RESUMEN
This study explored the genetic characteristics of the whole genome sequences of coxsackie virus A6 strains in Jiangsu province from 2013 to 2022,and analyzed the genetic evolution of each coding region of the full-length genome.To in-vestigate why coxsackievirus A6 has replaced enterovirus A71 and coxsackievirus A16 as the most predominant etiological agent for HFMD in Jiangsu province,we selected 35 CVA6 isolates circulating in Jiangsu province during 2013-2022 for whole ge-nome sequence amplification and analysis.Sequence alignment,homology analysis,phylogenetic analysis and genetic recombi-nation were performed with the DNASTAR,MEGA7.0 and similarity plots 3.5.1 software packages.We analyzed the impor-tant amino acid sites of CV-A6 in the Pl region and 3D region.The nucleotide and amino acid similarities of 35 CV-A6 full-length genomes were 87.5%-99.6% and 97.0%-99.8%,respectively,and the nucleotide and amino acid sequence identity with the CV-A6 prototype strain was 80.3%-81.0% and 94.7%-95.3%,respectively.On the basis of phylogenetic analysis of VP1 region sequences,the 34 CV-A6 strains in this study belonged to the D3a genotype,and only one strain belonged to the D2 genotype.According to the phylo-genetic analysis of 3D region sequences,four recombinant forms(RFs),RF-A,RF-L,RF-K and RF-C,appeared primarily in 2013-2022 in Jiangsu province.Recombination analysis demonstrated that CVA6s,which was prevalent in Jiang-su from 2013 to 2022,had high similarity to the CVA6 prototype strain Gdula in the structured protein sequences.However,in the non-structured protein sequences and noncoding regions,similarities were higher among CVA6s and prototype strains of other EV-A types.Amino acid mutation site analysis showed that multiple amino acid sites in the Pl and 3D regions varied fre-quently with respect to the prototype strain Gdula.These differences might have resulted in small changes in the capsid struc-ture and potential receptor-binding sites.In conclusion,by analyzing the whole genome sequence of CV-A6,this study advances understanding of the gene recombination and genetic evolution relationship of CV-A6 in Jiangsu Province;in addition,it may explain possible reasons why CV-A6 has become the main pathogen of HFMD in recent years,and it provides basic data for the prevention and control of CV-A6.

OBJECTIVE@#To determine the clinical efficacy of different manipulation in the treatment of cervical instability in young people, and to analyze the risk factors of relapse of cervical instability in young people.@*METHODS@#From March 2021 to June 2022, the clinical data of 120 young patients with cervical instability were retrospectively analyzed. According to the different treatment methods, they were divided into rotation group (60 cases, 3 cases of loss) and tendon group (60 cases, 5 cases of loss). There were 25 males and 32 females in rotation-traction manipulation group;age ranged from 22 to 44 years old with a median of 28 years old;course of disease ranged from 0.17 to 120 months with amedian of 22 months. There were 22 males and 33 females in tendon-regulating manipulation group;age ranged from 21 to 42 years old with a median of 27 years old;course of disease ranged from 0.23 to 180 months with a median of 24 months. Both groups were treated for 2 weeks, once every other day for 7 times, and were followed up for 1 year. The clinical efficacy of the two groups was evaluated, and the visual analogue scale (VAS), neck disability index (NDI) were observed before and after treatment. One year after the course of treatment, patients with effective treatment were followed up to make statistics on recurrence. Patients with recurrence were included in the recurrence group, while those without recurrence were included in the non-recurrence group. Factors that may affect symptom recurrence were analyzed, and univariate and multivariate Logistic regression analysis were performed.@*RESULTS@#The 13 patients who failed the treatment (4 cases in the rotation-traction manipulation group and 9 cases in the tendon-regulating manipulation group) were not followed up. All the 99 patients who were effective in treatment were followed up ranged from 303 to 406 days with a median of 359 days. No complications occurred in all patients. There were significant differences in VAS and NDI between the two groups after treatment and before treatment (P<0.05), and there were significant differences in VAS and NDI between the two groups after treatment (P<0.05). Ninety-nine patients achieved follow-up, 56 (56.57%) relapsed and 43 (43.43%) did not. Univariate correlation analysis showed that NDI index, the time spent at the desk every day, the time spent using electronic products every day and angular displacement of anterior flexion before treatment in the relapse group were significantly higher than those in the non-relapse group (P<0.05). Logistic regression analysis showed that the time spent at the desk every day [OR=2.447, 95%CI(1.255, 4.771)], the time spent using electronic products every day [OR=1.892, 95%CI(1.066, 3.358)] and the angular displacement of anterior flexion of the cervical before treatment [OR=1.246, 95%CI(1.045, 1.485) ]were the risk factors for relapse.@*CONCLUSION@#Both rotation-traction manipulation and tendon-regulating manipulation can effectively treat cervical instability in young people, and rotation-traction manipulation has more advantages than tendon-regulating manipulation in improving cervical pain and cervical dysfunction in patients. The time spent at the desk every day, the time spent using electronic products every day, and the increase of cervical flexion angle displacement will increase the risk of relapse in patients.

