ABSTRACT
ObjectiveTaking Achyranthis Bidentatae Radix（ABR） from different origins as samples， to quantitatively analyze the chemical composition and chromaticity of ABR with different processing degrees， and clarify the correlation and change law between color and composition in the processing process of ABR， so as to provide reference for the quality evaluation of processed products of ABR. MethodThe colorimeter is used to measure the chromaticity values of three kinds of processing degrees of ABR in different origins to show the color value change trend during the processing process， and the color parameters of wine-processed and salt-processed products of ABR with different processing degrees were analyzed by principal component analysis（PCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA） and other analysis methods. The contents of eight representative components of ABR were measured by high performance liquid chromatography（HPLC）， the correlation between chromaticity and each representative component was analyzed by Pearson correlation analysis， and the applicability of the selected eight representative components was further verified by Fisher linear discriminant analysis， and the wine-processed and salt-processed products of ABR with different processing degrees were grouped according to the degree of processing， and 48 samples of wine-processed and salt-processed products with different processing degrees were used as training samples. Taking the contents of 5-hydroxymethylfurfural， polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone， ginsenoside Ro， chikusetsusaponin Ⅳa and polysaccharides as variables， the discriminant function was established respectively， and 12 samples of wine-processed and salt-processed products of ABR with different processing degrees were back-tested to verify the discriminant function and test the reliability of the function. ResultPCA and OPLS-DA results showed that ABR samples with different processing degrees were classified into clusters， and the results could significantly distinguish different processed products. During the process of wine and salt processing， the contents of 5-hydroxymethylfurfural， ginsenoside Ro， and chikusetsusaponin Ⅳa gradually increased with the deepening of the processing degree， while the contents of polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone and polysaccharides showed a gradual decreasing trend， indicating these 8 components increased and decreased to different degrees in the process of wine and salt processing. The results of Pearson correlation analysis showed that the 5-hydroxymethylfurfural content of the samples with different processing degrees of wine-processed and salt-processed products were negatively correlated with the brightness value（L*） and the total color difference value（E*ab）（P<0.01）， and positively correlated with the red-green value（a*） and the yellow-blue value（b*）（P<0.01）， and that the content of polypodine B and polysaccharides were positively correlated with L* and E*ab（P<0.01）. The discriminant functions of wine-processed and salt-processed products of ABR were established by Fisher linear discriminant analysis， and their accuracy rates in the training samples were 93.75% and 95.83%， respectively. Twelve test samples of wine-processed and salt-processed products with different processing degree were back substitution， and the correct rate was 100%. ConclusionThe trend of composition and color changes of ABR with different processing degrees in different production areas is relatively consistent， and the color value can better distinguish ABR with different processing degrees， and the color of ABR is related to some representative components in the processing process， indicating that the color can provide reference for the identification of the processing degree of ABR and the prediction of component content.
ABSTRACT
ObjectiveTo observe the microbial changes in Wistar rats with liver injury caused by the Dictamni Cortex-Flavescens Sophora by high-throughput sequencing technology and investigate the potential mechanism of liver injury caused by the Dictamni Cortex-Flavescens Sophora. MethodFemale Wistar rats were randomly divided into four groups： normal group， as well as low-dose， medium-dose， and high-dose groups of traditional Chinese medicine （TCM）. The rats were gavaged with the Dictamni Cortex-Flavescens Sophora in different doses （4.125， 8.25， 16.5 g·kg-1 of raw drug respectively） for 28 days， and the general condition was recorded. The liver-body weight ratio was calculated， and the biochemical indexes of serum were observed. The Hematoxylin-eosin （HE） staining was used to observe pathological changes in the liver， and 16S rDNA high-throughput sequencing was utilized to detect fecal microbial changes in rats. ResultCompared with the normal group， Dictamni Cortex-Flavescens Sophora increased the liver weights and liver-body weight ratios of Wistar rats. The difference in liver weight between the medium-dose and high-dose groups of TCM was statistically