Objective To compare and anlyze the applications of microcolumn gel test (MGT)and the tube anti -globulin test (TAT)for detection of three hemolytic tests.Methods Microcolumn gel test and tube anti -globulin test were used in three tests with a total of 160 cases of blood speciments of newborn who had blood group in-compatibility with their mothers:direct anti -globulin test,free test and elution test,then the data were analyzed statis-tically.Results The positive rates of direct anti -globulin test of MGT and TAT were 30.0% and 12.5%(χ2 =14.64,P <0.05);The positive rates of free test of MGT and TAT were 47.5% and 25.0%(χ2 =17.53,P <0.05), respectively;The positive rates of elution test of MGT and TAT were 62.5% and 30.0%(χ2 =33.99,P <0.05). There was statistically significant difference between two methods in three tests.Conclusion MGT has the advantages of quickness,simplicity,high sensitivity,convenience,needs less sample,high repeatability,direct judging of the re-sults,which is better than TAT in three hemolytic tests.

Objective To investigate the effects of Tirofiban on the expression of matrix metalloproteinase(MMP-9)and sCD40L in patients with acute coronary syndrome(ACS)after percutaneous coronary intervention(PCI)and to explore the potential mechanism of anti-artherosclerosis and stabilize plaque by Tirofiban.Methods Eighty-six patients with ACS were enrolled and were randomly divided into the control group and the Tirofiban group with different time periods after PCI.The expression of MMP-9 and sCD40L were tested by ELISA at 6 h,12 h,24 h,36 h after PCI.Results After application of Tirofiban 6 h,12 h,24 h,36 h,the expression of MMP-9 decreased from(228.25 ±0.015)ug/L to(53.56 ±0.02)μg/L and the expression of sCD40L decreased from(321.12 ±0.02)ng/L to(123.32 ±0.02)ng/L,compared with the control group,the difference was significant(P ＜ 0.05).Conclusions Tirofiban can inhibite the expression of sCD40L and MMP-9,the inhibition of the expression of MMP-9 may be related to the CD40/CD40L pathway.This effect may be one of the mechanism of reducing atherosclerotic plaque inflammation and preventing plaque rupture by Tirofiban.

Objective To investigate the effects of Schistosoma japonicum infection on selective activation of macrophages and insulin resistance in liver tissues of mice with high-fat diet induced obesity and the possible mechanism. Methods Thirty-six male C57BL/ 6J mice were randomly divided into 3 groups in-cluding normal control group(NC group,n=12),high-fat diet feeding group(HF group,n=12)and high-fat diet feeding with Schistosoma japonicum infection group(HSj group,n=12). Specimens were collected 6 and 12 weeks after high-fat diet feeding. The levels of fasting blood glucose(FBG),fasting plasma insulin (FINS)and homeostasis model assessment for insulin resistance index(HOMA-IR)were detected. The ex-pression of interleukin-6(IL-6),arginase-1(Arg-1)and found in inflammatory zone-1(Fizz-1)at mRNA and protein levels were detected by semi-quantitative reverse transcription polymerase chain reaction(RT-PCR)and immunohistochemistry,respectively. Results The mice from HF group showed higher levels of HOMA-IR than those form NC group and HSj group by the end of 6 and 12 weeks after infection(P﹤0. 05). The levels of HOMA-IR in mice from HF group were increased by the end of week 12 after infection as com-pared with those at week 6(P>0. 05). The levels of IL-6 in mice from both HF group and HSj group were higher than those from NC group by the end of week 6 after infection(P﹤0. 05). Higher levels of IL-6 were detected in mice from HF group as compared with those from HSj group and NC group by the end of week 12 after infection(P﹤0. 05). The expression of Arg-1 and Fizz-1 in mice form HF group were lower than those from NC group by the end of 6 and 12 weeks after infection(P﹤0. 05). Arg-1 was highly expressed in mice form HSj group,followed by those from NC and HF groups 12 weeks after infection. The expression of Fizz-1 in mice from HSj group was the highest among the three groups by the end of week 6 and 12 after infection (P﹤0. 05). Conclusion The proinflammatory effects on mice with diet induced obesity were induced dur-ing acute infection of Schistosoma japonicum cercariae(6 weeks). The chronic infection of Schistosoma ja-ponicum cercariae(12 weeks)might be helpful in reversing hepatic insulin resistance in mice with diet in-duced obesity by changing the polarity of macrophages in liver tissues.

