Anti-tumor Mechanisms of Bruceine D： A Review / 中国实验方剂学杂志

Malignant tumors seriously threaten human life and health. Radiotherapy and chemotherapy are the conventional methods for the clinical treatment of advanced tumors. The prognosis and efficacy are still far from satisfactory due to the radiotherapy has serious adverse effects on the body and the chemotherapy often causes problems such as tumor resistance and cell proliferationinhibition. Therefore， the search for new， safe， and effective anti-tumor drugs and the elucidation of their molecular mechanisms are effective measures for clinical treatment of tumors and improvement of patients' quality of life. Active ingredients derived from Chinese herbal medicines and natural products have gradually become a hot spot in the research and development of anti-tumor drugs due to their multi-target and multi-channel anti-tumor pharmacological activity characteristics and their advantages such as less adverse reaction on the body. Bruceine D is a class of tetracyclic triterpenoids extracted from the fruit of the Chinese herbal medicine Bruceae Fructus， with anti-inflammatory， anti-malarial， anti-parasitic， and other pharmacological activities， and its anti-tumor activity is particularly significant. Pharmacological studies have found that bruceine D can regulate various cellular physiological activities such as proliferation， apoptosis， invasion， and migration of lung cancer， liver cancer， pancreatic cancer， intestinal cancer， and other cancer cells by targeting different signaling pathways. Bruceine D can be used in combination with other chemotherapeutic drugs to improve the sensitivity of tumor cells to chemotherapeutic drugs， thereby reducing the adverse effect of chemotherapy. Clinical application practice has shown that Bruceae Fructus oil emulsion injection containing bruceine D has significant advantages in the efficacy and safety of tumor treatment. Although there are many studies on the antitumor pharmacological activity of bruceine D and its clinical efficacy is significant， the specific antitumor molecular mechanism of bruceine D is still unclear， and there is a lack of systematic review on the existing antitumor mechanism of bruceine D. Therefore， based on the research on bruceine D in China and abroad in recent years， this paper reviewed the anti-tumor effect and related molecular mechanisms of bruceine D from six aspects， namely， tumor cell proliferation， apoptosis， metastasis and invasion， glucose metabolism process， autophagy， and chemotherapy sensitivity. This paper is expected to provide a pharmacological basis and scientific reference for the antitumor drug development and clinical application of bruceine D.

Zhuanggu Guanjie herbal formula mitigates osteoarthritis via the NF-κB transduction mechanism.

The Zhuanggu Guanjie herbal formula has been a famous Chinese prescription for treating bone diseases since time immemorial. The anti-osteoarthritis (OA) properties of this botanical prescription are well documented in the Chinese Pharmacopoeia. However, the detailed mechanisms behind the phenomenon have not been elucidated. Hence, we aimed to investigate the anti-OA efficacy of the Zhuanggu Guanjie herbal formula and its underlying mechanism. The anti-OA properties of Zhuanggu Guanjie capsule (ZGC) were determined by the cytokine contents and inflammatory-related proteins, which were measured by RT-PCR, flow cytometry, Western blot, and laser confocal assay in ATDC5 cells. The levels of interleukin-6, tumor necrosis factor-α, inducible nitric oxide synthase, cyclooxygenase-2, and prostaglandin synthesis E2 have been markedly reduced after being treated with ZGC for 48 h in a dose-dependent manner. Furthermore, ZGC prevented the translocation of NF-κB from the cytosol to the nucleus. On the other hand, we used the mono-iodoacetate (MIA)-induced OA model to confirm the in vivo efficacies of this herbal formula. Oral administration of ZGC attenuated MIA-induced OA damage through changes in histopathological and knee joint volumes. The serum matrix metalloproteinase-13 contents in the ZGC treatment group declined as compared to those in the MIA model group. Through our in vitro and in vivo studies, we confirmed the anti-OA efficacy of ZGC and uncovered its detailed mechanism, and this treatment shed light on OA pathophysiology.

