Objective:To investigate the clinical value of neck vascular ultrasound and homocysteine (Hcy) level in patients with cerebral infarction and carotid stenosis.
Methods: Our research included 2 groups. Cerebral infarction group, n=115 patient who were treated in our hospital from 2012-01 to 2013-12, and Control group, n=110 healthy subjects from physical check-up. Neck vascular ultrasound was conducted to classify the degree of carotid stenosis as ①no stenosis, ②mild degree, the stenosis rate≤29%, ③moderate degree, the stenosis rate at 30%~69%,③severe degree, the stenosis rate at 70%~99%,④complete occlusion. Carotid plaque formation and vascular intima-media thickness (IMT) were examined by neck ultrasound. Blood levels of Hcy and triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) were
measured in clinical laboratory.
Results: Compared with Control group, Cerebral infarction group had the higher rate of carotid stenosis 89.56%vs 10.91%, more plaque formation 73.91%vs 6.08%and increased IMT (1.85 ± 0.42) mm vs (0.75 ± 0.21) mm;higher blood levels of Hcy (42.32 ± 12.02) μmol/L vs (6.32 ± 2.45) μmol/L and higher rate of high blood Hcy syndrome 71.30%vs 3.63%;higher levels of TC (4.25 ± 1.12) mmol/L vs (1.63 ± 0.74) mmol/L and LDL-C (5.96 ± 1.36) mmol/L vs (2.32 ± 0.82) mmol/L, P<0.05. In Cerebral infarction group, the patients with complete carotid occlusion and severe stenosis had the higher rate of plaque formation and increased IMT;higher levels of Hcy and more high blood Hcy syndrome;higher levels of TG and LDL-C than the patients with mild and moderate carotid stenosis, P<0.05. Logistic analysis indicated that the levels of IMT, Hcy and LDL-C were the independent risk factors for cerebral infarction and carotid stenosis.
Conclusion: The patients with cerebral infarction and carotid stenosis have obviously increased blood level of Hcy. Hcy may predict various degree of carotid stenosis in relevant patients.

Objective To observe the change of brain iron content in deep gray nucleus using susceptibility weighted imaging (SWI) in patients with Parkinson's diseases (PD). Methods The SWI examination was performed in 40 PD patients (10 patients with Hoehn-Yahr stage Ⅰ , 9 patients with Hoehn-Yahr stage Ⅱ , 9 patients with Hoehn Yahr stage Ⅲ , 6 patients with Hoehn-Yahr stage Ⅳ, 6 ptients with Hoehn Yahr stage Ⅴ ) and 33 gender- and age- matched controls, after conventional brain magnetic resonance imaging examination on a 3.0T magnetic resonance imaging.The signal values of substantia nigra zona compacta (SNc), substantia nigra zona reticulate (SNr),red nucleus (RN), putamen (Pu), globus pallidus (GP) and caudate nucleus (CN) were assessed.Results Compared with the controls, the PD patients had statistically significance of signal value differences of SNc (P=0.002), SNr (P=0.043). RN (P= 0.003), Pu (P=0.023). GP (P=0.001) andCN (P=0.033). The more significant differences of SNc(P=0.001), SNr (P=0.010),RN (P＜0. 001 ), Pu (P=0. 008), GP (P＜0. 001) and CN (P=0. 011) were observed between more severe PD lesion and control. The signal values of SNc and GP showed obviously negative correlations with Hoehn-Yahr grading (SNcr=-0.943. P＜0.001; GPr=-0.923, P＜0.001). But there was weakly correlation of the signal values of SNr, RN, Pu, CN with Hoehn Yahr grading (SNr r=0. 496. P=0.001; RN r=-0. 480. P=0.002; Pu r=-0. 494, P=0.001; CN r=-0.471, P=0.002) Conclusions Measurement of the brain iron content of SNc and GP using SWI on MRI is a reliable means of diagnosing PD, and it has significant correlation with Hoehn-Yahr grading, It could evaluate the severity of PD.

