Penerapan Metode Bayes untuk Mendiagnosa Penyakit Saraf Kejepit

A pinched nerve is a condition where certain nerves are compressed by tissues around the body, such as bones, cartilage and muscles. This causes the nerve to become damaged with symptoms of severe pain, tingling, and numbness during activity. Nerve pain can spread throughout the body. For example, patients with radiculopathy type spinal cord disease make the patient numb, and the nerve pain can spread to the feet and hands. Sylvani General Hospital also provides expert doctors who treat various diseases, including pinched nerve disease suffered by patients. However, there are several problems that often occur to patients when going for direct consultation due to time constraints, long queues, long waits, long distances to the hospital, and lack of costs. Because agencies need to have a system that can manage existing symptom data on pinched nerve disease and make it an online expert substitute information by utilizing technological developments to get maximum diagnostic results, and patients can find out the initial symptoms of one of them numbness, leg pain, arm pain, back pain, muscle weakness in the type of pinched nerve disease, namely radiculopathy, carpal tunnel syndrome, pinched nerves in the waist, piriformis syndrome, radial tunnel syndrome and treatment first by consulting through a system that has been created using the Bayes method. From the calculation process using the Bayes method above, it is known that the diagnosis of pinched nerve disease is diagnosed with nerve root syndrome (Radiculopathy) (P01) with a percentage of 72.55%.

Current Status of Yam Diseases and Advances of Their Control Strategies

Yam (Dioscorea spp.) is an important tuber crop consumed globally. However, stable yam production faces challenges from a variety of diseases caused by fungi, nematodes, viruses, and bacteria. Prominent diseases such as anthracnose, leaf spot, yam wilt, dry rot, and crazy root syndrome, currently pose serious threats to yam yields. These diseases not only result in quality degradation but also cause great economic losses. This review summarizes the damages, symptoms, causal agents, and epidemic factors of major yam diseases. It also outlines a comprehensive disease control strategy that includes the use of resistant varieties, proper crop rotation, sanitation measures, and the application of agrochemicals and biocontrol agents. Additionally, this review addresses future perspectives on risk factors and knowledge gaps, aiming to serve as a reference for in-depth research into advanced disease monitoring and control technologies for yams.

6. Persistent spinal pain syndrome type 2.

Persistent Spinal Pain Syndrome (PSPS) refers to chronic axial pain and/or extremity pain. Two subtypes have been defined: PSPS-type 1 is chronic pain without previous spinal surgery and PSPS-type 2 is chronic pain, persisting after spine surgery, and is formerly known as Failed Back Surgery Syndrome (FBSS) or post-laminectomy syndrome. The etiology of PSPS-type 2 can be gleaned using elements from the patient history, physical examination, and additional medical imaging. Origins of persistent pain following spinal surgery may be categorized into an inappropriate procedure (eg a lumbar fusion at an incorrect level or for sacroiliac joint [SIJ] pain); technical failure (eg operation at non-affected levels, retained disk fragment, pseudoarthrosis), biomechanical sequelae of surgery (eg adjacent segment disease or SIJ pain after a fusion to the sacrum, muscle wasting, spinal instability); and complications (eg battered root syndrome, excessive epidural fibrosis, and arachnoiditis), or undetermined. The literature on the diagnosis and treatment of PSPS-type 2 was retrieved and summarized. There is low-quality evidence for the efficacy of conservative treatments including exercise, rehabilitation, manipulation, and behavioral therapy, and very limited evidence for the pharmacological treatment of PSPS-type 2. Interventional treatments such as pulsed radiofrequency (PRF) of the dorsal root ganglia, epidural adhesiolysis, and spinal endoscopy (epiduroscopy) might be beneficial in patients with PSPS-type 2. Spinal cord stimulation (SCS) has been shown to be an effective treatment for chronic, intractable neuropathic limb pain, and possibly well-selected candidates with axial pain. The diagnosis of PSPS-type 2 is based on patient history, clinical examination, and medical imaging. Low-quality evidence exists for conservative interventions. Pulsed radiofrequency, adhesiolysis and SCS have a higher level of evidence with a high safety margin and should be considered as interventional treatment options when conservative treatment fails.

