RESUMEN

Traumatic osteomyelitis with accompanying soft tissue defects presents a significant therapeutic challenge. This prospective, randomised controlled trial aims to evaluate the efficacy of antibiotic-impregnated bone cement, flap coverage and negative pressure sealed irrigation in the management of traumatic osteomyelitis complicated by soft tissue defects. A total of 46 patients with clinically diagnosed traumatic osteomyelitis and soft tissue defects were randomised into a control group (n = 23) and an observation group (n = 23). The control group underwent standard flap coverage and negative-pressure lavage, while the observation group received an additional treatment with antibiotic-loaded bone cement. Efficacy was measured based on clinical criteria, surgical metrics and morphometric assessment of bone and soft tissue defects. Statistical analyses were performed using SPSS version 27.0. The observation group, treated with an integrated approach of flap coverage, negative pressure wound therapy (NPWT) and antibiotic-impregnated bone cement, demonstrated significantly higher overall treatment efficacy (91.3%) compared to the control group, which received only flap coverage and NPWT (65.2%) (p < 0.01). This enhanced efficacy was evidenced through various outcomes: the observation group experienced reduced surgical times, shorter hospital stays, fewer dressing changes and accelerated wound healing, all statistically significant (p < 0.001). Additionally, a quantitative analysis at 6-month post-treatment revealed that the observation group showed more substantial reductions in both bone and soft tissue defect sizes compared to the control group (p < 0.001). The multi-modal treatment strategy, combining skin flap coverage, antibiotic bone cement and negative-pressure irrigation, showed marked efficacy in treating traumatic osteomyelitis and associated soft tissue defects. This approach accelerated postoperative recovery and lowered costs.

RESUMEN

BACKGROUND: Hollow screw internal fixation is commonly used in clinical treatment of impacted femoral neck fractures. Previous studies have demonstrated a correlation between the preoperative posterior tilt angle of the femoral head and failure of internal fixation, but there are fewer studies related to the occurrence of postoperative femoral head necrosis and the posterior tilt angle. METHODS: To examine the relationship between three-dimensional posterior tilt angle measurements in affected femoral neck fractures and postoperative osteonecrosis of the femoral head and related risk variables. We retrospectively examined 130 Yantaishan Hospital patients with affected femoral neck fractures from 2019 to 2022. Three-dimensional reconstruction technology assessed the posterior tilt angle of the femoral head and separated patients into necrosis and non-necrosis groups based on postoperative femoral head necrosis. Univariate analysis compared clinical data between groups, and multivariate logistic regression analyzed risk variables for femoral head necrosis. Postoperative femoral head necrosis was predicted by posterior tilt angle using Receiver operating characteristic (ROC) curve analysis. RESULTS: Out of 130 patients who were followed up for 16-68 months postoperatively, 20 developed femoral head necrosis. Multivariate logistic regression analysis indicated that the posterior tilt angle and reduction quality level C were risk factors for the occurrence of femoral head necrosis. The ROC curve analysis showed that the three-dimensional measurement of the posterior tilt angle had predictive value for postoperative femoral head necrosis, with a cut-off value of 20.6°. CONCLUSIONS: These results suggest that, for patients with impacted femoral neck fractures, the posterior tilt angle and reduction quality level C are risk factors for femoral head necrosis following closed reduction and internal fixation surgery. Fracture patients with a posterior tilt angle ≥ 20.6°are more likely to experience postoperative femoral head necrosis.

