Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To investigate the therapeutic effect of cnithol on acute pancreatitis(AP)rats and its regulatory mechanism on phosphoinositol 3-kinase(PI3K)/protein kinase B(Akt)signaling pathway.Methods SPF-grade SD male rats were randomly divided into control group,model group(50 μg·kg-1 hyranin+10 mg·kg-1 LPS),positive control group(2 mg·kg-1 dexamethasone),experimental-L group(20 mg·kg-1 osthol)and experimental-H group(40 mg·kg-1 osthol),experimental-H+740Y-P group(40 mg·kg-1 osthol+2 mg·kg-1 PI3K activator 740Y-P),15 mice in each group.The activities of amylase and lipase in serum of rats were detected by automatic biochemical analyzer 24 h after the last administration.The levels of inflammatory factors tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)in serum,the content of malondialdehyde(MDA)and the activity of superoxide dismutase(SOD)in pancreas were detected by enzyme-linked immunosorbent assay(ELISA).Hematoxylin-eosin(HE)staining was used to observe the pathological changes of pancreatic tissue and score the pathological damage.Western blot was used to detect the expression of PI3K/Akt pathway related proteins in rat pancreas.Results The activities of serum amylase in control group,model group,positive control group,experimental-H group and experimental-H+740Y-P group were(135.67±12.89),(1 027.84±32.16),(174.31±15.27),(186.70±17.39)and(835.92±28.78)U·mL-1,respectively;the contents of TNF-α were(35.69±3.10),(223.54±15.23),(48.76±4.25),(52.31±4.68)and(208.46±13.65)pg·mL-1,respectively;the contents of MDA were(2.15±0.14),(6.37±0.42),(2.78±0.17),(2.81±0.15)and(5.96±0.36)nmol·mg-1,respectively;the histopathological injury scores were 1.12±0.07,10.23±0.38,3.14±0.21,3.25±0.23 and 9.68±0.40,respectively;p-PI3K/PI3K ratios were 0.82±0.05,1.96±0.15,1.07±0.06,1.10±0.07 and 1.69±0.14,respectively.The above indexes were compared with the control group in the model group,the positive control group,experimental-H group and the model group,and the above indexes of experimental-H+740Y-P group and experimental-H group,and the differences were statistically significant(all P＜0.05).Conclusion Gossetin can play a therapeutic role in AP,and its mechanism may be related to the inhibition of PI3K/Akt signaling pathway.

Objective To explore the effect of Shexiang Baoxin pill on cardiac tissue angiogenesis in spontaneously hypertensive rats(SHR).Method Twenty 12 week old male SHR were randomly divided into experimental group and model group,with 12 week old male SD rats as the normal control group.The experimental group rats were orally administered with Shexiang Baoxin pill(45 mg·kg-1)daily,and their blood pressure was monitored using a non-invasive tail artery blood pressure gauge every four weeks.Eight weeks later,cardiac tissue was taken for platelet endothelial cell adhesion molecule-1(PECAM-1/CD31)immunofluorescence staining to observe CD31 expression level.Use protein blotting to detect the expression levels of myocardial endothelial growth factor(VEGF),myocardial endothelial growth factor receptor 2(VEGF-R2),basic fibroblast growth factor(bFGF)and phosphorylated protein kinase B(p-Akt)/protein kinase B(Akt)proteins.Result There was significant increase in blood pressure between the experimental group,model group and normal group at the same time point(all P＜0.01),but there was no statistically significant difference in blood pressure changes between the experimental group and model group at the same time point(all P＞0.05).The CD31 expression rates of the normal group,model group and experimental group were(3.79±0.84)％,(2.54±0.42)％and(3.56±0.49)％;VEGF levels were 0.95±0.10,0.73±0.08 and 0.94±0.15;VEGF-R2 levels were 0.85±0.10,0.61±0.14 and 0.80±0.10;bFGF levels were 0.84±0.04,0.51±0.21 and 0.74±0.14;p-Akt/Akt levels were 0.85±0.15,0.57±0.13 and 0.80±0.20,respectively.The differences between the normal group and the model group,as well as the experimental group and the model group,were statistically significant(all P＜0.05).Conclusion Shexiang Baoxin pill can promote the neovascularization of microvessels in the heart tissue of spontaneously hypertensive rats,and its mechanism may be related to the activation of PI3K/Akt phosphorylation,upregulation of bFGF,VEGF and their receptor VEGF-R2 in myocardial tissue.

