Objective To study the proteomic profiling of lung and colon during lung injury induced by lipopolysaccharide(LPS).Methods Mice were divided into four groups:the control,LPS,LPS+ Platycodonis Radix(PR)and LPS+ Rhei Radix et Rhizoma(RRR).LPS was injected into the lungs through trachea,and the drugs were given by intragastric injection.The mice were weighed,the faeces of each mouse were determined,and the lungs and colon were isolated for analysis of pathophysiological changes and proteomics.Results ①After 7 days of LPS,the weight of mice decreased,the lung showed inflammatory changes,and the faeces increased.Both PR and RRR can improve the inflammation.②There are lot of proteins was increased in lung mainly involved in gene transcription and in colon mainly involved in mitochondrial,endoplasmic reticulum and metabolism,etc.The up-regulated proteins shared by both lung and colon were involved in myoprotein contraction.PR can inhibit the up-regulated protein more than RRR in lung.③There are large number of proteins were down-regulated in lung involved in cell membrane and in colon involved in nucleic acid binding and ATP binding.The down-regulated proteins shared by both lung and colon were involved in endoplasmic reticulum,nucleic acid binding and cell membrane,etc.The down-regulated proteins in lung by PR are more than those by RRR,which is involved in endoplasmic reticulum,cell membrane,etc.Conclusion LPS-induced lung injury can cause changes in the expression of protein in lung and colon proteins,and the increase in the expression of myoprotein contraction genes may be one of the molecular mechanisms related to lung and colon.

Nituzumab is a humanized IgG monoclonal antibody against EGFR. The purpose of this study is to investigate the toxicity and efficacy of concurrent chemoradiotherapy combined with nituzumab for locally advanced esophageal cancer.Methods:We retrospectively reviewed the clinical data of locally advanced esophageal cancer who were treated with concurrent chemoradiotherapy combined with nituzumab in Peking University Cancer Hospital from June 2015 to June 2020. Kaplan- Meier method was used for analysis. Results:Thirty Patients were enrolled this study.After a median follow-up of 22.5 months, The objective response rate was 93%. The 1-year, 2-year, 3-year overall survival rates were 83%, 57% and 41%, with the progression-free survival rates 75%, 47% and 32%, with the local-recurrence free survival rates 83%, 53% and 37%, with the metastasis-free survival rates 75%, 51% and 36%, respectively.The incidence of grade≥3 hematological toxicity was 32%. There were 16% patients experiencing grade≥3 esophagitis.Conclusion:The preliminary result of concurrent chemoradiotherapy combined with nituzumab is effective and safe for patients with locally advanced esophageal cancer.

Objective:
To understand the characteristics and trends of colorectal cancer incidence and mortality in Lishui residents from 2014 to 2018,so as to provide basis for the development of prevention and treatment measures of colorectal cancer.
Methods :
The incidence and mortality data of colorectal cancer in Lishui from 2014 to 2018 were collected through the information management system of chronic disease surveillance in Zhejiang Province. The incidence,mortality and annual percentage change(APC)of colorectal cancer were calculated and analyzed in different genders,ages and regions were analyzed.
Results:
From 2014 to 2018,there were 4 403 new cases of colorectal cancer in Lishui,with the crude and standardized incidence rate of 34.89/100 000 and 20.99/100 000,respectively. There were 2 369 deaths,with a crude mortality rate of 18.77/100 000 and a standardized mortality rate of 10.17 /100 000. The crude incidence rate and crude mortality rate in males were higher than those in females(39.71/100 000 vs. 29.77/100 000,21.31/100 000 vs. 16.08/100 000,both p<0.05). There were no statistically significant differences between urban and rural residents in the crude incidence rate and crude mortality rate(37.24/100 000 vs. 34.44/100 000,19.75/100 000 vs. 18.45/100 000,both p<0.05). The crude incidence rate and crude mortality rate increased with age. The APC of the mortality rate of colorectal cancer among urban residents was 11.31%,showing an increasing trend from 2014 to 2018(p<0.05).
Conclusion
The incidence and mortality of colorectal cancer are high in Lishui,and the focus groups are men,people aged over 40 years and urban residents.

There have been many reports on berberine (BBR) effect of the inhibition on gut bacteria,but more from the protein level.In view of the preference of BBR for DNA binding,we here investigated the expression of BBR from the transcriptional expression level of the gene.The results showed that BBR had a higher affinity for UP element of Escherichia coli (E.coli) gene,and the transcription initiation region of this element contained TATA base sequence.The expression of genes sulA,recA and 16S which contain the genes of the UP element regulatory elements in the upstream of the promoter could be suppressed by BBR,and the expression of lpxC,secG and mutT which did not contain the genes of the UP element regulatory elements in the upstream of the promoter could not be inhibited by BBR.It is shown that the TATA sequence is the target of BBR.This result provides a new perspective for exploring the effect of BBR's inhibition of microbiota from gene transcription.

Berberine (BBR) is known as a classic drug for intestinal infection treatment.BBR inhibits intestinal bacteria,which is the core of its role in the treatment of intestinal infection.With the survival of local intestinal bacteria and its related metabolites on the physiological and pathological functions of the body continue to recognize the impact of it,more and more literatures have presented the effect of BBR through the impact of intestinal bacteria on the body glycol-lipid metabolism,even brain function.This allows us to re-understand the pathophysiology of BBR in inhibiting gut microbiome.In this paper,the antibacterial activity of BBR was reviewed and analyzed.The possible molecular target of BBR was analyzed according to the characteristics of prokaryotes gene expression,which was helpful to the in-depth study of BBR on intestinal bacteria.Thus,a more comprehensive understanding of the pharmacological effects of BBR is given.

This study was aimed to observe effect of pomegranate leaf tannin and ellagic acid on primary rat adipocyte differentiation and lipid metabolism-related factor expression. Primary rat preadipocyte was in vitro cultured to observe the effect of pomegranate leaf tannin and ellagic acid on lipid fat cells as well as mRNA expression of its related factor. The results showed that pomegranate leaf tannin and ellagic acid had obvious inhibition effect on fat formation in fat cells. It had certain inhibition effect on activities of lipoprotein lipase (LPL) and glucose-3-phosphate dehydrogenase (GPDH). It promoted fat decomposition and reduced intracellular lipid content. It upregulated PPARγ and fatty acid-binding protein (aP2). It downregulated obese (ob) gene level. It was concluded that pomegranate leaf tannin can inhibit fat generation of fat cells and promote fat metabolism. Ellagic acid was its main active ingredient, which had the same effect as pomegranate leaf tannin.

This study was aimed to observe the effect ofpomegranate leaf tennis and Ananas coumosus leaf phenols on the growth of lactating mice through breast milk. Intragastric administration of different doses of drug was given to maternal mice. The general condition of newborn mice, body weight, tail length and organ coefficient of liver-related factors regulating the expression of lipid metabolism were observed. The results showed that both pomegranate leaf tennis and A. coumosus leaf phenols can obviously affect the growth and development of newborn mice through breast milk. And the effect of pomegranate leaf tennis was stronger than A. coumosus leaf phenols. Meanwhile, it obviously downregulated the expression of liver-related lipid metabolism enzymes in newborn mice. It was concluded that pomegranate leaf tennis and A. coumosus leaf phenols can affect the growth and development of newborn mice through breast milk. Its effect was related to the influence of lipid metabolism enzyme in the liver. Attention should be paid on taking this medication during lactation. Its clinical significance still required in-depth study.
