Quality evaluation of Bupleuri Radix in Shanxi Province by LC-MS based pseudotargeted metabonomics / 药学学报

Bupleuri Radix is commonly used in the traditional Chinese medicine, and saikosaponins are the important active ingredients. In this study, we first established a relative quantitative method for 25 saikosaponins using ultra high performance liquid chromatography-triple quadrupole mass spectrometry (UHPLC-QTrap-MS) in the scheduled multiple reaction monitoring (sMRM) mode. The established method showed good intra-day and intra-day precision, linearity, repeatability and stability. Then the method was applied to compare 37 batches of Bupleuri Radix from different planting areas. The results showed that there was no significant difference in the saikosaponins composition of Bupleuri Radix from different planting areas in Shanxi Province, which indicating that Bupleuri Radix is well adapted to the environment, so it is suitable for widely planting. However, Bupleuri Radix harvested at spring and autumn were differed from those harvested at summer, which indicated that the traditional harvesting experience was reasonable. Correlation analysis showed that saikosaponins a and d were positively correlated with some saponins, and 4 saponins (such as clinoposaponin XII) showed bigger content variation were identified by coefficient of variation analysis. The LC-MS based pseudotargeted metabonomic method established in this study can be applied to the comprehensive detection of saikosaponins, which providing new method for the quality evaluation of Bupleuri Radix.

The rules of acupoint selection of acupuncture and moxibustion for scrofula in ancient times / 中国针灸

Based on data mining technology, the rules of acupoint selection of acupuncture-moxibustion for scrofula in ancient times were analyzed. The relevant articles of acupuncture and moxibustion for scrofula were searched in the Chinese Medical Code, and the original article, acupoint name, acupoint characteristic, and acupoint meridian tropism, etc. were screened and extracted. The Microsoft Excel 2019 was used to establish a acupoint prescription database, and the frequency of acupoints as well as their meridian tropism and characteristics were analyzed. The SPSS21.0 was applied to perform cluster analysis of acupuncture prescriptions; the SPSS Modeler 18.0 was used to perform the association rules analysis of the neck and the chest-armpit acupoints, respectively. As a result, 314 acupuncture prescriptions were extracted, including 236 single-acupoint prescriptions and 78 multiple-acupoints prescriptions (53 for neck and 25 for chest-armpit). A total of 54 acupoints were involved, with a total frequency of 530. The top 3 commonly-used acupoints were Tianjing (TE 10), Zulinqi (GB 41) and Taichong (LR 3); the most commonly-used meridians were hand shaoyang meridian, foot shaoyang meridian, hand yangming meridian and foot yangming meridian; the most commonly-used special acupoints were he-sea points and shu-stream points. The cluster analysis obtained 6 clusters, and the association rule analysis obtained that the core prescriptions of the neck were Quchi (LI 11), Jianyu (LI 15), Tianjing (TE 10) and Jianjing (GB 21), while the core prescriptions of the chest-armpit were Daling (PC 7), Yanglingquan (GB 34), Danzhong (CV 17), Jianjing (GB 21), Waiguan (TE 5), Zhigou (TE 6), Yuanye (GB 22) and Zhangmen (LR 13). The core prescriptions obtained from association rule analysis by difference areas were basically consistent with those by cluster analysis of total prescriptions.

Quality evaluation of Galli Gigerii Endothelium Corneum based on HPLC fingerprints and content determination of nucleosides / 中国中药杂志

