OBJECTIVE:To study the antioxidant effects of Scutellaria baicalensis(SBE)on the model mice with Alzheimer’s disease. METHODS:All mice were treated by D-gal (150 mg/kg) and NaNO2 (100 mg/kg) for 60 d to reproduce the AD model mice,ip,once a day. Totally 60 mice were randomly divided into normal control group(isovolumetric sodium chloride injection), model group (isovolumetric sodium chloride injection),estradiol (0.4 mg/kg) group,and SBE high,medium and low doses (500,250 and 125 mg/kg). The mice were intragastrically administrated while modeling except normal control group,once a day, for continuous 60 d. The superoxide dismutase(SOD),catalase(CAT)activities and malondialdehyde(MDA)content in brain tis-sue ,and glutathione peroxidase (GSH-Px) activity in serum of mice were determined. RESULTS:Compared with normal control group,the SOD,CAT activities in brain tissue,and GSH-Px activity in serum of mice in model group were decreased,MDA con-tent in brain tissue were increased,with significant difference(P<0.01 or P<0.05);compared with model group,the SOD,CAT activities in brain tissue and GSH-Px activity in serum of mice in SBE high and medium dose groups were increased,MDA content was decrease,with significant difference (P<0.01 or P<0.05). CONCLUSIONS:SBE can enhance the antioxidant capacity in AD model mice by a mechanism that may be related to the improvement of related oxidation indicators’levels.

Objective To discuss the role of platelet-actived factors and hepatic and renal function in the development of pre-eclampsia and eclampsia by detecting the levels of the GP Ⅱb/Ⅲa in the blood, Pt and hepatic and renal function of the patients with pre-eclampsia and eclampsia. Method GP Ⅱb/Ⅲa, Pt and hepatic and renal function were measured in the normal non-pregnancy women, normal late-pregnancy women and pre-eclampsia and eclampsia women. Results The level of GP Ⅱb/Ⅲa in patients with severe pre-eclampsia and eclampsia was higher than that in non-pregnancy, normal late-pregnancy and mild pre-eclampsia (P<0.01). The count of Pt in patients with severe pre-eclampsia and eclampsia was lower than that in non-pregnancy, normal late-pregnancy and mild pre-eclampsia (P<0.01). Except ALB, the hepatic and renal function had significant difference among severe pre-eclampsia and eclampsia, normal late-pregnancy and mild pre-eclampsia. Conclusion Detecting the GP Ⅱb/Ⅲa, Pt and hepatic and renal function have clinical significance in severe pre-eclampsia and eclampsia.

Objective To investigate the effects of epidural ropivacaine block combined with propofol intravenous anesthesia on CaMKⅡ and ERK1/2 total protein (T-CaMKⅡ and T-ERK1/2) and phosphorylation(p-CaMKⅡ and p-ERK1/2) levels in the hippocampus and cortex of rats.Methods Rats were randomly assigned to three groups: group P(control,propofol intravenous anesthesia),group PS(propofol and epidural normal saline) and group PR(propofol and epidural 0.5% ropivacaine).Anesthesia were performed in 72 h after epidural catheter placement.The rats in group PR received 70 μL of 0.5% ropivacaine to achieve epidural block.1% propofol was infused through rats caudal vein.Propofol dosage for anesthesia induction was 12 mg/kg,for anesthesia maintenance was 40 mg/(kg·h).Before the rats were decapitated,the depth of anaesthesia was assessed as either light anesthesia or deep anesthesia by checking of pinch withdrawalreflex,eyelid reflex and spontaneous rapid whisking of the vibrissae after propofol continuous infusion for 1 h.T-CaMKⅡ/T-ERK1/2 and p-CaMKⅡ/p-ERK1/2 in hippocampus and frontal cortex were examined by Western blot.Results 7 rats were assessed as light anesthesia and one rat as deep anesthesia in group P;6 rats were assessed as light anesthesia and 2 rats as deep anesthesia in group PS;in group PR,1 rat was assessed as light anesthesia and 7 rats as deep anesthesia.Significant differences were seen among three groups (P<0.05).In hippocampus of rats,p-CaMKⅡ(Thr286)43.7%±8.8% and p-ERK1/2 32.4%±7.9% in group PR were significantly lower than those in group P (100%,P<0.05).Conclusions Epidural ropivacaine block may strengthen the depth of anesthesia achieved with propofol intravenous anesthesia.The decrease of p-CaMKⅡ(Thr286) and p-ERK1/2 in hippocampus of rats may explain the effects of epidural block.

