ObjectiveTo analyze the potential risk of infection sources during the consolidation phase of schistosomiasis elimination in Lushan County (a mountainous region) of Sichuan Province, and to provide prevention and control strategies for the consolidation of schistosomiasis elimination achievements in mountainous areas. MethodsIn 2024, one to two villages with historically severe epidemics were selected in the heavily endemic townships of Lushan County as monitoring sites to carry out monitoring for wild animal feces, domestic animals, wild rats, free-roaming dogs, local residents, and mobile populations. Follow-up monitoring for previously infected individuals was carried out in Caoping Village of Siyan Town. Statistical analyses were performed to assess the risks associated with infection sources. ResultsA total of 115 fecal samples from 13 species of wildlife were incubated, with all negative. Blood tests were conducted on 492 cattle, 34 sheep, and 261 dogs, with all negative. A total of 2 520 rodent traps were set, capturing 67 wild rats with a capture rate of 2.66%, and no positive wild rats were found upon dissection. The activity track of 25 loose dogs was 2 212 meters at the farthest, 236 meters at the nearest, and 744 meters on average. a total of 68 wild droppings (all dog feces) were picked up along the way, with all negative. Blood tests were performed on 3 540 local population, yielding 39 blood-positive cases with a blood positive rate of 1.1%. Fecal examinations were conducted on 193 individuals, with all negative. A total of 315 blood tests were performed on the mobile population, identifying 1 positive case with a blood-positive rate of 0.32%. One person received a fecal examination, with zero positive. A follow-up survey of 505 previously infected individuals revealed 5 blood-positive cases, with a positive rate of 0.99%. Fecal examinations were conducted on 15 individuals, with all negative. ConclusionIn this investigation, no local or imported sources of schistosomiasis transmission were found. However, there was a wide variety and a large number of potential sources of infection in the local area. It is necessary to actively explore regional monitoring models for schistosomiasis elimination flexibly adjust prevention and control strategies according to local conditions, achieve precise prevention and control, and consolidate the achievements of elimination.

[Objective] To explore the clinical significance of the IgG1 and IgG3 subtypes of red blood cell unexpected antibodies. [Methods] The IgG1 and IgG3 typing tests were performed on the IgG type alloantibodies of Rh, Duffy and Kidd blood group systems detected in our hospital. Additionally, IgG1 and IgG3 titers were measured and monocyte monolayer assay was performed on 12 cases of anti-E to analyze the characteristics of different IgG subtypes of anti-E. [Results] Among the 115 cases of unexpected IgG antibodies, 81 cases of monospecific antibodies were predominantly IgG1 (58.02%, 47/81); 17 cases of mixed antibodies were predominantly IgG1+IgG3 (47.06%, 16/34). In monocyte monolayer assays, the phagocytic rate and antibody titer of IgG1 and IgG3 antibodies were positively correlated, while in IgG1+IgG3 complex antibodies, it was mainly associated with IgG3, with higher antibody titers correlating with higher phagocytic rates. When the anti-E titers were 32 for all, the IgG1+IgG3 complex had the highest phagocytosis rate, followed by IgG3 alone, and IgG1 alone had the lowest phagocytic rate. [Conclusion] Monospecific antibodies among unexpected antibodies are primarily IgG1, while mixed antibodies are mainly IgG1+IgG3. The results of MMA indicate that the immune response caused by the IgG1+IgG3 complex is more severe. Therefore, when antibodies like anti-E coexist with other antibodies, even if the titer is low, the immune response may still be severe, which should be taken seriously in clinical practice.

