Objective:To evaluate the efficacy of drug-coated balloons (DCB) in hemodialysis patients with peripheral artery disease (PAD) involving infrapopliteal lesions.Methods:A retrospective analysis was conducted on 53 hemodialysis patients (56 limbs, 66 lesions) with infrapopliteal PAD who underwent DCB treatment between Dec 2018 and Dec 2021. The primary outcome was improvement in Rutherford classification, while secondary outcomes included target lesion revascularization (TLR) and wound healing rate. Safety endpoints were all-cause mortality, amputation-free survival, and amputation rate.Results:The mean lesion length was (145.2±78.4) mm, and 87.5% of patients were of Rutherford grade ≥4. The median follow-up period was 14 months. Rutherford classification significantly improved at 3 and 12 months ( P< 0.001). At 12 months, TLR was 16.6%, wound healing rate was 68.6%, amputation-free survival was 73.2%, all-cause mortality was 19.8%, and amputation rate was 8.9%. Multivariate Cox regression indicated that high WIfI risk ( HR=3.936, 95% CI: 1.079-14.355, P=0.038) was an independent predictor of amputation-free survival. Conclusion:DCB is effective and safe for hemodialysis patients with infrapopliteal artery disease, while high WIfI risk predicts poor prognosis.

The intersection target PPI network was constructed through STRING 11.5 database, and Cytoscape 3.9.1 software was used for network topology analysis; Metascape database was used for GO function and KEGG pathway enrichment analysis of core targets; Cytoscape 3.9.1 was used to construct Zhenqi Fuzheng Capsules component-target-pathway network; Autodock Tools software was used to carry out molecular docking of core targets and active components.Results:Totally 31 active components and 180 targets of Zhenqi Fuzheng Capsules were screened out. TNF, IL6, AKT1, IL1B, TP53, VEGFA, RELA, EGFR and CASP3 were identified as the core targets. GO functional enrichment analysis obtained 1 436 biological processes, 53 cellular components, and 117 molecular functions. KEGG pathway enrichment analysis obtained 167 pathways, which were related to pathways in cancer, AGE-RAGE signaling pathway in diabetic complications, and IL-17 signaling pathway was closely related. Molecular docking results showed that core targets such as AKT1 and TNF had good binding activity to quercetin, kaempferol, and luteolin.Conclusion:The main active components of Zhenqi Fuzheng Capsules in the adjuvant treatment of AIDS are quercetin, kaempferol and luteolin, which may treat AIDS through the IL-17 signaling pathway.

Pro-inflammatory cytokines selectively induce specific signals to regulate host responses. Since the immunological imbalance caused by abnormal release of cytokines is involved in the development of many diseases, cytokine-specific detections are of great clinical significance for disease diagnosis and efficacy monitoring. Aptamers are single-stranded nucleic acid sequences which can bind to the target with high selectivity and affinity. It has attracted much attention in the development of novel aptamers-based methods for the detection of specific biomarkers of inflammatory diseases. This paper reviewed recent advances in electrochemical and optical aptasensors for the detection of tumor necrosis factor-α, interleukin-6, transforming growth factor-β, interferon-γ and interleukin-8. The findings offered valuable insights into the clinical application potential and challenges of nucleic acid aptamers in the detection of key inflammatory cytokines, providing a meaningful reference for the development of aptamer-based cytokines sensitive detection point-of-care testing equipment and novel diagnostic strategies for inflammatory disorders.

