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 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.

Objective:To explore the effect of fortified human milk feeding on growth and complica-tions of infants with extremely and very low birth weight (ELBW/VLBW)during hospital stay by a pro-spective,random and controlled study.Methods:In the study,1 22 ELBW/VLBW infants were enrolled and divided into two groups.The infants fed with human breast milk,combined with human milk fortifi-cation (HMF)during hospital stay were named HMF group (n=62),and those fed exclusively with pre-mature formula were named premature formula feeding group (PF group,n=60 ).The data of the in-fants’growth (the velocity of increase on the weight,length,head circumference and upper arm circum-ference),the time of rebounding to birth weight,the time of needing intravenous nutrition,the time of hospitalizing,the proportion of extrauterine growth retardation (EUGR)during hospital stay,the level of hemoglobin,bone metabolism and incidence of complications were compared between the two groups. Results:Among the 1 22 infants included,(1 )the length increment in HMF group was higher than PF group [(0.89 ±0.23)cm/week vs.(0.79 ±0.34)cm/week,P=0.04];there were no significant differences in the weight gain,head circumference increment and upper arm circumference increment (P>0.05);(2)the age of rebounding to birth weight [(1 0.1 3 ±4.03)d vs.(8.03 ±3.28)d,P=0.002]and the duration of intravenous nutrition [(1 6.77 ±6.63)d vs.(1 4.23 ±4.1 5)d,P=0.01 ] in HMF group were longer than that in PF group,there were no significant differences between the two groups in the hospital stay and age achieved feeding;(3 )there were no significant differences between the two groups in the incidence rate of EUGR during hospital stay (P>0.05);(4)the level of calcium at birth in HMF group was lower than that in PF group [(2.1 9 ±0.22)mmol/L vs.(2.32 ±0.27) mmol/L,P=0.005 ],and the level of alkaline phosphatase (AKP)in HMF group at discharge was higher than in PF group [(363.98 ±1 22.49)mmol/L vs.(299.73 ±1 1 7.39)mmol/L,P=0.004];(5)the incidence of the feeding intolerance (6.5% vs.1 8.3%,P=0.04)and sepsis (4.8% vs. 1 6.7%,P=0.03)in HMF group were less than in PF group,there were no significant differences be-tween the two groups on the morbidity of necrotizing enterocditis,retinopathy of prematurity (ROP),and bronchopulmonary dysplasia (BPD)(P>0.05).Conclusion:HMF for premature infants may ensure the same growth pattern as those fed by premature formula,promote the calcium absorption,decrease the inci-dence of sepsis and feeding intolerance,and does not increase the incidence of necrotizing enterocolitis.

Objective To analyze the clinical features and factors associated with knee osteonecrosis in patients with systemic lnpus erythematosus (SLE).Methods Medical charts of Peking Union Medical College Hospital from 2000 to 2013 were reviewed to identify patients who were diagnosed as SLE with kuee osteonecrosis.Controls were selected and matched to the cases by age and sex.The clinical and laboratory variables were compared between SLE patients who were with and without knee osteonecrosis.Numerical data and categorical data comparisons were analyzed using t-test,x2-test,respectively.Results Sixteen patients developed knee osteonecrosis that constituted 0.37％ of all the 4 301 hospitalized SLE patients during the same period.Fifteen patients were female,who developed knee osteonecrosis with an average age of 36 years (range:17-67 years).The mean duratiou of SLE before the diagnosis of knee osteonecrosis was 64±40 months (range:16-120 months).The interval from onset of symptoms to diagnosis was 0.5 to 24 months.The distal end of femur was involved in all 16 patients,while the proximal tibia necrosis also occurred in 8 patients.The detection rate of knee osteonecrosis by MRI was 100％,while it was only 19％ by plain radiography.The incidence of skin vasculitis,myositis,osteoporosis,hyperlipidemia,hypoalbuminemia and elevated serum immunoglobin G levels were significantly higher in SLE patients with knee osteonecrosis than in controls (P＜0.05).In addition,the use of anti-malarials was significantly lower in SLE patients with knee osteonecrosis than in controls (P＜0.05).Conclusion The knee osteonecrosis in SLE patients is affected by multifactors.The risk factors include skin vasculitis,myositis osteoporosis,hyperlipidemia,hypoalbuminemia and the elevated immunoglobin G level.The use of antimalarial drugs in SLE patients may protect against knee osteonecrosis development.Knee osteonecrosis coull be diagnosed early by MRI.

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.

This paper was aim to determine five phenolic acids, sodium danshensu (SD), protocatechuic aldehyde (PA), rosmarinic acid (RA), lithospermic acid (LA) and salvianolic acid B (SAB), in Guanxinning injection. In the test, Kromasil C18 column (4.6 mm x 250 mm, 5 µm) was adopted, with acetonitrile-3% formic acid solution as the mobile phase for gradient elution. The flow rate was 1 mL · min, the column temperature was 30 °C and the detection wavelength was 280 nm. According to the results of the test, SD, PA, RA, LA and SAB showed good linear relations between peak areas and sample sizes in 0.006 06-4.04 (r = 0.999 3), 0.006 15-4.10 (r = 0.999 4), 0.005 94-3.96 (r = 0.999 3), 0.006 06-4.04(r = 0.999 1) and 0.006 09-4.06 (r = 0.999 2) µg, respectively. The average recoveries (n = 6) were 98.9% (RSD 0.75%), 98.1% (RSD 1.2%), 100% (RSD 0.77%), 98.7% (RSD 1.7%), 102% (RSD 0.68%), respectively. The above 5 components were determined in 13 batches of samples by using the established method.
