Objective To investigate the effect of nicorandil pretreatment on myocardial mitochondria in a rabbit model of myocardial ischemia-reperfusion (I/R). Methods Tirty-two healthy male New Zealand white rabbits weighing 2.0-2.5 kg aged 4 months were randomly allocated into 4 groups ( n = 8 each): Ⅰ group sham operation (group S); Ⅱ group I/R; Ⅲ group nicorandil pretreatment (group N) and Ⅳ group nicorandil + 5 hydroxydecanoic acid (group N + 5-HD). Myocardial I/R was induced by 30 min occlusion of left circumflex coronary artery followed by 120 min reperfusion. In group N and N + 5-HD a bolus of nicorandil 100 μg/kg was given iv at 10 min before myocardial ischemia followed by continuous infusion at 10 μg· kg-1 · min-1 until the beginning of myocardial ischemia. In group Ⅳ a bolus of 5-HD 5 mg/kg was injected iv at 20 min before myocardial ischemia.The animals were sacrificed at the end of 120 min reperfusion. The mitochondrial membrane potential was measured by flow cytometry using JC-1 fluorescence probe as indicator. Bcl-2, Bax and cytochrome c protein expression was determined by immuno-histochemistry. Myocardial ultrastructure was examined with transmission electron microscope. Results Red fluovescence intensity indicating normal live cells was significantly higher, the green fluorescence intensity indicating apoptotic cells was lower and red/green fluorescence intensity ratio was higher; the Bcl-2/Bax ratio was significantly higher and cytochrome c protein expression lower in group N than in group I/R.5-HD administration negated the protective effect of nicorandil pretreatment against myocardial I/R injury. Conclusion Nicorandil stabilizes mitochondrial membrane potential, decreases cytochrome c protein releasing, and suppresses mitochondrial apoptotic signal transduction by opening the mito-KATP channels.

BACKGROUND:IPS e. max Press porcelain crown has been widely used in clinical restoration because of its aesthetic effect and biological properties. OBJECTIVE:To explore the effect of IPS e. max Press porcelain crown in esthetic restoration of anterior teeth in terms of marginal adaptation and color match. METHODS:Total y 52 patients with 138 defective anterior teeth (20 males and 32 females, 18-45 years old, including 62 anterior tooth defects, 46 tooth traumas, 30 denticles) were divided into two groups randomly:treatment group (26 cases) and control group (26 cases) were given IPS e.max Press porcelain crown and conditional Co-Cr al oy handcuffed ceramic crowns, respectively. Al the cases were asked for a second visit in 1 week after restoration, and the integrity of ceramic veneer, marginal adaptation, gingival health and color match were evaluated during 6-month and 2-year fol ow-ups. RESULTS AND CONCLUSION:The degrees of satisfaction on the color, shape and adaptation in the treatment group were al higher than those in the control group (P<0.05). At 6 months after restoration, the marginal adaptation, gingival health and color match in the treatment group were al better than those in the control group (P<0.05). At 2 years after restoration, there was also a significant difference in the marginal adaptation, gingival health and color match between the two groups (P<0.05). IPS e.max Press porcelain crown has the advantages of aesthetics and biological characteristics, so it can be used as an ideal restoration method for esthetic restoration of anterior teeth.

Objective Neuropsychiatric systemic lupus erythematosus ( SLE) is a common complication of SLE, whose path-ogenesis is not yet clear but associated with the alteration of cerebral blood flow ( CBF) in some studies.This study was to investigate the CBF alteration in SLE patients without overt neuropsychiatric symptoms by arterial spin labeling ( ASL) MRI. Methods Twenty-eight SLE patients without overt neuropsychiatric symptoms and 30 age-and sex-matched healthy controls underwent conventional MRI and ASL examinations, and all received such neuropsychologic tests as number connecting test-A ( NCT-A ) , digit symbol test ( DST ) , self-rating anxiety scale ( SAS ) , and self-rating depression scale ( SDS) .Independent sample-t test was used to detect the mean CBF in the whole brain, gray matter, and white matter of the SLE patients and healthy controls.The voxel-wise CBF maps of the two groups of subjects were further analyzed with the SPM8 software to compare the regional CBF between the two groups, followed by evaluation of the correlation between the regional CBF values and clinical markers. Results In comparison with the healthy controls, the SLE pa-tients showed significantly reduced CBF in the gray matter (40.5 ±3.7 vs 37.3 ±6.5, P=0.028) and the whole brain (38.0 ±3.5 vs 35.1 ±6.1, P=0.032), especially in the supplementary motor area and the adjacent middle cingulate, anterior cingulate, left medial frontal gyrus, left inferior frontal gyrus, and left insula (P<0.05, FWE corrected).The NCT-A score was negatively correlated with the CBF values of the left medial frontal gyrus (r=-0.402, P=0.032) and left inferior frontal gyrus (r=-0.382, P=0.045) of the SLE patients. Conclusion ASL and MRI showed significantly reduced cerebral blood flow in the SLE patient without overt neu-ropsychiatric manifestations, which was correlated with the change of the patient's cognitive function.

