ObjectiveTo investigate the objective characteristics of tongue manifestations in patients with coronary heart disease （CHD）. MethodsA total of 315 participants with CHD were recruited in the CHD group， and 211 healthy participants who underwent physical examination were recruited as the healthy control group. In addition， according to the common comorbidities （primary hypertension， carotid atherosclerosis， type 2 diabetes mellitus， fatty liver， hyperlipidaemia， heart failure， and cerebral infarction） in 315 participants with CHD， each comorbidity was classified into a group of comorbidities with that disease and a group of non-comorbidities. Tongue images were captured using a TFDA-1 tongue diagnostic instrument to characterise the tongue body （TB） and tongue coating （TC）， comparing the RGB， HIS， and Lab colour spaces in the chromaticity index （R， red； G， green； B， blue； H， hue； I， intensity； S， saturation； L， lightness； a， red-green axis； b， yellow-blue axis）， the tongue coating thickness index （per-All）， contrast （CON）， angular second moment （ASM）， entropy （ENT）， and mean （MEAN） in texture metrics. ResultsCompared with the healthy control group， the characteristic indexes of tongue body in CHD group showed lower TB-R， TB-G， TB-B， TB-I， TB-L and higher TB-H， TB-b； and the characteristic indexes of tongue coating in CHD group showed lower TC-R， TC-B and higher TC-CON， TC-MEAN， TC-H， TC-b （P＜0.05 or P＜0.01）. Compared with non-combined primary hypertension group， CHD combined primary hypertension group showed higher per-All， TB-G， TB-L， and lower TB-a， TC-a （P＜0.05）； compared with the non-combined carotid atherosclerosis group， CHD combined carotid atherosclerosis group showed higher TB-CON， TB-ENT， TB-MEAN， and lower TB-ASM （P＜0.05 or P＜0.01）； compared with the non-combined type 2 diabetes mellitus group， CHD combined type 2 diabetes mellitus group showed lower per-All and higher TB-H （P＜0.05 or P＜0.01）； compared with the non-combined fatty liver group， CHD combined fatty liver group showed higher TB-CON， TB-MEAN， TB-ENT， and lower TB-ASM and TC-S （P＜0.05 or P＜0.01）； compared with the non-combined hyperlipidaemia group， CHD combined hyperlipidaemia group showed lower TB-S and TB-a （P＜0.05）； compared with non-combined heart failure group， CHD combined heart failure group showed lower TB-R， TB-G， TB-I， TB-L， and higher TB-a （P＜0.05 or P＜0.01）； compared with non-combined cerebral infarction group， CHD combined cerebral infarction group showed higher TC-CON， TC-ENT， TC-MEAN， and lower TC-ASM （P＜0.05 or P＜0.01）. ConclusionCompared to healthy individuals， patients with CHD tend to have darker tongue colours and rougher TC textures. Compared with non-comorbidity participants， those with primary hypertension tended to be lighter tongue colour and thicker tongue coating， those with carotid atherosclerosis had paler tongue body， those with type 2 diabetes mellitus had thinner tongue coating， those with fatty liver disease had paler tongue body and whiter tongue colour， those with hyperlipidaemia and heart failure had paler tongue colour， and those with cerebral infarction had rougher tongue texture.

Résumé
Objective To explore the effect of glutamine on immune function of rat with obstructive jaundice and its possible mechanism. Methods Fifty male Wistar rats were randomly divided into three groups: Control group (n=10), obstructive jaundice group (n=20) and glutamine treatment group (n=20). The serum concentration of TNF-?, IL-10 was detected by using radioimmune method. Liver function was measured through automated biochemistry analyzer. The animal model of obstructive jaundice was established by ligating the rat's common bile duct. Bacteria cultures were performed with the rat's tissues of lung, spleen, liver and kidney respectively. Resu- lts Compared with control group, obstructive jaundice group showed statistically lower serum level of TNF-?, and statistically higher serum level of IL-10, TBIL, ALT and AST during the first and the second week after ligation of common bile duct. During the first and second week after administration of glutamine, the serum TNF-? of glutamine treatment group was statistically higher than that in control group and obstructive jaundice group. Meanwhile, glutamine treatment group showed statistically lower serum level of IL-10, TBIL, ALT and AST than obstructive jaundice group. There were statistically less bacteria translocations in glutamine treatment group than those in obstructive jaundice group. Conclusion Glutamine can increase the immune function by changing serum concentration of TNF-?, IL-10 and decrease the bacteria translocation.
