Stroke is one of the major diseases that threaten human health, early diagnosis and treatment are very important for stroke. Carotid intima-media thickness (CIMT) is measured noninvasively to diagnosis stroke, and it is a independent predictor for stroke because its thickening can timely predict the incidence and development of stroke. As an important predictor of cardiovascular disease, more and more attention is played on CIMT. In this review, we will make a summary on the important role of CIMT in stroke and the mechanisms of carotid intima-media thickening in stroke as well as the potential use of traditional Chinese medicine in treating carotid intima-media thickening.

Objective To explore the effect of glutamine(Gln) on expression of nuclear factor kappa B(NF-?B) and heat shock protein 70(HSP70) in brain of young rats induced by lipopolysaccharide(LPS).Methods Ten days old Wistar rats were randomly divided into 3 groups by injection intraperitoneally different agonts,LPS group,normal saline control group(NS group) and Gln group(Gln 1.346 g/kg,1 hour before LPS).NF-?B and HSP70 distribution and expression in brain were deteted by immunohistochemistry.The levels of HSP70 in rats brain induced by LPS were detected by Western blot.SPSS 12.0 software was used.Results The nuclei of neuron in cerebral cortex in LPS group obviously cleared at 6 hours.The positive stain of nuclei in Gln group at 2 hours could not be seen.The stain of nuclei in cerebral cortex was weakened in LPS group at 6 hours by immunohistochemistry.HSP70 protein expression decreased with the measurement of Western blot,especially at 24 hours.HSP70 expression in LPS group was similar as that in NS group.The stain of nuclei in neuron in Gln group at 2 hours increased.It also showed the amount of protein expression increased in Western blot in group Gln at 2,6,12,24 hours(Pa

In order to investigate the genetic basis of morphological variation of tetraploid plantlets of Atractylodes macrocephala, diploid plantlets were taken as experimental material, sterile filtration colchicine was used to soak 0.5-1.0 cm long buds. The difference between morphology and stomatal of diploid and tetraploid of A. macrocephala was compared, and genome polymorphism was explored by AFLP. The results showed that the buds dipped in 0.1% colchicine solution for 36 h was optimal conditions to induce tetraploid of A. macrocephala with induction rate of 32.0%. Morphological indexes such as leaf area index, leaf length and width, the density of stomas and the number of chloroplast of tetraploid were distinctly different from diploid. Four hundred and fifty-one bands ranging with 80-500 bp were amplified with 24 pairs of primers, the rate of polymorphism was 32.59%. These amplification sites of diploid were different from tetraploid of A. macrocephala, and the differences in morphology of them were reflected in the DNA polymorphism.

Objective To investigate the effects of atorvastatin on the experimental autoimmune encephalomyelitis(EAE)and the underlying mechanism of immunoregulation.Method The Wistar rats were used to establish EAE model.After oral administration of 2, 8 mg? kg~(1)?d~(1)of atorvastatin, the rats were examined for the development of neurological signs, changes of histopathology and the expression of IL-4 and MMP-9.Result Though high dose treatment with atorvastatin, the frequency of EAE attacks degreased from 76.67% to 33.33%(P=0.008);the extent of inflammation degreased from 3.2?1.1 to 1.3?0.4(P=0.01);and the number of MMP-9 positive cells degreased from 37?7 to 26?5(P= 0.001), the expression of IL-4 could be increased from(0.35?0.12)ng/ml to(0.68?0.23)ng/ml (P=0.05).Conclusion Atorvastatin can reduce the inflammation and produce the recover of the neurological harm because of the changes of MMP-9 and IL-4.

Objective To study the clinical application of quantitative ultrasound(QUS) which evaluate skeletal status of children and adolescents.Methods Subjects were children and adolescents aged 0-18 years old.Tibia/radial bone strength was obtained using QUS.Children who were younger than 2 years old only were measured at midpiece of tibia,and children who were older than 2 years old were measu-red at midpiece of tibia and radius.At the same time,calcium in peripheral blood was measured by the method of atomic absorption.Results 1.Radial and tibial bone strength presented nonlinear growth with age in healthy children and adolescents.2.Bone strengths of different anatomic-sites were different and the disparity rate of evaluation at different anatomic sites was 30.1%.3.The bone strength of the children who had some risk factors that could induce decrease of bone strength or had some diseases of bone metabolism was lower than healthy children.Composition of low bone strength children was 71.1% in high risk children,and was 47.9% in those who had some symptom or physical sign of calcium deficiency.4.Composition of low bone strength children was 44.2% in those who had normal peripheral blood calcium,and composition of normal bone strength children in those who had low peripheral blood calcium was 59.7%.The 2 methods had no correlation.Conclusions QUS is a quite useful technique in evaluation skeletal status of children and adolescents,and is sensitive for high risk children.It is necessary to measure radius and tibia,and consider blood calcium and bone strength to evaluate practical level of calcium and nutritional state of children.

OBJECTIVETo compare the difference of the clinical efficacy on common peroneal palsy between the comprehensive therapy of electroacupuncture, moxibustion and moving cupping method and western medication.

METHODSNinety cases of common peroneal nerve palsy were randomized into a comprehensive therapy group and a western medication group, 45 cases in each one. In the comprehensive therapy group, electroacupuncture was applied to Yanglingquan (GB 34), Zusanli (ST 36), Xuanzhong (GB 39), Jiexi (ST 41), Taichong (LR 3), Zulinqi (GB 41) and the others, combined with warm moxibustion and moving cupping on the lateral side of the affected leg. The comprehensive therapy was used once a day. In the western medication group, vitamin B1 , 10 mg each time, 3 times a day; and mecobalamine, 0. 5 mg each time, three times a day were prescribed for oral administration. In the two groups, 15 days made one session, and the efficacy was observed after 2 sessions treatment.

RESULTSThe total effective rate of the improvement of sensory function and motor nerve function was 97. 8% (44/45) in the comprehensive therapy group and was 82. 2% (37/ 45) in the western medication. The efficacy in the comprehensive therapy group was better than that of the western medication (P<0. 01). The electrophysiological examination showed that the amplitude of motor conduction of deep peroneal nerve and that of sensory conduction of surficial peroneal nerve after treatment were improved remarkably as compared with those before treatment in the comprehensive therapy group (both P<0. 05). The amplitude of motor conduction of deep peroneal nerve was improved significantly in the comprehensive therapy group as compared with that in the western medication group (P<0. 05).

CONCLUSIONThe comprehensive therapy of electroacupuncture, moxibustion and moving cupping method achieves the significant efficacy on common peroneal nerve palsy as compared with western medication.
