ABSTRACT
Fibrosis is a repair response initiated by tissues and organs after injury, and is a self-protection mechanism of the body. It has been found that endothelium-to-interstitial transdifferentiation (EndMT) is involved in the physiological and pathological processes of various organ fibrosis, which has become a focus of the research on fibrotic diseases. In recent years, the study has found that EndMT plays an important role in many pathological processes in cardiovascular system, lungs, kidneys, liver, pancreas fibrosis, and so on. This article summarizes EndMT regulatory mechanism and its role in each organ fibrosis, as well as the related treatment progress of EndMT targets, so as to provide new targets for prevention and control of organ fibrosis.
ABSTRACT
Along with increasing degree of population aging globally， senility， good health and long life have become the focus of the world. Guided by Qiluo doctrine， an essence， Qi and spirit theory is proposed as below， essence is the origin of life， Qi is the impetus of life and spirit is the embodiment of life. Based on holistic view of kidney deficiency involving the five internal organs and injuries of the five internal organs definitely affecting the kidney， a mechanism of aging is proposed as below， deficiency of kidney essence is the foundation of aging， deficiency of promordial Qi is the key of aging and physical and spiritual loss is the manifestation of aging. It provides a theoretical guidance for anti-aging study of rejuvenating the elderly and making the strong person stronger. By virtue of the experiences in kidney-tonifying medication accumulated for more than two thousand years， Bazi Bushen capsules has been developed， which has anti-aging efficacy， including tonifying kidney， replenishing essence， coordinating Yin and Yang， supplementing primordial Qi and nourishing body and spirit. Experimental researches have demonstrated that Bazi Bushen capsules can improve overall aging and systemic aging， as well as prevent and treat aging related diseases. Preliminary clinical studies demonstrate that this capsules can enhance athletic ability and improve sexual function， and is expected to become a representative Chinese patent medicine of anti-aging. This paper addresses aging and anti-aging on the basis of Qiluo doctrine， in the hope of helping prevention and treatment of aging related diseases.
ABSTRACT
The decline of body function and senile diseases caused by aging seriously affect human health and life span， which is an important topic in the field of life science. Bazi Bushen capsules is a representative Chinese patent medicine for tonifying essence， invigorating Qi and anti-aging， guided by Qiluo doctrine， and essence， Qi and spirit theory. Previous pharmacological and clinical studies have confirmed that this preparation has the comprehensive advantages of anti-aging， and prevention and treatment of aging-related diseases. Among them， pharmacological studies showed that Bazi Bushen capsules had the effect of improving the appearance status of mice， improving the level of sex hormones， inhibiting the formation of atherosclerosis， improving cardiac function， improving learning and memory cognitive ability， improving neurological function， improving osteoporosis and muscle function， improving sperm count and quality. The mechanism was related to the up-regulation of the recombinant sirtuin （SIRT6） level， down-regulation of the levels of aging-related proteins p53 and p16， up-regulation of telomerase reverse transcriptase level， and alleviation of inflammation and oxidative response. Clinical studies have proved that it can improve the symptoms of patients with kidney essence deficiency， improve exercise ability， and improve the sexual function of impotence patients. Anti-aging research of Bazi Bushen capsules based on Qiluo doctrine fully embodies the new mode of academic innovation and transformation of traditional Chinese medicine （TCM） with the combination of "theory-new drug-experiment-clinic"， which has made a demonstration for the anti-aging research of TCM.
ABSTRACT
Based on the syndrome and treatment system of collateral disease， and inheriting the development of the bloodline theory of traditional Chinese medicine （TCM）， academician WU Yi-ling systematically constructed the vessel-collateral theory of TCM and proposed that its core theory was the theory of Yingwei， that is， "Ying in the vein， and Wei outside the vein" （Huangdi Neijing·Lingshu·Yingwei Shenghui）， "obstructing of Yingwei， congelation of blood" （Treatise on Febrile Diseases· Pulse Differentiation Method）， "pathogen transferring through blood vessels， obstructed by blocking" （Jinkui Yaolue·Zangfu Jingluo Xianhou Bingmaizheng First）， and "damage of the heart， adjust its Yingwei". Based on the consistency of vessel-collateral as the channel of blood circulation in TCM with the blood vessels in western medicine， and guided by the Yingwei theory of vessel-collateral theory， the diagnostic criteria of syndrome differentiation of disease of vessel-collateral and vascular system represented by coronary heart disease， arrhythmia， heart failure and others was established to guide the prevention and treatment of vascular diseases. Based on the above analysis， guided by the Yingwei theory of vessel-collateral theory， and on the basis of related researches of vessel-collateral and vascular system， this paper discussed the etiology and pathogenesis of chronic coronary syndrome （CCS） in TCM. Taking useful collateral with unblocking as the treatment principle， the representative Tongluo prescription （Tongxinluo） was constructed， the research progress of Tongxinluo from various aspects such as animal experiment research， pharmacological research and clinical evidence-based research was summarized， a comprehensive system from etiology， pathogenesis， syndrome differentiation to treatment was formed， in order to provide new ideas for the clinical treatment of CCS.
