OBJECTIVETo investigate the effect of Tianma Gouteng recipe (TGR) on interfering left ventricular (LV) and aortic hypertrophy and tissue angiotensin II (Ang II) in rats with renovascular hypertension.

METHODThe animal model of renovascular hypertension was used in this experiment. Hypertensive rats were randomly allocated into model group, Enalapril group and TGR group, and the drugs were used for 6 weeks continuously. During this period, the blood pressure of rats was measured every two weeks. After rats were sacrificed, the wet weight, tissue Ang II level of LV and aorta, and the cardiac index were measured.

RESULTOne week after renovascular stenosis, the systolic blood pressure (SPS) of model group was increased by 37.4 mmHg, and 7 weeks after stenosis, the LV and aortic hypertrophy was obvious increased, meanwhile, tissue Ang II of LV and aorta was raised markedly (P < 0.01). Contrasting with the model group, blood pressure was reduced and the morphological index was improved in Enalapril group respectively (P < 0.05 or P < 0.01); the wet weight of LV and aorta were reduced, the morphological index was improved, the rise of Ang II in tissue was suppressed, in TGR group significantly.

CONCLUSIONTGR can attenuate myocardial and aorta hypertrophy induced by renovascular hypertension, and suppress the rise of Ang II in tissue significantly. This suggests that TGR has the effects on interfering LV and aortic hypertrophy by an independent-antihypertensive way.

OBJECTIVETo investigate the effects of Tianzhi Keli (TZ) on acetylcholine (ACh) and catecholamine levels in striatum of rats with neuromitochondrial impairment, and try to find out the neuroprotective mechanism of TZ.

METHODThe microdialysis and high performance liquid chromatography (HPLC)-post column Immobilized enzyme reactor (IMER)-electrochemical detection (ED) were used to establish a model of mitochondrial energy metabolism impairment which induced by perfusion with sodium azide (NaN3), and measure continuously the effects of TZ on extracellular ACh, choline (Ch) and catecholamine of model rats.

RESULTAfter perfusion with NaN3, ACh, noradrenalin (NE), adrenaline (E), dopamine (DA), 3,4-Dihydroxyphenyl-aletic (DOPAC), and homovanillic acid (HVA) levels were decreased obviously (P < 0.05-0.01), while Ch level was increased distinctly (P < 0.01). Transmitters levels were recovered individually after stop the perfusion with NaN3. TZ can postpone the decrease of ACh and advance the recover of Ch. The effect of TZ coupled with duxil on increasing ACh level is more obviously than effect of TZ or duxil. TZ is also showing a tendency to postpone the decrease of catecholamine and advance its recovery. TZ coupled with duxil can advance the recovery of DOPAC and adjust the metabolic abnormity positively.

CONCLUSIONTZ has effect on protecting impairment of choline neurosystem, which induced by damage of mitochondrion and abnormity of energy metabolism; coupled with duxil have synergistic action. TZ also has tendency to protect the impairment of epinephrine and dopamine neurosystem.

OBJECTIVETo explore the prognostic impact of bone marrow involvement (BMI) and therapy in diffuse large B cell lymphoma (DLBCL).

METHODSThe clinical characteristics and prognosis of 83 DLBCL patients with or without BMI were retrospectively analyzed. The treatment outcome of standard CHOP regimen (CHOP group), intensive-dose regimen (intensive-dose group) and rituximab combined therapy (rituximab group) were compared.

RESULTSThe adverse prognostic factors including LDH elevation, ECOG score > or =2, higher IPI and aaIPI score, B symptom, hepatomegaly, splenomegaly, hemoglobin <110 g/L, platelet <100 x 10(9)/L and serum albumin <35 g/L were more prevalent in DLBCL patients with BMI than in those without BMI. Multivariate analysis showed that BMI was an independent prognostic factor of DLBCL. The 3-year OS and PFS rates in rituximab group were 78.1% and 64.3%, respectively, being statistically higher than that in CHOP group (23.6% and 21.8% respectively, P = 0.000 for both) and in intensive-dose group (33.3% and 25.7% respectively, P = 0.002 and 0.001, respectively). But no difference between the latter two groups (P = 0.411 and 0.694, respectively). For the patients with BMI, the 3-years OS and PFS in rituximab group (57.1% and 57.1%) were statistically higher than that in CHOP group (13.9% and 14.1%) and intensive-dose group (29.5% and 16.8%) (P = 0.029 and 0.012 respectively), respectively and also no difference in the latter two groups (P = 0.226 and 0.376 respectively). In the rituximab group, the 3-years OS and PFS were 86.7% and 67.3% respectively in patients without BMI, being higher than that in patients with BMI (57.1% and 57.1%), but the difference was not statistically significant (P = 0.645 and 0.965 respectively).

