RESUMEN
Chaihu Jia Longgu Muli Decoction was firstly recorded in Treatise on Cold Damage(ZHANG Zhong-jing, Eastern Han dynasty). According to this medical classic, it is originally used in the treatment of the Shaoyang and Yangming syndrome. Based on the modern pathophysiological mechanism, this study interpreted the classic provisions of Chaihu Jia Longgu Muli Decoction. Original records of "chest fullness" "annoyance" "shock" "difficult urination" "delirium" "heavy body and failing to turn over" all have profound pathophysiological basis, involving disorders in cardiovascular, respiratory, nervous, and mental systems. This formula is widely used, which can be applied to treat epilepsy, cerebral arteriosclerosis, cerebral infarction, and other cerebrovascular diseases, hypertension, arrhythmia, and other cardiovascular diseases, insomnia, constipation, anxiety, depression, cardiac neurosis and other acute and chronic diseases as well as diseases in psychosomatic medicine. The clinical indications include Bupleuri Radix-targeted syndrome such as fullness and discomfort in chest and hypochondrium, bitter taste mouth, dry throat, and dizziness, the insomnia, anxiety, depression, susceptibility to fright, upset, dreamfulness and other psychiatric symptoms, red tongue, thick and yellow tongue coating, and wiry hard and powerful pulse. This formula was found to be used in combination with other formulas, such as Gualou Xiebai Decoction, Wendan Decoction, Zhizhu Pills, Juzhijiang Decoction, Suanzaoren Decoction, and Banxia Baizhu Tianma Decoction.

BACKGROUND: Traditional Chinese medicine has been found effective for the therapy of knee osteoarthritis (KOA). This study was aimed at investigating the underlying mechanism of Bugan Rongjin decoction (BGRJ) in treating the postmenopausal KOA. RESULTS: Ovariectomized rat model of KOA and LPS-induced chondrocytes were successfully constructed for in vivo and in vitro model of postmenopausal KOA. X-ray and hematoxylin-eosin (H&E) staining showed that BGRJ alleviated pathological damage of articular cartilage in OVX rats with KOA. In addition, BGRJ inhibited inflammation and oxidative stress through decreasing the levels of serum IL-6, IL-1ß, TNF-α and NO and regulated Wnt signaling pathway by downregulating the expression of Wnt5a and ß-catenin and upregulating the expression of Sox9 and Collagen II in cartilage tissue, detected by immunohistochemistry (IHC) and western blot analysis. Furthermore, Wnt5a silencing reduced the apoptosis of LPS-induced ADTC5 cells, which was further suppressed by the combination of downregulation of Wnt5a and BGRJ. CONCLUSIONS: In summary, BGRJ alleviates inflammation and oxidative stress to treat the postmenopausal KOA through Wnt signaling pathway.

Coronavirus disease 2019(COVID-19) refers to the pneumonia caused by novel coronavirus(2019-nCoV) infection in 2019. It is highly infectious, with quick spreading and a wide range of impact. It has been broken out in many countries around the world and has become a public health emergency of international concern. Chinese medicine has a long history in treating plague, and viral disease is the clinical advantage in Chinese medicine. Under the premise that there is currently no specific drug treatment, Chinese medicine has achieved certain effects in the treatment of COVID-19, which has attracted much attention and has been upgraded to a national strategy. Regarding the treatment of COVID-19 with Chinese medicine, it is believed that in terms of the name of Chinese medicine, the modern connotation of "uniform of typhoid and febrile disease" should be re-recognized, and it is advisable to use drugs based on specific clinical prescriptions and indications. In terms of pathogenesis, the COVID-19 has the pathogenesis rules including from the mild to severe conditions, from the surface to the inside, from the excess syndrome to the deficiency syndrome. We should pay attention to the Taiyang syndrome damaged by wet disease in initial stage, Shaoyang syndrome complicated with Yangming syndrome in the middle stage, phlegm-heat obstructing lung in critical period, lung and spleen deficiency in the recovery stage. In terms of clinical treatment strategies, Dayuan Yin is recommended to induce sweat and disperse the stasis in early stage. Xiaochaihu Decoction and Maxing Shigan Decoction is used to relieve both exterior and interior symptoms in middle stage. In critical stage, Tingli Dazao Xiefei Decoction, Weijing Decoction, Xuanbai Chengqi Decoction, Xiaoxianxiong Decoction, and Sanzi Yangqin Decoction are considered to reduce phlegm and clear heat. We should pay attention to nourishing Qi and strengthening the spleen by Zhuye Shigao Decoction, Sha-shen Maidong Decoction, and Liujunzi Decoction in the later recovery period. It shall be noted that, no matter in the initial mild stage, the middle and critical stages, or in the later recovery stage, Chinese medicine plays an important role, including preventing mild to severe disease, shortening the fever time, improving cough symptoms, increasing blood oxygen saturation and reducing mortality. Many studies have shown that the classical herbal formulae can alleviate the cytokine storm, regulate the immune imbalance, and produce the potential effect of synergistic treatment for COVID-19 through multiple components, multiple targets, and multiple pathways.

