Background and purpose:Nowadays, about therapy of laryngeal carcinoma, people are paying more and more widely attention to ifnding out how to improve quality of patients’ life besides radical surgery. For glottic laryngeal carcinoma which invading anterior commissure or bilateral vocal cord, we performed modiifed frontolateral partial laryngectomy or modiifed cricohyoidoepiglottopexy, and contrastive analyzed the therapeutic efifcacy of the two ways. Methods:Sixty cases patients of glottic laryngeal carcinoma who treated in Hunan Provincial Tumor Hospital during 2005 to 2010, which invaded the anterior commissure or bilateral vocal cord, were randomly attributed to two groups as A and B;30 patients of group A were underwent modiifed frontolateral partial laryngectomy and repaired with bilateral sternohyoid muscle lfap, 30 patients of group B were treated by modiifed cricohyoidoepiglottopexy. Follow-up time of each patient was 5 years postoperation and clinical data were retrospectively analyzed. Results:The 5-year survival rate was 86.7%in group A as well as 83.3%in group B, and there was no statistical difference between two groups (P=0.718). Pronunciation function:22 cases in group A and 21 cases in group B whose pronunciation function can be competent in the noisy environment, and can pronounce“a”and“i”vowel;8 cases in group A and 9 cases in group B can pronounce only a“ha”,“hi”sound, that couldn’t communicate with others in a noisy environment. There was no statistical difference in pronunciation function between the two groups (P=0.774). Incidence of deglutition disorder 4 weeks postoperation:group A was 0 (0/30), group B was 16.7%(5/30), and the difference between the two groups was statistically signiifcant (P=0.026);average time of extubation postoperation:group A was (10±2.3) d, group B was (20±4.6)d, and the difference between the two groups was statistically signiifcant (P=0.0000);recurrence rate of dyspnea after extubation:group A was 16.7%(5/30), group B was 0 (0/30), and there was statistically signiifcant difference between the two groups (P=0.026). Conclusion: For the glottic laryngeal carcinoma which invading anterior commissure or bilateral vocal cord, there was no statistical difference in 5-years survival rate and function of pronunciation between modified frontolateral partial laryngenctomy and modified cricohyoidoepiglottopexy postoperation. The former had less postoperative deglution disorder, earlier extubation time, and to some extent, alleviated the suffering of the patients, but part of these patients needed secondary surgery due to dyspnea which resulted by radioactive tissue adhesion after extubation. The latter had more serious deglution disorder postoperation, longer recovery time, and relatively longer time to extubating, showed no again dyspnea after extubation, and had more extensive adaptation disease. In a word, each way of operation has its advantage respectively.

Background and purpose:The pedicled pectoralis major myocutaneous lfap has been a common choice of tissue lfaps for head and neck reconstruction. Nowadays, with rapid advancement in microsurgery, free lfaps gradually replace the pedicled lfaps. However, not all patients are good candidates for reconstruction surgery using free tissue lfaps. Adjacent pedicled lfaps are safer and more reliable. This paper explores potential application of pedicled pectoralis major myocutaneous flap in reconstruction of complex surgical defects following resection of advanced head and neck malignancies through modification of their preparation and repair method.Methods:Flap design scheme and method of preparation were modiifed to improve the pectoralis major muscle lfap. Fifty-one patients with surgical defects from resection of head and neck malignancies received reconstruction surgery using modiifed pectoralis major muscle lfaps.Results:Modiifed pectoralis major muscle lfaps survived completely in 51 patients. The area of defect regained its shape and appearance after reconstruction surgery. The area of defect obtained excellent functional recovery. Postoperative functional injuries to the donor sites were minimized.Conclusion:Modiifcation in designing and preparing method of the pectoralis major muscle flap improved repair range and distance in reconstruction of complex surgical defect following resection of head and neck malignancies. It also reduced necrosis rate of skin lfaps. Postoperative donor and recipient sites regained their appearance and functions successfully. The pectoralis major muscle lfap is one of the important tissue lfaps used in reconstruction of surgical defect following resection of a head and neck malignancy.

