Objective To set up an antibody-capture ELISA method to detect the Japanese encephalitis virus(JEV)antibody.Methods ELISA plate was coated with the monoclonal antibody which was specific to the envelope protein epitope E39 of JEV,JEV SA14-14-2 strain as the source of antigen was used to absorb the monoclonal antibody,the absorbed virus used to capture the JEV'S antibody.The antibody that captured ELISA was established.The indirect ELISA method using the virus particles from cell culture was compared with coating ELISA plate,105 clinical serum were checked.Results The background in indirect ELISA assay could not be abscised,positive and negative serum diluted in a ratio of 1:10,1:100,1:1000,the relative value of A posative/A negative were 1.02,0.99,1.13,all<2.1.But the antibody-captured ELISA method when the serum dilution was 1:10,1:100,the A posative/A negative were 3.57,2.94,all>2.1;when the dilution was 1:1000,the A posative/A negative was 1.42,<2.1,it meant the method could distinguish the positive and negative serum efficiently when the dilution Was 1:100,the background problem in indirect ELISA assay could be solved.Antibody-capture method was used to check 105 serum samples,the A posative/A negative over a range of 0.257~0.321(0.262±0.050),all<2.1,no positive sample found.Conclusion The antibody-capture ELISA method has been preliminary set up with a high specificity,capable of quickly identifying JEV from other virus.

Vestibular schwannoma is a rare tumor, which is easily misdiagnosed. The authors presented a case of vestibular schwannoma in a 36-year-old woman. The clinical manifestations were recurrent vertigo, hearing loss of the left ear, and tinnitus. The pure tone audiometry threshold of the left ear was 45dBHL with air conduction, and 33 dBHL with bone conduction. A CT scan of the temporal bone region didn't show any abnormal finding. A MRI scan of the head showed nodule abnormal signal in the internal of left vestibular and the narrow of perilymphaticum gap in T2W1 + T2Flair. The initial diagnosis was Meniere's disease. And the post-operation pathologic diagnosis was vestibular schwannoma.

Objective To explore the key way of DUB (dysfunctional uterine bleeding) by traditional and western medicine. Method Analyse the traditional medicine's unique understanding of DUB, the symptoms of DUB and the function of Chinese traditional medicine on DUB. And sum up the modern molecular pathology of DUB. Result Chinese traditional medicine has some regulations in curing DUB. And given the modern molecular biology technique, it maybe play an important part in researching the essential of the syndrome of DUB and the function regulation of Chinese traditional medicine. Conclusion DUB, which is an important disease that is in the person of “menstruation adjustment”, “blooding disease”in traditional Chinese gynecology, must be studied systematically first, so as to improve the combination of traditional medicine and western medicine in gynecology.

Objective To explore the molecular mechanism of elevating placental blood supply by the component from Mongolian Milkurtch and red sage Root. Method Abstract the effective components from Mongolian Milkurtch and red sage Root, apply L-Arginine methy1 ester (L-NAME) to make NO production blocking model, use ELISA to check IL-10 in plasma of 18 d pragant rats, and FISH to check the expression of matricial metal protease-9 (MMP-9) mRNA. Results The plasma level of IL-10 of model group was lower than that of blank group (P 0.05). Conclusion By interving the relationship between IL-10 and MMP-9, the components of Mongolian milkvetch root and red sage root compound may affect the shift and invadation of deciduas, so as to prevent fleet embedding, help building the circulation between mother and embryo, and keep the placental blood supply.