Aim To investigate the relationship be-tween the depression-like behaviors of rats induced by chronically unpredictable stress( CUS) and the protein expression of tumor necrosis factor alpha( TNF-α) , in-dole-2 , 3-dioxygenase ( IDO ) and 3-hydroxyl amino acid oxygenase( HAAO) . Methods Thirty male Spra-gue Dawley( SD) rats were randomly divided into con-trol group and model group. CUS plus solitary condi-tion were used to establish the depression model. The open field test ( OFT ) and the force swimming test ( FST ) were used to evaluate the depression-like behaviors of rats ;Western blot was used to determine the protein expressions of TNF-α, IDO and HAAO in the prefrontal cortex and hippocampus of rats. Results Model group rats showed obvious depression-like be-haviors with increasing immobile time in FST ( P <0. 01) and decreasing locomotive activity in OFT( P<0. 01 ) , and up-regulating the protein expression of TNF-α, IDO and HAAO in the prefrontal cortex and hippocampus significantly ( P <0. 05 ) , compared with control group rats. Conclusion The depression-like behaviors of rats induced by CUS may be associated with the activation of IDO-HAAO pathway mediated by TNF-α.

OBJECTIVE:To explore the role of clinical pharmacists in tumor pain management for patients receiving tumor pain palliative radiotherapy. METHODS:In prospective randomized controlled study, 60 patients with tumor pain who received palliative radiotherapy in radiotherapy department of our hospital from June 1,2013 to May 31,2014,according with the selection criteria,were randomized into observation group(30 cases)and control group(30 cases). Clinical pharmacists participated in the treatment of observation group;provided pharmaceutical care for doctors;and recorded drug treatment,pain evaluation,medica-tion compliance,Karnofsky Performance Status(KPS)and quality of life(QOL)of 2 groups. RESULTS:On the 5th day,the pain remission rate of observation group reached 63.3%,and was significantly higher than that(36.7%)of control group(P<0.05). 1 month treatment later,pain remission rate of 2 groups reached 70% and 80%,respectively (P>0.05). At the same time,KPS, QOL and medication adherence were all improved significantly,compared with before treatment(P<0.01 or P<0.05),and medi-cation adherence of observation group was obviously better than that of control group(P<0.01). CONCLUSIONS:The participa-tion of clinical pharmacists in the pain management can obviously improve medication compliance,relieve pain more effectively, and promote rational drug use.

Aim To study the role of histone acetyla-tion and its involvement in the depression-like behav-iors of rats induced by chronic unpredictable stress (CUS ). Methods Thirty male Sprague Dawley (SD ) rats were randomly divided into control group and model group.The method of solitary condition with CUS for consecutive 28 days was used to establish the rat depression model.The open-field test (OFT)and the forced swimming test (FST)were used to evaluate the depressive behaviors of rats;the real time PCR was used to detect the change of HDAC2 mRNA, and Western blot was used to determine the protein expres-sions of H3,H4,acH3 and acH4 in the prefrontal cor-tex and hippocampus of rats.Results Model group showed obvious depression-like behaviors with decrea-sing locomotive activity in OFT (P <0.01 )and in-creasing immobility time in FST (P<0.01),up-regu-lating the mRNA and protein expression of HDAC2 (P<0.0 1 ),and down-regulating the protein expression of acH3 and acH4 (P<0.01)in the prefrontal cortex and hippocampus significantly,compared with control group.Conclusion The mechanism of depressive be-haviors of rats induced by CUS may be associated with down-regulating the level of histone acetylation modifi-cation.
