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.

OBJECTIVES:
To explore the therapeutic mechanism of Guizhi Fuling (GZFL) Pellets against cervical cancer.
METHODS:
Publicly available databases were used to identify the targets of GZFL Pellets and cervical cancer to construct the protein-protein interaction (PPI) network, followed by GO biological process and KEGG pathway enrichment analysis of the hub genes. The "Traditional Chinese Medicine-Active Ingredients-Targets-Pathways" network for GZFL Pellets in cervical cancer treatment was generated using Cytoscape v10.0.0, and molecular docking of the drug and potential targets was performed to predict the specific targets of active components in Guizhi Fuling Pellets. The inhibitory effects of hederagenin, an active ingredient in GZFL Pellets, was tested in cultured cervical cancer cells and in nude mice bearing cervical cancer xenografts.
RESULTS:
GZFL Pellets contain 338 active components targeting 247 action sites. A total of 10127 cervical cancer-related targets were obtained, and among them 195 were identified as potential therapeutic targets of GZFL Pellets for cervical cancer treatment, including the key targets of GABRA1, PTK2, JAK2, HTR3A, GSR, and IL-17. Molecular docking study showed low binding energies of the active components such as hederagenin, campesterol, and stigmasterol for protein-molecule interaction. GO enrichment analysis suggested that GZFL Pellets inhibited cervical cancer primarily by regulating responses to steroid hormones, oxidative stress, and lipopolysaccharides. Among the active components of GZFL Pellets, hederagenin was found to inhibit cervical cancer cells in vitro and significantly reduced STAT3 phosphorylation level in the cancer cells. In nude mice bearing cervical cancer xenografts, hederagenin effectively inhibited tumor growth rate without causing obvious adverse effects.
CONCLUSIONS
GZFL Pellets inhibit cervical cancer cell growth through its multiple active components that target different pathways. Among these components, hederagenin inhibits tumor cell growth possibly by directly binding to JAK2 protein to inhibit STAT3 phosphorylation.

Objective:To analyze the related factors of membranous urethral length in patients with benign prostatic hyperplasia (BPH) and the early recovery of urinary control function after Holmium laser enucleation of the prostate (HoLEP).Methods:A retrospective study was conducted to analyze the case data of 124 patients with BPH admitted to the Yan′an University Affiliated Hospital from January 2017 to January 2023. According to the recovery of postoperative urinary control function, the patients were divided into the urinary control group ( n=81) and the urinary incontinence group ( n=43). The clinical data of the two groups of patients were collected, including age, body mass index, comorbidities, etc. The perioperative indicators [including prostate volume, prostatic specific antigen, membranous urethral length, international prostate symptom score (IPSS), maximum bladder capacity, degree of prostate protrusion into the bladder, etc.], the urodynamic indicators before the operation and 6 months after the operation (including maximum urine flow rate, maximum urethral pressure and bladder compliance) and the urinary control situation of the two groups of patients were observed. Measurement data were expressed as mean±standard deviation ( ± s), and the independent sample t-test was used for comparison between groups; count data were expressed as the cases and percentage, and Chi-square test was used for comparison between groups. Univariate and multivariate Logistic regression analysis were used to evaluate the influencing factors of early urinary control function recovery after HoLEP. Results:All patients successfully completed the surgery, and the follow-up was conducted 6 months after the operation as the time point. The results of univariate analysis showed that there were no statistically significant differences in age, body mass index, comorbidities, prostatic specific antigen, IPSS score and the degree of prostate protrusion into the bladder between the urinary control group and the urinary incontinence group ( P>0.05). The operation time, indwelling catheter time, prostate volume, preoperative membranous urethral length, postoperative membranous urethral length and the postoperative maximum bladder capacity of the two groups of patients all showed statistically significant differences ( P<0.05). Before the operation, there were no statistically significant differences in urodynamic indicators such as maximum urinary flow rate, maximum urethral pressure and bladder compliance between the two groups of patients ( P>0.05). Six months after the operation, the maximum urinary flow rate, the maximum urethral pressure and the bladder compliance in the two groups of patients increased compared with those before the operation. Moreover, the maximum urinary flow rate [(10.48±0.65) mL/s vs (9.41±0.53) mL/s], the maximum urethral pressure [(41.25±3.46) cmH 2O vs (38.21±3.16) cmH 2O], and bladder compliance [(32.23±3.13) cmH 2O vs (30.23±2.35) cmH 2O] were higher than those in the urinary incontinence group, and the differences were statistically significant ( P<0.05). The results of multivariate Logistic regression analysis showed that operation time ≥1 h, indwelling catheter time ≥5 d, prostate volume ≥60 mL, preoperative membranous urethral length <14 mm, and postoperative membranous urethral length <13 mm were independent risk factors for the recovery of early urinary control function after HoLEP ( OR>1, P<0.05), the maximum bladder capacity after surgery was an independent protective factor for the recovery of early postoperative urinary control function ( OR<1, P<0.05). Conclusions:Preoperative membranous urethral length <14 mm and postoperative membranous urethral length <13 mm are risk factors affecting the recovery of early urinary control function after HoLEP in patients with BPH. A longer membranous urethral length can reduce the risk of postoperative complications and accelerate the recovery of urinary control function in patients.

