The sera of 40 normal controls,61 cases of various malignant diseases except pancreatic cancer,53 cases of various henign diseases,and 33 cases of pancreatic cancer were examined with ELISA to determine the serum level of pancreatic cancer-associated antigen(PCAAc).Its normal value was 12.59?6.34 mg/L(x?s),and the value was 57.25?82.93 mg/L in the pancreatic cancer group,which was significantly higher than the normal value and that of the other malignant disease group(P

Objectives To compare the efficiency and clearance of single dose low molecular weight heparin(LMWH) as anticoagulant in hemodiafiltration and hemodialysis.Methods Twenty-two patients were enrolled in the study.A single injection of LMWH(Nadroparin calcium 7500ICUAXa) was given before hemodiafiltration and hemodialysis respectively.The anti-factor-Xa activity and the activated partial thromboplastin time(APTT) in plasma were assayed during the treatment,and the dialyzer coagulation was observed.The changes of urea and serum creatinine were measured before and after the treatment.Results The anti-factor-Xa activity of LMWH during hemodiafiltration was lower than that during hemodialysis.However,there was no significant difference in APTT between the two groups.Conclusions A single bolus injection of Nadroparin provides a simple and effective anticoagulation regimen for hemodiafiltration lasting up to four hours.

Object To optimize the process for the extraction of the original recipe used in the treatment of eczema to give a new ECZEMA SPRAY dosage form Methods The extraction process was studied by orthogonal experimental design as guided by determining the content of paeonol and baicalin in the extract Results The optimal extraction process was to reflux the original recipe with 80% ethanol twice at a bath temperature of about 90 ℃ for 1 5 and 1 0 h respectively The amount of ethanol used for each extraction was 10 and 8 times of the original recipe respectively Conclusion The above extraction process gave the most rational and satisfactory results

This paper proposed a rehabilitation training system with electromyography (sEMG) feedback for stroke patients based on ARM embedded system and LabVIEW. The system can achieve real-time acquisition, processing and dualview of multi-channel sEMGs and compute related sEMG parameters including iEMG, RMS, MPF and co-contraction ratio. The system was detected by clinical experiments and related inspection department. The result showed that the system is functional, interactive and in accordance with the relevant standards for medical devices so that it can fully satisfy the clinical demands. In addition, the system can help doctors to master the training state of the patient more effectively in a real-time and quantitative way that is direct to improve the training programs of stroke patients.

A Review: A concept of tissue adaptation to hypoxia (i. e. hypoxic preconditioning) was developed and its corresponding animal models were reproduced in 1966s. The methods of model reproduction in rat, rabbit, and mouse in particular and the main results are briefly introduced in this review. The tolerance to hypoxia of preconditioned animals is significantly increased. Regular changes in animals' behavior, neurophysiology, respiratory and circulatory physiology, neuron morphology in vivo and function of brain and spinal cord in vitro are briefly demonstrated. The protective effects in vivo and in vitro of homogenate extract taken from the brain of preconditioned animals, neurochemicals and molecular neurobiological alterations are briefly presented. The essence and significance of tissue adaptation to hypoxia/hypoxic preconditioning are discussed in the review in terms of evolution and practical implication.

Objective To explore the pathological changes of the livers from hepatic failure (HF)patients and its association with clinical disease stages.Methods Thirty-nine patients with liver failure caused by HBV infections were investigated,and none accompanied with hepatocellular carci- noma.The sections of tissue were taken from the liver after liver transplantation and stained with he- matoxylin eosin(H&E)or RT(reticular fiber)staining.The pathological features were analyzed and compared between the clinical and pathological diagnosis.Results 1.The range and the grade of the pathological changes were all well-proportioned in the whole liver but quite asymmetrical in the same spicemen.2.4 cases with clinical diagnosis of cirrhosis(active stage)were in accordance with the pathological diagnosis.Only 17 in 35cases can be pathologically diagnosed as chronic severe hepatitis (SH),while the other 18 cases were pathologically diagnosed as cirrhosis(active stage).Conclu- sion There were a great inconsistency between the clinical and pathological diagnosis.
