Panax notoginseng is the dried root and rhizome of Panax notoginseng(Burk.)F.H.Chen,a perennial erect herb of the genus Ginseng of the family Wujiaceae.As a traditional Chinese medicine in our country,Panax notoginseng has a good tonic effect,and the Dictionary of Traditional Chinese Medicines has the words that Panax notoginseng is used to tonify the blood,remove the blood stasis and damage,and stop epistaxis.It can also be used to pass the blood and tonify the blood with the best efficacy,and it is the most precious one of the prescription med-icines.Eaten raw,it removes blood stasis and generates new blood,subdues swelling and stabilizes pain,stops bleeding with-out leaving stasis,and promotes blood circulation without hurting the new blood;taken cooked,it can be used to replenish and strengthen the body.Notoginsenoside R1 is a characteristic com-pound in the total saponin of Panax ginseng.In recent years,China's aging has been increasing,and the incidence of neuro-logical disorders has been increasing year by year.Meanwhile,reports on notoginsenoside R1 in the treatment of neurological disorders are increasing,and its neuroprotective effects have been exerted with precise efficacy.The purpose of this paper is to review the treatment of neurological diseases and the mecha-nism of action of notoginsenoside R1,so as to provide a certain theoretical basis for clinical use and new drug development.

Human brain banks use a standardized protocol to collect,process and store post-mortem human brains and related tissues,along with relevant clinical information,and to provide the tissue samples and data as a resource to foster neuroscience research according to a standardized operating protocols(SOP).Human brain bank serves as the foundation for neuroscience research and the diagnosis of neurological disorders,highlighting the crucial rule of ensuring the consistency of standardized quality for brain tissue samples.The first version of SOP in 2017 was published by the China Human Brain Bank Consortium.As members increases from different regions in China,a revised SOP was drafted by experts from the China Human Brain Bank Consortium to meet the growing demands for neuroscience research.The revised SOP places a strong emphasis on ethical standards,incorporates neuropathological evaluation of brain regions,and provides clarity on spinal cord sampling and pathological assessment.Notable enhancements in this updated version of the SOP include reinforced ethical guidelines,inclusion of matching controls in recruitment,and expansion of brain regions to be sampled for neuropathological evaluation.

Aim To investigate the effeet of Eehinaeo- side ( ECH ) regulating the expression of prohibitin (PHB) on MPP+ -induced apoptosis of SH-SY5Y eells and the underlying mechanism.Methods SH-SY5Y eells were seleeted and divided into control group, MPP+ group, MPP+ + ECH group, NC + MPP + group, NC + MPP+ + ECH group, PHB-RNAi + MPP + + ECH group.Cell survival rate was determined by CCK-8 assay.Cell morphology was observed using an inverted phase contrast mieroscope; the apoptotie eells were observed by Hoechst33342 fluorescence staining, whereas apoptotie rate, reactive oxygen speeies eon- tent, and mitochondrial membrane potential were ana¬lyzed by flow eytometry.The relative protein expres¬sions of PHB, Akt, p-Akt, Bel-2, Bax, and cleaved- easpase3 were determined by Western blot.Results Compared with eontrol group, the eell survival rate of MPP+ group signifieantly deereased.The growth state of the eells beeame significantly worse.Intracellular ROS content inereased, mitoehondrial membrane po tential decreased, apoptosis-related protein expression increased and the apoptotic rate increased.Compared with MPP+ group, MPP+ + ECH group significantly increased cell viability.The growth status of cells was significantly improved.Intracellular ROS content de¬creased, mitochondrial membrane potential increased, apoptosis-related protein expression decreased, and the apoptotic rate decreased significantly.The expression levels of PHB and p-Akt significantly increased.Com¬pared with NC + MPP+ + ECH group, p-Akt level de¬creased and the cell apoptotic rate increased in PHB- RNAi +MPP+ + ECH group.Conclusions Echino- side can reduce MPP + - induced apoptosis of SH-SY5Y cells, which may be realized by upregulating PHB ex¬pression and phosphorylation of Akt to protect mito¬chondrial function.

