Purpose:To evaluate the role of CT in diagnosing local recurrence after surgery of gastric carcinoma. Methods:Two groups of 51 patients after surgery of gastric carcinoma were prospectively studied by means of CT performed with the water as oral contrast,hypotonic agent and dynamic or spiral CT technique. 15 patients proved to be without local recurrence measured the thickness and observed the CT findings of anastomosis stoma ,36 patients proved to have local recurrence ,those patients included male 21 and female 15.Results:90.19%(46/51)anastomosis stoma was clearly demonstrated ,and 32 lesions was detected and confirmed the diagnosis in 29 of 32 cases . The CT findings of local recurrence after gastric resection for gastric cancer were irregular gastric wall thickening ( n =14),local mass ( n =6) and mixed lesions ( n =9).Conclusions:Using the optimal technique can improve the detectability and accuracy of CT for diagnosing the local recurrence after surgery for gastric carcinoma.

Objective This study was to evaluate a new radical resection of hepatic hydatidosis. MethodSince 1999, total subadventitial cystectomy through the intraadventitial space of the hepatic hydatid cyst was performed on thirty patients with 45 liver hydatid cysts. Results The procedure was successful in all cases with no intraoperative rupture of the cysts. The average blood loss per cyst was 20?ml. There was no operative mortality, nor postoperative complications. Twenty one cases were followed up for an average period of 11 months with no recurrence. Conclusions The results indicate that the new procedure is a safe and radical alternative for the treatment of hepatic hydatidosis.

Objective To study the state of oxidative stress induced by sodium arsenite (NaAsO2) in SV-HUC-1 cell. Methods MTT assay was used to evaluate the viability of the cells. The level of ROS was detected by staining cells with DCFH-DA. The content of GSH and MDA were measured by DTNB and thiobarbituric acid methods. The activity of SOD was measured by xanthine oxidase method. Results Compared with the control group, the viability cells decreased in all the treated groups (P0.05), the activity of SOD in all the treated groups was significantly decreased (P

Objective To explore the significance of IL-17 and IL-10 in patients with different types of hepatic cystic echinococcosis ( CE ) in cyst stages , to investigate the values of evaluation of hydatid cyst activity . Methods 33 patients with hepatic hydatid disease and 21 healthy people (control group) were enrolled, divided into 4 groups, according to WHO ultrasonic classification for CE:Control group (n=21), CEⅠ,Ⅱgroup (active, n=14), CEⅢgroup (transitional, n=10), and CEⅣ,Ⅴgroup (inactive, n=9). The serum concentrations of IL-17 and IL-10 were measured by enzyme-linked immunosorbent assay. Results Serum levels of IL-17 in CEⅢgroup were significantly higher than other groups (P<0.05). There were no significant difference in serum IL-17 levels between CEⅠ,Ⅱgroup [(38.57 ± 3.83) pg/mL] and CEⅣ,Ⅴgroup [(40.22 ± 5.15) pg/mL]. Serum levels of IL-10 were significantly higher in CEⅢgroup [(14.65 ± 2.15) pg/mL] than CEⅠ,Ⅱgroup [(11.38 ± 0.71) pg/mL] (P<0.05), while CEⅠ,Ⅱgroup were significantly higher than CEⅣ,Ⅴgroup [(7.60 ± 0.46) pg/mL] (P<0.05). There were no significant difference of IL-17/IL-10 ratio between CEⅠ, Ⅱgroup (3.44 ± 1.04) and CEⅢgroup (4.60 ± 2.40), and there were no significant difference of IL-17/IL-10 ratio between CEⅢgroup and CEⅣ,Ⅴgroup (5.39 ± 1.95). IL-17/IL-10 ratio in CEⅠ, Ⅱgroup was significantly lower than CEⅣ, Ⅴgroup (P<0.05). The serum concentrations of IL-17 has no correlation with IL-10 in different cyst stages. Conclusions The synergy effect of IL-17 and IL-10 may play the certain role to promote the parasite progress. Neither IL-17 nor IL-10 level could be as an independent marker of echinococcal cysts activity, while IL-17/IL-10 ratio reflect the hydatid cyst activity in certain degree, but as a echinococcal cysts activity marker, further evidence should be needed.

