AIM:To observe the therapeutic effect of dihydromyricetin on experimental schistosoma japonicum hepatic fibrosis in mice. METHODS:60 mice infected with schistosma japonicum cercariae percutanoeusly were divided into 3 groups:model group,praziquantel group, praziquantel plus dihydromyricetin group and other 20 normal mice were used as control group.After treatment with medicine for 8 weeks,the liver was removed and weighed.The contents of ALT and AST in serum were assayed using the corresponding kits.Moreover, the degree of hepatic fibrosis was observed Via HE and was scored.The expression of collagenⅠprotein and collagenⅢprotein were measured by immunohistochernical method.RESULTS: The mice that infected with schistosoma japonicum, had a featuring increment in liver weights,serum ALT,AST contents,the expression of collagenⅠprotein,collagenⅢprotein (P

To identify the original plant of Daturae Flos from its adulterants by DNA barcoding, the sequences of ITS2, psbA-trnH, matK, rbcL of four species including Datura metel, Darura innoxia, Darura stramonium and Brugmansia arborea were compared and analyzed. The PCR and sequencing success rate of the four regions (ITS2, psbA-trnH, matK, rbcL) was 100%, 90%, 100% and 85%, respectively. Sequences were assembled with CodonCode Aligner. K2P distances were calculated and NJ tree was performed by MEGA 4.1. Thirty SNPs were found among ITS2 sequences, and 33 insert/deletes were found among psbA-trnH intergenic regions. The interspecific K2P distance of ITS2 and psbA-trnH was obviously higher than that of the intraspecific one. As to matK and rbcL, there was no "Barcoding Gap" existing between inter- and intra-specific distances. The NJ trees of the four regions/combinations were built separately. Samples of Brugmansia arborea were clustered into one clade, and the other species of Datura L. formed another clade. The results showed that either ITS2 or psbA-trnH was useful to identify Daturae Flos from its adulterants.

Objective To investigate the correlation between the polymorphisms in GLIS3 and diabetic retinopathy in patients with type 2 diabetes in Northeast China.Methods Based on the case-control study,polymorphisms in GLIS3 were examined by PCR-RFLP in 120 cases of diabetic retinopathy in patients with type 2 diabetes (DR),120 cases of patients with type 2 diabetes without diabetic retinopathy (DNR),and 120 healthy individuals (NC).The odds ratio (OR) and 95％ confidence interval (C I) were calculated using unconditional logistic analysis.Results The resuhs demonstrated that GLIS3 rs7041847 AG,AG/GG genotype,or G allele was associated with an increased risk of DR and DNR (P ＜ 0.05).Moreover,GLIS3 rs7034200 CC,AC/CC genotype,or C allele was associated with an increased risk of DR and DNR (P ＜ 0.05).Conclusion In the patients in Northeast China,the polymorphisms in GLIS3 rs7041847 and rs7034200 were correlated with type 2 diabetes mellitus,while GLIS3 may not be associated with the susceptibility to diabetic retinopathy.

Objective:To explore the change characteristics of event-related potential P300 in different violence risk levels of schizophrenic patients and analyze the risk factors of violence in schizophrenic patients.Methods:Totally 158 schizophrenic patients in Lyuzhou hospital of Shihezi City from January 2019 to August 2020 were collected and assessed with the violence risk scale for 3 days.According to the assessment results, the patients who met the inclusion criteria were divided into low-risk group( n=78), medium-risk group( n=51) and high-risk group( n=29). The auditory P300 of patients in each group was completed within 3 days and act of violence was observed and recorded within one week.Data analysis was carried out by SPSS 20.0 software.The changes of P300 in different violence risk groups were analyzed by ANOVA, and the influencing factors of violence in patients with schizophrenia were analyzed by logistic regression. Results:There was no significant difference in latency of P300 among the three groups (χ 2=4.71, P=0.10), but there was significant difference in amplitude of P300( F=6.67, P<0.01). Compared with the low-risk group ((12.14±9.19) μV), the amplitude of P300 in medium-risk group ((8.25±7.13) μV) and high risk group ((6.71±4.97) μV) decreased significantly ( t=-3.14, -5.45, both P<0.05). There was no significant difference in amplitude of P300 between the high-risk group and the middle-risk group( t=-2.31, P>0.05). The latency and amplitude of schizophrenia patients with violent behavior were significantly different from those without violent behavior ( Z=-6.30, 9.78, both P<0.01). High BVC grade (compared with high-risk group, low-risk group: OR=0.03, 95% CI : 0.00-0.35; the middle risk group: OR=0.09, 95% CI : 0.01-0.62), prolonged P300 latency ( OR=1.30, 95% CI : 1.13-1.48) and decreased P300 amplitude ( OR=0.50, 95% CI: 0.36-0.70), delusion of victimization ( OR=0.12, 95% CI: 0.02-0.76)were the risk factors for violent behavior. Conclusion:The latency and amplitude of P300 can be used as the reliable neuroelectrophysiological indicators for evaluating violence risk in patients with schizophrenia.It has important clinical application value for evaluating violence in patients with schizophrenia.

DRG has been applied in most hospitals.The quality management of the first page of medical records,which is directly related to DRG grouping,has become an important part of hospital management.To some extent,the quality of the first page of medical records affects the inclusion of DRG,the payment of medical treatment,and the performance assessment and evaluation of hospital.Through examples,it focuses on the quality problems of the first page of medical records and its impact on DRG payment,analyzes the reasons leading to the cases of DRG not entered in the group or in the wrong group,and puts forward countermeasures to strengthen the quality manage-ment of the first page of medical records,in order to provide theoretical support and practical reference for hospital management and DRG payment management.