Galli Gigerii Endothelium Corneum(GGEC), the dried gizzard membrane of Gallus gallus domesticus is a Chinese medicinal material commonly used for digestion. However, due to the particularity of texture and composition, its active ingre-dients have not been clarified so far, and there is also a lack of quality evaluation indicators. In this study, UPLC-Q-TOF-MS was used to analyze the chemical components from the water extract of GGEC, and ten nucleosides were identified for the first time. HPLC fingerprints of the water extracts of GGEC were established and the content of seven nucleosides was determined. The fingerprint similarities of 40 batches of GGEC samples ranged from 0.765 to 0.959, indicating that there were great differences among the GGEC products processed with different methods. In addition, SPSS 22.0 and SIMCA 14.1 were used for hierarchical cluster analysis(HCA) and principal component analysis(PCA) on the 19 common peaks of the HPLC fingerprints of GGEC, and the 40 batches of samples were divided into three categories: raw GGEC, fried GGEC and vinegar-processed GGEC. Eight differential components in GGEC were marked by orthogonal partial least squares discrimination analysis(OPLS-DA), two of which were adenine and thymine. The results of content determination showed that the total content of the seven nucleosides in raw GGEC, fried GGEC and vinegar-processed GGEC were 182.5-416.8, 205.3-368.7, and 194.2-283.0 μg·g~(-1), respectively. There were significant differences in the content of hypoxanthine, thymine and thymidine among the GGEC products processed with different methods(P<0.05), which were graded in the order of fried GGEC>vinegar-processed GGEC>raw GGEC. This suggested that the content of hypoxanthine, thymine and thymidine tended to increase during the frying process, and the variation range might be related to the degree of heat exposure. The established methods in this study were simple and reproducible, and could be used for qualitative and quantitative analysis of GGEC and its processed pro-ducts. This study also provided reference for the establishment of quality standards of GGEC with chemical components as control index.

Effect and Mechanism of Baoshen Prescription in Alleviating Renal Fibrosis in UUO Mice by Regulating ERK/p38 MAPK Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo observe the protective effect of Baoshen prescription against renal fibrosis and explore its underlying mechanism through network pharmacology， molecular docking， and in vivo experiments. MethodAll mice were randomly divided into sham surgery group， model group， low-， medium-， and high-dose Baoshen prescription groups， and a benazepril hydrochloride group. Unilateral ureteral obstruction （UUO） was performed to establish a renal fibrosis model， and the administration of Baoshen prescription at low， medium， and high doses （0.455， 0.91， and 1.82 g·kg-1）， and benazepril hydrochloride （1.68 mg·kg-1） or distilled water began on the same day as model preparation. Mice in the model group and the sham surgery group were given an equal volume of distilled water. The intervention was carried out once daily for 14 days. Mouse serum levels of blood urea nitrogen （BUN） and creatinine （Cr） were measured. Hematoxylin-eosin （HE） staining and Masson staining were used to observe renal pathological changes. Western blot and immunohistochemistry were used to assess the expression of fibronectin （FN）， α-smooth muscle actin （α-SMA）， and E-cadherin， which are related to renal fibrosis. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to measure the mRNA expression of transforming growth factor-β1 （TGF-β1）， tumor necrosis factor-α （TNF-α）， NOD-like receptor protein 3 （NLRP3）， and monocyte chemoattractant protein-1 （MCP-1） in renal tissues. The mechanism of Baoshen prescription in improving renal fibrosis was explored through network pharmacology， molecular docking， and Western blot experiments. ResultCompared with the sham surgery group， the model group showed significantly increased levels of BUN and Cr （P<0.01）. The model group exhibited abnormal renal glomerular morphology， loss of tubular brush borders， tubular dilation， and an enlarged area of blue collagen fibers. Mice in the model group showed significantly elevated levels of FN and α-SMA （P<0.01）， significantly decreased expression of E-cadherin （P<0.01）， and significantly increased expression of TGF-β1， TNF-α， NLRP3， and MCP-1 mRNA （P<0.05， P<0.01）. Compared with the model group， the Baoshen prescription groups showed significantly reduced BUN and Cr levels （P<0.01）， alleviated renal pathological damage， improved fibrosis， reduced expression of FN and α-SMA （P<0.01）， increased E-cadherin expression （P<0.01）， and downregulated mRNA expression of TGF-β1， TNF-α， NLRP3， and MCP-1 （P<0.05， P<0.01）. Network pharmacology and molecular docking predicted that Baoshen prescription could potentially improve renal fibrosis through the extracellular signal-regulated kinase （ERK）/p38 mitogen-activated protein kinase （MAPK） signaling pathway. Pharmacological research showed that compared with the sham surgery group， the model group exhibited significantly increased expression of phosphorylated （p）-ERK and p-p38 （P<0.05， P<0.01）. Compared with the model group， medium- and high-dose Baoshen prescription groups showed significantly downregulated expression of p-ERK and p-p38 proteins （P<0.05， P<0.01）. ConclusionBaoshen prescription can effectively improve renal fibrosis induced by UUO in mice， and its mechanism of action may be related to the ERK/p38 MAPK signaling pathway.

