Objective:To explore the expression of MIP-1? during healing of skin incised wound and the applicability of time-dependent expressions of MIP-1? to determination of wound age. Methods:An incised wound was made in the dorsal skin of mouse. Immunohistochemical and image-analysis techniques were employed in vital skin wounds 1h~14d after incision and postmortem incision 0.5~6h after death, and the non-incised mouse skin was used as contro1.Results:In the vital skin incisions,expression of MIP-1? began at 6h after incision,which increased subsequently,and peaked at 3d.The quantity of MIP-1?expression decreased and minimized in the specimens aged 14 days. In the non-wounded groups and postmortem incision groups MIP-1? was only detected as weak expression in the epidermic cells,sweat gland cells and endothelial cells. Conclusion:The time-dependent expression of MIP-1?during healing of skin incised wound may be used as a useful reference marker.

Finite element is a common means to study pelvic biomechanics. This article introduces current methods to establish finite element model and application advances of the models in pelvis,and explores issues and future developing direction of pelvic finite element models.

Objective The purpose of this study was to investigate the relationship of p185 and p53 protein overexpression with pathological types and recurrence.Antibodies against p185 and p53 proteins were used to measure expression of these proteins in the nuclei or cell membrane of cells from sections of the giant cell tumor of bone GCT.It showed that 11 out of 52 tumors overexpressed p185 protein and 14 out of 52 tumors had abnormally high levels of p53 protein,4 cases had abnormally high levels of both p185 and p53 proteins,positive expression rates of p185 and p53 in cases with recurrence and cases without reccarrence were 46 2%,20 5% and 38 5%,15 4% respectively.However,there was no association between p185 and p53-positive cases and pathological degree.There was significant correlation between the expression of p185 and p53 protein in the giant cell tumor of bone and recurrence.(? 2=6 125,P=0 047).However,there was no statitically significance between the expression of p185 and p53 protein in the giant cell tumor of bone and pathological types.So that,we consider that the clinical significance for p185,p53 overexpression in GCT to be researched further.

Objective To explore the targeted nursing care for patients with severe traumatic brain injury complicated with intracranial infection. Methods 35 patients of severe traumatic brain injury complicated with intracranial infection from January, 2009 to December, 2011 were reviewed. Results There were 10 cases cured, 12 cases improved very well, 4 cases improved, 5 cases invalid and 4 cases died. The total effective rate was 62.86%and the fatality rate was 11.43%. Conclusion Intracranial infection can be controlled effectively by the venous and intrathecal injection of antibiotics and targeted care in the patients with severe traumatic brain injury.

Objective To compare effect of trichosanthin and methotrexate in the treatment of uterine scar pregnancy by a multi-center study. Methods 90 uterine scar pregnancy patients were selected from department of obstetrics and gynecology,in xinyang central hospital,the second affiliated hospital of zhengzhou university,zhumadian central hospital,using random number table divided into 2 groups.The control group of 45 cases were treated by methotrexate,gluteal muscle injection,50 mg one time,and took mifepristone 50 mg,two times a day,a week for a course of treatment;45 cases in the experimental group,were treated with trichosanthin,intramuscular injection of 1.2 mg/time,two times a day,and oral administration of bloven,0.6 g/d,a week for a course of treatment.The end of a course of treatment,2 groups of patients before and after treatment were compared of the serum progesterone level,β-HCG,side reactions after treatment.Results After treatment,progesterone levels were significantly reduced,and the experimental group levels were lower than the control group obviously,the difference has statistical significance(P<0.05).Serum -HCG level after the treatment significantly reduced,and the experimental group in serum -HCG levels were significantly lower,with statistical difference (P <0.05 ). Comparison of adverse reaction of the patients,the experimental group was obviously lower than control group,with statistically significant difference (P<0.05).Conclusion For the treatment of uterine scar pregnancy,trichosanthin and methotrexate have certain effect,but trichosanthin could lower serum progesterone,β-HCG levels more significantly than methotrexate,trichosanthin group side reaction rate is low.

Objective To observe the effect of enhanced extracorporeal counterpulsation (EECP) on intraocular pressure (IOP). Methods 25 patients were measured their IOP bilaterally with Schoitz tonometer before and after EECP. Results The IOP decreased in both left and right eyes after EECP (P<0.01). Conclusion EECP can reduce intraocular pressure.

[Objective]To explore the technique of arthroscopy plus radiotherapy in the treatment of pigmented villonodular synovitis of the knee and to evaluate its clinical value.[Method]A total of 14 cases of pigmented villonodular synovitis of the knee were treated from January 2000 to July 2003.Intra-articular excision under arthroscope with a combined application of routine intrusments and Bipolar radiofrequency was performed on all these 14 cases,and postoperative radiotherapy for diffused pigmented villonodular synovitis of the knee,13 patients were followed up for 10~45 months,and were evaluated for range of motion,pain,swelling effusion.[Result]Thirteen cases according to the International Knee Documentation Committee(IKDC)criteria,subjective knee score was (58.7+6.4) and (86.5 ?5.7) respectively before surgery and at the last follow-up.[Conclusion]In case of pigmented villonodular synovitis of the knee joint,arthroscopical synovectomy can make good surgical results,and postoperative radiotherapy is an effective treatment for diffused pigmented vilionoclular synovitis of the knee.

Objective:To explore the effects of diltiazem on ventricular remodeling and inflammation in rat heart following acute myocardial infarction(AMI).Methods:The model of AMI rats was randomly divided into diltiazem group(D group)and control group(AMI group),besides another group of sham operation(S group).The data of ejection fraction(EF) and the left ventricular mass(LVM)were examined with echocardiography,and leukocyte infiltration in situ was analyzed on the HE staining slices,with the expression of proinflammatory cytokines(IL-I?,IL-6,TNF-?)detected by RT-PCR at 1d,3d,1w,2w and 4w intervals after AMI.Results:The results from echocardiography showed that EF increased(73.7?3.1% vs 61.0?2.6%)and LVM decreased(0.81?0.12g vs 0.92?0.12g),both significantly in D group at 4w,compared with those of the AMI group(P
