ABSTRACT

Objective Rheumatoid arthritis (RA) is a typical type Ⅲ hypersensitivity with a large number of immune complexes (IC) and complement deposits in the synovial tissue , but its specific pathogenesis is not yet clear.This article was to explore the expression of the antigenic profile of serum ICs in RA.Methods ICs were isolated from the serum of 55 patients with RA (41 cases of anti-CCP antibody [+] and 14 cases of anti-CCP antibody [-]), 41 with systemic lupus erythematosus (SLE), and another 41 healthy controls by polyethylene glycol (PEG) precipitation, separated by immunoprecipitation, digested with trypsin in gel, and then subjected to mass spectrometry for identification.The levels of total proteins were compared among different groups using Vennny 2.1.0.The protein expression was considered to be up-regulated when the total protein level of the RA group was >2 times and down-regulated when it was <0.5 times that of the control.Further functional analysis was performed on the differential proteins in RA using the STRING software.Results Totally, 277 proteins were identified in the serum ICs of the RA patients, including 162 in the anti-CCP (+) and 248 in the anti-CCP (-) RA group.Compared with the SLE and healthy control groups, only 129 proteins were found in the RA patients, including 38 in the anti-CCP (+), 109 in the anti-CCP (-) RA group, and 18 in both the two groups.Among the proteins identified in the RA patients and healthy controls, 2 and 11 were up-regulated while 17 and 21 down-regulated in the anti-CCP (+) and anti-CCP (-) RA group, respectively.Conclusion More differentially expressed proteins were identified in the anti-CCP (-) than in the anti-CCP (+) RA patients.The identification of differentially expressed proteins provides a new idea and direction for the investigation of the pathogenesis and new biomarkers of RA.

ABSTRACT

Objective The inhibitor of differentiation 3 (Id3) is an important transcriptional regulation factor, which participates in tumorigenesis, cell proliferation, and cell apoptosis.β-catenin, as a central molecule of the Wnt signaling pathway, is critical for tumor development.This study aimed to evaluate the expressions of these two molecules and the regulatory effect of Id3 on β-catenin in different tumor cells.Methods Total RNA was extracted using the Trizol Reagent.The relative mRNA expression levels of Id3 and β-catenin in tumor cells were detected by quantitative real-timePCR(qRT-PCR).The recombinant eukaryotic expression vector pEGFP/Id3 with the human Id3 gene was transfected into A549, A549/ DDP and SW-480 cells using the non-liposome-mediated method.The protein expressions of Id3 and β-catenin were determined by Western blot.Results The expression of Id3 was significantly lower in the colorectal cancer cell lines SW-480 and HT-29 than in A549 and other tumor cells (P0.05).Western blot showed the same results.Conclusion The expression levels of Id3 and β-catenin vary in different tumor cell lines.Anabnormally high level of β-catenin is an important risk factor for colorectal cancer, and the down-regulatedexpression of β-catenin after eogenous transfection of Id3 may provide some new ideas for target gene therapies of colorectal cancer.

ABSTRACT

Objective To explore the changes of plasma level of adrenomedullin(ADM)in congenital heart disease patients with heart failure,analyze the relationship between ADM and the severity of heart failure, assess the value of plasma ADM in the diagnosis of CHF and evaluate the cardiac function in pediatric patients with congenital heart disease. Methods 46 patients with CHD were enrolled according to the modified Ross Score. They were divided into three groups:mild CHF group(n = 16)and moderate CHF group(n = 18)and severe CHF group(n = 12). 25 matched normal children were enrolled as controls. Plasma ADM was measured with radioimmunoassay(RIA)and the contents of NT-proBNP were determined among all the patients. LVEF and E/A in all of them were also detected. The relationship between plasma ADM level and modified Ross Score and echocardiographic cardiac functional indexes was analyzed. Results Plasma ADM was positively correlated with modified Ross Score(r = 0.65,P < 0.01). Plasma ADM concentration in the severe CHF group was significantly higher than that of mild and moderate CHF group(P < 0.01),and plasma ADM concentration in the mild CHF group was higher than that in the control group(P<0.05).Plasma ADM was negatively correlated with LVEF and E/A(r =-1.05,P < 0.01). Conclusion Plasma ADM level could be used to assess cardiac function and diag-nose CHF with CHD.

