RESUMEN

Objective:To establish and assess the precision of pre-surgical condyle position planning using mandibular movement trajectory data for orthognathic surgery.Methods:Skull data from large-field cone beam computed tomography(CBCT)and dental oral scan data were imported into IVSPlan 1.0.25 software for 3D reconstruction and fusion,creating 3D models of the maxilla and mandible.Trajectory da-ta of mandibular movement were collected using a mandibular motion recorder,and the data were inte-grated with the jaw models within the software.Subsequently,three-dimensional trajectories of the con-dyle were obtained through matrix transformations,rendering them visually accessible.A senior oral and maxillofacial surgeon with experience in both diagnosis and treatment of temporomandibular joint disease and orthognathic surgery selected the appropriate condyle position using the condyle movement trajectory interface.During surgical design,the mobile mandibular proximal segment was positioned accordingly.Routine orthognathic surgical planning was completed by determining the location of the mandibular distal segment,which was based on occlusal relationships with maxilla and facial aesthetics.A virtual mandible model was created by integrating data from the proximal and distal segment bone.Subsequently,a solid model was generated through rapid prototyping.The titanium plate was pre-shaped on the mandibular model,and the screw hole positions were determined to design a condylar positioning guide device.In accordance with the surgical plan,orthognathic surgery was performed,involving mandibular bilateral sagittal split ramus osteotomy(SSRO).The distal segment of the mandible was correctly aligned inter-maxillary,while the proximal bone segment was positioned using the condylar positioning guide device and the pre-shaped titanium plate.The accuracy of this procedure was assessed in a study involving 10 patients with skeletal class Ⅱ malocclusion.Preoperative condyle location planning and intraoperative po-sitioning were executed using the aforementioned techniques.CBCT data were collected both before the surgery and 2 weeks after the procedure,and the root mean square(RMS)distance between the preope-rative design position and the actual postoperative condyle position was analyzed.Results:The RMS of the condyle surface distance measured was(1.59±0.36)mm(95％CI:1.35-1.70 mm).This value was found to be significantly less than 2 mm threshold recommended by the expert consensus(P＜0.05).Conclusion:The mandibular trajectory may play a guiding role in determining the position of the mandibular proximal segment including the condyle in the orthognathic surgery.Through the use of a con-dylar positioning guide device and pre-shaped titanium plates,the condyle positioning can be personalized and customized with clinically acceptable accuracy.

RESUMEN

Objective:To investigate the regulatory effect of transient receptor potential cation channel subfamily C member 3 (TRPC3) on the retina in oxygen-induced retinopathy (OIR) mice and biological behavior of human retinal vascular endothelial cells (HREC).Methods:A total of 32 healthy SPF grade 7-day-old C57BL/6 mice were selected and randomly divided into a control group and an OIR group by the random number table method, with 16 mice in each group.The control group received no special treatment, and the OIR model was established in the OIR group.On postnatal day 17 (PN17), the success of the model establishment was verified by immunofluorescence staining of the retinal patch.The in vitro cultured HREC were divided into a normal control group, a transfection reagent group, and a si-TRPC3 group.The normal control group received no special treatment, while the transfection reagent group and the si-TRPC3 group were transfected with transfection reagent or transfection reagent + si-TRPC3.The relative expression of TRPC3 mRNA was detected by real-time quantitative fluorescence PCR.The relative expressions of TRPC3, transcription factor NF-E2 related factor (Nrf2), and superoxide dismutase (SOD) proteins were determined by Western blot.HREC were further divided into a normal control group, a vascular endothelial growth factor (VEGF) group, a si-TRPC3 group, and a Pyr3 (TRPC3 channel inhibitor) group, which were cultured in complete medium, medium containing 20 ng/ml VEGF recombinant protein, medium containing 20 ng/ml VEGF recombinant protein (si-TRPC3 transfection for 72 hours), and medium containing 20 ng/ml VEGF recombinant protein+ 1 μmol/L Pyr3 for 48 hours, respectively.The proliferation ability of HREC was detected using cell counting kit 8 (CCK-8). The horizontal and vertical migration ability of cells were detected by cell scratch assay and transwell assay, respectively.This study followed the 3R principles of animal welfare and was approved by the Ethics Committee of Hebei Eye Hospital (No.2023LW04). Results:Pathological neovascular clusters with strong fluorescent staining appeared in the retina of OIR mice on PN17.The relative expressions of TRPC3 mRNA and protein in the retina of OIR mice were 2.057±0.244 and 1.517±0.290, respectively, significantly higher than 0.983±0.033 and 0.874±0.052 of control group ( t=6.165, 3.094; both at P<0.05). The relative expression levels of TRPC3 mRNA and protein were significantly lower, and the relative expression levels of Nrf2 and SOD proteins were higher in the si-TRPC3 group than in the normal control and transfection reagent groups, and the differences were statistically significant (all at P<0.05). The CCK-8 experiment results showed that the cell absorbance value was higher in the VEGF group than in the normal control group, and lower in the si-TRPC3 and Pyr3 groups than in the VEGF group, with statistically significant differences (all at P<0.05). The results of the cell scratch experiment showed that the lateral migration rate of VEGF group cells was higher than that of normal control group, while the lateral migration rate of si-TRPC3 group and Pyr3 group cells was lower than that of VEGF group, and the differences were statistically significant (all at P<0.05). The transwell experiment results showed that the number of stained cells in the VEGF group was higher than that in the normal control group, and the number of stained cells in the si-TRPC3 group and Pyr3 group was lower than that in the VEGF group, with statistically significant differences (all at P<0.05). Conclusions:Hypoxia induces increased TRPC3 expression in OIR mouse retina, and downregulation of TRPC3 inhibits HREC proliferation and migration.The mechanism is related to the activation of the Nrf2-related oxidative stress pathway.