significant （P<0.05）， and the liver-body weight ratios of the low-dose， medium-dose， and high-dose groups of TCM were all statistically significant （P<0.05）. Compared with the normal group， serum albumin and cholesterol levels increased in the medium-dose and high-dose groups of TCM （P<0.05）. The histopathology of the liver in the medium-dose and high-dose groups of TCM showed tiny vacuole-like changes. Compared with the normal group， there were obvious intestinal flora disorders after administration of Dictamni Cortex-Flavescens Sophora， and alpha diversity increased in the medium-dose and high-dose groups of TCM. The principal coordinates analysis showed that species increasingly deviated from the normal group as the administered dose increased. Compared with the normal group， the proportion of Firmicutes and Bacteroidota decreased after the drug administration， and the genus level of Parasutterella， Romboutsia， Turicibacter， Allobaculum， and Dubosiella increased. The genus level of Lachnospiraceae_NK4A136_group， Blautia， Erysipelatoclostridium， Muribaculum， and Ruminococcus_gnavus_group decreased. The correlation analysis showed that Parasutterella， Romboutsia， Turicibacter， Allobaculum， and Dubosiella were positively correlated with serum cholesterol and liver-body weight ratio， and lanchnospiraceae_NK4A136_group， Blautia， Muribaculum， Erysipelatoclostridium， and Ruminococcus_gnavus_group were negatively associated with serum cholesterol and liver-body weight ratio. ConclusionThe liver injury caused by Dictamni Cortex-Flavescens Sophora is manifested as a lipid metabolism disorder， and the mechanism is related to the increase in lipid metabolism-related microorganisms.
ABSTRACT
Objective To explore the correlation between hospitalization for severe asthma and climate change among adult residents in Dalian. Methods Clinical data of asthma inpatients in Dalian First Affiliated Hospital from January to December 2022 were collected, and assigned into severe asthma group and non-severe asthma group according to the diagnostic criteria of severe asthma. Spirometer was used for the measurement of (forced expiratory volume in the first second , FEV1) and (forced vital capacity , FVC), and the serum white blood cell count and C-reactive protein level were measured by biochemical analyzer. Meantime, meteorological parameters including monthly average temperature, relative humidity, wind speed and duration of sunshine hours were also collected. Then Spearman correlation analysis was conducted to discuss the correlation between the number of hospitalizations for severe asthma and meteorological parameters. Of the 260 asthma patients, 153 had severe asthma and 107 had non-severe asthma. There were 85 male and 68 female patients with severe asthma. The onset age distribution of severe asthma was concentrated at 60-79 years old, with 94 cases, followed by 50-59 years old (n=26). The peak time of onset in each year was from March to May, with 14, 19 and 16 cases, respectively. The secondary peak was from November to January, with 15, 18 and 13 cases, and there were fewer hospital admissions from June to October. FEV1 and FEV1/FVC values were smaller in severe asthma group than in non-severe asthma group, while the white blood cell count and C-reactive protein levels were higher than those in non severe asthma group (P0.05), but was negatively correlated with average temperature and humidity (P<0.05). Conclusion The number of hospital admissions for severe asthma in Dalian varies with the seasons, therefore, early and active interventions are of great value in preventing severe asthma in months with high variations in temperature and humidity.
ABSTRACT
@#Abstract: To investigate the in vitro release, in vivo pharmacokinetics, and the in vitro-in vivo correlation of progesterone suspension injection, self-made progesterone suspension injection was taken as an example. The in vitro release curves of three different particle sizes of progesterone suspension injections were measured using paddle method and dialysis bag method. The in vivo pharmacokinetic characteristics of self-made progesterone suspension injection was studied on SD rats. The plasma concentration of self-made progesterone preparation was detected after intramuscular injection, and correlated with the in vitro release profiles obtained by the dialysis bag method after processing by Wagner-Nelson method. The results showed that when the in vitro release of three different particle sizes of progesterone suspension injections was measured by the paddle method, more than 85% was rapidly released within 20 min, while 85% cumulative release was reached at 40 h, 84 h and 120 h by dialysis bag method, respectively. The release rate obtained by the dialysis bag method was basically consistent with the in vivo release trend, with a correlation coefficient of >0.95, indicating a strong in vivo and in vitro correlation. This study provides some reference for the establishment of the in vitro and in vivo correlation of long-acting suspension injection.