ABSTRACT

Background and purpose:Hepatic epithelioid hemangioendothelioma (HEHE) is an extremely rare, vascularly original tumor, and would be misdiagnosed easily in the clinical and imaging characteristics. This study aimed to investigate the imaging features of HEHE and our experience in clinical diagnosis and treatment, and to provide important reference for the diagnosis and treatment of HEHE in the future.Methods:This study retrospectively analyzed clinical manifestations, imaging features, pathological characteristics and treatment effects of 5 HEHE cases confirmed by pathology at Department of Integrative Cancer, Fudan University Shanghai Cancer Center.Results:The ratio of male to female patients was 2 to 3. HEHE predominantly occurred in middle-aged female patients whose ages range from 26 to 65 (mean=45.6). Imaging features of HEHE included multifocal hepatic disease (n=2), systemic multi-center multi-tissue occurrence (n=3). The ultrasound images showed isoechoic or hypoechoic lesions with no obvious blood lfow signal in the lesions. CT plain scan showed isointensity or hypointensity, while MR unenhanced with hypointense T1 signal and hyperintense T2 signal. The density or signal was uneven. Contrast-enhanced CT and MR images showed “slow in slow out”, obvious and variable degrees of peripheral rim enhancement. High FDG uptake showed delayed imaging characteristics (PET/CT). DSA angiography showed the tumor blood vessels were slim. After transcatheter arterial chemoembolization (TACE) surgery, lipiodol deposition within the lesion was not ideal. Under the microscope, tumor cells showed epithelial differentiation; angiogenesis was also visible. Immunohistochemistry staining showed CD31 and CD34 positive in all the 5 cases. Two cases treated with TACE combined with high intensity focused ultrasound (HIFU) and/or radiofrequency ablation (RFA) had good result.Conclusion:The clinical and radio-logical characteristics of HEHE are distinctive. Currently, for patients with systemic multi-organizational multi-center lesions, TACE combined with HIFU and/or RFA might be the most effective treatment method.

ABSTRACT

@#Promoting uric acid excretion is an important approach for the treatment of gout and hyperuricemia. There are two main approaches included in the mechanism: one is inhibiting the function of renal tubular uric acid transporter to reduce the absorption of uric acid, and promoting excretion; the other is using uricase to catalyze the oxidation of uric acid to a more water-soluble allantoin that can also increase excretion. The mechanisms and progress of the uricosuric drugs are reviewed in this paper, providing reference for the further research and development.

ABSTRACT

Objective To evaluate effects of maternal hypothermic cardiopulmonary bypass on fetal homodynamic and carbohydrate metabolism. Methods Twenty pregnant sheep were divided into four groups randomly: control group(n=5),normothermic group (35-36℃)(n=5), mild hypothermic group(32-34℃)(n=5) and moderate hypothermic group (28-31℃)(n=5).Thoracotomy was performed without CPB in the control group. Routine CPB was established with different temperature in other three groups. The temperature of normothermic group was kept normal; the left two groups were cooled down to the set point of temperature and then rewarmed back to normal level. Fetal and maternal temperatures, heart rate,mean blood pressure(BP), pulse index (PI) of fetal umbilical artery (UA) and internal carotid artery (CA) were evaluated at cooling and rewarming stages. Biochemical indicators including blood glucose and lactic acid were also measured at the same time. Results There are no differences in mesn BP of ewas and fetal lambs between the different groups (P>0.05). CA PI value of mild hypothermic group and moderate hypothermic group were significantly higher than those of control group and normothermic group (P<0.05). There was no difference of UA PI in the four groups, but PI increased following the prolonged duration of CPB. There was no difference change of blood glucose in the four group of fetus, which was significantly lower than the ewe groups. An upward trend of fetal blood lactic acid with time was observed in three CPB groups. The whole level of fetal blood lactic acid was much higher than that of maternal blood of lactic acid. Conclusion Cooling of maternal bypsss decreases fetal heart rate significantly,and fetal heart rate recovered to base line following rewarming phase. There was no signicant effect of CPB on fetal mean BP. However, CPB impacted on the blood flow of fetal brain and umbilical artey. Hypothermia CPB can increase fetal blood glucose and blood lactic acid dramatically.

ABSTRACT

BACKGROUND: Our former studies have shown that bone marrow mesenchymal stem cells (BMMSCs) can be induced differentiation to vascular smooth muscle-like cells (VSMLCs) and vascular endothelium-like cells (VELCs), which are compatible with collagen-embedded polyglycolic acid scaffolds. OBJECTIVE: To investigate the possibility of constructing small diameter tissue-engineered blood vessels via subcutaneous implantation. METHODS: The cells-scaffold complex was produced by separately seeding VSMLCs and VELCs derived from BMMSCs on polyglycolic acid collagen scaffolds. The two layers were separated by ECMgel. The cells-scaffold complex was subcutaneous implanted into small diameter tissue-engineered blood vessels.RESULTS AND CONCLUSION: Histological analysis of the small diameter tissue-engineered blood vessel walls revealed a typical artery structure, which was similar to natural vessels. The tissue-engineered blood vessels were not broken down under a force of 26.6 kPa. Eight weeks after implantation, the Brdu-labeled seed cells were found in the three layers of the vessel walls. The results revealed that the subcutaneous tissue was a good bioreactor to construct small diameter tissue-engineered blood vessels.

