Objective To understand the dynamics of the treatment and outcomes of advanced schistosomiasis patients in Qianjiang City so as to provide the evidence for improving the future work. Methods All advanced schistosomiasis patients were investigated in Qianjiang City during the period of 2009-2013. Results Totally 1 284 person?times of advanced schistoso?miasis patients received the treatment. The rate of clinical improved was 89.88% and 82 patients were cured. The type of asci?tes was the majority and the megalosplenia type was the second. Conclusion The prevalence of advanced schistosomiasis showed a decreasing tendency but the incidence of new advanced schistosomiasis patients showed a slightly increasing.

Objective To evaluate the protective effect of Fangyouling extracted from herb on Schistosoma japonicum in-fection in the field. Methods The residents in 2 villages Zhaonao Village and Miaochang Village were divided into Group A 139 persons and Group B 162 persons and the residents in Group A embrocated Fangyouling before their contacting the in-fested water and the residents in Group B did not. All the residents were investigated with questionnaires and received the blood and stool examinations for schistosomiasis. Results The positive rates of blood tests were 3.13%and 9.34%in Group A and Group B respectively, the positive rates of stool examinations were 1.92%and 6.44%in Group A and Group B respectively both P values<0.05 . Conclusion Fangyouling has a good protective effect on S. japonicum infection.

Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.

CD47 is a transmembrane protein widely expressed on cell surface, which is considered as a key molecule for immune escape. With an increasing number of related studies, the role of CD47 and its ligands in immunomodulatory effects has been gradually understood. Recent studies have investigated the role of CD47 in ischemia-reperfusion injury of allogenetic kidney transplantation, rejection and xenotransplantation. Nevertheless, the specific role and the key mechanism remain elusive. In this article, the structure and function of CD47, common CD47 ligands, the relationship between CD47 and kidney transplantation, and the application of CD47 in kidney transplantation were reviewed, the latest research progress of CD47 in kidney transplantation was summarized, and the limitations of current research and subsequent research direction were analyzed, aiming to provide reference for subsequent application of CD47 in allogeneic and kidney xenotransplantation.

Objective: To explore the correlation between serum high density lipoprotein (HDL) levels and cognitive function in patients with bipolar disorder. Methods: A total of 99 patients with bipolar disorder were enrolled from the inpatient of Suzhou Guangji Hospital.Serum HDL levels were measured by enzymatic colourimetry.Cognitive function was assessed by the repeatable battery for the assessment of neuropsychological status (RBANS). The relationship between serum high density lipoprotein and cognitive function was analyzed by correlation analysis and stepwise multiple regression analysis. Results: Serum HDL levels ((1.39±0.55)mmol/L)were positively correlated with the RBANS total score (68.92±12.48)(r=0.238, P=0.034) and language score(80.59±15.97) (r=0.239, P=0.033) in patients with bipolar disorder.Stepwise multiple regression analysis showed that serum HDL level was the influencing factor of total score of RBANS(β=4.791, t=2.151, P=0.035)and speech function(β=7.363, t=2.247, P=0.027). Conclusion Serum HDL levels can influence cognitive function, especially speech function in patients with bipolar disorder.
