The aim of this study is to clone the mouse T-bet promoter and enhancer, construct and identify the firefly luciferase reporter gene plasmid pGL4.10-TBX21pr-CNS for T-bet transcription regulation study and its function in signaling of multiple sclerosis. The promoter and CNS of T-bet were predicted by bioinformatics assay. The predicted fragment of mouse T-bet promoter plus CNS was amplified by PCR and cloned into pGL4.10. The recombinant plasmid pGL4.10-TBX21pr-CNS was transferred into Escherichia coli DH5α. The positive clone was identified by double digestion with Kpn I and Sfi I and DNA sequencing. Finally, pGL4.10-TBX21pr-CNS was cotransfected with pRL-TK into 293T cells and Jurkat cells, pRL-TK and pGL4.10 as a control. The luciferase activity in 293T cells (P = 0.012 2) and Jurkat cells (P = 0.002 2) was higher than that of the control group. A fragment of 1 028 bp mouse T-bet promoter plus 1 308 bp CNS was successfully cloned and the firefly luciferase reporter gene plasmid pGL4.10-TBX21pr-CNS was constructed. In 293T cells and Jurkat cells, pGL4.10-TBX21pr-CNS has the promoter functions. This work offers a basic material for the research of T-bet transcription.

OBJECTIVE:To establish a HPLC method for the determination of chlorogenic acid and baicalin in xiaoer qingrening granula.METHODS:The determination was performed on Symmetry Shield RP C 18 ,the mobile phase of chlorogenic acid consisted of acetonitrile-0.4%phosphoric acid soluton(13∶87)and that of baicalin consisted of methanol-water-glacial acetic acid(50∶50∶1),the detection wavelengths of chlorogenic acid and baicalin were327nm and274nm,respectively,the flow rate was1.0ml/min,sample size was20?l and column temperature was25℃.RESULTS:The respective linear sample size range for chlorogenic acid and baicalin was0.1040?g～1.040?g(r=0.9998)and0.6240?g～6.240?g(r=0.9997),with average recoveries respectively at96.4%(RSD=1.4%)and98.0%(RSD=1.1%).CONCLUSIONS:The method is simple,accurate,reproducible and specific,and it can be used for the quality control of xiaoer qingrening granula.

OBJECTIVE: To investigate the perioperative treatments of endoscopic sinus surgery for nasal diseases in patients with coronary heart disease after PCI. METHOD: Clinical data of 12 cases of endoscopie-assised surgery such as nasal tumors resection,functional sinus surgery,correction of deviated nasal septum,low-temperature plasma hemostasis in patients with coronary heart disease after PCI were analyzed retrospectively. RESULT: Serious bleeding did not take place with the 12 cases during surgery, and surgery progressed smoothly; one of patients had heavy nosebleed after surgery, however her condition was stable when received active treatment. Follow-up 3 months to 2 years, nasal diseases of 12 patients recovered well and symptoms were relieved; cardiovascular events such as hemorrhage, thrombosis and so on did not occur. CONCLUSION Due to physiological function of the heart dysfunction in patients with coronary heart disease after PCI,they often accompany a number of trouble issues such as medical disorders, oral antiplatelet drugs, surgery affordability loss and increase surgical risk. Correct and effective perioperative treatments, strictly surgical indications are really necessary which can keep patients safe through perioperative period.

OBJECTIVETo compare the cleaning effect of automatic cleaning machine and manual cleaning on coupling type surgical instruments.

METHODSA total of 32 cleaned medical instruments were randomly sampled from medical institutions in Putuo District medical institutions disinfection supply center. Hygiena System SUREII ATP was used to monitor the ATP value, and the cleaning effect was evaluated.

RESULTSThe surface ATP values of the medical instrument of manual cleaning were higher than that of the automatic cleaning machine.

CONCLUSIONCoupling type surgical instruments has better cleaning effect of automatic cleaning machine before disinfection, the application is recommended.

Objective: To evaluate the bioavallability and bioequivalence of rabeprazole sodium enteric-coated pellets capsules. Methods:A randomized crossover design was performed in 32 healthy male volunteers. A single oral dose of 20 mg rabeprazole sodium enteric-coated pellets capsules ( test preparation) or enteric-coated shell capsules ( the reference capsules) was administrated under fed conditions. The wash period was 7 days. The blood samples were collected at different time points. The concentration of rabeprazole in plasma was determined by an LC-MS/MS method. The pharmacokinetic parameters were calculated by DAS 3. 0 software and the bio-equivalence was evaluated. Results:The maln pharmacokinetic parameters of the two formulations were shown as follows:T1/2 of (2. 20 ± 0. 83)h and(1. 951 ± 0. 515)h,Tmax of (3. 88 ± 1. 11)h and(4. 64 ± 1. 504)h,Cmax of (401. 06 ± 170. 75)ng·ml-1 and(394. 63 ± 215.64)ng·ml-1,AUC0→t of (918.42 ±427.39)ng·h·ml-1 and (994.49 ±520.73)ng·h·ml-1, and AUC0→∞ of(937.30 ± 445.13)ng·h·ml-1 and(1 011.69 ±534.77)ng·h·ml-1. The analysis showed that the maln pharmacokinetic parameters of the two formulations had no significant differences(P>0. 05) except for Tmax(P<0. 05). The relative bioavallability of rabeprazole sodium enteric-coated pellets capsules was (99. 80 ± 7. 20) %. Conclusion:Compared with the reference capsules, rabeprazole sodium enter-ic-coated pellets capsules show the property of higher dispersion degree, milder influence from food, more rapid release and absorption. The enteric-coated pellets capsules and the reference capsules are bioequivalence.

OBJECTIVE:To consolidate the results of special antibacterial drug rectification so as to improve the rational medi-cation of antibacterial drugs. METHODS:By using the method of retrospective analysis,the antibacterial drug application data in 2011(before rectification and initial stage of rectification),2012(middle stage thereof)and 2013(later stage thereof)were sum-marized,compared and analyzed. RESULTS:After special rectification(Jan. 2011 vs. Dec. 2013),the utilization rate of antibacte-rial drugs in perioperative period for class I incision decreased from 80.42% to 24.49%. That of antibacterial drugs in emergency treatment decreased from 53.79% to 36.23%. The examination rate of microbial samples in inpatients who would use special-grade antibacterial drugs increased from 16.12% to 94.17%. The use intensity of antibacterial drugs by inpatients decreased from 70.28 DDDs/(100 persons·d) to 27.44 DDDs/(100 persons·d). The utilization rate of antibacterial drugs by inpatients decreased from 65.99% to 46.45%. CONCLUSIONS:Special rectification has remarkable effects on rational clinical application of antibacterial drugs. Regulation and evaluation should be strengthened to maintain the effects and continuously improvement should be made.
