Genetic pathogenesis of acephalic spermatozoa syndrome: past, present, and future / 亚洲男科学杂志(英文版)

Acephalic spermatozoa syndrome (ASS) is one of the most severe spermatogenic failures of all infertility in men. The cognition of ASS has experienced a tortuous process. Over the past years, with the in-depth understanding of spermatogenesis and the emergence of new genetic research technologies, the unraveling of the genetic causes of spermatogenic failure has become highly active. From these advances, we established a genetic background and made significant progress in the discovery of the genetic causes of ASS. It is important to identify pathogenic genes and mutations in ASS to determine the biological reasons for the occurrence of the disease as well as provide genetic diagnosis and treatment strategies for patients with this syndrome. In this review, we enumerate various technological developments, which have made a positive contribution to the discovery of candidate genes for ASS from the past to the present. Simultaneously, we summarize the known genetic etiology of this phenotype and the clinical outcomes of treatments in the present. Furthermore, we propose perspectives for further study and application of genetic diagnosis and assisted reproductive treatment in the future.

Effect of Didang Xianxiong Decoction on Cardiac Myocardial Microvascular Endothelial Cell Injury Induced by High Glucose / 中国实验方剂学杂志

ObjectiveThis study was designed to observe the effect of Didang Xianxiong decoction on the cardiac myocardial microvascular endothelial cells （CMECs） injury， and to explore its related mechanism based on the CMECs model induced by high glucose. MethodRat primary myocardial cells were cultured in vitro and 33 mmol·L-1 glucose was added for modeling. After modeling， the rats were randomly divided into model group （final glucose concentration： 33 mmol·L-1）， normal group， Didang Xianxiong decoction low dose group （glucose + 5% Didang Xianxiong decoction containing serum）， Didang Xianxiong decoction medium dose group （glucose+10% Didang Xianxiong decoction containing serum）， Didang Xianxiong decoction high dose group （glucose+20% Didang Xianxiong decoction containing serum） and alagebrium chloride （ALT-711） group （glucose+10% ALT-711 containing serum）. The influence of drug-containing serum on the proliferation of CMECs was detected by MTT tetrazolium salt colorimetric assay. The relative mRNA expression of c-Jun was detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The protein expression of phosphorylated Janus kinase 1 （p-JAK1）， phosphorylated signal transducer and activator of transcription 1 （p-STAT1） and transforming growth factor-β1 （TGF-β1） was determined by Western blot. ResultCompared with the conditions in normal group， the mRNA expression of c-Jun and protein expression of p-JAK1， p-STAT1 and TGF-β1 were up-regulated in model group （P<0.01）. Compared with model group， all treatment groups had decreased mRNA expression of c-Jun （P<0.01）. Didang Xianxiong decoction medium and high dose groups and ALT-711 group showed reduced protein expression of p-JAK1 and p-STAT1 （P<0.05， P<0.01）， while there was no significant change in Didang Xianxiong decoction low dose group. TGF-β1 protein expression was lowered in all treatment groups （P<0.05， P<0.01）， and the decrease was more significant in Didang Xianxiong decoction medium and high dose groups than Didang Xianxiong decoction low dose group. ConclusionDidang Xianxiong decoction can protect CMECs with high glucose-induced injury， and the mechanism may be related to reducing the activity of JAK/STAT signaling pathway in cells.