RESUMEN

The purpose of the current study was to explore the immunomodulatory effects of different adjuvants combined with inactivated vaccines under Aeromonas veronii TH0426 infection in crucian carp. This study explored the best conditions for A. veronii as an inactivated vaccine, and included an animal safety test. Furthermore, we expressed the flagellin FlaA of the A. veronii TH0426 strain for use as an adjuvant supplemented in the diet. Crucian carp were fed 12 different experimental diets for 35 days, including the administration of 10 different adjuvants and inactivated vaccine combinations (50% aluminum hydroxide gel and inactivated vaccine combination, and inactivated vaccine with 20%, 30%, or 50% glucan, astragalus polysaccharide or flagellin), inactivated vaccine alone, and PBS control without adjuvant and inactivated vaccine. After the 42 day feeding trials, the fish were challenged with A. veronii TH0426, and the survival rate over 14 days was recorded. In addition, flagellin FlaA can be expressed normally in large amounts. All experimental groups produced higher levels of IgM serum titres than the control group in the different feeding cycles. Moreover, the activity of serum ACP, AKP, SOD, and LZM, and the expression of inflammatory factors were significantly increased in the experimental groups compared with the control group. The results of qRT-PCR analysis showed that the transcription levels of the IL-10, IL-1ß, IFN-γ and TNF-α genes in heart, liver, spleen and kidney tissues were significantly enhanced by adjuvant treatment, indicating that the addition of adjuvants can significantly promote the body's inflammatory response. In addition, the phagocytic activity of leukocytes in each adjuvant treated group was significantly enhanced compared to that in the groups without adjuvant. After the A. veronii challenge, the survival rate of all adjuvant-treated groups was significantly higher than that of the control group, and the 50% flagellin adjuvant group had the highest rate of 78.37%. Overall, our findings strongly indicate that adjuvants not only significantly improve the body's immunity, but also exhibit a strong anti-infection ability. Importantly, this work provides a new perspective for the prevention and control of aquaculture diseases.

RESUMEN

In order to improve the mechanical strength and imprinting efficiency, a novel bovine serum albumin (BSA) molecularly imprinted poly(ionic liquid)/calcium alginate composite cryogel membrane (MICM) was prepared. The results of the tensile test indicated that the MICM had excellent mechanical strength which could reach up to 90.00 KPa, 30.30 times higher than the poly (ionic liquid) membrane without calcium alginate; the elongation of it could reach up to 93.70%, 8.28 times higher than the poly (ionic liquid) membrane without calcium alginate. The MICM had a very high welling ratio of 1026.56% and macropore porosity of 62.29%, which can provide effective mass transport of proteins. More remarkably, it had a very high adsorption capacity of 485.87 mg g-1 at 20 °C and 0.66 mg mL-1 of the initial concentration of BSA. Moreover, MICM also had good selective and competitive recognition toward BSA, exhibiting potential utility in protein separation. This work can provide a potential method to prepare the protein-imprinted cryogel membrane with both high mechanical strength and imprinting efficiency.

RESUMEN

Autophagy is an important pro-survival mechanism and closely related to apoptosis. The aim of this study was to investigate whether hydroxychloroquine (HCQ) blocks autophagy and promotes apoptosis of the prostate after castration. METHODS: Thirty-six male SD rats were randomly divided into 3 groups (n = 12): control group (sham operation), castration group, and HCQ group (castrated and treated with HCQ). On day 7, all mice were executed and prostates were isolated. The morphological changes of prostates were observed by light microscope, and the ultrastructure changes were observed under scanning electron microscope (SEM). The protein expression of Beclin-l, P62, caspase-3, Bcl-2, and Bax was assessed by immunohistochemical analyses. The mRNA expression of microtubule-associated protein light chain 3 (LC3) and autophagy-related gene 5 (Atg5) was detected by RT-PCR. RESULTS: Prostates of castration group shrank remarkably and prostates of HCQ group shrank more remarkably than castration group. Cytolysosomes were visible in the prostates of the castration group under SEM. Immunohistochemistry showed that the protein of Beclin-1 increased in the castration group compared to the control group, while decreased in the HCQ group compared to the castration group. While P62 protein moderately dyed in the control group and weakly dyed in the castration group, it strongly dyed in the HCQ group. Caspase-3 and Bax protein were weakly dyed in the control group but moderately dyed in the castration group and strongly dyed in the HCQ group. The expressions of apoptosis suppressor Bcl-2 were reduced in the castration group and further reduced in the HCQ group compared to the castration group. RT-PCR revealed that the mRNA of LC3 and Atg5 in the castration group increased compared to the control group, while decreased after treated with HCQ. CONCLUSION: Autophagy increased after castrated in prostates, while decreased after treated with HCQ; all these indicated that HCQ blocked autophagy and then promoted prostate apoptosis of castrated mice.

