Objective To investigate the effects of cediranib on hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) pathway and proliferation, migration and invasion of liver cancer cells. Methods The hypoxia microenvironment was simulated in vitro, and different doses of cediranib were used to intervene the human hepatoma cell HepG2, MTT assay was used to detect the proliferation of human hepatoma cell HepG2, Transwell chamber assay was used to detect the invasion and migration of human hepatoma cell HepG2, tumor formation in nude mice was used to detect the growth of human hepatoma cell HepG2 in vivo, the angiogenesis of tumor tissue and expression level of HIF-1α/VEGF pathway protein were detected by immunohistochemistry. Results Compared with the control group, the proliferation rate, invasion and migration abilities, and the expression of HIF-1α/VEGF pathway proteins of human hepatoma cell HepG2 were significantly decreased in the different concentration of cediranib treatment group (P<0.05), the tumor volume and microvessel formation of tumor tissues in nude mice were significantly reduced (P<0.05). Conclusion Cediranib may inhibit the proliferation, migration and invasion of liver cancer cells by inhibiting HIF-1α/VEGF signaling pathway.
Objective To investigate the application of enhanced recovery after surgery (ERAS) in da Vinci robotic McKeown surgery for esophageal cancer. Methods Clinical data of patients admitted to the First Hospital of Lanzhou University and undergoing da Vinci robotic McKeown surgery for esophageal cancer from 2017 to 2021 were retrospectively analyzed. According to the treatment, they were divided into two groups, a conventional group and an ERAS group. Patients in the conventional group were treated with the conventional perioperative treatment mode of thoracic surgery, and patients in the ERAS group were treated with accelerated rehabilitation surgical treatment mode. Relevant hospitalization indicators and postoperative complication rates were compared between the two groups. Results Finally 128 patients were collected, including 106 males and 22 females, with an average age of 61.91 years. There were 71 patients in the conventional group and 57 patients in the ERAS group. The postoperative pain index in the ERAS group was significantly lower than that in the conventional group (P<0.05), and the duration of postoperative analgesic pump used in the ERAS group was shorter than that in the conventional group (2.39±0.49 d vs. 3.13±0.63 d, P<0.001). There was no statistical difference in the incidence of postoperative related complications (gastroesophageal reflux, anastomotic stenosis, anastomotic fistula, arrhythmia, recurrent laryngeal nerve injury, chylothorax, anastomosis stomatitis or incisional infection) between the two groups (P>0.05), but the incidence of postoperative lung infection in the ERAS group was statistically lower (12.28% vs. 26.76%, P=0.043), and the volume of postoperative pleural effusion was statistically less compared with the conventional group (P<0.05). In the ERAS group, the surgery time (294.35±15.19 min vs. 322.79±59.09 min, P<0.001), postoperative exhaust time (1.44±0.39 d vs. 1.94±0.43 d, P<0.001), postoperative removal time of nasolasal tube (6.79±0.73 d vs. 8.21±0.86 d, P<0.001), hospital stay (19.88±3.36 d vs. 21.34±3.59 d, P=0.020), hospitalization costs (105 575.28±8 960.75 yuan vs. 137 894.64±19 518.60 yuan, P<0.001) were all lower or shorter than those of the conventional group. Postoperative activity was longer in the ERAS group than that in the conventional group (P<0.05), but there was no statistical difference in preoperative anesthesia time between the two groups (P=0.841). Conclusion The application of ERAS in da Vinci robotic McKeown surgery for esophageal cancer can effectively alleviate the physiological and psychological burden of patients, reduce the occurrence of postoperative related complications, effectively shorten the total hospital stay, save hospitalization costs, and reduce the economic burden of patients and society. Therefore, it can be promoted and applied in the clinic.
ObjectiveTo investigate the effect of multi-sided foramen ultrafine drainage tube with metal support on the formation of thoracic residual cavity after uniportal video-assisted thoracoscopic (VATS) upper lobectomy. MethodsThe clinical data of the patients who underwent uniportal VATS upper lobectomy for lung cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2021 to April 2022 were retrospectively analyzed. According to the type of ultrafine drainage tube used in the surgery, the patients were divided into a test group (using metal-supported multi-sided foramen ultrafine drainage tube) and a control group (using ordinary 12F ultrafine drainage tube). The incidence of postoperative thoracic residual cavity and operation-related data were compared between the two groups. ResultsA total of 200 patients were enrolled, including 126 males and 74 females, with a mean age of 57.52 years. There were 90 patients in the test group, and 110 patients in the control group. The incidence of postoperative thoracic residual cavity in the test group was lower than that in the control group (P=0.045). The differences in the postoperative bedtime, postoperative visual analogue scale, postoperative analgesic pump using time, postoperative hospitalization time, times of postoperative thoracentration and drainage, postoperative drainage time and hospitalization cost between the two groups were statistically significant (P<0.05). The incidences of postoperative lung infection, pleural effusion and atelectasis complications were lower in the test group than those in the control group (P<0.05). The differences in the preoperative anesthesia time, operation time, intraoperative bleeding and postoperative lung leakage were not statistically significant (P>0.05). ConclusionThe use of multi-sided foramen ultrafine drainage tube with metal support can reduce the incidence of thoracic residual cavity after uniportal VATS upper lobectomy, and can reduce pain and economical burdens and the incidence of operation-related complications, accelerating the recovery of patients after surgery. The application of multi-sided foramen ultrafine drainage tube with metal support in uniportal VATS upper lobectomy can be widely used in the clinic.
