BACKGROUND: LINC01234, a long noncoding RNA (lncRNA), is overexpressed in several cancers, including colorectal cancer (CRC). We investigated the role of LINC01234 in CRC development and confirmed its correlation with Krüppel-like factor 6 (KLF6), a tumor suppressor gene that is dysregulated in CRC. METHODS: We tested mRNA levels using quantitative reverse transcription PCR (qRT-PCR). Tissue samples from patients with CRC, inflammatory bowel disease (IBD), hyperplastic polyp, and adenoma were included. Correlations between clinicopathological parameters, overall survival (OS) rate, and LINC01234 were analyzed using Kruskal-Wallis H test. Additionally, cell proliferation, apoptosis, and tumor formation in nude mice were tested to investigate the mechanism of LINC01234. Western blotting was used to determine protein levels. RESULTS: LINC01234 expression was significantly upregulated in CRC tissues and CRC cell lines than in non-tumor tissues and normal epithelial cells, respectively. LINC01234 was associated with high tumor stage, larger tumor size, and metastasis. Patients with higher LINC01234 expression showed reduced OS. Cell proliferation was inhibited by LINC01234 knockdown, whereas apoptosis was enhanced. Mice injected with SW480 cells with LINC01234 knockdown displayed decreased tumor volume, weight, and Ki-67 levels compared with those injected with control cells. KLF6 was negatively regulated by LINC01234. Overexpression of KLF6 showed effects similar to those observed following LINC01234 knockdown on cell proliferation and apoptosis. CONCLUSIONS LINC01234 could be a prognostic biomarker in CRC patients. Upregulation of LINC01234 in CRC promotes tumor development through negative regulation of KLF6.

Objective To analyze the exposed dose of hippocampus(HC)of T3,T4nasopharyngeal carcinoma patients treated with intensity modulated radiotherapy(IMRT). Methods The bilateral HCs were delineated and were divided into head(HH),body(HB)and tail(HT)for 62 nasopharyngeal carcinoma patients treated with IMRT.The dose parameters of HC were then analyzed. Results The mean dose of left and right HC was(1 127±704)cGy,(1 173±762)cGy. The mean dose of left HH,HB and HT was(1 732±1029)cGy,(820±632)cGy,(423±366)cGy(P=0.000);while the mean dose of right HH, HB and HT was(1 985±1101)cGy,(837±531)cGy,(432±343)cGy(P=0.000).The exposed dose and the volume exposed in different dose of HH were obviously higher than those of HB and HT.The dose parameters of HH,HB and HT decreased in turn. The involvement of sphenoid sinus,ethmoid sinus and cavernous sinus correlated with high exposed dose of HC. Conclusions The exposed dose of HH,HB and HT was different in nasopharyngeal carcinoma patients treated with IMRT.The exposed dose of HH was the highest,which should be emphasized especially. The involvement of sphenoid sinus,ethmoid sinus and cavernous sinus suggest high exposed dose of HC.

Objective To explore the viscoelasticity of relaxed myocardium in vivo through indentation method with an intervention ultrasound indentation system (IUIS). Methods Old myocardial infarction (OMI) models of canine were established by ligating left anterior descending branch of coronary artery for 3 months. The indentation creep tests were used respectively in OMI group and shame group (n=8, each) by IUIS in middle and advanced diastole stage in vivo. Test data were processed with three-parameter solid viscoelasticity model, and the viscoelastic parameters, such as instantaneous elastic modulus (E1), relaxation modulus (E∞), creep elastic modulus (E2) and viscous damping coefficient (η) in normal and infarcted myocardium were obtained and compared. Results All the parameters of E1, E∞, E2 and η increased obviously in OMI group than in sham group shown as follows: 27.81±6.74kPa vs. 6.78±2.43kPa; 17.87±3.59kPa vs. 4.52±1.56kPa; 49.54±14.35kPa vs. 16.82±12.37kPa and 1.97±0.78Pa.s vs. 0.66±0.40Pa.s. The differences were statistically significant (P<0.05). Conclusions IUIS is a feasible method to assess the viscoelasticity of relaxed myocardium in vivo. Three-parameter viscoelasticity model can be used to describe creep properties of relaxed myocardium. Both elastic modulus and viscosity resistance have increased in infarcted myocardium.

Objective To measure volume of breast cancer , calculate tumor volume doubling time (TVDT), and analyze the correlated factors affecting TVDT using three-dimensional ultrasound (3D-US). Methods We applied 3D-US to measure the volume of breast cancer of BI-RADS-US 4A classified by conventional ultrasound. The breast cancer case scanned by 3D-US at least twice (the interval is 3 months at least) without any medical intervention were included in the study. We calculated TVDT according to the formula, and analyzed the affecting factors of TVDT using multiple linear regression. Results Sixty-nine cases were enrolled in the study. The TVDT of breast cancer were from 66 to 521 days , in an average of 185 ± 126 days and the median time of 164 days. We found that: ① there were no statistics significances in TVDT between different breast cancer pattern , smoothing border lines , speculated sign , hyperechoic halo , microcalcification and different rear echo (P > 0.05). ② TVDT of different age groups, lymph node metastasis, pathological grade and NPI score were significantly different (P < 0.05), while menstrual cycle, family history of breast cancer and molecular typing showed no difference (P > 0.05). ③ TVDT of patients with different expression of ER, PR and Ki-67, molecular typing showed statistically difference (P < 0.05), but there was no significant difference between different level of HER2 (P >0.05). ④ multi-factor analysis showed that the NPI score, lymph node metastasis, Ki-67 and molecular typing of breast cancer were relative factors in TVDT (P < 0.05). Conclusions The NPI score , lymph node metastasis , Ki-67 and molecular typing significantly correlate with TVDT of breast cancer. Triple-negative breast cancer in molecular typing has the fastest growth rate.

Objective To compare the clinical and ultrasound features of Klebsiella pneumoniae liver abscess(KPLA) in dia‐betes mellitus(DM ) patients with different levels of HbA1c .Methods Totally 146 patients with diabetes mellitus of Klebsiella pneumoniae liver abscesses(KPLA‐DM )were divided into three groups on the basis of their levels of HbA1c:complete glycemic controlled (HbA1c≤7% );good glycemic controlled (7% < HbA1c≤9% );bad glycemic controlled (HbA1c>9% ) .The patients′characteristics ,clinical features ,ultrasound features and complications among the three groups were compared .Results Compared with patients in complete glycemic controlled group and good glycemic controlled group ,patients in bad glycemic controlled group had lower onset age and longer length of hospital stay(P<0 .05) ,are more susceptible to underlying diseases such as hyperlipoi‐demia and chronic renal failure(P<0 .05) ,had more life‐threatening clinical crisis ,and had higher infection rate(P<0 .05) .KPLA‐DM could be characterized by patchy ,mass like enhancement echoultrasound image .Patients in bad glycemic controlled group al‐so had higher risk of biliary pneumatosis ,hepatic venous thrombosis and gas‐forming pyogenic liver abscess than other two groups (P<0 .05) .Conclusion The ultrasound image of KPLA has characteristics .The occurrence of hepatic venous thrombosis and gas‐forming observed by ultrasound is associated with bad glucose control in KPLA‐DM patients ,which suggests that there may be oth‐er complications such as metastatic infection .
