OBJECTIVETo observe the protective effect of Acanthopanax senticosus saponins (ASS) on myocardial ischemia-reperfusion injury in rats.

METHODThe myocardial ischemia-reperfusion model was induced by 30 min left anterior descending coronary occlusion and 120 min reperfusion in rats. The changes of myocardial infarct size (MIS), the serum creatine phosphokinase (CK) and lactate dehydrogenase (LDH) activity, the serum lipid peroxidation (LPO) content and superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity and plasma endothelin (ET), angiotensin II (Ang II), prostacycline (PGI2) and thromboxane A2 (TXA2) levels and myocardial free fatty acid (FFA) content of infarct and noninfarct area were determined.

RESULTIn rats treated by ASS (in a dosage of 25, 50 and 100 mg x kg(-1) i.v. at 30 min after coronary occulusion), the MIS was significantly reduced, the serum CK and LDH activity, the plasma ET, Ang II and TXA2 level and myocardial FFA content declined, while plasma PGI2 level and PGI2/TXA2 was increased signficantly. In addition, serum LPO content declined, SOD and GSH-Px activity were increased markedly.

CONCLUSIONASS has protective effect on myocardial ischemia-reperfusion injury, which may be due to its function of improving free radicals and myocardial metabolism, decreasing plasma ET, Ang II and TXA2 levels and increasing plasma PGI2 level and PGI2/TXA2 ratio etc.

OBJECTIVETo observe effects of ginsenoside-Rb (G-Rb) on total cholesterol, lipoprotein cholesterol metabolism and anti-oxidation in experimental hyperlipidemia rats.

METHODHyperlipidemia rats were respectively given G-Rb 50, 100, 200 mg x kg(-1) x d(-1) ig for twelve days. Total cholesterol, lipoprotein cholesterol and lipid peroxidation (LPO) contents, prostacycline (PGI2), thromboxane (TXA2), superoxide dismutase (SOD) and blood viscosity were measured. Fat accumulation in liver was also observed.

RESULTTriglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-c) in serum, TXA2 in plasma, LPO in serum and liver, and blood viscosity were decreased significantly. High density lipoprotein cholesterol (HDLc) in serum, PGI2 in plasma and SOD in serum and liver were significantly increased by G-Rb (100, 200 mg x kg(-1)) in experimental hyperlipidemia rats. In addition, G-Rb could decrease TC/HDL-c, LDLc/HDL-c ratio, increase PGI2/TXA2 ratio and inhibit fat accumulation in liver.

CONCLUSIONG-Rb could have anti-arteriosclerosis effect by improving cholesterol and lipoprotein-cholesterol metabolism, suppressing lipid peroxidation, increasing anti-oxidase activity and PGI2/TXA2 ratio.

OBJECTIVETo observe the protective effect of compound acanthopanax senticosus injection (CASI) on myocardial ischemia-reperfusion arrhythmia in rats.

METHODThe myocardial ischemia-reperfusion model was induced by 30 min coronary occulusion and 60 min reperfusion in openchest anesthetized rats. The changes of arrhythmia with electrocardiogram lead II, the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), the contents of malondialdehyde (MDA) and Ca2+ in myocardium were determined.

RESULTIn rats treated by CASI (in a dosage of 25, 50 and 100 mg x kg(-1) femoral vein infusion at 30 min after coronary occulusion), the incidence of myocardial ischemia-reperfusion ventricular arrhythmias, for instance the ventricular tachycardia (VT) and ventricular fibrillation (Vf), was effectively prevented, the appearing time of arrhythmia was delayed and the duration of arrhythmia was shortened, while the elevated ST segment lowered as well. At the same time, the contents of myocardial Ca2+ and MDA were decreased significantly as well as the activities of myocardial SOD and GSH-Px increased markedly.

CONCLUSIONCASI is of protective effect on myocardial ischemia-reperfusion arrhythmia, which may be related to scavenging the oxygen free radicals and Ca2+ overload formed during reperfusion.

