A high active soybean isoflavone glucoside hydrolase-producing mould strain was isolated from spirit qu. Its optimal hydrolase-producing conditions were as follows: 2.5% wheat bran as carbon source, 1% NaNO3 as nitrogen source, initial pH7. 0, culture medium volume 40mL/250mL, inoculating quantity 8% , culture temperature 30℃, revolutions 160r/min and culture time 84h. The enzyme activity reached 82 U/mL. Cu2+ can inhibit Absidia sp. R strain from producing the hydrolase, the influence of other metal ions was not remarkable on it.

Objective To evaluate the effect of nitrous oxide(N2O) on the cuff pressure of ProSeal laryngeal mask airway(PLMA) in pediatric anesthesia. Methods Thirty-two pediatic patients were enrolled and divided into two groups randomly.PLMA cuffs were inflated with air(Group A) or 50% N2O/oxyen(Group N) to 20 mmHg as initial pressure.The intracuff pressure was monitored during anesthesia with 50% N2O in oxygen. Results Intracuff pressure increased to(40.6?9.3) mmHg in Group A and slightly decreased in Group N.Deflation volume in Group A was much more than that in Group N[(4.4?2.3) mL vs(2.6?1.0) mL,P

Objective To study the clinical significance of P - selection expression in children with viral encephalitis and the correlation between this expression and the cerebral infarction with critical viral encephalitis. Methods Flow cytometric was employed to detect the expression of P- selection on the surface of platelet membrane in 44 children with viral encephalitis(20 light patients and 24 critical patients) and 20 healthy control children. The area of the cerebral infarction was determined by computed tomographic scan in 20 patients with critical viral encephalitis. The correlation between the two variables was analyzed. Results The expressions of P - selection on the surface of platelet membrane on less than 5 days and on 2 weeks after the onset of viral encephalitis were significantly higher in critical patients than those in normal control children and light patients( P

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.

Objective To evaluate the curative effect of chemotherapy combined with radiotherapy for limited-stage small cell lung cancer(LD-SCLC).Methods 34 cases of patients with LD-SCLC were rand- mized into interdigitating chemoradiotherapy group and sequential chemoradiotherapy group.All patients re- ceived four to six cycles of alternating CE(C:carboplatin 300 mg/m~2 d_1;E:etoposide100 mg d_(1~5)and CAP(C: cyclophosphamide 600 mg/m~2 d_(1,8);A:adriamycin 40 mg/m~2 d_1;P:cisplatin 50 mg d_(3~5)chemotherapy,three weeks for a cycle.All patients also received thoracic radiotherapy with conventional fraction,2.0 Gy per frac- tion,five fractions per week.The total dose was 60 Gy.Results In interdigitating chemoradiotherapy group, CR was 64.7%,PR was 29.4%,NR was 5.9% and PD was 0 after chemo-radiation therapy.In sequential chemoradiotherapy group,CR was 23.5%,PR was 52.9%,NR was 23.5% and PD was 0 after chemothera- py,and CR was 58.8%,PR was 35.3%,NR was 5.9% and PD was 0 after radiotherapy.Conclusion The therapeutic effect of chemotherapy combined with radiotherapy for LD-SCLC was satisying.There was no sig- nificant difference in the effect between the two groups.
