Objective To investigate the risk factors of severe hemolysis during extracorporeal membrane oxygenation (ECMO). Methods The clinical data of adult patients undergoing ECMO after cardiac surgery admitted to Fuwai Hospital from December 2010 to October 2015 were retrospectively analyzed. Demographic characteristics, renal function, primary disease, operation data, ECMO related data and outcomes were recorded. Patients were divided into normal free hemoglobin (FHB) group (FHB ≤ 500 mg/L) and severe hemolysis group (FHB > 500 mg/L) according to the FHB level during ECMO support. The parameters before and after ECMO support were compared between the two groups. Logistic regression was used to identify the independent risk factors of severe hemolysis. Results A total of 81 patients including 19 patients with severe hemolysis was enrolled, and 62 in normal FHB group. There was no difference in cardiopulmonary bypass (CPB) time, clamping time, lactate level before ECMO, cardiopulmonary resuscitation, intra-aortic balloon pump use and central catheter insertion between two groups. The maximums of serum creatinine (SCr) and FHB levels were higher in severe hemolysis group as compared with those in normal FHB group [maximal SCr (μmol/L): 281.02±164.11 vs. 196.67±87.31, maximal FHB (mg/L): 600 (600, 700) vs. 200 (100, 300)], the incidence of clots in circuit or oxygenator, infection, and hemofiltration in severe hemolysis group was increased [26.3% (5/19) vs. 4.8% (3/62), 31.6% (6/19) vs. 12.9% (8/62), 36.8% (7/19) vs. 14.5% (9/62), all P < 0.1]. As well as outcomes including the rate of site of surgery or intubation bleeding and acute renal failure [ARF, 57.9 % (11/19) vs. 30.6% (19/62), 94.7% (18/19) vs. 41.9% (26/62)], and the survival rate was lowered [10.5% (2/19) vs. 51.6% (32/62), all P < 0.05]. As result of univariate analysis, clots in circuit or oxygenator, infection and hemofiltration were associated with severe hemolysis. It was showed by logistic regression analysis that the clots in circuit or oxygenator was a risk factor of severe hemolysis during ECMO [odds ratio (OR) = 6.262, 95% confidence interval (95%CI) = 1.244-31.515, P = 0.026]. Conclusions The clots in circuit or oxygenator were independent risk factors of severe hemolysis during ECMO. Severe hemolysis can induce the increase of the rate of bleeding in the operation site or intubation and the rate of ARF, and decrease of the survival rate.

Objective To explore the clinical features of chronic myelogenous leukemia (CML) combined with solid malignant neoplasms. Methods The clinical data of 8 CML patients with solid malignant neoplasms who were admitted to the Affiliated Tumor Hospital of Zhengzhou University, the Central Hospital of Nanyang City, the First Affiliated Hospital of Science and Technology University of Henan, and the Central Hospital of Xinxiang City from August 2006 to August 2018 were analyzed retrospectively. The clinical features, treatment and prognosis of the patients were summarized with the review of literature. Results Among the 8 patients, 3 were male and 5 female, aged 40-76 years, with a median of 50 years old. Seven cases were in CML chronic phase, and 1 was in accelerated phase. Seven patients were treated with tyrosine kinase inhibitor (TKI), and only 1 patient was treated with hydroxyurea. In 8 patients, two cases presented with synchronous multiple primary cancer (SMPC), 6 cases presented with heterochrony multiple primary cancer (HMPC). two patients received the operation, 1 patient received the operation and chemotherapy, 4 patients received chemotherapy, and 1 patient received the isotope treatment. One SMPC patient died and another one was under treatment, and 6 HMPC patients were under treatment. ConclusionsThe relationship between CML and solid malignant neoplasm is under discussion, but patients with CML and solid malignant neoplasm are not unusual. Clinicians should raise awareness to avoid misdiagnosis. The treatment should follow the two main lines that are comprehensive treatment and individualized treatment.

Objective To observe the effects of Angelicae Sinensis Radix-Paeoniae Radix alba combined with bone marrow mesenchymal stem cells(BM-MSCs)transplantation on liver inflammation and hepatocytes regeneration in non-alcoholic steatohepatitis(NASH)associated cirrhosis;To discuss its possible mechanism.Methods West diet combined with carbon tetrachloride was used to prepare the NASH related cirrhosis model.The mice were randomly divided into control group,model group,Angelicae Sinensis Radix-Paeoniae Radix alba group,BM-MSCs group,and Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group,with 12 mice in each group.After successful modeling,corresponding interventions were given according to grouping for 4 consecutive weeks.HE staining was used to observe the morphology of liver tissue;the contents of serum ALT,AST,TBil,TG,ALB,AFP,as well as the contents of IL-1β,TNF-α and HGF in liver tissue were detected;RT-qPCR was used to detect TLR9,MyD88,TRAF6 and NF-κBp65 mRNA expression in liver cells;primary liver cells were separated,CpG ODN 2216 stimulation was induced in vitro,cells supernatant was extracted,and IL-1β and TNF-α content were detected.Results Compared with the control group,inflammatory cell infiltrated in liver tissue of model group mice,accompanied by hepatocyte necrosis and collagen deposition,forming pseudo lobules;the contents of serum ALT,AST,TBil and TG increased,the content of ALB decreased,the content of HGF in liver tissue decreased,the contents of IL-1β and TNF-α increased,with statistical significance(P<0.05);the mRNA expressions of TLR9,MyD88,TRAF6 and NF-κBp65 in liver cells increased(P<0.05),and the contents of IL-1β and TNF-α in cells supernatant increased after CpG ODN 2216 induction(P<0.05).Compared with the model group,the inflammatory infiltration in liver tissue and necrosis of liver cells were reduced and the degree of liver fibrosis was alleviated in the Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group,the liver tissue damage in Angelicae Sinensis Radix-Paeoniae Radix alba group and BM-MSCs group were slightly improved;except for the TG content in BM-MSCs group,all detection indicators showed significant improvement in each intervention group(P<0.05).Compared with the Angelicae Sinensis Radix-Paeoniae Radix alba group and BM-MSCs group,the Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group showed statistical significance in related detection indicators(P<0.05),and demonstrated a synergistic effect.Conclusion Angelicae Sinensis Radix-Paeoniae Radix alba combined with BM-MSCs transplantation could effectively improve the liver function and promote liver cell regeneration.The mechanism is associated with the down-regulation of TLR9/NF-κB signaling pathway expressions and function,the inhibition of inflammatory cytokines secretions,and the improvement of liver inflammatory microenviroment.