RESUMEN

The cardiovascular system plays a crucial role in the entire organism. It performs many important functions, such as providing organs and tissues with nutrients, hormones, delivering oxygen to cells, and maintaining physiological temperature. For a long time, accurately identifying the nonlinear and anisotropic mechanical properties of the vascular wall within the body has been regarded as a key challenge in cardiovascular biomechanics, as these properties are critical determinants of overall cardiac function. Currently, the roles of mechanical and tissue properties in cardiovascular diseases such as arterial aneurysms and atherosclerosis remain hot topics in both basic and clinical researches. This review aims to summarize the latest research advances in the field of cardiovascular biomechanics and mechanobiology in the year 2022. In terms of cardiovascular biomechanics, researchers focus on the structure, function, and pathophysiology of the cardiovascular system, and use experimental methods such as mechanical modeling to study these issues. These include studies about biomechanical properties of diseases such as atherosclerosis, arterial aneurysms, and myocardial infarction, as well as the development and testing of treatment methods based on dynamics of the cardiovascular system. In terms of mechanobiology, researchers explore mechanical properties of cardiovascular cells and extracellular matrix, including prediction of cell mechanical properties based on machine learning, studies of biological material mechanical properties, and the role of mechanical properties in cardiovascular cell phenotype changes. These research findings provide new ideas and methods for diagnosing and treating cardiovascular diseases and offer new insights into researches in biomechanics and mechanobiology fields.