From acquisitive to conservative: The ontogenetic trajectory of root syndrome of annual and perennial co-generic species

Perennials has been proposed as new crops because their root syndrome offers more ecosystem services and a better use of resources than the annual one. Objective: To compare the ontogenetic trajectory of root syndromes of annual (P. gracilis and P. angustifolia) and perennial (P. pinetorum and P. mendocina) species of Physaria (Brassicaceae) and their root trait relationships. Results and ConclusionRoots became conservative as plants grew, independently of the life cycle of the species. However, perennials invested initially more resources in increasing storage capacity (bigger and thicker roots) while annuals favored increasing the exploration capacity (higher SRL). During first anthesis we found tradeoffs between acquisitive and conservative traits, as expected according to the Root Economic Spectrum (RES), but after the first year, those tradeoffs disappeared and perennials were able to combine a thick and deep taproot and high investment in C reserves with some well-developed acquisitive traits such as higher SRL and total length. This suggest that root traits should be selected during the second year, when no tradeoff exist. Differences between annuals and perennials in most structural taproot traits remained constant along the ontogenetic trajectory, thus the relative position of species in the RES did not change over time. We found a gradient of root strategies supported by the RES theory: from acquisitive in the annual P. gracilis (high SRL, STD and total length) to conservative in the perennial P. mendocina (high root biomass, root diameter, tissue density and storage) with intermediate strategies in P. angustifolia and P. pinetorum.

Transcriptome analysis provides insights into the cell wall and aluminum toxicity related to rusty root syndrome of Panax ginseng.

Rusty root syndrome is a common and serious disease in the process of Panax ginseng cultivation. This disease greatly decreases the production and quality of P. ginseng and causes a severe threat to the healthy development of the ginseng industry. However, its pathogenic mechanism remains unclear. In this study, Illumina high-throughput sequencing (RNA-seq) technology was used for comparative transcriptome analysis of healthy and rusty root-affected ginseng. The roots of rusty ginseng showed 672 upregulated genes and 526 downregulated genes compared with the healthy ginseng roots. There were significant differences in the expression of genes involved in the biosynthesis of secondary metabolites, plant hormone signal transduction, and plant-pathogen interaction. Further analysis showed that the cell wall synthesis and modification of ginseng has a strong response to rusty root syndrome. Furthermore, the rusty ginseng increased aluminum tolerance by inhibiting Al entering cells through external chelating Al and cell wall-binding Al. The present study establishes a molecular model of the ginseng response to rusty roots. Our findings provide new insights into the occurrence of rusty root syndrome, which will reveal the underlying molecular mechanisms of ginseng response to this disease.

Late answers in the electroneuromyography of patients with degenerative-dystrophic spine disorders

We carried out electroneuromyography of 78 patients with degenerative-dystrophic cervical and lumbar spine disorders, which were treated at the neurosurgical department of the Irkutsk Scientific Centre of Surgery and Traumatology. The results of the study of late ENMG phenomena such as H-reflex, F-waves and A-reflex were obtained at different stages of the disease using “Neuromyan” neuromyoanalyzer. The predictable changes in late answers at different stages of the process were determined. For example, in patients with radiculopathy, the degree of neurological deficiency was minimal, and in patients with a combination of nerve root syndrome and stenotic changes, the neurological deficiency had the character of a pronounced bilateral pathology. The severity of changes in neurophysiological indicators depends on the degree of spinal stenosis. Determination of N-reflex and F-wave parameters allows us to identify subclinical forms of loss both at the level of peripheral nerves and of spinal cord segments, and the appearance of axon reflex is an evidence of a demyelinizing pathology and chronic process.

Phytophthora pseudocryptogea, P. nicotianae and P. multivora Associated to Cycas revoluta: First Report Worldwide.

