Objective To assess the risk factors of intradialytic-hypotension (IDH) and the prognosis of IDH among maintenance hemodialysis (MHD) patients for the prevention and treatment of IDH.Methods 276 MHD patients were enrolled during Jan.2009 to Mar.2009.Intradialytic blood pressure was monitored during a 3-month period.IDH was defined as an event characterized by a sudden drop in systolic BP more than 20 mmHg or in mean artery pressure (MAP) more than 10 mmHgassociated with clinical events and need for interventions.Dialysis-related information was collected.Kaplan-Meier method,log-rank test,logistic regression and Cox regression analyses were performed to examine the association between IDH and survival,using a follow-up through 31 May 2014.Results A total of 276 patients were recruited.The incidence rate of IDH was 40.9％.163 patients with no-IDH (＜ 1/10 hypotensive events/3 months) served as controls.113 patients with IDH (≥ 1/10 hypotensive events/3 months) were identified among all 276 patients.Multivariate logistic regression analysis showed that age,ultrafiltration rate,gender,serum NT-proBNP,serum albumin and aortic rool inside dimension (AoRD) were associated with IDH among MHD patients.During the 5-year follow-up,74 patients died,with a mortality rate 5.2 per 100 person-year.Kaplan-Meier survival curve showed significant difference of overall and CV mortality rates between 2 groups.The multivariate Cox regression model indicated that IDH increased the risk of death (HR=1.572,95％CI 1.077-2.293,P=0.019).So did the rise of LVMI (HR=1.010,95％CI 1.009-1.085,P=0.020).Conclusion Elderly,female,high ultrafiltration rate,high level of serum NT-proBNP,hypoalbuminemia and shorter AoRD are independent risk factors for IDH among MHD patients.LVMI can predict the outcome of MHDpatients.Intradialytic hypotension is an independent risk factor for long-term mortality in MHD patients.

OBJECT: To study sequence polymorphism of mtDNA control region in Chinese Qinghai Tibetan group and Han population. METHODS: Venous blood samples from 69 unrelated Qinghai Tibetans and Han individuals were collected and their mtDNA control region sequences were analyzed. Polymorphism indicators were calculated. The genetic distances based on Fst and Rst among eleven groups from different districts include the Qinghai Tibetan and Han population were elucidated using Nei's method. Phylogenetic tree was constructed. RESULTS: There were 56 polymorphic loci and 59 loci found in the mtDNA control region of Tibetan group and Han population, respectively. It was indicated by the Rst distance that there was a far distance between Qinghai Tibetan and the other populations (P<0.05), and the distance was much closer between Qinghai Han and Xi'an Han, Mongolian, Changsha Han populations (P>0.05). CONCLUSION There is unique genetic polymorphism of mtDNA control region both in Qinghai Tibetan and Han population. These findings may be useful in forensic identification, population genetic and migration studies.

Purpose::Under-foot impact loadings can cause serious lower limb injuries in many activities, such as automobile collisions and underbody explosions to military vehicles. The present study aims to compare the biomechanical responses of the mainstream vehicle occupant dummies with the human body lower limb model and analyze their robustness and applicability for assessing lower limb injury risk in underfoot impact loading environments.Methods::The Hybrid III model, the test device for human occupant restraint (THOR) model, and a hybrid human body model with the human active lower limb model were adopted for under-foot impact analysis regarding different impact velocities and initial lower limb postures.Results::The results show that the 2 dummy models have larger peak tibial axial force and higher sensitivity to the impact velocities and initial postures than the human lower limb model. In particular, the Hybrid III dummy model presented extremely larger peak tibial axial forces than the human lower limb model. In the case of minimal difference in tibial axial force, Hybrid III's tibial axial force (7.5 KN) is still 312.5% that of human active lower limb's (2.4 KN). Even with closer peak tibial axial force values, the biomechanical response curve shapes of the THOR model show significant differences from the human lower limb model.Conclusion::Based on the present results, the Hybrid III dummy cannot be used to evaluate the lower limb injury risk in under-foot loading environments. In contrast, potential improvement in ankle biofidelity and related soft tissues of the THOR dummy can be implemented in the future for better applicability.

