Fresh blood of Tibetan sheep was subjected to protein separation and spray drying, and the effects of drying process on water content, yield and nitrogen soluble index of plasma powder from blood of Tibetan sheep were investigated. The results showed that the optimum separation parameters were a centrifugal speed at 6 000 r/min, centrifugal time of 20 min, a mass fraction of dry matter of 20%, an inlet air temperature at 180 ℃ and a feed rate at 400 ml/h, under which the plasma protein was a pale yellow powdery solid, indicating a good separation effect. 展开更多

Objective To set up a new grading system of intraventricular hemorrhage (IVH) and determine the value of predicting the probability of post-hemorrhagic hydrocephalus (PHH) in IVH. Methods We first modified the Graeb criteria, then compared the value of prediction for PHH assessed by the Graeb criteria with the modified Graeb criteria. One hundred and thirty one IVH patients were divided into two groups: the upper group (n=67) and the lower group (n=64). Gold standard of PHH was assessed by CT scan or by out-drainage. The diagno-stic parameters such as sensitivity (SE), specificity (SP) were analyzed. In the cutoff point of SE and SP curves, diagnostic efficiency (DE), and Kappa value (K) were analyzed. The probability of PHH was estimated by binary logistic regressions. Results In all ventricular group, to Graeb criteria in the cutoff point, SE, SP, and K was 0.78, 0.84, and 0.60; and to modified Graeb criteria SE, SP, and K was 0.90, 0.84, and 0.74 respectively. The probability of PHH from point of 3-12 was 0.011, 0.032, 0.085, 0.212, 0.435, 0.689, 0.865, 0.949, 0.981, and 0.994 respectively according to modified Graeb criteria. Conclusion The modified Graeb criteria combined with logistic regression were useful methods to assess the severity of IVH and to predict the probability of PHH in IVH. 展开更多

Objective To estimate the frequency of various risk factors for overall stroke and to identify risk factors for cerebral infarction (CI) versus intracerebral hemorrhage (ICH) in a large hospital-based stroke registry. Methods Data from a total of 3901 patients, consisting of 3525 patients with CI and 376 patients with ICH were pros-pectively coded and entered into a computerized data bank. Results Hypertension and smoking were the most prominent factors affecting overall stroke followed by mild internal carotid artery stenosis (< 50%), hypercholesterolemia, transient ischemic attacks (TIAs), diabetes mellitus, and cardiac ischemia. Univariate analysis showed that factors in male significantly associated with CI versus ICH were old age, a family history of stroke, and intermittent claudication; whereas in female the factors were oral contraception and migraine. By multivariate analysis, in all patients, the factors significantly associated with CI as opposed to ICH were smoking, hyperch-olesterolemia, migraine, TIAs, atrial fibrillation, structural heart disease, and arterial disease. Hypertension was the only significant factor related with ICH versus CI.Conclusions The factors for ischemic and hemorrhagic stroke are not exactly the same. Cardiac and arterial disease are the most powerful factors associated with CI rather than ICH. 展开更多

Objective: To evaluate the therapeutic efficacy of injecting highly agglutinative staphylococcin (HASL) and cisplatin into pericardial cavity of lung cancer patients with pericardial effusion. Methods: 81 patients were randomized into two groups: 45 in the experimental group (HASL and Cisplatin) and 36 in the control group (Cisplatin). At first pericardial effusion was drained out from a intrapericardial catheter and then different drugs were infused, respectively. 24 h after perfusion the draining continued again until drainage quantity was less than 30 mL every day. The draining lasted 10–15 days. Results: The response rate was 91.1% for the experimental group and 80.6% for the control group. There was no significant difference between the two groups (P>0.05). The complete remission was 77.8% for the experimental group and 52.8% for the control group, which was statistically significant difference (P<0.05). The adverse effects were myelosuppression and nausea and vomiting, which were 35.6% and 40.0% in the experimental group and 72.2% and 66.7% in the control group, respectively (P<0.01, P<0.05). Conclusion: Inject- ing HASL and cisplatin into pericardial cavity may be a better way to control pericardial effusion of lung cancer. 展开更多

Blood loss and blood transfusion requirement are important quality control indicators of cardiovascular surgery and cardiovascular anesthesia.Patient blood management(PBM)is an evidence-based,multidisciplinary approach to optimizing the care of patients who may need transfusion,which encompasses anemia management,hemodilution,cell salvage,hemostatic treatment,and other approaches to reducing bleeding and minimizing blood transfusion.PBM in cardiovascular surgery is a"team sport"that involves cardiac and vascular surgeons,anesthesiologists,perfusionist,intensivists,and other health care providers.The current work provides an overview of evidence and practice of PBM at Fuwai Hospital.Implementation of PBM should also take local resource availability and costeffectiveness of different devices,drugs,technologies,and techniques into consideration. 展开更多

Cognitive damage in heart failure (HF) involves different domains thus interfering with the ability for single patient to self-care and to cope with treatment regimens, modifying symptoms and health behaviours. Many cerebral and functional changes were detected in brain imaging, involving areas of both grey and white matter deputed to cognition. Although various instruments are available to explore cognition, no consensus was obtained on better tools to be used in HF population. Reduction in cerebral blood flow, decreased cardiac output, altera-tions of cerebrovascular reactivity and modification of blood pressure levels are the main features involved in the etiopathogenetic mecha-nisms of cognitive deficit. Several cardiac variables, laboratory parameters, demographic and clinical elements were studied for their possible relation with cognition and should be properly evaluated to define patients at increased risk of impairment. The present review gathers avail-able data pointing out assured information and discussing possible areas of research development. 展开更多
