Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.

The M and NP genes of H5N1 avian influenza virus (A/chicken/Hubei/489/2004) were amplified by RT-PCR from viral RNA,and cloned into pMD 18-T vector respectively.The expression plasmid containing the M gene (pHM6-m) or the NP gene (pHM6-np) was then constructed by inserting the M or NP gene into the pHM6 eukaryote expression vector; the constructed plasmid was then sequenced.32 BALB/c mice (6-week-old) were divided into four groups at random.Three groups of BALB/c mice were inoculated one time the intramuscular route with either 30 μg of plasmid pHM6-m,30 μg of plasmid pHM6-np or the mixture of plasmid pHM6-m (15 μg ) and pHM6-np(15 μg) respectively.A additional group of mice were injected with 100 μ1 PBS as controls.Two weeks later,all mice were challenged with homologous H5N1 avian influenza virus,and observed in the following 12 days.The survival rates of mice in the pHM6-m group,the pHM6-np group and mixed plasmids group were 62.5% ,25.0% and 50.0%,respectively.Results showed that effective protection could be provided by either pHM6-m or pHM6-np,but pHM6-m provided a better protective effect than pHM6-np.

Objective To evaluate the clinical efficacy of interventional occlusion of ventricular septal rupture (VSR) complicating acute myocardial infarction (AMI). Methods Six patients with VSR complicated after AMI underwent transcatheter interventional occlusion in Chinese PLA General Hospital between May 2009 to May 2015 were retrospectively analyzed. Their clinical features, interventional treatment protocols, and occurance of postoperative complications were studied. Results Among the 6 patients, VSR were successfully occluded in 5 patients. One patient failed the operation due to instability of occluder after it was deployed and the occluder was retrieved. The paitents died of heart failure 6 months later. Among the 5 patients with successful closure, 4 patients presented mild residual shunt after occlusion and acute left heart failure occurred in 1 patient after operation. Two patients died during hospital stay after operation. Between them, one patient died 3 hours after operation because of cardiac tamponade and the other patient died of cardiogenic shock after withdrawal from IABP. Three patients were followed up until now and follow up echocardiography showed satisfactory cardiac function without heart failure. Conclusions Transcatheter occlusion was a reliable therapy for patients with ventricular septal rupture complicated in acute myocardial infarction which could improve cardiac function and reduce mortality.

OBJECTIVETo discuss the clinical effect of closed reduction and interlocking intramedullary nailing in the treatment of femoral shaft fracture.

METHODSFrom March 2006 to December 2011,103 patients with femoral shaft fracture were treated by closed reduction and interlocking intramedullary nailing including 76 males and 27 females with an average age of 36 years old ranging from 19 to 55 years old. According to AO classification,there were 64 cases with type A,27 with type B, 12 with type C. Thirteen cases were open fractures including 5 cases with Gustilo type I , 8 with Gustilo type II . The time of bone healing were observed after operation, the knee function recovery was evaluated by HSS scoring standard at 1 year after operation.

RESULTSThe intraoperative complications included femoral neck fracture in 1 case and proximal femoral fracture in 1 case,both of the patients were treated with reconstructive intramedullary interlocking nail and the fractures healed postoperatively. One patient was suffered from common peroneal nerve injury,which were fully recovered at 4 months later after medical treatment. All the patients were followed up from 12 to 28 months (averaged 22 months). All of the fractures were healed well and the average healing time was 3 to 9 months (averaged 5 months). All the hip joints were recovered to normal function. The average HSS was 90.89±5.06 at 1 year after operation.

CONCLUSIONInterlocking intramedullary nailing is the preferred treatment for patients with femoral shaft fracture. Carefully operating and closed reduction can reduce the complications.
