Objective To investigate the relationship of carotid artery intima-media thickness(IMT) and blood pressure variation in patients with prehypertension. Methods Three hundred and ninety-two patients were selected as our subjects. Artery IMT was measured by Doppler ultrasonography. All patients were divided into carotid artery IMT group( n = 204 ),not carotid artery IMT group( n = 188 ) based on carotid IMT. Meanwhile,all patients were monitored by ambulatory blood pressure. Results (1)The indices of 24 h mean systolic blood pressure,systolic blood pressure variability and diastolic blood pressure variability in patients of carotid artery IMT group were(136. 85 ± 9. 67)mmHg,(4. 13 ± 0. 67)% ,(2. 97 ± 0. 45)% respectively, higher than those of Not carotid artery IMT group((121. 92 ± 6. 54)mmHg,(2. 64 ± 0. 86)% ,(2. 06 ± 0. 36)% ;t = 21. 08,5. 97,3. 32;P < 0. 05).(2)The rate of the carotid artery thickness increased with systolic blood pressure variability increasing( P = 0. 001). There were no significant correlations between rate of the carotid artery thickness and diastolic blood pressure variability,24 h mean diastolic blood pressure(P = 0. 435, 0. 126). The IMT thickening rate was higher when the average systolic blood pressure was greater(P = 0. 013). (3)Regression analysis indicated that carotid artery IMT was positively related with systolic blood pressure variability,high-sensitivity C-reactive protein,24 h mean systolic blood pressure,2-hour postprandial blood glouse. Conclusion Carotid artery IMT is independently associated with variation of blood pressure,especially with systolic blood pressure variability in prehypertension patients.

An adult patient with hypophosphatasia caused by compound heterozygous mutations in alkaline phosphatase,liver /bone /kidney(ALPL)gene was investigated through comprehensively reviewing the medical history and clinical records of the proband and her family members in order to better understand the disease.The proband and her older sister had mild decreased serum alkaline phosphatase level accompanied with frequently nontraumatic fractures at limbs and all the teeth fell off at the age of 20 and 7, respectively.Both of them carried a missense mutation c.407G>A(p.Arg136His)in exon 5 and a deletion mutation c.1318_1320delAAC(p.Asn440del)in exon 12 simultaneously.Other four family members were p.Arg136His mutation carriers and two members were p.Asn440del mutation carriers.We found that p.Asn440del mutation was associated with the oral disorders.In this family, compound heterozygous manifested more serious symptoms, while heterozygous showed relatively mild symptoms.In addition, it is necessary to differentiate it from primary osteoporosis and other diseases of disturbed bone mineralization.

Microglial cells are the resident immune cells of brain. The activated microglia produces a range of deleterious substances, which plays an important role in the inflammation of post-stroke, such as superoxide, nitric oxide, matrix metalloproteinases, etc. The activa-tion of microglia may involve triggering receptor expressed on myeloid cells-1, Toll-like receptors 4, peroxisome proliferator-activated re-ceptors, purinergic receptors, etc. Intervention targeted to microglial receptor is becoming a new strategy for ischemic stroke.

The value of combined application of both ECG-gated cine MRA and 3D-CEMRA in the detection of large intracranial aneurysms was evaluated and the findings were compared with those of conventional MRA and DSA. Twenty-four patients with 26 large intracranial aneurysms underwent MRI and DSA. All these aneurysms, diameter from 15 to 39 mm, were located at internal cerebral artery (n=12), vertebral artery (n=3), basilar artery (n=4), anterior cerebral artery (n=2), middle cerebral artery (n=2), anterior communicate artery (n=2) and posterior communicate artery (n=1). Thirteen cases of hematoma or cavernoma were studied as control group. All patients were examined on GE 1.5T MR system. ECG-gated cine MRA was performed with 2D multi-phase fast gradient-recalled echo sequence in a single section. All the images were analyzed with signal intensity VS time curve for differentiating intraaneurysmal blood flow from static tissue. The results were analyzed by statistic "t" test. 3D-CEMRA was performed with spoiled gradient-recalled echo and one dose of Gd-DTPA. All data was processed with multi-plannar reformat (MPR) and tomography for the demonstration of aneurysms in detail. All 26 aneurysms were demonstrated successfully by combined application of both cine MRA and 3D-CEMRA. Compared to DSA and conventional 3D-MOTSA, its sensitivity and specificity figures were both 100%. Cine MRA could differentiate the blood flow from the static tissue. The intensity VS time curves of intraaneurysmal blood flow offered fluctuating form and average signal change between systole and diastole period was about 89.8 +/- 37.4; However, under the control group, intraaneurysmal thrombus or cerebral hemorrhage or cavernomas had no significant signal change and the curves offered steady form with the average signal change being about 8.2 +/- 6.3. There was statistically significant difference between the intraaneurysmal blood flow and static tissue (P=0.025, <0.05). 3D-CEMRA was very useful in demonstrating the aneurysmal size, intraaneurysmal thrombus formation, neck and the detailed relationship of the aneurysm to the surrounding structures. It was concluded that the combined application of both cine MRA and 3D-CEMRA might be a valuable clinical tool for the detection of large intracranial aneurysms.
