BACKGROUND:In recent years,computer-assisted navigation has gradually attracted attention in the medical field.Some scholars have reported that the clinical effects of computer navigation in total knee arthroplasty vary.To explore the clinical effect of the new generation of Brainlab Knee 3 navigation system,this study is conducted. OBJECTIVE:To analyze the application effect of computer navigation system(Brainlab Knee 3)combined with gap balance technology in total knee arthroplasty. METHODS:A total of 71 patients received total knee arthroplasty at the Department of Joint Surgery of Dalian Second People's Hospital from November 2020 to May 2021.In the navigation group,35 patients underwent total knee arthroplasty by computer navigation combined with gap balance.In the traditional group,36 patients underwent osteotomy with traditional surgical instruments.The difference between medial and lateral joint spaces,knee range of motion,hospital for special surgery knee score,hip-knee-ankle angle,deviation values of coronal femoral component angle,coronal tibial component angle,and sagittal tibial component angle were compared between the two groups. RESULTS AND CONCLUSION:(1)In the navigation group,the differences of intraoperative medial and lateral joint gap at knee extension 0,1,and 2 mm were found in 19,14,and 2 cases,respectively.The gap difference was 0 mm in 18 cases,1 mm in 15 cases and 2 mm in 2 cases at 90° degree knee flexion.In the traditional group,the gap difference at knee extention was 0 mm in 10 cases,1 mm in 20 cases,and 2 mm in 6 cases.The gap difference at 90 degree knee flexion was 0 mm in 10 cases,1 mm in 15 cases and 2 mm in 8 cases.(2)The operation time in the navigation group was longer than that in the traditional group(P<0.05),and two patients in the navigation group developed lower limb intermuscular vein thrombosis after surgery,and none of the patients in the traditional group had complications.(3)The range of motion between the two groups increased significantly at 6 and 12 months after surgery,and the range of motion in the navigation group was higher than that in the traditional group(P<0.05).(4)At 12 months after surgery,the hospital for special surgery knee scores of both groups increased significantly,and the hospital for special surgery knee score in the navigation group was higher than that in the traditional group(P<0.05).(5)At 6 months after surgery,the deviation values of hip-knee-ankle angle,coronal femoral component angle,coronal tibial component angle,and sagittal tibial component angle of navigation group were significantly lower than those in the traditional group(P<0.05).(6)The results showed that computer navigation technique combined with gap balance in total knee arthroplasty had advantages in postoperative range of motion,lower limb alignment and the accuracy of tibial prosthesis component position,and joint function recovered well.

OBJECTIVE To improve the solubility of the insoluble drug aprepitant, solve the problem of solubilization in acid and crystallization and precipitation in alkali of aprepitant, select polymer carriers with different functions, prepare ternary solid dispersions, and investigate their performance. METHODS Binary solid dispersions were prepared by solvent-melt method, and the solubility and dissolution rate were used as indicators to screen the solubilization-enhancing carrier materials. The crystallization inhibition performance of each polymer in different concentrations of drug solutions was investigated by the medium transfer method, and the best precipitation inhibitor was screened. The ternary solid dispersions were prepared by hot melt extrusion technique, and the ternary solid dispersion prescriptions were preferably selected with the indexes of solubility and crystal inhibition time. The presence of the drug in the carrier was confirmed by X-ray diffraction analysis, and the dynamic solubility and physical stability of the ternary solid dispersion in simulated intestinal fluid under accelerated conditions were investigated. RESULTS The binary solid dispersion prepared by hydrophilic polymer PVP K30 showed fast dissolution and good solubilization, the enterosoluble polymer HPMCAS showed superior crystal inhibition and prolonged the supersaturation point of aprepitant, and the ternary solid dispersion with a mass ratio of 1∶1∶3(APR∶PVP K30∶HPMCAS) was rapidly and completely released in acid(95% dissolution at 120 min). The ternary solid dispersions were completely released and maintained the solution in a highly supersaturated stable state at 6 h when the pH of the medium was shifted to 6.8, which significantly increased the dissolution degree and dissolution rate relative to the APR, and the drug existed in the carrier matrix in an amorphous form, while being able to maintain the amorphous state for at least three months under accelerated conditions. CONCLUSION Based on the physicochemical properties of different polymers, the ternary solid dispersion prepared in this work not only significantly improves the solubility of aprepitant by coordinating the dissolution rate and crystallization inhibition effect, but also solves the problem of aprepitant dissolution in stomach and precipitation in intestine, with good dissolution characteristics.

