BACKGROUND
Intramural esophageal bronchogenic cyst is very rare. Surgical removal of the cysts is advised even the patients are asymptomatic, since the cyst can lead to complications, and there is a risk of malignant transformation. Thoracotomy or thoracoscopy is the most commonly used approach for complete excision of the cysts. To our knowledge, this is the first report to excise intramural esophageal bronchogenic cyst completely by endoscopic submucosal tunnel dissection (ESTD).
CASE PRESENTATION
A 40-year-old male was referred to our hospital due to the detection of a submucosal tumor at the distal esophagus. The tumor was found during gastroendoscopy in a general health check-up. The patient had no symptoms. A benign esophageal tumor was confirmed by endoscopic ultrasonography (EUS) and computed tomography (CT). On the basis of these results, ESTD was performed. During the procedure, a cystic mass was observed between the mucosa and the muscular layers of the esophagus, and a hybrid knife was used for dissection. Histopathological examination showed the cyst wall was lined by pseudostratified ciliated columnar epithelium, consistent with a bronchogenic cyst. The esophagography using meglumine diatrizoate showed no leakage on the seventh day after ESTD. The patient remained asymptomatic and had a regular diet during the follow-up period.
DISCUSSION AND CONCLUSIONS
We successfully utilized ESTD for complete removal of esophageal bronchogenic cysts originating from the muscularis propria. The approach appeared safe, providing a minimally invasive treatment option for patients.

Specific anatomy and radiographic illustration of the digestive tract and transit time of two orally administered contrast media in Inland bearded dragons (Pogona vitticeps).
The aim of this study was to describe the specific gross and radiographic anatomy of the digestive tract of inland bearded dragons (Pogona vitticeps). Eleven bearded dragon cadavers of both sexes (6 females, 5 males) were dissected to examine, measure, and document the specific gross anatomy of the alimentary canal. Measurements collected from the cadavers included snout-vent length, total length of the alimentary canal, and the lengths of the individual sections of the gastrointestinal tract, including the esophagus, stomach, small intestine, ampulla coli, isthmus coli, rectum, and the distance from the coprodeum to the vent opening. Twenty-two healthy adult bearded dragons (13 females, 9 males) maintained under standardized husbandry conditions underwent a physical examination, blood collection, and whole-body dorsoventral and lateral survey radiographs; these animals were used to provide the radiographic images of the complete digestive tract. For the subsequent contrast passage studies, two different contrast media, barium sulfate (BaSO4, Barilux suspension) and an iodinated ionic radiocontrast agent (Sodium meglumine amidotrizoate [SMAT], Gastrografin), were used. Water-diluted Barilux suspension (dose 9 ml/kg) was administered orally to 5 bearded dragons, while Gastrografin (dose 5ml/kg) was administered orally to 21 bearded dragons. Four animals were used for both contrast media studies, but received a break of four weeks in between. Dorsoventral and laterolateral radiographs were collected at 0 (baseline), 15, 30, and 45 minutes and 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 30, and 36 hours after each contrast medium was administered. Both contrast media were found to illustrate the alimentary tracts in the adult bearded dragons. Transit time was substantially faster with SMAT, and SMAT illustrated the entire gastrointestinal tract within 36 hours; BaSO4 did not fully illustrate the gastrointestinal tract in 36 hours. These results might serve as a guideline for the interpretation of subsequent contrast studies in this lizard species.

