OBJECTIVES: In the early stage of central cervical disc herniation, clinical symptoms may be mild. However, as the spinal cord becomes compressed by herniated nucleus pulposus tissue, progressive edema and degeneration may occur, resulting in more severe clinical manifestations, including limb weakness, bladder and bowel dysfunction, spastic paraplegia of the lower extremities, and even respiratory difficulty. The spinal endoscopic Key-hole technique is widely applied in treating radiculopathic cervical spondylosis and has demonstrated good clinical outcomes. This study aims to analyze and summarize the technical points and therapeutic efficacy of the far lateral Key-hole technique in the treatment of central cervical disc herniation, providing reference for clinical application. METHODS: Eight patients with central cervical disc herniation treated with the far lateral Key-hole technique were included as the experimental group. Another 8 patients who underwent single-level anterior cervical diskectomy and fusion (ACDF) during the same period were selected as the control group. Data collected included gender, age, intraoperative blood loss, incision length, and length of hospitalization. Pain severity was evaluated using the Visual Analogue Scale (VAS); cervical function was assessed using the Japanese Orthopaedic Association (JOA) score; and cervical disability was measured by the neck disability index (NDI). Radiological outcomes were assessed using disc height index (DHI), cervical Cobb angle, and operative segment Cobb angle. RESULTS: Compared with the control group, the experimental group had significantly less intraoperative blood loss, shorter incision length, and shorter hospital stay (all P<0.05), while there was no significant difference in operation time (P>0.05). Postoperative VAS and NDI scores in both groups were significantly lower than preoperative values, and JOA scores significantly improved (P<0.05). No significant differences were noted between the two groups preoperatively (P>0.05). Postoperatively, the experimental group showed significantly lower VAS and NDI scores and higher JOA scores than the control group (P<0.05). There was no statistical significance in DHI before and after surgery in the experimental group (P>0.05), while the DHI increased significantly postoperatively in the control group (P<0.05). Postoperative DHI in the experimental group was significantly lower than in the control group (P<0.05). No significant differences were observed in the cervical Cobb angle either within or between groups (all P>0.05). The operative segment Cobb angle increased significantly after surgery in the control group (P<0.05), while no other operative segment angle changes were statistically significant (all P>0.05). CONCLUSIONS The far lateral Key-hole technique offers advantages in treating central cervical disc herniation, including reduced intraoperative bleeding, smaller incision length, shorter hospitalization, and improved postoperative pain relief. Additionally, the technique does not affect cervical physiological curvature or stability in the short term, making it suitable for clinical application.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

ObjectiveTo investigate the trends in diabetes mortality rate and the characteristics of decreased population in Fengxian District, Shanghai from 2012 to 2021. MethodsData from the death registration records of the residents in Fengxian District between 2012 and 2021, sourced from the Shanghai Death Surveillance System, were analyzed. Indicators such as the crude mortality rate due to diabetes, the standardized mortality rate, years of life lost (YLL), and the probability of premature death were estimated. Annual percentage change (APC) was used to analyze the temporal trends of mortality and the probability of premature death due to diabetes. Rate decomposition analysis was used to assess the contributions of demographic and non-demographic factors to diabetes mortality. ResultsFrom 2012 to 2021, there were 1 471 deaths due to diabetes in Fengxian District, with a crude mortality rate of 27.51/100 000 and a standardized mortality rate of 17.58/100 000. The crude mortality rate showed an overall increasing trend (APC=4.58%, Z=3.49, P<0.05). The potential years of life lost (PYLL) due to diabetes over this period amounted to 9 715 person-years, with a PYLL rate of 1.82 ‰, and the average years of life lost (AYLL) was 11.94 years. The probability of premature death was 0.41% (APC=3.36%, t=2.33, P<0.05). Both population aging and non-aging factors contributed to the increase in diabetes mortality, with overall contribution rates of 67.99% and 32.01%, respectively. Among men, the contribution rates were 60.57% and 39.43%, while among women, they were 79.43% and 20.57%, respectively. ConclusionFrom 2012 to 2021, both the crude mortality rate and the probability of premature death due to diabetes showed an upward trend among the residents in Fengxian District, with a higher YLL. Population aging was the main factor causing the increase in mortality rate, while non-demographic factors had a greater impact on the rise in diabetes mortality among men than that in women. Therefore, the management on male diabetes patients should be strengthened.

