Bilingual education is an important teaching reform in universities. Since 2006,our college has enacted the attempt for bilingual teaching of pathology,and accumulated abundant experiences during the conducting of the bilingual teaching of pathology.

Objective To investigate the significance of renal tubular dysfunction in patients with refractoriness nephrotic syndrome(RNS)and the effect of interference treatment of Valsartan (VAL).Methods 79 cases of RNS and 68 healthy controls were recruited into the study. The 79 patients of RNS were divided randomly into the VAL group and the dipyridam group. On the basis of routine therapy, the VAL group was given VAL(80mg/d),and the dipyridam group taken dipyridam (150mg/d)orally for 12 weeks The glomerular tubular function(u-RBP,α1-MG,β2-MG,mAlb,NAG)were detected and the pathologic changes of tubukinterstitium were observed by using the methods of ELISA, biochemistry and scoring of the pathologic damage of tubulointerstitium before and after 12 weeks of VAL treatment in all of the cases. Results Urinary RBP,α1-MG,β2-MG,mAlb and NAG in all patients with RNS was evidently higher than that in healthy controls(P＜0.01).Those had positive correlations with damages of tubulointerstitium(r=0.436,0.626,0.499,0.668,0.657,P＜0.01).The interference outcome displayed that the excretion rates of urinary series of protein after oral use VAL in treatment group were markedly lower, while the control group had no distinct change. Conclusion There were various injury of tubulointerstitium and the disfiguration of renal tubular function in all cases with RNS. Damages of renal tubular function had positive correlation with tubulointemtitium injury and renal globular injury. Interference treatment with ARB in patients with RNS could improve renal tubular function, which is of great significance in delaying the progress of RNS.

Some problems are arisen in teaching diagnostic pathology in our college for postgradu-ates of Pathology and Pathophysiology, the students' basic knowledge is weak, the cycle is short, the teaching team and resources are relatively insufficient. To promote the cultivation of graduate students, we should carry out the CBL teaching method, add the clinical practice and training, strengthen the teaching staff, and apply digital section and network platform.

At present, the experimental examination of medical morphology courses in most medical colleges and universities still adopt traditional specimen examination or PPT examination, and there are many disadvantages. This paper introduces how to build a system with B/S architecture based on the local area network, and how to set up an examination system to realize the functions of user management, online examination database updating, free examination paper formation, examination running and automatic marking. Through its application in our school in recent years, the medical morphology online picture exam system has effectively promoted the reform of the examination methods, the style of study and the effect of experimental teaching. However, there are still some problems, such as high investment cost and limited examination room.

OBJECTIVE: To find an objective and accurate examination for evaluation of spinal cord injury (SCI) in forensic clinical medicine. METHODS: The onset latency of cortex, peak latency of N1, central motor conduction time (CMCT) and wave width of the abductor pollicis brevis and the anterior tibialis were calculated by transcranial magnetic stimulation-motor evoked potential (TMS-MEP). The data of 68 patients suffered from SCI including 23 cervical levels and 45 thoracolumbar levels were collected and compared with that of 30 normal controls. RESULTS: In experimental group, when the muscle strength of the abductor pollicis brevis or the anterior tibialis decreased or disappeared, the onset latency of cortex, the peak latency of N1, and CMCT prolonged and the wave width broadened. And these indexes of grade 2 and 3 muscle strength in experimental group were higher than that in the control group (P < 0.05). CONCLUSION The TMS-MEP can determine directly and objectively the motor functional status of pyramidal tract of spinal cord in order to provide more accurate and objective evidences in forensic medicine.

To establish a case-based learning (CBL) database of Pathology for medical students in imaging specialty, which includes chief complaints and history of present illness, case characteristics, imaging findings, questions, surgical findings and discussion. Cases in the CBL database was obtained from newly resected specimen, which were combined with various imaging test results of patients before surgery. All the information of each case, including postoperative pathological diagnosis report, was collected to perfect the database. The database was used in the CBL teaching of pathology, which has stimulated students' learning initiative and enthusiasm, cultivated their logic thinking of imaging diagnosis and improved the teaching effect.

