Objective To explore the design of forehead flap pedicled with supratrochlear artery and shift way for aesthetic reconstruction of the nose without secondary operations for debulking.Methods Origin of blood supplies and the distributed situation of the vessel in the frontal region were studied through the internal carotid artery and the external carotid artery X-ray angiography.The frontal region existed polyphyletic blood supplies,the supratrochlear artery and the supraorbital artery set out many branches,respectively,in the level of frontal bone eyebrow plane.One constant,thicker horizontal branch from the superficial temporal artery obviously extended to the forehead median.The branches from three blood vessels mentioned above constituted the network of artery adequate in the muscle and the subcutaneous tissue level,assumed the three-dimensional distribution in the forchead region.The nasal reconstruction had been done for 9 patients with the oblique orientation designed forehead flap by using one side of supratrochlear artery as the pedicle and cutting skin paddle with the same or the opposite side of forehead flap.Results All flap survived completely with the restoration of nasal shape and functional satisfaction.Conclusion The forehead oblique orientation flap pedicled with one side supratrochlear artery is nourished by the rich blood supply.The flap can be split into two flaps:a myofascial flap and a skin flap in far part.Myofascial flap may be the good package of cartilage framework,and simultaneously split skin flap is favorable of the shape models.The flap may satisfy the demand of the nasal restoration.

Objective The purpose of this study was to determine how to preserve the remaining pancreatic body and tail in the pancreatectomy. Methods In seven cases of pancreatectomy, three of them were the rupture of pancreatojejunal anastomosis, and four of them were the pancreatectomy for tumor in the pancreatic neck or body. During operations, a bridge internal drainages was used to drain the pancreatic juice into the adjacent jejunum. After the operations, the supportive treatment, continuous irrigation of peritoneal cavity and pancreatic enzyme inhibition were used. Results In all seven patients, the remaining pancreatic body and tail were successfully preserved. The endocrine functions of these patients recovered to nearly normal level and patients were discharged. Conclusions In preserving the remaining pancreatic body or tail, the bridge internal drainage has its advantage of convenience. It effectively preserves the exocrine of pancreas as well as its endocrine

OBJECTIVETo investigate the prevalence of thyroid diseases in a community which did not use iodized salt.

METHODSThe survey was conducted in Panshan, Liaoning Province. 1 103 inhabitants aged 14 years or more attended the examinations, which included questionnaire, physical examination and serum analysis. Iodine in the urine and thyroid B ultrasound examination were also conducted.

RESULTSThe prevalence of overt hyperthyroidism and hypothyroidism was 16.3 per thousand and 2.7 per thousand, respectively. Subclinical hyperthyroidism and hypothyroidism were detected in 37.2 per thousand and 9.1 per thousand of the subjects, respectively. Serum autoantibodies to thyroid were detected in 10.9% of the entire population. The prevalence of goiter was 20.7% (diffuse goiter 16.8% and nodular goiter 3.9%).

CONCLUSIONIn the iodine deficient areas, perhaps autoimmununization is not only related to the development of goiter but is also the main cause of subclinical hyperthyroidism and hypothyroidism.

OBJECTIVETo assess the value of magnetic resonance (MR) myocardial perfusion imaging (MRMPI) in evaluating the myocardial viability in patients with myocardial infarction.

METHODSMRMPI was performed in 51 patients with myocardial infarction using a 1.5 T MR scanner. All the patients were examined using IR-turbo FLASH sequence during the first-pass and delayed phase 5-30 min after injection of 0.1 mmol/kg Gd-DTPA at the rate of 4 ml/s. The short axis images were acquired during the first-pass, and both the short axis and long axis images were obtained during the delayed phase. The left ventricular wall on the short-axis slice was divided into 8 segments. A correlative study of the results of the rest and stress (99m)Tc single photon emission computed tomography (SPECT) was carried out in 21 patients.

RESULTSIn the 51 patients with myocardial infarction, 42(82.3%) showed hypoperfusion during the first-pass imaging and 50(98%) had delayed hyperenhancement. In the 21 patients receiving SPECT, 48 nonviable segments was detected among the 168 segments scanned by (99m)TcSPECT, and MRMPI showed delayed hyperenhancement in all the infracted areas. Of the 120 viable segments detected by rest and stress (99m)Tc SPECT, 97 segments (80.8%) were found to be free of delayed hyperenhancement by MRMPI. With the rest and stress (99m)Tc SPECT as the reference, the sensitivity and the specificity of MRMPI were 100.0% and 80.8%, respectively.

CONCLUSIONMRMPI allows effective identification of the myocardial viability and nonviability as well as the severity and extent of the myocardial infraction.
