Objective: To explore the efficacy of mild moxibustion plus loratadine tablets for children with allergic rhinitis (AR).Methods: A total of 80 children were randomized into a control group and an observation group, with 40 cases in each group. The control group was treated with loratadine tablets, and the observation group was treated with mild moxibustion plus loratadine tablets. Before and after treatment, the total nasal symptom score (TNSS) was evaluated, and the serum eosinophils (EOS) count, and the interleukin (IL)-27 and macrophage migration inhibitory factor (MIF) levels were measured. Clinical efficacy was evaluated after treatment. Results: The total effective rate of the observation group was higher than that of the control group (P<0.05). After treatment, the TNSS in both groups decreased (P<0.05), and the TNSS in the observation group was lower than that in the control group (P<0.05); the serum EOS count in both groups decreased (P<0.05), and the serum EOS count in the observation group was lower than that in the control group (P<0.05). The serum IL-27 level in the control group had no statistical difference compared with the same group before treatment (P>0.05), and the serum MIF level decreased after treatment (P<0.05). The serum IL-27 level in the observation group increased after treatment (P<0.05), and the serum MIF level decreased after treatment (P<0.05), and were both statistically different from those in the control group (P<0.05). Conclusion: Mild moxibustion plus loratadine tablets is effective in treating children with AR. It can significantly improve the nasal symptoms and reduce the serum EOS count, which may be related to the regulation of the serum IL-27 and MIF levels.

OBJECTIVETo explore clinical outcomes of posterior malleolar fractures with medial-extension type through posterioromedial and posteriorlateral incision.

METHODSFrom January 2008 to January 2011,25 patients with posterior malleolar fractures with medial-extension type were treated by hollow lag screw. Among them, 15 patients were treated through posteromedial incision,including 9 males and 6 females,aged from 21 to 67 years old with an average of 48.1 +/- 1.3; there were 5 cases with type A, 6 cases with type B and 4 cases with type C,according to Denis-Weber classification. Ten patients were treated by through posterior-lateral incision,including 6 males and 4 females, aged from 23 to 64 years old with an average of 46.9 +/- 1.5; there were 3 cases with type A, 5 cases with type B and 2 cases with type C,according to Denis-Weber classification. Operation time, blood loss, length of incision, times of X-ray exposure and complications of two groups were recorded and compared, Baird-Jackson effective evaluation were applied for evaluate clinical outcomes.

RESULTSAll patients were followed up from 12 to 49 months with an average of 20.6 months. There were significant differences in operation time, blood loss, times of X-ray exposure and complications between two group (P < 0.05). While there was no obvious meaning in clinical outcomes between two groups (P > 0.05).

CONCLUSIONTreating posterior malleolar fractures with medial-extension type through posteromedial approach can expose and fix fracture under direct vision, has advantages of shorter operation time, less X-ray exposure and blood loss, is a good choice of surgical approach.

Objective To investigate the possible effects and underlying mechanisms of desferroxamine (DFO) preconditioning against hypoxia in neurons. Methods Cortical neurons were cultured in DFO under ischemia condition of oxygen-glucose deprivation (OGD). Cell viability was determined by cell counting kit-8 (CCK-8) method; apoptotic cell ratio was examined with Hoechst 33342 staining; the morphological change was observed. Middle cerebral artery was occluded with or without DFO administration to establish the cerebral ischemia rat model. Infarct sizes were examined by TIC staining, and the neurological severity score was evaluated. Meanwhile immunofluorescent staining was employed to detect the protein synthesis of hypoxia inducible factor-1 (HIF-1) and erythropoietin (EPO), RT-PCR was performed to detect the mRNA expression of HIF-1 and EPO as well Results Neuronal viability kept in 49% (OGD group was 25%, t =8. 544, P<0. 05), the rate of apoptosis was 38% (OGD group was 30%, t = 4. 409, P <0.05 ) after administration of DFO (post-DFO) , the morphology of neurons improved. In the model of focal cerebral ischenfia of 30 mg/kg group, neurological severity score was reduced, the percentage of brain infarct decreased 8.5% (t=4.649, P<0.05) 3 days post-DFO(vs control). In the 100 mg/kg group, neurological severity score was 7.44 ±0.39 (t=2.903, P<0.05 ) ,5.60±0.47 (t=10.143, P < 0.01 ) ,6.97 ±0.73 (t=3.142, P<0.05 ), the percentage of brain infarct decreased 12. 0% (t=5.056, P<0.05), 32.3% (t =10.993, P<0.01), 10.6% (t =4.385, P<0.05)2,3 and7 days post-DFO(vs control), respectively. Immunofluorescent staining found synthesis of HIF-1α and EPO in cultured cortex neurons after DFO pretreated; HIF-1α and EPO were upregulated in the neurons of rat brain after DFO pretreated. The mRNA of HIF-1α and EPO upregulated in vivo and in vitro. Conclusion DFO preconditioning can protect the brain against ischemic damage, which is related to the protective effect on neurons. The mechanism of DFO preconditioning may be involved in the expression of HIF-1α and EPO in vivo and in vitro.

