Objective: To establish a prenatal non-invasive method for combined detection of fetal ABO, RhD, and RhCE blood group genotypes based on fluorescence quantitative PCR (FQ-PCR) technology, and to evaluate its clinical value in the early prenatal diagnosis of hemolytic disease of the fetus and newborn (HDFN). Methods: A total of 200 high-risk singleton pregnant women who underwent prenatal examinations in our hospital from January 2022 to December 2024 were prospectively enrolled. They were divided into four groups: the ABO incompatibility group (n=100), the RhD incompatibility group (n=50), the RhCE incompatibility group (n=50), and the control group (n=200). FQ-PCR technology was used to detect cell-free fetal DNA (cff-DNA) in maternal plasma, targeting the ABO system (261delG, 796C>A), exons 5/7 of the RHD gene, and the key loci of RhCE system (C/c, E/e). After delivery, the blood group of newborn was verified by serological testing of umbilical cord blood., and the hemolysis panel tests (direct antiglobulin test, free antibody test, and antibody release test) were performed to evaluate the detection consistency and identify high-risk factors. Results: The detection coincidence rates for ABO, RhD, and RhCE blood groups were 98.0% (98/100), 100.0% (50/50), and 96.0% (48/50), respectively. The incidence of HDFN in the ABO incompatibility group was 69.0% (69/100), which is significantly higher than that in the RhD incompatibility group (10.0%, 5/50) and the RhCE incompatibility group (2.0%, 1/50). Multivariate analysis identified maternal blood type O (OR=3.021), maternal RhD-negative (OR=5.253), and maternal age ≥35 years (OR=1.950) as independent risk factors for HDFN (all P<0.05). Conclusion: Prenatal non-invasive combined detection of multiple blood group antigen genotypes can significantly improve the efficiency of early diagnosis of HDFN and provide accurate early warning for high-risk pregnant women.

Objective:To explore the clinical values of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), carbohydrate antigen 199 (CA199), carbohydrate antigen 724 (CA724) and gastrin 17 (G-17) detections in the early diagnosis of gastric cancer patients.Methods:A retrospective case-control study was conducted. A total of 120 patients with gastric diseases who were admitted to General Hospital of Xuzhou Mining Group from January 2019 to December 2021 were selected. According to the pathological results of gastroscopy examination, the patients were divided into gastric ulcer group (23 cases), atrophic gastritis group (58 cases) and early gastric cancer group (39 cases). The healthy control group consisted of 30 healthy individuals who underwent physical examination during the same period. All participants were detected for serum levels of CEA, CA125, CA199, CA724, and G-17. The levels of various indicators in each group were compared. Using the pathological results of gastroscopy as the gold standard, the receiver operating characteristic (ROC) curve was used to analyze the efficacy of various indicators in distinguishing early gastric cancer from healthy individuals, gastric ulcer and atrophic gastritis.Results:The serum levels of CA125 [ M ( Q1, Q3)] [19.94 (8.29, 22.99) U/ml vs. 6.03 (4.07, 10.48) U/ml, 7.49 (4.96, 12.19) U/ml, 7.54 (6.20, 11.91) U/ml], CA199 [32.09 (15.68, 41.97) U/ml vs. 19.19 (10.01, 30.05) U/ml, 21.00(16.01, 32.71) U/ml, 18.95 (13.90, 32.76) U/ml], CA724 [19.55 (3.91, 26.25) U/ml vs. 4.61 (3.06, 5.24) U/ml, 4.09 (3.37, 5.00) U/ml, 4.88 (3.92, 5.46) U/ml] and G-17 [21.01 (14.67, 24.00) pmol/L vs. 11.80 (10.07, 16.58) pmol/L, 12.74 (11.09, 14.69) pmol/L, 12.08 (8.40, 15.10) pmol/L] in the early gastric cancer group were higher than those in the gastric ulcer group, atrophic gastritis group and healthy control group, and the differences were statistically significant (all P < 0.05). The CEA level in the early gastric cancer group, gastric ulcer group and atrophic gastritis group was all higher than that in the healthy control group [4.38 (3.22, 7.56) ng/ml, 4.51 (3.37, 5.51) ng/ml, 4.49 (4.13, 5.09) ng/ml vs. 3.95 (2.16, 4.44) ng/ml], and the differences were statistically significant (all P < 0.05). ROC curve analysis showed that among all indicators, the area under the curve (AUC) of G-17 for distinguishing early gastric cancer from healthy