Objective To provide anatomic evidence for the application of the lateral thigh perforator flap.Methods Dissected five fresh Chinese adult lower limbs specimens which were injected with red latex via arterial cannula.On the lateral area of middle and distal thigh,obseved the number,distribution,course,category,length of pedicle and external diameter of the flaps' perforators on specimens.Results On the lateral area of middle and distal thigh 19 perforator arteris were observed in these specimens,averagely there were (3.8 ± 1.3) cutaneous perforators in each flap.Perforators mainly origined from the third perforator artery of profunda femoris,secondly from the second,fourth perforator artery and superior lateral genicular artery.Cutaneous perforators of the third perforator artery of profunda femoris pierced the flap on (13.8 ± 1.5) cm proximal of the fibulae capitulum,while the cutaneous perforators of superior lateral genicular artery on (8.6 ± 1.3) cm proximal of the fibulae capitulum.Averagely internal diameter of cutaneous perforators was (0.7 ± 0.2) mm at the point where the perforators pierced deep fascia.The diameter of the profunda femoris was (1.9 ± 0.2) mm,and the pedicle length was (12.2 ± 0.6)cm.The diameter of superior lateral genicular artery was (1.5 ± 0.2)mm,and the pedicle length was (6.8 ± 1.1) cm.There were inosculated branch in these perforators which came from profunda femoris and superior lateral genicular artery.Conclusion The anatomic characteristic allowed this flap would likely be clinically useful in repairing soft tissue defects in extremity limbs as a free or pedicled flap,which the cutaneous perforators invariably appeared on the skin of lateral areat of middle and distal thigh ; the flap could obtain enough length of the pedicle from its origination ; the vessel has large caliber supporting a substantial cutaneous territory.

Objective To summarize the experience of surgical treatment and to explore the oper-ation method choice of ascending aortic aneurysm caused by Marfan Syndrome. Methods The clinical da-ta of 16 patients from 2005 January to 2011 November were retrospectively analyzed. Results Among all, there was no operative mortality,but 6 cases of early postoperative complications(37. 5%),including 2 ca-ses of arrhythmia,2 cases of pulmonary infection,1 case of renal insufficiency and 1 case of pneumothorax. The follow-up time was 12~63(25 ± 9)months. During follow-up,2 patients died(12. 5%),1 due to rup-tured abdominal aortic aneurysms and 1 due to renal failure. Besides there were 2 cases of anticoagulation complications and 1 case of coronary heart disease. Conclusion Although sparing aortic root replacement of aortic valve has similar curative effect as Bentall operation and avoids the mechanical valve-related com-plications,the indications are relatively strict. Bentall operation is still the first choice for severe patients.

AIM: To explore the regulatory mechanism of nerve growth factor (NGF) on substance P in the experimental asthmatic guinea pig. METHODS: Radioimmunoassay was used to determine the alteration of substance P levels in the lower respiratory tract and visceral sensory afferent sites while NGF was absent (inhalation of NGF antibody through nasal cavity) in the asthmatic guinea pig. RESULTS: The contents of substance P in the trachea, bronchus, lung, C7 - T5 spinal ganglia and the correspondent spinal dorsal horn, nodose ganglia and solitary nucleus area in the experimental asthmatic guinea pig with the absent of NGF in the respiratory tract, were much lower than those in the asthmatic and control groups (P

OBJECTIVE:To prepare the levofloxacin(LEF)thermosensitive gel for ophthalmic drug delivery,and to study the drug release in vitro.METHODS:Poloxamer407was used as themosensitive material for the LEF eye drop,the best con?centration of poloxamer in prescription was selected according to the temperature of gel,a novel membraneless model was used to study the drug release.RESUTS:The detected concentration of LEF was in the linear range of3~11?g/ml(r=0.9991,n=6),the recovery was99.62%;The best concentration of poloxamer in prescription was18%;Drug release followed zero-order kinetics,and the quantity of drug release was controlled by that of gel dissolution.CONCLUSION:The preparation is simple in method and easy to control in dosage,therefore it shows a promising future in development.