Can acupuncture enhance therapeutic effectiveness of antidepressants and reduce adverse drug reactions in patients with depression? A systematic review and meta-analysis / 中西医结合学报

BACKGROUND@#Some depressed patients receive acupuncture as an adjunct to their conventional medications.@*OBJECTIVE@#This review aims to provide evidence on whether acupuncture can enhance the therapeutic effectiveness of antidepressants for treating depression, and explore whether acupuncture can reduce the adverse reactions associated with antidepressants.@*SEARCH STRATEGY@#English and Chinese databases were searched for randomized controlled trials (RCTs) published until December 1, 2021.@*INCLUSION CRITERIA@#RCTs with a modified Jadad scale score ≥ 4 were included if they compared a group of participants with depression that received acupuncture combined with antidepressants with a control group that received antidepressants alone.@*DATA EXTRACTION AND ANALYSIS@#Meta-analysis was performed, and statistical heterogeneity was assessed based on Cochran's Q statistic and its related P-value. Primary outcomes were the reduction in the severity of depression and adverse reactions associated with antidepressants, while secondary outcomes included remission rate, treatment response, social functioning, and change in antidepressant dose. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to evaluate the overall quality of evidence in the included studies.@*RESULTS@#This review included 16 studies (with a total of 1958 participants). Most studies were at high risk of performance bias and at low or unclear risk of selection bias, detection bias, attrition bias, reporting bias, and other bias. Analysis of the 16 RCTs showed that, compared with antidepressants alone, acupuncture along with antidepressants reduced the Hamilton Depression Rating Scale-17 (HAMD-17) scores (standard mean difference [SMD] -0.44, 95% confidence interval [CI] -0.55 to -0.33, P < 0.01; I2 = 14%), Self-rating Depression Scale (SDS) scores (SMD -0.53, 95% CI -0.84 to -0.23, P < 0.01; I2 = 79%), and the Side Effect Rating Scale (SERS) scores (SMD -1.11, 95% CI -1.56 to -0.66, P < 0.01; I2 = 89%). Compared with antidepressants alone, acupuncture along with antidepressants improved World Health Organization Quality of Life-BREF scores (SMD 0.31, 95% CI 0.18 to 0.44, P < 0.01; I2 = 15%), decreased the number of participants who increased their antidepressant dosages (relative risk [RR] 0.32, 95% CI 0.22 to 0.48, P < 0.01; I2 = 0%), and resulted in significantly higher remission rates (RR 1.52, 95% CI 1.26 to 1.83, P < 0.01; I2 = 0%) and treatment responses (RR 1.35, 95% CI 1.24 to 1.47, P < 0.01; I2 = 19%) in terms of HAMD-17 scores. The HAMD-17, SDS and SERS scores were assessed as low quality by GRADE and the other indices as being of moderate quality.@*CONCLUSION@#Acupuncture as an adjunct to antidepressants may enhance the therapeutic effectiveness and reduce the adverse drug reactions in patients receiving antidepressants. These findings must be interpreted with caution, as the evidence was of low or moderate quality and there was a lack of comparative data with a placebo control.@*SYSTEMATIC REVIEW REGISTRATION@#INPLASY202150008.

Transcriptional profiling and network pharmacology analysis identify the potential biomarkers from Chinese herbal formula Huosu Yangwei Formula treated gastric cancer in vivo / 中国天然药物

Huosu Yangwei (HSYW) Formula is a traditioanl Chinese herbal medicine that has been extensively used to treat chronic atrophic gastritis, precancerous lesions of gastric cancer and advanced gastric cancer. However, the effective compounds of HSYW and its related anti-tumor mechanisms are not completely understood. In the current study, 160 ingredients of HSYW were identified and 64 effective compounds were screened by the ADMET evaluation. Furthermore, 64 effective compounds and 2579 potential targets were mapped based on public databases. Animal experiments demonstrated that HSYW significantly inhibited tumor growth in vivo. Transcriptional profiles revealed that 81 mRNAs were differentially expressed in HSYW-treated N87-bearing Balb/c mice. Network pharmacology and PPI network showed that 12 core genes acted as potential markers to evaluate the curative effects of HSYW. Bioinformatics and qRT-PCR results suggested that HSYW might regulate the mRNA expression of DNAJB4, CALD, AKR1C1, CST1, CASP1, PREX1, SOCS3 and PRDM1 against tumor growth in N87-bearing Balb/c mice.

