OBJECTIVETo observe the clinical effects of Prunellae Oral Liquid (POL) on the size of thyroid with different states of thyroid function in patients of goiter.

METHODSFifty-six patients with hyperthyroidism, 24 with hypothyroidism and 18 with simple goiter were randomized into two groups. Group A treated by classical therapy, Group B by POL based on classical therapy. Size of thyroid of patients before and after treatment was measured by color ultrasonic Doppler and compared with the data obtained from 20 healthy subjects as control.

RESULTSSize of thyroid in all patients before treatment were obviously larger than that of normal control (P<0.01), but it reduced after treatment in both groups, especially in group B, in which it differed insignificantly to that in the normal control (P > 0.05).

CONCLUSIONCombined treatment of Chinese medicine (using POL) and Western medicine is superior to Western medicine alone in treating goiter with different states of thyroid function.

OBJECTIVETo explore Chinese medical syndrome distribution laws in coronary heart disease (CHD) patients of the Han nationality in Fuzhou city.

METHODSA questionnaire on Chinese medical syndrome was carried out in 507 patients with confirmed CHD from different regions of Fuzhou city. The correlation analyses of Chinese medical syndrome distribution laws, the Chinese medical syndrome types and complications, gender, age, the body mass index (BMI) were conducted.

RESULTSViewed from elements of deficiency in origin or excess in superficiality, blood stasis syndrome was the most often seen syndrome in patients with CHD (accounting for 63.1%), followed by qi deficiency syndrome (accounting for 59.4%) and phlegm turbidity syndrome (accounting for 45.6%). Among syndrome types, qi deficiency blood stasis syndrome was the most often seen syndrome (accounting for 12.2%), followed by qi deficiency, blood stasis and phlegm turbidity syndrome (accounting for 9.1%), and qi deficiency and phlegm turbidity syndrome (accounting for 8.1%). The distribution of various Chinese medical syndrome types showed significant difference in different ages (P<0.05), but no obvious difference was shown in different genders, body mass index, or complications (P>0.05).

CONCLUSIONSBlood stasis, qi deficiency, and phlegm turbidity were the basic pathogeneses of CHD patients of the Han nationality in Fuzhou city. Syndrome with intermingled blood stasis, qi deficiency, and phlegm turbidity was the main Chinese medical syndrome pattern. The combination of syndrome showed certain regularity.

Our previous results have demonstrated that insulin reduces myocardial ischemia/reperfusion (MI/R) injury and increases the postischemic myocardial functions via activating the cellular survival signaling, i.e., phosphatidylinositol 3-kinase (PI3-K)-Akt-endothelial nitric oxide synthase (eNOS)-nitric oxide (NO) cascade. However, it remains largely controversial whether c-Jun NH2-terminal kinase (JNK) is involved in the effects of insulin on MI/R injury. Therefore, the aims of the present study were to investigate the role of JNK, especially the cross-talk between JNK and previously expatiated Akt signaling, in the protective effect of insulin on I/R myocardium. Isolated hearts from adult Sprague-Dawley rats were subjected to 30 min of regional ischemia and followed by 2 or 4 h of reperfusion (n=6). The hearts were pretreated with PI3-K inhibitor LY294002, or phosphorylated-JNK inhibitor SP600125, respectively, then perfused retrogradely with insulin, and the mechanical functions of hearts, including the heart rate (HR), left ventricular developed pressure (LVDP) and instantaneous first derivation of left ventricular pressure (+/-LVdp/dt(max)) were measured. At the end of reperfusion, the infarct size (IS) and apoptotic index (AI) were examined. MI/R caused significant cardiac dysfunction and myocardial apoptosis (strong TUNEL-positive staining). Compared with the control group, insulin treatment in MI/R rats exerted protective effects as evidenced by reduced myocardial IS [(28.9 +/- 2.0)% vs (45.0 +/- 4.0) %, n=6, P<0.01], inhibited cardiomyocyte apoptosis [decreased AI: (16.0 +/- 0.7) % vs (27.6 +/- 1.3) %, n=6, P<0.01] and improved recovery of cardiac systolic/diastolic function (including LVDP and +/-LVdp/dt(max)) at the end of reperfusion. Moreover, insulin resulted in 1.7-fold and 1.5-fold increases in Akt and JNK phosphorylation in I/R myocardium, respectively (n=6, P<0.05). Inhibition of Akt activation with LY294002 abolished, and inhibition of JNK activation with SP600125 enhanced the cardioprotection by insulin, respectively. And the abolishment by LY294002 could be partly converted by SP600125 pretreatment. In addition, SP600125 also decreased the Akt phosphorylation (n=6, P<0.05). These results demonstrate that insulin simultaneously activates both Akt and JNK, and the latter further increases the phosphorylation of Akt which attenuates MI/R injury and improves heart function; this cross-talk between Akt and JNK in the insulin signaling is involved in insulin-induced cardioprotective effect.

