[Objective] To investigate and analyze the clinical effect of double-plate method on complex tibia plateau fracture. [Methods] A total of 62 pa-tients that had complex tibia plateau fracture from October 2010 to December 2012 in our hospital, were divided into the experimental group and the control group randomly, 31 patients per group. Patients of the experimental group received double steel plate internal fixation with double incision, and patients of the control group received locking plate internal fixation, and the clinical efficacy of two groups were compared. [Results] The excel ent rate of the experimental group was better than that of the control group(87.1% vs 64.5% χ2=4.309 P=0.038), and the difference of complications rate of two groups had no statistical significance(3.2%vs 6.5% χ2=0.350 P=0.554). [Conclusion] The clinical effect of double-plate method for complex tibia plateau fracture is good, and the complications rate is low, worthy of clinical promotion.

After-department examination palys an important role in clinical teaching.The level of clinical teaching is one of the most important markers to evaluate the whole quality of the hospital.To improve the ability of teaching and teaching concept,we summarized the problem of after-department examination and put forward a series of reformation methods.

Objective: To investigate the role of host derived matrix metalloproteinases (MMPs) in the pathogenesis of pulpitis. Methods:The expressions of MMP-2 and MMP-9 were examined by immunohistochemical method and the activity of MMP-2 and MMP-9 were measured by gelatin zymography in 20 clinically healthy and 20 inflamed human dental pulps of extracted mandibular 3rd molars.Results:In clinically healthy and inflamed human pulps both MMP-2 and MMP-9 were expressed in odontoblasts and fibroblasts. The pro-MMP-9 was detectable in both inflamed and healthy pulps. The level of pro-MMP-9 was higher in inflamed pulps than that in the healthy(P0.05).Pro-MMP-2 and active MMP-2 were not detectable in the pulps of the two groups. Conclusion:MMP-9 may involve in the pathogenesis of pulpitis.

Objective To investigate the effect of batroxobin on the plasma levels of endothelin (ET) and calcitonin gene-related peptide(CGRP) in patients with acute cerebral infarction(ACI). Methods 60 patients with ACI were randomly divided into therapy group(n = 30) and control group(n = 30),500 ml of 5% GS plus 1.0g ramme of Troxerutin was intravenously dripped par day and ticlopidine 250mg/day in the control group. Based on the control group therapy,Batroxobin was intravenously dripped with 10U on the 1st day and 5U on the 3rd and 5th day for seven days. The plasma levels of ET and CGRP were detected pre and post treatment by radioimmunoassay. Results Plasma levels of ET and CGRP in batroxobin therapy group post treatment ( 81.25±27.38 ) ; ( 44. 13±13.30) ng/L were significantly different from those pre treatment(109. 83±38.24) ; (24. 73±13.59) ng/L (all P＜0. 01 ) ,and were also significantly different from those post treatment in the control group(98.07±30. 39) ; (37.02±12. 41 )ng/L (all P＜0. 01 ). Conclusion Batroxobin can accommodate the equilibration between ET and CGRP, and protect brain cell and blood vessel endothelial cell.

Objective To explore the influence and potential protective effects of non-specific panMetrix Metalloproteinases(MMPs) inhibitor Doxycycline on hyperoxic lung injury and lung development in neonatal rats.Methods Neonatal SD rats were divided into 4 groups randomly within 12 hours after birth:air with normal saline(AN),air with doxycycline(AD),hyperoxia with normal saline(ON),and hyperoxia with doxycycline group(OD).Hyperoxia groups(ON and OD) were exposed to ≥90% O2.Doxycycline 20 mg/kg or equal volume of 0.9% saline(Doxycycline concentration 2 mg/ml) was administered by gastric gavage,twice daily from day 1 to experimental day,but it didn't exceed 14 days.Stereological study was carried out at day 1,3,7,14 and 21 after birth.Results Enlarged mean alveolar area was noted both in hyperoxia and Doxycycline groups.OD group had larger star volume than ON group on day 14.Except ON group,all other groups had increased alveolar septum and the condition was worsened by hyperoxia with Doxycycline.The percentage of collagen in lung parenchymal tissue in ON group increased persistently.This increasing trend was stopped in OD group on day 14,and collagen percentage had no significantly difference between OD and AN groups on day 14 and 21.Conclusion Both hyperoxia and Doxycycline influence neonatal lung development,percentage of coUgen in lung parenchymai can be reduced by Doxycycline in hyperoxic lung injury.

Objective To explore the primary treatment of type 2 diabetes, clinical effect of rosiglitazone combined with metformin treatment.Methods In 40 patients with type 2 diabetes mellitus patients implementation of routine treatment for metformin, and 40 patients in the control group based on the use of rosiglitazone intervention treatment, two groups of patients in our hospital from January 2015 to December 2016 were compared between the two groups.Results Treatment efficiency, obvious effective rate of observation group were higher in the observation group was 95%, while only 82.5% of the control group,comparison between groups showed significant differences(P<0.05);the two groups of patients with fasting blood glucose levels, 2 hour postprandial blood glucose level There were no significant difference before treatment, after treatment group observation group significantly improved, comparison between groups showed significant differences(P<0.05).Conclusion Rosiglitazone Combined with metformin in newly diagnosed type 2 diabetes clinical observation, which can help to improve the clinical symptoms of patients, reduce blood glucose, compared with pure medication.To improve the treatment effect, it is worthy of reference.

Complement-induced polymorphonuclearcytes (PMN) aggregate in microvasculature of vital organs, produce microemboli, and block microcirculation blood flow. Activated PMN release oxygen free radicals, prostaglandins and proteases, in turn, damage endothelial and parenchyma cells. This is an important factor in pathogenesis of multiple system organ failure. We have found that Sinomeuine and Sodium Ferulate prevented PMN aggregation induced by activated complement. Adding the drugs into PMN suspension treated with cytochalasin B, the zymosan activated plasma, PMN aggregation was prevented. The changes of light transmission were smaller than those of control without drugs recorded with platelet aggregometer. The 50% of PMN aggregation inhibition with Sinomeuine was 0.76mg/ml (1.gmmol/L), and 0.82mg/ml (3.8mmol/L) with Sodium Ferulate.

Moral hazard in the catastrophic disease health insurance has challenged the sustainability of med-ical budget funds. This paper studies the health care reimbursement rule to counteract moral hazard. Theoretical a-nalysis shows that in the target to maximize social welfare, the optimal rule is to provide consumers who choose low-cost treatment with subsidies and charge a co-payment to those who choose high-cost one. Adopting simulation ap-proach shows that this difference with respect to single reimbursement rules, healthcare expenses and medical insur-ance premiums will be significantly reduced compared to a unified co-payment ratio. This paper also selects the sensitivity test simulation parameters and the results show that different values will not change the herein disclosed mechanism results.
