BACKGROUND:In clinical application,the therapeutic effect of transcranial magnetic stimulation depends on the ability to accurately target the areas of the brain that need to be stimulated.In recent years,with the development of neuronavigation systems,mobile augmented reality technology,and the new methods of processing magnetic resonance imaging(MRI)data,the accuracy of stimulus target localization and the optimization of target selection are expected to improve further. OBJECTIVE:To review the principle of MRI-based image navigation and its application in transcranial magnetic stimulation and summarize the roles of different modal MRI data analyses in guiding the selection of target areas for transcranial magnetic stimulation. METHODS:An online computer search for relevant literature was performed in PubMed,CNKI database and WanFang database,with the keywords"transcranial magnetic stimulation,coil positioning,neuronavigation,augmented reality,magnetic resonance,theory."Finally,63 documents were included for review. RESULTS AND CONCLUSION:Among the traditional methods of positioning transcranial magnetic stimulation coils,the"5 cm rule"and the international electroencephalogram 10-20 positioning method are the most commonly used.These methods have the advantages of simplicity and economy,but they rely too much on the operator's experience and there were technical differences between operators.The neuronavigation system,which is based on stereotactic technology,is the guiding method for positioning transcranial magnetic stimulation coils with the highest visual degree and accuracy.It achieves visual positioning through MRI data acquisition,3D brain reconstruction,head model registration and stereogeometric positioning.It has high application value in clinical treatment and scientific research,but it cannot be promoted in medical institutions due to its high cost.For various medical institutions,mobile augmented reality is a cost-effective and efficient alternative to the neuronavigation system,which achieves visual positioning of brain tissue under the scalp through MRI data acquisition,2D/3D image construction,virtual image and real brain image superposition.It has the advantages of directly visualization and low cost,and is expected to be popularized and applied in primary medical units.Although the superiority of clinical efficacy of visual coil positioning over the electroencephalogram 10-20 localization strategy has not yet been fully demonstrated,with the progress of brain MRI data analysis,visual positioning is expected to further optimize the target selection strategy of transcranial magnetic stimulation therapy and to improve the response rate and individuation degree of transcranial magnetic stimulation treatment.This is a promising and challenging research direction in the future.

Objective: To investigate the incidence trend of diabetes among children and adolescents in Ningbo City, Zhejiang Province from 2011 to 2021, so as to provide the basis for the prevention and control of diabetes among children and adolescents. Methods: Data on diabetes incidence among children and adolescents aged 0 to 18 years in Ningbo City were collected through the Diabetes Monitoring Platform of the Ningbo Chronic Disease Collaborative Management System from 2011 to 2021. Crude incidence rates were calculated and standardized using data from the Sixth National Population Census in 2010. The trend of incidence rates were analyzed by average annual percent change (AAPC). Results: A total of 701 cases of diabetes among children and adolescents were reported in Ningbo City from 2011 to 2021. The crude and standardized incidence rates were 6.86/105 and 7.27/105, respectively, showing upward trends (AAPC=5.886%, 7.147%, both P<0.05). The crude and standardized incidence rates of type 1 diabetes mellitus were 3.36/105 and 3.35/105, respectively, with no significant trend observed (AAPC=1.229%, 1.449%, both P>0.05). The crude incidence rate was higher in children and adolescents aged 10 to <15 years (4.56/105) than in other age groups (all P<0.05). The standardized incidence rate was higher in females than in males (3.49/105 vs. 3.04/105, P<0.05). The standardized incidence rate was higher in urban areas than in rural areas (3.60/105 vs. 3.15/105, P<0.05). The crude and standardized incidence rates of type 2 diabetes mellitus were 3.43/105 and 3.87/105, respectively, showing upward trends (AAPC=4.904%, 7.579%, both P<0.05). The crude incidence rate was higher in children and adolescents aged 15 to 18 years (10.53/105) than in other groups (all P<0.05). The crude incidence rates in children and adolescents who aged 10 to <15 years and 15 to 18 years showed upward trends (AAPC=15.030%, 6.637%, both P<0.05). The standardized incidence rate was higher in males than in females (4.01/105 vs. 3.57/105, P<0.05). The standardized incidence rate was higher in urban areas than in rural areas (4.57/105 vs. 3.34/105, P<0.05). Conclusions From 2011 to 2021, the incidence of type 2 diabetes mellitus showed an upward trend, with cases mainly concentrated in children and adolescents aged 15 to 18 years, males, and those living in urban areas. The incidence of type 1 diabetes mellitus remained stable, with cases mainly concentrated in children and adolescents aged 10 to <15 years, females, and those living in urban areas.

