Objective To examines the correlation between lifestyle factors and semen quality among sperm donors at Anhui human sperm bank.Methods Demographic and lifestyle data were collected from 1,222 volunteers who donated sperm between January 2021 and December 2023,and their association with semen quality was analyzed.Results Univariate chi-square analysis revealed significant associations between several lifestyle factors and abnor-mal semen parameters(P＜0.05),including non-student status,frequent masturbation,short-term abstinence,low exercise frequency,frequent staying up late,smoking,drinking,and short sleep duration.Moreover,multiva-riate logistic regression analysis demonstrated that non-student status,longer abstinence time,and insufficient sleep were linked to abnormal semen volume.Additionally,abstinence time,exercise frequency,staying up late,smok-ing,and sleep duration were significantly correlated with abnormal semen concentration and sperm motility(P＜0.05).Conclusion Analysis reveals a close relationship between semen quality and volunteers'lifestyles,inclu-ding factors such as abstinence time,staying up late,sleep duration,smoking,drinking,and exercise frequency.

Objective: To investigate the causative factors of renal function in newly diagnosed multiple myeloma (MM) patients with renal inadequacy. Methods: 181 MM patients with renal impairment from August 2007 to October 2021 at Peking Union Medical College Hospital were recruited, whose baseline chronic kidney disease (CKD) stage was 3-5. Statistical analysis was performed based on laboratory tests, treatment regimens, hematological responses, and survival among various renal function efficacy groups. A logistic regression model was employed in multivariate analysis. Results: A total of 181 patients were recruited, and 277 patients with CKD stages 1-2 were chosen as controls. The majority choose the BCD and VRD regimens. The progression-free survival (PFS) (14.0 months vs 24.8 months, P<0.001) and overall survival (OS) (49.2 months vs 79.7 months, P<0.001) of patients with renal impairment was considerably shorter. Hypercalcemia (P=0.013, OR=5.654) , 1q21 amplification (P=0.018, OR=2.876) , and hematological response over a partial response (P=0.001, OR=4.999) were independent predictive factors for renal function response. After treatment, those with improvement in renal function had a longer PFS than those without (15.6 months vs 10.2 months, P=0.074) , but there was no disparity in OS (56.5 months vs 47.3 months, P=0.665) . Conclusion: Hypercalcemia, 1q21 amplification, and hematologic response were independent predictors of the response of renal function in NDMM patients with renal impairment. MM patients with CKD 3-5 at baseline still have worse survival. Improvement in renal function after treatment is attributed to the improvement in PFS.