Objective To study the changes of serum high mobility group box 1 protein ( HMGB-1 ) in patients with traumatic acute lung injury (ALI) and determine its correlations with MODS,acute physiology and chronic health evaluation ( APACHE Ⅱ ) scores and whether it can predict the incidence of MODS and mortality.Methods Forty cases of ALI were divided into MODS group (n =13) and nonMODS group (n =27) according to the MODS evaluation standard.The serum HMGB-1 was determined in the control group ( 10 healthy persons) and the MODS and non-MODS groups at days 1,4 and 7.The MODS and APACHE Ⅱ scores were also evaluated.Results Between the groups,the HMGB-1 level at days 1,4 and 7 in non-MODS group was higher than that in the control group,while lower than that in MODS group (P＜0.05).Within the non-MODS group,the expression of HMGB-1 showed a high level at day 4 compared with that at day 1 ( P ＜0.01 ) ; the HMGB-1 showed a low level at day 7 with clinical symptom improvement compared with that at day 4,and was even lower than that at day 1 ( P ＜ 0.01 ).Within the MODS group,the serum HMGB-1 level was significantly increased,and continued for several days; the HMGB-1 was decreased slightly at day 7 in comparison with that at day 4,but was still higher than that at day 1.The difference of MODS and APACHE Ⅱ score was significant,with the dynamic change of HMGB-1 level at days 1,4 and 7 after traumatic ALI.The correlative analysis showed that HMGB-1 expression level was remarkably related with MODS score and APACHE Ⅱ score.Conclusions HMGB-1 shows a high expression in patients with traumatic ALI.As a late mediator of inflammation,HMGB-1 usually increases relatively late and lasts for a long duration.HMGB-I level and concurrency MODS are closely related.Routine test of serum HMGB-1 level and joint assessment of MODS and APACHE Ⅱ score are contributive to the prediction of organ dysfunction after traumatic ALI.

Liver tissues around hydatid from 8 patients with cystic echinococcosis were observed by transmission electron microscopy,normal hepatic tissues of 6 cases were used as control.The results demonstrated predominant atrophy and necrosis of hepatocytes.These changes seem to be the major hepatic lesion in cystic echinococcosis.

We detected the seroprevalence of Toxoplasma gondii (T.gondii) in the wild birds in northeast China.The wild bird's blood was collected from the cutaneous ulnar vein and the serum was isolated and used for detection of anti T.gondii antibody by modified agglutination test (MAT).Results showed that totally 179 birds' serum samples were collected.Twenty serum samples (11.17％) were positive with T.gondii antibody,which belonged to 9 orders,17 families and 31 species.The seroprevalence against T.gondii was about 5.26％ (1/19) in Columbiformes,9.09％ (9/99) in Passeriformes,14.29％ (3/21) in Falconiformes,15.00％ (5/22) in Piciformes,16.67％ (1/6) in Coraciiformes,and 25.00％ (1/4) in Anseriformes.Based on their feeding behavior,the seroprevalence was 12.00％ (3/25) in carnivorous wild birds,10.60％ (15/141) in omnivorous wild birds,and 15.38％ (2/13) in the wild birds feeding on aquatic animals or plants.These wild birds also can be sorted as migratory and sedentary (non-migratory) according to their migration habits,and the serum positivity was 11.67％ (14/120),and 10.71％ (6/59) respectively.The seroprevalence against Toxoplasma gondii in wild birds in northeast China is about 11.17％,which indicates a common infection of Toxoplasma gondii in wild birds.

Objective The calcium oxalate stone is the most common type of the kidney stones.By building the rat renal calcium oxalate stone model, preliminary study the function of CaSR-Claudin14 regulating pathways on renal calcium oxalate stone for-mation model in rats. Methods 30 Male S-D rats were randomly divided into control group (n=15) and model group (n=15). Adult male S-D rats were given ethylene glycol and ammonium chloride to induce urolithiasis.Application of full automatic biochemical analyzer to test rat renal function and the changes of urine biochemical index.Immunohistochemistry was used to detect the expression of CaSR protein;RT-PCR was used to detect the Claudin-14 mRNA expression;Western Blotting was used to detect the expression of CaSR and Claudin-14 protein respectively. Results By observing model group has large stones crystallization under light microsco-py;model group rats 24 h urine calcium are significantly higher than control group([9.66 ±1.10]mmol vs [3.26 ±0.60]mmol, P<0.01); and model group 24 h urine volume are significantly higher than control group ([21.27 ±1.08]mL vs [13.2 ±0.55]mL, P<0.01 ); and urinary PH has no significant difference between the groups( P >0.05 ) .Expression of Claudin-14 mRNA in the model group is significantly higher than normal control group([0.150 ± 0.004] vs [0.047 ±0.008], P<0.01); Expression of Claudin-14 protein in the model group is significantly higher than normal control group([1.526 ±0.089] vs 0, P<0.01).Expression of CaSR protein in the model group is significantly higher than normal control group([6.697 ±0.051] vs [5.016 ±0.053], P<0.05). Conclusion CaSR can raise the expression of Claudin-14, increase re-nal tubular urinary calcium excretion to promote renal calcium oxalate stone formation.
