China Pharmacy 2016;27(3):392-394
OBJECTIVE:To establish the quality standard for Chaige ganmao mixture. METHODS:TLC was conducted to iden-tify the Scutellaria baicalensis and Paeonia lactiflora;HPLC was conducted to determine the content of puerarin. The column was Zorbax Eclipse XDB-C18 with mobile phase of methanol-water(25:75,V/V)at flow rate of 1.0 ml/min,detection wavelength was 250 nm,and column temperature was 25℃,and the injection volume was 5μl. RESULTS:TLC showed clear spots and good sepa-ration. The linear range of puerarin was 18-198 μg/ml(r=0.999 9);RSDs of precision,stability and reproducibility tests were low-er than 2%,recovery was 99.04%-99.75%(RSD=0.28%,n=6). CONCLUSIONS:The standard can be used for the quality con-trol of Chaige ganmao mixture.

Objective To investigate the expression and clinical significance of UL16 binding protein 3 (ULBP3) in human esophageal squamous cell carcinoma (ESCC) and its correlation with nature killer (NK) cells.Methods The relative expression of ULBP3 in the ESCC tissues and corresponding carcinoma adjacent tissues of 40 patients was detected by realtime-poly merase chain reaction (PCR),immunohistochemical staining and Western blot methods.The percentage of NK cells in peripheral blood of same patients was examined by flow cytometry.The correlation between ULBP3 and the percentage of NK cells was analyzed with Pearson method.Results The expression of ULBP3 at mRNA level in the tumor tissues ([4.96 ±-6.11]×10-3) was significantly higher than that of corresponding carcinoma adjacent tissues ([1.64 ± 2.96]× 10-3,t =3.656,P< 0.01).The immunohistochemical staining results indicated that the positive rate of ULBP3 in the tumor tissues was 60% (24/40),however that of corresponding carcinoma adjacent tissues was only 32.5%(13/40,t=3.921,P<0.01).The Western blot results indicated that the expression of ULBP3 at protein level in the tumor tissues was significantly higher than that in the corresponding carcinoma adjacent tissues.The relative expresssion ULBP3 at mRNA level in carcinoma tissues of ESCC patients with lymph node metastasis and at TNM stage Ⅲ was higher than that of ESCC patients without metastasis and at TNM stage Ⅰand Ⅱ (t=4.839,4.192,P<0.05).There was no significant correlation between the expression and ages,gender,location of tumors and the differentiation degree of tumor (P>0.05).At early and mid stage of the tumor,the expression of ULBP3 at mRNA level was positively correlated with the percentage of NK cells in peripheral blood (r=0.5233,P<0.05),however there was no correlation at advanced stage.Conclusion ULBP3 was highly expressed in ESCC and may be involved in the immune regulation of NK cells.

Patients with metastatic prostate cancer are typically managed with androgen deprivation therapy. Most patients initially respond to treatment, but many eventually develop castration-resistant prostate cancer. Neuroendocrine prostate cancer (NEPC) is a highly aggressive subtype of castration-resistant prostate cancer, which often results from neuroendocrine differentiation of prostate cancer cells. NEPC has a dismal outcome with an average survival of less than 1 year and exhibits less response to radiochemotherapy. At least 25%of patients with lethal castration-resistant prostate cancer are predicted to eventually develop this type of highly-aggres-sive NEPC. However, research on the molecular mechanism of NEPC is limited;thus, further studies are needed to explore the develop-ment and application of anticancer drugs for NEPC.

Objective To investigate the clinicopathologic features and imaging findings of several kinds of rare and uncommon brain embryonal tumours. Methods MRI or CT appearance and clinicopathologic features in 10 eases of histopathology confirmed brain embryonal tumours were retrospectively analyzed.Results Among 10 cases,there were supratentorial primitive neuroectodermal tumour(sPNET) in 6,ependymoblastoma in 2,medulloepithelioma and atypical teratoid/rhabdoid tumour (AT/RT)in 1 respectively.Patients in 4 cases were infancy and childhood.There was characteristic of the clinicopathologic features of tumors that were the evidence of accurate diagnosis. All lesions were located in the supratentorial region.The tumors were large,usually lobulated in shape irregularly and showed heterogeneous density or signal intensity with some cystic and necrotic areas.The tumors parenchyma appeared slightly high density on CT imaging,iso-or high signal on T2WI and slight low signal on T1WI with intense enhancement after contrast injection.Conclusion MRI or CT findings of rare and uncommon brain embryonal tumours were not characteristic,it Was very essential to know the tumors combined with the clinical and pathologic features.

ABSTRACT:Objective To evaluate the expressions of cell adhesion molecules CD146 and transferrin receptor 1 (TfR1)in ovarian epithelial cancer and investigate their relationship with clinical pathological features of patients with ovarian epithelial cancer (OEC ) so as to further explore the pathogenesis of OEC. Methods Immunohistochemistry was employed to determine the expressions of CD146 and TfR1 in normal,benign and ovarian cancer tissues.Results The immunohistochemical results showed that the positive expressions of CD146 and TfR1 gradually increased with the changes of normal,benign and malignant tissues in OEC.There were significant differences between all the groups (P<0.05).The advanced the clinical stage,the higher the expression rate (P<0 .0 5 ).The lower the histopathological differentiation,the higher the expression rate (P<0 .0 5 ).The expressions of CD146 and TfR1 were not correlated with age or pathological patterns (P>0.05).There was a significant correlation between expressions of CD146 and TfR1 in OEC (P<0.05,rs=0.532).Combined detection sensitivity and specificity were 82.4% and 75.0%.Conclusion The high expressions of CD146 and TfR1 may play a key role in the occurrance,progression and metastasis of OEC.They may be used as potential markers for diagnosis,postoperative follow-up and targeted therapy.

micmRNA (miRNA) plays an important role in biological processes via regulating gene expression in the level of posttranscription.Increasing number of studies reveal that miR-375 is downregulated in digestive system tumors, and is related to tumorigenesis.Overexpression of miR-375 can inhibit growth and metastasis of tumors through repressing the expression of target genes.
