Objective To observe the effect of triptolide on destruction of bone and joint of collageninduced arthritis (CIA) mouse. Methods Female DBA/1 mice were double immunized at the base of the tail with bovine type Ⅱ collagen (C Ⅱ). CIA mice were randomly divided into model group, methotrexate-treated group and 8.18, 16.36, 32.72 ?g/kg triptolide-treated groups. Performance of arthritis were observed regularly. Combined with radiologieal, histological methods were used, and the number of osteoelasts in bone was evaluated and analyzed with TRAP stainning. Results The clinical score and arthritis incidence of CIA mice were significantly decreased, and the number of osteoelasts in bone cavity reduced by treatment of triptolide. X-ray showed that the surface of bone of each articular was eroded, the joint space was narrow, BMD values of lumbar and knee were decreased compared with normal mice. Triptolide could significantly inhibit the damage of bones and joints of CIA mice, and increase the BMD values of lumbar and knee. Conclusion Triptolide can inhibit the damage of bones and joints of CIA mice.

Helicobacter pylori(H. pylori) has been associated with the cause of chronic gastritis, peptic ulcers and gastric cancer. Although it may be transmitted through the oral cavity, it is unknown whether the oral cavity acts as a reservoir of H. pylori. The purpose of this study was to investigate the mode of detection of H. pylori in oral cavity of adult periodontitis patients with plaque and periodontal pocket which atmosphere is grown well H. pylori. We analysed detection rate of H. pylori in saliva and subgingival plaques of 17 adult periodontitis patients without symptoms of gastroduodenal disease by nested PCR. Samples tested comprised saliva and subgingival plaques from central incisor, 1st premolar and 1st molar. H. pylori DNA was not identified in saliva from all patients. The detection rate in subgingival plaque from incisors, premolars and molars was 5.9%, 5.9% and 17.7%, respectively. In conclusion, the dental plaque and periodontal pocket (especially, of molars) in adult periodontitis can be favorable reservoir of H. pylori and may be the source of infection and transmission of H. pylori.

Retinal arteriovenous crossing sites are important because they are generally the points at which. in branch retinal obstruction, a blockage of venous blood flow occurs. We evaluated retrospectively the cases of 54 patiens wIth a recent temporal branch retinal vein occlusion to determine the relative anatomic position of the obstructed vein in relation to its crossing artery. In 54 (100%) of 54 eyes, the artery lay antenor to the vein, toward the vitreous cavity. In the control corssing site, the artery lay anterior to the vein 41.3% (J9/46) of the time (p<0.01) The second control group, which was obtained by examining all of the first-and second-order, without BRVO, consisted of 103 crossing sites. In this second control group's artenovenous crossmgs, the arteries were situated anteriorly in 83 (80.6%) of 103 crossing sites (p<0.005). Our observation that the artery lies anterior to the vein at the all of BRVO crossing sites contributes further evidence that mechanical factors play a prominent role in the causing BRVO.

PURPOSE: The purpose of this study is to describe the anglographic findings of collateral vessels in cervicofacial vascular lesions with previously ligated carotid arteries and to evaluate the extent of anglographic assessmant needed before embolization. MATERIALS AND METHODS: We retrospectively reviewed 10 cervicofacial vascular lesions with previously ligated carotid artery, which were 6 cases of arteriovenous malformation, 2 cases of carotid cavernous fistula, 1 case of hemangioma and 1 case of arteriovenous realformation with carotid cavernous fistula. The previously ligated arteries are proximal external carotid artery (n=5), branches of external carotid artery (n=2) and common carotid artery (n=3). Common carotid artery or internal carotid artery (n=9), vertebral artery (n=5), ipsilateral external carotid artery (n=4), contralateral external carotid artery (n=5), costocervical trunk (n=2), thyrocervical trunk (n=2) were assessed by conventional angiography. Angiography of both carotid and vertebral arteries was performed in 5 cases. RESULTS: The collateral vascular channels were inferolateral trunk of internal carotid artery (n=8), vertebral artery (n=5), contralateral external carotid artery (n=5), ipsilateral external carotid artery (n=4), deep cervical artery (n=2) and ascending cervical artery (n=l). Embolizations were performed in 9 cases with operative cannulation(n=4), embolization via collateral branches of ipsilateral external carotid artery (n=l), embolization via collateral branches of contralateral external carotid artery (n=3) and balloon occulusion via direct puncture (n=l). CONCLUSION: The collateral channels in cervicofacial vascular lesions with previouly ligated carotid artery were inferolateral trunk of internal carotid artery, contralateral or ipsilateral external carotid artery, vertebral artery, deep cervical artery and ascending cervical artery on angiography. Complete anglographic assessment of possible collateral channels is mandatory for the effective and safe embolization.

