RESUMEN
Primary enteric adenocarcinoma is a rare variant of primary pulmonary adenocarcinoma. This disease lacks a distinctive manifestation and often requires pathological examination to make a definite diagnosis. A male patient visited the Second Xiangya Hospital, Central South University for consistent cough and sputum production for about 1 year. Anti-infection therapy was given but it showed ineffectiveness. Enteric adenocarcinoma was diagnosed after percutaneous lung biopsy according to pathological findings. Combining this case with relevant literature, we summarized the characteristics to raise physicians' awareness for this rare subtype.

Objective:To investigate the clinical efficacy of salvianolate in the treatment of ischemic stroke(IS) and its effect on the serum levels of uric acid, hypoxia Inducible Factor-1α (HIF-1α), neuroglobin (NGB), hypersensitive C-reaction protein (hs-CRP),regulatory T cell(Treg) and helper T lymphocyte 17 (Th17). Methods:Totally 196 IS patients in our hospital were analyzed and divided into the control group(n=96) and the observation group(n=96). The patients in the control group were treated with the traditional therapy,and the patients in the observation group were treated with salvianolate additionally. The clinical effect and disabili-ty were observed;and the serum levels of uric acid,HIF-1α,NGB,hs-CRP,Treg and Th17 were compared between the groups. Re-sults:Before the treatment,there were no differences in uric acid,HIF-1α,NGB,hs-CRP,Treg and Th17 between the groups(P>0.05). After the 14-day treatment,the effective rate was 69.79% in the observation group,which was higher than that in the control group (P<0.05). NIHSS scores and mRS scores of the two groups were lower than baseline values (55.21%,P<0.05). After 3-month follow-up,NIHSS scores,mRS scores and the disability rate(12.5%) in the observation group were obviously lower than those in the control group(P<0.05). After the 14-day treatment,the serum levels of uric acid,HIF-1α,NGB,and hs-CRP in the obser-vation group were lower than those in the control groups (P<0.05). Besides, the patients in the observation group were with more Treg and fewer Th17 than the control group and baseline value (P<0.05). Conclusion:The application of salvianolate in the treat-ment of ischemic stroke can effectively improve the disability and neurological function defects,which should be recommended for the clinical use as an effective drug.
RESUMEN
Objective To explore the relationship between myc/bcl-2 and myc/p53 co-expression and the prognosis of diffuse large B-cell lymphoma (DLBCL). Methods A total of 148 DLBCL cases with the follow-up data in Shanxi Cancer Hospital from January 2010 to October 2014 were selected. The expression of myc, bcl-2 and p53 protein in paraffin samples was detected by immunohistochemistry (IHC). Results The positive expression rate of myc, bcl-2 and p53 was 35.1 % (52/148), 60.1 % (89/148) and 24.3 % (36/148) respectively in 148 patients with DLBCL. There were 37 (25.0%) cases of myc/bcl-2 co-expression, which were correlated with Hans classification (χ2= 4.749, P= 0.029), IPI score (χ2= 4.894, P= 0.027), bone marrow invasion (χ2= 4.751, P= 0.029), and efficacy evaluation (χ2= 9.14, P= 0.003). Myc/p53 co-expression was detected in 17 cases (11.5 %), which was associated with Hans classification (χ2 = 5.349, P= 0.021) andLDH level (χ2= 11.1, P= 0.001). Univariate analysis revealed that myc [overall survival (OS): χ2= 6.044, P= 0.014; progression free survival (PFS):χ2= 6.212, P= 0.013], bcl-2 (OS:χ2= 5.812, P= 0.016; PFS:χ2= 4.878, P= 0.027), p53 (OS:χ2= 20.092, P< 0.0001; PFS:χ2= 18.492, P< 0.0001), myc/bcl-2 co-expression (OS: χ2= 11.277, P= 0.001; PFS:χ2= 9.024, P= 0.003) and myc/p53 co-expression (OS: χ2=21.150, P< 0.0001; PFS: χ2 = 18.655, P< 0.0001) were the adverse prognostic factors. In addition, the survival rate of the co-expression group was lower than that of single expression group, and the survival rate of myc/p53 co-expression group was lower than that of myc/bcl-2 co-expression group. Multivariate analysis showed that among the six independent variables, including myc, bcl-2, p53, myc/bcl-2, myc/p53 and treatment regimen, p53 expression was an independent prognostic affecting factor of OS (95%CI 0.172ˉ0.763, P=0.008) and PFS (95%CI 0.172ˉ0.773, P=0.009). Conclusion Myc, bcl-2 and p53 are the poor prognostic factors in DLBCL. Myc/bcl-2 and myc/p53 co-expression have synergistic effect, indicating the poor prognosis.

Objective: To compare the clinical characteristics and plasma level of N-terminal pro-brain natriuretic peptide (NT-proBNP) between the patients with hypertensive hypertrophic cardiomyopathy in elder age (HHCME) and the patients with hypertensive left ventricular hypertrophy (HTN-LVH). Methods: Our work included 2 groups, HHCME group,n=47 and HTN-LVH group,n=44. Duplex Doppler echocardiography was performed to determine left atrial diameter (LAd), left ventricular end-diastolic dimension (LVEDd), interventricular septal thickness (IVST), left ventricular ejection fraction (LVEF), velocity of early diastolic period (VE) and velocity of end-diastolic period (VA) in mitral valve oriifce. Plasma level of NT-proBNP was measured by ELISA. The above indexes were compared between 2 groups. Results:①Compared with HTN-LVH group, HHCME group presented decreased LVEDd and increased IVST, LVEF, allP0.05.②Plasma level of NT-proBNP was higher in HHCME group,P Conclusion: The plasma NT-proBNP level was higher in HHCME patients than that in HTN-LVH patients which indicated that HHCME patients may have worse prognosis. NT-proBNP might be helpful for differencing HHCME.
RESUMEN
BACKGROUND: The effect and mechanism of peroxisome proliferator-activated receptor gamma (PPARγ) agonists on transforming growth factor (TGF)-β1-induced fibrotic responses in lung fibroblasts remain unclear, and seldom reported.OBJECTIVE: To study the effects of PPARγ agonists on TGF-β1-induced fibrotic responses in lung fibroblasts, so as to investigate its effects in preventing pulmonary interstitial fibrosis of silicosis. METHODS: The pulmonary alveolar macrophage was prepared with 200 mg/L SiO2 and the supernatants were got. Chinese hamster lung fibroblasts were incubated with the prepared supernatants. Then a cellular model in vitro for studying pulmonary fibrosis induced by SiO2 was developed. Chinese hamster lung fibroblasts were cultured to observe the effects of the PPARγ ligand (15 d-PGJ2) and its agonists (troglitazone and ciglitazone) on the expression of TGF-β1-induced fibronectin. RT-PCR was used to detect the mRNA expression of fibronectin and Western blotting was used to detect the protein expression of fibronectin. RESULTS AND CONCLUSION: (1) The expression of TGF-β1 mRNA showed an effect in a dose- (0-5 μg/L) and time- (0-24 hours) dependent manner. (2) PPARγ ligands and agonists reduced the mRNA and protein expressions of fibronectin. Results suggested that PPARγ agonists can inhibit TGF-β1-induced fibronectin synthesis after stimulation by SiO2 and may play a potential role in preventing pulmonary interstitial fibrosis.
