This article introduced the practice of emergency personnel cultivation according to order form based on the cooperation between Cang Zhou Medical College and the Beijing Red Cross emergency rescue center. The implementation process: First, we tried and built cooperative relation with the enterprises and public institutions which had strong cooperative intention, high demand and advanced techniques by field investigation. Second, we signed order training agreement, made clear the rights and obligations of both sides. Then, we selected the best students and formed the ordered class. Both sides organized the professional construction committee together. After much argument we thrashed practical talent training projects and professional development plans and implemented them strictly. We also built up a high quality team which involved full-time teachers as well as part-time teachers with balanced age and education. Besides, we adopted two plus one training pattern and em-ployed the best (the rate of employment beyond 80%). Thus, the win-win situation of students, schools and hospitals was realized.

Jinyingzi is the dry ripe fruit of Rosa leav gata Michx.. It contains mainly tannic acid, malic acid, citric acid, vitamin C and saponins. Its effect on urinary sy stem was studied on mouse Pollakiuria model by severing hypogastric nerve. Results showed that the water extract of R. laevigata can decrease the frequency and prolong the interval of urination and increase the quantity of eacn urination. The said extract can inhibit the automatic contraction of isolated rabbit jejunal smooth muscle and antagonize the spasmodic contraction arouscd by acetylcholine and barium chloride of isolated rabbit jejunal smoothmusele, and isolated vesical smooth muscle of mouse, and antagonize reaction of contractility aroused by noradrenalin on isolated thoracic aorta strips of rabbit. All of the the three inhibitions of smooth muscle contraction showed signicant dose-response curve.

Objective To investigate the changes of serum angiopoietin-like protein 3 (Angptl3) and adiponectin levels in patients with metabolic syndrome (MS) in order to understand their association with the MS. Methods Serum Angptl3 and adiponectin levels were measured by sandwich ELISA in a group of 111 patients with MS and 152 normal controls. Results Serum adiponectin was lower in the MS patients than in the control subjects [4.22(1.01-23.29) μg/mL vs. 5.41(0.97-22.27) μg/mL, P＜0.05]. With regard to serum Angptl3, there was no significant difference between the 2 groups(P＞0.05). Serum adiponectin was correlated to Angptl3 and high density lipoprotein-cholesterol (HDL-C)(P＜0.001) and negatively correlated to body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), triglyceride (TG), fasting plasma glucose (FBG), fasting insulin (FINS) and homeostatic model assessment method-insulin resistance (HOMA-IR) (P＜0.001). Serum Angptl3 was positively correlated with adiponectin (P＜0.001). Serum adiponectin was found to be independently positive determinant for Angptl3 concentrations (b′=0.256, P＜0.001). Adiponectin was inversely correlated with TG and HOMA-IR (b′=-0.234, -0.145, P＜0.001). Conclusion Adiponectin is decreased in MS patients and may be correlated to Angptl3.

Objective To study the effects caused by novel antipsychotics quetiapine and aripiprazole on concentrations of platelet 5-HT in patients with schizophrenia,and to explore the relationships among the change of platelet 5-HT concentrations, psychiatric symptoms and the sensitivity of therapy. Methods Sixty-eight patients with schizophrenia meeting International Classification of Diseases-10 (ICD-10) were enrolled in the study. They were divided into quetiapine group(n=34) and aripiprazole group(n=34) according to the sequence of admis-sion. The platelet 5-HT concentrations were measured with high performance liquid chromatography method(HPLC-ECD). The positive and negative syndrome scale (PANSS) was used to evaluate the psychopathology. Treatment emergent symptom scale (TESS) was used to evaluate the side effects. PANSS,TESS were used at pre-treatment,the end of 4th and 8th week of treatment. Results The platelet 5-HT concentrations in two groups were higher af-ter 8 weeks treatment,but had no statistically significant difference (P>0.05). In quetiapine group, the platelet 5-HT concentration was (458.89±233.36) ng/10~9 at the pre-treatment, and (554.31±313.22) ng/10~9 at the end of treatment (t=1.709, P=0.099). In aripiprazole group, the platelet 5-HT concentration was (409.83±149.32)ng/10~9 at the pretreatment, and (421.27±245.96)ng/10~9 at the end of treatment (t=0.321, P=0.819). There was no difference between two groups(P>0.05). Stepwise regression analysis showed the changing rate of platelet 5-HT concentrations was positively correlated with the dosage of quetiapine (r=0.385, P=0.039).It was positively correlated with the decreasing rate of PANSS in aripiprazole group(r=0.391, P=0.040). Con-dusion The changes of psychiatric symptoms and the dosages of antipsychotics maybe have intimate relationships with platelet 5-HT concentrations in the course of medication.

