Objective. is study intended to systematically evaluate the eectiveness and safety of modied Dachengqi Decoction (MDD)
combined with conventional treatment for treating acute exacerbation of chronic obstructive pulmonary disease (AECOPD).
Method. An extensive search was performed within English and Chinese electronic databases from inception to April .
Methodological quality was assessed according to Cochrane risk of bias assessment. Data were analyzed using Review Manager ..
Results. A total of studies (involving patients) were included. e result showed that MDD and its modication combined
with routine treatment were more eective in improving FEV1%pred, enhancing the signicant eectiveness, reducing PCO2,
and shortening duration of mechanical ventilation. Adverse events were reported in two trials with symptom of diarrhea, while
no serious adverse eect was reported. Conclusion. Modied Dachengqi Decoction appears to be eective for treating AECOPD.
However, more regular designed RCTs are needed because of insucient methodological problems.
1. Introduction
Global strategy for the diagnosis, management, and preven-
tion of chronic obstructive pulmonary disease (COPD) []for
the rst time revised the goal of the treatment of COPD into
relief symptoms rapidly, and reduces risk of patients’ health,
such as recurrent episodes or rapid decrease of pulmonary
function []. erefore, how to control the symptoms and
reduce the frequency of disease onset became the research
emphasis in academic eld.
COPD belongs to the category of “lung distention” in
Chinese medicine. Syndrome of phlegm-heat obstructing
in the lung is one of the most common syndromes in the
acutestage.emainclinicalfeaturesincludeyellowsputum,
dyspnea, thirsty, and constipation []. “Interior and Exterior
Relationship between the Lung and Large Intestine” is one
of the most typical viscera correlation theories. It describes
the corelationship of viscera, meridian, physiological relation,
and pathological changes, which is the foundation for
further clinical treatment of AECOPD by using purgative
drugs. Many domestic and foreign researches [,]found
that COPD patients have digestive tract symptom such as
abdominal distension, constipation besides cough, wheezing,
phlegm, and dyspnea. So, it is viable to do research on using
purgativedecoctioninthetreatmentofAECOPD.
Dachengqi decoction, a representative recipe of dredging
intestines in Treatise on Febrile Diseases (Shang Han Lun),
hasbeenwidelyusedtotreatYangmingFushiSyndrome.
It is composed by Rheum, Magnolia ocinalis,immature
bitter orange, and Mirabilite. In a recent study, it eectively
treated critical patients with gastroenteric function disorder,

is study aimed to determine the eects and safety of

decoctions, or Chinese patent medicine based on Dachengqi
Decoction plus conventional treatment compared with
western medicine alone in the treatment of AECOPD.
2. Materials and Methods
2.1. Search Strategy. We searched the Chinese literature from
CNKI,CBM,VIP,WANFANG,andforeignliteraturefrom
PubMedandCochranelibrary.esearchingwasfromthe
inception of the databases to April . We utilized the
medical subject headings “COPD” or “chronic obstructive
pulmonary disease” and “Chinese medicine” in PubMed,
Cochrane, while we use “COPD” or “chronic obstructive
pulmonary disease” and “Dachengqi Decoction” or “Radix et
Rhizoma Rhei” or “Natrii Sulfas” or “Fructus Aurantii Immat-
urus” or “Cortex Magnoliae ocinalis” in Chinese database.
2.2. Inclusion Criteria. Inclusion criteria were the following:
() RCTs in English or Chinese involving decoctions based on
Dachengqi Decotion compared with placebo, no treatment,
or conventional treatment without Chinese medicine as
controls. () Patients must be aged years or over and of any
gender or ethnic origin. Patients are diagnosed with COPD
in the severe stage with or without respiratory failure. COPD
is dened as “e Global Initiative for Chronic Obstruc-
tive Lung Disease (GOLD)” which is pulmonary function
includes FEV1%pred <% and FEV1/FVC% <% aer
using bronchodilator. () Primary outcome measures were
pulmonary function (FEV1%pred, FEV1/FVC%), safety, and
signicant eectiveness based on clinical symptoms relief.
e signicant eectiveness was dened as the symptoms
scores improvement rate ≥% according to “the guide for
clinical trials of new drugs” []. Clinical symptoms involved
cough, cough-up phlegm, dyspnea, constipation, and wheeze.
Secondary outcome measures were artery blood gas analysis
(PO2,PCO
2) and duration of mechanical ventilation.
2.3. Data Extraction. Study characteristics included trial
design, sample size, mean and standard deviation of partic-
ipants’ age, and history of COPD; severity of COPD dier-
entiation of syndrome, methodological quality, intervention,
outcome measures, treatment duration and follow-up period,
and adverse events were extracted to a predened form and
checked by a second reviewer.
2.4. Risk of Bias. e methodological quality of the included
studies was independently assessed by authors using
theCochraneriskofbiasassessment[]. Assessment of
Cochrane risk of bias consists of seven domains: () random
sequence generation () allocation concealment () blinding
of participants and personnel () blinding of outcome assess-
ment () incomplete outcome data () selective reporting and
() other bias. For each domain, evaluation was by denoting
“yes”-adequate (low risk of bias); “no”: inadequate (high risk
of bias); or “unclear”: unclear or not used (uncertain risk of
bias) according to the descriptions of the method in each
study. Any disagreement was resolved by discussion with a
third reviewer.
2.5. Data Analysis. Meta-analysis was performed using Rev-
Man .. For categorical data, we used risk ratios (RR),
while for continuous data, mean dierences (MD) were
calculated and expressed in eect value and % condence
(CI). Heterogeneity was calculated by 𝑋2and 𝐼2statistics.
When heterogeneity inspection result showed signicant
heterogeneity (𝑃 < 0.05), we used random eects model,
otherwise we applied xed eects model.
3. Results
3.1. Overview of Included Studies. We initially identied
citations, aer screening for potential relevance, full papers
[–] were assessed for possible inclusion (Figure ). All
studies were conducted in China. e characteristics of the
included studies are summarized in Tab l e . e dierent
compositions of Chinese herbal formula MDD are presented
in Table . e studies involved a total of acute COPD
patients, and studies were included in meta-analysis. All
studies reported diagnosis standard. All studies were about
Chinese medicine combined with western medicine rou-
tine treatment compared with conventional treatment alone
(Table ). Fieen studies [–,–,–]wereabout
oral decoction combined with western medicine routine
treatment. Two [,] studies used Chinese patent medicine
based on MDD.
3.2.AssessmentofRiskofBias. Information of sequence gen-
eration was adequate for ve studies at low risk of bias [,,
,,] and inadequate for seventeen studies with unclear
risk of bias [–,–,–,]. All the ve studies
reported that they used random number table for sequence
generation. Allocation concealment was not reported in all
studies (no). Blinding of participants, physicians, and study
personnel was not reported in these studies, but all studies
were carried without placebo, so they were of high risk of
bias.Noneofthestudiesreportedlosttofollowup,withdraw
and dropo; thus, the risk of bias of incomplete outcome
data over all studies was graded as unclear. As far as selective
reporting was concerned, for we could not nd any pre-
dened outcome measurements in all the included studies
we classied them as unclear risk of bias. Due to the limited
number of included studies, we were not able to implement
funnel plot.