OBJECTIVETo analyze the relationship between Duffy antigen receptor for chemokines (DARC) and the metastasis potential in human breast cancer. METHODS Breast cancer tissue sections from 75 patients, grouped according to the local lymph node status were examined immunohistochemically for protein level of DARC. Microvessel density (MVD) was counted by endothelial cells immunostained using anti-CD34 antibody.

RESULTSStrong positive DARC immunostaining in lymph node negative and positive groups was detected in 31 cases (81.6%) and 18 cases (48.6%), respectively (P < 0.01). MVD was (35.67 +/- 17.96)/HP and (53.38 +/- 20.29)/HP in DARC strong positive and less positive cases (P < 0.01). In those patients with lung, bone, hepatic distant metastasis (13 cases), 9 cases (69.2%) were DARC less positive, 4 cases (30.8%) were DARC strong positive. The correlation coefficient was -0.412 between DARC expression and MVD and the corresponding value was -0.346 between DARC expression and lymph node status and -0.333 between DARC expression and distant metastasis in breast cancer.

CONCLUSIONDARC may play a negative role in the process of neoangiogenesis, and probably has an association with the lymph node status.

OBJECTIVETo observe the clinical efficacy of modified Huanglian Wendan Decoction (HWD) in treating senile mild cognitive impairment (MCI) of turbid-phlegm blocking orifice syndrome.

METHODSWith a block randomized, double-blinded and controlled design adopted, the 64 patients of MCI selected from December 2007 to February 2009 were randomly and equally assigned to two groups. The treatment group was treated with HWD in dose of 200 mL, twice a day; the control group was given Aniracetam 0.2 g (for patients over 70-years-old, 0.1 g) three times a day. And the illusive medicine in dosage-form of capsule/decoction simulated to that used in the opposite group was applied. The medication and observation lasted for three months. Chinese medicine syndrome, cognition capacity (by MMSE), laboratory indexes [acetylcholine (Ach), superoxide dismutase (SOD), malondialdehyde (MDA)] and safety related indexes in patients were observed.

RESULTSAfter treatment, MMSE score increased in both groups, but the increment in the treatment group was significantly higher than that in the control group (P<0.01); Chinese medicine syndrome estimated by scoring showed that after treatment, all scores of syndromes, excepting the expectoration, were improved in the treatment group with the post-treatment scores significantly lower than those in the control group respectively (P<0.05 or P<0.01); while in the control group, lowering of scores only showed in some symptoms such as poor memory, heavy head or dizziness, and heavy sensation in limbs and body. Serum levels of Ach and SOD decreased and MDA increased in both groups after treatment, but the change of Ach was more significant in the treatment group (P<0.01). No obvious adverse reactions were found during the treatment.

CONCLUSIONFor treatment of MCI, HWD shows effects in improving patients' symptoms, cognition capacity and elevating serum Ach content better than that of Aniracetam; and with effects for raising SOD activity and reducing MDA level similar to those of Aniracetam.

Results Carried on the comprehensive therapy regarding the above patients, the brain malignant encephalocele rate in the SBI group and the pure group was 59.55% (53/89) and 13.04%(3/23) respectively, there was significant statistics differences in the two groups,1 level and 2 level of high-risk factors group of brain malignant encephalocele rate was 40.74% (11/27) and 53.57% (15/28) respectively, the difference was not obvious statistics significance, 2 level and 3 level of high-risk factors group of brain malignant eneephalocele rate was 53.57%(15/28) and 79.41%(27/34) respectively, the difference was obvious statistics significance. Conclusions The SBI's high-risk factors are the important factors affecting severe craniocerebral injury encephalocele. Taking adequate pre-operative assessment, carrying a comprehensive treatment on the patients combine with high-risk factors of SBI can greatly reduced the incidence of brain malignant encephalocele during surgical operation if the high-risk factors of SBI is controlled.

OBJECTIVETo explore how adjustment of the negative and neutral emotion excitement contribute to the well-being of middle-aged and aged adults in their health, intelligence, working and living.

METHODSTwenty-five middle-aged and aged participants performed recognition tasks of schematic facial representations of positive, neutral and negative emotions and also Chinese characters (equivalent to happy, thinking and fear).

RESULTSThe main effects of the facial recognition task occurred in the left temporal-parietal area (40 to 80 ms), bilateral parietal-occipital and temporal-parietal area (160-180 ms and 310-340 ms). The effects of stimulation with the 3 Chinese characters were found in the anterior region (375-475 ms), posterior region (195-255 ms), and whole scalp region (135-175 ms and 275-355 ms). There were no significant interactive effects between schematic facial recognition and stimulation with Chinese characters.

CONCLUSIONPositive emotional excitement may promote the well-being of the adults in their health, intelligence, working performance and living.

Chrysanthemum coronarium is an economically important plant in Asia, and used medicinally, ornamentally and as a vegetable. In April 2017, leaf spot disease on C. coronarium was observed in Shiyan, Hubei, China. A single-spore isolate was obtained and identified based on morphology and sequence analysis using four regions (rDNA ITS, GAPDH, EF-1α, and RPB2). The results indicated that the fungus is Alternaria argyranthemi. The pathogenicity tests revealed that the species could cause severe leaf spot and blight disease on the host. This is the first report of leaf spot disease on C. coronarium caused by A. argyranthemi in the world, which is also a new record of Alternaria species in China.
