Objective To investigate the treatment effect of the proximal humeral internal locking system (PHIL()S) on the elderly patients with displaced proximal humeral fractures.MethodsFrom Feb 2004 to Mar 2007, 36 patients (mean age: 72.2 years) with proximal humeral fractures were treated with PHILOS plate fixation which included 14 cases with 2-part, 17 cases with three-part and 5 cases with four-part fractures according to Neer classification.Operation time,intraoperative blood loss, blood transfusion, perioperative complications and function evaluation of the operated shoulder joint were calculated with 14.5 months follow-up at average.Results The average operation time and blood loss were (61.5± 11.6) min and ( 165.2±91.2) ml, respectively. 1 case with accidents of blood vessel and 1 case with pneumonia were found without neurovascular injuries. All fractures were radiographically healed in an average of 3-5 months.No necrosis of humeral head appeared and 30 (83.3%) cases were excellent or good according to Neer scoring system. Two part fracture and early operation ( within 3 days after operation) might improve the postoperative function of shoulder joint, but the patient's age, gender and ASA score were not statistically with Neer score.Conclusions PHILOS plate fixation is a suitable procedure for displaced proximal humeral fractures via stable fixation and early rehabilitation, especially for elderly patients combined with osteoporosis.

OBJECTIVETo evaluate the effects of alendronate on the structural properties of trabecular bone.
METHODSAlendronate was administered at a daily p.o. dose of 0.5 mg/kg over a 12-week period in hound dogs (n = 8 for both the control and treated group), and the structural indices of the lumbar vertebral (L1 and L2) trabecular bone were assessed directly from 3-D images.
RESULTSTreatment with alendronate increased bone volume fraction by 9.5% and 7.7% in L1 and L2 respectively. Trabecular thickness significantly increased after alendronate treatment, whereas trabecular separation remained constant. The degree of anisotropy for the alendronate-treated group was decreased compared with that of the control group. Bone surface to volume ratio declined significantly in the alendronate-treated group, whereas alendronate induced a higher bone surface density.
CONCLUSIONAlendronate increased the structural properties of canine trabecular bone after short-term treatment at a dose of 0.5 mg x k(-1) x day(-1).

Objective To evaluate the T lymphocyte functions in elderly patients following major orthopedic operation. Methods From May 1998 to Feb 1999, 39 elderly patients (65 95 years old) hospitalized for orthopedic operation were studied. The patients' peripheral blood samples in the experimental group were obtained on days 1, 3, 7 and 14 postoperation, respectively. At the same days, blood samples were taken from 15 elder patients without trauma and operation (65 80 years old) within 6 months as controls. T lymphocyte subpopulations were differentiated by means of quantitative assay with autocounting method of FCM. Results CD3 T cell count was significantly decreased on day 1(54 4?11 3)% and day 14(58 5?12 6)%, compared with controls (63 9?8 3)% ( P

Objective:
To investigate the correlation of early incubator temperature fluctuation on intraventricular hemorrhage (IVH) in very/extremely-low birth weight infants (E/VLBW).
Methods:
From July 2015 to September 2016, 270 patients of hospitalized E/VLBW were included in this study. Temperature changes including incubator temperature and abdominal temperature within 72 hours after admission and routine clinical data were collected,the E/VLBW were divided into IVH group and non-IVH group, as well as the occurrence and grading of IVH. Chi-square test, t test and nonparametric test and logistic regression analysis were used to explore the effect of early incubator temperature fluctuations in E/VLBW on IVH.
Results:
Of the 270 V/ELBW studied, the incidence of IVH was 24.4% (66/270) , severe IVH(grade Ⅲ and Ⅳ) was 5.2% (14/270) . Univariate analysis showed that in addition to common IVH risk factors such as gestational age, body weight, 1/5 min Apgar score, sex, delivery, hyperglycemia, prenatal steroid and mechanical ventilation, fluctuations of body temperature and incubator temperature were relevant for IVH in E/VLBW (
