Objective To evaluate the prognostic factors in locally advanced non-small-cell lung cancer (LA-NSCLC) for selectively carrying out prophylactic cranial irradiation (PCI).Methods 114 patients with LA-NSCLC between Jun 2006 and Oct 2010 were retrospectively analyzed. Related risk factors and features about brain metastases were analyzed.Results The 2-year incidence rate of brain metastases was 31.58 % (36/114),the first brain metastases was 20.18 % (23/114),and sole brain metastases was 9.65 %(11/114),respectively.Variables involved in the equation of binary logistic regression analysis were pathology (OR =5.892) and treatment mode(OR =2.888).The incidence rate of brain metastases in patients of non-squamous carcinoma and single treatment mode was higher than others (P < 0.01) Model fitting is better (P > 0.05).Overall accuracy rate of predicting brain metastases is 67.7 %.The increased rate of lactate dehydrogenase in the patients with brain metastases or death was 17.54 %, which was higher than that in the survival patients without brain metastases (P < 0.01).At the same time,the station number and the number of mediastinal lymph node metastases were positively correlated (r =0.716, P < 0.01).The incidence rate of brain metastases or mortality rate was higher in the adenocarcinoma cases than that in the squamous carcinoma cases (P < 0.01,P < 0.05),with more frequent occurrence of mediastinal metastases.The mean diameter of squamous carcinoma and adenocarcinoma were 5.8 cm and 3.9 cm, respectively (P < 0.01).Conclusions The incidence rate of brain metastases was higher in patients with single treatment.Large primary tumors, high lactate dehydrogenase, non-squamous carcinoma, multiple stations, and multiple mediastinal lymph nodes metastases can be regarded as risk factors of brain metastases to perform PCI.

Objective To evaluate the clinical value of ultrasound breast imaging reporting and data system (BI‐RADS) in small solid breast masses with diameter ≤1 cm. Methods The ultrasound features of 230 solid breast masses with diameter ≤ 1 cm were described by ultrasound BI‐RADS, the relationship between ultrasound features, BI‐RADS final assesment and pathology were analyzed. Results Of these 230 masses, 72 (31 3.% ) were pathologically confirmed to be malignant and 158 (68 7.% ) to be benign. The ultrasound BI‐RADS features of mass shape, margin, orientation, posterior acoustic features, and microcalcificaition were significantly different between malignant and benign masses( P < 0.05). Irregular shape, noncircumscribed, nonparallel orientation, postrior shadowing, microcalcifications were regarded as malignant ultrasound features, their positive predictive values(PPV), sensitivity, specificity and accuracy for malignancy were 53 3.% -100%, 2 8.% -75 0.%, 82 3.% -100%, 69 6.% -80 9.%, respectively. One hundred and fifty‐two(66.1% ), 62(27 0.% ), 16(7 0.% ) masses were classified into grade 3, 4, and 5, respectively. The PPV for grade 3, 4 and 5 were 10 5.%, 64 5.%, 100% respectively. Among BI‐RADS grade 3 cases, 87 5.%malignant masses were intraductal carcinoma in situ and special type of invasive cancer, among pathological benign BI‐RADS grade 4 masses, 90 9.% were hyperplasia and intraductal papilloma. Conclusions In small breast masses with diameter ≤ 1 cm, due to the sensitivity of malignant signs are not high, the overlap between signs of benign and malignant lesions, pathological type and other factors, the positive predictive value of BI‐RADS grade 3 is higher than criteria of American College of Radiology, so BI‐RADS classification requires further detailed study.

The in vitro release behavior, in vivo biodistribution and antitumor activity of N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer-5-fluorouracil conjugates (P-FU) were studied. The in vitro release behavior was evaluated by determining the amount of 5-fluorouracil (5-FU) released from P-FU in mice plasma at 37 degrees C. The in vivo biodistribution and therapeutic evaluation were investigated with Kunming mice bearing hepatoma 22 (H22). The in vitro half-life (t1/2) of P-FU in mice plasma was 32.4 h. It appeared that the circulation life time of the conjugates were 166 times longer than that of 5-FU. The AUC and t1/2 of P-FU in tumor were 3.3 times and 2.3 times more than those of 5-FU, respectively. Therapeutic evaluation also demonstrated that the treatment with P-FU displayed stronger inhibition of the tumor growth when compared with that of 5-FU (P < 0.05). HPMA copolymer is a potential carrier for 5-FU for effective treatment of cancer.

Objective:To evaluate the value of prenatal ultrasound in localization, qualitative diagnosis and prognosis of adrenal mass in fetus.Methods:According to the pathological and follow-up results, the clinical data, ultrasonographic features and prognostic results of 43 cases of fetal adrenal mass in Changsha Maternal and Child Health Hospital were collected and analyzed, and statistical analysis was performed.Results:In this group, 43 cases of adrenal mass lesions were detected by prenatal ultrasound in 172 561 fetuses, with a detection rate of 2.49/10 000 (43/172 561). There were 19 cases of adrenal hematoma (5 cases were not excluded as adrenal neuroblastoma), 10 cases of subphrenic free lung, 8 cases of adrenal cyst, 3 cases of adrenal neuroblastoma, and 3 cases of adrenal teratoma. The coincidence rate of prenatal ultrasound diagnosis was 100%. The gestational weeks of isolated lung were earlier than those of neuroblastoma, hematoma, teratoma and cyst ( P=0.035, 0.031, 0.043, 0.025), but there was no significant difference among other groups ( P>0.05). There was no significant difference in tumor diameter among the groups ( P>0.05). The initial finding of subphrenic free lung was the earliest at the gestational week, 43 fetused were born, 18 cases were treated with surgery, 24 cases were observed, 1 case was abandoned for treatment, follow-up found that the prognosis of the other cases were good except for 1 death. Conclusions:Prenatal ultrasound has a good advantage in prenatal diagnosis and differential diagnosis of adrenal mass lesions. The overall prognosis of fetal adrenal masss is good.

OBJECTIVETo evaluate the effect of PKC-delta inhibitor Rottlerin on human colon cancer cells and its mechanism.
METHODSHuman colon cancer cell line SW1116 cells were treated with Rottlerin. The transcriptional level of DNA methyltransferase (Dnmt)1, Dnmt3a and Dnmt3b was detected by real-time RT-PCR. Cell cycle distribution was evaluated by flow cytometry (FCM). In addition, cellular morphological changes were examined by light microscopy.
RESULTSPKC-delta inhibitor decreased the expression of Dnmt1, Dnmt3a mRNA, up-regulated APC, p21(WAF1) and p16(INK4A) mRNA. Demonstarted by flow cytometry, Rottlerin increased the percentage of cell cycle G0/G1 phase cell numbers (P = 0.02) and decreased the percentage of cell cycle G2/M phase cell numbers (P = 0.01). Remarkable changes of cellular morphology were observed under light microscope: The volume and cytoplasm of cells treated with Rottlerin were increased. The cell contour was not very clear, and mitotic figures were less frequently seen.
CONCLUSIONPKC-delta inhibitor Rottlerin inhibites cell division and proliferation of the colon cancer SW1116 cells through regulating DNA methylation and blocking the signaling pathway of mitogen-activated protein kinase (MAPK).
