Objective To explore the relationship of thyrotropin receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) in patients with thyroid-associated ophthalmopathy ( TAO), and the role played by TRAb and sICAM-1 in the pathogenesis of TAO. Method Twenty-three TAO patients were assigned to groups according to the clinical activity score and EUGOGO. All patients were treated with intravenous methylprednisolone pulse. The levels of serum TRAb and sICAM-1 were evaluated by a competitive radioimmunoassay and enzyme-linked immunosorbent assay respectively before treatment and by the end of each methylprednisolone pulse. Results The differernce in serum TRAb levels was associated with activity scores of TAO (P=0. 020). The change in serum sICAM-1 was associated with durations of TAO ( P = 0.015). During methylprednisolone treatment in active TAO patients, the levels of TRAb kept on decreasing gradually and markedly declined after the third methylprednisolone pulse in active TAO patients (P＜0.05). The trends of changes in serum TRAb and sICAM-1 levels were both different in active and inactive TAO patients by tendency analysis. Conclusion TRAb level was related to the activity of TAO and might serve as a significant predictor of response to methylprednisolone therapy. The negative correlation between sICAM-1 levels and duration of TAO corroborates the role played by ICAM-1 during the early stage of TAO. Higher sICAM-1 levels are not expected to be specific to TAO and may not predict a response to methylprednisolone therapy.

Objective To observe the effect of Dezocine in preventing the adverse reactions during the operation of cesarean delivery.Methods We selected 60 pregnant women in the ASA level Ⅰ who were going to undergo the operation of cesarean delivery.Then we divided them into two groups in random:group A (studying group) and group B (control group),each group had 30 patients.After the fetus were delivered,the patients in group A were given intravenous injection of 1mg of dezocine,and the patients in group B were only given 1 ml saline.Then we observe the heart rate (HR),systolic blood pressure (SBP) and the degree of blood oxygen saturation (SpO2) in seven time points,and analyzed the incidence of contraction pains,chills,nausea and vomiting during the operation in both groups.The time points were when patients entered the operation room (T0),the level of anesthesia was established (T1),5 minutes after fetus were delivered (T2),10 minutes after fetus were delivered (T3),15 minutes after fetus were delivered (T4),30 minutes after fetus were delivered (T5) and the end of operation (T6).Results Compared with group A,the SBP at T2,T3 and T4 were obviously higher than those in group B (P＜0.05).And the HR increased at T2 to T6 in control group (P＜0.05) as compared with group A.The incidence of contraction pains were milder in group A than group B (P＜0.05).In group A,the incidence of chills was13.3％,and in group B,the rate was 30％.Conclusion Dezocine can prevent the adverse reactions during the operation of cesarean delivery.

Objective To evaluate the safety of dynamic anterior plate fixation for cervical distractive flexion injuries and compare its rigidity between different types of plate design. Methods Twelve sets of cadaveric calf spine were used in this test. All the specimens were made into distractive flexion injury models (C4-C5) ac- cording to Allen's method. After discectomy and grafting, they were randomized into three groups in which Orion, Codman, and Window instrumentations were used respectively. The stiffness of each construct was tested in flexion, extension, lateral bending and axial torsion conditions sequentially. Results Compared with an intact cervical spine, the range of motion (ROM) of an injured cervical spine increased whatever plate was applied. Orion in- strumentation presented stiffness the closest to that of the normal control, except for less torsional stiffness. Codman instrumentation provided stiffness close to that for normal and Orion groups only in lateral bending. Window's was the weakest mad not enough in all kinds of movement. Conclusions Static anterior fixation is the first choice for cervical injuries. Dynamic plate fixation may sacrifice stiffness to some extent, especially when a shifting kind of design is to be chosen.

Objective To explore the expression of c-Fos protein and character of mossy fiber sprouting(MFS) in hippocampus of rat with febrile seizures(FS).Methods Thirty-six 21-day-old male Sprague-Dawley rats were randomly divided into FS group,febrile control(FG) group and normal control(NG) group.FS was established by hyperthermal bath.Immune histochemistry and(Timm′s) staining were used to examine the expression of c-Fos protein in CA1 region and MFS in CA3 region of hippocampus.Results Excessive expression of c-Fos protein presented in the hippocampal CA1 region of FS group.The surface area percentage of c-Fos protein of FS group[(2.26?0.23)%] was higher than that of FG group[(1.08?0.19)%] and NG group[(0.71?0.14)%],there were significant difference between FS group and the other two groups(?~2=10.48 P

Nitrobenzene is one of the toxic compounds. Much work had focused on biodegradation of it sofar. Two main pathways for nitrobenzene biodegradation, oxidative and partial reductive pathways, were reviewed in this article. The mechanism of these pathways including involved enzymes and genes was introduce in details. Comparative analysis of the pathways would provide basis for the development and application of biodegradation technology for nitrobenzene and other organic pollutants.

Objective Overexpressions of epidermal growth factor(EGF)and EGF receptor have been associ- ated with progression and invasive phenotype of pancreatic cancer.However,the underlying molecular mechanism by which EGF worked in pancreatic cancer cells has not been completely understood.In this study,effect of EGF on the invasion and metastasis of pancreatic cancer cells and its regulatory mechanism were investigated.Methods The effects of EGF on the proliferation,adhesion and invasion of pancreatic cancer cells were detected by WST-1 prolif- eration assay,adhesion assay and invasive assay,respectively.The activity and expression of MMP-2 and MMP-9 were examined by zymography,Western blot and RT-PCR,respectively.The activity of NF-?B was examined by EMSA.Results EGF could significantly promote the invasiveness of pancreatic cancer cells but did not affect cell proliferation or adhesion.The expressions of NF-?B and MMP-9 were significantly increased by EGF,but EGF did not affect the activity and expression of MMP-2.Furthermore,EGF stimulated the NF-?B binding activity.Pre- treatment with NF-?B inhibitors,pyrrolidine dithiocarbamate(PDTC),could significantly inhibit the activity of NF-?B induced by EGF.Meanwhile,the EGF-induced expression and activity of MMP-9,as well as cell invasiveness were also inhibited by NF-?B inhibitor.Conclusion EGF could increase the expression and promote the invasiveness of MMP-9 via the activation of NF-?B in pancreatic cancer cells,which implies that NF-?B inhibitant,such as PDTC,may diminish the invasiveness of pancreatic cancer cells.

