Objective To investigate the efficacy of Castor branching stent in treating Stanford type B aortic dissection(TBAD)involving aortic arch.Methods The clinical data of 18 patients with Stanford TBAD,who were treated with Castor branching stent at the Suining Municipal Central Hospital of China from January 2020 to January 2022,were retrospectively analyzed.Results The main bracket and branch bracket of Castor branching stent were successfully released in all the 18 patients with a surgical success rate of 100％,and no internal leakage occurred during operation.During the perioperative period,there were neither aorta-related deaths nor serious complications such as stroke,upper limb ischemia,internal leakage,or stent displacement.The patients were followed up for(14.7±8.3)months,no aorta-related death,stroke,upper limb ischemia,internal leakage,or stent displacement was observed,the blood flow of the left subclavian artery(LSA)was unobstructed,but there was thrombosis formation within the false lumen of the covered stent segment.Conclusion The Castor branching stent has the advantages of reasonable release mode,accurate positioning,effective isolation of the first rupture of Stanford TBAD and reconstruction of LSA,with no serious short-term complications.However,further follow-up observation is needed before its long-term efficacy can be clarified.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Colorectal cancer(CRC) is a common malignant tumor worldwide. Due to the treatment intolerance and side effects, CRC rank the top among various cancers regarding the incidence and mortality rates. Therefore, exploring new therapies is of great significance for the treatment of CRC. Aerobic glycolysis(AEG) plays an important role in the microenvironment formation, proliferation, metastasis, and recurrence of CRC and other tumor cells. It has been confirmed that intervening in the AEG pathway can effectively curb CRC. The active ingredients and compound prescriptions of traditional Chinese medicine(TCM) can effectively inhibit the proliferation, metastasis, and drug resistance and regulate the apoptosis of tumor cells by modulating AEG-associated transport proteins [eg, glucose transporters(GLUT)], key enzymes [hexokinase(HK) and phosphofructokinase(PFK)], key genes [hypoxia-inducible factor 1(HIF-1) and oncogene(c-Myc)], and signaling pathways(MET/PI3K/Akt/mTOR). Accordingly, they can treat CRC, reduce the recurrence, and improve the prognosis of CRC. Although AEG plays a key role in the development and progression of CRC, the specific mechanisms are not yet fully understood. Therefore, this article delves into the intrinsic connection of the targets and mechanisms of the AEG pathway with CRC from the perspective of tumor cell glycolysis and explores how active ingredients(oxymatrine, kaempferol, and dioscin) and compound prescriptions(Quxie Capsules, Jiedu Sangen Decoction, and Xianlian Jiedu Prescription) of TCM treat CRC by intervening in the AEG pathway. Additionally, this article explores the shortcomings in the current research, aiming to provide reliable targets and a theoretical basis for treating CRC with TCM.

To improve the quality evaluation system of Hibisci Mutabilis Folium, this study established high performance liquid chromatography(HPLC) fingerprints of Hibisci Mutabilis Folium and evaluated the quality differences of medicinal materials from different places of production by chemometrics. Furthermore, a content measurement method of differential components was established based on quantitative analysis of multi-components by single-marker(QAMS). The fingerprints of 17 batches of Hibisci Mutabilis Folium from different places of production were constructed, with a total of 19 common peaks marked and seven components confirmed. The similarity between the sample fingerprints and the reference fingerprints ranged from 0.890 to 0.974. By utilizing principal component analysis(PCA), hierarchical cluster analysis(HCA), and orthogonal partial least squares-discriminant analysis(OPLS-DA), the chemical patterns of fingerprints were identified. Five components that could be used to evaluate the quality differences of Hibisci Mutabilis Folium were screened, namely peak 6(quercetin 3-O-β-robinobioside), peak 7(rutin), peak 9(kaempferol-3-O-β-robinobioside), peak 10(kaempferol-3-O-rutinoside), and peak 14(tiliroside). The relative correction factors of isoquercitrin, kaempferol-3-O-β-robinobioside, kaempferol-3-O-rutinoside, kaempferol-3-O-β-D-glucoside, and tiliroside were measured with rutin as the internal reference. The QAMS method was established for the content measurement of six flavonoids, and the results showed there was no significant difference compared to the results obtained by an external standard method. In summary, the HPLC fingerprints and QAMS method established in the study, demonstrating stability and accuracy, can provide a reference for the overall quality evaluation of Hibisci Mutabilis Folium.