Objective To test the efficiency of gene transfer and expression mediated by ultrasound and microbubble strategy in 293T cell. Methods SonoVue microbubbles were mixed with pla.smid DNA encoding hAng-1 and green fluorescent protein. The mixture of the DNA and microbubbles was administer to cultured 293T cells by ultrasound exposue. The ultrasound condition was 1. 5 W/cm~2 and 30 s. Forty eight hours later, transfer rate was assessed by fluorescence microscopy and flow cytometry. Cell viability was assayed by Trypan Blue staining. RT-PCR and Western blot analysis was used to examine the expression of hAng-1 mRNA and protein. Agarose gel electrophoresis was used to evaluate the integrity of the plasmid. Results The transfection expression rate of eGFP in 293T cells was markedly increased with the additon of 20% microbubbles and 15 mg/L DNA. Fetal calf serum had no influence on the gene transfer rate. Ultrasound irradiation combined with microbubbles couldn't destroy the integrity of plasmid. Conclusions Ultrasound-mediated microbubbles destruction can increase the transfection and expression of hAng-1 gene in 293T.

Objective To certificate the effects on transfection ratio and cells viability of ultrasound (US) acoustic intensity, radiation duration, microbubbles concentration and DNA concentration in delivery human angiopioetin-1 gene (hAng-1) into 293T cells by SonoVue microbubbles and decide the optimal transfection parameters. Methods Mix 293T cells and SonoVue microbubbles linked with eGFP-C_3-hAng-1 in a different way, detect the gene transfection ratio and cells viability under the various US intensity, radiation duration, microbubbles and DNA concentrations. Results The gene expression would be increased if enhanced the intenstiy of US,radiation time,microbubbles and DNA concentrations,and the cells viability would be kept more than 90% ( P <0. 01). Whereas,if the US intensity increased over 1. 5 W/cm~2 ,the duration over 30 s and microbubbles and DNA concentrations over 20% and 15 mg/L respectively,the gene expression would not increase significantly ( P > 0. 05),whereas coupled with obviously decreased cells viability( P <0. 01). Conclusions The optimal conditions of deliver hAng-1 gene into 293T cells by SonoVue microbubbles was mixing cells and microbubbles in a cell wall-sticky way,US intensity was 1. 5 W/cm~2, duration 30 s,20% microbubbles and 15 mg/L DNA concentration.

Objective To sum up the diagnosis experience of unexplained hepatitis with hyperbilirubinemia (UHH) for establishing its diagnostic pathways and etiological factors. Methods By referring to the research progress at home and abroad, various examination items were made in order to form the clinical diagnosis pathway of UHH, on the basis of retrospective analysis and follow-up investigation of UHH patients. Using this pathway we carried out prospective diagnosis analysis for 223 patients admitted to Fifth Medical Center of Chinese PLA General Hospital from June 2014 to June 2017, in the order of preliminary, in-depth, and ultimate screening. Results A total of 181 cases were identified through the pathway screening (181/223, 81.17%). Two cases were etiologically diagnosed by primary screening (2/223, 0.90%), 18(18/223, 8.07%) by in-depth screening, and 161(161/223, 72.20%) by ultimate screening. There were still 42 cases (42/223, 18.83%) failing to make a definite diagnosis, among which 14 cases (14/223, 6.28%) failed to make a definite diagnosis after completing the diagnostic pathway, and 28(28/223, 12.55%) failed to complete the diagnostic pathway due to the critical condition and failure of liver puncture or rejection of genetic test. Among the 195 patients who completed diagnostic pathway, 181 cases were identified, and the actual etiology diagnosis rate was 92.82%. Among the 223 cases, 143(64.13%) were caused by drug-induced liver damage, 11(4.93%) by hereditary metabolic liver disease, 8(3.58%) by autoimmune liver disease, 5(2.24%) by infectious diseases, 14(6.28%) by other systemic diseases, and 42(18.83%) by undetermined causes. Conclusion Drug-induced liver damage, and genetic metabolic liver disease are common causes of UHH. The three-step screening pathway is effective for the diagnosis of UHH, and also simple and easy to practice, thus being worthy of promotion on a trial basis.

