A new teaching model for food fermentation technology education is proposed in this paper,aiming at improving some of the drawbacks of the traditional teaching method. Some novel approaches,such as summarization,comparison,discussion,as well as bi-lingual lecturing and multi-media assisted teaching,are introduced to inspire students’ passion for learning. Meanwhile,arranging students as dedicated class speaker and organizing students to participate in the exploring experiments also reflect the technology major education characteristics of normal university.

Through the exertion of the PBL in the teaching of the medical college,the teachers exert the effect in bringing forward questions,grouping,discussion and competition.After the practice of PBL,some new methods have been put forward.

Objective: To investigate effects of different frash gas flow of oxygen ventila-tion on emergence time and delirium undergoing Enflurane general anesthesia. Methods: Forty- eight patients, ASA Ⅰ- Ⅱ, aged 33- 68yr, mean 50.5yr, underwent elective abdominal op-eration were randomly divided into three groups according to the different frash gas flow at the end of operation: GroupⅠ, the flow of oxygen maintained at 2 L/min, GroupⅡ 4 L/min, GroupⅢ 10 L/min. Anesthesia was induced with intravenous midazolam 0.08- 0.1mg/kg, etomidate 15- 20mg,fentanyl 3- 4 ?g/kg, pipecuronium 0.08- 0.1mg/kg and maintained with Enflurane(1.5- 2.0vol%), supplemented with intermittent iv pipecuronium and fentanyl. The concentration of Enflurane was monitored continuous which involved Fi, Fa and Fao, originated from inspiration, expiration and the moment expiration when stopped inhalation. Accounted Fao and after this detailed every one minute Fa until the patients recovery and calculated Fa/Fao ratio. Emergence time was recorded. Mini- Mental State Examination (MMSE) was performed before anesthesia and after surgery. Results: Fa/Fao ratio in GroupⅠ was significantly defferent from GroupⅡ and Ⅲ. MMSE scores in GroupⅠwere higher compare with GroupⅡand Ⅲ after surgery. Emergence time was no signif-icantly difference among three groups. Conclusion : The frash gas low flow of oxygen ventila-tion might reduce the incidence of delirium,but does not influnce the time of emergence from general anesthesia.

ObjectiveTo explore the application value and techniques of vaginal hysterectomy of non-prolapsed uterus lesion in primary hospital. Methods140 cases who suffered from uterine fibroid without adhesion,glandular fibroids,functional bleeding without uterine prolapse and malignant disease were selected and divided into observation group(80 cases with vaginal hysterectomy)and control group(60 cases with routine abdominal hysterectomy).Then the clinical treatment effect was analyzed. ResultsCompared with control group,peri-operative bleeding (150 ±23)ml vs(243 ±41)ml,operation time(65 ± 14.0)min vs(90 ± 27.0)min,body temperature recovery time (3 ±0.5)d vs(4 ±0.8)d,anus exhaust time(14 ± 1.8)h vs(26 ±2.7)h,the length of time(5 ±0.8)d vs(11 ±2.9)d in observation group were all reduced,differences were significant(all P＜0.01)and no case was transferred to opening appendectomy. ConclusionFor these disease including uterine fibroids with no adhesion,glandular fibroid uterine bleeding,the vaginal hysterectomy was safe and feasible,and had the advantage of smaller trauma,less bleeding,shorter hospitalization time,faster recovery etc.It was worthy to be popularized in primary hospital.

Objective To explore the influence of Lipo PGE1 on endothelin (ET-1) and interleukin (IL-6) in exhaled breath condensate(EBC) of patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension(PH) and its clinical significance.Methods A total of 40 cases of patients with COPD and PH were randomly divided into thecontrol group and the treatment group,20 cases in each group.The control group was administered with the conventional treatments such as anti-infection,bronchodilator,antiasthma,expectorant and oxygen therapy;the treatment group was administered with Lipo PGE1 (10 μg/d,iv,for 10 days) besides the conventional treatments.ET-1 and IL-6 in EBC,pulmonary artery systolic pressure(PASP),arterial blood PaO2 and PaCO2,lung function FEV1/FVC,FEV1%pred in both groups were assayedbefore and after the treatment.Results There were no statistical difference between the two groups in the ET-1 and IL-6 in EBC,PASP,arterial blood PaO2 and PaCO2,FEV1/FVC,FEV1% pred before the treatment.After the treatment,the ET-1,IL-6 in EBC,PASP and arterial blood PaCO2 of the treatment group were lower than thoseof the control group (P<0.05);the arterial blood PaO2,FEV1/FVC,FEV1% pred of the treatment group were higher than those of the control group (P<0.05);The levels of ET-1 and IL-6 in EBC wereboth positivelycorrelated with PASP in the two groups.Conclusion Lipo PGE1 can reduce the levels of ET-1 and IL-6 in EBC of patients with COPD and PH.ET-1 and IL-6 may become a curative effect judgment index of COPD and PH,which has a certain clinical significance.

Impaired glucose tolerance is the prediabetic state of diabetes mellitus,and its main manifestation is postprandial hyperglycemia.Studies in recent years have suggested that the large vascular disease of the impaired glucose tolerance state is similar to diabetes mellitus.The relationship between impaired glucose tolerance and atherosclerotic disease is increasingly receiving attention.This article reviews the relationship between both of them.

This paper introduces the generating principle of energy correction table for digital gamma camera and elaborates a method for real-time energy correction. According to the position information of the collected events, correction cells are determined. With the correction value in four adjacent correction cells, coefficient of energy correction is worked out through bilinear interpolation. Finally, real-time energy correction for the collected events is achieved through software programming.

Objective To evaluate the application of capsaicin to improve bladder stability after suprapubic prostatectomy for BPH. Methods 40 patients with BPH underwent suprapubic prostatectomy under epidural anesthesia were randomly divided into A?B?C and D groups (n=10 in each group).Capsaicin of 1 mmol/L was instilled into the bladder preoperatively for 30 minutes in group B and group D had 10 ml of 1 mmol/L capsaicin given epidurally.Group A and Group C received saline only. Results The bladder instability was lessened.The time of bladder perfusion clearance,indwelling catheter delivery,duration of cystospasm and number of postoperative cystospasm cases in group B and D reduced significantly as compared with group A and C.The Pdet and volume were improved significantly,the Qmax and residual urine were also improved. Conclusions The intravesical and epidural capsaicin delivery helps to prevent detrusor instability and reduces the pain caused by postoperative cystospasm.It also improves the bladder function deteriorated by BPH.

The dental abrasive testing machine applies a V-like swing arm to driving the wearing part to move along the slope back and forth, which is connected with an eccentric wheel fixed on the crankshaft of the gear motor through a connecting rod. Various abraders can be held on the wearing part with an adjustable wearing pressure between 10 and 500g loaded on the specimen. During wearing, both abrader and specimen are immersed in the wearing medium. Before and after the test, the specimen is weighed and its wearing surface is recorded by a profilometer, then the weight loss and volume loss can be calculated.