ObjectiveTo investigate the effect of Tangbikang granules on oxidative stress of sciatic nerve in diabetic rats by regulating adenylate activated protein kinase/peroxisome proliferator-activated receptor γ coactivator-1α/mitochondrial Sirtuins 3 (AMPK/PGC-1α/SIRT3) signaling pathway. MethodThe spontaneous obesity type 2 diabetes model was established using ZDF rats. After modeling, they were randomly divided into high, medium, and low dose Tangbikang granule groups (2.5, 1.25, 0.625 g·kg-1·d-1) and lipoic acid group (0.026 8 g·kg-1·d-1), and the normal group was set up. The rats were administered continuously for 12 weeks after modeling. The blood glucose of rats was detected before intervention and at 4, 8, 12 weeks after intervention. At the 12th week, motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV), nerve blood flow velocity, mechanical pain threshold, and thermal pain threshold were detected. The sciatic nerve was taken for hematoxylin-eosin (HE) staining to observe the tissue morphology. The ultrastructure of the sciatic nerve was observed by transmission electron microscope. The expression levels of superoxide dismutase (SOD), malondialdehyde (MDA), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in sciatic nerve were determined by enzyme-related immunosorbent assay (ELISA). The mRNA expressions of AMPKα, AMPKβ, PGC-1α, and SIRT3 in sciatic nerve were determined by real-time polymerase chain reaction (Real-time PCR). ResultCompared with the normal group, fasting blood glucose in the model group was increased at each time point (P<0.01). The mechanical pain threshold was decreased (P<0.05), and the incubation time of the hot plate was extended (P<0.01). MNCV, SNCV, and nerve blood flow velocity decreased (P<0.05). The expression level of SOD was decreased (P<0.01). The expression levels of MDA, IL-1β, and TNF-α were increased (P<0.01). The mRNA expression levels of AMPKα, AMPKβ, PGC-1α, and SIRT3 were decreased (P<0.01). The structure of sciatic nerve fibers in the model group was loose, and the arrangement was disordered. The demyelination change was obvious. Compared with the model group, the fasting blood glucose of rats in the high dose Tangbikang granule group was decreased after the intervention of eight weeks and 12 weeks (P<0.01). The mechanical pain threshold increased (P<0.05). The incubation time of the hot plate was shortened (P<0.01). MNCV, SNCV, and Flux increased (P<0.05). The expression level of SOD was increased (P<0.01). The expression levels of MDA, IL-1β, and TNF-α were decreased (P<0.01). The mRNA expression levels of AMPKα, AMPKβ, PGC-1α, and SIRT3 were increased (P<0.01). The sciatic nerve fibers in the high-dose Tangbikang granule group were tighter and more neatly arranged, with only a few demyelinating changes. The high, medium, and low dose Tangbikang granule groups showed a significant dose-effect trend. ConclusionTangbikang granules may improve sciatic nerve function in diabetic rats by regulating AMPK/PGC-1α/SIRT3 signaling pathway partly to inhibit oxidative stress.

