Objective: To establish the quality standard of Fushukang Granules (Radix Astragali, Radix Angelicae sinensis, Rhizoma Chuanxiong, Radix Paeoniae Alba, etc.). Methods: TLC was used in qualitative identification of the Radix Astragali, Radix Angelicae Sinensis, Rhizoma Chuanxiong, Radix Paeoniase Alba. And TLC-scanning was used for assay of astragaloside I in the preparation. Results: Radix Astragali, Radix Angelicae Sinensis, Rhizoma Chuanxiong, Radix Paeoniae Alba could be detected by TLC. Astragaloside I had a good linear relationship within the range of 1.001～5.005?g(r=0.9998). The average recovery was 92.46%, and the RSD was 2.82%, respectively. Conclusion: The method established is stable and reliable. It can be used for quality control of the preparation.

OBJECTIVE: To evaluate the clinical value of lidocain in the treatment of tinnitus through three routes of administration (intravenous, intratympanic and acupoint injection) by analyzing literatures. METHOD: Articles were collected through Hownet, Wanfang, VIP, Pubmed, SciVerse ScienceDirect, Springer and OVID, etc. The articles were strictly evaluated based on their quality. The Meta-analysis was performed to evaluate the outcomes by RevMan 5. 2 software. RESULT: A total of 16 articles with 1203 patients were enrolled in the analysis. Their tinnitus history ranged from 7 hours to 20 years. Assessment methods include tinnitus loudness levels, severity scales and subjective feelings. None of articles refer to maintaining time, instead of "short-term", "short" and so on. A total of 133 cases received intravenous injection and the effective rate was 73.4% (98 cases). 50 cases and 332 cases received intratympanic and acupoint injection respectively and their effective rates were 74.0% and 87.7%, respectively. The effective rate ranged from 42.4% to 58.3% in control group. Meta-analysis results indicate that all three routes of lidocaine administrations are more effective than conventional methods (P < 0.05). CONCLUSION Different routes of lidocaine administration have a good but short time effects on the tinnitus control. It can effectively reduce the time of tinnitus habituation as a complementary treatment. But its value still needs further evaluation.

Objective To observe the effects of electro-acupuncture and functional training on gross motor function of children with cerebral palsy. Methods 137 children with cerebral palsy were divided into observation group (n=81) and control group (n=56). The observation group received electro-acupuncture and functional training, and the control group received functional training only. Results The scores of Gross Motor Function Measure (GMFM) increased in both group after treatment (P<0.01), and it was significantly higher in the observation group than in the control group (P<0.01). Conclusion Electro-acupuncture and functional training is superior to functional training in gross motor function.

OBJECTIVETo develop a method for determination of 2, 4-dichlorophenoxyacetic acid (2, 4-D) in the air of workplace by high-performance liquid chromatography.

METHODS2, 4-D was collected by ultrafine glass filters, desorbed by methanol, separated by a C18 column, and detected by a UV detector. Identification and quantification of 2, 4-D were performed by retention time and peak areas, respectively.

RESULTSThe linear range of the test was 2∼200 µg/ml; the elution efficiency was 94.6%- 95.9%; the limit of detection (S/N = 3) was 0.034 µg/ml (injection volume of 20 µl eluant); the lower limit of quantification (S/N = 10) was 0.11 µg/ml; the minimum detectable concentration was 0.011 mg/m(3); the minimum quantifiable concentration was 0.037 mg/m(3) (with sampled air volume of 45 L).

CONCLUSIONThis method is convenient and simple in sample collection and preparation, and satisfies all methodological requirements. Therefore, this method is useful for the determination of 2, 4-D in the air of workplace.
