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.

BACKGROUND: It is a key point to revascularize the tissue-engineered bone during the repairing of large bone defect. Fascia flap is commonly used in clinic to accelerate the blood supply of implant.OBJECTIVE: To observe the feasibility of repairing goat tibia defects with tissue-engineered bone and accelerating revascularization with fascia flaps.DESIGN: Randomized and controlled animal experiment SETTING: Department of Traumatic Orthopaedics, Nanfang Hospital,Southern Medical University.MATERIALS: Totally 36 goats with the body mass of 14.5-15.5 kg of either gender were enrolled.METHODS: This experiment was conducted at the Department of Traumatic Orthopaedics, Nanfang Hospital, formerly the First Military Medical University of Chinese PLA from December 1999 and December 2003.Bone and periosteum defects 20 mm long were made and fixed with plate of left tibia in 36 goats. They were randomly divided into four groups: Group A in which the defects were filled with coral hydroxyapatite (CHAP), Group B I CHAP+ bone marrow stroma cells (BMSc); Group C with fascia flaps;Group D with nothing. Next, the bone regeneration and the revasculariza tion were evaluated. Radionuclide bone imaging was done 2, 4, 8 weeks after operation. After X-ray examination, the index of optical density of Xray films and histology of the implants were analyzed at 4, 8, 12 weeks after operation, and the biomechanical characters were studied 12 weeks postoperatively.MAIN OUTCOME MEASURES: Gross observation and X-ray, radionuclide bone imaging, biomechanical and histological observation RESULTS: Totally 36 goats entered the stage of result analysis. ① Gross observation of the repair sample of bone defects of the animals in each group: there was no osteogenesis postoperatively at each time point in the blank control group . In Group B, at week 8 to 12, there was no obvious osteogenesis and callus formation on the surface of the materials. In Group C,At weeks 8 to 12, bone defects were filled gradually, many bone callus processes were seen on the surface of the materials , centralizing and enwrapping the materials. The osteogenetic process in the Group C were superior to that of theGroup B. ②Examination result with -901/SA PET-CT scanners: It was seen by naked eyes that at weeks 2 to 8 in the Group A,the radioactivity concentration at region of interesting (ROI) of the operation side had obvious increasing trend, and similar trend of changing appeared in the Group B and Group C, but the ROI counts and T/NT value in the Group B were both lower than those in the Group C. The decreasing trend in the Group A was lower than that in the Group B. ③) Radiological results: the osteogenesis volume through measuring absorbance in the order from large to small was Group C, Group B, and Group A[At week 12, they were (4.180±0.192), (3.480±0.453), (2.959±0.682)respectively ].④Biomechanical results: there were significant difference of loading and bending stress in the Group C, Group B and Group A [ The loading was (758.333±88.754), (530.214±65.297), (359.667±60.715)N , respectively; and the bending stress was (13.937±2.199), (10.123±1.243),(6.223±0.945)N/mm2, respectively ].⑤)Histological results: Slices at various time points in the blank control group showed no bone tissue. In the other three 3 groups, with the prolongation of time, the osteagenetic range and quality were in the order of Group C, Group B and Group A.CONCLUSION: The fascia flaps can accelerate the revascularization process in the formation of tissue-engineered bone so that the capability of tissue engineered bone to repair the large bone defects may be enhanced.

