Objective To investigate the expression of p38 mitogen actirated protein kinase (p38MAPK) in renal fibrosis in diabetic mice. Methods Male homozygous C57 BL/6 mice were divided at random into control group intraperitoneally(i. p.) injected with citrate buffer and diabetes group received 5 consecutive daily intraperitoneal inserum glucose level exceeding 16.7 mmol/L. Mice were killed at 0,4weeks ,8weeks, 12weeks and 16weeks respectively after STZ injected. The kidney tissues were obtained from diabetic and control mice. Serum glucose, extracellular matrix,and 24 h urinary albumin excretion rate(UAE)and the serum creatinine(Scr) were measured. The kidney tissue was used for histological and morphometric studies of glomerular matrix expansion (PAS), and the expression of phosphorylated p38MAPK and TGFβ1 were measured by immunohisteehemical staining. p38MAPK and TGFβ1mRNA were analyzed by reverse transeriptase-PCR. Results The serum level of glucose in diabetic mice increased significantly. Scr and 24 h UAE, and glomerular matrix expansion in diabetic mice were obviously higher than that in control mice. Phosphorylated p38MAPK and TGFβ1 levels were obviously increased in the kidney of diabetic mice compared with those in control mice(P ＜0. 01) ;TGFβ1 expression was positively related to the expression of phosphorylated p38MAPK. Conclusion The overexpression of phosphorylated p38MAPK in kidney shoud play an important role in the development of renal fibrosis associated with diabetic nephropathy in mice.

Objective To assess the clinical diagnostic value of CT guided transthoracic core needle biopsy (TNB) in patients with pulmonary peripheral lesions. Methods The pathological findings, follow up results, mass size, complications due to paracentesis, and other examination results in 223 patients with pulmonary peripheral lesions undergoing TNB were analyzed retrospectively. Results The positive predictive value of malignant lesions was 100%. False negative was found in 3 cases. There was no false positive of malignant lesions in all the cases. The sensitivity and specificity were 93.6% and 100%, respectively. The negative predictive value of benign lesions was 94.8%. There was no significant difference in the satisfaction rate of multiple biopsy between the large and small nodules. The satisfaction rate of a single biopsy of the large nodule was significantly better than that of the small nodule ( P

ObjectiveTo study the clinical features and pathogenesis of ophthalmoplegia in senile patients with diabetes, and access the possibility of its development.MethodsBesides routine ophthalmologic and ocular muscle examination, general and laboratory examinations were also done. Some patients were diagnosed also with the help of image processing.ResultsMonocular involvement happened in all 21 patients. 12 patients suffered from oculomotor nerve paralysis, 5 abducent nerve paralysis, 3 trochlearis nerve paralysis, and 1 compound nerve paralysis. Among these patients with complete oculomotor nerve panalysis, no papillary change appeared.Conclusions Microvascular pathologic change may be the pathogenetic basis of ophthalmoplegia for senile diabetic patients. Its prognosis is favorable if reasonable treatment is made.

AIM:To investigate the expression and probable role of extracellular signal-regulated protein kinase(ERK1/2)in renal fibrosis associated with diabetic in mice.METHODS:Male homozygous C57BL/6 mice were divided at random into control group(intraperitoneally injected with citrate buffer)and diabetes group(received 5 consecutive daily intraperitoneal injections of streptozotocin at dose of 50 mg?kg-1?d-1).All mice were followed up for 16 weeks.Diabetes was confirmed by serum glucose levels exceeding 16.7 mmol/L.Mice were killed at 0,4,8,12 and 16 weeks respectively after streptozotocin injection.The kidney tissues were obtained from diabetic and control mice.Serum glucose,kidney weight/body weight(KW/BW),24 h albumin excretion rate(UAE)and the serum creatinine(Scr)were measured.The kidney tissue was used for histological and morphometric studies of glomerular size,glomerular matrix expansion(PAS),and the expression of TGF-?1,phosphorylated ERK1/2 and collagen Ⅲ by immunohistochemical staining.RESULTS:The serum level of glucose in streptozotocin-induced diabetic mice increased significantly.The kidney weight/body weight ratio,glomerular volume and glomerular matrix expansion in diabetic mice were obviously higher than those in control mice.Serum creatinine and 24 h albumin excretion rate in diabetic mice increased significantly compared with control mice.TGF-?1,phosphorylated ERK1/2 and collagen Ⅲ levels were obviously increased in the kidney of diabetic mice compared with those in control mice(P