Currently, coronavirus disease 2019 (COVID-19), which can lead to severe respiratory failure and death, is now a global pandemic with no specific anti-viral drugs or vaccines. However, It is worth noting that traditional Chinese medicine (TCM), especially Chinese herbal medicine (CHM), has been widely applied in mainland China since outbreak, bringing new hope for the prevention and control of COVID-19. A comprehensive literature searching was conducted in 7 electronic databases from their inception up to June 21, 2020 to evaluate the efficacy and safety of CHM for COVID-19. Eighteen randomized controlled trials (RCTs) involving 2275 patients were enrolled. Most of CHMs were originated from classical Chinese herbal formulas. Liquoric Root (Gancao, Radix Glycyrrhizae), Baical Skullcap Root (Huangqin, Radix Scutellariae Baicalensis), Pinellia Rhizome (Banxia, Rhizoma Pinelliae Tematae), Forsythia Fruit (Lianqiao, Fructus Forsythiae Suspensae), and Bitter Apricot Seed (Kuxingren, Semen Armeniacae Amarum) were most frequently used Chinese herbs. The most commonly used dosage formulation was decoction. Our meta-analyses found that comparing CHM group and conventional western medicine group, CHM group has improvements in several clinical parameters including lung CT, clinical cure rate, ranging from mild to critical cases, length of hospital stay, total score of clinical symptoms, fever reduction time, symptom score of fever, number of cough reduction cases, symptom score of cough, number of fatigue reduction cases, symptom score of fatigue, disappearing time of fatigue, TCM syndrome, viral nucleic acid testing, and inflammatory biomarkers (C-reactive protein). Besides, no severe adverse effects was identified by CHM. CHM, especially classical Chinese herbal formulas, could be used as potential candidates for COVID-19 in this battle.

BACKGROUND: Community acquired pneumonia remains a leading infectious cause of hospitalization with substantial morbidity and mortality in China. At present, the role of atypical pathogens in CAP arouses peoples' concern. Previous studies indicated that MP was the dominant pathogen of CAP, but the associated factors of MP infection were rarely reported. METHODS: We retrospectively investigated the distribution of atypical pathogens related with CAP and compared their differences among various populations. Furthermore, we accessed the associated factors of MP infection in various population. RESULTS: A total of 3,675 patients were enrolled and divided into three groups. One thousand and eighty-nine subjects (29.6%) were infected with at least one atypical pathogen. MP was the most predominant pathogen in these CAP patients. Our study found that infection rates of the atypical pathogens were significantly different among three groups. Our results also revealed, in a pediatric group, as the temperature increased, so did the infection rate of MP, while it was the opposite in adult and elderly groups. Furthermore, in preschool and school-age children, high temperature, female, PIVs, ADV, and INFB infection were independent risk factors for MP infection, INFA infection was a protection factor for MP infection. However, in adult and elderly groups, the associated factors might be different. CONCLUSIONS: The infection of atypical pathogens related with CAP is quite serious, and MP infection plays a key role in CAP. Besides, the infection rates of the atypical pathogens are different in various populations, as are the associated factors for MP infection.

