OBJECTIVETo observe the change of cytokine interleukin IL-1 beta, IL-6, IL-10, tumor necrosis factor-alpha (TNF-alpha) occurred in acute paraquat (PQ) poisoning rats and to investigate the mechanism of acute lung injury caused by paraquat (PQ) poisoning.

METHODSAll 72 healthy adult Wistar rats were random assigned into normal control groups, paraquat high dose group (120 mg/kg), paraquat middle dose (60 mg/kg) group, paraquat low dose group (30 mg/kg). Three observing periods of time included 8, 24, 72 h and the standards of TNF-alpha, IL-1 beta, IL-6, IL-10 were determined.

RESULTSEvery index of the PQ group was significantly higher than that in the NS group at the same period of time (P<0.05 or P<0.01). In the 72 h group, the high dose group was significantly higher than the middle and low dose group (P<0.05), and there was no significantly difference between the middle and low dose group (P>0.05). For the comparison of index in the same dose group, the group of 72 h was much higher than 8 h group and 24 h group (P<0.05), and there was no difference between the 8h group and 24 h group (P>0.05).

CONCLUSIONThe cytokine may play an important role in paraquat-induced acute lung tissue injury.

We investigated brucellosis incidence trends in Kashgar,Xinjiang in 2005-2016 for further prevention and control,and analyzed the brucellosis epidemiological characteristics there,by using the descriptive epidemiology method.A total of 767 cases were reported,with an average annual incidence of 1.68/100 000,and incidence of annual report showed a relatively stable trend (Z:29.49,P＜0.001).The maximum number of reported cases was mainly concentrated from May to July.Incidence ratio of the male and female was 1.81:1.Cases were identified in each age group,the minimum age was five months,and the maximum age was 85 years old,with the median of 39.The highest proportion of reported cases was peasant.The top five average annual incidence counties (cities) were the Markit County,Yopurga County,Tashikuergan Tajik Autonomous County,Bachu County and Kashgar City.The brucellosis incidence increased year by year,especially during 2012-2016.We need further analysis for the data from increasing brucellosis outbreak and further strengthen the prevention and control of that in Kashgar area.

OBJECTIVETo compare the postoperative hemorrhage between standard uvulopalatopharyngoplasty (UPPP) and coblation assisted UPPP, and to evaluate the related risk factors and preventive measures.

METHODSFive hundreds and ninety seven patients with obstructive sleep apnea hypopnea syndrome (OSAHS) underwent UPPP and coblation assisted UPPP between January 1, 1999, and September 30, 2009 were reviewed retrospectively. Two hundred and sixty three patients with coblation assisted UPPP and 334 patients with standard UPPP were treated respectively. Single factor statistic analysis, multiple factors Logistic regress statistic analysis and Wilcoxon test method for related risk factors were applied.

RESULTSA total of 42 patients (7.0%) experienced postoperative bleeding. Among them, 24 patients with coblation assisted UPPP (9.1%) and 18 patients with UPPP (5.4%) had postoperative hemorrhage. Significant difference was not found in the degree of hemorrhage (z = 0.784, P > 0.05), hemorrhage site(χ(2) = 1.387, P > 0.05) and postoperative hemorrhage rates (χ(2) = 3.14, P > 0.05) between the two surgical techniques. Significant difference was found in the interval of hemorrhage after surgery between the two surgical techniques (χ(2) = 9.25, P < 0.01). History of hypertension, smoking, hepatic dysfunction was found to be correlated with the postoperative hemorrhage (Odd-ratio were respectively 7.326, 3.674, 2.707).

CONCLUSIONCoblation technique did not significantly increase UPPP postoperative hemorrhage.

Rabies is a zoonosis caused by rabies virus for which no effective treatment is available.The main preventive measure is vaccination with human rabies vaccine before or after rabies exposure.With progress in science and technology,the production process of human rabies vaccine has continually advanced,thereby increasing vaccine quality,and providing a safer,more effective means of rabies prevention and control through increasing human resistance to rabies.New human rabies vac-cines have made breakthroughs in basic research and clinical research.However,the problems of poor vaccine compliance and low vaccination rates must urgently be addressed.China must actively explore effective coping strategies,accelerate the upda-ting of existing immunization procedures,effectively increase the rabies vaccination rate,and achieve the goal of eliminating ra-bies by 2030 as soon as possible.

The vaccination status of influenza, pneumococcus and other non-immunization planning vaccines at home and abroad and the related researches on effectively improving the vaccination rate were comprehensively reviewed. We found that the vaccination rates of influenza, pneumococci and other vaccines in some countries are at a high level, which is due to the fact that the country has included them in the immunization plan or given government financial support. In addition, a series of multimodal strategies integrating patient education, medical training, electronic information technology and compulsory vaccination have also effectively improved the vaccination coverage. At present, the vaccination rates of influenza, pneumococcus and other vaccines in China are generally low. We should actively learn from the advanced strategies and experience of various countries and take effective measures to improve the vaccination rate, so as to protect people's life and health better.

A comprehensive review of the research of the effectiveness of influenza vaccine and 23 valent pneumococcal polysaccharide vaccine (PPV23) in patients with chronic obstructive pulmonary disease (COPD) both at home and abroad in recent years showed that influenza vaccine and PPV23 immunization can significantly reduce the risk for influenza and pneumonia in COPD patients, and reduce the acute exacerbation of disease and related hospitalization. In particular, the influenza vaccination can also reduce the risk for ischemic heart disease, acute coronary syndrome, ventricular arrhythmia, lung cancer, dementia and death in the patients, and the immunization of both vaccines has a more significant protective effect. It is recommended by authoritative guidelines both at home and abroad that COPD patients can receive influenza vaccine and PPV23. At present, the coverage of domestic influenza and pneumococcal vaccines are low, and there are less studies in the applications of both vaccines in patients with COPD. Effective measures should be taken to strengthen the health education and increase the vaccination coverage. Additionally, the clinical research of influenza vaccine and PPV23 for COPD patients, especially the analysis on clinical benefit of immunization of both vaccines, should be further strengthened to effectively improve the survival and prognosis of COPD patients.

This article reviews the relevant studies on the efficacy and safety of influenza, pneumococcal and COVID-19 vaccination among tumor patients worldwide in recent years. By combing and analyzing the retrieved literature, the results show that influenza and pneumococcal vaccination can significantly reduce the morbidity and hospitalization rate of infectious diseases in tumor patients, reduce the risk of cardiovascular events and death, and significantly improve survival prognosis. COVID-19 vaccination can also protect tumor patients, especially those who have completed full dose vaccination. Authoritative guidelines and consensuses worldwide all recommend that tumor patients receive influenza, pneumococcal and COVID-19 vaccines. We should carry out relevant researches, as well as take effective measures to strengthen patient education, so that tumor patients can fully experience the health protection brought by the vaccine to this specific group.

This paper reviews the domestic and foreign studies published in 2020 on the application of influenza vaccine in populations at high risk. The importance of influenza vaccination in population at high risk has been proved by larger sample, multicentre, high-quality evidence-based studies. Influenza vaccination is the most cost-effective measure to prevent influenza. However, the coverage rate of influenza vaccine is very low in China, it is necessary to strengthen the health education to promote influenza vaccination in different populations. It is recommended to give influenza vaccination to the population in whom influenza vaccination has been proven safe and effective before influenza season. Research of the safety, efficiency and cost-effectiveness of influenza vaccine should be accelerated for the populations in whom such data are lacking or insufficient.
