BACKGROUND:The evaluation and management of cervical vascular pathologies before orthopedic manual therapy have great significance for reducing risks,ensuring patients'interests and promoting optimal clinical decision-making.However,the research and exploration of this field in China are still in its infancy.In 2020,the International Federation of Orthopaedic Manipulative Physical Therapists(IFOMPT)released the International Framework for Examination of the Cervical Region for potential of vascular pathologies of the neck prior to Orthopaedic Manual Therapy(OMT)Intervention:International IFOMPT Cervical Framework(2020).This framework has important references and guiding values for the clinical practice of cervical manipulation in China. OBJECTIVE:To integrate and interpret the core content of the framework,to provide a reference for the clinical practice of cervical manual therapy in China. METHODS:On the basis of a full study of the framework,the authors interpret the core content of the framework from eight aspects including clinical reasoning,patient history,planning the physical examination,physical examination,risk and benefit.Meanwhile,seven databases including PubMed,EMbase,Cochrane Library,CNKI,WanFang,VIP and China Biomedical Literature Service System databases were searched by computer to screen clinical practice guidelines and expert consensus on neck pain.Through longitudinal comparison of multiple high-quality guidelines and consensus,the authors combine with the clinical practice in China to carry out discussion and analysis. RESULTS AND CONCLUSION:This framework expounds the management strategy and implementation path of cervical vascular disease evaluation before cervical manipulation from multiple dimensions,suggesting that we should improve clinicians'attention to cervical vascular disease evaluation before manipulation,and construct evaluation criteria and implementation path with Chinese clinical characteristics.Meanwhile,we should further carry out basic scientific research with multidisciplinary techniques and promote shared decision-making and teaching model innovation to achieve the best clinical decision.

BACKGROUND:Previous studies on cervical instability failed to explain the dynamic and static interaction relationship and pathological characteristics changes in the development of cervical lesions under the traditional imaging examination.In recent years,the emerging nuclear magnetic resonance imaging(MRI)radiomics can provide a new way for in-depth research on cervical instability. OBJECTIVE:To investigate the application value of MRI radiomics in the study of cervical instability. METHODS:Through recruitment advertisements and the Second Department of Spine of Wangjing Hospital,China Academy of Chinese Medical Sciences,young cervical vertebra unstable subjects and non-unstable subjects aged 18-45 years were included in the cervical vertebra nuclear magnetic image collection.Five specific regions of interest,including the intervertebral disc region,the facet region,the prevertebral muscle region,the deep region of the posterior cervical muscle group,and the superficial region of the posterior cervical muscle group,were manually segmented to extract and screen the image features.Finally,the cervical instability diagnosis classification model was constructed,and the effectiveness of the model was evaluated using the area under the curve. RESULTS AND CONCLUSION:(1)A total of 56 subjects with cervical instability and 55 subjects with non-instability were included,and 1 688 imaging features were extracted for each region of interest.After screening,300 sets of specific image feature combinations were obtained,with 60 sets of regions of interest for each group.(2)Five regions of interest diagnostic classification models for cervical instability were initially established.Among them,the support vector machine model for the articular process region and the support vector machine model for the deep cervical muscle group had certain accuracy for the classification of instability and non-instability,and the average area under the curve of ten-fold cross-validation was 0.719 7 and 0.703 3,respectively.(3)The Logistic model in the intervertebral disc region,the LightGBM model in the prevertebral muscle region,and the Logistic model in the superficial posterior cervical muscle region were generally accurate in the classification of instability and non-instability,and the average area under the curve of ten-fold cross-validation was 0.650 4,0.620 7,and 0.644 2,respectively.(4)This study proved the feasibility of MRI radiomics in the study of cervical instability,further deepened the understanding of the pathogenesis of cervical instability,and also provided an objective basis for the accurate diagnosis of cervical instability.

