Clinical research on the perioperative hemodynamic changes recorded by MostCare/PRAM system in the off-pump coronary artery bypass grafting surgery / 中国胸心血管外科临床杂志

@#Objective    To investigate the perioperative hemodynamic changes of off-pump coronary artery bypass grafting (OPCABG) patients monitored by pulse recorded analysis method (MostCare/PRAM devices) and its relationship with the prognosis. Methods    A total of 89 patients who underwent OPCABG from October 2016 to January 2017 in Beiijng Anzhen Hospital were included, including 53 males and 36 females aged 60.50±8.40 years. The hemodynamic changes were recorded. The patients were divided into two groups (a major adverse cardiovascular events group and a stable group) according to whether major adverse cardiovascular events occurred or not. The difference of hemodynamic changes between the two groups was analysed. Results    The mean percentage increases of stroke volume (SV) in the passive leg raising (PLR) test before opening chest and after chest closure were 23.00%±3.20% and 29.40%±3.70%, respectively. Hemodynamic data were analysed seven times, namely, anaesthesia, opening chest, heparin administration, coronary artery bypass grafting, protamine administration, thoracic closure and after operation. SV was significantly decreased during above periods, while systemic vascular resistance index (SVRI) was significantly increased. Cardiac circle efficiency (CCE) and maximum pressure gradient (dP/dT) were decreased after anaesthesia, and decreased to the lowest value during the procedure of bypass grafting, and then they began to increase gradually after the manipulation of bypass grafting was finished. Stroke volume variation (SVV) and pulse pressure variation (PPV) were slightly decreased during anaesthesia, then increased significantly through the whole surgery. Major adverse cardiovascular events occurred in 9 patients and 4 of them died. The basic mean values of SVRI, SVV and PPV of patients in the major adverse cardiovascular events group before opening chest were significantly higher than those of patients in the stable group. There was no significant difference in the mean values of CCE, dP/dT or SV between the two groups. There was no significant correlation between the prognosis and the mean values of SVRI, SVV, PPV, CCE, dP/dT or SV. Conclusion    The hemodynamic indexes are not stable, thus, it is necessary to monitor the perioperative hemodynamic changes of OPCABG patients timely by MostCare/PRAM device and adjust treatment measures accordingly.

Face holistic processing is modulated by high-motivation intensity:an event-related potential study / 中华行为医学与脑科学杂志

Objective To investigate the influence of high-motivated affect background on the holistic face processing and its neural mechanism.Methods Totally 26 subjects were instructed to perform composite-face process under the priming condition of three emotional pictures (food,neutral and fear).Results (1)Behavioral studies showed a significant interaction between emotion type and face combination(F(2,50) =5.37,P=0.008).Composite-face effect was observed in neutral emotional condition due to the fact that the recognition accuracy of the misaligned face ((90.21 ± 11.20)％) was significantly higher than that of the aligned face((84.83 ± 11.20) ％,t (25) =3.95,P=0.001).However,the composite-face effect disappeared under the condition of high-motivated emotion.That is,there was no significant difference in the recognition accuracy of the misaligned faces ((87.88± 10.28)％) and aligned faces ((85.12± 8.81)％,t(25)=1.93,P=0.065) under the condition of high-motivated negative emotion.Under the condition of high-motivated positive emotion,there was also no significant difference in the recognition accuracy between the misaligned faces ((87.92±11.00)％) and aligned faces((88.33±8.89)％,t(z5)=0.263,P=0.795).(2) According to the results of ERP,P3 components showed significant interaction between emotion type and face combination form(F(2,50) =3.23,P=0.048).Under the neutral emotional condition,the P3 amplitude of aligned faces ((3.46 ± 1.26) μV) was significantly higher than that of misaligned faces ((2.82 ± 1.43)μV,F (1,25)=5.28,P=0.03).In the case of high-motivated negative condition,there was no significant difference in P3amplitude between aligned faces ((3.21 ± 1.16) μV) and misaligned faces ((3.07 ± 1.22) μV,F (1,25) =0.53,P=0.476).The P3 amplitude of aligned faces((3.33±1.20) μV) and misaligned faces((3.42±1.40) μV) were also not significantly different under the condition of high-motivated positive affect (F(1,25)=0.23,P=0.638).Conclusion The study shows a high correlation between face processing and emotional processing.Additionally,the emotional motivation has a stronger influence on face processing.Regardless of the emotional valence,high-motivated intensity affect can cause local attention bias and reduce the holistic processing level of the face,which is mainly manifested in the later cognitive processing stage.