Objective To compare the blood glucose control effect and safety between insulin degludec and insulin aspart and insulin aspart 30 in non-obese patients with type 2 diabetes mellitus(T2DM).Methods Non-obese patients with T2DM were divided into treatment group and control group according to different treatment methods.The control group was treated with insulin aspart 30,and the treatment group was treated with insulin degludec and insulin aspart.Pancreatic islet related indicators[fasting C-peptide(FCP)and 2-hour postprandial C-peptide(2 h CP)],blood glucose control effect[fasting blood glucose(FBG),2-hour postprandial blood glucose(2 h PG)and glycated hemoglobin(HbA1c)],serum 25-hydroxyvitamin D[25(OH)D]and the risk of hypoglycemia were compared between the two groups.Results There were 41 cases in treatment group and 39 cases in control group.After treatment,FCP levels in treatment group and control group were(0.84±0.09)and(1.07±0.14)nmol·L-1;2 h CP levels were(1.03±0.15)and(1.69±0.17)nmol·L-1;FBG levels were(5.46±0.57)and(6.18±0.67)mmol·L-1;2 h PG levels were(8.17±0.85)and(9.03±0.94)mmol·L-1;HbA1 c were(5.35±0.57)％and(6.47±0.68)％;25(OH)D levels were(26.33±2.75)and(20.54±2.17)nmol·L-1,all with significant difference(all P＜0.05).The incidence rates of non-severe hypoglycemia in treatment group and control group were 14.63％and 35.90％,with statistically significant difference(P＜0.05).The incidence rates of severe hypoglycemia in treatment group and control group were 9.76％and 12.82％;the incidence rates of nocturnal hypoglycemia were 19.51％and 17.95％,without statistically significant difference(all P＞0.05).Conclusion The overall therapeutic effect of insulin degludec and insulin aspart on non-obese patients with T2DM is better than that of insulin aspart 30.The former can effectively regulate blood glucose and pancreatic islet cell function,lower the risk of non-severe hypoglycemia.

Objective To explore potential predictive biomarkers for preeclampsia by analyzing the expression and characteristics of vascular-related inflammatory proteins in the serum of preeclamptic pregnant women.Methods A case-control study was conducted from Sep 2017 to Sep 2018 in the Obstetrics and Gynecology Hospital,Fudan University.Preeclamptic pregnant women and normotensive pregnant controls during the same period were recruited.The concentration of 12 vascular inflammation-related proteins in the patients'serum was determined by multiplex flow cytometry.The vascular-related inflammatory molecules were subjected to differential analysis by non-parametric t-test to obtain preeclampsia-related vascular inflammatory proteins.Finally,high-risk preeclampsia pregnancy serum samples from the biobank were retrieved.Serum concentrations of preeclampsia-related vascular inflammatory proteins were determined,and receiver operating characteristic(ROC)curve analysis was conducted for preliminary predictive assessment of preeclampsia.Results This study conducted a quantitative analysis of serum vascular inflammatory proteins in 39 cases of preeclampsia and 43 cases of control pregnant women,detecting 10 vascular inflammatory proteins expressed in maternal serum.Among these,myoglobin and vascular cell adhesion molecule-1(VCAM-1)exhibited significant elevation in the serum of preeclamptic pregnant women,while matrix metalloproteinase-9(MMP-9)showed a marked decrease.ROC curve analysis revealed that in 96 high-risk early pregnancy women,the area under the curve(AUC)for VCAM-1 reached 0.802,whereas myoglobin and MMP-9 did not significantly predict the occurrence of preeclampsia.Conclusion Preeclampsia patients exhibit abnormal expression of serum inflammatory proteins,among which VCAM-1 may be a potential biological marker for early pregnancy preeclampsia risk prediction.

Objective To summarize the treatment of cervical cancer patients diagnosed before 34 weeks of gestation who chose to continue pregnancy,and to provide clinical experience for improving maternal and fetal outcomes.Methods Clinical data of pregnant women with cervical cancer admitted to the Obstetrics and Gynecology Hospital,Fudan University from Jan 2013 to Feb 2024 were collected and analyzed.Treatment of patients diagnosed before 34 weeks of gestation and chose to continue pregnancy was summarized.Outcomes of patients and newborn were followed up.Results A total of 15 patients were enrolled with a median age of 34 years old.Nine cases(9/15)represented clinical symptom of abnormal vaginal bleeding,14 cases(14/15)of patients were diagnosed in the middle or late stages of pregnancy,12 cases(12/15)diagnosed with tumor size of more than 2 cm,13 patients(13/15)infected HPV type 16 or 18.The main pathological type was squamous cell carcinoma(9/15).Regarding therapy,one patient with stage Ⅰa1 was under observation and underwent a caesarean section and total hysterectomy at 35 weeks of gestation due to premature rupture of membrane and a scarred uterus.For the other patients with 14 stage Ⅰb,lymph node metastasis was excluded by pelvic lymphadenectomy or MRI,and then neoadjuvant chemotherapy was administered.Termination of pregnancy and standardized treatment for cervical cancer were provided after 34 weeks of gestation.One patient's pathology was upgraded to stage Ⅱa1 after surgery.Up to follow-up,13 out of 15 patients had survived without tumors.The average gestational age of newborns was(35.0±1.5)weeks,and the average birth weight was(2 345.33±431.44)g.Blood tests conducted one day after delivery of the newborns revealed that:8 newborns(8/15)had hypoleukocyte and one newborn(1/15)had anemia.After short-term hospitalization and supportive treatment,all newborns'progress was favorable.Conclusion For pregnant patients with stage Ⅰb cervical cancer diagnosed before 34 weeks of gestation,postponing termination to after 34 weeks of gestation through neoadjuvant chemotherapy and then giving standardized treatment for cervical cancer was safe with favorable maternal and fetal prognosis.

