This review is to provide an overview of current situation and advance of abdominal compartment syndrome. Progress has been made in diagnosis and therapy of abdominal compartment syndrome. At present patients who are diagnosed as abdominal compartment syndrome are associated with a high mortality rate. Therefove, it is important to diagnoze and treat the disease early. Surgical treatment of increased intraabdominal pressure leads in most instances to a rapid and profound correction of the physiological abnormalities. Operative treatment is the unique and effective approach of abdominal compartment syndrome.

Breast cancer stem cells (BCSC)are a class of breast cancer cells that have the capacity of selfrenewal and can differentiate into different cell lineages. These cells, with the ability of high tumorigenesis, invasion and metastasis, play a important role in breast cancer metastasis, recurrence and treatment resistance. The treatments targeting on breast cancer stem cells are very important for improving the efficacy of clinical therapy.

Objective: To explore the effects of ulinastatin on the level of MIF in rats with acute necrotic pancreatitis. Method: 52 healthy Wister rats were randomly divided into three groups: normal control group(group C, 12), ANP group(group A, 20)and UTI group(group U, 20). Severe acute pancreatitis rat model in group A were induced by injection of 315 % sodium taurocholate through retrogradely common biliopancreatic ducts via papilla duodeni. After inducing the rat model of ANP through the way above, rats in group U were treated by ulinastatin through portal vein injection. Pancreas and duodenum were only flipped after opening abdominal cavity in group C. Then rats were killed at 3rd, 6th ,12th ,24th hour after operation respectively. Cut the belly open at once, and draw blood in postcava. The levels of serum MIF were determined with ELISA. Blood amylase was detected through biochemistry instrument. Resected pancreas tissues was scored according to the standard of Kusske. Result: Compared to the normal control group, the level of serum MIF , blood amylase and histopathological scores were significantly increased in ANP group, P

The efficacy of patients infected with hepatitis C virus complicated with cirrhosis is not promising after treated with present standard therapy. With more and more new drugs against hepatitis C virus, many new regimens for the patients with chronic hepatitis C virus complicated with cirrhosis have come forth. Because the adverse reactions of the first generation HCV protease inhibi-tors telaprevir and boceprevir are severe, they are not recommended to be used in the patients with chronic hepatitis C virus complicated with cirrhosis. The other drugs, such as simeprevir, sofosbuvir and ledipasvir show good efficacy in the patients with chronic hepatitis C virus complicated with cirrhosis, however, the sustained virological response ( SVR) in the patients with chronic hepatitis C virus complicated with cirrhosis is lower than that in the patients with chronic hepatitis C virus without cirrhosis. Therefore, the regimens should be optimized in the future to narrow the gap in SVR.

Objective To evaluate the feasibility and its clinical application of 3.0 T MRI in the assessment of the late gadolinium enhancement in patients with cardiac arrhythmias with phase-sensitive inversion recovery (PSIR) single-shot true fast imaging with steady-state precession (True FISP) sequence.Methods Fifty-six patients with arrhythmia confirmed by electrocardiogram underwent MRI in this prospective study.Late gadolinium enhancement were performed with both PSIR single-shot True FISP (sequence 1) and conventional segmented PSIR Turbo FLASH sequences (sequence 2).The overall image quality (4 scales) was assessed and recorded independently by two experienced radiologists.Statistical analysis was performed with Chi-square test and weighted Kappa test.Results Late gadolinium enhancement of all the 56 patients were successfully examined with the sequence 1 and 2.All the image qualities of sequence 1 reached 3 scales or more and met the requirements of clinical diagnosis,and late gadolinium enhancement lesions were detection in 19 patients.All the sequence 2 images were improperly used for clinical diagnosis of the different degrees of artifacts,especially in patients with severe arrhythmia and those who breath-hold with difficulty.Sequence 1 images were classified as scale 4 in 50 cases and scale 3 in 6 cases by Doctor 1,while scale 4 in 48 cases and scale 3 in 8 cases by Doctor 2,respectively.However,sequence 2 images were classified as scale 2 in 15 cases and scale 1 in 41 cases by Doctor 1,as well as scale 2 in 13 cases and scale 1 in 43 cases by Doctor 2,respectively.Sequence 1 image qualities were significantly higher than those of the segmented sequence 2 (x2 values were 141.329 and 141.177,P＜0.01).Excellent agreements between two observers of the 2 sequences (Kappa values were 0.837 and 0.905,P＜ 0.01) were found.Conclusion PSIR single-shot True FISP sequence provides higher reliability for image quality of late gadolinium enhancement in patients with cardiac arrhythmia,which may be useful for clinical application.

