Objective To observe the patients hemodynamic reactions to the different stimula-tions under different blood concentrations of propofol with remifentanil.Exerting the response surface methodology,the half of the maximum effective concentration of propofol and the interaction index of propofol with remifentanil were calculated.Methods A total of 120 patients for scheduled abdominal surgery,randomly divided into 12 groups(n = 10).TCI 12 different concentration combinations of propofol with remifentanil,also the the hemodynamic reactions to harmful stimulations of intubation and incising were observed.The data were analyzed by responding surface analysis.Results The in-teraction index of propofol and remifentanil under intubation was 0.523 0±0.223 7,that under inci-sing 0.361 3±0.148 4,half of the maximum effective concentration of propofol for intutation and in-cising was (6.878 7 ± 1.832 1 ) μg/ml and (4.41 1 6 ± 0.902 5 ) μg/ml respectively. Conclusion Propofol and remifentanil have a synergistic inhibitory effect on harmful cardiovascular reaction among Chinese.During the endotracheal intubation,the requirements of half of the maximum effective concentration of propofol and intensity of the synergy with remifentanil are greater than those during the incising.

Objective To study the serum immunoglobulin IgG,IgM,IgA and complements C3,C4 level changes in hand foot and mouth disease (HFMD) combined with acute flaccid paralysis (AFP).Methods The cases were divided into three groups in this study,including 30 cases of HFMD,30 cases of HFMD combined with AFP,and 30 cases of healthy(normal control group).Immunoturbidimetric assay was used to test the level changes of IgG,IgM,IgA,and complements C3,C4.Results The IgG,IgA,C3 and C4 in HFMD combined with AFP group were (5.49±1.04) g/L,(0.39±0.27) g/L,(0.65.±0.19) g/L and (0.16.±0.11) g/L respectively,lower than those in HFMD group((7.07± 1.63) g/L,(0.55±0.32) g/L,(0.97.±0.18) g/L,(0.23.±0.09) g/L) and normal control group((9.58±1.42) g/L,(0.81±0.33) g/L,(1.28.±0.25) g/L,(0.34.±0.16) g/L),there were statistically significant differences among groups(F=12.04,1.84,1.65,1.29;P=0.031,0.020,0.018,0.025).However,the expression of IgM in HFMD combined with AFP group was (1.34±0.26) g/L,higher than that in HFMD group((1.02±0.29) g/L) and normal control group ((0.76±0.28) g/L),the difference was statistically significant(F=3.62,P=0.014).Conclusion HFMD combined with AFP exists severe humoral immune dysfunction,which provides a theoretical evidence for the prevention and treatment of HFMD combined with AFP.

After percutaneous coronary intervention (PCI) was performed,since CHD risk factors still exist, coronary restenosis rate remains high.Therefore, self-management after PCI is very important.The present article made a review on current condition and research progress of self-management in patients after PCI, aiming at providing reliable evidence for rehabilitation after PCI.

Objective:To investigate the efficacy of Vitreoretinal surgery for retinal detachment due to macular hole in high myopia. Methods:20 cases( 20 eyes) of retinal detachment due to macular hole in high myopia from Dec. 2000 to Apr. 2004 were analysed retrospectively. 3 cases were male and 17 were female, with a following up of 2 to 30 months (15 months in average). The Pars Plana Vitrectomy with long acting gas or silicon oil tamponade were used. The patients were kept face down at least 7 days after the surgery. Results:5 eyes used silicon oil and the others used gas tamponade. The successful rate of retinal reattachment was 80% ( 16/20) with one procedure in a month after the surgery . There were 4 cases of retinal redetachment in the follow-up duration, among them 3 cases used gas and one used silicon oil tamponade. All of them refused to accept another surgery. There were 3 eyes ( 15%) of the best corrected visual acuity greater than or equal to 0.05 before surgery and 11 eyes ( 55%) equal to or greater than 0.05 after the surgery. There was a significant difference between them(P= 0.0386 ). The main complications were slight retinal bleeding in 3 eyes ( 15%); second glaucoma in 2 eyes (10 %); nuclear cataract in 4 eyes ( 20%). Conclusion:Vitreoretinal surgery for retinal detachment with macular hole is available to improve visual acuity in high myopia.

KRAS mutation is one of the most frequent driver gene mutations found in patients with non-small cell lung cancer (NSCLC). KRAS-mutant NSCLC is highly heterogeneous. Various mutation types and different co-mutational signatures affect tumor biological behavior and therapeutic responses. NSCLC patients with KRAS mutations could relatively benefit from immunotherapy, while the effects of KRAS mutations on chemotherapy are still controversial. The treatment methods of KRAS-mutant lung cancer have followed the therapy of NSCLC without driver gene mutation for a long time. With the introduction of novel KRAS G12C inhibitors in the clinic, the therapeutic landscape has begun to change and has made the preliminary advance, and the combined therapies resulted in encouraging signals of efficacy both in preclinical and early phase trials. This paper reviews the biological and clinical characteristics as well as the latest treatment progress of KRAS-mutant NSCLC.

Objective To study the influence of electro-acupuncture(EA)at Zusanli points(足三里穴) on the apoptosis of thymocytes in rats with abdominal infection and its mechanism.Methods A total of 40 Sprague-Dawley(SD)rats were randomly divided into four groups,including normal control group,model group,non-acupoint group and Zusanli group.The abdominal infection model of rat was made by cecal ligation and puncture(CLP).After abdominal cavity infection for 36 hours,the apoptosis of thymocytes was observed under electron microscope and light microscope,and the apoptosis ratio of thymocytes was determined by Annexin V-PI method with flow cytometry technique.The content of Bcl-2 protein of thymocytes and concentration of corticosterone in plasma were determined.Results Abdominal infection resulted from CLP could significantly increase the apoptosis of thymocytes and lead to the typical histopathological changes of apoptosis of thymocytes under electron microscope and light microscope.Apoptosis ratios of thyrnocytes in model group[(44.7?3.3)%],non-acupoint group[(42.7?3.0)%]and Zusanli group[(32.6?3.3)%] were significantly higher than the ratio in the control group[(21.2?2.3)%,all P0.05).Abdominal infection resulted from CLP also could reduce the content of Bcl-2 protein of thymocytes.The content of Bcl-2 protein of thymocytes in model group(71.2?5.6),non-acupoint group(73.5?5.9)and Zusanli group(82.4?6.8) were significantly lower than normal control group(95.3?6.3,all P
