Objective To investigate the level about illness perception in patients with coronary heart disease. Methods From July to De-cember, 2015, 198 inpatients with coronary heart disease who were admitted into hospitals twice or more were enrolled. They were assessed with Illness Perception Questionnaire-Revised (IPQ-R). Results The score of common symptoms was (4.55±1.64). The symptoms, for exam-ple, chest pains, uncomfortable feeling in chest, cold sweat, flustered and breathlessness were most frequently experienced and most often identified. For the illness perception part, the scores on subscales of treatment control and consequences were higher than 3, which was the neutral point. For the cause dimension part, the highest scores was (3.38 ± 0.90) in diet or eating habits, followed by (3.38 ± 0.89) in aging. Among these factors, immune factors had the highest mean score, followed by stress factor. Conclusion The level of illness perception in pa-tients with coronary heart disease was in the middle level, and individual differences were obvious. The awareness of the disease and the in-tervention of the patient should be strengthened.

Objective To investigate the effect of propofol on the learning and memory function in neonatal rats under hypoxic conditions. Methods Eighty-four 7-day-old SD rats were randomly divided into 6 groups (n = 14 each): propofol + 18% oxygen (propofol-hypoxia, group PH), propofol + air (group PA), propofol +100% oxygen (propofol-oxygen, group PO), 0.9% normal saline (NS) + 18% oxygen (group CH), NS + air (group CA), NS + 100% oxygen (group CO). The rats received injection of intraperitoneal propofol 50 mg/kg or NS 5.0 ml/kg once a day for 7 consecutive days and they were exposed to 18% oxygen, air or 100% oxygen at the end of each injection. SaO2 and respiratory rate (RR) were monitored and recorded after administration. The rats were returned to the cage after recovery of the righting reflex. Six rats in each group were sacrificed 24 h after the 7th injection, and the brain tissues were taken to observe the apoptosis in hippocampal neurons. Morris water maze test was used to test the learning and memory function 2 weeks after administration in the other rats. Results RR was significantly lower and the escape latency at T1.2 longer in group PO than in group CO (P < 0.05). RR and SaO2 were significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crossing the original platform was reduced in group PA compared with group CA, and in group PH compared with group CH (P < 0.05). Compared with group PO, SaO2 was significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crosing the original platform was reduced in group PA (P < 0.05). Conclusion Propofol induces apoptosis in hippocampal neurons and decreases the learning and memory function in neonatal rats under hypoxic conditions.

Objective To investigate the biological effects of 125I seeds and 60Co γ-rays on the non-small cell lung cancer cells A549 and the normal bronchial epithelium cells BEAS-2B.Methods A549 and BEAS-2B cells were irradiated with 125I seeds and 60Co γ-rays.The survival fraction was detected by colony formation assay.The cell cycle and cell apoptotic ratio were detected by flow cytometry.The expression of cell apoptotic related proteins was examined by western blot.Results After irradiation with different doses,the survival of A549 cells irradiated with 125I seeds was lower than that irradiated with γ-rays (t =6.06,9.42,4.90,P <0.05).After irradiation with 4 Gy of 125I seeds and 60Co γ-rays,the G1 phase percentages of A549 cells were 70.67% ± 1.49% and 59.59% ± 0.71% (t =10.77,P < 0.05),and the apoptotic ratios of A549 cells were 18.09% ±0.73% and 9.81% ±0.16% (t =19.40,P< 0.05),respectively.125I seeds irradiation remarkably up-regulated the expressions of Bax and cleaved Caspase-3 proteins,down-regulated the expression of Bcl-2 proteins compared with 60Co γ-rays irradiation on A549 cells.However,the apoptotic ratio and the expressions of apoptosis-related proteins in BEAS-2B cells had little difference between two types of radiation.Conclusions The anti-proliferative effect of 125I seeds irradiation on A549 cell is more remarkably than that of 60Co γ-rays.The imbalance of Bcl-2/Bax ratio and the eventually activation of Caspase-3 proteins may play an important role in the anti-proliferative effect induced by the continuous low dose radiation of 125I-seeds.

Tertiary lymphoid structure (TLS) is the ectopic lymphoid tissue around the chronic inflammatory site of tumor, infection diseases, autoimmunity diseases, organ transplantation and so on. TLS is regarded as the vital niche of antitumor immune response in tumor microenvironment for abundant immune cells, and is correlated with better clinical outcomes and immunotherapy response in most solid tumors. As a typical inflammation-driven cancer, hepatocellular carcinoma (HCC) is controversial with the influence of TLS on patients prognosis. In this paper, the composition, formation mechanism, recognition and clinical value of TLS in HCC were briefly reviewed.

Objective:To investigate the correlation between triglyceride-glucose (TyG) index and high on-treatment platelet reactivity (HTPR) during clopidogrel treatment in patients with ischemic stroke.Methods:Patients with ischemic stroke who received maintenance dose of clopidogrel (75 mg/d) in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2017 to March 2021 were retrospectively included. The highest quartile (Q4) of the TyG index was defined as insulin resistance. Platelet reactivity was assessed by thromboelastogram and clopidogrel HTPR was defined as the clot strength induced by adenosine diphosphate (MA ADP) >47 mm. Multivariate regression model was used to analyze the independent correlation between TyG index and platelet reactivity. Results:A total of 83 patients were included. The TyG index showed a linear correlation with MA ADP. The patients were divided into 4 groups according to the quartile of TyG index. The incidence of clopidogrel HTPR increased significantly with the increase of the quartile of the TyG index ( Ptrend=0.017). Multivariate analysis showed that there was a significant independent correlation between insulin resistance and clopidogrel HTPR (odds ratio 4.597, 95% confidence interval 1.285-16.446; P=0.019). Conclusions:In patients with ischemic stroke treated with clopidogrel, the incidence of clopidogrel HTPR gradually increases with the increase of the quartile of the TyG index. The insulin resistance assessed by the TyG index is independently associated with clopidogrel HTPR.

OBJECTIVE:
To explore the effect of ROCK inhibitor Y-27632 on the matrix metalloproteinase 2 and 9 (MMP2 and MMP9) gene expression and activity in tumor necrosis factor α (TNF-α)-treated human umbilical vein endothelial cell (HUVEC).
METHODS:
HHUVEC was divided into 3 groups, a control group, a TNF-α group, and a TNF-α plus Y-27632 group. The expressions of vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), MMP2 and MMP9 were examined by real-time PCR. The MMP2/9 activity was measured by gelatin zymography.
RESULTS:
Compared to the control group, the mRNA expressions of ICAM-1, VCAM-1, MMP2 and MMP9 were increased TNF-α-treated cells, which were suppressed by ROCK inhibitor (P<0.01). The MMP2/9 activity was elevated in TNF-α-treated cells, which was reversed by ROCK inhibitor (P<0.05).
CONCLUSION
ROCK inhibitor can suppress TNF-α-induced inflammation in endothelial cells through down-regulation of MMP2/9.