Objective:To observe the intervention of phlegm-stasis co-treatment on the myocardial Toll-like receptor 4 （TLR4）/nuclear factor-<italic>κ</italic>B （NF-<italic>κ</italic>B）/nuclear factor-<italic>κ</italic>B inhibitor （I<italic>κ</italic>B） signaling pathway， and to investigate its mechanism in improving myocardial inflammation in rats with diabetes mellitus （DM）. Method:Forty-five male SD rats of SPF grade were randomly divided into a normal group， a phlegm-resolving （Xiao Xianxiongtang， 4.05 g·kg^-1） group， a stasis-resolving （Xuefu Zhuyutang， 7.02 g·kg^-1） group， a co-treatment （Didang Xianxiong decoction， 8.10 g·kg^-1） group， an alagebrium chloride （3 mg·kg^-1） group， and a model group. Except for normal group， the other rats was induced by a single intraperitoneal injection of 55 mg·kg^-1streptozotocin （STZ） to establish DM model. After adaptive feeding for three weeks， the rats were treated correspondingly by gavage daily for eight weeks. Rats were sampled under anesthesia. Enzyme-linked immunosorbent assay（ELISA） was used to detect the protein expression of TLR4 and tumor necrosis factor-alpha （TNF-<italic>α</italic>） in myocardial tissues. The expression levels of NF-<italic>κ</italic>B p65 and I<italic>κ</italic>B<italic>α</italic> were detected by immunohistochemistry. NF-<italic>κ</italic>B p65， I<italic>κ</italic>B<italic>α</italic>， TNF-<italic>α</italic>， and TLR4 mRNA expression levels were detected by real-time fluorescence-based quantitative polymerase chain reaction（Real-time PCR）. Result:The protein and mRNA levels of TLR4， NF-<italic>κ</italic>B p65， I<italic>κ</italic>B<italic>α</italic>， and TNF-<italic>α </italic>were higher in the model group than those in the normal group （<italic>P</italic><0.01）. TLR4， NF-<italic>κ</italic>B p65， I<italic>κ</italic>B<italic>α</italic>， and TNF-<italic>α</italic> protein and mRNA expression levels were reduced to varying degrees in the groups with drug intervention as compared with those in the model group （<italic>P</italic><0.01）. The inter-group comparison revealed that the co-treatment group showed more manifest reduction in protein and mRNA expression levels of TLR4， NF-<italic>κ</italic>B p65， I<italic>κ</italic>B<italic>α，</italic> and TNF-<italic>α </italic>than the phlegm-resolving group and the stasis-resolving group （<italic>P</italic><0.05<italic>，P</italic><0.01）. Conclusion:The co-treatment of phlegm and stasis can improve myocardial inflammation in DM rats， with superior effect to either the phlegm-resolving method or the stasis-resolving method. The underlying mechanism may be related to the inhibition of TLR4/NF-<italic>κ</italic>B/I<italic>κ</italic>B signaling pathway activation.

Method:A total of 97 patients admitted in our department from October 2017 to August 2019 were collected. The traditional Chinese medicine (TCM) syndromes were consistent with blood stasis and channel blockage, and diagnosed as VBD by magnetic resonance angiography (MRA). The patients were divided into experimental group (48 cases) and control group (49 cases). Control group was given basic therapy and placebo of TCM, while treatment group was given basic therapy and modified Tongqiao Huoxuetang for 30 days. The degree of relief of vertigo symptoms, vertigo symptom scale (VSS), activity balance confidence (ABC), transcranial doppler (TCD) bilateral vertebral artery and basilar artery blood flow velocity [systolic blood flow velocity (Vs), mean blood flow velocity (Vm), diastolic blood flow velocity (Vd)], mean blood flow differences between (MFV), pulsatility index, resistance index (RI), and wall shear force (WSS) were observed before and after treatment. Result:Compared with control group before treatment, the score of ABC scale in control group after treatment was markedly higher, while the score of VSS was significantly lower (P<0.05). However, there was no statistical significance in the score of vertigo symptom. Compared with treatment group before treatment, the symptom grade of vertigo degree and the score of VSS in treatment group after treatment were substantially lower, while the score of ABC scale was significantly higher (P<0.05). Compared with control group, the score of vertigo degree symptoms and VSS in treatment group were markedly lower, while the score of ABC scale was significantly higher (P<0.05). Compared with control group before treatment, Vm, MFV and WSS of bilateral vertebral artery in control group after treatment were substantially higher, while RI was significantly lower (P<0.05). However, there were no statistical significances in Vs, Vd and PI in control group before and after treatment. Compared with treatment group, Vs, Vd, Vm, MFV and WSS of bilateral vertebral artery in treatment group after treatment were markedly higher, while RI was significantly lower (P<0.05). However, there was no statistical significance in PI of experimental group before and after treatment. Compared with control group after treatment, Vs, Vd, Vm, MFV and WSS of bilateral vertebral artery in treatment group after treatment were substantially higher, while there was no statistical significance in PI and RI. Before and after treatment, there were similar changes in blood flow parameters of the basilar artery and bilateral vertebral artery. Conclusion:Modified Tongqiao Huoxuetang could improve the clinical symptoms of dizziness or vertigo in patients of VBD due to blood stasis and channel blockage, and the mechanism might be related to the improvement of post-circulation hemodynamics by Tongqiao Huoxuetang.

