Objective To observe the therapeutic effects of fenestration in the treatment of dentigerous cyst in mixed dentition stage. Methods From 2004 to 2007, 8 cases of dentigerous cyst in mixed dentition stage were treated, among whom 3 were boys and 5 were girls with ages between 7 and 12 years old. The dentigerous cysts of 2 cases were in superior maxillary bone and the other 6 cases were in inferior maxillary bone. Each of 5 cases had one tooth in dentigerous cyst cavity, and each of the other 3 had 3 teeth in dentigerous cyst cavity. All patients received fenestration under local anesthesia. The patients were followed up for 18 months after fenestration, and the soft tissue healing, facial malformation, permanent teeth eruption and bone tissue healing were observed. Results It was found during follow up that cyst cavity disappeared in all the patients and all had normal facial morphology with no maxillary bone malformation. In five cases, permanent teeth erupted totally and dental occlusion kept normal. In one case, 2/3 of permanent teeth erupted and dental occlusion kept almost normal. While in the other two cases, permanent teeth were to erupt. It was revealed by X ray examinations that the shadow of maxillary bone density decrease disappeared in all the patients. Conclusion Fenestration can keep the teeth and bone in the treatment of dentigerous cyst in the mixed dentition stage.

This study aims to analyse the value of CODEHOP RT-PCR in the detection of Flavivirus. According to the amino acid sequences of polyproteins of different flaviviruses published in GenBank, a pair of primers was designed using the CODEHOP method. One-step RT-PCR was used to detect Japanese encephalitis virus strain JEV1201, Dengue virus strain JKD001, and yellow fever virus vaccine YV6161. BLAST analysis and phylogenetic analysis were performed after the RT-PCR products of nucleocapsid genes were sequenced. The results showed that this method could amplify Flavivirus specifically, and the size and sequence of the target fragment accorded with the anticipated result. JEV1201 had the highest homology to Japanese encephalitis virus strain YL2009-4/YC2009-3, belonging to the branch of the phylogenetic tree of Japanese encephalitis virus strains. JKD001 had the highest homology to Dengue virus strain DENV-2/ID/1022DN/1975, belonging to the branch of the phylogenetic tree of Dengue virus strains. YV6161 had the highest homology to Yellow fever virus strain 17D, belonging to the branch of the phylogenetic tree of Yellow fever virus strains. In conclusion, the method of CODEHOP RT-PCR can be effectively used to detect, identify, and phylogenetically analyse Flavivirus.

In order to evaluate the characteristics of the spray drying of total flavonoids of Epimedium extracts assisted with soybean polysaccharide, a certain percentage of soybean polysaccharide or polyvidone were added to the total flavonoids of Epimedium extract to conduct the spray drying. The effect of soybean polysaccharides against the wall sticking effect of the spray drying was detected, as well as the powder property of total flavonoids of Epimedium spray drying powder and the dissolution in vitro behavior of the effective component. Compared with the total flavonoids of Epimedium spray drying powder, soybean polysaccharide revealed a significant anti-wall sticking effect. The spray drying power which had no notable change in the grain size made a increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior. It was worth further studying the application of soybean polysaccharide in spray drying power of traditional Chinese medicine.

