Abstract	Klinefelter syndrome (KS) is the most common genetic cause of human male infertility. However, the effect of the extra X chromosome on different testicular cell types remains poorly understood. Here, we profiled testicular single-cell transcriptomes from three KS patients and normal karyotype control individuals. Among the different somatic cells, Sertoli cells showed the greatest transcriptome changes in KS patients. Further analysis showed that X-inactive-specific transcript ( XIST ), a key factor that inactivates one X chromosome in female mammals, was widely expressed in each testicular somatic cell type but not in Sertoli cells. The loss of XIST in Sertoli cells leads to an increased level of X chromosome genes, and further disrupts their transcription pattern and cellular function. This phenomenon was not detected in other somatic cells such as Leydig cells and vascular endothelial cells. These results proposed a new mechanism to explain why testicular atrophy in KS patients is heterogeneous with loss of seminiferous tubules but interstitial hyperplasia. Our study provides a theoretical basis for subsequent research and related treatment of KS by identifying Sertoli cell-specific X chromosome inactivation failure.

Abstract	Background: The development of single-cell sequencing technology has expanded the understanding of cell heterogeneity and disease progression in the male genitourinary system. However, complex processing and unprofessional analytical annotations limit the daily use and widely sharing of published datasets. Objectives: Single-cell sequencing data of male-specific tissues and organs. Materials and methods: The data were downloaded from published studies and were processed based on the Seurat R package, including quality control, cell clustering, reduction and graph generation, and cell type annotation were differentiated by referring to the related paper or recognized cell markers. Input and visual results output through the Shiny package, which was loaded into the remote server. Results: The current version of the Male Health Atlas database includes two species (human and mouse), five male-specific tissues and organs (testis, epididymis, vas deferens, corpus cavernosum, and prostate), and eight major cell types, with a total of 57 samples and 258,428 single-cell profiles. The results were divided into two main parts: Cell Clustering and Gene Display. In Cell Clustering section, visitors are free to change cell dimensionality reduction (t-distributed stochastic neighbor embedding, or uniform manifold approximation and projection), color palette, and annotation (cell type or sample type). The Gene Display section includes a reduced dimension scatter plot, violin plot, and bubble plot. Visitors can easily view the expression characteristics of single or multiple genes, and compare the expression differences between different cell types or groups. Discussion and conclusion: Male Health Atlas is the first single-cell database website in the field of andrology and male reproduction, providing researchers with single-cell sequencing resources and an accessible tool. Male Health Atlas is freely available at http://malehealthatlas.cn/.

Abstract	MiR-664b-3p has been reported to play a crucial role in cancer progression. This research explores the biological effect and molecular mechanisms of miR-664b-3p in cell proliferation, apoptosis, migration, and invasion of colon cancer. The expression level of miR-664b-3p and Budding uninhibited by benzimidazole 3 (Bub3) in colon cancer cell lines and tissues were detected and analyzed using quantitative real-time PCR and bioinformatics method. The Western blot measured the expression level of proliferation-related, migration-related, and apoptosis-related proteins. CCK-8 assessed cell viability, and the cell proliferation, migration, and invasion were detected by the Edu assay, wound-healing assay, and transwell assay, respectively. Annexin/propidium iodide (PI) assays detected apoptosis of cells. The target of miR-664b-3p was predicted by bioinformatics methods and then validated by gene engineering technology. MiR-664b-3p was downregulated in colon cancer tissues and cells. The cell proliferation, migration, and invasion of cells were inhibited after transfecting by miR-664b-3p mimics, whereas apoptosis was promoted. Over-expression of miR-664b-3p could reduce the expression of proliferation-promoted proliferating cell nuclear antigen (PCNA), proliferation marker protein Ki-67 (Ki-67), migration-promoted Cyclooxygenase-2 (COX-2), Matrix Metallopeptidase 2 (MMP-2), and Matrix Metallopeptidase 9 (MMP-9), and apoptosis-inhibited protein (Bcl-2) while increasing the expression of apoptosis-promoted BCL2-Associated X Protein (Bax), caspase-3, and caspase-9 proteins. The study indicated that miR-664b-3p plays a significant role in colon cancer and could regulate the progression of colon cancer tumor growth by suppressing the expression of BUB3 protein. These findings provide a novel strategy to screen and treat colon cancer.

