Objective 18 patients of brain stem tumors in results were analyze retrospective by Stereotactic Conformal Radiotherapy.Methods From March 2000～March 2005.18 patients with brain stem tumors were treated by SCRT.The patients age were 6～67 years old,midian age were 28 years.The dose was 45～60Gy/5～7week.Results The symptoms had been improved in 15/18 cases at the end of the radiotherapy.The 1-3 and 5 year survival rates were 57.6%,42.6% and 30.4%.The complication occurrence rate was 13.13%.Conclusions The Stereotactic Conformal Radiotherapy is a main therapy mean to brain stem tumors.That can improved survival rates and life quality of the patients with brain stem tumors.

OBJECTIVE: To analyze the oil content and fatty acid constituents of Fructus Quisqualis.METHODS: The fatty oil of Fructus Quisqualis was extracted by supercritical fluid extraction (SFE) .The content of oil and compositions of fatty acid were determined by gravimetric analysis and GC - MS respectively .RESULTS:The oil content of Fructus Quisqualis was 27.70% .Among the fatty acids, oleic acid, linoleic acid and palmitic acid were dominant.The unsaturated fatty acids accounted for 63.93% of the total fatty acids, and the major saturated fatty acid was palmitic acid .CONCLUSION: The oil of Fruclus Quisqualis is of highquality,and the analytic results provide scientific basis for exploitation and utilisation of the oil of Fructus Quisqualis.

Objective To observe the clinical efficacy of acupuncture in treating functional dyspepsia. Method Sixty-eight patients with functional dyspepsia were randomized into an acupuncture group and a control group. The acupuncture group was intervened by matrix needling, once a day, 8 d as a course, with a 2-day interval between two courses, for successive 4 weeks. The control group was prescribed with Motilium at 10 mg, 3 times a day, for successive 4 weeks. Result The total effective rate was 91.4% in the acupuncture group versus 87.9% in the control group, and the difference was statistically insignificant (P>0.05); there was a significant difference in abdominal pain score between the two groups (P<0.05), indicating that the acupuncture group should be superior to the control in releasing abdominal pain. Conclusion The overall efficacies in treating functional dyspepsia are equivalent between the acupuncture group and control group, but the acupuncture group is better than the control in releasing pain. Therefore, compared to medicine, acupuncture has advantage in treating functional dyspepsia.

ObjectiveTo observe the infection of continuous aspiration of subglottic secretion(CASS) for patients with ventilator associated pneumonia (VAP).MethodsOne hundred and fifty VAPpatients under mechanical ventilation whose basical information were recorded were divided into two groupsby random digits table method:control group(70 cases) and CASS group(80 cases).Conventional VAPprevention was taken in control group and CASS group,while CASS therapy was added to CASS group.ResultsSex,age,acute physiology and chronic health evaluation Ⅱ score,recent antibiotics usage,airpressure,time in ICU,hospital stay and mortality rate of two groups had no statistical significance(P ＞0.05 ).The time of ventilator treatment of CASS group was obviously shorter than that of control group [ (5.2 ±1.4) d vs.(7.8 ± 1.2) d,P =0.02 ],and VAP incidence was lower than that of control group [ 22.5％ (18/80)vs.32.9％(23/70),P =0.04 ].ConclusionCASS could reduce the incidence of VAP and short the time ofventilator treatment.

Angiotensin converting enzyme 2 (ACE2) is a new member of renin-angiotensin system found recently. It counterbalances the effects of angiotensin converting enzyme (ACE), hydrolyzes angiotensin Ⅱ to generate angiotensin-(1-7) and hydrolyzes angiotensin Ⅰ to produce angiotensin-(1-9). Angiotensin-(1-9) can be hydrolyzed by ACE to form angiotensin-(1-7), and angiotensin-(1-7) counteracts the effects of angiotensin Ⅱ in many aspects. Bradykinin or atrial natriuretic factor or substance P are not the substrates of ACE2, and ACE2 hydrolyzes the metabolites of bradykinin such as des-Arg~9-BK and des-Arg~(10)-kallidin, and also the dynorphin A, one of the opium peptides. ACE2 is not inhibited by angiotensin-converting enzyme inhibitor (ACEI). Recent studies demonstrate that ACE2 is a functional receptor of SARS coronavirus. To elucidate the mechanisms of cardiovascular diseases and other disease such as SARS, further investigations in ACE2 are needed.

