OBJECTIVE:To construct the homologous recombination plasmid of sigB gene from staphylococcus aureus so as to provide the basis for further study of the formation mechanism of its biofilm.METHODS:The target fragment“upstream sequence of sigB,kana-resistance gene,and downstream sequence of sigB”were amplified by PCR from staphylococcus aureus DNA and pEGFP-N2plasmid,respectively,in which the terminals of3interlinked fragments were complementary,and re-stricted enzyme EcoRⅠand XhoⅠsite existed in the sequence terminal,respectively.The fragments were ligated with fusion PCR in turn.Then target fragment was recombinated into plasmid pBluescriptⅡSK(+)according to the instruction manual of commercial kits.After both recombination of pBluescriptⅡSK(+)and vector plasmid pGEM-7zf(+),restricted enzyme SacⅠand XhoⅠ,the homologous recombination plasmid pGEM-7zf(+)-sigB was finally made via T 4 ligation enzyme.RE-SULTS:The target fragments were amplified by PCR and were confirmed with the agarose gel electrophoresis and sequencing.CONCLUSION:The homologous recombination plasmid of sigB gene from staphylococcus aureus is constructed successfully.

OBJECTIVE:To provide a basis for management of use of cephalosporins in hospital METHODS:The cephalosporins used in 18 hospitals of Chongqing in 2001～2003 were statistically analysed in respect to the kind,consumption sum and DDDs etc RESULTS:During the 3-year period,the sum of cephalosporins consumption increased with an annual rate of 23 34%,of which the third generation cephalosporins were the maximum consumption in kind accounting for 50% of total cephalosporins used Compared to those in 2001,DDDs of the third generation cephalosporins increased 540 49%,but DDDc decreased 75 22% As for fourth generation cephalosporins,the annual sum and consumption were under 2% and 0 3% respectively CONCLUSION:The consumption of the third generation cephalosporins has increased sharply In order to reduce and delay the bacteria resistance,it is very important to make measures as soon as possible to control the cephalosporins abuse strictly

OBJECTIVE:To survey and evaluate the present situation and trends o f fluoroquinolones(FQNs) used in hospitals in four provinces,southwest district of China,during the period 2000～2002 METHODS:FQNs used in 51 hospitals in 4 provinces(cities) were analyzed statistically in respect to the sum of money ,main kinds and DDDs etc RESULTS:During the period 2000～2002,a total of 13 kinds of FQNs was used in these hospitals The consumption sums of FQNs in 2000 ,2001 and 2002 were 7 391,9 342 and 13 242 ten-thousand yuans respectively wi th an annual increase rate of 34 08%,of which the main cause was due to the i ncreasing consumption of levofloxacin,sparfloxacin and ofloxacin,however,the DDDs of FQNs in 2001 and 2002 decreased by 17 58% and 19 38% respectively,c ompared with that in 2000,which resulted from the reducing consumption of norfl exacin,but no significant differences were found in the average DDD costs among three years Meanwhile,the nasal drops and eye drops of ofloxacin,ciprofloxac in,norfloxacin and lomefloxacin were consumed a large amount during these three years CONCLUSION:FQN is a kind of commonly-used antimicrobial in southwest d istrict of China And the consumption of some newly-developed FQNs such as levo floxacin and sparfloxacin has increased fast year by year

OBJECTIVE:To provide reference for the reform of the postgraduate training mode of pharmaceutical professional degree. METHODS:Domestic literatures about postgraduate training mode of pharmaceutical professional degree from 2010 to 2013 were searched and combined with the current education situation in China to conclude and summarize the existing problems and reform strategy. RESULTS:Postgraduate education mode of pharmaceutical professional degree in China was still in the explor-atory stage,with shortage of teachers,unreasonable courses,unsound educational structure,nonsupport of the students,imperfec-tion evaluation systems,and so on. Further promoting the reform of postgraduate education mode needs to strengthen teacher teams ’construction,implement cooperative training;improve training program and teaching courses;strengthen dissertation applica-tion-oriented and practice base construction;fully mobilize the enthusiasm and motivation of students;promote the connection of pharmaceutical professional training and vocational qualifications;and improve the quality assurance systems. CONCLUSIONS:Further implementation of postgraduate training mode of pharmaceutical professional degree and postgraduate education of pharma-ceutical professional degree can train the applied talents that meet social needs,improve employment rate of postgraduates and re-duce waste of educational resources.

Objective To investigate the relationship between fractional exhaled nitric oxide (FENO) and asthma predictive index (API) in infants under 3 years of age. Methods Totally 62 cases (under 3 years of age) who were hospitalized from June 2015 to June 2016 and had more than 3 times wheezing over the past year were enrolled in this study. They were divided into two groups according to API:API positive group with 37 cases and API negative group with 25 cases. FENO levels and peripheral blood eosinophil levels were detected and skin prick allergy test (inhalation and ingestion of allergens)was done in all selected children, did skin prick allergy test (inhalation and ingestion of allergens), simultaneous detected peripheral blood eosinophil levels. The parents of the children were investigated by questionnaire to know the children′ history about atopic dermatitis (such as urticaria, eczema, etc) and parents′ wheezing history. Above information was recorded and statistics analysis was made. Results There were no significant differences between two groups in atopic dermatitis inhalation and ingestion of allergens (P<0.01 or <0.05). The level of FENO in API positive group and API negative group was (16.70 ± 11.07), (13.52 ± 11.01) ppb(1 ppb=1 × 10- 9 mol/L), and there was significant difference (P<0.01). Conclusions There are associations between FENO and API, and they have good reference value in predicting the risk of asthma.

Objective To evaluate the endotoxin-neutralizing activity of modeling peptides from the limulus antilipopolysaccharide factor (MPLALFs, Ms) in vitro. Methods The endotoxin-binding activity of Ms was examined by biosensor technique and shown in values of Kon and Kd. The endotoxin-neutralizing effect was analyzed by limulus amebocyte lysate test. Results The biosensor technique results showed that the Kon values of M_0, M_1, M_2, M_3, M_4, M_6, M_8 and M_ 10 binding to LPS 055∶B5 were (840?5.716), (549?6.532), (842?6.530), (627?2.450), (996?5.716), (814?8.982), (556?1.633) and (635?2.449) arc second, of which M_4 and M_1 had the highest and lowest endotoxin-binding activity, respectively. The M_4 reacted to LPS with a Kd of 72.377 ?mol/L. The results obtained by the limulus amebocyte lysate test were the same with those from the biosensor technique. Conclusion M_4 has a potential good endotoxin-neutralizing effect in vitro.

Objective To study the current status of antibiotic usage in Southwest hospital, so as to improve the rationality in applying antibiotic. Methods A total of 1 668 patients in Southwest hospital during Jan 1 to Dec 30, 2003 were investigated in antibiotic usage and the data were sorted and analyzed. Results Antibiotics were administered in 1 247 cases (74.76%), including only 76 cases (6.09%) based on susceptibility test, 39 cases (3.12%) occurred hospital infection. 297 cases (23.81%) abused antibiotics, among which 131 cases (38.04%) were without definite symptoms or with weak signs, 93 cases (31.31%) used more than two kinds of antibiotics, 24 cases (8.08%) frequently changed antibiotic in the treatment, 27 cases (9.09%) inappropriately prolonged administration and 22 cases (7.40%) improperly combined the same antibiotics. Conclusion Irrational utilization of antibiotics exits in clinical work. Therefore, the rational use of antibiotic based on susceptibility tests should be emphasized.