ABSTRACT
Objective To explore the value of the Physiology and Surgical Severity Score(POSSUM)scoring system in predicting postoperative complications in elderly patients with thoracic surgery,and to ana-lyze its correlation with Clavien-Dindo classification.Methods The data of 182 elderly patients who under-went thoracic surgery in this hospital from October 2019 to March 2023 were retrospectively analyzed.They were divided into the complication group and the non-complication group according to whether there were complications after surgery.The baseline data and POSSUM score of the two groups were analyzed,and the receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of POSSUM for post-operative complications in elderly patients.POSSUM of patients with different Clavien-Dindo classification was compared,and the correlation between POSSUM and Clavien-Dindo classification analyzed.Results The incidence of pulmonary infection was the highest in the complication group,followed by hypoproteinemia.POSSUM in the complication group was higher than that in non-complication group before operation,and the difference was statistically significant(P＜0.05).The ROC curve showed that the area under curve(AUC)value of POSSUM was 0.829;In the complication group,according to Clavien-Dindo classification,there were 5 cases of grade Ⅰ,47 cases of grade Ⅱ,8 cases of grade Ⅱ Ⅲ,7 cases of grade Ⅳ and 8 cases of grade V,the difference was statistically significant(P＜0.05).The correlation analysis showed that POSSUM score was positively correlated with Clavien-Dindo classification(r＞0.513,P＜0.05).Conclusion The POSSUM scoring system has a high value in predicting postoperative complications in elderly patients with thoracic surgery.
ABSTRACT
Objective To study the traditional Chinese medicine(TCM)constitution characteristics of overweight/obese patients in Shanghai region and to investigate the correlation of TCM constitution with body composition.Methods Relevant data were collected from the patients with complete information of TCM constitution and human body composition analysis who visited the specialized outpatient clinic of acup-moxibustion catgut embedding therapy in the Department of Endocrinology,Shanghai Tenth People's Hospital from August 2020 to December 2022.The patients were divided into a normal body mass group(BMI＜24 kg/m2),an overweight group(24 kg/m2≤BMI＜28 kg/m2)and obesity group(BMI≥28 kg/m2),and then the distribution of TCM constitution types in the three groups of patients were analyzed.After that,the correlation between TCM constitution and body composition were explored with multiple regression analysis.Results(1)A total of 315 patients were included,of which 43 patients had normal body mass,85 patients were overweight and 187 patients were obese.(2)The TCM constitution types in descending order of the composition ratio in the normal body mass group and in the overweight group were spleen deficiency constitution,liver stagnation constitution,damp-heat constitution,yang deficiency constitution,and yin deficiency constitution,in the obese group were spleen deficiency constitution,yang deficiency constitution,damp-heat constitution,liver stagnation constitution,and yin deficiency constitution,and in the overweight/obese group were spleen deficiency constitution,damp-heat constitution,yang deficiency constitution,liver stagnation constitution,and yin deficiency constitution.No statistically significant differences of the distribution of TCM constitution types were shown between normal body bass population and overweight/obese population(P＞0.05).In both normal body mass population and overweight/obese population,the single body constitution type was common,and biased constitution was rare,and there was no statistically significant difference when comparing between the two groups(P＞0.05).(3)The results of multiple regression analysis showed that the basal metabolism of all patients was positively correlated with yang deficiency constitution and was negatively correlated with damp-heat constitution,and the differences were statistically significant(P＜0.01).It is indicated that if the score of yang deficiency constitution rose by one point,the basal metabolism would increase by 0.54 kcal,and if the score of damp-heat constitution decreased by one point,the basal metabolism would decrease by 1.005 kcal.Conclusion In Shanghai region,obesity may be the main indication of the variation of the body constitution.In addition to spleen deficiency constitution,the proportions of yang deficiency constitution,damp-heat constitution and liver stagnation constitution are also higher in obese patients.In terms of the correlation between TCM constitution and body composition,basal metabolism is positively correlated with yang deficiency constitution and is negatively correlated with damp-heat constitution.Therefore,for the patients with yang deficiency constitution and damp-heat constitution,the influence of the basal metabolism level on the development of the disease should be taken into account.