Objective:To study the efficacy of integrative medicine on congenital muscular torticollis. Methods:From October, 2017 to September, 2019, 80 children with congenital muscular torticollis were divided into group 1 (n = 40) and group 2 (n = 40) according to different treatment schemes. Group 1 received comprehensive physiotherapy, including passive stretching, head control training, posture correction and family rehabilitation. Group 2 received Tuina in addition. Before and six months after treatment, the root mean square (RMS) of surface electromyography of bilateral sternocleidomastoid muscles in supine neutral position, neck rotation and stretch, and the range of motion of passive neck rotation and lateral flexion, and the angle of head deviation from the midline to the affected side were compared. Results:Before treatment, the RMS of sternocleidomastoid muscle in each position was lower in the affected side than in the healthy side (P < 0.01), and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side was less than that of the other side (P < 0.01) in both groups; however, no significant difference was found between two groups (P > 0.05). After treatment, the RMS of EMG of sternocleidomastoid muscle in each position, and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side improved (|t| > 3.290, P < 0.01) in both groups, and were better in group 2 than in group 1 (t > 2.401, P < 0.05); the angle of head deviation from the midline to the affected side significantly decreaed (t > 15.075, P < 0.001) in both groups, and was significantly less in group 2 than in group 1 (t = -4.971, P < 0.001). Conclusion:Integrative medicine is effective on infant with congenital muscular torticollis, which is superior to comprehensive physiotherapy only.

Phased Expression of Gene and Protein of NogoA and NgR in Rats with Spinal Cord Injury and Time Window of Electroacupuncture / 中国康复理论与实践

Objective To investigate the phased expression of gene and protein of NogoA and its receptor (NgR) that affects axon growth of spinal cord injury (SCI), and to explore the time window effect of electroacupuncture on SCI rats. Methods A total of 144 female Sprague-Dawley rats were randomly assigned to sham operation group (group A, n=48) and model group (n=96). In the model group, Allen's method was used to establish SCI rats model, and they were further subdivided into model control group (group B, n=48) and electroacupuncture group (group C, n=48). Group C received electroacupuncture on Dazhui (GV14), Yaoyangguan (GV3), bilateral Ciliao (BL32) and Zu-sanli (ST36) with loose-tight wave, for 20 minutes every day, one day, seven days and 14 days after modeling. The rats at every interventional therapy time were randomly subdivided into two subgroups, which accepted sev-en or 14 days of treatment. Groups A and B were killed and the injured spinal cord tissue was extracted one day, three days, seven days, 14 days and 28 days after modeling, group C at the corresponding time. The hind limb motor function was assessed with BBB score before all of rats were killed. Four samples at every time in each group were randomly selected to detect the expression of mRNA and protein of NogoA and NgR at different stage of SCI using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blotting. Results The BBB score began to increase 14 days after modeling, and significantly increased until 28 days after model-ing (P<0.05), compared with one day, three days and seven days after modeling in group B. The BBB score in-creased in group C than in group B at all the time points (P<0.05), except 14 days after electroacupuncture one day after modeling. The BBB score was higher as electroacupuncture intervening seven days and 14 days after modeling than that at one day after modeling in group C, and no significant difference was found between seven days and 14 days of treatment at either electroacupuncture time point (P>0.05). The expression of gene and pro-tein of NogoA and NgR in group B was in the increasing tendency after SCI, and was at the peak until 21 days af-ter modeling, and was higher in group B than in group A at each time point (P<0.01). The expression of gene and protein of NogoA decreased at all the time points in group C than in group B (P<0.05), except seven days of elec-troacupuncture intervening one day after modeling in the expression of NogoA mRNA (P>0.05). The expression of gene and protein of NogoA and NgR was lower as electroacupuncture intervening 14 days after modeling than one day after modeling in group C (P<0.05). There was no significant difference in the expression of gene and protein of NogoA and NgR between electroacupuncture intervening 14 days and seven days after modeling, and seven days and one day after modeling (P>0.05); as well as between seven days and 14 days of treatment at each time point (P>0.05). Conclusion Elerctroacupuncture could improve the hind limb motor function, which may associate with the inhibition of the expression of gene and protein of NogoA and NgR in injured spinal cord of rats after SCI. Elerctroacu-puncture is effective in the treatment of SCI at the early time, however, it is much better in the recovery stage.

