Objective To observe the effect of immunity condition and clinical manifestations of children with recurrent oral-ulcer(ROU)treated with aciclovir(ACV) and a-polyresistin.Methods Forty-eight patients with ROU were randomly divided into whole treated group(25 cases)and partial treatment group(23 cases).The changes of their peripheral blood lymphocyte subgroups,before and after treatment,were measured and contrasted to analyze the relationship with curative effect.Results The ratios of CD3,CD4,and CD4/CD8,after the treatment,increased obviously,while CD8 lowered obviously in treatment group(P0.05).The total clinical efficacy rate was 47.82%,moreover the patients were recurrent after 1 year.Conclusions ACV and a-polyresistin,through antivirus and regulating the immunity function get the 96% total clinical efficacy rate,and that controle the recurrent rate.It is superior to the traditional method.

Objective To evoke cerebral potentials by stimulating nociceptive fibers with contact heat evoked potentials stimulator (CHEPS)and estimate the nerve conduction velocities of peripheral nerve fibers mediating these responses.Methods Subjects were set in supine position.A heat-foil technology with a rapid rising speed at 70 ℃/s was used to elicit pain and contact heat evoked potentials(CHEP).Contact heat was delivered via one circular thermode (diameter 27 mm,area 573 mm~2).Thermal stimuli were sent at two intensity levels (49.5 ℃ and 54.5 ℃) to three body sites:thenar eminence,the dorsum of hand and proximal volar forarm.Contact heat evoked potentials were recorded from Cz and Pz.A systemic effect between stimulus intensities and pain rating were observed,the main components of this evoked potential were observed.Nerve conduction velocity was calculated from latency difference of CHEP and center to center distance of distal and proximal stimulus arrays.Results The pain intensity rating was 3.2?0.3 and 4.4?0.5 when thenar eminence was stimulated at the temperature of 49.5 ℃ and 54.5 ℃ respectively;the rating was 6.3?0.8 and 7.2?0.5 when the dorsum of hand and proximal volar forarm were stimulated at the temperature of 54.5 ℃ respectively.Three components,Cz/N550,Cz/P750 and Pz/P1000,were found in the evoked potentials.Nerve conduction velocities of the fibers were (12.9?7.5) and (1.7?0.4) m/s respectively,which were corresponding to those of A8 fiber and C fiber.Conclusions CHEPs can be elicited reliably and stably.Velocities of peripheral nerve fibers demonstrate that A8 fiber and C fiber mediate the response.

Objective To establish the method of contact heat evoked potential(CHEP)and to explore the value of this evoked potential in pain testing of patients with cerebral infarction.Methods A total of 100 healthy volunteers and 30 patients were examined.The healthy volunteers were divided into 3 groups according to the length of their arms:(Group A:56.0～65.0 cm ;Group B :65.5～74.0 cm ;Group C :74.5～83.0 cm).A recently de- veloped heat-foil technique with a rapid temperature rising rate at 70℃/s was used to elicit pain and contact heat e- voked potentials.Contact heat was delivered via one circular thermode(diameter 27 mm,area 573 mm~2)and set at two intensity levels(49.5℃and 54.5℃)to three body sites:the thenar eminence,the dorsum of hand and proximal volar forearm.The subjects were asked to rate the pain with numerical rating scale after each stimulus and CHEP was recorded from Cz and Pz.The association between stimulus intensities and pain rating was explored,the main compo- nents of the evuked potential were watched.CHEP,sensory conduction velocity(SCV)and somatosensory evoked potentials(SEP)were performed in patients with hemi-anesthesia caused by cerebral infarction.Results The pain intensity ratings were 3.2?0.3 and 4.4?0.5 at thenar eminence,5.0?0.7 and 6.3?0.8 at the dorsum of hand and 5.3?0.6 and 7.2?0.5 at the proximal volar forearm when the temperature of 49.5℃and 54.5℃was applied, respectively;Three components,Cz/N550,Cz/P750 and Pz/P1000,were identified in the evoked potentials.Cz/ N550 and Cz/P750 appeared when the dorsum of hand and proximal volar forearm were stimulated.In contrast,Pz/ P1000 could be identified when nociceptors of thenar eminence and proximal volar fbrearm were excited.In the pa- tients with cerebral infarction,CHEP disappeared or became abnormal on one side,while SCV and SEP were normal on that side.Conclusion It was suggested that CHEP could be elicited reliably in the controls.CHEP is helpful in the assessment of analgesia in patients with cerebral infarction.

Objective To evaluate the usage of renoportal anastomosis in the liver transplanta- tion.Method The successful experience about renoportal anastomosis for portal vein reconstruction in liver transplantation was reported,and related literature reviewed.Results Including our case,there have been 13 cases of liver transplantation using renoportal anastomosis for portal vein reconstruction. Among these patients,8 cases were complicated with diffuse portal vein thrombosis,and 10 cases had a splenorenal shunt(spontaneous shunt in 3 and surgical shunt in 7).Complications related to portal vein hypertension occurred in 3 cases(transient ascites in 2 cases and severe digestive bleeding in 1 case)after liver transplantation.There were 3 deaths which were not related to renoportal anastomo- sis.Conclusion Renoportal anastomosis is a safe and feasible technique in liver transplantation for the patients with diffuse portal vein thrombosis or with splenorenal shunt(spontaneous or surgical shunt).

GlyoxalaseⅠthat presents in all human tissues detoxifies α-oxoaldehydes and prevents the formation of advanced glycation end products(AGEs).AGEs and their main precursor namely methylglyoxal(MG)produce cytotoxicity and have extensive relationship with diabetic complications.Therefore,to elevate glyoxalaseⅠactivity may be a new path to release such complications.
