Resveratrol Alleviates Osteoporosis by Promoting Osteogenic Differentiation of Bone Marrow Mesenchymal Stem Cells via SITR1/PI3K/AKT Pathway / El Resveratrol Alivia la Osteoporosis al Promover la Diferenciación Osteogénica de las Células Madre Mesenquimales de la Médula Ósea a Través de la Vía SITR1/PI3K/AKT

SUMMARY: Senile osteoporosis is mainly caused by reduced osteoblast differentiation and has become the leading cause of fractures in the elderly worldwide. Natural organics are emerging as a potential option for the prevention and treatment of osteoporosis. This study was designed to study the effect of resveratrol on osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) in osteoporosis mice. A mouse model of osteoporosis was established by subcutaneous injection of dexamethasone and treated with resveratrol administered by gavage. In vivo and in vitro, we used western blot to detect protein expression, and evaluated osteogenic differentiation of BMSCs by detecting the expression of osteogenic differentiation related proteins, calcium deposition, ALP activity and osteocalcin content. Resveratrol treatment significantly increased the body weight of mice, the level of serum Ca2+, 25(OH)D and osteocalcin, ration of bone weight, bone volume/total volume, trabecular thickness, trabecular number, trabecular spacing and cortical thickness in osteoporosis mice. In BMSCs of osteoporosis mice, resveratrol treatment significantly increased the expression of Runx2, osterix (OSX) and osteocalcin (OCN) protein, the level of calcium deposition, ALP activity and osteocalcin content. In addition, resveratrol treatment also significantly increased the expression of SIRT1, p-PI3K / PI3K and p-AKT / AKT in BMSCs of osteoporosis mice. In vitro, resveratrol increased the expression of SIRT1, p-PI3K / PI3K and p-AKT / AKT, Runx2, OSX and OCN protein, the level of calcium deposition, ALP activity and osteocalcin content in BMSCs in a concentration-dependent manner, while SIRT1 knockdown significantly reversed the effect of resveratrol. Resveratrol can attenuate osteoporosis by promoting osteogenic differentiation of bone marrow mesenchymal stem cells, and the mechanism may be related to the regulation of SIRT1/PI3K/AKT pathway.

La osteoporosis senil es causada principalmente por una diferenciación reducida de osteoblastos y se ha convertido en la principal causa de fracturas en las personas mayores en todo el mundo. Los productos orgánicos naturales están surgiendo como una opción potencial para la prevención y el tratamiento de la osteoporosis. Este estudio fue diseñado para estudiar el efecto del resveratrol en la diferenciación osteogénica de las células madre mesenquimales de la médula ósea (BMSC) en ratones con osteoporosis. Se estableció un modelo de osteoporosis en ratones mediante inyección subcutánea de dexametasona y se trató con resveratrol administrado por sonda. In vivo e in vitro, utilizamos Western blot para detectar la expresión de proteínas y evaluamos la diferenciación osteogénica de BMSC detectando la expresión de proteínas relacionadas con la diferenciación osteogénica, la deposición de calcio, la actividad de ALP y el contenido de osteocalcina. El tratamiento con resveratrol aumentó significativamente el peso corporal de los ratones, el nivel sérico de Ca2+, 25(OH)D y osteocalcina, la proporción de peso óseo, el volumen óseo/ volumen total, el espesor trabecular, el número trabecular, el espaciado trabecular y el espesor cortical en ratones con osteoporosis. En BMSC de ratones con osteoporosis, el tratamiento con resveratrol aumentó significativamente la expresión de las proteínas Runx2, osterix (OSX) y osteocalcina (OCN), el nivel de deposición de calcio, la actividad de ALP y el contenido de osteocalcina. Además, el tratamiento con resveratrol también aumentó significativamente la expresión de SIRT1, p-PI3K/PI3K y p-AKT/AKT en BMSC de ratones con osteoporosis. In vitro, el resveratrol aumentó la expresión de las proteínas SIRT1, p-PI3K/PI3K y p- AKT/AKT, Runx2, OSX y OCN, el nivel de deposición de calcio, la actividad de ALP y el contenido de osteocalcina en BMSC de manera dependiente de la concentración, mientras que La caída de SIRT1 revirtió significativamente el efecto del resveratrol. El resveratrol puede atenuar la osteoporosis al promover la diferenciación osteogénica de las células madre mesenquimales de la médula ósea, y el mecanismo puede estar relacionado con la regulación de la vía SIRT1/PI3K/AKT.

