensitivity and specificity for diagnosing TBM.

Compensatory sweating after restricting or lowering the level of sympathectomy: a systematic review and meta-analysis

OBJECTIVE: To compare compensatory sweating after lowering or restricting the level of sympathectomy. METHOD: A systematic review and meta-analysis were conducted of all randomized controlled trials published in English that compared compensatory sweating after lowering or restricting the level of sympathectomy. The Cochrane collaboration tool was used to assess the risk of bias, and the Mantel-Haenszel odds ratio method was used for the meta-analysis. RESULTS: A total of 11 randomized controlled trials were included, including a total of 1079 patients. Five of the randomized controlled trials studied restricting the level of sympathectomy, and the remaining six studied lowering the level of sympathectomy. CONCLUSIONS: The compiled randomized controlled trial results published so far in the literature do not support the claims that lowering or restricting the level of sympathetic ablation results in less compensatory sweating. .

Cytotoxicity of T cells transduced with WT1 peptide-specific T-cell receptor gene against human lung cancer cells in vitro / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the cytotoxicity of normal CD8(+) T lymphocytes retrovirally transduced with WT1 peptide-specific T-cell receptor (TCR) genes against human lung cancer cells.</p><p><b>METHODS</b>HLA-A*2402-restricted and WT1 peptide-specific TCR-α/β genes were cloned from a cytotoxic T lymphocyte clone and inserted into a retroviral TCR expression vector. The cytotoxicity of normal peripheral CD8⁺ T cells transduced with the WT1-TCR genes against human lung cancer cells was evaluated using a standard ⁵¹Cr release assay.</p><p><b>RESULTS</b>The WT1-TCR gene-modified T cells recognized the peptide-pulsed target cells but not the non-pulsed cells. TCR-redirected CD8⁺ T cells lysed WT1-overexpressing human lung cancer cells in an HLA-A*2402-restricted manner, but did not kill normal cells positively expressing HLA-A*2402.</p><p><b>CONCLUSION</b>These data demonstrate the feasibility of adoptive immunotherapy with TCR-redirected T cell for the treatment of lung cancer.</p>