OBJECTIVE
To observe the effect of acupuncture and moxibustion on renal Fas and Fas ligand (FasL) expression in contrast-induced nephropathy (CIN) diabetic rats, so as to explore its protective mechanisms.
METHODS
A total of 40 diabetic male SD rats were randomly divided into control, model, acupuncture, moxibustion and combined treatment (acupuncture combined with moxibustion) groups (=8 rats in each group). The diabetic model was established by i.p. injection of Streptozotocin (60 mg/kg), followed by regular raising for 9 weeks. Then, the manual acupuncture, moxibustion or acupuncture plus moxibustion at "Sanyinjiao"(SP6) "Shenshu"(BL23) and "Pishu"(BL20) was given to the diabetic rats, once daily for 7 days. On the 8th day, these diabetic rats received i.p. injection of compound Meglumine Diatrizoate Injection (10 mL/kg) for establishing CIN model. Then, the venous blood specimens were collected for detecting contents of serum urine nitrogen (BUN, with urease method) and creatinine (Scr, with picric acid method). The kindey tissues were exteriorized for detecting nitricoxide synthase (NOS, with oxidation-reduction method), malondialdehyde (MDA, with thiobarbituric acid method), superoxide dismutase (SOD, with xanthine oxidase technique) and total antioxidant capacity (T-AOC, with colorimetric technique). The expression levels of Fas and FasL in the kidney tissues were detected by quantitative real-time PCR and Western blot separately. The histopathological and ultrastructural changes of the kidney were observed under microscope (after H.E. staining) and transmission electron microscope, respectively.
RESULTS
Following modeling and compared with the control group, the BUN, Scr and renal MDA contents, and Fas and FasL mRNA and protein expression levels were significantly increased (<0.01, <0.05), and renal NOS, SOD and T-AOC levels considerably decreased in the model group (<0.05). After the interventions and compared with the model group, serum BUN and Scr contents and renal Fas mRNA and protein expression levels in both acupuncture group and combined treatment group, BUN in the moxibustion group, and renal MDA content and FasL mRNA and protein expression levels in the 3 treatment groups were obviously down-regulated (<0.05,<0.01), while renal NOS in the 3 treatment groups, and SOD and T-AOC levels in the combined treatment group were considerably up-regulated (<0.01,<0.05). The effects of the combined treatment were significantly superior to those of simple acupuncure and simple moxibustion in down-regulating serum BUN contents, and Fas and FasL mRNA and protein expression levels, and in up-regulating renal NOS, SOD and T-AOC activity (<0.05). No significant differences were found between the acupuncture and moxibustion groups in down-regulating serum BUN, Scr and renal MDA contents, and Fas and FasL mRNA and protein levels, as well as in up-regulating NOS content (>0.05). H.E. staining showed lobular changes of glomeruli, many local necrosis and vascular degeneration in the model group, and transmission electron microscope displayed thickened basement membrane of the glomerular blood loop, many vacuoles in the cytoplasm of renal tubular epithelial cells, severely swollen mitochondria with disordered, broken or disappeared cristae, and some apoptotic cells in the model group, which were relatively milder in the combined treatment group.
CONCLUSION
Joint application of acupuncture and moxibustion can reduce the oxidative stress and renal injury in CIN diabetic rats, which may be associated with its function in down-regulating the expression of renal Fas and FasL genes and proteins. Acupuncture and moxibustion has a synergistic effect.

Contrast media (meglumine diatrizoate) aggravates renal inflammation, oxidative DNA damage and apoptosis in diabetic rats which is restored by sulforaphane through Nrf2/HO-1 reactivation.
Diabetes mellitus is an independent risk factor for renal impairment in patients exposed to contrast media. It doubles the risk and decreases survival rate of contrast induced nephropathy (CIN). Sulforaphane has antioxidant properties via Nrf2 activation. The interaction of diabetes and/or sulforaphane with contrast media on Nrf2 regulation is not yet understood. Herein, diabetes was induced by a single intra-peritoneal injection of streptozotocin. Animals were then divided into five groups; control non-diabetic group; diabetic group; diabetic/sulforaphane group; diabetic/CIN group; diabetic/CIN/sulforaphane group. Animals were assessed 24 h after CIN induction. Sulforaphane improved the impaired nephrotoxicity parameters, histopathological features, and oxidative stress markers induced by contrast media (meglumine diatrizoate) in diabetic rats. Immunofluorescence detection revealed increased Nrf2 expression in kidney sections after sulforaphane pretreatment. Moreover, gene expression of Nrf2 and HO-1 were up-regulated, while IL-6 and caspase3 were down-regulated in kidney tissues of animals pretreated with sulforaphane. In NRK-52E cells, sulforaphane pretreatment significantly ameliorated the cytotoxicity of meglumine diatrizoate. However, silencing Nrf2 using small interfering RNA (siRNA) abolished the cytoprotective effects of sulforaphane. Collectively, the results of this study suggest that Nrf2/HO-1 pathway has a protective role against CIN and support the clinical implication of Nrf2 activators, such as sulforaphane, in CIN particularly in diabetic patients.

PURPOSE
Routine low dose non-contrast CT of the abdomen and pelvis has been suggested prior to same day completion CT colonography (CTC) to assess for occult perforation at preceding incomplete colonoscopy, before further gaseous insufflation at CTC. The aim of our study is to examine the incidence of clinically significant perforation at low dose CT. We also examine the benefits of low dose pre-scan in assessing adequacy of bowel preparation and identifying any other relevant contraindications to CT colonography.
MATERIALS AND METHODS
We conducted a retrospective review of all low dose non-contrast CTs performed following failed colonoscopies over a 4-year period (n = 392). We also assessed the adequacy of bowel preparation on a scale of 1-5, in order of increasingly adequate preparation. Incidentally noted bowel pathology and contraindications to CT colonography were also recorded.
RESULTS
No perforation was identified either prospectively or in the course of our retrospective review. However, 15 patients (3.8%) were found to have potential contraindications to CT colonography, including: acute diverticulitis, acute colitis, and poor bowel preparation. Overall, the bowel preparation was felt to be adequate (≥ 3) in 86% percent of patients. Two patients (0.5%) identified prospectively had their CT colonography postponed due to poor bowel preparation.
