Separations of neurotransmitters such as dopamine (DA), ser otonin (5-HA), norepinephrine (NE) and epinephrine (E) were performed successf ully using a homemade electric field modulated capillary electrophoretic system, which could offer both radial and axial electric fields with only one high volt age power supply. DA and 5-HT were eluted simulaneously and could not be resolv ed in 0.01 mol/L phosphate buffer at pH 2.5. Alcohol additives, such as methanol , ethanol or 1-propanol were added to the buffer to change the solvation shell of the solutes, which changed their effective sizes and electrophoretic mobiliti es of the solutes accordingly. The optimum composition was a buffer of 20% (V ／V） 1-propanol, with resulted resolutions 0.74 (DA/5-HT), 0.56(5-HT/NE) and 0.77 (NE/E). If a positive radial voltage of 6.6 kV was applied, the resolut ions were improved to 1.48, 0.71 and 1.32, respectively.

OBJECTIVE: To evaluate the irrational use of drugs in the department of cardiovascular diseases.METHODS: The irrational use of drugs in the department of cardiovascular diseases from Nov,2007 to Aug 2008 was analyzed statistically.RESULTS: Of the total 194 inpatients(1 745 times in total) investigated,irrational use of antibiotics were found in 118 cases,accounting for 60.82% of the total inpatients or 6.76% in the total 1 745 times;26 cases involved irrational perioperative use of antibiotics,accounting for 1.49% of the total 1 745 times;76 cases had irrational use of non-antibiotics,accounting for 39.18% of the total inpatients or 4.36% of the total 1 745 times.The irrational drug use in the cardiovascular department witnessed an improvement ever since Feb 2008 when the full-time clinical pharmacists began their work in this department.CONCLUSION: The clinical pharmacists can enhance the clinical rational drug use level by summarizing experience and carrying out pharmaceutical care accordingly.

Objective To compare the effects of total intravenous anesthesia(TITA) by using remifentanil combined with propofol and intravenous-inhaled anesthesia by using propofol combined with sevoflurane on emergence agitation(EA) in children undergoing surgery of obstruction sleep apnea syndrome(OSAS). Methods Forty children of 3 to 7 years old scheduled for elective surgery of OSAS were randomly divided into TITA group(group T,n=20) and combined anesthesia group(group C,n=20).Patients in group T were induced with remifentanil 1 ?g/kg,midazolam 0.2 mg/kg,propofol 2.5 mg/kg and rocurolnium 0.6 mg/kg and maintained with remifentanil(0.4-0.5 ?g?kg-1?min-1) and propofol(4-6 mg?kg-1?h-1) until the end of the operation.Patients in group C were induced with midazolam 0.2 mg/kg,propofol 2.5 mg/kg and rocurolnium 0.6 mg/kg and maintained with propofol 4-6 mg?kg-1?h-1 and sevoflurane inhalation(1.2-1.4 MAC) until the end of the operation.EA was evaluated by 5-point scoring scale. Results The score of EA was significantly lower in group T than that in group C(P

To introduce the international registration condition of acupuncture clinical research. With the examples of World Health Organization International Clinical Trials Registry Platform and the U. S. National Institutes of Health Clinical Registration Platform, the registration method and current condition of acupuncture clinical trials in international clinical trials registration platform were analyzed. The results indicate that the number of acupuncture clinical trials registration is gradually increased and the registration number from China is on the rise as well. But most domestic acupuncture clinical researches haven't been registered arid the researchers' valuing degree for clinical trials registration and methodology research needs to be improved.

Objective · To investigate the effects of ox-LDL on the proliferation of rat theca cells and expression of LXR-α and StAR, two genes associated with androgen biosynthesis. Methods · The expression of LXR-α in the ovarian tissue of rats was determined by immunohistochemistry. Primary theca cells were isolated and collected from rat ovary and cultured in vitro. Furthermore, the theca cells were treated with 25, 50, 100, 150, 200, 300 and 400 mg/L ox-LDL, respectively. The variations in LXR-α mRNA were identified using real-time PCR. MTT assay was performed to detect cell viability. The expression of LXR-α and StAR was measured by Western blotting analysis. Results · The effect of ox-LDL on the proliferation of rat theca cells and the levels of LXR-α and StAR in theca cells was in a concentration-dependent manner. Following exposure to various concentration of ox-LDL for 24 h, the proliferation of theca cells was induced by low concentration of ox-LDL (25-150 mg/L), and 100 mg/L ox-LDL showed the most significant inducing effect. Moreover, the cell survival rate was diminished considerably following with ox-LDL concentration increasing, especially lowered by 400 mg/L ox-LDL. The mRNA level of LXR-α was increased with low concentration of ox-LDL (25-150 mg/L) and the impact of ox-LDL on the induced expression of LXR-α mRNA was considerably distinct at the concentration of 150 mg/L. On the other hand, the expression of LXR-α mRNA was reduced with high concentration of ox-LDL, and the impact of 400 mg/L ox-LDLwas substantially distinct. The protein expression levels of LXR-α and StAR were increased with 150 mg/L ox-LDL, but StAR protein level in 150 mg/L ox-LDL group revealed no significant difference when compared with control group. The expression of LXR-α and StAR protein was significantly inhibited with 400 mg/L ox-LDL in the rat theca cells. Conclusion · Low concentrations of ox-LDL can induce the proliferation of theca cells, and promote the expression of StAR and LXR-α. Whereas, high concentrations of ox-LDL can reduce the cell viability and inhibit the expression of StAR and LXR-α.

The paper is aimed to identify SNP in Sarcandra glabra and Chloranthus spicatus, and authenticate S. glabra from Ch. spicatus and the mixture by using PCR amplification of specific alleles. SNPs in the ITS sequences of S. glabra and Ch. spicatus were found by ClustulX 2. 1 program and Bioedit software. Primers for authentic S. glabra and Ch. spicatus was designed according to the SNP site, and ITS sequence universal primers plus to the authentic primer to construct a multi-PCR reaction system, and then optimized the PCR reaction system. Five hundred and eighty band special for S. glabra and 470 bp band special for Ch. spicatus were found by using multi-PCR reaction. The multi-PCR reaction system could be applied to identify S. glabra and Ch. spicatus's leaves.

Objective To investigate the expression of phosphorylated protein kinase B1 (pAkt1) and human telomerase reverse transcriptase (hTERT) in ovarian epithelial carcinoma (EOC) and its relationship with prognosis, and to analyze the correlation between pAkt1 and hTERT expression. Methods 92 patients with EOC in Tangshan Gongren Hospital from January 2012 to December 2016 were selected. The expressions of hTERT and pAkt1 proteins were detected by immunohistochemistry. The relationship between the expressions of pAkt1 and hTERT proteins and their relationship with clinical prognosis were analyzed. Results Of the 92 patients with EOC, 68 cases (73.9 %) had positive expression of pAkt and 52 cases (56.5 %) had positive expression of hTERT. There was no significant correlation between expressions of pAkt1 and hTERT proteins in EOC (r= 0.284, P= 0.633). The expressions of pAkt1 and hTERT proteins were not related with age, tumor pathology type and the International Federation of Gynecology and Obstetrics (FIGO) staging (all P> 0.05), but had significant association with tumor pathology differentiation (χ2= 2.694, P= 0.005; χ2=2.284, P=0.018). The disease-free survival of patients with both pAkt1 and hTERT positive was shorter than that of the other groups (P= 0.013). Conclusion The prognosis of EOC patients with high expression of pAkt1 and hTERT proteins is poor.
