Objective To establish the corresponding relationship between syndrome differentiation of TCM and clinical test results in chronic hepatitis B patients,and thus to provide objective evidence for TCM treatment. Methods 196 patients with chronic hepatitis B,according to the Chinese medicine dialectical typing results were divided into five groups(liver kidney yin deficiency syndrome type 35 cases,Shire Zhongzu syndrome type 24 cases, Yang deficiency of spleen and kidney syndrome type 26 cases,damp heat resistance type and blood stasis syndrome type 42 cases,liver stagnation and spleen deficiency syndrome type 69 cases).HBV -DNA,hepatitis B,TBIL,ALT, TTT were detected.Results In the HBV -DNA test,the majority of the five groups were positive,the overall compar-ison,the difference was not statistically significant (P =0.937).But in the second liver five,TBIL,ALT and TTT detection,the detection results were reflected in the corresponding relationship between TCMsyndrome differentiation. Such as in TTT detection,liver kidney yin deficiency syndrome type and liver stagnation and spleen deficiency syn-drome type group of patients,most patients with TTT detection results between 7 and 10,two groups sequentially com-pared with the other three groups,the differences were statistically significant (all P =0.000);damp heat resistance type and blood stasis type in the patients group,TTT detection results were generally less than 6,two groups in turn compared with the other three groups,the differences were statistically significant (all P =0.000);Yang deficiency of spleen and kidney in the patients group,TTT detection results were generally more than 10,and compared with the other four groups,the differences were statistically significant (all P =0.000).Conclusion TCMsyndrome differen-tiation of chronic hepatitis B patients has a certain correlation with the clinical test results.

Objective To observe the survival,migration and differentiation of grafted neural stem cells(NSCs)transfected with cardiotrophin-1(CT1)in hippocampus in status epilepticus(SE)rats,and investigate its effect on neuron loss and mossy fiber sprouting(MFS)in hippocampus of SE rats.Methods (1)Lithium-pilocarpine induced SE model rats were divided into 3 groups randomly:CT1-NSCs transplantation group(n=18);NScs transplantation group(n=18)and SE model group(n=18).Another 18 rats served as normal control group.Each group was further divided into 3 time points testing groups(n=6 at each point)corresponding to 1,4 and 8 weeks after transplantation respectively.(2)Under the confocal microscopy,the survival,migration and differentiation of the grafted cells were observed by immunofluorescenee.(3)Morphological changes and neuron loss in the hippocampal CA1 region were examined by Nissl staining.(4)MFS in hippocampal dentate gyrus in rats was obserred by Timm histochemistry.Results(1)At 4 and 8 weeks post-tmusplantation,the numbers of double-labeled NF-200 and EGFP pesitive cells in the CT1-NSCs group were significantly hisher than those in NSCs group.In the former group most of the grafted NSCs migrated away from the needle tract,but in the latter group,grafted ceHs remained at the transplantation site.(2)The numbers of neuron in the hippocampal CA1 region reduced gradually after SE.The numbers of neuron in the CA1 region in CT1-NSCs transplantation rats (68.85±11.49,60.89±12.17 and 51.51±13.34 in 1,4,8 weeks after transplantation respectivelv)were greater than that in NSCs transplantation rats(67.92±10.78,42.56±11.47 and 30.49±10.12).tvalue were 4.650 and 5.334 in 4 and 8 weeks after transplantation(P<0.05).(3)Aberrant MFS in the inner molecular layer of dentate gyrus was observed,and the scores of MFS gradually increased with timelapse.The scores of MFS in CT1-NSCs transplantation rats(0.77±0.04,2.48±0.89 and 2.39±0.82 in 1,4,8 weeks after transplantation respectively)were significant lower than that in NSCs transplantation rats (1.12±0.62,3.17±0.64 and 3.88±0.51,t=6.059,9.511 and 9.728,P<0.05).Conclusions CT1 could promote the survival,migration and differentiation of engrafted NSCs in hippocampud in SE rats.Engrafted NSCs transfected with CT1 have effect on repair of the injured hippocampus,and could inhibit hippocampus MFS in SE rats.

