0.05). Homogenous or inhomogenous high signal in aplastic anemia were detected with decreased T 1 value. Homogenous iso-intensity was revealed in acute pure red cell aplasia with normal T 1 value. Aplastic anemia and acute pure red cell aplasia had a homogenous signal on T 2WI, their T 1 value showed significant difference (P

Objective To evaluate the MRI in the diagnosis of aplastic anemia (AA) and MRI changes after therapy. Methods MR imaging of lumber spine in 16 patients with AA proved pathologically were performed on 0.5 T superconductive MR unit with T 1WI, T 2WI, and STIR, slice thick 5 mm, slice gap 1 mm, matrix 180?256. Thirty cases of normal volunteers were examined as control group. Lumber spines of the two groups were studied by observation of MRI findings, measurement of the T 1 relaxation value. In AA group, the percentage of the hypointense signal areas in the centrum was calculated. Results Three patterns were classified by MR appearance in lumber spine of our cases. MR findings of pattern 1 (2 cases) were hyperintense on T 1WI, isointense on T 2WI, and hypointense on STIR, and all two cases were acute aplastic anemia (AAA). In pattern 2 (7 cases), a few irregular hypointense signals appeared in the background of hyperintense signal on all 3 sequences, and 5 of them were AAA. Pattern 3 (7 cases) demonstrated mixed irregular shape of hyperintense and hypointense signals, all 7 cases were chronic aplastic anemia (CAA). The percentage of the area of hypointense signal in AAA was significantly smaller than that in CAA (t=30 00, P

Objective To evaluate the diagnostic value of MRI and X ray and to analyze MRI and X ray characteristics in Med anemia Methods MRI was performed in thoracic spine,lumbar spine, sacral spine,pelvis,and superior femurs in 15 patients with pathologically proved Med anemia with T 1WI and T 2WI Seven of them were examined on X ray Twenty volunteers were examined on MR as control group The authors analyzed the manifestations of MRI in the Med anemia, including abnormality of signal intensity of bone marrow,T 1 value,vertebral alteration of size and shaped, spinal cord compression due to epidural extramedullary haematopoiesis, and compared with the findings of bone on X ray Results In the control group, bone marrow showed an inhomogeneous iso signal intensity with band shaped, triangular or motley high signal intensity in the middle or back part of the vertebra, neck of the femur on T 1WI and a homogeneous iso signal intensity on T 2WI in the vertebra, pelvis, and superior femur All cases with Med anemia had low homogenous signal intensity in the bone marrow of the vertebra, pelvis and superior femur on T 1WI but had no alterations on T 2WI The spinal cord was constricted resulting from protruding crushed vertebra with bullet like shape in 4 cases The soft tissue masses, confirmed as extramedullary haematopoiesis by operation, were demonstrated in 4 cases Among 7 cases with X ray examinations, 2 cases showed normal on X ray but abnormal bone marrow on MRI, another 5 cases demonstrated bone alteration including osteoporosis, widening of striations, enlargement of ribs and vertebras T 1 value showed (897 4?75 43)ms in the Med anemia group and (401 5?28 1)ms in the control group with significant statistical difference ( P

Platelet membrane glycoproteins play a key role in the processes of platelet adhesion,activation and aggregation and thrombosis.Many studies have shown that platelet membrane glycoprotein gene polymorphisms are associated with ischemic stroke.This article reviews the relationship between platelet membrane glycoprotein gene polymorphisms and ischemic stroke.

Objective To explore the effects of botulinum toxin type A (BTX-A) on the F-waves of the tibial nerve and the walking ability of stroke patients.Methods Twenty stroke patients with spastic hemiplegia of a lower limb were randomly divided into experimental and control groups with 10 patients in each group.All received four weeks of conventional rehabilitation,including walking training,balance training and muscle strength training.In the experimental group,a total of 300 IU of BTX-A was injected into the gastrocnemius (200 IU) and soleus muscles (100 IU)before the start of routine rehabilitation,guided by using the electrical stimulation.Muscle tone was assessed using the modified Ashworth scale(MAS).Walking ability was assessed with the timed up and go test (TUGT) and a 10 m free walking test.F-wave parameters were recorded in the tibial nerve before,two weeks and four weeks after the injection.Results In the experimental group there was a significant difference in F-wave amplitude between those recorded before treatment and after two weeks of treatment.The control group showed no statistically significant difference.In experimental group there was also a statistically significant difference in triceps muscle tension before and after treatment which was not observed in the control group.Walking ability improved significantly in both groups.Conclusions Local injection of BTX-A into the lower limbs can reduce the F-wave amplitudes of spinal cord motor neurons.BTX-A injection combined with rehabilitation training can significantly improve the walking ability of stroke patients.