Epidemiological characteristics of chronic obstructive pulmonary disease and influencing factors of acute exacerbation in Ma'anshan Area in 2020 - 2022 / 公共卫生与预防医学

Objective To study the epidemiological characteristics of chronic obstructive pulmonary disease (COPD) in Ma'anshan area and analyze the influencing factors of acute exacerbation. Methods The clinical data of 1 676 patients with COPD who visited the Department of Respiratory Medicine of Deyu Medical Ma'anshan General Hospital from 2020 to 2022 were retrospectively analyzed. The patients were divided into acute exacerbation group and stable group according to whether they had acute exacerbation or not，and the general information, severity of COPD, previous pulmonary infection and combined hypoproteinemia were compared between the two groups. Logistic regression was used to analyze the influencing factors of acute exacerbation. Results A total of 1 676 COPD patients were mainly male (58.17%) and ≥ 46 years old (82.58%), of which the incidence of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) was 78.82%. Logistic regression analysis showed that male sex , ≥46 years of age, smoking >400 cigarettes/year, occupational exposure to dust, severe and very severe COPD, recurrent new coronavirus infections, combined cardiovascular disease, or hypoproteinemia were risk factors for acute exacerbations in COPD patients. Conclusion Nearly 80% of COPD patients in Ma'anshan area have previously experienced acute exacerbations, and prevention and treatment cannot be ignored. Strengthening the education and prevention of key populations can effectively reduce the incidence of AECOPD and improve the overall prognosis of COPD patients.

The difference of regional homogeneity of resting-state brain activity between overweight and normal weight male patients with type 2 diabetes mellitus / 实用放射学杂志

Objective To explore the differences of regional homogeneity(ReHo)between overweight and normal weight male patients with type 2 diabetes mellitus(T2DM)during rest and their correlations with clinical features.Methods Twenty-five untreated male overweight T2DM(OW-T2DM)patients,25 untreated male normal weight T2DM(NW-T2DM)patients and 25 healthy controls(HC)were enrolled.The brain structure and resting-state functional magnetic resonance imaging(rs-fMRI)data were collected from all subjects.The brain structure and rs-fMRI data were preprocessed,and ReHo values of all brain regions were calculated for all subjects.ReHo values were compared among three groups and between groups respectively via the methods of one-way analysis of variance and two-sample t-test.To address the problem of multiple comparisons,the method of AlphaSim was performed(the threshold was set at P<0.005,the number of voxel clusters was>12).In addition,Pearson correlation analysis was performed to explore the relationships between ReHo values of the abnormal brain regions and clinical features in patients.Results(1)The brain regions showed differences of ReHo values among three groups were mainly distributed in the right hemisphere,including the superior parietal gyrus,superior marginal gyrus and superior occipital gyrus;(2)Compared with HC,NW-T2DM patients showed significantly decreased ReHo values in the right medial superior frontal gyrus,right middle cingulate gyrus and left anterior cingulate gyrus;(3)Compared with HC,OW-T2DM patients showed significantly decreased ReHo values in the bilateral postcentral gyrus and bilateral middle cingulate gyrus;(4)Compared with NW-T2DM patients,OW-T2DM patients showed significantly decreased ReHo values in the right superior parietal gyrus,right superior occipital gyrus and left cuneus;(5)ReHo values of the right medial superior frontal gyrus and right superior parietal gyrus were negatively correlated with hemoglobinA1c(HbA1c)level and body mass index(BMI),respectively,in all patients.Conclusion The occurrence of T2DM in male patients may lead to the declined activity of brain regions located in the default mode network(DMN),while overweight may further lead to decreased brain activity within the attention and visual recognition network in male T2DM patients.

