Hepatic encephalopathy is a difficult and critical disease with rapid progression and limited treatment methods in the field of liver disease， and it is urgently needed to make breakthroughs in its pathogenesis. Selection of appropriate prevention and treatment strategies is of great importance in delaying disease progression and reducing the incidence and mortality rates. This article reviews the theory of “turbid toxin pathogenesis” and related prevention and treatment strategies for hepatic encephalopathy in traditional Chinese medicine/Zhuang medicine， proposes a new theory of “turbid toxin pathogenesis”， analyzes the scientific connotations of “turbid”， “toxin”， and the theory of “turbid toxin pathogenesis”， and constructs the “four-step” prevention and treatment strategies for hepatic encephalopathy， thereby establishing the new clinical prevention and treatment regimen for hepatic encephalopathy represented by “four prescriptions and two techniques” and clarifying the effect mechanism and biological basis of core prescriptions and techniques in the prevention and treatment of hepatic encephalopathy， in order to provide a reference for the prevention and treatment of hepatic encephalopathy.

ObjectiveTo evaluate the efficacy and safety of Lianhua Qingke tablets in the treatment of acute bronchitis in children with the syndrome of phlegm-heat obstructing lung. MethodA randomized， open， parallel controlled， and multi-center clinical study was conduted. Children with acute bronchitis （syndrome of phlegm-heat obstructing lung） were randomly assigned to an observation group and a control group. The control group received routine basic treatment， and the observation group was treated with Lianhua Qingke Tablets on the basis of routine basic treatment. After 7 days of treatment， the clinical efficacy， TCM efficacy， time to symptom disappearance， time to cough disappearance， and clinical safety were compared between the two groups. ResultA total of 248 children were included （124 in the observation group and 124 in the control group）. After 7 days of treatment， the total response rate in terms of clinical efficacy in the observation group was 96.8% （120/124）， which was higher than that （90.3%， 112/124） in the control group （Z=-5.034， P<0.01）. The total response rate in terms of TCM syndrome in the observation group was 97.6% （121/124）， which was higher than that （93.5%， 116/124） in the control group （χ²=-5.326， P<0.01）. The scores of physical signs and TCM symptoms in the observation group were lower than those in the control group at the time of taking medicine for 3 days and 7 days （P<0.01）. The time to symptom disappearance and the time to cough disappearance in the observation group were shorter than those in the control group （P<0.01）. Drug-related adverse reactions occurred in neither group. ConclusionLianhua Qingke tablets demonstrate a definite effect on acute bronchitis in children with the syndrome of phlegm-heat blocking lung. The tablets can significantly shorten the course of disease and relieve cough and TCM symptoms， with high safety， which is worthy of clinical application and promotion.

In recent years,the morbidity and mortality of hepatocellular carcinoma(HCC)have been increasing worldwide,and the treatment strategies for HCC are still insufficient,which highlights the importance of exploring the pathogenesis and progression of HCC.Transient receptor potential(TRP)pathway is an important non-selective cation pathway,which is closely related to inflammatory response and sensory conduction.At present,a number of studies have shown that TRP pathway is also involved in the occurrence and development of HCC,inducing HCC invasion and migration.However,the overall potential mechanism and possible signal transduction pathways of TRP pathway in HCC remain unclear.Therefore,this article discusses the abnormal expression of TRP pathway in HCC,and reviews the key biological events of TRP pathway involved in the formation and progression of HCC,such as chronic liver inflammation-fibrosis progression,HCC cell proliferation,migration,apoptosis and HCC stem cell generation,and looks forward to its application prospect in HCC treatment.The aim is to better un-derstand the significance of TRP pathway in HCC,help to find new therapeutic targets and effective drugs,and open up a new situation for future clinical treatment.