A dieback was observed on three-year-old pot-grown plants of Cycas revoluta in Sicily (Italy). Symptoms, including stunting, yellowing and blight of the leaf crown, root rot and internal browning and decay of the basal stem, closely resembled the Phytophthora root and crown rot syndrome, common in other ornamentals. Isolations from rotten stem and roots, using a selective medium, and from rhizosphere soil of symptomatic plants, using leaf baiting, yielded three Phytophthora species, P. multivora, P. nicotianae and P. pseudocryptogea, were obtained. Isolates were identified by both morphological characters and DNA barcoding analysis, using three gene regions: ITS, β-tub and COI. Phytophthora pseudocryptogea was the sole species isolated directly from the stem and roots. The pathogenicity of the isolates of the three Phytophthora species was tested on one-year-old potted plants of C. revoluta, using both stem inoculation by wounding, and root inoculation through infested soil. Phytophthora pseudocryptogea was the most virulent and, like P. nicotianae, reproduced all the symptoms of natural infections, while P. multivora was the least virulent and induced solely very mild symptoms. Phytophthora pseudocryptogea was identified as the causal agent of the decline of C. revoluta, as it was re-isolated from both the roots and stems of artificially infected symptomatic plants, thus fulfilling Koch's postulates.

Root structure syndromes of four families of monocots in the Middle Urals

The present article tests the following general assumption: plant taxa with different specializations towards mycorrhizal interactions should have different root syndromes. Roots of 61 species common in boreal zone were studied: 16 species of Poaceae, 24 species of Cyperaceae, 14 species of Orchidaceae, and 7 species of Iridaceae. Using a fixed material of 5 individuals of each species, the following was determined: number of orders of branching roots; transverse dimensions of root, stele and cortex; number of primary xylem vessels and exodermis layers; length of root hairs; abundance of mycorrhiza. Species of each family had well-defined syndromes. Roots of Orchidaceae and Iridaceae were thick with a large stele and developed exodermis. Orchidaceae had no branching roots and had long root hairs. In Iridaceae, roots were branched, and root hairs were short. Roots of Poaceae and Cyperaceae were thin with a relatively thin stele. Root hairs were short in Poaceae and long in Cyperaceae. Our finding that root syndromes of four families of monocots differed is a new and unexpected discovery. The high specificity of root syndromes in Cyperaceae, Iridaceae, Poaceae, and Orchidaceae indicates that species of these families use different strategies to obtain water and soil nutrients.

Effectiveness of caudal block in patients with spinal stenosis accompanied by redundant nerve root syndrome

Redundant nerve root syndrome (RNRS) is characterized by tortuous, elongated, and enlarged nerve roots in patients with lumbar spinal stenosis. This study was performed to evaluate the effects of caudal block in patients with RNRS and assess factors associated with RNRS. Patients with lumbar spinal stenosis who underwent caudal block were retrospectively analyzed. A comparative analysis of pain reduction was conducted between patients with RNRS (Group R) and those without RNRS (Group C). Generalized estimating equation analysis was used to identify factors related to the treatment response. RNRS-associated factors were analyzed using logistic regression analysis. In total, 54 patients were enrolled (Group R, n = 22; Group C, n = 32). Group R had older patients than Group C. The caudal block showed less pain reduction in Group R than in Group C, but the difference was not statistically significant. Generalized estimating equation analysis showed that RNRS was the factor significantly associated with the treatment response. The dural sac anteroposterior diameter and left ligamentum flavum thickness were associated with RNRS in the logistic regression analysis. Caudal block tended to be less effective in patients with than without RNRS, but the difference was not statistically significant.

