To explore the effect of propofol on human cardiac AC16 cells under CoCl2-induced hypoxic injury and the possible mechanisms.
Methods: Human AC16 cardiomyocytes were treated with cobalt chloride (CoCl2) to mimic hypoxic condition in cultured cardiomyocytes. The AC16 cells were divided into 3 groups: a control group, a CoCl2 hypoxia group (CoCl2 group), and a propofol+CoCl2 group (propofol+ CoCl2 group). The cell viability was assessed by cell counting kit-8 (CCK-8). Cell apoptosis ratio (AR) and the mitochondrial membrane potential (Δψm) were detected by flow cytometry. The reactive oxygen species (ROS) production in AC16 cells were determined with the ROS-sensitive fluorescent probe. Meanwhile, total intracellular levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in AC16 cells were detected with commercially available kits. Western blot was used to evaluate the activation of c-Jun N-terminal kinase (JNK) and p38 signaling pathways.
Results: 1) Compared with the control group, AC16 cell viability was decreased significantly in the CoCl2 group following the treatment with 500 μmol/L CoCl2 (P<0.01); 2) Compared with the control group, AR value in AC16 cells was increased significantly in the CoCl2 group, while Δψm was decreased significantly (all P<0.01). Compared with the CoCl2 group, AR value in AC16 cells was decreased significantly in the propofol+CoCl2 group, while Δψm was increased significantly (both P<0.05); 3) Compared with the control group, the levels of ROS and MDA were increased significantly, and the level of SOD was significantly decreased in the CoCl2 group (all P<0.01). Compared with the CoCl2 group, the ROS and MDA levels in the propofol+CoCl2 group were increased significantly and the SOD levels were decreased significantly (all P<0.05); 4) Compared with the control group, the phosphorylation levels of JNK and p38 were increased significantly (both P<0.05) in the CoCl2 group. Compared with the CoCl2 group, the phosphorylation levels of JNK and p38 were decreased significantly in the propofol+CoCl2 group (both P<0.05).
Conclusion: The pretreatment with propofol may protect human cardiac AC16 cells from the chemical hypoxia-induced injury through regulation of JNK and p38 signaling pathways.

Objective To observe the effect of creatine phosphate sodium on BIS and recovery quality during general anesthesia emergence period in elderly patients.Methods Sixty ASA Ⅰ or Ⅱpatients,31 males,29 females,aged 65-80 yr undergoing transabdominal cholecystectomy by general anesthesia were randomly allocated into two groups(n=30 each):group creatine phosphate (P)and group control(C)according to random numbers generated by computer.Patients were intravenously infused with 1.0 g creatine phosphate sodium melted in 100 ml normal saline or only 100 ml normal saline in group P or C respectively in thirty minutes at the same time of surgical incision.The heart rate(HR)and bispectral index(BIS)were recorded before anesthesia induction (T0 ),during sputum aspiration (T0 ),during extubation (T2 )and 1(T3 ),5(T4 ),10(T5 ),15 minutes (T6 )after extubation. The dosage of propofol,remifentanil and cisatracurium,anesthesia duration,operation time,awake time,extubation time,recovery time of consciousness and Steward recovery scores on T3-T6 were also recorded,and the occurrence of tachycardia during the operation was observed at the same time. Results Compared with T0 ,the BIS value were lower significantly and HR were significantly in-creased on T1-T4 in the two groups(P <0.05).Compared with group C,the BIS value were signifi-cantly higher in group P on T1-T4 (P <0.05).Compared with group C,awake time,extubation time, recovery time of consciousness significantly shortened in group P (P <0.05).There were six cases of tachycardia occurring in group C which were significantly higher than two cases in group P (P <0.05).Steward recovery scores on T3 and T4 were also higher in group P (P <0.05).Conclusion Not only can 1.0 g creatine phosphate sodium administered during transabdominal cholecystectomy im-prove the BIS value of general anesthesia recovery period and recovery quality,but also effectively re-duce the incidence rate of tachycardia during operation in elderly patients.

The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO₂ of S group were significantly higher before CPB time of rewarming than that before SGB (P < 0.05), much higher than corresponding non-blocked side rSO₂ before CPB (P < 0.05), and much higher than rSO₂ level in group C before CPB and after CPB (P < 0.05). The non-blocked side rSO₂ in group S before anesthesia were much lower than basic levels and those in group C (P < 0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO₂ compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.

