Objective:To investigate the clinicopathological characteristics and prognosis of pancreatic cancer (PC) patients with fatty pancreas (FP).Methods:The retrospective cohort study was conducted. The clinicopathological data of 116 patients with PC who underwent surgery at Qilu Hospital of Shandong University from January 2013 to January 2022 were collected. There were 85 males and 31 females, aged 60(54,65)years. Observation indicators: (1) clinicopathological characteristics of PC patients with FP; (2) influencing factors for FP in PC patients; (3) prognosis of PC patients with FP. Comparison of count data between groups was conducted using the Pearson chi-square test. Multivariate analysis was conducted using the Logistic regression model. The Kaplan-Meier method was used to plot survival curve and calculate survival rate, and Cox proportional hazard model was used for survival analysis.Results:(1) Clinicopathological characteristics of PC patients with FP. Of the 116 PC patients, there were 43 cases with FP and 73 cases without FP. Cases with tumor location at pancreatic head were 36 in PC patients with FP and 46 in PC patients without FP. Cases with tumor location at pancreatic body or tail were 7 in PC patients with FP and 27 in PC patients without FP. Cases with high-density lipoprotein cholesterol ≥1.04 mmol/L were 14 in PC patients with FP and 34 in PC patients without FP. Cases with dyslipidemia were 33 in PC patients with FP and 36 in PC patients without FP. There were significant differences in tumor location, high-density lipoprotein cholesterol and plasma lipid between PC patients with and without FP ( χ2=5.600, 4.588, 5.165, P<0.05). (2) Influencing factors for FP in PC patients. Results of multivariate analysis showed that no correlation was found between tumor location, high-density lipoprotein cholesterol, plasma lipid and FP in PC patients ( P>0.05). (3) Prognosis of PC patients with FP. Eighty of the 116 PC patients were followed up for 30.8(15.1,57.5)months, with the median overall survival time of 24.0 months. Among them, 54 patients with FP had a median overall survival time of 19.5 months, 26 patients without FP had a median overall survival time of 24.6 months, showing no significant difference in survival between them ( hazard ratio=1.031, P>0.05). Conclusions:There are differ-ences in tumor location, high-density lipoprotein cholesterol and plasma lipid between PC patients with and without FP, but no correlation is found between the above indicators and FP in PC patients. There is no significant difference in prognosis between patients with and without FP.

Liver is the most common metastatic site for colorectal cancer (CRC), there is no satisfied approach to treat CRC liver metastasis (CRCLM). Here, we investigated the role of a polycomb protein BMI-1 in CRCLM. Immunohistochemical analysis showed that BMI-1 expression in liver metastases was upregulated and associated with T4 stage, invasion depth and right-sided primary tumor. Knockdown

This study aimed at evaluating the quality of the precise powder decoction pieces (PPDP) of L.japonicae Flos (LJF) compared with the traditional commercial slices with chemical fingerprint methods and DNA molecular identification technology.Different specifications of PPDP were prepared,their dry extract contents were in contrast with that of commercial slices.The three batches of commercial slices were collected,and the content uniformity,fingerprint and similarity evaluation before and after the mixing and pulverization were studied by HPLC-DAD and DNA sequence alignment.As a result,the paste rate of PPDP was slightly higher than that of the traditional commercial slices.The dissolution of chlorogenic acid of PPDP was higher than that of the traditional commercial slices.RSD of inter-assay dissolutions of chlorogenic acid of commercial slices was 11.93％,which was reduced to 8.29％ after mixing and preparing into PPDP.The fingerprint showed that the slimilarity of the fringerprint of the mixed and powdered LJF was elevated with 7 common peaks.All the common peaks were increased at different levels.In conclusion,compared with traditional commercial slices of LJF,PPDP apparently improved the dissolution rate and the quality uniformity,indicating that the boiled powder of CRP obviously presented vantages in clinic.

Nicotinamide adenine nucleotide (NADH), the key cofactor in the metabolic network, plays an essential role in biochemical reaction and physiological function of industrial strains. Manipulation of NADH availability and form is an efficient and easy way to redirect the carbon flux to the target metabolites in industrial strains. We reviewed the physiological function of NADH. Detailed strategies to manipulate NADH availability are addressed. NADH manipulation to enhance metabolic function of industrial strains was discussed and potential solutions were suggested.
