A 34-year-old male patient was admitted to the hospital on October 6, 2023 due to fall from a high place. Physical examination showed blood pressure 96/53 mmHg (1 mmHg=0.133 kPa), heart rate of 105 beats/min, slight bulge in the right kidney area, and positive percussion pain in the right kidney area. CT examination showed complete rupture of the lower pole of the right kidney, thrombosis of the right renal vein, and contusion and laceration of the right posterior lobe of the liver. According to the American Association for the Surgery of Trauma renal injury classification, he was diagnosed as grade Ⅳ renal rupture. After blood transfusion and fluid infusion, vital signs were stable. Laparoscopic nephrectomy plus renal vein thrombectomy plus liver rupture repair were performed. The operation took 90 minutes, and about 300 ml of blood clots and fresh blood were aspirated during the operation. The patient's vital signs were stable after the operation, and he could get out of bed 3 days after the operation. CT reexamination 1 month after the operation showed right kidney resected and the liver healed well. This operation is feasible if the patient's vital signs are stable, with the advantages of small surgical incision, short operation time, less bleeding, fast postoperative recovery and good surgical effect.

OBJECTIVE To study the repair effect of ephedrine on lipopolysaccharide （LPS）-induced microglia function injury and its mechanism. METHODS Human microglia cells （HMC3） were used as research objects to investigate the effects of different concentrations of ephedrine （75， 150， 300， 600 μg/mL） on the viability and apoptosis of HMC3 cells. HMC3 cells were divided into control group （without drug intervention）， LPS group （1 μg/mL）， ephedrine group （1 μg/mL LPS+300 μg/mL ephedrine）， BAY11-7082 group [1 μg/mL LPS+5 μmol/L nuclear factor-κB （NF-κB） pathway inhibitor BAY11-7082]， inhibitor group （1 μg/mL LPS+300 μg/mL ephedrine+5 μmol/L BAY11-7082） and activator group （1 μg/mL LPS+300 μg/mL ephedrine+1 μmol/L NF-κB pathway activator Prostratin）. After 24 hours of drug treatment， cell migration， the levels of soluble interleukin-6（sIL-6）， interleukin-10（IL-10）， superoxide dismutase（SOD）and malondialdehyde（MDA）， and the expressions of NF-κB pathway-related proteins were all detected. RESULTS The viability of HMC3 cells could be increased significantly by 300 μg/mL ephedrine， while the apoptotic rate was decreased significantly （P＜0.05）. Compared with the control group， the number of migrating cells was increased significantly in the LPS group； the levels of sIL-6 and MDA， the phosphorylation of NF-κB protein were increased significantly， while the levels of IL-10 and SOD were decreased significantly （P＜0.05）. Compared with the LPS group， the above indexes were reversed significantly in the ephedrine group and BAY11-7082 group （P＜0.05）. Compared with the ephedrine group， the number of migrating cells was decreased significantly in the inhibitor group； the levels of sIL-6 and MDA， the phosphorylation of NF-κB protein were decreased significantly， while the levels of IL-10 and SOD were increased significantly （P＜0.05）. The above indexes were reversed significantly in the activator group （P＜0.05）can repair cell injury by inhibiting LPS induced apoptosis， migration， inflammation and oxidant stress of HMC3 cells， the mechanism of which may be associated with inhibiting the activity of the NF-κB signaling pathway.

