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.

OBJECTIVETo explore the changes in the mRNA expression of adiponectin (Adp), adiponectin receptors(AdpR), and leptin in different adipose tissues of Wannanhua pigs at different stages of development, and their sexual dimorphism.

METHODSFive Wannanhua boars and five Wannanhua gilts were sampled at birth, 30, 45, 90, and 180 days of age respectively. The delta delta Ct relative quantification real-time PCR was used to detect the transcription levels of Adp, AdpR1, AdpR2, and leptin mRNAs in subcutaneous (SC) and perirenal (PR) adipose tissues, and beta-actin were used as internal standards.

RESULTSThe expression level of Adp, AdpR1, AdpR2, and leptin mRNA in SC and PR adipose tissue were changed with age significantly (P < 0.01). In general, Adp mRNA expression in SC adipose tissue was significantly lower than that in PR adipose tissue (P < 0.05), while AdpR1, AdpR2, and leptin mRNA expression in SC adipose tissue were significantly higher than those in PR adipose tissue (P < 0.05 or P < 0.01). Although the sexual dimorphism were found in apart genes or apart days of age, Adp, AdpR1, AdpR2, and leptin mRNA expression both in SC adipose tissue and PR adipose tissue had no significant differences between Wannanhua gilts and boars in general. Significant positive correlation was found between Adp and AdpR1, AdpR2 (P < 0.05 or P < 0.01), and significant negative correlation was found between Adp and leptin (P < 0.05) in SC adipose tissue and PR adipose tissue respectively (P < 0.05).

CONCLUSIONThe expression of Adp, AdpR1, AdpR2, and leptin mRNA in adipose tissue of Wannanhua pigs followed specific developmental patterns and tissue specificity. Adp correlated with its receptors.

Objective To explore the approach and early effects of endovascular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Methods Six cases with portal vein stenosis of cancerous thrombus,which caused by primary hepatic carcinoma(5 cases)and eholangiocarcinoma(1 case)and the severity of stenosis showed on contrast enhanced CT were more than 75% or occluded,were performed percutaneous transhepatie or transsplenic portography.FLUENCY~(TM) endovascular stent-graft(10 mm diameter)was placed at the position of stenosis after gastroesophageal varices embolization.Portal pressure was measured pre-and post-deployment.Results Stents were successfully placed in all patients.The average portal pressure decreased from 50.7 cm H_2O(1 cm H_2O = 0.098 kPa)to 41.3 cm H_2O after endovascular stent-graft deployment.The restenosis were found in 2 cases after one month.Haematemesis and refractory aseites appeared in one case respectively,the other 4 cases showed no significant symptoms above caused by portal hypertension.Conclusion It is safe and feasible for endovaseular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Selecting the suitable indications,the symptoms of portal hypertension can be controlled effectively.

Objective To search for a method to differentiate the peripherial and central part of spinothalamic tract. Methods The subjects were set on supine position. A heat-foil technology was used to elicit pain and contact heat evoked potentials (CHEP). Thermal stimuli were sent at 54.5 ℃ to three body sites: the dorsum of hand, proximal volar foratm and C7. CHEP was recorded from Cz and Pz. The main components of CHEP were watched. Nerve conduction velocity was calculated. Results Two components, Cz/N550 and Cz/P750, were found in the evoked potentials. The latency of CHEP were different when the dorsum of hand, proximal volar forarm and C, were stimulated respectively. There was no statistical difference between males and females. Nerve conduction velocity of the fiber was (12.9±7.5) m/s which was corresponded to that of AS fiber. Conclusion It is suggested that pain evoked potential could be elicited reliably,the stimulation of C7 would help differentiate the lesion of peripherial and central part of spinothalamic tract.
