Objective To investigate the characteristic sonographic and pathological features of breast ductal carcinoma in situ (DCIS) without microcalcifications on mammography (MG).Methods Forty cases of DCIS without microcalcifications on MG were retrospectively reviewed.The 40 lesions were classified into mass and non-mass groups according to their sonographic findings.The pathological subtypes and nuclear grades of these cases were also analyzed.Fisher exact test was used to compare the differences of the sonographic accuracy rate,sonographic microcalcification rate,pathological nuclear grade and subtype rate between mass and non-mass groups.Results No abnormal finding was found in sixteen cases (40.0%)on MG and only one case (2.5%) on ultrasonography (US),respectively.The most common sonographic feature of DCIS without microcalcifications on MG were masses (75.0%,30/40),and other sonographic findings were round/oval and irregular shape,microlobulated margin,heterogeneous hypoechogenicity and isoechogenicity,and posterior acoustic feature.Ductal dilatations and heterogeneous isoechogenicity were present in most non-mass lesions of DCIS without microcalcifications on MG (22.5%,9/40).The ultrasonographic microcalcifications were found in 5 cases of DCIS without microcalcifications on MG.The common pathological features of DCIS without microcalcifications on MG were medium-low nuclear grade (85.0%,34/40) and noncomedo (87.5%,35/40).The difference of US accuracy rate in mass and non-mass groups was statistically significant [73.3% (22/30) vs 33.3% (3/9),P=0.047].The differences of US microcalcification rate,pathological subtype and nuclear grade were not significant (P=1.000,0.070).Conclusions The mass appearance and medium-low nuclear grade were most common sonographic findings and pathological features of DCIS without microcalcifications on MG.Ultrasonography should be an helpful tool for improving the diagnostic sensitivity ofmammography in breast DCIS.

Objective To explore the clinical application value of percutaneous kyphoplasty ( PKP ) under the guidance of G arm X ray machine in the treatment of osteoporotic vertebral compression fracture (OVCF). Methods The medical records of eighty-two patients (94 vertebral bodies) with OVCF treated with PKP were collected retrospectively. Thirty-nine cases ( 44 vertebral bodies ) were guided by G-arm X-ray machine to implement PKP,which were recorded as G-arm group. Forty-three cases (50 vertebral bodies) were guided by C-arm X-ray machine to carry out PKP,which were recorded as C-arm group. The operation time, intraoperative fluoroscopy times, bone cement leakage cases, preoperative and postoperative anterior height of injured vertebrae,Cobb angle of injured vertebrae,visual analogue scale scores and Oswestry disability index of the two groups were recorded. Results There was significant difference in operation time and intraoperative fluoroscopy times between the G-arm group and C-arm group (the operation time:(31. 6±5. 2) vs. (45. 8±6. 7) min,the intraoperative fluoroscopy times: (9. 5±2. 3) times vs. (18. 7±3. 5) times,t=-10. 64,-13. 91,P<0. 05) ,while there was no significant difference in the number of bone cement leakage ( P>0. 05) . Compared postoperative and preoperative anterior height of injured vertebrae, Cobb angle of injured vertebrae, visual analogue scale scores and Oswestry disability index scores of G-arm group and C-arm group respectively, the differences were significant ( t=-3. 41 vs. -3. 28, 6. 67 vs. 7. 66, 26. 63 vs. 25. 75 and 10. 41 vs. 11. 90, P<0. 05). There was no significant difference between the two groups (P>0. 05). Conclusion The treatment of OVCF with PKP guided by G-arm X-ray machine could significantly shorten operation time, reduce the intraoperative fluoroscopy times and the operative difficulty,and increase operation safety than PKP guided by traditional C-arm X-ray machine.

