Captopril (CPT, 40, 80mg/kg, ig) enhanced serum superoxide dismutaseactivity, and suppressed luminal-dependent chemiluminescence of peritoneal macrophagesin mice. CPT (160mg/kg, ig) had a suppressive action on lipid peroxidation of mice. Theseresults suggested that CPT had antioxygen free radical effect or anti-lipid peroxidationeffects. CPT at 25 ?g/ml concentration suppressed ConA-induced prolifeation of mousesplenic T lymphocytes in vitro, which suggested that CPT had a suppressive effct on Tlymphocyte function.

Objective To assess the efficacy of ultrasound contrast agent Levovist in evaluating vascularization of ovarian tumors.Methods Nineteen ovarian lesions (seven benign ovarian tumors,twelve malignant ovarian tumors) were submitted to color Doppler flow imaging (CDFI) before and after i.v.Levovist for examining their vascularization,including the number of blood vessel,vessel torsion and Doppler signal enhancement. And then receiver operator characteristic(ROC) curves were established.Results Compared to benign tumors',after contrast color Doppler signals in malignant tumors enhanced obviously and character characteristic vessel morphologies were observed.Vessel numbers and tortuosity increased obviously.Doppler signal enhancement appeared earlier,arrival to peak enhancement was quicker,and duration longer.ROC showed time to commencement for the enhancement ≤50 s,time to peak ≤100 s and enhancement duration ≥400 s,at which the sensitivity and specificity were the highest.Conclusions Levovist,as a contrast agent, increases the intensity of color Doppler signals obviously,and allows a more complete display of the vascular patterns of ovarian tumor.It improves markedly the role of CDFI in the diagnosis and differentiation of ovarian tumors.

There was significant difference between transfection group and negative control group ( P ＜ 0. 01 ), whereas there was no significant difference between negative control group and blank control group ( P ＞ 0. 05 ). The efficiencies of down-regulated of HLA-G were (81. 1 ± 14.4)%, ( 18.0 ± 7.7)%, 0 in transfection group, negative control group and blank control group respectively. ( 3 ) The invasive number of transfection group, negative control group and blank control group were 57 ± 38,364 ± 79 and 260 ± 84, respectively, with a significant difference between transfection group and negative control group (P ＜ 0. 01 ). There was no significant difference between negative control group and blank control group ( P ＞ 0. 05 ). ( 4 ) The p-p38MAPK/p38MAPK values of the HLA-G transfection group, negative control group and blank control group were 0. 74 ±0.04, 0. 47 ± 0. 09 and 0. 36 ± 0. 21, respectively. HLA-G transfection group was significantly different compared with the other two groups( P ＜0. 01 ). (5)Without or with SB203580, the p-p38MAPK/ p38MAPK values of the HLA-G transfection group were 0. 89 ± 0. 09 and 0. 16 ± 0. 04, the values of negative control group and blank control group were 0.76 ±0.08, 0. 14 ±0.03 and 0.51 ±0.05, 0.03 ±0.01, respectively.

(6)Without or with SB203580, the invasive number of transfection group were 51 ± 13 and 90 ± 21 ,respectively,which was significantly different ( P ＜ 0. 01 ). The invasive number of negative control group and blank control group were 290 ± 52, 298 ± 33 and 290 ± 73, 264 ± 64, respeczively, which was no significant difference between without SB203580 and with SB203580 (P ＞ 0. 05 ). Conclusions HLA-G gene may regulate invasion of trophoblast-derived cell line HTR-8/SVneo via p38MAPK signaling pathway. The lower expression of HLA-G in trophoblast cells may lead to the occurrence of pathologic pregnancy.

