Agricultural Microbiology is a professional foundation curriculum for biology,botany and envi-ronmental majors in agricultural universities.After 1999,with the increase enrollment of the national under-graduate education and rapid construction of the university,the number of majors and students increased rapidly and quality of students and talent demand of society changed dramatically.Under such condition,in order to meet the society demand of microbiology,according to the distinguishing feature of different major groups,based on strengthening the basis teaching and stretching application teaching,new curriculum teaching model and method were explored positively,and then new curriculum system was constructed.Be-ing aroused sufficiently of the students’ subjective initiative,both the teaching quality and comprehensive quality were improved.

Objective To study the balance function of normal persons and to explore the differences in gender and age groups.Methods Forty parameters of 445 normal persons(16-70 years old, 205 of male, 240 of female ) were detected by static posturography while they were in seat, double foot standing with opening and closing eyes, and single foot standing with opening eyes. The results of male and female, standing with opening eyes and closing eyes, left foot standing and right foot standing were compared.Results Everyone's center of gravity was distributed in A zone while they were in seat. At standing with opening eyes and closing eyes, the center of gravity in A zone were in 429 subjects( 96.4%) and 436 subjects( 98.0%). Most parameters showed significant difference between the women and the men, opening eyes and closing eyes, left foot standing and right foot standing, different age groups. The stability in closing eyes was better than that in opening eyes, right foot standing was better than left foot standing. Most values of 20—39 years old group were the best, 70—79 years old group were the worst.Conclusion Static posturography can evaluate human balance function objectively and quantitatively. The stability is related to age and gender. To judge the balance function, the subject's age and sex must be taken into account.

Objective To establish the normal parameters of psychometric measures such as the number connection tests A(NCT-A)and digit symbol tests(DST)in assessment of minimal hepatic en- cephalopathy(MHE).Methods One hundred and sixty healthy volunteers(aged 25 to 64 years;educa- tional level＞9 years)were divided into＜35 ys,35～44 ys,45～54 ys and 55～64 ys groups.All of the healthy volunteers were assessed with NCT-A and DST to establish the normal value of age-related parameters,which can be used for diagnosis of MHE in patients with liver cirrhosis.Two standard devi- ation of the normal mean was used as a diagnostic criterion for MHE.One hundred and six cirrhotic patients were assessed with these parameters.Results The parameters of NCT-A were(25.1?4.6) sec in＜35 ys group,(32.1?6.8) sec in 35～44 ys group,(38.6?7.1)sec in 45～54 ys group or (49.3?6.3)sec in 55～64 ys group.The scores of DST were 49.9?4.7 in＜35 ys group,44.6?4.8 in 35～44 ys group,38.5?5.0 in 45～54 ys group or 35.4?4.7 in 55～64 ys group.Thirty one out of 106 cirrhotic patients were diagnosed as MHE based on these parameters.Conclusion The NCT- A and DST are psychometric assessments for diagnosis of MHE.Age-based normal paramerters of NCT- A and DST are needed to be established.

Objective To study the clinical features and to improve the treatment on the elderly patients with brain tumor.Methods Retrospective analysis of 163 cases with brain tumor which had been confirmed by CT,MRA or pathology.Results Of all the 163 cases,121 were located in supratentorium,most of which were meningiomas and gliomas.Most patients(129 cases)had comorbidity.After operation,symptoms disappeared or obviously improved in 126 cases,moderately improved in 19 cases,and did not changed in 6 patients.Twelve cases died after operation in a month, in which 9 patients were over 75 years old.The death rate of operation was 6.1%.Conclusions It is important to know the atypical manifestation of brain tumor in the elderly,which may prevent clinical misdiagnosis and mistherapy.The perioperative management is indispensable to the prognosis of the patients.The choice of operation and medication should be in individualized.

Objective To evaluate the clinical effect of posterior decompression, internal fixation and interlaminar fusion for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment. Methods A retrospective study was carried out in 27 cases of severe osteoporotic vertebral fractures complicated with spinal canal encroachment. The patients were treated with posterior decompression, internal fixation and interlaminar fusion during the period from January 1, 2009 to December 31, 2014. All patients were given vertebral pedicle screw fixation after pedicle augmentation with bone cement. The pain scores of visual analogue scale(VAS), Oswestry Disability Index(ODI), Cobb angle , thoracolumbar Cobb angle and the recovery of neurological function(estimated by Frankel grading system) of the patients were compared beforeoperation, one week after operation and at the end of follow-up. The incidences of internal fixation failure, adjacent vertebral fracture and bone cement leakage also were recorded. Results The patients were followed up for an average of 27 months. The spinal canal occupation rate caused by fracture fragment of posterior vertebral wall was 27.41%~63.85%, with an average of(43.24 ± 10.61)%. Postoperative VAS pain scores, ODI, Cobb angle and thoracolumbar Cobb angle were statistically different from those before operation (P < 0.05). The correction rate for Cobb angle and thoracolumbar Cobb angle was (63.31 ± 23.47)%, (61.91 ± 17.54)%respectively. At the end of the follow-up, the correction loss rate for Cobb angle and the thoracolumbar Cobb angle was (15.38 ± 39.92)%, (21.79 ± 32.20)% respectively, the difference being insignificant compared with those one week after operation(P>0.05). In respect of Frankel grading of neurological function at the end of the follow-up, 6 cases were in grade D and 19 cases were in grade E, but the differences were insignificant compared with those before operation (P > 0.05). None of the patients had surgical site infection, screw looseness or breakage, or rod breakage during the follow-up period. There were 8 patients with asymptomatic bone cement leakage after operation. Vertebral compression fractures recurred in 5 patients, of which 2 had adjacent vertebral fractures and 3 had non -adjacent segment. Conclusion The therapy of posterior decompression, internal fixation and interlaminar fusion is effective for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment by obviously relieving pain, improving the physiological function of the spine and stabilizing the spine.

