Objective:
To know the pre-treatment drug resistance ( PDR ) status of newly reported human immunodeficiency virus type 1 ( HIV-1 ) infected individuals in Wenzhou, so as to provide guidance for antiretroviral therapy ( ART ).
Methods:
Totally 232 plasma samples of newly reported HIV-1 infected individuals who had not received ART were collected in Wenzhou in 2019. Virus ( HIV-1 ) RNA was extracted, followed by reverse transcription PCR and nested PCR to amplify the pol region and sequence. Resistance mutations and resistance to non-nucleoside reverse transcriptase inhibitors ( NNRTIs ), nucleoside reverse transcriptase inhibitors ( NRTIs ) and protease inhibitors ( PIs ) was analyzed.
Results:
The pol region sequences from 199 infected patients were obtained and the incidence of PDR was 8.04% ( 16/199 ). Eight genotypes were detected, including circulating recombinant forms ( CRFs ) CRF07_BC ( 47.24%, 94/199 ) and CRF01_AE ( 29.15%, 58/199 ) which were the dominant types. Two unique recombinant forms ( URFs ) were detected, namely URF( CRF01_AE/BC ) and URF( B/C ) . Thirty-one cases ( 15.58% 31/199 ) had drug-resistant mutations. For NNRTIs, NRTIs and PIs, 20 cases ( 64.52% ) , 2 cases ( 6.45% ) and 9 cases ( 29.03% ) with drug resistance mutations were detected, respectively. The resistance mutations to NNRTIs included K101E, K103N/R, V106I, E138K, V179D/E/T, Y181C, G190A and H221Y. Four cases each had two resistance mutations to NNRTIs. The resistance mutations to NRTIs were V75M and M184V. The resistance mutations to PIs were M46I, L33F and Q58E. For the newly released NNRTI drug Doravirine ( DOR ), two cases were found to have mutations of resistance.
Conclusions
The incidence of PDR among newly reported HIV-1 patients in Wenzhou is 8.04%, mainly caused by NNRTIs drug-resistant mutation. Resistance to the new drug DOR has emerged. The surveillance of drug resistance should continue to be strengthened.

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.

As a novel form of programmed cell death different from cell necrosis, apoptosis, and autophagy discovered in recent years, pyroptosis is characterized by cell membrane rupture and release of cell contents and proinflammatory factors mediated by gasdermin, thus leading to cell death. Pyroptosis signaling pathways can be classified into classical pathways dependent on caspase-1 and non-classical pathways dependent on caspase-4/5/11; the activation of caspase-1 in classical pathways depends on the function of inflammasome, while the direct activation of caspase-4/5/11 is observed in non-classical pathways, which leads to the lysis of gasdermin D and induce the formation of membrane pores, the maturation and release of interleukin-1β and interleukin-18, and the rupture of cell membrane to cause pyroptosis. Latest research has shown that pyroptosis plays an important role in the development and progression of chronic liver diseases. This article introduces the mechanism of pyroptosis and summarizes the role of pyroptosis in the development and progression of nonalcoholic fatty liver disease, alcoholic liver disease, viral hepatitis, liver cirrhosis, and hepatocellular carcinoma, in order to provide new ideas and methods for the prevention and treatment of liver diseases in clinical practice.

Objective To study the first locally identifcd A/HINI secondary cases outbreak in China. Methods Interview and field investigation were integrated to describe the whole process of transmission on each case and to illustrate the relationships between the onset of the disease and the retated factors. Results Two contact persons appearanced fever and whose throat swabs were tested positive to H1N1 viral nucleic acid. The two had a history of contact in a short distance with the initial imported case without any protective measure in the poor air ventilation. The patients clinical situation was slight. The incubation was between 37 hours and 57 hours. No other new case was found after intervention as isolation and antisepsis were taken. Conclusion This event was proved to be an outbreak of local A/H1N1 secondary cases caused by the imported case. The main mode of transmission was personal contact in a short distance without protection, through air and droplet. The locus with poor air ventilation was high risk place. Contact persons should be observed seven days and tested continuously.Infectivity and pathogenicity of the A/H1N1 virus were limited and appeared weakened by generations. Patient's condition was related with persistence and frequency of contact with the infection sources. Enhancing management of contact persons, health education, early diagnose, early treatment and early insulation were effective measures of controling and prenventing the spread A/H1N1.

OBJECTIVETo timely summarize past experience and to provide more pertinent reference for control and prevention in A/H1N1 cases in influenza season.
METHODSDuring May 25 to 31, 2009, 2 secondary community cases caused by a influenza A/H1N1 imported case. In the close contacts of 3 A/H1N1 cases, 14 had some aspirator symptoms onset, such as fever (> or = 37.5 degrees C), cough, sore throat and etc. Laboratory tests excluded the infection of A/H1N1 influenza. For throat swab test for the 14 cases, 7 were tested for seasonal influenza virus. A face-to-face or telephone interview was conducted by CDC staff to collect information of 62 close contacts.
RESULTSOf 14 fever cases, there was no significant by differences by age[15-age group: 19.2% (5/26), over 25-age group: 25.0% (9/36); chi(2) = 0.287, P = 0.592]; by sex group [24.0% (6/25) for male and 21.6% (8/37) for female; chi(2) = 0.048, P = 0.826], by working units [dressing and design, photograph, saleroom and others, consumer group: 42.1% (8/19), 27.3% (3/11), 12.5% (2/16) and 6.3% (1/16); chi(2) = 7.653, P = 0.054], by dormitory style [dormitory style = 33.3% (4/12), non-dormitory style = 29.4% (10/34); chi(2) = 0.699, P = 0.403]. All the cases had fever (37.5 - 37.9 degrees C), no case had diarrhea. One in 3 A/H1N1 cases had diarrhea. All the 14 cases were negative result for A/H1N1 RNA. Six from 7 cases were positive for seasonal influenza test.
CONCLUSIONThis was a seasonal influenza outbreak happened in the close contacts of first confirmed A/H1N1 cases in community in mainland China. It showed that we should exclude the seasonal influenza in the investigation of A/H1N1 cases in the seasonal influenza period in some time. It is necessary to take effective measure to strengthen the control and prevention of seasonal influenza.
