Objective To investigate changes in plasma levels of D-dimer in patients with prostate hyperplasia(BPH)complicat-ed with acute urinary retention(AUR),and to explore its clinical significance.Methods 102 cases of patients with prostate hyper-plasia complicated with acute urinary retention,treated in this hospital from July 2013 to December 2014,were selected and divided into the simple BPH group(56 cases)and BPH complicated with AUR(BPH+AUR)group.The plasma levels of D-dimer of these patients were detected and comparatively analysed.Results Compared with the simple BPH group,the plasma levels of D-dimer of patients in the BPH+AUR group was increased,had statistically significant difference.(P <0.01).Conclusion The plasma levels of D-dimer in patients with BPH complicated with AUR increase significantly,which indicates that patients are with secondary in-creased fibrinolytic activity.Measures should be taken to relieve urinary retention as soon as possible,so as to protect the vascular endothelial function of patients and reduce the incidence of complications.

Objective To evaluate the efficacy and safety of 131I-metaiodobenzylguanidine (131 I-MIBG) in treatment of malignant pheochromocytoma/malignant paraganglioma (MPHEO/MPGL).Methods The clinical data of 96 cases of MPHEO/MPGL (60/36) treated with 131I-MIBG between December 1998 and April 2014 were retrospectively reviewed.Among them,the malignant pheochromocytoma was found in 60 cases and malignant paraganglioma was found in 36 cases.Seventy-eight patients (81.2％)presented initially with hypertension,whereas 18 patients (18.8％) presented adrenal incidentaloma.Before 131I-MIBG treatment,24 h urinary norepinephrine was (409.5± 127.2) nmol,24 h urinary dopamine was (99.3±41.1) nmol,24 h urine adrenaline was (1 409.9±336.0) nmol.Before treatment,the compound iodine solution was given to each one.Then,all patients were given an initial course of 131I-MIBG therapy (5.55,7.40 GBq).Subsequent 131I-MIBG treatment (5.55,7.40 GBq) was undertaken every three to six months.The patients got symptomatic,hormonal or radiological response underwent sbsequent 131I-MIBG therapy (3.70,5.55 GBq) every year.All patients underwent clinical symptoms (headache,palpitate,sweating,hypertension),biochemical (24 h urine catecholamin) and radiological evaluation (CT/MRI) within 6 months to evaluate the efficacy and safety of 131I-MIBG treatment.Results After one to eleven sessions of 131 I-MIBG treatment,in total,266 doses of 131 I-MIBG were administered,average dose was 6.49 GBq.22.9％ of patients demonstrated radiological partial response (≥ 50％ reduction in tumor size) after first or repeated 131 I-MIBG treatment.Eleven cases (11.5％) achieved clinical complete response,41 cases (42.7％) achieved clinical partial response and 23 cases (24.0％) maintained the stable clinic symptoms.After treatment,24 h urinary norepinephrine (164.3±71.6) nmol and dopamine (49.7±24.7) nmol showed significantly decline,compared with those before treatment (P＜ 0.05).While,24 h urinary epinephrine (1 354.7±433.4) nmol had no obvious change (P＞0.05).No life-threatening adverse events were reported,but 2 MPGL patients developed transient leucopenia or thrombocytopenia after four and five times 131 I-MIBG treatment,respectively.Conclusions Treatment with repeated low dose 131I-MIBG is well tolerated and effective in controlling the progression and alleviating the clinical symptoms.The 131I-MIBG therapy is an effective and safe treatment modality for MPHEO/MPGL.