Effect of miR-141-5p/ZNF705A on adhesion of bone marrow mesenchymal stem cells in chronic myeloid leukemia cell-derived exosomes / 中国药理学通报

Aim To investigate the effect of miR-141-5p/ZNF705A in chronic myeloid leukemia(CML)cell-derived exosome(Exo)on the adhesion of bone marrow mesenchymal stem cells(BMSCs). Methods The morphology and size of Exo in peripheral blood from CML patients and K562 cells were examined by electron microscopy and NTA particle size analysis. The expressions of Exo and BMSCs marker molecules and adhesion proteins in K562 cells were detected by qRT-PCR and Western blot before and after transfection. The adhesion ability of BMSCs was detected by cell adhesion assay, and the cellular activity of BMSCs was examined using CCK-8. miR-141-5p binding to ZNF705A was detected by luciferase assay. Results qRT-PCR results showed that miR-141-5p expression was significantly reduced in both CML patients and K562 cell-derived Exo. qRT-PCR, Western blot and other results showed that BMSCs in CML patients had significantly reduced the expression of adhesion proteins CD44 and CXCL12, and were able to phagocytose K562 cell-derived Exo. Further, K562-derived Exo was found to reduce CD44 and CXCL12 expression and adhesion in Exo-promoted BMSCs compared with CD34+ cells. Meanwhile, the results of dual luciferase reporter assay verified that miR-141-5p targeted binding to ZNF705A. Finally, we found ZNF705A could be targeted by up-regulating miR-141-5p expression in Exo of K562 cells, which in turn inhibited the adhesion of BMSCs. Conclusions K562 cells down-regulate miR-141-5p expression in Exo and inhibit the adhesion function of BMSCs by targeting ZNF705A, thus regulating the bone marrow hematopoietic function in CML patients.

Protective Effects of Danmu Extract Syrup on Acute Lung Injury Induced by Lipopolysaccharide in Mice through Endothelial Barrier Repair / 中国结合医学杂志

OBJECTIVE@#To investigate the effects of Danmu Extract Syrup (DMS) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and explore the mechanism.@*METHODS@#Seventy-two male Balb/C mice were randomly divided into 6 groups according to a random number table (n=12), including control (normal saline), LPS (5 mg/kg), LPS+DMS 2.5 mL/kg, LPS+DMS 5 mL/kg, LPS+DMS 10 mL/kg, and LPS+Dexamethasone (DXM, 5 mg/kg) groups. After pretreatment with DMS and DXM, the ALI mice model was induced by LPS, and the bronchoalveolar lavage fluid (BALF) were collected to determine protein concentration, cell counts and inflammatory cytokines. The lung tissues of mice were stained with hematoxylin-eosin, and the wet/dry weight ratio (W/D) of lung tissue was calculated. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1 β in BALF of mice were detected by enzyme linked immunosorbent assay. The expression levels of Claudin-5, vascular endothelial (VE)-cadherin, vascular endothelial growth factor (VEGF), phospho-protein kinase B (p-Akt) and Akt were detected by Western blot analysis.@*RESULTS@#DMS pre-treatment significantly ameliorated lung histopathological changes. Compared with the LPS group, the W/D ratio and protein contents in BALF were obviously reduced after DMS pretreatment (P<0.05 or P<0.01). The number of cells in BALF and myeloperoxidase (MPO) activity decreased significantly after DMS pretreatment (P<0.05 or P<0.01). DMS pre-treatment decreased the levels of TNF-α, IL-6 and IL-1 β (P<0.01). Meanwhile, DMS activated the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway and reversed the expressions of Claudin-5, VE-cadherin and VEGF (P<0.01).@*CONCLUSIONS@#DMS attenuated LPS-induced ALI in mice through repairing endothelial barrier. It might be a potential therapeutic drug for LPS-induced lung injury.

Ywhab inhibits growth of mouse B-cell lymphoma 38B9 cells by targeting HSP90aa1 / 中国病理生理杂志

