Objective The purpose of this study was to investigate the preventive effect of flurbiprofen axetil or small-dose ketamine for remifentanil-induced postoperative hyperalgesia. Methods 120 anesthetized patients with ASA ⅠorⅡwere randomly divided into three groups. Group A (40 cases) was given 0.5 mg/kg of ketamine by intravenous injection,and 5μg/(kg.min) vein to maintain,group B (40 cases) was given 100 mg of preoperative flurbiprofen axetil by intravenous injection and group C (40 cases) had no flurbiprofen axetil or ketamine which was served as controls. After the treatment, all groups were given continuous intravenous tramadol controlled analgesia (PCIA) . Results After 1 h, 2 h, 4 h and 8 h, the visual analog scale (VAS) of group C was significantly higher than that of group A and group B ( <0.05);after 24 h, there was no statistically significant difference among the three groups in VAS scores ( > 0.05) . The number of fentanyl analgesia were 25 cases and postoperative 24 h PCIA self-control were (8.6 ±4.2) times, which were more than 7 cases and (3.3 ±2.8) times of group A, and 6 cases and (3.2 ± 2.2) times of group B ( <0.05) . Conclusion The preoperative administration of flurbiprofen axetil or intraoperative continuously administered ketamine is able to prevent the occurrence of remifentanil-induced postoperative hyperalgesia, and it will not affect the patient regained consciousness. The method is safe and reliable,so it is worth promoting and popularizing.

The commissural fibres of hippocampus and dentate gyrus were studied by the method of horseradish peroxidase (HRP) in the guinea pig. The results are as follows:(1) The superior region (CA_1)of hippocampus sends commissural fibres to the same field of the contralateral side.(2) The inferior region (CA_3) of hippocampus sends commissural fibres to all fields of hippocampus and dentate gyrus of the contralateral side.(3) The cells of polymorphic layer of the dentate gyrus send commissural fibres to the dentate gyrus or the inferior region (CA_3) nearby the dentate gyrus of the contralateral side, or perhaps to both of them.(4) The superior region of hippocampus receives commissural fibres which have remarkable degree of symmetry, and this is probably also true of the dentate gyrus, but the inferior region of hippocampus is not likely so.

Objective To investigate the effects of mild pefioperative hypothermia on cellular immune function in patients undergoing surgery for rectal cancer.Methods Fifty ASA Ⅰ or Ⅱ patients aged 30-64 yr undergoing surgery for rectal cancer were randomly divided into 2 groups ( n =25 each):mild hypothermia group and normal body temperature group.Anesthesia was induced with midazolam,fentanyl,etomidate and vecuronium and maintained with propofol,remifentanil and vecuronium.The patients were mechanically ventilated after tracheal intubation.PET CO2 was maintained at 35-45 mm Hg.The venous blood samples were taken from peripheral vein at 1 h before anesthesia (T1 ),at the end of operation (T2),at 24 h after operation (T3),and on 7th day after operation (T4) to measure the serum Th1 and Th2 cytokines levels and Th1/Th2 cytokines balance was observed.Results Compared with the baseline value at T1,the serum Th2 cytokines level was significantly decreased and Th1/Th2 ratio was significantly increased at T4 in normal body temperature group,and the serum Th1 cytokines level and Th1/Th2 ratio were significantly decreased and the serum Th2 cytokines level was significantly increased at T2.3 in mild hypothermia group ( P ＜ 0.05).Compared with normal body temperature group,the serum Th1 cytokines level and Th1/Th2 ratio were significantly decreased and the serum Th2 cytokines level was significantly increased at T2-4 in mild hypothermia group ( P ＜ 0.05).Conclusion Mild perioperative hypothermia can depress cellular immune function in patients undergoing surgery for rectal cancer.

Objective To assess the prevalence and binocular dysfunctional risk factors associated with asthenopia among adult myopes.Methods The study population included 800 adult myopes,a cross-sectional visual parameters that characterize the accommodative:accommodation amplitude (AA),accommodative facility,and accommodative response (fused crossed cylinder-FCC) and binocular function (near and distant horizontal and vertical associated phorias,near and distance negative and positive fusional vergence,near point of convergence,negative and positive relative accommodation (NRA/PRA),stimulus AC/A ratio and stereoacuity) were evaluated when these subjects wore adequate spectacle correction.Results Asthenopia was reported in 24.2％ (194/800) of myopes.The incidence of asthenopia in female (27.8％,128/460) was more than that in male (19.4％,66/340),and there was significant difference (P =0.006).In univariate analysis,the monocular AA,binocular AA,NRA and PRA were significantly associated with asthenopia (P =0.000).In multivariate analysis,low NRA (≤1.25 D),low NRA (≤1.50 D) were significant risk factors for asthenopia (P =0.000,OR =7.644 ;95％ CI 2.913-17.580;P =0.000,OR =5.303;95％ CI 2.822-16.205).Conclusion Preventive measures directed against the binocular dysfunctional risks factors associated with asthenopia may help reduce the prevalence and provide a positive impact on asthenopia.