Objective:To explore the application and clinical efficacy of functional neural navigation multimodal image fusion technology combined with intraoperative fluorescein sodium in the surgery of lung cancer brain metastases.Methods:Forty patients with lung cancer and brain metastasis admitted to the Department of Neurosurgery of Inner Mongolia Autonomous Region People's Hospital from January 2020 to January 2024 were collected as the observation group. Another 40 patients with lung cancer brain metastases who underwent microscopic resection at Inner Mongolia Autonomous Region People's Hospital from January 2016 to December 2019 were selected as the control group. All patients received head CT examination, head MRI examination, MRI enhanced sequence and MRA, MRV and DWI sequence scanning before operation. Functional neural navigation system was used to perform preoperative multi-modal image fusion to realize three-dimensional display of tumor lesions, and display the position relationship between tumor and functional areas, conduction bundles and large blood vessels, so as to make preoperative navigation plan. After conducting a fluorescein sodium allergy test on the patient before surgery, a small dose of fluorescein sodium (2 mg/kg) was intravenously injected during the operation. During the operation, neuro navigation was combined with fluorescein sodium to perform tumor resection by displaying the boundary between tumor tissue and normal brain tissue under a Pentero 900 Zeiss microscope 560 fluorescence mode. Both groups collected tumor tissue samples for pathological classification and immunohistochemical analysis, comparing and analyzing differences in tumor resection degree, postoperative occurrence of new neurological dysfunction, postoperative muscle strength improvement, changes in KPS scores before and after surgery, and the occurrence of complications. The metric data that conforms to normal distribution is represented by xˉ± s, and the comparison of means between two groups is conducted using independent sample t-test. Calculate the percentage based on the count data, and compare the inter group rates using the χ2 test. P<0.05 indicates statistical significance of the difference. Results:Compared with the control group, the total tumor resection rate of observation group (75.0% (30/40) ) and KPS score of 3 months after surgery (82.5% (33/40)) were better than those of the control group (52.5% (21/40) and 60% (24/40)), and the differences were statistically significant ( χ2 value was 4.94 and 4.38, P values were 0.026 and 0.036). The rate of postoperative new neurological dysfunction in the observation group (22.5% (9/40)) was lower than that in the control group (45.0% (18/40)), and the difference between the two groups was statistically significant ( χ2=4.53, P=0.033). The length of hospital stay ((21.48±3.23) days), operation time ((216.65±56.76) points) and complication rate (37.5% (15/40)) in observation group were lower than those in control group ((22.43±2.34) days, (225.62±37.68) points, 45.0% (18/40)). However, the difference was not statistically significant ( t/ χ2 values were 1.51, 0.83, and 0.46, respectively; P values were 0.136, 0.408, and 0.496, respectively). The 12-month survival rate of observation group (67.5%(27/45) respectively was significantly higher than that of control group (40.0%(16/40) respectively, and the difference was statistically significant ( χ2=6.08, P=0.014). Conclusion:Functional neural navigation multimodal image fusion technology combined with intraoperative fluorescein sodium can accurately locate the tumor and determine the boundary relationship between the tumor and normal brain tissue during lung cancer brain metastasis surgery, improve tumor resection rate, enhance patient quality of life, and ultimately improve patient prognosis without increasing the risk of related complications.

Conclusion:Laparoscopic fundoplication combined with gastric suspension for GERD with gastroptosis is safe, effective and worthy of recommendation.

Transient perivascular inflammation of the carotid artery (TIPIC) syndrome is a relatively rare disease, and ultrasound is the first screening method for initial diagnosis of the disease. Contrast-enhanced ultrasound (CEUS) has unique advantages in the follow-up of patients with TIPIC syndrome. This paper reports a patient with TIPIC syndrome who was treated with acute left neck pain. The inflammation was significantly relieved and subsided after treatment with non-steroidal anti-inflammatory drugs. The ultrasound changes of carotid artery lesions in this patient during follow-up were analyzed, and the application value of CEUS in the follow-up diagnosis of this disease was summarized, in the hope of providing clinical reference.

