Journal of Practical Stomatology 2000;0(05):-
Objective: To evaluate the remineralizing effe ct of glass ionomer cement (GIC),calcium hydroxide(Dycal)and zinc phosphate ceme nt on soft dentin. Methods:Standard cavity of 1 mm?2 mm was pre pared on each of the 60 premolars extracted for orthodontic treatment. The teeth were randomly divided into three groups with 20 in each after demineralization ,the cavities were blocked by GIC, Dycal and zinc phosphate cement respectively and filled with zinc oxide. All the teeth were dipped in man-made saliva for 3 0 days.Then the samples were sectioned, microradiographied and the mineral conte nt were determined by microdensitometry. Results:The remineraliz ing rate in the group of GIC, Dycal and zinc phosphate cement was 31.22%,13.19 % and 8.92% respectively (P

Objective To investigate the onset and risk factors of the transient ischemic attack of vertebrobasilar artery vertige in old patients. Methods Patients were divided into group A, group B, group C based on attack times of vertige and whether cerebral thrombosis was formed within half a year. Blood biochemistry index, blood pressure variation, carotid ultrasonic examination results in the first 24 hours were compared. Results High sensitive C-reactive protein (hs-CRP), systolic blood pressure (SBP), diastolic blood pressure(DBP), blood sugar(BS), cholesterol(TC), triglyceride(TG), common carotid artery resistance of group A index(CCARI), internal carotid artery resistance index(ICARI) and atherosis plaque index in the first 24 hours were significantly lower than those of group C (P0.05). Logistic regression indicated that hs-CRP, DBP, BS, TC, CCARI, ICARI and plaque index were correlated with risk factors of the transient ischemic attack of vertebrobasilar artery vertige and cerebral thrombosis in old patients. Conclusion hs-CRP, SBP, BS, TC, CCARI, ICARI and plaque index elevation might be an early warning index for the unstability and easy drop of the carotid's plaque.

Pathology rotation is an important part in resident standardization training. Impor-tance should be attached to the residents' learning during the standardization training in Pathology De-partment, such as standardizing training and strict departmental rotation examination, developing the residents' thinking ability of the relationship between clinical and pathology with the main line of spe-cialty pathology learning , and improving clinical research capacity through pathology technical methods and principles, and training pathology literacy from pathology requisition filled to interpreta-tion of the pathology report, which will also help to improve the medical service quality of the hospital.

Objective To explore the significance of palpation-negative breast tumor resection with ultrasound-guided methylene blue labeling and percutaneous suture traction.Methods 46 cases of small breast tumors with the diameter from 0.5 cm to 1.0 cm were double labeled with methylene blue under the guide of ultrasound l hour preoperatively.The tumors were fixed,drew outward with percutaneous suture and resected accurately.All the 46 cases were rechecked by ultrasound to verify whether residual or false resection occurred 1 month later.Results All the 58 tumors of the 46 patients were accurately resected.No residue or false resection occurred.The average operation duration was 10 min to 20 min.Conclusion Palpable-negative breast tumor resection with ultrasound-guided methylene blue labeling and percutaneous suture traction has the advantages of small invasion,accurate positioning and short operation duration.

Objective To investigate the tear fdm function with Graves disease.Methods Seven-ty-eight patients with Graves disease were studied respectiveIy,40 cases healthy person as contr01.Tear film function Was evaluated by tear break-up time(TBUT),Schirmer I test(SIT),corneal fluorescein staining,dry eye and unwell symptoms.Results The difference of TBUT and SIT resultsbetweenpatients and con-trois were significant(P<0.05).The rate ofTBUT,corneal fluorescein staining and symptom ofdry eye in patients were significantly higher than those in controls.Conclusions Graves disease patients have higher rate of abnormal tear film function in comparison with controls.Graves disease are correlated with xerophthalmia.