Objective: To establish and validate a nomogram-based predictive model for idiopathic hyperaldosteronism (IHA). Methods: This cross-sectional study was conducted with the collected clinical and biochemical data of patients with primary aldosteronism (PA) including 249 patients with unilateral primary aldosteronism (UPA) and 107 patients with IHA, who were treated at the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to November 2022. Plasma aldosterone concentration (PAC) and plasma renin concentration (PRC) were measured by chemiluminescence. Stepwise regression analysis was applied to select the key predictors of IHA, and a nomogram-based scoring model was developed. The model was validated in another external independent cohort of patients with PA including 62 patients with UPA and 43 patients with IHA, who were diagnosed at the Department of Endocrinology, First Affiliated Hospital of Zhengzhou University. An independent-sample t test, Mann-Whitney U test, and χ² test were used for statistical analysis. Results: In the training cohort, in comparison with the UPA group, the IHA group showed a higher serum potassium level [M(Q₁, Q₃), 3.4 (3.1, 3.8) mmol/L vs. 2.7 (2.1, 3.1) mmol/L] and higher PRC [4.0 (2.1, 8.2) mU/L vs. 1.5 (0.6, 3.4) mU/L] and a lower PAC post-saline infusion test (SIT) [305 (222, 416) pmol/L vs. 720 (443, 1 136) pmol/L] and a lower rate of unilateral adrenal nodules [33.6% (36/107) vs. 81.1% (202/249)]; the intergroup differences in these measurements were statistically significant (all P<0.001). Serum potassium level, PRC, PAC post-SIT, and the rate of unilateral adrenal nodules showed similar performance in the IHA group in the validation cohort. After stepwise regression analysis for all significant variables in the training cohort, a scoring model based on a nomogram was constructed, and the predictive parameters included the rate of unilateral adrenal nodules, serum potassium concentration, PAC post-SIT, and PRC in the standing position. When the total score was ≥14, the model showed a sensitivity of 0.65 and specificity of 0.90 in the training cohort and a sensitivity of 0.56 and specificity of 1.00 in the validation cohort. Conclusion: The nomogram was used to successfully develop a model for prediction of IHA that could facilitate selection of patients with IHA who required medication directly.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective:To investigated the efficacy and safety of transurethral bladder neck incision and laparoscopic modified bladder neck Y-V plasty in the treatment of bladder neck contracture (BNC)after transurethral resection of prostate (TURP).Methods:The clinical data of 57 patients with BNC after TURP who were treated in the Department of Urology, Sixth People's Hospital, Shanghai Jiaotong University School of Medicine from January 2013 to December 2022 were retrospectively analyzed.And the patients were divided into two groups based on the different surgical approaches. There were 22 cases in the transurethral bladder neck incision group, with an average age of (73.75±7.62) years and the preoperative urinary flow Q max of (3.92±2.73) ml/s. The preoperative International Prostate Symptom Score (IPSS) was (26.92±3.34) points, and the quality of life (QOL) score was (4.83±0.72) points. There were 35 cases in laparoscopic modified bladder neck Y-V plasty group, with an average age of (68.57±9.31) years and the preoperative urinary flow Q max of (2.56±1.27)ml/s. The preoperative IPSS was (27.08±3.06) points, and the QOL score was (5.08±0.84) points. The patients underwent transurethral bladder neck incision: Scar tissue was incised at 3, 9, and 12 o'clock in the bladder neck, and the incision depth reached the external fat of the bladder neck at 3 and 9 o'clock. Patients with significantly elevated bladder neck were treated with plasma electrosurgical resection to remove scar tissue. The patients underwent laparoscopic modified bladder neck Y-V plasty: After proper exposition of the bladder neck, the scar tissue was excised. the anterior bladder wall was incised in an inverted Y-shaped manner, the apex of the V-shaped flap was sutured to the distal urethrotomy to create a widened bladder neck. The postoperative urinary flow Q max, IPSS, and QOL of the two groups were compared. Results:All patients underwent surgeries successfully, with a one-time success rate of 94.3% (33/35) in the laparoscopic modified bladder neck Y-V plasty group, which was higher than the one-time success rate of 68.2% (15/22) in the transurethral bladder neck incision group( P<0.01). There were statistically significant difference in operation time [(31.75±12.81)min vs. (68.57±22.36)min] and postoperative hospital stay [(1.73±0.94)d vs. (5.17±2.12)d] between the transurethral bladder neck incision group and the laparoscopic modified bladder neck Y-V plasty group ( P<0.05). The median follow-up period was 12.6 (7.3, 27.8) months. The IPSS of the transurethral bladder neck incision group and the laparoscopic modified bladder neck Y-V plasty group were (9.92±2.56) points and (7.16±2.21) points, respectively. The QOL was (2.76±1.24) points and (1.31±0.95) points, respectively. The urinary flow Q max at 6 months after operation was (15.13±4.68)ml/s and (19.96±4.17)ml/s, respectively. There was statistical significance( P<0.05). Conclusions:Both laparoscopic modified bladder neck Y-V plasty and transurethral bladder neck incision are safe and effective in the treatment of BNC after TURP, and laparoscopic modified bladder neck Y-V plasty has a better clinical therapeutic effect.

Morinda officinalis oligosaccharides (MOO) are an oral drug approved in China for the treatment of depression in China. However, MOO is hardly absorbed so that their anti-depressant mechanism has not been elucidated. Here, we show that oral MOO acted on tryptophan → 5-hydroxytryptophan (5-HTP) → serotonin (5-HT) metabolic pathway in the gut microbiota. MOO could increase tryptophan hydroxylase levels in the gut microbiota which accelerated 5-HTP production from tryptophan; meanwhile, MOO inhibited 5-hydroxytryptophan decarboxylase activity, thus reduced 5-HT generation, and accumulated 5-HTP. The raised 5-HTP from the gut microbiota was absorbed to the blood, and then passed across the blood-brain barrier to improve 5-HT levels in the brain. Additionally, pentasaccharide, as one of the main components in MOO, exerted the significant anti-depressant effect through a mechanism identical to that of MOO. This study reveals for the first time that MOO can alleviate depression via increasing 5-HTP in the gut microbiota.

