Chinese Journal of Nosocomiology 1994;0(01):-
OBJECTIVE To investigate the role of IL-16 in the process of airway inflammation of chronic obstructive pulmanory disease(COPD) patients.METHODS The sputum of 60 COPD elderly was collected in the period of exacerbation and alleviation.Serum level of IL-16 was tested using ELISA.RESULTS IL-16 level was higher in severe [(4240.7?296.36,1737.59?367.81)pg/ml] and moderate [(3125.87?286.35,1564.34?478.99)pg/ml] COPD patients in exacerbation and alleviation period than in mild patients(173.75?31.26,129.27?23.89)pg/ml and IL-16 level decreased after effective therapy.CONCLUSIONS IL-16 participates in the procedure of airway inflammation.Surveillence of dynamic variation of IL-16 can reflect the severity of airway inflammation,but it can not offer more diagnostic value.

China Pharmacy 2001;0(12):-
OBJECTIVE:To prepare different compound scald preparations and to investigate their repairing effects for deep Ⅱ? scald in rabbits.METHODS:The deep Ⅱ? scald model was established in depilated rabbits by infrared radiation.Then the rabbits in the trial groups were treated with the same drug at different dosage and different forms of medication:compound scalded gels,compound scalded ointments and the compound scalded films,with Moist Exposed Burn Ointment as positive control and 0.9% NaCl aqueous solutions blank.After a certain time of treatment,the contraction of the scald skin was observed and the average value of the diameter of the scald skin was calculated.RESULTS:In three trial groups and Moist Exposed Burn Ointment positive control group,no scald infection occurred,and the healing surfaces of the scalds were all smooth and even.However,the healing time was different between 3 trial groups and Moist Exposed Burn Ointment positive control group,with compound scalded gels showing the best efficacy in that the scald surfaces were free from infection,the healing surfaces were smooth and even,and the contracted diameter of the scalded skin was significantly lower than in other groups,showing significant differences as compared with other groups(P
4.Treatment of serious attrition with defect of dentition in old people
Journal of Practical Stomatology 2001;0(01):-
Objective:To summarize the expierence in the prostheti c treatment of serious attrition with defect of dentition in old people. Methods: Removable denture with occlusal pad was one timely prepa red for 32 people aged 58~80 years old with serious attrition and defect of de n tition. 6 of the patients had temporomandibular disturbance (TMD). The time of f ollow up visit of the patients ranged from 2.5 months to 5 years.Res ults: The masticatory function of the patients was improved obviousl y .Unilateral mastication was achieved. The symptom of articulation was all rel ieved.The occlusal relationship was not changed or occlusal vertical dimension ( OVD) was appropriately increased in the patients without TMD. The symptom of TMD did not appear after using denture in patiends with TMD.Conclu sions:During occlusal reconstruction in old people with serious attri tion and defect of dentition, the recovery of OVD and occlusal relationship is v ery important.

Chinese Journal of Clinical Infectious Diseases 2009;2(1):24-29
Objective To investigate the effect of DSG biologic information infrared liver disease therapy instrument(BILT liver disease therapy instrument)on liver microcirculations in mice.Methods Liver fibrosis was induced in 40 SPF mice which were randomized into 4 groups:without irradiation group,coht light irradiation group,infrared light irradiation group and BILT group(10 in each group).Twenty healthy mice were taken as the control.Liver blood flow of each group was observed by laser-Doppler flow instrument,and blood flow rate of liver microcirculation in each group was observed by intravital microscopy.Pathological examination and serum biochemistry were also performed.Results In fibrosis mice,the liver blood flow in average of BIUF group Was higher than that of without irradiation group(P=0.004),while comparing with without irradiation group there were no significant differences in liver blood flows of the cold light irradiation group and infrared light irradiation group(P=0.713 and 0.465).Red blood cell velocity of microvessels in average of the healthy group(without irradiation)wag higher than that in the without irradiation group offibrosis mice(P=0.001),and it in the BILT group(fibrosis mice)Was also higher than those in other groups of fibrosis mice(P=0.004,0.020 and 0.030).For fibrosis mice,the average AST in BILT group was lower than that in the without irradiation group(P=0.027),and the difference in hydroxyproline(Hyp)levels between the groups was not of statistical significance(P=0.433).Conclusion BILT liver disease therapy instrument can improve the liver microcir-culation,reduce AST level and improve liver pathological state in mouse with fibrosis.
10.Voltage-dependent calcium channel(VDCC)LTP and N-methyl-D-aspartate(NMDA)receptor channel LTP
International Journal of Biomedical Engineering 2008;31(2):74-77
Long-term potentiation(LTP)is a typical model of synaptic plasticity which has great relationship with learning and memory mechanisms:The induction of LTP depends on the activation of the calcium channels and LTPs generated by calcium ions influx through different channels play different roles in memory.This paper reviews the progress of the research on LTPs induced by activations of N-methyl-D-aspanate receptor(NMDAR)channels and voltage-dependent calcium channels(VDCC).Finally,it gives an example of new forms of low frequency stimulation for induction of LTP.
