ABSTRACT

Objective@#To investigate the prevalence of anxiety and depression among inpatients with AIDS and its influencing factors, so as to provide the evidence for improving the psychological health among inpatients with AIDS.@*Methods@#The inpatients with AIDS that were hospitalized in an infectious disease hospital in Chengdu City were recruited using the convenient sampling method. The demographic features, depression and anxiety were collected using a self-designed questionnaire, Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale ( SDS ), respectively, and factors affecting the development of depression and anxiety were identified using a multivariable linear regression model among inpatients with AIDS.@*Results@#The 228 AIDS inpatients included 186 men (81.58%) and 42 women ( 18.42% ), and had a mean age of ( 48.04±16.03 ) years. There were 113 inpatients ( 49.56% ) with a CD4+T cell count of ≤200 cells/μL, and the mean SAS and SDS standardized scores were 35.87±8.01 and 42.07±11.08 among AIDS inpatients, which were both significantly greater than in normal populations ( P<0.05 ). The prevalence rates of anxiety, depression, and comorbid anxiety and depression were 5.26%, 16.23% and 4.82% among the participants, respectively. Multivariable linear regression analysis identified unemployment as a risk factor of anxiety ( β'=0.168, P<0.05 ), and CD4+T cell count as a risk factor of anxiety ( β'=-0.151, P<0.05 ) and depression ( β'=-0.238, P<0.05 ) among inpatients with AIDS.@*Conclusions@#Anxiety and depression are prevalent among inpatients with AIDS. Unemployment and a low CD4+T cell count may cause a rise in the risk of developing anxiety and depression among inpatients with AIDS.

ABSTRACT

Patient diagnosis and treatment data are scattered in various clinical systems related to electronic medical records(EMR). The data can be better applied to the emergency prevention and control, medical research and government supervision only through unified integration. The authors analyzed the construction level of the EMR system in medical institutions, and sorted out the problems faced by directly extracting the diagnosis and treatment data of patients through the EMR system, including the lack of patient-centered integration of data, insufficient application depth of the EMR system, insufficient data standardization, lack of data and so on. Public health emergencies posed a severe challenge to the extraction of EMR data.For medical institutions with different information construction levels, the authors gave a feasibility analysis of data extraction by classification and time period, and suggested that medical institutions should fundamentally strengthen the understanding of information, establish data standard system and realize data integration and unified management.

ABSTRACT

Objective:To analyze the immune response in mice after immunization with vaccine of rAd5F35-SIVenvT in combination with rMVA-SIVenvT to evaluate the efficacy of different immunization strategies.Methods:Two recombinant viruses were identified in vitro by PCR and Western blot. The BALB/c mice were immunized with homologous and heterologous immune strategies. The numbers of splenic lymphocytes secreting IFN-γ were measured by ELISPOT assay, meanwhile SIV gp120 antibody titer were measured by ELISA assay. Results:SIVenvT protein was expressed effectively by rAd5F35-SIVenvT and rMVA-SIVenvT in HEK293 cells. The specific immune response reached its peak at 4-week post first immunization, then decreased. SIV Env specific cellular immune response and SIV gp120 specific antibody could be detected at 4-16 weeks post first immunization. The specific cellular response was significant stronger in heterologous immunization group than homologous group at 4 week and 16 week. Furthermore, heterologous immunization induced significant higher titer of SIV gp120 antibody at 4 week than homologous group.Conclusions:Specific immune response induced by rAd5F35-SIVenvT in combination with rMVA-SIVenvT was stronger than homologous vector immunization. The results provided references for further study in nonhuman primates.

