With the accelerating process of population aging, binocular vision disorders have become increasingly prevalent, posing new challenges for both social aging strategies and ophthalmic clinical practice. Non-strabismic binocular vision anomalies(NSBVAs)are notably prevalent among elderly populations; however, current research predominantly focuses on the abnormality rates derived from individual binocular vision clinical tests, while data on the actual prevalence based on comprehensive diagnostic criteria remain limited. This review synthesizes existing scientific literature to provide a concise yet comprehensive overview of the prevalence, risk factors, and clinical diagnostic methods of NSBVAs in pre-presbyopic and presbyopic populations, with an in-depth examination of age-related changes in binocular vision function among older adults. By integrating and comparing analyses of the correlations between age and various binocular vision parameters, this review aims to enhance understanding of age-related binocular vision dysfunction and establish a theoretical foundation for developing targeted diagnostic and therapeutic approaches. Ultimately, these insights could contribute to improved visual performance and life satisfaction in elderly individuals.

Objective To elucidate the prediction ability of monocyte monolayer assay(MMA)used in hemolytic dis-ease of fetus and newborn(HDFN)caused by IgG anti-M.Methods Plasma from eight pregnant women containing IgG an-ti-M were collected,and were divided into two groups(4 cases with HDFN,with severe clinical symptoms such as fetal hy-drops,and 4 cases without HDFN)according to the clinical outcomes.M antigen positive cells were sensitized with dithioth-reitol(DTT)treated plasma from eight pregnant women respectively.MMA was performed by coincubation with monocytes and sensitized M cells,along with negative and positive control set up.T-test was conducted to compare the difference in phagocytic efficiency between two groups.Results The phagocytic efficiency in group with HDFN were 15.37%,13.05%,9.17%and 24.50%respectively,with the mean value of 15.52%,while the group without HDFN were 8.74%,11.07%,5.12%and 6.23%respectively,with the mean value of 7.79%.There was no significant difference in phagocytic efficiency between two groups(P>0.05).The mean values of both groups were not significantly different from the negative control(P>0.05),but both were significantly lower than positive control(P<0.05).Conclusion The low phagocytic efficiency couldn't convince that the MMA is an effective predictor for the HDFN caused by IgG anti-M,indicating that another mech-anism might be responsible for it rather than monocyte phagocytosis.The assessment of the peak systolic velocity in middle cerebral artery of the fetal should be considered in the management for pregnant women who produce IgG anti-M to estimate the situation of fetal anemia.

