ObjectiveTo screen out the transcriptomes related to the intervention of Wuzi Yanzongwan on the spermatogenic function of semi-castrated male mice, and to explore its potential mechanism in the intervention of the progress of low spermatogenic function. MethodBalb/c mice were randomly divided into sham-operated group, model group, testosterone propionate group(0.2 mg·kg-1·d-1, intramuscular injection) and Wuzi Yanzongwan group(1.56 g·kg-1·d-1, intragastric administration) according to body weight, with 12 mice in each group. The right testicle and epididymis were extracted from the model group and the drug administration group to construct the semi-castrated model of low spermatogenic function, while the fur and the right scrotum of the sham-operated group were only cut and immediately sterilized and sutured. At the end of the intervention, hematoxylin-eosin(HE) staining was used to observe the histopathology of testis, enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of serum testosterone(T), luteinizing hormone(LH) and follicle stimulating hormone(FSH). The sperm count and motility of epididymis were measured by automatic sperm detector of small animal. Transcriptomic microarray technology was used to detect the mRNA expression level of testicular tissue in each group, the transcriptome of genes related to the regulation of Wuzi Yanzongwan was screened, and three mRNAs were selected for Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) to verify the transcriptome data. Through the annotation analysis of Gene Ontology(GO) and the signaling pathway analysis of Kyoto Encyclopedia of Genes and Genomes(KEGG), the related functions of drugs regulating transcriptome were analyzed. ResultCompared with the sham-operated group, the testicular tissue of mice in the model group showed spermatogenic injury, contraction and vacuolization of the seminiferous tubules, reduction of spermatogenic cells at all levels, widening of the interstitial space, obstruction of spermatogonial cell development and other morphological abnormalities, and serum T significantly decreased, LH significantly increased(P<0.01), and FSH elevated but no statistically significant difference, the count and vitality of epididymal sperm significantly decreased(P<0.01). There were 882 differentially expressed mRNAs in the testicular tissues, of which 565 were up-regulated and 317 were down-regulated. Cluster analysis showed that these differentially expressed mRNA could effectively distinguish between the sham-operated group and the model group. Compared with the model group, the damage to testicular tissue in the Wuzi Yanzongwan group was reduced, the structure of the seminiferous tubules was intact, vacuolization was reduced, and the number of spermatogenic cells at all levels was significantly increased and arranged tightly. The serum T significantly increased, LH significantly decreased(P<0.01), and FSH decreased but the difference was not statistically significant. The count and vitality of sperm in the epididymis were significantly increased(P<0.01). Moreover, Wuzi Yanzongwan could regulate 159 mRNA levels in the testes of semi-castrated mice, of which 32 were up-regulated and 127 were down-regulated, and the data of the transcriptome assay was verified to be reliable by Real-time PCR. GO and KEGG analysis showed that the transcriptome functions regulated by Wuzi Yanzongwan were involved in the whole cell cycle process of sperm development such as sex hormone production of interstitial cells in testis, renewal, differentiation, metabolism, apoptosis and signal transduction of spermatogenic cells, and were closely related to the biological behaviors of signaling pathways such as spermatogenic stem cell function, endoplasmic reticulum protein processing and metabolic program. ConclusionWuzi Yanzongwan can effectively improve the low spermatogenic function of semi-castrated male mice, and its mechanism may be related to the regulation of testicular transcriptional regulatory network, the synthesis of sex hormones in testicular interstitial cells, the function of spermatogenic stem cells, the whole cell cycle process of spermatogenesis, as well as the expression of endoplasmic reticulum protein processing and metabolic program related genes transcription.

