Objective To investigate the relation of the peripheral blood C-reactive protein (CRP)and procalcitonin (PCT) and multiple organ dysfunction syndrome( MODS ) for patients with multiple trauma.Methods A total of 136 patients with multiple trauma were divided into MODS group (49 cases) and non MODS group (87 cases),and 50 healthy volunteers were chosen as control group. Peripheral blood CRP and PCT concentration were detected at different times. Results The highest concentration of peripheral blood CRP in MODS group was appeared on 48 h [(38.7 ± 2.7) mg/L], CRP concentrations in MODS group were significantly different with non MODS group and control group (P ＜0.05). The highest concentration of peripheral blood PCT in MODS group was appeared on 24 h [(20.3 ± 1.7)μ g/L], PCT concentrations in MODS group were significantly different with non MODS group and control group (P＜ 0.05). Conclusions CRP and PCT are relevant to the occurrence of MODS in trauma acute stage. The observation of peripheral blood CRP and PCT concentrations can predict the occurrence of MODS.

Purpose To investigate the expression of IGF-Ⅱand IGFBP-6 in co1orecta1 cancer,and to exp1ore the c1inica1 significance in co1orecta1 cancer. Methods IGF-Ⅱand IGFBP-6 were detected by immunohistochemistry and RT-PCR in 50 cases of co1orecta1 cancer(experimenta1 group)and 50 cases of the adjacent mucosa(contro1 group). Results (1)In the experimenta1 group,the ex-pression 1eve1 of IGF-Ⅱprotein and mRNA was significant1y higher than the contro1 group. The expression 1eve1s of IGF-Ⅱprotein and mRNA in co1orecta1 cancer were significant1y 1ower than the contro1 group.(2)The expression 1eve1s of IGF-Ⅱand IGFBP-6 were sig-nificant1y different between different tumor infi1tration depth,1ymph node metastasis,invasion depth and Duke’s stages( P<0. 05), but no difference between genders,age and the degree of tumor differentiation( P>0. 05). Conclusions There is a obvious corre1a-tion between of IGF-Ⅱ and IGFBP-6 in c1inica1 patho1ogica1 parameters in co1orecta1 cancer. Combined detection of the two markers may be the bio1ogica1 indicators of occurrence and prognosis of co1orecta1 cancer,and provide a new scheme for diagnosis and treatment of co1orecta1 cancer.

Objective To discuss the influent factors and managements of lower urinary tract injury caused by tension-free vaginal tape (TVT) procedure. Methods From Mar.2001 to Feb.2011,609stress urinary incontinence (SUI) patients were trested by TVT.Lower urinary tract injury appeared in 39 cases (6.4％),which age from 39 to 78 years (average age 52.7 ± 18.3).The history of disease was 2 to 12 years.Preoperative SUI types were 12 cases of Ⅱ type SUI,22 cases of Ⅱ/Ⅲ type SUI and 5 cases of Ⅲ type SUI.The patients who had low urinary tract injury were retrospective analyzed to figure out the causes and influent factors,and recorded the treatments and follow-ups. Results 39 patients (6.4％) suffered from low urinary tract injury,including 36 oases (5.9％) of bladder perforation and 3 cases of urethral injury.In these 39 patients,34 (87.2％) patients had history of pelvic surgeries,including 18 (52.9％) cases of total hysterectomy,9 (26.5％) cases of cesarean section delivery,4 (11.8％) cases of hysteromyomectomia and 3 (8.8％) cases of ovarian surgery.All of the 36 bladder peeroration patients were re-punctured and the catheter was kept for 4 - 5 d.Three urethral injury patients were re-punctured after the urethral rupture was sutured and the catheter was kept for 2 weeks.All the 39 patients were cured and discharged.No urinary fistula,infection or other postoperative complications occurred. Conclusions The history of pelvic surgery may be an important risk factor of the lower urinary tract injury,which should pay attention.If the bladder perforation occurred,re-puncture should be taken by adjust the direction.If there was a urethral injury,the re-puncture should be taken after the suturing of the urethral rupture.

