Objective:To investigate the current status of application of stereotactic body radiation therapy (SBRT) in China, aiming to provide reference for promoting the development of this technology.Methods:From January to March 2024, a questionnaire was designed and distributed online, targeting member units of the Professional Committee of Stereotactic Radiosurgery Treatment, which covers 175 radiotherapy units in 30 provinces and regions nationwide. The survey focused on the current application of SBRT technology and its utilization in the treatment of early-stage non-small cell lung cancer (NSCLC). A statistical description of the survey results was presented.Results:Of 175 questionnaires distributed, a total of 130 valid responses were collected, with an effective response rate of 74.3%. A total of 81.5% (106/130) of the units had implemented SBRT technology, and 99.1% of the respondents believed it was necessary to further promote SBRT technology, yet the actual training rate was only 67.0%. SBRT equipment configuration: there were a total of 267 SBRT equipment, featuring a diverse range of types, with traditional linear accelerators as the mainstays, accounting for 76.0% ( n=203), followed by 12.0% ( n=32) for TOMO, 6.4% ( n=17) for Cyber knife, 3.7% ( n=10) for Gamma knife, and proton/heavy ion equipment at 1.5% ( n=4), respectively. The percentage of units with multi-leaf collimator leaf widths ≤0.5 cm was 93.4% (99/106). The application of SBRT: the first radiotherapy unit commenced SBRT in 2000, and this technology entered a period of rapid growth after 2015, sustaining a steady increase over the past decade; SBRT technology was mainly applied in the brain, lung, liver, bone, adrenal gland, and kidney, with application rates of 97.2%, 94.3%, 86.8%, 71.7%, 56.6%, and 27.4%, respectively, while the application rates for the pancreas, metastatic lymph nodes, and other parts were less than 5%. Current status of SBRT technology application in early-stage NSCLC: 90.6% (96/106) of units had implemented SBRT; pre-treatment multi-disciplinary diagnosis and treatment accounted for 77% (74/96); the proportion of application units for peripheral and central type lung cancer lesions both exceeded 57.3%, whereas the application rate for ultra-central type and lesions > 5 cm lung cancer was less than 30%; there was significant variability in the selection of reference guidelines, dose fractionation patterns, and the concept of central type among units. Conclusions:The development of SBRT technology in China is in a period of steady growth, but several issues such as low training rate and lack of standardization still exist. The survey results provide important reference for clinical training and promotion of SBRT technology in China.

Objective:To observe the clinical efficacy of Xinyue Decoction combined with fluoxetine hydrochloride in the treatment of cognitive impairment of senile depression.Methods:A randomized controlled trial study was conducted. Totally 116 elderly patients with depression accompanied by cognitive impairment were set as observation subjects, and were divided into a control group and an experimental group using random number table method, with 58 patients in each. The control group received treatment with fluoxetine hydrochloride capsules, while the experimental group was administered Xinyue Decoction Granules in addition to the treatment regimen of the control group. The treatment lasted for 8 weeks for both groups. Comparison was made between the two groups regarding the changes in TCM syndrome scores. Hamilton Depression Scale (HAMD-24) was used to assess the degree of depression, and Montreal Cognitive Assessment (MoCA BJ) was used to assess cognitive ability; the serum levels of brain-derived neurotrophic factor (BDNF), IL-1β, IL-6 and TNF-α were detected by ELISA; the adverse reactions during treatment were observed and recorded, and the clinical efficacy was evaluated.Results:The total effective rate of TCM syndromes was 90.4% (47/52) in the experimental group and 75.5% (40/53) in the control group, with statistical significance ( χ2=4.11, P<0.05); the total effective rate of MoCA-BJ was 76.9% (40/52) in the experimental group and 58.5% (31/53) in the control group, with statistical significance ( χ2=4.61, P<0.05); the total effective rate of HAMD-24 was 88.5% (46/52) in the experimental group and 71.7% (38/53) in the control group, with statistical significance ( χ2=4.07, P<0.05). After treatment, the TCM syndrome score, HAMD-24 and MoCA-BJ scores of the experimental group were lower than those in the control group ( t=-3.51, -5.11, 2.39, P<0.01 or P<0.05); the level of serum BDNF [(10.49±1.76) ng/L vs. (9.61±1.85) ng/L, t=2.28] in the observation group was higher than that of the control group ( P<0.05), and the levels of IL-1β, IL-6 and TNF-α were lower than those in the control group ( t=-2.50, -2.46, -2.18, P<0.05). During the treatment, the incidence of adverse reactions was 5.77% (3/52) in the experimental group and 7.55% (4/53) in the control group, without statistical significance ( χ2=0.13, P>0.05). Conclusion:Xinyue Decoction combined with fluoxetine hydrochloride can reduce the degree of depression in elderly patients with cognitive impairment of depression, improve the cognitive ability of patients and clinical efficacy.

