OBJECTIVE: To observe the short-term efficacy, long-term efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: Forty-two patients with CP/CPPS were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases). The patients in the acupuncture group were treated with acupuncture at bilateral Zhongliao (BL 33), Huiyang (BL 35), Shenshu (BL 23) and Sanyinjiao (SP 6); the needling depth of Zhongliao (BL 33) and Huiyang (BL 35) was 60 to 80 mm, while Shenshu (BL 23) and Sanyinjiao (SP 6) was directly punctured of 30 mm. The patients in the sham acupuncture group were treated with acupuncture at non-acupoints, including points 2 cm next to Shenshu (BL 23), Zhongliao (BL 33) and Huiyang (BL 35), and the midpoint of the connecting line between the spleen meridian and the kidney meridian. All the non-acupoints were treated with directly puncture of 2 to 3 mm. The needles were left for 30 min in both groups, once every other day in the first four weeks, three times a week, and twice a week in the next four weeks, totally 20 treatments. Before treatment, after treatment and in follow-up of 24 weeks after treatment completion, the National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) score and urinary flow rate were observed in both groups; the clinical efficacy and safety were evaluated. RESULTS: Compared with those before treatment, the pain and discomfort scores, urination symptoms scores, quality of life scores and total scores of NIH-CPSI in both groups were reduced after treatment in the two groups (P<0.01), while each item score and total score of NIH-CPSI in the acupuncture group were reduced in follow-up (P<0.01, P<0.05). After treatment and in follow-up, each item score and total score of NIH-CPSI in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). After treatment, the maximum and average urinary flow rates in the acupuncture group were higher than those before treatment (P<0.05), and the average urinary flow rate in the acupuncture group was higher than that in the sham acupuncture group (P<0.05). The total effective rate was 75.0% (15/20) in the acupuncture group, which was higher than 42.9% (9/21) in the sham acupuncture group (P<0.05). No significant adverse reactions were observed in the two groups, and there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). CONCLUSION Acupuncture could effectively alleviate the clinical symptoms, improve quality of life, and has a sustained, safe and reliable therapeutic effect in patients with CP/CPPS.

Sleep has attracted extensive attention due to its significance in health. However, its association with erectile dysfunction (ED) is insufficiently investigated. To investigate the potential causal links between sleep traits (insomnia, sleep duration, and chronotype) and ED, this study was performed. The single-nucleotide polymorphisms (SNPs) associated with insomnia, sleep duration, and chronotype were retrieved from previous genome-wide association studies (GWAS). A conventional two-sample Mendelian randomization (MR) was used to estimate the causal links between sleep traits and ED. The summary statistics of ED were from individuals of European ancestry (6175 cases vs 217 630 controls). As shown by the random effect inverse-variance-weighting (IVW) estimator, genetically predicted insomnia was causally associated with a 1.15-fold risk of ED (95% confidence interval: 1.07-1.23, P < 0.001). Sleep duration and morningness were not causally associated with ED, as indicated by the IVW (all P > 0.05). These findings were consistent with the results of sensitivity analyses. Based on genetic data, this study provides causal evidence that genetically predicted insomnia increases the risk of ED, whereas sleep duration and chronotype do not.

Literature regarding the impacts of heavy metal exposure on erectile dysfunction (ED) is scarce. We aimed to evaluate the correlation between 10 urinary metals and ED in a large, nationally representative adult male sample. The dataset was extracted from the National Health and Nutrition Examination Survey (NHANES) during the period of 2001-2002 and 2003-2004. Weighted proportions and multivariable logistic regression analysis adjusted for confounding variables were utilized to determine the relationship between metal exposure and ED. Weighted quantile sum (WQS) regression was utilized to evaluate the impact of a mixture of urinary metals on ED. A total of 1328 participants were included in our study. In multivariable logistic regression analysis, cobalt (Co) and antimony (Sb) were positively associated with ED (odds ratio [OR]: 1.36, 95% confidence interval [CI]: 1.10-1.73, P = 0.020; and OR: 1.41, 95% CI: 1.12-1.77, P = 0.018, respectively) after full adjustment. Men in tertile 4 for Co (OR: 1.49, 95% CI: 1.02-2.41, P for trend = 0.012) and Sb (OR: 1.53, 95% CI: 1.08-2.40, P for trend = 0.041) had significantly higher odds of ED than those in tertile 1. Furthermore, the WQS index was significantly linked with increased odds of ED after full adjustment (OR: 1.31, 95% CI: 1.04-1.72, P < 0.05). Our study expanded on previous literature indicating the possible role of heavy metal exposure in the etiology of ED. The evaluation of heavy metal exposure should be included in the risk assessment of ED.