Objective:To investigate the effect of continuous intracranial pressure (ICP) and brain oxygen partial pressure (PbtO 2) monitoring and guiding treatment after the application of standard large bone flap decompression and microhematoma removal in patients with severe traumatic brain injury (TBI). Methods:A retrospective analysis was done of 41 patients with TBI in Department of Neurosurgery in the Inner Mongolia People's Hospital from January 2018 to May 2020. Patients with Glasgow coma scale (GCS)<8 points were treatesd with microscopical removal of hematoma and contusion brain tissue and standard large bone flap decompression. Intraoperative intracranial pressure and brain tissue oxygen partial pressure monitoring probes were placed. Postoperatively, continuous intracranial pressure monitoring and partial oxygen pressure monitoring of brain tissue were performed, and target-based treatment under ICP and PbtO 2 monitoring was performed. According to the Glasgow Outcome (GOS) score after six months, patients were divided into a good outcome group (4-5 scores) and a poor outcome group (1-3 scores). There were 26 cases in good prognosis group and 15 cases in poor prognosis group. Linear regression analysis was used to further evaluate the relationship between PbtO 2, ICP and GOS score. The measurement data of normal distribution were compared by independent sample t-test. The counting data were expressed in cases (%), and the comparison between groups was adopted χ 2 inspection. The general linear bivariate Pearson correlation test was used. Results:The mean value of PbtO 2 (17.42±5.34) mmHg in the poor prognosis group was lower than that in the good prognosis group (24.65±5.61) mmHg, with statistical significance ( t=4.04, P<0.001). The mean value of ICP (22.32±3.45) mmHg in the poor prognosis group was higher than that (17.32±3.23) mmHg in the good prognosis group, with statistical significance ( t=4.15, P<0.001). Using PbtO 2 and ICP as independent variables and GOS score after 6 months as dependent variable, a regression equation was established ( Y=4.040 X+7.497; Y=-2.549 X+28.63). The mean value of PbtO 2 was positively correlated with GOS scores after 6 months in patients with severe head injury ( r=0.75, P<0.001). The mean value of ICP was negatively correlated with the prognosis of patients with severe head injury ( r=-0.87, P<0.001). Conclusion:The treatment guided by ICP combined with PbtO 2 monitoring is valuable in improving the prognosis of patients with severe traumatic brain injury after standard decompressive craniectomy, and may improve the prognosis 6 months after the injury.