Abstract	Ex vivo tissue culture of the human corpus cavernosum (CC) can be used to explore the tissue structural changes and complex signaling networks. At present, artificial CC-like tissues based on acellular or three-dimensional (3D)-printed scaffolds are used to solve the scarcity of primary penis tissue samples. However, inconvenience and high costs limit the wide application of such methods. Here, we describe a simple, fast, and economical method of constructing artificial CC-like tissue. Human CC fibroblasts (FBs), endothelial cells (ECs), and smooth muscle cells (SMCs) were expanded in vitro and mixed with Matrigel in specific proportions. A large number of bubbles were formed in the mixture by vortexing combined with pipette blowing, creating a porous, spongy, and spatial structure. The CC FBs produced a variety of signaling factors, showed multidirectional differentiation potential, and grew in a 3D grid in Matrigel, which is necessary for CC-like tissue to maintain a porous structure as a cell scaffold. Within the CC-like tissue, ECs covered the surface of the lumen, and SMCs were located inside the trabeculae, similar to the structure of the primary CC. Various cell components remained stable for 3 days in vitro, but the EC content decreased on the 7th day. Wingless/integrated (WNT) signaling activation led to lumen atrophy and increased tissue fibrosis in CC-like tissue, inducing the same changes in characteristics as in the primary CC. This study describes a preparation method for human artificial CC-like tissue that may provide an improved experimental platform for exploring the function and structure of the CC and conducting drug screening for erectile dysfunction therapy.

Abstract	Abstract: The regulation of spermatogonial proliferation and apoptosis is of great significance for maintaining spermatogenesis. The single-cell RNA sequencing (scRNA-seq) analysis of the testis was performed to identify genes upregulated in spermatogonia. Using scRNA-seq analysis, we identified the spermatogonia upregulated gene origin recognition complex subunit 6 (Orc6), which is involved in DNA replication and cell cycle regulation; its protein expression in the human and mouse testis was detected by western blot and immunofluorescence. To explore the potential function of Orc6 in spermatogonia, the C18-4 cell line was transfected with control or Orc6 siRNA. Subsequently, 5-ethynyl-2-deoxyuridine (EdU) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays, flow cytometry, and western blot were used to evaluate its effects on proliferation and apoptosis. It was revealed that ORC6 could promote proliferation and inhibit apoptosis of C18-4 cells. Bulk RNA sequencing and bioinformatics analysis indicated that Orc6 was involved in the activation of wingless/integrated (Wnt)/ β-catenin signaling. Western blot revealed that the expression of β-catenin protein and its phosphorylation (Ser675) were significantly decreased when silencing the expression of ORC6. Our findings indicated that Orc6 was upregulated in spermatogonia, whereby it regulated proliferation and apoptosis by activating Wnt/β-catenin signaling.

Abstract	Background: Hypoxia is associated with a poorer clinical outcome and resistance to chemotherapy in solid tumors; identifying hypoxic-related colorectal cancer (CRC) and revealing its mechanism are important. The aim of this study was to assess hypoxia signature for predicting prognosis and analyze relevant mechanism.Methods: Patients without chemotherapy were selected for the identification of hypoxia-related genes (HRGs). A total of six independent datasets that included 1,877 CRC patients were divided into a training cohort and two validation cohorts. Functional annotation and analysis were performed to reveal relevant mechanism.Results: A 12-gene signature was derived, which was prognostic for stage II/III CRC patients in two validation cohorts [TCGA, n = 509, hazard ratio (HR) = 2.14, 95% confidence interval (CI) = 1.18 – 3.89, P = 0.01; metavalidation, n = 590, HR = 2.46, 95% CI = 1.59 – 3.81, P < 0.001]. High hypoxic risk was correlated with worse prognosis in CRC patients without adjuvant chemotherapy (HR = 5.1, 95% CI = 2.51 – 10.35, P < 0.001). After integration with clinical characteristics, hypoxia-related gene signature (HRGS) remained as an independent prognostic factor in multivariate analysis. Furthermore, enrichment analysis found that antitumor immune response was suppressed in the high hypoxic group.Conclusions: HRGS is a promising system for estimating disease-free survival of stage II/III CRC patients. Hypoxia tumor microenvironment may be via inhibiting immune response to promote chemoresistance in stage II/III CRC patients.

Abstract	Numerous genes have been associated with multiple morphological abnormalities of the sperm flagella (MMAF), which cause severe asthenozoospermia and lead to male infertility, while the causes of approximately 50% of MMAF cases remain unclear. To reveal the genetic causes of MMAF in an infertile patient, whole-exome sequencing was performed to screen for pathogenic genes, and electron microscope was used to reveal the sperm flagellar ultrastructure. A novel heterozygous missense mutation in the outer dense fiber protein 2 (ODF2) gene was detected, which was inherited from the patient's mother and predicted to be potentially damaging. Transmission electron microscopy revealed that the outer dense fibers were defective in the patient's sperm tail, which was similar to that of the reported heterozygous Odf2 mutation mouse. Immunostaining of ODF2 showed severe ODF2 expression defects in the patient's sperm. Therefore, it was concluded that the heterozygous mutation in ODF2 caused MMAF in this case. To evaluate the possibility of assisted reproductive technology (ART) treatment for this patient, intracytoplasmic sperm injection (ICSI) was performed, with the help of a hypo-osmotic swelling test and laser-assisted immotile sperm selection (LAISS) for available sperm screening, and artificial oocyte activation with ionomycin was applied to improve the fertilization rate. Four ICSI cycles were performed, and live birth was achieved in the LAISS-applied cycle, suggesting that LAISS would be valuable in ART treatment for MMAF.

