Geographic tongue, also called benign migratory glossitis, is a common and superficial benign inflammatory disorder that affects the tongue epithelium. The majority of geographic tongue lesions typically manifest as irregular central erythematous patches. These lesions, which are caused by the loss of filiform papillae, are defined by an elevated whitish band-like border that can change location, size, and pattern over a period of time. Histological observations of the oral mucosa affected by geographic tongue revealed nonspecific inflammation. Some reports described cases of migratory stomatitis, wherein lesions simultaneously manifested on the extra lingual oral mucosa. This condition is also called ectopic geographic tongue, which is clinically and histologically similar to the type normally confined to the tongue. In most cases, patients are asymptomatic and do not require treatment. The condition may spontaneously exhibit periods of remission and exacerbation with good prognosis. The specific etiology of geographic tongue remains unknown. Geographic tongue is age-related and is prevalent among young individuals. Various etiological factors that have been suggested in literature include immunological factors, genetic factors, atopic or allergic tendency, emotional stress, tobacco consumption, hormonal disturbances, and zinc deficiency. Geographic tongue may coexist with other disorders, such as fissured tongue, psoriasis, diabetes mellitus, gastroin- testinal diseases, burning mouth syndrome, and Down syndrome. Experts currently disagree on whether geographic tongue is an oral manifestation of psoriasis. Moreover, some scholars suggest that geographic tongue is a prestage of fissured tongue. The objective of this review is to summarize current research on risk factors of geographic tongue.

Aim To investigate the effect of transduct-ed-hemeoxygenase-1 ( HO-1 ) protein on brain ischemi-a-reperfusion ( I/R ) rat hippocampal neurons injury. Methods 11 R ( arginine residues )-fused HO-1 pro-tein was established and 50 male Mongolian gerbils were randomly divided into 5 groups ( n=10 ):I/R ( control group ) , I/R + 5 mg · kg-1 saline group ( group S ) , I/R + 5 mg · kg-1 11 R group ( group R), I/R + 5mg·kg-1 11R-HO-1 group (group H1) and I/R + 25 mg · kg-1 11 R-HO-1 group ( group H2). For I/R experiments, ischemia was induced for 5 min by occluding the common carotid arteries bilater-ally with aneurysm clips under Ketamine anesthesia. The experiment was conducted after the neurons were intraperitoneally injected with 5mg·kg-1 saline,11R , 11R-HO-1,or 25mg · kg-1 11R-HO-1 for 3 h. The rats were killed after 24h of reperfusion. Hippocampus was removed immediately for determination of cAMP level, neuronal apoptotic rate, and expression of HO-1 and Caspase-3 protein, mitochondria was observed un-der electron microscope. Results Among group C, group S and group R,there were no differences in the expressions of HO-1, Caspase-3 protein, cAMP level , neuronal apoptotic rate and mitochondria damage ( P>0. 05). Compared with group C, group S and group R, the expression of HO-1 protein was up-regulated, the expression of Caspase-3 protein was down-regula-ted, cAMP level increased, the apoptotic rate was sig-nificantly decreased and mitochondria damage de-creased in group H1 ( P < 0. 01 ) . Compared with group H1 , the expression of HO-1 protein was up-regu-lated, the expression of Caspase-3 protein was down-regulated, cAMP level increased, the apoptotic rate was significantly decreased and mitochondria damage decreased in group H2 ( P <0. 01 ) . Conclusion Transducted-HO-1 protein can attenuate brain ischemi-a-reperfusion rat hippocampal neurons injury.

Objective To explore the application of furosemide/hydrochlorothiazide load test in clinical classification of Bartter syndrome and Gitelman syndrome and the significance of selecting target genes. Method The clinical features, biomarkers, the furosemide/hydrochlorothiazide load test, and gene detection in 5 patients with Bartter syndrome and Gitelman syndrome were retrospectively analyzed during 2012 to 2014. Results All of those 5 patients were manifested low potassium and metabolic acidosis; basis of renin, angiotensin II, and aldosterone were elevated. The blood pressures were normal. Most of the patients suffered from polydipsia, diuresis, and different degrees of growth retardation. The gene analysis of these 5 patients made the same diagnoses as furosemide/hydrochlorothiazide load test did. Conclusions Furosemide/hydrochlorothiazide load test can make a differentiation of Bartter syndrome from Gitelman syndrome and thus it can guide the selection of targeted gene detection.