Objective To establish a stable animal model for sequentially dynamic and direct monitoring of the skin wound infection. Methods The mice with full-thickness skin incisions were replicated. After immediate subcutaneous suture,the mice were randomly divided into four groups,ie,Group A was inoculated with 50 μl sterile PBS solution),Groups B,C and D were inoculated with 50 μl suspension containing 1 × 106,1 × 108 and 1 × 1010 colony forming unit (CFU)/ml bioluminescent methicillin-resistant staphylococcus aureus (MRSA) respectively.Then,the diet behavior of each group was observed and the mean weight and mortality of each group were also recorded at different time points.The bioluminescent intensity of fluoresce in the wounds was recorded at different time points by using the charge-coupled device (CCD) based imaging system.Local wound tissues were incised at 24 hours after inoculation for HE staining so as to observe wound inflammatory reaction in each group.Wound healing time of each group was also recorded. Results ( 1 ) Average weight:Groups A and B showed unobvious changes in weight; Group C lightened until day 3 after inoculation and then recovered gradually to the preinoculation level at day 14; Group D lightened gradually until death.(2)Mortality:Groups A and B had no death; Group C had 10％ deaths at day 14; Group D had 100％ deaths.(3) Bioluminescent intensity of wounds:Groups A and B showed a gradual weakened luminescence since the day of inoculation and had almost complete disappearance at days 5 and 7 respectively; there was no sign of obvious increase or decrease in Group C from the day of inoculation till day 14 ; Group D had a gradual increase since the day of inoculation and the luminous area expanded until the death.(4) HE staining at 24 hours after inoculation:all the four groups showed inflammatory cell infiltration,especially in Groups C and D.(5) Wound healing time:wound healed at days 5 and 7 after inoculation in Groups A and B; the wounds showed no healing even at day 14 in the Group C,but the wounds length and area did not show obvious enlargement or diminishment ; the wounds extended gradually until the death in the Group D,since the day of inoculation. Conclusions The inoculation of 50 μl suspension with 1 × 108 CFU/ml bioluminescent MRSA to full-thickness skin incision rats allows direct,real-time dynamic and continuous detection of the occurrence and development of the wound infections.The infection model is easy to make and has stability and high repeatability.

ObjectiveTo observe production of vascular endothelial growth factor (VEGF) induced by granulocyte/macrophage colony-stimulating factor (GMCSF)via ERK nerve growth factor (NF)-κB singling pathway in human fibroblasts during wound healing and explore relating mechanism.MethodsHuman fibroblasts from the injured skin were used for this study and treated with GMCSF.RT-PCR was used for analyzing the protein and mRNA levels of VEGF and Western blotting was employed to determine the phosphorylation of ERK. The fibroblasts were pre-treated with ERK specific inhibitor PD98059 and further treated with GMCSF, then the fibroblasts and the supernatant were collected for detection of protein level of VEGF by means of Western blot. ERK signal pathway was inhibited to detect the activation of NF-κB by means of immunofluorescence staining. Furthermore, the nuclear and cytoplasmic extraction kit was used to separate the cytoplasm and nucleus and Western blot employed for observation of the NF-κB activation. ResultsThe mRNA level and protein level of VEGF were increased significantly with treatment with higher concentration of GMCSF in a dose-dependent manner. VEGF mRNA level was increased two hours after administration with GMCSF and reached peak at 4-6 hours. GMCSF could remarkably activate the ERK phosphorylation. Compared with GMCSF, the ERK specific inhibitor PD98059inhibited significantly the effect of GMCSF in inducing VEGF expression (P ＜ 0.05). Western blot and immunofluorescence staining analyses showed that the activation of NF-ΚB was inhibited with reduced production of VEGF after GMCSF treatment.Conclusion GMCSF up-regulates production of VEGF through activating NF-κB via ERK signal pathway in the human fibroblasts.

