This study aims to obtain higher-level evidence by overviewing the Meta-analysis of Lianhua Qingwen preparations in the treatment of viral diseases including influenza, coronavirus disease 2019(COVID-19), and hand, foot and mouth disease(HFMD). CNKI, Wanfang, VIP, China Clinical Trial Registry(ChiCTR), PubMed, EMbase, Web of Science, and Cochrane Library were searched for the Meta-analysis about the treatment of viral diseases with Lianhua Qingwen preparations from the database establishment to April 1, 2022. After literature screening and data extraction, AMSTAR2 and the grading of recommendations assessment, development and evaluations(GRADE) system were used to assess the methodological quality and evidence quality, respectively, and then the efficacy and safety outcomes of Lianhua Qingwen preparations in the treatment of viral diseases were summarized. Thirteen Meta-analysis were finally included, three of which were rated as low grade by AMSTAR2 and ten as very low grade. A total of 75 outcome indicators were obtained, involving influenza, COVID-19, and HFMD. According to the GRADE scoring results, the 75 outcome indicators included 5(6.7%) high-level indicators, 18(24.0%) mediate-level indicators, 25(33.3%) low-level evidence indicators, and 27(36.0%) very low-level indicators.(1)In the treatment of influenza, Lianhua Qingwen preparations exhibited better clinical efficacy than other Chinese patent medicines and Ribavirin and had similar clinical efficacy compared with Oseltamivir. Lianhua Qingwen preparations were superior to other Chinese patent medicines, Oseltamivir, and Ribavirin in alleviating clinical symptoms. They showed no significant differences from Oseltamivir or conventional anti-influenza treatment in terms of the time to and rate of negative result of viral nucleic acid test.(2)In the treatment of COVID-19, Lianhua Qingwen preparation alone or combined with conventional treatment was superior to conventional treatment in terms of total effective rate, main symptom subsidence rate and time, fever clearance rate, duration of fever, time to fever clearance, cough subsidence rate, time to cough subsidence, fatigue subsidence rate, time to fatigue subsidence, myalgia subsidence rate, expectoration subsidence rate, chest tightness subsidence rate, etc. Lianhua Qingwen preparations no difference from conventional treatment in terms of subsiding sore throat, nausea, diarrhea, loss of appetite, headache, and dyspnea. In terms of chest CT improvement rate, rate of progression to severe case, cure time, and hospitalization time, Lianhua Qingwen alone or in combination with conventional treatment was superior to conventional treatment.(3)In the treatment of HFMD, Lianhua Qingwen Granules was superior to conventional treatment in terms of total effective rate, average fever clearance time, time to herpes subsidence, and time to negative result of viral nucleic acid test.(4)In terms of safety, Lianhua Qingwen preparations led to low incidence of adverse reactions, all of which were mild and disappeared after drug withdrawal. The available evidence suggests that in the treatment of influenza, COVID-19, and HFMD, Lianhua Qingwen preparations can relieve the clinical symptoms, shorten the hospitalization time, and improve the chest CT. They have therapeutic effect and good safety in the treatment of viral diseases. However, due to the low quality of available studies, more high-quality clinical trials are needed to support the above conclusions.

This study aimed to evaluate the cost-effectiveness of Chaiyin Granules compared with Oseltamivir Phosphate Capsules in the treatment of influenza(exogenous wind-heat syndrome). Based on a randomized, double-blind, positive drug parallel control clinical trial, this study evaluated the pharmacoeconomics of Chaiyin Granules with cost-effectiveness analysis method. A total of 116 patients with influenza from eight hospitals(grade Ⅱ level A above) in 6 cities were selected in this study, including 78 cases in the experimental group with Chaiyin Granules and Oseltamivir Phosphate Capsules placebo, and 38 cases in the control group with Oseltamivir Phosphate Capsules and Chaiyin Granules placebo. The total cost of this study included direct medical cost, direct non-medical cost, and indirect cost. The remission time of clinical symptoms, cure time/cure rate, antipyretic onset time/complete antipyretic time, viral nucleic acid negative rate, and traditional Chinese medicine(TCM) syndrome curative effect were selected as the effect indicators for cost-effectiveness analysis. Four-quadrant diagram was used to estimate the incremental cost-effectiveness ratio. The results showed that Chaiyin Granules were not inferior to Oseltamivir Phosphate Capsules in the remission time of clinical symptoms of influenza(3.1 d vs 2.9 d, P=0.360, non-inferiority margin was 0.5 d). Compared with Oseltamivir Phosphate Capsules, Chaiyin Granules would delay the remission time of clinic symptoms of influenza for 1 d, but could save 213.9 yuan. 1 d delay in cure time could save 149.3 yuan; 1% reduction in the cure rate could save 8.2 yuan; 1 d delay in antipyretic onset time could save 295.4 yuan; 1 d delay in complete antipyretic time could save 114.3 yuan; 1% reduction in the 5-day cure rate of TCM syndrome could save 19.2 yuan. Different from other indicators, there was no statistically significant difference between two groups in the effect of negative conversion rate of viral nucleic acid, but the cost was lower and the effect was superior, and the pharmacoeconomics was not different from that of Oseltamivir Phosphate Capsules in the field of influenza treatment.