AIM: To detect dystrophin expression in skeletal muscles of mdx mice after bone marrow transplantation (BMT), and to evaluate the effect of BMT on Duchenne muscular dystrophy (DMD). METHODS: Bone marrow cells were cultured for three days, and then transplanted into mdx mice irradiated lethally through tail veins. After 4 and 6 months, dystrophin expression on myocytes membranes in mdx mice was detected by fluorescent immunohistochemical staining. The centrally nucleated fibers (CNF) were calculated by HE staining, and the physiologic parameters measured and the motor function detected by traction test, rotating rods test and rotating wheels test were also observed. RESULTS: Until 4 and 6 months after BMT, dystrophin was expressed partly on myocytes membranes in mdx mice, and the ratio of CNF decreased, physiologic functions improved, the motor ability reinforced in treated group. CONCLUSION: After BMT, marrow stem cells settled in injured skeletal muscles and bone marrow, then differentiated into myocytes with dystrophin expression and caused the improvement of pathology, physiology and motor function in treated group finally. These results give a powerful proof for the treatment of DMD with BMT.

AIM: To observe the effects of overload exercise on skeletal muscles in X-linked muscular dystrophy(mdx) mice.METHODS: Mdx mice and C57 mice were carried out swimming and hanging tail movement tests (mdx mice as control did not exercise). It lasted for 13 minutes each time per day, and lasted 3 days. Evans blue was injected into tail vain. The mice were killed the next day, and the hind limbs were taken photographs after skins were flayed. The gastrocnemius muscles and diaphragms cryostat sections were made. Under a fluorescence microscope, Evans blue staining was seen. Then the sections were tested by routine HE staining, the histological change of muscles was analyzed under a light microscope.RESULTS: Many blue colored longitudinal lines were observed in skeletal muscles of mdx mice, whereas they were hardly seen in control mdx and C57 mice. Under a fluorescence microscope, some muscle fibers of mdx mice were stained with Evans blue, few muscle fibers of control mdx mice were stained, and C57 mice were not. Under a light microscope, HE staining of muscles showed some degenerated muscle fibers became round in shape and the myonuclei became condensed, or necrotic fibers had amorphous structures, most of them in the degenerated and necrotic fibers of diaphragms C57 mice did not have these changes.CONCLUSION: Overload exercise did harm to skeletal muscles of mdx mice; Vital staining with Evans blue is useful not only for distinguishing degenerating muscle fibers, but also for studying the degeneration process in dystrophin-deficient muscle.

OBJECTIVE: To study the role of nuclear factor-kappa B (NF-kappaB) and cycloxygenase-2 (COX-2) in the onset of phlegm obstruction due to lung-deficiency in rats and the therapeutic mechanism of Huatan Recipe. METHODS: Twenty-four SD rats were randomly divided into normal group, model group and treatment group, with 8 rats in each group. The rats in the model group and treatment group were exposed to sulfur dioxide and cold wind to establish the rat model of phlegm obstruction due to lung-deficiency, and the rats in the treatment group were also treated with Huatan Recipe, a compound traditional Chinese medicine. The expression of NF-kappaB in the bronchial epithelial cells of the rats was tested with the method of immunohistochemistry, and the COX-2 mRNA in the lung tissues of the rats was measured by using reverse transcription-polymerase chain reaction. RESULTS: The expressions of NF-kappaB and COX-2 mRNA in rats of the model group were higher than those of the normal group (P<0.01), and the expressions of NF-kappaB and COX-2 mRNA in rats of the treatment group were obviously lower than those of the model group (P<0.01). CONCLUSION: The NF-kappaB and COX-2 play an important role in the onset of phlegm obstruction in rats. Huatan Recipe may prevent the development of phlegm obstruction by down-regulating the expressions of NF-kappaB and COX-2 mRNA.
