Objective To observe and compare the efficacy of minocycline and iodine ointment in treatment of chronic periodontitis.Methods 82 cases with chronic periodontitis collected in our hospital from January 2012 to January 2013 were randomly divided into groups A and groups B,each had 41 cases.Basic treatment included removal of local irritation,the use of subgingival scaling and root planing clear debris,plaque,tartar,adjust occlusal trauma and food impaction,with 3% hydrogen peroxide,chlorhexidine solution rinse the periodontal pocket were used in both two groups.Group A was added minocycline,and group B were added iodine glycerin on the basis of basic treatment.The changes of periodontal clinical parameters and MMP-8, sICAM-1 in gingival crevicular fluid before and after treatment in two groups were observed and compared, and their efficacy were evaluated. Results The efficiency of group A(minocycline)was 100%,higher than 92.8% in group B(P<0.05).Clinical indicators of periodontal mitigation were alliviate and MMP-8,ICAM content in gingival crevicular fluid were reduced in both two group after treatment (P <0.05 ). Conclusion Minocycline and iodine glycerin have good efficacy in treatment of chronic periodontitis,and minocycline is more better.

Substantia nigra is the largest nuclei in midbrain, which is divided into a compact part and a reticular part. Recent studies have shown that the changes of iron content in reticular part of substantia nigra results in the changes of substantia nigra echogenicity. The substantia nigra detected by transcranial Doppler, according to its echo changes, may provide help for the susceptibility of Parkinson's disease, latency and early diagnosis, as well as for the differential diagnosis of multiple system atrophy and vascular parkinsonism.

Objective To explore the optimal process conditions for cold-soaking extraction of fat-soluble components in Radix Salviae Miltiorrhizae.Methods Tanshione Ⅱwas determined by HPLC.The effect of different concentrations of ethanol and comminution on the extraction rate of tanshione Ⅱwas observed,and the process conditions were optimized by orthogonal test.Results The optimal process conditions for obtaining higher extraction rate of tanshione Ⅱwere as follows: the medicinal material was extracted by cold-soak extraction with 95% ethanol for two times(3 hours for each time),and the volume of ethanol was as much as 8 times of the medicinal material.Conclusion The extraction process is simple,stable and efficient for Radix Salviae Miltiorrhizae.

Objective To investigate the role of hippocampal mu-opioid receptors (MORs) in the formation of seizure susceptibility induced by kainic acid (KA). Methods The SD rats were injected subcutaneously with a convulsive dose of KA (10 mg/kg). Then mini-osmotic pumps were used for intrahippocampal injection with a selective MOR antagonist ?-FNA, and a selective MOR agonist PL017 in these rats. 7 days later, the seizure susceptibility was checked by a subthreshold dose of KA (5 mg/kg). Results All animals showed motor seizures over Stage 4 after a convulsive dose KA injection. 7 days later, 100% animals showed seizures over Stage 4 in KA, CSF + KA and PL017+KA groups after injection of subthreshold dose of KA, but only 28.5% in PL017+KA group. Mean latency of PL017+KA group was (10.1?3.0) minutes, shorter significantly than that of KA and CSF+KA groups (0.010.05). The mean stage of ?-FNA + KA group was 1.7?0.1, being reduced significantly as compared with the stages of other three groups ( P

AIM:To establish the method of fingerprint analysis on Shuangbai Powder(Radix et Rhizoma rhei,Cacumen platycladi,Cortex phellodendri amurensis,Herba lycopi and Herba menthae) to distinguish the characteristic fingerprint.METHODS:HPLC with ZORBAX Eclipse XDB-C18 was used,acetonitrile-0.1% H3PO4 solution(gradient elution) as a mobile phase and detection wavelength at 254 nm,flow rate was 1 mL/min,and column temperature was 40 ℃.RESULTS:Thirty-seven common peaks were separated from 10 batches of Shuangbai Powder.The characteristic peaks were the summation,22 peaks were from Radix et Rhizoma Rhei,6 peaks were from Cortex phellodendri Amurensis,4 peaks were from Cacumen Platycladi,3 peaks were from Herba Lycopi,and 2 peaks were from Herba Menthae,there was one new characteristic peak.CONCLUSION:Ten peaks gathered from Shangbai Powder consist of rhein,emodin,chrysophanol,aloe-emodin,physcion,gallic acid,berberine hydrochloride,palmatine;quercitrosid,and linarin.

Objective:To determine the change in the dietary patterns of Hunan urban residents from1982 to 2012. Methods:A 24 hour dietary recall method was used for 3 consecutive days to collect information on food intake, and the condiment intake was collected by weighting method. Results:Rice products and potato consumption were 449.0 g per person per day and 44.0 g per person per day in 1982, and dropped to 150.0 g per person per day and 9.0 g per person per day in 2012. In 2012, vegetable (277.1 g per person per day), fruits (47.8 g per person per day), milk and dairy products (16.6 g per person per day) consumption were still insuffcient. Fat (59.3 g per person per day) and salt (10.1 g per person per day) consumption was still high. Conlusions:hTe dietary quality of urban residents in Hunan has been greatly improved, but is still seriously imbalanced. To consume more fruits, milk and dairy products and reduce fat and salt intake are very important.
