Enzyme-linked immunosorbent assay for determination of thyroid-stimulating antibody in the sera of patients with Graves' disease was established using ganglioside (GLS) purified from bovine brain as binder. It was applied in clinical practice. The results showed that LATS could react with ganglioside under suitable conditions. Very significant difference was observed between normal subjects and untreated GD (P

Objective To quantitatively assess the regional myocardial function in the patients with heart failure by tissue Doppler imaging. Methods The apical 4 chamber, 2 chamber and long axis view of two-dimensional tissue Doppler imaging were acquired in 30 healthy individuals and 18 patients with heart failure by GE Vivid 7 commercially machine.The basal and middle segments in left and right ventricle were analyzed in tissue velocity imaging model. The following cardiac intervals and velocities were measured in each segment, including the isovolumetric contraction time(IVCT), the ejection time, the isovolumetric relaxation time(IVRT); the rapid filling time, the artrial systolic time, the peak velocity and acceleration of Sm, the peak velocity and acceleration of Em, and the peak velocity and acceleration of Am. Results Compared with control group, IVCT, IVRT and atrial contraction time were prolonged, the ejection time and rapid filling time were shorterned, peak velocity and acceleration of Sm, Em, and Am were reduced in heart failure group. Conclusions There were characteristic changes on tissue velocity imaging in the patients with heart failure which include the delay of IVCT and IVRT and reduction of velocity in Sm, Em, and Am.

Objective To quantitatively assess cardiac intervals with tissue Doppler imaging(TDI) and normal reference values. Methods Apical 4 chamber, 2 chamber and long axis views of two-dimensional TDI were acquired in 29 healthy individuals(using GE Vivid 7 commercially ultrasound machine). The basal and middle segments in left ventricle(anterior septal, anterior, lateral, posterior, inferior and septal wall) and in the free wall of right ventricle were analyzed with tissue velocity imaging(TVI) model.Cardiac intervals of each segment, which included the isovolumic contraction time, contraction to peak time, insovolumetric relaxation time, rapid filling time and artrial contraction time were measured using TVI in the left ventricle and free wall of the right ventricle. Results The successful rate of sample was 100% in basal segment of each wall. There were significant differences between the left and right ventricle in the isovolumetric contraction time, the systolic accelaration time, contraction to peak time, isovolumetric relaxation time, early diastolic time, diastasis and artrial contraction( P

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.

BACKGROUND: Studies have demonstrated that exogenous basic fibroblast growth factor (bFGF) has intensive effects to promote proliferation of gingival fibroblasts (GFs) cultured in vitro and the heeling of gingival wounds. OBJECTIVE: To investigate the effects of bFGF gene transfection on the biological performance of Beagle canine GFs. DESIGN, TIME AND SETTING: An observation and comparison in vitro experiment regarding cells was accomplished in Centre of Cell Biology and Development of Fujian Medical University and Department of Comparative Medicine in Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from April to September of 2008. MATERIALS: Four beagle dogs, male, 12 months old, weighing 10-13 kg were used in this experiment, plRES2-EGFP-bFGF plasmid containing full-length human bFGF gene cDNA was constructed and conserved by our institution. METHODS: Free gingiva of the 2nd, 3rd and 4th premolars were excised from left upper jaw of Beagle dogs, dnsed with aseptic phosphate buffer four times, then cut into pieces and digested with 2.5 g/L pancreetin for 2 hours at 37 ℃. After the cantrifugation and supernatant removal, DMEM containing 10% fetal bovine serum was added to incubate on 6-well plate with coverlips in 5% CO2 incubator at 37 ℃. Logadthrnically growing cells were digested and passaged. GFs were transfected with pIRES2-EGFP-bFGF plasmid using liposome mediated method, while vacant plasmid transfection and un-transfection group served as controls.MAIN OUTCOME MEASURES: Proliferation and apoptosis feature of the GFs were evaluated by M'rE and AOEB, respectively. The activity of alkaline phosphatase was assayed by chemical coledmetry. RESULTS: All of three groups cells entered log phrase on three days after transfection. MTT results showed that the proliferation of GFs transfected with bFGF was greater than cells transfected with vacant vector and untransfected cells (P < 0.05). AO/EB dyeing showed the apoptosis rate of GFs transfected with bFGF was reduced compared with other two groups (P < 0.05). After bGFG gene transfection, the ALP activity remained unchanged and there was no significant difference compared with untransfected cells.CONCLUSION: The transfection of bFGF gene to GFs can promote the proliferation of GFs and depress the apoptosis. No promotion is present with regard to the GFs differentiation.

The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dŭ", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).
