Objective: To evaluate the efficacy and safety of triplecombination therapy with paclitaxel, cisplatin (intra-abdominal administration) and TS-1 in patients with advanced gastric cancer. Methods: Fifty eligible inpatients with advanced gastric cancer were recruited between January 2008 and January 2011 and treated with triple-combination therapy with paclitaxel (intravenous administration), cisplatin (intra-abdominal administration) and TS-1 (oral administration). The short-term response and adverse reactions were evaluated. The average follow-up time was 11.4 months. The PFS (progression-free survival) and OS (overall survival) were calculated. Results: Of 50 patients, 5 patients achieved complete response and 23 patients achieved partial response, and the objective response rate was 56%. The median PFS was 6.0 months (95% confidence interval: 3.4-8.6 months) and the median OS was 13.0 months (95% confidence interval: 7.9-18.1 months). The major adverse reactions were gastrointestinal reactions, hematologic toxicities and fatigue. Most of these adverse reactions were grades II Grades II adverse reactions were observed in three patients (one had serious vomiting, two had liver dysfunction). The bowel obstruction was relieved after two cycles of chemotherapy in 2 patients who had incomplete bowel obstruction before chemotherapy, and the chemotherapy-associated bowel obstruction after two cycles of chemotherapy occurred in another patient who had no bowel obstruction before chemotherapy. Conclusion: The triple combination therapy with paclitaxel, cisplatin and TS-1 demonstrates benefits in short-term response and the survival for patients with advanced gastric cancer, and it is also well-tolerated. © 2012 by Tumor.

OBJECTIVETo sum up the experience in diagnosis and treatment of Fournier's gangrene and find an optimal evaluation tool for its prognosis by comparing currently used prognostic scoring systems.

METHODSWe retrospectively analyzed 16 cases of Fournier's gangrene diagnosed and surgically treated in our hospital between 2004 and 2012. Using Fournier's Gangrene Severity Index (FGSI), Uludag Fournier's Gangrene Severity Index (UFGSI), Age-Adjusted Charlson Comorbidity Index (ACCI), and Surgical Apgar Score (sAPGAR) , we obtained the prognostic scores of the patients and made comparisons among different scoring systems.

RESULTSFGSI, UFGSI, ACCI, and sAPGAR were all clinically used scoring systems. Statistically significant differences were found in the scores of ACCI and UFGSI but not in those of FGSI and sAPGAR between the death and survival groups, with the maximum area under the ROC curve and minimum standard error for the ACCI score.

CONCLUSIONBoth ACCI and UFGSI are useful for evaluating the prognosis of Fournier's gangrene. However, ACCI is even better for its higher sensitivity and specificity and easier clinical collection.

Objective To investigate the role of microRNA-21(miR-21) on cardiac fibroblast proliferation and dif-ferentiation in the mouse model of myocardial infarction. Methods The mouse model of myocardial infarction (MI) was es-tablished by ligation of the left coronary artery in male C57BL/6 mice(MI group). The echocardiographic assessment and his-tological evaluation were performed after ligation. The expression levels of miR-21 were measured by quantitative real-time PCR in the various myocardial tissues. The cardiac fibroblasts transfected with miR-21 mimic were over-expressed miR-21. The proliferation was assessed by immunostaining for 5-ethynyl-2’-deoxyuridine (EdU). Western blot assay was used to detect the expression ofα-SMA and Smad7 in the cardiac fibroblasts,and compared with control group and blank group. Results The expression of miR-21 was significantly increased in border area in MI group than that of sham group [(6.043 ± 0.231)×10-4 vs(1.620±0.451)×10-4,P<0.01]. There was a higher expression of miR-21 in miR-21 mimic group than that of control group and blank group [(4.839±0.705)×10-4 vs(1.143±0.064)×10-4 vs(1.017±0.201)×10-4,P<0.01]. The EdU positive rate was significantly higher in miR-21 mimic group than that of control group and blank group[(27.892±1.645)%vs(12.553 ± 1.227)% vs(13.946 ± 1.550)%,P<0.01]. The expression of α-SMA was significantly increased in miR-21 mimic group, while the expression of Smad7, a target gene of miR-21, was significantly decreased. Conclusion The over-expression of miR-21 in cardiac fibroblasts disrupts TGF-βsignaling pathway by reducing the expression of Smad7, which promotes the proliferation and differentiation of cardiac fibroblast, and finally regulates cardiac remodeling after myocardial infarction.