Objective To investigate the effect of oncolytic adenovirus vector SG600-IL24expressing human melanoma differentiation associated gene-7 (mda-7/IL-24) on hepatocellular carcinoma cell lines with different metastatic potential of HepG2, SMMC7721, MHCC97L and normal liver cell line LO2. Methods The oncolytic adenovirus SG600-IL24 which carrying mda-7/IL-24 gene was transfected into hepatocellular carcinoma cell lines and normal liver cell line. The mRNA and protein expression of mda7/IL-24 in HepG2, SMMC7721, MHCC97L and LO2 cell lines was confirmed by RT-PCR,ELISA assay and Western blot respectively. MTT assay and flow cytometry were used to study tumor cell proliferation and cell cycle in vitro. Hoechst33258 and flow cytometry were studied to indicate the apoptosis effects. Results It was confirmed by RT-PCR, ELISA assay and Western-blot that the exogenous mda-7/IL-24 gene was highly expressed in HepG2, SMMC7721, MHCC97L and LO2 cell lines. MTT and apoptosis detection indicated that MDA-7/IL-24 can induce the growth suppression (the inhibition rate was 75% ±2. 5% ,86% ±3. 5% ,and promotes apoptosis ( the apoptosis rate was 56. 5% ± 4. 0% , 34. 4% ± 2. 0% , 43. 3% ± 2. 5%cell lines at G2/M phase ( the blocking rate was 35. 4% ± 4. 2% , 40. 5% ± 5. 0% , 42. 0% ± 5. 0%metastatic potential hepatocellular carcinoma cell lines but not in normal liver cell line.Conclusions Oncolytic adenovirus vector SG600-IL24 can selectively induce growth suppression, promote apoptosis in hepatocellular carcinoma lines in vitro but not in normal liver cell LO2.

Objective To investigate the levels of monocyte chemoattractant protein-1(MCP-1)in the bladder tissue and urine of female interstitial cystitis(IC)patients. Methods Thirty-five IC patients according tO the NIDDK IC diagnosis standard,20 urinary infection (UI) patients and 25 asymptomatic controls were collected.All IC patients were accepted 24 hour voiding diaries,O'LearySant IC Questionnaires,potassium sensitivity test (PST) and cystoscopy under anesthetic.RT-PCR and ELISA analyses were used to determine the levels of MCP-1 in the bladder tissue and urine specimens from women with IC、UI and controls.Immunohistochemistry staining was used to observe the distribution of MCP-1 in bladder tissue of IC. Results Urine MCP-1 was (74.1±36.9)pg/ml in IC patients,(280.65±68.9)pg/ml in UI patients and(10.8±6.9)pg/ml in asymptomatic controls(P＜0.01).Tissue MCP-1 was 76.2±24.0 in IC patients,99.5±30.1 in UI patients and 36.1±14.1 in asymptomatic controls(P＜0.01)by RT-PCR analyses.The MCP-1 degree increased in IC patients was between UI patients and asyrnptomatie controls.The severity of IC clinical symptom Was correlated with MCP1 levels. Conclusions The changes in the levels of MCP-1 are associated with IC.After excluding urinary infection,it would be useful for early diagnosis of IC by increased level of MCP-1.

Objective To investigate the application value of Photoshop in grading invasive risk of gastric stromal tumors (GSTs). Methods EUS image of 97 cases of GSTs confirmed by pathological and immunohistochemical examination were collected. GSTs were divided into four groups (very low risk, low risk, intermediate risk, high risk) by tumor size, mitotic count and rupture of tumor. Mean gray value (intensity of echo) and gray value standard deviation (uniformity of echo) of EUS images of the lesions were determined by Photoshop and then the differences of each group were found by statistical analysis. Results It is difficult to differentiate EUS images of GSTs from each group by visual observation. The mean gray value of EUS image of very low risk group,low risk group, intermediate risk group and high risk group of GSTs respectively were (56.54 ± 6.10), (59.20 ± 7.51), (77.77 ± 10.90) and (83.43 ± 12.47). There was no significant difference between very low risk group and low risk group (P > 0.05). There was no significant difference between intermediate risk group and high risk group (P > 0.05). In addition, the others all had significantly different from that of each group (P < 0.05). The mean gray value standard deviation of EUS image of very low risk group, low risk group, intermediate risk group and high risk group of GSTs respectively were (8.46 ± 2.59), (12.57 ± 5.89), (12.84 ± 4.15) and (16.69 ± 4.69). There was no significant difference between low risk group and intermediate risk group (P > 0.05). In addition, the others all had significantly different from that of each group (P < 0.05). Conclusions The higher risk of GSTs, the higher of echo intensity and the worse of echo uniformity under EUS. Photoshop combined with EUS is helpful for differentiating different risk of GSTs by analyzing mean gray value and gray value standard deviation of the lesions.