AIM:To investigate the role of Ywhab in the growth of mouse B-cell lymphoma,and to explore the potential underlying mechanisms.METHODS:The correlation between Ywhab and human diffuse large B-cell lymphoma(DLBCL)was investigated by bioinformatics analysis.Infection with retroviral vector was performed to establish stable mouse B-cell lymphoma 38B9 cell line with overexpression of Ywhab gene,which was verified by RT-qPCR and Western blot.The impact of Ywhab overexpression on 38B9 cell growth both in vitro and in vivo was detected by cell counting,CCK-8 assay,and subcutaneous tumor loading experiments.The expression of apoptosis-related proteins was detected by RT-qPCR and Western blot.Co-immunoprecipitation combined with mass spectrometry(CoIP-MS)was employed to search for proteins specifically binding to Ywhab gene product 14-3-3β,which was confirmed by Western blot and molecu-lar docking analysis.RESULTS:The Ywhab gene exhibited low expression in DLBCL,which was correlated with poor clinical prognosis of DLBCL patients.Compared with normal mouse bone marrow B cells,Ywhab expression was low in 38B9 cells.Overexpression of Ywhab induced apoptosis of 38B9 cells both in vitro and in vivo,promoted the expression of pro-apoptotic proteins Puma,Noxa and Bax at both mRNA and protein levels,and inhibited the mRNA and protein expres-sion of anti-apoptotic protein Bcl2(P＜0.05).The 14-3-3β protein specifically bound to Hsp90aa1 and reduced Hsp90aa1 protein levels,thereby suppressing the growth of 38B9 cells.CONCLUSION:Ywhab promotes the apoptosis of B-cell lymphoma cells by binding to Hsp90aa1 and thereby inhibiting the function of Hsp90aa1.

Duração do Sono e Risco de Aterosclerose: Um Estudo Mendeliano de Randomização / Sleep Duration and the Risk of Atherosclerosis: A Mendelian Randomization Study

Resumo Fundamento: A associação entre a duração do sono e a aterosclerose foi relatada em muitos estudos observacionais. No entanto, pouco se sabe sobre a sua importância como fator de risco para aterosclerose ou como consequência negativa da aterosclerose. Objetivo: Este estudo teve como objetivo avaliar a associação causal entre a duração do sono e o risco de aterosclerose usando estatísticas resumidas de estudos de associação genômica ampla (GWAS) disponíveis publicamente. Métodos: Empregamos um método de randomização mendeliana (RM) de duas amostras com 2 coortes do MRC-IEU (n = 460.099) e do UK Biobank (n = 361.194) para investigar a associação causal entre a duração do sono e o risco de aterosclerose. Três métodos, incluindo a técnica de variância inversa ponderada (IVW), escore de perfil ajustado robusto (RAPS) e abordagem de mediana simples e ponderada, foram usados para obter resultados confiáveis, e uma razão de chances com intervalo de confiança (IC) de 95% foi calculada. P<0,05 foi considerado diferença estatística. Além disso, foram utilizadas análises de regressão: MR-Egger regression, Radial MR, MR-PRESSO e leave-one-out para avaliar os possíveis efeitos de pleiotropia. Resultados: Não foi encontrada associação causal entre duração do sono e aterosclerose [OR (IC95%): 0,90 (0,98-1,00), p = 0,186]. As análises Leave-one-out, MR-Egger, e MR-PRESSO não conseguiram detectar pleiotropia horizontal. Conclusões: Esta análise de RM não indicou nenhuma associação causal entre a duração do sono geneticamente prevista e a aterosclerose nas populações europeias.

Abstract Background: The association between the length of sleep and atherosclerosis has been reported in many observational studies. However, little is known about its significance as a risk factor for atherosclerosis or as a negative consequence of atherosclerosis. Objective: This study aimed to assess the causal association between sleep duration and the risk of atherosclerosis using publicly available genome-wide association studies (GWAS) summary statistics. Methods: We employed a two-sample Mendelian randomization (MR) method with 2 cohorts from MRC-IEU (n=460,099) and UK Biobank (n=361,194) to investigate the causal association between sleep duration and the risk of atherosclerosis. Three methods including the inverse-variance weighted (IVW) technique, Robust adjusted profile score (RAPS), and simple-and weighted-median approach were used to obtain reliable results, and an odds ratio with a 95% confidence interval (CI) was calculated. P<0.05 was considered as a statistical difference. In addition, MR-Egger regression, Radial MR, MR-PRESSO, and leave-one-out analyses were used to assess the possible pleiotropy effects. Results: No causal association of sleep duration with atherosclerosis was found [OR (95%CI): 0.90 (0.98-1.00), p = 0.186]. Leave-one-out, MR-Egger, and MR-PRESSO analyses failed to detect horizontal pleiotropy. Conclusions: This MR analysis indicated no causal association between genetically predicted sleep duration and atherosclerosis across European populations.