RESUMEN

Diabetes mellitus (DM) is a chronic endocrine disease resulted from insulin secretory defect or insulin resistance and it is a leading cause of death around the world. The care of DM patients consumes a huge budget due to the high frequency of consultations and long hospitalizations, making DM a serious threat to both human health and global economies. Tea contains abundant polyphenols and caffeine which showed antidiabetic activity, so the development of antidiabetic medications from tea and its extracts is increasingly receiving attention. However, the results claiming an association between tea consumption and reduced DM risk are inconsistent. The advances in the epidemiologic evidence and the underlying antidiabetic mechanisms of tea are reviewed in this paper. The inconsistent results and the possible causes behind them are also discussed.

RESUMEN

Background Thoracoscopic-laparoscopic procedures have been used more in the operations of esophagus cancer; in most times we call it minimally invasive esophagectomy, which is becoming mature. However, the efficacy of minimally invasive esophagectomy is still unclear, especially about the dissection of lymph nodes and survival. Methods A retrospective review was performed. The development process of minimally invasive esophagectomy for esophageal cancer was divided into three stages: the first stage 20, the second stage 37, the third stage 50. Result Total 107 patients underwent minimally invasive esophagectomy between July 2010 and May 2015. The number of lymph node resected during the three stages increased significantly, with a mean of 12.65, 15.91, and 20.16 nodes, respectively (p = 0.0075). The number of lymph nodes dissection greater than or equal to 12 or 18 increased significantly (p = 0.000). The patients from the first and the second stages had the similar 2-year survival rate (p = 0.8618). There is no significant difference in the 2-year disease-free survival rate (p = 0.606). Conclusion Surgeons accumulate experience on lymphadenectomy during minimally invasive esophagectomy as time goes by, and experience on 50 to 60 cases is essential and necessary to accomplish an apparent progress.

RESUMEN

Joint contact forces measured with instrumented knee implants have not only revealed general patterns of joint loading but also showed individual variations that could be due to differences in anatomy and joint kinematics. Musculoskeletal human models for dynamic simulation have been utilized to understand body kinetics including joint moments, muscle tension, and knee contact forces. The objectives of this study were to develop a knee contact model which can predict knee contact forces using an inverse dynamics-based optimization solver and to investigate the effect of joint constraints on knee contact force prediction. A knee contact model was developed to include 32 reaction force elements on the surface of a tibial insert of a total knee replacement (TKR), which was embedded in a full-body musculoskeletal model. Various external measurements including motion data and external force data during walking trials of a subject with an instrumented knee implant were provided from the Sixth Grand Challenge Competition to Predict in vivo Knee Loads. Knee contact forces in the medial and lateral portions of the instrumented knee implant were also provided for the same walking trials. A knee contact model with a hinge joint and normal alignment could predict knee contact forces with root mean square errors (RMSEs) of 165 N and 288 N for the medial and lateral portions of the knee, respectively, and coefficients of determination (R2) of 0.70 and -0.63. When the degrees-of-freedom (DOF) of the knee and locations of leg markers were adjusted to account for the valgus lower-limb alignment of the subject, RMSE values improved to 144 N and 179 N, and R2 values improved to 0.77 and 0.37, respectively. The proposed knee contact model with subject-specific joint model could predict in vivo knee contact forces with reasonable accuracy. This model may contribute to the development and improvement of knee arthroplasty.

RESUMEN

BACKGROUND: Surgical treatment of extensive tracheal lesions remains a major challenge because of lack of an ideal airway substitute that is well vascularized, rigid, and autologous. We describe a novel surgical technique of tracheal reconstruction using a combination of a polypropylene mesh material and anterior cervical myocutaneous flap in a dog model. MATERIALS AND METHODS: A 3.5-4 cm length of cervical trachea was resected in 16 dogs and replaced with a myocutaneous cervical neck flap wrapped around the plain polypropylene tube (group 1, n = 7) or wrapped around a composite of polypropylene tube with an implanted Z-type metallic-covered stent (group 2, n = 9). The cervical tracheal defect was repaired with the previously mentioned substitute that was directly sutured to the remaining tracheal ends. Dogs were followed up using bronchoscopy and x-rays and euthanized at predetermined times for histologic examination. RESULTS: In group 1, four dogs died within 2 wk from respiratory failure with varying degrees of airway collapse and difficulties in expectoration. In group 2, eight dogs survived, whereas one died of anastomotic dehiscence 1 wk after surgery. Necropsy and histologic examination of the anastomotic sites revealed good healing tissue. Pathologic examination also revealed excellent healing of the squamous epithelium of the neotrachea and the columnar epithelium of the native tracheal mucosa. CONCLUSIONS: The tissue compatibility of the polypropylene mesh material and anterior cervical myocutaneous skin flap makes this a promising therapeutic substitute for treatment of patients with extensive tracheal lesions.