Anatomical mining method of cervical nerve root syndrome under visual sensing technology

INTRODUCTION: The gray resolution of anatomical image of cervical nerve root syndrome is low, that can not be mined accurately. OBJECTIVES: Aiming at the defect of low gray resolution of anatomical images, an image mining method using visual perception technology was studied. METHODS: According to the visual perception technology, the internal parameter matrix and external parameter matrix of binocular visual camera were determined by coordinate transformation, and the anatomical images of cervical nerve root syndrome were collected. The collected images are smoothed and enhanced by nonlinear smoothing algorithm and multi-scale nonlinear contrast enhancement method. The directional binary simple descriptor method is selected to extract the features of the enhanced image; Using K-means clustering algorithm, the anatomical image mining of cervical nerve root syndrome is completed by obtaining the initial clustering center and image mining. RESULTS: Experimental results show that the information entropy of the images mined by the proposed method is higher than 5, the average gradient is greater than 7, the edge information retention is greater than 0.7, the peak signal-to-noise ratio is higher than 30 dB, and the similarity of the same category of images is greater than 0.9. CONCLUSIONS: This method can effectively mine the anatomical images of cervical nerve root syndrome and provide an important basis for the diagnosis and treatment of cervical nerve root syndrome.

Сomparative effectiveness of various methods of epidural administration of glucocorticosteroids in treating root pain syndromes

This review aimed to compare the effectiveness of different methods of epidural glucocorticosteroid (GCS) use in the treatment of root syndrome pain according to literature over the past 20 years. A literary search was conducted in the databases of PubMed, MEDLINE, EMBASE, Cochrane Library, and Google Scholar, as well as a manual search of bibliographies of famous primary and review articles and abstracts of scientific meetings between 2000 and 2020. During the search, 637 studies were identified, of which 615 were excluded, as they did not correspond to the topic of the article. The remaining 22 studies were included in this review.
 Scientific papers describe three ways to deliver glucocorticosteroids, namely, epiduralinterlaminar injection, transforaminal injection, sacralepidural injection.
 For sciatica, 5 out of 8 comparative randomized controlled trials found the transforaminal route of administration to be superior to the sacroepidural or interlaminar route of administration. In a number of studies, the sacroepidural route of administration was comparable in efficiency with transfor-real with low herniated discs.
 In cases of cervicobrachialgia, the transforaminal route of administration is recognized by most authors as unsafe, with risks of accidental intravascular injection. In this regard, at the cervical level, interlaminar access is considered preferable. In addition, the differences between the epidural use of water-soluble and dispersed (not approved for use in the Russian Federation) glucocorticosteroids are described.
 The review describes the techniques of various approaches to the epidural space with their advantages and disadvantages.
 Different methods require different material equipment of clinics. Sacral access, with relatively high efficiency, allows for blind use, in contrast to transforaminal access at the lumbar level and interlaminar access at the cervical level, which require X-ray navigation.

Integrative analysis of multiple metabolomes and transcriptome revealed color expression mechanism in red skin root syndrome of Panax ginseng

Red skin root syndrome causes reduction of both production and quality of Panax ginseng (ginseng). However, its development process and key metabolites are still unknown. Multiple metabolomes including non-targeted metabolome, and anthocyanins-targeted and carotenoids-targeted metabolomes were performed on field grown red skin and healthy ginseng. The detected metabolites were analyzed in combination with previous transcriptome results. The total metabolite profiles revealed that primary metabolites especially citrate was decreased, but secondary metabolites mainly involved in phenylpropanoid pathway were increased in red skin ginseng compared to those in healthy ginseng. Targeted metabolome found that each gram of fresh red skin ginseng sample contained 8 μg β-carotene, 0.56 μg α-carotene, 0.017 μg rutin, 0.248 μg chalcone, and some anthocyanins including 0.023 μg cyanidin and 0.037 μg quercetin 3-O-glucoside, albeit in low concentrations but higher than those in healthy ginseng. Furthermore, integrative metabolome and transcriptome analysis revealed that changes of metabolites related to anthocyanins synthesis were correlated with the related gene expression patterns. Additionally, jasmonate (JA) and its precursor 12-oxophytodienoic acid increased their concentrations dramatically in red skin ginseng, suggesting the possible role of JA or JA signaling pathway in regulating red skin syndrome. Consistently, the expressions of 17 MYB transcription factors were differentially regulated in red skin ginseng. JA related cis-elements are widely distributed at their promoters. Taken together, our study revealed reduction of primary metabolism but increase of secondary metabolism in red skin ginseng. MYB transcription factors of JA signal pathway were supposed to mediate accumulation of anthocyanins and carotenoids that contributed to the development of red skin ginseng.

