OBJECTIVE:To explore how to establish good procedure,system and mode of drug management,dispensing and application,in order to provide reference for risk management and rational use of rabies vaccine. METHODS:The use of rabies vaccine and storage temperature monitoring in our hospital during 2013-2014 were analyzed statistically,and risk management and use of rabies vaccine in our hospital were analyzed,and management measures and attentions were put forward. RESULTS:The amount of vaccinum rabiel (Vero cell) and human rabies immunoglobulin in our hospital were increased in 2014,compared to 2013. The position labeled with #1 in storehouse and that of labeled with #1 and #2 in dispensing store could meet the storage condi-tion of rabies vaccine. Risk management could be carried out in fields of drug requisition,cold chain management,drug manage-ment and drug dispensing. ADR should be paid attention. CONCLUSIONS:It is of significance to develop risk management and ra-tional medication guidance of rabies vaccine.

OBJECTIVE:To optimize the extraction technology of polysaccharides from antlion and explore its effect on im-mune functions of mice. METHODS:Using content of polysaccharides as investigation index,the effects of extracting polysaccha-rides from antlion by water extraction method protease hydrolysis extraction(optimized by orthogonal test using extraction tempera-ture,enzyme dosage,extraction time as indexes),and diluted alkali extraction(optimized by orthogonal test using alkali concentra-tion,extraction temperature,extraction time as indexes)were compared. 128 KM mice were randomly divided into 4 groups,then randomly divided into control group(normal saline),polysaccharides low-dose,medium-dose,high-dose groups(20,40,80 mg/kg),8 in each group,iv in tail vein,0.2 mL/10 g,once a day,for 1 week,which were respectively used to determine the phago-cytosis percentage and phagocytic index of peritoneal macrophages,spleen and thymus index,lymphocyte transformation rate and serum hemolysin levels. RESULTS:The contents of polysaccharides by 3 methods were 14.48%,38.66%,30.62%,respectively. The content of polysaccharides by protease hydrolysis extraction was the highest,the optimal extraction technology were as follows as using 100 μg/g papain extracting 3 h under 40 ℃. Compared with control group,phagocytosis percentage,phagocytic index, spleen index in polysaccharides low-dose,medium-dose,high-dose groups were significantly increased (P<0.05),thymus index was significantly decreased(P<0.05),while lymphocyte transformation rate had no significant changes(P>0.05);serum hemoly-sin in polysaccharides medium-dose group was significantly increased (P<0.05). CONCLUSIONS:Protease hydrolysis extraction is suitable for the extraction of polysaccharides from antlion,the optimal technology is reliable. Polysaccharides from antlion show activity in enhancing mice non-specific immunity and humoral immunity.

Objective To investigate the influence of heme oxygenase-1 (HO-1) on rat renal tubular epithelial cell apoptosis induced by albumin and the possible mechanism. Methods The renal tubular epithelial cells (NRK-52E) were cultured in DMEM/F12 1:1 medium as normal control group; NRK-52E cells were cultured with 30 g/L fat-free bovine serum albumin (BSA) as the BSA control group; NRK-52E cells were cultured with CoPP (Cobalt pretoporphyrin Ⅸ) 5 μ mol/L for 24 hours as the treatment group. MTT assay was used to observe the effects of CoPP on growth inhibition induced by BSA in NRK-52E cells. The effect of CoPP was observed in BSAinduced apoptosis with the fluorescence microscope dyed by AnnexinV-FITC PI. The levels of HO-1, and expression of Bcl-2 and Bax mRNA were detected by reverse transcript polymerase chain reaction (RT-PCR). Results Compared with normal control group, BSA inhibited the growth of NRK-52E cells (P<0.05) and increased cell apoptosis rate (P<0.05). The CoPP pretreatment partially inhibited the BSA-induced apoptosis(P<0.05). Compared with normal control group, HO-1 mRNA expression increased (0.44±0.06 vs 0.39±0.05, P<0.05) in BSA control group. Compared with the BSA control group, the expression of HO-1 mRNA significantly increased after CoPP pretreatment(0.50±0.06 vs 0.44±0.06, P<0.05 ). Meanwhile, BSA increased the expression of Bax mRNA (0.87±0.04 vs 0.67±0.03, P<0.05)and reduced the expression of Bcl-2 mRNA (0.25± 0.04 vs 0.42±0.02, P<0.05 ). CoPP could inhibit the effect of BSA (Bax mRNA: 0.75±0.07, Bcl-2 mRNA: 0.36±0.03, P<0.05, respectively). Conclusions BSA can increase the apoptosis rate significantly and regulate the expression of apoptosis associated proteins in mRNA level directly. CoPP inhibits these changes, which provides evidence to support the essential role of HO-1 in cytoprotective function .

