| 1 | Multi-belts coil longitudinal guided wave magnetostrictive transducer for ferromagnetic pipes testing显示文摘A new ultrasonic transducer with multi-belts coil for generating and receiving longitudinal guided wave in ferromagnetic material pipes is proposed.The theory backgrounds and transduction principle of the proposed transducer are presented and ana- lyzed.To verify the performance of the transducer,several experiments are performed.The performance of inspecting crack, frequency-tuned characteristic,effect of bias static magnetic field and dynamic magnetic field,lift-off effect and effect of the period number of the exciting current are investigated.The results show that the proposed coils not only could tune the center frequency but also could improve the amplitude and signal-to-noise(SNR)of the detected signals.Bias static magnetic field and dynamic magnetic field are two important factors influencing the amplitude of the longitudinal guided wave.The amplitude of the longitudinal guided wave is exponentially decreased versus the lift-off distance of the transmitter and receiver.Period number of excitation signal could influence the amplitude and wave width of the ultrasonic wave.The proposed transducer could easily control the wave modes and would be a better choice for pipes’monitoring and inspection compared to traditional single-belt coil transducer. | HAO KuanSheng HUANG SongLing ZHAO Wei WANG Shen | 2011 | Science China(Technological Sciences)2011，54，2： | 5 |

| 14 | The Regulating Effect of CCK and Gastrin on Apoptosis of Bile Duct Carcinoma Cells显示文摘Objective:Probe into the influence and the mechanisms of CCK and gastrin on the apoptosis of bile duct carcinoma cells. Methods:By taking beauvericin as the revulsant to the apoptosis of bile duct carcinoma cells, the influence of CCK and gastrin on the apoptosis of bile duct carcinoma cells was investigated by using the teehniques such as TUNEL fluorescent staining, stream mode cell detecting instrument and reverse bcl-2 oligonucleotide. Techifiques of immunohistochemistry, in situ hybridization,flow cytometry(FCM),RT-PCR were used to study the roles of apoptosis-related genes bcl-2 and bax Results:After beauvericin 40 μM worked for 12 h, the survival rate of QBC939 bile duct carcinoma cells was decreased by 35%-40%.About 80% of the bile duct carcinoma cells showed various degrees of apoptosis.CCK and gastrin could upregulate the threshold value of the apoptosis of bile duct carcinoma cells, which could be inhibited by L60,L18 and reverse bcl-2 oligonucleotide. In terms of both transcription and translating levels,CCK and gastrin could obviously promote the genetic expression of bel-2,but had no influence on the genetic expression of bax. Addition of CCK-A receptor or CCK-B/gastr in receptor antagonist could remarkably inhibit the expression of bel-2 boosted by gastrin-17 and CCK-8S. Conclusion:CCK and gastrin inhibited the apoptosis of bile duct carcinoma cells through upregulating the genetic expression of bcl-2.Theoretically, this research has expanded our understanding to the mechanism of CCK and gastrin in controlling the growth of tumors, enriched our view to the mechanism of apoptosis of alimentary tract tumors, and has provided a new thinking for the assistant treatment to bile duct carcinoma cells as well. | MA Kuansheng, ZHANG Fengshen, HE Zhenping, DONG Jiahong The Institute of Hepatobiliary Surgery of PLA, Southwest Hospital, Third Military Medical University, Chongqing 400038, China | 2002 | The Chinese-German Journal of Clinical Oncology2002，1，1： | 0 |
| 15 | A clinical study on salvage hepatectomy for treating recurrent liver cancer after radiofrequency ablation显示文摘Objective We studied the efficacy of salvage hepatectomy for treating recurrent hepatic cancer after radiofrequency ablation(RFA). Methods A retrospective analysis of 67 patients who had recurrent liver cancer after RFA treatment and received salvage hepatectomy in the Department of Hepatobiliary Surgery, Southwest Hospital, Third Military Medical University(China), from January 2006 to January 2014, was performed. The analysis included patient gender, age, hepatitis type, alpha-fetoprotein(AFP), and TNM stage prior to RFA and salvage hepatectomy, overall survival rates, and tumor-free survival rates after salvage hepatectomy. Results Among the 67 patients, there were 57 cases of hepatitis B, two cases of hepatitis C, and eight cases did not have hepatitis. AFP levels in patients ranged from 3 to 4521 ng/m L(median 33 ng/m L). Before RFA, 54 cases were stage I tumors, and 13 were stage II tumors. Tumor sizes varied from 0.82 to 4.83 cm(median 3.0 cm). In 20 cases, one RFA was performed, and for 47 cases, RFA was repeated. RFAablated region diameters ranged from 3.8 to 5.2 cm(median 4.5 cm). The interval between the salvage surgical resection and RFA was 3–37 months. Before salvage hepatectomy, 23 stage I tumors, 12 stage II tumors, and 32 stage III tumors were present(size ranged 4.83–11.84 cm; median 6.3 cm). For salvage hepatectomy, laparotomy was performed for 56 cases, and laparoscopy was performed for 28 cases. Inflow clamping was performed for 39 cases(15–45 min). Surgery was 219–370 min and intraoperative blood loss was 100–2100 m L. For 13 cases, intraoperative blood transfusion was required. Tumor pathological data revealed 31, 35, and 1 poorly, moderately, and well differentiated tumors, respectively. No patients died due to operative complications, and hospital stays were 8–10 days. Overall and tumor-free survival rates were 85% and 79% for 1 year, 50% and 20% for 3 years, and 39% and 19% for 5 years, respectively. KaplanMeier analysis and Cox regression confirmed that tumor number and size prior to salvage liver cancer were risk factors affecting survival. Conclusion Patients who received RFA to treat early-stage liver cancer with postoperative recurrent stage I tumors have satisfactory outcomes with salvage hepatectomy. | Qing Xiong Xiaobin Feng Jun Yan Feng Xia Xiaowu Li Kuansheng Ma Ping Bie | 2015 | Oncology and Translational Medicine2015，1，6： | 0 |
| 16 | Preoperative Assessment of Abdominal Adipose Tissue to Predict Microvascular Invasion in Small Hepatocellular Carcinoma显示文摘Background and Aims:Microvascular invasion(MVI)affects recurrence after treatment of small hepatocellular carcinoma(sHCC)of≤3 cm in size.The present study aimed to investigate whether abdominal subcutaneous adipose tissue(SAT),visceral adipose tissue(VAT),and intermuscular adipose tissue(IMAT)are associated with MVI in patients with sHCC.Methods:A total of 124 patients with pathologicallyconfirmed sHCC diagnosed on surgical resection at the First Hospital Affiliated to Army Military University were recruited and divided into two groups according to MVI classification criteria(i.e.,MVI-positive or MVI-negative).The SAT,VAT,and IMAT areas at the lumbar 3 vertebral level were imaged with abdominal computed tomography and measured using ImageJ software.Their association with MVI in sHCC was analyzed.Results:Of the 124 patients with sHCC,67 were MVIpositive and 57 were MVInegative.Univariate analysis revealed a significant difference in the abdominal VAT and SAT between the MVI-positive and MVI-negative groups(p<0.05),with an area under the receiver operating characteristic curve of 0.76 and 0.65,respectively.Conclusions:The results of this study suggest that the areas of abdominal SAT and VAT are of significant clinical value because they can effectively predict the MVI status in patients with sHCC. | Zongqian Wu Hong Lu Qiao Xie Jie Cheng Kuansheng Ma Xiaofei Hu Liang Tan Huarong Zhang Chen Liu Xiaoming Li Ping Cai | 2022 | Journal of Clinical and Translational Hepatology2022，10，2： | 0 |
