Objective To investigate the appropriate compatibility of appropriate compatibility of sevoflurane and propofol for patients with mild cognitive impairment (MCI) undergoing posterior lumbar interbody fusion in order to protect their cognitive function.Methods Eighty patients, 41 males, 39 females, aged 65-75 years, BMI 17-26 kg/m2, ASA physical status Ⅰ or Ⅱ, scheduled to undergo elective posterior lumbar interbody fusion, were to be scored according to Montreal cognitive assessment (MoCA), mini mental state examination (MMSE), dementia scale (CDR) and daily living ability scale (ADL) to identify patients with MCI before the surgery.They were randomly assigned to 4 groups (n=20 each) using a random number table: TCI propofol 2.0-2.5 μg/ml group (group P), TCI propofol 1.2 μg/ml+sevoflurane 0.6 MAC group (group PS1), TCI propofol 0.6 μg/ml+sevoflurane 0.9 MAC group (group PS2), 1.0-1.5 MAC sevoflurane group (group S).MoCA and MMSE were used to evaluate the cognitive function of patients 1 d before the operation (T0), after patients become wide-awake (T1), 3 d and 7 d after operation (T2 and T3).Apolipoprotein J (ApoJ) concentration related to cognitive function in blood samples, which were drawn at T0-T3 would be measured with ELISA method.Results Compared with T0, the scores of MMSE and MoCA in four groups decreased significantly (P＜0.05) at T1, the scores of MMSE and MoCA in group S decreased significantly (P＜0.05) at T2;compared with T1, the score of MMSE in the four groups increased significantly at T2, T3 (P＜0.05).The scores of MMSE at T1, T3 in group S decreased significantly compared with groups P, PS1 and PS2 (P＜0.05).The scores of MoCA at T2, T3 in group S decreased significantly compared with groups P, PS1 and PS2 (P＜0.05).Compared with T0, the concentration of plasma ApoJ in the four groups increased significantly at T1 (P＜0.05).Compared with T1, the concentration of plasma ApoJ in the four groups decreased significantly at T2 and T3 (P＜0.05).Compared with group PS1, the concentration of plasma ApoJ at T1, T3 increased significantly in groups S and group PS2 (P＜0.05).Conclusion TCI propofol 1.2 μg/ml combined with 0.6 MAC sevoflurane group is the appropriate compatibility of sevoflurane and propofol for patients with MCI undergoing posterior lumbar interbody fusion,because it has less negative influence on cognitive function and lower concentration of plasma ApoJ.

This study is to observe the effect of salvianolic acid B (Sal B) on neural cells damage and neurogenesis in sub-granular zone (SGZ) and sub-ventricular zone (SVZ) after brain ischemia-reperfusion (I/R) in rats. A modified middle cerebral artery occlusion (MCAO) model of focal cerebral ischemia-reperfusion was used. The rats were divided into four groups: sham control group, ischemia-reperfusion group, Sal B 1 and 10 mg x kg(-1) groups. Sal B was consecutively administrated once a day by ip injection after MCAO. The neurogenesis in SGZ and SVZ was investigated by BrdU method 7 days after MCAO. The Nissl staining for neurons in the hippocampal CA1 and cerebral cortex was performed 14 days after MCAO. A beam-walking test was used to monitor the motor function recovery. We found that brain ischemia resulted in an increase of BrdU positive cells both in ipsilateral SGZ and SVZ at 7th day after MCAO. Sal B (10 mg x kg(-1)) significantly increased further the number of BrdU positive cells both in SGZ and SVZ (P < 0.01). Ipsilateral hippocampal neuron damage occurred and CA1 almost lost 14 days after MCAO. Sal B (10 mg x kg(-1)) obviously attenuated the neuron damage and increased the number of neuron both in ipsilateral CA1 and cerebral cortex (P < 0.01). We also observed an obvious improvement of motor function recovery when Sal B (10 mg x kg(-1)) administrated. From the results above we concluded that Sal B stimulated neurogenesis process both in SGZ and SVZ after brain ischemia, and also alleviated neural cells loss and improved motor function recovery after brain ischemia in rats.

Objective To study the diagnostic value of NBI combined with magnification endoscopy using VS classification standard for early gastric carcinoma lesions.Methods A total of 100 patients with suspected early gastric cancer whose gastric mucosa showed roughness,erosion,abnormal colour or ulcer were collected from January 2013 to June 2014.The lesions were observed under white light endoscopy and then underwent biopsy.Observation and biopsy were conducted in the same location by NBI-ME with self contrast method 2 weeks later.Patients in group A underwent NBI-ME,then were diagnosed by VS classifi-cation standard.Patients in group B were diagnosed with white light endoscopy.The sensitivity,specificity, positive predictive value,negative predictive value and accuracy between group A and group B were com-pared.Results The sensitivity,specificity,positive predictive value,negative predictive value and accura-cy of white light endoscopy in the diagnosis of early gastric carcinoma lesions were 76.19% (16 /21 ), 45.57%(36 /79),27.12%(16 /59),87.80%(36 /41)and 52.00%(52 /100),respectively;while the these variables of NBI-ME for early gastric carcinoma lesions were 95.24%(20 /21),97.47%(77 /79), 90.91%(20 /22),98.72%(77 /78)and 97.00%(97 /100),respectively.The accuracy of NBI-ME for early gastric carcinoma lesions was significantly higher than that of white light endoscopy(χ2 =53.30,P <0.01).Conclusion NBI-ME is convenient and effective in the diagnosis of early gastric carcinoma lesions with high consistency of pathology and good clinical application value.

