Objective: To explore the clinical value of non-invasive monitoring of cerebral hemodynamics for
evaluating intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in patients with moderate to
severe traumatic brain injury (TBI). Methods: Transcranial Doppler (TCD) was employed to detect the
hemodynamics of bilateral middle cerebral arteries, including systolic blood fl ow velocity (Vp), diastolic
blood fl ow velocity (Vd), average fl ow velocity (Vm), pulsatility index (PI) and resistance index (RI)
in 52 patients with moderate to severe TBI. At the same time, the CPP, ICP and mean arterial blood
pressure (MABP) were monitored. The correlations between hemodynamics and MABP, ICP as well
as CPP were analyzed. Results: The PI and RI were positively related to the ICP (r=0.881, P<0.0001;
r=0.789, P<0.0001). Multiple stepwise regression analysis showed PI was closely associated with ICP
(ICP=-8.593+24.295PI; t=13.216, P<0.0001) and signifi cant correlation was also found between CPP
and PI as well as MABP (CPP=15.596-22.886PI+0.910MABP; F= 76.597, P<0.0001).
Conclusion: Non-invasive monitoring of cerebral hemodynamics by TCD can refl ect the real time
changes in the ICP and CPP and may be used as an effective tool to monitor the ICP and CPP. This
method is non-invasive, safe, cheap, repeatable and applicable in clinical practice.

To perform modal analysis of CT shelter by applying computer simulation technology so as to pro-vide theoretical guidance for CT shelter structure optimization. Based on CAD model, the finite element model of a CT shelter was established with ANSYS simulation platform. Through modal analysis, different-order modal frequency and modal shape of the shelter were computed and the kinetic characteristics were evaluated. Low order modal frequency was kept away from the natural frequency range of chassis system resonance to avoid the overall structure reso-nance; the 3rd and the 4th modal frequency and engine idle speed frequency were very close so that local resonance might occur; road roughness excitation frequency covered the first 6 order modal frequencies and the further vibration-re-ducing measures of CT equipment were suggested. Based on the theories of finite element method and current software platform, modal analysis of shelter structure can be simulated and the results can provide valuable data for the improvement of kinetic characteristics and structure design.

Surgery is so far the most widely used and effective treatment of neoplastic diseases.However,residual tumour cells during surgery remain a major trigger of cancer recurrence and matastasis.Although intraoperative rapid pathological R0 resection can be achieved based on preoperative imageological examination,but for small satellite lesions and the naked eye can not find the error quickly and so often cause pathological presence of residual tumour cells.Thus,quick and accurate identification of residual cancer cells is crucial for prognosis of cancer patients.Indocyanine green (ICG) is a new type of fluorochrome that can stain tumours under the near-infrared fluorescence during surgery,the paper will be reviewed latest developments in the reagent for fluorescence in tumours.

Non-small cell lung cancer(NSCLC) is one of the most common malignancies worldwide. Not only the complex molecular components but also the cellular heterogeneity in NSCLC tissues pose a great barrier for its clinical treatment. Recent years has witnessed the widespread application of single-cell sequencing in the studies regarding tumor heterogeneity. However, the disadvantages of single-cell sequencing technology itself could not be neglected. Spatial transcriptome(ST) technology allows in situ transcriptome sequencing of tissues to achieve high-throughput transcriptomic information of tissue cells with their spatial information available. In other words, ST makes it possible to acquire cellular composition and gene expression patterns without breaking intercellular communication network, which distinguishes itself from conventional single-cell sequencing, since mechanical separation and enzymatic digestion of tissue cells into single-cell suspension used to be inevitable during the performance of single-cell sequencing. To gain new insights into the spatial heterogeneity of NSCLC, we reviewed and summarized the latest progress in ST technology which has been applied to tumor sample analysis, especially to the field of NSCLC.