RESUMEN

Objective:To analyze the clinical features and the effects of different treatments on 5-year overall survival (OS) rate and 5-year disease free survival (DFS) rate of stage 0-Ⅲ triple-negative breast cancer (TNBC).Methods:The data of 209 patients diagnosed as stage 0-Ⅲ TNBC in Ward 2 of Department of General Surgery of the Fifth Medical Center of PLA General Hospital from January 2004 to December 2013 were selected. The relationships between the clinical features, treatments and 5-year OS rate, 5-year DFS rate were retrospectively analyzed. Kaplan-Meier method was used to draw survival curves, and Cox proportional risk model was used for multivariate analysis.Results:Univariate analysis found that clinical stage and methods of surgery were associated with 5-year OS rate ( χ2=52.615, P<0.001; χ2=17.329, P=0.001) and 5-year DFS rate ( χ2=55.112, P<0.001; χ2=18.816, P<0.001). Multivariate analysis showed that clinical stage was an independent prognostic factor of DFS ( HR=3.637, 95% CI: 2.146-6.164, P<0.001) and OS ( HR=3.545, 95% CI: 2.091-6.009, P<0.001). For the TNBC patients without axillary lymph node metastasis ( n=118), the 5-year OS rates of patients with breast conservation surgery + sentinel lymph node biopsy, total breast resection + sentinel lymph node biopsy, modified radical mastectomy and breast conserving surgery + axillary lymph node dissection were 97.6%, 97.7%, 91.4%, 100% respectively, the 5-year DFS rates were 97.3%, 94.3%, 85.8%, 100% respectively, and there were no significant differences among the four groups ( χ2=3.369, P=0.338; χ2=3.868, P=0.276). The 5-year OS rate (74.5% vs. 91.1%) and 5-year DFS rate (73.6% vs. 86.8%) were significantly different in patients receiving neoadjuvant chemotherapy ( n=106) compared with those receiving adjuvant chemotherapy ( n=80) ( χ2=4.504, P=0.034; χ2=4.683, P=0.030). The patients receiving neoadjuvant chemotherapy had later clinical stages than those receiving adjuvant chemotherapy ( χ2=35.314, P<0.001). There were no significant differences in 5-year OS rate and 5-year DFS rate between the patients receiving neoadjuvant chemotherapy and adjuvant chemotherapy with the same clinical stage (all P>0.05). The 5-year OS rates of patients with pathologic complete response (pCR), partial response (PR) and stable disease (SD) obtained by neoadjuvant chemotherapy were 100%, 75.8% and 57.1% respectively, and the 5-year DFS rates were 100%, 74.5% and 55.7% respectively, with statistically significant differences ( χ2=10.086, P=0.006; χ2=10.399, P=0.006). Between the pCR group and the PR group, the 5-year OS rate ( χ2=4.238, P=0.040) and 5-year DFS rate ( χ2=4.525, P=0.033) were significantly different. Between the pCR group and the SD group, the 5-year OS rate ( χ2=8.163, P=0.004) and 5-year DFS rate ( χ2=8.509, P=0.004) were significantly different. Between the PR group and the SD group, the 5-year OS rate ( χ2=3.931, P=0.047) and 5-year DFS rate ( χ2=3.896, P=0.048) were significantly different. Conclusion:For the patients with stage 0-Ⅲ TNBC, clinical stage is an independent prognostic factor. For the TNBC patients without axillary lymph node metastasis, breast conservation surgery + sentinel lymph node biopsy, total breast resection + sentinel lymph node biopsy, modified radical mastectomy and breast conserving surgery + axillary lymph node dissection have similar outcomes. There is no significant difference between neoadjuvant chemotherapy and adjuvant chemotherapy in the prognosis of patients with the same clinical stage, but patients with pCR or PR obtained by neoadjuvant chemotherapy can achieve better survival.

RESUMEN

Pulp loss is accompanied by the functional impairment of defense, sensory, and nutrition supply. The approach based on endogenous stem cells is a potential strategy for pulp regeneration. However, endogenous stem cell sources, exogenous regenerative signals, and neovascularization are major difficulties for pulp regeneration based on endogenous stem cells. Therefore, the purpose of our research is to seek an effective cytokines delivery strategy and bioactive materials to reestablish an ideal regenerative microenvironment for pulp regeneration. In in vitro study, we investigated the effects of Wnt3a, transforming growth factor-beta 1, and bone morphogenetic protein 7 (BMP7) on human dental pulp stem cells (h-DPSCs) and human umbilical vein endothelial cells. 2D and 3D culture systems based on collagen gel, matrigel, and gelatin methacryloyl were fabricated to evaluate the morphology and viability of h-DPSCs. In in vivo study, an ectopic nude mouse model and an in situ beagle dog model were established to investigate the possibility of pulp regeneration by implanting collagen gel loading BMP7. We concluded that BMP7 promoted the migration and odontogenic differentiation of h-DPSCs and vessel formation. Collagen gel maintained the cell adhesion, cell spreading, and cell viability of h-DPSCs in 2D or 3D culture. The transplantation of collagen gel loading BMP7 induced vascularized pulp-like tissue regeneration in vivo. The injectable approach based on collagen gel loading BMP7 might exert promising therapeutic application in endogenous pulp regeneration.

RESUMEN

【Objective】 To investigate the regulation of HCBP6 mimic phosphorylation on triglyceride synthesis in hepatocytes so as to provide a molecular target for the treatment of metabolism-associated fatty liver disease. 【Methods】 We used site-directed mutagenesis to mimic constitutive phosphorylation and dephosphorylation of HCBP6 Ser-10 and Ser-151. Oil red O staining and triglyceride content determination were used to detect triglyceride levels in hepatocytes. The expressions of SREBP1c, ACC1 and FASN were detected by qRT-PCR and Western blotting. The Dual-Luciferase Report Gene System was used to detect SREBP1c promoter activity. 【Results】 HCBP6 Ser-10 phosphorylation promoted triglyceride synthesis. HCBP6 Ser-10 phosphorylation upregulated the expressions of SREBP1c, ACC1and FASN genes; HCBP6 Ser-10 phosphorylation enhanced the SREBP1c promoter activity. 【Conclusion】 HCBP6 Ser-10 phosphorylation can significantly enhance the activity of the SREBP1c promoter, upregulate the SREBP1c-FASN signal pathway transduction, and promote the synthesis of triglycerides.