ABSTRACT

Objective:To revise the Chinese version of Caregiver Task Inventory (CTI-C) and to evaluate its reliability and validity in family members of mental disorder patients.Methods:Chinese version of Caregiver Task Inventory was revised and adjusted and a survey in a convenience sample of 175 family members of mental disorder patients treated in Jining Psychiatric Hospital was conducted with revised Chinese version of Caregiver Task Inventory (CTI-RC). Two weeks later, another survey 30 of the 175 participants with the CTI-RC were carried out for retesting. After that, item analysis, content validity analysis, exploratory factor analysis, reliability analysis and confirmatory factor analysis for the CTI-RC were implemented.Results:The CTI-RC included five common factors: learning to cope with new role, providing care according to care-receiver′s needs, managing own emotional needs, appraising supportive resources, balancing caregiving needs and own needs, covering 25 items. The reliability analysis showed that Cronbach α of the CTI-RC and its 5 factors of learning to cope with new role, providing care according to care-receiver′s needs, managing own emotional needs, appraising supportive resources, balancing caregiving needs and own needs was 0.850, 0.871, 0.887, 0.817, 0.851, 0.841, respectively. The test-retest reliability of the CTI-RC was 0.878.Conclusions:The revised Chinese version of Caregiver Task Inventory has good reliability and validity, and thus, appear to assess valid dimensions of caring ability in family member of individuals with mental disorders.

ABSTRACT

OBJECTIVE@#To study the genetic variants of a child with Autism Spectrum Disorder (ASD) combined with epilepsy, and explore its possible pathogenic mechanism.@*METHODS@#Clinical data of the child were collected and evaluated, whole-exome sequencing (WES) technology was used to explore the genetic variants sites of the child and his parents and candidate genes were filtered out. Sanger sequencing were performed to verify the variants identified by WES and PolyPhen2 was utilized to predict the function of these variants. qPCR was carry out to determine the expression of the variant gene.@*RESULTS@#The proband carried a compound heterozygous mutation in the SIK3 gene (Chr11 q23.3, NM_025164.6), which contains a missense mutation c.1295A>G (p.N432S) inherited from the father and a deletion [c.2389_2391del(p.797del)] inherited from the mother. Both mutation sites are highly conservative, and PolyPhen2 predicted (c.1295A>G [p.N432S]) to be harmful. Compared to the mother, expression of SIK3in mRNA level in the peripheral blood of the proband and his father were both significantly decreased; compared to normal child, SIK3 expression in the peripheral blood of the proband and two other children with ASD were all decreased significantly too. In addition, studies on mice found that Sik3 gene has a marked higher level of expression in the brain.@*CONCLUSION@#The SIK3 gene variants may probably be associated with ASD. The detailed mechanism needs to be studied further, which may involve lipid metabolism dysfunction in the brain.

ABSTRACT

Objective:To study whether aspirin has inhibitory effect on microglia activation induced by Poly-IC and its mechanism.Methods:Microglia cell line BV2 were cultured in vitro to establish a Poly-IC stimulation-induced microglia cell immune activation model. The experiment groups were divided into control group (no treatment), model group (Poly-IC 10 μg/ml), high dose aspirin group (1 mmol/L aspirin), low dose aspirin group (0.1 mmol/L aspirin), high dose aspirin pretreatment group (Poly-IC 10 μg/ml + 1 mmol/L aspirin) and low dose aspirin pretreatment group (Poly-IC 10 μg/ml + 0.1 mmol/L aspirin). The phagocytosis ability of microglia cells, reactive oxygen species (ROS) and Iba1 protein expression were detected by using immunofluorescence method. The expression of the inflammatory cytokines Il-1β, Il-6, Il-10, TNF-α and cox-2 mRNA in microglia cells were detected by real-time quantitative PCR (RT-qPCR).Results:Compared with the control group, the morphology of microglia cells in model group changed significantly, and the phagocytosis ability and production of reactive oxygen species (ROS) increased. At the meantime, the expression of Iba1 protein was strongly decreased. In the model group, The mRNA expressions of IL-1β(20.55±1.92), IL-6 (63.98±7.83), TNF-α (16.84±3.19), COX-2 (6.78±0.42) were higher than IL-1β(1.01±0.14), IL-6 (0.95±0.17), TNF-α (1.22±0.38), COX-2 (0.87±0.11) in the control group. (Il-1β ( t=26.14), Il-6 ( t=10.22), TNF-α ( t=17.06) and COX-2 ( t=37.07), all P<0.01). In the aspirin pretreatment group, the phagocytic ability of microglia cells was inhibited compared with the model group, and the production of reactive oxygen species (ROS) reduced. The expression of Iba1 protein was also partly recovered. Meanwhile, the effect of the high aspirin dose pretreatment group on pro-inflammatory factors IL-1β(9.95±0.52), IL-6 (39.64±6.89), TNF-α(1.57±0.42), COX-2 (2.47±0.14)were lower than those in the model group significantly.(IL-1β: t=14.18, IL-6: t=3.69, TNF-α: t=16.68, COX-2: t=27.03, all P<0.01). Conclusion:Aspirin has an inhibitory effect on microglial activation induced by Poly-IC, which may be related with inhibiting the expression of inflammatory factors.