Objective:To investigate the effect of treatment with orchiopexy at different ages on the clinical outcomes of nonobstructive azoospermia (NOA) patients with a history of cryptorchidism who underwent microdissection testicular sperm extraction (microTESE) combined with intracytoplasmic sperm injection (ICSI).Methods:NOA patients undergoing microTESE combined with ICSI from December 2013 to August 2019 in the ICSI treatment cycle in Assisted Reproduction Center of Northwest Women and Children's Hospital were collected in this retrospective cohort study. According to the history of cryptorchidism, the patients were divided into cryptorchidism group and non-cryptorchidism group. The sperm retrieval rates (SRRs) were assessed between these two groups. Then, based on the timing of treatment with orchiopexy, the NOA patients with orchidopexy were subdivided into prepubertal group and pubertal-postpubertal group. The SRRs and the pregnancy outcomes were also assessed.Results:There were 34 NOA patients with cryptorchidism and 604 NOA patients without cryptorchidism underwent microTESE. The SRRs in NOA patients with or without cryptorchidism were 85.3% (29/34) and 40.2% (243/604), respectively. The differences were statistically significant ( P<0.001). In the prepubertal surgery group, sperm was detected in 17 cases, while in the pubertal-postpubertal surgery group, the sperm was detected in 12 cases. The differences were statistically significant ( P=0.044). The total clinical pregnancy rate of cryptorchidism NOA patients treated with ICSI was 65.4% (17/26). Among these individuals, the clinical pregnancy rate of the prepubertal group was 62.5% (10/16) and the pubertal-postpubertal group was 70.0% (7/10). There were no statistical differences in clinical pregnancy rate. Some other clinical pregnancy outcomes, including miscarriage rate in early pregnancy, the rate of cycle with 2PN and the rate of cycle with top-quality embryo, also showed no differences between the two groups. In pathology analysis, all the cryptorchidism NOA patients with failure sperm retrieval were Sertoli cell only syndrome (SCOS). The pubertal-postpubertal group had a significant higher morbidity of SCOS [76.5% (13/17)] compared with the prepubertal group [35.3% (6/17)] ( P=0.016). In addition, the volume of testis, the level of follicle-stimulating hormone and testosterone were not statistically associated with SRR. Conclusion:The SRR of NOA patients with cryptorchidism was higher than those without cryptorchidism. The age at orchidopexy operation may have little effect on the pregnancy outcome of ICSI. It may be more beneficial for microTESE to obtain sperm by undergoing orchiopexy as early as possible.

PURPOSE: Kallikrein (KLK) proteases are hormone-like signaling molecules with critical functions in different cancers. This study investigated the expression of KLK6 in gastric cancer and its potential role in the growth, migration, and invasion of gastric cancer cells. MATERIALS AND METHODS: In this study, we compared protein levels of KLK6, vascular endothelial growth factor (VEGF), and matrix metallopeptidase (MMP) 9 in normal gastric epithelial and gastric cancer cell lines by western blot. Fluorescence-activated cell sorting was employed to sort 2 clones of SGC-7901 cells with distinct KLK6 expression, namely, KLK6-high (KLK6high) and KLK6-low (KLK6low), which were then expanded. Lastly, immunohistochemical analysis was performed to investigate KLK6 expression in gastric cancer patients. RESULTS: The expression levels of KLK6, VEGF, and MMP 9, were significantly higher in the gastric cancer cell lines SGC-7901, BGC-823, MKN-28, and MGC-803 than in the normal gastric epithelial cell line GES-1. Compared to KLK6low cells, KLK6high cells showed enhanced viability, colony-forming ability, migration, and invasion potential in vitro. Importantly, immunohistochemical analysis of a human gastric cancer tissue cohort revealed that the staining for KLK6, VEGF, and MMP9 was markedly stronger in the cancerous tissues than in the adjacent normal tissues. KLK6 expression also correlated with that of VEGF and MMP9 expression, as well as several key clinicopathological parameters. CONCLUSIONS: Together, these results suggest an important role for KLK6 in human gastric cancer progression.

Gardner syndrome is a rare disease in oral and maxillofacial diseases which is characterized by intestinal polyposis, multiple osteomas, skin and soft tissue tumors. Early treatment has a better prognosis; therefore the early diagnosis of Gardner syndrome is very important. Maxillofacial pathology always appears to precede the other pathologies, so the importance of early detection of the syndrome by dentists is also emphasized. This review summarizes the etiology of Gardner syndrome-related mutations and the clinical manifestations of Gardner syndrome characterized by oral and maxillofacial deformities, multiple gastrointestinal polyps, and desmoid tumour, and their associated treatment.

AIM: To investigate how brain-dead state affects the heart structure and function and the effect of PKC-? in BA-Ma mini pigs.METHODS: Ten Ba-Ma mini pigs were randomized into 2 groups: brain-dead group(n=5),and control group(n=5).The brain-dead model was made by increasing intracranial pressure,while the control group was maintained anesthesia for 24 h.The concentrations of cTnT,TNF-?,IL-1? and IL-6 in serum were determined at 6,12 and 24 h after brain death.At 24 h,heart tissues were observed by HE staining and electron microscope.The expression of PKC-? was detected by immunohistochemistry and RT-PCR.RESULTS:(1) Histological changes of myocardium: flaky bleeding under endocardium and dissolution of myocardium were found in optical microscope.In electron microscope dropsical mitochondria and confluent muscle fiber were found.(2) Changes of serum cTnT: serum cTnT for brain-dead group began to increase gradually since 6 h,and were significantly higher at each time point than those in control group(P
