OBJECTIVETo investigate the clinical effect of bridging fixation with locking plate for the Seinsheimer type V subtrochanteric femoral fracture.

METHODSFrom March 2009 to September 2014,18 cases of Seinsheimer type V subtrochanteric femoral fracture were treated by open reduction and bridging fixation with locking plate through proximal and distal approach including 16 males and 2 females with an average age of 41 years old ranging from 22 to 67 years old. Among them, 12 cases caused by traffic accident, 5 cases by falling, 1 case by heavy aboving. All cases were fresh and closed fractures. Time between injury and operation was from 4 to 9 days with an average of 6.2 days. Of them, 11 cases were fixed with reverse LISS and the other 7 cases were fixed with anatomical locking plates of proximal femur.

RESULTSThe mean time of operation was 110 min (ranged from 90 to 155 min). The mean blood loss during operation was 425 ml (ranged from 350 to 650 ml) and 16 cases got blood transfusion which was meanly 300 ml. The mean hospital time was 14 days (ranged from 12 to 18 days). The mean duration of followed up was 11.8 months (ranged from 8 to 22 months). The mean time of bone union was 6.6 months (ranged from 5 to 8 months). There was not any complication such as infection, implant failure, hip varus, external rotation deformity of low limb or fat embolism. The Sanders hip scores were 53.22 ± 6.48, the result was excellent in 12 cases and good in 6 cases at the last follow-up.

CONCLUSIONUnder the principle of biological osteosynthesis, treatment of Seinsheimer type V subtrochanteric femoral fracture with bridging locking plate fixation has such advantages as high mechanism, less interference of blood supply, stable fixation and little complication. It is a safe and idea way for the treatment of the Seinsheimer type V subtrochanteric femoral fracture.

OBJECTIVETo emphasize early differential diagnosis from patients with hyperphenylalaninemia (HPA) and to evaluate the treatment and long-term outcome of patients with tetrahydrobiopterin synthase (BH4) deficiency in Northern Chinese population.

METHODSFrom 1992 to 2005, a total of 618 patients with HPA were diagnosed and/or cared for in our outpatient clinic. Urinary pterin analysis, detection of dihydropteridine reductase (DHPR) activity in blood, and then BH4 loading tests were carried out to differentiate BH4 deficiency in these patients from classical phenylketonuria. BH4 deficient patients were treated with BH4, levodopa and 5-hydroxytryptophane (5-HTP) immediately while the diagnosis was done to disease. Patientso blood phenylalanine levels, psychomotor and intelligence development were followed up.

RESULTSA total of 38 cases were diagnosed as BH4 deficiency, all of them were revealed as 6-pyruvoyl-tetrahydropterin synthase (PTPS) deficiency from the extremely decreased urine biopterin, normal DHPR activities and drop down of blood phenylalanine level to normal range within 4 to 8 hours after BH4 loading. The most common manifestations were progressively psychomotor and mental retardation to patients even after taking early dietary treatment. The patients were diagnosed and treated with drugs at the ages of 2.1 months to 13 years. With 4 patients died of pneumonia, 7 patients refused to treatment, only 27 patients were under treatment and followed up. The average full scale development or intelligence quotient (DQ/IQ) of patients who were treated within and after 6 months were 86+/- 10 or 66+/- 7 respectively. Development was not even in different aspects. A significant negative correlation was observed between the level of the DQ and the age of treatment commenced (r was -0.714, P< 0.01). Eleven patients experienced the extrapyramidal movement disorders, 3 of them combined with epilepsy. The extrapyramidal disorders were controlled by administration of levodopa.

CONCLUSIONThe differential diagnosis for BH4 deficiency should be carried out in all patients with HPA. PTPS deficiency is the most common form of BH4 deficiency in Northern Chinese population. The long-term outcome of these patients benefits from diagnosis and treatment with BH4, levodopa and 5-HTP as early as possible.

OBJECTIVETo compare the effects of close reduction combined with minimally invasive percutaneous plate osteosynthesis for distal fracture of tibial shaft.