Objective To evaluate the effects of sevoflurane postconditioning on the oncosis and apoptosis in cardiomyocytes during ischemia-reperfusion (I/R) in isolated rat hearts and the role of extracellular signalregulated protein kinase 1/2 (ERK1/2) signal transduction pathway in it.Methods Seventy-two isolated rat hearts perfused in a Langendorff apparatus were randomly divided into 6 groups (n =12 each) using a random number table:sham operation group (group S),myocardial I/R group (group I/R),sevoflurane postconditioning group (group SP),PD98059 vehicle dimethyl sulfoxide (DMSO) group (group DMSO),selective ERK1/2 inhibitor PD98059 group (group PD),and sevoflurane postconditioning + PD98059 group (group SP + PD).The hearts were subjected to ischemia for 30 min followed by 2 h reperfusion in the other groups except group S.In SP,DMSO and PD groups,the hearts were perfused with K-H solution saturated with 3.0％ sevoflurane,DMSO (＜0.2％) and PD98059 (20 μmol/L),respectively,for 15 min starting from the end of ischemia until 15 min of reperfusion,and then with plain K-H solution for 105 min.In group SP+ PD,the hearts were perfused with K-H solution saturated with 3.0％ sevoflurane and PD98059 for 15 min starting from the end of ischemia until 15 min of reperfusion.Myocardial infarct size and expression of porimin and caspase-8 proteins (by Western blot) were measured at the end of reperfusion.Results Compared with S group,the myocardial infarct size was significantly increased,and the expression of porimin and caspase-8 proteins was up-regulated in the other groups (P ＜ 0.05).Compared with I/R group,the myocardial infarct size was significantly decreased,and the expression of porimin and caspase-8 proteins was down-regulated in group SP (P ＜ 0.05),and no significant changes were found in the other groups (P ＞ 0.05).Conclusion Sevoflurane postconditioning can activate ERK1/2 signal transduction pathway and inhibit the oncosis and apoptosis in cardiomyocytes,thus attenuating I/R injury in isolated rat hearts.

Two hundred cases of early pregnant women to receiveartificial abortion were randomly divided into 4groups,viz.analgesic solution,dicaine,normal saline,and blank control groups of which the action on dilata-tion of uterus and of mitigating the comprehensive re-actions to artificval abortion were observed.Resultsrevealed that the analgesic solution and dicaine groupshad better effect on dilatation of uterus and ameliorat-ing the reactions of artificial abortion,analgesic solu-tion was especially good at mitigating the comprehen-sive reactions to artificial abortion than the dicainegroup.

OBJECTIVETo find a sensitive index of early injury of the nervous system in lead-exposed workers and to provide a scientific basis for establishing an efficient occupational health surveillance route.

METHODSA total of 317 lead-exposed workers (blood lead levels: 26.90∼ 912.80 µg/L, determined with the atomic absorption spectrum) were divided into four groups according to the normal blood lead level (201 µg/L), acceptable upper limit of blood lead (400 µg/L), and diagnostic value (600 µg/L). The motor nerve conduction function was examined and analyzed by one-way ANOVA.

RESULTSThe distal latency and amplitude of the median nerve were significantly different between groups. The median distal latency of the highest blood lead group (>600 µg/L) was 3.63 ms, which was significantly longer than the average level (3.30 ms), and the median nerve amplitude of the highest blood lead group was 5.63 µV, significantly lower than the average level (7.27 µV). No significant difference was found between different groups in motor conduction velocity. Significant difference was found in ulnar nerve amplitude between groups. The ulnar nerve amplitude of the highest blood lead group was 4.31 µV, significantly lower than the average level (4.87 µV). No significant differences were observed in other parameters between groups.

CONCLUSIONThe distal latency and amplitude of the median nerve can be used as a sensitive index for the diagnosis of early subclinical motor nerve injury in lead?exposed workers.
