Objection To compare the efficacy and tolerance of perioperative intravenous Metoprolol or calcium iron antagonist injection on patients with cardiac complications which undergoing noncardiac surgery. Method The clinical data of 135 patients who underwent noncardiac surgery from March 2003 to May 2004 was analyzed. According to the different drugs used to treat the perioperative cardiac complications (tachycardia arrhythmia, hypertension and myocardium ischemia), patients were allocated to metoprolol group (87 cases) and calcium antagonist group (48 cases, including Verapamil 21 patients and Diltiazem 27 patients). The effects of the therapy on heart rate and blood ressure control and ischemia relieving were compared between two groups. Results There is no significant difference at baseline data between two groups. Compared with calcium antagonist, intravenous metoprolol could more reduce heart and relieve myocardium ischemia quickly. The effect of blood pressure controlling was more significant in calcium antagonist group than in metoprolol group. The incidence of side-effects events was lower in metoprolol ( 8.0%) than in calcium antagonist group (22.9%).Conclusions Intravenous metoprolol injection is effective and safe in treating perioperative cardiac complications in patients with noncardias surgery.

Total RNA was then extracted using the TRIzol reagent. The expression of chemokine receptors in these tissues were analyzed by way of semi-quantitative reverse transcriptase-polymerase chain reaction.Results:Compared to normal endometrium, the eutopic endometrium expressed significantly more CCR6, CCR8, CCR9 and CX3CR1(P

With the rapid development of medical imaging technique, iodinated contrast media (IOCM) has become the most commonly used agent in performing imaging diagnosis and interventional therapy. The use of IOCM, especially the use of non-ionic iodine contrast media, has been swiftly increased in recent years. The accompanying untoward reactions, such as allergic reactions, cardiovascular reactions, contrast media nephropathy, thyroid toxicity, etc. prove to be the new problems that greatly perplex the medical circle. With the continuous improvement of the knowledge to the untoward reactions, more and more physicians have paid attention to contrast media induced thyroid toxicity. At present, researches concerning iodine contrast media thyroid toxicity are still few, and the relevant research is particularly rare in China. This paper aims to make a review about the influence of different kinds of iodine contrast media on thyroid function.

OBJECTIVE: To observe the effect of ginseng fruit saponins (GFS) on insulin sensitivity index in high fat-fed rats. METHODS: An animal model of insulin resistance was established by injecting low dose of streptozotocin (STZ) in high fat-fed rats. Effect of GFS on insulin sensitivity was detected with glucose infusion rate (GIR) by euglycemic hyperinsulinemic clamp technique. RESULTS: The level of fasting blood glucose and insulin in untreated group increased more significantly than that in normal control group (P<0.05, P<0.01), while the index of GIR decreased significantly (P<0.01). As compared with the untreated groupìthe parameters of GFS-treated groups were improved significantly in a dosage-dependent manner (P<0.05, P<0.01). CONCLUSION: GFS can improve experimental insulin resistance in rats.

ObjectiveTo survey 0—6 years old disabled children in Guiyang.Methods4 999 children aged 0—6 years old chosen randomly from 9 145 children of 12 blocks were investigated with the disability sampling survey criteria of 1987.ResultsThe rate of disabled children in Guiyang was 1.58%, and was not significantly different compared with that of whole country (1.36%) and other three areas including Siping City (P>0.05),but significantly higher than that of other six districts including Heping district of Tianjin municipality (P<0.05). All kinds of disability found by this survey were separately intellectual disability (0.92%),comprehensive disability (0.28%),limb disability (0.24%),vision disability (0.10%),psychiatric disability (0.03%),and hearing disability (0.02%). Rates of intellectual and vision disabilities were significantly higher than that of whole country ( P>0.05).ConclusionSome diseases are directly relative to occurrence of disability. The poor income of the children family,lower education of his parents and not gotten preschool education were risk factors of disability. The institution based rehabilitation and community based rehabilitation are main rehabilitation forms to disabled children.

