Objective: To explore the blood-saving effect of autologous platelet-rich plasma (PRP) back-transfusion in patients with Stanford type A aortic dissection surgery. Methods: A total of 59 consecutive patients who received Stanford type A aortic dissection surgery in our hospital from 2013-01 to 2015-10 were studied. The patients were at the age of (50±6) years with mean body weighting at (80±12) kg and were randomly divided into 2 groups: Traditional (T) group,n=31 and Autologous PRP back-transfusion (P) group,n=28. Blood levels of Hb, platelet counts, PT, APTT were measured at pre-induction of anesthesia (T1), before CPB (T2), prior ifnishing of CPB (T3) and at 1 h (T4), 24 h (T5), 48 h (T6) after the operation. The in-operative, 48 h post-operative volumes of allogeneic blood transfusion and the volume of chest tube drainage at 48h after operation were recorded; the complication occurrence at peri-operative period was recorded. Results: In P group, whole blood processing volume was (1269±197) ml, PRP volume was (753±78) ml, PRP separation time was (35±9) min and the separated platelets were about (22±3)% of total platelet counts. Compared with T group, P group had decreased Hb at T2 (131.0±15.0) g/L vs (101.0±10.0) g/L, decreased platelet counts at T3 (115.0±51.0)×109 /L vs (83.0±23.0)×109/L, while increased platelet counts at T4 (103.0±25.0)×109/L vs (151.0±27.0)×109/L, T5 (105.0±25.0)×109 /L vs (147.0±39.0)×109/L and T6 (101.0±26.0) ×109/L vs (149.0±35.0)×109/L, allP<0.05; P group presented reduced PT at T4 (17.6±2.1) s vs (14.1±1.1) s and T5 (17.6±2.7) s vs (13.5±0.8) s, allP<0.05. The in-operative transfusions of platelet, plasma, cold precipitation and post-operative transfusions of red blood cells, platelets, plasma, cold precipitation and the volume of chest tube drainage at 48h after operation were less in P group,P<0.05. Compared with T group, P group had the lower rates of acute post-operative lung injury (32.1% vs 19.4%), shorter mechanical ventilation time (69.1±5.9) h vs (43.1±1.5) h and ICU staying time (8.1±2.8) d vs (5.3±1.1) d, allP<0.05. Conclusion: Autologous PRP back-transfusion could reduce the post-operative bleeding and allogeneic blood transfusion for Stanford A aortic dissection surgery, it has obvious blood-saving effect.

ObjectiveTo study the effect of anticoagulant therapy with low molecular weight heparin (LMWH) on coagulation and inflammation markers in sepsis patients.Methods A prospective randomized controlled trial was conducted. Sixty sepsis patients admitted to intensive care unit (ICU) of Zhengzhou University People's Hospital from March 2012 to May 2014 were divided into control group and observation group, with 30 cases in each group. The observations were begun as soon as the diagnosis of sepsis was established, and the observation time was 7 days. All sepsis patients were treated according to the 2008 international sepsis treatment guidelines. Every patient in the observation group was subcutaneously injected with LMWH 0.6 mL on the first day of ICU admission, twice a day for 7 days. The blood from peripheral vein was collected at 1, 3, 5, 7 days of treatment, and CD62p, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme linked immunosorbent assay (ELISA), D-dimmer was determined by immunoturbidimetry, acute physiology and chronic health evaluationⅡ (APACHEⅡ) score was recorded, and incidence of multiple organ dysfunction syndrome (MODS) was also evaluated.Results There were no significant differences in values of all parameters, including CD62p, D-dimmer, IL-6, TNF-α, and APACHEⅡ score at 1 day of treatment. The values of all parameters in observation group were gradually decreased. CD62p at 3 days of treatment and D-dimmer, IL-6, TNF-α, and APACHEⅡ score at 5 days of treatment were significantly lower than those at 1 day of treatment. The values in the control group were decreased at first and then increased, as D-dimmer, IL-6 and TNF-α were significantly higher on the 5th day than those at 1 day of treatment. Compared with control group, CD62p, D-dimmer, IL-6, TNF-α and APACHEⅡ score on the 7th day of treatment were significantly lowered in observation group [CD62 (μg/L): 22.64±2.88 vs. 31.52±2.81, D-dimmer (g/L): 1.32±0.46 vs. 4.79±0.82, IL-6 (ng/L): 5.84±1.87 vs. 49.64±3.12, TNF-α (ng/L): 21.04±3.15 vs. 130.58±6.26, APACHEⅡ score: 9.71±2.02 vs. 14.17±2.38, allP< 0.05]. Correlation analysis showed that in observation group, CD62p, D-dimmer, IL-6, and TNF-α were positively correlated with APACHEⅡ score (r value was 0.907, 0.868, 0.880, 0.693, respectively, all P=0.000). The incidence of MODS in observation group was significantly lower than that in the control group [26.7% (8/30) vs. 46.7% (14/30),χ2=3.943,P= 0.028].Conclusions LMWH, which was given early in sepsis, can significantly down-regulate the expression of CD62p, D-dimmer, IL-6 and TNF-α, and reduce the incidence of MODS. Some indicators regarding coagulation and inflammation can be used as supplementary indicators to severity scores, and it may be able to improve the accuracy of scoring systems for sepsis.