individuals was the largest [0.825 (95% CI: 0.728-0.922)], the optimal critical value was 18.21 pmol/L, and the specificity was the highest (96.7%); the AUC of CA125 and CA724 was also relatively high, with values of 0.768 (95% CI: 0.653-0.884) and 0.744 (95% CI: 0.622-0.866), respectively, and the optimal critical values were 15.41 and 39.60 U/ml, respectively, with the corresponding sensitivities of 71.8%, which was the highest among several indicators. Among all indicators, CA125 had the largest AUC for distinguishing early gastric cancer from gastric ulcer, which was 0.829 (95% CI: 0.729-0.930), with an optimal critical value of 11.60 U/ml, and the corresponding sensitivity was also the highest (74.4%); the AUC of CEA and CA724 was 0.534 (0.391-0.677) and 0.786 (0.668-0.903), respectively; the optimal critical values were 7.20 ng/ml and 6.34 U/ml, respectively; the corresponding specificity was 100.0%. Among the various indicators, the AUC of G-17 for distinguishing early gastric cancer from atrophic gastritis was the largest [0.813 (95% CI: 0.710-0.915)]. The specificity of each indicator at the optimal critical value was relatively high (≥ 94.8%), among which the optimal critical values of CEA and CA125 were 7.170 ng/ml and 15.55 U/ml, respectively, with the corresponding specificity of 100.0%; the AUC of CA724 was 0.783 (95% CI: 0.671-0.895), the optimal critical value was 6.40 U/ml, and the corresponding sensitivity was 71.8%, which was the highest among the several indicators. Conclusions:CEA, CA125, CA199, CA724, and G-17 have high sensitivity and detection rate in the differential diagnosis of early gastric cancer, gastric ulcer and atrophic gastritis, and have certain clinical values in the diagnosis of early gastric cancer and potential for clinical auxiliary diagnosis.

ObjectiveTo explore the pathological mechanism-syndrome-treatment patterns of approved Chinese patent medicines （CPMs） that treat collateral disorders， providing a reference for the principle of "treating different diseases with the same therapy" in collateral pathology. MethodsCPMs that apply treatment strategies based on collateral disorders were identified from the Pharmacodia database by extracting information from the "efficacy" or "indications" sections of drug package inserts. A database was established to extract the names and compositions of the CPMs， as well as their indications， related traditional Chinese medicine （TCM） symptoms， disease locations （affected areas）， and pathological factors. Frequency statistics were performed. Using the Apriori algorithm， an association rule analysis was conducted on CPMs and disease-location combinations related to the top three most frequent pathological factor combinations. Core formulas for these combinations were identified and analyzed through drug network analysis and MCODE module clustering. ResultsA total of 660 CPMs targeting collateral disorders were retrieved， involving 299 indications， 323 TCM symptoms， 21 disease locations， 19 pathological factors， and 124 pathological factor combinations. The most frequent pathological factor combinations were blood stasis （involved in 109 CPMs， 16.52%）， exogenous wind （外风） -cold-dampness （involved in 43 CPMs， 6.52%）， and qi deficiency-blood stasis （involved in 42 CPMs， 6.36%）. Analysis of the core formulas for these combinations revealed common ingredients such as Honghua （Carthami Flos）， Chuanxiong （Chuanxiong Rhizoma）， Danggui （Angelicae Sinensis Radix）， and Dilong （Pheretima）. ConclusionCollateral disorders involve a wide range of pathogenesis and represent a fundamental mechanism in the onset and development of various diseases， characterized by obstruction and stagnation. The primary therapeutic principle is unblocking of the collaterals. Blood stasis obstructing the collaterals is the core pathological basis， and the strategy of activating blood circulation and resolving stasis to unblock the collaterals should be central to the treatment. The core medication pattern involves combining blood-activating and stasis-resolving herbs with insect-derived medicinals that unblock collaterals. Exogenous wind is often the initiating patholo-gical factor in colla-teral disorders， and the appropriate addition of wind-dispelling herbs can enrich the treatment strategies for such conditions.

