ABSTRACT

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

ABSTRACT

Jupi Zhurutang originated from Synopsis of the Golden Chamber (《金匮要略》), which consists of Pericarpium Citri Reticulatae, Caulis Bambusae in Taenia, Ginseng Radix et Rhizoma, Zingiberis Rhizoma Recens, Jujubae Fructus, and Glycyrrhizae Radix et Rhizoma and is used to treat retching. It has been put on the list of Catalogue of Ancient Classical Prescription (First Batch) released by National Administration of Traditional Chinese Medicine. With the bibliometric method, we searched the medical classics containing Jupi Zhurutang and systematically examined the information on the origin of the prescription, the indications, compatibility rule, medicinals in the prescription, dosage and usage, processing method, and decocting method. It was found that there are many versions of Jupi Zhurutang, and there are common grounds of main symptoms, pathogenesis, composition and dosage between the same prescription with different names and different prescriptions with the same name. The prescription which is closest to the original version in Synopsis of the Golden Chamber is mainly used for the treatment of stomach deficiency and qi counterflow without obvious cold or heat. According to the weights and measures, ratio of Pericarpium Citri Reticulatae, Caulis Bambusae in Taenia, Radix Ginseng, Rhizoma Zingiberis Recens, and Radix Ginseng in Synopsis of the Golden Chamber is approximately 6∶2∶8∶5∶1. The Jupi Zhurutang derived from other ancient classics such as Yanshi Jisheng Fang(《严氏济生方》) is a different prescription for hiccups caused by the stomach heat, and the ratio of Pericarpium Citri Reticulatae to Caulis Bambusae in Taenia in this prescription is about 1∶1. It is also found that cold herbs such as Red Poria, Eriobotryae Folium and Ophiopogon Japonicus are added to the formula in later generations. Therefore, the Jupi Zhurutang used in modern times is mostly modified and different from that in Synopsis of the Golden Chamber. This study summarizes the historical evolution of Jupi Zhurutang and identifies the key information, with a view to providing a reference for the rational modification of this prescription in clinical settings and further research.

ABSTRACT

Pediatric acute hyperextension spinal cord injury (SCI) named as PAHSCI by us, is a special type of thoracolumbar SCI without radiographic abnormality and highly related to back-bend in dance training, which has been increasingly reported. At present, it has become the leading cause of SCI in children, and brings a heavy social and economic burden. Both domestic and foreign academic institutions and dance education organizations lack a correct understanding of PAHSCI and relevant standards, specifications or guidelines. In order to provide standardized guidance, the expert team formulated this guideline based on the principles of science and practicability, starting from the diagnosis, differential diagnosis, etiology, admission evaluation, treatment, complications and prevention. This guideline puts forward 23 recommendations for 14 related issues.

