OBJECTIVE:To study the effects of Xingnaojing injection on the expressions of both the protein of IL-1? and the mRNA in the experiment intracerebral hemorrhage rats.METHODS:Referenced by Zou's method and Rosengerg method,rat intracerebral hemorrage model was established and the model rats were then divided into normal group,model group and Xingnaojing group.The pathological changes in all the groups were observed and the expressions of the protein of IL-1? and the mRNA were detected after medication.RESULTS:In Xingnaojing group as compared with model group,the cells arranged regularly,the edema degree was lessened,the inflammatory cells were less;the disorganization of plastiosome was less severe,synaptic structure was clearer.The expressions of both the protein of IL-1? and the mRNA were all lower than in the model group.CONCLUSION:Xingnaojing injection can relieve the cerebral edema and inhibit the expression of IL-1? of the brain tissue surrounding the hematoma in intracerebral hemorrhage rats.

Objective To investigate the levels of complement and activated complement factors in peripheral blood and skin in patients with psoriasis and their significance in the development of psoriatic lesion.Methods Enzyme linked immunosorbent assay (ELISA) and immuno turbidi metric analysis were used to determine the levels of C3d, sC5b-9, C3 and C4 in sera from 57 patients with psoriasis vulgaris.Immunohistochemistry was employed to assess in situ expression of SC5b-9 in lesional and non lesional skin of 37 patients.Results There was a significant decrease of C3 and C4, and increase of C3d and sC5b-9 in patients with psoriasis in comparison with those of normal controls (t=10.88～ 24.80, P<0.01).The levels of C3 and C4 were significantly lower, while the levels of C3d and sC5b-9 were significantly higher in progressive stage than those in static stage (t=4.55～ 6.77,P< 0.01).In situ expression of sC5b-9 was significantly higher in stratum corneum and dermo epidermal junction of lesional skin than that in non lesional skin and normal controls (χ2=62.90,45.45;P< 0.01).There was no significant difference of C5b-9 expression in stratum corneum and dermoepidermal junction of lesional skin between progressive and static stage.Conclusions There is significant correlation between the development of psoriatic lesion and local deposit of activated complement factors.

Loss of the ethical basis in the Chinese healthcare reform is embodied in a number of noticeable questions arising during the reform and development course.We should adhere to correct value orientation and ethical principles in deepening healthcare reform.Each stakeholder inside the reform including government,medical institutions,medical staff,patients and their relatives should take their respective ethical responsibilities.Therefore,the Chinese healthcare industry could develop with Chinese unique characteristics,and the healthcare reform will conduct correctly and continuously.

OBJECTIVE: To investigate the clinical application value of cone-beam CT (CBCT) online correcting technology in volume modulated radiation therapy (VMRT) for nasopharyngeal carcinoma (NPC). METHOD: Fifty NPC patients applying head neck and shoulder thermoplastic body membrane fixing device were eligible for treatment VMRT, these patients would accept a couple of CBCT scanning by on board imager (OBI) in a fixed time each week after initial setup and after online correcting during the first three week for radiotherapy, CBCT images and DRR images constructed by CT simulation were carried out registration,which could calculate the setup errors of initial setup and after online correcting. RESULT: Fifty patients were accepted 150 scanning after initial setup and 150 scanning after online correcting respectively, the errors after initial setup were (-1.24 ± 1.25)mm in X direction, (1.19 ± 1.85)mm in Y direction, (1.49 ± 1.70) mm in Z direction. The setup errors after online correcting were (-0.13 ± 0.29)mm in X direction, (0.10 ± 0.47)mm in Y direction, (0.17 ± 0.36)mm in Z direction. The setup errors after online correcting were significantly lower than the errors after initial setup in X direction (P < 0.05), Y direction (P < 0.05), Z direction(P < 0.05). The M(PTV) value after online correcting were 0.46 mm, 0.53 mm and 0.59 mm in X, Y and Z directions respectively. CONCLUSION The use of CBCT online correcting technology can significantly reduce the setup errors of VMRT for NPC and improve the treatment effect.

Objective To construct pSUPER-SVV vector and obtain its expression in HeLa cells,in order to interfere the expression of survivin.Methods Oligonucleotide sequences specific for survivin were designed for RNA interference(RNAi),after annealed they were ligated to pSUPER.basic vector.After sequencing,the vector of pSUPER-SVV was transfected into HeLa cells by LipofectAmine.The expression of survivin was detected by RT-PCR and FCM.Results The RNAi expression vector of survivin was constructed successfully,which depressed the expression of survivin efficiently.Survivin was significantly depressed on the level of mRNA in HeLa cells compared with the control groups(P

AIM　To investigate the effect of hydroxyl camptothecinum(HCPT) on pharmocokinetics of cyclosprine A(CsA) and the membrane lipid fluidity (LFU)of red cell in rabbits. METHODS　The whole blood concentration of CsA in rabbits was monitored using method of FPIA. The LFU of red cell was measured using method of DPH fluorescence polarization technique. RESULTS　The pharmocokinetic parameters of CsA in group CsA+HCPT such as a,V(c),K12 and CL(s) were significantly lower and T1/2(a) was significantly higher (P<0.05) than in group CsA. The concentration of CsA of group CsA+HCPT was higher after injection 0.25, 0.5 and 1.0 h, but have significantly high at 1.0 h point (P<0.05). After injection 0.5,1.0, 1.5 h the LFU of red cell in group CsA+HCPT was higher than in group CsA (P<0.05). The LFU in group CsA was lower that in control at 0.5,1.0 and 1.5 h point (P<0.05). CONCLUSION　HCPT can enhance the whole blood concentration of CsA in rabbits. CsA administrated with HCPT is feasible.

BACKGROUND:Carboxymethyl chitosan (CMCS),a chitin derivative,has a good application performance that makes it become a safe and effective hemostatic material.OBJECTIVE:To determine the hemostatic effect of CMCS and its biosecurity properties.METHODS:(1) CMCS powder was scattered on the caudal vein and liver wounds of Sprague-Dawley rats,and the hemostatic time was recorded as experimental group,while the time for natural haemostasis of the wound was recorded as control group.(2) CMCS powder was scattered on the tail,femoral artery and liver wounds of ICR mice,and the hemostatic time was recorded as experimental group,while the time for natural haemostasis of the wound was recorded as control group.(3) CMCS,Sodium dodecyl sulfate solution and distilled water were respectively applied on the skin of albino rabbits in a skin irritation test.(4) A delayed-type hypersensitivity test of CMCS was carried out by intradermal injection of CMCS in guinea pigs.(5) An intradermal irritation test was carried out by subcutaneous injection of normal saline containing CMCS and normal saline,respectively.Another intradermal irritation test was carried out by subcutaneous injection of the supernatant of CMCS olive oil extract and olive oil,respectively.RESULTS AND CONCLUSION:(1) Compared with the control group,the hemostatic time for caudal vein and liver wounds were significantly shortened in the Sprague-Dawley rats in the experimental group (P ＜ 0.01).(2) Compared with the control group,the time of hemostasis on the tail,femoral artery and liver wounds was significantly shortened in the ICR mice in the experimental group (P ＜ 0.05 or P ＜ 0.01).(3) The CMCS had no irritation to the skin of albino rabbits and no allergic reaction to the skin of guinea pigs.To conclude,the CMCS has good hemostatic effect on the wound in Sprague-Dawley rats and ICR mice,and has no skin irritation,allergic reactions and intradermal irritation reactions in albino rabbits and guinea pigs,which is a relatively safe hemostatic material.
