Objective: To retrospectively analyze the clinical data of 474 newborns with hyperbilirubinemia, and to investigate the clinical characteristics of hyperbilirubinemia caused by ABO hemolytic disease of the fetus and newborn (ABO-HDFN) and factors influencing the phototherapy duration. Methods: A total of 474 neonates with hyperbilirubinemia treated in the First Hospital of Lanzhou University from January 2019 to January 2023 were enrolled. Blood type identification and the standard serological tests (direct antiglobulin test, serum free antibody test, and antibody elution test) were performed for all neonates. Baseline clinical data were collected and analyzed. According to the results of the hemolysis tests, neonates were divided into hemolytic jaundice group and non-hemolytic jaundice group. Clinical indicators, including hemoglobin levels, length of hospital stay, and phototherapy duration, were compared between the two groups. A multiple linear regression model was used to explore clinical factors influencing the duration of phototherapy. Results: Among the 474 neonates with hyperbilirubinemia, 354 were diagnosed with ABO-HDFN (hemolytic group), while 120 were without ABO-HDFN (non-hemolytic group). The incidence of ABO-HDFN in neonates with blood type A (55.93%, 198/354) was significantly higher than those with blood type B (44.07%, 156/354) (P<0.05). Furthermore, neonates born to multiparous women had a significantly higher ABO-HDFN incidence (81.56%, 146/179) than first-born neonates (70.51%, 208/295) (P<0.05). Neonates in the hemolytic group had significantly lower hemoglobin levels (170.67±21.86 g/L vs 178.99±22.05 g/L, P<0.001), lower red blood cell counts (4.66±0.63×10 /L vs 4.89±0.59×10 /L, P<0.05), and lower hematocrit (50.05±6.56% vs 52.61±6.75%, P<0.05) compared to the non-hemolytic group. Additionally, the hemolytic group had significantly longer hospital stays (6 [5, 9] days vs 6 [4, 8] days), longer phototherapy duration (62 [38, 84.25] h vs 53 [34.25, 64.77] h), and higher frequency of jaundice episodes (9 [7, 13] times vs 8 [6, 12] times] compared to the non-hemolytic group (all P<0.05). Regression analysis indicated that a positive indirect Coombs test and multiparity were independent risk factors associated with prolonged phototherapy duration (P<0.05). Conclusion: ABO incompatibility is the leading cause of hemolytic disease in neonates, particularly in cases where the mother has blood type O and the neonate has blood type A. In such cases, close monitoring of bilirubin levels is strongly recommended. Multiparous pregnancies increase the risk of alloimmune hemolysis. Therefore, neonates born to multiparous women may require more frequent bilirubin monitoring and appropriate prenatal interventions when necessary. Additionally, changes in indicators such as hemoglobin level and red blood cell count should be closely monitored as early warning indicators for hemolytic anemia and bilirubin elevation.

Although small in size, the eyeballs are extremely important in function, and are delicate and complex in structure. With the wide application of acupuncture for eye diseases and the high frequency of use of intra-orbital points, the incidence of acupuncture accidents increases accordingly in treatment. We reported two recent accident cases, retinal tear and ciliochoroidal detachment that occurred during the regular operation of acupuncture and acupoint injection at intra-orbital points, in order to strengthen people's awareness of acupuncture accidents caused by acupuncture at the points in the orbital region, and enhance the sound development and comprehensive promotion of acupuncture in treatment of eye diseases.

Objective:To establish an antibody expression system to reduce the antibody-dependent enhancement (ADE) effect of target antibody.Methods:Site-directed mutagenesis was used to mutate the 234 and 235 sites of the Fc region of the mammalian cell antibody expression vector-L234A and L235A to establish the antibody expression vector pFRT-IgG1κ-FcM. An antibody Wt-WNV with significant ADE effect obtained in previous work was selected and expressed by the pFRT-IgG1κ-FcM system to obtain mutant antibody FcM-WNV. The binding ability of FcM-WNV to target antigen West Nile virus envelope protein-DⅢ (WNV E-DⅢ) was detected by ELISA, and the its binding ability to human high-affinity IgG Fc receptor hFcγRⅠ (hCD64 ) was analyzed by flow cytometry. The neutralizing activity of FcM-WNV in vitro was detected by pseudovirus infection of host cells (BHK21 and K562). Results:The expression levels of FcM-WNV and Wt-WNV were comparable, and FcM-WNV could recognize and bind to WNVE-DIII in a concentration-dependent manner. Compared with Wt-WNV, the binding ability of FcM-WNV to hCD64 was significantly weakened, showing a significant decrease in fluorescence intensity. Consistent with the previous experimental results, Wt-WNV at a concentration of 5 μg/ml significantly enhanced the infection of K562 by WNV pseudovirus, while FcM-WNV at a concentration of 5 μg/ml could effectively block pseudovirus infection in both K562 and BHK21 cells.Conclusions:The established antibody expression system can effectively reduce the ADE effect of the target antibody.

Objective:To establish an in vivo infection model of West Nile virus (WNV) pseudovirus and evaluate the neutralizing activity of antibody WNV-XH1.Methods:A stable cell line that can package the WNV pseudovirus was established in the early stage to prepare the pseudovirus supernatant. The supernatant was concentrated and infected BHK21 cells to detect the titer of the pseudovirus. After intraperitoneal injection of the pseudovirus into C57BL/J mice, bioluminescence imaging was performed to observe the infection status of the pseudovirus in the mice. After simultaneous infection, blood was collected and ELISA was used to detect NS1 levels in mouse serum. The in vivo functional activity of antibody WNV-XH1 was evaluated using the established mouse infection model.Results:Fluorescence was detected in C57BL/J mice infected with WNV pseudovirus, and the NS1 levels in the peripheral blood serum of mice infected with pseudovirus were significantly higher than those of non infected mice (1.453±0.09vs0.305±0.018). After intravenous administration of WNV-XH1 antibody before the attack, the fluorescence signal in the mice decreased and the serum NS1 level decreased (0.384±0.015).Conclusions:A successful in vivo infection model of WNV pseudovirus was established, and it was confirmed that the antibody WNV-XH1 had a protective effect against WNV pseudovirus infection in vivo.
