OBJECTIVE: Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder. METHODS: We treated three patients with post-traumatic ventricular septal defects caused by stab wounds with knives. After the heart wound was repaired, patient examinations revealed ventricular septal defects with pulmonary/systemic flow ratios (Qp/Qs) of over 1.7. The post-traumatic ventricular septal defects were closed percutaneously with a patent ductus arteriosus occluder (Lifetech Scientific (Shenzhen) Co., LTD, Guangdong, China) utilizing standard techniques. RESULTS: Post-operative transthoracic echocardiography revealed no residual left-to-right shunt and indicated normal ventricular function. In addition, 320-slice computerized tomography showed that the occluder was well placed and exhibited normal morphology. CONCLUSION: Our experiences indicate that closure of a post-traumatic ventricular septal defect using a patent ductus arteriosus occluder is feasible, safe, and effective. © 2012 CLINICS.

SIRT1 is the homologue of sir2 in mammals, which is a nicotinamide adenine dinucleotide (NAD(+)) dependent histone deacetylase. SIRT1 is involved in many physiological processes, such as metabolism, senescence, inflammatory response, neuroprotection, and tumorigenesis by acetylating histones and multiple transcription factors. However, the exact role of SIRT1 in tumor is still under controversial. Immunohistochemistry and Western blot were performed to investigate the expressions and subcellular localizations of SIRT1 and Phospho-SIRT1 in colorectal cancer tissues and adjacent normal tissues. The relationship between SIRT1 or Phospho-SIRT1 and clinicopathological characteristics was also analyzed. Real-Time PCR was performed to investigate the transcriptional level of SIRT1 mRNA in colorectal cancer tissues and adjacent normal tissues. SIRT1 and Phospho-SIRT1 were both localized in the nucleus. The expressions of SIRT1 and Phospho-SIRT1 were higher in colorectal cancer tissues than normal tissues. SIRT1 expression in cancer tissues was associated with patient age, TNM stage and mutant P53 loss. Phospho-SIRT1 expression in cancer tissues was associated with Ki67. SIRT1 and Phospho-SIRT1 were highly correlated in cancer tissues and normal tissues. The ratios of Phospho-SIRT1 and SIRT1 expression in cancer tissues were higher than normal tissues. SIRT1 mRNA level was no significant difference in cancer tissues and normal tissues. SIRT1 have a dual character in colorectal cancer, and Phospho-SIRT1 may determine the role of SIRT1 in colorectal cancer formation.

The prognostic value of the HPV status in ESCC is much controversial, this study aimed to determine the prognostic importance of high-risk HPV and p16 in patients with ESCC. A total of 105 consecutive patients who underwent esophagectomy in 2008 were included in this study. All specimens with ESCC were tested by in situ hybridization for HPV16/18 and immunohistochemistry for p16 expression. Kappa values were calculated using Cohens kappa test. The 5-year overall survival (OS) and progression-free survival (PFS) were calculated in relation to the two markers and the Cox proportional hazards model was used to determine the hazard ratio (HR) of variables. Thirty-nine (37.1%) of 105 were p16-positive, and HPV was detected in 29 of the 105 patients (27.6%) with ESCC. P16 was detected in 25 of the 29 patients (86.2%) who were HPV-positive, and only 14 of 76 patients (18.4%) who were HPV-negative (P < 0.001). Cohens kappa coefficient revealed an agreement in two researchers (kappa = 0.61). The 5-year OS rate and PFS rate in the p16-positive group were 64.1% and 58.7%, respectively, and the rates in the p16-negative group were 45.5%, 37.9%, respectively. The difference of survival rate between the two groups remained statistically significant. P16-positive patients had better 5-year rates of OS and PFS than p16-negative group (P = 0.02 and P = 0.007 by the Log-rank test, respectively). Using HPV status as a stratification factor, we found differences in OS and PFS that were consistent with those based on p16 expression. P16 is a very good marker of HPV infection for ESCC. HPV-positive or p16-positive ESCC is a distinct entity with a favorable prognosis compared with HPV-negative or p16-negative ESCC.

To explore the effects of a new management model of comprehensive treatments of acute spinal cord injury (SCI) on clinical application.From January 2010 to January 2011, there were 89 patients with acute SCI over the same admission period, including 32 cases divided into the management model group and the other 57 into the control group. Respectively, at the 1, 3 and 6 months after treatment, the score standardization, developed by the American Association of spinal cord injury (ASIA), was used to assess the motor and sensory function during the admission period. At the same time, a follow-up survey was made to investigate the satisfaction of patients and their families.At 1 and 3 months after treatment, the motor and feeling function scores of patients in the experimental group both improved significantly compared with the control group, and the differences were statistically significant (P<0.05). In addition, six months after treatment, the motor and sensory function scores of patients in the control group were not significantly improved any longer; while those scores in the experimental group still significantly recovered, and the difference between experimental and control groups was also statistically significant (P<0.05). According to the follow-up, patients and their families in the experimental group were of greater satisfaction than the control group (P<0.05).The management model of acute SCI treatment performed perfect clinical effects, and was worth promoting.