ABSTRACT
This article takes pectoral qi as the starting point to discuss the traditional Chinese medicine(TCM)pathogenesis as well as the diagnostic and therapeutic approach to difficult withdrawal of mechanical ventilation in mechanically ventilated patients.According to the five-viscera correlation theory,it is believed that the onset of difficult withdrawal of mechanical ventilation is closely related to pectoral qi.The core pathogenesis of difficult withdrawal of mechanical ventilation is due to the insufficiency of pectoral qi and the deficiency of the lung,spleen and kidney,and the obstruction of pectoral qi and disharmony of qi and blood contribute to the key pathogenesis.Chinese medicine treatment can be carried out by the usage of Sijunzi Tang(Four Mild-Drug Decoction),Bufei Tang(Decoction for Replenishing Lung),Shenling Baizhu San(Powder of Radix Ginseng,Poria and Rhizoma Atractylodis Macrocephalae)to supplement and benefit pectoral qi,and by the utilization of Buzhong Yiqi Tang(Decoction for Tonifying Middle Energizer and Replenishing Qi),Shengxian Tang(Decoction for Lifting the Sinking of Qi in Chest),Juyuan Jian(Decoction for Replenishing Qi and Lifting the Sunken Qi)to elevate yang and lift the sinking of Qi.Moreover,herbs for regulating qi and blood should be added,and the management of the diet and daily living based on the identification of the deficiency and excess of the five viscera is stressed,so as to enhance the success rate of withdrawal of mechanical ventilation.The exploration will provide ideas for the treatment of difficult withdrawal of mechanical ventilation with the integrated Chinese and western medicine.

ABSTRACT
Objective:To explore the relationship between risk perception and health promoting lifestyle profile in population with cardiovascular disease (CVD), and construct a prediction model for clinical screening and targeted intervention.Methods:A cross-sectional survey method was used to select 272 people at moderate and high risk of CVD from the Second Affiliated Hospital of Zhejiang University School of Medicine from March to August 2022. The general information questionnaire, Chinese version of Attitude and Beliefs about Cardiovascular Disease Knowledge and Risk Questionnaire (ABCD-C), and Health Promoting Lifestyle Profile-II (HPLP Ⅱ) were used. Based on multiple regression analysis, a nomogram model for health promoting lifestyle in high-risk CVD population was constructed.Results:Among 272 participants, male 150 cases, female 122 cases, aged (60.58 ± 10.64) years old. The total ABCD-C score was (56.57 ± 5.69), and the total HPLP Ⅱ score was (111.92 ± 12.47). ABCD-C score was significantly positively correlated with HPLP Ⅱ score ( r=0.556, P<0.01). The median of HPLP Ⅱ total score (111 points) was used as the cut-off point for low level of health-promoting lifestyle (≤111 points) and high level of health-promoting lifestyle (>111 points), and used it as the dependent variable, smoking ( OR=0.215, 95% CI 0.104-0.446) was a barrier factor for participants to adopt healthy lifestyle; being married ( OR=14.237, 95% CI 1.963-103.238), having a family average monthly income higher than 5 000 yuan ( OR=4.101, 95% CI 1.369-12.288), higher score of CVD prevention knowledge ( OR=1.660, 95% CI 1.373-2.007), perceived benefits and intention to change physical activity ( OR=1.445, 95% CI 1.255-1.663), perceived benefits and intention to change healthy diet ( OR=1.322, 95% CI 1.058-1.654) were promoting factors. Conclusions:The health-promoting lifestyle of populations at risk for CVD is above-average, influenced by factors such as smoking, marital and economic status, risk attitudes, and beliefs. Utilizing the nomogram model for early screening and targeted risk communication among key populations may contribute to improving their health behavior.
