Analysis of the correlation between metabolic syndrome and recurrent acute pancreatitis / 中华消化杂志

Objective:To investigate the correlation between metabolic syndrome (MS)and recurrent acute pancreatitis (RAP).Methods:From June 1, 2012 to June 1, 2023, 463 patients with RAP (recurrent group) who visited the First Affiliated Hospital of Chongqing Medical University were retrospectively collected. The clinical data of 463 patients without RAP (non-recurrent group) during the same period were randomly selected. The patients in the recurrence group were treated at the First Affiliated Hospital of Chongqing Medical University for both initial acute pancreatitis and RAP. The differences in the proportion of patients combined with MS and its components (obesity (body mass index ≥25 kg/m 2), fasting blood triglyceride (TG) ≥1.7 mmol/L, hypertension, hyperglycemia, fasting blood high-density lipoprotein cholesterol (HDL-C) <1.04 mmol/L) between the two groups were analyzed by Chi-square test. Binary logistic regression analysis was used to identify the risk factors of acute pancreatitis recurrence. Results:Among the 463 patients in the recurrent group, there were 221 patients (47.7%) with MS, 276 patients (59.6%) with obesity, 223 patients (48.2%) with hypertension, 185 patients (40.0%) with hyperglycemia, and 365 patients (78.8%) with fasting blood TG ≥1.7 mmol/L. Among the 463 patients in the non-recurrence group, there were 95 patients (20.5%) with MS, 245 patients (52.9%) with obesity, 115 patients (24.8%) with hypertension, 92 patients (19.9%) with hyperglycemia, and 301 patients (65.0%) with fasting blood TG ≥ 1.7 mmol/L. The percentages of MS, obesity, hypertension, hyperglycemia, and fasting blood TG ≥1.7 mmol/L of the recurrent group were all higher than those of the non-recurrent group, and the differences were statistically significant ( χ2=76.27, 4.22, 54.35, 44.55, 21.90; P<0.001, =0.040, <0.001, <0.001, <0.001). There was no statistically significant difference in the percentage of patients with fasting blood HDL-C <1.04 mmol/L between the recurrent group and the non-recurrent group (68.5%, 317/463 vs. 65.4%, 303/463, P>0.05). The results of binary logistic regression analysis showed that combined with MS ( OR=3.538, 95% confidence interval (95% CI) 2.647 to 4.728), hypertension ( OR=2.700, 95% CI 2.025 to 3.602), hyperglycemia ( OR=2.228, 95% CI 1.633 to 3.039), and fasting blood TG ≥1.7 mmol/L ( OR=1.757, 95% CI 1.276 to 2.421) all significantly increased the risk of acute pancreatitis recurrence ( P<0.001, <0.001, <0.001, =0.001). Obesity was not an independent risk factor for RAP ( OR=0.967, 95% CI 0.727 to 1.286, P=0.816). Conclusion:The combination of MS, hypertension, hyperglycemia, and fasting blood TG ≥1.7 mmol/L are independent risk factors for RAP.