ABSTRACT

Objective:To investigate the level and changing trend of microparticles (MPs) in super-elderly infected patients, and explore its early warning effect on infection.Methods:The infected patients ≥ 85 years old admitted to the Second Medical Center of Chinese PLA General Hospital from December 2018 to March 2019 were selected as the observation group, and the healthy volunteers ≥ 85 years old in the same period were selected as the control group. Venous blood samples were collected at the 2nd hour, the 2nd day and the 7th day after fever, and the inflammatory markers such as white blood cell count (WBC), neutrophil percentage (NEUT), C-reactive protein (CRP) and procalcitonin (PCT) were measured. The levels of MPs were determined by flow cytometry. AnnexinⅤlabeled CD11b positive MPs (AnnexinⅤ +/CD11b + MPs) represented leukocyte microparticles (LMPs), and AnnexinⅤlabeled CD66b positive MPs (AnnexinⅤ +/CD66b + MPs) represented neutrophil microparticle (NMPs). The differences of each index at different time points between the two groups were compared, and the predictive value of each index to the infection of elderly patients was analyzed by receiver operating characteristic (ROC) curve. Results:A total of 38 subjects were enrolled, including 28 cases in the observation group and 10 cases in the control group. The levels of LMPs and NMPs in the observation group increased to the peak at the 2nd hour after fever, and were significantly higher than those in the control group [LMPs (cells/μL): 55.0 (28.8, 197.2) vs. 19.0 (13.5, 28.3), NMPs (cells/μL): 226.5 (123.3, 516.5) vs. 26.5 (22.0, 48.8), both P < 0.01]. With the control of the disease, LMPs and NMPs decreased gradually. The NMPs on the 2nd day was significantly lower than that at the 2nd hour of fever [cells/μL: 106.0 (40.0, 309.0) vs. 226.5 (123.3, 516.5), P < 0.05], and the LMPs and NMPs on the 7th day were significantly lower than those on the 2nd day [LMPs (cells/μL): 17.0 (12.5, 43.8) vs. 42.0 (13.0, 117.0), NMPs (cells/μL): 30.0 (15.8, 62.0) vs. 106.0 (40.0, 309.0), both P < 0.05]. There was no significant difference in the levels of LMPs and NMPs between the two groups on the 7th day. Among the inflammatory markers, the NEUT in the observation group was significantly higher than that in the control group at the 2nd hour of fever (0.70±0.09 vs. 0.59±0.04, P < 0.01), but there was no significant difference in WBC, CRP and PCT between the two groups. On the 2nd day, the inflammatory markers in the observation group reached the peak and were significantly higher than those in the control group [WBC (×10 9/L): 9.33±2.44 vs. 6.37±1.28, NEUT: 0.78±0.08 vs. 0.57±0.04, CRP (mg/L): 5.67±2.99 vs. 0.33±0.18, PCT (μg/L): 0.80±0.67 vs. 0.07±0.03, all P < 0.01]. On the 7th day, the inflammatory markers in the observation group decreased significantly, and there was no significant difference between the observation group and the control group. ROC curve analysis showed that the area under ROC curve (AUC) and 95% confidence interval (95% CI) of LMPs and NMPs on the day of fever were higher than those of WBC, NEUT, CRP and PCT [0.888 (0.763-1.000), 0.973 (0.931-1.000) vs. 0.679 (0.346-0.811), 0.829 (0.700-0.958), 0.607 (0.404-0.811), 0.554 (0.358-0.749)]. Conclusion:LMPs and NMPs are significantly increased in the early stage of fever, which can predict the incidence of infection in the super-elderly patients.

