RESUMO
Objective: A longitudinal study was conducted to investigate whether rapid eye movement sleep behavior disorder affect depression in patients with Parkinson's disease through activities of daily living. Methods: A total of 387 Parkinson's disease patients' six-year follow-up data (one follow-up per year) were obtained from the Parkinson's Progression Markers Initiative. To allow causal effects to manifest, this study increased the lag period and divided the data from the six follow-ups into two groups: wave 1 (wave refers to time points), wave 3, and wave 5 as one group, and wave 2, wave 4, and wave6 as the other group. The time interval between two time points in each group was two years. To comprehensively and deeply analyze the dynamic relationships between variables, accurately infer causal relationships, control for individual differences, and detect the stability of these relationships, this study constructed the fixed effects cross-lagged panel model (CLPM), the random effects CLPM (RE-CLPM) model, and the Equating CLPM and Equating RE-CLPM models with applied restriction conditions. Additionally, a reverse path was added to verify the reverse prediction effect. The most suitable data analysis model was selected to explore the relationships between the study variables. Furthermore, the longitudinal mediating effect of daily living activities between rapid eye movement sleep behavior disorder and depression was investigated. Results: In the models, Equating cross-lagged panel model was the best. The lag effect was positive and significant. In wave 1, 3, 5, activities of daily living mediated 11.82% on the path from rapid eye movement sleep behavior disorder to depression; in wave 2, 4, 6, it mediated 13.13%. Therefore, attention should be paid to the treatment of activities of daily living. Conclusion: Longitudinal changes in activities of daily living have indirect effects on the relationship between rapid eye movement sleep behavior disorder and depression, which highlights the importance of changes in activities of daily living ability in Parkinson's disease patients with rapid eye movement sleep behavior disorder.
RESUMO
VPg (virus protein, genome-linked) is a multifunctional protein that plays important roles in viral multiplication in the cytoplasm. However, a number of VPgs encoded by plant viruses target the nucleus and this appears to be biologically significant. These VPgs may therefore be translocated between nuclear and cytoplasmic compartments during virus infection, but such nucleo-cytoplasmic transport has not been demonstrated. We report that VPg encoded by Wheat yellow mosaic virus (WYMV, genus Bymovirus, family Potyviridae) accumulated in both the nucleus and cytoplasm of infected cells, but localized exclusively in the nucleus when expressed alone in plants. Computational analyses predicted the presence of a nuclear localization signal (NLS) and a nuclear export signal (NES) in WYMV VPg. Mutational analyses showed that both the N-terminal and the NLS domains of VPg contribute to the efficiency of nuclear targeting. In vitro and in planta assays indicated that VPg interacts with WYMV coat protein (CP) and proteinase 1 (P1) proteins. Observation of VPg fused to a fluorescent protein and subcellular fractionation experiments showed that VPg was translocated to the cytoplasm when co-expressed with CP, but not with P1. Mutations in the NES domain or treatment with leptomycin B prevented VPg translocation to the cytoplasm when co-expressed with CP. Our results suggest that association with CP facilitates the nuclear export of VPg during WYMV infection.