Objective To evaluate the efficacy of ECP and glaucoma drainage device implant in the management of refractory glaucoma. Methods A retrospective study was explored in refractory glaucoma in 99 eyes,in which there were 50 eyes in the ECP group(group A)and 49 eyes in the group of glaucoma drainage device implant (group B). The changes of intraocular pressure (IOP),visual acuity and complication were observed. Results (1)IOP:There was statistically significant difference in IOP between the preoperative and last follow-up in each group(T-Test,t = 2.47,t = 2.51,P < 0.05),and statistically significant difference in IOP between the two groups in the rest of time points of postoperation except the 2 and 7 days after operation.(2)BCVA:T The visual acuity was no statistically significant difference between the two groups(χ2-Test,χ2 = 37.85,P >0.05).(3)Complication:The early complications of the group A included anterior chamber exudation ,short-term high IOP,hyphema. In the group B,the early complications included shallow anterior chamber,hyphema, drainage valve block and high IOP,MSCH,choroidal detachment,while the medium-term complication was glaucoma valve fiber wrapped high IOP and the long-term complications included glaucoma drainage tube rejection , exposure and displacement,and endophthalmitis,conjunctival hyperplasia. Conclusion ECP and glaucoma drainage implant can be effective in the treatment of refractory glaucoma. The ECP has less complications.

The effect of Selenium(Se) on regression of atherosclerosis(AS) induced by feeding quails -with high cholesterol diet was observed. The result indicated that serum cholesterol, triglyceride and lipid peroxide significantly decreased and the ratio of high density lipoprotein cholesterol/total cholesterol increased markedly in Se treated group, that the cholesterol content of aortic tissue and AS index were significantly reduced at the end of the 15th week. It was suggested that Se had a powerful accelerated effect on regression of experimental AS.

Objective:To explore the diagnostic value of 68Ga-prostate specific membrane antigen (PSMA)-11 PET/MR multiparameter multimodal functional imaging in the diagnosis of naive prostate cancer (PCa), and to analyze its efficacy in the early stages of PCa. Methods:From July to September 2019, 45 suspected or pathologically confirmed PCa patients (average age: 69 years) who met the inclusion criteria were collected to perform 68Ga-PSMA-11 PET/MR examination in Nanjing First Hospital. After the scanning was completed, the method of region of interest (ROI) was used to semi-quantitatively calculate the tumor radioactive uptake in the fusion image, including the maximum standardized uptake value (SUV max), tumor metabolic volume (MTV) and mean standardized uptake value (SUV mean), and PSMA expression load was calculated(SUV mean×MTV). Apparent diffusion coefficient (ADC) values of ROI were measured in ADC images ( b=1 500 s/mm 2). The efficacy of 68Ga-PSMA-11 PET/MR in the preoperative diagnosis of PCa and the effect on clinical staging were evaluated with the pathological results. The correlation between prostate specific antigen (PSA) and radiation uptake in PCa tissues, PSMA expression load and ADC values was analyzed by Pearson correlation. Independent-sample t test was used to analyze the data. Results:Pathologically, 38 of the 45 patients were with PCa and 7 patients had benign prostatic hypertrophy (BPH), and metastasis occurred in 12 of the 38 PCa patients. 68Ga-PSMA-11 PET/MR detected 39 cases of PCa with one of which was false-positive. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 68Ga-PSMA-11 PET/MR were 100%(38/38), 6/7, 97.4%(38/39), 6/6 and 97.8%(44/45), respectively. The tumor tissues of PCa often showed focal radioactive uptake, and the T 2 weighted imaging (WI) showed focal low signal and limited dispersion. BPH showed slightly uneven uptake, and T 2WI and diffusion weighted imaging (DWI) showed uneven diffuse signals. SUV max of PCa was significantly higher than that of BPH (24.66±19.21 vs 4.97±2.13; t=5.208, P<0.001). ADC values of PCa were significantly lower than that of BPH ((0.91±0.37)×10 -3vs (1.08±0.24)×10 -3 mm/s 2; t=2.816, P<0.05). SUV max and the expression loads of PSMA in PCa were positively correlated with PSA ( r values: 0.42 and 0.71, both P<0.05). ADC values of tumor tissues in PCa were negatively correlated with PSA ( r=-0.37, P=0.013). Conclusion:68Ga-PSMA-11 PET/MR has great merits in the early diagnosis and staging of PCa.