OBJECTIVE:To establish a simple method of the magnesium measurement i n the sodium-magnesium fructose-1,6-diphosphate METHODS:Ion exchange-EDTA titration was adopted RESULTS:The RSDs of both the precision and accuracy wer e less than 0 51% by the method(n=6) CONCLUSION:This method is convenient ,and the results are accurate It can satisfy the determination of sodium-magn esium fructose-1,6-diphosphates

Objective To observe the pathogens and drug-resistance of ventilator-associated pneumonia (VAP) patients in emergency intensive care unit (EICU) for rational antibiotic therapy and the prevention of VAP. Method The sputum culture results and drug-resistance of pathogens of VAP patients in EICU from 2007 to 2009 were collected. Results One hundred and two mechanical ventilation patients were selected. VAP was occurred in 70 patients (68.6%). One hundred and fifty-seven pathogens had been examined,including 92 Gram-negative bacilli (58.6%),35 Gram-positive cocci (22.3%) and 30 fungus (19.1%). Pseudomonas aeruginosa and meticillin-resistant-staphylococcus aureus was 22 strains (14.0%)respectively, stenotrop homonas maltophilia was 21 strains (13.4%) and acinetobacter baumanii was 17 strains (10.8%). Fifty-nine patients (84.3%) had suffered from multiple pathogen infection, with 31 cases having 2 pathogens and 28 cases having 3 pathogens. Conclusions Pseudomonas aeruginosaa,methicillinresistant staphylococcus, stenotrophomonas maltophilia and acinetobacter baumanii are main pathogens of VAP in EICU patients,and candida albicans is still the main pathogens in fungal infection. The rate of multiple pathogen infection is very high, and the problem of drug-resistance is very severe.

Objective To discuss the distribution of irregular antibodies of red blood cells and its clinical significance .Methods Micro-column gel anti-globulin technique was used to screen and identify the irregular antibodies in 6 352 patients .Results In 6 352 patients ,there were 62 cases(27 males ,35 females)having positive results in irregular antibody detection ,and the positive rate was 0 .97% .There were 54 cases having transfusion history and/or pregnancy history ,including 43 cases of irregular antibodies of Rh system(containing 34 cases of anti-E antibody) ,7 cases of MNSS system ,2 cases of Lewis system ,2 cases of Kidd system ,2 cases of P system ,1 cases of Diego system ,and 5 cases with non-specificity .All of the patients whose irregular antibodies of Rh blood group system were positive had transfusion history and/or pregnancy history .Conclusion Most of the patients with irregular anti-body positive are females ,who mostly have transfusion history and/or pregnancy history ,and the irregular antibodies of Rh system are the most common .

Objective To investigate the therapeutic effects of recombinant human interleukin-11 (rhIL-11) on the vaginal epithelium mitosis of estrone periodical mice and the exprssion of PCNA.Methods The vaginal epithelium mitosis of estrone periodical mice was used as the epidermis hyperplasia model, rhIL-11 action in regulating the epidermis hyperplasia was observed and the expression of PCNA was detected by immunohistochemistry.Results The rhIL-11 significantly inhibited the mitosis of mouse vaginal epithelium, decreased the expression of PCNA ( P <0.01).Conclusion The rhIL-11 has good efficacy in treating the epidermis hyperplasia of psoriasis by inhibiting the mitosis of epithelium and decreasing the expression of PCNA.

OBJECTIVE To analyze the risk factors of respiratory tract infection by Stenotrophomonas maltophilia and its resistance to common antibiotics so as to guide clinical prevention and treatment.METHODS Thirty two patients of respiratory tract infection by S.maltophilia were examined.RESULTS Among them,the ratio of susceptivity of S.maltophilia to compound sulfamethoxazole was 87.5%,to levofloxacin was 78.1%,and to ticarcillin/clavulanic acid was 81.2%,but the ratio of resistance of S.maltophilia to imipenem was 100.0%,and it was also high to aminoglycosides and cephalosporins.CONCLUSIONS The old age,serious underlying diseases,many kinds of antibiotics used,infection in hospital and the use of glucocorticoids are the main risk factors of the respiratory tract infection by multiresistant S.maltophilia.
