Objective To investigate theeffect of ischemic postconditioning (IPO) on ischemia/reperfusion injury via mitochondrial pathway.Methods Male Sprague-Dawley rats were divided into three groups by means of random number table.Rats in IRI group and IPO group received liver transplantation.The portal vein in IRI group was opened immediately after liver implantation to restore the blood supply.The graft rats in IPO group received IPO before the portal vein was completely opened: 60-s ischemia and 60-s reperfusion of the portal vein,repeated 6 times).The rats in the sham-operation group were only subject to dissociation of the liver ligament.Six h after portal vein reperfusion,liver function was tested.The expression of Bcl-2 mRNA and Bax mRNA was detected by using real time-PCR.The protein expression of Cyt-c was detected by using Western blotting.The apoptosis and necrosis of liver tissue and the mitochondrial transmembrane potential were detected by using flow cytomertry.The changes of mitochondrial structure were observed under an electron microscope.Results The liver functions in IRI group and IPO group were significantly worse (P＜0.05),the levels of Bax mRNA were significantly higher (P＜0.05),the levels of Bcl-2 mRNA were significantly lower (P＜0.05),the levels of Cyt-c protein were significantly higher (P＜0.05),the levels of apoptosis and necrosis were significantly higher (P＜0.05),and mitochondrial transmembrane potential (MTP) of liver cells was significantly lower (P＜0.05) than in sham operation group.The changes of all the parameters in IRI group were more significant than in IPO group (P ＜ 0.05).The morphological changes of the liver mitochondria were also significantly aggravated in IRI group as compared with IPO group.Conclusion IPO reduced IRI by inhibiting the mitochondrial signaling pathway in rats undergoing liver transplantation.

The object of this study is to preparate the berberine hydrochloride (BBH) resin compound with taste masking effect. We took the BBH as the model drug and Amberlite IRP69 as the drug carriers, uncovered the curve of solubility of BBH in different cosolvent with a certain range of temperature, and then used it to calculate the parameters during the preparation of the complex such as adding quantity of BBH and the reaction temperature. Afterwards, the characteristic and in vitro release experiments were studied to verify the formation and predict the in vivo release behavior of the complex. The results showed that in the condition of using 60% ethanol as a cosolvent and stirring at 50 ℃ for 1 h, the drug loading and drug availability of the complex are at about 35% and 64%, respectively, and has a better taste-masking effect. In this study, a method was provided for preparing a taste-masking preparation of BBH.

Objective To summarize the clinical experience of surgical treatment for complete atrioventricular septal defect in infants.Methods From December 2013 to June 2004,56 patients aged from 53 days to 12 months with complete atrioventricular septal defect were undergone operations.All patients were diagnosed by 2D-echocardiography,and 18 patients underwent cardiovascular computed angiography (CTA).Rastelli type A had 44 cases,type B 3 cases,and type C 9 cases.The single pericardium patch repair was used for 37 cases,the two-patch repair for 3 cases,and the modified single-patch repair for 16 cases.The time of mechanical ventilation was 26 to 172 hours,and the time of staying at Intensive Care Unit (ICU) was 3 to 19 days.Results There were 5 early deaths caused by severe low cardiac output in 2 cases,renal failure in 2 cases,and severe pulmonary inflammation in 1 case.One late death was due to severe mitral regurgitation with pneumonia and heart failure.The operative mortality was 10.7％.A total of 47 patients was followed-up for 3 months to 5 years after surgery and their heart function was satisfactory.Conclusions The operation should be done between 6 months and 1 year when the diagnosis of complete atrioventricular septal defect (CAVSD) is clear.Its early surgical intervention is satisfactory.The result of surgical treatment for CAVSD depends on both probing intracardiac anatomy carefully and complete correction of associated cardiac abnormalities.

Objective To investigate the effect of dexmedetomidine added to ropivacaine administered locally on prevention of tourniquet?related hypertension in the patients undergoing total knee arthroplast. Methods Ninety patients of both sexes, aged 58-74 yr, weighing 60-78 kg, of American Society of Anesthesiologists physical statusⅠ?Ⅲ, scheduled for elective unilateral total knee arthroplast, were randomly divided into 3 groups ( n=30 each) using a random number table: ropivacaine group ( group R) , dexmedetomidine added to ropivacaine administered locally group ( group D + R ) , and dexmedetomidine administered intravenously + ropivacaine group ( group Div+R ) . Femoral nerve block:0.5% ropivacaine 15 ml was injected in group R; the mixture ( 15 ml) of 0. 5% ropivacaine 20 ml plus dexmedetomidine 60 μg was injected in group D+R; 0.5% ropivacaine 15 ml was injected in group Div+R. Lateral femoral cutaneous nerve block: 0.5% ropivacaine 5 ml was injected in group R; the mixture 5 ml was injected in group D+R; 0.5% ropivacaine 5 ml was injected in group Div+R. General anesthesia was induced after the end of nerve block. In group Div+R, dexmedetomidine was infused as a bolus of 0.5 μg∕kg over 10 min starting from anesthesia induction, followed by an infusion of 0.4 μg·kg-1 ·h-1 until 30 min before the end of surgery. A tourniquet was applied and inflated ( 266-304 mmHg) within 90 min. Before induction of anesthesia ( T0 ) , and at 0, 15, 30, 45, 60, 75 and 90 min after the tourniquet was inflated ( T1?7 ) , mean arterial pressure and heart rate were recorded. The occurrence of hypertension, hypotension, tachycardia and bradycardia was recorded when the tourniquet was inflated. Agitation was assessed and scored after removal of the endotracheal tube. The time for recovery of breathing, emergence time, and time for removal of the endotracheal tube were recorded. Results Compared with group R, the mean arterial pressure and heart rate were significantly decreased at T1?7 in D+R and Div+R groups, the incidence of hypertension and tachycardia was decreased, the incidence of bradycardia was increased, and agitation score was decreased in D+R and Div+R groups ( P<0.05 or 0.01) . There was no significant difference in the parameters mentioned above between group D+R and group Div+R (P>0.05). There was no significant difference in the time for recovery of breathing, emergence time, and time for removal of the endotracheal tube between the three groups ( P>0.05 ) . Conclusion Dexmedetomidine added to ropivacaine administered locally can exert effect on prevention of tourniquet?related hypertension in the patients undergoing total knee arthroplast, and the effect is similar to that of dexmedetomidine administered intravenously.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

