ABSTRACT
This paper explores the interpretation of Jichuan Decoction （济川煎） by tracing its name's origin， exa-mining the original texts of herbs in the decoction within Jingyue's Complete Works（《景岳全书》）， exploring the debate on the sovereign drug of Danggui （Angelica sinensis ［Oliv.］ Diels） and Roucongrong （Cistanche deserticola Y.C. Ma）， and analyzing the historical discussions on the efficacy of the decoction. It is believed that the original meaning of the name Jichuan Decoction （济川煎） refers to its strategy for treating “deficiency constipation”， which can be described as “increasing water to navigating the boat”. Danggui （Angelica sinensis ［Oliv.］ Diels） is considered the sovereign herb for nourishing blood and moistening dryness， while Roucongrong （Cistanche deserticola Y.C. Ma） serves as the minister herb for moistening the intestines and promoting bowel movements. It is concluded by the author that Jichuan Decoction （济川煎） does not primarily focus on warming the kidneys and assisting yang， but rather emphasizes nourishing blood， moistening dryness， and promoting bowel movements. Its main indication is constipation due to deficiency of yin and blood， which is supported by evidence from antiquarian materials.
ABSTRACT
@#As the smallest combination unit of Chinese medicinals， herbal pairs serve as the bridge between medicinals and formulas， whose combination theory reflects the basic characteristics of Chinese medicinals combination and the core essence of prescription composition. Simultaneously， as a key combination of medicinals in clinical treatment of diseases， syndromes， and symptoms， herbal pairs are the main form of clinical medication in traditional Chinese medicine （TCM） as well as the characteristic advantage of treating diseases. This article summarized that “mutual complement of medicinals of same or antagonism flavor and nature” theory is the theoretical origin， and efficacy-enhancement and toxicity-attenuation is the core purpose of the combination of herbal pairs. The property theory of Chinese medicinals and the thought of differentiation and treatment are the main basis of the combination of herbal pairs， and pertinence and flexibility are the key points in clinical application. All mentioned above are expected to provide theoretical guidance for the clinical use and modern research of herbal pairs.

ObjectiveTo observe the effect of salvianolate on the protein expressions of adenosine monophosphate （AMP）-activated protein kinase （AMPK）， silent information regulator 1 （SIRT1） and peroxisome proliferator-activated receptor-γ coactivator-1α （PGC-1α）， autophagy and apoptosis in kidney tissue of rats with membranous nephropathy （MN）， and to explore its possible molecular mechanism against MN. MethodEighty male SD rats were randomly divided into normal group， model group， benazepril hydrochloride group （10 mg·kg-1）， and salvianolate low-， medium-， and high-dose groups （16.7， 33.3 and 66.7 mg·kg-1）. The rats were modeled by injection of cationized bovine serum albumin （C-BSA） into the tail vein. After successful modeling， rats in the administration groups were given corresponding doses of drugs for 4 consecutive weeks， and then 24-hour urine， serum and kidney tissue were collected for the detection of 24-hour urinary protein （UTP）， blood urea nitrogen （BUN）， serum creatinine （SCr）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， C reactive protein （CRP）， glutathione peroxidase （GSH-Px）， superoxide dismutase （SOD）， and malondialdehyde （MDA）. The pathological changes of kidneys were observed by light microscope， electron microscope and immunofluorescence. Western blot was used to detect the protein expressions of phospho-AMPK （p-AMPK）， AMPK， phospho-SIRT1 （p-SIRT1）， SIRT1 and PGC-1α in rat kidney tissue. The protein expressions of autophagy-specific gene （Beclin-1）， microtubule-associated protein 1 light chain 3 （LC3） Ⅱ， ubiquitin-binding protein （p62）， B cell lymphoma （Bcl-2）， Bcl-2-associated X （Bax）， and cysteine aspartic protease-7 （Caspase-7） in rat kidney tissue were determined by immunohistochemistry （IHC）. ResultCompared with