OBJECTIVETo analyze differentially expressed metastasis-associated proteins in Adenoid cystic carcinoma cell lines of human salivary gland by proteomics.

METHODSProtein expression alterations of ACC-2 and ACC-M cells were described by 2-D gels. After image analysis by software, proteins of interest were excised from the gels and identified by matrix assisted laser desorption ionization time-of-flight mass spectrometer.

RESULTS12 protein spots showed significantly differential expression patterns between two cell lines. In the identified protein candidates, transketolase, modulator recognition factor 2, Dim1p homolog, splicing factor (arginine/serine-rich 9) and v-Ha-ras l oncogene were all lowly expressed in the poorly metastatic ACC-2 cell and significantly upregulated in highly metastatic ACC-M cell, while type I collagen pro alpha and tumor necrosis factor (ligand) superfamily member 4 showed a high expression in ACC-2 cells and a low expression in ACC-M cells. Pirin (spot 6) just appears in ACC-2 cell and was not detectable in ACC-M cell, while retinal homeobox protein was just detected in ACC-M cell and did not appear in ACC-2 cell.

CONCLUSIONSThe proteins may be involved in the adenoid cystic carcinoma lung metastasis through different mechanisms. Our work may contribute to discover diagnostic markers and therapeutic targets.

OBJECTIVETo investigate the effects of glucocorticoid receptor antagonist-M8046 on the behavior and the cyclooxygenase-2/prostaglandin E2( COX-2/PGE2) expression in spinal cord dorsal horn and dorsal root ganglia (DRG) in chronic constrictive injury (CCI) rats.

METHODSOne hundred and forty-four male SD rats were randomly divided into 4 groups, 36 rats in each group: Sham operation group (Sham), chronic constrictive group (CCI), M8046 treated group (M8046) and solvent controlled group (Sc). M8046 3 mg/(kg x d) intraperitoneal injection was given after operation in group M8046. Paw thennal withdrawal (PTWL) and paw mechanical withdrawal threshold (PMWT) of rats were measured on 2 pre-operative and 1, 3, 7, 10, 14 post-operative days. The spinal cord and L15 DRG of the operated side was removed at 3, 7, 14 days after surgery. The change of COX-2 and PGE2 expression was determined by immunohistochemical staining and ELISA separately.

RESULTSPTWL and PMWT in CCI group were significantly lower than those in Sham group on every post-operative day (P < 0.05). PTWL and PMWT in M8046 group were significantly higher than those in CCI group on 7, 10, 14 post-operative day (P < 0.05). In spinal dorsal horn, the level of COX-2 and PGE2 expression in CCI group was significantly higher than that in Sham group (P < 0.05). M8046 could significantly attenuate the activation of COX-2 and PGE2 induced by CCI (P < 0.05). The expression of COX-2 and PGE2 in DRG was similar to that in spinal dorsal horn.

CONCLUSIONThe effects of M8046 ameliorate the CCI-induced neuropathic pain may be related to attenuate the expression of COX-2 and PGE2 in spinal cord and DRG.

