Objective To observe the clinical efficacy of transcutaneous electric acupoint stimulation in intervening early-stage swelling limb after breast cancer operation.Method A hundred patients undergone radical mastectomy for breast cancer were divided into a treatment group and a control group, 50 cases in each group. The control group was intervened by ordinary post-operative nursing, while the treatment group was additionally given transcutaneous electric acupoint stimulation. By measuring the circumference of both upper arms, the incidence rate and degree of swelling arm in 2 weeks after operation were compared, meanwhile, the accompanied symptoms such as tightness of skin, pain in upper limb, numbness in upper limb, and heaviness of upper limb were observed.Result The occurrence rate of abnormal upper-limb sensations was 22.0% in the treatment group versus 84.0% in the control group, and the difference was statistically significant (P<0.01). The occurrence rate of upper-limb swelling was 4.0% in the treatment group, versus 24.0% in the control group, and the difference was statistically significant (P<0.01). Conclusion Transcutaneous electric acupoint stimulation can effectively prevent and release the early-stage upper-limb swelling after breast cancer surgery.

Objective To evaluate renal vascular damage (RVLs) and detect the expression of miR-145 in children with lupus nephritis (LN).Methods Clinical data of 41 cases of LN diagnosed by renal biopsy from the children with systemic lupus erythematosus (SLE) were collected. Glomerular damage score and RVLs were evaluated. The children were divided into groups according to RVLs score and pathological pattern. In situ hybridization was performed to detect the expression of miR-145 in kidney blood vessel. Differences in RVLs, miR-145 expression in the renal blood vessels and glomerular damage score were observed among the groups with different renal pathological pattern. Differences in clinical parameters, glomerular damage score and miR-145 expression in the renal blood vessels were investigated among groups with different RVLs. Results Among the groups with different pathological pattern, there was no difference in RVLs (P>?0.05) while signiifcant different were found in the expression of miR-145 and glomerular damage score (P??0.05) while a statistical different was found in the expression of miR-145 (P?

Objective: The effect of oil of Hippophae rhamnoides (OHR) supplements on sGOT,metabolism of free radical and ultrastructure of myocardium was observed in mice.Methods: 70 male ICR mice were randomly divided into six groups: sedentary control group (SCG), sedentary+OHR group (SHG), immediately after exhaustive exercise in control group (IEC) and in OHR group (IEO), 24 hours recovery after exhaustive exercise in control group (REC) and in OHR group (REO). After 6 w swimming program with gradually increasing intensity, these mice carried out an exhaustive swimming before sacrifice. Serum GOT, SOD and MDA in myocardium were measured and the changes of ultrastructure of myocardium were observed by transmission electron microscope (TEM). Results: 1) Serum GOT was significantly different among these groups except between SCG and SHG, IEC and REC. 2) SOD was significantly different among the above groups except between SCG and SHG, IEO and REO. 3) The concentration of MDA was significantly different among the above groups except between IEC and IEO, REC and REO. 4) The integrity of mitochondrion, rough surfaced endoplasmic reticulum and myofilament in myocardium was better in OHR groups than in control groups and the pathological tendency of these ultrastructures was lighter in OHR groups compared with control groups. Conclusion: OHR supplementation can reduce the damage of myocardium caused by exercise and enhance antioxidative status of myocardium; OHR supplementation can protect the ultrastructure of myocardium.

METHODS: The percentage of GR? positive staining peripheral blood mononuclear cells (PBMC) and the quantity of nuclear protein of GR? in PBMC were detected by immunocytochemistry and Western blotting assay, respectively. The effect of sera isolated from children with GC-resistant INS on GR? expression was examined by cell culture in vitro . RESULTS: The number of GR? positive staining PBMC and the quantity of nuclear protein of GR? in children with GC-resistant INS were significantly higher than those in patients with GC-sensitive INS ( P

