Objective To analyze quantitatively two-dimensional sonography of bladder cancer and clot with integrated backscatter(IBS) to evaluate its applied value in differential diagnosis of ladder cancer and clot.(Methods The IBS) and IBS% were measured in 32 patients with bladder cancer and 18 patients with bladder clot.(Results There were) significant differences of average image intensity(AII),peak to peak intensity(PPI) and standard deviation of image intensity(SDI) between bladder cancer and clot(P

Objective To detect human papilloma virus (HPV) and to determine its genotype in children with condyloma acuminatum (CA) in Weifang city,Shandong province.Methods Swab specimens were collected from the surface of lesions of 24 children with CA.PCR/flow-through hybridization assay was performed to detect HPV and determine its genotypes in these specimens.Results Among the 24 specimens,95.8％ (23/24) were positive for HPV.Of the HPV-positive specimens,87.0％ (20/23) harbored single type of HPV,and 13.0％ (3/23) multiple types of HPV.The most common genotype was HPV6(9/23),followed by HPV16 (6/23),HPV11 (5/23),HPV58 (3/23),HPV18 (2/23),and HPV53 (1/23).Conclusions HPV 6,16,11,58 and 18 prevail in children patients with CA in Weifang city,Shandong province.Additionally,the HPV genotypes in children patients are similar to those in their close contacts.

Triggering receptor expressed on myeloid cells-1 ( TREM-1 ) is one of immunoglobulin superfamilies found recently.TREM-1 is a crucial molecule for the triggering and amplification of inflammatory response and promote the reduction of in anti-inflammatory factor by crosslinking reaction with its ligand after being activated,or increasing the level of transcription factor.This study shows that TREM-1 may be claimed as a marker of infection,and the blockade of TREM-1 may be a new approach to inflammatory diseases.This study summarizes its structure,signal transduction,expression,accommodation and clinical application.

Peanuts, corn and other food products are prone to aflatoxins (AF). AF was listed as a human carcinogen by the International Agency for Research on Cancer (IARC), especially aflatoxin B1 (AFB1), as it is considered the most prevalent and toxic. China is a big peanut producer, so carrying out pollution investigation and risk assessment in peanuts and their products is crucial to formulate prevention measures, protect export trade and maintain health. This paper summarizes the AF pollution of peanuts and their products in the Huang-Huai-Hai Basin, Yangtze River Basin, Southeast Coast and Northeast region of China from 2015 to 2021, and the application of dietary AF exposure risk assessment methods, providing a basis for strengthening the supervision of AF pollution in peanuts and their products, and ensuring food safety.

Objective To investigate the change of heart rate turbulence in patients with chronic heart failure and relationship to age、LVEF、LVED、heart rate before ventricular premature complex (VPC)、coupling interval、compensatory interval、the number and origin of VPC.Methods HRT was measured in 30 CHF patients and 30 healthy controls.HRT onset and slope were measured by the original definitions using Holter records and compared with the clinical factors.Results The HRT TS was significantly lower in patients wtih heart failure than in control (3.17?2.03vs9.64?6.47,P

Objective To evaluate the ability of force control of elbow and shoulder during isometric contraction in patients with chronic stroke. Methods From January to December, 2015, 22 chronic stroke patients and 12 healthy people were measured the maximum force dur-ing shoulder abduction/adduction and elbow flexion/extension with instrument for measuring force of upper extremity. The coefficient of variation was calculated. Results The maximum force was less in the patients than in the healthy controls (t>2.349, P<0.05), and the coeffi-cient of variation increased (t>1.974, P<0.05), except those of elbow extension. Conclusion The force measure and the coefficient of varia-tion can reflect the force control in shoulder and elbow motion in stroke patients.

[Objective]To investigate the related risk factors of unstable plaques in extracranial carotid arteries in patients with ischemic cerebrovascular diseases(ICVD).[Methods] Two hundred and eight ICVD patients were enrolled and plaques in extracranial carotid arteries were detected by c(a)rotid color ultrasound.All the patients were divided into unstable plaque group(75 cases)and stable plaque group (133 cases)according to the ultrasound performance.Related disease history and the traditional risk factors of ICVD were recorded.The risk factors with statistical significance were screened out by univariate nonconditional Logistic regression analysis,and then the independent risk factors of unstable plaques in extracnmial carotid arteries were analyzed by multivariate non-conditional Logistic regression analysis.[Results]Univariate non-conditional Logistic regression analysis showed that male,history of hypertension,history of diabetes,smoking were positively correlated with the formation of unstable plaques in extracranial carotid arteries(P＜0.01 or ＜0.05).High density lipoprotein cholesterol(HDL-C)was negatively correlated with the formation of unstable plaques in extracranial carotid arteries(P＜0.01).There were no statistical significance in history of coronary heart disease,law of life,family history of hypertension,drinking,family history of stroke and low density lipoprotein cholesterol between two groups(p ＞0.05).Multivariate non-conditional Logistic regression analysis showed that male,history of hypertension,history of diabetes and smoking were the independent risk factors of the formation of unstable plaques in ex tracranial carotid arteries (OR =2.33,7.16,6.15,2.28,respectively,P＜0.01).And HDL-C was the protection factor of the formation of unstable plaques in extracranial carotid arteries(OR=0.84,P ＜ 0.01).[Conclusions] The independent risk factors of the formation of unstable plaques in extracranial carotid arteries in patients with ICVD are male,history of hypertension,history of diabetes and smoking.And HDL-C is the protection factor of the formation of unstable plaques in extracranial carotid arteries in patients with ICVD.It has important significance to take out necessary intervention for patients with risk factors.

Though lack of definite evidences,closed suction drainage after arthroplasty is routinely employed by the majority of orthopaedic surgeons with the aim of preventing the formation of wound haematoma,reducing delayed wound healing and the risk of deep infection.But the optimal time to remove drains is controversial.The usual time to remove drains is 48~72 h after operation when the volume of drains is less than 50ml within 24 h.But some scholars find that the time of draining more than 24 h increases the risk of wound infection.This paper reviews the literature of draining time,and concludes that the optimal time to remove drains is 24 h after the primary arthroplasty.
