Journal of Practical Stomatology 2010;26(1):47-50
Objective: To explore rational drug usage for periodontitis treatment through a comparative study of the efficacy of four kinds of drugs on the experimental periodontitis. Methods: 126 Wistar rats,10 randomly selected as normal control group, the other 116 were modeled by using local wire ligation and systemic prednisolone acetate injection. Successful animal models were randomly divided into model control group and berberine hydrochloride, minocycline hydrochloride, ginsenoside Rg-1 and transforming growth factor-β1 treatment groups, which were treated with each kind of medicine separately and were killed at the end of 1, 2, 4 weekend. Detected IL-1β, TNF-α, IL-6, BGP levels by immunohistochemical SABC assay. Results: IL-1β, TNF-α, IL-6 of the treatment groups were lower and BGP was higher than model control group(P<0.05).Among them, the role of berberine hydrochloride to reduce IL-1β and TNF-α was the best. The role of minocycline hydrochloride to reduce IL-6 was the fastest. The role of transforming growth factor-β1 to increase BGP was the fastest. The role of ginsenoside Rg-1 to increase BGP was more lasting and better follow-up. Berberine and ginsenoside Rg-1 reduced IL-1β, TNF-α, IL-6 and increased BGP at the same time. Conclusion: The treatment of minocycline hydrochloride and transforming growth factor-β1 are quick. Berberine and ginsenoside Rg-1, particularly berberine have the advantage of multi-targets' role.
7.Association between middle cerebral artery and it's single infarction in the territory of perforating arteries
Chinese Journal of Neurology 2008;41(12):812-815
Objective To analyze the morphologic characteristics of the single infarct in the territory of perforating arteries which arise from the middle cerebral artery (MCA),and further to investigate the association between the type of cerebral infarction and the isolated stenotic disease of the ipsilateral MCA.Methods Fifty-five patients with acute ischemic stroke who were admitted to the Department of Neurology,Peking Union Medical College Hospital,Beijing,China during January 1,2005 and December 31,2006 were identified.All of the patients had a single acute infarction in the territory of the MCA perforating arteries revealed on diffusion weighted imaging (DWI).Transcranial Doppler (TCD) and magnetic resonance angiography (MRA) were performed for all patients.Patients with stenesis >50% of proximal internal carotid artery and potential cardiac sources of embolism were excluded from the study.Patients were classified into 2 groups according to the presence of the atberosclerotic stenosis of the ipsilateral MCA: patients with or without MCA stenosis.Size of the lesions was measured including the diameter,area and volume.The infarcts with a diameter less than 2 cm were classified as lacunar infarcts; those bigger than 2 cm were classified as the striatocapsular infarcts.The infarcts on DWI was seen in basal ganglia,the body of lateral ventricle and beth.The concomitance of subcortical multiple small old infarcts or leucoariosis on T2>WI-MRI between the two groups was assessed.Results Among these 55 patients,14 (25.5%) had stenosis of the ipsilateral MCA and 41 (74.5%) had a normal MCA.In the group of MCA stenosis,71.4% patients were lacunar infarcts; 67.3% patients were also lacunar infarcts in the normal MCA group.There was no significant difference between the two groups (χ2=0.147,P=0.701).No significant difference in the diameter,area and vo|ume of the infarcts was found between the two groups.The basal ganglia,the body of lateral ventricle and both of these places involvement accounted for 31.7% ,17.1%,51.2% in the normal MCA group; 35.7%,28.6%,35.7% in the stenotic MCA group.No significant difference was found (χ2=1.272,P=0.529).Twenty-three (56.1%) patients had concomitant of small old subcortical multiple infarcts or leucoariosis in the normal MCA group and 3 (21.4%) in the MCA stenosis group,and there was a significant difference between the two groups(χ2=5.033,P=0.025).Conclusions A series of pathologic mechanisms are supposed to cause the single infarction in the territory of MCA perforating arteries.Stenosis of MCA is an underlying cause in addition to perforating artery diseases.There is no significant difference in the size,volume or distribution of the lesions between the two groups.The concomitant of subcortical multiple small old infarcts or leucoariosis may demonstrate the perforating artery disease.
8.Local recurrence of rectal carcinoma: diagnosis and treatment
International Journal of Surgery 2009;36(11):789-792
Rectal carcinoma is a common malignant tumor in China. Although it decreased greatly after the introduction of total mesorectal excision and preoperative radiotherapy, the local recurrence rate of rectal carcinoma after curative surgery is still up to 11.3%. Surgery is the most effective treatment for local recurrence of rectal carcinoma. If excised radically, the five-year survival of patients with rectal carcinoma could be more than 35%. Only a few patients will benefit from ex-tended radical surgery because of its extremely high postoperative morbidity and mortality. Strict selection of patients by mul-tiple preoperative examinations makes extended radical surgery more reasonable. For the unresectable advanced recurrent rectal carcinoma, multimodality palliative therapy could lead to symptom relief, elevated quality of life and prolonged surviv-al. We discuss the diagnosis and treatment of recurrent rectal carcinoma in this review.
9.Clinical diagnosis and analysis of ventricle aneurysm post myocardial infarction
Chinese Journal of Interventional Cardiology 2001;9(2):61-63
Objective To study the factors effecting the formation of the ventricular aneurysm post myocardial infarction (MI) and evaluate the diagnostic methods.Methods 23 MI patients with ventricular aneurysm confirmed by left ventricular angiography were observed for electrocardiogram (ECG), echocardiogram (ECHO), coronary disease and collateral vessels formation. Results All patients had LAD disease, 65.2% patients had three coronary disease, and those with class Ⅲ collateral vessels circulation only 17.4%. Compared to ECHO by which only 4 patients were found aneurysm, the positive rate by ECG was 82.6%. Conclusion Patients with multiple coronary disease and without enough collateral vessels are expected to form ventricular aneurysm. ECG is more sensitive than ECHO for diagnosis of ventricular aneurysm post MI
