Molecular markers have been widely used in the treatment of breast cancer. Cell proliferation markers Ki-67 antigen representing breast neoplasms proliferative activity is associated with clinic pathological features and prognosis and has an important predictive value in assessing the effect of neoadjuvant chemotherapy and endocrine therapy. High expression of Ki-67 is a bad prognostic factor of breast cancer, which is highly related to tumor progression, metastasis and prognosis.

Objective To investigate the effect of different irradiation doses of ultraviolet C ray(UVC)on the expression of basic fibroblast growth factor(bFGF)in granulation tissue of gunshot wound in rabbit limbs.Methods After giving 30mJ/cm2 or 60mJ/cm2 UVC to the gunshot wound of soft tissue of limbs,the expression of bFGF was observed both at the mRNA level and the protein level by the methods of in situ hybridization and immunohistochemistry,respectively.Results On the 7th day after UVC irradiation,the expression of bFGF in UVC-treated groups was significantly higher than that in control group(P

OBJECTIVE:To establish the method for simultaneous determination of 9 common inorganic anions in Huanglian shangqing tablet. METHODS:The accelerated solvent extraction-ion chromatography was adopted. Inorganic anions were deter-mined by Ion Pac AS11-HC anion exchange column,protected by Ion Pac AG11-HC column and eluted by hydroxide potassium so-lution(gradient elution)at the flow rate of 1.2 mL/min. The column temperature was set at 30 ℃,elution time was 18 min,and sample volume was 25 mL. RESULTS:The linear ranges of fluorinion,formate ion,nitrite ion,bromide ion,nitrate ion,sulfate ion,oxalate ion and phosphate ion were 0.1-5 mg/L(r=0.9990-0.9999). The limits of quantitation were 0.020,0.078,0.030, 0.058,0.052,0.068,0.084,0.064,0.074 mg/L,and the limits of detection were 0.005,0.024,0.008,0.017,0.015,0.022, 0.026,0.020,0.021 mg/L,respectively. RSDs of precision,stability and repeatability were all lower than 4.0%;recoveries were 80.00%-125.08%(RSD ranged 0.97%-2.47%). CONCLUSIONS:The method is simple,precise,stable and repeatable,and can be used for 9 common inorganic anions in Huanglian shangqing tablet.

Objective To investigate the significance of measuring carotid arterial intima-media thickness(IMT) and diabetic retinopathy(DR).Methods 76 diabetic patients were divided into three groups:no diabetic retinopathy(NDR),nonpmliferative diabetic retinopathy(NPDR),and proliferative diabetic retinopathy(PDR).20 helath people were chosen as control All subjects were examined by ColorDoppler imaging on the carotid arterial intima-media thickness.Results The mean IMT was significantly higher in T_2DM patients than in normal control group(P

Objective To analyze the clinicaopathological features and treatment of bilateral asynchronous breast cancer.Methods The clinical and pathological data of 13 patients with bilateral asynchronous breast cancer admitted in our hospital from 2010 to 2016 ere retrospectively reviewed.Results The bilateral asynchronous breast cancer accounted for 1.7% of all breast cancer patients admitted n the same period (13/782).The median age of patients at first onset was 47.The modified radical operation was the main surgical lity (12/13 for the first cancer;8/13 for the second cancer).The clinical stage Ⅱ was predominant in all patients (10/13 of the first r;9/13 of the second cancer).Invasive ductal cancer was the most common pathologic type (in 11/13 of the first cancer;11/13 of the cond cancer).Hormone receptors were highly expressed in most of the cases (9/13 of the first cancer;7/13 of the second cancer).The disease-free interval was more than 10 years in most cases (8/13).Among 13 cases local recurrence was detected in 1 case, distant metastases in 2 cases, and 1 case died from distant metastasis.Conclusion The bilateral asynchronous breast cancer has a low incidence;however, a close follow up is necessary for early detection and treatment of the second carcinoma.

To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.

Objective To evaluate DSA and MRI in diagnosing focal nodular hyperplasia(FNH) of the liver.Methods DSA and MRI findings in seven patients with pathologically-proved FNH were retrospectively analyzed.Selective hepatic arteriography with DSA,and both plain and dynamic contrastenhanced MR scans were performed in all patients.The imaging findings were retrospectively evaluated and analyzed.Results On DSA examination,all FNH lesions were hyper-vascular,which were characterized by thickened and tortuous feeding arteries.And the feeding arteries,after entering the lesions,branched off peripherally in a radiation pattern and the lesions were evenly dyed with sharp borders.In venous phase,hepatic vein drainage was demonstrated in 6 cases.On dynamic contrast-enhanced MRI,marked enhancement of the lesions was observed,which lasted until to delayed phase when the lesions still showed hyper-intensity or iso-intensity signals.Scar signal in the lesion's center was seen in three cases,which started to enhance at portal vein phase and maintained to delayed phase.Conclusion On DSA imaging,FNH lesions are characterized by thickened and tortuous feeding arteries that branch off peripherally in a radiation pattern after entering the lesions.And the hepatic vein drainage is also a common finding in venous phase.Dynamic contrast-enhanced MRI can well display the abnormal signal of the central scar of FNH.The combination use of DSA and MRI can effectively improve the diagnostic accuracy for FNH.

OBJECTIVE:To investigate the study of traditional Chinese medicine (TCM) in the treatment of chloasma,and to provide reference for clinical treatment and study of chloasma. METHODS:Retrieved from CBM,Wanfang database,CNKI and VIP,usingchloasmaas subject,the literatures of TCM therapy were collected during Jan. 2003-Dec. 2012. Bibliometric meth-od was adopted to analyze included literatures statistically in respects of publication amount,periodicals,research institution,litera-ture types,citing references,other periodicals citatien times,fund support,distribution of provinces and cities. RESULTS:During 2005-2012,the amount of the literatures increased slowly. Among top 10 journals in the list of publication amount,only Chinese Journal of Aesthetic Medicine was not TCM journal and took up the first place. Among top 7 research institutions in the list of publi-cation amount,TCM colleges took up predominant place,followed by TCM hospitals. The types of the literatures were mainly case report,contrastive study before and after treatment,group-divided control study;the amount of group-divided control studies increased gradually year by year. The references cited were mainly English literatures. There were 82 literatures which were cited by other periodicals more than 10 times;the highest time of other periodical citation per literature was 47 times;only 11 literatures were supported by fund. The institutions of literatures authors were distributed in 32 provinces,cities and autonomous regions of China,mainly in the eastern coastal areas. CONCLUSIONS:More and more attention has being paid to TCM therapy for chloas-ma,but the scope and depth of the studies were inadequate. From the point of view of modern medicine,we can explore the patho-logical TCM mechanism and the treatment method of shortening the course of disease.
