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.

Objective To compare the effects of three kinds of artificial hydronephrosis in percutaneous nephrolithotomy.Methods A total of 120 patients who underwent single-tract percutaneous nephrolithotomy in the Eighth Hospital of Wuhan from May 2020 to April 2022 were selected and divided equally into three groups according to different methods of artificial hydronephrosis.Patients in group A were received preoperative indwelling ureteral catheter and injection of normal saline through ureteral catheter to dilate renal pelvis and form artificial hydronephrosis.Patients in Group B were placed with double J catheters before surgery,and the bladder was filled with physiological saline through the catheter.The renal pelvis was dilated through the double J catheters,resulting in artificial hydronephrosis.Patients in Group C were received intravenous injection of furosemide and stimulated diuretic method to actively dilate renal pelvis to form hydronephrosis.The one-time puncture success rate,channel establishment time,overall operation time,stone clearance rate and incidence of surgical complications of percutaneous nephrolithotomy after hydronephrosis were compared among the three groups.Results The operation was successfully completed in the three groups.There was no significant difference in the one-time puncture success rate and channel establishment time between group A and group B(P>0.05),which were all higher than group C(P<0.05).The overall operation time of group B was shorter than that of group A and group C(P<0.05).There were no significant differences in stone clearance rate and surgical complications among the three groups(P>0.05).Conclusion Preoperative indwelling of double J tubes to create artificial kidney hydronephrosis has advantages such as high success rate of one-time puncture,short channel establishment time,and surgical time.

The patient,a male newborn,was admitted to the hospital 2 hours after birth due to prematurity(gestational age 27+5 weeks)and respiratory distress occurring 2 hours postnatally.After admission,the infant developed fever and elevated C-reactive protein levels.On the fourth day after birth,metagenomic next-generation sequencing of cerebrospinal fluid indicated a positive result for Mycoplasma hominis(9 898 reads).On the eighth day,a retest of cerebrospinal fluid metagenomics confirmed Mycoplasma hominis(56 806 reads).The diagnosis of purulent meningitis caused by Mycoplasma hominis was established,and the antibiotic treatment was switched to moxifloxacin[5 mg/(kg·day)]administered intravenously for a total of 4 weeks.After treatment,the patient's cerebrospinal fluid tests returned to normal,and he was discharged as cured on the 76th day after birth.This article focuses on the diagnosis and treatment of neonatal Mycoplasma hominis purulent meningitis,introducing the multidisciplinary diagnosis and treatment of the condition in extremely preterm infants.[Chinese Journal of Contemporary Pediatrics,2024,26(4):432-436]

Aesculus chinensis is an important medicinal and horticultural plant. Its dried mature seeds, known as "Suoluozi", are a well-known traditional Chinese medicine. Aescins are its main active components, possessing multiple pharmacological activities such as anti-inflammatory and anti-exudative effects. They are widely used in the treatment of diseases such as lumbar disc herniation, postoperative edema, and sports injuries, leading to a continuous increase in market demand in recent years. The DNA binding with one finger(Dof) family is a unique transcription factor family found in the plant kingdom. It plays a crucial role in plant growth, development, stress responses, and regulation of secondary metabolism. However, research on the Dof gene family in A. chinensis is relatively scarce. In this study, we identified 36 AcDof genes from the genome of A. chinensis and analyzed their physicochemical properties, chromosomal localization, phylogenetic relationships, gene structures, cis-acting elements, and expression patterns in different tissues. The results showed that AcDof proteins ranged from 81 to 493 amino acids in length, with molecular weights ranging from 9 270.38 to 55 015.68 and isoelectric points ranging from 4.84 to 10.2. The subcellular localization analysis revealed that 34 AcDof proteins were located in the nucleus, while the remaining two AcDof proteins were located in the chloroplasts. Phylogenetic analysis divided AcDofs into nine subgroups, and gene structure analysis indicated that all AcDof genes possessed a C2-C2 type single zinc finger domain. Gene expression analysis using transcriptome data revealed tissue-specific expression patterns among AcDof family members. Specifically, AcDof04, AcDof02, and AcDof03 exhibited specific expression in seeds, suggesting their potential involvement in the regulation of aescin biosynthesis. This study not only enhances our understanding of the Dof gene family in A. chinensis but also provides important genetic resources for further investigation of the functions and regulatory mechanisms of Dof genes in this species.

In recent years, the clinical treatment of colorectal cancer(CRC) has made great progress, but chemoresistance is still one of the main reasons for reducing the survival rate of patients with colorectal cancer. Therefore, ameliorating chemotherapy resis-tance is an urgent problem to be solved. The purpose of this study was to investigate the regulatory role and related molecular mechanisms of hydroxysafflor yellow A(HSYA) in colorectal cancer cell proliferation, migration, and 5-fluorouracil(5-FU) chemoresistance. In this study, HCT116 and HT-29 cells were used as research subjects. Firstly, methyl thiazolyl tetrazolium(MTT) assay and colony formation assay were used to detect and analyze the effect of HSYA on the proliferation of CRC cells. Secondly, the effect of HSYA on the cell cycle in CRC cells was analyzed by cell cycle assay. Furthermore, the effect of HSYA on the migration of CRC cells was analyzed by wound-healing assay and Transwell assay. Based on the above, the influences of HSYA on 5-FU chemoresistance of CRC cells and related molecular mechanisms were explored and analyzed. The results showed that HSYA significantly inhibited the proliferation and migration of CRC cells, and arrested the cell cycle in G_0/G_1 phase. In addition, HSYA significantly ameliorated the chemoresistance of CRC cells to 5-FU. The results of acridine orange staining and Western blot showed that the autophagy activity of CRC cells in the HSYA and 5-FU combined treatment group was significantly higher than that in the 5-FU single drug treatment group. As compared with the 5-FU single drug treatment group, the phosphorylation levels of protein kinase B(Akt) and mammalian target of rapamycin(mTOR) in the HSYA and 5-FU combined treatment group were significantly reduced, indicating that the Akt/mTOR signaling pathway in the combined treatment group was down-regulated in CRC cells. In conclusion, HSYA may upregulate autophagy activity through the Akt/mTOR signaling pathway, thereby inhibiting the proliferation and migration of CRC cells and ameliorating the chemoresistance to 5-FU.