Objective To investigate the relationshipbetween glucose fluctuation and the degree of nervous dysfunction of the acute cerebral infarction in patients with type 2 diabetes mellitus.Methods 30 patients with ACI and T2DM were chosen as observation group and 30 patients with T2DM without ACI as the control group.Glucose fluctuation in all patients were monitored for 72h with the continuous glucose monitoring system(CGMS).High frequency ultrasound was used to detect the carotid intima-media thickness (IMT).The levels of blood lipids,glycosylated hemoglobin (HbA1c),homocysteinemia(Hcy) and C-reactive protein(C-RP) were detected in all the patients.The national institute of health stroke scale(NIHSS) was performed.The correlation between NIHSS and other observed factors were analyzed.Results (1)The mean amplitude of glycemic excursions (MAGE),blood glucose standard deviation(SDBG),absolute means of daily differences(MODD),the largest amplitude of glycemic excursions(LAGE),blood lipids,HbA1c,Hcy,C-RP and IMT were statistically significant different between the two groups (all P＜0.05); (2)The MAGE,SDBG,IMT,Hey,C-RP,low-density lipoprotein cholesterol-C (LDL-C),and systolic blood pressure(SBP) were correlated with the NIHSS score (all P＜0.05) ;(3)With NIHSS score as the dependent variable and the indicators above as the independent variables,the multiple stepwise regression analysis showed that the MAGE,IMT,Hcy came into the final equation.Conclusions The blood glucose fluctuation is probably the influential factor on the development of acute cerebral infarction in T2DM patients.Therapy for lowering blood glucose smoothly should be established as soon as possible to recover the nerve function after cerebral infarction and reduce the incidence of stroke recurrence.

Objective To explore the effects of ethyl-3,4 dihydroxybenzoate(EDHB), a prolyl hydroxylase inhibitor, pretreatment on the tubular epithelial cells apoptosis induced by albumin and hypoxia. Methods To investigate the effects of albumin and hypoxia on cells, rat tubular epithelial cells(NRK-52E)were incubated for 24 h in:(1)normoxia(5%CO2);(2)hypoxia(1% O2);(3)albumin(30 g/L)under normoxia;(4)albumin(30 g/L)under hypoxia. To investigate the effects of EDHB pretreatment on cells apoptosis, NRK-52E were incubated in hypoxia for 24 h in:(1)normoxia;(2)hypoxia;(3)hypoxia+albumin(30 g/L);(4)hypoxia+EDHB(500 μmol/L);(5)EDHB pretreatment(albumin 30 min after EDHB). Apoptosis was measured by flow cytometry(AnnexinV-FITC-PI). bcl-2, bax and vascular epithelial growth factor(VEGF)mRNA expression were detected by RT-PCR. VEGF protein expression was detected by Western blotting. Results NRK-52E apoptosis was not significantly different between hypoxia and norraoxia groups(P>0.05), but increased significantly in albumin(30 g/L)under hypoxia group compared with albumin(30 g/L)under normoxia group(37.36%?.95% vs 25.59%?.32%, P< 0.05). There was an increase in bax mRNA expression and a decrease in bcl-2 mRNA expression in albumin(30 g/L)under hypoxia group compared with albumin(30 g/L)under normoxia group(P< 0.05). EDHB pretreatment improved these impairments of albumin(30 g/L)under hypoxia on NRK-52E(P< 0.05). VEGF expression elevated in hypoxia compared with normoxia(P<0.05), decreased in albumin(30 g/L)under hypoxia groups compared with that without albumin groups(P<0.05).EDHB pretreatment significantly improved VEGF expression compared with albumin(30 g/L)under hypoxia group(P <0.05). Conclusion NRK-52E cells apoptosis induced by albumin is accelerated by hypoxia, however partially improved by EDHB pretreatment, probably through the up-regulation of VEGF expression.
