Objective To investigate the change and clinical application value of plasma D‐dimer in acute cerebral hemorrhage . Methods The plasma D‐dimer level was detected in 78 individuals of healthy physical examination(healthy control group) and 82 patients with acute cerebral hemorrhage .Results The plasma D‐dimer levels at admission(0 h) had no statistical difference among various groups(P> 0 .05) ;the D‐dimer level at 24 ,48 ,72 h in the small cerebral hemorrhage group was significantly higher than that in the healthy control group(P< 0 .05) ;the D‐dimer level in the massive cerebral hemorrhage group was significantly higher than that in the small cerebral hemorrhage group(P< 0 .05) ;the D‐dimer level in the small cerebral hemorrhage group reached the peak at 24 h ,while which in the massive cerebral hemorrhage group reached the peak at 48 h and was positively correlated with the intracranial hemorrhage volume(r= 0 .914 ,P= 0 .000 < 0 .05) .Conclusion The plasma D‐dimer level in the patients with acute cer‐ebral hemorrhage is obviously increased and shows the increasing trend with the intracranial hemorrhage volume increase ;the more the intracranial hemorrhage volume ,the longer the persistence time of high D‐dimer level .Therefore detecting plasma D‐dimer level has an important significance for monitoring the condition in the patients with acute cerebral hemorrhage .

50.0%.CONCLUSION:The extensive use of antibacterials results in increased drug resistance,while rational use of antibiotics is the key of decreasing drug resistance and multidrug resistance.It is of great importance to analyze the variation of bacterial drug resistance in area hospital.

Patients with end-stage liver disease have an increased risk of developing bacterial infections, resulting in an increase in the number of hospitalizations and medical expenses, a decline in the quality of life of patients, and an increased fatality rate. Bacterial infections in patients with end-stage liver disease is mainly due to the falling off the body's immune response causing respiratory infections, spontaneous bacterial peritonitis, urinary tract infections and gastrointestinal infections. The diagnosis of bacterial infection is more challenging because the occurrence of infection shows no typical symptoms and signs. The examination of some biological markers has important clinical significance for early diagnosis. The clinical prognosis is entirely marked on the patient conditions, the effective control of infection, appropriate broad-spectrum antibiotics, and empiric therapy. Antibiotics are the choice, but also need to be alert against drug-induced liver damage.

Objective To discuss the clinical value of interventional management before surgical therapy for massive gastrointestinal hemorrhage, and to compare the clinical efficacy and re-bleeding rate between hypophysin infusion group and embolization group. Methods During the period of June 1998-Apr.2009, 31 patients with massive gastrointestinal hemorrhage in our institution underwent preoperative interventional managements before they received surgical treatment. According to DSA manifestations, the patients underwent trunsarterial hypophysin infusion or transcatheter embolization as interventional management. The clinical efficacy of interventional procedures and its influence on the surgery were evaluated, and the hemostasis rate and re-bleeding rate were compared the two kind of intervention managements. The numeration data were analyzed with Fisher's exact test, and the SPSS 11.0 was used as statistical software. Results The interventional managements were successfully performed in all the 31patients, with a total hemostasis rate of 83.9% (26/31) and a total re-bleeding rate 30.7% (8/26). The hemostasis rate and re-bleeding rate of hypephysin infusion group and embolization group were 69.2% (9/13), 94.4% (17/18) and 44.4% (4/9), 23.7% (4/17), respectively. All the 31 patients received surgery after interventional therapy, of which selective operation was carried out in 20. Neither surgery-related or intervention-related serious complications nor death occurred. Conclusion Preoperative interventional managements can provide patients with massive gastrointestinal hemorrhage with valuable chance of a successful surgery, enable the physician to take a selective operation to replace an emergency one, as a result, the surgical risk will be greatly reduced. Therefore, it is worth popularizing the preoperative interventional managements in clinical practice.