With the development of social economy and improvement of people's health condition， life expectancy continues to extend and people are more concerned about the quality of life. Nowadays people's attention has shifted from living longer lives to living healthier lives. Life expectancy can only reflect the length of life， but not the health condition and quality of life. Meanwhile， healthy life expectancy contains death and disability information， which comprehensively reflects the length and quality of life and evaluates the health status of the population comprehensively. Through literature search and review， the article summarized the research on healthy life expectancy in recent years， including the concept proposal， index development， calculation， and application progress of health life expectancy. The research methods of healthy life expectancy are summarized in order to provide academic reference for further research.

Objective: To predict B cell and T cell epitopes of 22-kDa, 47-kDa, 56-kDa and 58-kDa proteins. Methods: The sequences of 22-kDa, 47-kDa, 56-kDa and 58-kDa proteins which were derived from Orientia tsutsugamushi were analyzed by SOPMA, DNAstar, Bcepred, ABCpred, NetMHC, NetMHC II and IEDB. The 58-kDa tertiary structure model was built by MODELLER9.17. Results: The 22-kDa B-cell epitopes were located at positions 194-200, 20-26 and 143-154, whereas the T-cell epitopes were located at positions 154-174, 95-107, 17-25 and 57-65. The 47-kDa protein B-cell epitopes were at positions 413-434, 150-161 and 283-322, whereas the T-cell epitopes were located at positions 129-147, 259-267, 412-420 and 80-88. The 56-kDa protein B-cell epitopes were at positions 167-173, 410-419 and 101-108, whereas the T-cell epitopes were located at positions 88-104, 429-439, 232-240 and 194-202. The 58-kDa protein B-cell epitopes were at positions 312-317, 540-548 and 35-55, whereas the T-cell epitopes were located at positions 415-434, 66-84 and 214-230. Conclusions: We identified candidate epitopes of 22-kDa, 47-kDa, 56-kDa and 58-kDa proteins from Orientia tsutsugamushi. In the case of 58-kDa, the dominant antigen is displayed on tertiary structure by homology modeling. Our findings will help target additional recombinant antigens with strong specificity, high sensitivity, and stable expression and will aid in their isolation and purification.

BackgroundHand injuries are very common in sports, such as skiing and ball sports. One of the major reasons causing hand and finger deformity is due to ligament and tendon injury. The aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging (MRI) can demonstrate the complex anatomy of the fingers and thumb, especially the tendons and ligaments, and provide the accurate diagnosis of clinically important fingers and thumbs deformity due to ligamentous and tendinous injuries during sport activities.

MethodsSixteen fresh un-embalmed cadaveric hands were harvested from eight cadavers. A total of 20 healthy volunteers' hands and 44 patients with fingers or thumb deformity due to sports-related injuries were included in this study. All subjects had MR examination with T1-weighted images and proton density-weighted imaging with fat suppression (PD FS) in axial, coronal, and sagittal plane, respectively. Subsequently, all 16 cadaveric hands were sliced into 2-mm thick slab with a band saw (six in coronal plane, six in sagittal plane, and four in axial plane). The correlation of anatomic sections and the MRI characteristics of tendons of fingers and the ulnar collateral ligament (UCL) at the metacarpal phalangeal joint (MCPJ) of thumb between 20 healthy volunteers and 44 patients (confirmed by surgery) were analyzed.

ResultsThe normal ligaments and tendons in 16 cadaveric hands and 20 volunteers' hands showed uniform low-signal intensity on all the sequences of the MRI. Among 44 patients with tendinous and ligamentous injuries in the fingers or thumb, 12 cases with UCL injury at MCPJ of the thumb (Stener lesion = 8 and non-Stener lesion = 4), 6 cases with the central slip injury, 12 cases with terminal tendon injury, and 14 cases with flexor digitorum profundus injury. The ligaments and tendons disruption manifested as increased signal intensity and poor definition, discontinuity, and heterogeneous signal intensity of the involved ligaments and tendons.

