Objective: To observe the clinical efficacy of acupoint injection with salmon calcitonin for back pain in elderly patients with primary osteoporosis. Methods: A total of 76 patients were selected and randomly divided into two groups by the random number table method, with 39 cases in the treatment group and 37 cases in the control group, respectively. Patients in both groups received routine anti-osteoporosis treatment. Patients in the treatment group received additional acupoint injection with salmon calcitonin at bilateral Pishu (BL 20) and Shenshu (BL 23), while patients in the control group received additional intramuscular injection with salmon calcitonin. The treatments for both groups were given once a day and lasted for 4 weeks. Visual analog scale (VAS) and Chinese Oswestry disability index (CODI) scores were observed before treatment, after 2 weeks and 4 weeks of treatment, and the use of analgesics during the treatment were recorded. Results: After treatment, the clinical efficacy in the treatment group was more significant than that in the control group (P<0.05). After 2 weeks and 4 weeks of treatment, the VAS scores in both groups showed significant intra-group and between-group differences (all P<0.05), and the CODI scores in both groups showed significant intra-group differences (all P<0.05). After 2 weeks of treatment, the CODI score showed no significant between-group difference (P>0.05). After 4 weeks of treatment, the improvement of CODI score in the treatment group was more significant than that in the control group (P<0.05). During the treatment, 2 cases in the treatment group took analgesics versus 8 cases in the control group, and the result showed a significant between-group difference (P<0.05). Conclusion: For back pain in elderly patients with primary osteoporosis, based on the routine treatment of oral medication, the clinical efficacy of acupoint injection with salmon calcitonin at bilateral Pishu (BL 20) and Shenshu (BL 23) is more significant than that of intramuscular injection. Acupoint injection treatment can improve patients' conditions and reduce the use of analgesics.

Objective To investigate the relationship between the degree of serum cortisol suppression by low-dose dexamethasone (1 mg) and full serum cortisol suppression (suppression rate > 50% ) by high-dose dexamethasone (8 mg) in patients with Cushing syndrome, and to evaluate these tests in Cushing disease. Methods Ninty-one patients with Cushing syndrome were studied retrospectively. The relationship of 20%, 30%, 40%, and 50% cortisol suppression by overnight 1mg dexamethasone with full serum cortisol suppression by overnight 8 mg dexamethasone was analyzed, and the sensitivity and specificity in the diagnosis of Cushing disease were evaluated. Results The degree of cortisel suppression during overnight 1 mg dexamethasone suppression test was correlated with that during overnight 8 mg dexamethasone suppression test (r=0. 649,P<0. 001 ). 30, 22, 13, and 9 patients had greater than 20%, 30%, 40%, and 50% serum cortisol suppression respectively during overnight 1 mg dexamethasone suppression test. Among them, 23 ( 76. 7% ), 20 (90. 9% ), 12 (92.3%), and 9 ( 100.0% )patients had full serum cortisol suppression during overnight 8 mg dexamethasone suppression test. The sensitivity of the cutoff of greater than 20%, 30%, 40%, and 50% serum cortisol suppression for the diagnosis of Cushing disease was 52.8%, 32.7%, 22.6%, and 15.7%, and the specificity was 94.7%, 94.7%, 97.4%, and 97.4% respectively. Conclusions In patients with Cushing syndrome, greater than 20% serum cortisol suppression during overnight 1 mg dexamethasone suppression test is usually associated with full serum cortisol suppression during overnight 8 mg dexamethasone suppression test, and most of them are finally diagnosed as Cushing disease.

Background Streptozotocin (STZ)-induced type 1 diabetic model is an acceptable model and is often used to the study of diabetic retinopathy (DR).However,the model is often established using retinal digest preparation in vitro in albino rats,and therefore it is difficult to evaluate the change of retinal vessels by fundus fluorescein angiography (FFA) in vivo.Recently,pigmented rats are being used as the DR model.But the study on the comparison between albino rat model and pigmented rat model is seldom.Objective This study was to observe and compare the manifestations of FFA and retinal digest preparation in early diabetic pigmented diabetic rat and albino diabetic rat,and to select the right model of DR using FFA.Methods Type 1 diabetic models were induced in 15 six-week-old health male BN rats and 15 six-week-old health male SD rats by the injection of STZ (55 mg/kg) via tail vein.The models were thought to be successful in the rats with the blood glucose level ≥ 16.7 mmol/L.The right eyes of the rats were extracted 6 weeks after injection of STZ.Lens were examined by slit lamp microscope.Retinal vascular changes were examined by fundus photography,FFA and periodic acid Schiff staining of retinal digest preparation.The manifestations of FFA and retinal digest preparation were contrasted between BN rats and SD rats.The number of eyes with lens opacification was compared by Chi-square test and the ratio of vascular endothelial cells and perithelial cells (E/P) was compared between BN rats and SD rats.The use and care of experimental animals complied the Statement of Ethic Committee of Tianjin Medicine University.Results Six weeks after injection of STZ,11 BN rats and 10SD rats were included in this study.The blood levels were (24.73±2.98) mmol/L and (22.36±3.65) mmol/L in BN rats and SD rats,respectively,without significant difference between the 2 types of rats (t =7.873,P＞0.05).Lens opacification occurred in 6 BN rats and in 5 SD rats (P=0.717).FFA showed the clear retinal vascular under the brown background.Evident vessel disorder and fluorescence leakage like background stage of DR were seen in 9 eyes.However,in the SD rats,retinal vessel abnormality could not exhibited owing to the interference of choroid fluorescent light from choroidal vessels and vortex vein.Retinal digest preparation exhibited that unevenness of vessel diameter,decrease of perithelial cells and increase of endothelial cells in both types of rats.The E/P values were 11.50±3.68in the BN rats and 12.86±3.94 in the SD rats,without significant difference between them (t=9.785,P＞0.05).Conclusions The abnormality of fundus vascular morphology can be better displayed in pigmented diabetic rats than albino rats by FFA in vivo.

Objective To investigate the correlations between plasma levels of carnitine(CT),free fat acid(FFA) and insulin resisitance in children with simple obesity.Methods Fifty-six children diagnosed with simple obesity were enrolled as study group(obesity group),36 healthy children as control group.The concentration of plasma level of insulin was measured by radioimmunoassay(RIA),CT was measured by high performance liquid chromatography(HPLC),FFA and triglyceride(TG) were measured by enzymatic-colorimetric assay.Body mass index(BMI) and waist to hip ratio(WHR) were caculated.Insulin sensitivity index (InSI) and insulin resistance index (InRI) were cacula-ted by homeostasis model assessment of insulin resistance (HOMA-IR).SPSS 13.0 software was used to analyze the data.Results The concentration of CT in plasma was (43.67?12.75) ?mol/L in obesity group,(58.31?21.25) ?mol/L in control group,respectively.There was a significant difference between 2 groups (t=2.566 P
