Objective To evaluate the effects of milrinone on plasma levels of C reactive protein (CRP) , TNF-?, IL-8 and IL-10 during and after operation for tetralogy of Fallot performed under cardiopulmonary bypass (CPU) in children.Methods Sixteen ASA Ⅲ-Ⅳ pediatric patients aged l-12yr scheduled for operation for tetralogy of Fallot under CPB were randomly divided into two groups : (1) milrinone group ( M, n = 8) and (2) control group (C, n = 8) . In group M a loading dose of milrinone 50 ?g?kg-1 was given i.v. within 10 min, immediately after aortic unclamping, followed by continuous infusion at 0.2?g?kg ?min-1 . In group C equal volume of lactated Ringer's solution was infused instead of milrinone. Blood samples were taken from the CVP line before anesthesia (T0), 5 min after release of aortic cross-clamp (T1), 5 min after discontinuation of CPB (T2) , at the end of surgery (T3) and 24 h and 48h after operation (T4,5) for determination of plasma levels of CRP, TNF-?, IL-8 and IL-10 by radioimmunoassay.Results There was no significant change in plasma TNF-a concentration in both groups. Plasma CRP level increased significantly at 24 and 48 h after operation (T4 , T5 ) , in both groups and was significantly higher in group M than that in group C. Plasma IL-8 level increased significantly only at T2 and T3 compared to pre-anesthesia value (T0) in group M while in group C it increased significantly from T1-5 (P

Objective To investigate the altered expression of TLR4 in alveolar macrophages of diabetic rats after lipopolysaccharide (LPS) stimulation and the effect of these changes on defending the infection. Methods Thirty-two male Wistar rats were divided into 4 groups, group A: the control group; group B: the diabetic group; group C: the LPS stimulated group; and group D: the diabetic group with LPS stimulation. TLR4 in alveolar macrophages were measured by immunocytochemistry, RT-PCR and Western blot analysis. Results The expressions of TLR4 in group B and group C were higher than that in group A (P < 0. 001). The expression of TLR4 in group D was obviously higher than that of group B and group C (P < 0.001). Conclusion The expression of TLR4 of diabetic rats was higher than that of normal rats and became more higher after LPS stimulation, which is indicated that diabetic bodies were in the proinflammatory state, the mechanism remains to be explored in detail.

Objective:To study direct medical cost of hypertensive patients without complicated disea-ses,to analyze substitution impacts of outpatient expenditure on inpatient expenditure,and then to make recommendations to health policy makers and hypertensive patients for managing hypertension.Methods:The claims data of hypertensive patients insured by the rural new cooperative medical scheme in a city in northern China from 2008 to 201 3 were analyzed,descriptive statistics employed to analyze direct medical cost of hypertensive patients and hypertensive patients without complicated diseases which was one of the three groups divided by medical treatment conditions (hypertension without complicated diseases,hyper-tension with complicated diseases,and other diseases),and the differences between groups compared by t test.The fixed effect two-part model was employed to analyze the substitution effect of outpatient services on inpatient services,and specific effects of outpatient times and reimbursement expenses on the inpatient expenditure were calculated by Logistic regression analysis.Results:For the hypertensive pa-tients,the average cost of outpatients was 283.49 Yuan in 2008 and rose to 370.93 Yuan in 201 3.After being divided into three groups,for hypertensive patients without complicated diseases,the average cost of outpatient was 449.79 Yuan in 2008 and rose to 582.53 Yuan in 201 3.In the total cost of the outpa-tient,45.73% was for the hypertensive patients without complicated diseases;in the total cost of the in-patient,only 9.29% was for the hypertensive patients without complicated diseases.By calculating the marginal effect of parameter estimation through the fixed effect two-part model,the inpatient cost could be significantly reduced by increasing the visit times of outpatient utilization or the cost of outpatient reim-bursement.For example,in 201 3,a 1 % rise of outpatient visit times increased outpatient expenditures by 6.48 million Yuan,which could reduce inpatient expenditures by 39.86 million Yuan.The substitu-ted ratio of outpatient cost on inpatient cost had been around 5 in 201 0 and later.Conclusion:The health policy-makers and hypertensive patients should pay more attentions to the substitution of outpatient cost for inpatient cost,especially for the hypertensive patients without complicated diseases whose direct medical cost was mainly due to outpatient rather than inpatient costs.

AlM: To explore the clinical application effect of phacofragmentation combined with vitrectomy in the treatment of traumatic lens dislocation.
METHODS:Totally 16 cases (16 eyes) of traumatic lens dislocation treated with phacofragmentation combined with vitrectomy were retrospectively analyzed, including 6 cases of high intraocular pressure ( lOP) and 10 cases of vitreous hemorrhage, and 1 case of retinal detachment. All patients were given conventional flat line standard three channel vitreous operation incision to remove the anterior, middle part and peripheral vitreous around lens dislocation. The crystalline lens were drawn to the center cavity of vitreous body and treated by ultrasonic disintegrator. ln the operation, the retina was examined and 8 of them had no retinal damage and in the first stage underwent fixation of posterior chamber intraocular lenses.
RESULTS: All crystalline lens dislocated were completely grinded and suctioned. There was no retinal detachment occurred in 3mo followed up. 16 eyes had normal lOP (12-20mmHg) at 1wk after operation. The average visual acuity was improved and with 8 cases got improved of 0. 2 or more 1wk after operation.
CONCLUSlON: Our research shows that phacofragmentation combined with vitrectomy is a safe and effective method for the treatment of traumatic lens dislocation. The patients with nondestructive retina in the operation are feasible to do first stage operation of intraocular lens suture fixation, which contributes to the best visual acuity.

AIM: To retrospectively evaluate the effect of lens extraction combined with vitrectomy to treat traumatic lens dislocation with secondary glaucoma.
METHODS: Thirty - one eyes ( 31 cases ) of lens dislocation caused by blunt trauma with secondary glaucoma were treated respectively with cataract extraction combined with anterior vitrectomy, trabeculectomy and intraocular lens implantation. The visual acuity and pressure were observed 1wk, 1 and 3mo after operative.
RESULTS: Thirty - one eyes were all complete the operation successfully, and 6 eyes were given combined trabeculectomy, 9 eyes were implanted anterior chamber intraocular lens implantation ( IOL ) and 15 eyes were given posterior chamber suture fixation. Sixteen eyes were implanted in one-stage operation, while 8 eyes were implanted in two-stage operation. All intraocular pressure ( IOP ) were controlled to the normal level after operation and 23 eyes had visual acuity of more than 0. 3. CONCLUSION: Lens extraction combined with vitrectomy is an effective method for treatment of lens dislocation with secondary glaucoma. In order to control the IOP and get well visual function, we should choose IOL implantation or trabeculectomy according to the patient's condition.
