The new era imposes heightened demands on medical professionals,who must not only possess a solid theoretical foundation but also exhibit strong practical skills and innovative capabilities.The quality of medical func-tional laboratory construction is crucial for cultivating high-caliber medical talents.In light of the current developmental status and trends regarding functional experiment teaching within Chinese higher education institutions,particularly the disparities in development across various regions and institutions,the Functional Experiment Teaching Committee of the Chinese Pathophysiology Society has developed an expert consensus on laboratory construction standards.This consensus was established through comprehensive investigations,research,and extensive discussions to provide a reference for di-verse institutions to continuously enhance their levels of laboratory construction.

Objective Evaluating the effect of situational questions for qualifying the students'abilities in physiolo-gy examination .Methods Comparing the difficulty coefficients and discrimination indexes between situational and traditional choice questions .Results Compared with the traditional choice questions , the difficulty coefficient of situational questions increased , while the discrimination indexes were more reasonable .The discrimination indexes of situational understanding questions were higher than those of the traditional memory and understanding questions . There were no difference between discrimination indexes of the situational application questions and those of tradi -tional application questions .Conclusions Situational questions not only improved the quality of examinations , but also facilitate evaluating students'learning ability .

Objective To study the relation between mitochondria damage and glutamate excitotoxicity in motor neuron disease.Methods Organotypic cerebral cultures were prepared from prefrontal brain of neonatal SD rats. Mitochondria was damaged by malonate sodium, and a NMDA receptor antagonist, MK-801 of 0.025,0.050,0.075,0.100 mmol/L, was respectively added into the cerebral cultures simultaneously in the protective experiment. The morphology of motor neurons was shown by Nissl and anti-high molecular weight filament (anti-NFH) immunohistochemical staining, and number of motor neurons was counted. The concentration of MDA in culture medium was measured by MDA assay. Results After exposed to malonate sodium (0, 1, 3, 5 and 7 mmol/L) for 1 week, the number of motor neurons in cerebral slices showed a dose-dependent decrease (49.78?4.30, 47.89?6.81, 25.67?6.18, 4.44?3.40, 1.22?1.99). The group treated with 3 mmol/L malonate sodium was selected as damage group. In protective experiment, the number of motor neurons in 0.050, 0.075 and 0.100 mmol/L MK-801-treated groups was significantly increased as compared with damage group, still less than that of controls. However, there was no difference of number of motor neurons among these three groups. The concentration of MDA in culture medium in normal control and 3, 5 mmol/L malonate sodium was (13.47?0.49), (15.87?0.74), (20.52?0.74) mmol/L. When treating cerebral cultures with 0.050 mmol/L MK-801 and 5 mmol/L malonate sodium simultaneously, the MDA was decreased to 14.45?0.78, close to normal level. Conclusion Glutamate excitotoxicity plays a role in motor neuron diseases caused by mitochondria damage, there exists a close relationship between glutamate exicitotoxicity and mitochondria damage.

Tumor infiltrating lymphocytes(TILs) were isolated by enzymatic digestion and discontinuous gradient centrifugation from 8 human advanced tumors (4 stomach carcinoma, 2 liver cancer, 1 non-small-cell lung carcinoma and 1 colon cancer). These cells were cultured in complete RPMI 1640 medium supplemented with l000U/ml of rhIL2 for 4-6 weeks, till the cell number reach over l09/total, reinfused to the same patients i.v. meanwhile, the patients received 105U of rhIL2 i.m for 5 days. One week before and one month after TIL infusion periphery blood from the patients was collected and the mononuclear cells were isolated. Cytotoxicity against a panel of tumor cell targets by MTT colorometric assay and lymphocyte phenotype by two-color flow cytometry were mornitored. The results showed that there was significant increase in the killing ability to the tested tumor targets to different extent, especially the killing to the target cells which shared the same histological type with the patients tumor.
