OBJECTIVETo explore the mechanism of anti-proliferative effect of indomethacin (IN) on chronic myelogenous leukemia (CML) cells.

METHODSMTT was applied to assay CML cells viability under IN intervention. STAT1, STAT5 proteins were analyzed by Western blot, the expressions of phosphorylated STAT1 or STAT5 by immunoprecipitation combined with Western blot, the cellular localization of p-STATs proteins by indirect immunofluorescence technique, and the detection of Bcl-X(L) and COX-2 protein by Western blot.

RESULTSIN could significantly inhibit the viability of CML cells. 0 approximately 400 micromol/L of IN could down-regulate the expression of p-STAT1 or p-STAT5 in a dose-response manner, p-STATs were distributed mainly in the nucleus as scattering spots. The expression of COX-2 protein could be detected in K562 cells. Both Bcl-X(L) and COX-2 proteins could be inhibited by IN in a dose-dependent manner.

CONCLUSIONSIN could significantly inhibit the proliferation of CML cells, the mechanism of which might be related to the suppression of STATs/Bcl-X(L) signal transduction pathway. There exists COX-2 protein expression in K562 cells, the anti-leukemia effect of IN was possibly dependent on COX-2 pathway.

Objective To assess the continent diversion results of sigma rectum pouch after radical cystectomy. Methods The reconstruction of bladder with sigmoid was modified for treatment of 18 cases of bladder tumor.The intestine was incised over a length of 20～24 cm with the junction of sigmoid colon and rectum as the midpoint so as to create a low pressure reservoir for urine and side-to-side anastomosis was performed on the posterior borders of the rectosigmoid wall.Submucosal tunnel modified technique was em- ployed in antireflux urethral implantation,Urination has been controlled by anal sphincter.Results About 80 minutes was spent to finish a new low pressure pouch after radical cystectomy.Among 18 patients with this op- eration,the controlled emiction were good after pull out the anal duct and"J"stent in 1 week to 2 months.Af- ter 2 months,the times of urination is stable,4～5 times in daytime and 1～3 times during nighttime.Two pa- tients had nocturnal enuresis and the symptom vanished after 2 months. One patient had adhesive ileus, two patients had hyperchloremia acidosis and kaliopenia,one patient had urethral stump cancer.There is no com- plication as anastomotic block,renal function lesion and severe upper urinary tract infection. Conclusion This operative method was easy,emiction control was well,and with higher quality of life for patients.It is al- so a better alternative diversion procedure that would be easily accepted.

Objective To investigate the value and clinical significance of congenital heart diseases (CHD)detection in twins.Methods A total of 1103 twins were included in this study(127 twins were at high risk for CHD).The fetal hearts were scanned by ultrasound using Yagel's heart examination method. Autopsies were done when the pregnancy was terminated.And blood samples from fetal hearts or umbilical veins were used to evaluate fetal chromosomes.A close follow-up was conducted for normal heart cases and another heart examination was done within three months after birth.Results(1)12 twins(1.09%,12/ 1103)had CHD.Among them,4 cases were from the high risk for CHD group(33.3%,4/12),and 8 cases(66.7%,8/12)were from the low risk pregnancy group.(2)Two twins suffered from the same CHD (one pair were both TOF,and the other pair were both rhabdomyoma).One pair of twins had different abnormalities(one baby was TOF,and the other was duodenal atresia with a normal heart).All three pairs of twins chose termination and autopsies were conducted.Unanimous conclusions between prenatal ultrasound and autopsy were obtained.Nine twins were CHD in one baby and a normal heart in the other baby.Seven of them had the same conclusion after delivery.(3)Two twins with CHD were found with fetal abnormal chromosome.(4)1091 cases were not found having any abnormality,however,one fetus from one twin pair was diagnosed with ventricular septal defect(VSD)with abnormal chromosome after birth,and one fetus from another twin pair had patency of ductus arteriosus after birth.(5)The sensitivity of Yagel's heart examination was 82.4% and specificity was 100% in twins.Conclusion Yagel's heart examination is an effective and time-saving method to scan fetal hearts in twins.

OBJECTIVETo investigate the effect of bufalin on nucleus-mitochondria localization of human telomerase reverse transcriptase(hTERT) by exploring its effect on proliferation and apoptosis in human esophageal squamous carcinoma EC9706 cells.

METHODSEC9706 cells were treated with bufalin at various concentrations, and then the cell growth inhibition of EC9706 cells was examined by CCK-8 assay and the 50% inhibitory concentration (IC(50)) was calculated.Cell cycle analysis was performed by flow cytometry with PI staining, and nucleus morphology of apoptosis were observed by fluorescence microscopy with Hoechst 33342 staining. The apoptotic index was measured by flow cytometry with Annexin V-FITC/PI double staining. hTERT subcellular localization and protein expression were determined by Western blotting and multiple immunofluorescence labling combined with laser confocal scanning microscopy.

