Objective To prepare centromere-associated protein E(CENP-E)polyclonal antibody with specificity by using New Zealand white rabbits.Methods Prokaryotic expression plasmid of pHis-CENPEC410 was constructed by molecular cloning technique and then transformed into competent cells of E.coli BL-21 (DE3).HisCENPEC410 fusion protein was induced by isopropyl β-D-thiogalactoside (IPTG) and purified by affinity chromatography using Ni-NTA beads.The purified protein was used as antigen to immune New Zealand white rabbits to produce spccific polyclonal antibody of CENP-E.The antibodies serum was detected by immunoblotting and co-immunoprecipitation,and the purified antibodies were detected by immunofluorescene staining.Results The results of immunoblotting and co-immunoprecipitation demonstrated that the antibody serum was effective and the purified antibody could be applied to immunofluorescene test.Conclusions CENP-E polyclonal antibody with high specificity and sensitivity was obtained,which lay the foundation for the follow-up study of CENP-E.

Objective A systematic review of implementation outcomes of the essential medicine system in China to identify scientific evidences for a better system.Methods A systematic review is made to extract data from the research papers on outcomes of the essential medicine system,followed by an analysis and description of such data.Results Of the 87 papers included,most of them focused on primary care institutions,while four of them on residents or patients,and one of them on pharmaceutical enterprises.The study found the medical institutions with rising availability of essential drugs,lowered medicine costs,rising or dropping business volume,and apparent drop of out-of-pocket expenses for patients.These have encouraged rational drug use.Evidences in hand indicate expected outcomes from the essential medicine system.Conclusion Current researches on the system focus on primary care institutions in developed areas in China,lacking rigorous design.Studies of broader scale,further depth and more rigorous designs of the implementations of the system are recommended for evaluation of the impacts and outcomes of the system on various stakeholders of the policy.

This paper is to report the development of a rapid and sensitive method for the determination of s-oleylpropanolamide (OPA) in various tissues of rat (brain, heart, lung, liver, spleen, small intestine, kidney, adipose tissue and muscle), and to assess the applicability of the assay to tissue distribution. OPA was extracted by liquid-liquid extraction method with undecylenoylethanolamide as an internal standard. The concentrations of OPA were determined by LC-MS/MS after a single intragastric dose of 50 mg x kg(-1) at 4 time points (5 rats per group). With multiple reactions monitoring mode (MRM) the limit of quantification (LLOQ) was determined at 1 microg x L(-1). The calibration curve was linear from 1 to 2 x 104 microg x L(-1) (r > or = 0.999 0) for tissue homogenates. Validation parameters such as accuracy, precision and recovery were found to be within the acceptance criteria of the assay validation guidelines. The highest concentration was found in small intestine (the highest time point is 15 min) and heart (the highest time point is 90 min). The assay is rapid, sensitive and applicable to studying tissue distribution of OPA in rats.

Objective To evaluate the role of transient receptor potential ion channel 1 (TRPA1) in the spinal dorsal horn neurons in maintenance of neuropathic pain in rats.Methods Fifty-six adult male SpragueDawley rats,weighing 200-250 g,were randomly divided into 4 groups (n =14 each):sham operation group (group S); chronic compression of dorsal root ganglia (CCD) group; CCD + dimethyl sulfoxide group (group D); and CCD + TRPA1 blocker HC-030031 group (group H).CCD was produced by infiltrating the L5 intervertebral foramen with 50 μl of a hemostatic matrix (SURGIFLO) in anesthetized rats in CCD,D and H groups.In D and H groups,10％ dimethyl sulfoxide 20 μl and HC-030031 50 μg were injected intrathecally at 7 days after CCD operation,respectively.Paw withdrawal threshold to mechanical stimulation (PWMT) was measured at 1 day before operation (T0),at 1 h before intrathecal administration (T1),and at 1,2,4,6,8,and 24 h after intrathecal administration (T2-7).Six rats in each group were sacrificed at T4 and T7,the L3-5 segments of the spinal cord were obtained for determination of TRPA1 expression in the spinal cord by Western blot.Results Compared with group S,PWMT was significantly decreased at T1-7,the expression of TRPA1 in the spinal cord was up-regulated at T4 and T7 in CCD and D groups,and the PWMT was decreased at T1 and T5-7 and the expression of TRPA1 was up-regulated at T7 in H group (P ＜ 0.05).Compared with CCD group,the PWMT was significantly increased at T2-5 and the expression of TRPA1 was down-regulated at T4 in H group (P ＜ 0.05).Conclusion TRPA1 in the spinal dorsal horn neurons is involved in the maintenance of neuropathic pain in rats.