RESUMEN

A series of structurally unique second mitochondria-derived activator of caspases (Smacs) that act as antagonists of the inhibitor of apoptosis proteins (IAPs) directly have been discovered. They play crucial roles in mitochondrial apoptosis pathways and promote chemotherapy-induced apoptosis. In this study, we constructed a eukaryotic expression vector pcDNA3.1/Smac and transfected it into A549 human lung cancer cells. Then we analyzed the cell invasive and cloning ability, as well as cell apoptosis induced by Taxol. The results showed that over-expressed Smac significantly inhibited A549 cell invasive and cloning ability and promoted apoptosis following Taxol treatment. This finding provides a potential approach for the biological therapy of lung cancer.

RESUMEN

Spontaneous ventilation video-assisted thoracoscopic surgery (SV-VATS) has rapidly developed in recent years. The application scope is still being continuously explored. We describe a case in which a 40-year-old woman with mixed ground-glass opacity (GGO) and an esophageal leiomyoma successfully underwent simultaneous segmentectomy and leiomyoma resection through spontaneous ventilation video-assisted thoracoscopic surgery. The perioperative course was uneventful. Postoperative pathology revealed minimally invasive adenocarcinoma and esophageal leiomyoma.

RESUMEN

OBJECTIVE: To explore the role of Syk and VEGF-C in the development of NSCLC. METHODS: Transfered these genes(eukaryotic expression vector pcDNA3.1-VEGF-C and pLNCX-syk)into A549 cells with the liposomes. Tested the expression of VEGF-C mRNA and Syk mRNA with RT-PCR.Investigated the cell invasion assay with transwell chamber in vitro. Analysis the expression of VEGF-C proteins in A549 cells and detect Syk and VEGF-C proteins of 81 NSCLC tissue samples with immunohistochemical staining. RESULTS: Higher expression of VEGF-C was revealed in VEGF-C-construct-transfected A549 cell than that in controls through RT-PCR (P < 0.05) and immunohistochemistry(P < 0.01).RT-PCR also revealed that Syk expression was higher in Syk-construct-transfected cells than in controls (P < 0.05). The cell invading experiments showed that there was more invaded cells in both transfected terms than in controls (P < 0.05). The expression of Syk protein in NSCLC tissue were significantly lower than that in the normal lung tissue (P < 0.05), while the expression of VEGF-C protein in NSCLC tissue were significantly higher than that in the normal lung tissue(P < 0.05). The expression of Syk and VEGF-C has a negative correlationship (r = -1.000, P = 0.019). CONCLUSION: The expression of Syk and VEGF-C has a negative correlationship in NSCLC tissue, VEGF-C-construct-transfected A549 cells are more aggressive than Syk-construct-transfected cells. And they may cooperated with each other in the development of NSCLC.

RESUMEN

BACKGROUND: Femoral neck fractures represent a significant public health concern, particularly in the elderly population. A thorough understanding and assessment of these fractures are deemed essential for optimal treatment and management. Displacement characteristics of Garden III femoral neck fractures were explored in this study, and the reliability, validity, and clinical utility of the anteroposterior Garden Index in evaluating displacement severity were investigated. METHODS: Patients diagnosed with Garden III femoral neck fractures were included in this study. The anteroposterior Garden Index was computed from X-ray images by three experienced orthopedic doctors. Additionally, the contact area of the fracture endpoint and displacement of the femoral neck were evaluated using 128-slice 3D CT scans. Inter-observer and retest reliability of the Garden Index measurements were assessed, along with its correlation with CT measurements. RESULTS: In this study, a total of 110 patients with Garden III femoral neck fractures were analyzed, showcasing an almost equal gender distribution and an age range spanning from 20 to 88 years. An average Garden Index of 135° (± 16°) was observed. The intra-observer repeatability of the Garden Index was found to exceed 90%. A significant positive correlation was identified between the Garden Index and the contact surface area of the fracture endpoint (r = 0.82, P < 0.001), while a significant negative correlation was noted with the upward displacement of the femoral neck (r = - 0.79, P < 0.001). CONCLUSIONS: The anteroposterior Garden Index has been demonstrated to have promising potential as a reliable and valid tool for assessing the displacement severity of Garden III femoral neck fractures. Nonetheless, further research is needed to elucidate its relationship with other fracture characteristics and to enhance its criterion and construct validity.