Objective:To establish a questionnaire to assess symptom of embolization syndrome after transcatheter hepatic arterial chemoembolization (TACE) in patients with liver cancer, so as to provide a tool of assessing and managing symptom management after TACE.Methods:From March 2020 to June 2021, through literature review, qualitative interview and Delphi expert consultation, the first draft of symptom assessment questionnaire for TACE post-operative embolism syndrome was prepared. The reliability and validity of the questionnaire were tested in 200 patients with liver cancer treated by TACE in department of Liver Oncology, Zhongshan Hospital affiliated to Fudan University.Results:According to the feedback from Delphi expert consultation a draft questionnaire with 9 items of physiological symptoms and 6 items of psychological and social symptoms was formed. Item analysis showed that each item in the questionnaire had a good degree of differentiation. There was significant correlation between each item and the total score of the questionnaire. Three factors were extracted by exploratory factor analysis, naming psychosocial symptom group as factor 1, somatic discomfort symptom group as factor 2 and gastrointestinal reaction symptom group as factor 3, and the cumulative variance contribution rate was 62.592%. Spearman correlation coefficient between this questionnaire and the Anderson Symptom Assessment Scale was 0.855( P<0.05). The Cronbach α of the total questionnaire was 0.898, and. The Cronbach α of the three factors were 0.885, 0.771 and 0.870 respectively. Conclusions:The symptom assessment questionnaire of embolization syndrome after TACE in liver cancer patients prepared in this study has good reliability and validity, which can provide an evaluation basis for the symptom management of TACE.

Provirus integration site Moloney murine leukemia virus (Pim-1) is a proto-oncogene reported to be associated with cell proliferation, differentiation and survival. This study was to explore the neuroprotective role of Pim-1 in a rat model subjected to optic nerve crush (ONC), and discuss its related molecules in improving the intrinsic regeneration ability of retinal ganglion cells (RGCs). Immunofluorescence staining showed that AAV2- Pim-1 infected 71% RGCs and some amacrine cells in the retina. Real-time PCR and Western blotting showed that retina infection with AAV2- Pim-1 up-regulated the Pim-1 mRNA and protein expressions compared with AAV2-GFP group. Hematoxylin-Eosin (HE) staining, γ-synuclein immunohistochemistry, Cholera toxin B (CTB) tracing and TUNEL showed that RGCs transduction with AAV2-Pim-1 prior to ONC promoted the survival of damaged RGCs and decreased cell apoptosis. RITC anterograde labeling showed that Pim-1 overexpression increased axon regeneration and promoted the recovery of visual function by pupillary light reflex and flash visual evoked potential. Western blotting showed that Pim- 1 overexpression up-regulated the expression of Stat3, p-Stat3, Akt1, p-Akt1, Akt2 and p-Akt2, as well as βIII-tubulin, GAP-43 and 4E-BP1, and downregulated the expression of SOCS1 and SOCS3, Cleaved caspase 3, Bad and Bax. These results demonstrate that Pim-1 exerted a neuroprotective effect by promoting nerve regeneration and functional recovery of RGCs. In addition, it enhanced the intrinsic regeneration capacity of RGCs after ONC by activating Stat3, Akt1 and Akt2 pathways, and inhibiting the mitochondrial apoptosis pathways. These findings suggest that Pim-1 may prove to be a potential therapeutic target for the clinical treatment of optic nerve injury.

Objective:To investigate the risk factor of renal anemia in maintenance hemodialysis patients (MHD) and the association of N-terminal pro-brain natriuretic (NT-proBNP) level with renal anemia.Methods:Patients who received MHD for more than 3 months at Huashan Hospital affiliated to Fudan University from August 2018 to November 2018 were selected as the subjects. The patients were divided into anemia group and non-anemia group according to the hemoglobin level. The patients' general data, the laboratory examination and dialysis related data during the observation period were collected. Pearson correlation analysis was used to analyze the correlation between anemia indicators, dialysis-related indicators and blood NT-proBNP levels. Stepwise multiple linear regression analysis was used to analyze the risk factors for anemia in MHD patients.Results:A total of 160 patients with MHD were included in this study, aged (63.11±11.35) years. There were 79 males (49.4%) and 81 females (50.6%). The dialysis age was (118.01±82.32) months, hemoglobin was (110.09±13.48) g/L, and the median NT-proBNP was 3 985 ng/L. There were 73 cases (45.6%) in anemia group and 87 cases (54.4%) in non-anemic group, and NT-proBNP levels were significantly higher in anemia group than that in the non-anemia group ( t=-3.714, P<0.001). Hemoglobin levels were positively correlated with weekly dialysis time ( r=0.228) and albumin ( r=0.349), and negatively correlated with NT-proBNP levels ( r=-0.318). Hematocrit was positively correlated with weekly dialysis time ( r=0.283), serum calcium ( r=0.317), phosphorus ( r=0.264) and albumin ( r=0.513) with significance (all P<0.05). Univariate regression analysis showed that the level of ln (NT-proBNP) was negatively correlated with hemoglobin ( P<0.001). Stepwise multiple linear regression results showed that low albumin level and high NT-proBNP level were independent risk factors for renal anemia in MHD patients. Conclusions:The increase level of NT-proBNP in MHD patients is independently associated with the decrease level of hemoglobin. Low albumin level and high NT-proBNP level are risk factors for renal anemia, suggesting that the treatment of renal anemia needs to consider improving the factors such as malnutrition and high volume.