BACKGROUND:Gastrodin has anti-inflammatory effects and is mainly used in clinical practice for the treatment of ischemic stroke,and its mechanism of action is still unclear. OBJECTIVE:To explore the mechanism of gastrodin intervention on inflammatory injury in ischemic stroke rats. METHODS:Fifty Sprague-Dawley rats were divided into sham-operated group,model group,positive control group,high-dose gastrodin group and low-dose gastrodin group by the randomized numerical method,with 10 rats in each group.Ischemic stroke models were established by the middle cerebral artery occlusion method in all groups of rats except for the sham operation group.Administration in each group started on the 3rd day after surgery,and the rats in the positive control group were intraperitoneally injected with edaravone injection(6 mg/kg),the rats in the high-and low-dose gastrodin groups were intraperitoneally injected with 50 and 10 mg/kg gastrodin injection respectively,and the rats in the sham-operated and model groups were intraperitoneally injected with the equal volume of physiological saline.After 14 days of continuous treatment in each group,the pathological changes in rat brain tissue were observed,and the positive expression of NLRP3 inflammasome and the expression of inflammatory response-related proteins and their mRNAs were detected. RESULTS AND CONCLUSION:Compared with the sham-operated group,the volume of cerebral infarction became larger in the model group;the structure of brain tissue was loose,irregular cavities could be observed,and the number of neurons was reduced and irregularly arranged;the positive expression of NLRP3 inflammasome increased(P<0.01);and the protein and mRNA expression levels of Toll-like receptor 4,myeloid differentiation factor 88,apoptosis-associated speck-like protein containing a caspase-recruitment domain,Caspase-1,and interleukin-1β increased(P<0.01).Compared with the model group,the volume of cerebral infarction became smaller in the high-and low-dose gastrodin groups;the neurons were regularly arranged,increased in number,and uniformly distributed;the positive expression of NLRP3 inflammasome was decreased(P<0.05);the protein and mRNA expression levels of Toll-like receptor 4,myeloid differentiation factor 88,apoptosis-associated speck-like protein containing a caspase-recruitment domain,Caspase-1,and interleukin-1β were decreased in the high-dose gastrodin group(P<0.01);Toll-like receptor 4 protein expression showed no significant changes in the low-dose gastrodin group,and the protein and mRNA expression of the other inflammatory response-associated factors decreased(P<0.05,P<0.01).To conclude,gastrodin attenuates inflammatory injury in ischemic stroke rats,and its mechanism of action may be related to the inhibition of inflammatory response-associate factor expression.
RESUMO
Objective To analyze the correlations of the expressions of miR-4500 and nerve growth factor(NGF)in breast cancer patients with preoperative magnetic resonance(MR)signs.Methods A total of 105 patients with breast cancer admitted to our hospital were selected,the mRNA expression levels of miR-4500 and NGF in breast cancer tissues and adjacent tissues of patients were detected by qRT-PCR,and the positive expression rates of NGF in breast cancer tissues and adjacent tissues were determined by immunohistochemistry method.The correlations of the expressions of miR-4500 and NGF in breast cancer tissues with clinicopathological features and MR signs of patients were analyzed.The targeting relationship between miR-4500 and NGF was predicted by the bioinformatics website,and the correla-tion between the expressions of the two was analyzed.Results Compared with the adjacent tissues,the expression level of miR-4500 in breast cancer tissue decreased(P<0.05),while the level of NGF mRNA and the positive expression rate of NGF increased(P<0.05).There was no significant difference in age,pathological type,tumor classification,parenchymal background,apparent diffusion coefficient or enhancement curve among different expressions of miR-4500 and NGF(P>0.05).The histological grade,lymph node metastasis,tumor diameter,tumor morphology,ring-like enhancement,and peritu-moral brain edema were related to the expressions of miR-4500 and NGF(P<0.05).The bioinformatics website prediction showed that miR-4500 and NGF had binding sites,and the expressions of miR-4500 and NGF mRNA in breast cancer tissues were negatively correlated(r=-0.576,P<0.05).Conclusion The expression of miR-4500 in breast cancer tissue is low,and the expression of NGF is high,which are correlated with the preoperative MR signs in patients,providing a molecu-lar basis for MR signs.
RESUMO