Objective:To investigate the effects of continuous monitoring intracranial pressure (ICP) and brain oxygen partial pressure (PbtO 2) on the prognosis of patients with severe craniocerebral injury. Methods:A prospective randomized controlled trial was conducted. Seventy patients with severe craniocerebral injury with a Glasgow coma score (GCS) 4-8 admitted to the neurosurgical intensive care unit (NICU) of the People's Hospital of Inner Mongolia Autonomous Region from January 2017 to May 2020 were enrolled, and they were divided into ICP monitoring group and ICP+PbtO 2 monitoring group by random number table. Patients in ICP monitoring group received ICP monitoring and were given traditional treatment of controlling ICP and cerebral perfusion pressure (CPP), the therapeutic target was ICP < 20 mmHg (1 mmHg = 0.133 kPa) and CPP > 60 mmHg. Patients in ICP+PbtO 2 monitoring group were given ICP and PbtO 2 monitoring at the same time, and oxygen flow was adjusted on the basis of controlling ICP and CPP to maintain the PbtO 2 > 20 mmHg, and the therapeutic target of ICP and CPP was the same as the ICP monitoring group. ICP and PbtO 2 values were recorded during monitoring in the two groups, the results of CPP, GCS and arterial blood gas analysis were recorded, and the prognosis at 3 months and 6 months after injury was compared by Glasgow outcome scale (GOS) score between the two groups. GOS score > 3 was considered as good prognosis. Kaplan-Meier survival curve was drawn, and the 3-month and 6-month cumulative survival rates of the two groups were analyzed. Linear regression analysis was used to further evaluate the relationship between PbtO 2 and GOS score. Results:Finally, a total of 70 patients with severe craniocerebral injury were enrolled in the analysis, 34 patients received ICP combined with PbtO 2 monitoring and guided therapy, and 36 patients received ICP monitoring alone. The average ICP of ICP+PbtO 2 monitoring group was significantly lower than that of ICP monitoring group (mmHg: 13.4±3.2 vs. 18.2±8.3, P < 0.01). Although the CPP in both groups was great than 60 mmHg, the average CPP of ICP+PbtO 2 monitoring group was significantly higher than that of ICP monitoring group (mmHg: 82.1±10.5 vs. 74.5±11.6, P < 0.01). No significant difference was found in average GCS score or arterial partial pressure of carbon dioxide (PaCO 2) between the ICP+PbtO 2 monitoring group and ICP monitoring group [GCS score: 5.3±2.3 vs. 5.2±2.2, PaCO 2 (mmHg): 33.5±4.8 vs. 32.6±5.2, both P > 0.05]. The average arterial partial pressure of oxygen (PaO 2) of ICP+PbtO 2 monitoring group was obviously higher than that of ICP monitoring group (mmHg: 228.4±93.6 vs. 167.3±81.2, P < 0.01). Compared with the ICP monitoring group, the good outcome rates of 3 months and 6 months after injury in the ICP+PbtO 2 monitoring group were significantly higher (3 months: 67.6% vs. 38.9%, 6 months: 70.6% vs. 41.7%, both P < 0.05). Kaplan-Meier survival curve showed that the 3-month and 6-month cumulative survival rates of ICP+PbtO 2 monitoring group were significantly higher than those of ICP monitoring group (3 months: 85.3% vs. 61.1%, Log-Rank test: χ2 = 5.171, P = 0.023; 6 months: 79.4% vs. 55.6%, Log-Rank test: χ2 = 4.511, P = 0.034). Linear regression analysis showed that PbtO 2 was significantly correlated with GOS score at 3 months and 6 months after injury in patients with severe craniocerebral injury ( r values were 0.951 and 0.933, both P < 0.01). Conclusions:PbtO 2 compared with ICP monitoring guiding therapy is valuable in improving the prognosis of patients with severe craniocerebral injury. It can improve the prognosis at 3-6 months after injury.

Objective:To investigate the role of multimodal neuronavigation intraoperative and sodium fluorescein-guided techniques in microsurgery for intracranial malignant neoplasm.Methods:A retrospective analysis was conducted on 50 patients with intracranial malignant tumors treated by microsurgery from 2016 to 2019 in Inner Mongolia People′s Hospital. Preoperative imaging included computed tomography (CT), computed tomographic angiography (CTA), magnetic resonance imaging (MRI), MRI: MRA, MRV, DWI, PWI, DTI, DTI, MRS sequence scan, and before the operation, they were fused with the functional nervous system navigation workstation of Bo Yilai to make the navigation plan. During the operation, the functional navigation was combined with low dose fluorescein sodium (2 mg/kg) for operation. Intraoperative neuronavigation was used to determine the location of the tumor and its spatial relationship with the pyramidal tract of the main fiber conduction tract and the large blood vessels, and intraoperative yellow fluorescence mode of pentero900 Zeiss microscope showed the boundary between the tumor and normal brain tissue for tumor resection.Results:There were 38 cases of glioma, 10 cases of brain metastasis of lung cancer, 1 case of brain metastasis of renal clear cell carcinoma and 1 case of spindle cell tumor. The accuracy of preoperative neuronavigation was 95%. Compared with the preoperative lesions, MRI of the head was reexamined 3 days after operation to judge the degree of tumor resection. In this group, 38 cases (76%) were totally resected and 12 cases (24%) were subtotal resected. The 6-month survival rate was 85.9%, the 12-month survival rate was 53.1%, the 18-month survival rate was 24.5%, and the survival time was (15.0 ± 3.2) months.Conclusion:Multimodal functional neuronavigation combined with fluorescein sodium staining can locate and label tumors in real time, improve tumor resection rate, and improve the prognosis of brain cancer patients.

Objective:To study the application value of six-step cancer notification model (setting, patient's perception, invitation, knowledge, exploring/empathy, strategy/summary, SPIKES) in lung cancer nursing.Methods:The convenience sampling method was used. Forty-two lung cancer patients admitted to the First Affiliated Hospital of Zhengzhou University from June 2017 to June 2018 were selected as control group, and 42 lung cancer patients admitted from July 2018 to July 2019 were selected as observation group.
