This paper discussed the differences in teaching arrangement,material construction,teaching pattern, and teaching methods been used in medical microbiology teaching between China and the United State.

The dynamic level of immunosuppressants such as alpha-fetoprotein(α-FP), gestation associated protein, progesterone, estradiol, chorionic gonadotropin, etc. of peripheral sera and the regulatory mechanism of cellular immunity in the peripartum stages in sows were determined by advanced radioimmunoassay (RIA) and immunochemistry methods in this study. The effects on lymphocyte cultivated in vitro by the immunosuppressants mentioned above were tested by cell culture technology, respectively. The results were as follows: (1) α-FP: The level of α-FP of peripheral sera in the stage of ante-parturition was slightly higher than that of post-parturition in sows, but it didn't show statistical difference. The concentration of α-FP of peripheral sera in conceptus sows had no obvious effect on lymphocyte cultivated in vitro, and it indicated that α-FP was not the major immunosuppressant in the pregnancy of sows. However, the α-FP, whose concentration was equal to that of amniotic fluid, had obvious inhibition on lymphocyte cultivated in vitro. (2) Gestation associated protein: The level of gestation associated protein was maintained highly (100-162 mg/L) in peripheral sera and amniotic fluid in the stage of ante-parturition in sows, then descended gradually after parturition and disappeared step by step 5-10 d after parturition. The gestation associated protein, whose concentration were equal to that of peripheral sera and amniotic fluid, were added to lymphocyte culture in vitro, and the effect on lymphocyte activity was not observed yet. This showed that gestation associated protein was not the major immunosuppressant in the peripartum stage in sows. (3) Estradiol and progesterone: Estradiol or progesterone at the level of sera in pregnant sows, could lower the rate of lymphocyte transformation and the level of cellular immunity. (4) Chorionic gonadotropin: The level of chorionic gonadotropin of peripheral sera in the stage of ante-parturition was slightly higher than that of post-parturition in sows, but it didn't have statistical difference. The chorionic gonadotropin, whose concentration was equal to that of sera, was not yet observed obvious effect on lymphocyte cultivated in vitro. (5) Added the five above-mentioned immunosuppressants to lymphocyte culture in vitro, whose concentration were equal to those of sera in pregnant sows, they could drop the rate of lymphocyte resette formation and lymphocyte transformation, lower the level of cellular immunity and reduce the concentration of IL-2 which synthesized and secreted by lymphocyte in culture remarkably. Their inhibitory intensity of cellular immunity was evidently higher than that of any single immunosuppressant.

PBL is a modern model of classroom teaching. We have introduced it into the teaching of Microbiology. As a result, the students’ learning abilities have been raised to a higher level, and their learning autonomy and achievement have been improved. The combination of PBL method with traditional teaching methods achieved a good effect.

Objective To assess the efficacy and safety of paroxetine for epileptic patients following depression. Methods 156 epileptic patients were recruited. Patient Health Questionnaire 9-item Depression scale (PHQ-9) then the Hamilton Scale for Depression (HAMD)were the assessment tools. 31 patients, whose score of PHQ-9 more than 15 and HAMD more than 20 were selected. The monthly seizure frequency and depression severity were investigated before and 12 weeks after treatment with paroxetine, 20 mg/d. The side effects of paroxetine were also observed. Results 29 patients completed the observation. The total scores of the HAMD decreased 12 weeks after treatment (P<0.05). Dizziness was the most common adverse event during the first month of treatment. No seizure worsening was observed. Monthly seizure frequency did not change significantly. Conclusion Paroxetine is a safe and effective antidepressant for epileptic patients following depression.

Objective To discuss the method,safety and effect of malignant pancreas tumor treated by CT guided percutaneous embedding of~(125)I. Methods 32 cases of malignant pancreas tumor with CT scan and contrast enhancement were retrospectively analysed.All the cases had been confirmed pathologically be- fore CT guided therapy.The number of~(125)I particle was 12～46,The distance between particles was 0.～1.2 cm. The number of puncture point was 1～2.The number of puncture direction was 2-5 times.Results Regarding 32 cases for 1 month,the size of the tumor reduced in 11 cases,no change in 20 cases,and increased in 1 case.As for 31 cases for 2 months,the size reduced in 16 cases,no change in 13 cases,and enlarged in 3 cases.Regarding 30 cases for 3 months,the size reduced in 18 cases,no change in 11 cases,and increased in 3 cases. Regarding 28 cases for 6 months, he size reduced in 10 cases, no change in 5 cases, and in- creased in 13 cases.Regarding 22 cases for 1 year,12 cases had been done the second therapy,the size of the tumor reduced in 16 cases,no change in 3 cases,and increased in 3 cases.Conclusion The size of pancreas tumors were reduced obviously,the symptoms were relieved after the treatment.The method turned out to be safe and accurate.