OBJECTIVE@#To investigate whether Salvianolic acid A (SAA) can restore cartilage endplate cell degeneration of intervertebral discs and to identify the mechanism via regulation of micro-RNA.@*METHODS@#Cartilage endplate cells were isolated from lumbar intervertebral disc surgical samples and were treated with serum containing a series of concentrations of SAA (2, 5, and 10 ?M) for 24, 48, and 72 h to identify a proper dose and treatment time of SAA. The effect SAA on interlenkin-1β (IL-1β)-induced extracellular matrix degradation of cartilage endplate cells were analyzed by Alcian blue staining and assessment of the expression levels of ADAMTS-5, MMP3 and Col2a1. Further, the potential target miRNAs were preliminarily screened by micro-RNA sequencing combining qRT-PCR and Western blot, and then, the miRNAs mimics and inhibitors were used to verify the regulatory effect of SAA on potential target miRNAs.@*RESULTS@#The 10 μM SAA treatment for 48 h significantly enhanced the viability of cartilage endplate cells, and increased Col2a1 expression and glycosaminoglycan accumulation that were repressed by IL-1β, and reduced the effect of IL-1β on ADAMTS-5, and MMP3. Screening analysis based on micro-RNA sequencing and Venny analysis identified the downstream micro-RNAs, including miR-940 and miR-576-5p. Then, the miR-940-mimic or miR-576-5p-mimic were transfected into CEPCs. Compared with the SAA group, the expression of ADAMTS-5 and MMP3 increased significantly and the expression of COL2A1 obviously decreased after overexpression of miR-940 or miR-576-5p in CEPCs.@*CONCLUSION@#Salvianolic acid A attenuated the IL-1β-induced extracellular matrix degradation of cartilage endplate cells by targeting regulate the miR-940 and the miR-576-5p.

Fracture is one of the common diseases in the department of orthopaedics and traumatology. Jiegu Qili Tablets(Capsules) are a Chinese patent medicine commonly used to treat fractures in clinical practice, which has been included in the Class A drugs of the catalog of medicines covered by the National Medical Insurance System. However, no consensus or guideline has yet been developed to guide clinicians based on an evidence-based approach in detail, which has severely limited the clinical value of this drug. According to the guiding principle of evidence as the key, consensus as the supplement, and experience as the reference, a consensus was developed in strict accordance with the steps stipulated in the expert consensus on clinical applications of proprietary Chinese medicines. Based on literature review and questionnaire survey, the consensus was a timely summary of the existing clinical evidence on the treatment of fractures with Jiegu Qili Tablets(Capsules), and incorporated the treatment experience of a number of clinical experts. The preparation process took more than a year and the consensus(GS/CACM 293-2021) was officially released by the China Association of Chinese Medicine in September 2021, with the participation of multidisciplinary experts from 27 organizations of Chinese and Western medicine and research institutions. This article introduces the background and objectives of the consensus in detail, and describes the main process of proposal, drafting, expert consensus, and consultation. In particular, 5 consensus recommendations and 12 consensus suggestions are formed with regard to the key issues of indications, treatment timing, dose, duration, and safety in the clinical application of Jiegu Qili Tablets(Capsules) for the treatment of fractures, which guide and standardize the rational use by clinicians and improve the accuracy and safety of drugs.

