Glioblastoma（GBM）is the most common and malignant brain tumor in adults. The subventricular zone（SVZ）, as the most concentrated site of adult neural stem cells, may be the potential source of glioblastoma stem cells. Studies have shown that SVZ plays an important role in the occurrence, development, recurrence and metastasis of the disease, and SVZ involvement can be used as a adverse prognostic marker in GBM patients. Therefore, SVZ may be a target for radiotherapy in patients with GBM. Moreover, SVZ radiotherapy can improve the prognosis of GBM, but there have been many contradictory research results in recent years. In order to explore the clinical value of SVZ, it is necessary to discuss the latest research progress between SVZ and radiotherapy. This review summarizes the relevant theoretical basis research, lists and evaluates the existing clinical evidence, and explores the value of SVZ radiotherapy. [ABSTRACT FROM AUTHOR]

BACKGROUND: Platelet-rich plasma can promote the repair and regeneration of intervertebral disc tissue. Percutaneous transforaminal endoscopic discectomy is widely used in the treatment of lumbar disc herniation. In recent years, more and more scholars have focused on the combined treatment of lumbar disc herniation with the two techniques in order to achieve a better patient prognosis. OBJECTIVE: To investigate the clinical safety and effectiveness of percutaneous transforaminal endoscopic discectomy combined with platelet-rich plasma in the treatment of lumbar disc herniation. METHODS: The clinical data of 58 patients with lumbar disc herniation who met the inclusion and exclusion criteria at Sixth Medical Center of PLA General Hospital from June 2017 to May 2018 were retrospectively analyzed. Among them, 29 patients underwent percutaneous transforaminal endoscopic discectomy combined with platelet-rich plasma (observation group), and the remaining 29 patients underwent percutaneous transforaminal endoscopic discectomy only (control group). Visual Analogue Scale score for back and leg pain, lumbar JOA score, and Oswestry Disability Index were evaluated preoperatively, at 3, 6, and 12 months postoperatively, and at the last follow-up. Intervertebral space height, nucleus pulposus to cerebrospinal fluid signal strength ratio, and intervertebral disc Pfirrmann grading were measured preoperatively, at 6 and 12 months postoperatively, and at the last follow-up. The modified MacNab criteria were used to assess excellent and good rate of curative effect at the last follow-up. RESULTS AND CONCLUSION: (1) The Visual Analogue Scale score for back and leg pain, JOA score, and Oswestry Disability Index of the two groups postoperatively were significantly improved compared with those preoperatively (P < 0.05). Visual Analogue Scale score and Oswestry Disability Index were lower in the observation group than those in the control group at 3 and 6 months postoperatively (P < 0.05). The JOA score was higher in the observation group than that in the control group at 3 and 6 months postoperatively (P < 0.05). (2) The nucleus pulposus to cerebrospinal fluid signal strength ratio was higher in the observation group than that in the control group at the last follow-up (P < 0.05). Pfirrmann grading of the intervertebral discs was better in the observation group than that in the control group (P < 0.05). The excellent and good rate was 93% in the observation group and 83% in the control group, and the difference was not statistically significant (P > 0.05). (3) These findings indicate that percutaneous transforaminal endoscopic discectomy combined with platelet-rich plasma in the treatment of lumbar disc herniation has satisfactory clinical efficacy and can delay the degeneration of the intervertebral disc to a certain extent.

