Objective:To evaluate the relationships among contrast-enhanced ultrasound (CEUS) features, molecular type, and biomarker expression of breast cancer.Methods:A retrospectively analysis of breast cancer patients confirmed by pathology were performed using Breast Imaging Report And Data System (BI-RADS) ultrasound category lesions in the Second Affiliated Hospital Zhejiang University School of Medicine from May 2020 to April 2021. All patients underwent conventional ultrasound and CEUS before biopsy and/or surgery. The relationships among BI-RADS category, quantitative and qualitative CEUS features and biomarker expression of breast cancer were evaluated.Results:All 149 patients with 149 breast lesions were included. The numbers of BI-RADS category 4A, 4B, 4C, and 5 were 8, 60, 49, and 32, respectively. Among them, the numbers of Luminal A like, Luminal B like (human epidermal growth factor receptor-2 (HER-2) positive), Luminal B like (HER-2 negative), HER-2 overexpression and triple negative type were 81, 29, 17, 15, and 7. No significant correlations were found among BI-RADS category, molecular types, and biomarker estrogen receptor (ER), progesterone receptor (PR), HER-2, and antigen Ki-67 (Ki-67) expression (all P>0.05). There were no correlations between quantitative or qualitative CEUS features and molecular types of breast cancer (all P>0.05). There were no correlations between qualitative CEUS variables and ER, PR, HER-2, and Ki-67 expression (all P>0.05). Ascending slope (AS) were negatively correlated with ER and PR expression( r=-0.40, P=0.01; r=-0.35, P=0.03). Descending slope (DS) were positively correlated with ER and PR expression( r=0.42, P=0.01; r=0.36, P=0.03). Arrive time (AT) were positively correlated with HER-2 expression( r=0.37, P=0.02). Conclusions:AS and DS are correlated with ER and PR expression.Arrive time (AT) is correlated with HER-2 expression. The quantitative variables of CEUS are helpful for evaluation of biomarker expression in breast cancer.

Objective:To investigate the effect of epidermal growth factor receptor tyrosine kinase inhibitor on the radiosensitivity of human non-small cell lung cancer cells and its possible mechanism.Methods:Human non-small cell lung cancer cells H1299 were cultured in vitro. CCK-8 was used to detect the toxic effects of erlotinib on H1299 cells, IC 50 and IC 20 were calculated, and IC 20 was utilized as the drug concentration for subsequent experiments. The colony formation assay was performed to identifiy the effect of X-ray combined with erlotinib on H1299 cells, the radiosensitivity parameters were calculated, and the cell survival curves were delineated. Flow cytometry was conducted to detect the cell cycle distribution and apoptosis. Western blot analysis was used to detect the expression of EGFR/PI3K/AKT pathway and apoptosis-related proteins. Results:Erlotinib exerted inhibitory effect upon the proliferation of H1299 cells, IC 50 was calculated as 27.3 μmol/L, and 3.3 μmol/L for IC 20. X-ray combined with IC 20 concentration of erlotinib could reduce the cloning ability of H1299, increased the proportion of G 0/G 1 phase and G 2/M phase, decreased the proportion of S phase, aggravated cell apoptosis, down-regulated the expression of pEGFR and pAKT proteins, and up-regulated the expression of apoptosis-related proteins including Active Caspase 3 and Cleaved PARP. Conclusions:Erlotinib exerts a radiosensitizing effect on H1299. The possible mechanism is that erlotinib combined with radiation can suppress the EGFR/PI3K/AKT pathway, reduce the ability of repairing cell damage, change cell growth cycle and induce cell apoptosis.