Objective:To analyze the influencing factors of mood state of common rheumatic (rheumatoid arthritis; systemic lupus erythematosus; ankylosing spondylitis) patients and find out the common characteristics of patients with negative emotions, so as to identify and treat rheumatic patients with anxiety and depression in clinical practice.Methods:A total of 205 patients with rheumatism (83 with rheumatoid arthritis, 74 with systemic lupus erythematosus, 48 with ankylosing spondylitis) admitted to the Shandong Provincial Hospital Affiliated to Shandong University from April to May 2023 were included. The general condition and POMS of patients were collected. All patients were divided into 3 groups of low-TMD/ middle-TMD/ high-TMD(TMD≤90 scores; 90 scores105 scores). The χ2 test was used for categorical variables, and the continuous variables were tested for normal distribution. If they followed a normal distribution, the independent sample t test (for homogeneous variance) or the Welch′s t test (for unequal variance) was used for comparison between the two groups, and one-way analysis of variance was used for comparison between multiple groups; if they did not follow a normal distribution, the Kruskal-Wallis H test was used for comparison between groups. Patients with TMD>90 scores were defined as the negative emotion group. Gender, age, education level, economic income status, and TMD were included in the two-step cluster analysis (TCA) to obtain three cluster groups and analyze the differences between the groups. Logistic regression was used to analyze the risk factors. Results:The study found that patients with rheumatic diseases with low serum albumin levels ( F=6.26, P=0.003), low education level ( χ2=8.36, P=0.015), low economic level ( χ2=15.59, P<0.001), short disease course ( H=28.01, P<0.001), and high disease activity ( χ2=56.93, P<0.001) had higher TMD scores, which was not related to the type of disease ( χ2=4.81, P=0.090). The negative mood group had a higher proportion of females (57.6% vs. 73.4%, χ2=5.16, P=0.023), a shorter course of disease [24(12, 48) months vs. 48(24, 93) months, Z=13.58, P<0.001], and a lower serum albumin [(42.2±4.0) g/L vs. (44.0±3.4)g/L, t=-14.09, P=0.002], low level of education ( χ2=9.04, P=0.029), low level of income ( χ2=10.29, P=0.036), high disease activity ( χ2=61.91, P<0.001). The results of cluster analysis indicated that the above factors were significantly different among the three cluster groups except the course of disease. It is noteworthy that age ( F=19.25, P<0.001) and serum albumin ( F=5.64, P=0.004) had the lowest value and the highest TMD score ( F=5.64, P<0.001). Regression analysis showed that gender, disease course and disease activity were related factors to the occurrence of negative emotions, and high disease activity was a risk factor [ OR(95% CI) =26.58(4.53, 156.09), P<0.001]. Men [ OR(95% CI)=0.20 (0.08, 0.50), P=0.001) and the course of [ OR(95% CI)=0.99 (0.98, 1.00), P=0.007) as the protective factors. Conclusion:Male, serum albumin level, education level, income level, disease course and disease activity were the main factors affecting the mood state of patients with rheumatism, in which high disease activity was the risk factor, male and long disease course were the protective factors.

Objective To study the chemical composition of and identify its active components.Methods The chemical constituents of Dendrobium Primulinum were extracted using solvents,followed by separation through silica gel and gel column chromatography,with structural identification performed via spectral analysis.The in vitro activity screening of some compounds was conducted using the MTT assay.Results Seven compounds were isolated and identified from Dendrobium primulinum,namely 7-dihydroxy-2,4-methoxyphenanthrene(1),densiflorol B(2),3,4,7-trihydroxy-2-methoxy-9,10-dihydrophenanthrene(3),thunalbene(4),phillygenin(5),3 β-hydroxy-5 α,8 α-epidioxyergosta-6,22-diene(6)、4-hydroxy-3,5-dimethoxy--cinnamaldehyde(7).Antitumor activity tests were performed on compounds 1 to 5,revealing that compound 1 exhibited strong inhibitory activity against the MCF-7/S cell line,with an IC50 of 5.13 μM.Conclusion Compounds 1 to 6 are reported for the first time from Dendrobium primulinum,while compound 7 is reported for the first time from this genus.