ABSTRACT

Objective:To explore the effect of International Classification of Functioning, Disability and Health, Children and Youth Version (ICF-CY) framed oral motor therapy combined with acupoint massage intervention on children with cerebral palsy swallowing disorder.Methods:From September 2018 to September 2019, 80 children with cerebral palsy accompanied by dysphagia who were diagnosed and treated in the Department of Neurological Rehabilitation of our hospital were selected as the study subjects, and were divided into the experimental group (40 cases) and the control group (40 cases) by random number table method. A total of 76 patients completed the study. On the basis of routine swallowing training and oral movement intervention, the experimental group was comprehensively evaluated from the aspects of body function and structure, activity and participation, and environmental factors with ICF-CY theory as the framework, and was given oral and facial acupoint massage for 12 weeks. The control group was given conventional swallowing training and oral exercise intervention for 12 weeks. The modified water swallow test was used to evaluate the effect of improving swallowing disorder in two groups of children after 12 weeks of intervention. The improvement of oral motor function in two groups of children after 4 and 12 weeks of intervention was evaluated by using the Grading Criteria for Evaluation of Oral Motor Function.Results:After 12 weeks of intervention, the total effective rate of swallowing disorder improvement in the experimental group and the control group were 89.47% (34/38) and 63.16% (24/38), respectively, and the difference between the two groups was statistically significant ( χ2 value was 7.28, P<0.05). After 4 and 12 weeks of intervention, the functional scores of oral motors in the experimental group were (67.13±2.35) and (82.08±2.33) points, respectively, which were higher than those of the control group at the same time (56.16±2.57) and (65.63±2.54) points, and the differences were statistically significant ( t values were -3.320, -4.433 P<0.05). After 4 and 12 weeks of intervention, the children's functional scores of oral motors in each group were higher than those in each group before intervention. Compared with the group before intervention, t values of the experimental group were -5.377 and -5.376; t values of the control group were -10.715 and -17.486; compared to the group with 4-week intervention, t value of the experimental group was -12.732; t value of the control group was -13.281, all the differences were statistically significant (P<0.05). The results of repeated measures analysis of variance showed that the time effect, grouping effect, and the interaction between time effect and grouping effect of functional scores of oral motors were statistically significant ( F values were 426.780, 9.084, 26.538, P < 0.05). Conclusions:Oral motor therapy combined with acupoint massage based on ICF-CY framework can effectively promotes the recovery and reconstruction of mouth perception and motor function in children with cerebral palsy, significantly improves the children's dysphagia and their ability to actively participate in feeding.

ABSTRACT

Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.

ABSTRACT

OBJECTIVES@#To establish an electrophysiological model of alcoholic cardiomyopathy by inducing pluripotent stem cells (iPSCs) to differentiate into cardiomyocytes (iPSC-CM) in vitro.@*METHODS@#The human iPSC were expanded in vitro and differentiated into iPSC-CM. The iPSC-CM were divided into a blank control group, an alcoholic experiment group (according to the concentration of alcoholic, the alcoholic experiment was also divided into many subgroups), and a KN93 treatment group. Then the efficiency of iPSC differentiated to iPSC-CM was detected by immunofluorescence, the function of iPSC-CM was detected by cell counting kit-8 (CCK8) assay and lactate dehydrogenase (LDH) activity assay kit. The electrophysiological activity of iPSC-CM was monitored by real time cellular analysis (RTCA), the injury of iPSC-CM caused by alcohol was further verified by the mitochondrial membrane potential fluorescence probe JC-1 staining combined with RTCA analysis.@*RESULTS@#Compared with the blank control group, the different doses (25, 50, 100, 150, 200, 250, 300 mmol/L) of alcohol could significantly inhibit the proliferation of iPSC-CM in a dose-dependent manner (all <0.05). Compared with the blank control group, the activity of iPSC-CM was significantly reduced by 100 mmol/L alcohol, resulting in the increase of LDH release, the decrease of mitochondrial membrane potential, the amplitude and beating rate (all <0.05). Compared with the 100 mg/mL alcoholic experiment group, the KN93 treatment group significantly alleviated the damage of alcohol to iPSC-CM by blocking the necrotic apoptotic pathway, resulting in the decrease of LDH release, the increase of mitochondrial membrane potential, the amplitude and beating rate (all <0.05).@*CONCLUSIONS@#The electrophysiological model of alcoholic cardiomyopathy based on the differentiation of cardiomyocytes are successfully established, which can be used to study the electrophysiological activity and the molecular mechanism for relevant diseases, and it may provide a more reasonable and effective research tool for drug screening and clinical study.

