OBJECTIVETo summarize the experience in one-stage urethroplasty with pedicled scrotal skin flap for hypospadias, and improve its therapeutic effect.

METHODSWe retrospectively analyzed the clinical data of 310 cases of hypospadias (except coronal hypospadias) treated by one-stage urethroplasty with pedicled scrotal skin flap. All the patients were followed up for 6 to 24 months.

RESULTSNo postoperative complications were observed except urinary fistula, which occurred in 12.6% of the patients. Postoperative fistula formation was associated with the type of hypospadias, the length of the urethral defect and postoperative comprehensive medication, but not with the stent indwelling time after surgery. Most of the fistulae were located at the base of the penis.

CONCLUSIONOne-stage urethroplasty with pedicled scrotal skin flap is a simple and effective option for all types of hypospadias except the coronal type, and postoperative treatment is very important.

Radiogenomics, an extension of radiomics, explores the relationship between imaging features and underlying gene expression patterns. This field is instrumental in providing reliable imaging surrogates, thus potentially representing an alternative to genetic testing. The rapidly growing area of radiogenomics that utilizes ultrasound (US) imaging seeks to elucidate the connections between US image characteristics and genomic data. In this review, the authors outline the radiogenomics workflow and summarize the applications of US-based radiogenomics. These include the prediction of gene variations, molecular subtypes, and other biological characteristics, as well as the exploration of the relationships between US phenotypes and cancer gene profiles. Although the field faces various challenges, US-based radiogenomics offers promising prospects and avenues for future research.

OBJECTIVETo introduce a new prefabricated flap with matched colour, texture, thin enough thickness, large enough dimension and reliability for reconstruction of massive defect of face and neck.

METHODSThe patients with massive scar of face and neck were selected for treatment with prefabricated flap. Flap prefabrication involved two stages. The "sandwich" structure including the descending branch of the lateral femoral circumflex vessels and surrounding muscle fascia was harvested from the thigh and anastomosed to superior thyroid artery or facial vessels. Flap prefabrication was performed by inserting the fascia flap between the cervicothoracic skin and the tissue expander placed beneath the skin. After a period of expansion, the flap was transferred to the recipient site based on the implanted vessels. The results including complications were examined during follow-up.

RESULTSNine patients received this treatment. The average dimensions of fascia flap harvested was 6.3 cm x 11.2 cm. After mean interval of 16.7 weeks, the expanders were filled to a mean volume of 1670cc. The size of prefabricated flap ranged from 12 cm x 15 cm to 15 cm x 32 cm. In all cases, the flap efficiently covered the entire defect of the face and neck, and the donor site of the flap is closed primarily. All of the flaps developed venous congestion in some degree after the second operation. Partial flap necrosis occurred in two cases. Three flap was thinned to contour the bulky pedicle. During follow-up, the transferred flap was matched well to the adjacent skin. The reconstructed face restored nature contour and expression. Muscle weakness or paraesthesia was not found in the donor thigh.

CONCLUSIONSCervicothoracic Prefabricated Flap, is reliable and versatile in the reconstruction of massive soft tissue deficits with restoration nature surface and expression of the face and neck.

OBJECTIVETo validate the predictive power of the 5th and 6th editions of TNM staging system (TNM-5, TNM-6) in a Chinese patient cohort with hepatocellular carcinoma (HCC) sized > or = 5 cm after radical hepatectomy.

METHODSConsecutive 121 patients with HCC sized > or = 5 cm undergoing radical hepatectomy between January 1995 and December 2002 were included. The impact of clinicopathological variables on prognosis was determined by univariate and multivariate analyses, after excluding 2 perioperative deaths.

RESULTSIn univariate analysis, TNM-5 stage did not show prognostic significance for overall or disease-free survival, as opposed to TNM-6 stage, Edmondson-Steiner grade, portal vein tumor thrombosis (PVTT), vascular invasion, satellite nodule, Child-Pugh grade, and hepatitis B surface antigen (HBsAg) positivity. When these significant variables were entered in multivariate analysis, Edmondson-Steiner grade was the sole independent prognosticator for both overall and disease-free survival, whereas Child-Pugh grade independently influenced disease-free survival. However, TNM-6 stage lost its predictive potential in multivariate analysis.

CONCLUSIONSNeither TNM-5 nor TNM-6 staging system is revealed to be independently prognostic in patients with HCC sized > or = 5 cm after radical hepatectomy. Therefore, TNM-6 calls for more support in many subsets of HCC patients.

OBJECTIVETo investigate the pathophysiological role of CXCL16 in immunological liver injury induced by Bacille de Calmette et Guerin (BCG) and lipopolysaccharides (LPS).

METHODSImmunological liver injury was induced by BCG and LPS in mice, and the expression of CXCL16 was detected in the liver tissues by real-time quantitative PCR and immunohistochemical examination. The relationship of the expression of CXCL16 and the extent of hepatic necrosis was investigated histopathologically and immunohistochemically. Mononuclear cells were isolated from the liver tissues and their numbers were counted; T lymphocytes populations in the liver tissue were also analyzed with FACS.

RESULTSThe immunological liver injury model was successfully created. Up-regulation of CXCL16 in injured livers correlated with the extent of liver injury and the amountmononuclear cell infiltrations.

CONCLUSIONThese findings suggest that up-regulation of CXCL16 was closely correlated with liver injury extent during the immunological liver injury induced by BCG-LPS in mice, and intrahepatic recruitment of specific lymphocytes might be an important mechanism of liver injury.

OBJECTIVE: To summarize the mononostril-septum-transsphenoidal approach for pituitary adenoma. METHODS: The clinical features, operative techniques, and outcome of 36 patients with pituitary adenoma were analyzed retrospectively. RESULTS: Tumors were totally removed in 28 cases, and subtotally resected in 8 patients. No patient died after the operation. Endocrine symptom of 31 patients returned to the normal level, the symptom of the other 5 cases were improved. Thirty patients with visual field defects recovered after the operation. Cerebrospinal fluid leakage occurred in one patient, and was cured with conservative treatment in 2 weeks. CONCLUSION Mononostril-septum-transsphenoidal approach can make use of the natural space of the nasal cavity, which has many advantages, such as direct approach, short operative time, minimal invasion, and few complications. It is a effective transsphenoidal surgical approach.
