Preoperative Computed Tomography Imaging of the Pancreas Identifying Predictive Factors for the Progression of Grade A, or Biochemical Leak, to Grade B Postoperative Pancreatic Fistula Following Pancreaticoduodenectomy: A Retrospective Study.

BACKGROUND This retrospective study aimed to identify the predictive factors for the progression of grade A, or early biochemical leak, to grade B postoperative pancreatic fistula (POPF) following pancreaticoduodenectomy using preoperative computed tomography (CT) imaging of the pancreas. MATERIAL AND METHODS A total of 156 patients were analyzed retrospectively. Biochemical leakage occurred in 60 patients, who were divided into POPF progression and non-POPF progression groups.

An analysis was carried out regarding the relationship between the broken files and canal distribution,degree of curvature of canals, and the relationship between amount of the broken files and the duration was also included.

Periosteal osteosarcoma of the mandible: case report and review of the literature.

Purpose: Periosteal osteosarcoma is an intermediate-grade chondroblastic osteosarcoma, accounting for less than 2% of all osteosarcomas and it occurs extremely rarely in the jaws. We present a rare case of mandibular periosteal osteosarcoma.

Patients And Methods: A 39-year-old man presented with a four months history of a firm swelling of the mental region.

[Connection of trigeminal nerve and facial nerve branches and its clinical significance].

In recent years, many anatomical researches have showed that there are common and extensive connections between the trigeminal nerve and the facial nerve.They are briefly outlined as follows: (1) The infraorbital nerve communicates with buccal branch of the facial nerve. (2) The auriculotemporal nerve of the trigeminal nerve communicates with the buccal, zygomatic,temporal branches and the upper divisions of the facial nerve.

Laparoscopic and open splenectomy and azygoportal disconnection for portal hypertension.

Aim: To compare the outcomes of laparoscopic and open splenectomy and azygoportal devascularization for portal hypertension.

Methods: From June 2006 to March 2009, laparoscopic splenectomy and azygoportal disconnection (LSD) were performed on 28 patients with cirrhosis, bleeding due to portal hypertension, and secondary hypersplenism. Success was achieved in 26 patients.

[The neuromuscular toxicity and clinical application of adriamycin].

Adriamycin (doxorubicin) is commonly used in the treatment of malignant tumours. In recent years,retrograde adriamycin sensory ganglionectomy has been used in treatment of trigeminal neuralgia and has obtained good therapeutic effect. The mechanism of action, particularly, of the toxic effects with different medication methods and choice of doses for muscle cells and nerve cells is still unclear.

[Changes in voltage-gated potassium currents in the trigeminal neurons after a chronic constriction of infraorbital nerve.].

The purpose of this study was to establish a model of trigeminal neuralgia (TN) through an approach from lower edge of cheekbone and to observe the functional changes in the voltage-gated potassium currents in the cultured trigeminal ganglion (TG) neurons. Thirty Sprague-Dawley male rats were divided into two groups, the sham-operated (sham) group and the operated group. The TN model was carried out by using a chronic constriction injury of the infraorbital nerve (ION-CCI) from lower edge of cheekbone.

[The expression and significance of osteopontin and its receptor CD44v6 in oral squamous carcinoma].

Objective: To study the clinical significance of osteopontin (OPN) and its receptor CD44v6 expression in oral squamous cell carcinoma (OSCC).

Methods: OPN and CD44v6 expression were examined in OSCC (n=59) and normal oral mucosa (n=12) by EnVision method, the staining-grade were quantitatively studied by multiple functional image analyzer. Their expression grade of different clinical and pathological index were statistically studied.

[Local drug injection for the treatment of trigeminal neuralgia].

Trigeminal neuralgia is the most common facial pain syndrome,which remains a difficult condition to manage due to lack of knowledge on pathophysiological mechanisms. Local drug injection is a minimally invasive and useful technique to manage trigeminal neuralgia, with a high success rate and low incidence of morbidity. Although a large number of drugs have been used to treat trigeminal neuralgia, there still remains a great challenge to reduce the recurrent rates and complications both intra- or post- injections.

[Evaluation of living donor liver transplantation for patients with hepatocellular carcinoma].

Objective: To evaluate the donor risks and potential recipient benefits of living donor liver transplantation (LDLT) for adult patients with hepatocellular carcinoma (HCC).

Methods: From January 2002 to December 2006, a total of 27 LDLT for HCC patients were performed in our center, of which 25 received right lobe grafts and 2 received dual grafts. The clinical and follow-up data of these 27 recipients and 29 donors were analyzed retrospectively.

Donor safety in adult living donor liver transplantation using the right lobe: single center experience in China.

Aim: To evaluate the safety of donors in adult living donor liver transplantation (LDLT) using the right lobe in a single liver transplantation center in China.

Methods: We investigated retrospectively 52 living donor liver resections performed from October 2003 to July 2006. All patients were evaluated by blood tests and abdominal CT.

[A study of interleukin-10 gene polymorphism in irritable bowel syndrome].

Objective: To investigate whether three diallelic polymorphisms at the position -1082, -819 and -592 in the promoter region of the IL-10 gene were associated with diarrhea-predominant irritable bowel syndrome (D-IBS).

Methods: The IL-10 gene -1082, -819 and -592 position polymorphisms were genotyped by amplification refractory mutation systems-polymerase chain reaction (ARMS-PCR) methods in 43 patients with D-IBS and 41 healthy subjects (HS).

Results: Compared with HS, D-IBS patients had a greater frequency of T/T genotype at IL-10 gene promoter -819 position (67.

[Microvessel density and expression of vascular endothelial growth factor in adenoid cystic carcinoma of salivary gland].

Objective: To discern whether the microvessel density (MVD) and the expression of vascular endothelial growth factor (VEGF) could be prognostic indicators for the metastasis and survival of patients with SACC after radical surgery.

Methods: After the follow-up of 31 primary patients with SACC treated with radical surgeries for at least 60 months, the paraffin-bedded sections of the those patients were stained immunohistochemically with anti-CD34-McAb and anti-VEGF-McAb, respectively. Subsequently, two pathologists double-blindly evaluated the sections stained with anti-CD34-McAb to determine the MVD values individually, as well as, measured the sections stained with the ani-VEGF-McAb to determine the OD values.