ABSTRACT
Airway mucus is an important part of the defense barrier function of the airway. Abnormal secretion of airway mucus is closely related to recurrent attacks， delay or aggravation of respiratory infectious or infectious diseases such as chronic obstructive pulmonary disease （COPD）， community-acquired pneumonia， and coronavirus disease 2019 （COVID-19）. Lianhua Qingke tablets， an innovative traditional Chinese medicine （TCM） developed under the guidance of the theory of collateral disease of TCM， has the function of reducing phlegm and relieving cough， which can reduce the generation and viscosity of sputum and promote sputum excretion. Clinical studies have shown that it can significantly improve the symptoms of expectoration and cough in patients with acute bronchitis or COVID-19， confirming its scientific connotation and clinical value of reducing phlegm and relieving cough to improve ventilation and exchanging function.
ABSTRACT
Objective:Guided by nutrient-defense stages in the vessel-collateral theory， the modern medical cases of unstable angina pectoris（UAP） were systematically collated and analyzed to explore the rules of syndrome and treatment of UAP and the molecular mechanism of core Chinese herbal combination in the treatment of UAP based on network pharmacology. Method:All medical cases with UAP treated by Chinese medicinal compounds were retrieved from PubMed，China National Knowledge Infrastructure （CNKI），Wanfang Data， VIP， and SinoMed published between database inception and November 2020. The syndromes of medical cases were determined based on the nutrient-defense stages of the vessel-collateral theory. Rules of syndrome and treatment of UAP were investigated by data mining methods， such as frequency statistics， cluster analysis， and enhanced FP-Growth algorithm. The molecular mechanism of core Chinese herbal combination in the treatment of UAP was analyzed by network pharmacology. Result:The first four syndromes of UAP with high frequencies were deficiency and stagnation of collateral Qi， blood stasis obstructing collaterals， depression and stagnation of collateral Qi， and turbid phlegm obstructing collaterals. The Chinese herbal medicines with high frequencies included Salviae Miltiorrhizae Radix et Rhizoma， Glycyrrhizae Radix et Rhizoma， Chuanxiong Rhizoma， and Astragali Radix， which were effective in resolving stasis， dredging collaterals， replenishing Qi， consolidating defensive Qi， regulating Qi， relieving depression， and dispelling phlegm. The association analysis indicated that the core Chinese herbal combination in the treatment of UAP was Salviae Miltiorrhizae Radix Chuanxiong Rhizoma-Astragali Radix. Four Chinese herbal combinations were obtained by cluster analysis. As revealed by network pharmacology， the key components of Salviae Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma-Astragali Radix in the treatment of UAP included quercetin， luteolin， and tanshinone Ⅱ<sub>A</sub>， and the key targets included serine/threonine-protein kinase 1 （Akt1）， mitogen-activated protein kinase 1 （MAPK1）， Jun， interleukin （IL）-6， and MAPK8. Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis showed that phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt） signaling pathway might serve as the main pathway for its therapeutic efficacy. Conclusion:The basic pathogenesis of UAP is deficiency/depression and stagnation of collateral qi and turbid phlegm obstructing collaterals. The treatment should follow the principles of replenishing Qi， resolving stasis， and dredging collaterals， assisted with regulating Qi and resolving phlegm. The therapeutic efficacy of Salviae Miltiorrhizae Radix-Chuanxiong Rhizoma-Astragali Radix was achieved via multi-component， multi-target， and multi-pathway. This study is expected to inspire future UAP-related studies at the molecular level based on vessel-collateral theory.