ABSTRACT
BACKGROUND:MicroRNA(miRNA)levels are closely related to cell apoptosis and proliferation,extracellular matrix metabolism and inflammatory response in intervertebral disc cells.However,the specific role of miR-142-3p in lumbar intervertebral disc degeneration remains unclear. OBJECTIVE:To investigate the correlation between the expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in nucleus pulposus tissue and degree of human lumbar intervertebral disc degeneration. METHODS:A total of 82 patients with lumbar intervertebral disc degenerative diseases in Suzhou Ninth People's Hospital from January 2020 to March 2022 were collected as the study subjects,all of whom underwent MRI examination before operation.According to the Videman classification,the patients were divided into mild degeneration group(n=36),moderate degeneration group(n=26)and severe degeneration group(n=20).Eighty-two specimens of the nucleus pulposus were obtained.The mRNA expression of miRNA-142-3p as well as the mRNA and protein expression of mixed lineage kinase 3,interleukin-1β,type I collagen,type II collagen in nucleus pulposus tissue were detected by qPCR and western blot assay.The correlation between the degree of human lumbar intervertebral disc degeneration and the expression levels of miRNA-142-3p,mixed lineage kinase 3,and interleukin-1β was also assessed using the Spearman correlation coefficient method.Thirty adult Sprague-Dawley rats were divided into sham-operated group(executed after puncturing skin and muscle only),mild degeneration group(executed 1 week after puncturing Co7/8 segments)and severe degeneration group(executed 2 weeks after puncturing Co7/8 segments),with 10 rats in each group.After that,we detected the protein expression of mixed lineage kinase 3 and interleukin-1β as well as the gene expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in the nucleus pulposus tissue. RESULTS AND CONCLUSION:In human nucleus pulposus tissue,the miRNA-142-3p expression ranked from high to low as follows:mild degeneration group>moderate degeneration group>severe degeneration group(P<0.05);the gene and protein expression of mixed lineage kinase 3 and interleukin-1β from low to high was as follows:mild degeneration group<moderate degeneration group<severe degeneration group(P<0.05);the gene and protein expression of type I collagen from low to high was as follows:mild degeneration group<moderate degeneration group<severe degeneration group(P<0.05),and the gene and protein expression of type I collagen from high to low was as follows:mild degeneration group>moderate degeneration group>severe degeneration group(P<0.05).Spearman correlation analysis showed that the degree of disc degeneration was negatively correlated with miRNA-142-3p expression(P<0.05)and positively correlated with mixed lineage kinase 3 and interleukin-1β expression(P<0.05).In rat nucleus pulposus tissue,compared with the sham-operated group,the expression of mixed lineage kinase 3 and interleukin-1β gene and protein was elevated in the mild degeneration group(P<0.05)while miRNA-142-3p expression was decreased(P<0.05);compared with the mild degeneration group,the expression of mixed lineage kinase 3 and interleukin-1β gene and protein was increased in the severe degeneration group(P<0.05)while miRNA-142-3p expression was decreased(P<0.05).To conclude,the degree of human lumbar intervertebral disc degeneration is negatively correlated with miRNA-142-3p expression and positively correlated with mixed lineage kinase 3 and interleukin-1β expression in nucleus pulposus tissue.
ABSTRACT
BACKGROUND:The distribution of horizontal pressure in adolescent idiopathic scoliosis can be used to evaluate the coronal imbalance.Currently,there are no reports on the characteristics of coronal pressure distribution and its correlation with coronal imbalance. OBJECTIVE:To explore the correlation between coronal pressure variation and coronal imbalance in adolescent idiopathic scoliosis patients. METHODS:A total of 39 adolescent idiopathic scoliosis patients who met the inclusion and exclusion criteria in Lianyungang First People's Hospital from March 2021 to June 2022 were selected as the adolescent idiopathic scoliosis group,and 30 matched healthy volunteers were recruited from the outpatient department as the control group.The horizontal position pressure,folding position pressure,coefficient of variation,and global and trunk pressure variation were measured by the TBED Postural Couch evaluation system.In the adolescent idiopathic scoliosis group,full-length spine radiographs were taken to measure Cobb angle,coronal balance,apical vertebral deviation and Nash-Moe rotation.The characteristics of coronal pressure variation and its correlation with coronal imbalance were analyzed. RESULTS AND CONCLUSION:(1)Compared with the control group,there was no statistically significant difference in the horizontal position pressure and folding position pressure in the adolescent idiopathic scoliosis group(P>0.05),but the global pressure variation and coefficient of variation were significantly increased(all P<0.05).(2)There were differences in both sides of the trunk of the adolescent idiopathic scoliosis group and the control group(P<0.05),and the convex side pressure variation in the adolescent idiopathic scoliosis group was higher than the concave side pressure variation in the left and right side pressure variation in the control group(all P<0.05).(3)The variation of the convex side pressure of the trunk in adolescent idiopathic scoliosis patients was positively correlated with coronal balance intensity(r=0.692,P<0.05),moderately positively correlated with Cobb angle and apical vertebral deviation(r=0.499,0.595,all P<0.05),and weakly correlated with Nash-Moe grade(r=0.377,P<0.05).The variation of the concave side pressure of the trunk was moderately positively correlated with coronal balance(r=0.410,P<0.05),and the rest was weakly correlated or not correlated(P>0.05).(4)These findings indicate that pressure variation may be used as an adjoint assessment tool in patients with mild to moderate scoliosis.