Objective: To investigate the effects of different types of heart failure on long-term renal prognosis in patients with renal insufficiency and heart failure. Methods: The patients with renal insufficiency [baseline estimated glomerular filtration rate < 60 ml·min-1·(1.73 m2)-1] and heart failure followed-up for more than 2 years and hospitalized in Beijing Anzhen Hospital, Capital Medical University from January 1, 2018 to June 30, 2019 were enrolled in this retrospective cohort study. The patients were divided into three groups based on the baseline left ventricular ejection fraction (LVEF): heart failure with reduced ejection fraction (HFrEF, LVEF < 40%) group, heart failure with mildly reduced ejection fraction (HFmrEF, 40% ≤ LVEF < 50%) group, and heart failure with preserved ejection fraction (HFpEF, LVEF ≥ 50%) group. Clinical data were collected and endpoint events (adverse renal outcome: the composite outcome of all-cause death or worsening renal function) were recorded through the electronic medical record system. Kaplan-Meier survival curve was used to analyze the incidence of endpoint events of different heart failure subgroups. Cox regression model was performed to analyze the risk factors of endpoint events. Results: A total of 228 patients with renal insufficiency complicated with heart failure were included, with age of (68.14±14.21) years old and 138 males (60.5%). There were 85 patients (37.3%) in the HFrEF group, 40 patients (17.5%) in the HFmrEF group, and 103 patients (45.2%) in the HFpEF group. There were statistically significant differences in age, proportion of age > 65 years old, sex distribution, systolic blood pressure, pulmonary artery pressure, serum sodium, serum calcium, hemoglobin, serum cholesterol, low-density lipoprotein cholesterol, serum uric acid, troponin I, hypersensitive C-reactive protein, LVEF, ventricular septal thickness, left ventricular end-diastolic diameter, B-type natriuretic peptide, estimated glomerular filtration rate, and proportions of using beta blockers, using spirolactone, myocardial infarction, hypertension, cardiomyopathy and atrial fibrillation (all P < 0.05). During the median follow-up of 36.0 (28.0, 46.0) months, 73 patients (32.0%) had adverse renal outcomes. The total incidences of adverse renal outcomes were 32.9% (28/85) in the HFrEF group, 35.0% (14/40) in the HFmrEF group, and 30.1% (31/103) in the HFpEF group. Kaplan-Meier survival curve showed that there was no significant difference in the incidence of endpoint events among the three groups (log-rank test χ2=0.17, P=0.680). Multivariate Cox regression analysis showed that HFpEF (HFrEF as reference, HR=2.430, 95% CI 1.055-5.596, P=0.037) was an independent influencing factor of endpoint events. Conclusions: The long-term renal prognosis of patients with renal insufficiency and heart failure is poor. Compared with HFrEF, HFpEF is an independent risk factor of poor long-term renal prognosis in renal insufficiency patients with heart failure.

OBJECTIVE To interpret Teacher Training Syllabus for Clinical Pharmacist Training Program (2023 edition) (hereinafter referred as to the “new syllabus”), and to provide reference and guidance for promoting the implementation of the new syllabus and realizing the quality-improving goal of the reform of the clinical pharmacist teacher training program initiated by China Hospital Association. METHODS From the perspective of the management and based on the position of the designer, the new syllabus was interpreted from four aspects: the background of its compilation and release, the process of its compilation and its characteristics, the key improvements of the program and the points for attention about its subsequent implementation. RESULTS & CONCLUSIONS The development and release of the new syllabus provide a “construction blueprint” for the reform of the clinical pharmacist teacher training program of the China Hospital Association. The whole process of compiling the new syllabus is characterized by four basic features: theory-led, goal-oriented, research-based, and synergistic. Compared with the previous syllabus, in addition to the adjustment of the text structure,the new syllabus presents more complete and clearer competence requirements for clinical teaching competence in terms of training objectives; in terms of training content, it further structures the group of task items, pays attention to the 育。E-mail:zhenjiancun@163.com sequential planning and time arrangement of items, and puts forward both quantitative and qualitative refinement requirements for each specific training task;in terms of training methods, it emphasizes the interaction of lecturing, demonstrating and guiding, and the progression of observation, operation and reflection, with the intention of guiding teacher trainees to “learn how to teach by teaching”. In the subsequent implementation of the new syllabus, it is necessary for the teacher training bases to attach great importance to the guarantee of training conditions and process quality management, and to organize the teacher training team to do a good job in the two training programs of “clinical pharmacist training” and “clinical pharmacist teacher training”. Based on further improving the connection between the two training programs, the teacher training team should continue to explore the scientific model of clinical pharmacist teacher training oriented by clinical teaching competence.
