Physiologically based pharmacokinetic model (PBPK), a mechanistic mathematic model, which can simulate the absorption, distribution, metabolism and excretion of drugs, is being more widely used in pharmaceutical research and development areas. This article reviews primarily the recent advances in the procedure of establishing a PBPK model, including specifying of the PBPK model structure, specification of the tissue model, writing of equations, set of model parameters, simulation and evaluation. Application significance, major challenges and future developments of PBPK model in pharmaceutical areas are also discussed.

Objective Investigation and analysis of intelligence and psychomotor function in children born after implementingt universal salt iodization(USI). Methods Historical serious illness areas of water iodine below 10μg/L were selected as study sites, water iodine in 50 - 100 μg/L in the historical non-endemic areas were as control points in Henan, 2008. Cluster sampling was used to select children aged 6 - 15 years as observing subjects,IQ were measured with CRT- Man Test(CRT-C2). A "Tianjin Medical psychomotor test battery" (JPB) was carry out to test psychomotor function. Results In IDD regions 230 children were surveyed post-USI and 1284 children preUSI. The IQs post and pre USI were 99.3 and 99.9, respectively, and the proportion of IQ ≤69 were 2.17%(6/230) and 2.80%(36/1284), respectively. In non-IDD regions 650 children were surveyed post-USI and 2079children pre-USI. The IQs post and pre USI were 95.3 and 93.8, respectively, and the proportion of IQ ≤ 69 were 2.31%(15/650) and 3.37%(70/2079), respectively. In IDD regions, the abnormal rate of T scores and damage index post USI were 3.6%(2/56), 5.3%(3/56), respectively, significantly lower than pre USI [18.1%(29/160),18.1%(29/160), x2 = 7.54, 6.86, all P ＜ 0.01]. Conclusions USI could increase the IQs of children and decrease the positive rate of JPB, and significantly improve the quality of whole nation and persistently eliminating IDD.

By studying the varieties of peony and analyzing the prescription of Huangqin decoction, the authors explored the differences between Paeoniae Radix Alba and Radix Paeoniae Rubra in varieties, origin, processing method and clinical efficacy and compare their efficacies to define Paeoniae Radix Alba or Paeoniae Radix Rubra in Huangqin decoction recorded in Treatise on Febrile Diseases. In the study, the authors clarified the development and change of the variety in various historical periods according to the earliest ancient herbal book recording the variety and the development sequence of main herbs, and made clear the relations between Paeoniae Radix Alba and Paeoniae Radix Rubra. The modern application of Paeoniae Radix Alba started in the Song Dynasty. Although it was processed in different ways from Paeoniae radix Rubra, they shared the same original plant varieties. On the basis of the historical origin, botanical origin, producing place and processing method, the authors made clear the evolvement of peony varieties, discussed and analyzed the developments and changes for the combined to the separate administration of Paeoniae Radix Alba and Paeoniae Radix Rubra and defined the peony variety in Huangqin decoction. Through the textual research on ancient herbal books, the authors confirmed that more than 2 000 years ago, Paeoniae Radix Alba didn't appear when Treatise on Febrile Diseases was written. According to the records in Miscellaneous Records of Famous Physicians that "its roots were collected and dried in February and August", it was inferred that the use of Paeoniae Radix Rubra conformed to the historical facts.

Objective To analyze the characters about anticoagulation EDTA on the platelet aggregation ,and discuss the risk factors about EDTA‐PTCP by analyzing the biochemical parameters .Methods 30 700 EDTA‐K3 blood samples were collected from January 2014 to August 2015 .WBC was performed using Sysmex XN‐3000 and 27cases were identified of EDTA‐PTCP .The blood samples of 27 subjects were recollected and WBC was repeated using EDTA‐K3 and sodium citrate blood ,respectively .Manual platelet counting and smear microscope examination on periphery blood were also performed .Biochemical parameters of 27 subjects with EDTA‐PTCP were compared with 50 randomly selected non EDTA‐PTCP controls .Results Platelet counts in citrated blood were significantly higher than EDTA blood ,the difference was statistically significant(P< 0 .05) ,but similar to manual platelet counting(P>0 .05) .ALT ,Glu and TG in patients with EDTA‐PTCP were significantly higher than normal people ,but HDL was significantly lower than control group ,the difference was statistically significant(P<0 .05) .Conclusion EDTA‐dependent pseudo‐thrombocytopenia varies from people with different disease or using different medicine .It may be relative to hyperglycemia and hy‐perlipidemia .Another approach for rectifying ,changing anticoagulant or manual platelet counting is a better way lead to correctly di‐agnose when EDTA‐PTCP occurred .