Rhizosphere analysis of field-grown Panax ginseng with different degrees of red skin provides the basis for preventing red skin syndrome

BackgroundGinseng red skin root syndrome (GRS) is one of the most common ginseng (Panax ginseng Meyer) diseases. It leads to a severe decline in P. ginseng quality and seriously affects the P. ginseng industry in China. However, as a root disease, the characteristics of the GRS rhizosphere microbiome are still unclear.MethodsThe amplicon bacterial 16 S rRNA genes and fungal ITS (Internal Transcribed Spacer) regions Illumina sequencing technology, combined with microbial diversity and composition analysis based on R software, was used to explore the relationship between soil ecological environment and GRS.ResultsThere were significant differences in the diversity and richness of soil microorganisms between the rhizosphere with different degrees of disease, especially between healthy P. ginseng (HG) and heavily diseased groups. The variation characteristics of microbial abundance in different taxa levels were analyzed. The interaction network of rhizosphere microorganisms of P. ginseng under GRS background was established. We also found that different P. ginseng rhizosphere microbial communities have multiple changes in stability and complexity through the established interaction network. Microbes closely related to potential pathogenic fungi were also identified according to the interaction network, which provided clues for looking for biological control agents. Finally, the Distance-based redundancy analysis (dbRDA) results indicated that total phosphorus (TP), available potassium (AK), available phosphorus (AP), catalase (CAT), invertase (INV) are the key factors that influence the microbial communities. Moreover, the content of these key factors in the rhizosphere was negatively correlated with disease degrees.ConclusionsIn this study, we comprehensively analyzed the rhizosphere characteristics of P. ginseng with different levels of disease, and explored the interaction relationship among microorganisms. These results provide a basis for soil improvement and biological control of field-grown in the future.

Surgical treatment strategy in patients suffering from post-traumatic coccygodynia

Clinical effectiveness of coccus removal in post-traumatic coccigodinia is evaluated. The study included 34 patients with diagnosed post-traumatic coccigodinia who underwent surgical treatment in resection or coccyx removal volume. A long history of trauma-related pain syndrome and ineffective conservative treatment were noted in all patients. The exclusion criteria were: inflammatory or oncological process, chronic urogenital diseases, previously undergoing operations on the lumbosacral spine, complicated by the course of the hernia of the intervertebral disc with root syndrome and neurological disorders. Before the operation, patients underwent manual examination, radiography (in direct and lateral projections) and computed tomography of the sacrum and coccyx, examination of the gynecologist (for women) and urologist (for men), examination of the proctologist, according to the indications magnetic resonance imaging of the spine in order to exclude hernia of the intervertebral disc with neural compression and dermoid cysts of the copcystic. Evaluation of treatment results was performed using a visual analogue pain scale and a verbal 5-point operation satisfaction scale. The observation period was from 1 year to 4 years. Cupping of pain syndrome after surgery was noted in 28 (82.4%) cases, in 6 (17.6%) patients there was a decrease in the intensity of pain syndrome with discomfort only after a prolonged sitting position. 5 (14.7%) patients were "satisfied" with surgery, 28 (82.4%) patients were "completely satisfied", in one (2.9%) case there was "doubtful satisfaction" with surgery. Thus, surgical treatment of coccigodinia in the volume of partial or complete coccyx removal is indicated in cases of ineffectiveness of conservative treatment in its post-traumatic instability. Surgical intervention leads to the cessation of pain syndrome and allows patients to return to their previous physical activity.