OBJECTIVETo explore the subcellular localization of ataxin-3 and the effect of polyglutamine (polyQ) expansion mutation on the morphology of mitochondrion, golgi apparatus and endoplasmic reticulum.

METHODSTransient transfection was employed to build cell models expressing wild-type or mutant ataxin-3 proteins. Indirect immunofluorescence was applied to identify markers of organelle membrane. The results were observed under a laser scanning confocal microscope.

RESULTSNo co-localization was observed for ataxin-3 protein and mitochondrial marker TOM20, but the percentage of cells with mitochondrial fragmentation has increased in cells expressing mutant ataxin-3 (P<0.05). No co-localization was observed for ataxin-3 protein and golgi marker GM130, and mutant ataxin-3 did not cause golgi fragmentation. Wide type and polyQ-expanded ataxin-3 both showed partial co-localization with ER marker calnexin. The latter showed more overlap with calnexin, and the overlapping signals were mostly located in the places where aggregates were situated.

CONCLUSIONPolyQ-expanded ataxin-3 protein may indirectly affect the integrity of mitochondria, but may cause no effect on the structure and functions of golgi apparatus. Endoplasmic reticulum may be another place where extended ataxin-3 protein can induce cytotoxicity in addition to the nucleus.

Objective:To explore and validate the targets of Salvia miltiorrhiza in myopia using network pharmacology and molecular docking technology. Methods:The TCMSP database was used to extract the targets of Salvia miltiorrhiza.GeneCards, DisGeNET, Malacard and OMIM databases were used to extract the myopia-related targets.The target intersection was taken, and the intersecting targets were selected to extract the corresponding active ingredients of traditional Chinese medicine (TCM) and construct the pharmacological regulatory network of TCM using Cytoscape.The protein interaction network map for the key target genes was constructed using the String database, and the relevant proteins were selected to download the three-dimensional structures of the active ingredients from the PubChem database, and molecular docking was performed using AutoDockvina software.Twelve 3-week-old guinea pigs were induced with lens-induced myopia (LIM) in the right eye and randomly divided into normal saline group and sodium danshensu group, with 6 animals in each group.During the maintenance of LIM, periocular injection of 1 ml normal saline or sodium danshensu was performed daily.The contralateral eye was used as a negative control.On days 0, 14, and 28 of the experiment, the axial length of both eyes was measured by A-scan ultrasonography, and the refractive status was assessed with a streak retinoscope.To avoid individual differences, relative spherical equivalent (treated eye-contralateral eye) and relative axial length (treated eye-contralateral eye) were compared.On day 28, the relative expression levels of hypoxia-inducible factor-1α (HIF-1α) and transforming growth factor-β1 (TGF-β1) proteins were determined by Western blot.The feeding and use of laboratory animals followed the 3R principle, and the research program was approved by the Ethics Committee of Experimental Animal Center of Zhengzhou University (No.ZZU-LAC 202320405[02]). Results:Sixteen intersecting key targets were screened for myopia and TCM components derived from Salvia divinorum.A TCM network pharmacology map and protein interaction map were constructed with Salvia divinorum as a drug candidate, and the corresponding proteins of target genes, such as MMP2, TGFB1, and MMP9 were screened to perform molecular docking with the active ingredients, such as lignocellulosic acid, danshensu, tanshinone ⅡA, and so on.After 14 days of induction, the relative spherical equivalent and relative axial length were (-4.67±1.03)D and (0.67±0.26)mm in sodium danshensu group, and (-6.30±1.22)D and (1.08±0.34)mm normal saline group, indicating slower myopia progression and axial elongation in sodium danshensu group, and the differences were statistically significant ( t=2.412, P=0.039; t=2.750, P=0.049). The relative expression levels of HIF-1α protein were 0.20±0.01, 1.29±0.05 and 0.63±0.02, and the relative expression levels of TGF-β1 protein were 0.93±0.05, 0.25±0.01 and 0.74±0.05 in the negative control, normal saline and sodium danshensu groups, respectively.The expression of HIF-1α protein was higher in sodium danshensu group than in negative control group but lower than in the normal saline group, and the expression of TGF-β1 protein was lower in sodium danshensu group than in negative control group but higher than in the normal saline group, showing statistically significant differences (all at P<0.05). Conclusions:Natural compounds extracted from Salvia divinorum extracts may serve as potential drug candidates to combat scleral hypoxia and improve scleral extracellular matrix remodeling.