Objective To understand the distribution and change in drug resistance of common pathogens before and after the implementation of special rectification activity on antimicrobial use in 2011-2015,and provide guidance for clinical application of antimicrobial agents.Methods Antimicrobial use in hospitalized patients and pathogens isolated from patients in a hospital from 2011 to 2015 were collected,changing trend of resistance rates of major pathogens to commonly used antimicrobial agents was analyzed.Results From 2011 to 2015,antimicrobial utilization rate in hospitalized patients dropped from 75.84%to 37.35%,antimicrobial use density decreased from 59.53 per 100 patient days to 33.63 per 100 patient days,both showed a downward trend(both P<0.05).A total of 10 091 strains of pathogens were isolated,2 338(23.17%)of which were gram-positive bacteria,7 110(70.46%)were gram-negative bacteria,and 643(6.37%)were fungi.The top five pathogens were Escherichia coli(20.85%),Klebsiella pneumoniae(15.90%),Pseudomonas aeruginosa(11.70%),Staphylococcus aureus(7.35%),and Acinetobacter baumannii(6.82%).Resistance rates of major pathogens to commonly used antimicrobial agents decreased year by year(P<0.05),resistance rates of Escherichia coli and Klebsiella pneumoniae to piperacillin/tazobactam,cefoxitin,and amikacin declined most obviously(all<4%in 2015);compared with Acinetobacter baumannii,Pseudomonas aeruginosa had higher sensitivity to commonly used antimicrobial agents,resistance rates to piperacillin/tazobactam,cefoperazone/sulbactam,ceftazidime,cefepime,amikacin,and ciprofloxacin decreased obviously,resistance rate to above antimicrobial agents was <20%,to carbapenems was higher than other commonly used antimicrobial agents.Resistance rates of Acinetobacter baumannii to amikacin,levofloxacin decreased most obviously,to meropenem and imipenem increased obviously,in 2015 were both above 50%.Resistance rate of Staphylococcus aureus to fluoroquinolones declined most obviously(<2%),vancomycin-resistant strains were not found.Conclusion After the implementation of special rectification activity,resistance rates of common pathogens decreased with the decline of antimicrobial use,rational use of antimicrobial agents may be related to delaying bacterial resistance.

Objective To explore the application of A-V impulse foot pump in patients with lumbar spine surgery to prevent lower extremity deep venous thrombosis. Methods A total of 139 patients with spinal lesions who took spinal surgery treatment from April 2015 to March 2016 were divided into experimental group (69 cases) and control group (70 cases) by random digits table method. Control group was given normal nursing instruction, and the person who had negative results of B ultrasonic examination in experimental group was accepted physical therapy with A-V impulse foot pump. The patients got secondary ultrasound or CT examination who had the deep venous thrombosis symptoms and/or highly suspected deep venous thrombosis in order to further confirmed, then calculated the incidence rate of two groups with deep venous thrombosis. Results There were 4 cases of 139 patients who got deep venous thrombosis in 2-6 days of postoperative, 1 case in experimental group, 3 case in control group, compared with control group, patients who used A-V impulse foot pump had lower risk of deep venous thrombosis, but there was no significant difference (P>0.05). The operation time, body mass index were (5.00 ± 0.82) h , (30.54 ± 3.93) kg/m2 in patients with deep venous thrombosis and (3.16 ± 0.66) h, (24.90 ± 2.62) kg/m2 in patients without deep venous thrombosis, and there were significant differences(t=5.44, 4.19, P<0.01). Conclusions The application of A-V impulse foot pump has positive significance to prevent the happening of deep venous thrombosis for patients who took spinal surgery, and it is worth to be popularized and applied in clinic.