Impact of thoracic duct ligation on substance metabolism and surgical complications in patients with type-2 diabetes mellitus during esophagectomy / 中国胸心血管外科临床杂志

@#Objective    To investigate the impact of thoracic duct ligation (TDL) on metabolism and postoperative complications during esophagectomy in patients with type-2 diabetes mellitus (T2DM). Methods    We conducted a retrospective clinical data analysis of 230 esophageal carcinoma patients with T2DM who underwent esophagectomy in our hospital from January 2003 to December 2018. Patients were divided into a TDL+ group (n=112), including 78 males and 34 females aged 63.47±7.23 years, and a TDL– group (n=118), including 84 males and 34 females aged 64.38±7.57 years. We compared the blood glucose, liver function parameters and lipid metabolic parameters at different time points before and after surgery. In addition, we compared the postoperative major complications between the two groups. Propensity score-matched (PSM) was used to control the observed confounders. Results    Compared with the TDL–group, patients in TDL+ group had higher blood glucose level (P<0.05, except the fourth postoperative day). The total protein and albumin levels on the first and fourth postoperative days in the TDL+ group were lower than those in the TDL– group (P<0.05). The alanine transaminase (P=0.027) and aspartate transaminase (P=0.007) levels on the fourth postoperative day in the TDL+ group were higher than those in the TDL– group. More pulmonary complications (P=0.014) and anastomotic leaks (P=0.047) were found in the TDL+ group. Conclusion    Given that TDL may aggravate metabolic disorders, increase anastomotic leaks and the pulmonary complications, it is cautious to perform TDL, and prophylactic TDL should not be performed routinely for patients with T2DM.

Review of Zuoguiwan on Animal Models and Evaluation in Prevention and Treatment of Osteoporosis / 中国实验方剂学杂志

Zuoguiwan is a classic prescription for replenishing vital essence, tonifying kidney-Yin and nourishing the bone marrow. Zuoguiwan is one of the effective prescriptions for the prevention and treatment of osteoporosis (OP), which reflects the thought of Reinforcing Yang from Yin. The OP animal model simulates the pathological state and pathogenesis of OP in human, which is an important means to research the pathogenesis of OP and verify the effect of drugs. In this paper, two kinds of animal models and characteristics of Zuoguiwan in the prevention and treatment of osteoporosis were discussed in details. They are the primary osteoporosis animal models, including ovariectomized animal models and spontaneous elderly osteoporosis animal models, and the secondary osteoporosis models, including glucocorticoid-induced animal models, cyclophosphamide-induced animal models and subtotal nephrectomy animal models. The evaluation methods of Zuoguiwan in preventing and treating OP, including bone absorption markers and bone formation markers analyzed by enzyme-linked immunosorbent assay (ELISA), bone mineral density detected with dual-energy X-ray, the number of trabeculae, trabecular segregation, trabecular thickness, bone volume/tissue volume ratio and bone surface/volume ratio analyzed using micro-CT, bone pathological morphology observed by hematoxylin-eosin staining, bone biomechanical properties, such as the maximum load force based on biomechanical test. In order to provide scientific reference for the basic and clinical research of Zuoguiwan, the OP animal models and the pharmacodynamic effect of Zuoguiwan are evaluated comprehensively with five different and objective evaluation methods. However, the animal model of OP needs to be further optimized to highlight the pathogenesis and syndrome characteristics of Zuoguiwan in the treatment of OP.