Analysis on Indications and Medication Regularities of Famous Classical Formula Wuzhuyu Tang Based on Modern Clinical Literature / 中国实验方剂学杂志

Wuzhuyu Tang （WZYT）， a classical traditional Chinese medicine （TCM） formula， was first recorded in Treatise on Cold Damage by the prestigious physician ZHANG Zhong-jing in the Eastern Han Dynasty， and included in Catalogue of Ancient Classical Formulas （First Batch）. WZYT is composed of four medcinals： Euodiae Fructus， Ginseng Radix et Rhizoma， Zingiberis Rhizoma Recens， and Jujubae Fructus， which has the effects of warming the middle and tonifying deficiency， dissipating cold and descending adverse qi. Based on data mining， this paper analyzes the modern clinical research literature on WZYT， which is expected to lay a basis for clarifying the "disease-symptom-prescription-medicinal" relationship of WZYT， as well as its modern clinical indications and clinical dosage. With the search term "Wuzhuyu Tang"， 253 complete medical records were retrieved from CNKI， VIP， and Wanfang （2000-2020）， involving 292 TCM prescriptions. Microsoft Excel 2019 was employed to establish the medical record database and the main clinical indications were statistically analyzed. Moreover， the syndromes， incidence law， and medication regularity were summed up. The result indicates WZYT has a wide range of modern clinical applications， mainly including the treatment of headache， dizziness， vomiting， diarrhea， dysmenorrhea， morning sickness， and other diseases， and the "deficiency， cold， and reversal" symptoms， mainly manifested as nausea and vomiting， headache， fatigue and lack of strength， reversal cold of hands and feet， poor appetite， gloomy complexion， dizziness， aversion to wind and cold， abdominal pain， sloppy diarrhea， abdominal distension， poor sleep， pale tongue， white coating， and deep thread wiry pulse. These diseases and symptoms mainly occur in women and middle-aged people. In most cases， medicinals are added or subtracted according to the symptoms， and the common doses of Euodiae Fructus， Zingiberis Rhizoma Recens， Codonopsis Radix or Ginseng Radix et Rhizoma， and Jujubae Fructus in the original prescription are 6-15 g， 10-15 g， 10-15 g or 9-12 g， and 4-6， respectively.

Views on Key Technical Problems in Research and Development of Famous Classical Formulas / 中国实验方剂学杂志

In this paper， the key technical problems in the research and development of famous classical formulas are analyzed. Firstly， the puzzled problem for a long-time， which is conversion relationship from medicinal metrology of Han dynasty （HD） to that of modern （gram，g）， is comprehensively expounded that one Liang （两） of HD=3 g is more appropriate. Secondly， the model and principles of quality consistency evaluation are given for the transformation from the quality of authoritative basic sample prepared by casserole （ABS-C） to the quality consistency in Laboratory process， pilot-scale process and industrial production. The consistency evaluation model is ξABS-X=K1（Q1ABS-X/Q1ABS-C）+K2（Q2ABS-X/Q2ABS-C）+……+Ki（QiABS-X/QiABS-C）=∑Ki（QiABS-X/QiABS-C）（i=1，2，3……n）. In the formula， ABS-X means laboratory reference sample ABS-C （ABS-L）， pilot-scale ABS-C （ABS-mP） or industrial production ABS-C （ABS-P）， ξABS-X means the quality consistency rate or similarity degree of ABS-L， ABS-mP and ABS-P processes with ABS-C， Ki means the weight of each quality evaluation index （i）， QiABS-X is the data of i in ABS-L， ABS-mP， ABS-P samples， and QiABS-C is the data （or mean） of i in ABS-C sample. Thirdly， in order to control the quality of the herbal medicines whose active ingredients were unknown， their chemical constituents should be studied deeply， and if necessary， the bioassay research should be carried out according to the main efficacy or indication of famous classical formulas. Finally， for the special processing of some herbal medicines， it is difficult to formulate the processing method， technology and standard of prepared slices. It is suggested that the scientific connotation and historical evolution of the special processing method should be thoroughly sorted out， and its technological characteristics are summarized， the modern processing technology and production processes are simulated， and then the corresponding processing methods and quality standards are formulated.