AIM:To set up a glutamate-induced cell damage model in cultured hippocampal neurons, and to determine whether glutamate-induced neuronal apoptosis changes and whether this process is mediated by mitochondrial signal transduction pathways involving the release of cytochrome C. METHODS: Hippocampal neurons, isolated and cultured from new born Wistar rats, were exposed to various concentrations of glutamate. Extent of cell death was assessed by measuring the release of lactate dehydrogenase (LDH) in the culture media. Based on these data, an appropriate concentration of glutamate was selected, and all subsequent experiments were carried out under the concentration. Kinetics of glutamate-induced both apoptotic and necrotic cell death after exposure to glutamate for various times(3-24 h) were determined by flow cytometry and LDH release. The caspase-3 protein levels and cytochrome C release from mitochondria into cytosol in hippocampal neurons were determined by Western blotting. RESULTS: Glutamate treatment induced hippocampal neurons death in dose-dependent and time-dependent manners. A significant increase in LDH release (18.4%) was induced in the cells treated with 50 ?mol/L glutamate, compared to control untreated cells(P

Objective To evaluate the effect of sevoflurane preconditioning on the left ventricular function in patients undergoing coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB).Methods Thirty ASA physical status Ⅱ or Ⅲ patients,aged 42-70 yr,with body height 152-181 cm,weighing 43-78 kg,scheduled for elective CABG under CPB,were randomly divided into 2 groups (n =15 each) using a random number table:control group (group C) and sevoflurane preconditioning group (group SP).Group SP inhaled sevoflurane with the end-tidal concentration corresponding to 1 MAC for 30 min after endotracheal intubation.Before sevoflurane preconditioning (T0) and at 60 min after termination of CPB (T1),mean arterial pressure (MAP),stroke volume index (SVI),pulmonary artery obstruction pressure and the TEE variables including left ventricular ejection fraction (LVEF),peak E wave velocity (E),systolic wave velocity (S),and diastolic wave velocity (D),and low propagation velocity (Vp) were recorded.S/D ratio and E/Vp ratio were calculated.Extubation time and duration of ICU stay were also recorded.Results Compared with the baseline value at T0,HR was significantly increased at T1 (P ＜ 0.05 or 0.01),and no significant change was found in the other parameters of the left ventricle function in the two groups (P ＞ 0.05).There was no significant difference in the parameters of the left ventricle function,extubation time and duration of ICU stay between SP group and C group (P ＞ 0.05).Conclusion Preconditioning with inhalation of sevoflurane with the end-tidal concentration corresponding to 1 MAC before CPB does not produce myocardial protection in terms of the left ventricular function or exerts little effect on the short-term outcomes.

Objective To establish normative data for the fetal cisterna magna septa (CMS) at various gestational age,and to evaluate its clinical significance.Methods A total of consecutive fetal between 14 and 40 gestational week(GW) were included in this prospective study.The length and width of CMS were measured by two-dimensional ultrasonography.Regression analysis was used to study the relationship between the width and length of the fetal cisterna magna septa and gestational age.Twenty-five case of fetuses with the absence of CMS and 12 case of fetuses with the enlargement of CMS were retrospectively analyzed in the past six years in our hospital.Results ①The fetal CMS length and width increased gradually between 14 and 22 GW,then plateaued between 23 GW and 36 GW,and decreased after 37 GW.This ultrasonographic pattern was in agreement with normal development of rhombencephalon.②The absence of CMS in the fetuses were common in Dandy-Walker syndrome,holoprosencephaly,severe hydrocephalus,neural tube defects,rhombencephalon synapsis and Arnold-Chiari malformation.The enlargement of CMS in the fetuses may be shown in physiologic enlargement of posterior fossa.ConclusionsCMS is a potential new marker for normal development of rhombencephalon.The enlargement and absence of CMS are related to various malformations of central neural system,especially in the abnormalities of posterior fossa.