Comparison and reflections on the training of rehabilitation physicians in Taiwan and Mainland China / 中华医学教育探索杂志

Rehabilitation physician training is an important part of the development of rehabilitation medicine.Rehabilitation physician education in Taiwan has a complete and standardized training system,and rehabilitation physician training in mainland China is mainly achieved through standardized residency training.This article compares the differences in training processes for rehabilitation physicians in education in medical colleges and universities,residency training,and specialist training between Taiwan and mainland China.The results show that rehabilitation physician training in Taiwan is rigorous and orderly,with reasonable contents,clear objectives,strong specialty,and standardized assessment,while in mainland China,rehabilitation physicians in mainland China have insufficient training time,and there is a lack of detailed training plan and unified assessment standards.Rehabilitation physician training in mainland China needs to learn from advanced experience,further reform the training process,improve the operability of the overall education program,and perfect the training system of rehabilitation physicians.

The effects of electrically stimulating the right median nerve / 中华物理医学与康复杂志

Objective To explore the effect of right median nerve stimulation ( RMNS) on brain function in healthy subjects . Methods Twenty-eight healthy volunteers were selected as the study′s subjects. RMNS was admin-istered as a task stimulation in a wake-up therapy mode. The subjects were given 30 seconds of stimulation followed by 30 seconds of rest, repeated for 6 times as the block experiment designed, and functional magnetic resonance imaging (fMRI) was performed simultaneously with the task stimulation . The brain activation was analyzed using SPM 12 soft-ware. Results The fMRI showed that RMNS activated primarily the left M1, the premotor cortex (PMC), the bilater-al primary and secondary somatosensory cortexes (S1 and S2), and the left insular lobe. Compared with the resting state, the intensity of BOLD signal in the above activated brain areas changed significantly in RMNS wake-up stimula-tion mode. Conclusion Stimulation of the right median nerve can stimulate the local cerebral cortex and produce a certain wake-up effect by activating the right brain areas related to the motor and sensory functioning of the hand.

Changes in antimicrobial susceptibility of commonly clinically significant isolates before and after the interventions on surgical prophylactic antibiotics (SPAs) in Shanghai

Abstract Surveillances and interventions on antibiotics use have been suggested to improve serious drug-resistance worldwide. Since 2007, our hospital have proposed many measures for regulating surgical prophylactic antibiotics (carbapenems, third gen. cephalosporins, vancomycin, etc.) prescribing practices, like formulary restriction or replacement for surgical prophylactic antibiotics and timely feedback. To assess the impacts on drug-resistance after interventions, we enrolled infected patients in 2006 (pre-intervention period) and 2014 (post-intervention period) in a tertiary hospital in Shanghai. Proportions of targeted pathogens were analyzed: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp. (VRE), imipenem-resistant Escherichia coli (IREC), imipenem-resistant Klebsiella pneumoniae (IRKP), imipenem-resistant Acinetobacter baumannii (IRAB) and imipenem-resistant Pseudomonas aeruginosa (IRPA) isolates. Rates of them were estimated and compared between Surgical Department, ICU and Internal Department during two periods. The total proportions of targeted isolates in Surgical Department (62.44%, 2006; 64.09%, 2014) were more than those in ICU (46.13%, 2006; 50.99%, 2014) and in Internal Department (44.54%, 2006; 51.20%, 2014). Only MRSA has decreased significantly (80.48%, 2006; 55.97%, 2014) (p < 0.0001). The percentages of VRE and IREC in 3 departments were all <15%, and the slightest change were also both observed in Surgical Department (VRE: 0.76%, 2006; 2.03%, 2014) (IREC: 2.69%, 2006; 2.63%, 2014). The interventions on surgical prophylactic antibiotics can be effective for improving resistance; antimicrobial stewardship must be combined with infection control practices.

High-dose heat shock protein gp96 immunization prevents type 1 diabetes via inducing regulatory T cells / 生物工程学报

Type 1 diabetes (T1D), the most prevalent human autoimmune disease, occurs in genetically susceptible individuals. Regulatory T cells (Tregs) are defective in T1D setting. Therefore, efforts to repair or restore Tregs in T1D may prevent or reverse this autoimmune disease. Here, we studied the potential role of rgp96 in preventing T1D, using non-obese diabetic (NOD) mice as an animal model. High-dose rgp96 immunization elicited efficient protection of mice against T1D, as evidenced by stable blood glucose, decreased disease incidence. Significantly increased CD4⁺ CD25⁺ Foxp3⁺ Tregs were observed in immunized mice. In vitro co-culture experiments demonstrated that rgp96 stimulation enhanced Treg proliferation and suppressive function by up-regulation of Foxp3 and IL-10. Our work shows that activation of Tregs by high-dose rgp96 immunization protects against T1D via inducing regulatory T cells and provides preventive and therapeutic potential for the development of an rgp96-based vaccine against T1D.

