Objective To analyze the effect of both limited selective posterior rhizotomy(LSPR)and limited selective soft tissue release(LSTR)on healing motor function related to spasmo-cerebral palsy in both legs.Methods Thirty-eight cases CP with LSPR and LSTR were collected in the past 3 years;21 males,17 females;aged 3.0-8.11 years old,on the average of 5.11 years old.Perioperative motor function were evaluated according to motor function scores.Results LSPR and LSTR played a role in improving motor function obviously,and had little difference in orthomorphia after SPR for 6 months.Conclusion LSPR and LSTR may improve cramp and abnormality in both legs,and enhance motor function,so the secondary operation agony can be avoided,and the family economic burden relived.

Objective To investigate the clinic effect of Linezolid for community acquired methicillin resistant staphylococcus aureus (MRS A) pneumonia. Methods The clinic data of the patient- were collected from the First Affiliated Hospital of Sun Yat-Sen University, in addition, the body temperature and white blood cell counts were obtained as the index of treatment. Results It was proved that Linezolid was effective in treating community acquired MRSA pneumonia and showed well tolerance with few adverse events. Conclusion Linezolid demonstrated good clinical and antibacterial activity but very few adverse reactions in elderly patients with community acquired MRSA pneumonia.

Objective To investigate the variation of biomarker of coagulation, anti-coagulation, fibrinolysis in elderly critical patients and find out whether they are related to the disease severity. Methods Sixty-seven patients were no less than 60 years old. Eligible criteria: coincidence with the diagnostic criteria of systemic inflammatory response syndrome (SIRS) and APACHE Ⅱ score was no less than 10 scores. Blood sample was drawn from the venous for the test of biomarker (APTT, PT, TT, D-D, Fib, AT-Ⅲ , PC, PAI-1). According to the existent status,all the patients were divided into two groups:survival group (43 cases) and death group(24 cases) ,meanwhile,according to the diagnostic criteria of MODSE,all the patients were divided into MODSE group (30 cases) and non-MODSE group (37 cases). Results There were significant differences in APACHE Ⅱ score between MODSE group and non-MODSE group, survival group and death group [(25.83 ± 1.19) scores vs(18.1±20.73) scores and(18.81±0.72) scores vs(26.50 ± 1.42) scores](P <0.01). The PT and D-D in MODSE group anti death group were higher than those in non-MODSE group and survival group, the differences were significant (P <0.05),while the activity of AT-Ⅲand PC in MODSE group and death group were lower than those in non-MODSE group and survival group, the differences were significant (P <0.05). The PT,D-D and PAI-1 were positively correlated to APACHE Ⅱ score (related coefficients were 0.328, 0.308, 0.335,P <0.05). The AT-Ⅲ and PC were negatively correlated to APACHE Ⅱ score (related coefficients were -0.469, -0.559,P <0.01). Conclusions The abnormality of eoagnlation-fibfinolysis system exists in elderly critical patients. The extended PT, elevated D-D and PAI-1 ,descended PC and AT-Ⅲ are the hints of disease severity and poor prognosis.

Objective The combination of vasopressin and epinephrine has long been thought to be more effective then epinephrine alone in cardiopulrnonary resuscitation (CPR), evidence is not enough to make such a clinical recommendation. This meta-analysis compared the efficacy of vasopressin and epinephrine used together versus epinephrine alone in cardiac arrest (ca) in order to verify the truth. Method MEDLINE and EMBASE were searched for the data of randomized trials in comparing the results of co-administration of vasopressin and epinephrine with epinephrine alone in adults with cardiac arrest. The primary outcome was the restoration of spontaneous circulation (ROSC). Results Six randomized trials in 485 articles were analyzed. We failed to get the results supporting the effectiveness of this combination therapy, except for the rate of 24 hours survival (OR: 2.99,95%CI:1.43 ~ 6.28). No evidence supported that vasopressin combined with epinephrine was better than epinephrine alone in ROSC. Conclusions This systematic review indicates the combination of vasopressin and epinephrine is better for the rate of 24 hpurs survival in only 122 patients. Further investigation is needed to support the use of combination therapy for cardiac arrest.

Objective To evaluate the efficacy and safety of intra-arterial thrombolysis with recombinant tissue-plasminogen ac-tivator(rt-RA) for treatment of acute cerebral infarction (ACI) .Methods The randomized controlled trials (RCT ) of intra-arterial thrombolysis with rt-PA for treatment of ACI were selected from Cochrane Library ,Medline ,Embase and CBM by the computer re-trieval .A meta analysis of the data were analyzed by using RevMan 5 .1 software .Results A total of 473 patients in 9 selected RCTs were involved in the systematic review .Meta-analysis results disclosed suggested that the effectiveness of intra-arterial thrombolysis treated ACI group was better than that of intravenous thrombolysis group [RR= 1 .26 ,95% CI(1 .09 ,1 .45) ,P=0 .002] .No difference was observed between the two groups in intracranial hemorrhage and mortality rate .Conclusion The current evidence showed that ,the clinical effect of intra-arterial thrombolysis with rt-PA for treatment of ACI was obviously superior to that of intravenous thrombolysis ,but the result still needs to be confirmed by large-sample RCTs .

Objective To determine the levels of soluble thrombomodulin(sTM) in patients with acute pulmonary embolism (PE), and evaluate sTM clinical significance.Methods The sTM levels were determined with enzyme linked immunosorbent assay in PE patients, and compared with healthy control group. Eighteen PE patients were divided into massive PE group and non - massive PE group, non - respiratory failure group and respiratory failure group, and compared the sTM level in the groups. Results Level of sTM in PE patients was higher than that of control group (P

Objective To observe the protective effects of soluble Nogo-66 receptor (NgR1 )antagonist (sNgR1-Fc) on cortical axons after cortical infarction in rats,and to study the phenomenon and molecular mechanism of its protective effects on and regeneration of axons.Methods The cortical infarction was induced by photochemistry,termed photothrombotic cortical injury (PCI).Fifteen Sprague Dawley rats were randomly divided into three groups:Sham-operated group,PBS (phosphate buffered solution) group,and s-NgR1-Fc group.In PBS group,PBS was injected into the lateral ventricle of rats; and in sNgR1-Fc group,sNgR1-Fc was injected instead of PBS. The ipsilateral cortex with lesion was harvested for histomorphometry and transmission electron microscope observation 7 days after PCI. Proteins including GTP-RhoA,p-JNK,p-c-JUN and p-ATF-2 were detected by Western blot,as well as Total-J and Total-RhoA.Results The cortical infarction in rats was successfully induced by photochemistry.Compared with sham-operated group,the pathological changes in PBS groups were more serious,including extensive edema or disappearance of axoplasm of fiber without medulla sheath involved and extensive thickening or layer derangement in axoplasm of fiber with medulla sheath involved.These changes were improved significantly after sNgR1-Fc treatment.The levels of GTP-RhoA,p-JNK1,p-JNK2,p-c-JUN and p-ATF-2 in the PBS group were significantly higher than those in the sham-operation group ( P < 0.05 ),whereas the levels of Total-RhoA,Total-JNKl and Total-JNK2 were not different significantly between these two groups (P >0.05 ).The sNgR1-Fc treatment up-regulated the levels of these proteins ( P < 0.05 ).Conclusions There is pathological change in axon induced by cerebral hypoxia-ischemia for a long period after cortical infarction.The mechanisms may be associated with RhoA/ROCK/JNK/c-Jun signal way,which is activated by ischemia injury and related to the inhibition of regeneration in axon.Our study shows that NgR1-Fc may inhibit this pathway significantly,and then promote the regeneration of axon partially.