Objective To investigate the relationship between growth inhibiting effect of arsenic trioxide(As_2O_3) and phosphorylation of P27kip threonine residue 187(P27T187) in human hepatocellular carcinoma(HCC) cell line SMMC-7721.Methods SMMC-7721 were treated for 72 h with 2 ?mol/L As_2O_3.The cell growth inhibition was detected by cell counting and the cell cycle was detected by flow cytometry(FCM).The expression and localization of P27,T187 phosphorylated P27(p-P27T187) were detected by Subcellular Fractionation,Western blot and immunoflurescence.Results As_2O_3 significantly inhibited the proliferation of SMMC-7721 cell and cell cycle was arrested in G2/M.A significant decrease in p-P27T187 expression and a reciprocal increase in P27 expression were found in 2 ?mol/L As_2O_3-treated SMMC-7721 cell.Meanwhile,As_2O_3 decreased the protein levels of Cdk2 and cyclinE.The location of P27 was transferred from cytoplasm to nuclei and the expression of p-P27T187 was decreased in nuclei.Conclusion As_2O_3 inhibits the phosphorylation of P27T187,thereby promoting P27 accumu-lation in SMMC-7721 cell nuclei,inducing cel1 cycle arrest and growth inhibition.

Objective To investigate the expression of C-JUN activation domain binding protein 1(JAB1)and its relationship with expression of P27 protein in human hepatocellular carcinoma(HCC),and to determine whether JAB1 is associated with clinicopathological parameters and prognosis of HCC.Methods Immunohistochemical analysis was performed to investigate the expression of JAB1 and P27 in 76 cases of HCC and adjacent nontumorous tissues.Fresh tumor tissues and their adjacent nontumorous tissues from 8 cases of HCC were collected for Western blot and immunoprecipitation assays.Results The expression of JAB1 in HCC was significantly higher than that in adjacent nontumorous tissues.In contrast,P27 level was higher in nontumorous liver tissues than that in HCC.JAB1 overexpression was correlated with histological differentiation,serum alpha-fetoprotein(AFP)level and metastasis(P

Objective To study the resuscitative effect of hypertonic electrolyte glucose solution (HEGS) on the haemodynamics pa-rameters in enteral resuscitation of burn shock. Methods Eighteen beagle dogs with 35% TBSA third degree burned were used in this stud-y. They were random divided into no-resuscitation group (NR group), enteral resuscitation with HEGS group (EH group) and intravenous resuscitation with isotonic electrolyte glucose solution (lEGS) group (Ⅱ group). The fluid resuscitation was given from half an hour after TBSA). The haemodynamics parameters (cardiac index, mean arterial pressure, intrathoracic blood volume index, and systemic vascular re-sistance index) were continuously assessed by PICCO. Result The cardiac output index reduced markedly after bum in the three groups, and then returned after 2h in two resuscitation groups, which were higher than that in the NR group( P<0.05). The mean arterial pressure reduced in the three groups, which was higher in the two resuscitation groups than that in NR group(P < 0.05). The intrathoracic blood volume index was rapidly reduced in the three groups. It returned in EH group from 2 hours after burned, which was still higher than that in the other two groups (P < 0.05). Meanwhile the systemic vascular resistance index was increased quickly. It was reduced in EH group from 2 hours after burned, which was lower than that in the other two groups (P < 0.05). Conclusion The results show that it was feasible for 35% TBSAⅢ° burn-injury dogs to be resuscitated with 1.8% hypertonic electrolyte-glucose solution by enteral, which can markedly reduce liquid quantity needed.

Objective Cisplatin(DDP)is widely used in the chemotherapy of lung cancer. However, cisplatin resistance represents a major obstacle in its effective treatment. Our preliminary work has demonstrated that inactivated Sendai virus(HVJ-E)shows that it induces apoptosis in murine melanoma cells(B16)and obviously inhibites the tumor growth in tumor-bearing BALB/c nude mice. This study aims to investigate whether inactivated HVJ-E has an effect of inducing apoptosis in cisplatin-resistant A549/DDP lung adenocarcinoma cells in vitro and in vivo. Methods HVJ-E and A549/DDP cells were co-cultured in vitro,and the effect of HVJ-E on the apoptosis in A549/DDP cells was detected by flow cytometry. In addition,HVJ-E was injected into the tumor in vivo, and its oncolytic effect was observed by TUNEL assay of tissue sections and measurement of tumor size. Results After co-cultured with HVJ-E for 12 h,24 h and 36 h, the apoptosis rate of A549/DDP cells in late stage detected by flow cytometry was 7.7%, 12.6% and 18.9%,respectively,showing a significant difference between 12 h and 24 h, and between 24 h and 36 h. TUNEL assay showed that there was more apoptosis in tumor cells in vivo in the experimental group than in the control group. Meanwhile, intratumoral injection of HVJ-E induced a significantly smaller tumor volume in the experimental group compared with the control group(P ﹤ 0.05). Conclusions Our findings indicate that inactivated HVJ-E can induce apoptosis in A549/DDP cells both in vitro and in vivo, and intratumoral injection of inactivated Sendai virus significantly reduces the tumor growth in vivo.