Objective To observe the efficacy and safety of radiotherapy combined with programmed death receptor ⁃ 1（PD ⁃ 1） inhibitors and tyrosine kinase inhibitors （TKIs） for the treatment of microsatellite-stabilized （MSS) ⁃type or mismatch⁃matched repair⁃normal （pMMR) ⁃type colorectal cancer with liver metastases （CCLM）. Methods Case data of 25 patients with MSS⁃type CCLM admitted to Jiangsu Provincial Cancer Hospital from April 2021 to August 2023 were retrospectively analyzed. They were divided into observation group （n = 12） and control group （n = 13）. The observation group was given radiotherapy combined with PD⁃1 inhibitor and TKI treatment, and the control group was given TKI monotherapy. The baseline data， treatment effect, progression⁃free survival, and treatment⁃related adverse reactions of patients in the two groups were compared. Results The difference in baseline data between the two groups was not statistically significant （P > 0.05), the disease control rate （DCR） of the observation group was higher than that of the control group （P < 0.05）， the progression⁃free survival （PFS） of the patients in the observation group was longer than that of the control group, but the difference was not statistically significant （P > 0.05), and the difference in the incidence of treatment⁃related adverse events （TRAE） between the two groups was not statistically significant （P > 0.05）. Conclusion The treatment regimen of radiotherapy combined with PD⁃1 inhibitors and TKI drugs improved clinical efficacy and did not increase the incidence of adverse events when compared with TKI alone， which is a treatment regimen worthy of further validation.

Objective To observe the effects of enhanced external counterpulsation on reninangiotensin aldosterone system (RAAS), carotid artery structure and hemodynamics, homocysteine (Hey), lipoprotein associated phospholipase A2(Lp-PLA2), high sensitivity C-reactive protein (hs-CRP) and blood lipids in elderly patients with essential hypertension and increased resting heart rate. Methods A total of 150 elderly patients with primary hypertension and elevated resting heart rate were randomly divided into two groups. The control group (75 cases) received lifestyle intervention and treatment with bisoprolol fumarate, while the observation group (75 cases) received enhanced extemal counterpulsation therapy in addition to the control group's treatment. The duration of treatment was 12 weeks. Before and after treatment, plasma RAAS indicators, including plasma renin (PRA), angiotensin II (Ang II), and aldosterone (ALD) levels, as well as carotid ultrasound parameters such as intima media thickness (IMT), diastolic diameter (Dd), pulsatility index (PI), resistance index (RI), end diastolic velocity (EDV), peak systolic velocity (PSV), and maximum shear rate (SR) were compared. Lipid profiles, Hey, Lp-PLA2, hs-CRP levels, blood pressure, and heart rate changes were also assessed. Results In the observation group, 24 hour average systolic blood pressure (24hmSBP), 24-hour average diastolic blood pressure (24hmDBP), daytime heart rate (dHR), nighttime heart rate (nHR), 24-hour heart rate (24hHR), Ang II, ALD, PRA, hs-CRP, Hey, Lp-PLA2, total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) levels, as well as carotid IMT, PI, RI, and Dd were all lower than those in the control group (all P<0.05). Carotid EDV, PSV, and SR were higher in the observation group than those in the control group (all P<0.05). Conclusion Enhanced external counterpulsation therapy for elderly patients with primary hypertension and elevated resting heart rate effectively inhibits the activation of the RAAS system, improves carotid atherosclerosis and hemodynamics, suppresses inflammatory response, and regulates lipid and Hey metabolism.

Objective To explore the clinical efficacy of preoperative precise rehabilitation on endoscopic spinal decompression （Endo-LOVE） for lumbar spinal stenosis （LSS）. Methods A retrospective study was con⁃ ducted among 52 patients with Endo-LOVE from January 2020 to April 2022. The patients were equally divided into observation group and control group, treated with precision rehabilitation and traditional rehabilitation accord⁃ ing to the different rehabilitation patterns, respectively. The two groups were compared in terms of the score by Visual Analogue Scale （VAS）, Oswestry Disability Index （ODI） and JOA scores as well as the ratio of left and right supporting phases in gait parameters before the operation, 7 days and 3 months after the operation. Results There were no serious surgical complications in all patients. The VAS and ODI scores 7 days and 3 months after the operation were significantly lower （P < 0.05） and the JOA score and the ratio of left and right supporting phases were significantly higher than before the operation（P < 0.05）. The indexes of the observation group were statisti⁃ cally significantly different with those of the control group 7 days and 3 months after the operation （P < 0.05）. Conclusion Preoperative precise rehabilitation in Endo-LOVE for LSS can relieve postoperative residual pain, improve walking function, reduce the degree of lumbar dysfunction, improve the ability of daily living, and shorten the rehabilitation period. It is of value for clinical application. [ABSTRACT FROM AUTHOR]