The effect of virtual reality technology in children after surgery for concomitant strabismus

Purpose: This study aimed to investigate the effect of virtual reality (VR) technology in children after surgery for concomitant strabismus. Methods: A total of 200 children with concomitant exotropia or concomitant esotropia were randomly divided into a training group and a control group according to the single even number random method (100 cases in each group). Patients in the training group received VR intervention training within 1 week after surgery. Patients in the control group did not receive any training. Results: Six months after the surgery, the orthophoria (the far or near strabismus degree was ?8?) rate was significantly higher in the training group than in the control group (P = 0.001), while the eye position regression rate (compared to the strabismus degree within 1 week after the surgery, the amount of regression >10?) was significantly lower in the training group than in the control group (P = 0.001). Six months after the surgery, the number of children with simultaneous vision and remote stereovision was significantly higher in the training group than in the control group (P = 0.017 and 0.002, respectively). The differences in the number of patients with peripheral stereopsis, macular stereopsis, and stereopsis in macular fovea centralis at 1, 3, and 6 months after the surgery between the training and the control groups were not statistically significant (P = 0.916, 0.274, and 0.302, respectively). Conclusion: The intervention of VR technology after strabismus correction effectively improved children’s visual function and maintained their eye position

Pharmaceutical analysis for a patient with rebamipide-induced Stevens-Johnson syndrome by clinical pharmacists / 中国药房

OBJECTIVE To provide reference for the diagnosis and treatment of Stevens-Johnson syndrome caused by rebamipide， and to explore the predisposing factors of Stevens-Johnson syndrome. METHODS Clinical pharmacists analyzed the treatment process of a patient with gastrointestinal diseases and evaluated the correlation between the drug used and adverse reactions， in order to determine the suspected allergenic drug causing Stevens-Johnson syndrome. The predisposing factors of patients with Stevens-Johnson syndrome were explored. RESULTS & CONCLUSIONS The suspected allergenic drugs that caused the patient to develop Stevens-Johnson syndrome included Ilaprazole enteric-coated tablets， Rebamipide tablets and Kangfuxin liquid. In summary， the suspect drug was identified as Rebamipide tablets according to the causality evaluation method of the National Center for Adverse Drug Reaction Monitoring， Naranjo’s scoring method and the algorithm of drug causality for epidermal necrolysis scoring criteria. Hypoproteinemia， competitive binding of plasma proteins between drugs， advanced age， bacterial and viral infections were the predisposing factors of Stevens-Johnson syndrome. Therefore， before using rebamipide in clinical practice， it is necessary to inquire about the patient’s allergy history in detail. During the use process， it is necessary to strengthen the patient’s medication monitoring and be alert to the occurrence of serious adverse reactions. If any abnormalities are found， the medication should be stopped immediately and symptomatic treatment should be given as soon as possible to ensure the safety and effectiveness of the patient’s medication.

Investigation of patient dose during digital mammography in Zigong, China, 2022 / 中国辐射卫生

Objective To investigate the average glandular dose of digital mammography in Zigong, China, and to explore the methods of reducing average glandular dose. Methods A total of 260 patients who underwent digital mammography at six hospitals located in Zigong during the year 2022 were included in this study. Their personal information, photography position, breast compression thickness, exposure parameters, and average glandular dose were collected. Analysis of variance and correlation analysis were performed for data analysis. Results Among the 260 patients who underwent digital mammography, the average breast compression thickness was 46.3 mm and the average glandular dose was 1.70 mGy. There was a significant difference in average glandular dose between patients with different breast compression thickness(P <0.05), and average glandular dose was positively correlated with breast compression thickness. There were no significant differences in average glandular dose between patients with different photography positions and patients with different ages (P>0.05). Conclusion The average glandular dose of patients undergoing digital mammography is at an acceptable level in Zigong. The average glandular dose is impacted by the breast compression thickness, target/filter, and exposure parameters. These factors should be optimized to reduce glandular dose during digital mammography.

Landmark vessel in membrane anatomy-based colorectal surgery / 中华胃肠外科杂志

The theory of membrane anatomy has been widely used in the field of colorectal surgery. The key point to perform high quality total mesorectal excision (TME) and complete mesocolic excision (CME) is to identify the correct anatomical plane. Intraoperative identification of the various fasciae and fascial spaces is the key to accessing the correct surgical plane and surgical success. The landmark vessels refer to the small vessels that originate from the original peritoneum on the surface of the abdominal viscera during embryonic development and are produced by the fusion of the fascial space. From the point of view of embryonic development, the abdominopelvic fascial structure is a continuous unit, and the landmark vessels on its surface do not change morphologically with the fusion of fasciae and have a specific pattern. Drawing on previous literature and clinical surgical observations, we believe that tiny vessels could be used to identify various fused fasciae and anatomical planes. This is a specific example of membrane anatomical surgery.