OBJECTIVES: To investigate the clinical characteristics and risk factors for early-onset necrotizing enterocolitis (NEC) in preterm infants with very/extremely low birth weight (VLBW/ELBW). METHODS: A retrospective analysis was performed on the medical data of 194 VLBW/ELBW preterm infants with NEC who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2014 to December 2021. These infants were divided into early-onset group (onset in the first two weeks of life; n=62) and late-onset group (onset two weeks after birth; n=132) based on their onset time. The two groups were compared in terms of perinatal conditions, clinical characteristics, laboratory examination results, and clinical outcomes. Sixty-two non-NEC infants with similar gestational age and birth weight who were hospitalized at the same period as these NEC preterm infants were selected as the control group. The risk factors for the development of early-onset NEC were identified using multivariate logistic regression analysis. RESULTS: Compared with the late-onset group, the early-onset group had significantly higher proportions of infants with 1-minute Apgar score ≤3, stage III NEC, surgical intervention, grade ≥3 intraventricular hemorrhage, apnea, and fever or hypothermia (P<0.05). The multivariate logistic regression analysis showed that feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, and hemodynamically significant patent ductus arteriosus were independent risk factors for the development of early-onset NEC in VLBW/ELBW preterm infants (P<0.05). CONCLUSIONS VLBW/ELBW preterm infants with early-onset NEC have more severe conditions compared with those with late-onset NEC. Neonates with feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, or hemodynamically significant patent ductus arteriosus have a higher risk of early-onset NEC.

Penile length shortening and erectile dysfunction are common complications after radical prostatectomy. Various methods have been used to maintain erectile function, but less attention has been paid to preserving penis length. N-acetylcysteine (NAC) has the effect of antioxidation and antifibrotic, which may be beneficial to improve those postoperative complications. This study investigated the effect of NAC on maintaining the penile length and the erectile function after bilateral cavernous nerve crush (BCNC) and its underlying mechanism. Twenty-four male rats were randomly divided into three groups: control group, BCNC group, and BCNC + NAC group. NAC or equal volume of saline was daily administrated by intragastric gavage for 4 weeks. The initial and end penile lengths were measured. Intracavernosal pressure/mean arterial pressure (ICP/MAP) ratio was calculated to assess erectile function. Hematoxylin-eosin staining, Masson's trichrome staining, immunohistochemistry, and Western blot were performed to explore cellular and molecular changes of the penis. Compared to the BCNC group, the penile length, ICP/MAP ratio and smooth muscle/collagen ratio in the BCNC + NAC group were improved significantly (all P < 0.05), and the expressions of endothelial nitric oxide synthase, α-smooth muscle actin, glutathione, and glutathione peroxidase 1 were significantly increased after NAC treated (all P < 0.05), along with the decreased expressions of hypoxia-inducible factor-1α, transforming growth factor-β1, collagen I, collagen III, collagen IV, malonaldehyde, and lysine oxidase (all P < 0.05). This study demonstrated that NAC could maintain penile length and partly improve erectile function. Possible mechanism is directly and/or indirectly related to antihypoxic and antifibrosis.

Postprostatectomy erectile dysfunction (pPED) remains a current problem despite improvements in surgical techniques. Vacuum therapy is clinically confirmed as a type of pPED rehabilitation. However, its underlying mechanisms are incompletely understood. Recently, autophagy and apoptosis were extensively studied in erectile dysfunction resulting from diabetes, senescence, and androgen deprivation but not in the context of pPED and vacuum therapy. Therefore, this study was designed to investigate the roles of autophagy and apoptosis in pPED and vacuum therapy. Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: the control group, bilateral cavernous nerve crush (BCNC) group, and BCNC + vacuum group. After 4 weeks of treatment, intracavernosal pressure was used to evaluate erectile function. Real-time quantitative polymerase chain reaction, western blot, and immunohistochemistry were used to measure the molecular expression. TdT-mediated dUTP nick-end labeling staining was used to assess apoptosis. Transmission electron microscopy was used to observe autophagosomes. After treatment, compared with those of the BCNC group, erectile function and cavernosal hypoxia had statistically significantly improved (P < 0.05). Apoptosis and the relative protein expression of B-cell lymphoma-2-associated X and cleaved Caspase3 were decreased (P < 0.05). Autophagy-related molecules such as phosphorylated unc-51-like autophagy-activating kinase 1 (Ser757) and p62 were decreased. Beclin1, microtubule-associated protein 1 light chain 3 A/B, and autophagosomes were increased (P < 0.05). Besides, the phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin signaling pathway, as a negative regulator of autophagy to some degree, was inhibited. This study revealed that vacuum therapy ameliorated pPED in BCNC rats by inhibiting apoptosis and activating autophagy.

Lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) and depression are both increasing in Chinese aging males. However, the relationship still remains unknown. To explore their relationship, a retrospective cohort study based on propensity score matching (PSM) was conducted by analyzing the China Health and Retirement Longitudinal Study dataset. After data cleaning, a total of 5125 participants were enrolled and subjected to PSM; 1351 pairs were matched and followed for 2 years. Further logistic regression and restricted cubic spline (RCS) were performed to evaluate, model and visualize the relationship between depression and LUTS/BPH. Moreover, subgroup analyses and sensitivity analyses were adopted to verify the robustness of the conclusions. Before PSM, depressive patients showed higher odds of LUTS/BPH in all three models adjusting for different covariates (P < 0.001). After PSM, univariate logistic regression revealed that depressive patients had higher risks for LUTS/BPH than participants in the control group (odds ratio [OR] = 2.10, P < 0.001). The RCS results indicated a nonlinear (P < 0.05) and inverted U-shaped relationship between depression and LUTS/BPH. In the subgroup analyses, no increased risks were found among participants who were not married or cohabitating, received an education, had an abnormal body mass index (<18.5 kg m

To clarify the difference of soil moisture characteristics between mixed broad leaf-conifer forest soil and artificial cultivation of Notopterygium incisum, the HYPROP system and the dew point potential meter were used to determine soil water retention curves(SWRC) for samples of two horizons(i.e. 2-7 cm, 10-15 cm). The basic physical and chemical properties of soil and its water characteristic parameters were also determined. The result showed as fllows:①The bulk density of mixed coniferous-broad leaf forest soil was between 0.33 and 0.52 g·cm~(-3), significantly lower than the corresponding value of field soil(1.01-1.18 g·cm~(-3))(P<0.05), While the organic matter content was significantly higher than the corresponding value of field soil(P<0.05). ②The saturated water content(θ_s), field water holding capacity(θ_(FC)) and Water that can be effectively utilized by plants(θ_(PAC)) of mixed coniferous-broadleaved forest soil were significantly higher than the corresponding value of field soil(P<0.05), while the retained water content(θ_r) value that cannot be effectively utilized by plants was significantly lower than that of field soil(P<0.05). ③The values of structural porosity(0.13-0.24 cm~3·cm~(-3)) and Matrix porosity(0.34-0.44 cm~3·cm~(-3)) of mixed coniferous-broadleaved forest soil were higher than the corresponding values of field soil. Therefore, with low bulk density and high content of organic matter, mixed coniferous-broadleaved forest soil can store more water in soil in the form of effective water to meet the needs of plants for water, thus possibly forming high quality medicinal materials of Notopterygii Rhizoma et Radix. In conclusion, the results of this study can provide theoretical basis guidance for soil structure improvement and water management to form high quality medicinal materials in the artificial cultivation of N. incisum.

Study the growth and development process of rhizomes(bamboo-like part) of Notopterygium incisum and the changes of carbohydrate, endogenous hormones and secondary metabolites, and provide theoretical guidance for the formation of high-quality N. incisum medicinal commodities under artificial cultivation. The One-year-old seedlings were transplanted to the original habitat,and the growth and physiological characteristics of N. incisum were dynamically monitored. The results showed that: ① Seedlings transplanted to the original habitat in spring could form rhizomes(bamboo-like part) in the same year. ② After 60 days of transplantation, the root length and root diameter of underground part of N. incisum had increased rapidly, and carbohydrate content in roots and rhizomes had accumulated rapidly. After 120 days of transplantation, the roots and rhizomes of underground part had grown slowly, and starch content in roots and rhizomes increased continuously, while sucrose and total soluble sugar content decreased gradually. ③ The content of abscisic acid(ABA) in rhizomes decreased firstly and then increased, while the indole acetic acid(IAA) content stabilized firstly and then increased rapidly, and the contents of gibberellin(GA_3) and zeatin riboside(ZR) continued to increase. ④ The content of notopterol in rhizomes was higher than that in roots, while the content of isoimperatorin was lower than that in roots, but the total content of the both in rhizomes was higher than that in roots. Therefore, N. incisum can form rhizomes with high content of secondary metabolites under wild tending, and the growth and development of rhizomes are closely related to changes in carbohydrates and are regulated by related endogenous hormones.
