Objective:To study the effective treatment method for sterility. Methods: 126 cases with sterility were divided into three groups at random. 42 cases were in group A treated with Tiaojingcuyun pill, 38 cases group B were treated with clomophene as the control groups, and 46 cases were in group C with Tiaojingcuyun pill matching clomophene as the study group. Results: During 138 treatment periods 22 cases in group C got pregnancy. the rate of pregnancy was 47.83%. As compared with group A and group B, the rate of pregnancy increased obviously. There were significant differences among them ( P

Objective To investigate the effect of zinc finger protein A20 expression on lipopolysaccharide(LPS)response in human monocytes so as to discuss its regulation roles and mechanism to inflammation in vivo and its potential value of clinical application.Methods Cell transfection technique was respectively used to make zinc finger protein A20 transgenic cell model and gene silence cell model,both of which were then treated with LPS.Real-time reverse PCR was employed to analyze the expression of zinc finger protein A20 and ELISA to determine the activity of nuclear transcription factor NF-?B and the levels of dependent inflammatory cytokines including tumor necrosis factor(TNF)alpha.Results After LPS treatment,the NF-?B activity and the TNF-alpha level were significantly lower in the cells with overexpressed zinc finger protein A20 than LPS control cells(P

Objective:To investigate the value of evaluating pancreatic exocrine insufficiency with fecal pancreatic elastase-1 in the clinical staging of chronic pancreatitis and prognosis evaluation.Methods:A total of 100 patients with pancreatic exocrine insufficiency (patient group) who received treatment in Wenzhou Central Hospital from January 2021 to June 2022 and 100 subjects without pancreatic exocrine insufficiency (control group) were included in this study. Fecal pancreatic elastase-1 content was measured by an enzyme linked immunosorbent assay. The receiver operating characteristic (ROC) curve was plotted to evaluate the value of fecal pancreatic elastase-1 content in the diagnosis of pancreatic exocrine insufficiency. Fecal pancreatic elastase-1 content was compared among patients with different clinical stages of chronic pancreatitis. The factors that affect the prognosis of patients with chronic pancreatitis were analyzed using logistic regression analysis.Results:Pancreatic elastase-1 content in the patient group was (63.28 ± 13.24) μg/g, which was significantly lower than (768.29 ± 102.59) μg/g in the control group ( t = 68.16, P < 0.05). The sensitivity, specificity, Youden index, and 95% CI of using pancreatic elastase-1 content to diagnose pancreatic exocrine insufficiency were 74.7%, 63.5%, 0.724, and 0.740-0.870, respectively. Among the 200 included subjects, 103 had chronic pancreatitis. With the increase in M-ANNHEIM clinical stage, fecal pancreatic elastase-1 content in patients with chronic pancreatitis gradually decreased ( F = 182.66, P < 0.05). Pancreatic elastase-1 content < 200 μg/g was used as a standard to evaluate pancreatic exocrine function. Results showed that 35 patients had stage I chronic pancreatitis, 40 patients had stage II chronic pancreatitis, and 28 patients had stage III chronic pancreatitis. There was no significant difference in the number of patients with different stages of chronic pancreatitis between the two clinical stage classification methods ( χ2 = 12.46, P = 0.002). Six-month follow-up results showed that among 103 patients with chronic pancreatitis, 31 had a poor prognosis (30.1%). Univariate analysis revealed that there were significant differences in age at onset, body mass index, triglyceride level, alcohol consumption, and pancreatic elastase-1 content among patients with different prognoses ( χ2 = 24.07, 4.27, 5.43, 8.38, 4.93, P < 0.05). Multivariate logistic regression analysis showed that age at onset, body mass index, triglyceride level, alcohol consumption, and pancreatic elastase-1 content were the independent influential factors of prognosis in patients with chronic pancreatitis [ OR (95% CI) = 4.207 (2.741-11.609), 1.870 (1.241-2.972), 1.984 (1.437-3.113), 2.769 (1.827-5.125), 1.951 (1.469-3.387), all P < 0.05]. Conclusion:Pancreatic elastase-1 content is of great value in assessing pancreatic exocrine insufficiency, and is closely related to the clinical staging and prognosis of patients with chronic pancreatitis. Therefore, fecal pancreatic elastase-1 content is expected to be a reliable reference for assessing the progress of chronic pancreatitis and predicting its prognosis.

