Acupuncture for glaucoma-induced optic atrophy: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the clinical effect of acupuncture for glaucoma-induced optic atrophy.@*METHODS@#A total of 70 patients (89 affected eyes) with glaucoma-induced optic atrophy were randomized into an observation group and a control group, 35 cases in each group. The control group was given basic western medicine treatment. In the observation group, on the basis of the treatment in the control group, acupuncture was applied at main acupoints i.e. Baihui (GV 20), Shangjingming (Extra), Chengqi (ST 1), Fengchi (GB 20), Zusanli (ST 36), combined with supplementary acupoints based on syndrome differentiation, once every three days, twice a week. The treatment for 3 months was required in both groups. Before treatment, after treatment and in follow-up of 6 months after treatment, the best corrected visual acuity (BCVA), intraocular pressure (IOP), indexes of visual field (visual field index [VFI], mean deviation [MD], pattern standard deviation [PSD]) and mean thickness of retinal nerve fiber layer (RNFL) were observed in the two groups.@*RESULTS@#Compared before treatment, BCVA was decreased after treatment and in follow-up in the control group (P<0.05); in the follow-up, BCVA in the observation group was higher than that in the control group (P<0.05). On each time point before and after treatment, there was no significant difference within or between the two groups (P>0.05). After treatment and in the follow-up, the mean thickness of RNFL was larger than the control group (P<0.05).@*CONCLUSION@#On the basis of the basic western medicine treatment, acupuncture can delay the decline of vision and the thinning of retinal nerve fiber layer in patients with glaucoma-induced optic atrophy.

Clinical features and prognosis of high hyperdiploid childhood acute lymphoblastic leukemia: a multicenter retrospective analysis in Fujian Province, China / 中国当代儿科杂志

OBJECTIVES@#To study the clinical features and prognosis of high hyperdiploid (HHD) childhood acute lymphoblastic leukemia (ALL).@*METHODS@#A retrospective analysis was performed on the medical data of 1 414 children who were newly diagnosed with ALL and were admitted to five hospitals in Fujian Province of China from April 2011 to December 2020. According to karyotype, they were divided into two groups: HHD (n=172) and non-HHD (n=1 242). The clinical features and treatment outcome were compared between the two groups, and the factors influencing the prognosis were further explored.@*RESULTS@#Among the 1 414 children with ALL, 172 (12.16%) had HHD. Compared with the non-HHD group, the HHD group had significantly lower proportions of children with risk factors for poor prognosis at diagnosis (age of onset ≥10 years or <1 year, white blood cell count ≥50×109/L, and T-cell phenotype) or positive fusion genes (TEL-AML1, BCR-ABL1, E2A-PBX1, and MLL gene rearrangement) (P<0.05). The HHD group had a significantly higher proportion of children with minimal residual disease (MRD) <0.01% at the end of induction chemotherapy (P<0.05). The 10-year event-free survival (EFS) rate and overall survival (OS) rate in the HHD group were significantly higher than those in the non-HHD group (P<0.05). The univariate analysis showed that the number of chromosomes of 58-66, trisomy of chromosome 10, trisomy of chromosome 17, bone marrow MRD <1% on day 15 or 19 of induction chemotherapy, and bone marrow MRD <0.01% on day 33 or 46 of induction chemotherapy were associated with a higher EFS rate (P<0.05), and trisomy of chromosome 10 was associated with a higher OS rate (P<0.05). The multivariate Cox analysis showed that trisomy of chromosome 17 was closely associated with a high EFS rate (P<0.05).@*CONCLUSIONS@#The ALL children with HHD have few risk factors for poor prognosis at diagnosis and often have good prognosis. The number of chromosomes and trisomy of specific chromosomes are associated with prognosis in these children.

Screening of the ubiquitin-proteasome system activators for anti-Alzheimer's disease by the high-content fluorescence imaging system / 中国天然药物