ABSTRACT
Interventional or thrombolytic therapy for acute myocardial infarction （AMI） has the effect of opening occluded coronary arteries. However， due to no myocardial regurgitation， ischemia/reperfusion injury and microvascular structure and function destruction， leading to myocardial fibrosis following AMI， ventricular remodeling， and even cardiac failure may occur. Collaterals doctrine is used to guide the investigation into traditional Chinese medicine pathogenesis and clinical treatment of myocardial fibrosis following AMI. Consequently， it proposes the pathogenesis characteristic of "Qi deficiency and blood stasis， collaterals obstruction" and medication principle of "dispersing and dredging"， to develop the formula of Tongxinluo. Fundamental and clinical researches have demonstrated it can effectively protect the structure and function of myocardial microvascular endothelial cells， improve no reflow and reperfusion injury， and inhibit myocardial fibrosis after AMI， which further supports scientific value of the collaterals doctrine.
ABSTRACT
Metabolic syndrome (MS) is a group of syndromes caused by the disorder of metabolism of various substances in the body. The main clinical manifestations are dyslipidemia, central obesity, hypertension, abnormal glucose tolerance and insulin resistance. With the changes of diet structure and habits, the incidence rate of MS is increasing, and the patients are younger. It is an important factor in many diseases, such as diabetes, atherosclerosis, coronary heart disease, hyperlipidemia, cirrhosis and some cancers. MS has seriously affected people's lives and health. Central obesity and insulin resistance are recognized as important pathogenic factors. At present, the pathogenesis of MS and its components has not been fully understood. The clinical manifestations of metabolic syndrome are complex and diverse. Traditional Chinese medicine (TCM) believes that the occurrence of metabolic syndrome is related to such factors as proper diet, emotional disorders, excessive escape and little movement, old age and physical deficiency. TCM scholars have studied the pathogenesis of MS in such pathological factors as phlegm and blood stasis, such visceral functions as liver, spleen and kidney, roles of Qi and blood, and emotional factors. As the basic substance of organism, Qi is closely related to the process of metabolism. The occurrence of MS is closely related to the rise and fall of Qi moving to and from the body as well as the abnormal gasification function of the transformation of Qi. Qi is derived from the five internal organs, which are respectively called Heart Qi, liver Qi, spleen Qi, lung Qi and kidney Qi. The "Qi of the five internal organs" is involved in the whole process of the generation, transportation and excretion of the essence of the body. Based on the "Qi of five internal organs", this paper discusses the pathogenesis of MS with phlegm, blood stasis and water drink as pathological factors.
ABSTRACT
This paper uses the Luobing theory to guide the diagnosis and treatment of coronavirus disease-2019 (COVID-19), and states that lung collateral includes Qi collateral and blood collateral, and is the basis for playing the function of lung of dominating Qi, controlling breathing and connecting all vessels. The concept of Qi channel is different from that of Qi collateral, but its function is closely related to lung collateral. COVID-19 belongs to "pestilence" in traditional Chinese medicine. The epidemic pathogenic factor enters from mouth and nose and then causes the disease. The early characteristics of this disease include the invasion of the lung by the epidemic pathogenic factor, the obstruction of Qi channels, the prevailing of the evil and the retreat of the good, and the deficiency and stagnation of Qi collateral. Generation of toxic heat from inside, obstruction of Qi channels and dysfunction of "breathing and blood transfer" are the key links to the development and aggravation of this disease. Qi disease involves blood, blood wound intrudes into collateral, and blood consumption and hemorrhage are the late outcome of this disease. Based on the experience of doctors of all dynasties in the treatment and medication of pestilence, the treatment principle of active intervention in the early and middle stage is proposed, including focusing on pathogenesis and expelling of toxin, drug use before syndrome onset and active intervention, and the whole regulation and multi-target treatment. Lianhua Qingwen developed under the guidance of Luobing theory can inhibit the activity of novel coronavirus in vitro, relieve clinical symptoms (such as fever, cough, weakness, shortness of breath and so on) and reduce the rate of disease progression to severity. Lianhua Qingke can diffuse the lung, clear the lung heat, relieve cough and reduce sputum. It can be used to relieve the symptoms of cough and sputum in patients with COVID-19, which proves the important scientific value of Luobing theory and collateral-dredging drugs in epidemic prevention and control.