Objective:To screen and verify the key radioresistance genes regulated by m6A methylation in nasopharyngeal carcinoma (NPC) based on the chip data and cell experiments.Methods:The microarray data of NPC radioresistance genes, m6A regulated genes and mRNA expression profiles of NPC genes were downloaded from Gene Expression Omnibus (GEO) database. The differential genes were screened and statistically analyzed by R software. The biological processes, signal pathways and interaction networks of these genes were analyzed by bioinformatics. The m6A regulatory factors were knocked down and the radioresistant strains were constructed. The above m6A differential radioresistant genes of NPC were screened and verified by real-time reverse transcription PCR (qRT-PCR) and Western blot. The m6A modification of screened genes and their direct binding ability with methyltransferase 3 (METTL3) were verified by methylated RNA immunoprecipitation qPCR (MeRIP-qPCR). The siRNA of selected genes was transfected into NPC cells, and after treatment with ionizing radiation, cell proliferation was detected by CCK-8 assay and EdU, apoptosis and cell cycle were detected by flow cytometry, and radiosensitivity was detected by clone formation assay. The trend of differences in the abundance of Fe 2+ and lipid peroxidation between the control and EGLN3 knockdown groups after ionizing radiation treatment was compared by paired t-test. Results:Chip data GSE48501 intersected with GSE200792 and GSE53819 to obtain 6 differential genes, including EGLN3, FOSL2, ADM, JUN, VEGFA and PRDM1. The target genes of EGLN3 and FOSL2 were further screened by TNMplot and KMplot, etc. The mRNA of the target genes directly bound to METTL3 and were subjected to its mediated modification of m6A. The target genes were up-regulated in the parental cells after irradiation in a dose and time gradient manner, which were also significantly up-regulated in radioresistant cells. After EGLN3 and FOSL2 were down regulated, the proliferation activity of NPC cells was more significantly decreased after irradiation, and the radiosensitization ratio was statistically significant compared with that of NPC cells without EGLN3 and FOSL2 down-regulation. After irradiation, EGLN3 down-regulated NPC cells significantly down-regulated glutathione peroxidase 4 (GPX4) expression, increased the abundance of Fe 2+ and lipid peroxidation, which played a role in radiosensitization by inducing ferroptosis. Conclusions:EGLN3 and FOSL2 play a role in radioresistance in NPC through METTL3 mediated m6A methylation. Down-regulation of EGLN3 combined with ionizing radiation can increase the intracellular Fe 2+ abundance and lipid peroxidation and down-reuglate the expression of GPX4 in NPC cells, which can enhance radiosensitization for NPC radiotherapy by the ferroptosis pathway.

Objectives:To compare the effects of manual and mechanical chest compression on patients receiving extracorporeal cardiopulmonary resuscitation (ECPR).Methods:Patients who underwent extracorporeal cardiopulmonary resuscitation admitted to Jinhua Municipal Central Hospital, Hangzhou First People's Hospital and the First Hospital of Jiaxing from September 2014 to July 2022 were enrolled in the study. The patients were divided into the manual group and mechanical group according to the compression method, and the clinical data of the two groups were compared. To explore the effects of the two compression method on the ECPR implementation, proportion of return of spontaneous circulation (ROSC) and hospital survival.Results:A total of 108 patients who underwent ECPR were included in the study, 50 patients in the manual group and 58 patients in the mechanical group. There were no significant differences in sex, age, laboratory tests before ECPR, ROSC proportion (90.0% vs. 86.2%) and survival (34.0% vs. 39.7%) between the two groups (all P>0.05). The puncture time in the mechanical group was shorter than that in the manual group [12 (9,15) min vs. 13 (11,16) min, P<0.05]. Conclusions:Compared with manual compression, mechanical compression during ECPR neither increase the probability of ROSC nor reduce in-hospital mortality in patients with cardiac arrest. However, mechanical compression may help to shorten the puncture time.

Résumé
Objective:To evaluate the disease burden (number of patients and characteristics of disease) and unmet medical needs (current status and inadequacy of medical treatment) in Chinese patients with moderate-to-severe psoriasis (msPsO) .Methods:High-quality real-world evidence on Chinese msPsO patients was sorted and reviewed in the MEDLINE, EMBASE, Web of Science, Wanfang, VIP, and CNKI databases from January 1st, 2012 to August 31st, 2022. The disease burden as well as challenges and shortcomings of systemic therapeutic drugs were analyzed in Chinese msPsO patients.Results:In China, msPsO patients made up a high proportion (67.0%) of psoriasis patients, and the number was estimated to be about 5 million. They were characterized by high severity of disease (the mean psoriasis area and severity index score of 16.3 points), large affected body surface area (22.1%), a high proportion of scalp psoriasis (63.1%), and high prevalence of comorbid metabolic syndrome (21.2%). Current evidence suggested that traditional oral therapeutic drugs were still challenged by limited efficacy and a high risk of adverse reactions, whereas patients showed relatively high rates (58.7% - 91.2%) of 75% improvement in psoriasis area and severity index (PASI75) response after 12-week treatment with biological agents; however, discontinuation of biological therapies was common after 52 weeks (15.0% - 54.2%), and the main reason was the lack of efficacy (8.3% - 31.4%), followed by economic pressures (5.6% - 19.0%) and adverse reactions (2.3% - 4.8%) .Conclusion:The number of Chinese msPsO patients is relatively large, and there is an urgent need for new effective, durable, safe, and easily usable drugs to meet the demand for long-term therapeutic management of msPsO.

