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.

Objective To explore effect of increasing cerebrospinal fluid (CSF) leptin level by administration from the foramen magnum to the cerebellum medulla oblongata pool in osteoporosis in rabbit model established by ovariectomy (OVX) and methylprednisolones.Methods According to certain inclusion and exclusion criteria,30 adult rabbits which were healthy 5-month-old female New Zealand white rabbits with the same batch and weight were divided into 5 groups (n=6) with random number table,including control group,normal saline group,Low dose group,middle dose group and high dose group.The animal model of osteoporosis (OP) was established 8 weeks after ovariectomy (bilateral ovarian resection) and intramuscular injection of methylprednisolone daily for 8 consecutive weeks in all groups.The control group were only simulated puncture and didn't inject any drugs or normal saline,the normal saline group were intracerebroventricular (ICV) injection with NS and Low,Middle and High dose group injected with low,middle and high dose of leptin respectively at 0,3,7 days after OVX.Before (0 week) and 4,8 weeks after the operation,the measure of dual energy X-ray absorptiometry was done on all the rabbits femur and bone mineral density (BMD) was delivered.Before (0 week) and 4,8 weeks after the first administration,leptin in cerebrospinal fluid (CSF) and serum growth hormone (GH),insulin growth factor 1 (IGF-1) and osteocalcin (OT/BGP) were tested with Enzyme linked immunosorbent assay and serum calcium,phosphorus and alkaline phosphatase (ALP) with automatic biochemical analyzer (ACA).The rabbits were sacrificed and the thalamus and femoral neck were harvested to test the expression of leptin receptor (LEPR) in thalamus and bone morphogenetic protein-2 (BMP-2) and type Ⅰ collagen (Col Ⅰ) at 8 weeks after the first administration.Results Compared with the control group and NS group,the cerebrospinal fluid (CSF) leptin concentration of leptin administration groups kept in a higher level significantly at 4 and 8 weeks after leptin administration,it was positively correlated with the concentration of administration.After administration 4 and 8 weeks,the bone mineral density (BMD) of leptin administration groups were not significantly lower than that of non-administration groups,and the high dose group was unchanged.The serum osteocalcin/bone glad protein (OT/BGP) concentration of leptin administration groups decreased more significantly compared with the non-administration groups at 4 weeks after leptin administration;and it rebounded more significantly than the non-administration groups and low dose group rebounded more significantly than other non-administration groups at 8 weeks.The concentration of serum growth hormone (GH) of 5 groups showed a downward trend at 4 and 8 weeks,the serum GH concentration of leptin administration groups decreased more significantly than the non-administration groups.The concentration of serum insulin-like growth IGF-1 of 5 groups were decreased significantly at 4 weeks,and the serum IGF-1 concentration of control and low dose groups were significantly higher than other 3 groups at 8weeks.Compared with the non-administration groups,the concentration of serum Calcium of leptin administration groups were increased more obvious,and it was positively correlated with the concentration of administration.Serum phosphorus of 5 groups were decreased at 4 weeks and elevated at 8 weeks;there was no difference among the groups.Serum ALP showed a continuous downward trend,and the middle dose group decreased significantly compared with other groups at 4 and 8 weeks.RTPCR results showed that the BMP-2 and Col Ⅰ mRNA expression increased and positively correlated with leptin administration concentration at 8weeks.Conclusion The increase of cerebrospinal fluid leptin level can promote the bone metabolism,reduce bone loss and precaution the occurrence of osteoporosis in rabbit model caused by OVX and methylprednisolone,and it was positively correlated with the concentration of administration.That provides a new method for the prevention and treatment of osteoporosis in rabbit model.

Objective To investigate the enhanced osteogenesis during bone fracture healing after intracerebroven-tricular (ICV) leptin injection, using rabbit model with created segmental bone defect in right tibial. Method Segmental critical-sized defects were created at the right tibial bone of skeletally mature New Zealand white rabbits. In experiment group (leptin group), recombinant rabbit leptin was injected into cerebellomedullary cistern through foramen magnum. While in control group, normal saline was injected in the same way. Bone Mineral Density (BMD) was evaluated by qCT at 1st, 3rd, 7th, 14th and the 21st days. At the 21st days, all rabbits were euthanized to collect the right tibia for histomorphology, to ex-amine the BMP-2 expression in the bone callus by Fluorescence in situ hybridization (FISH). Result In the leptin group, body weight declined more obviously than control group then it start to arise at the 14th day;qCT showed significant higher BMD in leptin group than in control group at the 7th day;FISH showed a higher BMP-2 expression in leptin group than in control group. Conclusion Cerebellomedullary leptin injection through foramen magnum could accelerate limb fracture healing in rabbit model with right tibial bone defection.