BACKGROUND:Breast cancer stem cells not only lead to theoccurrence of breast cancer, but also may cause breast cancer metastasis and recurrence. The relationship between stem cells and cell resistance is also gaining increasing attentions, and the focus on the stem cell treatment may result in unexpected results.OBJECTIVE:To explore the reversal effect of psoralen on glutathione-S-transferase π (GST-π) in human breast cancer MCF-7/ADR cells and its mechanism.METHODS:MCF-7/ADR cells were cultured and enriched in serum-free medium to obtain breast cancer stem cells.RT-PCR and western blot were used to detect the expression of GST-π at the levels of gene and protein in the MCF-7/ADR cells after treatment with 0, 4, 8, 12, 16 mg/L psoralen. To observe the activation of nuclear factor-κB,western blot was used. The expression of GST-π was detected by RT-PCR in 18 μmol/L SN50 group and 8 mg/L psoralen group. Cell counting kit-8 assay was used to detect the effect of doxorubicin on cell proliferation.RESULTS AND CONCLUSION:Compared with the control group, psoralen reduced the expression of GST-π at the mRNA and protein levels, and significantly inhibited the activation of nuclear factor-κB. It was suggested that psoralen could reverse the multidrug resistance of human breast cancer MCF-7/ADR stem cells by decreasing the expression level of GST-π. The mechanism may be achieved by inhibiting the nuclear factor-κB signal pathway.

Objective To explore the effect of psoralen on topoisomerase IIα(TopoIIα) expression of breast cancer stem cells.Methods CD44+CD24-/low breast cancer stem cells were sorted from MCF-7/ADR by magnetic-activated cell sorting(MACS).We observed the growth characteristics of these stem cells through optical microscope and detected the growth-inhibitory effects of psoralen on breast cancer stem cells by CCK-8 assay and IC50 of adriamycin and adriamycin combined with psoralen to calculate the reversal index.The mRNA and protein expressions of Topo IIα were detected using RT-PCR and Western blot, respectively.Results Under the optical microscope, breast cancer stem cells presented spheres.IC10 and IC20 of psoralen on breast cancer stem cells were (6.77±0.23)μg/mL and (10.36±0.21)μg/mL.IC50 of adriamycin and adriamycin combined with psoralen on breast cancer stem cells was (90.03±3.56)μg/mL and (21.47±0.82)μg/mL, the reversal index was 4.19.Psoralen significantly raised the expressions of Topo Ⅱα at mRNA and protein levels.Conclusion Psoralen reversed the resistance of adriamycin by increasing the gene and protein expressions of breast cancer stem cells Topo Ⅱα and the drug targets.

OBJECTIVE To investigate the effect of overexpression of vascular cell adhesion molecule-1(VCAM-1)on the migration in vitro of the murine mesenchymal stem cells(MSCs)and its possible mechanism. METHODS The migration ability of normal mouse MSC (C3) ,empty vector-transfected MSC(C3+N) and VCAM-1 transfected MSC(C3+VCAM-1)was assessed by Transwell culture system in vitro after incubation for 8 and 12 h,respectively. The fetal bovine serum (FBS) was used as the chemotactic agent to induce MSC migration. The transmigrated cells were detected with methylosaniliam chloride(crystal violet)as well as DAPI staining.Furthermore,the specific chemical inhibitors of mitogen-activation protein kinase (MAPK) pathway ( SB203580,PD98059 and JNK inhibitorⅡ)were added to the Transwell system for 12 h and the alteration of the MSC migration ability was evaluated. RESULTS After incubation with FBS for 8 and 12 h,the absolute migrated cell number(7467 ± 485 and 8795 ± 255)and migration rate〔(14.9 ± 1.0)% and(17.6 ± 0.5)%〕of MSC in C3+VCAM-1 group were significantly increased compared with C3 group〔2731±562 and 4779±224, (5.5 ± 1.1)%and(9.6 ± 0.4)%〕and C3+N group〔2539 ± 321 and 5645 ± 1080,(5.1 ± 0.6)%and(11.3 ± 1.1)%〕(P<0.05,P<0.01),but there was no significant difference between C3 and C3+N groups. Moreover,the MSC migration ability of C3+VCAM-1 group was partially suppressed by addition of JNK inhibitorⅡ. The transmigrated cell number(4843 ± 167)and migration rate〔(9.7 ± 0.3)%〕were decreased compared with those of C3+VCAM-1 group without JNK inhibitorⅡ(P<0.01). SB203580 and PD98059,as specific chemical inhibitors of MAPK pathway,had no effect on MSC migration. CONCLUSION VCAM-1 can enhance mouse MSC migration in vitro and th4e mechanism may be related to JNK/MAPK pathway activation.