Зміни метаболізму пуринів при кістково-суглобовій формі раку легені

Актуальність. Актуальність проблеми набуває особливої значущості у зв’язку з почастішанням випадків метастазування раку легені (РЛ) у скелет, що істотно погіршує показники виживаності хворих. Ця так звана кістково-суглобова форма РЛ спостерігається в 30–40 % випадків захворювання. Пуринові основи належать до біомаркерів кісткових метастазів при РЛ, але їх діагностична та прогностична роль не вивчена. Мета: визначити стан пуринового метаболізму при кістково-суглобовій формі РЛ з оцінкою клініко-патогенетичної значущості виявлених змін. Матеріали та методи. Обстежено 123 хворих (усі чоловіки) віком від 24 до 79 років. Співвідношення периферичної і центральної форм раку становило 1 : 4, дрібноклітинного та недрібноклітинного гістологічного варіанта — 1 : 4, а IВ, IIА, IIВ, IIIА, IIIВ та IV стадій захворювання — 1 : 2 : 4 : 6 : 5 : 6. Кількість хворих із метастазами в лімфатичні вузли та віддалені органи становила 89 і 62 % відповідно. У сироватці крові вивчали рівні продуктів пуринового метаболізму — сечової кислоти, оксипуринолу, аденіну, гуаніну, ксантину, гіпоксантину, активності ксантиноксидази, ксантиндезамінази, аденозиндезамінази та 5-нуклеотидази. Результати. Дисметаболізм пуринів спостерігається у 98 % від числа хворих на РЛ, що проявляється підвищенням концентрації у крові сечової кислоти й оксипуринолу, активності ксантиноксидази й аденозиндезамінази. Показники пуринового обміну при РЛ відбивають ступінь тяжкості перебігу захворювання, пов’язані з локалізацією та морфологічною формою пухлинного процесу, проростанням у грудну стінку, трахею та стравохід, наявністю компресійного синдрому й обтураційного ателектазу. Кістково-суглобову форму РЛ встановлено у 32 % від числа хворих на РЛ, що супроводжується збільшенням показників урикемії, оксипуринолемії й аденінемії, що беруть участь в патогенетичних побудовах пухлинного процесу. Рівень аденіну (6-амінопурину) щодо метастазів РЛ у скелет має прогнознегативну значущість. Виживаність хворих з кістково-суглобовою формою РЛ гірша, ніж у інших пацієнтів.

Способ минимизации типичных осложнений при спинальной анестезии

Целью работы было исследовать влияние низкодозовой спинальной монолатеральной анестезии с использованием гипербарических растворов бупивакаина на кардиогемодинамику, респираторную депрессию, мышечную дрожь, постпункционную головную боль, транзиторный ишемический синдром и потребность в дополнительной внутривенной седации. Низкодозовая спинальная анестезия выявила больший протективный эффект в отношении кардиогемодинамики: стабильное состояние гемодинамики на этапах оперативного лечения при выполнении низкодозовой спинальной монолатеральной анестезии наблюдали в среднем в 3 раза чаще, чем при стандартной спинномозговой анестезии. Использование монолатеральной техники предотвращало опасные изменения респираторной функции на основном этапе в среднем в 2 раза больше, а по окончании операции — в 4 раза. Озноб и дрожь после монолатеральной спинномозговой анестезии наблюдали на основном этапе в 1,5 раза реже, а по окончании оперативного лечения — в 2,4 раза реже, чем при ортодоксальной спинномозговой анестезии.

Induced expression of rolC for study of its effect on the expression of genes associated with nicotine synthesis in tobacco

