Hypertriglyceridemia-associated acute pancreatitis is an inflammatory disorder of exocrine pancreas caused by metabolism disturbances of triglyceride-rich lipoproteins.Currently,hypertriglyceridemia-associated acute pancreatitis is characterized by an escalating incidence rate,a tendency for more severe cases,and a lack of therapeutic drugs.Traditional Chinese medicine has distinct advantages in treating this disease,but its theoretical framework has not yet been established.Hypertriglyceridemia-associated acute pancreatitis manifests itself as a febrile disease,aberrant accumulation of fat and turbidity may stem from dietary imbalances and visceral dysfunction in ordinary individuals.The prolonged accumulation of fat and turbidity can transform into turbid pathogen,subsequently engendering heat,constituting a pivotal pathogenic factor.Throughout the progression of the disease,the fiery pathogen consumes the fat and turbidity,resulting in the generation of toxic heat,which is a crucial mechanism in the exacerbation of the disease severity.Thus,this article posits therapeutic principles aimed at averting the transformation of fat and turbidity into turbid pathogen and counteracting toxic heat in this disease.This article reviews two key theories from traditional Chinese medicine classics relevant to hypertriglyceridemia-associated acute pancreatitis:the theory of fat-turbidity associated with hypertriglyceridemia and the febrile disease related to acute pancreatitis.Combining these traditional theories with modern research on the mechanisms that intensify hypertriglyceridemia-associated acute pancreatitis and the corresponding targets of traditional Chinese medicine,it suggests that the pathogenesis of"fat-turbidity-toxic heat"serves as the theoretical basis of traditional Chinese medicine for the aggravated severity of hypertriglyceridemia-associated acute pancreatitis.The article aims to offer new insights for the treatment of hypertriglyceridemia-associated acute pancreatitis.

OBJECTIVE To explore the neuroprotective effect of sodium aescinate on rats with Parkinson’s disease by regulating the silent information regulator 1 (SIRT1)/nuclear factor-κB (NF-κB) signaling pathway. METHODS The Parkinson’s disease rat model was constructed by using 6-hydroxydopamine injection method. Forty-eight rats successfully modeled were randomly divided into model group, sodium aescinate low-dose group (1.8 mg/kg), sodium aescinate high-dose group (3.6 mg/kg), sodium aescinate+EX527 (sodium aescinate 3.6 mg/kg+SIRT1 inhibitor EX527 5 mg/kg) group, with 12 rats in each group. Another 12 healthy rats were selected as the sham operation group. Each group was injected with the corresponding drug solution intraperitoneally, once a day, for 21 consecutive days. Twenty-four hours after the end of the last administration, the motor and cognitive functions of rats were detected, and the morphology of neurons in the substantia nigra and CA1 region of hippocampal tissue were observed. The content of dopamine (DA) in the nigrostriatal and the expression levels of tyrosine hydroxylase (TH) and α-synuclein (α-Syn) in the substantia nigra were detected. The serum levels of pro-inflammatory factor [interleukin-6 (IL-6), IL-18], anti-inflammatory factor (IL-10), and the expression levels of SIRT1, phosphorylated NF-κB p65 (p-NF-κB p65) and NF- κB p65 protein in nigrostriatal were detected. RESULTS Compared with sham operation group, the neurons in the substantia nigra and CA1 region of hippocampal tissue were seriously damaged in model group; the number of rotations, escape latency, the expression levels of α-Syn in substantia nigra, the levels of serum pro-inflammatory factors, the relative expression ratio of p-NF- κB p65 and NF-κB p65 protein in nigrostriatal were increased or prolonged significantly (P<0.05); the target quadrant residence time, the content of DA in nigrostriatal, the expression level of TH in substantia nigra, the serum level of anti-inflammatory factor, and the expression level of SIRT1 protein in substantia nigra striatum were significantly decreased or shortened (P<0.05). Compared with model group, the damage degrees of neuron in sodium aescinate groups were alleviated, and the quantitative indicators were significantly improved, which were more significant in the high-dose group (P<0.05); EX527 could reverse the improvement effect of high-dose sodium aescinate (P<0.05). CONCLUSIONS Sodium aescinate can inhibit the activation of NF-κB signal by up-regulating the protein expression of SIRT1, thereby reducing the neuroinflammation of rats with Parkinson’s disease, improving the motor and cognitive dysfunctions, and finally playing a neuroprotective role.

Objective:To construct a risk prediction and assessment system for incisional infection after spinal surgery.Methods:Based on the failure mode and effect analysis (FMEA), risk factors and assessment indicators of postoperative incisional infection in spinal surgery were sorted out through literature search followed by expert consultation using the Delphi expert consultation method. After three-level assessment indicators were selected according to their importance and expert opinions and assigned by different scores, a risk prediction and evaluation system was constructed for postoperative incisional infection after spinal surgery.Results:The 2 rounds of expert consultation questionnaire resulted in an effective response rate of 100%. The degree of expert consultation authority was 0.85, showing high reliability; the Kendall coordination coefficients of expert consultation ranged from 0.525 to 0.686, showing good coordination ( P<0.05). The three-level assessment indicators consisted of 3 primary, 18 secondary and 54 tertiary ones. After statistical analyses of the important risk indicators selected which consisted of 6 preoperative evaluation ones and 18 postoperative evaluation ones, 6 preoperative and 12 postoperative predictive indicators were obtained. The values of risk priority number (RPN) were calculated for high, medium and low risks for postoperative incisional infection using a semi-quantitative method. Conclusion:A self-designed system has been constructed for risk prediction and assessment of incisional infection after spinal surgery based on expert consultation and FMEA method.
