BACKGROUND:How to effectively improve the airway management and improve oxygen supply at the same time through a simple and effective method becomes an operation key for physicians in fiberoptic bronchoscopy. OBJECTIVE:To observe the clinical effect of self-made simple masks in painless fiberoptic bronchoscopy. METHODS:A total of 60 patients receiving painless fiberoptic bronchoscopy, 32 males and 28 females, with a mean age of (57.8±10.9) years were randomized into two groups: test group with self-made simple mask during painless fiberoptic bronchoscopy and control group with laryngeal mask. In the course of examination, the changes of oxygen saturation, mean arterial pressure and heart rate were observed at different time points. And adverse events of both groups were also recorded. RESULTS AND CONCLUSION:Patients from both groups successfuly completed fibre bronchoscopy. The oxygen saturation, mean arterial pressure and heart rate in the two groups were not significantly different (P > 0.05). However, the test group (one case of bucking) was superior to the control group (seven cases of sore throat) in terms of adverse events (P < 0.05). The simple mask can improve the oxygen supply and reduce the adverse events.

Objective: To study the architectural features and the biomechanical properties of human masseter and temporolis muscles. Methods: The architecture parameters of masseter and temporolis muscles on both sides of 5 human corpes fixed in formalin for more than 1 year were measured and quantitatively analyzed. Results: Human masseter and temporolis muscles were multipennate, there existed many layers of aponeurosis to which muscle fibers attached especially within the superficial portion of the masseter. The parameters of superficial portion of the masseter were statistically different from those of the deep portion, so were those of anterior portion of temporolis from those of posterior portion; the posterior part of the temporolis was the heaviest, the deep of the masseter the lightest. The physiological cross-sectional area of the superficial part of masseter was the largest, the posterior of temporolis the second, the anterior of temporolis the third, and the deep of the masseter the smallest. Among the ratios of muscle weight vs physiological cross-sectional area in each portion of the masseter and temporolis, the ratio in the deep part of masseter was the largest, that in the posterior of temporolis the smallest, that in the superficial of the masseter was similar to that in the anterior of the temporolis. In addition, the fiber in the posterior of the temporolis was the longest and that in the deep of the masseter the shortest. Conclusion: The deep portion of masseter is designed for force production, the posterior of the temporolis for velocity production, and the superficial of the masseter and the anterior of the temporolis for both force and velocity production. The deep part of masseter and the anterior of temporolis play an important part in maintaining mandibular position and balence, and the superficial of masseter and the posterior of temporolis play a major role in producing occlusive force and mandibular fast retrusion.

BACKGROUND:Bone marrow derived mesenchymal stem cells (BMMSCs) have multi-differentiation potentials, possessing a repairing capability for the sectional bone defects if combined with degradable porous β-tricalcium phosphate china. This provides a new idea in clinical repair of various bone defects.OBJECTIVE: To explore in radiology the curative effect of implanting porous β-tricalcium phosphate and autogenous BMMSCs compound to treat bone defects.DESIGN: A randomized controlled study with callus growth at various healing periods as subjects for observation. SETTING: Department of Orthopaedics, Renmin Hospital, Wuhan University; Tissue Engineering Center, Research Institute of Basic Medicine,Academy of Military Medical Sciences of Chinese PLAMATERIALS: This experiment was carried out at the Tissue Engineering Center, Research Institute of Basic Medicine, Academy of Military Medical Sciences of Chinese PLA between March and September 2002. Twenty China healthy adult sheep were randomized into the groups of blank control group (4 sheep), simple implantation group (8 sheep) and complex implantation group (8 sheep).METHODS: Under general anesthesia and aseptic condition, 10-15 mL of sheep marrow was extracted; MSCs were separated and cultured before combined with porous β-tricalcium phosphate china for tissue engineering bone construction. Rats in each group were cut off 21mm long metatarsus in the middle section of metatarsus bonestem. Β-tricalcium phosphate china and autogenous MSC compound was implanted into the sheep of the complex implantation group; β-tricalcium phosphate china was implanted into the simple implantation group; and the bone defects in the blank control group remained untouched. Then the incision was sutured.X-ray filming was carried out right after the operation, as well as 1, 3,and 6 months after the operation for radiological appraisal (scored for1 if bone union formed in one surface of bone defect, but scored 0 if no boneunion formed in any surface of bone defect, and scored 4 if bone union formed in front, back, lateral surfaces and the center of bone defect), Xray radiation-resisting density was analyzed to compare the results of bone defect repair.MAIN OUTCOME MEASURES: The postoperative general condition and general observation, as well as the results of the radiological analysis of the bone defects of all sheep.RESULTS: Totally 20 sheep were brought into this xperiment and all entered the stage of result analysis. ① The postoperative general condition:Sheep regained consciousness 2-6 hours after the operation without incision infection and loosing of internal fixation. Their spirit gradually was back to normal 1 week after the operation, at which time the injured legs could touch ground but were incapable of bearing load, and the affected legs could bear load 2 weeks after the operation, walked slightly lamely 3 weeks after the operation, and even moved freely without limp 4 weeks after the operation. ②The general condition 6 months after the operation: In pure implantation group, the surface white hyaline cartilage-like tissues were gradually calcified, with both ends connected with the host bone by bone bridge, but china granules could still be easily observed; while no implantation substance could be observed in compound implantation group,with the boundary between implantation substance and host bone vanished,and bone defect became basically the same as host bone. However there was no bone tissue formed in bone defect at various postoperative time points in the blank control group. ③ Radiological analysis of the bone defects at various postoperative time points: The radiological rating score was obviously higher in complex implantation group at the time poin ts of 3, 6 months after the operation compared with the pure implantation group [(2.3±0.3), (1.8±0.5); (3.3±0.5), (2.6±0.6), P ＜ 0.05]. ④ Radiological analysis of bone callus thickness and the relative value of radiation-resisting density at various postoperative time points: The bone callus thickness in the complex implantation group was obviously lower than that of the pure implantation group at the postoperative time point of 6 months (4.62 vs 7.64, P ＜ 0.05), with relative value of radiation-resisting density obviously higher than that of the pure implantation group (70.4±1.5 vs 61.18±1.2, P ＜ 0.05).CONCLUSION: Radiological appraisal and bone defect density measurement can well reflect the dynamical repairing process of bone defects; the implantation of porous β-tricalcium phosphate china and autogenous BMMSCs compound into sheep can enhance the repair of large sectional bone defect.