ObjectiveTo evaluate the efficacy and safety of tirofiban in treatment of ST segment elevation acute myocardial infarction(STEAMI) no-reflow and acute thrombosis after emergency percutaneous coronary intervention(PCI). MethodsForty patients which were made definite diagnosis of STEAMI were intra-coronary artary injection fortirofiban after emergency PCI stenting occured no-reflow and acute thrombosis. First,the dose of 0.4μg·kg-1·min-1 was given from intra--coronary artary injection of tirofiban within three minutes, after 30min the dose were given 0.1μg·kg-1·min-1 for 48 hours. ResultsThe no re-flow and acute thrombosis was completely disappeared within five minutes,at the time,side effect with in one week was not observed. ConclusionsTirofiban treatment by direct injection in coronary arteries combined with emergency PCI, can increase the repeffusion rate of infarction related vessel in AMI patients,and improve TIMI reflow. This reperfusion method was effective and safe.

Objective We invented mammary lump skin-positioning membrane (named scare membrane) to facilitate localization of mammary lump during ultrasound scan.This study is to measure the radius of mammary of Chinese adult women for designing different types of skin-positioning membrane.MethodsThe radius of mammary glands in 236 cases of adult females was detected with color Doppler ultrasound at 5 different clock positions:12:00,3:00,6:00,9:00 and 10:30 or 1:30.SPSS 16.0 statistical software was used to analyze the data.The cut-off values of mammary glands radius at 99%,95%,75% and 50% were calculated.Paired t tests or nonparametric tests (relative sample rank sum tests) were used to verify the consistency of mammary gland radius between left and right sides.ResultsThe cut-off value of 95% mammary gland radius was:7.700cm at 12:00,7.810 cm at 13:00,8.100 cm at 3:00,5.330 cm at 6:00 and 6.300 cm at 9:00 for left mammary gland ; 7.500 cm at 12:00,6.015 cm at 3:00,5.500 cm at 6:00,8.510 cm at 9:00 and 7.930 cm at 10:30 for right mammary gland.In comparison of left and right mammary gland radius,the difference had statistical significance between the group of left side at 1:30 and right side at 10:30,the group of left side at 3:00 and right side at 9:00(P <0.05).The right mamma was relatively larger.The cut-off values of the right mamma at the above two clock points were taken as radius of scale membranes while the average of percentage cut-off values at 12:00,3:00 of both mammas,left side at 9:00 and right side at 3:00 are taken as radius of scale membranes.ConclusionsAccording to the cut-off values of 99%,95%,75% and 50% radius of adult female mammary glands,mammary lump skin-positioning membrane radius can be classified into 4 size-types:extra large,large,medium and small.The precise classification of radius of mammary scale membranes according to mammary glands of adult females provides convenience for production,manufacture and clinical application of mammary lump skin-positioning membrane.

OBJECTIVE: To explore the pathogenesis characteristics of variant angina pectoris (VAP) by extracting its syndrome elements and analyzing the combination and distribution regularity of the syndrome elements. METHODS: One hundred and seventy-five case files of VAP patients were collected. The extraction of syndrome elements and symptom contribution to syndrome was completed by the partition method of complex system based on entropy theory. Diagnostic threshold was established by receiver operator characteristic curve. According to the results diagnosed by diagnostic criteria for syndrome element with quantitation, the combination and distribution regularity of the syndrome elements in patients with VAP was analyzed. RESULTS: The basic syndrome elements in the patients with VAP were qi deficiency, qi stagnation, blood stasis, phlegm turbidity, phlegm-heat, stagnation-heat, yin deficiency and yang deficiency syndromes. It showed that the combination types of syndrome elements could be made up of one syndrome, two, three, four or more than four syndromes. Qi deficiency, yin deficiency, qi stagnation, blood stasis and phlegm turbidity syndromes had the higher frequency than other syndrome elements in the patients with VAP. CONCLUSION: The partition method of complex system based on entropy theory can be used in extracting the syndrome elements of the patients with VAP. It is found that VAP has complicated pathogenesis according to the combination and distribution regularity of syndrome elements. Qi deficiency, qi stagnation, blood stasis, phlegm turbidity and yin deficiency syndromes are the main syndrome elements.
