OBJECTIVE:To improve the system of management and maintenance for the purification air-conditioning system in PIVAS,and to further strengthen the management of cleaning environment. METHODS:The cleanness monitoring project of purifi-cation air-conditioning system in PIVAS of our hospital was introduced in terms of temperature and humidity record,pressure differ-ence record,airborne particles detection,settling microbe monitoring report. And the monitoring results were analyzed. RESULTS:The temperature and humidity,pressure difference of clean area in PIVAS of our hospital are both in line with the standard of Phar-macy Intravenous Admixture Quality Management Specification (2010 edition),i.e. temperature at 18-26 ℃,relative humidity of 40%-65%;negative pressure difference between antibiotics,hazardous drug dispensing area and second dressing room are 5-10 Pa. The number of airborne particles (average static particle/m3) at various cleanness degrees in clean area are all in line with the standard of GMP(2010 edition),i.e. maximal allowable number of airborne particles(≥0.5 μm)were 3 520/m3(100 degree);352 000/m3 (10 000 degree);3 520 000/m3 (100 000 degree). The percentage of qualified static settling microbe detection reach 100%in clean area,which is in line with the standard of Settling Microbe Detection Method in Clean Room(Area) of Pharmaceu-tical Industry,i.e. criteria for settling microbe(90 mm)CFU/0.5 h≤1(100 degree);≤3(10 000 degree);≤10(100 000 degree). The percentage of qualified dynamic settling microbe detection is in low level,especially those of dispensing room and secondary dressing room only reaches 80%. CONCLUSIONS:It’s important for effective hospital infection control in PIVAS,the quality im-provement of intravenous injection,the safety guarantee of drug use in patients to further improve standard operation procedure of purification air-conditioning system management and maintenance,and manage and maintain the purification air-conditioning sys-tem completely and scientifically.

A rapid LAMP detection method with primers designed on genus-specific region identified in the gyrA gene was established in this assay. All four Campylobacter jejuni from different sources were detected positive and fourteen non Campylobacter bacteria were negative, which shows excellent specificity of the primers. Compared with plate count and PCR method, the LAMP method and the PCR method had equal sensitivity, which were three orders of magnitude higher than plate count. In this assay, we also found out that the treatment of DNase could reduce the dead bacteria DNA effectively. The LAMP detection on chicken indicated relatively good result on detection of Campylobacter jejuni combining with treatment of DNase.

OBJECTIVETo explore the possibility of brain damage induced by several anti-epileptic drugs (AEDs) at therapeutic level to immature brain of rat.
METHODSTotally 160 healthy Spraque-Dawley (SD) rats selected for the study were divided into infant and adult groups. Each age group was treated with phenobarbital (PB), clonazepam (CZP), valproic acid (VPA), topiramate (TPM) or normal saline respectively for 2 or 5 weeks with 8 rats in each group. The steady-state plasma concentrations of AEDs at the experimental dosage were coincided with the range of clinical therapeutic concentrations. Drug levels in plasma were determined by fluorescence polarization. Body and brain weights were measured when the rats were sacrificed. Histological studies on the tissues of frontal lobes and hippocampus were performed by Nissl staining. And ultrastructural changes of brain were observed by the transmission electron microscopy. Plasma neuron-specific enolase (NSE) was determined by ELISA. Expression of apoptosis-related proteins Bcl-2 and Bax in neurons was detected by immunohistochemistry. Neuronal apoptosis was detected by terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling (TUNEL).
RESULTS(1) There were no significant differences in brain weight among all adults groups. While remarkable reduction of brain weight was observed in immature rats exposed to CZP or PB (P < 0.01) for long term. (2) Significant neurodegeneration, neuronal necrosis and decrease in the number of neurons can be observed in the immature rats exposed to CZP or PB for long period. (3) For immature rats, concentration of plasma NSE was increased even after short-term treatment with PB [(8.84 +/- 2.10) nmol/L] compared with control group [(6.27 +/- 1.27) nmol/L] (P < 0.01). And it was increased in immature rats exposed to CZP [(8.15 +/- 1.67) nmol/L] or PB [(8.07 +/- 1.27) nmol/L] for long term compared with controls [(6.02 +/- 1.20) nmol/L] (P < 0.01). But there were no significant differences between AEDs-treated adult rats and control rats. (4) The expression of Bcl-2 and Bax protein in mature brain did not change at therapeutic level. In contrast, expression of Bax protein in the frontal lobe was increased significantly in immature rats receiving CZP and PB for long period compared with control. (5) The number of TUNEL positive cells in immature rats exposed to CZP or PB for long term was obviously increased.
CONCLUSIONSPB and CZP may result in remarkable histological abnormalities, neuronal apoptosis and necrosis in immature brain. The brain damage induced by PB was more serious and persistent than that induced by CZP.

OBJECTIVE:
To set up a prostate cancer cell line in which beta-catenin expression is stably suppressed and to investigate the role of Wnt/beta-catenin signaling pathway in prostate tumorgenesis.
METHODS:
We select 3 sites in the complete coden sequence region of beta-catenin gene as the RNAi targets, ligated the annealed double pre-DNA strands into the retroviral vectors pSUPER-retro and transfected them into the packaging cells PA317, and then collected supernatant with retrovirus to infect DU145. After selection by puromycin and culture expansion, the stable cell clones were attained. Expression of the 2 target genes of Wnt/beta-catenin signaling pathway cyclinD1 and c-myc, was detected in the beta-catenin RNAi cells by Western blot. The effect of suppressing beta-catenin by RNAi on cell proliferation was quantified by methylthiazoletetrazolium (MTT) assay.
RESULTS:
Western blotting and RT-PCR showed that the expression level of beta-catenin in the 2 stable cell clones apparently decreased. CyclinD1 and c-myc expression decreased in the beta-catenin RNAi cells. MTT showed that the cell number of beta-catenin expression suppression cell clones decreased significantly (P < 0. 05), suggesting the cell proliferation was prevented.
CONCLUSION
The beta-catenin gene stable suppression cell line was successfully established.