Evaluation and optimization of content determination method of Chrysanthemi Flos in Chinese Pharmacopoeia / 中国中药杂志

This study discovered that the resolution of 3,5-O-dicaffeoylquinic acid(isochlorogenic acid A) in the content determination method of Chrysanthemi Flos in Chinese Pharmacopoeia(ChP)(2020 edition) was poor, which affected accurate quantification. We tested the method in ChP with chromatographic columns of seven brands to clarify the problems in the existing method, optimized the chromatographic conditions by adjusting the mobile phase composition and elution ratio and replacing the chromatographic column packing, and carried out the reproducibility assay for the new method. The two methods were compared for the content determination results of Chrysanthemi Flos prepared from six different varieties. As evaluated by the resolution based on different chromatographic columns of seven brands, the existing method failed to separate isochlorogenic acid A and isochlorogenic acid D well. The peaks of the two components were not completely separated on three chromatographic columns, and isochlorogenic acid A and isochlorogenic acid D generated a co-effluent peak in the other four columns. Isochlorogenic acid A and isochlorogenic acid D could be completely separated under the optimized chromatographic conditions. The difference in the peak areas of isochlorogenic acid A+isochlorogenic acid D obtained by the optimized method and the method in ChP was not significant, with deviation less than 3.0%, which further proved that the result measured by the method in ChP was the co-effluent of isochlorogenic acid A and isochlorogenic acid D. The optimized method can ensure the accurate quantification of isochlorogenic acid A. The existing content determination method of Chrysanthemi Flos has the problem of poor resolution. It is recommended to revise the chromatographic conditions for the content determination method of Chrysanthemi Flos to improve the resolution of isochlorogenic acid A and ensure its accurate quantification.

Comparison of chemical components between aerial and underground parts of Coptis chinensis based on UPLC-Q-TOF-MS~E technology / 中国中药杂志

The ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS~E) technology was employed to compare the chemical components between the aerial and underground parts of Coptis chinensis samples from different batches. According to the retention time, molecular ion peak, and LC-MS~E fragment information of the reference substances and available literature, we identified a total of 40 components. Thirty-three and 31 compounds were respectively identified in the underground part(taproots) and the aerial part(stems and leaves) of C. chinensis. Among them, 24 compounds, including alkaloids(e.g., berberine and jatrorrhizine) and phenolic acids(e.g., chlorogenic acid, quinic acid, and tanshinol), were common in the two parts. In addition, differential components were also identified, such as magnoline glucoside in the underground part and(±) lariciresionol-4-β-D-glucopyranoside in the aerial part. The analysis of fragmentation pathways based on spectra of reference substances indicated the differences among samples of different batches. Furthermore, we performed the principal component analysis(PCA) for the peak areas of C. chinensis in different batches. The results showed that the underground part and the aerial part were clearly clustered into two groups, indicating that the chemical components contained in the two parts were different. Furthermore, the results of partial least squares discriminant analysis(PLS-DA) identified 31 differential compounds(VIP value>1) between the underground part and the aerial part, mainly including alkaloids, phenolic acids, lignans, and flavonoids. This study proves that C. chinensis possesses great development potential with multiple available compounds in stems and leaves. Moreover, it sheds light on for the development and utilization of non-medicinal organs of C. chinensis and other Chinese medicinal herbs.

According to the random number table method, they were divided into the control group and the intervention group with 45 cases each. The control group was given medication, and the intervention group used relaxation training on the basis of the control group. The obsessive-compulsive disorder scores, quality of life, depression, and anxiety of the two groups were compared before and after treatment.Results:The obsessive thinking and compulsive behavior scores of the control group after treatment were (14.02±3.12) and (15.01±2.45) points; the intervention group was (11.91±3.01) and (12.23±2.34) points after treatment, and lower than the control group ( t values were 3.265, 5.504, P<0.05 or 0.01). The quality of life score of the control group after treatment was (283.64±51.28) points; the intervention group was (305.67±49.28) points after treatment, and the intervention group was higher than the control group after treatment (t value was -2.078, P<0.05). After treatment, the scores of the depression scale and anxiety scale of the control group were (12.35±2.89) and (15.35±4.03) points; the intervention group was (8.05±1.72) and (10.35±3.65) points after treatment, and the intervention group after treatment all lower than the control group ( t values were 8.577, 6.169, P<0.01). Conclusion:Using relaxation training combined with conventional drugs to treat patients with obsessive-compulsive disorder can improve obsessive-compulsive symptoms, improve quality of life, and relieve negative emotions.

