AlM: To explore the clinical significances and changes of related parameters of corneal endothelial cell in keratouveitis patients before and after treatment.
METHODS:Fifty-two keratouveitis patients ( 52 eyes ) diagnosed and treated in our hospital from October 2012 to December 2013 were collected. Before and after treatment, the related parameters of corneal endothelial cell in all patients were measured with non - contact corneal specular microscope and these parameters were statistically analyzed.
RESULTS: Compared with the normal group, obvious endothelial cell edema and great variation was observed in diseased group. The shorter duration of treatment, the better the recovery of endothelial cells and the fewer cells lose. Conversely, the longer the healing of normal hexagonal cell ratio was smaller, the larger the coefficient of variation. Before and after treatment, the differences of each parameter were statistical significance (P<0. 05).
CONCLUSlON: The functional recovery of corneal endothelial cell has directly relation with disease times.

Objective To analyze the genetic model of attention deficit hyperactivity disorder(ADHD).Methods The segregation analysis and polygenic multiple threshold model were used to prove the polygenic model and to estimate the heritability and recurrence risk of ADHD in each degree relatives.Results 1. The average heritability of ADHD was (102.47?9.78)%;2.The first-degree relatives of probands were in high risk for ADHD(23.0%)compared with colony prevalence rate(2.6%). The ADHD prevalence of each degree relatives rapidly decreased with the increased magnitude of consanguineous relationship of each degree relatives and ADHD probands. Conclusions The genetic model of ADHD is the most likely polygenic inheritance with major genes, which suggested that the genetic factor might play an important role in the liability variance of ADHD.Apart from the involvement of multiple genes,each gene contributes a small additive effect,and the major genes may be involved as well.

Objective:To investigate the characteristics of lymphocyte subsets in peripheral blood of patients with immunoglobulin G4-related disease (IgG4-RD) and the correlation between T helper 17 cell (Th17)/regulatory T cells (Treg) cell imbalance and cytokines.Methods:A total of 31 patients with IgG4-RD who were admitted to the Rheumatology and Immunology Department of the Second Hospital of Shanxi Medical University from January 2016 to June 2020 were included. We collected their clinical and laboratory data, and selected 30 age and sex matched healthy people as the control group. Flow cytometry was used to detect the percentage and absolute number of lymphocyte subsets [T, B, natural killer cell (NK), CD4 +T, CD8 +T] and CD4 +T subsets [Th1, Th2, Th17, CD4 +CD25 +forkhead box protein 3 (Foxp3) +Treg] in peripheral blood of IgG4-RD patients and healthy controls. The serum interleukin (IL)-2, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor (TNF)-α and interferon (IFN)-γ levels in the IgG4-RD patients were measured by cytometric bead array (CBA). Correlation between Th17/Treg ratio and disease-related indicators was also analyzed. We used χ2 test, Mann-Whitney U test and Spearman correlation analysis for statistical analysis. Results:① The percentage of CD4 +T cells in the peripheral blood of IgG4-RD patients was higher than that of healthy controls [45.00%(33.97%, 51.48%) vs 39.36%(33.78%, 43.30%), Z=-2.142, P<0.05]. ② The percentage and absolute number of Th17 cells was increased in IgG4-RD patients [1.13%(0.70%, 1.55%) vs 0.77%(0.43%, 1.07%), Z=-2.229, P<0.05; 7.90(5.20, 12.23) cells/μl vs 5.60(3.12, 8.47) cells/μl, Z=-2.568, P<0.05], while the percentage of Treg cells was decreased [3.37%(2.82%, 5.65%) vs 4.96%(4.18%, 6.34%), Z=-2.986, P<0.01]. But the number of Treg cells showed no difference between the two groups. ③ Th17/Treg ratio was significantly increased in IgG4-RD patients [0.29(0.16, 0.46) vs 0.15(0.08, 0.23), Z=-3.119, P<0.01], and it was positively correlated with IgG4-RD response index score ( r=0.491, P<0.01). ④ Serum IL-6 [13.72(9.29, 26.06) pg/ml vs 2.23(1.94, 3.10) pg/ml, Z=-4.815, P<0.01], IL-10 [5.46(4.28, 15.38) pg/ml vs 1.81(1.59, 2.02) pg/ml, Z=-5.298, P<0.01], TNF-α [4.25(1.47, 7.26) pg/ml vs 1.15(1.05, 1.45) pg/ml, Z=-3.146, P<0.01] and IFN-γ [3.89(1.76, 6.61) pg/ml vs 1.41(1.24, 1.65) pg/ml, Z=-3.172, P<0.01] in IgG4-RD group were significantly higher than those in healthy control group. Moreover, Th17/Treg ratio was negatively correlated with IL-2 level ( r=-0.554, P<0.05). Conclusion:Th17/Treg disorder exists in IgG4-RD patients, and it is related to disease activity, indicating that Th17/Treg imbalance may be an important mechanism in IgG4-RD. IL-2 plays an important role in regulating Th17/Treg balance and may be a potential immunotherapy target in future.

A 48-year-old man presented with a 4-day history of fever and 10-year history of papulovesicles on the face, neck, trunk and limbs which had been aggravated 10 days prior to the presentation.Skin biopsy showed a dermal infiltration of numerous small- to medium-sized atypical lymphocytes, which was mainly located around blood vessels or appendages, with the involvement of subcutaneous fat tissue and destruction of blood vessels. The infiltrating atypical cells stained positive for CD45RO, CD8, CD56, T-cell intracellular antigen-1, granzyme B, Epstein-Barr virus-encoded small nuclear RNAs (EBER), but negative for CD20, CD79a, CD3, CD4 or CD30. Cytoplasmic CD3ε was also observed in these cells. Laboratory examinations on admission revealed a progressive decrease in peripheral erythrocytes, white cells and platelets, persistent increase in serum aminotransferase and bilirubin, and decline in serum fibrinogen and hypertriglyceridemia. The B-mode ultrasound of the abdomen showed hepatosplenomegaly. Based on the above findings,the diagnosis was made as extranodal nasal type NK/T-cell lymphoma of skin complicated by hemophagocytic syndrome.