Objective:To investigate the diagnostic value of 3.0T magnetic resonance with high b-value diffusion weighted imaging (DWI) for endometrial carcinoma (EC).Methods:The clinical data of 118 patients with suspected endometrial lesions were analyzed retrospectively. Among them, 83 cases were pathologically diagnosed as EC (EC group), and 35 cases were diagnosed as complex or atypical hyperplasia (endometrial hyperplasia group). In addition, 47 patients with normal endometrial (normal endometrial group) in the same period were selected. All patients underwent 3.0T MRI conventional T 2-weighted imaging (T 2WI) and multiple b-value (0, 300, 400, 600, 800, 1 000, 2 000, 3 000 and 4 000 s/mm 2) DWI scans. The endometrial signal intensity on different b-value DWI was measured. The b-value-endometrial signal intensity curve was drawn, and the decline degree of endometrial signal intensity was calculated. Results:When b-value was 300, 400, 600 and 800 s/mm 2, there was no significant difference in endometrial signal intensity among the three groups ( P>0.05); when b-value was 1 000, 2 000, 3 000 and 4 000 s/mm 2, the signal intensity in EC group was significantly higher than that in normal endometrial group and endometrial hyperplasia group (456.1 ± 119.4 vs. 371.3 ± 99.9 and 381.6 ± 184.8, 284.2 ± 91.9 vs. 163.2 ± 46.5 and 191.4 ± 110.8, 196.7 ± 72.4 vs. 103.7 ± 30.9 and 129.4 ± 83.1, 151.6 ± 54.8 vs. 74.6 ± 20.8 and 101.1 ± 60.7), and there was statistical difference ( P<0.05); while there was no significant difference between normal endometrial group and endometrial hyperplasia group ( P>0.05). The results of b-value-endometrial signal intensity curve showed that the decrease of endometrial signal intensity in EC group was significantly lower than that in normal endometrial group and endometrial hyperplasia group (0.79 ± 0.05 vs. 0.90 ± 0.03 and 0.87 ± 0.04), the index in endometrial hyperplasia group was significantly lower than that in normal endometrial group, and there was statistical difference ( P<0.05). Conclusions:High b-value DWI is useful for the differentiation of benign and malignant endometrial lesions, and it can improve the qualitative diagnostic value of EC.

OBJECTIVE: To assess the value of copy number variation analysis based on next generation sequencing (CNV-seq) in prenatal diagnosis for women at advanced maternal age. METHODS: A prospective analysis was carried out for women who underwent amniocentesis at 18~36 weeks of gestation for fetal CNV-seq for advanced maternal age. RESULTS: For 1461 unrelated Chinese women with a singleton pregnancy, CNV-seq was performed for all samples successfully. The proportion of chromosomal abnormalities was 2.3% (34/1461), of which 44.12% were submicroscopic copy number variations (<5 Mb). CONCLUSION Pregnant women at an advanced maternal age should be informed for not only common trisomies but all pathogenic chromosomal aberrations. NGS was a sensitive and accurate approach for detecting CNVs.

Objective: To investigate the clinical efficacy of cevimeline as a pharmacotherapeutic approach to stimulating gland activity in improving the symptoms and signs of primary Sjögren syndrome (pSS). Methods: Sixty-three patients diagnosed with pSS who attended the Affiliated Huai'an Hospital of Xuzhou Medical University from January 2018 to September 2019 were included in this trial. They were randomly assigned to the therapeutic group and control group. All patients were recalled at baseline and after 2 weeks, 3 months and 6 months. Measurement of salivary and lacrimal flow as well as evaluation of subjective symptoms was performed at the follow-up. Results: Fifty-eight patients completed the trial and were included in the statistical analysis. There was a significant difference between the two groups in the measurement of salivary and lacrimal flow at the second week and third month (P < 0.05). Improvement in subjective symptoms of oral, ocular and gland was detected at the third month (P < 0.05). At the sixth month, compared with the control group, only the salivary gland symptom score of the treatment group was statistically significant (P < 0.05). Conclusion Cevimeline has good specificity and safety and can increase salivary and lacrimal flow and improve subjective symptoms of pSS in a short time.
