Objective To understand the sanitary quality of cosmetics in Wuhan. Methods The sanitary quality of cosmetics including hair care cosmetics, skin care cosmetics, beauty cosmetics, perfumes and cosmetics for special use sampled from 23 cosmetics manufactures and 15 large-scale whole-salers and retail traders in Wuhan were examined during 1996～2001. Results The annual qualified rates of cosmetics were 93.49%～98.69% in 1996～2000. It was 95.65% for hair care cosmetics, 92.41% for skin care cosmetics, 98.13% for beauty cosmetics, 100% for purfumes and 95.56% for special use cosmetics respectively. They also were 93.62%～98.69% for microbiological indexes and 99.17%～100% for chemical indexes respectively. The total count of bacteria of skin care cosmetics seriously exceeded the related sanitary standard. Conclusion The main problem of the sanitary quality of cosmetics was the microbiological pollution.

Objective To investigate the effects of minimally invasive intracranial hematoma clearance on the perihematomal glutamate(Glu) level,permeability of blood-brain barrier(BBB) and brain edema.Methods Thirty rabbits with body weight of 2.80-3.40 kg were used to established the model of spontaneous intracerebral hemorrhage(ICH) and randomly divided into the minimally invasive group(MI) and control group(MC) after the model was prepared successfully.The MI group underwent minimally invasive procedures for removing intracranial hematoma by stereotactic instrument within 6 h after establishing the ICH model.The brain tissue was extracted on postoperative 1,3,7 d,and the perihematomal brain tissues were taken to detect the Glu level,BBB permeability and water content of brain tissue,which were compared with those in the control group.Results The Glu level,BBB permeability and brain water content on 1,3,7 d in the MI group were lower than those in the MC group,and the differences were statistically significant(P＜0.05).Conclusion The minimally invasive surgery for removing intracranial hematoma is helpful to reduce perihematoma Glu level,BBB permeability and brain water content.

To investigate the protective effect of retinoic acid (RA) on hyperoxic lung injury and the role of RA as a modulator on mitogen-activated protein kinases (MAPKs), gastation 21 d Sprague-Dawley (SD) fetuses (term = 22 d) were delivered by hysterotomy. Within 12-24 h of birth, premature rat pups were randomly divided into 4 groups (n=12 each): air-exposed control group (group I); hyperoxia-exposed group (group II), air-exposed plus RA group (group III), hyperoxia-exposed plus RA group (group IV). Group I, III were kept in room air, and group II, IV were placed in 85 % oxygen. The pups in groups III and IV were intraperitoneally injected with RA (500 microg/kg every day). All lung tissues of premature rat pups were collected at the 4th day after birth. Terminal transferase d-UTP nick end labeling (TUNEL) staining was used for the detection of cell apoptosis. The expression of PCNA was immunohistochemically detected. Western blot analysis was employed for the determination of phosphorylated and total nonphosphorylated ERKs, JNKs or p38. Our results showed that lungs from the pups exposed to hyperoxia for 4 d exhibited TUNEL-positive nuclei increased markedly throughout the parenchyma (P<0.01), and decreased significantly after RA treatment (P<0.01). The index of PCNA-positive cells was significantly decreased (P<0.01), and was significantly increased by RA treatment (P<0.01). The air-space size was significantly enlarged, secondary crests were markedly decreased in hyperoxia-exposed animals. RA treatment improved lung air spaces and secondary crests in air-exposed pups, but had no effect on hyperoxia-exposure pups. Western blotting showed that the amounts of JNK, p38 and ERK proteins in hyperoxia-exposure or RA-treated lung tissues were same as those in untreated lung tissues (P>0.05), whereas activation of these MAPKs was markedly altered by hyperoxia and RA. After hyperoxia exposure, p-ERK1/2, p-JNK1/2 and p-p38 were dramatically increased (P<0.01), whereas p-JNK1/2 and p-p38 were markedly declined and p-ERK1/2 was further elevated by RA treatment (P<0.01). It is concluded that RA could decrease cell apoptosis and stimulate cell proliferation under hyperoxic condition. The protection of RA on hyperoxia-induced lung injury was related to the regulation of MAP kinase activation.

Objective To investigate the role of signal transduction of toll-like receptors(TLRs)in immunological pathogenesis in children with acute idiopathic thrombocytopenic purpura(ITP).Methods Thirty children with actue ITP and 30 age-matched healthy children were studied.Real-time fluorescent quantitative PCR was used to evaluate the levels of TLR 1-10 and signal transducing molecules,and cytokines associated with TLRs,such as IL-1?,granulocyte-macrophage colony-stimulating factor(GM-CSF),macrophage colony-stimulating factor(M-CSF)and IFN-?/? mRNA.Expressions of co-stimulatory molecules such as CD40,CD80 and CD86 in mo-nocyte/macrophage(MC)was analyzed by flow cytometry.Results Compared with healthy control group,the mRNA levels of TLR3,7,8 and 9 in ITP group were significantly up-regulated(Pa0.05).Transcription le-vels of MyD88-dependent and-independent pathway molecules such as MD-2,MyD88,IRAK-4,TRAF6,TAK1,TRIF,TRAM,TBK-1 and IFN-? were significantly up-regulated in acute ITP(Pa0.05).Conclusion Aberrant activation of toll-like receptors signaling may be one of the initiating factors of immune dysfunction in children with acute ITP.

The study aimed to establish a population pharmacokinetic/pharmacodynamic (PPK/PD) model of warfarin. PCR-RFLP technique was used to genotype the CYP2C9 and VKORC1 polymorphisms of 73 patients. RP-HPLC-UV method was used to determine the 190 plasma concentrations of warfarin. Application of NONMEM, the clinical information and 263 international normalized ratio (INR) monitoring data were used to investigate the effect of genetic, physiological, pathological factors, other medication on clearance and anticoagulant response. The final model of warfarin PPK/PD was described as follows: CL = θCL · (WT/60)θWT · θCYP · eηCL (if CYP2C9*1/*1, θCYP = 1; if *1/*3, θCYP = 0.708); EC50 = θEC50 · θVKOR · eηEC50 (if VKORC1- 1639AA, θVKOR = 1; if GA, θVKOR = 2.01; V = θV; K(E0) = θK(E0); Emax = θEmax; E0 = θE0 · eηE0. Among them, the body weight (WT), CYP2C9 and VKORC1 genotype had conspicuous effect on warfarin PK/PD parameters. The goodness diagnosis, Bootstrap, NPDE verification showed that the final model was stable, effective and predictable. It may provide a reference for opitimizing the dose regimen of warfarin.