Objective To evaluate the value of prenatal ultrasound in the interrupted aortic arch (IAA), and analyze the reasons of misdiagnosis and improve diagnostic ratio of this kind of defects. Methods Ultrasonic characteristics were analyzed in 16 fetuses with aortic arch anomalies, which were compared with ultrasound image and autopsy results of the normal fetus. The relativity of fetal IAA and abnormal chromosome was also analyzed. Results Among the 16 cases, 15 cases were confirmed by anatomy and the accuracy of ultrasound diagnosis was 94% (15/16), of which one case was serious constriction of aortic arch, one case was error type, three cases were obtained explicit type due to unsatisfactory results of prenatal ultrasound. The coincidence rate of ultrasonic type was 73% (11/15). All of the corrected diagnosed cases were detected with ventricular septal, of which 5 cases were detected with complete endocardial cushion defect, 9 cases were found extra cardiac malformations. Among the 7 karyotype check cases, 3 cases were diagnosed with Trisomy 18, 1 case Trisomy 13, while the rest 3 cases normal. The incidence rate of Trisomy 18 was 43 % (3/7). Conclusions Prenatal ultrasound shows a high accuracy in diagnosing fetal interrupted aortic arch (IAA ), but there’s a need to be improved in explicit typing. It is difficult to identify fetal interrupted aortic arch (IAA) and serious constriction of aortic arch (COA). The incidence rate of Trisomy 18 in the abnormal chromosome of fetal IAA is high.

Objective To study the effect of p38 mitogen activated protein kinase (MAPK) pathway inhibitors SB203580 on cell cycle of K562 cell lines and its mechanisms. Methods The expression of mRNA and protein of p38,Cyclin D2,Cyelin E and P27 in K562 cell lines treated with SB203580 were detected by retrotranscription polymerase chain reaction (RT-PCR) and Western blotting, respectively. Cell cycle was determined by flow eytometry (FCM). Results The expressions of mRNA and protein of p38, Cyclin D2 and Cyclin E in K562 cell lines treated with SB203580 were decreased and the expression of p27 was increased.The percentage of cells in G0/G1 phase was increased and was decreased in S phase. There was a significant difference as compared with K562 cell lines before treated with SB203580. Conclusion SB203580 can affect cell cycle regulatory proteins by p38 pathway and eventually inhibit proliferation of K562 cells.

OBJECTIVETo analyzed the relationship between lumbar endplate Modic area changes rate and low back pain by measuring MRI T2 sagittal image of lumbar endplate Modic area changes rate.

METHODSFrom December 2011 to June 2012,70 patients with low back pain in operation were evaluated on pain by VAS and function by JOA,and examined by MRI including 39 males and 31 females with an average age of (51.00 +/- 11.89) years ranging from 29 to 72 years old. Among them, 54 cases had lumbar endplate Modic changes involving 15 cases in types Modic I ,21 cases in type Modic II, 11 cases in type Modic III ,mixed type Modic in 7 cases (eliminated for too few cases). Modic area changes and corresponding vertebral area were measured on MRI T2 median sagittal. The areas of two ways were compared to yield the rate of changes for Modic, for multisegmental Modic changes to calculate the total ratios. A correlation was observed among JOA, VAS and the rate of Modic changes.

RESULTSThe correlation coefficient of change rate of Modic I with JOA score was r = -0.308, P = 0.048 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic I with VAS scores was r = 0.428,P = 0.021 < 0.05, there was a positive correlation. The correlation coefficient of change rate of Modic II with JOA score was r = -0.375, P = 0.043 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic II with VAS score was r = 0.352, P = 0.041 < 0.05, there was a positive correlation. The area change rate of Modic III had no significant correlation with low back pain degree (P > 0.05).

CONCLUSIONModic I and II area changes rate of of patients with low back pain is closely related to the degree of pain low back pain, Modic III area changes rate is not significant correlated to the degree of lower back pain.