OBJECTIVE: To investigate the killing effects of VP(3) on nasopharyngeal carcinoma cell line CNE-2. METHODS: Plasmid expression vector pcDNA3.1(-) CMV.VP(3)-His was constructed and identified by Kpn I/EcoR I endonuclease analysis, and then sequenced to verify successful insertion in the sense direction of VP(3) gene. pcDNA3.1(-) CMV.VP(3)-His and pcDNA3.1(-)-His expression plasmid was transiently transfected into nasopharyngeal carcinoma cell line CNE-2 . VP(3) protein expression was detected by Western blotting. MTT assay was used to determine the killing effects of VP(3) gene on nasopharyngeal carcinoma cell line CNE-2. RESULTS: Endonuclease analysis and sequencing confirmed the recombinant plasmid contained the complete VP(3) CDS sequence. Western blotting detected a 14.03 kD protein expression from the transfected cells, which was the expecting band of VP(3) gene. The growth of CNE-2 cells that expressed VP(3) gene was inhibited,while the growth of CNE-2 cells that did not express VP(3) gene was not inhibited. CONCLUSION VP(3) gene can kill nasopharyngeal carcinoma cell CNE-2.

OBJECTIVE: To explore the forensic pathological features of death caused by anaphylactic shock. METHODS: One hundred and forty-two death cases of anaphylactic shock were retrospectively analyzed. The IgE level in the serum of anaphylactic shock cases were statistically compared with that of 62 non-anaphylactic shock cases. RESULTS: Most cases (77.46%) of anaphylactic shock death occurred in the medical institutes, with intravenous drug administration accounting for 53.53% of anaphylactic shock death. β-Lactam antibiotics, glucocorticoid and herbal medications were responsible for a significant proportion of such cases. Although characteristic histopathological changes were absent in vast majority of these anaphylactic shock cases, the differences of IgE levels in the serum between anaphylactic shock group and non-anaphylactic shock group were statistically significant (P<0.05). CONCLUSION Combined information including clinical data, autopsy results, IgE level, and other specific test results should be evaluated together in the forensic pathological diagnosis of anaphylactic shock.

OBJECTIVEAcute intracranial hypertension/cerebral edema (ICH/CE) is an increase in brain volume caused by an absolute increase in cerebral tissue water content. Severe ICH/CE is often associated with a higher mortality and higher neurological consequence rate in intensive care unit. However, little relevant information is available on critical condition of central nervous system in children. The aim of this survey was to study the causes, clinical epidemiology and risk factors of critical illness with ICH/CE in pediatric intensive care unit (PICU).

METHODSCase records of critically ill patients with ICH/CE admitted to PICU in Children's Hospital Affiliated to Shanghai Jiaotong University during the period from January, 1999 to December, 2003 were reviewed for causes, case fatality rate, prognosis and relationship with multiple organ dysfunction syndrome (MODS). Univariate analyses were performed to identify risk factors associated with ICH/CE.

RESULTSDuring the 5 years, 1446 cases with critical illnesses were admitted and ICH/CE developed in 216 patients. The leading causes of ICH/CE were central nervous system infection (27.8%), accidental injuries (22.4%), and sepsis (10.2%). The overall mortality of the patients with ICH/CE was 29.2%. The mortality showed no significant change during the years from 1999 to 2003 (chi(2) = 0.371, P = 0.985). There was no significant difference in mortality of patients with ICH/CE between those with and without neurological diseases (chi(2) = 0.546, P = 0.460). Univariate analyses involving 12 factors indicated the following risk factors: younger age, number of failed organ, lower pediatric critical illness score, underlying diseases, abnormal respiration and change in size of pupil (P < 0.05 or < 0.001). The following factors were not associated with higher risk of death from ICH/CE: sex, organ of primary disease, Glasgow coma score ( 7) on admission, elevated blood pressure and anterior fontanelle change (P > 0.05).

CONCLUSIONSThe mortality of ICH/CE remains high since 1999. Central nervous system infection, accidental injuries, and sepsis were leading causes of ICH/CE in PICU of the hospital. Children who had ICH/CE due to younger age, lower pediatric critical illness score, and complicated with MODS had a higher mortality rate.