Objective To assess the clinical and cranial CT/MR features of leptomeningeal metastasis(LM)from lung adenocar-cinoma with non-enhanced T2-fluid attenuated inversion recovery(T2-FLAIR)hyperintensity on the brainstem surface.Methods Eleven cases with LM from lung adenocarcinoma with non-enhanced T2-FLAIR hyperintensity on the brainstem surface confirmed by cere-brospinal fluid cytology were analyzed retrospectively.The clinical features included the pathological classification of the primary tumor,genetic testing results,and treatment methods.The imaging features included lesion location,MRI(T1 and T2)signals,diffusion weighted imaging(DWI)signal,enhancement patterns,CT density characteristics.Results The features of non-enhanced T2-FLAIR hyperintensity on the brainstem surface of 11 cases among 98 patients(11.2％)with LM from lung adenocarcinoma were reviewed.All patients were lung adenocarcinomas with epidermal growth factor receptor(EGFR)gene mutation and were diagnosed with LM after receiving EGFR-tyrosine kinase inhibitors(EGFR-TKIs)targeted therapy.There were 5 cases located in the pons,2 cases in the midbrain and pons,and 4 cases involving the midbrain,pons and medulla oblongata with the symmetrical band-like high signal on non-enhanced T2-FLAIR imaging.On T1WI,1 case showed slightly high signal,10 cases showed equal signal.On DWI,4 cases showed high signal,7 cases showed equal signal,and on enhanced T1WI,1 case showed mild enhancement,and 10 cases showed no enhancement.Additionally,on cranial CT scans,1 case showed calcification on the brainstem.Conclusion Non-enhanced T2-FLAIR hyperintensity on the brainstem surface may be more common among LM patient from lung adenocarcinoma with EGFR gene muta-tions and TKIs treatment,with the most frequent site being the pons.The features may include non-enhanced T2-FLAIR high signal,non-enhancement on enhanced T1 WI,restricted diffusion on DWI,and calcifications on CT imaging.

Objective To construct a predictive model for the risk of non-suicidal self-injury(NSSI)in young and middle-aged patients with major depressive disorder based on the decision tree algorithm.Methods Young and middle-aged patients with major depressive disorder admitted to the Chongqing Mental Health Center from January 2021 to June 2023 were selected as the research subjects and their clinical data were collected.According to whether NSSI occurred or not,the patients were divided into the NSSI group(n=72)and the non-NSSI group(n=82).Univariate and multivariate logistic regression analyses were used to analyze the risk factors of NSSI in young and middle-aged patients with major depressive disorder.A deci-sion tree predictive model was established based on the results of logistic regression analysis and the Chi-square Automatic Interaction Detection(CHAID)algorithm.The predictive value of the model was evaluated using Receiver Operating Characteristic(ROC)curve.Results The incidence of NSSI in 154 young and mid-dle-aged patients with major depressive disorder was 46.8％.The results of single-factor analysis showed that there were no statistically significant differences(P＞0.05)in gender,age,education level,occupation,family composition,only child status,relationship status,fertility status,main place of residence,family economic source,and housing conditions between the two groups.Statistically significant differences(P＜0.05)were observed in living conditions,family economic status,duration of depression,SSRS score,PSS-Fa score,and DS score between the two groups.Multi-factor logistic regression analysis showed that lower family economic lev-el,longer duration of depression,SSRS score＜20 points,PSS-Fa score＜6 points,and DS score ≥47.2 points were independent risk factors for NSSI in young and middle-aged patients with major depressive disorder(P＜0.05).The constructed decision tree model had five layers and ten nodes,with family economic situation,duration of depression,SSRS score,and PSS-Fa score selected as the nodes of the model,among which the PSS-Fa score was the most important predictive factor.ROC curve analysis showed that the AUC of the model was 0.881(95％CI:0.844-0.918).Conclusion There are many influencing factors for the occurrence of NSSI in young and middle-aged patients with major depressive disorder.The decision tree model constructed based on these factors has a high predictive value for the risk of NSSI in young and middle-aged patients with major depressive disorder.

Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.

AIM: To explore the effects of prolonged sevoflurane exposure on prefrontal cortical metabolites in aged mice using a metabolomics approach. METHODS: Ten 18-month-old male C57BL/J6 mice were divided into a sevoflurane group (Sev group) and a control group (Con group) by the random number table method, with five mice in each group. Mice in the sevoflurane group were anesthetized with 3% sevoflurane and 60% oxygen for 6 h. Mice in the control group were given 60% oxygen under the same conditions for 6 h. All mice were executed immediately after the end of anesthesia or oxygenation, and fresh prefrontal cortex was taken for LC-MS/MS analysis. The data obtained were processed and analyzed using OSV2.1 software (AB SCIEX). RESULTS: Compared with the control group, the content of glutathione, arginine, coenzyme A, 1-methyl-histi-dine, L-arginino-succinate and 2-isopropylmalic acid was reduced in the prefrontal cortex of aged mice in the sevoflurane group, while the content of mesaconic acid was increased. A total of 29 metabolic pathways were involved in the differential metabolites, with significant enrichment in nine pathways including arginine biosynthesis. CONCLUSION: Significant changes in metabolites such as glutathione, arginine, and coenzyme A occurred in the prefrontal cortex of aged mice exposed to prolonged sevoflurane. The changes in these products may affect the amino acid metabolic pathway and the gluconeogenic pathway.

Objective:To evaluate the effects of bosutinib on acute lung injury in mice with endotoxemia.Methods:Sixty clean-grade healthy male C57BL/6 mice, aged 8-12 weeks, weighing 20-25 g, were divided into 4 groups ( n=15 each) using a random number table method: control group (group C), bosutinib group (group B), endotoxemia group (group lipopolysaccharide [LPS]) and bosutinib plus endotoxemia group (group B+ LPS). Septic acute lung injury model was developed by intraperitoneal injection of LPS.Bosutinib 5 mg/kg was injected via the tail vein at 0.5 h before establishing the model in group B+ LPS and at the corresponding time point in group B. At 24 h after developing the model, the mice were sacrificed for microscopic examination of the pathological results of lung tissues which were scored for calculation of the lung coefficient (LI) and wet/dry lung weight (W/D) ratio, and for determination of the content of Evans blue in lung tissues (by Evans blue staining), expression of vascular endothelial cadherin (VE-cadherin), vascular cell adhesion molecule 1 (VCAM-1), phosphorylated nuclear transcription factor κB p65 (p-NF-κB p65), phosphorylated nuclear factor κB inhibitory protein α (pIκB-α) (by Western blot) and expression of interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) mRNA (using real-time polymerase chain reaction). Results:Compared with group C, the LI, W/D ratio, Evans blue content in lung tissues and lung injury score were significantly increased, and the expression of IL-1β mRNA, TNF-α mRNA, IL-6 mRNA, VCAM-1, p-NF-κB p65 and pIKB-α was up-regulated, and the expression of VE-cadherin was down-regulated in group LPS ( P<0.05), and no significant change was found in the parameters mentioned above in group B ( P>0.05). Compared with group B, the LI, W/D ratio, Evans blue content in lung tissues and lung injury score were significantly decreased, and the expression of IL-1β mRNA, TNF-α mRNA, IL-6 mRNA, VCAM-1, p-NF-κB p65 and pIKB-α was down-regulated, and the expression of VE-cadherin was up-regulated in group LPS ( P<0.05). Conclusions:Bosutinib can ameliorate the acute lung injury in mice with endotoxemia.
