ObjectiveTo evaluate the value of early secretory antigenic target 6 (ESAT-6) in monocytes of cerebrospinal fluid (CSF) in the early diagnosis and judgment of the tuberculous meningitis (TBM). MethodsForty cases with TBM (TBM group) and 40 patients with other meningitis patients (control group,9 cases with purulent meningitis,24 cases with viral meningitis,3 cases with cryptococcal meningitis,3 cases with cerebral cysticercosis, 1 case with neurosyphyilis) were involved in this study.Conventional examination of CSF was inspected after admission, and the ESAT-6 in monocytes of CSF was detected by immunocytochemical stain. ResultsThe positive rate of ESAT-6 was 24％ in TBM group and 0 in control group (P ＜ 0.01 ). In ROC curve, if the rate of ESAT-6 ≥8.5％ judged as positive, and ＜ 8.5％ judged as negative, 35 patients of TBM group and 4 patients of control group were ESAT-6 positive. The sensitivity of the ESAT-6 in the diagnosis of TBM was 87.5％, and the specificity of TBM was 90.0％. Thirty patients in TBM group were not given anti-tuberculosis drug treatment, and the positive rate of ESAT-6 was 93.3％ (28/30) before treatment, and was 46.7％ (14/30) after treatment of 2 weeks (P =0.000).ConclusionsESAT-6 in monocytes of CSF detected by immunocytochemical stain has higher sensitivity and specificity in the diagnosis of TBM in early stage. Observing the positive rate of ESAT-6 dynamicly has practical value in judgment the severity of TBM.

Objective To investigate the clinical and molecular pathological features of limb-girdle muscular dystrophy 2A (LGMD2A) of Chinese patients. Methods Thirty cases of LGMD with excluding LGMD2B were included in this study. The muscle specimens were performed by a standard series methods of histochemistry, enzymohistochemistry, immunohistochemistry and Western blot. The clinical and molecular pathological features of LGMD2A were retrospective analyzed. Results Five cases with no or only trace expression of calpain-3 protein were diagnosed as calpainopathy (LGMD2A) by Western blot analysis. The age of onset of these 5 patients ranged from 10 to 45 years and the duration of the disease were about 2-10 years. Proximal muscles weakness and atrophy of lower limbs were predominantly involved. In all patients,symptoms progressed slowly. The ambulation could be retained for many years but running and jumping were impaired early. The serum creatine kinase level was elevated moderately to markedly. Electromyography showed myopathic patterns in all cases. Two siblings had similar symptoms indicating autosomai recessive inherited pattern. Pathologically, there was marked variation in fibre size and most small fibres were round. Some necrotic and regenerating fibers were seen. Fibres with centrally placed nuclei can be found frequently. No infiltrations of inflammatory cells were seen. Lobulated fibers were observed in 2 patients by NADH-TR stain. The expression of dystrophin, caveolin-3, α-, β-, γ- and δ-sarcoglycan protein were normally staining of 5 LGMD2A patients' specimens by immunohistochemistry. Two patients had reduced staining of dysferlin by immunohistochemistry study. Conclusions Clinical and pathological characteristics of our 5 LGMD2A patients are consistent with typical muscular dystrophy features reported in other countries. Identification of calpian-3 deletion by Western blot is essential for the diagnosis of calpainopathy.

BACKGROUND:Fibrin glue introduced into calcium phosphate cement has not been confirmed whether this way could overcome the compressive limits and the low degradation of calcium phosphate cement and to modify the biological properties of calcium phosphate cement. OBJECTIVE:To explore the mechanical and biological properties of calcium phosphate cement/fibrin glue at different powder/liquid ratio for bone regeneration in vitro. METHODS:Calcium phosphate cement and fibrin glue were mixed at ratios of 1:1, 3:1, 5:1 (mL/g), and the pure calcium phosphate cement served as controls. Setting time, scanning electron microscope and the biomechanical test were used to analyze the composite scaffold structure, physical performance and the mechanical properties. Passage 3 osteoblasts were respectively inoculated on the material surface of the four groups, and pure cells served as blank controls. celladhesion, proliferation and alkaline phosphatase activity were observed. RESULTS AND CONCLUSION:The initial and final setting time of calcium phosphate cement/fibrin glue at 1:1 and 3:1 (mL/g) was higher than that in the control group (P<0.05), while the initial and final setting time of calcium phosphate cement/fibrin glue at 5:1 (mL/g) was lower than that of the control group (P<0.05). Scanning electron microscope showed smoother and denser surface of composite scaffolds compared with the pure calcium phosphate cement. The aperture of the composite scaffolds was decreased with the increasing concentration of fibrin glue. The compressive strength of composite scaffolds at 3:1 and 5:1 was higher than that of the control group (P<0.05), while the modulus of the composite scaffolds at 1:1, 3:1, 5:1 was higher than that of the control group (P<0.05). celladhesion, proliferation and alkaline phosphatase activity showed no difference among the three composite scaffold and control groups, but al higher than the blank control group (P<0.05). These findings indicate that fibrin glue introduced into calcium phosphate cement can overcome the low-strength limits of calcium phosphate cement, and maintain the good biological properties of calcium phosphate cement for bone regeneration.