Abstract	In China, there are three basic clinical decision-making modes for patients, namely patients' autonomous decision-making mode, family decision-making mode and patient and family codetermination. They were produced under the unique background of Chinese medicine, Confucian philosophy and law in China. In this paper, the concepts, advantages and disadvantages of these three decision-making modes were analyzed. In addition, some suggestions were put forward for the improvement. The first is that we suggest to establish standards for choosing decision-making modes; the second is to further learn and publicize relevant laws; thirdly, the legal system needs to be further refined; and the last one is to carry out ethical ward round.

Abstract	Objective: To investigate the effect of Qilin Pills (QP) in facilitating the recovery of spermatogenic function in azoospermia (AS) mice and to explore its mechanism of regulating testicular spermatogenesis. Methods: Fifteen 4-week-old male mice were equally randomized into an AS model control, a low-dose QP and a high-dose QP group. The AS model was established in the mice by intraperitoneal injection of busulfan at 35 mg/kg. After modeling, the animals in the low- and high-dose QP groups were treated with Qilin Pills intragastrically at 2 000 and 8 000 mg/kg/d respectively while those in the model control group fed on a normal diet, all for 28 days. Then, all the mice were sacrificed for examination of the ultrastructures of the epididymis and testis by HE staining, detection of the specific markers of spermatogenic, Sertoli and Leydig cells by Western blot, and determination of the expressions of these markers in the testis tissue by immunofluorescence assay. Results: The number of spermatogenic cells in the testis tissue was significantly decreased in the AS model controls, with no spermatozoa in most of the seminiferous tubules in the epididymis (Johnsen's score: 5.2 ± 0.5). In the high-dose QP group, spermatogenic cells were tightly arranged with distinct layers in the seminiferous tubules, with a large number of spermatozoa but no non-sperm cells in the lumens of the epididymis (Johnsen's score: 9.4 ± 0.6). The number of spermatogenic cells in the testis was increased in the low-dose QP group with some spermatozoa in the seminiferous tubules as compared with that in the model control, but lower than in the high-dose group (Johnsen's score: 7.6 ± 0.6). The Johnsen's score was significantly lower in the model control than in the high- and low-dose QP groups (P < 0.01), and higher in the high-dose than in the low-dose QP group (P < 0.05). The expressions of the specific markers of Sertoli cells SCF, BMP4, SYCP3, DMC1 and Ki67 were also remarkably lower in the model control than in the high- and low-dose QP groups (P < 0.01), and higher in the high-dose than in the low-dose QP group (P < 0.05 or P < 0.01). No statistically significant differences were observed among the three groups of mice in the markers of spermatogonial stem cells (SSC) and undifferentiated SSCs UCHL1, STRA8, NGN3 and PLZF3 (P > 0.05). The expressions of the spermatocyte markers DMC1 and SYCP3 were markedly lower in the model control than in the high- and low-dose QP groups (P < 0.05 or P < 0.01), and higher in the high-dose than in the low-dose QP group (P < 0.05 or P < 0.01). The Ki67 fluorescence signals were distributed in the spermatogonia, with a higher intensity in the model control than in the high- and low-dose QP groups. The acrosome marker PNA was found mainly in the seminiferous tubules, with abundant fluorescence signals in the high- and low-dose QP groups but no obvious dot signals in the model controls. Conclusions: Qilin Pills may contribute to the meiosis of spermatogonia and promote spermatogenesis by improving the function of Sertoli cells in the testis.

Abstract	Non-obstructive azoospermia (NOA), which is defined as the absence of spermatozoa in the ejaculate secondary to impaired spermatogenesis within the testis, may be caused by a variety of etiologies, including varicocele-induced testicular damage, cryptorchidism, prior testicular torsion, post-pubertal mumps orchitis, gonadotoxic effects from medications, genetic abnormalities, chemotherapy/radiation, and other unknown causes currently classified as idiopathic (Cocuzza et al., 2013). The microdissection testicular sperm extraction (micro-TESE) technique involves a meticulous microsurgical exploration of the testicular parenchyma to identify and selectively extract larger seminiferous tubules that carry a higher probability of complete spermatogenesis (Schlegel, 1999). The Cornell group evaluated the efficacy of micro-TESE in 152 NOA patients with an associated history of cryptorchidism. In their series, spermatozoa were successfully retrieved in 116/181 attempts (64%), and the resulting pregnancy rate was 50% with a delivery rate of 38% (Dabaja and Schlegel, 2013). Franco et al. (2016) described a stepwise micro-TESE approach in NOA patients, which was considered to reduce the cost, time, and effort associated with the surgery. Alrabeeah et al. (2016) further reported that a mini-incision micro-TESE, carried through a 1-cm equatorial testicular incision, can be useful for micro-TESE candidates, particularly in patients with cryptozoospermia. We conducted a retrospective study of 20 consecutive NOA patients with a history of orchidopexy from May 2015 to March 2017.