In order to solve the simple application of interlaminar or intervertebral foramen approach, there is often incomplete decompression for cases of lumbar spinal stenosis caused by multiple sites, multiple factors and multiple layers. By establishing the finite element model M0 of human lumbar L4-L5 segment, an accurate lumbar simulation model was used to investigate simulate the decompression of interlaminar combined with intervertebral foramen approach, that is, the M3 model of periarticular decompression formed by Endo-LOVE combined with PTED. The biomechanical changes and the stability of the responsible segment after the treatment of lumbar spinal stenosis by interlaminar combined with intervertebral foramen approach were studied. The results show that when M3 was in flexion, extension, left bending, right bending, left rotation and right rotation, the activity of L4-L5 responsibility segment increased by 7. 28%, 11. 29%, 0. 51%, 0. 27%, 1. 17% and 0. 51% respectively compared with M0, and no segment instability occurred. When M3 was under six different conditions of flexion, extension, left bending, right bending, left rotation and right rotation, the Von Mises stress extremum of the intervertebral disc increased by 3. 20%, 9. 51%, 0. 55%, 0. 10%, 0. 39% and - 0. 44% respectively compared with M0, and no stress mutation occurred. It is concluded that in the treatment of lumbar spinal stenosis by endoscopic interlaminar combined with intervertebral foramen decompression, the ROM value of the responsible segment and the extreme value of Von Mises stress of the intervertebral disc are not significantly increased compared with the normal L4-L5 segment, and the biomechanical stability is good. It can expand the spinal canal volume and fully decompress under the condition of retaining the facet joint, and effectively maintain the stability of the responsible segment. [ABSTRACT FROM AUTHOR]

BACKGROUND: Immune mechanism plays an important role in the occurrence and development of lumbar discogenic neuralgia. Platelet-rich plasma is one of the effective means for the treatment of lumbar degenerative diseases such as lumbar discogenic neuralgia. Exploring the expression of immune complex of lumbar discogenic neuralgia and the therapeutic mechanism of platelet-rich plasma can provide new ideas for the prevention and timely treatment of neuralgia secondary to disc degeneration. OBJECTIVE: To review the immune mechanism of lumbar discogenic neuralgia and the therapeutic mechanism of platelet-rich plasma, and make a prospect. METHODS: PubMed database, CNKI database and VIP database were searched. The English and Chinese search terms were “disc degeneration, lumbar discogenic neuralgia, lumbar discogenic sciatica, sciatica, PRP, platelet rich plasma, immunological response”. After preliminary screening of all articles according to inclusion and exclusion criteria, 86 articles were finally included for review. RESULTS AND CONCLUSION: The role of immune mechanism in lumbar intervertebral disc degeneration has been extensively studied, and it plays a key role in the generation and development of lumbar discogenic neuralgia. Various immune inflammatory factors are the key mediators leading to nerve root pain. The treatment of lumbar discogenic neuralgia by platelet-rich plasma is mainly based on its rich growth factors, including anti-inflammatory and neuroprotection, immunomodulation, Schwann cell activation and axon regeneration, intervertebral disc degeneration repairing and angiogenesis.