Cream formula has been mostly used to treat deficiency syndrome. Currently,it has been used to recuperate the body,promote health against aging,and prevent and treat chronic disease. In modern medicine,there are only treatment concepts and methods of diseases,but lack of concepts of " deficiency syndrome" and " restoring deficiency". The concepts of " deficiency syndrome" and " restoring deficiency" could effectively supplement and improve the diagnosis and treatment scheme of some modern diseases. Refractory heart failure,dilated cardiomyopathy,ischemic cardiomyopathy,and valvular heart disease belong to the traditional category of " consumptive disease". The cream formula with the efficacy of restoring deficiency can not only alleviate symptoms and improve the quality of life,but also improve the structure and function of the heart,reduce the dosage of diuretics and the number of hospitalizations,and achieve the purpose of secondary prevention in the treatment of severe heart failure,dilated cardiomyopathy,ischemic cardiomyopathy and valvular heart disease. The cream formula for treating chronic heart failure include Shenqi Pills,Zhenwu Decoction,Yougui Pills,Wuling Powder,Linggui Zhugan Decoction,Danggui Shaoyao Powder,Lizhong Decoction,Buzhong Yiqi Decoction,Guipi Decoction,Yupingfeng Powder,Guizhi Decoction. Long-term administration of cream formula could not only resist aging,but also play an irreplaceable role in the secondary prevention of acute and critical diseases.

Chronic cough is a common clinical disease with complex etiology, which is easily misdiagnosed and mistreated. Chronic cough guideline has been developed based on the modern anatomical etiology classification, and it may improve the level of diagnosis and treatment. Common causes of chronic cough are as follows: cough variant asthma, upper airway cough syndrome, eosinophilic bronchitis, gastroesophageal reflux-related cough, post-infectious cough, etc. There is a long history and rich experience in treatment of cough in traditional Chinese medicine which is characterized by syndrome differentiation. The four elements of pathogenesis for chronic cough include wind, phlegm, fire, and deficiency. Classic formula is widely used in the treatment of chronic cough, and the focus is on prescriptions corresponding to syndromes. This article attempts to explore the thought and method of classic formulae in treatment of chronic cough based on three perspectives: differentiation of etiology, pathogenesis and formula-syndrome. Three medical cases are selected at last in order to prove its correction.

ETHNOPHARMACOLOGICAL RELEVANCE: Trichosanthis pericarpium (TP; Gualoupi, pericarps of Trichosanthes kirilowii Maxim) has been used in traditional Chinese medicine (TCM) to reduce heat, resolve phlegm, promote Qi, and clear chest congestion. It is also an essential herbal ingredient in the "Gualou Xiebai" formula first recorded by Zhang Zhongjing (from the Eastern Han Dynasty) in the famous TCM classic "Jin-Guì-Yào-Lüe" for treating chest impediments. According to its traditional description, Gualou Xiebai is indicated for symptoms of chest impediments, which correspond to coronary heart diseases (CHD). AIM OF THE STUDY: This study aimed to identify the antithrombotic compounds in Gualoupi for the treatment of CHD. MATERIALS AND METHODS: A CHD rat model was established with a combination of high-fat diet and isoproterenol hydrochloride (ISO) administration via subcutaneous multi-point injection in the back of the neck. This model was used to evaluate the antithrombotic effect of two mainstream cultivars of TP ("HaiShi GuaLou" and "WanLou") by analyzing the main components and their effects. Network pharmacology, molecular docking-based studies, and a zebrafish (Danio rerio) thrombosis model induced by phenylhydrazine was used to validate the antithrombosis components of TP. RESULTS: TP significantly reduced the body weight of the CHD rats, improved myocardial ischemia, and reduced collagen deposition and fibrosis around the infarcted tissue. It reduced thrombosis in a dose-dependent manner and significantly reduced inflammation and oxidative stress damage. Cynaroside, isoquercitrin, rutin, citrulline, and arginine were identified as candidate active TP compounds with antithrombotic effects. The key potential targets of TP in thrombosis treatment were initially identified by molecular docking-based analysis, which showed that the candidate active compounds have a strong binding affinity to the potential targets (protein kinase C alpha type [PKCα], protein kinase C beta type [PKCß], von Willebrand factor [vWF], and prostaglandin-endoperoxide synthase 1 [PTGS1], fibrinogen alpha [Fga], fibrinogen beta [Fgb], fibrinogen gamma [Fgg], coagulation factor II [F2], and coagulation factor VII [F7]). In addition, the candidate active compounds reduced thrombosis, improved oxidative stress damage, and down-regulated the expression of thrombosis-related genes (PKCα, PKCß, vWF, PTGS1, Fga, Fgb, Fgg, F2, and F7) in the zebrafish model. CONCLUSION: Cynaroside, isoquercitrin, rutin, citrulline, and arginine were identified as the active antithrombotic compounds of TP used to treat CHD. Mechanistically, the active compounds were found to be involved in oxidative stress injury, platelet activation pathway, and complement and coagulation cascade pathways.

