OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.
METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.
RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).
CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

Objective To study early changes in biochemical markers of bone turnover for prodicting the bone mineral density(BMD) response to alendronate therapy in Chinese men with osteoporosis. Methods Seventy-eight men aged 60 to 82 years with osteoporosis [mean age (69.8 ±11.8) years]were treated with alendronate sodium 70 mg/week for 12 months. Serum bone gla-protein (BGP) and serum pyridinoline-eross-linked earboxyterminal telopeptide of type I collagen (ICTP) level were measured by chemiluminescence (equipment is Roche E170). Serum BGP, ICTP and BSALP levels were measured before and 3 months and 12 months after treatment. BMD in lumbar spine and femoral neck were measured with dual energy X-ray absorptiometry (GE PRODIGY Inc. ) at L1-4 and at the left hip(total hip,trochanter,Ward's area and femoral neck)before and 12 months after treatment. Results After 3-months and 12-months treatment, the percent reductions of serum ICTP levels were 45.8% and 51.6%, serum BGP level 32.0% and 37.5%, serum BSALP level 35. 3% and 39.9% ,respectively. After 12-months treatment, the percent increase of lumbar BMD was 11.8%, femoral neck BMD 11.4 %. The percent reductions of serum ICTP level at months 3 and 12 after treatment were positively correlated to the percent increase of lumbar BMD (r=0.28, 0.295,P <0.05 and P<0.01)and of fermoral neck BMD at 12 months after treatment(r=0.262, 0.333, P<0.05 and P<0.01)respectively. The percent reductions of serum BGP level at months 3 and 12 after treatment were positively correlated to the percent increase of lumbar BMD (r=0. 322, 0.401,all P<0.01) and of fermoral neck BMD at 12 months after treatment (r=0.277,0.284, all P<0.05)respectively. The percent reductions of serum BSALP level at months 3 and 12 after treatment were positively correlated to the percent increase of lumbar BMD (r=0.133,0.231,all P<0.05) and of fermoral neck BMD at 12 months after treatment(r=0.248, 0.317, all P<0.01)respectively.Conclusions Early changes in biochemical markers of bone turnover rates can predict BMD response to alendronate in Chinese men with osteoporosis.
8.Perioperative goal-directed fluid therapy: grand progress and controversy.
Chinese Journal of Gastrointestinal Surgery 2012;15(6):540-543
Fluid therapy is one of the most controversial topics in perioperative management. Current perioperative fluid therapy is largely based on concepts developed restricted and liberal perioperative fluid administration in the late 1950s and 1960s. However, there are increasing reports of perioperative excessive intravascular volume leading to increased postoperative morbidity and mortality. The concept of individualized goal-directed therapy in surgical patients seems to be an important component for optimization of perioperative fluid management in high-risk surgical patients.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.
METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.
RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).
CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

The technique introduced in this paper is applied in the endocardial catheter operation, which describes the 3D heart model reconstruction before the operation for the endocardial navigation. After a series of CT images of the thorax are processed, an accurate 3D endocardial model can be reconstructed. At first, the series of 2D CT images are preprocessed for denoising and the enhancement,then they are constructed as the volume data. After the region growing segmentation in the 3D volume data according to the grey value of the voxel in the heart cavity, the heart surface rendering is got and the 3D model of endocardial cavity is reconstructed.
