Objective To observe the response of and recurrence in patients with localized eczema after treatment with topical glucocorticoid alone or in combination with topical antibacterials.Methods Totally,217 outpatients with acute or subacute localized eczema were enrolled and randomly classified into two groups to be treated with topical corticosteroids combined with mupirocin cream (experiment group,n=191) or topical corticosteroids alone (control group,n =190) for two weeks.The patients who were cured at the end of the 2-week treatment were followed for 13 weeks for the observation of recurrence.Chi-square test and Student's t test were conducted to compare the cure and recurrence rates between different groups of patients.Results After two weeks of treatment,the cure rate in the experiment group was significantly higher than that in the control group (80.6％ vs.64.8％,x2 =6.576,P =0.01).Increased cure rate was also observed in patients with acute and subacute eczema receiving glucocorticoidCaspase14antibiotic combination therapy compared with those receiving corticosteroids alone.During the 13Caspase14week follow up,a lower recurrence rate was noted in the experiment group compared with the control group (15.6％ vs.33.8％,x2 =6.455,P ＜ 0.05).Further more,the patients experiencing relapse of eczema showed a higher proportion of hand eczema cases (29.4％ vs.13.0％,x2 =4.982,P ＜ 0.05)compared with those without relapse.Adverse reaction was mild in these patients,and no statistical difference was observed between the experiment group and control group (5.71％ vs.4.46％,x2 =0.176,P ＞ 0.05).Conclusion The combination with topical antibacterials may enhance the therapeutic effect of topical glucocorticoids on and reduce the recurrence of localized eczema.

Objective To research the applications of resting-state functional MRI in conjunction with voxel-based morphometry on cerebral functions and structures in patients with schizophrenia. Methods Thirty-two patients with schizophrenia and 32 healthy people underwent resting state functional magnetic resonance imaging (Rs-fMRI)and sagittal scanning T1WI with 3D FFE Pulse Sequence. Rest1.8 software was applied to calculate the differences of amplitude of standardized low-frequency fluctuation(ALFF)between the two groups,then the voxel-based morphometry(VBM)data of abnormal brain regions were evaluated to compare the differences of grey matter intensity. Finally,combining with ALEF and VBM,we explored the changes of cerebral functions and structures. Results As compared to the control group ,the ALFF-elevated regions were the right putamen ,the left orbital frontal cortex extending to the left putamen and left dorsal-lateral superior frontal gyrus;the ALFF-decreased regions were the right inferior tempotalgyrus,the left posterior cingulated gyrus and the left angular gyrus(P<0.05). No elevated regions of grey matter intensity were found in the patient group. Conclusions Extensive abnormal active regions of the brain under resting state could be found in patients with schizophrenia ,the grey matter intensity of abnormal regions also decreased generally. They are in accordance with the glutamate-hypothesis of schizophrenia ,which involves extensive impairments of neurons ,disorders of neurotransmitter′s circulations and balances.

To improve the water solubility of daidzein, solid inclusion complexes of daidzein with two amino-modified β-cyclodextrins (ACDs), i.e., mono-6-amino-6-deoxy-β-cyclodextrin (NCD) and mono-6-ethylenediamino-6-deoxy-β-cyclodextrin (ENCD), were prepared by the saturated solution method in water under the preparation conditions as follows: the ratio of daidzein/ACD was 3∶1 and the stirring time was 72 h (83% and 67% yields, respectively).The formation of two inclusion complexes was confirmed by x-ray diffractometry (XRD) and themogravimetric (TG) analysis.The inclusion stoichiometry of the inclusion complexes was 1∶1 from the Job plot and their complexation stability constants (KS) were 899.2 and 203.8 L/mol from fluorescence titration, respectively.After formation of inclusion complexes with NCD and ENCD, the water solubility of daidzein was dramatically raised from 8.31 μg/mL to 15.2 and 13.2 mg/mL at 25℃, increasing by 1800-fold and 1500-fold.

Objective To summarize the experience of organ donation after citizen' s death during the novel coronavirus pneumonia (COVID-19) epidemic. Methods Eleven cases of potential donors of organ donation after citizen' s death during the COVID-19 epidemic were retrospectively analyzed, and the workflow and key points of infectionprevention and control were summarized. Results Among 11 cases of potential donors, 6 cases failed to implement organ donation. Five donors who were successfully performed organ donation had no respiratory symptoms before the onset of encephalopathy. CT scan of the lungs upon the onset of encephalopathy showed that one case was diagnosed with aspiration pneumonia, and the remaining four cases obtained negative results. During hospitalization, all of the 5 donors showed fever symptom and repeated chest CT scan detected lung inflammation. Bronchoalveolar lavage fluid or blood samples tested for novel coronavirus nucleic acids were all negative. No confirmed or suspected cases appeared among all staff and recipients who were in close contact with organ donors. Conclusions Targeted formulation of the workflow and prevention and control measures, in combination with selection and implementation of infection risk classification can effectivelyreduce the risk of COVID-19 infection and carry out organ donation after citizen' s death in a safe and organized manner.

Methods This is a retrospective study including 40 eyes of 23 VKH patients. The eyes were divided into 2 groups according to the results of fluorescein fundus angiography (FFA). The discs with hyperfluorescence but no leakage were in mild optic disc edema group (group A, 13 patients and 25 eyes), and the discs with hyperfluorescence and leakage were in severe optic disc edema group (group B, 10 patients and 15 eyes). The patients were significantly older in group B than in group A (t=-2.17, P<0.05). The differences of gender, diseased time (t=-1.67) and corrected visual acuity (t=-0.76) between 2 groups were not significant (P>0.05). Eighty eyes of 46 normal healthy subjects, matching group A and group B with age and gender, were divided into group C (26 subjects and 50 eyes) and group D (20 subjects and 30 eyes) respectively.All subjects underwent three dimensional optical coherence tomography examinations.

Results The disc area, disc cup area and rim area were bigger, the thickness of mean CP-RNFL and the nasal and temporal quadrants of CP-RNFL were thicker in group A than those in group C (P<0.05). The disc area and rim area were bigger, the thickness of mean CP-RNFL and the nasal, superior, temporal and inferior quadrant of CP-RNFL were thicker, C/D area ratio and C/D diameter ratio were smaller in group B than those in group D (P<0.05). The disc area was bigger, disc cup area, C/D area ratio and C/D diameter ratio were smaller, the thickness of mean CP-RNFL and the nasal , superior and inferior quadrants of CP-RNFL were thicker in group B than those in group A (P<0.05). Conclusions Acute VKH uveitis with mild optic disc edema has thicker CP-RNFL in the nasal and temporal quadrants; with severe optic disc edema has thicker CP-RNFL in all 4 quadrants. Acute VKH uveitis also has smaller C/D area ratio and C/D diameter ratio.