Ubiquitin-proteasome system (UPS) plays an important role in neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). The discovery of UPS activators for anti-neurodegenerative diseases is becoming increasingly important. In this study, we aimed to identify potential UPS activators using the high-throughput screening method with the high-content fluorescence imaging system and validate the neuroprotective effect in the cell models of AD. At first, stable YFP-CL1 HT22 cells were successfully constructed by transfecting the YFP-CL1 plasmid into HT22 cells, together with G418 screening. The degradation activity of the test compounds via UPS was monitored by detecting the YFP fluorescence intensity reflected by the ubiquitin-proteasome degradation signal CL1. By employing the high-content fluorescence imaging system, together with stable YFP-CL1 HT22 cells, the UPS activators were successfully screened from our established TCM library. The representative images were captured and analyzed, and quantification of the YFP fluorescence intensity was performed by flow cytometry. Then, the neuroprotective effect of the UPS activators was investigated in pEGFP-N1-APP (APP), pRK5-EGFP-Tau P301L (Tau P301L), or pRK5-EGFP-Tau (Tau) transiently transfected HT22 cells using fluorescence imaging, flow cytometry, and Western blot. In conclusion, our study established a high-content fluorescence imaging system coupled with stable YFP-CL1 HT22 cells for the high-throughput screening of the UPS activators. Three compounds, namely salvianolic acid A (SAA), salvianolic acid B (SAB), and ellagic acid (EA), were identified to significantly decrease YFP fluorescence intensity, which suggested that these three compounds are UPS activators. The identified UPS activators were demonstrated to clear AD-related proteins, including APP, Tau, and Tau P301L. Therefore, these findings provide a novel insight into the discovery and development of anti-AD drugs.

Sperm-specific protein ACTL7A as a biomarker for fertilization outcomes of assisted reproductive technology / 亚洲男科学杂志(英文版)

Obtaining high-quality embryos is one of the key factors to improve the clinical pregnancy rate of assisted reproductive technologies (ART). So far, the clinical evaluation of embryo quality depends on embryo morphology. However, the clinical pregnancy rate is still low. Therefore, new indicators are needed to further improve the evaluation of embryo quality. Several studies have shown that the decrease of sperm-specific protein actin-like 7A (ACTL7A) leaded to low fertilization rate, poor embryo development, and even infertility. The aim of this study was to study whether the different expression levels of ACTL7A on sperm can be used as a biomarker for predicting embryo quality. In this study, excluding the factors of severe female infertility, a total of 281 sperm samples were collected to compare the ACTL7A expression levels of sperms with high and low effective embryo rates and analyze the correlation between protein levels and in-vitro fertilization (IVF) laboratory outcomes. Our results indicated that the ACTL7A levels were significantly reduced in sperm samples presenting poor embryo quality. Furthermore, the protein levels showed a significant correlation with fertilization outcomes of ART. ACTL7A has the potential to be a biomarker for predicting success rate of fertilization and effective embryo and the possibility of embryo arrest. In conclusion, sperm-specific protein ACTL7A has a strong correlation with IVF laboratory outcomes and plays important roles in fertilization and embryo development.

Objective:To investigate the effect of iron nanoparticles and melatonin on yield and quality of <italic>Fritillaria przewalskii</italic> and provide technical support for its domesticated cultivation. Method:Hundred grain weight was measured by conventional method；alkaloid content was detected according to protocols of the edition of 2020 <italic>Chinese Pharmacopoeia</italic>，chlorophyll，hydrogen peroxide，malondialdehyde，superoxide dismutase （SOD），peroxidase （POD） and catalase （CAT） were detected by spectrophotometric analysis，auxins，cytokinins，gibberellins，salicylic acid，jasmonic acid and abscisic acid were detected by ultra performance liquid chromatography tandem mass spectrometry analysis. Result:Zero-valent iron nanoparticles and melatonin significantly increased the hundred grain weight without affecting the quality. The effect of the two treatments on physiological and biochemical indexes in different stages were quite different，but the effects on content of endogenous hormones were basically the same. Correlation analysis showed that hundred grain weight was negatively correlated with malondialdehyde content，SOD activity and jasmonic acid content，but positively correlated with POD activity，salicylic acid content，gibberellins content，auxin content and abscisic acid content. The two treatments were separated effectively by principal component analysis，indicating that there were some differences in the mechanisms of growth promoting. The treatment of zero-valent iron nanoparticles mainly affected auxins，salicylic acid and abscisic acid. The treatment of melatonin mainly affected SOD，malondialdehyde and gibberellins. Conclusion:Zero-valent iron nanoparticles and melatonin can be used as a simple and practical technology to improve the stress resistance and yields of <italic>F. przewalskii</italic> in domesticated cultivation conditions.