Objective:To retrospectively analyze the molecular epidemiological features and genetic recombination of coxsackievirus A4 (CVA4) strains isolated in Jiangsu from 2015 to 2022.Methods:Throat or anal swab samples were collected from patients with herpangina or hand, foot and mouth disease (HFMD). Real-time PCR was used to detect CVA4. A comprehensive and systematic phylogenetic analysis was conducted based on 72 whole genomes and 99 VP1 sequences of CVA4 strains. Several bioinformatics software including DNAStar, MEGA7.0 and Similarity plots3.5.1 was used for analysis of homology, genetic recombination and amino acid variation sites.Results:Four genotypes (A, B, C and D) and five sub-genotypes (C1-C5) of CVA4 were identified based on the VP1 nucleotide sequences. C2 was the predominant sub-genotype causing HFMD. The Jiangsu strains showed high homology with the CVA4 prototype in the P1 region, and higher identity with other strains of enterovirus group A (EV-A) in the P2 and P3 regions. Genetic recombination analysis revealed that the Jiangsu strains had three genetic recombination patterns with other EV-A epidemic strains in the P2, P3 and 3′-UTR regions. These recombination patterns took place during the sustained and widespread circulation of CVA4 in people and increased the transmissibility of CVA4.Conclusions:This study analyzes the phylogenetic and molecular features of 28 whole genomes of Jiangsu CVA4 strains, which helps to better understand the genomic diversity of CVA4. By analyzing the genetic recombination and amino acid mutations in the VP1 region, this study elucidates the evolution and transmission of CVA4, which is conducive to the control and prevention of CVA4 infection.

ObjectiveTo explore the mechanism of Zhuangyao Tongluo Formula（壮腰通络方，ZTF） in delaying intervertebral disc degeneration. MethodsM1 macrophages were induced from THP-1 cells using LPS， IFN-γ and PMA. The induced M1 macrophages were then co-cultured with nucleus pulposus cells in a transwell system. Fetal bovine serum was used as the control serum， and the effects of different concentrations （5%， 10%， 15%， 20%） of serum from rats treated with ZTF on the activity of M1 macrophages and nucleus pulposus cells were analyzed using MTT assay. Experiment 1 was established， including the nucleus pulposus cell control group， M1 macrophage control group， nucleus pulposus cell + ZTF group， nucleus pulposus cell + TNF control group， nucleus pulposus cell + TNF + ZTF group， co-culture group， and co-culture + ZTF group. The levels of IL-1β， and IL-18 in the culture supernatant were detected using ELISA. The mRNA expression of IL-1β and IL-18 in nucleus pulposus cells was detected using qPCR. Additionally， the expression of GSDMD protein in nucleus pulposus cells was detected using cell immunofluorescence. In experiment 2， co-culture groups were constructed using TNF-α overexpression （OE） or empty vector （EV） plasmids， including co-culture group， TNF-EV + co-culture group， TNF-EV co-culture group + ZTF， co-culture + ZTF group， TNF-OE co-culture group + ZTF， and TNF-OE + co-culture group. The mRNA and protein expression of TNF-α in M1 cells in each group were detected using qPCR and WB. ResultsThe ZTF with 10% serum was selected for subsequent experiments. The results of experiment 1 showed that compared to the control group of nucleus pulposus cells， there was no statistically significant difference in the levels of IL-1β， IL-18， mRNA， and GSDMD expression in the nucleus pulposus cells + ZTF group （P＞0.05）. However， the TNF-α + co-culture group showed a significant increase in IL-1β， IL-18 levels， mRNA， and GSDMD expression （P＜0.01）. When compared to the co-culture group， the ZTF+ co-culture group showed a significant decrease in IL-1β， IL-18 levels， mRNA， and GSDMD expression （P＜0.01）. The results of experiment 2 showed that there was no statistically significant difference in TNF-α mRNA and protein expression between the empty vector plasmids + co-culture group and the co-culture group （P＞0.05）. Compared to the empty vector + co-culture group， the expression of TNF-α mRNA and protein was significantly reduced in the empty vector co-culture + ZTF group （P＜0.01）. Compared to the co-culture group and the empty vector + co-culture group， the expression of TNF-α mRNA and protein was significantly reduced in the co-culture + ZTF group （P＜0.01）. Compared to the co-culture + ZTF group， the expression of TNF-α mRNA and protein significantly increased in the overexpression vector co-culture + ZTF group （P＜0.01）. Compared to the overexpression vector co-culture + ZTF group， the expression of TNF-α mRNA and protein significantly increased in the overexpression vector co-culture group （P＜0.01）. ConclusionZTF serum can inhibit the TNF-α-induced apoptosis of nucleus pulposus cells and delay lumbar disc degeneration by reducing the expression of TNF-α in M1 macrophages.