METHODSFrom March 2009 to May 2013, there were 124 patients (89 males and 35 females, 30 of them were injured in a traffic accident and 94 were falling down in daily life, the ages ranging from 21 to 81 years old) who suffered from distal fracture of tibial shaft. Sixty-six patients (48 males and 18 females, 45 cases of type A, 12 cases of type B and 9 cases of type C) were treated with close manipulative reduction combined with minimally invasive percutaneous plate fixation. After close reduction, a minimal incision was made and a anatomic plate was inserted just along the medial tibia periostea, and then the fracture was fixed without fracture exposure. The other 58 patients (41 males and 17 females, 41 cases of type A, 10 cases of type B and 7 cases of type C) were treated with conventional open reduction and internal fixation. Length of the incision, operating time, early postoperative pain (recorded using the Visual Analog Scale score) and the outcome results (recorded using the evaluation standard of Johner-Wruhs) were compared.

RESULTSThe length of incision was meanly (7.34 ± 1.42) cm in MIPPO group and (21.82 ± 2.35) cm in ORIF group; operation time was (44.48 ± 10.00) min in MIPPO group and (59.42 ± 11.84) min in ORIF group. The postoperative radiographs verified good position of all screws and satisfactory bone fracture reduction in both groups. All the patients were followed up, and the duration ranged from 10 to 24 months (mean 15.2 months) in both groups. In MIPPO group,only one patient had delayed union and got union after Chinese herb therapy. The other 65 patients got bony union during 15 to 20 weeks. While in ORIF group, 3 patients suffered from nonunion and received reoperation with bone grafting, and 4 patients got bone infection.

CONCLUSIONTreatment of distal fracture of tibial shaft, combined with close reduction and MIPPO technique, has the advantages such as less invasion, less damage of blood supply, simplified procedure of operation and higher union rate, which is an ideal methods and is accordant to the biological demand.

BACKGROUNDOff-label application of drug-eluting stents (DES) during percutaneous coronary intervention (PCI) was not uncommon in daily practice, however DES in treating Chinese patients with complex lesion subset was under-investigated. The primary objective of the FIREMAN registry was to evaluate the long term efficacy and safety of the Firebird sirolimus-eluting stent (SES) in treating patients with complex coronary lesions. Here we report the mid-term of one-year clinical outcomes and eight-month angiographic follow-up results of FIREMAN registry.

METHODSThe FIREMAN registry was a prospective multi-center registry, which included 1029 consecutive patients undergoing PCI with Firebird SES implantation between September 2006 and July 2007 in 45 centers in China. The clinical follow-up was designed to be performed at 1, 6, 12, 18, 24, 30 and 36 months post index procedure, and non-mandatory angiographic follow-up at 8 months was planned. One hundred percent site monitoring was conducted.

RESULTSLong lesions (59.2%), multi-vessel disease (50.4%), and small vessel disease (31.6%) were mostly found in angiography. Major adverse cardiac events (MACE) occurred in 51 (5.1%) patients at 1 year clinical follow-up, including cardiac mortality in 6 (0.6%), non-fatal myocardial infarction in 11 (1.1%), and target lesion revascularization in 36 (3.5%) of the patients. Definite and probable stent thrombosis (ST) by Academic Research Consortium (ARC) definition occurred in 12 (1.36%) patients at one-year clinical follow-up. The 8-month binary restenosis rate was 5.7% in-segment and 4.3% in-stent, respectively. Late lumen loss was (0.21 ± 0.40) mm in-segment and (0.23 ± 0.36) mm in-stent, respectively. Furthermore, Cox regression analysis revealed that diabetes, small vessel diameter, and chronic total occlusion were independent predictors of ST.

CONCLUSIONSThe results showed that the Firebird SES was effective and safe in treating Chinese patients with complex coronary lesions and occurrence of ST rate at one-year clinical follow-up was acceptable, however further long-term follow-up was still necessary. (NCT00552656)