Background and objective A solitary pulmonary nodule (SPN) is deifned as a round intraparenchimal lung lesion less than 3 cm in size, not associated with atelectasis or adenopathy. hTe aim of this study is to learn clinical experi-ence of the treatment of SPN with Da Vinci Surgical System. Methods A total of 9 patients with solitary pulmonary nodules (SPN) less than 3 cm in diameter was treated with Da Vinci Surgical System (Intuitive Surgical, California) in thoracic surgery department from General Hospital of Shenyang Militrary Region from November 2011 to March 2014. hTis group of patients included 3 males and 6 females, and the mean age was 51±9.9 yr (range:41-74 yr). Most of the patients were no obvious clini-cal symptoms (7 cases were found by physical examination, others were with cough and expectoration). hTeir median medical history was 12 mo (range:4 d-3 yr). All the lesions of patients were peripheral pulmonary nodules and the mean diameter of those was (1.4±0.6) cm(range:0.8-2.8 cm). Wedge-shaped resection or lobectomy was performed depending on the result of rapid pathology and systemic lymph node dissection was done for malignant leision. We used general anesthesis with double lumens trachea cannula. We set the patients in lateral decubitus position with jackknife. hTe patient cart enter from top of the patient. hTe position of trocars would be set according to the position of lesion. A 12 mm incision was positioned at the 8th intercostal space in the posterior axillary line as vision port, and two 8 mm incisions were positioned at the 5th intercostal space between the anterior axillary line and midclavicular line, and the 8th infrascapular line as robotic instrument ports about 10 cm apart from the vision port. One additional auxiliary small incision for instrument without retracting ribs was set at the 7th in-tercostal space in the middle axillary line. Results hTere were 4 benign leisions and 5 malignancies identiifed. Wedge-shaped resection was performed for 4 patients, lobectomy with systemic lymph node dissection for 3 patients (including 2 right middle lobectomies and 1 letf upper lobectomy) and wedge-shaped resection with systemic lymph node dissection for 2 patients of poor lung function. All of the 9 cases were completed with total robotic procedure without conversion. hTe pathological results included 3 inlfammatory pseudotumors, 1 hamartoma, 5 adenocarcinomas. All of the 29 patients were hospital discharged smoothly. hTe patients were followed up for 0.1-18.5 mo (median 11 mo) without recurrence or metastasis. Conclusion hTe SPN patients should be given active surgical treatments to improve the diagnose rate as well as the cure rate of early non-small cell lung cancer. Since da Vinci Surgical System is a safe and minimally invasive treatment for SPN, it has higher value to the diagnosis and treatment of SPN.

Sepsis brings great burden to the industry of health care and national economy, and antibiotics used in anti-infective treatment will cause the emergence of drug-resistant bacteria, adverse reactions, and reduce the efficacy and quality of life. However, with the deepening of the study of traditional Chinese medicine treatment of sepsis, in reducing the production of drug-resistant bacteria, changing the drug resistance of drug-resistant bacteria, preventing multiple infection, response to inflammatory response and immune damage, treatment of gastrointestinal dysfunction and coagulation disorders, TCM is gradually exerting its advantages. In recent years, with the continuous development of clinical research, the curative effect of traditional Chinese medical way is widely recognized, especially Xuebijing injection. In addition, the clinical research of Chinese medicine, acupuncture, acupoint sticking is more and more. Its play an important role to reduce the mortality of patients with sepsis, reduce inflammatory indexes, blood coagulation index. However, the pathophysiology of sepsis is not clear, the illness progress rapidly and the problem of drug-resistant bacteria resistant, our task is still arduous. Looking forward to the emergence of higher quality research, and looking forward to more individualized and refined treatment programs.

