Chinese Journal of Information on Traditional Chinese Medicine 2006;0(04):-
Objective To establish a method for determining the content of Danshensu and Protocatechuic Aldehyde in Huoxue capsule. Methods The HPLC method was adopted for the determination. Danshensu and Protocatechuic Aldehyde were used as the standard. Detection wave length was set at 280 nm,the mobile phase consisted of methanol-0.5 % HAc (30∶70). Results The linear range of Danshensu was 0.421~3.364 ?g and Protocatechuic Aldehyde was 0.212~1.699 ?g. The average recovery rate of Danshensu was 100.05% with RSD of 3.07% and Protocatechuic Aldehyde was 99.39% with RSD of 1.62%. Conclusion This method is accurate,specific and reliable for the quality control of Huoxue capsule.

OBJECTIVEThis study aims to investigate the caries status of the first permanent molar and primary tooth among 7- to 9-year-old children in Tangshan city and the correlation between caries of primary tooth and the first permanent molar.
METHODSA stratified cluster sampling method was used on the basis of the Basic Approach of Oral Health Survey of WHO and the Guideline of the Third National Oral Health Survey. A total of 10 primary schools were randomly sampled in clusters that included 51 primary school sampling spots in Tangshan. The caries status of 1 794 children aged 7 years to 9 years was examined.
RESULTSThe prevalence rate of the first permanent molar caries was 47.49% (852/1 794), the mean number of DMFT was 1.30 ± 1.59, the mean number of DMFS was 1.96 ± 3.40, and the filling rate was only 2.35% (20/852). The preva- lence rate and mean DMFT of the first permanent molar caries showed significant difference between different ages and genders (P < 0.05). However, the mean DMFS of the first permanent molar caries only showed significant difference between the various ages (P < 0.05). The prevalence rate of the primary tooth caries was 83.11% (1 491/1 794), the mean number of dmft was 4.82 ± 3.55, the mean number of dmfs was 6.51 ± 5.61, and the filling rate was 12.41% (185/1 491). Caries of primary tooth was the first permanent molar caries risk factor [r = 0.277, OR = 5.736, P = 0.00, 95% CI (4.175, 7.881)]. Significant correlation was found between the caries of primary tooth and first permanent molar (r = 0.274, P < 0.001).
CONCLUSIONCaries status of the first permanent molar among 7- to 9-year-old children in Tangshan city is serious. Caries status of primary tooth may play an important role in predicting the first permanent molar caries in clinic and prevention.

Objective To investigate the effects of osteopontin (OPN) antisense oligodeoxynucleotide (AS-ODN)on OPN mRNA expressions and adherence to collagen gel of rat renal mesangial cell line (1097). Methods One AS-ODN complementary chain to rat OPN cDNA sequences was designed and synthesized. All nucleotides of different kinds of oligodeoxynucleotide (including antisense, sense and mismatch sense) were modified with phosphrothioate. All the ODNs were mixed with cationic liposome(DOTAP) respectively. The cultured 1097 cells were incubated with different concentration of ODN at 37t for 48 hours, then total RNA was extracted from cultured cell line with Trizol reagent. OPN mRNA expression was detected with RNA dot blot and RT-PCR. The cell adhesion ability was measured with collagen gel attachment lest. Results OPN mRNA expression of mesangial cells was higherly upregulated in the medium with calf serum compare to that in the medium without serum. AS-ODN could suppress the expression of OPN mRNA in mesangial cells with dose-dependent and its lowest inhibitory concentration was 2. 5 ?mol/L, but mismatch ODN or sense ODN have no inhibitory effects on the OPN mRNA expression of mesangial cells even if at a high ODN concentration of 30 ?mmol/L. AS-ODN-treated cells weakly adhered to the collagen gel and could be easily detached off. The mesangial cells treated with mismatch ODN or sense ODN still had a good adherent ability to collagen gel. Conclusions Calf serum can induce rat renal mesangial cells higherly expressing OPN mRNA. Osteopontin antisense oligodeoxynucleotide can specifically suppress mesangial cells OPN mRNA expression and adhension to collagen gel.

OBJECTIVE:
To compare the effectiveness of sequential treatment for subjective and objective benign paroxysmal positional vertigo(BPPV).
METHOD:
The efficacy of sequential treatment for nineteen vertical semicircular canal S-BPPV patients(Group A) and forty-five vertical semicircular canal O-BPPV patients(Group B) who were admitted to our hospital between January 2014 and July 2015 was retrospectively analyzed and compared, treatment of five cases with horizontal semicircular canal S-BPPV was reported here as well.
RESULT:
The number of repositioning maneuver for Group A was 2 - 6 times (average: 4. 21±1. 18) while 2 - 3 times (average: 2. 29 ± 0. 46) for Group B. There was significant difference between the two groups(P<0. 01). The effective rate of initial treatment for Group A was 78. 9%(15/19) while 82. 2%(37/45)for Group B. After one weeks treatment, the effective rate for Group A changed to be 89. 5% (17/19)while 88. 9% (40/45) for Group B. Non-significant difference was found in the two groups neither in the initial nor one weeks treatment. On three months' follow-up, one in Group A and two in Group B relapsed, and they were cured after treated in the initial treatment. The recurrence for Group A was 5. 3%(1/19) while 4. 4%(2/45) for Group B and there was non-significant difference. The five cases with horizontal semicircular canal S-BPPV were completely free of disease after undergoing treatment.
CONCLUSION
The sequential treatment is effective for both vertical semicircular canal S-BPPV and vertical semicircular canal O-BPPV, but the former needs more repositioning maneuver times. The repositioning maneuver, combined with drug therapy and head-shake-in-supine-position method is recommended for horizontal semicircular canal S-BPPV.