Pharmacokinetics of the main components differing between Ligustri Lucidi Fructus and its wine-steamed product / 药学学报

A quantitative analysis method for ten principal components (phenylethanol, iridoids and triterpenes) of raw Ligustri Lucidi Fructus and its wine-steamed product was developed using liquid chromatography tandem triple quadrupole mass spectrometry (LC-QQQ-MS) to study their pharmacokinetic behavior in vivo. The results of methodological investigation were in accord with the criteria of biological analysis. After a single administration to rats of the water extracts of Ligustri Lucidi Fructus and its wine-steamed product, the plasma concentration of each component at different time points was measured and the pharmacokinetic parameters were determined. The AUC0-24 h and Cmax of the phenylethanol components (salidroside, tyrosol, hydroxytyrosol) were the greatest, suggesting that these components are the main pharmacological substances of Ligustri Lucidi Fructus. In addition, the tmax values of the eight major components were even lower with administration of the wine-steamed product, suggesting that these components are rapidly absorbed. However, the tmax values of specnuezhenide and oleanolic acid were greater with administration of the wine-steamed product, indicating that these two components were more slowly absorbed. A secondary peak phenomenon of tyrosol and hydroxytyrosol were observed in two sample groups, whereas the secondary peak phenomenon of salidroside occurred only with the wine-steamed product. This result suggests that the effect of wine-steamed product could persist for a long period. Meanwhile, the relative bioavailability of specnuezhenide and oleanolic acid was greater than 100% with administration of the wine-steamed product, consistent with the Traditional Chinese Medicine theory of the wine-steamed product being more effective than the raw material. The results reveal the different pharmacokinetic parameters and relative bioavailability of each component of Ligustri Lucidi Fructus and its wine-steamed product, and also demonstrate the variation and correlation of various components in vivo and in vitro, providing an experimental basis for the selection of quality control indexes, mechanisms of processing and the metabolic rule in vivo of Ligustri Lucidi Fructus. These experiments were approved by the Ethics Committee of Institute of Basic Theory for Chinese Medicine, China Academy of Chinese Medicine Science.

Investigation of Host-guest Complexation Between 4-Sulfonylcalix 6 Arene and 15 Alkaloids from Traditional Chinese Medicines and Inhibitory Effect of Binding System on Proliferation of HepG2 and H9c2 Cells / 中国实验方剂学杂志

Objective:To investigate bonding ability between 4-sulfonylcalix ［6］ arene （SCA6） and 15 alkaloids （matrine， allomatrine， dauricine， daurisoline， quinidine， quinine， crotaline， vincristine， gelsemine， koumine， tetrandrine， aloperine， oxymatrine， sophocarpine and sinomenine）， and to evaluate viability<italic> in vitro</italic> of HepG2 and H9c2 cells with 12 alkaloids/SCA6 bonding systems （except allomatrine， oxymatrine， sinomenine）. Method:Fluorescence competitive titration was used to determine the binding constants of alkaloids and SCA6， the inhibitory effect of alkaloid/SCA6 complex on proliferation of HepG2 and H9c2 cells was investigated by cell counting kit-8 （CCK-8）. Result:All the 15 alkaloids had good bonding with SCA6 at the ratio of 1∶1 （the binding constants >1×10⁵ mol·L^-1， <italic>R</italic>²>0.98）， the aloperine （quinolizidine alkaloids） and SCA6 had the biggest binding constant （20.55×10⁶ mol·L^-1）. In addition to gelsemine， crotaline， matrine and sophocarpine， 8 alkaloids （including aloperine， tetrandrine， dauricine， daurisoline， quinidine， quinine， vincristine and koumine） exhibited significant anti-tumor effects on HepG2 cells. Except for daurisoline， the anti-proliferation effect of the other 11 alkaloids before and after binding with SCA6 had no difference in HepG2 cells. In addition to gelsemine， crotaline， matrine and sophocarpine， the anti-proliferation effect of the other 8 alkaloids before and after binding with SCA6 had no difference in H9c2 cells. Conclusion:SCA6 shows intense binding ability with bisbenzylisoquinoline， quinolizidine and indole alkaloids. It can improve the solubility of alkaloids without affecting their anti-tumor activity， which provides a reference for subsequent related applications of SCA6 as a drug delivery carrier.