Influenza is a global contagious disease, which causes hundreds of thousands of people deaths. And new subtype of influenza may cause pandemic influenza, and lead to more serious consequence. Drugs for anti-influenza have played very important roles in influenza treatment and prevention, especially neuraminidase inhibitors are effective on both influenza A and B which have more safety and tolerance, therefore they have been widely used for influenza treatment. However, several viral drug-resistant cases have been reported. In this paper, the clinic therapy, prevention and drug resistance of neuraminidase inhibitors, including zanamivir, oseltamivir and peramivir, and progress in the research and development in our country are presented in order to promote research and development of new drugs for influenza treatment and prevention.

OBJECTIVETo evaluate the efficacy and safety of oseltamivir phosphate as treatment for naturally acquired influenza infection.
METHODSThis study was conducted as a double-blind, randomized, placebo-controlled, multicenter trial during the influenza epidemic season from January to April 2001 at 7 centers in China. A total of 478 adults without other medical history, aged 18 to 65 years, were enrolled into the study. All subjects demonstrated febrile respiratory illness of no more than 36 hours' duration with a temperature of 37.8 degrees C or more plus at least two of the following symptoms: coryza/nasal congestion, sore throat, cough, myalgia/muscles aches and pain, fatigue, headache or chills/sweats. Individuals were randomized into either the oseltamivir phosphate or placebo group with identical-looking capsules. Either oral oseltamivir phosphate, 75 mg twice daily, or placebo was administered to the subjects for 5 days.
RESULTSA total of 451 individuals were analyzed for efficacy as the intent-to-treat population (ITT) (216 oseltamivir and 235 placebo) and 273 individuals were identified as influenza-infected through laboratory test, who were then defined as the intent-to-treat infected population (ITTI) (134 oseltamivir and 139 placebo). Four hundred and fifty nine individuals were included in the safety analysis. In the ITTI population, the cumulative alleviation proportion of oseltamivir group was significantly higher than that of the placebo group (P = 0.0466)). The median duration of illness was 91.6 h [95% confidence interval (CI) = 80.2 - 101.3 h] in the oseltamivir group and 95 h (95% CI = 84.5 - 105.3 h) in the placebo group. The median area under the curve of decreased total score was significantly higher in the oseltamivir group than in the placebo group, 1382.9 and 1236.7 score-hours, respectively (P = 0.0196). For the ITT population, similar results were observed. Adverse events (AE) were similarly reported in both the oseltamivir group and the placebo group. The main adverse events following test drug were gastrointestinal symptoms, neurological symptoms and rashes.
CONCLUSIONOseltamivir was effective and well tolerated as treatment of early naturally acquired influenza.

In the advent of an influenza virus pandemic it is likely that the administration of antiviral drugs will be an important first line of defence against the virus. The drugs currently in use are effective against seasonal influenza virus infection, and some cases have been used in the treatment of patients infected with the avian H5N1 influenza virus. However, it is becoming clear that the emergence of drug-resistant viruses will potentially be a major problem in the future efforts to control influenza virus infection. In addition, during a new pandemic, sufficient quantities of these agents will need to be distributed to many different parts of the world, possibly at short notice. In this review we provide an overview of some of the drugs that are currently available for the treatment and prevention of influenza virus infection. In addition, basic research on influenza virus is providing a much better understanding of the biology of the virus, which is offering the possibility of new anti-influenza virus drugs. We therefore also review some new antiviral strategies that are being reported in the scientific literature, which may form the basis of the next generation of antiviral strategies during a future influenza virus pandemic.

