Objective To evaluate a minimally invasive procedure for intertrochanteric fracture treatment in elderly patients. Methods Total 46 elderly patients with intertrochanteric fracture were treated with a minimally invasive procedure from September 2008 to February 2010. The fractures were fixed with multiple K-wires combined with skeletal traction through supracondyle of femur. All procedures were undertaken under local anesthesia. Results All the patients were followed up for 8.8-months in average, and 42 patients recovered with independent walking, and the good rates was 91.3%, without severe complications in this group. Conclusions Minimally invasive procedure including fixation with multiple K-wires combined with traction through femoral supracondyle, is a safe and effective treatment for intertrochanteric fracture in elderly patients, avoiding high risks of intra-and post-operative complications.

BACKGROUND:Knowledge of retropedtoneal space communications might influence catheter placement,and understanding the normal anatomy of the retroperitoneal space is a prerequisite for predicting the distribution of inflammation or other fluid collections in this region. Until recent years,the media/ attachment of the posterior renal fascia remained controversial. The multiple detector spiral CT can show the abdominal anatomic details. So,using the multiple-detector spiral CT to study the anatomy of posterior renal fascia has clinical significance. OBJECTIVE:To describe the medial attachment of the posterior renal fascia by using multiple-detector spiral CT. DESIGN,TIME AND SETTING:A retrospective case analysis was performed at Department of Radiology,Affiliated Hospital of Weifang Medical College between June 2003 and November 2007. PARTICIPANTS:A total of 52 patients with retropedtoneal inflammatory diseases were retrospectively reviewed through analysis of their CT data. METHODS:Toshiba Akuilion 16-detector spiral CT was employed for scanning. Of the 52 patients,15 were proved by clinical and laboratory findings and 37 were proved by surgery and pathology. Among the 52 patients,17 suffered from appendicitis,1 from ureteritis,2 from abscesses in the perirenal space,3 from abscesses in the posterior pararenal space,and 29 from pancreatltis. MAIN OUTCOME MEASURES:Medial attachment of the bilateral posterior renal fascia. RESULTS:At the level of the upper pole of kidney,the posterior renal fascia fused with the fascia of the ipsilateral quadratus lumborum muscle. Forty-six patients manifested the attachment site of the left posterior renal fascia transforming from the quadratus lumborum muscle fasciae to the psoas major muscle fascia at the level of the lower pole of kidney or the infrarenal space. Fifty patients showed the attachment site of the right posterior renal fascia transforming from the quadratus lumborum muscle fascia to the psoas major muscle fascia at the level of the lower pole of kidney or the infrarenal space. CONCLUSION:The posterior renal fascia attachment site is not the same all the time. At different levels,the attachment site of the posterior renal fascia is distinct.

Objective To investigate the effects of C-terminal fragment of parathyroid hormonerelated protein (PTHrP107-139) on bone mineral density (BMD), bone histomorphometry and biomechanical properties in ovariectomized (OVX) rats and its effect on bone metabolism is also explored. Methods Forty 4-month old female Wistar rats in which 30 were ovariectomized and then divided into 3 groups: the placebo, the PTHrPC and the CT groups, the other 10 rats were Sham-operated as the control group (Sham). Five weeks later, the rats of PTHrPC and CT groups were subcutaneously injected with PTHrP107-139 (40 μg/kg) and Salmon Calcitonin (15 U/kg) respectively once every other day. The rats of the placebo and sham groups were injected with 0.2 ml saline once every other day. After treatment of 12 weeks, all rats were sacrificed and all samples were collected and analyzed. Results ① Compared with the placebo, the BMD and bone strength of PTHrPC and CT groups were significantly increased (P<0.05). ② Histomorphometry revealed that the tetracycline labeled bone surfaces, osteoid surfaces, mineral apposition rate and bone resorption rate were remarkably decreased in PTHrPC, and CT groups comparing with those of the placebo group. Conclusion Cter-minal PTHrP107-139 is effective in increasing the BMD, bone strength and quality when administered intermittently to ovariectomy-induced osteoporotic rats. Its increasing in bone quality may relate to reducing bone turnover and inhibiting resorption.

OBJECTIVE The head of malleus (HOM) was regarded as the landmark for the middle cranial fossa approach,and its relationship with internal auditory meatus(IAM) was measured. The purpose of this study was to find a safe method to locate IAM. METHODS Twelve heads of adult cadaver fixed with 10 % formaldehyde (23 sides) were microsurgically dissected from the middle cranial fossa approach. The foramen spinosum,Ferrein's foramen,greater petrosal nerve,lesser petrosal nerve,facial nerve,HOM,arcuate eminence,superior petrosal sinus,semicircular canal,and IAM were exposed. First,blue lines method was used to locate IAM. Second,HOM as the landmark was used to locate IAM. RESULTS The angles between the SSC and the longitude axis of IAM are 58.52??4.84?。 A perpendicular line (AB) was drew from the center of HOM to the longitude axis of the temporal bone (the longitude axis of the superior petrosal sinus),line BC was drew from the anterior 30?(28.93?? 6.07?) to the line AB. On the line BC,fundus of IAM can be located (6.69?1.10) mm medial to HOM,the center of the internal acoustic pore can be located (20.1?1.48)mm medial to HOM. CONCLUSION In the middle cranial fossa surgery,HOM can be used to locate IAM and its surroundings structures when traditional landmarks are unrecognized.

Medication has become the first-line option for the management of lower urinary tract symptoms induced by benign prostatic hyperplasia (LUTS/BPH) for its advantages in controlling the symptoms, inhibiting BPH progression, and reducing serious complications and surgical risks. Recent years have witnessed remarkable achievement in the studies of phosphodiesterase type 5 inhibitors (PDE5-Is) in the treatment of LUTS/BPH. PDE5-Is can effectively alleviate LUTS/BPH, with even better efficacy when combined with al-ARAs.

Objective To investigate the therapeutic effects of human parathyroid hormone related protein (PTHrP1-34) on osteoporosis of ovariectomized osteoporotic rats. Methods Sixty 4-month-old female Wislar rats were involved in this study and 40 of them were ovariectomized and another 20 received sham operation. After 6 weeks of ovariectomy the osteoporosis model was confirmed by examing 10 ovariectomized and sham-operated rats. The 30 osteoporotic rats were randomly divided into 3 treatment groups, i.e. PTHrP, estradiol and placebo. Human 40 ?g/kg PTHrP1-34 was subcutaneously injected once daily to PTHrP group and the estradiol group was injected with 40 ?g/kg estradiol benzoate once every 3 days.The placebo and shamoperated rats were given 0.2 ml saline every 3 days. The bone mineral density (BMD), bone histomorphology, the bone weight of dry and ash and serum Ca,P,alkaline phosphatase (ALP) were measured after 3 months' therapy. Results After 6 weeks of ovariectomy, the lumbar BMD of ovariectomized rats were significantly declined compared with those of the sham-operated rats. After 12 weeks treatment the femoral and lumbar BMD and the rate of bone weight of dry and ash in the PTHrP group were increased obviously compared with those of placebo groups.There was no significant difference between PTHrP group and estradiol group, in PTHrP group the percent age of trabecular area,trabecular width,osteoblast surface and mineral apposition rate were obviously higher than those in placebo group.Conclusion Treatment with 40 ?g/kg dose of hPTHrP1-34 administered once daily is effective in treating ovariectomy-induced osteoporosis.
