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

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 explore whether there is any abnormality in the tongue position of the open bite. Methods Tongue position was defined as the relative position of its body in the oral proper cavity on profile cephalometric roentgenogram which was enhanced by the iodine oil applied to the tongue surface. The tongue position was compared between open bite group and normal bite group with student's t test to determine the variation of open bite. Results Compared to the normal bite group, the root of tongue was closer to the uvula in the open bite group, and the distance between the dorsum of tongue and the surface of palate was decreased as well as the tip of tongue was nearer to the incisors. Conclusion The open bite's tongue position is characterized by more upward and more forward and this position may be one of the causes of open bite.

Objective To study the value of CT and MRI in the diagnosis of hepatocellular adenoma(HCA).Methods The comprehensive imaging features of HCA in 11 patients confirmed by pathology were analyzed retrospectively in our hospital.Results 11 patients presented with a total of 18 lesions, and plain CT showed low or slightly low density in all lesions, with irregular high density area in two lesions.The CT values of the lesions were significantly higher than in adjacent normal liver in the arterial phases(P<0.05).On T1WI, two lesions showed low or slightly low signal intensity, and 16 lesions showed slight hyperintensity.On T2WI, 14 lesions showed hyperintensity, and 4 lesions showed hypointensity.All lesions showed significant enhancement in arterial phase of dynamic enhanced scanning.Pseudocapsule enhancement was revealed in 17 lesions.For 18 lesions, ADC values were measured on DWI, and the ADC values of the lesions were higher than the value of surrounding normal liver parenchyma.Conclusion Dynamic contrast-enhanced CT combined with MRI and ADC value measurement can provide valuable information in diagnosis of HCA.