The sialyl Lewis X (SLex) antigen encoded by the FUT7 gene is the ligand of endotheliam-selectin (E-selectin).The combination of SLex antigen and E-selectin represents an important way for malignant tumor metastasis.In the present study,the effect of the SLeX-binding DNA aptamer on the adhesion and metastasis of hepatocellular carcinoma HepG2 cells in vitro was investigated.Reverse transcription-polymerase chain reaction (RT-PCR) and immunofluorescence staining were conducted to detect the expression of FUT7 at both transcriptional and translational levels.The SLex expression in HepG2 cells treated with different concentrations of SLeX-binding DNA aptamer was detected by flow cytometry.Besides,the adhesion,migration,and invasion of HepG2 cells were measured by cell adhesion assay,and the Transwell migration and invasion assay.The results showed that the FUT7 expression was up-regulated at both mRNA and protein levels in HepG2 cells.SLeX-binding DNA aptamer could significantly decrease the expression of SLex in HepG2 cells.The cell adhesion assay revealed that the SLeX-binding DNA aptamer could effectively inhibit the interactions between E-selectin and SLex in the HepG2 cells.Additionally,SLeX-binding DNA aptamers at 20 nmol/L were found to have the similar effect to the monoclonal antibody CSLEX-1.The Transwell migration and invasion assay revealed that the number of penetrating cells on the down-side of Transwell membrane was significantly less in cells treated with 5,10,20 nmol/L SLeX-binding DNA aptamer than those in the negative control group (P<0.01).Our study demonstrated that the SLeX-binding DNA aptamer could significantly inhibit the in vitro adhesion,migration,and invasion of HepG2 cells,suggesting that the SLeX-binding DNA aptamer may be used as a potential molecular targeted drug against metastatic hepatocellular carcinoma.

The Grainyhead-like 3 (GRHL3) is involved in epidermal barrier formation,neural tube closure and wound repair.Previous studies have suggested that GRHL3 has been linked to many different types of cancers.However,to date,its effects on human colorectal cancer (CRC) has not been clarified yet.Our microarray analysis has indicated predominant GRHL3 expression in CRC.The purpose of this study was to investigate the expression and significance of GRHL3 in CRC tumorigenesis using CRC tissues and paired paracancerous tissues,as well as using distinct CRC cell lines (HT29 and DLD1).We observed increased GRHL3 expression at both mRNA and protein levels in CRC tissues and CRC cell lines using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting.Moreover,silencing GRHL3 with siRNA could suppress CRC cell proliferation,viability and migration in vitro.We also found that knockdown of GRHL3 could promote cell cycle arrest at G0/G1 phase in HT29 cells and DLD1 cells,and induce cell apoptosis in HT29 cells.Together,our study revealed the down-regulation of GRHL3 in vitro could inhibit CRC cell activity and trigger cell cycle arrest at G0/G1 phase and apoptosis.

Anterior cervical fusion surgery is the first choice for spine surgeons in the treatment of cervical spine diseases. It has significant effects in treating cervical degenerative diseases, trauma and tumors and other cervical diseases. In anterior cervical fusion, it is necessary to use a distractor to properly distract the intervertebral space, so as to fully expose and relieve the compressive factors, restore the physiological height, curvature and stability of the lesion segment, and achieve the best surgical effect. However, there is currently no consensus on the standard distraction height for the intervertebral space during anterior cervical surgery. This article reviewsed the progress of intervertebral space height in anterior cervical fusion from three dimensions:the relationship between intervertebral space height and cervical disc degeneration mechanism, the selection of intervertebral space height during operation, the recovery of intervertebral space height and the postoperative effect, so as to provide theoretical basis and reference for spinal surgeons when performing intervertebral distraction during operation.

OBJECTIVE:
To investigate the hemodynamic effect of Shen-Fu Injection (, SFI) in early volume resuscitation treated septic shock patients by monitoring pulse indicator continuous cardiac output (PICCO).
METHODS:
All septic shock patients admitted in the Intensive Care Unit of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from January 1st, 2014 to December 31th, 2015, were reviewed, and totally 65 were enrolled in this study. They were assigned to SFI group (33 cases) and control group (32 cases). All 65 patients underwent conventional treatment mainly including volume resuscitation, antibiotics and vasoactive drugs therapy. The patients of the SFI group received additional 100 mL of SFI intravenously every 12 h. In all 65 patients, the PICCO arterial catheter and vein catheter were implanted within 1 h after the diagnosis of septic shock. In the course of early volume resuscitation, hemodynamic data of patients were recorded by PICCO monitor at 0, 12, and 24 h after the catheter implantation.
RESULTS:
The hemodynamic indices of the two groups showed no significant differences at the beginning of 0 h (P>0.05). At 12 and 24 h, the hemodynamic indices of SFI group were significantly improved in comparison with the control group (P<0.05), including cardiac index (CI), global end diastolic volume index (GEDI), mean arterial pressure (MAP) and heart rate (HR). In addition, there was no significant change of extra-vascular lung water index between the two groups (P>0.05).
CONCLUSION
SFI significantly improved hemodynamic indices such as CI, GEDI, MAP and HR in early volume resuscitation treated septic shock patients.