Sixty patients with esophageal carcinoma undergoing thoracoscopic-laparoscopic resection were randomly divided into two groups with 30 cases in each group:endobronchial blocker was used during operation in group E and double-lumen tube( DLT) was used in group D.The results showed that compare to group D,intubation time was shorter and the incidence of postoperative hoarseness and sore throat was lower in group E [(27.4 ±8.6) vs.(37.2 ±10.3)s, 1 and 9 cases,5 and 14 cases, all P<0.05 ]; while the incidence of blockage shifting was higher in group E than group D (4 cases and 0, P<0.05).There were no significant differences in positioning time and effects of one lung ventilation between two groups[(115.6 ± 25.2) vs.(112.2 ±27.2) s, P>0.05].The study indicates that application of endobronchial blocker can reduce the incidence of postoperative hoarseness and sore throat and shorten the intubation time;especially, it is easy to operate and there is no need to replace the tube after surgery.

OBJECTIVE:To investigate the characteristics of serious ADR in psychiatric hospital,and to provide reference for effective and safe use of drugs in the clinic. METHODS:114 cases of serious ADR in our hospital from 2004 to 2015 were ana-lyzed retrospectively in terms of general information,primary disease,route of administration,dosage form,drug types,organs or systems involved in ADR and clinical manifestations,top 5 ADR-inducing drugs and main clinical manifestations,etc. RESULTS:Of 114 serious ADR cases,the number of female was more than that of male(71/43). Patients aged 21-30 years old took up the greatest proprotion(35 cases,30.70%). The main involved primary disease was schizophrenia(54 cases,47.37%). Oral adminis-tration-induced ADR was most common(103 cases,90.35%). The main involved drugs were antipsychotics,occupying the great-est proportion(75 cases,65.79%). Digestive system involved was the most common(53 cases,42.74%), Olanzapine tablets had the highest incidence of serious ADR (23 cases,18.55%),the main clinical manifestation were both abnormal liver function. There were 8 cases of new serious ADR (7.02%). Most of the ADR can be cured after drug withdrawal or countermeasures,no death case was found. CONCLUSIONS:Psychiatric drugs can induce serious ADR as treat psychiatric disease,among which the in-cidence of ADR induced by Olanzapine tablets is the highest and mainly manifestes digestive system symptoms. It is suggested to strengthen serious ADR monitoring to promote the safe use of drugs.

Objective To study and analyze the clinical effect of zoledronic acid in the treatment of bone metastasis in patients with lung cancer.Methods 50 cases of lung cancer patients with bone metastasis from January 2015 to December 2016 in our hospital were selected and randomLy divided into two groups, the control group and the experimental group, with 25 patients in each group.The control group was treated with pamidronate intravenous drug treatment, patients in the experimental group of zoledronic acid monotherapy in the treatment of.After treatment for a period of time, the relative clinical indicators of the experimental group and the control group were compared and analyzed.Results After the corresponding treatment, 3 patients in the experimental group had complications, the proportion was 12%, and 2 cases in the control group had adverse reactions, the incidence was 8%.The incidence of adverse reactions and the effectiveness of pain treatment in the experimental group were not significantly different from those in the control group, and there was no statistical significance.After treatment, the quality of life scores and general status scores of the experimental group and the control group were significantly higher than those before treatment, with statistical difference(P<0.05).There was no significant difference in the quality of life score and general condition score between the experimental group and the control group, and there was no statistical significance.Conclusion Zoledronic acid monotherapy in the treatment of metastasis corresponds largely to pamidronate treatment for lung cancer patients with bone, can improve the treatment effect and quality of life in a large extent, help the patients to relieve pain, with further clinical promotion and application significance.