the conditions in the normal group， the levels of UTP， IL-6， TNF-α， CRP and MDA in the model group were increased （P<0.05） while the levels of SOD and GSH-Px were decreased （P<0.05）， and there was no difference in BUN and SCr. Compared with the model group， the administration groups had lowered UTP， IL-6， TNF-α， CRP and MDA （P<0.05） while elevated SOD and GSH-Px （P<0.05）. It could be seen from hematoxylin and eosin （HE） staining， Masson staining， immunofluorescence and electron microscopy that the pathological damage of rat kidney tissue in the model group was significant， but after treatment with benazepril hydrochloride and salvianolate， the pathological damage of kidney cells was gradually improved. The expressions of p-AMPK/AMPK， p-SIRT1/SIRT1， PGC-1α， Bcl-2， Beclin-1 and LC3Ⅱ in rat kidney in the model group were lower than those in the normal group （P<0.05） while the expressions of Bax， Caspase-7 and p62 were higher （P<0.05）. Compared with the model group， benazepril hydrochloride group and salvianolate groups had an up-regulation in the expressions of p-AMPK/AMPK， p-SIRT1/SIRT1， PGC-1α， Bcl-2， Beclin-1 and LC3Ⅱ in the kidney （P<0.05） while a down-regulation in the expressions of Bax， Caspase-7 and p62 （P<0.05）. ConclusionThe protective effect of salvianolate on the kidneys of MN rats may be related to the activation of AMPK/SIRT1/PGC-1α signaling pathway， the up-regulation of autophagy and the reduction of apoptosis.
ABSTRACT
ObjectiveTo observe the intervention effect of Dahuang Xiezhuo prescription （DHXZ） on inflammation and suppressor of cytokine signaling 3 （SOCS3）/Toll-like receptor 4 （TLR4） pathway in rats with chronic renal failure （CRF）， and to explore its molecular mechanism in alleviating renal inflammatory response. MethodThe 90 male SD rats， 15 were randomly selected as sham group， and the remaining 75 were used as modeling group to replicate CRF rat model by 5/6 nephrectomy. After successful modeling， the rats were randomly divided into model group， DHXZ low-， medium-， high-dose groups （6.825， 13.65， 27.3 g·kg-1） and Niaoduqing Granules group （2.6 g·kg-1）. The drug intervention groups received corresponding drugs by gavage for 8 consecutive weeks. After administration， hematoxylin-eosin （HE） staining and Masson staining were used to observe the morphological changes of rat renal tissue， and blood creatinine （SCr）， blood urea nitrogen （BUN） and blood uric acid （UA） were tested. Enzyme-linked immunosorbent assay （ELISA） was performed to detect the serum contents of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） and C-reactive protein （CRP）. The mRNA expressions of SOCS3 and TLR4 in renal tissue were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and the protein expressions of SOCS3， TLR4， nuclear transcription factor （NF-κB） and myeloid differentiation factor （MyD88） were detected by Western blot. Immunohistochemistry was used to determine the protein expressions of NF-κB， MyD88， NOD-like receptor protein 3 （NLRP3） and melanoma deficiency factor 2 （AIM2）. ResultCompared with the sham group， the model group had a significant inflammatory response in renal tissue， and an increase in blood SCr， BUN， UTP， IL-6， TNF-α and CRP （P<0.05）. The protein and mRNA expressions of SOCS3 in renal tissue of rats in the model group were lower while the protein expressions of TLR4， NF-κB， MyD88， NLRP3 and AIM2 and the mRNA expression of TLR4 were higher than those in the sham group （P<0.05）. Compared with the model group， DHXZ and Niaoduqing granules groups presented markedly reduced inflammatory response in renal tissue and decreased blood SCr， BUN， UTP， IL-6， TNF-α and CRP （P<0.05）. Additionally， DHXZ and Niaoduqing granules up-regulated the protein and mRNA expressions of SOCS3 in renal tissue while down-regulated the protein expressions of TLR4， NF-κB， MyD88， NLRP3 and AIM2 and the mRNA expression of TLR4 （P<0.05）. ConclusionDHXZ can reduce the release and expression of inflammatory factors， inhibit the inflammatory response and improve renal function， and the mechanism may be related to the regulation of SOCS3/TLR4 signaling pathway.