BACKGROUNDRecent clinical and preclinical studies have suggested that deep brain stimulation (DBS) can be used as a tool to enhance cognitive functions. The aim of the present study was to investigate the impact of DBS at three separate targets in the Papez circuit, including the anterior nucleus of thalamus (ANT), the entorhinal cortex (EC), and the fornix (FX), on cognitive behaviors in an Alzheimer's disease (AD) rat model.

METHODSForty-eight rats were subjected to an intrahippocampal injection of amyloid peptides 1-42 to induce an AD model. Rats were divided into six groups: DBS and sham DBS groups of ANT, EC, and FX. Spatial learning and memory were assessed by the Morris water maze (MWM). Recognition memory was investigated by the novel object recognition memory test (NORM). Locomotor and anxiety-related behaviors were detected by the open field test (OF). By using two-way analysis of variance (ANOVA), behavior differences between the six groups were analyzed.

RESULTSIn the MWM, the ANT, EC, and FX DBS groups performed differently in terms of the time spent in the platform zone (F(2,23) = 6.04, P < 0.01), the frequency of platform crossing (F(2,23) = 11.53, P < 0.001), and the percent time spent within the platform quadrant (F(2,23) = 6.29, P < 0.01). In the NORM, the EC and FX DBS groups spent more time with the novel object, although the ANT DBS group did not (F(2,23) = 10.03, P < 0.001). In the OF, all of the groups showed a similar total distance moved (F (1,42) = 1.14, P = 0.29) and relative time spent in the center (F(2,42) = 0.56, P = 0.58).

CONCLUSIONSOur results demonstrated that DBS of the EC and FX facilitated hippocampus-dependent spatial memory more prominently than ANT DBS. In addition, hippocampus-independent recognition memory was enhanced by EC and FX DBS. None of the targets showed side-effects of anxiety or locomotor behaviors.

OBJECTIVETo study the impact of the chloride channel dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) on the cytoskeleton of Sertoli cells in the mouse.

METHODSTM4 Sertoli cells were cultured and treated with CFTR(inh)-172 at the concentrations of 1, 5, 10 and 20 μmol/L for 48 hours. Then the cytotoxicity of CFT(inh)-172 was assessed by CCK-8 assay, the expressions of F-actin and Ac-tub in the TM4 Sertoli cells detected by immunofluorescence assay, and those of N-cadherin, vimentin and vinculin determined by qPCR.

RESULTSCFTR(inh)-172 produced cytotoxicity to the TM4 Sertoli cells at the concentration of 20 μmol/L. The expressions of F-actin and Ac-tub were decreased gradually in the TM4 Sertoli cells with the prolonging of treatment time and increasing concentration of CFTR(inh)-172 (P < 0.05). The results of qPCR showed that different concentrations of CFTR(inh)-172 worked no significant influence on the mRNA expressions of N-cadherin, vimentin and vinculin in the Sertoli cells.

CONCLUSIONThe CFTR chloride channel plays an important role in maintaining the normal cytoskeleton of Sertoli cells. The reduced function and expression of the CFTR chloride channel may affect the function of Sertoli cells and consequently spermatogenesis of the testis.

OBJECTIVETo evaluate and analyze the mechanism of Pizhen for the treatment of patients with scapular muscle fasciitis.

METHODSOne hundred and sixteen patients were divided into two groups according to random number table method, 58 cases in the treatment group and 58 cases in the control group. After treatment, 109 patients were followed up, and 7 patients lost follow-up (2 cases in the treatment group and 5 patients in the control group). In the treatment group, there were 15 males and 41 females, with a mean age of (28.02 +/- 4.85) years; the course of disease ranged from 0.25 to 3 years; and the patients were treated by Pizhen once a week,and 2 weeks were one treatment course. In the control group, there were 19 males and 34 females, with a mean age of (27.23 +/- 4.54) years old; the course of disease ranged from 0.25 to 1 year; and the patients were treated by acupuncture massage instrument, 20 minutes at a time,once a day for 2 weeks. Soft tissue displacement and banana area were tested by a soft tissue tension tester, pressure value was measured by pressure measuring instrument, and VAS was recorded by pain visual analog scale record.

RESULTSThere were significant differences in tissue displacement, banana area, pressure value and VAS between two groups before and after treatment. The tissue displacement and pressure value in the treatment group were higher than those in the control group,while banana area and VAS were lower than those in the control group. In the treatment group, 30 patients healed, 13 patients got marked improvement, 12 good and 1 poor;while 16 patients healed, 19 patients got marked improvement,11 good and 7 poor in the control group. The therapeutic effects in the treatment group was better than that in the control group.

CONCLUSIONPizhen is an effective method to treat pain in patients with scapular muscle fasciitis by relaxing tendon of soft tissue around pain point of scapular and relaxing compress and stimulation of nerves.