OBJECTIVE: To study and analyze the etiology and pathogenesis, diagnosis and prescription for cases of diabetic nephropathy (DN) treated by Professor Zhongying Zhou (Prof. Zhou) with the help of dada mining technique, so as to inherit his clinical experience and academic thoughts. METHODS: After pretreatment of the medical record information, statistical software SPSS 13.0 was used to analyze and process the standardized data using the descriptive analysis, cluster analysis and association rules. RESULTS: Ninety-four entries derived from Traditional Chinese Medicine (TCM) four-diagnostic information were selected. Through data mining, the highest frequency was yellow-thin-greasy tongue coating, followed by dark tongue, and then by thready-slippery pulse. The main self-conscious symptoms were limb numbness, dry mouth, frequent micturition, etc. With respect to pathogenesis, the etiology related to kidney reached 73.46%. The frequency of pathological factors for deficiency, blood stasis, heat, dampness, phlegm and dryness were 137.65%, 80.25%, 78.40% , 48.77%, 21.60%, and 14.20% respectively. A total of 236 kinds of herbs were used 2913 person times, averaging 17.98 herbs per prescription. CONCLUSION: The pathological location of DN is in the kidney. The pathogenesis of the disease is deficiency in origin and excess in superficiality, the former of which include deficiency of the liver and kidney, and deficiency of both Qi and Yin. The main pathological factors are blood stasis, heat, dampness, phlegm, and dryness; and they act upon each other to form the complex pathogenesis in terms of blood stasis-heat, dampness-heat, phlegm-heat, and dryness-heat. All the above factors are always crucial in the aggravation of DN throughout the whole course of its pathological evolution.