ABSTRACT

Objective: To measure and analyze the morphometric changes in the anterior alveolar bone during treatment and retention stage after retraction in bimaxillary adults using cone-beam CT(CBCT). Methods: Fifteen adult patients, four males and 11 females, aged 19 to 28 years[(22.2±3.1) years], who have completed orthodontic treatment and extracted four first premolar teeth for retraction in the Department of Orthodontics, The Affiliated Stomatological Hospital of Nanchang University from January 2016 to December 2018 were selected. CBCT was taken to assess the labial and palatal vertical bone level, total bone thickness at crest area, middle root area and apical area in pre-treatment (T1), post-treatment (T2) and at follow-up (maintained for more than two years) (T3). The differences in alveolar bone morphology at different stages were compared by single factor repeated measure ANOVA, and Pearson correlation analysis was performed on the amount of alveolar bone change in treatment stage and retention stage. Results: There were statistically significant differences in the alveolar bone height of the palatal side of maxillary anterior teeth, the labial side of maxillary lateral incisors and canine among three time points (P<0.05). The height difference of palatal alveolar bone of anterior teeth in T1-T2 stage was statistically significant (P<0.05). Palatal alveolar bone of upper and lower central incisors decreased by (1.52±0.32) and (4.96±0.46) mm, respectively. The height difference of anterior palatal alveolar bone was statistically significant in T2-T3 stage(P<0.05), the palatal alveolar bone height of central incisors increased by (1.20±0.27) and (3.14±0.35) mm respectively. The height difference of palatal alveolar bone in the anterior teeth of T1-T3 stage was statistically significant (P<0.05), and the height of palatal alveolar bone of central incisors was decreased (0.33±0.11) and (1.82±0.39) mm, respectively. There were statistically significant differences in the thickness of the cervical and middle root alveolar bone of anterior teeth among three time points (P<0.05). The difference of alveolar bone thickness of the cervical and middle root of anterior teeth at T1-T2 was statistically significant (P<0.05). decreased by (0.63±0.10) and (0.67±0.09) mm in lateral incisors, respectively. In the T2-T3 stage, the alveolar bone thickness of the crest area of the lower anterior teeth was significantly different (P<0.05), the alveolar bone thickness of mandibular central incisor crest area increased (0.09±0.03) mm. There were statistically significant differences in alveolar bone thickness in crest area and middle root of the incisors during T1-T3 stage (P<0.05), among which the middle root decreased by (0.38±0.16) mm and (0.63±0.13) mm, respectively. There was no statistically significant difference in other areas (P>0.05). The change of alveolar bone height in palatal side of upper anterior teeth at T2-T3 was very strongly negatively correlated with the change in T1-T2. The change of alveolar bone height in labial side of upper anterior teeth and lingual side of lower anterior teeth and the thickness of incisor root and neck were moderately strongly negatively correlated (r≤-0.8, P<0.001), the change of alveolar bone height in labial side of upper anterior teeth and lingual side of lower anterior teeth and the thickness of incisor crest area were moderately strongly negatively correlated (-0.8<r≤-0.4, P<0.05). Conclusions: For adult patients after retraction, anterior alveolar bone decreased significantly. In the retention stage, the same degree of bone apposition will occur, but still have alveolar bone loss compared with pre-treatment. The amount of alveolar bone change in the retention stage correlated with the amount of alveolar bone change in the treatment stage.

ABSTRACT

The rearranged during transfection (RET) is a receptor protein tyrosine kinase. Oncogenic RET fusions or mutations are found most often in non-small cell lung cancer (NSCLC) and in thyroid cancer, but also increasingly in various types of cancers at low rates. In the last few years, two potent and selective RET protein tyrosine kinase inhibitors (TKIs), pralsetinib (BLU-667) and selpercatinib (LOXO-292, LY3527723) were developed and received regulatory approval. Although pralsetinib and selpercatinib gave high overall response rates (ORRs), < 10% of patients achieved a complete response (CR). The RET TKI-tolerated residual tumors inevitably develop resistance by secondary target mutations, acquired alternative oncogenes, or MET amplification. RET G810 mutations located at the kinase solvent front site were identified as the major on-target mechanism of acquired resistance to both selpercatinib and pralsetinib. Several next-generation of RET TKIs capable of inhibiting the selpercatinib/pralsetinib-resistant RET mutants have progressed to clinical trials. However, it is likely that new TKI-adapted RET mutations will emerge to cause resistance to these next-generation of RET TKIs. Solving the problem requires a better understanding of the multiple mechanisms that support the RET TKI-tolerated persisters to identify a converging point of vulnerability to devise an effective co-treatment to eliminate the residual tumors.

ABSTRACT

【Objective】 To explore the psychological experience of blood donors with blood donation-related vasovagal reaction (DRVR), so as to provide basis for improving the quality of blood donation services. 【Methods】 The real experience of 9 DRVR blood donors was analyzed using the phenomenological research method in qualitative research. 【Results】 The occurrence of DRVR caused distinct psychological conflict among blood donor. Blood donors lacked knowledge about blood donation and expected professional evaluation and continuous support. The occurrence of DRVR was an important reason for blood donor lapsing. 【Conclusion】 By resolving the distinct psychological conflicts of DRVR blood donors, establishing DRVR early warning evaluation and feedback system, as well as strengthening the construction of support system, blood collection and supply institutions can create a good humanistic and social environment for sustainable development of voluntary blood donation.

