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.

BACKGROUND: Cardiopulmonary resuscitation (CPR) is a kind of emergency treatment for cardiopulmonary arrest, and chest compression is the most important and necessary part of CPR. The American Heart Association published the new Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care in 2010 and demanded for better performance of chest compression practice, especially in compression depth and rate. The current study was to explore the relationship of quality indexes of chest compression and to identify the key points in chest compression training and practice.METHODS: Totally 219 healthcare workers accepted chest compression training by using Laerdal ACLS advanced life support resuscitation model. The quality indexes of chest compression, including compression hands placement, compression rate, compression depth, and chest wall recoil as well as self-reported fatigue time were monitored by the Laerdal Computer Skills and Reporting System.RESULTS: The quality of chest compression was related to the gender of the compressor. The indexes in males, including self-reported fatigue time, the accuracy of compression depth and the compression rate, the accuracy of compression rate, were higher than those in females. However, the accuracy of chest recoil was higher in females than in males. The quality indexes of chest compression were correlated with each other. The self-reported fatigue time was related to all the indexes except the compression rate.CONCLUSION: It is necessary to offer CPR training courses regularly. In clinical practice, it might be better to change the practitioner before fatigue, especially for females or weak practitioners. In training projects, more attention should be paid to the control of compression rate, in order to delay the fatigue, guarantee enough compression depth and improve the quality of chest compression.

Background Age-related cataract is one of the common causes of blindness.Although the pathophysiology of age-related cataract is far from clearly understood,it is well accepted that DNA damage plays an important role in the disease pathogenesis.Objective The purpose of this study was to quantitatively evaluate the DNA damage in peripheral lymphocytes of age-related cataract.Methods A cross-sectional study was carried out.This study complied Declaration of Helsinki and approved by Ethic Committee of Affiliated Hospital of Nantong University.Written informed consent was obtained from each subject.Two hundred and eleven patients with agerelated cataract and 147 normal subjects were enrolled from a “ Jiangsu Eye Study:Funing 2011 Eye Disease Epidemic Survey”.All the subjects aged from 50 through 80 years with matched age and gender between the two groups.The percentage of tail DNA and Olive tail moment (OTM) were detected by comet assay to assess the extent of DNA damage in peripheral lymphocytes.Statistical analyses were performed with SPSS 17.0 software,and the differences of the percentage of tail DNA and OTM were compared between the age-related cataract group and normal control group by independent sample t test as well as among the 50-59 years group,60-69 years group and ≥70 years group by one-way analysis of variance.Results Comet assay showed a round lymph cell with the clear border in the normal group;while in the age-related cataract group,the cell was bigger with a comet-like tail.The percentage of tail DNA and OTM in peripheral lymphocytes were (21.75 ± 3.51) ％ and 6.54 ± 1.65 in the age-related cataract group,and those in the normal control group were (9.31 ±3.60)％ and 2.18 ± 1.10,respectively,with significant differences between them (t =32.67,P =0.00 ; t =28.02,P =O.00).In the 50-59 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.04±2.86) ％ and 5.92± 1.14,and in the 60-69 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.77 ±2.93) ％ and 6.13 ± 1.14,which were significantly reduced in comparison with (22.79 ± 3.67)％ and 6.95±1.91 of the ≥70years subgroup(TailDNA％:q=2.75,P=0.00; q=2.02,P=0.00;OTM:q=1.03,P =0.02 ; q =0.82,P =0.00).Conclusions The pathogenesis and development of age-related cataract probably is associated with DNA damage.

OBJECTIVETo investigate the impact of treatment modality and clinicopathologic profile on prognosis in primary fallopian tube carcinoma.

METHODSThe data of 64 cases with primary fallopian tube carcinoma treated between January 1991 and June 2006 were analyzed. The clinicopathological data were retrospectively analyzed.

RESULTSThe overall 5-year survival rate of this series was 56.3%. The overall 3- and 5-year survival rate was 84.6% and 65.4% in surgical staging group versus 58.3% and 33.3% in no surgical staging group with a significant difference between two groups (P = 0.0429; P = 0.043), which was 89.5% and 68.4% in optimal cytoreduction group versus 66.7% and 41.7% in suboptimal cytoreduction group (P = 0.0466; P = 0.0444). However, there was no significant difference in 3-year and 5-year survival rate between the group with pelvic lymphadenectomy and the group without (84.2% vs. 69.2%, P = 0.4667; 63.1% vs. 53.8%, P = 0.459), and also between the group treated using CAP/CP regimen and the group by TP regimen for chemotherapy (81.8% vs. 80.0%, P = 0.8946; 59.1% vs. 60.0% P = 0.9582). It was found that the 5-year survival was correlated with FIGO stage (III-IV vs. I - II, P = 0.0197), differentiation grade (G3 vs. G1 + G2, P = 0.003), pathologic type (other type vs. serous, P = 0.0494), lymph nodes status (positive vs. negative, P = 0.0295).

CONCLUSIONSurgical staging, optimal cytoreduction, differentiation grade, pathologic type, lymph node status are important factors influencing the 5-year survival in primary fallopian tube carcinoma. Pelvic lymphadenectomy is necessary and feasible to perform during the procedure of surgical staging and cytoreduction. CAP/CP and TP regiment are similarly effective in adjuvant chemotherapy for primary fallopian tube carcinoma.

Objective To investigate the changes in the prescriptions of antidepressants for inpatients with psychosis from 2005 to 2008. Methods The prescriptions of antidepressants for all the inpatients with psychosis in Shanghai Mental Health Center were investigated by one day survey on each June 1st from 2005 to 2008. The most common diseases treated with antidepressants, the most commonly used antidepressants, the average dosage of antidepressants and the combination use of antidepressants were analysed. Results The most common diseases treated with antidepressants were affective disorder, schizophrenia and neurosis. The prescription rate of tricyclic antidepressants declined year by year, and that of selective serotonin reuptake inhibitors (SSRIs) fluctuated moderately, while that of antidepressants of newer generation with the other transmitter mechanisms such as venlafaxine, mitrazapine and trazodone increased gradually. Single antidepressant prescription was common, while the combination use of antidepressants accounted for a small portion. Combination use of antidepressants with one psychotropics (antipsychotics, mood stabilizer, sedative hypnotics) was common, while with two were less frequently occurred. Conclusion Prescriptions of antidepressants for patients with psychosis hospitalized in Shanghai Mental Health Center from 2005 to 2008 are relatively safe and reasonable. Antidepressants of newer generation have been widely used in clinics, and SSRIs have been serving as the major antidepressants.

Objective To investigate a method for the purification of the N?terminal peptide fragment(NT)of the myocardial calcium channel Cav1.2,and characterize its interaction with calmodulin(CaM). Methods EscherichiacoliBL?21 cells were transformed with plasmid pGEX?6p?3/NT harboring the NT?GST fusion gene. The cells harboring pGEX?6p?3/NT were cultured and protein expression was induced with isopropyl?β?D?thiogalactoside(IPTG). Then,the GST?NT fusion protein was purified by using glutathione Sepharose 4B(GS?4B)beads. GST was cleaved off with the PreScission protease,and SDS?PAGE was performed to detect the purity and relative molecular weight of the purified peptide. Further, GST pull?down assay was performed to characterize the interaction of the NT peptide with CaM. Results SDS?PAGE analysis showed that the NT peptide was successfully purified,with high purity. Results of the GST pull?down assay showed that the NT peptide could interact with CaM. Conclusion This study establishes a method for the purification of the NT peptide and lays the foundation for further research on the interaction partners and biological functions of NT.
