OBJECTIVETo explore effects of Tongxinluo Capsule (TC) on platelet activating factor (PAF), vascular endothelial function, thrombolysis in myocardial infarction (TIMI) blood flow, and heart function in acute myocardial infarction (AMI) patients after delayed percutaneous coronary intervention (PCI).
METHODSTotally 80 AMI inpatients were recruited at Department of Cardiology, People's Hospital of Jiangxi Province, from Jan. 2008 to Sep.2013. Those in line with inclusion criteria were randomly assigned to TC treatment group and the conventional treatment group by random digit table, 40 in each group. Besides, another 40 healthy subjects from examinees at Outpatient Department were recruited as a healthy control group. PCI was performed after 1-week treatment. Then blood samples were collected, and then blood contents of CD62P, CD63, GP II b/III a, ET-1, NO, and plasma von Willebrand factor (vWF) levels were detected. Coronary TIMI blood flow and corrected TIMI frame count (CTFC) were determined during PCI. Meanwhile, noninvasive blood pressure (BP) and heart rate (HR) were recorded before and after PCI, and cardiac function measured. They were compared with the healty control group.
RESULTSCompared with the healthy control group, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 significantly increased, but NO significantly decreased in AMI patients (all P < 0.05). After 1-week intervention of TC, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, NO, and ET-1 significantly decreased (P < 0.05, P < 0.01). Compared with the conventional treatment group at the same time point, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 decreased more significantly in the TC group (P < 0.05, P < 0.01), increased NO levels were also more obviously seen (P < 0.01). The aforesaid parameters changed more obviously at day 30, as compared with those changes at week 1 (P < 0.05, P < 0.01). The TIMI blood flow grade and CTFC were more obviously improved after PCI in the two treatment groups. Better TIMI blood flow was seen in the TC group. TIMI level 3 blood flow rate was higher in the TC group than in the conventional treatment group with statistical difference (P < 0.05). The left ventricular ejective factor (LVEF) after PCI was obviously elevated in the TC group and the conventional treatment group (P < 0.01), and the improvement was more obviously seen in the TC group (P < 0.05). There were 6 cases of recurrent angina, 3 cases of ventricular tachycardial (VT)/ventricular fibrillation (VF), 6 cases of heart failure (HF), 1 case of cardiac sudden death in the conventional treatment group, with the total incidence of cardiovascular events being 40% (16/40). There were 2 cases of recurrent angina, 2 cases of VT/VF, 2 cases of HF, no cardiac sudden death in the TC treatment group, with the total incidence of cardiovascular events being 15% (6/40). There was statistical difference in the recurrent rate of cardiovascular events between the two groups (χ² = 2.27, P < 0.05).
CONCLUSIONTC not only could prevent coronary embolism of AMI patients after delayed PCI, attenuate vascular endothelial injury, but also could improve TIMI blood flow, and strengthen cardiac systolic function.

Objective To investigate the clinical characteristics, operation time and methods for patients with central brain herniation caused by bifrontal contusions. Methods A retrospective study was performed on the medical records of patients with central brain herniation caused by bifrontal contusions admitted from January 2000 to December 2006. There were 45 males and 18 females, at age range of 20-72 years (average 43 years). The majority of the patients were victims of falls and traffic accidents. There were 29 patients treated with immediate operation and 34 with emergency operation. All the operations involved simultaneous bilateral craniectomy for decompression, including 17 patients treated with bilateral decompressive craniectomy and 46 with unilateral decompressive craniectomy. Results The prognosis was favorable in 19 patients with GOS score of 5 or 4 points, severely disabled in seven with GOS score of 3 points, vegetative in four with GOS score of 4 points and the worst in seven with GOS score of 1 point. Of all, 19 patients suffered severe mental disorders especially personality change and disturbance of intelligence. Seven patients were complicated by epilepsy and three by hydrocephalus. Conclusions Based on early clinical manifestations of central brain herniation combined with imaging manifestations, bilateral balance decompression craniectomy can reduce the mortality and morbidity and improve the cure rate of patients with central herniation caused by bifrontal brain contusions.