OBJECTIVE@#To explore the characteristics of comorbidities in patients with osteoporosis(OP) and factors associated health-related quality of life, so as to provide decision-making reference for improving the ability of disease co-prevention and co-treatment and the patient's life-cycle quality of life.@*METHODS@#From November 2017 to July 2018, clinical information and biological samples from residents in 10 communities in Chaoyang District and Fengtai Distric of Beijing were collected, and bone density testing was conducted. Based on the Charlson comorbidity index (CCI), the comorbidity of the population was quantified, and grouped according to factors such as gender, age, and the differences between the groups were explored. Combined with the clinical information of patients, the difference characteristics of comorbidity and non-comorbidity population were analyzed. Pearson/Spearman correlation analysis and binary Logistic regression analysis were used to explore the factors affecting the health-related quality of life in patients with OP.@*RESULTS@#Among the 521 OP patients, 121 patients had no comorbidities, and there were 153, 106, 65, and 30 patients with one, two, three, and four comorbidities, respectively, 46 patients with 5 or more kinds of comorbidites. Hypertension was the most common comorbidity in OP patients, accounting for 21.60%;followed by hyperlipidemia, accounting for 13.51%. The most common combination of the two diseases was hypertension plus hyperlipidemia (64 cases, 12.28%). Through the analysis of differences between age groups, it was found that the older patients, showed higher the CCI, and the difference between groups was statistically significant(Z=1.93, P=0.05). There were significant differences in the total EQ-5D score and the dimensions of anxiety and depression between patients with comorbidities (CCI≠0) and non-comorbidities (CCI=0) (Z=-2.67, P=0.01;Z=-2.44, P=0.02). Correlation analysis found that CCI, history of fracture, history of falls, hip bone mineral density T value and parathyroid hormone were all related to the health-related quality of life in OP patients (P<0.05). Binary Logistic regression analysis suggested that the right hip bone mineral density T value (P=0.02), CCI (P=0.01), fracture history (P=0.03) and fall history (P=0.01) were the risk factors that affect the health-related quality of life in OP patients.@*CONCLUSION@#The burden of comorbidities among middle-aged and elderly OP populations in Beijing is relatively heavy, and the health management of such populations should be further strengthened, specifically the combination of multiple comorbidities should be given high priority. Comorbid factors are of great importance for the diagnosis and treatment strategy of OP patients, which could further improve the quality of life.

Traditional Chinese medicine has unique advantages in the treatment of degenerative bone and joint diseases, and its widely used in clinical practice. In recent years, many scholars have conducted a large number of basic studies on the delay of intervertebral disc degeneration by herbal compound and monomeric components from different perspectives. In order to further elucidate its mechanism of action, this paper summarizes the in vivo and in vitro experimental studies conducted at the level of both herbal compound and single components, respectively, in order to provide references for the basic research on the treatment of lumbar intervertebral disc degeneration by Chinese medicine. A summary shows that commonly used herbal compound prescriptions include both classical prescriptions such as Duhuo Jisheng Decoction, as well as clinical experience prescriptions such as Yiqi Huoxue Recipe. Angelicae Sinensis Radix, Chuanxiong Rhizoma, Rehmanniae Radix Praeparata, Achyranthis Bidentatae Radix, and Eucommiae Cortex were used most frequently. Tonic for deficiency and blood stasis activators were used most frequently. The most utilized monomeric components include icariin, ginsenoside Re, salvianolic acid B and aucubin. The main molecular mechanisms by which herbal compound and monomeric components delay of lumbar intervertebral disc degeneration include improving the intervertebral disc microenvironment, promoting the synthesis of aggregated proteoglycans and type Ⅱ collagen in the intervertebral disc, reducing the degradation of the extracellular matrix, and inhibiting apoptosis in the nucleus pulposus cells, etc. The main signaling pathways involved include Wnt/β-catenin signaling pathway, MAPK-related signaling pathway, mTOR signaling pathway, Fas/FasL signaling pathway, PI3 K/Akt signaling pathway, NF-κB signaling pathway, JAK/STAT signaling pathway, and hedgehog signaling pathway, etc.

Lyophilized plasma has a certain advantage in emergency situation, such as war wound treatment. However, lyophilized plasma has two major problems, plasma pathogen pollution and mass loss after lyophilized. Studies have shown that plasma pathogen inactivation technology targeting pathogen envelope or nucleic acid can ensure its safety, and adding citric acid and glycine to plasma can effectively maintain pH and protein activity of plasma after reconstitution. At present, there are three kinds of lyophilized plasma products on the market abroad, but none for China. Therefore, understanding the research progress of lyophilized plasma may contribute to the development of similar products in China.

