Research progress on traditional Chinese medicine in treatment of neurodegenerative diseases by delaying neurovascular unit aging / 中国中药杂志

Neurodegenerative diseases are a collective term for a large group of diseases caused by degenerative changes in nerve cells. Aging is the main risk factor for neurodegenerative diseases. The neurovascular unit(NVU) is the smallest functional unit of the brain, which regulates brain blood flow and maintains brain homeostasis. Accelerated aging of NVU cells directly impairs NVU function and leads to the occurrence of various neurodegenerative diseases. The intrinsic mechanisms of NVU cell aging are complex and involve oxidative stress damage, loss of protein homeostasis, DNA damage, mitochondrial dysfunction, immune inflammatory response, and impaired cellular autophagy. In recent years, studies have found that traditional Chinese medicine(TCM) can inhibit NVU aging through multiple pathways and targets, exerting a brain-protective effect. Therefore, this article aimed to provide a theoretical basis for further research on TCM inhibition of NVU cell aging and references for new drug development and clinical applications by reviewing its mechanisms of anti-aging, such as regulating relevant proteins, improving mitochondrial dysfunction, reducing DNA damage, lowering inflammatory response, antioxidant stress, and modulating cellular autophagy.

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.

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.

Co-Treatment of Phlegm and Stasis Improves Myocardial Inflammation in Rats with Diabetes Mellitus via TLR4/NF-κB/IκB Pathway / 中国实验方剂学杂志

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.

β-caryophyllene alleviates cerebral ischemia/ reperfusion injury in mice by activating autophagy / 中国中药杂志

Cerebral ischemia-reperfusion(I/R) injury is an important cause of acute ischemic stroke. Timely elimination of damaged proteins and organelles by regulating autophagy during cerebral ischemia-reperfusion plays an important role in relieving brain damage. In order to investigate whether β-caryophyllene(BCP) could protect neurons from cerebral I/R injury by regulating auto-phagy, C57 BL/6 J male mice were randomly divided into sham operation group, model group, and drug-administered group. After intra-gastric administration was given for 5 days, the middle cerebral artery occlusion(MCAO) model was established by suture method. Twenty four hours after surgery, the infarct volume and neurological function were assessed; the pathological changes of cortical tissue were observed by HE staining; Western blot was used to detect the expression of autophagy-related proteins beclin1, p62, LC3 B and apoptosis-related protein Bcl-2; immunofluorescence was used to observe the expression of LC3 B in the ischemic cortex. The autophagy of cortical tissue in the ischemic area was observed by transmission electron microscopy. The experimental results showed that as compared with the model group, the BCP pretreatment significantly reduced the neurological deficit, decreased the percentage of cerebral infarction volume, reduced the death of brain tissue cells in the ischemic area, up-regulated the expression of beclin1, LC3 B and Bcl-2 protein, down-regulated p62 protein expression, and significantly increased the number of autophagosomes in the cortical tissue of the ischemic area. It was finally determined that BCP could protect neurons from cerebral ischemia-reperfusion injury by activating autophagy.

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.

Objective:To observe the effect of modified Tongqiao Huoxuetang on circulating blood flow and wall shear stress of vertebrobasilar dolichoectasia (VBD) due to blood stasis and channel blockage. 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.

According to the guidelines on the diagnosis and treatment of COVID-19 (6th trial edition), the latest relative literature at home and abroad, the features of the COVID-19, recommendations for the COVID-19 prevention and control issued by the National Health Commission of China, and management experience of diagnosis and treatment in the related disciplines, we put forward recommendations for the medical practices of burn treatment during the outbreak of the COVID-19 in outpatient and emergency treatment, inpatient treatment, operation and ward management, etc. We hope these recommendations could benefit the professionals of the same occupation as us and related hospital managers, improve the treatment of burn during the outbreak of the COVID-19, and avoid or reduce the risk of infection of medical staff .

Analysis of anti-fatigue mechanism and potential targets of ginseng / 中国中药杂志

Ginseng has effects in reinforcing vital energy,invigorating health effectively and relieving fatigue symptoms,and ginsenoside( GS) is the main component of its anti-fatigue effect. Totally 17 active components and 92 drug targets of ginseng compounds were screened from Traditional Chinese Medicine Systems Pharmacology; and 78 intersecting genes of diseases and drug targets were obtained based on R Language Technology. The protein-protein interaction( PPI) network was constructed by STRING 11. 0 software,and Matthews Correlation Coefficient( MCC) algorithm was used to screen core target genes. Gene ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were used to analyze the major genes and their roles in regulatory networks. The results indicated that ginseng could regulate the core target genes,including AKT serine/threonine kinase( AKT1),interleukin-1β,Toll-like receptor binding molecule 1( ICAM1),mitogen-activated protein kinase 8( MAPK8),AP-1 transcription factor subunit( JUN),transducer and activator of transcription 1( STAT1) and prostaglandin peroxidase synthase 2( PTGS2). It could participate in the functions of cytokine receptor binding,cell adhesion molecule binding and tumor necrosis factor receptor superfamily binding,and also regulate the signal pathways of tumor necrosis factor,interleukin 17 and c-type lectin receptor,so as to exert an anti-fatigue effect. Based on the results of network analysis,32 four-week-old male SPFACR mice were randomly divided into control group,low-dose ginsenoside group,middle-dose ginsenoside group and high-dose ginsenoside group. The corresponding drugs were administrated for 3 weeks. The results showed that GS could significantly up-regulate the expressions of STAT1 and AKT1( P<0. 01,P<0. 05),and downregulate the expressions of PTGS2 and JUN( P<0. 01). However,there was no significant effect on MAPK8,IL-1β and ICAM1. Ginseng's anti-fatigue regulation network was constructed through network pharmacology,and the results were verified by experiments,in order to reveal the anti-fatigue mechanism of ginseng and provide scientific basis for its clinical application.

Application of case-guided problem-based learning model in clinical practice of burn surgery / 中华医学教育探索杂志

The problem-based learning ( PBL ) model has been widely used in higher medical education in China and foreign countries and has been constantly improved. The case-guided PBL model is gradually used in the clinical practice of burn surgery by the establishment of a database of typical cases. This student-centered method can fully mobilize subjective initiative of students and help them to form correct clinical thinking methods and the ability to analyze and solve problems, so as to improve the quality of clinical teaching of burn surgery.

Surgical patient safety: experience and inspiration from Singapore public hospitals / 中华医院管理杂志

Patient safety is an integral part of a successful health care system. It addresses and reduces risks and incidents that may negatively impact patients through implementation of improvement projects in various aspects. We discussed proven experiences in surgical patient safety management in Singapore public hospitals, with focus on hospital leadership and management, patient consultation and adoption of clinical protocols. Hierarchy and teamwork were used together with modern information technologies to reduce human errors. During patient consultation, standard informed consent acquisition process was advocated with full respect for patient′s right of decision making. Limited medical resources and manpower were assigned by careful triage and meticulous clinical protocols, which can ensure quality of surgical care. These experiences are inspirational for improving surgical patient safety in China.
