ObjectiveTo investigate the features of the cortisol ( COR),thyroid hormone and autonomic function of anxiety disorder,and to observe the relationships between clinical subtypes,insomnia,gender factors and the neuroendocrine and autonomic function.Methods60 anxiety disorder patients and 60 healthy controls were randomly selected from a three-grade class A hospital over the same period.Blood at 8:00am to test the plasma COR,T3,T4,TSH level and examined the heart rate variability (HRV) on the same day,the anxiety disorder patients also finish the self-rating anxiety scale (SAS).ResultsThe plasma COR,TSH level and LF/HF index were significantly higher( (531.58 ± 218.59 ) nmol/L,P＜ 0.0l ; (3.50 ± 1.35 ) MIU/L,P＜ 0.05 ;3.87 ± 3.37,P＜0.0l ),while the SDNN,LF,HF index were significantly lower in anxiety disorder than that in the control group (27.34±13.13,P＜0.01;338.72 ±396.34,P＜0.01;135.77 ±149.95,P＜0.01).The plasma COR,TSH level and LF/HF index were significantly higher(P ＜ 0.05,P＜0.01,P＜0.01 ),while the SDNN and HF index were significantly lower in panic disorder than that in the generalized anxiety disorder (P ＜ 0.01 ).The plasma COR,TSH level and LF/HF index were significantly higher,while the SDNN,LF,HF index were significantly lower in panic disorder than that in the control group (P＜0.01 ).The plasma COR was significantly higher,while the SDNN and HF index were significantly lower in generalized anxiety disorder than that of the control group (P＜0.01 ).The plasma COR level and LF/HF index were significantly higher (P＜0.01,P＜0.05),while the SDNN,LF,HF index were significantly lower in anxiety disorder with or without insomnia than that in the control group (P＜ 0.01 ).The plasma TSH level was significantly higher in anxiety disorder with insomnia than that in the control group (P＜ 0.05 ).There were no significant difference of the neuroendocrine and autonomic function between anxiety disorder with or without insomnia (P ＞ 0.05 ).The plasma COR,TSH level were significantly higher,while the SDNN,LF,HF index were significantly lower in the female group than that in the male group (P＜0.01).The total SAS scores were significantly positively correhted with plasma COR levels,and was significantly negatively correlated with SDNN,HF index in the anxiety group.ConclusionThere are neuroendocrine and autonomic nervous system dysfunctions in anxiety disorder,and these dysfunctions are related with clinical subtypes,insomnia,and gender.

This study tested the effects of the gastrointestinal pulse train electrical stimulation with different parameters and at different locations on the neuronal activities of the lateral hypothalamus area (LHA) in obese rats in order to find the optimal stimulation parameter and location. Eight gastric electrical stimulations (GES) with different parameters were performed and the neuronal activities of gastric-distension responsive (GD-R) neurons in LHA were observed. The effects of stimulations with 8 parameters were compared to find the optimal parameter. Then the optimal parameter was used to perform electrical stimulation at duodenum and ileum, and the effects of the duodenal and ileac stimulation on the GD-R neurons in LHA were compared with the gastric stimulation of optimal parameter. The results showed that GES with the lowest energy parameter (0.3 ms, 3 mA, 20 Hz, 2 s on, 3 s off) activated the least neurons. The effects of GES with other parameters whose pulse width was 0.3 ms were not significantly different from those of the lowest energy parameter. Most gastric stimulations whose pulse width was 3 ms activated more LHA neurons than the smallest energy parameter stimulation, and the effects of those 3 ms gastric stimulations were similar. Accordingly, the lowest energy parameter was recognized as the optimal parameter. The effects of stimulations with the optimal parameter at stomach, duodenum and ileum on the LHA neuronal activities were not different. Collectively, gastrointestinal electrical stimulation (GIES) with relatively large pulse width might have stronger effects to the neuronal activities of GD-R neurons in LHA of obese rats. The effects of the GIES at different locations (stomach, duodenum and ileum) on those neurons are similar, and GES is preferential because of its easy clinical performance and safety.