BACKGROUND: Preserved ratio impaired spirometry (PRISm) findings are a heterogeneous condition characterized by a normal FEV1 to FVC ratio with underlying impairment of pulmonary function. Data relating to the association of baseline and trajectories of PRISm findings with diverse cardiovascular outcomes are sparse. RESEARCH QUESTION: How do baseline and trajectories of PRISm findings impact subsequent cardiovascular events? STUDY DESIGN AND METHODS: In the UK Biobank cohort study, we included participants free of cardiovascular disease (CVD) with spirometry (FEV1 and FVC values) at baseline (2006-2010). Participants with baseline spirometry and follow-up spirometry (2014-2020) were included in the lung function trajectory analysis. Cox proportional hazards multivariate regression was performed to evaluate the outcomes of major adverse cardiovascular events (MACEs), incident myocardial infarction (MI), stroke, heart failure (HF), and CVD mortality in association with lung function. RESULTS: For baseline analysis (329,954 participants), the multivariate adjusted hazard ratios (HRs) for participants had PRISm findings (vs normal spirometry findings) were 1.26 (95% CI, 1.17-1.35) for MACE, 1.12 (95% CI, 1.01-1.25) for MI, 1.88 (95% CI, 1.72-2.05) for HF, 1.26 (95% CI, 1.13-1.40) for stroke, and 1.55 (95% CI, 1.37-1.76) for CVD mortality, respectively. A total of 22,781 participants underwent follow-up spirometry after an average of 8.9 years. Trajectory analysis showed that persistent PRISm findings (HR, 1.96; 95% CI, 1.24-3.09) and airflow obstruction (HR, 1.43; 95% CI, 1.00-2.04) was associated with a higher incidence of MACE vs consistently normal lung function. Compared with persistent PRISm findings, changing from PRISm to normal spirometry findings was associated with a lower incidence of MACE (HR, 0.42; 95% CI, 0.19-0.99). INTERPRETATION: Individuals with baseline or persistent PRISm findings were at a higher risk of diverse cardiovascular outcomes even after adjusting for a wide range of confounding factors. However, individuals who transitioned from PRISm to normal findings showed a similar cardiovascular risk as those with normal lung function.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune disease. Soufeng sanjie formula (SF), which is composed of scolopendra (dried body of Scolopendra subspinipes mutilans L. Koch), scorpion (dried body of Buthus martensii Karsch), astragali radix (dried root of Astragalus membranaceus (Fisch.) Bge), and black soybean seed coats (seed coats of Glycine max (L.) Merr), is a traditional Chinese prescription for treating RA. However, the mechanism of SF in treating RA remains unclear. This study was aim to investigate the anti-arthritic effects of SF in a collagen-induced arthritis (CIA) mouse model and explore the mechanism by which SF alleviates arthritis in CIA mice. METHODS: For in vivo studies, female DBA/1J mice were used to establish the CIA model, and either SF (183 or 550 mg/kg/day) or methotrexate (MTX, 920 mg/kg, twice/week) was orally administered to the mice from the day of arthritis onset. After administration for 30 days, degree of ankle joint destruction and serum levels of IgG and inflammatory cytokines were determined. The balance of Th17/Treg cells in the spleen and lymph nodes was analyzed using flow cytometry. Moreover, the expression levels of retinoic acid receptor-related orphan nuclear receptor (ROR) γt and phosphorylated STAT3 (pSTAT3, Tyr705) in the spleen were detected by immunohistochemistry. Furthermore, the effect of SF on Th17 cells differentiation in vitro was investigated in CD4+ T cells under Th17 polarization conditions. RESULTS: SF decreased the arthritis score, ameliorated paw swelling, and reduced cartilage loss in the joint of CIA mice. In addition, SF decreased the levels of bovine collagen-specific IgG in sera of CIA mice. SF decreased the levels of inflammatory cytokines (TNF-α, IL-6, and IL-17A) and increased the level of IL-10 both in the sera and the joint of CIA mice. Moreover, SF treatment rebalanced the Th17/Treg ratio in the spleen and lymph nodes of CIA mice. SF also reduced the expression levels of ROR γt and pSTAT3 (Tyr705) in the spleen of CIA mice. In vitro, SF treatment reduced Th17 cell generation and IL-17A production and inhibited the expression of RORγt, IRF4, IL-17A, and pSTAT3 (Tyr705) under Th17 polarization conditions. CONCLUSIONS: Our results suggest that SF exhibits anti-arthritic effects and restores Th17/Treg homeostasis in CIA mice by inhibiting Th17 cell differentiation.
RESUMEN
Chronic obstructive pulmonary disease (COPD) is a chronic, progressive lung disease with few successful treatments, and is strongly associated with cigarette smoking (CS). Since the novel coronavirus has spread worldwide seriously, there is growing concern that patients who have chronic respiratory conditions like COPD can easily be infected and are more prone to having severe illness and even mortality because of lung dysfunction. Loquat leaves have long been used as an important material for both pharmaceutical and functional applications in the treatment of lung disease in Asia, especially in China and Japan. Total flavonoids (TF), the main active components derived from loquat leaves, showed remarkable anti-inflammatory and antioxidant activities. However, their protective activity against CS-induced COPD airway inflammation and oxidative stress and its underlying mechanism still remain not well-understood. The present study uses a CS-induced mouse model to estimate the morphological changes in lung tissue. The results demonstrated that TF suppressed the histological changes in the lungs of CS-challenged mice, as evidenced by reduced generation of pro-inflammatory cytokines including interleukin 6 (IL-6), IL-1ß, tumor necrosis factor α (TNF-α), nitric oxide (NO), and inducible nitric oxide synthase (iNOS) and diminished the protein expression of transient receptor potential vanilloid 1 (TRPV1). Moreover, TF also inhibited phosphorylation of IKK, IκB and NFκB and increased p-Akt. Interestingly, TF could inhibit CS-induced oxidative stress in the lungs of COPD mice. TF treatment significantly inhibited the level of malondialdehyde (MDA) and increased the activity of superoxide dismutase (SOD). In addition, TF markedly downregulated TRPV1 and cytochrome P450 2E1 (CYP2E1) and upregulated the expression of SOD-2, while the p-JNK level was observed to be inhibited in COPD mice. Taken together, our findings showed that the protective effect and putative mechanism of the action of TF resulted in the inhibition of inflammation and oxidative stress through the regulation of TRPV1 and the related signal pathway in lung tissues. It suggested that TF derived from loquat leaves could be considered to be an alternative or a new functional material and used for the treatment of CS-induced COPD.

