Objective To explore the relationship between blood pressure and hemorrhagic cerebral infarction. Methods Retrospectively reviewed clinical data of 242 patients with acute cerebral infarction, then all patients with hemorrhagic cerebral infarction were selected. The distributions of different level of blood pressure (>180/110mm Hg;90/70~180/110mm Hg;<90/70mm Hg) were compared between the patients with or without hemorrhagic cerebral infarction, as the same, different prognosis were compared among the patients with hemorrhagic cerebral infarction based on the different level of blood pressure. Results Of the total patients with acute cerebral infarction,4. 1%(10) presented with blood pressure<90/70mm Hg,88. 0%(213) with blood pressure 90/70~180/110mm Hg and 7.9%(19) with blood pressure>180/110mm Hg. In all the patients,20 cases(8. 3%) with hemorrhagic cerebral infarction,among which,60.0%(12) patients with blood pressure>180/110mm Hg and with 7 cases died, 10.0%(2) patients with blood pressure<90/70mm Hg and with 1 case died,30.0%(6) patients with blood pressure 90/70~180/110mm Hg and with 2 cases died. The distribution of patients with blood pressure>180/110mm Hg in those two type of cerebral infraction were statistically significant (P=0. 000) ,the ratio seemed higher in patients with hemorrhagic cerebral infarction, and among the patients with hemorrhagic cerebral infarction, the distribution of prognosis were the same statistically significant based on the diffetent level of blood pressure, among which, patients with blood pressure>180/110mm Hg(P =0.041) or<90/70mm Hg(P =0.037) seemed like to have a higher mortality. Conclusion Severe high blood pressure(>180/110mm Hg) should be one of the high risk factors for patients with hemorrhagic cerebral infarction,when blood pressure>180/110 mm Hg or <90/70mm Hg happened in the pathogenesis, patients always be with poor outcome. So, making proper control strategy of blood pressure for patients with hemorrhagic cerebral infarction was with significance to defend its' happening and prognosis' improvement.

AIM: To investigate the effects of advanced glycation end products (AGEs) on the expression of plasminogen activator inhibitor-1 (PAI-1) in rat mesangial cells and its relationship with extracellular matrix accumulation. METHODS: Rat mesangial cells were treated with AGE-modified bovine serum albumin or native bovine serum albumin. Normal mesangial cells without any treatments were used as control. Fibronectin (FN), collagen Ⅳ, PAI-1 protein contents were detected by ELISA. PAI-1 mRNA was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: AGEs (0-200 mg/L) did not influence mesangial cells proliferation, but stimulated FN , collagen IV and PAI-1 contents in mesangial cell cultured medium in different degrees. AGEs also increased PAI-1 mRNA expression. CONCLUSION: AGEs increase the expression of PAI-1 in rat mesangial cells. AGEs may reduce ECM degradation through increasing PAI-1 expression, which may be one of the mechanisms of ECM accumulation in diabetic nephropathy.

Objective To investigate the relationship between phosphatidylinositol 3-kinase catalytic subunit α(PIK3CA) expression and the incidence and different pathological grade of gastric cancer, and the mechanism thereof. Meth-ods The expressions of PIK3CA, serine/threonine protein kinase (pAkt) and cell proliferation associated nuclear antigen (ki-67) in gastric carcinoma and adjacent tissues and normal gastric mucosa were detected by immunohistochemical method. The relationship between expressions of PIK3CA, pAkt and ki-67 and tumorigenesis was analyzed. The expressions of PIK3CA, pAkt and ki-67 in different pathological conditions of gastric tissues were analyzed. The relationship between tu-mor pathologic classification and differentiation were analyzed too. Results There were significantly higher expressions of PIK3CA, pAkt and ki-67 in gastric cancer (P<0.05), which were the highest in the poorly differentiated gastric adenocarci-noma (P<0.05). There were a positive correlation between expressions of PIK3CA, pAkt and ki-67 and different pathologi-cal levels of gastric carcinoma and adjacent tissues and normal gastric tissues (P<0.05). Conclusion PIK3CA may be the initiating factor of PI3K/Akt signaling pathway, which induced phosphorylation of Akt and activation PI3K/Akt signaling pathway, promoting the proliferation, invasion and metastasis of gastric adenocarcinoma.