Objective To investigate the transfection efficacy and expression of Ang-1 gene and proangiogenesis in vitro and vivo by ultrasound-mediated microbubble destruction.Methods 293T cells were divided into three groups:group A was given hAng-1 plasmid and microbubbles plus ultrasonic irradiation,group B was given hAng-1 plasmid and ultrasound,group C was given hAng-1 plasmid only (without ultrasound).Forty-eight hours after transfection,the transient expression rate was observed under fluorescence microscopy and flow cytometry.RT-PCR and Western blot analysis were taken to evaluate the mRNA and protein expression of Ang-1 respectively.Twenty-seven rabbit models of ligated left circumflex branch coronary artery were divided into 3 groups randomly as follow:group Ⅰ (accepted intravenous injection of SonoVue microbubble and Ang-1 plus ultrasonic irradiation),group Ⅱ (accepted intravenous injection of Ang-1 with ultrasound),group Ⅲ (control group).Myocardial contrast echocardiography (MCE) was executed on all animals before and after the treatment.Two weeks after gene delivery,RT-PCR and Western blot analysis were taken to evaluate mRNA and protein expression of Ang-1 respectively.Microvessel density (MVD) counting of infracted myocardium,observed by Factor Ⅷ immunochemical staining,was performed to value the proangiogenesis effect of Ang-1 delivered by ultrasound mediated cavitation of microbubble.Results Green fluorescence was observed in group A and B by fluorescence microscopy,which was negative in group C.The transfection expression rate was significantly improved in group A ( P ＜ 0.01).In vivo,Microbubbles could be observed in former ischemic myocardium in MCEexamination and the Ang-1 mRNA and protein could be detected in group Ⅰ.On the other hand,the contrast agent was defected obviously and none of the animals showed Ang-1 mRNA and protein expression in other two groups.The MVD counting showed significant improvement in group Ⅰ whereas other two groups didn't.ConclusionsMicrobubble-enhanced ultrasound exposure can improve the Ang-1 gene transfection expression rate observably both in vitro and in vivo.This strategy for delivering has great proangiogenesis effect in vivo.

Objective To explore the capability of Ang-1 gene delivery to acute myocardial infarction using targeted microbubbles carrying ICAM-1 antibody.Methods Thirty-seven rabbits' left circumfles branch coronary arteries were ligated for models.Three rabbits were injected with microbubbles carrying ICAM-1 to detect the ability of targeting.Thirty-four rabbit models were divided into 3 groups randomly as follow:IM group (n=12,accept direct intramuscular injection),ICAM-1 group (n=12,accept intravenous injection of targeted microbubbles and Ang-1) and control group (n=10,without any treatment).Ultrasonography were executed on all animals before and 2 weeks after the treatment.All rabbits were killed after 2 weeks and examined for Ang-1 mRNA and protein by RT-PCR and Western-Blot respectively.Microvessel density (MVD) counting of infracted myocardium,observed by factor Ⅷ immunochemical staining,was performed to value the proangiogenesis effect of Ang-1 delivered by targeted microbubbles carrying ICAM-1 antibody.The liver and the kidney in ICAM-1 group were taken to assess the systemic delivery.Results IM and ICAM-1 group showed significantly improvement in the ejection fraction (P＜0.05) while control group did not.Ang-1 mRNA and protein could be detected in IM and ICAM-1 group;however,the expression between the two groups showed no siginificant difference.None of the control animals showed Ang-1 expression.compared with ICAM-1 group,the MVD was greater in IM group.Ang-1 was not detected either in liver or in kidney in ICAM-1 group.Conclusions Targeted microbubbles carrying ICAM-1 antibody can deliver Ang-1 gene to ischemic myocardium directly.Meanwhile,it's as effective as IM injections besides the greater angiogenesis effect.This strategy improves the perfusion of acute myocardial infarction and the function of heart.