Objective To investigate the distribution of the traditional Chinese medicine(TCM)constitution types in the patients with nonspecific low back pain(NLBP)and to explore the correlation of the thickness of ligamentum flavum with the age,body mass index(BMI),gender,the presence of diabetes mellitus,and the grading of hypertension.Methods Sixty patients with NLBP admitted to Guangdong Second Traditional Chinese Medicine Hospital from January 2023 to June 2023 were selected as the study subjects.The TCM constitution types of the patients were identified,the thickness of the ligamentum flavum at lumbar vertebrae 4/5 segment(L4/5)disc level was measured by computerized tomography(CT)scanning,and the patients'age,genders,TCM constitution types,BMI,the presence or absence of diabetes mellitus,and hypertension grading were recorded.Correlation analysis and linear regression analysis were used for the exploration of the relevant influencing factors for the thickness of the ligamentum flavum of patients with NLBP.Results(1)The average thickness of ligamentum flavum in the 60 patients with NLBP was(2.60±0.72)mm.(2)The TCM constitutions of NLBP patients were classified into four types,of which blood stasis constitution was the most common,accounting for 21 cases(35.0%),followed by 19 cases(31.7%)of damp-heat constitution,12 cases(20.0%)of phlegm-damp constitution,and 8 cases(13.3%)of qi deficiency constitution.(3)The results of correlation analysis showed that BMI,gender,TCM constitution type and the presence or absence of diabetes mellitus had no influence on the thickness of ligamentum flavum in NLBP patients(P＞0.05),while the age and hypertension grading had an influence on the thickness of ligamentum flavum(P＜0.01).(4)The results of linear regression analysis showed that the age had an influence on the thickness of the ligamentum flavum(b = 0.034,t = 6.282,P＜0.01),while the influence of the hypertension grading had no influence on the thickness of the ligamentum flavum(P＞0.05).Conclusion The TCM constitution type of NLBP patients is predominated by blood stasis constitution,the thickness of ligamentum flavum is significantly affected by the age,and hypertension may be a potential factor affecting the thickness of ligamentum flavum.

Objective To observe the clinical efficacy of"triple-posture positive bone-setting"chiropractic manipulation combined with Tongluo Huoxue Formula for the treatment of lumbar spinal stenosis(LSS)with qi deficiency and blood stasis syndrome.Methods Sixty patients with LSS of qi deficiency and blood stasis type were randomly divided into trial group and control group,with 30 cases in each group.The trial group was treated with"triple-posture positive bone-setting"chiropractic manipulation(a chiropractic manipulation performed under the positive cooperation of the patients at three postures)combined with Tongluo Huoxue Formula,while the control group was treated with"triple-posture positive bone-setting"chiropractic manipulation combined with conventional western medicine.The course of treatment for the two groups covered 4 weeks.Before and after treatment,the patients of the two groups were observed in the changes of pain visual analogue scale(VAS)score,Japanese Orthopedic Association(JOA)score of lumbar function,Oswestry Disability Index(ODI)score,straight-leg raising test results and serum interleukin 6(IL-6)and C-reactive protein(CRP)levels.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 4 weeks of treatment,the total effective rate of the trial group was 96.67％(29/30)and that of the control group was 63.33％(19/30).The intergroup comparison(tested by Fisher's exact test)showed that the clinical efficacy of the trial group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the lumbar function indicators of pain VAS scores and ODI scores in the trial group were significantly lower(P＜0.05),and the JOA scores were significantly higher than those before treatment(P＜0.05),while in the control group,only the ODI scores were significantly lower than those before treatment(P＜0.05).The intergroup comparison showed that the decrease of VAS and ODI scores and the increase of JOA scores in the trial group were significantly superior to those in the control group(P＜0.05 or P＜0.01).(3)After treatment,the Laseque s sign of the trial group was significantly improved compared with that before treatment(P＜0.05),while no significant improvement was presented in the control group(P＞0.05).The intergroup comparison showed that the improvement of Laseque's sign in the trial group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the levels of serum inflammatory factors of IL-6 and CRP in the two groups were lower than those before treatment(P＜0.05),and the decrease of serum IL-6 level in the trial group was significantly superior to that in the control group(P＜0.05),but CRP level in the two groups after treatment did not differ from that before treatment,no statistically significant difference was shown between the two groups after treatment,either(P＞0.05).(5)The incidence of adverse reactions in the trial group was 6.67％(2/30)and that in the control group was 13.33％(4/30),and the intergroup comparison(by Fisher's exact test)showed that there was no significant difference between the two groups(P＞0.05).Conclusion The therapeutic effect of"triple-posture positive bone-setting"chiropractic manipulation combined with Tongluo Huoxue Formula exert certain effect for the treatment of LSS patients with qi deficiency and blood stasis syndrome,and it has more obvious advantages in improving the lumbar function,promoting the rehabilitation of the patients,and lowering the level of serum inflammatory factors than"triple-posture positive bone-setting"chiropractic manipulation combined with conventional western medication.
