The causes of "Plateau Phenomenon"in College English learning are analyzed on the basis of the investigation and the study of the Learning Curve.Some solutions to cope with the stagnation are also suggested.It's worth attention that Learning Strategy can be a vital factor to overcome the"Plateau Phenomenon."

In recent years,a variety of new therapeutic drugs have shown a certain effect on T-cell non-Hodgkin lymphoma(T-NHL) ,such as nucleoside analogues,BCR / ABL tyrosine kinase inhibitor,L-asparaginase,protease inhibitor,cytokines,and monoclonal antibodies.

The antifungal susceptibility testing is playing important roles which include: understanding the susceptibility of the fungus to the antifungal agents and monitoring the resistance during therapy.Our purpose in this editorial is to tell the readers the proper application of MIC detection;to emphasize the clinical relevance of the in vitro susceptibility,and especially,to introduce the recent clinical study data which give the detailed explanation on the clinical relevance of MIC.

The introduction of lipid-formula Amphotericin B,Voriconazole,and Echinocandins,including Caspofungin and Micafungin,reflect the trend that the antifungal drugs are being developed along to a direction with high effect,broad spectrum,and low toxicity.These drugs undoubtedly provide novel useful approaches to the treatment of invasive fungal infections.Compared to the traditional antifungal drug,such as amphotericin B and Fluconazole,these drugs have the character of good effect and low adverse effect,which will be very important to prophylaxis and treatment for systemic fungal infections.The information concerning for these issues is being reviewed in this paper.

Objective To evaluate the value of carcino embryonic antigen(CEA),carbohydrate antigen 19,cytokeratin(CYFRA21-1),squamous cell cancer antigen(SCC) and neuron specific enolase(NSE) for the evaluation of chemotherapy response in the patients with advanced lung cancer.Methods One hundred and thirty-six patients with advanced lung cancer(lung cancer group) and 40 patients with lung benign disease(control group) were collected.The lung cancer group was treated with at least two courses of chemotherapy.The CYFRA21-1,SCC,CEA and NSE levels before chemotherapy were compared among the lung cancer group,control group and the patients with different pathological types.The above mentioned tumor markers levels before and after chemotherapy were compared among the patients with different curative effects in the lung cancer group.Results The levels of serum NSE,CYFRA21-1,CEA and SCC before treatment in the lung cancer group were higher than those in the control group(P<0.01);the serum CEA level of the squamous carcinoma group was higher than that of the adenocarcinoma group and the small cell carcinoma group(P<0.01),and the serum NSE level of the small cell carcinoma group was higher than that of the adenocarcinoma and squamous cell carcinoma group(P<0.01),and the levels of CYFRA21-1 and SCC of the squamouscarcinoma group were higher than those of the adenocarcinoma and small cell groups(P<0.01).The serum CEA level of patial remission(PR) patients in adenocarcinoma group was significantly decreased(P<0.01),the serum SCC level of PR patients in the squamous cell carcinoma group was significantly decreased(P<0.05),and the serum NSE level of PR patients in small cell carcinoma group was significantly decreased after chemotherapy(P<0.01).The difference of serum NSE,CYFRA21-1 and SCC after chemotherapy in stnble and prosgoressive patients of various groups were not statistically significant(P>0.05).Conclusion CEA,CYFRA21-1,SCC and NSE can be used as the effective evaluation indexes of chemotherapy in lung adenocarcinoma,lung squamous cell carcinoma and small cell carcinoma,but which has little significance in the patients without effect of chemotherapy.

Objective:To evaluate the role of beta-2-microglobulin in the development of eqidemic encephalitis B.Methods:Forty-eight cases of epidemic encephalitis B children were divided into medium and severe types and beta-2-microglobulin was measured in their serum and cerebrospinal fluid(CSF) by radio-immunoassay(RIA).Twelve cases of control study was taken simultaneously.Results:At initial period,the serum and CSF concentrations of beta-2-microglobulin in forty-eight cases of epidemic encephalitis B patients were higher than that of the controls( P

· AIM: To study the expression of basic fibroblast growth factor (bFGF) receptor protein in human lens epithelial cells (HLECs). METHODS: Immunohistochemistry was used to detect the level of bFGF receptor protein and image analysis was adopted to perform the relative quantitative analysis on it. · RESULTS: There was bFGF receptor protein in HLECs accordingl to both qualitative and quantitative analysis. · CONCLUSION: bFGF receptor protein exists in HLECs and it is the material foundation for bFGF to improve the proliferation of HLECs.

BACKGROUND: Both animal experiments and clinical practice have confirmed that mild or moderate hypothermia is effective in reducing secondary brain injury, but its effect on homeostasis is not very clear.OBJECTIVE: To investigate the effect of a combined therapy of mild hypothermia and hibernation on the homeostasis of patients with severe brain injury.DESIGN: A randomized controlled study.SETTING: Neurosurgical Institute of Beijing; Neurosurgical Department of the First Clinical Medical College Affiliated to Harbin Medical University;and Neurological Department of the Second Clinical Medical College Affiliated to Harbin Medical University.PARTICIPANTS: The study was conducted at the Department of Neurosurgery, the First Affiliated Hospital of Harbin Medical University, from June to December 2002. Totally 24 patients (aged 35-60 years) with severe cerebral hemorrhage or brain injury were randomly divided into combined therapy group and normothermia group. Their Glasgow Coma Scale scores ranged from 3 to 8. The subjects signed the informed consent.METHODS: Within 10 hours of their injury, patients in hypothermia and hibernation combination group were given half dosage of No. 1 hibernation cocktail (chlorpromazine 25 mg, pethidine hydrochloride 50 mg, and promethazine 25 mg), and were cooled by cooling blankets to make their body temperature dropped to 32-34 ℃ (rectal temperature). Their temperature was kept within this range for 5 days, at 35 ℃ for 24 hours, and then was slowly increased to their normal level. The body temperature of patients in normothermia group was maintained at 37-38 ℃. The mean arterial pressure and heart rate of all patients were measured continuously by HP monitor. On the 3"d and 7th days of hospitalization, intracranial pressure and creatine phosphate kinase were measured via lumbar puncture.Femoral artery puncture was performed to check the partial pressure of arterial O2 and CO2. Platelets count and blood electrolytes K+ and Na+ concentration of each patient were measured, too. On the 7th day Glasgow Outcome Scale scores of each patient and mortality of each group were recorded.activity of creatine phosphokinase, platelets count, blood K+ and Na+ conand CO2 of patients in combined therapy group on the 3rd and 7th days of hospitalization.intracranial pressure, creatine phosphokinase and platelets count: The decreased values of intracranial pressure, creatine phosphokinase and platelet number in combined therapy group were all significantly higher than those in normothermia group [(104.09±54.90), (58.75±25.33) mm H2O; (26.95±19.22), (10.17±7.18) μkat/L; (89.82±46.36)×109/L, (48.83±44.59)×109/L,the mean arterial pressure, blood electrolytes, and partial pressure of artewas significantly lower than that of normothermia group (25.0%, 66.6%,P ＜0.05).CONCLUSION: This combined therapy of hypothermia and hibernation can effectively decrease intracranial pressure and creatine phosphokinase,but has no significant effects on the mean arterial pressure, blood electrolytes concentration, and partial pressure of arterial O2 and CO2. It has the risk of disturbing the patients' hematopoiesis.