Objective To investigate the effect of IL-1 7A on lipopolysaccharide (LPS)-induced neuroinflammation and fear conditioning test.Methods Among 70 male SD rats aged 18 months, firstly,thirty rats were randomly divided into five groups:control group(group A),LPS 6 h group (group B),12 h group(group C),24 h group(group D),48 h group(group E).Group A were injected intraperitoneally with normal saline and groups B,C,D and E were injected with LPS 500 μg/kg.Ani-mals of groups A,B,C,D and E were killed respectively after LPS injection and their hippoeampus tis-sue was detected for the concentration of IL-1 7A.Secondly,forty rats were randomly divided into 4 groups:control group(group O),IL-1 7A antibody group(group P),LPS group (group Q),IL-1 7A antibody+LPS group(group R).Group P and group R were injected intracerebroventricularly with IL-1 7A antibodies 3 μl (200 μg/μl),groups O and Q were injected equal volume of normal saline.30 min later,groups Q and R were injected intraperitoneally with LPS 500 μg/kg,groups O and P were in-jected equal volume of normal saline.24 h later,contextual fear conditioning test was performed. Then,all animals were killed and their hippocampus tissue would be detected for the concentration of TNF-αand IL-6,as well as the expression of Iba1-positive cells.Results The concentration of IL-1 7A of groups B,C,D and E increased significantly compared with group A (P <0.01 ),there was no difference between groups E and A.The freezing time of groups Q and R was significantly shortened than that in group O(P <0.01 or P <0.05 ),the freezing time of group R was significantly longer than that in group Q(P <0.01).The concentration of TNF-αand IL-6 of groups Q and R was obvi-ously higher than group O(P <0.01 ),the concentration of TNF-α and IL-6 of group R lower than group Q(P <0.01).The expression of Iba1-positive cells in hippocampal area CA1 of groups Q and R was obviously increased compared with group O(P <0.01).Compared with group Q,the expression of Iba1-positive cells in hippocampal area CA1 of group R were obviously decreased (P < 0.05 ). Conclusion IL-1 7A is implicated in the early stage of LPS-induced neuroinflammation and the chan-ging of freezing time in contextual fear conditioning in aged rats.

Objective To improve the understanding of cutaneous intravascular natural killer/T-cell lymphoma (CIVNKTC). Methods Clinical data on five cases of CIVNKTC were collected. The histopathological feature, treatment and prognosis of CIVNKTC were retrospectively analyzed and discussed. Results Of the 5 patients, 1 was male and 4 were female. The age of onset ranged from 38 to 83 years (average, 56.2 years). All the patients presented with multiple plaques and nodules as the primary symptoms. Histopathological examination revealed vasodilatation in the dermis and subcutaneous tissue, as well as atypical lymphoid cells with large hyperchromatic nuclei containing 1-2 small nucleoli in dilated veins. Immunohistochemical studies of tumor cells showed positive staining for CD3ε, cytotoxic proteins (including T cell-restricted intracellular antigen-1, granzyme B and perforin)and Epstein-Barr virus(EBV)-encoded microRNA, but negative staining for cytokeratin, CD20, CD79a, CD4 and CD8. Furthermore, the tumor cells stained positive for CD56 in two patients. Among the 5 patients, only 2 received chemotherapy and the remaining received no treatment. During a 24-month follow-up, 4 patients died, and only 1 survived with the tumor. Conclusion CIVNKTC is a rare extranodal Hodgkin′s lymphoma with distinct histologic manifestations and immunophenotypes, rapid and aggressive clinical course, and poor prognosis.

ObjectiveTo study the diagnostic value of sonographic “Leopard pattern” sign in breast hyperplasia.MethodsTwo hundred and twenty-three female patients in Beijing Friendship Hospital from October 2012 to April 2013 were choosen. All the cases were diagnosed as mammary gland hyperplasia clinically, and their breast ultrasound images show the breast imaging-reporting and data system (BI-RADS) grad was 0 or 1. These patients were divided into 3 groups according to their age, Group A: 20 to 35 age (36 cases), Group B: 36 to 50 age (102 cases), and Group C: order than 50 year-old (85 cases). The pathological diagnosis were obtained by ultrasound guided breast biopsy. With pathological diagnosis as the gold standard and “Leopard sign” as ultrasound diagnostic criteria, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were calculated. The consistency between the ultrasonic and the pathological diagnosis were analyzed by Kappa statistical test.ResultThe diagnostic consistency test of the total sample of 223 cases: in terms of the ultrasonic Leopard sign” for the diagnosis of breast hyperplasia, the sensitivity was 69% (59/85),the specificity was 46% (64/138), the accuracy was 55% (123/223), the positive predictive value was 44% (59/133), the negative predictive value was 71% (64/90), the consistency was poor (Kappa=0.14,P<0.05). Group A:the sensitivity was 90% (18/20), the specificity was 50% (8/16),the accuracy was 72% (26/36), the positive predictive value was 69% (18/26), the negative predictive value was 80% (8/10), the consistency was good (Kappa=0.42, P<0.05);Group B:the sensitivity was 70% (33/47), the specificity was 49% (27/55),the accuracy was 59% (60/102), the positive predictive value was 54% (33/61), the negative predictive value was 66% (27/41), the consistency was poor (Kappa=0.19,P<0.05); Group C: the sensitivity was 44% (8/18), the specificity was 43% (29/67), the accuracy was 44% (37/85), the positive predictive value was 17% (8/46), the negative predictive value was 74% (29/39), the consistency was poor (Kappa=0.08,P<0.05).Conclusion“Leopard pattern” sign is not suitable as an independent standard in diagnosing breast hyperplasia disease.