PURPOSE: To investigate the incidence and influencing factors of bone loss in patients with spinal cord injury (SCI). METHODS: A retrospective case-control study was conducted. Patients with SCI in our hospital from January 2019 to March 2023 were collected. According to the correlation between bone mineral density (BMD) at different sites, the patients were divided into the lumbar spine group and the hip joint group. According to the BMD value, the patients were divided into the normal bone mass group (t > -1.0 standard deviation) and the osteopenia group (t ≤ -1.0 standard deviation). The influencing factors accumulated as follows: gender, age, height, weight, cause of injury, injury segment, injury degree, time after injury, start time of rehabilitation, motor score, sensory score, spasticity, serum value of alkaline phosphatase, calcium, and phosphorus. The trend chart was drawn and the influencing factors were analyzed. SPSS 26.0 was used for statistical analysis. Correlation analysis was used to test the correlation between the BMD values of the lumbar spine and bilateral hips. Binary logistic regression analysis was used to explore the influencing factors of osteoporosis after SCI. p < 0.05 was considered statistically significant. RESULTS: The incidence of bone loss in patients with SCI was 66.3%. There was a low concordance between bone loss in the lumbar spine and the hip, and the hip was particularly susceptible to bone loss after SCI, with an upward trend in incidence (36% - 82%). In this study, patients with SCI were divided into the lumbar spine group (n = 100) and the hip group (n = 185) according to the BMD values of different sites. Then, the lumbar spine group was divided into the normal bone mass group (n = 53) and the osteopenia group (n = 47); the hip joint group was divided into the normal bone mass group (n = 83) and the osteopenia group (n = 102). Of these, lumbar bone loss after SCI is correlated with gender and weight (p = 0.032 and < 0.001, respectively), and hip bone loss is correlated with gender, height, weight, and time since injury (p < 0.001, p = 0.015, 0.009, and 0.012, respectively). CONCLUSIONS The incidence of bone loss after SCI was high, especially in the hip. The incidence and influencing factors of bone loss in the lumbar spine and hip were different. Patients with SCI who are male, low height, lightweight, and long time after injury were more likely to have bone loss.

BACKGROUND:With the rapid development of minimally invasive spinal surgery and enhanced recovery after surgery,endoscopic intervertebral fusion techniques have gradually emerged and been widely used in clinical practice in recent years. OBJECTIVE:To analyze the early clinical efficacy of uniaxial spinal endoscopic intervertebral fusion combined with posterior percutaneous pedicle screw fixation in the treatment of lumbar degenerative diseases. METHODS:135 patients with lumbar degenerative diseases treated by uniaxial spinal endoscopic intervertebral fusion combined with posterior percutaneous pedicle screw fixation in the Suining Central Hospital from October 2020 to December 2021 were enrolled in this study.There were 59 males and 76 females,aged 47-79 years.The lower limb and lumbar pain was evaluated by visual analog scale and lumbar function was assessed by Oswestry disability index before the operation,1 week,1,and 6 months after the operation,and at the end of follow-up.The overall pain recovery of patients was evaluated by the scoring criteria for low back pain surgery of Spine Group of Chinese Orthopedic Association and the lumbar physiological curvature and intervertebral fusion were evaluated on lumbar lateral X-ray preoperatively and at the end of follow-up. RESULTS AND CONCLUSION:(1)The 135 patients were followed up for(17.8±3.0)months after surgery.There was 1 case of endplate injury,1 case of cerebrospinal fluid leakage,1 case of nerve root injury,1 case of intervertebral cage subsidence and displacement,1 case of chronic infection,and 1 case of pedicle screw rupture.The complication rate was 5.2%.(2)The lumbar visual analog scale score and Oswestry disability index significantly decreased in the waist and lower limbs at various time points postoperatively compared with those preoperatively in 135 patients(P<0.05).The scoring criteria for low back pain surgery of the Spine Group of the Chinese Orthopedic Association were significantly better at the last follow-up than that preoperatively in 135 patients(P<0.05).(3)At the last follow-up,there was no significant difference in physiological curvature of lumbar vertebra as compared with that preoperatively in 135 patients(P>0.05),with a fusion rate of 95.8%.(4)It is concluded that uniaxial spinal endoscopic intervertebral fusion combined with posterior percutaneous pedicle screw fixation in the treatment of lumbar degenerative diseases has shown satisfactory early clinical results and is a highly safe minimally invasive spinal surgery mode.

Objective To investigate the effect of early postoperative abnormal blood glucose on the short-term prognosis of non-small cell lung cancer(NSCLC),and to analyze the clinical characteristics and risk factors related to poor early prognosis.Methods A total of 897 patients with NSCLC who underwent thoracoscopic surgery in Huadong Hospital,Fudan University from Jan 2020 to Aug 2021 were divided into hyperglycemia(HG)group(>7.8 mmol/L)and normal blood glucose(NG)group(≤7.8 mmol/L and≥3.9 mmol/L)according to the early postoperative blood glucose values.Additionally,the patients were divided into higher blood glucose fluctuation group(≥4 mmol/L)and the group with lower blood glucose fluctuation(<4 mmol/L)basing on the fasting blood glucose.Using Logistic regression models,column line charts,ROC curves and other methods,we aimed to clarify the impact of early postoperative blood glucose abnormalities on short-term prognosis,explore clinical characteristics associated with poor short-term outcomes,identify other high-risk factors,and establish relevant risk prediction models.Results Compared with the NG group,the incidence of postoperative pneumonia,thromboembolism,ICU admission rate,total length of hospital stay and hospital cost were significantly higher in the HG group(P<0.05).Higher blood glucose fluctuation group had a greater risk of ICU admission(P=0.003).Logistic regression analysis showed that age,preoperative fasting glucose,white blood cell count and cytokeratin 19 fragment antigen 21-1(CYFRA21-1)were risk factors for postoperative hyperglycemia(P<0.05).Contrary to the effect of BMI,diabetes,male patients,higher blood glucose fluctuation,white blood cell count and age were the risk factors for postoperative adverse events(P<0.05).The AUC of the column line chart model was 0.661(95%CI:0.624-0.698),indicating good discriminative ability for predicting poor short-term prognosis postoperatively.Calibration curves also demonstrated good consistency between predicted and actual probabilities.Conclusion Early postoperative blood glucose fluctuations independently impact the short-term prognosis of thoracoscopic NSCLC patients.Blood glucose combined with gender,BMI,white blood cell count,age and diabetes history can serve as predictive factors for poor short-term prognosis postoperatively.Additionally,a column line chart constructed based on these factors may aid clinicians in early intervention for NSCLC patients with indications.

