Objective: To report the antibody identification, blood management during pregnancy and the monitoring process of fetal hemolytic disease of fetus and newborn (HDFN) in a pregnant woman with a history of blood transfusion and pregnancy who developed anti-Jr . Methods: Saline tube technique and anti-human globulin technique were used for maternal blood typing, unexpected antibody screening and identification, as well as for determining antibody titer and IgG subclasses. PCR-SSP was employed for genotyping of 18 blood group systems. Next-generation sequencing (NGS) was utilized for gene sequencing of 38 blood group systems. Sanger sequencing was applied to verify rare blood group mutations detected by NGS and to investigate the corresponding rare blood group genes in family members. Blood preparation was achieved through anemia management in prenatal clinics and autologous blood collection during pregnancy. The newborn underwent the three primary tests for HDFN and plasma IgG subclass testing. Results: The pregnant woman's blood type was B, RhD positive, with a positive unexpected antibody screen, and the antibody identification pattern was consistent with a high-frequency antigen antibody. Gene sequencing revealed a homozygous ABCG2 c.376C>T mutation in the woman, resulting in the Jr(a-) phenotype, and anti-Jr antibody was present in her plasma. No compatible Jr(a-) blood was found among family members. The maternal anti-Jr IgG titer remained stable at 256 during pregnancy, with no detectable IgG1 or IgG3 subclasses against the Jr antigen. A total of 800 mL of autologous blood was collected in two stages during pregnancy. The newborn was B, RhD positive, Jr(a+), with a positive unexpected antibody screen (anti-Jr ). IgG subclass typing detected no IgG1 or IgG3. The direct antiglobulin test was positive, while the acid elution test was negative. Conclusion: The combination of serology and blood group genetic analysis provides a diagnostic basis for identifying antibodies to high-frequency antigens. Managing perinatal anemia and implementing staged autologous blood storage can secure blood supply for the perioperative period. IgG antibody subclass typing offers a reference for clinical assessment and prevention of HDFN.

Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

Objective To explore the correlation of body mass index,urinary protein and tumor necrosis factor-like weak inducer of apoptosis(sTWEAK)during pregnancy with the severity of preeclampsia and pregnancy outcome.Methods A total of 63 patients with preeclampsia who were examined in Xingtai People's Hospital from April 2022 to April 2023 were enrolled in the study,33 patients with mild preeclampsia were included in the mild group and 30 patients with severe preeclampsia were included in the severe group.Physi-cal characteristics,urinary protein and sTWEAK levels between the groups were recorded,and the patients were followed up to explore the correlation with pregnancy outcome.Results The systolic and diastolic blood pressure of patients in the mild group were lower than those in the severe group,and the plasma albumin was higher than that in the severe group(P＜0.05).There was no statistically significant difference in pre preg-nancy weight and pre pregnancy body mass index between the mild and severe groups of patients(P＞0.05).The delivery weight and weight gain during pregnancy in the mild group were lower than those in the severe group(P＜0.05).The 24-hour urinary protein quantification in the mild group was lower than that in the se-vere group,and the sTWEAK expression level was higher than that in the severe group(P＜0.05).The pre pregnancy weight,pre pregnancy body mass index,delivery weight,and weight gain during pregnancy in the good pregnancy outcome group were all lower than those in the adverse pregnancy outcome group(P＜0.05).The 24-hour urinary protein quantification in the good pregnancy outcome group was lower than that in the adverse pregnancy outcome group,and the sTWEAK expression level was higher than that in the adverse pregnancy outcome group(P＜0.05).Receiver operating characteristic(ROC)curve analysis revealed that the area under the curve(AUC)of pre pregnancy body mass index,pre pregnancy weight,delivery weight,gestational weight gain,24-hour urinary protein quantification,and sTWEAK expression levels for predicting adverse pregnancy outcomes in patients were 0.906,0.690,0.919,0.664,0.908,and 0.793,respectively.The AUC for predicting adverse pregnancy outcomes in patients by combining pre pregnancy body mass index,de-livery weight,24-hour urinary protein quantification,and sTWEAK expression level was 0.932.Conclusion Body mass index,urinary protein and sTWEAK levels during pregnancy are closely associated with the severity of pre-eclampsia and pregnancy outcomes,and these indicators may help identify high-risk pregnant women early and take appropriate interventions to improve pregnancy outcomes.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.

