This study is to investigate the effect of ethyl gallate on invasion capabilities and its mechanism of breast cancer MDA-MB-231 cells. Using cell adhesion and transwell assay, separately, the effects of ethyl gallate on the invasion of MDA-MB-231 cells were measured. The Akt-NF-κB signal pathway protein expressions were analyzed with Western blot. Also, the mRNA levels of MMP-9 and MMP-2 were analyzed by RT-PCR. Ethyl gallate inhibited the abilities of motility, adhesion and invasion of breast cancer MDA-MB-231 cells in vitro (P<0.05), inhibited the mRNA levels of MMP-9, MMP-2, phosphorylation of AKt and protein expression of NF-κB. It is concluded that ethyl gallate can inhibit the abilities of invasion of breast cancer in vitro by inhibiting the mRNA levels of MMP-9/MMP-2, phosphorylation of Akt and protein expression of NF-κB.

Objective To assess the value of ultrasonography(US)in the diagnosis of pancreas endocrine tumors(PET).Methods Thirty-six patients with PET confirmed by surgery and pathology were retrospectively reviewed.Results There were 37 PET in 36 patients,among which 33 tumors in 32 cases were detected bv US,four tumors were missed on US and the detection rate was 88.9%(32/36).The tumor size was 1.0 cm×0.8 cm～12.9 cm× 11.3 cm.Among 12 cases of equal to or less than 2 cm,9 tumors were detected and the detection rate was 75.0%.PET presented mostly hypoechogenicity(78.8%),other 7 cases presented mixed-echogenicity.Color Doppler US was performed on 12 cases and 11 tumors showed color blood signals.Abundant flow signal was detected in 8 tumors(66.7%).PET were found in pancreatic head (n=11),neck(n=2),body(n=6)and tail(n=11),which was diagnosed correctly in 30 cases (81.1%).Conclusions US is a useful tool in the detection and diagnosis of PET.

Objective To investigate the relationship between hemodynamic parameters from quantitative analysis of contrast-enhanced ultrasonography (CEUS) on hepatocellular carcinoma (HCC) and pathological tumor differentiated grades. Methods Seventy-seven HCC lesions were examinated and off-line analyzed with dynamic images. Quantitative parameters such as slope of decrease to half of peak (SD), increased signal intensity (ISI), area under the curve (AUC) and blood flow coefficient (BF) were acquired, and the standardized values (sISI, sAUC and sBF) included the ratio of parameters from tumor to those from hepatic parenchyma. These quantitative parameters were correlated with tumor grades according to Edmonson criteria. Results There was significant difference (P＜0.05) of SD, AUC and BF, as well as standardized values (sISI, sAUC and sBF) between different grades of HCC. AUC, BF, sISI, sAUC and sBF were negative correlated with differentiated grades, respectively (P＜0.05). Well-differentiated HCC had significantly higher perfusion values than HCC of other grades (P＜0.05). Conclusion Quantitative analysis of CEUS can assess differentiation of HCC indirectly, and might reveal biological behavior of malignant tumors.

OBJECTIVETo investigate the clinical effects of anterior cervical intervertebral space decompression under microscope in treating cervical spondylotic myelopathy in elderly patients.

METHODSFrom June 2009 to March 2012, 43 patients with cervical spondylotic myelopathy were treated with anterior cervical intervertebral space decompression and intervertebral fusion under microscope. There were 26 males and 17 females, aged from 60 to 72 years old with an average of (64.9±3.7) years. Japanese Orthopaedic Association System (JOA) score was from 7 to 12 points with an average of (9.5±1.8) points before operation. The function of nerves was assessed before and after operation according to JOA.

RESULTSAll patients were followed up from 10 to 18 months with an average of (14.7±1.6) months. Postoperative JOA score was (13.81±1.44) points (ranged, 10 to 16), had significantly higher than preoperative (P<0.01). According to the rate of the improved JOA score, 9 cases got excellent results, 26 good, 7 fair, 1 poor.

CONCLUSIONAnterior cervical intervertebral space decompression under microscope for cervical spondylotic myelopathy in elderly patients is safe and effective.

