Objective To investigate the relationship of PTEN,Ki-67,type of credits of thymoma in WHO organization and Masaoka staging,and the significance of the biology's expression in thymoma.Methods The expression of PTEN and Ki-67 in 52 pieces of thymoma specimens was detected by the method of immunohistochemical SP.Results Positive expression rate of the 52 patients with thymoma was decreased gradually after WHO classification (8/10,10/14,6/12,4/11,0,0 and 10/13,12/20,6/16,0),Masaoka staging and PTEN.The difference were significant in statistics (λ2 =11.751,P =0.038 ; x2 =8.311,P =0.040).Positive expression rate of Ki-67 was gradually increased (1/10,6/14,6/12,8/11,2/3,2/2 and 3/13,9/20,10/16,3/3),the difference was also significant in statistics (x2 =11.231,P =0.047; x2 =7.904,P =0.048).Conclusions The positive expression rate of PTEN,Ki-67 are both related to clinical classification and staging closely.The detection to the positive expression rate of PTEN and Ki-67 can contribute to judging thymoma biological characteristics,thus,it will be helpful in diagnosing the thymoma,analyzing the degree of malignancy,invading and transferring ability.And then provide objective indicators for clinical diagnosis and treatment.

The mirror neuron system is an action observation-execution mechanism which plays an important role in many neurophysiologicalprocesses, such as action observation, action imitation, motor imagery and motor learning. It is an important neural mechanism of actionobservation therapy, motor imagery therapy, mirror therapy, virtual reality therapy and brain computer interface technology.

Objective To explore the clinical significance of the serum Epstein-Barr virus determined nuclear antigen 1 (EBNA1)/latent membrane protein 1 (LMP1) in patients with extranodal NK/T-cell lymphoma,nasal type (ENKL).Methods The serum EBNA1 and LMP1 were detected by realtime PCR in 36 ENKL patients hospitalized in Beijing Tongren Hospital from August 2010 to August 2013.Twenty healthy volunteers were recruited as controls.Results The median serum EBNA1 was 1.9 × 104 (ranged from 0 to 11.0 × 104) copies/μl in ENKL patients and 8.0 (ranged from 0 to 43.8) copies/μl in healthy volunteers.The median serum LMP1 was 3.9 × 103 (ranged from 118.3 to 24.0 × 103) copies/μl in ENKL patients and 3.3 (ranged from 0 to 33.3) copies/μl in healthy volunteers.Both EBNA1 and LMP1 were higher in ENKL patients than healthy volunteers (all P ＜ 0.01).The median EBNA1 and LMP1 in ENKL patients posttreatment were 1.0 × 103 (ranged from 0 to 2.0 × 103) copies/μl and 300.8(ranged from 0 to 825.7) copies/μl respectively,which were both significantly decreased than pretreatment (all P ＜ 0.05).The EBNA1 and LMP1 were decreased in effective treatment group versus ineffective treatment group (P ＜0.05).The serum EBNA1 and LMP1 were positively correlated with lactic dehydrogenase (LDH) level (r =0.364,0.546 ; P =0.040,0.012).Conclusions (1) The measurement of EBNA1/LMP1 may be useful in evaluating the therapeutic effect.(2)The serum EBNA1/LMP1 may reflect the tumor load in ENKL patients.