Objective To explore the correlation between serum level of cystatin C and coronary slow flow (CSF).Methods Thirty-four patients with CSF were enrolled in CSF group and thirty-five patients with normal coronary flow and angiographically normal coronary arteries were enrolled in control group.Coronary flow patterns was assessed by corrected thrombolysis in myocardial infarction (TIMI) frame count.The change of serum high sensitivity C-reactive protein,uric acid,cystatin C were measured.Results There was no significant difference between two groups with respect to gender,age,history of smoking,prevalence of hypertension and diabetes mellitus,family history of coronary heart disease,low density lipoprotein,α-lipoprotein (P ＞0.05).Compared with control group,the level of serum high sensitivity C-reactive protein,cystatin C,uric acid in CSF group were obviously higher [(4.85 ± 6.39) mg/L vs.(2.55 ± 2.18) mg/L,(0.87 ± 0.22) mg/L vs.(0.75 ± 0.16) mg/L,(329.68 ± 85.46) μ mol/L vs.(278.97 ± 76.74) μ mol/L] (P ＜ 0.05 or ＜ 0.01).Logistic regression analysis showed that cystatin C increased as independent risk factors for CSF (P =0.002,OR =0.009).Conclusion High level of cystatin C may play an important role in the occurrence and development of CSF.

OBJECTIVE:To systematically review the efficacy and safety of pirfenidone in the treatment of idiopathic pulmo-nary fibrosis (IPF),and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Cochrane Library, PubMed,EMBase,CJFD,CBM,VIP Database and Wanfang Database,randomized controlled trials (RCT) about the efficacy and safety of pirfenidone (test group) versus placebo (control group) in the treatment of IPF were collected,and Meta-analysis was performed by using Rev Man 5.1.7 software after data extracting and quality evaluating by modified Jadad. RESULTS:Totally 4 RCTs were enrolled,involving 1 153 patients. Results of Meta-analysis showed the decrease value of lung capacity [WMD=0.39,95%CI(0.16,0.61), P<0.001] and decrease value of the percentage of forced vital capacity to expected value [RR=0.68, 95%CI(0.53,0.87),P=0.002] in test group were lower than control group,there was significant difference between 2 groups;there was no significant difference in the lowest oxygen saturation [WMD=0.53,95%CI(-0.78,1.84),P=0.43] between 2 groups,however,the results of subgroup analysis showed the remission degree of 1 200 mg/d PFD for the decrease of lowest oxy-gen saturation was superior to placebo group,there was significant difference between 2 groups [WMD=1.72,95%CI(1.33,2.10), P<0.001],but therewas no significant difference between the remission degree of 1800 mg/d and placebo;and there was no signifi-cant difference in the incidence of adverse reactions between 2 groups [RR=1.70,95%CI(0.46,6.31),P=0.43],but the incidence of photosensitivity veactions in test group was significantly higher than that of control group,there was significant difference [RR=9.35,95%CI(4.23,20.67),P<0.001]. CONCLUSIONS:The efficacy of pirfenidone in the treatment of IPF is good,but the inci-dence of photosensitivity reactions should be noticed.

Objective To evaluate MRI findings and X ray appearance in primary myelofibrosis (PMF) in marrow of lumber vertebra and pelvis. Methods Eleven cases of PMF with integrated clinical and pathology data were collected. All cases were examined with X ray and MRI simultaneously. The imaging findings of PMF were studied and compared with that of normal group. The MRI findings and X ray appearance of cases with PMF were evaluated and compared with each other to find their good quality, the shortcoming, and the relationships. Results X ray appearance in the plain film in cases with PMF: There were no abnormal findings in lumbar vertebra, iliac bone, and superior segment of femur in 5 of 11 cases. Blurred bone trabecula and ground glass changes in bone marrow were found in 3 of 11 cases. In another 3 cases, the bone trabeculas were obscured, tightly closed or mixed together, and the density of bone marrow were widespreadly high, and the difference in it couldn′t be distinguished. MRI findings in cases with PMF: MRI findings in different parts of lumbar vertebrae, iliac bone, and femur superior segments in all 11 cases were consistent. Compared with the control group, both images on T 1 and T 2 weighted spin echo displayed diffusely and well distributed lower signal intensity in 6 of 11 cases, but displayed scattered spot and patchy lowersignals in 5 of 11 cases in all parts of bone marrow including lumbar vertebra, iliac bone, and superior segment of femur. The extents of lower marrow signal intensity varied in different cases. The high signal in femoral head and greater trochanters remained unchanged as that of subcutaneous fat in 4 of 11 cases. The positive rate was 54.6%(6/11)in X ray findings, but 100%(11/11)in MRI appearances. Conclusion MRI has greater value than X ray in the early diagnosis of PMF. The early diagnostic value of X ray plain film for PMF is limited.