Method:A randomized controlled method was used in this clinical study. The subjects were confirmed COVID-19 patients over 18 years old with cough symptoms，and the diagnosis is based on Diagnosis and Treatment Protocol for COVID-19 （Trial Version 6）. The subjects were randomized to usual treatment （control group） or in combination with LH granule （1 bag，thrice daily） for 14 days. The primary endpoint was the rate of cough recovery. Result:57 subjects were included in this study， including 25 in the control group and 32 in the observation group. The recovery rate of cough in observation group was 90.6%（29/32）， which was significantly higher than 64.0%（16/25）in the control group （P<0.05）. The effective time of cough treatment was significantly earlier than that of the control group （P<0.05）， the median time to cough recovery was markedly shorter in treatment group （P<0.05）. The recovery rate of expectoration in observation group was 94.7% （18/19）， which was significantly higher than 57.1%（8/14）in the control group （P<0.05）. The effective time of expectoration treatment was significantly earlier than that of the control group （P<0.05）， and the median time to expectoration recovery was markedly shorter in treatment group （P<0.05）. The improvement rate of CT in the observation group was 96.9% （31/32）， which was significantly higher than 72% （18/25） in the control group （P<0.05）. After treatment， the oxygenation index of the two groups increased in varying degrees， and the increase rate of the observation group was significantly higher than that of the control group （P<0.05）. There was no significant difference in the recovery rate of fever， fatigue， dry pharynx and sore throat between the observation group and the control group， and it showed that LH had a better improvement trend on the basis of usual treatment. Conclusion:On the basis of routine treatment，LH can significantly improve the symptoms of cough and expectoration of COVID-19 patients， shorten the duration of cough and expectoration symptoms， reduce lung pathological damage， improve respiratory function， and improve the symptoms of fever， fatigue， dry pharynx and sore throat.
ABSTRACT
Related records about discipline of diagnosis and treatment of exogenous febrile diseases by traditional Chinese medicine (TCM) were reviewed to summarize TCM knowledge about etiology, pathogenesis, progress and treatment of infectious epidemic diseases among exogenous febrile diseases. In consideration of onset time and major clinical manifestations of novel coronavirus pneumonia (NCP), this disease is considered as within the scope of pestilence in TCM, it is located in the lung, with etiology being poison of winter-warm syndrome, the viruses enter body via mouth and nose, and invade pulmonary collaterals. Based on the syndrome characteristics proposed in diagnosis and treatment schemes of various regions as well as the researches on medication rules, the present study points out the core pathogenesis of NCP is epidemic toxin invading the lung, pathogenic heat obstructing the lung and toxic heat blocking the lung. It also analyzes theoretical formula features of TCM Lianhua Qingwen and related clinical and experimental research results, in order to prove the clinical value of this drug in the outbreak of NCP.
ABSTRACT
The blood-vein theory is inherited and developed. Combined with the related theory features of Qi and blood of traditional Chinese medicine(TCM), the progress results in two national 973 plan projects undertaken are learned from, the vessel-collateral theory guiding the prevention and treatment of vascular lesions is systematically built, the academic development of TCM collateral disease discipline is pushed from "treatment of symptoms of collateral disease" to study on "vessel-collateral theory", a new stage in the history. The pathogenesis, basic pathogenesis, clinical syndrome and syndrome differentiation therapy of vessel-collateral lesions are systematically studied, Yingwei theory, the core content of vessel-collateral theory, is proposed, the syndrome differential diagnosis standard of "vessel-collateral-vascular system disease" is established, and the blood-vessel theory of TCM is improved. The development of Yingwei theory of vessel-collateral theory is deepened. The theory of Yingwei sympathia and Yingwei's "opening by collaterals, intersecting and generating" are proposed to guide the study on prevention and control of vascular lesions. With tertiary collaterals-microvessel as a breakthrough point of research, four types of microscopic pathological features of microvessels are proposed. It is confirmed that dredging collaterals and protecting tertiary collaterals-microvessel is the common key mechanism for the treatment of major diseases of heart, brain and kidney(sugar). It protects microvessels, improves blood flow perfusion, protects tissue cells, and improves the viscera function. Dredging collaterals and protecting microvascular endothelial cells is the core mechanism of treating tertiary collaterals-microvessel lesions. It is proposed that protection of microvascular endothelial cells is a new strategy to solve the problem of microvascular lesions. After more than ten years, four studies of evidence-based medicine have been completed to solve the clinical problem of acute myocardial infarction without reflow. New drugs are provided to the international medical problem of cardiac insufficiency with premature ventricular contraction. The gap of fast and slow treatment, integration and rhythm adjustment of sinus bradycardia with premature ventricular contraction is filled. The clinical treatment effect of chronic heart failure is significantly improved, a major breakthrough in the treatment of microvascular lesions by TCM is achieved, and it is fully recognized and highly evaluated by the medical profession at home and abroad. It promotes the specialized subject platform construction and society development under the guidance of Yingwei theory of vessel-collateral theory, as well as the clinical application of syndrome differentiation diagnosis and treatment method and drugs of vessel-collateral lesions, and has significant social and economic benefits.