Objective To investigate the relationship of albumin levels with the prognosis and severity of illness in elderly sep-sis patients.Methods This was aretrospective study.108 elderly sepsis patients were enrolled from October 2014 to Decem-ber 2015.All patients were divided into survivors group (83 cases)and death group (25 cases)based on the 28-day progno-sis.The differences of clinical data and laboratory were compared between two groups.According to the albumin levels,all patients were divided into three groups,normal albumin group (≥35 g/L,24 cases),and mild hypoproteinemia group (28 g/L≤ALB<35 g/L,52 cases)and severe hypoproteinemia group (<28 g/L,32 cases),respectively.The mortality rate was compared in the groups.Spearman Correlation Coefficient was used to analyze ALB and other factors.Results In all 108 pa-tients,the 28-day mortality rate was 23.1%,and 77.8% of the patients with hypoproteinemia.ALB level [31.7 (28.3~35.7)g/L vs 25.8 (21.7~31.8)g/L,P<0.001]and Hb [128 (110~140)g/L vs 102 (84~132)g/L,P=0.015]in death group were significant lower than that in survival group.Meanwhile,APACHE II scores [20 (18~23)vs 22 (19~24),P=0.015]and SOFA score [6 (5~6)vs 6 (6~7),P<0.001]were higher than that in survival group.The mortality decreased with the increase of ALB level (43.8% vs 21.2% vs 0%,P<0.05).ALB had a negative correlation with APACHEⅡ score (r=-0.190,P=0.049)and coma (r=-0.311,P=0.001),and had a positive correlation with Hb (r=0.449,P<0.001).Conclusion The incidence of hypoproteinemia was high in elderly sepsis patients.ALB level was associated with prognosis and severity of illness among the patients.

Objective The purpose d this investigation was to evaluate the effect d influenza vaccination among medical staff. Methods We chose 134 medical staff who worked in out-patient department and the wards and received influenza vaccination as the inoculation group, 135 medical staff who did not receive influenza vaccination as the non-inoculation group. Investigation with questionnaires was carried out in the two groups 3 months after vaccination. Results The incidence rate of influenza-like disease in the observation group and the control group was 11.2% and 18.5% respectively. The protective rate was 39.46%. The average illness process of influenza-like disease in the observation group and the control group was 1.73 days and 2.96 days. The percent of patients with no medication, one kind of drug medication and two kinds of drag medication was 46.7%, 33.3% and 20.0% in the observation group and 32.0%, 8.0% and 60.0% in the control group. Conclusion Influenza vaccination exerted protective effect for medical staff and other people at high risk of emergency.

Objective To investigate the functional changes of dendritic cells (DC) in elderly patients with sepsis. Method Elderly patients (n = 20), ages 75 to 86 years, treated in the department of internal medicine for cadres and the medical intensive care unit (MICU), were selected to participate in the study. Patients with ma-ligoant tumors, hematological diseases, immune diseases, or a history of receiving drugs known to interfere with immune functions were excluded. Using the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) definition of sepsis, the patients were categorized into four groups: non-sepsis (group A) (n = 5) ; sepsis (group B) (n = 5) ; severe sepsis (group C) (n = 5) ; and septic shock (group D) (n = 5). The peripheral blood mononuclear cells (PBMCs) of each patient were isolated and cultured with human re-combinant granuloceyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in vitro for 10 days. The cells were examined under an inverted microscope, scanning electron microscopy, and flow cytometry. The MTT colorimetric assay was used to observe the abilities of the dendritic cells to stimulale an allogeneic T lym-phocyte response in vitro. Paired t -test was used to compare changes in the surface markers among the different groups, Results The PBMCs in the four groups of patients differentiated into cells with typical dendritic configura-tions after in vitro cuhure with combined cytokines. The CD40, CD80, CD86, and HLA-DR expressions on the cell surfaces increased after culture,with (43.2±12.5)%/(27.3±9.3)%, (31.4 ± 10.1)%/(22.5 ± 8.7)%, (39.3±15.7)%/(21.9±7.7)%, and (75.4±25.6)%/(58.7±16.7)%, respectively. The stimulation index (the abilities of the dendritic cells to stimulale the allogeneic T lymphocyte response in vitro) in the four groups of patients after culture were (23.3±7.9) in group A, (18.9±8.3) in group B,(11.4±5.1) in Group C,and (5.5 ± 3.7) in Group D. Conclusions The immune functions of the dendritic cells of elderly patients with sepsis decrease in a linear manner with the severity of their septic state.