OBJECTIVE:To investigate the role of clinical pharmacists on drug therapy for acute exacerbations of chronic ob-structive pulmonary disease(AECOPD)patients with benign prostatic hyperplasia(BPH). METHODS:Clinical pharmacists partici-pated in drug therapy for a AECOPD patient with BPH. According to clinical guideline and relevant literatures,based on the history of disease,the characteristics of bronchodilators and the symptoms of acute urinary retention,it was suggested to stop taking Ip-ratropium bromide solution for inhalation but receive Finasteride capsules 5 mg,po,qd,to reduce prostate volume and improve ob-struction+Terazosin hydrochloride tablets 2 mg,po,qd,to relax urethral smooth muscle;the occurrence of ADR was monitored closely. Salmeterol xinafoate and fluticasone propionate powder for inhalation was suggested and medication guidance for patients af-ter discharge was given by clinical pharmacists. RESULTS:Physicians adopted some suggestions of clinical pharmacists. The pa-tient was stable and had no dysuria. The patient was allowed to leave the hospital with drugs. CONCLUSIONS:Rational use of bronchodilators is directly related to the remission of clinical symptoms and prognosis in AECOPD patients. In view of patient's dis-ease history,drug characteristics and clinical symptoms,clinical pharmacists point to possible risks of anticholinergics use,and as-sist physicians to formulate and adjust therapy plan so as to guarantee the safety and effectiveness of drug use.

Objective To establish the normal reference range for serum folate of healthy children in Guangzhou region.Methods Levels of serum folate of 1 860 healthy children (1 061 males and 799 females) and 129 adults (52 males and 77 females) living in Guangzhou region were examined by LK3000V Vitamin Analyzer.Then the data were analyzed with statistical methods.Results ①There was no statistical difference between boys and girls for levels of serum folate in every group defined by age (P＞0.05).②The levels of serum folate [median(P2.5,P97.5)] defined by age were as follows:9.39 (6.12,14.85) nmol/L for 0～1 year-old group,10.65 (6.05,16.52) nmol/L for 1.01～17 year-old group and 11.12 (6.3,17.51) nmol/L for the adult group.Statistical difference was found between any two groups of the three (P＜0.05).③No statistical correlation was found between age and the level of serum folate (r=0.039,P=0.09).Conclusion Reference range for serum folate for healthy children in Guangzhou region include two parts:6.12～ 14.85 nmol/L for 0～ 1 year-old group and 6.05～～16.52 nmol/L for 1.01～17 year-old group.

ObjectiveTo explore the possibility of repairing sciatic nerve gap of rats with artifical nerve graft.MethodsA novel artifical nerve guide was developed and used to suture the 15 milimeter long right sciatic nerve gap of 10 rats, other 7 rats were the control with the right sciatic nerve gap alone.2 and 4 monthes after operation, immunohistochemistry, Osmium staining, Bodian staining,motor end plate staining,WGA-HRP stain tracing have been done to observe the effect of repairing.Results2 months after operations, the sciatic nerve gap were repaired by the regeneration nerve.There was not evident inflammation in the defects.ConclusionsThe artifical nerve graft can induce the nerve to regenerate.

ObjectiveTo evaluate the biocompatibility of a kind of scaffolding material,Injured Nerve Regenerated Materid(INRM), which play the roles of regeneration of nerve after traumatic brain injury.MethodsINRM scaffolding material were transplanted into cortex of rats after traumatic injury.The brain coronal sections were stained for Nissel, astrocyte and microglia at 1 week, 1 month, and 2 months after injury.ResultsThe presence of INRM did not alter patterns of astrocyte compared with the control group (detected with antibodies against GFAP) at any time point; but decreased the expression of microglias (detected with antibodies against OX42) compared with the control group.ConclusionThe biomaterial INRM is well suited as a biocompatible scaffold material for the repair of brain injury in the brain.

