OBJECTlVE To expIore the intervention effect of Iosartan on the Iung oxidative injury in-duced by paraquat(PQ). METHODS AduIt maIe SD rats were randomIy divided into 4 groups:normaI controI group,PQ intoxication group(rats were treated with singIe ig PQ 40 mg·kg-1 ),Iosartan inter-vention for 7 and 14 d groups(rats were ig given Iosartan 10 mg·kg-1 daiIy for 7 and 14 consecutive days after PQ was given). AII rats were sacrificed on the 16th day to obtain Iung tissues. HE staining was used to observe the Iung pathoIogicaI changes. The activities of superoxide dismutase(SOD),cataIase (CAT)and totaI antioxidant capacity(T-AOC)and content of Iipid peroxide(LPO)were detected by spectrophotometry. ReaI-time quantitative PCR was used to investigate the NF-κB mRNA expression in Iung tissue. RESULTS PathoIogicaI examination showed that acute Iung injury and significant Iung fibro-sis appeared in PQ intoxication group but were reversed by Iosartan. The IeveIs of SOD,CAT and T-AOC decreased whiIe the content of LPO in PQ intoxication group increased significantIy compared with controI group(P﹤0.05). Compared with PQ intoxication group,the IeveIs of SOD,CAT and T-AOC in-creased and the content of LPO decreased in Iosartan intervention for 7 and 14 d groups(P﹤0.05),and the IeveIs of T-AOC and LPO in Iosartan intervention for 7 and 14 d groups and the activities of SOD and CAT in Iosartan intervention for 14 d group nearIy returned to normaI. The mRNA expression of NF-κB was upreguIated after rats were exposed to PQ,downreguIated in Iosartan intervention for 7 and 14 d groups in rat Iung tissues( P﹤0.05),but nearIy returned to normaI. CONCLUSlON Oxidative stress may be invoIved in the acute PQ poisoning process and Iosartan might have intervention effect on acute PQ Iung damage by improving the antioxidant capacity and downreguIating the mRNA expression of NF-κB.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

OBJECTIVECoronary heart disease (CHD) is one of the most common causes of death in the world. Some studies suggested that CHD begins in childhood. Obesity and dyslipidemia are important risk factors of coronary heart disease. Apolipoprotein (apo)E gene associated with dyslipidemia and coronary heart disease. The present study was designed to investigate the expression status of apoE gene in peripheral blood monocyte and association of apoE gene expression with lipids in children with obesity.

METHODSAmong 32 children with obesity and 32 healthy children without obesity or overweight, ApoE gene expressions were determined by competitive reverse transcription-polymerase chain reaction in peripheral blood monocyte. The concentrations of plasma triglyceride, total cholesterol, low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, lipoprotein(a), apoA I, apoB(100) and apoE were measured.

RESULTSExpression of apoE gene was detected in peripheral blood monocyte. Expression of apoE gene was significantly reduced in children with obesity as compared with control group (0.29 +/- 0.14 moles/mole GAPDH mRNA vs. 0.36 +/- 0.10 moles/mole GAPDH mRNA, t = 2.15, P < 0.05). The more severe was the degree of obesity, the more significantly reduced the expression of apoE gene; the degree of obesity was negatively correlated with the levels of expression of apoE gene (correlation coefficient = -0.40, P < 0.05). Compared with control group, the levels of triglyceride, total cholesterol, low density lipoprotein-cholesterol, and apoB(100) were higher, and those of high density lipoprotein-cholesterol, apoA I and apoE were lower in children with obesity [(1.68 +/- 0.50) mmol/L vs. (0.99 +/- 0.54) mmol/L, (4.47 +/- 0.91) mmol/L vs. (3.33 +/- 0.90) mmol/L, (2.23 +/- 0.71) mmol/L vs. (1.13 +/- 0.96) mmol/L, (94.48 +/- 9.97) mg/dl vs. (83.81 +/- 15.64) mg/dl, (1.47 +/- 0.39) mmol/L vs. (1.73 +/- 0.36) mmol/L, (112.71 +/- 27.86) mg/dl vs. (134.80 +/- 45.36) mg/dl, (24.50 +/- 10.92) mg/L vs.(35.07 +/- 9.79) mg/L, respectively, P < 0.05]. ApoE gene expression was associated with plasma lipids metabolism in children with obesity. The quantity of apoE gene expression was inversely associated with low density lipoprotein-cholesterol, positively correlated with apoE (correlation coefficient = -0.33, 0.35, respectively, P < 0.05). The quantity of apoE gene expression was not associated with total cholesterol, triglyceride, high density lipoprotein-cholesterol, lipoprotein(a), apoA I, and apoB(100) (correlation coefficient = -0.19, -0.11, 0.16, 0.09, 0.18, 0.22, P > 0.05).