Relaxant Effect of Daurinoline on Vascular Smooth Muscle of Isolated Rabbit Basilar Artery / 医药导报

Objective To investigate the effect of daurinoline on basilar artery vascular smooth muscle. Methods The tension of isolated basilar artery ring of rabbit was measured. The effects of daurinoline on the basilar artery contracted by methoxamine,5-hydroxytryptamine(5-HT),KCl and Histamine( His)were also examined. Dose-response curves of 5-HT and KCl were observed as well. Results Daurinoline exerted obvious relaxation effect on the basilar artery vascular ring contracted by methoxamine,5-HT,KCl and His in a concentration-dependent manner. IC50 of daurinoline in methoxamine,5-HT,KCl and His-treated rabbits was 8.67×10-5,1.78×10-6,6.79×10-7 and 4.98×10-4 mol·L-1,respectively. The change of concentration-response curves of methoxamine,5-HT,KCl and His showed that daurinoline was a non-competitive antagonist. Conclusion Daurinoline exerts marked relaxation effect on basilar artery of rabbits through non-competitive antagonism. The mechanism of relaxation action may be related to blockage of voltage-dependent or receptor-dependent calcium channels.

Protective effect of total flavonoid C-glycosides from Abrus mollis extract on lipopolysaccharide-induced lipotoxicity in mice / 中国天然药物

Abrus mollis is a widely used traditional Chinese medicine for treating acute and chronic hepatitis, steatosis, and fibrosis. It was found that the total flavonoid C-glycosides from Abrus mollis extract (AME) showed potent antioxidant, anti-inflammatory, and hepatoprotective activities. To further investigate the hepatoprotective effect of AME and its possible mechanisms, lipopolysaccharide (LPS)-induced liver injury models were applied in the current study. The results indicated that AME significantly attenuated LPS-induced lipid accumulation in mouse primary hepatocytes as measured by triglyceride (TG) and total cholesterol (TC) assays and Oil Red O staining. Meanwhile, AME exerted a protective effect on LPS-induced liver injury as shown by decreased liver index, serum aminotransferase levels, and hepatic lipid accumulation. Real-time PCR and immunoblot data suggested that AME reversed the LPS-mediated lipid metabolism gene expression, such as sterol regulatory element-binding protein-1 (SREBP-1), fatty acid synthase (FAS), and acetyl-CoA carboxylase 1 (ACC1). In addition, LPS-induced overexpression of activating transcription factor 4 (ATF4), X-box-binding protein-1 (XBP-1), and C/EBP homologous protein (CHOP) were dramatically reversed by AME. Furthermore, AME also decreased the expression of LPS-enhanced interleukin-6 (IL-6) and cyclooxygenase-2 (COX-2). Here, it is demonstrated for the first time that AME ameliorated LPS-induced hepatic lipid accumulation and that this effect of AME can be attributed to its modulation of hepatic de novo fatty acid synthesis. This study also suggested that the hepatoprotective effect of AME may be related to its down-regulation of unfolded protein response (UPR) activation.

Anti-inflammatory and hepatoprotective effects of total flavonoid C-glycosides from Abrus mollis extracts / 中国天然药物

The aim of this study was to evaluate the anti-inflammatory and hepatoprotective effects of the total flavonoid C-glycosides isolated from Abrus mollis extracts (AME). In the anti-inflammatory tests, xylene-induced ear edema model in mice and carrageenan-induced paw edema model in rats were applied. The hepatoprotective effects of AME were evaluated with various in vivo models of acute and chronic liver injury, including carbon tetrachloride (CCl4)-induced hepatitis in mice, D-galactosamine (D-GalN)-induced hepatitis in rats, as well as CCl4-induced hepatic fibrosis in rats. In the acute inflammation experiment, AME significantly suppressed xylene-induced ear edema and carrageenan-induced paw edema, respectively. In the acute hepatitis tests, AME significantly attenuated the excessive release of ALT and AST induced by CCl4 and D-GalN. In CCl4-induced hepatic fibrosis model, AME alleviated liver injury induced by CCl4 shown by histopathological sections of livers and improved liver function as indicated by decreased liver index, serum ALT, AST, TBIL, and ALP levels and hydroxyproline contents in liver tissues, and increased serum ALB and GLU levels. These results indicated that AME possesses potent anti-inflammatory activity in acute inflammation models and hepatoprotective activity in both acute and chronic liver injury models. In conclusion, AME is a potential anti-inflammatory and hepatoprotective agent and a viable candidate for treating inflammation, hepatitis, and hepatic fibrosis.
