Objective To explore the imaging features of liver tumors with real-time tissue elastography.Methods Eighty-five liver lesions in 67 cases were scanned with conventional ultrasonography and elastography using HI-Vision900 system and then assessed with grade scores.Results on ultrasound were compared with those on pathology.Results Majority of lesions with grade a-b on elastography were identified as benign on pathology, while most of masses with grade c-e on elastography were confirmed as malignant on pathology.The sensitivity, specificity and accuracy were 93.5%, 87.0% and 91.8% for elastography to detect malignant lesions,74.2% ,73.4% and 74.1% for conventional ultrasound.The Kappa value of two doctors on elastography in group Ⅰ (the depth of the lesion ≤10cm) was significantly higher than group Ⅱ (the depth of the lesion ＞10cm).Conclusions Real-time tissue elastography of liver tumors provides a new convenient,non-invasive diagnostic methods,contribute to identify the benign and malignant live tumors.

Objective To study the clinical presentations,radiologic features,prognosis,and possible causes of liver injury associated umbilical venous catheter (UVC ).Methods We reviewed database of our NICU from December 2012 to November 2015 and identified preterm infants with liver injury while UVC in place.The gestational age,birth weight,gender,days of UVC in place prior to liver injury, the depth of UVC (cm),UVC tip position,ultrasound findings of liver injury,laboratory tests,treatment and outcomes were collected.Results During study period,322 infants received UVC insertion.Ten cases (3.1 %)of liver injury associated with UVC were diagnosed.Of the ten infants,nine were diagnosed as extravasation of fluid to liver parenchyma,and one was diagnosed as liver hematoma.The mean birth weight was (1184 ±207)g,mean gestational age was (28.5 ±1.7)weeks.The UVC tip was at thoracic (T) vertebrae T 9 to T 11 level,nine UVC tips were below the right diaphragm level.All UVCs were used for total parenteral nutrition before liver injury was diagnosed.Six infants had clinical manifestations,and four infants were free of clinical manifestations.The most prominent clinical signs were abdominal distension (n =5),weak bowel sounds (n =5)and hepatomegaly (n =4).One infant who was diagnosed with liver hematoma also had progressive hemoglobin decline (minimum 34 g/L)and shock.Abdominal ultrasound showed well-limited,irregular,hyperechoic rimmed lesions with heterogeneously hypoechoic centers or anechoic liquid dark space.Extravasation of fluid to liver parenchyma will restorate within one week after the UVC was remove.One baby who was diagnosed as liver hematoma passed away at 9 days of life.Liver ultrasound of eight returned to normal in 52 days to 3.5 months,and one had calcified lesions at 9 months of age.Conclusions Liver injury is an unusual complication of UVC insertion and usage.Proper positioning of the UVC tip may help to avoid this complication.Early recognition,prompt diagnosis with liver ultrasound examination and timely treatment can lead to better outcome in newborns with extravasation of fluid to liver parenchyma.

OBJECTIVE To observe the effects of RNA interference mediated PIK3CA gene silencing on the proliferation and invasiveness of laryngeal squamous cell carcinoma(LSCC) cells, and investigate the feasibility of PIK3CA gene as a potential therapeutic target in the treatment of LSCC. METHODS The lentiviral vector system expressing short hairpin RNA targeting PIK3CA gene(PIK3C-shRNA)was constructed and transfected subsequently into Hep-2 cells mediated by liposome in vitro. The expression of PIK3CA gene was detected by real-time RT-PCR and Western blot respectively. The proliferation of Hep-2 cells was measured by MTT, colony formation, and cell growth curve. The invasive power was determined by Boyden chamber model in vitro. RESULTS The lentiviral vector system expressing short hairpin PIK3CA- shRNA was constructed successfully. Compared with the control groups, the mRNA and protein expression of PIK3CA were significantly down-regulated(75% and 70% respectively)in the experimental group (P

In this study, based on the transcriptome data, we cloned the full-length cDNAs of TwAACT gene from Tripterygium wilfordii suspension cells, and then analyzed the bioinformation of the sequence, detected the genetic differential expression after being induced by methyl jasmonate (MeJA) by RT-PCR. The full-length cDNA of the TwAACT was 1 704 bp containing a 1 218 bp open reading frame (ORF) encoding a polypeptide of 405 amino acids (GeneBank accession No. KP297934). The deduced isoelectric point (pI) was 6.10, a calculated molecular weight was about 41.20 kDa, and online prediction showed that TwAACT had two catalytic active sites. After the induction of MeJA, the relative expression level of TwAACT increased rapidly. The expression level of TwAACT was highest at 24 h. TwAACT was cloned firstly, that laid the foundation for identifying thegene and illustrating thebiosynthesis mechanism and its synthetic biology.
