Elevated expression of RUNX3 co-expressing with EZH2 in esophageal cancer patients from India.

BACKGROUND: Runt related transcription factor3 (RUNX3) is considered as a tumor suppressor gene (TSG) that functions through the TGF-ß dependent apoptosis. Promoter methylation of the CpG islands of RUNX3 and overexpression of enhancer of zeste homolog 2 (EZH2) has been suggested to downregulate RUNX3 in cancer. METHODS: Here, we studied the expression of RUNX3 and EZH2 in 58 esophageal tumors along with paired adjacent normal tissue. mRNA levels, protein expressions and cellular localizations of EZH2 and RUNX3 were analyzed using real-time PCR and immunohistochemistry, respectively. DNA methylation was further assessed by the methylation specific-PCR. RESULTS: Compared to normal tissue, a significant increase in expression of RUNX3 mRNA in 31/57 patient's tumor tissue (p < 0.04) was observed. The expression of EZH2 was found to be upregulated compared to normal, and a significant positive correlation between EZH2 and RUNX3 expression was observed (p = 0.002). 22 of the 27 unmethylated cases at the promoter region of the RUNX3 had elevated RUNX3 protein expression (p < 0.001). CONCLUSION: The data presented in this study provide new insights into the biology of RUNX3 and highlights the need to revisit our current understanding of the role of RUNX3 in cancer.

A study on hepatopathic, dyslipidemic and immunogenic properties of fructosylated-HSA-AGE and binding of autoantibodies in sera of obese and overweight patients with fructosylated-HSA-AGE.

Over consumption of fructose may lead to obesity and dyslipidemia and cause fructosylation-induced alterations in the structure and function of proteins. The aim of this study was to investigate the role of fructosylated-HSA-AGE in the pathogenesis of fatty liver (NAFLD and NASH) by biochemical, immunological and histological studies. Immunogenicity of fructosylated-HSA-AGE was probed by inducing antibodies in rabbits. Fructosylated-HSA-AGE was found to be highly immunogenic. Furthermore, fructosylated-HSA-AGE caused mild fibrosis with steatosis and portal inflammation of hepatocytes in experimental animals. Liver function test and dyslipidemic parameters in immunized animals were also found to be raised. Ultrasonography, which should form part of the assessment of chronically raised transaminases, shows fatty infiltration. Interestingly, alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, total cholesterol (TC) and triglyceride (TG) profiles confirms USG images of overweight, obese patients. Thus, present study demonstrates that fructosylated-HSA-AGE is hepatotoxic, immunologically active and may cause dyslipidemia.

Ten-Year Experience of Managing Giant Duodenal Ulcer Perforations with Triple Tube Ostomy at Tertiary Hospital of North India.

Duodenal ulcer perforations have been known since 1600 AD. It is a common surgical emergency and every surgeon will encounter it. The perforation size of >2 cm has been used as the criteria for defining Giant duodenal ulcers. The management of giant duodenal perforations in hemodynamically unstable patient with comorbid condition is taxing because of high incidence of the postoperative leak and mortality. We have used the simple technique of Triple Tube Ostomy after the primary closure of the defect with encouraging results. It is a retrospective study done at the J. N medical college AMU Aligarh from May 2005 to May 2015. Hemodynamically unstable patients who have presented to the emergency with preoperative diagnoses of giant duodenal ulcer perforation and had undergone triple tube ostomy with primary repair of the perforation were included in the study. There were 34 patients of giant duodenal perforation who presented in shock. All of them underwent triple-tube-ostomy after primary repair of the duodenum. Thirty-two patients recovered with two mortalities (5.8 %). Several definite surgical techniques have been described for the management of giant duodenal ulcer perforation but they are complex, have very high morbidity and mortality rate and require an expert surgeon. A close retrospective scrutiny of the patients suggests that simple triple-tube-ostomy technique which is based on the principle of damage control surgery has good postoperative results Therefore, we recommend it as the procedure of choice in these patients.

Intrarenal post-traumatic pseudoaneurysm-USG colour Doppler diagnosis: a case report with review of literature.

Renal artery pseudoaneurysm, although a well-known complication in patients after penetrating trauma or iatrogenic injury, has rarely been described after blunt torso trauma. A 22-year-old man suffered an accident while on a motorcycle. Upon arrival in the Emergency Room, the patient was unconscious, hypotensive and had hematuria. Initial investigations revealed a fractured shaft of the right femur, multiple rib fractures with hemothorax, extradural haematoma on the right side and a laceration in the right kidney. After the evacuation of intracranial bleed, the patient was managed conservatively. The patient recovered well and was discharged on the 15th post-trauma day. The patient was again present in the emergency room after 6 weeks with 1-week history of gross hematuria. Ultrasonography revealed an anechoic lesion in the right kidney with pulsatile flow on colour Doppler. Further investigation with computed tomography renal angiography was done, which confirmed the pseudoaneurysm of a branch of renal artery. The patient was referred to a higher centre where he was successfully managed with selective arterial coil embolisation.