Objective To discuss the treatment of ureteropelvic junction obstruction by laparoscopic pyeloplasty. Methods A retrospective review of consecutive laparoscopic pyeloplasty in 102 patients between September 2001 and December 2007 was performed. The ureterpelvic junction was dissected and the obstruction portion was excised. Anastomosis was then performed through the ureter and the renal pelvis walls with a stent. Results The mean operating time was 120 min and the average blood loss was 80ml. No major complication occurred intraoperative. The drainage was removed in 3-10 days. The average hospital stay was 8.5 days. The stent was kept for 30-60 days. IVU and B ultrasound examination revealed that the hydronephrosis alleviated during the follow-up and no anastomosis stricture occurred. Conclusions Laparoscopic dismembered pyeloplasty could provide lower morbidity, shorter hospital stay, and faster convalescence. It could be an effective treatment for ureteropelvic junction obstruction.

OBJECTIVETo analyze the expression of MAP2K4 and vimentin in human endometrial carcinoma (EC) and their association with the clinicopathological features and prognosis of the patients.

METHODSMAP2K4 and vimentin expressions were detected immunohistochemically in paraffin-embedded tissue sections from 128 patients with EC, and the correlation of MAP2K4 and vimentin expressions with the clinicopathological factors of the patients was analyzed.

RESULTSMAP2K4 and vimentin proteins were positively expressed in 49 (38.3%) and 83 (64.8%) of the patients, respectively. A positive expression of MAP2K4 was negatively correlated with FIGO stage of the tumor (P=0.010) and lymph node status (P=0.016); a positive expression of vimentin was positively correlated with FIGO stage of the tumor (P=0.025), histological grades (P=0.017), depth of myometrial invasion (P=0.044) and lymph node status (P=0.032). MAP2K4 was inversely associated with vimentin expression in EC(r=-0.598, P<0.001). Patients positive for MAP2K4 tended to have a higher overall survival rate (P=0.002), and those positive for vimentin tended to have a lower overall survival rate (P=0.007); patients positive for MAP2K4 but negative for vimentin had the longest survival time, while those negative for MAP2K4 and positive for vimentin had lowest survival rate (P=0.004).

CONCLUSIONDetection of MAP2K4 and vimentin might help in early diagnosis and prognostic evaluation of patients with EC.

OBJECTIVETo evaluate the effect of induction chemotherapy on the patients with moderate tongue squamous cell carcinoma and to investigate the factors that influence prognosis of these patients.

METHODSOne hundred and twenty two patients with moderate tongue squamous cell carcinoma (stage II-III, T2-3 N0/T1-3N1), treated from Jan. 1990 to Dec. 1999 were retrospectively reviewed. Among them, 69 and 53 patients were received operation alone and operation after induction chemotherapy respectively [cisplatin + 5-fluorouracil + bleomycin-A5 (PBF), 17 cases; bleomycin-A5, 36 cases]. Survival rate was estimated by Kaplan-Meier method. Multivariate analysis by the Cox proportional hazard model.

RESULTSThe mean follow-time of all patients were (79.9 +/- 49.8) (x +/- s) months (range: 7 to 177 months), and 45 patients died (including 5 lost to follow up) , 66 of 77 patients alive followed more than 5 years. The overall 3-year and 5-year survival rate were 79.4% and 69. 0% respectively. The overall 3-year and 5-year free-disease survival rate were 71.7% and 66. 3% respectively. The survival rate of 3-year and 5-year was 82.5% and 73.1% respectively for the group of operation alone; 82.4% and 70.1% respectively for the group of operation after induction chemotherapy with PBF, 72.2% and 61.1% respectively for the group of operation after induction chemotherapy with bleomycin-A5; and there were no significant difference between the above three groups (chi2 = 0.42, P = 0.8106). The locoregional recurrence rate were 30.4%, 41.2% and 38.9% for the operation alone group, operation after PBF induction chemotherapy group and operation after bleomycin-A5 induction chemotherapy group respectively. No significant benefit on decreasing locoregional recurrence (chi2 = 1.148, P = 0.563) or distant metastasis rate (chi2 = 2.305, P = 0.316) were found by induction chemotherapy by univariate analysis. Using multivariate analysis, risk factor that independently influence survival was the recurrence.