This study aims to explore the efficacy and safety of Lianhua Qingwen preparations combined with Oseltamivir in the treatment of influenza patients. PubMed, Cochrane Library, EMbase, SinoMed, CNKI, Wanfang, and VIP were searched for the randomized controlled trials(RCTs) involving the comparison between the influenza patients treated with Lianhua Qingwen preparations combined with Oseltamivir and those treated with Oseltamivir alone. Fever clearance time was taken as the primary outcome indicator. Clinical effective rate(markedly effective and effective), time to muscle pain relief, time to sore throat relief, time to cough relief, time to nasal congestion and runny nose relief, time to negative result of viral nucleic acid test, and adverse reactions were taken as the secondary outcome indicators. The data were extracted based on the outcome indicators and then combined. The Cochrane collaboration's tool for assessing risk of bias was used to evaluate the quality of a single RCT, and the grading of recommendations assessment, development and evaluations(GRADE) system to assess the quality of a single outcome indicator. RevMan 5.3 was employed to analyze data and test heterogeneity. Finally, 16 RCTs involving 1 629 patients were included for analysis. The Meta-analysis showed that Lianhua Qingwen preparations combined with Oseltamivir was superior to Oseltamivir alone in the treatment of influenza in terms of clinical effective rate(RR=1.16, 95%CI [1.12, 1.20], P<0.000 01), fever clearance time(SMD=-2.02, 95%CI [-2.62,-1.41], P<0.000 01), time to muscle pain relief(SMD=-2.50, 95%CI [-3.84,-1.16], P=0.000 2), time to sore throat relief(SMD=-1.40, 95%CI [-1.93,-0.85], P<0.000 01), time to cough relief(SMD=-1.81, 95%CI [-2.44,-1.19], P<0.000 01), time to nasal congestion and runny nose(SMD=-2.31, 95%CI [-3.61,-1.01], P=0.000 5), and time to negative result of viral nucleic acid test(SMD=-0.68, 95%CI [-1.19,-0.16], P=0.01). However, due to the low quality of the trials, the above conclusions need to be proved by more high-quality clinical studies. In addition, we still need to attach importance to the adverse reactions of the integrated application of Chinese and western medicines.

OBJECTIVEDuring the 2009 influenza A (H1N1) epidemic in China, children are the main group among people infected with influenza A (H1N1) virus, but few reports about children are available. The present study aimed to observe the clinical, laboratory features and to analyze therapeutic result.
METHODThe research subject were 93 children infected with influenza A (H1N1), 59 male and 34 female who were treated in Beijing Ditan Hospital from 15 May 2009 to 10 September 2009. The patients' data on symptoms, signs, chest X-ray, blood routine test, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), liver function, renal function, helper T lymphocyte were collected and analyzed. The patients were treated with Oseltamivir, traditional Chinese medicine and symptomatic treatment.
RESULTThe main symptoms of children infected with influenza A (H1N1) are fever (84 cases, 90.3%), cough (62 cases, 66.7%), pharyngodynia (36 cases, 38.7%) and expectoration (19 cases, 20.4%) at onset, and fever (59 cases, 63.4%), cough (52 cases, 55.9%), pharyngodynia (23 cases, 24.7%) and expectoration (9 cases, 9.7%) were the mojor symptoms and signs while the patients visited our hospital. The main signs were fervescence, pharyngeal congestion (53 cases, 57.0%), tonsilar swelling (21 cases, 22.6%), and abnormal white blood count (WBC) was found in 32 cases, abnormal ESR in 10 cases, abnormal CRP in 10 cases, abnormal CD4 T lymphocyte count in 19 cases, abnormal liver function and renal function were found in very few patients. After treatment, the febrile duration and time to virus negative in patients treated with oseltamivir alone, traditional Chinese medicine alone, combined oseltamivir and traditional Chinese medicine as well as those who were neither treated with oseltamivir nor traditional Chinese medicine were respectively 1 - 6 days (median 1 day), 3 - 13 days (median 7 days), 1 - 6 days (median 1.5 days), 4 - 11 days (median 8 days), 1 - 5 days (median 1 days), 5 - 14 days (median 8 days), 1 - 5 days (median 2 days), 4 - 13 days (median 8 days).
CONCLUSIONClinical manifestations of 93 children cases were the same as those of adults. The traditional Chinese medicine could improve symptoms of children infected with influenza A (H1N1), but other clinical therapeutic effects need further study.

The aim of this study was to describe the features of deaths associated with the 2009 pandemic influenza A (H1N1) by 26 November 2009 in Korea. We collected standardized case reports on 115 confirmed deaths through a nationwide enhanced influenza surveillance system. The median age was 61 yr (interquartile range [IQR], 0.2-97 yr) and 58 (50.4%) were females. The case fatality rate was estimated as 16 per 100,000 cases. The age-related mortality rate had a J-shaped curve. Eighty-three patients (72.2%) had at least 1 underlying medical disease. Bacterial co-infections were detected in the blood or sputum specimens from 34 patients. Of the 63 patients who were hospitalized in the intensive care unit (ICU), the median time from symptom onset to hospital admission was 2 days (IQR, 0-22 days), and the median time from hospitalization to ICU admission was 1 day (IQR, 0-17 days). Neuraminidase inhibitors were administered to 100 patients (87.0%), 36% of whom began treatment within 2 days. In conclusion, fatal cases from the 2009 influenza A (H1N1) infection in Korea are mainly aged individuals with underlying disease, and associated with pneumonia, bacterial co-infections, and multi-organ failure.