ABSTRACT
ObjectiveTo observe the effect of Dahuang Xiezhuo prescription on the clinical symptoms， blood uric acid， and renal tubular function of patients with immunoglobulin A （IgA） nephropathy in stages 1-2 of chronic kidney disease （CKD） complicated with hyperuricemia （HUA）. MethodSixty patients with IgA nephropathy in stages 1-2 of CKD complicated with HUA of spleen and kidney deficiency and combined turbidity and blood stasis syndromes were randomly divided into an observation group and a control group， with 30 cases in each group. The patients in the control group received basic treatment， i.e.， losartan potassium tablets 50-100 mg/time， once per day， and sodium bicarbonate tablets 0.5 g/time， three times per day by oral administration， combined with low-salt， low-fat， and low-purine diet. The patients in the observation group received Dahuang Xiezhuo prescription on the basis of basic treatment， one dose per day， twice a day in the morning and evening with warm water. Both groups were treated for two months. The total scores of traditional Chinese medicine（TCM）syndrome， blood pressure， 24 h urinary protein （24 h UTP）， blood urea nitrogen （BUN）， serum creatinine （SCr） ［glomerular filtration rate （eGFR） was calculated by CKD-epidemiology collaboration （CKD-EPI） formula］， serum uric acid （SUA）， and renal tubular function indexes ［urinary α1-microglobulin （α1-MG）， urinary β2-microglobulin （β2-MG）， urinary kidney injury molecule-1 （KIM-1）， and neutrophil gelatinase-associated lipocalin （NGAL）］ of the two groups before treatment and two months after treatment were recorded. The clinical efficacy of the two groups was evaluated two months after treatment. ResultAfter 2 months of treatment，the total effective rate in the observation group was 81.48%（22/27），higher than 50.00%（14/28） in the control group（χ2 =6.661，P<0.05）. The total scores of TCM syndrome， 24 h UTP， and SUA in the observation group and the observation group were lower than those before treatment （P<0.05）， and compared with the control group after treatment， the observation group decreased more significantly （P<0.05）. After treatment， the blood pressure in the observation group and the observation group was lower than that before treatment （P<0.05）， and there was no significant difference in blood pressure between the two groups after treatment. After treatment， the levels of urinary α1-MG， β2-MG， KIM-1， and NGAL in the two groups were lower than those before treatment （P<0.05）， and the observation group was lower than the control group after treatment （P<0.05）. There were no significant inter-group and intra-group differences in BUN， SCr， and eGFR levels before and after treatment. There were no obvious abnormalities in blood routine， liver function， and electrolytes before and after treatment in the two groups， and no adverse reactions such as allergies occurred. ConclusionDahuang Xiezhuo prescription can effectively improve the clinical symptoms of IgA nephropathy with HUA （CKD1-2） patients with spleen and kidney deficiency and combined turbidity and blood stasis syndromes， reduce blood uric acid level， alleviate renal tubular injury， and protect the kidney. The curative effect is better than that of basic treatment.