Background. Agrobacterium rhizogenes rol genes cause not only hairy root syndrome in plants, but also affect their secondary metabolism. There are cases of increasing of nicotine content in transgenic tobacco roots expressing rolC alone or in combination with other rol genes. In this work, we evaluated the change in the expression of nicotine synthesis genes and their regulators in response to the induction of expression of rolC.
 Materials and methods. Plant material was represented by three Nicotiana tabacum genotypes: cv. Samsun and two transgenic lines, derived from this cultivar and containing rolC under dexamethasone inducible promoter: A. rhizogenes rolC (Pdex-A4rolC) and N. tabacum rolC (Pdex-trolC) correspondingly. Fluidigm Biomark RT-PCR was used for evaluation of expression of QPT1, QPT2, A622, ODC, ADC, PMT1, PMT2, PMT3, PMT4, MPO1, MPO2, BBL, MATE1, MATE2, ARF6, ERF168, ERF189, A4rolC, NtrolC, and reference gene gapdh. HPLC-MS / MS analysis was used to determine content of nicotine and its derivatives in plant tissues.
 Results. Expression of PMT genes for the synthesis of the pyrrolidine ring, as well as the genes, controlling enzyme for final stages of nicotine synthesis, was higher in transgenic lines without induction of rolC expression. Regulatory genes were activated by dexamethasone in both transgenic and control lines, indicating the inapplicability of rolC dexamethasone induction for their study. The level of expression of PMT and MPO genes increased over time in transgenic dexamethasone-induced lines. Nicotine content decreased in transgenic dexamethasone-induced plants.
 Conclusions. The rolC gene does not play a primary role in the regulation of nicotine synthesis genes. The mechanism of regulation of different nicotine biosynthesis genes and TFs varies.

Effectiveness of percutaneous lumbar foraminoplasty in patients with lumbar foraminal spinal stenosis accompanying redundant nerve root syndrome: A retrospective observational study.

The clinical outcomes of redundant nerve root syndrome (RNRS) in patients with lumbar foraminal spinal stenosis (LFSS) are currently unknown. The purpose of this study was to evaluate the postprocedural outcomes of RNRS in LFSS after percutaneous lumbar foraminoplasty (PLF) and identify the factors associated with RNRS by comparative analysis between patients with and without RNRS.Patients with LFSS who underwent PLF were retrospectively analyzed. RNRS is defined as the presence of thick, elongated, and tortuous structures in the cauda equine associated with lumbar spinal stenosis. Based on the sagittal or transverse magnetic resonance imaging scans obtained before the PLF, the patients were stratified into 2 groups. Comparative analysis was performed between patients with RNRS (group R) and those without RNRS (group C).From March 2016 to January 2019, 8 of the 21 (38.1%) patients undergoing PLF showed signs of RNRS on magnetic resonance imaging images. PLF showed a tendency for less therapeutic effect with respect to changes in pain intensity in group R as compared to group C, but there were no statistically significant differences between the 2 groups. RNRS correlated with the cross-sectional area (CSA) of the dural sac and LFSS grade (P < .05). The CSA of the dural sac was smaller and the grade of LFSS was higher in group R than in group C.RNRS is commonly associated with lumbar spinal stenosis and could affect the treatment outcomes. Clinical outcomes in group R were not statistically different from those in group C, although group R showed slightly worse outcomes. The independent factors associated with RNRS were CSA of the dural sac and the LFSS grade.

Transcriptome analysis of field-grown Asian ginseng provides clues to environmental conditions and developmental mechanisms related to red skin root syndrome

Red skin root greatly decreases the quality and production of Asian ginseng (Panax ginseng). However, the molecular mechanisms of its origin and development are still obscure. The present study used Illumina high-throughput mRNA sequencing (RNA-seq) technology to conduct a comparative transcriptome analysis on field-sampled healthy and red skin root-affected ginseng fibrous roots. A total of 116,537 transcripts were assembled with an average length of 794 bp. Results of BLAST searches in the NCBI non-redundant protein database showed that the annotated transcripts were mostly enriched in plant species as well as the arbuscular mycorrhizae fungus Rhizophagus irregularis and the putative fungal pathogen Marssonina brunnea. With a cutoff of 1.5-fold (p<0.01), the fibrous roots of red skin root-affected ginseng showed 1856 up-regulated genes and 1581 down-regulated genes compared with the healthy ginseng roots. In addition to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enriched analyses, the environmental stimuli and phenolic compound metabolism underlying the origin and development of red skin disease were also discussed. The present study provides molecular clues to understanding the occurrence mechanisms of red skin root in ginseng.