Objective To compare the measurement differences between the skull 3D printed model and the real specimen under different CT scan slice thicknesses, and to explore the effect of slice thickness on the accuracy of the 3D printed model. Methods Eight normal skull specimens (marked as Nos. f-8) (group N) were used for CT scanning with different slice thicknesses, specifically 0.625 mm (group A),1.25 mm (group B) , and 2.5mm (group C) ,3.75 mm (group D) , and 5 mm (group E) , and then earned out 3D reconstruction and 3D printing respectively, and compared the anatomical reduction degree of the foramen magnum diameter, anterior clinoid distance, and butterfly wing distance of the 3D printed skull model. Results The reduction degree of anatomical structure of 3D printed skull model decreased with the increase of CT slice thickness. There was no significant difference in the accuracy of 3D model among groups A, B and C (P >0.05 ) . There was a high correlation between group A, B and C and group N ( P < 0 .05 ).The size indexes and statistical values of group A, B and C were similar. Conclusion CT slice thickness has a significant effect on the accuracy and reduction of the 3D printed skull model. The 3D printed model with thin slice data (0.625 mm,1.25 mm,2.5 mm) has higher accuracy and less difference.

Objective:To investigate the relationship between triglyceride glucose index (TyG) and body inflammation.Methods:The data were obtained from a baseline survey in population in Xi'an in natural population cohort study in northwest China established in 2018-2019. Based on TG and FPG, TyG/TyG-BMI was constructed to reflect insulin resistance (IR) in the body, and systemic immune-inflammation index (SII) reflecting inflammation in the body was constructed using neutrophil, lymphocyte, and platelet counts. A logistic regression model was used to explore the relationship between the TyG and the SII.Results:A total of 11 491 subjects were included in the analysis. After adjusting for covariates, each unit increase in the TyG increased the risk of high SII by 21% ( OR=1.21, 95% CI:1.12-1.30). The risk of high SII in the group with the TyG in Q4 was 1.34 times higher than that in the group Q1 ( OR=1.34, 95% CI:1.18-1.52). Both sensitivity analysis and subgroup analysis further confirmed the stability of the association between the TyG and the SII. In the population with a BMI ranging from 18.5 to 23.9 kg/m 2, for every unit increase in the TyG as a continuous variable, the risk for high SII increased by 31% ( OR=1.31, 95% CI:1.18-1.45). As a categorical variable, the risk for high SII in the Q4 group was 1.52 times higher than that in the Q1 group ( OR=1.52, 95% CI:1.27-1.83). In a population with BMIs ranging from 24.0 to 27.9 kg/m 2, for every unit increase in the TyG as a continuous variable, the risk for high SII increased by 20% ( OR=1.20, 95% CI:1.07-1.35), and there was no significant difference when it was a categorical variable. Conclusions:The increase in IR is closely related to the development of inflammation in the body, and BMI may regulate their relationship. Early prevention of elevated IR levels before overweight or obesity may have a positive effect on the control of inflammation in the body.

Objective: To investigate the association between muscle mass and quality of life in adults in Shaanxi adults. Methods: The data in this analysis were part of the baseline survey of the Regional Ethnic Cohort Study in Northwest China from June 2018 to May 2019 in Shaanxi Province. The participants' quality of life, including physical component summary (PCS) and mental component summary (MCS), was assessed by the 12-Item Short Form Survey, and the Body Fat Determination System measured muscle mass. A logistic regression model with adjustment for confounding factors was established to analyze the association between muscle mass and quality of life in different genders. Further, sensitivity and subgroup analyses were conducted to explore its stability. Finally, a restricted cubic spline was employed to investigate the dose-response relationship between muscle mass and quality of life in different genders. Results: A total of 20 595 participants were included, with an average age of 55.0, and 33.4% were male. After controlling for potential confounders, compared with the Q₁ group, the risk of low PCS was reduced by 20.6% (OR=0.794, 95%CI: 0.681-0.925) and the risk of low MCS was lower reduced by 20.1% (OR=0.799, 95%CI: 0.689-0.926) in female Q₅ groups. Compared with the Q₁ group, the risk of low PCS was reduced by 24.4% (OR=0.756, 95%CI: 0.644-0.888) in the male Q₂ group. However, no significant association between muscle mass and MCS in males has been found. In females, restricted cubic spline analysis showed a significant linear dose-response relationship between muscle mass and PCS and MCS. Conclusions: There is a positive association between muscle mass and quality of life in Shaanxi adults, especially females. With the increase in muscle mass, the physical and mental functions of the population continue to improve.
