[Objective]To establish a scoring standard of operative risk assessment for the orthopaedic surgery and evaluate the reliability of it.[Method]Anivariable analysis was performed for the preoperative and intraoperative clinical data of 768 patients undergoing orthopaedic surgery from Jan.2001 to Dec.2008,the risk factors associated with orthopaedic surgery were selected.Then multivariable analysis with logistic regression was performed for the selected risk factors.The scoring standard was made through these data.Reliability of the standard was evaluated by predicting of 160 patients in spinal surgery from 2006 to 2008,comparing with the real situation of each operation.[Result]Anivariable analysis showed age,heart function,blood pressure,electrocardiogram,sternum,liver function,renal function,albumin,blood sugar,number of operative variables within four weeks,magnitude,blood loss preoperation,timing of operation were risk factors.[Conclusion]The ORAOS could appropriately predict the occurrence of patients' postoperative complication before operation.

To discuss long-term changes of refractive status in children after congenital cataract intraocular lens ( lOL) implantation and analyze its related influence factors.METHODS: Seventy cases ( 110 eyes ) with congenital cataract from January 2013 to January 2014 in our hospital were selected, according to the age of patients, they were divided into group A (<2 years old), group B (2~6 years old) , group C ( 7 ~ 12 years old ) . They were all given cataract extraction combined with lOL implantation in congenital cataract. Corneal curvature, axial length, refractive status of three groups after operation were compared, the influence factors ocular axis changes were analyzed. RESULTS: There were no statistically significant differences in corneal curvature of groups A, B, and C after operation ( P>0. 05 );The differences had statistical significances of the corneal curvature of group A after surgery and 3mo after operation (P<0. 05), there were no significant differences of the corneal curvature of group B, group C after surgery and 3mo after operation (P>0. 05);the corneal curvature 3mo after operation of group A was significantly higher than that of groups B and C (P<0. 05), there were no significant differences in the corneal curvature between group B, and group C after 3mo ( P>0. 05 ); There were no statistical significances on axial length after operation in groups A, B, and C (P>0. 05);Ocular axial length difference of group A 3mo after surgery was significantly higher than that of groups B and C ( P < 0. 05 ), ocular axial length had no statistical difference of group B, group c 3mo after surgery ( P>0. 05). Refractive status of three groups after operation showed myopia moving trend, refractive change rate and refractive diopter of group A after operation was significantly higher than that of group B, group C, the difference was statistically significant (P<0. 05). CONCLUSlON: After congenital cataract extraction combined with lOL implantation, patients present myopia refractive state trend. Performance of children below 2 years old is significant. The main factor of myopia is axial growth.

Calreticulin (CRT) participates in the progression and apoptosis of many kinds of tumor cells. Recent studies indicate expression of CRT on tumor cells acts as an "eat me" signal for dendritic cells,allowing them to phagocytose tumor cells. It can induce immunogenic tumor cell death by adsorbing recombinant calreticulin to tumor cells or by enforcing the translocation of endogenous calreticulin to the cell surface. In animal experiments,CRT related tumor vaccine has good therapeutic effects in some tumor bearing mice,which can be used in tumor immunotherapy and targeted therapy.

OBJECTIVETo observe the effect of Xingnaojing Injection combined with minimally invasive percutaneous drainage on brain edema and content of serum aquaporin-4 (AQP4) in patients with moderate hypertensive basal ganglia hemorrhage, and discuss the treatment mechanism of Xingnaojing injection combined with minimally invasive percutaneous drainage for cerebral hemorrhage.

METHODForty-two patients with moderate (25-50 mL) hypertensive basal ganglia hemorrhage (< 24 h) were selected and randomly divided into two groups: the observation group (n = 22) and the control group (n = 20). The neurological severity score were evaluated by the NIHSS (national institutes of health stroke scale), the volume of brain edemas were measured by head CT, the serum levels of AQP4 were determined by ELISA method on admission and 1 and 2 weeks after treatment.

RESULTOn admission, there was no significant difference in the scores of NIHSS, the volume of brain edemas and the level of serum AQP4 between the observation group and the control group. At the end of the first week after the treatment, the score of NIHSS of the observation group were lower than that of the control group, with significant different (P < 0.05); the observation group showed reduced volume of brain edemas than that on admission (P < 0.05), whereas the control group the control group showed increased volume of brain edemas than that on admission; the control group displayed increased level of serum AQP4 than that on admission, but without significant difference; the observation group displayed decreased level of serum AQP4 than that on admission (P < 0.05). At the end of the second week after the treatment, the control group showed decreased score of NIHSS than that on admission and at the end of the first week after treatment (P < 0.05). Compared with the control group, the observation group showed a much lower score of NIHSS (P < 0.01), the control group displayed reduced volume of brain edemas than that on admission and at the end of the first week after treatment, but the observation group was even lower than the control group. Both of observation and control groups displayed significantly reduced level of AQP4 (P < 0.05), but the observation group showed a lower AQP4 level than that of the control group (P < 0.05).

CONCLUSIONThe therapy of Xingnaojing injection combined with minimally invasive percutaneous drainage could remarkably reduce brain edema, and promote neural functional recovery, thus could be selected as a therapeutic regimen for patients with moderate hypertensive basal ganglia hemorrhage.
