Chongqing Medicine 2014;(4):448-450
Objective To investigate the feasibility and safety of laparoscopic myomectomy in patients with large-diameter hyste-romyoma .Methods A retrospective analysis of data from 37 patients in which the uterus were larger than 14-week gestational size and the diameter of myoma was ≥7 cm treated by laparoscopic myomectomy from January 2007 to December 2011 in our hospital was conducted .The outcome of the operation were compared with that in 53 large-diameter hysteromyoma cases by abdominal sur-gery .Results 37 patients were carried out laparoscopic surgery in which 28 cases were treated successfully by total laparoscopy , and small abdominal incision was made in 6 cases .3 of the cases converted to open surgery .The ureteral abdominal fistula was ob-served in 1 case ,which was cured by a reoperation of abdominal ureteral anastomosis .All patients were successfully cured and re-tained the uterus .The cases converted to open had no significant correlation with the patient′s age ,the fibroids size ,fibroids num-ber ,operative time and blood loss volume(P>0 .05) .Compared with the laparotomy group ,the operative time ,blood loss and post-operative morbidity were similar between groups (P>0 .05) .Postoperative recovery times after laparoscopic group were less than the control group(P<0 .05) .In the follow-up of 51 months(18 to 78) ,the laparoscopic myomectomy is equally effective with the laparotomy group in the number of cases of the postoperative normal menstruation and the postoperative spontaneous pregnancy . There were no statistically significant differences between the two groups (P>0 .05) .Conclusion Laparoscopic myomectomy in pa-tients with large-diameter hysteromyoma is safe and feasible while excellent surgical skills were required for a successful surgery .
2.Increased expression of endothelin receptors in human cirrhosis--relationship with splanchnic hemodynamics.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2002;22(1):37-41
The purpose of the present study was to assess the correlation that likely exists among increased portal pressure (Pp), portal blood flow quantity (Qp) and ETA and ETB receptor mRNA expression in human cirrhosis. In situ hybridization and reverse-transcription polymerase chain reactions (RT-PCR) were performed to determined the expression of ETA and ETB receptor mRNA in liver tissues from traumatic subjects (n = 10) and cirrhotic patients (n = 15) in whom hepatic hemodynamic values were measured. The expression of the two transcripts was significantly higher in liver samples of cirrhotic patients than in those obtained from traumatic subjects. It has shown that ETA receptor mRNA predominantly located in hepatic stellate cells (HSCs) and vascular smooth muscle cells of intrahepatic arteries and portal veins, ETB receptor mRNA in HSCs, sinusoidal endothelial cells and Kuppfer cells. There was a highly significant direct relationship between ETA and ETB receptor mRNA and Pp and Qp in cirrhotic patients. It suggests that liver paracrine endothelin system may be overactivated in human cirrhosis accompanied with increased expression of ETA and ETB receptor mRNA which may play an important role in the pathogenesis and maintenance of splanchnic hyperdynamics.

3.Autophagy and energy metabolism
Chinese Journal of Endocrinology and Metabolism 2014;30(4):349-352
Eukaryotic cells maintain cellular homeostasis by regulating the process of protein degradation and organelle turnover.Autophagy is a ubiquitin-like degradation process,and plays an essential role in cellular development,differentiation,and elimination of damaged organelles and protein.Previous studies mostly focused autophagy on tumor and neurodegenerative diseases,whereas studies about autophagy and energy remain not clear.Since 2009,an increasing number of studies have showed light on the importance of autophagy in regulating lipid metabolism.The review focuses on the relationship between autophagy and differentiation of adipocytes,lipogenesis,and lipolysis.
4.The application of HER2 to pancreatic cancer treatment
Chinese Journal of Hepatobiliary Surgery 2013;19(10):796-800
Pancreatic cancer (PC) is known for its high malignancy and poor prognosis.Furthermore,PC patients have little chance to receive an operation,and chemotherapy is not always an ideal alternative.More effective treatment is necessary because over the last two decades,the morbidity and the mortality of PC has risen continuously.Some new PC treatments involve HER2,a transmembrane protein that has oncological significance.The amplification of its gene or over expression of itself can cause malignant proliferation,suppression of apoptosis,and angiogenesis in PC.Its potential can be seen with HER2 targeted medicines including the clinically used Trastuzumab,but also with bispecific antibody,tyrosine kinase inhibitors,and more.This article will review the application of these new developments.

Effects of epidural block on stress response during eardiopulmonary bypass were studied. Twenty patients, undergoing open heart surgery with cardiopulmonary bypass, were randomly divided into two groups:the control group with intravenous high-dose fentanyl and enflurane inhalation (1%-1.5%);the tested group with epidural block and enflurane inhalation (0.5%-1%). The plasma norepinephine (NE) and epinephrine (E) concentrations were higher in group control than those in tested group during and after CPB,even at the end of operation (P
6.The choice of myocardial revascularization of left main and/or three-vessel disease based on SYNTAX and EuroSCORE
Chinese Journal of Thoracic and Cardiovascular Surgery 2016;32(5):309-312
In recent years,we have progressed in the treatment of coronary heart disease by a large margin,which improved the prognostic condition of coronary heart disease patients,conspicuously.Whereas,we have still harbored discordant reservations about what fuels in the theraputic stragety of the left main and/or three vessel disease which causes acute myocardial infarction and the sudden cardiac death,for the time being,internationally.EuroSCORE and SYNTAX Score are both widely accepted in probing in the theraputic stragetic credits,internationally.Hence,we are about to review the twin credits system on the optional directive meaning of the strategy of myocardial revasscularization in the left main and/or three vessel patients.