Objective:To evaluate the effect of transnasal humidified rapid insufflation ventilatory exchange (THRIVE) on regional cerebral oxygen saturation (rScO 2) during induction of general anesthesia in patients undergoing traumatic brain injury (TBI) emergency surgery. Methods:A prospective randomized controlled trial was conducted. The TBI emergency general anesthesia patients who underwent intracranial hematoma removal surgery at the Northern Jiangsu People's Hospital from January to July in 2023 were enrolled. The patients were divided into a conventional mask ventilation group and a THRIVE group using a random number table method. The patients in the conventional mask ventilation group were anesthetized and induced to pre oxygenate without positive pressure ventilation in the front mask for 10 minutes, with an oxygen flow rate of 8 L/min and an fraction of inspired oxygen (FiO 2) of 1.00. After anesthesia induction for about 90 s, tracheal intubation was performed after the muscle relaxant took effect (patient's jaw muscle was relaxed). The patients in the THRIVE group were pre oxygenated with THRIVE for 10 minutes, with an oxygen flow rate of 30 L/min and a FiO 2 of 1.00. During anesthesia induction, the oxygen flow rate was increased to 50 L/min, and anesthesia induction medication was used. The lower jaw of patient was supported with both hands to maintain airway patency, and the patient's mouth was kept closed throughout the process. After the muscle relaxant took effect (the patient's jaw muscle was relaxed), tracheal intubation was performed. At the time of patient entering the operating room, 10 minutes of pre oxygenation, and immediately after successful intubation, rScO 2 was measured on the surgical and non-surgical sides. At the same time, ultrasound was used to measure the cross-sectional area (CSA) of the gastric antrum and arterial blood gas analysis was performed. The partial pressure of end-tidal carbon dioxide (P ETCO 2) during the first mechanical ventilation after successful tracheal intubation, the incidence of hypoxemia [pulse oxygen saturation (SpO 2) < 0.95] during tracheal intubation, as well as prognostic indicators such as the length of intensive care unit (ICU) stay, total length of hospital stay, and Glasgow outcome scale (GOS) score at discharge were recorded. Results:During the study period, a total of 70 TBI patients underwent emergency general anesthesia surgery, of which 2 patients died postoperatively, 2 patients were unable to cooperate with closed mouth breathing, and 3 patients had poor ultrasound image acquisition in the gastric antrum, all of whom were excluded. A total of 63 patients were ultimately enrolled, including 32 in the conventional mask ventilation group and 31 in the THRIVE group. There were no statistically significant differences in gender, age, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, Glasgow coma scale (GCS) score, optic nerve sheath diameter (ONSD), baseline vital signs, fasting situation, anesthesia time, surgical time, and intraoperative blood loss between the patients in the two groups, indicating comparability. When entering the operating room, there was no statistically significant difference in rScO 2 on the surgical and non-surgical sides, and blood gas analysis indexes arterial partial pressure of oxygen (PaO 2) and arterial partial pressure of carbon dioxide (PaCO 2) between the patients in the two groups. When pre oxygenated for 10 minutes, both the surgical and non-surgical sides rScO 2 levels in the THRIVE group were significantly higher than those in the conventional mask ventilation group (surgical side: 0.709±0.036 vs. 0.636±0.028, non-surgical side: 0.791±0.016 vs. 0.712±0.027, both P < 0.01), and the PaO 2 was significantly increased [mmHg (1 mmHg≈0.133 kPa): 450.23±60.99 vs. 264.88±49.33, P < 0.01], PaCO 2 was significantly reduced (mmHg: 37.81±3.65 vs. 43.59±3.76, P < 0.01), and the advantage continues tilled immediately after successful intubation. There was no statistically significant difference in CSA at each time point of ultrasound examination between the two groups. Compared with the conventional mask ventilation group, the patients in the THRIVE group showed a significant decrease in P ETCO 2 during the first mechanical ventilation after successful tracheal intubation (mmHg: 43.10±2.66 vs. 49.22±3.31, P < 0.01), and the incidence of hypoxemia during tracheal intubation was also significantly reduced [0% (0/31) vs. 28.12% (9/32), P < 0.01]. In terms of prognostic indicators, there was no statistically significant difference in the length of ICU stay and total length of hospital stay between the patients in the conventional mask ventilation group and the THRIVE group [length of ICU stay (days): 10 (9, 10) vs. 10 (9, 11), total length of hospital stay (days): 28.00 (26.00, 28.75) vs. 28.00 (27.00, 29.00), both P > 0.05]. However, the proportion of patients in the THRIVE group with a good prognosis at discharge (GOS score > 3) was significantly higher than that in the conventional mask ventilation group [35.5% (11/31) vs. 12.5% (4/32), P < 0.05]. Conclusion:THRIVE can significantly increase rScO 2 during anesthesia induction in TBI emergency surgery patients and improve their neurological function prognosis.