To approach the effect of CCAAT/enhancer binding proteins (C/EBPs) on un-terminal differentiation of HL-60 cells after treatment with Arsenic Trioxide ( As_2O_3) . Methods The changes of cell morphology were observed by Wright staining, the alteration in the cell proliferation was determined by WST1 experiment and the NBT reduction assay was used to detect the differentiation condition of cells, determination and analysis cell cycle. The expressions of C/EBP? and C/EBP? mRNA in HL-60 cells exposed to ATRA and As_2O_3 were assayed by semi-quantitative RT-PCR. Results It was found that ATRA could up- regulate the mRNA expression of C/EBP? obviously, but down-regulate the mRNA expression of C/EBP?. As_2O_3 could up-regulate the mRNA expression of C/EBP? lightly, down-regulate the expression of C/EBP?. Conclusion Both of ATRA and As_2O_3 can down-regulate the mRNA expression of C/EBP?,but there is no significant difference between these two groups,ATRA and As2O3 can up- regulate the mRNA expression of C/EBP?, with significant differences (P

BACKGROUNDRight ventricular (RV) dysfunction ensues due to rheumatic mitral stenosis (RMS). The evaluation of RV function is clinically important for the diagnosis, treatment, and follow-up for patients with different degrees of RMS. The purpose of this study was to determine whether the 64-slice multi-detector row computed tomography (64-slice MDCT) can assess the RV function in RMS with high accuracy and reproducibility when compared to MR imaging (MRI).

METHODSRight ventricular end-diastolic and end-systolic volumes (RV-EDV and RV-ESV), stroke volume (RV-SV), ejection fraction (RV-EF), cardiac output (RV-CO), and wall mass (RV-Mass) were measured with dedicated cardiac analysis software on 64-slice MDCT and compared with values measured with MRI in 43 consecutive patients with RMS. Agreement between MRI and 64-MDCT results were compared with Bland and Altman analysis and linear regression analysis. Repeated measurements were performed to determine intraobserver and interobserver variability.

RESULTSNo significant differences were revealed in calculated RV function parameters between the two methods. RV-EDV, RV-ESV, RV-SV, RV-EF, RV-CO, and RV-Mass by 64-slice MDCT were similar to those by MRI (P > 0.05). There were good correlations (r = 0.98, 0.97, 0.96, 0.96, 0.95 and 0.77, respectively) and close agreement (bias = -0.2 ml, -1.0 ml, 0.8 ml, 0.5%, 26.1 ml, and 0.5 g, respectively, P > 0.05). The variability in 64-slice MDCT measurements was similar to that in MRI values.

CONCLUSIONECG-gated 64-slice MDCT could assess the RV function in RMS with high accuracy and reproducibility when compared to MRI.

OBJECTIVETo explore the expression of vascular endothelial growth factor (VEGF) and its receptors (flt-1 and flk-1) in the retina of retinopathy of prematurity (ROP), and its relation to the alteration of retinal blood vessels.

METHODSEighty-six newborn Sprague-Dawley rats were randomly divided into hyperoxia and air groups, then each group was further divided into 1, 3, 7 and 14 days subgroups. The rats in hyperoxia group inhaled 75% oxygen and ROP model was thus set up. These animals were sacrificed respectively after 1, 3, 7 and 14 days, then the retinal endothelial cells were marked by CD34 to observe the change of retinal blood vessels. The expression of VEGF, flt-1 and flk-1 in the retina was measured by immunohistochemistry.

RESULTSThe retinal capillary density index (RCDI) in control group increased as days went on (F = 21.589, P < 0.01, but it was the least on the 7th day in hyperoxia group, after the rats had been returned to air for 7 days, RCDI increased significantly (F = 67.885, P < 0.01); In the control group, the expression of VEGF and flk-1 was the strongest in the retina on the 7th day, the result had significant difference as compared with the 1st and 14th day (P < 0.05). The expression of VEGF and flk-1 on the 7th day in hyperoxia group was weaker than that of control group (P < 0.05). But on the 14th day in hyperoxia group, they were stronger than that of control (P < 0.05). The localization of the expression of flt-1 was changed when blood vessels altered, but there was no significant difference in expression intensity as a whole (P > 0.05).

CONCLUSIONWhen the premature retina was exposed to hyperoxia, the expression of VEGF and flk-1 was reduced, and retinal blood vessels were also decreased; but the expression of VEGF and flk-1 was stronger in retina when premature rats were exposed to relative hypoxia, and the retinal blood vessels also increased significantly. It is concluded that VEGF and flk-1 may play important roles in the development of retinal blood vessels and its change in ROP. However, flt-1 has less effect compared with flk-1.
