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.

As two main research methods, qualitative study and quantitative study are different in theoretical basis, research methods, research goal, the relation between researchers and those who are studied as well as applied fields. They should be combined in education research, however, for education is a complicated humanism phenomenon.

AIM: To study the correlation between the drug effects and serum HPLC fingerprint from active compositions of Radix paeoniae alba and Radix et Rhizowa Glycyrrhizae. METHODS: Orthogonal design of L_9(3~4) of the different combinations of three active compositions of paeoniflorin,glycyrrhiza flavoues and Glycyrrhizic acid were prepared,antalgic pharmacological experiments of mice were carried out.The fingerprints of the serum were tested by HPLC method and different chromatographic peaks were obtained.Correlation analysis was applied to interelationship between the area of each peaks and the pharmacologic data. RESULTS: Correlation coefficients were different between pear areas and analgetic coffec. CONCLUSION: This study provides a significant try of investigating the compatibility of composite herbal medicines.

OBJECTIVE: To seek approach for the protection of domestic pharmaceutical enterprises with immature creativity and to ensure drug accessibility. METHODS: An analysis was performed applying the theory of demand elasticity by comparing the attributes of health right and patent right etc based on TRIPS protocol and the related practice abroad. RESULTS & CONCLUSIONS: For a developing country, China should give top priority to the short-term urgent needs, such as to meet people's medication demands, followed by meeting the long-term demands, such as to encourage independent intellectual property rights. Hence, drug accessibility-related system in drug patent system should be evolved step by step.

It is essentially indispensable to use multimedia methods in teaching "Clinical Medicine Outline". Such usage can diversify the teaching approaches and play a very important role in improving teaching methods and deepening students’ comprehension of course knowledge. Some problems existing in application of multimedia in the teaching process need to be settled.

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

Objective? To?understand?the?distribution?and?antibiotic?resistance?profile?of?clinical?isolates?in?the?Affiliated?Hospital?of Youjiang Medical University during 2015. Methods The pathogenic microorganisms were isolated from inpatients from January to?December,?2015?in?the?Affiliated?Hospital?of?Youjiang?Medical?University.?Antimicrobial?susceptibility?testing?was?carried?out?according?to?a?unified?protocol?using?Kirby-Bauer?method?or?VITEK?2-Compact?systems.?The?results?were?interpreted?according?to CLSL breakpoints released in 2014, and analyzed by WHONET 5.6 software. Results A total of 4004 strains of bacteria were collected, including 1146 (28.6%) strains of gram-positive bacteria, and 2858 (71.4%) strains of gram-negative organisms. The?prevalence?of?MRSA?and?MRCNS?was?25.8?%?and?79.4?%,?respectively.?MRSA?and?MRCNS?strains?were?significantly?more?resistant to most antibiotics than MSSA and MSCNS except trimethoprim-sulfamethoxazole. Most of the S. pneumoniae isolates were from non-meningitis patients, showing high resistance rate to macrolides and tetracycline, but very low resistance rate to quinolones. Enterococcus isolates were mainly E. faecium and E. faecalis. More E. faecium were resistant to high-level gentamicin and high-level streptomycin than E. faecalis. E. faecium isolates were generally more resistant than E. faecalis to most of the antimicrobial agents tested except clindamycin and tetracyclines. But no gram-positive cocci were found resistant to vancomycin, linezolid or tigecycline. ESBLs-producing strains accounted for 53.1% of the E. coli strains and 28.5% of K. pneumoniae isolates. Enterobacteriaceae isolates were still very susceptible to carbapenems. E. coli isolates were more resistant to most of the antimicrobial agents tested than other Enterobacteriaceae except to piperacillin-tazobactam and carbapenems. Enterobacteriaceae showed higher resistance to trimethoprim-sulfamethoxazole than the other antibiotics tested. Majority of P. aeruginosa isolates were susceptible to all the antibiotics tested (<10% resistant). A. baumannii?strains?showed?significantly?higher?resistance rate than P. aeruginosa to all the antibiotics tested. Conclusions Most of the data in this report are consistent with the national?data?in?terms?of?antimicrobial?resistance?profile.?These?data?are?useful?for?rational?use?of?antibiotics.
