Objective To evaluate the protective effect of hydrogen-rich saline on renal ischemia/reperfusion (I/R) in mice. Methods Thirty C57BL/6 mice were randomly divided into 3 groups: sham-operated (SO) group, I/R group (mice were injected with 5 ml/kg saline by tail vein just before ischemia induction) and hydrogen-rich saline group (mice were injected with 5 ml/kg hydrogen-rich saline). At the 6th h after reperfusion, the sera and renal samples subject to IR injury were collected. The Scr and BUN levels in serum were determined and renal histological changes were also examined. The apoptosis of renal tubular epithelial cells was measured by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay. Malondialdehyde (MDA) contents in renal samples were measured using specific kits. The infiltration of F4/80 positive macrophages and neutrophils was assayed by using immunohistochemistry. The mRNA expression of TNF-α, IL-6, IL-1β and IL-17 was detected by using real time reverse transcription PCR. Results As compared with LR group, at the 6th h following reperfusion the levels of Scr and BUN were significantly reduced (P<0.05), histological changes obviously alleviated (P<0.01), apoptosis of renal tubular epithelial cells and MDA contents was decreased (P<0.05) in hydrogen-rich saline group. Moreover, the infiltration of macrophages and neutrophils, and the mRNA expression of TNF-α, IL-6, IL-1β and IL-17 in renal tissue in hydrogen-rich saline group were also declined as compared with IR group (P<0.05). Conclusion Hydrogen-rich saline can ameliorate renal IR injury to some extent, which is associated with inhibition of inflammatory response induced by reperfusion.

OBJECTIVETo evaluate the effect of electro-acupuncture (EA) on gastric mucosal oxygenation and systemic inflammatory response in patients undergoing endoscopic sinus surgery with controlled hypotension (CH), and to explore its protective effect on gastric mucosa.

METHODSFifty-four patients, 18-65 years old, grade I-II of American Society of Anesthesiology (ASA), who were scheduled for endoscopic sinus surgery were randomly assigned to two groups, group A (general anesthesia group) and group B (general anesthesia combined EA anesthesia group), 27 in each group. Conrolled hypotension was executed during operation, and mean arterial pressure (MAP) was maintained at 55-65 mmHg. After tracheal intubation gastric tesiometer catheter was indwelled through nasal cavity or oral cavity. After successful indwelling, it was connected with gastric mucosa monitoring mode of multifunctional parameters monitor. Patients' MAP and heart rate (HR), pHi, partial pressure of carbon dioxide (PgCO2), arterial partial pressure of carbon dioxide (Pg-aCO2) and endtidal pressure of carbon dioxide (Pg-etCO2) were measured and recorded at T, (immediately before induced hypotension), T, (20 min following induced hypotension to target MAP), T2 (40 min following induced hypotension to target MAP), T3 (20 min after ending induced hypotension), and T4(40 min after ending induced hypotension). Blood samples were intravenously collected, TNF-alpha, IL-1, and IL-6 were detected by ELISA 24 h before operation, during operation (T3), and 24 h after operation.

RESULTSAfter hypotension was induced, Pg-CO2, Pg-aCO2 and Pg-etCO2 increased significantly (P < 0.01, P < 0.05), while pHi decreased significantly (P < 0.01) in both groups at T1-T4 than those at T0. During T1-T4, PgCO2, Pg-aCO2, and Pg-etCO2 were higher (P < 0.01, P < 0.05), while pHi was lower in group A than in group B (P < 0.01). Furthermore, TNF-alpha, IL-1, and IL-6 increased significantly in both groups during operation and 24 h after operation, when compared with those 24 h before operation (P < 0.01, P < 0.05). TNF-alpha and IL-1 in group A were higher than those in group B (P < 0.05) during operation and 24 h after operation, but with no significant difference in the plasma concentration of IL-6 (P > 0.05).

CONCLUSIONEA exerted obvious protective effect of gastric mucosal injury in endoscopic sinus surgery with controlled hypotension, which might be achieved by increasing gastric mucosal blood flow, maintaining oxygen supply and demand, inhibiting inflammatory response, and alleviating injury of gastric mucosal barrier.

Objective:To investigate the possibility of using radioiodine labeled framework region(FR)antisense oligonucleotides(ASONs)as an imaging agent or antisense therapeutic radiopharmaceu-tical in lymphoma.Methods:A 18-mer partial phosphorothioate oligonucleotide sequence was synthe-sized and grafted in 5'with a tyramine group which was further radioiodinated.Radioiodination of the tyra-mine derivatized oligonucleotides was performed using the chloramine T method.(1)Normal CD-1 micewere injected via a tail vein with 148 kBq (125)~I-FR-ASON(2-3?g).Animals were sacrificed at the endof 1,2,4 and 24h,and tissue samples were studied.(2)Liposome-mediated 3.33 MBq (131)I-FR-ASON(7-9?g)were injected intralumorally into tumor-bearing BALB/c mice(6 weeks after innculation of10~7 Namalwa cells)meanwhile liposome-mediated (131)~I labeled sense oligonucleotides served as controls.Biodistribution was monitored by sequential scintigraphy and organ radioactivity measurement 24h afterinjection.Percentage of the injected dose per gram of tumor and tumor/non-tumor tissue ratios(T/NT)were calculated tot each group of mice and the difference between two groups was assessed.Results:The5′tyramine group allowed specific and stable radinlabeling of the ASON with radioiodine.The radioactivi-ty reached its peak 1h after injection,and then decreased rapidly in normal mice after intravenous ad-ministration of (125)~I-FR-ASON.The liver,stomach and intestine played an important role in biodistributionand radioactivity counts were low in bone,brain and blood.When (131)I-FR-ASON was injected intratumor-ally into mice grafted with Namalwa cell line,images showed the tracer accumulated in the tumor,Imme-diately after intratumoral administration,only the tumor was visible.Scintiscans performed at the end of 1and 2h showed elimination of the tracer from the tumor to the abdomen and at the end of 24h the tumorwas clearly seen.Percentage of the injected dose per gram of tumor and T/NT ratios for the sense group(control)were significantly lower than those of the antisense group.Conclusion:Radiolabeled Ig FRASON showed high specificity in V1 family B-cell lymphoma,which should be further investigated for nu-clear medicine imaging application and radionuclide antisense therapy.

The Coat protein and Maturase gene of E.coli bacteriophage MS2 was amplified by PCR,then the gene was cloned into pET32a to construct the intermediate vector pET32aCP.The conservative sequence of FMDV internal ribosome entry site(IRES) was cloned into the downstream of pET32aCP bacteriophage gene to construct the prokaryotic expression vector pCPES.The recombinant plasmid pCPES transformed into E.coli strain BL21(DE3) was induced to express with 1mmol/L IPTG.The expression products were purified by sucrose density gradient centrifugation.The expression products observed by TEM were circular viruslike particles,and the diameter of these particles was about 26nm.The stability of viruslike particles was detected,and the viruslike particles was identified by RTPCR.The results showed that the viruslike particles contain the FMDV IRES RNA and have good stability.The viruslike particles have great prospect as the standard and quality control in the area of RNA virus detection.