ABSTRACT

Recurrent genital herpes is a sexually transmitted disease induced by herpes simplex virus(HSV), mainly manifested as erythema, papules, vesicles, erosion, and exudation on the skin and mucosal membranes of the genital and anal area, accompanied by burning pain, or tingling. Factors leading to its recurrence are overworking, fever, alcohol consumption, infection, sexual activity, etc. At least 1 in 10 of the 15-49-year-old population are infected with herpes simplex virus-2. There is currently no available method to completely remove the herpes simplex virus and prevent its recurrence, and recurrence seriously affects the quality of life and psychological health of patients. According to the theory of traditional Chinese medicine (TCM), the recurrence of genital herpes is mostly related to wind, dampness, heat, yin deficiency of liver and kidney, internal injuries due to emotional disorder, and dietary preference. TCM has advantages in reducing its recurrence rate. The lower energizer is closely related to skin diseases, and "lower energizer resembles drainage". Thus, the lower energizer is closely related to water and damp metabolism. Recurrent genital herpes occurs in the lower energizer and belongs to lower energizer diseases, and the fluid metabolism and qi movement in lower energizer are closely related to the occurrence of the disease. Based on thought of "lower energizer resembling drainage" and the clinical characteristics of recurrent genital herpes, this paper considered malfunction of lower energizer as its pathogenesis. Thus, smoothing the lower energizer according to the prevailing circumstances is particularly important and the treatment principle should be dispersing the pathogen from lower energizer without damaging yin. Zhulingtang (Treatise on Cold Damage and Miscellaneous Diseases) cures the difficulty in urination and thirst with desire to drink by smoothing the lower energizer. Thus, Zhulingtang was selected to treat recurrent genital herpes. This study is expected to provide a new idea for its clinical diagnosis and treatment.

ABSTRACT

Objective: To determine the knowledge of influenza, pneumonia, herpes zoster and related vaccines, willingness to vaccinate under multiple payment scenarios, and corresponding risk factors among people over 50 years old in Minhang District of Shanghai. Methods: A total of 1 672 respondents aged 50-69 from 13 communities/towns in Minhang district of Shanghai were included in this study using a stratified random sampling strategy on December 2020. The knowledge of influenza, pneumonia, herpes zoster and vaccines was investigated using a questionnaire, and the differences in the willingness under multiple payment scenarios were determined using chi-square test. The consistency in the willingness under multiple payment scenarios was compared using Cohen's Kappa and the risk factors of the willingness was determined using ordinal logistic regression. Results: The average age of 1 672 respondents was (60.48±5.96) years old, including 777 (46.47%) males and 895 (53.53%) females. A total of 1 350 subjects (80.74%) had local household registration in Shanghai. The proportion of the willingness to vaccinate for themselves, spouses, and parents under any payment scenario was determined to be 80.6% (influenza vaccine), 81.5% (pneumonia vaccine), and 74.0% (herpes zoster vaccine). The willingness to vaccinate against influenza and pneumonia under multiple payment scenarios remained stable (Kappa value ≥0.6), while that against herpes zoster infection was inconsistent (Kappa value ≤0.35). Logistic regression analysis showed that respondents who had higher knowledge of influenza and influenza vaccine [OR (95%CI): 1.111 (1.054-1.170), 1.182 (1.126-1.240), respectively], aged 50-59 [1.305 (1.085-1.531)] and local household registration in Shanghai [1.372 (1.079-1.721)] had higher willingness to vaccinate against influenza, while males had lower willingness [0.733 (0.551-0.910)]. Respondents who had higher knowledge of pneumonia and pneumonia vaccine [OR (95%CI): 1.837 (1.152-2.517), 2.217 (1.541-2.893), respectively] had higher willingness to receive pneumonia vaccine. Respondents aged 50-59 [1.327 (1.059-1.537)] and with local household registration in Shanghai [2.497 (1.417-4.400)] were more likely to be vaccinated against herpes zoster, while those with middle school degree or below [0.664 (0.396-0.992)] and high school degree [0.559 (0.324-0.964)] were less likely to be vaccinated. Conclusion: Among people aged over 50 years old in Minhang district of Shanghai, the willingness to vaccinate for themselves, spouses, and parents against influenza, pneumonia and herpes zoster infection is quite different under multiple payment scenarios, especially for herpes zoster vaccine.

ABSTRACT

Chemical fractionation of the n-BuOH partition, which was generated from the EtOH extract of the flower buds of Tussilago farfara, afforded a series of polar constituents including four new sesquiterpenoids (1-4), one new sesquiterpenoid glucoside (5) and one known analogue (6) of the eudesmane type, as well as five known quinic acid derivatives (7-11). Structures of the new compounds were unambiguously characterized by detailed spectroscopic analyses, with their absolute configurations being established by X-ray crystallography, electronic circular dichroism (ECD) calculation and induced ECD experiments. The inhibitory effect of all the isolates against LPS-induced NO production in murine RAW264.7 macrophages was evaluated, with isochlorogenic acid A (7) showing significant inhibitory activity.

