OBJECTIVE@#To identify the differentially expressed microRNAs (miRNAs) profiles of yang and yin syndromes in patients with acute ischemic stroke, and to provide the molecular basis of the classification of these two syndrome types in acute ischemic stroke patients.@*METHODS@#A microarray assay was performed to assess the expression pattern of miRNAs in the lymphocyte of acute ischemic stroke patients. Target genes for the deregulated miRNAs were predicated using the online bioinformatic algorithms and functional annotation via Kyoto encyclopedia of genes and genomes pathway analysis for miRNAs predicted targets was carried out. Based on the predicted target genes of differentially expressed miRNAs, the miRNA-gene-network and miRNA-pathway-network were constructed.@*RESULTS@#Yang score based on tongue texture, urine, dejecta, and appearance, etc. showed that clinical symptoms were distinct between yang and yin syndromes. There were significantly higher total leukocyte number and lower total protein level in patients with yang syndrome compared with those in patients with yin syndrome (P<0.05). Comprehensive miRNA analysis identified 36 unique down-regulated miRNAs in yang syndrome group, and 20 unique down-regulated and 2 unique up-regulated miRNAs in yin syndrome group. The key regulatory miRNAs, gene, and pathways in the yang syndrome were hsa-miR-93-5p and -320b, enabled homolog, the metabolic pathways and mitogen-activated protein kinase signaling pathways, respectively, while those in the yin syndrome were hsa-miR-424-5p and -106b-5p, CNOT4, hepatitis B and pathways in cancer, respectively.@*CONCLUSION@#These results offered insight into the molecular basis underlying the different pathogenesis of yang or yin syndrome, providing clues for the individualized therapeutic strategies of acute ischemic stroke.

To analyze the impact of hepatitis B virus (HBV) infection on liver function of patients after hematopoietic stem cell transplantation (HSCT), the transplantation outcome of 48 patients infected with HBV prior to transplantation among 185 patients received HSCT was investigated retrospectively. The results showed that during a follow-up for 6 months after HSCT, the alanine aminotransferase (ALT) peak average values of the patients with HBsAg(+), HBsAb(+) and control groups were (281.6 ± 414.6), (95.4 ± 79.9) and (65.1 ± 44.2) U/L, respectively. The incidences of abnormal liver function of the patients with HBsAg(+), HBsAb(+) and control groups were 61.54%, 40.00% and 30.23% respectively. There were no significant differences between any two groups (P > 0.05). The lethality of those patients at late period after transplantation was not related to HBV infection. The hepatocirrhosis and hepatocarcinoma caused by HBV infection have not become major problems in long-term survivors. It is concluded that in HBsAg(+) patients received HSCT, the damage of liver function is more severe than control group, possibly increasing the development of abnormal liver function. The measures against the liver function damage should be taken. The prophylactic administration of ganciclovir for virus may be effective to prevent the activation of HBV.

<p><b>OBJECTIVE</b>To study the correlation between carotid atherosclerosis (CAS) and hypertension.</p><p><b>METHODS</b>Color Doppler ultrasonography data of CAS were observed in 150 hypertension patients [as the hypertension group, including 70 patients in the phlegm-stasis syndrome (PSS) group and 80 in the non-PSS group] and 30 non-hypertension patients (as the control group). The difference of the CAS occurrence was compared among the three groups.</p><p><b>RESULTS</b>The incidence of CAS was higher in the PSS group and the non-PSS group than in the control group, showing statistical difference (P<0.01). Of them, it was higher in the PSS group than in the non-PSS group (P<0.05). Hard plaque dominated in the CAS plaque constitution in both the PSS group and the non-PSS group. Of them the soft plaque ratio was higher in the PSS group than in the non-PSS group, showing statistical difference (41.9% vs 11.4%, P<0.05). The CAS plaque distribution positions among the three groups (P>0.05). The inner diameters of the left and right common carotid artery, and the resistant indices of the left and right common carotid artery, the left internal carotid artery, and the left vertebral artery in the PSS group and the non-PSS group were higher than in the control group (P<0.05).</p><p><b>CONCLUSIONS</b>Hypertension patients are often accompanied with CAS of various degrees. Especially the soft plaque ratio of the CAS plaque was higher in those of PSS, indicating the possibility of target organs damage such as cerebral infarction was higher.</p>

<p><b>OBJECTIVE</b>To study the relationship between carotid atherosclerosis and cerebral infarction (CI).</p><p><b>METHODS</b>Between November 2008 and March 2009, 147 CI patients (CI group) and 48 patients with non-cerebrovascular diseases (control group) were enrolled from inpatients of Neurology Department of our hospital. The diagnostic criterion of thickened carotid intima was set as 1.0 mm<intima-media thickness (IMT) < 1.5 mm and that of carotid plaque was as IMT 1.5 mm. Carotid atherosclerosis was divided into three levels: normal intima, thickened intima, and plaque formation. The color Doppler ultrasonography data of carotid arteries in all patients were analyzed and the severity of carotid atherosclerosis was compared between the two groups.</p><p><b>RESULTS</b>In the CI group, 36 (24.5%) patients had normal carotid intima, 22 (15.0%) had thickened carotid intima, and 89 (60.5%) had carotid plaque. In the control group, 22 (45.8%) patients had normal carotid intima, 4 (8.3%) had thickened carotid intima, and 22 (45.8%) had carotid plaque. The severity of carotid atherosclerosis in the CI group was higher than that in the control group (P = 0.022). There was significant difference in the constitution of carotid plaque between the two groups (P = 0.001); the CI group mainly had the soft plaque (55/89, 61.8%), whereas the control group mainly had the hard plaque (17/22, 77.3%). The first three common locations of carotid plaque in both groups were carotid bifurcation (CI group: 73.7%; control group: 64.1%), common carotid artery (CI group: 20.4%; control group: 25.6%), and internal carotid artery (CI group: 5.9%; control group: 10.3%). The location of carotid plaque between the two groups was not significantly different (P = 0.438). There was no difference in the carotid inner diameter or resistance index between the two groups (P > 0.05).</p><p><b>CONCLUSIONS</b>Carotid atherosclerosis is to some extent able to reveal the atherosclerotic condition of cerebral arteries and act as an important predictor for the risk of CI. The color Doppler ultrasonography of carotid arteries can provide a convenient way for the prevention and treatment of CI.</p>