ObjectiveTo explore the application value of prognostic nutritional index (PNI) in the postoperative complications of McKeown surgery for da Vinci robotic esophageal cancer. MethodsThe clinical data of the patients who underwent da Vinci robotic McKeown surgery for esophageal cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2019 to June 2022 were retrospectively collected. According to the receiver operating characteristic (ROC) curve, the optimal cut-off value of PNI for predicting postoperative complications was explored. The patients were divided into a high PNI group and a low PNI group according to the cut-off value, and the differences in basic characteristics, surgery-related indexes and postoperative complications between the two groups were analyzed. According to the occurrence of postoperative complications, the patients were divided into a non-complication group and a complication group. Univariate and multivariate analyses were used to explore the influence of relevant indicators on the occurrence of postoperative complications in da Vinci robotic McKeown surgery for esophageal cancer. ResultsFinally 120 patients were collected, including 95 males and 25 females, with an average age of 62.82 years. The preoperative hemoglobin content, preoperative blood lymphocyte count, preoperative serum albumin and preoperative blood total cholesterol in the high PNI group were higher than those in the low PNI group (P<0.05). There were statistical differences between the two groups in the incidences of postoperative overall complications, pulmonary infection, pleural effusion and poor incision healing (P<0.05). The relevant indicators that may cause postoperative complications were included in univariate analysis, and the results showed that age, operation time, intraoperative blood loss, preoperative blood lymphocyte count, preoperative hemoglobin content, preoperative blood mononuclear cell count, preoperative blood monocyte count, serum albumin level and PNI were possible influencing factors of postoperative complications after da Vinci robotic McKeown surgery for esophageal cancer. Incorporating these influencing factors into multivariate analysis, the results showed that age, PNI, operation time and intraoperative blood loss were independent influencing factors of postoperative complications. ConclusionPNI has certain predictive value in the postoperative complications of da Vinci robotic McKeown surgery for esophageal cancer. PNI is an independent factor affecting postoperative complications. Improving the level of PNI in esophageal cancer patient before surgery may help reduce the occurrence of postoperative complications.
ObjectiveTo investigate the clinical effect of metal supported multi-sided versus ordinary ultra-fine drainage tube in the uniportal video-assisted thoracic surgery (VATS) lower pulmonary lobectomy. MethodsFrom January 2021 to June 2022, the clinical data of patients who underwent uniportal VATS lower lobectomy in our hospital were retrospectively analyzed. According to the different types of ultra-fine drainage tubes used in the surgery, the patients were divided into an experimental group (using multi-sided hole 10F ultra-fine drainage tubes with metal support) and a control group (using ordinary 12F ultra-fine drainage tubes). The clinical data of the two groups were compared. ResultsA total of 190 patients were enrolled, including 108 males and 82 females. There were 90 patients in the experimental group aged 56.60±10.14 years; and 100 patients in the control group aged 57.07±11.04 years. The incidences of postoperative lung infection and pleural effusion in the experimental group were lower than those in the control group, with statistically significant differences (P<0.05). The postoperative visual analogue scale score, the need to adjust the chest drainage tube after the surgery, the need for chest puncture after the surgery, the time of postoperative chest tube removal, and the hospitalization cost were statistically different (P<0.05). There was no statistical difference in the length of postoperative hospital stay or the incidences of postoperative lung leakage, arrhythmia, and atelectasis complications (P>0.05). ConclusionCompared with the ordinary ultra-fine drainage tubes, multi-sided hole ultra-fine drainage tubes with metal support can reduce the incidences of lung infection and pleural effusion complications after the uniportal VATS lower lobectomy, reduce the pain and economic burden, which can be applied in the uniportal VATS lower lobectomy.
Objective To evaluate the clinical radiological features combined with circulating tumor cells (CTCs) in the diagnosis of invasiveness evaluation of subsolid nodules in lung cancers. Methods Clinical data of 296 patients from the First Hospital of Lanzhou University between February 2019 and February 2021 were retrospectively included. There were 130 males and 166 females with a median age of 62.00 years. Patients were randomly divided into a training set and an internal validation set with a ratio of 3 : 1 by random number table method. The patients were divided into two groups: a preinvasive lesion group (atypical adenomatoid hyperplasia and adenocarcinoma in situ) and an invasive lesion group (microinvasive adenocarcinoma and invasive adenocarcinoma). Independent risk factors were selected by regression analysis of training set and a Nomogram prediction model was constructed. The accuracy and consistency of the model were verified by the receiver operating characteristic curve and calibration curve respectively. Subgroup analysis was conducted on nodules with different diameters to further verify the performance of the model. Specific performance metrics, including sensitivity, specificity, positive predictive value, negative predictive value and accuracy at the threshold were calculated. Results Independent risk factors selected by regression analysis for subsolid nodules were age, CTCs level, nodular nature, lobulation and spiculation. The Nomogram prediction mode provided an area under the curve (AUC) of 0.914 (0.872, 0.956), outperforming clinical radiological features model AUC [0.856 (0.794, 0.917), P=0.003] and CTCs AUC [0.750 (0.675, 0.825), P=0.001] in training set. C-index was 0.914, 0.894 and corrected C-index was 0.902, 0.843 in training set and internal validation set, respectively. The AUC of the prediction model in training set was 0.902 (0.848, 0.955), 0.913 (0.860, 0.966) and 0.873 (0.730, 1.000) for nodule diameter of 5-20 mm, 10-20 mm and 21-30 mm, respectively. Conclusion The prediction model in this study has better diagnostic value, and is more effective in clinical diagnosis of diseases.