Objective To compare the therapeutic effect of angiotensin Ⅱ antagonist (Valsartan)and angiotension-converting enzyme inhibitor (Captopril) for the improvement of left ventricular systolic function(LVSF) after acute myocardial infarction (AMI) at anterior wall. Methods A total of 75 patients with initial AMI at anterior wall were enlisted in the study. Patients were divided randomly into three groups: control group (n = 15), Captopril treated (n =30), and Valsartan treated (n =30). At 1 week and 28 weeks post AMI, the LVSF and left ventricular regional ejection fraction (LrEF) were measured by equilibrium radionuclide angiography (ERNA). The t-test was used to compare the dada. Results ( 1 ) At 28 weeks, left ventricular ejection fraction (LVEF) and left ventricular peak ejection rate (LPER) in Valsartan treated group were significantly increased as compared with those of control: ( 59.4 ± 8.6 ) % vs (44.9 ± 8.4)%, t = 3.87, P ＜ 0.01 for LVEF; (3.89 ± 1.01 ) end-diastolic volume (EDV)/s vs (2.84 ±1.05) EDV/s, t= 4.16, P ＜ 0.01 for LPER). The left ventricular time to peak ejection rate (LTPER) in Valsartan treated group was significantly decreased ( ( 116 ± 16 )ms vs ( 137 ±20) ms, t =2.16, P ＜ 0.05 ) as compared with control. (2)Compared with 1-week, 28-week Valsartan treated group had a significant increase inLrEF2, LrEF4, LrEF5, LrEF6: (71.6±18.8)% vs (57.0±11.4)%, t=2.11, P＜0.05;(78.1 ±16.8)% vs (68.9±21.0)%, t =2.06, P＜0.05; (70.5±16.9)% vs (59.9 ±23.4)%, t=1.99, P ＜ 0.05; and (58.1 ± 9.0) % vs (46.0 ± 18.9) %, t = 2.43, P ＜ 0.05, respectively. Conclusions Valsartan and Captopril are effective for the improvement of LVEF after AMI at anterior wall. The effects of the two drugs are similar.

The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Objective To investigate the effect of high frequency (10 Hz),low frequency (1 Hz) and theta burst stimulation (TBS) mode of repetitive transcranial magnetic stimulation (rTMS) on the recovery of motor function in hemiplegic patients following acute ischemic stroke.Methods Seventy-two patients with hemiplegia after acute ischemic stroke were randomly grouped with the random number table.They were treated with low frequency (n=18),high frequency (n=18),and TBS (n=18) rTMS or sham stimulation (control group,n=18),once a day,for 2 weeks.Fugl-Meyer Assessment (FMA) and National Institutes of Health Stroke Scale (NIHSS) were used to evaluate neurological function in all patients before rTMS treatment (on the day before the first treatment) and after treatment (on the day after the last treatment).Results After treatment,the FMA and NIHSS scores in the 4 groups were significantly improved compared with before treatment (all P<0.05).After rTMS treatment,the FMA and NIHSS scores were improved significantly in the high frequency group,low frequency group and TBS group compare with the control group (all P<0.05).There were no significant differences among all the treatment groups.Conclusion sHigh frequency,low frequency and TBS rTMS can improve the recovery of motor function in hemiplegic patients following acute ischemic stroke.There were no significant differences among all the treatment modes.

Objective To explore the clinical effect of renal transplant from donation after citizen's death (DCD) donors with acute kidney injury (AKI).Methods This was an observational retrospective study of 622 patients who underwent renal transplantation from 312 DCD donors' kidneys at the First Affiliated Hospital of Xi'an Jiaotong University from December 2011 to December 2016.The transplant patients were divided into AKI group and non-AKI group according to the Acute Kidney Injury Network (AKIN) criteria based on initial and terminal creatinine values.We evaluated and compared transplant outcomes of these two groups.Results There were 131 donors with AKI,and the incidence of AKI was 42.0 ％.AKI group and non-AKI group recipients respectively had DGF in 20.2％ and 7.2％ of cases (P＜0.01),153.6 ± 56.2 and 119.3 ± 40.7 μmol/L of serum creatinine (SCr) levels at 1st month (P＜0.01),and 38.5 ± 14.1 and 57.6 ± 23.4 ml· min-1 (1.73 m2)-1 of eGFR at 1st month (P＜0.01).There was no significant difference in SCr and eGFR between two groups at 1st year after transplantation.Conclusion Most of kidneys from DCD donors with AKI can be considered for transplantation.Renal transplantation of organs from DCD donors with AKI showed greater DGF but good outcomes.

