ConclusionIn order to help graduate students find jobs successfully, first of all, students’ ability with more professional skills should be improved;moreover, their sense in searching job should renewed through training courses, job services and personal instructions;in the end, more job information should be provided by establishing service network.

Objective: To investigate the central oxidative stress characteristics of rats with postoperative fatigue syndrome (POFS) and the antifatigue mechanism of ginsenosides Rb1. Methods: Rat models of POFS were established by using the 70% middle part of small bowel resection method. Ninety-six SD rats were randomly divided into control, model, and ginsenoside Rb1 (GRb1, 10 mg/kg) groups by weight. Rats in each group were administered 1 h before operation and were then divided into four subgroups at days 1, 3, 7, and 10. Morris water-maze test was done on postoperative days 2-7. Meanwhile, grasping test, malondialdehyde (MDA) content, superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities were detected on postperative days 1, 3, 7, and 10 and the ultrastructure of hippocampal CA1 area was observed through electron microscope. Results: Compared with the control group, the maximum grip of model rats had an obvious decline on days 3, 7, and 10 (P < 0.05). The total average escape latency was significantly extended (P < 0.05) and the platform crossing times were significantly reduced (P < 0.05). Compared with the model group, the above indexes of rats in GRb1 group were effectively improved after the intervention (P < 0.05). Compared with the control group, on postoperative days 1 and 3, the MDA content was obviously increased (P < 0.05) and SOD activity was obviously raised (P < 0.05). On postoperative day 7, GSH-Px activity was obviously raised (P < 0.05). After the intervention of GRb1, the MDA content was effectively decreased (P < 0.05), SOD and GSH-Px activities were effectively improved (P < 0.05). Electron microscope showed that the ultrastructure of hippocampal CA1 area of rats in GRb1 group was significantly improved. Conclusion: Surgical stress leads to the state change of central oxidative stress; GRb1 could reduce the damage of oxidative stress by strengthening the activity of central anti-oxidant enzymes, so as to protecte central neurons, which may be one of the mechanisms against POFS.

Aim: To study pharmacokinetics of aconitine,mesaconitine and hypaconitine in rats after single oral administration of decoctions composed with Radix Aconiti Lateralis.Methods: Four groups of rats were orally administered four decoctions including decoction a(Sini decoction),decoction b(decoction composed with Radix Aconiti Lateralis),decoction c(decoction composed with Radix Aconiti Laterali and Radix et Rhizoma Glycyrrhizae Praeparata Cum Melle)and decoction d(decoction composed with Radix Aconiti Laterali and Rhizoma Zingiberis),respectively.Quantitative analysis of aconitine,mesaconitine and hypaconitine in rat plasma was achieved using a liquid chromatography-electrospray ionization/tandem mass spectrometry method.Pharmacokinetic parameters were estimated using DAS 2.0.Results: Pharmacokinetic parameters of aconitine,mesaconitine and hypaconitine were different after oral administration of four decoctions according to Radix Aconiti Laterali combined with different herbal medicines.Multiple peaks were observed in plasma concentration-time curve after oral administration of the decoction of herb couple Radix Aconiti Laterali and Radix et Rhizoma Glycyrrhizae Praeparata Cum Melle,and the results showed a delay in tmax and a prolonger in MRT0-t compared with the decoction of Radix Aconiti Latera-lis.When Radix Aconiti Lateralis was combined with Radix et Rhizoma Glycyrrhizae Praeparata Cum Melle and Rhizoma Zingiberis at the same time in Sini decoction,tmax was delayed too but MRT0-t,was shorten than that of the group of Radix Aconiti Lateralis.Conclusion: The pharmacokinetic parameters of the three compounds obtained in this work shows that the pharmacokinetics of aconitine,mesaconitine and hypaconitine were influenced diversely when Radix Aconiti Laterali was combined with different herbal medicines.

This study examined the mechanism by which the gastric cancer cells lead to early peritoneal metastasis. HMrSV5 cells, a human peritoneal mesothelial cell line, were co-incubated with the supernatants of gastric cancer cells. Morphological changes of HMrSV5 cells were observed. The cell damage was quantitatively determined by MTT assay. The apoptosis of HMrSV5 cells was observed under transmission electron microscope. Acridine orange/ethidium bromide-stained condensed nuclei was detected by fluorescent microscopy and flow cytometry. The expressions of Bcl-2 and Bax was immunochemically evaluated. The results showed that conspicuous morphological changes of apoptosis were observed in HMrSV5 cells 24 h after treatment with the supernatants of gastric cancer cells. The supernatants could induce apoptosis of HMrSV5 cells in a time-dependent manner. The supernatants could up-regulate the expression of Bax and suppress that of Bcl-2 in HMrSV5 cells. These findings demonstrated that gastric cancer cells can induce the apoptosis of HPMCs through supernatants in the early peritoneal metastasis. The abnormal expressions of Bcl-2 and Bax may contribute to the apoptosis. Anti-apoptosis drugs promise to be adjuvant chemotherapeutic agents in the treatment of peritoneal metastasis of gastric cancer.