BACKGROUND: Xiao Yao San (XYS) is thought to be beneficial for the treatment of hypertension in China. PURPOSE: A systematic review and meta-analysis was performed to evaluate the efficacy and safety of XYS in hypertension. STUDY DESIGN: A comprehensive literature search was conducted in 7 electronic databases for randomized controlled trials from their inception until January 7, 2019. METHODS: Methodological quality was assessed independently using the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: A total of 17 trials including 1460 hypertensive patients met the selection criteria. Pooled analysis favored XYS plus antihypertensive drugs on blood pressure (BP), Hamilton anxiety scale, self-rating anxiety scale, self-rating depression scale, 9-item patient health questionnaire scale, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, homocysteine, and C-reactive protein. No significant difference between XYS plus antihypertensive drugs and antihypertensive drugs on major cardiovascular and cerebrovascular events was identified. XYS was well tolerated in the treatment of hypertension. CONCLUSION: XYS adjuvant to antihypertensive drugs maybe beneficial for hypertensive patients in lowering BP, improving depression, regulating blood lipids, and inhibiting inflammation. However, the efficacy and safety of XYS are still uncertain due to methodological shortcomings. More long-term, randomized, double-blinded clinical trials are needed in future studies.

Background. Yupingfeng Pulvis (HFBP) had played an active role in many diseases, especially respiratory tract infections. Exploring the possible prevention mechanism of HFBP may provide new ideas in clinical applications for this well-known herbal formula. Purpose. To study the possible mechanisms of therapy effect of HFBP on asthma mice via regulating the balance of Tregs and Th17 cells. Method. The female BALB/c mice were divided into five groups: control group, model group, prednisone (5.5 mg/kg) group, and 22 g/kg HFBP and 44 g/kg HFBP groups. Ovalbumin was used to make the asthma model of mice; the drug was ig administered daily after atomization for consecutive 15 d. The mice were killed after the last administration. The paraffin-embedded tissue sections of the lungs were stained by H&E. Tregs and Th17 cells in bronchoalveolar lavage fluid were detected by flow cytometry. IL-4, TGF-ß, and TNF-α in the serum were detected by ELISA assay. Results. HFBP could alleviate the inflammation in the lung tissue of mice, decrease the proportion of Th17 cells, and increase the proportion of Treg cells in bronchoalveolar lavage fluid. HFBP could decrease IL-4 and TNF-α level and increase TGF-ß level in blood. Conclusion. HFBP could treat the asthma through impacting the balance of Th17 cells and Treg cells as well as the levels of related inflammatory cytokines in asthma mice.
RESUMEN
Observation of tongue coating, a foundation for clinical diagnosis and treatment in traditional Chinese medicine (TCM), is a major indicator of the occurrence, development, and prognosis of disease. The biological basis of tongue diagnosis and relationship between the types and microorganisms of tongue coating remain elusive. Thirteen chronic erosive gastritis (CEG) patients with typical yellow tongue coating (YTC) and ten healthy volunteers with thin white tongue coating (WTC) were included in this study. Patients were provided a 2-course targeted treatment of a herbal medicine Ban Xia Xie Xin decoction, traditionally prescribed for CEG patients with YTC, to evaluate the relationship between tongue coating microbiota and diagnosis of CEG with typical YTC. The tongue coating segregation structure was determined using Illumina Miseq sequencing of the V4-V5 region of the 16S ribosomal RNA gene. Bacillus was significantly observed only in CEG patients with YTC, but not in patients who received the decoction. YTC (n = 22) and WTC (n = 29) samples were collected for bacterial culturing to illustrate the relationship between Bacillus and YTC. The Bacillus positivity rate of YTC samples was 72.7%; Bacillus was not observed in WTC samples. In conclusion, Bacillus was strongly associated with YTC.

Objectives. To assess the clinical effectiveness and adverse effects of Zhen Gan Xi Feng Decoction (ZGXFD) for essential hypertension (EH). Methods. Five major electronic databases were searched up to August 2012 to retrieve any potential randomized controlled trials designed to evaluate the clinical effectiveness of ZGXFD for EH reported in any language, with main outcome measure as blood pressure (BP). Results. Six randomized trials were included. Methodological quality of the trials was evaluated as generally low. Four trials compared prescriptions based on ZGXFD with antihypertensive drugs. Meta-analysis showed that ZGXFD was more effective in BP control and TCM syndrome and symptom differentiation (TCM-SSD) scores than antihypertensive drugs. Two trials compared the combination of modified ZGXFD plus antihypertensive drugs with antihypertensive drugs. Meta-analysis showed that there is significant beneficial effect on TCM-SSD scores. However, no significant effect on BP was found. The safety of ZGXFD is still uncertain. Conclusions. ZGXFD appears to be effective in improving blood pressure and hypertension-related symptoms for EH. However, the evidence remains weak due to poor methodological quality of the included studies. More rigorous trials are warranted to support their clinical use.