RESUMO
OBJECTIVES@#To study the correlation of the expression of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue with hepatic fat content in rats with intrauterine growth retardation (IUGR).@*METHODS@#Pregnant rats were given a low-protein (10% protein) diet during pregnancy to establish a model of IUGR in neonatal rats. The pregnant rats in the control group were given a normal-protein (21% protein) diet during pregnancy. The neonatal rats were weighed and liver tissue was collected on day 1 and at weeks 3, 8, and 12 after birth, and visceral adipose tissue was collected at weeks 3, 8, and 12 after birth. The 3.0T 1H-magnetic resonance spectroscopy was used to measure hepatic fat content at weeks 3, 8, and 12 after birth. Real-time PCR was used to measure mRNA expression levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. Western blot was used to measure protein levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. A Pearson correlation analysis was performed to investigate the correlation of mRNA and protein expression of Lipin with hepatic fat content.@*RESULTS@#The IUGR group had significantly higher mRNA and protein expression levels of Lipin1 in visceral adipose tissue than the control group at weeks 3, 8, and 12 after birth (P<0.05). Compared with the control group, the IUGR group had significantly lower mRNA and protein expression levels of Lipin2 in liver tissue on day 1 after birth and significantly higher mRNA and protein expression levels of Lipin2 at weeks 1, 3, 8, and 12 after birth (P<0.05). At week 3 after birth, there was no significant difference in hepatic fat content between the IUGR and control groups (P>0.05), while at weeks 8 and 12 after birth, the IUGR group had a significantly higher hepatic fat content than the control group (P<0.05). The protein and mRNA expression levels of Lipin1 were positively correlated with hepatic fat content (r=0.628 and 0.521 respectively; P<0.05), and the protein and mRNA expression levels of Lipin2 were also positively correlated with hepatic fat content (r=0.601 and 0.524 respectively; P<0.05).@*CONCLUSIONS@#Upregulation of the mRNA and protein expression levels of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue can increase hepatic fat content in rats with IUGR and may be associated with obesity in adulthood.

RESUMO
China is a country with a high incidence of gastric cancer, ranking the top three in terms of morbidity and mortality. More than 70% of new patients with gastric cancer have been diagnosed at advanced stage. Traditional chemotherapy drugs have hit the plateau. In recent years, oncolytic virus, which specifically kills tumor cells, has developed rapidly. It is considered to have the characteristics of targeting tumor. A large number of viruses replicate in tumor cells, leading to cell lysis or inducing immune response by releasing virus molecules and cytokines further to fight against tumor. The genetically engineered strains of oncolytic virus have shown effective anti-tumor ability both in vivo and in vitro. Its safety and effectiveness have been proved in clinical practice. So the oncolytic virotherapy is expected to be a new direction and breakthrough point in the treatment of gastric cancer. This paper reviews the anti-tumor mechanism, the research progress of genetically engineered strains in the treatment of gastric cancer and the existing challenges of oncolytic virus.
RESUMO
OBJECTIVE:To provide reference for improving the pharmaceutical care in China. METHODs :By comparing the development history ,training contents and status quo of the standardized training system of resident pharmacists in Beijing and clinical pharmacists in China ,combining with policy guidance of the current development trend of clinical pharmacy ,the regins were discussed to optimize the mode of standardization training for inpatient pharmacists in Beijing. RESULTS & CONCLUSIONS:Standardized training for resident pharmacists in Beijing was a compulsory post-graduate education for pharmacists in Beijing hospitals. Post training of clinical pharmacists mainly focused on post-graduate education ,and the main training content was the practical ability of pharmacists in clinical pharmacy ,could be divided to general clinical pharmacists and specialized clinical pharmacists. The standardized training for resident pharmacists in Beijing consisted of two stages ,the first stage was general skills training ,the second stage was specialized skills training. The training content and rotation department of clinical pharmacy in the first stage were similar to post training of general clinical pharmacists in China ,and the training assessment required was more workload for trainees ,but it was not the key point of completion assessment for standardized training of resident pharmacists. During 2015-2017,154 trainees completed the training in Beijing and participated in the second stage completion examination of the standardized training of the resident pharmacists. At the same time ,43 trainees(27.92%)participated in the training of clinical pharmacists. 228 trainees participated in the training of clinical pharmacists in Beijing during the same period , and showed an increasing trend ;most of them had passed the Beijing standardized training for resident pharmacists. It is suggested that the standardized training of resident pharmacists in Beijing can absorb the advantages of post training of clinical pharmacists. In the first stage of training ,the post training of general clinical pharmacists should be carried out at the same time. The post training of specialized clinical pharmacists can be included in the two-stage training of inpatient pharmacists.
