Lateral habenula ( LHb ) , which is situated in the dorsal diencephalon of all vertebrates, is an important component of the habenular complex. The neural network outlined in previ-ous studies indicates that LHb acts not only as an important relay station to link the forebrain with the midbrain regions that in-volved in regulating behavioral responses to reward and mediating the transmassion of negative feedback information, but also is closely connected with 5-HT system. Indeed, recently studies demonstrate that experimental manipulations of LHb are followed by behavioural alterations in relation to drug addiction, reward-a-version responses, pain, sleep, depression and so on. This arti-cle mainly reviews the mechanisms of LHb involved in all kinds of physiological activities.

Objective To explore the daily management mode of hygienic materials of locomotive logistics unit. Methods Through the method of building deposit area and buffer area in regular depot, hygienic materials with validity regulation such as drugs could be included in hospital regular inventory manage ment; the hygienic materials were dynamically replaced according to the hospital's daily cost. Results Under the condition of ensuring the adequateness of hygienic materials, the method was able to meet the validity requirement and avoid wasting as well. Conclusion Hospitals have favorable condition and professional management in reserving different types of hygienic materials. As it costs time to assemble materials, this management mode is more suitable for the management of hygienic materials of locomotive logistics unit.

The dysfunction of the upper limbs in tetraplegia depends on the level of spinal cord injury, and needs different type of upper limb orthosis.

Objective To study the inlfuence factors on detection of activity of four coagulation factors in prothrombin complex concentrates (PCC) by several factors. Methods Using Pharmacopoeia of the People’s Republic of China (2010) as reference, the activity of four coagulation factors in PCC were investigated by choosing different pre-treatments, different diluents, different salt concentration, different standard human plasma and different company reagents. Results The activity of FII, FVII, FX were decreased and FIX was increased in the condition of adding protamine sulfate, and there were no differences of four coagulation factors whether warm bath in 37 for 15 min or not. However, the differences of four coagulation factors were significant by using deficient plasma, saline, distilled water and commercial dilution buffer(P<0.05). The activity of coagulation factor II, X in 1 mol/L salt concentration of PCC were significantly lower than in 0.25 mol/L(P<0.05), while coagulation factor VII, IX were not. The activity of FII, FVII, FIX, and FX were different by using different standard human plasma to make standard curve. The activity of four coagulation factors existed significant difference(P=0.00) by using SIEMENS company reagents and domestic reagents. Conclusion Choosing different pre-treatments, different dilution buffers, salt concentration, standard human plasma and commercial kits will inlfuence the detection result of coagulation factors.

Objective To assess the therapeutic effects of Yiqifumai combined with Alprostadil injection on patients with chronic cardiac insufficiency and angina pectoris.Methods One hundred and fifty patients with heart dysfunction (NYHA [Ⅱ-Ⅲ) and angina pectoris were randomly divided into three groups,the control group (n=50),the Yiqifumai group (n=50),and the Yiqifumai plus Alprostadil group (n=50).Parameters including clinical effectiveness,electrocardiograph (ECG),heart function and hemodynamics were evaluated.Results The overall clinical effectiveness rate in the Yiqifumai plus Alprostadil group (94 ％) was higher than those in the Yiqifumai group (78 ％) and the control group (54％) (P＜0.05 for both).The overall effectiveness rate in ECG changes was higher in the Yiqifumai plus Alprostadil group (84％) than in the Yiqifunai group (58％) and the control group (42％) (P＜0.05 for both).While no significant difference in the left ventricular ejection fraction (LVEF) was found among the three groups before treatment,evident improvement in LVEF was observed in the Yiqifunai group and the Yiqifumai plus Alprostadil group 14 days after treatment,compared with pre-treatment data [(49±9)％ vs.(40±10)％ and (59±9)％ vs.(41±10) ％,respectively; P＜0.05 for both].However,there was no significant difference between the two groups (P＞0.05).There was no improvement in LVEF in the control group after treatment (P ＞0.05).No difference in hemodynamic parameters,including cardiac output,cardiac index and left ventricular stroke work index,was found among the three groups before treatment (P＞0.05),but they showed improvement in the Yiqifunai group and the Yiqifumai plus Alprostadil group after treatment (P＜0.05 for both),with greater improvement in the latter group.The improvement was not significant in the control group before and after treatment (P＞0.05).Conclusions Yiqifumai combined with Alprostadil in the treatment of cardiac insufficiency with unstable angina pectoris has advantages in improving clinical symptoms,heart function and hemodynamics.