OBJECTIVETo study the inhibitory effect and mechanism of Ganoderma lipsiense extract (GLE) on the growth of triple-negative breast cancer (TNBC) cell line MDA-MB-231-HM in a mouse model.
METHODSThe mouse model of TNBC was established by subcutaneous injection of 1.5 x 10(6) of MDA-MB-231-HM cells into BALB/c-nu mouse. Twenty successfully modeled mice were divided into the GLE group and the negative control group according to random digit table, 10 in each group. GLE (0.2 mL 100 mg/mL) was peritoneally injected to mice in the GLE group, while equal dose of normal saline was peritoneally injected to mice in the negative control group. The medication was administered once per 3 days and discontinued after 45 days. The CD34 expression was detected using immunohistochemical assay for counting microvessels. Meanwhile, expressions of thrombospondin 1 (TSP-1) and cyclin D1 were detected using immunohistochemical assay.
RESULTSThe average weight was obviously lower in the GLE group than in the negative control group [(0.33 ± 0.16) g vs (0.68 ± 0.37)g, P < 0.05]. The tumor inhibition rate was 51.4% in the GLE group. The volume of transplanted tumor was obviously lesser in the GLE group than in the negative control group (P < 0.05). Results of immunohistochemical staining showed, the microvessel density (MVD) under every field was (20.7 ± 2.1), TSP-1 positive cell count was (66.2 ± 9.2), cyclin D1 positive cell count was (33.8 ± 16.4) in the GLE group, and they were 34.0 ± 2.0, 24.0 ± 6.6, and 168.2 ± 32.6, respectively in the negative control group. There was statistical difference in all indices between the two groups (P < 0.05).
CONCLUSIONGLE could inhibit malignant proliferation of tumor cells by suppressing angiogenesis of blood vessels in tumor tissues and regulating cell cycles, thereby inhibiting TNBC.

OBJECTIVE:
To detect the serum level of a novel autoantibody, anti-tubulin-α-1C, in patients with systemic sclerosis (SSc) and to investigate its clinical significance.
METHODS:
Anti-tubulin-α-1C antibody levels were determined by enzyme-linked immunosorbent assay (ELISA) in 62 patients with SSc, 38 systemic lupus erythematosus (SLE), 24 primary Sjögren's syndrome (pSS) patients, and 30 healthy controls (HCs). Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), immunoglobulin A(IgA), immunoglobulin M (IgM), immunoglobulin G (IgG), C3, C4, rheumatoid factor (RF), antinuclear antibody(ANA), anti-centromere antibodies(ACA), anticardiolipin (aCL), anti-dsDNA antibody, anti-Sm antibody, anti-RNP antibody, anti-Scl-70 antibody, anti-Ro52 antibody, anti-SSA antibody, anti-SSB antibody, centromere protein A(CENP-A), centromere protein B (CENP-B) were measured by standard laboratory techniques. Raynaud's phenomenon and modified Rodnan skin score(MRSS) were recorded to evaluate the disease status of SSc. Independent sample t test, Chi square test, Mann-Whitney U test, Spearman rank correlation were used for statistical analyses.
RESULTS:
The serum anti-tubulin-α-1C antibody concentration in SSc group was 81.24±34.38, the serum anti-tubulin-α-1C antibody concentration in SLE group was 87.84±38.52, the serum anti-tubulin-α-1C antibody concentration in pSS group was 59.79±25.24, and the serum anti-tubulin-α-1C antibody concentration in healthy group was 39.37±18.7. Multivariate analysis revealed that anti-tubulin-α-1C antibody levels were significantly increased in the SSc and SLE patients. The expression level of anti-tubulin-α-1C antibody in SSc was higher compared with the pSS group and the health control group (P < 0.01). Further analysis demonstrated that the elevated anti-tubulin-α-1C antibody were correlated with the SSc inflammation and disease activity markers ESR(r=0.313, P=0.019), The levels of anti-tubulin-α-1C antibody were also significantly correlated with MRSS(r=0.636, P < 0.01). The best cut-off value for the diagnose of SSc was 76.77 as mean+2SD value. The proportion of Raynaud's phenomenon was higher in the group of anti-tubulin-α-1C autoantibody-postive SSc patients than that in anti-tubulin-α-1C autoantibody negative group(71.4% vs. 37.5%, P=0.039). The proportions of anti-Scl-70 antibody, anti-CENP antibody and anti-cardiolipin antibody were higher in the group of anti-tubulin-α-1C autoantibody-postive SSc patients than in the anti-tubulin-α-1C autoantibody negative group (37.9% vs. 15.2%, 34.5% vs. 12.1%, 13.8 vs. 0, respectively, all P < 0.05).
CONCLUSION
Based on this explorative stu-dy, the level of anti-tubulin-α-1C antibody increased in the serum of the patients with SSc. There were correlations between anti-tubulin-α-1C autoantibody and clinical and laboratory indicators of the SSc patients. It may become a novel biomarker indicative of active SSc and could be applied in future clinical practice.