Objective: To explore the application value of B-ultrasound examination in gynecological acute abdomen. Methods: From October 2015 to October 2017, 150 patients with suspected gynecological acute abdomen were selected in the People's Hospital of Lishui.The effect of B-ultrasound examination in diagnosis of gynecological acute abdomen was analyzed. Results: The sensitivity, specificity and total accuracy of abdominal ultrasound in the diagnosis of gynecological acute abdomen were 75.00%(99/132), 44.44%(8/18) and 71.33%(107/150), respectively.The sensitivity, specificity and total accuracy of transvaginal ultrasound in the diagnosis of gynecological acute abdomen were 87.12%(115/132), 72.22%(13/18) and 85.33%(128/150), respectively.The sensitivity, specificity and total accuracy of abdominal combined with transvaginal ultrasonography in the diagnosis of gynecological acute abdomen were 98.48%(130/132), 94.44%(17/18) and 98.00%(147/150), respectively.The sensitivity, specificity and total accuracy of abdominal combined with transvaginal ultrasound in the diagnosis of gynecological acute abdomen were significantly higher than those of abdominal ultrasound and transvaginal ultrasound(χ²=8.658, 10.699, 9.075, all P<0.05). The diagnosis of acute pelvic inflammation, ectopic pregnancy, rupture of luteal cyst and torsion of ovarian cyst by abdominal combined with transvaginal ultrasound was better than abdominal ultrasound(χ²=13.748, 5.984, 13.524, 6.874, all P<0.05). Conclusion Abdominal ultrasound and transvaginal ultrasound can be used to diagnose gynecological acute abdomen.However, abdominal combined with vaginal ultrasound is more effective in the diagnosis of gynecological acute abdomen, and it can effectively improve the accuracy of diagnosis.

Objective: To explore the application value of B-mode ultrasound combined with real-time color doppler ultrasound in percutaneous nephrolithotomy and provide guidance for clinical application. Methods: A total of 150 patients underwent percutaneous nephrolithotomy from December 2015 to December 2017 in the People's Hospital of Lishui were selected.According to different ultrasound guidance methods, the patients were divided into two groups.The single group(70 cases) received B-guided puncture.In the combined group(80 cases), B-ultrasound combined with real-time color doppler ultrasound-guided puncture was applied.The incidence of complications and the success rate of lithotomy were compared between the two groups.The changes in renal artery blood flow parameters[end diastolic velocity(EDV), peak systolic velocity(PSV) and resistance index(RI)] before and after surgery in the combined group were observed. Results: The incidence of complications in the combined group was 2.50%(2/80), which was lower than that in the single group[14.29%(10/70)](χ²=7.046, P<0.05). The success rate of stone extraction in the combined group was 98.75%(79/80), which was higher than that in the single group[85.71%(60/70)](χ²=9.336, P<0.01). The EDV and PSV of the renal interlobar arteries of the combined group before and after surgery had statistically significant differences (t=3.794, 5.385, all P<0.05), but the RI had no statistically significant difference (P>0.05). The EDV and PSV of renal segment arteries in the combined group before and after surgery had statistically significant differences (t=4.535, 4.884, all P<0.05), while the RI had no statistically significant difference (P>0.05). The EDV and PSV of renal aorta of the combined group before and after surgery showed no statistically significant differences (all P>0.05), while the RI showed statistically significant difference (t=4.360, P<0.05). Conclusion B-mode ultrasound combined with real-time color doppler ultrasound guidance for percutaneous nephrolithotomy can help reduce the incidence of complications and improve the success rate of stone extraction to a certain extent.

Objective To explore the incidence rate,risk factors and outcome of hyperbilirubinemia in adult cardiac patients supported by extracorporeal membrane oxygenation(ECMO).Methods Clinical data of 89 adult cardiac patients with ECMO in Fuwai Hospital were retrospectively analyzed.All patients were divided into normal group,high bilirubin group and severe high bilirubin group.In a multiple linear regression analysis,logarithmic transformation was performed for non-normally distributed variables.Results The incidence rate of hyperbilirubinemia was 73％,including 30 cases in high bilirubin group and 35 cases in severe high bilirubin group.A multiple linear regression analysis showed that lg(peak TBIL+1)was significantly associated with lg(peak AST+1)(P=0.001),lg(peak free hemoglobin +1)(P=0.003)and TBIL before ECMO(P=0.009).There was also a linear correlation between peak TBIL and TBIL before ECMO support(P=0.011),peak AST(P=0.004)and peak free hemoglobin during ECMO(P<0.001).The patients in severe high bilirubin group had lower platelets during ECMO,and the survival rate was the lowest.Conclusion Hyperbilirubinemia remains common in patients with ECMO,and is associated with low platelet and a high rate of in-hospital mortality.Hemolysis and liver dysfunction during ECMO support and high bilirubin level before ECMO are risk factors of hyperbilirubinemia.