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>Serum tumor markers play important roles in diagnosis, response and prognosis monitoring for lung cancer. The clinical significance of serum level of tissue polypeptide specific antigen (TPS) was investigated in diagnosis, response monitoring and prognosis in patients with lung cancer, compared with carcinoembryonic antigen (CEA), precursor of gastrin-releasing peptide (Pro-GRP) and cytokeratin-19-fragments (CYFRA21-1).</p><p><b>METHODS</b>Blood samples of eighty-two patients with lung cancer before treatment and some after chemotherapy were measured by ELISA for four tumor markers.</p><p><b>RESULTS</b>Compared with lung benign diseases group and health control group, the positive rates and levels of TPS, CEA and Pro-GRP in patients with lung cancer were higher, with statistically significant difference. TPS in extensive-small cell lung cancer was significant higher than that in limited-small cell lung cancer. The positive rates and levels of TPS, CEA and Pro-GRP in patients after treatment had significant decreases compared with before treatment. TPS was an independent prognostic factor of non-small cell lung cancer.</p><p><b>CONCLUSION</b>TPS is valuable to diagnosis, response monitoring for patients with lung cancer, moreover, it maybe a useful factor of prognosis of non-small cell lung cancer.</p>

ABSTRACT

<p><b>BACKGROUND</b>Topotecan is one of active agents for relapsed small cell lung can-cer (SCLC), some studies have shown that it is effective against SCLC as the first-line drug. This study is to assess the efficacy, toxicity and survival rate of topotecan plus cisplatin (TP) versus etoposide plus carboplatin (CE) in patients with previously untreated SCLC.</p><p><b>METHODS</b>Sixty-four patients with previously untreated SCLC were randomly assigned to receive either TP or CE. Topotecan 0.75 mg/(m²×d) via a 30-min intravenous infusion on days 1 to 5 and cisplatin 25 mg/(m²×d) on days 1 to 3 with hydration were given to patients in TP group. Carboplatin 300 mg/m² on day 1 and etoposide 100 mg/d on days 1 to 5 were given to patients in CE group. Treatment was repeated every 21 days. Responses and toxicities were evaluated in patients who received two cycles of chemotherapy. Patients with limited disease SCLC received thoracic irradiation or operation after the completion of chemotherapy.</p><p><b>RESULTS</b>Overall response rate was 75.0% in TP group and 68.8% in CE group. The median survival time was 10.5 months in TP group and 9.6 months in CE group. 1-, 2- and 3-year survival rate were 40.6%, 18.8% and 9.4% in TP group and 34.4%, 15.6% and 9.4% in CE group respectively. There were no significant differences in response rate, median survival time and survival rate between two groups (P > 0.05). Myelosuppression, nausea and vomiting, and alopecia were the most common toxicities, there was no significant difference in grade III and IV toxicities between two groups (P > 0.05).</p><p><b>CONCLUSIONS</b>TP has similar response rate and survivals with CE, and its toxicities are acceptable. TP regimen is an effective first-line treatment for SCLC.</p>

ABSTRACT

[Objective]To study the possibility of drug inhibition of wear particle induced osteolysis and aseptic prosthesis loosening in vivo.[Methods]4?8 mm transverse holes were made in femur condyle and tibia plateau of 12 adult rabbits bilaterally.One milligram of CoCr alloy(mean 5.38 ?m),Ti-6Al-4V(mean 3.21 ?m) and UHMWPE(12~200 ?m) particles were implanted into the holes separately.The animals were divided into 4 groups and each group had the same particles combination.Oral drug therapy twice a day was adopted with non-selective COX inhibitor(indomethacin,0.5 mg/kg BW),membrane Ca2+ channel inhibitor(nitrendipine,0.1 mg/kg BW),osteoclast inhibitor(alendronate sodium,0.1mg/kg BW) and blank control(0.9% saline) to the 4 groups separately and randomly according to the double blind principle,which started on the 2nd day postoperatively until 12 weeks at the time of sacrifice.Routine histological observation and calculation of the ratio of bone area(BA) to total tissue area(TTA) were done under the computerized analysis system.[Results]CoCr and Ti alloy particles could seldom be seen in the slices of the groups which showed normal cancellous bone.There were obvious macrophage infiltration and fibroblast proliferation round the particulate UHMWPE in the group of blank controls.It was similar in the groups of indomethacin and nitrendipine though the histological reaction was a little bit weaker and osteotoid tissue could occasionally be seen.UHMWPE particles were totally enclosed in the cancellous bone with little fibrous tissue proliferation in the group of alendronate sodium and the BA/TTA ratio was significantly higher than those at the other groups(P0.05).[Conclusion]This indicates the possibility of inhibition or prevention of osteolysis induced by wear particles by drug therapy especially when alendronate sodium is adopted,and it has significant clinical implications for controlling the most common cause of implant failure.
