After ig and iv 3H-berberine in rabbits, the plasma radioactivity-time cure was found to be 2-compartment open model. The pharma-cokinetic parameters were: T1/2B 35 .3?1 .3h ( ig ) and 35.8 ? 2.0h (iv), Vd 20 ?3 L/kg(ig) & 22.1?1.7 L/kg ( iv ) . 3H-berberine was rapidly absorbed & taken up by various organs . The highest radioactivity was found in lung, followed by liver, spleen & heart. The rate of binding with plasma protein was 38 ? 3 % . In 6 d cumulative excretion of radioactivity was 73% of total dose in urine & 10.9% in fe-ces . 3H-berberine was excreted mainly in unchanged form, as measured by TLC & liquid scintillation counting in urine & bile.

The efficacy and safety of Saccharomyces boulardii in treatment of candida esophagitis was investigated by a single center, prospective, open label and non-inferiority trial.Eighty nine patients with candida esophagitis attending in Shanxi Provincial People′s Hospital during April 2015 to March 2016 were randomly divided into Saccharomyces boulardii group (45 cases) and nystatin group (44 cases), and oral Saccharomyces boulardii powder and Nystatin tablets were given to two groups respectively.The curative effect was evaluated by gastroscopy after the treatment.The results showed that the cure rate of Saccharomyces boulardii group and nystatin group was 68.9%(31/45)and 63.6%(28/44), and the Saccharomyces boulardii was noi inferior to nystatin (x2=3.027, P<0.05).Chi-square test showed that there was no significant difference in effective rate between two groups [91.1%(41/45)vs.93.2%(41/44), x2<0.001, P>0.05].The incidence of adverse reactions in boulardii group was significantly lower than that in nystatin group [2.2%(1/45) vs.22.7%(10/44), x2=8.636, P<0.05].The study suggests that the cure rate of Saccharomyces boulardii is not inferior to nystatin in treatment of candida esophagitis, while the incidence of adverse reactions of Saccharomyces boulardii is lower.

ObjectiveTo study the outcome of 3 kinds of disabled children. Methods269 disabled children found in 2004 Beijing Disabled Children Sampling, which including 237 children with mental retarded disability, 57 with physical disability and 26 with psychological disability, were followed up in 2007. Results52.32% of mental disabled children, 8.77% of physical disabled, and 15.38% of psychological disabled children would not be seen as "disability" any longer. ConclusionThe disability before 6 years old is a kind of developmental disability, which may be recovery as development.

Objective To investigate the clinical and magnetic resonance imaging(MRI)features of Trousseau's syndrome(TS)with acute cerebral infarction,so as to improve the accuracy of diagnosis of this disease.Methods Fifty-three cases of TS with clinically confirmed acute multiple brain infarction(AMBI)and 52 cases of TS without AMBI were enrolled,and the head MRI,primary tumor imaging and clinical data of the patients were retrospectively analyzed.The clinical and MRI features and thrombus types of the 2 groups were compared.Results There were significant differences in the types of thrombus between the 2 groups(P=0.001),while there were no significant differences in gender,age,whether they had hypertension,diabetes mellitus,hyperlipidemia,basic cardiovascular diseases or not,preventive medication use,abnormal coagulation function,or D-dimer level(all P＞0.05).The primary tumor type of 105 TS patients was mainly adenocarcinoma.MRI of the head of 53 TS with AMBI patients showed that the distribution area of acute and subacute infarct foci was bilateral anterior circulation in 16 cases,bilateral anterior circulation+bilateral posterior circulation in 17 cases,bilateral anterior circulation+unilateral posterior circulation in 4 cases,and unilateral anterior circulation in 16 cases.Enhancement scans were performed in 23 cases,of which 11 cases showed some infarct foci appeared enhanced and 12 cases did not show significant enhancement.Twenty-eight cases did not show meaningful stenosis of the cerebral arteries,4 cases showed stenosis occlusion of the cerebral arteries,and all lesions did not conform to cerebrovascular distribution.Twenty-four cases of arterial thrombosis(10 cases of carotid artery thrombosis,3 cases of lower-extremity arterial thrombosis,5 cases of cerebral arterial ring thrombosis,1 cases of pulmonary artery thrombosis,1 case of renal artery thrombosis,and 4 cases of subclavian artery thrombosis)and 3 cases of venous thrombosis(deep vein thrombosis of the lower extremities)were found among the patients with visualized thrombosis.The D-dimer level was increased in different degrees.Conclusion Multiple speckled and patchy acute anterior and posterior cerebral infarcts involving bilateral cerebral and cerebellar cortex,subcortical areas and hemi-oval centers with lesions not conforming to cerebrovascular distribution are the characteristic manifestations of MRI of the head in the combination of malignant tumors with TS.Adenocarcinoma is the main malignant tumor,and the combination of D-dimer index can improve the accuracy of diagnosis.

