Objective To investigate the postmortem redistrib ution of morphine in rat model of chronic morphine poisoning. Methods Samples including cardiac blood, liver, heart, kidney, lung and brain tissues were collected in the rats with chronic morphine poisoning at 0～96 h after death, respectively. The morphine amount was measured with solid phase ext raction-gas chromatography. Results The study showed an increase in morphine concentrat ion of postmortem cardiac blood. Significant increase in morphine level was also observed 24～96 h after death in liver, heart and brain tissues, while the kid ney morphine levels decreased at 96 h after death. In the liver there was the g reatest increase (25-fold) in morphine levels 96 h after death. All the sample s showed marked alterations in morphine concentration within 96 h after death c ompared with cardiac blood at time of death. The postmortem morphine levels in b rain were closely related to those in the heart blood. Conclusion The postmortem redistribution of morphine exists in rats with chronic morphine poisoning. The brain tissues may better represent morphine levels in heart blood at the time of death.

Objective To investigate the effects of paravertebral injection of different concentrations of adriamycin on motor conduction function in rats. Methods Eighty healthy male Wistar rats weighing 250-300 gwere randomly divided into 4 groups (n = 20 each): 3 adriamycin groups receiving paravertebral injection of 0.3%, 0.5% and 1.0% adriamycin 10 μl respectively (group A1, A2, A3) and control group (group C)receiving equal volume of normal saline (NS) instead of adriamycin. The animals were anesthetized with intraperitoneal 3% pentobarbital 40 mg/kg. A right paramedian incision was made in the back from L3 to S1.L4,5,5,6 intervertebral foramina were exposed. 0.3%, 0.5% and 1.0% adriamycin and NS 10 pl were injected into the intervertebral foramina in group A1, A2, A3 and C respectively. Spinal motor evoked pontential (SMEP)was measured at 1, 2, 4 and 8 weeks (T1-4)after paravertebral injection. Results The latent period of SMEP was significantly prolonged and the amplitude decreased at T1-4 in group A3 as compared with group A1, A2 and C.Conclusion Paravertebral injection of 1.0% adriamycin can significantly depress motor conduction function.

Objective To establish a method for the determination of serum potassium using isotope dilution inductively coupled plasma mass spectrometry.Methods Frozen human serum pools of different potassium concentrations were prepared from healthy donors of Chao-yang Hospital laboratory in 2010 Serum samples were diluted with 1％ HNO3 supplemented with 41K spike and isotope ratio was measured after selection and optimization of ICP-MS analysis conditions.Serum 39K concentrations were calculated by interpolation method.3 different serum samples were used to evaluate the precision of the method.Standard Reference Material 909b Ⅰ and Ⅱ of National Institute of Standards and Technology were used to evaluate the accuracy.The recovery was evaluated through 2 serum samples added standard material for potassium,uncertainty was calculated.Results The analytical precision of serum potassium measurement was 0.14％ to 0.11％.The results of SRM909b Ⅰ and Ⅱ gave the coefficients of variation (CVs) of 0.39％ to 0.32％.Data was consistent with the certified value and the CV was + 0.12％ and + 0.49％ respectively.The recovery was 99.68％ to 100.12％ for 2 different serum samples.Conclusions ID-ICP-MS method was successfully established to measure the serum potassium concerntration precisely and accurately,it is an ideal method for the accurate determination of inorganic elements.

Objective To understand the global economic burden of diseases due to needle stick injuries(NSIs), obtain relevant evidence,and prompt the relevant departments to pay attention to the precaution of NSIs.Methods Literatures about NSIs published from 1990 to May 2016 were searched from PubMed,ScienceDirect,EBSCO-host,Cochrane,CNKI,and Wanfang database.According to world bank inflation rate and currency rate in 2015, cost of needle stick injury in each study was adjusted to US dollars in December 2015,merge comparison analysis was performed.Results A total of 7 literatures were included,3 American studies and 4 studies from Sweden,Ko-rea,Belgium,and Taiwan Region of China respectively.Studies in mainland China only focused on the incidence of NSIs,studies about cost were not found.Two studies did not identify studied population,the remaining 5 studies were about all staff in the medical institutions.Cost analysis method:Of 7 literatures,3 were first-hand data analy-sis,4 were derived from the model.Scope of cost research:4 studies estimated the direct cost,2 calculated direct and indirect cost respectively,only 1 study estimated the summation of direct and indirect cost.The total cost per inj ury (direct cost + indirect cost)was $747-$2173,direct and indirect cost were $167-$617 and $322-$455 respectively.Conclusion Global economic burden of NSIs is heavy and still undervalued;NSIs occur frequently in China,but attention is inadequate,research on economic burden is lacking,relevant departments should pay atten-tion to the prevention and follow-up treatment process of NSIs.

Objective To investigate differences in Rab protein expressions in McCoy cells with acute versus persistent Chlamydia trachomatis (Ct) infection.Methods Cultured McCoy cells were infected with different amounts (400,500,550 μl/well) of Ct strain D suspensions,then cultured with the medium containing 100 U/ml penicillin G (persistent Ct infection groups) or that without penicillin G (acute Ct infection groups).Ct-uninfected McCoy cells receiving no penicillin G treatment served as the blank control group,and those receiving penicillin G treatment as the penicillin group.Mter 48-hour culture,McCoy cells were lysed,proteins were collected,and total RNA was extracted from the cells.Enzyme-linked immunosorbent assay (ELISA) was conducted to measure protein levels of Rab4A,Rab6A,Rab10,Rab11A and Rab14,and fluorescence-based quantitative PCR to quantify mRNA expressions of Rab4A and Rab14 (expressed as 2-ΔΔα).Results Protein levels of Rab4A,Rab6A,Rab10,Rab11A and Rab14 were all significantly lower in the acute than in the persistent Ct infection groups (all Z =3.621,P ＜ 0.001),and lower in the persistent and acute Ct infection groups than in the blank control group (all P ＜ 0.008 3),but insignificantly different between the blank control group and penicillin group (all P ＞ 0.05).In addition,the expressions of Rab4A and Rab14 mRNAs were consistent with those of their proteins in these groups.Conclusion The transcriptional and expression levels of Rab proteins are higher in McCoy cells persistently infected with Ct than in those acutely infected with Ct.
