Objective To investigate the relationship between executive function and depressive symptoms in patients with major depressive disorder( MDD) under the Tower of London Test ( TOL) . Meth-ods Thirty depression patients and thirty age?, gender?, education?matched normal controls participated in the study. All subjects received the Tower of London Test. The severity of depressive and anxiety symptoms were assessed by Hamilton Rating Scale for Depression ( HAMD) ,Hamilton Anxiety Rating Scale( HAMA) and Beck Depression Rating Scale( BDI) . Results ( 1) The numbers of correct response and total response of the TOL in MDD(9.1±5.1,12.1±5.3) were significantly lower than those of the control group(13.8±5.0, 17.3±3.9)(P<0.05).The response time of the TOL test in patients with MDD((10.4±2.8)s) was signifi?cantly longer than that of the control group((8.5±2.2)s)(P<0.05). (2)The scores of HAMD ,BDI and HAMA were negatively correlated with numbers of total response( r=-0.403,-0.544,-0.495,) in patients with MDD ( all P<0.05) . Conclusion The executive function of patients with MDD is impaired and nega?tively correlated with depressive and anxiety symptoms under the Tower of London Test.

BACKGROUND:Increasing evidence suggests that Sanguis draxonis is of great significance for treating pressure sores, burns and ulcers.
OBJECTIVE:To observe the influences of Sanguis draxonis on vascular endothelial growth factor, epidermal growth factor, substance P and hydroxyproline in rats undergoing tissue-engineered skin transplantation and to verify its promotion of wound repair.
METHODS:The tissue-engineered skin transplantation model of rats were established. Rats in treatment groups were given external application, single oral use of 0.1 g/(kg·d) Sanguis draxonis and combined use, respectively. No treatment was given in control group. After continuous treatment for 7 days, the expression levels of vascular endothelial growth factor, epidermal growth factor, substance P and hydroxyproline in skin tissue were determined.
RESULTS AND CONCLUSION:Compared with the control group, the levels of vascular endothelial growth factor, epidermal growth factor, and hydroxyproline were significantly increased (P<0.05 or P<0.01), while substance P had no change in the treatment groups (P>0.05). These results demonstrate that Sanguis draxonis can promote tissue-engineered skin to repair skin wound by upregulating the expression levels of vascular endothelial growth factor, epidermal growth factor, and hydroxyproline.

Diverticulitis of colon,the inflammation of colonic diverticulars,is connected with dietary,age and disorder of colonic environment.Due to the different cultures between western contries and orient nations,the morbidity,predilection site,clinical manifestation and management are different in diverticulitis of colons.Computed tomography(CT)has been the key diagnosic method,and it is able to guide transfixion pins to treat diverticulitis of colon.After medical treatment,most of patients can be relaxed,and only someone need operations.

BACKGROUND:How to avoid denervated muscular atrophy is a key factor to improve the therapeutic efficacy on peripheral nerve injuries. OBJECTIVE:To study the effect of basic fibroblast growth factor (bFGF) gene-transfected bone marrow mesenchymal stem cels against denervated muscle atrophy. METHODS: bFGF genes were transfected into rat bone marrow mesenchymal stem cels using viral transfection method, and then MTT, immunohistochemical staining, hematoxylin-eosin staining, RT-PCR, western blot, and ELISA methods were used to detect the transfection efficiency and product expression. Thirty-two Sprague-Dawley rats were selected to make animal models of sciatic nerve injury, and subjected to multi-point intramuscular injection of bFGF-transfected bone marrow mesenchymal stem cels (experimental group) or cel culture fluid (control group). At 2, 4, 6, 8 weeks after transfection, the gastrocnemius muscle tissues were harvested to detect action potential, residual wet weight, and cross-sectional area of muscle fibers. RESULTS AND CONCLUSION:The bFGF gene was successfuly transfected into bone marrow mesenchymal stem cels using the viral transfection method. The residual wet weight, cross-sectional area and residual action potential of the gastrocnemius muscle were significantly better in the experimental group than the control group (P < 0.05). These findings indicate that bFGF gene-transfected bone marrow mesenchymal stem cels transplanted into the denervated muscle can retard the development of muscle atrophy.

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.

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
