To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

OBJECTIVETo observe the therapeutic effects of Berberine Capsule (BC) on patients with mild hyperlipidemia.

METHODSTotally 102 mild hyperlipemia patients were recruited. All patients were suggested to have proper diet and physical activity as basic therapy for 1 month of run-in period. Totally 97 patients completed it. Then they were randomly assigned to the berberine group (the treatment group, 49 cases) and the placebo group (the control group, 48 cases). Patients in the treatment group took BC 300 mg, while those in the control group took placebo 300 mg, thrice per day for 3 successive months. Then placebos and BC were interrupted for 2 months (as washout period). All subjects received only diet control and physical activity during washout period. After washout period, placebos and BC were re-administered to all patients in the same way for 3 months. Body mass index (BMI), fasting plasma glucose (FPG), TG, TC, LDL-C, and HDL-C were assessed after run-in period, washout period, at month 1, 2, 3 after the first therapy, at month 1, 2, 3 after second treatment, respectively.

RESULTSCompared with the end of run-in period, TG, TC, and LDL-C decreased, and HDL-C increased in the treatment group (P < 0.05) after first 3 months of treatment. Compared with 3 months after the first therapy, TG, TC, and LDL-C increased and HDL-C decreased in the treatment group after washout period (P < 0.05). Compared with the end of wash- out period, TC and LDL-C decreased in the treatment group at month 2 after second treatment (P < 0.05); TG, TC, and LDL-C decreased (P < 0.01, P < 0.05), and HDL-C increased (P < 0.05) at month 3 after second treatment. Compared with the control group at month 3 after second treatment, TG, TC, and LDL-C all decreased, and HDL-C increased in the treatment group (all P < 0.05).

CONCLUSIONBC was effective in improving blood lipid level in mild hyperlipidemia patients.

BACKGROUND: It is still a problem to achieve early and accurate diagnosis of Alzheimer's disease, and delayed treatments often occur in a large number of patients because of late diagnosis or misdiagnosis. Therefore, the development and improvement of related bioanalytical methods are of great importance for the biomarker detection of Alzheimer's disease which is still lack of means that are sensitive, efficient and low-cost. OBJECTIVE: To summarize the diagnostic methods and related biomarkers of Alzheimer's disease, and to sum up the research progress in novel biomimetic receptors for the early detection of Alzheimer's disease biomarkers. METHODS: PubMed, CNKI and Wanfang databases were used to search articles related to the biomarker studies of Alzheimer's disease and relevant studies about methods of biomarkers detection published from 2000 to 2016. The key words were "Alzheimer's disease, biomarkers, detect/detecting/detection" in Chinese and English, respectively. Finally 40 articles were obtained for the review. RESULTS AND CONCLUSION: At present, the bioanalytical methods used for biomarker detection of Alzheimer's disease mostly utilize antibodies as recognition and capture elements of biomarkers, but there are some limitations using traditional antibodies as detection receptors. Thus, novel biomimetic receptors can be substituted for conventional antibodies. Novel biomimetic receptors have high specificity, small size, low production costs and high product stability, and their chemical modification process is relatively convenient. Biomimetic receptors developed for protein analysis include aptamers, polypeptide receptors, peptoid receptors, molecularly imprinted polymers, nanobodies, gelsolin and cucurbit urils. Detection of biomarkers with novel biomimetic receptors instead of conventional antibodies will be more accurate and timely in the early diagnosis of Alzheimer's disease.
