Objective To explore mycocardial protection effect of sevoflurane post-conditioning in off-pump coronary artery bypass grafting (OPCABG) surgery,and the mechanism of mycocardial protection of sevoflurane post-conditioning.Methods Thirty six patients undergoing OPCABG were randomly divided into three groups:at 1.5 MAC (minimum alveolar concentration) for 5 minutes first,with an interruption control group (Cont group),sevoflurane preconditioning group (SPC group),and sevoflurane postconditioning group (SPO group).All patients were administrated by intravenous anesthetic drug,both for induction and maintenance.No special interventions were used in Cont group.However,in SPC group,12 patients inhaled sevoflurane for 10 minutes,then continued for 5 minutes,total 10 minutes before the anastomotic between mammary artery and anterior descending artery.In SPO group,12 patients inhaled sevoflurane at 1.5 MAC for 2 minutes before the anastomosis of last one coronary artery,and continued for 8 minutes.Four time points were focused on including T1 (accomplishment of induction),T2 (1 hour after the coronary revascularization),T3 (6 hour after the coronary revascularization),and T4 (24 hour after the coronary revascularization).Blood samples were drawn from the internal jugular vein for the measurement of the plasma concentrations of TNT-hs (highly sensitive cardiac troponin T),CK-MB (creatine phosphokinase isoenzyme),NT-proBNP (N-Terminal fragment of the prohormone Brain-Type Natri-uretic Peptide),and TNF-α (tumornecrosis factor-α).Results All the patients completed the trials without significant adverse effects.The age,gender,ejection fraction,and operative time among three groups were no statistically significant difference (P ＞ 0.05).Stay time in postoperative ICU and hospital were significantly less than Cont group (P ＜ 0.05).Compared to the pre-operative baseline,all patients'plasma concentrations of TNT-hs,CK-MB,NT-proBNP,and TNF-α were significantly increased at 1 h,6 h,and 24 h after coronary revascularization (P ＜0.05).TNT-hs in Cont group showed a persistent increase,while in other two groups (SPC and SPO),TNT-hs reached the peak concentrations at 6 hours after the coronary revascularization,which were same with CK-MB,TNF-α,and MDA in all groups;NT-proBNP reached the peak at coronary revascularization after 24 h.Compared to Cont group,TNT-hs,CK-MB,and TNF-α in groups SPC and SPO were significantly lower at 6 h,24 h after coronary revascularization; NT-proBNP was significantly lower only at 24 h after coronary revascularization.Conclusions Sevoflurane post-conditioning in OPCABG has identified myocardial protection,which was comparable with sevoflurane preconditioning.

The fetal inlfammatory response syndrome (FIRS) is a subclinical condition characterized by systemic acti-vation of the fetal innate immune system with a large number of pro-inlfammatory cytokines released. FIRS is the fetal coun-terpart of the systemic inlfammatory response syndrome (SIRS) described in adults. Intrauterine infection is the most common reason of FIRS. FIRS has been implicated as a cause of preterm labor, preterm white matter injury, bronchopulmonary dyspla-sia (BPD) and necrotizing enterocolitis (NEC).

Thus, this demands a great quantity of Yi ethnic medicine, but it also leads rapid decline with overuse of the medical resources. Here we discussed a series of problems, and put forward the corresponding stradegies of protection of Yi medicine.

Objective To investigate the protective effects of ulinastatin on myocardial reperfusion injury during cardiopulmonary bypass(CPB) in patients underwent valve replacement. Methods 26 ASA Ⅱ-Ⅲ patients scheduled for valve replacement were randomly divided into control group (group C) and ulinastatin group ( group W), each group containing 13 patients. In group W, the patients received ulinastatin 12000U?kg -1 , half dose of which was given before CPB, and the other half was added into the primary solution. Plasma levels of CK,CK-MB and cTnI were measured before operation(T 1), 20 min after starting CPB(T 2), 30 min after declamping aorta (T 3), and 4h(T 4) and 24h(T 5) after operation. Results The plasma level of CK, CK-MB and cTnI increased significantly at T 3, T 4 and T 5 in the both groups compared with T 1(P

Objective: To evaluate the quality of life of schizophrenic patients spouses living in the community. Methods:One hundred schizophrenic patients spouses and 60 control subjects were adminstered the General Quality of Life Inventory (GQOLI). Results: The schizophrenic patients spouses reported significantly lower score on the quality of life than the controls in the domains of physical health, mental health, social function and economic condition. The characteristics of disease played an important role in the quality of life. Conclusion: The quality of life of schizophrenic patients spouses were poorer than that of control subjects.

Objective To explore the characteristics of occult damage of cerebral white matter in patients with small vessel disease by using diffusion tensor imaging (DTI)technology,and its relationship with cognitive impairment.Methods Twenty-eight patients with CSVD and twenty-three matched volunteers all received T1 WI,T2 WI,DTI examination and montperllier cognitive function scale (MoCA).Then compare the difference between the two groups,and analysis the correlation between ADC and FA value of each re-gion of interested and MoCA score in CSVD group.Results ①FA values on bilateral frontal white matter in CSVD group were lower than control group,and ADC values were higher than control group,the difference was statistically significant (P <0.05 ).There were no significant differences in FA and ADC values on corpus callosum genu and splenium between two groups (P >0.05 );②In CSVD group,the FA value of bilateral frontal lobe white matter were positively correlated with the MoCA score (P <0.05 ),and the ADC value were negatively correlated with the MoCA score (P <0.05 ).there were no significantly correlations between FA and ADC values on corpus callosum genu and splenium and MoCA score (P >0.05 ).Conclusion Bilateral frontal white matter exist fi-ber occult damage in patients with CSVD,and the change of FA and ADC value can reflect the severity of cognitive impairment on a certain degree in patients with CSVD.