Objective:To understand intensive care unit(ICU)doctors'opinions and suggestions on implementing palliative care,and provides a reference basis for the implementation of palliative care in Chinese ICU.Methods:A purposive sampling technique was used to conduct one-on-one semi-structured interviews with 11 ICU doctors.Colaizzi's phenomenological analysis method was utilized to code,classify,interpret,and comprehensively analyze the interview data.Results:A total of 4 themes and 18 sub-themes was extracted,including cognitive biases toward palliative care,the belief that implementing palliative care in the ICU has significant humanistic implications(palliative care practice is the most perfect embodiment of medical humanities,palliative care in the ICU can alleviate patient pain and reduce invasive operations,palliative care can achieve comfortable care for ICU patients,palliative care focuses on maintaining the dignity of ICU patients,palliative care can pay attention to the inner voice of ICU patients,and implementing palliative care will help to more effectively allocate resources),difficulties faced by ICU in carrying out palliative care(lack of clarity in relevant policies at the legal level,closed management environment in the ICU,insufficient manpower in the ICU and lack of palliative care professional team,inadequate understanding of ICU patients'families,lack of death education,not included in medical insurance payments,and lack of communication skills of young doctors),strategies to promote the development of palliative care in the ICU(ICU palliative care can be piloted first,the development of ICU palliative care screening tools will help with the development of palliative care,the palliative environment and the handling of death procedures can be further optimized,and the application and implementation of scientific methods to shorten the gap between evidence and practice of palliative care).Conclusions:The integration of palliative care and ICU in China is still blank.The significance of implementing palliative care in ICU should be emphasized,ICU doctors'knowledge and skills of palliative care should be improved from multiple perspectives,patient preference should be emphasized to improve the knowledge and acceptance of palliative care of ICU patients'families,and the promotion of palliative care in ICU clinical practice should be pioneered and piloted.

Chronic fatigue syndrome(CFS)is a chronic comprehensive disease with a slow course and often accompanied by a variety of physical and psychiatric symptoms.At present,the incidence rate is on the rise.Based on the theory of"qi-pulse smooth and unobstructed",the pathogenesis of CFS is considered to be the loss of spleen and kidney and the deficiency of qi-pulse as the root;liver and lung disorders,qi-pulse stagnation as the pivot;wind fire invasion,phlegm blood stasis as the superficiality.Treatment should focus on tonifying the spleen and tonifying the kidneys to treat its root cause.According to the degree of deficiency of spleen and kidney and the emphasis of deficiency of qi-blood yin-yang,Buzhong Yiqi Decoction,Guipi Decoction,Shengyang Yiwei Decoction,Linggui Zhugan Decoction and Shenqi Pills should be selected flexibly.The methods of soothing the liver and regulating the lungs to regulate their pivot,harmonizing the liver and lungs,and using both ascending and descending functions should be used.Chaihu Shugan Powder,Xiaoyao Powder,Sini Powder,Guizhi Decoction,Shengmai Powder,etc.could be selected flexibly according to the disease location and disease focus.Clearing wind and clearing heat,eliminating phlegm and promoting blood circulation should be used to treat its superficiality,emphasizing tonifying deficiency and resolving depression.According to the different pathogenesis of patients,the corresponding treatment method should be flexibly chosen to supplement with medication.One medical case was attached in this article as the evidence,in order to provide reference for the TCM treatment of CFS.

The immune related adverse events(irAE)caused by tumor immune checkpoint inhibitors(ICI)have attracted increasing attention of clinical experts.Immune-mediated liver injury caused by ICIs(ILICI)is not uncommon in clinical practice,but specific diagnostic method of ILICI is lacking.Biopsy of liver tissue can help improve the diagnosis and management of ILICI.In the treatment of ILICI,the immediate use of corticosteroid therapy is not necessarily.A balance between efficacy,toxicity,and specific treatment need to be achieved,and further refined through multidisciplinary team(MDT)cooperation.Appropriate dosaging and identification of novel predictive targets should be considered in order to reduce the incidence and severity of ILICI in the future.Meanwhile,further basic research is required to elucidate the potential pathophysiological mechanisms and risk factors of ILICI.With the refinement of evidence in clinical evidence-based medicine and deepening of basic research,the diagnosis and treatment level of ILICI will also be further improved.

Mitochondrial dysfunction after spinal cord injury (SCI) is recognized as a crucial pathological mechanism for secondary SCI. Studies have indicated that mitochondrial transfer plays a significant role in the process of neural regeneration following injury. After mitochondria migrating to injured neurons, they mainly function via enhancing the energy metabolism level of damaged neurons and reducing oxidative stress. In this article, we present an exhaustive overview on mechanism of mitochondrial transfer, and impact on neural regeneration after mitochondrial transfer so as to provide valuable insights for further exploring the role of mitochondrial transfer in SCI progression and offer innovative perspective on potential therapeutic strategies for SCI.