Hepatitis B virus (HBV) carrier woman of childbearing age with high viral load is an important source of vertical transmission of hepatitis b virus from mother-to-child in China. Routine blockade with immunoglobulin combined with hepatitis B vaccine is used for neonates born to pregnant women with high viral load of hepatitis B virus, but in some cases, immunoprophylaxis fails. The main application of antiviral drugs in pregnancy is to reduce the serum viral load, thereby significantly improve the blocking rate of vertical transmission between mother and infant. Current evidence suggested that if the maternal age is less than 30 years old, with no obvious liver fibrosis or cirrhosis and there is no increase in ALT level >2ULN( upper limit of normal) during the treatment, the treatment with antiviral drugs can be stopped after delivery immediately. Additionally, ALT level should be examined at 4, 12 and 24 weeks after stopping the drug. Antiviral therapy for the occurrence of hepatitis attack should be given if criteria for HBV treatment are met.

Objective To investigate anticoagulation and security of heparin and low molecular weight heparin applied to the carotid artery after CASA, to provide a reference for clinical anticoagulation. Methods From January 2010 to December 2013,120 cases of implementation of CASA surgical patients with carotid artery were selected,according to anticoagulation method they were divided into control group and observation group, control group had 54 patients, the implementation was continuous intravenous infusion of heparin for 3 days; observation group had 66 patients with sub-cutaneous low molecular weight heparin anticoagulation, one injection for 12 h, lasted for three days, before surgery,24 h,72 h after surgery,anti-Xa activity were detected in patients,activated partial thromboplastin time(APTT),pro-thrombin time (PT), complications were compared between the two groups. Results Anti-Xa activity of observation group and control group after 24 h were (1.204±0.413) IU/mL, (1.428±0.512) IU/mL, the difference was statistically significant(t=3.189,P=0.037), anti-Xa activity levels after 72 h of observation group and control group were (1.314±0.533)IU/mL,(1.684±0.687) IU/mL, the difference was statistically significant (t=4.218, P=0.030); in observation group,before surgery,24 h, 72 h after surgery APTT were(27.93±3.86)s,(37.97±5.14)s,(37.73±4.28)s, differences were statistically significant before and after surgery (t=6.453, P=0.009; t=6.449,P=0.010); in the control group,be-fore surgery,24 h,72 h after surgery APTT were(27.64±3.24)s,(38.34±4.55)s,(38.21±4.41)s,differences were statisti-cally significant before and after surgery(t=6.534,P=0.007;t=6.530,P=0.007);preoperative and 24 h,72 h postoper-ative at the same period for observation group and control group there were no significant difference(t=0.927,P=0.197;t=1.023, P=0.143; t=0.993, P=0.176); in observation group before surgery,24 h,72 h after surgery for PT compared with the control group the difference was not statistically significant (P>0.05); in observation group complication rate was 9.09%(6/66)and the control group was 7.41%(4/54)the difference was no statistically significant(χ2=1.034,P=0.114).Conclusion Low molecular weight heparin and unfractionated heparin used in carotid surgery CASA have similar anti-coagulant effect,low molecular weight heparin is slightly lower in anti-Xa activity,but it's easy to monitor and control to ensure the safety of the treatment.

Objective To increase the awareness of ectopic ACTH syndrome in patients with thymus carcinoid. Methods Clinical manifestations, especially atypical presentation of ectopic ACTH syndrome, laboratory findings and imaging data (chest X-ray and CT, etc.) in 6 patients were analysed. Results In all 6 patients, the thymus tumors removed were pathologically proved to be thymus carcinoid. Conclusion Patients having typical manifestations of Cushing′s syndrome with hypokalemia, edema, proteinuria and equivocal result of dexamethasone inhibition test, should be considered as ACTH syndrome. And thymus carcinoid seems to be the cause of the disease.

The incidence and mortality of hepatocellular carcinoma (HCC) is very high in China, which seriously threatens human life and health. There were limited treatment options for advanced HCC in the past, and the overall survival of HCC patients was poor. In recent years, immuno-therapy and targeted therapy have been recommended as effective means for the treatment of advan-ced HCC. The authors report a case of advanced huge HCC which has achieved a maintained partial response for 6 months after the treatment of atezolizumab combined with bevacizumab. The tumor shrunk by 32.4% and 47.5% after 3 and 6 months of treatment. Besides, the alpha-fetoprotein and abnormal tumor protein value of the patient continued to decrease without any adverse reactions. The treatment is evaluated as partial response and patients has a good short-term effect.
