OBJECTIVETo study the applied value of double joystick technique in reduction-internal fixation for femoral shaft fracture in adults.

METHODSThirty-four patients (24 males and 10 females) with femoral shaft fractures were treated with reduction assisted by double joystick technique and internal fixation with interlocking intramedullary nail from September 2010 to June 2013. The average age of the patients was 41 years old, ranged from 17 to 65 years old. The duration of the disease course ranged from 3 to 7 days, with a mean of 5 days. The fractures belonged to AO types 32A (5 cases), 32B (20 cases) and 32C (9 cases) and located in left femur for 18 patients and right femur for 16 patients. The patients were followed up, and fracture healing and complications were observed. The curative effect were evaluated according to Thorsen femur fracture evaluation standard.

RESULTSThe operative time ranged from 40 to 110 min (mean 75 min) and intraoperative blood loss ranged from 200 to 300 ml (mean 250 ml). All the patients obtained a good fracture reduction and were followed up for 12 to 24 months (mean 18 months) after the surgery. All the fractures united between 4 and 8 months with a mean of 5 months. No complications such as breakage of nail, infection, osteofascial compartment syndrome, refracture and fracture malunion were found. According to Thorsen femur fracture evaluation standard, 30 patients obtained an excellent result, 3 good and 1 fair.

CONCLUSIONIn surgery of reduction-internal fixation for femoral shaft fracture in adults, the use of double joystick technique obtains good reduction result, short operative time, less injury, high healing rate of bone fractures, less complications and good limbs function, so it is worthy of popularizing in clinic.

Objective To learn about electrolytes imbalance and water intoxication in children treated with high-dose cyclophosphamide(HD-CTX)as well as the renal function and the relative clinical symptoms,and study the mechanisms of hyponatremia.Methods Patients' clinical manifestations during and after HD-CTX therapy were summarized.Serum electrolytes and creatinine(Cr)were detected before and 6 or 8 hours after therapy with HD-CTX,antidiuretic hormone(ADH) in some patients were measured.Results Of 108 therapeutic cases 24 accompanied with vomits and 22 with a decreased urine output,in which 4 developed eyelid or ankle edema.Seven cases had neural-sarcous symptoms and 5 cases had abdominal pain or diarrhea.Serum sodium decreased significantly after HD-CTX[(139.12?3.30) mmol/L vs(134.06?8.23) mmol/L] in whom rechecked after 6 h,(141.77?3.59) mmol/L vs(133.26?6.41) mmol/L in those rechecked after 8 h(Pa0.05].Serum Cr increased 8 h after therapy[(29.95?13.61) ?mol/L vs(43.33 ? 17.25) ?mol/L P

Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

Objective To investigate the MR features of pituitary abscess.Methods The MR features of 14 cases of pituitary abscess proved by surgical pathology and clinical treatments were analyzed retrospectively.Results Pre-contrast MR showed hypointense heterogeneous intensity on T_1 WI in 12 cases and iso-hyperintense on T_1 WI in 2 cases,hyperintense on T_2 WI in all cases.Post-gadolinium MR showed the ring-like enhancement around the uneven edge of abscess and the surrounding enhanced meninges connecting to the focus.The normal pituitary could not be identified in all 14 cases.The MR specific findings include the fluid-fluid level,nodule on the edge and the enhanced patchy shadow.Conclusions The pituitary abscess has specific findings on MR examination,which can be used to combine with clinical symptoms to achieve the diagnosis before operation,so that the cases could be treated with antibiotic without operation.

OBJECTIVETo investigate the expression of uncoupling protein (UCP)-2, 3 mRNA in skeletal muscle of the scalded rats after escharectomy at different post scalding stages.

METHODSOne hundred and twenty Wistar rats were employed in the study, in which 8 served as normal control (C) and 112 were subjected to 30% TBSA 3rd degree scalding and then again, divided into 4 groups. The rats in A group were sacrificed on 8th, 24th, 96th, 120th and 168th post scalding hours (PSHs) without escharectomy. The rats in B group underwent escharectomy at 8 PSH, and those in C group underwent escharectomy at 24 PSH. All the rats in both groups were sacrificed on 96, 120 and 168 PSHs after escharectomy, Escharectomy was performed at 96 PSH in rats of D group, and they were sacrificed on 120 and 168 PSHs after escharectomy. The serum levels of leptin and TNFalpha, and the expression level of UCP2 mRNA were determined at all time points in all groups of rats.

RESULTS(1) The serum levels of leptin in A group were obviously lower than that in C group (P < 0.01) during 24 approximately 168 PSHs, while those in B, C and D groups were much higher than those in A group (P < 0.01) during 24 approximately 168 PSH. (2) The serum TNFalpha levels in A group at all time points were higher than that in control group, while that in B group at all time points were lower than that in A group (P < 0.05 or 0.01), and that in C group at 168 PSH was lower than that in A group (P < 0.05). (3) The UCP2 mRNA expression in skeletal muscle in A group was increased evidently since 8 PSH (P < 0.01), peaking at 24 PSH and lowering thereafter, while that in B and C groups at 168PSH was significantly lower than that in A group at the same time points (0.32 and 0.35 vs 0.71, P < 0.05). The trend of the change in UCP3 mRNA expression in skeletal muscle was similar to that of UCP2.

CONCLUSIONThe postburn up-regulation of UCP mRNA expression might play important roles in the increase of metabolic rate. Escharectomy during shock stage could lower down the expression of UCP2 and UCP3 mRNA expression, and it could be beneficial by lowering metabolic rate.

Prevention and treatment of infection in burn patients involve a wide range of issues. This present article is to introduce only briefly clinical experience focusing on this problem. Among them, satisfactory timely prevention and treatment of burn shock is imperative because it exerts tremendous impact on homeostasis, including especially deterioration of immune functions. Early gastro-intestinal feeding is known to help restore gastro-intestinal circulation after shock, and it is an important avenue to give important nutritional elements like glutamine. It is also very important to excise devitalized tissue, followed by total coverage of all open wounds as early as possible, so that nidus of infection is removed. Rational use of antibiotic, immunological modulation and other measured were also important contributory factors in successfully preventing and treating infection in patients with major burns.

OBJECTIVETo observe the ultracytochemical localization of H(+)-adenosine triphosphatase (H(+)-ATPase) in the cell organelles.

METHODSThe localization of H(+)-ATPase in the cell organelles was observed in the hepatocytes and renal cells of Wistar rats using routine ultracytochemical methods.

RESULTSH(+)-ATPase activities were observed on the lysosomal membrane and nuclear envelope of the hepatocytes and proximal tubule epithelial cells of the nephron in Wistar rats.

CONCLUSIONThis finding supports the hypothesis that H(+)-ATPase (V-ATPase) is present on the plasma membrane and in the endomembrane system.