OBJECTIVE: To observe the characteristics of the interstitial fluid (ISF) drainage in the Alzheimer's disease (AD) rats through magnetic resonance imaging (MRI) tracer gadolinium-diethylene triamine pentacetic acid (Gd-DTPA)spread in the brain extracellular space (ECS) and to discuss the role of aquaporin-4 (Aqp4) in the AD. METHODS: Wild type SD rats (300-350 g) and Aqp4 gene knock out (Aqp4^-/-) SD rats (300-350g) were divided into Sham group, AD group, Aqp4^-/--Sham group and Aqp4^-/--AD group. Sham group and Aqp4^-/--Sham group were injected with saline by intraperitoneal each day for 6 weeks, and the AD group and Aqp4^-/--AD group were injected with D-galactose by intraperitoneal each day for 6 weeks. MRI tracer Gd-DTPA (10 mmol/L, 2 μL) was injected into the hippocampus of the rats. MRI scan was performed at the end of 0.5 h, 1.5 h, 1 h, 2 h, and 3 h to observe the dynamic distribution of the Gd-DTPA in the hippocampus and the diffusion rate D^*, clearance rate k' and half-life t_1/2 measured. RESULTS: The diffusion rate D* in Sham group was (2.66±0.36)×10^-6 mm2/s, the diffusion rate D^* in AD group was (2.72±0.62)×10-6 mm²/s, the diffusion rate D^* in Aqp4^-/--Sham group was (2.75±0.47)×10^-6 mm²/s, the diffusion rate D^* in Aqp4^-/--AD group was (2.802±0.55)×10^-6 mm²/s, and there was no statistically significant difference in the four groups (One-Way ANOVA, P>0.05).The clearance rate k' in Sham group was (4.57±0.14)×10^-4/s, the clearance rate k' in AD group was (3.68±0.22)×10^-4/s, the clearance rate k' in Aqp4^-/--Sham group was (3.17±0.16)×10^-4/s, the clearance rate k' in Aqp4^-/--AD group was (2.59±0.19)×10^-4/s, and there was significant difference in the four groups (One-Way ANOVA, P<0.05). The half-life t_1/2 in Sham group was (0.67±0.12) h, the half-life t_1/2 in AD group was (0.88±0.08) h, the half-life t_1/2 in Aqp4^-/--Sham group was (1.12±0.15) h, the half-life t_1/2 in Aqp4^-/--AD group was (1.58±0.11) h, and there was significance difference in the four groups(one-way ANOVA,P<0.05). CONCLUSION The ISF drainage is slow after AD and the loss of Aqp4 in the AD makes the ISF drainage obviously slow down, Aqp4 plays an important role in AD to remove the metabolism of waste out of the brain.

Coronary heart disease （CHD） with atherosclerosis is a common chronic disease worldwide， and anxiety and depression are potential and crucial risk factors for adverse prognosis in CHD. Chaihu Longgu Mulitang （CLMT）， first mentioned in the Shang Han Lun （《伤寒论》）， is a classic prescription for treating Shaoyang diseases combined with disturbance of the mind and spirit， with the effects of harmonizing Shaoyang and calming the mind. Current research on mechanisms has shown that CLMT can play a role in CHD complicated with anxiety and depression through multiple pathways， including regulating related signaling pathways， inhibiting the expression of inflammatory factors， improving oxidative stress damage， modulating neurotransmitter levels， suppressing the hypothalamic-pituitary-adrenal axis， promoting mobilization of mesenchymal stem cells from the bone marrow， and inhibiting platelet activation. Clinical studies have demonstrated that CLMT significantly improves symptoms such as angina and insomnia caused by CHD complicated with anxiety and depression， effectively reduces negative emotions， improves traditional Chinese medicine （TCM） syndrome scores， and decreases levels of inflammatory factors. Furthermore， it has fewer adverse reactions and higher safety than conventional western medicine treatments. This article provides a review of the mechanisms and clinical studies of CLMT in the treatment of CHD complicated with anxiety and depression based on a comprehensive analysis of literature from the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， PubMed， and other databases in the past 15 years， in order to provide references for further research on the use of CLMT in the management of CHD complicated with anxiety and depression.