RESUMO
Objective To study the effect of atmospheric particulate exposure on the expression of key molecules of Nrf2 signaling pathway involved in oxidative stress and inflammatory response factors in myocardium of rats fed with high-fat and high-glucose diet. Methods A total of 48 SD male rats were randomly divided into control group (CC group), high-fat and high-glucose diet group (HC group), atmospheric particulates group (CP group) and atmospheric particulates plus high-fat and high-glucose diet group (HP group), with 12 rats in each group.Rats were fed in individual ventilated cages (IVC).The CC and HC groups were placed in IVCs equipped with the atmospheric particulate filter, however, the CP and HP groups without the atmospheric particulate filter to make the air composition similar to the outdoor.A total of 24 rats were sacrificed for acquiring myocardial tissue after 3 and 6 months of exposure.The mRNA expression of Nrf2, HO-1, NQO1, VCAM-1 and MCP-1 were measured using RT-qPCR and the protein expression of VCAM-1, MCP-1 detected using western blot. Results The mRNA expression levels of Nrf2, HO-1, NQO1, VCAM-1 and MCP-1 and the protein expression levels of VCAM-1 and MCP-1 in HC, CP and HP groups were higher than CC group (P < 0.05).The mRNA expression levels of Nrf2, HO-1, NQO1, VCAM-1, MCP-1 and the protein expression levels of VCAM-1, MCP-1 in the HP group were higher than HC and CP groups (P < 0.05).The mRNA expression levels of Nrf2 in CP and HP groups after 6 months of exposure were lower than that at 3 months (P < 0.05). Conclusion The exposure of atmospheric particles, high-fat and high-glucose and their combination diets could cause myocardial tissue inflammatory responses, and activate Nrf2 signaling pathways to protect against myocardial damage.

RESUMO
Objective To explore the application of rotation map of insulin injection site in patients with type 2 diabetes in-sulin intensive therapy.Methods 240 patients with type 2 diabetes hospitalized in the endocrinology department for insulin intensive therapy were enrolled in the study by random sampling method from February to September 2016.The patients were divided into ob-servation group and control group by random digit table, 120 cases in each group. The routine insulin injection method was used to guide the patients in the control group. The patients in the observation group were guided by the rotation map of insulin-injection sites during the hospital stay.In the three months and six months after discharge,the two groups were compared in terms of cutaneous reaction. Result The cutaneous reaction of the insulin injection site in the two groups was compared,showing that the incidences of cutaneous reaction in the observation group were significantly lower than the control group 3 months and 6 months after discharge(P<0.05). Conclusion The rotation map of insulin injection sites can prevent patients from repeatedly injecting insulin and thus reduce the incidence of cutaneous reaction.It is worthy of clinical application.
RESUMO
OBJECTIVE:To provide reference to the construct recycling and disposal system for expired drugs of Chongqing families. METHODS:Questionnaire survey was conducted among 1 683 residents from 6 districts of Chongqing,involving whether or not to reserve and regularly check up the drugs in the home;how to dispose expired drugs;reasons for different disposal behavior;suggestions of drug recycling. Epidata 3.1 software was used for data entry and statistical analysis,and corresponding measures and suggestions were put forward. RESULTS:A total of 1 579 effective questionnaires were collected with effective recovery rate of 93.82%. 1 322 residents(83.72%)had the habit of storing drug;1 213 residents(91.75%)disposed expired drugs at random;109 interviewees had participated in expired drug recycling. Inquiries survey showed that 75 residents (68.81%)were not satisfied with the current way of expired drug recycling;90 residents(82.57%)suggested increasing recycling points;101 residents(92.66%)suggested setting recycling points near;93 residents(85.33%)suggested recovering expired drug to the doorstep;97 residents(88.99%)expected compensable drug recovery;1 062 residents who disposed expired drugs with the garbage had strong willingness to participate in drug recovery,and accepted different recycling methods well. CONCLUSIONS:Many residents have the habit of storing drugs,but they lack the consciousness of actively checking up the drugs. The residents deal with the expired drugs in the family casually,and lack the professional knowledge of expired drugs and environmental awareness. The residents who have been involved in recycling are not satisfied with the existing methods of recycling,and they lack of enthusiasm and initiative. The residents support professional expired drug recycling,but the actual behavior is affected by many factors. It is suggested to improve the relevant laws and regulations for the recycling and professional disposal of the expired drugs as soon as possible,construct government-leading,enterprise-participating and multi-lateral cooperative professional family expired drug recycling and disposal system.