Mechanism of Dahuang Zhechongwan Against Multiple Organ Fibrosis： A Review / 中国实验方剂学杂志

Dahuang Zhechongwan （DHZCW） is a classic prescription from the Jingui Yaolue（《金匮要略》） by ZHANG Zhong-jing，with the effects of tonifying deficiency， relaxing the middle， promoting regeneration， and resolving stasis. It has been widely used in the clinical treatment of various diseases with definite efficacy achieved. The research on multiple organ fibrosis has shown that DHZCW can slow down the development of organ fibrosis in the heart， liver， kidney， lung， etc.， and good results in both clinical practice and experimental research have been obtained. The present study reviewed the previous investigations on the experimental mechanism of DHZCW in the treatment of multiple organ fibrosis and revealed that the pathogenesis was closely related despite different disease sites. From the perspective of traditional Chinese medicine （TCM），these diseases shared a common pathogenesis，which was manifested by deficiency. Long-term diseases led to the formation of "dried blood". From the perspective of modern medicine， the diseases all showed pathological changes in the deposition of extracellular matrix （ECM）， and their occurrence and development were all based on certain effector cells ［such as hepatic stellate cell （HSC） and pancreatic stellate cell （PSC）］， with same cytokines ［such as tumor necrosis factor-α （TNF-α），interleukin-6 （IL-6），IL-1β，and α-smooth muscle actin （α-SMA）］ and some key pathways ［transforming growth factor-β1 （TGF-β1）/Smad， phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt）， and lipopolysaccharide （LPS） paracrine and autocrine mechanisms］ involved. As a classic prescription for "deficiency-induced dry blood"， DHZCW was effective in treating fibrosis， which was presumedly related to the inhibition of ECM deposition by intervening in the above-mentioned mechanisms， thereby delaying the disease progression. This study is expected to provide literature support to clarify the scientific connotation of DHZCW in the treatment of multiple organ fibrosis and lay a foundation for further experimental and clinical research.

Systematic review and Meta-analysis of efficacy and safety of acupuncture therapy on hypertensive intracerebral hemorrhage / 中国中药杂志

To systematically review the efficacy and safety of acupuncture combined with minimally invasive surgery or basic the-rapy in treating hypertensive intracerebral hemorrhage(HICH) patients compared with minimally invasive surgery or basic treatment. In this study, the four Chinese databases, the four English databases, Chinese Clinical Trial Registry and ClinicalTrail.gov, all above were systematically and comprehensively retrieved from the time of database establishment to September 10, 2020. Rando-mized controlled trials(RCTs) were screened out according to inclusion criteria and exclusion criteria established in advanced. The methodological quality of included studies was evaluated by the tool named "Cochrane bias risk assessment 6.1". Meta-analysis of the included studies was performed using RevMan 5.4, and the quality of outcome indicators was evaluated by the GRADE system. Finally, 17 studies were included, involving 1 852 patients with HICH, and the overall quality of the included studies was not high. According to Meta-analysis,(1)CSS score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=-3.50,95%CI[-4.39,-2.61],P<0.000 01);(2)NIHSS score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=-4.78,95%CI[-5.55,-4.00],P<0.000 01);(3)the cerebral hematoma volume of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=-4.44,95%CI[-5.83,-3.04],P<0.000 01);(4)ADL score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=20.81,95%CI[17.25,24.37],P<0.000 01);(5)the GCS score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=2.41,95%CI[1.90,2.91],P<0.000 01). The GRADE system showed an extremely low level of evidence for the above outcome indicators. Adverse reactions were mentioned only in two literatures, with no adverse reactions reported. The available evidence showed that acupuncture combined with minimally invasive surgery or basic therapy had a certain efficacy in patients of HICH compared with minimally invasive surgery or basic therapy. However, due to the high risk of bias in the included studies, its true efficacy needs to be verified by more high-quality studies in the future.