Objective: To investigate the effects of extract of Bulbus Allii Caespitosi on cardiocyte viability of swines with myocardial reperfusion injury by analyzing the 18F-fluorodeoxyglucose ((18)F-FDG) position emission tomography (PET) imaging. Methods: Twenty-four swines were randomly divided into sham-operated group, untreated group, trimethazine group and extract of Bulbus Allii Caespitosi group. Myocardial reperfusion injury was induced by plugging the anterior descending coronary artery of swine with sacculus. Bulbus Allii Caespitosi or trimetazidine was given twice daily for 28 days. Then myocardial perfusion was detected with (18)F-FDG PET/CT and the radioactivity distribution was evaluated. Results: Compared with the untreated group, Bulbus Allii Caespitosi and trimetazidine could improve the activity of myocardial cells after myocardial infarction (P<0.01), and there were no significant differences between Bulbus Allii Caespitosi and trimetazidine (P>0.05). Conclusion: Bulbus Allii Caespitosi can improve myocardial metabolism after ischemia and reperfusion in swines.

BACKGROUND: Researches suggest that transient ischemic attack (TIA)can induce cognitive dysfunction, and cerebral blood flow and its distribution are hypothesized to be closely related to cognitive activities.OBJECTIVE: To investigate the alteration of cognitive function and provide insights into its relations with cerebral perfusion in TIA patients.DESIGN: A case-control study.SETTING: Departments of Geriatrics, Electrophysiology and Magnetic Resonance of Urumqi General Hospital of Lanzhou Military Area Command of Chinese PLA.PARTICIPANTS: Totally 35 male right-handed TIA patients aged 45-78 years with an average of (68.1±8.4) years were selected from the inpatients and outpatients in the Department of Geriatrics, Urumqi General Hospital of Lanzhou Command of Chinese PLA between January 2002 and June 2003. Another 33 healthy right handed male subjects aged 45-77 years with an average of (67.8±8.6) years coming for physical examination were recruited to serve as the control group.METHODS: Patients and control subjects were tested with event-related potentials (ERPs) and the scale of elderly cognitive function (SECF) to examine the orientation, learning and memory, span, recall 1 (association),long-term memory, naming of animals, calculation, classification, copying,language and recall 2 (relation). According to the T score transformation table, the original scores were transformed into T scores relative to the age to eliminate the impact of age, and also into T'score to eliminate the interference by the patients'education, so that cognitive function of the patients could be evaluated with T'score, and the lower the score, the poorer the cognitive function. Cases in the two groups were all tested, and TIA patients were also examined with magnetic resonance angiography (MRA).MAIN OUTCOME MEASURES: Results of ERPs, SECF and MRA.RESULTS: Of the 35 TIA patients and 33 control subjects all completed the trial. Examination of ERPs reveled significantly prolonged latency of P300 components of ERP in the TIA group [(336.2±34.2) ms] than that in the control group [(311.3±44.2) ms, P < 0.05]. The scores of span, recall 1,long-term memory, naming of animals, calculation, and recall 2 in SECF in TIA group were all lower than those in control group (39.7±11.9 vs 47.4±12.0; 54.5±14.8 vs 61.8±14.5; 61.1±7.8 vs 64.7±1.7; 59.4±11.0 vs 64.7±8.8; 50.0±14.7 vs 58.1±14.2; 44.6±15.4 vs 53.2±17.8, t=4.151 0-7.292 8, P < 0.05-0.01). MRA identified abnormalities in 33 of the 35 TIA patients (94%), manifested mainly by stenosis and occlusion involving the vertebral artery (54%, 19/35), bilateral anterior, middle and posterior cerebral arteries (40% ,28/70;59% ,41/70;47% ,33/70), basilar artery (5.71%, 2/35) and bilateral internal carotid artery (5.71%, 4/70) respectively.CONCLUSION: TIA patients are characterized by prolonged P300 latency with multiple cognitive impairments especially in memory and cerebral artery stenosis and occlusion as shown by MRA, suggests that TIA patients have persistent low cerebral perfusion and frequently, cognitive dysfunction in the presence of local blood supply disorder in the hemispheres.
