Objective: To study the effects of static tensile strai n on the secretion of prostaglandin E 2 (PGE 2) of human periodontal ligament fibroblasts (PLFs). Methods: Human PLFs were treated by tensile strain values of 0%,8%,12%,16% and 20% for 24, 48 and 72 h respecti vely with a self-devised loading apparatus in vitro. All samples were rando mly allocated into 15 groups and there were 3 in each group. After treatment cu lture media of the samples were collected and the content of PGE 2 in each medi um sample was determined using RIA ELISA. The data analysis was carried out with SPSS using Dunnett test. Results: In group of 0% the sec retion of PGE 2 by PLFs per day had no relation with loading time; E 2 secre tion increased with the increace of loading time and with the tensile strain va lue in the group of 8%,12% and 16%(P

Objective:To analyze the risk and prognostic of patients with stage ⅠB1 cervical adenocar-cinoma.Methods:The clinical data of 139 patients with stage ⅠB1 cervical adenocarcinoma treated at Department of Gynecology and Obstetrics in Peking University First Hospital from August 1994 to April 2015 were retrospectively reviewed,which included 38 cases of cervical adenocarcinoma and 101 cases of cervical squamous cell carcinoma.A comparison was made between ovarian preserving group and bilateral oophorectomy group,in order to justify the risk and prognosis of ovarian preserving patients.Results:The 5-year cumulative survival rate of stage ⅠB1 cervical adenocarcinoma and squamous cell carcinoma were 89.1% and 92.9% respectively with significant difference (P =0.034).One ovarian metastasis case was observed among the 32 cervical adenocarcinoma patients of bilateral oophorectomy,while another ovarian metastasis case was observed among 54 cervical squamous cell carcinoma patients of bila-teral oophorectomy.The ovarian metastasis rate was 3.1% (1 /32)and 1.8 % (1 /54)respectively with no statistical difference (P =0.574).The cumulative 5-year survival of 6 ovarian preserving patients with cervical adenocarcinoma was 80.1%,while that of 47 ovarian preserving patients with cervical squa-mous cell carcinoma was 94.6% (P =0.127).There was no statistical difference between the survival curve of the two groups.Conclusion:The prognosis of stageⅠB1 cervical adenocarcinomas was somewhat poorer than that of cervical squamous cell carcinoma.However it was still reasonable to perform ovarian preservation among young patients of stageⅠB1 cervical adenocarcinoma with no high risk factors.

[Objective]To evaluate the effect of transverse arch reconstruction by modified Youngswick osteotomy on young and middle-aged hallux valgus. [Methods]From November 2005 to November 2008,25 female(36 feet) hallux valgus patients with the average age of 37.7years old(range 22 to 49 years old) were treated surgically.All feet had hypemobility of the first tarsometatarsal joint and collapse of the transverse arch of the foot.In the operation,the first metatarsal head was pushed laterally,downward and rotated downward.Modified McBride procedure was used on the correction for hallux valgus deformity.The X-ray films of all patients were obtained before operation,and 12 months after operation.The hallus valgus angle and intertatarsal angle were measured and analyzed on radiographs.The surgical outcome was evaluated combined with the Gu Xiang-jie's score.All pamameters were statistically analyzed.All cases were followed-up regularly.[Results]Twenty-one cases(28 feet) were followed-up for averaged 15.9 month.Hallax valgus angle reduced from 26.8??1.07? to 11.1??0.29?,intertatarsal angle reduced from 14.9??1.36? preoperatively to 8.3??1.19? postoperatively.The painful callus beneath the forefoot was alleviated or diminished obviously in all cases.Based on Gu Xiangjie'score,the subjective assessments were given as excellent in 16 feet,good in 7 feet,and fair in 5 feet.The good to excellent result was 82.1%.[Conclusion]For the hallux valgus with hypermobility of the first tarsometatarsal joint and transversal arch collapse,modified Youngswick surgery can recover the transverse arch,correct first metatarsal adduct abnormality,and regain the weight-bearing function of the first metatarsal head.Modified Youngswick surgery is an ideal choice for young and middle-aged hallux valgus because of less complications and reliable surgery outcomes.