Objective:To analyze the whole-genome sequences of coxsackievirus A10 (CVA10) strains isolated in Jiangsu Province from 2015 to 2022 and their molecular epidemiological characteristics.Methods:Forty-five CVA10 isolates circulating in Jiangsu Province during 2015 to 2022 were selected for whole-genome sequencing. Phylogenetic trees were constructed based on the whole genome, VP1, P1, P2 and P3 sequences of CVA10 strains. Bioinformatics software, including DNAStar, MEGA7.0 and Similarity plots3.5.1, was used for analysis of homology, genetic recombination and major amino acid variation sites.Results:The nucleotide and amino acid sequence homology of the whole-genome sequences of 45 CVA10 strains was 90.3%-99.1% and 97.9%-99.8%, respectively. The nucleotide sequence homology of P1 region was the highest (92.1%-100.0%), while the nucleotide sequence homology of P3 region ranged from 84.7% to 100.0%. In contrast to the diversity of nucleotide sequences, the amino acid sequences of each region were conserved. A phylogenetic analysis based on the complete VP1 sequences of CVA10 strains revealed eight genotypes: A-H. The CVA10 isolates in Jiangsu Province and other prevalent strains in China mainly belonged to genogroup C. Results of the phylogenetic analysis based on the whole-genome sequences and complete VP1 sequences were consistent. Phylogenetic analysis bases on different gene segments and Simplot recombination analysis revealed that Jiangsu isolates GD07/Lianyungang/2017 and N180/Suqian/2016 showed high homology with the CVA10 prototype in the P1 region, but had recombination sites with other strains of enterovirus group A in the P2, P3, 5′-UTR and 3′-UTR regions. Compared with the prototype strain AY421767/Kowalik/2004, the Jiangsu isolates showed frequent variations in the VP1 region and many other major amino acid sites, which might result in some imperceptible changes in capsid structure and potential receptor-binding sites.Conclusions:By analyzing the evolution and genetic recombination features of CVA10 strains at the genome level in Jiangsu Province, this study elucidated the influence of genetic recombination and amino acid site mutation on CVA10 infection, providing basic data for the prevention and control of hand-foot-mouth disease in Jiangsu Province.

<p><b>OBJECTIVE</b>To investigate the hepatitis C virus (HCV) infection rate among general population in Jiangsu province and to analyze the main risk factors for HCV infection.</p><p><b>METHODS</b>Subjects in 3 counties were surveyed by stratified cluster random sampling in the National Major Science and Technology Projects demonstration area in Jiangsu province. Interview was carried out with uniformly- designed questionnaires. Blood samples were collected and anti-HCV tested. Data were analysed under SPSS 13.0. Case-control study was conducted on two groups with subjects under 1:4 matching by sex, age, village of residence and status of HCV infection. Cox's proportional hazards regression analysis was then performed to analyze the risk factors for HCV infection.</p><p><b>RESULTS</b>The positive rate of anti-HCV was higher in females (0.965%, 95%CI:0.899%-1.035%) than in males (0.572%, 95%CI:0.517%-0.632%). Significant differences were noticed among the positive rates of anti-HCV in the three counties (0.131%, 95%CI:0.103%-0.164%;0.316%, 95%CI: 0.268%-0.370%; 2.173% , 95% CI:2.039%-2.315% , respectively). Peak prevalence of anti-HCV (1.577%, 95%CI:1.425%-1.740%) was observed among persons at 50-59 years of age. Bottom rate (0.161%, 95%CI:0.125%-0.204%) was observed below 30 years of age. High anti-HCV positive rate was detected in people with lower education background or belonged to 'floating population'. Factors as having histories of hospitalization (OR = 3.049, 95% CI:1.322-7.036), blood transfusion (OR = 14.319, 95%CI:2.318-88.459) or sharing razor (OR = 3.604, 95%CI:1.096-11.851) were risk factors of HCV infection in the area with the lowest anti-HCV positive rate. In another county, factor as having histories of 'blood products transfusion' (OR = 7.202, 95% CI:1.170-44.310) appeared important while in the third county, having history of 'blood donation' (OR = 7.496, 95%CI:6.121- 9.180); 'blood transfusion' (OR = 2.305, 95%CI:1.578-3.369) and 'invasive physical examination' (OR = 1.258, 95% CI:1.021-1.549) appeared to be important. Age seemed a risk factor for HCV infection. "Sharing razor" was a specifically important risk factor among the 30- year-olds. "Having received acupuncture" was noticed a risk factor only among people at 50-59 years of age while "Having received invasive physical examination" was important in the 50-59 and 60-69 year-olds.</p><p><b>CONCLUSION</b>High anti-HCV positive rate was observed in people at middle of aged population, as well as in those with poor education or under 'floating'. Unsafe blood donation or having received blood-product transfusion might be the risk factors in the last decades. Factors as sharing razor, having received acupuncture or invasive examination might be specifically risky in different populations.</p>