Objective To assess subclinical left ventricular systolic and diastolic function in normotensive latent autoimmune diabetes in adult (LADA) patients with normal ejection fraction and fractional shortening by velocity vector imaging (VVI) . Methods Digital dynamic imaging of 60 normotensive LADA patients and another 60 healthy subjects were collected. The longitudinal velocity, strain, and strain rate were measured in systolic, early and later diastolic period respectively and the peak time of velocity, strain, and strain rate were recorded. The parameters were analyzed. Results Compared with the control group, all of the measured parameters of LADA patients were significantly lower (P ＜ 0. 01), except the later diastolic strain (P ＞ 0. 05) . The peak time of myo-cardial longitudinal velocity, strain and strain rate was lengthened compared with the control group, but without statistical significance (P ＞ 0. 05). Conclusion VVI is a novel and noninvasive tool to quantitatively and objectively assess left ventricular regional systolic and diastolic function in the LADA patients. It can make trustworthy early diagnose of abnormal left ventricle myocardial performance in patients with subclinical LADA.

Aim To investigate the reversal effect of vatalanib, a novel kinase inhibitor, on multidrug re-sistance in cancer cells and its mechanism. Methods The cytotoxicity and reversal effects of vatalanib were evaluated in both resistant and sensitive tumor cell lines by MTS or SRB assays. The intracellular accumu-lation of fluorescence substrates ( Rh-123 , MX and ADR for P-gp, BCRP, MRP1, respectively) were ana-lysed by flow cytometry. Western blot or qRT-PCR was
used to determine the protein or mRNA expression lev-el of BCRP. The effect of vatalanib on ATPase activity of BCRP was determined using crude membranes pre-pared from HEK293/ABCG2 cells. Results Vata-lanib at the nontoxic dose ( 5 μmol · L-1 ) potentially reversed BCRP-mediated MDR in cancer cells, howev-er it had no effect on P-gp or MRP1 mediated MDR. Vatalanib did not alter the intracellular accumulation of MX in HEK 2 9 3 / ABCG 2 , and had no influence on the
BCRP-mediated drug efflux. The ATPase assay indica-ted that vatalanib may serve as a substrate of BCRP. Furthermore, vatalanib dramatically suppressed levels of both the protein and mRNA expression of BCRP in concentration-and time-dependent manners. However, reversal concentration of vatalanib had no influence on the total and phosphorylated forms of AKT and ERK1/
2 in resistant cancer cells. Conclusion Vatalanib could significantly reverse BCRP-mediated MDR with specificity, and its mechanism may correlate with the down-regulation levels of BCRP both mRNA and pro-tein in resistant cancer cells.

The purpose of this study was to evaluate the effect of adenosine A2A receptor antagonist ZM241385 on amygdala-kindled seizures and its roles in epileptogenesis. Electrodes were implanted into the right amygdala of male adult Wistar rats. Kindling was accomplished by using stimulus strength of 500 μA applied daily to the amygdala until 10 consecutive stage 5 seizues were induced. Then effect of ZM241385 was studied in fully kindled rats after intracerebroventricular administration of the drug. In addition, the effect on kindling progression was evaluated through ZM241385 injection before daily stimulation. In all experiments, behavioral changes in the rats in response to ZM241385 were monitored closely. The results showed that, in fully amygdala-kindled rats, ZM241385 (0.001-0.1 nmol/L) decreased afterdischage duration (ADD), motor seizure duration (MSD), stage 5 duration (S5D) and seizure duration (SD), but only the effect on ADD was dose-dependent. The doses of 0.001-0.1 nmol/L had no influence on stage 4 latency (S4L) and seizure stage (SS). The dosages of 0.0001 and 1 nmol/L of ZM241385 did not exert any effect on all seizure parameters. In contrast to the results in fully amygdala-kindled rats, ZM241385 (0.001-0.1 nmol/L) had minimal or no effects on the progression of amygdala-kindled seizures. We are led to the conclusion that although ZM241385 had no influence on the progression of amygdala-kindled seizures, it had potent anti-convulsant profile and little adverse effects at the dosage of 0.001-0.1 nmol/L, suggesting that the agent is effective against the amygdala-kindled seizures.