RESULTSThe proliferation of EC 9706 cells was significantly inhibited by bufalin along with the increase of processing time and concentrations (p<0.01). After the EC9706 cells were exposed to 100 nmol/L bufalin,the number of cells gradually decreased in G(1) phase and increased in S and G(2)/M phases(p<0.05). The typical nucleus morphological changes of apoptosis were observed and the apoptotic index was increased(p<0.01). The expression of hTERT decreased in nucleus but increased in mitochondria(p<0.05).

CONCLUSIONSBufalin can inhibit the proliferation of human esophageal squamous carcinoma EC9706 cells in a time- and dose-dependent manner. It can arrest cell cycle in S and G(2)/M phases and induce the apoptosis of EC 9706 cells. hTERT is localized in both nucleus and mitochondria,and can be partially translocated from nucleus to mitochondria during the bufalin-induced apoptosis.

OBJECTIVETo explore the influence of conventional metal materials in oral cavity on brain magnetic resonance imaging (MRI).

METHODSFour kinds of metal materials (metal ligature wire, forging hard and slotless denture, casting nichrome denture, casting copper alloy denture) in oral cavity were scanned through MRI. FSE sequence T1 weighted imaging (FSE T1), EPI diffusion-weighted imaging (DWI) sequence of ordinary, Propeller DWI imaging were used.

RESULTSIn FSE T1 sequence, metal ligature wire and forging hard and slotless denture produced serious false image, casting nichrome denture produced moderate false image, casting copper alloy denture produced only little false image. In EPI DWI sequence, obvious magnetic-sensitive false image were produced in the dissection tissue of the brain by metal ligature wire. While in Propeller DWI sequence, magnetic-sensitive false image were greatly reduced and satisfactory images were formed.

CONCLUSIONDifferent metal materials in oral cavity have different influence on the MRI. The false images produced by different metal materials are closely related to the type of the material. Magnetic-sensitive false images can be eliminated by Propeller DWI technique.

OBJECTIVETo examine the relationship between intercellular adhesion molecule-1 (ICAM-1) gene polymorphism and ischemic stroke (IS) in Chinese Zhuang populations.

METHODSThe K469E polymorphism in the exon 6 of ICAM-1 gene was detected by polymerase chain reaction-restriction fragment length polymorphism analysis and DNA sequencing in 205 patients with IS of Zhuang nationality and in 210 healthy controls, and the serum level of ICAM-1 was determined by enzyme-linked immunosorbent assay.

RESULTSThe IS group showed significantly higher serum levels of ICAM-1 than did the control group (P < 0.01). There was significant difference in frequencies of allele and genotype in K469E polymorphism between IS and control groups, respectively (P < 0.05). The K allele carriers had 1.424 times the risk of suffering from IS as compared with the E allele carriers (OR = 1.424, 95% CI: 1.071 - 1.894); the serum ICAM-1 level of E allele carriers was significantly higher than that of K allele carriers (501.24 +/- 139.56 ng/ml vs 475.17 +/- 118.35 ng/ml, P < 0.01).

CONCLUSIONThere is an association between ICAM-1 gene K469E polymorphism and IS, and E allele may be a genetic risk factor of IS among Guangxi Zhuangs, in which the ICAM-1 E allele carriers may have up-regulated expression of ICAM-1 and hence are at a higher risk of ischemic stroke.

OBJECTIVETo observe the effects of hemoperfusion on oxidative stress status and the levels of matrix metallo proteinase (MMP-2, MMP-9), tissue inhibitor of metalloproteinase (TIMP-1) in lungs, livers and kidneys in paraquat poisoning rabbits, and to explore the mechanism of therapeutic effects induced by HP on acute paraquat poisoning.

METHODSSeventy eight rabbits were randomly divided into normal control group (N group, n=6), exposure groups (PQ group, n=24), hemoperfusion treatment group (HP treatment group, n= 24) and blank control group (HP group, n=24). The PQ, HPQ and HP groups were divided into 4 observation time groups (1, 3, 7 and 21 d). N group was exposed to 5 ml normal saline and PQ group was exposed to 50 mg/kg PQ by oral gavage. In 1 h after PQ exposure, HPQ group was exposed to the activated carbon hemoperfusion for 2 h. The content or activity of MDA, SOD and GSH-Px in lungs, livers and kidneys were detected, the expression levels of MMP-2, MMP-9 and TIMP-1 were measured with immunohistochemical SP method for all groups.