RESUMEN

Articular cartilage repair is a sophisticated process that has is being recently investigated. There are several different approaches that are currently reported to promote cartilage repair, like cell-based therapies, biologics, and physical therapy. Cell-based therapies involve the using stem cells or chondrocytes, which make up cartilage, to promote the growth of new cartilage. Biologics, like growth factors, are also being applied to enhance cartilage repair. Physical therapy, like exercise and weight-bearing activities, can also be used to promote cartilage repair by inducing new cartilage growth and improving joint function. Additionally, surgical options like osteochondral autograft, autologous chondrocyte implantation, microfracture, and others are also reported for cartilage regeneration. In the current literature review, we aim to provide an up-to-date discussion about these approaches and discuss the current research status.

RESUMEN

In recent years, as the number of adults seeking orthodontic treatment has increased, so too has the number of periodontal tissue problems, particularly regarding the impact on periodontal tissue of receiving orthodontic treatment. Orthodontic treatment improves the occlusion and appearance of teeth by moving the teeth appropriately. These movements have a significant impact on the interactions between the teeth and periodontal tissues. Orthodontic treatment can also recover tooth alignment for patients with tooth displacement caused by periodontitis; however, orthodontic treatment also often has adverse effects on periodontal soft tissue, such as gingivitis, gingival enlargement and gingival recession. The purpose of this review is to summarise the current evidence and solid knowledge of periodontal soft tissue problems in orthodontic treatment and outline some prevention strategies.

RESUMEN

Objective. Non-primary radiation doses to normal tissues from proton therapy may be associated with an increased risk of secondary malignancies, particularly in long-term survivors. Thus, a systematic method to evaluate if the dose level of non-primary radiation meets the IEC standard requirements is needed.Approach. Different from the traditional photon radiation therapy system, proton therapy systems are composed of several subsystems in a thick bunker. These subsystems are all possible sources of non-primary radiation threatening the patient. As a case study, 7 sources in the P-Cure synchrotron-based proton therapy system are modeled in Monte Carlo (MC) code: tandem injector, injection, synchrotron ring, extraction, beam transport line, scanning nozzle and concrete reflection/scattering. To accurately evaluate the synchrotron beam loss and non-primary dose, a new model called the torus source model is developed. Its parametric equations define the position and direction of the off-orbit particle bombardment on the torus pipe shell in the Cartesian coordinate system. Non-primary doses are finally calculated by several FLUKA simulations.Main results. The ratios of summarized non-primary doses from different sources to the planned dose of 2 Gy are all much smaller than the IEC requirements in both the 15-50 cm and 50-200 cm regions. Thus, the P-Cure synchrotron-based proton therapy system is clean and patient-friendly, and there is no need an inner shielding concrete between the accelerator and patient.Significance. Non-primary radiation dose level is a very important indicator to evaluate the quality of a PT system. This manuscript provides a feasible MC procedure for synchrotron-based proton therapy with new beam loss model. Which could help people figure out precisely whether this level complies with the IEC standard before the system put into clinical treatment. What' more, the torus source model could be widely used for bending magnets in gantries and synchrotrons to evaluate non-primary doses or other radiation doses.