ABSTRACT

Objective The incidence and distribution of positional deformities ( PD) were studied by measuring cranial types of infants aged 0-6 months of 3 hospitals in Chongqing, and the recommended values of local PD were discussed. Methods Data of 3406 infants with 0-6 months head size measurements were col-lected from the Second Affiliated Hospital of Army Military Medical University, Yongchuan Maternal and Child Health Care Hospital and Wanzhou Maternal and Child Health Care Hospital from September 1, 2017 to August 31, 2018, cranial vault asymmetry ( CVA) and cranial index ( CI) were calculated. According to different age groups, observe the distribution of cranial types, and use the current international common diagnostic crite-ria to understand the incidence of cranial abnormalities, and analyze the distribution of percentile values of CVA and CI in infants in Chongqing. Results According to the current international standard diagnosis of PD, the incidence of simple brachycephaly was the highest ( 39. 9%) in the overall cranial abnormalities of infants, followed by brachycephaly with plagiocephaly was the second (36. 1%), simple plagiocephaly was the lowest (6. 9%), and normal cranial type only accounted for 17. 1%. The detection rates of plagiocephaly (36. 9%)and brachycephaly ( 67. 0%) were the lowest in the 0-2 months group, and the highest in the 3-4 months group (47. 3%/83. 3%), and then decreased in the 5-6 months group (46. 6%/80. 2%). Conclusion The basic values of cranial type measurement of full-term infants in chongqing were significantly different from inter-national reports, mainly due to the large CI value. The general international diagnosis standard for positional deformities do not conform to Chinese infants. We suggest that the reference value for positional deformities in this region is as follows: CVA≥0. 4 cm is abnormal, of which 0. 4 cm≤CVA<0. 6 cm for mild plagiocepha-ly, 0. 6 cm≤CVA<1. 0 cm for moderate plagiocephaly, CVA≥1. 0 cm for severe plagiocephaly; 82%≤CI≤91% is abnormal, of which 91%≤CI <94% for mild brachycephaly; 94% ≤CI <99% for moderate brachycephaly; CI≥99% for severe brachycephaly. CI≤82% is scaphocephaly.

ABSTRACT

Objective To propose and validate a reduced volume β-quantification method to measure serum high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Methods The reduced volume β-quantification method involved separation of LDL and HDL by ultracentrifugation and preparation of HDL by chemical precipitation. The sampling and reconstitution of the bottom fractions were performed gravimetrically and sample volume was thus decreased from 5 to 0.8 ml. High performance liquid chromatography was used to determine the cholesterol concentration of bottom fractions and HDL-C in the supernatant. Serum levels of LDL-C depended on a calculation of bottom fractions cholesterol minus HDL-C. Results The total CVs for HDL-C and LDL-C were 0.65% -1.75% and 0.63% -1.11%. The results of the developed method were consistent with the current reference method and well within the allowable bias for Cholesterol Reference Method Laboratory Network surveys. Conclusion A new method for the measurement of HDL-C and LDL-C has been established. This method requires a small amount of serum and is easy to operate, exhibiting a desirable precision and accuracy. It is reliable and can be used as a candidate reference method for HDL-C and LDL-C.

ABSTRACT

Objective To evaluate the effect of propofol and sevoflurane on acute kidney function in infants undergoing pediatric parent liver transplantation.Methods 80 pediatric patients scheduled for pediatric liver transplantation were randomly assigned to receive either continuous infusion of propofol or inhalation of sevoflurane.Serum creatinine (Scr),inflammatory medium and renal biomarkers were measured before surgery (T1),30min after anhepatic phase (T2),3h after ischemia reperfusion (T3),36 h after surgery (T4) to evaluate the effect of anesthetics on the development of postoperative kidney injury.Results Overall,compared Propofol group,the mean arterial pressure changed slightly in sevoflurane group.The inflammatory factors of Scr,IL-18,TNF-α,and levels of NGAL were lower in sevoflurane group while no differences of IL-10 were found between both groups.Conclusions Compared with propofol anesthesia,the degree of renal injury in pediatric living donor liver transplantion under sevoflurane anesthesia is reduced,which may be related to hemodynamic stability and decreased release of inflammatory factors.