RESUMEN

ObjectiveObjective To systematically evaluate the efficacy and safety of antiviral therapy in patients with chronic hepatitis B (CHB) in the immune-tolerant phase. MethodsPubMed, Embase, Cochrane Library, CNKI, and Wanfang Data were searched for clinical trials of antiviral therapy for CHB patients in the immune-tolerant phase published up to September 2020. Related data were extracted after quality assessment for systematic review. HBV DNA clearance rate was the primary outcome. ResultsA total of 9 studies involving 821 patients were included. Eight studies reported HBV DNA clearance rate in the treatment group, among which 6 studies had an HBV DNA clearance rate of ＞60%, which was significantly higher than that in the untreated patients (0%-29.1%), and the combination therapy group had a better clearance rate than the monotherapy group. However, virologic recurrence was more common in the long term. Eight studies reported HBeAg seroconversion, and only 2 studies of the treatment of children with interferon-α (IFN-α) reported a seroconversion rate of ＞20% in the treatment group, which was higher than that in the untreated group. HBsAg clearance was observed in 2 studies of IFN-α treatment, while HBsAg seroconversion was not observed. One study reported the risk of liver cirrhosis and hepatocellular carcinoma (HCC) and showed that antiviral therapy could reduce the risk of liver cirrhosis and HCC in patients. The incidence rate of adverse events ranged from 4.1%-13.0% in the treatment with nucleos(t)ide analogues and reached 100% in the treatment with IFN-α, and serious adverse events were rare. ConclusionThe majority of CHB patients in the immune-tolerant phase show satisfactory virologic response after antiviral therapy, but they tend to experience recurrence after drug withdrawal and have a low seroconversion rate. Antiviral therapy has good safety. Current evidence suggests that such patients can be dynamically observed if there is no clear evidence for disease progression.

RESUMEN

Objective:To investigate the effects of modified Sijunzi Decoction on myelosuppression in moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency and analyze the underlying mechanism. Methods:A total of 100 moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency who received treatment in Lishui Hospital of Traditional Chinese Medicine, China were included in this study. They were randomly assigned to receive chemotherapy with paclitaxel combined with cisplatin (control group, n = 50) or treatment with modified Sijunzi Decoction based on chemotherapy with paclitaxel combined with cisplatin (observation group, n = 50). Myelosuppression, traditional Chinese medicine symptom score, cellular immune function, serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor, and the dosage of recombinant human granulocyte-colony stimulating factor. Results:After treatment, the incidence of leucopenia, thrombocytopenia, hemoglobinopenia and neutropenia in the observation group were 60% (30/50), 18% (9/50), 18% (9/50) and 62% (31/50), respectively, which were significantly lower than those in the control group [90% (45/50), 30% (15/50), 32% (16/50) and 92% (46/50), χ2 = 6.979, 7.025, 6.534, 6.134, all P < 0.001]. The complete remission rate in the observation group was significantly higher than that in the control group [30% (15/50) vs. 8% (4/50), χ2 = 9.018, P < 0.001]. The traditional Chinese medicine symptom score in the observation group was significantly lower than that in the control group ( t = 6.982, P < 0.05). CD 8+, CD 4+ and CD 3+ levels in the observation group were (25.16 ± 2.87)%, (38.76 ± 4.16)%, (48.83 ± 5.61)%, respectively, and they were (28. 89 ± 4.02)%, (34.10 ± 4.59)%, (41.12 ± 77)%, respectively in the control group. There were significant differences in CD 8+, CD 4+ and CD 3+ levels between the observation and control groups ( t = 6.392, 6.235, 5.983, all P < 0.05). The dosage of recombinant human granulocyte-colony stimulating factor in the observation group was significantly lower than that in the control group [(2 567.34 ± 308.25) μg vs. (3 917.82 ± 411.67) μg, t = 11.258, P < 0.05]. Serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor were (25.53 ± 7.86) ng/L and (278.34 ± 28.74) ng/L, which were significantly higher than those in the control group [(21.30 ± 3.12) ng/L, (204.17 ± 11.98) ng/L, t = 9.136, 8.856, both P < 0.05]. Conclusion:Modified Sijunzi Decoction for the treatment of moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency can decrease the incidence of myelosuppression possibly through increasing serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor and improving the immune function.