Objective To analyze the correlation factors between CT imaging features of pulmonary embolism(PE)and clinical severity stratification,to explore the value of CT pulmonary angiography (CTPA)in acute PE severity stratification.Methods According to the clinical severity,48 patients with acute PE proved by CTPA were classified into two groups,including 21 critical and 27 non-critical patients. Embolism index,ratio of central pulmonary involvement,ratio of right ventricle maximum minor axis (RVMMA)to left ventricle maximum minor axis(LVMMA),namely RV:LV,dilation of main pulmonary and/or right pulmonary trunk,and dilation of bronchial arteries in both groups were analyzed comparatively. The correlation factors between CT imaging features and PE clinical severity stratification were explored.The correlation between RV:LV and embolism index of 48 patients was analyzed.Results Pulmonary embolism index(22.0%—85.0%,median 38.0%),ratio of central pulmonary involvement(42.5%),RV:LV (0.90—1.90,median 1.30),dilation of pulmonary artery(14 cases),and dilation of bronchial artery (8 cases)in critical group(21 cases)were higher than those corresponding factors(5%—48%,median 21.5%,31.25%,0.80—1.40,median 1.00,5 eases,and 3 eases)in non-critical group(27 cases) (Z=4.27,X~2=5.40,Z=2.58,X~2=11.45,X~2=4.87,P

Objective To study the expression of vascular endothelial growth factor(VEGF)-C, VEGF-D and their receptor-3(VEGFR-3)in patients with colorectal cancer and their clinicopathological value.Methods Eighty specimens of the colorectal cancer and thirty normal adjacent bowels were stud- ied.The expression of VEGF-C,VEGF-D and VEGFR-3 proteins and mRNAs in specimens of colorectal cancers and normal colorectal tissues was studied by Strept-avidin-biotin complex method and RT-PCR. Clinicopathological data and survival of each patient were recorded and analyzed.Results①The staining of brown or filemot in cytoplast were observed as the positive expression of VEGF-C,VEGF-D and VEGFR-3 proteins.The positive rate(48.8%,56.3%,38.8%)and mean value(1.09?1.20,1.13?1.09,0.90?1.19)of VEGF-C,VEGF-D,VEGFR-3 expressions in specimens of colorectal cancer were significantly higher than those of the normal bowel tissues(P＜0.05).The expression of VEGF- C,VEGF-D and VEGFR-3 mRNAs by RT-PCR was correlated with that of VEGF-C,VEGF-D and VEGFR-3 proteins in colorectal carcinomas and normal bowel tissues.②Significant correlation between VEGF-C(P=0.0069),VEGF-D(P=0.0024)and VEGFR-3 expression was observed in colorectal cancers;moreover,no correlation between VEGF-C and VEGF-D.③The expression of VEGF-C, VEGF-D and VEGFR-3 in colorectal cancers was not correlated with age,gender,site and dimension of lesion,types of gross and histological,degree of differentiation and liver and pulmonary metastasis,but correlated significantly with Dukes' stage(P=0.0234,P=0.0003,P=0.0429)and lymph node me tastasis(P=0.0059,P＜0.01,P=0.0068).The increased death rate(P=0.0374,P=0.0127) and poor survival(P＜0.01,P＜0.01)were observed in the colorectal cancer patients with positive ex- pression of VEGF-C and VEGFR-3 when comparing with the patients of the negative expressions,but the expression of VEGF-D in colorectal cancers was not correlated with prognosis of the patients.Con- clusions Colorectal cancer cells may secrete lymphangiogenetic growth factors VEGF-C,VEGF-D and their receptor VEGFR-3,which induce the growth of lymphatic vessel endothelium and lymphangiogene- sis by VEGF-C,VEGF-D/VEGFR-3 signaling pathway,further accelerate lymphatic metastasis of colo- rectal cancers.VEGF-C,VEGF-D and VEGFR-3 might be acted as molecular phenotypes of lym- phangiogenesis in coiorectal cancers and important markers for evaluating lymphatic metastasis and prog- nosis in patients with coloreetaI carcinoma.

Objective To explore the effect of timeliness motivation theory-based continuing care on the self-care ability and healthy behavior in elderly patients with type 2 diabetes. Methods A total of 202 elderly patients with type 2 diabetes in our hospital were selected,and were randomly divided into observation group and control group according to the random number table, with 101 cases in each group. The control group were given healthy related education during hospitalization , and post-discharge telephone follow-up every month, lasting 10~15min each time.The observation group were additionally given timeliness motivation theory-based continuing care by telephone follow-up each month , including emotional arousal , need motivation , examples stimulating and benefit motivation, lasting 6 months. Their self-care ability and healthy behavior in the two groups were compared. Result The self-care ability in the observation group was significantly significantly better than that of the control group (P<0.001), and had significantly much more healthy behaviors than the latter (P < 0.001). Conclusion Timeliness motivation theory-based continuing care can improve the self-care ability and healthy behavior in elderly patients with type 2 diabetes.
