Objective To study the change of bone ?-carboxyglutamic acid containing protein(BGP) in serum of rats at the initial stage of skeletal fluorosis caused by fluoride in coal.Methods SD rats were randomly divided into 6 groups (the number of female and male in each group was the same respectively):the control group,the low-dose fluoride group,the middle-dose fluoride added nutrition group,the middle-dose fluoride group,the high-dose fluoride added nutrition group,the high-dose fluoride group.All rats in the experimental groups were fed on the corn collected from the prevalent areas and contained different contents of fluoride respectively for 90-100 days.Content of fluoride in the urine,bone,kidney,BGP in serum,bone mineral density (BMD)and calcium in the bone and urine were determined.Results The fluorosis of the rats became more serious as fluoride intake increased.On the condition of same fluoride intake,the fluorosis could be relieved if nutrients added.BGP in serum of rats in each experimental groups had a increase trend,at the earlier stage,BGP of the high-dose group was higher than that of the control group (P

Objective To explore the causes of subclinical hypothyrodism in children and the effects of the interventional therapy with thyroixine on the course of it.Methods Two hundreds children with subclinical hypothyroidism were measured for thyroglobulin antibody(TGAb),thyroid microsomal antibody(TMAb) in the blood serum,examined by colord Dopplor ultrasonic,examined by fine needle aspiraton cytology of the throid and measured the rate of 131I absorbed by thyroid in order to find out the causes of the disease.Two hundreds cases were randomly divided into two groups on the base of the cause of diseases,treatment group 100 cases and control group 100 cases.The treatment group were treated by throxine 25-75 ?g/d and the therapeutic dosage were chosen with the normal value of free triiodothyronine(FT3),free thyroxine(FT4)and high sensitive thyrotropin(sTSH) in the blood serum .After one year thyroxine therapy were stopped.Thyroid function was examined 6 months later after stopping the thyroxine.Results Among all of the causes of subclinical hypothyroidism in children,Hasgumoto′s thyroiditis accounts for 56%,simple goiter accounts for 26%,antithyroid drug accounts for 6%,the lack of thyroxine substitution therapy on the hypothyroidism accounts for 5% and undefined causes accounts for 7% .The thyroid function could keep normal for 1 year with an alternative therapy with thyroxine on subclinical hypothyroidism in children.Half a year later after stopping thyroxine,the thyroid function turned normal in most of the children.There were obvious differences in the ratio of cure and the ratio of effectiveness between treatment group and control group (t=20.2,3.2 Pa

Objective To compare the effects on neurobiological factors of attributional retraining group therapy (ARGT) or selective serotonin reuptake inhibitors (SSRI) for major depressive disorder (MDD),anxiety disorder (AD) and obsessive-compulsive disorder (OCD).Methods Outpatients with MDD,AD and OCD were divided into ARGT group (n =63) and SSRI group (n =66) according to the sequence of entering the study.MDD,AD and OCD patients were respectively measured with Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) before and after 8 weeks treatment.All subjects were detected of plasma serotonin,norepinephrine,cortisol and adrenocorticotropic hormone by radioimmunoassay before and after treatment.Results After treatment,HAMD scores of MDD patients were reduced significantly in both ARGT group (t =18.411,P =0.000) and SSRI group (t =20.092,P =0.000) ; HAMA scores of GAD patients were reduced significantly in both ARGT group (t =13.989,P=0.000) and SSRI group (t=15.815,P=0.000) ;Y-BOCS scores of OCD patients were reduced significantly in both ARGT group (t =5.465,P =0.000)and SSRI group (t =4.792,P =0.000).In ARGT group,MDD (t =3.145,P =0.006),AD (t =2.785,P =0.012) and OCD patients (t =2.877,P =0.011) decreased plasma cortisol concentrations significantly.In SSRI group,MDD (t =-2.923,P =0.010) and OCD patients (t =-2.301,P =0.035) improved plasma serotonin significantly and MDD patients (t =-2.333,P =0.033) improved plasma norepinephrine significantly.Conclusion ARGT can modulate plasma cortisol level.SSRI can up-modulate plasma serotonin level.The two therapies take effect by different biological ways.

Mild-symptom erectile dysfunction (MSED) is commonly seen in clinical practice, but receives inadequate attention from both the patients and clinicians. Increasing researches have indicated that MSED is associated with not only unhealthy living habits and psychological factors but also the early progression of endothelial, metabolic and endocrine diseases. The diagnosis and treatment of MSED should be based on the relevant guidelines, with consideration of both its specific and common features. The therapeutic principle is a combination of integrated and individual solutions aimed at the causes of the disease. Drug intervention should be initiated if psychological therapy fails. Negligence of MSED may affect the quality of life of the patients and their partners, and what's more, might delay the management of some other severe underlying diseases. Adequate attention to the early diagnosis and treatment for MSED is of great significance for a deeper insight into the etiology of ED, the prevention of potential cardiovascular and metabolic diseases, and the improvement of the overall health of males.