Objectives To analyze the deployment of medical equipment and its impacts on medical services of hospitals.Methods Existing data collection,a survey of public hospitals and a chart review of acute myocardial infarction(AMI)inpatients were used to collect related data.Gini coefficients,Chi-square and multivariate model were used to analyze deployment of medical equipment and its impacts on medical services.Results The number of CTs and that of CTs per million population in Pudong new area were higher than those of MRIs and DSAs,and the distribution of CTs among districts in Shanghai was relatively equal(Gini coefficient was 0.20).But lack of DSAs in some public general hospitals had affected the AMI inpatient care.Conclusions Public hospitals and governments in China should keep at a balance the demand of medical services,deployment level of medical equipment,and financial affordability for the society,governments and hospitals.

Objective To understand the clinical value on the detection of carcinoembryonic antigen mRNA (CEA mRNA), cytokeratin 19 mRNA (CK19 mRNA) and telomerase in blood for the monitoring of blood metastasis of lung cancer. Methods CEA mRNA and CK19 mRNA were detected by reverse transcriptase-nested primers-polymerase chain reaction, telomerase was detected by telomeric repeat amplification protocol-hybridism-enzyme-linked immunosorbent assay in peripheral blood. Results The positive rates of the three tumor markers in lung cancer group were much higher than the non-tumor group and the health group (P<0.001). The sensibility of CEA mRNA and telomerase were much higher than CK19 mRNA (P<0.01). The positive rates of the markers in TNM stages Ⅲ and Ⅳ were much higher than in stages Ⅰ (P<0.05 to P<0.01). Conclusion It had high value that detecting CEA mRNA, CK19 mRNA and telomerase in peripheral blood on the discovery of blood metastasis of lung cancer. Among them, the clinical value of CEA mRNA and telomerase are higher than CK19 mRNA, and combined assay of the markers can improve the sensibility.

This study is to investigate the effects of concentration, intestinal section, pH, paracellular route, substrate/inhibitor of enzyme (CYP3A) and proteins (P-gp, MRP2, SGL1) on the absorption of forsythoside A. The absorption of three concentrations (2.6, 5.2, and 10.4 microg x mL(-1)) of forsythoside A in different intestinal segments was studied with phenol red as the marker by rat circulation in situ. The results showed that the residue of forsythoside A with different concentrations had little significant difference from that obtained after perfusing via duodenum, jejunum, ileum and colon, which indicated that the absorption of forsythoside A was passive diffusion and had no difference in different segments of rat intestine. The residue of forsythoside A increased to 466.160 and 463.429 microg respectively when cyclosporine (4 microg x mL(-1)) or midazolam (50 micromol x L(-1)) was added to the circulation fluid, which showed significant difference compared to the control group (P < 0.05). Moreover, the residue of forsythoside A showed a tendency of increase with the increase of cyclosporine or midazolam. When digoxin (50 micromol x L(-1)) or EDTA (10 microg x mL(-1)) was added to the circulation fluid, the residue of forsythoside A decreased to 325.110 and 369.888 microg respectively, which showed significant difference as compared to the control group (P < 0.05). Besides, the residue of forsythoside A showed a tendency of reduction with the increase of digoxin or EDTA. However, there is no significant change in the absorption of forsythoside A when the different concentrations of mannitol were added to the circulation fluid. The results above indicated that the absorption of forsythoside A was mainly passive diffusion and involved paracellular route at the same time. In addition, the substrates of P-gp or CYP3A had dose-dependent effect on the absorption of forsythoside A.

OBJECTIVE:To provide reference for better improving the risk perception of Omeprazole sodium for injection in nurses in a third-grade class-A hospital,strengthening risk management of ward drugs and ensuring safety of patients. METHODS:Nurses in the clinical departments in a third-grade class-A hospital where usage frequency of Omeprazole sodium for injection was relatively more were adopted as study subjects and a self-designed questionnaire was used to investigate on related knowledge on medication risk in nurses in emergency department,gastroenterology department,ICU and CCU in 2012 and 2014. RESULTS:51 and 81 questionnaires were distributed in 2012 and 2014,and 51 and 81 were effectively received with effective recovery of 100%and 100%,respectively. In both surveys,100% surveyed nurses could correctly choose one solvent at least,1.96% and 3.70%nurses could correctly choose 2 solvents;correct answering rates of intravenous administration time were 94.12% and 96.30%,re-spectively;correct answering rates of stable duration after preparation were both lower than 9%;correct answering rates of adverse reaction of this drug were 3.92% and 1.23%,respectively;correct answering rates of interaction of this drug were 1.96% and 6.17%,respectively;correct answering rates of stable formulation of this drug were 17.65%and 22.22%,respectively;the propor-tion of nurses observing ADRs were 25.49% and 13.58%,respectively;the proportion of nurses finding inappropriate compatibility were 15.69% and 22.22%,respectively,Ornidazole and sodium chloride injection was the most used incompatible drug;45% or more nurses hoping to strengthen the continuing education of nursing personnel. CONCLUSIONS:Nurses in this third-grade class-A hospital lack certain knowledge on the medication risk of Omeprazole sodium for injection,the drug risk management is not sufficient,and awareness prevention of drug risk is relative weak. It is suggested that the hospital should strengthen drug risk management system,nurses should strengthen the learning about drug risk and play the role of clinical pharmacists in the drug risk management to reduce the related drug risk and incidence of adverse reactions.