To evaluate the clinical efficacy and safety of Shentong Zhuyu Decoction in the treatment of lumbar disc herniation, in order to provide evidence for its clinical application. PubMed, Cochrane Library, EMbase, CNKI, WanFang, VIP, CBM and Clinical Trials.gov databases were sysmatically retrieved. Two researchers independently searched, screened and extracted data. Randomized controlled trials in line with the inclusion criteria were included in the study. The article quality was assessed with the bias risk tool in the Cochrane Handbook. Meta-analysis was performed using RevMan 5.3. A total of 604 articles were obtained from the retrieval, and 824 patients in 9 studies were finally selected through screening. The course of treatment was about 1 month, and all of the studies were completed in China. Meta-analysis showed that the efficacy of Shentong Zhuyu Decoction in the treatment of lumbar disc herniation was better than that of the control group(RR=1.19, 95%CI[1.12, 1.26], P<0.000 01), including the comparison with Yaotongning Capsules(RR=1.10, 95%CI[1.02, 1.19], P=0.01) and diclofenac sodium tablets(RR=1.26, 95%CI[1.11, 1.44], P=0.000 4). In VAS pain score, Shentong Zhuyu Decoction had also obvious advantages(MD=-3.70, 95%CI[-6.31,-1.09], P=0.005). In addition, the number of adverse events in the Shentong Zhuyu Decoction group was lower than that in the control group. Shentong Zhuyu Decoction can effectively alleviate discomfort symptoms of patients with LDH. It has an obvious clinical efficacy and less adverse reactions. However, restricted by the quality of the included literatures, prospective, multi-center, large-sample-size randomized controlled trials are still needed to further improve the clinical evidence of the effect of Shentong Zhuyu Decoction in the treatment of LDH.

The aim of this paper was to investigate the key targets and mechanism of "Epimedii Folium-Paeoniae Radix Alba" in the treatment of lumbar disc herniation by means of network pharmacology. The currently recognized databases and analysis software at home and abroad were used to construct the network from drugs and diseases. The chemical components of Epimedii Folium and Paeo-niae Radix Alba were collected by using databases such as TCMSP, while their active components were determined and the action targets were predicted according to threshold screening and literature reports. The genes for lumbar disc herniation were collected by using GeneCards, OMIM, and DisGeNET databases. The drug targets were mapped to disease targets, and protein interaction network analysis for key targets, GO function enrichment analysis and KEGG signaling pathway enrichment analysis were performed. Finally, 23 active components of Epimedium Folium and 13 active components of Paeoniae Radix Alba were determined, and a total of 624 drug targets were obtained. After standardization, 214 drug targets were obtained. In addition, 306, 2 and 5 related targets of lumbar disc herniation were collected from GeneCards, OMIM, and DisGeNET database, respectively, and a total of 293 disease targets were obtained after deduplication. After the mapping of drug target and disease target, 44 common targets were obtained. PPI protein interaction network analysis showed that IL-6, TNF, AKT1, MAPK1, and VEGFA may be the core targets for the treatment of lumbar disc herniation. GO enrichment analysis identified 56 items(P<0.05), among which biological processes mainly included immune response, apoptosis, etc.; cell components mainly included extracellular space, extracellular region, etc.; molecular functions mainly included cytokine activity, metallopeptidase activity and so on. Through KEGG pathway enrichment analysis, 91 signaling pathways related to inflammation, metabolism, and senescence were identified, mainly including IL-17 signaling pathway and TNF signaling pathway and so on. "Epimedii Folium-Paeoniae Radix Alba" showed the characteristics of multi-channel and multi-target for the treatment of lumbar disc herniation. This study preliminarily explored the key targets for its role and the biological processes and signaling pathways involved. It was found that it may play a therapeutic role by affecting inflammation and immune regulation, which laid the foundation for further experimental verification.