Objective:To observe the expression of adenosine kinase (ADK) in the hippocampus of patients with refractory epilepsy, and to explore the role of ADK in the pathogenesis of refractory epilepsy.Methods:Thirteen patients with intractable epilepsy who underwent surgical resection of hippocampal tissue at the First Affiliated Hospital of Harbin Medical University were collected as the epilepsy group; At the same time, 4 cases of relatively normal temporal lobe brain tissue from patients with traumatic brain injury undergoing debridement surgery (without previous history of epileptic seizures) were collected, and these 4 patients served as the control group. The expression of ADK in two groups of specimens was detected at the tissue, gene, and protein levels using methods such as dual fluorescence immunohistochemistry, real-time quantitative polymerase chain reaction (RT Real time PCR), and Western blotting.Results:In the human brain, ADK was mainly expressed in the nucleus of astrocytes. Through histological observation, ADK was weakly expressed in normal brain tissue, while there is significant proliferation of glial cells and excessive expression of ADK in the brain tissue of patients with refractory epilepsy. The percentage of ADK positive glial cells in the epilepsy group was (53.90±17.59)%, and the control group was (23.82±4.18)%, with a statistically significant difference ( P<0.01). At the genetic level, using RT Real time PCR, it was found that the expression level of ADK mRNA in the epilepsy group was higher than that in the control group, with a 2 -△△Cp of 13.36, which was 13.36 times higher than that in the control group. At the protein level, the expression of ADK protein in the epilepsy group was found to be higher than that in the control group using protein immunoblotting ( P<0.01). Conclusions:ADK is weakly expressed in the nucleus of astrocytes in normal human brain tissue. In the brain tissue of patients with refractory epilepsy, astrocytes significantly proliferate and there is excessive expression of ADK. ADK may play an important role in the occurrence and development of refractory epilepsy in humans.

BACKGROUND:Neural stem cells transplanted into the infarct region can promote the recovery of damaged nerve cells after cerebral infarction.
OBJECTIVE:To analyze the relevant influential factors of neural stem celltransplantation in the treatment of cerebral infarction.
METHODS:In this paper, we analyzed the experimental studies concerning neural stem celltransplantation for cerebral infarction published in recent years based on database search. There were main two aspects for discussing the progress in neural stem cells and cerebral infarction, the Chinese clinical trial registration and basic experimental studies.
RESULTS AND CONCLUSION:After cerebral infarction, neural stem cellproliferation and differentiation is closely related to the brain microenvironment. Large amount of nerve cellloss can be found in the infarct region. Cytokines can play a role in the neural stem celltransplantation to repair neurological injury after cerebral infarction, and also can induce neural stem cellproliferation, differentiation and migration, including epidermal growth factor, brain-derived neurotrophic factor, insulin-like growth factor 1, nerve growth factor, and basic fibroblast growth factor. Acupuncture and traditional Chinese medicine can promote the proliferation, migration and differentiation neural stem cells in the subependymal zone after cerebral infarction. Neural stem celltransplantation in the treatment of cerebral infarction has yielded progress, but there are stil many issues that need to be resolved in the future.

BACKGROUND:The comfortable shoes can absorb or reduce the impact force from the ground. Is the damped system is absent in shoes to relieve the impulse,the feet will be extremely tired,even damage the human knee joint,waist,back and brain. OBJECTIVE:To measure the changes of human plantar pressure by different sole hardness through the measurement system of plantar pressure. DESIGN,TIME AND SETTING:An observation experiment was performed in the Shanghai University of Sport between December 2008 and February 2009.PARTICIPANTS:Six volunteers wearing the experimental designed shoes were recruited from Nanjing Institute of Physical Education.METHODS:Three pairs of experimental shoes weighing 103 g were measured with shore hardness tester,as 51,62 and 69 hardness values. Accordingly they were named soft shoes,medium hardness shoes and hard shoes. The subjects were asked to do a 60-minute walk test at the speed of 2 m/s on the running platform with the experimental designed shoes,and they were determined using the insole plantar pressure measurement system of German's Novel style series of Emed-pedar.MAIN OUTCOME MEASURE:The pressure,contact area and impulse in the sole of foot.RESULTS:With the increase in hardness soles,the pressure of center plantar was shown to move from the medial first metatarsal outwards by turns. Compared with barefoot walking,the trail length of the center plantar was prolonged in subjects with medium hardness shoes and hard shoes,while shortened in subjects with soft shoes. The total pressure when you walked with soft shoes and medium hardness shoes were reduced than barefoot walking,and the pressure of walking phase wearing these two types of shoes were also reduced,while total pressure and walking phase pressure with hard shoes were both increased compared with barefoot walking. The contact area was similar between soft shoes and medium hardness shoes,but the smallest in the hard shoes. Except the increase in the initial 10 minutes,the soft shoes had no change with the medium hardness shoes. The hard shoes were firstly increased but then declined. The total impulse of medium hardness shoes was the closest to bare feet,while that of soft shoes and hard shoes were increased compared with bare foot.CONCLUSION:The plantar pressure was the greatest in the hard shoes,then medium hardness shoes and last soft shoes;the contact area was the greatest in soft shoes,then medium hardness shoes and last hard shoes;the impulse was the greatest in hard shoes,then soft shoes,and last medium hardness shoes.