Objective:To develop the Discharge Readiness Scale for Patients with Chronic Skin Wounds and evaluate its reliability and validity.Methods:The Discharge Readiness Scale for Patients with Chronic Skin Wounds was developed through literature review, semi-structured interviews, Delphi expert consultation, and a pre-survey. Convenience sampling was employed to select 320 patients with chronic skin wounds hospitalized at Chongming Hospital, Shanghai University of Medicine and Health Sciences and Qingdao Municipal Hospital from June 2023 to December 2024 for formal investigation, conducting scale reliability and validity analysis. The critical ratio method and correlation coefficient method were used for project analysis. Content validity of the scale was assessed using item-level content validity index and average scale-level content validity index, and construct validity was evaluated through exploratory factor analysis and confirmatory factor analysis. Reliability analysis employed Cronbach's α coefficient.Results:A total of 320 questionnaires were distributed, and 304 valid questionnaires were collected, with a valid response rate of 95.0%. The average scale-level content validity index was 0.91, and the item-level content validity index ranged from 0.80 to 1.00. Exploratory factor analysis revealed that the cumulative variance contribution rate of the five common factors was 67.483%. The overall Cronbach's α coefficient for the scale was 0.831. The final constructed scale comprised five dimensions of trajectory stage cognition, wound self-care skills, symptom management, psychosocial adaptation, and health information acquisition and resource utilization, with a total of 26 items.Conclusions:The Discharge Readiness Scale for Patients with Chronic Skin Wounds demonstrates good reliability and validity, providing clinical healthcare professionals with a standardized assessment tool.

Objective:To investigate the gender differences in the causal relationship between testosterone-related hormones and type 2 diabetes mellitus(T2DM), and to analyze the mediating role of blood lipids in this relationship.Methods:Using two-sample Mendelian randomization(TSMR) and two-step Mendelian randomization(MR) methods, we explored the causal associations between testosterone-related hormones, T2DM, and blood lipids in different genders. The potential mediating role of blood lipids between testosterone-related hormones and T2DM was quantitatively assessed using multivariate Mendelian Randomization(MVMR).Results:In males, each standard deviation( SD) increase in genetically predicted total testosterone(TT) was associated with lower odds of T2DM( OR=0.90, 95% CI 0.82-0.97, P=0.009) and higher high-density lipoprotein-cholesterol(HDL-C) level( β=0.08 SD, 95% CI 0.03-0.13, P=0.002). In women, each SD rise in genetically predicted bioavailable testosterone(Bio-T) was associated with higher odds of T2DM( OR=1.24, 95% CI 1.10-1.40, P<0.001), lower HDL-C level( β=-0.13 SD, 95% CI -0.21--0.05, P<0.001). Mediation analysis revealed that HDL-C played a mediating role(7.83%) between Bio-T and T2DM in women. However, HDL-C showed no mediating effect between SHBG and TT levels on T2DM, and low-density lipoprotein-cholesterol(LDL-C) showed no mediating effect between TT levels on T2DM in men. Conclusions:Lower levels of TT and SHBG in men, and high levels of Bio-T in women may increase the risk of T2DM. In women, regulating HDL-C levels may offer a potential strategy for the prevention and treatment of T2DM related to Bio-T disorders.

[Objective] To evaluate the clinical application value of intrauterine perfusion with platelet-rich plasma (PRP) combined with in vitro fertilization-frozen-thawed embryo transfer (IVF-FET) in patients with chronic endometritis (CE). [Methods] A randomized controlled trial (RCT) was conducted, enrolling 60 CE patients undergoing artificial cycle frozen embryo transfer at our hospital from January 2022 to January 2024. Participants were randomly divided into three groups: Group A (routine frozen embryo transfer, n=20), Group B (routine frozen embryo transfer + one PRP intrauterine perfusion, n=20), and Group C (routine frozen embryo transfer + two PRP intrauterine perfusions, n=20). Endometrial thickness during the transformation and transplantation phases, uterine artery pulsatility index (PI), resistance index (RI), systolic peak velocity/end-diastolic velocity (S/D) ratio during transplantation, serum levels of IL-2, IL-4, IL-6, IL-10, and TNF-α during transplantation, as well as biochemical pregnancy rate, clinical pregnancy rate, live birth rate, and early miscarriage rate were compared across groups. [Results] No significant