Chinese Journal of Anesthesiology 1994;0(03):-
Objective To determine the sites of action of propofol and isoflurane on somatosensory pathway using median nerve somatosensory evoked potential(MnSSEP) .Methods Twenty-six ASA I - II patients aged 20-50 yrs were randomly divided into two groups: I propofol group( n = 13) and H isoflurane group( n = 13) .In propofol group patients received propofol infusion at a rate of 10 mg?kg-1?h-1 .Oxygen was administered via mask and respiration was assisted or controlled to maintain SpO2 at 96%-100% and PETCO2 at 35-45 mm Hg. The propofol infusion was continued until the patient failed to respond to verbal command. Six minutes later if the patient was still breathing spontaneously, the rate of propofol infusion was increased to 20-40 mg?kg-1?h-1 . In isoflurane group anesthesia was induced with propofol 2 mg ? kg-1 and intubation was facilitated by succinylcholine and anesthesia was maintained with isoflurane inhalation and intermittent iv boluses of vecuronium. The end-tidal isoflurane concentration was maintained at 0.5,1.0 and 1.5 MAC. Each concentration was maintained for 15 minutes. MAP, HR, SpO2,PCTCO2, T0(naso-pharyngeal) and BIS were continuously monitored. MnSSEP( Viking IV D type) was measured and recorded before induction of anesthesia(baseline) and in propofol group when patients became unconscious and apneic; in isoflurane group when end-tidal isoflurane reached 0.5,1.0 and 1.5 MAC.Results In group I there was no change in both latencies and amplitudes of N9 and N13'.With increasing infusion rate, propofol gradually prolonged the latencies and decreased the amplitudes of N60, P45, N35, N20 and P25 waves. In isoflurane group there was no change in the latencies and amplitudes of N9. There was no change in the latencies of N13', but the amplitudes decreased at 1.0 and 1.5 MAC. With increasing concentration, isoflurane gradually prolonged the latencies and decreased the amplitudes of P45, N60, N35, N20 and P25 waves. At 1.5 MAC the inter-peak latencies between N13'-N20 and N13'-P25 were prolonged. Conclusions The sites of action of different infusion rates of propofol and different concentrations of isoflurane are different on somatosensory pathway. The higher the doses, more widespread are the sites of action.
4.Research progress of miR-451 in tumor
Journal of International Oncology 2014;41(12):887-890
MicroRNA-451 (miR-451) is significantly lowly expressed in glioma,gastric cancer,colorectal cancer,liver cancer and other tumor tissues.Upregulation of miR-451 can significantly inhibit tumor cell proliferation,invasion and metastasis as well as increasing tumor cell apoptosis and improving radiotherapy and chemotherapy sensitivity and other biological effects.
5.Analysis on the expression of Smac and Survivin in precancerous lesions of gastric ulcer
International Journal of Laboratory Medicine 2017;38(17):2406-2408
Objective To investigate the expression of pro-apoptotic factor (Smac) and Survivin in gastric ulcer tissue.Methods Selected the 80 cases of gastric ulcer patients as the research object in the first people′s hospital of neijiang,in which no precancerous lesions of 40 cases of gastric ulcer (N group),40 cases of precancerous lesions of gastric ulcer(Y group),two groups of patients were Smac mRNA and Survivin mRNA were detected by using PCR method,immunohistochemical SP method of Smac and Survivin in specimens of table detect.Gastric ulcer patients were treated by triple therapy,and the apoptosis index was detected by TUNEL.Results Smac in N group(++) and (+++) in the expression accounted for 82.5% was higher than that in Y group accounted for 47.5%,Survivin in group N (++) and (+++) in the expression accounted for 15.0% was significantly lower than Y group accounted for 35.0%;And Smac mRNA in the N group relative expression the amount was significantly higher than that of Y group,while the expression of Survivin mRNA in the N group were significantly lower than Y group;N group the apoptosis index of the triple therapy after treatment than before treatment significantly decreased,the difference was statistically significant(P<0.05).Conclusion The clinical application of Smac and Survivin can be used as an auxiliary diagnostic index for the diagnosis of precancerous lesions in patients with gastric ulcer.Patients with gastric ulcer without precancerous lesion treated by triple therapy which can effectively control the apoptosis index of patients,improve the survival rate of patients.
6.The use of ultrasonically activated scalpel in modified radical mastectomy for breast cancer after neo-adjuvant chemotherapy
Journal of Endocrine Surgery 2012;06(2):106-108
ObjectiveTo discuss the clinical value of ultrasonically activated scalpel(UAS) in breast cancer patients who underwent 2-3 cycles of neo-adjuvant chemotherapy by comparing UAS and electric knives (EI) in modified radical mastectomy. MethodsFrom Jun.2009 to Aug.2011, 52 breast cancer patients taking 2-3 cycles of neo-adjuvant chemotherapy underwent modified radical mastectomy in our hospital. Among them, UAS group included 23 patients, and EI group included 29 patients.The 2 groups were compared in terms of the operation time, intraoperative blood loss, postoperative drainage tube duration, postoperative hospital stay, the number of lymph nodes retrieved, and the volume of subcutaneous hydrops.ResultsBetween the 2 groups, the difference of intraoperative blood loss and postoperative drainage tube duration had statistical significance(P <0.01 ).The difference of operation time, hospital stay, and subcutaneous hydrops had statistical significance ( P < 0.05 ).The difference of the number of lymph nodes retrieved had no statistical significance ( P > 0.05 ).ConclusionThere are good curative effects for breast cancer patients undergoing modified radical mastectomy by UAS and axillary lymph node dissection after neo-adjuvant chemotherapy, which is consistent with the conception of fast track surgery.

Journal of Chinese Physician 2016;18(12):1761-1763
On June 20,2014 in Washington for a meeting of the heart,a think-tank.As a call to action,the meeting to define the cardiovascular disease~ prevention and control of new mode and method,to help solve the problem of merging high metabolic risk of cardiovascular disease.More than 20 representative groups participate in the discussion and meet the following consensus that metabolic syndrome is a complex pathophysiological state,is a process of gradual change,consisting of a series of known and unknown risk factors,and is associated with the severity of the disease.Treatment is the ideal mode of the metabolic syndrome,before the disease can accurately determine risk,identify the subtypes of disease,and identify the different stages of the disease,in order to better carry out prevention and treatment of cardiovascular disease.This new mode of prevention and control of determination needs establishment of consensus,and sustainable development of this control mode,the mode of authentication,in the future continue to optimize the mode.
10.Role of PPAR? in Pathogenesis of Colorectal Cancer
Chinese Journal of Bases and Clinics in General Surgery 2003;0(04):-
Objective To investigate the role of PPAR? in the pathogenesis of colorectal cancer. Methods Literatures about PPAR? and the pathogenesis of colorectal cancer were reviewed and analyzed.Results PPAR? is expressed in the nucleuses of glandular epithelia lining colon and rectum. It is normally suppressed by wild-type adenomatous polyposis coli (APC) but is up-regulated by enhanced ?-catenin/T cell factor-4 (TCF-4) binding to TCF-4-responsive elements in the PPAR promoter when an inactivating APC mutation occurs, which indicates PPAR is a potential downstream target of the APC/?-catenin/TCF-4 signaling pathway in colorectal cancer. Consistent with PPAR’s role as an APC/?-catenin/TCF-4 target, some studies reported that PPAR mRNA is frequently overexpressed in colorectal cancers of both humans and rodent animals, which indicates that PPAR is relevant to the tumorigenesis of colorectal cancer. Conclusion PPAR? is closely related with the pathogenesis of colorectal cancer.
