OBJECTIVETo investigate the role of duodenum in regulation of ghrelin and body mass index (BMI) and the correlation between ghrelin and BMI after subtotal gastrectomy.
METHODSForty-two patients with T(0-1)N(0-1)M(0) gastric cancer were divided into two groups after gastrectomy according to digestive reconstruction pattern, Billroth I group (n=23) and Billroth II group (n=19) respectively. Plasma ghrelin levels were determined by radioimmunoassay (RIA) before and at day 1, 7, 30 and 360 after gastrectomy,and BMIs were also measured.
RESULTSTwo groups had identical postoperative trends in ghrelin alterations during the early stage, both dropping to nadir at day 1 (36.7% vs 35.7%), then markedly increasing at day 7 (51.0% vs 51.1%). At day 30, ghrelin level of Billroth I group was slightly higher than that of Billroth II group. At day 360, ghrelin level of Billroth I group recovered to 93.6%, approaching though lower than preoperative level and no significant difference was displayed, while ghrelin level of Billroth II group recovered only to 81.6% of preoperational level and significant difference existed (P=0.033). Compared with preoperative levels, ghrelin of two groups decreased by 6.9% and 18.4% while BMI by 3.3% and 6.4% respectively, liner regression correlations were revealed in both groups between decrease magnitudes(R(1)(2)=0.297,P=0.00;R(2)(2)=0.559,P<0.001).
CONCLUSIONSAnatomico-physiological duodenum compensatively promotes ghrelin recovery, accordingly enhances BMI after gastrectomy. Regarding patients with insufficient ghrelin secretion, ghrelin is positively correlated with BMI.

OBJECTIVETo investigate how transient low dose of hydroperoxide pretreatment prevents cardiac ischemia/reperfusion injury.
METHODSSD rats were divided into 4 groups: sham operation (Sham), standard ischemia/reperfusion (I/R), ischemic preconditioning (IPC) and IR preceded by low H2O2 treatment. Cardiac function and injury parameter were compared among groups.
RESULTSIPC protected reperfusion injury and improved cardiac function. Low H2O2 treatment played a role in cardioprotection similar to IPC. Low H2O2 was indeed generated in the early phase of simulated ischemia and attenuated cytochrome c release induced by high Ca2+ in isolated mitochondria.
CONCLUSIONLow H2O2 plays a critical role in cardioprotection probably by inhibiting mitochondrial permeability transition.

OBJECTIVETo discuss the characteristics and experience for surgical treatment of combined calcaneal fracture.
METHODSBetween February 2004 and September 2007, 17 feet of 13 patients with combined calcaneal fractures underwent surgical operations. Among 17 calcaneal fractures, 8 combined with ipsilateral talus fractures, 5 combined with trimalleolar fractures, 4 combined with Pilon fractures. Firstly, fractures of hinder foot were treatment with open reduction and internal fixation according to the principle. Of all, 15 fractures were treated with screws or titanic plate plus open reduction and internal fixation, the rest 2 fractures were treated with subtalar arthrodesis. Postoperative X-ray assessed the internal fixation and union of fractures. The foot function was evaluated by the Maryland Foot Score.
RESULTSA total of 13 patients were all followed up for 16.0 - 33.0 months (average 26.5 months), superficial infection was found in a patient with open wound 10 d after surgery. All the bone fractures united after surgery from 4 to 6 months. Morphous improvement of the calcaneal were proved by X-ray films and there here was no plates and screws' breakage, loosening. Mild osteoarthritis in Subtalar and ankle joints were found by X-ray after surgery from 9 months to last follow-up. Cystic degeneration and necrosis were found in 5 and 2 cases of talus fractures respectively. According to Maryland Foot Score, excellent was in 3 feet, good in 6 feet, fare in 5 feet and poor in 3 feet, with excellence rate of 52.9%.
CONCLUSIONSCombined calcaneal is a calcaneus-based concomitant ankle and foot fractures after a high-energy injury. Good deal of soft tissue and correct design of operation pre-operatively, restoration of form and power lines of calcaneal, effective bone graft, right place of simple internal fixation or subtalar arthrodesis and good reduction and internal fixation of other fracture in hinder feet intra-operatively and correct function postoperatively are key points to have a relatively satisfied treating effect of combined calcaneal fractures.

OBJECTIVETo discuss operative methods and effects for Müller-Weiss disease.
METHODSFrom March 2005 to May 2011, 15 patients were operated. There were 2 males and 13 females, with an average age of 51.8 years (range, 26 to 62 years). The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was (42 ± 13) points. According to the Maceira Staging system, 1 foot was grade 2, 6 feet were grade 3, 4 feet were grade 4, and 4 feet were grade 5. The technique consisted of arthrodesis of the talonaviculocuneiform joints with plate, arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint with plate, or triple arthrodesis with screws, according to the preoperative evaluation.
RESULTSTen feet were treated with arthrodesis of the talonaviculocuneiform joints, 3 feet were treated with arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint and 2 feet were treated with triple arthrodesis. Two patients were lost to follow-up. The average follow-up after operation was 19.2 months (range, 9 to 38 months). All feet were solid fusion and the average duration of union was 13.3 weeks (range, 12-16 weeks). The AOFAS ankle-hindfoot score at the last follow-up was (83 ± 6) points. Two feet were excellent, 10 feet were good, and 1 foot was fair. The length of feet was (14.2 ± 1.0) cm before surgery and (15.7 ± 0.9) cm at the last follow-up (t = 11.570, P < 0.05). The Meary's angle was -6.1° ± 13.1°before surgery and 1.1° ± 3.0° at the last follow-up (t = 2.248, P < 0.05). The talocalcaneal angle was 4.5° ± 2.2° before surgery and 18.0° ± 4.0° at the last follow-up (t = 11.700, P < 0.05). One foot had breakage of the plate and screws at arthrorisis of naviculocuneiform joint and none had complications related to the incision.
CONCLUSIONOperations for Müller-Weiss disease, according to concrete conditions using different therapeutic program, may achieve a satisfactory outcome.