Objective To explore the optimal virtual monoenergetic image of superior thyroid artery(STA)based on dual-layer spectral detector CT,and to optimize the image quality of STA.Methods A total of 100 patients who underwent dual-phase neck enhanced spectral CT scan were selected retrospectively.The 120 kVp conventional images and the 40-70 keV(interval of 10 keV)virtual monoenergetic images in the arterial phase were analyzed.The CT values,background noise,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of blood vessels and surrounding tissues were analyzed in the five groups of images,and the image quality was scored.Results In monoenergetic image groups,the CT values,SNR and CNR of STA increased with the monoenergetic level decreased,and the highest values were found when the monoenergetic level was 40 keV,which was significantly higher than those in the 120 kVp conventional image group(P＜0.05).The background noise increased with the monoenergetic level decreased,and reached the maximum at 40 keV,but it was still lower than that in the 120 kVp conventional image group,and the difference was statistically significant(P＜0.001).The subjective score of 40 keV image was significantly better than that of 120 kVp conventional image group(P＜0.001).In the evaluation of the origin of the STA in 100 patients,a total of 200 STA were shown,69％of which originated from the external carotid artery.Conclusion The image quality of the STA on the 40 keV monoenergetic image is significantly higher than that on the conventional image,which has obvious advantages in evaluating the anatomy of the STA.

Objective:To investigate the effect of different blood glucose and BMI levels on the outcome of closed biliary surgery in diabetic patients.Methods:Clinical data of 424 diabetes admitted to Shanxi Provincial People’s Hospital for closed biliary tract surgery from Jan. 2018 to Jun. 2019 were retrospectively analyzed. According to the fasting blood glucose and BMI levels, the subjects were divided into hyperglycemia and non-hyperglycemia groups and obesity and non-obesity subgroups. The differences of clinical data among different groups were compared and analyzed. Multiple regression analysis was used to analyze the factors of postoperative infection, length and cost of hospitalization.Results:①Compared with the non-hyperglycemia group, the hyperglycemia group had higher BMI, serum creatinine, blood urea nitrogen, blood glucose monitoring rate, glycated hemoglobin detection rate, postoperative infection rate, ICU occupancy rate, length and cost of hospitalization, and lower albumin level, all P<0.05.②The age, fasting blood glucose, serum creatinine, low density lipoprotein, length and cost of hospitalization in the hyperglycemic obese subgroup were all lower than those in the non-obese subgroup, all P<0.05; and the serum creatinine in the obese subgroup was higher than those in the non-obese subgroup ( P<0.05) . ③Logistic analysis revealed that hyperglycemia was an independent risk factor for postoperative infection. For every 1mmol/L increase in fasting blood glucose, the risk of postoperative infection increased by 1.158 times, and albumin was a protective factor for postoperative infection. ④Multiple linear regression analysis showed that hyperglycemia and hypoalbumin were the important factors affecting the length of hospital stay and the increase of hospital cost, all P<0.05. Conclusions:Hyperglycemia is an independent risk factor for postoperative infection and a risk factor for longer hospital stay and higher costs. Obesity is not associated with postoperative infection or longer hospital stay, except for increased serum. Patients with diabetes undergoing closed biliary system surgery need to improve the detection rate of glycated hemoglobin and blood glucose monitoring rate, manage blood glucose reasonably, and control body weight appropriately.

Objective:To explore the common pathogenic gene mutation in non-syndromic craniosynostosis in Chinese population.Methods:Patients with non-syndromic craniosynostosis were recruited in Huashan Hospital Affiliated to Fudan University from March 2018 to December 2020. A clinical questionnaire was designed to collect the general information of the patients. The gene panel was designed by entering the keywords craniosynostosis and gene panel in PubMed, extracting all relevant literature from January 1995 to May 2017. The gene library was sequenced on the Illumina HiSeq X platform, and bioinformatic analysis and pathogenic analysis were performed.Results:A total of 237 literatures were reviewed in the PubMed and Ovid databases, and the total sample was 3375 patients, of which 1822 cases (54%) were detected with corresponding mutations, involving 21 pathogenic genes. Based on the mutation detection rate of not less than 0.4%, 12 genes were selected in the gene panel: FGFR2, TWIST1, FGFR3, EFNB1, FGFR1, SKI, POR, RAB23, TCF12, MSX2, SMAD3 and ERF. A total of 109 patients with non-syndromic craniosynostosis were recruited in this study, including 62 males and 47 females; the average age was 2.1 years old. All participants denied family history. The average age at childbearing of father was 28.3 years old and of mother was 26.7 years old. 14 different pathogenic/ probable pathogenic mutation loci were found in the gene sequences of 19 patients. The mutation rate was 17.4%. The 14 mutation varients were distributed in 5 genes (FGFR2, TWIST1 , TCF12, EFNB1 , and FGFR3) . The 14 mutations can be classified into 5 missense mutations, 3 nonsense mutations, 1 splice mutation, 1 frameshift mutation and 4 in-frame deletion mutations, 11 of which have not been reported. These 11 novel mutations were mainly concentrated in two genes, TWIST1 and TCF12. The mutation types included: 3 loss-of-function, 4 frameshift deletions, 3 missense mutations, and 1 frameshift insertion, of which 7 were de novo mutation.Conclusions:TWIST1 and TCF12 are common pathogenic genes in Chinese patients with non-syndromic craniosynostosis.