ABSTRACT
ObjectiveTo observe the effect of Dahuang Xiezhuo prescription on the changes in renal pathology and reactive oxygen species （ROS）/thioredoxin-interacting protein （TXNIP）/NOD-like receptor protein 3 （NLRP3） pathway expression in the kidney tissues of rats with 5/6 nephrectomy， and to explore the mechanism of Dahuang Xiezhuo prescription in protecting renal function and delaying renal interstitial fibrosis and the possibility. MethodNinety healthy male SD rats were randomly divided into a sham operation group， a model group， low， medium， and high-dose （6.825， 13.65， 27.30 g·kg-1） Dahuang Xiezhuo prescription groups， and a Niaoduqing granule group （2.60 g·kg-1）. Except the sham operation group， 5/6 nephrectomy was used to replicate the rat model of chronic renal failure （CRF）. After modeling， each administration group was given the corresponding dose of drug suspension by intragastric administration， once a day for consecutive 8 weeks. After administration， serum creatinine （SCr） and urea nitrogen （BUN） levels and 24 h urinary protein quantification （UTP） levels were detected. Western blot assay was used to detect the protein expressions of thioredoxin （TRX）， TXNIP， and NLRP3. The protein expressions of TRX， TXNIP， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， transformation growth factor-β （TGF-β）， Collagen Ⅳ， α-smooth muscle actin （α-SMA）， and fibronectin （FN） were detected by immunohistochemistry. ResultAs compared with the sham operation group， serum levels of SCr， BUN， and UTP in the model group were increased （P<0.05）， TRX， TXNIP， NLRP3， ASC， TGF-β， Collagen Ⅳ， α-SMA， and FN proteins were increased （P<0.01）， and renal interstitial fibrosis significantly occurred. As compared with the model group， the levels of SCr， 24 h BUN， and UTP in the low， medium， and high-dose Dahuang Xiezhuo prescription groups and the Niaoduqing granule group were decreased to varying degrees （P<0.05）， TRX， TXNIP， NLRP3， ASC， TGF-β， Collagen Ⅳ， α-SMA， and FN were decreased （P<0.01）， and renal interstitial fibrosis was improved to varying degrees. ConclusionDahuang Xiezhuo prescription can protect renal function and delay renal interstitial fibrosis in rats with CRF.
ABSTRACT
Traditional Chinese medicine (TCM) has a long history in treating infectious diseases, and the form of intervention varies with different medical conditions and disease types. "The battle field of Chinese doctor for anti-epidemic" was formed in fighting against severe acute respiratory syndrome (SARS) epidemics in China, and from the battle, valuable experiences of using TCM for prevention and treatment had been obtained. During responding to coronavirus disease 2019 (COVID-19) epidemics, we followed the principle of keeping summary and perfection while treament. And a whole process of TCM pattern or a model was organized, including early prevention in communities, cluster intervention in isolated places, comprehensive intervention in mobile cabin hospitals, centralized treatment in designated hospitals and rehabilitation support in rehabilitation posts. Thus, the innovation of whole process of TCM intervention was involved in the "trench warfare" strategy and platform system for prevention and treatment of new infectious COVID-19 epidemics. At different stages or conditions, different TCMs were used to play advantageous roles to solve various problems and elevate the effects of prevention and treatment of the disease. The construction of TCM mobile cabin hospitals was an innovation of organization form that might offset the constraints in technology and scale of simple community isolation or simple hospital treatment, exploring a new way for TCM to cope with public health emergencies.
ABSTRACT
Objective To assess the clinical effectiveness and safety of relinqing pharmaceutical preparations for the treatment of uncomplicated urinary tract infection(UTI). Methods The genitourinary infection, urinary tract infection, pyelonephritis, cystitis, stranguria and urethritis were used as key words to search at CNKI,VIP,SinoMed,PubMed,Wan Fang and Cochrane Library Databases up to April 2015. Data of randomised controlled trials (RCTs) comparing treatments using relinqing were included in this study. The quality of the literature was evaluated by the method of Cochrane handbook 5.1.0. Data extraction was carried out independently by two authors. RevMan 5.2 software was used for Meta-analysis. Results Five RCTs were included that involved a total of 471 uncomplicated UTIs. Analysis of four studies showed a higher rates of effectiveness for uncomplicated UTI in the treatment with relinqing plus antibiotics than those of antibiotics alone [RR and 95%CI:1.15 (1.08-1.23), P<0.001]. Analysis of two studies showed a higher rates of bacterial clearance for uncomplicated UTI in the treatment with relinqing plus antibiotics than those of antibiotics alone [RR and 95% CI: 4.04 (1.78-9.16)]. Conclusion Data from five small studies suggest that relinqing as an independent intervention or in conjunction with antibiotics may be beneficial for treating uncomplicated UTIs. However, the small number and poor quality of the included studies meant that it is not possible to formulate robust conclusion on the use of relinqing for uncomplicated UTI either alone or as an adjunct to antibiotics.