ABSTRACT

Objective: To observe the clinical efficacy of sinew-bone balancing manipulation in treating lumbar disc herniation (LDH) and offer clinical evidence to support the concept of paying equal attention to sinew and bone. Methods: Sixty LDH patients were randomized into an observation group and a control group, with 30 cases in each group. The observation group was treated with the sinew-bone balancing manipulation, and the control group received conventional Tuina (Chinese therapeutic massage) manipulation. The clinical efficacy and posterior muscle chain tone effect were compared between the two groups by observing the visual analog scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and posture-associated indicators. Results: The total effective rate was 86.7% in the observation group, higher than 76.7% in the control group, but the between-group difference in efficacy was statistically insignificant (P>0.05). After treatment, the VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry showed significant changes in both groups (P<0.05). The VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry in the observation group were significantly different from those in the control group after treatment (P<0.05), but the between-group difference in the general posture symmetry was statistically insignificant (P>0.05). Conclusion: Both the sinew-bone balancing and conventional Tuina manipulations can reduce pain in LDH patients, improve lumbar function, and adjust the angle-dependent muscle tone coefficient of the posterior muscle chain and lumbar posture symmetry; except for the general posture symmetry of the posterior muscle chain, the sinew-bone balancing manipulation wins out over the conventional Tuina manipulation.

ABSTRACT

Objective:To investigate the characteristics of bacterial community in upper gastrointestinal tumors.Methods:The study population was patients with upper gastrointestinal tumors (esophageal cancer and gastric cancer). Gastroscopy was performed on the enrolled patients ( n=17), and the specimens were taken from the tumor sites. At the same time, non-tumor tissues more than 4 cm away from the tumor tissues were taken as the control. After total DNA was extracted and purified, high-throughput 16S DNA gene sequencing was used to detect the microbiota in tumor tissues and control tissues. Bioinformatics analysis was carried out and the differences between groups were compared. Results:16S DNA PCR showed that there was no significant difference in bacterial load between tumor tissues and control tissues. The α-diversity and β-diversity indexes showed that the community composition of the two groups was similar; the samples were discrete and the colony composition was different, but there was no significant difference between the two groups. The results of Venn diagram showed that there were more operational taxonomic units (OTUs) in non-tumor tissues than in tumor tissues (2 068 vs 1 358), indicating that the bacterial species in normal tissues were more abundant than those in tumor tissues. Compared with the control tissues, the percentages of Prevotellaceae ( Prevotella), Lactobacaceae ( Lactobacillus) and Fusobacteriaceae ( Fusobacterium) in tumor tissues were relatively higher (the average percentage was more than twice that of the control). Further paired comparison of the top ten bacteria in the family and genus abundance of the two groups of samples showed that Pseudomonas decreased significantly in tumor tissues at the family ( P=0.041) and genus ( P=0.041) levels, while Prevotella was significantly enriched in tumor tissues at the family ( P=0.031) and genus ( P=0.007) levels. Conclusions:The bacterial community in the tumor microenvironment of the upper gastrointestinal tumor changed, and the species enriched in the tumor site were mainly oral common anaerobic bacteria, such as Prevotellaceae ( Prevotella), Lactobacaceae ( Lactobacillus) and Fusobacteriaceae ( Fusobacterium), especially Prevotellaceae ( Prevotella).

ABSTRACT

BACKGROUND@#Exposure to the ionizing radiation (IR) encountered outside the magnetic field of the Earth poses a persistent threat to the reproductive functions of astronauts. The potential effects of space IR on the circadian rhythms of male reproductive functions have not been well characterized so far.@*METHODS@#Here, we investigated the circadian effects of IR exposure (3 Gy X-rays) on reproductive functional markers in mouse testicular tissue and epididymis at regular intervals over a 24-h day. For each animal, epididymis was tested for sperm motility, and the testis tissue was used for daily sperm production (DSP), testosterone levels, and activities of testicular enzymes (glucose-6-phosphate dehydrogenase (G6PDH), sorbitol dehydrogenase (SDH), lactic dehydrogenase (LDH), and acid phosphatase (ACP)), and the clock genes mRNA expression such as Clock, Bmal1, Ror-α, Ror-β, or Ror-γ.@*RESULTS@#Mice exposed to IR exhibited a disruption in circadian rhythms of reproductive markers, as indicated by decreased sperm motility, increased daily sperm production (DSP), and reduced activities of testis enzymes such as G6PDH, SDH, LDH, and ACP. Moreover, IR exposure also decreased mRNA expression of five clock genes (Clock, Bmal1, Ror-α, Ror-β, or Ror-γ) in testis, with alteration in the rhythm parameters.@*CONCLUSION@#These findings suggested potential health effects of IR exposure on reproductive functions of male astronauts, in terms of both the daily overall level as well as the circadian rhythmicity.

