1.Status and future of metabolic surgery in China
Chinese Journal of Diabetes 2015;(9):773-775
[Summary] With the rapid development of economy ,obesity and type 2 diabetes (T2DM ) have become a serious social problem in China. Metabolic surgery was started to carry out in late 20th century in our country . Currently ,there were many deficiencies in the selection of operation indication ,surgical pattern and procedure ,prevention and treatment of complications ,perioperative management and postoperative follow‐up. Therefore ,to standardize nationwide surgical treatment of obesity and diabetes ,to reduce the incidence of postoperative complications ,Chinese Society for Metabolic & Bariatric Surgery (CSMBS) ,surgeon branch of Chinese Medical Doctor Association called domestic famous experts together to jointly draft a practical manual :Guide to Surgical Treatment of Obesity and Type 2 Diabetes in China (2014). With the spread of this guide ,the number of metabolic surgery increased significantly ,the procedure and management of surgery were further standardized.

Objective To explore a surgical procedure of reduction mammary plasty to assure the viability and sensory of the nipple-areolar complex (NAC) after transposition and to keep the lactiferous function partly. Methods Reduction was accomplished by using perforating vascular branches from the pectoralis major muscle and its fascia supplying the nipple and breast parenchyma instead of the subdermal plexus. The central vascular pedicle supplying the nipple-areola complex was preserved. And the sensory nerve of the NAC was not injured. The erection of the nipple could be observed in operation. Lactation was possible because of preservation of the lactiferous ducts. The technique had been used in 17 patients since 1996. Results The nipple-areola complex was safely transposed with great freedom, and the amount of resection was accurately adjusted for symmetry. No cases of nipple-areola complex sensory change occurred postoperatively in all 17 patients. Breast-feeding was possible at least in one patient after operation. Conclusion This method is ideal for the patients, which keeps the viability and sensory of the nipple-areolar complex and the function of lactation. In another case, the amount of resection is easily adjusted for symmetry.

OBJECTIVEWe used functional magnetic resonance imaging (fMRI) to explore the effects of noxious coldness and non-noxious warmth on the magnitude of cerebral cortex activation during intraoral stimulation with water.
METHODSSix male and female subjects were subjected to whole-brain fMRI during the phasic delivery of non-noxious hot (23 °C) and no- xious cold (4 °C) water intraoral stimulation. A block-design blood oxygenation level-dependent fMRI scan covering the entire brain was also carried out.
RESULTSThe activated cortical areas were as follows: left pre-/post-central gyrus, insula/operculum, anterior cingulate cortex (ACC), orbital frontal cortex (OFC), midbrain red nucleus, and thalamus. The activated cortical areas under cold condition were as follows: left occipital lobe, premotor cortex/Brodmann area (BA) 6, right motor language area BA44, lingual gyrus, parietal lobule (BA7, 40), and primary somatosensory cortex S I. Comparisons of the regional cerebral blood flow response magnitude were made among stereotactically concordant brain regions that showed significant responses under the two conditions of this study. Compared with non-noxious warmth, more regions were activated in noxious coldness, and the magnitude of activation in areas produced after non-noxious warm stimulation significantly increased. However, ACC only significantly increased the magnitude of activation under noxious coldness stimulation.
CONCLUSIONResults suggested that a similar network of regions was activated common to the perception of pain and no-pain produced by either non-noxious warmth or noxious coldness stimulation. Non-noxious warmth also activated more brain regions and significantly increased the response magnitude of cerebral-cortex activation compared with noxious coldness. Noxious coldness stimulation further significantly increased the magnitude of activation in ACC areas compared with noxious warmth.

Objective To investigate the advantages of the external fixators used in the treatment of pelvic fracture. Methods From April 2002 to July 2008, 55 patients with unstable pelvic fracture were treated respectively with simple external fixators, external fixators plus traction and external fixators plus in-ternul fixation according to their different Tile classifications. Results Of this group, 51 cases were followed up for an average of 11 months, 2 cases died because of multi-injuries, and 2 cases were lost in the follow-up. All of the 51 patients obtained bony union. On average, it took 11 (6 to 14) weeks to achieve weight-bearing walking, and 12 (8 to 14) weeks to remove the external fixators for the patients. By Liu Li-ming's evaluation system, the good to excellent rate was up to 88.2%. Conclusions The pelvic fractures of Tile B1 and B2 can be treated with simple external fixators and those of Tile C with external fix-ators plus internal fixation or traction to achieve fracture reduction and stability of the pelvic ring. For the patients with multi-injuries, external fixators used in the emergency treatment can stabilize the pelvic ring, reduce blood loss and improve the success rate.