CONCLUSIONExpression of apoE gene was significantly reduced in peripheral blood monocyte in children with obesity. The quantity of apoE gene expression was associated with degree of obesity and abnormality of blood lipids.

OBJECTIVESecond mitochondria-derived activator of caspase (Smac) is a recently identified, novel pro-apoptotic molecule, which is released from mitochondria into the cytosol during apoptosis. Smac promotes activation of caspases by neutralizing members of the inhibitor of apoptosis proteins (IAPs) family, such as X-linked inhibitor of apoptosis protein (XIAP). The objective of the study was to examine the pro-apoptotic effect of human Smac gene on Burkitt's lymphoma Raji cells.

METHODSThe full length cDNA of human Smac gene was amplified by reverse transcription-PCR from total RNA of HEK-293 cells. The PCR product was ligated with linearized vector pGEM-T-easy supplied in the TA cloning kit and sequenced. The correct cDNA of full length Smac was subcloned into eukaryocytic expression vector pcDNA3.1/myc-his and transfected into human Burkitt's lymphoma cell line Raji by lipofectamine-mediated transfection. The expression of full length Smac was determined by Western blot. Morphological observation was done with the laser scanning confocal microscope by double staining the Raji cells with Hoechest 33,258 and propidium iodide. Flow cytometry was used to evaluate apoptosis. Relative caspase-3 activity was determined by colorimetric assay.

RESULTSRecombinant eukaryocytic expression vector pcDNA3.1/Smac, which contained full length Smac, was successfully constructed. After pcDNA 3.1/Smac was transfected into human Burkitt's lymphoma Raji cell line for 24 hours, Raji cells showed apparent apoptosis with a percentage of (43.7 +/- 2.5)%, which was higher than that of non-transfected group and free vector-transfected group (P < 0.05). Compared with non-transfected group (0.136 +/- 0.036) and free vector-transfected group (0.138 +/- 0.026), the relative caspase-3 activity of Raji cells transfected by pcDNA3.1/Smac (0.936 +/- 0.041) was significantly enhanced (P < 0.05).

CONCLUSIONTransfection and expression of human Smac gene could significantly induce apoptosis of human Burkitt's lymphoma Raji cells. The mechanism is associated with the increase of caspase-3 activity.

Inherited afibrinogenemia is a rare autosomal recessive bleeding disease characterized by complete absence of fibrinogen in blood. To identify the genotype in a Chinese family with inherited afibrinogenemia, the samples of peripheral blood were collected from 6 members of 3 generations. The activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and fibrinogen (Fg, clauss) were tested. Fg was also analyzed by using immunoturbidimetry method. DNAs of six members were extracted by using a DNA extract kit. All the exons and exon-intron boundaries of the three fibrinogen genes were amplified by using PCR and analyzed by direct sequencing. The results showed that the parents of proband were 3 degree consanguinity. A homozygous c.934_935insA in FGA was found in proband which results in the change of protein p.Ser312fsX42. The parents, grandmother, maternal grandmother and father's sister were all detected with heterozygous mutation which was same as that in proband. In conclusion homozygous c.934_935insA in FGA is a cause of inherited afibrinogenemia and a novel mutation being reported.

OBJECTIVETo analyze the clinical and laboratory features of chronic lymphocytic leukemia (CLL).

METHODSRetrospective investigation of 263 patients with CLL in our hospital between Feb. 2000 and Jan. 2007.

RESULTSThe median age was 60 years with male/female ratio of 2.17 : 1. Patients who were asymptomatic at diagnosis (35.4%) had low Rai grades. Fatigue and lymphadenopathy (54.8%) were the most common features at presentation. Infections, connective tissue diseases and secondary tumors frequently occurred in CLL. WBC counts were between (10 - 100) x 10(9)/L, with lymphocytes percentages more than 0.50 in 97.1% patients. Bone marrow was normal- to hyper-cellularity with lymphocytes percentages more than 0.300 in 99.4% patients. Diffuse infiltrations in bone marrow section were found in 72.2% patients. There were lower CD5 (85.1%) and higher CD25 (78.9%) positivities in the present series as compared with that in other reports. Hypogammaglobulinemia, especially hypo-IgM, usually occurred. Chromosome abnormality were rarely found by routine chromosome examination.

CONCLUSIONSThere were some clinical and laboratory characteristics different from that of abroad data. Further exploration of new markers is required for prognosis prediction and treatment choice.