ABSTRACT

Objective@#To assess the outcomes and toxic effects of 5-day actinomycin D (Act-D) salvage therapy and to explore the predictors of Act-D resistance in patients with low-risk gestational trophoblastic neoplasia (GTN)who failed 5-day methotrexate (MTX) chemotherapy. @*Methods@#This retrospective study analyzed patients with low-risk GTN administered Act-D salvage therapy after failing MTX chemotherapy at Women's Hospital, School of Medicine Zhejiang University between January 2000 and December 2015. The clinical parameters of these patients were collected and analyzed. @*Results@#The final analysis included 89 cases. Of these, 73 cases (82.02%) responded to salvage Act-D. The remaining 16 resistant cases were switched to etoposide, MTX, Act-D/ cyclophosphamide, and vincristine chemotherapy and achieved complete remission. Serum human chorionic gonadotrophin levels before Act-D salvage therapy (hCG Act-D )in the Act-Dresistant cases were significantly higher than those in the Act-D responders (median 605 vs.103 IU/L, p=0.009). However, the range of hCGAct-D values in Act-D responders was wider than that in Act-D-resistant cases (5.76–16,664 IU/L vs. 11.43–6,732 IU/L). Thus, assigning a general cut-off value was difficult considering the individual setting. Except for 2 cases requiring other salvage regimens due to Act-D toxicity, 97.80% of cases (89/91) tolerated the toxicity. During at least 1-year follow-up, the survival rate was 100.00% and no case developed recurrence. @*Conclusion@#Based on the good therapeutic effect and tolerable toxicity, we recommend Act-D salvage therapy for all patients with low-risk GTN who fail primary MTX chemotherapy.The higher serum hCG levels before Act-D salvage therapy may be associated with resistance to this treatment.

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy of vertebral body stent (VBS) system and percutanous kyphoplasty (PKP) combined with zoledronic acid for the treatment of severely osteoporotic compression vertebral fractures (OVCFs).@*METHODS@#The clinical data of 48 patients with osteoporotic thoracolumbar fractures treated from December 2017 to December 2018 were retrospectively analyzed, including 13 males and 35 females, aged 55 to 92 years old with an average (71.2±10.5) years. All patients were treated with VBS system PKP surgery, and zoledronic acid injection was used for anti-osteoporosis treatment after operation. The VAS scores ODI, the height of diseasedvertebral lost were compared before operation, 3 d and half a year after operation, and whether there was re-fracture of diseased or adjacent vertevrae after operation was observed.@*RESULTS@#Before operation, 3 d and half a year after operation, VAS scores were 7.60±0.12, 3.00±0.46, 1.20±0.23, ODI were(82.00±0.32)%, (30.00±1.50) %, (18.00±0.16) %, the height of diseased vertebral lost were (12.00±0.43) mm, (3.00± 0.15) mm, (3.60±0.51) mm respectively. Postoperative VAS score, ODI, the height of diseased vertebral lost were obviously improved (0.05). All the 48 patients were followed up with an average time of (6.6±0.5) months. All the incisions healed at grade A after operation, and no re-fracture of diseased vertebrae or adjacent vertebrae was found at the final follow-up.@*CONCLUSION@#VBS system and PKP combined with zoledronic acid in the treatment of OVCFs not only may effectively relieve the pain in the thoracolumbar back, improve the mobility of the thoracolumbar, but also can restore the height of the vertebral body to the maximum extent, and prevent the re-fracture of the affected vertebrae and adjacent vertebrae, which is worthy to spread in clinic.

