Objective To improve the understand of the clinical characteristics of mycosis fungoides and provide guidance for the clinical work. Methods The clinical data of 21 patients with mycosis fungoides in our hospital were retrospectively analyzed including the ages at diagnosis, clinicopatholagic characteristics of skin lesions, systemic manifestation, misdiagnosis and treatment of these patients. Results The mean age was (57.3±2.31) years at the diagnosis. Most patients were at the stage of plaques. Clinical manifestations included generalized lesions (52.4 %) and itchy (66.7 %). Epidermotropism (66.7 %) and pautriers microabscesses(57.1%) were common histopathologic features. Previous misdiaguosis rate was 66.7 %. Skin targeted therapies and biologic therapies were effective approaches to relieve the skin rash at early stage, and combined chemotherapy was typically applied in more advanced cases. Conclusion Mycosis fungoides has various clinical characteristics and careful differential diagnosis should be made in clinical practice.

Objective To study the association between functional genetic polymorphisms of IL-1B(T-31C,C-511T),IL-1RN and the susceptibility to gastric cancers. Methods A case-control study was conducted in 180 gastric cancer cases and 308 age-and sex-matched cancer-free controls.Genotypes were detected by PCR-restriction fragment length polymorphism(PCR-RFLP) assays,and association between genotypes,environmental factors and risk of gastric cancers were determined. Results IL-1B T-31C was in strong linkage disequilibrium with IL-1B C-511T(D'=0.862,R2= 0.721,P=0.000).Multivariate logistic regression analysis revealed that the variant genotypes of IL-1B T-31C and C-511T were not significantly associated with risks for gastric cancers(adjusted OR,0.95 and 95% CI,0.62-1.47 for IL-1B T-31C;and adjusted OR,0.85 and 95% CI,0.55-1.31 for IL-1B C-511T).The variant genotypes(1/2,2/2) in IL-1RN were associated with a non-significantly increased risks for gastric cancers(adjusted OR,1.32 and 95% CI,0.71-2.36) in all subjects and with a significantly increased risks for gastric cancers in subjects with H.pylori infection(adjusted OR,2.03 and 95%CI,1.02-4.80).Conclusion The functional genetic polymorphisms of IL-1RN may contribute to the risks of gastric cancers in high-risk population,particularly in those with H.pylori infection.

Objective To analyze the characteristics,electroencephalographic(EEG)features,neuroimaging findings,therapeutic effects and prognoses of 114 cases of idiopathic nocturnal frontal lobe epilepsy (NFLE). Methods The clinical data of 114 patients with idiopathic NHLE admitted in the epilepsy outpatient department from June,1999 to January,2007 were collected and analyzed. Results Idiopathic NFLE was clinically characterized by nocturnal clustered,postural or dystonic seizures and complex motor activities.The interictal routine EEG in 22.9% and dynamic EEG in 28% of the cases in wakefuIness and the interictal dynamic EEG in 38% of tbe cases in sleep showed frontal lobe epileptiform discharge,which was found in the EEG during seizure attacks in66.7% of the cases.Drug therapy was effeclive in 79.8% of the cases.with 29.7% of the cases showing complete seizure control. Conclusions Idiopathic NFLE has distinct clinical features wim relatively low rate of EEG abnormality during seizure attack or the interictal period.Frontal lobe epilepsy is more likely to occur in sleep,and sleep EEG is therefore of much importance in the diagnosis of idiopathic NFLE.

OBJECTIVETo evaluate the impact of insulin resistance (IR) on prognosis in non-diabetic acute coronary syndrome patients.
METHODSIn this prospective study, we enrolled 332 non-diabetic patients suffering from acute coronary syndrome. The patients were divided into three groups by HOMA-IR which calculated by formula: low HOMA-IR group (HOMA-IR < 2), 44 cases; moderate HOMA-IR group (2 ≤ HOMA2-IR < 6), 99 cases; high HOMA-IR group (HOMA ≥ 6) with HOMA index, 179 cases. The in-hospital medical records of patients were compared, and all patients were followed up for one year after discharge.
RESULTSIncidence of hypertension (P = 0.013), dyslipidemia (P < 0.001), faster resting heart rate (P < 0.001) and number of triple vessel coronary artery disease (P = 0.017) in high HOMA-IR group were significantly higher than in low and moderate HOMA-IR group. During follow-up, the major end-point events increased in proportion to IR grade: 64.3% (26/44) in the high HOMA-IR group, 54.7% (52/99) in moderate HOMA-IR group and 41.3% (74/199) in low HOMA-IR group (P = 0.034). Multivariable logistic regression analysis showed that high sensitivity C reactive protein (OR = 1.012, 95%CI:1.002-1.022, P = 0.022), HOMA-IR (OR = 1.250, 95%CI:1.043-1.497, P = 0.015) , triple vessel coronary artery disease (OR = 5.914, 95%CI:2.947-11.868, P < 0.001) , ischemic changes on ECG (OR = 5.495, 95%CI:2.925-10.324, P < 0.001) and low left ventricular ejection fraction (LVEF ≤ 40%) (OR = 13.205, 95%CI:5.000-34.661, P < 0.001) were independent risk factor for major end-point events during follow-up.
CONCLUSIONSIncreased insulin resistance is linked with poor prognosis of non-diabetic patients with acute coronary syndrome.

