BACKGROUND: Tumor-adopted immunity and gene transduction technique are used to introduce tumor necrosis factor-α vector into carrier cells, which are then re-infused into the body so that cancer cells can be killed by tumor necrosis factor-α more directly and effectively with fewer side effects on the other tissues due to high local expression.OBJECTIVE: To study the bioactivity of in vitro cultured tumor necrosis factor-α transduced tumor-infiltrating lymphocytes as well as the inhibitory effects on cancer cells of cancer-loaded rats infused in different ways.DESIGN: A randomized controlled study based on experimental animals.SEETING: Cancer Research Institute of China Medical University.MATERIALS: This study was carried out at the Cancer Research Institute and the Experimental Animal Department, China Medical University,between January 2000 and December 2001. TJ8510 cell line (human brain glioblastoma cell line) was provided by the Neurological Research Institute of Tianjin Medical University Affiliated Hospital. The experimental animals were 36 BALB/C nude mice congenitally having no thymius.METHODS: Based on the establishment of tumor necrosis factor-α retroviral transduction system and the preparation of cartier cells tumor-infil-trating lymphocytes, the monoclonal virus cell line PLC-2 and PLJC-5available were used to introduce marked gene NeoR and targeted gene tumor necrosis factor-α into tumor-infiltrating lymphocytes, respectively.Then cell proliferation, tumor necrosis factor expression and in vitro antitumor activity were examined. After cancer cell inoculation, the 36 nude mice were randomly divided into 6 groups: local infusion control group, local tumor-infiltrating lymphocytes infusion group, local tumor necrosis factor-tumor-infiltrating lymphocytes infusion group, venous infusion control group, venous tumor-infiltrating lymphocytes infusion group and venous tumor necrosis factor-tumor-infiltrating lymphocytes infusion group, and the therapeutic effects on the cancer-loaded mice were observed.proliferation and tumor necrosis factor-α expression in tumor-infiltrating oR-tumor-infiltrating lymphocytes and tumor necrosis factor-tumor-infiltrating lymphocytes was not significantly different from each other (P > 0.05).NeoR-tumor-infiltrating lymphocytes, though not significantly different (P >0.05), significantly differ from that of tumor necrosis factor-tumor-infiltrating lymphocytes (P < 0.01); moreover, tumor necrosis factor-tumor-infiltrating lymphocytes were found to express higher tumor necrosis factor-α conactivity did not significantly differ between tumor-infiltrating lymphocytes and NeoR-tumor-infiltrating lymphocytes (P > 0.05), but obviously increased come of the animal experiment: 40 days after tumor necrosis factor-tumorinfiltrating lymphocytes infusion, cancer size in local tumor necrosis factortumor-infiltrating lymphocytes infusion group was found smaller than that in local infusion control group [(307±42) and (2 048±278) mm3, P < 0.01],and it was also smaller in venous tumor necrosis factor-tumor-infiltrating lymphocytes infusion group than that in venous control group [(954±195)and (1 989±305) mm3 , P < 0.05].CONCLUSION: Tumor necrosis factor-α gene transduced tumor-infiltrating lymphocytes could effectively express tumor necrosis factor, exerting higher and in vivo anti-tumor effects than tumor-infiltrating lymphocytes in cancer-loaded nude mice. No obvious inhibitory effects on the growth of subcutaneous solid carcinoma could be observed in nude mice after venous infusion of human brain glioblastoma tumor-infiltrating lymphocytes, but the inhibitory effects became obvious due to venous infusion of tumor necrosis factor-tumor-infiltrating lymphocytes and significant due to local tumor necrosis factor-tumor-infiltrating lymphocytes infusion, indicating that local infusion is the preferable way in the treatment of glioblastoma by immuno-gene therapy.