Methodological research for the promoting effect of Dendrobium moniliforme on macrophage phagocytosis based on high-content screening / 药学学报

The aim of the present study was to explore a sensitive, stable and reliable method for evaluating the phagocytosis, in which RAW264.7 macrophages engulfed GFP-Escherichia coli was tested by high-content screening technology. The study was conducted to optimize the method in evaluation of traditional Chinese medicine in the promotion of macrophage function. By testing macrophages at different ratio of bacteria to cells (multiplicity of infection, MOI), and at different incubation time, we optimized a high content screening method and the experimental parameters to determine the impact of bacteria in macrophages (fluorescence intensity index = be swallowed bacteria/macrophages). The method was used to determine whether Dendrobium moniliforme (DM) have effects on macrophage phagocytosis. The results show that the index has a positive relationship with MOI values, and the highest index was observed at incubation time of 1.5 h. The optimized conditions was 1×104 cells/well with a MOI of 50:1 (bacteria:cells) with incubation of 1.5 h. Under this condition, the relative standard deviation (RSD) was less than 10% in the precision test. Using the method to detect DM regulating macrophage phagocytosis experiment results showed that in 0.31-2.50 g·L-1 concentration range, DM has a dose-response effect in promoting phagocytosis. We successfully established the method for evaluation of macrophage phagocytosis, and proved the activity of DM in promotion of macrophage phagocytosis.

In vitro balanced sustained-release of Panax notoginseng saponins controlled with various matrix materials / 药学学报

To explore the influence of matrix materials in complicate ingredients on traditional Chinese medicine and investigate the excipients selection model based on balanced release characteristics of multicomponents, the influence of HPMC (K4M, K15M, K100M) and Carbomer (934P, 971P, 974P) was illustrated by testing in vitro release of ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in Panax notoginseng saponins (model drug, PNS). According to in vitro release results of PNS matrix tablets in water and artificial intestinal juice, the release curves were analyzed with Peppas equation and simulating factor (f). Significant differences in k value and n value among ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 existed in various formulations. The release behaviors from various excipients could be described with Non-Fickian transport or super Case II transport pattern. The f2 values for ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in 971P matrix tablet containing 30% Carbomer 971P were 74.91, 53.45, 57.89 in water and 79.35, 55.51, 51.89 in artificial intestinal juice, respectively. The release profiles fit for the regulation of FDA. The result revealed that the balanced release rates of Rg1, Rb1 and R1 in 971P matrix tablet were obtained.

In vitro balanced sustained-release of Panax notoginseng saponins controlled with various matrix materials / 药学学报

To explore the influence of matrix materials in complicate ingredients on traditional Chinese medicine and investigate the excipients selection model based on balanced release characteristics of multicomponents, the influence of HPMC (K4M, K15M, K100M) and Carbomer (934P, 971P, 974P) was illustrated by testing in vitro release of ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in Panax notoginseng saponins (model drug, PNS). According to in vitro release results of PNS matrix tablets in water and artificial intestinal juice, the release curves were analyzed with Peppas equation and simulating factor (f). Significant differences in k value and n value among ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 existed in various formulations. The release behaviors from various excipients could be described with Non-Fickian transport or super Case II transport pattern. The f2 values for ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in 971P matrix tablet containing 30% Carbomer 971P were 74.91, 53.45, 57.89 in water and 79.35, 55.51, 51.89 in artificial intestinal juice, respectively. The release profiles fit for the regulation of FDA. The result revealed that the balanced release rates of Rg1, Rb1 and R1 in 971P matrix tablet were obtained.