BACKGROUND AND OBJECTIVES: The overall purpose of this study was to investigate the role of cytochrome C oxidase (CcO) in preventing ischemia reperfusion-induced cardiac injury through gaseous signaling molecule pathways. MATERIALS AND METHODS: We used CcO inhibitor, potassium cyanide (KCN) to mimic the pre-treatment of gaseous signaling molecules in a global ischemia/reperfusion (IR) injury model in rats. Intracellular reactive oxygen species (ROS) was determined by measuring mitochondrial H2O2 and mitochondrial complex activity. RESULTS: KCN pre-treatment led to decreased infarction area after IR injury and improved cardiac function. KCN pre-treated group challenged with IR injury was associated with reduced ROS production through inhibition of activity and not downregulation of CcO expression. In addition, KCN pre-treatment was associated with enhanced expression and activity of mitochondrial antioxidase, suggesting the role of CcO in regulating IR injury through oxidative stress. CONCLUSION: KCN pre-treatment reduced the severity of IR injury. The potential mechanism could be increased endogenous anti-oxidase activity and consequently, the enhanced clearance of ROS.

OBJECTIVETo identify the genetic cause for a Chinese Han family affected with primary hypertrophic osteoarthropathy.
METHODSWhole blood and urine samples were collected from a patient and 7 unaffected relatives of the family. The coding sequences and intron/exon boundaries of HPGD and SLCO2A1 genes of the patient were amplified with polymerase chain reaction and sequenced. The genotypes of relatives were subsequently verified. Urinary prostaglandin level was measured with enzyme-linked immunosorbent assay (ELISA).
RESULTSA homozygous 2-bp deletion in HPGD gene (c.310_311delCT, or p.L104AfsX3) was detected in the patient, and 5 heterozygous carriers were identified in the relatives. The urinary prostaglandin E2 (PGE2) level was significantly elevated (P<0.01), while PGE-M was significantly reduced (P<0.01) in the patient.
CONCLUSIONPrimary hypertrophic osteoarthropathy in this family is caused by a homozygous mutation (c.310_311delCT) in the HPGD gene.

Objective To investigate the clinical features and risk factors of multidrug-resistant bacteria (multi drug resistant organisms, MDROs) infection in Department of Neurosurgery, and to provide evidence for the prevention and control of MDRO infection. Methods Data from 437 cases of infection in hospitalized patients on January 2012-2016 year in December Third Affiliated Hospital of Guizhou Medical University were retrospectively analyzed. Patients were divided into MDROs group and non MDROs group based on the results of MDROs detection. Multi factor Logistic regression analysis model was used to analyze risk factors. Results The infection rate of MDROs was 35.51%, and the detection rate of MDROs was 33.23% . ESBLs, CR-AB and MRSA were the most common bacterial species, and the infection of respiratory tract, urinary tract and wound infection were the main infection sites. Multivariate logistic regression analysis showed that hospitalization time >20 d, level of consciousness (coma), occupancy of ICU ≥7 d, ventilation (invasive), number of antibiotics used≥3, combined use of antibiotics≥3, mechanical ventilation Time≥7 d were possible risk factors for MDROs infection in neurosurgical patients (P<0.05). Conclusion The situation of MDROs infection in neurosurgery is severe. To reduce MDROs infection, it is important to shorten unnecessary hospitalization time, promptly assess and transfer out of ICU as soon as possible, improve microbial examination, avoid frequent change of antibiotics or unnecessary use of use of broad-spectrum antibiotics, reduce unnecessary mechanical ventilation time, change to non-invasive ventilation as far as possible when the condition permits, focus on patients with poor consciousness, and prevent aspiration by mistake.

Objective:To compare the application effect of blue dye single tracer and blue dye combined with nuclide double tracer in sentinel lymph node biopsy (SLNB) of breast cancer surgery.Methods:A total of 92 breast cancer patients in Shandong Cancer Hospital and Institute from November 2017 to October 2019 underwent methyleneblue dye combined with 99Tc m sulfur colloid nuclide double tracer in SLNB, while other 92 cases in Jining First People Hospital underwent blue dye single tracer. The number of SLN detection, detection rate, accuracy rate, sensitivity, and false negative rate of the two groups were compared. The impacts of age, menstruation, tumor location, tumor size, clinical stage, pathological type, and estrogen receptor (ER), progesterone receptor (PR), human epidermal receptor 2 (HER-2), molecular typing, dynamic enhanced magnetic resonance imaging (DCE-MRI)on the detection rate of SLN were analyzed. Results:The number of detection, detection rate, accuracy, sensitivity, and false negative rate of the blue dye single tracer group were 3.20±1.10, 90.22%, 93.48%, 95.24% and 4.76%, respectively; the double tracer group were 3.37±1.02, 92.39%, 95.65%, 95.65% and 4.35%, respectively, without significant difference (all P>0.05). In different age, menstrual condition, tumor location, clinical stage, pathological type, ER, PR, HER-2 expression and molecular typing, the detection rate of single tracer group and double tracer group had no significant difference (all P>0.05). However, in the tumor size of 2-5 cm and without DCE-MRI examination, the detection rate of single tracer group was significantly lower than that of double tracer group. Conclusion:The effect of blue dye single tracer in detecting SLN of breast cancer is equivalent to that of double tracer method, which is worthy of promotion and application in primary hospitals.