Objective:To investigate the changes in gray matter volume (GMV) and abnormalities in structural covariant network (SCN) patterns in patients with chronic pontine infarction (PI).Methods:Patients with unilateral chronic PI (case group) with the first onset admitted to the First Affiliated Hospital of Zhengzhou University and Tianjin Medical University General Hospital from October 2014 to June 2021 were prospectively included. At the same time, healthy subjects matched with age, gender and education years (normal control group) were included. High-resolution three-dimensional T 1 structural MRI images and behavioral scores of the subjects were collected. The voxel-based morphometry and two-sample t test were used to explore the differences in GMV between the groups. Using GMV differential brain regions as seed points, SCN was constructed to explore the abnormality of structural covariant patterns in patients with PI. Spearman rank correlation analysis was used to analyze the correlation between GMV in differential brain regions and behavioral scores. Results:A total of 60 patients with PI were enrolled, including 33 left PI and 27 right PI, while 34 healthy controls were also enrolled. Compared with the normal control group, the GMV in bilateral posterior cerebellar lobe decreased significantly in the left PI group, and the GMV in left anterior and posterior cerebellar lobes and the right posterior cerebellar lobe decreased significantly in the right PI group (Gaussian random field correction with voxel level P<0.001 and cluster level P<0.05, cluster voxel >20), and there was a significant correlation between GMV values in the left anterior and posterior cerebellar lobes and the right posterior cerebellar lobe and the motor function score ( P<0.05). In addition, compared with the normal control group, the right PI group had broader covariate brain regions and a significant increase in the number of structural connections between covariate brain regions (family-wise error correction with voxel level P<0.05, cluster voxel >20). Conclusions:The GMV in bilateral posterior cerebellar lobe decreases significantly in patients with chronic PI, and were secondary to broader covariate brain regions and structural connections. This may be the neural mechanism of impaired behavioral function in patients with PI.

【Objective】 To learn the production efficient of platelet components among prefecture-level blood stations in China, to provide supporting data for those blood stations to optimize the production mode of platelet components and continuously improve production efficiency and supply capacity. 【Methods】 The data from 2017 to 2020 was obtained from 24 prefecture-level blood stations who were the members of the practice comparison network for blood institutes in China. The collection units of apheresis platelets, the number of dual-collections of apheresis platelets and plasma, the average apheresis units of one platelet apheresis procedure, the discarded rate of apheresis platelets, the amount of expired apheresis platelets and the amount of apheresis platelets issued were collected. For concentrated platelets, the prepared amount of platelet concentrates and the amount of expired platelet concentrates were collected; both the quantity of qualified and issued concentrated platelets were submitted for statistical analysis.The total output and efficiency of platelet components were calculated based on the collected data. 【Results】 The average annual growth rate of apheresis platelets collection in 24 prefecture-level blood stations was 12.23%, accounting for 99.80% of the total platelet output; the average collection unit of one platelets apheresis procedure was 1.75; from 2019 to 2020, only 5 blood stations performed dual-collection of platelet and plasma during one apheresis procedure; the discarded rate of apheresis platelets was 0.28%, of which 0.007% was due to expiration. A total of 1 621.2 therapeutic units of concentrated platelets were prepared, and 13.03% of them was discarded due to the expiration. The production efficiency of platelet components was 97.56%, of which the production efficiency of apheresis platelets was 97.61% and the production efficiency of concentrated platelets was 74.43%. 【Conclusion】 There are large regional differences in the supply capacity of platelet components in prefecture-level blood stations. Apheresis platelets are the main resource of platelet components product, and the collection capacity is increasing over the years with the characteristics of high production efficiency and low expiration scrapping rate. However, the preparation of concentrated platelets are still limited with relatively low production and high expiration discarded rate.