[ ABSTRACT] AIM:To investigate the effect of combined treatment with gonadotropin-releasing hormone analogue ( GnRHa) and growth hormone ( GH) on the linear growth in mid-and late pubertal girls at great bone ages with central precocious puberty ( CPP) or early and fast puberty ( EFP) , and to determine the relation between C-type natriuretic pep-tide ( CNP) signaling pathway and the accelerative effect of GH on long bone growth in these girls.METHODS:Twenty-two girls were diagnosed as CPP or EFP, whose bone ages were older than 11.5 years with impaired predicted adult height ( PAH) , and divided into GnRHa treatment group ( treated with GnRHa alone, slow-release of triptorelin 60~80 μg/kg every 4 weeks, im) and combined treatment group ( treated with GnRHa and GH, 1 U/kg GH every week for 6~7 times, sc) .The height, weight and pubertal stage were determined every 3 months.At the beginning and after 6 months of the treatment, the bone age was evaluated and the serum concentrations of amino-terminal pro-C-type natriuretic peptide ( NT-proCNP), insulin-like growth factor 1 (IGF-1) and procollagen type 1 amino-terminal propeptide (P1NP) were measured. Height velocity ( HV) , height SD score for bone age ( HtSDSBA ) , PAH and the serum indexes mentioned above were com-pared at the beginning and the end of the treatment.RESULTS: After 6 months of the treatment, HV, ΔHtSDSBA andΔPAH of the girls treated with GnRHa +GH were statistically higher than those of the girls given GnRHa alone ( P <0.01).Serum concentrations of NTproCNP, P1NP and IGF-1 were not significantly different between the beginning and the end of the 6-month combined treatment.The girls treated with GnRHa alone showed a significant decrease in both serum NTproCNP and P1NP levels (P<0.05) and no significant change of serum IGF-1 level after 6 months of the treatment. CONCLUSION:In the CPP or EFP girls who are in mid-and late puberty and at great bone ages, the combined treatment with GnRHa and GH may accelerate linear growth and improve predicted adult height.This effect of GH is not attributed to the change of serum IGF-1 level, and may be related in part to the acceleration of CNP-mediated long bone growth.

Objective To explore the relationship between adrenarche and gonadarche.Methods Total 49 idiopathic central precocious puberty(ICPP)girls,whose serum dehydroepiandrosterone sulfate(DHEAS)Z scores for chronological age were higher than+2 s at diagnosis.were enrolled.Physical examinations during pubertal stage were repeated at 3-6 months intervals,and serum DHEAS levels were monitored yearly within an average period of 4.08 years.Of them,16 girls were followed up until more than one year after discontinuation of gonadotropin-releasing hormone analogue(GnRHa)treatment.Results Before GnRHa treatment,these49 girls presented a younger average age at attainment of pubic hair stage2(PH2)and pubic hair stage3(PH3)than normal(8.07 years vs 11.16 years,8.82 years vs 12.40 years respectively).During GnRHa treatment,the intervals between PH2 and PH3,PH3 and pubic hair stage4(PH4),breast stage 2(B2),and PH2 were longer than normal(1.69 years vs 0.83 years,1.64 years vs 0.60 years,and3.62 years vs 0.76 years respectively).The intervals between PH2 and PH3,as well as B2 and PH2 during GnRHa treatment were also longer than that before GnRHa treatment(1.69 years/35 0.88 years,3.62 years vs 1.13 years respectively).The serum DHEAS Z scores decreased during GnRHa treatment,and increased significantly after GnRHa cessation.Conclusion Gonadarche after age of 6-year-old may lead to earlier adrenarehe.GnRHa treatment might slow down the progression of adrenarche and suppress the hypothalamuspituitary-gonadal axis.