? AlM: To observe the clinical curative effect of intravitreal Bevacizumab injection combined duplex technique in treatment of neovascular glaucoma ( NVG) .
?METHODS:Totally 25 eyes of 25 patients with NVG who underwent intravitreal Bevacizumab injection of 1. 0mg (0. 05mL), after the regression of iris neovascularization, 5 eyes with anterior chamber paracentesis fluid auxiliary controlled intraocular pressure. After 2wk, patients were treated by trabeculectomy and phacomulsification (9 eyes were implanted intraocular lens ) . The changes and complications of intraocular pressure, visual acuity, corneas and neovessels were observed after surgery, and followed up 12mo.
?RESULTS:After injection Bevacizumab in 25 eyes, iris neovascularization of 20 eyes subsided in 3 ~ 5d, and 5 eyes subsided in 7d. After controlling intraocular pressure, count of the corneal endothelial cell were 1 629±226mm2 , and none suffered decompensation of corneal endothelium after two- surgery of trabeculectomy and phacomulsification. After followed up 12mo, intraocular pressure of 20 eyes were controlled in normal range; 2 eyes could control in normal range after treated by a kind of anti-glaucoma medicine and 3 eyes was 34 ~38mmHg after treated by anti- glaucoma medicine. 9 eyes had improved vision after implanted intraocular lens.
?CONCLUSlON:lntravitreal Bevacizumab injection can subside iris and anterior chamber angle neovascularization effectively in a short time and reduce intraocular pressure. lt can also reduce the risk of bleeding during operation or after operation. lntravitreal Bevacizumab injection combined with two- surgery of trabeculectomy and phacomulsification can treat neovascular glaucoma effectively.

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.

To study the kinetics in vivo of a Hantaan virus DNA vaccine, we constructed a fusion DNA vaccine,pEGFP/S, by cloning the S segment of Hantavirus into the vector, pEGFP-C1, which encodes Green fluorescent protein EGFP. In this report, we provide evidence that pEGFP/S was distributed and persistently expressed for more than 60 days in several organs after inoculation. Our findings suggest that the persistent immune responses induced by a Hantaan virus DNA vaccine are likely due to the plasmid pEGFP/S deposited in vivo, which acts as a booster immunization.

Objective To analyze the effects of different age and gender on the efficacy and pharmacokinetics of the target controlled infusion of atracurium besylate on liver dysfunction.Methods 160 case of patients with liver dysfunction and undergoing elective general anesthesia operation were divided into four groups according to their age and gender, 40 cases in each group:group A (age≥65 years old, male), group B (age≥65 years old, female), group C (age<65 years old, male), group D (age<65 years old, female).The patients received one-time double dose ED95 atracurium besylate, pharmacodynamic indexes and pharmacokinetic parameters were compared.Results The four groups of patients with block onset time, block maintenance time, clinical duration of T25%, in vivo role time T95%, muscle relaxation recovery index were compared, the difference was not statistically significant.The preoperative and postoperative 24h, four groups of patients with liver function ( alanine aminotransferase, aspartate aminotransferase, albumin, bilirubin) and renal function ( creatinine, urea nitrogen) were compared, the difference was not statistically significant.There was no significant difference between the four groups in the plasma concentrations of the substance to be measured, the peak time, the area under the curve and the elimination half lives.Conclusion For the patients with liver dysfunction, the target controlled infusion of atracurium besylate in general anesthesia operation, gender and age were not considered.

Objective To research patients with ophthalmologic perioperative information systems, strengthening the information management of nursing work, achieving consensus and sharing of health care information resources, and then to explore the clinical application effects of this ophthalmologic peri- opera-tive information systems. Methods The convenient sampling method was used in the study. The control group was consisted of 1 740 patients in our hospital from January to March 2013 (before the application of ophthalmologic perioperative information systems). The observation group included 2 078 patients of the same hospital (after the application of ophthalmologic perioperative information systems). The control group adopted routine pre- operative information acquisition method, the observation group applied ophthalmologic perioperative information systems, which included input function, reading function and statistical function. The incidence rate of canceled operation and satisfaction were compared between two groups. Results Ophthalmologic peri- operative information systems provided patients with information gathering, query and analysis in different periods. The rate of the canceled operation reduced in the observation group from 3.74% (65/1 740) to 2.69% (56/2 078) in the control group, χ2=3.91, P<0.05. The satisfaction degree increased from 91.84 % (1 598/1 740) in the observation group to 96.78% (2 011/2 078) in the control group, χ2=44.60, P<0.05, the difference was statistically different. The hospitalization days from April to September in 2013 shortened compared with those of the same period in 2012. Conclusions Ophthalmologic peri- operative information systems promotes the scientific and informatization of nursing information, which is worthy of wide clinic application.