CircRNA is a single-stranded, covalently closed non-coding RNA, whose mechanism mainly involves sponge adsorption of micro RNA (miRNA), regulation of protein transcription and post-transcriptional levels, interaction with RNA-binding proteins and few coding proteins of circRNA. Meanwhile, because of its abundant expression, highly conserved and dynamic changes, circRNAs have promising applications such as becoming biomarkers of diseases, developing circRNA vaccines and gene editing therapies for circRNAs. Cardiovascular diseases are the leading cause of death from diseases worldwide, and existing therapeutic approaches can delay the development of heart diseases, but are still limited by the unknown pathogenesis and therapeutic targets. Many studies have reported the mechanistic link between circRNAs and cardiac diseases, therefore, this review is to explain the progress of circRNA research in cardiovascular diseases and to illustrate the three clinical applications in which circRNAs are currently involved.

OBJECTIVETo observe the regional homogeneity (ReHo) of resting-state brain function in the healthy subjects of gastric distention treated with acupuncture at the back- and front- points of the stomach, Weishu (BL 21) and Zhongwan (CV 12) and the correlation with gastric motility so as to explore the mechanism on the central integration of the front- and back- points of the stomach.
METHODSThe crossover test design was adopted. Twenty-four healthy subjects were assigned to a Weishu group, a Zhongwan group and a combined-point group separately, 8 cases in each one in each of the three times. Totally, 24 subjects were included in each group. Under the water load condition, the subjects received acupuncture at Weishu (BL 21), Zhongwan (CV 12) and the combined Weishu (BL 21) and Zhongwan (CV 12). Before and after each acupuncture, the resting-state brain functional magnetic resonance imaging (fMRI) scan and electrogastrogram (EGG) test were applied. The ReHo value was calculated in the collected fMRI imaging data. The changes in ReHo values were analyzed and compared before and after acupuncture in each group, as well as among the groups. The gastric motility was analyzed before and after acupuncture. Additionally, the correlative analysis was conducted between the gastric motility and ReHo changes before and after acupuncture.
RESULTS(1) After acupuncture, EGG amplitudes in the subjects of each group were lower remarkably as compared with those before acupuncture (all <0.01). The EGG frequencies were not different significantly as compared with those before acupuncture (all >0.05). The EGG amplitudes in the Weishu group and the Zhongwan group were higher than those in the combined-point group (both <0.05). (2) As compared with the conditions before acupuncture, acupuncture at the combined front- and the back- points as well as Weishu (BL 21) and Zhongwan (CV 12) separately all induced the changes in the brain ReHo. Acupuncture at the combined front- and the back- points significantly increased Reho values in the right inferior temporal gyrus, the left thalamus, the precuneus and the posterior cingulate gyrus (all <0.05) and remarkably reduced the ReHo values in the the middle temporal gyrus of the right temporal pole, sulcus calcarinus and precuneus (all <0.05). Compared with the single point groups, acupuncture at the combined front- and the back- points induced the increase of ReHo value in the posterior cingulate gyrus and the decrease of ReHo in the temporal pole (all <0.05). (3) The correlative analysis showed that the changes in the ReHo values in the posterior cingulate gyrus, the thalamus and the precuneus were positively correlated to the changes of the gastric motility amplitudes. The changes in the ReHo values in the temporal pole was negatively correlated to the changes of the gastric motility amplitudes.
CONCLUSIONAcupuncture at the combined back- and front- points of the stomach, as well as acupuncture at single Weishu (BL 21) and Zhongwan (CV 12) induce the ReHo changes in the different brain regions. Acupuncture at the combined back- and front- points of the stomach may induce the ReHo changes in some new brain regions as compared with the acupuncture at the single point. The thalamus, the posterior cingulate gyrus and the precuneus may be the the important integrated brain regions for acupuncture at the back- and the front- points in regulating the gastric motility. The effects of acupuncture at the back- and the front- points for the regulation of the gastric motility are closely related to the thalamus, the limbic system and the default network of the brain regions.