ABSTRACT
Meridians include (Qi) channels and blood (vessels). In Duyi Suibi, ZHOU Xue-hai of qing Dynasty named the terminal of Qi channel as"fine collateral of Qi" and the terminal of blood vessel as"fine collateral of blood". Qi channels of the heart cover extensive regulating mechanisms including cardiac pacing and conducting system. Blood vessels of the heart cover circulation system of coronary artery. Cardiac Qi channels and blood vessels are coordinated mutually, and Ying and Wei run together, to jointly maintain normal functions of the heart. Abnormal Yingwei caused by various pathogenic factors leads to occurrence of arrhythmia. Based on the Yingwei theory of vessel-collateral theory, this paper puts forward treatment based on syndrome differentiation of arrhythmia guided by therapeutic principle of"regulating Yingwei in case of heart damage" (Nanjing·14thNan) as well as addresses both symptoms and root causes by prescriptions for regulating Wei, Qi, Ying and blood through sufficiently considering modern pathogenic factors and pathogenic characteristics, in order to provide beneficial reference for clinical diagnosis and treatment.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the protective effects of Tongxinluo (TXL) on apoptosis of rat cardiac microvascular endothelial cells (RCMECs) resulting from homocysteine (Hcy) induced endoplasmic reticulum stress (ERS), and to determine the signaling pathway behind its protection.</p><p><b>METHODS</b>Primary cultured RCMECs were isolated from neonatal rats using tissue explant method. The morphology of RCMECs was observed using inverted microscope, identified and differentiated by CD31 immunofluorescence method. Selected were well growing 2nd-4th generations of RCMECs. The optimal action time was determined by detecting the expression of glucose regulated protein 78 (GRP78) using immunofluorescence method. In the next experiment RCMECs were divided into 5 groups, i.e., the blank control group, the Hcy induced group (Hcy 10 mmol/L, 10 h), the Hcy + TXL group (Hcy 10 mmol/L + TXL 400 µg/mL), the Hcy +LY294002 group (Hcy 10 mmol/L + LY294002 5 µmol/L, LY294002 as the inhibitor of PI3K), the Hcy + LY294002 + TXL group (Hcy 10 mmol/L + LY294002 5 µmol/L + TXL 400 µg/mL). The apoptosis rate of RCMECs was detected by flow cytometry. mRNA and protein expressions of GRP78, C/ EBP homologous protein (CHOP), and cysteinyl aspartate specific proteinase-12 (caspase12) were detected by real-time reverse transcription PCR (RT-PCR) and Western blot respectively. Expression levels of phosphorylation of phosphatidylinositol 3-kinase (P-PI3K), total phosphatidylinositol 3-kinase (T- P13K) , phosphorylation of kinase B (P-Akt) , and total kinase B (T-Akt) were detected by Western blot.</p><p><b>RESULTS</b>Ten hours Hcy action time was determined. Compared with the blank control group, the apoptosis rate was increased (22.77%), mRNA and protein expressions of GRP78, CHOP, and Caspase-12 were increased, protein expressions of P-PI3K and P-Akt,ratios of P-PI3K/T-PI3K and P-Akt/T-Akt were decreased in the Hcy induced group (P < 0.05, P < 0.01). Compared with the Hcy induced group, the apoptosis rate was decreased (10.17%), mRNA and protein expressions of GRP78, CHOP, and Caspase-12 were decreased, and expression levels of P-PI3K, P-Akt, P-PI3K/T-PI3K, and P-Akt/T-Akt were increased in the Hcy + TXL group (P < 0.05, P < 0.01). Compared with the Hcy + TXL group, the apoptosis rate was increased (17.9%), mRNA and protein expressions of GRP78, CHOP, and Caspase-12 were increased, expression levels of P-PI3K and P-Akt, ratios of P-PI3K/T-PI3K and P-Akt/T-Akt were decreased in the Hcy + TXL + LY294002 group (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>TXL could inhibit the apoptosis of RCMECs resulting from Hcy-induced ERS and its mechanism might be associated with activating PI3K/Akt signaling pathway.</p>

