OBJECTlVE To study the effect of ganoderma poIysaccharide( GLP)on zebrafish ( Danio rerio)survivaI,deveIopment and senescence. METHODS A p53-knockout zebrafish modeI was estabIished by injecting of morphoIino phosphorodiamidate(mO)into normaI zebrafish eggs in the singIe ceII deveIopment stage. Different concentrations of GLP 1,2 and 3 g·L-1 were used to treat both wiId type and p53-knockout zebrafish embryos 8 h post fertiIization(8 hpf)under 28℃ for 3 d. The survivaI and maIformation rates were caIcuIated after 72 hpf,and the effect of GLP on ceII senescence was evaI-uated by senescence associated β-gaIactosidase(SA-β-gaI)staining both in wiId type and p53-knockout zebrafish embryos. In addition,the differentiaI gene expression of cancer inhibitor gene(p53),teIomer-ase reverse transcriptase( TERT),murine doubIe minute2( mdm2)and p21 was examined by RT-PCR both in wiId type and p53-knockout zebrafish embryos after treatment with different concentrations of GLP. RESULTS GLP 1 and 2 g·L-1 had no effect on deveIopment of wiId type zebrafish embryos,but after GLP 3 g·L-1 treatment,most of zebrafish embryos dispIayed maIformation and the survivaI rate was onIy 48.6%. GLP 1,2 and 3 g·L-1 had no effect on survivaI and deveIopment of p53-knockout zebrafish embryos. After GLP 2 g·L-1 treatment for 3 d,the SA-β-gaI staining positive rate of wiId type zebrafish embryos was reduced compared with controI group(P﹤0.01),whiIe there was no significant change in p53-knockout zebrafish embryos. The resuIts of RT-PCR showed that GLP 2 g·L-1 treatment depressed p21 and p53 gene expression(P﹤0.05,P﹤0.01),and had no effect on mdm2 and TERTgene expres-sion of wiId type zebrafish embryos. For p53-knockout zebrafish embryos,the TERT,mdm2,p21 and p53 gene expression dispIayed no significant difference after GLP 2 g·L-1 treatment. CONCLUSlON GLP 2 g·L-1 may improve senescence of wiId type zebrafish embryo ceIIs. GLP ≥3 g·L-1 may Iead to death and abnormaI deveIopment of wiId type zebrafish embryos. The improvement of GLP on senescence of wiId type zebrafish embryo ceIIs might be mediated by its down-reguIation of p21 and p53 gene expression.

Objective To evaluate the safety and efficacy of interventional procedure for treating the renal artery aneurysm (RAA).Methods From Jan 2009 to Apr 2014,17 patients,who were diagnosed as RAA and accepted the interventional therapy,were reviewed in our hospital.The mean age in those patients,including 7 males and 10 females,was (46.4±10.3) years old (range from 20 to 67 years old).The related symptoms included backache in 4 cases,abdominal pain in 4 cases,intermittent hematuria in 2 cases,chyluria in one case,oligouria in one case.9 cases were diagnosed as multiple RAA and 8 cases were confirmed as signle cases.In 17 cases,31 aneurysms were found,including 26 true aneurysms,5 pseudoaneurysums,17 sacculated aneurysms,4 spindle-like aneurysms,4 irregular shape aneurysms,4 parenchyma aneurysm and 2 dissecting aneurysm.8 aneurysms located in the main renal artery,19 aneurysms located in the branch of renal artery,4 aneurysums located in the renal parenchyma.Intracavitary coil embolization was used in 4 patients.We carried out parent artery embolization in 3 patients.A combination of the former techniques was performed in 6 cases.Covered stent placement was operated in one case.Combination of the intracavitary coil embolization and nude stent placement were performed in 2 patients.We used two techniques in one patient with multiple artery aneurysms in both sides.Results The interventional treatment of RAAs succeed at the first operation in 16 of 17 patients.17 cases were followed-up from 3 to 53 months (mean 23 months).No severe complications or death cases occurred in this study.Urine occult blood in 3 patients turned to negative after one week.Primary symptoms such as gross hematuria,abdominal pain,lumbodorsalgia,fever vanished or obviously eased after a month.Laboratory tests showed that normal level in SCr,BUN,routine urinalysis 3 months,6 months and 1 year later.No tendency of stent and coil stent shifting was found in 16 patients and the parent arteries were patent in 8 cases,with reexamination bv ultrasonic or computed tomography angiography (CTA).Conclusions Interventional techniques are minimally-invasive,safe and effective methods for treating the RAAs.

Objective To evaluate tumor angiogenesis and clinical significance by contrast-enhanced CT in case of non-small cell lung cancer (NSCLC). Methods 30 patients with NSCLC underwent dynamic thoracic CT, and histopathological slides were carefully prepared for VEGF immunohistochemical staining. Maxium attenuations of dynamic CT were compared with VEGF expression levels and lymph-node metastases. Results The mean peak attentation was (36.28?6.41)HU, VEGF positive expressions were in 21 patients, and negative expressions were in 9 patients. VEGF expression levels in patients with NSCLC stage II and III were higher than those in stage I , and in lymph node metastases group, the expression levels of VEGF were also higher than those in non-metastatic nodes. CT enhancement of NSCLC was positively related to VEGF expression,neoplasm stage and lymph-node metastases. Conclusion CT enhancement of NSCLC can reflect tumor angiogenesis and correlate to lymph-node metastases closely, help lung cancer diagnoses,neoplasm stage, and serve as a supplement to the present staging system for lung cancer in biological behavior.

ood long-term efficacy for cirrhosis patients with portal hypertension was a useful treatment for these patients.