【Objective】 To identify the specificity of alloantibody against high-frequency antigens in one case suffering with severe hemolytic diseases of the fetus and newborn (HDFN) and to screen for matching blood for transfusion. 【Methods】 The HDFN test and the antibody serological identification tests in the mother were performed. Several common high frequency antigens of maternal red blood cells (RBCs) were determined. IgG subtype coated on the RBCs of the newborn was determined. The phagocytic efficiency of the antibody was tested using the monocyte phagocytosis of sensitized erythrocyte by flow cytometry in vitro. Sanger sequencing of DI gene was performed in the mother, father and mother’s brother. The diluted maternal plasma was used for large scale screening of matching blood using IAT in Coomb’s gel card. 【Results】 Di(b-) phenotype was identified in the mother of the newborn and anti-Di^b (titer: 512) related HDN was detected in the newborn. IgG1 and IgG2 subtypes of anti-Di^b were detected and the rate of monocyte phagocytosis was 88.83%(74.7/84.09). The compatible blood was not detected in the maternal relatives. Subsequently, the newborn received the matching RBCs of two Di(b-) donors identified from 5 520 blood donors and discharged from the hospital. We screened out 17 Di(b-) donors out of 51 334 blood donors, indicating that the distribution frequency of Di(b-) among blood donors in Guangzhou was about 0.033% (17/51 334). 【Conclusion】 By serology and molecular biology methods, the newborn was identified with HDFN caused by anti-Di^b, and an effective large-scale screening method for Di (b -) rare blood types was established to find matching blood, which supported the establishment of rare Di(b-) blood database.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the relationship between serum cathepsin B(CTSB)and long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1(lncRNA MALAT1)levels and disease severity in patients with sepsis-associated acute kidney injury(SA-AKI)and their prognostic value.Methods A total of 80 patients with SA-AKI admitted to Deyang People's Hospital from January 2021 to January 2023 were selected as the SA-AKI group,and 80 patients with simple sepsis in the same period were selected as the simple sepsis group.According to the severity of the disease,SA-AKI patients were divided into stage 1(22 cases),stage 2(27 cases),and stage 3(31 cases).According to the 28 d clinical outcome,the pa-tients were divided into death group(35 cases)and survival group(45 cases).Enzyme-linked immunosorbent assay and real-time fluorescence quantitative PCR were used to detect serum CTSB and lncRNA MALAT1 levels.Multivariate Logistic regression analysis was used to analyze the influencing factors of poor prognosis in patients with SA-AKI.Receiver operating characteristic curve was used to analyze the predictive value of se-rum CTSB and lncRNA MALAT1 levels for death in patients with SA-AKI.Results Compared with the sim-ple sepsis group,the serum levels of CTSB and lncRNA MALAT1 were significantly increased in the SA-AKI group(P＜0.05).The serum levels of CTSB and lncRNA MALAT1 in patients with stage 1,stage 2,and stage 3 SA-AKI were increased in turn(P＜0.05).The 28 d mortality of the 80 patients was 43.75％.AKI stage 3,acute physiology and chronic health evaluation Ⅱ score,sequential organ failure assessment score,ele-vated blood lactate,CTSB and lncRNA MALAT1 were independent risk factors for death in patients with SA-AKI(P＜0.05).The area under the curve of serum CTSB combined with lncRNA MALAT1 for predicting the death of patients with SA-AKI was 0.894,which was higher than 0.797 and 0.793 predicted by serum CTSB or lncRNA MALAT1 levels alone(P＜0.05).Conclusion The increased levels of serum CTSB and ln-cRNA MALAT1 in patients with SA-AKI are closely related to the aggravation of the disease and poor prog-nosis.Serum CTSB combined with lncRNA MALAT1 levels have a high predictive value for the prognosis of patients with SA-AKI.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Objective:To explore the application effect of "connections, concepts, concrete practice and conclusions (4C)" teaching method combined with two-way evaluation method in nursing teaching of gastrointestinal surgery, so as to provide reference for personnel training and quality control of practice.Methods:A historical controlled study was conducted to prospectively include the nursing interns received by the Department of Gastrointestinal Surgery of the hospital from May 2020 to May 2022 as the subjects of this study. The interns were divided into the control group (64 interns from May 2020 to May 2021) and the research group (93 interns from June 2021 to May 2022) according to the order of admission of nursing interns. The control group was taught by traditional nursing teaching method, while the research group was taught by "4C" teaching method combined with two-way evaluation method. The scores of theoretical knowledge and operation of nursing students in the two groups were compared after 6 weeks of practice. The self-directed learning ability of nursing students in the two groups was compared before and after 6 weeks of practice [Chinese version of self-rating scale of self-directed learning (SRSSDL)]. The evaluation of teaching quality between two groups of nursing students were compared. SPSS 25.0 was used for t-test and Chi-square test. Results:One person in the control group voluntarily quit the internship, and two in the observation group voluntarily quit the internship. Finally, 63 people in the control group and 91 people in the research group entered the study. There was no statistical significant difference between the two groups in baseline data ( P>0.05). At 6 weeks of practice, the scores of theoretical knowledge (87.96±4.62) and operation (92.60±4.25) in the study group were higher than those in the control group [(86.02±4.53) and (88.27±4.31)] ( P<0.05). At 6 weeks of practice, the total scores of learning awareness, learning behavior, learning strategies, learning evaluation, interpersonal skills and self-directed learning ability of the two groups were higher than those before practice, and the study group was higher than the control group ( P<0.05). After 2 weeks, 4 weeks and 6 weeks of practice, the scores of the two groups of nursing students in evaluating the teaching quality of the teachers increased gradually compared with that of the first week of practice ( P<0.05). Conclusion:The "4C" teaching method combined with the two-way evaluation method in the nursing teaching of gastrointestinal surgery can improve the nursing students' theoretical knowledge, practical operation ability and self-directed learning ability, and is conducive to the improvement of teaching quality.

【Objective】 To solve the difficulty of RhD blood group typing in a patient with double population(DP) of red blood cells for RhD antigen by serological and genotyping analysis. 【Methods】 Separation of the two populations of red blood cells of the patient was performed using capillary centrifugation method. ABO, RhD and RhCE typing, direct anti-human globulin test (DAT), irregular antibody screening, antibody identification and blood crossmatching of the patient were conducted using the standard serological methods. The hybrid Rhesus zygosity analysis of the RHD gene was performed by PCR-RFLP method. RHD and RHCE genotype of the patients were identified by PCR-SSP method. 【Results】 The patient was B type but with DP of red blood cells for RhD, Rhc and RhE antigens. DAT of the patient was positive and the alloanti-D was detected in serum. The RHD zygosity was D-/D- homozygote. PCR-SSP testing showed the RHD gene deletion (RHD * 01N. 01/01N.01 genotype) and Ccee of RHCE genotype in the patient, which was consistent with RHD zygosity analysis. 【Conclusion】 This is a special case with D-negative phenotype which was wrongly detected as D-positive type after D-positive red blood cells transfusion in emergency. When the DP of red cells for D antigen encountered like this case, the RhD typing can be accurately determined by using RHD genotyping analysis to provide strong evidence to the clinical blood transfusion.

The main clinical phenotypes, imaging features and genetic test results of a child with Joubert syndrome treated in Shenzhen Children′s Hospital in July 2020 were analyzed retrospectively, and the literature on Joubert syndrome was summarized.The main manifestations of the protester during infancy were respiratory abnormalities and developmental retardation.The brain magnetic resonance imaging (MRI) showed a " molar sign" , which was consistent with the diagnosis of Joubert syndrome.Genetic testing suggested that the protestor carried complex heterozygous variations of KIAA0586 gene.Two variants were not reported previously, one of which was synonymous mutation.The child is the first case of Joubert syndrome caused by KIAA0586 gene in China.Joubert syndrome is a rare congenital brain development malformation characterized by high clinical heterogeneity and MRI molar signs.It may involve multiple systems.Early identification and intervention can improve outcomes.