Research progress on intra-arterial thrombolysis for the treatment of central retinal artery occlusion / 国际眼科杂志(Guoji Yanke Zazhi)

Central retinal artery occlusion(CRAO), also known as eye stroke, always results in acute and painless visual loss. At present, conservative treatments, such as eye massage, lowering intraocular pressure and vasodilators have little effect on reducing visual loss. Intra-arterial thrombolysis(IAT)has significantly improved prognosis in patients with acute ischemic stroke, thus IAT has been gradually applied in the treatment of CRAO. IAT injects fibrinolytic drugs directly into the ophthalmic artery by a microcatheter, and dissolves the emboli that block the central retinal artery to restore the blood flow of the retina. Theoretically, IAT may be effective for CRAO as what has been found for stroke, but existing clinical studies exhibited inconsistent results. This paper summarizes the feasibility, efficacy, and safety of IAT treatment in CRAO. It will also analyze related factors that affect the prognosis, putting forward potential development directions and providing insights for the further clinical application of IAT.

Effects of mild/asymptomatic COVID-19 on semen parameters and sex-related hormone levels in men: a systematic review and meta-analysis / 亚洲男科学杂志(英文版)

Coronavirus disease 2019 (COVID-19) has yet to be proven to alter male reproductive function, particularly in the majority of mild/asymptomatic patients. The purpose of this study was to explore whether mild/asymptomatic COVID-19 affects semen quality and sex-related hormone levels. To find suitable comparative studies, a systematic review and meta-analysis was done up to January 22, 2022, by using multiple databases (Web of Science, PubMed, and Embase). Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to identify and choose the studies. Meta-analysis was used to examine the semen parameters and sex-related hormones of mild/asymptomatic COVID-19 patients before and after infection. The effects of semen collection time, fever, and intensity of verification on semen following infection were also investigated. A total of 13 studies (n = 770) were included in the analysis, including three case-control studies, six pre-post studies, and four single-arm studies. A meta-analysis of five pre-post studies showed that after infection with COVID-19, sperm concentration (I2 = 0; P = 0.003), total sperm count (I2 = 46.3%; P = 0.043), progressive motility (I2 = 50.0%; P < 0.001), total sperm motility (I2 = 76.1%; P = 0.047), and normal sperm morphology (I2 = 0; P = 0.001) decreased. Simultaneously, a systematic review of 13 studies found a significant relationship between semen collection time after infection, inflammation severity, and semen parameter values, with fever having only bearing on semen concentration. Furthermore, there was no significant difference in sex-related hormone levels before and after infection in mild/asymptomatic patients. Mild/asymptomatic COVID-19 infection had a significant effect on semen quality in the short term. It is recommended to avoid initiating a pregnancy during this period of time.

In combination with Jin's three needling, named "three-trembling needling" "three-governor-vessel needling" and "three-spasm needling", the triple-acupoint prescription is composed. To ensure the favorable therapeutic effect, this prescription is modified according to the symptoms and the specific techniques of acupuncture are combined such as conducting qi, harmonizing yin and yang, and manipulating gently for reinforcing and reducing.

A survey on disability status of patients with inflammatory bowel disease in China / 中华消化杂志

