Objective To investigate the protective effects of mild hypothermia on cells in the CA_1 region of the hippocampus in gerbils following global ischemia-reperfusion injury(IRI),and to explore their mechanism. Methods IRI models were established in 75 gerbils.Any changes in TUNEL positive cells and the expression of Bax and Cytochrome C were then observed in normothermic(N) ,hypothermic(H)and sham(S) groups through immu- nohistochemistry methods.Results In the H group(as compared with the N group)apoptotic cells in the CA_1 sub- field of the hippocampus significantly decreased.The expression of Bax and Cyt C at 3 h,6 h and 1 d were de- creased,and the expression fastigium was delayed.Conclusion Mild hypothermia can moderate and delay cell ap- optosis,and its mechanism might be related with reducing and delaying the expression of Bax and Cyt C released by mitochondria.

Objective To assess the relationship between the Chlamydia pneumonia(CPn)infection and coronary heart disease(CHD).Methods Blood samples from 200 CHD patients and 100 heathy controls were col-lected,and Cpn IgM and Cpn IgG were tested by ELISA.Results The Cpn IgM were found in 113 cases (56.5%) and in 24 controls(24.0%).The Cpn IgG positive cases were in 145(72.5%) patients and in 43 controls (43.0%).The positive rate of Cpn IgM and Cpn IgG in CHD group Was higher than that in control group(P<0.05).Conclusion:CPn positive rate is higher in CHD group than that in control group.Cpn is closely related to the pathogenesis of CHD.

Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) has become the standard first-line treatment for advanced non-small cell lung cancer (NSCLC) patients with EGFR-sensitive mutations. However, acquired resistance cannot be avoided during the targeted treatment of EGFR-TKI, which may lead to the progression of NSCLC. Among them, approximately 50% of patients present with primary lung lesions and/or initial metastastic lesion progression. As a major local treatment, radiation therapy plays an irreplaceable role in the management of patients with advanced cancer. Stereotactic body radiation therapy (SBRT), which is implemented with the Cyberknife, is the most advanced radiation therapy technology to better meet clinical needs. In recent years, based on the abovementioned patterns of tumor recurrence, the treatment mode of pulmonary-lesion SBRT combined with EGFR-TKI can improve the tumor-free survival in advanced NSCLC patients, which has attracted widespread attention. In this article, the clinical research progresses on this combined therapeutic strategy were reviewed.

Objective To determine clinical characteristics and the effects of drug-eluting stents on the occurrence of major adverse cardiac events during percuteneous coronary artery interventional(PCI)and long- term outcomes in patients with chronic renal insufficiency(CRI).Methods Nine hundreds and seventy three patients with angiographically-documented coronary artery disease(lumen inner diameter narrowing>50%), included 516 patients complicated with experienced renal impairment(CRI group)and 457 with normal renal function(control group).Baseline clinical data and coronary angiographic features were recorded.Results Comparing with control group,patients in CRI group were older with higher incidence of hypertension or diabetes and simultaneously complicated by reduced left ventricular ejection fraction,and more complex coronary lesions(type C).During follow-up(mean 17 months),the mortality was significantly higher in CRI than in control group(6.2% vs 3.3%,P<0.05),but the former with CRI was significantly lower by using drug-eluting stents in comparing with bare-metal stents(4.1% vs 8.5%,P<0.05).Conclusion Patients with CRI often complicated with severe coronary artery disease,the mortality after PCI would be significantly reduced by using drug-eluting stents.

The prescriptions containing pericarpium citri reticulatae that built by Professor. Yan were collected to build a database based on traditional Chinese medicine (TCM) inheritance assist system. After analyzed by data mining, such as apriori algorithm, the frequency of single medicine, the frequency of drug combination, the association rules between drugs and core drug combinations can be get from the database. Through the analysis of 1 027 prescriptions with pericarpium citri reticulatae, these prescriptions were commonly used to treat stomach aches, cough and other syndromes. The most frequency drug combinations were "Citri Reticulatae Pericarpium-Poria", "Paeoniae Radix Rubra-Citri Reticulatae Pericarpium" and so on. The drug association rules that the confidence was 1 were "Glycyrrhizae Radix ex Rhizoma --> Citri Reticulatae Pericarpium", "Paeoniae Alba Radix-Cyperi Rhizoma --> Citri Reticulatae Pericarpium", "Poria --> Citri Reticulatae Pericarpium", and so on. The drugs in the prescriptions containing pericarpium citri reticulatae that built by Professor Yan mostly had the effects of regulating the flow of Qi and invigorate blood circulation, which reflected the clearly thought when making prescriptions.

Purpose To assess left ventricular diastolic function in the patients with essentialhypertension. Methods 25 normotensives,93 hypertensiives without hypertrophy (NLVH) and 47 withhypertrophy (LVH)(LVMI, left ventricular mass index > 124 g/m2 in males and 110 g/m2 in females)underwent 2DE and Doppler echocardiography. Results The ratio of early to late peak velocity (E/A)was 1.21 ± 0.24 in normotensives and 1.03 ± 0.23 in NLVH patients( P < 0.01 ); reversed pulmonaryvenous flow at atrial systole PA wave was (32.7 ± 7.5 ) vs (38.9 ± 8.7) cm/s (P < 0.01 ) in normotensivesand in NLVH patients respectively. The isovolumic relaxation time (IVRT) and left atrial dimension (LAD)have significant differences in three groups ( P < 0. 05 - 0. 001 ). EF value was similar betweennormotensives and NLVH patients, but it was lower in LVH patients ( P < 0.01 ). Conclusions E/Aratio, PA wawe, Pai, IVRT and LAD are sensitive parameters indicating mild diastolic left ventriculardysfunction. Systolic left ventricular function has no change in NLVH patients.

OBJECTIVETo study the effects of modified Mahuang Fuzi Xixin Decoction extract (MFXDE) on ischemia/reperfusion induced atrioventricular (A-V) block in rabbits model.
METHODSNew Zealand rabbits were randomly divided into six groups, three test groups (Group TA, TB, TC) and three control groups (Group CA, CB, CC), 10 in each. MFXDE 2 mL/kg was given twice a day by gastrogavage to the test groups, while to the control groups, equal volume of normal saline was given instead, for 3 successive days. Twenty minutes after the last gastrogavage, right coronary artery ligation was performed in rabbits under anesthesia with 1.2 g/kg of 20% urethane via ear marginal vein injection, and lasted for 15 min (Group TA and CA), 60 min (Group TB and CB), and 120 min (Group TC and CC), respectively. ECG lead-II and His Bundle ECG were recorded at different time points to observe P-R interval and A-H interval.
RESULTSP-R interval and A-H interval in the test groups were shorter than in the control groups significantly (all P < 0.05) at the time point of 5 min after ischemia; and at the reperfusion stage, a re-extending phenomenon of P-R and A-H could be found in the CC group after 60 min reperfusion (P < 0.05), but it didn't occure in all the other test groups.
CONCLUSIONMFXDE could improve the ischemia/reperfusion induced A-V conductive function.