Objective Analyzed the cause and time of hypokalemia complication that dexamethasone used for hyperthyroidism preoperative preparation.Methods The study consisted of 161 patients with hyperthyroidism disease,who were used the dexamethasone in his or her preoperative preparation at the First Affiliated Hospital of Zhengzhou University between August 2011 and July 2013.Results In the 161 hyperthyroidism patients,composed of 41 men and 120 women,twenty-seven patients happened hypokalemia and 92.6％ occurred after the first.Twenty-six men patients developed hypokalemia complication when used dexamethasone for hyperthyroidism preoperative preparation,while only 1 woman patient occurred the hypokalemia complication.Among the 11 patients who with a history of thyrotoxic periodic paralysis,10 cases occurred after given dexamethasone hypokalemia,only 1 case has no hypokalemia.Conclusion Dexamethasone and other drug used in hyperthyroidism preoperative preparation,which was rapid,safe and effective,but it can lead to hypokalemia complication,especial in the 24 hours after the first use,should be brought clinical doctors attentions,and give timely diagnosis and treatment.

To explore the mechanism of Notch in hyperoxia-induced preterm rat lung injury, 2-days-old preterm SD rats were randomized into control and hyperoxia group (FiO2 > or = 0.85). On day 1, 7, 14 and 21, 8 rat pups of each time point were used to assess histopathological changes of lung with HE staining and to evaluate the expression of Notch1 and Notch3 with immunohistochemistry. Notch1, Notch3, Aquaprin5 (AQP5) and surfactant protein C (SP-C) mRNA were measured by reverse transcription polymerase chain reaction (RT-PCR). The results showed that the lung injury in the hyperoxia group was characterized by retarded lung alveolization and differentiation of alveolar epithelial type II cells (AEC II). Positive staining of Notch1 in hyperoxia group was weaker than controls at every time point (except for day 7), while positive staining of Notch3 was much stronger (P < 0.05, P < 0.01). Notch1, Notch3 mRNA level showed similar change as protein level. AQP5, SP-C mRNA decreased significantly as compared with that of the controls (P < 0.01). We are led to conclude that hyperoxia results in abnormal expression of Notch, which is likely to contribute to the pathogenesis of lung injury through regulating proliferation and transdifferentiation of alveolar epithelial cells.

Objective To study the risk factors for failure of INSURE strategy in very and extremely low birth weight preterm (V/ELBW) infants.Method From January 2005 to December 2014,clinical data of 149 preterm infants (gestational age less than 32 weeks) admitted to neonatal department of Tongji Hospital who received intubation-surfactant-extubation (INSURE) strategy were collected.These infants were assigned into two groups:INSURE failure group and INSURE success group,according to whether a second dose of surfactant or mechanical ventilation was needed within 72 hours after first pulmonary surfactant treatment.The clinical characteristics and outcomes between the two groups were compared.Chi square and t tests were used to define the differences between groups.Logistic regression analysis was used to identify the independent risk factors for INSURE failure.Result Among the 1 149 patients,148 received INSURE treatment,and 113 cases (76.4％) were successfully treated with the INSURE strategy.The infants in the failure group were statistically lower in birth weight,gestation age,antenatal steroids utilization rate,PaO2 and PaO2/FiO2 than those in the success group,while the age of mother,male/female ratio and PaCO2 were higher in the failure group.Logistic regression analysis showed that male (OR =7.440,95％ CI 1.846 ～29.984),BW ＜ 1 000 g (OR =9.180,95％ CI 1.716 ～49.105),PaCO2 ＞48 mmHg (OR =5.996,95％ CI 2.088 ～ 17.213),PaO2/FiO2 ＜205 (OR =3.010,95％ CI 1.033 ～8.774) were independent risk factors for INSURE failure.Conclusion INSURE strategy failure was associated with gender,birth weight,gestation age,antenatal steroids utilization,PaO2,PaCO2 and PaO2/FiO2 of the first blood gas after birth.BW ＜ 1 000 g,PaCO2 ＞ 48 mmHg and PaO2/FiO2 ＜ 205 of the first blood gas after birth were independent risk factors for INSURE strategy failure.

Objective To construct the plasmid that can produce long,double-stranded RNA and identify nonspecific apoptosis induced by long, double-stranded RNA in human osteosarcoma cells. Methods Plasmid pCI-neo-dsRNA was constructed by two promoters driven DNA sequence based on nontoxic, completely exoteric gene EGFP from the head and the end simultaneously to synthesize sense and antisense RNAs. Human osteosarcoma cells MG63 were transfected with pCI-neo-dsRNA and 48 h later the transfected cells were assessed by Apoptosis Detection System, FCMand MTT method. Results Plasmid pCI-neo-dsRNA was constructed successfully, MTT measurement showed that the absorbance of cells decreased gradually with the increase of plasmid pCI-neo-dsRNA dose(0.05 ?g, 0.10 ?g, 0.15 ?g, 0.20 ?g,0.25 ?g,0.30 ?g). MG3 transfected with pCI-neo-dsEGFP presented a great amount of irregular green fluorescence that indicated cell apoptosis. As the quantity of dsRNA increased, the percent of apoptosis cells also raised. While the dose of pCI-neo-dsEGF was 3.0 ?g, the apoptotic results of pCI-neo-dsEGF in MG3 were similar to that of 5-FU. Conclusion Long, double- stranded RNA could trigger human osteosarcoma cell apoptosis and the further research on using long, double-stranded RNA in osteosarcoma gene therapy can be done based on this theory.