Since the global outbreak of COVID-19 the virus has continued to mutate and its immune escape transmission and other capabilities have increased on January 30 2023 the WHO committee unanimously concluded that COVID-19 remains a dangerous infectious disease with the ability to cause significant damage to human health and health systems. Therefore wearing medical protective clothing as an effective form of personal protection plays an extremely important role in personal protection. However the research and development of medical protective clothing in China started late and there is not only the problem of mismatch between application scenarios and product functions but also most research and development are conducted from the perspective of professional medical personnel. In addition consumers apply medical protective clothing in a richer and more diverse scenario and the post-purchase evaluation of consumers can not only reflect their demand for medical protective clothing and influence other consumers purchase decisions on medical protective clothing but also serve as an important basis for relevant enterprises to consider developing and improving their marketing strategies. To deeply understand current consumers view and demand for medical protective clothing this paper based on the collected content of 11 513 consumer reviews of 14 Chinese medical protective clothing brands carried out keyword frequency analysis sentiment analysis network analysis and co-occurrence network analysis accurately revealing the consumers shopping experience perception and demand. The study shows that product quality and express efficiency are the most important factors influencing consumers post-purchase evaluation followed by merchant services and application scenarios while affordable price only plays an important role in positive evaluation product quality and packaging are of great concern to consumers in the positive evaluation consumers are quite content with product quality workmanship material size comfort breathability product packaging and gifts express efficiency delivery and logistics speed price cheap price and merchant service customer service staff service attitude and service response speed . The consumers also express the need to buy medical protective clothing for timely and safe protection in daily life during the epidemic and in scenarios such as air travel. In the negative evaluation consumers dissatisfaction is mainly focused on product quality express efficiency and merchant service such as poor product quality the clothing is too large to be worn the product and related gifts are broken when received and the product material is thin poor express efficiency slow delivery and logistics after the product is ordered and poor merchant service poor customer service attitude no timely response to information omission of products slow invoicing and difficulty to refund . This exploratory study provides new research ideas for consumer experience and valuable reference for the marketing management practices of medical protective clothing enterprises. This study provides valuable reference information for medical protective clothing companies􀆶 product and service improvement logistics partner selection product design and development and price marketing strategies by digging deeper into the content of medical protective clothing consumer reviews and outlining more clearly the concerns of consumers in the process of purchasing medical protective clothing.

techniques for posterior spinal endoscopic treatment of lumbar spinal stenosis, have good clinical efficacy. However, there are few reports on biomechanical and finite element analysis. OBJECTIVE: To study the influence of endoscopic LOVE decompression and endoscopic unilateral laminotomy for bilateral decompression on the biomechanics of endoscopic treatment of lumbar spinal stenosis, and verify the reliability and effectiveness of the two surgical methods in the treatment of lumbar spinal stenosis. METHODS: The CT image of one volunteer was taken. The finite element model M0 of lumbar L4-L5 segment was established by Mimics, Geomagic, Solidworks and Ansys software. On this basis, an endoscopic LOVE decompression model M1 and an endoscopic unilateral laminotomy for bilateral decompression model M2 were established. The same stress was applied to the upper surface of L4 vertebral body of the three groups of models. The lower surface of L5 vertebral body was fixed and supported. The total range of motion and the Von Mises stress extreme value of the annulus fibrosus were analyzed under six physiological conditions of forward bending, extension, left bending, right bending, left rotation, and right rotation. RESULTS AND CONCLUSION: (1) Compared with model M0, the overall joint range of motion of model M1 increased by 8.24%, 12.17%, 0.77%, 1.60%, 1.86%, and 6.85% in forward bending, extension, left bending, left rotation, right bending, and right rotation, respectively; the overall joint range of motion of the model M2 increased by 8.24%, 12.17%, 0.77%, 1.60%, 2.17%, and 6.85% in forward bending, extension, left bending, left rotation, right bending, and right rotation, respectively. Compared with the model M1, the overall joint range of motion of the model M2 under the right bending slightly increased, and there was no obvious increase or trend change in the other working conditions. (2) Compared with model M0, the extreme values of Von Mises stress of the annulus fibrosus in model M1 under forward bending, extension, left bending, left rotation, right bending, and right rotation increased by 4.65%, 16.09%, 0.21%, 0.77%, 0.25%, 1.51%, respectively; the extreme values of Von Mises stress of the annulus fibrosus under forward bending, extension, left bending, left rotation, right bending, and right rotation of model M2 increased by 4.58%, 16.15%, 0.20%, 0.80%, 0.23%, and 1.52%, respectively. The variation trends of the extreme value of Von Mises stress of the fibrous annulus of model M1 and model M2 were not obvious under different working conditions. (3) These results confirm that responsibility segment is stable after endoscopic LOVE decompression and endoscopic unilateral laminotomy for bilateral decompression for treatment of lumbar spinal stenosis.