ObjectiveTo develop a new sutureless technique (photochemical tissue bonding,PTB ) for repair of corneal perforation. Methods A total of 60 rabbits were used for creating corneal perforation models.The corneal perforation on the left eye was repaired by sutures and the injury on the right eye was fixed with the use of amniotic membrane with PTB.The outcomes of the two mentioned repair methods were compared by observing the leakage of aqueous and the morphology of the anterior chamber at different instants,measuring the intraocular pressure (IOP) and observing the formation of neo-vessels and scars of cornea in the use of histological analysis. Results There was no leakage of aqueous and no difference for morphology evaluation in both treatments.PTB could adhere AM on the cornea to restore the corneal perforation.The peak IOP in the PTB treatment group at days 0,7 and 14 postoperative [ (531.2 ±49.5) mm Hg,(542.6 ±74.8) mm Hg and (603.9 ±69.1) mm Hg,respectively] was significantly higher than that in the suture group at the same instants [ (41.3 ±12.7) mm Hg,(142.6 ±25.4) mm Hg and (333.3 ± 66.7) mm Hg,respectively] (P ＜0.O1 ).Compared with suture repair,the treatment with PTB resulted in a better outcome of wound healing with less neo-vessels and less scars of cornea. Conclusion PTB treatment for repair of corneal perforation is superior to suture repair.

Objective To summarize the experience of multidisciplinary consultation for prenatal fetal deformity, and to explore the mode suitable for China. Methods The Obstetrics and Gynecology Hospital of Fudan University and Children's Hospital of Fudan University established a joint multidisciplinary consultation center, including obstetrics, pediatrics, pediatric surgery, ultrasound and other departments. A total of 3 378 pregnant women visited the consultation center from July 31, 2003 to August 1, 2013. After consultation, treatment was divided into three classes:pregnancy termination, pregnancy continuation and perinatal treatment. Follow-up was made through correspondence and telephone communication. Retrospective analysis on reasons for consultation, fetal structural abnormalities of the classification system, chronological order of abnormalities, gestational weeks of diagnosis, maternal-related factors, treatment and prognosis was performed. Results (1) Reasons for consultation:Among 3 378 women undertaking prenatal multidisciplinary consultation, 3 243 (96.00%) were due to fetal factors, and 135 (4.00%) were due to maternal factors. (2) Classification of fetal structural abnormalities:Among the 3 243 cases undertaking consultation with fetal factors, fetal abnormality was found in 80.85%(2 622/3 243). The most common were neurological abnormalities(23.19%, 608/2 622), followed by urinary tract malformation (20.25%, 531/2 622) and cardiovascular malformation (15.48%, 406/2 622). These were followed by digestive system malformation, limb deformities and space-occupying lesions. There were 156 cases of multiple malformations. (3) Average gestational weeks for diagnosis of fetal deformity:The 2 622 cases of fetal deformity were diagnosed at a mean (26.7± 2.1) of gestational weeks (21.1–30.4 weeks). Urinary tract malformations were detected at (24.0±0.7) weeks, whereas digestive system malformations were detected at (28.3±2.6) weeks. (4) Induced labor:Induced labor cases accounted for 35.66% (935/2 622), among which, 92 cases were fetal intrauterine death and 843 cases were active choice. The several highest induced labor rates resulted from multiple malformations (75.64%, 118/156), abdominal wall defects (62.22%, 28/45), diaphragmatic hernia (61.54%, 24/39), cleft lip and palate (55.32%, 26/47) and cardiovascular malformations (49.51%, 201/406). For nervous system (27.80%, 169/608), urinary tract (25.80%, 137/531) and digestive system malformations (26.94%, 66/245), induced labor rates were <30%. For abdominal lesions (14.04%, 25/178) and sacrococcygeal teratoma (13.64%, 3/22), induced labor rates were<15%. (5) Continuation of pregnancy in 1 687 cases:Cesarean section was conducted in 1 046(61.94%). Neonatal death occurred in 117(6.94%).(6) Perinatal treatment:Twenty-one cases were treated during pregnancy, including thirteen cases with fetal ascites and hydrothorax treated by drainage, five cases with fetal anemia treated by intrauterine transfusion and three cases with fetal tachycardia treated by digoxin. Ten cases were treated by ex-utero intrapartum treatment. After birth, 297 newborns immediately underwent neonatal surgery. Among these, 259 cases underwent radical surgery, eleven palliative surgery, and sixteen elective surgery after follow-up. Conclusions Prenatal multidisciplinary consultation can make comprehensive multidisciplinary assessment of fetal prognosis and improve the diagnosis and treatment of structural malformations.

