It has been proved that erythropoietin has neuroprotective effect and therapeutic action on cerebral ischemia in vivo and in vitro. The mechanisms of these actions may be involved in anti-exitotoxicity of aminoglutaric acid, regulating the synthesis of nitric oxide, antioxidation, antiinflammatory, inhibiting neuron apoptosis, accelerating angiogenesis, neurogenesis, neurotrophy and others. In addition, exogenous erythropoietin can enter brain tissue through blood-brain barrier and exert neuroprotection. So it is indicated that erythropoietin can be expected to be a new drug to prevent and treat cerebral ischemia.

Macrofungi are rich in natural bioactive compounds so they have much medicinal value.Their immunomodulating and anticancer activity particularly attracts more attention.Based on the polysaccharides molecular structure and their relation to these activities,this paper discusses their mechanism of the immune responses and introduces the important instances of these polysaccharides along with their immunomodulating and/or anticancer activity isolated from putative medicinal mushrooms.

Objective To establish a method for the determination of phthalates in water by solid phase extraction-gas chromatography-mass spectrometry(SPE-GC-MS).Methods The water samples were extracted and enriched by solid phasse extraction,using 10%methanol-methyl tert-butyl ether as eluant,dimethylphthalate(DMP),diethylphthalate(DEP),dibutylphthalate (DBP)and diethylhexylphthalate(DEHP)were determined by gas chromatography-mass spectrometry with selected ion monitoring mode(SIM).Results The concentration had a good linear range in the range of 0.00~10.00?g/ml,the correlation coefficient was above 0.998.The detection limit of DMP,DEP,DBP and DEHP were 2.7,2.1,1.6 and 2.5 ng/L respectively,the average recovery rate and the RSD of the method were 78.0%～102.5%and 3.3%～7.8%respectively.Conclusion This method,with small amount of solvent,is simple,fast,accurate and is applicable to the determination of phthalates in water.

It was well known that the damage of skeletal muscle occurred and exercise performance declined after one prolonged eccentric exercise.But there were few studies on the adaptation to the continuous eccentric exercise in skeletal muscle.The purpose of this study was to investigate the effects of downhill running once(group B) and for one week(group C ) on α-actin gene expression of rat gastrocnemius muscle.Serum CK and LDH were determined, too.The results showed that the training had obvious effects on α-actin gene expression of rat gastrocnemius muscle in group B and C.In group B, serum CK and LDH recovered obviously 7 days after training, but not to the normal value.In group C, it recovered to the normal.These results suggest that the recovery of the damage after first training had been accelerated by the continuous eccentric exercise, the subjects gradually adapted to exercise.

Objective To study in patients characteristics of head CT and MRI of patients with brain stem injury at acute stage(＜7 days)and discuss the relationship of head MRI manifestations and prognosis so as to provide indicators for imaging diagnosis and prognostic evaluation.Methods The patients with brain stem injury from November 2007 to September 2008 were involved in the study.Cranial CT and MRI were performed at early stage after brain stem injury.The patients were followed up for six months to evaluate prognosis and life quality of the patients based on disable rating scale(DRS)and Barthal score.Results MRI could detect more brain stem injuries than CT.The patients with injury at different parts of brain stem showed a statistical difference in regard of prognosis.Conclusions At acute stage of brain stem injury,cranial MRI has higher detection rate and clearer display of the brain stem lesions compared with CT.MRI manifestations can not only help classification of the brain stem injury,but also cater basis for diagnosis and prognosis evaluation of patients with brain stem injury.

As a minimally invasive method of examination, magnetic resonance spectroscopy can provide information of brain metabolism and biochemistry, objectively reflect brain metabolite changes. Different manifestations were described in the diseases such as brain injury and brain tumor. As a result, magnetic resonance spectroscopy can be a helpful technology to give information of diagnosis and prognosis in neurosurgery for brain injury, brain tumor as well as brain abscess and epilepsy.

Objective Ethanol, acid and alkali were used in the traditional Bererine extracting which required quite a few extracting time and polluted the environment. Water instead of ethanol was used. Microwave irradiation was chosen as the extracting method. Methods The best parameters, microwave power, extracting time, solid-liquid ratio were got in the experiment. According to the orthogonal experimental design, the optimum extracting condition was determined. Results Microwave irradiation, compared with the traditional extracting techniques, was with short extracting time. Conclusion The method was practicable and the product possessed the virtue of high purity, safe quality and free pollution.

Objective To perform APACHEⅡand SOFA in assessmentof EICU patients with sepsis ,and analyze the risk factors. Methods A retrospective analysis from January 2014 to October 2015 in EICU of our hos-pital ,a total of 83 patients suffered from sepsis ,including sepsis group(30 cases)and septic shock(53 cases). PCT,PT,APTT,lactic acid,mechanical ventilation time and APACHE Ⅱ and SOFA score were collected, through the receiver-operating characteristic curve(ROC)index to predict the prognosis of patients with sepsis.Re-sults The mortality of the patients in the septic shock group,PT,APTT,APACHEⅡ,SOFA score,mechanical ventilation time and PCT were significantly higher than thosein the sepsis group(P<0.001). APTT,APACHEⅡ, SOFA score and mechanical ventilation time had significant difference (P ≤ 0.001) between survival and dead. The lactic acid level of the dead group was significantly higher than that in the survival group(P=0.038). The ar-ea under curve(AUC=0.806)of APACHEⅡscore was better than the SOFA score(AUC=0.765).The outcome of sepsis had correlation with APACHEⅡ,SOFA score,lactic acid,and mechanical ventilation time(P<0.05). Conclusion APACHE II and SOFA scores can accurately predict mortalityoutcome in emergency intensive care units patients with sepsis,especially the APACHEⅡscore.We can measure blood coagulation function,APACHEⅡ,SOFA score,PCT,lactic acid and mechanical ventilation time to assess the severity of patients with sepsis.

OBJECTIVE: To provide reference for the application of automatic tablet packing machine in the inpatients dispensary.METHODS: The working principle and flow,the main structure and function of the automatic tablet packing machine used in our hospital were introduced,and its application value was evaluated and the problems remained to be dealt with were pointed out.RESULTS: The automatic tablet packing machine had the advantages of high accuracy and efficiency,and reduced working intensity,however,the costs for the packaging and consumables,and the low drug quality were the problems remained to be solved.CONCLUSIONS: Automatic tablet packing machine is suitable for the dispensing of oral single dose of tablets for inpatient patients,and it helps to improve the work quality and the service level in the dispensary for inpatients.