BACKGROUNDRecent studies indicate that bone marrow-derived cells may significantly contribute to atherosclerosis, post-angioplasty restenosis and transplantation-associated vasculopathy. The responsible bone marrow (BM) cells and mechanisms regulating the mobilization of these cells are currently unclear. The purpose of this study was to investigate the expression of granulocyte colony-stimulating factor (G-CSF) on injured arteries and its effects on mesenchymal stem cells (MSCs) differentiation into vascular smooth muscle cells (VSMCs) in the process of vascular remodeling.
METHODSBalloon-mediated vascular injury was established in female rats (n = 100) which received radioprotective whole female BM cells by tail vein injection and male MSCs through a tibial BM injection after lethal irradiation. The injured and contralateral carotid arteries were harvested at 3, 7, 14 and 28 days after treatment.
RESULTSMorphometric analysis indicated that intima to media area-ratio (I/M ratio) significantly increased at 28 days, 0.899 ± 0.057 (P < 0.01), compared with uninjured arteries. Combining fluorescence in situ hybridization (FISH) and immunohistochemical analysis showed that a significant number of the neointimal cells derived from MSCs, (45.2 ± 8.5)% at 28 days (P = 0.01), compared with (23.5 ± 6.3)% at 14 days. G-CSF was induced in carotid arteries subject to balloon angioplasty (fold mRNA change = 8.67 ± 0.63 at three days, relative G-CSF protein = 0.657 ± 0.011 at three days, P < 0.01, respectively, compared with uninjured arteries). G-CSF was chemotactic for MSCs but did not affect the differentiation of MSCs into smooth-muscle-like cells.
CONCLUSIONIncreased expression of G-CSF by injured arteries plays an essential role in contribution to recruitment and homing of MSCs to the site of the arterial lesion.

Objective:
This study aimed to evaluate the role of preoperative two-dimensional (2D) shear wave elastography (SWE) in assessing the stages of liver fibrosis in patients with suspected biliary atresia (BA) and compared its diagnostic performance with those of serum fibrosis biomarkers.
Materials and Methods:
This study was approved by the ethical committee, and written informed parental consent was obtained. Two hundred and sixteen patients were prospectively enrolled between January 2012 and October 2018. The 2D SWE measurements of 69 patients have been previously reported. 2D SWE measurements, serum fibrosis biomarkers, including fibrotic markers and biochemical test results, and liver histology parameters were obtained. 2D SWE values, serum biomarkers including, aspartate aminotransferase to platelet ratio index (APRi), and other serum fibrotic markers were correlated with the stages of liver fibrosis by METAVIR. Receiver operating characteristic (ROC) curves and area under the ROC (AUROC) curve analyses were used.
Results:
The correlation coefficient of 2D SWE value in correlation with the stages of liver fibrosis was 0.789 (p < 0.001). The cut-off values of 2D SWE were calculated as 9.1 kPa for F1, 11.6 kPa for F2, 13.0 kPa for F3, and 15.7 kPa for F4. The AUROCs of 2D SWE in the determination of the stages of liver fibrosis ranged from 0.869 to 0.941. The sensitivity and negative predictive value of 2D SWE in the diagnosis of ≥ F3 was 93.4% and 96.0%, respectively. The diagnostic performance of 2D SWE was superior to that of APRi and other serum fibrotic markers in predicting severe fibrosis and cirrhosis (all p < 0.005) and other serum biomarkers. Multivariate analysis showed that the 2D SWE value was the only statistically significant parameter for predicting liver fibrosis.
Conclusion
2D SWE is a more effective non-invasive tool for predicting the stage of liver fibrosis in patients with suspected BA, compared with serum fibrosis biomarkers.

BACKGROUNDClinical combination of some traditional Chinese medical herbs, including berberine, with irradiation is demonstrated to improve efficacy of tumor radiotherapy, yet the mechanisms for such effect remain largely unknown. The present study investigated the effect of berberine on apoptosis induced by X-rays irradiation and the relation between this effect and gap junction intercellular communication (GJIC).
METHODSThe role of gap junctions in the modulation of X-rays irradiation-induced apoptosis was explored by manipulation of connexin (Cx) expression, and gap junction function, using oleamide, a GJIC inhibitor, and berberine.
RESULTSIn transfected HeLa cells, Cx32 expression increased apoptosis induced by X-rays irradiation, while inhibition of gap junction by oleamide reduced the irradiation responses, indicating the dependence of X-rays irradiation-induced apoptosis on GJIC. Berberine, at the concentrations without cytotoxicity, enhanced apoptosis induced by irradiation only in the presence of functional gap junctions.
CONCLUSIONSThese results suggest that berberine potentizes cell apoptosis induced by X-rays irradiation, probably through enhancement of gap junction activity.