BACKGROUND: Animal models are critical to study the mechanism, prevention and treatment of intervertebral disc degeneration (IDD). Therefore, constructing an ideal animal model of IDD is the key to further study IDD. OBJECTIVE: To review the selection and construction methods of the IDD model, so as to select and construct an ideal animal model of IDD. METHODS: A retrieval of CNKI, WanFang, VIP, SinoMed and PubMed databases was performed for the articles published before December 2016. The keywords were "intervertebral disc degeneration, animal model" in English and Chinese, respectively. All the articles were selected from the authoritative magazines, and finally 56 eligible articles were included. RESULTS AND CONCLUSION: There are many kinds of animals used for constructing the IDD model, including small and large animals. The former has a small volume of intervertebral disc that is beneficial for nutrient and metabolite transport,so it can be used for long-term in vitro culture.The latter has a large volume of intervertebral disc,which is appropriate for biomechanical study.The animal models of IDD include in vivo and in vitro models:the in vivo models include the changed biomechanics,destroyed physical structure,spontaneous and systemic disease models;the in vitro models include in vitro cellular and organ models.However,there is still a lack of an ideal animal model that can fully simulate human IDD. Noticeably, similarity, comparability, economy, feasibility, reliability and controllability should be considered.
RESUMEN
BACKGROUND: As a reliable biomechanical model, human fresh isolated cervical specimens provide the basis for studying the pathogenesis of cervical vertigo from the perspective of blood flow of vertebral artery.There is a lack of an in vitro cervical model that can simulate the physiological state of the cervical vertebrae and achieve complex posture, as well as can measure the blood flow of vertebral artery. OBJECTIVE:To study the influence of variant position of human fresh isolated cervical vertebrae on the blood flow of vertebral artery in vitro through constructing the fresh specimen of cervical vertebral artery determination model. METHODS: Six human fresh isolated cervical specimens were selected for constructing the vertebral artery determination model. The pressure of human vertebra artery was simulated by pressure pump. The change of normal saline height was measured by digital motion capture system dynamically under different positions. RESULTS AND CONCLUSION: (1) Eight vertebral arteries in the six models were in good condition. (2) The vertebral artery flow under neutral position was significantly richer than that under contralateral rotation-anteflexion and ipsilateral/contralateral rotation-postexion (P <0.05). (3) The vertebral artery flow under contralateral rotation-anteflexion and rotation-postexion was significantly poorer than that under natural position, ipsilateral rotation and ipsilateral rotation-anteflexion (P < 0.05). (4) In summary, the cervical vertebral artery determination model is constructed successfully that can simulate the influence of the position on vertebral artery flow. Additionally, different positions of rotation make a different effect on vertebral artery flow.
RESUMEN
<p><b>OBJECTIVE</b>To compare effect of serum of Bushen Huoxue prescription on rabbit with intervertebral disc motion segments in vitro culture.</p><p><b>METHODS</b>Twenty-four New Zealand white rabbits aged from 4 to 6 months and weighted from 2.5 to 3 kg were divided into medicated group and control group, 7 in each group. Rabbits were excuted under condition of asepsis, 28 spinal motion segments were taken out in each group, and segments were loaded in spinal motion segments in vitro and cultured in culture apparatus. Nutrient solution of medicated group contain 10% serum of Bushen Huoxue prescription, and 10% blank serum in control group. Seven discs between two groups were taken out and observed by histomorphology, proteoglycan PAS/AB stining, collagen II immunohistochemical staining, AGG, Col2aI by PCR test before culture and on the 3th, 7th and 14th day after culture.</p><p><b>RESULTS</b>Histomorphology results showed the formation of medicated group was better than that of control group at 1 week after culture. PAB/AB test results showed content of poteoglycan between two groups were decreased. Imunohistochemical results showed content of collagen II in medicated group were obviously increased than that of control group at 3 days, but decreased obviously at 1 week than that of control group. PCR results showed expression of Agg in medicated group was obviously decreased than that of control group, but no statistical significance between two groups on the 7 th and 14 th day. Expression of Col2aI between two groups at 3 days were increased, and medicated group increased obviously more, while there were no significant difference between two groups.</p><p><b>CONCLUSIONS</b>Serum of Bushen Huoxue prescription could delay intervertebral disc degeneration at short time for it is relate with improving circulation, inhibiting inflammatory, regulating extracellular matrix, so the prescription plays an important role in early prevention and treatment for intervertebral disc degeneration.</p>
RESUMEN
<p><b>OBJECTIVE</b>To evaluate the stability of teaching robot of rotation-traction manipulation.</p><p><b>METHODS</b>Operators were required to get the hang of rotation-traction manipulation and had clinical experience for over 5 years. The examination and data processing of the ten operators in our research were collected by the teaching robot of rotation-traction manipulation. Traction, pulling force, maximum force, pulling time, rotational amplitude and pitch range were recorded and compared for five times(G1, G2, G3, G4 and G5). The qualification rates were analyzed to evaluate the stability of teaching robot of rotation-traction manipulation.</p><p><b>RESULTS</b>Nonconforming items were found in G1 and G2, for instance, pulling force(=0.074), maximum force(=0.264) and rotational amplitude (=0.531). There was no statistically difference. None nonconforming item was found in G3, G4 and G5. All data were processed by SPSS and One-way ANOVA was used to analysis. Pulling force was found statistically different in G1, compared with G4 and G5(=0.015,=0.006). Maximum force was found statistically different in G1, compared with G4 and G5 (=0.021,=0.012). None differences were found in other comparisons (>0.05).</p><p><b>CONCLUSIONS</b>The teaching robot of rotation-traction manipulation used in our research could provide objective and quantitative indices and was considered to be an effective tool of assessing the rotation-traction manipulation.</p>