Objective: To analyze the current status of clinical treatment and factors influencing postoperative mortality in infants with critical congenital heart disease (CCHD) in China, optimize the perioperative management of CCHD, and provide a new scientific basis for clinical decision-making for the optimal management of these patients. Methods: This is a retrospective single-center study. Infants diagnosed with CCHD in Guangdong Provincial People's Hospital from January 2017 to December 2019 (aged 0-1 years at admission) were enrolled. General clinical information, inpatient treatment information, prognosis and complications were collected and analyzed. Multivariate logistic regression analysis was used to explore the independent risk factors of postoperative death in infants with CCHD. Results: A total of 826 infants with CCHD were included, including 556 males (67.3%) and the age at first admission was 51.0 (5.0,178.3) days. 264 (32.0%) cases were tetralogy of Fallot and 137 (16.6%) cases were total anomalous pulmonary venous return. 195 cases (23.6%) were diagnosed prenatally. 196 cases (23.7%) were treated with prostaglandin. The preoperative invasive ventilation time was 0 (0, 0) hour, and the postoperative invasive ventilation time was 95.0 (26.0, 151.8) hours. A total of 668 cases (80.9%) underwent surgical treatment. The age was 100.5 (20.0, 218.0) days during operation and the operation time was 190.0 (155.0, 240.0) hours. Sixty-two cases (7.5%) received medical treatment, and 96 cases (11.6%) gave up treatment. A total of 675 cases (81.7%) were discharged with improvement, 96 cases (11.6%) were discharged after giving up treatment, 55 cases (6.7%) died and 109 cases (13.2%) were readmitted within one year. Complications occurred in 565 (68.6%) cases, including pneumonia in 334 cases (40.4%) and cardiac arrhythmias in 182 cases (22.0%). Multifactorial analysis showed that delayed chest closure (OR=49.775, 95%CI 3.291-752.922, P=0.005), prolonged post-operative invasive ventilator ventilation (OR=1.003, 95%CI 1.000-1.005, P=0.038) and cardiac hypoplasia syndrome (OR=272.658, 95%CI 37.861-1 963.589, P<0.001) were the independent risk factors for mortality in CCHD infants post-operation. Conclusions: Tetralogy of Fallot and total anomalous pulmonary venous return account for the majority of infants with CCHD. The proportion of infants diagnosed prenatally was less than 1/4. The majority CCHD infants received surgical treatment. The main complications are pneumonia and arrhythmia. Delayed chest closure, prolonged postoperative invasive ventilator ventilation and low cardiac output syndrome are the independent risk factors for postoperative death in infants with CCHD.

Two New Species in the Family Cunninghamellaceae from China

The species within the family Cunninghamellaceae are widely distributed and produce important metabolites. Morphological studies along with a molecular phylogeny based on the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA revealed two new species in this family from soils in China, that is, Absidia ovalispora sp. nov. andCunninghamella globospora sp. nov. The former is phylogenetically closely related to Absidia koreana, but morphologically differs in sporangiospores, sporangia, sporangiophores, columellae, collars, and rhizoids. The latter is phylogenetically closely related to Cunninghamella intermedia, but morphologically differs in sporangiola and colonies. They were described and illustrated.

Intra-Spinal Bone Marrow Mononuclear Cells Transplantation Inhibits the Expression of Nuclear Factor-kappaB in Acute Transection Spinal Cord Injury in Rats

OBJECTIVE: To assess the effect of bone marrow mononuclear cells (BMMNCs) transplantation in the expression of nuclear factor-kappaB (NF-kappaB) in spinal cord injury (SCI) in rats. METHODS: BMMNCs were isolated from tibia and femur by a density gradient centrifugation. After establishment of acute transection SCI, rats were divided into experiment (BMMNCs), experiment control (0.1 M PBS infused) and sham surgery groups (laminectomy without any SCI). Locomotor function was assessed weekly for 5 weeks post-injury using BBB locomotor score and urinary bladder function daily for 4 weeks post-injury. Activity of NF-kappaB in spinal cord was assessed by immunohistochemistry and reverse transcriptase polymerase chain reaction. RESULTS: At each time point post-injury, sham surgery group had significantly higher Basso, Beattie, Bresnahan locomotor and urinary bladder function scores than experiment and experiment control group (p<0.05). At subsequent time interval there were gradual improvement in both experiment and experiment control group, but experiment group had higher score in comparison to experiment control group (p<0.05). Comparisons were also made for expression of activated NF-kappaB positive cells and level of NF-kappaB messenger RNA in spinal cord at various time points between the groups. Activated NF-kappaB immunoreactivity and level of NF-kappaB mRNA expression were significantly higher in control group in comparison to experiment and sham surgery group (p<0.05). CONCLUSION: BMMNCs transplantation attenuates the expression of NF-kappaB in injured spinal cord tissue and thus helps in recovery of neurological function in rat models with SCI.