Analysis of the related factors of fever of unknown causes before operation of intertrochanteric fracture in the elderly / 中国骨伤

OBJECTIVE@#To explore the related factors of fever of unknown causes before operation of intertrochanteric fracture of femur in the elderly.@*METHODS@#From August 2015 to August 2018, 156 cases of intertrochanteric fracture of femur were treated by intramedullary nail fixation. According to the preoperative measurement, whether there was fever was divided into fever group and non fever group. There were 80 cases in fever group, 26 males and 54 females, aged 60 to 93 (75.063±13.082) years; 76 cases in non fever group, 39 males and 37 females, aged 60 to 96 (74.763±13.692) years. All patients' sex, age, basic diseases, WBC, NE%, Hb, CRP, D dimer and ALB were observed for single factor analysisand multi factor analysis.@*RESULTS@#Single factor analysis showed that gender, Hb, CRP had influence on preoperative fever, but other indexes had no influence; multi factor analysis showed that gender and CRP might have influence on fever. The probability of fever increased by 1.2%(=0.050) for every increase of CRP, and there was no significant difference between female and male in the probability of fever (=0.061).@*CONCLUSION@#CRP is an independent risk factor of preoperative fever in the elderly patients with intertrochanteric fracture of femur. The abnormality of CRP indicates that patients are more likely to have preoperative fever. Perioperative management should pay attention to the monitoring of CRP and early intervention.

Interaction between homologous functional food Astragali Radix and intestinal flora / 中国中药杂志

Traditional Chinese medicine(TCM) is the treasure of our culture, and TCM theory is the core of traditional Chinese medicine. Many of its concepts can be unified and balanced with modern functional food ideas. Even in ancient days, people had already found that medicine and food have the same source. Nowadays, homology between drug and food has been accepted widely. Astragali Radix and some other herbs have been used both as food and medicine, with a variety of bio-active substances, so such herbs can be used as characteristics resources to be developed into functional food. It's a combination of traditional medicine and modern ideas. Flavonoids, polysaccharides and saponins, the main compositions of Astragali Radix, can keep intestinal microenvironment homeostasis and human health by influencing the population structure, metabolism and intestinal cell function of intestinal flora. On the other hand, intestinal flora is also involved in the absorption, metabolism, transformation and other steps of these active ingredients in the body, which has an impact on their effectiveness and improves their bioavailability, playing an essential role in the relevant mechanism of their effectiveness. In this paper, we summarize the interaction between the above three functional ingredients in Astragali Radix and intestinal flora, sum up the interaction between these three functional ingredients of other homologous drugs and intestinal flora, provide a theoretical basis for the mechanism and application of functional food materials, and propose some suggestions and prospects for their future development.

Prohibitin (PHB) interacts with AKT in mitochondria to coordinately modulate sperm motility / 亚洲男科学杂志(英文版)

Prohibitin (PHB), an evolutionarily conserved mitochondrial inner membrane protein, is highly expressed in cells that require strong mitochondrial function. Recently, we demonstrated that the deletion of Phb in spermatocytes results in impaired mitochondrial function. In addition, PHB expression in the mitochondrial sheath of human sperm has a significantly negative correlation with mitochondrial reactive oxygen species levels, but a positive one with mitochondrial membrane potential and sperm motility. These results suggest that mitochondrial PHB expression plays a role in sperm motility. However, the mechanism of PHB-mediated regulation of sperm motility remains unknown. Here, we demonstrate for the first time that PHB interacts with protein kinase B (AKT) and exists in a complex with phospho-PHB (pT258) and phospho-AKT in the mitochondrial sheath of murine sperm, as determined using colocalization and coimmunoprecipitation assays. After blocking AKT activity using wortmannin (a phosphatidylinositol 3-kinase [PI3K] inhibitor), murine sperm have significantly ( P < 0.05) decreased levels of phospho-PHB (pT258) and the total and progressive motility. Furthermore, significantly ( P < 0.05) lower levels of phospho-PI3K P85 subunit α+γ (pY199 and pY467) and phospho-AKT (pS473; pT308) are found in sperm from infertile asthenospermic and oligoasthenospermic men compared with normospermic subjects, which suggest a reduced activity of the PI3K/AKT pathway in these infertile subjects. Importantly, these sperm from infertile subjects also have a significantly ( P < 0.05) lower level of phospho-PHB (pT258). Collectively, our findings suggest that the interaction of PHB with AKT in the mitochondrial sheath is critical for sperm motility, where PHB phosphorylation (pT258) level and PI3K/AKT activity are key regulatory factors.
