Objective:To establish a high performance size-exclusion chromatography ( HPSEC) method for the determination of impurities including polymers in latamoxef sodium. Methods:The analysis was performed on a Zenix SEC-150 column(7. 8 mm × 300 mm, 3 μm)with the mobile phase of 0. 005 mol·L-1 phosphate buffer solution [0. 005 mol·L-1 disodium hydrogen phosphate-0. 005 mol·L-1 sodium dihydrogen phosphate (61∶39), pH 7. 0] at a flow rate of 0. 8 ml·min-1. The detection wavelength was set at 254 nm. The column tempretrue was 25℃ and the injection volume was 10μl. Results:The impurities including polymers in latamoxef so-dium were completely separated from latamoxef. The linear range of latamoxef was 0. 98-97. 73 μg·ml-1(r=0. 999 9). The limit of quantitation of latamoxef was 2. 9 ng, and the detection limit was 1. 0 ng. The linear range of the total impurities was 0. 45-2. 8 mg· ml-1(r=0. 999 5). Conclusion: The established method is accurate, rapid and reproducible, and suitable for the determination of impurities including polymers in latamoxef sodium.

OBJECTIVETo compare the difference in the clinical efficacy on perennial allergic rhinitis between three nasal points acupuncture therapy and the oral administration of loratadine so as to provide the better acupuncture program in clinical treatment.

METHODSSixty cases were randomized into an acupuncture group (30 cases) and a medication group (30 cases). In the acupuncture group, acupuncture was applied to three nasal points [Yingxiang (LI 20), Yintang (EX-HN 3), Bitong (Extra)] and acupoints selected by syndrome differentiation. Acupuncture was given once every two days, three times a week, for 4 weeks totally. In the medication group, loratadine was prescribed for oral administration, 10 mg every day, for 4 weeks. The symptom and physical sign scores before and after treatment, as well the short-term and long-term efficacy were compared between the two groups.

RESULTSThe total effective rate was 96.7% (29/30) in the acupuncture group and was 93.3% (28/30) in the medication group after treatment. The efficacy was similar between the two groups (P>0.05). In follow-up, the total effective rate was 86.7% (26/30) in the acupuncture group, which was better than 56.7% (17/30, P<0.05) in the medication group. The scores of symptoms and physical signs after treatment and in follow-up were all reduced apparently as compared with those before treatment in the patients of the two groups (all P<0.05). The scores of symptoms and physical signs were reduced more apparently in the acupuncture group as compared with those in the medication group in follow-up (all P<0.05).

CONCLUSIONThe acupuncture at three nasal points and the acupoints selected by syndrome differentiation achieves the similar short-term efficacy on perennial allergic rhinitis as compared with the oral administration of loratadine. The acupuncture therapy presents the obvious advantages on long-term efficacy.