ABSTRACT

Objective To compare the effects of sevoflurane-and propofol-based anesthesia on kid-ney injury in pediatric patients undergoing living donor liver transplantation. Methods Eighty pediatric pa-tients of both sexes, aged 5-15 months, weighing 5. 5-10. 0 kg, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, scheduled for elective living donor liver transplantation, were divided into 2 groups ( n=40 each) using a random number table method: sevoflurane-based anesthesia group ( group S) and propofol-based anesthesia ( group P ) . Sevoflurane was inhaled, and the end-tidal concentration was maintained at 1. 0%-3. 0% in group S. Propofol 9-15 mg·kg-1 ·h-1 was intravenously infused in group P. Fentanyl 1-3 μg∕kg was intermittently injected, and cisatracurium 1-2 μg·kg-1·min-1 was intrave-nously infused in two groups. Bispectral index value was maintained at 40-60. Immediately before skin in-cision ( T1 ) , at 30 min of anhepatic phase ( T2 ) , at 3 h of neohepatic phase ( T3 ) , at 24 h after operation ( T4 ) and at day 3 after surgery ( T5 ) , blood samples from the central vein and urine specimens were col-lected for determination of the levels of neutrophil gelatinase-associated lipocalin and cystatin C in serum and urine by enzyme-linked immunosorbent assay. The urine volume, requirement for dopamine and occurrence of hypotension and myocardial ischemia were recorded during surgery. Results Compared with group P, the levels of neutrophil gelatinase-associated lipocalin and cystatin in serum and urine were significantly de-creased at T3-5 ( P<0. 05) , and no significant change was found in the intraoperative urine volume, inci-dence of hypotension and myocardial ischemia, or requirement for dopamine in group S ( P>0. 05) . Con-clusion Compared with propofol-based anesthesia, kidney injury is attenuated in pediatric patients under-going living donor liver transplantation under sevoflurane-based anesthesia.

ABSTRACT

Objective To investigate the effect of dexmedetomidine pretreatment on Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway during myocardial injury induced by liver ischemia-reperfusion (I/R) in rats.Methods Twenty-four healthy adult male SpragueDawley rats,aged 8-10 weeks,weighing 220-250 g,were divided into 3 groups (n=8 each) using a random number table method:sham operation group (group S),liver I/R group (group I/R),and dexmedetomidine pretreatment group (group D).The portal vein,superior and inferior vena cava,subhepatic inferior vena cava and hepatic artery were clamped,and the liver was perfused with 4 ℃ lactated Ringer's solution for 60 min through the portal vein to establish the model of liver cold I/R in anesthetized rats.Dexmedetomidine 100 μg/kg was intraperitoneally injected at 30 min before ischemia in group D.Blood samples were collected at 8 h of reperfusion from the inferior vena cava for determination of serum cardiac troponin Ⅰ (cTnⅠ) and heart-type fatty acid binding protein (H-FABP) concentrations (using the automatic biochemistry analyzer),tumor necrosis factor-alpha (TNF-α) and high-mobility group box 1 protein (HMGB1) concentrations (by enzyme-linked immunosorbent assay).The rats were then sacrificed,andhearts were harvested for examination of histopathological changes (with a light microscope) and for determination of the malondialdehyde (MDA) content (using thiobarbituric acid method) and superoxide dismutase (SOD) activity (by xanthine oxidase method),and expression of phosphorylated STAT1 and STAT3 (p-STAT1,p-STAT3) and phosphorylated JAK2 (p-JAK2) in myocardial tissues (by Western blot).Results Compared with group S,the serum concentrations of cTnI,H-FABP,TNF-α and HMGB1 were significantly increased,the MDA content was increased,the SOD activity was decreased,and the expression of p-JAK2,p-STAT1 and p-STAT3 was up-regulated in I/R and D groups (P<0.05).Compared with group I/R,the serum concentrations of cTnI,H-FABP,TNF-α and HMGB1 were significantly decreased,the MDA content was decreased,the SOD activity was increased,the expression of pJAK2,p-STAT1 and p-STAT3 was down-regulated (P<0.05),and pathological changes of myocardium were significantly attenuated in group D.Conclusion The mechanism by which dexmedetomidine pretreatment mitigates myocardial injury induced by liver cold I/R may be related to inhibiting activation of JAK/STAT signaling pathway in rats.
