Objective To assess the chest X-ray radiographic findings in children with influenza A (H1N1) virus infection. Methods The chest X-ray radiographies in 67 children with influenza A(H1N1) virus infection were reviewed in this study. The chest radiographies were obtained 3-8 days after the onset of symptoms and for the follow-up. Results The abnormalities were bilateral in 53 patients and unilateral in 7 patients. The predominant radiographic findings were bilateral patchy consolidation (n=42) with rapid confluence in 10 patients, lobular consolidation (n=7) with interstitial hyperplasia in 1 patient 3 month later, diffuse consolidation (n=11) with interstitial hyperplasia in all patients after 3 month. ConclusionThe predominant chest X-ray radiographic findings are bilateral patchy consolidation and diffuse consolidation with interstitial hyperplasia afterward.

Warfarin is one of the most widely used anticoagulants in clinical setting.There are great interindividual differences in both therapeutic efficacy and dose requirement,which greatly limits its application in clinic.This article summarizes the influence of genetic factors on interindividual and interethnic differences of warfarin,providing sufficient guidance for personalized medicine.

Objective To explore the effects of lamotrigine on the cognitive function and the quality of life in epilepsy patients.Methods This was a prospective study and 91 newly diagnosed epilepsy patients were enrolled.The neuropsychological tests score and the quality of life in epilepsy inventory(QOLIE-31) were obtained before and after the treatment with lamotrigine.A battery of neuropsychological tests comprised the auditory verbal learning test(AVLT), the logical memory test(LMT), the digital symbol test(DST), the stroop color word test(SCWT), the trail making test(TMT), the verbal fluency test(VFT), the WAIS block design test(WBDT), the WAIS digital span test(WDST)and the Boston naming test(BNT). Results The repeated assessments in the patients taking lamotrigine were associated with significant improvements in many domains.The greatest changes were observed in the immediate and delayed recall of AVLT, DST, the time consuming of SCWT card C and TMT test A and B, the immediate and delayed recall of LMT, VFT, WBDT and BNT.For the quality of life, significant improvements were recorded in the fields of the seizure worry(38.81?16.06 vs 45.68?15.18), the overall quality of life(59.12?13.50 vs 64.99?13.33), the social function(64.59?25.14 vs 69.41?22.70)and the self-health evaluation (71.18?13.73 vs 76.75?11.30).Conclusion Improvements of the cognitive function and the quality of life can be observed in the initial period of medication with lamotrigine in epilepsy patients.

Objective To investigate the effect of active vitamin D (VD) on macrophage M1 and M2 phenotype and its role in protecting podocyte impairment in diabetic nephropathy (DN).Methods Diabetes mellitus rats were established by intraperitoneal injection with streptozocin.Rats were randomly divided into four groups:normal-1 (NC-1,n=8),normal-2 (NC-2,n=8,normal rats treated with calcitriol 0.1 μg· kg-1 · d-1 by gavages),DN (n=24) and VD (n=24,DN+calcitriol 0.1 μg· kg-1 · d-1 by gavages).Blood glucose and body weight were assessed,and 24-hour urine was collected regularly.Blood and urine samples were taken for biochemical study,and kidney tissues were used for PAS staining to assess histological changes.Immunohistochemical staining was used to detect number of CD68 + macrophage.Western blotting was used to detect protein expressions of nephrin,podocin,CD68,M1 specific marker of inducible nitric oxide synthase (iNOS),TNF-α and M2 specific marker of CD163,arginase 1 (Arg-1),mannose receptor (MR).Results (1) In DN group,levels of BUN,Scr,urinary protein and glomerular mesangial matrix proliferation were significantly higher (P ＜ 0.05),and the expressions of nephrin,podocin were significantly decreased compared with NC groups (P ＜ 0.05).These above changes were significantly improved in VD group (P ＜ 0.05).(2)Number of CD68 + macrophage infiltration in DN group was increased in a time dependent manner compared with NC groups,which was significantly reduced in VD group (P ＜ 0.05).(3)To further definite M1 and M2 macrophage activation phenotype,the protein expressions of iNOS and TNF-α was increased in DN group at 8th,14th,18th weeks compared with NC groups (P ＜ 0.05),which were significantly decreased in VD group (P ＜ 0.05).Although,there were no significant difference of protein expressions of CD163,Arg-1 and MR between VD and DN group at both 8th and 14th week (P ＞ 0.05),the protein expressions of CD163,Arg-1 and MR were higher in VD group at 18th week than that in DN group (P ＜ 0.05),and the ratio of CD163/CD68 was also enhanced in VD group (P ＜0.05).(4)Moreover,the protein expression of iNOS was negatively correlated with expression of either nephrin or podocin (r =-0.707,P ＜ 0.01; r =-0.712,P ＜ 0.01),whereas the protein expression of CD163 was positively correlated with expression of either nephrin or podocin (r =0.627,P＜ 0.01; r=0.613,P ＜ 0.01).Conclusion Vitamin D can regulate macrophage phenotype,via inhibiting M 1 macrophage activation and enhancing M2 macrophage activation to protect podocyte impairment.

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.