BACKGROUND: The main aspect of the study in the bone histological engineering is how to maintain and improve theosteogenesis of the osteoblasts in vivo and in vitro. The gene transference may provide a new effective method to deal with theproblem.OBJECTIVE: To discuss the effect of the reverse transcription virus mediated human bone morphogenetic protein7(hBMP-7) gene transfection on the proliferation and osteogenetic differentiation of the bone marrow mesenehymal stemcells (BMSCs) of the rabbits.DESIGN:Cells taken as the study object, grouping control, repeat observation andmeasurement.SETTING: Traumatological and othopaedic lab of a medical university hospital.PARTICIPANTS: The study wascompleted in the Traumatological and Othopaedic Lab in the Affiliated Nanfang Hospital of the Southern Medical University from July 2001 to July 2003. Four New Zealand rabbits,whose weights varied from 1.0 to 1.5 kg, were provided without sexlimit by the Animal Experiment Center of the First Military Medical University of Chinese PLA.METHODS:The reverse transcription virus carriersof the hBMP-7 were constructed,and then the BMSCs were transfected by the virus containing target genes. The expression of the hBMP-7 protein was detected with the immunohistochemical method. The cell proliferation, cycle and ALP synthesis were respectively detected with the MTT method,flow cytometer and NPP method.MAIN OUTCOME MEASURES: Primary results: ① the detection results of the cell proliferation. ② the detection results of the ALP.Secondary results: ① the expression of the hBMP-7 protein in the transfected BMSCs. ② the detection results of the cell cycle.RESULTS: After the BMP-7 gene transfection, there was hBMP-7 positive expression in the BMSCs of the rabbits,using the immunohistochemical detection. There was no significant change in the BMSCs proliferation of the rabbits after the hBMP-7 gene transfection ( P ＞ 0.05). Compared with the ALP synthesis of the transfected BMSCs(294. 592 ± 86. 567) nkat/L, there was significant difference in the ALP synthesis of the empty carrier transfected BMSCs(155. 231 ±86.567) nkat/L and the un-transfected BMSCs (160. 866 ±91. 585)nkat/L( F =5. 660, P ＜ 0. 05).CONCLUSION: After the BMP-7 gene transfection, the BMSCs can synthesize and express the extragenous BMP-7. The hBMP gene transfection can promote the differentiation of the BMSCs cultured in vitro into the osteoblasts and can be used as the seed cells in the construction of the histological en gineering bone tissues and in further application.

Objective: To explore the relationship between serum level of high-sensitivity cardiac troponin T (hs-cTnT) and atrial ifbrillation (AF) occurrence in patients with stable coronary artery disease (CAD).
Methods: A total of 1011 patients with stable CAD treated in our hospital from 2013-01 to 2015-09 were retrospectively studied. According to quartiles of hs-cTnT, the patients were divided into 4 groups: Group① the patients with hs-cTnT≤7ng/L, n=283, Group② hs-cTnT 7-10ng/L,n=238, Group③ hs-cTnT 10-15ng/L,n=272 and Group④ hs-cTnT>15ng/L,n=218. The relationship between hs-cTnT level and AF occurrence rate was studied; the risk factors for AF occurrence were explored by multi stepwise Logistic regression analysis.
Results: There were 127/1011 (12.6%) patients combining AF and 884 (87.4%) with simple type stable CAD. AF patients had the higher serum level of hs-cTnT than non-AF patients 17.0 (12.0, 25.0) ng/L vs 10.0 (7.0, 13.0) ng/L,P<0.01. With baseline hs-cTnT level increasing, AF occurrence rates were elevated from group① to Group④ as 4.6% (13/283), 4.6% (11/238), 11.0% (30/272) and 33.5% (73/218), Ptrend<0.05. Multi stepwise Logistic regression analysis revealed that with adjusted common risk factors of age and gender, the risk for stable CAD patients suffering from AF in Group④ was 5.324 times higher than group① (95% CI 2.285-12.405,P<0.01).
Conclusion: Increased serum level of hs-cTnT was closely related to AF occurrence in patients with stable CAD.

Objective To investigate the efficacy of tamsulosin in the distal ureter calculi expelling after ureteroscopic lithotripsy. Methods A total of 120 patients with distal ureteral calculi were enrolled and randomly divided into the observation group and the control group with 60 patients in each group. Patients in the observation group received tamsulosin and traditional treatment ( including liquid impact therapy,anti-inflammatory and analgesia) ,while patients in the control group received placebo and traditional treatment after operation. The number of colic episodes,lower urinary tract symptoms,analgesic dosage,and time of calculus removing were recorded and all the data were statistically analysed through software SPSS 13. 0. Results There was no singinificant difference between the two groups in the rate of calculus removing (P>0. 05), but it took less time in the observation group (P<0. 05). In addition, it was of less low urinary tract symptoms, low-er rate of analgesic usage and colic episodes in the observation group with statistically significant differences compared with the control group (P<0. 05). Conclusion The application of tamsulosin after ureteroscopic lithotripsy can reduce the rate of colic episodes and analgesic dosage and time of calculus removing.