Objective:To analyze the podocalyxin (PCX) expression in the kidney and the number of urinary podocytes in different pathological grades of Henoch-Sch(o)nlein purpura nephritis (HSPN),and to determine whether the number of urinary podocytes reflects the renal damage in HSPN.Methods:Fifty-six children diagnosed with HSPN in our hospital were enrolled in the study and classified into 4 groups by renal pathology:grade Ⅱ (Ⅱa+Ⅱb) (n=10),grade Ⅲ (Ⅲa+Ⅲb) (n=21),grade Ⅳ (n=16),and grade Ⅴ (n=9).Four kidney autopsy specimens without histomorphologic lesions and 8 urine samples from healthy children served as controls.With immunofluorescence assay,the PCX expression in 4 normal renal tissues and in the renal tissues of the 56 HSPN children was detected and quantitatively analyzed.Positive rate and the number of urinary podocytes were detected in the 8 healthy children and 56 HSPN children.Results:In the renal tissues of the normal control group and grade Ⅱ (Ⅱa+Ⅱb) HSPN group,the PCX expression was complete.The percentage of the PCX positive area out of the total glomerular area in the renal tissues of 2 groups had no significant difference (P＞0.05).In the renal tissues of grade Ⅲ (Ⅲa+Ⅲb),Ⅳ,and Ⅴ HSPN groups,the PCX expression showed various degrees of loss,decreasing in turn from grade Ⅱ (Ⅱa+Ⅱb),Ⅲ (Ⅲa+Ⅲb),Ⅳ to Ⅴ,with significant differences between each group (P＜0.01).For HSPN with grade Ⅲ (Ⅲa+Ⅲb) or higher,positive PCX expression was found in the urine,suggesting the presence of enough podocytes in the urine.The percentage of fluorescence positive area out of the total glomerular area of PCX in the renal tissues was negatively correlated with the total number of urinary podocytes (r=-0.637,P＜0.01).Conclusion:Podocyte injury plays a certain role in the pathological progression of HSPN.The urinary detection ofpodocytes can reflect the degrees of pathological damage in HSPN.

Objective To explore the feasibility of DSCT dual-energy technique in pulmonary mass lesions.Methods A total of 100 patients with pulmonary masses underwent conventional plain CT scan and dual-energy enhanced CT scan.The virtual non-contrast (VNC) images were obtained at post-processing workstation.The mean CT value,enhancement value,signal to noise ratio (SNR),image quality and radiation dose of pulmonary masses were compared between the two scan techniques using F or t test and the detectability of lesions was compared using Wilcoxon test. Results There was no statistically significant difference among VNC ( A ) ( 32.89 ± 12.58 ) HU,VNC (S) ( 30.86 ± 9.60) HU and conventional plain images (35.89 ± 9.99 ) HU in mean CT value of mass ( F =2.08,P ＞ 0.05 ).There was statistically significant difference among VNC ( A ) ( 3.29 ± 1.45 ),VNC (S) ( 3.93 ± 1.49 ) and conventional plain image (4.61 ± 1.50) in SNR ( F =6.01,P ＜ 0.05 ),which of conventional plain scan was higher than that of VNC.The enhancement value of mass in conventional enhanced scan(60.74 ± 13.9)HU and distribution of iodine from VNC (A) ( 58.26 ± 31.99 ) HU was no statistically significant difference ( t =0.48,P ＞ 0.05 ),but there was a significant difference between conventional enhanced scan (56.51 ± 17.94 ) HU and distribution of iodine from VNC (S) (52.65 ± 16.78 ) HU (t =4.45,P ＜ 0.05 ).There was no statistically significant difference among conventional plain scan ( 4.69 ± 0.06 ) and VN C ( A ) ( 4.60 ± 0.09 ),VNC (S)(4.61 ±0.11 ) in image quality at mediastinal window ( F =3.014,P ＞ 0.05 ).The appearance,size,internal features of mass (such as necrosis,calcification and cavity) were showed the same in conventional plain scan,VNC (A) and VNC (S).Of 41 patients with hilar mass,18 patients were found to have lobular and segmental perfusion decrease or defect. Perfusion defect area was found in 59 patients with peripheral lung mass. The radiation dose of dual-energy enhanced scan was lower than that of conventional scan.Conclusion The virtual non-contrast,distribution of iodine and pulmonary virtual perfusion images can be obtained by DSCT dual-energy technique in one scan,which has a potential clinical value in the thorax.