A Macular hole may change in size of the hole; may increase in size with time and an epiretinal membrane may form. Rarely, a rhegmatogenous retinal detachment may occur with time and long term visual acuity usually remains stable or progressively worse. But to our knowledge spontaneous disappearance of a macular hole caused by development of an epiretinal membrane with improvement in vision rarely occurs. The traumatic, full-thickness macular hole in a 15-year-old man during 3 month follow-up period, changed its biomicroscopic appearance and fluorescein angiographic finding. Furthermore, visual acuity showed some improvement. The authors believe this spontaneous disappearance of macular hole is probably occured as a result of epiretinal membrane formation.

Objective To investigate numerical distance effect of numerical processing in amblyopic children aged from 6 to 13. Methods 46 amblyopic children and 43 control children with normal sight were divided into 3 groups respectively:7Y group (6~8 years old),9Y group (9~10 years old) and 12Y group (11~13 years old). The numerical comparison task (judging the magnitude of number) was used in this study and error rate( ER) and reaction times ( RTs) were recorded. Results ( 1) RTs of judging the num-ber 4 (7Y group (995±100)ms,9Y group (964±141)ms,12Y group (701±125)ms) were significant lon-ger(P<0.05) than RTs of judging the number 1((882±140)ms,(790±119)ms,(550±41)ms) in 3 control groups;RTs of judging the number 6((968±116)ms,(918±126)ms,(712±125)ms) were significant lon-ger(P<0.05) than RTs of judging the number 9((862±121)ms,(774±151)ms,(625±141)ms). (2) In the 12Y group of amblyopic children:RTs of judging the number 4((942±107)ms) were significant longer (P<0.05) than RTs for judging the number 1((847±136)ms). (3) No developmental significant difference was found neither within the control children nor within amblyopic children using the RTs D-values which gained by the RTs of far distant numbers ( 1/2/8/9 ) minus close distant numbers ( 3/4/6/7 ) . Conclu-sion Only 12Y group of amblyopic children show numerical distance effect in subitizing(>5).The develop-ment of numerical processing in amblyopic children is slower than that in children with normal sight.

BACKGROUND: Cytosolic Ca2+ overload and oxygen derived free radicals may contribute to stunned myocardium. The pnt study was aimed to investigate the effects of nicardipine and sodium nitroprusside (SNP) on the functional recovery of postischemic reperfused myocardium. METHODS: Fifty-seven halothane-anesthetized dogs were subjected to 15 minutes of 1eft anterior descending coronary artery (LAD) occlusion and 3 hours of reperfusion. They were randomly assigned to receive either intracoronary nicardipine (n=11) or SNP (n=10) alone or both (nicardipine plus SNP, n=10). Eleven dogs that received saline i.c. served as the controL Regional myocardial contractility was evaluated by systolic shortening (%SS), the preload recruitable stroke work slope (Mw), and intramyocardial pressure (IMPs). Diastolic function was assessed by time constant of myocardial relaxation (IMP-tau) and postsystolic shortening (%PSS), LAD blood flow was measured by a Doppler flowmeter as well. RESULTS: LAD occlusion produced a significant reduction in systolic as well as diasto1ic functions to similar degrees in all groups. However, %SS was significantly higher in the nicardipine, SNP and nicardipine-SNP groups (67%, 56%, and 68% of baseline values, respectively) than in the controls (20%) at 3 hours of reperfusion. Furthermore, Mw recovered to the baseline with the onset of reperfusian in the three experimental groups. IMP-tau was restored to the baseline during early nperfusion in the SNP-treated groups but was significantly prolonged in the control and nicardipine poups throughout the seperfusion. LAD blood flow during reperfusion was higher in the SNP-treated groups in comparison to the control group. CONCLUSIONS: Treatment with either nicardipine or SNP enhances the recovery of mgional contractile function in the canine model of myocardial stunning. SNP not nicardipine is also beneficial in attenuation of early diastolic dysfunction. Nicardipine combined with SNP improved systolic as well as early diastolic functions more significantly when compared to either nicardipine or SNP alane.