Background: Psoriasis vulgaris is a chronic inflammatory skin disease which occur at any age. It can be clinically classified into two age-onset subtypes: early-onset psoriasis (EOP;＜40 years) and late-onset psoriasis (LOP; ≥40 years). More evidence showed EOP and LOP have different genetic architecture, notably the risk allele human leukocyte antigen (HLA)-C*06:02 located within the major histocompatibility complex (MHC) region, which was reported to be the outstanding variant associated with EOP. However, genetic structure of EOP and LOP have not been fully elucidated. Objective: To investigated HLA genetic heterogeneity between EOP and LOP in China. Methods: We first calculated the MHC-based heritability of EOP and LOP respectively.Then, we conducted a large-scale, stratified analysis including 7,097 EOP, 1,337 LOP patients, and 9,906 healthy controls by using MHC target sequencing data from a previousstudy. Results: We observed that HLA alleles collectively explained a larger heritability of EOP (27.4%) than LOP (11.3%).Further association analysis identified three independent loci (HLA-C*01:02, p=6.70×10−8 ; HLA-A amino acid position 9, p=3.27×10−17 ; and HLA-A amino acid position 161, p=5.75×10−10 ) that confer specific susceptibility to EOP. Our data also confirmed HLA-C*06:02 as an independent psoriasis-associated variant, contributing a higher degree of risk to EOP than LOP. Moreover, case-case analysis confirmed that HLA-C*06:02-positive psoriasis patients have earlier onset. Conclusion Our analysis indicating that different genetic background underlie the EOP and LOP. We believe these findings will serve to predict psoriasis risk in the future and facilitate clinical decision.

ObjectiveTo study the effect the chitosan tube combined with the bio active carrier system on inducing nerve axon regeneration of rats with spinal cord injury.Methods50 female Wister rats were characterized by the right spinal cord hemisections at the seventh and eighth thoracic segment to make the model of spinal cord hemisection. The chitosan tube serving as a regenerative loculus was implanted in the defect location of the experimental models.In the experimental group,the bio active carrier system was injected into the chitosan tube,while in control group injected nothing.The drua was sutured to restore cerebrospinal fluid circulation.Results6 months and 12 months after operation,the regenerative nerve axon had passed the defect area of spinal cord in the experiment group. According to WGA-HRP anterograde axonal tracing study, some TMB-positive axons were observed in the distal graft host interface,and came into the host environment. TEM-ultrastructure indicate some neonate synapse, myelinated nerve fibers.In the control group,few regenerative axon could be seen, there was no regenerative axon pass the middle of the tube.ConclusionsThe chitosan tube in which the bio active carrier system was injected can induce the spinal cord nerve axon regeneration.

Liver transplantation is a vital treatment for end-stage liver disease. However, the shortage of donor livers has limited the development of liver transplantation. How to expand the source of donor livers has become a challenge in the academic community. In recent years, the proportion of donors with non-alcoholic fatty liver disease (NAFLD) has been increased. Rational use of steatotic donor livers is a feasible approach to expand the donor pool. Cold ischemia injury during donor liver preservation before liver transplantation increases the risk of postoperative organ dysfunction. Therefore, it is of significance to unravel the mechanism and intervention measures of cold ischemia injury of steatotic donor livers. Cold ischemia injury of steatotic donor livers is characterized as the damage of mitochondria, lysosomes and endoplasmic reticulum at the organelle level, and up-regulated expression of adenosine monphosphate activated protein kinase (AMPK), aldehyde dehydrogenase 2 (ALDH2) and heme oxygenase (HO)-1 at the protein level. In this article, the research progresses on cold ischemia injury of steatotic donor livers and relevant intervention measures were reviewed.

Objective: To investigate the effect of gross motor skills on physical activity of children aged 3-6 years, and to provide basis for children’s health behavior intervention. Methods: A total of 332 young children in Shanghai Xiangyin kindergarten were selected as survey objects. The development of gross movements of young children was measured by TGMD-2. Caregivers reported children’s physical activity using the International Physical Activity Questionnaire (IPAQ-SF). Results: The development level of gross movements of children aged 3-6 in Shanghai was relatively low(54.76±13.86). The physical activity of children was mainly light-intensity physical activity, and the daily moderate-to-vigorous intensity physical activity time was (58.62±52.73) minutes every day. Locomotor skills had the greatest effect on children’s VPA (β=0.19) and TPA(β=0.12), with a contribution rate of 3.3% and 1.1%, respectively; Object control skills has the greatest effect on children’s MVPA (β=0.17) and MPA (β=0.12) had the largest effect(P<0.05), with contribution rates of 2.5% and 1.2%, respectively. The relationship between gross motor skills and physical activity had nothing to do with gender and age. Conclusion Children’s gross motor skills in the 3-6 year-old population should be improved and may be an effective way to promote physical activity.