Acute-on-chronic liver failure (ACLF) is a life-threatening disease with a high risk of multiple organ failure, sepsis, and death. ACLF activates innate and acquired immune responses in human body and thus leads to the progression of persistent systemic inflammatory response syndrome and multiple organ dysfunction, leading to the high mortality rate of this disease. Dysregulated immune response plays a key role in disease progression, and immunotherapy may help to target immune-mediated organ damage and inhibit the progression of liver failure. This article reviews the role and mechanism of drugs and means with a potential immune regulatory effect in ACLF, in order to provide a reference for immunotherapy for ACLF.

Liver failure is a syndrome of severe liver diseases commonly seen in clinical practice, and it has a high mortality rate and thus becomes one of the critical diseases in internal medicine. Massive hepatocyte death and the extent of hepatocyte death exceeding the liver’s regenerative capacity are considered the core events in the development and progression of liver failure, and direct injury and immune-mediated inflammatory injury are the two main factors in this process. An increasing number of evidence has shown that host immune response and inflammatory cascade play an important role in the pathogenesis of liver failure. This article reviews the mechanism of action of immunoregulation (congenital and adaptive) and inflammatory injury (inflammation inducers, receptor cells, and inflammatory mediators) in the process of hepatic failure, as well as the interactions between immune response and immune cells and between inflammatory response and inflammatory factors, in order to help understand the pathogenesis of liver failure and provide new ideas for the diagnosis and treatment of liver failure and drug research and development.

OBJECTIVE：To estab lish“TCM Data Analysis Platform Based on Strategy Pattern ”（TCMDP），and to analyze the medication rules of TCM prescription against primary hepatic carcinoma （PHC），so as to provide reference for TCM prescription screening. METHODS ：According to the idea of strategy pattern ，TCMDP software was developed ，and the frequency statistics，association，clustering，classification and other methods and the different algorithms covered were encapsulated. Effective TCM prescriptions against PHC were collected and screened from 4 tertiary-grade class-A hospitals in Nanchang city and CNKI ， PubMed. A database of prescriptions for PHC （PDOPHC）was established ，and TCM prescriptions in the data base were put into TCMDP. Clustering algorithm modified by CMC-DD ，modified WD-Get Rules algorithm after merging depth and width search and frequency statistics were used to analyze the distribution of prescription syndrome. Taking phlegm-blood stasis syndrome type （TYPHC）as example ，data mining was carried out on drug efficacy category ，four properties ，five flavors and channel tropism ， drug property combination ，key couplet medicines and key drug combination. RESULTS ：A total of 907 TCM prescriptions against PHC were collected ，mainly involving 10 syndrome types ，such as phlegm-blood stasis syndrome ，deficiency of the vital essential and blood stasis syndrome and liver and spleen blood stasis syndrome. TCM related to TYPHC commonly used in pre- scriptions were tonifying deficiency medicine ， phlegm-re- solving medicine ，promoting blood circulation and removing blood stasi s medicine ，etc．Four properties were mostly cold ，warm and calm ；the five flavors were most ly swe et，bitter and pungent ；channel tropism were mostly spleen ，liver，stomach， lung，heart and kidney ；drug combination were mostly warming-sweet-spleen ，warming-pungent-spleen and cold-bitter-liver ，etc.； there were 36 couplet medicines with frequency ≥30 times；there were 31 strong association rules and 8 key drug combinations in the prescriptions. WD-Get Rules results showed that in the TCM prescriptions against PHC ，Atractylodes macrocephala ，Codonopsis pilosula，Poria cocos and Glycyrrhiza uralensis were in the key position. They were often combined with many kinds of drugs ， which were related to the effect of Sijunzi decoction on strengthening Qi and tonifying spleen. CMC-DD results showed that therapy for TYPHC focused on strengthening the spleen and stomach ，replenishing Qi and blood ；and at the same time ，it treated TYPHC with phlegm-blood stasis syndrome from multiple angles ，such as soothing the liver and regulating Qi ，eliminating phlegm ，clearing heat and detoxification ，promoting blood circulation and nourishing Yin. CONCLUSIONS ：Clinical treatment of TYPHC mainly adopts the methods of invigorating the spleen and replenishing Qi ，soothing the liver and regulating Qi ，promoting blood circulation and removing blood stasis ，which conforms to the medication principle of “strengthening the body and eliminating pathogenic factors”. The application of TCMDP can realize the data mining and analysis of TCM in multi-level and multi-directional way ， which provides a new and effective way for the mining and research of compatibility rules of TCM prescriptions.

