Objective:To investigate the clinical efficacy and safety of Reduning injections in the treatment of infantile rotavirus enteritis. Methods:Totally 102 cases of infantile rotavirus enteritis in our hospital from June 2012 to June 2013 were randomly divided into two groups, the control group had 50 patients, and the treatment group had 52 cases. Both groups were given conventional symp-tomatic treatment, the control group was given 10 mg·kg-1 ribavirin injections in 100ml glucose injections for intravenous infusion, qd, and the treatment group was given 0. 5 ml·kg-1 Reduning injections in 100ml glucose injections for intravenous infusion, qd. Ev-ery 3-day was a course of treatment. The clinical curative effect of the two groups was observed, and the clinical symptoms, hospitaliza-tion time and adverse reactions were also studied. Results:After the treatment, the total effective rate in the control group was 70. 0%, while that in the treatment group was 92. 3%, and there was significant difference between the two groups (P<0. 05). The clinical symptom disappearance time and hospitalization time in the treatment group were significantly lower than those in the control group with statistically significant difference (P<0. 05). During the treatment, the control group had 5 cases of leucopenia and 2 cases of skin rash, and the patients all recovered after withdrawal of the drug, while the treatment group showed no obvious adverse reaction. Con-clusion:The curative effect of Reduning injections in the treatment of infantile rotavirus enteritis is promising, which can effectively improve the clinical symptoms, shorten the course of disease and reduce adverse reactions with the value of clinical application.

Objective: To evaluate the application of two-dimension and color Doppler ultrasound in diagnosis and differential diagnosis of fascial space infection in maxillofacial region. Methods: Retrospective analysis was conducted on 87 cases of maxillofacial space infections, among which there were 6 suspected cases of accompanying tumor.Results: In the 87 cases, 53 had abscess formation, confirmed by operative drainage or puncture biopsy. The pathological studies revealed 2 cases of Non-Hodgkin's lymphoma, and 1 case of branchial cleft cyst accompanied with infection. The 3 cases showed characteristic appearance in ultrasonic imaging. The space infection presented stronger echogenicity than that in tumors. In this study, 95% (83/87) cases showed grey or medium echogenic dots, while 4.5% (4/87) cases did not show obvious echogenic dots due to a large amount of abscess, and 2 cases of tumors, however, did not show any echogenic dots. In addition, 87% (76/87) cases had few blood flow in the lesion areas, and 22% (2/87) cases had much blood flow in the lesion areas. All cases showed that the lesion areas and the blood flow reduced obviously with enhanced echo following anti-inflammatory treatment except 2 cases accompanied with tumor without obvious changes in lesion areas and blood flow.Conclusion: The ultrasonic diagnosis with two dimension and color Doppler ultrasound has high accuracy in diagnosis of maxillofacial space infection, with accordance rate up to 96.6%, much higer than CT/MRI. It is suggested that the two dimension and color Doppler ultrasound can be used as a prior choice of diagnosis.

[Summary] 2015 AACE/ACE Clinical Practice Guidelines for Integrated Management of Diabetes are updated and revised on the basis of 2011 edition. The guidelines highlight the comprehensive consideration of micro- and macro-vascular risks rather than merely focusing on the strategies and approaches of glycemic control. The guidelines also emphasize individualized targets for weight loss and the management of hyperglycemia ,dyslipidemia and hypertension and that more attention should be paid to safety of individualized treatment other than efficacy.

Objective:To evaluate the effects of surface modified nano titanium-oxide on the mechanical properties of A-2186 silicone elastomers. Methods:Added surface modified nano titanium-oxide into A-2186 silicone elastomers with 0.0%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5% and 3.0% additions according to the ASTM standard. The mechanical properties of A-2186 silicone elastomer including the tensile strength, the broken elongation, the tear strength and the Shore-A hardness were tested separately. The section of samples were investigated by scanning electron microscope and energy spectrum analysis. Used statistics method to analyse the results. The results were analysed with software EPSS 13.0. Results:With the addition of nano titanium-oxide increasing, the tensile strength, the broken elongation and the tear strength of A-2186 silicone elastomers increased firstly, and then decreased. While the Shore-A hardness of A-2186 silicone elastomers increased gradually. When the addition of surface modified nano titanium-oxide reached to 2.0%, the nano titanium-oxide dispersed well in the base without agglomeration. Under such condition, the A-2186 silicone elastomer showed the best general mechanical properties:the tensile strength was (6.54?0.55) MPa, the broken elongation was 618.00?7.58(%), the tear strength was (16.64?0.52) kN/m and the Shore-A hardness was (31.00?0.79) U. Conclusion:The mechanical properties of A-2186 silicone elastomers are improved most greatly with 2.0% addition of surface modified nano titanium-oxide to the base of A-2186 silicone elastomers.