RESUMO
Objective To study the incidence and risk factors ofdefecatory dysfunction in acute minorischemic strokepatientsandexplore the influence of the risk factors onprognosis.Methods Clinical data of 274 patients with acute minor ischemic strokewere reviewed and analyzed retrospectively.According to the presence of poststroke defecatorydysfunction,they were divided into defecatory dysfunction group and non-defecatory dysfunction group.The factors associated withdefecatory dysfunctionwere analyzed by univariate analysis and multivariatelogisticanalysis respectively,followed by investigating their effects on the prognosis.Results 74 patients of them with acute minor ischemic stroke had defecatory dysfunction.The univariate analysis indicated that4 factors including baseline NIHSS scorewere the risk factors.Multivariate logistic analysis showed that female,age,diabetes mellitus and baseline NIHSS score were independent risk factors for defecatory dysfunction.The scores of modified Rankin Scale (mRS) after 3 months in minor stroke patients with defecatory dysfunction wassignificantly higher(P < 0.05).Baseline NIHSS score was a predictive factor for the prognosis of post-stroke defecatorydysfunctionpatients.Conclusions Defecatory dysfunction in acute minor stroke patients may increase the risk of poor prognosis.The female,elderlypatients as well those with diabetes mellitus and serious neurologicalfunction deficits are more likely to suffer post-stroke defecatory dysfunction.

RESUMO
BACKGROUND:Absorbable bio-glass injection composed by bio-glass and calcium phosphate bone cement can be tightly combined with bone tissue by a strong chemical bond to improve the stability of the bone-implant interface. OBJECTIVE:To investigate the effect of absorbable bio-glass injection to support the vertebral body of osteoporosis mice and its mechanism of osteogenic induction. METHODS:Osteoporosis models were prepared in 30 female Sprague-Dawley rats undergoing bilateral ovariectomy. After modeling, model rats were randomly divided into three groups, and given polymethylmethacrylate, injectable calcium phosphate bone cement and absorbable bio-glass injection into L3-5 vertebral bone defects, respectively. L3-5 segments were removed at 12 weeks after implantation to detect the biomechanical and degradation properties, levels of calcium and phosphate, alkaline phosphatase activity, bone mineral density, levels of bone morphogenetic protein 2 and transforming growth factor β, as wel as histological observation. RESULTS AND CONCLUSION: In the absorbable bio-glass injection group, the degradation properties, compressive strength, surface hydroxyapatite deposition amount and bone mineral density were significantly higher than those in the other two groups(P< 0.05); trabecular bone relative volume, thickness and number were significant higher than those in the other two groups (P < 0.05); serum levels of calcium, alkaline phosphatase, bone morphogenetic protein 2 and transforming growth factor β were significantly higher than those in the other two groups(P < 0.05); but the level of serum phosphate was lower than that in the other two groups(P < 0.05). These results show that the absorbable bio-glass injection can enhance the support for the osteoporotic vertebral body and induce osteogenesis, probably by increasing bone morphogenetic protein 2 and transforming growth factor β levels.

Objective To investigate the effect of different dose of dexmedetomidine for pre-venting the visceral traction reaction during caesarean section under spinal anesthesia.Methods Two hundred ASA physical status Ⅰ-Ⅱ patients,full-term primiparas scheduled for elective cesarean sec-tion were enrolled in this randomized,placebo-controlled study.Patients were randomly allocated to receive dexmedetomidine in four groups:group C (0.9% normal saline),group D1(dexmedetomidine 0.6 μg/kg),group D2(dexmedetomidine 0.8 μg/kg),group D3 (dexmedetomidine 1.0 μg/kg),50 cases in each group.Two minutes after cutting umbilical,groups D1,D2,D3 received an intravenous infusion single-dose of 0.6,0.8,1.0 μg/kg dexmedetomidine respectively for 10 minutes.Group C was injected the same dose of saline.Maternal blood pressure (BP),heart rate (HR),Ramsay scores,visceral traction reaction conditions were recorded at three points:before iv (T0 ),10 min af-ter iv (T1 )and abdominal exploration (T2 ).Results As for the inhibition of visceral traction pain, groups D2 and D3 were obviously better than groups D1 and C,and there was no statistically signifi-cant difference between groups D2 and D3 at T2 (P <0.05 ).The effects of slowing down heart rate and increasing blood pressure were weaker in group D2 than that in group D3 at T2 .Ramsay scores were higher in groups D2 and D3 than in groups D1 and C (P <0.05),and there was no significant difference between groups D2 and D3 at T2 .Conclusion Administration of dexmedetomidine 0.8 μg/kg could alleviate the visceral traction reaction and had little effect on maternal hemodynamics.
