OBJECTIVE: To observe the effect of Chaihu on the hepatic cell apoptosis of experimental liver-injured mice and to discuss its mechanism. METHODS: 24 mice were randomly divided into 4 groups : blank control group, model control group, low dosage of Chaihu group and high dosage of Chaihu group, each administered with relevant medications and then killed. The expressions of Bax and Bcl-2 in the hepatic tissue of mice were measured by immunohistochemical method. RESULTS: The expression of Bax in Chaihu treatment group was significantly stronger than that in model control group (P

The author believed that pathogenesis of IGT is yin asthenia,deficiency of both vital energy and yin,obstruct of phlegm and blood stasis,which result from innate deficiency,improper diet,over exertion and so on.According to these pathogenesis,therapeutic principle as supplementing qi and nourishing yin,invigorating vital energy and spleen,removing blood stasis and phlegm,and nourishing yin and kidney are established.Besides,acupuncture and massage have been applied as well.According to the literatures,good potentialities have been shown in traditional Chinese medicine intervening on IGT.

BACKGROUND:The repair and reconstruction of laryngeal structure and function play a crucial role in partial laryngectomy,and the repairing materials and methods have been developed rapidly in recent years.OBJECTIVE:To explore the present application of tissue transplantation on the repair and functional reconstruction after partial laryngectomy,and provide evidences for the selection of repairing materials and reconstructive techniques for laryngeal function.RETRIEVAL STRATEGY:A computer-based search of PubMed database was undertaken to identify the articles of functional reconstruction after partial laryngectomy published from January 1997 to July 2007,with the keywords of "laryngectomy,laryngeal carcinoma/cancer,reconstruction" in English.Simultaneously,Chinese Journal Full-text Database was searched for the relevant articles published between January 2000 and July 2007 with the keywords of "partial laryngectomy,laryngeal carcinoma,repair/reconstruction" in Chinese.Totally 160 relevant articles was retrieved,of which 69 articles were English and 91 articles Chinese.Articles on repair or reconstruction after partial laryngectomy were selected.After the primary filtration,fulltexts of the English articles were checked,and articles on review and with repetitive content were excluded.The articles on clinical research,which were issued in authorized journals,were selected.At last,totally 31 articles were included for review.LITERATURE EVALUTION:Among 31 included articles,16 articles were English and 15 articles Chinese.DATA SYNTHESIS:Functional reconstruction is the key point in course of partial laryngectomy.Technique on repairing postoperative larynx have made a progress,and autologous tissues,such as myofascial flap,flap of strap muscles,myocutaneous flap of neck fascial lata and epiglottis,are extensively used for larynx,which have got good effect.The study of the application of tissue engineering and other variant materials after partial laryngectomy is going on.CONCLUSION:With rapid development of partial laryngectomy,all kinds of repairing materials and reconstruction techniques are used.Repairing postoperative larynx has no fixed mode.It is a very important topic to choose suitable repairing material and reconstruction technique according to different factors such as laryngeal carcinoma type,lesion degree and excision scope,so as to recover the vocalization,respiratory and deglutition function,and raise the patients' survival rate and life quality.

Objective:To analyze and compare pharmacology cognizing between five-year and three-year systems students in medicine to provide materials for teaching innovation.Method:To gather feedbacks from the students and to analyze and induce the cases by EXCEL software.Results:The effectiveness of medicament is the focus.But five-year and three-year systems students concern different problems.57.1% questions raised by three-year system students are about the effectiveness and the effective factors of medicament,while 53.2% by five-year system students are about the effectiveness and the mechanism of medicament.Conclusion: There have been certain differences of pharmacology cognizing between five-year and three-year systems students.

Two cases of labyrinthine ossification were founded in temporal bone exploration and in cochlear implantation. One was caused by temporal bone fracture, the other had bilateral profound sensorineural hearing loss but the reason for labyrinthine ossification was unknown. In this case,unilateral total labyrinthine ossification was not confirmed in preoperative CT scan.

OBJECTIVE:To explore quality control of plasma concentration monitoring for sodium valproate and to improve the quality of pharmaceutical monitoring.METHODS:The statistical and continuous analysis of sodium valproate control data from our hospital of 2008 were conducted using fluorescence polarization immunoassay(FPIA).RESULTS:Mean recovery and RSD were 98.37% and 1.94% for low control samples,99.33% and 2.88% for medium control samples,98.17% and 4.10% for high control samples.The RSD of sample was lower than 5% and in line with the requirement for biological sample determination in Chinese Pharmacopoeia.CONCLUSION:FPIA is a comparatively accurate and stable method for plasma concentration monitoring of sodium valproate.

Objective:To establish an HPLC method for the simultaneous determination of viceninⅡ, isoschaftoside and schafto-side in Isodon lophanthoides, and analyze their content dynamic changes. Methods:The HPLC system consisted of a Phenomenex luna C18(250 mm ×4.6 mm, 5 μm)column and a solution system of methanol and 0.5% formic acid with gradient elution, the flow rate was 0. 8 ml·min-1 and the detection wavelength was 334 nm at the column temperature of 25℃and the injection volume was 10 μl. Results:The linear range of viceninⅡ, isoschaftoside and schaftoside was 0.130-3.110 μg(r =0.999 8), 0.180-4.540 μg(r =0.999 9) and 0.080-1.970 μg(r =0. 9999), respectively. The average recovery was 96.8% (RSD =1.9%), 99.2% (RSD =1. 6%) and 97. 1% (RSD=1. 6%) (n=6), respectively. The above three kinds of water-soluble flavonoids from seedling stage to significant accumulation, isoschaftoside and schaftoside reached the highest value in March and August, the content of VitexinⅡ in January and April tends to be stable, in May began to increase gradually, reached the maximum value in August, then began to de-crease. Conclusion:With the contents of water-soluble flavonoids as the indicators, the best harvest time of Isodon lophanthoides is March and August, and the quality of the medicinal materials harvested in August is the best.

Objective To investigate the optimal time points for transplantation with in vitro cultured dopaminergic neurons as a potential treatment of Parkinson’s disease. Methods After the ventral mesencephalic precursors from E11 rat embryos were expanded for 7 days in vitro, they were harvested respectively from day 0 to day 7 in the period of induced differentiation. Then the cells were seeded again and cultured for another 7 days. The final survival of dopaminergic neurons determined the optimal time points for moving cells in vitro and, possibly, for transplantation in vivo. Result The survival rate of dopaminergic neurons moved on day 0 and day 1 in the period of induced differentiation was significantly higher than that at other time points. Conclusion The optimal time points for transplantation are found possibly to be day 0 and day 1 in the period of differentiation after the expansion of ventral mesencephalic precursors from E11 rat embryos.