RESULTSThe contents of MDA in lungs, livers and kidneys of PQ and HPQ groups decreased and the activities of SOD and GSH-Px in lungs, livers and kidneys of PQ and HPQ groups increased with observation time. The expression levels of MMP-2, MMP-9 and TIMP-1 in PQ and HPQ groups enhanced on the first day, PQ group was most obvious. Along with the observation time extended, all kinds of positive expression were still high. Compared with normal control group, the activities of serum SOD and GSH-Px in PQ and HPQ groups declined significantly, but the contents of serum MDA increased; the expression levels of MMP-2, MMP-9 and TIMP-1 in lung, liver and kidney tissues increased obviously, the ration between MMP-9 and TIMP-1 significantly increased (P < 0.05). Compared with PQ group, the activities of SOD and GSH-Px in HPQ group significantly increased, the content of MDA declined, the expression levels of MMP-2, MMP-9 and TIMP-1 in lung, liver and kidney tissues declined obviously, the ration between MMP-9 and TIMP-1 significantly declined, but higher than N group, the differences were statistically significant (P < 0.05).

CONCLUSIONThe oxidative stress and MMPs may be involved in the pathogenesis of tissue injuries induced by paraquat. The treatment with HP could obviously reduce oxidative stress and the expression levels of MMP-2, MMP-9 and TIMP-1, enhance the ration between MMP-9 and TIMP-1. So HP treatment could play a role in rescuing the PQ poisoning and protecting the organs function.

OBJECTIVETo investigate the dynamic changes of oxidative stress and nuclear factor-E2 related factor 2 (Nrf2) expression in the lung tissues of acute hydrogen sulfide (H2S) intoxicated rats and intervention effects of ulinastatin (UTI).

METHODSA total of 96 SD rats of clean grade were divided randomly into four groups: normal control group (n = 8), UTI control group (n = 8), H2S -intoxicated model group (n = 40), and UTI treatment group (n = 40). The H2S-intoxicated model group and UTI treatment group were exposed to H2S (283.515 mg/m3) by inhalation for 1h, then UTI treatment group was intraperitoneally exposed to UTI at the dose of 10(5) U/kg for 2 h. H2S-intoxicated model group and UTI treatment group were sacrificed at 2, 6, 12, 24 and 48 h after exposure, respectively. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and glutathione (GSH) in the rat lung tissues were measured. The expression levels of Nrf2 mRNA in the rat lung tissues were detected. Pathological changes of rat lung tissues were observed under a light microscope and the lung injury scores were evaluated.

RESULTSCompared with control group, the pulmonary SOD, CAT and GSH levels at 2,6 and 12 h after exposure and the pulmonary GSH-Px levels at 2, 6, 12 and 24 h after exposure in H2S-intoxicated model group significantly decreased (P < 0.05 or P < 0.01). The levels of pulmonary MDA at 2, 6, 12 and 24 h after exposure in H2S-intoxicated model group were significantly higher than those in normal control group (P < 0.01). As compared with H2S -intoxicated model group, the pulmonary GSH-Px activities at 6 and 12 h after exposure, the pulmonary CAT activities at 2, 6 and 12 h after exposure, the pulmonary GSH levels at 2, 6, 12 and 24 h after exposure and the pulmonary SOD activities at 2, 6, 12, 24 and 48 h after exposure in UTI treatment group significantly increased (P < 0.05 or P < 0.01), the pulmonary MDA levels at 2, 6 and 12 h after exposure in UTI treatment group significantly decreased (P < 0.01). The expression levels of Nrf2 mRNA at 2, 6, 12, 24 h after exposure in H2S-intoxicated model group were 0.314 +/- 0.011, 0.269 +/- 0.010, 0.246 +/- 0.011 and 0.221 +/- 0.018, respectively, which were significantly higher than those (0.149 +/- 0.012) in control group (P < 0.01). As compared with H2S-intoxicated model group, the expression levels (0.383 +/- 0.017, 0.377 +/- 0.014, 0.425 +/- 0.017, 0.407 +/- 0.011 and 0.381 +/- 0.010) of Nrf2 mRNA at 2, 6, 12, 24 and 48 h after exposure in UTI treatment group significantly increased (P < 0.01). The lung injury at 24 h after exposure in H2S-intoxicated model group was higher than that in UTI treatment group. Histopathological examination showed that the scores of lung injury at 12, 24 and 48 h after exposure in UTI treatment group was significantly lower than those in H2S-intoxicated model group (P < 0.01).

CONCLUSIONOxidative stress and Nrf2 activation may be the important factors in rat lung injury induced by H2S-intoxicated, UTI may reduce the rat lung injury and protect the rat lung from damage induced by H2S by inhibiting ROS, improving the imbalance in redox and up-regulating Nrf2 mRNA expression.
