After the necessity of research on bio-entities was pointed out, the advances and status quo in research on the relation between bio-entities were analyzed with concrete ideas and project put forward for the research on bio-entities using scientometric methods according to thecitationrelation in bio-entities similar to that in litera-ture.This kind of research will promote and perfect the research on scientometric theory and practice, and open a new visual angle for the research on knowledge management .

Objective To investigate the safety and medium-and long-term effects of endovascular stenting,axilloaxillary bypass (AAB),carotid-subclavian bypass (CSB) in patients of subclavian arterial occlusion.Method From 2001 to 2013,311 consecutive patients with subclavian arteriosclerosis obliterans were treated with endovascular stenting (n =191),axilloaxillary bypass (n =96) or carotidsubclavian bypass(n =32).We collected patients' medical data,calculated patency of the graft or stent with life-table method and compared patency between three approaches with Log-rank.Results The incidence of perioperative complications was 4.1％ in the stenting group vs.11.5％ in AAB group vs.18.7％ in CSB group.There was significant statistical differences between the stenting group and bypass group about the incidence of perioperative complications.The primary patency rates at 1,3 and 5 years were 90.3％,84％,81.6％ in stenting group vs.95.3％,92.6％,88.9％ for AAB group vs.100％,96.4％,96.4％ for CSB group.There was significant statistical differences between the stenting group and bypass group about the primary patency rates.Conclusions Both endovascular stenting and extrathoracic surgical bypass are safe and effective treatments for subclavian arteriosclerosis obliterans.However,effect of extrathoracic surgical bypass is more durable in the medium-and long-term.

The classical prescriptions in Typhoid Miscellaneous Disease can be used to alleviate the common hung cancer symptoms and complications like fever, cough, pain and pleural effusion effectively. The preoperative medication can improve lung cancer patients’ surgical tolerance, and postoperative medication can facilitate patients’ postoperative rehabilitation. And if combined with chemotherapy, they cound reduce toxicity and enhance efficiency, enhance the patients’ immunity and improve their life quality. Research shows that classical prescriptions can improve the immunity of lung cancer model mice, facilitate apoptosis of tumor cell and control its migration. This paper sumed up the clinical and experimental research of lung cancer treatment with classical prescriptions in recent 5 years.

Objective To study the feasibility and short-term effects of arthroscopic anterior cruciate ligament (ACL) reconstruction by using the Ligament Advancement Reinforcement System (LARS) artificial ligaments. Methods Arthroscopic ACL reconstruction was carried out in 16 patients with ACL injuries by using the LARS artificial ligaments. Bone tunnels of the femur and the tibia were prepared with an identical interval between each other. The artificial tendon was inserted into the tunnels, and then, fixed with 2 interface screws after being tightened, with the free end of the tendon within the articular cavity. The complicated injuries were treated simultaneously. Results The operation time was 51~86 min (mean, 64 min). No postoperative complications such as synovitis, ligament rupture, or movement restriction occurred. A follow-up checkup was made in the 16 patients for 1.5~6 months (mean, 3.8 months). The International Knee Documentation Committee (IKDC) scores showed 6 cases of grade C and 10 cases of grade D before the surgery, while 6 cases of grade A, 9 cases of grade B, and 1 case of grade C after the surgery ( ? 2 =6.264, P

Objective To investigate the effects of dexmedetomidine preconditioning on nitric oxide (NO)/endothelin (ET)-1 imbalance and remote lung injury induced by lower limb ischemia-reperfusion (LIR). Methods Sixty patients who scheduled for unilateral lower extremity surgery matched American Society of Anesthesiologists (ASA) Ⅰ-Ⅱ, were randomized into two groups:control group (R group, n=30) and dexmedetomidine preconditioning group (PD group, n=30). Lumbar plexus combined with sciatic nerve block was performed guided by a nerve stimulator in both groups. In group PD, dexmedetomidine intravenous infusion was started at a dose of 0.125 mL/kg (4 mg/L) for 10 minutes before using tourniquet, whereas group R received an equivalent volume of normal saline. Artery blood gas analysis, respiratory index and oxygenation index were measured, and NO, ET-1, interleukin-8 (IL-8) and malondialdehyde (MDA) concentrations were determined from plasma samples 10 minutes before tourniquet inflation (T0), 15 minutes (T1), 2 h (T2), 6 h (T3) and 24 h (T4) after tourniquet deflation. Results Compared with T0, RI was higher at T3 in group R and OI was lower at T2-4 (P＜0.01). There were no significant differences in RI and OI of group PD between different time points (P＞0.05). In R and PD groups, ET-1, IL-8 and MDA concentrations were increased, while NO level and NO/ET-1 ratio were significantly decreased after tourniquet deflation (P＜0.05). Compared with group R, RI was lower and OI was higher at T3 in group PD (P＜0.01). The levels of ET-1, IL-8, MDA, NO and NO/ET-1 ratio were significantly different after tourniquet deflation between group PD and group R (P＜0.05). In group R, there was positive correlation between ET-1 and IL-8 levels with RI, and negative correlation between ET-1 and IL-8 levels with OI (P＜0.01). There was positive correlation between NO level, NO/ET-1 ratio and RI level (P＜0.01). Conclusion Lung function impairment induced by tourniquet application could be attenuated by dexmedetomidine preconditioning based on protecting endothelial cells and inhibiting lipid peroxidation.