Objective:To investigate the effect of 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip in small volume benign prostatic hyperplasia (BPH).Methods:The case data of 120 patients diagnosed with small volume BPH in the Yan′an University Affiliated Hospital from June 2020 to June 2022 were retrospectively analyzed, and they were divided into improved group and conventional group according to different treatment methods, with 60 cases in each group. Patients in the improved group were treated with 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip, and patients in the conventional group were treated with 980 nm semiconductor laser vaporization of prostate. The sexual function of the patients was evaluated by the international erectile function index-5(IIEF-5) score, erectile hardness score (EHS) and retrograde ejaculation before surgery and 1, 3, 6, and 12 months after surgery. International prostate symptom scale (IPSS), quality of life (QOL) score, the maximum urine flow rate (Qmax) and postvoid residual urine (PVR) were used to evaluate urinary control function. The incidence of urinary incontinence, bladder neck contracture and other complications were compared between the two groups. Measurement data were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups. The count data were expressed as cases and percentage, and Chi-square test was used for comparison between groups. Results:There was no significant difference in PVR, Qmax, IPSS score, QOL score, IIEF-5 score and EHS score between two groups ( P>0.05). In terms of PVR, Qmax, IPSS score, QOL score, IIEF-5 score and EHS score at 1, 3, 6 and 12 months after surgery, all these parameters were significantly improved compared with the preoperative, the differences were statistically significant ( P< 0.05). However, there was no significant difference between the two groups ( P> 0.05). There was no significant difference in IIEF-5 score and EHS score between the two groups during postoperative follow-up and before and after operation ( P> 0.05). The incidence of retrograde ejaculation rate in the improved group was lower than that in the conventional group during the follow-up 1, 3, 6 months after surgery, and the difference was statistically significant ( P<0.05). In the follow-up 1, 3 months after surgery, the incidence of stress urinary incontinence in the improved group was lower than that in the conventional group, the differences were statistically significant ( P< 0.05). At follow-up 6, 12 months after surgery, the rates of stress urinary incontinence were similar between the two groups, and the difference was not statistically significant ( P> 0.05). In the follow-up 12 months after surgery, there were 2 cases (3.33%) of bladder and neck contracture in the improved group, and 8 cases (13.33%) in the conventional group, the difference was statistically significant ( P<0.05). Conclusions:The effect of 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip in small volume BPH patients is similar to that of conventional vaporization, and the operation time is short. At the same time, the proximal 1 cm tissue of the verticulae and the integrity of the bladder neck are preserved, and the internal and external sphincter of the urethra are protected, thus improving the immediate postoperative urinary control rate and the incidence of retrograde ejaculation in small volume BPH patients.

Objective:To observe the effects of Qifu Lizhong Enema Prescription on ulcerative colitis rats with yang deficiency of spleen and kidney syndrome; To discuss its mechanism.Methods:Totally 70 male SD rats were randomly divided into blank group, model group, mesalazine group, Qifu Lizhong Guanchang Prescription high-, medium- and low-dosage groups; blank group ( n=10), other groups ( n=12). Except for the blank group, the other groups used bitter cold purgative therapy (Dahuang Decoction) by gavage, and combined with trinitrobenzen sulfonic acid (TNBS) +55% ethanol compound method to induce UC rat model. After successful modeling, the blank group and model group were given 1 ml normal saline enema daily, Qifu Lizhong Enema Prescription groups were given Qifu Lizhong Enema Prescription 3.00, 1.50, 0.75 g/kg enema daily, and the mesalazine group was given mesalazine 0.03 g/kg enema daily, once a day for consecutive 14 days. After 14 days, Disease Activity Index (DAI) score was performed, and hematoxylin-eosin staining (HE) was used to observe the pathological tissues of the colon. The expressions of Occludin and adhesion molecules A (JAM-A) protein in colon tissue were detected by immunohistochemistry and Western blot. Results:HE results showed that the mucosal structure was damaged, inflammatory cells were infiltrated, edema and ulcer foci were observed in model group. The mucosal structure of mesalazine group and Qifu Lizhong Enema Prescription groups were intact, and inflammatory infiltration, edema and ulcer of neoepithelial were improved. Compared with model group, the DAI scores of Qifu Lizhong Enema Prescription groups decreased ( P<0.01), the expressions of Occludin and JAM-A in Qifu Lizhong Guanchang Prescription high- and medium-dosage groups significantly increased ( P<0.05). Conclusion:Qifu Lizhong Enema Prescription can significantly relieve the symptoms and pathological morphology of UC rats, and the mechanism of repairing intestinal mucosal barrier may be related to up-regulating the expressions of Occludin and JAM-A proteins.