Erythropoietin(EPO) has an anti-apoptotic effect,and promotes the proliferation and differentiation of erythroid progenitor cells. Several studies have indicated that EPO can protect photoreceptor cells from the lightinduced retinal degeneration ;protect retinal neurons from ischemia-reperfusion injury and retinal ganglion cells after acute and chronic ocular hypertension; promote ganglion cell survival and axonal regeneration after optic nerve transaction; attenuate inflammation in multiple sclerosis optic neuritis; reduce the permeability of the retinal barrier and protect retinal neurons in diabetic retinopathy; enhance the stability of hypoxic retinal vessels in retinopathy of prematurity. Herein,we review the distribution of EPO and its receptor in retina,their expression in animal model of retinal diseases,and their effects and mechanisms in protection of retinal neurons and optic nerve.

Objective To investigate the expression of macrophage migration inhibitory factor (MIF) and CD_(74), the receptor of MIF, in preeclamptic placenta and its correlation with the pathogenesis of preeclampsia.Methods From March 2008 to November 2008,69 preeclamptic women who delivered in the Department of Obstetrics, Affiliated Hospital of Qingdao University Medical College,were recruited,including 33 women with mild preeclampsia (MPE group) and 36 women with severe preeclampsia (SPE group).Another 43 healthy pregnant women were taken as control group.Immunoturbidimetry was applied to measure the concentrations of C-reactive protein (CRP) in maternal blood.The expressions of MIF and CD_(74) in placenta were tested with immunohistochemistry and the expressions of MIF mRNA and CD_(74) mRNA were detected by semiquantitative RT-PCR.The relationship between maternal blood level of CRP and MIF mRNA and CD_(74) mRNA in placenta was analyzed in the MPE and SPE group.Results (1) MIF and CD_(74) were expressed in the placenta of all pregnant women in the 3 groups, as shown in brown-yellow color, and significantly higher expression was found in the MPE and SPE group.(2) The expression of MIF mRNA and CD_(74) mRNA in the MPE group (0.70±0.13 and 0.96±0.16), SPE group (0.88 ± 0.12 and 1.08 ± 0.15) were significantly higher than in the control group (0.67 ± 0.11 and 0.83 ± 0.14) (P < 0.01), and statistical significance was also found between the MPE and SPE group (P <0.01).(3)The maternal blood concentrations of CRP in the MPE and SPE group were significantly higher than in the control group [(15.3±7.0) mg/L and (21.6±9.1)mg/L vs (4.8 ± 1.8) mg/L, P <0.01] , and significant difference was also found between the MPE and SPE group (P <0.01).(4) In the two preeclamptic groups, the blood concentrations of CRP were positively correlated with the expression of both MIF mRNA(r =0.67 ,P <0.01)and CD_(74) mRNA(r =0.83 ,P <0.01) in placenta.Positive correlation was also found between the levels of MIF mRNA and CD_(74) mRNA in placenta (r =0.93 ,P < 0.01).Conclusions Overexpression of MIF and CD_(74) in the placenta may up-regulate the CRP level in maternal blood, resulting in systemic inflammatory reaction and vascular endothelium damage which may be involved in the pathogenesis of preeclampsia.

ObjectiveTo study the expression of AKT2 gene in liver cancer and its relationship to tumor progression.MethodsThe expression of AKT2 in liver cancer was detected by SP immunohistochemical stainin and reverse transcription polymerase chain reaction (RT-PCR).Four patients with benign liver tumors were used as control.ResultsThe positive rates of AKT2 in liver cancer tissue and benign control tissue were 62.5％ (28/32) and 0％ (0/4),respectively.The difference was significant.In addition,a positive expression of AKT2 correlated significantly with poor differentiation,positive lymph node and distant metastasis.The median survival after surgery was significantly shorter in patients with positive than with negative AKT2 (76d vs 463d).ConclusionThe detection of AKT2 was useful in assessing the progression of liver cancer,in determining prognosis and eventually in rendering a possible target for novel therapeutic strategies.