Blinding is an important method to control the measure bias in clinical trials.As a complex and invasive intervention,acupuncture has more difficulty in blinding implementation compared to drugs and has a higher risk of unblinding breakage.This article provides an overview of the blinding in acupuncture clinical study and summarized the key aspects,including:there is no standard for the application and reporting of sham acupuncture design and blinding measures,appropriate sham acupuncture devices still need to be developed,currently there are no effective methods of operator blinding,blinding assessment has not been given due attention,sham acupuncture design should be standardized and reported.Researchers should conduct further studies to address critical questions and challenges to provide methodological support to improve and promote the quality of acupuncture clinical research.

Objective To investigate the changes in the expression of complement C3,high mobility group protein B1(HMGB1),and glutathione peroxidase 4(GPX4)in brain tissue at different time points after cerebral ischemia-reperfusion injury in rats.Methods A total 72 SPF male SD rats were randomly divided into a sham operation group(36 rats)and a model group(36 rats).A rat model of middle cerebral artery occlusion was established using thread occlusion,and then the rats from the model group were further assigned into 4 subgroups with reperfusion time for 3,6 and 24 h and 3 d,respectively,with 9 rats in each subgroup.Zea Longa scoring was used to assess neu-rological function.R2StarMap imaging,diffusion-weighted imaging(DWI),T1 weighted imaging,and T2 weighted imaging were performed on all the rats.The volume of abnormal DWI signals were detected and the volume of cerebral infarction was measured.The original R2StarMap images were post-processed to generate R2*pseudo color images,and then the R2*values of the areas with blood supply from bilateral middle cerebral artery were measured to detect iron deposition in the brain.The protein expression of C3,HMGB1,and GPX4 was detected by Western blotting.Results The sham operation group showed no neurological damage,while the model group had a significant increase in neurological function scores at 3,6 and 24 h and 3 d after modeling when compared to the sham surgery group(P＜0.05).While the size of right cerebral infarct was in-creased significantly at 3,6 and 24 h and 3 d in the rats of the model group(P＜0.05).The R2*value of the area with blood supply from the right middle cerebral artery in the model group was significantly higher than that in the left side at 3,6 and 24 h and 3 d(P＜0.05,P＜0.01),and it was also obviously higher than that in the right side of the sham operation group at these time points(P＜0.05,P＜0.01).The R2*ratio of the right and left blood supply areas in the model group at 3,6 and 24 h and 3 d was also statistically higher than that in the sham operation group at corresponding time points(1.82±0.82 vs 1.12±0.31,P＜0.05;1.31±0.26 vs 1.04±0.14,P＜0.05;1.94±0.74 vs 1.06±0.10,P＜0.01;1.99±0.39 vs 1.02±0.11,P＜0.01).Compared with the sham operation group,the expression levels of C3 and HMGB1 was significantly increased in the model group at 3,6 and 24 h and 3 d,while that of GPX4 was notably reduced(P＜0.01).Conclu-sion Cerebral ischemia-reperfusion injury impairs the neurological function of rats and signifi-cantly affects the cerebral expression of complement C3,HMGB1,and GPX4.
