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.

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 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.