Objective To review the clinical treatment and outcome of ultrasonographic soft markers in prenatal diagnostics. Methods This study recruited 268 pregnant women who underwent prenatal diagnostics in our hospital between Jun 2005 to Mar 2009. Fetuses were followed up postnatally. The outcome and chromosomal abnormalities of ultrasonographic soft markers were assessed. Results Of 268 cases consulted, 29 cases were missed (10.8%), 34 cases (12.7%) chose abortion, and 205 cases (76.5%) delivered. The top four most common delivered isolated markers were thickened nuchal fold, mild pyelectasis, echogenic bowel and rhizomelic limb shortening. Mild ventriculomegals had the highest aborted rate (17.2%). Six chromosomal structural abnormalities and one 21-trisome were detected in 59 fetuses who received chromosomal examination. Conclusions Ultrasonographic soft markers are risks to both fetal trisome and chromosomal structural abnormalities. Owing to extinction in most cases, consultant should be strengthed to avoid unnecessary invasive examination and abortion.

To investigate the clinical efficacy of sorafenib in the treatment of primary hepatic carcinoma (PHC) and its effects on serum vascular endothelial growth factor receptor -2 (VEGFR -2) and placental growth factor (PLGF) levels.Methods A total of 110 patients with a confirmed diagnosis of PHC who received treatment in Jinshan Hospital Affiliated to Fudan University from July 2014 to March 2016 were randomly and equally divided into observation group and control group .The control group was given routine treatment, while the observation group received sorafenib in addition to the routine treatment .Serum levels of VEGFR -2 and PLGF were measured by ELISA.Liver function parameters, aspartate aminotransferase (AST), prothrombin time (PT), total bilirubin (TBil), albumin (Alb), and alanine aminotransferase (ALT), were also recorded.Comparison of continuous data between groups was made by independent samples t -test, and the changes in continuous data after intervention in each group were evaluated by paired samples t -test.Comparison of categorical data between groups was made by chi -square test.Results The observation group showed significant reductions in serum VEGFR -2 and PLGF levels after treatment (VEGFR -2: 7053.2 ±1836.1 ng/L vs 8721.4 ±2427.8 ng/L, t =4.089, P <0.001; PLGF: 468.4 ±136.5 pg/ ml vs 656.8 ±191.4 pg/ml, t =5.975, P <0.001).After treatment, the observation group had significantly lower serum VEGFR -2 and PLGF levels than the control group (VEGFR -2: 7053.2 ±1836.1 ng/L vs 8097.5 ±2325.4 ng/L, t =2.64, P <0.05; PLGF: 468.4 ± 136.5 pg/ml vs 643.3 ±195.8 pg/ml, t =2.48, P <0.05).The observation group showed significant changes in serum AST and ALT lev - els after treatment (t =4.302 and 3.097, both P <0.05).After treatment, the observation group had significantly lower serum AST and ALT levels than the control group (t =2.56 and 2.39, both P <0.05).Compared with the control group, the observation group had better follow -up results, with a significantly increased disease control rate (27.3% vs 47.3% , χ2 =4.705, P =0.030), and had a significantly higher survival rate at 40 months after treatment (43.6% vs 69.1%, χ2 =7.245, P =0.007).Conclusion Sorafenib is effective in the treatment of PHC patients, as it can significantly reduce the serum levels of VEGFR -2 and PLGF, prolong the survival time of patients, and improve the prognosis of patients.
