Objective:To study the characters of perioral muscle p re ssure of the adult patients with skeletal crossbite. Methods:20 patients were diagnosed to be with skeletal crossbite. The perioral muscle press ures on upper and lower central incisors, first molars and cuspids were measured buccally and lingually at rest position. 10 health adults were served as the co ntrols. Results:The perioral force in skeletal crossbite group was larger than that in the control group on the correspondence area(P0.05). In the skeletal cross bite group, the perioral force on the mandibular area was larger than that on th e correspondence maxillary area(P0.05). The muscle pressure on the labial side was larger than that on t he lingual correspondence side in both groups(P

BACKGROUND:In the repair of urinary tract defects, we have been actively trying to construct the urinary tract substitutes with normal physiological function through combining ideal seed cel s and proper scaffold materials by tissue engineering method. OBJECTIVE:To investigate the biocompatibility of bone marrow mesenchymal stem cel s with rabbit bladder acel ular matrix scaffold. METHODS:Rabbit bone marrow mesenchymal stem cel s were isolated and cultured using density gradient centrifugation method. Passage 3 rabbit bone marrow mesenchymal stem cel s were cultured on the rabbit bladder acel ular matrix. The cel s were counted every day for 12 days, to drawn a cel growth curve. Bone marrow mesenchymal stem cel s cultured alone were used as control group. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s were successful y seeded onto the bladder acel ular matrix. Under the inverted microscope, the cel s grew out of the bladder acel ular matrix, and a great amount of long spindle-shaped cel s were found around the bladder acel ular matrix. With 5 days of inoculation, the cel s in the two groups grew gently;at 6-9 days, the cel growth curve gradual y became steeper, and the cel division and growth were increased exponential y;at 10-12 days, the cel s recovered to a gentle state. Cel growth curves in the two groups were basical y coincident, suggesting that rabbit bone marrow mesenchymal stem cel s have good biocompatibility with the bladder matrix.

Objective To investigate the effect and safety of Ropivacaine mesylate in combined spinal-epid uaral anesthesia of hypogastric operations of elder patient.Methods 90 cases patients scheduled for the lower abdominal surgery were randomly divided into two groups(appendectomy and Oblique inguinal hernia neoplasty).group Ropivacaine mesylate(group A,n=45),group upivacaine hydrochloride(group B,n=45),A,B groups,punctures were selected between L2～L3 ,Hyperbaric solution of Ropivacaine mesylate were injected intrathecaly respectively in two groups,(compounding:group A:0.894% Ropivacaine hydrochloride 1.5ml+10% Glucose lml)and group B;(0.75% Bupivacaine hydrochloride 1.5ml+10% Glucose lml).The two groups after the subarachnoid medication Indwelling catheter to the cephalic in the epidural space.The time of anaesthetic emergence,maintainance,and the anaesthetic level were observed;the analgetic effect was assessed;movement signs of the lower limbs were observed;blood pressure,respiration and SpO2 .postoperative complications were observed.Results There was apparent differentiation between group A which Systob'c blood pressure declined 8.9% ,heart rate decreased 6.7% ,intraoperative nausea came up to 6.7% after anaesthesia and group B which was 28.9% ,20% ,17.8% ,respectively(P ＜ 0.05).The effective time of anaesthetic emergence was(52.0 ±21.5)s and(13.2 ±3.3)min in group A longer than group B was(41.2±18.2)s and(11.3 ±3.6)min(P＜0.01).There was no difference in Sp02,Bromage Score about extreme movement blockage degree(2.3 ±0.7;2.2 ±0.5),the incidence of postoprative headache(0% ;2.2%)between the group A and group B(P ＞ 0.05).Conclusion Ropivacaine mesylate can be used effectively and safetly in combined spinal-epiduaral anesthesia applied in hypogastric operations of elder patients,for cardiovascular stability is superior to bupivacaine.

Objective: To examine the skeletal factors of Angle's classⅡdivision 1 malocclusion in order to find a reasonable treatment protocol. Methods: The skeletal factors were measured and compared between 86 cases aged 12～25 years with AngleⅡ 1 malocclusion and 86 cases at the same age with normal occlusion. Thirteen measurements were chosen on lateral cephalometric radiograph for the comparison. Results: In the group of maloculsion, some measurements standing for sagittal skeletal pattern were statistically defferent from those in the group of normal occlusion, such as decreased SNB angle and SL linear and increased ANB angle, whereas some were not significently different, such as the SNA angle and PNS-ANS linear; some measurements standing for the vertical skeletal pattern were statistically defferent, such as decreased UM-PP linear and LM-MP linear and increased UI-PP linear, whereas some were not significently different, such as LI-PP linear;some measurements standing for growth pattern of mandibular were statistically defferent, such as decreased SN-MP angle. Conclusion: There are posterior alveolar defficency and mandibular retroposition as well as counterclockwise rotation of mandile in the patients with Angle class Ⅱ 1 malocclusion. The treatment for Angle Ⅱ 1 malocclusion should be to make mandibular move forward and downward in accordance with the characteristic skeletal pattern.