ConclusionsSports injury-related fingers and thumb deformity are relatively common. MRI is an accurate method for evaluation of the anatomy and pathologic conditions of the fingers and thumb. It is a useful tool for accurate diagnosis of the sports-related ligaments and tendons injuries in hand.

OBJECTIVETo exam the effect and safety of conventional acupuncture (CA) on cardiac arrhythmia.

METHODSNine medical databases were searched until February 2016 for randomized controlled trials. Heterogeneity was measured by Cochran Q test. Meta-analysis was conducted if I was less than 85% and the characteristics of included trials were similar.

RESULTSNine qualified studies involving 638 patients were included. Only 1 study had definitely low risk of bias, while 7 trials were rated as unclear and 1 as high. Meta-analysis of CA alone did not have a significant benefit on response rate compared to amiodarone in patients with atrial fibrillation (Af) and atrial flutter (AF) [relative risk (RR): 1.09; 95% confidence interval (CI): 0.79-1.49; P=0.61; I=61%, P=0.11]. However, 1 study with higher methodological quality detected a lower recurrence rate of Af in CA alone as compared with sham acupuncture plus no treatment, and benefits on ventricular rate and time of conversion to normal sinus rhythm were found in CA alone group by 1 study, as well as the response rate in CA plus deslanoside group by another study. Meta-analysis of CA plus anti-arrhythmia drug (AAD) was associated with a significant benefit on the response rate when compared with AAD alone in ventricular premature beat (VPB) patients (RR, 1.19, 95% CI: 1.05-1.34; P=0.005; I=13%, P=0.32), and an improvement in quality-of-life score (QOLS) of VPB also showed in 1 individual study. Besides, a lower heart rate was detected in the CA alone group by 1 individual study when compared with no treatment in sinus tachycardia patients (MD-21.84 [-27.21,-16.47]) and lower adverse events of CA alone were reported than amiodarone.

CONCLUSIONSCA may be a useful and safe alternative or additive approach to AADs for cardiac arrhythmia, especially in VPB and Af patients, which mainly based on a pooled estimate and result from 1 study with higher methodological quality. However, we could not reach a robust conclusion due to low quality of overall evidence.

Alzheimer's disease (AD) is a type of common neurodegenerative disease. The main clinical symptom of the disease is progressive cognitive dysfunction, which has no effective therapy yet. With the in-depth immunology study in the central nervous system, studies in different fields such as preclinical phase, genetics and bioinformatics have shown that immune dysfunction contribute to the pathogenesis of AD, including the beginning, maintenance and deterioration stage in AD. China has a wealth of natural medicine resources and clinical experiences. A large number of natural drugs and effective components both can regulate the immune function and ameliorate the symptoms in AD. This review summarizes the researches of ameliorating the symptoms in AD through immunization regulation in recent years with an aim to provide new ideas and clues in the study of new anti-AD drugs using natural medicines.

The main ingredient of extractable petroleum ether of Polyrhachis vicina Roger (EPPR) is octadecene unsaturated fatty acids. Mounting evidence supports that N-3 polyunsaturated fatty acids can attenuate neuroinflammation, reduce oxidative stress, then protect neurons. In order to explore the effect of EPPR on the inflammatory response of depressed rats, the model of depression was established by chronic unpredictable mild stress (CUMS). Sucrose preference test, forced swimming test were employed to investigate the anti-depressive effect of EPPR in rat. The activation of glial cells and astrocytes in the prefrontal cortex of depressed rats was observed by immunofluorescence. The levels of inflammatory factors were measured by Quantitative Real-time PCR. NF-κB was detected by immunoblotting. EPPR could significantly improve the depressive behavior of rats, decrease NF-κB translocation to the compartment of nucleus, down-regulate the pro-inflammatory cytokines IL-1β, TNF-α and indoleamine 2,3-dioxygenase (IDO) gene expression levels, inhibit the activation of microglia and astrocytes in depressed rats. These results suggest that EPPR could notably ameliorate inflammation induced by chronic stress, and the protective effect might be linked to the regulation of NF-κB p65.