Objective To study the effect of astragalus polysaccharides combined with hUSCs transplantation on type 2 diabetic rats. Methods Twenty-five SD rats were randomly selected into the normal control group, and the remaining 105 SD rats were used to establish type 2 diabetes model. The 100 rats successfully modeled were randomly divided into the diabetes group, astragalus polysaccharide treatment group, hUSCs treatment group, and astragalus polysaccharide+hUSCs treatment group, with 25 rats in each group. After 2 weeks of treatment, the FBG concentration, insulin and C-peptide concentrations, and body weight changes were measured in each group. The distribution and survival of PKH-26-labeled hUSCs in rat pancreatic tissue were observed by fluorescence microscopy. TUNEL method was used to detect the apoptosis of rat islet cells. Real-time quantitative PCR and Western Blot were used to detect the expression of TGF-β/Smad signaling pathway-related genes in rat pancreatic tissue. Results The FBG concentration of rats in the astragalus polysaccharide treatment group, hUSCs treatment group and astragalus polysaccharide +hUSCs treatment group were significantly decreased, and that in the combination treatment group was significantly lower those in the astragalus polysaccharide group and hUSCs group, and the differences were statistically significant ( all P<0 . 05 ) . Compared with the diabetic group , the insulin concentration, C-peptide concentration and body weight in the astragalus polysaccharide treatment group, hUSCs treatment group and combination treatment group rats were significantly increased, and those in the combination treatment group was significantly higher than those in the astragalus polysaccharide treatment group and in the hUSCs treatment group, the differences were statistically significant( all P<0.05). The results of fluorescence microscopy showed that the number of PKH-26 positive hUSCs in the combined treatment group was 74.64 ±9.75 in each high power field, which was significantly higher than that in the hUSCs treatment group (43.64±5.83), the difference was statistically significant (P<0.05). Compared with the diabetic group, the apoptotic rates of islet cells in the astragalus polysaccharide treatment group and the hUSCs treatment group were reduced, and the relative expressions levels of mRNA and protein of TGF-β1, Smad3, and Smad7 in the pancreatic tissue were also significantly reduced(all P<0.05). The reduction was more significant in the combination treatment group, and the differences were statistically significant (all P<0.05). Conclusions Astragalus polysaccharide combined with hUSCs transplantation can effectively reduce the FBG concentration, increase the concentration of insulin, C-peptide and body weight, reduce the apoptosis of pancreatic islet tissue, which may be related to the reduction of TGF-β/Smad in pancreatic tissue. Signaling pathways are involved in suppressing the inflammatory response.

The chalcone synthase (CHS) superfamily of the type III polyketide synthases (PKSs) generates backbones of a variety of plant secondary metabolites. Benzalacetone synthase (BAS) catalyzes a condensation reaction of decarboxylation between the substrates of 4-coumaric coenzyme A and malonyl coenzyme A to generate benzylidene acetone, whose derivatives are series of compounds with various biological activities. A BAS gene Pcpks2 and a bifunctional CHS/BAS PcPKSI were isolated from medicinal plant P. cuspidatum. Crystallographic and structure-based mutagenesis studies indicate that the functional diversity of the CHS-superfamily enzymes is principally derived from small modifications of the active site architecture. In order to obtain an understanding of the biosynthesis of polyketides in P. cuspidatum, which has been poorly described, as well as of its activation mechanism, PcPKS2 was overexpressed in Escherichia coli as a C-terminally poly-His-tagged fusion protein, purified to homogeneity and crystallized, which is helpful for the clarification of the catalytic mechanism of the enzyme and lays the foundation for its genetic engineering manipulation.

The statistics of purified protein derivative (PPD) test and chest radiograph of freshmen at a university from 2007 to 2010 were collected and examined.The result showed 25 tuberculosis cases (a prevalence rate of 0.18％) and 1 790 cases (13.40％) with strong positive PPD.After giving informed consents,the students with strong positive result and no abnormality on chest radiograph were divided into two groups.The treatment group (n =814) received precautionary anti-tuberculosis treatment while the nontreatment group (n =976) had no treatment.And 34 tuberculosis cases were found during four years in school (0.25％).Except for freshmen in 2008,the prevalence rate of the strong positive PPD groups much higher than that of the positive and negative groups and the difference had statistic significance between the groups (x2 =23.20,10.58,18.80,P ＜ 0.05).Therefore PPD test and chest radiograph are two main methods for an early diagnosis of tuberculosis among freshmen.Adopting precautionary anti-tuberculosis treatment for students with strong positive PPD and regular physical examinations are effective measures for tuberculosis control at universities.