The present study was aimed to investigate the effects of circRNA-0028171 on the apoptosis of vascular endothelial cells induced by arsenic trioxide (As₂O₃). Human umbilical vein endothelial cells (HUVECs) were treated with 0-15 μmol/L As₂O₃ for 24 h. Then, cellular viability was measured by MTT assay. The expression levels of circRNA-0028171, Bcl-2 and Bax mRNA were detected by real-time quantitative PCR. Bcl-2/Bax protein ratio was detected by Western blot. Whether circRNA-0028171 was involved in the regulation of HUVECs by As₂O₃ was investigated by transfection with overexpression plasmid of circRNA-0028171 and siRNA. The results showed that compared with the control group, As₂O₃ group showed decreased cellular viability, reduced Bcl-2/Bax mRNA and protein ratios, and significantly lower expression of circRNA-0028171. Overexpression of circRNA-0028171 inhibited apoptosis of HUVECs induced by As₂O₃. Knockdown of circRNA-0028171 by siRNA promoted As₂O₃-induced apoptosis in HUVECs. These results suggest that circRNA-0028171 is involved in the vascular endothelial cell apoptosis induced by As₂O₃.

Idiopathic asthenozoospermia, a common factor in male infertility, is characterized by altered sperm motility function in fresh ejaculate. Although the β-defensin 126 (DEFB126) protein is associated with asthenozoospermia, DEFB126 gene polymorphisms have not been extensively studied. Therefore, the association between DEFB126 gene polymorphisms and asthenozoospermia requires further investigation. Screening was performed by semen analysis, karyotype analysis, and Y microdeletion detection, and 102 fertile men and 106 men with asthenozoospermia in Chengdu, China, were selected for DEFB126 gene sequence analyses. Seven nucleotide mutations and two nucleotide deletions in the DEFB126 gene were detected. rs11467417 (317-318 del/del), rs11467497 (163-166 wt/del), c.152T>C, and c.227A>G were significantly different between the control and asthenozoospermia groups, likely representing high-risk genetic factors for asthenozoospermia among males. DEFB126 expression was not observed in sperm with rs11467497 homozygous deletion and was unstable in sperm with rs11467417 homozygous deletion. The rs11467497 four-nucleotide deletion leads to truncation of DEFB126 at the carboxy-terminus, and the rs11467417 binucleotide deletion produces a non-stop messenger RNA (mRNA). The above deletions may be responsible for male hypofertility and infertility by reducing DEFB126 affinity to sperm surfaces. Based on in silico analysis, the amino acids 51M and 76K are located in the highly conserved domain; c.152T>C (M51T) and c.227A>G (K76R) are predicted to be damaging and capable of changing alternative splice, structural and posttranslational modification sites of the RNA, as well as the secondary structure, structural stability, and hydrophobicity of the protein, suggesting that these mutations are associated with asthenozoospermia.

Objective    To investigate the safety and effectiveness of the multi-artery graf tstrategy for coronary bypass (MICS-CABG) with small incision in the left chest, and to provide experience for the promotion of this technique. Methods    The clinical data of 64 patients with MICS-CABG in Department of Cardiac Surgery of Peking University Third Hospital from December 2015 to November 2019 were retrospectively analyzed. There were 54 males and 10 females, aged 36-77 (61.1±8.7) years. The left lateral thoracic incision (5-8 cm) was made through the 5th intercostal incision, and the operation was performed under off-pump CABG. With the help of the chest wall suspension device and the heart fixator, the proximal anastomosis of the ascending aorta, anastomosis of the target vessels of the left anterior descending (LAD), left circumflex (LCX) and right coronary artery (RCA) systems were completed. The number of grafts was 2-4 (2.3±0.5) including 2 grafts in 45 patients, 3 grafts in 17 patients and 4 grafts in 2 patients. Three patients were treated with percutaneous intervention (PCI) hybridization and 62 patients were treated with total artery bypass graft. Coronary angiography was performed within 7 days after the operation to evaluate the graft patency rate. The incidence of major adverse cardiac and cerebrovascular events (MACCE) was recorded in the follow-up. The MACCE rate was calculated by Kaplan-Meier method. Results    None of the patients was transferred to thoracotomy and no intra-aortic balloon counterpulsation (IABP) or extracorporeal membrane oxygenation (ECMO) was used during the operation.  Incision infection was in 1 patient and reoperation in 2 patients (all were postoperative hemorrhage). Within 30 days after surgery, MACCE occurred in 1 patient, including 1 patient of non-fatal myocardial infarction. The overall patency rate of angiography bypass was 96.2%, and the patency rate of anterior descending branch bypass was 98.2%. Follow-up was performed from 12 to 60 months (median follow-up time was 28 months). The loss rate was 7.8% (5/64). The incidence of MACCE was 84.9% (95%CI 79.5%-90.3%). Conclusion    The MICS-CABG can achieve completed re-vascularization and totally artery-CABG and the short-term and medium-term clinical results of the operation are good.