RESUMEN

The immunogenicity of Aha1, an OMP of Aeromonas hydrophila mediating the adhesion of bacteria onto the mucosal surface of hosts has been established. In this study, recombinant vectors, pPG1 and pPG2, carrying a 1366 bp DNA fragment that was responsible for encoding the 49 kDa Aha1 from A. hydrophila were constructed, respectively, then electroporated into a probiotic strain Lactobacillus casei CC16 separately to generate two types of recombinants, L. casei-pPG1-Aha1 (Lc-pPG1-Aha1) and L. casei-pPG2-Aha1 (Lc-pPG2-Aha1). Subsequently, these were orally administered into common carps to examine their immunogenicity. The expression and localization of the expressed Aha1 protein relative to the carrier L. casei was validated via Western blotting, flow cytometry, and immune fluorescence separately. The recombinant vaccines produced were shown high efficacies, stimulated higher level of antibodies and AKP, ACP, SOD, LZM, C3, C4 in serum in hosts. Immune-related gene expressions of cytokines including IL-10, IL-1ß, TNF-α, IFN-γ in the livers, spleens, HK, and intestines were up-regulated significantly. Besides, a more potent phagocytosis response was observed in immunized fish, and higher survival rates were presented in common carps immunized with Lc-pPG1-Aha1 (60%) and Lc-pPG2-Aha1 (50%) after re-infection with virulent strain A. hydrophila. Moreover, the recombinant L. casei were shown a stronger propensity for survivability in the intestine in immunized fish. Taken together, the recombinant L. casei strains might be promising candidates for oral vaccination against A. hydrophila infections in common carps.

RESUMEN

OBJECTIVE: Increasing evidence has indicated that there is a correlation between Fusobacterium nucleatum (F. nucleatum) abundance and poor prognosis of colorectal cancer (CRC). Furthermore, tumor metastasis plays a decisive role in the prognosis of CRC patients. Therefore, it was hypothesized that the abundance of F. nucleatum in CRC tissues affects the tumor metastasis. METHODS: In the present study, F. nucleatum DNA obtained from 141 resected CRC samples was quantified by qPCR to determine whether there were differences in F. nucleatum abundance between groups with and without CRC metastasis. RESULTS: The results revealed that F. nucleatum was more abundant in CRC patients with metastasis, and CRC tissues enriched with F. nucleatum had a higher risk of lymph node metastasis and distant metastasis. The receiver operating characteristic curve indicated that F. nucleatum in CRC tissues could be used as an indicator for CRC metastasis, to some extent. Furthermore, the in vitro experiments (electron microscopy, and migration and invasion trials) revealed that F. nucleatum was a highly invasive bacterial strain, and could significantly enhance the invasion and migration capacity of SW480 and SW620 cells. In addition, a meta-analysis comprehensively indicated a slight correlation between F. nucleatum abundance and advanced CRC stage (RR=1.17, 95% CI: 1.00-1.37, P=0.04, random effect). CONCLUSION: There is a correlation between F. nucleatum abundance and CRC metastasis, and F. nucleatum may serve as a metastasis biomarker for CRC patients.

RESUMEN

BACKGROUND: Pain due to chronic soft tissue injury of the neck and shoulder is a commonly encountered and frequently occurring condition. Traditional Chinese medicine is a common course of treatment for soft tissue injury and may have better therapeutic effects than biomedical options. OBJECTIVE: To evaluate the clinical therapeutic effects of Chinese herbal medicine warming meridians to nourish blood on chronic pain due to soft tissue injury in the neck and shoulder. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: A random and control method was adopted. Sixty-three patients with pain of the neck and shoulder due to chronic soft tissue injury, presenting with blood deficiency and cold coagulation syndrome, were randomly divided into treatment group (n=32) and control group (n=31). There was a drop-out case in treatment group. All the patients were collected from the clinic service of the Department of Rehabilitation at the General Hospital of the People's Liberation Army. Patients received oral and written information about clinical procedures before signing their written informed consent. Patients in the treatment group were treated with Chinese herbal decoctions for warming meridians to nourish blood and cervical traction. Patients in the control group were treated with cervical traction. The course of treatment was 14 days. MAIN OUTCOME MEASURES: A visual analog scale (VAS) was used to record test data in the two groups before and after treatment, and therapeutic effect was compared after treatment between the two groups. RESULTS: After treatment, VAS scores of the treatment group and the control group were decreased as compared with before treatment (t=5.01, P<0.01; t=4.91, P<0.01). Difference of VAS scores between before and after treatment in the treatment group was higher than that in the control group (t=2.44, P0.05). CONCLUSION: The treatment method of warming meridians to nourish blood combined with cervical traction has better therapeutic effect than only applying traction for chronic pain due to soft tissue injury of the neck and shoulder.