Résumé
BACKGROUND@#Rapid on-site evaluation (ROSE) is a technique used for simultaneous evaluation of biopsy specimens through rapid cytology staining. Diff-Quik (DQ) staining is the most commonly employed method for cytological rapid on-site evaluation (C-ROSE). However, the utilization of DQ staining for on-site cytological interpretation remains uncommon among pathologists in China, posing challenges to the implementation of C-ROSE. This study aims to assess the application of rapid hematoxylin-eosin (HE) staining and DQ staining for C-ROSE during percutaneous needle biopsy of peripheral lung cancer and evaluate the value of rapid HE staining in C-ROSE.@*METHODS@#Computed tomography (CT)-guided lung biopsies were conducted on 300 patients diagnosed with peripheral lung cancer. The patients were randomly assigned to two groups for C-ROSE using either rapid HE staining or DQ staining, and subsequently the two methods were compared and evaluated.@*RESULTS@#The concordance rate between C-ROSE and histopathological diagnosis was 96.7%. The median staining time for rapid HE staining was 160 s, while that for DQ staining was 120 s, representing a significant difference between the two groups (P<0.001). However, there were no significant differences observed in terms of total biopsy time, concordance rate with histopathology, cytology specimen peeling rate, and incidence of serious adverse reactions between the two groups (P>0.05).@*CONCLUSIONS@#Both staining methods comply with C-ROSE criteria in the biopsy setting of peripheral lung cancer. Rapid HE staining is more aligned with domestic clinical requirements and holds potential for further promotion and adoption in C-ROSE.

Fibroblast growth factors (FGF) are a group of structurally related polypeptides which constitute an elaborate signaling system with their receptors. Evidence accumulated in the years suggests that the FGF family plays a key role in the repair of central nervous system injury. The main protective mechanisms include activating the expression of PI3K-Akt, peroxisome proliferator-activated receptor (PPARγ) and other signals; inhibiting NF-κB-mediated inflammatory response, oxidative stress and apoptosis; regulating neuronal differentiation and neuronal excitability as well as participating in protection of neurovascular units and nerve function repair. This paper comprehensively summarizes the latest research progress in FGF signaling related to diseases of the central nervous system such as cerebral infarction, cerebral hemorrhage, traumatic brain injury, Alzheimer's disease, Parkinson's disease, epilepsy and depression, aiming to provide scientific basis and reference for the development of innovative FGF drugs for the prevention and treatment of neurological diseases.