ABSTRACT
BACKGROUND:The risk factors for patellofemoral pain syndrome are still unclear and research on risk factors is gradually becoming a hot topic in order to improve the therapeutic outcome of this disease. OBJECTIVE:To investigate the relationship between lower limb alignment and patellofemoral pain syndrome in young male runners. METHODS:In the same running population,21 patients with bilateral knee pain,29 patients with single knee pain and 20 normal runners were collected from January 2021 to July 2022.Full-length X-ray examination of both lower limbs in standing position was performed in all subjects.The lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,hip-knee-ankle angle,and knee physical valgus angle were measured and statistically analyzed. RESULTS AND CONCLUSION:There was no significant difference in the parameters between the left and right knees in each group(P>0.05).Compared with the normal group,no significant changes in lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,and hip-knee-ankle angle were observed in the single knee pain group and double knee pain group,while the knee physical valgus angle was significantly increased in these two groups(P<0.05).To conclude,increased knee physical valgus angle may be a risk factor for patellofemoral pain syndrome.
ABSTRACT
BACKGROUND:The pathogenesis of autoimmune hepatitis has not been clearly elucidated.Circular RNA(CircRNA)is a research hotspot in the field of RNA and is involved in the pathogenesis of many autoimmune diseases.However,the role of CircRNA in autoimmune hepatitis remains unclear. OBJECTIVE:To investigate the relationship between CircRNA(CircRNA)and concanavalin A induced liver injury in mice with autoimmune hepatitis. METHODS:Bioinformatics analysis was performed on CircRNA profiles selected by previous microarray technology,including gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses,so as to explore the potential biological functions of these differentially expressed genes.Twelve C57BL/6 mice were randomized into normal group and model group(n=6 per group).Autoimmune hepatitis model was established by tail vein injection of concanavalin A in the model group.Mice were killed at 12 hours after modeling to extract mouse liver and peripheral blood.The expression levels of CircRNAs were verified by qRT-PCR.Serum alanine aminotransferase and aspartate aminotransferase levels were detected by colorimetric method.The levels of oxidative stress indexes malondialdehyde and nitric oxide in mouse liver were detected by microplate method.The correlation between oxidative stress level and liver injury index was analyzed. RESULTS AND CONCLUSION:The results of GO analysis showed that the target genes with up-regulated CircRNAs expression were mainly involved in the biological processes of SNARE complex assembly regulation(P=0.004),their molecular functions were mainly metal ion binding(P=0.000 29),and the cell components were mainly enriched in CORVET complex(P=0.075).The biological processes involved in the down-regulated circRNAs target genes were mainly"negative regulation of pancreatic secretion"(P=0.000 42),the molecular functions were mainly"transcriptional activator activity"(P=0.025),and the cell components were mainly enriched in"extracellular components"(P=0.006).KEGG results showed that the target genes with up-regulated CircRNAs expression were mainly enriched in the"base excision-repair"signaling pathways(P=0.026).Compared with the normal group,serum alanine aminotransferase and aspartate aminotransferase levels and the levels of malondialdehyde and nitric oxide in mouse liver in the model group were significantly increased(P＜0.01).Compared with the normal group,the expression of two selected CircRNAs(mmu-circ-0001520 and mmu-circ-0001577)was increased in the model group(P＜0.05).Spearman correlation analysis showed that the expression of mmu-circ-0001520 and mmu-circ-0001577 was positively correlated with alanine aminotransferase,aspartate aminotransferase,malondialdehyde and nitric oxide.To conclude,the differential expression of CircRNAs is correlated with liver injury in autoimmune hepatitis mice.mmu-circ-0001520 and mmu-circ-0001577 are expected to be diagnostic biomarkers and therapeutic targets for autoimmune hepatitis.