Objective To investigate the relationship between the ratio of soluble hemoglobin scavenger receptor 163 protein(sCD163)/soluble tumor necrosis factor-like weak inducer of apoptosis(sTWEAK)in plasma and prognosis in patients with spontaneous acute cerebral hemorrhage(ACH).Methods From August 2020 to August 2022,90 patients with ACH admitted to the Department of Neurosurgery,Harison International Peace Hospital,Hengshui City were regarded as the research group.According to the Glasgow outcome scale,patients with ACH were separated into the poor prognosis group(n=38)and the good prognosis group(n=52).Another 45 healthy examinee who underwent physical examination were used as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect plasma sCD163 and sTWEAK levels,and the sCD163/sTWEAK ratio was calculated.Pearson method was applied to analyze the correlation between plasma sCD163,sTWEAK levels,sCD163/sTWEAK ratio and clinical data.Logistic regression was applied to analyze influencing factors of poor prognosis in patients with ACH.Receiver operating characteristic(ROC)was applied to analyze the predictive value of sCD163/sTWEAK ratio for poor prognosis of patients with ACH.Results The plasma levels of sCD163,sTWEAK and sCD163/sTWEAK ratio were obviously higher in the research group than those in the control group(P＜0.05).The plasma levels of sCD163,sTWEAK and sCD163/sTWEAK ratio were obviously lower in the good prognosis group than those in the poor prognosis group(P＜0.05).Hematoma volume,National Institutes of Health Stroke Scale(NIHSS)scores,hypertension and subtentorial hemorrhage were lower in the good prognosis group than those in the poor prognosis group,and low density lipoprotein cholesterol(LDL-C)was higher in the good prognosis group than that in the poor prognosis group(P＜0.05).Correlation analysis showed that plasma sCD163,and sTWEAK levels and the sCD163/sTWEAK ratio were positively correlated with bleeding site,hematoma volume,NIHSS score,white blood cell count,platelet count and neutrophil/lymphocyte ratio(NLR)(P＜0.05).Results of Logistic regression analysis showed that sCD163,sTWEAK,sCD163/sTWEAK ratio,hematoma volume,bleeding site and NIHSS score were influencing factors for poor prognosis in patients with ACH(P＜0.05).Results of receiver operating characteristic showed that the AUC of sCD163/sTWEAK ratio in evaluating poor prognosis of patients with ACH was 0.850,and the sensitivity and specificity were 86.84%and 69.23%.Conclusion The sCD163/sTWEAK ratio has a high level in the plasma of patients with ACH,which is associated with poor prognosis and has important value in predicting the prognosis of patients with ACH.

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.

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 influence of bundled ligation of the pancreatic stump on postoperative pancreatic fistula (POPF) of distal pancreatectomy (DP).Methods:The retrospective case-control study was conducted. The clinical data of 60 patients with diseases in pancreatic body and tail who underwent DP in the Affiliated Hospital of Inner Mongolia Medical University from January 2011 to August 2018 were collected. There were 24 males and 36 females, aged from 19 to 68 years, with a median age of 45 years. Of the 60 patients, 36 cases undergoing dissection of pancreas with Endo-GIA stapler were allocated into non-bundled group, and 24 cases undergoing bundled ligation of the pancreatic stump with No.10 or No.7 suture at the site over 1 cm of the resection site before dissection of pancreas were allocated into bundled group. Observation indicators: (1) postoperative situations; (2) analysis of risk factors for POPF of DP. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test or ANOVA test. Measurement data with skewed distribution were represented as M (range).Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the chi-square test and multivariate analysis was conducted using the Logistic regression model. Results:(1) Postoperative situations: the amylase concentration, cases with biochemical fistula, cases with grade B pancreatic fistula, cases with complications, time to extubation, duration of postoperative hospital stay, total hospital expenses were (2 629±592)U/L, 14, 5, 7, (11.9±0.7)days, (13.6±0.7)days, (49 430±1 626)yuan in non-bundled group and (683±312)U/L, 3, 1, 2, (9.7±0.6)days, (11.3±0.5)days, (44 767±1 163)yuan in bundled group, respectively. There were significant differences in the amylase concentration, cases with biochemical fistula, time to extubation, duration of hospital stay, total hospital expenses between the two groups ( t=2.528, χ2=1.512, t=2.341, 2.311, 2.111, P<0.05), and there was no significant difference in the cases with grade B pancreatic fistula or cases with complications between the two groups ( χ2=1.512, 1.394, P>0.05). (2) Analysis of risk factors for POPF of DP. Results of univariate analysis showed that tumor diameter and bundled ligation of the pancreatic stump were related factors of patients undergoing pancreatic fistula after DP ( χ2=4.462, 5.061, P<0.05). Results of multivariate analysis showed that bundled ligation of the pancreatic stump was an independent influencing factor of patients undergoing pancreatic fistula after DP ( odds ratio=0.187, 95% confidence interval as 0.037-0.954, P<0.05). Conclusions:Bundled ligation of the pancreatic stump was an independent influencing factor of patients undergoing pancreatic fistula after DP. Bundled ligation of the pancreatic stump can effectively reduce the incidence of POPF, especially biochemical fistula, the time to extubation, duration of postoperative hospital stay and total hospital expenses, and promote patient recovery after DP.

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.