OBJECTIVETo study the effect of Shumai Capsule (SMC) on angiogenesis and expression of relevant growth factor in rats with myocardial ischemia (MI).
METHODSModel rats of MI were duplicated and treated with SMC (SMC group), bFGF + calparine (positive control group) and normal saline (model group) respectively. Besides, a sham-operative group was set up and treated with normal saline. The rats were sacrificed in batches at the time after being medicated for 1, 2 and 4 weeks, for determining von Willebrand factor (vWF) and vascular endothelial growth factor (VEGF) protein expression in ischemic myocardium by immuno-histochemical staining, myocardial micro-vessel density (MVD) using digital analysis system, and the gene expression of VEGF by quantitative real-time PCR.
RESULTSCompared with the sham-operative group and the model group, levels of MVD, protein and gene expression of VEGF in the SMC group were higher respectively at three time segments (all P <0.01), but showed insignificant difference to those in the positive control group.
CONCLUSIONSMC could promote angiogenesis in ischemic myocardium of rats, the up-regulation on VEGF mRNA and protein expression might be one of the potential mechanisms of SMC in promoting angiogenesis.

OBJECTIVETo observe the effect of the costimulatory molecules CD137 and CD28 on Bcl-2 expression in T cells of mice with D-galactose-induced aging and natural aging.
METHODSSeven-week-old male BALB/c mice were injected daily with D-galactose (120 mg/kg) for 5 months to induce subacute aging, and 16-month-old male BALB/c mice served as the natural aging group. The spleen T cells of were isolated from the rats and stimulated in vitro with conA+IgG, conA+CD137 mAb or conA+CD28 mAb for 48 h. Bcl-2 expression of T cells was detected by flow cytometry and semi-quantitative RT-PCR.
RESULTSIn the subacute aging group, Bcl-2 protein expression rate in the T cells stimulated with conA+IgG, conA+CD137 mAb and conA+CD28 mAb were (24.4-/+1.5)%, (34.4-/+2.4) %, and (45.1-/+2.7) %, which were (19.6-/+2.0) %, (26.3-/+1.9) %, and (48.5-/+2.2) % in the natural aging group, respectively. In vitro stimulation with conA+IgG, conA+CD137 mAb and conA+CD28 mAb resulted in expression rate of bcl-2 mRNA in the T cells of 0.309-/+0.039, 0.547-/+0.036, and 0.780-/+0.041 in the subacute aging group, and 0.283-/+0.038, 0.535-/+0.041, and 0.771-/+0.063 in the natural aging group, respectively.
CONCLUSIONCD137 and CD28 can promote bcl-2 expression at both mRNA and protein level in T cells in aging mice, which may be one of the mechanisms through which CD137 and CD28 molecules inhibit aging T cell apoptosis and maintain their function.

OBJECTIVETo study the metastasis-associated molecules differentially expressed in highly and poorly metastatic sublines and the mechanism of metastasis in lung giant cell carcinoma.
METHODSHighly and poorly metastatic sublines (PLA801D and PLA801C)were used as metastasis model. Cell motility and invasion assay in vitro were first compared between the two sublines. Then, gelatin zymography analysis was used to determine the MMP-2 and MMP-9 activity. The protein expression level of secreted MMP-2, MMP-9, TIMP-1, TIMP-2 and intracellular expression level of p53, p16, PCNA, CD44(V6) isomeride, E-cadherin, CK18, nm23-H1 as well as the mRNA expression level of MMP-2, MMP-9, TIMP-1, TIMP-2, VEGF were compared through Western blot. Semi-quantitative RT-PCR analysis was used to determine the intracellular mRNA expression of MMP-2, MMP-9, TIMP-1, TIMP-2 and VEGF.
RESULTSThe in vitro cell invasion potential of highly metastatic subline PLA801D was significantly higher than that of poorly metastatic subline PLA801C by about 4 folds, while the cell motility potential was similar. The secreted MMP-2 activity was notably higher in PLA801D, which was initiated by the higher expression of MMP-2 at protein and mRNA level. In addition, the expression level of p53, PCNA, CK18 protein and VEGF mRNA were significantly higher, while the expression level of p16, E-cadherin and nm23-H1 protein were significantly lower in PLA801D. Some molecules such as MMP-9, TIMP-1, TIMP-2, CD44(V6) isomeride, which had been reported to be associated with tumor metastasis, were not observed to change significantly between the two sublines.
CONCLUSIONThere are significant differences in metastatic potential and phenotypes between highly and poorly metastatic sublines of lung giant cell carcinoma. Some differentially expressed molecules might be playing roles in promoting or inhibiting metastasis of lung giant cell carcinoma, which may be useful to elucidate the mechanism of metastasis.
