ObjectiveTo observe the different mode of administration of lidocaine on hemodynamic effects during self-retaining laryngoscope.Methods75 adult patients,underwent selective operations of removal and biopsy of the vocal polype,epiglottis or laryngeal tumor via self-retaining laryngoscope under general anesthesia,were randomly divided into three groups,with 25 cases for each.Group Ⅰ was the control group; Group Ⅱ was the throat spraying group;Group Ⅲ was the intravenous drug group.The incidence of irritating cough and the changes of mean arterial pressure(MAP) and hear rate(HR) were observed during operations.ResultsThe incidence of irritating cough in group Ⅱ was lower than in group Ⅰ and group Ⅲ ( all P ＜ 0.05 ).MAP,HR in group Ⅱ was also lower than that in group Ⅰ and Ⅲ during extubation( all P ＜0.05).However there were no significant differences on MAP,HR between group Ⅰ and group Ⅲ during extubation( all P ＞ 0.05 ).ConclusionLidocaine spraying on larynx could alleviate irritating cough and had significant preventive effect on cardiovascular response,and the effect in this method was superior to intravenous injection.

The achievement of Nongzheng Quanshu in area of herhalogical textual research was illustrated in this paper. Nongzheng Quanshu recorded the information of 159 kinds of cultivated plants and 473 kinds of wild plants. It also quoted many contents from lots of ancient agriculture hooks related in herbalogical literature. Many agriculture researchers were encouraged to have done much work in area of herhalogical textual research It also included the materia medica hook Jiuhuang Bencao and Yecaipu therein and promoted their delivery.

Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.

The achievement of Qimin Yaoshu in the area of herbalogical textual research was illustrated in this paper. Qimin Yaoshu quoted and keeped many contents from ancient agriculture books related in herbalogical literature. It also recorded the information of lots of tropical and subtropical plants. The author bringed forwarded many experiences indistinguishing plants and clarified some long last confused or wrong opinions. The studying philosophy and methods of the authors gave us much enlightenment in our herbalogical textual research. It should be taken into account when the herbalogical textual research was carried out.

Numbering quantities of medical equipment is studied based on Queueing Theory, which can provide a useful and applicable tool for study on medical equipment numbering.

Background Protein kinase B (Akt) is the center of multiple cellular signaling pathways,and it participates in the regulation of cell function,such as proliferation,migration,and metabolism of cells.Phosphoinositide 3-kinase (PI3K) promotes activation of Akt and therefore triggers many signal pathways.PI3K inhibitor can silent Akt,but whether it can affect the biological behavior of lens epithelial cells (LECs) during the posterior capsular opacity (PCO) is worthy of investigation.Objective This study was to explore the effect of LY294002,a PI3K inhibitor,on Akt activation in human LECs.Methods Human LECs strain,HLEC-B3 cells,were cultured and passaged.The cells were incubated to 96-well plate for 24 hours,then LY294002 was added with the final concentration at 0,10,20,30,40,50,60,70,80 μmol/L,respectively.After incubation for 24 hours,cell counting kit-8 (CCK-8) was used to detect the inhibitory rate of cell proliferation.Transforming growth factor-β2 (TGF-β2) of 10 μg/L was added in the medium of cells as TGF-β2 group,TGF-β2 + LY294002 (20 μmol/L) was used to coculture the other group of cells,and the cells without TGF-β2 and LY294002 served as the control group.Phosphorylation of Akt (p-Akt) in the cells was detected by laser scan confocal immunofluorescence microscope.The expression level of p-Akt was evaluated using Western blot.Results CCK-8 assay showed that the A value of the cells was gradually reduced with the increase of LY294002 concentration (Fgroup =9.72,P =0.00),but the A value was significant raised along with the lapse of time (Ftime =1737.54,P=0.00).Confocal immunofluorescence revealed that a little of p-Akt was expressed in the control cells.After induced by TGF-β2,lots of red fluorescence of p-Akt was seen in cells around the cell membranes.But in the TGF-β2+LY294002 co-culture cells,the fluorescence of Akt was much weaker.Western blot showed that the expression level of p-Akt was 0.91±0.08,1.48±0.13 and 0.95±0.19 in the control group,TGF-β2 group and TGF-β2 +LY294002 group,respectively,with a significant difference among the three groups (F =15.04,P =0.00).Conclusions LY294002 can inhibit the activation of Akt induced by TGF-β2.LY294002 may have utility in the prevention and treatment of PCO.
