Purpose To investigate the clinicopathologic features of calcifying aponeurotic fibroma (CAF). Methods The clinical and pathologic profiles of 6 cases of CAF were retrospectively analyzed. Results CAF appeared a firm, painless and slowly growing mass with a predilection for the distal portions of the extremities in young children and adolescents. Microscopically, the tumor consis-ted mainly of benign appearing spindle cells, chondroid cells and calcific debris. Immunohistochemically, the tumor cells were positive for vimentin, HHF-35, S-100, Calponin and CD68. Conclusion CAF is a rare, locally aggressive fibroblastic lesion. It can make an accurate diagnosis by integrating the clinical location with histopathological features. Repeated minor trauma to the extremities and some embryologic cell nests maybe its pathogenesis.

OBJECTIVETo investigate the pathogenic and clinical presentation and laboratory tests of bullous rash in hand, foot and mouth disease (HFMD) in Xi'an from January 2013 to December 2014 by retrospective analysis.

METHODA total of 224 specimens were collected from clinically diagnosed HFMD cases who were characterized by widespread mucocutaneous bullous reactions in Xi'an Children's Hospital from January 2013 to December 2014, the identification and subtyping of the isolates were conducted with real-time fluorescent quantitative RT-PCR. A retrospective analysis was performed to analyze the clinical presentation, laboratory tests and late follow-up problems of the HFMD.

RESULTIn the clinically diagnosed HFMD cases who were characterized by widespread mucocutaneous bullous reactions, 207 were caused by coxsackievirus A6 (CA6), accounting for 92. 4% of all cases with bullous, 4 were caused by enterovirus 71 (EV71), accounting for 1.8%, 10 were caused by coxsackievirus A16 (CA16), accounting for 4. 5%; 4 cases were negative for these viruses. In the cases positive for intestinal virus-nucleic acid, 130 were male, 90 were female; male to female ratio was 1. 44: 1, 203 were <5 years old, accounting for 92. 3%. Leukocytosis was found in 75 cases (34. 1%); high-sensitivity C-reactive protein (hsCRP) increased in 200 cases (90. 9%); elevated myocardial enzyme CK-MB was found in 35 cases (15. 9%), alanine aminotransferase increased in 15 cases (6. 8%); 187 cases had fever (85. 0%). None of the cases had serious complications such as encephalitis or myocarditis. In the course of the critical phase bullous rash or large vesicle-like changes, obvious itching, and facial rash appeared. After the fluid in the bullae was absorbed or the bullae ruptured or became ulcerated, scar formation and large areas of exfoliation occurred, with no effusion on the newly formed epithelium in the base, without significant pigmentation on later follow-up. In the late follow up process, 52 cases in CA6-positive patients (25. 1%) developed onychomadesis within 2-4 weeks after onset, 1 to 8 nails, an average of 4. 3 fell off, new nails grew, the nail bed showed no structural abnormalities and hyperplasia after falling off, the surface was smooth, had no hypertrophy, left no sequelae.

CONCLUSIONThe pathogen in HFMD characterized by widespread bullous reactions was mainly the CA6, this kind of HFMD was mainly mild type, with significant itching, later the bullae may have scar formation and skin exfoliation, in some cases onychomadesis may occur.

ObjectiveTo investigate the correlation between serum C-reactive protein(CRP),tumor necrosis factor-alpha(TNF-α) and atherosclerosis in patients with subclinical hypothyroidism.Methods Seventy-five patients with subclinical hypothyroidism were divided into two groups according to the level of TSH:mild group (42 cases) with TSH between 5.5 and 10.0 mU/L and severe group (33 cases) with TSH ＞10.0 mU/L.Thirty healthy physical examinees or volunteers were selected as control group.TG,LDL-C,HDL-C,TSH,FT4,FT3,CRP,TNF-α and carotid intima-media thickness(CIMT) of all cases were detected and measured.ResultsCIMT of mild,severe and control groups were(0.88 ± 0.20),( 1.12 ±0.21 ),(0.62 ±0.21 ) mm,respectively.CIMT of mild and severe groups were both significantly higher than that of control group,CIMT of severe group was significantly higher than that of mild group (P ＜ 0.01 ).There were no significant differences of CRP and TNF- α among three groups (P ＞ 0.05 ).LDL-C of mild and severe groups were significantly higher than that of control group [ (3.22 ± 0.37),(3.49 ± 0.38 ) mmol/L vs.(2.48 ±0.41 )mmol/L,P ＜0.01 ].HDL-C and TG between mild and control groups had no statistical significance (P ＞0.05).Compared with control and mild groups,HDL-C of severe group decreased [(0.92 ±0.10)mmol/L vs.( 1.21 ± 0.14),( 1.17 ± 0.11 ) mmol/L] and TG increased [ ( 1.50 ± 0.49) mmol/L vs.( 1.11 ±0.53),(1.27 ±0.47) mmol/L](P＜ 0.01 or ＜ 0.05).The levels of TG,LDL-C,TSH,CRP and TNF-α had positive correlation with CIMT (r =0.52,0.37,0.48,0.39,0.45;P ＜0.05 or ＜0.01 ).FT4 was negatively correlated with CIMT (r=-0.24,P＜0.05).HDL-C had no relation with CIMT (r =0.06,P ＞0.05).ConclusionsThere are many abnormalities such as metabolism disorder of blood lipid in patients with subclinical hypothyroidism.The risk of atherosclerosis increases in these patients and inflammatory reaction may not be an important factor of subclinical hypothyroidism complicated with atherosclerosis.