In males,the mean of the BUN; FG and TG were significant different among the different age groups (the control group: F = 3. 500, P ＜ 0.05; F = 5. 607, P ＜0.05 ;F =3. 378,P ＜0.05 ;the hyperuricemia group: F= 15.400,P ＜0.05 ;F =5. 111 ,P ＜0.05 ;F = 11. 143 ,P ＜0.05), the positive rate of BUN, Cr, FG and TG were significant different among the different age groups (control group:χ2 = 17. 112,P ＜ 0.05;χ2 =7. 807,P ＜0.05 ;χ2 = 17. 829,P ＜0.05;χ2=8.433,P ＜0.05; hyperuricemia group:χ2 =35. 587,P ＜0.05 ;χ2 =83. 005 ,P ＜0.05 ;χ2 =41. 639,P ＜0.05 ;χ2 =31. 466,P ＜0.05). In the same age group,the mean and the positive rate of BUN and Cr were significantly higher in the hyperuricemia group than in the control group(P ＜ 0.05). The mean of TG was significantly higher in every age group of the hyperuricemia group than controls (P ＜ 0.05), but the positive rate had no significant differences in the age group of ≥ 70 years (P ＞0.05). The mean and the positive rate of FG and TC were significant differences in middle age group between the hyperuricemia and the control group (P ＜ 0.05), but were no differences in elder age group(P ＞ 0.05). In females,the mean and positive rate of Cr, BUN, FG,TG and TC were significant different in different age groups of the controls(BUN:F = 13. 759,P ＜0.05;χ2 = 19. 491 ,P ＜0.05; FG: F = 13. 554,P ＜0.05;χ2 = 33. 438,P ＜0.05;TG:F= 18. 160,P ＜0.05;χ2 = 16. 978,P ＜0.05;TC: F = 37. 647,P ＜0.05;χ2 =60.547,P ＜0.05) ,but in the hyperuricemia group that were only significant difference in BUN, Cr and TC (BUN:F = 5. 830, P ＜ 0.05; χ2 =11.941,P＜0.05;Cr:F=4.057,P ＜0.05;χ2 =20.097,P＜0.05;TC:F=7.934,P ＜0.05;χ2 = 16.405,P ＜0.05). In same age group compared of all the indices were similar with male. Conclusions The mechanism of serum uric acid increasing are different in middle age and elderly age. In middle age, it is metabolic disturbance. However,in elderly age it is descending of the kidney function.

BACKGROUND:According to the thrust of document issued by State Drug Administration, the clinical experiment was carried onfufang duzhongjiangu keli (compound) (Bo Si Zhuang) in treatment of knee joint osteoarthritis.OBJECTIVE: To evaluate the improvement of the compound in treatment of knee joint osteoarthritis and its safety.DESIGN: Zhuanggu guanjie wan (bolus) was taken as controlled drug and double blind, double-simulation randomized method was designed.SETTING: Fujian Institute of Chinese Medicine, Guananmen Hospital of China Academy of Traditional Chinese Medicine, Institute of Orthopedics and Traumatology of China Academy of Traditional Chinese Medicine and Beijing Hospital of Chinese Medicine.PARTICIPANTS: Clinical experiment Ⅱ was performed since December 19, 1999, in which, 200 cases of knee joint osteoarthritis were observed and divided into compound group (100 cases) and bolus group (100 cases).From December 1999 to March 2000, clinical experiment Ⅲ was performed to observe 400 cases of knee joint osteoarthritis, in which, 300cases were divided in compound group and 100 cases in bolus group. All of cases were diagnosed by X-ray test and differentiated in Chinese medicine as insufficiency of liver and kidney and stasis of tendons and vessels. All of patients were in the known of experiment.METHODS: In compound group, fufang duzhong zhuanggu keli (1bag/time, 3 times/day) + simulated dosage of zhuanggu guanjie wan were administrated. In bolus group, fufang duzhong zhuanggu keli simulated dosage + zhuanggu guanjie wan (1bag/time, twice/day) were administrated.Double blind and double-simulation randomized control experiment was given in one-month treatment to observe clinical therapeutic effects.MAIN OUTCOME MEASURES: Evaluation on clinical indexes of joint function ,clinical therapeutic effect, syndrome score in Chinese medicine and adverse reaction.RESULTS: Totally 600 cases employed had all accomplished datum collections, no dropped-off case. ① The total effective rate of compound group was superior remarkably to bolus group (92.%, 82%). ② The result of joint function in compound group was superior remarkably to that of bolus group. ③ Concerning to improvement of syndromes in Chinese medicine, the result in compound group was superior to that of bolus group (the decreased integrals were 7.03±3.38 and 5.43±3.16 respectively). ④No obvious harmful effect presented during experiment.CONCLUSION: Fufang duzhong jiangu keli improves the symptoms of osteoarthritis of knee safely and effectively.