Objective:To systematically evaluate the therapeutic efficacy of tuina therapy for primary insomnia.Methods:Nine Chinese and English databases were searched from the inception to May 2017 to identify randomized controlled trials (RCTs) studying tuina therapy for insomnia.The enrolled articles were all RCTs with tuina as the monotherapy or major therapy in the experiment group,with clear diagnostic criteria for primary insomnia well recognized worldwide or in China,and Pittsburgh sleep quality index (PSQ I) as one of the outcome measures.Two researchers evaluated the risk of bias and quality of the enrolled studies by following Cochrane Handbook version 5.1.0.The meta-analysis was performed by RevMan version 5.3.Results:Eleven studies were included with a total of 1 076 participants.The Western medication adopted in the control groups were benzodiazepine receptor agonists.The studies were all assessed as high risk of bias for blinding since blinding method was unable to be performed due to the specificity of tuina therapy;no study reported the support of fund or potential interest conflict,so they were all rated unclear for selective reporting.The meta-analysis showed that compared with other traditional Chinese medicine therapies,tuina worked more effectively in reducing the PSQI score (MD=-4.11＜0,95％ confidence interval (CI)-6.01 to-2.22,P＜0.0001);compared with oral administration of Western medication,tuina showed more significant efficacy in reducing the PSQI score (MD=-3.42＜0,95％CI-5.19 to-1.66,P＜0.0001).Subgroup analysis showed that head tuina alone showed no significant difference compared with oral administration of Western medication regarding the change of PSQI score (MD=-4.19＜0,95％CI-8.87 to 0.50,P＞0.05);a combination of head and back tuina could more effectively reduce the PSQI score compared with oral administration of Western medication (MD=-2.08＜0,95％CI-3.09 to-1.06,P＜0.0001).Conclusion:Tuina can produce more significant efficacy in treating primary insomnia compared with other traditional Chinese medicine therapies and oral administration of Western medication,especially the combination of head and back tuina.

MTT Colorimetric method is usually applied for measuring the living animal cell number. By changing the reaction temperature and the reaction time as well as the colorimetric wavelength, the improved MTT colorimetric method was established to count the living bacterial cell number. This new method was used to measure the living cell concentration in the process for culturing bacteria PBW1. The results measured by the improved MIT colorimetric method and dilute plate method are similar. Compared with other methods including the dilute plate method, the improved MTT colorimetric method has many advantages such as accuracy, quickness.

Background and purpose:Ara-C is one of the most effective and common agents in the treatment of acute nonlyphocytic leukemia. Telomerase is a unique complex of ribonucleoprotein. It plays an important role in the pathogenesis and development of cancer. In this study, we investigate the changes of mRNA expression of telomerase subunits in HL-60 cells induced by Ara-c and try to come up with a theory that could help to assess the efficacy of Ara-C. Methods:The combinations of various Ara-C concentration and the incubation time were used to treat HL-60. The ratios of apoptotic cell to necrosis cell were determined by flow cytometry and the expressions of telomerase subunits mRNA were evaluated by RT-PCR.Results:① There was no influence on transcription of telomerase subunits gene after HL-60 cells was cultured with 0~0.2ug/ml Ara-C for 12 hours;② 2ug/ml and 10ug/ml of Ara-C could down regulate the expression of hTERT from 0.80+0.07 to 0.50+0.04 and 0.39+0.03, not hTR and hTP1;③ with longer incubation with 10ug/ml of Ara-C, the percentage of apoptosis could be increased. The maximal induction of apoptosis (18.16+4.25%) could be reached at 12hrs treatment of Ara-C, then gradually decreased later on. The rate of necrosis increased with time, the maximal percentage(57.94+12.03%) of necrosis was observed at 48hrs of incubation time with drug. The mRNA level of hTERT gene also decreased along with the cultured time , the lowest value (0.18+0.03) has been documented at 48hrs time point, but not hTR、TP1.Conclusions:① Ara-C could down-regulate the expression of hTERT mRNA in a dose-and time-dependent manner, but not hTR、hTP1;② There might be no relationship between the percentage of apoptosis induced by Ara-C apoptosis and the expression of telomerase hTERT gene mRNA, but a close relationship between necrosis and the expression of hTERT mRNA has been found.