Objective: To investigate the distribution of bla_KPC gene in Lishui and to analyze the molecular epidemiological characteristics of Klebsiella pneumoniae (K.pneumoniae) bla_KPC gene. Methods: From 2010 to 2016, all of the non-repetitive K. pneumoniae carbapenemase (KPC)-producing isolates in Lishui Municipal Central Hospital were collected. They were identified with VITEK 2 Compact system and typed by multilocus sequence typing (MLST). Plasmids were classified based on the DNA sequences of replication initiators. Transposons were detected by PCR. Locations of bla_KPC gene were verified through complete sequencing of the plasmids by next-generation sequencing (NGS). Results: A total of 125 strains were collected. K. pneumoniae strains accounted for 88.8% (111) and among them, 103 were ST11 type. IncF plasmids were detected in 48.6% of K. pneumoniae strains and most of them carried mutant Tn1721/Tn4401 chimera (48/54 isolates). Untypable plasmids were discovered in 50.5% of isolated strains and most of them were positive for the wild-type chimera (54/56 isolates). IncF-positive strains isolated during the period of 2011 and 2013 accounted for 94.4%, followed by a dramatic decrease. However, 76.8% of the strains harboring untypable plasmids were isolated from 2014 to 2016 and the number increased year by year. Conclusion K. pneumoniae of ST11 type was the main cause of bla_KPC gene dissemination in Lishui area. Strains carrying the IncF plasmids integrated with the mutant Tn1721/Tn4401 chimera and the untypable plasmids with the wild-type chimera were prevalent before and after 2014, respectively.

Objective To analyze the drug resistance phenotype and genetic background of New Delhi metallo-β-lactamase (NDM)-producing bacterial strains in Lishui area of Zhejiang province.Methods The imipenem-resistant Enterobacteriaceae strains were isolated from January 2012 to December 2016 in Lishui Municipal Central Hospital of Zhejiang Province.Mrieux Vitek 2 Compact system was used to identified strains and PCR was used to screen for blaNDMgene.Susceptibility was detected by K-B method and MICs were obtained by Vitek 2 with GN13 cards.Plasmids typing was carried out by DNA sequencing of the replication initiator with the transconjugates as templates.The blaNDMgenetic contexts were detected by PCR and complete genome sequencing.Results A total of 102 strains of carbapenem-resistant enterobacteria (CRE), mainly Escherichia coli and Enterobacter cloacae, were isolated, of which 15 were positive for blaNDMwith a positive detection rate of 14.7%.The resistance rate to β-lactam antibiotics was 100%, and the resistance rates to aztreonam, compound sulfamethoxazole , tobramycin and gentamicin were all ＞80%;and the resistance rate to quinolones was ＞50%.Among the 15 NDM-producing strains , 12 strains were positive for Hodge test, and 2 strains of Enterobacter cloacae and 1 strain of Escherichia coli were negative. There were 11 strains of blaNDM-1and 4 strains of blaNDM-1.A variety of plasmid types such as IncX 3, IncFIIγ and IncA/C were detected, and 4 blaNDM-5genes were located in the IncX3 plasmid.Four blaNDMsurrounding gene structures were found, of which 8 blaNDM-1genes were located in ISAb125-hyp-blaNDM-1-bleMBL-TrpF-DsbC-IS26, while blaNDM-5was located in IS3000-IS5-blaNDM-5-bleMBL-TrpF-DsbC-IS26 structure, and the former was reported for the first time in China.Conclusion NDM-producing bacterial strains in Lishui area are prevalent at a low level and have high sensitivity to fosfomycin and polymyxin .The blaNDMgene may have multiple sources, but IncX3 plasmid is still the main source for gene transfer.Some new types of blaNDM-1 gene structure have been also found in this study.
