ObjectiveTo probe into the clinical efficiency of reconstruction to person who had composite tissue defect of the floor of mouth and the lower part of face with the free forearm flap and free iliac bone in the same term.MethodsBefore the surgery, the surgeon should carefully evaluate the scope and shape of defects in 11 cases who had the composite tissue defects of the floor of mouth and the lower part of face, to design the individual forearm flap, so that it matches with the defect region. During surgery, the first resumption of defects using titanium plates forming the basic shape of mandible and the occlusal relationship,then used to re-sawing to take modeling of the iliac bone,transplanted free iliac bone and fixed after the inside of the titanium plate, thereby restoring the continuity of mandible missing.ResultsFree forearm flap and free iliac bone all survived in 11 cases, the success rate of 100％. The patients were followed up for 6 to 12 months, although the shape of restoration areas were different levels of fat, but eating, swallowing and other oral function had been well improved, 7/11 could enter normal diet, 4/11 to enter liquid diet, At the same time, the patients in social activities can communicate in a language daily, sensory function of skin flap and facial appearance has been satisfactory recovery.ConclusionConformal free forearm flap and free iliac bone is an ideal way to reconstruct the composite tissue defects of the floor of mouth and the lower part of face in the same period, not only safe, practical prognostic effect, and also can significantly improve the patients quality of life, which is worthy of reference and use.

Objective To investigate certain risk factors for postoperative atrial fibrillation (AF) in elderly patients with coronary heart disease after off-pump coronary artery bypass grafting (OPCAB)surgery in order to provide a basis for the prevention and treatment of AF after OPCAB.Methods A total of 139 elderly patients with coronary heart disease who had undergone OPCAB surgery in our hospital were collected as research subjects and divided into the AF group and the nonAF group according to the occurrence of AF after operation.The patients' general information and clinical data were retrospectively analyzed.Risk factors for AF after OPCAB surgery in elderly patients with coronary heart disease were investigated.Results The incidence of AF after OPCAB was 15.8％ in elderly patients with coronary heart disease.There were no statistical differences in gender,history of diabetes,history of myocardial infarction,preoperative β-blocker usage,number of coronary artery lesions,or operation time between the AF group and the non-AF group (P＞0.05).The percentage of patients who were of older age (t=9.960) or had a left ventricular ejection fraction ≥40％ (x2=4.942),a left atrial diameter ≥40 mm (x2 =4.491),a history of hypertension (x2 =12.357),dopamine medication after operation (x2 =8.511),or a bypass vessel count≥ 3 (x2 =5.385) was higher in the AF group than in the non-AF group (all P＜0.05).Logistic regression analysis showed that age,history of hypertension,dopamine medication after operation,left atrial diameter and bypass vessel count were the risk factors for AF after OPCAB surgery in elderly patients with coronary heart disease (OR 3.080,2.435,2.465,3.593,and 1.921,respectively,P＜0.05 for all).Conclusions The incidence of AF after OPCAB is high in elderly patients with coronary heart disease and is affected by many risk factors.These risk factors should be assessed before surgery so that appropriate prevention measures can be taken.

OBJECTIVE: To make an animal model of cervical spondylosis (arthralgia syndrome type) with stimulation of wind, cold, and dampness. METHODS: Twenty-four 8 months old male New Zealand white rabbits were randomly allocated into four groups: normal control group, light stimulation group, moderate stimulation group and severe stimulation group. The wind speed was 10.8-13.8 m/s, the temperature was (5+/-0.5)degrees centigrade, and the humidity was 100%. The rabbits of light, moderate, and severe stimulation groups were kept in the above-mentioned environments for 4 hours everyday, and for a total of 32, 64, and 128 hours, respectively. The intervertebral discs were stained with HE method, and observed with a light microscope. Prostaglandin E(2) (PGE(2)), 6-ketone-prostaglandin F1alpha (6-K-PGF(1alpha)) and thromboxane B(2) (TXB(2)) contents were measured by ELISA. Fas and Bcl-2 expressions were examined by immunohistochemical avidin-biotin peroxidose complex technique. Interleukin-1beta (IL-1beta), tumor necrosis factor alpha (TNF-alpha), and transforming growth factor beta (TGF-beta) mRNA expressions were examined by reverse transcription-polymerase chain reaction. RESULTS: The nucleus pulposus of rabbits in the light and moderate stimulation groups shrunken, and in the severe stimulation group, the anulus fibrosus loosed or ruptured, and the cartilage end-plate became proliferated. Compared with rabbits in the normal control group, the PGE(2) content rose in the light stimulation group, the contents of PGE(2), 6-K-PGF(1alpha), and TXB(2) increased, the expressions of IL-1beta and TNF-alpha mRNAs and Fas were up-regulated, and the expressions of TGF-beta mRNA and Bcl-2 were down-regulated in the moderate and severe stimulation groups. The expression of Fas was up-regulated mostly and Bcl-2 was down-regulated mostly in the severe group. CONCLUSION: Moderate and severe stimulations of wind, cold and dampness can lead to degeneration of cervical intervertebral discs of rabbits. The model corresponds to the theory of traditional Chinese medicine about arthralgia syndrome caused by wind, cold and dampness.