Objective:To investigate the disability status of patients with inflammatory bowel disease (IBD) in China and to identify the influencing factors of the inflammatory bowel disease disability index (IBD-DI).Methods:From October 1 to December 31, 2021, a total of 1 170 IBD patients were recruited from 7 IBD centers and WeChat public platforms in China. All the patients were surveyed by the IBD-DI questionnaire, which included demographic information, disease activity, medication history, treatment and surgical history. Demographic information included gender, age, income status, etc. Multiple linear regression was used to analyze the influencing factors of IBD-DI.Results:Among the 1 170 IBD patients, 746 patients (63.76%) were male and 424 patients (36.24%) were female; there were 871 cases (74.44%) of Crohn′s disease(CD), 277 cases (23.68%) of ulcerative colitis (UC) and 22 cases (1.88%) of inflammatory bowel disease undassified (IBDU). The age was 36.00 years old (29.00 years old, 45.00 years old), and the IBD-DI score was 9.00 (5.00, 15.00). The results of multiple linear regression analysis revealed that the disease activity ( β=0.65, t=22.33, P<0.001), current treatment with enteral nutrition ( β=0.09, t=3.06, P<0.001), and history of perianal surgery ( β=0.06, t=2.12, P=0.034) were influencing factors of IBD-DI in the CD patients. Disease activity ( β=0.65, t=14.37, P<0.001), household per capita annual income ( β=-0.16, t=-3.59, P<0.001), current usage of immunosuppressants ( β=0.12, t=2.66, P=0.008), current treatment with enteral nutrition ( β=0.12, t=2.57, P=0.011), and the duration of each exercise ( β=-0.12, t=-2.67, P=0.008) were influencing factors of IBD-DI in UC patients. Conclusions:Disability is common in Chinese IBD patients, and their IBD-DI were different. Disease activity is the most important factor affecting IBD-DI. The IBD-DI is higher in IBD patients receiving enteral nutrition treatment, CD patients with a history of perianal surgery and UC patients with current usage of immunosuppressants. However, household per capita annual income and the duration of each exercise are negatively correlated with IBD-DI in UC patients.

Clinical application and effectiveness of patellar tunnel locator in medial patellofemoral ligament reconstruction surgery / 中国修复重建外科杂志

OBJECTIVE@#To evaluate the operability and effectiveness of a self-developed patellar bone canal locator (hereinafter referred to as "locator") in the reconstruction of the medial patellofemoral ligament (MPFL).@*METHODS@#A total of 38 patients with recurrent patellar dislocation who met the selection criteria admitted between January 2022 and December 2022 were randomly divided into study group (the patellar canal was established with a locator during MPFL reconstruction) and control group (no locator was used in MPFL reconstruction), with 19 cases in each group. There was no significant difference in baseline data between the two groups ( P>0.05), such as gender, age, body mass index, disease duration, patella Wiberg classification, constituent ratio of cartilage injury, Caton index, tibia tubercle-trochlear groove, and preoperative Lysholm score, Kujal score, Tegner score, visual analogue scale (VAS) score, and so on. The Lysholm score, Kujal score, Tegner score, and VAS score were used to evaluate knee joint function before operation and at 3 days,1 month, 3 months, and 6 months after operation. The ideal prepatellar cortical thickness and canal length were measured before operation, and the actual prepatellar cortical thickness and canal length after operation were also measured, and D1 (the distance between the ideal entrance and the actual entrance), D2 (the ideal canal length minus the actual canal length), D3 (the ideal prepatellar cortical thickness minus the actual prepatellar cortical thickness) were calculated.@*RESULTS@#Patients in both groups were followed up 6-8 months (mean, 6.7 months). The incision length and intraoperative blood loss in the study group were smaller than those in the control group, but the operation time was longer than that in the control group, the differences were significant ( P<0.05). There was no complication such as incision infection, effusion, and delayed healing in both groups, and no further dislocation occurred during follow-up. One patient in the study group had persistent pain in the anserine area after operation, and the symptoms were relieved after physiotherapy. The VAS score of the two groups increased significantly at 3 days after operation, and gradually decreased with the extension of time; the change trends of Lysholm score, Kujal score, and Tegner score were opposite to VAS score. Except that the Lysholm score and Kujal score of the study group were higher than those of the control group at 3 days after operation, and the VAS score of the study group was lower than that of the control group at 3 days and 1 month after operation, the differences were significant ( P<0.05), there was no significant difference in the scores between the two groups at other time points ( P>0.05). Patellar bone canal evaluation showed that there was no significant difference in preoperative simulated ideal canal length, prepatellar cortical thickness, and postoperative actual canal length between the two groups ( P>0.05). The postoperative actual prepatellar cortical thickness of the study group was significantly smaller than that of the control group ( P<0.05). D1 and D3 in the study group were significantly higher than those in control group ( P<0.05), but there was no significant difference in D2 between the two groups ( P>0.05).@*CONCLUSION@#The locator can improve the accuracy of MPFL reconstruction surgery, reduce the possibility of intraoperative damage to the articular surface of patella and postoperative patellar fractures.