Objective: To observe the mRNA levels of Orexin and its receptors in the hypothalamus of ovariectomized osteoporosis rats, in order to explore the pathogenesis of postmenopausal osteoporosis(PMOP) and the mechanism Zuoguiwan. Method: An osteoporosis model induced by ovariectomy was established in rats. Totally 32 female Sprague-Dawley (SD) rats were randomly divided into sham-operated group, ovariectomized model group, 17β-estradiol treated positive group, and Zuoguiwan group, with 8 rates in each group. After 12 weeks of intragastric administration, the bone mineral density (BMD) and trabecular microstructural changes of femur were detected by micro-CT (μ-CT), and the morphological changes of bone tissue were observed by hematoxylin-eosin staining (HE) staining. The markers of bone turnover in serum osteocalcin (OCN), N-terminal propeptide of type Ⅰ procollagen (PINP), tartrate-resistant acid phosphatase (TRAP) were measured using enzyme-linked immunosorbent assay (ELISA). The mRNA expressions of orexin, orexin receptor 1 (OX1R) and orexin receptor 2 (OX2R) were measured by Real-time PCR. Result: Compared with sham-operated group, the μ-CT showed that BMD, bone volume fraction(BV/TV), trabecular thickness(Tb. Th)and trabecular number(Tb. N)in ovariectomized model group were significantly decreased (PPN-terminal propeptide of type Ⅰ procollagen (PINP) levels decreased, whereas tartrate-resistant acid phosphatase (TRAP) content increased (PPPPPPPPPPConclusion: Decreased mRNA levels of Orexin and its receptors in the hypothalamus may be one of the mechanisms of PMOP. Zuoguiwan may correct the imbalance of bone metabolism, improve the trabecular microstructure and improve bone by up-regulating the mRNA expressions of Orexin and its receptors in the hypothalamus, density, so as to show a therapeutic effect on PMOP.

Effect of Zuoguiwan in Improving BMD and Trabecular Bone Microarchitecture in Ovariectomy-induced Osteoporosis Rats by Regulating RANKL/OPG Pathway Mediated by β2AR / 中国实验方剂学杂志

Objective: To investigate the mechanism of Zuoguiwan in treating ovariectomy-induced osteoporosis rats by receptor activator of nuclear factor kappa-B ligand (RANKL)/osteoprotegerin (OPG) signaling pathway mediated by β2-adrenergic receptor (β2AR). Method: Forty Sprague-Dawley female rats were randomly divided into Sham-operated group (Sham) and four ovariectomized (OVX) subgroups. Rats in Sham and OVX groups were treated with 17β-estradiol (50 μg·kg-1·d-1), and low and high-dose ZGW (2.3,4.6 g·kg-1 lyophilized powder) for 3 months, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to measure the serum markers of bone turnover. Micro-CT was used to evaluate and measure trabecular bone microarchitecture and bone mineral density (BMD) of the right distal femur. Western blot analysis and Real-time PCR were used to measure mRNA and protein expressions of β2AR, OPG and RANKL. Result: After 12 weeks of treatment with Zuoguiwan, the level of serum β-cross-linked c-telopeptide of type Ι collagen (β-CTX) (PPPβ2AR in the hypothalamus (PPConclusion: The mechanism of Zuoguiwan in alleviating BMD and trabecular bone microarchitecture in ovariectomy-induced osteoporosis rats might be related to the regulation of RANKL/OPG Pathway mediated by β2AR.
