Journal of Chongqing Medical University 1986;0(04):-
Objective:To investigate peak bone mass(PBM) of female adults in Chongqing area and PBM change of females' lumbar vertebrae with age,bodyweight, height and body mass index(BMI),to provide scientific basis for diagnosis and prevention of osteoporosis. Methods:There were 1435 female adults in Chongqing area randomly selected. The assessment of BMD in spine region was performed by NORLAND XR-46 dual-energy X-ray absorptiometer. BMD of lumbar spine with age-related changes was fitted in the whole healthy women population by eight kinds of regression models. Best model equations of fitting were found and the reference databases of BMD in women were established.Group aged from 20 to 50(n=631)was PBM research group. Results:The PBM of the second,third and total lumbar vertebrae occurred in the group aged from 34 to 35,while that of the forth lumbar vertebrae occurred during 26 to 27 and reduction began at the age of 28. BMD would gradually decrease with the advancing of age when it achieved PBM. R square of cubic regression curve was maximum. The research showed height?body weight and BMI could influence PBM values of lumbar vertebrae. The effect of body weight was the most significant among these influential factors. Conclusions:The PBM level of female adults in Chongqing area was lower than that of other related research results in domestic,and the age of PBM was earlier than that of the others. A cubic regression model was the better model to establish a normal BMD reference curve. Proper nutrition and suitable figure keeping could result in higher PBM value in human life.

5.Ultrasound-assisted neuraxial anesthesia in a patient with previous lumbar laminecto-my and fusion:a case report
Journal of Peking University(Health Sciences) 2016;48(4):747-750
SUMMARY A patient with previous L3 -4 posterior lumbar interbody fusion,pedicle screws instrumen-tation and L3 -4 decompression,was scheduled for left total hip arthroplasty.Two years ago,due to poor landmarks palpation,the patient experienced a failed lumbar puncture after multiple attempts before her-niorrhaphy.His plain radiography showed bilateral partial laminectomy at L3 -4 level,and between L3 and L4,two posterior pedicle screws connected by metal rods on both sides.This time,we used ultra-sound to locate L4 -5 interlaminar space in paramedian sagittal oblique view and identified the spine midline by transverse interlaminar view before puncture.According to this information,L4 -5 puncture point was verified and the combined spinal-epidural anesthesia was performed in a paramedian approach. After withdrawing clear cerebral spinal fluid,15 mg hyperbaric bupivicaine was injected into intrathecal space.An epidural catheter was then inserted into the epidural space.The sensory block level was fixed at T10 to S within 10 minutes.Intraoperatively,the patient received 10 mL 2% (mass fraction)lido-caine through the epidural catheter in total.The surgery was uneventful.No neurologic complication was observed after the surgery.This case report demonstrates that ultRASound imaging can provide useful in-formation for neuraxial needle placement and can be a valuable tool in managing patients with anatomical change around the spine.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2015;29(3):270-274
OBJECTIVE:
To investigate the influence of budesonide on animal model of minimal persistent inflammation (MPI) of allergic rhinitis in rats and to investigate the changes of interleukin-12 (IL-12) in nasal mucosa.
METHOD:
Sixty Sprague-Dawley (SD) rats were randomly divided into four groups: group A (allergic rhinitis group), B (experimental group), C (MPI model group) and D (bland group) respectively, with fifteen animals in each group. Rats from group A,B and C were sensitized intraperitoneally by injection of suspension of ovalbumin (OVA) and aluminum hydroxide in 0.9% physiological saline. Then, repeated local booster sensitization with different concentration of OVA suspension (1% and 0.01%) or physiological saline into the nasal cavity of those rats were performed. For group D, physiological saline was used only. From 36th day, group B were given budesonide treatment for three weeks. A, C and D group were given normal saline nasal spray. Symptoms (sneezing) of rats after antigen challenge were observed and the infiltration of eosinophils (EOS) together with the expression of intercellular adhesion molecule 1 (ICAM-1) and IL-12 in the nasal epithelial cells were also examined.
RESULT:
When challenged with 1% OVA, the sneezing number of rats in group B was increased markedly than that in group D (P < 0.05). However, there was no difference between group B, A and C (P > 0.05). When challenged with 0.01% OVA and given budesonide, the symptom of sneezing almost disappeared in group B just like that in group D and there was no difference between the two groups (P > 0.05). Besides, there was still more EOS infiltrated in the nasal mucosa of rats in group C than that in group D (P < 0.05). There was no expression of ICAM-1 in nasal epithelium of rats in group D, nevertheless, ICAM-1 was found mildly expressed in group C. IL-12 expression was significantly increased compared with group A and group C, and was no significantly difference compared with bland group (P > 0.05).
CONCLUSION
Budesonide significantly inhibited the late reaction of animal model of minimal persistent inflammation (MPI) of allergic rhinitis in rats and increase the expression of IL-12 in MPI model.
