[HPLC fingerprints of pig, cattle and sheep biles].

To establish the fingerprints of biles of pig, cattle and sheep, HPLC was used with Acclaim™ RSLC 120 C18 column (3.0 mm×100 mm, 2.2 µm, 120 Å), the column temperature 35 °C, acetonitrile-1% perchloric acid as mobile phase, gradient elution, 0.5 mL·min⁻¹ flow rate, and detection wavelength at 200 nm. The fingerprint was generated by using Similarity Evaluation Software of Chromatographic Fingerprint of Chinese Medicine (2004A Edition). The fingerprint peaks were identified by reference substances and verified by ELSD and LC-MS/MS. Then, the biles of pig, cattle and sheep were detected to contain 14, 9 and 8 common fingerprint peaks respectively, and the similarity was greater than 0.92. To analyze each technical parameter, GHDCA in pig bile and TCA in cattle and sheep bile were selected as reference peak. The precision, repeatability and stability all meet the requirements of fingerprint establishment. The RSD of the relative retention time of the fingerprint peaks was less than 1.5%, and the RSD of the relative peak area was less than 5%. The fingerprint peaks in pig bile were THDCA, TCDCA, GHDCA and GCDCA, and TCA, TCDCA, GCA, GCDCA and GDCA in cattle and sheep bile. The main components of pig, cattle and sheep bile were conjugated bile acids, but there were significant differences in bile acids between pig bile and cattle, sheep biles. The HPLC method established in this paper is simple, rapid and reproducible, and could be applied to the identification and quality control of biles.

[Design and implementation of data checking system for Chinese materia medica resources survey].

The Chinese material medica resources (CMMR) national survey information management system has collected a large amount of data. To help dealing with data recheck, reduce the work of inside, improve the recheck of survey data from provincial and county level, National Resource Center for Chinese Materia Medical has designed a data checking system for Chinese material medica resources survey based on J2EE technology, Java language, Oracle data base in accordance with the SOA framework. It includes single data check, check score, content manage, check the survey data census data with manual checking and automatic checking about census implementation plan, key research information, general survey information, cultivation of medicinal materials information, germplasm resources information the medicine information, market research information, traditional knowledge information, specimen information of this 9 aspects 20 class 175 indicators in two aspects of the quantity and quality. The established system assists in the completion of the data consistency and accuracy, pushes the county survey team timely to complete the data entry arrangement work, so as to improve the integrity, consistency and accuracy of the survey data, and ensure effective and available data, which lay a foundation for providing accurate data support for national survey of the Chinese material medica resources (CMMR) results summary, and displaying results and sharing.

[Effect of Xianlong granules on immunological function in rats of adjuvant arthritis].

OBJECTIVE: To study the effect of Xianlong granules (XLG) on immunological function in the rat of adjuvant arthritis (AA). METHOD: Rats were randomly divided into normal group, AA model group, prednisone group and low, middle and high dose XLG groups, 10 rats in each group. All rats were treated by intragastric administration from the 18 days after arthritis was induced by the complete Freud's adjuvant and the effect of XLG on toes swelling was observed. On the 30th days after modeling, proliferation of the splenic and thymic lymphocytes, and IgG secreted by splenocytes were detected respectively by MTT assay and ELISA. RESULT: Compared with the model group, both the high and middle dose XLG groups had significant therapeutic effects on toes dwelling in the rat of AA (P < 0.05 or P < 0.01); The low, middle and high dose XLG groups strengthened the PHAM-inhibited proliferation of splenic lymphocytes (P < 0.05), and inhibited the PHAM-augmented proliferation of thymic lymphocytes (P < 0.05); XLG did not significantly effect on IgG level secreted by splenocytes in rats of AA. CONCLUSION: XLG can cure toes swelling in rats of AA, which is related with regulation of the abnormal immunlological function.

[Ocular deviation as the cause of "psychiatric" problems]. / Onderliggende oogaandoening als oorzaak van psychiatrisch geduide klachten.

We describe two cases with complaints of atypical headache who were initially diagnosed as having psychiatric problems, but who, after careful evaluation, were found to have an underlying eye disorder. Both patients were known to have an ophthalmic history. Patient A, a 21-year-old female, presented with severe headache, which was so disabling that she was declared unfit for work. A diagnosis of tension headache was made and she received psychological treatment with neurofeedback, homeopathy and acupuncture, which had no effect. Patient B, a 26-year-old male, complained of extreme photophobia, nausea and dizziness. The patient was diagnosed as having a conversion disorder and was admitted to a psychiatric clinic and given psychotropic treatment. Careful ophthalmological examination revealed that an ocular deviation was causing the symptoms in both patients and could be treated appropriately with strabismus surgery. These cases emphasise the importance of a thorough general medical and ophthalmic history and proper examination at all times without putting a psychiatric stigma on the patient.

Safety and tolerability of a single dose T0001 in Chinese healthy adult volunteers: a first-in-human ascending dose study

T0001 is the first mutant of etanercept with a higher affinity to tumor necrosis factor α (TNF-α) than etanercept. In order to investigate the safety and tolerability of T0001, a study was carried out in healthy Chinese subjects. A first-in-human, dose escalation study was conducted in healthy Chinese subjects. Fifty-six subjects were divided into six dose cohorts (10 mg, 20 mg, 35 mg, 50 mg, 65 mg and 75 mg) to receive a single subcutaneous injection of T0001. Safety and tolerability assessment were based on the records of vital signs, physical examinations, clinical laboratory tests, 12-lead electrocardiograms and adverse events (AEs). All subjects were in good compliance and none withdraw due to AEs. No serious AEs occurred. A total of twenty-three AEs in sixteen subjects were recorded, and eighteen of these AEs were believed to be related to T0001. The most frequently reported AEs were injection site reactions and white blood cell count increase. All these AEs were of mild to moderate intensity and most of them recovered spontaneously within 14 days. In this study, no dose-limiting toxicity was observed, and the maximum tolerated dose was identified as 75 mg. T0001 was considered safe and generally well tolerated at doses up to 75 mg in healthy Chinese volunteers