Objective To investigate the influence of diversification continuing care on quality of life and activities of daily living of epilepsy patients secondary to cerebral hemispheric atrophy.Methods Twenty epilepsy patients with cerebral hemispheric atrophy,admitted to Second Department of Neurosurgery of Hebei Provincial People's Hospital from March 2012 to December 2014 were selected by convenience sampling method,and divided into the intervention group (12 cases) and control group (8 cases),Patients in the control group were given routine guidance discharge,and intervention group were given continuing nursing intervention.The influence of diversification continuing care on quality of life and activities of daily living of epilepsy patients were compared between two groups.Results Twelve months after discharge,QOL in the control group and the intervention group scored 58.8±20.9 and 77.2±14.3,t=2.37,P ＜ 0.05.The ADL scored 49.42±8.14 and 62.72±7.06,t=2.39,P ＜0.05.Conclusions Diversification continuing nursing intervention is helpful to improve quality of life and activities of daily living of epilepsy patients secondary to cerebral hemispheric atrophy.

Objective To study the application of transcatheter superselective arterial embolization for the spinal tumorectomy preopera-tive.Methods From January 2009 to September 2015,the data of 65 patients with spinal tumor were collected.Before operation,all the pa-tients had been performed the transcatheter superselective arterial embolization by Seldinger technology,the embolization effect and the blood loss volume were recorded.Results The pathological vertebral body of 62 patients were significantly dyed and the tumor-feeding artery were obvious.But no obvious tumor-feeding artery and the tumor dyeing was found in 3 cases.The tumor-feeding artery positive incidence of angi-ography was 95.3%(62/65).All cases intubation was successful but one.After embolization, the pathological vertebral body was removed completely.The blood loss volume was 500-3 000 mL,with an average (1 400.65 ±230.62) mL.Conclusion The transcatheter superse-lective arterial embolization could reduce the blood loss in spinal tumorectomy and the operation risks,and increase the possibilities of radical resection,which is an effective preoperative intervention.

Objective To investigate the micminnammatory state and its relationship with atherosclerosis and cardiac function in patients on continuous ambulatory peritoneal dialysis(CAPD). Methods Sixty-seven CAPD patients,27 non-dialytic stage 5 chronic kidney disease(CKD 5)patients and 27 gender and age matched healthy controls wore enrolled in this cross-sectional study.Clinical data and biochemical parameters were collected.Serum interleukin-6(IL-6)and IL-10 levels were measured by enzyme-linked immunosorbent assay(ELISA).High-sensitivity C-reactive protein(hs-CRP)was measured by immunoturbidimetry.Prevalence of atherosclerosis was detected by carotid uhrasonography while cardiac function was detected by echocardiography. Results Serum levels of inflammatory biomarkers were elevated significantly in CAPI)and CKD 5 patients as compared with healthy controls[IL-6(ng/L):2.400,1.515 vs 0.698;IL-10(ng/L):1.988,1.958 vs 0.277;hs-CRP(mg/L):1.090,1.345 vs 0].Left ventricular mass index(LVMI),myocardial performance index(Tei index 0.75±0.31,0.66±O.27 vs 0.52±0.23)in CAPD and CKD 5 patients increased significantly.The prevalence of carotid artery atherosclerosis and left ventricular hypertrophy(LVH)in CAPD and CKD 5 patients was significantly higher than that in healthy controls.No significant difference of the ultrasonic parameters was found between CAPD and CKD 5 patients.In CAPD patients,IL-6 was positively correlated with Tei index,whereas IL-10 was negatively correlated with INMI and was positively correlaled with ejection fraction(EF).In a multiple regression model,IL-6,self-rating depressive scale(SDS)score and pulse pressure were independent predictors of carotid artery atherosclerosis.Similarly,IL-6 and primary hypertension were independent correlates of Tei index in CAPD patients. Conclusions Microinflammatory state exists in either non-dialytic CKD 5 patients or CAPD patients and it is associated with atherosclerosis and cardiac distunetion.IL-6 is an independent risk factor of atherosclerosis and increased Tei index in CAPD patients.