Objective To investigate the factors influencing the positioning error of conical beam CT(CBCT)radiotherapy and the occurrence of acute radiation dermatitis in breast cancer fixed by cervical and thoracic integrated membrane in order to provide a basis for personalized out-target external boundary,selec-tion of fixed mode and guidance of radiodermatitis clinical practice work.Methods A total of 147 patients with breast cancer in this hospital from June 2022 to October 2023 were selected as the study subjects,inclu-ding 74 cases of breast conserving operation and 73 cases of modified radical(excision)operation.During the treatment period,CBCT scanning once a week obtained the image and conducted the grey match with the planned CT images to acquire the translational error of X(left and right),Y(head and foot)and Z(abdominal and dorsal)and the rotational posing error of X(pitch),Y(roll)and Z(yaw)axis,and at the same time,the acute radiodermatitis in nearly 3 months during radiotherapeutic period was recorded.Results Compared with the Z axis,the translation error of X axis and Y axis was greater,the rotation error was smaller,and the differ-ences were statistically significant(P＜0.05).The PTV external boundary of X,Y and Z axis calculated by the formula was 0.70,0.76,0.46 cm respectively.There was no statistically significant difference in the posi-tioning error of each direction of left and right breast between breast conservation operation and breast resec-tion operation(P＞0.05).The correlation between the age with X,Y and Z axis translation errors was-0.14,0.18 and 0.10 respectively,which of the age with X,Y and Z axis rotation errors was 0.12,＜0.01,0.02 respectively.The occurrence of grade 1 acute radiodermatitis in the patients with breast conserving oper-ation was 100.0％(74/74),which in the patients with excision operation was 13.7％(10/73),the occurrence of grade 2 was 82.2％,which of grade 3 was 4.1％(3/73),and the difference between them was statistically significant(P＜0.05).Conclusion In the every day positioning and target area external expansion,particular attention should be paid to the X and Y axis translational directions and the Z axis rotation direction.Using the integrated cervicothoracic thermoplastic membrane for fixing breast cancer is not affected by the operation mode,affected side position and age.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective:To investigate the effect of microgravity-mediated Notch1 signaling on macrophage polarization on bone homeostasis.Methods:The animal model was constructed by tail-limb suspension(HLS)to simulate the microgravity environment.The animals were grouped into Control group,HLS group,HLS+NC group,HLS+si group,HLS+rhNF-κB group.ELISA was used to detect the content of TNF-α and IL-1β in serum of rats.TUNEL staining was used to detect the apoptosis of bone tissue.Immunofluo-rescence was used to detect the polarization of macrophages in bone tissue.The rat osteoblast CP-R091 microgravity model was con-structed by simulating the microgravity environment with a rotating wall bioreactor.The cell experiments were divided into Control group,HLS group,HLS+NC group,HLS+si group,HLS+rhNF-κB group.CCK-8 test was used to detect the proliferation activity of cells in each group,and AO test was used to test the apoptosis rate of cells in each group.PCR was used to detect the expression of os-teogenesis-related genes in bone tissues and cells.Western blot was used to detect the expression of Notch1,hair division-related en-hancer-1(HES-1),and Notch pathway ligand 1(Jagged1)in bone tissues and cells of each group.Results:Compared with control group,the contents of TNF-α and IL-1β in the serum of the rats in the HLS group,the apoptosis rate,and the proportion of M1 macro-phages were significantly increased.Compared with HLS group,the HLS+si group could obviously partially reverse the change trend of the above parameters,while HLS+rhNF-κB group significantly changed the above parameter values.Compared with control group,the proliferation activity of the cells in the HLS group was significantly reduced,and the apoptosis rate was significantly increased.Com-pared with HLS group,the HLS+si group could obviously partially reverse the change trend of the above parameters,while the HLS+rhNF-κB group made the above parameter values worse.The expressions of the osteogenesis-related genes collagen type Ⅰ(COL1),osteocalcin(OCN)and Runt-related transcription factor 2(RUNX2)in bone tissues and cells in the microgravity environment were significantly decreased,while the expressions of Notch-1,Hes-1 and Jagged1 were significantly increased,and the differences were statistically significant(all P<0.05).Conclusion:Microgravity-mediated Notch1 signaling regulates M1/M2 polarization of macro-phages,participates in cell proliferation and apoptosis in bone tissue,and affects the progress of bone homeostasis.