Objective To evaluate the response of the lung tumor xenografts in nude mice to antiangiogenic treatment from perspectives of anatomic,vessel function,cellular and molecular level using the multimodality imaging techniques including optical imaging,dynamic contrast enhanced MRI(DCE-MRI)and diffusion weighted imaging(DWI).Methods The green fluorescent protein(GFP)was transplanted labeled using GFP-expressing NCI-H460 cells.After the transfection of GFP,NCI-H460 cells were implanted subcutaneously into nude mice.Ten days after implantion,12 nude mice whose tumor xenografts grew to 0.5-1.0 cm in the maximum diameter were randomly divided into 2 groups,and injected with phosphate-buffered saline and recombinant human endostatin respectively.Then the nude mice in the two groups underwent optical imaging,DCE-MRI and DWI.The volumes,photon counts,the quantitative MR vessel functional parameters including volume transfer constant(Ktrans),rate constant(Kep),volume of extravascular extracellular space(Ve)and maximum area under the enhancement curve(iAUC),and apparent diffusion coefficient(ADC)values of the tumors were recorded.Then tumors were collected and observed using the transmission electron microscopy and pathology examination,including HE staining,microvessel density(MVD)and the expressions of vascular endothelial cell growth factor(VEGF).The Kep and VEGF expressions in experimental group and control group were compared with x2 text,and other values were compared with t test.The Pearson and Spearman test were used for analyzing the correlation of values in the two groups.Results Seven days after inoculation,the fluorescence signals were detected and grew with the growth of the tumors.On the 7 day after starting therapy,the photon counts of experimental group and control group were(2.51 ± 2.43)× 1010(photon/sec)and(5.77 ± 3.25)× 1010(photon/sec),respectively with no significant differences(t =1.964,P ＞0.05).Two sample t test showed that the tumor volumes in experimental group were smaller than those in control group[(365 ± 56)vs(987 ± 265)mm3,t =0.001,P ＜ 0.01].There was a positive correlation(r =0.673,P ＜ 0.05)between the photon counts and the volumes of the tumors.The mean Ktrans,Kep,Ve and iAUC of experimental group were:(0.055 ±0.012)min-1,0.335(0.184—0.894)min-1,0.297 ± 0.041 and 7.334 ± 3.930,and those for control group were:(0.117 ± 0.027)rin-1,0.417(0.324-1.736)min-1,0.326:±:0.062 and 13.280 ± 4.245.There were significant differences of Krans and iAUC(t =5.155,2.518,P ＜ 0.05)between experimental group and control group.And there was a positive correlation(r =0.715,P ＜ 0.0 1)between the values of iAUC and MVD,but not the expressions of VEGF(r =0.484,P ＞ 0.05).The values of ADC in experimental group were higher than that in control group[(791 ± 38)× 10-6 vs(737 ± 43)×10-6 mm2/s],and there were significant differences(t =-2.299,P ＜ 0.05).Two sample t test showed that the MVD in experimental group were lower than that in control group[(11.9 ± 4.8)vs(19.2 ±4.3)item/hpf,t =2.774,P ＜ 0.05].The VEGF expressions in experimental group were lower than that in control group(x2 =4.000,P ＞ 0.05).It was observed that some cells in experimental group had degenerated and apoptotic signs by the electron microscopy.Conclusions Evaluating the response of lung tumor xenografts to antiangiogenic treatment at anatomical,vessel functional,cellular and molecular level using the multimedality imagings is applicable.And it will be in favour of evaluating the therapeutic effect promptly.

ObjectiveTo share the experience of arterial plasty and reconstruction of variant arteries in living donor liver transplantation. MethodsFrom September 2006 to May 2010, 73 living donor liver grafts (64 cases using the right lobe,9 cases using left lobe) were used in patients with end-stage liver disease. The hepatic arteries were evaluated preoperatively with computed tomography and magnetic resonance angiography. Back-table arterial plasty was performed under a microscope or a loupe according to arterial variation. We described technical points based on anatomic variations. There were 13 (17. 8 ％) liver grafts with anatomic hepatic arterial variations and all of these cases were subjected to back-table reconstruction with interrupted 8-0 or 9-0 nonabsorbable nylon monofilament sutures according to the diameter of artery. ResultsIn 3 cases, the associate right hepatic arteries that were arisen from superior esenteric arteris (SMA) were reconstructed to cystic arteries. In 2 cases with the associate right hepatic arteries arisen from the abdominal trunk, the right hepatic arteries and associate right hepatic arteries of donors were anastomosed with right hepatic arteries and left hepatic arteries in recipients respectively. In 2 donors, hepatic arteries had branches, which were reconstructed. All of the arterial plasty were conducted on a back table. No arterial thrombosis was found during a postoperative follow-up period of 6 months. ConclusionLive donor liver transplantation using the right lobe with hepatic artery variation can be performed safely, but there is a potential operative risk of severe complication after transplantation. Tominimize operative difficulties and complications, back-table reconstruction should be applied and proper treatment is given according to individual situations to ensure a safe and satisfactory outcome

Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.
