Objective To investigate the pathological features of blood vessel inflammation in facioscapulohumeral muscular dystrophy ( FSHD ) and the role of vasculitis on the pathogenesis of FSHD. Methods The clinical manifestations and myopathological features of 26 FSHD patients were retrospectively analyzed and summarized. All of the patients were divided into 2 groups; inflammatory infiltration group and non-inflammatory infiltration group. The latter was further divided into 3 subgroups;endomysial inflammation subgroup, perivasculitis subgroup and transmural vasculitis subgroup.Immunohistochemical staining were carried out in inflammatory infiltration group with anti-CD3, anti-CD4,anti-CD8,anti-CD20 and anti-SMA antibody. The control group was composed of 10 dermatomyositis ( DM)cases and 10 polymyositis ( PM) cases. Results The age of onset was (25. 2 ± 12. 6) years old and the average course was (7. 8 ±7. 3) years. The sex ratio of male to female was 1.6: 1. Five of them had family history. The main clinical features were progressive weakness and atrophy of facial, shoulder girdles and proximal upper limbs muscles. The lower distal limbs and (or) lower distal limbs and pelvic girdle muscles were involved in 18 cases. The main pathological features were shown as followed. Seventeen of them had focal inflammatory cell infiltration, including endomysial inflammation (4/17) , perivasculitis (7/17) , and transmural vasculitis (6/17). Immunohistochemical staining confirmed the major types of inflammatory cells were CD4* T lymphocytes and CD20B lymphocytes, which was familiar with DM. While in PM, CD8+ T lymphocytes were dominant The proportionality of residual muscle fibers obviously decreased in inflammatory infiltration group ( 48. 0% ± 23. 6% ) than non-inflammatory infiltration group ( 94. 3% ±3. 1% , T = 198. 000, P = 0. 000). As to CK levels, there were no significant deviation. Conclusions Obvious inflammatory cell infiltration can be seen in FSHD, the locations of inflammatory cells are endomyosium inflammation, perivasculitis and transmural vasculitis. Transmural vasculitis indicates vascular pathological factor may have something to do with pathogenesis of FSHD.

Objective To investigate the association between levels of serum alanine aminotransferase (ALT) and the risks of metabolic syndrome in middle-aged and elderly Chinese. Methods After excluding subjects with known liver disease, excess alcohol consumption and serum ALT≥40 IU/L,1 664 subjects aged 40 years or older from Baoshan Community, Shanghai were recruited to undergo questionnaire interview, anthropometric measurements, and fasting blood sampling. Biochemical features were evaluated and the metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria with modification on waist circumference cutoff which is more appropriate for an Asian population. Results Increased ALT levels were associated with more unfavorable metabolic risk profiles. The prevalence rates of the metabolic syndrome in participants with increasing ALT quartiles were 29. 2% , 38. 0% , 44.9% , and 62. 9% , respectively (P for trend <0. 01 ). ALT concentrations were significantly elevated with increasing number of the metabolic syndrome components (P for trend<0.01). Serum ALT levels were significantly associated with the risks of metabolic syndrome and most of its components in a dose-response manner. As compared with participants in the first ALT quartile, the risks of metabolic syndrome were increased by 146% , central obesity by 204% , hypertension by 35% , high triglycerides by 133% , and hyperglycemia by 72% in participants of the fourth ALT quartile. Conclusions A high-normal serum ALT level was significantly associated with an increased risk of the metabolic syndrome in middle-aged and elderly Chinese.