Aim To investigate the effects of Vam3 on ATP-induced inflammatory response in macrophages and the underlying mechanisms. Methods LPS primed mouse peritoneal macrophages were stimulated with ATP,and IL-1βlevel in supernatants was meas-ured by ELISA.Activity of caspase 1 was measured u-sing caspase 1 activity assay kit.Reactive oxygen spe-cies (ROS )level was detected with fluorescent probe DCFH-DA.MTT assay was used to detect cell prolifer-ation,and intracellular Ca2+concentration was meas-ured using laser scanning confocal microscope.Results Extracellular ATP led to increase in IL-1βrelease, caspase 1 activity and ROS production.It also led to rapid increase in intracellular Ca2+concentration and induced cell death.These effects were inhibited by Vam3 .Conclusion Vam3 inhibits ATP-induced in-flammatory response in macrophages,which may sug-gest the blocking effect of Vam3 on caspase 1 ~IL-1βinflammatory signaling pathway in macrophages.

0.05.Only 1 of 28 (3.6%) showed positive survivin signal in the control group.The difference of the positive rate of survivin between groups of TCCB and control was significant ( P

Objective To investigate the isolation and antimicrobial resistance of hypermutable Pseudomonas aeruginosa strains.Methods The cultured bacteria were identified by API 20NE system.The susceptibilities of bacteria were detected by disk diffusion method and the results were confirmed with the rules of NCCLS/CLSI.The hypermutable strains were identified byhigh concentration of rifampin-resistant growth assay.Results Among analyzed 100 strains,37 strains(37.0%) were hypermutable.The resistant rates of hypermutable strains to imipenem,meropenem,cefoperazone/sulbactam,piperacillin/tazobactam,ceftazidime,cephfime,aztreonam,amikacin and ciprofloxacin were significantly higher than those of non-hypermutable strains.The multidrug resistance rates of hypermutable strains were also higher than those of non-hypermutable strains.Conclusion The hypermutable strains of Pseudomonas aeruginosa sourced from chronic respiratory tract infections dominantly.The hypermutable strains were hyper-resistant and multidrug resistant to many antibiotics,so strengthened monitoring should be encouraged to control the prevalence of hypermutable Pseudomonas aeruginosa strains.

Objective To investigate the effect of osteoinductive calcium phosphate ceramics (OICPC) on tendon healing in bone tunnels. Methods Anterior cruciate ligament reconstruction with semitendonous tendon was performed in the knee joints of 30 New Zealand rabbits by suspended fixation. OICPC grains were implanted into the bone tunnel of 15 rabbits which were the experimental group and the other 15 rabbits without OICPC implants severed as the control group. Specimens were collected four weeks, eight weeks and 12 weeks after surgery. Sections were stained with H. E., Sirius Red and Masson. Histological changes in the interface tissue between the bone tunnel and the tendon graft were observed, and the morphology of interface tissue was classified according to Yamakado method. Histomorphometry was done on Masson stain sections to measure new bone formation around the grafted tendon. Results In OICPC group, histological sections obtained four and eight weeks after surgery showed statistically greater new bone formation than those in the control group. Abundant penetrating Sharpey fibers appeared at eight weeks and direct connection was found at 12 weeks in the experimental group. On the other hand, Sharpey fibers appeared only at 12 weeks in the control group. Conclusion OICPC has a capability of enhancing biological fixation of a tendon to the bone tunnel.
