Objective: To evaluate the eruption of mandible third molar in orthodontic patients with non-extraction or extraction of the lower premolars. Methods: We selected 3 group of the orthodontic patients. One group consisted of 23 subjects (12 males, 11 females, average age 13.5 years) with non-extraction. One group consisted of 23 subjects (12 males, 11 females, average age 13 years) with lower first premolar extraction. One group consisted of 21 subjects (11 males, 10 females, average age 14.07 years) with lower second premolar extraction. The panoramic radiography was taken. The lower third molar angulation and eruption space were measured before and after the orthodontic treatment. The comparison of treatment changes in 3 groups were performed by means of a paired-sample t test using SPSS 17.0 software package. Results: The RS, LS, Rratio and Lratio increased significantly after treatment in patients with lower first premolar extraction(P<0.01). The RM3 and LM3 increased(P<0.05) and RS, LS, Rratio and Lratio increased significantly(P<0.01) after treatment in patients with lower second premolar extraction(P<0.05). Conclusion: The mandibular third molars show improvement in eruption space and inclination in the orthodontic patients with lower premolar extraction.

Objective To investigate the alteration of phosphorylated GluR1Ser831 and behavioural effects in a rat model of levodopa-induced motor complications after Ca2 +/calmodulin-dependent protein kinase Ⅱ (CaMKⅡ) inhibitor KN-93 treatment. Methods The hemi-parkinsonian rat model was produced by injecting stereotaxically 6-OHDA to right medial forebrain bundle. Then, rats were intraperitoneally treated with levodopa ( 50 mg/kg with benserazide 12.5 mg/kg,twice daily) for 22 days. On day 23 ,rats received KN-93 before levodopa administration. Rotational duration was estimated. After sacrificed, subcellualr distribution of GluR1 and phosphorylated GluR1Ser831 were observed by western blot. Results The study showed that CaMKⅡ inhibitor KN-93 prolonged rotational duration. Moreover, KN-93 could regulate subcellular distribution of GluR1 and reduce hyperphosphorylation of GluR1 Ser831, which was closely associated with levodopa-induced motor complications. The expression of membrane GluR1 and phosphorylated GluR1Ser831 was (83.4 ±4.2)% and (47.2 ±5.2)% ,respectively. Conclusions These results indicated that activation of CaMKⅡ contributed to development of motor complications, through a mechanism that involved an increase in phosphorylated GluR1 Ser831. Pharmaceuticals which act to inhibit CaMKⅡ may be useful in the treatment of the motor complications in parkinsonian patients.

BACKGROUND: The key point in the treatment of acute cerebral infarction lies in inproving the blood supply of brain effectively as soon as possible as well as rescue ischemic and half diazonal nerve cells, so as to contract the local of infarction as great as possible.OBJECTIVE: To observe the effect of traditional treatment of cerebral piamatral microcirculation in gerbil with cerebral ischemic reperfusion injury by supplementing qi and activating blood circulation.DESIGN: Contrast animal experiment at random.SETTING: Zhabei Branch of Shanghai Changzheng Hospital.MATERIALS: The experiment was performed in the Institute of Naval Medicine (key laboratory of the whole army). Twenty-two healthy Monglian gerbils of clean grade (six months old) were selected and randomly divided into medicine group and control group with 11 gerbils in each group.METHODS: Animals were routinely anaesthetized and fixed in prone position to open the cranium window in median line and expose the pia mater. The cranium window was protected by being covered with a cotton ball containing artificial cerebrospinal fluid (ACSF) after operation. Gerbils were fixed in dorsal position with an median incision made in the lateral cervical nucleus to isolate and expose bilateral common carotid artery (CCA). The bilateral CCA were occluded by atraumatic micro-bulldog clamp, and the occluded blood flow in the distal end was observed under the microscope. Thirty minutes after occlusion of bilateral CCA, the vascular clamp was unclamped to recover the cerebral blood reperfusion. Gerbils in the medicine group were abdominally injected with 0.4 mL of Huangqi injection (containing 0.8 g of crude drug), 0.3 mL of compound Danggui injection (containing Danggui, Chuanqiong and Honghua, 0.09 g for each)and 0.3 mL of Danshen injection (containing 0.45 g of Shengyao). Animals in the control group were abdominally injected with same-volume of normal saline. The changes of pial microcirculation were quantitatively observed in two groups through cranium window respectively before blockage, at the reperfusion after blockage as well as in 120 minutes after injection by laser microcirculation microscope and the TV video system.MAIN OUTCOME MEASURES: The changes of piamatral microcirculation as well as comparison in venous blood flow velocity in gerbils of each group before and after ischemic reperfusion.RESULTS: All gerbils were involved in the analysis of results with no animal died in the experiment.①When the CCA of animals in the two groups were blocked, obvious contraction of piamatral microcirculation was seen and partial blood vessels were blocked up. Platelet and red blood cells etc.adhered to the arteriolae of grade Ⅰ and veinules below grade Ⅲ with microthrombus formed and large ischemic area appeared. The blood flow rate was obviously slowed down. Moderate and severe aggregations were found in red blood cells, and the white blood cells were significantly increased.There was obvious exudation in the periphery of microvessels. After CCA reperfusion, the arteriolae and veinule were in different thickness, and the thrombus in veinule of grade Ⅰ and Ⅱ formed in the cerebral ischemia were difficult to be removed by blood flow. Red blood cell moderately aggregated, and the number of white blood cells greatly increased. White small thrombus could be seen sometimes, while the exsudation in the periphery of microvessel was not significantly ameliorated. Great changes were found in gerbils of the medicine group after abnormal injection of supplementing qi and activating blood circulation medicine: almost all arteriolae and venulae were opened, and the rate of blood flow was accelerated with the blood flow rate remarkably increased. Deposit in the venulae began to decreased, and the thrombus was gradually dissolved. Red blood cells were moderately aggregated or normal. Blood flow in ischemic spot was improved significantly than that after reperfusion. The exudation in the periphery of microvessels was gradually lessened even dissolved. However,no obvious change was found in gerbils of the control group. ②The blood flow rate of arteriole in the medicine group was 1.04-1.50 mm, which was obviously higher than that in the control group with significant differences (P ＜ 0.5-0.01).③The blood flow rate of veinule in the medicine group was 0.96-1.12 mm/s, which was remarkably higher than that in the control group with marked differences (P ＜ 0.05-0.01).CONCLUSION: The effect on piamatral microcirculation of gerbil with cerebral ischemic reperfusion by supplementing qi and activating blood is exact, which is directly related with accelerated blood flow rate, expanded veinule and arteriolae as well as ameliorated blood-supply of brain.