Objective To investigate clinical characteristics and risk factors in elderly patients with type 2 diabetes mellitus (T2DM) complicated with chronic kidney disease (CKD).Methods Two hundred and two T2DM patients aged ≥60 y admitted in Tongren Hospital from August 2009 to February 2012 were enrolled in the study,including 64 cases complicated with CKD (CKD group)and 138 cases without CKD (non-CKD group).Hemoglobin (Hgb),albumin (ALB),glycated hemoglobin A1C (HbA1 c),fasting plasma glucose(FBG),postprandial glucose (PBG),serum creatinine (Scr),blood urea nitrogen (BUN),uric acid (UA),total cholesterol (TC),triglyceride (TG),high densitylipoprotein (HDL-C),low density lipoprotein (LDL-C) were measured and ratio of urinary albumin to creatinine (UAER/CR) were calculated,ankle brachial index (ABI) and ambulatory blood pressure was examined.Results The duration of diabetes in CKD group was longer than that in non-CKD group [(13 ± 11) vs.(10 ± 7) y,t =2.35,P ＜ 0.05].Hgb and ALB in CKD group were lower than those in non-CKD group [(12.1 ± 1.7) vs.(13.3 ±1.3) g/L,(34.4±2.6) vs.(36.8 ±3.4) g/L,t=-5.73,-4.75,allP＜0.01]; UA,TG,24 h systolic blood pressure (SBP),24 h pulse pressure (PP)in CKD group were higher than those in non-CKD group [(367 ± 81) vs.(323 ± 74) μmol/L,(1.6 ± 0.9) vs.(1.3 ± 0.7) mmol/L,(133 ± 14) vs.(127±16)mmHg,(65 ±12) vs.(58 ±12)mmHg,t =3.82,2.50,2.47,3.68,all P＜0.1].The UAER/CR in CKD group and non-CKD group was 86.2 mg/g (24.6-374.8 mg/g) and 6.0 mg/g (3.6-17.8 mg/g),respectively (P ＜ 0.01) and ABI in CKD group and non-CKD group was 0.94 ± 0.18 and 1.03 ±0.18 (-2.78,P ＜0.05).There were no significant differences in FBG,PBG,HbA1c,TC,HDL-C andLDL-C between two groups(t =-2.02,1.47,1.48,-0.53,-1.20,-0.76,all P＞0.05).Logistic regression analysis showed that ALB,TG and UAER/CR were the independent risk factors of CKD in T2DM patients(OR:0.79,3.63 and 1.04,95％ CI:0.62-1.01,1.45-9.01 and 1.00-1.08).Spearman correlation analysis demonstrated that eGFR was positively associated with Hgb,ALB,ABI (r =0.38,0.33 and 0.28,all P ＜ 0.01),negatively associated with age,BUN,Cr,UA,TG,UAER/CR,24 hSBP and PP in all diabetes patients(r =-0.32,-0.63,-0.89,-0.34,-0.18,-0.65,-0.16 and -0.248,all P ＜0.01).Conclusions ALB,TG,UAER/CR are the independent risk factors of chronic kidney disease in elderly patients with type 2 diabetes mellitus.

Objective To study the route of branches of the internal iliac artery for presenting basic applied anatomy to be used in pelvic tumor diagnosis and interventional therapy through angiographic manifestations. Methods The branches of the internal iliac artery were studied by means of dissection on 45 adult cadavers(30 male, 12 female), including the origin, length, external diameter and bifurcation angle; and additionally angiographic characteristics of pelvic tumors in 42 cases together with normal ones of another 50 cases through bilateral selective internal iliac arteriography. Results①The angle between left and right common iliac artery was (58.9??7.3?),and that between the external and internal iliac artery was (27.6??5.3?). Iliolumbar artery and obturator artery were mainly originated from the main trunk of internal iliac artery and the distal portion (50%, 84.8%).②The external diameter of the branches of the internal iliac artery measured on cadavers was significantly smaller than that on patients alive. Conclusions Normal variations occur frequently in the origination, site of orifice and route of the middle and small branches of the internal iliac artery.

OBJECTIVE:To investigate the clinical efficacy and safety of amoxicillin sodium and clavulanate potassium com-bined with cranial mild-moderate hypothermia in the treatment of neonatal hypoxic-ischemic encephalopathy (HIE) complicating with pulmonary infection. METHODS:80 children with HIE complicating with pulmonary infection were randomly divided into ob-servation group(42 cases)and control group(38 cases). Control group received routine treatment under normal body temperature as lowering intracranial pressure,correcting acid-base balance,giving nutritional support and anticonvulsive treatment,and then was given amoxicillin sodium and clavulanate potassium 30 mg/kg intravenously,tid,more than 30 min each time,for consecutive 3 d. On the basis of control group,observation group was additionally given cranial mild-moderate hypothermia therapy:wearing cooling cap,at 10 ℃;keeping pharynx nasalis temperature at 34 ℃;keeping rectal temperature at 33-37 ℃;decreasing at rate of 1 ℃/h. They continued treatment for 3 d till body temperature decreased to 34.5 ℃;and then cooling cap was taken off to recover normal body temperature. Therapeutic efficacy of HIE and pulmonary infection were observed in 2 groups. NBNA score of 2 groups were recorded 1st,2nd and 4th week after birth,and the occurrence of ADR was observed. RESULTS:Total effective rate of HIE therapy (95.24% vs. 78.95%),cure rate of pulmonary infection (52.38% vs. 26.32%) and total effective rate (85.71% vs. 65.79%) in observation group were significantly higher than control group,with statistical significance (P<0.05). There was no statistical significance in NBNA score between 2 groups 1st week after birth(P>0.05). Compared to 1st week after birth,NBNA score were significantly improved 2nd and 4th week after birth,and the observation group were significantly higher than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Amoxicillin sodium and clavulanate potassium combined with cranial mild-moderate hypothermia is effec-tive for HIE complicating with pulmonary infection,and can effectively improve the prognosis of children with good safety.
