Objective To establish an indirect immunofluorescence assay for detection of murine norovirus ( MNV) .Methods Mouse leukaemic monocyte macrophage cell line RAW 264.7 cells were infected with MNV-1 and cultured for 36 hours to collect the virus and uninfected cells , and to make antigen glass slides .BALB/c mice were gavaged with MNV-1 (107 TCID50) and infected sera were collected as positive control .The serum was 1:10 diluted and used for measuring MNV antibody by immunofluorescence assay ( IFA ) .80 serum samples were tested using the two methods , IFA and ELISA, and the discrepant samples were validated by Western blotting .Results RAW264.7 cells were infected with MNV-1 for 36-48 h, showing an infection rate of 60% of the cells, and the cells infected for 36 h were preferred.IFA method was used to detect the serum with MNV-1 infection and showed that the antibody content was gradually increased at one week after infection , reaching a maximum antibody concentration at 4 weeks after infection , and maintained a stable level later .The mouse serum at four weeks after MNV-1infection was used as positive quality control . Among the 80 serum samples , 27 positive and 53 negative cases were detected by IFA method , and 32 positive and 48 negative cases were detected by ELISA .The five discrepant samples were verified by Western blotting , resulted in 3 positive and 2 negative cases . The coincidence rate of IFA was 96.0% and that of ELISA methods was 97.5%. Conclusions Basically, immunofluorescence assay can be used to detect the MNV-1 infection in mice, although false negative result may occur occasionally .IFA and ELISA detection can be selected as initial screening measures , and use Western blot assay to verify the discrepant samples .

Objective To compare Montreal cognitive assessment-basic ( MoCA-B ) and mini-mental state examination (MMSE) in screening cognitive dysfunction of acute stroke patients. Methods The cognitive function of patients (n=83) with acute stroke onset within 10 days (including new cerebral infarction and cerebral hemorrhage) were assessed using MMSE and MoCA-B. The classification of patients with cognitive impairment was compared between the two scales. The consistency of cognitive impairment and affected domains assessed by MMSE or MoCA with experts were evaluated. Results ①There were 32 cases (38.6%) with abnormal MMSE score and 40 cases (51.8%) with abnormal MoCA-B score. ②The the diagnostic consistency of MoCA-B with experts was 89.16%. The false positive of MMSE was 2.41%and the false negative (rate of missed diagnosis) was 16.87%.False positives of MoCA-B were 4.82%and false negatives (rate of missed diagnosis) were 6.02%.③Among the 51 patients with normal MMSE, 15 had abnormal MoCA-B (29.4%). There were significant differences between these two score system in executive function, verbal fluency, directivity, abstraction, delayed recall, visual perception, naming and other cognitive domains (P＜0.05). Conclusion MoCA-B scale may be more sensitive and better than MMSE scale in screening for cognitive impairment in patients with acute stroke.

Objective To investigate the effect of L-asparaginase on the coagulation function of patients with acute lymphoblastic leukemia. Methods The general information of 100 patients with acute lymphoblastic leukemia from January 2013 to January 2017 admitted in the Department of Hematolog was retrospectively analyzed. All patients received no anticoagulation before chemotherapy. All patients were treated with routine treatment after admission, namely with vincristine + daunorubicin + prednisone induction therapy and then with VDLP regimen chemotherapy, combined with intravenous injection of L-asparaginase 8000 U/m2, once every other day. After 3 months of treatment, its clinical efficacy was evaluated, and adverse reactions during treatment were observed. The changes of coagulation indexes were compared before treatment and at 1 day and 7 days after treatment. Results Of the 100 patients, there were 22 cases of complete remission, 40 cases of partial remission, 26 cases of stable condition and 12 cases of progression, with total efficiency of 62％(62/100). During the treatment of 100 patients, 10 cases had allergy, 9 had a drop in white blood cell count, and 8 had gastrointestinal reactions including nausea and vomiting. On the first day after treatment, the levels of PT, APTT and TT in 100 patients were significantly higher than those before treatment, with significant difference (P＜ 0. 05 or P＜0. 01). However, the FIB level in patients was significantly lower than that before treatment, with significant difference (P＜0. 05). There were no significant differences between the levels of PT, APTT and TT in all patients at one week after treatment and those before treatment (P＞0. 05). Although FIB level in all patients at one week after treatment increased compared with that at one day after treatment, the difference had no significant difference. While the level of FIB was significantly lower than that before treatment, and the difference was significant (P＜0. 05). Conclusion L-asparaginase is effective and safe in the treatment of acute lymphoblastic leukemia, but it is easy to produce adverse reactions such as abnormal coagulation function. Therefore, the clinical application of L-asparaginase in the treatment of acute lymphoblastic leukemia should be dynamically monitored in patients in order to actively correct coagulation disorders, and the drug should be discontinued when necessary.

Objective To investigate the risk factors for HIV and HCV infections in patients receiving methadone maintenance treatment (MMT) in Kaiyuan,Yunnan province.Methods Patients receiving MMT in June 2014 in Kaiyuan were included in this study.The prevalence of HIV and HCV infections were calculated and logistics regression analysis was conducted to identify related risk factors.Results In June 2014,275 patients received MMT,their average duration of MMT was 4.0 ± 2.4 years.The overall HIV infection rate was 51.6％ (142/275).All the HIV infection occurred before MMT.In 275 patients,222 were infected with HCV before MMT,and 17 new HCV infections occurred during MMT.And the HIV/HCV co-infection rate was 49.1％.The results from multivariate logistic regression analysis indicated that the risk of HIV infection was higher in those who were unmarried/divorced/widowed (adjust OR=2.39,95％CI:1.29-4.43) and injecting drug users (adjust OR=5.52,95％CI:2.69-11.35),sharing needles with others (adjust OR=2.32,95％CI:1.04-5.18) and had longer history of drug use.For HCV infection,injecting drug use was the independence risk factor(adjust OR=11.54,95％CI:4.79-27.80).Conclnsion The prevalence of HIV,HCV infections and HIV/HCV co-infection in patients in MMT clinic were higher in Kaiyuan than in other areas in Yunnan.More intervention should be given to the patients who had history of injecting drug use.

Objective:To systematic review the efficacy and safety of external application of traditional Chinese medicine on treatment of breast cancer related lymphedema.Methods:CNKI, Wanfang Data, VIP, Sino-Med, The Cochrane Library, PubMed, Web of Science were searched for related randomized controlled trials, the retrieval time was from inception to May 25, 2020. Two researchers independently screened and evaluated the included studies. Meta-analysis was performed by RevMan 5.4 software.Results:A total of 16 studies involving 1 315 patients with breast cancer related lymphedema were included, and the methodological quality of the included studies was not high. Compared with conventional treatment, external application of traditional Chinese medicine combined with conventional treatment had advantages in improving the total efficiency( P<0.01) and quality of life( P<0.01), reducing pain( P<0.01) and improving upper limb function( P<0.01), without obvious adverse reactions( P>0.05), but there was no improvement in depression( P>0.05). Compared with conventional treatment, external application of traditional Chinese medicine could improve the total efficiency( P<0.01). Compared with placebo sticker combined with conventional treatment, external application of traditional Chinese medicine combined with conventional treatment can reduce circumference( P<0.05) and reduce pain( P<0.01), without obvious adverse reactions( P>0.05). Conclusions:Available evidence suggests that external application of traditional Chinese medicine may be a potential treatment method for breast cancer related lymphedema. Due to the poor methodological quality of the included studies, high-quality randomized controlled trials are still needed.