CONCLUSIONSRisk factors that independently influence survival of moderate tongue squamous cell carcinoma was the locoregional recurrence. No significant benefit on improving survival rate or decreasing locoregional recurrence or metastasis rate were found by induction chemotherapy, there was no difference between the two induction chemotherapy schemes on the survival rate or locoregional recurrence or metastasis rate of these patients.

OBJECTIVETo investigate the association of the risk of prostate cancer (PCa) with the polymorphism of the CYP2E1 gene, smoking and drinking, and to explore the joint role of genes and living habits in PCa pathogenesis.

METHODSWe conducted a case-control study on 109 PCa patients and 202 age-matched non-PCa male controls, and detected the polymorphisms of CYP2E1 Rsa I and Pst I sites by PCR-RFLP using DNA from peripheral blood lymphocytes.

RESULTSThe history of deep smoking (OR = 2.29, 95% CI: 1.28 - 4.09) or heavy smoking (OR = 1.81, 95% CI: 1.02 - 3.22) was a risk factor. The CYP2E1 C1/C1 genotype significantly increased the risk of PCa (OR = 1.71, 95% CI: 1.04 - 2.82) and apparently interacted with drinking (OR = 2.21, 95% CI: 1.06 - 4.59). Heavy smokers with the C1/C1 genotype showed an increased risk of PCa (OR = 2.80, 95% CI: 1.20 - 6.56), as compared with non-smokers carrying the genotype of C1/C2 or C2/C2.

CONCLUSIONThe risk of PCa obviously increases in individuals with both the CYP2E1 C1/C1 genotype and the habit of smoking or drinking, and it has a significant positive correlation with the dose of tobacco exposure.

OBJECTIVESTumor necrosis factor-alpha (TNF-alpha) may play an important role in host's immune response to mycobacterium tuberculosis (M. tuberculosis) infection. This study was to investigate the association of TNF-alpha gene polymorphism with pulmonary tuberculosis (TB) among patients with coal worker's pneumoconiosis (CWP).

METHODSA case-control study was conducted in 113 patients with confirmed CWP complicated with pulmonary TB and 113 non-TB controls with CWP. They were matched in gender, age, job, and stage of pneumoconiosis. All participants were interviewed with questionnaires and their blood specimens were collected for genetic determination with informed consent. The TNF-alpha gene polymorphism was determined with polymerase chain reaction of restriction fragment length polymorphism (PCR-RFLP). Frequency of genotypes was assessed for Hardy-Weinberg equilibrium by chi-square test or Fisher's exact probability. Factors influencing the association of individual susceptibility with pulmonary TB were evaluated with logistic regression analysis. Gene-environment interaction was evaluated by a multiplicative model with combined OR. All data were analyzed using SAS version 8.2 software.

RESULTSNo significant difference in frequency of the TNF-alpha-308 genotype was found between CWP complicated with pulmonary TB and non-TB controls (chi2 = 5.44, P = 0.07). But difference in frequency of the TNF-alpha-308 A allele was identified between them (chi2 = 5.14, P = 0.02). No significant difference in frequencies of the TNF-alpha-238 genotype and allele (P = 0.23 and P = 0.09, respectively) was found between cases and controls either, with combined (GG and AA) OR of 3.96 (95% confidence interval of 1.30-12.09) at the -308 locus of the TNF-alpha gene, as compared to combination of the TNF-alpha-238 GG and TNF-alpha-308 GG genotypes. Multivariate-adjusted odds ratio of the TNF-alpha-238 GG and TNF-alpha-308 GA genotypes was 1.98 (95% CI of 1.06-3.71) for risk for pulmonary TB in patients with CWP. There was a synergic interaction between the TNF-alpha-308 GG genotype and body mass index (OR = 4.92), as well as an interaction between the TNF-alpha-308 GG genotype and history of BCG immunization or history of TB exposure. And, the interaction of the TNF-alpha-238 GG genotype and history of BCG immunization or TB exposure with risk for pulmonary TB in them was also indicated.

CONCLUSIONSTNF-alpha-308 A allele is associated with an elevated risk for pulmonary TB, whereas TNF-alpha-238 A allele was otherwise.