ABSTRACT

Objective: To investigate the effects of ticagrelor on cardiorespiratory fitness in patients with coronary heart disease after percutaneous coronary intervention (PCI). Methods: A total of 1 073 patients, who were diagnosed as coronary heart disease and underwent cardiopulmonary exercise testing (CPET) within 1 year after PCI, were enrolled from September 2017 to September 2019 in Peking University Third Hospital, including 309 patients in ticagrelor group and 764 patients in clopidogrel group. Clinical information, blood test results, echocardiographic parameters, cardiorespiratory fitness related parameters (including peak oxygen uptake (VO(2)), anaerobic threshold VO(2), peak oxygen pulse (VO(2)/HR) and carbon dioxide ventilation equivalent (VE/VCO(2)) slope), coronary lesions and intervention information were obtained. Cardiopulmonary fitness related indexes were compared between the two groups, and the correlation between ticagrelor use and cardiopulmonary fitness related indexes was analyzed by multivariate logistic regression. Patients who underwent CPET within 1 month after PCI were included in the subgroup analysis. Results: In ticagrelor group, the age was (60.3±10.3) years, and 253(81.9%) cases were male. The age of clopidogrel group was (60.6±10.0) years, and there were 608(79.6%) males. No significant differences were observed in peak VO(2), anaerobic threshold VO(2), and peak VO(2)/HR between the two groups (all P>0.05), but the VE/VCO(2) slope was significantly higher in the ticagrelor group than in the clopidogrel group (30.075 (27.207, 33.603) vs. 28.853 (25.970, 32.336), P<0.001). Logistic regression analysis suggested that the peak VO(2), anaerobic threshold VO(2) and peak VO(2)/HR were not significantly correlated with the ticagrelor use (all P>0.05), while the VE/VCO(2) slope was independently correlated with ticagrelor use (OR=1.098, 95%CI 1.032-1.168, P=0.003). Subgroup analysis of patients who underwent CPET within 1 month after PCI also indicated that no significant difference were observed in peak VO(2), anaerobic threshold VO(2), peak VO(2)/HR and VE/VCO(2) slope between the two groups (all P>0.05). Logistic regression analysis suggested that the peak VO(2), anaerobic threshold VO(2) and peak VO(2)/HR were not significantly correlated with ticagrelor use (all P>0.05), while the VE/VCO(2) slope was significantly correlated with ticagrelor use (OR=1.132, 95%CI 1.030-1.244, P=0.010). Conclusion: Among coronary heart disease patients after PCI, treatment with clopidogrel does not result in significant decrease in exercise endurance as compared with patients treated with ticagrelor.

ABSTRACT

Objective:To identify objective markers between the Parkinson variant of multiple system atrophy (MSA-P) and Parkinson′s disease (PD).Methods:Retrospective analysis was performed on 10 patients with MSA-P, 15 patients with PD, and 15 healthy control group during the period from August 2016 to February 2019 in Baoshan Branch of Shanghai First People′s Hospital.We combined the novel tract based spatial statistics (TBSS) and region of interest (ROI) analyses for the first time to investigate three groups with diffusion tensor imaging. By TBSS, we performed pairwise comparisons of mean diffusivity and fractional anisotropy (FA) maps. The clusters with significant differences between MSA-P and PD were used as ROIs for further analyses.Results:FA values in the left anterior thalamic radiation(ATR) (ROI values were 0.371(0.287-0.535), 0.472(0.390-0.594), 0.473(0.388-0.555); P values were 0.008, 0.008) and left superior longitudinal fasciculus (SLF)(ROI values were 0.397(0.291-0.469), 0.456(0.338-0.560), 0.473(0.427-0.530); P values were 0.013,<0.001) were significantly decreased in MSA-P compared with PD or controls, and significantly correlated with clinical data(( r =-0.807, P =0.005),( r =-0.455, P =0.022)). Conclusion:Our findings indicate the abnormalities of left ATR and left SLF as specific biomarkers for differential diagnosis.

ABSTRACT

TSCI have dyskinesia and sensory disturbance that can cause various life-threaten complications. The patients with traumatic spinal cord injury (TSCI), seriously affecting the quality of life of patients. Based on the epidemiology of TSCI and domestic and foreign literatures as well as expert investigations, this expert consensus reviews the definition, injury classification, rehabilitation assessment, rehabilitation strategies and rehabilitation measures of TSCI so as to provide early standardized rehabilitation treatment methods for TSCI.