Objective To study the HLA match rate of 222 living-related donors for kidney transplantation, and to give suggestions for clinical selection of suitable donors and recipients. Methods We analyzed the HLA match rate of 222 kidney transplantations from living relative donors from April 2006 to December 2008. There were 168 male recipients and 54 female recipients. The ages of 222 recipients ranged from 10 to 58. There were 133 male donors and 89 female donors. The ages of 222 recipients ranged from 21 to 64.Results The HLA-A, B, DR, DR, antigens of 87 kidney transplantations from living parental donors were half-matched, of which 14 were higher than half-matched. The HLA-A, B, DR, DQ antigens of 7 kidney transplantations from living children donors were half-matched, including 2 cases higher than half-matched.Among 56 kidney transplantations from living sibling donors, 12 cases were totally mated, 34 cases were half-matched, and the rest were less than half-matched or mismatched. Among 72 kidney transplantations from other living relative donors, 20 cases were higher than half-matched and 5 cases were completely mismatched. More than 4 HLA antigens in 6 cases were matched, but not half-matched. Three HLA antigens or less were matched in 41 cases. Conclusion The HLA match rates from living parental, children, or sibling donors were higher than other relative donors.

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 effect of placenta previa attached to cesarean scar for adverse pregnant outcomes in patients with or without placenta accreta spectrum disorders (PAS).Methods:The clinical information of patients with cesarean section history and placenta previa during the perioperative period at Peking University First Hospital from January 1st, 2015 to December 31st, 2020 were collected retrospectively. There were 53 cases without PAS and 172 cases with PAS, 153 cases with abnormally invasive placenta (containing placenta increta and placenta percreta) and 72 cases without PAS or with placenta accreta. The pregnant outcomes including rate of postpartum hemorrhage, transfusion, hysterectomy between the above groups were compared. Multivariate analysis was performed to study the factors significantly associated with PAS.Results:Pregnant women with PAS were at higher risk of adverse pregnant outcomes than those without PAS. Patients with PAS had higher incidences of hysterectomy [12.2% (21/172) vs 0(0/53); P=0.005], postpartum hemorrhage [60.5% (104/172) vs 5.7% (3/53); P<0.01] and blood transfusion [66.9% (115/172) vs 7.5% (4/53); P<0.01]. In the subgroup analysis stratified by the type of PAS, patients with abnormally invasive placenta were at higher risk of hysterectomy [13.7% (21/153) vs 0 (0/72); P<0.01], postpartum hemorrhage [66.7% (102/153) vs 6.9% (5/72); χ2 =70.873, P<0.01] and blood transfusion [74.5% (114/153) vs 6.9% (5/72); χ2 =90.869, P<0.01]. After multiple logistic regression, the type of creta had the positive relation with postpartum hemorrhage ( OR=27.622, 95% CI:9.873~77.280; P<0.01) and blood transfusion ( OR=36.912, 95% CI:13.239~102.922; P<0.01). There were no significant correlations between adverse pregnant outcomes and the type of placenta previa or the times of cesarean section (all P>0.01). Conclusions:Placenta previa attached to cesarean scar without PAS or with placenta accreta could not act as the factor of predicting adverse pregnant outcomes in clinic. Placenta previa attached to cesarean scar with placenta increta or placenta percreta could increase the risk of adverse pregnant outcomes.

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 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 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 rapidly evaluate the level of healthcare resource demand for laboratory testing and prevention and control of corona virus disease 2019 (COVID-19) in different epidemic situation, and prepare for the capacity planning, stockpile distribution, and funding raising for infectious disease epidemic response.Methods:An susceptible, exposed, infectious, removed infectious disease dynamics model with confirmed asymptomatic infection cases and symptomatic hospitalized patients was introduced to simulate different COVID-19 epidemic situation and predict the numbers of hospitalized or isolated patients, and based on the current COVID-19 prevention and control measures in China, the demands of resources for laboratory testing and prevention and control of COVID-19 were evaluated.Results:When community or local transmission or outbreaks occur and total population nucleic acid testing is implemented, the need for human resources is 3.3-89.1 times higher than the reserved, and the current resources of medical personal protective equipment and instruments can meet the need. The surge in asymptomatic infections can also increase the human resource demand for laboratory testing and pose challenge to the prevention and control of the disease. When vaccine protection coverage reach ≥50%, appropriate adjustment of the prevention and control measures can reduce the need for laboratory and human resources.Conclusions:There is a great need in our country to reserve the human resources for laboratory testing and disease prevention and control for the response of the possible epidemic of COVID-19. Challenges to human resources resulted from total population nucleic acid testing and its necessity need to be considered. Conducting non-pharmaceutical interventions and encouraging more people to be vaccinated can mitigate the shock on healthcare resource demand in COVID-19 prevention and control.