Although empirically well understood in their clinical administration, volatile anesthetics are not yet well comprehended in their mechanism studies. A major conundrum emerging from these studies is that there is no validated model to assess the presumed candidate sites of the anesthetics. We undertook this study to test the hypothesis that the single-celled Paramecium could be anesthetized and served as a model organism in the study of anesthetics. We assessed the motion of Paramecium cells with Expert Vision system and the chemoresponse of Paramecium cells with T-maze assays in the presence of four different volatile anesthetics, including isoflurane, sevoflurane, enflurane and ether. Each of those volatiles was dissolved in buffers to give drug concentrations equal to 0.8, 1.0, and 1.2 EC50, respectively, in clinical practice. We could see that after application of volatile anesthetics, the swimming of the Paramecium cells was accelerated and then suppressed, or even stopped eventually, and the index of the chemoresponse of the Paramecium cells (denoted as I ( che )) was decreased. All of the above impacts were found in a concentration-dependent fashion. The biphasic effects of the clinical concentrations of volatile anesthetics on Paramecium simulated the situation of high species in anesthesia, and the inhibition of the chemoresponse also indicated anesthetized. In conclusion, the findings in our studies suggested that the single-celled Paramecium could be anesthetized with clinical concentrations of volatile anesthetics and therefore be utilized as a model organism to study the mechanisms of volatile anesthetics.

BACKGROUND: Compared with the traditional organic fluorescent dyes, quantum dots present good biomarker characteristics. Especially, quantum dots for cell labeling and targeted bioimaging present unique optical properties.OBJECTIVE: To investigate the biocompatibility of CdSe/ZnS quantum dots with mononuclear macrophages.METHODS: The macrophages RAW264.7 were inoculated into 96-well plates containing 0, 50, 100 mg/L CdSe/ZnS quantum dots for 1 or 2 hours. Then, the fluorescent signal was detected by flow cytometry. After 0-24 hours of culture,the fluorescence signal intensity of the macrophages cultured with 50 mg/L CdSe/ZnS quantum dots was detected by flow cytometry. After 18 hours of culture, quantitative PCR was used to detect the levels of tumor necrosis factor α and interleukin 1β in macrophages, and macrophage proliferation cell apoptosis were detected by MTT and flow cytometry,respectively.RESULTS AND CONCLUSION: The fluorescence signal intensity was positively correlated with the mass concentration of CdSe/ZnS quantum dots, and the intensity of the fluorescent signal was increased with the labeling time. After labeling using 50 mg/L CdSe/ZnS quantum dots, the fluorescence signal of macrophages increased continuously with time, and reached the peak at 18 hours. Compared with 0 mg/L quantum dot group, 50, 100mg/L quantum dot groups could significantly promote the expression of tumor necrosis factor α and interleukin 1β in macrophages (P < 0.01 or P < 0.05).The level of tumor necrosis factor α in the 100 mg/L quantum dot group was higher than that in the 50 mg/L quantum dot group (P < 0.01). The expression of interleukin-1β showed no difference between 50 and 100 mg/L quantum dot groups.The cell proliferation in the 50 and 100 mg/L CdSe/ZnS quantum dot groups was significantly higher than that in the 0 mg/L quantum dot group (P < 0.05), but there was no difference between the former two groups. In addition, 50 and 100 mg/L CdSe/ZnS quantum dots had no significant effect on apoptosis of macrophages. To conclude, CdSe/ZnS quantum dots could activate macrophages and promote their proliferation and secretion of inflammatory factors, but did not affect their apoptosis.

Objective To investigate the precision and trueness of results from six imported commercial systems for measurement of gamma-glutamyltransferase (GGT) in serum in order to provide reference for the clinical laboratories to verify the target accuracy. Methods Five fresh frozen human serum samples that differed in catalytic concentration were analyzed in two candidate domestic reference laboratories and the target values for GGT were assigned using IFCC reference measurement procedure. The same samples were tested by six commercial systems which were calibrated using the matched calibrator. Each system consisted of five instruments in five laboratories, which had been well maintained before measurement. The data was collected. Precision from the same manufacturer and different manufacturers and biases between target values and mean values from each system were calculated. Results The differences of the mean values for five levels of commercial systems varied from 16. 1% to 35.4%. For the five levels, the coefficients of variation (CVs) of the results from all measurement system were from 5.3% to 8. 8% , and CVs from each level were A 2. 17%- 5.07%, B 4. 21%-10. 98%, C 0. 52%-2. 38%, D 1.35%-2. 59%, E 0. 23%-1..54%-), F 1.83%-2. 38%. Biases between the mean values of each commercial systems and the target values were A 0. 43% -8.41% ), B -1.49% - -13.04% ), C 11.20% -17.73% ), D 0. 19% -4. 62% ), E -0. 30% - -2. 63% ), F 4). 46%-7.90%, respectively. The investigation showed that biases of two manufacturers were less than a quarter of the total allowable error (TAE) of The Clinical Laboratory Improvement Amendments of 1988 (CLIA'88) in the whole range of investigated concentrations and the other two manufacturers' biases could meet a quarter of TAE in a relative limited range. The biases of two manufacturers were near or more than half of TAE in most levels. It also revealed that the biases of more than half of manufacturers were more than a quarter of TAE in the low or high level of investigated concentrations. Conclusions The mean values of each manufacturer were significantly different. The variances of commercial systems from different manufacturers were much higher than those from the same manufacturer. Some imported commercial systems for measurement GGT should be better calibrated with the reference method, especially in the whole measurement linearity.