Objective To investigate the relationship between the levels of fractional exhaled NO and airway inflammation cells in cough variant asthma(CVA)and the effect of inhaled corticoids .Methods CVA patients were treated with Budesonide and Formoterol Fumarate Powder for Inhalation for 6 months .Before and after treatment ,the provocative concentration of methacholine causing a 20% fall in forced expiratory volume in one second(PC20 FEV1 )was tested ,and the levels of fractional exhaled No ,and eo‐sinophil in induced sputum were examined .Results The levels of FeNO ,the percentage of eosinophil in induced sputum were sig‐nificantly higher than control healthy subjects ,and all decreased significantly after treated with ICS/LABA ,together with elevated PC20 FEV1 .The levels of FeNO were significantly correlated with the percentage of eosinophil in induced sputum ,and also negative‐ly correlated to PC20 FEV1 .Conclusion The levels of FeNO in CVA patients were significantly higher than control healthy sub‐jects ,and correlated with the inflammation of airway ,so FeNO may be used as a biomarker to determine the control level of airway inflammation in CVA patients .

Objective To explore the effects of early glucocorticoids (GC) therapy on the outcome of patients with acute respiratory distress syndrome (ARDS). Methods The clinical data of all ARDS patients admitted from January 2008 to December 2011 in Chengdu Military General Hospital of Chinese PLA were retrospectively analyzed. The adult patients whose diagnosis was in accord to the Berlin ARDS diagnostic criteria published in 2012 were enrolled, and based on whether using glucocorticoid or not, they were divided into GC group and non-GC group. All the patients in GC group received low dosage of intravenous GC within 48 hours after the onset of ARDS, including different kinds of GC, methylprednisolone, dexamethasone and hydrocortisone (hydrocortisone dosage < 5 mg·kg-1·d-1, the dosage of former two kinds of GC being converted to that of hydrocortisone), and the therapeutic course of the two groups was 7 to 21 days. The patients in non-GC group received no GC therapy after the occurrence of ARDS. The duration of mechanical ventilation, the length of intensive care unit (ICU) stay and totally in hospital, medical cost and 28-day survival rate were compared between the two groups. Results One hundred and seventeen patients with ARDS were collected, including 56 cases (47.86%) in GC group and 61 cases (52.14%) in non-GC group. The duration of mechanical ventilation in GC group was significantly shorter than that in non-GC group [days:0 (0, 2.50) vs. 2.00 (0, 2.50), Z=2.015, P=0.044]. The 28-day survival rate in GC group was significantly higher than that in non-GC group [71.43%(40/56) vs. 50.82%(31/61),χ2=5.198, P=0.023]. There were no significant differences in the length of ICU stay [days:7.50 (2.00, 11.00) vs. 4.00 (1.00, 9.00), Z=1.879, P=0.060] and stay totally in hospital [days:16.00 (10.00, 27.75) vs. 15.00 (7.00, 28.00), Z=0.592, P=0.552] between GC group and non-GC group. However, the medical cost in non-GC group was significant lower than that in GC group [10 thousand Chinese yuan:3.15 (1.51, 5.78) vs. 4.39 (1.66, 10.88), Z=2.204, P=0.028]. Conclusion The early GC therapy may improve the outcome of patients with ARDS, especially beneficial to the 28-day survival rate.

Objective To evaluate the effect of the setup error on the dosimetric verification for the nasopharyngeal carcinoma patients and cervical carcinoma patients treated with volumetric modulated are therapy (VMAT).Methods VMAT plans for 10 cervical cancer patients and 10 nasopharyngeal carcinoma patients were transplanted into the Delta4 phantom and calculate the dose,next,implement the treatment on the Varian iX linear accelerator.on the Varian iX linear accelerator.To simulate the setup error by moving the treatment couch in,out,up,down,left,right by 3 mm,5 mm,7 mm.Thereby study the effect of the setup error on the pass rate of the dose verification.Results The results for the dose distribution using the gamma evaluation method showed that the pass rate (3％/3 mm) was less than 90％ when the setup error were greater than 3 mm and 5 mm for the nasopharyngeal carcinoma patients and the cervical carcinoma patients.The pass rate of head direction were (64.7 ± 8.2) ％ and (63.3 ± 3.6) ％ on setup error of 5 mm and 7 mm for nasopharyngeal carcinoma patients and cervical carcinoma patients,respectively.Conclusions Setup error has great effect on the dose verification of the VMAT plans,the greater of the setup error,the lower of the pass rate.The setup error of head direction is more sensitive than other directions especially.