ABSTRACT
BACKGROUND:The Pilon fracture has a complex fracture line and a comminuted fracture fragment.It is often associated with bone loss and soft tissue damage and is one of the most difficult fractures to treat clinically. OBJECTIVE:To analyze the correlation between tibial and fibular fractures in Pilon fractures. METHODS:A retrospective analysis was conducted on 188 patients with Pilon fracture in the Department of Trauma Orthopedics,The Second People's Hospital of Lianyungang City from January 2014 to January 2022.Imaging data of these patients were collected.Fibular fracture level,fibular fracture type,number of fibular fracture blocks,tibial position status,main fracture blocks of the tibia,size of medial fracture blocks of the tibia,tibial fracture angle,Topliss classification(sagittal plane)and Topliss classification(coronal plane)were summarized into a database.SPSS 25.0 was used to analyze the data of tibia and fibula in Pilon fractures by Spearman correlation analysis.On the basis of the correlation,multiple disordered Logistic regression was used to further analyze the correlation. RESULTS AND CONCLUSION:(1)Spearman correlation analysis showed that tibial fracture angle was positively correlated with fibular fracture type,fibular fracture level and fibular fracture number.Tibial position status was positively correlated with tibial fracture angle and Topliss classification(coronal plane),but negatively correlated with major tibial fracture blocks and Topliss classification(sagittal plane).The level of fibular fracture was positively correlated with the type of fibular fracture and the number of fibular fractures.The main fracture blocks of the tibia were positively correlated with Topliss classification(coronal plane)and negatively correlated with Topliss classification(sagittal plane).(2)Multiple Logistic regression analysis showed that:the level of fibular fracture was correlated with the type of fibular fracture(P<0.05);the number of fibular fractures was correlated with the main fracture block of tibia(P<0.05).(3)It is indicated that the more inclined the ankle joint was to the valgus,the more likely it was to lead to fibular fracture,and the higher the fibular fracture level,the more serious the fibular fracture degree,the more complex the fibular fracture type,the larger the tibial fracture angle,the more the tibia presented Topliss classification(coronal plane)fracture.(4)When the ankle joint was more inclined to be in varus or varus + dorsiflexion,the fibula often did not fracture or simple fracture occurred,and the lower the fracture level,the smaller the tibial fracture angle,the more Topliss classification of the tibia(sagittal plane),the more main fracture blocks of the tibia,the larger the medial fracture block.When the ankle joint is in the dorsiflexion,it often results in a simple fibular fracture with a posterolateral tibial fracture.
ABSTRACT
BACKGROUND:Patients with degenerative cervical spondylosis often suffer from changed varicosity of the cervical spine,unbalanced neck-shoulder muscular strength,and descending power. OBJECTIVE:To probe into the correlation between sagittal curvature parameters and pain threshold for neck-shoulder muscles in degenerative cervical spondylosis. METHODS:Totally 50 patients with degenerative cervical spondylosis received treatment at the 3D Printed Outpatient Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2022 to March 2023 were included in the study.After excluding the 10 patients of cervical lateral projection that failed to meet the measurement conditions,the cervical lateral projections were shot to measure the following iconography parameters:Borden value and C2-7 Cobb angle as well as pain thresholds on the midpoint of the superior trapezius muscle in bilateral bundles and at 1 cm beside the C5-6 interspike.The correlation between sagittal curvature parameters and pain threshold of neck-shoulder muscles in degenerative cervical spondylosis was analyzed. RESULTS AND CONCLUSION:(1)The Borden value of sagittal curvature showed a moderately positive correlation with the bundle pain threshold in the left upper trapezius muscle,the bundle pain threshold in the right upper trapezius muscle,and the pain threshold at the 1 cm of the left side beside the C5-6 interspike(r=0.498,P<0.01;r=0.448,P<0.05;r=0.405,P<0.05)and a weak positive correlation with the pain threshold at the 1 cm of the right side beside the C5-6 interspike(r=0.322,P<0.05).(2)The C2-7 Cobb angle showed a weak positive correlation with the left squared myalgia threshold(r=0.355,P<0.05),and there was no correlation with the pain threshold of the left trapezius muscle and the pain threshold at the 1 cm of both sides beside the C5-6 interspike.(3)There was a correlation between the pain threshold of the neck-shoulder muscles,and a high correlation between the pain threshold of the left and right muscles and the pain threshold within the left and right side muscles,indicating that the neck-shoulder muscles are consistent and may be related to the coordination of the neck-shoulder movements.