Objective:To investigate the effect of resveratrol ( Res ) on endoplasmic reticulum stress induced by cerebral ischemia/reperfusion(I/R)injury in rats.Methods:The seventy-two male SD rats were divided randomly into three groups(n=20):sham operation group ( group S ) , I/R group and Res-treatment group ( group R ) .Focal cerebral I/R model was induced by electrocoagulation of left middle cerebral artery and occlusion of bilateral common carotid arteries followed by reperfusion after 30 min.The rats in Res group were treated with Res(50 mg/kg)i.p.7 d before the operation,once a day for 7 d.Neurological deficits were assessed at 24 h post-injury,followed by collecting the brain tissues.Cerebral infarct size was detected by TTC staining,and the water content of brain tissue were measured by wet-dry weight method.The expression of GRP78,p-PERK and CHOP proteins were deter-mined by immunohistochemistry and Western blot analysis.Results:Compared with sham group,the neurological deficit score and the brain water content were significantly increased(P<0.05),cerebral infarct size was enlarged(P<0.05),and the expression of GRP78, p-PERK and CHOP were up-regulated in I/R group(P<0.05).At the corresponding time,compared with I/R group,the neurological deficit score and the brain water content were markedly decreased(P<0.05),cerebral infarct size was smaller(P<0.05),the level of GRP78 was notablely increased(P<0.05),while the expression of p-PERK and CHOP were down-regulated in Res group(P<0.05). Conclusion:Resveratrol plays a protection role in ischemia-reperfusion injury, through inhibiting the endoplasmic reticulum stress in rats.

Objective To evaluate the changes in the right ventricular systolic and diastolic function during the early period after cardiopulmonary bypass (CPB) in patients undergoing coronary artery bypass grafting (CABG).Methods Eighteen ASA physical status Ⅱ or Ⅲ patients of both sexes,with coronary heart disease (NYHA Ⅱ or Ⅲ),aged 50-80 yr,weighing 51-96 kg,with left ventricular ejection fraction≥50％,scheduled for elective CABG under CPB,were enrolled in this study.Before splitting of sternum and at 5 min after termination of CPB,the parameters of hemodynamics,cardiac output (CO)and variables of right ventricular function (using transesophageal echocardiography) including tricuspid annular plane systolic excursion (TAPSE),right ventricular fractional area change (RVFAC),tricuspid annular peak velocity during isovolumic contraction (IVV),peak velocity during ejection phases (St),early diastolic peak velocity (Et),late diastolic peak velocity (At),E/Et ratio and Et/At ratio were recorded.Results Compared with the baseline value before splitting of sternum,TAPSE,IVV,St,RVFAC,CO,E,Et and At were significantly increased,and no significant change was found in the parameters of hemodynamics and E/Et and Et/At ratios at 5 min after termination of CPB.Conclusion For the patients undergoing CABG,the right ventricular systolic function is significantly enhanced,and there is no obvious improvement in the right ventricular diastolic function during the early period after CPB.

Objective To evaluate the effect of sevoflurane-based anesthesia on the interventricular synchronization in the patients undergoing coronary artery bypass grafting (CABG) with cardiopuhnonary bypass (CPB).Methods Twenty-four Amnerican Society of Anesthesiologists physical status Ⅱ or Ⅲ patients,aged 52-75 yr,with body mass index of 17-31 kg/m2,with body surface area of 1.7-2.2 m2,of New York Heart Association Ⅱ or Ⅲll,with left ventricular ejection fraction (LVEF) ≥45％,scheduled for elective CABG with CPB,were divided into 2 groups (n=12 each) using a random number table:propofol combined with remifentanil anesthesia group (group C) and sevoflurane combined with propofol and remifentanil anesthesia group (group S).After induction of general anesthesia,the patients were en-dotracheally intubated and mechanically ventilated.Anesthesia was maintained by Ⅳ infusion of propofol,remifentanil and cisatracurium,and the cerebral state index value was maintained at 40-60.In group S,the patients inhaled sevoflurane (the end-tidal concentration was 1.80％ for 50-59 yr and 1.60％ for 60-75 yr) for 60 min starting from 15 min after termination of CPB.After induction of anesthesia and before splitting of sternum,immediately before inhaling sevoflurane and at 30 and 60 min of sevoflurane inhalation,heart rate,cardiac index,LVEF,right ventricular eject fraction,QRS width and interventricular mechanical delay were recorded,and the occurrence of interventricular dyssynchrony was recorded.Results There were no significant differences between group C and group S in the heart rate,cardiac index,LVEF,right ventricular eject fraction,QRS width,interventricular mechanical delay or incidence of interventricular dyssynchrony (P＞0.05).Conclusion Sevoflurane-based anesthesia exerts no marked effect on interventricular synchronization in the patients undergoing CABG with CPB.
