Objective To observe the efficacy of 3-dimensional image recombinant guidance in treatment of portal hypertension.Methods A total of 73 cases of portal hypertension were randomized into study and control groups: In study group(n=37),3DCT or MRA imaging display of whole portal venous system was used as guide in selecting portoazygos vein disconnection(P-AVD) operation;in control group(n=36),the classic P-AVD operation was performed.The postoperative complication rate and the degree of amelioration of esophageal varices were cbserved.Results Compared with the control group,the short term rebleeding rate in observation group(0.00%,0/37) was lower than that in control group(11.11%,4/36),improvement rate of esophageal varices in observation group(100%,37/37) was higher than that in control group(86.11%,31/36),and the aggregate rate of portal hypertensive gastric disease and esophageal varices in observation group(0.00%,0/36)was lower than that in control group(13.9%,5/36).There was a statistical difference between the two groups(all P

Background and purpose:Arsenic trioxide(As_(2)O_(3)) injection actually has an effect on solid tumors such as hepatoma in the clinic.In order to find out its mechanism of action,we studied the action of arsenic trioxide injection on angiogenesis of chick embryo chrioallantoic membrane(CAM).Methods:The effect of arsenic trioxide injection on angiogenesis was investigated by CAM model and computer image analysis.Results:Administered at three different concentrations of arsenic trioxide injection at 10,20 and 40,3 days later,the vessel area were 25.66%?4.17%,24.74%?2.54% and 21.51%?6.70%,respectively.Compared to the NS control group(vessel area was 30.68%?(4.64%)),there was an obvious difference(P0.05 among the three different concentration groups).Conclusions:arsenic trioxide injection has a strong inhibitory effect on angiogenesis,which may be used in suppressing cancer angiogenesis.

Objective To establish loop-mediated isothermal amplification(LAMP)method for detecting Streptococcus pneumoniae in clinical samples.Methods Four Streptococcus pneumoniae-specific LAMP primers were designed according to the published sequence of strain R6(GenBank accession number AE008540).Genomie DNA in positive blood cultures was extracted by nanidine hydrochloride and benzene-methanol.Then lytA was amplified by LAMP at 63℃ for 45 minutes.We observed the turbidity in thereaction tube.For further confirmation.The amplified products were also detected using electrophoresis in 2% agarose gels,followed by ethidium bromide staining.Resuits 16 strains of Streptococcus pneumoniae were detected in 196 positive blood cuhure bottles by LAMP.Compared with traditional method.It8 sensitivity and specificity were both 100%and the detection could be finished in an hour.The assay had a minimum detection limit of 102 CFU/m1.Conclusions This IJAMP-based assay is simple,rapid.Sensitive and specific.It can be used to detect trept OCOCCUS pneumoniae in clinical samples.

Objective The indication of hysterectomy in obstetrics emergency was studied in order to defend and decrease the incidence of hysterectomy.Method 27 cases with hysterectomy in obstetric emergency were retrospectively analyzed.Results The all indication of 27 cases of hysterectomy was endometrorrhagia in obstetric emergency.The first cause of endometrorrhagia was placental complication,the second cause was puerperal disseminated intravascular coagulation,the third cause was puerperal uterine anonym.Conclusion In order to decrease the incidence of hysterectomy in obstetric emergency,the family planning and health work of perinatal period should be done goodly,the antenatal examination should be strengthened and disseminated intravascular coagulation should be made a diagnosis and treatment timely.

Objective To investigate the role of osteopontin (OPN) in cholesterol gallstone formation.MethodsGallbladder bile was obtained from patients with cholelithiasis (n=36,the experimental group) and from donors of liver transplantation (n=19,the control group).OPN,calcium ion and lipid were analysed quantitively.The nucleating role of OPN in bile was evaluated using nucleating time (NT) approach.ResultsOPN inhibited cholesterol nucleation in a dose dependent manner.OPN (50 μg/ml and 100 μg/ml) prolonged NT by 48.90％ (91.51％) and 17.07％ (32.93％) in lithogenic and control bile,respectively.OPN (100 μg/ml) also inhibited the nucleating effect induced by calcium ion.Furthermore,a combination of OPN (50 μg/ml) and calcium prolonged NT by 75.78％ and 33.96％ in lithogenic and control bile,respectively.A combination of OPN (100 μg/ml) and calcium prolonged NT by 125.9％ and 62.26％ in the 2 groups.The contents of osteopontin and calcium were significantly lower in lithogenic bile than control bile (P＜0.05).On the other hand,the cholesterol saturation index and the contents of cholesterol,phospholipid and bile acid were significantly higher (P＜0.05).ConclusionsOPN inhibited cholesterol gallstone formation.It may be involved in the pathogenesis of cholelithiasis.

Objective To investigate the dynamic changes of osteopontin (OPN) in the guinea pig model of cholesterol gallstone disease.Methods Forty-four guinea pigs were randomly assigned to cholesterol gallstone group and control group.The animals were sequentially killed on Day 7,14,28,42,56 and 70 after operation.The expressions of OPN mRNA in gallbladder and liver tissues were detected by real-time PCR.The changes of OPN,mucin,α1-acid glycoprotein (AAP) and apolipoprotein A1 (APOA1) in bile and blood plasma were detected by ELISA kits.Results The expression of OPN mRNA in gallbladder and liver tissues increased gradually and reached the peak in the 6th week,and then decreased.The increased expression of OPN in bile in the gallstone group started from the 1st week and reached the peak in the 6th week (P ＜ 0.05),which gradually decreased to the baseline in the 10th week (P ＞ 0.05).The expressions of OPN in bile and blood demonstrated similar trends,while the peak time in blood samples was much earlier (4th week).The changes of APOA1 in bile and blood were similar to OPN,although there was no advanced peak value in blood.The levels of mucin and AAP in bile and blood increased after operation,and were kept at high level throughout the study.Conclusions OPN is involved in the whole process of cholesterol gallstone formation,which may be associated with other nucleation-active factors.
