"Three-multi" overall evaluation system on the teaching effect of Microbiology experiment,which consisted of multi-aspect,multi-angle and multi-level,was discussed in this paper. The evaluation system showed a remarkable effect in stimulating the leaning interests of students especially.

Objective To observe the characteristics of cognitive impairment in patients with primary hypothyroidism.Methods A total of 90 primary hypothyroidism patients untreated with thyroid hormone were selected.All the 90 patients were divided into subclinical hypothyroidism group,mild or moderate hypothyroidism group and serious hypothyroidism group,and 30 patients in each group.The other 30 healthy volunteers were selected as controls.Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were used for the testing their orientation,immediate memory,attention and calculation,delayed recalling,linguistic competence,visual space and execution,naming ability and abstracting power.One-way analysis of variance was performed to determine significant differences among four groups.Results The MMSE scores in subclinical hypothyroidism group,mild or moderate hypothyroidism group and serious hypothyroidism group((27.53 ± 2.16),(26.90±1.88) and (24.80 ± 2.10) respectively) were lower than those of the control (28.23 ± 1.33).The MoCA scores of the above hypothyroidism groups ((23.57 ± 3.33),(2 1.60 ± 2.81) and (20.53 ± 3.03) respectively) were also lower than that of the control (26.63 ± 2.31) (P ＜ 0.05).Except for orientation and immediate memory,statistical significances of the other cognitive function were existed between hypothyroidism groups and the healthy controls (P＜ 0.05).With the increase in severity of hypothyroidism,the abnormality of attention,calculation,linguistic competence,visual space and executive ability,naming ability and abstracting power were appearing gradually in hypothyroidism groups (P ＜ 0.05),and the scores were low(P＜ 0.05).Conclusion Defects of attention and calculation,delayed recalling,linguistic competence,visual space and execution,naming ability and abstracting power are existed in primary hypothyroidism patients.

Based on the research of text (Ⅰ) which determined the fermentation medium, the fermentation condition of CNY086 including temperature, volume, inoculum and inoculum age had been studied by single factor and orthogonal experiment. The optimum temperature, liquid volume, inoculum and seed age were 15?C, 250 mL/500 mL, 15%, 10 h. Under the conditions above mentioned, enzyme activity reached 104.36 U/mL in 5 L fermentor.

21 cold-active strains which produced cold-active cellulase were isolated from Bohai Bay. One of the strains CNY01 was a kind of Trichoderma viride and its cellulase activity was 67.30 U/mL. Through UV and DES mutation, the strain CNY086 was bred and its cellulase activity was 92.17 U/mL. The strain CNY086 had stable ability to produce cellulase. Through orthogonal experiment, the optimal condition of the fermentation medium had been tested. The suitable medium was that straw power 1.20%, bran 0.70%, (NH4)2SO4 0.50%, KH2PO4 0.55%, in this condition the cellulase activity came to 108.55 U/mL.

Objective To evaluate the efficacy of argon surper-cryosurgery system (ASSS) in the treatment of huge hepatic multi-nidus carcinoma at advanced stage in cases of which conventional surgery is impossible. Methods Twenty-two patients with huge hepatic multi-nidus carcinoma at advanced stage, incurable with conventional surgery, were treated by ASSS in combination with entire or reduced-size excision. In terms of combined treatment, 1 patient received reduced-size operation and portal vein chemotherapeutic pump, 2 with entire excision and portal vein chemotherapeutic pump, 1 with entire excision and liver artery chemotherapeutic pump, 3 with only liver artery chemotherapeutic pump, and 6 with portal vein chemotherapeutic pump. Nine patients were simply treated by ASSS. Results The surgical procedures went smoothly in all cases and the complications, such as bleeding at the puncture aperturae, thorax effusion, bile leakage and liver cataphora, were successfully managed. The follow-up study was performed and all patients surived with the longest survival of 11 months up till now. Conclusions ASSS offers a new treatment method for huge hepatic multi-nidus carcinoma at advanced stage, but the indications must be carefully observed, and the surgical skills and prevention of complication are of great importance.

The fermentation conditions of high 1.3 -propanediol-producing strain E. aero-N-56 were determined in this Paper. The optimum conditions of producing 1.3-PD were: initial pH 7.0, temperature 30℃, culture time 48 h, inoculum size 9% . Under the optimum conditions: the 1.3-PD productivity reached up to 23.68 g/L?d; the 1,3-PD yield of E. aero-N-56 up to 47.36 g/L in 30 L fermentor.