To explore the effect of education picture of standardized position in patients undergoing gastroscopy in awake state, 80 patients who underwent gastroscopy in Beijing Friendship Hospital from April 2022 to May 2022 were prospectively selected and divided into two groups by random number method, with 40 cases in experimental group and 40 cases in control group. Patients in control group received traditional conduction before gastroscopy, while patients in experimental group received picture education with standardized position based on the traditional method. The time of position placement, the time of gastroscopy, patient satisfaction, operator satisfaction and the occurrence of related adverse reactions between the two groups were recorded and compared. The results showed that the time of body position placement was 38.70±3.09 seconds in the experimental group and 50.25±3.12 seconds in the control group with statistical difference ( t=-16.637, P<0.001). The time of gastroscopy in the experimental group was 11.63±1.51 min, while that in the control group was 15.53±1.69 min, with statistical difference ( t=-10.856, P<0.001). Patient satisfaction was 92.5% (37/40) in the experimental group and 65.0% (26/40) in the control group, and operator satisfaction was 90.0% (36/40) and 67.5% (27/40) in the experimental group and the control group, respectively. The differences were both statistically significant ( P=0.005, P=0.027). Postoperative nausea occurred in 1 case in the experimental group, while 9 cases in the control group ( P=0.014). Using education picture of standardized position in patients before undergoing gastroscopy can shorten the time of position placement and gastroscopy, improve the satisfaction of patients and physicians, and reduce the occurrence of adverse events.
Résumé
Intermittent hypoxia (IH) is an important pathophysiological feature of obstructive sleep apnea (OSA), but its molecular mechanism is still unclear. We aim to investigate the role of endogenous competing endogenous RNA (ceRNA) regulatory network in the development of IH in OSA rats. An intermittent hypoxic rat model of OSA was constructed by hypoxic and reoxygenation cycles. CircRNAs and mRNAs were detected in rat bronchial tissues, and 230 up-regulated and 181 down-regulated circRNAs and 1238 up-regulated and 608 down-regulated mRNAs were analyzed and screened. The results of Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of the differential circRNAs and mRNAs suggested that they were mainly associated with metabolic pathways and PI3K-Akt signaling pathways. The key circRNAs (the top six circRNAs with the largest differences) were further validated by quantitative real-time polymerase chain reaction (qRT-PCR), chr9:52042693| 52047844 and chr4: 64889575|64899587 were expressed in bronchial tissues consistent with the sequencing results, which were used to further construct the ceRNA regulatory network. Four potential ceRNA regulatory networks were identified by TargetScan and miRanda database, combined with the results of differential circRNA and mRNA. The expression of molecules in the four potential ceRNA regulatory networks was detected by qRT-PCR in bronchial and lung tissues, and the results suggested that the expression of this regulatory network, chr9:52042693|52047844-miR-351-5p-Pten, was consistent with the sequencing results. The findings indicate that chr9:52042693 | 52047844-miR-351-5p-Pten may be involved in the development and progression of obstructive sleep apnea syndrome through a ceRNA mechanism.

Objective:To summarize the efficacy and safety of transurethral partial cystectomy combined with intravesical suturation in the treatment of bladder cancer.Methods:The clinical data of 28 patients with bladder cancer who were admitted in Zhengzhou People's Hospital from July 2020 to October 2021 were analyzed retrospectively. There were 22 males and 6 females, with the average age of (68.8±8.9) years old. Twenty cases were with single bladder tumor, and 8 cases were with multiple bladder tumors. The diameter of single bladder tumor measured by CT was less than 4 cm, with a median tumor diameter of 2.3(0.9, 2.8)cm. All 28 patients underwent transurethral partial cystectomy combined with intravesical suturation for the first time. Intraoperative intravesical instillation was conducted with 1 g gemcitabine. Bladder hot reperfusion treatment was performed with gemcitabine 2 g at 45℃ immediately after operation. The patients underwent reexamination with cystoscopy every 3 months after operation.Results:All the 28 patients successfully completed the operation. The average operation time was (128.3±16.3)min. No obturator nerve reflection was induced during operation. Muscularis tissue was found in all tumor pathological specimens after operation, among which 4 cases showed muscularis infiltration. Pathology of tumor basal and peripheral tissues showed tumor cell infiltration in 3 cases (1 case full-thickness infiltration, namely the incision margin was positive). The median continuous irrigation time of bladder after operation was 24.0(20.9, 25.0)h. The median time of indwelling catheter after operation was 6.5(6.0, 7.0)days, and one case developed severe bladder spasm. All patients were followed up, with a median follow-up of 7.5(4.0, 10.8) months.Postoperative recurrence occurred in 3 cases, all of which were ectopic recurrence in bladder.The 1-year recurrence rate was 10.7% (3/28).Conclusions:In the first surgical treatment of bladder cancer, transurethral partial cystectomy combined with intravesical suturation can provide accurate pathological staging, and low positive surgical margin rate. Immediate suturation of bladder wound during operation and immediate bladder perfusion chemotherapy can provide short bladder irrigation time, with few adverse reactions and low incidence of complications.