Objective To explore clinical value of the expression levels of cell surface transmembrane glycoprotein molecule 44(CD44)mRNA,cell surface transmembrane glycoprotein molecule 24(CD24)mRNA,and protein in the placenta of severe preeclampsia(SPE)patients.Methods The SPE patients who were delivered by cesarean section in the Second People's Hospital of Liaocheng from June 2019 to June 2022 were further divided into 45 patients in early onset SPE group(gestational age≤34 weeks)and 55 patients in late onset SPE group(gestational age＞34 weeks)according to the different gestational age.The control group consisted of 100 normal cases in the same period.The expression of CD44 and CD24 in placenta of SPE patients was detected by fluorescent quantitative PCR and immunohistochemistry,Pearson method was used to analyze the difference of their expression levels and their correlation with the clinical characteristics of SPE disease,and multivariate logistic regression was used to analyze the influencing factors of SPE.Results Compared with the control group,the expression levels of CD44 mRNA(0.55±0.12 vs 1.02±0.33)and CD24 mRNA(0.68±0.19 vs 1.05±0.11)in SPE placental tissues decreased significantly,the differences were statistically significant(t=13.385,16.853,P＜0.05).The immunohistochemical staining results showed that CD44 and CD24 were mostly negative or weakly positive in the SPE group placental tissue,while they were mostly positive in the control group,the positive rates of CD44 and CD24 in the SPE placental tissue were lower than those in the control group,and the differences were statistically significant(χ2=9.696,14.346,P＜0.05).Compared to the early onset SPE group,the expression levels of CD44(0.65±0.17 vs 0.42±0.11)and CD24(0.77±0.23 vs 0.58±0.13)mRNA in placental tissue of late onset SPE were higher,and the differences were statistically significant(t=7.830,4.932,P＜0.05).Compared with the control group,the BMI,systolic blood pressure,diastolic blood pressure,urinary protein,Cr,LDH and BUN were significantly increased in SPE group(t=5.360～30.241,all P＜0.05).In SPE group,the gestational age was earlier,the MPV and ALB were lower,the newborn's birth length was shorter,and the body weight than control group,the differences were statistically great(t=3.232～11.109,all P＜0.05).The expression of CD44 and CD24 in SPE placenta was positively correlated(r=0.698,P＜0.05),the expression of CD44 in SPE placenta was positively correlated with CD24,gestational week of delivery,MPV and neonatal birth length(r=0.611,0.639,0.612,0.465,all P＜0.05),and was negatively correlated with systolic blood pressure,urinary protein and LDH(r=-0.604,-0.569,-0.593,all P＜0.05).The expression of CD24 was positively correlated with gestational age,MPV and newborn birth length(r=0.605,0.584,0.640,all P＜0.05),and was negatively correlated with systolic blood pressure,urinary protein and LDH(r=-0.637,-0.593,-0.561,all P＜0.05).The results of logistic regression analysis showed that MPV(95％CI:1.429～4.350),urinary protein(95％CI:1.529～2.709),and LDH(95％CI:1.425～3.932)were all independent risk factors for SPE(all P＜0.05).High levels of CD44(95％CI:0.561～0.940)and CD24(95％CI:0.495～0.814)were independent protective factors for SPE(P＜0.05).Conclusion The low expression levels of CD44 and CD24 in placenta of SPE patients are independent protective factors of SPE,which can provide direction for the follow-up treatment of SPE.

Objective:To evaluate the effect of Kuntai capsules combined with progestin-primed ovarian stimulation (PPOS) protocol on the ovarian response, laboratory parameters and embryo transfer outcomes of expected poor ovarian response (POR) patients undergoing invitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods:A retrospective cohort study was performed at Center for Reproductive Medicine, Jiangxi Maternal and Child Health Hospital from June 2020 to July 2023. A total of 1 733 expected POR patients were enrolled and divided into the PPOS only group (control group) and the Kuntai capsules combined with PPOS regimen group (trial group). After a 1∶1 propensity score matching, 423 cases were included in each group. Further analyses and comparisons were made between the two groups, concerning the ovarian stimulation outcomes, embryo laboratory parameters and pregnancy rates after the first frozen-thawed embryo transfer cycles. The primary outcome measure was the number of oocytes retrieved.Results:No statistically significant difference was found in baseline characteristics after matching between the two groups (all P>0.05). Compared with control group, the number of oocytes retrieved did not differ significantly in the trial group ( P=0.295). The level of luteinizing hormone (LH) on the trigger day [3.3 (2.2, 5.0) U/L], the number of available blastocysts formed [1 (0, 1)] and the available blastocyst formation rate [46.2% (85/184)] in the trial group were significantly higher than those in control group [2.9 (1.9, 4.5) U/L, P=0.004; 0 (0, 1), P=0.034; 30.0% (48/160), P=0.002]. However, there were no significant differences in the duration and dosage of gonadotropin used, progesterone and estradiol levels on the trigger day, incidence of premature LH surge, number/rate of fertilized oocytes, number/rate of cleaved embryos, number/rate of high-quality embryos, as well as rate of unavailable embryos (all P>0.05). Compared with control group, the trial group demonstrated comparable implantation rate, clinical pregnancy rate, early miscarriage rate, ongoing pregnancy rate and live birth rate after the first frozen-thawed embryo transfer cycles (all P>0.05). Conclusion:Compared with the PPOS only regimen, the combination of Kuntai capsules and PPOS did not increase the number of oocytes retrieved but could increase the number and rate of available blastocysts formed in expected POR patients.

Objective This study aims to compare the accuracy of self-developed universal implant guide(SDG),3D printed digital guide(DG),and free hand(FH)simulated implantation in the posterior tooth area of dental models.Methods Ten junior dentists were selected to place three implants in the 35,37,and 46 tooth sites of the mandibular models(35,36,37,and 46 missing teeth)by using SDG,DG,and FH,and the process was repeated again to take the av-erage value.Cone beam computed tomography(CBCT)was used to evaluate the global coronal deviation,global apical deviation,depth deviation,and angular deviation between the actual position and preoperative planned position.Re-sults The coronal deviation and apical deviation of the three implant sites in the SDG group were not significantly dif-ferent from those in the two other groups(P>0.05).The depth deviation and angular deviation in the SDG group were smaller than those in the DG group(P<0.05)and FH group(P<0.05),respectively.All deviations at site 37 in the SDG group were not different from those at site 35(P>0.05),while the depth and angular deviation at site 37 in the DG group were higher than those at site 35(P<0.05).Conclusion The precision of the self-developed universal dental im-plant guide can meet the requirements of clinical posteri-or implantation.