CONCLUSIONBMI is a negative independent prognostic factors of DLBCL patients. The rituximab combined chemotherapy can significantly improve the therapeutic effect of the DLBCL, and relieve the negative impact of BMI.

To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell surface were isolated. The cytotoxicity of TRAIL to selected cells was higher than that of TRAIL to HepG2 cells by MTT method (P < 0.01). The result suggested that the cloned hDR5 gene had biological activity. MTT assay showed that, rClone30- hDR5 in combination with TRAIL more efficiently inhibited the tumor growth of HepG2 cells compared to rClone30-hDR5 or TRAIL in vitro. The results of Annexin V-FITC/PI staining and Quantitative Real-time PCR indicated that rClone30-hDR5 in combination with TRAIL significantly increased the mRNA levels of caspase 3 and caspase 8, and induced the apoptosis of tumor cells. HepG2 cells were infected with rClone30-hDR5 or rClone30 at MOI of 1. The expression of hDR5 on tumor surface increased significantly by rClone30-hDR5 compared to that by rClone30, which contributed to the sensitivity to TRAIL. In conclusion, rClone30-hDR5 in combination with TRAIL has potential application value in cancer treatment.

OBJECTIVETo evaluate quality of surveillance and emendate rates of birth and death of population of the Three Gorges area.

METHODSData on the two samples collected were designed based on principle of capture-recapture method. An investigation of missing report of birth and death was conducted in 7061 families selected through stratified random sampling method. We collected and registered the data of birth and death in every family investigated and checked with correlative records reported in disease surveillance system of the Three Gorges area. The missing report rates and the 95% confidence intervals of birth rate and death rate were calculated.

RESULTSThe underreporting rates of birth and death were 13.91% and 15.60% and death of infant was 33.33%. The emended birth rate was 8.92 per thousandth and the 95% confidence interval of birth rate was 8.38 per thousandth-9.45 per thousandth. The emended report rate of death was 6.88 per thousandth and the collectivity 95% confidence interval was 6.37%-7.38 per thousandth.

CONCLUSIONResults showed that the quality of birth and death in the disease surveillance reporting system of Three Gorges area was competent to the quality level of the standard set for national disease surveillance system. The birth and death rates of population in the Three Gorges area were under 10.00 per thousandth.

OBJECTIVETo observe the effects of Tianma Gouteng Fang (TGF) on the transmitter amino acids in the hippocampus extracellular liquids in freely moving rats subjected to incomplete brain ischemia.

METHODHippocampus extracellular liquids was collected continuously by the microdialysis sampling technology in freely moving rats during pre-ischemia, incomplete ischemia and reperfusion periods induced by the occlusion and loose of both common carotid arteries. Each dialysate sample was assayed for GABA, Tau, Glu, Cys and Arg with HPLC-electrochemical detector.

RESULTTGF increased the concentrations of GABA and Tau in the extracellular liquids of rat hippocampus. Compared with the model group, the concentration of Glu in the middle and large dosage groups of TGF, during the 120 min of ischemia, reduced by 38.64% and 31.35%, Tau increased by 13.99% and 12.86%, GABA advanced 25.89% and 33.99%, Cys decreased by 40.93% and 42.08%, Arg raised to 116.95% and 108.96%, respectively. After 120 min of reperfusion, the concentration of Glu decreased by 14.55% and 11.48%, Tau increased by 16.13% and 14.03%, GABA increased by 24.41% and 26.22%, respectively.

CONCLUSIONTGF can increase the concentration of inhibitory amino acids in hippocampus extracellular liquids of rats and inhibit the excessive release of excitatory amino acids and raise the concentration of the inhibitory amino acids and Arg during the ischemia-reperfusion periods. Therefore, TGF can play the neuroprotective role.