Calcitonin gene-related peptide( CGRP) is the strongest vasodilator discovered to date,the synthesis and release of CGRP are regulated by multiple factors.CGRP possesses multiple biological func-tions,such as vasodilator,myocardial strengthener,lung protector,brain protector,immunomodulator.It plays an important role in regulating the function in the body.

Objective To investigate the effects of icariin (ICA) on partial vasoactive substances in monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH) rat model.Methods Sixty male SD rats were randomly divided into five groups:normal control group,model control group,ICA low-,middle-and high-dose (20,40,80 mg · kg-1 · d-1) group,12 rats in each group.Except for normal control group,the rats were injected with MCT (50 mg · kg-1 · d-1) to establish PAH model.After 1 week MCT-injection,ICA was given by intragastric administration for 3 weeks according to different groups.Mean pulmonary artery pressure (mPAP) was recorded through catheter connected with Power Lab system.Except for normal control group,the right ventricular hypertrophy index (RVHI) was calculated using formula:right ventricle weight/the weight of left ventricle with septum× 100％.The morphology of lung artery was assessed by HE staining.Concentration of angiotensin Ⅱ (Ang Ⅱ),endothelin (ET),prostaglandine F2α(PGF2α),thromboxane A2(TXA2) and prostacyclin (PGI2) in serum was measured by ELISA kit assay.The protein levels of angiotensin converting enzyme (ACE),cyclooxygenase-2 (COX-2) and thromboxane A2 synthetase (TXAS) were analyzed by Western blotting,expression of ACE,COX-2 and TXAS mRNA was measured by real time RT-PCR.Results Compared with the normal control group,mPAP [(48.5±5.2) mmHg] and RVHI (33.3±3.8)％in model control group were significantly increased (P ＜ 0.05),the morphology revealed there was obvious artery remodeling at distal artery,the contents of Ang Ⅱ,PGFA2,TXA2 in serum were elevated,and ACE,COX-2 and TXAS gene expression was up-regulated in rats treated with MCT.ICA (40,80 mg · kg-1 · d-1) treatment significantly attenuated mPAP,RVHI and pulmonary artery remodeling (P ＜ 0.05),and decreased the contents of serum Ang Ⅱ,ET,PGF2β,TXA2,and PGI2,and inhibited the gene expression of ACE,COX-2 and TXAS.Conclusion ICA decreases the contents of AngⅡ,ET,PGI2,PGF2α and TXA2 in the serum of MCT-induced PAH rats,which may be one of the mechanisms underlying ICA inhibiting PAH.

Objective To evaluate the long-term outcome of reconstruction for urinary conti-nence function by using implantation of artificial urinary sphincter (AUS). Methods From 2002 to 2005,15 incontinent patients (14 men and 1 woman) with age range of 19-75 years treated with im-plantation of AUS were followed up. In 15 eases, there were 5 cases with traumatic urinary inconti-nence, 1 with neurogenic stress incontinence, 1 with neurogenic urgent incontinence,6 with postpros-tatectomy incontinence and 2 with neurogenie voiding dysfunction. Three eases had taken urethro-stenotomy, 3 had sphineterotomy and 1 had enterocystoplasty and ureterovesieostomy before the im-plantation for AUS. The patients were followed up for 13-55 months with mean of 37 months. The information about the continence status and pads usage, also the complications were collected. Results After implantation, 13 cases(87%)used AUS device normally, 12(92%)beeame dry and 1 (8%) got social continence. Eleven cases (85%) got continence depending on the original implanted AUS and 15% did continence by reoperation. There were 4 cases(27%) with complications including erosion of skin and urethral in 1, graft rejection in 1, urethral atrophy in 1, and voiding dysfunction in 1. Durability of 11 cases with original implanted devices was 13-55 months with mean of 38 months.Conclusion The implantation of AUS is a long-term reliable method in reconstruction for lower uri-nary tract function.

High mobility group protein box 1 (HMGB1) is a highly conserved DNA binding protein, which is found in the nucleus of a variety of cells in the body, regulating the transcription of cell genes.It plays a role of nuclear binding protein in physiological state.Once released into the cell gap, it performances the role of inflammatory mediators.Recent studies showed that pathogenesis of HMGB1 not only involved in sepsis, autoimmune diseases, chronic liver disease, malignant tumor, but also involved in cell injury repair,which plays important role in a variety of diseases, organ damage, repair process.

OBJECTIVETo investigate the impact of dissected lymph node number on the prognosis of patients with advanced cancer of cardia and stomach fundus.

METHODSClinical data of 236 patients with advanced cancer of cardia and stomach fundus undergone D(2) radical resection were reviewed retrospectively. Five-year survival rate and post-operative complication rate were followed up and their relationships with dissected lymph node number were analyzed respectively.

RESULTSThe 5-year survival rate of the entire cohort was 37.5%. Among those patients with the same stage, the more lymph nodes (LNs) resected, the better survival outcomes achieved(Log-rank trend test P=0.0013). A cut point analysis yielded the ability to detect the significant survival differences. The best long-term survival outcomes were observed with LN counts of more than 20 for stage II(P=0.0136), more than 25 for stage III(P<0.0001), more than 30 for stage IV(P=0.0002) or more than 15 for the entire cohort (P=0.0024), with greatest comparative discrepancies. The post-operative complication rate was 15.7% and was not significantly correlated with dissected lymph node number(P=0.101).

CONCLUSIONSThe prognosis of patients with advanced cancer of cardia and stomach fundus is associated with the number of resected LNs when D(2) lymphadenectomy is carried out. Suitable increment of dissected lymph node number would not increase the post-operative complication rate.