Objective To investigate the characteristics of coronary's pathological changes in patients with impaired glucose tolerance. Methods Four-hundred and ninety patients who were suspected with ischemic chest pain were divided into three groups according to their OGTT results: (1) IGT group: n = 161,(2) 12DM group:n = 159, (3) NGT group: n = 170. Serum levels of triglyceride (TG) , total cholesterol (TC) , highdensity lipoprotein cholesterol (HDL-C) , low-density lipoprotein cholesterol (LDL-C) and high sensitive Creactive protein (hs-CRP) were detected, their body mass indexes (BMI) were calculated. General clinical information (including gender, age, history of smoking, history of hypertension) were collected. All the CAG results were analyzed and Gensini scores were assessed as well. Results The TG levels in the T2DM group and IGT group ([2. 41 ± 1.70] mmol/L and [2. 26 ± 1. 20] mmol/L) were significantly higher than that of the NGT group (1.95 ± 1.14) mmol/L, the differences were significant (t=0.4610,0.3124, P<0. 01 and 0.05,respectively),whereas there was no significant difference between the IGT group and T2DM group (P >0.05);No significant difference was found among the three groups about TC, HDL-C, LDL-C levels (either P > 0.05). The levels of hs-CRP in T2DM group ([2. 38 ± 1. 76] mg/L and IGT group [2. 33 ± 2. 03] mg/L) were higher compared with the NGT group ([1. 54 ± 1. 32] mg/L), the differences were significant (t = 0. 8391,0. 7815, Ps < 0. 01), whereas there was no significant difference between the IGT group and T2 DM group (P >0.05). BMIs of the IGT group ([25.50 ± 3.04]kg/m2) and T2DM group ([26.09 ± 2.86]kg/m2) were higher than that of the NGT group ([24. 70 ± 3. 27] kg/m2), the differences were significant (t = 0. 8063,1. 3947, P<0. 05 and <0.01, respectively),whereas no significant difference was found between the T2DM group and IGT group (P > 0. 05). The incidence of single coronary pathological changes was 44.7% in the NGT group,it was higher than that of the IGT group (23. 6%) and T2DM group (18. 9%) (x2 = 16. 310,25. 116,Ps < 0. 05), whereas there was no significant difference between the IGT group' and T2DM group (P > 0. 05);The incidences of 2 branches pathological changes in the T2DM group (37. 1%) and IGT group (39. 8%) were higher compared with NGT group (23. 5%) ,the differences were significant (x2 =1. 200,10. 099,Ps <0. 05),whereas there was no significant difference between the IGT group and T2DM group (P >0. 05) ;The incidences of 3 vessels pathological changes in the T2DM group (40.9%) and IGT group (33. 5%) were higher than that of the NGT group (20. 0%) , the differences were significant (x2 = 7. 767,17. 028, Ps < 0.05), there was no significant difference between the IGT group and T2DM group (P > 0. 05). The incidence of subtotal or total occlusion of the T2DM group and IGT group were 22. 6% and 18.0% respectively,both were higher than that of the NGT group(7. 6%) (x2 = 14. 573,8. 019 ,Pa < 0.05) , whereas no significant difference was found between the T2DM group and IGT group (P > 0. 05). The incidences of vascular diffusing pathological change in the IGT group (24. 8%) and T2DM group (30. 8%) were higher compared with the NGT group (12.4%) (x2 =8.583,16.724, Ps < 0.05), whereas there was no significant difference between the IGT group and T2DM group (P >0.05). The Gensini scores in the IGT group (55. 05 ± 22. 99) and T2DM group(56. 15 ± 24. 87) were significnatly higher than that of the NGT group (38. 03 ± 17. 38), the differences were significant ((t =17.0142,18. 1186,Ps <0.01),whereas there was no significant difference between the IGT group and T2DM group (P>0.05). Conclusion The incidences of 2 and 3 vessels pathological changes increase significantly in patients with IGT. Moreover, the incidences of occlusion and diffuse stenosis increase significantly. This is similar to the coronary artery pathological charactersitics in patients with diabetes, which indicates that IGT is closely related to the pathological severity of coronary artery. We should pay much attention to those patients with IGT in the clinical work.