<p><b>BACKGROUND</b>Premature ventricular contraction (PVC) is one of the most common kinds of arrhythmias for which the treatment falls into dilemma. Previous clinical application showed that the traditional Chinese Medicine Shensongyangxin (SSYX) capsule is efficacious for the treatment of PVCs. This randomized clinical trial aimed to further evaluate the efficacy and safety of SSYX capsule on treating PVC.</p><p><b>METHODS</b>The subjects who had frequent PVCs with or without organic heart disease and normal cardiac function were enrolled in the study. The primary endpoint was the change of PVC numbers after eight-week medication with SSYX capsule. The secondary endpoints included change of clinical symptoms related to PVCs and the safety evaluation of SSYX capsule. Totally 188 PVC patients were randomly enrolled in the non-organic heart disease PVCs trial and orally took either SSYX capsules or analogues (three times per day, 4 capsules one time). A total of 671 PVCs patients were randomly enrolled in the organic heart disease PVCs trial, and orally took either SSYX capsules (three times per day, 4 capsules one time) or mexiletine tablet (three times per day, 150 mg one time). The PVCs were monitored and calculated with 24-hour Holter electrocardiogram. Routine blood, liver and kidney function were tested before and after medication with SSYX capsule.</p><p><b>RESULTS</b>SSYX capsules significantly decreased the PVCs numbers and alleviated the related symptoms in patients with or without organic heart disease. In non-organic heart disease group, SSYX capsules and the placebos decreased the PVCs from 12,561.34 ± 9,777.93 to 4,806.87 ± 6,507.17, and 12,605.69 ± 8,736.34 to 10,364.94 ± 9,903.41, respectively. The total effective rate was 74.2% and 28.9% in SSYX and placebo groups (P < 0.001). In organic heart disease group, SSYX capsule and mexiletine decreased the PVCs from 8,641.01 ± 8,923.57 to 3,853.68 ± 7,096.42, 8,621.61 ± 8,367.74 to 5,648.29 ± 8,667.38, respectively. The total effective rate was 65.8% and 50.7% in SSYX and mexiletine groups (P < 0.001). In addition, SSYX capsule significantly alleviated PVCs-related symptoms such as palpitations, chest tightness, insomnia, fatigue, and night sweats. No adverse cardiac events were observed except some slight gastrointestinal side effects during the study.</p><p><b>CONCLUSIONS</b>Compared with placebo or mexiletine, SSYX capsules have significant therapeutic efficacy in reducing PVCs numbers and alleviate PVCs-related symptoms.</p>

<p><b>BACKGROUND</b>The 2009 influenza A (H1N1) virus infection is associated with the high risk of severe complications and is spreading more rapidly throughout the world than other reported seasonal influenzas. This study aimed to evaluate the efficacy and safety of the nature herbal medicine Lianhuaqingwen capsule (LHC) in patients infected with influenza A (H1N1) virus.</p><p><b>METHODS</b>A total of 244 patients aged 16 - 65 years confirmed with influenza A (H1N1) virus infection by the real time RT-PCR were randomized to one of two treatment groups of 122 patients each. Each group assigned to receive either LHC or Oseltamivir for five days and observation for seven days. The patients were enrolled within 36 hours of illness onset if they had an axillary temperature of ≥ 37.4°C and with at least one of the following symptoms: nasal obstruction, runny nose, cough, sore throat, fatigue, headache, myalgia, chills and sweating. The primary end point was the duration of illness.</p><p><b>RESULTS</b>Of 244 patients, 240 (98.36%) patients with a median age 21 years completed the study between October 24, 2009 and November 23, 2009. There were no significant overall differences between LHC treated and Oseltamivir treated patients in the median duration of illness (LHC 69 hours vs. Oseltamivir 85 hours P > 0.05) or the median duration of viral shedding (LHC 103 hours vs. Oseltamivir 96 hours, P > 0.05). However, it was worthwhile to note that LHC significantly reduced the severity of illness and the duration of symptoms including fever, cough, sore throat, and fatigue (P < 0.05). Both study medications were well tolerated. No drug related serious adverse events occurred during the study.</p><p><b>CONCLUSIONS</b>Compared with Oseltamivir, LHC achieved a similar therapeutic effectiveness reduction of the duration of illness and duration of viral shedding. Therefore, LHC might be an alternative therapeutic measure for influenza A (H1N1) virus infections.</p>