Objective To evaluate the clinical value of adenosine triphosphate (ATP) determination in CD4+ cells in cytomegalovirus pneumonia after renal transplantation.Methods The ATP level of CD4+ T cells was measured by ImmuKnowTM kit.The ATP levels were determined in 187 renal transplant recipients before and 30,60,90,180 days after operation,and at the time of CMV pneumonia and 4 weeks after treatment of CMV pneumonia.The associations between ATP levels and CMV pneumonia were analyzed.Analysis of variance (ANOVA),Pearson-Spearman and relative risks were used for data analysis.Results 17 cases out of 187 renal transplant recipients were diagnosed as CMV pneumonia (9.1％),and the onset of CMV pneumonia started on the (2.8 ±1.2)month after renal transplantation.ATP concentrations in CD4+ T cells were significantly lower after operation than those before operation (P＜0.01).ATP concentrations reached the lowest on the about postoperative day 90 (P＜0.05),then increased gradually.In 17 recipients with CMV pneumonia,the ATP levels before and 30,90 days after operation,at the time of CMV pneumonia and 4th week after treatment of CMV pneumonia were (376 ±182),(283 ± 146),(196 ± 112),(145 ± 102) and (236 ± 117) μg/L respectively.ATP levels at the time of CMV pneumonia were significantly lower than any other time points (P＜0.05).There was close correlation between ATP levels and CMV pneumonia.Conclusion The determination of ATP in CD4+ cells could reflect the status of cell-mediated immunity in renal transplant recipients,and could evaluate the severity and prognosis of CMV pneumonia and guide the clinical treatment.

OBJECTIVETo investigate clinical effects of three-column reconstruction via single posterior approach for the treatment of unstable thoracolumbar fractures accompanied by posterior column injury.

METHODSFrom December 2008 to May 2010,three-column reconstruction via posterior approach was implemented to 21 patients with unstable thoracolumbar fractures accompanied by posterior column injuries. There were 13 males and 8 females, ranging in age from 23 to 54 years old(averaged,35.5 years old). Injured vertebrae: 1 patient had injury in T11, 4 patients had injuries in T12, 8 patients had injuries in L1, 5 patients had injuries in L2, 3 patients had injuries in L3.

Paeoniflorin is the main active ingredient of Chinese herbaceous peony. This study is to investigate the protective effect of paeoniflorin (Pae) on acute brain damage induced by lipopolysaccharide (LPS) in mice. The mice were randomly assigned to the normal control, model control (LPS), as well as groups of paeoniflorin and lipopolysaccharide (Pae + LPS). Then the mice were administered intraperitioneally with normal saline or Pae (10, 30 mg · kg(-1)) once daily for 6 d. One hour after intrapertioneally treatment on the seventh day, each group were injected LPS (5 mg · kg(-1)) to establish the endotoxin lipopolysaccharide inflammation model except the normal group. The mice were sacrificed after 6 h and the brain homogenates were prepared and measured. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2), succinatedehydrogenase (SDH), Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase were dectected by the colorimetric method. The levels of HO-1 and Nrf2 protein in subcellular fractions of brain tissue were detected by Western blot. The results demonstrated that the administration with paeoniflorin reduced the levels of the MDA production; significantly increase the activities of antioxidant enzyme (SOD and GSH-PX). In addition, paeoniflorin could enhance the total antioxidant capacity, decrease the level of H2O2, and increase the activities of SDH, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase. Furthermore, paeoniflorin can increase the expression of HO-1 and activate the nuclear transfer of Nrf2. Taking together, these findings suggest that paeoniflorin alleviate the acute inflammation in mice brain damage induced by LPS, which is related with its antioxidant effect and improvement of energy metabolism.