symptoms in TCM. e theory of “Interior and Exterior
Relationship between the Lung and Large Intestine” is one of
the most important theories in traditional Chinese Medicine
which is of great value in the clinical practice. Also some
studies found that “catharsis large intestine” can decrease T
cells and enhance the number of serum T cells and aect the
balance of CD+and CD+and can have eects on airway
remodeling of lung in rats with COPD [].
Also, there are several methodological limitations. First,
all trials involved were of low quality. No study applied
placebo as control; thus, the patients and physicians were
not blinded. Although all the trials reported randomization,
only studies reported sequence generation and no study
addressed the issue of allocation concealment. e quality
of studies published in Chinese is majorly poor, and some
scholars indicated that China generated virtually no negative
studies at all []. erefore, the ndings of the meta-
analyses should be interpreted with caution. Due to the
time limitation, we did not contact the original authors, and
furtherinformationforbetterevaluationofriskofbiaswas
inadequate.

so there might be a potential publication bias. We could
notruleoutthesystematicerrorbecausethesamplesize
of all studies was limited. So the clinical eect might be
exaggerated. Larger sample RCTs are needed in the future for
accurate results.
ird,allthedecoctionsincludedintheresearchwere
based on Dachengqi Decoction, but the herbs and the
dosages were dierent in each study. is might be the
main reason leading to the signicant heterogeneity. We can
see in the research that all the studies except six pointed
out that the syndrome of phlegm-heat obstructing lung is
appropriate for MDD. Determination of treatment based on
pathogenesis obtained through dierentiation of symptoms
is one of the most important characteristics in Chinese
Medicine, so modication according to symptoms is needed
during the treatment. Herbs of cold nature such as Gypsum
Fibrosum or Radix Scutellariae are used to clear heat while
diminishing sputum herbs such as Fructrs Trichosanthis,
Semen Lepidii, and Herba Houttuyniae are commonly used
in patients with abundance phlegm on the basic of Dachengqi
Decoction.
Despite of the methodological weakness and potential
risk of bias, the data from the included studies illustrated
that MDD combined with conventional treatment may
have better eectiveness than conventional treatment alone,
especially in improving FEV1%pred, enhancing signicant
eectiveness, reducing PCO2, and shortening duration of
mechanical ventilation. e study suggests that MDD could
improve airway obstruction and relieve respiratory failure so
as to improve prognosis.
5. Conclusion
Modied Dachengqi Decoction appears to be eective for
treating AECOPD. However, more well-designed and large
sample RCTs are needed in the future due to the insucient
methodological problems of existing studies.
