〔Abstract〕 The paper introduces the informatization construction status of biobank in Peking University People's Hospital, including construction scope, basic infrastructure, steps as well as informatization management system application status, elaborates the application effect.The informatization construction of biobank could shorten the time of operation and ensure the quality of the samples.

Objective To observe the effect of human immunoglobulin on elderly head and facial post herpetic neuralgia (PHN) and peripheral blood TNF-α.Methods One hundred and twenty-two inpatients with PHN aged ≥65 years old were selected and divided into the observation group (52 cases) and control group (70 cases) by the systematic sampling method.The control group was given the early conventional combined therapy,while on this basis the observation group was intravenously dripped by human immunoglobulin.The incidence rate of PHN and pain visual analog scale(VAS) score at 1,2,3 months after recovery discharge from hospital were recorded in the two groups.Other 20 healthy elderly people were selected as the healthy control group.The TNF-α level was determined in the two patients groups before and after treatment and in the healthy control group.Results The PHN occurrence rate at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group(P＜0.05);the VAS score after treatment and at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group (P＜0.05);serum TNF-α level after treatment in the observation group was significantly lower than that in the control group (P＜0.01),moreover which was close to the level in the healthy control group(P＞0.5).Conclusion Human immunoglobulin can reduce the PHN occurrence in the old people with head and facial herpes zoster and reduce the peripheral blood TNF-α level.

An ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS) method was established for the determination of active components of Sarcandrae Herba, and applied to the pharmacokinetics study of multiple dosage forms. After SD rats were administered by gavage with three dosage forms [Sarcandrae Herba extract, commercial Sarcandrae Herba Guttate Pills, and polydopamine guttate pills loaded with active components of Sarcandrae Herba(PDA-Sg Guttate Pills)], blood samples were collected from the inner canthus at different time points. After protein precipitation, plasma samples were separated on ACQUITY UPLC C_(18) column(2.1 mm×100 mm, 1.7 μm). The mobile phase consisted of water containing 0.2% formic acid and acetonitrile in gradient elution. The negative ions were measured simultaneously in the multi-reaction monitoring(MRM) mode. The pharmacokinetic parameters were calculated and fitted by DAS 2.0. All four components could be detected in the plasma of rats in each group at each time point except the neochlorogenic acid and cryptochlorogenic acid in the Sarcandrae Herba extract group. The guttate pills group showed a significant increase in drug content at each time point. The exposure of the main components of Sarcandrae Herba in blood was effectively increased by PDA-drug loading effect in PDA-Sg Guttate Pills(The AUC_(0-24 h) of neochlorogenic acid, cryptochlorogenic acid, isaziridin and rosmarinic acid reached 2.45, 32.90, 1.54, 4.81 times that of the commercial guttate pills). This study proves the measurability of the above-mentioned multi-component in vitro-in vivo delivery process. The pharmacokinetic study has shown that PDA-Sg Guttate Pills can effectively delay the elimination time and improve the bioavailability of the four components, which can provide theoretical data for the production of the drug.