differences in endometrial thickness were observed among the three groups during the transformation phase (P>0.05). During the transplantation phase, endometrial thickness in Groups C and B was significantly higher than in Group A[9.54 (8.96-10.22) and 8.90 (8.34-9.72) vs 8.37 (7.89-8.75) mm, P<0.05], with Group C showing greater thickness than Group B (Z=3.733, P<0.05). Endometrial thickness in Groups C and B during transplantation was significantly increased compared to their respective transformation phases (Z=2.191, 2.462; P<0.05). Groups C and B exhibited lower PI, RI, and S/D values than Group A[PI:1.87 (1.77-1.97), 1.94 (1.88-2.15) vs 2.43 (2.35-2.49); RI:0.75 (0.73-0.77), 0.78 (0.75-0.81) vs 0.84 (0.83-0.86); S/D:2.61 (2.33-3.42), 3.01 (2.20-3.93) vs 3.72 (3.06-4.49); P<0.05]. Group C demonstrated lower PI and RI than Group B (P<0.05). IL-2 levels in Groups C and B were higher than in Group A[3.88 (2.71-5.01), 3.59 (2.73-4.38) vs 3.16 (2.11-3.25) ng/L, P<0.05], while IL-4, IL-6, IL-10, and TNF-α levels were significantly lower (IL-4: Z=1.428, 2.421; IL-6: Z=1.754, 2.435; IL-10: Z=1.754, 2.854; TNF-α: Z=1.961, 1.765; P<0.05). Group C had lower IL-6 levels than Group B (Z=3.976, P<0.05). Biochemical pregnancy rate, clinical pregnancy rate, and live birth rate in Group C were significantly higher than in Group A (75% vs 40%, 70% vs 35%, 60% vs 20%, P<0.05). No significant differences in early miscarriage rates were observed among the groups (χ²=3.750, P>0.05). [Conclusion] Intrauterine autologous PRP perfusion in CE patients enhances pregnancy and live birth rates, improves pregnancy outcomes post-FET, and demonstrates superior efficacy in endometrial repair and receptivity with two PRP perfusions compared to a single perfusion. This provides a safe and effective therapeutic option for optimizing outcomes in CE patients with prior implantation failure.

Objective::To analyze fetal renal abnormality genetic features and the prenatal characteristics of the 17q12 microdeletion syndrome.Methods::This prospective cohort study examined prenatal ultrasound findings of renal abnormalities in pregnant women who underwent single nucleotide polymorphism (SNP) array or copy number variation sequencing (CNV-seq) testing on amniotic fluid or fetal tissue at Tianjin Central Obstetrics and Gynecology Hospital between January 2016 and August 2022. The study cohort comprised women with advanced maternal age, fetal ultrasound anomalies, high-risk non-invasive prenatal testing results, or suspected 17q12 microdeletion syndrome. Comprehensive clinical data, including maternal age, detailed ultrasound findings, and pregnancy outcomes, were systematically collected. SNP-array analysis was conducted using an Affymetrix CytoScan 750 K Array Chip to identify CNVs and loss of heterozygosity, while CNV-seq was performed on the Illumina HiSeq 2000 platform. Detected variants were classified according to the American College of Medical Genetics and Genomics guidelines. Statistical analyses were performed using SPSS version 27.0.Results::Abnormal renal development was identified in 141 patients, among whom 26 exhibited hyperechogenic kidneys (HCK). Of these, 12 cases were associated with 17q12 microdeletion syndrome, while the remaining 14 were linked to other chromosomal abnormalities. When excluding patients with HCK, those diagnosed with polycystic kidney disease demonstrated a higher prevalence of chromosomal abnormalities compared to those with multicystic dysplastic kidney and renal dysplasia. Although isolated conditions such as horseshoe kidney, hydronephrosis, ectopic kidney, and unilateral kidney typically presented with normal chromosomal findings, the incidence of chromosomal abnormalities increased when these conditions coexisted with other anomalies. A detailed analysis of the correlation between 17q12 microdeletion syndrome and HCK revealed that 12 out of the 14 patients diagnosed with 17q12 microdeletion syndrome exhibited HCK. Genetic testing confirmed the syndrome in seven patients, with five cases attributed to novel mutations and two cases resulting from inherited mutations.Conclusion::Fetal HCK was closely associated with the 17q12 microdeletion syndrome, and polycystic kidney disease showed a higher rate of chromosomal abnormalities. Chromosome test results were mostly normal in patients with other renal abnormalities, such as kidney dysplasia, horseshoe kidneys, hydronephrosis, kidney deficiency, and ectopic kidneys. Prenatal diagnosis is recommended, especially in cases of non-isolated fetal renal abnormalities. This study provides strong evidence supporting a link between fetal renal abnormalities and genetic syndromes.
