Objective To evaluate imaging diagnosis, differential diagnosis, surgery and interventional therapy of hepatic angiomyolipoma associated with tuberous sclerosis.Methods Clinical features, imaging appearances and interventional therapy for 2 cases of HAML in TS were retrospectrively analyzed. Results The features of HAML in TS are as following:(1) Two cases were female with no history of hepatitis and hepatocirrhosis, liver function test and alpha feto protein were normal. (2) the tumor was shown as a multiple hyperechoic mass with sharp margin on ultrasonography; well defined, fat density and intensity mass on computerized tomography (CT); hypervascular mass with early drainage of hepatic vein and tumor staining on angiography. (3) One case underwent interventional therapy. After 42 month follow up, the tumor was found to be diminished in size. Another case was under monitored with only the enucleating of left renal mass. The hepatic tumor showed no change after 10 months.Conclusions The imaging appearances of HAML in TS are relatively characteristic. Superselective arterial embolization is an effective treatment for HAML in TS.

Objective To evaluate the effect of exercise on the relationship between body mass index (BMI) and health-related quality of life (HRQOL).Methods A total of 1 114 participants were recruited from the Physical Examination Center of two hospitals.SF-36 was used to measure HRQOL,and the classification of sports level was done according to the subjective evaluation of participants.Results The total score of HRQOL,physical component summary and mental component summary were 76.26± 16.10,75.97 ± 16.67 and 76.55± 18.33 respectively.The results of correlation analysis were as following:the positive correlation between BMI and general health (r=0.109),vitality (r=0.116),social functioning (r=0.092),role emotional (r=0.122),mental health (r =0.145) were significant (P＜ 0.01).The negative correlation between BMI and PF(r=-0.07,P=0.019)was significant.The mediation effects of exercise in was relationship between BMI and general health,vitality,mental health were significant,and the mediating effect were 5.84％,9.14％ and 6.58％.Conclusion This study demonstrates that mediation effects of the exercise are significant in some dimensions of HRQOL,but the direct influence of BMI on the HRQOL plays a leading role.And BMI is a protective factor under certain conditions.

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

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.

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

Lack of overall evaluation on the occupational ability of students existed in the national rehabilitation therapy education.And the students faced the problems such as difficulty in relating the theory with the practice and poor practical ability during the clinical internships.Objective structured clinical examination (OSCE), an objective evaluation method, which could be used as reference, could be adopted to simulate the clinical scene to test students' clinical skills.

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 analyze the clinical features and risk factors of urinary tract infection in patients with gestational diabetes mellitus ( GDM).Methods A total of 1 068 patients with GDM were enrolled from Nanshan People's Hospital between January and December 2014.The incidence of urinary tract infection, pathogens distribution and drug resistance rate were retrospectively analyzed.Multivariate Logistic regression was performed to analyze the risk factors of urinary tract infection in GDM patients . Results Among 1 068 patients with GDM, 130 (12.17%) were compliacated with urinary tract infection One hundred of forty-two strains of pathogens were detected in the middle urine culture sample from urinary tract infection patients, Escherichia coli (67.61%,96/142) and Klebsiella pneumonia (11.97%,17/142) were the most frequent strains.Escherichia coli has high resistance to semi-synthetic penicillins, quinolones and sulfonamides, and relatively low resistance rate to carbapenems , aminoglycoside antibiotics and nitrofurantoin.Klebsiella pneumoniae was completely resistant to ampicillin , while was completely sensitive to carbapenems, aminoglycoside antibiotics , piperacillin/tazobactam, aztreonam.Logistic regression analysis showed that glycated hemoglobin ＞6.5%(OR＝8.631, 95%CI 2.969-25.090, P＜0.01), fasting blood glucose＞5.3 mmol/L(OR＝3.116, 95%CI 2.040-4.761,P＜0.01), low density lipoprotein ＞2.6 mmol/L (OR＝1.649, 95%CI 1.083-2.511, P＜0.05), triglyceride＞1.7 mmol/L(OR＝2.986, 95%CI 1.256-7.112, P＜0.05), history of urinary tract infection (OR＝5.561,95%CI 1.315-23.519, P＜0.05) and history of maternity(OR＝1.631, 95%CI 1.018-2.614, P＜0.05) were the independent risk factors for urinary tract infection in GDM.Conclusion The incidence of urinary tract infection in patients with GDM is high.The control of blood glucose and blood lipids , enhanced health education for pregnant women with history of urinary tract infection and history of childbirth may reduce the occurrence of urinary tract infection in GDM patients.
