OBJECTIVE:To study the chief chemical components of the ethyl acetate part of Angelicae Sinensis Decoction for Supplementing Blood Apozem.METHODS:The HPLC was adopted in which Hypersil ODS was taken as the chromato?graphic column,the Methanol-0.5%glacial acetic acid was taken as the mobile phase(gradient elution),the detective wave?length was280nm,the flow rate was1ml/min and with the column temperature set at room temperature.RESULTS:There were7characteristic peaks in the ethyl acetate part of Angelicae Sinensis Decoction for Supplementing Blood Decoction,6of which come from isoflavone of Radix Astragali and1come from ferulic acid of Angelicae Sinensis.CONCLUSION:The chief characteristic peak of the ethyl acetate part of Angelicae Sinensis Decoction for Supplementing Blood Apozem was the building up of Radix Astragali peak and angelicae sinensis peak,no other significant composition peaks were emerged.

OBJECTIVE: To establish the GC fingerprints for Grassleaf sweetflag rhizome aetherolea and to control its quality .METHODS: The temperature at the mouth of the sample injector was 250℃ and that of the detector was 280℃, the carrier gas was nitrogen gas and the flow rate was 1.3ml/min, the GC of aetherolea in 10 batches of Grassleaf sweetflag rhizome was analyzed by adopting temperature programming.RESULTS:Altogether 6 peaks were marked out,the sum total of the average peak area of which made up(75.4?13.7)% of the total.CONCLUSION: The method is of high degree of precision, reproducibility,stability,the resolving of each component in the aetherolea is good,the established fingerprints can be used as one of the quality control index for Grassleaf sweetflag rhizome.

Objective To investigate the expression of an inhibitor gene of apoptosis, clusterin, in prostate cancer and its relationship with the genesis and progression of prostate cancer and with the expressions of bcl 2 and p53. Methods The expressions of clusterin, bcl 2, and p53 in 10 cases of normal prostatic tissues, 15 cases of benign prostatic hyperplasia (BPH), and 49 cases of prostate cancer were examined by immunohistochemical staining. Results The rates of strong positive or weak positive of clusterin in normal prostatic tissues, BPH, and prostate cancer were 10% (1/10), 66.6% (10/15), and 91.8% (45/49), respectively. The expression level of clusterin in prostate cancer tissues was significantly higher than that in normal prostatic tissues ( P

Objective To establish the method of fingerprint analysis on the fruits of Amomum villosum by HPLC and work out the characteristic fingerprint of methanol extracts in the fruits of A.villosum from Yangchun,Guangdong Province as index component which could be used for the accumulation of data to evaluate the inner quality of the fruits of A.villosum.Methods HPLC with Nucleodur C18 Gravity column was used,the methanol-2% acetic acid(gradient elution)as a mobile phase,detection wavelength at 260 nm,column temperature was 30 ℃,and flow rate was 1.0 mL/min.ResultsCommon peaks(20)were separated on HPLC fingerprint in A.villosum.The similarities of 18 batches of samples were higher.Conclusion The method is reliable and accurate,has a better reproducibility,and provides a reference for the quality control to the fruits of A.villosum.

Objective To analyze what will create after oxidation in Shenchang Injection, the oxidated mechanism, and isomerous conversion of ?-asarone and borneol in it. Methods To analyze the sample of Shenchang Injection before and after oxidation by GC-MS and to compare the composition of ?-asarone and borneol before and after sterilization. Results Some of ?-asarone was oxidized and changed to asarylaldehyde (about 0.88%—2.82% of total composition ) and saishinone (about 0.24%—0.46% of total composition), some of the borneol and isoborneol was oxidized and changed to camphor when three samples of Shenchang Injection are oxidized; some of ?-asarone (cis-) change to ?-asarone (trans-, about 1%—2%), (7.85?7.27)% of the isoborneol (cis-) changed to borneol (trans-) when sterilized at 100 ℃ for 30 min. Conclusion ?-Asarone and borneol in Shenchang Injection are involved in the oxidated reaction and have isomerous conversion after high pressure sterilization.

According to the base complementation, the principle antisense technology is the sequence specific binding of complementary antisense nucleic acids or their chemical modification to the nucleic acids in cells, resulting in the suppression or prevention of gene translation. For the treatment of cancer, a lot of antisense drugs have been designed, which target the genes involved in the pathogenesis of cancer. And some of them have been in clinical trials. The author reviewed the progress of the clinical trials of these antisense drugs.

Objective To observe the clinical efficacy of intradermal needle therapy in treating chronic pharyngitis.Method Sixty patients with chronic pharyngitis were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by intradermal needle therapy at Lieque (LU 7) and Zhaohai (KI 6), while the control group was by Compound Borax solution plus Cydiodine Buccal tablets. The symptoms were scored before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 93.3% in the treatment group versus 80.0% in the control group, and the difference was statistically significant (P<0.05). The symptom scores were markedly changed after the treatment in both groups (P<0.01). The symptom score of the treatment group was significantly different from that of the control group (P<0.05). Conclusion Intradermal needle therapy is an effective method in treating chronic pharyngitis.
